There was an interesting talk in RustConf 2021 discussing the possibility of adding in-place construction and C++-like "move constructors" for pinned data in Rust. You can find it under the title "Move Constructors: Is It Possible?" by Michel Young de la Sota.

I can't find much info about this case. What is this case about? Can government threaten anything other than DNS block here? Why is Sci-hub fighting this loosing case?
I need to document that better, but rmpk ships with a "ROI optimizer". ROI is an R package that provides bindings to most of the popular solvers: https://roi.r-forge.r-project.org

But I am also working on providing custom bindings to different solvers, to be able to have more control over them. E.g. GLPK: https://github.com/r-opt/GLPKoptimizer
So the interesting thing is that nearly all home insurance policies stipulate that you're only covered for theft if there are signs of forced entry - but clearly, any lock can be picked without leaving a mark. So I'd assume either these policies are a scam, or actual real world thieves are not very good lockpickers and a good old crowbar is simply faster and easier.
SQLite is not postgres. Often sqlite dbs span only a couple of MB, ie when used in an App, and performance might not be as important as readability during debugging/development.
I just don't get why the world needs another fabless arm embedded silicon company reliant on East Asian fabs. It's not like they're doing anything better than the others.

Risc-V, special sauce, from a European or American fab, sure, it has a wider meaning.
That’s a very opinionated view from someone who’s actually read the book.

I thought the whole thing was about having a plan, and many well structured, organised teams; having a 10x programmer makes no difference at all without the rest of the things; no matter how great you are, you can’t do everything, and if you try, you’ll become a bottleneck.

I sympathise very much with wanting to staple “do you actually have a plan for how that’s going to work?” to someone in a planning meeting.

Have you tried proposing these API's on the internals.rust-lang.org forum or via posting a proposed RFC? It's not clear to me if they're sound in the general case, but if that's the case they can absolutely be added.
Not knowing what makes a hit vs a flop seems... strange.

Familiar actors and stories might help, but also things that are clever and artistically memorable (e.g. Hamilton) have got to help.

I'd also be interested to know how many shows start off-Broadway or off-off-Broadway (100-500 seats and below 100 seats as per this article), and move up to the bigger theatres: test a show in a smaller venue, see if people/critics talk about it, let supply build and keep production costs capped.

Some might argue - especially for musicals - that you can't produce "good" shows without much less in the way of production costs, but I think that could be a fallacy. I've watched enough shows and plays to know when one has good "bones" that could be enhanced with bigger sets, better actors, etc. and which are going to die no matter what you do.

Hamilton would have been getting talked about and supply not meeting demand if it was Lin-Manuel Miranda in a backroom of a bar in a frock coat, a small band and some acting students making up the rest of the cast. The bones are so good on that show - it's clever, musically arresting, compelling story arc, memorable performance from himself - that anybody who would have seen it would have told their friends about it the next day.

Some shows need to be big at the start, but they already have "built-in" audiences: Lion King trades on childhood memories of the film, it's not hard to see why it would be a success.

Spider-Man which the article touches on was always a bit of a gamble: it has built-in audience, but how many people think of the Spider-Man films _fondly_?

Contrast with Back To the Future which I saw premiere in Manchester, UK (the toughest place to test a show in the World perhaps), before lockdown, and it's moved to the West End and I'd predict is going to be huge on Broadway. Great bones, great built-in audience who love revisiting the film and story repeatedly.

Perhaps I'm in the wrong industry, but this seems so, so much easier than software businesses...
Yes for some products they might not get fired but their professional reputations are ruined. To be honest, I've seen execs get replaced (shuffled internally downward) after bad projects (large delays, overbudget). For failures in implementations in things like ERP upgrades/migrations which are multiyear and go into double digit millions, these are F500-1000 companies so executives are known failures can become public or even litigated. No one wants to be the CTO/CFO who went for a risky vendor and have it blow up. There is nothing to gain and much to lose cause failures are pretty rare but not unheard of.
Good to know. Unfortunately, since comment upvotes and downvotes are restricted features until you reach a certain level, but one's comments will probably be up/downvoted before getting there, a logical, if wrong, conclusion is that there IS a submission downvote feature, but one just can't see it yet.
Acceptance tests of aircraft are done by the pilots sent by the owner, not the factory. They do some flying and follow a checklist which is again unique to the company. It's like sending out your software for evaluation, which is in production and its evaluated by clients. You don't send testing/staging software for evaluation by clients.
I think in a sense it's a fun idea.

I highly doubt it will ever materialize, but it's ok to dream big and work towards that dream! I imagine this community might educate themselves in how to run a business like a sport club, what are different responsibilities there, etc. They have funds that they can use to invite some guests from NBA to talk about the work behind the scenes. Yeah they will never actually own a club, but as long as everyone there believes that it's the journey that matters - have fun!

This was in Germany, in 9th grade. Should have added that this was the proof of the quadratic formula.
It's really interesting stuff, although realistically, the situations in which it matters how hard to pick a lock is are pretty rare -- the majority of situations where an evil actor is trying to bypass a lock are ones where they'd be willing to employ destructive techniques instead.
looking at the last 5 years, only in 2019 I do not see any "Thanksgiving effect" :)

yes, forgive me, I absolutely did not do any formal analysis, it was just a very superficial visual check with my friends on a TRY vs EURO web plot e.g. https://www.ecb.europa.eu/stats/policy_and_exchange_rates/eu...

It looks like it is mainly more an Autumn effect, and I think the end of the Summer season (with many Tourists going home) has a strong impact
So if they have C Functions for all the things, this mean I could improve render depth? I just played OOT with mupen64 and realized that e.g. when you run around in Kokiri Forest some object like npc's will appear only when you are pretty close to them. I guess this was done in the past because of computing and rendering powers, right? Would be nice to tweak this.

One can use the packages provided by the distribution. That's how it worked since forever for things like C/C++.

For example distris like Debian even mandate that you build software for them only relying on things that are already packaged. No arbitrary internet downloads allowed during build. The build environment contains only what is provided by the stated build-dependencies of your package, which are themself of course Debian packages, and some common minimal build base (like shell and some utils).
Qualified electronic signatures are a bit stronger than "SMS and up": from your own Wikipedia link, "a qualified electronic signature is an advanced electronic signature with a qualified digital certificate that has been created by a qualified signature creation device (QSCD)". It mentions 3 requirements right after that sentence (like "data used to create the signature is under the sole control of the signatory").

As such, DocuSign is unlikely to be valid as a qualified electronic signature in Germany or other European countries.

But in all of the contractual law ever present in the world, as long as you do not dispute that it's your signature, or there are witnesses to you agreeing to a contract (even verbal ones), a contract would hold as if signed by you.
I'm in my late 40s. There was a time not too long ago where I felt the same as you. My mother died from early-onset Alzheimer's, so that spectre was not helping my anxiety about it.

Long story short, it turned out to be sleep apnea and some electrolyte issues. I now feel as sharp as ever. If you haven't seen a doctor about it, don't be afraid to. There's nothing wrong with getting it looked in to.
Clown vehicles for clown politician times. I'm not surprised really.
They should also monitor HN's submission with GitHub mentioned. Judging from historical pattern it is probably faster than monitoring traffic on status page or even twitter.
I mean the CLI flag. I suppose it's called a switch. And yes, it does support extensions if you do --headless=chrome
Generally I agree. Humans are much better at recognizing patterns than machines.

But as a counterpoint I was once working in a project where our monitoring dashboard showed an anomaly in incoming traffic. It turned out that it was an ISP problem and that we were the first ones to notice according to them.

So maybe part of the answer as to why customers are faster is that different monitoring systems are monitoring each other :)
> The vast majority of mining today uses sustainable energy (70%+)

Do you have an source for this? I remember the same number being flaunted before but it turned out not to be true. What was true was that 70%+ of miners use any amount of renewables in their energy mix.
in any event i think the op is wrong in terms of the hard part of proof of stake, private mining attacks are solvable.

the stickier issues are around maintaining the decentralized nature of pow mining and the random and decentralized election of who mines the next block. under pow, everybody does their own thing and when someone finds a block they are able to publish it without direct collaboration with other miners. the fact that the miner is chosen at random gives rise to all sorts of anti-censorship and anti-collusional properties.

proof of stake will have to emulate this, and possibly make a few targeted and carefully chosen compromises in order to emulate the decentralized nature of pow mining. it's not obvious how this will play out, but i don't think it's impossible and efforts to do so certainly aren't a "scam."
The remote has only come in in the last couple of years thanks to covid, and yes going forward if wages stay high. That's upto 70k, and note that it "depends on location". If you live in Durham you'll be on the 50k end.

Chances are by the time you're experienced enough to be pulling in that, you'll also be looking at wanting a family home rather than a small flat, which is going to be costing you more like £1k a month outside of London.
Father Knox’s decalogue: the ten rules of Golden Age detective fiction
So much of the best vaccinated country. We need another strategy for this bloody thing. It keeps us locked for years now...
The author has good points, bad points and badly explained stuff. The article is a bit confusing at best and disorientating at worst.

But I'll try to explain here, why the author thinks that PoW is magical. It's still bound to the readers, or philosophers, to pull whatever they want from this.

Proof of Work creates time. In a decentralized system, you don't have time. If time was provable, the double-spending problem would not happen. You would sign a transaction and broadcast it; a second transaction that you would sign later, will have a higher timestamp. Obviously, you can sign a transaction later and have a lower timestamp, there is nothing that prevents you from that.

What Proof of Work does, is create an arrow of time. Using this arrow of time, the nodes create a ledger (the blockchain).

The OP is arguing that PoS cannot create an arrow of time; and as a result, the PoS is still liable to the double-spending problem.
To be perfectly honest, I'm amazed how bad physical security is in the residential and even commercial US space. E.g. just the fact that deadlatches, which rely on precise alignment of door and frame to actually be locked, are a thing is amazing. The Euro-stuff has some other issues (cylinder snapping), but at least the bolt-for-locking is literally just a 8x40 mm bolt that goes into the doorframe. I've also never even seen a flat doorframe profile - not even bathroom stalls have them. Manipulating stuff on the other side becomes pretty easy if there's a 9.3/64" gap between door and frame.
Maybe, maybe not. Google was already heavily invested in java with Android. And lots of other places were too. If Oracle hadn't bought it, Google or one of the others might have bought java specifically from Sun. Or may have just let java die and be reborn as an "open source foundation" as they are en vogue now (which to some degree happened anyway, with the proliferation of the OpenJDK).
The fastest way to copy a file... on this person's Macbook.

These are essentially random benchmarks that measure something that is very much both language-, library- and OS-specific. That should've been mentioned in bold friendly letters at the top of the article, because it makes the whole exercise anecdotal at best.

The bottleneck in copying small files will inevitably be in open(). It will also be peanuts, so any noise added by the language and its libraries will be comparable to the actual syscall. You switch to C, you can get 2x speed increase. Or not. Depends on the language.

Secondly, the copying of file data will depend heavily on caching/buffering, so that will vary by the OS, by the filesys config, by the mode in which file is opened AND by the file's state in OS' file cache. If you are not careful, you run your test once, you have a warm cache. You run it again and, bam, super speeds.

The answer to the "fastest way to copy file" will depend on the file system, the OS and the nature of files being copied. None of which is even remotely covered in the post.

Edit -

Also, the results will depend on the type of storage and the file count.

For HDDs you'll see one thing, for NVMe - another, for flash storage - third, and that's without getting into working with remote shares. Ditto for the file count - 100 vs 10K vs 1M will yield completely different results and each will have its own distinct optimal copying approach. And since you are interested in doing things quickly, most likely it will in fact involve very large file counts. If so, then you can do some things on NVMe that you can't on SSD, so all these variables are also dependent on each other.

This post effectively derives its findings from one specific combo of all of these variables. May make for an interesting (if not largely obvious) read, but these findings are all but wortheless.
The lock is on the inside and the key reaches through the entire door.

yes, that's the best of course, and best is a bit far away window, not just behind your screen (which would sound perfect, but it's often 'too bright')
If the file system implements copy-on-write, wouldn't a hard link even preserve the original file if the file is edited through the original inode?

> 2 people I know have bad back pain due to car accidents. For everyone else, no clear source of the back pain has been found.

That is anecdotal and clear source of back pain in your story requires one big event. Mine experience is anecdotal too. For people I know, it was bad posture causing damage over time (when sitting mostly) and the physiotherapy with rehabilitation exercises helped.

> Fair enough, but do you have any actual evidence that actual physiological causes are the majority?

Do I need to do hunt for that since the original claim was "majority is psychological" was not just without proof, but with blatantly bad logic in it? "We excluded people where physical treatment helped" does not lead to results you can use about overall efficacy of any treatment.

> he's just frustrated with the current state of medicine regarding it and doesn't want his patients to go through a treatment believing they're actually treating the underlying condition. He will prescribe whatev

This honestly sounds like a bad doctor. He does not even makes attempt at diagnosing known physical causes of back pain. The physiotherapy/rehabilitation exercises that were recommended to me and people I know were simple and did helped. It required maybe 10 minutes a day.

I understand that there might be different causes and unknowns, but doctor who is not even trying being unable to improve any patients is not exactly an argument.
Bitcoin is knowledge of private keys. It's property in the sense that said knowledge can be used to sign transactions that transfer ownership.

I think this confirms my guess above: https://www.docusign.com/how-it-works/electronic-signature/d...

(But they are making it vague on purpose instead of just stating in plain words)
Why do people keep propagating this claim that PoW is burning electricity for nothing? It directly provides security for the blockchain. I don't disagree with your arguments general direction, just with this piece of incorrect misinformation.

LED was a technological innovation. Nothing says Bitcoin can't have those. If you want more light, you need more lamps and you need to spend more energy. I don't really see the difference here.

About every 4 years the reward for mining a block will be halved. I don't see LED lights getting two times more efficient every 4 years.
I feel like this comment comes up every time LPL is discussed outside of his context and I think it discounts the hundreds of low / no skill attacks he has demonstrated which apply to many, probably most, of the locks with recognisable name brands that are for sale in brick & mortar stores.

It took me 30 minutes to make and use a tool that he demonstrated using on a lock similar to one I own and most of that time was spent rummaging around my place trying find stuff.

Lastly, I think you got taken advantage of by a locksmith out to sell more locks and keys.

This person doesn’t have any idea how PoS works and all of the people upvoting it don’t either.

It’s very astonishing that the HN crowd still doesn’t understand blockchain after 13 years.

The article is complete nonsense because:

1. The author thinks that PoS is about having computing power. If someone thinks that they seriously don’t know anything about PoS and haven’t done any research

2. Proof of Work is 100x more centralized because 2 companies control the majority of mining equipment production and 4 companies control the hashpower including all kinds of attack vectors, instead of the around 200 entities in PoS.

3. There are many attack vectors for the PoW model of which many only require malicious behaviour of 1 person, be it the CEO of one of these companies or a disgruntled worker that is bribed with a couple of million dollars.

3. The cost of taking over consensus for a PoS network, such as Solana or Ethereum 20 requires billions or trillions of dollars worth of coins that then all would rank heavily in value

That’s why PoS is around 1,000x -1,000,000x more secure than PoW depending on how big the market cap of the PoS network is.
Probably just doesn't conflict with each other often
They stand out in all of the fluff on YouTube because it's just about the locks. No vane selfie cams.
Sorry, honestly but you sound to me like of this “European” attitude you’re fighting against. Basically you’re suggesting investing large amounts of public money (because no sane VC would invest enough capital to build an alternative YT) not driven by actual business needs (you know that you can just host videos directly on tour own server?) but instead some weird ideas about avoiding “national embarrassment”.

If European citizens valued their data enough, preferred hosting their videos on EU servers etc. and were willing to pay extra for this such a service would already exist, but they don’t. Given the current consumer preferences no independent free video streaming could compete with YT unless Google was broken up into multiple companies.
There is currently exactly one JVM in OpenJDK, which is HotSpot. It is true that there are non-OpenJDK JDKs that use some parts of OpenJDK and combine it with other code. The OpenJDK project is very explicit that only projects that are built entirely of the OpenJDK sources with only very minor modifications can use the name OpenJDK (https://openjdk.java.net/legal/openjdk-trademark-notice.html). OpenJDK implies HotSpot and HotSpot only, although in the future OpenJDK might include other VMs.

So even though the Azul Zing IBMs OpenJ9 JDKs use parts of the OpenJDK sources, they are definitely not "OpenJDK-based" in a meaningful sense. About 40% of the work on OpenJDK, and so the JEPs and issues, takes place in its VM, and so don't apply to projects that only use other parts of the codebase.
Amazing. However - I did a test where I searched for "Python cast" and got variable type casting results.

I then wanted to refine the search to the cast of Monty Python, but had no relevant tags to do it with.
