I have multiple computers for which I would like to keep files in sync.
I also happen to have a account on DreamHost as a webhosting company. There hosting plan includes a 50GB backup user so why not take advantage of that.

Using information and help from Olaf and patched adb from Flori7500 I can now use Android SDK to connect to my Galaxy.

Here is how I set-up Ubuntu 9.04 (Jaunty Jackalope) so that I could use adb to access my Samsung Galaxy GT-I7500. I can confirm that the same instructions also works after upgrading to Ubuntu 10.04 and Ubuntu 10.10.

Finally I got my Samsung Galaxy GT-I7500.

When I inserted my SIM it directly connected me to my operator here in Sweden (which is 3).
My first surprise was that the networks shows up as "SWEDEN 3" or sometimes only "SWEDEN".
Voice calls works directly without any problems.

Setting up the APN for data connection gave me some minor problems.

== The example setup ==
The following test repository was created and used in the following examples.

$ cd /tmp
$ svnadmin create `pwd`/testrepo
$ svn mkdir -m "Added trunk" file:///tmp/testrepo/trunk/
$ svn co file:///tmp/testrepo/trunk/ testwc



$ echo "Added file in revision 2" > testfile.txt
$ svn add testfile.txt
$ svn ci -m "Rev 2"
Sending testfile.txt
Transmitting file data .
Committed revision 2.
$ echo "Added a new line in rev 3" >> testfile.txt
$ svn ci -m "Rev 3"
Sending testfile.txt

Below are some ideas on projects I would like to get started on (when time comes).

Stuck on a machine with Gnome 2.6 and want Nautilus to open in browser mode by default ?
Well just set the hidden ''always_browse property'' to ''true''. In later versions of Gnome this property can be set using the Nautilus preferences.

gconftool-2 --type bool -s /apps/nautilus/preferences/always_use_browser true |

Here are some quick memos about Oracle. They are mostly here to be a place where I can refresh my memory.

== Start a Oracle databse instance ==

* Setup paths and SID
export ORACLE_HOME=/usr/oracle/Ora901
export PATH=$PATH:$ORACLE_HOME/bin
export ORACLE_SID=mysid

* Start TNS Listner
lsnrctl start

* Startup the instance

$ sqlplus "/ as sysdba"

SQL*Plus: Release 9.2.0.8.0 - Production on Mon Dec 3 11:51:25 2007

Copyright (c) 1982, 2002, Oracle Corporation.  All rights reserved.

Connected to an idle instance.

SQL> startup

As a *nix user I'm used to the "powers of command line". Despite the rumors of being a GUI only OS MS Windows(C) you can do useful things from the command line.

== Systeminfo ==
The equivalent to *nix command such as ''uptime'', ''vmstat'', ''uname'' is one command ''systeminfo''

C:\>systeminfo
systeminfo

Host Name:                 MACHINE1
OS Name:                   Microsoft Windows XP Professional
OS Version:                5.1.2600 Service Pack 2 Build 2600
OS Manufacturer:           Microsoft Corporation
OS Configuration:          Standalone Workstation

== Project summary ==
[http://subversion.pontus.ullgren.com/JUCpio/ SVN]

== What is JUCpio ? ==

JUCpio stands for Java Util CPIO and is a set of classes (a API) for reading and writing cpio files.

It is designed to be similar to [http://java.sun.com/j2se/1.5.0/docs/api/java/util/zip/package-summary.html java.util.zip].

The primary reason I started this project was to learn more about the CPIO file format. The API is currently in a very early stage of development.

== Features ==
=== Implemented ===
* Gives a interface to extract data from cpio files.

While I was installing Windows XP as a VirtualBox guest operating system I got the following error message from the Windows XP installer ''"No valid system partitions were found. Setup is unable to continue."''

The solution was to start the installer with the '/syspart:c:' argument.

Select Disk 0
Clean
Create Partition primary
Active
Assign Letter=C
Detail Disk
exit

format c: /fs:ntfs /x /q

winnt32.exe /syspart:c:
