Serviciul de filehosting, Rapidshare limiteaza viteza pentru conturile free astfel incat viteza maxima care poate fi atinsa este de 30kb/s, potrivit Geek. Pe langa limitarea vitezei, mai exista si o alta limita, astfel incat un utilizator care foloseste un cont free nu va putea pune pauza pe descarcare. Insa poate sa existe pauza oricand intre server si client, iar timpul descarcarii va creste considerabil.
Incercarea de a-si mari numarul de utilizatori cu cont premium ar putea avea insa efecte contrarii pe termen mediu si lung. Daca totusi vreti sa folositi serviciul oferit de Rapidshare va trebui totusi sa achizitionati lunar sau annual un pachet Pro. Pretul incepe de la 13 $ pe luna, pana la 130 $ pentru doi ani de zile.
Nu ar fi exclus ca in urmatoarele luni sa se inchida si acest site de filehosting, dupa ce acum o luna de zila s-a inchis Megaupload.

1. The output of the Router# show interfaces serial 0/1 command displays the following:
Serial0/1 is up, line protocol is down.
What is the most likely cause for the line protocol being down?
Serial0/1 is shutdown.
There is no cable connecting the routers.
The remote router is using serial 0/0.
No clock rate has been set.
2. Which address can be used to summarize networks 172.16.0.0/24 thru 172.16.7.0/24?
172.16.0.0/21
172.16.1.0/22
172.16.0.0 255.255.255.248
172.16.0.0 255.255.252.0
3. 
Refer to the exhibit. How will packets destined to the 172.16.0.0 network be forwarded?
Router1 will perform recursive lookup and packet will exit S0/0.
Router1 will perform recursive lookup and packet will exit S0/1.
There is no matching interface associated with network 172.16.0.0 so packets will be dropped.
There is no matching interface associated with network 172.16.0.0 so packets will take gateway of last resort and exit out S0/2.
4. A static route that points to the next hop IP will have what administrative distance and metric in the routing table?
administrative distance of 0 and metric of 0
administrative distance of 0 and metric of 1
administrative distance of 1 and metric of 0
administrative distance of 1 and metric of 1

The Apache Software Foundation has announced the release of version 2.4 of its namesake Apache HTTP Server. The new version is the first major release for Apache since 2005. During that time several new servers, including the increasingly popular Nginx server, have emerged to challenge Apache’s dominance. However, while Nginx may have surpassed Microsoft IIS to become the second most used server on the web, it still trails well behind Apache, which powers nearly 400 million web sites.
To upgrade your servers to the latest release, head over to the Apache HTTP Server Project and download a copy of Apache 2.4.
Much of the focus in Apache 2.4 is on performance. The Apache Software Foundation blog touts reduced memory usage and better concurrency among the improvements in this release. Apache 2.4 also offers better support for asynchronous read/write operations and much more powerful Multi-Processing Module (MPM) support. Multiple MPMs can now be built as loadable modules at compile time and the MPM of choice can be configured at run time, making Apache 2.4 considerably more flexible than its predecessors.
There have also been numerous updates for Apache’s various modules, as well as a host of new modules that are available with this release — including mod_proxy_fcgi, a FastCGI protocol backend for mod_proxy.
For a complete rundown of everything that’s new in Apache 2.4, be sure to check out the documentation.

Gruparea Anonymous a spart site-ul Institulului National de Cercetare si Dezvoltare pentru Optoelectronică (INOE) din Romania si a postat pe internet aproape 2000 de fisiere confidentiale. Anuntul a venit din partea grupului de hackeri printr-un mesaj postat pe Twitter.
"De două zile încercăm să câștigăm o luptă pe apele învolburate ale internetului, și iată că am reușit. De această dată, forțele noastre au atacat siteul INOE, alături de subdomenii importante ale acestuia", se arată într-un post al facțiunii românești a Anonynmous.
Hackerii au reusit sa descarce de pe serverele INOE aproximativ 2,8GB de informatii. Site-ul INOE in acest moment este inaccesibil.
Anonymous a publicat, pe site-ul său, linkuri pentru descărcarea documentelor confidențiale.

Voi ce ati alege intre cei doi antivirusi ? sau poate recomandati altceva. De preferat ar fi sa va si argumentati optiunea.
Astept comentariile voastre.
