alcatel X220
Hi folks, does anybody have 1st hand experience with cellcom usb modem (alcatel x220) on linux?

Re: suggestions sought for a framework for a quick, dirty, really simple GUI prototype
Quoting Oleg Goldshmidt p...@goldshmidt.org: Hi, I have no - literally zero - experience in creating GUIs of any kind. I face the following task now: there is a C++ program that runs on Linux and basically receives some packets with some data over the network and does some transformations on the data. As a result some data structures are created and updated - potentially many times a second, say, a few times a second for any *single piece* of data. I need a *prototype* GUI that would display and constantly update (parts of) those structures, say strings and numbers with colours and labels and stuff. There may be a need for a drop-down menu for some configuration - don't know yet. Eventually maybe a button or two will be added to invoke some actions. I figure that the simplest way about it would be to make the GUI run on the same Linux machine and write it in C++ for ease of integration. What would be the easiest / simplest framework to use? Is it Qt? Ultimate++ ( http://www.ultimatepp.org/ - just one of the things I found in a simple and brief search)? Since I have no experience it's difficult for me to judge quickly. What is important here is speed and painless ramp-up to some fairly low level. I want to be up and running as fast as possible with as little coding as possible. No need for bells and whistles. No need for long term maintenance. It is for a throw away demo/prototype - and yes, I am sure it (the GUI part) will be thrown away. Any suggestions / experiences / war stories / whatever?

problems with freshmeat/slashdot
Hi friends, am I the only one who experience problems with freshmeat and/or slashdot for last few days? The problem seems to be that connections to image servers is blocked. Who did it? Provider? my home IP (persistent) is in some black list? I have no problems getting these sites from work, and also no problem with text browser. Any ideas?

platform for number crunching---resume
Many thanks for everybody who answered my question. Short resume is following: 1. x86_64 is really the only affordable platform( sure it depends on definition of affordable but anyway people got it right); 2. Good idea is cleaning off the dust from the box and check thermal paste; 3. Is the problem specific to my machine or has general nature still unclear, since: a) gamers forums are full of complaints about overheating; b) nobody provides example of heavy *numerical* load without overheating, kernel compilation for example is not relevant becouse AFAIK compiler does not use floating point calculations and power consumption and heating may be essentially different; 4. All the subject of CPU power consumption and heating is complicated and needs serious investigation. Most of the references I've seen are of anecdotal character, very little reliable physical/engineering information. Probably manufacturers prefer to keep this information for own use.

platform for number crunching
Hi folks, I'm looking for affordable workstation for heavy number crunching, not x86-64 multicore. It seems that multicore systems have problems with cooling (physically it is pretty clear). My current amd-64 4-core machine works fine only if less than 2 cores have 100% load. Rougly 2*100 work 20 min before temperature becomes high, 4*100 can last couple of minuts only. Last year I have already burned processor and do not want repeat the experience. I'll be glad to know my options other than open the box and add fans or set air conditioner in my working place to very low temperature. -- Shimon Panfil: Industrial Physics and Simulations http://industrialphys.com ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

How can I investigate what was the reason? What log should I inspect? I use UPS so the reason might be more interesting that simple power failure. Hi Shimon, You have a sparsely occurring intermittent -- as a matter of fact so far it's a single event. If the cause was software, it's possible you can find a clue in the logs. If I were in your shoes and there's no clue in the logs, I would just wait until the problem becomes frequent enough to be a bother. But if you want to address the problem right now, I'd suggest corrective maintenance: 1) Feel if the power supply is getting too hot, and replace it if so. 2) Vacuum out all the dust from the inside. 3) Pull off, lubricate (electronics lubricant) and reseat all cables. 4) If your motherboard batter is more than a year old, replace it. 5) Disable (open circuit) your reboot button, and replace your on/off button with a simple, non-lighted doorbell button. I learned #5 the hard way -- the reboot and power switches that come with the case can go intermittent, and not just intermittent open, but intermittently close without pushing. None of the preceding is diagnostic in nature, but given the rarity of the symptom, if the log files don't have something telling, the preceding are probably the best use of your time.

I have switched off gdm so Xserver failure should not cause a restart. The box seems not too hot, but the problem might be connected with power, all restarts occur after few hours of heavy load. There is nothing in logs. It looks like restart button was pressed. My box is still under warranty so I can not play with hardware. However I should like to understand how it works. In particular I wander, is it possible that some user program cause immediate restart? Is it kernel which does it, or BIOS or whatever?

debian netinst q
Hi Folks, I've just made instalation of debian 4.0 using netinst CD. All is fine safe a couple of minor things: Installer did not asked me if want graphical login, set gdm or something like that automatically, second it did not asked for root passwd and set something that I do not know and it did not asked me if I want grub or lilo and set grub (I definetely prefer lilo!). So my new debian is completely unuseable. What did I wrong?

How did you boot the installer? If you just pressed enter at the first installer screen it should have presented you with a textual installer that by default would have asked you for root password and also for your computer tasks, if you chose as a task Desktop it automatically installs X11 with GDM and the whole Gnome desktop environment. I see. Can I have X11 without GDM Gnome etc? .. I've never seen the installer not ask for a root password so I don't know how you could have got to such a state.
