Outbound link manager plugin is incompatible with QuickLatex

I found the rea­son for why some­times all Latex in my posts got clob­bered. The cul­prit was an out­dat­ed plu­g­in, which—as a side effect—deleted back­slash­es from posts. So I dein­stalled the sin­ner and also repaired all math that I found was bro­ken. If you still find bro­ken math, drop me a line.


The ‘mod­ern’ look­ing sans-serif font I use recent­ly in \text{\LaTeX} equa­tions on this blog is called ‘Com­put­er Mod­ern Bright’, and actu­al­ly is not so mod­ern at all: Designed by Wal­ter Schmidt in 1996, it is still to date the only free sans-serif font avail­able for \text{\LaTeX} with full math sup­port. Type‑1 ver­sions of this font are avail­able in the cm-super pack­age, but I did­n’t need to install any­thing, because appar­ent­ly, the Quick­La­TeX Word­Press plu­g­in has them already. The only thing to do was adding just one line to the preamble:

\usepackage{cmbright}   % computer modern bright

I also turned on the SVG images fea­ture that was added with ver­sion 3.8 of Quick­La­tex, so the equa­tions are no longer pixel­lat­ed on reti­na dis­plays or when zoom­ing in! Neat, huh?

Various Mac tricks

This is my per­son­al col­lec­tion of com­mand line tricks on Mac OS X that I found indis­pens­able. The list is far from com­plete, and may be added to in the future.

Show hidden files in Finder

> defaults write com.apple.finder AppleShowAllFiles true
> killall Finder

The first line sets the pref­er­ence for the Find­er to show hid­den files, while the sec­ond line restarts the Find­er so the set­ting comes in effect. As an alter­na­tive for the last line, select the Find­er in the Cmd-Alt-Escape pop­up and select “Relaunch”. I found this one on the Mozil­la knowl­edge base [2].

Delete all .DS_Store files

> sudo find / -name ".DS_Store" -print -delete

If hid­den files are enabled in the find­er, you will soon make con­tact with the infa­mous “.DS_Store” files that the desk­top ser­vice lit­ters around as you browse the filesys­tem. This is annoy­ing. Use the above com­mand to delete those suck­ers. The “-print” is in there just so you can mon­i­tor the progress.

Prevent .DS_Store files on network mounts

> defaults write com.apple.desktopservices DSDontWriteNetworkStores true

Although there is no method to gen­er­al­ly stop “.DS_Store” files, at least you can pre­vent desk­top ser­vices from pol­lut­ing net­work mounts. Win­dows users on the same net­work will be glad! This trick is pub­lished in the Apple knowl­edge base [3].

Disable Spotlight indexing for a given volume

> sudo mdutil -i off /mountpoint

This com­mand will dis­able index­ing for the vol­ume under /mountpoint (for instance /Volumes/MyExternalHarddisk). Under MacOS X 10.5 and lat­er, it also deletes any par­tial index cre­at­ed up to this point. There is one caveat: The enable/disable infor­ma­tion is itself stored inside the “.Spot­light-V100” direc­to­ry, so do not delete that, and be care­ful when back­ing up to anoth­er dri­ve. More infor­ma­tion is found in [1].
