spacecowboy @spacecowboy17.bsky.social · 13/09/2026Last week I ran an A/B test in For You where the treatment arm had a higher penalty for popular items and items with more paths leading to them were boosted more. Statistically significant results: 0.6% more users liked at least something on a given day 4.7% more likes per user 11165
spacecowboy @spacecowboy17.bsky.social · 12/09/2026I'm not nitpicking on @gruber.foo but clearly atproto needs more evangelizing, education, marketing if tech people like Gruber don't get things like this right: - uses "username@bsky.app" instead of "username.bsky.social" - refers to the domain name as the identity instead of just being a handle... 3431
spacecowboy @spacecowboy17.bsky.social · 06/09/2026PSA: you can find out which of your likes caused For You to show any given post at foryou.club/explain Just enter the post URL and hit "Explain": 931146
spacecowboy @spacecowboy17.bsky.social · 05/09/2026For the last 6 months this drive was used exclusively for serving the For You feed Some stats: - 28% of wear - good thing I've set up daily backup to hdd - ~600TB written - 472TB read - weird that it is less than writes 3610
spacecowboy @spacecowboy17.bsky.social · 05/09/2026Random fact: the number of people who enabled hideFromAlgorithmicRecommendations is 7967 4312
spacecowboy @spacecowboy17.bsky.social · 03/09/2026Hmm, spelling it out actually makes it easy to test out the opposite - what if Bluesky was 2x smaller, how much worse would For You become? To do that I just need to make For You only pay attention to the posts authored by users and liked by users with even hash values of the DID. Thanos style. 2751
spacecowboy @spacecowboy17.bsky.social · 30/08/2026I'm setting up backup for the For You database and I'm trying to do a restore from the backup on the hard-drive to the nvme. This eats up all disk IO and makes the feed super slow. I should get it back up in 20 minutes. 3156127
spacecowboy @spacecowboy17.bsky.social · 29/08/2026For You users are liking 1 million posts a day - crazy! There are ~20M likes per day, which makes For You account for 5% of it. 437327
spacecowboy @spacecowboy17.bsky.social · 25/08/2026A common misconception about Bluesky is that it "has no algorithm". In fact it has many algorithms - custom feeds. You can choose which one to use. What does it look like? You can replace the built-in fyp called Discover with a custom For You that runs on my gaming pc in 23 seconds: 519341
spacecowboy @spacecowboy17.bsky.social · 23/08/2026What do custom feeds like For You look like for permissioned spaces? 1241
spacecowboy @spacecowboy17.bsky.social · 22/08/2026I finally looked into why the For You sqlite db file has been growing to be quite large - 589GB. To prevent the unlimited growth I regularly delete likes older than 90 days. The size of the "ratings" table should be stable (there are ~20M likeds per day). Turns out another source of growth is... 71865

spacecowboy @spacecowboy17.bsky.social · 22/08/2026Ahh, For You is returning errors because Bluesky added another ip address from which to make requests (38.142.8.130) and I need to give it a higher QPS limit in nginx. I wonder why nobody mentioned this yet... 2370
spacecowboy @spacecowboy17.bsky.social · 19/08/2026I showed this survey post to For You users over the last 9 days. 1099 people submitted their response. Thanks everyone who participated and replied to the post with more details! I will spend some time analyzing the numbers and will publish the results on blog.foryou.club 3481
spacecowboy @spacecowboy17.bsky.social · 16/08/2026It looks like we are back for real this time. Curious to read the postmortem. Here is the shape of the outage from the perspective of the For You feed. There were a couple of recovery spikes. Jetstream was also down and recovered a bit after the app started working again. 1364
spacecowboy @spacecowboy17.bsky.social · 16/08/2026It looks like the outage is slowly recovering? 5330
Reposted by spacecowboyspacecowboy @spacecowboy17.bsky.social · 16/08/2026I'm thinking of how For You could help the cold-start problem for new posters here. If nobody has liked your posts yet then you would not show up on For You. I think there could be a mechanism that helps people get discovered by the right audience and that is resilient to gaming/abuse. Ideas? 1152

spacecowboy @spacecowboy17.bsky.social · 13/08/2026For You but cross-lexicon: find people who liked the same Bluesky posts as you and show you what they: - liked on standard.site - starred on tangled - rsvp'ed on atmo.rsvp - saved on semble.so - listened to on teal.fm - etc 817513
Reposted by spacecowboyspacecowboy @spacecowboy17.bsky.social · 09/08/2026Thanks everyone for the ideas! I'll go with "🔋Turbo" This mode will be part of user research - I will run a survey among For You users on how much they would value a For You feed that works extra hard. Please help me beta-test the survey: foryou.club/turbo 1304
spacecowboy @spacecowboy17.bsky.social · 09/08/2026Suppose there is a version or a mode of For You that works twice as hard to find good posts. 1. What would you name it? 2. What emoji would go well with it? 34891
spacecowboy @spacecowboy17.bsky.social · 08/08/2026I want to do some user research. Is a "cup of coffee" the most universal measure of value? Or is there anything better? 3200

spacecowboy @spacecowboy17.bsky.social · 30/06/2026Custom feeds can mark some posts as pinned. For You uses it for system messages like "Welcome to the feed" and such.

spacecowboy @spacecowboy17.bsky.social · 28/06/2026For You will be down for ~20-60 minutes - I will be upgrading my computer's ram from 96GB to 192GB.

spacecowboy @spacecowboy17.bsky.social · 10/06/2026How about this - you create a For You "peek" link which other people can use to temporarily turn their For You into your For You. They get to see how you curated your feed. 6940
