Victron is good stuff and it is made to last. They're a big supplier to maritime integrators to provide power on board of ships of all shapes & sizes. I've yet to see a Victron inverter fail before the end of the lifetime of the installation it was a part of whereas most other inverters including Xantrex and ABB tend to die after a decade or so. Which isn't bad but still it can be a big hassle to replace an inverter if the form factor has changed.

Also: consider decoupling your battery charger setup from the solar portion, this will give you a lot more flexibility in terms of siting (you can then place your battery and charger where you want on your local installation). You can use HA to bring your battery online when it is most needed and even when to charge it based on the outputs of multiple fields of solar, an integrated solution really only works with a single inverter or a set of inverters of a single brand.

And if you can stay away from stuff that requires an internet connection to some manufacturer, not all upgrades are positives and your data shouldn't be going there anywhere. Also it probably isn't a good idea to hand over control of a grid connected device to another party, especially when that device has firmware that can't be audited.
The article here is an ad. I guess it's not a badly written advertisement, but it still reads as an advertisement which isn't exactly a desirable trait in an article.
> "The prime minister needs to show his working: he cannot deliver this reheated, empty pledge without more maths teachers," shadow education secretary Bridget Phillipson said.

Correct. Important context for this is the ongoing balloting for strike action over teachers pay. Anyone who can do maths can read their own payslip and know when they're better off in the private sector doing anything else. The recruitment shortage is serious: https://committees.parliament.uk/committee/203/education-com...

> A 2022 report by the National Foundation for Educational Research shows that the teacher supply challenge is marked particularly by a lack of physics, chemistry and maths teachers. For physics, only 17% of the target to recruit 2,610 trainees was achieved, with only 444 new entrants. The Committee was recently told that at this current level of supply, it would be impossible to carry out the Prime Minister’s proposal of requiring pupils to study maths until 18.

In other words, this is already impossible, and no amount of "mindset changing" (wishful thinking) is going to change otherwise. You're only hearing this now because the local elections are soon.
It isn't always a shock when a company fails, and Virgin Space is a prime example of that.

They flew something like a handful of missions in 20 years with an unscalable platform and to my knowledge they never once received money to put a payload into orbit.

They are totally incomparable to SpaceX, the company that is putting more tonnage into orbit than any other entity, corporate or governmental.

Schools - and this is a problem in the UK as well - are incentivised to optimise for evenly distributed mediocrity, instead of allowing people to reach their potential.

Now, I'm not talking about race here - this is from my perspective in the UK.

Ultimately we need to split the education system up. Putting the next Einstein and a violent, disinterested drug dealer in the same school, let alone the same class, is a recipe for disaster. And no amount of giving the idiots targets will fix them, but it will make life hell for people who actually want to learn.

This one-size-fits-all, optimising for mediocrity attitude is evident in the move towards mixed sets. The idea is that by putting the intelligent kids and the violent, intentional failures in one class the intelligent kids encourage the others to improve. But in practice they're vastly outnumbered, so they just get relentlessly bullied and don't learn anything. I know, because it's happened to me.

And it's evident in the way schools handle behaviour. I was kicked in the head at school, twice, by a load of thugs. I'm still very slowly recovering from the post concussion syndrome. At this rate, I am likely to fail my exams and not get into what used to be my backup uni. It was an entirely preventable incident if only:
- The school had entry requirements (it's meant to be a specialist technical school, but thanks to our enlightened government new grammar schools are banned.)
- The school was able to expell them before it happened, what with them spending the whole time messing about and attacking my friend
- The school had temporarily suspended more than the single person who punched my friend in the face when the whole group was there
- The police, with it's restorative justice, letting under-18s get away with anything, policies, had actually done something the first time

But they didn't, and now my life is ruined, and they got away with it. Because of a series of brain dead policies that are disconnected from reality and pushed by people similarly disconnected from reality.

The school system should have separate schools for high achievers to allow them to succeed without violence and with the fast pace and high expectations they deserve. If people want to go to those schools they can put the work in, behave, and pay attention. It's time to stop feel-good policies about second chances and equity and optimise for success and meritocracy.

It reads very much the same in France. The average pay for a Business School graduate is 5-15% higher than that of an engineer.
In milps you can have an objective function to minimize/maximize and continuous variables. The techniques used are based on the characteristics of the mathematical space of the possible solution and methods to reduce the size of space that you have to look into.
The solution of milp solver are provably optimal.
CP allows for constrains that are difficult to model and/or solve in milps (or even mip).
There is some overlap between the two. For example, presolving in milp is basically a generalization of constraint programming.
What's this thing with the absolute wish to centralise everything?
The Internet is decentralisation, it's birth is interconnecting networks, having one massive network being just not scaleable.
The web is a decentralise content system, allowing anybody to add content easily is the reason it scaled. Same goes for the domain name system.
Companies like Twitter HAVE to decentralise their system in some ways to make it scale, because centralisation does not scale (using CDNs, caches, replication, etc...).

Centralisation do makes seems much simpler to build, but it's not a strength, it's a big weakness and create single points of failure.

Semantic search 85 pages in seconds in the browser
SemanticFinder now offers an easier way of pre-indexing files. Just like in all ML-flows the embedding calculation is the computation-intense part, so if you do this beforehand and load it in your browser, calculating cosine similarity is trivial (for a few thousand iterations).

It has the nice side-effect that this also allows for external computation of embeddings where you might have faster hardware than you're client device.

One could add so many features like adding full-text search by checking if the index contains certain keywords.

GitHub: https://github.com/do-me/SemanticFinder

In a way, your browser can become the vector DB.

Hiring for tech companies and businesses is a tediously long process. IT staff augmentation services can be a valuable strategy for startups that are not too committed to a particular mode of operation, especially for startups. This is especially true in IT and software development, where companies increasingly turn to IT staffing solutions and committed development teams.

I am looking for a guide that can help startups navigate the process and find the best fit for their business. I found one article, can you recommend a similar guide?

Yeah :) Thanks for your infodump! I'm mostly curious how you achieve the insane amount of "clutter" in these images - is it done by referencing a specific artist or style in the prompt, or just by some difficult-to-find key phrase? I haven't been able to get anything near.

Tone mapping is used for HDR screens too, if the screen has got less nits than the video.
Anyway, probably it's something else, you will have more luck asking DaVinci Resolve developers. It could be they are ignoring the screen color profile, or they set something wrong, there are so many things that can go wrong.
> Long gone in the past1 are websites that purely displayed static, seldom changing content to visitors. Today, almost all user interfaces are web applications instead of websites.

Most of the websites I visit are static and when they are not their dynamic content is annoying. Look at new vs old reddit for a good example.

Most websites would be better off being statically rendered.
They are not required for making orbit I suppose, only for safe reentry. But can't know how well it all works without trying, so going even if confidence is not perfect.

Nice idea, but at some point GPT + "generate code to implement this patent", may develop plausible enough code to satisfy most Patent Examiners. I don't see this fixing the issue in the longer term - maybe a "use it or lost it" rule + much shorter enforcement period for software patents is what is needed?
Yes, but Twitter used to be much more solid prior to you know, losing a lot of its work-force. Reddit, on the other hand, has improved since a few years ago
AFAIK there have been several attempts at this, but Mastodon deliberately does not support arbitrary search and some communities are extremely hostile to having their posts scraped.
Engineering is not glamorous here at all, which I think is a shame because it's a productive, generative, job, with good qualifications needed, and it has a good earning potential. It's much less sought after than working in "marketing", yet probably on average a better job in many ways.

Software Engineering and "working in IT" does have a different perception and is considered "cooler", even though the vast majority of our IT jobs are awful.
Go to any airport an Asia and you will find plenty of drinking water fountains. Sure, sometimes the cold water is broken but at least it's sanitary drinking water.

Meanwhile Frankfurt tells you that the tap water in the restrooms is safe to drink. Absolutely absurd that Airports where you are effectively stuck for possibly hours and are paying for that priviledge can get away with not having to provide basic neccessities.
> they're just two radically different and largely incompatible audiences

This is incorrect, and I think you're maybe missing some context. What is being referred to here isn't esports players being whiny or particular about changing a game in a way that would hurt casual users. What's happened a few times recently is that Nintendo were very heavy handed in cracking down on things like Smash Brothers e-sports tournaments: https://www.theverge.com/2022/11/30/23485811/nintendo-smash-...

So here they have already made a game that is beloved by both casual players and professional players, and they seem really keen on cracking down on the latter group. They don't need to take any special steps to cater to e-sports players or tournaments, they just needed to not go out of their way to crack down on them.

All the important accounts I followed on twitter switched to Mastodon when Elon got his hands on the platform. I don't want Mastodon to be a Twitter alternative, really, even if it is only for some circles.

The endless Twitter drama and hot takes being pushed in your face by Twitter's engagement algorithm is tiring. I'd be happy if that dredge would be kept away from the Fediverse. It sadly isn't, but at least the situation hasn't gotten nearly as bad as Twitter's thanks to smaller communities that aren't afraid to practice moderation. I know the idea that someone might kick you off your server for being toxic is a problem for some free speech absolutionists, but personally I'm glad to see them return to Twitter/Truth Social/Gap/that weird web3 Twitter without moderation.

If you're trying to build a brand, Twitter is a lot better. Their fake engagement statistics below every post help a lot when it comes to inflating popularity statistics and you can't use ads on Mastodon to force your brand down other people's time lines. Only people who genuinely want to see what you're saying are seeing your content and that's why Mastodon will never replace Twitter:you can't buy your way to some twisted sense of popularity.

I doubt complete centralisation will ever happen. We'll probably end up with a sort of email light, where it's quite easy to set up a smaller instance but the majority of users flock to a few popular servers the same way Gmail and Outlook have replaced ISP mail accounts. However, because Mastodon and other Fediverse services don't really have a way to do AI moderation in a way that pretends to work well enough, I don't think scaling up to servers of more than a few thousand people is really viable.
hmm, well Twain was quite committed to the idea of perpetual copyright, so seems fitting somehow.

SvelteKit's routing pattern is anything but clean. It uses filesystem based routes where every file is called "+page.svelte" (or +page.server.js/ts for API only routes).

For anything but a demo app with just a couple of routes it's a headache to navigate.

Edit: Another smell of the routing system to me is that you need to resort to complexity like this [1] to have anything but top down inheritance. I love Svelte btw and have used it in many projects.

My introduction to calculus was “Calculus Made Easy” by Silvanus P. Thompson and I always liked math profs who actively worked to show math for what it is: useful, beautiful but not about the symbols or the jargon. “Any fool can calculate!” I think is what he says in the book.

I did some math in college and when I started knowing how to analyze the behavior of functions (and developing the mental math tools to imagine what they look like without having to actually draw them) that’s when I felt like I was kinda getting it
Obvious in hindsight but I hadn’t thought of using a non-optimizing solver for an optimization problem.

I think constraint programming may get more popular because of LLMs. One of the big issues with them is translating your problem into constraints. It’s tough for people to do that. But an LLM can do that well, even just to make sure its own solution is logical.
> What matters in social networks is scale

What value does scale have, if you get only lazy retweets and likes and low-quality responses? I don't need 'eyeballs-on-tweet' kind of exposure, but interesting discussions. I get these on the Fediverse, and yes I managed to pass the 15 minutes selection of an instance. Which isn't all-too-important either, as instances federate with each other and you can migrate later, if you wish.

Btw, for an example pitching that Twitter isn't a good replacement for Mastodon, see yesterday's thread: https://news.ycombinator.com/item?id=35578226

Being in the Netherlands makes this very challenging indeed. I am from the Netherlands but don't live there anymore.

Not much solar energy on those days.
Incandescent bulbs are not full spectrum, though. They are on the warm end of the color temperature scale, much more "orange" than mid-day sunlight.

The good news is that you can get LED bulbs in any color temperature you like. My house is full of "warm white" LED bulbs and I could not tell any difference in brightness or color when I swapped them in for incandescent many years ago.

> forcibly strip mining the ideas of independent creators.

this is the same argument that patent proponents had, because patents protects the little guy.

And yet, most copyright enforcement occurs via large corporations who have an interest in doing so to further some other goal as part of a strategy to gain monopoly. Patents as well as copyright is but a tool, and any tool can be more powerfully wielded if the wielder is more powerful!

The little guy is better off without copyright imho (but that horse has already bolted).
The months spend on building these, are often spent on becoming domain expert of one or several sub domains, build into the artifact. Which is not visible to the outside world. Its similar to hiring one or several consultants, but the consultants were that one person, digging into fluid dynamics and what not to write that one system. The problem is often not in the software, but in the "domain" self-schooling one has to go through, to understand the process happening. Like sending a person to university again, but on the clock with a deadline.

Best example of an alien artifact i could come up with on the fly: The using parties do not understand it, but can reuse it. They will have a hard time modifying it. To understand the properties, a deep understanding of math is needed, and how the inverse square root can be mapped to the binary properties of a float.

How could Space X even afford fund a mission to Mars? There is no way that can be profitable .

What they are doing now is cool but they are still a business which offers a launch services at a competitive price and a satellite internet provider themselves. How does an exceptionally expensive (especially in this financial environment) Mars mission fit into that.

I highly doubt Space X could ever realistically get to Mars before NASA. Artemis seems way more promising than SpaceX as far as manned space flight is concerned.
Just another hollow promise from a prime minster and administration that are staring electoral defeat in a years time.

The trend at the moment is to announce 'reviews' that capture headlines while doing absolutely nothing about the actual problems. When this doesn't work, get back to fighting the culture wars.

For example, we've had multiple reviews, and actual announcements on the legal side, which replicate already existing powers. It's a joke.

It's cliche to say that the current administration is the worst we've ever seen ... but the last decade has demonstrated that cliche as fact in the UK's case.

Something not mentioned here is that software itself is rarely the subject of a patent. Instead, it is a "computer system running software". This, I think, is a trick to get around software itself not being patentable in some jurisdictions.

I really like this proposal but it lays bare the fact that the invention lies entirely within the software itself. When the patent industry has been pretending for years that the "invention" is a hardware thing that could, optionally, use software.
