This is an awkward thing to demo because it has look good, but it also has to look "good". I didn't think the second video with the black woman and the asian man was very impressive. They look airbrushed, which makes sense because you don't want to say "hey, look at how believable these ugly craggy people are", but on the other hand I think it plays it too safe by not showing off what they can do.

Of course, that's not really the point. The point is that the metahuman creator tool apparently makes it very fast-and-easy-ish to create "metahuman" characters that look a notch or two better than the Final Fantasy movie from 20 years ago.

The older faces that they made in the video that demoed the tool itself, rather than the result, were pretty impressive.
Yep, it even has a GC for the C++ based entities.
Read and understand the thirteen books of the Elements by Euclid, preferably in the original Greek. This ought to be sufficient for a fundamental understanding of the mathematical method, its power and application--all generated from a handful of axioms and postulates which in turn can be re-visioned to form entirely distinct but consistent systems.

That would be great, but unfortunately the structure of problems that are well suited to proof of work (hard to compute but easy to verify in a decentralized way) doesn't seem to have too many practical applications.
Just curious, what do you feel is squeezing you to a more expensive product lately?

I still use a 2012 Mac mini from time to time. It recently stopped getting the latest OS upgrades, but getting 8ish years out of a product before being gently pushed to upgrade doesn't strike me as all that unreasonable or money-grabbing.
I think the issue is more that parts without correct encoded keys are not accepted by system, and in fact purposefully cause a “lock” of the system. Kind of like when your HP printer warns you that your printer cartridge isn’t name brand, but worse.

Also, the issue of voiding your warranty by using non-certified parts and repair centers.
Curious - I usually see you give reasons for doing stuff like this - I'm wondering why this was detached. Thanks!

Show HN: The Hitchhiker’s Guide to Online Anonymity (Updated to v0.7.2)
>> HN is designed to show you 30 "trending" stories at a time, and its refresh rate is pretty slow compared to social media like Facebook, Twitter or Reddit.

Yes - but tweets and Facebook posted each take seconds of your attention whereas a person can spend hours on a HN post, particularly when you leave multiple comments/replies and those receive replies.
You're probably right.

Thanks! Any framework can seem intimidating at first, but our dev team have put a lot of work into our docs in the past few weeks.

I had to look up GERD. This refers to the Grand Ethiopian Renaissance Dam, an under-construction hydropower dam on the Nile that is controversial due to its potential negative effects on Egypt's water access.
Correct. Ultimately, we will end up using Bitcoin as an asset and less for transactions. It is a better version of Gold.

> Blaming the tool for own failure to do the job isn't all that persuasive.

I would argue it is persuasive if switching to a new tool lead to success. What would be the point of continuing to try the thing that's not working?
And fnt has little to do with apt; it's a wrapper around curl + ar + tar, that doesn't support any of the important features of APT (signature checking, dependencies, updates, keeping track of what is installed, uninstalls, ...)
I'm not sure what's your point. Of course you can replicate every request in your scraper / with curl if you want to if you know all the input variables.

Doing that for web scraping purposes where everything is changing all the time and you have more than one target website is just not feasible if you have to reverse engineer some custom JS for every site. Using some kind of headless browser for modern websites will be way easier and more reliable.
Once you start accumulating all the fonts you needed over projects, your Inkscape and Gimp become terribly sluggish on booting. Other programs maybe too, I don't know, I don't use that many graphical tools or office programs.

And the font-selector dropdowns become unusable.

So I started manually moving stuff from /usr/share/fonts/ and ./.local/share/fonts/ into per-project archive folders. A lot of work, that a font-manager could easily do much better. Worse: manually moving stuff from /usr/share/fonts/ can and will bring them back "unexpected" on updates or reinstallation - though there are probably hardly ever updates for font packages.

I would love a tool like fnt to manage this for me, but it seems fnt is more for installing and less for "dis- and enabling" them per theme/project etc.

My favourite small detail on the Mac, is how the clipboard interacts with the filesystem. You can select some text, drag it into the Desktop and it will become a .Clipping. Now, if you drag and drop that clipping into a text field (e.g. textedit), it will be as if it was pasted.
Personally, I turned off the news in mid-October and that has improved my quality of life tremendously. I always told myself that since I was listening to NPR it wasn't the same garbage as cable news channels. Nope. Same click bait garbage. Particularly during the Trump era.

> Except it does [0].

That energy is used in production, not securing the existing stock of gold. With the very significant consequence for gold's "store of value" role that if environmental activists succeed in curtailing gold mining, gold owners would see their gold go up in value, not transactions becoming incredibly difficult and prone to fraud and a price crash. (But FWIW I'm not saying that gold mining to use as a "store of value" isn't also wasteful)

> It's worth something only if you can turn it into fuel, plastic or some other product for which there is demand. Same goes for gold.

I'm sorry to hear you find the aesthetic preferences of virtually every culture in history and the role they have played in promoting gold as a symbol of wealth laughable. You'd be surprised how much harder it is to enthuse them about the aesthetic properties of Bitcoins though.

And no, oil or gold is not "intrinsically worthless" because it is possible to use oil or gold for purposes other than exchange, and thus people value them for those use cases independently of beliefs about their future price.

> And although it's true that you can turn a piece of gold into a piece of jewelry that piece of jewelry will decrease in value over time unless it gains intangible value because of its history. Try buying a gold necklace and selling it the next day at the same value.

And yet gold necklaces of a given design are invariably more scarce in supply than Bitcoin! Almost like the demand side of the equation actually matters! Luckily, people do not buy gold necklaces solely because they believe gold necklaces will go up in price, and are not motivated to sell them as soon as they fear the price will fall in future. The same does not apply to Bitcoins, because unlike Bitcoins, people hold necklaces for the intrinsic pleasure of having a shiny necklace.

The unusual way I'm funding my open source work
The algorithm makes it such that the last coin will be mined sometime around 2140. My assumption is that people just plan on moving to another fork before that point.
Such a node becomes a payment processor, and must have a lot of BTC tied up in its channels in order to facilitate these payments.

It's basically a bank at that point. Or a worse Visa.
I'm so glad that Paul Hegarty is teaching this. Not only does he know the material through experience (I think he was an early employee at NeXT and continued on at Apple), he also explains things really well and works through lots of examples. It's also clear that he enjoys teaching the course, which makes a big difference.

I watched an earlier iteration of the course, and it's the reason I know iOS development today. I don't often write reviews (and certainly not on HN), but I absolutely have to recommended this course for anyone interested in learning mobile development.
I know for a fact that Alec either transcribes those videos himself (not hard to do from a script he already writes for himself), or gets it done by someone else before uploading the video.

I'm any case, they're always uploaded at the same time as the main video.

Also, YouTube recently removed the ability for individual users to contribute to captions of creators. There was a thread on HN about it.
That comparison is flawed. Visa is not money. The purpose of mining is to protect the value of the currency.

Protecting the value of the US dollar requires a huge economy with politics and military power.

The data is all readily available in the default Apple health app.

Yes, to make these same predictions you'd have to do some statistics as described in the paper, but no special app is required.

I'm not sure what's being said here is safe or appropriate. If you're doing nothing, your heart rate variance won't likely change. There's also very little that matters about it, just normals, for you.

Every Google Search I've ever done on HRV has turned up that fact: HRV is incredibly personal and personal trends matter the most.

From my own experience, my HRV is low when I'm not doing anything - and why wouldn't it be? I'm not _doing_ anything. I have no need for sudden changes when I'm typing on a keyboard.

Further, you can be as healthy as a marathon runner and have very low HRVs.
A lot of energy at plants is not transported to economic centers because it will be lost on the way.

In some places that energy is burned off into the atmosphere instead, in other places plants are just operating underneath the capacity they already built.

Putting that towards bitcoin mining is by far the biggest impact, as in it is either positive impact (reducing burning) or no impact, and the heat concern and the hardware creation concern are comparatively much smaller. Much of the potential e-waste actually winds up at these sites and continue to be used because the power cost is so low.

The heat is often transferred to something else that needs heat. Ive seen proposals for use in fish farms near the site, which were already generating their own heat with an inefficient means.

I’m telling you the answer. Not arguing for anything at all. The answer is acknowledging that fracking wont stop here are ways to reduce its impact. The answer is that hardware production wont stop, here are how it is being used as a sustainability solution greater than its heat and future e-waste reality. You aren't going to get your reality, and the existing reality is providing an economic practicality that nobody like you has ever come up with, its simple as that.
The late author JG Ballard once suggested that the monarchy should be abolished, but that the British government should work with Disney to have lifelike robotic replicas made. Cheaper in the long run, and Disney World is quite popular after all.
That's efficient if you define efficiency as hashes computed per watt. That's the metric by which less-efficient miners are driven out.

However, this does nothing for the overall energy efficiency of Bitcoin, which could be defined as transactions processed per gigawatt. If energy gets cheaper, that number only gets smaller.
> No it just always always goes up regardless of transaction volume as the block-difficulty increases infinitely.

[sigh] The difficulty adjustment is so a block is issued on average every 10 minutes. It therefore does not increase infinitely but both increases and decreases depending on the amount of hashpower in the network.

Pretty much every bank in the US is obsessed with having identical security practices so they can feel like they can say they are industry standard if they are hacked.

There are banks with hardware 2FA in European branches that still restrict to SMS only in the US.

US banking security is a joke. IMO move your number to a VOIP provider with hardware 2FA support and transfer lock it to limit the worst of SIM Swap risk.
It is a tricky problem - on one hand, we want to capture as much as you can with DSL, since that gives us power to "do more", but on the other hand, we want to give you all the flexibility you need, which means doing stuff outside of DSL, stuff that Wasp does not understand and only sees as a black box. We think we can solve this by offering multiple levels of abstraction to choose from + escape mechanisms on the right places, and we are integrating with the JS ecosystem so you can write a lot of the natively already (NodeJS, React, more in the future).

So while we still don't have this completely figured out (and I don't think we will until we get it done), we are hopeful! One cool thing is that doing our DSL also gives us a lot of freedom here, to find the best abstraction.

Awesome, ping us on our Discord (https://discord.com/invite/rzdnErX) if you will have any questions - Wasp is still in early alpha and rough around the edges (including missing flexibility), so if you get stuck anywhere let us know! Actually ping us anyway if you wish, we would love to hear how you found the experience, how hard was it to get into it.
Can’t Find an N95 Mask? This Company Has 30M That It Can’t Sell
I track mine on my Apple Watch which records it in the Health App. It's basic graph and I can download it if I want, but I've found tracking day-over-day/week-over-week is a good enough signal. For example, I did dry January this year and practiced meditation every day since and I've seen a step-jump up corresponding to that.

Still have to keep another record of external factors to correlate with it, though. I've heard people finding success with a 3p monitor and the Elite HRV app as well [0].

> Curious what HNers think about this - is it bad to have Bitcoin in light of how bad the environmental impact is

Having them actually has no or negligible impact. Unfortunately getting rid of them is a transaction which will incur an unreasonable cost to the environment. The best thing might be to destroy them (the media they're stored on). And no, nobody expects you to do so.

I'd would sell them before they get banned, as they must.
Monte Carlo Simulation – Everything You Need to Know
There are better presentations of geometry than the Elements :) (Plus, the original constructions, without algebra, are rather tricky and don't generalize well!)

If we're interested in the mathematical method and its power, a good start might be to, well, go with more exploration-based approaches, where students have to learn things in order to solve a "real"(-ish) problem. Of course, the training required and attention to students would rocket and is likely infeasible, but hey, if Euclid's elements in the original Greek are on the table, this doesn't look too bad !
>I am not saying that it can't be mismanaged by a state, but you do not have anything better than state fiat money.

I agree with this! At the moment I don't see many things that are better yet. I hope to see an obvious winner someday.

EDIT: For the record, I hold no Bitcoin. While it has a lot of potential value in creating Freedom To Transact, I'm not convinced the current price per unit is anything but a Pump and Dump. If Bitcoin is a Constitution of Money, it's a pretty fucked up one.
Also imho the latest M1 air is excellent value for money. Cheap, great screen. And macOS.
tzset manpage for glibc explains this:

If the file specification filespec is omitted, or its value cannot be interpreted, then Coordi‐
nated Universal Time (UTC) is used. If filespec is given, it specifies another tzfile(5)-format
file to read the timezone information from. If filespec does not begin with a '/', the file
specification is relative to the system timezone directory. If the colon is omitted each of the
above TZ formats will be tried.
I also find it funny. But the key redeeming feature is that it was paused, and automatically sent to human review. So sure, your cert takes a little while to issue but no significant harm.

The obvious contrast is Google closing legitimate paying accounts with no option for human review.
I'm a little torn on this one. On the one hand I see it, because it feels like patterns books made the limitations of C++/Java/C# seem respectable, even desirable. Norvig observed this with his talk on patterns in dynamic languages (p. 10 of https://norvig.com/design-patterns/ summarizes this).

On the other hand, I have found his work to be useful in selling approaches to others. There were times where I did a design, then browsed the patterns books to find names for what I was doing to "make it respectable."
Back in the 80s, we learned the Euclid axioms and postulates in geometry class which was around 8th grade. Not sure what is taught these days.

Edit: I think that was the first class where we learned about proofs and we solved so many that I really get the hang of it.
> If there is more consumption of electricity, that raises the price, it doesn't make it cheaper. Of course the bitcoin miners would like to buy it cheaper. The power companies would like to make it more expensive. Economics dictates that their meeting point will be higher with more demand.

First of all, economics dictates that supply will catch up to meet the demand as long as the barrier to entry is low. You'd be right if there was a cartel in green energy — but there's not. As long as supply is elastic, high prices are always transient.

> You're describing it as if BitCoin miners have the ability to construct their own gigawatt power plant.

No, I'm describing it as if BitCoin miners have the ability to set up ASICs powered by solar panels in the middle of a desert in Nevada. Somewhat high upfront cost, but effectively zero marginal cost of power. What's being stimulated here is the demand for accessible solar panels that can be quickly/cheaply installed.

> If I burn 100 TWh/yr of electricity, and they build a power plant for me that supplies 100 TWh/yr of green power, how, exactly, have I reduced the demand for fossil fuels? I'm burning all the new green energy that's being created!

But again, that presupposes that there's some fixed supply. Supply also changes, and it responds to demand. This is the core thesis behind Keynesian stimulus, and why inflation doesn't necessarily follow from stimulating demand.

Now, baked into all of my points here is the assumption that the barrier to entry for new supply is low. It might not be! That's, I think, the more interesting question. The market conditions could also change making it easier and easier to spin up a solar farm, or spin up a wind-farm.

On my other comment, I forgot to note that I phased in the three lifestyle changes. First I started the supplements and that provided most of the drop (down to 130/80 ish). Then I layered on the exercise, reduced caffeine, and change in diet. So most of the drop first came from supplements.
Hunting elephants is legal and can help protection for the species. The real problem is in the context.

EU project is only partially compatible with monarchy, you either have the power or don't and monarchs can only slowly lose more and more power to bankers with time. Thus, the current anti monarchy trend in many countries of Europe would be expectable. British probably see it coming and jumped of the train.
Upvoting you because the downvoting was unfair.

Nevertheless I think your position is naive; most interesting and engaging apps need more information than you can get from a generic tool alone.
> I just stumbled upon an example some days ago, when I needed to add a screenshot image to a PDF. It was surprisingly easy in the Mac: Double click the PDF to open it in preview, double click the image to open it in preview and then drag the file icon of the image into the pages view of the PDF. And the image is inserted as a page in the PDF without any issues.

That is a great use case!

And screenshots on mac are, IMHO, hard to use.

The screenshot UI is frustrating, where to save to is under options, you cannot preview your screenshot, you cannot annotate the screenshot (something I do all the time on Windows), and having to choose between saving to file or clipboard is annoying.

I wanted to record video, which the Screenshot app can do! I know that because I googled for it, saw it could do it, and then spent a good 4-5 minutes trying to figure out HOW to do it before I realized the tiny grey scale circle overlaid on a couple of the toolbar icons meant "record".

(Red circles mean record, grey circles don't have much meaning, but hey, need to keep that UI minimal, can't let usability or actual meaning get in the way!)

The Windows Snipping Tool (RIP) is IMHO the best paradigm for doing screenshots.
