"If it centralizes power, it’s bad. If it decentralizes power, it’s good. Build technology that is inextricable from its narrative. Build technology that will give us freedom, not enslavement."

I agree with this but technology alone won't get us there. What we're talking about here is politics and our current economic and political system will drive us further towards centralisation. This is the fundamental drive underlying our form of techno capitalism. Fewer and fewer players taking more and more control.

As individual engineers I absolutely agree that we should strive in this direction but there's no way around the elephant in the room, namely the need for systemic change.
Some of the earlier Humble Bundles had Linux users contributing about ¼ of the funds but I don't think it was ever higher than that. [0] These early bundles were also before Steam for Linux was a thing so were a major source of new Linux ports (relative to the number of available native games).

They're not trying to use Bitcoin as a medium of exchange.

They're trying to funnel people into their own centralized crypto app, where people may (or may not) be allowed to send Bitcoin via the Lightning Netowrk.

It's not that I directionally disagree with you on VC waste, but this example isn't supporting your point.
Yes, it is happening right in front of our eyes. Most tools are neutral, but the way they are being used is often very wrong. A developer may work on an ethically neutral solution, e.g. a classifier, but it a manger who decides "let's use it to automatically ban user accounts." The developer may argue the solution is not ready for that and there is a high number of false positives. The manager accepts that cost. So the technical aspect is just on the surface, deep down it all boils to simple human greed and other egoistical motives.
Because there's a vibrant ecosystem around Android with wonderful third party support, with a rich platform & ecosystem already well known & loved by many developers & consumers alike. Where-as QNX is a toolkit for building one-off custom appliances that no third party will ever see or improve or enrich. One is a dead end stuck in a niche, the other realized it had to create more value than it captured. And generally the Google open ecosystem one is pretty ok.
> news feeds filled with ads.

The OP's point wasn't about ads but about the algorithmic newsfeed. The newsfeed is designed and optimized to make you like scrolling. So, yes people do like to scrolling but hate it when they realize that it might take you 20 minutes instead of 2 minutes to get to your best friends new baby announcement. Sure, ads contribute to that frustration, but they aren't the sole reason for it.
this is a huge factor. I have found a lot of vp/exec folk are totally blind to the fat that their significant wealth makes commutes go away, and makes it easy to have a decent lifestyle AND be close to the office. This is especially an issue in SFBA where even upper-middle-class-bordering-on-rich still have hour each way commutes due to housing cost.
But if they think that they can have the second definiton without the first, they're fooling themselves. The reason Debian Stable is both kinds of stable is because they test forever, eventually put the most finely tested software into a release, then keep working on fixing any bugs in that release until the next one.

edit: your new, experimental chair just released yesterday may be stable enough to sit on, but it's nothing to bet on.
I think it's disorienting, maybe straight harmful, to view this through the lens of consumption and competition. The choice of where to live is not primarily a market-based one for most people during most of their lives, it's setting the priorities wrong.

A government should be oriented towards the needs of the people who live under and depend on it. Many people have effectively no choice to make in what state they live in, and their needs and preferences matter more than those of someone who doesn't even live there but might move there. The "competition for citizens" model doesn't really account for that in any way I can respect.
I feel like I shouldn't trust an encryption website by the British NSA not to steal my data, but given a million other people must have had the same thought, and that it's open source, maybe someone would have noticed by now.

Underrated piece. In many creative or specialized subfields, some of the best work is being done for peanuts or being given away. Prices are generally thought of as ruled by supply. demand, and product quality, but inferring the latter from the first two really only works in terms of commodities that are relatively fungible.

Preferential attachment is a large and underappreciated (by most) factor. You could do experiments by uploading the same piece of media under different accounts, both within and across platforms, and using aggressive promotional strategies for one as a kind of A/B testing. One will perform much better than the other.

Then follow up with the opposite approach; add another piece of media, and have the less popular account use the more aggressive promotion strategy. It might still do less well, as there can be a halo effect from the previous success.
Same story from Reddit World News:

They weren't profitable during a unique time period in human history where people were locked in their homes for months and mostly could only get restaurant food through delivery.

The valuation seems completely arbitrary, almost fake, when you take that into account.
Yes - and maybe "modern" isn't the best word - mean the popular genres like R&B, alt rock, etc. But it's the same problem - I don't know who the good composers are of "real" music, and I don't know where to start looking.
The restaurant did not agree to anything, at most the person ordering food agreed to something.
Honestly I've been pretty impressed with the software overall. I bought a used 2012 F-150 last year. There was something weird with the Bluetooth. I was able to update it to run the latest version of Sync which resolved the issue (it was a bit annoying to find/format a USB drive that worked). What makes this even more impressive is the newer software is designed to run on a completely different UI with a fancy screen, but they still support my older system just fine.

Doordash defines itself as a technology company responsible for connecting customers with restaurants using dashers as contractors for delivery and itself providing logistics for ordering, paying, and routing dashers.

Can you imagine what the press would do if Doordash actually sued the local pizza place because it was dumb, or filed a police report? I think it wouldn't be pretty, and the stock price could go down, and doing something that makes your stock go down can lead to an investor lawsuit.

Not a lawyer, this is not legal advice, I'd love to see a lawyer analyze this though.
Ask HN: Is MySQL 8, in 2022, a safe DB for storing financial data?
I've joined a financial startup which is in the process of building a MVP and they want to use MySQL instead of PostgreSQL as the main DB (their critical DB, the DB which will store all financial transaction data). Think checking accounts, transactions, ledgers, credit cards, investment, etc. All of this will be stored in MySQL with InnoDB.

My main concern is data loss and corruption.

I know that HN and Reddit hates MySQL and praises PostgreSQL, but their arguments make sense to me:

- Team more familiar with MySQL. It's better to use something that you know the defects and workarounds than to use something that's better in theory but you don't know how to tame it.

- MySQL has more documentation and training resources. There are excellent, up to date O'Reilly books about it from the development, optimization and administration perspectives. Just from O’Reilly there is: Learning SQL [focused on MySQL], Learning MySQL [not to be confused with the former], High Performance MySQL, Efficient MySQL Performance, MySQL Cookbook. And all of them are up to date. The official docs are also very good. On the PostgreSQL side, no such resources, there seems to be no recent good books about it - the O'Reilly book is about a very old version and the Packt ones don't count, Packt books are usually sh..t. Also, the official docs seem meh (example: the MONEY type should not be used, but you wouldn't know this from the manual [https://www.postgresql.org/docs/14/datatype-money.html], there's not even any mention on it being bad; you'd know it's bad only if you had read https://wiki.postgresql.org/wiki/Don%27t_Do_This#Don.27t_use_money

- Most complaints online seem to be about MySQL 5, which is very old and which problems mostly been fixed in modern versions, or about installations running without SQL strict mode on.

- PostgreSQL is also not immune to problems: https://about.gitlab.com/blog/2017/02/10/postmortem-of-database-outage-of-january-31/

However, I experienced, multiple times, data loss and corruption with MySQL and MariaDB, as recently as 2017. That makes me uneasy to fully trust it.

What do you think, from a perspective of data integrity and reliability, about storing mission critical financial data in *modern* MySQL? Can it be trusted? Anecdotes about ancient versions will not be useful. Is anyone here running it for this kind of workload? Is PostgreSQL still considered safer than MySQL in 2022 or has MySQL caught up in that department? The main worry is not about features or speed, the main worry is data loss and corruption.

Yes, we already have "slow AI". It's the corporate paperclip machine. It's has a strict value function; make money to shareholders. And it will do what ever it takes to make more of it.

All these ppl scaring us with AGI are either distracting us from the clear and present dangers of slow AI so they can keep profiting from it , or are just duped by silly technooptimism.
That's true mostly of "rich people" who are also highly scheduled executives. Otherwise there are a lot of tradeoffs involving comfort, time, schedule, and so forth.
The added iodine in non-kosher salt probably affects microbiological growth in undesirable/unpredictable/unexpected ways.
The +81% corresponds to the -19%. You just need to ignore the “+”. What they seem to be saying is that, while only at 81% of pre-pandemic levels, El Salvador is part of the group of countries having the best (least worst) deltas to 2019.
It reminds me of cell phone interfaces back before the iPhone. I had high hopes that Carplay would motivate the vendors to put some effort into their own interfaces but sadly that doesn't appear to have happened.

if you like Neon, then I imagine you like their database branching model? On Friday we announced[0] our 500K investment into OrioleDB, who are working on branching[1], with the plan to upstream these changes into Postgres core.

It would be possible for us to run a fork of Postgres today which supports branching, but our long-term view is that developers would prefer a non-forked version of Postgres (to mitigate any risk of lock-in). So we will work on adding branching to Postgres core in the background, which will be a benefit to the entire Postgres ecosystem.

I’m no fan of Google in some ways, but is this a problem specific to search or Google search?

I don’t see how you can avoid this unless you proactively filter out wrong information…which leads to a question of who decides what’s right. e.g. Should masks be rightfully mandated in classrooms?

As engineers, I feel like we bias for clear cut conclusions but the world is rarely black and white.

In North America, the coarse salt with zero additives is called "kosher" salt because the Jews used it to brine meat. It's generally approved by a Rabbi but even if it weren't actually Kosher, it would still be called kosher.

Some salt (table salt) has additives like iodine or anti caking agents that you don't want in your ferment because it will cause it to be cloudy (or even more cloudy).

There's also some people who claim the iodine will inhibit fermentation, but studies have shown that it doesn't have much of an effect [1].

Josh's post is excellent!

Related, a couple years back I wrote a post on the same topic: "A (Mostly) Complete Guide to React Rendering Behavior" [0]. It's longer and has more details, but fewer diagrams :) (Josh's ability to make interactive posts is amazing.)

I originally wrote my "Rendering Behavior" post specifically because the existing React docs didn't clearly spell out this kind of behavior, and I was _constantly_ seeing questions that showed people didn't understand these concepts well. For example, many folks assume that "React re-renders my component when its props change", when in fact the real answer is that "React re-renders recursively by default, _regardless_ of whether or not any props changed". There's also a lot of confusion over how Context ends up affecting renders, and I've seen folks end up in situations where setting state in an "context provider" parent component ends up rendering the _entire_ app - not because Context changed, but because they did a `setState()` and that's the natural behavior. So, I was trying to help clarify those sorts of nuances.

I can say that it's been one of the top couple posts I've written in terms of traffic and positive feedback (along with my "Redux vs Context differences" post).

The good news is that the new React beta docs [1] _do_ cover at least some of this rendering info, although it's more contextual in various points of the explanations and in less detail. I'm hopeful that after the main tutorial/API reference material is done and the docs are opened up for external contributions, that we can help add a couple pages that cover some of this rendering behavior info as well.

There's a few other good articles I've also seen covering this topic as well [2] [3] [4].

That's the part I'm talking about. The restaurant owner agreed to something in order to use the app to buy pizza.
I’ve read that comment but I still don’t understand what it is you’re computing.

It seems you have substantial amount of complicated C++ written without much thoughts about performance, and now you want to improve performance without spending too much time reworking things.

If that’s the case, I’m not sure this gonna work. You spend hours using profiler and trying micro-optimizations, but if the data structures involved aren’t good (for instance, too many pointers across things) these micro-optimizations won’t necessarily help much.

Also, I believe no modern hardware has general ways to efficiently synchronize fine-grained stuff across cores. Shared memory works, but the latency is not great for fine-grained tasks measured in microseconds or less.

To put the numbers in context:

- El Salvador has spent $104M on BTC

- They have lost about $47M on their investment

- They have a GDP of about $28B [1]

- They have an annual government budget of about $5.6B [2]

So they've blown about 1% of their annual budget on BTC. Far from catastrophic.

It's a thankless job, most of the value is extracted by the middle men (who realistically should be getting the least since they can scale to thousands of transactions like it per hour).

If I had to guess, tourism would be up because COVID calmed down a bit so people are a bit more willing to travel now. I don't see the connection to BTC
Agreed, especially on the part where people boil over to being aware of account ownership
They're investing FX reserves in Bitcoin. Their imports are not priced in Bitcoin. Bitcoin going down relative to the currencies they import in hurts El Salvador's ability to finance them. Which raises borrowing costs [1]. Which leads to exporters demanding earlier payment [2].

San Salvador has less than three months' imports in reserves [3][4][5]. Their Bitcoin experiment has scared off crisis lenders [6]. There is no good ending for them right now.

It should be illegal. It allows an unsustainable and lower-quality business to kill competitors that might actually have a working business model.

In the long run, consumers lose because they have reduced (and shittier) options, and the overall economy loses because one giant monopoly isn't going to contribute as much as a competitive market would in terms of innovations, technologies, GDP, etc.

The Bitcoin decision is single handedly marching San Salvador into a currency crisis [1]. Food and fuel are among their top imports, so that likely leads to political crisis.
