8-Year-Old Refugee Wins New York State Championship
|
He only won his age group (K-3), for kids at his age. And there were kids with a rating of 1400-1700 already. Everybody knows that young immigrants play much stronger chess than US kids. So not really newsworthy at all. It would have been if he would have won the real New York State Championship, such as the young Japanese boy Harimoto who beat all the world champions right and left aged when he was still 15. (table tennis). Also an immigrant (from China). In a much harsher and openly racist society.

This has to be flagged for the quality of the news source.There are multiple typos in the article itself (the last word is "recieveing"). The homepage headline as of writing this comment is grammatically challenged: "The ‘Black Mirror’ tech billionaires are investing in to try and live forever"This article provides no sources, no footnotes, no authoritative evidence other than "purportedly..." It editorializes throughout and reads like it was written by a Romanian SEO bot.Do we have any standards on HN anymore, or do we just post and promote articles with clickbait headlines that make us feel good?Also, the post is from 2017. Come on, people.

Ask HN: Dear open source devs how do you sustain yourself

I spent the first 10 years of my career working on and consulting with the open source CMS Plone. Consulting paid the bills. There were occasional paid projects for specific improvements to the core software, though mostly that was done in my own time. Contributing helped build up my skills and reputation which helped landing consulting contracts.It was pretty awesome. For most of the time I was able to live somewhere fairly affordable and earn a comfortable income (though a long way from SV money.) I still miss that community and meeting up with them at sprints and conferences around the world.

Declining worker power vs. rising monopoly power: explaining recent macro trends
|
Although the economy is a complex system and it's dangerous to try to over-simplify, my personal opinion is that there are two main and intertwined causes:1) the cost to participate in the US court system.2) the abuse of copyright, patent, trademark, and contract[1] law to divorce workers from their experience and treat employee knowledge as company property.The time and money involved in both pursuing and defending court cases favors larger entities with armies of lawyers and large war chests. Intellectual "property" cases take especially vast amounts of resources because of the fuzziness involved. Meanwhile, treating workers as fungible producers of ideas that can be bought and sold both reduces the bargaining power of individual workers while empowering companies that can amass large portfolios of patents, etc. to use in litigation.Not sure about reforms for the court system, but patent and copyright reform, combined with restrictions on unfair employment contracts, would go a long way to improving the situation.[1] NDAs, NCAs, etc.

Massive spying on users of Google's Chrome shows new security weakness
|
A chain is only as strong as its weakest link:* developer wants compensation* browser gallery has no resources* users has no time to auditWhy as a user of Linux distribution I feel safer than installing extension? I asked maintainers, they have no answer, they don't perform audit. What if push to the gallery and update automatically is bad idea?I mean in Linux distribution maintainers pull updates, they test it and push to stable. Each distribution can block update, it makes sense for author and maintainers to easy update with reproducible builds, source version control. Distribution may audit application - it is much simpler than audit by each user. Distribution may patch application to its standards.In theory authors and maintainers can be bought, in practice it is much harder. And by itself this reduces pressure.So I believe gallery should be split to trusted and others. And browsers should allow alternative galleries. I have a few extensions I trust.What do you think?

Ask HN: I have $450K cash, what should I do to maximize my return?
|
The first rule of money is, "Don't lose it".As to what to do with it? If interested in shares, a rule that I like is to invest in companies that make products that you like. Also, hopefully, you can make some assessment about the management of the company. If they are bringing a new product to the market, can you use your expertise to evaluate that product?Michael Burry argues that Index Funds distort the market. Think lemmings. Better to use one's own judgement.Is the sun always going to be shining? No, rainy days always come. In life, you will have both lucky and bad breaks. So make the most of your lucky ones.And don't think you are a genius, when you make a lucky investment. Back to rule #1.

The chip shortage keeps getting worse – why can't we just make more?
|
Okay, so you need a $20 billion factory to put out 256-core behemoths that power servers with terabytes of RAM.But if you're GM, you don't need the latest Xeon. You need a 100 MHz single-core microcontroller, that normally sells for $2 to a hobbyist ordering a single chip, but probably something like $0.50 if you're GM and you order a million.GM would probably happily pay $20 for that microcontroller if it's holding up a $40,000 truck.If those microcontrollers cost 0.1% of what a Xeon costs, shouldn't that mean, to a first order of magnitude, the factory that produces a 100 MHz microcontroller should cost 0.1% of what the factory costs to produce a Xeon?How slow / expensive would it be if you wanted to set up a factory to pump out microcontrollers for GM trucks instead of Xeons for Amazon servers?

Debugging memory corruption: who the hell writes “2” into my stack? (2016)
|
About 15 years ago I was debugging an ARM7 memory corruption issue on an embedded target. Chip was running at 40 MHz but the instructions were ARM 32 bit instructions, but the external data bus was only 8 bits wide -- reading instructions from external NOR flash, required 4 bus cycles per instruction. So an effective rate of ~10 MHz.We were good about doing code reviews, stacks weren't overflowing, etc. So it was puzzling. Finally, just like the article said, I figured the only way to find it was to catch it "red handed", in the act.The good news is that memory locations getting corrupted were always the same.Long story short, I set up a FIQ [1] -- some of you the FIQ -- which would check the location each interrup. I forget if it checked "for" a value or that it "wasn't" an expected value, ugh, sorry... If the FIQ detected corruption, it did a while (1) that would trigger a breakpoint in the emulator. Then I'd be able to look at the task ID -- we were running Micrium u/C OS-II as I recall -- the call stack, etc.Originally I set up a timer at 1 MHz to trigger the FIQ, but the overhead of going in & out of the ISR 1 million times per second, at essentially a 10 MHz rate, brought the processor to its knees.So I slowed the timer interrupt down to 100 kHz (!!), which still soaked up a lot of the CPU slack that we'd been running with. And time after time I'd hit the breakpoint in the FIQ, but the damage had been done usecs earlier and the breadcrumbs didn't finger a victim.Then it happened. Remember, the hardware timer is running completely asynchronously with respect to the application. Finally, the FIQ timer ISR had interrupted some task's code in exactly the function, at exactly the place (maybe a couple instructions later) where the corruption had occurred.Took about a day start to finish, I'd never seen or heard of using a high speed timer to try to "catch memory corruption in the act", but as they say, necessity is mother of invention.And to non-embedded developers, this is an embedded CPU. No MMU or MPU, etc. just a flat, wild-west open memory map. Read or write whatever you want. Literally every part of the code was suspect.Good times.[1] On ARM 7/9, maybe 11, I think also Cortex R -- the Fast Interrupt Request, or FIQ, uses banked registers and doesn't stack anything on entry -- so it's the lowest-latency, lowest overhead ISR you can have. But you can only have one FIQ I believe, so you have to use it judiciously.

Postman Now Supports gRPC
|
I've posted this in a reply comment but here's a top level comment as well.The main reason I dislike Postman is not actually the web based interface, but the fact it keeps its data files to itself to try and push teams to using their cloud offerings.If a HTTP client stores its requests and configuration as a plain text file, it becomes really easy to manage it alongside a codebase and share between teams. But alas.That said, I have seen a paid version of postman be used in a company and it worked really well. But it's an expense.An alternative is what is mentioned in the top comment at this time, VS Code's Rest Client or Intellij's built-in rest client, which use plain text files (.http files) with plain text based HTTP request definitions. Those can be executed directly, without hidden functionality, and stored / updated / diffed in git.Another alternative - but this is restricted to HTTP based APIs - is Swagger/OpenAPI combined with Swagger-UI, which is both a documentation page and a demo page. The UX isn't the best, but it works very well imo.

Smartphones wiped out 97% of the compact camera market
|
This makes total sense. Most people are far better off with a smartphone. Easy to use, photos are right there, preserved in the cloud, etc.What Apple and others killed is the lowest possible segment. There's still a pretty healthy ecosystem of small-ish mirrorless cameras and, of course, DSLR, which you could buy if you need one.I really like my Fujifilm and all the nice buttons it has. But one of the key advantages is that its photos simply look different from an iPhone.

Microsoft has laid off entire teams behind Virtual, Mixed Reality, and HoloLens
|
There are two approaches to AR currently:- The Magic Leap/Microsoft approach: Use semitransparent displays to create a virtual overlay.- The Meta approach: Use cheap standalone VR with lots of external cameras, then mix camera/virtual environment.It seems pretty clear by now that, if anything, only the second works, given the success (in terms of sales numbers) of the Oculus Quest. Moreover, the latter combines AR and VR, it's not a one trick pony.The upcoming Apple headset is reported to basically copy Meta's approach, except it is expected to get very expensive and high-end. But I would side with Meta here: I don't see a big market in expensive VR/AR.A headset is like a Gameboy, if anything people care that it's portable and cheap, not that it has the most impressive graphics.In any case, Microsoft's HoloLens adventure was likely a dead end.

Ubuntu stops shipping Flatpak by default
|
If you are looking for a Linux distro, here is my recommendation. If you have the freedom, pick something that is independent + community driven(CD)/community oriented (CO) like Arch Linux(CD)/Linux Mint(CO) or which is not independent and depends on another distro's packages/infra but is still community oriented like Linux Mint or Elementary.It's not some tinfoil stuff. Community oriented or driven (entirely community driven like Arch) always listens to the community. This snap and flatpaks wouldn't happen in the first place.Use Linux Mint if you don't have time to initially set it up. Else use Arch Linux if you have initial time and patience to read. Arch is not scary like community is bad. There is a wall of text and it is intimidating. It needs time like a couple of days when you do it for the first time. But it is just about RTFM.Flatpak and Snap are unneccessary abstractions which adds a hell a lot of bloat and for what? To make a point release distro work similar to rolling release. Nothing else. So just use a rolling release distribution like Arch or OpenSuse Tumbleweed (which I haven't used but have been hearing good things. Especially since last week here in HN).But but, point release is bleeding edge and unstable!NO! They are stable versions of packages and not development streams.We seriously need to clear this confusion between a Linux distro's stable, testing, unstable repos and upstream's development branches. These two things are completely different.When you say for eg; Firefox v222222.1 with a serious security patch is in testing branch for your distro, it means it is not tested with YOUR distro which did some hacks to make it work cos it is a point release and froze your package for a point release. *AND NOT BECAUSE OF THE UPSTREAM DEVELOPMENT BRANCH HAS BUG.* Majority of the time, it is fixed already in upstream. And even if it is a bug which is new, your package needs to be an important one. Otherwise you will have to wait till your next point release update or version bump before receiving the update. This backporting and picky patching on point releases is creating a huge amount of unneccessary overhead on upstream because hacks/patching differ on each distro.Use any rolling release, Arch, Open Suse Tumbleweed, PCOSLinux, Void or a point release which uses unstable/testing branches (which ever is closest to upstream) like Debian unstable (Or whatever is being the distro's repo which is closest to upstream stable versions) which is essentially closer to upstream.These are for desktop users. AND NOT SERVERS. FYI.

"I Won The Windows Phone Challenge, But Lost 'Just Because'"

I'm not certain how one would gain sufficient attention/interest to cause an effective response, but IIRC (and IANAL) such contests typically have rather strict laws to follow; the foremost but not sole reason being, to avoid being categorized as gambling. Another being to avoid being used or misused as a mechanism to distribute payments to favored parties (one reason for the ubiquitous disclaimers that employees of company XYZ are ineligible to participate).If they are not adhering to the rules that define their contest, they may be at risk of some significant criminal infractions.

The Apprentice Programmer
|
Apprenticeships are awesome, but a lot of comments here refer to dropping out and just going it on your own, which is a lot different from an apprenticeship, which, for better or worse, we don't have here. I would recommend the apprenticeship route if we had one, but as we don't, a college degree will make your life a lot easier.And one of the best reasons to go to college for computer science is making friends who share your interests, those are the people you will network with to find great jobs, start new companies, etc. So while the classroom environment might not be thrilling, there is plenty of education to be had outside the classroom. If you are super enthusiastic, you might even get to work on cutting edge research as an undergrad in a university lab.

Do things that don't scale. Worrying about www should not be your initial concern.

Let's Encrypt: How It Works
|
How is this not really bad?Suppose I somehow get control of a machine on the same network as a server that doesn't use Let's Encrypt. I can probably ARP spoof it pretty easily. If it has a signed certificate from a different CA, I can't MITM it without people noticing. Or I couldn't, until now! Because I can now "control" the server's responses, I can easily get Let's Encrypt to authorize a new key pair giving my control over that domain. I can now generate valid certs for my MITM keys.If the server were already using Let's Encrypt, I couldn't create a new controlling key pair. The "How It Works" doesn't talk about that, but search the RFC for "recovery token". But if the server isn't using Let's Encrypt, what would stop me from doing this?Of course, I'm actually on the other end of it. To project myself, do I really have to at least register a controlling key pair with Let's Encrypt and any other browser-supported CAs that adopt this protocol?

The idea is not to change disgusting black rats by disgusting black huge insects, in fact is more complex.If we could wipe rats and restore the unique ecosystem some other species could re-flourish again.Like this fligthless bird, the Lord Howe Island Woodhen, only 15 of those birds remained in 1980 in the world, about 300 birds currently:http://m2.i.pbase.com/o6/21/489821/1/146964222.sYTnvRRL.DSC_...Or this beautiful endemic stag bettlehttp://blog-imgs-46-origin.fc2.com/a/r/c/arc6464/20111120214...this exclusive snail:http://www.lordhowe-tours.com.au/images/snail_survey.jpgsome birds will benefit alsohttp://upload.wikimedia.org/wikipedia/commons/f/ff/Lord_Howe...http://www.barraimaging.com.au/Birds-By-Country/BirdsOfAustr...http://www.avesphoto.com/website/pictures/TLTGRY-2.jpgand also this big bush cockroach:http://lordhowe-tours.com.au/wp-content/uploads/2014/06/Cock...And also other 950 endemic species

Fossdroid.com: Free and open source Android applications
|
Interesting design philosophy. I'm used to reading vertical lists, e.g. https://f-droid.org/repository/browse/?page_id=0&fdcategory=...Reading a list sideways feels bizarre: http://fossdroid.com/c/system/Intuitively I feel like my eyes are trained to flick sideways to read a short line and then down. Recalibrating to flicking sideways to read a short line, then moving sideways again a variable distance feels difficult.

There's a lot of news and 'new' stuff on the internet. And then occasionally you see something like this which is truly a fresh idea. I feel inspired when that happens!

A Response to Paul Graham’s Article on Income Inequality
|
"..the standard of living for the rich has risen and the standard of living for everyone else has dropped"Really, standard of living has dropped? Just to pick one counter-example, something like 500 million iphones have been sold in the past 10 years, and over 1 billion android devices were sold last year. Compared to 10 years ago, we've given half of the planet 24/7 access to the sum of human knowledge. Seems like a pretty good step up to me.I think what you mean is wages have fallen, but standard of living has risen dramatically and only shows signs of accelerating.

TTIP Enters New and Dangerous Stage as Democracy Is Dismantled in Secret
|
There's so much mistrust and doubt that it's hard to see a solution that would satisfy all when it comes to communicating political processes with the public. Sure, we all might prefer for the process to be open, to have edits and additions recorded together with the "who" in some kind of revision system, but would we then trust those who maintain the repository?If we do; who would then be trusted to read through the 600 page document and give an objective report on it's content? Because it has to be viewed in context, right? Not just a single paragraph used as click bait to up the advertising revenue. Who would we agree on should be considered a "real journalist"?It's tricky. We fear what we don't know and distrust those who do.A dreamy solution would be a system that allows politicians to comment on laws and voters to assign and re-assign points to those they agree with. Voters wouldn't decide laws but be able to show their support for different view points which we could graph over time and match against politicians votes.But, yeah, internet voting is equally tricky.

This is really interesting, but my heart hurts at the SEO value lost in having the main content be all PDFs. Not that there's really a NEED to have all of this crawl-able & indexable by search engines, but it could probably reach a whole lot more people if it was.

Enough with the microservices
|
As of late I've come to a new belief as to the real reason for microservices' current popularity. DevOps, deployment, and whatever-hyperopaque-cloudy-service-amazon-have-launched-this-week are the cool & fun things happening at the moment. Having loads of microservices to manage simply gives you plenty of toys to play with.Personally, the microservice-y project I'm currently working on makes me want to burn my face off every day.

The only meaningfull way to use it is with your own domain so you can change the hosters easyly without loosing your whole network of followers/friends. You can self host for sure but it would be nice to be able to just use your domain with one of the hosters for starters, is there such a possibility?

A regression is the kernel not giving the same result with the same user space
|
That's bonkers.This sounds like a reasonable definition, but quickly it turns out to be completely insane.Lets start somewhere far away from Linux, as far away as possible.Windows XP SP2 blocked access to raw sockets for non-administrators. It also blocked access to \Device\PhysicalMemory to all user-mode code, regardless of the user running it. Linus would say this is a regression.Fine, lets try something else.I wrote some C++ code that violated the strict aliasing rule. It worked for me 15 years ago when compilers weren't optimizing so aggressively. I tried to compile it using the latest GCC and got strange results. Should I file a bug with GCC? Sounds like a bug according to Linus's definition. It used to work and now it doesn't. Who cares that I violated the rules in the first place?"Now, hold on" I head you say. "We were talking about kernel and user, not compiling C++ code. That completely different!"Well, sure, it's different. But it's also similar. I maintain that the point is the same, but lets go back to Windows for a second.Lets say we have a program that used to parse the PEB.Ldr structs for whatever reason. In Windows 8 they went through a major change. This program no longer works. Is this a regression?Raymond Chen has had to deal with this nonsense enough. For example: https://blogs.msdn.microsoft.com/oldnewthing/20031223-00/?p=... And his blog is full of example of dumb programmers counting on internal, undocumented, subject to change and actually changing structs.If you, the reader, think you're very clever and say it's dissimilar because the LDR structs are user- rather than kernel-owned and -managed structs I give you the same example with EPROCESS. Take a look: http://terminus.rewolf.pl/terminus/structures/ntdll/_EPROCES...The point is that "breaking" code that does things it wasn't supposed to to should be - and can reasonably be - considered a regression.The very first example - with raw sockets - may be considered a regression, though I prefer the term "breaking change", since "regression" is a form of a bug, and this is not a bug, even if you think it's a bad policy.The other examples don't even fall under the "Breaking change" the category. Nothing THAT WAS GUARANTEED was changed. If you counted on things that nobody promised you that would remain the same to actually remain the same that's your problem.And back to Windows for a moment. Lets say someone uses the UpdateProcThreadAttribute API to set the mitigation policy on a child process it creates. Instead of only setting the bits he want (like PROCESS_CREATION_MITIGATION_POLICY_FORCE_RELOCATE_IMAGES_ALWAYS_ON to force ASLR on all modules, PROCESS_CREATION_MITIGATION_POLICY_WIN32K_SYSTEM_CALL_DISABLE_ALWAYS_ON to block win32k calls and PROCESS_CREATION_MITIGATION_POLICY_EXTENSION_POINT_DISABLE_ALWAYS_ON to prevent injection by the system of a couple sorts of plugins) he goes on to pass 0xFFFFFFFFFFFFFFFF. He wants all the possible mitigations! He's that smart!Then comes along Windows 10 with its binary signature policy mitigation and (0x00000003ui64 From what I understand the situation is very similar to this. I'm quoting from John Johansen message on the thread:It is entirely possible to use the 4.14 kernel on suse without having
to modify policy if the policy version/feature set is pinned. However
this is not a feature that suse seems to be using. Instead suse policy
is tracking and enforcing all kernel supported features when they
become available, regardless of whether the policy has been updated.The clever folks at SUSE decided to enable all the protections/mitigations/features/whatever of AppArmor, including those that didn't even exist when they wrote this stupid policy. It's completely reasonable to think that a program restriction infrastructure's new feature won't restrict programs more. Sure. If it does that's a regression.

Matrix Calculus
|
I haven't touched calculus since college and this freaks me out. I don't even know where to begin, all I remember is using mnemonics to recall rules for dx/dy or something. How would someone go about understanding this? ML is super interesting but seems daunting to anything worthwhile without understanding the maths behind it.

Machine Learning for Systems and Systems for Machine Learning [pdf]
|
Great presentation. Far as application, I already thought this might be useful in lightweight, formal methods to spot problems and suggest corrections for failures in Rust's borrow checkers, separation logic on C programs, proof tactics, and static analysis tooling. For Rust example, the person might try to express a solution in the language that fails the borrow checker. If they can't understand why, they submit it to the system that attempts to spot where the problem is. The system might start with humans spotting it and restructuring the code to pass borrow checker. Every instance of those will feed into the learning system that might eventually do that on its own. There's also potential to use automated, equivalence checks/tests between user-submitted code and the AI's suggestions to help human-in-the-loop decide if it's worth review before passing onto the other person.In hardware, both digital and analog designers seem to use lots of heuristics in how they design things. Certainly could help there. Might be especially useful in analog due to small number of experienced engineers available.

Worst Roommate Ever
|
I housed a guy temporarily who was eerily similar to this. Reading this article rings too many bells. Very good looking. Mysterious past, including pretending to have a law degree (he had taken a bunch of law classes and rambled as if he were an expert). He was being chased by the Columbians and the Jews with a truly absurd story behind it. Used encrypted phone apps. Stalking his ex girlfriend at an expensive nightclub once a week. I could go on. Things got a little old after awhile but we had quite a few fun adventures together and he wasn't (at least then) violent. I would be highly unsurprised if he eventually turns violent when he gets older and he questions his own delusions of grandeur.Moral of the story: be very careful of who you let into your home and personal life. It sounds easy until you find out the hard way for yourself. Trust your instinct if it's good, if not, always make sure close friends and family are aware of any strangers you're bringing into your life, even if they seem innocuous at first.

Open-sourcing a 10x reduction in Apache Cassandra tail latency

> We also observed that the GC stalls on that cluster dropped from 2.5% to 0.3%, which was a 10X reduction!Umm .. shouldn't the stalls go to 0, because now you have moved to C++ ? Or is this the time it takes for the manual garbage collection to occur ?
