Boeing is looking like an old, struggling company in a mature industry.

This is also suggesting to me that commercial aviation isn't going to be seeing that much advancement going forward, rather than incremental changes at a decelerating rate. Strong headwinds, say from the energy transition, may actually shrink it a lot.

Cosine Similarity in C++ and SIMD
Anecdote from the days switching to the Euro with respect to weights: When I was working at a restaurant with high thoughput at the end of the '90s and early '00 we first had a giant coin sorting machine. That thing was innacurate (hello Egyptian coins of same sizes as ours) due to only measuring size and being not that accurate. Bank notes were counted by hand.

After the introduction of the Euro, all coins were counted in standard sized cups which also fit in the cashiers trays so no swapping needed, the error rate reduced to near zero (at counting, difference between amount on bag and what the bank told us was in it). Also, the machine was 500 grams instead of half a small room.

The same was applied to bank notes, as they also have a standard weight due to standerdized size and production method. This reduced the error rate even further as counting is difficult as it turns out if you want to do it at scale. It also made the task way faster. Theoretically the machine could count the notes in one go, but it mostly reported "error check notes" messages if you did that. Things like thick tape (for repair when the bank note was damaged) was enough to throw it off in some cases.

Those were interesting times, with people buying a 25ct item with a 250 note to not go to the bank to exchange old for new currency. (Fyi, you do not have to legally accept that as the due dilligence needed with high notes would outweigh the cost of the item).

Other anecdote: Also a lot of 50 euro fake notes showed up within months after introduction, easilly cought as they lit up like a freshly washed white shirt under UV light.

I tend to elide this experience - feel free to speculate about my psychology around the event: I do! - but when I had a stroke (in the US) I was seen very quickly.

In A&E (UK for "ER") departments I've seen (half a dozen experiences, mostly attending with others, all for non life-threatening conditions) wait times ~an hour, about which staff were apologetic. (I understand those expectations may have changed under Tory sabotage.)

This whole thread, while interesting, highlights how variable N=1 anecdotes can be. We're poorly served when we base conclusions only on our own experience. (Though I still think US-one-hour guy is a fortunate outlier!)
This has always puzzled me. Why would you make a coin that is very nearly, but not quite, 1/8 oz? It's not a nice round metric weight either.

The Role of the Glymphatic System and Autophagy in Neurodegenerative Disease
And now we can perhaps hash out whether the `lib` in `/usr/lib` is pronounced with a long or short 'i'. I hope I'm not the only one who pronounced it the first way with no real thought, and never noticed until I heard someone else say it with a long 'i' that that was obviously the logical pronunciation.
Only some states allow turn on red, and it's also often overridden by a road sign that forbids. But for me the ultimate test of AGI is four-or-perhaps-three-or-perhaps-two way stop intersections. You have to know whether the other drivers have a stop sign or not in order to understand how to proceed, and you can't see that information. As an immigrant to the US this baffles me, but my US-native family members shrug like there's some telepathy way to know. There's also a rule that you yield to vehicles on your right at uncontrolled intersections (if you can determine that it is uncontrolled...) that almost no drivers here seem to have heard of. You have to eye-ball the other driver to determine whether or not they look like they remember road rules. Not sure how a Tesla will do that.
You are right that anything that needs up to 50000 atomic, short-lived transactions per second can just use Postgres.

Your UPDATE transaction lasts just a few microseconds, so you can just centralise the problem and that's good because it's simpler, faster and safer.

But this is not a _distributed_ problem, as the article explains:

> remember that a lock in a distributed system is not like a mutex in a multi-threaded application. It’s a more complicated beast, due to the problem that different nodes and the network can all fail independently in various ways

You need distributed locking if the transactions can take seconds or hours, and the machines involved can fail while they hold the lock.
Constantly claiming it is not complicated does not make it so. It was populated land - before Greeks, Romans, Christians and Muslims conquered it and ethnically cleansed the Jews from the area. There wasn't one state - in what is Israel/Palestine today, until 1948, was at least Jordan, Egypt, British Palestine and Syria.

You keep oversimplifying. It's just not simple.
Interesting. Specifically;

Barnett was interested in absence before he was interested in zero. The majority of consciousness and perception science over the last century has focused on what happens in the brain when we detect something in the environment. “But this ignores the whole other side of things,” he said, “which is that you can often have experiences of something not being there.” For example, if you go to grab your keys and they aren’t where you left them on the hallway table, you experience absence.

Previously, researchers assumed that absence was represented in the brain by neurons not firing. But recent studies have shown that the brain encodes absence with unique neural patterns.

...

Nieder, for his part, has been obsessed with zero and absence for the better part of a decade. In 2016, he proposed that the neurological mechanisms that encode absence may be shared with those that encode zero. He hypothesized that zero must have evolved from more fundamental representations of perceptual absence. First, the brain had to understand the absence of a stimulus, like a light being off; only then could it recognize “nothing” as a category akin to “something,” but representing everything that isn’t something. Finally, it had to turn “nothing” into a quantitative concept. By understanding how the brain encodes zero, he believed, we might be able to understand how the brain deals with absence.

This "perception of absence" is called Sunyata (https://en.wikipedia.org/wiki/%C5%9A%C5%ABnyat%C4%81) in Hindu/Buddhist philosophy and various Meditation techniques are often prescribed to experience it.

There can be many types of effects in a hypothetical universe.

Imagine a universe like Conway's way of life, where only neighboring cells can be affected in one timestep. Now add to it a rule that all blocks have a color, and the color of all blocks are changed when one block changes color. Now you have a universe with both immediate and non-immediate effects.

I think there is an opportunity for paid submission to all of them (or a selected subset) as an upsell.
I believe that’s an accurate model, with the caveat that it’s all relative. There’s no universal reference frame. So for the photon and his pal photons, they experience time while you (in your reference frame sitting still) are the one moving at the speed of light and not moving through time.

Edit: See below, the photon doesn’t have its own reference frame so they still don’t experience time.

I like to think of the non-verbal portions as the biological equivalents of ASICs. even skills like riding a bicycle might start out as conscious effort (a vision model, a verbal intention to ride and a reinforcement learning teacher) but is then replaced by a trained model to do the job without needing the careful intentional planning. some of the skills in the bag of tricks are fine tuned by evolution.

ultimately, there's no reason that a general algorithm couldn't do the job of a specific one, just less efficiently.
Book Review: From Oversight to Overkill (A Broken System Blocking Breakthroughs)
If you use seconds and light-seconds as the units instead of meters, then the magnitude of the vector is just a constant 1.

Another way of putting that: This isn’t a vector at all, it’s just a direction. Treating it as a vector gives rise to silly statements like “one second per second”, which is yet another way to explain that it’s magnitude 1… because it’s a direction.

In an ideal world there would be no binary blobs. We do not live in an ideal world. Instead the “dogmatic” FSF have compromised and said that if NO ONE can change the binary blob then everyone is equal. Which is true. However, if you can upgrade it so too can the manufacturer, and this is as a whole disrespectful to user freedom as you have no access to the source. Especially in this day and age when firmwares can be updated OTA and some even include backdoors like Intel ME.

Maintainer of Oxen here, we initially built Oxen because DVC was pretty painfully slow to work with, and had a lot of extra bells and whistles that we didn’t need. Under the hood we optimized the merkle tree structure, hashing algorithms, network protocols, etc to make it speedy when it came to large datasets. We have a pretty nice front end at https://oxen.ai for viewing and querying the data as well.

Photons absolutely do not experience time. The spacetime interval of any photon is always zero, and the spacetime interval tells you how much time any particle experiences. Note that it’s invariant.

This is actually pretty funny.
Tesla's sensor suite does not support safe FSD.

It relies on inferred depth from a single point of view. This means that the depth/positioning info for the entire world is noisy.

From a safety critical point of view its also bollocks, because a single birdshit/smear/raindrop/oil can render the entire system inoperable. Does it degrade safely? does it fuck.

> recognizes that training exceptional deep neural networks requires vast amounts of data,

You missed good data. Recording generic driver's journeys isn't going to yield good data, especially if the people who are driving aren't very good. You need to have a bunch of decent drivers doing specific scenarios.

Moreover that data isn't easily generalisable to other sensor suites. Add another camera? yeahna, new model.

Many new startups choose to incorporate in Delaware, US because of its well established corporate law. Institutional US investors will require a Delaware c-corp prior to investment, so if you incorporate elsewhere and then decide you want to raise funds in the States, you will likely need to reincorporate later. Of course there are startups all over the world, but the question is really about access to capital - typically US investors want to invest in DE c-corps. Feel free to reach out if I can be helpful!
Why does 1 syscall per 1 GB versus 1 syscall per 1 MB have any meaningful performance cost?

syscall overhead is only on the order of 100-1000 ns. Even at a blistering per core memory bandwidth of 100 GB/s, just the single copy fundamentally needed to serialize 1 MB into network packets costs 10,000 ns.

The ~1,000 syscalls needed to transmit a 1 GB file would incur excess overhead of 1 ms versus 1 syscall per 1 GB.

That is at most a 10% overhead if the only thing your system call needs to do is copy the data. As in it takes 10,000 ns total to transmit 1,000 packets meaning you get 10 ns per packet to do all of your protocol segmentation and processing.

The benchmarks in the paper show that the total protocol execution time for a 1 GB file using TCP is 4 seconds. The syscall overhead for issuing 1,000 excess syscalls should thus be ~1/4000 or about 0.025% which is totally irrelevant.

The difference between the 4 second TCP number and the 8 second QUIC number can not be meaningfully traced back to excess syscalls if they were actually issuing max size sendmmsg calls. Hell, even if they did one syscall per packet that would still only account for a mere 1 second of the 4 second difference. It would be a stupid implementation for sure to have such unforced overhead, but even that would not be the actual cause of the performance discrepancy between TCP and QUIC in the produced benchmarks.
Do you stash or create a commit with potentially partial work? What do you name that commit?

But exercise does use lots of energy. Probably more than stress.
Ouch. Once can happen, twice in a row...
My understanding is yes.

However moderate exercise (and stress!) stimulates the body to activate trash/repair/rebuild mechanisms which improve health overall.

EDIT:

For example, aerobic exercise stimulates capillary growth lowering pressure required for blood flow.
Periodic, moderate fasting triggers the elimination of accumulated fats which might have toxins built up in them (or have oxidized)
Healthy, emotional stress teaches us to deal with inevitable tragedies.

It's not the language it's the context. LLMs could give very different outputs depending on the supplied context. In this case, words "python" and "program" put it in a far better context to solve the problem.

> only sensible way

That's a bit strong. Like most of engineering, it depends. Postgres is a good solution if you only have maybe 100k QPS, the locks are logically (if not necessarily fully physically) partially independent, and they aren't held for long. Break any of those constraints, or add anything weird (inefficient postgres clients, high DB load, ...), and you start having to explore either removing those seeming constraints or using other solutions.
Yes you’re right.. the photon has no reference frame of its own then.

So then that would just apply to massive objects with their own reference frames.
More like having the open source community report bugs, feature requests (ideas) and code until the product is good enough to transition into full commercial.

Re: corpus content, I think we're talking past each other. I'm saying that current models aren't being blindly trained on untrusted blogspam, and that there's a lot of work done to verify, structure, transform, etc. And earlier models were trained with lower-quality content, as companies were trying to figure out how much scale mattered. Now they're paying huge amounts of money to improve the quality of what they ingest, to better shape the quality of output. What they take from Reddit, they're not blindly ingesting every comment from every user. My overall main point stands: we have viable, working, scalable mechanisms to avoid the "pollution" you're worried about.
