A comparative deep dive into ext4, NTFS, ZFS, FFS, BFS and APFS — crash consistency, snapshots, CoW and tradeoffs

Your "Conservatively estimated failure rate" section is absolute nonsense. Suggesting that growing an NTFS filesystem has a 2-5% data loss rate is ludicrous. That means that for every 20 partitions you extend, one of them has a catastrophic failure that necessitates recovering from backup. Absolutely absurd. And a 10-15% failure rate for NTFS shrinks? Get out of here. Both are completely supported by Windows and failure rates are essentially 0%.

Everyone’s using AI at work now. No policy. No logs. What could possibly go wrong?

Posted by HalForGood@reddit | sysadmin | View on Reddit | 140 comments

crackerjam@reddit

I feel like a good approach is: 1. Block public tools (e.g. chatgpt.com) 2. Allow approved enterprise tools (e.g. Copilot enterprise, github copilot, etc) 3. Do the same sort of code review you should have been doing this whole time to find quality issues. If you only allow AI on platforms that protect your data, you don't need to worry about audit trails or confidentiality issues. Shadow AI doesn't really matter, because users are still responsible for what they implement. If you have some user that just starts running bad scripts that break things eventually they get fired for constantly breaking things.

I use Gemini (pro) as an advanced form of googling, since it'll do live google searches and summarize the results. Also, coding with Github Copilot in VS Code is a game changer. I spend a lot of time working on Python apps, and a lot of the time I can just write out a docstring and Copilot will fully populate a method. Or, I can start making changes, Copilot will pick up on the pattern of changes I'm making, and start recommending edits. I also use it pretty exclusively to write frontend code for my web tools. It's a massive time saver. Sometimes it make mistakes, sure, but usually I can fix it myself or follow up with "x isn't working right, make it do y instead" and it'll do that just fine.

Self hosting containers - does it require a principal of redundancy for all infrastructure?

Posted by man__i__love__frogs@reddit | linuxadmin | View on Reddit | 15 comments

Containers are just a fancy way to run isolated processes on a server. If you want a reliable postgresql service you need to design it the same way you would if you were just installing it straight into the VM.

What distro is considered the standard for server usage?

Posted by sdns575@reddit | linuxadmin | View on Reddit | 204 comments

crackerjam@reddit

RHEL is very much the "Nobody ever got fired for buying x" choice. Solid, enterprise support, but expensive. Every commercial Linux product is going to support RHEL as well, so you can be confident in that ecosystem. Debian is the answer when you want another rock-solid OS, don't want to pay for it, and don't care about support too much, though it does technically exist. A fine answer when you run a lot of other FOSS stuff and have solid engineers to work on it. Ubuntu tends to be the choice for smaller/newer orgs. Reliable enough, but not as solid as Debian or RHEL, commercial support available, good 3rd party product support, and has some more bleeding edge features. Though, I've never found myself really wanting for those features. Also great for end user Linux if that's your use case. SLES is what you use if your head admin is over 50 and decided 20 years ago that he likes SLES.

Sorry to be brutally honest, but if you're at a junior level you don't have the experience or domain knowledge to implement technology or process changes. Learn the existing environment, present ideas to your seniors if you want, but accept that you don't know everything. Get experience under your belt and then start getting more responsibilities.

Tapes vs "Immutable storage"

Posted by sysacc@reddit | sysadmin | View on Reddit | 166 comments

crackerjam@reddit

Yep! Personally I would still prefer local though, at least for primary backups. An LTO-10 tape holds 30TB raw, and is about $300. The tapes will last a decade of normal use, easy, and at $1 per TB per month of glacier storage, you've broken even on storage after just 10 months. That doesn't include the cost of the actual library and tape drives of course, but when you'd dealing with large scale amounts of data it's only going to add another few months before you break even. Not to mention that you don't have to rely on your internet speeds to send or receive backups.

Posted by sysacc@reddit | sysadmin | View on Reddit | 166 comments

crackerjam@reddit

Everybody complaining about how slow tapes are has never experienced a modern tape library. You can have an automated library with multiple tape drives each writing or reading at 400 MiB/s with modern LTO-10 tapes. No human interaction needed, you just have a big box with 30 TiB of uncompressed capacity per tape, and hundreds if not *thousands* of tapes. You're not going to get that kind of capacity and performance with any cloud solutions, and any hard drive solution that can match it is going to be substantially more expensive.

Integrate into the team more, master your area, and then use your position to influence change. If you just start telling people what to do they'll hate you forever and you will be miserable.

In that case you have a test environment, and no prod environment. Run `apt-get upgrade -y` and yolo, that's the best you can do. All Ubuntu package are tested by Canonical and the community before they're released, so in theory everything should work fine, but if it doesn't in your environment the only way to know is to test.

Posted by Homesick97@reddit | sysadmin | View on Reddit | 822 comments

IT is an enormous field. There are roles where all of your time is spend dealing with absolutely braindead users that need their hands held for everything, and other roles where you're in a code editor all day with minimal human interaction outside of Jira tickets. Likewise there are companies that will middle manage you into jumping off a bridge, and others that won't bother you as long as your tickets are being done. The key to success in this field is finding the right role and the right employer for your own success.

Red team hacker on how she 'breaks into buildings and pretends to be the bad guy'

Posted by throwaway16830261@reddit | linuxadmin | View on Reddit | 10 comments

crackerjam@reddit

Banks absolutely hire red teamers for physical pen testing. As a pen tester you need a C-level signature on your contract from the company you're actually penetrating, otherwise you're open to a shit load of liability. > In that case the sec guy would be in a building with permission from the building, with a contract, and he have little ways to know the building owner does not own the conference rooms. He would have to get out of the way to investigate if the signer of the contract owns every asset specified on the contract, and I doubt red teamers would do that. He would walk through a door labeled "Bob's Online Mattress Sales" and immediately be on the hook as he's entering property that is clearly can't be authorized by ACME as another company's name is on it.

> In this case, the command-and-control server happened to be controlled by a security firm's red team that had been hired by the multi-tenant building owner who was worried about the inhabitants being "a little too relaxed" about office security — so this stolen data wasn't being sent to a criminal's C2. I believe this sort of thing happens, but this line makes me call bullshit on this particular story. In no universe can a building owner hire someone to hack a tenant's systems, and no security professional would ever take a job like this. It's 100% illegal and they and they would be in prison as soon as the target business found out.

NIST proposes barring some of the most nonsensical password rules

Posted by Big_Blue_Smurf@reddit | sysadmin | View on Reddit | 357 comments

crackerjam@reddit

Is it just me or do those password requirements seem a little too lax now? > Verifiers and CSPs SHALL require passwords to be a **minimum of eight characters** in length and SHOULD require passwords to be a minimum of 15 characters in length. > Verifiers and CSPs SHOULD **accept all printing ASCII** [RFC20] characters and the space character in passwords. > Verifiers and CSPs **SHALL NOT impose other composition rules** (e.g., requiring mixtures of different character types) for passwords. So like, "12345678" is fine? Not requiring regular password changes is good, but there should really be a 20 character minimum or something more substantial.

I'm pretty passionate about tech, it's why I got into the career in the first place so that spills into my home life too. I've got a few gaming PCs around the house for the family, some ethernet through the walls, enterprise networking and wifi, 3d printer, a bunch of consoles, rokus all over, media room with a projector.... And, there's a big server in the basement with a bunch of VM to run stuff. All of my VMs are built through Terraform and Ansible with all of the source hosted on a gitlab instance. It's definitely a lot, but I've enjoyed setting things up. Oh, I have a tape library attached to the server too.

CEO wants everyone to use an AI. I have zero idea on what I can use it for.

Posted by CMageti@reddit | sysadmin | View on Reddit | 724 comments

crackerjam@reddit

I use github copilot with VS Code for Ansible playbooks, python, powershell, and bash scripts. It's basically just really smart code completion. Like, in many cases you can create the bones of a function with a docstring and just ask the AI to fill in the rest, and it will do so properly. It doesn't do everything, and sometimes it gets things wrong, but it's extremely useful for this and cuts down dev time dramatically. 2x is not an exaggeration IMO.
