With a proper low-pass filter, the RF will be fine. I have a "WSPR" beacon going all the time that is heard around the world -- from Antarctica to Europe to Japan to Russia. The RF is generated from an I/O pin, low-pass filtered, and amplified to 200mw which is a common power level for WSPR.
Not saying you should change, but if they aren't engaged deeply, then that sounds like the freedom to do whatever and get paid for it.

> Do you know any prominent physicists that hold that view?

The view that the entropy of a microstate (i.e. a perfectly defined physical state) is zero?

All of them, hopefully.
> I don't know what Entropy is supposed to mean on the level of individual states/configurations. I don't understand what kind of macroscopic "averaging" function we may use to group up those states

I find it helpful to think of entropy as a property of not of the system, or any individual state (micro- or macro-), but as a property of the "compression" process that summarizes microstates with a coarser-grained macro-description.

Given a choice of compression, classical physics says a system will tend to spent most of their time in the most likely compressed state. Different choices of compressions can lead to different macro descriptions, with different "entropies" and different dynamics among their macroscopic variables.

In this light it's not meaningful to think of the entropy of individual states. You could think about the "identity" compression, but you would end up with a description that was exactly as complicated as the full micro-state time-evolution dynamics; you wouldn't end up with any smaller set of variables that could describe the equilibrium of the whole system (really this would not admit an "equilibrium" at all)

What happens when food is scarce and people are starving for possibly the first time in their life? Anxiety, depression, etc is well established.

Then people are going to want to know why they are starving.
The point is pedagogical. Entropy takes a lot of time for people to understand clearly. That is the discussion from the OP.

Adding "knowlege" to the definition (or to an initial explanation) of entropy makes that learning process even more difficult. And it's unnecessary. It's better than the older talk about "disorder" but it's distracting. We can bypass 'knowledge' and come back later, with no penalty and plenty of time savings.

Apart from that single pedagogical point, we seem to be saying the same things back and forth to each other in different words. I'm not sure why.
In short, Hackerrank people have no common sense and decided to take down content that looked like solutions to Hackerrank problems.

If every action in a cloud service had to be instantly billable, it would just about double the complexity and cost of every operation. For example, fetching a blob from S3 would also need to insert the read activity into some realtime billing database AND check if you've exceeded budget. This ends up coupling everything into your billing system and makes the billing system much more active.

Instead what cloud providers do is cheaply write an activity log to some async queue system. Eventually (hours later) those logs get aggregated into a central location and a bulk usage levels get updated onto your account. This is much cheaper to do and keeps everything decoupled.

This submission came up because the article author is on twitter today complaining about golang and posted the submission link.
This is horse radish. There is an argument that NATO expansion drove Russia away from the rest of Europe, maybe it was also US engagement in Ukraine which was misunderstood or perhaps not. Perhaps there are domestic forces pushing Russia to war, but it was certainly not Merkel and her policies. Germany was an escalating factor in the conflict between western nations and Russia. That has evaporated now of course and I don't really see how this conflict could end until Putin says he had enough.

I hope Kaczynski and Zelensky have a significantly better judgement of the political realities in Europe if they believe Merkels decision on the point of nuclear energy is in any way relevant. Their countries have to build a relationship with Russia at some point.

Furthermore the article completely neglects the economic realities of nuclear power and downplays possible danger. I think it was this or last year the first permanent storage went online, either Finland or Sweden. Would have to check if it really happened or additional problems surfaced.

There is also a dependence on Uranium as fuel. Could ask Putin for that too. Sure maybe Canada could help out. I think more political experience and restraint could have prevented a war. Was Putin justified to invade Ukraine? Certainly not.

U.S. Economy Shrinks in First Quarter of 2022
My Anecdotal Experience:

Golang is great for spinning up new services and tools with very little overhead, the language is well designed for the backend - and the lack of <insert programming language feature here> avoids "odd" decisions which other engineers will dislike in the future. If your job is building lots of new things using relatively common building blocks, then Golang looks fantastic!

However on mature services, engineers often need <insert programming language here> because they are dealing with something extremely complex. The author of this blog post digs into the scenario for a package which needs to support different non-nix operating systems, but the same can be true of an app which has to manage many different kinds of objects (Kubernetes, or any service with many DAOs). Alternately there are engineers building all kinds of weird software which may do new things in novel simplified ways. Golang occasionally makes expressing these types of applications more difficult.

Overall I enjoyed my time writing go, until I tried to write a statistics based application for a startup idea back in 2016. The project didn't get very far, and that was partly due to me getting bored having to deal with all of the different numeric data types, at the time the lack of generics made it so that you either had to use reflection - or implement the same function N times over to support the different numeric data types. This tedium killed my love of the language (I'm sure it's a better experience in 2022).
Assuming that you can trust the "smart contracts". And I think there's a lot of reasons why such trust is not warranted.
Learned electronics in university, but definitely was able to work on projects in a small apartment later on. Had a small box of electronics stuff that can get put away.

Arduino or various other microcontrollers, multimeter, breadboard, and a bunch of small parts (resistors, capacitors, ICs, LEDs, sensors, wires, etc). Having "lab" gear like an oscilloscope, signal generator is definitely nice but not needed to get started

I do use Raspberry Pi 400 for accessing other machines via SSH and browser. Lack of memory really limits being able to replace a lot of desktop workflows, so I still do most of my work on a i7 powered LG Gram 17 that runs Kubuntu. The Pi is significantly slower than four year old i5 MBP and way slower than the i7 for building node apps and compiling Go... but, it's fast enough it could be usable. I do love the keyboard form factor. It is a pretty impressive device for the price, and has this old-school "home computer" vibe to it.

> how does one identify things that they could be good at?

Being "good at" things isn't the problem. I bet you're good at many things! But it sounds like everyone around you is also good at those things.

Looks like you've identified the two possible solutions: 1) become good at something that sets you apart, or 2) surround yourself with people who don't have your skillset (ie, new career path.) I don't know enough about you to make a good suggestion for new career paths, so I'll focus on the "new skill" angle.

To develop valuable skills, follow the pain. Every team has things they hate to deal with. Find those things. Learn how to make them less painful. If you can find pleasure in the difficulties of the painful thing, that's ideal. If not, you can at least take pleasure in the fact that your coworkers will love you for saving them from the pain.

Then you'll have an easier time getting new jobs. You can walk in and say, "I'm good at that thing your team hates dealing with." It's not enough to get you hired every time, but it sets you apart.
Whatever sets your soul on fire. For me it's coding. I got into coding before it was cool to have a dev job and have the upper-hand and can out-compete anyone learning it just so they can get a job. For me it came naturally and it wasn't forced. I didn't do courses or anything. Autodidact.
The administrative side typically doesn't actually understand the technicality of administrating care and many times are MBA business types who administer a business as if its is commodity without understanding the true nature of the business (from their overconfidence generated from their degree and their lack of understanding the nature of the problems through distillation and non-technical understanding). This MBA culture is similar to tech/prod relationship in tech companies. Thus they provide little value add and get paid unfair amounts for their relative value.

I agree that Doctors and Nurses would likely be poor administrators - however the disparity in income is incomprehensible in healthcare.

Nothing wrong with having a multi-GB HashMap or something that you have to load into RAM in startup. It just depends what you're doing. It's certainly cheaper than recomputing that HashMap.
Painful situation you are in.

This seems like you have an idea that will generate money in the pocket of others.
But in the world we live in, value is completely disconnected from extracting money from it.

The only thing that matter is whether you are in the position where you can extract it.

These sort of "multiplier" add-ons ideas that 2x your revenue is great if your revenue is already 1M, but worthless is your revenue is 1k. All companies run on them, often generated by employees that only get a fixed amount for them.

If you have idea can generate enough of a competitive advantage, and difficult enough to replicate because it doesn't mesh well with current competitors and they would need a complete rewrite, then you have a niche you can specialize in, and to convince an investor you just show your competitors market value say you'll get x% of it if you have the resources to get over the entry barrier of re-implementing everything your competitors have but compatible the addition of your shiny idea. Depending on the equations it will be deemed economically feasible or not.

If the idea is easy to replicate by your competitors, well it's like in Go, where you play a stone inside the territory of the enemy that is immediately captured, you just wasted a move.

Often ideas that are not implemented can be for reasons that you don't perceive as an actor outside the industry, or it can be that it's already in your competitor territory and they have more pressing things to do.

Depending on your relative sizes, some times a partnership can be struck, or you can join them as an employee if you enjoy working in their solution space.

Some times these ideas are best kept dormant, waiting for a better time for them to flourish. For example once you have acquired enough reputation based on previous success, that you can get investors to invest in you rather than in your ideas.

Other times these ideas end-up in an open-source project where they contribute to lower the entry barrier that will make some economical equations more easy to solve.

But the most likely scenario, the default if you choose to do nothing, is that 5-10 years later, your would have been competitors will implement something that would look like what you have in mind and make a ton of money with it. But to help soften the blow you will remember that this value wasn't ever yours to begin with.
Shadowbanning is big tech’s big problem
It can be related to compression. If some phrase has a probability p_i of occuring, then the optimal length for the code is -log(p_i). The entropy sum(-p_i log_pi) = mean(-log(p_i)) is how long code you will use on average.
Refinance applications were down 70% compared to year ago. Combined with low home inventory, the mortgage industry looks pretty grim.

Interesting! I love everything about how and why the piano came to be.

Without numbers on the widths, it's hard for me to grok the article... but I can tell from looking down at my synth that E is the big fattie and has a much wider section between the black keys. You can also stick your finger in there and feel that A is thinner than E, and it feels to me like G is thinner even than A. This is on a Roland V-Synth. It seems like manufacturers can solve this however they want? Is one way predominant?
Thank you for your comment. I think this is interesting:

"Higher rates will make current prices unsustainable. As soon as they correct to the point where monthly payments are back to what they were last year, there will be buyers, only too happy to overextend themselves to get out of renting."

So, higher rates are effectively a transfer of wealth from homeowners to banks? How does this serve to combat the current inflation issue?

If you don't do a full screen refresh you can get 10Hz refresh rates on newer products. The quality is similar to the newspapers of yesteryear.
The beauty of JAMStack in my opinion is that everything is pre-rendered at build time, so your site is 100% static and can be served out of a CDN.

Pair that with third party APIs or a serverless backend like Firebase and you basically have an infinitely scalable dynamic website for little effort.
Usually that's modeled in the application layer. In scuttlebutt you'd store a higher-level state as one of the node-specific parameters. The gossip protocol doesn't need to know that you know the node knows it's about to die, though there are optimizations to be made there.

Despite what the sibling commenter claims, in a production system you absolutely need that distinction -- not in terms of the reliability of the low-level protocol, but in terms of the application features you want to expose. A node about to be removed needs a chance to drain active connections.

How much of that was due to inflation? Remember these numbers are nominal GDP. So if price levels doubled and nothing else changed, GDP would more or less double as consumption went up due to higher prices.

The worrying thing is there are no monetary levers available without the risk of higher inflation. And if people don't think GDP matters, its actually a very good indicator of all sorts of well being measures such as unemployment and premature deaths among other things

[EDIT] This is real GDP. I was mistaken
Browser engines need a lot of computing to know what color each pixel of a page needs to be, for each pixel: the typeface affects it, the background image of all the parent elements (in case of transparency) affects it, the CSS positioning of the elements affects it (there could be a white title text, but an annoying cookie popup with a semi-dark background means it needs to be displayed as a greyed out text).

All of the predictions ahead of this number and the article itself were predicting this based on inventory surpluses that had been built up in the previous 2 quarters. That seems a more directly attributable cause than fears of interest rate increases. In fact, if you anticipate interest rate increases it makes more sense to bring spending forward not to delay it.
I think they are niche because they have a much worse reflectivity (and hence contrast) than usual monochromatic displays. The existing approaches use sub-pixels to create color via additive color mixing. This approach throws away roughly two thirds of the incoming light. E.g. a red pixel consists of red+black+black sub-pixels.
People have long been fascinated with "alternative" architectures for general purpose computing but most of the time you pay a little bit less (1/2) but pay dearly in terms of performance (more than 1/5 compared to a low end laptop.)

It has a lot to do with why cable boxes suck.

ARM is the first architecture in 20 years that competes with x86 on reasonably priced machines. (e.g. IBM POWER and IBM z are pretty quick but you can't afford them)
