Canadian MP demoted for supporting restrictions on arms exports to Israel

Note: These are my learning notes from my current phase. I am keeping them as I wrote them so I can look back and see my progress.


watched a 1 hour history of linux, basically where it cme from, how it came by and the early struggles(on 1.5x).

Next: bash scripting and command lines for beginners.


A bash script is a file containing sequence of command executed but bash program line by line. like a file where the command lines are saved so you dont need to retype them everytime.

downloaded and install linux, and ubuntu and did the installation. used sudo hostnamectl set hostname devbox and then used sudo nano /etc/hosts to edit my terminal name.

the superuser shell uses # as it anchor while normal user uses $ sign.

i wrote my first script. to write your script you need the she bang which tell the terminal how to run the script. #!/bin/bash and you follow it with your script.
echo command litrary echos whatever you write back to you. read pauses the script so you can input and $ holds the value of your variable. to write a date now here is how to write.

#!/bin/bash
echo “Today is `date` or $(date)”

echo “where do you want the response to be”

read “path”

echo “This is all the responses in this path”

ls “$path”

Note: $(…..) means run the command inside the bracket.

“$name means the name is holding a value.

chmod u+x filename makes the file executable, before that, the file is just text.

\n is new line

-e make it easy to interpret the \n. without the -e, it will not render in a new line. it will render literary.

done < .txt. this take input from the text file. Let say the text file name is name.txt. to take input from it, i will use <name.txt.

$1 this mean you input data at the execution point. e.g ./name Wale. output would be “My name is wale”

COMMANDWHAT IT DOES
ls→ list directory
ls > output.txt→ list directory → save output to file
cat output.txt→ display contents of file
ls output.txt→ list the file itself
echo macho→ produce "macho"
echo macho > file→ produce "macho" → Overite the existiing file
done < output.txt→ takes input from the text file

while loop. sample


i=1

while [[ $i -le 5 ]](logic, if i is less or equal to 1)

do(action)

echo “$i” (write i)

(( $i += 1) (add 1 everytime till it equals to 5)

done (done)

for loop. sample


i=1 (var name)

for i in {1…5} (logic)

do (action.. )

echo “$i”(write)

done(done)

Case Settlements: means bash goes through muultiple case’s you’ve built and return with the most correct and if it cant find the correct, it return with the preset alternative.


eg.

fruit=”apple”

case fruit $fruit in

“apple”)

echo “This is a red fruit.”

;;

“orange”)

echo “This is an Orange fruit”

;;

*)

echo “This is not a fruit.”

;;

esac

bash will check if there is apple in the script and return what echos the text for apple and if it couldn’t find it. it returns what was set to *).

Degugging.


To debut a script that isnt working, you use set -x at the section where you think the error is or you could just put it after the shebang and it will run through the script and give you the feedback.

. What cron does


Cron automatically runs commands/scripts at scheduled times.

Think:

"Run this script for me every day at 2 AM."


2. Know the five fields


* * * * *
│ │ │ │ │
│ │ │ │ └── weekday
│ │ │ └──── month
│ │ └────── day of month
│ └──────── hour
└────────── minute

You don't need to memorize every possible combination yet.

3. Know these two commands


crontab -l

→ See your scheduled cron jobs.

crontab -e

→ Edit/add your cron jobs.

4. Understand one simple example


0 0 * * * /path/to/script.sh

Means:

Run script.sh at 00:00 (midnight), every day.


And:

*/5 * * * * /path/to/script.sh

means:

Run it every 5 minutes.


What I'd skip for now


Don't spend time memorizing things like:

0 0 1-7 * *
0 6 * * 1-5
*/17 2-4 3-8 ...

Computer Networking


LAN → ETHERNET

MAC(media access control) address is an identifier for each system.

CSMA(carrier sense multiple access) → any share transmition that carries date eg cable network or wifi.

bandwidth is the rate at which a transmiter carries data.

Exponential Backoff: to fix the network traffic by making one computer wait in a random time (e.g 1.3secs) to transmit data to reduce collusion.

Collusion domain: this is using a netwrok switch which sit betwen small network ( Read more on this)

Routine: Allocating a communition line for their exclusive use

Circuit switch: **

message switching: **

Hop count: The number of hops a message tales along a route is called the hop count

Packet: A small pieces of message that contains the destination address on the network so router know where to forward them.

IP: this is internet protocol. an identifier.

Congestion control: Load balance

TCP IP:
internet control message protocol(ICMP)

Border gateway protocol(BGP)

IoT

ipv4: is a 32bit data that allows for 232 ip addresses or about 4.3billion unique ips(4 digits)

ipv6: a 128bit data that allows for 2128 unique ips. (38 digits)

IP types - Static and dynamic IP
Static: is a permanent IP address whike dynamic is a temporary Ip address

DNS(Domain name system): This is internet phonebook where all internet website is saved. it works by translating the website into the Ip address so user can access the website.


Types:

  • Recursor → actively goes looking for the answer.
  • Root → points it toward the correct TLD.
  • TLD → points it toward the authoritative server for that domain.


- Authoritative → has the actual DNS record/answer.


!image.png

DNS caching: This temporary stores the inital data results which results to faster response to queries.

What is time-to-live (TTL) in networking?


Time to live (TTL) refers to the amount of time or “hops” that a packet is set to exist inside a network before being discarded by a router. TTL is also used in other contexts including CDN caching and DNS caching.#learning #bash #linux #newbie #software #coding #development #engineering #inclusive #community

How to keep enjoying programming in a world of LLMs

Link: discourse.haskell.org/t/how-to…
Discussion: news.ycombinator.com/item?id=4…

This is not a competition between them; it is just a comparison of the pros and cons of using each.

For me, I have about 6 months of experience with Arch Linux—specifically focused on running local large language models (LLMs). I want to cover how easy each is to use, which one is good for techies, and whether people who are both gamers and techies like me should use Linux or not. Another trending topic I want to address is how much Linux helps when running local models, specifically LLMs.

Using Arch Linux has been a fun experience for me. You get the pseudo-feeling of using a computer for the very first time, and it was a great experience overall. I even dual-booted it without using any USB drive. Yes, Arch Linux was my very first experience with a Linux distribution. Currently, I am using Hyprland on Arch Linux, and more specifically, I am using Celestia Shell, which has been an amazing setup.

Before going deeper, I want to clarify my laptop specs:

CPU: Intel Core i5-11400H

GPU: NVIDIA RTX 2050 (4 GB VRAM, 95W TGP)

RAM: 16 GB DDR4

Storage: 1 TB SSD

1. Beginner Friendliness: How Hard Is Arch Linux Really?
We all know which OS wins the beginner category: Windows. It is designed so seamlessly that even a child can use it. If you are brand new to computers, Windows is naturally where you start.

However, we are talking about developers and tech enthusiasts here. Is Arch Linux really as hard as people claim?

To be honest, it isn't. It is definitely a lengthy setup process, and a wrong move during installation can corrupt your data, but if you enjoy tech, it is actually a lot of fun. Take my experience: I set up Arch Linux without a USB drive. I created a virtual installer using disk partitioning, booted into that partition, and boom—Arch was ready to install.

From there, it was just setting up system configurations using terminal commands. It didn't feel overly difficult for me because I was already familiar with Git Bash, which uses a Linux-based terminal.

If you are a developer, you won't find setting up Linux impossible. In fact, every developer should try it at least once. No matter what field of software development you go into, you will eventually interact with terminals—especially Linux-based ones.

2. Everyday Convenience: Apps & Gaming

Almost every tool used for coding is available natively on Linux, along with a few developer tools that are exclusive to it. Installing packages is straightforward, and the Arch Linux community (and the AUR) is extremely active, so finding the software you need for your workspace is rarely an issue.

For gamers, Linux can present a few hurdles—you cannot easily install pirated or third-party game repacks made strictly for Windows. However, playing games through Steam (via Proton) works amazingly well.

Because Linux uses significantly fewer background resources than Windows, gaming performance can improve drastically. On my machine, games like Red Dead Redemption 2, Ghost of Tsushima, and Minecraft run drastically smoother on Linux. In fact, I consistently get around 15 to 20 FPS more compared to Windows. In Red Dead Redemption 2, with high-to-ultra settings configured, it yields up to 25 FPS more and runs like an absolute charm.

While there are pros and cons depending on whether a game relies on intrusive kernel anti-cheat, Linux handles single-player titles and AAA games surprisingly well if you want smooth performance with optimized settings.

3. Customization & Control
Linux takes a massive lead when it comes to customization. You can build and configure literally every part of your desktop environment to your exact liking.

Windows, on the other hand, is restrictive. It limits how much you can modify, telemetry can feel intrusive, and you don't have full control over background tasks. With Linux, you truly own your system. Freedom and total control are easily the biggest reasons people make the switch.

4. Workspace & Daily Productivity
If your daily workflow heavily relies on native Microsoft Office apps, Linux might require some adjustment. While alternatives like LibreOffice exist, die-hard users of MS Office will need to rely on web versions inside a browser.

Setting up a general shared office workstation is often simpler on Windows. Linux environments (especially custom setups like tiling window managers) are tailored heavily around your personal preferences. If someone else sits down at your customized Linux setup, they might struggle to navigate it.

5. Why Linux Is Superior for Running Local LLMs
Large Language Models require a massive amount of system resources. In my case, I run 4B to 7B parameter models on my GPU.

I get noticeably better performance on Linux compared to Windows. Windows consumes a large portion of your system RAM and VRAM just idling after boot. In contrast, a minimal Linux setup takes up a fraction of system memory, leaving almost all your RAM and processing power dedicated entirely to your actual tasks.

If you regularly run local LLMs or work on machine learning projects, Linux is an absolute game-changer.#ai #linux #llm #programming #software #coding #development #engineering #inclusive #community
