@wwilson will there be any videos and slides? I can't find any links in the conference webpage :-/ Thanks!

> They can do it (surprisingly well, once you disable the friendliness that prevents it) ... Interesting! :D Do you mind sharing the prompt(s) that you use to do that? Thanks!!

Check this [1] HN post from 10 days ago, the first problem listed, "Dual monitors swapped positions" and the cause ("The problem comes from vendors who flash the same exact firmwar…

Reflect Orbital is developing a constellation of revolutionary satellites to sell sunlight to thousands of solar farms after dark. One of the founders shared a video on Twitter sho…

Just out of curiosity, as I've seen a few comments also mentioning PrinceXML. Is OneDoc an API, wrapper, etc, on top of PrinceXML? Or is it a completely new rendering engine? Thank…

Interesting! Have you considered reaching out to one of those (e.g. Citymapper) and see if they would like to work with you? Either employ you, subcontract you, use you as an API, …

Another nit, the "abandoned" part is the one that was open sourced a loooong time ago. Since then, it underwent a ton of changes but yeah, it's within Facebook. So, not abandoned a…

Just a nit, for Facebook, Scuba is not the logging ingestion service. It's Scribe, which Scuba itself uses as the ingestion :) https://engineering.fb.com/2019/10/07/data-infrastruc…

RAMPANT!!? It's really hard to believe that people still write stuff online without doing some basic searching. But here we are... Here's a couple links to illustrate how RAMPANT k…

Thanks! I just can't wrap my head around the fact that someone is willing to pay $5 a month for a meme app! XD Are the users active? Have you thought / analyzed if they pay and for…

From your comments, you turned from a one-time purchase to subscriptions. Can you share your attrition rate? Also, how many want to pay per-month VS the full year (heavily discount…

Mmmm, not sure if that would be the case / possible with something like "First home for your use, you get tax exemptions, etc. Second house, for you, X amount of taxes. If rented, …

Yup! paper covers / paper bedding, and the expert handling of midwives. Pretty simple and straight-forward! P.S. also enemas were used in the past... but fortunately, interventions…

I'm not following. I understood from your first comment that you think the amount of data is low ("underwhelming") and from your last comment that it's a lot ("that much data"). In…

Mmm it's not only "telemetry data". It's that (e.g. Scuba) and other types of logs, and not only Facebook (e.g. Instagram as well). Basically, everything that needs logging and pos…

The number in the article is 2.5 TB/s, not GB/s :) (disclaimer: I work in Scribe)

Interesting! Just found out about this, and I googled it out. TIBCO acquired Scribe Software, and Scribe Software was running as early as 1998-1999! :D https://web.archive.org/web/…

The version that was open-sourced kept evolving and integrating with other internal systems at Facebook. That's what made it hard to continue open-sourcing it (why the open-sourced…

That's actually not the case, there's access control :) The article just focuses on certain areas of the system and doesn't go into the security and privacy parts, that's all. (I w…

As others have pointed out in another HN discussion (1), Mongodb's reply is definitely questionable, if only by its tone. I already replied to metheus on Twitter (2) in a thread wh…

As others are pointing out here, Mongodb's reply is definitely questionable, if only by its tone. In any case, I was writing this to note that OnGres has replied to Mongo's reply s…

Mmmm maybe I'm missing something, but... what's preventing the rest of the command from being corrupt? Imagine two commands, CM and DM. CM is good and DM is bad. Noise gets in and …

A few things. First, can't you run Linux inside a Solaris Zone? I don't know much about Solaris stuff (although I do like it very much, I grew up mostly with Linux, which you so mu…
