California was giving property owners unlimited water access. Foreign investors were growing crops that needed tons if water in the desert and exporting them to feed livestock. This will probably be a good thing for actual good faith farmers and everyone else in the state.
> If the crypto is strong, and the key never exfiltrated, then this may be even better than an explicit overwrite, which on some media (like magnetic drives) may still leave trace hints of the old data that advanced techniques could recover.

The idea that magnetic drives left readable traces behind after an overwrite is a myth (especially of modern drives; if I recall the article I'm thinking of correctly the myth may have had a _slim_ chance of being true with old drives [like 100MB days]).
Comments like this serve to further justify my hoarder tendencies.
As a bonus, you help prevent the spread of that deadly virus that's ailing us all! (Please everyone, stay masked, no country is really safe yet)
Not sure where that article got the 300MW number, the GRE project is on track for the original size.
this does not apply to cryptoshredding or any modern storage media. even a single pass on magnetic media renders data unrecoverable.
Even if you didn’t have the public docs explaining this, you could make an educated guess because resetting the iOS device takes the same amount of time regardless of how much data you put on it and that time is on the order of 10s of seconds. iPhones don’t have erase speeds of 12gigabit/s - I don’t think there’s any storage technology that could do that. Also remember that Apple takes seriously the concern about the data leaking because the OS decided* to blacklist a bad block. Once a block has gone bad you probably shouldn’t rely on attempts to erase it working out.

* if I recall correctly iOS devices don’t use a traditional flash controller and Apple does that mapping themselves (it’s also largely why Apple devices have better flash performance than competitors)
They're probably just holding onto the building to sell it to someone else. The next buyer, in turn, is only buying it to sell it for even more. Tenants may even be considered a liability. They don't want to manage a property, they want to hold an asset as an investment.
What does that have to do with science or engineering?
When clicking that link in Chrome I get a "The site ahead contains harmful programs" warning page with a bright red background.

"Attackers on github.com might attempt to trick you into installing programs that harm your browsing experience (for example, by changing your homepage or showing extra ads on sites you visit)."

How strange... I don't get it for other github pages.
I don’t know if you could pass a law exactly like that, but it’s a good point that California could attack the problem from the other direction—-keep water law as is but squeeze the companies farming the desert using other parts of its regulatory toolkit.
If a person filing for unemployment benefits fails the facial recognition step a few times, they'll be directed to a video chat where they must show identification documents to what ID.me calls a "trusted referee," the majority of whom are employees (the rest are contractors).

This sounds like a service that the DMV or police or town hall could offer. Every damned public notary does the same when they notarize a document, they check the drivers license against the person. In other words - someone is grifting from the government.
I took a programming class at my high school in 1994. I was a sophomore and had been programming for a decade, including several internships. It was the first time the school had ever offered a computer class and on the first day the teacher started copying down code onto the whiteboard and as she did I and several other punks in the class started pointing out errors in her logic and syntax. At the end of the first day the school administration decided to make it a "study on your own" class. I learned a lot, mostly by heading out to the local bookstore and going through a few tomes.
The intellectual honesty one hits hard. A luxury indeed!
But dense urban cores tend to subsidize all of the infrastructure that makes suburban life possible. If the money weren't funneled in the wrong directions, there's no way it would make sense to be out of the urban core.

But why not? Are we obligated to support everything forever? If it’s hardly being used, and is starting to get in the way of safety and correctness improvements, why can’t we drop something old, arcane and unused?
Not sure if one needs to pay https://en.wikipedia.org/wiki/Deutsche_Welle for a 'puff piece' ;-)

Seems rather like reporting about what happens in https://en.wikipedia.org/wiki/Silicon_Saxony

Besides that we had some form of solar cell production here, only to outsource it to China decades ago. Much to the lamenting of the locals. Same for wind turbines. It's all embedded in the pork cycle/boom-bust scheme embedded in the maze of federal/state subsidies, policies and whatnot else.
I'd also look into LTO (lithium titanate oxide) if you're interested in long term cost per KWh, not because they are cheap by any means but because they (allegedly) last so long that you'd only be able to replace them maybe twice over your lifetime, it's a pretty new chemistry so unfortunately it's rather early days to verify whether any of the consumer offerings available today will actually perform for as long as the companies manufacturing them suggest (I've seen figures quoted everywhere between 5000 and 30000 cycles at 70% DoD), or whether you could even take advantage of those kinds of cycle counts before the cells just died from calendar ageing.

Back to NiFe though, you can certainly get decades of use comfortably out of NiFe cells, but it's worth taking into account that they require a lot of maintenance, routinely topping up each cell with deionized water (there are automated systems you can buy or build yourself to manage this though), and every few years the KOH electrolyte inside them will need replacing every few years, plus you will want to keep your cells adequately ventilated as they vent hydrogen periodically.

I would definitely NOT recommend lead-acid, sure the upfront cost is lower than anything else by quite a ways, but they won't last long at all, and as a result I'd be surprised if you weren't paying a lot more in the long run.

It's not the lipid nano particles that's the issue but basic high school biology that is missing.

People get confused because the media throws around high level concepts without building an appropriate mental model of how viruses, cells and vaccines actually function. This creates a fertile breeding ground for misconceptions.

For example there is a misconception that after people have been vaccinated they can shed SARS-CoV-2 as a result of being vaccinated. This seems to have started by the media saying that "people who are vaccinated can still pass on the virus" (a true statement).

So the media tries to counter this by saying "MYTH: people who have had the vaccine can't shed the virus" which just confuses the issue even more.

If the media was actually functional then it would educate people on basic biology and then they would be able to figure out on their own that A is false and B is true. Unfortunately this is not the media we have.
There isn't a huge problem with changing it, there are people who want to do exactly that and do something else instead. The prominent alternatives that I know of still do something to keep time tied to the mean solar day, though, and changing time standards can be a complicated process so it's likely to take a while.

Relationships are often about time you spend together with someone, and allowing you control over your time (first item) has a beneficial effect on relationship-building.

If you think about relationships being about giving and receiving, then what more valuable resource can you give someone than your time?
CA DMV is using ID.me and now forces you to share data with IM.me when you login or create a new account.

Seems like a disaster waiting to happen.

Worse, ID.me's privacy policy (https://www.id.me/privacy) states: The Service and Website offer eligible Users who create an account with an electronic identification resource (or “ID.me Account”) that allows eligible Users to verify their status as a member of an affinity group create accounts with websites that use the ID.me Account and access certain exclusive benefits, including without limitation, deals, discounts, cash back rebates and employment and educational opportunities, offered by participating retailers, service providers, employers or benefits administrators (collectively, the “ID.me Service”)

I always loved this name for my generation. I came across this term and this wiki article years ago and it's very fitting for people my age. Maybe those born from 78-84? I was born in 82 and I know for sure I'm the Oregon Trail generation because I played The Oregon Trail in grade school. And, I remember the Challenger blowing up when I was in kindergarten.

And the big differentiator for me is simply the lack of commonality that we have with the generations after us. Xennials really had the same basic childhood that someone had going all the way back to the 1920s. Anyone that grew up with electricity and at least the Model T that is.

The easiest way to differentiate between newer generations and all that came before if they ever remember a time before the internet at all. Because that and smartphones were the two big game changers for society that I witnessed.

The internet changed the economy enormously, and the smartphone revealed how stupid and manipulated people could really be.
That's a great portfolio, a very focused and intentional portfolio.

I'll be honest. I'm pretty astonished, solely from the things Unreal has put out recently.

I'm not entirely sure where Artstation fits in though, it seems to be a portfolio website for artists more than a marketplace. It has incredible potential though, if I owned the company I would turn it more into a social network, more chat/communication/group features rather than use it for its assets. I think its only serious competitor is DeviantArt and that website is well, how shall I say it, full of deviants.

I have never been in academia and this is the first time it clicked to me that citing a paper is not just an act of mentioning it as a networking artefact, and should be critical to the substance. Thanks for the explanation.
I don't think it's backwards. We started out with this big sweeping and simple statement that (seems to) holds true for physical reality, but it doesn't account for everything. The statement allows for two realities, one where there is one single global phase, and another where each point has its own local phase.

The first option might be true, no real way to measure it and that's sort of it, no explanation for all the other stuff going on. The second option is a little more complex, it requires an extra construct to make it work. And apparently when we do the math and work out this construct, it exactly maps to things we can measure in reality, that were not explained by the other simpler option.

So it's not backwards because it's simply the first full match in a depth first search through the possible realities that follow from this wave function theory.
No, GPS time will not stop, and that is the issue. What you describe is a regular leap second, but now for some reason GPS is broadcasting that it will have a leap second that doesn't actually do anything.
If you run tests through the loopback interface, you should be able to use any of the 127.0.0.0/8 addresses, instead of 127.0.0.1 (a.k.a ”localhost”). Each address has its independent port space, so you would avoid collisions/contention.
Dilute it with more sea water and send it to the Salton Sea. This would improve water quality in the Salton Sea while detaining the brine.
I will wear a mask for as long as I can without drawing any attention to myself. I've even thought about wearing a gator over my mask that has a print that fucks with facial recognition.

I figure there are still a lot of Greek Alphabet letters left for Corona that will give me at least a decade to continue to wear the mask without looking crazy.

I haven't encountered this before.

> In my experience, relying on recruiters to filter out candidates into a "high quality" pile isn't effective. That's where the resume bias tends to slip in.

I agree but I haven't seen anywhere (large companies) where this doesn't happen. There's always some intermediary filter before the resumes end up in the hands of technical staff.

I can't imagine why having recruiters involved prevents any of the other things you mention. ICs can design interview loops, help write job postings, work with recruiters to define and clarify what they are looking for.

Regarding your last paragraph, that sounds like the basic bar for most senior/staff engineer positions I've encountered. You're a force multiplier for others. That's the job.
I mentioned 3 wildly different orgs for that reason.
Sure, wealth can help with relationships, but how can you write an article about the highest forms of wealth and not even mention them? It betrays a particular view of the world and a particular set of values. And while it’s not out and said, I think this article is interested in achieving a satisfying life, for which I think relationships are more important than finance.
So most of my research is historical (military hardware [1]) and amateur. Building my own attempt has been on my TODO list for sometime. Assume I would use something like a CSAC (chip scale atomic clock) for local high accuracy, high stability timekeeping (and for my purposes, it's probably okay to cheat and fallback to GPS to get a PPS time update occasionally). It's my understanding that existing celestial navigation systems can discern stars even during daylight, but as I mentioned, I haven't tried it yet (although when you can detect celestial markers, accuracy can be as good as ~20 meters with a fix provided in sub 30 seconds based on state of the art).

To me, there's something profound about the idea of locating yourself in 3D space using light from stars light years away. GPS is great, but the universe is inherently providing beacons (not just stars, but also pulsars [2]) for positioning and guidance. That's very cool!

It would still be useful at night if paired with solar that produces more than the peek demand during the day.
That was my point.

I think GP was incorrect in the mechanism there.

> It’s not the same. I don’t have an option of who to build my echo chamber with.

Maybe not immediately, but Hacker News is absolutely an echo chamber. People who don't toe the line on certain popular opinions (e.g. social media bad) quickly learn not to comment because they know they'll get massively downvoted.

Hacker News upvotes and downvotes are supposed to be about whether or not the comment is a quality post that contributes to the discussion, but in practice they tend to function as "agree" and "disagree" buttons. Post something that is disagreeable on certain echo chamber topics and it's immediately met with downvotes, regardless of the quality of the content.

This effect is most obvious in posts about social media, big tech companies, drugs, and certain parts of the law. For example, I hesitate to even participate in posts about "LSD cures depression" stories any more because most of the commenters don't even read the studies and any comment that isn't 100% enthusiastic about psychedelics curing depression is met with a wave of downvotes.

Likewise, when I see a story about social media I can tell before clicking on the comments that it will be full of comments that start with "I don't use social media but..." and then a straw-man caricature of social media that doesn't match reality.

These comment sections are absolutely an echo chamber. People who disagree are barraged with downvotes and abusive comments, so they simply leave.

I actually had to change screen names on HN once already because I pointed out some flaws in a certain author's books, and one of that author's fans tracked me down and tried to argue with me on my personal e-mail address. Nothing like that has ever happened to me on any other social media site.
A time expressed in TAI that is in the future has no conversion to human-readable time. That is not a very useful piece of data for many, many use cases.
Cixin Liu (author of the three body problem) has a novel that plays with the concept of ball lighting. https://en.m.wikipedia.org/wiki/Ball_Lightning_(novel)
This is almost exactly my story. Didn’t have access to so much as a game console, let alone a computer or internet access, until late 1996. Grew up in a rural sleepy town, lots of slow offline time until my parents’ computer was given to me as a hand-me-down in 2000.

It’s a bit crazy being able to contrast the before and after. I can’t think of much that’s happened since that really compares… even smartphones were incremental by comparison.
Problem is that they don't distinguish themselves at a high enough rate to make up for the disparity. It is much harder for them to do so.
Thank you for making me laugh, that's a great mental image.
All jokes aside, in my experience it's nearly a FIFO, with obviously unqualified candidates being weeded out. If you have 3-400 people apply for a position, you maybe phone screen somewhere from 4-10 and by the time you're closer to 10 you've already conducted 3-4 onsites and put out at least one offer.
That's an opinion piece you linked there.

I'll reiterate that dollars are not a good way to measure the value to society of agricultural products, especially necessary vegetables like tomatoes. How do you measure the second- and third-order effects of the population having access to an affordable nutritious diet?
I read that as two different trips. The dumpster bit was during an earlier drive to Florida, presumably pre-vaccination. The hockey game was during a post-vaccination trip that saw them flying.
Is iron abundant enough for this to scale? Maybe this could kickstart the asteroid mining industry.
> Downvotes here literally slowly erase content that the community doesn’t like;

Most of the time downvotes are used to erase abusive content, but it's shocking how quickly some of the well-formed opinions in the content sections go gray if they don't agree with the popular opinion on HN.

At this point, I almost don't bother replying to HN comments if I know they'll just be met with waves of lazy downvotes.

The invisible hand of HN creates an echo chamber by teaching us not to post "content that the community doesn't like", which is often just comments that disagree with popular sentiment.
"Just an engineering problem" is a massive oversimplification.

It's an engineering problem that requires financing. After that, you still need to figure out how to do it profitably at scale.

The vast majority of "the science is done" breakthroughs fail to be commercialized because they're too expensive or time-consuming to figure out how to scale, or the unit economics just don't work out.
1) Modern research suggests that recovering data which has been overwritten once on magnetic media is probably not feasible due to the high density of modern magnetic storage devices and the use of dynamically aligning heads (e.g. that follow track geometry as they read) instead of absolutely positioned heads (stepper motors) that allow for more error in alignment.

2) Nonetheless, there is an appreciable risk of data remaining on the device due to non-volatile caches, remapped disk areas, and other factors that are not always well understood or disclosed by the manufacturer. Manufacturers have also been found to be unreliable in their implementation of ATA security features (e.g. embedded secure erase). As a result, with few exceptions it is U. S. government policy to permanently destroy all storage devices rather than trusting any kind of secure erasure. The typical NSA-approved method is either to degauss (surprisingly tricky to do right) and then crush, or reduce to 2mm particles with a device resembling a large, terrifying blender.
This is way more common than you think.

The sun is only 1 point of reference. You would want at least 3 to know exactly where you are. I suppose a built in compass would be a 2nd.

With two points that should narrow down the position to two possible locations (with rather large uncertainty).

Edit: thinking about it further knowing north would reduce it down to 1 point. You also need to know where you are in the world to know which way magnetic north is pointing. It would be 1 very fuzzy spot.
Fractal compression was never very good, so much so, that now, 30+ years after it's invention, is is not used anywhere. it was surpassed in nearly every way as soon as it was announced.

Ask HN: Why are most alternate browsers based on Chromium instead of Firefox?
Almost every 'alternate' browser in the market (Vivaldi, Brave, UG Chromium, Edge, Opera,...) is based on a fork of Chromium. Compare that with Firefox and I can only find few examples like Librewolf and the likes. Why are devs so eager to fork Chromium but not Firefox?
> But at least Macs have a built-in 7-pass erase option to comply with DOD standards

I recently learned that the "zero out data" options are not available in Disk Utility for SSDs. This probably fine if you were using full disk encryption, especially on modern T2-chip Macs that always encrypt the built-in storage even if you haven't enabled FileVault, but it was a little concerning when I was getting rid of an old failing Mac that had an aftermarket SSD installed without encryption enabled.
GPS time needs many leap seconds, as satellites experience a slower passage of time due to relativity.
