Even if it's VC backed, there's little reason for the VCs to prevent them doing a non-takeover tender offer in order to allow employees to cash out some (often capped) portion of their vested options and let in a new private shareholder.

And as someone who went through an acquisition exit in a just-shy-of-unicorn startup by a very big dog, yes, everyone's/VC's aversion to IPOs is definitely making it easier for said big dog companies to acquire people who in the past would have been shoe-ins for excellent IPOs.
>Most PDF readers support these and can verify the signatures using a PKI system similar as is used with HTTPS. Adobe Reader is a popular choice.

One subtle problem in this setup is the trust list. Abode effectively has their own trust bit sovereign rights, while EU has it's own trust list (which doesn't always match with a list of qualified providers as per EU-conforming states). Then US federal government has it's own trust list.

So it's the usual PKI problem.
I've said it before, and I'll say it again: Waymo's approach to self driving is a fool's errand. The only reason it works is that they have mapped out cities with straightforward roads and sunny weather to millimeter precision, and have hardcoded vehicles to operate in those conditions.

Compare this to Tesla's AI-first approach, aggregating training data from millions of drivers across the US. There's no overhead to introducing Autopilot in a new city it's never been in before--it just "works," with no expensive 3D mapping required, by extrapolating cheaply acquired vision data from other cities.

Elon really got this right from the beginning, but Waymo's aggressive PR and marketing have pitted public opinion against Tesla, as is very clearly evident even in these HN comments.
> In reality they're capitalists who saw a way to make money off of a proof of concept, and (ridiculously) thought they could shame the target into not taking obvious actions to squash them.

The "target" here is also literally the largest company in the world, whose executives have been discussing since 2013 about how to lock families into an iPhone monopoly that costs thousands of dollars a year by restricting iMessage [1].

There are no white knights here (it's all a money game), but Beeper's stance isn't as one-sided and ridiculous as you're making it out to be.

Replying here, but with conflicting thoughts reading this whole comment chain..

I really liked immersive VR I experienced in research lab settings like CAVE systems, over 20 years ago. I'm probably among the people most tolerant to artifacts like frame rate jitter and lag, and most easily able to still get an immersive pop out of it. But I'm not an early adopter. I don't see the value or place for this single-purpose equipment in my life, nor my budget.

When mobile phones were just phones, I saw them getting smaller and lighter. I even fantasized about them shrinking until it was just the ear bud. I was willing to hand-wave some sci-fi UX without a display nor buttons. But, I didn't (and still don't, really) appreciate how people would care to get wireless ear buds that are still slaved to a larger device. I'd still be satisfied with wired ear phones if they were available.

I also didn't imagine today's smartphone ecosystem, even though I saw all the PDAs and other pocket computing platforms and their general purpose potential. I didn't predict the social/marketing angle that was going to make any of this seem worthwhile to average consumers. Now, I benefit from these economies of scale making the tech affordable, but I barely need it. I still prefer going to a laptop or desktop for any "real" tasks. Ironically, a smartphone ir tablet makes me feel frustrated and "mute" without a keyboard.

I understood the idea of convergence and the general purpose device. I understood the mobile/always on value and was on the early side of wire-cutting to have only a mobile phone. But, I was surprised at how rapidly the smartphone ate up digital camera and personal video camera markets. I am still surprised at how much smartphones are eating into spaces like regular laptops and PCs. And now the entire concept of a phone seems to be disappearing, with traditional voice calls being less relevant as time goes on.

So I am a fence-sitter on some kind of N-dimensional fence. I admit that a lot of tech development might occur and I probably can't guess which ones get popular. Maybe there is some VR/AR angle that will finally catch on.

But on the more general topic, I also think that all these developments above had many other passionate developers and ventures working on slightly different angles that failed in the market. As a third-party observer of decades of tech, I do also think it's a lot of luck. It is survivorship bias to fixate on how NVIDIA or Apple or anybody had some perfect strategy to ride these big waves.
Ask HN: Can an human brain be used to geolocalization?
Now, the question is silly at a first glance. Perhaps because I am too ignorant of every thing in life.

I was watching this video[1] in which they depict using an human head as an Antenna.

The video lead me to question myself: How can we stretch this idea and find out new things related to ourselves?

Is it possible for our thoughts to travel to a receiver device? Like a WIFI Modem to a Cell Phone.

If these sort of questions sounds silly for you, I was just trying to exercise the Mathematical Thinking.

Also, I know few to nothing about the field of Electricity of Magnetism. But I will separate this question into another thread in this same forum.

Whenever I read posts like this I know, despite all the caveats at the start of the article, a large number of people will take away "we shouldn't have any foreign keys because they impact performance".

I suggest that anyone thinking that has a look at a database where there are no foreign keys.
A slight change in wording clarifies the case for me. Don't be attached to a/the solution.
And megacorps surely haven't taken extreme measures to avoid those taxes, also lobbying the crap out of officials who avoid enforcing them in the first place to not lose cool points in ""the global tech race"". Weirdly the good example here is Russia and China where the state did not refrain from extreme measures to show the market whales their place.

You literally cannot install another default messaging app on iOS with SMS integration. There are no OEM partners to speak of on iOS. If iOS reaches 90%+ market share, why shouldn't it be treated the same as Microsoft?
Tracking animals would seem to be a different set of requirements than, say, turn-by-turn car navigation.

I'd imagine that for a lot of research, longer lifetime would win over real-time ish data, and possible you don't care so much about precision and granularity either. You probably want to upload semi often or risk losing the whole thing, but otherwise minimize batter use.
Most traffic is not caused by sheer volume - this is well studied. It is often caused by inability to maneuver, merge, etc. As a result, your i-5 traffic would likely be much much better if everyone left 10 car lengths.

You do not have to raise the average speed of travel very much to make up the theoretical loss due to increased spacing

It's not about the button color, other than the fact that a green bubble means your group message is degraded and a bunch of expected functionality stops existing. It's hard not to feel some annoyance if someone is added to a group and that causes the experience to be degraded for everyone else.

I use Whatsapp for all my European friends, but getting Americans to adopt a different messaging platform is as unlikely as getting the Dutch to start using iMessage... So we're left with this situation, and it will continue until Apple/Google adopt RCS and cross-platform messaging becomes as seamless an experience as iMessage.

> a very small performance gain for strongly degraded data integrity.

It's not very small. Doing a lookup on every write can be hugely detrimental to performance especially with large numbers of writes.

> If the indexes are too much to ask you're basically saying that the referred to foreign records are never looked up (they have no key index!)

That does not follow. The lookup for foreign records is not free so avoiding doing it when you don't need to will gain faster performance vs doing it all the time. Indexes make lookups faster, they don't make them free.

Further, you have to consider the impact of locks on such a system. Writes to a table that references another will lock the contents of the second table while the write is in flight. So if I wanted to update the foreign record in any way, that task now gets blocked until data integrity check finishes.

In MSSQL, that lock is held until the end of the transaction.
A home gas stove in the US will probably make around 10k BTUs. Some have burners designed for high heat cooking that might go over 20k BTUs. Your average wok burner used for stir frying in a restaurant is going to be over 100k BTUs, possibly 200k. To be clear, you can do a tasty stir fry over lower heat; but realize that the commercial wok burners are specialized equipment, and any home gas stove will be underpowered by comparison.

I'm intentionally being reductive, but I have worked on several furnaces and gas furnaces are an order of magnitude simpler than their respective heat pump.

With Apple there's no such thing as “my device”.
This anecdote is not very surprising to me. Foreign keys are on a scale of DB constraints. I opt to add a maximum of constraints where I can. Adding a date that should be in the future - I'm adding a constraint! Did you mess up your time zone conversions & are trying to add a date in the past - the constraint catches it. At some point the constraints are strong enough where with high confidence the following statement can be said: "if the data exists in the database at all, it is correct & complete." This is the "database as fortress" principle, that only correct data should ever be allowed into the database to begin with.
I'm getting >50 tokens/second with an RTX 2070 Super 8GB on Mistral 7B with llamafile. More than adequate performance.
I agree that most people bet that rates would not rise fast.

But it’s a classic case of wishful thinking to not consider that and instead act like the highly unusual period of rock bottom rates was a permanent fixture.

Rates were going to rise, it was always a question of when and how fast.
> He is being met with treatment instead of punishment.

Treatment? From the article:

> He will remain at a secure hospital for life unless doctors deem him no longer a danger.

That sounds like punishment. For indefinitely long. Without even a trial.

If this were about treatment, we'd have details about how he'll be treated and for how long and the chances of success. Instead, we hear only about his punishment and vague scare-mongering about why it's necessary.
At that price resistive heating would be cheaper than nat gas.

Ah, maybe I was confusing the two effects. Good explanation, thanks. I guess holding the temperature better makes it feel like it heats more evenly, but only after it's well preheated.

Others may not necessarily agree, but at least anecdotally, a sizeable portion of drivers I see make all kinds of mistakes (law of averages dictates more of them are so called "neurotypical" than not no?).

"Acting Unexpectedly" can often mean following the actual laws and general guidelines for safe and/or defensive driving. I would hazard a guess that sometimes doing the intuitive thing is, in reality, unsafe and/or against the law. If the car does this in 99% of circumstances, and still gets rear-ended, who is really the problem here?
>My rule of thumb has been: enable them strictly in DEV and INT environments, disable in PROD

I mean I think the constraints should be on in all environments, but disabling them in prod but not dev seems utterly backwards? Protect your test data from getting corrupted but not your actual customer data?
This is functionally a Location Services feature, so the user should grant location permissions to use this.

This is wonderful news.

Supply chain security is essential to allow Rust to be used for critical infrastructure and replace legacy code.

Just as Rust has been a game changer in producing memory-safe and concurrecy-safe software, securing the Rust supply chain and ecosystem will also be a game changer for Rust adoption.
Of course it will.

But the economics still has to balance out. Zero and negative prices would have to be subsidized to maintain economic viability, which just means the actual price is hidden.
Getting to advanced level costs about 30k per year and ISO audit in case you wondered.

Not true.

There are plenty of things that we need that can run when electricity is cheap. Producing hydrogen or liquid fuel for long-range transport or long-term storage. Pulling carbon dioxide from the air either in direct capture or weathering. Desalinization for fresh water.

The big question is how to pay for those since they have capital costs and running them means that the power won't be free.

Well part of the "5% of a typical modern vi clone" capabilities is applying a regex over a range of lines, and judicious use of the "." command. Yes, that often replaces writing a script. But probably still not worth learning the editor for.
I agree - and I also appreciate the author's objectivity and focus on making the correct technical decision for the problem. Dogma is the bane of good architecture.

I completely agree with the idea that foreign keys aren't always recommended. For example, one of the reasons that MongoDB was so great at edge writes was because of the lack of referential integrity and the "document" as a row concept - denormalize the data into a document and store everything you need there.

That works great for high volume edge writes that you want to operationalize later, asynchronously. Sure, the data can be messy and may have errors - but many use cases tolerate this well.

The nice thing about modern postgres is that you get the best of both worlds, RDBMS stuff when you need it, and NoSQL stuff if you don't.

The author's point, which I think is an excellent one, is that just because it's in a database, it doesn't necessarily make sense to go full 4th normal form on everything.
So you have to write a replacement for the Google apps and get driver support. Sounds a hell of a lot easier than writing your entire OS from scratch.
Presumably there are open source apps you can install on top of AOSP that let you message and dial though?
They didn't work well at all back then. And they still work worse than LaTeX, although the deficiencies have become acceptable.
Can you clarify with examples/technical description how an open platform will be able to review & fix privacy/security issues like this more easily/faster? As far as I know this wouldn't be news on Android because such permissions are granted as a matter of course without review. Keep in mind that most people use the Google or Samsung stores which aren't open platforms for verifying permissions aren't misused.

For what it's worth spyware/malware consistently seems to target Android more than iOS [1]. To be fair Android has more units, but that's just one axis - iOS users should be more valuable to exploit because they're usually in a different socioeconomic bracket. Another data point is that Android developers get paid anywhere from $2k to $20k to add malware to their Google Play store app [2] - I can't find any articles similar for iOS so would be interesting to compare the marketplaces if anyone knows it for iOS.

If you do not particularly care about performance or have a great deal of headroom then database enforcement of referential integrity is great. Alternatively you could just write test cases to check for it and not pay the severe performance penalty.

The other major downside of database enforcement of referential integrity is the common need to drop and re-create foreign keys during database schema upgrades and data conversions.
As (very much) a layman I've hoped to see something like dynamic hardware acceleration. Eg for a game that has advanced hair simulation, or 3d sound simulation: reconfigure the fpga and offload the calculations. Maybe even more pedestrian things like fpga driven bullet tragectory physics might be implemented at the game engine level.

More optimistically something along the lines of hands-off offloading, where if the scheduler sees enough of the same type of calculation (e.g sparse matrix multiplication) it can reconfigure the fpga and offload.
> What it doesn't do is explain what is going to be the backup for long tail events where there's not enough sun or wind for days or weeks at a time.

Oh I have the answer to this one as someone who lived in Texas in February 2021 - you just don't have power; that happens sometimes.
Fair enough, agreed that social groups dominate the dynamic more-so (e.g. any country other than US). But being the default, pre-installed, and only app with SMS integration on iOS is an unfair position to compete from, especially when iOS is now slowly gaining dominant market position in the US.

The first to collapse will be nuclear reactors, because they cannot deal with such low prices. Only the cheaper energies can.

Even is you are half the year at a prize of 0, if the other half compensates you are fine. That's what drives eolic and solar, as they think "OK, in that scenario we would break even in 12 years instead of 6. Not bad either". Gas can adjust to produce only in the positive half of the year, and also "we would break even in 20 years instead of 10". Meanwhile, nuclear reactors and specially new nuclear projects, have to take in consideration than half of the time they will be producing at zero, and the other half barely covers the costs (mainly amortization). They are in a "at those prices we would never break even" scenario.

The key point is that the sources in the margin (i.e. with less profit margin) are the ones to collapse first, while the most efficient ones keep going on with less profits, but profits nonetheless.

The two scenarios that concern me long term are:

- What happens when all of the infrastructure gets built up around self driving cars and peoples first hand knowledge of how to drive diminishes. Once a near monopoly/duopoly is attained by a select few SDC vendors, it will become a utility. Then what fallback does society have if the likely enshittification happens. Do we just have to live with it?

- Its all fine when the companies able to do this are part of the most elite, technology first companies - but what happens when companies known to take short cuts (like the ones who can barely get bluetooth working for their audio infotainment system) start try to enter the market by focusing on lobbying the SDC oversight board.
