This is really cool and promising product! So many times when I was getting a google docs spreadsheet from non-engineering folks I was wondering if only I can embed a small jupyter notebook with a few python cells and a nice looking pandas

Sure, I agree, above certain usage threshold hosted Trino becomes totally justified. But then, some engineering time to maintain the cluster has to be factored in as well.. for anything ad-hoc in nature, I would start with Athena by default

other arguments aside .. Athena costs $5 per 1TB scanned and also supports predicates pushdown to S3 Select. I wouldn't call this expensive, at least in comparison to self hosted Presto.

For this particular example direct initialization i.e. std::string product("not worked"); would be preferred, as you end up using one call to constructor instead of two: default constructor followed by the move assignment. https:

Both are legal statements. The second one is a direct initialization, invoking corresponding constructor. The first one first invokes default constructor and then copy or move assignment depending on rvalueness of the arg.

Good progress overall, especially on the Rust side, I wonder if C++ and Rust would at some point follow the same roadmap when it comes higher-level compute features or rather deviate and develop at their own pace. Special kudos to the Rust

That's correct, but SQLite would require to serialize/deserialize the data sent to Python func (from C to Python and back), while Arrow allows to get a "view" of the same data without making a copy. Which is probably not

Following similar observations I was wondering if one can actually execute SQL queries inside of a Python process with the access to native Python functions and Numpy as UDFs. Thanks to Apache Arrow one can essentially combine DataFrame API

That's one of the core use cases for Vinum - to provide SQL query engine, complementing Pandas in data analysis (thanks to Arrow), yet retain an ability to use native python and numpy funcs as UDFs. Also, it doesn't require input

It's a little bit strange that even though Python was mentioned there's not a hint about the actual problem in question.

It always amazes me how people keep recommending CLRS as an interview preparation material. If you haven't studied Algorithms before it will take months to go through material in this book, leave alone making exercises. It is a serious text

If you happen to be asked such questions it might be a good indication that the type they are looking for is code monkey. Or they are just not good enough to assess engineering skills. In both cases it's a red flag.

It seems you like you still hire based on puzzle as a first filter (based on on your careers page). Just wondering, what is the ratio of people who apply with only a resume vs those who solve the puzzle (I understand you probably can't reve

In addition to the map tiles, OSM has an unbeatable advantage over any proprietery solution - you can take advantage of raw data and do whatever you can think of. For example, you can write your own route finding solution, tweak it whatever
