I know you're not just looking for answers but a pointer to some better documentation, and I can't provide you with those, but:

> why IVs shouldn't be considered secret

The least is considered secret, the least can be leaked and cause problems.

> why the IV isn't required to be able to decrypt the file again

The IV is required to decrypt the file again. In the linked document's design the IV is actually the encryption key, which means it is known by the receiver, which is why it's not included. But that is just a special case that should never be reproduced.

> Being "concise" is not one I've seen argued

Really? Lisp is the most concise and clear language I've ever used. There is almost zero boilerplate when writing it.

The example was a simple one to get the idea across, you can create your own functions and do the same too:

(my-let [a 1
b 2
c 3])

my-let could be a macro that compiles to a normal 'let', while also recording all variable names for some other use, or adding logging, or whatever you want. Another concise example is the -> macro to pass the result of a function in as the first arg of the next function:

(-> a b c d e f)

instead of

(f(e(d(c(b(a))))))

These can all be argued against I'm sure as they are still simple. Check out some example code written in Clojure for a better view of conciseness [1]

Dentistry in other non-USA countries is much less regulated than medicine (which is pretty much socialized). So in Israel, if you want to make money, you become a dentist rather than a doctor.
It seems like the wrong success metrics are used here if this isn't an experiment. If they used something like "more clicks on articles" this change could appear positive from their end since people now have to click the articles to actually see if they want to read it.

As far as mobile goes, iOS has some compelling advantages. In particular, you don't have the headache of supporting all the different Android devices. Plus, despite the difference in raw numbers of devices, iOS offerings often bring in as much or more money than the Android version.
no expert at all; was before my time -

But probably worth spending some time with ITS, TOPS-10, and TOPS-20 & digging around with TECO and its descendants which came to be emacs, and probably checking into 4.2/4.3BSD as well..

The former group is pretty much the platform for early LISP (when lisp was still in caps :b ), and the latter, well, alot of good stuff happened here.. plus built in franz lisp and the lisp mode for (real) vi ..
That's a very convincing argument but do you have any evidence to back up those claims?

Extraordinary claims require extraordinary evidence, I think it's fair to dismiss those claims until they're capable of coming with a better justification than "I developed an entirely new type of cryptanalysis theory to achieve this."

"Between roughly 1890 (Sherman Act) and 1982 (Reagan administration antitrust guidelines) the US authorities were mainly concerned with competition too (breakup of Standard Oil: 1911; breakup of Bell System: 1984)."

This is the wrong timeline.
The spectrum shifted towards consumer welfare very early on (right after standard oil), because they found the legal definitions in the sherman act too broad to be useful (every contract is a restraint of trade).

If you read the bell cases, etc that you cite, they were already focused on consumer welfare.

This is because otherwise the bounds of antitrust are limitless.
Every competition between businesses harms a business :)

Also note: The AT&T case was settled. The original case was filed in 1949, not 1984.
You can see this in the 1982 settlement, which is a modification of the final judgment from 1956:

The speed of the machine is mostly a function of the mechanical feed speed of the parts. This is the hopper/belt mechanism and it is by far the slowest part of the machine.

Once the parts are on the recognition belt things more very fast, a single part can be scanned and recognized in about 30 milliseconds, so roughly 30 parts / second.

Making the machine much faster then means making that feed mechanism faster than it is today (roughly 1 part per second tops) and that's the challenge I'm looking at right now. Ideas more than welcome! Even bad ones, you never know which bad idea with a twist can become a good idea or even a very good idea.
That's a strange observation.

Captain Comic 2 seems to be almost impossible to find a working copy of. It seems it had some sort of copy protection that when the files were copied it locked you out of a majority of the game.

I don't understand what "value" means here. There is a large number of "jobs", maybe even majority of jobs, which without a modern society would not function. Would you then calculate the value of these jobs as the value of modern society divided by the number of employed people with the given job?

"Virtuous" and "vicious" cycles both refer to positive feedback, and differ only in value judgement they imply, so arguably the value judgement is the entire point of using these terms. I can't think of a common use term for negative feedback off the top of my head.
Here is a guide I have developed over 6 years when I dove into copmuter vision around 2011. My path has been self taught until recently I took a graduate course.

I started from wanting to develop AR apps during my undergrad, Here are the best resources I have found to date:

Computer Vision is very theoretical and experimental, so the more hands on, the better! My approach has been to go top-down, overview the landscape and slowly progress deeper.

Begin with the best library for CV in my opinion: OpenCV. The tutorials are amazing!

Python tutorials: http://docs.opencv.org/3.0-beta/doc/py_tutorials/py_tutorial...

C++ tutorials: http://docs.opencv.org/3.0-beta/doc/tutorials/tutorials.html

Immerse yourself in these and build any apps you think of!

Then go into:
pyimagesearch tutorials http://www.pyimagesearch.com/
and aishack.in http://aishack.in/,

tons of great tutorials to learn different topics of vision with coding walkthroughs. Understand the examples and rewrite applications.

Then Dive Deep:

Get the new OpenCV3 book, a nice deep overview of many topics in computer vision. https://www.amazon.com/Learning-OpenCV-Computer-Vision-Libra...

And watch this course on youtube:

https://www.youtube.com/watch?v=skaQfPQFSyY&list=PL4B3F8D4A5...

I feel like then, you will have so much exposure that when you dive into formal classes and textbooks, you will really understand and be enlightened.

This was the general way I learned computer vision, and recently I completed a cv internship for nanit.com . I was not hired for my formal knowledge, but they were impressed by all the various projects ive done and knowledge I had on many vision topics.

I also recently took a formal course of vision at Cornell:
http://www.cs.cornell.edu/courses/cs5670/2017sp/

All the assignments have starter code in python and opencv.
This was an amazing class as it dove deep into 3D computer vision, which is so relevant to augmented reality!

Also, here is a link opencv examples for iOS: https://github.com/Itseez/opencv_for_ios_book_samples

here are links for opencv example for Android: https://web.stanford.edu/class/ee368/Android/

Hope this helps! Shoot me a dm if you or anyone has more questions!
That was my exact thought as well. I paid $8000 for my bootcamp. I'm 18 months into an average of 65k over that time. So in that 18 months I'd already have paid in the area of $16k, and assuming I don't get a raise double that over the 3 years.

Also, I'm curious the arrangement for contract work that the developer does on his own time. If they charge a percentage of that, I'd have paid them more than a downpayment on a house over the course of 3 years.
This is an unpopular opinion, but nobody knows how to make anything look real. The quicker you accept and internalize this, the easier it is to dive into graphics programming. It reveals graphics programming for what it is: A bag of tricks that mostly look good in certain constrained circumstances.

When I first started out, I chased book after book looking for knowledge. "Someone must know how to make things look real, right? Everyone is talking so authoritatively on the topic." No, no one knows. There's no source of knowledge that represents the cutting edge of the field, because the cutting edge is whatever happens to look pretty good today. And that's mostly thanks to very good art, not very good techniques.

Just dive in and start doing geometric puzzles. Look at it like a game, not like a quest for knowledge. If you have fun with it you'll go further than any book will take you.

But look at energy per volume [1]:

Diesel: 35.8 MJ/L

Hydrogen: 9.17 MJ/L at 700 bar (10,000 psi).

It will require a tank of 4x the volume for the same energy which comes with many additional challenges. Plus, a tank that can withstand 700 bar will have to be extremely strong and heavy which hurts your energy/mass ratio.

> no-one actually crosses it

That's not entirely true but I believe it's more true today than it was 20 or 30 years ago.

For all their, significant, faults, when Grammar schools were prevalent they were a vehicle for practical social mobility i.e. people whose parents had done manual work getting well educated and finding professional jobs.

That's not true with Grammar schools today, their rarity causing entry pressure that has the effect of limiting the majority of students to children of the professional classes. Also, the Grammar system was/is hugely prejudicial. Although it was an avenue for social mobility that doesn't mean that it was an effective social good.

Increased university participation has increased educational levels but doesn't appear to have had a commensurate increase in professional labour either.

To some extent I agree with the article: it's not clear to me that social mobility should be an end to itself. However, I tend to agree with the New Labour idea of equality of opportunity in preference to the old Labour idea of straight equality. As such, the conclusion that changes in the ownership of capital will sort everything out doesn't strike me as having much evidence.

Using that philosophy, we have to be cautious about whether or not the Riemann hypothesis has been solved every time someone uploads a paper claiming a proof to arXiv, even if it's nonsensical (which this "proof" is), just because we haven't had a team of mathematicians peer review it.
