Really only winning matters at your current rank, other metrics can be deceiving.

For instance according to the tool my league account is D-tier in most metrics and gets an overall ~400/1000, except that it has a near 60% winrate over 200 games on my main role while playing against the top-5% of players in my region. As a toplaner I generally want to be on the opposite side of the map from the current objective and I'm not going to get to participate in many kills either - so my objective participation and kill participation are both D-tier. If I made improving those metrics my goal I'd be playing incorrectly and I'd likely lose more games.

In a shooter a high KDA in [current rank] is going to correlate better with winrate, since killing your opponent is the main avenue to victory, however you could still imagine a hypothetical player who gets a lot of kills but makes the game so hard for the rest of their team, they lose anyways.

At the end of the day, only your current winrate is a reliable metric for how fast you're going to climb from your current rank.
A billion is 10^9, billions around 10^10, thus one or two orders of magnitude more suitcases.

I didn't say they were free, I said that the energy doesn't show up on anyone's (energy) books. You know which books I mean: they're the ones where companies & countries report their energy reserves, the amount mined/burned/imported/exported, new discoveries this year, etc etc.

The reason this matters is because there's a lazy temptation to run the Electrification Calculation merely by looking up the amount of primary fossil energy burned annually, then assuming 100% of this must be replaced by solar/wind/whatever. However this simplistic calculation will over-estimate the amount of renewable energy needed by a factor of roughly 3x.

>This site doesn't even mention solar or the efficiency thereof.

I fear you only want to 'win the debate' (vs reading for comprehension), but...

The entire thesis of the article is how mass renewable electrification enjoys large system efficiency gains over fossil fuels. It's pretty evident how solar is a critical enabler of mass renewable electrification.
The searchable keyword to look for here (re x86) is "Total Store Ordering" (TSO).

(I'm not gonna try to summarize it here because I'd probably get it ever so subtly wrong…)

x86 has a very strong memory model, meaning it is a very poor test platform. Last time I touched atomics I used PowerPC (e500mc & e6500) to test, which was a good thing as it did point me at a problem. Not sure where current ARM falls on this. The uncontested, notorious king of weak memory ordering is DEC Alpha, but these are a bit hard to run these days. If you want to go truly insane, look at DEC Alpha consumer dependency (non-)ordering :)
...so it wasn't ancient aliens, with laser-cutting and other amazing technology? That's disappointing. I mean, if I couldn't imagine how it possibly could've been done, then it had to be the aliens, right?
I didn't know that metaphysics, consciousness, and the physical complexities of my neurology are considered solved problems, though I suppose anything is as long as you handwave the unsolved parts as "functionally meaningless".

Another reason this unfortunately wouldn't be viable is latency - a video feed has no client side prediction.
In addition to being a bit of a digital hoarder, I have a decent collection of enlarged anime background paintings on the walls at my office. My tastes in subject matter are pretty wide ranging, but I don’t have a specific collection of the 80s anime film megacities paintings. This book seems to fill a gap I didn’t even think I had in what I display.

I was super impressed by the price point of this book. All the reviews say the print quality is excellent. $45 for a ~250 page hardcover is a great deal even if you just want it to sit on a coffee table or book shelf. Thanks for the tip, I ordered immediately, and it’s going on the small desk in my office.
I love that analogy with birds!

Yes we figured out how to build aircraft.

But it can not be compared to a bird flying. Neither in terms of efficiency or elegance.
I don't know about that, I think cave painting was highly meme driven.

Chauvet Cave and Lascaux are similar (lots of overlapping paintings of large animals), but some 16,000 years separate them. Is that individual self-expression? It looks to me like entrenched tradition.

Stencil paintings of hands are a common theme, but bizarrely are found all over the world: Argentina, France, North Africa, Australia. This too can only be a meme, I think. Possibly the method, spitting out paint, was the meme, and the idea of making stencils of hands arose naturally by accident in all these places, but even then there is no sign of real individual self-expression going on. It's also intriguing to me that three of the places I mentioned (on three different continents!) include stencils of animal hands (large birds or lizards).
The point, which I should have stated explicitly, is that the solar panels that break should/can be recycled. And so recycling is also needed for this percentage.
Not necessarily. You could load up one black hole with electrons and the other black hole with anti-protons ... both would have negative charge, -Q ... but the latter would have a much greater mass, since anti-protons are much heavier than electrons, despite having equal charges.

"Antimatter" is really only "anti" in a few respects. First, the lepton or baryon number has the sign flipped. An electron has a positive lepton number; a positron would have a negative lepton number. The charges are also flipped, where applicable (anti-neutrons still have a charge of zero). Isospin is flipped; spin is not. Mass is not, in three ways.

First, if you converted an anti-proton into pure energy (ignoring charge conservation, et al), it is the same energy as you would get out of a proton.

Second, an anti-proton exerts the same gravitational pull as a proton. A world of anti-matter would cause you to fall toward it the same way the Earth would.

Third, a force exerted on an antiproton causes it to accelerate along the same vector as the force, so the inertia is the same as regular matter.

People have theorized, myself included, on what some kind of matter where mass was negative (let's dub it nega-matter) would look like, which is to say that a force pushing it away would contrarily draw it toward you. You can simulate it in particle life, likely, but what would happens is that all of the nega-electrons would feel electrostatic repulsion and therefore clump together, as would all of the nega-protons. These two lumps of enormous charge (we just don't get that in real life, electrostatics are dozens of orders of magnitude more powerful than gravity) would create an "attractive" field between them of nearly incalculable strength and, because they would move opposite to the vector of the force, promptly zoom away at many nines of the speed of light. In short, they would sort themselves out and fly away to distant corners of the universe with great haste.

Not only that, consider the societal advantage of this behavior. Many social rules are wrong and group-level maladaptive. Having a subset of the population that doesn't adhere to those rules benefits society by allowing it to break out of local maxima.

It's not a tendency we should suppress. Punishing people for non-conformity is the act of a villain. And yet we do, so that only people with wealth can survive doing it.
Show HN: Open-Source Video Editor Web App
Hey everyone, for the past like six months I've been working on a portfolio project. I got tired of doing easy projects, so I decided to tackle something bigger and more challenging. That's when I came up with the idea of a video editor. This piece of work is intended to showcase my skills and land me a job, but I like to think when working on projects that my idea is so cool that people will like to use it, and I treat every project like a startup idea. Also I havent seen many open source video editors especially on web so that was one of the points why I decided to make that and not something else, but in the end its learning experience and im not expecting much if at all.

A bit about the video editor itself:

-website: https://omniclip.app/

-its free

-its open source (MIT Licensed)

-its using Webcodecs API for quick rendering

-works fully inside browser, client side, no private data is kept

-I made some readme with more details, im not expecting contributions but I added bit about it: https://github.com/aegir-assembly/omni-clip

Features:

-Trimming

-Splitting

-Supports - Text, Audio, Video (mp4) and Images

-Clip editing on preview - rotating, resizing, text styling and more

-Undo/Redo

-Render in different resolutions, up to 4k.

Things to know before using this editor:

-it is simple editor, but its my main project im working on and improving it.

-right now it only works with videos 25 fps and more but not less

-only 4 tracks -- its something I could improve quickly but forgot

-bug here and there (eg. filmstrip not rendering until timeline scroll moved)

-its not working on phones yet (drag and drop API problems)

I'd love to hear your thoughts and feedback on it.
I remember being blown away by Debian. It packed most common network card drivers, so that you needed just two diskettes to bootstrap the installation, and the rest was downloaded.

Of course, QNX was even more impressive, packing the os, windowing system, network and modem drivers, and a web browser on one single diskette. Amazing.
In the early 00’s, I used this technique to write a keyboard driver for a handheld computer, using a PIC microcontroller. The method was shown to me by a senior EE who previously worked on HP calculators, after HP had outsourced that division to another country. I learned a lot of tricks like that while at that job, as I was the only one on the team who was not a former senior HP engineer. They knew their stuff, and their stories about the outsourcing made me forever reluctant to buy anything made by HP.

The "problem" with doomers is that they offer no nuance. Almost all of the issues people talk about are real issues we should be taking action on. But when assertions like "climate change is going to kill us all" are thrown around, it leaves very little room for actual change, and effectively demoralizes other people.

despite the separation of duties, at first glance, it would appear worthwhile to me for the customs agencies to buy access to the CT scanners or just the output from the security agencies so they could easily detect the cash

maybe there are laws regarding privacy or just bureaucratic challenges that prevent this though
I've used languages with and without garbage collection. Usually, manual is more difficult to write, automatic is more difficult to troubleshoot.

I would love to use a language that allows me to do both. Writing exploratory code is more convenient using automatic memory management. There are certain kinds of code that benefit from manual memory management.

I find appalling that people can't find a middle ground between forbidden and mandatory.
My gut reaction to this sort of thing is that textbooks work great and have a timeless quality. But with a little more thought, they certainly aren't optimal. Being able to see a video, hear a sound, or play with a figure can be powerful learning. I think my hesitation comes from the fact that this stuff just doesn't seem to have longevity (think educational java applets) and tends to be proprietary (shitty Pearson learning hw). How can we get newer media as robust as text and pngs?

Yes, that makes a big difference.

Many people on HN formed their opinions on the basis of GPT3.x-generation models, though. They asked it a question, they got the nonsensical or hallucinated answer they expected, they drew the conclusion they wanted to draw all along, and by golly, that settles it, once and for all.
Yes, but there any old schmuck can put some dollars in and get the same return.

Good luck trying that with one of those very profitable market makers and funds: they don't want your capital; or at least they don't want it at the same price (= returns) that we are quoting here. Which suggests that those returns aren't attributable to that capital at all (even though for tax reasons they might structured it so that legally these are counted as capital returns, but that just obscures the underlying economic reality).

This is very similar to observing that a particular company pays a lot of money for some very simple job; but then we notice that the job is only available for the son of the CEO. We can conclude that the extra pay isn't really for that simple job.

Or when we notice that a government contractor officially charges 5000 dollars for a hammer. Unless you and me could rock up and steal market share by offering to sell hammers for 4000 dollars, it's very likely that the 5000 dollars aren't really for the hammer at all; but just some accounting shenanigans.

I'm also surprised by that claim. Every time I've flown with a thick book in my carryon, it's been flagged for inspection. One of the staff told me once that it's because thick stacks of paper look a lot like plastic explosive on an X-ray. I have to imagine a suitcase full of cash would look the same way.

I want to disagree with him and I want to agree with him in almost equal measure, I think that is ambivalence. My cynicism says that people like him, people who create psychologically dense pieces for the BBC, are actually on the side of conformity. I've felt since I was young that we are being sold our revolutions. They've firmly commoditized the opposition.

I'm tired of the politicization of everything. Even in this piece, there is an implicit call to political action underneath his attempted reframing of individualism. He wants us to see the power in being a member of a group. It is some kind of call to group-think, to pretend you are an individual and yet still act within a political body seeking power.

The real question I have is much deeper. Sapolsky has been on the podcast circuit pushing his new book that insists we have no free will whatsoever. Žižek claims that we are locked inside our ideologies. But I keep going back to ancient Greek philosophical ideas that entreat me to "know thyself".

I heard on a podcast recently that Sartre's lament that "hell is other people" is best interpreted as the observation that our instinct to mimic others invades our own freedom. When our peer group expresses strong virtues we are pressured to conform by threat of ostracization. This leads to anxiety as our own sense of virtue may be misaligned according to the group.

Yet I have a growing belief that finding my own virtue, something that completely originates within myself independent of external influence, is the real key. And Curtis here is suggesting that technology can be used to that purpose, to unite like-minded individuals based on their genuine virtues.

I suppose it is the power-seeking aspect of this piece that sits poorly with me. That I would (or should) seek other like-minded people for the purpose of exerting some political influence. It seems to me that just identifying and remaining true to virtues that I feel originate within myself is hard enough. To also consider the political consequences of grouping up with others and combining our resources to affect societal change is more than I want.

It reminds me of the conversation Jesus is said to have had with Pontius Pilate. He asks Jesus if he is trying to raise an army to overthrow the Roman order and Jesus responds that the Kingdom he is interested isn't of this Earth. There is something to that religious language which I think we've forgotten.

TSA agents are federal employees and federal law prohibits carrying-on ammunition on planes. It is not Boston specific other than that's where OP got caught. You can still check it if you want. I assume the reason is to reduce the chances of accidental discharge causing risk to the plane and/or the prevent one part of a weapon that could be used for hijacking. Even if laws allowed you to take bullets into airports, I have no doubt that the airlines (private business people choose to patronize) would prohibit you from carrying ammunition onto their planes and they'd have every right to do so.
This report would be better received if it wasn't from 4 years ago and posted on a domain named flatkill.org--seems 'politicized'.

Any shortcomings of sandboxing has to be compared with something else to be practically meaningful. A sandbox that works when an application is appropriately packaged is better than not running in one for all applications.
Your argument only works for catastrophic insurance.

In practice, people take out insurance even for events that would not put them out of business.

Btw, if you are talking about 'value-generating enterprises', ie businesses as buyers of insurance, then your argument doesn't really work either, or at least not without caveats:

When a business suddenly has a large liability, and it goes bankrupt, all that happens is that the equity owners are wiped out and the creditors take over. The underlying business can and often does continue uninterrupted, and has approximately the same value as a going concern as before.

Also, being able to run as a going concern is of finite value to a business. If your business can take a 51% chance of either doubling in value or alternatively going bust, then that _might_ be a good gamble to take if your shareholders are well-diversified. For example, if index funds are your main shareholders.

Humans need considerable better odds before they consider such a gamble. But people do regularly put their life on the line in return for very finite benefits. Eg every time you leave the house, and drive a car. Or even more stark, any time people conveniently 'forget' to put their seatbelts on.
I believe you are mistaken, as so very many people are, about that document. If you are quoting an important legal document, it's important, wouldn't you agree, to get the exact text correct, otherwise the meaning might change? Especially if the text is used for justification to allow a wide, practically unregulated population to be armed? Let's see, I am willing to bet the following statement is the actual quote from the document you reference, which says something quite different (to me). Here it is: "A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed." nevermind that the more legal gun holders there are, the more opportunities for criminals to get guns. Legal gun owners routinely do not secure their weapons in the manner prescribed for responsible gun ownership(I grew up in the south, I can count the number of gun safes I've seen in houses on 1 hand). In fact, many decry the safeguards as imperiling their lives should a crisis spontaneously occur. I argue that those individuals are in fact responsible for a non-negligible amount of crime, since their actions (purchasing a firearm and then failing to secure it against threats) directly leads to more gun crime. But undoubtedly these reasonable arguments and facts will do nothing to move your position, so I guess I just wasted both our times.

I agree.

Btw, shared memory by itself is fine, even shared memory with threading. The really dangerous ingredient is mutability. And mutability is already toxic waste on its own, and concurrency amplifies the danger.
I can highly recommend Herb's talk as well!
Here's my take. Asserts are a kind of error handling. They handle situations where the code can tell that it's off the rails. It might be off the rails due to a hardware error or a software implementation error, e.g., a 'can't happen' situation.

We didn't have debug-only asserts. Asserts were enable in the software we verified and shipped.

It took a while for developers to be able to determine when a situation called for an assert, and when it called for what might be called traditional error handling.

The strategy of shipping with asserts enabled kind of worried some folks. They were concerned that it might assert in front of a customer. I understand the concern, but in our domain, if you're doing an OB exam with the ultrasound system and you have a choice of asserting or showing a femur length measurement of -1039cm, which is better?

We didn't have many asserts in the field. We had a lab where we had about 25 - 30 ultrasound machines running embedded tests constantly. Each machine was connected to a JTAG debug board, so we could flash new code into the system and so we could set a breakpoint on the assert routine itself and save a "core dump" for subsequent debugging without having to try to reproduce the system state that led to the assert.

The whole lash-up evolved over a period of years. It worked well, so far as I know.

One mitigating factor was that our systems were class B devices. They were always supposed to be used by a medically trained professional that had the ability to take over if the system asserted, or power failed, etc.

Happy to try to answer any questions about this.

When you are close to the norm, it’s much easier to ignore your differences. When you are farther away, you have to decide what to do: deny them, accept them, mask them, amplify them.

None of us are truly normal.
Some confusion here: is self-expression about expressing personal moral ideas, perhaps political ideas? Because "art for art's sake" was originally (with the aesthetic movement of the 1870s) in opposition to didactic purposes for art. It was supposed to be about beauty rather than telling the audience something (which in mainstream art at the time typically meant something hamfistedly "improving").
