Definitely sounds like an inability to pitch correctly. In the case of a gambling game there are a number of things that you could pitch in a better way:

* It's possible to gamble even in jurisdictions that make it illegal.
* The rules are encoded and visible, the house might always win, but at least they're not cheating.

This does not surprise me one bit. I have a child and every time he gets sick his heart rate rises. The last time I noticed the heart rate first and called his mom telling her I think he is getting sick. The next day he had a fever.
Many of the same people who buy the Bitcoin-as-global-reserve-currency scenario also believe the Euro is going to collapse. It has known problems as a monetary union without a fiscal union, which lead to periodic bailout crises.

Here "deutsche mark" (and lira, which is another dead currency) are stand-ins for whatever national currency emerges after a Euro collapse. It may not be called that, but the point is that there will be some German national currency that settles up into Bitcoin in the international markets.

My sense is that theming like this is generally not aimed at people who would use a Mac in the first place, but rather BSD users who want something that looks more pleasant than their default window manager.

Creating a coherent visual language from scratch is a huge undertaking, and requires a certain skill set. Mimicking an existing design system is much more straightforward, even if the results are uneven.
It may be appealing enough for a user to try it, but I foresee disappointment. Mac OS is not only about the UI but also about all the software for it. How easy it is to install and use it out of the box. Drivers are never an issue. It is very unlikely that the average user will have to run commands in bash or edit some config files in a text editor.

It would be cool if some Linux variant could resemble Mac in this way.

For what it's worth, I think there is a lot of space between what you use and what might work for other people. It's not that there is anything wrong with Arch. Rather Ubuntu is probably easier for many people. The general idea here is Linux.

Similarly, there are several tiling window managers. A neutral description of the options and links to resources might have broader appeal. Text editors are another place where the right tool varies among people.

I guess what I am getting at is "highly opinionated" is better suited for ongoing processes than it is for soft goals. Arch Linux is highly opinionated. This makes reasoning about the ongoing process of maintaining a Linux installation consistent. The strong opinions of Arch Linux are orthogonal to the goal of switching to a tiling window manager. Ubuntu has a different way of reasoning about system maintenance that might offer less friction for other people. Tiling window managers are not dependent on distribution.

I'm not trying to change your opinion. Rather, I think that there are ways to make the book a more useful resource for more people by broadening it to "here's how I do it and here are some other ways that might work better for you."

Good luck.

Part of the argument can be easily circumvented. Have a look at gem install --user and bundle config set --global path. These allow you to install and manage all your gems in your homedir without the need for sudo. I do this all the time in Linux and OpenBSD to use the system ruby.
Ask HN: Inspired web designs that aren't overdone, but also not overly-brutalist
Every website these days either:

1. looks the exact same; I assume because they all hire the same designers who read the same design-blogs and uses the exact same libraries (bright colors, rounded corners and amorphous blob people [1] anyone?)

2. Belongs to a creative agency that hacks together some comical monstrosity held together by duct-tape [2] because its a show-piece but is not extendable, flexible or particularly robust (i.e. most of the attributes we'd associate with "quality engineering")

At the same time, I feel like HN's ideal of a website [3] (based on prior ask HN threads) is something comically brutalist thats more snobbish affectation than actually trying to appeal to society at large.

Given these two boundaries, has anybody ever encountered any inspired design for websites that's just... well made?

I absolutely LOVE that apple is slowly turning the screws on advertisers with these pro-privacy moves. It's been slow and incremental, but also increasingly hostile towards people and services that attempt to identify and market to end-users.

So new taxes to support the infrastructure that allows feeless ACH/payments? Not saying I'm for or against, I'm just trying to understand your argument in full. It seems like the logical way that your idea would be funded.
The economy does not account for the environment, that is what is wrong with the current economic system. Bitcoin did not fix that, but it fixes that there is no central bank other than miners.
The point is that Bitcoin isn't inherently carbon positive. It's carbon positivity depends on the power source used to mine it and carbon neutral power becomes cheaper and more available every day.
I strongly dislike Apple's business practices, the vendor lock-in they continue to create and the way they design their software and hardware, but this is undoubtedly a move in the right direction.

As a user, I want to have the option to globally disable all tracking. Random advertiser IDs every time one is requested, no sharing of vendor IDs, just quit it. Gather your statistics from people who don't care about privacy or people too tech-illiterate to disable the checkbox, but don't force your terrible tracking down the customer's throat. Or rather, disable the tracking by default, make it opt-in per app. If your app is crap but useful enough, people will want to improve it.

Now, if Apple did that, all the Silicon Valley startups around app optimisation would cry foul, Facebook and Google would sue Apple and there'd be a massive PR campaign against Apple, so they can't do ever what I'd like them to do.

Lots of developers seem to act as if they have a god-given right to track people to gather analytics rather than doing some costly end-user research. These were probably the same developers who proclaimed that the GDPR would end all computing as we know it because now they have the legal obligation to care about their customers' privacy.

You need height to get ‘serious’ hydro power. In the Netherlands, the Rhine water drops by less than 20 meters across the entire country (ballpark 100km), so I think a 1 m drop already would be optimistic.

So let’s take that 7000m³ and drop it by a meter. That’s dropping 7 million kg of water by one meter, or (if my math is right) about 70 MW of potential energy. You might get somewhat more out by decreasing the speed at which the water flows, but I doubt that would be much (the more you slow the water down, the larger the river downstream has to be)

Also, that’s if you dam the entire river. The Waal is a major river for shipping, so you can’t do that.

Finally, I think 7000m³/s is an outlier. Google gives me 1500m³/s flow rate for the Waal (and, consistent with that, 2000m³/s for the Rhine). So, on average, a system damming of the whole river, requiring all ships to go through locks, would produce about 15MW.

And I think my math is at least in the right ballpark. https://en.wikipedia.org/wiki/Beauharnois_generating_station generates “up to 1,903 MW of electrical power”, but it has a water drop of 24 meters, and runs in a river that has an average discharge about equal to that peak of that of the Waal (https://en.wikipedia.org/wiki/Saint_Lawrence_River: “The average discharge at the river's source, the outflow of Lake Ontario, is 7,410 m³/s”), and, I would guess, is designed for somewhere around that average discharge, dropping surplus water over an overflow system. So, that would account for a factor of 24 (times the height) × 5 (flow rate)
Recaptcha comes to mind.

That said, there are quite a few services which battle these systems for you nowadays (such as scraperapi - not affiliated, not a user). They are not always successful, but they have an advantage of maaany residential proxies (no doubt totally ethically obtained /s, but that's another story).

Paw had that feel like it was made by Panic. It was a Mac app that was built with love, funded by a handful of dedicated users who love the app too and want to support the developer. The developer was building it out of passion. They know they aren't going to be on everyone's computers, but the computers they were installed on will have users that love the app above all else. Passion over download numbers.

Now it feels like Paw is going to go the route where they get as many users as possible, across as many Operating Systems. Individual user care is sacrificed in favor of mass adoption. Let's build a web version, lets build a version that your Grandma can use, why not a Kindle version while we are at it? Forget new features, let's build a better marketing site and start making commercials. I hear the superbowl is starting to sell commercials for next year, let's get in on that.
Bitcoin is so fundamentally deficient that I am absolutely shocked by its continuing popularity. I’ve tried and tried to think of a legitimate purpose for it, but I’m confident that it doesn’t have one.

It is just too slow and inefficient to be used as a currency, and I can’t understand why anybody would use something so volatile as a value storage mechanism similar to gold.

Transactions provide extremely dubious privacy as well, and governments still control it to a large extent via the exchanges, since at the end of the day, you still need to convert it to cash for anything useful.

Its only true use is for wild speculation and greed. It just makes me sick to think of the energy wasted by this when we are on the brink of climate catastrophe.

The golang stdlib is a little too barebones to be a better python, as well as not ergonomic enough. Faster, yes.
Yes, the finding is definitely interesting because it suggests that we could make this available very broadly (i.e., anyone with an appropriate Apple Watch) without needing to ship a bunch of hardware.

But the limitations are worth noting: you may already have infected people by the time this detects your illness. That isn't true for lateral flow tests, making the latter more useful as a preventative testing tool (again, in the absence of access differences).

However, I don't understand what you're trying to say with this claim:

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

"Do some statistics" is approximately as impossible as "order lateral flow test reagents" to the general public -- a consumable version of either the process described in this paper, or the lateral flow kits mentioned earlier, needs to be produced by someone skilled here, in order for this to be useful to the general public.
I like Ethereum not just because of the more responsible PoS but also because mining is currently asic resistant. A lot of the waste going into bitcoin right now is building specialized miners that will go into a landfill after a generation or two. Eth can still be mined with hardware you already own.
But it is true, about 75% of all electricity used in bitcoin mining is sourced from renewables. And the vast majority of bitcoin mining is large professional farms, not people using free electricity in their dorms. Bitcoin has been dominated by professionals since 2014.

I've used Taste a handful of times over the past year in NYC. Sometimes the dishes do not translate well to the at home experience (mostly crunchy things getting soggy). Sometimes it wasn't clear what dish was what or how things should be enjoyed. It feels a bit wasteful when you get the big bag of disposable containers. Overall though, it's a nice service for these pandemic times but I definitely prefer the in restaurant experience.

Strictly speaking rustc has a dependency on LLVM, which is in C++, but you could use the rustc_codegen_cranelift backend [1] and get pretty much everything to be pure Rust. Unless you count the libc dependency, in which case, um, I guess you could use relibc [2]? And if you think relying on OS syscalls implemented in not-Rust is cheating, then you could just use Redox directly ;)

If the rest of law enforcement is any indication then this should work out quite well and align the enforcers with what people actually want.

Look at poor city police departments. This is basically what they do. They prioritize the crimes that get their bosses yelled at by the politicians. It certainly isn't great for the officers who have to work in it but it's a great way to ensure resource allocation at least kinda sorta reflects the will of the people.

The FBI and EPA have no shortage of "you spent your resources doing what?" themed missteps. There needs to be some way to get them to do what people actually want them to do.
Wrist devices are generally not very accurate. I mean they can be accurate under ideal conditions, but if you're moving around a lot or sweating or the band is loose or you have dark or hairy skin then you might get a low reading. Better to use a real pulse oximeter that clips onto your finger. They're cheaper than an Apple Watch.
This looks very promising! I will look into it.

When I want a tabular view, I currently either used the pandas read_sql_query method or the PandaSQL module. That does work, and I often do want to use pandas and sql together (often back and forth, depending on the operation).

That said, I can see a use for this tool in my work - I'm often really just interested in interacting with a database in a more visually friendly way than the command line, and it would be great to stay with Jupyter rather than having to go through a completely different UI.

So, yeah, nice looking tool, and thanks for posting!
I guess the reason it didn't happen is that there is no need for it. Probably they laughing their ass off by profiting from it. Not sure how it works in the US but e.g. in Germany you have to pay taxes on crypto earnings. Sure you can just hold forever but what does it help you then?

We are so used to JavaScript SPAs taking a long time to load. People will Webpack it then use a tool to inline CSS and sort scripts. I find it easier and faster to use no loader at all, and manually sort scripts. The build process is less likely to break, because there is none, and it builds instantly, because there is none, it loads directly from the filesystem. Most modern browsers (even with IE11 included) support enough ES6 features that you can write your code directly in the common supported subset.[0] I had a multiplayer game with hundreds of hours of gameplay get on the front page with "loads in less than one second" in the HN headline.

I always heard this advice but didn’t know why. So I looked into it. Basically, the system Ruby is fine for running sysadmin scripts (as long as you don’t add gems or try to update it). But don’t use it for development because:

- the default location for gems is the system Ruby directory /Library/Ruby/Gems/2.6.0 so you will need to be superuser to install gems (and you really shouldn’t alter this folder)

- you could use sudo to install gems but that’s a security risk (gem installation can run malicious code)

- using Bundler is a best practice to manage gem versions and dependencies

- it’s best to start projects with the newest version of Ruby and the system Ruby is 2.6.3

- the pre-installed Ruby is deprecated by Apple and may disappear in future macOS releases

Network size increases competition to mine blocks faster, leading to demands for higher hash rate, leading to higher power consumption.

It'd have a similar role as gold. In cases state failure, you absolutely do have people trying to buy groceries with gold coins. But it's inconvenient, and people tend to run out of gold coins. So the incentives - when times are good - run toward normal credit systems like Visa & Mastercard, and hard currencies gain adoption only when times are bad.

Similarly, we've had folks transacting personally with Bitcoin in Venezuela and Zimbabwe. It tends to work out fairly well for them - at least their money holds value. But transaction costs in Bitcoin during the 2017 bubble were about $20/transaction, which makes it a pretty high-friction experience for groceries. There's a lot of market pressure to create other solutions (Lightning Network? Stellar? Local fintech companies?) for payments when Bitcoin costs $20 for everything.

With well over 100,000 apps in the Play Store alone, from companies like Grab, eBay, Alibaba and Betterment; as well as copious usage by Google's own apps like Google Pay and integration into the Home Hub, this is a pretty low risk even if you have a skeptical eye at Google's track record. It's more than paying for itself in reduced costs internally, even without any regard to its external value to Google.
It's really hard to see how BTC does not get outlawed by most governments. Since financial transactions are zero sum and provide no economic value, it's the equivalent of a giant methane leak.
