While parents whining about homework isn't new, what is new is research beginning to pile up that homework doesn't help below a certain age.

I am, quite rightly I think, skeptical about most educational "research" (remember "new math"--aka set theory?). However, educational research has gotten much better. And there are starting to be consensus answers that conventional psychological research seems to bear out that educational systems simply ignore.

What worked to create human inputs to an assembly line may be quite suboptimal for creating humans capable of functioning in a knowledge-based economy.
Why would IBM set a hard limit on that, though? Assuming defects are normally distributed, it would make more sense to say: mean of X per N defective parts, with a variance of Y with a P-value of Z.

Though who am I kidding, no one probably evaluates production like that. Though I imagine chip makers are pretty serious about that kind of stuff.
You've missed the fact that the OP said ALL.

Apple does business in China the way they have to do business in China. I don't agree with that, but I'm also quite sure they have not given my iCloud keys to China.

Depends on the "workstation like PCs" and "commercial compilers/IDEs".

Anytime I put together a decent PC with best of breed parts, it goes to 3-4K. And commercial offerings from Dell with similar specs also go there, same for laptops, e.g. Lenovo, and the like.

And I've seen commercial compilers/IDEs priced in the $1K/$2K range, with which you can surely buy a Macbook Air or similar...

Nobody would willingly run outdated, vulnerable software if there was an easy, direct, and supported way to root your phone. Sell phones locked for security or whatever, I couldn't care less, but give people the option to root when they want.

So many iPhone users knowingly refuse to upgrade to newer versions of the operating system just so they can keep their jailbreak.
Wow. In one short week this all happened and was defused by the teacher:

> There is no such thing as a national youth movement called the Third Wave. You have been used. Manipulated. Shoved by your own desires into the place you now find yourself. You are no better or worse than the German Nazis we have been studying

And

> Silence is what happens when you feel shame

What I find particularly interesting is that the basic elements of what happened can be seen in all walks of life, even in tech. Eg. The 'gamification' that many products use, is very much like the 'follow our rules and you'll be rewarded', and the 'belief' in a central tenant becomes a central rule of authority. The marketing slogans used to gain groundswell are the same: an agenda to deepen one's commitment to the cause.

Even HN, with it's karma, @dang as our bodyguard, with YC as the central body. All down and up votes on this comment will prove the point that the secret police are here too, gauging my suitability to the cause.

So, a fantastic article that shows we all have natural tendencies to be sheep, but are all also wanting to be elitist sheep.

The precautions a cautious user will want to take when armed with this information don’t really change or become more burdensome whether there’s one group of attackers or many, so I don’t see how that changes the calculus at all.

It’s also probably not a terribly great assumption that no one else has independently discovered this vulnerability that’s already been independently discovered twice. Caution suggests we should assume this is in the wild and act accordingly.
Perhaps I just don't want to fucking be bothered with a gender label and will use the perfectly acceptable gender-neutral pronoun. God tells me that this is a reasonable thing to do.

Somebody recently referred me to this nonsense: https://www.mypronouns.org/how

It's funny that this pronoun debate in the US is so anglocentric, too. Just shows the level of critical thinking these agenda pushers really have. Why? Why is it only the 3rd person pronouns that are special. Why are 1st and 2nd person "as-is"?

I've not seen that criticism myself. But to me what Project Zero is doing re: Apple vulnerabilities is great. I own Apple products and it's only going to improve/harden them

However, I do think some of the motive is to take a bit of shine off Apple - meaning it's partly a marketing campaign.

As a licensed quantum computologist (um... not really, but I do work for a major QC effort)... your skepticism is not misplaced.

I can only speak for my place of work (not publicly) and pass along scuttlebutt... but, my understanding is that it's largely the same everywhere. Some efforts have tight budgets, some have billions backing them; but QC research is hugely expensive with more unknowns than knowns. People giving out the cash want results sooner than later. At my workplace, the researchers are in a continual pitched battle with management to keep a rein on marketing, limit expectations, etc., and it's a major distraction. When management misunderstands an early result, and oversells it to their superiors (if not the press!), suddenly they think it's appropriate to make "Quantum Supremacy" a task with a 6-month deadline.

It all makes me want to crawl into a box and take a nap.
In colouristics there are several methods for constructing a color palette (color gamma) based on the arrangement of colors relative to each other in the color circle and, usually, having the same brightness. Harmonious perception of which is not sufficiently substantiated from the physical point of view.
The wave method of building color palette based on the relationship of color and acoustic waves, and also the concept of consonance (harmony) in music theory. More detailed description of the method is here - https://wavepalette.com/about/

A few days ago, the algorithm was completely finalized and posted on the site - https://wavepalette.com/. There is also a mobile application and ready-made palettes - https://wavepalette.com/palettes/
Yeah, I didn't elaborate this enough (because it wasn't really the main point). When I said "similar" I meant "things holding onto things they should no longer be holding onto", not circular referencing in particular.

I realize that the kind of bug that leads to effective memory leaks with GCs has its own equivalent in manual memory management, but my overall point was that neither manual memory management nor GCs make you immune to leaks from badly designed or incorrectly implemented data structures. Each takes some aspect(s) of pain away.

Thank you for sharing your experience. It may be useful for, say, those writing an introduction to the Gita for certain audiences.

Contrary to your impression, the Bhagavad Gita is not a “story”. Although the first chapter (of 18) does have some setting (owing to the place it occurs in the broader epic Mahabharata), when most people talk of the Gita they mean the content of the “chat” itself: what Krishna (“some Hindu god”) said to Arjuna (“a guy”). (Starting with Chapter 2, which is where many commentators began their commentary.)

Also, the Gita is in a sense a concise summary of various ideas, also more extensively covered in the Upanishads and elsewhere. As one of the verses often recited before it says “sarvopaniṣado gāvo dogdhā gopālanandanaḥ / pārtho vatsaḥ sudhirbhoktā dugdhaṁ gītāmṛtaṁ mahat” — the analogy is that if you think of all the Upanishads as cows, then the cowherd Krishna to the calf Arjuna gave divine milk by extracting the Gita from them. It is not someone's thesis or argument — Krishna just reminded Arjuna of what he needed to be reminded of (and by extension, what most of us need to be reminded of). So it would make sense that to someone who's already familiar with the ideas, seeing them in one place in the Gita would have a different effect than to someone encountering them for the first time, and (apparently) without context.
I haven't benchmarked it.
Yup. I drive a lot and don't care much about performance as long as I can get up to highway speed on the on-ramp. Fuel economy, maintenance, longevity all matter a great deal.

I protest, totally protest. Under no circumstances let people with dotcom webdev mentality run anything really serious in aeronautics.

I myself had a rather similar talk to what that the panelist had with Kitty Hawk people with a very well moneyed, but also very naive CEO of a drone delivery startup. Some sarcasm added, but it went along these lines:

Me: your best bet is to make a helicopter. Men much brighter than you were banging their heads against the wall non-stop for 60 years trying to solve this exact problem.

Startup CEO: But I hired most brilliant engineers from Amazon and Waymo for that. I'm paying them near 200k each.

Me: If this, this, and this thing breaks, your drone drops dead upon an urban area. And if you get into negative gees over ridgelines, your motor don't have enough torque to keep COM behind the centre of aerodynamic forces to prevent inversion. You can't change the law of gravity.

And he was like "can't we really do anything about that, can't we?" These people are so used to the culture of "easy solutions" that it's scary.

I don't get why you're being downvoted, because that's an excellent question: I do that all the time: I'm using F-Droid more often than the Play Store. Actually, I haven't ever used the Play Store on my second smartphone (it requires a Google Account and I don't want to link it to a Google identity) — I've tens of apps on it.
That stems from the doctrine that leadership skills are industry independent. Unfortunately in reality every industry has a couple of big strategic issues that can't/aren't measured with a dollar value and the standard MBA business outlook ignores them in favour of measurable things.

The downside of this is sometimes management attempts to optimise out the company's comparative advantages. Sometimes on purposes.
One way to handle these kinds of contentious moderator debates is with freedom. Since Stackoverflow/Stackexchange does not open source their code, there are a number of Free Software clones which handle questions and answers Stackexchange style.

I will link to just one: https://github.com/ASKBOT/askbot-devel

Point being, there is nothing stopping someone from hosting this code and making their own Q&A board with their own moderation policies.
Kudos to Epic for using their power to attempt to break Google's Play Store hegemony, facepalms for unfortunately proving one of Google's (both legit and pretended) concerns on safety and security regarding acquiring apps from outside of the Play Store.

Unsold stock could still be more profitable if the bids fall right, although could of course be noticed depending on the product and audience.

This all sounds nice but it ignores the issue of liquidity... You can't afford to exercise your options because you can't sell them. The secondary market sounds nice in principle but I never had success with it. And if you can afford to buy them you have to budget for the tax bill that will hit you with the AMT truck. The move to the 10 year option exercise period helps though so you should only consider companies that offer that. 30 days, 1 year.. not long enough.. 10 years might be enough.. For example, Palantir has been in business for 16 years with no IPO in the near future. So the "deal" here, or the implicit bargain isn't great.

That is true but SE gained a critical mass of answers by encouraging one set of behaviours through its points and badges system, then pulled a bait-and-switch and told those subject matter experts that they were no longer welcome. Wrong demographic, see.

SE is dying. The quality of the questions is falling because being welcoming to new users is deemed more important now than the newcomers absorbing the culture. Questions go unanswered. The real technical Q&A is on Github now. But this is what Spolsky and Atwood wanted all along, good luck to them with their new community of newbies and SJWs.
A Tesla Model 3 usually sells for something like $50,000, I'd guess - it's not competing with a Honda Accord. This article is a year old so it's outdated, but it suggests an average sale price of $60,000 for the Model 3. This clearly puts it in the luxury/performance price bracket.

https://cleantechnica.com/2018/08/23/tesla-model-3-average-s...

Apart from that, the EA888 engine I mentioned is used in the VW Golf, the 7th best selling car in the world.

https://www.best-selling-cars.com/global/2018-full-year-inte...

The engine is considered highly fuel efficient, rated well above 30mpg for most variants and many people report >40mpg in real world usage (obviously this data will be biased towards higher numbers).

The emissions, however, are supposedly great but I don't trust VW at all on this front so I'll just assume they're doing something shady. They are being legally sold in California though, which is really the highest emissions bar there is, so I'm not sure what you'd expect from them (again, assuming they aren't doing shady shit).

And unusually for VW, this is considered a reliable engine. It's been around and iterated upon for much longer than any Tesla.

There is no apples-to-apples comparison between electric and gasoline vehicles, but claiming one of the most highly awarded engines in recent history is lacking in performance is like claiming Teslas are worthless in cold climates - it's more rumor than fact.
Disclaimer: I know this because I tried very hard to justify living in Europe for a few years.

It is true for salaried professionals. Salaries are about 30-40% higher in the states. Taxes (which cover education up to uni), health insurance, and 401K account for roughly 30% of our gross salaries, leaving us with more left over than our European counterparts gross (we also work more hours, but not enough to make up the difference). Of course, if you look at non-professional employees, it’s probably better to be European.
You forgot about ordering.

8 binary bits in order can encode 256 states, as if every bit was capable of encoding 32 states.
This reeks of theranos level obfuscation. It’s exactly the kind of investor-speak you use when trying to separate fools from their money.
Well then too bad, that is going too far.

When did it become a cultural imperative to explicitly call out someone's gender. This is not the same thing as misgendering someone. It's one thing to say "he" when someone wants "she." Doing so is antagonistic. But the English language has perfectly usable neutral pronouns - "they" and "them" -- which are serviceable whenever the gender of the parties in a discussion are immaterial -- which is the majority of communication on the Internet and out in the open. I will continue to use them, thank you very much. If you explicitly ask to use "she/her" or "xyz/pqr" or whatever the hell you made up, and I am not close enough to you to care or need to care about your "gender" then really, please grow up.. the world doesn't revolve around your agenda or your identity.
I've been a professional developer for about 5 years, and I've never seen great professional mentorship. In my experience, one should plan on working alone, and look & hope for good mentorship. For my first job, I was lucky to get a single offer, and that meant I didn't have much of a choice in what kind of learning & earning potential I had.

There is precedence for a fixed-wing rotor-based VTOL aircraft with the Osprey, at least aerodynamically. Operationally, the Osprey was a bit of a disaster.

I wish this post focused on the core issue: they don’t make enough money from Mac sales to be willing to replace a framework (Carbon) deprecated by Apple 15 years ago, and are instead terminating Mac support.

I’m surprised they didn’t do that sooner, but blaming Apple for ending Carbon support is beside the point of “not enough revenue”.

Either of your mentioned options for implementing template parsing were used by implementations when C++ was conceived (but before it became an ISO standard). Your "token string" approach is the route that Microsoft took with MSVC, whereas other compilers went with what later became standardized as "two phase lookup".

In short: Token stream alone is not enough. You need to decide whether T::A * b; is a pointer declaration or a multiplication immediately when you parse the template. If A is a dependent name (i.e. if T is a template parameter), it is assumed to be a variable (if that's not correct, the programmer must use typename or template).

MSVC has only recently completed their implementation of two-phase lookup, some twenty years after it was defined as the correct option in the ISO C++ standard. They have an excellent writeup here: https://devblogs.microsoft.com/cppblog/two-phase-name-lookup...

>extremely inconvenient.

Maybe. I'd argue "extremely".

It does suck, for instance, that Discord as a Flatpak can only access a fixed subset of $HOME directories. But it can't scan your machine's processes like ordinary Discord can (to report the game you're playing), which is a privacy gain. The security (and portability) advantages of sandboxing/containerizing apps may outweigh the hassle of the workarounds/memory inefficiency.

Math + Philosophy I think is a great combo. My study of philosophy in college opened my eyes like nothing else I’ve ever learned since besides Daoism (though that might count as philosophy as well, I guess).
The good side of community, order and obedience to authority are the entire civilized world and all the goodies within it. Hospitals, electricity, cozy homes that stay cold in the summer and hot in the winter. Without the human tendency to group up and follow leaders nothing works and little gets done. Sometimes this habit goes wrong on us, and results in lynch mobs or Nazism. But overall it's still one of our greatest strengths as a species, and we need to be aware of its failure modes rather than rejecting the whole idea outright. Cooperation is one of the animal world's superpowers.
True, but it isn't just to sue someone else just because they do have liability insurance.
