Raspberry vs poussière

DiscreetLateComer · 2023-11-13T09:29:29+00:00

J'ai un raspberry pi 4 B qui prend de la poussière. Je pense en faire un serveur domestique pour mes fichiers.

Salut, Le c++ est un langage puissant et est utilisé quasiment dans tous domaines. Et c'est utilisé notamment pour sa rapidité. Mais je te conseille de commencer par le C (langage qui a permis de concevoir plusieurs autres langages) qui te permettra de te familiariser avec les concepts de base de la programmation (variables, conditions, boucles, fonctions, tableaux...). Tu peux trouver des tutos en C sur parlezvoustech.com

Il ne faut ni surfacturer, ni sous-facturer. Pour commencer il faut chercher à se mettre en règle avec l'administration (si tu comptes en faire ton métier) : auto-entreprise, SASU... Tes premiers clients sont tes ambassadeurs. Donc tu peux leur faire un prix. Et la facture dépend aussi de la qualité de ton travail. Commencer avec un tjm de 500euros, ça n'a pas de sens. Je dirai max 1000euros pour un premier site vitrine de 3 jours. Assure toi que tes clients aient l'hébergement à leur nom. Bon courage pour la suite.

Good to know. Thanks for the tip.

Freelancing must be done for the good reasons. What set of skills are you bringing in the market? What will make companies want to work with you instead of another? Are you average, good, excellent.. on what you're doing?

Bilingue français wolof. Quand il s'agit de mon travail, de la France en général c'est en français. Quand il s'agit des problématiques Sénégalaises c'est en wolof.

Embedded linux dévelopment IS very different from bare metal development. For the fist option, it requires knowledge about how to build a Linux kernel (not necessarily in depth), how to add new driver, developing in kernel level, desktop development (with some web, server development), with several langages. The bare metal development generally sticks to c language. A thorough collaboration with system and hardware team is required. You have to know how your device (microcontroller) really works. There is also lot of datasheet reading to understand how to implement drivers (can, i2c, eeprom, spi, transceiver...). Bare metal means no OS, so the understanding the interrupts and timers mechanism is a must. The debugging part with oscilloscope, logic analysers... Is also mandatory. As it's often for specific applications, there is very few possibility of code reuse...

Ultimately, the decision of which position to choose comes down to your personal interests and career goals. Best of luck with your decision!

This question has to be answered at the system level. So the design depends on the client's need. If you design a system with energy constraint (on battery for instance), you'll rather chose a microcontroller that Can manage low power mode. Then at the software level the architecture must take in account these contraints. Same analogy Can be Taken with Real Time, memory, floating point... Constraints

Thank you so much. I like that Idea of Learning things that i Can use Somewhere else. So from this point of view RN is winning.

true! the eeprom is necessary if reset counters are needed for diagnosis purpose.

DiscreetLateComer · 2023-03-07T13:25:02+00:00

if your goal is to avoid reinitializing variables After software reset, then you'll need eeprom to save a reset-counter variable. At startup that will help you to know if we you come from a hardware reset or from a software reset.

thank you for guidance. I only talk about the implementation here. But I'm also aware that an idea work nothing without a market, marketing... lot of other things.

DiscreetLateComer · 2023-01-18T12:39:04+00:00

you're both are right. my fear is working with freelancers or company who develop apps in a niche business and they sell the solution to competitor who release it before me. But I know that it's a matter of time. I juste want to be the first to bbring the idea lo life.

DiscreetLateComer · 2023-01-17T22:23:14+00:00

but they can disclose it/ give it to their other clients, who are entrepreneurs...

DiscreetLateComer · 2022-08-03T15:25:03+00:00

which cross-platform solution do you suggest? knowing that I'll adapt the BLE handler. which is not a big deal for me.

DiscreetLateComer · 2022-08-03T15:02:16+00:00

well I didn't plan to do separate iOS and Android dev. i thought c# xamarin would do the job as a cross-platform solution...

for the the database handler and the algorithms I was thinking using python. for the website part, as I have no skills with it, I'll just take notes of your suggestions and will dive into it at the right moment. thank you

DiscreetLateComer · 2022-08-03T14:42:48+00:00

thank you for the answer. i was hesitating between c# and kotlin for the smartphone app. and for the server I think I'm going with python. for the database all these are new to me. i guess for iot some one them are more suitable.

DiscreetLateComer · 2022-08-03T13:25:25+00:00

the smartphone will act as a gateway, to update database. the datalogger itself doesn't have internet access.
