It makes me sad whenever I hear about indie developers feeling oppressed by customer support, which ought to be source of ideas for improving the product rather than a drag on development. In my mind that's actually what sets indie pro

I met David at JuliaCon a couple weeks ago -- he's a physics professor at the National University of Mexico and a charming interlocutor. I haven't made it through this (4-hour) tutorial myself, but the word among the core develope

I would also like to see such a community. I've found it somewhat in the Julia community, which tends to lean heavily towards scientific computing and has a lot of Ph.D.s, grad students, and Ph.D. dropouts. We just had JuliaCon last we

I occasionally receive emails like these, and I agree with most of this advice. I will add a couple of personal turn-offs: * Overtesting. I have received multiple emails from different people at the same company with the exact same subject

Dig deeper, Sam. Achievement-oriented people are given to depression both when they fail and when they succeed. If your identity is tied up in your work, then you feel bad about yourself when work isn't going well. That's obvious,

I'm pretty sure this formula is correct, but I haven't seen it published anywhere. John Cook has some veiled references to a closed-form solution when one of the parameters is an integer: http://www.mdanderson.org/

This is a good discussion, but the author is confused about what the "Low Base Rate Problem" is. It doesn't have anything to do with the null hypothesis being true most of the time -- the example the author gives is actually

We'll definitely record the talks and post them online -- but whether we'll have live-streaming is TBD.

JuliaCon's been in the works for a while now. I'm helping organize it, feel free to leave any questions here and I'll try to give you a prompt response.

Thanks for sharing your work. I love your approach to showing relationships inside a spreadsheet. This is definitely a feature that Excel ought to have, which is both good news and bad news for your business. The good news is that you'

This has been a knock-down drag-out fight and a lot of fun to watch. VW hates the UAW, but they can't say as much because being seen as anti-union would hurt their image back in Germany. Thanks to NRLB rules, VW can't make any sta

Braintree is a Chicago company. Adrian Holovaty (of Django fame) recently caused a stir here when he argued in front of a group of investors that Chicago is an ideal place for bootstrappers: http://www.holovaty.com/writing&#

I've enjoyed watching the "arc" of GraphSketcher. I went to college with the original developer, who, upon being sufficiently annoyed with having to draw supply and demand curves by hand in Econ 101, wrote the code that event

I won't comment on the virtues of bandit algorithms, but the author grossly mischaracterizes the requirements of a multivariate A/B test. Just do a regular 50/50 split and run a regression on the outcome using the observable

I think what the author misses is the large institutional structure that restricts the supply of experts and (as a result) enhances their prestige. These days, with the growing availability of technical information, existing systems of lice

I'd just like to add that what I love about Julia is that it actually lets you go deeper than C code. For high-performance computing it's easy to hit a wall with C (i.e. with SIMD vector instructions), and it's fairly diffi

I have to challenge the premise that most of the responders have taken, which is that working on a daily schedule is "better". On the contrary, I find that my work habits are a lot like yours -- and I think that's a good thin

The Erlang VM is a successful implementation of N:M. It addresses some but not all of the issues you mentioned. * IIRC each new process consumes 284 bytes so it's not "spending lots of memory on creating stacks for your green thre

I like Julia because in many ways, it's a better C than C: * You can inspect a function's generated LLVM or (x86, ARM) assembly code from the REPL. (code_llvm or code_native) * You can interface with C libraries without writing an

A "50/50" rule such as the one described is a clear signal that the memory manager's cache eviction policy is an ad-hoc hack. This sort of problem would benefit from some old-fashioned operations research-style statistic
