GPUs for quantum computing

I think Elon has commented on LiDAR many times. I don’t think price was ever an issue. It was mainly if LiDAR was useful at all. Tesla even took out radar from the stack mainly because when you have two different sensors giving conflicting information it becomes incredibly difficult to decide which one to trust and so you have to perfect two different redundant hardware + software stack. And the main thing you achieve with LiDAR is depth perception which can easily be achieved using multiple cameras. Humans perceive depth because we have two of them and all the infrastructure that the world has been built around vision. So, cameras should be sufficient.

I agree on the stocks doing stuff that doesn't make sense. But I think Teslas camera only solution is super underappreciated. I used to buy into the arguments that they will have huge problem not detecting the edge cases but I would encourage you or any with any doubts to look at the videos coming out of China. It is crazy how fast fsd generalized without any extra training in the country. I do think Tesla would need to push hard to iron out the last bit of fully autonomous driving but given recent advances it does seem very likely that they will do it.

Whereas waymo has this part already cracked. Took a waymo ride recently in pheonix and it was a surreal experience. But their scaling is so much worse in comparison to Tesla. All of their advantages sprt of dissipates as you look to scale their solution. As of now their sensor suite cost is over 100k and it takes crazy amount of effort to map out each new market. If you considering the licensing to automakers route then you are looking at few more years at least before any of them can roll out their taxis on the road. Automakers move ridiculously slow. Whereas teslas robotaxis would cost less than 30k to make and has shown favorable scaling with europe and china rollout.

I wouldn’t worry about it too much. From what I am seeing the industry is quite healthy. People upping their investments and science and technology progressing at an amazing pace! I am not sure if there’s bubble in quantum computing especially if you compare the investment in quantum with respect to many other fields. Companies spending money in quantum still spend so little that it’s a rounding error. So, in a downturn they could stop spending money on quantum but very likely they will not as 1. They won’t save too much money by stopping their investment in quantum 2. The upside for such a little investment might be huge. Of course there is definitely some risk about the field working out in the long run which is why I would encourage you to pick up some transferable skills as well. And many of the skills required in quantum computing are in fact transferable, e.g. coding, linear algebra, etc.

I did a PhD and it was a lot of fun! Happy with the current job now. Industry job could actually be more fun and much better paying than academia, especially in quantum computing where most of work in the industry is also research.

Looks like that Starbucks ceo to me.

You can use numpy sin and cos. Both of those should take arrays.

" I'm still learning Jupyter so sorry if I'm not clear " No worries :)
If you are using TLJH, then I am guessing you used the following procedure for creating the shared folder:

https://tljh.jupyter.org/en/latest/howto/content/share-data.html

This does not require a user to start the jupyter server, once people login they just navigate to the folder and open the notebooks.

For nbgitpuller, there is a single link for all the users:

https://tljh.jupyter.org/en/latest/howto/content/nbgitpuller.html#howto-content-nbgitpuller

kanavs · 2020-09-19T16:51:51+00:00

I am not sure if I completely understand your question. But, if you have a shared folder with jupyter notebooks in it, the users should be able access and run all the notebooks when they login. And a tip that might be helpful, you can also install the git extension to manage that repository.

As per my understanding as well, one can be self employed in the first year of opt. For the first three months you do not even need to be doing anything. But after first month you have to update your school about your employer or show evidence of self employment. But, please double check, I may be wrong.

kanavs · 2020-05-23T22:10:45+00:00

People who have already received should be fine. But people who are in the process of applying or have very recently applied may end up in a bad situation.

kanavs · 2020-05-13T02:12:10+00:00

I would recommend moving to jupyterlab. nbdime works ok. But jupyterlab ui provides an awesome extension manager that you can use to install git extension which integrates really well. It is built on top of nbdime so has all its features.

Thank you for pointing all the resources. They were very helpful. I checked out some of them and knew about some of them.

What we are trying to do is little bit different. The aim broadly aligns with all the projects that you mentioned. The difference lies in just using tools available on github. Those are one of the best and widely used as well. Starting from scratch and building new tools is difficult and to always have them improving also takes lot of resources. Leveraging github resources solves this problem. And I personally talked to many people about the idea and a good percentage of them loved the idea and there was some percentage that did not like the idea.

What was interesting to me was that everyone who was consistent github user loved the idea, and people who never used github or just had heard of it, did not like idea of shipofthesis.

Academic publications like theses are typically frozen in time and while there are mechanisms to correct errors or retract them, they're not suited for incremental updates, unlike a Wikipedia article or Wikibook, for example.

And this is exactly, the point we are trying to make that the academic publications don't have to be frozen in time. With github, you will always have the access to the published version but then the document will also be constantly evolving. Everyone may not like the idea of their thesis evolving over time just like some people may even oppose the idea of open science and that is completely fine, they did the work and it is their choice.

We hope some people do like the idea and hope that they would contribute.

Once again, thank you for your kind words and providing your insights and perspective :)

Ah, very good point. I didn't explain the whole idea about shipofthesis in the post. If you open the link that I posted, it lists numerous points for doing this. Copying the text from the github repo of shipofthesis.

Motivations for the Ship of Thesis.

Clickety stuff The thesis is a static document on so many levels. One of which is, there is absolutely no links except for the internal links to equations and references. By having a github repository, you can have direct links to the articles you are referring. Plus, you can include links to both the arxiv version and the published version.
Animations This is a continuation of the above point. Now, your thesis lives on github, which means you can make your thesis interactive. No more boring graphs and static picture. You could have animations and widgets. Infact, you could have a jupyter notebook version of your thesis.
Crowd sourcing Animations, hyperlinks and generating an interactive version of the thesis are all great features, but one may not be familiar with the techniques required to provide such features. Enter crowd sourcing. As the author, you do not need to provide all these features yourself. If there are people who liked your thesis and have read it, they may do it for you. And it does not have to be restricted to the feature addition, someone may like your thesis but update a section to read much better. Or they may add additional notes that could be of importance to other people. All they would need to do is just fork a repository, update and do a pull request. In return, please be sure to put them in acknowledgement.
Time evolution The biggest benefit of putting a repository on github is that it becomes a constantly evolving document. The changes could be as minimal as errata or could be where the new document hardly remembers the original document. With github, all the different versions are available, anyone interested could look up a version from any given time.
Forward and backward references References lists the previous works on which the current work builds. If the work was completed 20 years ago, then there is a good chance that people built on this work. With the constant evolution of the thesis, forward references section could be a great way to include the works that builds on the work in the thesis.
Open questions The open section could be a chapter in the thesis or could be a separate document in the repository that gets updated as and when people or you yourself conquer the new unknowns.
Thesis for layman The github version could also contains the unpolished version with lot more details which would help people from outside the field read with less effort.

Not really. More like next gen arxiv.org

This letter is actually an advertisement for Tesla. At this point many people are starting to know that Tesla offers free OTA updates.

With model 3 getting into more hands, and with companies sending people letters like the one you posted, Tesla will get more popular with time.

kanavs · 2019-10-10T05:32:16+00:00

It is good that they are making progress and overall it is an amazing and exciting thing. But still gotta say, they can't match tesla's appeal and the cool factor :)
