Google allows Multi-variate tests again (5 years after Google Website Optimizer shutdown in 2012):

Now their Multi-variate tests look more user-friendly.
Google Optimizer also allows up to 10M requests per month, which is much, much higher than what Optimizely allows.

However I am not sure if multi-variate testing (or A/B testing) would worth our time to use them. Usually such experiments are quite time-consuming and lead only to a barely noticeable improvements (if at all).

After that I opened this ticket:

How else could I contact dreamwidth to find out why my account was suspended?

When user changes a password on a web site - does web site have to expire all authentication cookies of that web site that that user has in all browsers?

I noticed that if I signed in to Gmail from two browsers, and then change password in one of these browsers, then Gmail still allows me to browse email in another browser.
However it also shows red message that functionality is limited due to password change and gives a sing in link.

Is it important from security perspective to end old user's sessions ASAP?

That interview causes cognitive dissonance.
Of course UAE is an advanced country with GDP per Capita $43K (below the US, but above UK).
But UAE not exactly the most technologically advanced country. They are on a consuming side of technology.
So that interview was a little bit unexpected.

Both Elon Musk and the interviewer - Mohammed Al Gergawi (a Minister of Cabinet Affairs of the UAE) were a little bit nervous.
Al Gergawi mostly asked Musk his list of prepared questions (a pretty good list) and almost did not interrupt Musk. That resulted in a "psychologist session" for Musk: he drifted away from more generic questions (such as "why are you pushing the limits?") toward the topics he likes to tals about (how he made decision about building reusable rockets).

One time during interview Al Gergawi Musk and it added some embarrassment to both Musk and Gergawi:
Al Gergawi: Why it is dangerous? I mean there is two view; one view is the artificial intelligence to help humanity, there is another school of think or thought is artificial intelligence as a threat to humanity. Why is it?

Elon Musk:
Well, I think it's both. You know – it's like – one way to think of it is, imagine we're going to be visited – imagine you're very confident that we're going to be visited by super intelligent aliens in, let's say, 10 years or 20 years at the most - super intelligent.

Al Gergawi:
So you think within 20 years ...

Elon Musk: Yeah so.

Al Gergawi: ... we'll have alien in Earth?

Elon Musk: [Surprised] Ha-ha. [Switching to a serious tone] Well, digital super intelligence will be like an alien.

Al Gergawi: It will be like an alien?

Elon Musk: Yeah.

Al Gergawi: But my question is: "do you think there is either intelligent life outside there"?

Elon Musk: It seems probable, but I think this is one of the great questions in physics and philosophy is where are the aliens; maybe they're among us, I don't know. Some people think I'm an alien. [Applause]
Not true. Not true.

No matter how much feminism pretends otherwise, women are not keen to form lasting relationships with unemployed men.
The reality on the ground is that many women consider extended unemployment a good-enough reason to end a marriage.
A cynical but not unrealistic view is that humans tend to display loyalty to performed roles in relationships, not to individuals.
If one individual stops performing their assigned role, the relationship ends.

Meet Matt:
1) Advanced Artificial Intelligence researcher.
See French Wikipedia page.
2) Created the best data compression algorithm for 7-Zip (and made a small fortune in the process).
3) Smart.
4) Open.
5) Honest.
6) In a great physical shape:

- Does Yoga:

- Runs marathons and super-marathons:

7) Social and nice to people.

You may assume that Matt is so good that he has no problem with having a satisfying love life.

But that is not the case.

Matt is 61 and so far he had two love relationships:
1) At 37 [sic!] Matt met and eventually married Joan.
Joan was much older than Matt, was verbally abusive and refused sex for the last several years of their relationship - until her death from a stroke.

2) For the last 5 months Matt dated Karen and describes that relationship as the happiest of my life

Karen left Matt (and Florida) for her daughter in Maine.

I was socially inept until my 20's and single until I met Joan at 37. We had an emotionally abusive marriage for 22 years before she died 3 years ago. We fought and yelled all the time until the neighbors would call the police. She was depressed, held resentments, and was never happy, which is a common problem among sober alcoholics from alcoholic families. She also had PTSD and nightmares and became extremely racist after a black man broke into her home and raped her years before we met. She hated people, especially men, especially all my friends and family, and most especially me. When my mother would send me a birthday card, she would get the mail first, write vile obscenities on the envelope and send it back before I saw it. She would walk up to fat people, complete strangers, and tell them they were fat and they should die. Maybe it was her insecurity about her fitness. She was very goal oriented, got a Ph.D. in psychology, set perimeter bicycling world records (24 countries), indoor rowing records (33M meters), and completed Ironman 3 times. I saw her 5K times go from 21 minutes to over an hour as her health deteriorated before she died at 76. Maybe she hoped that people would like her for her accomplishments but it doesn't work that way. She refused to let me have time with friends. She would get enraged if I wanted to go to a fun run or if I didn't leave a race immediately after she got her award. She refused sex with me for the last several years of her life. When she died I should have grieved, but it felt more like I was let out of prison.

I don't know why I didn't leave her. I was always mystified when I would read about women that stayed with abusive men, but now I realize it works both ways. I don't like being single, but dating scares the shit out of me. On the list of things I want to do, dating ranks between hiring a lawyer and cancer surgery. I don't know why women think it is easy for men to meet women to date.

But I tried anyway. Karen was the first to show any interest in me after being single for over 2 years. Our time together was wonderful. She likes my friends and I like hers. If I ever did anything to piss her off, she would let me know right away and we would resolve it, instead of holding a resentment and bringing it up years later. I can trust her completely, something that Joan never did for me because so many other people had let her down in her drinking days. I still love Karen and I keep hoping she will change her mind and come back. But if she doesn't I will have to accept it and move on.

That story is quite impressive and made me think.
Here is my analysis:
1) It is not enough to be a perfect man in order to have a good love relationship.
You have to actually find a good match.
2) In order to find a match you have to put an effort into matchmaking:
- Think about how and where to find the right person.
- Put time and effort into actual search.
- Convince that person to stay with you.
- Train yourself to handle rejection (not everyone who you consider a good match would consider yourself a good match, but until you ask - you may not know).
3) That lesson can be applied not only to romantic relationships, but to all other relationships: work, (jobs and business), hobbies and friendship.

What do you think: is ability to make new relationships an important skill?

Letterman: But you are worth like 4 billion dollars or something?
Trump: I hope so.
Trump: We are living in very precarious times. If you look at what certain countries are doing to this country, such as Japan. I mean, they've totally taken advantage of the country. ...

Trump did not change.

Back then he was vague about his wealth he is vague about his wealth now.

Back then he was blaming other countries (Japan) for taking advantage of the US. Now he is blaming other countries (China and Mexico) for taking advantage of the US.

More Trump history.

A recruiter told me that when he interviews candidates - he asks them their salary history.
Not just what candidate is making now, but what candidate has been making on his previous positions too.

There are two main reasons why he asks salary information:
1) Make sure that hiring company is able to pay what candidate was making.
2) Check consistency of candidate's story (does claimed salary look similar to the typical compensation for the position like that?).

I asked him: "Do you give that salary history information to the hiring manager?"
He said: "No. There is no need to pass that information to the hiring manager".

I asked: "If candidate had salary that is significantly lower than current position pays - do you reduce the salary that company offers?"
He said: "No. Company already has compensation defined for that position."

I asked: "How many candidates agree to share salary history information?"
He said: "Almost all candidates talk about their past salaries."

That openness is a little bit surprising.
I myself, in the past, did not share my salary information with recruiters (but I shared how much I want to make at the new position).

Do you share your salary history when you talk with recruiters?

API's of some of our business partners are down today, thanks to Amazon S3 being down in their North Virginia data center.

Amazon's failure is the hottest topic on Hacker News today with 1500+ upvotes after just couple of hours:

Admins joke about Amazon uptime status panel that falsely report "green" simply because it relies on failed S3 service:

The ease with which AWS was able to get off the ground by leasing colocation space in northern Virginia in 2006 is the same reason that US-East is the most fragile molecule of the AWS cloud: it’s old, and it’s running on old equipment in old buildings.

Fortunately, when I chose datacenter for Amazon SES - I picked Amazon's "West" datacenter. It is up.
I expected Amazon's primary (North Virginia) datacenter to fail again. Today I got the confirmation.

PostJobFree itself is hosted on SoftLayer - that never had any major downtime like Amazon has every few years.
