"You gave us bad code! We ran it and now production is DOWN! Join this bridgeline now and help us fix this!"
So, as the author of the code in question, I join the bridge... And what happens next, I will simply never forget.
First, a little backstory... Another team within our company needed some vendor client software installed and maintained across the enterprise. Multiple OSes (Linux, AIX, Solaris, HPUX, etc.), so packaging and consistent update methods were a a challenge. I wrote an entire set of utilities to install, update and generally maintain the software; intending all the time that this other team would eventually own the process and code. With this in mind, I wrote extensive documentation, and conducted a formal turnover / training season with the other team.
So, fast forward to when the other team now owns my code, has been trained on how to use it, including (perhaps most importantly) how to send out updates when the vendor released upgrades to the agent software.
Now, this other team had the responsibility of releasing their first update since I gave them the process. Very simple upgrade process, already fully automated. What could have gone so horribly wrong? Did something the vendor supplied break their client?
I asked for the log files from the upgrade process. They sent them, and they looked... wrong. Very, very wrong.
Did you run the code I gave you to do this update?
"Yes, your code is broken - fix it! Production is down! Rabble, rabble, rabble!"
So, I go into our code management tool and review the _actual_ script they ran. Sure enough, it is my code... But something is very wrong.
More than 2/3rds of my code... has been commented out. The code is "there"... but has been commented out so it is not being executed. WT-actual-F?!
I question this on the bridge line. Silence. I insist someone explain what is going on. Is this a joke? Is this some kind of work version of candid camera?
Finally someone breaks the silence and explains.
And this, my friends, is the part I will never forget.
"We wanted to look through your code before we ran the update. When we looked at it, there was some stuff we didn't understand, so we commented that stuff out."
You... you didn't... understand... my some of the code... so you... you didn't ask me about it... you didn't try to actually figure out what it did... you... commented it OUT?!
"Right, we figured it was better to only run the parts we understood... But now we ran it and everything is broken and you need to fix your code."
I cannot repeat the things I said next, even here on devRant. Let's just say that call did not go well.
So, lesson learned? If you don't know what some code does? Just comment that shit out. Then blame the original author when it doesn't work.
You just cannot make this kind of stuff up.105 -
The programmer and the interns part 2.
We will discuss numerous events that happened over the past week or so.
Case 0:
We had our weekly engineering meeting. The interns were invited as well.
We hold meetings in the generic, big, corporate meeting rooms with a huge table in the middle.
There were more than enough chairs for everyone yet the most motivated and awkward intern (let's call him Simon) chose to stand, cause "it's cool man, I always stand". At this point we all know that he probably read about Agile stand up meetings and is confusing it with this one. Otherwise he's simply trying to stand out from the rest. (See what I did there?)
Anyway the meeting has started way later than planned (what a surprise) and took much longer than Simon expected. Everybody is sitting and listening to the CTO while occasionally glancing at the weird looking intern standing awkwardly and refusing to sit because it would make his original intentions pointless. He even tried to nod whith a serious face and his hands crossed when the CTO said something and looked at his general direction. The meeting was about a hour and a half long but with the delay it was at least 2.5 hours.
At the end Simon was so exhausted that he fell asleep on the office puff, was forgotten and locked inside. 3 hours later when I was home I received a call from him with his sleepy-trying-to-sound-awake voice telling the news. Lucky there's a 24/7 Noc team that could rescue him.
Case 1:
An intern who was late on his Linux test connected to every test VM (should I remind you that each one has a personal VM but they share passwords for their roots?) and tried to reset it with "sleep 10s; shutdown -h now".
He took down all 13 of those so I had to turn them on and switch passwords again.
Case 2:
One of the interns didn't do any of his training chores. Apparently he forgot what he was told to use, ignored all online documentation and used Windows CMD with Linux commands for almost a week already.
Case 3:
Simon uses Vim to write all text possible. Even mails, he then selects all and copies into the mail body. He spent half a day on a homework task I gave them. He wrote everything inside one text file using Vim. When he was done he saved the file and quit the editor. He then said "Oh shit! I've forgot to sign my name!". I explicitly told him that theres absolutely no need for that because I see which mail the file was sent from. He said "I don't even need a program for that!" and gave a couple of strokes on the keyboard.
Later I received an email from him with a .txt attachment. When I opened it the only text that was inside was "by Simon ;)".
I logged to his machine and checked the last command ran on the file:
echo "by Simon ;)" > linuxtasks.txt
Case 4:
The girl here uses a MacBook. She keeps getting confused with the terminal windows and rebooting her own machine instead of the remote VM.
Case 5:
Haven't checked yet how this happened but one of the interns deleted the gui from his local Centos.33 -
One comment from @Fast-Nop made me remember something I had promised myself not to. Specifically the USB thing.
So there I was, Lieutenant Jr at a warship (not the one my previous rants refer to), my main duties as navigation officer, and secondary (and unofficial) tech support and all-around "computer guy".
Those of you who don't know what horrors this demonic brand pertains to, I envy you. But I digress. In the ship, we had Ethernet cabling and switches, but no DHCP, no server, not a thing. My proposition was shot down by the CO within 2 minutes. Yet, we had a curious "network". As my fellow... colleagues had invented, we had something akin to token ring, but instead of tokens, we had low-rank personnel running around with USB sticks, and as for "rings", well, anyone could snatch up a USB-carrier and load his data and instructions to the "token". What on earth could go wrong with that system?
What indeed.
We got 1 USB infected with a malware from a nearby ship - I still don't know how. Said malware did the following observable actions(yes, I did some malware analysis - As I said before, I am not paid enough):
- Move the contents on any writeable media to a folder with empty (or space) name on that medium. Windows didn't show that folder, so it became "invisible" - linux/mac showed it just fine
- It created a shortcut on the root folder of said medium, right to the malware. Executing the shortcut executed the malware and opened a new window with the "hidden" folder.
Childishly simple, right? If only you knew. If only you knew the horrors, the loss of faith in humanity (which is really bad when you have access to munitions, explosives and heavy weaponry).
People executed the malware ON PURPOSE. Some actually DISABLED their AV to "access their files". I ran amok for an entire WEEK to try to keep this contained. But... I underestimated the USB-token-ring-whatever protocol's speed and the strength of a user's stupidity. PCs that I cleaned got infected AGAIN within HOURS.
I had to address the CO to order total shutdown, USB and PC turnover to me. I spent the most fun weekend cleaning 20-30 PCs and 9 USBs. What fun!
What fun, morons. Now I'll have nightmares of those days again.9 -
This rant means YOU if you are one of those people that "fix" their family's computers.
I was visiting my family over the holidays and while I managed to stay away from fixing their computers for the most time, I offered to help my grandfather to update the Garmin navigation device he wanted to gift my father. (They do not use smartphones for navigation, and my father doesn't want "these modern shitty phones".)
When booting up my grandfather's laptop, I realized something odd: Linux Mint boot screen. Wut?
And immediately I said: "It could be impossible to update your navigation device on this laptop."
As true enough, the Garmin Express update software requires either a Windows PC or a Mac; and even though I vaguely hoped it might be possible to upgrade through Linux, I just could not be bothered to find out that day.
What I wondered though is why did my grandfather of all people ran Linux!?
Don't get me wrong, I use Linux myself on my work machine and I never want to work with something else when coding; yet my grandfather is an end user of the show-me-where-and-what-and-how-often-to-click-kind.
What could he gain by it?
As it turns out, the computer nerd's friend of my uncle managed his PC. And my uncle and he decided unanimously my grandfather should better run Linux. Is it something my grandfather needs? No. BUT IT'S RIGHT! Suck it up! (My father's laptop therefore also runs Linux Mint. So he can't upgrade his new device either.)
This is the ugly kind of entitled nerd-dom I truly detest.
When discussing things further, my grandfather told me that he had problems ever since with his printer. Under Windows, he knew how to print on the special photo paper. Under Linux, all he can barely manage is to print on normal papers. Shame, printing photos was the only thing he liked doing on that device. What did my uncle's friend tell him?
"Get a decent printer!"
Fuck that guy.
It's fine if Linux works for you, but before you install it on a PC of a relative, you better make sure it fits their needs! If you have that odd member that only wants to write letters, read emails, use facebook, and wants to play that browser game, feel free to introduce them to Linux.
Yet if they have any special wish, don't stand in their way.
If they want to do something that requires a certain OS, don't just decide for them that their desire is wrong, but help them achieve their goal. If you can't align that with your ideology, then get the fuck out of my way and stop "helping".
For some people, a computer is a device to achieve a certain goal, a work. They only get hindered by your ill-advised attempts at virtue signalling.9 -
Continuation of the story with Linux Mint 20 Cinnamon on the old Core2 Duo with 2 GB RAM and HDD. The guy has had that PC under Linux for 1.5 months now, had never had Linux before, has no IT background, and is over 70.
Upon visit, I checked how the machine was doing. OK, he had forgotten to apply the updates, so I highlighted paying attention to the red icon in the tray. Launched the updates, all ran through.
Otherwise, he had managed to install Skype all by himself (network effect because of his family...) and had bought a webcam plus a microphone. Linux had just recognised everything without any fuzz. Even his Skype buddies were impressed, he said.
On top of that, he likes how much faster that PC is compared to his much more current Win 10 laptop and actually uses the old Linux PC more than the laptop.
He also enjoys that Linux doesn't do weird things all by itself all the time. That's not his experience with Win 10.12 -
When I was young I'd play games and around age 11 received an Xbox for my bday. Hated the case, so I painted the case. Since I had it open looked into getting a replacement fan.Thats when everything changed. I discovered the modding scene and without having any computer background/literacy got to studying.
The program that caught my eye ran on Linux. *shrugs thinking how hard can it be? * Read about Linux and discover dual booting. To do that I needed to resize windows partition. Learn more about partitions and get to it. Finally prepped... Backup in case of the worst, resized windows partition, working Ubuntu bootable USB, and printed install tutorial. Check, check, and check. Install was good. Sort of.
While Ubuntu worked, the broadcam wireless chipset driver did not. Fast forward a week and I feel that i had mastered the terminal basics. And WiFi worked! Go download the aforementioned program and FTP into the Xbox and BOOM... It doesn't work. More days and hours spent researching. In the end it all chalked up to not setting a static IP address on Xbox.
After all was said and done I had a bitchin Xbox. I think the only thing I didn't put on it was some gold spinning rims.
Sad part about that Xbox is that I never used it after. Instead I just kept messing around with Linux and learning more about computers. Taught myself HTML/CSS. Learned more about shell scripting. Then Windows cmd basics. Tried programming languages but felt a little overwhelmed. Only messed with <10 lines of code to tweak existing programs.
Now I'm learning C# and loving it. Planning on C++ or Java next! -
This is the single most important question of the year:
Where is a good Minecraft server service that can run FTB Modpacks?
My options are:
1 - A dedicated linux box with Minecraft management software with a port open to the world.
2 - Purchase a vps or something similar to host MC.
I have done 1, and it worked pretty well. It ran on a tiny A8 processor with 8GB ram and an SSD. I see services and they cost like 15 to 20 a month and seem like they are awfully stingy on storage. I can get an enterprise server for 30 a month, but I just asked (my webhost, who I really like) and they said they cannot run Minecraft servers. They said I would need a vps, and they don't have them yet. So I could dig around for a vps service and that is an option. I am really wary of "minecraft" branded services as many are outright ripoffs.
Thoughts? Successes? Just do it myself?5 -
Making a hard switch to ubuntu on my desktop at home. Getting just a teeny tiny, tad, bit: absolutely fucking livid....
Trying to learn ansible, vagrant, and docker more in depth for both work and my personal projects. All that I’ve been doing is just spinning my wheels trying to figure out the stupid fuck-mothering quirks with running this shit on Windows. Yes you absolutely can use all of these tools on a Windows box. There’s plenty of ports, patches, and workarounds. But I have spent all day trying to build a few vagrant boxes and use ansible to set them up. Simple LAMP stack boxes on CentOS7. Nothing major... unfortunately I spent like 90-110 minutes trying to figure out why virtualbox wouldn’t run properly. Dumbass me forgot that I installed Hyper-V ages ago.
O...K.... whelp... hyperv provider it is...
Luckily it only took about 15 minutes to determine that Hyperv’s networking can’t be setup from vagrant because vagrant doesn’t know how to interact with the hyperv - vswitch. So networking config is ignored and all VMs run on default switch (NAT) which is annoying but workable.
Ran into other issues trying to stay SSH’ed into the VM. PowerShell core (6) ssh’es into the box perfectly fine, but every time I opened vi to edit configs my terminal color scheme and fonts got fucked harder than a 2 dollar hooker on nickel night.
I’m a bright-green text on black background kinda guy. However the terminal kept changing to bright-red text on white background! It was like getting skull-fucked by a minotaur.
After a while I said fuck it, let’s try putty. Vagrant was using it’s own ssh keypair for the boxes, at work on my mac. Works like a dream. Putty failed me hard and shit the bed, kept getting all kinds of keypair errors. At this point I was finished spent too long trying to make shit work correctly on this jankbox. With enough time and patience I probably could’ve figured all of these problems out. I’m certain that at least 70% of them were caused by user error. I’m known by many as the walking ID-10t.
But alas, I have no time left in the day to fuck around with shit that doesn’t work immediately for morons like myself. My only hang up for the longest time with a complete switch to Linux was gaming. But with Proton and WINE I’m comfortable with giving it the ol’ college try. (Shhhh, don’t remind me I dropped out of college...
...Thrice.)
The gamble here is that I’ll give more than 2 halves of a fuck about trying to get my games working. A Study environment and materials for certs and general training won’t be getting anywhere near my full attention.
So, at long last, I hope this attempt at a full *nix switch finally sticks!!!

Just seen F# and really like it. Sadly its compiler throws all kinds of errors on Linux with Mono because for some stupid reason it uses the Mono 2.0 DLLs...undefined lots of debugging tomorrow whyyy it said that it ran on linux all will be functions hail functional programming
