Julia and Matlab use the same (Fortran-based) linear algebra codes in the background.

I think it is great to see that a port of the Fortran code in Julia is nearly as fast as the Fortran code itself. So you can take Julia and write concise Matlab-style code (vectorized everywhere) or write imperative code (loops everywhere) and be equally fast.

Note that the graphs in the post are biased. The Fortran version uses a different algorithm for the solver.

Edit: The Matlab code is highly obfuscated. That is not good for the sake of comparison.

How much of that is about the difficulty of the skill and how much of that is the potential for injury? I disagree that learning those skills is harder with age, but healing is undeniably slower for older people, so you tend to become injury averse.

Wearing a helmet in your car would prevent a lot of injuries as well, and nobody does that. This is just a risk/reward trade off and I (as a Dutch cyclist) feel a few additional deaths on the total population is not worth the effort.

And the things are uncomfortable and impractical: what are you going to do with it when you arrive on your destination? Lug it around all day? Bring a bag everywhere?
Is this a viable alternative to Hyde (the python static site generator) ?

I was using this instead of Jekyll for a hardly updated website and I can't get it running on Arch linux (without putting too much effort into it). The whole system looks pretty dated and dead too (I think the upstream URL doesn't even work any more).

I would be really happy to get a "set and forget" solution, so I can update the site 3 times in a year and don't have to worry about the system.

Is Hugo stable enough for something like that ?
Is the Jekyll Docker image the better solution for this ?

Because, I'm guessing, a lot of people using Mercurial (like me) are just using GitHub. Mercurial has had a functional bidirectional git-mercurial bridge extension for over half a decade and I've never ran into issues with it.

The result is that I happily keep using Mercurial locally even when collaborating with people using Git. I don't see the need to have Mercurial specific hosting. (Well, until Bitbucket finally starts working with obsolence markers so I can use Changeset Evolution).
That was my initial association as well. I actually thought there was some sort of sea blockade to not let note 7s into the country. Then I thought that would be a bit too ridiculous and only then did my brain recognize the other meaning of carrier.

1. Losing uncommitted changes by making two mistakes in a row after non-intuitive behaviour by the VCS is not unheard of in Git.

2. Git is strictly worse than both Fossil and Monotone (two SQLite-based DVCSes I have used) w.r.t. losing _committed_ changes: it doesn't do any sync calls by default, and while their documentation confidently says that fsync is just a waste of time, POSIX guarantees are not enough for safety (ext3 guarantees are enough, btrfs are not — writes to two different files are not guaranteed to be ordered by default, and I have lost commits because of a power failure, and I haven't checked what guarantees ext4 provides there).
I'd certainly like to think that's the case, although unfortunately it does not seem to be. If you read the article I posted in my initial comment, for example, it seems like this involves value combined with PR BS.

If you think that's not the case and it truly is a game changer please do share why
Yes, but you can drastically decrease the danger through infrastructure like physically separated lanes and protected intersections.
My experience is that for most applications, programmers really only need to understand 3 types:

1. An instant in time - often represented as an integer number of milliseconds since January 1, 1970.

2. A date in the Gregorian calendar. This could also be an integer offset from a particular day, but it's better to encapsulate it in a class that allows you to add days or months, get the number of days between two dates, etc.

3. A timezone which is necessary to convert between the two types mentioned above.

Java has default classes to represent Types 1 and 3, but is missing a simple class for Type 2. So I designed one myself: http://calendardate.sourceforge.net

Can't tell if you're being sarcastic or not.
Your comments suggest someone who doesn't do a lot of cycling in traffic. Correct me if I'm wrong. You say that young or old cyclists will get 'clobbered' - what do you mean by this? That a car approaching from the rear will see them riding assertively and simply plow in to them? If not that then what? That the cars will pass them closely as they are forced to move further in to the other lane? If that's your assertion then as others have stated, an assertive lane position is exactly what will save you in this situation - as you have the room on the inside to avoid the passing car.
How about a github-like service, like gitlab or gogs?

It might not be perfect, but that's a possibility. And could can definitely work around your requirements with those.

Docker documentation recently moved away from Hugo in favor of Jekyll.

In the blog article above, they mentioned a problem they faced.

I've been using Middleman for static site for a couple of years. I'm thinking about moving to Hugo because I read HN comments Hugo is much faster than other alternatives. But reading the official Docker blog, I'm thinking twice.

Could anyone tell me the reason why Docker blog took too much time to build with Hugo that is supposed to build really fast?
but goto does point to a label. By giving it a meaningful name you can convey more information than with other flow control statements (except for function calls).

I agree that they should cut costs, but I don't agree with your thoughts of how they do so.

One of the notable things about Twitter is that they're a huge marketing machine. They have hundreds of employees that handle sales, marketing, advertising. Hell, they've acquired startups that handle advertising analytics, and have brought them in-house to build their own platform. They now directly sell contracts to TV channels and businesses that allow them to view how their brands interact on Twitter.

I'd argue that this has helped to create bloat. Anyone that has had to use Twitter's API over the years can see that they've gone from being an incredibly open company to building up a walled garden to protect their brand, in a similar way to how Facebook scaled back their efforts to be an application/gaming platform.

If I were Twitter, I'd give teams the opportunity to split from the company, but to continue to use their platform. If they believe in the product they've built within Twitter, they can be happy to compete against the open market. It allows them to drastically cut their workforce in key areas, while re-opening their product to the world. They can continue to be a sales company, but can fully allow others to continue to build great things on their platform, or to help shape how it works in the next decade.

Dates and times, floating point numbers, even strings... there will be always magic in how data is represented/encoded.

Now in the case of dates, there's the epoch, and a precision determined in terms of that epoch, there are compatibility workarounds between 32-bit and 64-bit time... we add have leap days and leap seconds, and of course: the fact that clocks go out of sync, timezones and daylight saving time, as well as a long long list of things.

Some countries move dates for DST every year.

Then, there are days that "do not exist" (September 1752 in UK/US, etc, when they moved from the julian to the gregorian calendar).
It's not actually clear that there is any problem with current theory - it may just be that our understanding and application of it is incorrect. You can have a perfect mathematical model, but if just one of your premises is incorrect, the output can be nonsensical.

I am a physicist (well, I studied as one, before going technology entrepreneur), and have always sat in the "dark matter is bullshit" camp - so my opinion is likely tainted.

I think a far more likely explanation, as this paper could suggest, is that something far more mundane is happening.

For instance, we already understand tidal forces - that bodies can become tidally locked, that there is an inertial frame shear that drags bodies along around a rotating centre of mass, and exchanges energy between an orbiting body and the centre.... So why is it infeasible that galaxies are tidally locked, and the lack of fall-off in radial velocity is down to the gravitational shear from the galactic core being far more intense than we anticipate, causing the behaviour we see. It doesn't require a rewrite of relativity, "just" of galactic evolution.

Either that, or galaxies are sprites, and lazily rendered ones, at that.

Cycling way too fast on a narrow lane like this?

I'm not saying that he's at fault, obviously the fault is 100% on the side of whoever opened the door, but if I was driving 60mph next to a lane of standing traffic, that would be completely irresponsible, because if someone pulled out into my lane the accident would be severe. Driving in cities requires caution, but I notice that cyclists cycle as if they are alone on the road, zooming at 30mph past standing traffic.

I'm not guilt-free, I used to cycle ~2000 miles a year in a large city and a I did my share of stupid irresponsible stuff on a bike, but I think both sides need a bit of education on how to be safe on the road.
Pretty sad that human greed can force such an adaption.

With that out of the way I wonder how good nature is generally in adapting to human caused problems. This strategy seems a bit flawed as it should lead to a sharp decline in the male population and an overpopulation of females. That could in fact lead to even more danger for the elephant population. Before the damage was spread over both genders but it is now focused on just one.

I'd love to see a list of animal mutations that resulted from human intervention. Would be very interesting to read.

What phones are an alternative to the Note? I use my Note 3's stylus dozens of times a day. No other stylus comes close, as it uses Wacom technology as opposed to standard stylus' capacitance sensing. The Wacom technology needs the phone to support it.

Are there any good stylii for writing text (i.e. dragging across the screen) for generic capacitance screens? All stylii that I've seen are good for selecting things (i.e. pushing against the screen) but terrible for writing.
> Your comments suggest someone who doesn't do a lot of cycling in traffic.

If that's what you got out of it then you're entirely wrong. I cycle a few thousand Km / year.

> Correct me if I'm wrong. You say that young or old cyclists will get 'clobbered' - what do you mean by this?

That the only way in which you can keep cyclists - of all ages - safe is by separating the various traffic streams. By forcible mixing them you are simply asking for trouble.

I'm trying hard to imagine Amsterdam cycling traffic without the separation of low speed and high speed traffic into different lanes and with people cycling like suggested above. The carnage would be terrible.

> That a car approaching from the rear will see them riding assertively and simply plow in to them?

Accidents are called accidents for a reason. That car approaching them from behind may not see them at all due to some momentary distraction. You can attempt to make yourself 'large' and 'visible' but you may still be missed and given the relative difference in strength and weight the outcome is predictable. The best way to stay safe as a cyclist is to stay out of the way of faster and heavy traffic.

> That the cars will pass them closely as they are forced to move further in to the other lane?

There may not even be another lane. And a fairly large number of motorists will not see that as a huge obstacle in trying to pass a cyclist that occupies a whole lane.

> If that's your assertion then as others have stated, an assertive lane position is exactly what will save you in this situation - as you have the room on the inside to avoid the passing car.

Well, in that case you didn't need to take up more room than you needed in the first place...

It's kind of weird how all this seems to center around having a 'safe' place to go to in case the assertive driving ('brave' was the word, why is it considered 'brave' if all it is is safe?) policy fails.

Better to recognize your fragility and play it safe from the get go.
If you read some of their postmortem stuff on that whole situation(which is pretty much an engineering meme at this point) they are in no way willing to admit that as a mistake. Tump would have a run for his money on avoiding admittance of mistakes..

I was right; the 5420 is execrable and makes web browsing very painful compared to the Air 2 (my kids have Air 2's). But the display is so much better than the Air 2's in every way you'd care to mention or measure. It's unbeatable for its intended purpose.

Data Compression, PHP, and the Web
It always depresses me (as an astrophysicist) how poor the communication is on dark matter, and this leads people to unfair conclusions. We have known for some time about the limitations of our understanding of gravitational dynamics in extreme environments - the issue is not that "our theories must be right", it's that we have to square General Relativity (which is phenomenally well tested in other regimes) with the results we see. There are broadly 2 different ways of doing this: you can postulate that not all particles interact with electromagnetic radiation (after all, why should they?) or you can come how add extra terms into your gravitational laws.

Both of these have been tried, but there are many reasons why the majority of astrophysicists prefer the dark matter approach. Firstly, there are observations which suggest large regions of mass that are not aligned with the visible mass (e.g. the bullet cluster). Secondly, dark matter can explain the statistical properties of the Cosmic Microwave Background radiation in a way that can not be achieved with ordinary matter alone. Thirdly, when we include dark matter in simulations, we get results that are a very good match for the universe as we observe it. etc. etc. If that weren't enough, we know that there are plenty of types of matter that are dark - e.g. neutrinos, early black holes etc. Whilst none of these have yet satisfied the conditions for dark matter as we understand it, it's perfectly possible that we have already identified some of the constituent parts, and there is a list of potential candidates as long as my arm that the particle physicists are working their way through.

Finally, the biggest annoyance is the intimation that we are all just one big cabal. Let me put it like this: if you could provide indisputable evidence that dark matter was wrong, you would be a superstar in our field and everyone would be phenomenally excited, because it would demand the hunt for new physics. Scientists are a rational bunch, however, so any evidence must be weighed against the existing evidence already observed (which, as above, is substantial).

Dark energy is slightly different. No one know's what this is, but models with a dark energy component do very well at modelling the universe. The question is, why? No one is pretending that this is a solved question, but what we do know is that whatever is driving the universe's accelerated expansion has properties that are very similar to what dark energy is.

tldr: There are loads of great reasons for thinking dark matter exists, contrary to many posters here, and it is well accepted that dark energy is a mathematical term that represents something of unknown physical origin.
