I read the paper completely differently than you. I think you were influenced by the title of the news article. The paper seems to me very reasonable:

Given the goal of implementing an architecture for part of the tasks of the OS for a 32,000+ core supercomputer, can we use mathematics to model such an architecture? The answer is yes, the mathematical model is defined and the simulation of that compared with the equivalent implementation provided in the current Linux.

The way I see it, it was then never about "replacing the whole Linux" but about "how to better implement some piece an OS which is to manage e.g. 32,000+ cores and simultaneous forkings on them."
> You did read the part about outsourcing companies faking all of these credentials, right ?

Yeah, I agree that's a challenge. But I am sure there could be some metric buckets like compensation bucket based on the location, employers market cap bucket( granted this could again be unfair to certain companies).

> But even if not faked, how would you compare people from wildly different institutions and countries ?

US Educational Institutes and immigration agencies of other countries have already solved this problem. There are institutions like WES which do a GPA and educational credentials evaluation.
If you limit the IP to the residential IP space then VPN costs become huge. You need some resident to rent his IP to you. If those residents get punished by their providers for that behaviour then soon you will have to rent apartments to buy your own connections. That's hundreds of dollars.

Now, if Amazon would be sincere about preventing fraud, they would ban the IPs of fraudulent comments and somehow cooperate with the providers if they use random IPs. In other words, you would have to rent a new apartment for every bad review. That's an exhibitive cost.

Various super computer labs are using single board computer clusters of similar node size (but obvious less compute) in order to simulate the parallel compute issues without consuming the main cluster. It is just another step in the testing process for complex software that might very well waste cluster resources.

I read Dragon's Egg recently, and one of the key leap from barbarian to civilization that the neutron star aliens make is (simplistically) to count past "many" and think of quantities / numbers abstractly.

Our ability to track distinct objects is impressive by our own standard, and we're pretty good at understanding "big" numbers, say somewhere between a million and a billion. But in the scale of things, we're much closer to the hunter knowing his kill will feed his tribe for many moons versus being a starfaring race.

It's always a capacitor![1]

These mature cheap reliable mass-produced electrolytic capacitors of which we rarely see fault today, sure had quite the rebellious stage[2] [3].

Interesting, from the announcement on badcaps.net[3]:

"Back in April 2002, I had an idea to start a business (actually spinoff of another business) servicing motherboards at component level amid the mass capacitor failures plaguing the PC industry."..."The store boomed from its launch all the way up until about a year ago. Over the last 6 months or so, I have sold very few capacitors. Once my stock depletes, I will be shutting down the Badcaps.net store."

Perhaps the downvoters are unaware of the specific Chinese program of the social credit system experiment ongoing even right now? https://www.wired.co.uk/article/china-social-credit

If so, it is understandable that they would not see this as any serious matter, because in the west, the maximum that such a system is worth of is a Black Mirror episode. In China, this is now an everyday reality for many people.

"We're no longer in the days of a master cylinder responding to pressure from a driver's foot by simply sending hydraulic fluid to drum brakes."

I think there are many cars on the road that literally fit that description, and certainly it's still legal to drive such. More cars that you'd think have rear drum brakes.

The complexity of electronic aids is not really germane to the complexity of maintaining brake systems when you normally don't get failures and if you do there's going to be a code that tells you.

I don't know exact numbers, since I don't do any user tracking. But I know of numerous users who are already experienced with Clojure who have switched, myself included. Cursive currently has paredit on by default, but I'm going to switch that to parinfer.

FWIW Emacs users do ask about parinfer in #parinfer on Clojurians because they actually want to use it. There currently isn't a smart mode for Emacs though, and that's what I consider the game changer. I suspect that uptake will be good once that's available.

Agreed. The article implied the "special" transistor was used to create something like white noise. It'd be interesting to know what that noise sounded like compared to "normal" white noise.

I did staycations for 10 years and now I am doing 10 years of going as far as I can; I vastly prefer the latter. At home we inevitably end up doing things that do not, for my definition anyway, belong in a vacation. And the stress thing of vacation goes away if you just do not plan anything upfront besides getting the tickets. We sometimes end up just walking through nature or city instead visiting 100 places hurriedly with some guide. And that is fine; for me vacation means that I do what I like; I do not need to see anything for that sometimes.
Erm, why not just configure auditd to detect it instead? Though not sure how widely available that facility is outside of Red Hat.

> so making things hard to repair would likely be costing them money.

It's easier for them to repair because they have access to the manuals and diagnostic software necessary to quickly identify the issue.

> Electric cars are so much easier to repair in my opinion because of their simplicity

Parts of them, but the highest cost repairs on Tesla's are by far the body work; which is somehow an order of magnitude more expensive than other cars.

> Replacing the drive unit in most electric cars is like 2 sets of wires and 4-8 bolts.

That's a gross oversimplification and completely ignores the necessary reprogramming to make the replacement actually function in the new vehicle, which is precisely the problem with their repair model; you _can't_ actually do this yourself due to software barriers.

> But that'll change as electric vehicles become more common.

And as soon as the manufacturers release the necessary information to make them functional on their platform.

I think part of the problem with rationals is that they have much more chaotic memory usage, even more so than normal big integers. This is because while integers are straight forward to estimate memory usage based off of size which is easy to reason about, rationals grow rapidly from both multiplications as well as divisions. Furthermore, they get even more complicated since they can shrink unexpectedly from either operation if you are continuously optimizing using GCD.

That was a great read, thanks to the author for making sense of entangled history between decentralization and file sharing.

I don't see why they seem to conclude that decentralization can only exist to circumvent the law, though : it's not because it happened like that in the past that it can only happen like that in the future.

The author is noticing that privacy is a big concern nowadays, but is somehow discarding quickly that remark. I see it as fundamental. Nowadays, privacy is not just a theme for activists or weirdos whom most people think "they're going too far". Nowadays, my aunt and my grand mother speak out privacy concerns about facebook (ironically, on facebook). There is also in the general public mind this vague idea that we're allowing a few companies to be stronger than governments (and thus, than democracies) and that they now own internet.

All of this is very fertile ground for decentralization, we'll see if that ground expands or shrinks, but this is clearly not about working around the law.
It just occurred to me that there may be another thing I don't see yet mentioned in this thread that gets in the way of repairing Teslas - from what I've read, they make constant changes in their cars during model years, so how do you know which exact parts you have in your car? I bet it's underdocumented.

I have been trying to fix various things in an old car from the 80s, and one of the more annoying aspects is trying to get a replacement part and finding there is a rare variant that I need but has the same part number as the common one. There are also a lot of parts that don't have diagrams or part numbers at all, because they weren't anticipated to be serviced normally.

Can someone explain to me the fascination for git, despite the constant stream of "how to fix [insert various git issues]" articles showing it's very difficult to use, at least compared to the alternatives? Most people's work streams only need something as simple as hg, which would also save them a lot of time and hassle.

My personal impression is that it's a fashion thing (people think it's cool to waste a lot of time on git, because git is cool and fixing git problems feels like real work, because you're using your keyboard and all that), but maybe someone has a different perspective.
It's impressive to me that they can make running changes (like reducing the number of spot welds in the Model 3) without having to retest/recertify.

I expect senior backend/fullstack devs to be experts at at least one language, at least one RDBMS, and at least one extra tech like elasticsearch, mongo, redis, etc.

OP, ignore stuff like this. "Expert" at a language is an extremely high bar, and not very important. Workplaces that focus on language expertise (and other narrow skills like "mongo") tend to not be great places to work. By definition the leadership at such places clearly doesn't understand what's actually important. These are the places where management obsesses over ludicrous metrics and where the worst whiteboard interviews (with questions about obscure language features) are conducted.

There are places where you're seen as a person rather than a bucket of buzzwords. Such jobs value your general intelligence and emotional intelligence a lot more than # years in language X. There's room for you to bring all kinds of skills and expertise to the table and you don't have to worry about fitting some mold.

The real measure of success at such places is getting stuff done, and that's done at the team level. A team doesn't have to be N "experts" at language X and trendy technology "Y".
> Almost nobody sees or reads corrections.

Unless they're "big enough".

> At least on social media if the correction is big enough it'll be brought to people's attention.

And if it's not, it wasn't big enough, or if it was big, but people didn't like it enough because it doesn't suit them, then it still doesn't get spread. Doesn't make it less of a correction though, does it? If you apply something super vague as "big enough" to one, apply it to the other as well.

> Have you really never seen a correction posted on reddit?

Same here: have you really never seen a correction in a newspaper? Or letters by readers taking issue with previous articles, for that matter?

> Every other day there's some news article that has as the first comment a correction of the article, because the article is wrong or leaving something out.

That says nothing without looking at the volume of falsehoods that are uncontested, or at the instances where the article is correct, and then the comments contain falsehoods about the subject.

The CTO at my first job out of college was the chief architect for JavaSpaces. I think we'd used it in an early version of the product but had migrated away from it by the time I joined full-time.

Aside from the fairness issues that other commenters mention, tuple-spaces work at an awkward level of abstraction. You can easily implement many other distributed concurrency models with them - semaphores, message queues, producer/consumer channels, broadcasts, even MVCC and transactions - but oftentimes, in the application it's more natural to just use the more specific abstractions. For example, you could implement a message queue by putting tuples of [type tag, sequence number, ...data] in and taking out the next message of a given type - but usually you'd want guarantees that there are no name collisions among type tags, and that sequence numbers are never skipped, and a mechanism to resend missing messages if for whatever reason they aren't produced correctly. At that point you'd rather just use golang-style channels or a real message queue library rather than roll that on top of the tuple-space.

There are relatively few problem domains I can think of that map directly to a tuple-space, without building some other concurrency abstraction on top of it. Dependency graphs and workflows, perhaps, but there are other libraries to handle that specific problem which also handle things like tracing, debugging, and error correction.

Ask HN: Suggestions for low cost homebrew “HPC” beast?
Over the past few years I've been playing around with the idea of building large number crunching applications for fun and personal research. While the applications I had in mind aren't trivially parallel, they should map well to a parallel architecture.

There are generally two options for running a big parallel application:
1. going to a commercial provider, which is prohibitively expensive;
2. affiliation to a research lab, which is not the case for me and usually requires a research project for you to get compute time, no playing around with toy application.

I was wondering if anyone has experience with building a small homebrew number crunching machine on a budget. The best idea that I have so far is getting a few used server machines with decent GPUs.
The TDD book only applies if you ascribe to the TDD philosophy, which not everyone does. The others are fairly universal though.

(Tagging dang -- am I crazy here for the following observation? Please advise.)

What is it with all the random European-Caucasian men coming in and commenting on how they're randomly selected all the time?

When someone feels like they're being selected-against for bias and when popular and well-researched evidence of such exists, you're minimizing and trivializing their suffering by making the same observation of yourself when you're the majority party. It's a form of passive and latent bigotry you might not even realize you're expressing. I'm commenting publicly and separately from HNthrow22 because plenty of you seem hideously blind to this.

Your case may be true; I'm not disputing that, but the consensus research position is that "people of color are more often mistreated" and this anecdote by the OP fits that position. Your anecdote fits the less frequent occurrences ("more often against minorities v. less often against the majority"), and so by mentioning it, you diminish and belittle the minority person who's being mistreated by suggesting your experience is of equal likelihood; it's not, and you're not being considerate of that fact.

As for me, I ambiguously appear to be of Middle Eastern or Cuban descent--Persian, for the record--and noticed that I'm consistently selected-against for screening about 50% of the time whenever I have either a beard or an extremely well-maintained fade. Of the many, many times I've been down to scruff or a clean-shaven face, it has happened only once, with that singular exception being this past Tuesday night in Tom Bradley International in LAX.

In closing: there's nothing preventing you from voicing your less-likely experience, but by doing so, you're diminishing the more-likely experience faced by minority parties because there's inherently no differentiating context in individual anecdotes.
