I believe that at one point there was a term in a licence agreement from one of the companies involved that basically prohibited it ever being ported to anything else... but that's long ago. I wrote about the Moonshot effort recently:

https://www.theregister.com/2025/04/01/risc_os_open_moonshot...

... And I'm still talking with ROOL about the directions they're examining. The restriction may no longer hold true.

Every single one of the above is true.

The self-healing capacity of ordinary Portland cement is very limited, but it's there, and you can easily find literature backing this fact up, e.g.[1]

You can also trivially look up strength figures of OPC concrete vs Roman concrete. Modern concrete is overwhelmingly stronger, and can be made even stronger where it needs to be.

As for being subjected to incomparably higher stress... are you really claiming that Roman architecture was ever subject to anything comparable to thousands of multi-ton vehicles driving at dozens of kilometers per hour? Or to anything comparable to the weight of a high-rise building? And don't forget that it made heavy use of arches, which isn't necessary anymore thanks precisely to the strength of modern concrete.

We also know what the composition of Roman concrete was, and there's literally thousands of publications on self-healing variants of concrete. You can buy most of them. They're just not a priority for most applications.

People really need to stop romanticising Roman concrete. It was incredible, sure. But it's got nothing on modern cementituous material science.

the pricing for lower income countrys is proof of a kind of desperation in there atempts to retain relevancy, the ultra high pricing in saudi/swiss is further proof, as it ensures that the wealthy will never hear the help discussing the same storys, the last proof is the missing countrys from the list, kind of like the mean spirited weather reporting in England, that greys out Ireland proper.

My experience:

- Dokku - too much shell scripting and you forget all the commands you typed after 1 year.

- Dokploy - you need to install it on your host. So it makes it difficult to switch to a bigger host.

So now I am actively developing a new platform which solves all this - DollarDeploy.

It makes it easy to deploy app from GitHub repo to the server of your choice, and automatically generate HTTPs cert, manage hosts, backups etc for $1/app/month.

Would be nice if you give it a try and provide feedback!

This is really cool! Building a browser engine from scratch is no small feat, especially when handling complex CSS features like calc(), var(), and percentage units. It’s a great way to learn the inner workings of the web.

Curious about your approach to the networking stack. Are you planning to support more protocols like HTTPS or WebSockets in the future, or is the focus more on keeping this lightweight and minimal for now?

I love the language of this article :-)... it may be florid, but that's quintessentially human.

About the substance, I agree that there are fair grounds for concern, and it's not just about mathematics.

The best case scenario is rejection and prohibition of uses of AI that fundamentally threaten human autonomy. It is theoretically possible to do so, but since capital and power are pro-AI[^1], getting there requires a social revolution that upends the current world order. Even if one were to happen, the results wouldn't last for too long. Unless said revolution were so utterly radical that would set us in a return trajectory to the middle ages (I have something of the sort published somewhere, check my profile!).

I'm an optimist when it comes to the enabling power of AI for a select few. But I'm a pessimist otherwise: if the richest nation on Earth can't educate its citizens, what hope is there that humans will be able to supervise and control AI for long? Given our current trajectory, if nothing changes, we are set for civilization catastrophe.

Flash circa 4-7 era had a really nice scripting environment for ActionScript where you could select instructions via a drop-down and edit fields for each instruction (with the fields being of dynamic input types). I've never seen something like these days, but for a 12 year old me it was really fun and simple to use. It also came with an integrated offline manual.

Maybe you could try something like that?

Author of the "Osaifu-Keitai-Google-Pixel" article here.

There's a big chance that Apple does not eat the cost for Osaifu-Keitai actually, as they may have a sweet-heart deal, hinted by an article from watch.impress [1], which I found a very long time ago via Twitter.

So the fee is either waived by FeliCa networks, covered by Japanese Carriers, and (as an educated guess) paid only upon enrollment of the first FeliCa-compatible card to device.

I think it would be naive to believe that Apple, of all companies, would be the one willing to pay a couple of cents per device in order to offer a feature that, at best, only a single digit percentage of their users would use.

Yes, the Glulam alternative tends to be a bit more expensive for some applications, but I am surprised that it is 5x more expensive than the steel solution. The reference I have (in Europe at least) is that the cost of Glulam is currently about 350 €/m³. Steel is quite more expensive, but of course, the profiles are slender, so less material is used.

I’d very much like to read about Blade, but seems like they have literally no documentation in text format, not even a basic introduction. Every link on the GitHub page goes to YouTube.

Project authors, please don’t do this. It’s impossible to get a two-minute overview from a video. Browsing through tutorials and documentation is much more efficient.

If you really have never written anything about the project except conference slides, then at least put up that deck in addition to the YouTube link. Clicking through slides is not great, but it’s still a better browsing experience than seeking at random in a video.

Although sarcastic there is something here. I was also thinking about ethical social media.

YouTube is the only place where timeline could be turned off when search history is off and guess what happened I am no longer addicted to YouTube.

Just imagine there is a way for users to opt out of algorithmic feeds in the other social media. Would Instagram still remain addictive? Would Facebook still remain addictive? I think this must be one day of the universal fundamental rights of a human in digital space. They are using our data to do all the crappy things they are doing. Imagine the problems this one small feature could resolve in this world. Remember we are here to improve ourselves spiritually. Using social media and it's algorithmic feeds we are most likely to transcend the baddest quality we have or are born with. So this is an important revolution to happen

The camera didn't kill painting. Neither the bicycle nor the motor-car killed running. There are already subfields of mathematics where it's believed that all the interesting discoveries have been found and no-one is looking except for the occasional amateur - and other subfields where to even have a hope of doing cutting edge research you would need to both do multiple years of postgraduate study and then get accepted onto one of a small number of close-knit teams that are pushing that cutting edge on an industrial scale.

So I don't see any reason to worry about the impact of AI. Unlike most fields with AI worries, mathematical research isn't even a significant employment area, and people with jobs doing it could almost certainly be doing something else for more money.

«“The Germans are telling us: we will be very pragmatic on the issue of nuclear power,” said a senior French diplomat involved in the talks. This meant that “all the biases against nuclear power, which still remain here and there in EU legislation, will be removed.” “This will be a sea-change policy shift,” said a German official.»

Will it really?

https://www.pv-magazine.com/wp-content/uploads/2024/10/Level... is a little unusual, it shows the cheapest nuclear power to be as cheap as the most expensive PV+battery. Still, it's difficult for me to see how this policy change will really change anything.

A real change would require a commitment against market-based production/sale of electricity, e.g. a quota such that power generators using PV/batteries were allowed to produce at most x% of the power in the EO.

HDDs use much simpler electronics than SSDs. The controller in a hard drive mostly just moves the read/write head and spins the motor. It doesn’t need to do much processing. These chips are built on older manufacturing processes that are cheaper and less energy intensive.

SSDs though need a fast processor to manage the flash memory for wear leveling, error correction, and keeping track of where everything is written etc. This requires more advanced chips, built on newer process nodes, which take a lot more energy and resources to make.

And SSDs also need extra chips like DRAM and obviously the flash memory itself.

You quote a PV-lobbying firm as your source, what do you expect?

Also LCOE is just not adequate to compare these two, as you have additional storage and transmission costs for intermittent, weather-dependent sources, whereas most nuclear power plants can be online providing full capacity more than 90% of the time.

LCOE does not account for that.

This IEA report uses a metric that includes those system costs (value-adjusted LCOE, VALCOE) and it shows nuclear energy is definitely competitive. Especially if managed well and power plants aren't prematurely shut down due to political reasons, like they were in Germany.

SRS is wonderful. The improvements in the linked article are real and laudable.

But they are comparatively narrow and technical compared to the improvements that need to be made in usability and scalability (of content dissemination and navigation).

Shameless: I am working on a FOSS SRS platform / toolkit that I believe can take some substantive steps forward here. Can read some at http://patched.network, or poke around http://github.com/patched-network/vue-skuilder

> Every browser sends an Accept-Language header. It tells you what language the user prefers, not based on location, not based on IP, based on their OS or browser config. And yes, users can tweak it if they care enough.

This is also a broken assumption.

First, Accept-Language is an ordered list, and most daily-multilingual people don't have an absolute order of preference, and more a topical list of preferences.

If I read an English news site that has a translated French version, it doesn't matter if I'm most proficient in French, I'll want the English version.

Then, as an affect of the first point, users will specify their most practical language, not some actual preference. For instance local non-English sites tend to do less shenanigans than international English ones, so having one's language set as English only will force English display for the former, with few impact on most other sites.

A French site ignoring all preferences and just pushing the French version by default actually helps in that case.

If anything, I just wish site owners stopped trying to be cute or clever and just had a very obvious and quick interface to switch to other versions. Wikipedia does it decently well for instance.
by donatj | 2025-05-19 11:09:27+00:00
I have told the story here before, but I built a neat little system to parse Accept-Language weighing the users priorities and using the closest thing we have on offer to the users preferences. As an example, we have a Brazilian Portuguese translation but not Portugal Portuguese, so we would offer the prior to users requesting the latter for instance unless they had a lower priority but more exact match.

From my technical standpoint it worked really well and the code was very slick. It was a lot of fun to build.

From a user standpoint most of our users really just wanted English regardless of their Accept-Language header. They had the option to change it in the footer but this apparently wasn't obvious enough.

We just ask now, and our users are happier.
by binarymax | 2025-05-19 11:09:50+00:00
Timely. I’m working on this right now for a product and have everything in place using the accept-language header and then adding a url param.

I’m currently agonizing about how to let the user change their language, because I want to respect locale as well (es-MX vs es-ES for example). And I haven’t found a good UX pattern for changing language+locale. I’ll likely just implement a big list that the user can select, and have the current language be a link that they can click to change via a modal.

> Flashing your wealth on social media or being a high profile executive is dangerous, crypto-ties or not.

Given the finite quantity that many cryptocurrencies can create, I'm curious if another 'attack' will become popular at one point: destruction.

If only x units / tokens and be generated, if you can destroy or otherwise make inaccessible some quantity, then the ones you already own should become more valuable. So perhaps in the future we'll find the kidnappers change from demanding a transfer to demanding destruction, so the perpetrator's own holdings grow in value.

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

> established in 1996 ... The Long Now Foundation hopes to "creatively foster responsibility" in the framework of the next 10,000 years. In a manner somewhat similar to the Holocene calendar, the foundation uses 5-digit dates to address the Year 10,000 problem[2] (e.g., by writing the current year "02025" rather than "2025"). The organization's logo is X, a capital X with an overline, a representation of 10,000 in Roman numerals.

You're probably right about this. In the short to medium term, I expect that the Rust and C++ sub-ecosystems will be making different sets of choices. I don't know of any major C++ game or game-adjacent project adopting, say, Dawn for their RHI (render hardware interface) to buy into WebGPU. In the longer term, I expect the ecosystems to start blending together more, especially as C++/Rust interop improves (it's pretty janky now).

Good. If Germany wants to do its own thing, then so be it, but they shouldn't be allowed to block / disincentivize other EU members from using nuclear power.

If we want to incentivize "clean" tech, we should go by an objective metric, such as co2 emissions per kilowatt-hour (where nuclear power is even less emitting than PV/Wind over its total lifecycle)

how easily any of these systems can be altered to meet an individual or group’s agenda.

And this is also where you need to think about whether your data model is going to be dependent on AWS-specific features. Ever want the freedom to migrate off of AWS? That is going to be harder if your multi-tenancy has AIM as a dependency.

Be wary of any training information from cloud providers that encourages you to implement complex solutions blending multiple cloud features. They are training you to adopt vendor lock-in.

The CRA literally excludes free software developers from the obligations. Because if you're doing something for free you should have no obligations either. Instead, the obligations fall on commercial users of free software. Turns out regulations are sensible sometimes. Who knew.

However, this only happened because free software developers made an uproar about the act while it was a bill and was missing this provision. In a previous proposed version of the act, free software developers would have been liable for security vulnerabilities. So stay connected with politics!

If over 100 ug/m3 for 2 minutes, turn on, if under 10 for 10, turn off. If someone's cooking, there is a very predictable spike that peaks in the low hundreds and then decays (super-) exponentially. It was surprising to see how long it takes to get back to ambient. I think you'd have to cook a steak with the stove extractor off to hit 1000 and our hard-wired smoke alarm would definitely be going off. I have no idea how absolutely accurate the SEN55 is, but the background level is usually below 5. I don't live in a particularly polluted place, so that seems reasonable. NOx is almost always zero.

>(1) completely insignificant wrt to the whole user base and

At any one time, there's got to be tens of millions of people accessing Google from a country which has a primary language unknown to the traveller. Even if this number is insignificant compared to Google's full user base, the cost for Google to service 20-30mn people with a feature is presumably lower than their annual ad revenues across 20-30mn people.

That's just the standard Accept-Language header, not unique to Safari or macOS at all. It's up to the server to interpret and respond to the header, and they mostly don't do what gp wants, i.e. they usually serve the translated language with a higher q rather than the original language even if it's in the list (and it's mostly ignored anyway in favor of geoip/manual region/language picker).

All free (as in beer) work on software is voluntary. You do not need, and should not have, someone breathing down your neck to make you do it the way they want. However, that person is free to decide to allocate additional effort to work on the software themselves - even forking yours. They're also free to decide how much open source software they want to use, and which.

This is something I used to misunderstand too. That open source was something where there were a fixed set of projects available, one or two for each purpose, and if you wanted a change, you contributed that change and they take it. In reality, it's where everyone has their own project that does the thing they want. Most are written by one person or by tight-knit groups. Drive-by contributions often cost as much for the developers to process as just doing the contribution themselves. If you don't like how some software works, you have the right to write your own software using the existing software as a starting point - you do not have a right to edit the existing project. These are the same rights the UN has.

Well, I disagree. Light literally can't move in a direction that makes it further from the singularity once inside the event horizon. I don't see what space being flat or not locally has to do with that. Check https://en.wikipedia.org/wiki/Event_horizon#/media/File:BH-n... for an example.

If your head is further from the singularity than your feet then you can't see them.

>sternness

I really enjoy observing this and other changes in social tone visible through the ages in archaic videos .. One of my favourite idle pasttimes is to watch videos on Youtube of digitized film from a bygone era, especially of cities I've lived in, or visited and with which I am familiar.

For some reason it is just so interesting, for example, to visit the streets of Vienna from 100+ years ago, and see how folks were living back then. So many well-dressed Viennese, looking sternly at the camera, or merely walking in a steady plod along streets I, too, in the modern era, enjoy.

Vienna is particularly interesting because it has a long history with film, and some of them go back to before the widespread adoption of automobiles. It struck me just how easily we overlook the fact that Vienna was built for walking, originally, and all the crazy car life that the city suffers now was grafted on top of routes originally designed to be navigable by foot - or hoof.

Just take a look at Vienna, from 1896:

https://www.youtube.com/watch?v=3aPvmD6ktZs

.. to Vienna, 1926:

https://www.youtube.com/watch?v=FGbTkQX6R0Q

.. pre-war Vienna (30's):

https://www.youtube.com/watch?v=ZA9dHEKD-vM https://www.youtube.com/watch?v=QITjWb29JZ8

.. Vienna, 1939:

https://www.youtube.com/watch?v=w96umMf9r3E

.. post-war Vienna:

https://www.youtube.com/watch?v=q2VbXdrFXB8

.. to Vienna, 1964:

https://www.youtube.com/watch?v=P0WCigqJ_wU

.. and lastly, Vienna in the 80's:

https://www.youtube.com/watch?v=WttS-PP-r4o

Its just so interesting to see how the city has evolved over the century, but also very interesting to see how it hasn't changed much at all, too!

These days I walk many of the streets depicted in these videos, and having binge-watched all the videos I can find on the subject, it has given me a much deeper appreciation of the trials this city has weathered.

(I've got another set of videos for Los Angeles, another city in which I've lived and loved, and it too is very intriguing to see the city evolve over time .. but I'm yet to find a film as old as 1896 for the region, strangely enough..)
