When Reality Hits ITIL - Implementations

Is implementing ITIL really simple? It is easy to hear about ITIL from a
consultant or read from a blog or even attend an ITIL course, but the
hardest part comes while implementing those processes in an environment.
Each and every organization is different; they vary with people,
processes, environment, type of support they provide, help desk and much
more. This white paper is intended to help the IT managers to self assess
their help desk and its maturity level in order to implement the right
process at the right time.http://www.manageengine.com/products/service-desk/itil-reality.htmlcontact us for detail:Fanky Christian

New LMS from Instructure Goes Open Source

A Utah-based company has fired a warning shot across the bow of learning
management system (LMS) companies, including market leader Blackboard,
with the announcement that it's turning its new LMS into open source.
Instructure has publicly released the source code to its Canvas learning

currently evaluating its application."We're excited to offer an alternative to the current LMS options," said
Josh Coates, Instructure's CEO. "We want to open up the market to allow
for innovation so teachers and students can be at the forefront of

"Netbook" dengan Material Ramah Lingkungan

KOMPAS.com — Mempertimbangkan spesifikasi teknis saja rasanya tak cukup dalam memilih netbook. Kini, perlu dipertimbangkan apakah material netbook yang akan dibeli cukup ramah lingkungan. Sebab, apa gunanya spesifikasi bagus jika proses produksinya ternyata merusak alam.

Bagaimana caranya memilih netbook dengan material yang ramah lingkungan? Hasil Greenpeace Electronics Survey 2010 mungkin bisa memberikan panduan. Greenpeace menilai berbagai perangkat produk dengan kriteria yang ketat.

Berdasarkan hasil survei itu, Acer TravelMate Timeline X TM8172 dikatakan sebagai yang paling baik. Entah mengapa produk ini masuk kategori netbook mengingat layarnya 11,6 inci. Hasil penelitian menunjukkan bahwa netbook ini paling sedikit mengandung material berbahaya. Material berbahaya yang masih digunakan di netbook antara lain PVC, BFR, Antimony, Phtalate, serta Beryllium.

Greenpeace memberikan skor 28 untuk keramahan lingkungan material pembuat netbook ini. Skor tersebut hanya 2 poin lebih rendah…
