The way to detect an obvious cheater is when somebody rated like 300-400+ rating points below you, a matchup which generally only occurs in tournaments or the like (normally you wouldn't be paired down to such a large extent), plays incredibly well and beats you. And then you do computer analysis and you see they played near flawlessly. You look at the move timing and make really complicated and deep moves instantly. Then you look at their game history and see they played their last few games nearly perfectly. Then you report them and your rating points are refunded a few minutes later.

Lower rated non-chess players, the kind that are most likely to cheat, can't just pretend to be higher rated people because they don't know what moves are suspicious and which ones aren't. And if you think they'll just cheat for the first few moves and then turn the computer off... it really just doesn't work as well. If they actually have no idea what they are doing they'll still lose, and it's super suspicious anyways based on move timing and computer analysis.

And to my original point, if I were an 1800 player and wanted to sneakily cheat to be a 2000 player, I probably could pull it off, because that is close enough to my skill level that I could pretend. Maybe by using an opening book to make sure I'm getting great positions out of the opening. Maybe by only turning the computer on during certain key positions. But again, if I did this consistently, I'd get a 2000 rating and now I'm going to be matched up against 2000 rated players, and from their perspective I'm just a 2000 player. And what have I gained? I now have to cheat to even be competitive in a casual chess game, whereas if I just had my true rating I could just play normally which would be easier and more fun. This is why sneaky cheating just isn't very common, because the only people capable of doing it really have no incentive to do it. The only people who think cheating would be fun are the people who are easiest to detect.
Higher up someone posted an example of that and it seems like no:

Only one of the two shows, as expected it only shows if the ID of the quoted tweet is smaller than that of the tweet itself.

This also means that in general, you can't quote a non-existing future tweet hoping it'll be something cool in the future. Well you can but the preview won't work.

the tech population has always been blamed for housing or lack there of...after this flight, when homes and apartments become available, watch them stay empty even with reduced rent. why? because those who have always wanted more 'housing' could never afford it anyways.

if there are no jobs for 'techies', there wont be any jobs for the second tier in the service sector economy. they cant afford to live in the housing they wanted build. what they have always wanted was affordable cheap housing in the most expensive cities of the usa.

it was always the govt and their out of control budgets and unfunded pension liabilities. and feel good vote bank pacifying budget. blaming tech was a convinient distraction. because its easy to rouse the mob to go and lynch someone else instead of submitting to a forensic audit or a rip out transparent budget analysis.

This is the typical kind of response I have been receiving for eight years running now, whenever I say anything positive is said about Iran. Many people can't handle the obvious reality that every country has good and bad aspects - even Iran.

I could not care less what price Bitcoin ends up at, it will not change the garbage fundamentals, or my opinion of it, nor should it change yours. There's tons of different ways to make money investing, and I stick to traditional markets. Tesla has seen a 15X increase in value over the last year, Square 20X since 2016.

I suspect I may be insufferable when I see something that's just a giant waste of time, power, energy, effort and brain power, and I'm not mad about that.

I do wish you the best of luck making money, however you choose to do so!
There have been major investments to bring bitcoin mining back to the US, including partnerships to use natural gas and oil to power such mining: https://www.coindesk.com/us-becoming-bitcoin-mining-power-ag...

the only reason BTC has value is because it can be swapped for fiat currency. it will never be its own "thing".

Bitcoin is a non-sovereign, hard-capped supply, global, immutable, decentralized digital store of value. It’s an insurance policy against monetary and fiscal policy irresponsibility from central banks and governments globally.

This makes bitcoin it's own thing. It's early days, but satoshi's (1/100,000,000 of a bitcoin) are already the standard for a variety of transactions.

Bitcoin is already a store of value and we can transact in it; it's just a matter of time before it becomes a unit of account.

SF has plenty of those. Marriage and birth rates are low but immigrant populations are high. There are plenty of crowded multi-generational households in SF, it's just that they're largely immigrants rather than native-born San Franciscans starting families. (This is also born out in the racial COVID statistics, where infection rates are much higher for Hispanics and lower-income Asians than for whites and high-income Asians.)

The media reports the _known_ positive cases, i.e. those that were confirmed by tests and/or doctor diagnosis. There are also a vast majority of asymptomatic cases which are not generally tested or even contact-traced in the US.

We can't make claims about how much of the population at large is healthy because we don't actually know who is healthy and who is covid-positive/infectious/asymptomatic (and this is precisely why there are indiscriminate mask mandates in SF and elsewhere)
Specifically, it seems like it only shows if the ID of the quoted tweet is stricted lower than that of the tweet itself, which basically solves any sort of recursion and acyclic issue, as well as trying to quote non-existing future tweets.
Also, I have consciously avoided the term COVID negative. Exactly why I write “have not had a COVID positive test”.
I think what will make Apple Silicon a success is that they are not going to purposely slow down progress for the sake of sales and marketing. Apple is still an engineering-driven organization, despite their marketing genius. They’re not going to intro filler products here and there to squeeze the market.
Not bad! Yeah, wouldn't be surprised if those are part of the detection algorithm.

I would take longer to detect a cheater who is a bit more sly and only cheats on 5% of moves or less (the odds that someone would match a particular engine 99% of the time its pretty much zero), but over time, yeah, this would work.

I suppose another way to put its is that it's difficult to detect this sort of cheating from a single game, but not difficult to detect it in 100 games.

True, but the statistic is still useful with respect to comparisons to other locations in the country under the same reporting constraints.
Detroit is an interesting comparison, it is hard to imagine right now, but I won't count anything out completely. Obviously the factors there were very different. Detroit collapsed because consumers went elsewhere, not the labor.

Edit: clarification/wording
Nanoscopic barcodes could lead to new possibilities
This was a popular bit of news it seems.
1. x86 (and then AMD64) has had vast amounts of R&D money and talent thrown at it for decades, with the result that it has out-performed every competitor: SPARC, MIPS, Alpha, PA-RISC, Itanium, etc. As a consequence of this domination, it has a massive software, tooling, and expertise advantage.

But ... ARM, which through a series of coincidences, ended up being the right architecture at the right time for mobile devices, has had its own injection of talent and money, and has advanced rapidly in the last 15 years. The M1 is a long way from the ARM710 or StrongARM of the late 90's!

Similarly, computer circuitry has evolved. Early minicomputers used small circuit boards with just a few gates to assemble their CPUs. In the early 80's, bigger CPUs were built from multiple "bit slice" chips ganged together. The modern PC motherboard has been a thing since the era of the Apple ][, growing through 8, 16, 32 and now 64 CPUs with ever-increasing speed and power, but maintaining a model of a motherboard and expansion cards. SoCs have been a thing for embedded devices for some time now: the M1 is perhaps the first really high-profile "computer" to use this technique to integrate its major architectural components in one "chip" (package). I think it's inevitable that others will follow, given the obvious performance and power gains to be had.

AMD and Intel do this to some extend already. The AMD chips powering the new Platstation and Xbox consoles are SoCs, and Intel has sold embedded variants of its CPUs that are basically SoCs for some years now too.

x86 has a long future ahead of it, but for the first time since Alpha (?) it's seeing a major competitor. Unlike DEC though, ARM has a broad and deep ecosystem behind it, and (as the article points out) there are some advantages to the instruction set that x86-64 will perhaps struggle to overcome.

2. Microsoft already has the Surface. They've known for some time that Apple's integration of hardware and software is hard to beat, and that the iPhone represented a technology that could be applied to laptops and desktops any time Apple wanted to do so. So ... they've already made steps in the direction of competing, but they have a lot of business-model challenges to overcome in order to do so.

Honestly, I'd be much more interested in the futures of Dell, HP(E), Lenovo, etc, than Microsoft. This is a massive challenge for them.

3. No. The cloud vendors are already moving towards ARM for power reasons. The AWS Nitro board is begging to be integrated with a Gravitron -- I would be surprised if Amazon doesn't come up with a compute platform that's powered by a similarly integrated SoC in the very near future.

The M1 helps accelerate this process because all Open Source software will now have to treat AARCH64 as a first-class citizen (which, to be fair, the Raspberry Pi has already helped to do). Similarly, commercial software vendors now have another market that will need a native ARM version in 2 years (after Rosetta2 is phased out, like Rosetta was for PPC). So .. I don't think it's changed the cloud direction at all, but it could make the transition faster.
Most of these accusations of Dean are verifiable by people who understand San Francisco politics.

1. Wealth: Dean lives in a multimillion dollar mansion on Alamo Square that he bought for $1m in 1999. He has no loan on the property as covered in his candidate disclosures: https://public.netfile.com/pub/GetDocument.aspx?ref=7907215a...

And THC does not pay its attorneys nearly enough (just cracking 6 figures in 2020) for that kind of wealth: https://nonprofitlight.com/ca/san-francisco/tenderloin-housi...

I can find references for his Sonoma estate later, but his parents were wealthy New York merchants: https://www.nytimes.com/1962/02/12/archives/linda-rothchild-...

In general, when you have an entire family of social workers who attended elite East Coast private school for the first 22 years of their lives living mortgage-free in multimillion dollar homes, you should assume generational wealth: https://www.legacy.com/obituaries/nytimes/obituary.aspx?n=le....

It’s funny that this information doesn’t make it into the Wikipedia page.

2. Blocks housing: Prop I was opposed by the city economist because it was effectively a per-unit tax on new apartment development. Most apartments are developed and operated by separate entities, and it is common for developers to sell constructed developments to apartment operators. IIRC, the estimate was an over $30k/door tax on new apartment construction on top of the existing impact fees. Very few transactions over $10m are purely speculative or for cash flow (it’s too lucrative to just hold with Prop 13); most involve some development objective. The estimate was a 20% annual reduction in apartment construction annually (https://yimbyaction.org/endorsements/san-francisco/).

Prop K is a canard — it’s not even clear the city as met the quota allowed from the previous Article 34 authorization in the 90s. The primary reason there’s no public housing in San Francisco is funding, not voter authorization. It does look good to low-information outsiders, I admit.

Dean is famous for “blocking housing” in indirect ways. He advocates for inclusionary zoning at percentages where a project will never be financially viable without outside subsidy, like the Divisadero gas station project. In power, he blocks projects directly (https://socketsite.com/archives/2020/06/impact-of-modern-inf...) or through the addition of expensive, capricious delays (https://www.sfexaminer.com/news/supervisor-seeks-to-pause-hu...).

3. Never had a job: I think it’s common for this kind of pejorative to mean “only worked for employers who are not incentivized to perform” (i.e. public / non-profit sector), not literally “never earned wage income.” Certainly applies to Dean.

Coins are essentially worthless as well. Ok, they have a 'book value' of the (usually base) metal they're made from. But that's about it.

So what has 'true value' then? Gold? It's similar to Bitcoin, in that you have to deposit it and use an exchange.

It is a limitation in general in FAT filesystems all the way up to FAT32. Long filename support is a bolted on optional extension.

I'm working on an embedded project right now where long filenames aren't needed and flash space is limited, so everything is 8.3 all capital letters.
The wealthier might lose more wealth overall (if we exclude the options they have to diversify and protect) but that doesn't mean it won't be harder for the poor. A poor by definition doesn't own much. They probably have no house, no easy way to eat, no way to transport if the system collapse and the merchants aren't interested in the little fiat they have. All in all I'm having a hard time to defend the idea that it would be harder for the wealthier to go through a collapse of the currency.

As for bitcoin, well, you can audit the commits on github if you want. There's plenty of things added lately. Miners or other entities like nodes can decide to fork the protocol into another chain (already happened, the protocol is then developed differently in those chains). Rules are subject to a consensus. Also if a user is not happy with a change, he's free to stop using it or to exchange his bitcoins for something else. All in all there's no reasons for participants to refuse modifying and improving the protocol over time.
I haven’t read the linked AnandTech article yet, but is there a clear answer why Apple was able to defy common comp arch wisdom (M1 has wider decode which works fine for various applications/code)?

First I heard of Kindles having Linux installed on them, I'm too excited by hackable e-ink device.

I've never owned a Kindle, are they priced below their pure hardware cost? If so they suddenly become very tempting.

I don't know what I'm looking at but it looks like the current generation is around 50 Euros.

In most major cities on the East coast at least, this is definitely routine practice but they just hide it from you.
When Supercomputers and GPUs are pushing 1000GB/s with "high bandwidth memory", its utterly ridiculous to call a 70GB/s solution 'high bandwidth' (128-bits x 4266 MT/s).

There's an entire performance tier between normal desktops and supercomputers: the GDDR6 / GDDR6x tier of graphics RAM, pushing 512GB/s (Radeon 6xxx series) and 800GB/s (NVidia RTX 3080).

To call 128-bit x 4266MT/s "high bandwidth" is a complete misnomer, no matter how you look at it. Any quad-channel (Threadripper: ~100GB/s) or hex-channel (Xeon ~150GB/s) already crushes it, let alone truly high-bandwidth solutions. And nobody in their right mind calls Threadripper or Xeon "high bandwidth", we call them like they are: quad-channel or hex-channel.

Surely there were compilers, they just weren't as good (as optimizing) as Intel wished.
I don't really get what you are talking about. Everybody has been doing MMIO for a while now (and by for a while I mean multiple decades), and IO is usually not an issue in personal computers anyway; OOO, compute and the memory hierarchy is. We are not discussing about some mainframes...
And now there are 4x as many deaths due to drug overdoses (by fentanyl alone) than Covid! [1]

If you really care about public safety, you should pay attention to homelessness, drug addiction, and the problems in the streets! It's killing people 4x as fast as Covid, and yet nobody cares! This is exactly the problem that GP was talking about, and you come back with a smug "well our Covid rates are really low" comment.

You're ignoring the point by looking only at Covid. Look at the rest of the data. A city is more than its covid rate.

Imagine a phalanx of drones, one for each car in the procession, all arriving and detonating simultaneously. Not as incredible as we may imagine. If fact, pretty much the state of the art.
Unfortunately each faculty member produces about 30 PhD students in their career (one per year). The number of faculty positions has been close to flat since the 1970's. So one in 30 PhD's will get to be faculty member. She probably took the job because she wants/needs a job and the company likes to have the status of PhDs doing the work.

Wasn't that a peering agreement? IIRC, ISPs weren't throttling Netflix per se — Netflix was just paying them for direct access to their last-mile networks, rather than going through "the open internet".
