“School comes first”? What kind of priorities does this person have?

There's a whole vast Scratch community out there that I know nothing about. Sad.

Are you active on the snap foruns as well?

he's literally a manager of the snap project.

Annoyingly, my signature was eaten by a small, white dog. How annoying.

It is clear to me that Snap! is much more than Scratch 3, because of the important additions that make it a more general and useful programming language. But has anyone had a sense of which is faster (and, roughly, how much) among Scratch 3 and Snap, when they run the same projects?

Thanks in advance for any opinion (or fact).

I've noticed an extremely large speed improvement in Snap!. Also, for some reason if you don't use the repeat block it runs atomically.

What do you mean? Could you provide an example?

Done with Scratch but want a little more? Try GP…

Repeat, repeat until, or forever – any of the looping blocks. Also the slow blocks, such as glide, and a recursive call in a command block.

This is true in Scratch, too; a thread yields every time it reaches the bottom of a loop. The idea is to keep threads synchronized even if one is a little slower than the other. So if you have a script FOREVER [a bunch of Move blocks–not glide] and another one that does FOREVER [turn], you get a regular polygon, not a random walk.

Jens has been working hard at optimizing Snap!. For many projects it's as fast as writing the code in Javascript, in a big JSFunction block.

Snap! Conference 2019 // Heidelberg, September 22 - 25, 2019

https://snapcon.org

Alas, we don't have funding for travel scholarships, but we do have a super-cheap €10 conference fee for kids. And on-campus housing that's said to be going to be cheap, although they haven't posted details yet.

Lots of opportunity to sign up to do 5-minute talks, as well as longer ones.

Really I just want to meet you all. :-) The events are secondary. At least some of you live closer to Heidelberg than to Berkeley, although I guess if you live in NZ it's a little further away, sorry.

Yeah it's great living on the other side of the world and 12 hours ahead of everyone else.

I wonder if the right strategy is to apply for https://www.heidelberg-laureate-forum.org and go to snapcon iff HLF pays for travel… the dates literally coincide!

Now there's an idea–we could try to get Vint Cerf to take time out to keynote SnapCon.

Snap! cloud brief downtime:

The cloud will be unavailable for a short time midnight California time Easter Sunday morning (three days from now).

We have outgrown the virtual disk on the server and have to be offline while upgrading it. This is a routine operation, and we expect no problem with it. Sorry for the inconvenience and for the short notice.

Why can't snap.berkeley.edu point to the same IP as bjc.edc.org when not working normally?

The website and Snap! will still work just fine. Loading projects from the cloud, logging in, etc. will show a “down for maintenance” message.

Eventually, we won't need to take the cloud offline for these tasks, but that's a larger project.

bug report: the first dropdown of

([whatever v] of [Sprite whichever v])

is completely blank, both in the dev build and the current build.

You probably should use github foe that.
