I think this kind of stuff is like reading tea leaves. Funny, but without prediction value.
LBNL had a solid state thermoacoustic resonator the size of a coin, which I read about but never saw it in the market. It was supposed to be able to extract heat from anywhere.
While I agree that it's very questionable that Nature would invite someone to write an obituary (or what have you) and then reject it, I fail to see what's so controversial about the text being overly technical. I work in Physics, and "[...] locus of solutions of sets of polynomial equations by combining the algebraic properties of the rings of polynomials with the geometric properties of this locus, known as a variety" is still an incredibly tough sentence to parse on the first pass. I cannot imagine how it would read for someone who is either unfamiliar (or only passingly familiar) with, for example, the concept of a ring; "algebraic properties of a ring of polynomials"? This just seems like a case of https://xkcd.com/2501/ , with a hint of arrogance in thinking everyone working in STEM must be as comfortable with abstract concepts of mathematics as mathematicians are.
Why the 100GB hard limit? If you can stream from disk you should be able to process infinite data sets if the operations allow it. If you need to do stuff like deduplication, then it will depend on how much RAM you have available.
hx-target="closest <your element here>" hx-swap="outerHTML swap:1s" hx-push-url="false"

That'll return whatever partial thing you want to return and replace <your element here> (with 1sec effect).
Could that have been solved by placing a tarp over the unit beforehand?
They went to digital releases because they wanted access to a large customer base. Buying physical music is a chore I certainly don't have time for, nor would I be able to listen to music from an LP or cassette in any of the scenarios I normally listen to music. Plus, LP and cassette audio quality is Very Bad, and LPs wear out.

Music was pirated before digital music was a thing, but it brought a way bigger market. The problem now is with how newer streaming services haven't figured out how to pay artists, or have been unwilling to do so. Although, perhaps the value of music has just changed with time.
But the screen consumes most of the charge in a modern phone anyway. The smaller the screen, the less battery capacity you need to get a sensible battery life. The CPU also matters, of course — that's one thing I like about my Pixel 4a, it lasts long even after 3 years because it uses a weak-ass SoC that nonetheless is perfectly capable for messaging and web browsing.
Python is slow, reee.

This is a major problem in scientific fields. Currently there are sort of "two tiers" of scientific programmers: ones who write the fast binary libraries and ones that use these from Python (until they encounter e.g. having to loop and they are SOL).

This is known as the two language problem. It arises from Python being slow to run and compiled languages being bad to write. Julia tries to solve this (but fails due to implementation details). Numba etc try to hack around it.

Pypy is sadly vaporware. The failure from the beginning was not supporting most popular (scientific) Python libraries. It nowadays kind of does, but is brittle and often hard to set up. And anyway Pypy is not very fast compared to e.g. V8 or SpiderMonkey.

Reee.
To me, the Pi 5 misses the point.

The original Raspberry Pi was $25 and ran Linux. All it needed was a random USB PSU to work. This made it suitable for a lot of random projects. Smart light switch? Get a Pi. Homebrew thermostat? Get a Pi. Want to show off a Beowulf cluster? Get a dozen Pis. The cost and size was less than a normal thermostat (or even a nicer light switch). The size and complexity was low.

Now, it's $80 for the 8GB version. It requires a lot more power, and increasingly, active cooling, and what-not. Once you toss that in, it's big, expensive, and clunky. It's usable as a desktop-replacement, but the flipside is that the cost, size, and weight is the same as getting a computer. You can find a much more capable SFF desktop from Dell Refurbished or eBay. It actually costs more than a basic Chromebook (running Linux), and the Chromebook brings a lot more.

Pi Zero is perhaps on the right track, at $15 (the non-wireless version is sold out everywhere), but unfortunately, requires a fistful dongles to make work, which makes it miss the mark.

The appeal is also largely reduced by how much the cost of computers and other devices has gone down. Why spend $80 computer on a Pi when a full-fledged Android tablet from Aliexpress, with case, screen, touch, and battery, sells for half of that?

(The answer, for now, is legacy hats and infrastructure, as well as open-source, but that won't last forever; at some point, an Aliexpress vendor will sell that $40 tablet with open-source infrastructure, documentation, and perhaps a few GPIO pins too).
Well… wow. That sucks. Why?? Couldn’t they have him pitching in on other projects or something? Seems a tough pill. Gosh. Is the money posit is able to make from its R products dropping or what? Would be super interesting to know the inside details on what’s going on with Posit now.

Looks like they have reached ISO9001 compliance as it seems every plane has the issue.
That looks like blogspam to me, rather than an actual source.
A building’s heat loss (the rate of energy needing to be re-added to maintain thermal equilibrium) increases with decreasing outside temperatures and decreases with better insulation.

A heat pump’s max output in heating mode decreases when the outside temperatures are low enough (whereas a gas boiler has a roughly constant max output and it’s quite inexpensive to size a wall-hung combi for 150K BTU/hr [44 kW] if needed).

Buildings that are fine on the coldest design day with a gas boiler may need more output than a heat pump can provide on that day.

Adding insulation can reduce this gap, which is why you’ll often find a heat pump project needs insulation, while a boiler replacement like-for-like would merely benefit from additional insulation.
The reason this approach is so much slower than some of the other 'fast' pythons out there that have come before is that they are making sure you don't have to rewrite a bunch of existing libraries.

That is the problem with all the fast python implementations that have come before. Yes, they're faster than 'normal' python in many benchmarks, but they don't support the entire current ecosystem. For example Instagram's python implementation is blazing fast for doing exactly what Instagram is using python for, but is probably completely useless for what I'm using python for.
Also note that one doesn't have to go 'all-in' on heat pumps, and there are dual fuel / hybrid systems available:

> A dual-fuel heat pump works in conjunction with a furnace. During the summer months, the heat pump works like a high-efficiency central air conditioner. In mild spring and fall weather, it provides cost- effective and efficient heat. As the temperatures drop in the winter months, the pump shuts off and lets your furnace take over.

* https://www.lennox.com/buyers-guide/guide-to-hvac/glossary/d...

* https://www.trane.com/residential/en/resources/glossary/dual...

More of a thing when heat pumps were more expensive and/or not as capable as they are now: going down to only 5C or -10C, whereas now units can go down to -25C.

They could also still be useful in places with less reliable power (rural? coasts?), as a heat pump need more electricity, whereas a furnace just needs to power a fan and an ignition system, so a small portable generator can handle the load (or it won't tax your battery system as much).
Entropy. Delta S = Delta Q / T. An efficient use of energy produces as little entropy as possible. Here the loss is Delta Q / 303 - Delta Q / 3043. T in Kelvin.
Taiwan won't be independent much longer. Xi literally told Biden this? China has only a few months to get this going, but will have a huge amount of consequences for doing so.

TSMC is rushing to build in europe and usa.

Looks like Russia is going to fail at taking Odessa and take control of one of the biggest sources of neon for chip fabs. China will require Australia in the near future. But will taiwan's invasion change this? Australia already knows about this relationship.

The challenge here is that there's nothing that will stop this inevitability. China hasn't seemingly figured out they are in a huge trap of their own making. Their inability to pull out of this trap means India will become the next asian super power. The China-India war will have to go hot.

Then again the exodus of Punjabs leaving this war is at world war levels of immigration.
I've mentioned this before and got downvoted because of course everyone is a web dev and knows what xyz random framework (name and version number in the title, nothing else) is.
of course, but most of us aren't working on products where a quality problem would kill hundreds of people. Having aircraft-level QA would be plain silly, you don't expect that level of quality from most other industry like eg guitar manufacturing, do you?
Are you certain that search is more important than chrome?

Sure search was their first product, but they have long since pivoted to being an ad company. And while yes, they can show ads along side search, the real cash cow is all the juicy data they can exclusively hoover up through Chrome to better target ads all across the web not just search.

JS also had the major advantage of being sandboxed by design, so they could work from there. Most of the technical legacy centered around syntax backwards compatibility, but it's all isolated - so much easier to optimize.

Python with it's C API basically gives you the keys to the kingdom on a machine code level. Modifying something that has an API to connect to essentially anything is not an easy proposition. Of course, it has the advantage that you can make Python faster by performance analysis and moving the expensive parts to optimized C code, if you have the resources.
We probably don't have the same definition of mediocrity then, the way I look at it is that if you go for a hike you're already in the top 25% which puts you way way way out of mediocrity. Most people haven't done anything more straining than walking up a couple of flights of stairs in their last 5 years

Again, nobody in the entire world prays for a mediocre life, a mediocre health, a mediocre salary, a mediocre partner. If you could put in the same amount of effort and get better results you'd accept on the spot. There is joy in things, no matter how good you are at them, but being mediocre at something certainly doesn't bring more than being average or good at it.
> You hold your hand to the exterior walls of your typical 2-3 bedroom terrace house (the most common type of home in the UK) in the winter and its just ice cold.

The opposite is now becoming more true: with heat waves that seem to occur more often, you want to keep the heat out and the cold in in the summer.
Those that remained weren't taking advantage of Unity features anyway.
> 1) heat pumps make much more sense when you don't burn things to power them. Solar PV, wind, hydro etc powering heat pumps mean you turn energy that is not heat into heat

A heat pump that is entirely powered by electricity generated from natural gas is most likely still more efficient than burning that gas to directly heat a house. Obviously though, using renewables is better.
It was three years ago but I got a quote for 10 boards at Aisler and it cost significantly less than 100€, possibly 50€ for all 10 boards.

Meanwhile the Chinese competitors always failes the DRC due to laughably bad tolerances. I'm talking about edge mounted through hole connectors, not some deeply buried via barely squeezed in.
If we could move from liquid helium to liquid nitrogen cooled magnets, then the cost of such machine (total cost, both capital and operational) will drop a lot. Countries deploying MRI machines today could increase coverage and lessen wait times. My relative recently waited 2 months for non urgent MRI (assigned by doctor). Some countries have it even worse.

And MRI which can be cooled with a conventional electric freezer would cost order of magnitude less, probably. Which mean it could be deployed even in the rural regions and underdeveloped countries, like some x-ray machine today (it is more complex tool of course, this was a metaphor).

So that's the gist of it, reducing the infrastructure costs significantly. And the interesting thing about diagnostic healthcare is that their potential market is a perfect circle of all humans on the planet. The maximum possible market, because we all get old, ill and die eventually. All need better diagnostics, but not all needs a new car or new computer or new gun, or new chat application.
do some of these bolts also carry the weight of the door?

what if the springs on the lower hinges (that are supposed to keep an upward pressure on the door, supporting its weight) are weaker than necessary or somehow failed and went unnoticed... would that put too much burden on the bolts and other fastening mechanisms and cause them to fail in turn over time?
Revealed preferences assumes that there are no confounding factors, no tyranny of small decisions, no information asymmetry and an unlimited selection of products that vary along every combination of features. It’s economic drivel, and serves only to dismiss opinions out of hand.
And? That’s still taking customers data and selling it
A modern natural gas furnace is upwards of 90% efficient. So you’re talking about building all this infrastructure (turbine generator, heat pump, etc) to capture the remaining 10% for electricity? How does that make any economic sense?

Additionally, heat pumps can already be purchased cheaply from the hardware store. These are closed systems with the refrigerant already inside. However, if you want a larger central air system then that costs a lot more because you need to hire licensed HVAC professionals to handle the construction and charging of the refrigerant loop.
More translation work for customers, perhaps, but reviewing is grinding work she has no interest in pursuing, and has the luxury of being in a position to do so.

It would be useful to allow the option for determinism (with its security downside) e.g. for people who want to assert that a directory contents hasn't changed? Or is there a simpler/standard way to get a hash of all content under a given directory? Something like fd | sort | xargs cat | md5sum, but including file names.
I'd buy OpenAI's claims if it were still a non-profit working for the public good. As a non-profit-turned-sleazy-get-rich-quick scheme, I do not.

And yes, that is a valid argument. The fair use test looks at:

1. the purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes;

2. the nature of the copyrighted work;

3. the amount and substantiality of the portion used in relation to the copyrighted work as a whole; and

4. the effect of the use upon the potential market for or value of the copyrighted work.

#1 flipped around when OpenAI turned evil. #2 is "everything." #3 is "all of it." #4 is "increasingly significant." At this point, OpenAI is batting 0/4.

the carnot limit for 2770°/0° is 1 - 273/3043 = 91%

the carnot limit for 30°/0° is 1 - 273/303 = 9.9%

so if your gas flame is really 2770° (which i doubt, the adiabatic flame temperature for methane in air is only 1963° and actual flames are even colder than that) you're wasting 90% of your exergy by diluting it down to 30°

also tho i do not want to go to your house if you heat it to 30°

Sure, for UNIX scripting, for everything else it is plainfully slow.

I know Python since version 1.6, and is my scripting language in UNIX like environments, during my time at CERN, I was one of the CMT build infrastructure build engineer on the ATLAS team.

It was never been the language I would reach for when not doing OS scripting, and usually when a GNU/Linux GUI application happens to be slow as mollasses, it has been written in Python.

other than pressure differential...what about the weight of the plug door itself ... do the bolts support that weight?

or if some other mechanism like the springs on hinges below grew weaker over time .. would that in turn put too much weight on the bolts?

They don't want to service the laptop even if you don't have warranty.

I have a Mac from 2016, probably had a minor water event, water spilled on table and slightly touched the chasis. I don't remember anything significant. The battery lasts 20 minutes in 2021, I go and ask them to replace it and they refuse because of "water damage" and warn that the machine can fry at any moment. The laptop is still running fine daily in 2024.

They can only "fix it" by charging more than a price of Macbook Air M1, they do not want to replace the battery but the whole board.

Show HN: Self-hosted free geoip service
Hi HN,

I wanted to share this simple python app that you can host using App engine and get a free geoip service. It's pretty easy to limit it to the free quota and run without costs.

You can't query for a specific IP address but it becomes super useful if you can make that request from the user's side (browser, app, etc).

It only has access to lat, long, city, country, ip address but I find those to be the most useful data points.

Hope this helps.
I don't think the Small-C compiler was all that popular with professionals (or even hobbyists). It was incomplete, slow and produced (on the Z80) poor code.

C was indeed not ideal for 8 bitter (hence the astonishment around this topic). CP/M istself was written in PL/0 (I suppose with a sprinkle of assembler). Macro assemblers were popular then for shrink-wrap software. Custom software was often done in BASIC.

Professionals used cross compilers (or cross assemblers) when they had a chance. Microsoft BASIC e.g. was developed on a PDP-10.
> Practice still mattered: It accounted for 26 percent of the difference between good violinists and the less accomplished students. But the original study claimed that practice accounted for 48 percent of the difference.

This is very different from "10k-hour rule confirmed".

The study concludes that practice is positive, but it is a small part of being the best, practicing a lot won't make much of a difference to achieving elite status, although it is probably a requirement for it. The study also points out that the top players actually had practiced less than the average of good players.

And this is for violin playing (plus another meta-analysis on sports). While the 10k-hour rule is most often associated to Bill Gates, and technical, academic or business success (at least in HN circles). Very different domains where physical dexterity matters little and learning processes have nothing to do with internalizing complex movement.

The numbers discussed in the study are roughly around the 10k-hour ballpark (practice before the age of 18). But again, there's nothing indicating that this generalizes to anything other than violin playing. I think it is fairly obvious that different disciplines take different time to master, although I haven't looked into the studies about it.
i agree that the other languages gained a lot for sure

maybe i should have said that up front!

except maybe common lisp; all the implementations i know are interpreted or aot-compiled (sometimes an expression at a time, like sbcl), but maybe there's a jit-compiled one, and i bet it's great

probably with enough work python could gain a similar amount. it's possible that work might get done. but it seems likely that it'll have to give up things like reference-counting, as smalltalk did (which most of the other languages never had)
