Run hddtemp as user

If you want to get temperature of your hard drive, you can simply run

# hddtemp /dev/sda

This method has one disadvantage - hddtemp must be executed as root, otherwise you will get

/dev/sda: open: Permission denied

But there is a quick solution to run hddtemp as a normal user. Most Linux distributions have hddtemp daemon. After you run it you should be able to use just telnet or netcat as a normal use to get your hard drive temperature:

~ telnet localhost 7634

Increase USB Flash Drive Write Speed

The one of the biggest problems of usb flash drives is a slow data write speed. This article will guide you through the process that can possibly increase your flash stick write speed. Okay, first I bought Transcend 8GB usb flash stick. It had been formatted with FAT32 filesystem initially. So I decided to run data read/write speed test. Mount the filesystem and execute following # hdparm -t /dev/sdb /dev/sdb: Timing buffered disk reads: 102 MB in 3.05 seconds = 33.43 MB/sec $ dd count=100 bs=1M if=/dev/urandom of=/media/disk/test 100+0 records in 100+0 records out 104857600 bytes (105 MB) copied, 29.5112 s, 3.6 MB/s The disk read speed is good enough, but the write speed is not so good. That's because most of NAND flash drives (the most commonly used flash sticks) have 128k erase block size. Filesystems usually have 4k (4096 bytes) block size. And here we came into problem. If the filesystem blocks are not aligned to flash drive blocks, the performance overhead during disk writ...

Alsa Audio Meter

If you need to watch the realtime sound output level on some graphical meter, you might consider difficult to find the program for these needs. After some searching I found nice software called ameter especially for these functions. This program can be used with the most of ALSA and OSS apps. After program installation you should create .asoundrc in your home directory with the following contents: pcm_scope.ameter { type ameter } pcm_scope_type.ameter { lib /usr/local/lib/libameter.so } pcm.ameter { type meter slave.pcm 'hw:0,0' #can be hw or hw:0,1 etc... scopes.0 ameter } pcm.dsp0 ameter The program source can be downloaded from here Also I have created an ebuild for easy installation on Gentoo Linux. Simply add it to your local overlay # Copyright 1999-2009 Gentoo Foundation # Distributed under the terms of the GNU General Public License v2 # $Header: $ EAPI="2" DESCRIPTION="Alsa meter plugin for audio software with GUI" HOMEPAGE="http://laugeo.free....

Gentoo Portage SquashFS + zsync

If you are Gentoo user and you're wondering about how to reduce portage tree disk usage and makes emerge --sync faster, this article is for you. Lets talk about key problems of portage tree: Large disk usage because of uncompressed text data Heavy inode usage because of huge amount of files The above problems result in excessive disk I/O during emerge operations. The most popular solution is to squash the portage tree. It is well-described in  this article . But I've made an easier  script that can handle all the headache for you. I hope you like it! :)
