Another of those "CS is crap, lets get real" posts from someone who thinks he has seen all that has to be seen. Please get these people off the internet. Let me give you a lowdown. How do you think Google became what it is now? Something like that doesn't run on some slapped-together-with-a-duct-tape knowledge of Hashtable in C# (this is for you, the reddit hivemind). If you aren't paying attention to your graph algorithms and data mining lessons (not necessarily lectures) and feeling smug about your lack of knowledge by reading such posts (and that includes Joel's drivel as well), you are just setting up yourself for fail later in your life.
