Multiple library versions

Working with vendor code in C can get very tricky, especially when you except breaking changes to occur. Especially when you have multiple binaries depending on that vendor code, updating at different times, necessitating different live versions. Let’s explore. Introduction Assume you’re working with an external vendor, who is providing you with code for a wonderful function getFoo: // foo.h version 1.2.3 int getFoo(); // foo.c version 1.2.3 int getFoo() { sleep(1000); // TODO improve performance return 42 } You use this function in many of your products - for example, in your best-selling barApp application:...

Reading, writing and vacations

Vacations are a great time for doing that problematic category of things every management course teaches you about: important, but not urgent.

I’ve already mentioned my show downloading stack on this blog. It’s changed a bit since - I now use Transmission rather than rtorrent, as it has the excellent transmission-daemon package which has it acting exactly the way I like (without using screen). Also, it now E-mails me when a torrent is done downloading. So while this may be how TV works for you: Notice that a new episode is out Torrent it Wait for the download to finish Watch it …this is how TV works for me now:...

Developing TransportDroidIL for Android

Here are a few words on developing TransportDroidIL, a small utility to query Israeli public transportation sites more easily using an Android phone. Source control is super important. Mistakes will be made, other coders will want to join in, and experimental features will want to be in their own branches. Git is awesome; it does source control right, gives me powerful tools, and isn’t a hassle to set up - even for a small project like this....
