I've added 7 videos to my Burrows-Wheeler indexing playlist (www.youtube.com/playlist?lis...), rounding out the r-index series and adding a 5-part series on the move structure. Now 27 videos in that playlist. I aim to add videos on prefix-free parsing, PBWT, Wheeler languages/automata in the future.

Yes, I use the built-in camera on my MacBook Pro, which I've been happy with. It doesn't temporarily lose focus, like I feel like I often see in other YT videos. Lighting is important, at least according to my taste! Which is why I record in a room with lots of windows for outside light.

Please share with anyone who cares about NSF support for graduate students and take 30 seconds to sign and leave a comment.

The deadline for the 2025 Graduate Research Fellowship Program is about one month away and literally no one can apply. #NSFGRFP

The next 48 hours may be a critical time to get attention and awareness on this before the next crisis lets this fade into the background. Everyone holding similar #NSFGRFP writing workshops takes time to sign this letter and reach out to officials.

Thanks for organizing this! It has been incredibly frustrating to see these delays. We spent 5 weeks running a workshop for our incoming graduate students on writing a GRFP fellowship, and now we're wondering if they'll even be able to submit anything.

Donald Trump is way less popular than he wants you to believe.

And you are significantly more powerful than he wants you to think.

That’s me in the video. And a Fox News host just celebrated me being assaulted by ICE.

If ICE will do this to a congressional candidate with a big platform, just imagine what they’re doing to the people they’re kidnapping.

A huge shoutout to all the dedicated grants management specialists at the NIH who are working around the clock to push grants out before the Sep 30 deadline. And also to the POs responding to frantic emails.
Not an easy job under the best of circumstances and right now it's the pits.
Thank you!

More youtube videos coming soon to www.youtube.com/BenLangmead! New recording setup. I've got a couple videos in the editing phase and hope to keep up a rhythm of 1 new video per week.

Who am I to argue?

Trivia: @stevensalzberg.bsky.social suggested the name based on it having "B" "W" & "T" in it. I thought "nah, I'll find a better name" and searched the Linux dictionary file for another "BWT" word. Best I could find was "browbeat". (Runner up: "bewitch"). So "bowtie" won.

The President of the United States is threatening to go to war with an American city.

This is not a joke. This is not normal.

Donald Trump isn't a strongman, he's a scared man. Illinois won’t be intimidated by a wannabe dictator.

This is an actual exchange from a VP who took an oath to defend the constitution and, as a citizen, is expected to abide by the law.

May we one day have accountability for the grotesque lawlessness of this regime.

9 CDC Directors going back to 1977 speak out. What RFK Jr has done to our nation’s public health system "should alarm every American."

This should be the lead story in all major national news outlets. Public health people prefer to stay out of the limelight unless there is no other choice. I can’t overstate how bad things have to be for 9 former CDC directors to band together and pen an op-ed in the NYT warning the entire country.
