I choose my words carefully. Please read them carefully. 1. My argument was never about the quality of open-access journals. Given the choice between a closed journal and a "lesser" open-access journal, most (but not all) authors

The added value of publishers is more than just the editing. Why do you think a published paper is "worth" more than a pdf on a random website? - Almost nobody in academia is willing to publish in substandard journals only because

Sure. The modern TeXs (xetex, luatex) take unicode input. Also for math. That makes the text even nicer looking. But most editors are inconvenient for finding the right characters.

Can we have the inverse transformation also? So \alpha would become a unicode α and \int would be ∫. Emacs has an input method that does the transformation automatically [1]. Yet most of my collaborators have not yet caught that bug.. [1]

That's why the link to foobar turns up in people's search results.

No puzzle here. You can only log in if Google has flagged your search topics. On google search, you have the variable window.location.search = "?gfe_rd=cr&ei=XXXGyZiVNHoFcuF8Qe7wYHACw&gws_rd=ssl" That string is appended to

True. Valgrind slows things considerably. In the end, what to use is a matter of workflow and convenience. Good to know how tcmalloc makes debugging memleaks easier. Just for for completeness, a third option would be a tracing tool that hoo

Have you tried valgrind for this?

It's different. But it is definitely not shit. The majority of use shouldn't write code like this. But those who can create amazing things. Here's a working adaptation that is quite close to the original. https://g

Uuh. This is ancient K&R C. Here's a version that is somewhat closer to todays C. https://gist.github.com/jpfr/560c861cd3eb76700a54 Can we replace some of the one-letter codes with better namings?

Besides emacs 24.4 being an awesome release by itself, it also means esr can finally transition the development to git. That will render the project a lot more accessible for new developers and ad-hoc bugfixing.

LTTng is closely related to liburcu (now on http://urcu.so/ ). It provides lockless datastructures for screaming fast concurrency on multicore machines. You will be pleasantly surprised by the concurrent hash-map implementat

The term 'real-time' is used _very_ loosely here. In industrial settings, in order to claim realtime-properties, you need to make guarantees about the runtime behavior of server, client and the network infrastructure in between. I

See the paper linked in the post below. It deals with exactly that 'economic approach' in addition to traditional repositioning with trucks. But with positive customer incentives instead of added costs. There's a freely acces

At one point they had nearly 30 repositioning trucks in London (2-3 years ago). At Waterloo Station they basically hand them off trucks directly to the arriving customers during rush hour.

I recently published on the same topic. [1] In many bike sharing systems (such as in London), there is a daily repeating cycle, where too many people want to get to the city center in the morning and back out in the early evening. You know
