So useful

This is a tremendously useful website for vim users.
Lists plugins for vim.

Sometimes, I find the text so dense and difficult to read ( even when I think it is particularly well written ).

hello https://www.bortzmeyer.org/ --

Now I have this one bookmarklet installed.
By the way, that means bookmarklets work again !

Not much to say, is 2.6.x compliant

It took me some time to understand that sugar syntax.
First of : it's & :to_s obviously.
Operator is &.

What does it do ?

it turns

mythings.map(& :upcase)
# is the same as 
mythings.map(&:upcase)

into

mythings.map { |mything| mything.upcase }

Remark : sugar syntax can be a pain in the butt. I hope you do see it.

The map method applies the "block" { |mything| mything.upcase } on each and every elements of mythings and returns an enumerable of class mythings.class containing each result.

The operator is & and the argument in my example is :upcase. :upcase is a Symbol.
Symbols have a smart to_proc method.

Another example :

require 'date'
[1,DateTime.now,3].map(&:to_s)
# => ["1", "2021-09-05T12:06:54+02:00", "3"]

So how does it work ?

• &̀ when a parameter of a method is prepended with & then ruby knows this parameter to be a Proc

• :upcase is a symbol.

So the &:myproc is a smart shortcut implemented to turn the symbol :myproc into a proc.

Let's try it :

def call_my_block ( my_parameter, &myblock)
  myblock.call.myblock
end

The parameter &myblock is known to be a block.

When I use method call_my_block with the argument &:my_symbol :

• The second parameter is known to be a block.
• The argument will be translated into :my_symbol.to_proc
  If the first argument is of class KlassandKlassactually has a my_symbol method, then it will call it.

Example :

call_my_block DateTime.now , &:to_s translates into :

:to_s.to_proc.call DateTime.now 

note that :

a = :to_s.to_proc
#=> #<Proc:0x000055e77c191c98(&:to_s)>
a.call(13)
#=> "13"
a.class
#=> Proc

Hence :

call_my_block DateTime.now , &:to_s
# => "2021-09-05T12:06:00+02:00" 
[1,DateTime.now,3].map { |val| call_my_block(val,&:to_s) }
#=> ["1", "2021-09-05T12:21:54+02:00", "3"]
[1,DateTime.now,3].map(&:to_s)
["1", "2021-09-05T12:23:22+02:00", "3"]

Note ::

• A function/methods has parameters.
• When called the function is given arguments

In other terms, an argument is the value of a parameter.

Because copying data from one dynamodb to another dynamodb in another region is a pain in the butt even if you have a pretty small database.

Had to find a quick win. This tool has done the trick.

Impressive monitoring tool.
Raise alerts with complete configuration file to get informed through mail / etc

When they say "about no configuration", it is true.
It's a "tool" you take and use.

Just amazingly simple and pure efficiency.

Bravo.

Note : it will not help you understand what happened two weeks ago. It's not here to help you who did what three years ago, or what has happened last month with this or that. It 's a tool to monitor a platform health.

Because debugging is not necessarily about SQL FFS, and Ikeep forgetting how to remove the super verbose SQL output in rails console.

A must have seen about database indexing.

I just like this video so much.
What a great show and explain demonstration.

jq is a lightweight and flexible command-line JSON processor.

myjson.json :

[{"name":"JSON", "good":true}, {"name":"XML", "good":false}]

CLI :

echo myjson.json | jq .[1]

outputs :

{
  "name": "XML",
  "good": false
}

A must have : explains what the regexp is doing
A great tool to learn / design regexp.

Changes my everyday life.

Quick and great little JSON editor.
Works like a charm for my usage.
Mainly using it when not on my computer (ie when using a windows computer).

Unfortunately, not in everyone's bookmark... hence worth mentioning here.

Useful guide.
Marked for soon usage.

édifiant…

Et pendant ce temps, en France, on se dit que c’est une super bonne idée de faire des fichiers qui listent vos goûts, vos sports, vos hobbies, vos tendances politiques, vos potes, vos centres d’intérêt, vos tendances sexuelles, votre religion, etc. en sachant que le tout est très souvent fort mal renseigné.

Le problème, comme le dit très justement sebsauvage.net : ce n’est pas que vous ayez ou non quelque chose à cacher ou à vous reprocher, c’est que ça peut amener des tarés à vous cibler totalement arbitrairement. Ce sont les autres qui vous reprochent d'exister.
