How to auto-update Chromium on Mac OS X, Linux and other

By shad on Wednesday, January 6 2010, 12:23

I want to try to use Chromium as my first web browser. But for the moment, Chromium suffers from a lack of package maintaining though it targets developers.

On my Gentoo Linux, I let portage to handle my Chromium version. But I also use Mac OS X at work, so I have written a little shell script to auto update my Chromium.app.

Put the content of this scripts wherever you want and make it executable ($> chmod 755 chromium_update.sh).

#!/bin/sh
# Chromium update script
# - by shad <shad@zaphod.eu>

# mac | linux | ...
OS=mac
LATEST=$(wget -q -O - http://build.chromium.org/buildbot/snapshots/chromium-rel-${OS}/LATEST)
INSTALL_DIR=/Applications
TMP="/tmp/update-chrome-$RANDOM"

(
mkdir $TMP ; cd $TMP
echo Download...
wget -q -O chrome.zip http://build.chromium.org/buildbot/snapshots/chromium-rel-${OS}/${LATEST}/chrome-${OS}.zip
if [ $? -ne 0 ] ; then
	echo Cannot update.
	exit 1
fi
echo Unzip...
unzip -qq chrome.zip
echo Copying...
rm -rf "${INSTALL_DIR}/Chromium.app"
mv chrome-$OS/Chromium.app "$INSTALL_DIR"
)

rm -rf $TMP

Then, set a crontab rule to choose the update interval ($> crontab -e). Mine runs every day at 12:00.

# Run Chromium update script every day at 12:00
00 12 * * * /Users/shad/mbin/chromium_update.sh

I hope it will be useful for someone as much as for me.

FreeBSD on the ASUS Eee Box using an USB flash drive

By shad on Sunday, January 18 2009, 20:28

I wanted my personal server to be closer to me. So I invested few days ago in the Asus Eee Box, thinking it is the best configuration for a light server at home.

I moved this blog and all my services from my dedicated server to my new one.

To setup FreeBSD on this kind of machine, you have two ways to do it:


Creating a bootable USB flash drive by using the original ISO image is a bit annoying if you haven't got a FreeBSD station yet. I have been using the fbsd2img.sh script,

I share my USB flash drive image: 7.1-RELEASE-i386-bootonly.img.
To setup the USB flash drive, use "dd" (/dev/XXX is the device of your USB flash drive):

dd if=7.1-RELEASE-i386-bootonly.img of=/dev/XXX bs=1m


Here is the result of the server hosting this blog :)

Windows Vista: BOOTMGR is missing!

By shad on Monday, February 4 2008, 17:04

    I bought an additional hard drive last week to increase my storage capacity and to add a partition to backup data. I decided to move my Windows Vista installation to the second harddrive. Linux and grub are installed on the first one.

    Vista creates a Boot directory when it setups the MBR. I noticed that Vista does not create this directory when it is installed on the second harddrive, probably because the boot loader is on the first one. So after I restored grub to handle both windows and linux, when I tried to boot Vista, I saw the message "BOOTMGR is missing!".

    The boot directory cannot be seen on Windows systems, I verified its presence on my Linux system with the Windows partition mounted.

    I found a little trick to force windows Vista to create boot directory and bootmgr, I configured the bios to disable the first harddrive. Then I repaired the windows Vista installation with the dvd, the repair program created the boot directory and bootmgr program. Finally, I re-enabled the first harddrive.

    It's important to add a small setting to grub configuration to make Windows believe it is launched from the first harddrive. Grub is able to change the bios harddrives order virtually.

Duplicity: simple, efficient and secure backup solution for Unix

By shad on Thursday, January 24 2008, 19:51

Backuping data is a real problem. Investing 2 RAID 1 harddrives is a little expensive for a workstation. Duplicity is able to do incremental backups with the rsync algorithm. All backuped data are encrypted with gpg.

All duplicity options are available on the official website.

I wrote a small script for automate backup on my workstation.

backup.sh:

#!/bin/sh

ROOT="/root/backup"
DISTANT="ssh://user@zaphod.eu//home/user"
PASSPHRASE="xxxxxxxxxxxx"
KEEP_ARCHIVE="2M" # 2 Months
FILELIST="files.lst"

export PASSPHRASE
duplicity       --include-globbing-filelist "${ROOT}/${FILELIST}" \
                --exclude '**' \
                --full-if-older-than "${KEEP_ARCHIVE}" / "${DISTANT}"

duplicity remove-older-than ${KEEP_ARCHIVE} ${DISTANT}


Then a small file list specifies what has to be backuped or not.

files.lst:

- /home/shad/p0rn
- /home/shad/tmp
+ /etc
+ /home/shad


According to duplicity documentation, a line beginning with a '+' specify a directory or a file to include and '-' for exclude. Be aware of list order.

It remains to add a cron entry for a weekly schedule:

0 0 * * 1 backup.sh | mail -s "Backup Report" root@zaphod.eu


Now your worksation is secured, you can restore any files to any date within the backup delay.
