Apple A7 chip and iOS 7 thorough reviews available…

For those of you following the tech world, in particular computers, the announcement of the A7 64 bits SoC probably got a WOW out of you. It did for me. To me screen size, phone shape and the same has nothing to do with innovation. The issue of 4″ vs. 4.5″ vs. 5″ screens is like preferring a 13″ vs. 15″ vs. 17″ notebook or a 50″ vs. 65″ TV set. However, screen technology providing rendering image, resolution, contrast, color delivery (gamma, …), lower power consumption and the combination of all of them and more that is innovation. The same for custom, optimized and powerful SoC chips that drive these micro-computer… errr smartphone.

Quite frankly looking back at computing since the Z80, TRS-80 and commodore when I started on my first computers, the power packed in commercially available device of such as small format as the iPhone 5S, fitting in one’s pocket and working for hours before recharge, is absolutely amazing. In addition it delivered to the general public a 64 bits platform along with the OS and numerous apps (all of Apple apps on the iPhone 5S have been recompile in 64 bits). It might not register as a big deal to most phone users but it is from a technological standpoint. Also interesting that ARM was joint venture between Apple and two other companies in part to produce power efficient chips for the Newton, such a long time ago it seems.

A very interesting review, with benchmarks, can be accessed at AnandTech. We will certainly know more when someone actually get a layout of the chip (from high-res X-ray), but still very interesting. The review also look at the integrated camera and fingerprint system. Another interesting read is Daring Fireball takes on 5S new technologies.

Today was also the public release day for iOS 7 (like it or not!). Ars Technica published an in-depth-review.

Good reading 😉

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!
