Hello everyone, this is my first time here so hi! I want to tell you all a story about my current situation.
At 18 while in the military I was able to get my first computer, it was a small hp pavilion laptop with windows 7. The system would crash constantly, even though I would only use it for googling stuff and using fb to talk to people. 5 months after I got it and continuously hated it decided to find out why and who could I blame (other than myself) for the system making me do the ctrl alt del dance all the time....
Found out that there are people called computer programmers that made software. Decided to give it a go since I had some free time most days. Started out with c++ because it was being recommended in some websites. Had many "oh deeeeer lord" moments. After not getting much traction I decided to move to Java which seemed like an easier step than C++. Had fun, but after some verbosity I decided to move into more dynamic lands. Tried JS and since at the time there was no Node and I was not very into the idea of building websites I decided to move into Python, Ruby, PHP and Perl and had a really great time using and learning all of them. I decided to get good in theoretical aspects of computer programming and since I had a knack for math I decided to get started with basic computer science concepts.
I absolutely frigging loved it. And not only that, but learning new things became an obsession, the kind that would make me go to bed at 02:40 am just to wake up at 04:00 or 06:00 because the military is like that. I really wanted to absorb as much as I could since I wanted to go to college for it and wanted to be prepared since I did not wanted to be a complete newb. Took Harvard CS50, Standford Programming 101 with Java, Rice's Python course and MIT's Python programming class. I had so much fun I don't regret it one bit.
By the time I got to college I had already made the jump to Linux and was an adept Arch user, Its not that it was superior or anything, but it really forced me to learn about Linux and working around a terminal and the internals of the system to get what I want. Now a days I settle for Fedora or Debian based systems since they are easier and time is money.
Uni was a breeze, math was fun and the programming classes seemed like glorified "Hello World" courses. I had fun, but not that much fun, most of my time was spent getting better at actual coding. I am no genius, nor my grades were super amazing(I did graduate with honors though) but I had fun, which never really happened in school before that.
While in school I took my first programming gig! It was in ASP.NET MVC, we were using C#, I got the job through a customer that I met at work, I was working in retail during the time and absolutely hated it. I remember being so excited with the gig, I got to meet other developers! Where I am from there aren't that many and most of them are very specialized, so they only get concerned with certain aspects of coding (e.g VBA developers.....) and that is until I met the lead dev. He was by far one of the biggest assholes I had ever met in my life. Absolutely nothing that I would do or say made hem not be a dick. My code was steady, but I would find bugs of incomplete stuff that he would do, whenever I would fix it he would belittle me and constantly remind me of my position as a "junior dev" in the company saying things as "if you have an issue with my code or standards tell me, but do not touch the code" which was funny considering that I would not be able to advance without those fixes. I quit not even 3 months latter because I could not stand the dick, neither 2 of the other developers since the immediately resigned after they got their own courage.
A year latter I was able to find myself another gig. I was hesitant for a moment since it was another remote position in which I had already had a crappy experience. Boy this one was bad. To be fair, this was on me since I had to get good with Lumen after only having some exposure to Laravel. Which I did mentioned repeatedly even though he did offer to train me in order to help him. Same thing, after a couple of weeks of being told how much I did not know I decided to get out.
That is 2 strikes.
So I waited a little while and took a position inside another company that was using vanilla PHP to build their services. Their system was solid though, the lead engineer remains a friend and I did learn a lot from him. I got contracted because they were looking for a Java developer. The salary was good. But when I got there they mentioned that they wanted a developer in Java...to build Android. At the time I was using Java with Spring so I though "well how hard can this be! I already use Android so the love for the system is there, lets do this!" And it was an intense, fun and really amazing experience.
-- To be continued.10 -
I was engaged as a contractor to help a major bank convert its servers from physical to virtual. It was 2010, when virtual was starting to eclipse physical. The consulting firm the bank hired to oversee the project had already decided that the conversions would be performed by a piece of software made by another company with whom the consulting firm was in bed.
I was brought in as a Linux expert, and told to, "make it work." The selected software, I found out without a lot of effort or exposure, eats shit. With whip cream. Part of the plan was to, "right-size" filesystems down to new desired sizes, and we found out that was one of the many things it could not do. Also, it required root SSH access to the server being converted. Just garbage.
I was very frustrated by the imposition of this terrible software, and started to butt heads with the consulting firm's project manager assigned to our team. Finally, during project planning meetings, I put together a P2V solution made with a customized Linux Rescue CD, perl, rsync, and LVM.
The selected software took about 45 minutes to do an initial conversion to the VM, and about 25 minutes to do a subsequent sync, which was part of the plan, for the final sync before cutover.
The tool I built took about 5 minutes to do the initial conversion, and about 30-45 seconds to do the final sync, and was able to satisfy every business requirement the selected software was unable to meet, and about which the consultants just shrugged.
The project manager got wind of this, and tried to get them to release my contract. He told management what I had built, against his instructions. They did not release my contract. They hired more people and assigned them to me to help build this tool.
They traveled to me and we refined it down to a simple portable ISO that remained in use as the default method for Linux for years after I left.
Fast forward to 2015. I'm interviewing for the position I have now, and one of the guys on the tech screen call says he worked for the same bank later and used that tool I wrote, and loved it. I think it was his endorsement that pushed me over and got me an offer for $15K more than I asked for.4 -
My worst experience was at my job where they told me I have to move to a permanent position from 3 years of contracting without a specific offer.
Why is that bad? In my country it means approximatly 40% lower wage.
I came into the job with PHP knowledge when they were looking for Perl on a project one year behind schedule. I learned the language and finished working demo in 6 weeks.
After that, every project that was ever assigned to me was done within 5-15% of the allocated time. I'm not kidding here. My manager loved be, because I was reliable, fast and I even 'accidentaly' solved other problems, like for instance I developed simple syslog search tool and benchmarked zip algos for reading speed, and the fastest had 70% better compression than the algo used before (gzip into plzip on 1-2gb files). That solved anothet problem - syslog servers did not have enough disk space and they didn't have money to upgrade the server.
The number of projects I touched or developed was over 20.
I also lead and developed our team's most successful tool, that every customer was throwing money to buy, while cutting down costs everywhere.
And after three years of that, my manager says that there are no more money for contractors. And the only possibility is going for employment. Without any specific offer! Just 'we cant do this anymore'.
Which I understand, that can happen in corporation, but ffs after all I've done, I expected warmer attitude. Not like 'you may have to leave, since we do not really care'.
I liked the people there, even though the corporation environment was lacking in many respects, but I wanted to help our local branch with everything I could and they gave up on me like that.
So I started looking elsewhere and I found a startup which offered 6 times the money I had in my previous job and promises to relocate me to USA. Which is the best thing that has happened to me that year and second best in my whole life!3 -
Worst exp. on a collab/group project?
Had a few, here is one.
Worked with a dev team (of two devs) in Norway to begin collaboration on providing a portal into our system (placing orders, retrieving customer info, inventory control, etc)
They spoke very good English, but motivation was the problem. Start the day around 10:00AM...take a two hour lunch...ended the day at, if I was lucky, 4:00PM (relative to Norway time). Response time to questions took days, sometimes weeks. We used Skype, which helped, but everything was "Yea...I'll do that tomorrow...waiting on X....I have a wedding to go to, so I'll finish my part next week."
I didn't care so much, I had other projects to do, but the stakeholders pounded me almost everyday demanding a progress report (why aren't you done yet...etc..etc.)
The badgering got so bad I told the project owner (a VP) if he wanted this project done by the end of the year, the company would have to fly me to Norway so I personally push things along.
When real money was on the line, he decided patience was warranted.
A 3 month project turned into 9, and during a phone meeting with the CEO in December
O: "Thanks guys, this project is going great. We'll talk again in February. Bye."
PM: "Whoa...what! February!"
<sounding puzzled>
O: "Um..yes? It's Christmas time. Don't you Americans take off for Christmas?"
PM: "Yes, but not until Christmas. Its only December 12th. Your taking the whole month of December and January for Christmas?"
O:"Yes, of course. You Americans work too hard. You should come over here and see how we celebrate. Takes about a month so we can ease back into the flow of things."
<Jack is the VP>
PM: "Jack wanted this project completed by the end of the year, that is what everyone agreed to."
O:"Yes, I suppose, but my plane is waiting on me. Not to worry, everything will be fine."
<ceo hangs up>
PM: "Oh shit..oh shit..oh shit. What are you going to do!?"
Me: "Me!?..not a darn thing. Better go talk with Jeff."
<Jeff is the VP>
J: "This is unacceptable. You promised this project would only take a few months. I told you there would be consequences for not meeting the deadline."
PM:"But..but...its not our fault."
J: "I don't care about fault. I care about responsibility. I've never had to fire anyone for not meeting a deadline, but .."
Me: "Jeff, they are in Norway and no one is working this project for the next two months. You've known for months about them dragging their asses on this project. We're ready to go. Services have been tested and deployed. Accounting has all the payment routing ready. Only piece missing is theirs."
J: "Oh. OK. Great job guys. I guess we'll delay this project until February."
<leave the office>
PM: "Holy shit I'm glad you were there. I thought I was fired."
Me: "Yea, and that prick would have done it not giving a crap that it's Christmas."
<fast forward to Feb>
O: "Our service provider fell through, so I'm hosting with another company. You guys know PHP? Perl? I don't know what they called it, but it sounded so cool I bought the company."
PM: "You bought what? Are we still working with Z and B?"
O:"Yea, sort of. How's your German? New guy only speaks German."
PM: "Um, uh... no one here speaks German"
O:"Not to worry, I speak German, French, and Italian. I'll be your translator."
PM: "What? French and Italian?"
O: "On my trip to France I connected with a importer who then got me in touch with international shipper in Italy. I flew over there and met a couple really smart guys than can help us out. My new guy only speaks German, J only speaks French, and R speaks Italian, Russian, and a little English. Not to worry, I'm full time on this project. You have my full attention."
We believe the CEO has/had some serious mental issues, including some ADD. He bailed within the first month (took another vacation to Sweden to do some fishing) and left me using Google Translate to coordinate the project. Luckily, by the end, the Norwegian company hired a contractor from England who spoke German and hobbled together the final integration.3 -
*gets annoyed by how vi command in Ubuntu WSL points to vim*
To be clear, that's due to update-alternatives in Ubuntu, not WSL specifically.
*le me ducking how to install vi instead, because vim in WSL has scrolling issues*
"install vi ubuntu"
> How do I install and get started with vim/vi? - Ask Ubuntu
> apt - Vim installation in Ubuntu 14.04 - Ask Ubuntu
> Ubuntu Linux: Install vim Text Editor - nixCraft
-.- I'm not looking for vim ffs, I already have that installed.
"install vi ubuntu -vim"
> Same fucking results
"!g install vi ubuntu -vim"
> Installing the VI Perl Toolkit from Source Code—Linux - VMware
> FedoraDirectoryServerClientHowto - Community Help Wiki - Ubuntu …
> Learn How To Use Linux vi Editor And Its Commands - LinOxide
Oh for fuck's sake!!!
So here's my question because apparently search engines clearly can't point me to it, and Ubuntu doesn't seem to have vi as "vi" in their repositories either. Do our Canonical overlords allow people to actually make /usr/bin/vi actually be fucking vi?11 -
I tried out Perl this year, really loved it. No one wanted to do a project with me in Perl though, so I moved on. Now I am doing my projects in javascript. I can't help but think that there is something very wrong with me for liking just the languages everyone hates with a passion. 🙃3

You want to change the wifi network to which is your embedded device connected?
It's easy:
- The native process is broken
- ESP is in the correct state, but refuse to communicate with anything
- Restore to default doesn't work
- Flashing default firmware doesn't help
- download the whole NodeJS/NPM
- compile two perl binaries
- bump into 2 year old bug, that your Intel wifi won't connect to the ESP SoftAP
- reinstall the Intel driver, just to find out it's still not fixed
- connect the external Atheros wifi adapter
- connect that shit back to the cloud
And just after little under 4 days of fiddling with GPIO pins it finally works and communicates.2 -
Did I ever mention how much I hate reading through perl scripts?
Seriously, I can read through BASH hell anyday, Python's fine, PHP... But out of all of the scripting languages, Perl is just something that makes me want to scratch my eyes out.
It doesn't help it used to be the sysadmin's language of choice in the past.
Perl just hurts my brain.5 -
I need to convert lots and lots of lengthy hard-coded entities into backend objects, as I'm tired of pushing new commits every time something superficial needs to change.
Also, I need to figure out continuous integration. The guy who was going to help with that just left the company, and I was using his eventual forthcoming help as an excuse not to take responsibility for learning about it myself.
I need to learn golang and start converting some code to it, to see if the performance compares to the perl that's currently in place. Perl is brilliant, but aside from me, only old people know it, at my office. That definitely creates a longterm supportability issue.2 -
Not specifially one but a couple of minor mentoring moments.
I started out at a rather small company (<10 people) with a completely new language to me (Perl).
I had some trouble following along some tasks since I wasn't familiar with Perl or generally backend stuffs at all.
So the person that was supposed to "mentor" me was just giving me tasks without any hints of how to do things, this is where my "true" mentor came in to play.
I asked him a couple of things after a few unsuccesful searches on the internet and he always seemed to have the answer to it right away! It seemed like he knew everything and I really appreciated his patience and help. He did point me in the right directions when I needed it.
He left the company about 3 months ago and I still somewhat miss his mentoring existance, as he wasn't only a code but also a life mentor.
I really hope that one day I can be just like that guy, helpful, patient and be a mentor for someone else. :) -
I know a lot of people aren't fans of Microsoft here, but does anyone have some extended experience with using powershell?
I've been using it for creating a script that handles quite a large set of tasks for setting up and configuring some application servers and so far I have been really digging the language. Being able to invoke the script against remote hosts in parallel like ansible has been a really cool learning experience.
Admittedly it's verbose as fuck, so getting the same thing done in something like python/perl might be like half the lines of code. And I know that some of the commands illicit a "WTF?" every now and again. But I think one of the powershell tutorials I watched early on in attempting this helped make using powershell not suck ass.
Every command is basically 'verb-noun'. You don't know what the command or switches are:
> get-help "command" -showwindow
It will give you a list of options if you didn't select the exact command with get-help.
It feels* amazingly buttoned up as a scripting language and it's really cool to be able to take advantage of lower level stuff, like you can run alternative shells (we have cygwin installed on some of our servers), you can run C# code, you have access to interfacing with .NET api's. I haven't messed with anything azure yet, but being able to interface with products and services like SQL/Exchange/O365/azure/servers/desktops from the same language seems pretty cool.
Admittedly, the learning curve feels terrible though. I felt like a dunce for the first couple weeks, couldn't navigate the language at all, and was always in the docs trying to figure stuff out. I think I just needed to understand how the people developing powershell intended for it to be used. Once I was able to put two-and-two together about the verb-noun structure and how to find information/examples about the cmdlets it's been quite easy to work with it.
If anyone else has any extended experience with it, please share your thoughts/opinions. Curious to see if your experiences are/were similar to mine.
If you don't have Powershell experience, please feel free to share your opinions of Micro$haft and me for using Micro$haft products too! It's all good 😎9 -
I was given a perl script to help change ubnt airos devices passwords from the command line. I was give no instructions on how to use it and I am not use to working with perl If anyone can give me some help I would really appreciate it. Here is the code.
