Just for you I will switch my FTP server to run on Port 23.

Most tech startups will be Delaware. And a lot comes down to the definition of "own" which is ambiguous especially as a C-Corp. One may not be CEO, but can be a H1B Co-founder with a non-trivial (for some amount of non-trivial) number of shares. The O-1 far as I can tell allows for startups, and there may be other visa types which I am unaware of.

Really, I am just saying that the statement "you need a GC to own a business" is far too broad a claim to be true.

There is no obligation to provide the public with his life story. Even if provided, few really understand the US immigration process to really comprehend what it means. And finally, does it matter? Even if deportation is fully legally and ethically justified, do the ends justify the means?

Whether he did really have valid work permits, or not, I have no idea. You seem knowledgeable. But I am just generally mildly frustrated by people online jumping to conclusions assuming malice or criminal intent, while knowing nothing about the US immigration process. It is not surprising that people don't know how US immigration works. Why would one need to unless it is something you have to work with? There are so many misunderstands about H1B, GC, etc.

I do agree that really that the core issue is not with this one particular case, but broadly a pattern of how people are treated, and a failure of due process. People make mistakes. Governments are made up of people who also make mistakes. Process is how you catch mistakes and minimize its occurrence. A failure of due process reduces trust that even fully legal aboveboard immigrants will be treated reasonably and fairly. And that is reducing my confidence that I will be staying in this country long term.

This is not true. You do not need to be a US resident to register a company, and anyone own shares in a company. There are a variety of visa options, and ways to navigate the process that will work.

Its not so complicated. Not everyone wants a green card. It triggers international taxation, exit taxes if you give it up, etc. If you can maintain a work permit for 20 years, why not? Until life circumstances change sufficiently that it makes sense to have a green card, the balance of pros and cons may not lean towards it.

The application, method and algorithm needs to be separated. The application is movie recommendation. One of the methods which works pretty well for this is low rank matrix completion. There are several algorithms for this method, one of which is quantum.

The actual problem that is being solved here is well defined mathematically and is matrix completion via low rank matrix factorization. And using a sampling approach for it. (I have not read the paper in its entirety, just skimmed the intro a bit). It is called "recommendation system" largely due to some history around some of its common appplications (Netflix challenge). But this is not addressing the subjective recommendation problem, but a very particular instantiation of it.

This is using statistics to tell a preconceived story. Underlying this a notion that foreign workers are simply “imported” like they are dug out of the ground or something. How do these STEM OPT people find jobs? Guess what. They interview like everyone else does.

1: Every big tech interview I have been in the visa status is not even a question in the interview process. There is just a simple gate that “can you legally work in the US”? The hiring committee is not even thinking about visa (that’s a HR problem)

2: Are there confounders in that foreign workers are less likely to negotiate? Absolutely.

3: are there confounders in that people who come to US for study are likely already a self selected bunch who are striving to succeed? What are the typical grade distributions between foreign STEM students and US STEM students? Is grade a confounding variable? What happens if we control for GPA?

And finally does H1B abuse happen? Absolutely.

There is a lot of nuance that are not captured by surface level statistics. But nuance does not make outrage.

I think both are necessary. The cdc technique is file format independent. The row group method makes Parquet robust to it.

We are here to help lower that :-) . As we can push dedupe to the edge we can save on bandwidth as well. And hopefully make everyone upload and download faster.

Great question! Rsync also uses a rolling hash/content defined chunking approach to deduplicate and reduce communication. So it will behave very similarly.

I believe Parquet predates Arrow. That's probably why.

Can you elaborate? As I understand Delta Lake provides transactions on top of existing data and effectively stores "diffs" because it knows what the transaction did. But when you have regular snapshots, its much harder to figure out the effective diff and that is where deduplication comes in. (Quite like how git actually stores snapshots of every file version, but very aggressively compressed).
