TeamViewer 7 Available, Lots Of New Features

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 situations. The option to display multi-remote screens on a 1:1 scale may be interesting as well to some TeamViewer users.
  • Drag & Drop Even Faster – Simply drag each desired file from and into the remote control window and drop it exactly where you want it.
  • Enhanced Multi-Monitor Support – Do you and your clients both work with two or more screens? Then simply display multiple remote screens on a 1:1 scale on your own monitors – simultaneously and without toggling.
  • Save Connection Settings per Computer – You can now store individual connection settings for each computer in your computers & contacts list. Thereby, saving you valuable time for all further connections to the same computers.
  • Integrated Screenshot Feature – Create a screenshot at any moment during a remote control session. Thus, snapshots of the remote screen are acquired at lightning speed.
  • AVI Converter – Convert your recorded sessions into AVI format and then edit your videos at will.
  • Movable TeamViewer Panel – Position your TeamViewer Panel wherever you like on your local monitors so that you can see every important screen area at any time.
  • Performance Improvement – Especially direct connections and file transfer are now even faster due to optimization of data packets and display settings.
  • Optimized performance with TeamViewer Manager – Huge speed increases, especially for large databases. Through optimized database requests, TeamViewer Manager is now up to 4x faster.

The consultants who give the rest of us a bad name

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 consultant as a fly-by-night, highly paid intruder who waltzes in, sprays his scent on everything, and then leaves the mess for others to clean up evokes recognition in just about everybody who has ever engaged one. That’s a sad state of affairs.

Configuring VLANs for vSphere virtualization

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 switch as a VLAN Trunk Protocol (VTP) port; this is the opposite of the standard cabling that may usually go with a server to the physical switch, the access port (AP).

Defend against Firesheep by surfing securely with HTTPS

Defend against Firesheep by surfing securely with HTTPS: "
Filed under: ,
Firesheep Sucks, DeviantArt user MyBlackSheepThe 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

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 advertizing and so is the installation. You get a quick download in a .zip file and then simply double-click the .exe file to start the installation. This application does not open automatically after installation, but does offer a desktop icon for easy access. You can download RMPrepUSB from this link: http://www.rmprepusb.tk/
The interface is straightforward and fairly self explanatory. If you want an instructional manual, there is one available at the link provided, though you might have to search around a bit. The site gets changed often and updated versions are consistently released. It is best to use the latest version.
In order to create a bootable USB, first do the obvious and insert a blank USB drive into your computer. Using this application is so basic and easy that anyone can do it (yes, really). The interface displays a list of bootloader options to choose from. By default, the Image Tools setting is set for File to USB.
usb boot type
The File to USB option reads the image file content then writes to the selected drive. Only binary images will work and they cannot be compressed. The USB to File option reads file content and then writes it to an image file. With either option, supported image formats are IMG, ROM, BIN, RAW, BMDK, VDI, RAM, QCOW, QCOW2, CLOOP, DMG, VPC, VHD, VVFAT, and NBD. File Info option is included so that you can obtain file information.
Select the desired bootloader and then choose a file formatting system in the field just below the BOOT TYPE list.
If the USB that you are using has any files or portable applications on it, they will be erased once you create the bootable USB. That is why using a blank USB drive is emphasized. RMPrepUSB automatically formats the drive and, as we all know, formatting erases all data.
Once you have selected the format and the bootloader, all you need to do is click Prepare Drive at the bottom pane. This will initiate the process to create the bootable USB for the selected operating system. You will see a warning stating that all data will be erased and it will ask if it is OK to do so and create a new partition.
Click OK and the application process will start. When finished, it will show that the bootable USB was created. If you want to test it, there is a Test button in the right pane. The only catch is that testing also erases the USB and you have to start over, but it is good to do this to ensure that it is working properly.
device quick test
Once tested successfully, start over and then you have your bootable USB.

Intel apresenta protótipo do Knights Corner, processador com mais de 50 núcleos

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.

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 operações de ponto flutuante por segundo. Esta capacidade praticamente o coloca em pé de igualdade com o supercomputador K, atualmente, o mais rápido do mundo.

Para tanto, chips Knights Corner responderão por 80% do processamento do supercomputador. O restante ficará a cargo dos processadores Xeon E5, que deverão estar amplamente disponíveis no mercado no segundo trimestre de 2012.

Com tecnologia de 22 nanômetros, o Knights Corner será fabricado com base na arquitetura Many Integrated Core (MIC) e terá núcleos com frequência entre 1 e 1,2 GHz. Além disso, contará com um acelerador capaz de melhorar a performance de aplicações com processamento paralelo. Sua capacidade de processamento individual está estimada em 1 teraflop.
