>“The on-device microphone was never intended to be a secret and should have been listed in the tech specs,” a Google spokesperson said. “That was an error on our part.”

I don't know, it sounds believable. Maybe they put it there "just in case", but didn't want to put it in the list of specifications because it had no software support, and having it there would've mislead customers who could've thought the microphone was functional software-wise.
> Why not optimize the function, and aim for only 256-bits of internal state (with 256-bits of entropy) ??

It's a lot more difficult to ensure that accumulators contain full-width entropy at all times.
The trade-off in this algorithm is that we intentionally use bigger accumulators and don't even try to maintain the entropy at full level all the time. All it needs is to ensure that the level of entropy is _at least_ 32 bits per accumulator, which is much easier. This leads to better speed.
I'd be interested to hear more about this, do you have any articles handy which go into detail of the specific language of this agreement? I'm sure this may be a possibility, but I'm skeptical, I'd be more inclined to believe YouTube's lawyers would be more than smart enough to advise them not to break that kind of contract. I'd love to see the language though if you have it handy.

Giving up the power to pick and choose what sort of content would be allowed on their platform seems like something no sane organization would give away. That would be like hackernews signing an agreement where they wouldn't be allowed to moderate, highly unlikely.
Considering majority of people are employed it’s already a huge step forward. Can’t we at least get there first before we criticize them?
If someone's really motivated, there's also enough online courses which give certificates (MITx style) to collect almost the whole uni curriculum. Even with paying for that certificate, it's way cheaper than uni.
I don't see software freedom as a bad thing, I just disagree with the moralism of the free software philosophy. I don't believe there is an implicit moral dimension to software licensing, it's simply a matter of technical and financial tradeoffs.
Maybe we should have 'intuition checks'? A kind of test (not graded) that regularly checks that key intuitive concept have been learned? Like show a circle and ask to place the sin,cos..
That's not a representative example - those are extremely high profile pages (maybe the highest). Wiki pages for less-known polarizing figures are far below that standard.
Same thing in France. Filling taxes for employees is essentially just clicking a button.

But if you are self employed, you have to hire an accountant. It is not a legal obligation but there are so many things that can go wrong that you are putting your business at risk if you don't.
I am convinced uml was created to sell expensive tools for using uml. If I never have to see it again I will be happy.
In my view, school does not admit to a singular purpose, even if a number of people seem to achieve similar results from it. Instead, different students can pursue different strategies through school, and get different things out of it. Even if signaling is a benefit of school, it doesn't need to be the only benefit.

School is a complex system. Take it apart. Figure out how it works. Adapt the pieces to make it do something useful for you. In short, hack school. It shocks me that a site devoted to "Hacker" news hasn't guessed that school is begging to be hacked, and makes me wonder how many true hackers there actually are.

Of course one possible hack is to follow a path of least resistance and emerge after 4 years with nothing but "signaling." But it's not the only hack. Signaling in the absence of real education could be viewed as a pitfall of school, not its purpose. A dark pattern, if you will.

In another age, this message would have been expressed by elders to their children in some sort of patronizing way, such as: "What you get out of college depends on what you put into it." I've certainly told this to my kids, along with the somewhat more detailed explanation about hacking.

The coding interview is a clue. At its core is a question: "How did you hack school to your advantage?"

Can school be hack-proofed? Experience with complex systems suggests this might not be a good idea, as it can kill the good hacks along with the bad, or make even worse hacks emerge.
And the vast majority of times I've seen attempts at that, it ends up being some combination of distracting, condescending, and irrelevant to what I was trying to do.

I'm sure it can be done well, it just isn't.

If your Android phone is compatible[0], you might enjoy the result from installing LineageOS on it. If you wish, you can continue to use the Google Play Services package (which is where Google does all the tracking, and is also the only way to get the Play Store). I chose not to and use F-Droid and directly downloaded APKs, which saves me from running any proprietary code that I haven’t vetted carefully.

It also solves the planned obsolescence issue, because my Galaxy S4 is screaming-fast on a version of Android from three years after its last manufacturer update.

I’ve never driven a single-seater, but to some degree it’s intuition, and to another it’s just getting to know the limits through practice. I think Gasly spinning in FP2 while trying to find the limit is an example of that. You’ll be familiar with the twitching feeling when traction starts to give.

I don’t know if they have any on-board telemetry to measure this.
Their incentives with regards to data are aligned differently - Apple make most of their revenue from selling hardware to their users, Google make most of their revenue from selling ads to someone different from their users.
> The essential question is "why do we think that every skilled job requires a four-year college degree?".

That’s not accurate. Law school requires any degree followed by three years of a law degree. Now that’s pure signalling. Every other Anglophone country bar Canada has undergraduate law degrees instead of requiring what amount to two undergraduate degrees.

Maybe I've worked with bad code for too long, but my opinion is, being the one person who understands some clusterfuck of poorly designed and hard to read code is job security and improving it can be satisfying. Reducing coupling, making a codebase more readable, rewriting code to make it more unit testable, or making a given piece of code run faster I find to be satisfying and educational. You learn from direct experience a myriad of ways in which not to do things and exactly why not to do them, and you can use this information going forward when you write your next feature.
The #1 reason not to use Apple is their arrogance toward their users. I don't want them to lie to me about my battery, nor make me choose their music over spotify and engage in other customer-hostile policies to make money.

If it were only that simple, sigh. Google is much worse. Apple at least lip sync's privacy, I suspect when it is to their advantage.

I believe Apple just has no clue as to how to create products any more. How much money are they sitting on and and this is the best they can do?
Sadly enough.

TFA states:

> On the contrary, they showed politically diverse editor teams on Wikipedia put out better entries—articles with higher accuracy or completeness—than uniformly liberal or conservative or moderate teams.

The problem is that many of Wikipedia's editor teams are not politically diverse. And some, based on my limited experience, seem totally nonfunctional and dominated by trolls.

Maybe polarization does generate high-quality articles about popular topics. But for topics that aren't so broadly polular, toxicity and edit wars seem more likely.
I am 57, I still enjoy coding but struggle to work in teams. That is probably more my nature though. My experience as an older developer is that people are openly bigoted about age, that they would never be so open about race, religion or gender.
Is there anything about this on the internet that supports this thesis? Any studies?
I’m seriously kind of tired of this argument.

We’ve gone from “not choosing is a choice” to “every choice is political”.

I’m sorry but the latter doesn’t immediatly follow from the first.

You can and are totally free to not use a technology or buy from a particular company for political reasons, but that does not mean that others are making a political choice when doing so.

Similarly you should argue that eating meat is a religious choice, since some religions prohibit meat consumption.

I find this kind of reasoning bogus at best.
Thanks for this, I need to reconsider Auckland then as a final destination as the companies there in general look much more interesting than in Wellington.
The general argument is that iOS is more secure because Apple strictly controls both the hardware and the software. The two are very tightly integrated in Apple products, which means proprietary software for e.g. segregating userland or interacting with the secure enclave is specialized and well-audited.

The other (perhaps more compelling) argument is that Apple is only able to invest this level of security in its products because of its spectacular profits, which would likely be much lower if iOS were open source.

That's basically the gist of it.

EDIT: To whoeever downvoted this, I'm just relaying the argument.
> While collecting data on users is nearly inevitable in today’s corporate world, secret, undisclosed, or unpredictable data collection—or data collection abilities—is another problem.

A smart-home speaker shouldn’t be secretly hiding a video camera. A secure messaging platform shouldn’t have a government-operated backdoor. And a home security hub that controls an alarm, keypad, and motion detector shouldn’t include a clandestine microphone feature—especially one that was never announced to customers.

This sounds too much like trying to move the overton window for me. If the next generation of smart devices is advertised as "no hidden cameras and microphones! (we'll just spy on you with the visible cameras and microphones)", I don't think this would be a win.
Stallman doesn’t propose not paying for the toilet.
Recent examples of why not to use apple:

1. Their new keyboards are terrible, and are buggy.
2. Lack of headphone jack on phones.
3. Vast price increases for relatively little new features.
4. Constant upgrading of the OS which breaks half of the software you use.

PUBG and Fortnite are the most popular competitive games ever? and randomness is paramount in both.
So what are we suppose to do other than flagging for utter nonsense like this one?

I can give you a pass what whatever ideological view in Stallman's own little world. But things like

>Apple pioneered techniques for avoiding the US corporate tax (even though it is far too low) in order to pay next to no tax.

Apple is the largest Tax payer in the US by far. Given how other company dodge tax I sometimes wish ( as an Apple Shareholder ) Apple did that too, but they didn't. Apple Pay every single bit of Tax, and until the money are being bought back to US they don't have to pay profits earn offshore. You can argue about whether Apple should pay tax in EU. But that is a completely different Topic.

>Apple turns a blind eye to environment in China.

>Worker abuse

Apple didn't build Sweatshop. Plain and Simple. And neither did Foxconn. No one was forced to work Overtime. People wanted to do it because they make Money. And for people coming out from village in China, getting into Foxconn was the first step into City. And if you are wondering why there are people suicide, there were no more than a 100 people over the years in total out of a peak of 2 Million employees by Foxconn.

And then you thought he was against Apple, and you start looking at all the other parts like Amazon. And the first line:

>Amazon has so much power over the US retail economy that it imposes its power over all participants.

I would have expected anybody doing any sort of programming to be half decent with logic. And since anyone doing programming would have know how to use a computer, and doing a little Google Search on Government Official Data, he would have known Amazon, despite being a household name is actually not quite a dominant player in the whole US retail revenue segment.

And countless other examples, bashing for the purpose of bashing.

A less dense book for commutative algebra is Miles Reid's Undergraduate Commutative Algebra, but it doesn't cover tensor product of modules which will definitely be needed for algebraic geometry.

There was an entire controversy about how hard Apple made it for law enforcement to access iPhones, which indicates security benefits.

Apple’s business model also aligns with user privacy (so far).

It’s also worth considering Apple’s CEO personally values privacy because he had to keep his sexuality a secret his entire life until he reached such a prominent position he felt safe to speak out.

I agree that the strongest evidence is the source code, compiler code, and electronics schematics. However, there are other forms of evidence.

India is already firmly in the Western sphere of influence, and I still don't see how America "lost" any bet. A strong India is absolutely in our favor given it's a democracy with fundamental rights and rule of law.

The example you cite is not surprising to me in the least. It's realpolitik, and every regional power does this and always has. That book was self important wish-fulfillment on the part of the author, IMHO.
Even more ridiculous is that you can do any corrections online. So you can pretty much send the Canadian tax agency any gibberish and then fill in any claims or deductions online later after they have fixed it. You just can't initially fill in anything so as to protect the business of the commercial tax preparation agencies.
It's on their list, and at the rate that they are moving, it will be there soon. It is based on Mono, so there shouldn't be too much friction there. Unity is good, but for Android and iOS I play with Raylib in C.

I personally prefer SIM-free Android One smartphones[1], which come without any bloatware and with monthly security updates.

Not only they offer the best price / performance ratio, but they are also easy to keep private by uninstalling / disabling those few apps that come with the device.

Caplan's been beating this drum for years. Pretty telling that he doesn't touch on engineering or any real disciplines in his article. It's possible for someone extremely self-motivated to teach themselves some of those subjects, but you won't learn them by sitting through lectures.
Let’s not water down the major issues with a long list of grievances. Apple’s anticompetitive practices are hugely problematic, and it’s the one area in which Apple refuses to budge. That’s where we need to focus, starting with the App Store.
Apple does neither of these things.

> The whole point of the article is there is zero correlation between people who've graduated from college and people who haven't in term of how well they do on the job.

... among the population who have been hired to do the job. This is conditioning on the collider. The people without a degree who got in are a highly selected sample compared to all people without degrees. Anyone who used this to argue that a degree wasn’t a strong useful signal Wouk be making the same mistake as those trying to get rid of the GRE in graduate admissions because in the population admitted the GRE doesn’t predict anything. If it did that would show under or overweighting ofbthe signal it sends. Zero correlation shows it has been given appropriate weight.

> 1. Do they limit the freedom of the developer to keep source code private?

There's a clash between user's and developer's freedoms: if a developer is free to keep the source code private, then said software's users are not free to study, change it, and distribute those changes.

The free software movement prioritizes user's freedoms (the 4 essential freedoms [1]) over developer's freedoms. You seem to do the opposite.

> 2. Do they make it harder to sustain a living wage through the labor of writing software?

Your wording makes it hard to answer the question. If you get paid purely to write software, it doesn't matter if said software is free software or not. If you sell software copies/licenses to pay for your development, then it is objectively harder to earn as much.

I could not care less with Apple abiding by national laws of each country (to provide or not provide some app). Wanna do business somewhere, play by their laws, not impose your clout (which for some companies is bigger than some states, hence the "Banana Republic" notion) to have the laws of your preference enforced. (Most Americans are OK with it, because it's usually their companies doing the enforcing. But consider the opposite, you being forced to accept the terms of some other country).

But I dislike their enforced prudery. Unless something is considered illegal (e.g. CP), it should be up to the users to decide. At worse, implement age restrictions when shopping.
So by this standard, is there a computer that I should use, or is all computing in 2019 unethical?

I see he's using a >10yr old Intel CPU, presumably to avoid the Management Engine, so presumably he thinks it's OK to pay money to these companies in certain circumstances?
Growing up in Indiana, we had unique "Waffle House" restaurants. These were a local chain that was more like a Dennys than the Southern Waffle House. I don't know if the Indiana Waffle House was started as a rip off of the other Waffle House or just a coincidence. For years the Southern Waffle House was known as "Waffle Steak" in Indiana but they have changed to the real name and the Indiana Waffle Houses have either closed or changed their name to Sunshine Cafe. https://en.m.wikipedia.org/wiki/Waffle_House#Waffle_and_Stea...

“Unexpectedly smart” and “hidden, software enable-able features” are both anti-features of security hardware.

I don’t think Google deserves the benefit of the doubt anymore: these untruths happen with every product, and they’re always in Google’s favor. There’s a consistent pattern of Google specifications, documentation, etc being knowingly untrue.

The only “error” is Google got caught deceiving people, again.
LineageOS is pretty nice, but it's a bandaid and they dropped a huge amount of older devices from support when they left the CM brand. Hopefully postmarketOS will become more usable in the future, and we'll be able to use that on existing hardware, perhaps in combination with something like Halium when needed to make the proprietary driver blobs usable with a custom, non-AOSP userspace.
It's interesting you bring Plan 9 up, because it was closed source for a long time, who knows if it was long enough to kill interest. Probably another factor for success.

> Would you go to a doctor that learned medicine form YouTube?

Depends on my ailment. Most of the time people go to the doctor they are told to get some rest and maybe prescribed something. I don't think that needs 8 years of medical school. And doctor's don't even necessarily do a good job at prescriptions either, since they tend to over-prescribe in the US
