The headline is true under the assumption that music downloads are only for listening to. But it is a tremendous loss to forget about downstream processing, e.g. remixes &c., which will want extra bit-depth:

> An engineer also requires more than 16 bits during mixing and mastering. Modern work flows may involve literally thousands of effects and operations. The quantization noise and noise floor of a 16 bit sample may be undetectable during playback, but multiplying that noise by a few thousand times eventually becomes noticeable. 24 bits keeps the accumulated noise at a very low level. Once the music is ready to distribute, there's no reason to keep more than 16 bits.

192 kHz less practically useful, but for the time being is still a useful signal as to the target audience.

If all that mattered were playback, lossless 16/44.1 would be almost as silly compared to distributing only with lossy compression. The space savings of, say, 128 kbps opus, surely outweigh the few audible difference that nobody will even notice without a comparison, right?
Thanks for sharing your insights!

>There are a few places in POSIX where the parser has to be invoked recursively

In your examples, we have the runtime invoke the parser as necessary. The parser doesn't know about the runtime. For alias resolution, we have a callback function, which hooks into the runtime but is pretty thin and abstract.

Thankfully, this is non-POSIX so mrsh doesn't have to worry about it.

Yes.

If you choose to dedicate the bulk of your waking life to creating wealth for your employer, you should be compensated, at a minimum, well enough to feed, clothe and house yourself.

or there should be something like UBI in place to allow employers to decouple the cost of keeping their employees alive from the cost of doing business.
Instead of addressing the substance of my argument you are instead attacking my familiarity with the particulars of the the tools and techniques used to do contemporary reverse engineering. This is a logical fallacy known as the Courtier's Reply:

>And then there's education classes. They're all jokes, and the "research" is so BSed it's not even funny.

I knew someone who was taking these classes, they said the same thing. One time I saw a great takedown of education studies, but I could never find it again. Do you have any examples of or links describing the phenomenon how atrociously bad the education of educators is?
I deleted my Facebook. Two things I would’ve liked:

- a tool to add exif location data back to my images. In the export the image metadata (like location) is in a separate file. I ended up writing a quick script to do this.

- a tool to message people in messenger my phone number and email. I ended up doing this manually, but it’d be nice to have an automated solution.

It is sensible. First, deductibles are applied to the bands, like everywhere else. This calculation is done over your yearly salary, in March of the following year. You then pay income tax in August.

However, in order to minimize the amount due in August, the government captures an estimate of your income tax every month (before you get paid).

It is this estimate that is designed to be simple, and applies deductibles to the whole salary. There's no harm: If it happens to capture too much, you'll see your money back next August.
It's really not that bad. Keep in mind that you typically will only go this slow for the last 15-60s of your drive. Before that you will likely go faster than on a typical drive in the US. European speed limits and especially German ones have a lot more range then US speed limits. To be that makes for a more deliberate and fun driving experience. It also turns out to be safer if you look at fatalities per mile traveled, even including the Autobahn which seems to be unfathomable to most Americans.
Seems reasonable; grades are only partially a function of raw potential — effort plays a huge role as well. If a student is good enough to get an A-, I see no reason why demonstrating a certain amount of additional effort (extra credit) couldn’t get her to an A.
Larry's third day on the job: Let's buy all our competitors and raise prices 5x and get rid of independent car repair shops and make Bluetooth and anything besides AM radio an ad on for the car stereo that's $5000 extra and licensed per unique phone you pair with it. You also can no longer plug in your car at home without an annual license fee and priced per watt of charger output and how many different cars will use it. You also have to pay an extra charge per pound of passenger and luggage in the car over 50. The car won't start if it detects you're overweight.

The article sites some hard reason here but then argues them away: the Mongols sacking of Baghdad and the Spanish reconquista. I wonder how Europe would look like today if somebody had sacked Italy during the renaissance. In my book Europe was just lucky that it was shielded from significant disruptions (relative to the rest of the world) during the high and late middle ages due to geography and partition into competing centers.

The thing is, this is clearly for marketing purposes in the end. The approach is complex and sophisticated, but certainly not novel. A good architect in any decent interview should get to a similar solution. This must be read through the lines: this is an attempt to try and change their bad PR cycle.

I'm not saying the parent comment is absolutely essential, but I'd rather see that instead of people using this to change the conversation from central flaws in Facebook's data practices, business model, and ethics in general. This may sound a bit harsh, but at a certain point you have to really consider what giving publicity to a group gives them versus the inherent value of the paper.
Most people wouldn't be able to cut it in software dev, whether they did the 3 month bootcamp or even if they managed to pass a 4-year university program. 99% of the time, Little Jimmy's 4th grade English teacher would have a snowball's chance in hell as a professional developer.
Well, people have been known to hold in their brains information pertinent to their trade. Professional training helps, too. I can only guess the extent of what a mathematician, a physicist or a medical doctor must remember to be successful in what they do.

How do people manage scripts to be used in such niche shells? I started using zsh at work recently, while I quite enjoy the shell experience it is a pain to rewrite all bash scripts to zsh or add lines of codes for compatibility. Any pointers?
The NHTSA side impact ratings are considered outdated and inadequate, which is why I linked to the newer IIHS ratings above. The Crown Victoria is not a safe vehicle in a side crash compared to more modern designs.

That parent is an ass. Having grown up in a family where my parents deferred to teachers over me, even when the former was wrong to the point of harassment, however, it’s an understandable instinct.

Administrators don’t protect children. Boards don’t protect children. That only leaves parents, unchecked. If students had proper means through which to pursue grievances against teachers, I’d hope these parental impulses would recede.
XCOM no doubt. I once lost a veteran ranger and I was bummed for days. He was mind-controlled by the enemy and a panicked friendly shot him. Tragic.
Montreal's underground is a pretty strong counterexample. The pedestrian "tunnels" have retail, dining, etc on the sides, with strong artificial lighting and skylights when possible. It's closer to a mall than a tunnel, and they're quite nice.

Yeah making Oil more efficient is an open problem. I've been going back and forth on the whole OVM thing (long story). I think that's the right idea, but it's not clear how long it will take.

But I think the efficiency problem is easier than the problem of running big hairy unmodified shell scripts, which I view as essential to replacing bash.

That is, it's easier to make something that works efficient, as opposed to thinking you have 60% of a shell and really having 20% of one :-/ That was the case for awhile, but since OSH can run many real programs, I'm pretty confident in its feature set.

I don't see sh as a losing battle. I actually think it's quite good for the niche it aims to serve - a niche that very much exists, sh is a square peg and should only go in square holes. I think most folks have had their impression of POSIX shell tainted by bad shells like bash and - sorry - oil encouraging complex, non-portable shell scripts. I intend to write more blog posts in the future helping people gain a closer understanding of POSIX shell and how/where it's useful and how to use it.
I wonder what's going to be more effective - building the wall, or paying the people employed to guard the border?

Almost off topic: that to me was one of the most interesting learnings from playing Second Life. Because you could teleport anywhere, location only mattered for having a view. There were hardly any interesting clusters of structures. This made it hard to organically discover fun stuff. If the world hadn't had teleportation from anywhere to anywhere but some kind of portal system, I think it would have been way more interesting.

The student demonstrated an adequate amount of effort to achieve an A-. Any "additional" effort should have been expended at that time. Alternately, the student can put that effort towards future assignments.

If the teacher wants to give out opportunities for extra credit (maybe because they feel the class is particularly challenging in general), they can do so. But students and parents are not entitled to extra credit, particularly those who already received a very respectable grade.

(I realize that for certain colleges, an A- isn't enough, but inflating everyone's grade doesn't help the situation.)
Remittances without high fees.

I think as entropy becomes very inefficient to produce (difficulty multipliers increasing on crypto as the network expands...) it will become more clear that the expensive part about sending money internationally is trusting all parties involved.

You pay VISA/MASTERCARD a 3% fee because you trust them to protect your account in the case of fraud. Moneygram takes 2% of all transcations over $900 because you trust them to move money from your account to the recipients account without losing it.

Even in computer security, you have to put your trust in something. Somebody picked cryptography and high numbers of CPU cycles.

Anyway, you asked what problems crypto could solve, and I guess my answer is, maybe it will cost less to send money around the world. As it turns out, there's not necessarily a way to make it free.
Unfortunately I don't, but I'd love to find that link you mentioned.

As to my own experience with them, they're all very generalized and often don't actually test how well a student has learned something. I see these a lot with tech use. Calculators help test scores, but do students actually learn how to do the math? No, take away the calculator and see; often they can't even do basic multiplication without their fingers.

Or you'll see studies generalized from groups of 10 students, without taking other variables into count. I remember one where 20 kids improved after a certain strategy in an upper middle class private school. Authors then said this is the wya to do things and it should be implemented in lower socioeconomic class schools too.

And then the results often aren't meaningful and often feel forced, and really depend on how students feel on a given day and such... A student can easily bomb a test if they couldn't sleep the night before, and that score shouldn't show that they didn't necessarily learn with the intervention tested or whatever.

And that's just the studies. The actual classes are worse. I've learned nothing about education theory, and it's mostly just random teachers pushing their philosophy of teaching on us, or spouting off the research that agrees with it. And half my classes have been irrelevant. I teach high school math/science, and at least half my classes have been solely dedicated to elementary school apps/content. The one sole HS class I've taught was a joke where the teacher just went into how good dual credit was and how all HS should basically become community colleges... Without realizing that it isn't that way everywhere (our school's, for instance, is a joke and half of them don't transfer to other schools in-state).
Probably mostly the latter. The headphone adapter with recent iPhones measures remarkably well for such a tiny device: https://www.head-fi.org/threads/what-is-the-sound-quality-of... (scroll down a little for lots of geeky measurements).

It's hard for our brain to comprehend that such a tiny gadget can sound so good, so I suspect that accounts for a lot of the perceived difference. Also, some music can sound better with a poorer output device by e.g. smearing noise in the treble or rolling off excessive bass.
My experience corroborates this.

I worked at two small ISPs, each with a fiber network spanning a few US states. They had their own databases to track this information, but as far as I know there was no central database. One of them used OSPInsight backed by a self-hosted SQL Server database. I don't know what the other place used.
I'm asking around about that. In a simple contract dispute I believe you are right. If you have damages due to criminal activity it may not fall under the terms of a simple contract dispute.
Many of the things that people want to use smart contracts for can be implemented using a model involving some degree of trust between vetted participants. Anything involving a distributed value chain for an industry, for example.
Teachers should stop assigning tasks that necessitate parent participation, then. I was assigned to write a novella in sixth grade, for crying out loud. I like creative writing now, but I didn't back then, and the assignment sure didn't help.
Serious emotional anything, is hard to do i would argue. People react so differently to these things that you really have to distill a piece of the human experience, and present it in a novel way.

I would urge everyone interested in such a story to play "Brothers: a tale of two sons", which might have been some of my best 2-3 hours of gaming ever. Presenting it on this context might spoil some of it, but go in without any judgment or preconceptions and you'll have an experience that sticks.

I don’t pay a fee on my credit cards, the merchant does, and in case of fraud I can issue a chargeback to boot. As long as I pay my balance each month, my credit card is free, plus generating rewards. That’s almost the opposite of cryptocurrency, where far from being able to tackle fraud, it makes theft or loss nearly impossible to remediate. A credit card is also one of the easiest things to use, and all of the hard work on security is undertaken by merchants and the credit card issuer.
How to get an ex girlfriend attracted to you again
In the real world, you don’t get a chance to get “extra credit work” when you don’t do your job at the level the job expects of you.

Why should students be coddled instead of being prepared for the real world? I have a high school student who is always getting better grades because of “extra credit” and “make up tests”. I cringe every time he does it.

So what? You're going to have off-by-one errors no matter what convention you adopt. Python glosses over it by providing the alternative syntax x[-1] for what you would otherwise have to write as x[len(x)-1]. But it's at least as valid to provide alternative syntax for inclusive ranges. And logically, if the first element of x is x[0], the last element should be x[-0], not x[-1].

Half-open intervals are appropriate when you're thinking of them as subspaces of a continuum. When you're thinking of them as subsequences of discrete elements, closed intervals are usually more natural.

Ruby is the only language I know that really seems to have tried to address the problem, providing different syntax for every way you might want to take a subsequence from an array:

x[5..8] # elements [5] through [8], including [8]
x[5...9] # elements [5] through [9], excluding [9]
x[5, 4] # four elements, starting at [5]

If you were working in pure, pencil-and-paper mathematics, you'd choose whether to index a particular sequence from 0 or 1 based on what made your formula look nicer. Both are common. But that's not an approach I'd suggest for a programming language.
PoW will centralize towards cheap energy access. PoS will centralize to majority stake holders. I would bet that such energy access or stake follows a power law distribution. So long as that is true, neither system will ever provide decentralization.

Messaging queues are a core part of a lot of high scale distributed systems (source - Twitter) You want enough queue space to handle the expected volume and then some. Assuming you have that, you don't need to instantly scale instances out to match the amount of messages, you just need to catch up before the queue space runs out.
