I try to understand the reasoning of a concurrent system

If two threads (or computers) can simultaneously be at any point in execution, you need to lay down some baselines for future execution. If the baseline is not met you need to Thread.yield or busy wait or busy wait and then park yourself for scheduling by the OS.

So you need to wait until the system state is valid to modify - there is nobody else modifying state. I implemented the left right concurrency pattern but it causes duplication of data. One of my ideas is to combine it with arrays of structures and structures of arrays to at least benefit from the duplication of storage for parallelism.

Once you got past that check, you do your work and then compare and swap and check that the world is still valid - there might have been someone else who was faster than you.

I'm not an expert I am just interested in multithreading and scalability challenges.

If there is multiple changes, such as a doubly linked list. I think you need multiple CAS and you need to update your guard to guard against that partial update too. How do you avoid a partial update being read? You could offload the check to a reader of the linked list to check if there is a partial update on that node.

These problems are difficult to debug but you need accurate thread interleavings that you can sort into total order which is difficult as some things are going on at identical times.

I've been reading Go scheduler sourcecode go/proc.go trying to understand how it multiplexes G goroutines onto threads M. Lots of locking going on!

I am interested in bloom Lang too for distributed programming.
The article acknowledges SIMD based sorting and states what makes this novel.
This with assumption that there is linear relation without butterfly effects, even if there are negative effects, most likely they are negligible when compared to green house effect on the planet, my false intuition tells me that power generation from wind and ocean currents would contribute to planet cooling, no idea if electricity converted to work will radiate heat faster into space then air and oceans passively.
Check out the Dole corporation to see how evil can they actually be - https://medium.com/age-of-awareness/the-dark-and-bloody-hist.... Nestle with the classic baby formula marketing to 2nd/3rd world countries, chinese milk scandal etc and probably most other multinationals are in the same league.
Is this different than TodoMVC?

A chair in the sky is great.

But in the 1990s we were travelling without moving through the aggregate of everybody's music collection that they already paid for.

In the 2000s we were using idle bandwidth to move the distribution cost closer to zero than ever before.

In light of that, I wonder if in a decade you'll be praising an uncomfortable sardine can that drags us across the desert with better than 25% departure delays.
Yes, Secret Chat's awesome UX of requiring both recipients to be online and the inability to use it on desktop.
To prevent bots from causing bandwidth costs to be insane?
I agree AVX-512 is not exactly widespread on client CPUs but as akelly mentions, it does exist (e.g. Icelake).

What we do is dispatch to the best available instruction set at runtime - that costs only an indirect branch, plus somewhat larger binary and longer compile time.
A tech podcast interviewed someone recently that does SWE and farming in Germany. Sounds exactly what you’re looking for, they ask him most of the questions you want answered:

I am always amazed at the algorithms re-implemented using SIMD. One of my favorites is the Striped Smith-Waterman approach used for sequence alignment. Does anyone have any good resources on learning to use SIMD? I've found it heard to make the "plunge".
Anecdotally I’ve personally seen a lot of “Bitcoin accepted here” signs while traveling around America. It’s not ubiquitous, but it is there. Hell, I bought a plane ticket with Bitcoin way back in 2014 for a family member to come see me.

I’m not sure if you’ve ever heard of the “lightning network” but it uses some really clever cryptography which allows people to send/recv Bitcoin almost instantly, with finalized settlement done on-chain as a normal transaction when the payment channel closes https://en.m.wikipedia.org/wiki/Lightning_Network

The other thing about payment finality is that thanks to blockchains with smart contracts (so not really on Bitcoin) things like escrow become pretty simple to conduct. You can write programs to enforce exactly how an exchange should work (“only release payment after proof has been posted to the chain”), and both parties can have confidence that no one is getting taken advantage of because they’ve agreed to immutable rules beforehand - to me that’s a super powerful primitive to build neat stuff with.
I really liked the story of Celeste, not super deep but the gameplay is super smooth, and the art is gorgeous. It has the perfect balance of being difficult but not difficult enough to get mad at (except a few levels...).
As far as I know, the database is owned by the USPS, and they can't do their job _without_ that information. You can dislike Brave for buying access to the information, or dislike USPS for selling said information. But the information is already collected by USPS so they can do their job.
Also remember: these were the same buffoons that put Cardinal Pell in prison on trumped up charges of child sexual abuse until Australia's own High Court unanimously overturned his conviction. I'm all for going after actual criminals when there's real evidence, but on this Australia can pound sand.
Too bad Android emulation isn't good enough to avoid this.
the other way around is also true, the climate affects the flows

seems like an interesting possibility to recapture some of the loose climate energy that we want to pare down
As much as I enjoy blaming the Trump administration, this story didn't actually name Trump/Holder/Pompeo. This all happened under Obama's admin with Comey

Your point still stands though regardless
BTW in 2004 and in 2014, Ukrainians kick away TWO authoritarian presidents, and Russians from 2000 live with putin, they cannot organize even strong protests, and this is one of reasons for dark envy, and why Russian behavior in Ukraine so inhumane.

- Russians centuries raised as Nazi, in belief that they are superior nation, who control largest territory in the world and interfere behavior of British empire.

They even invent theory, that they are Great Russians, but Ukrainians are little Russians (for other nations also created such pseudo-scientific namings and narratives), and they use this theory as grounding to demand obedience from other neighborhood nations.
Kentucky Route Zero is beautiful, weird, and more or less non-violent. However, its themes may be too mature for your kids, depending on their ages.

Pop Culture Happy Hour from NPR has done a couple video game recommendation episodes. I bet you'll find some suitable recommendations from them:

The same can be said about solar panels. An enormous amount of heat is no longer hitting the ground.
Yes, Github has recent history. http://www.aaronsw.com/2002/html2text/ has all the initial release notes.

By the way, it is interesting that Aaron implemented most of his ideas in a single file. Like web.py.
Having certain ties to the US (such as a US phone number or regular transfers to or from a US account) are considered "US indicia". Having them triggers a requirement (thanks to FATCA) for the bank to verify your status as a non-US person. Usually this means furnishing a W-8BEN to the bank. This applies even if you're not a US citizen and never set foot in the US.
It's short for ex's visual command which would allow you to interactively edit text rather than edit with commands. You didn't have to type the entire command to get it to work, just the first two letters (though the long form did work).

vi was originally just a command that forced ex to open in visual mode.
When I interviewed at Coinbase 6 years ago, the interviewers felt egotistical and borderline incompetent. After I’d interviewed, they decided to change the open req to a different role.

By “egotistical”, I mean that the interviewer clearly believed he knew more than he actually did. It was that “I’m hot shit” vibe. I have worked across several roles in this industry over the last 20 years, and there was clearly inexperience on the other end of the phone.

That told me everything I needed to know about the company, and I was happy to move on from that experience.
I think it would interesting to have a power consumption comparison as well.
That list above is what I was mainly thinking of. Here's a few more with great storytelling, done in various ways (sometimes non obvious but they all have a story to tell that kept me hooked)

I don't recall any physical violence in the following games, although psychological violence can be very personal and some may run you in a mood or facing events that can be unsettling at times. Some of these have neither.

Gone Home
The Swapper
Fez
Day Of The Tentacle
VVVVVV
You Have To Win The Game
Braid
Shelter 1 & 2
Her Story
Portal 1 & 2
Thomas Was Alone
One Night Stand
The Stanley Parable
Antichamber
Carto
RiME
Oxenfree
Never Alone
Life Is Strange

Soma and the Amnesia series could be of interest as well. I seem to recall it's all about fear, but not violence.

Mirror's Edge has punching but you don't kill anyone and you can avoid most encounters, with parkour style. Definitely not COD.

Limbo and Inside have gore but clearly not the COD one.

While enemies have guns and the setting may subscribe to "war-like", I seem to recall you can also complete Deus Ex Human Revolution Director's Cut without lethal action (in the original non DC bosses have to be killed) which is rewarded with an achievement at the end of the game.

Heavy Rain is also a great game with original mechanics. Don't attempt to play with PS Move, use a controller.

Some of these are good for kids, some aren't, depends on kid age and how you want to raise them!
I'm not pretending to be an authority on anything, or representing anyone but myself. You can't just pick and choose which parts of society you want to comply with. If you do, you get incarcerated. As a direct consequence, interfacing with society's infrastructure is a soft opt-in, which will result in your incarceration if you don't live within the bounds of that society. So it's not a stipulation, nor do I require any authority, nor do I need to speek for anyone, when saying it, since it's a necessary component of the theoretical.
That's fascinating. Do you happen to have a link to a study describing how deep root systems can transfer up to half their glucose in the soil?
Even if AVX512 was entirely constrained to server hardware (it's not), how would it be contrary to the public interest for open-source software to take advantage of those instructions?
I agree. I think the grandparent is maybe describing an ideal state, but in practice most "DevOps" and "SRE" positions I see go by on job boards are for either sysadmins who can do some automation and infrastructure as code, or possibly devs who know how cloud infrastructure and networking work, depending on your perspective.

If you're lucky the hiring manager might have at least read the Phoenix Project or the Google SRE books.
The Private and Open Voice Assistant
"California style cuisine" focuses on local ingredients, if you had a "California style" restaurant in Ireland it should focus on things like beef, grains, cabbage, carrots, etc. but it would be prepared differently.
It's cartoon violence, but the gameboy ones I played had plenty of violence.

Vader can force choke other minifigs to death.
The vast majority of users of Telegram come from (and reside in) a country whose jurisdiction you probably wouldn't trust. Most of its developers, too (though they have relocated).
Why would someone who rejects society care about society's laws?
He is very active in local politics. He got letters from others too.
With us heading into a huge global grain shortage this seems like a very bad idea.
My friends and I have a seed-investment fund that we needed to be low overhead since we're all running companies. The Delaware process was fairly low-overhead. Some things needed to be notarized and it was a pretty easy process to get a virtual mailbox and everything (notarize.com was in the loop and they're neat!)

Sorry it isn't directly against your constraints but we are foreigners in the US so I thought I'd mention it. More information is always better :)

Good luck! Eager to hear how it goes.
100%.

I have filed so many radars against Music.app and they’ve never been fixed over the years. IMO, It’s gotten significantly worse since iTunes got broken apart in Catalina.
As someone who spent some time in Oracle land: MariaDB can't hold a candle to it, but postgresql comes close.

Some things better in Oracle vs Postgres (and I might be dated on my postgres knowledge):. The active/active failover story of Oracle is better with RAC. Auto vacuum horror stories don't exist in Oracle.

Also pro oracle: The 'enterprise' ecosystem is better. Everything enterprisey integrates with oracle, postgresql is still a toss up.

But at the end of the day, I still vastly prefer postgresql. The endless list of weird idiosyncracies and weird limitations in oracle makes you always feel a bit dirty, compared to the relatively clean syntax of postgresql. In oracle land, it is common to wait 1 major version before using new features, because they are unstable when released.

And dealing with oracle support is hell with an additional bonus of pain. They take months for a simple bug fix. They won't admit a bug exists, then call you at 3AM and give you a patch written 2 years ago.

Oracle licensing is a game for advanced poker players. It will be expensive. Then you negotiate, walk away with a 40% discount, making it more expensive than competitors, and find out later it was still a bad deal. They'll interprete standard words like CPU in a slightly different way in their licenses, and finding out in an audit will cost you a lot. Licensing is a never ending drain on your time, and you will loose their games in the end.
Alternatives like take homes, pair programming etc… don’t demonstrate that a company doesn’t care who they hire. I mean sure it could, but it could also demonstrate they don’t cargo cult interview practices.

Other industries don’t hire this way for anyone but fresh grads, and most don’t even do this for them.
Vegetable garden is on 300m2. Fruit trees on 500m2 currently expanding it to another 500m2 and planning to add chicken, dwarf goat and geese. 1.3ha is a meadow mown by a farmer to make hay bales, in exchange for 2 bales. My plan is to slowly expand on the meadow to make guest houses (for tourism and yoga retreats for my wife)n fruit trees and animals. Rest of land is composed of buildings (main house, guest house, yoga studio, and other dependencies) and garden.

I am not a farmer, and I don't enjoy spending my time cutting grass, that's why I am planning on adding small animals as they eat grass all day. I am trying to minimize the "human" part of the land, so I am using basic thermic tools (mower, brush cutter...) to cut grass and trees.
I can confirm Coinbase interviews are difficult. I went in relatively confident and still failed.

Looking back, it would appear I got lucky since we all know new blood is the first to be dropped come a downturn. Well, maybe potentially not lucky since I recently jumped ship anyway, but it is not crypto or startup so risk level is lower.

To your point, I agree. As an applicant, I would be really aggravated if I passed on an offer, because I received and accepted offer from another place ( and that another placed rescinded offer afterwards ). Can I assume there will be some lawsuits over this ( in that case there seems to be an incurred loss )?
There is also nothing preventing intermediate distributors outside Tunisia from blending and repackaging that oil with cheaper oils. Or from such scoundrels from outright lying about the country of origin.

No one has come up with an unbreakable or unforgeable supply chain for these goods, which is why counterfeiting is still such a problem.
It’s june already so no it wasn’t. The writing was on the wall in November and Fed had clearly telegraphed their intent that this is going to happen
Works out - because southern Europe has great weather!
Venezuela is not only almost completely dependent on oil exports (extreme price fluctuations) but it's also not agriculturally self sufficient. It's not the only country with those problems, and they're not insurmountable problems, but it requires good economic planning to be able to handle downturns in those conditions, something Venezuela didn't have.

Argentina, on the other hand, has somewhat more varied exports (though soy and corn products are a large portion) and is agriculturally self sufficient. Unlike Venezuela, which had a "export oil, import everything else" mentality, Argentina has a large degree of economic protectionism and so they do have other sectors to help supply domestic demand to some degree.

There's obviously many other factors, but those are the largest ones in my opinion.
Thank you. I hadn't realized that the 4th edition was now free to read online but this isn't exactly the gotcha moment you imagine.

It was recently made free 8 months ago in a blurry unpleasant to read format a decade after the language launched after everyone else ate their lunch.
palo alto is an extreme environment.. surely the readers have to know that
This has a few big improvements over Aurora. Aurora has scaleable disk, but is still 1 big master Postgres instance (and optional read replicas), with all the drawbacks that comes with in scaling speed, cost and failure modes. This appears to be a distributed many-peer-node Postgres, with an all new abstracted distributed storage layer. This allows a lot of neat things with scaling/cost, and innovation on the storage layer (like their writeout to S3). Basically this is true serverless postgres if the claims are correct, and that's amazing.
The government only has a monopoly on legal violence, but violence is beside the point. (And never mind that a bad government could simply steal the data or compel a corporation to hand it over.)

Imagine living in a state where abortion laws now allow individuals to sue other individuals who have had abortions. A corporation could use grocery data to find and sue individuals who are likely to have had an abortion. The analysis would be a bit more complex than this, but just looking at grocery data, scan for people who bought pregnancy tests, bought fewer tampons than usual, and aren't buying baby food a year later. No violence, totally legal, and absolutely devastating to the individuals involved.
It is very difficult to believe Brian Armstrong was cynically cashing in on what he perceived as a Ponzi ten years ago when he founded Coinbase (he posted an ad for a co-founder here on HN).
And I disagree, because virtually every successful resistance to police or prosecutorial misconduct (and there are many!) comes right down to a successfully argued fourth amendment violation. The fourth amendment is, quite frankly, the single most powerful check on law enforcement power in our society. And people who claim otherwise really need to spend some time resisting governments that don't have an equivalent.

But in this case, as I mentioned, the fourth amendment is silent. This arrest was totally OK (or would have been, had it not been spoiled) and doesn't represent any kind of government overreach at all.
I got one of these yesterday. I'm uninstalling Brave and going back to Firefox
The CPU has a certain upper bound on power, TDP. That limit is independent of whether it is reached by executing scalar code on lots of cores, or SIMD on a few.
One little-known fact is that out of order CPUs burn lots of energy just on scheduling instructions, ~10x more than the operation itself. SIMD amortizes that per-instruction overhead over multiple data elements, and actually increases the amount of useful work done per joule. We're talking 5-10x increase in energy efficiency.
There is value in a global blockchain with the level of participation of crypto. And sure there are scams, there are scams in the real economy too.

Ponzi is not an acronym for “I don’t understand its value therefore it’s a Ponzi scheme”.
Fuck it, not even Ceausescu was doing this (or something similar to this) in communist Romania, and I grew up under Ceausescu as a kid, I should know. The worst that was happening from this point of view was maybe an older neighbor lady stopping you on your way back from the grocery store and literally going through your purchases (yes, kids were sent to the grocery store to do small purchases), but nothing more than that (and, even then, we, as kids, knew that what those old ladies were doing was wrong)

Which begs the question: how come today’s Norwegians are ok with this? How is this normal in a liberal democracy? Is this what modern liberal democracy was all along? I.e. a dystopian State infringing more and more on one’s basic liberties, all in the name of the “greater good”? That’s nuts.
The reason for 10% is because (a) tithing isn't that hard on most people's finances and (b) it's a nice round number, memetically strong and aesthetically satisfying. Sure, it's arbitrary -- but it's arbitrary in a way that was designed to appeal to as many people as possible without making them feel like they have a moral obligation to make arbitrarily large sacrifices.

That's it. There's no broader philosophical reason for why 10% is Objectively Correct. This is driven entirely by practicality. (If we had twelve fingers, the number would probably be 12%.)
Nah, when someone calls it an unencrypted messenger, one can assume they mean it's unencrypted on the server, as in-transit encryption is ubiquitous and thus a meaningless signifier.
I think it has to do with gut biome somehow. I've seen excellent biome diversity scores from other people on the diet, but in my case it's from repeated experience with gradually eating more and more fruit (and nothing else), not necessarily large quantities even (though I did ocassionaly eat quite a lot apples).

I haven't really tried with vegetables (not interested taste-wise), so it might be the carbs / fruit sugars that weren't great for my gut biome, which I suspect is messed up as it is for many people nowadays.
> otherwise, just ring up your massive meat order one steak at a time

David Foster Wallace's unfinished novel "The Pale King" (which is set within the context of an Internal Revenue Service Regional Examination Centre and the people working there) contains something like that – at some point a supposed 1977 progressive sales tax experiment in Illinois is mentioned, which of course went horribly wrong and caused lots of chaos because people began splitting up their purchases in order to stay within the lowest tax band, and so it had to be repealed again after four months.
Not far off Burn After Reading
Beanie babies are actually a tangible object though. :)
I wish I could forget this game and play through anew.

It does contain spoilers but the games creator wrote a masters thesis on this game[1].
