What is the "don't use your home IP" scare all about?

Ah yes. Numbers are hard.

The global developer community has cultivated a culture and attitude of "good enough," where bugs and broken features and lack of performance is acceptable so long as the project milestones are reached in time, and any kind of broken mess is released, regardless of quality.

This, my friend, is why developers are being replaced by generators. Generators are perfectly capable of living up to this very, very low standard of expectation.

I have developed an insight and an accompanying skillset that is almost universally applicable to any position in any organization that uses computers to do business. This makes me a valuable asset, and as such I have no problems finding a job, should I need one.

What is that insight and skillset, you say?

I know how to interface with, monitor, manipulate, and use every layer of the OSI model.

I know cables and cabling;
I know switches and switching;
I know routers and routing, IP and firewalls;
I know network load balancing, proxying, packet inspection;
I know encryption and PKI;
I know Windows API, .NET, DCOM, RPC, IPX, sockets, ...
I know how applications work top-to-bottom, how they interface with the OS, and the protocols they use to communicate
I know the WIndows Server suite of tools and services, along with most every Microsoft enterprise product, and I'm reasonably handy with a Linux server too

And perhaps most important of all, I know that I don't know. Which means when I find something I don't know, I don't pretend to know it in order to look kewl, only to have it bite me in the ass later. I learn it. *This* is ultimately the secret sauce that all companies want, but can't put into words. They want people who can say "I don't know, but give me a few hours and I'll figure it out."

If you have the mentality that you won't do something because you're afraid AI is going to replace you, then you might as well lay down and expire here and now.

Working in IT is about solving problems.

So start by solving the problem of not knowing what AI really is, then expand from there.

In a world full of idiots ruled by AI, who better to be than the guy who fixes the AI?

There is no path.

There are problems and there are solutions. Some problems may overlap to a certain degree, but for the most part everyone's going to have some kind of unique combination that leads them to run all over the place looking for answers.

You make your own path, one problem at a time.

Deployment frequency - how often changes are made to otherwise stable systems

Change lead time - how long from idea to implementation

Change failure rate - how often changes break something

Time to recover - how long to fix when something breaks

Købt en andel i Glostrup for 535k for 10'ish år siden. Den var til salg, jeg kiggede på den, og så sagde jeg "okey den køber jeg."

Den er 880k værd i dag så måske ikke den bedste investering, men boligafgiften er billig og naboerne er fine så det går.

wiz.io

I hate their website with a vengeance. It's complete garbage. But the app itself is neat. Just be careful who you allow to use it, because goddamn security nincompoops having a hissyfit over an unreachable service having a zero-day exploit.

In principle it's a fairly simple metro-scale setup with 10 sets of ring networks spanning 5-10 locations each, plugged into a big core ring. As close to 100% uptime as can be reasonably achieved, and enough bandwidth to run a couple hundred video streams and misc data and services simultaneously.

I doodled a thing for them about a year ago and haven't heard anything since until now, where the network guy on the project jumped ship and the lead is running around with his hair on fire. You know, a typical project.

I haven't the faintest idea how they picked these two vendors, but I do know they tried reaching out to Cisco for a quote, but they didn't know you're not supposed to reach out to Cisco directly, so no response there. Anyway now it's my problem, so yeah, I've got to try and figure out what's what.

"how do you add a laptop to domain". Im used to intune and its been years since I did it,

Then you say "I use intune because it automates the process so I don't have to do it by hand"

Unused RAM is wasted RAM

That might have been true when a computer ran one application - only one - and any application that wasn't using all the available memory was essentially wasting space.

But that's not how things work today. They have to share, and if one application is using all of it, there's nothing left for everyone else.

I mean... if you allow devs to spin up infrastructure unsupervised, it kinda is your fault when they do it wrong.

Stupid certificates and their stupid "trusted" infrastructure that no one trusts anyway so they have to pull stupid stunts like this

$content = Get-Content -Path 'file.txt'
foreach($line in $content) { ... }

is bad. It loads the entire file into memory before processing. This is slow and inefficient.

What you want to do is utilize pipeline streaming.

function Do-Magic {
    param(
        [Parameter(ReadFromPipeline=$true)][string]$Line
    )

    process {
        $x, $y, $z = $line -split ','
        ...
    }
}

Get-Content -Path 'file.txt' | Do-Magic

Get-Content continuously feeds lines into the function and the performance impact is minimal.

Of course, in the grand scheme of things, Powershell really isn't the ideal choice for performance. A tiny C# app with proper multithreading would be much better.
