For some reason my installation of Ubuntu 11.04 is messed up and Unity doesn't start automatically. I can't find what command I need to start it nor how to make it start at boot time. (Running...

I've been running 64-bit Ubuntu for about 2 years now, but a few days ago it developed serious problems. Whenever I would load a Flash page* the computer would crash... well, sort of. The screen...

Excellent, thanks!

I have a collection of text files that comprise a mailing list archive. I grep them to find an email that interests me, then open the file in a text editor to find the surrounding paragraph of text....

Oh, that's it -- it was formatted with Windows CR/LF. Thanks!

The $ seems to fail for me. I'm using GNU grep 2.5.4 (that is, nothing out of the ordinary, just what came with my distro) but I can't get the final anchor $ to work for me. (^ works as usual.)

Thanks!

I have a 3 GB text file that I would like to split. How can I do this?

It's a giant comma-separated list of numbers. I would like to make it into about 20 files of ~100 MB each, with a custom...

It's a hardware system, but I don't think the controller is broken -- it looks like simple OS corruption. I'll try the Debian disk, thanks for the tip!

#1 looks interesting to me -- what calls could a reasonable < operator make that would cause a segfault? I would look at that function and see if there's anything obviously wrong.

fgrep would be good for this -- it's faster to search for fixed strings than true regexen if that's all you need.

One of my very old drive farm servers had an OS fault and can't boot now but I'd like to restore some files from it. I tried booting Ubuntu from a CD, but it couldn't see the drives -- possibly...

I'm not sure what's unclear; I answered reborg's question. Here's a screenshot of the GUI version of what I want to change: the output device from "Internal Audio Analog Stereo" to something else.

Why are you compiling the header file LibSip.h?

This is something of a "Corona688-told-me-so" post.

I found the error, and it was a SEGFAULT-causing error. But it wasn't anything to do with Pari's novel memory management; just a simple mistake...

I don't know what you mean by "custom", but yes I have a library and yes it forces its users to manage memory in a particular way. But memory management is not the purpose of the library: it's for...

Unfortunately I don't recall and it's fallen off the screen. Is there something analogous to .bash_history that keeps errors?

Then the problem was never with memory.



Of course. It is something I need to be concerned with, though -- most of my early programs with the library were unusable (crashed whenever run) by...

I'm just saying that in these functions, the only memory I manage myself is in a single array, char line[]. All other memory management is done by the library. And since library-related memory...

Sure -- but that's not the problem (and it won't be the problem). Every time the library uses the stack it ensures that there's room for what it's creating. Also, the stack is very large -- at...

So any chance of doing this? Or at least, any ideas on where I can start to look for answers?

Huge amounts of memory management -- much more in the calculation parts of my program. Pari essentially forces you to manage all your own memory.

But malloc itself isn't really ever called, not...

No, not nearly all of it -- I have 3200 LOC on top of a 6700 kB library. But those functions, together with 'glue code' for the library, can be compiled into the core application of the Pari...

Right, that's why it's good I rewrote the earlier portions.



This is fortunately only an I/O routine; no calculations to speak of. And after my rewrite it's quite short:
#define MAX_VECLEN...
