Reminds me of a story in when I was in university in around 2005. In our usenet group some people found a sale of used fw900s (definitely for less than 500€ each). They then organized a group buy, which had around 20 interested people.

Then they wondered how they would actually get all of those transferred across half the country. I think in the end they rented a truck or trailer to pick them up. It was definitely a bigger feat than getting a LCD shipped from your favorite online store.
Good point : ).
Invention of Stereo Sound: Alan Blumlein – 'Walking and Talking'
That’s a stupid principle. If you don’t have your interface well-defined enough that switching out the hashing implementation is difficult, your code is too tightly coupled.

A test handing a hash collision is not a test of the hashing algorithm so you should be able to switch out the algorithm to something super predictable. This isn’t a discussion about mocking frameworks - you should be able to do with by just plugging in a different hash implementation when you construct the test.
I doubt I'll ever ride a bike to work in the winter. I say this because there's a backwoods road on my commute which I cannot avoid and which gets skinnier and skinnier as the storms add up. It reaches a point where two lanes become something closer to one and a half, and where I suspect a difference in vehicle height is occasionally the only thing preventing side-view mirrors from clipping. Drivers remain unfazed, or at the very least they do not slow down.

The president of Exelon stated that CO2 taxes would have to reach $300-400/ton for new nuclear to compete with NGCC in the US. Renewables would likely be used instead. For nuclear to replace intermittent, gap-filling NG generators would require far higher taxes.

CO2 taxes could keep existing reactors operating, though.

Hi pk78

- I use the email to announce my upcoming product to potential users. It's also a free product and also a product for tech founders so it seems fair to me. If I cannot communicate with my users, then it's hard to build something.

- 67 decks = 1210 slides. You are the 3rd person to point this out so maybe my English is wrong. For me, 1 deck is a whole presentation that includes many slides. Please correct me if I am wrong.
8 results total, with exactly one entry that’s remotely relevant (i.e. performance related, patch provided) — bpo-21955. You could have just linked that. And this happens to be a patch from a core dev. And it’s not comparable to submitting a performant implementation of a PSL module like csv. You have chosen a pretty convincing example, I don’t know what I’m supposed to be convinced of though.

StarCraft 1 Pathfinding: A Technical Analysis (2017)
Prices determine the allocation of resources in society. Higher prices of food in New York allow a dense city of 9 million to channel enough food from the economy to feed the populace. The more accurate the prices, the less waste (in terms of both the commodity and time).

While it may seem like any improvements to price-time reactivity would be negligible compared to the 300mm investment, these things are simply too difficult to measure in a complex system like a global economy where any change can result in a butterfly effect. Over many years, more reactive prices could prevent arbitrageurs (who perform a critical service) from making less efficient trades. In fact, the firm who commissioned the new line is likely doing arbitrage, which is one of the key services that allows us to have a globalized economy with relatively stable prices.
Prices are information about the relationship between supply and demand, they allow people to make accurate judgments about resource allocation. This information is time sensitive so any decrease in latency increases the accuracy of the information.
I didn't mean it doesn't.

My point was that trade, in a wide sense, creates wealth. No one would cross the sea or the desert if there wasn't a prize, so I take for granted that there is an inbalance.

"Bottleneck" seems to suggest that commerce is like a natural process. It isn't. There are trade cultures like Phoenicians or Renaissance Venice, but often the powerful don't like commerce. Commerce implies some values that subvert authoritarian regimes, maybe just because different ways of understanding life make contact.

So when I hear bottleneck, I think of trade restrictions, not flow. You mean bottleneck as a funnel where the flow is more intense and thus more susceptible to capture wealth. It makes sense, but it's somehow a twisted metaphor, because it's the inbalance (gravity, or demand + the cheaper production elsewhere) that creates the flow, the bottleneck just make it easier to exploit. But a cascade can be wide or narrow, tall or short. In any case, there's water falling...
It is terrible that people equate bike lanes to cycling. Bike lanes are built to kick cyclists off the roads that motorist believe belong to them. It is very ironic that because of the pandemic so many defenders of bike lanes are coming out like mushrooms. I find it ironic, because to me, the pandemic has shown precisely that there is no need at all for bike specific infrastructure. In Madrid, the city where I live, during the worst months of the pandemic, I would go out with my bike and there would be a ratio of like 20 bikes to 1 car. The cyclists that I saw used the traffic lanes as they needed. It was quite something. You would think that proponents of bike lanes would have to shut up. But no, now they say that bike lanes are the solution to the pandemic!
Isn't the liquidity only worthwhile at times of low liquidity? The ability to quickly exchange shares only matters at times when you want to exchange shares quickly. The only time when you care about exchanging shares quickly is if the price is changing quickly. Those are exactly the times when HFT is the riskiest, and the most likely to be shut off to avoid losses. (For example, shutting off HFT as a response to the 2010 flash crash[0].)

I get the argument, but it feels like the societal benefit is taken away whenever it is needed, and paid for only when it isn't needed.

The IBM 53-bit quantum compute result from a ton of hard drives + compute power was also intriguing (https://www.ibm.com/blogs/research/2019/10/on-quantum-suprem...).

128PiB of disk space needed for a 54-qubit computation on their system (hard drives). Fun to see where the supercomputers are still needed, but smaller qubits can be emulated on normal computers. 40 qubit calculations probably can be emulated on a 16TB team of hard drives in RAID0.
Presumably the phosphors in the PAL CRTs glowed for longer?
It is true that when you graduate from a prestigious university, society at large has a superficial notion of your competence/abilities at the outset, but in the long term, i think what you actually do as an individual defines you. There are tons of people who graduated from a great school xyz whose only real accomplishment is graduating from xyz. Do not let labels define what you can do with your life, once you buy into that game, you are mentally boomed for the rest of your life. Einstein certainly never said "oh i work at a patent office, which must mean i can't become a world class physicist", no one (or institution) owns creativity, knowledge, passion or drive, and those are the most important qualities that drive the world.
Michael Burry made his name by doing a deep dive on mortgage backed securities. He knew what he was talking about because he crunched the numbers before he attracted attention.

How that experience translates into macroeconomic forecasting, such as when he said farmland was the next big play, or now passive investing is bad, I don't know. Has he crunched the numbers, or is he using some theoretical framework to try to predict macroeconomic events? In any case his words attract a lot of attention now, even when he may be speaking outside his areas of expertise.

You're right. The more fine-tuned it becomes, the more you have to consider low-level protocols. This paper https://nvlpubs.nist.gov/nistpubs/jres/121/jres.121.023.pdf suggests with current systems, time uncertainty can be decreased to about 1-10 us from NIST.
I knew that this pandemic would lead to a revolution sooner or later. Nobody believed me.
Totally. And my apologies if I implied a lack of "will" was the issue - God knows I struggle enough with that.

I think that "the path forward" is a mix of things. Often we have opportunities we have not tested, and, part of the path forward is discovering how to change our habits, environments, or thought patterns.

One of which is reaching out for help.

And sometimes you are absolutely correct; there may be no path. But, people's life circumstances differ so much, and any kind of change like this requires effort, commitment over time, and continuing on past roadblocks, that I doubt "an answer" is the right approach for individual people.

Usually it's the walking of the path that's trickier than ascertaining the path itself. Usually there's at least a glimmer of what might be a path ... except for the darkness within ourselves.

Now, governments, institutions, yes - I do believe our institutions should provide more opportunities for people.

Likely a C programmer with little experience doing testing with fakes. Most C projects I’ve worked on are horrible at structuring the code in a way that makes it sane to do dependency injection or mocking.
Idk if that's right, if I didn't force my self to do anything I'd be sitting around watching TV, ordering food and smoking weed. I think most if not all lean naturally lazy.
Any reason the hash function and the collision handling can’t be separated and mocked for unit tests? What if you decide to increase the bits of hash values or change the hash algorithm?
You've got it backwards. We've built nuclear plants. We've encountered unknown difficulties and overcome them. Our cost estimates for nuclear power are historical estimates. We did built nuclear at scale before, and it did cost less.

By comparison, the cost estimates for building things like massive amounts of energy storage are cost projections. These costs represent what we think these projects will cost. But these projections, by definition, don't account for unforseen engineering challenges. Historical costs do.

Comparing the two is apples to oranges. Historical costs include the cost of engineering challenges, cost projections for new technologies do not.
I use writing as an indicator where I land on Bloom's taxonomy for a given topic. I also use it as a tool to increase my own comprehension; and—to put it bluntly—to call myself out on my own bullshit.

WHO warns against Covid-19 lockdowns due to economic damage
Actually POI search is already possible and works (according to our tests and effort) in some countries like in Germany ... but geocoding is another big topic besides routing (and map visualization) that you need for a good map application. And to make it working on a global scale is much more effort as the data quality in OSM and how addressing works can be very different for the different countries.

BTW: we also provide our own geocoding which is based on photon an open source geocoding projects where we also invest, additionally to financially supporting the 'main' OpenStreetMap geocoder Nominatim project.
Let me say up front that I really dislike the Slack app, but I do think this comment is unfair on Slack.

For them, the biggest lever to improved user experience is almost certainly _product features_ not performance or native integration.

As much as I'd like drag and drop support or less RAM usage, Slack are mostly trying to convert people who have never used instant messaging in the workplace to using it daily (which I think is overall a win), and mostly trying to make users who are not as comfortable with software as we are use a new piece of software.

As an example, when I share a Google Docs link in Slack, I get a prompt from Google Docs _in Slack_ with a one click button to "fix" sharing so that those in the channel will be able to see it. That feature is probably vastly more impactful than improving system integration.

For there to be features like that, or an ecosystem of third party integrations, speed of development is likely a huge factor, and for that, being able to share the codebase across web and desktop apps is likely a no-brainer.

As much as I'd love to see a more performant Slack, it's likely that it would have large negative impacts on the speed of iteration elsewhere, and so I can understand why they don't do it.

Yes there are faster Electron apps, but typically they manage that by... not being Electron apps in certain areas, and sacrificing adaptability for that.

Also, Slack doesn't change _that_ much right?! Well yes and no. As an end user we probably only get ~10% of the changes – 90% may be experiments that never see the light of day but still have to be built in order to find the 10% that are worth it. And even then, assuming the new features are only designed for ~50% of users, because users don't typically use every feature of a product, you'll only actually see 1 in 20 changes that the Slack team build.
Why not both? The Green New Deal doesn’t exclude nuclear power. I know some policy makers are hesitant about nuclear power, but from what I understand the authors of the Green New Deal framework (AOC and Markey) have said they are open to nuclear power.

Something you could do to be better than Google Maps would be to prefer stoplights over two way stops for left turns. That nearly got me sideswiped in SF once.
It doesn't really matter if the last three digits are just noise for the time being. It's just as practical, from the programmer's standpoint. 64 bits worth of nanoseconds gives abundant range (±292 years from the origin) and microsecond times already necessitate a 64-bit representation (2^31 microseconds only gets you half an hour). So you can build all your protocols around signed 64-bit nanos from a defined origin and never need to change it again.

The price of a cluster similar to the one OpenAI used is orders of magnitude higher. We are talking about a price tag that at the very minimum would be in the 150M+ range, you can probably multiply that price by 2 or 3 (10 thousand V100, 300k CPUs, infiniband between every node, network storage etc.).

Almost no one has that kind of money to invest up front (especially not an hypothetical open source organization like discussed here).
Even if somehow one had that money available, for this to be more economic than renting you need to have it running at full capacity at all times for years, not many research groups can come up with many interesting projects at a scale large enough to utilize that kind of cluster efficiently.

So buying something like that is only conceivable for huge research groups with hundreds of researchers and tons of cash: Google Brain, DeepMind, Microsoft and probably Facebook. Even OpenAI wasn't able to afford it directly...
Intrinsic vs extrinsic motivation.

It's pretty common for someone building a library to do so for the utility, scratching a real itch. Not universal (people build libraries to be someone who built a library, too), but common.

It's very common for agencies to be building client projects in order to bill for it. Sometimes there's a special alignment where the client is also primarily interested in spending an allotted budget so long as there's a plausibly adequate deliverable.
The description is actually not very good.

Input lag doesn't purely exist because of liquid movement and pixels changing colors. If it would, then an input lag of 50-100ms (which where common with older generation LCDs) - would also mean the screens response time (the time to change color) would be that high. Which would mean your picture would be a blurry mess.

The majority of input lag came from additional signal processing algorithms which were built into LCDs, which buffered the full picture for 1-2 frames. E.g. to apply overdrive algorithms, color correction, scaling, etc. Those are all running before the signal gets towards the crystals.

I think a lot of that was actually just bad design in the earlier generation of LCDs. And it was really bad, I had a screen with 100ms input lag and neither working nor gaming on it was really fun.

But it seems like manufacturers now understand the problem better and try to minimize the delay through signal processing.
That's the whole point of nuclear, hydro or coal though, they need to be run at high capacity to be economically viable, have long spin up and down times and are costly to maintain. You use them as the basis of the grid and use wind and solar that are more prone to fluctuations to fill up the demand when necessary, less batteries needed as the base load can always be delivered by nuclear/hydro. Coal is basically dead in the next decade or so.

>Of course you could understand the dynamics of a hurricane by analyzing each individual particle

that's actually an article of faith because scientifically speaking we can't. And that's important because it's where reductionism subtly goes from being treated as a scientific method to a sort of belief system.

It's not actually obvious at all that say, complex mind states or intentionality can be reduced to physics. It even seems extremely unlikely, because there's no conceivable way to me how the 'aboutness' of intentional mind states are supposed to be reduced to particles.

Another good example is maybe life itself. Schrödinger in his book What is Life? categorised life as local 'negative entropy', ordering matter at a local level and exporting excess entropy to the outside, in a sense locally 'breaking' the second law of thermodynamics. When our civilisation warms the planet up and produces heat what it really does is exporting disorder, I think it's quite a good description actually.

Aside from the fact that we scientifically haven't proven it, it's hard to imagine how this sort of top-down causal behaviour and complexity is supposed to be reduced to mostly linear particle interactions.
