If you want A^-1 b, where A^-1 is a known n×n matrix and b an n-dimensional column vector, you can just use the naive method, which takes O(n^2) steps. If you use the new linear solver, you'll need O(n^2.332) steps just for that, and additionally you'll have to find A somehow. So matrix-vector multiplication is faster.

In the article, they're comparing it to multiplication of square matrices, which is slower, but only slower than solving a single system of equations. If you wanted to multiply square matrices with the new linear solver, you'd have to solve n different systems of equations with shared coefficients, which would end up slower than the naive O(n^3) method, unless you can share work across instances somehow.
Free and open source software is not all about "best utility for users". It's about freedoms being valued extremely highly; people self-select for being or not being the consumers of it.
People lie, especially in matters of attraction - eg it is still not safe (legally or culturally ) to be a homosexual in much of the world (including swaths of the US). Thus the EEG-based “mind reading” approach. There’s still much work to be done, clearly , but “simply asking people” is anything but straightforward.

Or at least require a comment explaining it, before someone needs to dig through the code.

Powers of three, five, and seven sounds a little bit like Totvald's very own little FizzBuzz game hidden in ext4's file-system source code.
The mac is extremely good in being bad in this. CMD+Control+Q locks the computer. Incredibly useful for office places, where you are not alone. Not quite hitting that Control-key though, and your app quits.
Mine you get a little "zapper" to scan the bar codes with. I select, scan, and bag into my cart. When I get to checkout everything is bagged, so I save that time as well.

The only "pain" is having to look up the produce and weigh it, but with a little practice I got to be pretty fast at that too.
> A service has constant administration costs which are paid by the service provider. A properly designed library instead moves these costs to the users of the library.

What really happens is that users pay money to some service provider that has said administration costs and margins for providing said library as a service. Users don't want costs related to maintaining a library or infrastructure that it needs to provide its service to them. That's why things like AWS and Azure exist.

Unless of course SaaS providers are your "users" in this case ...
There are plenty of books that are no longer being published, but you are not prevented from buying them on eBay. The issue is more than active publication, it's access.
I used to be a lifeguard. My pools weren't nearly as busy as that website's examples. If they were, I probably wouldn't have done the job, as that looks super stressful. Much to my surprise, however, I did spot the drowning child at around the same time as the lifeguard. Youth employment validated.
There's an interchangeable, overpriced, soulless gas-station chain on nearly every street corner in my town. When I fill up my tank at any one of them, I'm forced to listen to the sound of 9+ pumps puke out celebrity-gossip, advertainment pieces, and PSAs telling me about the coronavirus. You can't mute them anymore. Inside, the shelves are lined with nearly identical selections of overpriced merchandise.

I could be anywhere in the midwest.

I still have have a preference for the station I use, because the staff and I at a couple of the stations recognize each other, and have developed rapports over the course of many 30s smalltalk sessions. It's superficial, but it helps build social trust. We exchange small favors. I forgot my wallet one day, and the guy behind the registered covered for me and told me to pay him back when I could. I've told off a belligerent customer or two in ways they couldn't without being fired. We've discussed the local jobs market, and at points turned each other on to different employment opportunities.

I'd pay higher prices if I knew it got them more money (and got rid of those damn telescreens).

Nevertheless, I wouldn't pay for that kind of interaction directly if I could. I have a couple groups of regular friends. If I wanted social interaction alone, I'd get with them.

It's not really about the interaction itself, it's about having some semblence of place and community in a world that's too big, too standardize, too indifferent, and too increasingly automated to think about you as anything other than an instrumentalizeable commodity, or a function to be optimized.

Every technological step forward like this puts us under increasing surveillance, dedifferentiates the spaces in-which we live, and obviates the labor of large segments of our society while reducing the power of all but a select few.

Hyperbolically, I feel like we're all just a few years from being stuffed in padded rooms with an ad-supported games console and permanently affixed morphine drips to optimize mortality, health, and quality of life metrics.
The author does not try to explain the subtleties of the design decision. Yes, putting two opposing choices next to each other might encourage some errors, at least initially, but what if the designers decided to do this because users were already trained to see this pattern in all other software? Because they were building on top of an already established mental model?

Red is a double-edged sword: it has been identified as attention in nature (danger and attraction), so psychologically speaking it might warn AND nonintentional lead a user to a perceived action.

What is the solution? Would you put it opposite to each other prompting the user to become frustrated when they cannot find the button to hang up? (X) closing the app does not imply hanging up. This is not a life or death situation (unlike healthcare), so at least offer some explanation of why it was designed that way or offer an alternative solution.
Isn't it also precluding several non proprietary compilers as well though? In turn making LLVM more popular and making it even more appealing to propriety compiler authors.
What you call "Coreutils" should be called GNU/Coreutils.
Exactly, if grep behaves differently in your scripts and your shell, there's no point in not using ripgrep (or ag, or silver searcher, or whatever strikes your fancy).

>The limits of regulation. There is no way to plug all loopholes.

Sure there is. Just ban export of wood and wooden items.
> Road safety is a major, global public health crisis. More than 1.3 million people die on the world’s roads every year, according to WHO. That’s more people than die from HIV/AIDS, and is equivalent to a passenger plane’s worth of people crashing every single hour—or one death every 30 seconds.

> I’ve spent over 20 years working in crash avoidance research, in the belief that improved driving technology is the key to reducing these needless deaths.

This is a noble goal, but I find it really damn hard to ignore the possibility that this is all just another ploy by Google to steal our data and violate our privacy. Just imagine trying to push back against a technology that saves lives for something as "frivolous" as privacy.

Why does it seem like the consumer can never win? The free market is supposed to be self balancing, yet I can't remember a time where it actually felt that way in the technology sector.
It is a reality. Another point is that piece of code does not mean everything. When it run on an optimised platform, it will give much value. For example, a multi-core algorithm. When it is a service, that can be ensured. Also, the Library and the beneficiary application run on same memory space (normally). So the lib code can cause crashes or can hack privacy. Another thing is your secret-sauce is public now. So it can be copied or reverse engineered.
>Classic pyramid scheme. It works great in poor countries since people aren't as educated

Bingo! Schemes like these were popular in Eastern Europe after the fall of the iron curtain where some people got rich and a lot were left holding the bags since most had no financial education but were poor and desperate enough to fall for get rich quick schemes as there were no laws against this sort of stuff during the transition phase to capitalism.
Oh... there was this guy last time on HN who insisted that signal is open source but they want to"protect signal brand" and that means not allowing federation or even third party apps or servers to connect to official servers because.
Then goes on to say for a lead "has explained why it disant federate with element" and that should be it.

According to them, its "open source" but see, dont touch. Also, because its built over a "foundation" it has less chance of being taken over so count your blessings and join signal because.

Yuck.
I have done plenty of jobs that are shit pay in the same tier of manual labour (stockist, hospitality) and have never met anyone in that field who didn't want to do somethinge else if possible.
I self-published a 300 page book through Ingram in 2012. It is pretty niche and only sells about 200 physical and 50 or so Kindle copies a year. The whole thing was done in LaTex with a Tufte book package; there are a few tables and images but the vast majority is text.

Have had many unsolicited comments from those who have handled/thumbed through it about the high quality of the book (look/layout/feel) - most are surprised that it was not done by a 'big' publishing house. Frankly, my own opinion is that the quality is at least equal, probalby higher, than what is being churned out today by big names today. Part of that is the format/layout as a result of using LaTex, the rest is the physical material characteristics from using an excellent printer. None of that speaks to the actual content, of course :)

I did eventually make a kindle version, unfortunately I do not recall the tool chain used.

Highly recommend Lightning Source (Ingram) for your printing/distribution needs if you are serious about your publication.
My understanding is shrinkage typically refers to the sum total of all product received but unsellable, whether from theft, spoilage, or or breakage.
Old growth wood is physically different from what you'll find at a regular lumberyard, so I would like to think no, but I'm sure it will be turned into marketing speak eventually.
I really dislike the way the data is being summarized as "100% avoided or mitigated*".

First, they're omitting the types of case they're failing to mitigate (rear endings in this case). Cue "60% of the time it works every time" anchorman scene.

Second, "mitigated" is defined to mean a 25% relative reduction in chance of serious injury. Which is good, but again smacks of "60% of the time it works every time".

Basically, it looks to me like someone wanted to be able to show a bold blue 100% and required the definitions they were using to be massaged to match. And apparently they got their way. This has damaged my trust in future summaries put out by Waymo.

A more truthful summarization style would be e.g. "X fewer serious injuries over 72 incidents", referring to expected injuries and simulated incidents of course.

The banks also don't seem to be all that interested in interacting with their invidual customers in the flesh.

"Why is do I get an second call when I’m busy?"
Can't it already figure that out based on the query? E.g. I'm asking for the value at key `7`. So my query asks for the encrypted value for whatever `7` gets encrypted to. The db/algo already knows I'm asking for `qasfdj`, and that its returning `zsqwer`.

It doesn't matter whether it walks the dataset or not, it gets to know those two values. So may as well build an index on the keys?
Resident in Sweden here and heavy user of the self-checkout.
My experience is that self-checkout is slightly slower than the serviced one.
For a serviced checkout I try to put all bar-codes towards the cashiers scanner (it is a nice thing to do, the cashiers do not like juggling either) when putting stuff on the belt and I will need to unpack from my basket, pay and pack it to my bag.
The same is operations needs to be done for the self-checkout but even the best setups needs some managing of the machine that the cashier would have parallelized in a serviced one. Usually it is slightly more fiddly to do packaging and scanning on a self-checkout system than on a serviced larger belt.

However, considering that there are usually many more self-checkout terminals available with much less queue it means that the total time spent is less than on a service one.
My local store, open until 23, usually closes down the self-checkout terminals the last hour since there are too few people to make it worthwhile and you rarely have a queue to the serviced station.

So I totally agree that the serf service checkout is slower for that actual station but considering that the store can cram in much more of those in the same space and they need much less personnel to manage it saves everyone time and money to use them, unless there is no queue to the serviced checkout (and personnel is manning it at the moment).

One example of this is computer games. There are games like StarCraft 2, Diablo 3, where server is required even for solo-playing and it's not possible to play offline. I think that one of the reasons is to make it harder to crack a game (as you would need to re-implement server) and to make a cracked game objectively worse (as your implementation will not be as polished).
How did you get "people are polite" from an article titled, "people literally don't know when to shut up"?
1990s advice on a 1990s website. It's the opposite. We need to move away from package hell by splitting our work in two opposite directions: on the one hand, we should move back to large, effective standard libraries; on the other hand, we should move toward more services, fewer library packages. A project shouldn't need more than a few packages, usually for something like a database connection protocol. Working with libraries is the worst part of the job.
That's ridiculous. All humans make mistakes.
Fragmentation also is a big issue. Not only in the sense that there are separate very different sign languages (American Sign Language has little in common with British Sign Language, they are not mutually comprehensible), but even for each separate sign language you also get different 'dialects' in different areas/major cities, which are mutually comprehensible but have lexical variation depending on the speaker's location/community that needs to be properly represented in your datasets in order to be acknowledged and understood. In some sense it seems the equivalent of what the fragmentation was for spoken languages before the printing press and age of nationalism facilitated language standardization.
Wouldn't it just be finding the line of best fit in the embedding space, mapping the embedding of each face to the amount of activity?
I'm on stock Android using the stock Google made Clock app for my alarms and I still sometimes need to double-take and make sure I'm not snoozing instead of turning my alarm off.

This[1] is what it looks like when the alarm goes off. (Swipe left to the "zzz" snooze icon or swipe right to the off icon). I can't always rely on muscle memory because I am not always consistent in which direction I put my phone down on the nightstand. This is not the best UI for a person who has just been woken out of sleep and still groggy.

Alternative viewpoint:

They'd really rather you not get in their way, anyway. It isn't awkward for them until you try to help. They enjoy the feeling of power/superiority they have over you. That's why they smile while you stand there naval gazing.
Is it even legal to require standards compliance in the law?
I thought that law has to be open and available to everyone?
Thanks for the kind words. I don't know much about openVMS. I read your profile bio. I'm not sure I quite grok all the details, but I would like to caution you: ripgrep is still, roughly speaking, a "grep." That is, it exhaustively searches through corpora. While it has some "smart filtering," it's not going to do much better than other tools when you're searching corpora that don't fit into memory.

I do have plans to add an indexing mode to ripgrep[1], but it will probably be years before that lands. (I have a newborn at home, and my free-time coding has almost completely stopped.)

Can you explain how you view every trading or market isn't a "Pyramid Scheme"? I don't disagree, but if you buy Apple stock at price X, you hope that someone else buys it at price x + y.

So in a sense, every investment you do is with the hope that someone else is buying it for a higher price in the future.
No, no it wouldn't. A 600 dollar GPU these days is a 3060ti which is rather unfortunate.

The Xbox Series X and PS5 are phenomenal pieces of hardware that are pushing the limits of consumer goods. Both support 4k 120hz and HDMI 2.1, free sync and much more.

Instant on, fast resume, keyboard/mouse, controllers, they're a hell of a bargain.

The Xbox One is older than the 1070 and cost much less and still is supported to this day.

Richard Hamming talks of the development of FORTRAN and Algol in his History of Computers talk. He recalls FORTRAN being received as something between an abomination and a stupid trick.

Algol, in contrast, was backed by many international groups and is described as "an attempt by the theoreticians to greatly improve FORTRAN" (by way of all their great, formalized knowledge and 'wisdom').

The seasoned experts always think they have some secret that the upstarts are missing, a special sauce that no "true solution" built by "true engineers" would be without. And then their overengineered designed by committee and compromise solutions stumble out of the garage and collapse in a heap. Meanwhile, those things built by people more motivated by a desire and a passion than by signaling their expertise soar past and into fields and uses their designers never imagined.
