Not really. Calling a C++ template-generated function is no different than calling a C function. If you have a lot of tiny template-generated functions then sure, it would be slow.…

Minnesota does a significant amount of research on road surface materials. There is a section of I94 northwest of the Twin Cities that has three segments of highway, and traffic ca…

I grew up in MN and always loved Honeycrisp, but after relocating I was surprised to hear people describe them as tasteless or mealy. It turns out they vary a lot depending on grow…

I just closed my account. Unfortunately, this requires sending an email to support@uber.com. It's inconvenient, but gives you a place to explain that you will not use the service u…

The "six distinct features of a functional language" are misleading/inaccurate: 1. Laziness: Not required. See Lisp, Scheme, ML, OCaml, etc. 2. Functions as first-class citizens: T…

There are quite a few extra issues that come up when you implement a usable allocator. I'm surprised the article didn't mention them. Here are just a few: Alignment: different syst…

There is no "killer input" for randomized quicksort. I'm surprised libc doesn't select pivots randomly already.

It's not just a shuffled heap, it's also sparse. Section 4.1 covers heap overflow attacks, with an attacker using overflows from one object to overwrite entries in a nearby object'…

You could do better with a probabilistically secure allocator instead: http://people.cs.umass.edu/~emery/pubs/ccs03-novark.pdf Randomized allocation makes it nearly impossible to f…

Daniel claims that volatility is actually lower with HFT when you look at implied volatility, a predictive measure of volatility. Lewis uses actual historical volatility in his arg…

Why? I see no problem with a position of "this is bad." And since this is a discussion about a book, it's worth pointing out that the book is focused around an alternative proposal…

Little's law certainly applies here. The article's author does have a good point though: if there is no queue and requests are processed one by one, your only option is good old se…

The Mall of America, from the same developers as the West Edmonton Mall, is another good exception. The mall is massive, but the interior spaces feel like the outdoors. This is par…

No. The clocks use the local Date object, but the rotation calculations for hour hand were copied over from a 12 hour clock. One downside of 24 hour clocks: a broken one is only ri…

Looks nice, but the hour hand is wrong on all the 24 hour clocks.
