explaining modern brand names to a Victorian

me: so just like. a word, usually.

Victorian: a word related to the product, or-

me: no just a random word

Victorian: huh. because I'd have thought

me: yeah

Victorian: a word related to the product's alleged best qualities

me: no no it's just any word really. the founder might have some reason behind it, but it only makes sense to them most of the time

Victorian: interesting

me:

Victorian:

Victorian: but definitely misspelled right

me: oh EXTREMELY misspelled

🇺🇲 Dive into the history of the Apple III (styled as apple ///), a computer that marked an ambitious step forward for Apple Inc. Released in May 1980, the Apple III was designed to be a successor to the highly successful Apple II series, aimed at the business market.

💻 The Apple III was envisioned as a business-oriented machine that would bridge the gap between personal and professional computing. Apple sought to improve upon the Apple II's capabilities, both in terms of hardware and software, while maintaining backward compatibility. Steve Jobs, who was heavily involved in its design, emphasized aesthetics and functionality. The Apple III featured a sleek design and was intended to be more robust and reliable, with enhanced performance.

⚙️ The Apple III was powered by a 2 MHz Synertek 6502A processor, an improvement over the Apple II's 1 MHz processor. It came with 128 KB of RAM, expandable to 512 KB, which was a significant upgrade at the time. The computer featured an internal 140 KB 5.25-inch floppy disk drive. An external floppy drive could also be connected for additional storage. The Apple III supported a variety of display modes, including 24 lines of 80-column text and multiple graphics modes. It ran on Apple SOS (Sophisticated Operating System), which offered advanced features such as hierarchical file system and support for multiple users.

💡 The Apple III introduced several innovations, including a built-in clock, advanced sound capabilities, and a new keyboard design. However, it also faced significant challenges: The Apple III initially suffered from severe overheating problems due to the lack of a cooling fan. This led to hardware failures, with chips often becoming dislodged from their sockets. Early units were plagued by reliability issues, which hurt the computer’s reputation in the business market.

💔 Despite its rocky start, Apple released an improved version in 1981, known as the Apple III Plus, which addressed many of the initial issues. The Apple III ultimately did not achieve the commercial success Apple had hoped for, with only about 65,000 units sold. Nevertheless, the Apple III played a crucial role in Apple's development. The lessons learned from its challenges influenced the design and engineering of future Apple products, including the highly successful Apple Macintosh.

💾 The Apple III stands as a fascinating chapter in the history of computing. While it may not have achieved the commercial triumph of its predecessor or successors, its ambition and the innovative spirit behind its design left an indelible mark on Apple’s evolution. Today, the Apple III is remembered as a symbol of both the challenges and the relentless drive for innovation that characterize Apple's journey.

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.

I am going to tag as many fandom tags as I can for the things I generally talk about, to say this.

The People of Palestine need our help.

On my blog, I have consistently reblogged GFM posts from Palestinians who need it, and would love for more people to contribute as well.

Just search "Palestine" tags on my blog or just scroll through and you should find plenty, reblogged as of July 21st.

Please. The people of Gaza need our help. Let us all push for a Free Palestine. I do not care about "oh don't bring fandom into this" because all eyes must be on Palestine during a time like this.

Hot take but if I buy something I think I should own it :/

step 1: build a professional-looking, ad-free site that will perform formatting and validation on a wide variety of file types used for configuration and data transfer (.properties, YAML, .config, JSON, etc), and decrypt file contents if people will just paste in their handy dandy private key/shared secret/etc. Yes, there are already sites for this stuff, but they're fairly scattered and ad-infested.

step 2: perform whatever SEO skullduggery is needed to get your site to the top of the Google search rankings.

step 3: once your site has established itself, pass every single thing that gets pasted into it to a backend service. If you wanna be coy about it, continue doing the validation in Javascript and pretend that the backend calls are metrics. Listen, if you make the URL something like https://admin.yourhosthere.com/datadog-agent then 90% of devs are gonna go 'yeah that seems legit, it's just my good friend Datadog :)' and investigate no further.

step 4: parse every message for strings like 'username' and 'password'.

step 5: now that you have production credentials for about 40% of international corporations and governments, hold the planet hostage.

step 6: rule the world from a flying volcano lair staffed with jumpsuit-wearing henchmen.

(traditionally the henchmen would come before the world conquest, but like most things, supervillainy has gone through massive changes thanks the internet)
