smbpasswd -r YOUR.DOMAIN.COM -U YOUR_USERNAME

This will mean you don’t need to find a windows box every time your password expires if you only use say Outlook webmail in a windows environment.

nslookup -type=srv _ldap._tcp.dc._msdcs.YOUR.DOMAIN.COM

I was creating a Jar via the Java API’s and I couldn’t get it to run my main class:

 $ java -jar foo.jar
Error: Invalid or corrupt jarfile foo.jar

Running it via the class path worked fine:

 $ java -cp foo.jar Bar
Hello world!

So now I knew it was something to do with the manifest file but it wasn’t being caused by

• The 65535 file limit (See Zip64 and Java 7 ).
• The 72 bytes limit per line
• Missing newline at the end of the Main-Class (Displays “no main manifest attribute, in foo.jar”
• A blank line before Main-Class (Displays “Error: An unexpected error occurred while trying to open file foo.jar”

So after scratching my head for a while I tried comparing a working jar with the failing jar:

left (Ctrl+Super+Left):

wmctrl -r :ACTIVE: -e 0,0,0,1280,1032

right (Ctrl+Super+Right):

wmctrl -r :ACTIVE: -e 0,1280,0,1280,1032

My .gitconfig contains

[user]
        email = dan@bodar.com
        name = Daniel Worthington-Bodart
[color]
        ui = true
[alias]
        ci = commit
        co = checkout
        st = status -sb
        nuke = !git checkout -f && git clean -f -d
[push]
        default = current

Nat Pryce pointed out these gems:

Scala Reference 6.12.3

Precedence:
“The precedence of an infix operator is determined by the operator’s first character.”

Associativity
“The associativity of an operator is determined by the operator’s last character”

This actually made me cry.

As I got quoted recently in “Scala — 1★ Would Not Program Again” I though I finally should write up a little Wat moment we had recently:

So does anyone know “wat” the following Scala code returns? (Value and Type)

List(1,2,3).toSet()

A Set<Int> containing 1,2,3?

Nope how about I give you a clue, there are 2 bugs in this one line:

1. A type inferencing bug where it chooses Set<Any>
2. A bug where the brackets are used for both calling the Set.apply method and constructing Unit, notice there no space between the “toSet” and “()”

Yup you guessed it, it returns:

dconf reset -f /org/gnome/gnome-panel/
killall gnome-panel

An alternative approach to just doing CSV export (which is fast and more cross platform/app) is to use web queries (.iqy files that point to fairly HTML) or data queries (.dqy extension but point to the DB)

Pro

• Supports refreshing data / live data model
• Web based integration
• Very easy to do
• Works with all versions since excel 97
• They support linking back into you app via urls (IQY only) so we had cells that said edit that took you back to the web app.
• Auto sorting, pivoting is a doddle

Cons

echo 'enabled=0' | sudo tee /etc/default/apport
