Context: I'm studying sequences and series as part of my calculus course. What I'm doing differently is during viewing the material for first time is advance on small parts, let's say one or two theorems and examples. Then I try to elaborate my notes without seeing the material and after I review what do I miss and what I did not get. Let's say that this ingest session is two hours. Then a day after I go to the exercises guide and I found my self barely remembering what tools to use, what are the conditions to apply this or that concept. I'm trying to be more aware of my learning process and what to know what works for others.

Questions: Did you face similar challenges while studying? What gives you the best result after this phase of "ok, I did not internalize this yet" what is your approach to fill in the gap? Is said that blindly reviewing the sources like re-reading is a waste of time. How do you implement the cycle of do-fail-improve-do?

Thanks in advance!

I work with python and currently my development workflow could take two ways:

- Develop code that run on lambda service as 'zip' let's call it.

- Develop code that run on lambda service as 'container' with ECR.

On both cases what I regularly do is mimic EFS or S3 with local directories and launch container images 'aws-lambda environment' based. Let's say that this is not so painful, when deployed the normal, set up permissions, tune up configuration time outs and so on. But for example setting up database interactions is a pain. The connection details are retrieved from secrets service, then after deployment and running I found that a field name was wrong so again, edit the code, rebuild, re launch the lambda, event test and again caching the next bug.

For a broader context: I work on a small team of 5. We don't have a Dev-Ops role or a PM that does this kind of things like setting up development environments, all is self managed, from the coding to make it work on cloud. When I started to work, three years ago, I read about aws sandboxing, if I can recall, but was another overhead.

Final questions:

Do you implement any development for cloud workflow with quality of life tools or practices?

Is this too much for a single person and I should to start the talking about making the development set ups someone else work? (this is my first job on IT actually I don't know what other ways of working are out there).

Thanks.

I am conflicted. I really appreciate C’s potential and capabilities for learning. Although Python is my main language, I use C for my college OS and networking courses. Last time, I struggled significantly; I spent hours reading documentation, felt like I was working in the dark, and arbitrarily added header files by copying others' solutions, hoping to avoid errors. Coding felt incredibly slow. I relied on the test suites, Makefiles, and build setups provided by my teachers.

I can retake these courses in August and want to be better prepared. The boilerplate feels like 'dark magic.' Currently, I am reading K&R (Chapter 4) and doing the exercises, but it feels like I am only doing tiny things, and I still struggle. Is investing time in K&R worth it? I am improvising some details, such as GDB debugging and compilation flags. I also considered C Programming: A Modern Approach, but it seems overwhelming.

My goal is to switch from web/cloud development to low-level development (systems tools or embedded systems). I recognize the gap: in Python, everything is easy (requests.post, raise Exception), whereas in C, I must manage child processes, check return values, match types, and handle scopes and memory manually. I accept that development is slower due to these additional responsibilities and the need to reduce scope.

To refine my question: Is reading K&R and doing the exercises a good use of time to prepare for my college courses? Is there a roadmap for learning C? Is pursuing a career in C worthwhile, or is C knowledge primarily for becoming a well-rounded developer while actual work uses modern languages like C++, C#, Java, or Rust?

Feeling discomfort. Currently on my day 34. I've identified my triggers when I'm stressed or public stressors like presentations at work. Currently I'm on a hard time, I'm a bit disconnected from my wife, nothing serious just bad timing, but i find my self thinking about arousal, without motivation to do anything, and starting the laying self talking "This repression will harm you", "It's ok just for relief", "you are at risk from acting and go to talk to another girl on real life". I found a similar feeling around day 15. My hope that this is temporal and I will be on the high side of the curve maybe tomorrow or on two days. But anyone has feel something similar? How do you handle dealing with situations that before triggered the behavior that you are trying to avoid? Some mention physical activity while I will introduce it on my daily basis, I mean when you are at a situation where you can not say "ok, I will leave here and will take a 1 hour walk" Thanks!

This is the panel from a 4112 xerox printer that was disposed. I have in mind the following ideas:

• convert it to video output for a raspberry pi board.
• An usb portrait.
• A basic music player (title, playback time)
• Video output for mame emulator. (This almost like video out for raspberry).

A few things:

This screen works? - Yes was perfectly fine.

Do I have the board where this connector goes? - Yes.

Do I know anything about video protocols? - No.

Input Voltage? - 24dc

I know 0,141 about electronics but I like programming and I do a few things on C and a bit of asembly for arm so I think that I know where I'm going.

Any one could point me in the right direction?

How do I send video data to this thing?

Thanks a lot!
