HP to Contribute webOS to Open Source

Looks like after killing their TouchPad tablet, HP open sources WebOS:

Might mean the TouchPad will make a comback. We'll see.

Review: 1Q84


1Q84
1Q84 by Haruki Murakami

My rating: 5 of 5 stars



I can't quite put my finger on it, but this books keeps reminding me of things I've forgotten or ignored.

I must say I've enjoyed Book 3 the most.

Well, that's it. For now at least - I'm out of Murakami :-(.

Review: Getting Things Done: The Art of Stress-Free Productivity

Getting Things Done: The Art of Stress-Free ProductivityGetting Things Done: The Art of Stress-Free Productivity by David Allen

My rating: 5 of 5 stars

I've been using the methods and techniques described in GTD along side mind mapping in practice for over 8 years (mostly due to tools like OneNote, Emacs ORG mode, XMind/Fremind, etc). Reading this book has definitely helped optimize my workflow and planning into something quite a bit more efficient.

Right now I'm still looking to overhaul my tooling, OneNote isn't available on UNIX-like system (though it mostly works with wine), and Emacs ORG mode isn't practical for pasting images, screenshots, video, audio, files, etc. and such for reference.

It's tried a bunch of Java tools (Thinking Rock and GTD Free) but they're not very good for reference, note taking and reminders / calendar stuff. So far it's proving hard to beat the OneNote + Outlook + Project combo.

One tool I've been using for a while now (probably an year or so) along side OneNote is Tracks . It's a RoR webapp that covers most things in the GTD workflow. Although import/export isn't yet available as of version 2.0, it gets the job done. It's also available from Bitnami as a pre-installed stack.

If you're into GTD or just like to organize yourself with TODOS, tasks, projects and such, Tracks is worth a try.

Convert AWK to Perl using a2p

Automatic conversion of AWK scripts to perl.

A little awk script that numbers lines:
ls -la /usr | ./linum.pl
1 : total 240
2 : drwxr-xr-x+ 12 root root 4096 2010-06-21 06:47 .
3 : drwxr-xr-x 22 root root 4096 2011-05-11 12:06 ..
4 : drwxr-xr-x+ 2 root root 69632 2011-05-24 14:07 bin
5 : drwxr-xr-x+ 2 root root 4096 2010-05-05 11:33 games
6 : drwxr-xr-x+ 5 root root 4096 2010-06-21 06:47 i586-suse-linux
7 : drwxr-xr-x+ 52 root root 4096 2011-05-13 04:17 include
8 : drwxr-xr-x+ 156 root root 69632 2011-05-24 14:07 lib
9 : drwxr-xr-x+ 10 root root 4096 2010-06-21 06:47 local
10 : drwxr-xr-x+ 2 root root 12288 2011-05-24 14:07 sbin
11 : drwxr-xr-x+ 213 root root 4096 2011-05-23 13:19 share
Let's convert this to perl using a2p.
echo '{ printf("%5d : %s\n", NR, $0) }' | a2p > linum.pl
chmod +x linum.pl
Let's try it out:
ls -la /usr | ./linum.pl
1 : total 240
2 : drwxr-xr-x+ 12 root root 4096 2010-06-21 06:47 .
3 : drwxr-xr-x 22 root root 4096 2011-05-11 12:06 ..
4 : drwxr-xr-x+ 2 root root 69632 2011-05-24 14:07 bin
5 : drwxr-xr-x+ 2 root root 4096 2010-05-05 11:33 games
6 : drwxr-xr-x+ 5 root root 4096 2010-06-21 06:47 i586-suse-linux
7 : drwxr-xr-x+ 52 root root 4096 2011-05-13 04:17 include
8 : drwxr-xr-x+ 156 root root 69632 2011-05-24 14:07 lib
9 : drwxr-xr-x+ 10 root root 4096 2010-06-21 06:47 local
10 : drwxr-xr-x+ 2 root root 12288 2011-05-24 14:07 sbin
11 : drwxr-xr-x+ 213 root root 4096 2011-05-23 13:19 share


The code block looks pretty good:

while (<>) {
chomp; # strip record separator
printf "%5d : %s\n", $., $_;
}

NSA Operating Systems Security Configuration Guides

NSA published some rather interesting OS security guides:
http://www.nsa.gov/ia/guidance/security_configuration_guides/operating_systems.shtml

The RHEL Security Guides are quite good.

I've used these along with the Security Guide and the Security-Enhanced Linux guides from RHEL.

IBM SmartCloud Enterprise tips: LVM and FTPS

IBM SmartCloud Enterprise tips:

Learn how to set up a 64-bit Linux® instance (starting with a Bronze-level offering) with the Linux Logical Volume Manager (LVM), capture a private image and deploy a new instance as a different offering (a Platinum tier) and then grow the LVM volumes and file systems to accommodate the new physical volumes. This article also shows how to configure and manage LVM across physical volumes using Linux LVM-type partitions:


Set up a Microsoft® Windows™ Server 2008 R2 on the IBM Cloud so that it can act as a file server.
