This isn't correct; there are two main models for 64 bit computing.
LP64 where longs and pointers are 64 bits (Linux, most UNIX?) and the
Windows model where only pointers are 64 bits. Many might suggest
this is because so much Windows code would break if long suddenly
became 64 bits, but I think the official reason is efficiency within
the API.
In both cases an int is 32 bits. In both models a long long will be
64 bits, no matter what your architecture. It's no wonder people use
Python/Perl/OCaml/Haskell/Smalltalk so they don't have to worry about
any of this.

I've seen a Lotus Domino DB2 database that did this, but I'm not sure if that's the way it usually works or if this was a custom thing. I need to be able to modify the amount/names of data fields stored for an entity so instead of representing the data stored for an entity in fields associated with that entity you would relate it to an another entity which would contain a datafield type field and its associated value, so different rows in the parent table could possibly have different datafields associated with it. E.g The parent table is person and it holds common data amongst all people - it has primary key of personID. There is another table assoicated with person called personDetails. This would have fields personID, dataType and dataValue. It might have records like the following: personID, dataType, dataValue 1,phone,123456 1,email,test@test.com 1,state,NSW 2,phone,987456321 2,state,VIC 3,phone,789456123 Of course this is just an example - the parent entity could be anything. Hope someone can put a name to this sort of design. I want to research into this to see how people search effectively in this design and its performance compared to traditional methods etc etc. Performance was ridiculously bad, and getting the data back out into a more sane format was a nightmare. Searching will suck because the index over the dataValue column will be trying to do several things at once, and missing values will be a problem. I have done it myself once, but I knew it was a nasty hack, and didn't care about the performance issues. It was a nice easy way to get the ACID stuff for free without trying to re-invent the wheel. I'd say that if you don't want your data to be relational, there's not much reason to be using a RDBMS. Maybe an object database would be a better idea if that's what you really want to do.

If it's to be run un-supervised, especially on boxes not under your

on trusted machines, then lock them down (run a browser in kiosk mode?),
not much they can fiddle with if they can't get out of the test. Even if
they're not trusted, it should be possible to at least make it

They can't fiddle the test if only the server knows the answers.
If it does have to be on CD, then HTML would work well too. How the test

something open source to do that with.

I was actually intending to write up some additional references and discussion on that page, especially for topics that I wanted to cover but didn't have time for (e.g. garbage collection and meta-programming), but I figured that if people are actually interested in all that, they can ask me and I'll add to the page later :). Simply fascinating. As a programmer who's been through C then C++ (still a fave!) then on through scriptors like perl, I found the paper very enlightening. I've dabbled in Haskell and found out my onw programming limitations ... need more work in the ML/functional area. I could probably do with a good dose of Lisp as well. Thanks for the feedback Rick. Unfortunately the presentation didn't cover anywhere near as much as I really wanted to cover: I basically spent the entirety of the talk going on about type systems, which wasn't my original intent, but I think it worked out OK. I guess I can cover everything else in a future talk, if people are so inclined ... Any references you have on these topics most appreciated. References, hmmm ... a big, big problem with Haskell is that most of the references you can find are papers; not books or easy-to-learn tutorials. That wouldn't be too bad, but the papers are usually targeted at people who already know the language: a lot of Haskell development right now is involved with advancing the language, and is no use to the beginner and is completely overwhelming. I've found that any introductory books on Haskell are usually targeted at somebody who's completely new to programming, or assumes that you have a functional programming mindset already. (Keep in mind that a lot of the Haskell language designers and implemenators are _really_ smart, and they tend to live in ivory towers rather than try to figure out what the masses are up to :). I don't think the language is actually that hard to learn, but I haven't yet found a book or tutorial that presents the ideas in a digestible way to someone who's new to the language, but is already an experienced programmer using imperative or object-oriented languages. That said, probably the best bet for learning Haskell is Hal Daume's Yet Another Haskell Tutorial: http://www.isi.edu/~hdaume/htut/ I find that the start's pretty slow, and presents things in an order I wouldn't choose if I were to help someone understand the language, but lots of other people have liked it, so hopefully you might too. Another tutorial you may find useful is Tom Moertel's Haskell for Perl Hackers talk: http://community.moertel.com/ss/space/Talk+-+Haskell+for+Perl+Hackers Which covers the basics quite well, but unfortunately doesn't have the time to dive into why the basics are the way they are, and IMHO doesn't really whet the appetite for functional programming. e.g. he explains what higher-order functions are and gives an introduction to Haskell's very powerful type classes, but doesn't explain how make programmer better by showing real, concrete advantages over similar ideas in OO languages. Still, it's a good talk, and most likely he couldn't get deeper into those topics because of time constraints.

Re: [SLUG] Which open source license is best

Maybe it is the one true OS license, but maybe we don't actually need or want a 'true OS license' in every case. I know there are thousands of licenses I would like to classify them: a) BSD like - use how you want includes Public Domain. b) LGPL like - for libraries. c) GPL like - can never be used in conjunction with closed programs. d) Corporate - pay for use in many forms - includes shareware. There are many ways to use code, at runtime, linking, directly copying in full or just taking bits of it. I think the Free software licenses are not so much about what you can and can't do, just that you must *always* provide source to anyone else who will 'use' (by normal execution) a work incorporating it. Where GPL and LGPL differ is the definition of 'a work incorporating it', such that software which just calls the existing LGPL code at runtime is not counted as 'incorporating' it, so is not covered by the requirement to provide source. For the record. I believe that LGPL is the only true Open Source license. a) It allows me as a professional programmer to use it anywhere I want. Yeah, but the 'use' you have here may not be not the same as 'use' in all the cases above. b) It obligates the me as a professional programmer to release any patches back to the community. The moral clause it you like. Personally, I'd like to encourage as much open source development as possible, so I'd go with pure GPL for any library code I might want to release. Please play nice! My take on it is that anyone is free to use GPL code for whatever they wish. If they want to give it to someone else, it's not them using it anymore, it's the recipient.

The script should continue running after the warning I think, do you see any other errors after that? Not being a programmer in any shape or form, I'm guessing that the Red-Carpet extras pkg is trying to import a python module (C API) from an earlier version of Python (FC2 has python 2.3.3-6). I therfore assume that I either need to:- 1) create a symlink to point the old module (1011) to the current module (1012), or Nope, that won't fool it =) Can you get a more current module to match your python version? 2) edit the appropriate red-carpet pkg ( I believe that they are all python scripts) to change the import module request. The line in question is just this bit: from xxx_red-extra import * which tells python to look in various places for a module called xxx_red-extra, most usually in it's 'site-packages' dir. The problem is it can only find the 1011 version. What you might be able to do is have an older version of python run the scripts, that way the module might match. Something like changing /usr/env/python to link to python2.2 instead of python2.3 would probably do it. You can see what version python you have on either system by just running 'python' in a shell.

There's some interesting reading fairly early on (starting line 35). http://grumbeer.dyndns.org/ftp/linux/kernel/patches/misc/cbd-2.4.0-2.patch I tried to patch it into the 2.4.22 source and lets just say it got beyond me as after fixing up the rejects it really wasn't going to build nicely. Right now I'm seeing if I can build a 2.4.2 kernel I found from a SRC RPM on a RedHat 7.1 CD set with the hope that the patch will have more chance of building. The point of this excercise is to build as system that can modify this partition, hence I don't care what kernel it runs. Just thought I'd write this email whilst waiting for the build to finish. The time spent on this so far is more than it's worth so my client is pursuing other avenues - I'm mainly doing this because I belive it may help some other clients that have a similar problem down the track and some stuff we've run up against in the past. I'm prepared to give an EverythingLinux discount in return or something like that. It looks like it's a read-only filesystem, so dunno if there's any point getting that driver to work? Seems like the mkimg program in there takes an existing filesystem and compresses it for reading by the CBD driver, so maybe you could get away with just writing something to decompress an image, based on what mkimg does to compress it.

The parallel port dongle is not for copy-protecting the software, it's for ensuring the devices that the software is designed to configure aren't tampered with by unauthorised persons. I have been running dosemu as root. There are no hardware problems, as I'm dual-booting, and the software works fine under win98. Subsequent investigation uncovered a feature for detecting a parallel port dongle in the software I'm trying to run, and it does detect the dongle under dosemu, but still no communication. So the problem does seem to be, as one clever chap suggested, with the serial port. At this point, I'm again stuck. The PC is an IBM 300PL, and doesn't seem to have anything particularly unusual about it. The IRQ and IO settings for the serial ports can be configured in the bios, and are on the standard settings. It is a plug-and-play bios, but the Plug and Play OS parameter is set to no. setserial /dev/ttyS0 returns the expected result; no error messages. I tried configuring dosemu for low-level hardware access to the serial port, as recommended for the parallel port, with no joy. I've not seen any mention on Google of people having to do this with the serial port, but no harm in trying. I had an (unused) internal modem in the PC, which I ripped out in case it was causing a conflict, but no improvement. I have to admit to being nearly completely ignorant of how serial ports work. Anybody have any clue what may be going wrong, or how to isolate the problem? Hi Matthew, I suppose you have the speed / parity / data bits / stop bit settings to match what's on the other end of the serial cable? Maybe you could find a null-modem cable and connect it between your serial ports, then run a DOS comms program in DOSEmu and minicom on Linux.

Re: [SLUG] A valid analogy.
Ben Donohue wrote: Sorry Richard but I disagree with this analogy. Evolution theory is based on getting better from NON intelligence. Intelligence is NOT in the equation. Oh no. So you're a creationist then? Linux and other free software is based on the collective intelligence of a whole lot of very smart people. If I was a programmer I would be a bit insulted if someone said my work, hard thought and know-how was in fact based on random input. I'd object and say that I don't just type in random characters into the keyboard along with a zillion other programmers and there happens to be the odd one that makes a good program. AND then some other RANDOM process figures out which is the best working program and includes that in the Linux kernel without any testing or whatever. NO. It was mostly your choice of language that tipped me off, but this ridiculous statement shows that you have no clue about what you're arguing against. Evolution by natural selection can be defined as the non-random survival of imperfectly replicating enities. Notice the *non-random* bit? Look at it this way: Say many people decide to fork XFree86, and the choices they make about what to put into their new forks are fairly random. The forks will obviously not end up identical to the 'parent' project: imperfect replication. Over time, some will gain more widespread use than others: non-random survival. Therefore, XFree86 has 'evolved'. Linux changes and gets better and better over time as bit like modern car design or jet aircraft from biplane over time. It's refinement over time but it's NEVER random. How can something get better without intelligence behind it? Linux is MADE to be virus resistant by design. And design means a designer. And a designer means intelligence. Linux people are intelligent people. THAT'S why we don't get viruses. We use our intelligence. Try reading up about things such as the theory of evolution, emergent behaviour, genetic programming or biology in general. I don't think SLUG is the place for proselytising either, thanks very much. Felix Richard Neal wrote: The nearest single analogy I can come across that explains Linux security is Linux is based on an evolutionary development platform were the fittest and most diverse survive. Were windows has a forced evolutionary development based on what sells software. As anyone who has studied evolutionary science can attest the more diverse and random your genetic makeup, the higher the probability of survival in the natural ever on going virus arms race. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Is there a problem when reading a barcode printed using inkjet printer or may be the paper. Is there any suggestion? First, make sure you added the start/stop characters: '*1234*'. If that's OK, try a bigger font size such that the stripes are nicely defined. If the stripes are distorted by your inkjet then you will have problems scanning. If you're only using numbers, interleaved 2of5 is a much better bet, it only needs to encode 0-9 and a checksum, so you get much bigger stripes for a given code length.

Does anyone else have a problem performing data migration from Linux to more pains?? Yes! But also have a few solutions for you: Linux has no trouble at all writing to FAT32 partitions, so if there's a bit of room left on your drive you could make one of those to share files between OSes. If there's no room left, you could steal a bit from your Linux swap partition, enough for a few big MYOB files certainly won't hurt. There's a program called explore2fs which will let you copy files from ext2 and ext3 partitions under Windows: http://uranus.it.swin.edu.au/~jn/linux/explore2fs.htm I wouldn't trust it to write to your Linux filesystem, but reading can't hurt. Also, a network card can be had for about $15.00, so if your laptop has a port built-in, it's probably the best way of sharing data with a desktop PC under either OS. If you share a drive on the PC, your dual boot laptop could then use it as a way of sharing files between OSes too. Maybe a CDRW drive would be the go to solve weird CD issues?

Not necessarily, but it might be easier that way in the long run. The way I understand now is as follows: 1. Connect to the server via SSH; 2. Start vncserver on the Linux server; 3. Using Teraterm or Putty from Windows sends some syntax commands to open up a port for listening; 4. Fire up vncviewer on the Windows client and connect using the port using some syntax. Step 1 and 3 can be combined, i.e. you start the ssh session with the port forwarding active to start with. If these steps are correct, I need to know the syntax for Windows for Teraterm for step 3. Anyone uses Windows as their client to connect ? Not me sorry. Felix snip -- SLUG - Sydney Linux User's Group - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug

I remember reading about this from a url on the web. I can't find that url anymore. Anyway I did not really understand it properly. I can help with this bit at least, you can use the -L option to SSH to forward the VNC port on the server to a local port. ssh -C -L listen-port:host:port If VNC on your server is on port 5500, you might do: ssh -C -L 5501:server-ip-address:5500 then, on your local machine (not in the ssh session) you can type: vncviewer localhost:5501 to connect via the tunnel.

Or is there some other way? You want the mtu option in the interfaces file, like so: iface eth0 inet static address 192.168.17.3 netmask 255.255.255.0 mtu 1490 Tried that, but it didn't seem to work. I'll test it again. The man page didn't mention an mtu option though. I'm not sure if you can use mtu with dynamically configured interfaces. If not, then use the up option to run ifconfig when the interface is configured, like: iface eth0 inet dhcp up /sbin/ifconfig eth0 mtu 1490 Yay, that sounds good. I swear I did RTFM, but didn't see the up option as being relevant at the time. =) or something. There's lots of other funky stuff you can do in the interfaces file. I highly recommend browsing the man page some time. :-) Will do. Thanks, Felix -- SLUG - Sydney Linux User's Group - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug

Re: [SLUG] Quake III 4 Linux
Grab the installer from one of the mirrors here: http://www.bluesnews.com/files/idstuff/quake3/linux/linuxq3apoint-1.31.x86.shtml Once installed you can copy the .pk3 files from your Windows Quake III CD or another partition.

Personally, I am happily windows-free, but I can't see any obvious rsync/sftp/gui windows client for my command-line-challenged colleagues. I've looked briefly at PuTTY sftp and it works fine, but the version I was looking at was totally command line. Did I miss something? There's an SCP client for Windows called Secure iXplorer which works quite well. http://www.i-tree.org/gpl/ixplorer.htm They have a non-gpl version with some more features available for $ too.

The old Laplink for dos systems had a self installing system. That sounds like a security nightmare, but I wonder if there is anything similar that I can use to transfer communications software onto this. Any help gratefully accepted. A TFTP client would probably fit on the floppy, then it could get other files off the network (into a ramdisk?). http://rpmfind.net/linux/RPM/redhat/7.2/i386/tftp-0.17-14.i386.html Good luck =) Felix -- SLUG - Sydney Linux User's Group - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug
Re: [SLUG] MySQL userid / password problem
Try
# mysql -u root
which will work only if you have no password set for the mysql root user.
Then
mysql SET PASSWORD FOR root=Password('x');
mysql quit
Then your other commands should work as they are written.

Subject: [SLUG] MySQL userid / password problem
Dear list,
I am trying to install an accounting package that uses a MySQL database.
The installation instructions say:
5a Setup MySQL database
mysqladmin -u root -p create bw_accounting
So, when I try to do it I get an error eg
[root@plaza /root]# mysqladmin -u root -p create bw_accounting
Enter password:
mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user: 'root@localhost' (Using password: YES)'
[root@plaza /root]#
I have never created a MySQL admin account therefore it does not have a
password. How do I create a admin account?
Am I totally off the mark?
regard,
Richard Hayes

Re: [SLUG] [OT] burned on a deal
AFAIK auction houses are treated as second-hand goods dealers, and are not under the same obligations as the manufacturers or distributors of a product might be. A lot of consumer electronics goods arrive in Australia with non-standard, usually european plugs, due to the costs and logistics of a doing a seperate production run, especially the more exotic HI-Fi gear. Most other countries will have safety regulations as stringent as here, so as long as it's intended to work with 240V 50Hz it's probably OK. The 'c-tick' mark now required on electrical goods relates to standards for the levels of electromagnetic interference generated by or inflicted upon devices. 99.9% of the time a well designed product sold elsewhere will pass these tests (which are not cheap to have done). If they won't take it back, or you can't be bothered posting it, I'd replace the plug, and buy a US-style power board or a couple of IEC leads, which you can get here fairly easily.
