The first thing you could order online was pizza from a Pizza Hut branch in Santa Cruz.

I will post it here as a reminder to have my own way of coding 💻✨

Network switches

What’s a network switch ?

A switch is a device used in computer networks to connect multiple devices together within a single local area network (LAN). Its main role is to facilitate communication between different connected devices, such as computers, printers, servers, IP phones, etc.

It is a mini-computer which is made up of RAM, ROM, flash RAM, NVRAM, a microprocessor, connectivity ports and even an operating system.

RAM

RAM (Random Access Memory) contains the current configuration of the switch and temporarily stores the MAC address table, which is then processed by the microprocessor.

Microprocessor

The microprocessor is the heart of the switch, responsible for data processing, including switching and creating links between multiple devices.

External memories

External memories, such as flash RAM, ROM, and NVRAM (Non-Volatile RAM), store configuration files , different versions of the IOS , etc ...

Ports

The switch ports are the communication interfaces of the switch. There are several of them, generally 24 for a Cisco switch. Each port is associated with an LED which indicates its status and activity.

How does it work ?

Now how does a switch work to transfer information from one machine to another?

Suppose we have 4 machines: A, B, C and D connected to our switch in ports 1, 2, 3 and 4 as follows:

The switch only works with MAC addresses , so basically we have an empty MAC address table stored in RAM as soon as the switch starts up which looks like this : 

Transmitting data from machine A to machine B happens in the following steps:

Machine A sends a frame to machine B

Once this frame arrives at port 1 (which is the one linked to A), the switch reads the source MAC address and stores it in the MAC address table

The switch reads the destination MAC address and looks for it in the table, if it is not in the table, it broadcasts to all the active machines connected to the switch except the source one.

If the port linked to the machine we want is active, it sends a response frame from which the switch reads the MAC address we were looking for (@B)

Once done, it records the MAC address of B in the table.

This process repeats until the switch reaches what is called "MAC address table stability", that is to say it knows all the MAC addresses of the connected machines and has no more need to broadcast.

Starting and configuring a switch

When it comes to booting a switch, the process is similar to that of a traditional computer system:

POST (Power-On Self Test): The switch performs proper functioning tests on all hardware.

Loading IOS (Internetwork Operating System): The switch operating system is loaded.

Loading the configuration. At this stage we have two cases:

Either the switch already has a startup configuration defined and stored in NVRAM

Either the switch is blank and it is up to us to define the startup configuration when it goes to setup mode

Switch configuration

The configuration of a switch is done through different modes, such as user mode, privileged mode and global configuration mode, which allows access to specific configuration modes, such as interface mode, routing mode, line mode, etc.

And to do all this of course you must first connect the switch with the machine via the console cable and open a terminal emulator

💡 It should be noted that the only machine that can configure the switch is the one connected to it by a console cable, the others are only hosts.

my psionic warriors (tumblrites) does anyone have advice / tools for someone who would like to learn to make synth music but doesn't have any strong music understanding

Websites to practice Front-End

(22/02/2023)

Today I wanted to share websites to practice your frontend skills.

Front-end is complicated for my head (ask me to solve an algorithm with structure while but not to center a div HUEHHUE).

BUT at the same time I love a well done and coded design/ui. That's why today I want to share resources to help you train

1- Front-End Practice

They have 3 levels, beginner, intermediate and advanced. There's no "answer" so you can't copy the code, it's just you trial and error until you get to the template (which really is a website that exists)

One thing I thought was really cool here was that it tells you what you're going to practice the most in the exercise, color palette and search features.

It's very interesting for a front-end not to be dependent on a tutorial, because from what I've seen in interviews, they ask you to make a layout and you won't be able to make one yourself if you don't learn to break down a single layout from the beginning and try and making mistakes until it's perfect.

2- DevChallenges

I find the projects not only beautiful visually but also interesting to practice. Here you already have the solutions that other people recommend, but again I think it's best for us to try and make mistakes until we get similar.And it also sorts the levels.

Here an example:

Cool huh? Well, I hope this helps someone who is looking for projects to practice with. We can invest a lot of time trying to make a layout, so having something ready I know helps a lot.

I wish you good studies and a great Wednesday, drink water.

I was working on the love in paradise animation and when I went to the website I was using to edit it, it kept giving me ERROR messages only to find out all my progress I had done for the past 3 days is just gone.

I was sad as it is that I have to start over and when I go to the home page after creating a new file I noticed that there’s text on the file telling me that after 3 days that file is going to expire, aka delete itself.

So now I’m sad x2

If anyone knows a good editing software, program, website, whatever that’s free, doesn’t limit how long a project is, and either doesn’t have a watermark or has a watermark that’s by the corner of the screen then please share! 🙏

My favourite underrated thing about Tumblr is the low contrast theme. As someone who gets chronic headaches and already spends too much time looking at a computer screen due to my job, this theme hits the sweet spot for me where it doesn't feel like my eyes are actively being destroyed. Like when I'm scrolling Tumblr compared to Reddit or something it's night and day

ok. i need to talk about ayrobot referring to himself as a virus?? it seems he willingly went along with whatever the federation did to them in order to infect aypierre and take control of him. it being for revenge is obvious. but does he have other goals and motivations?? what the hell is going on.
