boltzmannbrain··on Israel airport security stole my laptop
Agreed. Lesson learned.

As recommended elsewhere in these comments, I'll likely use Chromebook + https://www.paperspace.com/ in the future, and implement a travel policy for my team regarding what material can be taken where.

> They're looking for responses that appear delayed, evasive, made up

Exactly. AFIK I responded normally.

Not to mention someone actually doing something malicious with their computer probably wouldn't tell security they're a SW eng.

Thank you. It was an unfortunate learning lesson. Even if I do get my laptop back it won't be usable -- I have to assume they've gone through it and tampered somehow.

Wow they asked you to login? I have the Apple watch feature for auto-login, but took my watch off as soon as they grabbed my laptop.

Yes I went through several tiers of security as well, each with different organizations it seemed (airport, private, gov't).

Taxi. I've traveled to Israel a few times now and the extra questioning seems standard.

It was more of the rapid-fire "where did you stay? what did you do your previous trips to Israel?", but also asking where I got the computer from, what I use it for, why I brought it to Israel, if anyone else touched it, etc.

Never got my laptop back.

Yes this could have been worse, and is relatively minor compared to other mideast travel horror stories. Nonetheless I feel frustrated not only losing my computer and non-backed up materials, but because this occurs as I am helping an Israeli tech company by sharing my knowledge and expertise. There has been incredible outreach initiative in the AI research community as of late -- e.g., DL Indaba in Africa -- but this makes us feel unwanted. I will continue working with the Israeli startup, but from my office in SF.

Curbside security guard asked a couple basic questions ("How long were you in Israel? Where are you traveling to?"). The guard at the first security gate inside asked ~20 questions (4-8 is normal). I think answering that I'm a SW engineer to "What do you do for a living?" made her suspicious. I was then directed to a side security area where they searched my bags and discovered my laptop. A few guards then escorted me to a side room. Here there was one guard interrogating me on and off for ~2 hours. Just about any question I asked was met with "We can't tell you that." They confiscated my laptop b/c they had to "run more tests". I said several times I would wait for the tests, but they 'insisted' I leave. As soon as I was through security I went to Turkish airlines for help, but their immediate (read: scripted) response was "We do not deal with airport security."

> the average monthly rent for a one-bedroom apartment at an insane $3,447, according to a 2018 rent report by Adobo. The U.S. Census revealed in March, the median rent in San Francisco in 2016 was roughly over $1,600/month. These numbers are worrisome in a few ways: 1. The egregious rent amount that is required for somebody to live in the city today. 2. The jump in median rent in a mere two years. 3. The $1,600 median rent from 2016 also included rent-controlled apartments which indicates their rapid disappearance.

median != average

Fun example: In 1987 the average starting salary of University of North Carolina geography graduates was over $100,000. In 1986 Michael Jordan graduated.

boltzmannbrain··on Ask HN: Engineers from non-CS background, how did you pivot into ML/AI?
> study textbooks. Do exercises. Treat it like academic studying

This. Highly recommend Russel & Norvig [1] for high-level intuition and motivation. Then Bishop's "Pattern Recognition and Machine Learning" [2] and Koller's PGM book [3] for the fundamentals.

Avoid MOOCs, but there are useful lecture videos, e.g. Hugo Larochelle on belief propagation [4].

FWIW this is coming from a mechanical engineer by training, but self-taught programmer and AI researcher. I've been working in industry as an AI research engineer for ~6 years.

Then you won't be using Javascript anyways. Like you said, Python is the way to go: PyTorch, TF, PyMC3, scikit-learn, etc.

boltzmannbrain··on Depression, Self-Identity and Reality: Living in a Story Created by Facebook
I'm happier and healthier that these conversations are happening; I'm not alone.

Facebook is clearly problematic, and I've been suspicious of the negative effects of Instagram and Hinge (dating app). The former would make me jealous/depressed/frustrated as I compare myself to glimpses of my peers supposedly winning at life. The latter would make me less outgoing in real life, b/c somehow flipping through dating profiles satisfied an underlying desire to meet new people.

I highly recommend Johann Hari's work: "Lost Connections" book [1], Sam Harris and Ezra Klein podcast episodes [2, 3], TED talk [4].

boltzmannbrain··on Guide to scaling engineering organizations
Re "Don’t mistake productivity for engagement": The story is quite similar to my recent departure from a robotics startup. Even though the company had the suggested survey system in place, management made me feel like an engineering resource to be allocated rather than a person with career ambitions. The survey was one of several facades the CEO had in place.

boltzmannbrain··on Ask HN: Is neuroscience-inspired machine learning the next big thing?
There was a rather interesting talk at the Forbes Under 30 summit last month on this, "How The Brain is Inspiring AI" [1], but I cannot find the video. Lavin argued neuro and cognitive science -inspiration, not derivation, is useful at varying levels of abstraction, i.e. Marr's levels [2]. He showcased three works at the respective levels: Tenenbaum et al at MIT [3], some Vicarious research [4], and Blake Richards' work towards "DL with segregated dendrites" [5].

boltzmannbrain··on Ask HN: How to develop a HIPAA compliant app?
Thanks I'll definitely look into these! In your research and trialing did you compare TrueVault (mentioned in other comments). Digging around today I'm rather impressed, but haven't tried anything yet.

And if you don't mind, what do you consider a "sane price point"? I'm assuming that price is relatively small compared to the actual AWS hosting fees you pay on top of the PaaS, no?

boltzmannbrain··on Ask HN: How to develop a HIPAA compliant app?
Thanks for the TrueVault pointer, that's a great resource for info! I was going to followup asking your thoughts on using their service vs doing it yourself, but reading the dev guide posted by @jameslk I came across this:

    We think this comment from Hacker News sums up the technical debt required to roll your own HIPAA compliant infrastructure quite accurately. This was completely unsolicited and is not from a TrueVault customer.
    
        "[Building our own HIPAA compliant infrastructure] took upwards of 1,000 person-hours to figure out HIPAA-compliance issues. This will continue to be an ongoing cost for us, because HIPAA is an ongoing law and it changes sometimes. It takes substantial auditing time and money." — jph

Yeah, if it could keep a calendar, man that'd be dangerous.

a. Why use Go for robotics? What pros/cons are there compared to Python and C++?

b. Is Gobot intended to compete with ROS?
