Last week’s techmail was Increase download speed with Aria2 utility which looks at an incredibly useful and cool file download client. Aria2 is unique because it can grab the same file from multiple sources: http, ftp, bittorrent. It can do it at the same time and then munge the resulting file back together. Makes downloading big files wicked fast. Multi-platform, so not just Linux.

Learn more about how you can use SQLite
This week’s techmail is Learn more about how you can use SQLite which is a bit of a primer on how you can use SQLite to create your own little SQL databases, or how you can use it to manipulate the data stored in SQLite databases found in other programs, like Firefox. I pretty much focus on how you can get information out of the Firefox SQL databases, but it comes with plenty of shiny illustrations for how you can do this yourself on any other SQLite database. Because SQLite is so well-used in many applications, being able to get into your data with a wee bit of knowledge can prove to be useful or just plain old fun for people who like to tinker.
DNS querying with dig
Last week’s techmail was DNS querying with dig which is a little bit of a primer on an indispensable tool called dig. dig is a DNS querying tool that can look up all kinds of handy DNS-related information, and is useful for helping to diagnose networking issues.
How to pre-upgrade Fedora 13
This week’s TechMail is How to pre-upgrade Fedora 13 which shows how to use PreUpgrade (great tool). I used it to upgrade an F12 box and it worked flawlessly, despite the small /boot size. More information on how to use it is also on the Fedora wiki.
Monitoring MySQL with mytop
This week’s techmail is Monitoring MySQL with mytop which looks at the mytop perl tool that can help monitor and diagnose problems with MySQL (mytop is essentially a top for MySQL).
Fan speeds in Fedora on HP Core i7 system
My main Fedora workstation is an HP desktop. It’s got a Core i7 quad CPU (Q9300), 8GB RAM, and dual boots Windows 7 and Fedora 13.
Dear lazyweb, how can I make this system as quite on Fedora as it is on Windows? It’s absolutely silent when Win7 is running, but when Fedora is running the fans are quite noisy. Most of the time the system has a load average of 0.00 so it isn’t CPU spiking causing the fans to go full-bore. For temperatures I have Core0 at about 51C and Core1 at 44C and the other two cores at 48C, but the fans are running at 1583 and 1160 rpm. I can’t get the sensors to pick up temps or fan speeds on Win7 for some reason so don’t have a basis for comparison (tried a few of those “gadgets” and none show me temperatures).
There has to be a way to lower the fan speed on Fedora but I can’t find it. I tried fancontrol from lm_sensors but it complains about not being able to manually set the fans and there’s nothing I can see in the BIOS that’s even remotely relevant.
Am I doomed to a noisy Fedora box? Or is there a way I can make this thing quieter short of buying new fans? (The latter is an option I suppose, but if Win7 can run perfectly silent, then I’m of the frame of mind that Fedora should too). Running an up to date F13 (wheeee!!). Thanks for any suggestions.
