Shell scripts are often running as background processes, doing useful things without running in a visible shell. To write such scripts can be quite painful, as all errors occur out of sight as well. While log files can hold a lot of information, finding the relevant information is a bit trickier. My solution is to log only the errors with all the details to a small database. This database contains tables for the message, the corresponding stack trace and the important environment variables. I have chosen for an SQLite database in this howto, but the same principle works with other databases as well.

NDISwrapper, the open-source project that implements the Microsoft Windows kernel API and NDIS API within Linux for running Windows wireless network card drivers on Linux, has been updated. This effectively native Windows WiFi network driver project for Linux now runs on new kernels, up to and including the brand new Linux 3.8 kernel. This is the first release from the project in more than one year...

Last time around, I had mentioned that I have been able to put down two research questions for my thesis project, where the first was to do a usability test for GNOME3. Moving forward on that direction, I decided on doing task analysis for the usability testing. The process given below is what I narrowed down to, with my rationale for doing so.

With the recent release of Debian 7.0 Installer Release Candidate, the final release of Debian 7.0 "Wheezy" is effectively on approach. For those not up to speed on this major Linux distribution update, here's a list of some of the top features...

Canonical was proud to announced earlier today, February 19, that they are planning to release a modified version of the Ubuntu operating system, for tablets.

While there have already been a number of Radeon Gallium3D benchmarks from Mesa 9.1 using the common R600 Gallium3D driver that supports the Radeon HD 2000 through Radeon HD 6000 series graphics cards, still in existence is the R300g driver. For those still left using a vintage Radeon 9500 (R300) through Radeon X1000 (R500) graphics cards -- basically any ATI GPU roughly between seven and eleven years old -- there's this legacy open-source graphics driver. R300g doesn't see nearly the amount of development activity that the more modern R600g driver sees, but there's still a fair amount of changes. In this article are benchmarks of Mesa 9.1-rc2 on an ATI Radeon X1800XT (R520) graphics card compared to the past four Mesa/Gallium3D stable releases.

As expected, Canonical has announced their plans for Ubuntu on tablets as well as the signing of a deal with a major mobile silicon provider to provide Ubuntu smartphone and tablet chips.

I'm often compared to the Absent-Minded Professor. I take it as a great compliment, because in the movie, he's brilliant. Unfortunately, when people refer to me as him, it's the "absent-minded" part they're stressing—not the "professor" part.

Ingo Molnar has already submitted his x86 platform pull request for the Linux 3.9 kernel that's now officially under development since last night. With the Linux 3.9 kernel will come support for Google's Android "Goldfish" emulator...

Since everybody seems to be Steam-ing and the Steam client is not in the default Fedora 18 repository,

As the CeBIT upcoming convention in Germany nears, Canonical has announced what it will be showcasing at the event–which, in turn, provides some clues about where the company behind one of the world’s most popular open source operating systems might be concentrating its efforts in coming months. Alas, Ubuntu tablets are not on the list. But if you’re interested in Ubuntu on servers in and the cloud, there’s going to be a lot to see in Hanover between March 5 and 9.

This series is proving a lot more popular than I'd figured. Who would have thought so many people enjoy noodling around with Web servers? By popular demand, "Web Served" now enters the bonus round with two things I didn't think I was going to be able to get to: MediaWiki in this piece, and Etherpad Lite in the next.

It bothers many of us everytime we hear about yet another non-obvious, overreaching, and abusive patent—particularly a software patent that is getting in the way of innovation and creativity. Additionally, there is an overwhelming sense of frustration when a regular citizen can't do much to change the current, sad state of affairs.

Dell has announced a higher resolution screen version of its Sputnik laptop, an Intel i7 Ultrabook supplied with Ubuntu 12.04 LTS and aimed at developers, that it will be making it available outside the US and Canada. The screen on the new Sputnik 2 is 1920x1080, a far higher and more developer-friendly resolution than the Sputnik 1's 1366x768 display.

Rumors are not exactly an uncommon phenomenon here in the Linux community, but every once in a while one comes along that is so compelling, such a deliciously tantalizing prospect, that bloggers just can't leave it alone, no matter how far-fetched it may be. Case in point? Oh, it's a juicy one: "Microsoft is having a 'meaningful look' at a full Linux port of Office ... .
