Greetings! I'm a full-stack developer with over 10 years of professional expertise in the C# .NET stack. I'm available for both part-time and full-time contract work, with a preference for long-term commitments. From DevOps and CI/CD to Terraform, AWS, Azure, Digital Ocean, and React for the front-end part, I have years of hands-on experience with every aspect of the projects.
My work hours are flexible, aligning with the USA time zone. Check out my CV on Toptal and my website for more details. Usually my rate is about $90/hour.
Some of the wording here is awful. Like:

"Following a disciplined approach"

Were you not doing that before? If not, why switch now? What's the actual difference. Seems like a weird thing to say if it doesn't mean anything. It's like you're trying to boost the word count.

It's not even this particular line, it's just the whole post feels like it was written for the sake of a blog post, and not much else. It puts me off reading more.
They probably did.

The Pytthon standard lib calls out to hand optimized assembly language versions of the crypto algos. It is of no relevance to a JIT-vs-interpreted debate.
Ofc it's still true, as long as you don't take it too literally ...

Essentially it means it's gonna take a whole lot of practice and repetition for your brain to build the necessary neural links and reinforce them by forming a proper amount of socalled Myelin [0] so that they fire faster, more effectively and more efficiently than ever before.

And it doesn't matter what kind of skill you are talking about - be it physical or mental, eventually it boils down to the neurons in your brain.

If anybody happens to be into the current Age of Empires II scene, this [1] is what 10000 hours of practice gets you there for example (the guy has been the World #1 for a good while now).

It's better for the environment as well, because you're not throwing the whole thing out/leaving it to the whim of whoever is supposed to recycle it, plus you can selective change components that are bothering you - keyboard, mouse etc.

I switched to Bluetooth earbuds way back in 2007 when they were still novel (Sony Ericsson HBH-DS980 represent - with an LCD screen for switching between paired devices!). When I use wired headphones they get caught on door handles etc and have a lifespan of like 6 months before they get torn apart.

I still use wired (with a dongle) for calls, since Bluetooth Headset profile sounds like crap and I have enough trouble understanding people/being understood as it is. MagSafe helps with charging when the port is in use.
You should contact Boeing with that information, I'm sure they'll find it invaluable.

You need a very diverse community to address these subjects. HN is IT-centered, there’s overlap with a lot of fields and occasionally you’ll get a (few) people who are at home with the subject at hand to explain the subtle intricacies.

But this also relies on the size of the HN populations. Too many and the noise takes over, making it difficult or even frustrating to participate.

Stick to what you know and plough on.
Sorry my statement should have been moderated: "In EU most countries have institutions with insignificant tuition costs"
Did you already know what a JIT was before reading the article though? Confirming what you already know is a different thing than grokking it the first time. Plus in my brief but intense experience as someone teaching programming to artistic types who are scared of maths, it's more useful to evaluate explanations by the possibility of being misunderstood and overwhelming, than the possibility of correctly interpreting it.
When I read it, your comment was invisible to most users and at the bottom of the page. Flagging is done by other users who are offended at what you say (presumably by the 'experts' who dismiss an experimental prototype aircraft because the new tech doesn't make sense for quadcopters..)
> I wonder where the US would be if we had focused on manufacturing growth instead of offshoring production.

Probably poorer for one. Every American working in a state-subsidised manufacturing role is one less American working in an industry where the US has a competitive advantage, like software or energy production.

Of course if war breaks out that goes out the window.
Concorde ? maybe? it literally changed the industry online to be cancelled later
None of them exist in my country but we do have Wolt. I'm sure there are plenty of places around the world that don't have any service like this.
"Rural" Netherlands is still pretty dense, though. At least dense enough that the very idea of getting from one place to the next by bike is pretty sensible. You don't have that in the true rural U.S. Now suburbia could look like that (i.e. village-like mixed use communities linked by bike paths, not just vehicular traffic) and that would be a better comparison.
yes, that is true. but aot compilers never make things slower than interpretation, and they can afford more expensive optimizations

also, even mature jit compilers often only make limited improvements; jython has been stuck at near-parity with cpython's terrible performance for decades, for example, and while v8 was an enormous improvement over old spidermonkey and squirrelfish, after 15 years it's still stuck almost an order of magnitude slower than c https://benchmarksgame-team.pages.debian.net/benchmarksgame/... which is (handwaving) like maybe a factor of 2 or 3 slower than self

typically when i can get something to work using numpy it's only about a factor of 5 slower than optimized c, purely interpretively, which is competitive with v8 in many cases. luajit, by contrast, is goddam alien technology from the future

with respect to your int×int example, if an int×int specialization is actually vastly superior, for example because the operation you're applying is something like + or *, an aot compiler can also insert the guard and inline the single-instruction implementation, and it can also do extensive inlining and even specialization (though that's rare in aots and common in jits). it can insert the guards because if your monomorphic sends of + are always sending + to a rational instance or something, the performance gain from eliminating megamorphic dispatch is comparatively slight, and the performance loss from inserting a static hardcoded guess of integer math before the megamorphic dispatch is also comparatively slight, though nonzero

this can fall down, of course, when your arithmetic operations are polymorphic over integer and floating-point, or over different types of integers; but it often works far better than it has any right to. in most code, most arithmetic and ordered comparison is integers, most array indexing is arrays, most conditionals are on booleans (and smalltalk actually hardcodes that in its bytecode compiler). this depends somewhat on your language design, of course; python using the same operator for indexing dicts, lists, and even strings hurts it here

meanwhile, back in the stop-hitting-yourself-why-are-you-hitting-yourself department, fucking cpython is allocating its integers on the heap and motherfucking reference-counting them
languages don’t need to all be good at the same thing. Python currently excels as a glue language you use to write drivers for modules written in lower-level languages, which is a niche that (afaik) nobody else seems to fill right now.

While I’m all for making Python itself faster, it would be a shame to lose the glue language par excellence.
Google Authenticator is just a TOTP client. You can just copy the token to any app. I'd personally recommend KeePassXC.
>A personal site is a lonely place. That's why blogs, after an initial burst of creative energy, languish. People nowadays seeking online to fulfil their social inclinations go elsewhere, to the platforms better optimised to harness that social energy.

A personal site or blog might be a lonely place in the early days but then came comments section and people started discussing your articles but then came the question of persistence of your profile and I think Disqus is a pretty good web commenting solution to that regard.

The biggest problem of big social platforms is content discovery; there is so much content out there that you can not find the content that suits you the best. That's why you see "Discover" feature in every app because they became aware of that problem. That's also why TikTok took off so wildly because they glued together short attention content (short videos) with powerful recommendation system.

Like somebody already said, web and social platforms push only new content to you, they are sort of like TVs but there is vast amount of content and websites that are never discovered and visited because the right incentives aren't there to show you old content and old websites.

Heating has strong 'follow the crowd' effects: the cost of different options are heavily influenced by what's already commonly used in the local area, because the supply chain will be optimised, and local workers will be most familiar with what's most popular. Bucking the trend in any way sets you up for higher hardware costs and much higher installations and maintenance costs, even if in a different country the same option would be the most economical. (I have experienced the same pain, in a country where most heating is plumbing and radiator based, having a house set up for central air heating and wanting a replacement for the central unit, it was almost the same cost to replace that central unit as it was to rip out the whole thing and replace it with radiators, which is ridiculous on the face of it but a consequence of the supply of parts and labor for each option).
No? Being a mediocre hiker is perfectly adequate for a joyful day out with friends. Being a mediocre cook is sufficient for adding joy to your meals. Being a mediocre singer is enough to be a joyful and contributing member of a church choir.

Thinking expertise is required to enjoy things definitely can blind you to the joy that can be found in mediocrity.
They can also be crazy silent, I have one at my place I just installed, it's "air based" it's ridiculously quiet.

Ask HN: Be honest, how often do you reject good candidates for cultural reasons?
I am not asking only out of personal reasons, rather I have heard from enough others similar experience that I am prompted to ask:

How often do employers truly reject good or even great applicants simply out of cultural reasons?

It seems to me that even if your expertise couldn't fit the job advertisment any better, if you simply ... look different and have a too different sounding name, there is a high chance you are gonna get declined.

I am not asking to shame, but rather I could imagine it being a legitimate point of concern for employers to think "this guy is great but I fear he is not gonna fit into our team culturally speaking".

So I just wnat to know how common it is.
If I understand the comment you’re replying to, the loss is the competitive advantage.

I.e., if a desire for static types was keeping a large number of devs away, then this development will lead to far more devs using Elixir. This would erode some of throwaway_64000’s competitive edge as those devs also got the productivity gains of using Elixir.
It's fun to think about theoretically more efficient methods of heating.

1) Heat pump - you use electricity to move heat from the outside in. It has efficiency over 100%, because you get all of the electricity's energy, plus some of the outside heat.

2) But generating electricity at the power plant uses heat in the first place, and wastes a lot of it. Let's bring the fuel to the house and make a heat-driven heat pump. This way you get 100% of the fuel's heat, plus heat from outside.

3) But this is still wasteful, because fuel burns hotter than the temperature you want in your house. So you could generate some electricity along the way, and use it to power domestic appliances. This way it will do useful work, and then 100% of it will also end up heating the house, because there's nowhere else for the energy to go.

4) And even that is still wasteful. The house is too hot in summer, and during the day, and too cold in winter, and during the night. A large enough heat reservoir, like thick walls, can smooth out this variation and give you average temperature all the time.

5) And believe it or not, even that is still wasteful. The human body produces enough heat to be warm in most temperatures, given good insulation. So we go from needing thick walls to needing thick clothes, which are much cheaper.

6) And even that is still wasteful! Because you don't need thick clothes either. So we arrive at the perfect solution for staying warm: a pill that makes your body heat up without fuss when it's cold, and lose weight along the way. Combine with clothes to taste.
I don’t know Pyjion, but I have used Numba for real work. It’s a great package and can lead to massive speed-ups.

However, last time I used it, it (1) didn’t work with many third-party libraries (e.g. SciPy was important for me), and (2) didn’t work with object-oriented code (all your @njit code had to be wrapped in functions without classes). Those two has limited for which projects I could adopt Numba in practice, despite loving it in the cases it worked.

I don’t know what limitations the built-in Python JIT has, but hopefully it might be a more general JIT that works for all Python code.
There is a funny thing about occupation in the eyes of the international law. For example Armenians have always lived in Nagorno-Karabakh, this is their ancestors land, but according to the international law they were occupying the territory of Azerbaijan because one genocidal dictator assigned that territory once to Azerbaijan. Now they have been abolished from their land with no real perspective to return. But according to the international law everything is alright.
Personally I never particularly liked wired headphones because of the annoyance of dealing with the wire and it breaking any time it got snagged. My Bluetooth ones last for ages without charging so it's not a big deal to charge them. Since they're pretty cheap now I think a lot of people are the same way.

People love to complain about the dongle but really it just adds a couple of inches to the wire. If you can deal with the wire you can deal with a wire with USB-C on the end.

In the US, it’s more common to have 1 or 2 large units pumping into ducts in every room of the house.

Much better link to the full text of the actual replication study, without the vox-splaining: https://royalsocietypublishing.org/doi/10.1098/rsos.190327

From the abstract: “Overall, the size of the effect was substantial, but considerably smaller than the original study's effect size.”

Regarding small sample sizes: “
The current sample was obtained from over 4 years of recruiting efforts (summer of 2014–autumn of 2018). While our sample size is 33% larger than Ericsson et al.'s, it is still small. Conducting expertise research, by definition, means studying a small subset of the population, thus there are relatively few participants from which to sample, making large-sample replications nearly impossible. However, if replications of expertise studies never enter the scientific record because of small samples, then we probably will never provide additional evidence to support or refute the original studies. This leaves only the original study (with an even smaller sample size) as the only indicator in the scientific record.”

“To be clear, evidence from small samples—in original studies or replications—should be interpreted with caution. However, when the original study (with a small sample) has already entered the scientific record, replications with similar sample sizes (since that is all that is feasible) should also be allowed to enter the scientific record rather than be suppressed from publication. This is probably the best way to accumulate knowledge in this area.
”

Oooo! And they link to actual data they collected in the study! https://osf.io/4595q/

Only part of this your body doesn't automatically do on its own is the "without fuss" bit. And that part can be trained.
i thought about that but you also have to port the apps, many of which use self-modifying code, which flash program memory is not enthusiastic about
I think it is perfectly fine as long as it is a deliberate decision. But lines are blurry between deliberate decisions and just trying to push back the next difficult step.

There's a lot of effort going on to improve CPython performance, with optimization tiers, etc. It seems the JIT is how at least part of that effort will materialize: https://github.com/python/cpython/issues/113710

> We're getting a JIT. Now it's time to optimize the traces to pass them to the JIT.
Agreed with caveats. A good general robot would still probably have similar mass to a human, appendages with similar reach, and so on. A horse carriage and a modern car have similar sizes, can take similar amounts of cargo and seating, and take up similar space on the road.

So a good generic bot needn’t be an android, but in that ballpark.
The big cost is the upfront cost of insulation and removal the existing heating systems.

Speaking about the UK (article is mostly about he US which will have their own problems), we have very poor quality housing stock with effectively zero insulation. You hold your hand to the exterior walls of your typical 2-3 bedroom terrace house (the most common type of home in the UK) in the winter and its just ice cold. For these homes the exterior wall are just solid brick and plaster with no air gaps. Many homes still don't have double glazing and their windows bleed even more heat. These homes go cold quickly when you turn off a gas boiler, and a heat pump just cannot keep up with the heat loss.

In addition large numbers of households in the UK have migrated to "combiboilers" heating systems that dispensed with hot water tanks for on demand hot water from their gas boiler. In the process many of these properties have converted the space previously designated for hot water storage to loft extensions or other home upgrades. UK homes are pretty small, and going to a heat pump system means going back to hot water storage, which most UK homes have no space for without costly changes to the home layout/structure potentially including sacrificing parts of precious loft conversions.

Frankly we might be better off just knocking down and rebuilding some of our housing stock at higher densities such is the cost of retrofitting and our housing shortages, but there is no political appetite in the UK for any radical solutions like that.

I'm building a new house and I'm based in Poland. I'm going with air heat-pump* + a simplest fireplace as a backup - not connected to central heating, no electronics. On top of that 10-20kW of solar and a place for batteries. I'll install them once they get cheaper. The house is 200m^2, so I'm hoping to pull only 200 kW/month from the grid and generate rest on my own.

Also, I've been wondering how much efficiency would I get if I could put some mirror and direct the light to the unit in the winter. It could help with defrosting as well.

*I was considering horizontal heat pump, but it's not worth it. It affects vegetation and future construction.
