Retry and clear failed Resque jobs
This is for posterity’s sake :)
Retry all jobs:
(Resque::Failure.count-1).downto(0).each { |i|
Resque::Failure.requeue(i)
}
Retry jobs for a particular worker:
(Resque::Failure.count-1).downto(0).each { |i|
payload_class = Resque::Failure.all(i)['payload']['class']
Resque::Failure.requeue(i) if payload_class == 'MyWorker'
}
Clear failed jobs:
Resque::Failure.clear

Performing Disk Repairs on OSX without Install...
I dont travel with my OSX install disk (seriously, who does?) and found myself in a situation where i needed to repair my macbook pro’s hard drive using said installation disk.
There are two options if you find yourself in a similar position:
Start in safe mode: Hold shift down during start up (performs a simple disk scan)
Start in single user mode and run fsck: hold down command+s...

All my backups are the same size?
I recently noticed that the database backups of an app. that i maintain were the same size for a couple of days.
Now, all the backups are done from a MySQL slave database, so it didn’t take too long for me to work out that my slave had died; running “show slave status\G” yielded something like this:
....
Slave_IO_Running: Yes
Slave_SQL_Running: No

Cheaper to fly to NY and buy a Macbook Pro?!?!?
I was a little surprised recently when i priced buying a new 17” Macbook Pro from local South African Mac suppliers. I discovered that it was cheaper to buy a return ticket to NY and buy the machine there, than it currently is to buy it here in South Africa.
Here are the numbers for flying to New York:
R8,909.00 -> Return flight from Johannesburg to JFK in New York
R23,791.50 ->...
Merb web service with Shoes GUI
Every couple of months I play around with shoes to try and solve some basic prototyping needs that arise at work.
This time round i stumbled onto a nice O’Reilly tutorial that shows you how to setup a basic merb web service and interact with it using shoes. Well worth checking out.

BuddyPress 404 errors on Blogs, Members, Groups
I ran into a bit of an issue trying to get BuddyPress setup on my Mac (Tiger, if you must know) - clicking on Blog, Members or Groups would yield a 404.
To fix the problem you need to add the following (in addition to what is explained in the various readme files) directive to your httpd.conf:

Thoughts on hiring freelancers
Hiring freelance developers has come into the spot-light for me recently and i’ve been trying to work out how one attracts the best candidates.
I’ve recently been involved with posting a WordPress job on oDesk, and the candidates that applied have been very interesting - their skills tend to reflect a singular methodology or paradigm: the skills they list all reflect the same kinds...

Net::SMTPSyntaxError: 501 Invalid characters...
So, you’re using ActionMailer and you get an icredibly funky error when trying to send mails - something like this:
Net::SMTPSyntaxError: 501 Invalid characters detected
Round about now is when you start thinking about that career in advertising you passed up when you look at your environment.rb file, which contains something like this:
ActionMailer::Base.delivery_method = :smtp...
Nothing speaks louder than code
Jumping to conclusions and dealing in “what-if” scenarios without investigation is a form of time compound interest: vast armies of time is sucked into a vortex of nothingness.
If you dont like something, don’t moan about it! Implement something you think is better and campare from there!

Git the --hard way
Let’s pretend you just successfully commited your latest work to GitHub. All’s fine.
Now let’s pretend that you accidentally ran “rm *” in your project directory. No problem: just run:
git reset —hard
All the changes you made since your last successful commit will be discarded and your deleted files will magically reappear.

Read other people's code
The best way to improve yourself as a human being is to absorb the insights of others.
Specifically for programming - read other people’s code!
I stumled across this nifty little method “all?” examining some FactoryGirl examples:
%w{ ant bear cat}.all? {|word| word.length >= 3} #=> true %w{ ant bear cat}.all? {|word| word.length >= 4} #=> false [ nil, true, 99...
