@jeff_weinstein I know that guy

good memories of Caffe Centro, some of my first SF nerd meetings there (later hired Andy and worked together for many years.)

@matt8wilson @LemmaFinance same, gonna give @LemmaFinance a try

@RaffiMagarik Just a Twitter thread, but hopefully this makes you feel better.

@jeff_weinstein @ryandawidjan Not teaching SQL right now, but happy to share our curriculum and some tips!

@el33th4xor Just wait until someone comes up with a blockchain based on power law (or worse, Cantor) distributions. The progress bar moves *backwards* until you find a block.

@Sass_toshi @PeterRizun @ProfFaustus From my post: "It doesn’t matter what times you pick - 10 minutes since the last block was mined, totally random, every hour on the hour, your friends’ birthdays, whatever! The expected time until the next block will always be 10 minutes."

@agrano In the bet between @PeterRizun and @ProfFaustus, the t=0 was not a random point in time. What if you ran numbers for this data set: All block time stamps plus 5 minutes in cases where the next block has not yet been found. I suggest you try it.

@7heAbolitionist @PeterRizun awesome, let me know what you find and if you have any questions

Memoryless processes (like Bitcoin mining) are difficult to conceptualize. The fact that a miner gets no closer to a solution regardless of how long he's been mining is counter intuitive. It _feels_ like a block should be 5 min away if we've already been waiting 5 min.

Nice writeup on exponential distributions. To the uninitiated, they will seem bizarre: Bitcoin blocks arrive every 10 minutes on average, yet if it has been 10 minutes since the last block, expected time to next block is still 10 minutes. andygranowitz.com/2018/04/12/emp…

@7heAbolitionist Empirically true: andygranowitz.com/2018/04/12/emp…

@PeterRizun @7heAbolitionist thanks for sharing! glad my post helps explain this :)

@zt @box Thanks Zack :)

Big day at @box! We're launching an Insights Dashboard for admins to understand their company's content, collaboration, and security: box.com/security/it-ad…

@allenday Bitcoin in BigQuery is 👌, but there are some blocks missing from the dataset! Thoughts? cc @felipehoffa Example of missing block: blockchain.info/block-index/16…

@jeff_weinstein only works if your name is also Jeff

@joeyDosik can you share the complete setup used in your #keyscape video? (keyboard, amp, computer, etc) cc @Spectrasonics

@ericxtang @earlofmuir @jeff_weinstein @WagonHQ I'm available to teach our 🧀 themed SQL class anytime! Just say the word :-) And yes, writing well is way harder than SQL.

@tepferdan npr.org/2017/07/24/538… is super cool! Do you have any code for a MIDI controller? Would love to play around on my keyboard 🎹

@rklau thanks for explaining OKRs to @BoxHQ and good to see you!

@mcgd great feeling for the student too!
