The updates are often fatal, though. These include things like the Opteron "Barcelona" TLB bug and the first-generation EPYC "Naples" frequency scaling bug. The fix for the former knocked 20% off the performance of that generation of parts, and the fix for the latter meant that you had to run at the base clock frequency at all times, getting neither turbo boosts nor power savings. If you apply all of the speculative execution workarounds to an older Intel part like Xeon E5 v3 you will lose something like a quarter of the performance you paid for originally.

A search engine of the future would need to coincide to the ux of the future. AR will be a thing so it’s conceivable to connect a query to something your looking at or your location. Augmented searches will largely be more and more ai driven. Expect a greater emphasis on authenticity. Novel methods will be introduced to authenticate a search and possibly be combined with cryptographic ledger like ability.
That's because many of us already have changed our minds. Many of us were big fans of Bitcoin ten years ago and really excited about the prospect of trustless digital cash. We thought it would work. But now that a decade has passed, we've changed our minds.

Yes. That. Exactly that. Compilers cannot assume that, because (in the general case) it is not true.
Well they did a lot for Japan and Germany after WW2.
You are right, power supply improvements are asymptotic. It's not just about total efficiency, but also about how the heat is generated and where you can put it. A lot of the newer developments don't do a lot for total efficiency but produce smaller supplies by more efficiency managing heating.

That said, most supplies for sale are based on old, fossilized designs created ~10 years ago, hovering at around 80%. If you spend more you can get the gold, titanium, etc. But then, even those tend to be below the maximum you can get, which is closer to 98% if you have information about your load. You can also design the system to have better efficiency at various loads. Typically half, but could be worth tracking newer CPU/mobo/GPU developments.

Sorry I wasn't clear. The DAN and other pulsed sealed tube neutron sources use a penning trap for their ion sources. But yeah, it was an incomplete and inaccurate wording.
Absolutely overkill to have a metal server at that cost to send emails. A cheap VPS (which always comes with its own IP) is fine in most cases.

From experience I can confirm the reputation build-up requirement though. And all that reputation can get ruined by a single blacklisting - even if you manage to get the server de-listed later the damage is done.
Well, Germany could build a gas pipeline through Belarus, too.

Ask HN: What are some things you learnt from a game that changed your life?
I find it fascinating how some games turn out to reflect much of my philosophy about life. For instance, I played Inside a while ago and was amazed by how much you can achieve by so little. The game was mostly about timing, and you'd be surprised how much of our life is just "hacking time" (I first heard this phrase in Mr. Robot.)

Catan (board game) taught me the power of being forward-looking but also being myopic depending on the type of your opponents. It also taught me that I don't belong to games (situations) where one party is being irrational and acts based on knee-jerk decisions. In Catan, I now try not to reveal my best card and get ahead early on in the game in order to avoid becoming an easy and default target for other players. I think these are really interesting life lessons I (re-)learnt from a game that wasn't even designed with that purpose in mind.

I'm looking for any and all games that can potentially teach me something, but are not "educational" games.

> A very basic usage: using Curve.fi to swap between tokenized USD (USDC) and tokenized EURO (EURS) with minimal slippage and fees, all permissionless, all freely accessible.

As a sibling comment noted, this is hypothetical usage, and a future 'promise,' not actual usable by or providing value to the average person.

I went to curve.fi, and from a first glance, anyone not first-world, techie, and extremely familiar with crypto would be completely bewildered by this.

"Select a wallet to connect to this dapp" — what is a wallet and what is a dapp?

"Swap using all Curve pools" — what's a Curve pool?

"Trade routed through alusd" — what does this even mean?

"Base APY" — what? I thought I was exchanging currency, not opening a bank account?

"veCRV holder/LP ratio (based on fees): 28.74" — This is where even first-world, college-educated people close the website in confusion.

I meant APIs, not UI or tooltips. And while Wikidata entities and properties could be accessed using MediaWiki API, arguably, there are, at least, two issues with this: 1) you have to know exact names of all the relevant metadata, which is quite overwhelming* (and the SPARQL query editor's autocomplete feature does not seem to help with this, except for top-level attributes); 2) entity disambiguation - yes, it can be implemented programmatically, however, it has to rely on knowing exact names (values), which brings us back to the point #1.

*) Here is an example of the number of attributes for a single entity: https://www.wikidata.org/w/api.php?action=wbgetentities&ids=....
I had some contact with PSU designers at a name brand server company and learned some things:

1. Electrolytic capacitors: Only Japanese brands can be trusted (this sounds racist or something, but it's an actual requirement). They all should be de-rated for reliability (have 2x the voltage rating). Only exception is the main bulk filter capacitors, where your only reasonable choice is 450V, but these should be 105C. Tantalum capacitors: not allowed.

2. Main switch MOSFETs: only Infineon can be trusted. Single active clamp / single switch topology is a no-no due to bad experience. (I think the one in the article uses a diode clamp, so should be OK).

3. Standby supply needs its own fuse. The problem is that the main fuse is too big for the standby supply. If there is a standby supply fault, you will fill the machine room with smoke and your brand will be mentioned in the news when machine room is shut down. This destroys shareholder value.

The current limit for any exposed 12V rail is only 20A or something line that (240VA UL limit), so you must not have exposed 12V when the server cover is open.

There was basically a 100 page requirements document all along these lines.
Money transfer is impossible to stop as long as P2P exchange exists. My country banned crypto a few years back. I just bought in-person. Nigerian central bank banned crypto recently. Nigerians just exchanged it over Whatsapp

This is a deep cut I expect will go over the heads of a lot of non-EU residents (though "enterprise architecture" might still clue them in).

I was shocked to find RDF-era ontology "research" - already rightly a joke in my US-based undergraduate AI courses in 2003 - going on en masse when I moved to the EU in 2011. I've gotten four job applications so far this year from people with MSc in whatever ontology trash their local university was doing.
You idea about a misinterpretation of Gorbachev's words "violation of the spirit" is contradicted by the rest of that sentence, binding the spirit to the words of the Treaty of 1990.

The very promise to Gorbachev that NATO would not expand eastward is, as he says, legally enshrined in that treaty: "Foreign armed forces and nuclear weapons or their carriers will not be stationed", though only for the east "part of Germany". At that time it would have been unthinkable to discuss any further expansion of NATO.

To blatantly deny this fact is "modern-day NATO propaganda". But you are welcome to claim, that "no discussion, no promises, no agreement" about this was ever written in treaties - if you every time remember to add "except for the part about eastern Germany, where that promise is very well documented".

But the smart contact cannot interact with real world. It's the party on the other side that ultimately gets the funds and acts on your behalf. That party can just take the money and go away.

Unless we're talking about purely on-chain strategies. But in that case why wouldn't you copy their public investment contract and execute it yourself?

> Can you say the same about your investment bank?

My investment bank has a tonne of regulation on it. If they go under and I can't claim insurance on it, then we have bigger issues where "money" may not be an answer anymore.

The workers also would be liable to local laws if they tried to literally walk away with money. (Sure, we have various enforcement issues, but the alternative of none-of-that doesn't sound great)
> Mutating the gen of one species, often with poor results, is clearly different than introducing the gen of a different species into other that can be even classified in a different kingdom.

Genes aren’t inherently kingdom specific, and mutagenesis can produce genes that don’t even exist in nature; moreover, it produces changes all over the genome; when you then select for a desired trait, you still have unrelated changes all over, whereas there is a whole lot more control and knowledge of what you have with transgenics.

Yeah, they are different techniques, but it is insane that mutagenesis (especially in its modern forms) is not treated as even a moderate concern by the same people who hold up transgenics as an existential threat.
> I wish this had caught on.

It did. It's still available in Windows 10.

And it's what everyone used throughout the eighties and most of the nineties, until Microsoft copied the silly Cmd-X/C/V (only with Ctrl in stead of Cmd) from Apple for Windows 95 or thereabouts.
This argument lends itself to constantly shifting goal posts. The moment Apple (the food safety authority) closes down a store for a breach of standards it has enforced, people will simply say that Apple is engaging in censorship, or not being open enough with its platform, or engaging in anti competitive behaviour.

The issue is compounded by imagining that the food safety board ran its own restaurant. It then closes down the cafe next door for unhygenic practices. Looks pretty bad right? That's the situation Apple will be in every time it has to make a call on something like this.
Visitation numbers from the article:

"Despite the challenges and restrictions of the COVID pandemic, 129,218 people traveled to Crater of Diamonds in 2020 for what was a record-breaking year, with more than 80 carats of diamonds unearthed"

At $10 a visit the entrance fees add up to a lot more than the value of diamonds found. Kind of like a lottery, but more interactive.

Really tiny Torx screws are easy to strip the head on. I've done it more than once, to my considerable regret.

Pentalobes are harder to strip, because a pentagon is less like a circle than a hexagon is.

Are they the Platonic ideal of a screw head for the exact size used in iPhones? No idea, I'm not a mechanical engineer. Just a klutz who has stripped a few tiny Torx screws with my big ol' meat hands.
I agree it should matter less when looking for experienced candidates. That was their company culture. There was a time in the US when a lack of degree didn't matter if you had competence and experience. But that ship has sailed and most of the tech industry now prefers to hire people with a degree.

(Perhaps cultural context also comes into play here - A British banker had come to India for some conference. After learning about how the banking industry in India is, he asks one of his fellow indian colleague on why indian banks asked for a college degree for a Clerical position, where as British banks in UK stipulated that high school diploma was enough for such positions. The indian guy replied, "When I can get a college graduate for that position, why would I hire someone with a lower qualification?".)

Quora answers claim the book referenced in the NYT article actually does contain info on the trick in question.

It sounds like your average magician stuff, influence, misdirection, memorization, skill and patter. The quora answer claims there are about six memorized decks, and that there are generally attempts to ‘force’ the right number after the the card has been selected. If the wrong number is chosen, there are ways to to mitigate the issue going all the way to manipulating the deck.

Getting angry was part of the trick, for sure.

> Tulsi Gabbard ran in 2019 in part on rapprochement with the NRA, so that's not a great example. Trump ran against Cruz in 2016 on universal health care, and was attacked relentlessly by the GOP field for it. See what I mean?

I really don’t. In the House Kirsten Gillibrand had a 100% rating from the NRA. Gabbard merely said she’d talk to the NRA President, analogizing him to the Syrian dictator! She didn’t sign the assault weapons ban in 2018, which was a smart move if she was running for President.

Being a left wing pro-gun Democrat was a thing like five minutes ago. Sanders, Dean, etc. Has the party moved that far left?

It’s not that I’m not sold, it’s that I don’t even understand the argument.
Assuming bar isn't inlined (eg separate compilation unit, as you mentioned), the null check in MACRO is not unnecessary, because bar can be called from places other than foo, and those places might pass null pointer.

This is one of several situations where it might be useful for the compiler to excercise it's perogative to implement operations without regard for undefined behaviour to rewrite `use(*p);` as `if(!p) abort(); use(*p);`, which would make the null check in MACRO unnecessary, but unless it does so, the check is not unnecessary, just insufficient.
You're right. When there's massive non-compliance with the law, there's something wrong with the law.

At a previous job, all API errors were emailed to internal email lists.

The dev monitoring the API health kept track of system health by looking at the number of unread messages in his inbox. If the number of unread messages went up by < 100,000 in a day, the API was doing fine. If there were a couple million new messages, it means we were having problems.

So... I can definitely see how this is plausible, if not uh, "best practice".

Sadly, this says more about how broken GMail now is than anything else.

Real Soon Now(TM), the tech community needs to start a serious campaign to shame and isolate email providers that do not reliably deliver legitimate emails, regardless of how high profile they are. It probably needs meaningful government/regulator backing to get anywhere. The odd false positive on spam/malware filtering is understandable, it's not a perfect science, but the reality today is that a lot of these services simply don't work properly and the unreliability is probably causing some degree of damage to huge numbers of people and businesses. Email is far too important for far too many things to let the reliability continue to degrade according to the arbitrary whims of a few large mail services and to permit oligopoly effects to lock new or small-time providers out of the system almost entirely.
And some people find it fun.

It essentially means that the Code is the product. Everything is visible and public. Every smart contract can be publicly viewed and verified. If the code isn't up to scratch, you can review it. If it has an exploit, you can detect it. Whatever it is doing, is transparent.

> And if this were true, then why do so many apps still use the Play Store on Android? Why haven't they all switched exclusively to third-party stores?

Play Store doesn't have an app review process, and yes, permissioning is a major problem there, the "flashlight app that wants network access and your contacts list" was a very real thing (until Android finally implemented a flashlight app) and continues to be a thing for other types of applications.

https://www.extremetech.com/mobile/298363-why-do-android-fla...

That's the thing app store review prevents on iOS, and the changes you're suggesting fundamentally undermine that process. When facebook removes themselves from the app store and creates their own so they can demand full permissions, the choice will become "give the permissions or stop using facebook" and that's a degradation of the iOS user experience, all for a nebulous argument that the app store cut is too much.
