Then you don't have to worry about silly poo poo like user interactions you are a student, so this misconception is acceptable. i write firmware for a living and you very much need to worry about silly poo poo like user interactions (even in a device like a transducer where a human doesn't normally interact with it, you still need code for configuration and calibration and poo poo). in fact although the code that deals with user interactions is simple and boring I spend most of my time writing it, as marketing people will bikeshed endlessly about how a menu that is used once every thousand hours of device operation should be structured and oh by the way can you make the monochrome lcd turn red when an error condition is encountered?????? shouldnt be hard, it's Just Software(tm)

Then my code doesn't have to be very portable or maintainable for the most part (I still try to keep it clean and documented though.) Static memory allocation no mallocs everydayyyyyy.

I just really like messing with things on the register level.

Otto Skorzeny posted:oh also gently caress debouncing in software, throw a schmitt trigger on the button you shitheels yeah. like 10% of yosvape.c is loving debounce PERLCHAT: right now I am rewriting the installer script for packages for all of our handheld devices. We have to parse an INI-style config at the store server, and set flags "does this store have alerting turned on? does this store have mobile checkouts? is it a sam's, walmart, mexican bodega, asda?". Then we read the package config which has variable declarations like %imagepath%=/users/blah/blerp/ up top, and then statements like "signsays=sams;tag1" which is a basic if-then. We build up the tags of actions to execute, which are specified in XML. We build up a list of actions, copy the skeleton files for the package over to a sandbox, and then modify our sandbox files. Then they are pushed to the 'files are expected to be here' location on the server, and whenever the handhelds read those 'doot' files, they will know that the packages are updated and will download the new one. i have 0 idea how to do this in any other language, but a foggy idea of how to do it in perl. poo poo's crazy but imma make it happen

perl gets an undeservedly bad rap for large software projects. the limiting factor is the availability of decent perl programmers and people who are willing to write perl well, not anything to do with perl itself. it's sort of a self-fulfilling prophecy when shitheads who dont know gently caress from poo poo start complaining about how you can't write large programs in $LANGUAGE and people start listening to them.

not surprising that good perl programmers are in high demand, it is hardly a fashionable language anymore but there is a lot of code out there there is also a lot to look forward to in 10 years when php properly becomes the cobol of this century

Phobeste posted:how did you get into this sector? because this sort of level of stuff is what I want to do and I'm about to graduate and jeet christ I need a job 1. major in "computer and systems engineering", the bastard offspring of ee & cs. pay attention in class. 2. do a bazillion school projects and some lovely open source stuff and some hobby projects 3. while sending out resumes to places that won't give you an interview due to a less-than-stellar gpa, get cold called by a company that has had good luck hiring alums of your school 4. speak intelligently enough about concepts and their applications in the interview that you can convince them you're a good programmer and are more competent than a corpse wrt. electronics; for me this involved discussing the uses of the volatile qualifier, explaining how I2C buses work, discussing a time i fixed a bug by inspecting the generated assembly (in the context of vectorizing some matrix operations for one of the aforementioned projects), and discussing some stuff i did with CAN. obv ymmv. 5. await offer letter 6. (optional) don't be a complete doormat when negotiating the offer (i partially hosed this up) i assume you've done 1 and 2 3 was lucky for me but speaking to people at your school's career fair and not sounding like an idiot will also get you interviews (i got a couple with bad companies like cypress semiconductor this way). tailor your resume to each company obv. assuming 1 & 2 & that you have a pulse, #4 isn't too hard. it helps to research the company as well, and to take hints from the phone screen as to what you should brush up on for the live interview Blotto Skorzany fucked around with this message at 19:01 on Mar 6, 2013 |
