I mean sure, if you think IDEs are just slow, expensive text editors with fewer keyboard shortcuts, then you'll be disappointed, but features like "navigate to any symbol by prefix", "find all usages", and "Ctrl-click to navigate to def…
Do you have links to these studies available? My experiences support your claims, but I'd be interested in getting my hands on some objective data.
Note some of the Java solutions were over 40 hours, and many are over 8 (one working day)
The version I saw was informal, and included F# and C#. I remember that F# was roughly twice as fast as C#.
I don't know F# but a friend of mine does, and we both solved the sample problem. He did it in under half an hour. It took me just over an hour, but I could have done it in about 45 minutes easily except that I had (embarrassingly) misread the problem statement and wasted a bit of time.
I used Visual Studio's debugger twice, and that did actually help a lot to get the problem solved quickly.
People who are really good at Vim and C remind me of someone who is really good at using a shovel. As impressive it is to watch them work, they can't compete with a backhoe.
