kinai··on Linux Sysadmin/DevOps Interview Questions
Isn't the biggest skill of a sysadmin to solve problems that he has not seen before? Learning all those answers to the questions wouldn't help you much in a real life scenario.

Instead of asking "what is/how do you do this?" it is better to give example scenarios and listen to what someone would do, to see how they approach the problem.

kinai··on What’s Inside a Black Hole?
Gravity is not a function of matter, and proving that curved space-time is real is trivial. So not sure where you are going with that idea...
kinai··on What’s Inside a Black Hole?
It is just wrong what they say, see my comment above for explanation.
kinai··on What’s Inside a Black Hole?
imo best for that: The Black Hole War by Leonard Susskind
kinai··on What’s Inside a Black Hole?
There is a misconception: Light cannot escape a black hole for gravitational reason (not to mention that gravity does not exist, it is a not a force, read up General Relativity). The real reason is that the space-time curvature does simply not provide a way for the light to go back. Same reason you can't go to the end of the universe if the universe would be a sphere.

Also if someone likes to talk about black holes it is good to remind people that it is not a hole...as the article mentions its a region, to be more precise it is a region in space-time that is cut off from ours. The whole issue is not just spacial but also temporal, that is usually the point when your brain gives up understanding the whole problem.

A good description would be: a black hole is the collection of events that do happen outside our space-time/universe. This also explains some of the paradoxes near the event horizon.

NoOps...how about no?
kinai··on Hiring Is Broken – My interview experience in the tech industry
Obviously one has to be smart about this attitude :) I am not saying acting arrogant/Idontcare will always be a good thing. Just the right amount of it so you don't come across as a scared little applicant.

But as I said earlier its usually bad to stand in silence with no answer and let time run out. Better to admit whats going on and try to explain what the issue is.

kinai··on Hiring Is Broken – My interview experience in the tech industry
Yea I once left during an interview when I realized that I don't want to work there anyway (the atmosphere told me).
kinai··on Hiring Is Broken – My interview experience in the tech industry
"I could feel my frustration rise as I am struggling to come up with a solution on a whiteboard....yep, I am definitely not going to pass this interview. I ran out of time before coming up with a working solution."

Instead of standing there with nothing its better to be straight up and just say "No idea mate" and then name reasons why that is but how you'd solve it in a normal situation. It is a lot about human psychology, showing them that they want/need you, not vice versa.

Sometimes all it takes is balls and a good amount of "I don't give a fuck" attitude.

I wouldn't let anyone treat me like Sahat got treated.

kinai··on Half Your Brain Stands Guard When Sleeping in a New Place
@hotelpeople A hotel is a safe environment and probably is usually associated with positive experiences. No wonder you sleep better there ;) I am the same
kinai··on Schools are helping police spy on kids’ social media activity
2016 Police Report: 4 kids were successfully stopped from stealing candy. Parents suing us because kids suffered psychological damage and now have a criminal record, but we all know that this is just caused by bad parenting.

kinai··on The World Is Getting Fatter and No One Knows How to Stop It
We had this as extra courses, Biology was another one, different.
kinai··on The World Is Getting Fatter and No One Knows How to Stop It
One of the big reasons: education.

I bet most here never had nutrition/sport theory in school, I did have that. If you know how your body works, how food is processed internally and what is good/bad fats/sugars/carbs then it is not hard to eat healthy. I don't do much sport and still don't gain. The rest is selfdiscipline

kinai··on Coursera and University of Illinois Launch MOOC-Based Data Science Masters Program
I wonder when there'll ever be requirement-free Degree Program...
kinai··on For anyone who has been turned down by 38 companies
I know what I said was a bit mean but its the truth, if you go the standard way like "writing application mail, send CV, witing for Interview 1 etc." then you are doing it wrong IMO. That is the way 1000 others go and then it's not surprise you are just one out of many who has to get lucky not to accidentially get sorted out by a shitty recruitment process. There are better/smarter ways to get a job, if you want to stand out you have to act differently.
kinai··on For anyone who has been turned down by 38 companies
"I got turned down by 38 companies, nobody wants to pay me 100k mimimimi" Murican Coders of the 21st Century at the biggest whiners ever...And honestly if you fail to get a job within 3-4 interviews then you are a) doing it wrong or b) applying for the wrong jobs.
kinai··on OLO – the $99 box that transforms any smartphone into a 3D printer
It's all cool but what for? I might have needed a 3D printer once in several years. Those who need it regularly for hobby buy a professional machine.
kinai··on Why I don't want stuff
I am in the same spot, but I got cloth for all climates with me, 1x65l and 1x45l backpacks. Also 3 pair of shoes and even 1 pair boots. ;)
kinai··on The blessing and curse of people who never forget
Regarding the hear: no, it is different stated before. For detail question: How to answer? I am not sure, we'd have to test it, but I can remember sometimes the smallest details, same goes for real life. I never paid any attention to how detailed my memory is in that regards
kinai··on The blessing and curse of people who never forget
Good question, I doubt that, mostly because the "audio" part of the movie is not like the video for me. I don't remember it as a stream. But I'd be curious enough to test that. I never thought about this much.

What often happens if that someone asks me if I have seen movie/series X and then I recall and fast forward through the video to remember the plot and characters. That must sound very weird/unrealistic but can't describe it better.

kinai··on The blessing and curse of people who never forget
Interesting, I listen to music all day, all types of genre, lot of classical pieces too, but I can't recall them like I can with video. But I am a very visual person in general, I also see what I think about, even words or numbers.
kinai··on The blessing and curse of people who never forget
I can rewatch every movie/series I have seen in my mind. I always thought that is normal until someone told me it is not. I can't even describe how it works, but basically I can see the movie and forward/rewind. Since I watch a huge amount of movies/series (1500+ movies alone) there is a lot in me head I guess. Can be fun though, if you are bored and got no tv/computer/phone around, I can close my eyes and watch something on demand :)

I also can remember most days in my life like this. As stated it can be a burden, those unhealed wounds of dramatic experiences that you live through over and over again in every detail.
