Right on: I've used a single Postgres database on AWS to handle 1M+ concurrent users. If you're Google, sure, not gonna cut it, but for most people these things scale vertically a lot further than you'd expect (especially if, like me, you grew up in the pre-SSD days and couldn't get hundreds of gigs of RAM on a cloud instance).

Even when you do pass that point, you can often shard to achieve horizontal scalability to at least some degree, since the real heavy lifting is usually easy to break out on a per-user basis. Some apps won't permit that (if you've got cross-user joins then it's going to be a bit of a headache), but at that point you've at least earned the right to start building up a more complex stack and complicating your queries to let things grow horizontally.

Horizontal scaling is a huge headache, any way you cut it, and TBH going with something like Spanner is just as much of a headache because you have to understand its limitations extremely well if you want it to scale. It doesn't just magically make all your SQL infinitely scalable, things that are hard to shard are typically also hard to make fast on Spanner. What it's really good at is taking an app with huge traffic where a) all the hot queries would be easy to shard, but b) you don't want the complexity of adding sharding logic (+re-sharding, migration, failure handling, etc), and c) the tough to shard queries are low frequency enough that you don't really care if they're slow (I guess also d) you don't care that it's hella expensive compared to a normal Postgres or MySQL box). You still need to understand a lot more than when using a normal DB, but it can add a lot of value in those cases.
Yes, but its not just music. Our senses are very much linked in that we can build a one to one relation of ideas in visual space to auditory space and vice versa. There is a common abstract model we understand so to speak.

Our model of perception is very finely tuned with that of space-time.
> libxev's main design goal was to be allocation-free

Maybe "allocation-free" should be in the GitHub project description instead of or in addition to "high performance".
The game is pretty good about taking things like that into account. Even aside from that, a CRT generally adds no lag of its own, displaying the scanline as soon as it begins receiving it, assuming a stable set of sync pulses.

The company that made Rock Band, Harmonix Music Systems, has amazing beatmatching technology that has been used in countless games and is even available in the newest versions of Unreal Engine, thanks to being currently owned by Epic Games. They've been developing this technology since the mid 90s.

The main difference between CRTs and other display types, is that the other display types are all largely sample-and-hold - they display the whole frame line by line, hold it for an amount of time, then begin the process again. They generally lack the decay that happens with a CRT, where the image fades by the time the next frame is to be drawn. Some displays can do black frame insertion, but this is a poor substitute. It requires double the frame rate of the intended output, and it reduces effective brightness. I'd like to see an OLED display that could simulate the phosphor decay on a per-pixel basis, to better simulate the scanning process of a CRT.
We have had flying aircraft carriers in practice and a far more viable form since the advent of air-launched missiles in 1947.

Today, as several other comments have noted, cargo aircraft launching drone swarms are the most likely future development (along with further missile development). Cargo aircraft have vast capacity in both mass and volume. Drones which dispense with the need to support a human pilot, and can operate one-way / kamakazi mode (though return flight is an option), and often have limited top speeds and ranges, make far more sense than a lightweight (and typically limited-capability) manned fighter or bomber.

Another line of nontraditional aircraft carriers are those based on submarines, with the Japanese deploying several during WWII (these enacted the only Japanese aerial attacks on the US mainland, near Santa Barbara and along the Oregon coast), and I believe there was a Soviet study (possibly 941-BIS) to develop a large-scale submarine aircraft carrier. As with airborne aircraft carriers, submarine-as-missile-launch-platform (ballistic or cruise) is far more practicable.
I fail to see how trying to get more out of Maria would make any thing better for Maria herself.
I’m saying if you have a collection of humanoids and general purpose tooling, you can adapt much faster.

I don’t literally mean retool a conventional production line in one night
Does this work for any device that is using the router?

I assume I have to have OpenWrt installed?
I worked on Cyc as a visiting student for a couple of summers; built some visualization tools to help people navigate around the complex graph. But I never was quite sold on the project, some tangential learnings here: https://hyperphor.com/ammdi/alpha-ontologist
So if a stock price crashes there's no one around to buy the stock, so HFT doesn't help in that scenario. They're not going to reduce the buy/ask spread.

But if a stock is going up, HFT inserts themselves between the buyer and the seller and takes a small cut in the process. I don't see how it helps the liquidity stock, but seems to be more like an HFT tax.

They didn't increase the number of stock shares, just got in between the buy/ask margin.

>I'm sorry you feel forced to download a separate app store, but don't you see how you in the end are benefitting from this change even without using the AltStore?

Not really, so far. Are there any game systems that don't require some level of special hardware to back them up? Dreamcast? I don't think I know anyone who has ever made themselves a 'backup copy' of a game they've purchased, much less then played that backup copy on another device. I'm sure they exist, but in numbers even smaller than linux isos on BitTorrent.
Cyc is one of those bad ideas that won't die, and which keeps getting rediscovered on HN. Lenat wasted decades of his life on it. Knowledge graphs like Cyc are labor intensive to build and difficult to maintain. They are brittle in the face of change, and useless if they cannot represent the underlying changes of reality.
At first I found it weird that the BPPE can't discipline a company until it's registered and operating legally. So for the first few years, it couldn't do anything. The twist is that until the BPPE approves a school to operate, any student debt obligations up to that point are not valid. In theory, anyone in California who enrolled before August 2020 owes them nothing.

The problem is that Lambda School still tries to service those debts. The victims are usually low-income, so they lack the resources to lawyer up. If they do lawyer up, they end up being forced into arbitration due to an arbitration clause in their student agreements.

So in the end, it does feel like the BPPE is a half-measure that doesn't fully tackle predatory companies.
Nobody said it was easy.

But you do have to setup and operate a company to run a store or sell an app.

Adding non-profit on top in many places isn't that much more effort.
Interesting that they're still using Allegro Common Lisp. I would be interested in knowing what technical issues (if any) prevented them from migrating to other implementations.
Barrier to entry is very low in terms of leveraging existing tech. You can make a venture funded app just by building a wrapper around OpenAI/Anthropic, etc.

What's different is that AI is a far broader field than dot-com era businesses, so many people will be lost in the shiny hype-stuff and fail to see the true scope of what's changing.

AI is about creating intelligence, and intelligence is the source of all innovation, developing, technology, invention, art, etc. in the world. It's clear to see that with all the benchmarks AI is surpassing humans in, one by one, despite decades of people saying such feats are impossible, that AI overtaking human intelligence is inevitable.
First time probably ever that I've had to disable Javascript because of the creepy and distracting mouse thing. It really feels like you're invading other people's privacy, and if it doesn't, having things randomly move across your field of vision makes it difficult to read.
"Honorable mention" at the end made me lol
i look forward to the optimized version, petite bite.
Intensively managed agricultural land, often doused with pesticides, sounds very different, Maeder said: “The soil becomes quiet.”

So true. In a (healthy) forest, listen & look around. There's always something moving: beetles or centipedes crawling around, moths, mosquitos flying, a woodpecker doing its thing, a mouse rustling through the undergrowth, etc etc. Dig in the soil, and it's a complex web of half-decayed organic matter & critters feasting on that (and each other!).

Now go sit in a corn field: besides maize plants' leaves rustling in the wind, or noises from a nearby road or farm, you hear & see nothing. No insects, no birds or small mammals, nothing. Dig in the soil, and difference with the forest is reflected in there.

"Grief" is the correct word here.
> Zero tolerance policies are a direct response to discrimination claims.

Source? Because if that's true, that's the wrong implementation of a great policy (anti-discrimination).

That's basically saying "well instead of having a policy of reasonable punishment for a given situation, we'd rather be as extreme in our punishment as possible so that we can still hurt kids we hate"

Anytime you hear somebody claiming that university endowments aren't being used or aren't fully being used to aid students, you can safely dismiss their other opinions as being uninformed.

There's a lot of articles out there about what endowments are and the restrictions on how they can be used, e.g.

Their name change was unrelated to this. Somebody else owned a trademark for Lambda and sued them over it, so they were forced to change their name.
I am not surprised that a colossal moron like Turner would spin disallowing warrantless spying on American citizens as guaranteeing “constitutional rights to our adversaries”.
Maybe Amazon changed from scanning palms to scanning ...

NEVER MIND.
Yeah. Avoiding templates almost certainly leads to losing run time performance. The compile time is a drop in the bucket.
Good riddance.

A group of scammers without specialized education, theorizing about immortality (from people without medical education), saving humanity (thank you, but humanity thrives without your help), about ethics in artificial intelligence (from people who do not know any programming language), about drug promotion (from professional drug abusers), about pumping money into cryptocurrencies (which they personally purchased) and even crypto exchanges they own (hello SBF).

I hope to see all these people in jail (as I see they have already removed their names from the site).
Hospitals have become a sort of a standardized customer
CRT has zero input lag from signal to phosphor (maybe a few nanoseconds due to speed of electronics and the electron beam itself) but it will take a few milliseconds to scan an entire frame.

With vsync enabled I guess you could have effectively lower input lag from a well engineered 500hz digital display, when considering lag for complete frames.

If the system is fully engineered to race the beam then you can't beat zero input lag for CRT on mid scanline.
> What else do you propose is going to happen though?

Not parent but I don’t think that we should be holding anyone pending trial when what they’re accused of is so minor, child or otherwise.

Furthermore any decisions about pre-trial detention shouldn’t hinge on remorse or contrition, they should hinge on the alleged offenders risk of flight and their potential risk to the community.
This is great. But I hope they do the same thing to so called "legitimate" universities who have long deceived students as to the value of the degrees they grant.

I recently met a liberal arts student from an Ivy League university who has been under-employed for twenty years. She still has unpaid student loans and she graduated in 2007! She has had to work in retail positions from time to time. And she's considering retraining via a vocational school to be an electrician because that's what her father and brothers do and they make 300K+ a year via the family business.
I had the same problem. I had to long press the download button and open in a new tab for it to do anything. It then showed the popup saying I needed to allow installation of the app in the settings before long-pressing download again.
Apple keeps flogging 8GB RAM for its Mac computers but it's still a dead horse
Also, it can get up off the ground by itself. I don't think I ever saw any of the previous Atlas robots doing that, and it's an important feature, since the primary failure mode of a bipedal robot is falling down.
this is awesome, congratz! I'd love to hear more about the idea!
Yea there is no way. Everyone seems to be misinterpreting the situation.
Is the author here? Can you give us a toggle so we can turn off the moving cursors? It's a little distracting. Reader mode isn't working so well, so I deleted the element in developer tools in the mean time.
To be honest, after the vote I didn’t really keep up as I thought (hoped) real change would take ages to kick in. Guess we’re finally, actually out. Will request a refund.
Modern conveniences is right. Everything is two factor authenticated now. Even if you avoid that in your private life your workplace is liable to roll it out if they haven't already.
> the corporate death penalty

This is a silly idea lobbyists love because it sidesteps the actual corporate-destruction mechanism: liquidation to pay massive fines, license revocation and/or personal liability for senior management.

Consider even the penalties here, which effectively ban Allred and Lambda from doing business. If you corporate death’d them, the contracts and assets would still exist. Allred would be unpunished. Everything would go back to shareholders who were presumably fine with the status quo, and would be fine putting them into a new entity that Allred could manage. Okay, so you cancel the contracts. Now the janitor who hasn’t been paid in two months is screwed. Okay, so you exempt employees. Allred’s an employee! Exempt him? What do you even pay the janitor with? Okay, exempt some assets. How many? How do you choose who must keep paying versus who is let off? Maybe pro rata? Who will administer all this? Et cetera, et cetera.

Contrast that to a massive fine. Company goes Chapter 7 and into a deep body of law that has experience dealing with the above. (Ideally paired with a license revocation from any lending for Allred and the entity, in case they try to Chapter 11.) Shareholders are wiped and free to pursue Allred. Allred and Lambda are neutralised.
Do Best Practices Matter?
Maybe, it's not out of the question that some would do that but I've never had the feeling it was common or desirable even then. GP referenced the '90s hence my guess.

A late '80s Micro TAC, especially with the fat battery, still easily qualified for my previous description. You'd have to go to the early '80s brick phones to get just 1h of talk time from a charge but then again realistically very few people actually talked that much on the mobile in those days when even the networks would have severely limited you. The real sticking point is more that turning off the phone to cut standby time wouldn't have really saved anything for talking time within a day, until you had the time to recharge.

I think the worst thing was the memory effect, where instead of conserving battery you'd actively try to drain it when you had the time so you could charge it from 0.
Japan, the country whose GDP hasn't grown in 30 years, has 0 major tech companies, still uses fax machines for everything, and has numerous stagnant, conglomerates/trusts/monopolies, does capitalism really well? I feel like this comment comes from another planet.
Sure, I don't think anyone was claiming infallibility.

I think it is easy however to romanticize these such errors made in the pursuit of truth.

It can be like the pointing out the fallibility of Galileo Galilei in thinking he wouldn't be held to the inquisition, and made to recant his evidence of heliocentrism.
Tonsky's website is infamous for making a mockery out of modern UX. That's also why toggling dark mode turns your pointer into a flashlight. I agree the mouses are distracting and I always use reader mode when browsing his site.
Sure, we have that discussion and I answer and we set clear boundaries.
I saw some Mr Beast branded candy bars at the supermarket this week. Pretty sure that's not a future-saving venture, that's just taking advantage of the sugar-addicted kids that form his fanbase.

Ha, excellent. This needs a Wat video. I heard the sound in my head on every misalignment.
> Deferred or alternative scenario planning should be adopted, especially for large and expensive queries. As it is today, your plan is finalized before it is executed, even though earlier stages of execution could provide information (like rowcounts or cardinality estimates) that could dramatically improve later stage plans.

Alternative planning sounds awesome. I saw a query plan the other day where it expected about 1000 rows from some subquery so did a nested loop to an index scan. In reality there’s about a billion rows. I’m not sure yet why the estimate was so bad, but being able to pivot from a nested loop to a hash join if the row count crossed some threshold would be great at avoiding some catastrophic plans.

He seems to be the king of technically.

"For a few months in 2013, Allred camped out of his car while in Silicon Valley, and frequently describes this period as having been homeless. However, a deleted post on his blog titled 'Voluntarily Homeless in Silicon Valley' explains that he lived out of a car by choice."
The “car wash mode” just does a few things that are important to an auto car wash: allows the vehicle to roll in neutral (so the tire pushers can work) without shifting to park, turns off auto wipers, disables the charge port from opening, and disables any of the assistants so they don’t potentially freak out from spraying water and moving components nearby. Seems like this is a simple CYA statement so if the car wash rips off the charging door or windshield wipers that Tesla isn’t liable. Seems quite reasonable to me.

What caused the storm that brought Dubai to a standstill?
A storm hit the United Arab Emirates and Oman this week bringing record rainfall that flooded highways, inundated houses, grid-locked traffic and trapped people in their homes. [...] In the UAE, a record 254 millimetres (10 inches) of rainfall was recorded in Al Ain, a city bordering Oman. It was the largest ever in a 24-hour period since records started in 1949. Rainfall is rare in the UAE and elsewhere on the Arabian Peninsula, that is typically known for its dry desert climate. Summer air temperatures can soar above 50 degrees Celsius. But the UAE and Oman also lack drainage systems to cope with heavy rains and submerged roads are not uncommon during rainfall.

Following Tuesday's events, questions were raised whether cloud seeding, a process that the UAE frequently conducts, could have caused the heavy rains. Cloud seeding is a process in which chemicals are implanted into clouds to increase rainfall in an environment where water scarcity is a concern. The UAE, located in one of the hottest and driest regions on earth, has been leading the effort to seed clouds and increase precipitation. But the UAE's meteorology agency told Reuters there were no such operations before the storm. The huge rainfall was instead likely due to a normal weather system that was exacerbated by climate change, experts say. A low pressure system in the upper atmosphere, coupled with low pressure at the surface had acted like a pressure 'squeeze' on the air, according to Esraa Alnaqbi, a senior forecaster at the UAE government's National Centre of Meteorology. That squeeze, intensified by the contrast between warmer temperatures at ground level and colder temperatures higher up, created the conditions for the powerful thunderstorm, she said.
Didn't know Tesla employed buffalos. Maybe that's why they've got manufacturing problems -- not enough manual dexterity.
This seems similar to semi-structured (aka 2:4) sparsity, may be worth explicitly comparing. As far as I can tell by skimming, your technique:

- is optimized for apple silicon
- ~2x speed at 75% sparsity
- dynamic, depends on input, applied at runtime
- can choose amount of sparsity

And 2:4 semi-structured sparsity:

- is optimized for GPUs with sparse tensor cores (nvidia ampere and beyond)
- ~2x speed at 50% sparsity
- static, applied to the model at rest
- probably worse results than your technique at 50% sparsity

The interesting comparison I'd want to see is semi-structured sparsity results (50% sparsity, 2x speedup) vs your results at 75% sparsity (2x speedup).
Yes, but I think the post-brexit transition phase tricked me into believing the change wouldn’t be this drastic. Sigh.
It doesn’t need to be this way. Essentially all UK universities are “public” and none operate this way. There aren’t special police forces that roam their campuses (Oxford had this for a time, but I think it was the only one). Violation of university rules is no more serious from a legal perspective than violating any other private rules.

I think campus police are an insane idea. There should obviously be a good relationship between any university and the police in their area, but the idea that they should report to the university leadership is nonsensical.
> Nobody said it was easy.

Yes, you did: "not that much harder than setting up the account in the first place" and "isn't that much more effort".

> But you do have to setup and operate a company to run a store or sell an app.

No, you don't actually have to setup and operate a company to sell an app.
Hospitals in my area of the US still use POCSAG pagers, totally unencrypted. They do mention patient information, but I guess the obscurity makes it ok.
GraphQL isn't exactly a proper graph database query language. The name IIRC comes from Facebook Graph API, and the language isn't actually designed as graph database interface.
> when deprived of their attack transient, the sounds of two different instruments may become hard to tell apart

A neat trick is playing guitar through a volume pedal. You mute the sound, pluck a string and then swell in the volume pedal. The rest of the ASDR envelope can be created with other effects like delays.
It officially occurred at the end of January 2020. I think something else important happened around that time that made it easy to miss :) Pre-existing law (e.g. GDPR) continues to until we remove it. New regulations like the DMA won’t ever apply.

A real piano is also profoundly lacking in expressive control over timbre (excluding extended techniques like half-pedaling or directly touching the strings that hardly ever show up in the repertoire). The only control the piano gives you over note timbre is how hard you press the key. Once you've done that, the hammer disconnects from the key and flies through the air out of your control.

A keyboard with polyphonic aftertouch, such as the Yamaha CS-80 (famously played by Vangelis), is objectively more expressive than a piano.
