rb2k_··on Tech bosses are globalists, not libertarians
> Sam Altman runs YC now and as of last year was apparently seriously considering running for governor of California. That strikes me as grandiose and not good for society

Arnold Schwarzenegger was the Governor of California. At least as far as the 'what makes him qualified' thing goes, apparently that's not a real concern for voters :)

rb2k_··on Rapid release at massive scale
Keep in mind that the quarterly earnings report was 9.32 billion USD. That is approximately 100 million a day. I'd say downtime at that scale is important.

Also: People tend to call the police: http://time.com/3071049/facebook-down-police/

rb2k_··on Rapid release at massive scale
Facebook has a "dead code society" t-shirt for these kind of single commit delete numbers as well :)
rb2k_··on Why Germans pay cash for almost everything
I moved from Stuttgart to the US 5 years ago. I am always delighted to come back and see that I need less and less cash. It blew my mind when even Aldi and Lidl jumped on the credit card train.

Looking forward to the day when I can visit Germany without having to go to the ATM.

rb2k_··on “We will stop updating and distributing the Flash Player at the end of 2020”
From what I recall there were quite a few, most of them discontinued: https://en.wikipedia.org/wiki/Adobe_Wallaby https://en.wikipedia.org/wiki/Shumway_(software) https://en.wikipedia.org/wiki/Google_Swiffy

There's also https://github.com/tobytailor/gordon/wiki

I guess most of them are more or less dead :-/

rb2k_··on Google launches Hire, a new service for helping businesses recruit
LinkedIn has a PDF export and I see plenty of exported LinkedIn profiles when doing candidate interviews.

Seems to work for a lot of people.

rb2k_··on The capital sharp S in now part of the official German orthography
There are tons according to http://www.wordmine.info/Search.aspx?slang=de&stype=words-wi...

FRAKTIONSZWANG FREIHANDELSZONE KONFISZIEREN [...]

A lot of them are combined, but still quite a few 'regular' ones

> Even our Google Wifi access points don't support IPv6 in their latest firmware

They actually rolled IPv6 support out with their latest firmware.

I'm at sea at the moment, so I can only find the play store note: https://play.google.com/store/apps/details?id=com.google.and...

"WHAT'S NEW

IPv6: Enable IPv6 on your Google Wifi."

rb2k_··on Building a NAS
I recently built a NAS with 4x 4TB 2.5 inch drives
rb2k_··on The Utter Uselessness of Job Interviews
Having done interviews at a few of time, I'd say that's mostly false, at least for the last 2-3 years.

As far as I can tell, there's always a pre-defined pool of questions. Some of them are pretty 'open ended', but still targeted towards getting a good impression of a certain area of knowledge.

That being said, I had an interview with Google at some point in the past where one of the interviewers almost seemed appalled that I didn't know the exact list of items that can be found in a filesystem superblock. But at all other companies it seemed a bit more sane. I guess it's partially a function of the type of personalities a company is willing to hire :)

rb2k_··on The Utter Uselessness of Job Interviews
It should probably have been titled "The Utter Uslessness of Unstructured Job Interviews", because that's the kind of interview the author criticizes.

In my personal experience, structured interviews can be very helpful in determining a candidates abilities.

rb2k_··on USCIS Raids in SV – can anyone corroborate?
I would guess that those are the 'normal' site visits for H1Bs that happen every now and then and somebody didn't understand what those are.

I know several people that had them over the last few years. Standard procedure to make sure you're actually working where they say you are.

As far as the tweet goes: There is literally no first (or possibly even 2nd) hand evidence at all so far.

rb2k_··on How We Are Improving Performance
Since the post mentions performance as one of the main problems, it seems kinda strange to defend the Mac Pro.

The trashcan Mac Pro has very outdated Xeon E5620 CPUs and it doesn't seem like there's a lot of upgrades in the pipeline. I can even see Apple stopping the sale of these in favor of iMacs.

I think any 'regular' sever with e.g. an Intel Xeon E5-1650 v3 be about twice as fast for basically the same price.

I'd assume that image manipulation is mainly a CPU bound issue.

> Racking servers, even if they're cylindrical, is actually much easier than building an entire real-time image rendering pipeline from scratch.

Scaling a service based on Mac Pros is probably much harder than starting to port pieces of a real-time image rendering pipeline to hardware that is a lot faster and more readily available. To be honest, for the price of the Mac Pros, you can probably run a lot of CPU hours in AWS / ... and skip the whole rack-n-stack.

That being said, I'm not the one running an image rendering business, so I'm just armchair quarterbacking :)

rb2k_··on How We Are Improving Performance
Ha, I thought that was a joke.

Apparently not: https://blog.imgix.com/2015/05/08/racking-mac-pros-hardware-...

rb2k_··on Three Women Blinded by Unproven Stem Cell Treatments
Oh, super interesting.

My mother has macular degeneration and the only thing they even said was possible so far is injections with Eylea, Lucentis or Macugen.

I guess she manages currently, but it's interesting to see that there are other options

rb2k_··on Three Women Blinded by Unproven Stem Cell Treatments
They had macular degeneration which usually can be slowed down or stopped while there's a bit of vision left. Now they're at "no light perception". Considerably worse.
rb2k_··on Facebook’s code quality problem (2015)
That is usually how all companies at that scale release code (at least the ones that I know of).

Only that it's not 365 groups, because at the size of FB that would be several million people.

rb2k_··on Study: Immigrants Founded 51% of U.S. Billion-Dollar Startups
> One of the basic premises of anti-immigrant policies is that you can somehow influence the ratio of "useful" vs "not-useful" immigrants.

I think there is a very strong correlation to 'documented' vs 'undocumented'.

"Science vs" had a great episode on immigration that talks specifically about the difference in these groups: https://gimletmedia.com/episode/immigration/

rb2k_··on USCIS Will Temporarily Suspend Premium Processing for All H-1B Petitions
You pay money, they process it in 2-3 weeks or you get your money back.
rb2k_··on Ask HN: Are people lying about their salaries?
Usually everyone achieves 100% of the bonus. Good performers more than that.

It's not part of the 'base', but it's almost a certainty that you'll get it.

rb2k_··on Ask HN: Are people lying about their salaries?
At least with the 'big' valley companies, as a "senior engineer" (level 5) the usual numbers are around $170k base + a bonus that is 10%-20% of your base salary.

That's about $200k cash without RSUs.

So I'd say people are not lying.

I guess if you switched 7 times in 10 years, it's hard to get RSU refreshers / salary bumps and companies tend to, if in doubt, hire BELOW your actual level.

rb2k_··on Why I Don’t Talk to Google Recruiters
At Facebook you can usually chose which team you will join after bootcamp, so asking to be interviewed by your future manager is a bit of a problem.
rb2k_··on The open-office trend is destroying the workplace (2014)
I doubt anyone actually correctly measured this without giant amounts of residual confounding. (As usual with most social sciences)

That being said: I am having a better time compared to sitting in a 1-2 person office room. So for me it's a win :)

rb2k_··on The open-office trend is destroying the workplace (2014)
Lots of people. There are some cozies (Think 4 thick curtains and a few sofas inside) or walls with meetings rooms between every 4-5 rows of desks.

Also: nobody really takes calls from their desk. If you want to do a VC call, you get a conference/interview room. Same for long-winded discussions or whiteboard sessions. You start conversations in the common area, but if it's a larger undertaking people might move into a designated space.

rb2k_··on The open-office trend is destroying the workplace (2014)
I seem to be the odd one out in that I actually enjoy an open office setup.

I've had both and I feel there's so much more collaboration happening in an open office. I almost see it weekly that there's a LOT of learning through osmosis, listening in to conversations, ...

I guess I have a pretty easy time keeping up concentration/flow. So in this case, it "works on my machine" :)

rb2k_··on “Health benefits” of moderate drinking disappear when controlling for wealth
I'm afraid not, my knowledge is all 2nd hand (wife is scientist) :)
rb2k_··on “Health benefits” of moderate drinking disappear when controlling for wealth
Isn't Mendelian Randomization prone to pleiotropy? I've never understood how people can control for that without a complete understanding of the genome.

I wonder how much of that can be compressed for transfer and storage.
