C’est une question que je me pose réellement et j’aimerai avoir un maximum de réponse à cette note (faites passer autour de vous).

Quand j’étais jeune je me souviens qu’en cours de math c’était un exercice type : “et à la fin la machine combien elle produit de pièce dans la journée”. Bon c’était pour nous apprendre la multiplication et la division. Quelques années plus tard on nous apprenait que c’était valable dans un système sans interdépendance ni variabilité.

Mais l’exercice était toujours le même et concernait une machine ou une personne effectuant une tâche répétitive, parfaitement connue, “scriptée”, invariable. Et il s’agissait souvent d’une tâche finale ou intermédiaire dans un processus de fabrication qui permettait à la fois d’identifier un produit et lui donner une valeur.

Aujourd’hui la productivité du collaborateur est un enjeu majeur et d’ailleurs tout le monde à ce mot à la bouche. Mais force est de reconnaitre qu’au delà des mots la définition du Saint Graal est on ne peut plus floue. Tout le monde veut être plus productif, veut que les autres le soient. Mais sans trop savoir au final ce que ça signifie ni être clair sur la réponse à “on le mesure comment ?”.

Alors j’aimerai savoir comment vous déterminez votre propre productivité et celle de vos équipes. Temps de présence actif ? Nombre de tâches effectuées (mais qui de la nature variable ou non des dites tâches) ? Valeur créée ? Objectifs atteints ? Trouvez vous votre mode de mesure satisfaisant ou est-ce un pis-aller ?

Tous vos retours sont les bienvenus…. Faites passer le message car plus j’aurai de retours plus on aura une base de réflexion intéressante.

Netbooks are all the rage at the moment, with Asus predicting that it will sell 5 million of its Asus Eee PC netbooks by the end of this year. However, one of the tricky aspects of netbooks is that they have much more limited hardware resources than larger, traditional notebooks. For that reason, it makes sense to put applications on your machine that are both lightweight and powerful. The good news is that many of the best choices are free. In this post, you’ll find 10 ways to pimp out your Windows or Linux netbook, without breaking the hardware resources bank.

OpenOffice Whether your netbook is Linux- or Windows-based, one of the best free downloads you can get is this suite of open-source productivity applications. OpenOffice includes lightweight but robust applications that compete with the expensive Microsoft Office alternatives: Writer (word processing), Calc (spreadsheet), Impress (presentations), Base (database), Draw (diagram creator) and Math (editor for math formulas).

PortableApps For Windows-based netbooks, this is a great collection of pre-selected free and primarily open source applications that you can stick on a netbook — or even a USB drive — in one quick download. It includes the portable editions of ClamWin (antivirus), Mozilla Firefox (web browser), Gaim (instant messaging), OpenOffice (office suite), Sudoku (puzzle game), Mozilla Sunbird (calendar/task manager) and Mozilla Thunderbird (email client), among other applications. You can cherry-pick the applications you want, or run the whole suite in under 512MB.

Google Chrome I usually favor Firefox when using a high-end computer or laptop, but on a netbook, Google’s open source Chrome browser is an extremely lightweight browser that is winning lots of speed competitions. It’s only available for Windows for the moment, but will be out in a Linux version early next year.

LXDE The “Lightweight X11 Desktop Environment” is a fast, energy-saving Linux desktop environment maintained by an international community of developers. It has a slick interface and lots of useful features, including tabbed file browsing. Plus, it takes fewer resources than the popular KDE and GNOME Linux desktop environments.

GNOME The GNOME desktop environment is very popular with many Linux users, and is lightweight enough for netbooks. Within GNOME, you get e-mail, groupware, web browsing, file management, multimedia, games and more. The new version 2.24 includes the GNOME Mobile Platform for the first time, which will keep developers focused on mobile applications for GNOME on an ongoing basis.

KDE The K Desktop Environment (KDE) Project is a very good choice for Linux-based netbooks. It includes slick desktop applications, including the Kontact personal information manager, Dragon Player for multimedia applications, and the Konqueror web browser.

RocketDock RocketDock is an animated application launcher that I highly recommend for owners of Windows-based netbooks. It is much faster and more flexible than the object docks on most netbooks, and it has an easy drag-and-drop interface. Check out a video of it here.

TinyResMeter TinyResMeter is a lightweight application for tracking system resources in use. Netbooks, of course, often have stripped down hardware resources, so this is a good way to get on-the-fly views of memory usage, CPU usage and much more. Keeping it on hand will help you stay under the system resource wire.

VLC Media Player Depending what hardware resources you have on your netbook and the media player you currently use, you may occasionally run into problems running video and audio content. VLC Media Player is a lightweight, free and open source media player that will work on either a Windows or Linux netbook. It supports nearly every popular file format and is specifically designed for portability.

Online Hosted Apps. Of course, one of the fundamental concepts behind netbooks is that you can use them with applications that are hosted online. If you don’t already use these, there are excellent, free choices from Zoho and Google Apps. Ulteo gives you 1GB of free online storage, and access to all of the OpenOffice productivity apps online.

Finally, don’t forget that a USB thumb drive can be an excellent adjunct to your notebook. You can get lots of capacity for very little money, and one simple download such as the PortableApps download above can put countless free applications in your pocket for use on your netbook whenever you want.

De Rebus Antiquis Et Novis writes about the math factor of this year's constitutional changes in Russia and the politicians' “most stupid explanations for their controversial decisions”: “Is it that me and Grigori Perelman are the only Russians who understand that the only way to ‘ensure a difference in time between the elections' is to make the terms equal?”

Paying for college is expensive. GradeFund, a startup founded by a couple of brothers from Harvard and Princeton, has an interesting new approach to covering at least some of the costs: rewarding students monetarily for making good grades.

GradeFund isn’t actually issuing the payments, but they’ve setup a system where students can find people to sponsor their good performance in class. For example, students can set a goal of making an A in Physics, get a friend, company, or otherwise able donor to support it, and if the student succeeds (as verified by transcripts), payments are sent either directly to the student or to the respective university on their behalf.

Why would a sponsor want to invest in a student? Aside from family or community members that simply want to support someone they know, GradeFund wants to appeal to corporate sponsors looking to develop students with specific skillsets, potentially as a gateway into hiring them into their company. Rather than sponsor a specific student, GradeFund also lets donors put money towards a specific cause, like rewarding students for making good grades in math and science courses.

It’s an interesting model. Hundreds of millions of dollars are already donated to universities and scholarship funds every year, but GradeFund gives donors very specific control over where their money goes. On the other hand, it does appear to be a for-profit venture (GradeFund takes a small transaction fee), but that shouldn’t discourage most sponsors from using it considering the amount of money that goes to administrative costs through traditional donations.

The Harvard Crimson has a bit more about the venture and its founders.
