I want to have a real-time process take over my computer. 🙂 I’ve been playing a bit with this. I created a process which is essentially a while (1) (never blocks nor yields the processor) and used schedtool to run it with SCHED_FIFO policy (also tried chrt). However, the process was letting other processes run as well. Then someone told
Using sed to get an env var from /proc/*/environ weirdness with x00
I’m trying to grovel through some other processes environment to get a specific env var. So I’ve been trying a sed command like: sed -n “s/x00ENV_VAR_NAME=([^x00]*)x00/1/p” /proc/pid/environ But I’m getting as output the full environ file. If I replace the 1 with just a static string, I get that string plus the entire environ file: sed -n “s/x00ENV_VAR_NAME=([^x00]*)x00/BLAHBLAH/p” /proc/pid/environ I

Setting GDB hardware watchpoint/how to set software watchpoint
An earlier question explained that on x86 the size of objects being watched is limited by debug registers. As expected, I can “watch” a double variable. But I can’t watch a double datamember, for example, produces But when you try to continue execution, it says Could not insert hardware breakpoints: You may have requested too many hardware breakpoints/watchpoints. even though
how to interpret a freetype glyph outline when the first point on the contour is off curve
I’m actually working on a renderer that converts freetype glyphs into polylines to control a laser marking system. The problem I have is that I don’t know how to handle correctly a contour beginning with an off curve point (99.9% begin with on curve points!). I’ve searched quite a while now for informations but I couldn’t find anything useful. Thanks

Linux static linking is dead?
In fact, -static gcc flag on Linux doesn’t work now. Let me cite from the GNU libc FAQ: 2.22. Even statically linked programs need some shared libraries which is not acceptable for me. What can I do? {AJ} NSS (for details just type `info libc “Name Service Switch”‘) won’t work properly without shared libraries. NSS allows using different services (e.g.
Retrieve plain text script from compiled bash script
Some time ago, i wrote some bash scripts for my school. I thought it would be very clever to ‘protect’ them, so i compiled them with shc into a binary file. Some weeks later, i lost the uncompiled scripts and now i have only my binarys left. Is there a way to retrieve the scripts back from the shc generated
