Flask pretty-prints response generated by the flask.json.jsonify function. Avoiding this on a per request basis doesn't seem to be intended: There is a configuration variable for the whole application: JSONIFY_PRETTYPRINT_REGULAR. But setting that to False minifies every JSON responses. And, in general, I enjoyed the pretty printed output. So implementing X-PrettyPrint - which seems to be a quasi-standard - also sounded like a the wrong way because it means replacing the call to jsonify by a custom implementation. This short story has a happy end though: Flask does not pretty-print the response if it receives an AJAX request. So one can just send the appropriate header:
curl -H 'X-Requested-With: XMLHttpRequest' "https://exmaple.com/api/endpoint.json";

I installed a pfSense firewall behind my Fritz!Box Router, that does several jobs like VPN, Adblocking, etc. What always bothered me was, that this firewall could be easily bypassed by Wireless clients, because I am using my Fritz!Box as a wireless AP and therefore not physically isolated from the Internet connection. One could just set the Fritz!Box IP as the default gateway and bypass pfSense. If you have ssh access to your Fritz!Box you can fix this! Would you like to know how?

For some reason, [Jira]'s [formatting] is not Markdown. Since you write everything in Markdown, you might be looking for a converter. If you furthermore hate node.js as much as yours truly, the search can easily claim your soul. Rest assured - I think [mistletoe] is the answer we are seeking. It is a pure Python Markdown parser which can render the parsed Markdown in any format, and one of them is Jira. It even comes with a [script] for this exact purpose.

I am writing a backup script which is supposed to backup data to a remote server, encrypted, and run as a scheduled task on a Windows machine. If you want all of that, you will have to store the encryption key somewhere. Instead of storing the password in plaintext, I had the idea to use the [Data Protection API]. Initially worried that I might have to write a wrapper for [CryptProtectData] myself, I quickly found the decent looking github project [DPAPIbridge]. Ultimately however, I figured out that Powershell can do all things. Presenting vault.ps1:
  [string] $StoreSecret,
  [string] $filename )
[void] [Reflection.Assembly]::LoadWithPartialName("System.Security")
$scope = [System.Security.Cryptography.DataProtectionScope]::CurrentUser
if ($StoreSecret -eq "") {
  $data = Get-Content $filename
  $ciphertext = [System.Convert]::FromBase64String($data)
  $plaintext = [System.Security.Cryptography.ProtectedData]::Unprotect(
    $ciphertext, $null, $scope )
} else {
  $plaintext = [System.Text.UTF8Encoding]::UTF8.GetBytes($StoreSecret)
  $ciphertext = [System.Security.Cryptography.ProtectedData]::Protect(
    $plaintext, $null, $scope )  
  [System.Convert]::ToBase64String($ciphertext) > $filename
This script can be run as vault.ps1 [-StoreSecret SECRET] FILE. If the optional argument is present, it will store a protected blob containing SECRET in FILE, otherwise it will read a blob of protected data from FILE and print the enclosed secret string.

I am quite unsatisfied with the current state of full disk encryption solutions available for use with Windows 10 on a Laptop with SSD. This blag post will mirror some of what [Bruce Schneier already said on the matter][Schneier2]: I will discuss some of the options and point out problems. I am not offering a solution, just a variety of bad choices to pick from. [Schneier2]: https://www.schneier.com/blog/archives/2015/06/encrypting_wind.html Do you want to know more?

So you develop in [Microsoft Visual Studio Community Edition](https://www.visualstudio.com/de/vs/community/) and you long for the old days when there was a way to get the [MSDN Library](https://msdn.microsoft.com/en-us/library/) as an offline help file? Fear not, you still can. Open Visual Studio, type Ctrl+Q to open the quick access bar, usually located in the upper right corner of your interface. Enter Help Viewer, it should yield one result by that name, marked as an *"individual component"*. Selecting that entry should allow you to download and install the Help Viewer. Now relaunch Visual Studio and start the Help Viewer via quick access in the same way. You will be prompted whether you want to download some *content* - and I bet you do.

I am not very disciplined. So trying not to be distracted while working at my computer is a major project for me. Since "deep work" is en vogue, it is possible to disable notifications in nearly every app nowadays. But there are often tiny bits one cannot change: Slack's icon in the notification area is one of those things: Whenever you have an unread message in any of the channels you are part of, Slack will show a small blue dot on its icon in the notification area. One can argue that it is not that hard to ignore that but fishing is also not that hard and I cannot do it. What I can do though is overwrite slack-taskbar-unread.png by slack-taskbar-rest.png in %APPDATA%\Local\slack\app-VERSION\resources\app.asar.unpacked\src\static\.

Spoiler: My main point in this post is not given away by the title. But first things first: What are all those words? Would you like to know more?

Part of me wants to write about all the [horror](https://www.bleepingcomputer.com/news/security/ten-malicious-libraries-found-on-pypi-python-package-index/) and [glory](https://crates.io) there is to be seen in package management, but quite frankly it'll take too long. Instead, I will just leave you with a tiny piece of advice. Here comes. If you are on Windows and you want to install a *legitimate* Python package[1], which in reality is a bottomless pit, at the center of which there is a C library, straight from hell - then maybe get the [Microsoft Compiler for Python](http://www.microsoft.com/en-us/download/details.aspx?id=44266) instead of, who knows, wasting hours or even days looking for a less reasonable solution. Credit, as so very often, [goes to stackoverflow](https://stackoverflow.com/a/27327236/1578458).
  1. like for example [PyCryptodome](https://pypi.python.org/pypi/pycryptodome), because naturally you are **fully aware** that [PyCrypto is dead](https://github.com/dlitz/pycrypto/issues/173). [back]

I am currently on vacation and my Hotel offers free WiFi in the lobby. The reception on the third floor, where my room is, is pretty bad on my Thinkpad and my phone doesn't receive anything at all. Fortunately, I am always carrying a high gain USB WiFi stick with me that gave me almost optimal signal strength. Having 2 network cards[1] I was able to use my Windows 8.1 machine as a Wireless Repeater (more…)

On 2016-08-01 a law came into force, allowing customers in Germany to use any internet router they want, as long as it meets the providers requirements. On that day I decided to buy a Fritz!Box 6490, for three reasons: 1. I wanted to replace the crappy router my provider gave me (which didn't even have WiFi) 2. besides its routing function, it is able to stream up to 4 concurrent TV programs into the Network 3. it was the only device that fulfilled the above-mentioned requirements. I wanted to setup [Tvheadend](https://tvheadend.org/) to act as an intermediate between clients and the router, because it would allow me to have an EPG, stream the same program to 2 clients, while only occupying a single stream of the Fritz!Box, and allow me to record TV shows. As you can see from the date of this post, it took me one year to figure out how to do it.

This blag post describes how to use a [Raspberry Pi](http://amzn.to/2wjICvo) to remotely "press" and potentially "hold" the power button on a PC. This is my first non-trivial (still pretty-trivial) hardware-related project. So don't expect anything too fancy. Would you like to know more?

I have a [problem with my Nokia 3](https://android.stackexchange.com/q/180669/197410) and decided to try the [Nokia customer support](https://www.nokia.com/en_int/phones/support) while doing some [recreational math](https://projecteuler.net/), that's what a great Saturday is to me. Don't judge. During the conversation, I grew very suspicious that I was talking to a chat bot. This was the first time for me hearing about chat robots being deployed in support by a [respectable company like Nokia](https://en.wikipedia.org/wiki/Nokia#Controversies), so I decided to make sure I wasn't being paranoid. Time for a Turing test! I guess you can never really know, but I am quite convinced they lie to me and are actually robots. You can try it yourself, just go to [their support site](https://www.nokia.com/en_int/phones/support) and start a chat. Would you like to know more?
