My experience with hardware RAID cards (LSI, PERC, etc) is vastly different than the recommendations you heard.

I have been running production servers with LSI hardware RAID cards for the past 15 years and have not experienced the items you note. The only thing I did experience was a bad RAID card (solved by replacing it with a similar LSI model).

To contrast your "problem" list:

* Compared with MDADM (mirrors, RAID-5, RAID-6), the LSI RAID cards tend to be on par as far as performance (esp with BBU)
* A failed drive won't prevent the array from coming on line (in my experience)
* All my servers have battery backed RAM; never had an issue with slowness or high-latency. Can't say the same for ZFS.
* Never, ever had a problem with metadata on the disk. Not sure why this seems to be an issue
* LSI cards have pass-thru mode and can easily be used with BTRFS/ZFS. I have done lots of tests; never an issue
* LSI cards have their own "patrol read" mechansim to scan drives for bad sectors and send alerts when something seems wrong

On a positive note:

* Hard drive failures are truly plug-n-play. Send a tech out to the cabinet, spot the RED light, replace drive. Done. No OS work, no console, no crash cart needed.
* You can logically divide the drives using the RAID manager tools just like Linux MDADM, ZFS, BTRFS, etc. Easy.
* You don't need the specific card to replace a failed card. You just need a card that can read the metadata on the array to bring it back to life.
* Lots of monitoring scripts available in the wild to get RAID stats, rebuild times, etc.

I am not saying hardware cards are indestructible. But, all in all, hardware RAID cards are solid devices that have been in many, many production servers all over the world. I certainly would not dismiss them in favor of ZFS RAID (which tends to be slow for many operations). Pick the best tool for the job.
Clean up the mess? How do police clean up a homeless mess? I've never heard of this happening.
SBF literally stole billions from a bank account. Not a very subtle crime.
This seems like it would be a great way to make long lasting milk which doesn't taste like UHT milk. Apparently it does work, but perhaps regulation hasn't caught up with it yet [0].

Edit: Seems that it may not be as effective in milk because of a pressure resistant enzyme [1]

Maybe this could also open up more avenues for money.
The death of passenger rail in the USA is actually really pointless and sad. E.B. White discusses it in one of his essays. He writes it far better than I can, but the gist is that it used to be that every freight train that carried mail, which was virtually all of them going most anywhere, had to hook up passenger cars too. The railroads lobbied to get this requirement dropped insisting that it was so expensive it was putting them out of business. Pure lies, of course.

I've head there is a bit of a relict though. My understanding is that if you own your own passenger car and pay the switching and storage fees, then you can hook onto a train going wherever for a standard rate.
> Maybe this was the only way to ensure he testified

Nope, it doesn't make any sense to arrest him if the goal was to force him to testify in front of congress. Once he is placed under arrest then I'm pretty sure the house cannot make him testify if he is in custody, he becomes at the mercy of a judge and I imagine bail conditions will not allow him to talk in public about the case either.
Instead of cooking up hypothetical circumstances in which Musk is a hapless victim, how about we examine the actual situation where he and others are insinuating that this Roth guy was promoting pedophilia (he wasn't), and the fact that Twitter isn't consistently removing obvious and explicit death threats.

Edit: for context, here's a collection of threat examples from a fairly well-known researcher who regularly catalogs botnets and fake follower accumulation on Twitter: https://twitter.com/conspirator0/status/1601681990071521281
Yes, but you have to go deeper.

Why is nooone willing to increase the level of supply unless they can make a lot of money and so optimizing for luxury housing?

Because housing is expensive to build.

Why is housing expensive to build?

Because there is a lot of red tape and regulations.

Why is there a lot of red tape and regulations?

Because of existing home owners lobbying for it to resist the increase of supply.

Why are NIMBYs fighting more housing?

Because more housing decreases their own house prices and investment.

Why are people so preoccupied with their house prices - is it greed?

No, because for an entire generation of people, their house price is the only retirement investment they can rely on.

Why?

Because the social safety net in North America has eroded and if you disrupt the housing supply you're just going to have a different problem of a retiring generation that we cannot take care of.

People were complaing about how upgrade to 10 happened without consent. So 11 requires TPM, if you disable it, they definitely probably won't upgrade you to 11 when you close the notification.

So we make small dinosaurs?

What about not bringing back dinosaurs but changing the dna of say a chicken to resemble that what we'd consider to be a dinosaur without it actually being any historically known dinosaur?
Madoff was also planning to cash out and distribute the money he had left to family and friends. The FBI probably acted to prevent that
Deep Learning training is usually I/O bound these days. Definitely on GPU side, I believe the same thing on CPUs. Not clear if many people are using CPUs for the DL training, though. CPUs are used mostly for the inference, when response time is not critical and models are large (with large RAM requirement).
This is quite brilliant . I am sure most of the democrats who could afford to buy a Tesla has already done so and stuck with it - so Musk is now targeting the remaining half of the population ie the republicans. With deep partition ship in the American social consciousness , this may be the only path forward where to sell a product quickly the company has to align itself with one party or the other. It does not matter much if they change affiliations down the line - public memory is very short. From a moral standpoint it is really bad but then who cares?
Social media isn't all there is to the "tech industry"
Maybe the sports model doesn't apply at all, and it's arguably pretty unimaginative to try to force the proven sports model onto computer games.

Is there another way to play as a collective experience, and to monetize it (not that I care to monetize it, but obviously some do)? Or another way of approaching the issue, do we need more than what's already in multiplayer online games? Should we just add something to those that is more of a mass collective interaction?
Globalization as in trade and interaction bringing people together has been going on a long time, maybe a couple of thousand years with the original silk road and boats trading around the med. There's a bit of a blip at the moment especially with regard to Russia and China going a bit warlike on us but I think the long term trend is intact.

Perhaps, but fuel synthesis processes usually have to run continuously. They can't really start and stop intermittently based on momentary solar power availability. Those plants will represent huge capital investments, the workers will have to be scheduled in advance, and they'll have to make fixed delivery commitments to customers. Some form of carbon tax on fossil fuels might make this more economically viable.
I can't imagine why he wouldn't flee.
If i was committing ~9 figures worth of fraud, I would have huge stashes of 1oz gold bars buried in countries without extradition like Vietnam and venezuela.
He seems like he had no exit plan thought up.

Madoff got 150 years in prison, and i dont see any reason why SBF would get any less.
Human intelligence can be controlled, humans can be locked up. Human intelligence is also restricted by our species' cognitive capacity. General AI can theoretically outperform any human's cognitive ability, it's perhaps likely our limited cognitive ability would not be able to control something that is orders of magnitude more intelligent than us.
Tianeptine isn't a recognized drug in the US (though it is in Europe, iirc), but it's been available from online RC/nootropic vendors for years. It's not the first time something like this has happened, either - a while back it was found that several brands of "herbal viagra" sold in gas stations actually contained pharmaceutical PDE5 inhibitors.

Make a quick buck and run, I guess.

Edit: apparently tianeptine is a full mu-receptor agonist
Hopefully we will see this as a powerful turning point, heralding an end to cryptocurrency, with all its false promises of financial utopia.

Turns out it was nothing more than a series of scams, and the ensuing court cases will prove this beyond a shadow of a doubt. This entire edifice will come crumbling down, and take this entire sordid industry with it. One can hope.

It's an island. Tough to get off even if not arrested. I'm sure if he tried to get on a plane all kinds of "problems" would have appeared (computer not working, ...) If he tried a boat, "oh look, it's leaking oil, we can't let it leave and pollute the waters".

I can even see the titles if he left "Did he bribed Bahamas officials to look the other way?" ...

I share the same feeling as OP. Open source games can essentially live forever and others can pick up where the previous entity left off. For instance, starcraft 2 still has big mass of players, even though it's on life support (servers die sometimes, bugs go unfixed for years/forever, maps are not updated as frequently anymore, etc).

That's one aspect, the other aspect is that the opensource base can end up becoming the reference implementation of a genre. It can become a more sustainable environment, where people are trying to improve the game (and get paid through the organisations that run tournaments and such) rather than create a competitor.
Thanks for the link, interesting to read.

"The issue as to whether the clause can be removed is still pending" -- that was in Mars, is it still pending now in December?

My guess was that indeed it could have been you :-) (which it was) since I couldn't think of anyone else.

From the report you gave, the first paragraph under the heading "Primary Cause of Homelessness":

Widespread homelessness is the result of a severe shortage in affordable housing, a widening gap between rising housing costs and stagnant wages, and an insufficient safety net for individuals with disabling conditions. Though these drivers are structural and systemic, individuals often have one or multiple major events or factors that precipitate their homelessness. An inability to secure adequate housing can lead to an inability to address other basic needs, such as health care and adequate nutrition.
> Like any investment, earlier you are, better your returns are.

The big caveat here is "earlier" means "founder early", not "employee early". By and large, unless you have the same founder-class shares and shareholder rights, you are participating in a lottery just like the founders, except you're even more in the dark than they are, and you are taking on even more downside and less upside than they do. By design.

This might have been tolerable back in say the 80's or 90's when losing a few years of your life to a startup might not have an appreciable effect upon your future lifestyle, and everything was still so new that the experience gained still could cover a noticeable fraction of the entire field's domain knowledge. But I don't advise it for young adults today any longer when even a few years makes a noticeable impact upon a future acquisition timeline of housing/shelter and retirement, with rampant asset inflation under a functional gerontocracy for the foreseeable future. I don't see how the numbers pencil out at this time for employees, even taking the probabilistic distributions into account.

I sure would like to be shown an alternative win-win perspective though, as I think startups are nifty. The startups will be fine though, as there will always be starry-eyed youngsters swarming to startups no matter what, but I wish there were better outcomes with how far the industry has matured and accumulated wealth of all types, than the same dilutive structures we see over and over today. It would accelerate the rate of change.
If requiring moderation made it impossible to operate UGC sites at a large scale, wouldn't we expect to see more competitors and choices, albeit at a smaller scale?

For example, a small group of friends could easily run a social media network for a small town of a few 1-10ks. Tens of people would be capable of moderating it, especially once the bad apples are identified and banned.

There would obviously be some disagreement about issues like admission criteria or what it means to be a "bad apple", but your neighbors could start a competitor just as quickly and cheaply, and you would both be legally responsible for the content that you allowed to be published.

Many small blogs operate on a manual approval process for comments, and it works fine on a small scale with a spam filter or two to speed things up. Why shouldn't we expect the same to be true for social media, if the cost of scaling manual moderation couldn't be ignored by unscrupulous parties?
People like to think that their motivations are a result of intelligence. They assume that any intelligence will share those motivations.

Actually, most human motivations are shared with the crudest of life forms and have nothing to do with intelligence.
they "own" it.
In the 2000s, what in retrospect seems like obvious con men selling random number generators got pretty far up the national security chain of decision making:

“Repeaters of association” is such a wonderful and spot on description for LLMs, but it’s also what makes the output so believable, whether or not they’re actually accurate in a given case. In policing and national security, there’s a lot of money and easy secrecy, and while I agree that the “escaped AI in the wild” seems hard to quite fathom mechanically, it seems equally hard to fathom it not playing an unwitting sidekick on some truly terrible scenarios.
In the future we can simulate growth and metabolism of a specimen, when we have its DNA. So we'll at least have a biologically accurate simulated Jurassic Park.

That's also when we can debug consciousness, given that our simulation is accurate enough. I have no idea how many years we'll have to wait. Maybe 50 years?
How did you discover these loopholes in the first place? Did you work in the finance industry or an ATM maker or something like that and just figured it out?

At the basic level the artist chooses what to include and what to exclude from their base? Similar surely to the curator?
Places like Manhattan and SF need restaurant workers, teachers, daycare workers, janitors, etc. Jobs that don't pay anywhere near enough for them to afford to live anywhere near them. Somehow we need to provide these workers with housing that they can afford so they can do the work that needs doing in those areas.

Everyone in production reproduces this. Intentionally or not, everything on a long enough timeline will suddenly lose power.

I'm sorry to offend what is otherwise a decent filesystem, but I, and the systems I'm responsible for, will not use BTRFS with RAID and this characteristic.

There's a lot of qualification there, read it again.

I would much rather let the journal replay and do its thing, than rebuild the array. Something every alternative offers, consistently.

BTRFS RAID has routinely burned me every time I have given it the opportunity. It hasn't survived nearly as much as the other test arrays.

I'm fine discussing filesystems, benefits, and all of that - but I can't entertain it when you try to make this so heated.

These are anecdotes from reliability tests I've been doing... I'm sharing them so that they can be considered.

You accuse me, while opening like this? At least my anecdotes weren't insulting.

edit: To add, this isn't something I've kept secret. I don't know why you say that. Have you read every communication I've written?

I can show you screenshots that span the last three months discussing this exact situation

I haven't reported it upstream because I have better things to do; ship.

You might see this, but hopes aren't high. This is about the response I expected. It's an extreme edge case, but it consistently cuts.

The filesystem we use is incredibly uninteresting. By design.

I find it utterly hilarious you think I'm the only person who has had issues with BTRFS RAID
I honestly find it to be really boring. The generated code/stories etc. are either trivially simple or just bland/boring. Wake me up when an AI produce something truly wow.

Having said that, I am really impressed with some of the art generated by AI’s. The rest? Not so much.
You're right. I was thinking of the 3 months between the arrest and the sentencing, not the collapse and arrest. You'll have to forgive a memory 13 years hence. ;)
Ask HN: How have you used your [tech] skills to improve your local community?
I'm looking for ways to put my talent/skills to good use, and the most obvious route for that (short of switching companies and joining a non-profit) that I can think of is to get involved/"give back" in my local community. I'd love to hear if anyone in the HN community has anecdotes or ideas from which I might draw inspiration.

I find the best technical training is centered on a use case and has ample hands-on material to go with the concepts. Additionally it should curate what I really need to know so I’m not spending my time following bad leads or going down the wrong path.

Ultimately training should be associated with an outcome which accelerates the time to achieving business value. Good training pays for itself this way.

I think it is important for two reasons. First, the primary purpose of RAID is to improve availability of your data, such that you can continue operating in spite of a hardware failure. If the RAID feature of btrfs has serious data loss problems, then it is taking a feature that is supposed to increase availability, and instead decreasing it. It is like an UPS that is more likely to cause a power outage than to protect you from one.

The other reason is that the atomic snapshot feature, and ability to easily transfer diffs of snapshots makes a wonderful foundation for incremental backups. But if I can't trust the filesystem to avoid corrupting my data, how can I trust it to avoid corrupting my snapshots? Hence I can't trust my backups. So I need to go back to a more independent backup processes like rsync.

With those two features gone, my whole motivation for using btrfs over simpler file systems like ext4 is gone, so why bother.
This is a good reminder of Google's advertising economies of scale.

It doesn't surprise me that Twitch is struggling. TikTok could suffer the same fate as Twitch: their payouts aren't as good as YouTube (Shorts) on a per view basis. The only thing that's keeping TikTok in the game is their reach. Once reach hits parity, I wouldn't be surprised if TikTok succumbs to YouTube.
I was constantly looking for flights. Cheap flights. It was my obsession (I've visited 80 countries pre-covid) and friends came to me for hacks/cheap flights.

So I started a website/blog/newsletter. Then I added a widget to sell flights. Then I integrated a fully fledged flight search tool. Niched on the Australian market. Then I added hotels.

Revenue fell off a Grand Canyon-like cliff when covid struck, obviously, as nobody was flying, but has improved markedly this year.

Right? He's one of my favorite niche internet personalities.
AFAIK they use it internally, there are articles on lwn.net how, the use cases is for root filesystems and containers. I'm not sure I understand what you mean by the community sentiment, there are examples of code they'd developed internally first and sent it upstream, but in all cases I remember there were no problems. What can happen in the community is e.g. how the patches are organized or if the changelogs are complete. It's of course easier to develop something internally, if it touches other subsystems or if there's enough coverage just for the new code the test/fix/deploy cycle is much flexible. Once it's supposed to go through mailinlists or convincing other maintainers to accept changes it takes longer and must stick to the development cycle. This benefits both sides in the long run.
Seems a bit ignorant of politics. For instance he planned to travel to Dubai which would obviously extradite him. Silver spoon son of Stanford profs probably thought his donations made him invulnerable. Thankfully it’s embarrassing enough to the right people that he is wrong.
"Model detects people and can be fooled" is a poor way to understand ML in the first place. It's actually "model detects people with an accepted false positive and false negative rate". Different amounts of necessary accuracy lead to completely different model architectures, so of course it's easier to fool one that's been made easier to be fooled.
I'd argue spacex and tesla have terrrible terrible design teams.

Their stuff is pretty, sure.

However, that is only half of good industrial design. Their products frequently have severe issues with usability, manufacturability, etc.
