  • An Update to Mathematics in a Blog Post | Irreal
    runs its own MathJax server and automatically arranges for it to be called That s great if you only occasionally use MathJax but the Org folks ask that if you use it a lot or have a large readership that you serve your own copy or use the MathJax CDN This means that my suggested solution of adding HTML HEAD script type text javascript HTML HEAD src http cdn mathjax org mathjax latest MathJax js HTML HEAD script isn t optimal It results in another copy of MathJax being pulled in which may or may not be the same One of the advantages of using the MathJax CDN is that you re guaranteed to get the latest version so unless you have strong reasons to do otherwise you should use the MathJax CDN The proper way to get the CDN version is to add the line HTML MATHJAX align center path http cdn mathjax org mathjax latest MathJax js to your post s source file Alternatively you can edit the org html mathjax options variable to set it once and for all This entry was posted in Blogging and tagged Tech Bookmark the permalink Another 12 Great Programmers Correct Quotation Marks Search for Recent Posts Elisp Summary Emacs for Prose FISA Abandons the Fourth Amendment Again Blogging with Org Mode and Nikola How to Keep Emacs Running Across an X Crash Recent Comments Mike Zamansky on Blogging with Org Mode and Nikola Phil on How to Keep Emacs Running Across an X Crash Sebastian Christ on European Quotation Marks NoonianAtall on A Hyper Key on Any USB Keyboard Kris on An Example of Why Reproducible Research Matters Links Useful Emacs Commands Archives April 2016 March 2016 February 2016 January 2016 December 2015 November 2015 October 2015 September 2015 August 2015

    plugin although even this isn t strictly necessary I m using LaTeX for WordPress but there are several others The MathJax site has instructions for using MathJax with several common blogging platforms or how to add it to your theme file if you d rather do that In my case I installed the plugin and everything just worked 1 To get mathematics you simply mark up your LaTeX with for in line expressions and for displayed expressions For example f a frac 1 2 pi i oint Gamma frac f z z a dz yields the beautiful Cauchy Integral Formula To get the typesetting locally you have to arrange for the MathJax JavaScript to be loaded With Org mode I simply added HTML HEAD script type text javascript HTML HEAD src http cdn mathjax org mathjax latest MathJax js HTML HEAD script near the top of the source file If you re using a different system why for goodness sake you have to arrange to get the script markup into your generated HTML Once you ve done that the mathematics should appear locally when you preview your post Very simple no As I say I m abashed that it took me so long Footnotes 1 If you re using org2blog to publish your Org mode blog posts you need to turn off org2blog s automatic translation of the mathematics markup with setq org2blog wp use wp latex nil This entry was posted in Blogging and tagged Emacs Org mode Bookmark the permalink Shamir s Secret Sharing Implementation Things My Mom Taught Me Rafael I am a mathematician too that uses org mode to put content on the web I would be interested to hear if you have any ideas to export theorems in a nice way For example currently in beamer export there is an option to include theorems in org markup It would be great if they could also be made to export to html and even better if they could be numbered and referenced Thanks for the tip about including mathjax per document In my octopress blogs I define some code to load it for all posts even those that don t include math That is certainly inneficient jcs I haven t needed that so I don t know I just messed around with newtheorem but MathJax didn t recognize it Of course I didn t try very hard so maybe there s a way Try asking on the Org mode list If there s a way someone there will know Marcin Borkowski Yes MathJax is really nice Out of curiosity what did you specialize in in maths jcs Functional Analysis My thesis area was approximately Functional Analysis Banach Spaces Operator Theory xah lee i would love to see your math posts now and then Phil Maybe I ve misunderstood but it sounds like this approach requires readers to have Javascript enabled Surely you want the end result to be inline MathML markup which I m fairly sure

  • Feeling Better | Irreal
    re on the mend I was pondering whether I could introduce you to some nice Emacs feature that you d not previously played with to speed your recovery along by way of a fun distraction Have you ever played with SES the spreadsheet application C h i g ses RET While it s not perfect e g the sole method of importing data is by yanking text which must be lines of tab separated columns it s still extremely capable and of course you can use elisp formulas The next time you need a spreadsheet give it a whirl jcs Thanks Phil I ll give it a whirl I already do all my spreadsheet stuff in Emacs with Org mode tables but SES looks interesting Phil You know I m still an org mode novice and I ve not used SES in a long time I have a hunch that org will turn out to be the nicer option by a large margin for a whole bunch of reasons and you ll probably be underwhelmed by SES But hey options Let s try something completely different The easy way to vary a face depending on the display type you re using so that it looks good in all situations M x customize face and pick something Open the State menu and select For all kinds of displays Now INSert a new display option open its DISPLAY menu and choose specific display Select for example Type and then TTY Select Supports attributes and then Show all attributes Make some changes apply them and now Emacs will use the new settings for that display type Phil Whoops ignore the Supports attributes bit You probably don t need that The attributes list to configure is underneath all of that Search for Recent Posts

  • Using the Keypad | Irreal
    keypad on the regular keyboard that is accessed by the function key Thus kp 2 is accessed by pressing fn k and that s not much harder than say Ctrl k other than for a slightly longer reach for the fn key So there are two takeaways from Lee s post If you have a work flow like Lee s you might find it useful to add a list of keybindings to open frequently accessed files to your emacs or init el file Don t forget about the keypad even if you re on a Mac as a source of keys suitable for binding to frequently used commands This entry was posted in General and tagged Emacs Bookmark the permalink Debating Copyright Without the RSC Get Rid of the TSA Before They Kill Us Magnar Sveen If you re on OS X you can also simply bind fn to say hyper That s what I ve done Voila a new modifier key that s real easy to hit jcs Hi Magnar Thanks for stopping by I love the videos and am absolutely addicted to expand region and multiple cursors I ve thought about mapping fn to hyper but I sometimes want to adjust the volume or start stop music while I m in Emacs so I ve resisted doing it so far Right now I use right command as hyper but that s less convenient than fn so perhaps I ll change Magnar Sveen Cool glad to hear it On my Mac at least I can still use fn to change volume and start stop music It s pretty nifty Magnar Sveen And to be a little more helpful this is how I did it setq ns function modifier hyper jcs Wow Thanks I just assumed either fn would act
