Hi, I'm Erwin, an SRE / software architect with a deep understanding of the entire stack down to the bare metal. Well, maybe not that, but pretty close anyway.

gnur··on Mysterious mutants: 13 masked people should have devastating diseases but don’t
One of the most difficult parts is both the desire (and possibly need) to gather more DNA from a pool as large as possible, with the option for re-contact for further investigation while also keeping that data safe and anonymous to prevent this being an incredible valuable target for both governments and corporations.
gnur··on Why the CIA won't waterboard, even if ordered by the president
War has never been cleaner then it is today, civilian casualties are down to levels never seen before.

While torture (and all other cruel punishments) have been common for many years, today it just isn't acceptable for many people anymore. Death is a better outlook then being tortured for days, weeks or even months without outlook at a future without being tortured.

War is the worst thing possible, but even wars have become less lethal and more "humane". The Geneva convention is not even 100 years old, before that plunder, rape and maiming and torturing where inseparable parts of war.

I hope most people don't "want" to go to war, but feel they are fighting a war for the greater good. Even isis isn't fighting a war because they want to have war, they are fighting for ideals and values. And the West is fighting for their ideals and values.

I can only recommend you to read "the better angels of our nature", it gives a much brighter picture of the future (and the present) then you seem to be experiencing.

gnur··on How big is the Google Earth database?
I've looked at the prices between 1980 and 2010, seemed to be getting about 1000 times cheaper every 10 years. And SSD pricing has gone down about 40% every year the last 4 years. Which would come to a price reduction of less, but some breakthrough is bound to be around the corner.
gnur··on How big is the Google Earth database?
Tt will take quite a while, 1TB aught to be enough for everyone.

Kidding aside, you can assume that in 10 years storage will be about 1000 times cheaper then it is now, so 3PB of storage would be around the cost of 3TB drive today, around 100$.

gnur··on Ask HN: Best ultrabook for Linux?
I have third gen X1 Carbon and I love it, I run openSuSE leap on it and I have never been more satisfied with a linux distro on a laptop.
gnur··on An administrator accidentally deleted the production database
But you really don't want to use those when working with databases, the performance loss is severe.
gnur··on Python 3 in 2016
I often dabble in other languages but in the end always return to python (3).

What it offers for me truly is the batteries included and easy, memorable and predictable syntax. (Probably due to experience).

Sure, Go is easier to deploy, Erlang and by extension Elixir are easier to scale.

But python does align very well with my personal though process. I don't think parallel and I don't have race conditions in my mind. If I want to quickly write something that will perform decently, I choose python, because the time I save by not having to learn a new language could be days or perhaps even weeks. I guess it boils down to this: with my current experience, I'm more then 10 times as productive in python as I would be in any other language.

Sure, it would be neat if I had as much experience in Erlang as I have in python, but that will take years, and at the end of the day, I'd rather finish my project this year with python, then next year with any other language.

gnur··on AWS Certificate Manager: Deploy SSL/TLS-Based Apps on AWS
The local client app is needed to verify that you actually own the domain. 3 month certs are actually more secure since there is shorter amount of time in which they can be stolen & used. The goal of letsencrypt is to make re-issuing certificates automated, so even a 1 week certificate is no problem since you can run a nightly cronjob to refresh it.
gnur··on OpenSSH: client bug CVE-2016-0777
It's from the linked page.
gnur··on Ask HN: What is your company's on-call rotation like?
Current rotation for me is: 1 out of 3 weeks from 7 am till 12 midnight as a systems administrator. Our SLA to customers is non-existent, so on-call duties are best-effort (if you are in the shower and it takes 30 minutes to respond, no real problem). Furthermore, this also means that it is up to the person on call to determine what needs to be done.

Outside of the regular work hours you are only expected to work when an alert / call comes in. If at all possible you should fix it, if it would take > 1 hour you start looking at temporary workarounds that will hold until you are back at the office. During regular work hours on-call tickets always get priority. When problems arise with external dependencies we open tickets in their support system and wait for their response. Most important in our case is to keep the support desk up to date so customers don't open too many tickets and to let people know we are working on it.

Depth of on call work depends. It usually consists of rebooting / restarting services and checking if they come up as expected and trying to find the root cause of the problems. If the root cause can be easily identified and fixed, fix it immediately. Otherwise, open a ticket to fix it asap.

gnur··on AWS Shell – An integrated shell for working with the AWS CLI
They could also be auto completed, it's not that hard, but it would be slow unless you cache it to some degree.
gnur··on Mars Rover Finds Changing Rocks, Surprising Scientists
Confirmation of existing discoveries perhaps?
gnur··on How I Store My 1's and 0′s (2012)
If you don't need speed, you could just use a few powered USB hubs and connect all your external disks to a raspberry pi (or perhaps something a bit faster like a minnowboard max).
gnur··on InfluxDB is now InfluxData, a platform for time series data
Why aren't you using telegraf?

(just curious, I've tried both collectd and telegraf and telegraf has been much easier to setup and control imho)

gnur··on Pokemon Go for iOS and Android
This really does sound awesome, I think I've played nearly every Pokemon title released for the gameboy, gbc, gba and nds. (after that I grew up a bit).

And I always missed a pokemon like title on my Android phone, if this game is the least bit like pokemon red it really could be awesome. I don't know if I'll be driving around town with the Pokemon Go Plus but I'm certain I'll find myself checking my phone more often while walking around and nearly having my pokemon on the desired level..

gnur··on Control your server using Whatsapp
Have you read the source of connectbot? Have you compiled the version you are using yourself? If not, the version of connectbot on the play store is no different then JuiceSSH.
gnur··on YouTube Red, a $9.99 Site-Wide Ad-Free Subscription with Play Music
You can use the youtube app on your phone, or the browser on your laptop, or the youtube app on your tv. So it isn't content that can only be consumed in the app on your phone.

Why not just use ssh?
gnur··on Myths about autism
Apparently, diagnoses of autism has become much more valuable for parents. (at least in the Netherlands). If you don't have a the label autism, you'll have to pay for everything yourself, but with a diagnosis the (local) government will help you out with certain things. (like schooling)

Something somewhat related, the diagnosis a child gets is highly dependent on the educational level of the mother. Higher educated mothers are more likely to have a child with Aspergers then "regular" autism. The cause is probably not genetic but more likely that a "smarter" mother will try to get a better (Aspergers) diagnosis then a mother with less intellect.

gnur··on New Chromecast 2015
But as long as new devices are coming out with micro usb the usb c cables won't become as common as micro usb cables.
gnur··on Why Is That Dog Looking at Me?
I can tell from experience that dogs also look at humans to get something they want that is not food.

When my 5 month old labrador rolls her ball under the couch (again), she tries for 5 seconds to get it herself, after that, she starts staring at me.

When she needs to "go", she will sit by the door and start staring at me.

Both of which are events that are not rewarded by food, but something she will enjoy by herself. (playing with a ball, and "relief"), even though in the latter case, I am very pleases she is going outside :).

gnur··on How much is Reddit making from Reddit gold?
I guess their servers need to be payed as well..
gnur··on “Two days ago the police came to me and wanted me to stop working on this”
Ship it on an usb drive. (use encryption)
gnur··on Raspberry Cloud – Dropbox for the Raspberry Pi
Not sure why this project is keen on calling itself Raspberry PI. There is nothing that makes this specific for the Raspberry, it's just a cursus based interface to Dropbox.
gnur··on Keystroke shortcuts in bash
I think it took me about 10 minutes to get used to it, it really is rather convenient. I still use <enter> very often when typing regular commands, but when I cycle through previous commands with ctrp+p/n it is much easier to hit ctrl+j.

Also, because my hands stay on the regular keys I don't have to look at my keyboard when switching betweeen typing commands and going through the history. It just feels more natural.

gnur··on Keystroke shortcuts in bash
I've increased my productivity recently by starting to use ctrl+p and ctrl+n for the previous and next command instead of the arrow keys, combined with ctrl+j for <enter> it has really made everything just a bit easier on the fingers.
gnur··on A Walk Around Chernobyl [video]
Did you also stop eating banana's?
gnur··on Ask HN: What are your favourite tools to work with?
vim
gnur··on Ask HN: Algorithms for text fingerprinting?
I've started a simular project myself recently, I check on various parameters (reading level score, words per sentence, syllables per word, sentences per paragraph, average word length, average syllable count) and calculate the distance between 2 texts / authors using a simple euclidean distance.

I started out with the code provided on https://github.com/mac389/ToxTweet/blob/master/textanalyzer.... I use it in a private project, but the results are promising!
