Ruby on Rails, a menudo llamado simplemente Rails, es un marco de aplicación web escrito en Ruby. Fue creado por David Heinemeier Hansson y lanzado en 2004. Rails está diseñado para facilitar la programación de aplicaciones web al hacer suposiciones sobre lo que cada desarrollador necesita para comenzar. Permite a los desarrolladores escribir menos código y lograr más que muchos otros lenguajes y marcos.

Hello all! In this article, I outline my local docker setup for developing wordpress plugins and themes. I use docker to run local mysql (multiple versions) and php (multiple versions) as well as manage the wordpress installed plugins. Furthermore, I use the same setup for deploying to production, so it is particularly useful.
The majority of configuration resides in Dockerfile and docker-compose.yml, however, I also have a few scripts and naming formalisms that facilitate development and rational thinking.
Although we will not be using these screens, they have been made for a client in order to move a prototyping project forward.

Suppose you want to serve some paths with rails, and some other paths with wordpress. or you want the app to serve rails pages if they are available, and fall back on wordpress otherwise.
I've recently had to re-do this. This has happened too often for me, and it's just very annoying in general. There are many problems (and offered solutions) around /etc/hosts file, for chrome only as well as for the os x generally. I've noticed that the /etc/hosts file works just fine for curl, but does not work for chrome. This led me to believe that the problem was a chrome setting, but upon fixing it, I am less certain that Chrome is the culprit. My solution is below. Basically, the host file needs to be ASCII-compliant. I've had that file soft-linked and modified by a number of actors.
I run into this just now. The wrong way:
results = ActiveRecord::Base.connection.execute("select * from users limit 10")
The right way:
results = ActiveRecord::Base.connection.exec_query("select * from users limit 10")
Somehow the formet executes the query without returning a result. If you want to actually see the results of SELECT'ing something, use the latter query. (Which also means that you probably want to use the former for INSERT'ing, though I have not verified.)
The solution is to edit these lines in /etc/php/8.1/apache2/php.ini :
upload_max_filesize = 64M post_max_size = 64M memory_limit = 64M
The short answer is no. The box says, not compatible. Online on the HP website, you can download drivers that are supposedly for mac. But on my mac 12.5 Monterey, I was still unable to print from this multi-printer.
I was able to print from a windows laptop however, using the same printer. So to me it seems that the HP 520 really isn't compatible with macs.
