This release is a stabilization of the previous big move.
The latest jEditOQMath is uploaded to the developer preview and the download area.
It includes a brand new QMath which is also compiled for less platform: no ppc anymore (please help if you have one at hand with 10.4 or so), and only generic linuxes. This new QMath is a bit faster and is hopefully a lot more explicit for the error messages, it is the release candidate 1 of QMath.
Please give me feedback if works or doesn’t on your platform!
I just met Copy and Paste Math|MathJax which is very interesting but really:
it shouldn’t stay so!
Copy-and-paste MathML should happen as soon as you invoke the copy command after having selected (part of) the formula.
Hopefully, MathJax will consider implementing that part as well.
In this video, I find the paste phase pathetic: one really needs correct media-designation in the clipboard so that such is only needed when you have special desires. That one is a normal desire.
Quite a few polishes in: - Includes input-editor enhancements; Drag-and-drop of formulæ now works again. - Dutch and French internationalization polishes - Groups should be mapped from Moodle courses.
And a lot more, see Jira issue list towards 1.1.
Revision 36 should come to all authors.
A fascinating discussion has been started by Tim Berners-Lee on the TAG mailing list, here’s the pointer to the archive: http://www.w3.org/mid/AFFAB130-B693-4AC9-91E6-B6834E57B3F5@w3.org
it is based on a blog post by John Gruber, Tynt, the Copy/Paste jerks which is also fascinating as a rebellion.
An introduction video of jEditOQMath used to author ActiveMath content can be seen here:
Revision 11 is posted on ActiveMath-SVN.
It now displays roots in HTML (but fails at nesting of roots). It also attempts at displaying the port number in amStartup on unixes. Finally, the notation elements now also work in MathML.
To update… svn update as in ActiveMath-SVN. Nicer display of roots may need an index rebuild.
I’ve just brought the trunk of ActiveMath, as can be seen on devdemo, on the ActiveMath-SVN-stable. This brings a large amount of fixes and features:
The need is extreeeeemely common: you want a map of some region to be included in the next flyer, in your web page, in your learning material. The map should be of good quality, be realistic, and certainly must contain your own annotations. How can you do?
Until yesterday I only knew the answers such as the Google-Maps-Embeddings: very limited annotations, extremely constrained licenses (no flyer for example), pretty slow, … but now I discovered OpenStreetMap.
I’ve been musing with ImageMagick and found a little snippet to produce drop shadows on the command-line with this amazing open-source library.
Given my file input.png I can obtain a version with drop shadow as target.png by running:
A nifty feature has just emerged on daily activemath builds and jEditOQMath: advanced metadata inheritance. Basically, it allows an author to avoid most of the repetition of metadata by simply putting that metadata in an enclosing element.
Are there any known issues or welcome surprises concerning the compatibility and performance of ActiveMath under Snow Leopard Client and Server?
This is the story of a confusion which grew from each other’s copying a “nice example”: it’s about what is the normal notation for the binomial coefficients in Russian and French.
It starts as a paper we are writing, which copied another paper of mine (at MathUI), itself copying others sources, without precise citations (1, 2, and 3), the most authoritative one being MathML 2: all these sources claim that in Russian, the binomial coefficient (the number of subsets of cardinality k within a set of cardinality n) is written while in French, it’s written .
I have been desperate for quite some time for my pupils to have a simple MUI(Mathematical User Interface) to be able to type Mathematics into Active Maths and into Web Pages, easily, consistently and semantically.
Could you please advise?
I came accross Why PHP should never be taught which is hilarious!
I always had a small mistrust of PHP as being a too easy language but this post is a perfect illustration of how things can go wrong if you have the slightest ignorance about all the details of the environment you are programming for! As a summary it says… equality-test in PHP is not transitive!
I am in love with the rsync command-line tool. It’s a careful tool, a brilliant implementation, and well-thought command-line interface that surpasses cp, scp, and many others.
This is a very nice experience I am having: I am editing writing an article in LaTeX and that is with OmniOutliner, the incredibly nice outliner of the Omni Group. Luxury is there to manage the texts, to hide parts temporarily, to apply styles and to navigate while the quality of the LaTeX output remains.
Recently I encountered two websites which are really for educational purposes, even for math education purposes, two educational entreprises that aim at making mathematical content web-accessible. But it really is only “user-browser-web-accessible”… two examples of the wrong approach of rich internet applications.
David Carlisle informed us today that:
chapter 6 is now chapter 7…
(indicating that we now have reorganized the chapter 6 of MathML specification to become the chapter 7 and vice-versa).
This had the topic “end of an era”.
Not at all. Funny it is but the fact that it needs a mail with such an emphasis proves the care taken to develop the MathML standard at W3C: the wish of ongoing compatibility goes as far as chapter numbers. And indeed, it really means that people speaking of chapter 6 will have to change their words.
An Agency is an entity who is capable of doing some act. Or some one who acts on the behalf of some other one. In software Agents the code is not executed on demand but runs continuously and decides for itself when it should perform some activity. They are capable enough to deside and select their tasks by their own, only the thing is they need some triggers to start their work. They can prioritise their tasks. They have most of the time a goal to achive. So their activities are directed to some goal. They can make decisions with out human intervention.
The Semantic Web is not Restricted to Ontologies!
The semantic web is a nice strand. Something where AI should be able to do a huge job based on the massive knowledge spread around the web. Is it about AI or more generally machine processabiity? The last call for paper for the WWW conference actually broadened the semantic web track call to “Semantic / Data Web”.
I have created a collection “Essai”, and I would like to create a book “discover” with items of this collection (theorems, examples, exercises…). However, it is not possible: the answer is always “no items available” “go to users data to change your profile” (or something like that). Something must missing in the oqmath/omdoc files, but I do not know what… Many thanks for an answer!
Over and over the discussion of JSON vs XML (vs YAML…) appears: they are compared as languages to serialize object graphs. I may be old fashioned but I find there’s no valid reason for anything but XML.
Here’s a set claims in favor of JSON (or YAML it seems):
Translation tools are many… but what good are they? To my surprise, there’s always some folks that find a tool that sounds cute but then it never helps. Let me try to identify the hard questions of translations’ management:
The fancy conclusion? No tool I’ve met really helps any except the management of duties and generally they do so by making completely impossible the others.
By chance, I noted that my daughter Pénélope’s math-book had exercises for geometry “with software”. So I gave it a try with her: she manipulates the mouse and tries… I just guide. It worked real well!
You know what?
A content-dictionary as can be found by tons on http://www.openmath.org/cd/ is mostly a social artifact. It’s a set of descriptions of symbols so that one can mean what others means.
