I haven’t used the columnstore in production and can’t vouch for it either. It makes sense that k-ordered write performance on column-oriented data would suffer, do you know of a good benchmark measuring this? Also I don’t like the phrase “

How long does your integration test suite take to run? I have (many) typed interfaces and an editor running the language server. Typos, bad imports, etc are highlighted instantly and inline so they get fixed right away. Even better, autoc

Recently some colleagues started using the type annotations in the latest python3. Really excited for this feature! It’s going to make a lot of our production systems safer to work with. And of course Rust is a great technology, etc.

But this claim is simply wrong in a large percentage of cases (at least among the “web application” projects I have seen firsthand).

Yes, probably! The hard thing about that approach might be handling conflicting signals and determining a "source of truth" in adverse situations. Generally speaking, there are variables in the real world that will trip up any giv

No part of our system uses amplitude data, not even on the local device. We only rely on phase offset/depth data. However you're correct that simply choosing a particular technology cannot automatically "solve" privacy,

Unfortunately, as far as I know LIDAR is still prohibitively expensive for this. Someone did invent a solid-state LIDAR system recently, which seems like a good sign.

I work on the software side, so I can't really comment with authority, but this looks like it could be an interesting lower-frequency/lower-power approach to active sensing. From the preview site, it seems like the "resolutio

Yes, we have active R&D projects focused on addressing this kind of drift. In smaller rooms where the environment is favorable, we will usually see the device count for a whole day without any mistakes. But in general there are diminish

by guscost 8y ago
That is the other side of our approach, yes. Active depth sensing and on-device deep learning means non-trivial power and speed requirements, so the hardware isn't as cheap as we'd like it to be. I'm not up to date with the l

Thanks for these notes. I’m suspicious of unconditional praise for any technology, and a lot of the goodwill for Elixir seems like it’s biased by the intention to promote adoption of the language, or like it’s from people who haven’t encoun

The fancy tools can check your code as you write it and highlight problems inline so you don't have to switch context in order to fix them. This saves time in any language, but static analysis with Rust is unusually powerful so tight
