This article focuses on the B2B HVAC sector, noting that the global smart thermostat market is projected to reach USD 6.8 billion by 2028. It emphasizes that automation and optimization features have become core competitive advantages for B2B clients (such as OEMs and distributors). Taking OWON’s PCT523 Wi-Fi Thermostat as an example, it introduces its technical solutions including remote sensor integration, 7-day programmable scheduling, energy usage reports, and cloud connectivity—these can help clients cut 10-15% of annual heating and cooling costs, enable large-scale multi-site management, and support custom firmware, branding, and BMS platform integration. The article also mentions the product’s applications in multi-family housing and commercial buildings, as well as OWON’s 30 years of manufacturing experience and FCC/RoHS compliance, providing high-value solutions for B2B projects.

Have an M1 Pro 32GB which recently started feeling slower. VSCode multiple tabs is a problem. Generally the UI feels less snappy.

I've switched now to a desktop Linux, using an 8C/16T AMD Ryzen 7 9700X with 64GB. it's like night and day. but it is software related. Apple just slows everything down with their animations and UI patterns. Probably to nudge people to acquire faster newer hardware.

The change to Linux is a change in lifestyle, but it comes with a lot of freedom and options.

> IMHO EU should just drop everything and do China level or even beyond transition to Solar and similar.

The funny part is that we dropped our home grown nuclear power in favor of renewables, which are mostly provided by China since all the biggest manufacturers of solar panels and windmills are Chinese.

Why should we "drop everything" to pursue renewables when no one else is doing it? It's obviously not the right choice, we should be consolidating our nuclear power reactors AND developing renewable

Look into the history of pro renewable in Europe, the foreign ties, the whole german/france nuclear scandal, the common European electric market abomination, were not fighting China or the US, we're fighting ourselves

> Had EU already switched to renewables 4 years ago there wouldn't be any disruption by the war Russia started in Ukraine.

There are plenty of things you cannot do with electricity, try to make fertilizer or medicine with electricity instead of petroleum derivates

That's a great idea actually!

An example that came to my mind: squeezing fruit juice requires a lot of dexterity. But if we sold pre-chopped fruit bits in a standardized satchet, then robots could easily squeeze the delicious and healthy fruit juice from those! And health-conscious people drink fruit juice every day, so this could easily be made into a subscription-based service! A perfect business model right there. You could call it iJuice or juice.ai or even Juicero.

Interesting observation in the last bit, research indicates links between PTSD and symptons often associated with autism: https://neurodivergentinsights.com/ptsd-and-autism/. That said, PTSD is treatable to a point, if you can verbalise what situations or what experiences cause your ptsd type stuff, treatments like EMDR may help for you.

Not sure which country's perspective you are taking but you may wish to consider that the largest part of the subsidies building renewables are EU subsidies which to the largest chunk are financed by Germany which makes a contribution to the EU budget far above any other. So if you look at Spanish solar or Danish wind (not to mention anything in the East where the % contributions of EU funding are very high), a good chunk of these are actually subsidised by the EU and thus to large degree by Germany.

If I'd have to guess then I would think that Ceph is the only one who is truly open source and does not feature gate important parts to paid enterprise users.

I did go through this couple of years ago and we ended up with Ceph as well. Combine this with reusing existing hardware that was very suboptimal for Ceph in several ways, it was a pretty bad experience and in the end for our use case AWS was able to offer a good enough pricing that the performance and reliability of S3 was a better deal than managing it ourselves.

If I would do it again then I would make sure that I have the hardware setup that is ideal (plenty of SSD's for metadata, every spinning disk directly addressed as a single OSD, sound network topology and fast enough NIC's) and probably use Rook instead of cephadm. The monitoring, configuration and documentation side of Ceph is however still quite sad, it was really hard to figure out why something is slow and how to tune things faster.

That said, if the Enterprise options are performing better or you at least get good support for tuning and optimizing then the alternatives could be well worth consideration.

> I'm starting from real world governments and their real world behaviors, not fantasy.

In the real world, many dictatorships have formed without UBI. Yet you regard UBI as a certain step towards it and even pretend its a hard argument against it, meanwhile the problems root causes you are concerned about are entirely detached from UBI. You are simply projecting.

I cant state it any more clearly. You are a lost cause.

The old uBlockOrigin (which Google depreciated) had an auto-decline, so I didn't see one of those cookie banners for years... the new Lite version, however, doesn't seem to have that feature.

People say “agents not RAG”, but one framing is that this describes RAG where the database is a file system and bash is the query language (with other cli tools installed it can use, including curl, jq, grep). With writing its own notes on the filesystem structure and maintaining them as a way to “index the database” It is still using code to selectively grab the chunks of data it needs rather than than putting everything in context. It’s just better RAG?

In JS, modules were a massive improvement pretty much from day one. They were fairly quickly adoped and worked well. It's been a huge quality-of-life improvement, especially with the latter addition of import maps.

I just wish we'd get working, well-supported modules like that for C++. I tried them once, but support was abysmal and I won't touch them again until they work nicely everywhere.

It’s slow. Example: quicksort [] = [] quicksort (p:xs) = (quicksort lesser) ++ [p] ++ (quicksort greater) where lesser = filter (< p) xs greater = filter (>= p) xs

It’s really complicated. Everybody includes lenses https://hackage.haskell.org/package/lens I don’t want to read all that stuff just for imperative syntax.

It’d both slow and hard to read. Compare these two: https://benchmarksgame-team.pages.debian.net/benchmarksgame/... https://benchmarksgame-team.pages.debian.net/benchmarksgame/...

The c examples complexity lies in using SIMD. If you know simd it’s easy. You should know simd, it’s useful. The Haskell example is drivel. Long complicated and in the end hopelessly slow compared to the c example. You could als use simd in Haskell, but then it would just be C with extra steps.

Succeed in which way? Some empty career in some soulless company that doesn't care about you? Some miniscule extra cash on the account? Those are not proper life successes in any meaningful way.

Most of engineers are rather introverts with rich internal life and strong imagination. You can lose most of it and transform for more 'success' over time, but at great costs to yourself. I am not arguing against say better communication or organizational skills, we all benefit from it, but you can't avoid various form of highly functioning sociopaths once you climb above ground level. Those tend to drag weaker individuals down to their rabbit holes. That's the core of the 'politics' I've seen over past 20 years in all corporations I've worked for. Looking at people and measuring how good relationship is right now, how you can use them, how worthy they are. Forging alliances always doing such calculus in your mind, everything is a chess board, everybody is a chess figure.

Don't forget how you behave and think at work will end up permeating rest of your life, you are just you in all places. One example I see very consistently - folks promoted to more responsibility get over time much bigger egos, very few are immune to this and one has to realize it and actively fight it to avoid it.

Be a good human being, help others in need, be a properly good parent, husband, son/daughter, friend. For many folks high on organizational charts, in above metrics they failed in life while drowning in money of career. No thank you.

I can buy your arguments, but not in the context of this game.

Saying "I'm tired I'll go work more silently" is just reasonably workplace behavior. Telling your coworker "can we sit down and talk about this somewhere more quiet" is just reasonable thing to say to improve productivity. Saying "This meeting is a bit unstructured and i feel if would be more productive to write out an agenda" is not breaking a mask or being an ass, it's focusing on getting shit done for everyone. Sending an email about concerns about unclear and un-mensurable performance in a post-meeting summary is productive and useful for the team (and less socially draining than doing it during the meeting).

All humans mask. Autistic people are simply more prone to "over-mask" or mask things others don't. But a-lot of masking behaviors are mal-adaoptions from childhood. A distraction-less focused and structured work environment helps everyone, so be the ass and enforce it. And particularly engineering fields have a higher tendency to attract (certain) autistic traits, which just further makes speaking out even more valuable for everyone involved.

Simply put; The game makes being "breaking the mask" a negative thing, and a failure case for the game. But all options that break the mask seem to improve energy and social connection. (which goes entirely against the supposed benefit or purpose of masking)

One does not have to be a carpenter to have furniture, and one does not have to become a software engineer to get computers to do things.

Unless you are into it, you’ll realize that it’s quite a grind and your time is much better spent getting somebody who is into it (and thanks to that became an expert to it) get computer to do what you want faster and better.

There’s nothing wrong with trying it, if anything to find out whether you are into it or not in the first place. If you stick to it, chances are you are into it—just like you don’t become a carpetner simply because you want to have furniture: perhaps that’s one of your initial impulses, but you are also mentally compatible with the process and tick some other boxes.

On that note, what does it mean to be “into it” when it comes to programming? What is a “good” reason to become a software engineer? To me, it’s about the inclination to tinker, the eventual payoff of the dopamine rush from seeing puzzle pieces fall together, and the desire to own the process, do things by yourself even as you stand on the shoulders of giants.

Between these things, LLM-driven development strikes me as somewhat weak on tinkering (there may be some, but less, and much less precise and deterministic), and very weak on the desire to do things by yourself. Of course, that shouldn’t invalidate anyone’s personal experience.

> They are so fanatical that many groups are unable to use them.

> Coderberg is hostile towards private repos.

Disclaimer: I'm a member of Codeberg e.V., though not part of the presidium or any official representative position.

We're a non-profit (charitable) with the explicit goal of being host to free and open source projects. We run on donations, donations that are made with that specific goal. Why should we provide storage and git hosting for proprietary projects? That is not and has not been the goal of the entire organization. Yeah, I guess that makes us unusable to many groups, technically. But Codeberg was founded for that specific purpose, after all we're a nonprofit, not a business.

If you want to host proprietary projects, Codeberg isn't the place for it and it doesn't want to be.

Also, no you won't be immediately banned if you make 3 private repositories. I myself have a few private repos, mostly projects that never got anywhere close to finished but also personal notes or my nginx server config.

> That would help with both the debt situation and our exports.

But the debt is denominated in euro. If you leave euro and create a new currency, the bonds will still be in euro, while your new currency will be worth much less. It's basically easier and less painful to default on the spot than to go through this.

I honestly can't understand the urge to get bankrupt. France is already famous for the revolution and eagerness to protest but this looks like you want to cause chaos just for the sake of it.

Not sure if this is what you had in mind but here are the links to the two papers that I was referencing.

[1] covers the first 40 years of databases. [2] fills in the gap of the last 20 years and gives their thoughts on the future.

My apologies, the first one was actually Stonebraker & Hellerstein and didn't involve Pavlo. They're both excellent papers though for anyone working with data.

Stonebraker, for those who don't know, is the creator of Postgres, a database you might have heard of.

> Nuclear is already the most expensive source of electricity

Lmao, meanwhile France had the cheapest clean electricity of the developed world for the past 70 years, while Germany paid 2-5x more depending on the period

It's only expensive for new built reactors in Europe because we've given up on the technology a long time ago, countries which made it a national priority and kept the know how are still enjoying cheap nuclear energy. If Germany didn't spend decades and billions on green lobbyists in Bruxels the story would have been very different

Why do you think China is building 30 new reactors right now and have planned for dozen more? They have all the coal and manufacture the vast majority of solar panels and windmills worldwide but they still go for nuclear.

Almost as if having a diversified energy mix is desirable...

Defining first-order logic doesn't really require set theory, but it does require some conception of natural numbers. Instead of saying there's an infinite set of variables, you can have a single symbol x and a mark *, and then you can say a variable is any string consisting of x followed by any number of marks. You can do the same thing with constants, relation symbols and function symbols. This does mean there can only be countably many of each type of symbol but for foundational purposes that's fine since each proof will only mention finitely many variables.

Allowing uncountably many symbols can be more convenient when you apply logic in other ways, e.g. when doing model theory, but from a foundational perspective when you're doing stuff like that you're not using the "base" logic but rather using the formalized version of logic that you can define within the set theory that you defined using the base logic.

While I have no opinion on the "holy grail" part, I think them varying massively is the point.

A lot of locks require a bit of finesse as well, like pulling the door towards you or pulling the key out just the right amount, which would be an interesting challenge. Especially if the technique isn't known ahead of time. Given enough time (and frustration), people can generally figure the "finesse" aspect out for a lock.

Location: Jakarta, Indonesia Remote: Yes; been working in remote/hybrid settings since 2019 Willing to relocate: Yes Technologies: Kubernetes (self-administered kubeadm, GKE, EKS), Proxmox, Python, Golang, Bash, PHP, MySQL, Postgres, Redis Résumé/CV: https://id.linkedin.com/in/nugraha-nandiwardhana Email: nugraha [dot] nandiwardhana [at] protonmail [dot] com

Hi there HN folks. I'm Dhani, and I've been in the tech space for the past 14 years or so (aka since I graduated).

I started off building VB.NET automations around Excel and SQL server as well helping revive a left-for-dead DWH project for a bank, before venturing into telco (where I built reporting and online self-assessment platforms), consulting (implementing K2 BPA for an assortment of local companies and MNCs), e-commerce (gamification, reporting) and fintech.

Fintech also happened to be the part where I took a somewhat sharp turn in my career and delved into the infra/devops/SRE side of things; which exposed me to contanerization and orchestration, and eventually later towards Kubernetes.

As of now, I'm in a probationary status in a local fintech/crypto exchange, juggling between helping engineers and being a devops ticket monkey -- setting up Jenkins pipelines, GCP resources, the works.

I enjoy doing R&D stuff as well as writing automations -- in a previous job posting, my probationary project was to migrate entire deployments from Flux CD into Spinnaker, which included figuring out how to integrate HC Vault without exposing secrets in the pipeline itself.

If you look at my LinkedIn, I have details on the cool stuff I've worked on.

I'm open to infra/SRE/devops as well as backend roles, regardless of seniority -- I've led a team for ~3 years but has since decided that being an IC allowed me more technical work, tinkering around with stuff and writing documentations (which I enjoy more). Being a tinkerer and loving to venture into the unknown, I have no qualms about learning new frameworks, technologies, or whatever esoteric stuff you need me to get up to speed to.

Rubbing your eyes thins their keratocyte layer and is a risk factor for eye deformation and damage: https://pmc.ncbi.nlm.nih.gov/articles/PMC6848869/

I have no idea if the technique you linked works, but anyone stumbling across this should be aware that it has very real and potentially serious risks - if rubbing them at all increases your odds of keratoconus, just think what 10min/day for months will do.

For one: https://pmc.ncbi.nlm.nih.gov/articles/PMC2949584/

These drugs require constant monitoring by physicians that understand what to look for, that are actively involved in adjusting dosage, for them to be even remotely safe. Muscle atrophy is considered an "uncommon side-effect", but that's just because most studies aren't performed over long enough periods of time. People tend to be kept on statins permanently. And that changes the safety factor considerably, as it does with any medicine taken over years.

My anecdotal evidence is based on multiple family members on these drugs and how even in Norway, with our fairly good healthcare system, it's not monitored sufficiently to avoid issues. There's a lot of strong feelings around statins as is apparent in the other response to my comment, but claims about them being safe except in outlier cases is simply not true.
