TR plugs are required now in the US. We replaced ours because it looks a lot better than outlet covers.

Also we know that pre-teens are more than twice as sensitive to light as people in their late teens [1], and CRTs were 9300K also [2], though they were quite a bit dimmer than current ones. 1. https://academic.oup.com/jcem&#

How do you determine "whether they were senior or junior faculty" from anonymized data?

Actually, there is only an advantage to radix after 100,000 elements - djb is much faster for small arrays. Also, while radix is cpu constant time, you'd need to do some kind of secure shuffle in advance to make it truly constant-time

My single-threaded floating point sort is also twice as fast as djbsort: http://stereopsis.com/radix.html This one uses 11-bit radix to save memory bandwidth. Without all the floating-point stuff it would be faster.

Amazing that Net Neutrality can be bought for only $60,000. Wikipedia says: "State Assemblyman Miguel Santiago received over $60,000 from telecom lobbyists, with AT&T being the top telecom contributor, over the course of his assemb

In case anyone else was confused by a 200KB file taking so long, the original file is 9933x7016 (7.1MB) and actually does take that long. I'm not going to link it here because the site already seems slow, but it is easy to find if yo

I have lots of forceinline and always_inline in my code, but you can do too much of it, so always benchmark to be sure.

Graph says pretty clearly the patch is 60-70% slower! or 2.5-3x hardware costs. I wonder which CPU family this is?

This seems complicated, but my impression is it would mean: a) a super-smart compiler that can anticipate lots of flaws and fence them or turn on restrictive modes (maybe V8 is this smart?) b) you have to turn off more speculation than you

It's kind of amazing in the browser (both Chrome and Edge, not Firefox). For regular apps it doesn't matter as much.

What if the flaw was earlier in the design? The iPhone has a battery that's 2/3 the size of other phone batteries. Would there even be a problem with a 1000mAh bigger battery?

Identity is super hard to export and it always has been. There are privacy issues: do you disclose email addresses to establish identity? Imagine exporting a Facebook group, it is incredibly hard to do.

SynTP.sys is signed by Synaptics on my Thinkpad. Why is this HP-specific?

I think most six year olds should not have phones. But am happy with Apple's "find my friends" in that case.

Once an hour GPS (as I suggested) is not the same as "privacy", and yes if the adults trusted with care of a six year old take them somewhere unexpected for a long time, the parents should be able to find out. You could claim this

I think this bias needs to evolve, and maybe birth year is more descriptive than age. In 2000, a 40 year old was born in 1960, when the home PC was nearly 20 years off. A programmer who is 40 today was born in 1977, and they could learn to

Young kids (who should rarely be own their own) are different than teenagers.

If your young child gets lost, why is a watch that reports GPS once an hour a bad thing? This is very different than spying on a teacher or recording audio.

This is also a business model problem. Consumer hardware companies do not have the margin to make and support software that needs to run for ten years or more. Before the iPhone, software and hardware were often different and had different

You can use sigcheck -tv (sysinternals) to test against Microsoft's list. I prefer RCC (root certificate checker) and have used it in the past, but the website seems to be suspended.

We wondered this too - we surveyed people who were installing f.lux for the first time about what they cared about - "eyestrain vs. sleep". 90% of people said better sleep, 60% said eyestrain. So both are important. But imagine yo

Hi everyone--developer of f.lux here. I wanted to say that we stopped thinking of f.lux as a way to match a room about 8 years ago. We have been consumed with the idea that if the human circadian system is controlled by light, and if nobody

RAM per connection is quite big with HAProxy, so if you're simply load-balancing lots of connections, something like nginx has a smaller footprint.
