Also in NL and I work for a heat pump company - I don't know the specifics but for as long as I've worked here we've never not been hiring heat pump techs. (https://quatt.recruitee.com/)

I actually am hoping that better grid coördination could help a lot with the problem you describe, there's a few companies in the space but I can't think of big ones in NL. In the UK you have Octopus Energy which has effectively made a (virtual) power plant by managing individual assets.
You bet, here's a quote from Wiki:

Note that this is compared to 6% the previous year, the decrease partly due [1] to a security failure where they got ransomwared and may also have leaked people's info [2]. In absolute amounts, that's 22 billion in 2023 down to 14 billion in 2024.

The company also holds assets worth ~300 billion, an increase of 26 billion compared to 2023. [3]

I had a friend/former mentor who proved that object pools are slower in Java once GenGC was introduced because they create pointers from the old generation to the new. He also authored the fasted XML parser of that era and previously helped me land a project everyone but us and our boss said was impossible because Java Is Too Slow, so I take him at his word.

So unless those pools are full of primitive data types, you’re going to cause more frequent full GC pauses, and longer due to all the back pointers.
Sure, but do those ads generate enough revenue to stay in business?

It recently occurred to me that the crazy expense of the US Healthcare system (most expensive in the world, while also being terrible quality) might be by design: it keeps you desperately tied to your jobs. Just another threat enforcing that weird modern serfdom the Americans are so fond of, along with their unsolved homelessness and massive prison industry.
Of course not. Multiple things can be (and are) factors at the same time. I'm not asking people to ignore COVID, I'm asking them to not ignore this.
As I mentioned in my comment, you can also observe the escape analysis from the compiler and know whether your code will allocate or not, and you can make adjustments to the code based on the escape analysis. I was making the point that you technically can write allocation-free code, it is just extremely rare for it to matter.

sync.Pool is useful, but it solves a larger class of problems. If you are expected to deal with dynamically sized chunks of work, then you will want to allocate somewhere. sync.Pool gives you a place to reuse those allocations. C# ref structs don't seem to help here, since you can't have a dynamically sized ref struct, AFAIK. So, if you have a piece of code that can operate on N items, and if you need to allocate 2*N bytes of memory as a working set, then you won't be able to avoid allocating somewhere. That's what sync.Pool is for.

Oftentimes, sync.Pool is easier to reach for than restructuring code to be allocation-free, but sync.Pool isn't the only option.
Kinda sounds like a "TBS-driven" approach. Certainly helpful.

Other things I get out of blogging, in addition to Andy's points:

* I can link people to my carefully considered thoughts on a subject instead of needing to write something up each time.

* While most people don't read what I write, some do, and I've had good conversations and friendships come out of it.

* It makes me a better writer. In my professional life I can write things much faster and better than if I wasn't also blogging for fun.

* LLMs learn from it. Our future may be run by machines, and if so I want my perspective to be one they consider.
I thought perhaps hen hadn't quite digested what it would mean for only a small class of elites to be in the pool that gets picked from.

By excluding over 3/4 of the population, we would hardly get what we think of as democracy.

With those exclusions, the power of being a citizen would increase dramatically and the lottery would make it unlikely bands of eligible citizens would unite to expand the electorate but instead would seek to make membership more stringent, like DPRK's haeksim.

Choice by lottery would also fail to exclude men who have no desire or capacity to do whatever job it is they pulled. I do not know what they did in ancient Greece but in modern times that would lead to a bureaucratic class with the leader being only a figurehead at their mercy--and at times that would be very good. But the bureaucrats class would not be the voice of the people, would not be democratic.

I felt this was obvious from the exclusions and so didn't see the need to elaborate.

Unclear whether that would bear fruit, given how socialized healthcare systems have a bad reputation of long wait times.
Yes we have no public roads either for miles. Privately maintained easements instead. I built mine first with just an axe and shovels, later with a backhoe. Sewer is private septic. Water we had to dig a private well. The electric coop is paid for by users at full cost by their own extensions.

This works amazing as taxes and subsidies are basically zero. You pay for what you use.

This would work very well for medicine/procedures which are known to work very well, to both doctors and consumers. This includes medicine which is already OTC (pain relievers), but also probably anything they can do at an urgent care: x-rays for broken bones or sprains, throat cultures, antibiotics (drug resistance is complex for this but people generally know they work).

Where costs will inevitably get complicated are:

1. emergency medicine, where the purchaser is in severe pain or possibly unconscious.

2. conditions without cures, or possibly even well-established treatments, and there is thus active experimentation and disagreement

Both of these are unpredictably expensive to an extraordinary degree, and the second category is sometimes rare enough that economies of scale don’t come into play for individual conditions.

I think government coverage of emergency medicine, aka ERs for severe injuries, is relatively uncontroversial due to its nature of treating unconscious patients.

However, that other category is very large in modern medicine. It includes all chronic conditions without cures, for which many options are available and improved techniques are constantly sought - and it includes complicated conditions where treatment has risks involved, which is basically a huge range of surgeries.

The problem in these areas is that the consumer does not have adequate understanding of the efficacy of what they’re buying, yet they’re driven to buy it strongly by pain and suffering. They are likely to want to do whatever a doctor or hospital tells them to do.

What is needed here is a consumer advocate with medical knowledge to keep prices consistent. In the US, this is provided by a mixture of regulation, medical malpractice lawsuits, and insurance companies.

Insurance companies are now failing in that role, but removing them entirely without any sort of replacement is going to leave the courts as the major vehicle to manage the costs - that isn’t a system renowned for efficiency.

This is actually a bit of a match made in heaven for Nix. The Steam Deck runs Arch with immutable root, which means most of the AUR packages won't entirely work. So you need a package manager which respects immutable root, supports atomic upgrades with Arch and has a package selection similar to the AUR. There are a few options, but the best one really is Nix: https://repology.org/repositories/statistics/newest

Given that package management on the Deck is traditionally handled with Flatpak, Nix seems like a great alternative for power users with storage to spare.
To be honest, the naming is a bit confusing. Here is my understanding:

- Nix: build system and package manager (available on Linux and macOS)

- Nix: language used to define how to build packages

- nixpkgs: Nix package monorepo

- NixOS: Linux distro that is fully managed using Nix (language), has Nix (package manager) built-in, and is defined as part of nixpkgs

Good point. However, it's almost impossible not to conflate the two (healthcare overall and health insurance) because, unfortunately, health insurance is pretty much required for healthcare. The credit card companies would be a good measure of GDP if they were required for every purchase.
Western reductionism/Laplacian determism was falsified several times by counterexamples like quantum superposition, Cantor diagonalization etc.

The System Identification Problem has also been shown to be equivalent to the halting problem.

https://philarchive.org/rec/DIEEOT-2

The common joke about spherical cows in physics also points to the predictive, descriptive nature of the field.

The equivalence of various QM interpretations also points to the scientific realist views as being incorrect.

Rice's theorm, Gödel, Wada property etc... also demonstrate the problems of confusing the map with the territory.

There are further topics like indecomposable continua that arise frequently and naturally in nonpathological dynamical systems. Especially with time delayed ODEs, Hamilton systems etc?

Are you arguing that Hamilton systems aren't 'physics'?

The value of western reductionism is finding 'effective procedures' but teaching it as being reality is more about didactic convention and convenience.

'Hard science' is a term for study the universe through theories, hypotheses and experiments.

It is still about making predictions that match observations.

This it is descriptive vs prescriptive.

Yes, it’s a similar situation in the US! Many folks (especially on the west coast, where summers have historically been mild) don’t have an AC, so big motivation to install a heat pump is to add AC! Unfortunately, plenty of one-way ACs are still being installed; each of those is a missed opportunity where a heat pump could have been put in and decarbonized heating at the same time

Show HN: I built an AI assistant to help my girlfriend learn Figma for Design
Me and my GF recently moved abroad because I got a job offer in Europe ( we are south americans ). She is struggling to find a job and started to learn UI and UX and creating a portfolio using Figma for the design. I am a web developer and decided to help her creating an AI powered app capable of accessing all the documentation of Figma to answer questions and help her learn it quickly.

I think this app might be useful for other people who are entering on the field, so I decided to make it free and open source.

To use the app no login or signup is required and it's completely open source.

The source code is available in my github repo: https://github.com/Saraceni/FigmaAiAgent

I would love to hear from other professionals any feedback or suggestions on how to improve it and contribute to the learning of Figma.

Compromising your user account is pretty bad. Let's see:

- Can trivially exfiltrate all your data.

- Can generally break Mac OS's sandboxing. (There's no shortage of examples demonstration that Apple really doesn't try very hard to make Mac OS resist attack by programs that are sort-of-sandboxed.)

How to Use DeepSeek AI to Find Cybersecurity Jobs
I see it a little differently.

I was a young founder that turned into an old founder. Same company for 40+ years, no exit. We talked with VCs and potential investors many, many times. Once we were past a certain age, they became much less interested and my take on the reason is:

At a certain point, we had a lot of experience running a company. All parts of it. When we interacted with VCs or potential investors, the things they can pull on a 20 year old were obviously not going to work on us. I'm talking about financial slight of hand, terms in contracts, etc.

As for the disruption, I feel it's not the young that do it. Some companies started from experienced founders who couldn't get it done in their current company and went on to found a new, successful company:

* Instagram

* Netflix

* Loudcloud

Beautiful love you have there, your significant other would be very lucky.
You can and this will be simple and reliable.. but that's solving the different (and easier) problem that the post. In the post, author wants to have still have parsable JSON _and_ a signature. Think middleware which can check signature, but cannot alter the contents, followed by backend expecting nice JSON. Or a logging middleware which looks at individual fields. Or a load balancer which checks the "user" and "project" fields. Or a WAF checking for right fields. In other words:

> Anyone who cares about validating the signature can, and anyone who cares that the JSON object has a particular structure doesn’t break (because the blob is still JSON and it still has the data it’s supposed to have in all the familiar places).

As author mentions, you can compromise by having "hmac", "json" and "user" (for routing purposes only), but this will increase overall size. This is approach 2 in the blog.

It's kind of a joke to conflate either of those presidents with social democrats.
One of the more salient critiques of the Democrats is that they need to stop taking victory laps when they pass legislation and short-changing the implementation. Part of the loss in this last election was because of how little of what they’d gotten passed had actually made its way into the world (well, that, and a total inability to get a message out, followed by a total unwillingness to say whether what they did was good or not, but at least if they’d actually implemented some of what they’d passed, it’d be harder for people to ignore what they’d done.)
> Administrative costs include spending on running governmental health programs and overhead from insurers, but exclude administrative expenditures from healthcare providers.

From what I've read, healthcare providers spend an inordinant amount of time and effort dealing with insurance companies.

Ecclesiastes
To me, Rust feels as if it had sprung from the same mind. Or in the case of C++, set of minds. Who have a common mindset. I sadly don't critize rust's general design choices constructively. It's more of a public realization, '"C++ mind-set compatible" might just be the quality to describe the specific aroma I dislike in this melange".

I'm fine with robust languages with very strong type systems, I think. Are Haskell, ML, F#, Scala in this set? Robust and very strongly typed enough? I don't dislike their taste, even though I think I've had enough scala, specifically, for this life time. If these aren't in the set you're thinking of, I'd like to know what makes up that set for you.

If you are sold junk complain to the seller, then if they don't refund you go ahead and raise a dispute. If they offer a return then ask them to refund you ahead of time, in full, and to provide a label for the return.
Intel ruined an Israeli startup it bought for $2B–and lost the AI race
I spent quite some years performance tuning large Java systems, pre-warming server JVMs and then many hours staring at visualgc, a small Sun engineers tool for watching the various memory pools including generational GC, it was very satisfying work, and also pretty useful for uncovering bugs and race conditions when the systems were under load.

The GC advances that came along helped a lot, especially over the stop-the-world early days of Java GC, along with all the JVM tuning parameters that were gradually exposed for tweaking. But visualgc allowed for a real feel for how the generational GC was running just by watching the saw-tooth shaped graphs. Interestingly most of the garbage was string copying, especially with one companies system that had more abstractions than a Spring Oak has leaves, say no more least I have nightmares.
