Re: Will HTML5 eventually sub for Java?
So with this background, I don't think we will ever see that HTML5 or any later standards will replace Java at all. HTML may take advantage of Java Applets when the HTML + JavaScript is not powerful enough to solve your task. To be fair, I can't really think of a Java application that couldn't be done by new elements in the HTML5 specifications. For instance, video conferencing, 3D applications, full screen, VOIP... Probably the only thing I can think of that I've actually needed Java for recently was a cisco VPN software installer, which could probably have also been done in javascript+html. It used to be that Web developers' hands were tied with regards to building web applications, but newer standards have created some really interesting possibilities :) -Chris

Re: No more flash updates?
Another option is to install Google Chrome and get more recent versions of Flash provided for you by Google. As far as I know, Google made an agreement with Adobe to allow Google to support Flash on linux - I'm willing to be corrected on this if someone has a source that negates this premise. But yes, I agree that Flash is a hell hole of security flaws and problems. I think most sites are starting to migrate to HTML5, including some online game companies - hopefully we won't need Flash in the future. -Chris On 2013-01-14, at 10:32 AM, Todd And Margo Chester toddandma...@gmail.com wrote: Hi All, Over on http://get.adobe.com/flashplayer/?promoid=JZEFT it states: NOTE: Adobe Flash Player 11.2 will be the last version to target Linux as a supported platform.

Re: Suggestions wanted for reducing CPU load
Hello! Which version of Firefox are you using? I newer version might help reduce CPU/Mem load. You might also try Google Chrome, there's a linux installer available - I've found chrome to be slightly better at memory management and a bit speedier... (Although new versions of firefox may negate that advantage) Generally, Flash does consume an huge amount of resources, so if it's required for you to use it you might just have to grin and bear it - you might also consider talking to the people who require flash to see if an alternative solution is available - most functionality can be replicated with HTML5 now. Make sure your version of flash is 64 bit as well. There might also be something I've missed, in which case someone else on this list should feel free to chime in. -Chris On 2012-11-13, at 12:38 PM, Yasha Karant ykar...@csusb.edu wrote: Right now, my quad core SL 6x X86-64 workstation is not responding very well; a quick look at top reveals: Tasks: 181 total, 2 running, 178 sleeping, 0 stopped, 1 zombie Cpu(s): 41.1%us, 7.2%sy, 0.0%ni, 51.3%id, 0.4%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 8196468k total, 8002116k used, 194352k free, 9344k buffers Swap: 2048252k total, 1753152k used, 295100k free, 543572k cached PID USER PR NI VIRT RES SHR S %CPU %MEMTIME+ COMMAND 3417 ykarant 20 0 1679m 738m 8752 S 122.2 9.2 9239:30 plugin-containe 3342 ykarant 20 0 2995m 2.2g 18m R 94.9 28.2 8309:43 firefox 2051 root 20 0 4448m 3.1g 9440 S 1.8 39.6 443:40.39 Xorg 2793 ykarant9 -11 559m 3028 1860 S 1.8 0.0 20:04.64 pulseaudio 3113 ykarant 20 0 321m 6904 5292 S 1.8 0.1 211:10.01 gkrellm 18994 root 20 0 000 S 1.8 0.0 0:00.05 kworker/2:3 19318 ykarant 20 0 15136 1140 812 R 1.8 0.0 0:00.04 top 31800 ykarant 20 0 1247m 58m 952 S 1.8 0.7 68:45.24 java 1 root 20 0 19448 872 660 S 0.0 0.0 0:04.12 init 2 root 20 0 000 S 0.0 0.0 0:01.81 kthreadd 3 root 20 0 000 S 0.0 0.0 0:06.58 ksoftirqd/0 5 root 20 0 000 S 0.0 0.0 0:00.03 kworker/u:0 6 root RT 0 000 S 0.0 0.0 0:00.00 migration/0 7 root RT 0 000 S 0.0 0.0 0:00.26 watchdog/0 8 root RT 0 000 S 0.0 0.0 0:00.00 migration/1 10 root 20 0 000 S 0.0 0.0 0:09.72 ksoftirqd/1 12 root RT 0 000 S 0.0 0.0 0:00.44 watchdog/1 Note that from above: 3417 ykarant 20 0 1679m 738m 8752 S 122.2 9.2 9239:30 plugin-containe 3342 ykarant 20 0 2995m 2.2g 18m R 94.9 28.2 8309:43 firefox My institution requires the use of Adobe flash (as well as java), and thus it seems that plugin-container is being used.

Re: G Drive
Maybe we were given a stunted version to test, but on Google's own OS and Mac OSX we had to deliberately drag drop each file that we wanted saved to the local computer for access offline. I thought I would just verify that, on my Mac OS X (10.7.4) Core 2 Duo Macbook Pro with Google drive installed, I can see the data in the google drive when I am disconnected from the network. I have turned off wireless, unplugged the network, and verified that no network connections exist, and still I can access data in the google drive folder :) So unless I understand you incorrectly, they did probably give you a stunted or buggy version.

Re: G Drive
Thought I would chime in here. Also, I didn't mention this because I thought it was obvious, but you don't exactly mount the Google Drive. Its basically like a feature-deprived version of Dropbox with an even worse privacy policy that only integrates with Google products. It is absolutely not available offline -- and actual syncing has to be a deliberate choice, every time, so actually saving to a local drive you own for real is not automatic or even reasonably hassle-free. So this sort of sucks. If you don't have a google drive client, this is correct. This means all linux, currently, but google drive on Mac and Windows appears to be almost exactly like dropbox, save for any differences in licensing issues - sync looks to me to be automatic on the mac, and is as painless as dropbox. If you've got no experience whatever with this sort of thing these are probably the points you are curious about from a consumer's point of view. Dropbox works fantastically with Scientific Linux, and it's been around for a while now. There's also sparkleshare, which is uses git to coordinate between your own computers. Dunno how well that works for people, but it's open source and doesn't look like it requires a central server ala google drive or dropbox. Sparkleshare: http://sparkleshare.org/ Dropbox: https://www.dropbox.com/home Indeed, you cannot mount a google drive like a network drive (i.e. no mount -t googledrive), and I suspect once a linux client is released it will be similar in scope and methodology to dropbox, as the mac and windows clients seem to be. -Chris
Re: Whitelisting websites
It isn't clear if you are looking to provide your user with some voluntary self-filtering or if your user wants to impose filtering on others. Ah, apologies to everyone! (I was curious about the political statement). It is indeed *self* inflicted. The user is having trouble getting his work done and finds his own behaviour online detrimental to his work process. People gave you ideas about the latter. For the former there are various browser plugins that your user can install to self-manage their own filtering. For example Chrome's Personal Blocklist extension. Although the emphasis there looks to be default-allow rather than default-deny. I figured if the user has issues to the point of requesting that I whitelist websites he may not find a plugin for browsers useful (i.e. easy to circumvent), however, I did encounter these options as well in my google searches so I will suggest this as an option. Thanks everyone! -Chris

Adobe Reader 9 + 64 bit SL6...?
Hello all, I've been trying to get Adobe Reader 9 working on a machine I take care of, and it won't run when not run by root. I have installed the adobe-release repo, and installed adobe reader with yum install AdobeReader_enu Users log into this machine and their home directory is mounted over NFS. The machine is 64 bit Scientific Linux release 6.0 (Carbon) $ yum info AdobeReader_enu Loaded plugins: refresh-packagekit Available Packages Name : AdobeReader_enu Arch : i486 Version: 9.4.6 Release: 1 Size : 57 M Repo : adobe-linux-i386 Summary: Adobe Reader, an application to easily view, print and collaborate on PDF files. URL: http://www.adobe.com License: Commercial Description: Adobe Reader software is the global standard for electronic document sharing. It is the only PDF file viewer that can open and interact with all PDF documents. Use Adobe Reader to view, search, : digitally sign, verify, print, and collaborate on Adobe PDF files. (this the yum info is after having uninstalled the application, which is why it shows the repo as adobe-linux-i386 and not installed When I run acroread as root, Adobe Reader starts up fine. When I run acroread as any other user (all other users use an NFS mounted home directory) Reader won't start. Doing an strace shows that the reader hits a segfault when run as any user other than root - and I can't tell why it's segfaulting. The strace doesn't actually tell me anything interesting beyond that, other than the fact that reader stats the local directory several times. I've managed to coax a crash log from adobe reader, but I get some simple list that doesn't tell me much of anything: == /usr/bin/acroread [0x8508e25] [@0x8048000] (__kernel_sigreturn+0x0) [0x110400] [@0x11] /usr/bin/acroread [0x850c0ac] [@0x8048000] /usr/bin/acroread(main+0x87) [0x85705c5] [@0x8048000] /lib/libc.so.6(__libc_start_main+0xe6) [0x3e07ce6] [@0x3df1000] == Looking at the acroread command itself, it appears to be a complex script which then bootloads a bunch of library files and then loads reader from another directory.

If you are fine with using i686 system, then you usually don't need to do anything on such hardware upgrade - the only typical minor problem can be with ide controller detection (driver for new controller is not present in old initrd). It can be fixed in various ways - for example, I prefer booting rescue mode, going to console, mounting old system, chrooting into it and running mkinitrd or reinstalling kernel. If you want to move to x86-64, then you have to reinstall system, as in real reinstall, not upgrade; depending on your partition scheme /home might be preserved, or you might need full backup, clean reinstall and then restore of parts you need. Or, if your VG has enough free space, you can just create new LVs during installation, install there then copy data you need from old LVs.

Re: MySQL Performance and Replication??
Apologies, forgot to post to the list :P For optimisation: I've found that going over the SQL queries and attempting to pare them down a bit helps a lot. Use EXPLAIN and become familiar with it's syntax, it will tell you how it's doing the queries and you can then optimize. (for instance, there may be JOIN clause that makes MySQL look through all rows instead of an index or something like that) If you find that it's doing a lookup on a column frequently, try giving that an index. Also, depending upon what sort of queries you are doing, you may find better performance by switching the backend engine of the specific table. I would also recommend checking out memcached, especially if you are only reading information frequently, and you've got a lot of memory on your server - it will cache more common results in memory. I'm sure there are some other things I am missing, but I've found that these are the better options. (especially revisiting your heavy queries) As for replication, I've always left that to the sysadmins when I was a developer. :P -Chris On 2011-10-28, at 12:46 PM, Phong Nguyen wrote: There's the basic hardware options - more spindles (in RAID-10) or supercapacitor-backed SSDs, etc. Check your queries and see if you can optimize them to return less data.

I would assume that TUV only packages the software, not modifies it - and they would definitely have more expertise in their software than the SL mailing list folks :) LibreOffice mailing lists: http://www.libreoffice.org/get-help/mailing-lists/ -Chris On 2011-10-07, at 1:17 PM, Larry Linder wrote: Kids have added a twinkey box around the last used cell - does not follow active cell or #value or anything relevant.

Re: How to install VLC player/Chrome/VirtualBox on Scientific-Linux 6.1?
VLC is in rpmforge. If you install the rpmforge repo: yum install rpmforge--release You should be able to install vlc: yum --enablerepo=rpmforge install vlc There is also an adobe repository: yum install adobe-release then install the flash plugin: yum install flash-plugin For virtualbox, you will probably just have to install via their packaged RPM: https://www.virtualbox.org/wiki/Linux_Downloads they have one specific to EL 6: Red Hat Enterprise Linux 6 (RHEL6) / Oracle Linux 6 (OL6) As for a paint alternative, there's GIMP available in the SL base repos, just: yum install gimp. Apparently you can get chrome running on EL6 by following this tutorial: http://blog.ask4itsolutions.com/2011/03/20/howto-installing-google-chrome-on-rhel-6-red-hat-enterprise-linux-6-32bit-64bi/ I haven't yet tried that though. -Chris On 2011-09-30, at 9:18 AM, lancebaynes87 wrote: Using other distribution's repositories is a bad idea, because ex.: Fedora doesn't has 6 years support of a given version of the OS. What is the best-practise for Scientific-Linux? What are the to-do's after a Minimal Desktop install? So the real Question: How can I install a fresh version of these apps on Scientific-Linux 6.1/64bit?: * VLC player (it's not in the default repositories and all I can find is an outdated VLC in rpmforge) * Chromium/Google Chrome? * Flash Player * VirtualBox * microsoft paint alternative :D http://unix.stackexchange.com/questions/21785/to-dos-after-installing-scientific-linux-6-1-for-desktop-purposes/ Or it is advised to use another media player other then VLC? there are many AVI/WMV/MP4/FLV/etc. videos with many codecs. VLC has many codecs (built-in?) that's why we need it. but fixme if there is a better media player for Scientific-Linux.
Upgrading from 32bit to 64bit
Hello,
What is the procedure for upgrading from 32bit to 64bit? I did an upgrade with
the CD but now I have authentication failing because it's looking for the 64bit
versions of nss_ldap and can't find them - so I think I may have missed a step.

Re: Upgrading from 32bit to 64bit
Hello all,
I may have solved this:
I removed /etc/rpm/platform:
rm /etc/rpm/platform
confirmed that rpm recognized that I had x86_64 arch:
rpm -E '%{_arch}'
x86_64
and then reinstalled python:
yum install python.x86_64
After doing a couple more installs of the x86_64 bit versions of some pam and
nss modules I was able to get back to working order. There are probably some
other things that may need to be fixed, but yum update isn't showing a whole
bunch of i386 packages anymore :)
For the record, I did an upgrade with a CD from i386 SL 5.4 to SL 5.7 x86_64.
Upon rebooting, yum would insist I had 386 arch, and the authentication method
I had was failing (it was looking for 64 bit versions of the pam modules and
nss modules).

Re: .xps files on SL5
Apologies for the double post, forgot to post to the listserv (maybe other people can get some info out of this too): You might try using kpdf... apparently okular is based upon that. That's located in the kdegraphics package. However, it looks like okular is specifically the one that reads xps. There is also ghostxps which can apparently convert from xps to pdf format.

It's like it was not able to load a font table so the screens, dialogs, buttons, are all blank. The install works. I'm not particularly bothered by it but thought you might want to know. I've done several SL 6.1 kickstart installs in the last week, but I never saw anything wrong, all info was displayed as usual. Having said that, when installing with kickstart I don't have dialogs, but buttons and other text I see during the install all look fine. -- --Jos Vos j...@xos.nl --X/OS Experts in Open Systems BV | Phone: +31 20 6938364 --Amsterdam, The Netherlands| Fax: +31 20 6948204 This may be a long shot, but there may be something wrong with your video card. I've had garbled text on a terminal and it was due to my video card dying for some reason. Christopher Tooley ctoo...@uvic.ca Systems, HEP/Astronomy UVic
