So I've been working on collaborative localization, which means robots in a team help each other improve their pose estimation!
We submitted a paper to a robotics conference (fingers crossed), and you can find a video from the demo here:

If someone asks me how I spent my 30s, I'll be like "oh, I waited for the Docker to build"

Woohooo, I'm going to Tokyo!
Our paper was accepted to a robotics conference. We have the pleasure of playing with tiny drones, and we get paid and rewarded for it!

Any undercover physicists/chemists wanting to shed light on the LK99 drama?

Men of DevRant, do you think it's OK to try and pick up women on LinkedIn?

A guy, who claimed to see me on Bumble, message me on LinkedIn about "wanting to get to know me". My rarely used Bumble profile doesn't have my family name, nor my real job title or my workplace. Which means the dude also had to indulge in some high-level stalking to get to my LinkedIn profile.

I've seen some cute guys on LinkedIn, that if we had a pleasant interaction in a conference for example, I would totally ask them out. But it never crossed my mind to even try and chat them up on a professional platform.

Am I too conservative or is this just inappropriate?

I was interviewed by the Clearpath Robotics about my experience with using their Dingo-O platform.

The institute where I did my B.Sc is under a ransomware attack, and I'm bracing myself for the publication of my embarrassing transcripts, and possibly the even more humiliating scans of my exams 🤣
Oh, well.

How geeky you are from 0 to getting merchandise from Intel?

We had to review a design document written by our partners, and have it approved by end of Dec.
While I was reading it, I noticed that we committed to a module I wasn't familiar with. I asked the other two lab mates, and they had a surprised Pikachu face.
So we called the boss to discuss this. And it dawned on him that we committed to a task that was assigned 20 months of work, but nobody started working on it. And considering Holidays and other commitments, we had like 3 months to do it from scratch and deliver.
My advisor panicked, and his first response was to assign this task to me.
I politely declined, and after digging in my email box, found that he actually assigned the task to someone else. So I showed it to him.
Thinking I would save him after he treated me badly for nearly 2 years was hilarious. For a better manager, I would have definitely agreed to assist. But as it is now? I'll be eating cookies while I'm watching the project burn.

My third paper got accepted, doing localization with this cute baby in the picture. Had a lot of fun collaborating with a good friend of mine from ETH.
My advisor declines every request I have, and then ignores me most of the time. No wonder the motivation in the lab is lower than the Dead Sea.
I have no words to describe how much I hate every second of my existence, but simultaneously I refuse to change my toxic circumstances so I have only myself to blame. Cheers.

Getting zero encouragement or positive feedback from my boss is really killing me from the inside. There isn't even a negative feedback. There's absolutely nothing.
PhD is such a lonely path as it is, and being ignored by your advisor is just...soul-crushing.
I did a collaboration with my friend from another lab, and even though her lab is bigger and crazier than ours, her professor found the time to compliment our work and even told us he will present it in a presentation he gives in Meta. Really, it's not that hard to say a kind word here and there.

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....

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 :)

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....

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 :)

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.

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.

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?

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 😂

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.

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 :)

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....

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 :)

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...

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.
Shoot!

Training the beast!
Hopefully I will submit my paper soon, and then I can share a video of the beast in action :)

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 :)

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.

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.

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 promising
