My rants and raves about life as a coder.
Here is a quick way of detecting if your script is being source as part of a larger script or being executed directly:
#!/bin/sh
[ "$0" = "$(basename $SHELL)" ] && echo "Script is sourced"
And here are some tests:
ralph@goten:bin$ ./sourced.sh
ralph@goten:bin$ bash sourced.sh
ralph@goten:bin$ . sourced.sh
Script is sourced
ralph@goten:bin$ source sourced.sh
Script is sourced
ralph@goten:bin$
I going to outright say it: MySQL Workbench completely sucks. It is a convoluted, complicated, steaming pile of bloated nonsense. It is hard to perform a simple query. Worse, the damn thing keeps crashing. I missed the simplicity of MySQL Query Browser. Yet, Oracle deprecated it a while back and Canonical removed the package in Ubuntu 12.04.
After some searching, I found that Tyler Wagner maintains an APT repository containing MySQL Query Browser ported from Oneiric.
I summarize the installation here:
sudo apt-add-repository 'deb http://www.tolaris.com/apt/ precise main'
wget -q http://www.tolaris.com/apt/tolaris-keyring.gpg -O- | sudo apt-key add -
sudo apt-get update
sudo apt-get install mysql-query-browser
So, a big shout out to Tyler for doing this work!
Edit: You do need to execute sudo apt-get update before install. Thanks, Steve!
When programming Haskell, I usually hack in a GHCi interactive session. So I was surprise when I tried to make a test executable the other day:
ralph@vegeta:~/src/haskell$ ghc --make Hello [1 of 1] Compiling Main ( Hello.hs, Hello.o ) Linking Hello ... /usr/bin/ld: cannot find -lgmp collect2: ld returned 1 exit status
libgmp is a library for arbitrary precision arithmetic, which is something Haskell does well. So, I was surprise that I was getting this message. The obvious solution is install the Ubuntu package for libgmp:
ralph@vegeta:~/src/haskell$ sudo apt-get install libgmp3c2 Reading package lists... Done Building dependency tree Reading state information... Done libgmp3c2 is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 44 not upgraded.
Well that was strange! So, I searched for libgmp on my system:
ralph@vegeta:~/src/haskell$ find /usr/lib/ -name libgmp* /usr/lib/ssl/engines/libgmp.so /usr/lib/libgmp.so.3.5.2 /usr/lib/libgmp.so.3
There is no libgmp.so symlink, so I just created one:
ralph@vegeta:~/src/haskell$ cd /usr/lib ralph@vegeta:/usr/lib$ sudo ln -s libgmp.so.3 libgmp.so
Now everything compiles and links:
ralph@vegeta:~/src/haskell$ ghc --make Hello [1 of 1] Compiling Main ( Hello.hs, Hello.o ) Linking Hello ...
For the longest time, I have always had a goal to be Windows-free. Many people I work with feel that it is pure apostasy, because I have worked in Microsoft shops in the past 10 years or so. But frankly, I am particularly sick of Windows as a whole. If I can still continue doing my work without having Windows on on my HP Pavillion dv9008nr laptop, then I think I am set.
So, I installed Kubuntu 9.04 (Juanty Jackalope) today. It was the most painless installation of Linux that I had… ever. It was even less painful that my initial installation of Ubuntu 8.10 (Intepid Ibex) on the family desktop (recently auto-updated to Jaunty).
My laptop wireless has the ever painful Broadcom chipset, which historically has been a problem on both 32-bit and 64-bit systems. But I found out that they got off their butts and started to provide drivers for Linux. So, after enabling the closed source drivers, my wireless just worked period. There was no manual configuration that I had to do, no driver to look for, and no searching through outdated documentation for clues on configuring everything. Do you have any idea how refreshing that is?
Here are other refreshing things:
So, I look forward to writing more about my experiences on Kubuntu.
