were you using single cycle waveforms or longer samples? in the former case, I guess there's not much to it, you just cycle through the waveform (in which case the waveform you choose would usually start and end at a zero crossing by c

Whenever I feel like doing that I just use "uv pip" and pretty much do the same things I'd do when using pip to messily install things in a typical virtual environment.

There's definitely a "rich get richer" effect for academic papers. A highly cited paper becomes a "landmark paper" that people are more likely to read, and hence cite - but also, at a certain point it can also becom

Ah, so that's why the camera seemed familiar, I have a couple of the luxonis cameras around the office :). Re: kiwi, those are good points. Thank you for the answer!

Hi, I am currently considering a Lekiwi build but I am intrigued by Mars. Outside of the need for external compute, what issues did you find with SO101 and Kiwi? Also I am curious about a couple of the parts, if you don't mind sharing

Seems like a corporate version of the "buy vs build" question. If it's true that the goal is to become more approachable to students and hobbyists (which personally I think would be a good idea) - then Qualcomm must've e

I feel like the raspberry pi pico is more of a competitor to the arduino than the raspberry pi - there's quite a few applications where having a whole linux operating system is a hindrance compared to running on bare metal, especially

This is a great book - learned a lot from the first edition back in the day, and got the second edition as soon as it came out. It's always fun to just leaf through a random chapter.

Yeah, that's a good point. I was thinking in the US context, but I also have some experience for the academic evaluation process in Chile, and there were similar issues to what you were describing. The "bean counting" part of

Depends on who is doing the "careers valuing" and how closely they're looking. At a coarse level, especially for jobs in industry, venue is a pretty simple (but obviously imperfect) indicator for quality. If you've manag

Just one data point, but if it's as nice to use as their open source tools and not outrageously expensive, I'd be a customer. Current offerings for private python package registries are kind of meh. Always wondered why github does

I had a similar thought, but at the same time, if people were mandated to use Windows or MacOS then that would also pretty much lock you into their respective window managers. I guess it feels more restrictive partly because it's more

The few examples they show do look pretty good for a wifi-based method, although who knows how cherry-picked they are. I wonder how much the "SLAM" part is contributing and how sensitive that is to the sensor quality on the phone.

This sounds pretty similar to CDE, which I see they cite in the paper. Back in the pre-docker days I remember using CDE a few times to package some C++ code to run on some servers that didn't have the libraries I needed. Pretty cool to

I was going to mention this sounds like the idea behind adversarial approaches, which I guess go all the way back to game theory and algorithms like minimax. They're definitely used in the control literature ("adversarial disturba

You can examine the code of zxing-cpp (which is fairly nice IMO) for a simple, "classical computer vision" approach to this. It's not the most robust implementation but it is pretty functional. But in general, you can divide

You can roughly divide barcode reading into a "frontend" and a "backend". The backend is the most well understood (but not necessarily trivial) part: you take a binary image, with each pixel corresponding to one little

I've found myself adopting this philosophy for a specific use case: monitoring ML training jobs. It's pretty common to see people output training metrics (loss, validation accuracy, etc) every N batches, iterations or epochs. And

I don't know if there's an earlier source, but I'm guessing Matlab originally popularized the `imread` name, and that OpenCV (along with its python wrapper) took it from there, same for scipy. Scikit-image then followed along

I'm not sure I quite understand what you're aiming at with these questions, but there are certainly techniques in ML based on thinking of functions as vectors. The first one that comes to mind is Anyboost [1], which views boosting

"why didn't we think of this sooner?", asks the article. Not sure who the "we" is supposed to be, but the robotics community has definitely thought of this before. https://robo-affordances.github.io/

Like the other commenter said, their retail price is $2000. In the used market, they are going for about $1400-1500 based on reverb.com stats. So at least compared to those prices, $1400 new is a decent deal. And for what it's worth, t

Yeah, the article was painting with a bit too of a broad stroke IMO, though they did briefly acknowledge "special exceptions" such as satellite or medical imagery. It's very application-dependent. That said, in my experience

There's been a huge amount of work on image transformers since the original VIT. A lot of it has explored different schemes to slice up the image in tokens, and I've definitely seen some of it using a multiresolution pyramid. Not

Slicing up images to analyze them is definitely something people do - in many cases, such as satellite imagery, there is not much alternative. But it should be done mindfully, especially if there are differences between the training and tes

$8000 also seems pretty cheap for 2PB of traffic? Looking at google cloud storage egress rates, $0.02/GiB (which is on the lower end, since it depends on destination) would be about $40k for 2PB.

Honestly, I think that if in 2020 you had asked me whether we would be able to do this in 2025, I would've guessed no, with a fairly high confidence. And I was aware of GPT back then.
