jongraehl··on California Teacher Tenure Laws Ruled Unconstitutional
If teaching in California public schools is messed up, what U.S. state is good for teachers?
jongraehl··on Dash – Beautiful instant offline docs for almost everything
devdocs' C++ doesn't have the first thing I tried (list::erase)
jongraehl··on The day I left my son in the car
I was always allowed and encouraged to open doors+windows while waiting in a car as a child.
jongraehl··on Mac keyboard shortcuts
I love how my 3 year old macbook pro has "alt" and "option" labels on that key that in shortcuts is some awesome unrelated glyph, and the key labeled "control" is in shortcuts described as "^" (which at least is familiar from TTY)
jongraehl··on Introducing the WebKit FTL JIT
wonder how this compares to node - specifically https://github.com/rogerwang/node-webkit
jongraehl··on Scammed
This piece helped me understand that a popular medium.com piece of non-fiction probably isn't "non-". Reddit with pretensions.
jongraehl··on TDD, Straw Men, and Rhetoric
I'd believe the same endorsements from someone who makes their living primarily off working code, rather than selling edu. material promoting test-heavy coding.

That said, rapid "all's still well" feedback is awesome when you can get it.

jongraehl··on Seth Roberts has died
Andrew Gelman posts a eulogy: http://andrewgelman.com/2014/04/30/seth-roberts/
jongraehl··on Google AdSense leak?
Plausible sci-fi.

The scheme described would have leaked immediately. Too obvious and too many people.

jongraehl··on Seth Roberts has died
The incidence of miscalibrated/misoperated ultrasound is high enough that people should hesitate to perform frivolous scans, even though it's probably safe enough when done properly. Cause autism? Doubtful. Cause damage? Sure. Why not be careful?

Seth did report a lot of N=very-small anecdotes uncritically. You might say he was encouraging people to do their own N=1.

jongraehl··on Go 1.3 beta 1 released
It would be defined as sugar for the regular syntax "blah" + var. Not sure what specifically you find confusing.
jongraehl··on Go 1.3 beta 1 released
What? There's absolutely no way for a user string to get scanned for format instructions unless you 'eval' or something like that. The proposed syntax is only for string literals in source code.
jongraehl··on Julie Ann Horvath Describes Sexism and Intimidation Behind Her GitHub Exit
Awful intimidation, my sympathies if true. But why is sexism even in the headline? As far as I can tell, 1. a coworker made advances outside work and acted weird/hostile when rejected, and 2. impromptu sexy hula hoop revue. Incidents 1. and 2. did warrant correction. If HR/founder wouldn't help when asked then I guess you could win a hostile work env. claim w/ a sexist flavor.
jongraehl··on The LeBron James of Programmers
The forces shaping NBA player pay are so unrelated to those in play for programmer salaries that the author sounds shallow when he says that a factor of 4x between max and average in the NBA is why we shouldn't be surprised if there's a similar spread in programmers.

Just as a start, nobody will pay the average basketball player, but the average programmer can earn a nice living. Then move down the line to the owners' monopoly vs players' union, 5 players on the floor, etc.

A better analysis could start with why a 10x more skilled programmer isn't able to produce 10x more value, or, if she is, why she isn't the one capturing it.

There sure are domains where 10 hard working just-competent programmers can outproduce a single genius. Ideally the genius has a few near-peers and a grunt-programming support team, and everyone feels good about that.

jongraehl··on Money and wealth
Wrong; that's only part of it. Strawmanning is when you impute a weak argument to other-side proponents that isn't actually representative, so that you can knock it down, leaving the impression that there remains nothing against your side of the issue.
jongraehl··on Scala – 1 Star – Would Not Program Again
Horribly misinformed. Author didn't learn basics of the language - "val" vs "def" is very fundamental - constant vs. function. Scala does not use Hindley-Milner.

Legit issues: compile time (of course), library docs (maybe), bad HTTP header API (maybe), tooling (maybe). I thought the automatically generated (doxygen style) library docs were fine when I was playing with Scala two years ago.

jongraehl··on Why Scala is the best language available today
> When you make a change you test it live in the REPL. This is no different from running a unit test.

What?

jongraehl··on Did Modern Jews Originate in Italy?
This is outside my personal experience/expertise, so I'll accept your statement about Orthodox conversion, but I'm thinking of things like http://en.wikipedia.org/wiki/Right_of_return#Israel:

"This resulted in several hundreds of thousands of persons fitting the above criteria immigrating to Israel (mainly from the former Soviet Union) but not being recognized as Jews by the Israeli religious authorities, which on the basis of halakha recognize only the child of a Jewish mother as being Jewish."

and http://en.wikipedia.org/wiki/Birthright_Israel "Eligible individuals are those who have at least one parent of recognized Jewish descent."

jongraehl··on Did Modern Jews Originate in Italy?
"If A then B." does not assume A.

We're not making that assumption.

We're talking about A because Israel extends certain privileges only to A-jews. Orthodox jews only accept A-jews.

If there's some explicit cutoff date (N generations back? 1900?) before which there's no brand attached to not having a jewish mother then I guess we should talk about A' instead.

jongraehl··on Ocean acidification due to carbon emissions is at highest for 300m years
So atmospheric carbon breeds?
jongraehl··on No/reduced alcohol leads to increased productivity
There's weak evidence that light drinking (fewer than 3 beers/day) is good for you, or at least not bad (though if you're like me you'll probably notice that you can't manage top-level coding while drunk). I wrote about this a few times in past years: http://graehl.org/tag/alcohol/
jongraehl··on Why I’m Never Going Back to Penny Arcade Expo
Why do these people assume that raped people want them putting on such a noisy rape-is-bad awareness show of "support"? How about advocating for changes that make rape less likely and, if possible, the social consequences to victims less severe? For example: more men than women in the U.S. are raped (though a woman not in prison does have more to fear, rationally).

Getting offended by crude humor is fine as a personal aesthetic choice. Drawing attention to it seems futile.

jongraehl··on Didn't Get Enough Sleep? You Might As Well Be Drunk
Some people may not realize that rational folk are just humoring spiritual scam artists when we offer to test them. We don't actually waste our time investigating the results of some shoddy trial that doesn't catch them cheating.
jongraehl··on From Mr Average to Superman: Craig Davidson's account of using steroids (2008)
I've never used steroids (I don't even lift and haven't for years), but I had the same thought as well. Incredibly dishonest article.
jongraehl··on Cupcake
So, they promise 50gb cloud storage for $5/mo (not initially, but after you sign up and wait 4 years). That's about $5 at current S3 storage prices - http://aws.amazon.com/s3/pricing/

Why not "invest": unproven reliability and performance, uncertain future.

jongraehl··on Explainshell – match command-line arguments to their help text
Nice. Positional arg descriptions are probably hard to automatically find - e.g. http://explainshell.com/explain/tr?args=-sd+G-Z
jongraehl··on He got 1%, we can't hire him
Is a correlation of 0.5 like flipping a coin? No, it isn't. A coin flip would have a correlation of 0. http://en.wikipedia.org/wiki/Correlation_and_dependence
jongraehl··on What Programming a Game in 48 Hours Taught Me About Programming Games
The linked http://strlen.com/java-style-classes-in-c was both horrifying and tantalizing. I'd expected a preprocessor that generates appropriate .hpp/.cpp, but instead I learned about yet another corner of C++ I hadn't exactly induced from experience.
jongraehl··on Paul Graham on CEOs with ‘Strong’ Foreign Accents
I ran into the idea that people are biased against thick accents in '59 seconds':

   "If the gloves don’t fit, you must acquit." Rhyme is actually persuasive. 
   (In general things that are easier to understand/remember are more persuasive; 
    people distrust the same words said in a thick foreign accent, for that reason).

jongraehl··on Use yielding (await) in javascript today, with traceur
I expect coffeescript will incorporate 'await' too.
