Almost all of what you said applies equally to Python when using NumPy, Pandas, and SciPy. In R, a Factor is also the bizarre result you get if you load a flat file incorrectly. Lots of things in R proceed without stopping on errors, and yo

This is true in theory but not in practice. For example, NASDAQ OUCH, which is one of the most popular protocols for entering stock orders in the world, has a maximum price of 199,999. A stock trading at one dollar can go up by a factor of

Last time I tried it, that GCC attribute was only implemented for C, not C++. It seems like a good idea anyway.

The source control system is like an attic (some even use that term). Commenting out code is more like leaving those dusty boxes in the dining room. I suppose one little old box might be ok if it has sentimental value.

The complaint that the server side of web sockets requires using epoll is strange. Of course we have known for years that select has scalability problems, but we have moved on. That this implementer says they normally use select in 2015 for

Speaking as someone whose coworker once stole our code, I predict the biggest loser in this event aside from the thief will be the employees. Imagine working at Yandex now. Everything is going to get scrutinized and locked down until people

A 20x speedup as reported here is not that unusual in my experience. If I work on optimizing something which has never had detailed performance analysis, I expect to achieve 3x to 10x speedups in most cases. Even 100x is not really rare. I

In England you don't have malaria or dengue. But if you did the council would forbid you from doing anything about it, because hey, mosquito borne disease is historic.

Arista does run software on their switches. But that is the supervisor, aka the control plane. The data plane, where the actual throughput is achieved, is done with ASICs, and in some cases where user programmability is needed, FPGAs. At no

I would add one question for the prospective customer of such an appliance: why do you need it? Why do you need an appliance analyzing all your network traffic in real time? And if you truly do need such an appliance, why does it need to b

Conceptually, dereferencing a pointer then taking the address of the result is a no-op, you get back what you put in. There's no requirement for dereferencing a null pointer to segfault, only an expectation of many modern commodity-

This doesn't explain NYC, where a huge number of apartments use window units. Landlords don't feel compelled to provide A/C, so tenants need to provide their own, but tenants aren't allowed to drill any holes at all, so

One of the culprits: > air-conditioning units (which are basically unrestricted openings to the street) Window air conditioning units are virtually unknown in a large part of the warm weather world. We use "split systems," whe

I haven't used OpenCL before. This library seemed sort of reasonable but I had some questions about whether it was really that much better than the native OpenCL API. So I found an OpenCL "hello world" program here: http:&

Fine-grained trade data is almost always charged. Exchanges charge their clients to get data directly, and they charge multiples as much to those clients like Bloomberg who wish to redistribute the same data. This is not really surprising

I went about it the opposite way, and can definitely recommend that as well: big company first, then small. The big company experience shows you a ton of things, like how to interview, build, and deploy at scale. The small company can ben

Fun cultural note for those reading this who may not know: a "lakh" is just 100,000 of anything, in India, Sri Lanka, and Nepal. People do not speak or think in terms of "millions" regardless of the magnitude, it would

Given that in the US there is literally no level of safety which will satisfy even 90% of people, it's useful to have a bite-size entrant who can move fast and fail if needed.

This piece is really well written in an accessible style. It's even more clear than the original article, and does a great job of sounding genuinely kind to all parties (except maybe the journalist, who will be prepared for it). Well d

You're assuming a constant arrival rate and zero overhead. Both of which are definitely not accurate. As a wild guess, you're off by 1000x. You may say 400MBps is still not too crazy, but it's beyond the real capacity of many

There is no such thing as a Brazilian green card. Green card is a figure of speech that is mostly used to refer to US permanent residency. Other countries often just call it PR.

Solaris, an otherwise good quality enterprise operating system, had an 8-character limit just like that for decades. They only fixed it in the default configuration maybe five years ago. You can read about it here: http://blog.
