We don't have a role for pure Rust development but I'd be interested to meet somebody with C++ plus Rust, or Python plus Rust. Maven primarily uses C++, C# and Python, but we've recently started using Rust on a couple of projects.

timrobinson | 10 years ago | on: Excel_to_code – Converts some Excel spreadsheets to C

It's absolutely not. Everything I've seen has been 64-bit double. If you need to, you round either intermediate or final calcs to a set precision.

I once worked on replicating a particular index, and the engine used fixed point internally. In order to get the values to match with the ones published officially, we had to emulate Excel floating point: our fixed point values wouldn't line up with theirs.

timrobinson | 13 years ago | on: Cmd - A saner way to running external programs from C#

It won't hang as long as you're redirecting only standard output. If you want to read both StandardOutput and StandardError, you need to do it from separate threads: either with explicit BeginInvoke/EndInvoke calls as in Kudu, or more simply, by listening on the OutputDataReceived/ErrorDataReceived events then calling BeginOutputReadLine/BeginErrorReadLine.

(The reason for this is that the two streams are redirected to separate pipes, each of which has its own fixed-size buffer. If you forget to read from one pipe while you read from the other, its buffer fills up, and the writer - the program being executed - blocks. With standard error redirection turned off, the program writes directly to the console, which is safe.)

timrobinson | 13 years ago | on: Telling people to leave finance

I think this is a little too cynical. I've seen elements of what you describe in previous jobs, but never all at the same time, and never to the same extent.

Then again, the culture and the work varies in different cities and in different roles. In London we tend to get excellent developers joining the industry (traditionally there hasn't been much else for good developers locally) so you can typically expect to have skilled colleagues. And the closer you get to the front office, the more money there is for IT projects, and the more remit you have for writing good software.

timrobinson | 13 years ago | on: Command line tools every web dev needs to know

If typing is hard then you're less likely to go back over your code and correct typos and minor errors. At any rate, hunt-and-peck typists tend not to spend time going back over the code and formatting it nicely.

timrobinson | 13 years ago | on: RBS IT cockup: This sort of thing can destroy a bank, normally

If it's true that this is a manual error, then I have two questions:

1) Why did it take until the early hours of Wednesday to find out? Why not run a manual check after the change went in?

2) If they found out on Wednesday morning, why did it take until Friday - after three failed batch runs - to fix it?
