Now we see the real test of whether healthcare.gov has reached the level of consumer tech: Does bug-report-via-top-ranked-HN-comment get anything done?

Guys. You can configure the touch bar thing. Let's give it a try before raging over it? Otherwise this and the other recent HN threads may be this year's version of the famous Slashdot "Apple introduces the iPod" thread

No, they do it all the time, especially for politically-related stories.

I am no friend of Prop 13, but this is spot-on. It goes to show how hard it is to get the "right" economic incentives, and particular how f*ing insane it is to do this by ballot initiative.

As Jtsummers pointed out downthread, hg grep searches all revisions by default. No wonder it's so slow. $ time hg grep --rev tip CUDA > /dev/null real 0m0.075s user 0m0.055s sys 0m0.020s Much better. Still m

> this is a highly misleading comparison. Why? When I do hg grep, it doesn't show me blame or anything; the output looks almost identical to the output of git grep. If it's doing work and then throwing it away, why is it fair

Things like search time are *not* a productivity bottleneck. I would recommend, as a general rule, not generalizing from your development experience to everyone's development experiences. I happen to know that git grep is very

It seems I cannot post a performance comparison without people asking about disk caches. :) First of all, if I just cloned the repos, they should be in disk cache. My machine has 64GB of RAM. Second of all, if they're not in disk cac

In the US, the federal government has acted in a big way to prop up home prices when they threatened to fall. It's hard to imagine how we can have it both ways: If the government effectively insures real estate against loss, then inves

The overhead of storing hashed values inside the hashtable is not to be neglected. If my key type has a fast hash function, maybe I don't need to store the hashed value. But if e.g. I have a hashset of char*s, I definitely don't

Tensorflow has a mode that lets it run on CPUs. I'm sure other frameworks are the same. Isn't the whole point of Xeon Phi that it looks basically like an x86 CPU with a ton of cores? If so there is almost nothing to port, just

I don't think it's a spoiler to say that this is a major plot point in "The Three Body Problem" by Liu Cixin.

Hats off to Quanta Magazine for their consistently excellent science reporting. They manage to convey why this is interesting without sensationalizing "zomg new force".

It's not explicitly stated in the article, but it's very important that we can ask for a whole row or column . If we can only ask for rows, then Peggy can cheat by constructing a "solution" that duplicates a number wit

I know this is unimportant, but I have to say, I strongly dislike this green trendline that they have fitted to the graph. It clearly does not fit. The graph flattened out at Jul 2015.

This is misleading. The question is, what is a better strategy? Like, you lose real value after this scenario, but you would have lost more if you'd have kept the money under your mattress. The only relevant question is: compared t

For me it has a countdown timer, makes you wait for five seconds. Of course, uBlockOrigin's "block element" makes short work of this.

This argument applies to all kinds of taxes, right? If you tax labor, I'll just move my factory somewhere that labor isn't taxed. If you tax my income, I'll move myself to a lower-tax place. If you tax my land, I'll j
