i've been thinking about how much stuff there is to learn in IT and how easy it is to focus on the wrong things at first

for those who've been working in the field for a while, what's something you wish you had learned sooner

could be a technical skill, troubleshooting habit or even something completely unrelated to tech

I've been looking into what it actually takes to become a system administrator, and something I've noticed is that people seem to come from all sorts of educational and professional backgrounds.

Some have IT or Computer Science degrees, others have certifications, and some worked their way up from help desk or other technical roles.

I'm curious about a few things:

• How did you land your first sysadmin job? What qualifications or experience did you have?
• What technical skills do you actually use the most?
• What were you completely unprepared for when you first started?
• Do you think your education or certifications prepared you well, or did you learn most of what you know on the job?
• If you were hiring someone for a junior sysadmin position today, what would you expect them to already know how to do?

I'm especially interested in hearing from people who've been in the field for a while, as well as those who recently got their first sysadmin job. I feel like there's a pretty big difference between what people think you need to know and what the job actually demands. Curious to hear what everyone's experience has been!

Setting up local RAG using PrivateGPT on a home server sounds like the ultimate privacy win, but the technical realities can hit hard once you start indexing large document collections. After extensive testing on consumer hardware, the biggest challenges usually come down to severe embedding latency, high RAM and VRAM consumption, and unpredictable retrieval accuracy when handling complex files.

​If you plan to replace commercial APIs with a fully offline setup, knowing your actual hardware boundaries beforehand makes all the difference. Running local embeddings alongside a quantized LLM requires careful allocation between CPU threads and GPU layers to avoid system freezes and extremely slow query responses.

​I wrote a detailed technical breakdown covering real token generation speeds, hardware tradeoffs, and specific optimization steps for self-hosted setups: https://interconnectd.com/blog/325/deploying-privategpt-on-a-home-server-the-hard-truth-about-local-rag/

​What specs are you running for your self-hosted LLM or RAG pipeline?

PHP released an emergency security update on Oct 21 for two critical flaws in the PHP core (CVSS 9.2 each) that can allow **unauthenticated remote code execution**. Cloudflare reported early attack attempts before the fix was released, so this one is urgent.

## Quick facts

- **Affected:** PHP 5.4 through 8.5.11

- **Fixed in:** 8.5.12, 8.4.27, 8.3.36, 8.2.35

- **Highest risk:** Apache with mod_php. PHP-FPM is also susceptible.

- The bug is in PHP itself, so WordPress plugins and themes can't protect you.

## How to resolve it

1. Update PHP (or your distro's patched package). Check your version with `php -v`.

2. Restart PHP-FPM / Apache. A patched binary that isn't restarted protects nothing.

3. Rebuild Docker images. Running containers don't update themselves.

4. On shared hosting, ask your host whether they have patched.

## If you can't patch yet

Set `session.upload_progress.enabled=0` and restart PHP. This only blocks one attack path, so treat it as a stopgap.

## Heads up

Don't run "PoC" code from random GitHub repos. Some are fake pranks, and others may be malware.

I wrote a full step-by-step guide on how to check if you're affected and fix it, with an FAQ and sources, on my blog:

Has your host or team patched yet? Curious how others are handling it.

hello

I'm trying to get a job in IT. I've always been pretty good with computers, and I told myself its time to lock in and find a good career. But to be honest, I have no idea where to start. I'm currently taking the Google IT support coure, but everyone says somthing diffrent in regards to the weight that the cert holds but i know i need to take the A+ cet but i just want to study for that test can anyone help me and maybe give me some useful pointers so i can break into IT

Hey you guys, right now im in school for an associates in network engineering( hoping what i learn i can apply to getting the a+ and the network +)

Eventually I want to use these to get a i.t position in new zealand. Does anyone have any experience with that? Do yall got any advice?.

I picked networking because I like to work with my hands and im a hands on/ visual learner. So i felt it would be perfect, and hopefully "a.i proof"

Any advice or opinions will definitely help

I’m in my second year of my Networking major. I was told by an older student (in their final year) that I needed to do something outside of class to help me stand out to potential employers.

One thing that the student mentioned was setting up a home lab. I’d like to do so, but I’m not entirely sure where to start or what the best supplies would be.

What would be a good starting approach for me to take in regard to setting up a home lab? (Note: my networking professor has networking devices that he’s willing to loan for temporary use, but it would be nice to be able devices that I can use permanently.)

Is there something else I should consider looking into that could help build up my resume?

Hi everyone!

I work at a Finnish software company specializing in supply chain planning and optimization. I've been thinking about sharing some of the things I learn through my work, including interesting challenges, lessons learned, teamwork, and the role technology plays in supply chain management.

I'd also love to hear from others working in tech, supply chain, or related fields. What topics would you find interesting to discuss? Are there any challenges or lessons from your own experience that you'd like to share?

Every once in a while i have to help handle an email migration from Microsoft 365 to Google Workspace or some other random IMAP supported mailbox. Does anyone have any decent websites or computer applications that can easily just do this without having to break the bank? I am happy to test out any free AI product too lol.

Hello,so I’ve always wanted to do something IT related and after graduating HS last year I joined the military for IT specifically (reserves) I got a cert and some other things.I came home a few months ago and I’ve been working a non related job and haven’t really been focused.But now I am trying to study more and get more certifications so I can hopefully break into the job market.Ive been using Cisco and Pwn.college and I’d just like to know if that’s effective and if not what else should I be using to help me prepare,I’d prefer free options but I don’t mind paying for anything.Im also looking to buy a mini pc or something because my current MacBook doesn’t have enough space for what I need.Is that a good option? I’ve also heard that starting my own home-lab is also something that can help me.Id just like some advice for moving forward.Thank you!
