  1. Forgot a language on Nordic Countries to Promote Open Source · · Score: 1

    Faroese

    I think that makes at least 10!

  2. Quantum theory on LavaRnd: A Open Source Project for Truly Random Numbers · · Score: 1

    I shoot a photon through a double-slit. Where does it land? You can't tell. Do you really believe that that's chaos?

    If you have a wavefunction describing your system, and you observe it, the state of your system will be random, as allowed by the probability distribution of your wavefunction.

    The uncertainty principle. Is that chaos? Wrong.

  3. Use SSH on Citrix-Like Server for Linux? · · Score: 1

    I found that you can get pretty good performance if you tunnel X over a compressed ssh connection. Applications take a while to load, but they're pretty zippy once they've started.

    From linux you can do:

    ssh -C machine.domain ...
    xterm &

  4. Re:What I want explained to me... on C++ Templates: The Complete Guide · · Score: 1

    I suggest you read the section "Template Instantiation" in the gcc info documentation. Basically you never get an int version of Foo instantiated, as the compiler has to see the definition and usage in the same compile. gcc currently can't go back and work out where the source code is for the template and recompile it for the type.

    You can get round this by putting the entire template definition in the header file, which may lead to massive code bloat if your linker doesn't combine all the multiple definitions... Read the info page for lots of useful information on this.

  5. Ken Macleod on Top 10 New Sci-Fi/SF Authors? · · Score: 1

    For amazing political ideas (anarchic communism and capitalism in a heady mix), well written with good plots, try Ken Macleod. Books include "The Star Fraction", "The Cassini Division" and "The Sky Road".

    But also read non sci-fi. Try using a public library to get into new authors.

  6. Processes are lightweight in linux on Information for Managers - Understanding pthreads? · · Score: 2
    Processes are lightweight in linux. See e.g. this. If you are on Solaris or Windows then you might have to look at threads to get speed (but not security). It may be that threads are more lightweight in Linux nowadays, but process creation is fast under linux.


    Processes get you a number of advantages above.

  7. HSBC on Credit Card Websites Who Support Mozilla? · · Score: 2
    I have a HSBC card here in the UK, and I can do my normal banking and look at my credit card transactions with Mozilla 1.2.

    If you are going to change card, make sure you tell them why you are leaving them. If enough people do that they'll realise their browser policy is stupid and is losing customers. You might want to mention that AOL might be using a Gecko based browser in their next software release.

  8. Maybe he has gone the way of Donald Knuth... on Kernighan Teaches... Liberal Arts? · · Score: 3, Funny
  9. Blocking plugins on Mozilla 1.2 Beta Released · · Score: 2

    There's a bug for blocking plugins from various sites. See bug number 94035 on bugzilla.mozilla.org (no link as bugzilla does not allow ./ linking)

  10. IRAF and gimp on Software and Tips for Astrophotography? · · Score: 2

    I'm an X-ray astronomer. Optical astronomers often use IRAF to create the images, but other software like GAIA can be used. SAO's ds9 and saoimage can be used to view the data. Professional astronomers normally use the FITS format to store observational astronomical data.

    I personally (after using CIAO to make the basic images from my X-ray data) combine them using Gimp (it reads FITS files) and then use it to manipulate the colours.

    Sorry for the lack of links. Google will find most of those.

  11. xine is in (null) on Red Hat 8.0 Reviewed · · Score: 2

    Xine was shipped with the (null) beta. I'm surprised if it itsn't in 8.0. Perhaps it isn't installed by default? Perhaps it isn't on the menus. I can't check as I don't have access to 8.0.

  12. The $ idea on Assembly Language for Intel-Based Computers, 4th edition · · Score: 1

    The $ ending a string idea dates from at least CP/M. When you passed a string to print to BDOS (Basic Disk Output System), you terminated it with a special character (set with another system call), traditionally $.

    Sigh, CP/M - no directories, but you did have passwords on files!

  13. Re:Our issue on Can We Finally Ditch Exchange? · · Score: 2

    The webmail service the University of Cambridge uses is pretty good, but it doesn't seem to have any identification. Maybe it was developed in-house or is a highly customised code. Perhaps one of the guys there would let you know what they're using (look around for contacts).

    See this

  14. Re:Outgoing easier than incoming on ADSL Bandwidth Aggregation w/ Multiple Accounts? · · Score: 3, Interesting

    I think nmap can make packets with forged source addresses.

  15. people in Britain on Considerations for an Oversea Move? · · Score: 2

    Just a couple of comments:

    o The rain - the weather in Britain is pretty variable, both in terms of location and time. East Anglia is almost arid from the rainfall point of view. It probably depends on where you come from whether you will like the weather. Quite a lot of people like the variability and seasonality. Spring and Autumn in Britain can be fantastic if the weather is good. Summer can be wonderful except when you get weeks when it keeps raining!

    o Grumpyness? It's just a bit of a culture clash. People here tend to not be so open to people they don't know and don't welcome personal questioning. Once you get to know someone they'll appear less grumpy. They may be taking some aspect of your personality badly (it works both ways), however here they wouldn't tell you what they don't like about you.

  16. Camera? on DRM Helmet · · Score: 2

    Couldn't you put a head shaped camera in the helmet to get your unauthorised copy?

  17. It would be more interesting if... on First Benchmarks of AMD Hammer Prototype · · Score: 5, Interesting

    They tested some software which had been compiled for 64 bit mode. With the large number of 64 bit registers the hammer has there should be some significant speed improvement.

  18. And including the new Emacs!! on Red Hat Linux 7.3 Released · · Score: 2, Interesting

    emacs-21.2

  19. The STL is pretty good on Downsides to the C++ STL? · · Score: 1

    Once you've got used to it, the STL is a great productivity booster. No more writing those generic data structures. I'd say anyone using C++ who doesn't know the STL is missing out on a large chunk of useful knowledge. Unfortunately it takes a long time to master it (I haven't reached that stage yet!).

    Problems? I find that executables can become quite large if you use the templates all the time, without thinking how large the code for all these classes can be. You have to think about using vector<T*> rather than vector<T> (vector<T*> is specialised).

    Another problem can be the warnings from compilers. gcc-2.95 has awful warnings for errors in using templates. It's good to have a modern compiler (e.g. gcc-3.1), which doesn't leave you with an awful mess of < < blah > blah >. This is a general problem with C++'s template syntax, which can become very messy! I'd love a language which really cleaned up C++'s syntax generally.

  20. Nautilus on Music Filesystems? · · Score: 2, Informative

    Nautilus has a music view, where it shoes the id3 tags as if it was an album sleeve. I'm not sure whether this is searchable though.

  21. Hmmm... on Swapping IDE Drives in Linux without Rebooting? · · Score: 1

    I remember somewhere reading about unloading the ide module and reloading it. You might not be able to unload it unless you stop all the ide drives being used.

  22. I was at the talk on Stallman on Software Patents · · Score: 3, Interesting

    He is a fantastic speaker... he managed to speak for 1.5 hrs without notes in totally engaging fashion. I didn't realise he'd be so good. He did have some odd physical habits, but he spoke very well. He was rather rude to the questioners, though.

  23. Recent kernel? on Swap Performance in Linux · · Score: 1

    Are you running a recent kernel? It's got a lot better in the newer 2.4 series. We replaced the original kernel in RedHat 7.2 with the errata kernel, and it is much better!

  24. I have a python script on Split Print Job to Color and B&W? · · Score: 2, Informative

    I have a script which isn't generally appropriate, but it might give you an idea of how to do it. It takes a dvi file and generates a set of postscript files, each contain black and white and colour sections.

    See dvicoloursplit.py

    (released under the GPL)

    It works by generating postscripts for each page, converting to a bitmap, then scanning the bitmap for colour pixels. Not very clever, but works. I tried to examine the postscript itself, but it's very hard to find the colour in a postscript. It can easily be "encoded" in a jpg bitmap, or something else.

  25. Fortunately... on What's the Worst Acronym You've Ever Heard? · · Score: 1

    Cambridge University Netball Club isn't called a "Team" instead...
