> Is Retool that useful? DoorDash thinks so. So does Brex. And Peloton. And Mercedes. And Tom Brad... Sorry I meant the NFL. Not sure Brady knows about Retool yet.

These claims, while true in a literal sense, always bug me in that they don't really mean anything. I actually work for Mercedes and it's so large I can't even see where my division starts and ends, let alone my area of the company (which is a subsidiary of a subsidiary!)

I'm sure a team uses it somewhere nor do I have any opinion of Retool itself. I'm also not speaking on behalf of Mercedes either. Just that it's a sort of Gell-Mann Amnesia feeling I get when reading that endorsement ;)
Where is my program creator dammit? Flying cars and household robots missing too. Everything is just like 1969, your "program creator" is some House Negr^H^H^H Estonian sitting by a Teletype.
There's a proof-of-concept file sharing protocol (Monotone? I cannot remember the name. Edit: it's monolith.sourceforge.net) that distributes numbers as xor of legal numbers.

Alice publishes a truly random string of bits, Bob publishes a XOR of Alice's string with an "illegal" number. Information theory says you cannot tell which is which (and publishing a random string of bits is supposedly legal) but you can still retrieve the "illegal" number by xoring Alice's and Bob's strings.
Many billions of pounds are being wasted on this. This failed app and system has had ten times the overall cost of the Mars Perseverance mission budgeted for it.
As a startup, I think it's important to employ passionate people because passionate ones could be turned into good ones but not the other way around.
Honestly, the only practical solution to this in my experience is to just buckle up and spend the hours/days it takes to learn the dirty corners of Bash properly. This doesn't mean you have to learn 100% of it, but it does mean you need to learn enough of it that will (a) serve your needs comfortably (instead of making you constantly have to hack around), and (b) give you insight as to what subset(s) to avoid unless absolutely necessary. Same goes with other tools, whether with warranted or unwarranted complexity (like git, Bazel, C++, etc.). Yes it's painful while you're still learning, but it's an investment that makes you more productive and just makes everything so much more tolerable afterward. If you never spend the time then you'll keep dying inside every time you have to deal with tools you don't like.
That was my point. You need Perforce or Git-LFS so it's very different than what regular developers are used to. When I see "how can you not use source control in 2021?" it's mostly from people that don't understand that you can't just do a "git init" and be done with it.

I'm involved in the indie gaming scene and not using source control is still pretty common as far as I can tell.

UE and Unity both have further issues that make source control complicated, as illustrated by the sibling comments.
I personally don't have any experience with this but just thought I would share what I found while researching this.

Not sure about using ML algorithm but you could look into “edge enhancement”. I think edge enhancement combined with a bit of tweaking of contrast, sharpness should give you good results.

Sharpening Filters is another one to look at. If you are looking to do this in an app, GPUImage library has sharpening filters. It might have edge enhancement filters too though I am not 100% certain.

Search for “edge enhancement online” for example for some tools. You can also look for their algorithms too. Photoshop and Photopea probably do them too.

Here’s some example I tested with an online image with edge enhancement. Your customers probably give you better quality and size images than this:

The quick summary here is that while a person is supposed to have only one Facebook account, that account can have an unlimited number of Facebook pages, which can all be set up to look like individual users, and can all comment, like, and post just like an individual user.

The article gives examples of these pages making hundreds of pro-government comments on various political posts.

Good for you, I guess. I hope it stays that way.

This was a December 2019 article:

E-bikes show distinct pattern of severe injuries: https://www.reuters.com/article/us-health-ebike-injuries-idU...

> "The authors analyzed emergency department data collected from 2000 to 2017 by the United States Consumer Product Safety Commission’s National Electronic Injury Surveillance System (NEISS), on injuries involving all three types of vehicles."

> "While people riding e-bikes were more likely to suffer internal injuries and be hospitalized compared to the other riders, powered scooter users had higher rates of concussion. E-bike injuries were also more than three times as likely to involve a collision with a pedestrian than either scooter or traditional bike injuries, the researchers report in the journal Injury Prevention."

Hence, this is why I recommend an airbag vest. While bones can heal, other things cannot.
> ) It's difficult to use as a daily driver even for experienced people. It's impossible for the average person.

Although true, this is a problem with software, which gets better every month. I'm sure within a year it's gonna be alright. (A year ago the phone could not even be charged while being powered on or receive calls.)

> 2) It's not a premium device with a big beautiful screen, lots of RAM, the fastest processor, tons of storage, etc. So it doesn't attract the non-technical enthusiast crowd.

Actually, it is in the world of GNU/Linux phones (the alternative being Pinephone). It is also powerful enough to drive GNU/Linux smoothly, play 3d games, videos on a big screen (which popular phone can do that?) and so on. It can also replace your laptop for most typical tasks.

> 3) It doesn't have brand appeal like Samsung or Apple. It's not consider a "status" item by the general population. So it doesn't attract a beautiful young fashion model who wants to be seen with an iPhone 12 Pro Max XL Super Duper.

Give it some time ;) It already has some brand value, despite a niche one.

> 4) It runs an operating system most people have never heard of - Linux. Most people know Android, most people know what iOS is, or have at least heard of it. The people I mentioned above don't know Linux. They especially don't understand what makes this brand of Linux "special".

People don't care whether they heard of it or not. Android runs Linux kernel just fine, so Linux is already popular. What makes it "special" is written on the official Librem 5 page. And it's not only for geeks: https://puri.sm/products/librem-5.

> 5) In order to this to eventually overtake the world, the entire world has to shift to a paid model for literally everything, because how else are you going to fund it? Everybody's exchanging data with everyone. Data about users. No exchange means increased prices across the board, for everything, because no data means no targeted advertisement.

GNU/Linux repositories work flawlessly without any ads and, moreover, have much less malware, if at all. It's not the whole world, but a large part of it nonetheless.

> Hell, you can barely do untargeted advertisement with no data.

This is how newspapers worked since forever.

Are you comparing "panels vs. solar roof", or "roof + panels vs. solar roof"? My understanding was that this being your roof (and thus replacing the cost of the roof) was the main point that makes it at least less unreasonable.

The lethargic govt "grant" took right around a month of my submitting a bank draft and the installation. then another month later the final installation of lightening arresters and such.

The way it is set up, you pay your deposit amount (around 30% of the project cost) via bank draft to the govt and they assign a local retailer/installer to install the whole setup, panels and reverse meter and inverter and once the govt gives them a green signal, their money is released.
That’s So Cringe! Why is everyone suddenly so embarrassed for everyone else?

I'm not sure this is the best advice. Providing more flexibility allows for the spontaneity of motivation that can help you escape a rut which is what the OP is asking.

This assumes that you can be instantly productive in the 3hr work blocks. If you can't get into a flow for the first hour, then you only have 2 hours, etc. And you start to look forward to your breaks.

Flow works best when you have open-ended working sessions. If you are making good progress - don't stop it for lunch. Grab something quick, and then have a larger dinner.
Frame-skipping is just a speed hack of skipping rendering every other frame or so, and makes games very unenjoyable to play. It won't help with input lag at all.
I use this hack as a matter of course, having internalised it aeons ago. Bash does lots of things better now but as others have commented it is still so fundamentally weird that an innate conservatism is often a wise approach, especially when one lacks the time (or motivation) to explore its "newer" features.
My thought exactly. An open source version could be nice in it's own right or lead to good improvements on other open source speech synthesizers such as Espeak. I think current TTS research/software is only focused on sounding nice and human. This is cool if you want to replace a human voice with something computer generated, but not ideal if you want an efficient speech output that can convey as much info as possible as fast as possible. Predictability is key here, I could proofread a text in Dutch (my native language) with ETI Eloquence set to English and just by the sound of certain letter combinations I would know if there is a spelling mistake, couldn't do that with any other "better sounding" synth.
Taking the same idea further, there are plenty of (possibly) illegal numbers that don't even have to be prime, just because an ASCII-encoded string of text can be represented as a number.

A pair of GPS coordinates with five decimal precision, written like 7.63941, -122.12825 is just 19 ASCII characters. So in ~400 characters you could have 20 such pairs. 400 ASCII characters being 400 bytes or 3200 bits, they can be represented by a number that's < 2^3200. What if the 20 pairs of coordinates are current locations of US nuclear submarines? That would make the ~900 digit number very dangerous from the US military's point of view.

400 characters is surely also enough for many other bits of highly classified information. Several names of CIA agents under non-official cover in China. A concise description of the purpose and capabilities of the X-37 spacecraft. The top item on the President's Daily Brief for today.

It raises some interesting questions about the legality of numbers, and what would happen to someone publishing one. What if I'm writing an article that happens to contain the nuclear-submarine-coordinates-encoding number? What if I'm writing about a debugging problem and I show a memory dump that happens to contain it? The actual probability of that happening is of course zero, but something tells me that anyone who did publish such a number would suddenly find themselves in the company of government agents very willing to overlook that person's rights.
It was barely a prototype, more of a proof of concept, as it couldn't lift anything much but itself. Also it was not just reusable (though not reused) but SSTO. And SSTO is almost certainly a dead end for chemical rockets. In part but not exclusively because aerospikes seem to be impractical, but also because fully reusable and inexpensive boosters are obviously working just fine. The case for sending a lot of deadweight up the gravity well is simply too poor, even if you could do it with great efficiency.
Aren't solar cells expected to lose efficiency to the point where they should be replaced after 25 years?

Hard disagree from me. Large TVs have gotten so cheap and movies are so expensive. We found one of our TVs on the curb for free, and it’s miles ahead of what we watched tv on when I was a kid. Who can afford to go to the movies on the regular but not afford a tv?

And I know, cheap TVs aren’t what you meant by “decent home cinema” but for many people a 60-75” tv with a midrange soundbar (or decent headphones) is plenty. Both those things can be had secondhand. Obviously below a certain income level it’s still not doable, but I can’t imagine being so poor I couldn’t afford a secondhand tv but still willing to drop $15 on admission then pay $8 for a popcorn.

What was the benefit of these flights anyways when you have a good rail and highway system?

> So an infinitely long but finitely thick cylinder would have one large (along) and one small (around) dimension?

Exactly. The mathematical concept behind this is the idea of compactness[0, 1]. A compact manifold always has finite volume. In the same way, a compact dimension always has finite length and this is what is meant here.[2]

Note that the converse does not hold: Not every dimension of finite length is necessarily compact. (The mathematical reason being that the metric tensor could become smaller and smaller ("fade out") towards the infinite ends.) But for the purposes of talking about string theory, you can usually equate the terms "finite length/volume" and "compact".

> Is "small" then always finite, but large can be large-but-finite or inifinte?

Yes, "small" is always finite (compact). As for "large" dimensions, I would say that's a matter of terminology and physicists tend to not be very precise with their terminology. It can both be large-but-finite (compact) or infinite (non-compact), depending on the context.

[0]: https://en.wikipedia.org/wiki/Compact_space

[1]: https://mathworld.wolfram.com/CompactManifold.html

[2]: This is also what string theorists mean when they "compactify a dimension": They take this infinite dimension and "wrap it around" a circle (of a given circumference) and end up with a cylinder or some more complicated object (depending on what they started with).
I would like to have a trained neural network that can generate Tolkien maps from existing map images and a filter for google maps or OpenStreetMap that can render the maps in Tolkien mode.
Agreed about chasing the beam. With a SNAC addon and a CRT TV, you can even hook up original light guns to the mister and they work prefect.
There are several past threads of this article but this comment about how the DeCSS illegal prime was created seemed the most interesting: https://news.ycombinator.com/item?id=1045394

This might be thought of as a human version of a covert channel: https://en.wikipedia.org/wiki/Covert_channel

E.g. publicizing the number and expiration date of Bill Gates' credit-card is illegal but what if we wrote a text commentary about Shakespeare's Hamlet that when SHA-1 hashed, it gives you that same information? Yes, it would be very computationally intensive to generate a plausible literary text but it could be done. Or one embeds Bill Gates credit-card number as "transactions amounts" on Bitcoin blockchain.

The theme is the same: find a "legitimate" information channel to transmit illegitimate data. This then allows the philosophical arguments about information:

- How can commentary about Shakespeare be illegal? It's education!

- How can you censor transactions on the bitcoin blockchain? There are already 100,000+ copies of it on nodes around the globe! And so on...
Can we just finally let it go with Pocket? Who cares? Just disable it if you care.
I’m almost certain the default encoding for reading/writing files in Java is UTF-8 and similarly for the source files. I don’t think I encounter wide char data much really at all day to day ...
The `lazy` storage class turns out to be unreasonably hard to reason about.

`alias this` in class objects turned out to make no sense. When people have problems with it, I just sigh and say stop using `alias this` in classes.
And that’s why I believe self driving cars will kill public transport as well as short leg flying. I already prefer the Tesla autopilot on longer highway drives to trains. As soon as I can really take my eyes off at the motorway I have not much reason to fly anymore (before Covid I had 30-50 flights in one year), except long distance.

A quick google shows the app will cost c£35 million[1], while the overall cost of the Mars Perseverance programme is $2.7 billion[2]. 10 times $2.7 billion is $27 billion so you are out by a large factor.

I find the very idea of XSLT simply pointless. It is fundamentally structured around templates and doesn't accept anything beyond XML (even in XSLT 3.0, where you can have an initial template but can't get rid of it), making it cumbersome for general programming. It is also very verbose so it is not suitable for scripting as well. For XSLT to be useful you need a complex enough transformation (so you actually want templates) and nothing else (so you can avoid general programming); that use case would be pretty rare.

It's worth distinguishing money, which is created by government regulation, from other forms of wealth and stores of value.

The reason that money has value is because the government will demand a certain amount of it as taxes. The amount of money created -- whether by "traditional" mechanisms such as interest on sovereign debt, or more ad-hoc helicopter deposits -- is balanced against money to determine the value of a currency.

Bonds are a temporary removal of money from the economy. You give the government $95 today, and they promise to pay you $100 in 10 years[0]. Whether that's a good deal depends on the expected inflation rate.

Gold is therefore not a bet on the presence of inflation, but on the (predicted) relative ratio of inflation vs same-currency sovereign bonds. If the dollar is inflating at 3% and a 10-year treasury yields 1% then gold is a great investment, but flip those numbers around and it changes from a currency hedge to a plain commodity.

[0] Or, if you're buying a German bund, you pay $101 today and get back $100.
Correlation =/= causuation.

Probably its caused by e-bikes being far more popular amongst the elderly. Here, in the Netherlands, typically only the elderly ride on e-bikes.

Also, e-bikes allow the rider to go far faster than they would normally do. Probably more fair to compare moped vs e-bike (and corrected for the age of the driver).
That's false, [ is a bash shell builtin (it's also a coreutils program, but the program is not called unless you specify /usr/bin/[ or use a shell that doesn't have it built-in).

Strong agree. The thing about Maven is that it requires us to build a project model, then it executes the model. That means it's possible to reason about what will happen based off the completed model. It doesn't matter whether the model is encoded in XML or generated in code: the important bit is that we (and our tooling) can inspect the model.

Gradle _almost_ does the same, but it allows execution of arbitrary code in too many places -- like with parsing Perl, we can't discover the model without also executing it. Hence the trap.
Disclaimer: this is not an endorsement but a statement of fact.

There is no should or shouldn't. This is power, and those with power make, change, and break the rules as they wish.

Just consider that the US flagrantly violated the Iran deal, and nothing punitive happened.

Sure, there's an NPT on paper, and yes we have a far smaller stock pile of 4k nukes... but how can the US get away running nuclear tests in 1992, 30 years after an NPT which "obligates the nuclear weapons states to liquidate their nuclear stockpiles and pursue complete disarmament." How did the US pull off nuke research in 2003 or actually building new bombs in 2007? Why did no one else start pounding their chests demanding sanctions or IAEA inspectors?

Simple: The "rules" don't apply to the US or most major powers.
This article is about the app though - which was £35 million.

Why add in 36.9 billion of other costs? (other than to distort it to make it look much more expensive than it is?)
