Perl 6Raku.That's the point. Raku isn't Perl anymore (despite it's first RFC saying Perl should stay Perl) but a horrible mixture of everbody's favourite feature. While Perl 5 is actually a fairly minimal language with a bit too much syntactic sugar topping.

How does it interact with floating point stuff? Explicit conversion?

Exact arithmetic using rational fractions seems nice, except it tends to run into problems with large numbers of digits required. It's also a lot more complex once you start using higher functions than simple arithmetic. I've seen solutions for that which attempt instead to use generator expressions which can spit out as many digits as you ask for; they're in turn based on more complex arrangements such as continued fractions or 4th order tensors.
That stuff tends to be slow. More the sort of thing that you use to validate a fast floating point solution than anything else.

@dkf You use floats if you need the performance. 99% of the time you don't, especially considering you're already using Raku. Better, at that point, to be using a system which considers 0.15 + 0.15 to be equal to 0.2 + 0.1.

One of the other options is to implement decimal floating point. There's even an IEEE spec for it, but the Wikipedia page is probably an easier place to start when just reading about it.

@Dragoon Slashdot linked to this article. Dutch authorities also detected it. Source seems to be from western Russia. Western Russia however hasn't detected any problems with their powerplants:
“Both stations are working in normal regime. There have been no complaints about the equipment’s work,” Tass quoted him as saying. “No incidents related to release of radionuclide outside containment structures have been reported.”
(Or at least nobody bothered to report it. Or it's not from a powerplant.)

Rational numbers are somewhat nice, but to a reasonable language they can be easily added as a library.
I've stopped caring about it looong ago, but what I remember it has lots of tiny features with the traits and strange type combinations that sort-of-do-what-you-mean until you leave the well trodden path and find needing to actually understand them.

Decimal floating point is good for financial, because accounting generally defines rounding to specific number of decimal digits. But it won't help with division – you still have some divisions that are rounded.

The things that work very well are integers, binary floating point and binary fixed point. All provided they fit to the natural bit widths of what the processor implements. The tale of higher functions is more complex though, and that's where the quality of implementation of your math library really shows. Different processors implement different parts; basic trig functions are common but not universal. (We've got a chip under development that instead includes accelerators for
ln()
andexp()
, which are hugely more useful for our application than trig.)When going outside the area served by simple binary numeric types, either you're doing financial work (for which using either decimal math or integer numbers of cents works best usually) or you need slow but correct results for validating faster algorithms. The various arbitrary-precision algorithms focus on that latter use case.

Well, there was that other time when suddenly, wild nuclear readings appeared. Soviet said there was nothing wrong. And it definitely wasn't form them. But it may be old crap that's gotten from some rusted up old nuclear submarine, lord knows Soviet left enough of those around.
-
@Carnage I assume they have access to the same kind of monitoring, so the "we don't know nothing" seems unlikely. If nothing else, they should have detected the increase in radioactive particles themselves, and if it really wasn't them, they would be asking questions too.

I agree, they were very careful with their wording about nothing having been reported.

Dissolve e-waste, harvest gold
So far so good
profit.
Current spot price of gold is around $1775/oz. Is the cost of the e-waste, plus the cost of the polymer, plus the energy cost of retrieving the gold from the polymer, plus the cost of disposal of the rest of the stuff you don't care about, low enough to make it actually profitable? :skeptical_face:
-
@Mason_Wheeler E-waste is "free", potentially negative cost, though you do still have costs associated with acquisition and storage. The costs of retrieving the gold from the polymer look to be low, as it's just condensate out of a strong acid. Maceration costs, disposal costs, and separating gold-polymer complexes from the slurry of fiberglass, resin, plastic residue, acid/alkali, etc are likely to pose problems though.

You hire good PR/lobbying company to bully the state with eco/climate scare campaign to pass laws that:
- force people to segregate e-waste for you
- force garbage disposal companies to transport e-waste to your doorstep
- force the same garbage disposal companies to take care of your waste
- force municipalities to guarantee minimum prices (or just minimum yearly profit, why not)
It's not about the technology, but how you apply it.

In this case, it found the radioactive isotopes Cs-134, Cs-137 and Ru-103, which are produced from nuclear fission in reactors.
The CTBTO has said the isotopes are “most likely from a civil source”. The Dutch National Institute for Public Health and the Environment has said this suggests damage to a fuel element in a nuclear plant.
So it's not a warhead, allegedly.
Although, , it could still be a dirty bomb. ...If someone blows a "dirty bomb" in the middle of Russia, and their threats didn't make the news, will anyone ever know? And does it even matter?

Another great example of quality 21st century
click-baitingnews reporting:Article title:
Scandinavian countries detect nuclear particle emissions from Russia
Article content:
Nuclear monitoring stations in Sweden have detected radioactive particles suggesting a nuclear incident in Eastern Europe.
[...]
The possible area of contamination to the east covers areas of Sweden, Finland, Estonia, Russia and Latvia. Contamination from the west is less likely, with the possible area covering a small amount of Denmark.So yeah, you have no clue if the source actually is in Russia or rather in, like, half of the rest of Europe, you just gonna pretend you know because it has that nice "OMG Russia+Radioactivity :headless_chicken_screams.mp3:" general panic effect.

@Bulb But then you have to remember to type those everywhere. Rationals should be the default, with floats used for performance. Which is how it is in Raku; to get a float, you just have to use scientific notation and you'll get one.

That's basically how the masking actually works.
-
@dkf More or less.
The silicon is heated in the presence of oxygen to form a thin layer of SiO2. A photosensitive organic polymer is applied, which is then exposed to UV light through the actual mask to form a pattern in the photoresist. After washing away the part of the pattern that was (or wasn't, depending on whether it's a positive or negative photoresist) exposed to UV, HF is used to etch holes into the SiO2, which becomes the mask for the next step in processing the Si underneath. The SiO2 is then removed with HF (unless it's one of the later stages in the process, in which the SiO2 is used as the insulation between layers of aluminum wires that are deposited to connect all the Si transistors together), and the sequence is repeated for the next step in the process. Still somewhat simplified, but pretty close.

@acrow Something Awful forums member Drastic Actions did a more in-depth analysis, and determined that, other than "run arbitrary unsigned blob downloaded from insecure HTTP server" on Android (which is blocked by the OS), all of the things the guy on Reddit found either had an implementation of
throw new NotImplementedException()
, or weren't called by the app and hitched a ride with library code, or both. The server side is a dumpster fire, but the app itself doesn't do anything beyond what any other mobile app with advertising does.
-
@TwelveBaud The Twitter post claims that the other stuff was observed in HTTP traffic before the app upgraded to HTTPS in a later update. Also, the OS level crackdowns on executing random downloaded stuff always get erected after someone is caught ******* the cookie jar.
I don't dispute that the app code itself may not be implementing spying functions. After all, those are best left to the doctored libraries. Remember the trojan'd Apple SDK version, spread in China a few years back? The Great Chinese Firewall makes access to SDKs from original sources problematic, so a lot of people fell for a malware laden pack.
So I can well imagine the government stepping up to provide domestic hosting to the same. And ban competition, for "public safety". And maybe add some government surveillance to the SDK libraries. If the app will also be used inside China, there is even an incentive for using the government-altered version; better language support.
