There are some inaccuracies and misleading information here:

- Encryption keys are derived from various inputs including the user credentials, not stored in the TEE. The TEE is involved in key derivation and is really supposed to use a hardware-bound key not directly accessible to software including itself but it's an implementation detail that varies by device.

- Pixel phones ship with file-based encryption. It's not an option. A phone either uses FDE or FBE. If it uses FBE, then it supports Direct Boot (partial functionally before the user credentials for encryption are enabled via device-encrypted storage class) and per-profile encryption keys. It enables a bunch of possible improvements like authenticated encryption down the road, but isn't much of a security improvement itself. Nexus 5X and 6P only offered a partial implementation as preview for developers tucked away in the hidden developer options, not a user-facing option.

- Credential-based encryption is enabled by default when setting a lockscreen method.

- Android has a Keystore, that's not exclusive to iOS.

- Android doesn't use ECB even though it's implied that only iOS uses unique keys per block. Android does too.

There's some more, but I don't have time to go through and nitpick. It's clearly written based on interpreting other people's blog posts, etc. rather than direct knowledge of how it works or even reading the documentation. It doesn't even sound like they have experience using an Android device based on some statements they make.

The post totally misses out on things like key derivation and which data is kept at rest. The article misses the real remaining iOS encryption advantages (FBE data classes that Android hasn't added yet and more of the key derivation work is hardware-bound) and just tries to make it sound good by stating things that are not unique to iOS.
But the guy wasn't trying to market it, he was trying to investigate something. For his purposes it seems to have worked and been viable.

It's just that his purposes weren't commercial in nature, they were scientific.

Is there any actual data source on this, or is it just a narrative you prefer?
I love being barefoot, but I don't go barefoot in public because of sharps! I don't typically encounter broken glass or used needles, but both of those things will cut right through your "thicker and tough" skin before you can feel it.

Broken glass is far more common in modern times than it was on the savanna, so it's wise to dress accordingly. You don't have to wear Dr Martens, but a millimeter or two of Vibram can dramatically improve your quality of life.

My former CEO had some issues with Dyslexia and focus. He had major issues reading/spelling, and honestly all the employees noticed it.

Also he would kind of zone out a good amount while someone was talking about something and get caught repeating something or asking someone to repeat something.

But he was a very good person and always showed a strong interest in each employees' well being. We all respected him a lot and trusted him with the company. He really came across as a genuine person and we all just looked past the Dyslexia/attention issues.
The guy was doing scientific experimentation, having a go to market strategy wasn't involved at all.

That's not python specific. When you're running BFS, after visiting a node, you next visit each of that node's children.

From a python-specific viewpoint, dequeue.extend appends a given list to the end of the queue. The first example will raise an exception, but the other two are perfectly valid, and their behavior isn't special to python - it's just asking whether you'll want to vi it this same node again, or the node's children.

Incidentally, it's not as if there's any standard library 'node' class with a children method. This was a structure they defined, but did not share the definition of.

> I wouldn't allow barefoot in the office, just because of lawsuits if someone steps on something like a tack.

As someone who walked barefoot in Chicago for much of a summer: why is this everyone's nightmare legal scenario? Sure, I could be barefoot and step on a tack, but why is that so much more of a nightmare than if I'm not looking and put my hand down on a tack on a desk? (Well, maybe because I put my hand down with less weight than my foot, but that's not the point.) There are plenty of ways to be injured in the workplace, and we are allowed to manage most of these risks ourselves; why is shoelessness so particularly terrifying?

(Incidentally, one of my favourite objections to my shoelessness was someone who claimed that it was unclean (for others, not for me). I wash my feet every day, but almost never my shoes, so which one of those results in more uncleanliness for the places that I walk through?)
Local stores (Active Electronics, Canada Computers) have comparable prices to online and often even beat Newegg prices - even without shipping. And even when they're a bit more, I'll pay an extra $20 to have that graphics card today and know I can return it if it's DoA without a hassle.

Of course there are exceptions and extreme price differences where it's worth it to go online, but if it's within 10% or 15%, or sufficiently cheap in general, I'll probably take a store. Shipping often involves going out of my way to pick something up because no one is at my house during the day and even the local post service decides to drop things off in the next town over. Often I have to wait an extra day just for it to show up there and go through a huge hassle to pick something up.

Of course with more obscure stuff or a large price difference, you'll choose online, but in my experience that's surprisingly rare - I shop everything major I buy around and with smaller stuff it just makes more sense to go local. I order IEMs and some electronic components, things I can predict needing in advance direct from China for price and that's about it. I've never placed an amazon order in my life, their prices and selection just aren't competitive in my experience - but I suspect mostly that's because Amazon Canada is a lot worse than Amazon US.
Funny thing is; that's true! I always park my car there because it's empty and I don't mind walking.
I dunno, Philip K. Dick, Stanislaw Lem, Ursula LeGuin and Harlan Ellison were certainly on par with Delaney in the soft/mind-bending category. In my opinion, they have aged better; much of the more overtly experimental sci-fi of the late 1960s and early 1970s feels a bit dated today. J. G. Ballard comes to mind (his non-sci-fi novels are much better).

On the other hand, there is some brilliant stuff (like R. A. Lafferty, and William Borroughs's sci-fi stuff) that is undeservedly forgotten.

Quick question. How is the issue of human waste processing done in large scale temporary human accommodations such as a military forward operations base or a large scale construction township?

Would it have the necessary sewage handling/treatment facilities built first or are there temporary systems that can handle a sudden surge in the generation of human waste away from any pre-existing sewage treatment facilities?

Neither of those are the correct answer, though.

The correct answer is node.children, which isn't syntax-specific, it's about the pseudocode of whether you want to visit the node, or the node's children.

"Soon, of course, we’ll be doing nothing at all. Faced with the fact that we are losing American spaceflight altogether, suddenly the workhorse shuttle seems as beautiful and daring as the Saturn V did in the sixties."

Hard to believe this was written in 2015, while SpaceX was busy sending dragons to ISS and learning how to land Falcon 9s.

Edit: the excerpt is from Leaving Orbit, published in May 2015, but written in 2009, prior to the last Shuttle flight in 2011, which explains the sense of sadness and loss.

The rock crusher industry is ready to sell you all the machinery for making sand from larger rocks.[1] Cone crushers break the rocks down, and screens and cyclones sort the result by size. The best sand seems to come from "rock to rock crushing", where most of the cracking forces are applied by other rock. There are big crushers, small crushers, and mobile crushers. There's a whole category on Alibaba for sand-making machines.[2] While this seems to be a problem in India, the rest of the developed world is busily crushing big rocks into little ones.

There are aspects of motherhood that are very demanding and risky for women and in this regard I agree that there is still a lot of room for improvement and work to do to ensure women are protected.

However, not all men take the a passive role when it comes to parenthood and contributing in house tasks. In my family, we split effort and expenses evenly, but unfortunately this is not the case for everyone.

I think employers and society at a large should be supportive of women when it comes to motherhood, but other than that, it becomes very culture specific.
This is the point that really shocked me! I'd love to read more on this.
As someone with ADHD, you are really romanticizing ADHD. It's not a benefit.
Using pseudocode is a great idea. We've talked about that. We've not done it because we still need to decide what style of syntax to use (and that will still preference certain programmers). But maybe we should think about it again!
Apple doesn't do this in every country, but I assume it's an attempt by both companies to prevent a type of arbitrage.
I'd argue that iPad Pro isn't really competition for the Surface Pro. It's a tablet; the Surface Pro is a full-fledged PC. I would absolutely buy one because I love the weight and form factor, but I'd need at least 16GB of RAM, and I just won't pay an $1100 idiot tax for the top of the line model. I'll watch to see what iFixIt says about soldered RAM etc., but I'm not hopeful.
Yeah I live in a regional capitol in Japan (pop around 300-400,000 or so?) in a "dying" prefecture (population is going down), and in the past few years, one mall has expanded, another large one has gone up, and there's another new one planned. On weekends they're packed, and it can be impossible to find parking.

In very broad terms, PCA can be thought of as a pre-processing step to reduce the original data set to the "components" which account for the most variation in the data.

Essentially it's distilling your data down to what is most relevant, and thus helps say a classification algorithm work better by only training on the reduced "more manageable" data.

I agree, I have had a SP3 and SP4 with the i5/256 configuration, and I'd pay more for the 16GB option...but the i7 is too expensive of a leap. I really wish they'd offer an i5/256GB/16GB RAM option. The Pro 4 is a sizable leap from the 3 (surprisingly, mostly because the 3 throttles at high temps, I think.) So an upgrade with just 8GB will probably suffice...but yeah, it would be nice.
It is likely that they are mnemonic devices that encode information. Read The Memory Code by Lynne Kelly for more information. It's one of the most interesting books I've read, right up there with The Art of Memory by Frances Yates.

This is a common trope in the ADHD community. Namely ADHD makes us more creative.

I'm for positive thinking, but I heard about a study that claimed skills like creativity do _not_ go down once you are being treated for your disabilities. I do not know the details of the study, though.

Unfortunately this trope has meant that I've met many ADHD people who refuse to do medical treatment because they don't want to lose their gifts.

My theory has been that people with ADHD tend to end up having lives with rough social interaction, and you end up living a childhood more prone to "creative" endeavors like reading books or other activities you can do alone.

But for those of us with this disorder, getting proper treatment can get rid of a major social barrier almost entirely. I'd recommend at least trying medical treatment and evaluating the effects you feel.

Also, many pre-paid cards require the user to identify themselves before the card is activated
The book "Chaos Monkeys"[1], while irritating in many ways, has a detailed description of how Facebook correlates its own advertising data with information from data brokers (such as credit card transaction aggregators). This kind of stuff has been happening for quite some time. (As an extra bonus, the book describes how the author's ad-tech startup got into YC and was bought by Twitter.)

As an attorney who has struggled with dyslexia and ADHD my entire life, I can attest to the frustrations associated with responding to emails. While most people are able to quickly, if not subconsciously, craft a well thought out response, I spend countless minutes if not hours, fighting to find a way to transfer the sentence I have in my mind on to the screen. For those who do not have dyslexia, the best way I can think of to describe this limitation is the feeling you have when you are trying to remember a word, name, or sentence that is "on the tip of your tongue." It is frustrating and often becomes overwhelming.

I think everyone remembers the first ad to follow them around multiple websites. For me it was an ASPCA campaign.

The next version of that experience will be researching a purchase and where to get it, then seeing ads on the way that are customized to (a) the product you're buying and (b) your preferences.

If you're 55 you'll get michael jordan advising you to buy nikes. If you're 35 it will be Noel Gallagher (air noels?), and if you're 10 it will be the ninja turtles.

The good news is at a certain point the competition for eyeballs will become so fierce that the ads become honest & informative.

I don't fault Microsoft for doing this, the USB-C connector is so far from being off the ground in the market, there's no reason to support it on major devices yet. Most new technologies are going wireless, you move data wirelessly, you charge wirelessly. The need for USB connectors is dying, the old USB connector is nice to have on the Surface out of sheer convenience with some legacy devices, but I only use it maybe 2 times a year.
That last sentence is money.

For the first time I heard a car company CEO actually get that Tesla is different. The CEO of Toyota made a comment that what Tesla builds is more akin to the iPhone than a car.

And he's right. Tesla builds a computer that happens to use a very large battery, weighs about 4,000 lbs, and has wheels.

Nobody else in the business gets this. They think Tesla is just a car company with an electric motor, while completely ignoring the speed at which Tesla is able to roll out improvements.

I've said for a while that until the car companies start thinking like a software company, they'll be further and further behind. The difference is (quite literally) a company with a multi-year long effort to roll out a new version versus a company running the automotive equivalent of Scrum.

Okay, this is a small rant that is not directly aimed at you, so nothing personal. This is aimed generally more at people in the privacy at all costs camp and the like. If there's some viewpoint I'm missing here I'd also love to hear it, so it's not really a mean-spirited rant either.

Google owns the internet at this point. For general use purposes, they ARE the internet. So avoiding them should really have at least SOME effect before it's even seriously considered.

What does getting off Google do?

It doesn't hurt them, as there's no way a significant number of people will take action, at least in the near future.

So, then it must be done for you. By not being in these services and having all this data collected on you, what do you actually gain? Likely, nothing at all. You won't be able to be tracked down as easily if Google turns evil, sure. If their data is breached in a meaningful way, sure again. But, for both of these, emphasis on "as easily". At this point, if you're looking to maliciously track down just about anyone, it's not hard at all. You'd have to go fully off the grid to get this. And in that scenario, what do you gain again? We follow down the same road of "I only gain something in very unlikely scenarios" again.

So to me, the only way this type of perspective makes sense is if you believe those very unlikely scenarios (from my view) are much more likely. And if they are, we're all fucked already, and being one of the few to be off the grid probably won't matter in the end.

Basically, at this point, you've already given yourself to Google. Rather than decide whether or not to trust them, I think putting more effort into trying to influence them towards "not being evil", as they say, is much more of a realistic move for someone with concerns over data, privacy, power/security of all this, etc.

Am I missing something?

PS: I understand Facebook - for some, there are no significant benefits you give up. For most, you're going to give up a lot more with Google.
I understand that even in the USA, to detain someone for 24 hours you need something like a warrant or some kind of special permission from the judiciary. I mean, if it's got to the point where the border force (?) can just detain you on a whim, I have a much better way to keep my data safe: by not flying to the USA.
This sounds like some bullshit to me. Not that Google claims to be able to close the loop, but that a Google ad actually influenced me in any way, let alone a physical purchase in a brick-and-mortar.

PPC Ad-words perhaps influences me if I'm researching a product or service, but that's mostly a function of search results placement rather than . Usually I scan down below the first few search results because those are people trying to tell me they're what I'm looking for and they usually aren't.

I will readily admit that I have to consider that I am a freakish outlier, though.
