Since I think it might not be clear, Amir Sufi's analysis concerns wealth, not income - so the 3rd graph in the article is about wealth, but the first two are about income. The Atlantic article is pretty bad about making this clear, though other reporting of Sufi's research is better.

I am not talking about optimizations that require understandings of the source language. But, for a simple example, a Pascal-ish language may have the statement

x := (a+b)*(c+d)

compile into something like:

_t1 = a + b;
_t2 = c + d;
_t3 = _t1 * _t2;
x = _t3;

in order to simplify translation from an internal representation such as an AST. Putting such a piece of code back into human readable form makes the backend more complicated, while C compiler know how to optimize away the extraneous variables well.

Note that this is just one of many things that contribute to the verbosity of compiler output, not even necessarily a major one in this case.

It's the "do something" mentality of people who value the strength of government over the people.

This way, the government can pat itself on the back, knowing it wouldn't get resistance from the auto industry since, as you said, they're already trickling the tech down.

Why would an auto-industry group applaud the move? They're the bastards who have the power to install rear cameras on 100% of new vehicles. It's all a show.

As an aside: I own a vehicle with a rear camera, and it's an amazing feature. About a month ago, I told a friend "If I were one to support arbitrary government power, I would say we need a law requiring these!". I guess that's the world we live in. The only vehicles that have comparable visibility were old Broncos and large trucks. New cars, with their low-visibility rear windows and high backends, seem to be designed with the intention of getting more people into accidents.

Alright. From the article:

"While the administration delayed the rule, more children died in backover accidents"

Literally a "Think of the children!" argument--which makes sense, because most of those deaths are caused by parents hitting their own kids.

"Soccer mom" is a common phrase used in the US to identify a particular blob of demographic. I'm sure that whatever magical progressive part of the country you're in has stay-at-home dads and everyone uses public transportation, but out in the rest of the US (especially in suburbs) this phrase fits.

It's also a demographic that is well-known for its political advocacy or at least perceived clout: consider all of the terrorist fear-mongering by politicians, and at whom that is directed.

As for paranoia, well, you must not be keeping up with the news. Insurance companies already offer GPS and other trackers for your car to lower premiums, and any number of alphabet soup agencies mine compromised systems for data regularly (as has been made quite obvious).

> Well, it does if they have macro systems like Scheme :)

I wouldn't generally count that because generated code in dynamic languages is (in my experience) an order of magnitude slower anyway.

For example, generated protobuf-parsing code in Python is something crazy like 100x slower than "the same" generated code in C++. Python might not be the best example since it's a lot slower than other dynamic languages like JavaScript or Lua (don't know about Scheme). But in general my experience is that generated code in dynamic languages isn't in the same ballpark as generated code in a low-level language like C/C++ (and probably Rust).

> So we decided to reuse the same compiler infrastructure.

Very interesting. What is the function signature of the generated functions? Are you saying that the functions you generate for serialization are the same (and have the same signature) as the functions you generate for GC tracing?

I think the true enlightenment in this article (for me, at least) is that Windows's tracing framework is far more powerful than I had realized. Being able to capture a system-level trace is an incredibly valuable tool.

Until recently, I had thought that the only real tools out there to do this kind of analysis lived only on Solaris (DTrace). (As I recall, SystemTap gets part of the way, but does not reach far enough into userspace to really get a good view of what's going on -- is that still true?) It would be very interesting to augment Windows's performance tracing tools with some of the other things that DTrace has to offer -- pervasive low-overhead trace scripting seems like it would have made some of the other subsequent analyses that Bruce was working on much easier.

Side cameras are massively inferior to side mirrors. Side cameras give you no parallax or 3d, and don't let you adjust where you are looking by adjusting your head position.

Turn on the front-facing camera on your smartphone and place it face up on your desk. Note that no matter where you move your head, you always see the same patch of ceiling (or your face, if you are over it). Mirrors don't work that way.

Aesthetics, aerodynamics, and cabin noise are poor reasons to do away with mirrors.

I'm researching migrating from Sybase to MySQL and this looks like an interesting alternative considering MariaDB is released under GNU GPL and is a fork of MySQL outside of Oracle control. Are there any weak points in MariaDB worth noting?
Well it's a little more complicated than that: Other than the uniformity problems dual-drbg is a secure PRNG … against anyone who doesn't know the matching discrete log for the parameters.

> As someone running the default mysql install for a SaaS app, are there any downsides to moving to MariaDB?

MariaDB is essentially a drop in replacement; its also faster than MySQL:

https://mariadb.com/kb/en/moving-from-mysql/

https://mariadb.com/kb/en/mariadb-vs-mysql-compatibility/

"For all practical purposes, MariaDB is a binary drop in replacement of the same MySQL version (for example MySQL 5.1 -> MariaDB 5.1, MariaDB 5.2 & MariaDB 5.3 are compatible. MySQL 5.5 will be compatible with MariaDB 5.5)."

"This means that for most cases, you can just uninstall MySQL and install MariaDB and you are good to go. (No need to convert any datafiles if you use same main version, like 5.1). You must however still run mysql_upgrade to finish the upgrade. This is needed to ensure that your mysql privilege and event tables are updated with the new fields MariaDB uses."

See the third photo in this article for a dramatic illustration of how much cannot be seen from the driver's position with mirrors or by turning to look through the rear window on some common vehicles: http://www.drivearabia.com/news/2009/03/04/product-review-pa...

Drivers tend to massively overestimate how much they can see behind them.
Can we name one of them that uses Dual_EC, and has been shown to do so? I know a little about BSafe, and my impression is that most programs that use it don't use it to get TLS, which their OS already provides. Feel free to correct me if you've got more BSafe experience than I do.

'Small' Nuclear War Could Trigger Catastrophic Cooling
Ignoring the regulation for a moment, current camera systems are a bit lacking. Those of us who had good driver training will always look over our shoulder when reversing, occasionally checking the near-side mirror if needed. Facing forward to use a screen feels weird. And it's worse than that:

Reversing cameras always send their output to the big screen on the center console, which is bad for three reasons:

1. It's low down, so you lose part of your peripheral vision which ends up just picking up the car's interior.

2. When you're reversing on a road, but facing forwards to look at the screen, you can't see out the side windows to check for approaching cars heading towards your rear.

3. Your peripheral vision is further affected by your focus on a narrow, highly detailed area - that 9" screen showing a wide-angle view. Your brain concentrates just on that 'important' area. It's entirely different to looking out the back window when everything is at the same scale, peripheral and central. You end up being forced to trust the screen completely, which just isn't sensible.

Having tried a few on rental cars, I'm very uncomfortable with the constant attention swapping you end up doing between the screen and the rear window.

These cameras can only be beneficial to people backing out of driveways (which is the point of the law), but they're not a panacea and I'm not convinced they're a substitute for an alert driver using mirrors and windows. A useful additional tool, for sure, but will they be used that way? An audible proximity alarm feels like a more reasonable thing to mandate to me.
Cracking Acquia Drupal Certification
I wonder if anyone has investigated the effect that back-up cameras have on mirror usage.

It may be that by having drivers take their eyes off the mirrors when backing up (because they're now looking at the camera display on the dash), they won't be alert to vehicles approaching from the sides. It seems to me that this could increase the likelihood of pulling out in front of someone, and increasing that kind of crash.

As with red-light cameras, it seems like there might be unintended consequences that someone should look at.

Back-up deaths constitute 210 deaths per year, of 34k auto deaths anually (2012)?

And this technology is only estimated to prevent 33% of them (60-70)?

I guess every little 0.2% safety improvement is good if it's free... but I'm not sure this is the most cost effective way to increase car safety.

(Roll cages; higher standards for airbags and various types of collision for occupants; crumple zones for pedestrians; self-driving cars (if you're going to go full-sensor anyway, why involve a human at all).)
Manure storage and getting through the winter.
We don't have to estimate this from news reports, according to the article they have already done the math and expect it to save "between 59 and 69 deaths per year".

I agree that's not a lot compared to the total number (34,080 deaths in 2012). It would be interesting to see the cost per life, how much does the camera increase the car price?
I don't feel like I actively avoid white lies, but I can't think of many that I've told recently. When I was a kid, sure, I'd lie to my parents about little things, and in school I would invent or exaggerate excuses for late assignments, etc. But now I don't feel like there's much need to do that.

Of course, when you get into simplification and omission, things get more complicated. I've absolutely simplified basic things like where I'm from, or the exact timeline of my education, etc. And every time I say anything, I'm omitting, well, everyone that I don't say. The line there is definitely blurry.
Yes, we do have around that number of tables which reflected into those thousands of models. Many of them are related to storing 'frozen' regulation data. One example: every X time we need to create something very similar to a IRS forms (electronic) and send it to a bunch of government agencies because the data sent must be available for reports we can't just store a text file. One of those regulations requires hundreds of tables:

https://www.fazenda.sp.gov.br/sped/downloads/GUIA_PRATICO_DA...

Some systems are very sensitive to transient data and pretty much needs to store all of it, depending on how you plan to use that data later it can add a good number of tables to your software.
