We have git repo at github ( and would like to move onto some our corporate box inside our network, for example on internal.bokov.net. This repository is shared for group of developers and all who have ssh access onto internal.bokov.net shall have right to commits onto git repository. So first of all prepare place for git repo at new hosting :
ssh user@internal.bokov.net
cd var
mkdir git_repo
chmod 777 git_repo
cd git_repo
mkdir my_project
cd my_project
git init --bare --shared=all
cd objects
chmod g+ws *
Next clone existing repo and change its settings to point onto internal.bokov.net
git clone --bare git@github.com:bokov/github_project.git
git remote add -t master -m master origin ssh://internal.bokov.net/var/git_repo/my_project/
git push origin master
to start work with new repo just use
git clone ssh://internal.bokov.net/var/git_repo/my_project/
have fun.

The US military has announced plans to buy 2,200 more of the game consoles, so that they can massively beef up the processing power of an existing, PS3-based supercomputer. A “Justification Review Document,” which has oddly been deleted from Google since I found it but is still available at this cache link, explains that, “the new PS3s will be placed in a cluster environment with an existing cluster of 336 PS3s by connecting each of the units’ one gigabit Ethernet port to a common 24 port gigabit hub.”

Update in Amazon Web Services:
2 high cpu instance types : 64 bits – Double Extra Large с 34.2 GB RAM, and 13 ECU (4 virtual cores *3.25 EC2 compute Unit=ECU), 64-bit platform
and Quadruple Extra Large – 68.4 GB of RAM/ 26 ECU (8 virtual cores* 3.25 ECU) : New EC2 High-Memory Instances
Instance prices changes ( us-east is still cheaper thatn eu-west ) : Amazon EC2 – Now an Even Better Value
New service for relational DB ( provisioning, scaling and other nice things ) : Introducing Amazon RDS – The Amazon Relational Database Service
Security stuff : Vulnerability identified in Amazon’s cloud computing
Amazon EC2 – Ubuntu at google groups
5 years ago Amazon announced Amazon Simple Queue Service – top points of AWS for last 5 years

If anyone interested in it – here’s new update for Sun Grid Engine 6.2 – update 4. It almost about bug fixing and man’s changes – list of changes is here. Sources’ tag for CVS is V62u4_TAG (make sense for Grid Engine, ARCo, SGE Inspect ), by the way as I know Hedeby is still 1.0u3.

Public cloud providers : hybrid cloud vs instance types, API logging vs stability – comparing goGrid and Amazon EC2 .GoGrid is officially out of beta, so now it’s time to compare GoGrid with the public cloud market leader, Amazon EC2. Both vendors have relatively stable performance metrics and they both implement the basic functionality of a cloud provider:
- Programmatic control via REST API
- Scalable data storage solution: Elastic Block Storage in Amazon AWS and CloudStorage in GoGrid
- Ability to assign external IP addresses
- Ability to grant root/administrator credentials
- Many options to configure the cloud cluster
- Windows and Linux support
- Web console for monitoring and management
So far, as cloud providers GoGrid and Amazon EC2 look very similar, but practical experience of using them in real-life projects helps us identify some unique features that can be important for specific applications – for highlighed features and bad points for both providers look onto GoGrid is out of beta on Grid Designer’s Blog

Some Sony Vaio owners ( my own is VGN-FZ31ER ) may have MAC is in deep sleep! problems – WiFI doesn’t work under Ubuntu because WLAN driver goes into forever sleep ( some bug in power safe logic I suppose ). This bug can be fixed by adding “noacpi” parametrs to Ubuntu boot command line.

On one of my apache I use suexec to run some tasks – some weeks before I configure all it and all stuff works well, but some days later when I try to run my cgi-perl script I found I have “500 Internal error”. I change nothing in apache config or in my scripts – I just install fresh updates for ubuntu. In apache’s error log I’ve got :
[Wed Jul 29 08:15:28 2009] [error] (13)Permission denied: exec of ‘/usr/lib/apache2/suexec’ failed
[Wed Jul 29 08:15:28 2009] [error] [client my_ip] Premature end of script headers: script.pl
It’s strange, but anyway it doesn’t works. I spent some time trying to fix it ( some guys recommend to rebuilt suexec – but it’s not a simplest way to fix this problem ) – in my case it was fixed by changing owner of my suexec. I check out current properties :
ls -la /usr/lib/apache2/suexec
-rwsr-xr– 1 root www-data 18872 2009-07-10 18:40 /usr/lib/apache2/suexec
and change them :
chown root:root /usr/lib/apache2/suexec
chmod 4755 /usr/lib/apache2/suexec
And don’t forget to restart :
/etc/init.d/apache2 restart
ps. by the way suexec’s id’s are :
#id www-user
uid=1000(www-user) gid=109(www-group) groups=109(www-group)

Microsoft is offering about 20,000 lines of its own device drivers to the Linux kernel that will enable Linux to run as a guest on its Hyper-V virtualization technology. Specifically, the contributed loadable kernel modules enable Linux to run in ‘enlightened mode’, giving it efficiencies equivalent to a Windows virtual machine running on Hyper-V.
