When even retailers have these prices, then those are the prices.

> I have bought around 4 3070s/3080s all for under 1000 at actual retail pricing.

How much time and effort did you spend to accomplish that?

I've signed up with multiple AIBs and Nvidia itself for months to get notified if anything I'm interested in gets in stock. Nvidia stopped selling directly in my region (Europe) a while ago, no AIB has notified me yet. Probably because I picked all the most affordable models, all of which are still more expensive than 3080 FE MSRP, while 3080 FE has not even an official retailer left in mainland Europe.

Sure, I could setup a whole range of alerts and spend all day hanging out in a bunch of discords to catch one of those super rare stock drops.

But tbh that's not the experience I'm looking for when I'm already willing to spend money: I don't want, and most people simply can't, having to organize the rest of their life around the possibility for a purchasing "opportunity" at any given moment.

"Xuantie-910: A Commercial Multi-Core 12-Stage Pipeline Out-of-Order 64-bit High Performance RISC-V Processor with Vector Extension"

From "VIII. NON-STANDARD INSTRUCTION SET EXTENSION"

Targeting at various industrial applications, XT-910 enables
a set of custom non-standard instructions, additional to the
standard RISC-V instructions. The non-standard instruction
extension can be categorized into two groups based on the
purposes - memory access enhancement, and basic arithmetic
operation enhancement.

A. Memory access enhancement

Memory access instructions usually account for a high
proportion in the total number of instructions, so enhancing
memory access instructions can directly benefit the overall
performance. By analyzing the mainstream applications running
on RISC-V, we observed that for the basic RISC-V instructions
there is still quite some room for improvement in memory
access related instructions.

First, we support register + register addressing mode, and
support indexed load and store instructions. This type of
instruction extension reduces the usage of the registers for
calculation and reduces the number of instructions for address
generation, thereby effectively accelerating the data access
of a loop body. Second, unsigned extension during address
generation is supported. Otherwise, the basic instruction set
does not support direct unsigned extension from 32-bit data
to 64-bit data, resulting in too many shift instructions.

I'm not certain if they break out the results by individual optimization, but in Fig. 20 in the paper it looks like all their tweaks add up to a 20% boost over the standard RISC-V ISA. Pretty huge.
I see this happening regurarily and i have to say that it heavily depends on the native speakers nationality.

Americans (at least if they don't speak some thick dialect) are easy to understand due to movies etc.

Brits are ok enough, but some dialects get tricky.

Irish and scottish usually are not understood by the absolute majority of participants. I pride myself in my ability to understand spoken english (relative to my peers here in germany at least) but even for me it is nearly impossible to understand an irishman talking over zoom etc. with some random headset.
No, it's purely about AIs and the control problem.

The problem boils down to "How can I control superior AIs through mere power of inferior humans?".

The assumption is that the superhuman nature means there is no way disable a superhuman AI because deactivation will not fulfill its cost function and therefore must be avoided at all costs, the superhuman AI will always outsmart humans and prevent deactivation, the same way a skilled soldier will always beat an untrained civilian in combat.

We have solved it for humans by accepting that the victor gets to lead humanity. Can we accept AI rule? Probably not.
Of course an implementation can do anything it likes, including defining the behavior. That's one of the infinitely many ways of handling it -- precisely because it's undefined behavior.

I'm not using "undefined behavior" as the English two-word phrase. I'm using the technical term as it's defined by the ISO C standard. "The construct has undefined behavior" and "this implementation defines the behavior of the construct" are not contradictory statements.

And "ignoring the situation completely" does not imply any particular behavior. You seemed to be suggesting that "ignoring the situation completely" would result in the loop iterating exactly 16 tyimes.
Depends on when. If we are talking about modern day JVM, than even the non-latency optimized default GC would have <10ms stop-the-world pauses for up to gigantic allocation rates, much less for the presumably minor one of a simple game. And then there are two latency optimized ones, Shenandoah and ZGC, with the latter having <1ms, meaning that your OS introduces more latency with thread switches.

So I think writing a game while profiling allocation rates and paying a bit of attention to not spam new everywhere, one should get decent performance without any framedrops. At most, optimize the hot loops with primitives, arrays.

> Something like 1<<32 is "bounded" UB, and can't result in anything happening to your program... it is permitted to result indeterminate values, it is permitted to trap, but that's basically it.

That is what implementation-defined behavior is for. Feel free to advocate for changing the standard accordingly.
Yes. But kids like to be exposed to the joy of engineering first. It's otherwise hard for them to justify the pain that's required to get to the joy of success.
The use of the word "parasite" seemed odd to me: at first blush they seem symbiotic: the ant gets the tapeworm; what it eats feeds the tapeworm too, and the ant gets a long and pampered existence. This, truly, is a symbiotic, not parasitic relationship.

However, it may be good for a single ant, but if you view the entire colony as an organism, what the tapeworm does is transform its host into a parasite upon the colony (this is mentioned in the article too). Thus, by transitivity, one might consider the tapeworm a parasite, not upon its host organism itself but upon the colony. Quite interesting.

BTW parasite was an actual job in Roman times, though a non-medical one.

My 2yo would like to sneeze on you and flip that anecdote on its head.
Does C-state tuning even do anything on EC2? My intuition says it probably doesn't pass through to the underlying hardware -- once the VM exits, it's up to the host OS what power state the CPU goes into.
I think that the authors ideas about what it means to know a language are implicit to the whole article but never directly discussed. There is knowing the meaning of a word and then there is knowing the contextual usage and conotative meanings. On their face, "expensive" and "costly" have the same meaning, but in many circumstances they aren't fully interchangeable.

To me, your "mother language" is simply the language that your mother, or other primary caregiver, spoke to you as a child. It is certainly plausible to have more than one in multilingual households.

A native speaker may not have spoken that to language with their parents, but they learned it natively from other speakers at a young enough age that their phonemes adjust.

In my opinion, native speakers tend to have a much deeper understanding of the meanings and connotations of the words/phrases they use but may indeed have smaller volcabularies than fluent, but non-native, speakers. The difference between "costly" and "expensive" is obvious to a native english speaker, but might not have been learned by a fluent speaker with a larger volcabulary.

If you listen to linguists, grammar is descriptive not prescriptive. Grammar is not a fundemental trait of language, but a model of language use that helps us think about how language is used.

I do think it is important to be aware of how we use language to enforce economic and cultural segregation. Language use is often used as a proxy for class and education and those who don't fit the "standard" are faced with discrimination.
Yes, my experience (not much) is that what makes YouTube or Google or any of those products really impressive is the speed.

YouTube or Google Search suggestion is good, and I think it could be replicable with that amount of data. What is insane is the speed. I can't think how they do it. I am doing something similar for the company I work on and it takes seconds (and the amount of data isn't that much), so I can't wrap my head around it.

The point is that doing only speed is not _that_ complicated, and doing some algorithms alone is not _that_ complicated. What is really hard is to do both.
I'm of two minds with regards to this: This is cool but unless you have no authentication, data to fetch remotely or on disk this is really just telling you what the ceiling is for everything you could possibly run.

As for this article, there are so many knobs that you tweaked to get this to run faster it's incredibly informative. Thank you for sharing.
The main driving force is that the rural residence are the remnants of the racist that moved to that area even pre-statehood. They don't like that their white power is fading and they want control.
yea, thats not really the story in idaho/oregon area. A lot of the issue there is that lots of the land is owned by the federal government, and the people who live near by and are in ranching/mining/logging don't want to follow the rules the fed gov puts on operations in BLM land. There is a bit of "some guy 4k miles away in washington isn't allowed to tell me I can't ride my dirt bike here" attitude.
If you decide to do an SPA, I'd recommend Next.js, because even if you use zero of the features and just put everything in a single index.jsx component, it does all the Webpack stuff for you. It also has some other useful stuff like easy support for rendering plain Markdown files into static files at build time, so you can use it as a more capable alternative to tools like Jekyll [1].

If param is unsigned, then "param + 16" cannot overflow; rather, the value wraps around in a language-defined manner. I've been assuming that param is of type int (and I stated that assumption).
I mean, not wrong, but Oregon was founded as an explicit white ethnostate. The state constitution language barring "negroes, mulattos and Chinamen" was not even removed until 2002.

> First, comparing capitalism to Auschwitz is obscene.

That phrase has been used before and after the holocaust to justify cruelty, but fair enough, it was in bad taste. Any thoughts on the obscenity of sending grandma to work the fields so she can afford her oatmeal?

> Second, nothing in nature is free. It isn't free for animals today: all of their energy is expended just staying alive.

Humans today work harder for their resources than hunter-gatherers did. Something is wrong with that.

> The death rate for children and mothers was horrifically high until fairly recently.

Again, it wasn't as high if you look further back.

> Entire diseases, once deadly or debilitating, have been cured.

One of society's great success, although again, these diseases only really started to spread once we decided to clump together year-round and slave away in the fields.

> It's sad that people instead babble about "slavery" and "sugjugation," things they know nothing about.

Good thing you're here to inform us all about how the people in the article, and forced labor around the world really need to shift their perspective and understand how good they've got it.
But is that being driven by people moving from rural Oregon? I am skeptical.
Except a lot on the left is driven by data.
I think it's worth considering whether or not rural vs urban is the best way to partition the argument. Cities tend to be very office/payroll dense, and rural areas more home dense. Some of the people who work in the city, and generate some of that revenue, may live in a rural area and consume services there.

As far as cost scaling, I kind of disagree. That calculation doesn't work well in the US, where a large portion of the people who work in the city commute. I come from a rural area and live in the bay area now, and I can say without a doubt I spend much more time on the road here. Same with emergency services, they were waaaayyyy better in my (very small and poor) hometown in terms of response times (or responding at all), and I can't see how that would cost more than running the same services here.
School systems are already run at a sub-county level, and depending on your politics you can pick which things being taught are abhorrent.

It seems self-evident that the anything for which the cost has gone up will take up a greater proportion of your budget than anything for which the cost has gone down, no matter what the things are.

I, for one, own a house and am not currently paying for anyone's college education, so the proportion of my budget going to food and clothing is more relevant to me. Should I say that I'm not interested in hearing people tell me how many fewer students I can send to college when I don't have any students to send?

CPI items were picked precisely because they apply to everyone. Raises in housing cost renters more, but increase my net worth as an owner, so it's left out of the CPI. Health care costs in the US are ridiculous, but they're also widely disparate depending on more factors than can be accounted for in a simple measurement like CPI.

Personal favorite feature:

> Any noun is a constant with the value 1 or -1, depending on whether it's nice or not. For example, ``flower'' has the value 1 because flowers are nice, but ``pig'' has the value -1 because pigs are dirty (which doesn't prevent most people from eating them). Neutral nouns, such as ``tree'', count as 1 as well.
They did, with a limit of something like max 10 outgoing mails/day, and a signaturen on all outgoing mail.
Just FYI if they starve to death there's no one to plant or harvest the food.

Also, if your argument is that the subsidies are unnecessary that would indicate that farming is profitable and they would in fact not starve to death. The point you're trying to make kinda collapsed on itself bud.
You can automate a lot of that if you used government identification and removed the nascent requirements that are currently in place.

Quite a few places do this, it's not an intrinsically hard process.
What I mean by that is that len is an obvious abbreviation for length that crops up in numerous languages. Not to mention code bases. It's simply not plausible you could forget what len means in Python after confirming one time that it is exactly what it looks like. (Unless you're a struggling non-native speaker of English forgetting the word length itself.)
Sounds like it's only a matter of time. We didn't have an incentive to create chips like the before, but just like with the specialised mining ASICs, we may see one soon.

Yeah, the problem is actually worse. Bitcoin is energy intensive. Chia is capital intensive. Producing capital costs energy so it effectively boils down to proof of work (burning energy to produce HDDs and SSDs). However, scaling energy is very easy, scaling HDD production is very difficult.

The only benefit is that storage can be repurposed very easily, thus booms and busts may cause temporary oversupply of storage.
especially that it is so easily manipulated by billionaires.

Ironically the billionaire in question is Elon Musk, who's company bought $1.5 billion of BTC as a treasury reserve asset. Tesla sold 10% of its BTC after it appreciated in price to make it appear to be profitable, even though Tesla made more money selling BTC than it did from selling cars.

The price corrected because said billionaire tweeted stale energy FUD because he wants to make his company--who's cars plug-in to a grid powered by fossil fuels and who's batteries are made from rare earth minerals from 3rd world countries--appear to care about the environment. And make Tesla look like an appropriate recipient of energy tax credits.

It didn't help that his tweet coincided with the news that China is banning cryptocurrency for like the 10th time and the fed having to admit that with the highly manipulated CPI being something like 4.6% that inflation might actually be a thing.

So you keep on thinking Elon or any other billionaire can manipulate the price of BTC at his or her whim.

Only true for Java runtimes at the time. With modern JVMs with generational GCs, it is detrimental even. Profile it, and only let allocation rate increase to an acceptable level that can be reclaimed easily. Or nowadays one can use a low latency GC as well.

I think simply telling web developers to "do more" is not the end of wisdom here.
What would be best is if browsers offered a "deaf mode" or "blind mode". I suppose the deaf mode would simply be turning the sound off but I'm probably missing something and that's my point here: It's hard to design for accessibility because I don't even have the proper means to test like a disabled end user would test the site. What would be best is if in a "blind mode" Chrome would make every text too blurry to read and I can only read things if used like a blind person would use it, possibly with a screen reader. Right now all we have are numbers telling us our accessibility score and I think even for that we need to use separate tooling.

Fantastic article. Disabling spectre mitigations on all my team's GCE instances is something I'm going to check out.

Regarding core pinning, the usual advice is to pin to the CPU socket physically closest to the NIC. Is there any point doing this on cloud instances? Your actual cores could be anywhere. So just isolate one and hope for the best?
Republican Reagan signed EMTALA which makes it so hospitals can’t refuse service in emergencies due to ability to pay. It stopped people from dying in the street. They did not fund this new mandate and so we currently pay for this through higher insurance premiums and county/municipal emergency service budgets. Universal healthcare would be a more efficient way to pay for an already existing benefit. When uninsured chronic conditions have reached the point you are literally in the ER / close to death, you suddenly get tons of subsidized healthcare. Subsidized in a grossly inefficient manner. Universal healthcare would lower costs through prevention.

I would have more respect for the right if they just admitted they are ok with people dying in the streets since they just ignore the economic effects of EMTALA.
Well, we already use botox.

Undergraduate shenanigans in the 1980s: The IBM PC was underclocked at 4.77MHz (as I recall) but rated at 8.00MHz, thus the "turbo" switch on many clones. Our little company had secret early-access IBM AT to develop software on as part of IBM's Scientific Software Suite. IBM paid to have a security system installed in our rented suite, and required that the machine be in my windowless office in a larger windowless back room. Was the AT also underclocked? The system frequency was controlled by a two-legged crystal soldered in, so I purchased a number of such from an electronics surplus outfit, soldered and unsoldered until I reached the maximum stable speed. It was quite a boost (I seem to recall that it was the video subsystem that was the ultimate bottleneck). When the AT eventually went public I made a few bucks hot-rodding them. Oh, and when IBM wanted their loaner back I did put the original crystal back in--only one coworker knew about this, and certainly not my bosses.
For your last point, the extent of UB driven changes to semantics is still not widely known in the programmer community. Programmers don't read the standard - they read K&R, and K&R is right now describing a different language. We've had 15 years of programmers repeatedly filing bug reports to be told that the expected, tested, relied on, behavior was ephemeral. Only very sophisticated projects figure out about UB.

Of course compilers have to make assumptions. The debate is (a) over what assumptions it is proper to make and (b) what are the permissible behaviors. The false dichotomy: either do without any optimizations at all or accept whatever UB gives you, is not a useful approach.
