In the older Python implementation( by wessie)

`ALPHABET = "bcdfghjklmnpqrstvwxyz0123456789BCDFGHJKLMNPQRSTVWXYZ"`
is wrong `a` and `A` seem missing.

I find that is you use function in your code this helps alot to help in debugging your code
export PS4='+(${BASH_SOURCE}:${LINENO}): ${FUNCNAME[0]:+${FUNCNAME[0]}(): }'

This will print the the function name and the line number of the the script.
This really helps if you use lots of functions in your code

Re: Convert anything to Tree Structures in PHP

php has this stuff since 5.3 which can be used in similar way:
$tree = new RecursiveTreeIterator(new RecursiveDirectoryIterator(__DIR__, RecursiveDirectoryIterator::SKIP_DOTS));
Good job anyway

I would like to know if after using the new MacBook Pro 14"/16" with M1 Pro/Max if still think the same about Linux.
I'm software engineer in c/c++ and my dev boxes are Linux but it's becoming to be enough to me trying an extra effort to things that should be just work on Linux like a clipboard!

This will break for strings containing accents or other combining marks.

Eg: y̅a becomes a̅y with this function.

Thank you! That's a great set of tips. The shortcuts are my biggest issue. I knew about Ctrl+ins etc. but it used to be possible to move the system-wide app shortcut key from Ctrl to Alt or Meta, and now I can't seem to do that anymore. If I could move it to Cmd/Meta it would free up Ctrl for the terminal. It's not just the terminal but also emacs keys that use Ctrl, so Ctrl+A is beginning of line but if Ctrl becomes the gui shortcut key then Ctrl+A becomes select-all.

This one works for me.

function string_reverse ($string) { /// Multibyte String Reverse return \implode (null, \array_reverse (\preg_split ('//u', $string, null, PREG_SPLIT_NO_EMPTY))); }

__dir="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
__file="${__dir}/$(basename "${BASH_SOURCE[0]}")"
__base="$(basename ${__file} .sh)"

This code should be replaced with the following. These suggestions should run faster and don't involve spining up subshells for no reason. The usual way to write variable names is with majescule, not miniscule, characters. You might also try using ${0} in place of ${BASH_SOURCE[0]}. Lastly you will need to define or typeset your variables since you are using the "nounset" option.

__DIR="${BASH_SOURCE[0]%/*}"
__BASE="${BASH_SOURCE[0]##*/}"
__FILE="${BASH_SOURCE[0]}"

Re: Convert all Tables to InnoDB - Kevin van Zonneveld

Pieter Dings — Sat, 15 Feb 2020 22:08:33 -0000

Be careful using above ideas running them on a MariaDb Galera cluster. After some tables are converted the cluster stops working. Better to de-activate all running nodes. Only start the Galera bootstrap server, convert the tables. Restart the bootstrap server and add again the nodes one by one.

This way the MariaDb Galera cluster is having some time to get all databases/tables in sync again.

Enjoy converting. I tried it myself and it works awesome!

Thanks for the kind words and also for the suggestion! I hadn't heard of it yet to be honest, but perhaps this is an Ubuntu default as of Cosmic and what caused me to say it got significantly better afterwards (?)

Most of the issues you describe with copy paste has been solved for years... but there is a bug in 19.10 that causes issues with copy paste. It should be solved with the next update of Mutter.

Also by default you can copy paste to the terminal with ctrl+shift+c ctrl+shift+v. That, to me at least feels more easier then ctrl/shift+insert.

If you keyboard has ´ then you you can simply type ´e to write é.

Hope some of that helps.
