In this video I show how I dehydrate (and then rehydrate!) my sourdough starter, Ozzy. Dehydrated sourdough starter can last for years and years if stored properly (in a cool, dry, dark location such as in a pantry). Took me approximately 3 days to revive the dehydrated starter after several feeds with water and flour. My water is purified tap, and I use a mix of 10% Bob’s Red Mill rye/90% King Arthur bread flour (12.7% protein). I maintain my starter at 100% hydration by feeding with equal amounts flour and water, by weight.
1. Be sure your starter is very active, and then spread out your starter in a thin layer on a sheet of parchment paper (approx. 30g is great). Cover with another sheet of parchment paper. Let the starter sit at room temperature for 24-36 hours until *completely* dried.
2. Once dried, I like to crush the starter between the two sheets of parchment paper and then transfer to a small blender to grind.
3. Grind down about 30 seconds until the starter chips are all finely ground. Transfer to a glass mason jar with a tight lid, and store in a cool, dry, and dark place such as the pantry.
To Rehydrate (see video at the 1 minute mark):
Day 1: Measure out 5g dehydrated starter and add 10g warm, purified water. This is a 1:2 dilution. Stir well for 20 seconds and then cover loosely with a lid. Let sit at room temperature about 30 minutes to rehydrate a bit. After the 30 minute rest, add 10g flour mix and stir very well. Cover loosely and let sit somewhere warm (~80degF) for 24 hours.
Day 2: Add to the jar 10g purified water and 10g flour mix. Stir well, cover loosely, and let sit somewhere warm again for 18-24 hours.
Day 3: In the morning of Day 3, you should be seeing pretty nice activity in your starter if you kept your starter somewhere warm. Discard all but 5g of your starter, and move to a fresh clean jar. Do a 1:2:2 (starter:water:flour) feed – meaning add 10g water and 10g flour mix to your jar. Stir well, loosely cover, let sit ~80degF for 8 hours. In the afternoon of Day 3, discard all but 5g of your starter. Feed again 1:2:2 (add 10g water and 10g flour mix) and stir well. Let sit ~80degF for 6-8 hours. Before bed, feed once again, this time 1:5:5 (discard all but 5g starter, add on top 25g water and 25g flour) and stir well. Let sit ~80degF overnight, approx. 10-12 hours.
Day 4: Your starter should be completely revived at this point! You can now use this activated starter to build your levain and bake bread! I usually require about 60g levain for a bake, so I’d take about 20g activated starter and mix in 20-25g water and 20-25g flour mix. Let sit for 4-6 hours at 80degF and then add to your autolyse!

This site provides links to random videos hosted at YouTube, with the emphasis on random.
The original idea for this site actually stemmed from another idea to provide a way of benchmarking the popularity of a video against the general population of YouTube videos. There are probably sites that do this by now, but there wasn’t when we started out. Anyway, in order to figure out how popular any one video is, you need a pretty large sample of videos to rank it against. The challenge is that the sample needs to be very random in order to properly rank a video and YouTube doesn’t appear to provide a way to obtain large numbers of random video IDs.
Even if you search on YouTube for a random string, the set of results that will be returned will still be based on popularity, so if you’re using this approach to build up your sample, you’re already in trouble. It turns out there is a multitude of ways in which the YouTube search function makes it very difficult to retrieve truly random results.
So how can we provide truly random links to YouTube videos? It turns out that the YouTube programming interface (API) provides additional functions that allow the discovery of videos which, with the right approach, are much more random. Using a number of tricks, combined some subtle manipulation of the space-time fabric, we have managed to create a process that yields something very close to 100% random links to YouTube videos.
YouTube is an American video-sharing website headquartered in San Bruno, California. YouTube allows users to upload, view, rate, share, add to playlists, report, comment on videos, and subscribe to other users. It offers a wide variety of user-generated and corporate media videos. Available content includes video clips, TV show clips, music videos, short and documentary films, audio recordings, movie trailers, live streams, and other content such as video blogging, short original videos, and educational videos. Most content on YouTube is uploaded by individuals, but media corporations including CBS, the BBC, Vevo, and Hulu offer some of their material via YouTube as part of the YouTube partnership program. Unregistered users can only watch videos on the site, while registered users are permitted to upload an unlimited number of videos and add comments to videos. Videos deemed potentially inappropriate are available only to registered users affirming themselves to be at least 18 years old.
YouTube and selected creators earn advertising revenue from Google AdSense, a program which targets ads according to site content and audience. The vast majority of its videos are free to view, but there are exceptions, including subscription-based premium channels, film rentals, as well as YouTube Music and YouTube Premium, subscription services respectively offering premium and ad-free music streaming, and ad-free access to all content, including exclusive content commissioned from notable personalities. As of February 2017, there were more than 400 hours of content uploaded to YouTube each minute, and one billion hours of content being watched on YouTube every day. As of August 2018, the website is ranked as the second-most popular site in the world, according to Alexa Internet, just behind Google. As of May 2019, more than 500 hours of video content are uploaded to YouTube every minute.
YouTube has faced criticism over aspects of its operations, including its handling of copyrighted content contained within uploaded videos, its recommendation algorithms perpetuating videos that promote conspiracy theories and falsehoods, hosting videos ostensibly targeting children but containing violent and/or sexually suggestive content involving popular characters, videos of minors attracting pedophilic activities in their comment sections, and fluctuating policies on the types of content that is eligible to be monetized with advertising.
