Fuck the U.S. government.
Fuck the UK and Australia and all the other governments for taking advantage of the crisis of the last two years to get more power and money for their elites.
Fuck them all for starting COVID with their unsanctioned and unethical “gain of function” lab experiments and creating so much chaos that nobody really has a chance anymore at living the life they had dreamed of or so carefully planned for.
Fuck them for the out of control spending and money printing and inflation and even messing around with trying to regulate and tax crypto so we don’t have any kind of escape valve to live a normal, happy life.
Because of them, I can’t even enjoy my time off work. Even if I could plan a vacation that wouldn’t have to be canceled due to an outbreak or resultant supply chain issues, I can’t travel without severe restrictions that make it miserable and not worth the trouble.
Fuck them for making everyone into stupid monkeys fighting over opinions about data that is incomplete, misunderstood, misrepresented, or downright fixed toward a specific pharma-fascist authoritarian outcome.
And fuck them especially for being hypocrites and going to parties and generally not following their own rules they made for us when they think we’re not watching, and then persecuting and prosecuting us when we dare do the same.
Fuck ‘em all. I’m so done.21
Lisp code was live-debugged and fixed with REPL on a spacecraft 100 million miles away
“An even more impressive instance of remote debugging occurred on NASA's 1998 Deep Space 1 mission. A half year after the space craft launched, a bit of Lisp code was going to control the spacecraft for two days while conducting a sequence of experiments. Unfortunately, a subtle race condition in the code had escaped detection during ground testing and was already in space. When the bug manifested in the wild--100 million miles away from Earth--the team was able to diagnose and fix the running code, allowing the experiments to complete. One of the programmers described it as follows:
Debugging a program running on a $100M piece of hardware that is 100 million miles away is an interesting experience. Having a read-eval-print loop running on the spacecraft proved invaluable in finding and fixing the problem.”
Sometimes I wish I was driven by positive reasons, and not by self-loathing and sense of worthlessness. I didn't have an actual vacation for over 3 years.
I am now in Thailand with my parents, and I am working my ass off to meet IROS/RAL deadline instead of chilling. The urge to continue working is really compulsive. I am very tired.
On a brighter note, the early experiments I ran look promising9
"So Alecx, how did you solve the issues with the data provided to you by hr for <X> application?"
Said the VP of my institution in charge of my department.
"It was complex sir, I could not figure out much of the general ideas of the data schema since it came from a bunch of people not trained in I.T (HR) and as such I had to do some experiments in the data to find the relationships with the data, this brought about 4 different relations in the data, the program determined them for me based on the most common type of data, the model deemed it a "user", from that I just extracted the information that I needed, and generated the tables through Golang's gorm"
VP nodding and listening intently...."how did you make those relationships?" me "I started a simple pattern recognition module through supervised mach..." VP: Machine learning, that sounds like A.I
Me: "Yes sir, it was, but the problem was fairly easy for the schema to determ.." VP: A.I, at our institution, back in my day it was a dream to have such technology, you are the director of web tech, what is it to you to know of this?"
Me: "I just like to experiment with new stuff, it was the easiest rout to determine these things, I just felt that i should use it if I can"
VP: "This is amazing, I'll go by your office later"
Dude speaks wonders of me. The idea was simple, read through the CSV that was provided to me, have the parsing done in a notebook, make it determine the relationships in the data and spout out a bunch of JSON that I could use. Hook it up to a simple gorm golang script and generate the tables for that. Much simpler than the bullshit that we have in php. I used this to create a new database since the previous application had issues. The app will still have a php frontend and backend, but now I don't leave the parsing of the data to php, which quite frankly, php sucks for imho. The Python codebase will then create the json files through the predictive modeling (98% accuaracy) and then the go program will populate the db for me.
There are also some node scripts that help test the data since the data is json.
All in all a good day of work. The VP seems scared since he knows no one on this side of town knows about this kind of tech. Me? I am just happy I get to experiment. Y'all should have seen his face when I showed him a rather large app written in Clojure, the man just went 0.0 when he saw Lisp code.
I think I scare him.12
Most successful? Well, this one kinda is...
So I just started working at the company and my manager has a project for me. There are almost no requirements except:
- I want a wireless device that I can put in a box
- I want to be able to know where that device is with enough accuracy to be able to determine in which box the device was put in if multiple boxes were standing together
So, I had to make a real time localization system. RTLS.
A solo project.
Ok, first a lot of experiments. What will the localization technique be? Which radio are we going to use?
How will the communication be structured?
After about two months I had tested a lot, but hadn't found THE solution. So I convinced my manager to try out UWB radio with Time Difference Of Arrival as localization technique. This couldn't be thrown together quickly because it needed more setup.
Two months later I had a working proof of concept. It had a lot of problems because we needed to distribute a clock signal because the radio listeners needed to be sub-nanosecond synchronous to achieve the accuracy my manager wanted. That clock signal wasn't great we later found out.
The results were good enough to continue to work on a prototype.
This time all wired communication would be over ethernet and we'd use PTP to synchronize the time.
There was a lot of trouble with getting the radio chip to work on the prototype, ethernet was tricky and the PTP turned out to be not accurate enough. A lot of dev work went into getting everything right.
A year and 5 hardware revisions later I had something that worked pretty well!
All time synchronization was done hybridly on the anchors and server where the best path to the time master was dynamically found.
Everything was synchronized to the subnanosecond. In my bedroom where I had my test setup I achieved an accuracy of about 30cm in 3d. This was awesome!
It was time to order the actual prototype and start testing it for real in one of the factory halls.
The order was made for 40 anchors and an appointment was made for the installation in the hall.
Suddenly my manager is fired.
Ehh... That sucks. Well, let's just continue.
The hardware arrives and I prepare everything. Everything is ready and I'm pretty nervous. I've put all my expertise in this project. This is gonna make my career at this company.
Two weeks before the installation was to take place, not even a month after my manager was fired, I hear that my project was shelved.
"We're not prioritizing this project right now" they said.
It would've been so great! And they took it away.
Including my salary and hardware dev cost, this project so far has cost them over €120k and they just shelved it.
I was put on other projects and they did try to find me something that suited me.
But I felt so betrayed and the projects we're not to my liking, so after another 2-3 months I quit and went to my current job.
It would've so nice and they ruined it.
Everything was made with Rust. Tags, anchors, RTLS server, web server & web frontend.
So yeah, sorry for the rambling.5
Accuracy 0.90 achieved so easily, makes me wonder if I've done something wrong. Lol.
My neural net models are the only things in my life doing well. I think I chose the right career. Lol.
Rerunning experiments is not fun. But getting better results is really... Ego stroking.26
> Going to get another paper published (hopefully) once my exams end
> Got a intern, not a lot of money, ₹2L≈$2.6k per month for 2.5 months
> Will get a Mac from company for the intern(probably not new, and most likely will be taken back soon after the internship)
> Planning on entrepreneurship after getting a degree
Ohh and the rant:
1. Fucking sent me a 2 page list of links as "pre reads for internship" during my exams -- and intern will start soon after exams
2. Have missed 3 paper submission deadlines till now, hopefully will run more experiments on time this time and finally get that paper submitted (on 15th May)
You people ever heard of the BeamNG game? The detailed vehicle physics simulation...
The question that has been bothering me lately is: why the hell are BeamNG videos so addictive 🤔 I get those videos sometimes in my YouTube feed; and once I start watching those, I usually cannot stop.
Like, the car with parts stripped from it over time. Or the truck carrying an ever-increasing number of rocks uphill. And the crashes, of course
But the question is: what do I find so fascinating about those videos? Why is it so hard to stop? On the surface, it is nothing special. Just some silly experiments involving vehicle physics
Weird; so weird... ☁️2
commodore amiga 500, when I was 5 or 6.
what was the very first thing on it that i experienced, i don't know, but some things i remember:
Cannon Fodder 2
A-Train, a game that i played for months, it utterly fascinated me and i was utterly unable to keep my company afloat, because i was utterly unable to understand how the mechanics of the materials moving around worked (i still don't, actually, but in a different way)
some Apache simulator, which took us (me and father) literally a week to figure out how to get into the actual game from the main menu stylised as a military office. it took us several days to even realize it's the menu.
the Lotus Esprit 2 game, which we played regularly.
some Airbus simulator where i took two weeks of trial and error to figure out how to take off, without manual.
some experiments with midi sequencing and notation music programs.
how every two months, dad came with a 20page long list of programs and games from some pirate seller, which we would go through, mark stuff that sounded interesting (going by name only), then he would send it by post to him, and after a week, we would go take a package from post office full of floppies, literally like 200, and the next two or three weeks, we would be trying all of it out, seeing what the things we got were about, putting the good ones on one pile, the boring ones on another (cheap floppies for use)...
ah the magical times of wonder and exploration...2
A year ago I built my first todo, not from a tutorial, but using basic libraries and nw.js, and doing basic dom manipulations.
It had drag n drop, icons, and basic saving and loading. And I was satisfied.
Since then I've been working odd jobs.
And today I've decided to stretch out a bit, and build a basic airtable clone, because I think I can.
And also because I hate anything without an offline option.
First thing I realized was I wasn't about to duplicate all the features of a spreadsheet from scratch. I'd need a base to work from.
I spent about an hour looking.
Core features needed would be trivial serialization or saving/loading.
Proper event support for when a cell, row, or column changed, or was selected. Necessary for triggering validation and serialization/saving.
Custom column types.
Embedding html in cells.
Optional but nice to have:
Changeable column width and row height.
Drag and drop on rows and columns.
Right click menu support out of the box.
After that hour I had a few I wanted to test.
And started looking at frameworks to support the SPA aspects.
Both mithril and riot have minimal router support. But theres also a ton of other leightweight frameworks and libraries worthy of prototyping in, solid, marko, svelte, etc.
I didn't want to futz with lots of overhead, babeling/gulping/grunting/webpacking or any complex configuration-over-convention.
Didn't care for dom vs shadow dom. Its a prototype not a startup.
And I didn't care to do it the "right way". Learning curve here was antithesis to experimenting. I was trying to get away from plugin, configuration-over-convention, astronaut architecture, monolithic frameworks, the works.
Could I import the library without five dozen dependancies and learning four different tools before getting to hello world?
"But if you know IJK then its quick to get started!", except I don't, so it won't. I didn't want that.
Could I get cheap component-oriented designs?
Was I managing complex state embedded in a monolith that took over the entire layout and conventions of my code, like the world balanced on the back of a turtle?
Did it obscure the dom and state, and the standard way of doing things or *compliment* those?
As for validation, theres a number of vanilla libraries, one of which treats validation similar to unit testing, which seems kinda novel.
For presentation and backend I could do NW.JS, which would remove some of the complications, by putting everything in one script. Or if I wanted to make it a web backend, and avoid writing it in something that ran like a potato strapped to a nuclear rocket (visual studio), I could skip TS and go with python and quart, an async variation of flask.
This has the advantage that using something thats *not* JS, namely python, for interacting with a proper database, and would allow self-hosting or putting it online so people can share data and access in real time with others.
And because I'm horrible, and do things the wrong way for convenience, I could use tailwind.
Because it pisses people off.
How easy (or hard) would it be to recreate a basic functional clone of the core of airtable?
I don't know, but I have feeling I'm going to find out!1
So, like, why doesn't Java let me do manual memory management? In C# if I want to screw up the code-base and everyone that comes after me with my half-informed experiments it totally lets me.21
