Not much point in keeping the "3." around when we don't expect a "4.0" version to happen in the foreseeable future.

I love that they are making the compose key feature more discoverable. It's the best way to type strange characters like å, ř or ©.

Those couple of years where the carbon is in the form of methane instead of CO2 have a big impact because methane is a much stronger greenhouse gas.

Is that 69.3 million asking price a reference to something or is it just a humorously large number with no special meaning?

More importantly, it's directly referencing the contents of Dijkstra's essay and arguing that "go" is bad for the same reasons that "goto" is. In most of the other considered harmful blog posts the title is jus

One of my favorite things about Shellcheck is that the error messages come with a link to a wiki page about the problem. Does anyone know other programs that have a similar approach to error messages? https://github.com/koal

If we're doing that then we may as well avoid the exponentiation with `lookup_table[n % 15]`.

I think the parent poster would classify that kind of web app under as a "short running thing". Sure, the application process might live for a long time but the requests are short-lived and independent of each other.

You can assume that all regexes are "anchored". They match the entire word, not just a substring.

It has to be fake words. It's possible to see this because some of the words have to contain things like "cdd", "rrp" and "rxo", which aren't part of any real words.

Is it supposed to have an unique solution or are multiple solutions possible?

The biggest takeaway for me is that I learned about the existence of some utilities that I had never known were there. Specially "factor" and "tsort".

The main thing that changed was not the project length, but that the projects are now supposed to be part-time (4 hours per day) instead of full time (8 hours per day). I'm curious to see how it's going to work out. Halving the st

Extracting DNA from fossils is actually a thing now, in certain extraordinarily rare circumstances. However, that's not the case here. The genetic studies that the news piece mentioned were carried out in present-day hagfish and presen

I also had a similar first impression from reading the name of the project. I thought it was going to be related to standardizing Ruby implementations / the Ruby language itself.

Can you bounds check dynamically sized arrays? For example, a function that receives the size as a separate argument? double f(double *xs, int n){ return xs[g()]; }

by ufo 6y ago
We wouldn't need to go all the way to dependent types, which would guarantee at compile-time that array accesses are safe. Even if all the bounds checking happened at run-time it would still be tremendously helpful.

I wish they would have put that on comments instead of on the commit messages. It's not the first time that I've seen this particular list of banned functions being shared online and every time it happens someone has to explain th

That's the reason why the paper is focusing on damages per dollar of mined bitcoin, instead of damages per mined bitcoin.

Yes, reducing energy waste is an important way to tackle the environmental externalities of energy production. For example, in cold countries one of the major efforts for helping with climate change is to encourage buildings to use better i

The definition they are using is the dollar value of the mined bitcoins. For each $1 of bitcoin that is mined in the USA, the mining process causes $0.49 in health and environmental damages.

In my experience the key challenge is the steep learning curve. You need to understand advanced type theory to really understand what the error messages mean. Another problem is that sometimes there are "obvious" things that you&#

How many people will notice that there is important info hiding under replies? Twitter's UI excels at hiding that information, and at presenting it in a weird order.

In case anyone missed it, this sscanf behavior was the cause of the long loading times in GTA V, a story that hit the front page yesterday: https://news.ycombinator.com/item?id=26296339

The surprising part is that sscanf calls strlen behind the scenes.
839.
by ufo 6y ago
The bug is more devious than that. The code looks linear at a glance and the culprit is that sscanf is actually O(N) on the length of the string. How many people would expect that?

Oh dear... that's one of the biggest footguns I've ever seen in all my years of working with C.
