I understand, but we need you to give us the experience and omit the dismissal. The former can dramatically improve the quality of this site; the latter only degrades it. And the former will actually be persuasive while the latter merely gets people's backs up (or makes them cheer if they happen to hate the same thing) without teaching the reader.

I get irritated at having to repeat the same things over and over, too, but the internet is basically stateless and so (sadly) is the software business. And like everyone, I get peevish when people say/do wrong things and act like they know what they don't. The longer one has been around, the more occasions one has to secrete bile. But it's a humor one must metabolize internally and not release into the community—hard work and not fun at first, but far more rewarding in its effects, and maybe our only chance at creating an actually functional culture.
Interesting! They mention [1] that they use a spectrometer and innovative algorithms to detect CO2. I would expect that to be hard.

Riding around SF is really all about knowing which streets are good for bikers. Many major streets with no hills have bike lanes (Valencia, Polk, Market, Embarcadero, etc). I have not felt in danger of being hit by a car riding on those streets for the majority of my ride.
What incentivizes professors to grade honestly? Nothing
How did you account for a woman having many more times the matches of a man? Wouldn't this influence whether they would be willing to "spend" time on the match?
The full calculation would also need to take in to consideration wastage / spoilage; crop failure; loss to pests; nutrient density (probably can't thrive off potatoes and corn only); animal feed (pets as well as animals for food).

Having said that, I'll now go on to say: with one inhabited planet there are limits to resources, but the limits to human resourcefulness are undefined.
> Given the chance, teachers and school administrators will cheat on them.

I know. This can be mitigated by swapping the anonymized test sheets with other schools to be graded.
I'm actually arguing the exact opposite. It's better to make changes that fix obvious issues that don't break anything in practice rather than to adhere to some academic notion of "complete" backwards compatibility.
Arable land (% of land area)
I don't have an e-bike but I agree completely. The only downside to my bike is that I can't really go anywhere in nice clothes because I'm likely to break a sweat. An e-bike would be a true all-purpose city vehicle.
I can compare to biking in France and Germany, and it's much more dangerous in SF.

Most of the drivers don't know to share the road with bicycles and don't respect cyclist in general. The other day I was hit by a car on purpose.

I'll take a stab at this:

I see three round things and rotating things below that

It's some variation on this variable autotransformer: https://en.wikipedia.org/wiki/Autotransformer#Variable_autot...

that's a way to gradually increase voltage.

I was also more than vaguely disturbed by how casually he was operating. That bulb perched on a stool didn't seem all that stable. But as you say, "he probably knows what he's doing".

how do you get that amount of power in a house?

"two hundred amp service" is very common in the USA. I just checked the breakers in my garage. My main breaker is labelled 200 Amps. It has two "poles". Which means there are two separate 120 Volt inputs (referenced to Neutral). The inputs are 180 degrees out of phase, so across them is 240 Volts. 240 * 200 = 48,000 watts.
Many of the folks considering e-bikes here are not generally comparing them to traditional bikes, but rather with cars. In which case all of the negatives you cite here, become positives.

Emits signals all night is quite an exaggeration. Unless the phone is actively transmitting or receiving something, it only checks in with the network every once in a while.

I'm not sure about exact times in 3g/4g, but 2g (GSM at least) phones caused audible interference with poorly shielded audio equipment when they were transmitting. I recall an otherwise idle phone only checking in once an hour or so, though the interval was/is probably defined by the network, so that maybe different at different locations. Still, for power saving reasons, I expect an idle phone to just sit quiet most of the time.

CS Syd – Overcoming Boolean Blindness with Evidence
"For instance it doesn't have everything you need to validate certificates..."

Yet it has all the CA crap thrown in, via the overloaded openssl binary. As "examples". And according to the documentation, not even "correct" illustrations of how libssl should be used.

Encryption and authentication are two separate problems.

Just because you figured out a way to encrypt a message does not mean you have also figured out how to a way to send it to only the correct recipient... over an insecure network. (Insecure not only in the sense of "plaintext" but in the sense you are not in control of much of anything - routing, PKI infrastructure, etc.)

It seems to me that one would want to solve the authentication problem first, and then move on to encryption.

This comment shows that for proponents of using SSL on the public web, it's been the other way around. Authentication was never sorted out.

When it comes to authentication, all due respect to the OpenSSL authors, SSH has provided a better attempt at a solution than any implementation of PKI using SSL/TLS.

And one more thing, how many ciphers does a user really need? As we've heard time and again, many of them are not even "safe" to use. Some of the alternative SSL libraries have wisely removed them. But I guess OpenSSL is append only?

Don't think so. Things are much more resilient that side in the sense that working around things that don't work is just another normal day.
>Checking if a throw resulted in a capture server-side would be weird, I don't see why it couldn't be done on the client. //

It locks up [server access icon spins] a lot on the point at which the ball closes and the game is deciding whether to capture or release the pokemon (what's the heuristic there?), often crashes at that point to.

I wouldn't be surprised if this is because it's sending the whole of the swipe data to the server. Surely it doesn't need to check if there are pokeballs available, when your client says "gotcha" then the server will have record of if there were balls available or not.

So has the author read all these books? Is there a review? What makes these the best? Isn’t a significant part of the content in these books overlapping?

What is someone who isn’t a graduate student algebraist supposed to take away from a list of 33 books? At typical textbook prices, that’s like $4000 and 5 years of doing nothing but reading about linear algebra.

(Sorry if this sounds negative; I’m sure there’s some audience who will find this list useful.)
If there were protected bike lanes along my commute (about 3 miles), I'd cycle to work in a heartbeat. (Well, showers at the office, preferably clean ones, would also help.)

Instead, only about 25% of the trip has bike lanes at all. And they share a curb with the buses (which might be the worst arrangement possible, since cyclists and bus drivers have to keep dodging one another in and out of the lane - endangering the cyclists and slowing the buses).

Instead, I walk when the weather is right. Cycling right beside cars would scare the shit out of me.

Most major apps phone home for a big config object (likely JSON) at the start of a run. This would contain things like car icons, etc. You can see an example of this in the 3p Uber API which has a call to get which car types are available at a given geolocation. This API returns not only the vehicle types (Uber X, Uber Black, etc) but also a jpeg icon representing the car. In this way Uber can roll out new car types in locations without a client side update.

I'm biased for this next part (since I work on the product) but if you're interested in making your app have abilities like this check out Firebase Remote Config (https://firebase.google.com/docs/remote-config/). While setting up your own config service is not rocket science, having a free one with a web UI is pretty nice.
I agree, I think many novice cyclists inadvertently put themselves in dicey situations by being "too nice" to car traffic. It truly is safer to be visible and temporarily "in the way" than to ride in the door zone or gutter and risk getting doored, side-swiped or right-hooked.

Being nice might momentarily appease an impatient driver, but it puts the cyclist at risk and makes them appear erratic to other traffic.
I really hope that motorcycles make a comeback as well. They are incredibly fuel efficient, they don't take up nearly as much room, are far cheaper to buy and maintain than cars, and a heck of a lot of fun.

That's the point. If the EU is more homogeneous and it has some serious issues, then a similar union in somewhere with even greater diversity may be prone to the same issues or worse (note: I'm just paraphrasing the poster for clarification - I'm not knowledgable enough on the AU to comment on whether this is true)
Aren't backups basically a guarantee that you can never ever delete anything from anyone's server? Even if you hit delete on an email/post/photo/etc. if they made a backup before then, your data will now forever live on in some vault or maybe just Amazon Glacier.

A straight line border is usually an indicator that it was artificially imposed by a group of people who had never been to the border being defined and did not give a shit about the existing cultural groupings that they were arbitrarily cutting into sections. Africa has a lot of them because it was colonised and split by European powers. Is that what you were looking for? And why on earth do you think that reducing the power of these artificial groupings would be a negative because of how artificial they are?
Keepass seems like a questionable choice, seeing as it's very unlikely to be affected by any particularly interesting bugs.

Besides the crypto, there's not much to break and breaking the crypto requires access that would in almost all cases allow for far easier attacks against it (i.e. wait for user to decrypt the passwords).
A related question: Where do you, as a marketer, draw the line between producing a product to serve the needs and interests of a particular market and enabling activities you disagree with or believe to be harmful (even if only harmful to the consumer)?

In this case, writing for the "prepper" audience seems to fall near the line of providing content relevant to the consumers' interests and enabling/encouraging paranoid 'end-of-times' behavior that at best prepares the consumer for a natural disaster and at worst entrenches distrust of society in the audience.

Is it possible to ethically market a product that relies on a belief system or set of values you disagree with?

CVE-2016-6213 was reported three years ago by OpenVZ developer
I thought that's why coral was used for bone implants it's first shaped like the part needed then once implanted your own bone cells gradually take over.

Maybe it was just a trial I saw to see if it worked or maybe it can only be used for small patches not entire sections of bone like a femur or hip joint.
Actually, I think it's very similar to Axler's in spirit. Not numerical at all (there is a description of the min squares problem, but that's it as far as I remember).
Matrices are used more explicitely than in Axler, but only when necessary, because the author claims he's an operator theorist so the focus is on linear operators.
Determinants are introduced as multi-linear functionals and are not avoided as in Axler.
Supporting the fact that the book is quite theoretical, this is what you can find in the last chapters:

Chapter 6. Structure of operators in inner product spaces.
Chapter 7. Bilinear and quadratic forms
Chapter 8. Dual spaces and tensors
Chapter 9. Advanced spectral theory

Unfortunately I'm not familiar with the Russian books.

the "three round things" probably are controllable transformers to set the voltage.

At least the electrical equipment seems properly build and hooked up, so it should be fairly safe. I'd imagine the bulb breaking/falling over wouldn't be pretty through, and I would prefer that to be caged in and properly mounted...

At least here in Germany 20 kW is commonly available in a normal home power-connection. An electric water heater (for showers etc, not the electric-kettle type ;)) has 20 kW or more as well.

"but my name's Jim...."
Honestly, I'm not even sure how much a review would help either. I struggled quite a bit with linear algebra in school with Curtis' Abstract Linear Algebra, and eventually I decided to hole up in the math library for the better part of a week and went through every linear algebra book they had (definitely more than 33) to find the best supplementary material. I guess it was a pretty hard class because about half of the other students had the same idea. None of us settled on the same book as our favorite.

My sample size is exceptionally small, but the opinion I took away was that linear algebra was just one of those things you have to plod through lots of books to find the one that works for you.

Which is still sort of outrageous in a quite empty place like the US. The people consuming the energy should be paying for a nice setback from the power plant.

I guess a complicating factor is that access to water makes it easier to run a power plant and is also something desirable for residential areas. I'm sitting about 2 miles from a now shuttered coal plant. So is about 1/3 of the population of the county, because the towns developed by the water, before electrification.
It is somewhat different because you need to convince other mail servers to cooperate with yours whereas the HTTPS server works directly with clients (browsers) and may function completely independently.

They are an arrogant company with zero suspicion of the limits of their own knowledge. Before they started spouting off about their "We're putting a bullet through Google's head" nonsense I tried engaging with their management. About an interesting phone concept that I have / had.

What does the comment about not using authentication mean? What would be authenticated in this case?

I think I'm in a bit over my head looking at the code, but does the author mean that somehow the data should be verified to come from a trusted source first? But doesn't the attacker have to have some of the encrypted data first for that to be meaningful?

Interesting. I almost though this was going to be an advertisement for Swift, since I saw this exact argument in a WWDC talk.

Apple calls Swift a "protocol-oriented" programming language, and with the addition of first class value types, tries to solve these problems in their own way.

I'd definitely suggest people frustrated by the problems outlined in this post to check out the Apple talk on protocol-oriented programming in Swift.

These are interesting exercises. I would also add that what it means to learn, or begin to learn, a language in general but R in particular could vary widely.

Some people actually need to learn statistics while they are learning to express those concepts.

Some people need to learn idiomatic R. I really didn't think of R as very functional till I took Peng's (excellent) Coursera course.

Some people need to get a sense of the libraries available.
