At the beginning of an interview...
HR girl: You know, that position you applied is already taken but I found some similar in our company.
Me: Uhm, ok?
HRG: What about this one? It's some programming... *pointing at some IT position regarding db maintenance* Do you want to try that?
Me: Sure, why not.
I was applying to student position at embedded firmware development at the time. I did some school project with MySQL but it was few years back and I happily forgot most about it.
Anyway, story continues.
IT manager: Hi, I heard you want to join our lines.
Me: That is what I heard as well.
Me: I came for completely different position actually.
IT: Uhm, ok. We have standardised test, let's see what you can do.
It was some basic stuff for db guys but I was totally lost. I was done after 3 minutes returning nearly blank paper.
We shaked hands, both agreed this is not well fit for me and I went away.
After this botched attempt HR girl remembered that there is another team looking for embedded developer students. I was accepted.
Corporates are marvelous.3
My mother used to code a good 30 years ago (embedded development for plane engines), but nowadays always fear doing something wrong on her computer/smartphone.
It's a bit depressing to see how someone who used to be a developer is now so fearful of computers.
On the plus side, she is very respective of my time, and will wait 2/3 weeks for me to come home to fix a simple thing, and generally don't bother me with things she can do herself, once I explain to her how to do it.
Last time was cleaning laptop fans. Seeing how you need to disassemble half of it to clean that, I can understand anyone not wanting to do it.8
I seriously do not understand the rants against Windows.
I love Windows 10 (got as free upgrade from MS), and have no issues with MacOS or Linux OS. I use them as well but do all serious work on Windows.
All my life, I have worked on business / commercial side and picked up Web development in last couple of years. I started using computers on DOS in 1992, and shifted to Windows 3.0 in 1995. There was no Mac or MacOS back then.
For serious work, I purchased a old Dell Precision M4700 workstation grade laptop with quad-core i7, at throwaway price, got 32GB RAM, 2.4TB (1x2 TB + 400gb) of SSD on super sale online, and installed it myself. It easily supports dual 4k monitors.
Git-bash on windows allows all the necessary linux command line on windows. Though not tried, Windows 10 allows embedded Ubunutu with linux terminal. Web development tools like - VSCode, git, github / bitbucket clients, NVM/Node, React / Redux / Webpack / Gatsby / Jest, REST clients, GraphQL client and server, Graph Server, Chrome PWA / Chrome Dev Tools, http/Websocket/WebRTC interception, Google Firebase SDKs, AWS sdks, cloud utilities, CI/CD tools work flawlessly. Windows even has its own package manager for applications.31
Where I work we develop drivers and command-line software for embedded systems. The contracts we have with our customers tend to be in the £100k-£500k range and are usually completed in 6 - 9 months; our team is made up of 20 developers. You would think that it would be worthwhile investing in the department. But no, instead we have to deal with >10 year old build servers on their last legs; limited numbers of development boards with wires soldered on so that we can keep up with new board revisions; no room for R&D into new products; and to top it all off, not one of the executives has a laptop on par with the placement students in the next department. It's like the company is trying to kill the department, we've seen our staffing dwindle with no new graduate (or higher) positions being made available in the last 3 years while we've lost at least 5 people to other places. I just don't get it!3
When searching for internship via school I found this small startup with this cute project of building a teaching tool for programming. There were back then 2 programmers: the founder and the co-founder.
Then like 1 week before the internship started, the co-founder had a burnout and had to get off the project, while the company was so low on budget the founder, aka my new b0ss, had to work separate jobs to keep the company alive. (quite metal tbh)
It's funny because I'm a junior developer, 100%. I've been coding as a hobby for around 8 years now but I've never worked in a big company before. (No exception to this workplace either)
First project I get: rewrite the compiler. The Python compiler.
"But wait, why not just embed a real compiler from the first case?"
-nanananana it's never simple, as you probably know from your own projects.
The new compiler, as compared to existing embedded compiler solutions out there, needed these prime features:
- Walk through the code (debugger style), but programmatically.
- Show custom exceptions (ex: "A colon is needed at the end of an if-statement" instead of "Syntax error line 3")
- Have a "Did-you-mean this variable?" error for usage of unassigned variables.
- Be able to be embedded in Unity's WebGL build target
All for the use case of being a friendly compiler.
The last dash in the list is actually the biggest bottleneck which excluded all existing open-source projects (i could find). Compliant with WebAssembly I can't use threads among other things, IL2CPP has lots of restrictions, Unity has some as well...
Oh and it should of course be built using test-driven development.
"Good luck!" - said the founder, first day of work as she then traveled to USA for **3 weeks**, leaving me solo with the to-be-made codebase and humongous list of requirements.
I just finished the 6th week of internship, boss has been at "HQ" for 3 weeks now, and I just hit the biggest milestone yet for this project.
Yes I've been succeeding! This project has gone so well, and I'm surprising myself how much code I've been pumping out during these weeks.
I'm up now at almost 40'000 lines of source and 30'000 lines of code. ‼
( Biggest project I've ever worked on previously was at 8'000 lines of code )
The milestone (that I finished today) was for loops! As been trying to showcase in the GIF.
It's such a giant project and I can honestly say I've done some good work here. Self-five. Over-performing is a thing.
The things that makes me shiver though is that most that use this application will never know the intricates of it's insides, and the brain work put into it.
The project is probably over-engineered. A lot. Having a home-made compiler gives us a lot of flexibility for our product as we're trying to make more of a "pedagogic IDE". But no matter that I reinvented the wheel for the 105Gth time, it's still the most fun I've had with a project to date.
Also btw if anyone wants to see source code, please give me good reasons as I'm actively trying to convince my boss to make the compiler open-source.
! exactly dev
I'd ditched Windows and spent a while exploring the Linux ecosystem for content creation. And I have to say, it was not a nice experience.
As much as I respect the Linux mantra of "free as in freedom" and "you need to roll up your sleeves and figure out stuff on your own", it just isn't good enough for non-dev work. Sorry guys, but I need software that gets out of my way and at least does what it's supposed to do. I can't stand a horrible UI or delays and random crashes, which is exactly what happens with most things under Linux.
To replace my Windows workflow I used the following:
1. Windows -> elementaryOS (because Debian/Ubuntu repositories seem to have the best software support, and elementaryOS is the least horrible looking thing that supports that) and then Arch, because, well, Arch.
2. Blender + Maya -> Blender + Maya on Linux.
3. Reaper + FL Studio -> Ardour + LMMS.
4. Photoshop -> GIMP + Krita + Inkscape.
5. ZBrush -> nothing :(
As you can see, my use cases are pretty much all over the spectrum.
Firstly, installing and configuring stuff. A pleasure on Windows, an absolute pain on Linux. Everything just worked on Windows, I had to wrestle with library versions and patches and unstable audio layers (Linux audio just sucks, except for JACK) on Linux.
Out of these, Blender and Maya were the best experience. But even then, both would suffer from random crashes that just didn't happen on Windows.
Ardour is actually really nice when it works. Its use of JACK for routing makes it really really flexible, but it just isn't stable enough to depend on. LMMS is utter crap. I'm sorry, but I just hate the UI. Can't stand it.
GIMP, Krita, and Inkscape can't beat Photoshop, even when you consider them together. Adobe software workflow is just so much better and more intuitive.
Blender 3D sculpting is not bad, but it's nowhere as good as ZBrush.
Also, if you're a C++ dev like me, nothing beats Visual Studio 2017. Nothing. That IDE just blows everything else out of the water. Even VSCode. And it's not slow at all, it handled a fairly large project (PBRTv3) just fine on my Windows development VM. Yes, a VM.
So...I ditched Linux and went back to Windows, but I keep Linux as a VM for when I actually want to mess with Blender or Ardour. Or some dev stuff which Windows sucks at (which is becoming less frequent because of WSL).
Out of all the above, the only one I'd consider ready for production use would be Blender. Developers of open source software, please learn from Blender. Kickass UI and user friendly operation is extremely important, you can't make a random window with GTK buttons and text boxes and arcane config files and expect people to use it for serious work.
Also, Windows beats Linux hands down as an everyday OS. It's always been rock solid, if you take care of it properly (and that goes for any OS). Updates hardly take any time because I run it on a SSD. As for all the advertising and marketing bullshit, you can block a large amount of stuff. And for what can't be blocked, well, I just have to live with it, because the alternative is compromising on my creative output, which is too much for me.
I still run Linux on my server, though. And on my embedded devices (Pi, BeagleBone, etc.). It absolutely rocks there.
I realize that Linux software is not going to improve unless we do something about it, so I'll be contributing fixes and code (the joys of being a C++ dev, yay). Still, I feel that the platform and software as a whole is just not mature enough.18
Sales guy calls up from overseas and complains website we got developed from another vendor is not working.
Being just the middle man who project managed the website development with the offshore vendor, I had no clue what was wrong as the site was working fine and "worksforme" was not going to be acceptable answer for the costumer demo.
Being an embedded drivers guy, had no idea to debug this, except one:
Me: Which browser are you using?
Me: try any browser other than I.E
Him: it works. Thanks
What kind of developer are you and what is your opinion on other development areas?
Me: Junior dev, oriented towards full stack and Android(with a sysadmin background):
-Low-level(kernel development, embedded, drivers, operating systems, reverse engineers)- Badass, I wish I could do that.
-Mobile apps- awesome but too high level sometimes.
-Full stack/Backend- awesome.
-Web Frontend- fuck HTML+CSS. JS is cool I guess.
-Enterprise applications(e.g SAP) Pajeet, my son.
-Malware development- Holy shit that is awesome.
-Video Game development- was my dream since childhood.
-Desktop apps- No opinion.7
Okay, first rant here.
Spend most of my morning searching for a js file that was supposed to build some graphs in a report page in this legacy system (still in active development) just to find it embedded inside a random .php file being included inside a wall of if-elses (that shit has around 100 lines) on the index.php (that somehow manages to route all the nonsense that's going on there).. was it really that difficult to make it a proper .js file? and actually import it on the page that is using it? c'mon...4
Why is pointers... bit shifting.. malloc.. anything that is regarding embedded development is so hard to grasp...18
Created a batch file to modify some system files on our embedded system.
Accidentally double clicked it in my development main machine :(
Man, fm fucking l2
Got an assignment in school to make an easy project in c for embedded real time processors with a free complexity level (it was really early in the course and many had never been programming before).
Since I've been working a few years in development I decided to create an own transmitter and receiver for an own protocol between processors (we had just spent a week to understand how to use existing protocols, but I made my own).
The protocol used only 1 line to communicate with half-duplex and we're self adjusting the syncing frequency during the transmission. I managed to transmit data up to 1 kbps after tweaking it a bit (the only holdback was the processors clock frequency).
Then I got the feedback from our teacher, which basically said:
"Your protocol looks like any other protocol out there. Have you considered using an UART?"
Like yeah, I see the car you built there looks like any other car out there, have you considered using a Volvo instead?1
So, I'm still not certain if it's actually a bug or merely my lack of experience, but I've been working on a 2D platformer game (using only C++ and SDL2) for roughly 2 years now (on and off; sometimes off for months) and I'm extremely embarrassed about this, but for the life of me, I cannot seem to get the player character's movement and collision physics working properly. It's driving me absolutely insane.
I've read articles and tutorials, referenced books, and posted about it in game development communities (e.g., gamedev.com, Discord servers, etc.), but even though the fundamental structure and explanations made sense, getting the code to work has been unsuccessful, albeit not completely so, but if I get one thing working, another thing breaks. It feels like I'm trying to repair a vase that fell off of a skyscraper and turned to dust on the street below.
I've always been a very tech savvy person with a fiery passion for programming, electronics and game/software/embedded/web development, but to be honest, having such a difficult time with things like this that — in theory, at least — seem like trivial bumps in the road have made me feel like I'm never going to be successful in this field. But regardless of the depressing thoughts of worthlessness, my passion doesn't let me stop trying. Who knows, maybe it'll have to remain just a hobby. 😕6
I am about to try TDD for embedded C. Does anyone around here tried that? What are your experiences with it? Thanks!13
There are several categories of software development that I know of: front-end, back-end, full-stack, game, mobile, embedded etc., but what is the term for developing libraries and/or CLI utilities in languages like C++, Python, Go etc. that are not related with any of the above? System development doesn't seem wrong but I was wondering what's the correct term for it in the industry because I need to mention it in my resume and on LinkedIn.
Also, if there's a lesser-known category that you work on then do tell us all about it 🙂5
I was working with my embedded systems friend a few days ago on a website, and since we work with electronics, it was something new.
I then went home and started learning web development.
Holy shit I love it
Here is a story about 5 years of my life.
My studies had little to do with web. I did embedded systems (architecture and software) but quickly realized that I couldn't see myself living my life in my homecoutry and that my degree would be worth little to no more than shit elsewhere in the world. That was on my 3rd year in uni.
I liked coding so I decided to pursue computer science, then web development. For that, your degree mattered little.
From then on, when I wasn't in class I was doing some coding.
This allowed me to get short (2 months) internships in Mobile and web development, 4 in total.
Doing so I had made it so that my professors would allow me to do my graduation project in web and mobile dev. That project having ended, I secured a long (1year and a half) internship in Mumbai India doing web for a big consulting company. Having finished that I headed to Belgium for my current job. All with having no to little financial resources except what I could come up with.
"I'm proud of all the efforts it took to make it" is what I think sometimes but what is it that I made? I realized my first objective which is to be on the international job market, but now that I genuinely love software I realize that I didn't really make anything I can be proud of working as a consultant. And having worked on many things but not a lot on practically anything, it's getting hard to do something else.
I'm hoping for devranters insight on how I should proceed.2
Now that I have your attention. My problem is with "IAR embedded workbench", not so much with windows but I'll get to that.
I've used that IDE for a few years.. 2 years ago. Since then I apparently forgot how to even create a project from scratch with adding all the necessary libraries and all that.
My initial deal with a client was to give them a solution using whatever tools I deem necessary. As I recently moved to linux and IAR is not available for that os.. and I also enjoyed working with CLion and PyCharm which Are available I decide to use CLion to write my C project.
A problem was that to compile code for microcontrollers I need tools unsupported by CLion.. oh well. I can do all the compilation and uploading of the code through terminal .. so I make a bash script that does it all. Super convenient. Development is going well and all.. until they ask me for the project.
I sent them the project so that they can see my progress. They can't do shit with what I gave them because they don't even have make on their machines let alone the compiler. All they have is IAR. But the guy that wants to see the code is not really a programmer.. he is a hardware specialist so I can't expect him to do anything more than use what he knows. He doesn't need or want to learn more right now.
So I go to windows and start porting my code to an IAR project and 2 days later I am still stuck with it. FUCK. Not only was the installation process horrible but the tools I wanted to install additionally did not work as promised either.
I know it took me about 2 days to setup all I needed on linux but I was enjoying it every step of the way. While this garbage is frustrating me so much. The fact that I used to do it before adds to the pain.
I am this close to telling them to just look at my code in notepad and I can setup a vm for them in which they can compile it if they really really need to.
If they just told me from the very start that they want me to work with IAR that would have been fine. I would have never seen the easier way and would have gladly figure it out then. Not now.1
I've been noticing that without any specialization development can become repetitive, as in, a bunch of fancy ways of doing the same CURD operations.
Something that just calls me is low level development, wether it is embedded development (microcontrollers and such) or Linux Kernel and device drivers. I've been polishing my C skills for a while now and started to look into kernel development and uff, is it overwhelming!
I just wanted to see if some of you guys are or had experience in system development and how you got there. Thx!3
Now that I've spent a few ineffectual hours too many trying to get it working, I'm starting to think VS Code wasn't built for the purposes I wanted to use it for. I still can't get breakpoints working anywhere close to reliably. And I'd say breakpoints are pretty important.
On a related note, if anyone here has used VS Code together with arm-none-eabi-gdb, I'd love some pointers. I've yet to find any traces on the web of people doing that…3
Much like traditional engineering I can see software engineering suddenly becoming very very regulated around the world. Different systems safety bodies will open up for things like embedded systems development where their is a risk of harm, mandatory security standards will be put in place etc.
Enjoy the cowboy days ladies/gents/others regulatory bodies are on their way!5
My ideal dev job, would be a job I can show compassion towards. A team I can be proud of and learn from. And a vibrant workspace with likeminded individuals who just want to improve themselves even if they feel their at their pinnacle.
My current office tries to make use of new technologies, we've embedded docker, vagrant, a few ci systems on an in need basis per team, and a lot of other tools.
My only real qualms are they feel indifferent towards new languages and eco systems ( Node.js, GoLang, etc ). Our web team is still using angular.js 1.x, bower, refuses to look into webpack or a new framework for our front end which is currently being bogged down by angulars dirty checking.
Our RESTful services are all using flask and Python, which become increasingly slow with our increase in services. I've pushed for the use of Node or GoLang with a GraphQL interface but I'm shot down consistently by our principle engineers who believe everything and anything must be written in Python.
I could go on, but tldr; I'm 21 and I have a ton of aspirations for web development. I'd like to believe I'm well rounded for my age, especially without any formal education. I'd love to be surrounded by individuals who want the same, to learn and architect the greatest platforms and services possible.1
I haven't chimed in on this spaces vs tabs war at all on this platform, mostly because I personally don't care and adapt to my work's/project's conventions, but I just have to put this out there now.
I am honestly so confused about the entire thing since seeing a lot of recent rants on the topic. I was originally conditioned to believe that the majority of devs in the world were FOR spaces over tabs. Thus, whenever I start a project, I default to spaces.
Contrary to that, it seems most devs here (or at least those who enjoy instigating some banter) actually prefer tabs. Now, I recently binged Silicon Valley and can't help but wonder if people around here are simply jumping on that band wagon for the sake of the joke.
Side note: I also thought Vim was more widely used over Emacs but Richard Hendricks asserts otherwise there too.
I know the main arguments for both sides - spaces yield code that looks the same in all editors while tabs produce smaller code. Anybody who argues that spaces are less efficient because you need to physically press the space bar 2/4/8/etc times is just retarded. If soft tabs weren't a thing, I don't think anybody would be on the side of spaces and for that reason I believe that episode in Silicon Valley was just trying to be overdramatized and push peoples' buttons.
I'm actually interested to find out what kind of environments breed these opposing mindsets so what do you guys think?2
My company just released its website today. Previously, it just used its parent company's site.
Now, the problem is that it sucks big time. Awful design, pixelated stock photos, bad navigation, and broken grammar.
In the company's defence, it's not a web shop. It employs zero web devs. The site was built by an external company.
But if you are like me, you visit company websites before you apply for a job, and in this case, it would bed a big red flag.
Or maybe the hard-core embedded devs they are looking to employ wouldn't notice? Maybe they are all stuck in the year 2000 as well? I used to be a web developer so maybe my criteria are broken?3
Hello, I’m considering building a web framework.
My ideal features would be:
Customizable authentication system(considering using a jwt lib)
Embedded DB(bolt db)
ORM( writing my own)
REST api to DB (via code generator)
Code generator(generation of models and views via cli)
GUI to db(some admin dashboard)
CORS(web service right?)
Ease of development
Fast prototyping of small-medium web services.
My question is, do i have to many things on my platter? Should i narrow it down into less featured framework? What feature should I focus on? How should i benchmark it? Should i write tests for absolutely everything or just for exported methods? What should i take into consideration when developing ORM API, Auth API...
The language is Go
Thank you for your input11
Definitely landing the first real gig.
I've been writing software since I was 12 (full disclosure: early code consisted of C=64 BASIC). I learned C in high school. Contributed to a MUD in my 20's. But I never got a CS degree and didn't really understand how hiring works, so I limped along doing technical support for years. Years turned into decades.
About 2 years ago, I became an embedded support person inside a development team. I got to show off my skills, and the year effectively became a live interview. Last October I finally got the title.
On the positive side, by taking the long way around I missed out on some of the insanity of the software world in the 90s/00s.2
I started early making money with programming, but currently I'm still studying to get into embedded development. My dad is very jealous of me being a programmer. He's biting his ass for not learning programming himself in the early years of c64 and so. He was just fascinated by using a PC, his friends wrote little games. He mainly believes, that he would earn a lot more. (Haha, …)
My mom tho, she doesn't ask about my subject or what I do or will do in future. I think, she doesn't really care but knows I'm doing computer stuff.
When I created my first app on RaspberryPi. It was an app that watches window sensors and shows the information about windows status (close or open) and shows the information on web application. Тhis was my first time when I faced with embedded development with Python.
So when I started at my current company, I was the second developer in the company. My job is to handle the embedded development side of our product. The existing code base? Made in fucking China. All of the comments were in Chinese too. They had implemented Huffman compression incorrectly and AES CBC encryption incorrectly as well. It was seriously some of the worst code I've ever seen. I remember one gem I found:
Int header = *(*int) "MGIK";
I've heard all kinds of arguments for about how whiteboard coding interviews should be obsolete, and that they usually doesn't reflect how good you are as a developer. But I've been polishing my skills with data structures and algorithms for a few weeks (learning this stuff for the second time since years ago in college) and I get this feeling that I'm becoming a much better programmer by practicing these things. And having access to all these things in the "working memory" of my brain has made me now think of solutions I couldn't before. But then - it may be that right now I'm working on embedded systems so this efficiency matters much more, earlier while doing full stack web development I didn't care about these much except while playing with strings maybe. So it might be dependent on your niche. What do you guys think?3
