Intellij idea source code navigation

• ` to navigate to last edited location

… though most of this is helpfully configurable in ideavim; esp: map <leader>b :action GotoDeclaration<CR>¹ for “go to declaration”, which is <Alt+B> in vanilla ideavim. I should track things I use my mouse for most often and replace them with ideavim shortcuts.

Lenovo Thinkpad disable Fn key

Nice that I don’t have to use BIOS for this. <Fn+Esc> disables Fn key functionality.

Random / books / to read

• Black on Red: My 44 Years Inside the Soviet Union: An Autobiography by Robert Robinson | Goodreads - recommended by A.

I read Black On Red: My 44 Years Inside The Soviet Union, a book by Robert Robinson, An African-American who lived in Detroit during the Depression. I had to read it again, for it is about as gripping an autobiography as one can find.

• Russian political jokes - Wikipedia

Mediawiki change allowed filetypes

• Avunculicide is the act of killing an uncle. First heard on Brooklyn 99, S5:E3

Intellij idea run class with cursor

The small “play” symbols to the left on some classes can be run w/ <C-S-F10> if cursor is on them currently.

Java supports labels!

Java label? Outer, middle, inner - Stack Overflow

someLabel:
    for (i = 0; i < 100; i++) {
        for (j = 0; j < 100; j++) {
            if (i % 20 == 0) {
                break someLabel;
            }
        }
    }

Used to tell break/continue.. which loop to act on.

Random / style / writing

Calling your example classes as something that might be interpreted as a keyword of the language you are writing a tutorial about is a bad idea. (Outer here: Java Nested Classes)

Java collections

Java Collections Tutorial is a really nice tutorial by the author of the other java really nice tutorial I’ve been following.

Python do something based on probability

python - True or false output based on a probability - Stack Overflow mentions a really neat idea:

def decision(probability):
    return random.random() < probability

timew

TODO finally read the man page and learn to use it right, esp. splitting; look at history for the usual things I do manually (esp. moving back starting time)

In my daily file, I need a better vim shortcut not to move lines to the very bottom, but to the beginning of the following day (===), should be easy - TODO

Intellij idea breakpoints with no executable code

So here’s a nice difference w/ Python - in Python, you can set breakpoints everywhere, and you can add something random after the line you want to look at if it’s the last line of the function. In java, I assume some pointless lines are optimized away or considered uninteresting, but you can set a breakpoint to the } bracket and the end of the function if it’s on a line alone.

(Have yet to find a way to nicely output multiple values in the debugger though.)

Intellij idea “Execute code” during debugging

What I could do in Python with 2, 3, 'test', function() I can do in Java by returning an array or whatever, with

Object[] t = {1, 3, 5, "whatever"}

Which is nicely covered by this Live template:

Object[] t = {
    $END$
}

that I run via exe<Tab>

Python

Did a lot of python, pandas, jupyter and enjoyed it so much that did not write any of the things I learned here, now they are lost forever. :‘C

Sonderurlaub / Germany / Bureaucracy

TODO update ym qutebrowser keybinding to remove stuff starting with … #:~: maybe?

Jupyter Notebook vim plugin copypaste

Things that I selected with vim keybindings can be copypasted with usual qutebrowser keybindings (or mouse).

Libreoffice calc search by regex

You can do it if you go in the find-and-replace dialog. Checkbox -> search all

Inverse regex

.. is surprisingly hard and implementation-dependant. You can always iterate and look for the not-matched things. [^aeo] doesn’t really work for capturing groups.

Random / TODO / Linux

I should really rewrite my timer function to be a) Python, b) better than the current version.

# Timer in zsh
tm() {
    local DATE=$(date +'%H:%M:%S %d/%m')
    local N="$1"; shift
  (utimer -c > ~/s/sounds/outbash $N && mpg123 -q ~/s/sounds/tib.mp3  &
      zenity --info --title="Time's Up" --text="${*:-BING} \n\n $DATE")
}

utimer seeing minutes as m while everyone else (timew especially) wanting minutes as min makes me crazy.

Intellij idea

I can remove the tree of files by doubleclicking the tabs!

Intellij idea debugging paste

<Ctrl-Shift-V> gives a nice choice of things to paste, first thing being the current content of the buffer. The others I assume are historical.
