It’s one thing to say someone cuts corners but in the world of electric vehicles you really can cut corners.

For example, have no precharge system. Don’t monitor the temperature of every battery cell. No manual disconnect for the high voltage battery. Put cab heater on the same coolant circuit as the engine so that if you use the heater the drivetrain efficiency plummets (but not on paper). Use an electric vacuum brake booster so you can leverage cheap components from petrol cars (although every single one I’ve seen has been prone to early failure). Skimp on your front brakes/calipers because you have regen. Completely ignore battery impact protection. Use non automotive components that are only rated to 60C because you can on an EV and not necessarily because you should. Select cheap low voltage components with barely a safety factor on HV bus without considering that IGBTs derate approx. 50% during a solar event.

The US right against self-incrimination does not protect against being required to provide records which already exist.

It only protects against being required to give incriminating statements of a testimonial nature.

As an extremely contrived example, if you've spontaneously written a confession to a crime and the cops learn of this, they can subpoena you and order you to hand it over. But they can't just require you to write out a confession or speak one in court.

(Cops do get people to confess, of course, but there is some element of persuasion and choice involved in that decision.)

As a much more common example, with the right level of evidence to motivate this request they can require your fingerprints as part of a criminal investigation. This is true even if they do not arrest you and even if the fingerprints will incriminate you. But they can't require you to answer incriminating questions.
I mean, it might. I only had to construct one trie, and I used it hundreds of millions of times, so O(1) child (hash) lookup ended up being faster than the O(log(n)) binary search lookup, at best, from the data structure described in the article. And since the data structure in the article wastes some space as well, I may have even used a similar amount of storage.
You can implement most things with dynamically allocated vectors. Just use indices instead of pointers to link the elements. This can also bring advantage in space efficiency if you're able to do with 4 byte indices instead of 8 byte pointers.
At some point in the month those accounts make some kind of connection with Facebook’s auth system. Those accounts are almost certainly not 1:1 with people.

The real usage of Facebook is probably a fraction of that number. They have huge incentives to mislead about those figures.

A much better stat would be the number of individual people (eliminating known duplicates and businesses) who post an original post to their timeline each day, each week, and each month. Facebook don’t post those figures because they would be pretty darn low.

You can consider the entire virtual memory space to be a big vector, where a pointer is just an index into it!

Paying for Social Security using payroll taxes as we are currently doing seems like national suicidal, because younger families gain a greater share of their total income from working, rather than from holding land and investments.

Payroll taxes increase the effective tax burden on younger working families in their prime reproductive years, which means they can no longer afford to have the same number of kids, or to have kids as early. When younger workers are taxed, the less affordable it is to create new generations of younger workers, and fertility rates decrease.

The best thing the United States could do to address this would be to eliminate FICA \ self-employment taxes and fund social security out of a general income tax which taxed capital gains and dividends at the same rate as labor income. An even better solution would be fund it via a national real-estate property tax or national land value tax, and not to raise it from taxes on earnings at all, as Thomas Paine originally proposed in Agrarian Justice.

Language sidebar:

You might want to alter your word choice a bit. As an American, “must be convicted” reads as “must be found guilty in court”, which I’m pretty sure isn’t what you meant. Even changing the order to “brave, convicted and honest” would help — putting the ambiguous item in the middle of the list helps to clarify which meaning you intended.
Yes, that's how works the RB-tree example I linked. However, it is much harder doing that for implementing tries, except if you work only with the full node case, which would imply wasting a huge amount of space. At least, from my experience.
However that's a pretty poor vector. It's not homogeneous (you put things of different shapes inside). That also implies you need sophisticated memory management, leading to further overheads. You cannot meaningfully iterate it.

Client-side encryption doesn't always solve this.

Two main exceptions:

First, if the encryption is unlocked by a physical device that doesn't require a memorized code, or by your personal biometrics, they can get that without violating your right against self-incrimination.

Second, if they know what information is being hidden by the encryption and just need a copy of it to prove their case, the foregone conclusion doctrine lets them demand it anyway. (They are not demanding the key or password in this case, just a decrypted version of information they already know exists.)

But sure, in other cases it can have the effect you say.

> That depends on the functionality requirements of noSQL customers. I posit that writing a new, indepedent RDBMS that implements the latest SQL spec with the same maganement and replication capabilities as the incumbents is on-par with trying to compete with WebKit and Gecko. The SQL Server engineering team at Microsoft is about 1,000 people according to my friends on campus.

CockroachDB is the newest from-scratch SQL engine that I am aware of: https://www.cockroachlabs.com/

They re-use the RocksDB K/V store maintained by Facebook (in C++) as the storage layer, and their own code is written in Go, so I suspect that their development work is probably a lot less time-expensive than the teams working on older SQL databases.

Well deserved. We live in times of epic space dramas, but Cixin has some of Clarke’s imagination in his books. I also enjoy the cultural twist of reading into Chinese “normality” through his books. It could be interesting to see a book with less dark gloom alike to Clarke and Asimov’s earlier and more optimistic works.
I have the obsessive behaviour where I want to like devices (GPD Pocket, iPad, ...) which have usability issues because I really do like them otherwise. The iPad Pro is one of them; I love the device; I even do not mind the keyboard (although Apple could do so much better) but the software is annoying. Although I do 80% of my work on the iPad Pro by now, it has serious issues as described in the article and others. I like the chromebook way of working; it all is sandboxed until you unsandbox it. I would hope that Apple, with it’s chip designs, would be able to do more advanced sandboxing and allow more freedom.

Old movie spoilers ahead

I watched a short movie (an episode from the Outer Limits? It was ~20 years ago) about some army rangers who stumble upon, track and ultimately kill an alien.

When observing it closely afterwards, they realized it was an alien child sent to Earth on some kind of children camp.

The primitive livings on that planet killed the child. The parents were not happy, blew up the camp (and our planet).

So yes, I also favor the Dark Forest approach
For some it never comes, that's the problem. edit: apart from "being aware" being kinda unrelated to anything I wrote, since you can still be unaware or aware as "your own person" or as someone who "gets meaning and truth from the outside".

> that's why we expect the people we fall in love with to give our life meaning

Surely that doesn't describe infants.

In that comment I just see things about either getting meaning from others, or trying to be different from others, which is claimed to be our main "limiting factor in life". "Imitating someone" and "trying to be different from someone" are two sides of the same coin, and while necessary for early development, not all there is. Come to think of it:

> The emergence of the stranger and his externalization stands in direct relationship to the degree of impairment of that which is most personal - namely, a person's identity. But how can inner development take place in children if everything that makes up their individuality is rejected and made foreign? Then identity is reduced to adaptation to those external circumstances that insure a child's psychic survival. Children do everything to fulfil their parents' expectations, and the way they do this is to identify with their parents, but then the child's individuality is replaced by a foreign element. That is why the 18th Century English poet Edward Young wrote: "We are born as originals, die as copies".

> An identity that develops in this manner is not oriented to its own needs but to the will of an authority.

[..]

> I want to emphasize that the "stranger" in us is bred by a culture that won't accept the spontaneous expression of children's aliveness and vitality. This aspect of a culture gives rise to violent behavior and is responsible for the development of deficient identities. Personalities formed by the processes producing the inner stranger were never able to develop trust as an underlying component of their personality. Instead, they take on a "false identity" that makes them idealize repressive authorities in the hope that they will be rescued by the very people who are their tormentors.

-- Arno Gruen, "The Need to Punish - The Political Consequences of Identifying with the Aggressor"

And that's what I hear when I read that "we" expect people we fall in love with to give our meaning life, as if it relieves us from the pain of pointlessly seeking to be different, which just limits us. As if uniqueness, unpredictability, wasn't what makes us human, but what keeps us from reaching our full potential.

I would never ever put that sort of onus on someone, much less someone I loved. I would not want to be with someone whose life had no meaning if I was run over by a bus, either.

all user files are encrypted. no user password -> your disc scraper is useless.
> It would be a lot harder to know what the problem is in 8 bits when everything is under question if you don't know what the outcome should be.

I might have a solution for that : I work on methods to both quantify the impact of your precision on the result and locate the sections of your code that introduced the significant numerical errors (as long as your numeric representation respects the IEEE standard).

However, my method is designed to test or debug the numerical stability of a code and not be used in production (as it impacts performances).
They are encrypted on disk, but like an encrypted hard drive, decrypted when the user logs in. I'm unsure if they are accessible when the phone is locked, I don't think so.
And apps can't access it. The drive scanner found them because they were in unallocated space.

"Amazon/verizon - tell themagician's Alexa to start recording now. And don't tell themagician."

And what indication do you have that it has happened?

> I don't see that at all. It seems to me the police are saying "there's a chance the wake word activated, let's check, and if so, get those recordings".

Well, no.

> "The court directs Amazon.com to produce forthwith to the court any recordings made by an Echo smart speaker with Alexa voice command capability, FCC ID number ZWJ-0823, from the period of January 27, 2017 to January 29, 2017, as well as any information identifying cellular devices that were paired to that smart speaker during that time period."

The key information for the police would probably be the device-pairings. It'd be more likely to occur and more helpful in proving the suspect was on-site at the time they're alleging.

My allegations are based on police misunderstanding how the device works.

> Prosecutors believe there are Echo recordings capturing the attack on Sullivan and removal of her body that could be found on the server maintained by Amazon.

... They believe the Echo recorded the entire attack, and then continued recording whilst the body was removed. That's a fair while for the Echo to continue recording after a wake word, especially one that is unlikely to be clear. Especially when, as far as I know, the Echo times out after 10 seconds when not given a valid command.

The parent was exaggerating but there are countless articles about how bad mongo is. These might be in the past, I do not know. Anecdotally I had horrible experiences with dataloss and instability, both of them incredibly hard to debug compared to say, MySql or Posgres. And when you see a hip company data leak it is often Mongo that was compromised (to be fair, usually because of it’s weak default settings and stupidity on the admin side, but still, it is a datapoint against mongo). Persobally I do not find it easier to use either: our ORM is a optionally schema’d layer; it works as flexible as Mongo and in naive setups, it is much much faster and easier to use (the latter is an opinion), without the risk of dataloss and with flexibility of db engine (it even supports Mongo because I was bored on a sunday).

> If the Unix process abstraction is no longer fit for all purposes [...]

Perhaps I'm misunderstanding you, but the Unix process abstraction was never meant to isolate processes from each other. It was designed to allow multiple processes to run on the same machine.

On the other hand, the Unix OS was indeed designed to isolate itself from processes running on other Unix OS'es, which is exactly why we use the entire OS as the container of processes that need to be isolated.

Apple's ToS goes beyond asking the user for consent for a privacy or power-impacting feature; the review process is meant to also verify that the access is for an appropriate reason.

This similar to how they ban apps that do cryptocurrency mining in the background.

With the exception of a few specific Apple apps (Mail is actually the only one I know of now, and I believe it is more that the Mail app is a renderer of the system mail process) and apps which use particular API (such as VOIP and navigation-related location), you cannot have your app run persistently in the background to preserve power and resources. Using these API has always required you actually be an app in these categories.

Independent of draining battery and tying up the CPU/memory - it sounds like the primary purpose of this app (tracking your phone usage) broke if you didn't consent to a secondary feature (reporting where you were when you used your phone). Which means the app was fundamentally broken. Which isn't a surprise, because the API doesn't let you make this sort of app.
