tldr: I am a human with dreams and doubt.
At the Univeristy you end your course of study with a thesis, and there are two kind of thesis: compilative and progettual.
Compilative means that you study something and then make a report about it. Usually I see that this kind of thesis is done by people who just want to end the course.
Progettual means that you actually develop something, maybe driven by a professor, doing something new, or try something in a different way to see if it works... This is for the good guys.
but mine does not fit any of those.
I studyed a lot about some topics, I learned to use the existing tools, I learned to decide which tool is better and when. I learned the open problems in the field. And my thesis is an analysis for a solution for some of them. I did not develop a project, but I didn't just study something. And I am giving the base for a much bigger project.
And I did everything on my own, the prof who is supposed to drive my work let me go on, and I never really asked for his help.
Obviously everything is a mess, the thesis describes broadly a large range of things, who are outside my course, and I am just copying from here and there (avoiding wikipedia because I would be ashamed of that) (I mean, I avoid wikipedia and jump directly to the source).
I actually made a little project from the conclusion of my analysis, but it is more of a mistake than other.
And maybe I am writing this to grow my pride, and avoid depression. To tell me I am not a total failure. Or maybe am I really good as I dream to be? (because that is how pride works, doesn't it?)
I intented a new kind of thesis! Ah!
I will see the prof on wednesday and the deadline is on saturday! I will let you know!
and oh!I am writing it in english so you can read it!
Just kidding, I don't give a fuck about anything anymore, I just want to end this mess, and in english is easier to copy.
I learned from this big mistake of a thesis, next time I will make sure that the prof drives me, because I am 20 and cannot do an analysis such complex on my own.
becauuuuseeee yes! There will be a next time! I am graduating in december, but I am following the master courses since september! In january the first exams! I am practically already thinking about the next thesis. Suggestion on other mistake to avoid?
Did you know James Joyce and the stream of consciuosness? Well, here it is.
I may have spelled something wrong, I hope everything is undestandable.
wow, 2500 characters of rant, I am improving writing the thesis in english!
my university offers an exchange with a university in Bielefeld!
I have heard lot of you live near it!
what do you think about it?
german people: let's just assume Bielefeld exists...8
Lately I am working using icestorm!
I know very few people know it, mainly beacuse not a lot of us works with FPGAs.
It is foundamental for the open source scene because is the only FOSS that gives you the ability to "compile" for FPGAs, otherwise you would have to use some proprietary tool.
People are building lot of things on top of that, and I hope more people start workin with FPGAs: dealing with them is still quite hard, especially if compared with MCU programming.
I am sure that in very few years we will see something very interesting in that field.4
I don't see anyone linking this so I am doing it!
ad block can be flanked, it is nothing strange, but some poeple have made a very good analysis on this.
pi-hole should still work, for what I can tell
I am in love.
I am in love with all the guys and girls working at Microchip support.
I am the kind of user that does not really understand what he's doing/what he wants to do, so I am constantly stuck in stupid configuration errors or looking for impossible solutions, yes I am THAT kind of a user...
Here is a PWM working, a support guy spent some minutes telling me that I have to connect to the right pin.
Ok, he had to tell me twice.😳
Thank you, it may have taken me days to find out this.
They does not know, but there is a HUGE amount of decreasing dumb question incoming 😈
Please be kind with me, and don't get mad when things will get serious, I will probably bring hell in your office, I am very sorry for that...
Still, thank you for helping the dumbest learner-by-mistake that doesn't know how to recognize a mistake.
I can't write this in the ticket system, I hope someone of you use devRant! (atsame54 office, I am talking with you!)
You are my stack overflow, and the project I will develop with your help is quite the only thing left before my graduate.
I will owe you so much beers, love you guys!!!
Today I watched "the birth and death of js":
Here Gary Bernhardt talks about compiling executables to asm.js and about running the compiled files using a js interpreter that can be included in the kernel.
Eventually, some responsibility can be moved from the kernel to this interpreter, responsibility like virtual memory and trap management.
This speech aims to be fun, so not everything should be taken seriously...
...this trick seems to be a nice idea, and projects like Node OS work likewise.
So now, would you even consider this? Or is it just something that will be nothing more than craziness of a mad man?1
***JUST BECAUSE SECURITY***
My father deleted the email with the credential for our ISP (pppoe: username and password), and I need it to connect a router.
Just called the tecnical service, after a couple of minutes they gave it to me.
They sent to me both username and password.
Asking me where to send (which mail).
I DIDN'T EVEN KNOW HOW IS CALLED THE CREDENTIAL I NEED.
Obviously, I just had to say the accountholder of the bill.
Now I am super scared, i can virtually access any account.8
Currently trying to make a multi boot machine, with a lot of linux distros inside, like debian, fedora, gentoo and arch.
I know I will have to format everything a lot of time, because of stupid mistakes, I want to try to put /home in common, and play with some more SSD, and to put a preempt_rt patched kernel somewhere.
I am starting from debian,
Format counter: 3
Reason 0: because i need to install at least once...
Reason 1: I am stupid
Reason 2: I disconnected the SSD,to connect a disk with windows. Now bootloader doesn't find any os in the SSD anymore... still no clue, and in case of doubt: give windows the fault 😠😠😠
DAMN YOU WINDOWS, how did you find that I want to use debian? What did you do to break it?? (Despite it wasn't even connected?!?)
I have checked everything about secure boot, and I am sure it is disabled...
And every search online gives results about dual boot, but it is not my case... :/
There are 10 kind of people:
-those who will not get this at all
-those who expected 10 to be in base 10
-those who are used to the joke with 10 in base 2
-those who will think 10 is in base 6
-those who will add kinds of people and say that my interpretation of "10" was wrong (a subset of those will make the second group be rigth)
-those who will help me to find a way to recursively break this joke (pls, help, i can't find it... 😭😭)3
You are all invited to the SPI-Party!!!!
*crying.... this is not my job, i am less than a noob around here 😭😭*12
There are only 10 kind of people!!!
- the ones that don't know in which base 10 is. (In my case is unary base)5
Short story for the one interessed in the image: when we change idea we change the whole idea. And it is likely to happen very often. Sometimes twice a day, every day, for a week.
I am hopeless:
I am an IT university student, i know how to program and how to search for a fucking manual, but i am dealing with eletronics and PCB...
I have to make the firmware for a board (atmel things) and it have to talk via spi with some other devices (it is slave of one, and master for all the others(i will use two spi channels)), this should be easy...
I am have no senior to ask to, all i have is google and i found problems in every thing i try to do, every - fucking - single - one!!!! I know that the solution is always of the "you have to plug it in" type, but
NEITHER GOOGLE IS BEING OF HELP!
Let me explain this morning pain:
i can't add libraries in atmel studio, something wrong with the asf wizard, i have only found a tutorial that says what buttons press to solve my problem... I DO NOT HAVE THIS BUTTONS!!!
And the library i wanted to add is the one to make the board talk with the computer on his COM port... (And have some debug message...)
And the wizard gives problem because i created the project using an online atmel tool...
YES, i tried to create a project with asf and then add the files given by the online tool.... THEY DO NOT COMPILE, I SHOULD HAVE TO MESS WITH A 400 LINES LONG MAKEFILE, that is anything but human readable...
I haven't even look for anything spi related this morning
I am even forced to use windows, because every question in the forums, or every noobbish tutorial is based on it...
And then i find the tutorial with the perfect title, holy shit this is the thing i truly need!!!!! It says how to open a file. And then stops. WHAT ABOUT THE THING YOU WERE TALKING ABOUT IN THE TITLE??????
This project is the upgrade of a glue-pump based on an atmega328 (arduino uno processor), that is currently being produced and sold by our "company" .... .... That is composed by me and the boss.
He is a very nice and and smart person, he tries to give me ideas for the solution, if i cannot find out how to do something we can even change a lot of specifics of the project (the image shows our idea-change) and every board has some weeks of mornings like the one described above (i work only in the morning).
I am learning a very lot of things...
But the fact that every thins i try fails is destroying me, what would you do in my place?
Ps. Lot lf love for the ones who made it until the end <36
I am reading lot of rant about Windows and dual boot...
I am using two disks and my hand to switch from one to the other.
What can be the advantages of dual boot? (Other than keeping your hands free)3
Have you seen the new telegram "istant view"??
I like the update they are making, expecially this istant view... Telegram can became the app for everything!
What about making a template for devrant on telegram istant view?
In next weeks i will try to do it in free time!2
I like devrant!!
I put a link on every programmer oriented facebook group i am in!!
Hopefully some new italian ranter will join the party!5
