loading module during pxe boot
by Eric Doutreleau 28 Sep '10

28 Sep '10

i m trying to install a dell precision T1500 but i have the following stated here https://bugzilla.redhat.com/show_bug.cgi?id=525966 When i pxe boot my comp the network card is not discovered then i can't install the machine. The bug is closed because there s an updated kernel but no pxe installation images have been made. There s a workaround to solve the problem it s to load broadcom module bedore tg3. is there a way in anaconda to force the load of a module ? I can't make a dvd installation as i have numerous computers with this card with different configuration. and all are in my cobbler server then a network installation is really needed. Thanks in advance for any help

Hi. I need to convert a bunch of ascii-files to utf-8 encoding. Now files have the following encoding: $ enca poster.tex 7bit ASCII characters Whatever I do (enca, iconv) I'm unable to change it to utf-8. Is it possible at all? TIA -- Hiisi.

Boot blocks of a bootable CD
by JD 27 Sep '10

27 Sep '10

Given a bootable CD or DVD (either the medium itself, or the iso file), is there a way to extract the boot blocks from it for use in creating a different bootable Cd or DVD? Would it even work?

gnupg secret key vs session key
by Geoffrey Leach 27 Sep '10

27 Sep '10

My use of gnupg is very simple (or so I thought) I created a user (defaults accepted) with a nice long passphrase I then encrypted a file using --symmetric I decrypt the file %gpg -d ... You need a passphrase to unlock the secret key for ... <enter the secret key from user creation> gpg: Invalid passphrase; please try again ... two more attempts, same result gpg: 3DES encrypted session key Enter passphrase: entering the passphrase created above works fine. I understand that secret key is different from session key, but I don't understand why the passphrase is not acceptable in the first case, but is in the last.

Re: Computing cpu's clock in cycles per second
by Wade Hampton 27 Sep '10

27 Sep '10

Did you look at using the RDTSC instruction to read the cycle counter? http://en.wikipedia.org/wiki/Time_Stamp_Counter Sample this over an interval to get an estimate of the clock frequency based on this counter. __inline__ unsigned long long int rdtsc() { unsigned long long int x; __asm__ volatile (".byte 0x0f, 0x31" : "=A" (x)); return(x); } I use gettimeofday() calls to check the wall-clock time, usleep(n) to sleep for a long time (second or more), and rdtsc to compute the cycles.... Seems to work well. Cheers, -- Wade Hampton

Re: Scottrade streaming quotes fixed with java jre
by T.D. Telford 27 Sep '10

27 Sep '10

Thanks to the suggestion of Pscium, I removed the openjdk and installed the java jre. The non trivial instructions do to this are at: fedorasolved.org/browser-solutions/java-i386 I use the x86_64 version of firefox, so used the 64 bit version of java jre. Unfortunately, to see the problem you need a Scottrade account. Once you login, there is menu on the left hand side: Scottrader streaming quotes. If you use the openjdk the 3 major national stock market averages are messed up and there is a large blank space at the top of the screen. With the java jre this is fixed. Thanks to all that replied.

Re: Re: Are all cores unlocked?

Approximately, yes. Your machine is also not discharging its battery quite so fast, nor is it generating more heat unnecessarily for the modest level of CPU activity you are now requesting of the machine. How an I speed it up? Ask the CPU to do more work. Recalculate a large spreadsheet. Spell-check a long document. Do a database lookup. Better yet, do them all at the same time. If your bandwidth, as opposed to the machine's, isn't interested in all that excitement, but you still want to exercise the processor more, find some program to run in the background while you do less compute-intensive tasks. For example, you could join the folding@home project: http://en.wikipedia.org/wiki/Folding@home Or you could just be content that your computer knows how to run in an idle mode instead of racing around at top speed when it doesn't have anything to compute at the moment (which is most of the time, usually). One of the larger challenges of contemporary computer science is to figure out how to use, most efficiently and effectively, the multiple processor resources now more commonly available. Software has to be made aware of how to best use the newer hardware, and this is a non-trivial task. Ken

Re: Scottrade streaming quotes errors on latest fc13
by T.D. Telford 27 Sep '10

27 Sep '10

Scottrade streaming stock quotes is initiated from firefox, and uses a Java applet. fc10 is fine and the fc13 dvd install, with no updates is good, but the latest fc13 changes (as of today) show the major index quotes are missing and there is a big blank area at the top of the display. Since I manage my stocks with this program, I will not be able to use fc13 until it is fixed. Regards, Doug
