Good Morning!, its time for practiseSafeHex's most incompetent co-worker!

Todays contestant is a very special one.

*sitcom audience: WHY?*

Glad you asked, you see if you were to look at his linkedin profile, you would see a job title unlike any you've seen before.

*sitcom audience oooooooohhhhhh*

were not talking software developer, engineer, tech lead, designer, CTO, CEO or anything like that, No No our new entrant "G" surpasses all of those with the title ..... "Software extraordinaire".

*sitcom audience laughs hysterically*

I KNOW!, wtf does that even mean! as a previous dev-ranter pointed out does this mean he IS quality code? I'd say he's more like a trash can ... where his code belongs

*ba dum tsssss*

Ok ok, lets get on with the show, heres some reasons why "G" is on the show:

One of G's tasks was to build an analytics gathering library for iOS, similar to google analytics where you track pages and events (we couldn't use google's). G was SO good at this job he implemented 2 features we didn't even ask for:

- If the library was unable to load its config file (for any reason) it would throw an uncatchable system integrity error, crashing the app.
- If anything was passed into any of the functions that wasn't expected (null, empty array etc.) it would crash the app as it was "more efficient" to not do any sanity checks inside the library.

This caused a lot of issues as some of the data needed to come from the clients server. The day we launched the app, within the first 3 hours we had over 40k crash logs and a VERY angry client.

Now, what makes this story important is not the bugs themselves, come on how many times have we all done something stupid? No the issue here was G defended all of this as the right thing to do!

.. and no he wasn't stoned or drunk!

G claimed if he couldn't get the right settings / params he wouldn't be able to track the event and then our CEO wouldn't have our usage data. To which I replied:

"So your solution was to not give the client an app instead? ... which also doesn't give the CEO his data".

He got very angry and asked me "what would you do then?". I offered a solution something like why not have a default tag for "error" or "unknown" where if theres an issue, we send up whatever we have, plus the file name and store it somewhere else. I was told I was being ridiculous as it wasn't built to track anything like that and that would never work ... his solution? ... pull the library out of the app and forget it.

... once again giving everyone no data.

G later moved onto another cross-platform style project. Backend team were particularly unhappy as they got no spec of what needed to be done. All they knew was it was a single endpoint dealing with very complex model. There was no Java classes, super classes, abstract classes or even interfaces, just this huge chunk of mocked data. So myself and the lead sat down with him, and asked where the interfaces for the backend where, or designs / architecture for them etc.

His response, to this day frightens me ... not makes me angry, not bewilders me ... scares the living shit out of me that people like this exist in the world and have successful careers.

G: "hhhmmm, I know how to build an interface, but i've never understood them ... Like lets say I have an interface, what now? how does that help me in any way? I can't physically use it, does it not just use up time building it for no reason?"

us: "... ... how are the backend team suppose to understand the model, its types, integrate it into the other systems?"

G: "Can I not just tell them and they can write it down?"

**
I'll just pause here for a moment, as you'll likely need to read that again out of sheer disbelief
**

I've never seen someone die inside the way the lead did. He started a syllable and his face just dropped, eyes glazed over and he instantly lost all the will to live. He replied:

" wel ............... it doesn't matter ... its not important ... I have to go, good luck with the project"

*killed the screen share and left the room*

now I know you are all dying in suspense to know what happened to that project, I can drop the shocking bombshell that it was in fact cancelled. Thankfully only ~350 man hours were spent on it

... yep, not a typo.

G's crowning achievement however will go down in history. VERY long story short, backend got deployed to the server and EVERYTHING broke. Lead investigated, found mistakes and config issues on every second line, load balancer wasn't even starting up. When asked had this been tested before it was deployed:

G: "Yeah I tested it on my machine, it worked fine"

lead: "... and on the server?"

G: "no, my machine will do the same thing"

lead: "do you have a load balancer and multiple VM's?"

G: "no, but Java is Java"

... and with that its time to end todays episode. Will G be our most incompetent? ... maybe.

Tune in later for more practiceSafeHex's most incompetent co-worker!!!

One year ago, I quit my job in order to "make life easier". And by that I mean work+home in the same city. I went from 40 minutes commute - to 3 minutes. I had a blast the first week.

Then I realized that it was actually a mistake. I did not like working with "that kind of systems" and "that kind of tasks". It was tedious, stupid, and I was angry every, single day because the previous ones had built a system on 10-15 year old hardware because "it is cheaper".

That continued for a year. I discovered new stupid "solutions" every week that was potentially dangerous for the company. It built up a huge pile of shit and I started to feel that my mental health was disappearing, fast.

And equipment such as servers, switches, routers, storage started to fail because of age. Despite my warnings from day 0 to the CEO who only kinda laughed it off and said "you can to solve that", but I never got the approval to actually buy the equipment that was needed. Because "the company did'nt have the money for it". Somehow, the company had the money to buy expensive cars for the CEO - I can't really figure out that equation.

So today, one VERY old UPS died at our office. It caused some powerspike that killed off some switches and a NAS.
"Whatever" I thought, I just have to find the backup of the files and get a new one.

Then I discovered, that the NAS that acted as a iSCSI target for VM's and document storage was backed up using VEEAM on another server - that was configured to backup everything to the same NAS. I just wanted to cry, because I could not take anymore shit.

So I picked up my phone, called my old employer and asked if I could start working for them again. My old boss got insanely happy and gave me a great offer which I immediately accepted.

So tomorrow, is the day that I am going to walk into my current boss and say that I will quit. My last day will be on Christmas day. And I will start my new year with a few weeks off, and then back to the job that I actually loved.

Life is to short to work with something you hate.

So I was looking at the linux environment at my new job. Found 2 VM's in the local network, only one of them is documented. Noone knows about the other one or what it does, let alone usernames and passwords.

Spent over an hour trying to break in, only to find out that a couple of bored devs, that have long since left the company, set up a game server on there and noone noticed it for the past 3 years..

Before anyone starts going batshit crazy, this is NOT a windows hate post. Just a funny experience imo.

So I was tasked with installing ProxMox on a dedicated server at my last internship. The windows admin was my guider (he could also do debian). (he was a really nice/chill guy)

So we were discussing what VM's we wanted and the boss (really cool dude by the way) said he wanted a VPS for storing some company stuff as well. Fair enough, what would we use? I suggested debian and centos. Then we started discussing what we'd do if the systems would fuck up etc (at installation or whatever).
So I didn't wanna look like a Linux Nazi so I suggested windows. Then the happy/positive guider/windows admin suddenly became dead serious (I was actually like 'woah' for a second) and said this:
No. We're not going to fucking use windows for this. For general servers etc sometimes, fair enough but we're talking about sensitive company data here. I don't want that data to be stored on a proprietary/closed source system, hell what if there's some kinda fucking backdoor build in, who can fucking verify that? We're using Linux, end of discussion.

😓

I was pretty flabbergasted as he's a nice guy and actually really likes windows!

Linux it became.

This rant is particularly directed at web designers, front-end developers. If you match that, please do take a few minutes to read it, and read it once again.

Web 2.0. It's something that I hate. Particularly because the directive amongst webdesigners seems to be "client has plenty of resources anyway, and if they don't, they'll buy more anyway". I'd like to debunk that with an analogy that I've been thinking about for a while.

I've got one server in my home, with 8GB of RAM, 4 cores and ~4TB of storage. On it I'm running Proxmox, which is currently using about 4GB of RAM for about a dozen VM's and LXC containers. The VM's take the most RAM by far, while the LXC's are just glorified chroots (which nonetheless I find very intriguing due to their ability to run unprivileged). Average LXC takes just 60MB RAM, the amount for an init, the shell and the service(s) running in this LXC. Just like a chroot, but better.

On that host I expect to be able to run about 20-30 guests at this rate. On 4 cores and 8GB RAM. More extensive migration to LXC will improve this number over time. However, I'd like to go further. Once I've been able to build a Linux which was just a kernel and busybox, backed by the musl C library. The thing consumed only 13MB of RAM, which was a VM with its whole 13MB of RAM consumption being dedicated entirely to the kernel. I could probably optimize it further with modularization, but at the time I didn't due to its experimental nature. On a chroot, the kernel of the host is used, meaning that said setup in a chroot would border near the kB's of RAM consumption. The busybox shell would be its most important RAM consumer, which is negligible.

I don't want to settle with 20-30 VM's. I want to settle with hundreds or even thousands of LXC's on 8GB of RAM, as I've seen first-hand with my own builds that it's possible. That's something that's very important in webdesign. Browsers aren't all that different. More often than not, your website will share its resources with about 50-100 other tabs, because users forget to close their old tabs, are power users, looking things up on Stack Overflow, or whatever. Therefore that 8GB of RAM now reduces itself to about 80MB only. And then you've got modern web browsers which allocate their own process for each tab (at a certain amount, it seems to be limited at about 20-30 processes, but still).. and all of its memory required to render yours is duplicated into your designated 80MB. Let's say that 10MB is available for the website at most. This is a very liberal amount for a webserver to deal with per request, so let's stick with that, although in reality it'd probably be less.

10MB, the available RAM for the website you're trying to show. Of course, the total RAM of the user is comparatively huge, but your own chunk is much smaller than that. Optimization is key. Does your website really need that amount? In third-world countries where the internet bandwidth is still in the order of kB/s, 10MB is *very* liberal. Back in 2014 when I got into technology and webdesign, there was this rule of thumb that 7 seconds is usually when visitors click away. That'd translate into.. let's say, 10kB/s for third-world countries? 7 seconds makes that 70kB of available network bandwidth.

Web 2.0, taking 30+ seconds to load a web page, even on a broadband connection? Totally ridiculous. Make your website as fast as it can be, after all you're playing along with 50-100 other tabs. The faster, the better. The more lightweight, the better. If at all possible, please pursue this goal and make the Web a better place. Efficiency matters.

Malware: "HAHAHAHAHA I HAVE HOSED YOUR PC AND REPLACED THE MBR! ONLY I REMAIN!"
me, loading my VM's clean slate snapshot:

Attempting to access my colleague's NFS directory on his VM, don't know the VM's IP address, hostname or password:

- 2 minutes with nmap to narrow the possible IPs down to ~30

- Ping each and look for the one with a Dell MAC prefix as the rest of us have been upgraded to Lenovo. Find 2 of these, one for the host and one for the virtual machine.

- Try to SSH to each, the one accepting a connection is the Linux VM

- Attempt login as root with the default password, no dice. Decide it's a lost cause.

- Go to get a cup of tea, walk past his desk.

- PostIt note with his root password 😶

FYI this was all allowed by my manager as he had unpushed critical changes that we needed for the release that day.

Oh my god VMWare 15 finnaly added an aspect ratio lock for VM's!!!!!!

Only took how fucking long?!

Accidentally plugged external disk into usb2 instead of USB 3 didn't realise till half way through 60GB VM's copy.

Oh don't worry I just wasted a whole day, it's not like I had homework to do, projects to finish and VM's to install and I busted my sick ass trying to make it all work on my Linux machine which is now tainted with software I didn't even want to install and useless docs while having a 105 fever. It's all fucking worth it because at the end, of the next day, oh wait...you didn't even install the updates properly, fuck you windows! I swear the first thing I'll do after graduation will be getting rid of you!!

Man I love VM's!

I'm on a very tight deadline and my laptop died this morning and needs a reformat, usually this would be a very dire situation... Luckily I use a virtual machine for my dev env so I just remoted into a pc at my office using my phone, launched an instance of my vm and forwarded a public IP to it.

I'm currently working on my rasberry pi while machines installing linux. The only noticeable difference so far is that I only have enough ram to keep open around 5 browser tabs. :-D

funny coincidence happened at work the other day.
One dev ask to get more ram for his pc so we sent him a link to download more ram... after all the laughs we actually gave hom more ram.
The next day, we had performance issue on our dev servers, and after checking the VM's where missing 4gb of ram each from the original setup... so i poke my dev and say see now we know where the downloaded ram came from XD. man those small things really make my day

I fucking hate Dockers for windows because you have to run hyper- v for Dockers to work and that kills the ability to use 64 bit vm's in virtual box.

WTF !!!!

!Rant

The Eve V is a Community Developed Windows Tablet which will be released in Ocotober this year.

The best specs you can get is i7 6th Gen, 16 GB Ram and 500 GB SSD for around 1400$.

He wants 32 GB RAM in such a slim and small Tablet. Also wants a 7th Gen Intel CPU and 1 TB SSD in it. He's ready to pay 1000 $ more for his special edition.

The Eve V is already finished with tooling and they are wating for the screens to arrive. They already have all the other parts.

Dude you're crazy and that specs just for VM's? What are you running? 10x WinShitBox?

He's insulting everyone on the forum with a different opinion and says, retooling will be such easy.

That guy is a real douchebag and doesn't know shit. If you would build in different parts like this, you would need to remodel the whole tablet. You can stick your 1000$ in your ass, retooling would cost more than 10'000$

If it's so easy you shithead, then do it yourself and dont say it's possible and say to other people they should do! 😂😂

How many other cheapskates are still using just HDD'S in their systems with plans to upgrade at least the os drive to an ass 'someday'

My laptop has a 1tb 5400rpm
My desktop has
A 500gb 7200 rpm OS drive
A 3tb 5400 rpm 'everything' drive and
A 1tb 5400 rpm 'testing' drive for VM's or programs I'm just toying with

So I spent over 200 hours recovering a raid array because the the business that hired the company I work for tried to do all the work in house. Now I'm to the point of trying to quote a new server setup to the company because the last one got hit by lightning. My quote $8000-$20000 in just hardware alone. If im going to do this I want to do it right. Twin servers running xenserver holding virtual machines with a high-quality Nas to hold the virtual machine. Then have the vm's being imaged to two off site backup devices in two different locations and a cloud backup. My boss comes in after me talks to the guy in charge and tells him all that is needed is one server holding all storage on it just like the last server that died and one off-site backup for $4500. How stupid can someone be who has been doing this for over 20 years? Oh btw the software running on this server will be 911 dispatch, jail records and the database for fine payments. The sheriff making the final call me and my boss are meeting with him tomorrow if my boss tries to undercut me I'm going to tell them both that if the same shit happens next time they can spend the time themselves trying to recover stuff because I done the over 200 hours in just short of two weeks.

Not owning a mac really does make mac exports really hard to test when you can only run a VM with 128MB of VRAM...

Who would have thought!

Took me an couple of days to reach this moment :')

Using MAAS to deploy to VM's, now time to get introduced to JuJu and see where it takes me :)

Ladies, gentlemen and fellow Aussie ranters....

Today is the day, I finnaly admit defeat on running GMS2 on a Linux distro...

Depsite the use of multiple wine version, swapping between 32 and 64 bit installations, throwing mono in as well as attempting with .NET core, even with all of the above at once (Don't ask).

With many hours behind me and many... many... many broken installs and dead VM's, I am admitting defeat.

The war between me and wanting to use a product I paid for where ever I wanted has come to an end and I am the only casualty in this war.

*Salutes and the last post starts playing in the distance*

FUCK YOU FUCKING AZURE FUCKING FUNCTIONS:

EITHER LIMIT MY NUMBER OF TCP CONNECTIONS (before violently crashing)

or

FORCE ME TO USE THE GODDAMN PORT-PISSING, BARELY-MULTITHREAD-USABLE, SETTINGS-IGNORING EXCUSE OF A PATHETIC BUILT-IN HTTPCLIENT ON FUCKING CRACK (Seriously .net people fix that shit).

But not both... both are not okay!

If your azure function just moderately uses outgoing Http requests you will inevitably be fucked up by the dreaded connection exhaustion error. ESPECIALLY if using consumption plans.

I Swear, every day i am that much closer to permanently swearing off everything cloud based in favor of VM's (OH BUT THEN YOU HAVE TO MAINTAIN THE VM's BOO HOO, I HAVE TO BABYSIT THE GODDAMN CLOUD INFRASTRUCTURE AS WELL AT LEAST I CAN LOG IN TO A VM TO FIX SHIT, fuck that noise)

I am in my happy place today. At least I'm having great success diving into minecraft modding on the side, that shit is FUN!

Warning long rambling story cause sleep deprivation

I never really bothered with ssh outside of using putty to remote into my servers and rpi's from my desktop to run updates, install something, or whatever else.

But today I was on a call with my cousin bored cause she was just rambling, so I opened vscode to clean my install of unnecessary extensions I installed and haven't used more than once or twice.

I saw Remote - SSH and as I was bored listening to a teenager complain about high school just like I used to (lol) and responding when she asked me something. I scrolled through the page, then the documentation just casually skimming the text

I setup an ssh key on an rpi I threw manjaro arm following the instructions on their tips and tricks page
I then moved the key to my desktop using winscp (cause lazy)
leading to having a minor hicup of rsa not being an accepted keytype (thanks 'your favorite search engine' for the help)
Finally, I was able to connect using the private key

at this point my cousin went to bed cause she has school tomorrow. But I was still doing stuff with ssh, I created a new ssh connection in VSCode, but had to go to the documentation to figure out how to make it use my fancy new key file, not hard took 30 seconds of looking to get it working.

Now that I was in, I moved to my development folder, created a folder for PiHole, created a compose yml, created a pihole-data folder.
I opened the yml and pasted in a compose from dockerhub.

at this point I thought 'i can't just run this from terminal can I'. and Obviously it worked cause there's literally no reason it wouldn't I'm just stupid to think it might not.

So I created folders and files on a remote system, launched a docker container, checked for package updates after on a linux machine. All from VS-Code on a windows machine.

I know this is simple for some people, i know some people are like 'where's the interesting part'. but ehhh I thought it was cool to get it setup, I now really regret not getting into ssh sooner, and I'm definitely going to uninstall vscode on all my smaller graphical VM's in favor of doing this. and this will definitely help with my headless vm's.

I also will have to thank my cousin, might not have done this if I wasn't stuck at my computer on messenger call with her lol

I'm gonna go to bed now, But I feel accomplished for the first time in a while even if it's for something so simple as setting up anssh key for the first time

So apparently vmware has a blacklist of video drivers... if you want to ignore the blacklist you legit have to manually add a line to the .vmx file...

I understand it's not a massive problem everyone will have but at least add a GUI option...

Fuck me, if your going to have something that can potentially render your product useless to some users out of the box, at least give them a simple way, even if it is just under he VM's advanced options -.-

So just sitting here watching my windows VM's cpu usage to monitor was seems to be causing some stuttering and then out of fucking nowhere the default photo's app pops and and claims 96% of the CPU...

I understand computers are weird but how the hell does an app randomly start and jump to such a high CPU usage?

So, most (if not all) modern operating systems sync their time with some trusted source (like the Internet) right? Windows included. All is well.

When your Windows 10 computers are joined to a domain, it thence relies on your local neighborhood domain controller to tell it the time. Sounds good, since domain controllers Never Go Down, right? All is well.

Services are all being cloud-ified, which means virtual machines. The domain controllers have suffered this fate, but everything is smooth and buttery. All is well.

Wait, the VM's clock is running slow. Uh oh....
Wait, isn't it supposed to ask the Internet?
Well, no. Domain Controllers decide that They Know All, and stop asking the Internet for its opinion.

This causes problems, but only ever so slowly, and it took me noticing all the computers seemed to be ten minutes slow compared to my phone (and well everyone else's phone) to realize what had happened.

Thanks, Windows...

Trying to setup a staging server boss says just use AWS, system admin doesn't like that thought because it doesn't involve him so waited all day for 3 VM's and still not ready... All I need is 3 blank CoreOS VMs nothing fancy like even doing the cloud config no. Anyone else has colleagues scared of moving out of the private high maintenance servers in the basement?

You know you're bored when you are recreating random Linux distributions in arch Linux VM's...

Yo, have some questions for all you Macbook devs here.
#0. What language do you mostly write in?
#1. Do any of you dualboot / use VM's on your Mac?
#2. Is it better or worse (in your experience) to code on a Macbook in general?

Asking bc Im thinking on getting one for The thin and lightness of it.

You know your night is off to a great start when it takes you 30 minutes to remember VM's exist and can be really good for testing out display scaling... Well done Alex... Well done

Most fun I had coding?

I was developing my first android app and the database accounted for all the weekdays.

It was a night and I was coding. I build the app after 90 minutes of last build. I was fucking amazed to see that my app was running perfectly on Genymotion Emulator whilst the same god damn build crashed on my phone.

As a new novice developer, I thought it could be due to the OS version difference b/w my phone and VB.

I went on to spent an hour or so, to figure out where I had gone wrong. I re-read my code multiple times and nothing. I could not find a single error in the code.

I was fucking speachless when it hit me, FUCK, today is Saturday (last build was around 11PM Friday) and VM's time is usually screwed (it was Wednesday there) and since I had not accounted for weedends entry in database, the app crashed.

It was really fun having this sort of a bug for the first time in my life. Solved it within minutes after that.

What do you think of my setup?
I carry a strong laptop for heavy lifting and an iPad for RDP'ing into either my laptop or cloud hosted VM's.
This setup is obviously optimized for mobility, if I had a stable place to work, I'd use a desktop with multiple screens.

Our clients VM is so slow it is trying to give me schizophrenia. Any way I can get around it and work on my company laptop itself?

How do you guys separate your working environments for different projects?

My situation is that I have one gaming project which requires having Windows OS (for testing purposes since can't run that game on Linux or Mac OS)

Then I have 2-3 other projects (freelancing/fulltime gigs) which don't require Windows so I use macbook for them.

Then I have other projects for my freetime (self development and stuff) and also need an environment just to be able not to work and chill instead

I tried separating these concerns with using tools such as evernote, trello and etc. but it's really getting out of hand.

Using different users for Win/Mac is not an option since I dont want to be switching between different users all the time.

Should I consider using some VM's to have my working environments for different projects separate? Will I use performance when using these VM's?

Buying 5 laptops just to separate everything doesnt make sense as well.

How can people stand this bitten apple? With this mojave update I now feel in the most unfriendly desert for developers.
Not only did your update render all my VM's unusable, but the new AppStore seems a joke. This new icon there if a piece is downloading or installing or whatever. I cannot tell what it should tell me. That an alien took a crap on my display? There's no percentage, nothing indicating what's actually happening. Is this your understanding of user experience through obscurity? - shunning the user from any useful information, hiding everything behind some nice looking vapourware?

Just installed Cent OS 7 on my HP 380 g6 server, can someone please explain why hp withholds bios updates unless you pay extra... Where do I even get a support licence for this old thing. DoD normally handle's these things.

Also what do you do with a server at home. I found some AI assistant software to run and of course VM's but what else.

First week at the University, i became a circular mail with an offer for a place in the webteam. Requirements were a basic knowledge in linux/ubuntu and its packagemanagement and also some minor basics with nginx.
one day later i decides to mail my interest and that i mostly self-taughted me using linux since some years and began programinga year ago with python and recently deployed my first project in a VPS with nginx.
either, my qualification is quite high for that job or i was the one and only applicant, but who cares, i'm in.

this is my first employment in the it area,so i'm quite exited, even its mostly an administrative position. i gonne administrate the vm's for some websites and a special portal for students.

but! due to the fusion of two faculties at my university, there will also be two websites to be merged( our is on zope/plone and the other is a typo3) (computer science vs media... no really^^

well, now i have to wait for the doodle for the first meeting

So the first 3 hours at work on a Monday have been spent giving technical support to fellow co-workers on THEIR OWN local development environment. I have no idea how they've set everything up but they want me to fix their VM's.

System76 laptops good? Considering getting one to gracefully migrate fully away from windows since I'm basically in wsl and Linux vm's most of my day these past few months anyway
