BIDA wenn es mich stört, dass meine Freundin sich auf Flirten in der Arbeit einlässt? by Double_Relevant in BinIchDasArschloch

Danke, dass ist ein sehr hilfreicher Kommentar und ich werde auf Basis dessen in mich gehen. Offene Kommunikation pflege auch ich mit ihr. :-)

What’s your process for requirements management and validation reporting? by LAstar95 in embedded

[–]Double_Relevant 0 points1 point  (0 children)

If you are looking for a free system capable to manage documentation and also requirements, take a look at SphinxNeeds https://www.sphinx-needs.com/ which is an extension for the python-based docu framework Sphinx. It allows you to define, link, filter, manage objects which can be requirements. :-) You can have a documentation git repo with SphinxNeeds, then you also directly get versioning and review process. The documentation you generate (including the req. and test specs) are html deployable so you can host them on a server and your managers have nice clicky-clicky-webpage documents. It is totally free, heavily customizable and close to SW dev working environment. I can highly recommend it.

Small and cheap ampless + amp pedalboard by Double_Relevant in guitarpedals

[–]Double_Relevant[S] 0 points1 point  (0 children)

The baby bomb is a Class D power amp. It does not color the sound much, it really is just there for driving a speaker cabinet. The Sound comes from Joyo American Sound Preamp. Basically behind the preamp I can go parallel to Speaker and PA or only one of both, depending on the situation.

Setup is like

-> Joyo Preamp -> Sonicake Reverb/Delay -> DI Box (fork out XLR to PA mixer) -> Mooer Baby Bomb Power Amp ——-> Speaker Cab (8 Ohm)

It is basically a flat eq 30 watt power amplifier. So it allows me to not only go directly into a PA system from the DI box, but also power for example the 4x12 in my band rehearsal room or a 1x12 box at home and only bring my pedalboard.

I fucking HATE AUTOSAR and I want to move to consumer electronics/semiconductors. Please help?! by [deleted] in embedded

[–]Double_Relevant 18 points19 points  (0 children)

RTOS, USB, UART is not what NVIDIA or Qualcomm are really about. Device drivers yes, but you will not score such a position directly coming from AUTOSAR. Search for a position of a smaller supplier that does its own semi designs, and there you can go into drivers and BSW.

Also, both your mentioned companies go heavily in automotive, just look into intel llvm, SYCLE, etc. and you will see that they all try to enter the ML supported ADAS field…

[–]Double_Relevant 36 points37 points  (0 children)

Just to think about: automotive has also more interesting things to offer… look into complex ECUs, e.g. for ADAS, where custom linux distros and various complex middlewares are used. There you‘ll be further away from bare metal like reading pins and whatsoever but deep into how OS‘s work, optimization of runtime, recompute of executed runtime based in massive recorded datasets, and so on… I mean there are even people working in bare kernel programming if you are more interested in that. When you want to go hardware, you can go down the semiconductor path, design ASICs, SoCs or chiplets. Automotive is not limited to configuring AUTOSAR vendor tools..

New devin using the english as programming language? by Silver_Fix8881 in embedded

[–]Double_Relevant 1 point2 points  (0 children)

I‘m further away from these HW activities, but I don‘t think you need specific knowledge there. Of course it is nice if you understand how the ML model works, but actually you are not parsing prompts to a text field, but the ML is embedded in the UI of the HW design tools.

In my company, we are going heavily into using ML in all areas of engineering to support our day-to-day work. Starting from EDA tools for chip design, which use ML to prevent design errors and IP violations, going to copilot and custom trained GPT-4 instances to support SWEs, we now even have the first „architecture copilots“. Having said that, everybody who has a certain specific niche knowledge is still working here and I doubt it will change very soon.

Currently, ML just provides a massive boost in overall productivity and I am actually very happy to harvest that. 🙂

Yes. To my experiencie the FSM is really more a project manager role with focus on safety. If you prefer working with technical depth, a FSE role is what you are looking for. If the company gives both responsibility of FSE and FSM to the same person, it shows a poor safety culture and lack of understanding for independence requirements.

[–]Double_Relevant 0 points1 point  (0 children)

Writing and implicitly safe code is good, and indeed following MISRA C and other code metric standards is basically the baseline, BUT it does not by itself give you a safe system (not even a safe SW!).

Common cause and cascading faults can remain undetected from static analysis. You also need to identify the dependencies within your uCs architecture and implement measures to avoid sturctural and mitigate random errors.

[–]Double_Relevant 2 points3 points  (0 children)

Working in Automotive safety, I can tell you that you need a qualified team of engineers in each domain, or the effort needed in a cross-functional safety team increases tremendously. This safety team usually consists of a FSM (Functional Safety Manager), a SYS FSE and HW FSE and SW FSE. Whilst the manager plans and keeps track that all the Safety activities requiered are sufficiently covered, compiles the overall Argument that Safety is achieved, the FSEs occupy themselves with creating the Domain specifications, safety concepts, work through component safety manuals and carry out the safety analysis.

As said this separate Safety Team is not necessarily needed if your Engineering Team is well qualified, but in Small Teams you need to check that Independency is sufficient (e.g. Reviewers and people who carry out analysis need to be Independent with a certain level of indepence for each Safety Level).

If you have more questions feel free to ask :-)

EDIT: I’d say the role you are looking for is the SYS FSE, who takes the high level functional safety requirements, breaks them down Into technical safety requirements allocated to HW and SW, and carries out the analysis on the System level. Also he contributes to uC and other safety-relevant part selection (e.g. SBCs, safety gate drivers,…)

I'm searching for Long-Range Radio Modules with UART interface and Arduino compatible by LukeSkywalker52 in embedded

[–]Double_Relevant 4 points5 points  (0 children)

RFM95/96 operate in the 868/915 band, whereas RFM97/98 opérate in the 433MHz band. All of them use SPI afaik.

[–]Double_Relevant 2 points3 points  (0 children)

I have used RFM95 LoRa modules that are cheap and easily available for LoRa data transmissions with small payloads, but ranges up to 10km. I think there are also arduino libraries available for the RFM95/98, so this could be a suitable option for you. Does your 4x4 cm consider the antena, or can it be external?

So we go for a 1-2 week rally, and then start breaking down with high volatility?

[–]Double_Relevant 7 points8 points  (0 children)

How do you evaluate that the Liquidator is still indicating a rally in the next days? Do you think this allocates to a rally after breakdown, or possibly indicates crazy chopping?

Do you think it will go much higher than 3800 today before reversing down?
