A Decrementing loop that compares against a zero is faster (even though insignificant on current hardwares)
than an Incrementing loop that compares against a constant/variable.
for( i = num; i != 0; i -- )
is faster than
for( i = 0; i != num; i ++ )
The difference shows up significantly on resource constrained hardwares such as 8-bit microcontrollers.

Worked all day and got my embedded systems project working the first time! Bluetooth as well! 😁
It's a Fitbit clone that keeps track of steps that I did from scratch and writing the companion app from scratch as well in flutter/dart. Ask any questions if you're curious!35
That's it. I fucking quit.
Over a month of unpaid work, developing your stupid course, only to get a high-quality outline rejected because "it's not what we wanted" again.
First outline, fuckers ask to do something with a Raspberry Pi and Yocto. Fine, but no Yocto as I don't know anything about it and the coworker doesn't even have a Raspberry Pi to flash the images on. Micromanagement guy (god I hate that word) agrees, fine no Yocto then. So no Yocto it is.
2 weeks later... Course outline is finished. Review stage.. rejected. Needs moar Yocto.
Fine... I'll include Yocto. Coworker was put off the course, I'm exclusively on it now. Time to do it well and get my feet wet with Yocto.
2 weeks later... Course outline is finished and looks pretty good. Review stage.. rejected. Needs less Raspberry Pi. Do it without the Raspberry Pi.
An embedded systems course whose core component is that fucking Raspberry Pi. Omit it they said. WHAT?!!
"Oh yeah but there's this other course that's selling like hot pockets, we can just redo that in videos. Make it more like that course."
You.. you can't be for real, can you? If students want to take that course... What makes you think that they wouldn't just pick.. *that damn course* then?
"But hey" micromanager said, "don't loose hope and confidence, I'm here🤪"
🤪. That describes your level of competence pretty well, you stinking piece of apeshit.
Go back to your micromanaging, at least you don't completely fucking suck at that.
2 times rejected because YOU fucking company's board can't describe your desires in a course properly. You know what, I think I'm starting to understand why web devs keep on complaining about indecisive clients now. Because you know company's board, you seem a lot like those clients from hell. Eat shit.
"We see you have JS experience, how about a job as a Senior C Embedded systems engineer, we can only pay 30$ an hour "2
Someday in an embedded course:
Lecturer: "You'll want the following drivers and SDK for this lecrure. With some tweaks it'll also work on Windows."
Guy with shiny Mac infront: "What about Mac?"
Lecturer: "WTF? You don't use Mac for embedded systems." o.O
Me: lol 😁5
So I got a call from a recruiter this morning, about a job for a C++ developer what experience developing for embedded systems.
He sent my resume off to the company and they actually want an in person interview the same day.
I'm going to this interview in 2 hours, I'm really nervous, I haven't had an interview in years...
Wish me luck!12
Today we presented our project in Embedded Systems. We made our so called "Blinkdiagnosegerät" (blink diagnosis device) which is used to get error codes from older verhicles which use the check enginge light to output the error. (for reference: http://up.picr.de/7461761jwd.jpg ) This was common for vehicles without OBD.
We made our own PCB, made a small database for 2 vehicles and used a Suzuki Samurai instrument cluster for the presentation (hooked up to an Arduino UNO and a relay for emulating some Error Codes)
Got an 1.0 (A) for the project. Feel proud for the first project done in C++ and making our own PCB. So no rant, just a good day after all the stress in the last weeks doing all assignements and presentations.
Next week we hopefully finish our inverse pendulum in Simulink and then the exams are close. :D20
To my fellow 🐍 charmers:
You should see in C to understand C, else you'll never see what's in C. It's a big sea, you better start C. 😍16
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
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.5
Next month I'm starting my master studies in embedded systems. Currently I have not any knowledge in this topic (made my bachelor in an other part of IT). Any tips or tricks?
Currently I'm starting learning C++ 😅13
First year: intro to programming, basic data structures and algos, parallel programming, databases and a project to finish it. Homework should be kept track of via some version control. Should also be some calculus and linear algebra.
Introduce more complex subjects such as programming paradigms, compilers and language theory, low level programming + logic design + basic processor design, logic for system verification, statistics and graph theory. Should also be a project with a company.
Advanced algos, datastructures and algorithm analysis. Intro to Computer and data security. Optional courses in graphics programming, machine learning, compilers and automata, embedded systems etc. ends with a big project that goes in depth into a CS subject, not a regular software project in java basically.4
Do you guys think it’s time “Hackers” gets its 2020 remake? I know it was cheesy for its time (1995) but 8 year old me was INTO that music video montage direction and that movie inspired was what inspired me to get into tinkering with electronics/embedded systems.
Rewatching it tonight and the casting is so on point, too.5
Many people here rant about the dependency hell (rightly so). I'm doing systems programming for quite some time now and it changed my view on what I consider a dependency.
When you build an application you usually have a system you target and some libraries you use that you consider dependencies.
So the system is basically also a dependency (which is abstracted away in the best case by a framework).
What many people forget are standard libraries and runtimes. Things like strlen, memcpy and so on are not available on many smaller systems but you can provide implementations of them easily. Things like malloc are much harder to provide. On some system there is no heap where you could dynamically allocate from so you have to add some static memory to your application and mimic malloc allocating chunks from this static memory. Sometimes you have a heap but you need to acquire the rights to use it first. malloc doesn't provide an interface for this. It just takes it. So you have to acquire the rights and bring them magically to malloc without the actual application code noticing. So even using only the C standard library or the POSIX API can be a hard to satisfy dependency on some systems. Things like the C++ standard library or the Go runtime are often completely unavailable or only rudimentary.
For those of you aiming to write highly portable embedded applications please keep in mind:
- anything except the bare language features is a dependency
- require small and highly abstracted interfaces, e.g. instead of malloc require a pointer and a size to be given to you application instead of your application taking it
- document your ABI well because that's what many people are porting against (and it makes it easier to interface with other languages)2
Currently i am working as a student at a teaching chair for embedded systems, so my boss is the professor there and the subject of this weeks story 😄
He is very passionate about his field and keeps close contact to the students and their representatives.
He invests a lot of resources into getting students to learn and make projects and pays us to supervise a hands on course for students to build IoT projects.
As employees we get to work on interesting projects and he listens to us and our concerns if we feel a project is having certain problems.1
bool firstRant = true;
I've been lurking for a few weeks. I just got my first ever full time position as an embedded systems programmer for a small-ish company. For context, my background is with application devlopment, not embedded systems, so I am surprised I even got the position.
Regardless, I am kind of pissed off because the pay is only like $13.50 an hour (I live in California, the minimum wage here is $11.00 an hour.) I think it is bullshit but this job is my best option. Im still fucking salty and I know people woth internships that pay $20 an hour.8
So I'm taking embedded systems subject in my masters course. They have mixed this subject's content with electrical engineering and I'm a computer science graduate. Everything was perfect until I reached to GPIO board.
Wtf is this shit?
Why it has so many holes and what are they for?
What I'm supposed to do with it?
What is ground? Transistor?
Why I'm connecting to two pins only instead of the 4 pins of a button?
Thanks to pi4j i think i will pass the subject!2
In highschool, I was looking around for schools and universities at which I would start my student career. I went to a grad school one day, to see what it was like to be a student there. The first class I visited was programming for embedded systems. We got the assignment to write Java code to control a boom barrier. The teacher had written the template. And I kid you not, the template had a method of around 20 lines of code - without comments - with the purpose of carrying out a logical OR operation. An operation that literally can be done using an operator in Java: |
Why oh why do they let these people teach, with the result that the students will get used to these bad practises...5
Just read a job posting for a junior .Net software dev. 2 years experience in C#, Visual Studio, .Net. Usual suspects right, though two years experience for a junior seems off. But they also want embedded systems experience. wat?4
Any embedded systems software engineers out there with practical experience in writing/designing safety critical applications? (think DO-178B/C) I've got a few years embedded experience under my belt between internships, my projects, and now my relatively new job at a major aviation company, but I feel like I'm behind on this topic of safety and code that can't fail. It's simply not taught and I really want to learn more. Partially it is out of personal pride because I want to make a great product, but more importantly, what I work on is protecting a human life. I really really really want to feel confident in what I build. Is there anyone out there who's got some years under their belt that can point me to some good references? Or maybe some helpful tips? Much appreciated. If it helps, all my work is in C.10
Developer vs non developer interview:
How well do you know excel ?
How would you write spreadsheet app, what if it was cross platforms mobile application but also desktop app ?
Do you know how to use windows?
Do you know kubernetes, distributed systems, lambdas, cloud services and how to deploy to server farm ?
You know how to use printer / fax and coffee machine ?
Do you have experience in writing code for embedded devices ?
Do you know powerpoint ?
React native and native apps maybe ?5
It was in old days when I was working in java and windows systems.
Java and different log4j versions across dependencies caused system not working only on production server.
Turned out some of libraries got log4j embedded and conflicted with other log4j.
It worked in all computers except production one.
Actually that was my main reason to switch my career to python after that dependency hell.
Another one was windows server 2008 tcp connection limit set to 200 or something.
We needed to change registry to get our servers working. After this case we finally managed to convince people to switch to linux.
Anyway any non standard error when you got multiple layers communicate with each other is hard, practice make it easier to solve those problems as your success moment comes faster.4
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
Anyone here worked a whole lot with low level programming?
I have always worked with high level languages like Python and C++, but I’ve also had an interest in working with embedded systems, real close to the metal.
Any directions on where I should go to start learning low level programming? Sites, languages, etc?
Appreciated devRant fam!😊14
Today is just me and my friend, two embedded systems geeks making a website.
It’s going awful but it’s fun as hell😂4
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.1
So today (as of 5 min ago) marks a great day for my personal projects! I just got my embedded systems Flash memory driver debugging on my PC in Visual Studio, talking directly to the REAL flash chip, WITHOUT being tied to a embedded target! It's glorious. I can finally debug and write tons of tests without having to worry about the constraints of my embedded system. Ahhh. All the pieces I've needed to build this have slowly come together over weekends, and it feels so good to have this tool in my arsenal now! Great day indeed.
You may soon have a new operating system from Google to run on your Raspberry Pi. Details are still extremely sparse, the only description on the GitHub page is “Pink + Purple == Fuchsia (a new Operating System)”. But, here’s what we do know:
The new OS, called Fuchsia, will be based on Magenta, which is in turn built on LittleKernel. That means that, surprisingly, Google will not be using a Linux kernel for the new OS but something more like an embedded RTOS. Although Google is targeting embedded systems, the possibility of being able to run it on a desktop has been mentioned, so it may not be too minimalistic.
Google’s Travis Geiselbrecht has named the Raspberry Pi 3 specifically as one system it will run on, and said that it’ll be available soon. But, it seems Google is aiming to make it run on a variety of ARM devices (both 32 bit and 64 bit), as well as 64 bit PCs. This is a direct effort to compete against other commercial embedded operating systems that are currently available, and especially on IoT devices.1
Any electrical engineers/tech hackers here?
I am planning to do raspberry & arduino project, basically it’s TV ambilight, but with camera recording the tv screen. Now I have a lot of stuff figured out already, will use wide angle camera connected to raspberry (so I can use it very close to the tv), it’s gonna record screen at lowest resolution which should be enough to analyze colors through opencv and has quite high bitrate. Behind the tv will have led strips around with arduino hooked, which has wifi shield connected.
Now key here is to capture image, analyze it, build array of colors and send it to the arduino to change the colors of led and everything 60 times per second (fps to match tv).
Amount of data is 0.3kb with 100 24bit leds, which is incredibly low.
I am not entirely sure how wifi works internally, but will it be handle to transfer data 60x/s, where not the size is the problem but actually the amount of transfers done? I should also take into account all other appliances using the wifi (pc, philips hue, phone...).
Or will it be more reliable to hook led’s directly to raspberry through wire (which’s also a cheaper option)?7
I'm new around here and I'm part of the niche of embedded software developer.
Is there any fellow MCU programmer around here?
Have a great night everyone!7
Is there any hope of getting a job that isn't web related? Every embedded job I've seen requires years of experience. I just want to write C dammit.2
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
At work we develop for embedded systems. Using the heap can raise unknown effects sometimes. So we always try to avoid using it. To show our attitude regarding the heap we want to make T-Shirts like the No Ma'am shirts from Married... with Children but with No Heap instead of No Ma'am. Now we need a meaning of the acronym. Our currently idea is:
We do not find a good word for the E, we also aren't native speaker, thus we are not sure which synonym for word like based can be used in such context. So i want to ask if someone has a good idea or even a better idea for the whole acronym :)3
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
First and foremost, students should be carefully taught the logic and mentality behind programming. Most of the time I see that the introductory programming courses waste so much energy in teaching the language itself. So students kinda just get fucked cause many people end up ending the course without having actually gained the "programming perspective".
Stop teaching pointers and lambdas and even leave the object oriented stiff till later. If a student doesn't know why we use a For loop then how can they learn anything else.
I believe once that thing in your brain clicks about programming, everything goes smooth from there... kinda :P
Second of all, and this pertains mainly to the engineering and science disciplines.
We need a fundamental and strong mathematical foundation. And no I don't mean taking fucking double integrals. Teach us Linear Algebra, Graph theory, the properties of matrices, and Probability theory.
One of the things I suffered from most and regret in university is having a weak foundation in math and having to spend more time catching myself up to speed.
It's so annoying reading a paper on a new algorithm or method and feeling like an idiot because I can't understand what magic these people did.
Ok this is more deeper, maybe a 2nd year course.
But this is something we take for granted.
Computers don't magically add and subtract and multiply.
They fuck up.
And it'll bite you in the ass if you're not even aware that the computer we all love so much isn't as perfect as we think
Some hardware knowledge.
Probably a basic embedded systems course with arduinos
just so you can get a feel for how our beautiful software actually makes those electrons go weeeeeeeee
just give me the internet and some projects
Ill learn everything else
Projects are the best motivation
I hate this purely theoretical approach
where we memorize or read code and write these stupid exams
Test what we are capable off
make us do projects that take sleepless nights and litres of coffee
And judge our methods, documentation, team work, and output
Team work skills and tools (VCS, communicating, project management, etc.)
Documentation and Reporting
maybe even with LaTeX :D
Yeah that's the gist of whats on my mind at the moment regarding an ideal computer science education
At least the foundations
The rest I leave it to the next dude.
I gotta say I really love the beauty of being able to merge math, code, and hardware all in a well tuned symphony to make something awesome. Building an LQR controller for a custom quadrotor flight controller and it is just so much fun!
I’ve been on devRant for a very short period of time and I’ve seen too many posts about PHP fucking people in the ass.
Is it really that bad?(I’m an embedded systems geek so don’t ask me why I don’t know anything about PHP)18
Not much tops the orgasm from powering thru 500+ lines of code in the zone... in vim...no debugger.. and without compiling just visually seeing in your mind the assembly be generated... and code being stepped thru.. and then compile and test and everything works as expected.. not sure anything tops that feeling ... definitely have to be in the zone.. one distraction and boom gotta compile to make sure nothing broke3
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
A lecturer for an Embedded Systems module who gave out drivers for an LCD display with no documentation at all, and about 4 functions for writing to the display and 3 initialisation functions, spent ages trying to actually decide what each function did by which memory addresses it was changing and how (made even better by the fact a good bit of the functions were written in Assembly since it was Embedded C)🙃
I’ve 2 great job opportunities and would like to get some opinions from you guys..
The first position is in my home country, I’ve passed the first interviews and (highly advanced) coding test.
I’d have the possibility to contribute to something big that really matters nowadays.
I would learn about lots of stuff that really interests me (security, embedded systems...)
The second position is in another country, I’ve passed the first interview and just received the coding test.
There I could work on a cool project and I’d definitely learn a lot there, too. But more important is that I love the county, there I really feel like “home”, I love the people and culture.
In case both of them want me, it would be really Hard to make my decision..
What would you do in my situation?
- dream job in a country I don’t necessarily like, neither dislike
- cool job in a country I totally wanna settle down sooner or later (but currently wouldn’t have problems getting the permissions and stuff..)?
Thanks in advance:)1
Programming embedded systems from scratch. All hardware, memory, timers, peripherals, etc, must be set up correctly at startup, and if you set even one single bit incorrect in any of the sometimes hundreds of 32- or 64-bit configuration registers, you are screwed. There is often no terminal that prints error messages to help you, but if you are lucky you have an (often very expensive) hardware in-circuit debugger to step through the start up code.2
So I ran into a perplexing "issue" today at work and I'm hoping some of you here have had experience with this. I got a story-time from my coworker about the early days of my company's product that I work on and heard about why I was running into so much code that appeared to be written hastily (cause it was). Turns out during the hardware bring-up phase, they were moving so fast they had to turn on all sorts of low level drivers and get them working in the system within a matter of days, just to keep up with the hardware team. Now keep in mind, these aren't "trivial" peripherals like a UART. Apparently the Ethernet driver had a grand total of a week to go from nothing to something communicating. Now, I'm a completely self-taught embedded systems focused software engineer and got to where I am simply cause I freaking love embedded systems. It's the best. BUT, the path I took involved focusing on quality over quantity, simply because I learned very quickly that if I did not take the time to think about what I was doing, I would screw myself over. My entire motto in life is something to the effect of "If I'm going to do it, I'm going to do it to the best of my abilities." As such, I tend to be one of the more forward thinking engineers on my team despite relative to my very small amount of professional experience (essentially I screwed myself over on my projects waaaay too often in the past years and learned from it). But what I learned today slightly terrifies me and took me aback. I know full well that there is going to come a point in my career where I do not have the time to produce quality code and really think about what I am designing....and yet it STILL has to work. I'm even in the aerospace field where safety is critical! I had not even considered that to be a possibility. Ideally I would like to prepare now so that I can be effective when that time does come...Have any of you been on the other side of this? What was it like? How can I grow now to be better prepared and provide value to my company when those situations come about? I know this is going to be extremely uncomfortable for me, but c'est la vie.
TLDR: I'm personally driven to produce quality code, but heard a horror story today about having to produce tons of safety-critical code in a short time without time for design. Ensue existential crisis. Help! Suggestions for growth?!
Edit: Just so I'm clear, the code base is good. We do extensive testing (for lots of reasons), but it just wasn't up to my "personal standards".2
Hey remote workers.
What would be your advice for someone with experience that's interested in exploring remote work.
I'd like to target this question to remote workers that live outside USA/EU/UK. Say South America, South Asia.
A little introduction.
I'm a full stack engineer, did one project in embedded systems with QT/C++/RPI can do backend in Python, Node, Java, C#. I have some experience with React Native (just 2 apps)
I currently I do full stack with Node, React, postgres and caching with couchdb.
I gather requirements, write the projects, proposals and then I do the implementation. (Really full stack, I kinda like it though, when I'm bored with code I pick up an issue and contact the client to socialize/get answers. I found out that nondevs like to feel they talk to a human not a robot)
I'm making about 600usd/month (dev in a poor country) working 30hrs /week. I'd like to ramp up my income, working remote part time to fill up about 50hr week.
What can I expect?
Where do I start?
Are there part time opportunities for working remote?
What kind of roles are in demand?9
So this embedded product is already a year late as cutting a task from the schedule didn't make the problems it would have addressed go away.
Now there's a performance issue (turns out to be how the customer had configured something) after we've been stumped for over a month and not got any closer, theres a meeting with the design authority, project manager, systems engineers etc, we say we can't tell where the issue is exactly, can't easily tell what Linux is doing all the time etc etc, so this product does a lot of IP processing, the project manager asks - do we even need an OS?
Are you having a laugh?! We barely took him serious before this meeting, we still don't now and it was three years ago! I mean, who wants to write their own OS and associated infrastructure themselves? 1 year late already, think you can add another 20 man years onto that!
So I was working on Nex Robotics's Firebird V,
Was doing some graph traversal thing...
And was breaking my head for 28hrs... I was passing the bot an structure of direction and no. Of times it had to take that direction...
something like for(int i=0; i<dir.times;i++)
And after 29 hrs I realized it also had negative values...
that effing abs() was missing 😫4
TLDR, need suggestions for a small team, ALM, or at least Requirements, Issue and test case tracking.
Okay my team needs some advice.
Soo the powers at be a year ago or so decided to move our requirement tracking process, test case and issue tracking from word, excel and Visio. To an ALM.. they choice Siemens Polarion for whatever reason assuming because of team center some divisions use it..
Ohhh and by the way we’ve been all engineering shit perfectly fine with the process we had with word, excel and Visio.. it wasn’t any extra work, because we needed to make those documents regardless, and it’s far easier to write the shit in the raw format than fuck around with the Mouse and all the config fields on some web app.
ANYWAY before anyone asks or suggests a process to match the tool, here’s some back ground info. We are a team of about 10-15. Split between mech, elec, and software with more on mech or elec side.
But regardless, for each project there is only 1 engineer of each concentration working on the project. So one mech, one elec and one software per project/product. Which doesn’t seem like a lot but it works out perfectly actually. (Although that might be a surprise for the most of you)..
ANYWAY... it’s kinda self managed, we have a manger that that directs the project and what features when, during development and pre release.
The issue is we hired a guy for requirements/ Polarion secretary (DevOps) claims to be the expert.. Polarion is taking too long too slow and too much config....
We want to switch, but don’t know what to. We don’t wanna create more work for us. We do peer reviews across the entire team. I think we are Sudo agile /scrum but not structured.
I like jira but it’s not great for true requirements... we get PDFs from oems and converting to word for any ALM sucks.. we use helix QAC for Misra compliance so part of me wants to use helix ALM... Polarion does not support us unless we pay thousands for “support package” I just don’t see the value added. Especially when our “DevOps” secretary is sub par.. plus I don’t believe in DevOps.. no value added for someone who can’t engineer only sudo direct. Hell we almost wanna use our interns for requirements tracking/ record keeping. We as the engineers know what todo and have been doing shit the old way for decades without issues...
Need suggestions for small team per project.. 1softwar 1elec 1mech... but large team over all across many projects.
Sorry for the long rant.. at the bar .. kinda drunk ranting tbh but do need opinions...
Just started my new college education (going for embedded systems engineering) and we found out we don't have any holidays except for christmas.
No biggie, can live with that.
However, we just got a project which we need to pass to continue to the second year and of course it's a fucking group project.
Guess what, one of the asshats had a holiday planned for a while, so he'll be out somewhere in Africa while the rest build stuff for a week. 1 week on a 3 week project... Amazing.
Oh... I dont know what to pick...
So i will pick 3 projects from my 3 stages of my dev "carrier"
1.Right after i discovered programing and learned how ,if, while and similar structures worked. The launguage was object pascal with delphi 2007
That was a "safe" with a stupidly complicated lock (text inputs, sliders, ect) it opened a secret folder in the end.
2. It was a embedded code for a Atmega8 AVR, Atmel studio, pure C but without memory managment (i didnt even know that it even existed)
It was a Pip boy knockoff, 16x2 display and a small keyboard connected to the arduino like board that i made on a proto board.
It wasnt that much of a pipboy, it was more of a showoff of atmega8 internal systems, (ADC, timers, interrupts and such)
3.DataLab, after helping my friend with his master thesis, (we meet on discord long story, i was in high school) i decided that mathlab is shit and i created a visual scripting enviroment, launguage C# .net 4 (in the latest version)
I remade the whole program from scrach 1 time, significantly improving everything (code reuse, better algorithms, data processing, code redability and edge cases) I have learned good practises from everywhere. I learned how to use git.
DataLab project looks just like LabViev (i didnt notice that it even existed...), it is frozen now because of my mental status but im planning on using it on my CV when i will be looking for jobs on holidays. There are many things that i can improve in that program but ... first i have to fix myself.
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
Alright, what the fuck is embedded systems and how does it differ from regular programming? I am not getting jobs because I know the languages requested, but I don't know embedded systems. How do I learn it? Get a Raspberry pi?12
Job interviews finished! I just kept one at Rouen (embedded systems) , and now I'm waiting the answer for Nice (Cry Engine).
Gosh I want to live in Nice and be a game developer, that looks really fun. I mean I enjoyed the test x)
Let me hope a bit guys :p
We have a C++ for embedded systems training at work this week.
References are a good thing but after looking for the reason why one object has no reference to the other for half of an hour just to realise that my member wasn't a reference so that i got an copy gave me the urge to use pointers instead. But unfortunately we'd to use a reference in this simple exercise which cost me a lot of time because that damn reference.2
Infineon infineon infineon...
Your aurix tricore is amazing for all safet systems... On paper.
Your support is abysmal. Tried forums, support line to verify a demo that only seems to work sometimes.
I just wanted to get ethernet communication using the demo. But hey one week gone and no success....
And the code seems to behave differently for each run :| the debugger works only on global variables and no printf statements. But hey just make a lot of globals right? So little footprint available so not possible :-\
Hoped that some forum could confirm the demo so I knew I was just making a fuck up, but cannot get that verified...
Embedded programming not for me... :/
Any c++ embedded system programmers here.what kind of work do you do ,what are your daily tasks etc.and what boards do you use
Through out the week I break my head on embedded systems...
And fuck my brains out playing DotA2 on sea server with pinoys on weekends...
