Thanks to everybody helping out so far! Martin -- Hello, at least on cygwin libsingular still fails to build. Singular.exe seems to work. In addition it seems that a failure during the singular build screws up python as well as some other components, i.e. import md5 fails. Rebuilding python fixes that, but then pyres has some rather odd problems, spkg-install in the singular build directory then fails due to a missing gmp. The problem with libsingular seems to be that certain symbols cannot be exported. The package also still has a libsingular.dylib copy in it. Can you check with your build whether/how we delete bits? Restarting from scratch is rather expensive on cygwin :( Dang, as the Windows FS is case insensitive make clean actually nuked the complete local/lib subdirectory. That means that I have to start from scratch i.e. as a compile will take at least 10 hours so do not expect results soon :-(.

Hello, First off, nice job with the redesigning of the SAGE site, it's looking good. About the sage logo, it's cool you guys want to display it as the icon for sage, thanks. On the other hand, it's true that look can come off being a little cryptic, but I wanted it to look 'fast' and 'cool' and the 'a' and 'g' come together to form an infinity sign, which just screams 'cool math' ;) I would definitely like to help making it more clear to read, but I not sure yet how to exactly do that ... I kind of like the way the shape of the logo is (btw, it looks a little squished on the homepage), but maybe I could accent the 'a' to make it stand out, or maybe add more of an outline to all the letters to make them all stand out, or maybe just add some text below like: SAGE: Free Open Source Mathematics Software (or some shorter catch-line) in stylized text to make it clear what the logo says above. I'm open to any ideas, thanks, -Alex On 5/6/07, mabshoff [EMAIL PROTECTED] wrote: Hello, To be clear, it's the way the 'a' and 'g' are joined, together with the 'type face', that makes for a complex visual experience (:-}), at least for me.

Perhaps you could have the menus that appear at the top and bottom of the main page appear on each sub-page, as well as the grey borders. It would give the overall site more consistency, and give the user a feeling of still being at the same site. You could add the download, documentation, etc. links to the menus on the sub-pages too. It's good for a user to be able to navigate from any page towards where they're trying to get. The front page is quite nice. As I continue to navigate downward (as a n00b user), I keep seeing comforting familiar things, like Gnu, Python, and Firefox, and I start to think, what is this new, intriguing math software wait it's *free*!? I completely disagree that two columns are confusing. The fundamental flaw of so many annoying websites is an abundance of gimmicks and no real content. Personally, I hate mouseOver effects. One reaction I had was to instead of an obscure language designed for mathematics. ...designed for, maybe a particular mathematics program, or... there's something kind of pejorative about the way the word mathematics fits in there...

Anyways, your comments on the mockup here would be welcome: http://sage.math.washington.edu/home/was/rc/web/index.html (Note that links to actual downloads etc might not work.) My questions are mainly: (1) do the pages look: -- visually appealing -- simple and clean -- convey all the necessary information (i.e., I'm not missing key things that used to be there) I really like new, clean user-targeted design. I might be coming a little late into the discussion, but I did have some additional thoughts. I might add a couple of links to some of the graphics (which wouldn't visually change the page at all). Like to the GNU icon, a link either to something on the gnu website (though often their treatment of the topic is a bit heavy-handed) or preferably to a page containing that quote about the Sylow theorems and a link to browsing the entire source. The python one could link to the python page (for people coming from the mathematics side of things) and the Use most matematics software... could link to a list of interfaces (perhaps this list could be merged in with the components. I'm not sure Be curious could link to a relevant page in the tutorial. I think the text for the download blurb makes it a bit confusing as to what SAGE actually is. Perhaps something along the lines of SAGE is available for Windows, Mac OS X, and Linux. SAGE also makes it very easy to install or build from source most major open source math programs. Download SAGE here. I think the Try SAGE online link(s) need to be much more prominent, perhaps even placed somewhere in that last paragraph. (2) does the text on the front page reasonably convey what SAGE is to somebody who say has never heard of programs like GAP and PARI, and just wants to know if SAGE might be for them? Yes, though perhaps it could do a better job of presenting itself to people who do use these systems. I'm not sure how redundant this would be with the next paragraph, but perhaps something could be added to the second paragraph to the effect that SAGE leverages/ includes existing high-quality open source math packages such as... (3) Does the front page text seem to much like sales talk? Compared to Maple or Mathematica's web pages it's nothing (those pages are gut-wrenchingly obnoxious), but it might still be too much.

I'm slightly concerned about using the GNU logo. To my eyes it suggests that SAGE is part of the GNU project, which it's not. The GNU logo to me says more GNU project than free software. The Python and Firefox logos somehow don't give that impression, I guess because I usually think of GNU as an umbrella project, whereas I think of Python and Firefox as more specific, and I see them all over the place all the time.

Sorry. I definitely should have been more specific. This is on Ubuntu 7.04, x86 32-bit (Core Duo), and it happens for any file (.sage or .py). Specifically, when I tried this example, 'something.sage' was a file containing a single function definition. It also happens if the file is empty.

I'm still getting the same error with alpha3, reproduced again below. This also affects the load command, and the load command now gives other errors if quotes are not used (these are below). All of these commands worked fine with 2.5alpha0, but not 2.5alpha2. The IPython version included in SAGE did change between alpha0 and alpha2, so maybe the problem lies somewhere in that change - although that is just an ignorant guess. Incidentally, there were no problems with [EMAIL PROTECTED]:~/sage2.5/sage-2.5.alpha3$ math test [...] -- All tests passed!

Nick,
I tried these examples in sage-2.5.alpha3 on several platforms
and in all cases they work perfectly. What version of SAGE, what
platform, etc.?

[sage-devel] Re: sage2.5alpha3 attach bug
Hi Jonathan, Thanks for the bug report. I've fixed this for sage-2.5. The problem was due to a switch from the string type to a unicode type in the new version of IPYthon. William On 5/7/07, Jonathan Bober [EMAIL PROTECTED] wrote: I'm still getting the same error with alpha3, reproduced again below. This also affects the load command, and the load command now gives other errors if quotes are not used (these are below). All of these commands worked fine with 2.5alpha0, but not 2.5alpha2. The IPython version included in SAGE did change between alpha0 and alpha2, so maybe the problem lies somewhere in that change - although that is just an ignorant guess. Incidentally, there were no problems with [EMAIL PROTECTED]:~/sage2.5/sage-2.5.alpha3$ math test [...] -- All tests passed!
