This is awesome. Does anyone know if there is a library for the amazing optical codes that apple uses in its device transfer? I know they have a custom patent for it so I don't know if its something anyone has tried to recreated...


Do you have link for more info on optical codes?


i beat it by having the phone control the direction the robot would move, like an RC controller :)


Sorry, I'm unfamiliar with PLT what does stand for?


procedure linkage table


Agree, in fact this wonderful book calls this out, stating:

  As DuckDB is an analytics database, it has only minimal support for transactions and parallel write access. You therefore couldn’t use it in applications and APIs that process and store input data arriving arbitrarily. Similarly when multiple concurrent processes read from a writeable database.


You’re maybe right, but does that mean the language should be hostile to those that don’t write well designed code?


I think a lot of programmers would say "yes" to this, enthusiastically.


Yes. In particular you would want badly designed code to stand out.


What was the article from yesterday? I feel like I missed something helpful.



Not saying you’re wrong, but what are you proposing as an alternative? How should comprehensive knowledge be tested? Weekly homework/projects?

P.s. love the user name.


For my Masters degree, most of my courses were absolutely like this. Our assignments were difficult and heavy. There was no expectation that you should complete them without Google or reference material.

In contrast, the "final exams" were either non-existent or extremely easy and account for only 10-20% of the grade, where they existed.

I really liked this approach. Make your assignments very difficult. Alternatively, give difficult 10-15 minute quizzes every other week. IMO, it's a much better way of evaluating students.


Just going off the trick above would t it just be: 23 x 10 - 23 = 230 - 23 = 207...

I guess I’m confused what point you’re making?


I was talking about the grand-parent comment's method:

> You can check you’re right if (a) the first digit of the result is 1 less than the number you started with

The first digit of the result is 2 ... And the number that you started with is also 2, which is not 1 less... I guess I am not smarter then a 5th grader


Wow! You definitely are smarter than me, the gp, at least! You’re right that my claim isn’t right in general. Hell, not even past 10, I can now see!

I’m curious, how did you find that counterexample? I kind of ‘overfitted’ my mental model to the first 10 integers. But as a statistician I’m only in the business of being approximately right...! Nice catch.

23x9=207 starts with 20 which is 3 less than 23... 24x9=216, and 21 is 3 less than 24. 11x9=99 and 9 is 2 less than 11, 12x9=108 and 10 is 2 less than 12. So 0-9 are offset by 1, 10-19 are offset by 2, 20-29 offset by 3, 30-49 offset by 4?


This really is great to see, but it’s clear from their careful wording that the google takedown of the recent widevine l3 repository won’t be reversed:

> And our reinstatement, based on new information that showed the project was not circumventing a technical protection measure (TPM)

Since it is clearly circumventing a “TPM.”


It's kinda pointless to reverse that takedown. You can find it elsewhere, and Google plans to revoke the key in Q1 2021 after increasing/changing the obfuscation on widevinecdm.dll.


Notion tables are WAY more powerful than markdown tables...

You can configure views, filtering, sorting, summary’s, and foreign keys with roll ups....

That’s not something trivial to build, however I’d be pleasantly surprised if obsidian eventually got there.


I wouldn't be surprised if a community plugin is developed for this sort of thing. It seems like the plugins are getting more and more interactive.
