How long is it likely to be before somebody does this? Hours? Minutes? Angel (talk) 23:56, 27 April 2020 (UTC)

I'd do it myself right now if I still used Facebook... and if I knew where to find it... 173.245.54.115 01:20, 28 April 2020 (UTC)
I did. ¯\_(ツ)_/¯. In vivo veritas (talk) 01:54, 28 April 2020 (UTC)
Although, I wouldn't be surprised if someone's beaten me to the punch. In vivo veritas (talk) 03:32, 28 April 2020 (UTC)
I would be very surprised if someone didn't already posted it days before this XKCD was drawn. -- Hkmaly (talk) 22:06, 28 April 2020 (UTC)

I find it pretty funny that while you can't tweet it, per a recent twitter discovery, you could set that genome as your official gender on twitter (proof of character limit, as an example: https://twitter.com/FaxonFury/status/1254775943664504832). 172.69.22.110 09:03, 28 April 2020 (UTC)

In fact, someone already tweeted it three weeks ago, but they cheated by encoding it into base-64. Here it is on threadreaderapp. Arcorann (talk) 11:00, 28 April 2020 (UTC)

Timgor also made a series of tweets, not just one. Cueball gave up on Twitter too easily. --NotaBene (talk) 12:02, 28 April 2020 (UTC)
I'm wondering what an LZW-type compression scheme could do to sequences, especially with the propensity for repeating sequences (at least outside viruses). And with a known short alphabet you could pre-tune it to work with just four "literal" items and free up a lot more (starting shorter) "dictionary" slots right from the get-go. Not gonna reduce to single-Tweet lengths, even if you could transmit your encoded prompts all across the unicode character sets rather than in 7ish-bit or nearly-8-bit data only. 162.158.158.211 12:22, 28 April 2020 (UTC)

Is the wednesday comic missing? It should be Thursday now in Randalls time zone as well...--Lupo (talk) 05:20, 30 April 2020 (UTC)

Haven't seen it either, it is almost Thursday in PDT. 172.69.34.132 06:38, 30 April 2020 (UTC)
Seems he have missed a release. Although it it still Wednesday for three more hours in Hawaii and a few more hours near the date line... --Kynde (talk) 06:59, 30 April 2020 (UTC)
