hessenwolf··on Germans, still outraged by NSA spying, learn their country may have helped
How familiar with Russia are you, by the way? Maybe if we trade backgrounds, the conversation could proceed more interestingly... My contacts are mostly through my wife, so I hear it from St. Petersburg, North Ossetia, Georgia, and the Ukraine, with a slightly over-representative Jewish tint. I am none of the aforenamed.

Do you remember pre-Putin? It was an effing disaster.
hessenwolf··on Germans, still outraged by NSA spying, learn their country may have helped
I think that Putin is the band-aid Russian needed ten years ago, but gone mouldy for a few years now.

Mugabe, yes, initially wanted to redistribute the land wonderfully... didn't totally think that one through.

I just mean to say that integrity and competence are not analogues.

hessenwolf··on What every computer science major should know (2011)
Thanks for the reference. I was rather disappointed with Tufte's works, given all the hype. There were too many specialised "arty" graphs, and not enough standardised methods.

The rules of work.

For writing clean code, at least maybe start with the Python style guide.

hessenwolf··on What every computer science major should know (2011)
Every computer science major should build a portfolio?

Ahem, excuse me, but I've been employed. I kinda don't live off Mummy and Daddy and need to eat and pay rent.

May I throw in a gigantic go fudge yourself in there, you elitist prat.

Would you rather a corrupt politician than made the country rich (Haughey, Putin) or an honest politician that made the country poor (Mugabe)?
hessenwolf··on The Data Science Handbook
Mmph. Ja. Skimmed the first three chapters. Not guru material.
hessenwolf··on Statistics: P values are just the tip of the iceberg
I guess you mean clinical significance.

http://www.bmj.com/content/348/bmj.g2130

This is a secondary issue. For most non-stats people, I wouldn't recommend the confidence interval as a measure of clinical significance. I'd rather look at the actual distribution of the two effects and view quantiles of the predictive interval.

And, yes, in hypthoesis testing, p-values and confidence intervals are generally interchangeable. All they speak of is the overlap of the sample distribution of means, really.

hessenwolf··on Statistics: P values are just the tip of the iceberg
p-value testing and confidence interval testing are not interchangeable?

also, p-values are used to determine the number of effects in a mixed model, or the number of factors in an ANOVA, etc. Sometimes confidence intervals on abstract parameters can be a bit less useful.

hessenwolf··on Statistics: P values are just the tip of the iceberg
p-values are extremely useful for two things:

1. Teaching people who specialise in context areas (chemists, engineers) a pragmatic way to make a decision from data in the presence of randomness.

2. Automating analyses. (remember your Benjamini-Hochberg)

I'd never actually use it myself. Jeepers, just look at the picture.

hessenwolf··on Google Sued by Job Candidate for Age Discrimination
Nah, the documentation package is about 40 pages. The cv though, yes, is about 2 pages. I included a 1 page resume, and a 3-4 page curriculum vitae, to get around the annoyance of having a wide variety of experience, yet wanting to be terse, and to avoid the whole, "I see you have programmed in C++, but we needed a C programmer" problem.
hessenwolf··on Google Sued by Job Candidate for Age Discrimination
Or you could all choose the German solution...

1. A photo on your cv. Or it goes in the bin.

2. Birth date.

3. Marital status and children.

4. Every educational achievement documented officially since highschool.

5. Every working position with an official written reference, in deeply codified form, written mandatorily by your boss, who probably inspired you to want a new job in teh first place. The last company I left had a secret ten factor 5 level numeric rating system, which was then translated into the codified text by the personel department.

hessenwolf··on My Girlfriend Dissociated and Forgot Who I Was
Ah. Good explanation.

So that's why my ex didn't remember things. I read about it, but I could never quite put my finger on what the dissociation stuff was.

hessenwolf··on A ‘Rebel’ Without a Ph.D (2014)
It happened at my university (and I did some moonlighting contracting statistical analyses for some). The salary rules changed to motivate them.
hessenwolf··on Using Private Email, Hillary Clinton Thwarted Record Requests
Is the idea to attack her early so it burns out early, or is this genuinely to attack her? These articles really read like an episode of House of Cards.
hessenwolf··on A ‘Rebel’ Without a Ph.D (2014)
Expect a sweep of middle-aged professors doing PhDs with their mates supervising and examining.
hessenwolf··on Stuff I've Messed Up While Interviewing
Things I have screwed up:

1. No ability to do mental arithmetic whatsoever.

2. No ability to write standard template library-based C++ code from memory, except maybe cout and cin.

3. Being late. (3 times at least)

4. Being in a different country and forgetting about it.

5. Trying to sell myself because that is what I was told to do and coming across as unforgiveably arrogant. (a difficult balance)

6. When asked about if I minded the data-cleaning work, which could be boring, I joked that if I was worried about being bored I would have chosen a different career. Maybe this isn't even a joke. Either way, highly offended interviewer.

7. Couldn't really speak the language.

8. When interviewing for a position as a bartender, said I could pour beer. Then proceeded to spray the customers with my attempt when I was asked to prove it. (I was young) However, the bar owner then let me work for free as a trainee for the night, and I got the next job.

hessenwolf··on ‘Unsubstantiated’ child neglect finding for free-range parents
Yeah, fear of landing in gaol/jail/prison, or your silly children landing in jail, is a pretty big thing. Consider also that jail in America is rather famous for being awful...

% of population of Germany in prison: 0.076%

% of population of US in prison: 0.707%

% of population of Canada in prison: 0.118%

hessenwolf··on Understanding Variance, Co-Variance, and Correlation
It looks like an enthusiastic newbie with some clipart and an equation. Fair play for trying.

I would suggest adding the following.

1. What the poster above said.

2. The reason for the E[(x_{bar} - x_i)^2] choice. Why not E[|x_{bar} - x_i|]? Was it a mathematical convencience? Was it, perhaps, because Gauss had the integral of e_{t^2} from -Inf to plus Inf lying around in a letter from Laplace?

3. It is an equation with a square. Use a square somewhere.

4. The square root of the variance happens to be the horizontal distance between the mean and the point of inflection in the normal distribution. How cool is that?

hessenwolf··on The ‘Loser Edit’ That Awaits Us All
Yeah, and it would be awesome if we didn't have to have squeaky clean, unrealistic politicians. That is a really small sample of people, who are a) weirdly repressed, or b) amazing liers.
hessenwolf··on Pentagon’s $55B mystery plane is secret, but debate on cost is appearing
Wasn't war always about stealing people's stuff or preventing your stuff from being stolen? I mean, my country had independence wars every generation for 800 years, but they were all about not getting our potatoes robbed.
hessenwolf··on Pentagon’s $55B mystery plane is secret, but debate on cost is appearing
America is unlikely to be dumb enough to fight a war in China and Russia, but a proxy war with China and/or Russia is likely. Russia had some key victories with really simple mass produced blanket bombing kit, simple tanks, ak47s, etc (there to be good at putting old crap together to build your solution: находчиво (nahohdchihvy)).
hessenwolf··on What It’s Like to Need Hardly Any Sleep
35, and I get my preliminary overnight monitor on Monday. I usually sleep 6 hours, waking up every 90 minutes to check on the world, but I find it really hard to get out of bed.

I recorded myself using snorecycle. Yeah, so, my snoring gets progressively louder, until I stop breathing and wake myself up. :( It's only taken my wife three years to convince me.

hessenwolf··on Stephen King's “Everything You Need to Know About Writing Successfully”
Hell no. Crack, crack, knees and back.
hessenwolf··on Bradley Horowitz Is Now Running Google+
Much like any fashion, I think it is a bit more likely it will be drawing on its k unique predecessors :).

I saw jean flares in a designer shop yesterday. Really? Again?

hessenwolf··on Coding is not the new literacy
I couldn't agree with you more. I have been working on trying to get some skills therein. I paste the notes from my personal expertise board.

Graphic Design:

Relationship

Transition

Layering

Principles of Design:

Repetition

Opposition: Excitement and tension. Too much is bad. Particularly thick and thin lines in logos.

Priority: The order of the items.

Position: Use a grid. Divide in twos and connect corners diagonally.

Attributes of Design:

Balance: Arrangements so that elements equal each other, not overpowering each other. Can balance objects with each other or whitespace with objects.

Emphasis and Contrast: too little is boring, too much irritating. Plain text with bold or underline in small quantities works.

Rhythm: regular movemet, reduce line spacing or tighten words to increase speed. You can increase the line height, but too much and the eye has trouble finding the next point. The rhythm should fade out, and not end abrubtly.

Position:

Grid Choices

http://www.troytempleman.com/2010/04/30/grids-in-graphic-des...

Rule of Thirds

Golden Ratio

Columns

Baseline Grid http://www.markboulton.co.uk/journal/five-simple-steps-to-de...

Start with a symmetric plus, and then use 1.414 ratios to create smaller sections with margins.

hessenwolf··on Why phone and whiteboard interviews are not the best way to evaluate candidates
The solution is like the blog author's (maybe it was a different blog I read this morning): practice interview questions. Study for the exam.

Yeah, I can do that. Mmmm. And maybe I pass. But other companies won't make me do that...

So, if the aim was screening for people that want to work for Google above all else, then, yes, the screening totally works. But... Google would downsize you and your project coldly if there were financial reason to do so, so...

hessenwolf··on Sans Bullshit Sans
I expected it to pick up Big Data. (not that I am against key-value stores)
hessenwolf··on Henry VIII's evidence to support break with Rome turns up in Cornish library
Exploring the counterfactual allows us to reveal holes in our understanding, by setting up hypotheses and allowing them to be knocked down by argument. And it's fun.
