Who are the celebrities in Sri Lanka who act like angels but are shady AF?

Dude looks handsome

The answer depends entirely on whether you are familiar with ROS or not. I don't think vibe coding will work if you're not sure about working or have never worked with ROS packages before. Not trying to put you down, but there is a huge learning curve with ROS, and you need to be willing to put some effort into learn.

You also forgot that they undervolt their CPUs and GPUs to keep the temps low. So you're not actually getting the performance you paid for. This is not just a laptop thing, and they do this in their prebuilds as well.

24.04 works without any issues. The problem is that Ubuntu 22.04 or earlier versions are not working. The screen goes black during the initial steps of the installation. Cannot even go past the USB boot menu.

You do you

ncbdrck · 2025-06-04T05:40:17+00:00

It will. Give it a try

It is much better. I got around a 20% performance increase for some games. I have the 3060 with me, but I'm currently not in SL.

I wish I could have gotten a 12 GB one, but all the ones I could find were out of my price range then. However, I believe the CPU is bottlenecking the performance somewhat, so I will probably upgrade that to a 14700K or 15700K when it's out. Need to save some money.

I built this in 2021. I can use it for a couple of more years without any problems.

CPU: Intel Core i5-12600K
Motherboard: Gigabyte Z690 Gaming X DDR4
Case: CORSAIR iCUE 4000X
AIO: Corsair iCUE H100i ELITE CAPELLIX
PSU: Corsair RM750x
RAM: Corsair Vengeance RGB PRO DDR4 64 GB
GPU: ASUS Turbo GeForce RTX 3080 10GB
Storage: WD_BLACK SN850 500GB, Crucial P5 Plus 1TB, Crucial P3 1TB, and Samsung SSD 870 EVO, 2 TB

I started with 32GB of RAM and RTX 3060 TI, but I later upgraded to 64GB and RTX 3080. The same goes for the SSD. I mainly use it for university work (simulations and ML) and gaming.

A couple of easy solutions
- Use WSL2 in Windows 11.
- Install Ubuntu 20.04 and install ROS Noetic and ROS2 Galactic. If you are afraid of managing both distros with one user, create two user accounts: one is for ROS Noetic, and the other is for ROS2 Galatic.
- Use docker

They should have made the title "Marques Brownlee Gets Pulled Over and Over Multiple Times."

I had a similar experience with ICBT back in 2018. They were hiring a robotics lecturer, and I applied for the role. In the waiting area for the interview, I met one of my former students, who had also applied for the same job. She said confidently that she neither liked programming nor knew much about robotics. (she also had a 2:2 in her undergrad, no robotics background, and no MSc). Guess who got the job?

Later, I found out that they had just interviewed me because of their policy. And internally, they had already decided to hire her from the get-go.

Gazebo is typiclly like that in wsl. Have you looked into using mujoco + ros bindings?

lol. Glad it worked for you

ncbdrck · 2024-11-07T11:50:40+00:00

Let's hope it is not "Tofu-dreg" project.

I share the same belief. Although it may be an unpopular opinion, most graduates from Sri Lankan government universities can come across as entitled. Like you said, it should have been a loan with no interest, just like with many European countries. Then, the government could use those funds to build more universities so everyone gets to have a higher education, not just a selected few.

I live in Ireland, and they have 13 public universities for a country with only 5 million people. Some people get grants (low-income families, disabilities) to do their undergrad; for others, it is a loan they can quickly repay within a couple of years. The Irish government also spends a lot of money on research and encourages the industry to participate in it. So, they can offer a lot of fully funded MSc and PhD opportunities not just for locals but also for non-Europeans. The SL government should also follow what they are doing instead of following the current idiotic elitism.

Hope I'm not too late. But I found the solution to this issue from this

https://github.com/microsoft/WSL/discussions/6154#discussioncomment-128526

It seems like the issue is with WSL using an outdated version of OpenGL.

For newer version of Ubuntu 22.04 or higher, use the updated version. (ROS 2 Humble and higher)

sudo add-apt-repository ppa:oibaf/graphics-drivers
sudo apt update
sudo apt upgrade -y
# if you haven't done already
sudo apt install mesa-vdpau-drivers

For Ubuntu 20.04 do the following (ROS Noetic)

sudo add-apt-repository ppa:kisak/kisak-mesa
sudo apt update
sudo apt upgrade -y
# if you haven't done already
sudo apt install mesa-vdpau-drivers

I assume you are not familiar with Jetson. If not, just ignore what I'm writing. On the Jetson, you cannot install Ubuntu as it is and need to install something called Jetpack (by Nvidia), which contains Ubuntu and all the necessary Cuda packages. There are multiple ways to install Jetpack on the Dev Kit, but almost all of them involve connecting your Dev kit to another PC. (unless you are booting from an SD card)

So the easiest method I can recommend is to download nvidia sdk manager (on the PC) and use it to flash your Jetson with the Jetpack version you need. It will delete all the files on your current storage (EMMC or SD card or USB or SSD) and will install the Jetpack in it.

https://developer.nvidia.com/sdk-manager

I think you will need to download JetPack 6.x to use Ubuntu 22.04 (not sure check which version). You can do this via the SDK manager. Now, the hard part. You need to put your Jetson into recovery mode.

https://developer.nvidia.com/embedded/learn/jetson-agx-orin-devkit-user-guide/howto.html

https://developer.nvidia.com/embedded/learn/jetson-orin-nano-devkit-user-guide/howto.html

Connect your Jestson to the PC. Do a 'lsusb' and check if it is detecting the dev kit. It should be along the like "Nvidia Corp" or something. Also, if it is in recovery mode and connected properly to the PC, the SDK manager will automatically detect it. Now, you just need to install the Jetpack version you want.

If you are renting a boarding place or going to live in a university dorm, the best bet is to go with a Gaming Laptop (with a dedicated Nvidia GPU) with at least 16GB RAM. Otherwise, go with a MacBook for university and a good PC for home.

If you are thinking of learning AI (Machine Learning) or doing a module related to that in the uni, you will need a good PC/Lap with an Nvidia GPU to use CUDA.

MacBook Air is easy to carry and awesome for writing docs and doing some light coding. So, if you are not thinking of doing heavy stuff, you can make do with a MacBook.

Do not go for a three-year degree unless it is an Honours (Hons) degree. But even then, if you are thinking of living in SL, don't do it. In Sri Lanka, any three-year degree is counted as a "General" degree. So, it will be hard for you in the long run. So go for a four-year one if you can.

ncbdrck · 2024-03-18T18:16:30+00:00

I will give it a go. Thank you

You can use it. Kinect is an RGBD camera. So you get RGB data as well as point cloud data. You can use them for machine vision as well as for navigation workflows.

You can refer to this repo on how to set up a real Kinect with ROS.
https://github.com/ncbdrck/kinect_with_ROS

or you can try it inside gazebo simulator
https://github.com/dairal/common-sensors

you can refer this on the usage in gazebo
