Reinstalled my dedicated server yesterday.

Then you suddenly get errors saying that KVM isn't found.

Searching my ass off for hours because I damn well enabled Intel virtualization in the bios!

Double checked after a few hours.

THE FUCKER TURNED ITSELF OFF OR SOMETHING FOR THE SECOND TIME?! WELL, THERE GOES A FEW FUCKING HOURS 😡

Best thing about devRant is that if I rant here, I don't need to look like a jaded sociopath on Facebook any more. 😉

Saw somebody post an XP install DVD, remembered I had this kicking around...

So 10 months ago i moved from Cambridge (UK) to Guildford (UK), due to moving this distance i started working from home and going into the office once a week.

Now after 10 months i have finally got my home office how i first imagined it. Everything runs from my laptop which is located on the shelving unit away from my desk. Everything plugs into it via 1 USB lead.

Setup:
27" 2560 x 1440 monitor flanked by two 1280 x 1024 monitors.
Asus Laptop (i5-6300HQ, 12GB ram, 512GB SSD + 1TB HDD)
Home PC (i5-7600, 8GB ram, GTX 770)

Accessories:
StarTech USB hub - This allows me to plug my three monitors, keyboards, mouse and everything else into my laptop.
KVM switch - Allows me to swap between my Work PC and Home PC with a click of a button

Fuck Apple even more than before. Keep all your proprietary garbage, I don't need any of it.

On reccomendation of @chabad360 I made this its own rant.

I switched from marketing to CS (complete with a three year degree, no Bootcamp). I still went to interviews as you'd expect a marketing man to go; in a suit. Commence the weirdest interview.

$I: interviewer
$M: Me

I: "You're not the typical engineer. Can you talk to real engineers?"

M: "could you elaborate"

I:"you're dressed in a suit. That leads me to think you're a MS user. Do you think you could talk to real, ie. Linux using engineers?"

M: " well, I haven't used windows in about a year soo..

I: "Mac isn't Linux."

M: "I'm aware. I've switched to Ubuntu so I could use KVM-QEMU android emulator with GPU pass through to train Deep Convolution Networks on mobile devices. Also had to compile Google's internal build tool because it had bugs I had to fix so I could compile the APK."

I: "ah, Ubuntu eh? **Insert Smirk** How about a follow-up?"

M: "no, I'm switching to Gentoo this week and would like to talk to real engineers about that."

I thanked him for the coffee and left.

Tests!

Before you write a piece of code, write tests which will check that the code does what you expect. This helps you in two ways:

1. It forces you to think about and understand the purpose and aim of the code you're about to write before you start hacking away at it.

2. You know when you're finished, because the tests will pass.

What I like to do when I'm bored...

Finally dumped windows from my tower/gaming rig!!!

I'm now running Ubuntu Budgie and Windows 10 inside a qemu/kvm VM with gpu passthrough. That way I have almost-native performance and no additional setup effort for installing games.

Got a second 1080p monitor for Xmas ans it gave me an excuse to clean my desk off ;)

I included the obligatory 'screenfetch' window as well, haha.

Now to see if I can hack together something resembling a KVM switch from parts I have, to use the Mac mini on one of them (when it's needed on rare occasion, lol).

P.s. I'm sure many of you have more bad ass setups, I even used to have quads myself... But I'm not posting this to start some pissing contest! It's just mine and I'm proud of it :P

Happy new year everyone!!!!

About slightly more than a year ago I started volunteering at the local general students committee. They desperately searched for someone playing the role of both political head of division as well as the system administrator, for around half a year before I took the job.

When I started the data center was mostly abandoned with most of the computational power and resources just laying around unused. They already ran some kvm-hosts with around 6 virtual machines, including a cloud service, internally used shared storage, a user directory and also 10 workstations and a WiFi-Network. Everything except one virtual machine ran on GNU/Linux-systems and was built on open source technology. The administration was done through shared passwords, bash-scripts and instructions in an extensive MediaWiki instance.

My introduction into this whole eco-system was basically this:
"Ever did something with linux before? Here you have the logins - have fun. Oh, and please don't break stuff. Thank you!"

Since I had only managed a small personal server before and learned stuff about networking, it-sec and administration only from courses in university I quickly shaped a small team eager to build great things which would bring in the knowledge necessary to create something awesome. We had a lot of fun diving into modern technologies, discussing the future of this infrastructure and simply try out and fail hard while implementing those ideas.

Today, a year and a half later, we look at around 40 virtual machines spiced with a lot of magic. We host several internal and external services like cloud, chat, ticket-system, websites, blog, notepad, DNS, DHCP, VPN, firewall, confluence, freifunk (free network mesh), ubuntu mirror etc. Everything is managed through a central puppet-configuration infrastructure. Changes in configuration are deployed in minutes across all servers. We utilize docker for application deployment and gitlab for code management. We provide incremental, distributed backups, a central database and a distributed network across the campus. We created a desktop workstation environment based on Ubuntu Server for deployment on bare-metal machines through the foreman project. Almost everything free and open source.

The whole system now is easily configurable, allows updating, maintenance and deployment of old and new services. We reached our main goal for this year which was the creation of a documented environment which is maintainable by one administrator.

Although we did this in our free-time without any payment it was a great year with a lot of experience which pays off now.

So I started using this KVM over IP software called Synergy. I'm really digging dragging my cursor (and clipboard contents), from a Windows machine, to OSX, to Linux Mint.

Tonight I rest well...

Recruiters or their bosses with sick ambitions and zero feedback.

Do I need to say more?

Spent few days to make my site looking good on desktop/mobile with few screenshots and even video to show my working projects in production. Even more few days to make really detailed 2 A4 CV with my previous job and what I was doing there. All generated from markdown.

I even saved money around half a year to go and live month in other country (Ireland, Dublin) and then on site send about 150 applications on various sites, emails, linkedout and local IT meetings.

Null, nada, nil, NaN accepted applications.

Is it some kind of joke? All companies almost cries for new workers and they don't even answer someone which founded and have no problem with growing own IT company for almost 5 years with self learnt, practically applied in production linux, HTML, CSS, JS, PHP, Go, bash, KVM and Openvz virtualization knowledge?

What they really want?
Astronaut with Brainfuck and Cobol with fluent backwards speaking Esperanto riding on monocycle with 3 hands and no need for sleep for -1 whoopercoin?

How have I not used KVM before 5 minutes ago? Am I mentally challenged?? This makes my work load wayy easier

Debugging gone wrong.

I've been developping some software so an entire debian OS gets bootstrapped and installed with all the desired software with the help of puppetlabs software...i need to prepare a server that can handle virtualization and be fast at it. So all the goodies a decent server needs, the apt, caching, networking, firewall, everything checks out... I want to test kvm virtualization... Doesn't work. Wtf? Spend a decent amount of time figuring out what the hell is wrong... I finally dzcide to think 'what if my buddy accidentally gave me a bad mobo'...

$ grep -e (vmx|ssm) /proc/cpuinfo

Nothing...

I feel so stupid to not check the mobo virtualization capabilities.

I use qemu/KVM on Linux. I love being able to do basically all VM operations with commands. So when I need to use my Windows VM(ie: connect to a WebEx), I pop it on with an integration I wrote for my keyboard launcher(mutate), or just execute an alias over SSH, and connect via VNC. When I'm done, I just shit it down. At this point, Windows has been reduced to just a windowed program that I run.

Always comment your code.

Write comments that explain the reason for this piece of code existing, and why it's written the way it is.

Don't write comments that explain what your code does (unless it's a comment which is going to be parsed as documentation for an API). If your code needs comments to explain what it's doing, you need to write clearer code.

Feature suggestion: detect links to other rants and open them in app?

Like a lot of school kids in the UK, I learned BASIC on a BBC Model B and later BASIC/COMAL on my Archimedes A3000.

It taught almost nothing relevant to real programming. A terrible and inefficient way to learn! But there were no better resources then. No Internet access.

Has anyone figured out how to use a magic mouse with a kvm? I have a kvm which I am thinking about putting a Bluetooth dongle into and pairing with magic mouse. Does anyone know if this would work?

Whoo, I think I halved the cable mess on my desk since I *finally* removed my old 4-way KVM-switch! (I haven't used PS/2 keyboards/mice for a long time anymore..)

How do I get my hands on devRant stickers?
My laptop requires them.

I successfully PCI passed through my nvidia 970m to Bluescreen-OS on a nvidia optimus laptop.
Totally useless, if your GPU does not have any video output ٩๏̯͡๏۶

What's the point about having an HDMI output, if it neither works with the intel 530, nor with the 970m? Is it even connected? I mean, srsly, why would you do that? Best Linux support ever!!!1!!!
