liquidmetal··on PyTorch on Apple M1 MAX GPUs with SHARK – faster than TensorFlow-Metal
How do your benchmarks compare against CoreML?
liquidmetal··on Papers with Code
In my experience there are many lesser significant hyperparameters that can impact performance when going from the released code to your personal favorite framework.

Nothing you can't figure out by reading source code of the two frameworks or by reading the documentation closely.

Generally, people don't seem to care about reproducing exact metrics - as long as it is close enough they're happy. You need to dig a bit deeper if you want the full quality.

Permanent residents are also subject to the expatriation tax AFAIK.

Chicago Tribune doesn't show the website in India?
liquidmetal··on Comixify: Transform video into a comics
Something similar we did for an internal Microsoft hackathon in 2017. https://utkarshsinha.com/blog/microsoft-oneweek-hackathon-20...
liquidmetal··on Google Cuts Its Giant Electricity Bill with DeepMind-Powered AI
+1

There can be hidden variables that the PID system failed to account for. Workload distribution over time, temperature at the time of day, heat leaking into the datacenter, etc. I'm not sure if a PID based controller would account for such things.

What remains to be seen, however, is whether these manipulations keep the machines working at similar efficiencies and if they fail at similar rates as before turning on the control system.

Tangent here - self-awareness is an evolutionary cul-de-sec? Do you have any further reading suggestions on this?
liquidmetal··on The Three Cultures of Machine Learning
And then submit a paper to the same conference from where we collected the papers.
liquidmetal··on Farbfeld – A suckless image format
The fact that this file format doesn't enclose the AdobeRGB vs sRGB information is a deal breaker.

A lot of computer vision research datasets uses a similar file format - so I can see its use there. But things like movie creation, publishing, etc will probably never adopt this.

liquidmetal··on Ask HN: What's your favorite online course?
Great suggestions here. Have you looked at this repository: https://github.com/prakhar1989/awesome-courses

It's a collection of some of the best courses on the internet. The topics covered is quite diverse - but mostly related to computer science.

liquidmetal··on Hugo – Golang static site editor
I use hugo on my personal blog at the moment. http://utkarshsinha.com/

A few things I've found interesting are:

- Getting the layout just right takes a bit of tinkering (I mean the layout, theme and include file locations - not the CSS).

- The `hugo` executable is just perfect. hugo server --watch is all you need (plus it's super fast!)

- Also, I'm not a Ruby person. I don't need a whole Ruby ecosystem working on my machine just to parse some markdown.

liquidmetal··on Visa Systems Issues
They probably already have you fingerprints.
liquidmetal··on GitHub's down?
Not again.
liquidmetal··on What every computer science major should know (2011)
No machine learning? Really?

It seems like for every problem out there - at least some tiny bit can be solved by machine learning.

General pattern recognition (identifying peaks, predicting disk outages, etc) at the minimum seems like a requirement that will show up in the next few years.

liquidmetal··on How to Generate Millions of HTTP Requests (2012)
On an unrelated note, that website looks so 2011!
liquidmetal··on Graphical Linear Algebra
Seems like a good idea. I would have liked this better if it covered harder theory. Khan Academy's linear algebra section is pretty good. I find it very long, though. Text + graphics wouldn't have that limitation.

My suggestion would be - take mathematics required by game development and explain how that works - collisions, intersections, visibility, rotations. All the juice is right there!

liquidmetal··on Ask HN: Who's your role model?
John Carmack. He's consistently at the edge of technology - whether it is game engines or avionics. His insights are excellent and can often be used in other areas of engineering / software development.
liquidmetal··on Programming Computer Vision with Python
I used to write for http://aishack.in/ - it's in C/C++ and covers most basic topics in computer vision.
liquidmetal··on GitHub is blocked in India
I've been using the Google DNS server for a while now - so Github worked just fine for me. However, gists went down for a couple of days.

Gists, pastebin and imgur are still down for me every once in a while. Refreshing it ~4-5 times seems to make it work. This seems to suggest there's something more than just DNS at play here.

liquidmetal··on Ask HN: What project are you working on over the holidays?
I'm experimenting with AndroidStudio and getting the NDK to work. Once I have this figured out, fun times lie ahead!
liquidmetal··on Show HN: Shift for Android – Photo filters made by you
How do I add a new control point? Are you using opengl for the filters?
