If it doesn't interact with gas clouds how do you build an efficient detector to receive it?

Well, the confusion sure seems intentional. "On July 15, 2015, the creator of Redis and lead developer, Salvatore Sanfilippo, joined Redis Labs to lead open source development, and Redis Labs became the official sponsor of the open sou

Right. One technique used for writing games to run on GC'd runtimes is to avoid allocations entirely in the game loop. With a lot of work, you can preallocate everything you're going to need and just modify it as you run. This tec

Games are all about keeping the user in the 'flow'. Humans are really good at picking up on unpredictable timing. Action games are thus fundamentally hard-real-time systems.

To be precise, the term 'fake news' is an accusation against the media, used as a propaganda tactic, and most often false.

Tide pods are not actively marketed as toys, they are indeed marketed as household chemicals. I agree CPSC should not be able to ban the sale of magnets in general, but it seems reasonable to me that they be able regulate how products are m

If the standard says a message can be up to 4096 bytes long, but for 15 years the message in practice is always under 250 bytes, there are going to be some implementations that just use a fixed size buffer smaller than 4096 bytes.

Never expect old code to handle new protocol elements. If it's not exercised regularly, it's not going to work. Very few developers (outside of Google) are going to write randomized fuzzers to test for compatibility with theoretic

But that's how we do it now. It's just that Optane persistent storage is attached to a different bus with much better latency and throughput. Probably categorically and disruptively better. How will user-mode applications refer to

We need reviewers report a new metric: time to failure at continuous max write throughput. For some SSDs, it's under a week.

There are only two types of time systems: 1. TAI, and systems that have a fixed 1-to-1 mapping to it (e.g., GPS). 2. Systems that are generally unable to calculate how many seconds will elapse until your next birthday. UTC is in this cate

Angular momentum increases linearly with mass but with the square of the radius. So another key solution to capacity is to increase the size of the flywheel. Obviously there are real limits to this in a car.

Good point, but I didn't mean to sound specific to testing apps. I just meant, in general, write big apps using Python top-down and something precompiled if you must spawn lots of external processes.
