Interesting! All of my best friends came from going through the same experience together. Totally agree on that. But that experience was high school or college. What experience can adult men (25+) go through that is enough to build a lasting friendship?

That consistent, shared experience what I'm trying to build. But I can appreciate the feedback that it comes across as "auditioning" as that's not the point. The goal is to get people in the same place on a consistent basis. I also believe that consistently hanging out with people who are generally interesting / agreeable is a lot more important than matching humor or hobbies.

How would you position this with that goal in mind, especially considering that some filtering needs to take place since many people won't necessarily click like you say. I'm not going to find someone whose humor matches mine by dumb luck.

What's the bottleneck? Is it serializing to/from pyobjects over and over for the mlops? I thought pytorch was pretty good with this: Tensors are views, the computation graph can be executed in parallel, & you're just calling a bunch of fast linear algebra libraries under the hood, etc.

If it avoids excessive copying & supports parallel computation, surely it's fine?

If your model is small enough where the overhead of python would start dominating the execution time, I mean... does performance even matter that much, then? And if it's large enough, surely the things I mentioned outweigh the costs?

:-) I like the symmetry of this. If I want to keep my creations outside the hands of others, I can keep them private. I don’t have to publish these words or broadcast them to the world. I could write this on my laptop, save it in a file, and keep it to myself. Fine.

However, once these words are broadcast—once they’re read, and the ideas expressed here enter someone else’s mind—I believe it’s only fair that the person on the receiving end has the right to use, replicate, or create something from them. After all, they lent me their brain—ideas that originated in my mind now live in theirs.

This uses up their mental "meat space," their blood sugar, and their oxygen—resources they provide. So, they have rights too: the right to do as they please with those ideas, including creating any and all data derived from them. Denying them that right feels churlish, as if it isn’t the most natural thing in the world.

(Before people jump on me:- Yes, creators need to be compensated—they deserve to make a living from their work. But this doesn’t extend to their grandchildren. Copyright laws should incentivize creation, not provide luxury for the descendants of the original creator a century later.)

Related historical novels about England, full of intrigue, passion, crime, and adultery, what else do you expect, like of any (feudal) period anywhere in the world, but a somewhat light, fun read, now and then. Gotta get those jollies out, and this is one way. Catharsis, IOW :) :

Jean Plaidy / Eleanor Alice Burford

Nah. As more people are rendered unemployed the buying market and therefore aggregate demand will fall. Fewer sales hurts the bottom line. At some point, revenues across the entire economy fall, and companies cannot afford the massive datacenters and nuclear power plants fueling them. The hardware gets sold cheap, the companies go under, and people get hired again. Eventually, some kind of equilibrium will be found or the world engages in the Butlerian Jihad.

I tried and failed to write a knitting interpreter that could take a written pattern and generate a visual representation. You could have variables that expand into larger expressions, and some kind of "syntax highlighting" or verification step to make sure things are consistent.

Interested to know if you've ever tried something like that? I also get that knitting is a hobby many people do to escape computers for a minute.

Anyways, that got me into approaching the problem from a different angle (https://madhatter.app). A visual editor for hat patterns with layering, repeats, shapes, overstitching markers.

Some stuff is broken right now and it doesn't look great on mobile, but I'm building it in real time whenever my partner expresses frustration in some aspect of existing paid software ;-)

> More housing in _that_ model is more people with more cars on the road and needing parking spaces.

The existing model is already that everybody is driving everywhere, and then you need a parking space at every place for the number of people patronizing it during its peak hours. Building more housing doesn't inherently increase or decrease the number of parking spaces you need. You still need one for each car.

What it does is reduce the distance you have to drive, because then you don't have to drive through miles of low density suburbs to get anywhere. Moreover, with mixed use zoning, it puts more of the places you might want to go within walking distance, which does reduce the number of parking spaces you need at the destination.

> The inevitable conclusion to such a model is cities like Houston, TX where everything is twice as far away because 50% of the city is just parking lot and another 25% just roads/intersections.

The "problem" in Houston is that it's in Texas, which is big and susceptible to sprawl. Houston Metro has a population density of ~700/sq mi, compared to ~3200/sq mi for New York Metro. Then land is cheaper and therefore parking is cheaper and taller buildings are less economical. That's what causes everything to be more spread out.

But the problem in higher population density areas isn't parking -- when land is more expensive then you can justify building taller buildings and parking beneath the building or even multi-level parking garages to conserve space. The problem in higher population density areas is that building more of those things is now prohibited. You have a plot of land and you want to put a parking garage with 50 spaces on the ground floor, two shops on the second floor and eight condos on the third floor. You can't, because it's only zoned for a single-family home.

> WAP/WML was a near total flop

Not quite, WAP evolved into WAP 2.0 and WML was replaced with xHTML. For a long period of time WAP 2.0 was the only standard while mobile development evolved. Even as HTML support grew in the mobile space, there was a very solid duration of time where WAP 2.0 was the most supported across the majority of devices and browsers (in the mobile space). And FWIW, I wouldn’t consider WML a flop, because that was the only mobile standard supported on most phones before the iPhone.

I agree with this - but sorta comforting? Like this would imply the AI may only do so if they chance of success was like 1% and the other 99% would give away the cards of it and other future AIs.

I know this is all completely hypothetical science-fiction, but I also have trouble seeing the idea that AI would settle for these long deceptive plans for which it has imperfect info.

The thing I find interesting about a lot of things like this is that they feel like a holdover of half the era where negotiating prices was normal: today, for most people in the US, most shopping is just a matter of going somewhere and paying a set price and you don’t argue with the seller to get a better one. B2B transactions still usually involve a negotiation, I think, but it’s basically gone for consumers.

With something like airfares, the business is still doing its half of negotiations: collecting bits of data about the buyer to determine a price; but, crucially, there’s no real way for the buyer to “talk back” and so the process seems arbitrary.

Not to diminish the work of the scientists, but I think the relevant part of the article is :

"They found that when the flakes are cooled to 300 millikelvins (about -273 degrees Celsius), the material turns into a superconductor"

And the material is a particular form of graphite.

For me, the grail (I know it's a dream) would be a superconductor that works at ambient temperature and pressure.

C# have this feature, it's called roslyn code generator.

I believe your java annotations cannot change the build parameters of the package being currently compiled, which is why you wouldnt be able to do that in java.

btw, anything that is present in the AST could be used for that, but I think the preprocessor directive is the most sensible choice.

I would not say it is trash, but I tend to agree with the general sentiment and personally don't write longer scripts.

> This is also the advice given in the google shell guide.

This advice is also given in this handbook :) But in reality you might come to a work repo that already has such scripts and it is good to understand it a little bit, I would think.

Did not know that! Old article, but:

> However, in the nearly four years since the 4680 battery was unveiled in 2020 and began mass production at the end of 2023, companies like CATL and BYD have reduced battery costs to RMB 0.4/Wh. Even if Tesla meets its cost reduction target by the end of this year, according to multiple engineers and industry insiders, the cost of 4680 batteries may still range between RMB 0.8-1/Wh, which is twice that of CATL and BYD batteries. Moreover, the safety, cycle life, and charging speed of this battery are weaker than mainstream batteries.

> This in theory would be good because it gives American manufacturers a chance to catch up and giving them a huge advantadge for selling to American customers.

That's the tired old 'infant industry argument'. It's just as bad now as it always has been. Compare also Brazil's ill-fated attempt at creating a home-grown computer industry.

> in practice, it didn't work because the US really can't decide where it wants to go with EV's. Fighting over standards, some trying to keep holding things back to sell ICE vehicles, etc.

I'm not sure who you mean by 'the US'? Producers and consumers of EVs should make their choices.

> Inflation also didn't help, so a lot of cars just blew up in cost.

Inflation is a general rise of the price level. If both input costs and prices you can charge to customers go up in proportion, inflation doesn't make a difference. Just like moving from metres to yards doesn't make the distance between London and Paris larger.

To get full value of your money takes time and information in every market. It’s not unique to this space.

If you want to buy anything and just pick the first option then you probably will have worse results than someone that did research. Or someone that used coupons. Or someone that waited for a sale. Or someone that bought used. Etc etc

We obviously shouldn’t make all those behaviors illegal. There is an inherent time/money trade off in life. It’s actually the whole basis for economic activity (ie it’s why employers are able to pay you to do stuff for them) so stopping it would probably be quite bad.

I am a massive caffeine drinker. Like many of us, I monitor my sleep religiously so I have an anecdote. Late afternoon espresso or hot coffee is usually quite sleep effecting.

However - I have found that cold brew does not bother my sleep! At least the brand that I drink. Very strange, but awesome. Cold brew does not have the acidity of hot coffee which is a double bonus if you get acid reflux at night from poor eating or drinking habits. Give it a whirl.

I've had instances now where the code generated by copilot has saved me roughly an hour or more without turning into a can of worms. Your mileage is going to vary depending on the language and framework you're using.

For example, one instance for me was with winforms. I wanted to know how to recursively expand a list box. It's not a hard task, but it's just something that's tedious since I need to go research the documentation to see how a list box control actually behaves and what properties I need to manipulate. This is a very solved problem. What good is there in me re-solving it when someone has already done so?

That's where using AI is helpful without it being foolish.

I think most people would be shocked to know how much glue code is in powershell or bash/perl that kind of keeps everything running.

I remember looking on in horror as a QA person who was responsible for the install/deploy of some banking software scrolled through the bash/perl script that installed this thing. I think it had to be 20k+ lines of the gnarliest code I've ever seen. I was the java/.net integration guy who worked with larger customers to integrate systems.

My group insisted we should do single sign in in perl script but I couldn't get the CPAN package working. I had a prototype in java done in an afternoon. I never understood why people loved perl so much. Same with powershell. Shell scripters are a different breed.

I essentially always find it more useful to do a Google Scholar search and skim a highly cited paper vs. asking an LLM.

A search for `"critical regime" brain` turns up as result #2 https://www.frontiersin.org/journals/physiology/articles/10....

> Relatively recent work has reported that networks of neurons can produce avalanches of activity whose sizes follow a power law distribution. This suggests that these networks may be operating near a critical point, poised between a phase where activity rapidly dies out and a phase where activity is amplified over time. The hypothesis that the electrical activity of neural networks in the brain is critical is potentially important, as many simulations suggest that information processing functions would be optimized at the critical point. This hypothesis, however, is still controversial. Here we will explain the concept of criticality and review the substantial objections to the criticality hypothesis raised by skeptics.

A search for `"critical regime" brain sleep` turns up a review article discussing various studies about criticality in neuroscience, including a section reviewing studies related to sleep, https://www.frontiersin.org/journals/neural-circuits/article...

A similar but "data leaky". one was UC browser. These two were constantly compared back in the day, their entire selling point was faster downloads over opera mini. I remember doing speed tests with both on my old nokia and Samsung feature phones on 2g networks. I'm extremely grateful these browsers exist otherwise I wouldn't have been browsing zdnet, old techradar, w3schools, phpeasystep, betanews etc. while I was 12. They got me into the world of tech and now I am working in it.

Opera mini did support video playback on some phones especially on YouTube. It opens the phone's inbuilt video player with an RTSP link to the 3gp version of the video. I guess it stopped working when YouTube removed RTSP? Oh that brings a lot of memories about real player which was also available on j2me as well as pc.

It reads as racist if you parse it as (skin tone and attractiveness) but if you instead parse it as (skin tone) and (attractiveness), ie as two entirely unrelated characteristics of the output, then it reads as nothing more than a claim about relative differences in behavior between models.

Of course, given the sensitivity of the topic it is arguably somewhat inappropriate to make such observations without sufficient effort to clarify the precise meaning.
Can we take a moment to appreciate what kind of web experience we are building?
by tomdesantis | 2025-05-30 01:04:56+00:00
A web where most posts, images and videos are AI-generated with only SEO optimization, advertisement and manipulation in mind

A web controlled by scraping and crawling agents with advanced browser control designed to deceive paywalls, steal content and send spam

A web were creators that make genuinely interesting content are not rewarded for their work because of the things mentioned above

A web where digital identities are easily faked and weaponized with a simple prompt

I'm afraid that we are trading short term economic gains for a horrible web experience in the long term.

I took a completely different path to visualizing embedding vectors’ physical layout [1] - mainly to explain how the data structures, data volumes and comparison would radically differ, compared to your regular btree index searches. I made sure to mention that you can’t make any conclusions based on just human eyeballing of these vector heatmaps, but the database people I’ve demoed this to, seem to have reached some a-ha moments about understanding how radically different a vector search is compared to the usual database index lookup work:

The thing you're being forced to do is to choose between paying the higher price without screwing around and screwing around in order to pay the lower price, because the option to pay the lower price without screwing around was taken away.

This can be true even if the lower price is nominally a discount. Before everybody would pay $100. Now you can pay $80 by screwing around but have to pay $150 otherwise, and the screwing around is $40 worth of inconvenience. $40 is less than the $70 difference between $80 and $150, but $80 plus a $40 inconvenience is a higher cost than the original $100 uniform price, and obviously so is $150.

Unrelated, but is this a case of the Pareto Principle? (Admittedly the first time I'm hearing of it) Wherein 80% of the effect is caused by 20% of the input. Or is this more a case of diminishing returns? Where the initial results were incredible, but each succeeding iteration seems to be more disappointing?
by Tainnor | 2025-05-30 01:08:22+00:00
You're mixing things up. By a "general theorem prover", we typically mean "a program which can decide for every sentence in FOL whether it's valid" (I say FOL, because the situation is even worse for HOL), i.e. a decider for the set of valid FOL sentences. The sentence ZFC -> CH (where ZFC and CH are expanded as needed) is not valid because CH doesn't follow from the ZFC axioms. Neither is ZFC -> not(CH) valid. We know both of these results from proofs specific to this problem, but a general purpose theorem prover would give us both of these results for free. If we had such a tool, mathematics would essentially be "solved" (maybe apart from deciding what questions to ask). But since FOL is undecidable, it can't exist.

What you are asking for is a machine that for each pair of formulas A, B (correctly) decides that either A -> B or A -> not(B), but this is impossible for model-theoretic reasons (not all theories are complete) and that has nothing to do with decidability.

I wonder too.

It doesn't say so on the DT page here:

https://en.wikipedia.org/wiki/Delirium_tremens

But I read something somewhere that alcohol does something that prevents REM or soemthing, and when you stop drinking your sleep-deprived body wants to make up the REM and will even do it while you're awake.

don't know for sure

EDIT: https://pmc.ncbi.nlm.nih.gov/articles/PMC2778757/

...supports early theories that the hallucinations of DTs represent an intrusion of REM sleep processes into the waking state (for a review, see Zarcone 1978).

https://www.aei.org/economics/what-atms-bank-tellers-rise-ro... Well, the average bank branch in an urban area required about 21 tellers. That was cut because of the ATM machine to about 13 tellers. But that meant it was cheaper to operate a branch. Well, banks wanted, in part because of deregulation but just for deregulation but just for basic marketing reasons, to increase the number of branch offices. And when it became cheaper to do so, demand for branch offices increased. And as a result, demand for bank tellers increased. We see a whole number of occupations where you might think that technology is going to destroy jobs because it’s taking over tasks; and the reverse happens.

Several of the designers I worked with liked him, in as much as he gave them research to back them in their arguments with clients that the site should actually be usable.

It is still one of the high points of my career that I was part of a team that shipped an internet banking application that worked well in the then-current major browsers of IE 6 and Navigator 4, but also worked in Lynx and on a Palm Pilot browser.

People do kind of worship at Trump's feet. The actual anti-christ is going to have a high priest that performs miracles in his presence. Like magic tricks but more real. The anti-christ is also going to receive a mortal head wound and resurrect 3 days later.
