A recent survey of American values indicates that patriotism, belief in God and having children all rate much lower than they did 20 years ago.

Gosh, one wonders what could have happened? Maybe two decades of pointless soul-rotting stupid wars, all supported by the most patriotic and pious among us? That has certainly sapped this correspondent's patriotism. (His piety, though, something else sapped that...) Next you'll be telling us that trigger-happy crowd-murders are more common, and we'll think of all the wedding parties, funerals, open markets, etc. we've incinerated in the Middle East. It's as if chickens... come home to roost!

Do you know Epicureanism?[1] Basically what you're describing.

> Epicurus believed that what he called "pleasure" (ἡδονή) was the greatest good, but that the way to attain such pleasure was to live modestly, to gain knowledge of the workings of the world, and to limit one's desires. This would lead one to attain a state of tranquility (ataraxia) and freedom from fear as well as an absence of bodily pain (aponia).

It's a good way to live.

I don't think so - it's deeply misleading to say it's powered by gravitational collapse, which is tiny in the energy budget. They are formed by gravitation collapse and gravity is necessary for their function. A fire wouldn't start without a match, but you wouldn't say they are powered by matches or the air.

An omniscient god can guide random processes as it wishes. Or it can create a system where the desired outcome will come to pass, without controlling every detail. Like how each molecule of water moves randomly and unpredictably, but the river flows downhill and to the ocean.
Korean grad student here. That was actually true for Korean college students when things were prosperous, but since the recessions (one in 1997 and another one in 2008) things have gone worse. There was a time where if you entered the top universities you almost automatically had a decent job, but nowadays students know this isn’t the case anymore. Nowadays even the students in the top universities take pressure with maintaining their GPAs and English exam scores, so I think the situation is a bit different than Japan (although I still think US colleges have more intense workloads, from what I’ve heard...)
If you enjoy researching and being creative, then maybe you can experiment with some online koans, watching tutorial videos, an online course or even coding competitions to get more exposure to how developers solve various types of problems differently. You might see some patterns that you understand and help you develop.

I personally learned a lot about problem solving from trying different language paradigms: being forced to tackle things from a different direction - so you could try some ClojureScript or golang (if you want to give the backend a try).

If things still don't click, then there's various different roles in software projects, the bigger the product the more diverse the roles: you can probably search a job board for "software" and see what comes up if you want to stick in the industry and get an idea for what else there is to do.
Dark matter is technically anything that doesn't radiate, but often it's meant to refer to WIMPs -- weakly interacting massive particles.

Now WIMPs are basically what it says on tin. We know they don't interact much, with themselves or anything else, because the rotation curves of the galaxies implies there are large halos. This means there's little to no friction, as otherwise the majority would fall down to the galactic cores, like normal matter does.

We assume they're a separate type of particle from anything we know, as otherwise that shouldn't be possible. We know they're massive, as otherwise we'd see them in particle accelerators... well, we'd see the missing mass at least.

Then, what are they? Well...

Probably a lot of things. The "dark matter sector" outweighs visible matter by a lot, and there's no reason that should be just a single particle.

But anyway, think of graph theory. You can map particles to nodes on a graph, and the fundamental forces to edges.

Not all particles are connected by way of all forces. Electrons lack color charge; neutrinos lack basically everything. (Even when there's a connection, connections can be of varying strengths.)

Dark matter is matter that lacks any connection to the other particles, except gravity.

(Could there be particles that are unconnected by gravity? That gets speculative, but probably not. Gravity is special.)

Ah, but-- there might be more than one dark matter particle, and forces connecting them that won't touch our type. For the most part we know this isn't true, since we know they don't interact with themselves either, but this is only to say that most dark matter can't be doing that.

There absolutely could be dark-matter stars, or stranger things.

... This is purely speculative, though. Good for fiction, but the only kind of dark matter we know exists is the WIMPs.
Review of harmful apps on Google Play in August: 204 apps with 438M+ installs
It takes fractions of a penny to make something with electronics last several years longer than just the minimum 2-5 years. Yet the device manufacturer chooses the short-lived version.

Consumers should demand devices that have a long life and can be easily repaired ideally by yourself. As long as there are rapid technological advances, consumers do not care about the lack of longevity and the resulting waste.

Our parents had long-lasting household appliances, radios and TVs that could be repaired. It was considered standard to receive a circuit diagram with your device.

1. enabling cleverness enables creating tool to manage complexity, and hopefully, to manage it with fewer people needed

2. Google "sets the intellectual trend/fashion", whether we like it or not, their attitude get copied... there was quite a bit of experimentation in the 1995 - 2015 decades, we saw stuff like real macros coming to mainstream programming languages (Julia, Scala, Rust), we saw advanced type systems become liked and used (see even TypeScript which basically supports "poor man's ADTs" now), but the "new wave" which seems inspired by G's language design trends seems to be all about throwing it all away, we're scared s'less of complexity and unmaintainabilty that using anything more that string substitutions for code generation when we really-really-really have to seems heresy.

The trends seems to have creeped even into languages like Haskell where nobody's talking about template Haskell anymore and everyone or adding dependent types or whatever, it's all about focusing on package managers and limiting new features and building more tools... Python has a growth spur with 3.0 - 3.6 but that's also freezing in a way, no bold new additions coming without endless discussions.
'Far out in the uncharted backwaters of the unfashionable end of the Western Spiral arm of the Galaxy lies a small unregarded yellow sun.

Orbiting this at a distance of roughly ninety-two million miles is an utterly insignificant little blue green planet whose ape-descended life forms are so amazingly primitive that they still think digital watches are a pretty neat idea.

This planet has – or rather had – a problem, which was this: most of the people living on it were unhappy for pretty much of the time. Many solutions were suggested for this problem, but most of these were largely concerned with the movements of small green pieces of paper, which is odd because on the whole it wasn’t the small green pieces of paper that were unhappy.

And so the problem remained; lots of the people were mean, and most of them were miserable, even the ones with digital watches.'

The speed is basically an excuse for an expensive car. Due to reasons (which I don't want to delve into) there are people who can and want to spend an absurd amount of money on a car, but if you just give them a perfectly fine people mover with more "gold and eagles" (sorry for the futurama reference), they'd feel ripped off. The car has to offer something that a less expensive car can't and that's where paper speed comes in. Even perfectly irrational purchases require some element of rationality.

PS: if you just want the joy of speed, the fix is not a faster car but a vehicle that allows you to experience the speed better, one that isolates you less from the road. A light roadster, a motorcycle, a roadbike (quite a few people actually "graduate" from a motorcycle to a roadbike because perceived speed is higher in lycra and with legs doubling as shock absorbers)

Apple is super successful with un-repairable products.
With the latest iPhones they try to prevent you from going to a non-authorized repair service to exchange the battery, a part that is known to deteriorate after two years leading to decreased performance. Maybe people do not care because smartphones have been rapidly improving in the past.

What makes you think that if people manage to misimplement CSV parsers and generators they are not going to misimplement other formats? At least with CSV it’s always easy to implement some sort of heuristic that splits the rows correctly.

What makes sense is that the number of bugs tends to end up proportional with the amount of code...

If a powerful language allows you do the same thing with 10x less code, you'll also have up to 10x fewer bugs (in practice maybe only 2x fewer, but that would still be huge).

> Again, there's a difference between a physical thing vs an accurate representation of a thing by other physical means.

A late reply, perhaps, but:

- Does the physicality matter all that much here? For sake of argument, let's assume that I have an infinitely powerful computer, which simulates a brain perfectly, down to the last atom. Would the thing inside my simulation not be conscious, and if so, why not?

> As a thought experiment, would it be possible to create consciousness using pen and paper calculation? Perform the same calculations by hand, multithread it by using billions of people performing the same symbol manipulation we would have otherwise performed on the computer.

I don't see why not, to be honest. That is: given enough computing power and enough knowledge on how it works.

> I would argue that it's not the act of manipulating symbols that gives rise to consciousness(since it's the only thing the computer and paper methods have in common), rather that something qualitatively different is happening in the brain.

I must admit: I'm a Hofstadterian in this; I agree with his conclusions that consciousness, as we describe it, is an emergent property caused by the act of manipulating symbols representing ideas and concepts in a self/circularly referencing manner.

Performance of JPEG Resize On-Demand Application with CUDA MPS on Linux
The "Disk Doctor", as shipped with AmigaOS versions 1.2-2.04 was both a crude and cruel tool.

Its primary purpose was to "restore" a damaged volume to a state which enabled read-access, allowing you to copy the data to a different volume. At the time most users (myself included) viewed it as a repair tool which should have been able to restore a damaged volume to operational state again. You needed a second floppy disk drive to be able to copy the data to a different disk which was a rare thing to have in the old days. So we settled for what should have been a "fix in place" repair operation, but in reality "Disk Doctor" never left a volume in a better state than it was before, even if the file system structures had been sound to begin with.

The reasons why the "Disk Doctor" was so bad at repairing anything are legion.

For example, if a track could not be read because of a flipped bit or physical damage, "Disk Doctor" would attempt to restore the entire track to a sane state by reformatting it (physical low-level initialization). The "Disk Doctor" uses the same buffer for reading and writing data, which means that when it reformats a track, it will (as a side-effect) write the data that was last read back to disk. That data was written to a different track, and if it happened to contain file system data structures, then "Disk Doctor" would later pick them up and try to make sense of them: it was basically "fuzzing" itself.

Part of the diagnostic operations performed prior to "repair" was to detect damaged or deleted file system structures, such as files or directories which no longer had a valid parent directory ("orphans"). The "Disk Doctor" would gather these and add them to the root directory. It did not check if there already were files or directories present in the root directory which shared the same names, which could have the effect of corrupting the root directory. You might be able to list the root directory and find several files with the same names stored in it, but accessing these would only go as far as the first entry in the directory entry list.

When trying to recover the "orphaned" directory entries the "Disk Doctor" made no attempt to verify that the files and directories it added to the root directory were structurally sound. You could have ended up with fragments of files which were deleted ages ago and whose parts had been partly overwritten since they had been deleted. These broken file data structures could reference data and metadata blocks, which in turn would then break the disk validation process.

Looks like a “three strikes” law, which imposes a mandatory heavy (in this case, ridiculously heavy given the offenses) sentence after a certain number of felony convictions:

“After this conviction under La.R.S. 14:67, Mr. Jackson was sentenced in accordance with R.S. 15:529.1 A(1)(c)(ii), which states in pertinent part:

If the fourth or subsequent felony or any of the prior felonies is a felony defined as a crime of violence under R.S. 14:2(13) ․ the person shall be imprisoned for the remainder of his natural life, without benefit of parole, probation, or suspension of sentence.

After a sentencing hearing at which the State proved Mr. Jackson's multiple offender status, the trial court simply stated that “because of the specific provisions of the law ․ the sentence must be ․ life imprisonment without benefit of parole, probation or suspension.” Mr. Jackson has prior convictions for simple burglary in 1991 and in 1986 and for simple robbery in 1979. Simple robbery is listed as a crime of violence under La.R.S. 14:2(13).”

Ask HN: Is there any large scale product/startup that uses Node.js primarily?
- powerful features -> less code to do something -> less bugs because less code

- powerful features -> more general abstractions -> more code reuse -> less new code written -> less bugs

It's not that simple, but it's good to start with the core assumption that less code -> less bugs and what more powerful languages offer you is ability to solve problems with less code while at the same time keeping that more compact code readable.

Or maybe big software-focused companies like G don't see "# of LOC" as a liability and don't try to reduce it while at the same time as trying to do more? Is this the core difference between a large corporation and a small startup that tries to do more with less?
>Trabis had no fuel gauge, air conditioning, turn signals, or brake lights, and could only reach a maximum speed of 62 miles per hour.

how can they have no fuel gauge? I can sort of understand how it is still operational with the rest, but does it just stop and run out of gas at some random time? does it start sputtering long enough for you to realize you need to make it into another gas station?

this one has me stumped.

This sounds interesting to me! I actually thought about something relatively similar with the intention of creating js-based renderer to make it web browser compatible. I was also contemplating the idea to put semantic data into a separate structure, similarly to schema.org data in json-ld format. While this is probably worse from the editor point of view, the advantage would be more clear and more human readable content since the semantic tags would be omitted. This could also save some bandwidth if client software could fetch only the part that it needs (for instance if a given reader does not support semantic tags parsing it could download only the main content, while search engines could download only the semantic part).
The problem is that thinking about that for a while is all that I've achieved so far :)
