Why ?

'Why' is either a complete loon or an utter genius.

In addition to writing Whys (Poignant) Guide to Ruby he has recently created Hobix which is a Ruby based weblog engine. Hobix seems to borrow heavily from the Keep It Simple Stupid philosphy of Blosxom with a few wonderful twists (your weblog is referred to as a 'blahhg'). Nice to see someone has a sense of humour about this type of thing.

A couple of cool Wiki tools that require minimal skills to get up and running

  • Ruby based Instiki. Instiki is completely selfcontained and doesn't need apache or sql to serve or backend the wiki - you just need Ruby installed.
  • Self contained CSS/Javascript Tiddlywiki.

A timely howto - Using SSH and RSYNC to backup data across a network.

Engadget are running a great little article on how to setup your Mac or PC to act as a simple home-security system using a webcam. Its actually a little disappointing how hard something like this is to implement - why do many webcam server implement email, streaming and ftp but no support for secure copy or ftp and they often have a really lacklustre html gallery feature.

A colleague implemented something similar to this and it was amazing to behold - sortable html tables.

GFI Mail Archiver

Slightly Bigbrother-esque but I can see many organisations needing this level of accessible transparency - GFI Mail Archiver. Essentially archives all email sent and received to an Exchange server in an SQL database and makes it accessible via a web interface.

Another windows freeware site - Portable Freeware - with a focus on software that doesn't need to be installed or can be installed and then safely moved somewhere else and run (eg a c:\bin directory for small tools). The best tool on this page has to be Wink which lets you create shockwave movies from screen captures - note that vnc2swf does a similar thing for Unix.

Great advice on How to Pitch an Idea.

This site uses blosxom version 2 with the following plugins blox, breadcrumbs, calendar, categorytree, flatarchives and state.

Blosxom is a simple perl script that works in conjunction with your web server - essentially each post is a seperate text file which you place in directory and that gets served up according to some simple rules that can be configured in Blosxom itself. Folders for posts represent categories, plugins provide extra features and flavours allow you to customise the look and feel of the site. Blosxom also automatically generates an RSS/XML feed from your posts making it easy to subscribe to updates in a feed-reader.

I've just discovered blosedit for web based editing although I also use the Mac OS X app blapp and of course ssh / vi.

AIX Logical Volume Manager

Allocating disk space on an IBM AIX machine

In this example we'll be increasing the amount of /tmp space available.

You can use a Calculator to fine tune the allocation process (you don't accidentally want to allocate all the remaining space to a file system so start conservatively and increase file system size on request) but this example uses basic approximation.

I'm sure theres a much simpler way to do this for serious AIX types but if you're a 'dabbler' then this process works for me.

Disk Space Before

bash-2.00# df -k /tmp

Filesystem 1024-blocks Free %Used Iused %Iused Mounted on

/dev/hd3 196608 172020 13% 256 1% /tmp


1. Login

2. Depending on your terminal emulation you may want to issue a TERM=vt100 (or similar) so SMIT (IBM System Management Utility) works properly in text mode

3. Start smit - the important keys that you will use are F3 to Cancel an Operation and F4 to List Options; arrow keys will allow you to move up and down through menu options - if you find that the function keys don't work, use esc- sequences instead.

4. Select System Storage Management

5. First we need to allocate more LP's (logical partitions) to the /tmp filesystem

a) Logical Volume Manager

b) Set Characteristics of a Logical Volume

c) Increase the Size of a Logical Volume

d) Hit F4 to list the Volumes and select /tmp

e) Bump up the Number of Additional logical partitions

f) Hit Enter to commit and action the changes - you should get a Command: OK

6. Increase the actual partition size

Hit F3 to escape back to the initial System Storage Management screen

a) Select File Systems

b) Select Add / Change / Show / Delete File Systems

c) Select JFS (unless you know the file system has a different format)

d) Change / Show Characteristics of a JFS You should get a pop up list of available file systems; select /tmp

e) Bump up the Size of file system

f) Hit Enter to commit and action the changes; you should see a Command: OK and the new file system size

Disk Space After

bash-2.00# df -k /tmp

Filesystem 1024-blocks Free %Used Iused %Iused Mounted on

/dev/hd3 262144 235496 11% 256 1% /tmp
