# Around mid November of 2018, Startpage.com updated it's visual look.
# Among other things, they changed the behaviour of the header block which
# contains the search bar and button. The header now follows you as you scroll. 
# I don't know what kind of idiot thought that was a good idea.

# To get rid of this behaviour add the following line into your uBlock "My Filters" list:

startpage.com##.header--content:style(position: relative !important)

Problem scenario: 
------------------
1) stupid Matlab installer wants to download several gigabytes into your /tmp directory.
2) You don't have "several gigabytes" available on your root partition (where /tmp is). The installer warns you and/or fails.
3) You DO have available disk space, but on some other disk/partition/wherever.


Solution:
----------
Run the command inside Linux filesystem namespace. For example:

MawKKe

#!/usr/bin/env python3

import sys
import os
import re
import subprocess as sub
import argparse
import tempfile
import json
from concurrent.futures import ThreadPoolExecutor, as_completed

MawKKe

#!/usr/bin/env sh

set -eu

PNAME="$(basename ${0})"

# OpenSSH default checksum type as of 2021-07
E=sha256

I ran into a stupid problem with C++ and googletest.

I set up a C++ project with CMake, and included googletest for writing tests. As usual, I created a library, and respecive test executable:

add_library(mylib mylib.cc)
...
add_executable(test-mylib test-mylib.cc)
...

target_link_libraries(test-mylib mylib gtest gtest_main)
