I have similar remarks. On OSX, the tab and the url bars are too big, they seem out of place.. Also, the black tab bar seems strange to me as I have a black OSX menu bar..

For me it was information overload. Not that I care what my neighbour ate for lunch yesterday, but don't throw it in my face. I thought that such stupid information would be innocuous, and in a sense it is, but as they say, ignorance i

Thanks for your input, I briefly checked those links and they seem to be stores and quite overwhelming in their range of products and tutorials. What I'm looking for is mostly project tutorials or books at a basic level, as in "ho

Maybe is not the best topic to ask, but does anyone know good sources (websites, books, kits) for playing with and learning a bit more about microcontrollers and electronics? I would prefer structured sources (those that take newbies by han

Well, where I took my PhD degree (I'm not in the US), I was the only one working on Text-mining and Information Retrieval (besides my professor), and I think there was only three or four other PhD students working on AI - one on SOM (S

I also recommend Java Spark for a minimalist framework. I would say that is quite similar to Flask in Python. But unlike Flask, Spark does not have a templating language. FOr something simple, I would recommend freemarker..

As a CS professor, I have to create lots of exercises for my students so I keep my brain occupied with these kind of things, trying to simplify my examples on each iteration. I find that it is very hard but very gratifying to simplify thing

> Also, where's the check whether `i` is actually prime before you start crossing of multiples? You don't need to cross off multiples of composite numbers. You are absolutely right as the original method seems to specify that.

There's a small optimization on the original article which I think your implementation doesn't do: "At each stage we know that every composite number up to p^2 has definitely been marked as such".. Assuming your implemen

Any suggestions on how an arrangement like that could work out for you, like weekly 1-hour online meetings for instance? Just trying to gather some generic opinions, aka "testing the market" :)

An alternative to the books and links posted here could be to find someone who can help you with your "basic" CS doubts? Kind of a hire-a-CS-tutor, who could provide you with the necessary information, teach you something and even

If AI == Neural Networks only, maybe matrix knowledge is enough, but when you start to include NLP, Expert systems, SEarch algorithms such as A*, Minimax, etc. in the AI category, you'll have to know more mathematics.. AI is much more
