The fundamental problem of #web #development:

Turning trees into tables and back

(Thread 1/6)
It may seem simple as you may have some data in tables (hello, MySQL) and you want them on a web page (hi, <table>). But you start joining data from other tables and you end up displaying a tree in a table. How? You never know how to do it until you try to use that. UX!

But if you have tree-data, tree-database (hello, Mongo), and tree components on website, you still need tables to present the data of similar structure. It's all 2D and are brains are trained to get information presented as combination of 2 axes. Hello, tables!

A petición de @ramloarc vamos a empezar a compartir más contenido #backend

Empezando con lo que trabajo en GitLab.

¿Cómo aprendí #rails #ruby ?

@ramloarc Si de verdad quieren entender el funcionamiento del MVC de Rails,

hagan una prueba creando una mountable app, que en #rails serian #railsengines

@ramloarc Hace 3 años, hice una prueba técnica básica,

Crear una API con #ruby #Rails y luego mostrar esos datos en un grafico de lineas.

LIMIT considered harmful in #PostgreSQL, a brief thread. 1/n
LIMIT can cause very strange planning issues in PostgreSQL, and you shouldn't use it unless it's definitely required. 2/n
(Of course, LIMIT *is* sometimes required, so use it if you need to!) 3/n

We can create the location and content of our page

Beginning a thread🧵 about the basics in #Python you need to know for #Django👇

Django is a #webframework to build interactive #websites for Python and is great for fast #development
1/ 19 Variables are used to store information, so that they can be used later on in your code.
In Python a ‘string’ is text and a ‘integer’ or ‘float’ is a number
‘car_brand’ and ‘brand_type’ are variables in the example below

Variables can be stored inside other variables
No special signs are allowed to be used in the name of variables, except for ‘_’ like.
Numbers are allowed in the name of a variable, but not at the start
So ‘1car’ is not OK and ‘car1’ is OK.

building a long-life (10yrs+) graph-backed web service for @pariyatti (a non-profit). we're planning to use #neo4j

i have some questions.
#python + #django support seems... weak, at best? (latest commits to `neomodel` and the django plugin are 2019/2018 with no support for neo4j 4.x)

is this a misconception on my part? i'd love a shout out from people happily building webapps with #neo4j on #python out there
#ruby and #rails support seems okay. #activegraph is a thing and there was a commit this week. the design seems sane.

i have 10-year-old rails apps, though. they... don't work. the ruby & rails ecosystem isn't really geared toward "boring things that will work in 10-20 years"

I know you have heard of password #Salts which are similar to Nonces and used to add uniqueness to passwords and protect against pre-computed hashes (rainbow tables).

Did you also know about password #Peppers ? They are equally important too.
In modern web applications of today, you should #Pepper your passwords as well as #Salt them too before hashing them. Here is the order:

Original Password ---> Salt ---> Pepper ---> Hash ---> Store-In-DB.

However, if you #Pepper passwords wrongly. It could be very disastrous!
What do i mean by this ?

Well, the simplest (and safest - very important) way to #Pepper a password is to HMAC(Original_Password, key) it.

HMACs are resistant to length-extension attacks & brutes-force attacks.

There must be a #Pepper key used for the HMAC too

1/ #Django will use watchman to do autoreload if it's installed since 2.2. The default reloader runs stat on all the files in your project once per second, whereas watchman will use os file system events, which is much more efficient.
2/ I never cared about this until I spent an afternoon figuring out why Docker for Mac's hyperkit process sits on 120% - 150% cpu use while running my mid sized django project in a container.
3/ i used 'docker stats' to deduce which container, then 'top' and 'ps auxf' to work out which python process was the problem. Then did a thread dump of the django server using faulthandler.dump_traceback() triggered from an API call, and then 'docker log'
