Where I work (driving a truck) they would much rather deal with a late delivery than having to pickup a few hundred thousand dollars (or millions even) of equipment and product out of the ditch. You call in with “yeah, this isn’t safe” and that’s that.

Not sure how the Amazon big trucks operate in this regard but they do seem on the sketchy side since they don’t pay a whole lot so are scraping the bottom of the barrel to get their freight moved…or so I’ve heard, haven’t actually talked with one of their drivers.
Didn't want to deal with ramifications of statement timeouts in a complex system, the failure mode mentioned (queue filling up) happened on the scale of 6 weeks, so it was very cheap operationally to set this timeout to some high value.
The real question is: how much does tutoring really helps as compared to simply prepping with free ressources?

Is it 5%? Does that mean you can't tie-break between two scores within 5% of one another? That's called a measurement error. No, this steel beam isn't 8 feet up to the micron.

So your argument is that bad developers will mess things up. I am sure most would agree with that argument. What does that have to do with monolith vs. micro-services? Bad developers will make a mess of micro-services as well.
I think massive scale is the only reason you'd really want to adopt something like Kafka. If you're 10k inserts/s or less then there's no reason not to do everything in a single big relational DB where you get the warm fuzzy feeling of transactions, point in time backups, scalable read replication, etc
You have no choice but to respect that freedom. The only alternative is to establish a tyranny of your own -- that's the only way you can tell people how to vote.

Democracies can suicide. The Weimar Republic did (though notice that Hitler never actually won a popular majority vote).

This problem was exactly what the American Founders had in mind as they shaped their Constitution. They wanted to identify the ways a government could be turned against its own people, and create barriers against those attacks. The US doesn't trust majoritarian government, which is why it isn't exactly a democracy. Items like the Bill of Rights, and features like the separation of powers, are intended both to secure liberties and hamstring oppression.

(The Federalist Papers are a fascinating discussion of all this.)

But at the end of the day, constitutional features can only slow down an oppressive majority. If a majority wants to dominate a minority, eventually they are going to find a way. The only real security for freedom, over long term, is to raise up a people that think and feel and act in those ways that are consistent with freedom.
This. The article seems like "one weird trick that message queue companies HATE" as it's utilizing, as far as I understand, some SQL semantics in a very specific way to cobble together a way of achieving what other software is designed to do out of the box. It seems fine for a toy system, but I wouldn't stake the success of a real company on this approach.

One could also use DNS TXT as an RDBMS with some interesting fault tolerance and distribution schemes. That doesn't mean it's a good idea or the best way to solve a problem.

I prefer to generalize logic at another level of abstraction, but to each their own.
The "fast plateau" is pitiful from a power delivery perspective even under tight coupling. Under looser coupling, it becomes proportionately more pitiful.
I completely agree. When I got an EE degree, most of the content was about how electric fields work. It's not a simple concept. That video was reductive to the point that it made me angry. For all practical purposes, he is wrong, and he should admit that.
It's not a trick question if you explain the trick up front.
I'm increasingly of the opinion that relational databases are absolutely the right way to build queue systems for most projects.

One of the biggest advantages comes when you start thinking about them in terms of transactions. Transactional guarantees are really useful here: guarantee that a message will be written to the queue if the transaction commits successfully, and guarantee that a message will NOT be written to the queue otherwise.

https://brandur.org/job-drain describes a great pattern for achieving that using PostgreSQL transactions.
You make a great point: there are other potential sources of conflicts besides vendor kickbacks, and they all need to be handled with care.

It isn't always feasible, but when I'm faced with a decision where my judgment may be (or at least appear) compromised, I like to assemble the details and let my team or my management make the call. Nothing in life happens 100% without bias, but I think this helps to build trust in a similar way to your disclosing of financial ties.

The industry is quite small in a lot of ways, and reputation is everything. If people sense that you aren't trustworthy, you may still be able to find work -- but everything will get harder.

I'm glad to hear that you see value in professional trust as well and take the steps to earn it and keep it.
The killing of Alex Nieto I think got the point across

It was the most obvious sign to me that the society there simply is too incongruent to work

Transplant that wasnt even supposed to be there calls cops on a licensed security guard eating in the park who had legally had a holstered taser on, transplant watches behind the bushes as the state hit squad pulls up on the guy in the fog and shoots him without question due to his uniform being “gang colors”. All while the transplant is texting trayvon martin references to his buddy about how he was looking for an excuse to handle this himself if he was in another state, and then winds up dodging police bullets while on the phone with 911. All cops acquitted.

And in case anyone's wondering what I'm talking about, back when I was about to buy my Kinesis, just about every user report I could find online mentioned that sometimes the modifiers get stuck. I really hoped that was just a coincidence, but no, my new keyboard did the same thing, and when I asked other users I came across along the way, they all said it's a regular thing with the Kinesis Advantage.

Some tried to get Kinesis to repair it but response ranged from not acknowledging the issue at all and playing oblivious, or blaming the computer, sometimes offering to replace a circuit board in the keyboard (this does not fix the problem).

There's also this 2016 web.archive.org snapshot where Kinesis is blaming the computer for missing the upstroke (what a joke to anyone who has the slightest clue of how USB or the input stack in your favorite kernel works): https://web.archive.org/web/20160221095425/http://www.kinesi...

The reality is that it's all in their firmware and looks like it took them nearly two decades to fix (if not more, I'm not sure exactly how far back the issue goes.. I think some people claim it was also happening with the old PS/2 model!) with the release of Advantage 2.

More anecdotes here, it was discussed when the Advantage 2 released: https://news.ycombinator.com/item?id=12237836

Nice keyboard but it really left me with a "shitty company" taste. And yeah, shitty proprietary firmware.

So why does Toyota sell more cars than Tesla?
Comments from owners are very important. It seems like the people who do not use FSD/own a Tesla have more complaints than people who use FSD/own a Tesla.

Anecdotally, I know over a dozen people who own a Tesla, use FSD daily, and have zero complaints. I use FSD daily with no issues. I get updates every other week or so that makes little improvements that I actually notice and feel while driving.

My biggest stress while using FSD is deciding what music to listen to.
War deaths are typically young men in the prime of life. Covid deaths are mostly old people. Not to say they should be ignored, buy what people must have experienced seeing a generation of young men die in WWII is nothing like what is happening now.
DOS/4GW and Protected Mode
Recently I have discovered that google has nuked hundreds of North Korean videos. This upsets me as needless destruction of the historical record. I wonder how people would feel if something like google was around after world war II and censored hundreds of videos of nazi atrocities. It is wrong for a public forum like Youtube or public resource like google drive to restrict content based on subject matter with very few limited exceptions. All political and war footage should be free from restriction.

Create an application for an intended audience, then schedule time where you can observe individual users using it. See what they do the most, see what frustrates them, ask them what they'd like to do and have them show you that it's possible or not, etc. Then adjust your design based on your findings. Rinse, repeat, and track your trajectory along the way.
> If that was true, apartment pricing would be flat or even trending down, as landlords would compete on price.

It is possible to have rising prices in a competitive market. For example, the automobile market is competitive and experiences rising prices. When I was shopping for an apartment not long ago, I saw several signs advertising discounts. This is evidence that landlords compete on price. However, lack of advertised discounts would not be evidence of a monopoly.
Rober is surely an entertainer first, but he claims to be an engineer rather than a scientist. The videos are more about building things which solve specific problems rather than revealing scientific truth.

Off the top of my head, I remember how the pin failed in the automatic placekicker video, how the cameras worked in the moving dartboard, how they had to use different materials to contain the large scale elephant foam...
This is pissing on people's leg and telling them its raining. There's no "cultural loading" in the SATs. English is my second language and I didn't even know Chicago was a big city until my mid-20s, but reading a lot and practicing vocabulary words is easy and cheap. New York's Stuyvesant high school has an average SAT score of around 1500, and half of students are eligible for free/reduced price lunch: https://www.nydailynews.com/opinion/stuyvesant-serves-needy-...

Poverty makes things harder, no doubt. But American parenting is just bad and American students don't try very hard. My wife comes from a lower-income white family (multi-generational lack of economic mobility) and the lack of emphasis on eduction or discipline at home is glaring. Some people, like my wife, are just naturally very self-driven and make it out. But a lot of potential gets wasted because kids are allowed to just faff around instead of being rigidly guided by parents (or, as is more commonly the case, by the one parent).
I use pass, and have no desire to move away from gpg.

I think gpg still provides "pretty good" privacy, I don't see any benefit that age would afford me with pass.

(There are sore points to the OpenPGP user experience, integration with mail clients among others, along with the WoT, have in practice been not great. But these are not things you would encounter with pass.)
I've been "lucky" enough to be in theatrical flops, and start-up flops. The mood is very similar -- the sort of constant background nervousness, and the tricks you play to keep your motivation up. I liked this piece for describing something that you never feel at the time, which is the transitory and arbitrary nature of the failure. The show that I was in which was called "the worst show on the (Edinburgh) Fringe" was directed, written and and starred folks that would go on to be well-known as very talented, popular performers; and in different combinations the folks in the start-up would be the engines behind much more successful companies.

Of course, it could have all been my fault as the common element, but I'd rather not think about that :)
Resolving error bursts from cosmic rays in arrays of superconducting qubits
This is pretty clever, and VERY "Forth".

Couple of takeaways.

First, all of the commands are Forth words, and they're using the text interpreter to do dispatch. It's like passing a string to Lisp EVAL (but vetting it first).

Second, they're using the Forth BLOCK system, which is a crude "virtual memory". But this makes things quite easy for them I/O wise. Everything is stored as absolute offsets, they MOD is by the block size, and say "give me a pointer to BLOCK N", and the system returns that. Side effects? Everything is just done "in memory". The BLOCK system does the rest (including caching and flushing change blocks back to disk). Instead of mmap, you wanted a miracle? I give you BLOCK.

Neat stuff, 600ish lines of code.

(If someone wants to read the pristine .SCR file, Emacs has a Forth Block major mode you can hunt down to make reading it easy.)
Its incredible to see the team at Airbyte with the next raise, massive $150M Series B for just an incredible product and company. I've been one of their early users and love it. Well done Airbyte team!
That is a pretty neat result, it looks like with that custom linking magic you can make binaries even smaller. Makes sense if you consider the vast majority of standard libraries isn't actually used regardless of how you link.
You do know that liveleak shut down this year, right? We are truly entering an era of restricted speech.
What would stop you from splitting the monolith into libraries and having different teams maintain those libraries? It seems to give you the organisational advantages you want without paying the added networking complexity cost. The way I see it, a micro-service is a library + networking. Remove the networking and you have a library that can be compiled into a monolith.
More context on the BMJ letter to Zuckerberg
That's unfortunate because his content used to be very good and this video seems only seeking engagement at a very shallow level, e.g. doesn't even mention transmission lines.
The offer yes, but the code does not need to be that easy to publicly access. Of course once the first person to request the source via that offer gets it (assuming they come good in that respect) it might be made more easily available.
I didn't finish the video (yet, no fault of the video, just bad timing), but I don't think it's EMI - the "pre-current" looked fairly flat, and EM doesn't like flat. I'd expect EMI to show as a spike timed to match the leading edge of the signal.
That wasn't supposed to read as a criticism of Redux. Redux was just popular enough to be the medium where people discovered that you pay a price for the indirection you need to keep view and state separate.

It won't ever be a one-size-fits-all solution and unfortunately, Redux will have to live with the legacy of plenty of users finding that out the hard way.

That being said, I think Redux Toolkit is a great improvement to the vanilla experience and I'm always impressed by how much I see you out and about on the internet weighing in on these kinds of threads. Inspiring stuff!

Can you clarify re not password-protecting keys?

If I run GUI applications, let's say, as my user -- as is the default in most operating systems -- they have general access to my files, including my keys-as-files, no? (Putting aside some minor restrictions MacOS and others are slowly making.)
Yep. The way I think about it in mainstream terms is, "Jeffrey Epstein's clients didn't just stop wanting what he was providing, someone took his place. Who is that?"
The article addresses this actually. For a language like Java, the jit is the source of a ton of it's performance.

If anyone is looking to use postgres as a job server with node.js clients, I can highly recommend the pg-boss library (https://github.com/timgit/pg-boss). Looks like it just added pub/sub too (yesterday), so I guess you could use it for that too.

Write your own. You can either learn a general purpose programming language that will do exactly what you want, and your skills will be portable, or you'll learn some ETL-vendor-lockin-domain-specific-language. Sure, they may do some things for you and make some things easier, but you have to learn their system, and in that time you could be writing your own that does exactly what you want.
> China claims Taiwan, Taiwan claims China. Both claim to be China. I don't think you understand the actual political situation.

I’m not quite sure what point you’re trying to make, but I assure you I’m well aware of the political situation. Maybe you should make fewer assumptions out of ignorance.
It probably has more to do with lower scores among "legacy" applicants, and with dodging accusations of bias against Asians.
So nobody in this discussion (nor the site) explains what "notch" means, in context.

I don't think it's just DMT that gives you this experience. One of the most "geometric" trips was from taking Salvia in a dorm room in college. Everything felt like I was in the original Tron movie. Flat surfaces seemed to go on in a plane to the horizon. Honestly, made me feel pretty nauseous.

Discussing the Chinese origin of COVID got branded because racists were using it as an excuse to attack Asians in America, including those who weren't of Chinese descent or whose families had immigrated many decades ago.

Yes, if you accuse the waitress at a Chinese restaurant of being responsible for COVID, you are racist.
I think the point of interest was 32 cores to handle what sounds like 10 messages per second at most. That's not really a ton of throughput... It's certainly a valid point that an awful lot of uses cases don't need Twitter-scale firehoses or Google-size Hadoop clusters.

If you're intending to imply that the British didn't need to hand over Hong Kong because China changed rulers, I'm afraid that's not really how the law works. And, in any case, the negotiation of 1984 (https://en.wikipedia.org/wiki/Sino-British_Joint_Declaration) between Britain and the PRC set up Hong Kong to become a PRC territory in 1997.
I'm not expressing an opinion or any information on US-originated psyops as it applies to foreign social media.

As you, I'd expect that it exists, but I have little information on the extent. I'd assume it is competent, but it isn't relevant here, since the overall topic is about CCP operations on the grounds of a US university and operations here in a US-based online forum.

If you have information of interest on US ops in foreign (to the US) social media, please post it!
> I think the majority just take whatever the landlord offers.

Taking the price offered for a particular property is not the same as ignoring prices. Apartment shoppers search for the combination of quality and price that best satisfies their preferences. I have a hard time imagining an alternative. Would that be going to an apartment search engine and simply picking the first result, regardless of quality and price?

When I go to the grocery store, I don't negotiate with the cashier. That doesn't mean grocery stores aren't competing with each other.
