I have a Kindle Paperwhite, and one thing that has puzzled me is the light. The light setting has a slider to set the brightness, and the labels recommend a low setting for dark rooms and a high setting for bright rooms.

What puzzles me is that in bright rooms (e.g., all my daytime reading if the window blinds are open) I turn the light all the way off [1]. One of the points of eInk is that you don't need any extra light when you are in a bright room.

Why does Amazon want me to turn the light up, which eats up the battery? I realize it does make the screen look whiter to have the light on in a bright room, but as far as I can see it does not make a noticeable difference in readability.

The new high end eInk Kindle features automatic light adjustment based on a light sensor. If that means that in bright rooms it is going to crank up the light, I would not be happy. Does it do that? If so, can it be overridden?

[1] well, not quite...the light cannot be turned all the way off on the Paperwhite while reading. It only goes all the way off when you put it to sleep.

The formula you cite is a back-of-the-envelope approximation that only works so long as c and d have much smaller magnitudes than a and b. (Try to derive that formula yourself. You'll find it pop up in a limit, but it's certainly not generally true.)

You also need to clear up your own confusion about what exactly you mean by "uncertainty". You seem to go back and forth between several different measures.

Uncertainties aren't negative. But solve the rest of the issues, and what I meant by cases should become more clear.
Yes, 32GB. Although I don't know why it would make a huge difference (not saying it wouldn't).
Oh I would love to create a search engine that would preserve the privacy of its users, but I just don't foresee Google doing that.

I'm aiming at studying Theoretical Cryptography, with an interest in MPC specifically, so this would be right up my alley, but my pessimistic world view tells me that any efforts to create more secure and privacy-preserving services will fail because of institutional opposition and low market demand.
A well-written article, but I disagree with a few of the premises.

First, author mentions that a lot of directors and whoever will still call 911 when things go south. That in no way invalidates general suspicion of cops, especially by citizens not pulling in over seven figures a year. Further, the alternative is to call who, exactly--the article doesn't admit those people any other options, so it's a void point to claim that they pick the only available option and still go on to say that it's a high-quality one. That phone call could still result in action maybe thirty minutes later if at all, as many citizens in poor parts of a city may attest. So, yeah, it's completely reasonable to portray police as overworked/corrupt/incompetent in many situations.

Second, the bit about Star Trek vs Star Wars is cute, but should've also included a comparison with Babylon 5: government agencies (secret and public) alike are shown all along the range of competence, and progress is only made through working together across groups. Author completely neglects to mention modern depictions of competent government agencies (X-Files, Breaking Bad, Stargate, Battlestar Galactica, The Crazies, The Siege, Heat) Author completely neglects to mention past depictions of competent and robust government agencies (A Clockwork Orange, 2001, Starship Troopers, Brazil, A Clear and Present Danger).

Basically, there was a lot of cherry-picking to support the author's point.
$80 more for the higher-DPI Kindle Voyage seems a bit steep. Usually each generation of e-Ink Kindles were roughly the same price but with incremental improvements. I don't see much improvement in the Voyage to justify a big price increase. Plus I wish they'd bring back the physical page-turn buttons. Touch screens and "haptic" responses can't beat old-fashioned buttons.
I left my Kindle on the Caltrain about 2 weeks ago (side note: if you found a Kindle on the Caltrain about 2 weeks ago please let me know!). I guess I picked a pretty good time to need to buy a new one - not totally sure if I can justify the $200 price tag for the voyager just yet.
If you're an iOS user who becomes the target of an investigation by a law enforcement or intelligence agency, remember your data is likely unencrypted in the cloud. So if your device is inaccessible, your email, your location history, your text messages, your phone call history will probably remain accessible. Apple acknowledges, for example, that "iCloud does not encrypt data stored on IMAP mail servers":

In what way is it unhealthy? Aspartame has zero calories, and decades of studies showing its safety.

Put another way, if you want to avoid sugar (which is much less healthy than aspartame), besides water, there's tea, coffee, flavoring mixes like Crystal Light, and various prepared sugar free soft drinks. Many prefer variety over water. There's little scientific basis to believe drinking any of these things are bad. Drinking a mix of these is quite a bit healthier for an adult than chugging juice or sugared drinks - unless you're explicilty trying to carb-load. Milk is a healthy alternative but debatable due to its effects on some.

Sigh... this "where's my feature!" argument almost always comes up.

It is not reasonable to expect that feature X that is very important to you has to carry the same weight for other people.

Some people think that it is unthinkable to write programs without feature X. If you think that way, then Go is probably not a language for you. Note however that there are many people who do not think that absence of feature X is a crippling thing, and do enjoy writing programs in Go.

See the problem here is google and apple and were caught lying over PRISM. So we can't believe anything they say. They are in a unrecoverable position of broken trust. Until I see open source code its just hot air.
Edit:

Can someone confirm or deny the following? I think this is the current state of affairs.

A) Apple will unlock PIN-locked devices by government request, but the best they can do is brute-force. This is very slow, as it can only be done using the phone's on-board crypto hardware (which has a unique burned-in crypto key), and the PIN is stretched with PBKDF2. It has been this way for a while. Apple has no "backdoor" on the PIN or any form of cryptographic advantage here that we know of.

B) The new thing mentioned in the OP's link is that things stored on Apple's servers are now encrypted as well, with your iCloud password.

Is this correct?

I didn't propose to solve any problem, I pointed out the obvious flaws in claims about Apple's security and resistance to gov requests.

Private keys are different than passwords.

Password hashes are computed server side where the password can be trivially intercepted.

CPU backdoors are a security problem, that doesn't negate the existence of other security flaws. Moreover CPU backdoors are far more costly to implement and effort should be directed first at cheaper/easier weaknesses, like ineffective encryption of data.
It seems odd that this book is only about the kernel, given that the BSD camp has always said that an advantage of a BSD over Linux is that a BSD is the whole package, from the GUI and command shell on down, whereas Linux is 'just' the kernel, and relies on distros to be usable.

That is not true. Remember Lavabit.
They do for certain technologies (see CALEA) but even for others they would be required to take reasonable effort to comply with court orders. Intercepting passwords isn't particularly difficult, assuming they don't have them already. Lavabit was required to do something like this.

The implication you inferred from reading the article is that...

I think there reason is that there a misunderstanding here caused by a cultural gap. The Practice of Programming is a very good read which I feel like recommending to every programmer.

> And generics allow you to reuse existing components much cleaner and exceptions allow you to handle errors in a consistent way across the system.

Although I don't think "exceptions allow you to handle errors in a consistent way" (based on my long and still on-going experience with C++), I still don't see how exceptions and generics "ensure consistency across the platform".

You don't build error handling classes in Go.

Based on the public reporting, PRISM collects data via FISA-authorized requests to companies. So Apple is probably covering it in their short paragraph about "National Security Orders from the U.S. government."

Huh? The above comment stated that murder is a very small percentage of crimes, not that murderers are a very small percentage of incarcerated inmates. The comparatively high percentage of people in jail for murder is because murder is 1) more thoroughly investigated and 2) more harshly punished.

In 2010, roughly 1% of violent crimes were murders. [1] Combine this with nonviolent crimes, I'd say that's plausibly a "very small percent".

Not that I'm trying to say murder is not a problem. Killing people is bad, 'mkay.

Yeah, the goal wasn't to create a novel and awesome approach to containerization, but rather a novel and awesome approach to web app hosting and deployment. Containerization is just a tool towards that end.

I feel like everyone fixates on the containerization aspect mostly because Docker is hot right now and containerization is all they do. It's hard to get people to understand that containerization is not the point of Sandstorm. Putting servers under the control of end users is the point.
> though the celeb hacking shows the limits of that approach

Apple has clearly stated that its system was not compromised.

The user reset questions were socially engineered meaning it is irrelevant whether or not the data is encrypted. From Apple's perspective the owner of the data is downloading it.
>It's actually really easy to recover the passcode from iTunes backups

What do you mean by this? I doubt the passcode is stored in plaintext anywhere, and if I recall correctly, the passcode is convolved with the CPU's burned-in crypto key before storage, so you couldn't recover it from a backup without the corresponding phone.
You don't have to guess -- they specify exactly what is encrypted in iCloud;

"On devices running iOS 8, your personal data such as photos,
messages (including attachments), email, contacts, call history,
iTunes content, notes, and reminders is placed under the
protection of your passcode."
That link doesn't support the claim. You can point to random progressive oegsnizations; doesn't mean there was any effect.

I love my Kindle because it got ultimate display compared to any other media device. It's just delighting experience to read in full sunshine. If you try your iDevice(s), you can't see a thing in those conditions. Another great features are of course the battery life and weight. Many manufacturers advertise light tablets, but most of those aren't light. I'll always have my Kindle with me, and it allows me to read tons of stuff during the year. I'm using it more than one hour / day.

According to [1], there are about 600 million apple users, so this translates to 23,000 customers exposed due to government information requests.

I usually simply copy paste the text from PDF and read is as pure text. Of course you'll lose graphics in this case. But that's life. If I need graphics, I might use ebook converter. Anyway, graphics isn't optimal on Kindle usually, so I don't bother too often to do that.
iTunes backups are encrypted by default. And I can't imagine a typical person deliberately disabling it.

Your example is a little unique though because you have physical access to both their computer and their phone. In theory you could just brute force their iTunes backup password.

the article does not mention rvalues and move semantics (i think it's one of the bigest features).

here is an explanation http://stackoverflow.com/questions/6815685/move-semantics-wh...

it is supposed to save extra copies like here

string a("a");
string b("b");

string c = a + b; // creates temporary object that is copied into C by value - the temporary is just a 'full copy'; so that for the temporary it needs an extra allocation and strcpy and free.

the fix is to add the following to the string class

string(string &&r)
{
...
}

string &operator=(string &&r)
{
...
}

so the operator with the && receives and 'rvalue' reference - which is a special reference to just this temprorary and the implementation of this is supposed to swap the data of the temporary with that of the this object; the temporary is then discarded.

While you may be capable of doing that, you are part of a very small set of people. We aren't going to see a revolution where everyone starts using self-hosted applications unless everyone is in fact capable of doing so. And without a large userbase to attract developers, the apps you are running on your personal server will never rival SaaS competitors in quality or variety. That in turn means that even people who are happy with the difficulty of self-hosting today have a lot to gain...

Dominus aims to replace jQuery
Notice the author would still rather use Swift when he's doing fun stuff. I get this sentiment and more than once I've wished there were more constraints in the language to mitigate the damage some kid with a chip on their shoulder could do but it says something about the psychology of programmers, "I know personally I'm good enough to do magical, wizardly stuff with all the cool stuff that Swift gives me but you, well, you need some training wheels so we're gonna use Go for this project".

I don't know about you but I'd rather work with people that understand the tools they are using and when it's OK to do fun stuff and when it is important to exercise restraint and "dumb it down" for the good of the team. Using the language to solve the problem of uneven programmer ability feels a bit off. It's something out of 1984. You can't say "great" in Go you can only say "good++".
