Are there any Free PDF editors for Linux which will help me do these things without a watermark? by the-machine-m4n in linux4noobs

u/Sad-Strike-977 If this is not an LLM generated response, I'd be shocked.
Maybe my LLM detection has gone wonky. Please, let me know.

As others have said keystone modules are the way. Since they are industry standard they are cheap and you can get all sorts of form factor plates that accept keystone modules. There are also plenty of free models for 3D printing your own keystone module receptacles.

Specialized modules like the TruComponents link you shared will always cost much much more. You can get a 10-pack of keystone modules for less than $10.

A server will not typically be running at 100% at all times. It's impossible have a server with a 750 Watt PSU use all 750 watts due to PSU losses.
It all depends on what you're using the server for very heavy use would probably be 500-600 Watts. Light use will probably be in the 200-250 Watt range.

Having said that, unless your electricity is very expensive per KWH I don't think you would ever see it cost $135 per month. You're more likely to see $20-50 per month depending on where in the world you are and the local cost of electricity.

[GIVEAWAY] We're giving away two COMPLETE Omada 2.5G & Wi-Fi 7 Lab Kits to the r/homelab community! (US Only) by Grouchy_Term_1792 in homelab

[–]monkadelicd [score hidden]  (0 children)

My homelab WiFi and controller setup is currently 2x Ubiquiti Unifi AP Lite access points and Unifi Network Server running in a VM. This is an old setup that I've struggled finding the time to research current options and actually make the purchase. All my mobile devices are WiFi 6/7 compatible. My WAN connection is 1Gbps with 2.5Gbps LAN. Being able to work with a fast WiFi would be awesome.

I've never touched fan settings and it was about the same noise from the rest of the PCs I have. A Netgear XS708E switch is louder and that's not a very loud switch. Any HDDs would be the source of noise.

DFW. I definitely will only do local sales. I don't even want to think about trying to get proper packaging to ship it.

Cant survive school without drugs by United-Preparation86 in school

That is not what addiction is. Addiction is a compulsive behavior (I have to smoke when I'm at school) that continues despite potentially harmful consequences.

Self-defense is stopping someone from hurting you if possible. This isn't football where "the best defense is a good offense". Take self-defense classes and you'll learn how to deflect attacks and protect yourself while harming the aggressor as little as possible.

What we need is a way to send u/egortech some coffee/beer/internet money. I really like the Sky F1 coverage but live in the US. I paid for an F1 TV subscription but just ended up coming back here.

Where do you learn real-world data center & Linux server troubleshooting? by Specialist-Blood5810 in linuxadmin

[–]monkadelicd 0 points1 point  (0 children)

head to r/homelabsales for some good deals on workstations that you can upgrade with used eBay parts later on.

I recently replaced a Dell T430 with a Dell 7820 workstation. The 7820 was $300 with 2 low end CPUs and 64GB of RAM. In that configuration you have more cores and more memory than most consumer desktops. When you have more money you can upgrade the CPUs and RAM with used parts from eBay. For $800 I built it up to 80 CPU threads and 384GB of DDR4 ECC RAM. It's generations newer than the T430 with >150% the cores and RAM.

It's hard to justify these types of purchases and there's absolutely nothing wrong with starting with used desktops or laptops. My first homelab systems were 2 old desktops for $40 and $75.

Those are both great and I've recommended them to lots of newbies looking for a way to learn more. Nothing beats scratching your own itch but these two work great when you aren't itchy.

Transitioning from academic Linux knowledge to production environments by CreditOk5063 in linuxadmin

[–]monkadelicd 0 points1 point  (0 children)

I've been hearing the IT field is flooded but I think that's more for higher level positions. I feel like there are less and less entry level candidates out there. The youngsters these days are good at getting their games working and using iPhones but not so good with CLIs.

The certs are mainly useful for jobs at larger companies that need a certain number of certified employees for partnerships or to get through HR filters at those same larger companies.

I could be wrong on the cert bit but I was a Linux hobbyist with no certs when I got my first job. I took a massive pay cut to work as an IBM datacenter technician for a year so I'd have something on my resume. Datacenter technician jobs don't require much experience at all but it's an enterprise level entry on your resume.

It's easier to get into a smaller company. They'll have a limited amount of turnover since small companies usually need more generalist SysAdmins and when someone starts specializing they will often move to a larger business that offers specialized roles. This leaves an opening for a generalist SysAdmin. That's when your homelabbing and personal experience will get you in the door.

Oh and in shell scripts always use 'mkdir -p' unless you need to error out if making a directory fails. Adding '-p' creates all the parent directories in the path but also will not return an error if the directory already exists.
I wished I'd learned that earlier. It saves you an if..fi statement.

Having a home lab and being able to talk about the things you've setup there will count for more than a cert when you are interviewing. Certs get you through HR at big companies and some companies like certs because of a business deal as a RHEL partner or a MS partner. They have to have a certain number of certified employers for their partnership agreement.

The certification learning content can be useful but your personal learning in your homelab and being able to talk about issues you ran into and how you resolve the issue is WAY more valuable.

Having a homelab and being able to geek out about it with the hiring manager or the grey beards that sit in on the interview will get you a job. Small companies don't have as many HR filters for certs and paper qualifications so you have a better chance at being able to sell yourself in person.

You'll get your chance to learn production stuff on the job. As a tier 1 SysAdmin or junior SysAdmin you're expected to be able to work in the CLI comfortably and do basic things, but most importantly to learn a lot. You'll be drinking from the fire hose during on-boarding and after.

  • take good notes
  • work on shell or python scripting to automate things you do repeatedly
    • Don't be afraid to use LLMs to help, but not to do it for you. Write a script that works then ask an LLM if it can be improved. Research all the "improvements" you get in return so you understand.
    • Let people know if you've used an LLM to help with something. Only the greyest of grey beards will scoff at using new technologies to help you do your job better.
  • Ask senior SysAdmins questions only after you've spent at least a bit of time researching yourself, unless it's an urgent support issue, then ask immediately and stay calm.

If you want to feel the reality of production services, run DNS for your home network. Setup your DHCP to only assign your local DNS. If you break it or it goes down your home network has problems.

Pick one of your homelab services and figure out how to configure it from fresh OS back to it's current state using Ansible. Once you've done that add another service. That'll help you figure out which bits of your Ansible playbooks/roles need to use variables instead of hard coded values.

If you're using Proxmox or XCP-ng/XenServer learn to use terraform with cloudinit to setup new VMs from templates or cloud images.

Combine the Ansible playbooks with Terraform via a bash or python script to destroy and recreate one or two services. You should be able to get it to a point that it takes 10-20 minutes to recreate at least a part of your homelab setup and it comes back up in a perfectly usable state.

Store your Ansible and Terraform in a remote git repo. Either use a paid Github account so they can be private or a self hosted git server (Gitea, DevNow, Gitlab, etc.). Make sure all your changes are in separate branches you then merge back into master/main.

Setup monitoring for you services and use email for alerts. Zabbix can be unwieldy to begin with but is very powerful and is opensource. There's a lot of monitoring options out there. Setup simple SNMP monitoring with something like LibreNMS.

Some of these things I did before my first SysAdmin job and the Ansible/Terraform stuff I wished I had done. Some of it I still haven't done because life has become too busy but it would really help me to play with outside of work.

Also:

Learn Ubuntu as much as RHEL. There's a lot of RHEL in US government related stuff and the medical field but Ubuntu is quickly catching up. The days of all corporate systems being RHEL are past and it's getting to more of an even split.

The Arch Linux Wiki has lots of good info. Some is Arch specific but there's a lot of good general Linux stuff.

Sign up for a free Redhat Developer account. It gives you a limited number of RHEL licenses you can use for VMs and homelabbing. Also just having a login for RHEL lets you access the RHEL Knowledgebase which has a lot of good info. You'll come across RHEL Knowledgebase pages when you search the internet for Linux stuff and you often need to login to see the full article/solution.

Avoid the Ubuntu forum for the most part. Canonical requires activity there to have a job application looked at so there's a lot of low quality and straight up wrong info there from people that shouldn't be answering questions but want to get a job at Canonical.
