I got a "Revise and Resubmit" response from the journal. Reviewer #1 wanted me to implement some baselines to compare against my method and he cited 6 papers. 5 of them did not have open-source code, and it's not like you can re-implement, train models and fine-tune someone else's approach in 2 weeks. The last one had code, for Ubuntu 14 (may its soul rest in peace), OpenCV version from the time America and Europa were connected and CUDA toolkit that was carved in stone in a cave.
I was bawling my eyes out, thinking about how many days it would take trying to Docker it to work. But then I realized the approach he cited was for RGB-D data, while I only use RGB camera. That's like letting a sniper with an M82 compete in archery....6
Do you feel your looks/attractiveness played any part in your career in tech?
I'm interested to hear the dev perspective on pretty privilege :)32
To all German Devs - can you help me out with some employment law?
I have a TV-L E13 contract in the uni. I've been travelling a lot for work lately, and the journey is always falling on my rest days (Saturday or Sunday). Can I ask for compensation for spending 7 hours in a train on the weekend?
I would not care if it was a one time thing, but it already accumulated to a lot of days....14
I am working on my passion project, on my own vacation days because my advisor did not approve it and I can't take no for an answer.
But I had 3 amazing days working with my friend and research partner, full of stupid bugs, moody hardware and a lot of nutella-covered food.
I think I am going to document some of the progress on Twitter, because it supports uploading videos. If anyone is interested in failing robots, I can share the link/handle :)10
How to step up the level of emotional torture PhD students are subjected to by academia:
In addition to the normal status for submitted papers, which are "received", "under review" and "decision pending", let's add "undisclosed"!
Which means they know about the decision, you know they know, they know you know they know, but they will still leave you hanging for an unknown period of time, bathing in acidic dread.11
I was in a Meta workshop for PhD candidates, and they spoke about some of their programs. Meta is financing (paying the tuition fees + salary) for PhD students in Oxford and UCL. Could be interesting for people who wanted to go for a PhD in the UK but could not afford it because UK's higher education system sucks.
There was also a coding interview preparation session, and it was honestly nice to hear from them exactly what they expect from their candidates.
But maybe I have positive feeling about this event just because I went to a fucking Green Day concert an hour later, and it was the best day of my pitiful life.4
Can I have one Ubuntu base update after which I *do not* need to go to recovery mode to reinstall Nvidia drivers, and then CPR pulseaudio into function?11
We got the report made by the EU committee that is assigned to evaluate our project (robotics in the service of healthcare).
I was full on trashing the reviewers for writing some seriously dumb shit, and low-key dissing my professor. Until I got to the part where they addressed the work package I was responsible for. They referred to my work as impressive and innovative, and I was like, well, maybe they're not that bad 😂10
I'm in a few women in tech groups. A woman, who is a highly experienced developer, shared that she had a conversation with her male friend, who is a startup founder. He said that his criteria for recruitment are high levels of math and physics since high school and early interest in programming (e.g. age of 10). She said his criteria made her sad and excluded.
A fellow woman developer commented that it's reasonable to feel sad when you learn your good friend is an idiot. I snorted some Monster out of my nose reading this and I'm still coughing and chuckling.
To be honest, the founder's requirements do sound super ridiculous, and I imagine his startup is made up of clones of the same guy type, wearing different shades of gray t shirts and sandals with socks.58
The newest addition to our lab - Pikachu!
We managed to overcome the weirdest pinout configuration ever on the MCU and power up the Nvidia Jetson.
Next week I'm going to make a clean install of the Jetson because there is some funky garbage there, and then I'll try to drive the little beast :)18
So the new robot (Dingo) arrived yesterday. Today I did the unboxing, and damn was it disappointing. I realized the university purchased it not from the company I recommended, and they messed up the delivery.
The robot controller was missing, and the charging cable did not match the charging station input. Like dude, you had one job!
Since the lady in administration decided to disregard my recommendation and order from a random shop, she might as well assemble the robot herself....15
I interviewed for a YouTube channel that hosts young researchers from different fields, to discuss robotics (in very simplified and people-friendly terms).
I also to managed to assemble my TD-7 drum kit remarkably fast, considering I don't have previous IKEA experience. This is why you should give opportunities to enthusiastic juniors, they might surpass your expectations :)15
My advisor thought that my MCL algorithm behaves a bit strange, so he wanted me to investigate it. I said I'd be happy to review the code because I anyway considered refactoring, and asked if I can have another pair of eyes to help me.
A more senior PhD student was assigned to help me, and by the suggestion of my advisor we tested my code against a very well-written and well-performing implementation of MCL. This implementation was written by another professor, who is a close friend of my advisor and the actual supervisor of the student assigned to help.
But this implementation was optimized for a very specific type of maps, and on the maps I worked on it just failed consistently. The student, in a misguided attempt to protect the pride of his advisor and subsequently his, wasted days adding code and fine-tuning the implementation.
In the meantime, my MCL has a stable configuration that converges on both types of maps. It behaves differently, but the outcome is about the same as the other implementation.
I am a little sick of wasting my time (week+) on someone else's attempt to reassure their ego, so I'm doing my planned research work on the weekend...1
JSON de/serializer for C++, recommendations?
I used boost serialization until now, and it's fine.
But I will need to send some stuff over REST protocol to my future-web-GUI.
I would like something that is easy to build, not bloated, and could handle class serialization.
Training the beast!
Hopefully I will submit my paper soon, and then I can share a video of the beast in action :)41
So my localization algorithm actually runs onboard my YouBot :)
My paper was basically torn apart by my professor, so I had to write some new classes and redo the whole experimental section. And all the other sections too. I resubmitted it to him after revisions, and the second iteration was way better - I'm really close to final paper level :)
I told my professor and postdoc that I will appreciate more support and positive feedback, because so far our communication was only very dry criticism. For me it's really devastating, because feeling like I constantly disappoint people just kills me on the inside.
It seems like they took it to heart, they have been nicer to me in the last few days :)6
Do you think being a great software engineer is simply hard work and passion?
Or there is also a component of natural affinity, certain personality traits, etc.47
People of devRant, how did you meet your spouse/partner, and what is their occupation?
I am just wondering how you get to actually meet people and create relationships while having an insanely intense tech career.35
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
The reason I don't have friends is because I embed Python code in C++, instead of using pybind like the Linux gods intended us to 😅
If you want to load data from Pandas DataFrame in a C++, I can put some examples on my Github.6
I was watching "hacker reviews hacking scenes from movies", and god forbid they brought a woman to do the analysis. A lot of butt hurt boys in the comments, that women left the kitchen and got into programming.
This aside, the combination of ignorance and arrogance was just wow. I mean, if you want to be a dick, at least back it up with skills.
Don't make claims about how "GUI is the single most important piece of any software". *laughing in embedded programming*24
I got the booster shot yesterday but I'm pretty sure they injected me some psychoactive drug. I had the weirdest dreams - I was have in-depth arguments with my post-doc about complexity and deep learning, and I came up with 3 different directions for my research. Also my mom was singing Despacito in the background.
My arm is dead and I can't even connect cables on my beloved robot :(7
My professor asked for some images of cool stuff I worked on for a presentation he is giving. So here is me moving fast enough to cause motion blur :) The code is using the camera to detect people, and then project the bounding box down in the lidar frame, and mask all the lidar points within that cone.
Anyway, if someone is familiar with super fast agglomerative clustering code in C++ (or even python, if it's efficient), please share it with me!7
If you have a new Alienware, I highly recommend not to try installing Ubuntu on it. I can't even describe how many levels of hell I went through to get stuff working, and how every Ubuntu base update gives me a panic attack.
From Ubuntu not installing with RAID settings, then not being able to boot in GUI mode because Nvidia drivers, to built-in keyboard, speaker and mic not working.
Praise the Ubuntu lord, now everything is working, but I still can't adjust the rgb keyboard colors :(25
I hate academia. It feels like a rigged game, where some people don't have to do even the bare minimum to have their paper accepted, thanks to their associations/connections. I just read a paper who got accepted to a top robotics conference, with no published code, no bench-marking against other methods and obviously no looking for related and previous work on that topic. I am furious!12
10/10 best out of stock message I've ever seen. "Victim of its own success" 😂
If all goes according to my devilish plan, I will get a new robot!5
A shout out to Dear ImGui developers - super amazing job! Took me 1-2 hours to figure how things work from the examples.
A few C++ files is all I needed to integrate the GUI into my project, and it was rather painless.
My UI/UX skills are poor, so the awful interface is on me :)9
TorchScript is pure pain, and Torch c++ is so poorly documented you might as well just call random functions and objdump to figure what the hell is going on there.1
I opened an Instagram account to document my work with the robot, because there is so much mechanics and dirty work and painful engineering done, which will never be acknowledged in any future paper I might publish.
For now it looks like I am doing well, since instead of dick pics from followers, I get LinkedIn requests :)7
