Cool project. Call me pessimist but all of these workflow/scaffolding/hooks are being absorbed by the model makers like ChatGPT and Anthropic. In fact, my personal setup with Claude Code is somewhat similar to this setup, except I bend it in CLAUDE.MD

I am doing this and it's fun! The only hassles I had are a. setting up DDNS (since I don't have a static IP) and b. getting a certificate from Let's encrypt with only port 443 open (80 is blocked by my ISP). But other than that, it has been great! Hopefully my ISP won't have a problem with that ;)

“Biological objects can have a complexity that cannot be simulated by a digital computer,” Austin says.

I couldn't find more details in the article. Any idea what those details that couldn't be simulated with digital computers (but could be with the simple robots) might be?

Sorry for not being clear, I meant when all 21 million bitcoins are mined. The transaction fee is pretty small compared to the reward from the new coin, right? Also, since many cryptos have addressed the incentive issue. Maybe let's just focus on bitcoin specifically?

The network hash rate is only so high because the ROI is there, but without it, people would still be mining.

Can you expand on that? What would be the incentive for the miners then? What happens when all blocks are mined?

Also for a more comprehensive listing of the quantum software, see the awesome-quantum-software [0] on GiuHub.

Personally I have used Cirq[1] and Qiskit[2] to implement some classic algorithms like Deutsch-Jozsa[3] and Shor's[4] algorithm and I would say the two frameworks are very similar to use for those implementations.

So, it would be interesting to get some insights/opinions from someone who has used multiple frameworks. Is there any clear win/loss of those frameworks?

Summary:

+ Amazon didn't build any quantum devices.[0]

+ AWS provides a software stack called Braket. [0]

+ AWS provides classical simulation or access to quantum computers from D-Wave, IonQ, and Rigetti.[0]

+ Many companies (e.g. IBM, Rigetti) have already provided similar software stack/cloud quantum devices. For a more comprehensive listing, please see [1].

I am using a decent gaming rig, so I don’t think it is the performance issue. I think it might be related to the touchpad. Are you using mouse for scrolling?

What drives me away from Chrome on Windows is the very short freeze you have after you let the page idle for a while and try to scroll again. It was introduced earlier this year, I think.

Side note, the Edge (not the ChromeEdge) has a nice feature where you can set aside all the tabs so that you can view them later with pretty much the same state, much like a tmux server. I couldn’t find similar features in other browser.

Hello CERN 7 years ago

I apologize for the slow loading... I am trying to optimize...

I have several questions about Karpathy's presentation: 1. How to label automatically using fleet learning? An example he gave is detecting cut-ins. However, I am wondering if it could be applied to more general and basic cases, for example, labeling lane marking/vehicles. 2. How do you know if someone is a good driver (which is essential for imitation learning)?

So I work in experimental particle physics and our daily tasks involve using particle collision simulation tools(mg5+pythia+delphes), distribute them on clusters, construct jet images using ROOT and finally experiment with neural networks on those jet images. So as people pointed out, what we do had a lot in common with the industry (where we learn from as well), which explains why many people involved in this kind of research could land a data scientist job. An interesting thing I've noticed is that many phD students in our group (with little CS background) waste lots of time on getting the software running (either locally or on cluster). You guessed it, we are trying to exploit the power of docker to make it easier for researchers to run those simulation tools.
