Computer PSUs are generally more efficient at european electical standards. I read many a thread two years ago about cryptominers in America wiring our heavy appliance 220v lines into their racks to approach the efficiency that PSUs can reach at higher volts.

And of course some datacenters just wire DC to the whole schebang instead of having an individual, well two redundant, PSUs per server.
It is an intentionally misleading term. The first sentence of the IMF study's abstract makes it clear the their 5.2T figure is the difference between market prices and imaginary prices that account for all externalities, including some quant's estimated cost of climate change.

This isn't even one of those situations where their use of the word is technically correct. I've never seen a definition of 'subsidy' that wasn't an out-of-pocket expense paid by governments.

The use of the word subsidy is intended to put the idea into our heads that we're all paying out of pocket via taxes to support the fossil fuels industries. But that is the opposite of the truth. With a few exceptions (the Petro-states) fossil fuel prices aren't artificially lowered by subsidies, but rather are bloated by taxes paid by corporations and by end consumers. Fossil fuel industries fund our governments, our roads and infrastructure.
Imagine a world where you could.

It's a tooling problem more than a budget one.

In fifty years I think we'll be telling the machines what stories we want to experience. But between now and that dreamy future, there are intermediate points along the path that empower individual or small groups of creatives to lift mountains - I think of it much in the same way as languages and tools and libraries make it so we don't have to string together vacuum tubes to solve our problems. Think about the kinds of problems filmmakers face: writing a cohesive narrative, finding and lighting a scene, editing massive amounts of video. It's all just a problem of tooling.

When there is a way that lets you or anyone with an ounce of creativity turn their dreams into polished, watchable content, it will democratize storytelling.
I've gone through the phase of distrusting individual papers and relying on reviews.

Only to again realize that reviews are also often vehicles of bias perpetuated by the authors where they subtly amp up papers by themselves and their "clique" of researchers.

Only solution really is to just read as much as possible, be as critical as possible and never trust authors to interpret their results with full honesty.
All things considered, I’d say neither the horse, the goat or the husky are good metaphors for getting shit done. The bull is ;)
They may already be doing this , at least for research purpose. Sounds like a good idea but difficult to scale.
One thing I really wish some of these editors had were an IDE-like sidebar.

Whenever I'm editing markdown files, it's usually in a folder of notes, or blog posts, or writing of some kind. And it'd be nice to be able to cycle through several open files like you would in VS Code.

I tried writing my own but -- I just didn't have time and got bored of it.

Have you heard of editors that are specific for markdown and have this feature?
One thing that immediately comes to mind is that AR doesn't have that in-VR movement problem, that's notoriously hard to solve.

And it doesn't require those weird-looking and weird-feeling controllers to interact with the world.

So... maybe VR is not yet there, because the hardware does not allow for the full immersion that we unconsciously expect/want from a virtual reality?

You can still modify the code for personal and business use, as long as you’re not making money off of it, you’re fine. This is far better than it being closed source.
I don't think I've had it happen in running software but back when I was learning I wasted many hours trying to find where my error was with super unhelpful c++ errors, usually to find the problem was the crappy books I was learning from. In running software I've come across extra semi-colons causing issues, like when c and bash are mixed up:

if (foo);
fooBar();

Fortunately I've only wasted a couple of hours on that one.

The power law you are describing happens in nature too. Size of trees in forest, mass of stars, ect. You can't go deep enough to dig up it's source, so you get carte blanch freedom to make the distribution arguments however you want. But until you dig up the cause for why the system produces a power law output for wealth distribution that has happened pretty much throughout history, under monarchies or capitalism or whatever, then you're just shuffling deck chairs on a titanic argument.
They really aren’t. We have no way to meaningfully increase the surface area of the earth, it’s fixed. Even if we were to drain the oceans entirely, you’re just kicking the can down the road (ignoring the fact we’d likely all die).

Increasing our effectiveness removing natural resources doesn’t increase the amount on earth, so again, fixed. We will eventually run out.

Desalination assumes that the ocean is clean water. Micro plastics would like to have a word with you.

Show HN: My HTML5 game to turn yourself into a mumble rapper
For the past year, I've been working on this website as a hobby.

It's a music maker game / ironic novelty website that lets you turn yourself into a mumble rapper.

It uses ToneJS, React, Serverless, and a bit of machine learning to generate the rap lyrics and artist names.

Please let me know if the site works for you. If you make a rap, please share it! I would love to see the creative raps you all can make.

Let me know if you notice bugs or if you have ideas for more features.

I've tested it on a couple old android phones in the latest version of firefox and chrome. If anyone has an iphone, please let me know if it can work on the site (in safari chrome or firefox). I don't have access to an iphone to test myself.

Thank you for checking it out!

Best, Chris

> I've read you're supposed to just power through and eventually you get used to it

Wheeeeere did you read that?! I've been in the VR industry for the last 6 years and everyone I know vehemently recommends against doing that.
Well, let's put it this way - I have less than 2 years of lack of W-2 income. But yeah, you are reiterating my point, that credit score isn't necessarily what everything is based on. And what I was also thinking, is that I would not charge into bankruptcy assuming I knew what the consequences are. Everybody says you can get credit right afterwards, but I think "yeah, and that means they think you're a good risk for some reason other than your personal habits of paying debts, which sounds ominous".
Which by itself wouldn't really be a problem if they had any real advantages over fission, or some overwhelming lifecycle/weight/etc type advantage. But right now they pretty much loose on every metric that isn't measured in "gee-wiz".

I as much as anyone would love a Mr Fusion from back to the future, even if it required hydrogen/etc rather than food waste, but the truth is none of the current designs have clear paths forward to grid scale production, or even small self contained units as used on subs or potentially space applications.

I do think we should be funding the research, but I also think we should be spending equal amounts on engineering better fission processes. The former is basic research while the latter is targeted engineering.
Well, the reality is oddly close to the fantasy, actually.
According to Wikipedia (Origin_of_water_on_Earth):

> The region of the protoplanetary disk closest to the Sun was very hot early in the history of the Solar System, and it is not feasible that oceans of water condensed with the Earth as it formed. Further from the young Sun where temperatures were cooler, water could condense and form icy planetesimals. The boundary of the region where ice could form in the early Solar System is known as the frost line (or snow line), and is located in the modern asteroid belt, between about 2.7 and 3.1 astronomical units (AU) from the Sun.[18][19] It is therefore necessary that objects forming beyond the frost line–such as comets, trans-Neptunian objects, and water-rich meteoroids (protoplanets)–delivered water to Earth.
I don't get this. If I can't rely on having a charger every day, I have to plan on being able to get home without one, and then why have it?
it reminds me Archer’s stakes.
https://en.m.wikipedia.org/wiki/Archer%27s_stake
I've never gone as far as what I would consider "writing software". Whenever I've seen something software would easily solve, it's been easy to hack together with some off-the-shelf tools. Several times I've set up Google Forms (or just had everyone edit a spreadsheet directly) to collect input and then sent the CSV to a little Python script that solved some problem.

Probably my favorite was when my parents decided to pre-bequeath a bunch of their books, movies, and other items they thought their children would like to keep and weren't worth selling. I had everyone enter their prioritized preferences on hundreds of items, and implemented a little algorithm to give people their first preference, with preference towards people that desired fewer things. Saved my parents a lot of overhead and everyone was happy with the result.

Amazon has made lots of products more discoverable. But that's only one component of "help me find what I'm looking for."

Case in point: I'm in the market for a new TV. Based on my experience with prior TVs, I believe I want something with high contrast, low reflections (glare), low response time, and high color gamut coverage. Well, some balance of those criteria weighed against price. I'm new to the TV market: how do I find this (on Amazon or elsewhere?)

If I expand, the situation might seem worse. I'm tangentially familiar with two modern display technologies: LCD and LED. I know LEDs offer higher contrast and quicker response time. So I search for LED TV on Amazon. Most of the results do indeed have "LED" and "TV" in the name, and nothing on the product page suggests anything different. But look up detailed specs for that model (which takes some determination in and of itself) and it has none of the characteristics of an LED TV. The contrast is low, the response time is high, in fact it turns out it's an LCD TV! Apparently the industry markets using LED to mean LED _backlight_, which to me was misleading. So what class of TV will get me what I'm after? There are places to figure it all out, but Amazon sure as hell isn't one of them. Nor is Best Buy, Walmart, or most other retailers you've heard of. They still do an awful job helping you find what you're looking for in many cases.
There is no potentially detectable 'implant' required in these cases, it can be sufficient to capture a factory initialized private key.

The width supply chain of computers is enormous, and only a tiny fraction of computers available are interesting to compromise. This would make it astronomically expensive to compromise a significant fraction of all computers that are useful to compromise and the risk of detection would be fairly high. The market of security keys is relatively small and a significant portion are worth compromising, compromises there are much more effective.

If state actors do not completely compromise the manufacture of these keys then they are extremely incompetent and derelict in their duties.

Put another way, if the {pick your boogeyman state} government started issuing hardware cryptokeys and suggesting you use them as a single factor access to your servers, what would you think of that?

Would your opinion be improved if they just didn't announce that they were the boogeyman state and instead did business under a cover company?

Do you have any realistic means of determining that this isn't happening?

"I let someone else generate my secret keys for me" is a failure at the most basic level of security, and that failure isn't removed by them also putting the secret keys in a potted, opaque, and unauditable hardware device.

Yubikey as a second factor is a fantastic improvement-- it's a quite strong protection against attackers who couldn't compromise the keys.

Yubikey as a single factor is simply key escrow with extra steps.

Claiming that trusting the devices own 'fingerprint permission' is two-factor is deceptive since an attacker which has compromised the device's construction, design, or confidentiality of its state only faces one-factor security.

It's exceptionally hard to start when the end results (i.e. other more experienced people) are so graceful or impressive. It makes the beginning seem like such a farce. Like going to the gym and deadlifting an empty bar beside someone pulling 5 or 6 hundred pounds off the floor.

But yeah, you have to start somewhere.

Simultaneous Localization and Mapping (SLAM)
I'm not so sure. Lack of outside visibility seems more like a feature to me than a problem with the medium; the whole point of VR is to remove you from the real world and place you in a virtual one.

As for motion sickness; with modern headsets that's generally only a problem for games which move the "camera" in ways which don't match your movement in the real world. (Such as racing games.) There's plenty of content available these days which doesn't have that problem.

Space restrictions I agree are an issue. There are a lot of games which only really need standing room to work well, but even then it can be hard to find enough space close to your PC (since the area you're standing in needs to be completely free of obstacles you could hit with your hands). I think standalone VR partially solves this problem though by increasing the number of areas you can set up in. With Quest, for example, the area you're playing in doesn't have to be near your PC; that makes it way easier to find a space that's big enough.
So you mean being okay with a multibillion dollar corporation harming people so it can make even more profits, all the while telling you that it's "good for society"

"Haha some company got breached and they made decisions I consider a mistake. Haha they hired a CISSP,how lame."

How marvelously retarded. How about demonstrating some understanding of the complexities and difficulties involved in securing any large corporation? How about suggesting some solutions?

I can tell you one problem clearly: Management and C-suite do not get clear,useful and actionable security risk analysis with what practical solutions exist. I can also tell you idiots who communicate this way are worse than actual hackers trying to breach companies.

Of course there is a bigger problem of legal accountability which is a law making and voter education problem.

Oh and regarding CISSPs, do you have any idea how hard it is to hire people that know their tradecraft? Even for a decent salary and benefits and schedule? Very difficult if you're not a fortune 100! Would OSCP impress you? Wth is a guy who only knows pentesting worth unless you're hiring for a pentester? Heck, a CISSP that can't even code but undetstands security threats/risk and can communicate is worth 20 OSCPs for most orgs!
Those are pretty large problems. As an outsider it seems that the people bullish on VR think consumers, with respect to these problems you mentioned, will just get over it because of how compelling VR is. It seems obvious to me that they will not get over it.

The lack of any outside visibility is a huge problem for families. It is anti-social. Small kids can't be near you while you are using VR. Pets can't really be near you.

It's very difficult to share your experience with other people. VR streamers aren't very popular on Twitch. They probably have issues interacting with their audience since they can't easily see Twitch chat I would think.

I also question the accessibility of VR. At what severity of physical impairment does VR become unusable?

There are just so many problems with VR as a mass-consumer product that don't have anything to do with technology.

AR doesn't have many of these problems, because you can still see other people.

Google's direction makes sense.
Don’t know if this is intentional but you have some seriously nasty 18+ advertisements on the bottom of that page. No way I am clicking on anything on your site.
Largely, it comes down to Android being a bad OS for input latency (indeed, Oculus and Samsung had to perform what John Carmack described as "deep hacks" into the Android kernel to get it to a reasonable state with Gear VR), most phones not having a high-enough quality IMU for tracking head motion, and most phones not having a low persistence display (high persistence causes a smearing effect in the visual).

So while "Cardboard" can "work" on most phones, it's a pretty terrible experience, once you get past the awe factor of seeing stereoscopic visuals with head tracking. Us developers have largely stopped making anything with basic "Cardboard" support, for fear of giving people a bad first impression of VR.

As for Daydream, a lot of the point of the Daydream system was to get around those issues I mentioned. First, it required phones to meet a certain hardware profile to before they were allowed to market themselves as "Daydream Compatible". Second, it included changes to the operating system to provide much lower latency in input tracking and change display settings to reduce pixel persistence.
