It isn't. The bird is between the sea and the jet and for all practically purposes stationary. When the camera pod on the jet tracks the bird and keeps it in the center of the field of view, what you are seeing is a parallax motion of the sea in the background due to the motion of the jet.

Your comment is needlessly rude. Soma Rush, Surly Steamroller, All-City Big Block, Wabi Special (other steel-frame fixies) are all around 20 lbs flat -- far, far less than 28-29 lbs. Slightly higher end track bikes weigh even less. This thing is a bad idea, even if its weight was reasonable. I dispute that its weight is reasonable, but that is not the only problem with the bike.
I don’t know for sure about the memory and cpu rationing but doesn’t systemd expose the rest of those limits for service units?
User Friendly was the first big web-comic, the first to establish the idea of a web-comic as a primary medium, as opposed to being adapted from another source (newspapers) or intellectual property. It started in 1997 which was really early in Internet time, around the peak of the dial-up era (and the setting is a workplace of a dial-up ISP.) It may not have quite been the first web-comic, but it was the one that first reached a critical mass of general notability in geek culture.
We counter this by giving applicants a small homework problem and ask them to solve it in the language of their choice. Then we have tech interview centered around their solution. We'd know in about a minute if someone else did the did the thinking for them. It's also a good jumping off point for all kinds of deeper questions, systems knowledge, engineering practices, wherever we need to go.

> That is better that almost any other heating source

... if you don't charge generation and transmission inefficiencies against it. High efficiency natural gas heating systems are 98% efficient; compare to natural gas combined cycle plants that are ~60% efficient, plus a few percent more lost to transmission and distribution.

> with exception of heat pumps

Sure, that's the actually-efficient source of heat from electricity.

> For light bulb, i guess most energy is dissipated by IR radiation and only small part by convection.

For incandescent bulbs, this is unrealistic. The bulb is quite hot and heats the air around it and the fixture.

Moreover, of the IR, a whole lot also strikes the fixture and is conducted into the ceiling.

This is true. When I started my first job, I tried casually learning more from where I stopped after I finished school. My motivation slowly waned as I realized I vastly preferred playing video games than watching lectures and trying to do some problem sets.
I usually use a 'what are either side saying about it' and then apply a 'there are always three sides to things <side A's, side B's' and the true event>' heuristic transform filter.

My opinion is, let all the information flow. People are not sheep that need herding by the powers that be (again, I refer to both 'sides' here).
Services that automate the interviewing or vetting process benefit the hiring manager, but feel impersonal and disrespectful to candidates. (Isn't my time valuable too?)

How do you know that exactly?
Correct me if I’m wrong, but I assume you’re looking at this through the wrong lens. As a PhD you’ve learnt something hard at a considerable depth but this isn’t what I, or most people, hope to achieve by learning maths themselves. It’s normally to a far lower depth that’s far more achievable like Calculus I or some aspects of number theory or knowing what all the funky symbols such as Summation mean.

I think to some extent it's a frame of mind thing. For instance, my friend's vacuum broke for some reason or another, some plastic piece that wasn't super complicated, but was required for functionality. And rather than buying a new one, he was able to model and print the piece that broke and the vacuum is able to work again, but mileage in general probably varies.

That's basically the BTC approach and it shows. Stable, but significantly more slower dev ecosystem. ETH, and by extension web3/defi are a result of builder/hacker types leaving BTC to get something more dev/app friendly.

Some cheap lipo cells can get you a sweet 60-120C discharge rate with a pretty okay capacity. They are also widely available on the used market, usually sourced from EV batteries or energy storage packs.

Some questions about computer architectures
Hi. Sorry for bad English, i'm from Germany. I'm developing my own instruction set architecture. I wanna ask advanced developers about possible pitfalls like slowdown or increased heat dissipation etc. in relation to arch described lower.
So, the main properties is: my instruction set uses SWAR approach - long common register, 256 bit wide, data is packed into bunches up to register width, and for every register-register instructions (except logical and bit twiddling) there are 4 different versions of them - 16, 32, 64 and 128 bits per unit of data, and so, 16/8/4/2 units per bunch. (It's not necessary to fill the registers completely, each register-register operation works "separately", so, you just ignore higher bits, use only lower and later extract it as you need). Also, it's VLIW architecture - instructions itself are packed into bunches 256 bit wide. But here's the problem: instruction length is not fixed. (Also remember that in VLIW there are frequent NOP's, and it's big waste of memory).
The problem of data density is easy to solve - in my ISA there're also load/store instructions that loads or stores only small amounts of data (16, 32, 64 or 128 bit) instead of manipulating full bunches. But if i use the same approach to instruction bunches, i will need to introduce fetch meta-instructions. So, i came up with a different approach.
Firstly, 256 bits are loaded into instruction register, starting at the address specified in the instruction pointer. First 4 bits of instruction bunch mean the amount of instructions in it. Next comes the opcode, based on which the length of instruction (with all registers/addresses/immediates) is computed. It repeat as many times as indicated in the first 4 bits of bunch. Other bits are ignored. After that, the instruction pointer increments to amount that is calculated from readed instructions, plus alignment. Bunches are aligned to fit into 16-bit memory cells. (My ISA uses 16 bit cells instead of 8).
My main questions: Wouldn't decoder be too complicated? Will it dissipate too much energy or not? What are the pitfalls regarding jump/interrupt instructions? And what do you personally think about this idea?
> We found that the more a firm responded to complaints, the more likely it was to fall in both value and in perceived brand quality

I'd bet large sums of money the habits of customer support twitter accounts have zero effect on market cap (lol) or perceived brand quality among the general public (not enough people use twitter and pay attention to brand account behaviors to effect this metric)
Are you planning to create tech management interview cases? They don't seem to be as qualified as the people they hire. Seems like a problem in need of better application screening processes.
Geometry has really all that is needed for proofs:

* Axioms

* Substitution

* Modus Ponens

* Universal Quantification

Induction or proof by contradiction are just special cases of this.

But yeah, geometry for introducing proofs is difficult, because it is so easy to confuse visual intuition with proof. At the very least, you need a capable teacher who knows the difference. But nobody expects children to understand it all from the get go. A healthy struggle to disentangle intuition and proof, and then to entangle them again later on once you know the difference, that's the path to understanding mathematics.
I have personally seen that a lot of "cheap" point to multipoint contended access VSAT modems have very little security on them.

Would not be surprised in the slightest if something like a new firmware load or configuration push coming from the hub of the network was not properly validated by the modems using a secure crypto key/signature method.

Keep in mind that what we're talking about here is the European equivalent of the viasat/hughesnet/wildblue low cost, highly contended access geostationary vsat modem service. It's about the cheapest possible thing you can buy that is two way IP data via geostationary at 64:1 oversubscription ratio or more. There are very demanding economics factors in play that require the company to make the end user terminal hardware as absolutely cheap as possible, for all of the sub components (physical dish/mounting, LNB, Tx/BUC/SSPA, cabling, and modem).
> it's still sitting below user space and can do whatever it wants to the system.

I don't know much about the Endpoint Security extension, but for Apple's network filtering extension they actually DO address this!

The code that runs on every network call is heavily sandboxed and can't communicate at all with the outside. Its only action is emitting some basic signal like "block" or "accept". This means that while the system extension can evaluate all your network communication, and block what it chooses, it can't exfiltrate the specific content. I might have the details wrong, but that's the general intention.

But the security benefits aside, I think the real reason for preventing code from running in the kernel is about stability and not security. Buggy code won't crash the system anymore. They can also enforce stricter performance requirements.

(And at the moment, you can still run kernel extensions on your own system if you really want by disabling SIP and other things, it's just infeasible for any AV vendor to have their customers step through that very onerous process.)
The problem is once again our godawful prior government. Many tens of thousands of jobs in the wind industry have vanished over the last years [1] because the Conservatives oppose renewable power and impeded it wherever possible - if it is because of corruption, incompetence, fear of the far-right that outright demonizes anything not fossil or nuclear I don't know. In any case, we simply don't have the staff to visit literally thousands of wind turbines, a lot of which are actually offshore, simply to replace routers.

This situation is an unbelievable clusterfuck.

> Why would Russia want to start with extremely costly urban combat when the ukrainian forces are still a coherent fighting force?

Did you not pay attention to the first weekend of fighting? Your analysis is correct but the Russians did try to take the 2 largest cities right away. There's massive wrecked convoys outside both Kyiv and Kharkiv.

And it was extremely costly. And now the Russians look extremely weak.

And now they're slowly making progress doing what you think they should to win. And they will win if the Russian oligarchs and military support them until the end. But that last point is a huge question mark.
Agreed. Dilbert was for if you worked in an office building doing pretty much anything. User Friendly was for a very specific niche of people who either worked at mid-sized ISPs (like MandieD wrote: https://news.ycombinator.com/item?id=30593421) or who supporter or empathized with people who worked at mid-sized ISPs.

> I agree it seems weird to call close to 100% efficient "terribly inefficient"

A lot of my winter and nighttime electricity comes from natural gas.

50-60% of the heat energy in natural gas can get turned into electricity and make it to my house.

Then, it can be used to heat my ceiling a light bulb, where almost half of the heat immediately escapes my home. This is not a very good way to heat my house, versus my high-efficiency natural gas central air system that is more than 95% efficient in using the energy in natural gas to heat my home: it's about 3x worse.

Of course, even more efficient would be to use the natural gas to make electric power that runs a heat pump. That could be 200% efficient end-to-end.
It's as if the best you can do is delay the inevitable (which could also be re-phrased as "flatten the curve").
There's also the lifecycle cost of the fuel and the power station itself to account for. This is higher for nuclear than for solar/wind.

quickly fixed and a lesson learned!
Yeah so this is a common concern we've seen. "How do I know your idea of a senior engineer is the same as my idea of a senior engineer?" And the answer is you don't. We're modifying the report to no longer say things like "Strong Junior dev" but rather to just give you a bunch of raw data, and then you decide how that data is interpreted.

Some examples:

1. 7/10 unit tests passed

2. GET:/api/v1/vehicle/{id} OOM'd out at 1.5M records in the DB

3. Linter returned 10 warnings, 0 errors

4. Cyclomatic complexity counter returned max of 24

5. 5 new commits, shortest commit message 3 chars, longest commit message 45 chars

Also, the concern with outsourcing to a cheap contractor is a very legitimate concern, because we ALMOST actually did that. Instead, we decided that it was a bad move and to double down on building product + surfacing clear, unambiguous data. That's also why we're intentionally staying away from ML (at least for now), because it's inherently unpredictable.

Polio has no treatment, but good physiotherapy may help with recovery. The small number of people who get paralysis need to go to hospital and may need intensive care. Some people will need long-term treatment for limb paralysis.
This gives me a chance to ask about a different webcomic that I read in the early 2000s, but have totally forgotten. It also took place at a small development company or ISP. There was a dog who was a system administrator, and he might have been in love with a cat? All the characters were animals, I think, and there were the usual 90s-early 00s Linux/Microsoft jokes.
Why now? I think there hasn't been any fresh non-forum content on the site for at least 12 years. Just didn't feel like paying hosting costs, or something else?
They know their lavish lifestyles are not long for this world. I'm guessing they believe the Russian government cannot touch them, or they feel that "poverty" is worse than the consequences of defiance.
This is a very interesting approach, I’ve seen some competitors who do this in the learning/course space as well. I’ve also done a lot of interviews from both sides of the table.

My question is around the grading examples. How do you automatically determine Functionality is Senior - Weak or Commit History is Intermediate - Strong?

I find these to be quite subjective and better understood as a whole for any given candidate. The grading mechanism provides a false sense of being unbiased, and further dehumanizes the process.

> Every metric we measure is numeric, and every test is deterministic. As a result, you can make hiring decisions based purely on merit.

I fully disagree with this for hiring, unless you’re looking for machines, not humans. Measuring things automatically does not result in purity of bias.

That's not 'entirely different' from 'a bunch of yokels playing king-of-the-hill with the capitol building,' that's the intended result of 'a bunch of yokels playing king-of-the-hill with the capitol building.'

I really don't understand the point you're making here.
Bases are getting much smaller; there are fewer registered D/R vs independents.

This makes the “swingable middle” rather large, and they’re not all rubes.

> Web scraping is most certainly legal. Everything involved in the ridiculous "breaking and entering an unlocked residential door" is done a billion times a day by web scrapers as a matter of course

Unfortunately you, like others, are ignoring the crucial element of consent. Web scraping is done lawfully only with the consent of the website scraped. When scraping is done non-consensually -- even if the website is public -- it can be considered trespass to chattels and might even constitute a CFAA violation. I know this because my company scraped eBay without their consent in the late 1990s/early 2000s and was shut down by a lawsuit. See, e.g., eBay v. Bidder's Edge, 100 F. Supp. 2d 1058 (N.D. Cal. 2000) (not my specific employer at the time, but in the same business).

Ignore robots.txt at your peril, and treat the absence of one as a lack of consent. That's what Google and other search engines do.

> That is you have a "debate" in high school where you have to fight hard to defend a position that you don't personally believe in.

This is just a slight "twist" on the Ideological Turing Test. It's important to understand even positions you don't believe in, and devising strong arguments for a position is a good test of understanding.

Of course competitive/formal "debate" has other well-known problems; most notably, the artificial requirement to address every single element of the opposing argument in your response incents gish-gallop arguments.
