Some laws for protection do exist — eg requirement that sensitive data needs to be kept on systems that have been pen tested. But those laws are hardly ever followed and authorities have no real way to check if the 'protected' status of digital storage is actually maintained. What's worse is there are actually voices inside the government that are calling for an end on encryption stating that it encourages criminal activity.

An awesome beat'em up :)

100% agree. I'm not a big fan of apps being distributed through stores owned by big corporations.I had faith in Fdroid but sadly it hasn't taken off.

I also think app development requirements are too high. Just to compile your app and run the build process you need a very high end computer. I could never do it with my modest laptop and therefore gravitated towards web programming and more backend work. Thankfully I avoided all the pain of building apps and getting them approved by store owners. But I do have respect for people who have to deal with this bs.

It may sound too opinionated and may hurt some feeling but I don't like android at all. I think it sucks. But I have little choice. So I grin and bear.

That's my stance as well. Unless the website is completely broken or the devs force me to download the app by blocking features on the website I prefer the web.

With responsive design becoming mainstream I'm fine with using my browser for 90% of my internet work. In some cases like Google docs it's painful to use the web version so I just use the app.

EDIT: I wish they'd add a console to mobile web browsers though.

Yeah this is amazing. I'd love to see integration with raylib at some point, if possible that is.

Lua's small footprint is it's one big advantage in addition to its pleasent syntax but with tiny cc (which raylib supports when I last checked a few years ago) you can get a compact c runtime as well.

I haven't worked on a project with either of these frameworks but a couple of years back I was researching into some frameworks and was surprised to learn that I can use raylib on my phone with termux!

KDE is amazing. For an open-source project the desktop environment looks really slick. Not that any other desktop environments are particularly ugly but KDE can compete with the best commercially developed desktops.

For a moment though I thought that this story was about the launch of a new plasma TV 'big screen' and it got me really excited.

I think you have a point. It could be difficult to justify the cost of carbon capture based on sequestration alone. One of the reasons I think this might still work is that captured carbon can be used to create platform chemicals (various hydrocarbons) using the fischer tropsch process. Electrofuels are using direct air capture to generate fossil replacements.

Only requirement is energy and there too it isn't all that expensive to pull air in from the atmosphere or to seperate CO2 from adsorbent via low grade heat (70-100c)

So far into the future this method could allow us to continue produce critical hydrocarbon materials (used everywhere from plastics to pharamaceuticals) without having to depend upon concentrated and contested oil supplies.

More than energy efficiency its volumetric efficiency that's the issue. At the moment (to the best of my knowledge) kg of capturing materials capture tens of grams of CO2. Pulling it from air is not that energy intensive but finding materials that can actually filter out CO2 from that air is difficult. If breakthroughs are made in this area it will have industrial applications. Then it won't be just sequestering.

Of course the easier solution is to plant more trees and grasses but they grow very slowly and require valuable land. Still this approach is feasible in some uncultivable lands. Crops like cottongrass[1] can grow even in tundra climate and can be valuable source of both technically imp carbon via cellulose and a means to capture CO2. We don't have to make a choice. We can do both simultaneously.

I find it a bit funny. Robert Stirling invented the Stirling engine because steam engines were dangerous (at that time) and could explode.

Malone(and others apparently) took Stirling engines and filled it with compressed water as a working fluid with some decent efficiency!

The advantage, based on what I could gather from limited info available, was that these liquid engines could be run at lower temp differential making them great for low grade heat recovery.

The entire website is amazing! It should be archived.

Thanks for bringing this up. It seems they keep on updating it. The date on the article at the time of posting was 22 Dec 2025.

A few years ago I took his course on thermoelectricity and really liked his way of teaching. The videos were short and to the point and yet gave me all that I needed to know about the topic.

Here's the link in case anyone s interested

I was quite surprised too to learn how well terminal apps work on Android. Termux is amazing.

Rousseau was famous for saying that man is born free and is everywhere in chains. He advocated for self rule and formulation of laws by the people. Yet after 100s of years of democracy (thousands really) the corrupting influence of social norms has not really been remedied.

Inequalities still exist,corruption still happens and social institutions that were once liberating become oppressive over time.

His ideal of self governance has not been realised as most nation states have adopted a representative democracy. People don't really make the rules. They just handover the power to someone else who makes them on their behalf.

It's certainly right that Franklin believed in practicing virtue. He famously kept a log of his good and bad actions.

Yet there is another great philosopher that has had tremendous impact on American society whom the author has not mentioned. Emerson believed in transcending societal definition of virtue and vice and follow one's own inclinations. His ideas of self reliance resonated with American people and brought about a change in their thinking when they started to believe in themselves rather than looking to Europe for intellectual guidance.

I find it difficult to accept either Franklin's or Rousseau's view as they were more politically motivated—Rousseau wanted his social contract,Franklin worshiped Socrates but when it came to governence he kicked him aside to chose democracy,an idea that was popular at the time due to thinkers like Locke.

Emerson gave people true agency over their lives and inspired them to think critically and not sheepishly believe a thing to be good or bad. He was more revolutionary than Franklin (Self reliance was released around the time of civil war) and gave people courage to question institutional authority and he eventually became more impactful than Rousseau's collectivism.

I don't know. Content matters more to me. Many of the articles that I read have so little information density that I find it hard to justify spending time on them.I often use AI to summarise text for me and then lookup particular topics in detail if I like.

Skimming was pretty common before AI too. People used to read and share notes instead of entire texts. AI has just made it easier.

Reading long texts is not a problem for me if its engaging. But often I find they just go on and on without getting to the point. Especially news articles.They are the worst.

Your comment reminds me of apple's attempt to make sapphire screens. That didn't turn out so well.

I think what they have grown diamond on the transistor which then bonds to the substrate through a SIC interlayer.

From what I understand their idea seems to be that since most heating occurs at channels they act like hotspots and therefore it would be much better to drain away heat from them directly.

This is different from creating transistors on a diamond substrate.

It certainly is a great hobby. I'm not a physicist either but I keep reading papers and taking courses on YT about areas I'm interested in — Materials science,plasma, Electrostatics,fluids,thermodynamics etc.

Good thing is science doesn't change like tech. Once you learn something it's for life. No need to keep learning new frameworks/tools every year. It's stable and yet immensely flexible.

With AI research and studying has become a lot easier. Give it a try if you're interested.Now is a great time to start.

Apologies. I write everything in plain text on my mobile and just copy paste it to blogger/fb. Most platforms automatically create clickable links (hn also does that) but apparently blogger does not do it.

I like full links on the post because it makes it easier to backup. If I embed them in anchor tags they'd have to be parsed from the formatted web page or I'd have to store data as an html file. I don't want to do that.

md is a good alternative and slowly I'm migrating my files to GitHub.

Absolutely! Ozone is produced as a byproduct but I don't have any refrences at hand. More generally it can be said reactive oxygen species are produced as an intermediary that turn into several compounds as plasma is cooled.

Whatever gas you make bubbles from is going to be ionised(plasma is created during cavitation) and it's going to produce a cocktail of chemicals inside as it cools below ionisation temperature.

Many of these are shortlived eg oxygen reacts with hydrogen or nitrogen to form more stable compounds but some intermediaries can be stable and be detected.

The absolute max amount of nitric acid you can get for example is proportional to the amount of air dissolved in water. If you cavitate entire 1L of water max HNo3 you can get is about 20mg. Realistically it's not possible to cavitate such a large volume of water at once and there's a competition among reactants to form other products eg oxygen is going to used for hydrogen peroxide as well. Very sensitive instruments are used to detect these.

This is studied in sonochemistry —using bubbles to drive chemical reactions.Not enough for large scale production but small doses of chemicals — mostly radicals can be delivered by bubbles making it useful as a disinfectant.

I'm disagreeing that it's trivial to check for fusion because of low mass of gas inside the bubbles and suggesting that it's unlikely that fusion would ever happen in a bubble because temperatures required for fusion are way higher than bubble cavitation temperatures.

Do you have any ideas on how detection can be made in a bubble radius of say 100um?

In laser fusion experiments the pellet size is in mm range and it's completely filled with solid/liquid hydrogen to achive high particle density.Thats not possible in a bubble.

The thing is even for something as well studied as sonoluminescence there is no scientific consensus. Literature is all over the place when it comes to bubble gas temperature during cavitation.

Lots of arguments and debates are ongoing in the community. I think that's what happened with fusion story.

Very likely. The hot plasma generated would form oxides when it's cooled. I read a few papers a while back focussed around generating ammonia and other nitrogenous compounds. I can't find the link to the one I read but apparently other researchers are doing something simillar

https://arxiv.org/html/2505.23850v1

In air bubbles NOx would be likely but it would probably lead to nitric acid production after reacting with water. Here's a paper by NASA that pretty much confirms your intuition

https://ntrs.nasa.gov/api/citations/20050215681/downloads/20...

Researchers have reported neutron detection but these results have not been reproduced and some scientists have attributed this detection to 'noise'. Bubbles are tiny they have very small amount of gas in them so detecting that is not exactly straightforward... I think

for example a in a 1um radius bubble the total mass of gas would be ~ 10^-18kg.

Personally I doubt fusion occurs inside bubbles. Even if we take the highest reported temp 30000K that's way below what's required for fusion.

Also bubble literature is full of fantastic claims—one that comes to mind is assertion that pressures of around 10Gpa can be generated which seems highly improbable because that's likely to induce phase change in the fluid.

However it's quite possible that I'm wrong. Because bubble science keeps on throwing new surprises.

I first read about prof Kroemer when I was researching on semiconductor heterojunctions. Later on I learnt about his lemma and his quote always stayed with me

>The principal applications of any sufficiently new and innovative technology always have been – and will continue to be - applications created by that technology.

Would love to read about any interesting stories you may have about him.

I find AI to be mostly overrated but helpful in certain scenarios. It has helped me during my research & provides a different way to lookup for information as compared to traditional search engines.

But I don't find its generative capabilities to be all that impressive. It is generic and uninspired at least in text generation. I feel the same way about most new things that are emerging out of the tech scene since Blockchain. I dont even bother with tech news nowadays.

AIs adoption has been quite fast though. Unlike blockchain that never went mainstream AI has captured the casual user segment. It's being used everywhere from recruiting to emails. In offices and in schools. It's hyped alright but real people are using it.
