Yup, on my list. Probably not soon.

How does it fail? And, can you post the XML?

It causes an error (red halo around the block)

Here is the XML for the whole project: (so far)

[drumroll]
The University of California at Berkeley, the MioSoft Corporation, Jens, and Brian are pleased to announce (at last) the official beta release of Snap! 4.0 with cloud storage!

Jens says that if you want a really short user name you have to figure out how to hack the code. hmm

For the moment we're only announcing it here, to keep the number of users down until we shake out any bugs you intrepid users discover. smile

Aw, no fair, the server gives "ERROR: Username must be 4 characters or longer" sad

EDIT: but yeah, awesome! big_smile Now to get started on that HTML parser...

Some thoughts:
* In the save dialog, could the cloud option be selected by default if you're logged in?
* It'd be awesome if the login dialog re-appeared if there's an error (like mistyping your password).
* If a project's been modified on the cloud since loading it, saving will happily overwrite your changes (!)

How far are we allowed to go while hacking? (I took that as an invitation to hack the system)

You are totally welcome to find bugs in the server, provided you tell us about them! big_smile

Aw, no fair, the server gives "ERROR: Username must be 4 characters or longer"

When I complain to Jens about this useless policy he just laughs. Start a petition on one of those petition sites or something.

PS It's my fault they put a test in the server; I grabbed "bh" first thing. smile

PPS Anyway, I thought you wanted "blob".

I can't have both that and "b"...? tongue

Accounts are indexed by email address, so not from the same address.

Yep, that was my plan. smile
ATM I'm trying to hack widgets.js.

EDIT: Grr... Snap! doesn't like being offline AND connecting to the cloud.

:'(

I did find a bug in the client: it doesn't urlencode some parameters, so if you put an ampersand in your email it blows up.

EDIT: Gaaaaaaaaaaaaah. Why can't you just use browser form fields? I can't use my password hasher.

EDIT2: @. is a valid email address.

EDIT3: "Sign up" is two words (the dialog knows this, but the menu item doesn't).

EDIT4: "callback" is one word. Always. Not "callBack." (just like "idx" is not a valid synonym for "index")

I feel your pain. I never really, really needed copy/paste until now. I guess Jens must use the same password on all his bank accounts. smile

PS "Sign up" is a verb; "signup" is a noun, I believe.

EDIT:

Jeez, n, you're not nearly old enough to be so pedantic!

EDIT 2:

EDIT3: "Sign up" is two words (the dialog knows this, but the menu item doesn't).

It took me a while to work out that the "is" in edit 2 means "is wrongly taken to be" whereas the "is" in edit 3 means "is"! If we're going to pick nits, style problems that actually impair communication trump arbitrary style diktats. tongue

Aren't they both verbs in this case, though (like "Save" (menu item) or "Open Project" (dialog title))?

Don't waste time taking courses with "pre" in their names. Have you done trigonometry? If so, just go straight to Tom Apostol's Calculus book. And then you can read Knuth's discrete math book.

I was talking about trig, logarithms, and complex numbers. I can handle trig and logarithms (well, I hate logarithms and logarithms hate me, but that aside) but I haven't really looked at complex numbers yet.

I basically do everything from AoPS books, because they are really good at covering all you really need to know and then giving tough but manageable problems.

Oh, I agree with you that the menu should say "sign up"; it's just that you were so emphatic about there being no such word as "signup"! smile

AoPS is great, right?

Have you seen Richard Rusczyk's (sp?) videos? They are on youtube and the AoPS website as well. I just watched all of his videos on the 2012 AIME, it was amazing.

Ah, this is new to me. Thanks for the pointer. But why oh why don't they put sample pages on their web site? I can't tell, for example, from what I read there, whether or not they take an axiomatic approach to algebra -- proving, for example, that if x is a factor of y, and y is a factor of z, then x is a factor of z. (Not a difficult theorem; I took it from an early chapter of the algebra 1 book I learned from long ago.)

No complex numbers? Does that mean you haven't run across the sublime Euler's Formula? (The one about complex exponentials, not the one about polyhedra.) I've been thinking you know everything. You have much to look forward to.

What's your problem with logarithms? You don't think it's amazing how they reduce hard multiplication problems into easy addition problems? (You do understand that Napier and those guys didn't have cell phones with calculator apps, right? tongue ) And also how they make it possible to picture enormous ranges of values, such as astronomical distances? Your book isn't actually making you do interpolation in printed log tables, is it?

Thank you; I was proud of that line!
