We wrote a white paper on transaction costs for direct indexing, another neat read from a DS perspective. I was surprised to see just how (and how consistently) much bid-ask spreads change intra-day. frec.com/resources/blog/direβ¦
Frec launched a direct indexing into S&P500 product yesterday, we wrote up a white paper on the approach and on fairly extensive simulation results. It's an interesting read just from a ML/data science perspective: frec.com/resources/blog/frecβ¦
Ceiling fans are really a bad UX. The fan speed should be represented as an IEEE floating point with a pull string for each binary digit.

the youtube recommendation algorithm has learned blackmail, you WILL watch this because I will not stop recommending it until you do

You might think that kids don't learn useful skills in Roblox. But my 9yo getting scammed out of her best pet in Adopt Me actually seems like a pretty good low stakes lesson.

Really cool to have chatGPT as a second option for search queries that don't work in google. The query "how to prevent facebook from generating link previews for my website" returns nothing of value on google (missing "my website" context), but chatGPT just gives the answer.

Do videos even work on this website for anyone else? Enable sound -> video freezes, enable full screen -> video freezes, do nothing -> video is fine, then freezes.

Since this was "fixed" my first 5-10 tweets on my timeline are always a tweet by Elon or a "Elon replied" injection, whether they are new tweets or a 1-2 days ago.
Long day at Twitter HQ with eng team
Two significant problems mostly addressed:
1. Fanout service for Following feed was getting overloaded when I tweeted, resulting in up to 95% of my tweets not getting delivered at all. Following is now pulling from search (aka Earlybird). When Fanout crashed, it would also destroy anyone elseβs tweets in queue.
2. Recommendation algorithm was using absolute block count, rather than percentile block count, causing accounts with many followers to be dumped, even if blocks were only 0.1% of followers. Also, itβs trivial to bot spam accounts with blocks.

which public figures? I'm sure we can expect a straightforward and transparent approach here
Not all previously verified accounts will get the βOfficialβ label and the label is not available for purchase. Accounts that will receive it include government accounts, commercial companies, business partners, major media outlets, publishers and some public figures.

Whenever a driver chooses to wait at an intersection and not run me over on my bike I give them a little wave

there is a lot of talk about war, climate change, and elections but no one is talking about why the "draft" pull request button on Github is not a different color than the regular create button.

my Peloton bike almost electrocuted me after the transformer shorted out from sweat dripping on it, hopefully the bike electronics still work... @onepeloton y'all should really make the transformers water-resistant to some degree.

When I look for things:
Check the obvious place
Check some other place
Check the obvious place again
Check some other place
Check the obvious place, found it!
