I'm the developer of an Android calculator, called Algeo [1] and I wonder which part of it that makes it feel like slow/not snappy? I'm trying to constantly improve it, though UX is a hard problem.

Pytorch and tensorflow is pretty big. It implies all state of the art research code is not written in Julia, so it is a non-starter for any neural network based project.

Because it only increases high single digit each release. If they keep up the 10% improvement for the next 10 release, we will reach a speedup of around 2.5 times. That's very small, considering how Python is like 10-20 times slower than JS (not even talking about C or Java like speeds).

I always wondered where the integral sign was coming from. This gives a very simple explanation: it's just the letter 's', the shorthand for sum!

This rings so true with me. I have a side project [1] that I try to promote and it always feels hard. Where do I start? Should I post comments in random subreddits? Should I write blog posts that may nobody read in the end? Start doing ads? I think having the multiple options kinda freezes me and it is so hard to start doing something.

Congrats! It's about the same I make with Android with my app (a graphing calculator) [1]. Everyone says on Android you can earn less, I'm curious what's your experience will be.

vegesm — Sat, 16 Apr 2022 13:40:03 +0000

I don't really get the first part of your comment. You say an NN is "just" compression + kNN and does no representational learning. But finding a compression (a transformation in other words) that makes kNN feasible on the data is exactly what people mean when they say it finds a hidden representation. It is a highly non-trivial task: e.g. simple distance in pixel space between images would get you useless results.

Slightly related: I got the first C compiler restored and ported to modern C [1]. It runs on Linux and can call libc functions, though it is restricted to 32bit mode.

New comment by vegesm in "The Bitter Lesson (2019)"

vegesm — Sat, 02 Apr 2022 20:08:42 +0000

Actually, MobileNetV3 is a supporting example of the bitter lesson and not the other way round. The point of Sutton's essay is that it isn't worth adding inductive biases (specific loss functions, handcrafted features, special architectures) to our algorithm. Having lots of data, just put that into a generic architecture and it eventually outperforms manually tuned ones.

MobileNetV3 uses architecture search, which is a prime example of the above: even the architecture hyperparameters are derived from data. The handcrafted optimizations just concern speed and do not include any inductive biases.

New comment by vegesm in "Ask HN: Does targeted advertising work at all?"

vegesm — Sun, 06 Feb 2022 09:30:52 +0000

Back of a napkin calculation: showing OP 100 ads of blinds probably costs 0.1$ in the US. The cost of a blind is 100$ (I have no idea, don't live in the US). So if the probability of buying a second blind is at least 0.1% it was worth running the campaign.

The fact is, online ads are super cheap.

As others said, the active number of downloads is way lower (50k). Even then, I'm pretty bad at marketing and have no idea how to grow it or optimize the monetization.

It seems from 10 ideas 9 doesn't work and even the 10th brings only modest results.

I have an android app (https://play.google.com/store/apps/details?id=com.algeo.alge...).

It brings in right around $500 a month. It is fun to develop, especially that I can dabble into frontend and UI design which is quite far away from what I'm doing daily.

Interestingly, it used to bring in much more but the heydays of apps are over.
