TeamViewer 7 Available, Lots Of New Features : TeamViewer is without doubt one of the most popular remote access and support applications. Part of the software’s success stems from the fact that it is free for personal use and portable if needed. Nothing beats installing TeamViewer on family or friend computer systems to save time fixing computer problems. TeamViewer 7 is now available for Windows, Mac and mobile operating systems such as Android or Apple’s iOS. The Linux download page lists version 6 as the latest. The developers have added a lot of new features to the remote access software. It is a long list divided into the two core areas Remote Control and Meeting. Remote Control All users benefit from performance optimizations. Especially direct connections, file transfers and working with TeamViewer Manager have seen performance improvements. The new media features, e.g. screenshot creation during remote control sessions or the AVI converter make life easier in specific s...

The consultants who give the rest of us a bad name : " It’s like deja vu all over again . The first thing out of your prospect’s mouth — no, wait… the first thing was “Hello” and introductions, the second thing was “Would you like a cup of coffee?” So the third thing out of your prospect’s mouth was about how the previous consultant screwed everything up. They want to know if you can fix it. I always feel a little bit like the Next Duchess in these conversations. While I know that the prospect holds high hopes that I’ll be their saviour, they’ll also be watching my progress with a jealous eye — ready to strike me down at the first hint of trouble. It’s pointless to try to tell them that I’m not like that other guy. I’ve got to prove it. This wouldn’t happen if the majority of consultants performed their duties conscientiously. If a bad egg floated to the surface now and then, we’d have no worse reputation than regular employees. As it is, the characterization of the...

Configuring VLANs for vSphere virtualization : " VMware’s vSphere virtualization suite allows for ESXi hosts to support 802.1Q VLAN tagging, which presents multiple networks to the virtualized infrastructure. The basic premise is that a virtual switch (either the standard virtual switch or the new vNetwork Distributed Virtual Switch) will be presented with a tag (a VLAN ID) to the ESXi hosts. The use of VLANs for virtualization functions in a very similar way that the network switches move multiple networks around the datacenter between other switches. With a VLAN configured, the ESXi host can present multiple networks to all types of communication. For example, the ESXi management interface can have an IP address on one network, while the vmkernel vMotion interface can be configured for a separate IP address on a separate network; both networks can be configured on the same physical cable with the use of VLANs. You would need to configure the physical cable on the physical sw...

Defend against Firesheep by surfing securely with HTTPS : " Filed under: Security , Browsers The last couple of days have seen the launch and explosive proliferation of a Firefox add-on called Firesheep . It's an incredibly simple program that snoops unsecured Wi-Fi packets to grant you one-click masquerading of other users: if you log into Facebook at the local coffee shop, someone can use Firesheep to become you . Seriously, you can go along to any location with an unsecured Wi-Fi network and steal other users' accounts. Firesheep does this by 'scooping' cookies out of the air. Whenever you log into a website your name and password is only sent once -- afterwards, a stored authorization token is used. This means that if someone has your cookie they can pretend to be you -- and with unsecured wireless networks, anyone can grab your cookie .

Create Bootable Windows or Linux USB with RMPrepUSB : Of the various applications for creating bootable Windows or Linux drives, RMPrepUSB offers some unique features which may be appealing to many users. Advanced users can set specific parameters for the drive if necessary. New and inexperienced users can easily use this application as well. Unlike other similar applications RMPrepUSB has additional features that stand out. There are options for USB formatting in several file systems such as FAT16, FAT32 and NTFS formats. You are able to run a USB speed test, size/speed test, install Grub4dos, SYSLINUX, and even create AXT2 FS on any USB drive. This is much more convenient than creating bootable disks on CD or DVD, as pen drives are much easier to keep track of and less prone to damage. This application is completely free with no catch and you don’t end up with a dozen different toolbars in your browsers or applications that you don’t want. The download is free of advertizin...

Intel apresenta protótipo do Knights Corner, processador com mais de 50 núcleos : Recentemente, a AMD anunciou um processador com 16 núcleos (Opteron 6200) que estará disponível no mercado em breve. Quase que ao mesmo tempo, a Intel apresentou um protótipo do Knights Corner (nome provisório), um poderoso chip que poderá contar com mais de 50 núcleos. Rajeeb Hazra, gerente geral do Intel Technical Computing Group, com um protótipo do Knights Corner (Imagem por Intel) Mas não se trata, necessariamente, de uma corrida para definir qual o processador com mais núcleos, já que ambos os chips têm focos diferentes. Enquanto que o Opteron foi desenvolvido para servidores utilizados em aplicações de cloud computing , o Knights Corner está sendo preparado para equipar supercomputadores, como o Stampede , da Universidade do Texas (Estados Unidos), que deverá entrar em operação em 2013. O Stampede deverá trabalhar com até 10 petaflops, ou seja, poderá processar mais de 10 quatrilhões de ...
