SQL Server Express is the free edition of Microsoft’s excellent database server. Understandably, Microsoft chose to cripple the free version to create some differentiation between product tiers.
There’s one cripple, however, that makes no sense to me. Microsoft chose to disallow the use of ALTER TABLE statements. But why block these statements when the workaround is so simple…
Robot Turtles is a game designed to teach programming fundamentals to young children. I purchased a copy through the Kickstarter launch and have been playing it since with my four-year old son. He loves the game and quickly unlocked all the levels up to “Play 3.”
At the same time, I’ve been intending to learn F# for a while…
I had to write some code recently that opens a .tar.bz2 file, modifies the contents, and then repackages back into a .tar.bz2. The fun and games ended when I discovered this obscure showstopper: ICSharpCode.SharpZipLib.Tar.TarException: Header checksum is invalid.
The following is an account of how I got here and my thought process while solving the problem.
Don’t Repeat Yourself is a well-known Computer Science adage. Sometimes, however, it’s too convenient to just repeat some code now and deal with it later. But eventually that practice will cost you. Maintaining multiple copies of code becomes a nightmare when a bug needs to be fixed or new features need to be added. It’s especially bad when many people are working on the code and don’t realize other copies exist elsewhere. Ugh.
I fell in love with Photography a few years ago. Shortly after that I found that Canon’s suite of tools (primarily Digital Photo Professional) was absolutely terrible for editing and managing photos.
I briefly used (and loved) Picasa for it’s organization capabilities (geo-, keyword- and face-tagging en masse). But Picasa–at the time, anyways–was very weak on editing capabilities. A friend recommended Lightroom 3 and I haven’t looked back since (I’m now on v4.4).
Lightroom isn’t perfect, however. It has a few usability issues. One of my pet peeves is that Lightroom for Windows doesn’t support the mouse wheel. I’ll reflexively scroll down… but nothing happens. This drive me crazy.
