> Instead it is better to optimize for the space already available (Segwit is an example).

Segwit doesn't optimize already available space, it bypasses the original 1 MB block size limit by moving the transaction signatures outside of the limit (which it does in a way that has some security advantages). Main difference is that it was done as a soft fork, not as a hard fork (which would split the chain). I don't think that you can optimize the size of blocks, as they contain mostly address hashes and signatures.

You can see here that the blocks are bigger than 1 MB: https://www.blockchain.com/explorer/charts/avg-block-size
In theory, S/MIME and SMIMEA. In reality, normal users demand account data recovery in cases of lost encryption keys and passwords. So key escrow is required, which isn't E2EE. ProtonMail tells forgetful users to shove it, which limits its adoption; meanwhile ProtonMail also supports webmail (another feature requirement) which decrypts messages in the browser, weakening any E2EE claims.
You forgot Chromium happened because of WebKit happened. WebKit happened because of KHTML.
There's not much independent news coming out of Russia, and the Moscow Times itself was recently banned in Russia.

But I've been noticing intense wildfire activity in Siberia through the Nullschool Earth Weather Visualiser, e.g.:

Particulates (PM1) <https://earth.nullschool.net/#2024/07/15/0000Z/particulates/...>

CO (rapidly-attenuating signal of combustion): <https://earth.nullschool.net/#2024/07/15/0000Z/chem/surface/...>

NO2 (more slowly-attenuating combustion signal): <https://earth.nullschool.net/#2024/07/15/0000Z/chem/surface/...>

Moscow Times confirms my suspicions.

Canada's also seeing major wildfires, largely in British Columbia:

Try it out - don't trust me!

The way this works is that each device holds a partition of the model (for now a continuous set of layers). E.g. let's say you have 3 devices and the model is 32 layers. Device 1 could hold layers 1-10, device 2 holds 11-20 and device 3 holds 21-32. Each device executes the layers it's responsible for and passes on the output of its last layer (the activations) to the next device.

The activations are ~8KB for Llama-3-8B and ~32KB for Llama-3-70B (it's linear in the number of parameters in that layer and Llama-3-70B has more layers). Generally the larger the model gets (in terms of parameters), the more layers it ends up having, so we end up with sub-linear scaling so I expect Llama-3-405B to have activations on the order of ~100KB.

This is totally acceptable to send over a local network. The main issue you run into is latency, not bandwidth. Since LLMs are autoregressive (tokens are generated serially), additional latency limits throughput. However, over a local network latency is generally very low (<5ms in my experience). And if not, it's still useful depending on the use-case since you can get a lot of throughput with pipeline parallelism (overlapping requests): https://pytorch.org/docs/stable/pipeline.html
You are asking for someone else to do a demo of something trivial that takes 15 minutes to setup yourself (with Vite). Nobody is biting because it’s a strange (and, frankly, lazy) request.

If you tried and still think such a setup is not possible, send me an email (in profile) and I can do a 10-15 minute show&tell.
This is a non-answer in a way, because it's set in the past.

I think it might have been in the early '90s - certainly it was when mobile phones were new and faddish and the province of people with more money than sense. There was an earthquake in Thailand, and newspapers reported that survivors were calling for help from inside fallen buildings ON THEIR MOBILE PHONES. At the time I thought that was the most purely science-fictional real event I'd ever heard of.

These days, of course, I've got to stretch my mind to see why that should seem even slightly unusual.
Perhaps if Feynman could recommend educational software, he'd choose a programming language. I think the best educational tools are real-world creative tools. This includes access to knowledge.

It might be that exploring new physics might be best pursued by inhuman alphago-style setups.

> Are you saying that there's some, albeit weak, predictive power in HN comments?

I do claim that there is at least some (though far from perfect) predictive power whether a product or service will be liked or disliked by "hacking-minded" people. Also, because such people are sometime more vocal than the general population, I can imagine predictive power to exist whether some (planned) product or service will tend to cause controversies (in the future).

But it should be obvious that this is all about a specific market segment and target audience: there exist quite a lot of commercially successful products and services for which are not particularly liked by hackers.
Having worked in both quite a bit I think Flutter is a more polished and stable tech stack. But RN might be easier if you already know React.
Good times. We also got a Convex after the FPS AP-120 attached vector processor ran out of steam. The Convex guys were great to work with, tho they always traveled to us. Later, in a different life, I deployed a number of HP V-series boxes, which were in a sense the grandchildren of the Convexen.
I'm not sure I've met a consumer of diagrams who ever really wanted to know what's going on, so much as they wanted to have their pre-conceptions validated for the brief time they're interested in the problem.

I have had too many conversations with managers who want to talk about "pipelines" but then you ask how the system is handling dropped or failed messages and get a deafening silence or "just don't worry about it it's rare".

People love arrows showing the "direction" data is going, but do things like assume that direction means "security" (it doesn't - any channel other then a full on data-diode is 2-way) or implies other operations (i.e. about storage).

I wonder if Gmail and Outlook interop on Emoji Reactions.

Gmail launched the feature in 2023[1].

I’ve personally not used the feature but emojis shouldn’t be images — they are after all Unicode code points. Not sure why MS’s implementation uses images at all.

"Our first product will be the world's obviously best AI course, LLM101n."

Well obviously the target audience is actually AI-agents as part of the Super Intelligence ramp-up!
I'd settle for either one. In order to have have a context at all, one must have some critical mass of understanding. The density of parts I can understand is never enough to achieve that.
My experience is that any portion of Shakespeare that I attempt to read goes the same way.
If I dig farther into "mutiny", there's no way to know if I'm eventually going to produce a "context" or whether I'm on a fool's errand.
In order to develop a context, one must somehow achieve a sufficient foothold of comprehension from which to build it.
There are precious few sentences in Shakespeare for which I would be able to do that. The farther you get into the play, the more references there are to earlier, so you kind of have to start at the beginning. But I can't understand that part either.

You keep saying it's easy. I believe you when you say that's your experience. What I'm trying to tell you is that it's not easy for everyone. There is no amount of patience that I could apply to this pursuit that would yield success.
This is my good-faith best effort to comprehend it and it's not happening.
> The purpose of price discrimination is to reduce the share of gains-from-trade received by consumers to zero.

Even from a cynical perspective, that is incomplete, since it doesn't capture another purpose--which you mentioned in passing--of "better a little profit than no profit", where a lower price is offered to permit trades that would otherwise not occur.

> Given this, it's not really clear why price discrimination is supposed to be beneficial.

Leaving aside whether a net-effect or national policy is good or bad, surely you can imagine some individual cases where "price discrimination" is used for good, right?

Suppose the local baker wants to offer extra bread to the poor for a symbolic pittance, without impacting the price he usually sells it at to regular customers. It is both a charitable act and also pricing-discrimination: "The really poor" are identified, and a separate price of $0.25/loaf is offered.

> Lower rates for bulk purchases is not an example of price discrimination.

Huh? Bulk-rates are literally a textbook example of price discrimination, albeit usually with the qualifier of "second-degree." [0]

If you still think it shouldn't count, then what's the rationale that sets it apart?

It can't be based on "the conditions were publicized in advance", because if that's how it works then "rich people pay more" would magically cease being price discrimination just because I put it on a sign.

Another possibility is "because it represents actual cost differences to the vendor", but I don't see that as very compelling, since (A) sometimes those don't meaningfully exist like with "digital goods" and copyright licenses and (B) that would excuse certain kinds of price-discrimination as long as the vendor can argue a smidgen of logistical difference in the deals.

Open source of the sales strategy of 500 top tech company at early stage
I’m building a B2B Fintech product where we provide SDKs to Fintech platform to perform rate limiting on their endpoints dynamically. Basically selling is quite hard, I have tried different strategies and still I have low turnouts, though we have managed to reach an MRR of almost $1k, it’s no where near we are meant to be.

And that got me thinking, conventional methods of sales only gets you conventional results, trying out something new, or something someone who has built a billion dollar company did differently from the crowd is the way forward these days, cause quite honestly, the conventional methods are no longer yielding good results anymore.

So that got me thinking, since I would gladly pay for someone to help me implement the sales strategy the CEOs of Stripe or Forter did in their early days, why not scrape the internet and build a list of all those playbooks, alongside with the total amount it took to implement them and other details and open source that?

What do you guys think? would you also like this?

Nope. There's a difference between being sad and being clinically depressed, there's a difference between being distracted and having ADHD, there's a difference between worrying and having OCD, there's a difference between not wanting to eat a particular meal and having anorexia or ARFID.

> Education [...] should be egalitarian

It is self-evident to me that this is not true in the U.S.

There is very little about education that is egalitarian. An inner city grade school in Michigan is in no way comparable to a grade school in the Palo Alto suburbs.

> Such that no one is left out or treated better if you didn’t happen to go to an “AI” school makes for a tough hill to climb.

To drive this point home, in the real world we do not hold this standard for air conditioning. Tens of thousands of schools in the U.S. do not currently have adequate HVAC systems. If we are not currently applying this standard to A/C, I don't know why we would choose to selectively apply it to AI.

Attempting to gate innovation behind complete social conformity and universal adoption doesn't strike me as a rationale stance.
Slack should add an option to disable reactions for people like this. However, since the sender is expecting their reaction to be seen, Slack should then replace the reaction with a text message matching the reaction: "Ok emoji", "Thumbs up emoji", "Smile face emoji", etc. so that the reaction doesn't just disappear and the intended recipient sees it.
We as a computing populace are getting more and more comfortable with footguns.
You are just giving them ChatGPT with a bit of prompt engineering, and evaluating them on math problems, which we know LLMs make errors on because they are not calculators. You aren't putting in the effort needed to build a real tutor and learning assistant. I would not extrapolate from these results

There are also a lot of things that can come in before you build a full on tutor. One example is being able to tailor word problems (transform the nouns) to subjects interesting to the particular student. They could also be used to help understand where students are struggling. We are still at the early phases of useful AI, optimism is more appreciated, especially as contemporary times have become so pessimistic

> I don't know if CP/M (and in turn CMS) was inspired by UNIX in that way, or whether the "file" concept came from a different common ancestor, […]

CP/M drew heavily on DEC operating system designs, notably RSX-11M – it even had PIP as a file «manipulation» command as well as the device naming and management commands (e.g. ASSIGN). Perhaps something else. MS-DOS 1 has descended from CP/M whereas MS-DOS 2 diverged from it and borrowed from UNIX .

> […] but it's worth repeating that MVS has more or less nothing like that "file" concept.

Ironically, the today's blame that [nearly] everything is a file and a stream of bytes in UNIX is the root cause of all evil was the major liberating innovation and a productivity boost that UNIX has offered to the world. Whenever somebody mentions that stderr should be a stream of typed objects or alike, I cringe and shudder as people do not realise how the typed things couple the typed object consumer with the typed object producer, a major bane of computing of old days.

The world was a different place back then, and the idea of having a personal computer of any sort was either preposterous or a product of distant future set science fiction.

So, the I/O on mainframes and minicomputers was heavily skewed towards the business oriented tasks, business automation and business productivity enhacements. Databases had not entered the world yet, either, and as they were still incubating in research departments of IBM et al, and the record oriented I/O was pretty much the mainstream. Conceptually, it was the overengineered Berkely DB so to speak baked into the kernel and the hardware, so it was not possible to just open a file as it was not, well, a file. In fact, I have an opened PDF on my laptop titled «IAS/RSX-11M I/O Operations Reference Manual» that has 262 pages in total and has 45 pages in Chapter 2 dedicated to the description of how to prepare a file control block alone required just to open a file. I will take an open(2) UNIX one-liner any time over that, thanks.

Psql and AI = inline text-to-SQL, query optimization and SQL assistant
I've had the same thought but then gave up because it's not even a single graph: we assume it's a single graph because some parts of "concept - connection - concept" tuples...but that fails to capture the reality that the aggregate behavior of a system can implement a wholly different behavior.

A practical example of this would be neural networks in AI: which collectively implement functions much greater then the individual links.

You are not wrong and I agree with you that this sort of bullshit is laughably unacceptable.

Unfortunately nothing opt in ever gets wide adoption. So I expect to keep seeing these sort of infernal acts as people get bright but misguided ideas that require broad adoption to work. for example googles wifi cataloging does not work at all if to get cataloged you have to put "_cataloged" in your ssid.

According to a random website[1] a Falcon 9 launch uses about 312 tons of liquid oxygen. Assuming that all gets converted into water that’s about 350 tons of water. Wikipedia[2] says there were 223 orbital rocket launch attempts in 2023. Almost half of those were Falcon 9, and if we assume for simplicity that the rest average out to around the same amount of water per launch that would give about 78 thousand tons total.

So about three orders of magnitude less than the one eruption.

>Are you interested in living in a malthusian nightmare?

Some of them live in such an environment already. I don't know if it's a hallucination or not, but judging from what I've read here over the years a lot of tech people seem to live in the most cutthroat of environments and see everyone as competition to be eliminated or obstacles to be cleared. Some of them live in an environment where you can rely only on yourself, requesting help is seen as weak victim-like behavior, but giving out for free is worse - detrimental because that other person might see what you're doing and take credit for or steal your work; some say helping another with your skills/time and not charging money is peak cuck behavior, and some of the more organized (I'd like to say 'coeficient-driven') members of our community really believe that money is the greatest measurement tool ever invented and we should measure everything with it, including a person's worth.

That being said, generalizing is bad and there really are some truly golden individuals here who have done humanity a net benefit while charging nothing for their work. Like Fabien Sanglard, for example (you likely will never read this but I take my hat off to you and I hope if you get the chance, you should clone yourself in the future - humanity could use at least 10 of you).

I'd find quotes for all of these but I don't think I need them, you've seen these messages if you read the HN comments enough.

Man runescape was my life for a long while. Its still the only MMO I know which actually has unique and rewarding quests, activities, and mini games. There's something like 150 quests, most with completely new NPCs, new map environments/interactions, item, skill and map unlocks. For example to gain access to the best sword in the game (at the time) you had to do a quest where you were travelled to a monkey island where you had to sneak around, be creative, defeat a bunch of apes and the boss. And it was actually fairly difficult, you had to prepare for the quest and dying meant losing almost all your items. Nothing like go here kill 20 foxes, come back.
