Re: diff question
I assume what you really want is to ignore all comment lines completely (not just changes to comment lines).

Re: usage tracking
iptables can do traffic accounting (I think Lisa gave some good pointers there), but you might also want to *control* the bandwidth usage (say throttle to a low speed when you get over 80% of your limit, or block YouTube after it consumes XX% of the limit). For that the tc utility may be used to manage the IP traffic control features of the Linux kernel on your gateway box. TC is fairly complicated (unless you read about traffic queuing disciplines for fun), and the only GUI tool I know of, ktctool(http://ktctool.berlios.de/) is a bit old; last updated in 2006. You might be able to find a few other ui options with some careful google searching (rather high junk ratio in a couple test searches I did).

Re: mk802, g-82
The Roku Stick, and many phones, use MHL-compatible ports; CEC is the remote-control interface for MHL, but it's the MHL port that is required for a Roku stick.

Re: mk802, g-82
I'll answer the 2160p question: 2160p is 4K UHD resolution (http://en.wikipedia.org/wiki/2160p). This probably doesn't fit your preferences (particularly the load a distro part), but it doesn't get much simpler than a Roku stick (http://www.roku.com/streamingstick) if you have a TV with a MHL compatible HDMI port, and the remote is the TV's remote (also, there's a smartphone app).

Re: What benefit .png over .jpg?
TL;DR, If you just want to have an image you can view and you want a smaller file size, then use JPEG and don't edit it. If you want to edit the image or it's very small and speed of display is important, use PNG. The two file formats are quite different: PNG is *lossless* which means that you can edit, adjust, etc... the file without losing any image data. It stores all of the data in compressed form, so it's larger, but everything from the original image is still present. JPEG is *lossy* it actually discards around 90% of the image data, so you can't edit a JPEG without losing some of the image quality; by the third or fourth edit a JPEG gets pretty bad. It also uses some fairly complex math to store and reconstruct the image, so it's much more computationally intensive to view a JPEG compared to a PNG. The system (generally) uses PNG for thumbnails because (for small images) PNG is generally faster to create and faster to load due to less computation needed to compress/decompress data versus reconstructing an image from mathematical models. Hopefully that helps clarify the differences. On 10/04/2012 03:43 PM, j...@actionline.com wrote: What (if anything) is the benefit of .png image files over .jpg image files?

Re: What benefit .png over .jpg?
PNG addressed two problems with GIF. 1) GIF is an 8-bit format with an indexed color palette. It's possible to do 24-bit color by overlaying a red, green, and blue image mask, but it's not ideal. PNG is true 24-bit color with better compression. 2) GIF was, for a time, covered by patents on it's LZW compression, held by UNISYS that limited it's use in many situations. Those patents are expired in 2003/2004 and there is no longer any patent encumbrance for GIF or LZW compression. GIF has built-in support for animation, which PNG does not. MNG provides animation of PNG images, and APNG provides a more recent alternative animation mechanism for PNG images that's easier to create but less efficient in compression. I definitely agree that resolution matters most when printing. A 1080p screen displays a 2 megapixel image, so more than that is not usually helpful for onscreen display (4 megapixel is fine for the rare 4K display). I don't worry much about file size with 32G thumb drives and SD cards now common. I figure 4,000 images (8 megapixel PNG) on a single thumb drive or SD card is more than enough storage for away-from-home use, and at home 2TB backup drives are pretty cheap these days. BTW, typically 48 megapixel at 32-bit color (24 bits plus 8 bit alpha) is considered the minimum to match 35mm film. The biggest remaining problem in digital is dynamic range (quality film is usually 3-5 stops, digital struggles to get 2). The resolution difference isn't considered a big deal in most print publications (AZ highways is an exception, for good reason), so almost all professional photography is currently digital capture and workflow. On 10/04/2012 05:29 PM, Derek Trotter wrote: Higher resolution allows for printing large pictures while maintaining picture quality. A few years ago I saw an article in Arizona Highways showing why they don't accept pictures in digital format. The had two photos of the same tree. One taken on film and one taken with a digital camera at several megapixels. Both looked equally as good. Then they blew up a small portion of the image. The film version looked great. The digital version was obviously of poor quality. The article went on to say what resolution was needed to equal the quality of 35mm film. I forget the number, but it was way higher than what was commonly available at the time.

I take all my snapshots at about 1/2 megapixel jpg and then crop and further resize everything down to about 1/4th the original size, and I can't tell any difference in image quality, even with a jeweler's loop. I've sometimes printed an original and a resized smaller version at Costco and asked people to tell me which is better, and I've never found anyone who could tell any difference. People send these 3-megapixel (and bigger) images to me all the time and they are really slow to load. So, I've always used imagemagick 'convert' to bulk resize everything to about 1-20th the original size and they all look the same to me. On a recent vacation, I took more than 1,000 snapshots and by resizing them, they all fit on a single CD with lots of room to spare. I also upload our travel pix to a web page for our family to view online and by reducing the image size, all the images load and display very quickly and beautifully online.

Re: OT: Google Voice question.
I think you misunderstand what Google Voice is. 1) It is NOT voicemail. It has voicemail, but it's intended to function opposite to a voicemail service. 2) People should be calling your Google Voice number directly; it then forwards to (rings) one or more actual phones (home phone, cellphone, gmail, etc...) and redirects to voicemail if you don't pick up. The idea is that you give everyone your Google Voice number, but not your home or cell number(s). Then you can change home or cell service without impact to people who want to call you. You also gain control options, such as setting some callers to only ring through on weekdays, or setting some callers to ring the home phone but not the cellphone. So the reason it doesn't work the way you want is that your concept has it behind your normal phone; it's actually the reverse in that your normal phone is *behind* Google Voice.

Re: programming
I would start with Python/Django (for a faster start) or Java (for a stronger foundation if you don't need to be working right away). The JavaScript world seems to be moving more towards templating (e.g. Dust) and other tactics to focus more on the graphic design work for the browser tier and keep the bulk of the programming on the server tiers, so I'd be reluctant to invest in that language right now. For Python make sure you're learning 3.x, for Java make sure you're learning good fundamentals of Computer Science and the Java version taught is 6 or 7. For Mike's situation I'd recommend something with a fast start, and Python/Django or Dust/JS are very good choices in that regard.

Re: Laptop Battery Life
The full discharge-and-recharge was for NiCd batteries, and helped to limit memory effect, it does not apply to NiMH or LiIon batteries (anything fairly recent), nor did it ever apply to lead-acid and it's derivatives. LiIon is the only one that has particularly big problems if discharged to 0%; although it's best to not leave any battery fully discharged too long, for various reasons depending on chemistry. It *used* to be that chargers were quite dumb and just shoved charge into a battery. Most good quality chargers are much more nuanced than that today, and will charge at different rates depending on the charge state of the battery which further extends life. Most laptops, in particular, have quite intelligent chargers and will not overcharge the battery or charge too fast/too slow for the charge profile; this is particularly important for LiIon as overcharge and overly aggressive charge/discharge can result in thermal runaway (c.f. the various laptop explosion videos). So, for LiIon, just charge it when you need to, and if you intend to store it for a while, discharge a bit (around 80%) and check it now-and-then to make sure it gets recharged before it drops much below 30%. For NiMH, it's a bit more nuanced, but still amounts to charge-it-when-you-need-to, just not as much to worry about when storing as long as it doesn't spend too much time completely discharged. For both LiIon and NiMH, there are several common chemistries used (both are families of battery, not particular implementations), and each has different advantages and disadvantages. It's worthwhile checking which you're dealing with if you wish to maximize the life of your particular device. These wikipedia articles have some very good details on the chemistry, including some of the differences for recent alternate chemistries. http://en.wikipedia.org/wiki/Lithium-ion_battery http://en.wikipedia.org/wiki/Nickel%E2%80%93metal_hydride_battery I hope that helps, Rusty.

Re: Laptop Battery Life
Current Li-Ion chemistry is much improved from a few years ago, and self-discharge rates are a lot lower (hence the amount of charge left after 6 months). It's fine to keep the battery in a drawer (cool/dry, of course) and charge every 6 months. They will probably last longer, but perhaps not for the reason you would expect. You also have to accept that you loose the advantage of the built-in UPS-like behavior of a laptop with a battery, but if you have an external UPS, you may be OK with that. For storage you actually want to partially discharge the battery (to 80%) before putting it away; Li-Ion has self-damaging chemistry at both 100% and 0% (whiskering and swell-cavitation), so you want to discharge to 80% before storing it, then charge back to 80% before it drops below 30% (typically 6-9 months, check it monthly to be on the safe side). Recent systems won't cook a battery, the charge circuits automatically avoid overcharge, but any (commonly available) Li-Ion kept at 100% charge for too long will develop internal shorts due to the whiskering effect of high charge separation combined with corrosive internal chemistry. Whiskering does take a rather long time, however, typically 3-5 years for good quality batteries.

Re: hacking an android tablet to single function device
It is possible to kiosk an android device, and it doesn't require a special build. The application must be an Android application, and must implement a certain interface. Basically, you just replace the application that provides the home screen (desktop as you described it) with your own app that simply launches the kiosk application [1]. If you have an app in mind that doesn't work that way, just write your own app to fulfill the requirements then launch the app you want to run (or use one of several open-source demo/kiosk mode apps [2]). The ARM support for direct execution of Java bytecode is a hardware acceleration technique, it does not change the requirement for a JVM. In recent (e.g. ARM8 or later) chips it doesn't even provide a performance boost because the implementation is a trivial translation (http://en.wikipedia.org/wiki/ARM_architecture#Jazelle). I'm a bit time-constrained recently, but perhaps in late summer I could provide the instructional talk you've requested, I have to see how it looks in a few months. ==joseph++ Note: the below links are semi-random, I did not vet the applications due to time constraints, I just hunted down a few representative links, so DO NOT trust these links just because I list them.

Re: OT: SSD and EMP
This is correct. EMP will kill SSD easier than even the chips or magnetic media. This is primarily because EMP will induce a capacitive load in the floating gate of the NAND cell; this will turn every bit in the chip to a '1'. SSD floating gate charge is extremely small, so it doesn't take much of an EMP to wipe the devices. Place any *unshielded* SSD within 3 meters of a 1000KV power line for a couple seconds and you'll see the same effect. That said, many actual internal SSD drives (as opposed to flash media, USB drives, or mSATA drives) are available with conductive and grounded cases; those would probably not loose data as they're, effectively, inside a Faraday Cage structure already (as long as the ground connection is sufficiently conductive).

Re: LaTop battery care and life expectancy
All Lithium-Ion batteries have similar issues and, in general, similar recommendations for care. Keep in mind, however, that different chemistries produce very different results, lead acid is very different from NiCd, NIMH, or LiIon. Different batteries using the same general chemistry may still have very different specific chemistry to meet particular cost/current/charge/voltage characteristics. Lithium ion, for example, has at least 8 primary chemistries (e.g. LiPo, LiFe, LiZnCo, etc...), each with a hundred or more variations. Solar systems often use deep-cycle lead-acid because it is cheap, mature, and very rugged. That makes comparing solar experience to laptops somewhat difficult. Some newer Lithium Ion batteries use new chemistry (e.g. Si cathodes in charge-carrier flexible polymer matrix to accommodate swelling during charge/discharge) to adapt to the issues below, but all still face the same challenges to a greater or lesser extent. 1) Lithium Ion involves actual absorption and release of Lithium atoms by anode and cathode. This means that there is physical stress on the battery elements, and over time this will damage the materials. Deep discharge cycles and higher current drain will make these happen faster. Your cellphone battery has low current drain and long cycles, compared to a laptop, and will tend to last longer as a result. Letting your battery fully discharge before charging it will cause damage, but LiIon also has an explosive chemistry, so power management circuitry manages the battery, and turns off a phone when there is still about 20% charge left in the cell to mitigate this for cellphone batteries. The ideal usage is to charge at about 30% and not leave the cell above 70% for too long (see issue 2 for the reason). 2) Lithium Ion current limits are dependent on the Li mobility, which requires highly solvent electrolytes to permit high current usage. This means that the anode and cathode materials will dissolve in the electrolyte over time, and, because of the electrical potential between anode and cathode, will form whisker structures that eventually short across the gap between the electrodes. Leaving the cell fully charged for a long time (or constantly charging it when not in use) will encourage these whisker structures to grow because it maintains a higher potential between the electrodes. This is why leaving a battery in a charger for a long time (months or years depending on the battery and charger) will eventually result in a dead battery, even though it was never really used. Modern charging circuitry could account for this by discharging the battery periodically, but laptops and other consumer-oriented devices generally do not in order to maintain immediate readiness for on-battery use while charging. The recommendation is to actually use the device powered by the battery from most of the time, and only add A/C power to recharge, when planning to disconnect in the near future, or when usage duration is reasonably expected to exceed battery life (even then starting on battery and adding A/C when charge drops below 50% often helps). It's also best not to leave a laptop always connected to power, and only plug in when charging is actually needed. In the end, the reason a cellphone battery often lasts so much longer than a laptop battery (typically 2-3 times as many charge/discharge cycles) is more about the different power requirements of the two uses and the specific structure and chemistry choices made to match battery to load. Research is constantly advancing battery and other electrical energy storage technologies, so the performance one may expect for a given usage are constantly changing, and different manufacturers may use very different approaches to meet specific cost and performance criteria. This makes comparing, or even predicting, battery life very difficult, to the point of being little more than a guess, so the best advice I know is to simply use the device in a reasonable manner, and keep an eye on the lifespan indicator via the battery information probe available in Linux so you have some advance warning when you'll need to purchase a new battery. ==Joseph++ On 10/09/2011 01:22 PM, keith smith wrote: I've had several laptops and battery longevity has always been an issue.� Not how long it will run my laptop before completely discharging, but how long it will be before that battery is no good.� What I do not understand is why or how a battery can go bad from being in a laptop that is plugged in and why there is a overcharging issue. � I have two frames of reference, maybe three.� My cordless phone battery lasts for years.� I recently started researching solar power.� Seems some think the battery's life is extended by not draining it and having a constant change trickling into it.� One of the videos said the life of the battery was in cycles.

Re: LaTop battery care and life expectancy
All lithium-ion charges must shut off charging once the cell is full. They actually have to manage to the limitations of the least capable individual cell in a pack, so it's a little less than that for laptop packs. Because lithium is subject to thermal runaway (i.e. the pack can burst into flames if not managed properly) you cannot just dump power into it without detecting full charge and shutting off. You actually have to watch heat build up as well, and most (if not all) cells have a thermal sensor that reports to the charging circuit to avoid overheating the cell during charge or discharge.

Last I checked XFS was still supported; when tuned correctly it's still the fastest filesystem for database transaction logs (although some of the log-structured filesystem may eventually beat it). EXT4 still has some significant performance issues and has regressed quite a bit in that regard in the past few kernels. I just rechecked, and XFS support in RHEL/CentOS is part of the high-performance/high-scalability add-on in RHEL 5.6, and became fully supported in 5.7 (although it has been supported for a long time in the kernel), but there's no reason not to use it in CentOS 5.6 unless you have a paid support contract and didn't pay for the high-performance/high-scalability add-on (if that's even offered by your particular vendor). XFS is also probably the most stable Linux native filesystem (other than EXT2/EXT3) as it's been in the kernel about as long as EXT3 and still has active development effort to improve quality/reliability/performance.

Re: rootkits
What you see below is false-positives. The files in /usr/lib are normal files used for things like initialization control (pymodules) and JDK selection (jvm). The files in /dev/shm are pulsaudio temporary device files, and like everything in /dev/shm will disappear on a reboot (/dev/shm is a filesystem interface to shared memory). The hidden directories are likewise normal (java, udev, initramfs) elements of the system. That's why these things are warnings; they *might* be a problem, but the software has no way to be sure (although it really should have exceptions built-in for things like pulseaudio, udev, and initramfs stuff). Then again, it's fundamentally impossible to know if a system is clean from within that system (since a rootkit could just intercept any call that would expose it's presence and return a false result).

Re: What are the most stable distros?
On the RedHat side, RHEL and it's derivative CentOS are the stable systems. Both are targeted at Enterprise use where stability far outweighs updates. That said, RedHat does backport some new features and applications when there is sufficient demand in the enterprise space. On the Debian side nothing is more stable that Debian Stable (Currently Squeeze released a few months ago). Ubuntu LTS releases are *supposed* to be stable but in practice the Debian upstream is more stable. In either case, the system will only have a new release every couple years at most (sometimes 3-5 years go between stable releases of RHEL or Debian), so you *will* eventually encounter missing features and/or new applications that simply won't run on the stable distributions. If stability is your primary consideration, I'd go with RHEL/CentOS or Debian Stable. If you want a more simple/minimal desktop, then use a desktop based on XFCE or LXDE if you need compatibility. If you just want the most minimal GUI possible, then something like JWM, WindowMaker, or similar minimalist GUI environments may work well for you. The following are my general recommendations for stability vs. up-to-date, note that the complexity of these starts with anyone can manage this, and ends with expert-only/you'd better have lots of free time: If you want a more balanced approach between stable and up-to-date, then Ubuntu LTS releases, some Fedora releases, and certain LinuxMint releases (the ones based off of stable or LTS releases) will likely fit the bill. If you want new features and applications faster, but don't want to learn new desktop paradigms all the time and want something a smidge more tested, then consider a distribution based from Debian testing (such as the upcoming LinuxMint releases), a current Fedora release, or *most* Ubuntu releases (delay upgrade by a month or two and read the forum posts to see how stable it is). If you want the most bleeding edge possible, then something from Debian Unstable (such as Sidux), some Ubuntu releases, a Fedora release candidate, or a Gentoo-type system may be for you. If you want absolute control over what is updated and when, then you can install Debian Stable and run your own Debian package proxy mirror (and only bring in packages when you want them), install Fedora and your own Fedora package proxy mirror (same update policy), or use Gentoo and only emerge what you want and when you want (and handle the dependencies yourself). If you want down-to-the-metal absolute control over every aspect of the system, build your own distribution per Linux From Scratch or something similar and build all applications from source (and handle all dependencies, build issues, etc. yourself).

Re: Need Help Cloning a Drive
I feared this might be the case; clonezilla just isn't quite ready for the new sector sizes. The best suggestion I can make from here is to create a partition table by hand on the destination drive that has the partition sizes and layout you want, then transfer the data one partition at a time. You'll probably have to install GRUB in the MBR on the new drive to make it bootable. Someone else here probably knows how to do this better than I do, but here's my take: 1) transfer all the data 2) remove the old drive and put the new drive in place 3) boot from a live rescue type CD (the latest system rescue CD works well here) 4) mount the new drive root partition and chroot to it's mount point. 5) check and adjust /etc/fstab to mount all of the other partitions in the correct places. Make sure you use UUID's for this, as System Rescue CD creates odd device names sometimes. 6) mount everything like you would when running (this may not be required, but it's just for completeness) 7) check everything looks like you expect. 8) verify /boot is correct and has the correct kernel(s) 9) check your grub configuration in /etc 10) run the grub installer and grub configuration to install GRUB on the MBR of the new drive, and setup the GRUB menu/configuration/modules to boot properly. 11) exit the chroot, shutdown the system, pull out the rescue CD, and reboot. *) You should now have a bootable clone drive, if everything worked. Note: If you have Windows in dual boot on the old drive it almost certainly won't be bootable on the new drive and will need to be reinstalled.

Re: applet clock ext hdd
I can't help with the clock; I just adjust the settings on the default clock applet and it displays how I like... For an EXT hard drive for backup, there are a couple of options: 1) low-cost USB drive from the likes of Western Digital, Seagate, or similar. a) Cheap ($100/TB or less). b) Slow and you have to remember to connect/disconnect properly. 2) eSATA enclosure. a) A bit more costly (around $150/TB) b) Fast and you can leave it connected from boot-to-shutdown on desktops all the time. Either way, I'd recommend a single large partition (EXT4 or XFS, XFS is far more stable, but EXT4 has newer features). For backup, you can rsync to a directory named for the date under a main backup directory (e.g. /media/backup_disk/MyBackups/20110716T19/). This has several advantages over using a lot of small partitions: 1) Using different directories on a single partition makes it easier to manage all the data (plus you don't hit the limits on the number of partitions permitted on a device). 2) It avoids the problem of figuring out which partition to mount for a backup without mounting them all and searching through the contents. 3) It makes rotation simpler (just delete anything more than X days old after a backup if the disk is getting more than Y% full). 4) With the right directory names (like the example above) you can find the most recent backup easily as well. a) just list them (ls -lh), the last one listed will always be the most recent if you use a format that sorts correctly. As far as what drive to buy, I'd get one of the following (in no particular order): *) Western Digital MyBook Essential 3TB (on sale this week and next at Costco and BestBuy for $129) *) Western Digital MyBook Essential 2TB ($99 at BestBuy) *) Western Digital Elements 2TB ($99 at BestBuy) *) Seagate FreeAgent GoFlex Desk 2TB ($102 at BestBuy) *) Toshiba 2TB External USB 3.0 ($110 at Best Buy) *) Toshiba 1TB External USB 2.0/eSATA ($80 at BestBuy) You might also consider the (Buffalo Technology LinkStation Live 1TB) as a cost-effective NAS alternative (it's $130 at BestBuy). That would allow you to keep your backups elsewhere in the house (anywhere your LAN cables, no wireless, reach). You'd have to mount the network share from the NAS to a directory on your desktop, and just rsync to a subdirectory under that; no muss/no fuss. It's not lightning fast to do things that way, but it's relatively simple and easy to set-and-forget.

Re: Re ext hdd
rsync will treat each dir as a separate backup; you'll want to rotate to new directories only when you want to move to a new backup (e.g. each month or so). The filesystem on the destination does not have to match the filesystem on the source (so it's OK to have ext3 on your homedir and back that up to XFS). The main backup dir would be the directory that contains all the rotating backup directories. e.g. (MyBackups is the main backup directory in this example) /media/backup_disk + | MyBackups |+ | 20110716T19 | 20110816T19 | 20110916T19 | 20111016T19 That way you use rsync to keep a current backup in the latest directory and every so often (perhaps monthly) you start a new directory. The first backup in each directory takes a while (consider that a full backup) while it only takes a few minutes to update each (e.g.) day until the next full backup. That way you have a longer backup window (several months) when you can recover something lost or accidentally deleted. I don't know the details of your current process, so I'm basing this off of your description of what you had planned to do with partitions. The command to make each monthly directory would look something like this: mkdir -p /media/backup_disk/MyBackups/$(date '+%Y%m%dT%H%M') or this if you don't want the time in the directory name: mkdir -p /media/backup_disk/MyBackups/$(date '+%Y%m%d') On 07/16/2011 08:44 PM, betty wrote: Thanks, your response - was very clear. only thing i'm not sure about is the naming a main back up directory. so does that mean that after i format it for ext4 or xfs that i make a dir. called /media/backup_disk/MyBackups/20110716T19/). ? then on subsequent back ups i name them for example /media/backup_disk/MyBackups/20110816T19/).(note month change) what prevents rsync from thinking that this is a whole new dir?

Re: need help installing to a USB stick
If you can run the usb-creator-gtk program (apt-get install usb-creator-gtk), that will install from any ISO; it doesn't have to be the system you're using. It's a gui, however, so not ideal, but it's easier than trying to do a standard install on a USB drive. The installer takes about 1G, just allocate *all* of the rest of the drive to the reserved extra space and your rommate should be able to go forward from there with no major issues (as long as they don't dump too much stuff on the drive, 8G runs out kind of fast if you're not careful). You can start it with usb-creator-gtk --iso=path-to-your-.iso to make for a little bit less screen reading work. Just download the kubuntu iso and use the above program to install it on your rommate's USB stick, and you're good to go.

Re: Looking for NAS Hardware Recommendations
The info folder is used by the web interface; don't delete that unless you'd
like to reload the device from scratch ;)
The correct value should be array1_Hshare. array1_Hshare is the rsync
top-level module name, not a directory.
The issue you're seeing sounds like a case-match issue or something similar.
The module will be exactly array1_ followed by the (initial) name of the
directory on the array.
If you initially put spaces in, or changed the name, then you'll have a hard
time figuring out the module name because it's based on the first name you give
for the share; it doesn't get updated if you change the share name later.
Also, if you changed the RAID settings, then try using array2 or array0, just
in case it changed the array numbering.

It's not in the manual, but the BuffaloLink mechanism that allows one NAS

You can rsync to the box (to do backups) with the following pattern:
rsync ${OPTIONS} rsync://${BACKUP_SERVER}/array1_${SHARE_NAME}/${DIR_NAME}
In order to create anything on the NAS without rooting the device, you need
to go into the web admin screen and setup Samba (i.e. Windows) share's.
That creates the directories at the top level of the RAID array
(${SHARE_NAME} above). It also creates the rsync endpoints.
I setup a shared folder on the NAS called Hshare. It is setup as a Windows,
Apple and ftp shared folder. The ftp is so I can see if the file is
there.yes, I should root the device to ssh into it, but I thought I
would give this a try first.
I then tried to rsync a file to the NAS box with this command:
rsync -tlzv file_name rsync://xxx.xxx.xxx.xxx/array1/Hshare/
and got this error:
unknown module 'array1
I then re-read your post carefully...;-) and tried this command
rsync -tlzv file_name rsync://xxx.xxx.xxx.xxx/array1_Hshare/
and got the error: unknown module 'array1_Hshare'
When I ftp into the box, ftp://xxx.xxx.xxx.xxx, I see two folders, array1
and info. When I drill down into array1 I see the Hshare folder.
Your email said to use array1_share-name, and the rsync man page says
array1/share-name as far as I can tell. Neither worked. What am I missing?
Thanks!
Mark
P.S. There is a lot of stuff in the info folder that appeared after I set up
the RAID1. Do I need it? Can I delete it?

The following all return 'unknown module' regardless of what name I put after the url (array1_fred, , array0_fred array2_fred) rsync some_file rsync://xxx.xxx.xxx.xxx/array1_fred/ or a '/' instead of a '_' returns the same error for module array1, array2, array0. I also tried Array[0,1,2] with the same result. Some of the web pages show the name as Array 1, so I tried the capital A and a space, but still not luck. When I ftp into the box, the path to fred is xxx.xxx.xxx.xxx/array1/fred. I tried restarting the Linkstation, and no change. I also tried the alternative rsync format, rsync some_file xxx.xxx.xxx.xxx::array1_fred, and that did not work. Any more ideas on how to get rsync to work? Thanks!

The issue you're seeing sounds like a case-match issue or something similar. The module will be exactly array1_ followed by the (initial) name of the directory on the array. If you initially put spaces in, or changed the name, then you'll have a hard time figuring out the module name because it's based on the first name you give for the share; it doesn't get updated if you change the share name later. Also, if you changed the RAID settings, then try using array2 or array0, just in case it changed the array numbering. --- PLUG-discuss mailing list - PLUG-discuss@lists.plug.phoenix.az.us To subscribe, unsubscribe, or to change your mail settings: http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss --- PLUG-discuss mailing list - PLUG-discuss@lists.plug.phoenix.az.us To subscribe, unsubscribe, or to change your mail settings: http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss signature.asc Description: OpenPGP digital signature --- PLUG-discuss mailing list - PLUG-discuss@lists.plug.phoenix.az.us To subscribe, unsubscribe, or to change your mail settings: http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss
Re: Looking for NAS Hardware Recommendations
It's not in the manual, but the BuffaloLink mechanism that allows one NAS to
backup another is rsync.
You can rsync to the box (to do backups) with the following pattern:
rsync ${OPTIONS} rsync://${BACKUP_SERVER}/array1_${SHARE_NAME}/${DIR_NAME}
In order to create anything on the NAS without rooting the device, you need to
go into the web admin screen and setup Samba (i.e. Windows) share's. That
creates the directories at the top level of the RAID array (${SHARE_NAME}
above). It also creates the rsync endpoints.
You can use cifs to mount the NAS shares as directories in Linux (apt-get
install cifs-utils in Debian or Ubuntu).
For example (filling in the variables below, of course):
echo //${NAS_DEVICE_IP}/${SHARE_NAME} /home/share/${SHARE_NAME} cifs
file_mode=0644,dir_mode=0755,uid=${YOUR_USER_ID:=1000},gid=${YOUR_GROUP_ID:=100},rw
0 0 /etc/fstab
There's very little you cannot do with the device without rooting it, but
rooting it as described below does add the availablity of SSH, sshfs, and
several other advanced options.
If you want to use backuppc, you need to set it to use rsync as the underlying
protocol (or smb/cifs, either works just fine with the NAS you have).
I don't know a lot about backuppc; perhaps someone else on the list can provide
the details for that.
Happy hacking.

Do I have to root the device to use it as a backup server for my Linux

Buffalo is a U.S. company, and their most recent versions of the Pro Duo

They don't describe much Linux support, but it is running Linux (minimal
kernel with Busybox userland) and uses things like rsync for backup
(although they don't call it rsync in documentation, they call if
BuffaloLink or some such nonsense).
You might want to root it just so you can ssh into the box (ssh is on
the box but disabled from the factory) to play around and possibly setup
some cron jobs to keep things cleaned up, but it's surprisingly capable
as-is.
Rooting it is pretty simple; just run a simple java program called acp
commander that's easily available (
http://buffalo.nas-central.org/wiki/Main_Page, and
http://downloads.buffalo.nas-central.org/TOOLS/ALL_LS_KB_ARM9/ACP_COMMANDER/README)
which can easily start telnet and enable root (I included some brief
instructions below for a clean root).
The very latest versions (the XHL and CHL) of the LinkStation (the ones
that have curvy cases, instead of square) use a new firmware that's even
more stripped-down, so those you have to load an open firmware(recommended,
actually) to make any changes or get command-line access.

Re: RFC - Linux Command Cheatsheet
Most corporate environments are required to disable su entirely due to SOX and PCI requirements to audit every action on the server to a particular user (eliminating user switching as a permissible action). Some companies are even going to the extreme of disabling workaround tricks like sudo bash as well (I think reasonably policy is enough to prevent such usage). It's pretty easy to disable direct root login in RH type servers, and as I noted (and you use in Ubuntu), 'sudo su -' works the same without requiring the system to have an enabled root password.

Re: How to access a server http port 80 with port forwarding behind a router but require a password
Several others have responded, but I wanted to mention a slightly different approach: If you want authentication for remote and not for local; and you want to keep traffic off the HTTP box until it's authenticated for the remote case You might try setting up an HAProxy(http://haproxy.1wt.eu/) on another machine (some spare machine on local net should work fine) and port forward to that. You can then set the listen configuration for port (443, 80, or whichever you end up using) to require authentication (see section 3.4 of the documentation [http://haproxy.1wt.eu/download/1.4/doc/configuration.txt] on userlists) and HAProxy will do the authentication before forwarding the request to the real HTTP server. HAProxy is quite small and lightweight, so you might be able to run it on a router if you have open replacement firmware with a 2.6.32 or later kernel (caveat: I've never tried this and it might take a lot of work), and it has a vast array of other options for custom routing of HTTP and/or TCP requests. For local net you'd just connect directly to the HTTP server or you could have the HAProxy listen separately on the local interface and bypass authentication for local requests. Lots of options, as is usual in the Free/Open world. On 06/30/2011 05:22 PM, leeg...@speedymail.org wrote: Hi, Using Ubuntu 10.04 LTS. I have an intranet server behind a NAT router.

tmpArray=( ${Unix[@]/HP/} )
Unix=(${tmpArray[@]})
at first glance this worked fine, until I realized that now, instead of
'HP-UX' in my array, I now have '-UX'

Following his tutorial, I would need to know the number of the element in
the array I want to delete, but my problem is there may be 10 instances in
the array of 'HP' and I want to delete them all, so I would need to loop
through it over and over until all instances are gone. Also, the elements
inserted into the array are variables and I don't necessarily know the order
of the elements, so I cannot just tell it to delete element X like in his
example. The array is not static anywhere in my script.
So how do I remove something from an array without having to run through
every element in an array and test for whole matches? My array might be 100
elements large, which can take a LONG time to loop through when I am adding
or removing another hundred items to the array. I liked this pattern replace
because it was fast, I don't want to lose my speed now!
Thanks for your help.

Re: ssh question
Based on what you're seeing below, I'd suggest looking at the IP setup on the machines and any router/gateway between the two machines. It looks like something is allowing the ICMP traffic but blocking or loosing the TCP connect for port 22. It might help to run the following commands on each machine to look for inconsistencies or errors: ifconfig -a ip addr list ip neigh ip route Some *possible* causes: 1) More than one machine thinks it has IP 192.168.2.124 and there is an ARP conflict. 2) You have VLAN's setup on the router and the tagging is off or the router isn't passing TCP traffic between the VLAN's. 3) The two machines have subnet masks that make them think they're on different networks (e.g. 255.255.255.0 and 255.255.255.252 or /24 and /30) If the machines are DHCP, have both release and renew their lease (and make sure there's only one DHCP server on the network!). If they're static configured, check /etc/network/interfaces and make sure the subnet mask is the same on both. Dig through your router configuration (I assume you only have one router, if not temporarily remove all but one router) to make sure you don't have VLAN's setup or that they're properly configured Check the ARP tables on the machines and the router (ip neigh at the command line on each machine, router depends on it's interface) to make sure you don't have duplicates and the MAC address matches for each IP address on the different machines example (you may see many more entries than this) (Note that 10.23.124.104 is visible on both and the MAC value matches): Machine 1 10.23.124.104 dev eth0 lladdr 02:49:5a:9e:e2:6c STALE 10.23.124.123 dev eth0 lladdr 03:1d:7f:7f:4d:2d STALE Machine 2 10.23.124.104 dev eth0 lladdr 02:49:5a:9e:e2:6c STALE 10.23.124.125 dev eth0 lladdr 03:1e:4f:73:29:10 STALE There should be only one entry for each IP address in the list on each machine; for a given IP address, all machines should see the same MAC address. Hopefully that helps. Inconsistent network issues like this are always difficult to track down. SNIPSNIPSNIP Again, name/ip resolution is not a problem and is always working correctly.

Re: ssh question
A connection timed out usually occurs due to: 1) The ip address has no host (ping the same IP address, then use telnet to connect to port 22) 2) tcp wrappers is dropping the connection (check /et/hosts.allow and /etc/hosts.deny on lapdog3) 3) the firewall on lapdog3 is dropping the connection (check the firewall configuration on lapdog3 via iptables-save or ufw status) 4) SSHD is not on port 22 or dropping connections (check sshd configuration on lapdog3) On 06/17/2011 02:14 AM, Dazed_75 wrote: Ignore the original question.

Re: Rackspace email DNS
Google Apps free edition started with 100, dropped to 50 pretty quick, and last month they dropped to 10 for the free edition. The corporate Business edition has always been unlimited users at $50/year/user. The paid version has 25G of storage per account which is available across all Google apps. Many companies (even very large ones) find it useful to pay for Google Apps for the following reasons: 1) It costs a typical large company more than $50/year just for email due to a combination of server licenses, client licenses, and (mostly) staff time to maintain the system. 2) Google Apps allows the corporate IT to control use of Google Docs, calendar, photo sharing, etc... Most IT groups have discovered their employees will use it anyway, and if they don't control it then people will do things like accidentally share their spreadsheet with corporate sales figures with the whole world. If the company has a Google Apps account they can default to sharing *within the organization* instead of the whole world. 3) Having email, calendar, and shared documents on Google Apps reduces the need for corporate staff to handle backups and disaster recovery. A simple onsite backup for audit also serves as an offsite backup for D/R because the main systems are somewhere else. 4) The Premium version ($75/user/year) adds powerful corporate audit compliance features that typically cost far more than $25/user/year if hosted in-house. 5) Google Apps has clients for major smartphone systems (esp. Android, naturally), so employees can use their phones to get email, calendar, and view documents (even light editing/collaboration) on whatever smartphone/tablet system they might have. It's not for everyone (with the reduced number of free accounts, there are a lot of small businesses for whom it doesn't make sense), but it's surprising to me how many companies would (and often do) find it to be a strong value. That said, if you really just want pure email that's as low-cost as you can get (while still being fairly reliable), Rackspace is pretty reasonable (although it doesn't work with as many desktop client systems, and doesn't have any phone-based clients I know of). Hopefully that helps. On 06/17/2011 07:54 PM, keith smith wrote: I've heard that rumor elsewhere.� I was told $50/yr for all the email accounts per domain and they were 8gig mail boxes.

Re: Looking for Ideas to facilitate group communication on the road
There are other issues with GV too; the biggest being that a number cannot be assigned as a mobile number on more than one account; so if anyone in the group uses GV, they won't want to have their number disconnected from their GV just to use your setup. Also, you cannot have GV forward to another GV number. I think you've hit upon the closest solution without paying for a business-oriented spam/marketing bulk SMS system. Have GV forward to an email account; parse that out to pull a tag (containing 0ga0/0gb0 usually works and it's fast(ish) to type on A9 keypads) and forward to a list of SMS email endpoints based on the tag. It might be good to also have unrecognized SMS forwarded to you so you can reroute when people goof up. There is an alternative if you don't mind locking an older phone to a computer back home for the duration of your trip (http://smslink.sourceforge.net/). That system allows you to have an sms received on the attached phone forwarded to a customized email output, and you could, relatively easily, add support for sending back out via sms. It's a bit rough and not the most reliable, but it seems to work. On 06/06/2011 05:02 PM, Mark Phillips wrote: Some feedback on the google voice idea A. I set up a new phone number and tried to add other phone numbers for forwarded texting. The only hitch is that the new phone number requires a verification code be sent from an sms on that phone. It makes sense, or someone would use google voice to spam everyone. It looks like I get a different verification code every time I add a new phone number. It does not seem practical to have all the club members get a verification code and respond to a text message from google voice. B. I don't see a way for someone to send a text to a smaller group than everyone on the list. I have two teams, so the 12U folks don't want to see the 14U texts, and vice versa. But the google voice number is a great idea. I can give out that number and say - use this to send sms to everyone. I was thinking of google voice forwarding the sms to an email account, and then have a script of some kind parse the email and send the message back to everyone's cell phone using the email to sms gateways that the carriers provide. I could then have a tag in the sms to:x where could be one person, and the email parser could find it and send the messages appropriately. Adds a delay, but I don't see another solution. To restate the problem: How do I provide a group of people a way to send/reply to sms messages to anyone in the group, or a subset of the group, or one person without relying on any special cell phone capability (such as group sms or email)?

Not quite what you're looking for, but timeoutd is a tool for limiting time in sessions, including idle time.

Re: How to set Calibre directory? Solved
The ugly directory was actually, most likely, for a single book. Calibre defaults to using your home directory as the library directory and uses a fairly complex, but Windows-friendly, filename and directory structure below that. It's a bad interface decision, but Calibre has absolutely horrible UI structure and design, so that's not surprising. I like the *capability* of Calibre, I just wish someone would take the same capabilities and produce a decent UI for it. On 05/15/2011 11:08 AM, j...@actionline.com wrote: Thanks Joseph. I finally found that calibre does allow one to create new (actually multiple) library/directories; and, in fact, it allows creating one with a switch option to automatically move all books into that newly created one. So, I was able to create one with everything moved into that new one and then just delete the one that calibre had automatically created initially with that confounded file/directory name with caps and spaces in the name. Why would they have done that? Anyway, the problem is now solved. Thanks again. The Library button (probably reads something like 35 books) controls this.

For advanced administrative options (particularly for complex requirements and/or large numbers of virtual machines on multiple servers), the VMWare enterprise tools are generally needed, and those get very costly. The primary advantage of VirtualBox is that it is both free-as-in-beer and free-as-in-freedom (the open source edition, virtualbox-ose), and the tools to manage it are included. VirtualBox is great for running a few occasional VM's on a well-equipped home computer.

Re: Why these mostly empty hidden files?
Most of that is cache data (e.g. swf's code fragments, etc...). They do store Flash cookies in .macromedia and/or .adobe, but the directories you see are their cache structure. They've gotten tricky lately in that they now often use a deleted file for data cache (open a file, unlink it, continue writing; the system has no issue with that but it's harder to read in Linux and impossible in Mac or Windows), which makes their cache dirs look a lot less full than they actually are. I just wipe out ~/.macromedia and ~/.adobe anytime I have no choice but to use flash to view something; makes life easier.

Re: Chosing a programming language for today and the next 10 years
Lots here, Hopefully this will help. 1) Windows is a terrible bet. It's already having trouble in the market on multiple fronts; it doesn't scale up to servers (well), it doesn't scale down to mobile devices, and it won't likely work well with the transition to ARM architectures and a more diverse hardware ecosystem. 2) Apple will never dominate anything (in computing devices) for long. They're too tied to the closed-control-everything walled-garden approach, and most people don't really want a device that's completely closed (witness the surprising popularity of jailbreaking iPhones) outside of simple single-purpose consumer-electronics devices (like an MP3 player, and even there Apple is less dominant than they'd like you to believe). 3) Don't choose a single language and expect to use that for 10 years; it's extremely unlikely any given language or platform will hold sway that long. 4) Apple IOS *is* OSX on phones. It's the only version of OSX that will ever run on a phone. That said: Java is a great platform to learn, particularly for mobile; consider building an Android app to learn with (Android apps are Java with some slight modifications and extra API's). The Android SDK runs in Linux and provides an actual system emulator so if your app runs in emulation it will almost certainly run on real devices (unless you do something really weird). If you also want to try some web development look at building a straight-up servlet app with Tomcat6 (avoid Spring and J2EE; the first has jumped the shark and the second is very complex). Servlet programming is relatively easy to learn, and it's immensely powerful. Almost all examples of JSP programming follow the broken ASP model, which is almost the worst possible way to architect a web application. You might also look at the Google Web Toolkit, which allows you to use Java to develop the AJAX frontend as well. C and C++ are strong languages, but not terribly well suited to mobile apps unless you have a lot of experience and need the absolute maximum performance on a phone. If you are interested in those languages learn the QT toolkit as well, as that will help you create C++ applications that are cross-platform without a lot of *very* difficult work. Understand that it's generally expected that everything you write for the first 5-10 years using C++ will be horrible, just because C++ is more complex and powerful than generally recognized. It might be useful to look into Python, Scala, and Javascript as additional options for a, currently in-demand, strong niche language that will buy time to build a broader skillset. If you really want to develop for iPhone, then buy a Mac desktop or laptop and develop using Objective-C, since that's more-or-less required to develop a native iPhone app. For most cases, the best place to develop a new desktop application is Linux; develop using Java, C++ with QT, or Python with wxWidgets and you'll be able to run it on Windows and Mac as well, but developing on Linux will encourage cleaner code and provide a smoother software development process.

I was thinking of C++ because no matter where the market goes C will more than likely be useful on Windows, MAC, and Linux. Then there is Java. The write once run everywhere language. Nice thing about Java is I can build web apps with it as well. As phones become smarter, I suspect there will be some real need there also. Then I also hear the rumor of OSX running on phones. Nice!

Re: double-extensions in apache?
Apache and other web servers are required to send the MIME type of any data in a response. There's really no such thing as a file in HTTP, only data streams and MIME boundaries, so that MIME type is pretty important. How else, in a general and cross-platform way, are the web servers to figure that out other than looking at the file extension? Also, the cascading file type approach is there because website builders (mostly Microsoft's frontpage abomination and similar garbage) have been known to throw all kinds of extra file extensions on content that's imported (like taking image.png and saving it as image.png.bmp). Sometimes there is filesystem metadata and sometimes not, but none of that is cross-platform and even when it's available it isn't always populated. Webservers may use it if it's present, but they always have to fallback to extension matching. It's not ideal, but it's what the developers of the Apache webserver have to do to make it work for a wide audience (one of the downsides of being, by a huge margin, the most widely used web server on the net) There are tools to check your site and ensure everything is clean with extensions, metadata, etc... Those should be used by everyone developing a website. There are also settings to disable content-type-determination on uploads, and those should ALWAYS be enabled. It's OK to guess the content type of a file in the filesystem, but an HTTP PUT request is supposed to *tell* you the mime type, and if it doesn't then the sender simply cannot be trusted to put content to your site. Just my thoughts on the matter. ==Joseph++ On 03/20/2011 12:21 AM, der.hans wrote: moin moin, When web servers such as Apache decide how to process a URL request, they use the file extension.

Re: Programing help read USB Joystick using gcc
Sounds like what you need to do is very similar to writing a custom driver for your joystick in an embedded environment. You'll probably need to do something similar to the following: 1) A library for usb interface in your environment a) libusb provides a low-level interface to USB data for Linux, but it requires the Linux kernel to provide the host controller drivers. b) If you aren't developing under Linux, then check with your SBC vendor about drivers for their USB host controller. 2) If your environment doesn't already have a driver for your joystick, you need to find out what the joystick sends for commands and data; there are two common ways of doing this a) Pull up a Linux driver for the joystick (if one exists) and use that code to determine the USB command and data structures (easier) b) use a USB snoop device to reverse-engineer the interface for your joystick (much harder) 3) Write the code needed to interface with the joystick a) If you do not already have a driver available, write a driver for your environment, and connect that to your ROV control code. b) Write code using libusb that interfaces with your joystick using an existing Linux driver. This page is a good starting point for developing any USB interface code, whether in Linux or otherwise: http://www.linux-usb.org/ Hopefully that helps.

Re: Using KDE but want something different
XFCE, LXDE, or JWM fit what you describe. Gnome is somewhat close for now, but it has been getting away from the simple desktop approach for a while, and the latest (3.0) is very Mac-like and far less customizable than KDE. You might also look at WindowMaker (ultra clean/light, but no taskbar) or the Enlightenment Desktop (very nice graphics, but still cleaner than KDE and more customizable than Gnome) mz wrote: I'm looking for a replacement desktop.

Re: Ubuntu Desktop dns binding help
I would assume that he's talking about broad testing within a local network, rather than testing against localhost directly. I often do this because I can insert firewalls, routers, etc... as/where desired to emulate probable scenarios. It's particularly helpful to emulate 4in6 or 6in4 connections when using external providers that do not provide sufficient IPv6 support. It's just easier to create a hostfile entry on the test client(s) than to create or modify public DNS (sometimes that's not even possible). This is particularly true when the service you're testing is already live and you need to black-box test a component of an interconnected SOA system.

If there are no firewalls or other local security, you will get the same result testing against localhost as you would your local file system. So therefore there is no need for DNS at all.

Re: SMTP proxy for masking credit card numbers
This is a somewhat unusual requirement, so I couldn't find a quick out-of-the-box solution, but there is a way to do this. The general-purpose approach is to add a filter on the mail processing path. There are many listed here (https://www.milter.org/) that work with sendmail, postfix, and similar common MTA's. You will probably need to write a regex matcher or a small python script (using pymilter http://pymilter.sf.net/) to match anything that looks like a credit card and replace the digits with 'x' or similar. Keep in mind this will probably be a bit fuzzy, as there are many things that look enough like a credit card number to result in some mistaken filtering.

Same error - could not connect to T-Mobile network. I then tried to make a WiFi call at Starbucks, and it worked! It also worked at Barnes and Noble after I agreed to the free Internet terms and services (didn't work before then). I googled for issues with WiFi calls with this phone, and found a lot of them. Sometimes it works and sometimes it doesn't. The error message that pops up says the phone cannot connect to the T-Mobile network. T-Mobile is aware of the issue, but does not have a fix or ETA for one. One posting had this to say about the WiFi calling. The WiFi Calling app is Kineto's WiFi Calling app branded for T-Mobile. The WiFi Calling app is an implementation of 3GPP GAN, which allows something on the Internet to get into a cellular network and do stuff (in this case, make and receive calls).If you care to pull up the most recent version of the spec, linked above, you'll find that registering (ie, logging into home base) involves these steps (get a glass
Re: runaway process udisks-daemon and how to resolve?
udisks_daemon is part of DBUS and UDEV. It's the DBUS device manager for the disks on the machine. I have also had issues with DBUS and UDEV elements locking up the system from time-to-time. The only solution I've found so far is to restart the machine on occasion, just like I used to have to do with Windows back when I ran that mess. I have only found this instability in desktop environments like Gnome and KDE; I have no similar stability issues with the servers I run. It seems that the current versions of Gnome and KDE have uncovered issues in the DBUS and UDEV subsystems with their increasing heavy (ab)use of DBUS. You might also try the XFCE desktop and see if that works for you; I believe ORCA still works on XFCE, and its less complex use of DBUS might allow the system to be more stable.

I keep having a random occurrence of udisks-daemon causing my powerbook G3 to start locking up.

Re: rsync help the gramma
You're pretty close to ideal there. I use rsync -avEHh --delete-after --progress $SOURCE $DESTINATION Generally no need to sudo for your own homedir, and -z is really only useful for network copying (it compresses in-transit, not on disk). That will only copy over changes between the source and destination, and will remove anything in destination that's no longer in source. Make sure the external drive is formatted EXT3 or XFS so you can preserve things like access controls and ownership. When you look at the final output of the command, there's usually a ratio listed. That's the amount that could be copied vs. the amount actually copied. If that's much larger than 1, then you're only copying changes. ==Joseph++ betty wrote: I have an ext hdd that i copy my stuff to every few months.

Re: Best Way to Multi-Boot?
I don't have quite the same situation, but I do need fairly large storage shared between multiple systems. I use a nice little 2TB NAS box for the storage, since then it's on a separate system (so one power surge doesn't take out everything), I can use cron to schedule rsync backups, and I can do regular backups of that to a 2TB USB drive (fairly cheap) using dd (embedded distro only has rsync and dd). Using a NAS also makes it a little bit easier to add storage; most will allow expansion with USB drives (slow but effective), and it's not unrealistic to get devices with 4 bays and eSATA expansion (have you seen the 15-bay eSATA expansion boxes?) that allow serious storage growth (from 8TB up to 30TB or so) if needed. I have 3 different Linux distributions in use (on 3 different machines, however), not counting the embedded Linux in devices (NAS, routers, etc...). I switched to using VirtualBox for experimenting with new distros a few years ago to get out of the multi-boot headaches. I, too, had issues with Ubuntu 10.10 (and 10.04), so I switched to Kubuntu at work (slightly more stable) for now, and have been evaluating a few different rolling distros because I don't see Ubuntu acting like a good community member anymore. Ubuntu seems to be heading down the road of becoming a proprietary Linux-based O/S with their own value-added garbage (e.g. Ubuntu One) rather than a fully open GNU/Linux distribution. I understand them wanting to find a commercial model that works, but I suspect the road they're on isn't it. The NAS is a Buffalo LinkStation, by the way, I've been fairly impressed with the device and it's Linux internally (I had to root it to get ssh and rsync, but that turned out to be trivial to do), only thing I don't like is it's CIFS/Samba-only and doesn't support NFS or iSCSI. I've done some poking around in Chromium O/S, and you're right; that belongs on devel. Mike Hoy wrote: I need to run Windows and Linux. It has been this way for years.

Re: Arm multicore multinode servers?
These are part of an interesting (IMO) trend toward using less traditional system architectures, in this case using much less powerful ARM chips (an ARM does a lot less per clock than an equivalent x86_64 CPU) in large numbers to provide basic (i.e. low per-page computation) web services, to more effectively fill a target niche. Website serving (in most cases) is exactly the type of low-CPU high-I/O task that's perfectly suited to very large numbers of weak CPU cores. Each request can easily run on a different core, but pushing a page (even one generated from *simple* JSP/ASP/PHP) takes very little CPU. Running a lot more cores helps, but running expensive fast cores does not (this is mitigated somewhat by event-driven servers like NginX, but more cores is still better). You will need a ton of network and disk I/O, but things like tcp-splice, tcp-offload, a copy-free TCP stack, memcached, membase, FusionIO cards, etc... are making that a very reasonable proposition for a Linux system like these. As a side note, that's always been the advantage of Mainframes (which are still used for a LOT of stuff) for similar types of line-of-business tasks (like transaction processing); they don't have a lot of raw CPU, but they can push bits at rates an x86 couldn't dream of matching. The advantage of these ARM based systems over a distributed or mainframe-type system is that they're a few orders of magnitude less expensive, ideally suited to web serving, and use vastly less space, power, and cooling than a commodity system with the same page-per-second capacity. I would never even think of using one for something like a database server, but as the web front-end they're pretty close to ideal. GPU computing (e.g. CUDA or OpenCL) is another example of alternative, more targeted, architecture; this time for extremely parallel high-CPU/low-I/O tasks (the opposite of what these ARM boxes are suited to). I predict that we will see a continuing diversification of system types as different types of tasks and new computing techniques drive a need for a wider variety of non-traditional architectures. I read an interesting article on the IEEE website today about using memristors as a similarly novel computing architecture to accomplish tasks currently solved by neural processing algorithms because a memristor array acts, in some ways, like a neural array. I should note here that these ARM systems won't replace x86 systems, just as x86 hasn't replaced mainframes. These new architectures will expand the diversity of systems in use; existing systems will still be used where they make sense, and these new systems will take over in niches where they significantly outperform existing approaches. Stephen wrote: http://www.theregister.co.uk/2010/11/23/zt_systems_arm_server/ so what is plugs thought on this. Aside from pre-shipping with Linux (ubuntu) i can see how low power server nodes for those itty bitty nibble tasks can make sense, but they are looking to push a ton of little cores soon. signature.asc Description: OpenPGP digital signature --- PLUG-discuss mailing list - PLUG-discuss@lists.plug.phoenix.az.us To subscribe, unsubscribe, or to change your mail settings: http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss
Re: Building my own package
There are a lot of ways to do this, from dead-simple to very complex. It
depends a lot on how much of the functionality of dpkg your package needs.
I roll deb packages for a lot of projects using Maven2 and the jdeb plugin; for
any project using Maven2 to build, it's dead simple.
For relatively basic projects, the following process works OK:
1) create a subdirectory build to build from.
2) create the directories where your files need to go on the target system,
pretend the build subdirectory from (1) is /.
3) Create another subdirectory next to the first, call it control
4) Create a file in control called control.
5) Edit the control file according to
http://www.debian.org/doc/maint-guide/ch-dreq.en.html#s-control
6) in the build subdirectory find * -type f -exec md5sum '{}' \;
../control/md5sums
7) in the control directory, tar zcf ../control.tar.gz .
8) In the build subdirectory, tar zcf ../data.tar.gz .
9) create a file debian-binary in the parent directory with the contents
2.0\n where \n is a newline.
10) in the parent directory, ar q some-package.deb debian-binary control.tar.gz
data.tar.gz
That should do it.
For more complicated setups,
http://www.debian.org/doc/maint-guide/ch-dreq.en.html is the definitive
starting point.

Re: OT: WiFi hardware question
Normally, an Access Point is intended as the base station part of a Wi-Fi network. It is possible, sometimes, to use one as a wireless bridge (which is what you're describing in connecting it to the ethernet port), but I'd be very leery of using such a low-cost unit in that role; it's not entirely uncommon to see low-end units like that function very poorly or not-at-all. As for antenna size, a 2.4GHz antenna is generally going to be most efficient at 1/4 it's wavelength of 12.5cm. Most small devices have an antenna of about that size (around 1.2 inches), and there's little or no advantage to using anything larger. The larger antennae on some access points and bridges are usually dipole (2 antennae at 3.125cm each in opposition around a common centroid) and aren't actually any better at receiving signal, but they feed into a much higher gain amplifier stage using a differential amplifier which has better signal-to-noise ratios at the cost of using more power (and requiring a dipole antenna). Wireless N uses VOFDM reception which drops dipole amplification and, instead, uses it's antennae to, receive more power from the original signal via multipath amplification (basically using weaker signals from other angles to amplify the strongest core signal). You might be better off getting a newer Wireless N USB dongle with 2 (or more) internal antennae for multipath diversity (which usually provides better signal in home environments than dipole amplification) rather than tying the machine to a fixed bridge of uncertain quality. I hope that helps. ==Joseph++ Steven wrote: Okay, this one seems like a no-brainer question to me but I haven't dealt with one before. A wireless access point like this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16833180035 should get better reception with that antenna than one of those little stubby USB adapters like this: http://www.newegg.com/Product/Product.aspx?Item=N82E16833127272 My sister's computer is hooking into our wireless using a USB wireless adapter about the size of that second link (although it's too old to still show up on Newegg, I'm just pointing to something similar in size), and it's never had great reception, but lately it's been very flaky. Looking over things I realized those access points start in the same price range as the USB adapters while having those nice antennas that are longer than the USB sticks are even including the USB plug. That said, I've never actually used an access point, it's always either been a built in laptop adapter, a PCMCIA adapter (which got a lousy signal going through two fewer walls than are between the wireless router and my sister's computer), or one of those USB wireless adapter sticks. If I'm catching how it works correctly her computer should simply see it as a plain old connection over the build in Ethernet port, correct? --- PLUG-discuss mailing list - PLUG-discuss@lists.plug.phoenix.az.us To subscribe, unsubscribe, or to change your mail settings: http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss signature.asc Description: OpenPGP digital signature --- PLUG-discuss mailing list - PLUG-discuss@lists.plug.phoenix.az.us To subscribe, unsubscribe, or to change your mail settings: http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss
Re: libreoffice, good news or bad news
Thanks to the copyright assignment requirement for OO.o, Oracle does own all OO.o copyrights at this point. The copyright statement will change if and when new contributions outside of that copyright assignment become significant. Then it will read Oracle and others, because Oracle will still own a lot of copyrights (unless they sell them) in the codebase for a long time to come. Thank goodness OO.o was relicensed, before the Oracle takeover, to LGPLv3; the previous CDDL licensing would have prevented this fork entirely. From the way I read the materials it seems copyright assignment will still be part of the project, but more along the lines of the FSF assignment, which is a lot easier to swallow than the Sun (now Oracle) model. ==Joseph++ P.S.

Re: Need a mail app for LARGE volumes of mail...
This sounds more like a situation where you just don't trust GMail to keep your older emails, but you still really need cloud access to the current/recent email. What you might find most useful is a hybrid setup. Use a local store (fetchmail-into-mbox, thunderbird on POP, IMAP/Backup, etc...) on a system at home that you don't mind running as a server and have that download everything, read-only, from GMail and keep it forever in a small/light IMAP server like qmail-toaster as Eric Shubert suggests. Set the gmail to archive and remove (might need to enable a lab for this) anything over some reasonable age (perhaps 1 year?) so it serves as a cloud-based cache for recent email without all the old stuff. Use a caching IMAP client on the laptop to access gmail while on the road (gmail with offline enabled, Thunderbird in IMAP mode with local storage enabled, etc...). Have another client at home to read from your archive server for older messages that won't be in your GMail any more. There are a lot of variations on that structure.

So one process runs and is piped into a second process. $ process1 | process2 Is there a way I can pipe process1 into process3 (and still pipe into precess2) ? So process1 runs and process2 and process3 run in parallel both feed by process1. So like test.txt file w/content: a b c --- then $ cat test.txt | grep a $ a $ cat test.txt | grep c $ c I want cat test.text to feed both greps at the same time and maybe get output like: $ac I tried the tee command w/no luck. Is there a way to do this on one line at one time? Thanks. using Ubuntu w/Bash.

Re: OT : Need to determine what the going rate is for a junior programmer
salary.com There's a quick ballpark value you can get for free, and you can pay a moderate fee ($99) to get detailed information including W4/1099 breakdowns and secondary factors for a single job. For your case select the salary wizard on the front page, enter the job title (Programmer or Software Engineer) and a ZIP code, when the results list comes up check the description until you find one that matches your experience expectations, then choose the For Employers results link. You'll get ballpark general data right up front, and a link to buy the full detailed report (which asks a lot more questions to match your job requirements better) if it looks like you have the right result (or you can back up and try another title if you don't think you have the right job title). I've been using it for years to benchmark the general market for various positions. keith smith wrote: Hi, I need to find a helper and need to determine what the going rate is for a junior programmer with a year or two of experience, maybe more.� He or she would need all the normal skills, PHP, MySql, CSS, JavaScript, XHTML, some AJAX exposure using a common library like MooTools or jQuery.� Extras that would be a plus : Drupal, payment gatway, some LAMP skills.

It is a great gig working with a very successful virtual company which does all it's business online.
