Mendeley is joining Elsevier…

Mendeley is a serious options for those looking at a PDF management (and in text citation) system for scientific literature. It is a rather good option to replace the old-timer Endnote.

Remember that EndNote is a product of Thomson Reuters; you know Web of Science, Impact Factor and so on.

Well, Mendeley is now part of the Elsevier family, another major player. It is going to be interesting where this will lead Mendeley in the longer term.

Alfred 2 is here!

For a long time, I used Quicksilver until it went un-supported for some time (or let’s say less supported for a while). Nowadays, I use Alfred. Alfred is Spotlight on steroid and makes multiple actions and workflows accessible via keystrokes. Version 2.0 is now out and Cult of Mac has a nice article: Great Workflows To Help You Get More Done With Alfred 2.0 [Feature] | Cult of Mac.

Online Collaborative Writing using LaTeX

LaTex / TeX has been a favourite of scientists for a long time. For many, TeX typesetting is considered to be producing the most beautiful and elegant documents, in particular when equations are involved. On OSX, I used over the years tetex and TeXLive in the past. Nowadays, MacTeX appears to be a popular package.

Beside the beautiful and elegant documents it produces, LaTeX uses only ACSII characters. It is thus highly portable and fully compatible across platforms. Therefore, documents can be written in any text editor (from the lowest common denominator such as vi to more elaborate one such as Emacs. On OSX, you will find the beautiful Aquamacs version of Emacs.

However, collaborative writing in LaTeX might not be the most intuitive function of LaTeX/TeX packages. And while I do hate WORD, its visual change tracking system makes document sharing and collaborative writing quite easy (compared to performing a “diff” command on two files and so on…If you do not know what is the “diff” command, it further proves the point).

Welcome to the free WriteLaTeX online collaborative environment. This new service was pointed out to me recently by a colleague at my institution. It is a web-based service and thus cross-platform and fully compatible with tablets (either iOS, Android or Blackberry) and no need to install a standalone distribution. Your working space is 100 Mb with the possibility to increase to 1 Gb (in steps of 50 Mb per referral…). Figures in JPG, PNG and PDF are supported as well as bibTeX bibliography style. Furthermore, writeLaTeX let you do Beamer presentations as well!

Are your Cloud data really safe from prying?

This article from Cult of the Mac report on the legality of the US Government to access data from non-us citizen on any US based Cloud-type storage services (not just iCloud as mentioned in the title) without a warrant. This does means DropBox, Google Drive, iCloud and so on.

It is not ok to forget basic math…

Is it ok to forget basic math simply because we are reporting to readers some information on the web? I am asking because today Apple was announcing its quarterly numbers and the first reports from specialists were not even able to get the math right. This is rather discouraging considering that this is their full time work for most.

In nutshell:

  • 4.2 billion$/week in revenue vs 3.3 billion $/week in revenue for same quarter a year ago
  • 13.08 billion in total profit over 13 weeks versus 13.06 billion $ for the 14 week quarter a year ago.

This is where the problem start, reading the so-called “serious” news outlet. In term of revenue, the YOY increase is about 27% which is rather impressive for a mammoth-like corporation in this economic context. However how many of these analysts, those providing readers with advices with regards to what to do with their money, have written in the minutes after Apple’s announcement that the profits were flat (or even declining), thus …

I am not an economist but I would grade that statement with a failing mark would it be a math exam. I would certainly expect a high school student to get this right.

13.08 billion over 13 weeks is 1.006 billion $ / week while 13.1 billion over 14 week is 0.933 billion $ / week. This actually translates to an increase in profit of about 7.8% YOY. This is not a flat nor decreasing scenario anymore.

We can of course argue about the significance of this increase (and this is not the place to do so!) but at least we are comparing and reporting the right information. Everything else has nothing to do with hard numbers 😉
