Tcpdump Light-weight Alternative to Wireshark

Published at 17 January 2012 ·  2 min read

This is a lost post from my early blogs around 2012, rediscovered and posted here in mid-2020 I went to install Wireshark this morning and realised why I hadn’t bothered before. The source code is 20MB [^footnote]. God knows how long that will take to compile, especially since it seems to use autoconf and generates complex, multi-nested Makefiles many levels deep. I already had tcpdump installed, so I used that instead....

Calcc, A Programmers’ Calculator

Published at 16 January 2012 ·  1 min read

This is a lost post from my early blogs around 2012, rediscovered and posted here in mid-2020 I have been looking for a command-line programmers’ calculator for a while. I needed it to do the usual things like base number conversion, bit shifting and masking, and so on. I searched for quite a while and couldn’t find anything. Almost all were GUI, which I didn’t want, or were some ridiculous price, which I couldn’t justify being a programmer myself....

Vi Developed for Slow 300 baud Connections

Published at 6 January 2012 ·  1 min read

This is a lost post from my early blogs around 2012, rediscovered and posted here in mid-2020 Interesting discussion on Hacker News about an interview with Bill Joy, creator of Vi.

That meant the editor had to be efficient in screen repaints while interacting with commands from the user....

Highest Australian Scores in Test Cricket

Published at 5 January 2012 ·  1 min read

This is a lost post from my early blogs around 2012, rediscovered and posted here in mid-2020 With India playing Australia at Sydney right now, and captain Michael Clarke on 325, I thought it would be interesting to look at the top ten Australian scores of all time (which Channel Nine has conveniently provided for us viewers). Matthew Hayden is highest at 380, then Don Bradman at 334 (Leeds in 1930)....

Rails Tutorial

Published at 28 December 2011 ·  1 min read

This is a lost post from my early blogs around 2012, rediscovered and posted here in mid-2020 Spent the last day or two doing Michael Hartl’s excellent Ruby on Rails tutorial. I had a vague idea I wanted to learn Ruby, but once I googled for tutorials it became pretty clear that Rails was the way to go for web-based apps. Michael’s tutorial got lots of recommendations, so I jumped right in....
