Thanks. I had first created the post some 2 days ago and it had gone dead. So when I booted up Hackernews and saw that I got additional karma. I thought that some of my old comments may have gotten upvoted and when I found none. I saw submissions and found that my project got quite a feedback/upvote in submission & it even has made to the front page of Hackernews.

I got quite a bit happy so I decided to enjoy privately for a while haha.

So I really appreciate your and everyone else's kinds words. Took time to read each and everyone in here.

Regarding the nitpick. I agree. I will see what I can do regarding this and probably play around with some more queries to see if I can fix this issue as this is the most common issue I got people talking about here so definitely gonna fix that right now.

Have a nice day! Glad you enjoyed it :)

Really? I have yet to use a single Slack-alike with search that actually works - including Slack, Teams and Mattermost. I mean they "work" in that the search results happen to include your terms too, but they give you the actual relevant message only about 10% of the time.

Rocket Chat does look nice! I quite liked Mattermost except for the mobile app being trash. How is the Rocket Chat mobile app?

It does. However, the hotter the water becomes, the less effective the heatpump becomes. With anything beyond 60C becoming very inefficient.

With hot water tanks, they are unfortunately pretty badly insulated as well, with some of them loosing heat very quickly. Depending on how you plan on using that water, you also have to make sure the temperature never dips below ~60C to avoid legionella from spreading.

I actually think that heating your home slighly higher than you‘d usually do is the simplest and most effective approach, assuming it is properly insulated. Just rise the target temp for 1-2C when the energy is cheap and reset it once it isn‘t. Probably not as efficient, but extremely simple to implement.

Qt means C++. I'll take Typescript over C++ for a GUI task any day.

Qt is also pretty memory-hungry; maybe rich declarative (QML) skinnable adaptable UIs with full a11y support, etc just require some RAM no matter what. And it also looks a wee bit "non-native" to purists, except on Windows, where the art of uniform native look is lost.

Also, if you ever plan extensions / plugin support, you already basically have it built-in.

Yes, a Qt-based program may be wonderfully responsive. But an Electron-based app can be wonderfully responsive, too. And both can feel sluggish, even on great hardware. It all depends on a right architecture, on not doing any (not even "guaranteed fast") I/O in the GUI thread, mostly. This takes a bit of skill and, most importantly, consideration; both are in short supply, as usual.

The biggest problem with Electron apps is their size. Tauri, which relies on the system-provided web view component, is the reasonable way.

Isn't this proposal closely matching with the approach OpenSpec is taking? (Possibly other SDD tool kits, I'm just familiar with this one). I spend way more time in making my spec artifacts (proposal, design, spec, tasks) than I do in code review. During generation of each of these artifacts the code is referenced and surfaces at least some of the issues which are purely architecture based.

Why, I don't get it. You don't think there are extremists or far-right nationalists in Israel? The National Religious Party–Religious Zionism is part of the government. The Likud charter is clear. If you have given a serious thought to the issue, you must have wondered what their attitude would be towards an end to the expansion of Israel.

Great app, pleased to be in the top 0.38%, but it appears that does not translate to a top 100 spot by an order of magnitude.

It would be nice to have some readership stats, too.

I've been wondering whether Webcam-based eyetracking software could be used to calculate via triangulation/trilateration which word one is reading on the screen.

Then words could be color-coded by impact.

> Does heating water in a boiler work well with a heat pump?

Sure, heat pump hot water tanks are a thing. Air-to-water heat pumps are less efficient than air-to-air as they need to reach higher target temperatures, but it will be more efficient that straight resistive heating by a factor of 2 at low input temperatures, and 3+-ish at high summer temps.

The primary concern would be the quality of the tank’s insulation. I would hope HPHWTs are good on that but…

Analysis: Wind power has saved UK consumers over £100 billion since 2010 – new study

https://www.ucl.ac.uk/news/2025/oct/analysis-wind-power-has-...

The interesting part is that 130 Billion of the savings were in reduced gas prices as it reduced demand, particularly in winter, and freed up gas storage.

And this is depsite an effective ban on onshire wind in England from June 2015.

Getting good video ideas has been the most important factor to my success.

To get new ideas, I started monitoring competitor channels every week, manually.

I got lots of good ideas that became viral videos. But the monitoring process is very tedious.

I built a tool to automate the process, for myself. Then I decided to make the tool available to others. This is ViralOutlier.

If you have question about the tool, reply to this comment.

10x is very very optimistic. Practically it would be more.

Even if you assume launch cost = zero its most expensive and less practical.

And the moon is even worse. Still you can assume launch cost = zero. But energy is one part, to actually reliably land on the moon with your whole infrastructure. Connecting all that infrastucture up with power and everything else.

Your basically doing a gigantic civil engineering project all with only roboitcs, while we can't even do a civil engineering project on earths with only robots.

And if your going moon, nuclear is clearly the better option then solar towers. And if you go nuclear anyway, just do it on earth.

WTF. If you really feel that way then stop using AI. Either you are building confidence or you aren’t.

Now, step back and do some serious introspection. First, look around. Odds are you are surrounded by imposters, irrespective of AI. Identify who the imposters are and isolate yourself from them. Secondly, solve hard problems. Confidence comes from learning. If you cannot perform without AI then your learning is low.

At the end of the day you provide solutions to problems. If you cannot do that almost instantly in your mind, forming a vision, you are less valuable than someone who can.
by bonoboTP | 2026-02-03 09:03:29+00:00
Yes but in my experience this sometimes works great, other times you paint yourself in a corner and the sun total is that you still have to learn the thing, just the initial ram is less steep. For example I build my self a nice pipeline for converting jpegs on disk to h264 on disk via zero-copy nvjpeg to nvenc, with python bindings but have been pulling out my hair over bframe ordering and weird delays in playback etc. Nothing u solvable but I had to learn a great deal and when we were in the weeds, Opus was suggesting stupid hack quick fixes that made a whack a mole with the tests. In the end I had to lead e Pugh and read enough to be able to ask it with the right vocabulary to make it work. Similarly with entering many novel areas. Initially I get a rush because it "just works" but it really only works for the median case initially and it's up to you to even know what to test. And AIs can be quite dismissive of edge cases like saying this will not happen in most cases so we can skip it etc.

Unfortunately, someone else had this idea before you.

Arithmetic operations with saturation for integers, either unsigned saturation or signed saturation, have been introduced in personal computers since Intel Pentium MMX (launched in January 1997). A few other CPUs and DSPs had such operations much earlier.

"Saturation" means that the highest representable number, e.g. 0xFFFFFFFF, is interpreted as positive infinity and all operations where it appears as an operand are defined accordingly.

While whatever CPU you have in your computer or smartphone certainly supports arithmetic with integer infinities, such operations are not available in the high-level programming languages. So in order to use them, you have to use assembly language, inline assembly language in a high-level language or compiler intrinsics that give access to the corresponding machine instructions.

Just to make it explicit, I (author) did not downvoted you.

Both me and sebst (co-author) tried to answer everybody and did so politely.

We respect other opinions and Stelvio (as any other thing) might and is not for everybody.

Regarding your question. Well, it depends on the size of the project. Small enough you can do anything fast. I'm working on bigger mostly serverless system on AWS and it did take lot of time to to setup everything with CDK, certainly days.

I believe it would be faster with stelvio as it offers higher level abstractions than CDK - Stelvio was born out of my frustraction with CDK, I was doing lot of things again and again, waiting long for deployments etc.

If someone is happy with CDK, then they should use CDK, it's good too, even for me much better than CF or Terraform.

But if you feel things could be even less cumbersome, with less code and faster, maybe you could give Stelvio a try.

We're not claiming we'll do everything for everybody, we have our opinions and Stelvio is opinionated - shamefully focusing on (app) developers rather than on infrastracture focused people. https://stelvio.dev/blog/why-i-am-building-stelvio/

Thank you for your comment and wish you a good day.

Qt is still used, but I think part of the reason it is less used is that C++ isn't always the right language anymore for building GUI application.

That’s actually why we're working on Slint (https://slint.dev): It's a cross-platform native UI toolkit where the UI layer is decoupled from the application language, so you can use Rust, JavaScript, Python, etc. for the logic depending on what fits the project better.

Can't speak for the benefits of https://nono.sh/ since I haven't used it, but a downside of using docker for this is that it gets complicated if you want the agent to be allowed to do docker stuff without giving it dangerous permissions. I have a Vagrant setup inspired by this blogpost https://blog.emilburzo.com/2026/01/running-claude-code-dange..., but a bug in VirtualBox is making one core run at 100% the entire time so I haven't used it much.

That's the whole point of this, no? Heat pumps can't heat up a large amount of water quickly (like resistive heating can). So if you have a solar peak at noon, where either yourself are producing cheap solar, or there's cheap solar on the grid in general, then you want to use that cheap energy to store heat for later use (like showers in the evening/morning).

So the way I see it, is that this material should be able to quickly store heat with the using the low temperatures that heat pumps provide, and be able to store it with minimal losses until it is needed.

PlantingSpace | Full-time | Remote (EU time zone) + Quarterly Meet-ups | https://planting.space

We’re building an AI system for analysts and scientists, based on a fundamentally new approach to reasoning and knowledge representation. Our approach differs from LLMs in that we compose algorithms symbolically to represent complex knowledge, and perform probabilistic computations. This enables the AI-driven application of statistical models to different problems, while providing the user with a verifiable reasoning path, and an assessment of the uncertainty in each answer. We are developing applications for analysis and research in domains such as Finance, Strategy Consulting, Engineering, and more.

This is a chance to shape a new approach to knowledge representation from the ground up, working alongside a collaborative team driven to solve hard problems.

We’re hiring for the following openings:

* Product Software Engineering (Quantitative Modeling)

* Bayesian Software Engineering

* Program Synthesis Engineering

* Technical Project Manager

* Finance Manager - Corporate & Accounting

Electricity doesn't travel continents the way shipping containers do. So it's not like anyone wants to build a wind farm and wonders where in the world they are going to place it. Plus if you are a major single customer (eg datacenter, factory), you need reliable energy, so would be odd to build a wind farm. As far as I am aware wind farms only makes sense when you sell to the grid, and where there is an alternative on demand source of energy to take over the weeks there is no wind.

Just as an example: I learn languages using Anki, and I always do it the same way: I use decks that

* exclusively quiz entire sentences

* introduce around 500 new words (a nice mix of nouns, verbs and adjectives)

* use a wide variety of grammatical constructs (including all conjugations of the new verbs),

* and that have audio of a native speaker reading the entire sentence after I "flip" the card

Such a deck needs to be thoroughly designed, and while I could choose the new words and then write software to make sure they are all used equally in sentences and no conjugations are missing, I actually can't easily make sure they are correct and I can't record the audio of the text.

So nothing to do with it using the most popular web stack, meaning the largest pool of potential contributors to the editor or extensions??? What about other cross platform frameworks that also allowed that??? (and of course it's not any platform, just 3 desktop ones where VSc runs)

I'm not even sure what you're arguing at this point.

Are you arguing that Electron helped VSCode win or what? Because Electron being able to use a popular web stack is also a benefit.

What is your point?

Because ARM lacks some of the device auto-discovery features that amd64 provides for free, unless you're lucky and use a device with ACPI+DSDTs on ARM. You need a special build for the hardware, but you don't need to alter the source code.

Custom kernels also exist for amd64 devices, often including workarounds and patches that are not in mainline to improve performance or compatibility.

As a vendor, that requires practically zero extra effort.

https://wiki.postmarketos.org/wiki/Devices has a list of devices that run either mainline or almost-mainline Linux. Only the "downstream" devices require vendor Linux kernels. Of course, hardware support is partial for most of these devices because vendors haven't contributed proper upstreamable drivers and volunteers haven't had the time to write them yet, but it's not like every ARM device needs a special kernel fork, that's just something ARM vendors do out of laziness.

I have two heat pump water tanks, one Rheem and one AO Smith (our local utility heavily-subsidizes these, with a net-cost less than a standard tank water heater).

They both are rated for annual kWH usage less than the US EPA yellow label can display (for their category of tanked water heaters, i.e. competing mostly with resistive heating models).

Annually water heating is about 3% of my energy consumption.

Galloway and Swisher have been speculating about this (as well as a Tesla roll up) for a while. It makes tonnes of sense from Musk's perspective- he's got this behemoth monopoly that'll be worth a trillion on the stock market, meanwhile he's got xAI and Twitter which are both sub-scale money losers. It's easiest way to bail out his bad bets (and keep his investors sweet). The only question is whether eventually Tesla joins the party, it makes the most sense for xAI and Tesla to be joined, but I just don't see how that can happen. The benefit of xAI and x.com is that they were private so there weren't meme stock valuations to compete with, the investors would take a resonable payout know, safe in the knowledge SpaceX will IPO to a meme stock valuation. Tesla's valuation has to return to earth before SpaceX can bail it out and by that point it'll be like catching a falling knife.

Where did you get that sweet RedHat money? I feel like I'm missing out, I'm happily using systemd, where are my RedHatBucks!

Seriously, I would not ever go back to a house of cards of bash and shell scripts of an init system. systemd solves actual problems and gets shit done, with a level of consistency that cannot be achieved by LEGO-like wet-dreams of UNIX worshippers. My favorite example is systemd-resolve and systemd-network that actually communicate together to indicate which DNS server is available on which network interface and with which search domains, to gasp do proper DNS routing.

Am I happy with all of systemd? Not always, it has a tendency to break networking after an upgrade with reexec. I'm still not convinced about homed. But oh my, you don't have to look further than actually solving problems to explain its success.

Yeah one of my colleagues has a preheat which can be triggered manually and via automation. They also have a preheat loop which cycles hot water through the entire piping as the boiler is on an edge, so it takes ages for hot water to reach the far bathroom.

The plan seems to be for lots and lots of smaller satellites.

For inferencing it can work well. One satellite could contain a handful of CPUs and do batch inferencing of even very large models, perhaps in the beginning at low speeds. Currently most AI workloads are interactive but I can't see that staying true for long, as things improve and they can be trusted to work independently for longer it makes more sense to just queue stuff up and not worry about exactly how high your TTFT is.

For training I don't see it today. In future maybe. But then, most AI workloads in future should be inferencing not training anyway.

Owner of the thirty-five employees company wants long term income and sort of security. They usually do not want huge peek in short term followed by death. They are also less comfortable with strategy that has 95% chance of destroying the company and 0.5% chance is earning a lot with 5% in between.

Outside investors are the exact opposite.

Also, smaller owners do not have that billionaire mindset of "any unethical or illegal action goes". It is not like they would be saints, but there is range of personalities and value systems among them. Billionaire became billionaires because not caring about any of that gives them advantage.
