It's already on there for some of the benchmarks at least. It generally is roughly between 30th and 60th place depending on the benchmark (with outliers in both directions). That said, HTTP.jl is not a library that has had a ton of work in Julia, and it's probably not what you want to write a high performance webserver in at the moment. I don't think this is a fundamental limitation, but just a domain that needs a couple thousand dev hours to make competitive with some of the more mature frameworks. Another part of the problem is that Julia has some fairly well known garbage collection performance problems. GC performance hasn't been a major dev priority as of yet, since the language is much better than most high level languages at eliding allocations or stack allocating variables (so it doesn't make as much garbage for many workflows). That said, for GC heavy tasks (string stuff often is), it is a major problem that is starting to get a bunch of effort put into it. Hopefully in a year or 2, these issues will be solved. It's nothing too fundamental, just that the current GC only has 2 generations, and the heuristics for moving objects between generations are not tuned especially well.

False. All you really need is a bijection: McCarthy himself suggested f[x;y]<=>(f x y) and it seems reasonable (and it turns out to be actually useful!) to declare a domain of f where you permit xfy<=>(f x y)

One of his students implemented this: http://i.stanford.edu/pub/cstr/reports/cs/tr/68/92/CS-TR-68-... which certainly has... other issues, but I don't agree infix syntax is incompatible with lisp.

> operator precedence, readable equations, etc.

Yes please.

"readability" is usually given to mean "most people believe they can read it" and not something useful like "most people understand it fully", and nearly any reduction in typing that operator-precedence can offer can be obtained with a simpler rule (like right-of-left) and ordering.

That is to say these things (in their usual meaning) have net-negative value to programs and programmers, are a frequent root-cause of bugs.
In some cases there can be a large improvement going from status quo (if status quo is rather lacklustre) to a simple model, and it may not be worth doing anything more complicated if the accuracy of the component in question is no longer a bottleneck of overall system performance.

Maybe a simple model with a well-chosen prior informed by domain knowledge does the job.

No that does not shock me. But the point is that one strategy can be good for one goal but bad for another. Going around Chinatown and encouraging the populous to do the same "to combat racism" is obviously at odds with "be careful and social distance due to covid". Does that shock the shit out of you? I'll be honest as well, I think Pelosi's real motive there is to do the opposite of what Trump wants, rather than combat any racism, but that's just my personal opinion. Maybe she genuinely wanted to combat racism, I don't know, I'm not inside her head. But it's a terrible strategy to combat covid.

i set up my first real blog over a decade ago. i picked wordpress, because that seems to be the default, and i didn't know any better. oh my god, i hated maintaining that thing so, so much. it pretty much killed my desire to blog, as a matter of fact.

i recently started another blog, and this time i used a static site generator. i wouldn't recommend such a thing for non-technical people, but if you are willing to get your hands a little bit dirty, it is a hell of a lot easier to fix than wordpress ever was.

Agreed - the headline is misleading.

The article states that it would actually be illegal for GitHub to release the data.
That's categorically untrue. Almost all websites are first developed by a developer on his local machine, and then when it's ready to showcase or put online, it will move to the 'real' domain. It is no different for WordPress, and it's true that moving a WordPress site from one domain to another is a bit of a headache.

It should be "gather all things, move it to another place, change the domain name somewhere", but instead it's "gather all things, move it to another place, change all the links, change the domain name in two different places, hope you didn't forget anything or made a mistake somewhere". There are plugins to help you do this though, but all-in-all it's an annoying inconvenience.
It looks like the real issue is "we wrote all the camera code ourself rather than using battle tested libraries".

The android camera API for example will tag every frame with the timestamps and exposure settings it was captured with. Unit and integration tests can simulate dropped frames and verify the algorithm still runs as it should.

I would guess they tried to go for direct camera hardware access and ended up writing their own logic to schedule frames, and it contained a bug.
They wanted a protocol as opaque to middleboxes as possible. SCTP probably isn't, that was not an issue back when it was created.

Is Taiwan Getting Enough Vaccines to Secure Chip Productions?
In the book Sustainable Energy – without the hot air, Sir David MacKay says that the reason the industrial revolution happened in Britain might be due to the amount of coal Britain had. Equal (at that time) to the amount of oil under Saudi Arabia.

Link: https://www.withouthotair.com/c1/page_6.shtml

Relevant paragraph:
"Something did happen, and it was called the Industrial Revolution. I’ve marked on the graph the year 1769, in which James Watt patented his steam engine. While the ﬁrst practical steam engine was invented in 1698, Watt’s more efﬁcient steam engine really got the Industrial Revolu-
tion going. One of the steam engine’s main applications was the pumping of water out of coal mines. Figure 1.5 shows what happened to British coal production from 1769 onwards. The ﬁgure displays coal production in units of billions of tons of CO2 released when the coal was burned. In 1800, coal was used to make iron, to make ships, to heat buildings,
to power locomotives and other machinery, and of course to power the pumps that enabled still more coal to be scraped up from inside the hills of England and Wales. Britain was terribly well endowed with coal: when the Revolution started, the amount of carbon sitting in coal under Britain
was roughly the same as the amount sitting in oil under Saudi Arabia."

Of course this is undoubtedly true. However, deleting the information creates a Streisand effect and a much stronger belief perseverance and backfire effect compared to annotating the information with a counter-argument.

Between the three options of "delete", "annotate", and "leave untouched", I think the least-bad option is probably the middle one. It's not going to dissuade many people and will only reinforce beliefs for many, but there's not much else that can be done.

Oh yes, legacy is the best place to learn. You replace something that's 'working' with something that keeps working but better. You write tests against a working system. The thing is already giving value, so you don't have to worry about that. And usually the problems are more and more complex as the code 'matures' so challenge. I don't like working on big greenfield projects. Give me a somehow working big ball of mud codebase to steer and I'm a happy man.
AMD Chips Supply to Rebound as TSMC 7nm Node Capacity Eases?
A few things:

The world would be vastly better without patents in my opinion. Faster innovation, cheaper goods, less environmental waste. Medical technology would be better and cheaper. High technology like MRI machines would become cheaper, health care would become cheaper, etc. Really massive benefits.

It could be that there are certain fields where patents actually help to some degree. In other words an artificial monopoly is the only way to secure enough funds to cross some threshold for viability. Well, fine. We shouldn’t throw out all of the benefits of open innovation just because a few areas will need help. We can recognize what those areas are and provide government funding for investment, like in health care. Then we still get all the benefits of open innovation and we can distort the market with cash injections instead of planet wide distortions on copying.
What baffles me is that huge portion of those small business websites have absolutely no need for Wordpress or any backend altogether. At best they need some static site generator and a CI/CD pipeline maintained by the provider to rebuild the site if it is an actual blog, which is not that common.

Not entirely sure, since the shipping part was not organized by me. I did give relatives about 1000$ to cover any necessary expenses, which would have been 1/10~ the cost of stuff being shipped. In the end that worked out well, but it took about 7 months from packing to shipping for everything to arrive at their front door. Half of the time waiting was spend, wrapped in a warehouse prior to it being packed into a container.

Ask HN: How do you determine what your customers/market want?
I've been working on this model deployment/hosting platform for a while now and we've gotten a hundred sign ups already which is at least some validation for the idea. The vision that I had in mind was like a Vercel or Netlify where you push a framework of some model and it's dependencies, then it gets deployed and ready to use via an API.

The problem is that most of these users sign up and never come back or interact with the platform at all. There are also a few of these sign ups who have used the platform once and come back every so often. This indicates to me that there is something that we're missing, some need that we're not fulfilling, for these users that's making them leave.

It's been pretty difficult to get constructive feedback on the platform since they're generally quite unresponsive to our emails.

Being a tech-founder, marketing and sales really isn't my strong suit, so I'm really interested in hearing how some of you have overcome this and any recommendations or feedback that you guys have for me.

My questions are:

- Are there some best practices I can follow to market a product like this? If so, what are they?

- What are some good ways of getting customer feedback and how do you determine if what you have is what customers want?

- What are some better ways to get feedback than just cold-messaging random people on different channels (e.g. slack, discord)?

- (Very subjective) What are your thoughts on another deployment platform? Is it something worth getting into?
> How many people know what the meaning of fop is these days?

I don't know. I do, and I'm not a native speaker. And people using Greek dictionaries probably skew towards being pretty well read.

But that's besides the point, since I suggested using some other word if they found "fop" offensive.
The article links to NASA but here it is anyways. Let me skim it and I might add some additional information here but go and check out the first picture there yourself - it is amazing. It could as well be an aerial photograph of a desert area on Earth by the looks of it.

https://mars.nasa.gov/technology/helicopter/status/305/survi...

OK, so from the NASA article, it seems that they use an inertial measurement unit [0] (think an accelerometer/rotational sensor similiar to what your smartphone uses) that reads out heading and acceleration 500 times per second and sums it up to get the the helicopter's position. This is "dead reckoning" [1]) which unfortunately suffers from accumulating errors. To work around these accumulating errors, they sync their prediction to camera data thirty times per second by predicting how features visible on the surface should have moved in this time. So, sensor fusion [2], in a sense. The images are delivered with timestamps (I would have been surprised if they were not, to be honest) but one of the images went missing and for some reason, its timestamp was not. (Variable not cleared? Are they maybe using parallel queues to match images to timestamps (would be very weird, imo but I am no helicopter scientist?)). Either way, the following timestamps were now attributed to wrong images. I really wonder how that happened and hope they expand on that later. As the system predicts how far a feature in an image should have moved between frames, things were now considerably off (example: from the IMU prediction, a feature should have moved 1 unit per second but with a missing frame and the previous timestamp, it now looks as if it moved 2 units in a second) and the state gets updated with this wrong information.

Here is an interesting bit about safety margins from this article by the way:

Despite encountering this anomaly, Ingenuity was able to maintain flight and land safely [...]. One reason it was able to do so is the considerable effort that has gone into ensuring that the helicopter’s flight control system has ample “stability margin”: We designed Ingenuity to tolerate significant errors without becoming unstable, including errors in timing. This built-in margin was not fully needed in Ingenuity’s previous flights, because the vehicle’s behavior was in-family with our expectations, but this margin came to the rescue in Flight Six.

Most people have good health care plans through their employer that pays for most of this stuff.

A mistake more expensive than ‘null’
That's fair. That said, the fact that writing a BLAS implementation in a high level language seems like a favorable benchmark does kind of show my point that for numerical computing, Julia is really fast (especially for a high level language).

As a general purpose language, I'd probably categorize Julia as fast, but not crazy fast. Numerical computing is definitely where most of the man hours have gone into development. As a general purpose language, Julia probably ends up at around the same place as C# (not as fast as C++, but still pretty respectable). That said, this is an area where the main thing Julia needs here is more optimization on some of the libraries that already exist, and some new libraries to extend the language's reach further. I don't think there's anything fundamental holding it back from getting closer to C++ performance in general computing. It uses the same compiler (LLVM), and it's pretty clear that you can get Julia to output the same assembly code. It's just a matter of having enough devs pushing ecosystem forward.
As of 2020, most SV interviews for Devops/SRE were not Leetcode - just normal programming, though possibly kinda lengthy.

Long enough that they don't co-ordinate, essentially, which would show in how they acted.
