Today: Have you ever looked at the semantics of "round" in your programming language. Look at JavaScript and Python for example.

The biggest unsolved problems of applied computer science:
* floating point numbers
* date/time
* text

Just found some interesting code in jemalloc's implementation of a mutex:

if (ncpus == 1) {
goto label_spin_done;
}

https://github.com/jemalloc/jemalloc/blob/1df9dd35154ca460facbd74f779a13dcece78dac/src/mutex.c#L51-L53

Microsoft just open sourced their STL implementation! https://devblogs.microsoft.com/cppblog/open-sourcing-msvcs-stl/

I quite like the idea of the new operator, although I think it looks ugly.

I published my first rust library: https://crates.io/crates/adjacent-pair-iterator

#/usr/bin/env bash
for string in 1{,+,-}2{,+,-}3{,+,-}4{,+,-}5{,+,-}6{,+,-}7{,+,-}8{,+,-}9; do
result=$(($string))
if [[ $result == 100 ]]; then
echo $string
fi
done

Then I came up with a solution in #bash that took me ~5 minutes to write but with an execution time of 20s.

123+45-67+8-9
123+4-5+67-89
123-45-67+89
123-4-5-6-7+8-9
12+3+4+5-6-7+89
12+3-4+5+67+8+9
12-3-4+5-6+7+89
1+23-4+56+7+8+9
1+23-4+5+6+78-9
1+2+34-5+67-8+9
1+2+3-4+5+6+78+9

At first I came up with a solution in JavaScript.
time spent: 22min
execution time: ~170ms

At todays C++ meetup I was told a programming quiz:

Given the digits 1-9 (in that order), you can combine them with either '+', '-' or nothing.
Now find all of these mathematical terms, that evaluate to 100.

You can use any programming language and library you like and you have 1 hour to complete the task.

Interesting. I just found out that ldd is a shell script.

I just found out that a.out is not actually a.out but ELF. I feel tricked.

This looks like it's worthwile supporting: https://www.kickstarter.com/projects/alecaddd/akira-the-linux-design-tool?ref=discovery&term=akira #design #linux

In the meantime: Why not help me with finding better wordlists (less obscene and garbage words) for https://fsmaxb.github.io/correcthorsebatterystaple

What I was wondering recently: If people are so bad at thinking up good passwords, why not just generate good ones for them and display them as possible candidate? (But definitely not send them via email).
