The entire world is eager to know when will iPhone 5 be released?!  In fact, more people are concerned about iPhone 5 release date than the date when the world will come to an end.  There is just no interest in dying i guess!

Anyhow, according to tradition, Apple usually releases it’s latest and greatest products in June.  However, in case of iPhone 5 and in particular because of extensive marketing and somewhat surplus of iPhone 4 products, they’re looking to hold off until later in the year before the debut of iPhone 5.

Originally, July 2011 was the month when Apple’s iPhone 5 would be released to the public but according to MacRumors, iPhoneSheep.com and representatives of T3.com, the new date although not official, has been set to November of this year.

iPhone 5 comes with some slick new additions and improvements.

The iPhone 5 Features  at a closer view:

• Storage Capacity: Apple is offering 16 GB and 32GB iPhone since 2009, so apple is aware this it would be hard push iPhone 5 without having 64 GB of storage. iPhone 5’s lowest model will come with 32G of space and 64G of memory.
• Signal Strength: Unlike iPhone 4, iPhone 5 is not having signal issue, as they are offering the strongest signal strength of any iPhone model ever even the best of any Smartphone to ever come tomarket.
• Face Recognition: The new iPhone 5 will have Face Recognition for Security sake so that you don’t have to worry about other people stealing your phone and trying to use it.
• Thickness: All three iPhone had thinner bodies than the previous model so the iPhone 5 can be the thinnest yet & much nicer overall body design of the phone.
• Longer Battery Life: iPhone 5 will have Up to 14 Hours of Talk Time On The 3G and 7 Hours on the 4G.
• Video Chat: Video Chat on a 4G network instead of a slow 3G one

Our previous article, 15 Remote Desktop Solutions for Linux generated an unexpected interest within the Linux community.  Many visitors expressed interest on the subject and also pitched in their own suggestions and tools that they use to connect from Linux to Windows and Linux to Mac and etc.

In this article, we’ve come across 15 VNC based Remote Desktop solutions for Linux. It can be used to connect to any VNC server whether it’s on Linux or Windows platforms.

1. MultiVNC – a cross-platform, Multicast-enabled VNC viewer. Features include support for most encodings, ZeroConf service discovery, a seamless edge control mode á la x2vnc, and most prominently, experimental support for VNC via multicast.
2. jOpenRay – project aiming to improve the experience of thin client administrators and users. It deploys in a few minutes, and all you need is Java. It works on Windows, MacOS, Linux, and Solaris. It provides a user friendly interface and tools. It displays Windows XP, Windows Server, Windows Vista, and Windows 7 desktops via the RDP protocol. It displays MacOS, Linux, and Solaris OS desktops via VNC/RFB.
3. noVNC – a VNC client implemented using HTML5 technologies, specifically Canvas and WebSockets. It supports “wss://” encryption (SSL/TLS). For browsers that do not have native WebSockets support, the project includes web-socket-js, a WebSockets emulator using Adobe Flash. In addition, as3crypto has been added to web-socket-js to implement WebSocket SSL/TLS encryption, i.e. the “wss://” URI scheme.
4. RD Connection Manager – a comprehensive remote connection management and publishing solution. It supports the world’s most popular remote desktop management protocols and provides comprehensive functionality to help users and system administrators organize their remote connections in various environments within any organization. Administration is simple with the ability to manage accounts, groups, and permissions. Sensitive data, such as user account settings, are encrypted with SSL. Strong connection security is supported. A single sign on system allows a user to establish multiple remote connections instantly after logging in. Supported protocols include RDP v.5, RDP v.6, VNC, and Citrix ICA.
5. vncssld – a VNC SSL repeater for Unix. You can use it to access your user’s desktop using VNC SSL. The advantage of using a repeater is that you don’t need to configure your firewall to be able to connect to your user’s desktop: both VNC server and VNC client connect to the repeater. Since it is using SSL, It can even work using a standard HTTP/HTTPS proxy (like squid or DansGuardian).
6. The Virtual Machine Manager – a desktop application for managing virtual machines. Since it uses libvirt, it is capable of managing machines from any hypervisor supported by libvirt. KVM and Xen are the current primary targets.The application’s views provide summaries and detailed statistics on performance and resource utilization. A wizard facilitates creation of new guest domains. Console access is enabled either to a text based serial console or fully graphical access via an embedded VNC client. Management of host storage and network interfaces is supported through libvirt.
7. DirectVNC – a client implementing the remote framebuffer protocol (rfb) which is used by VNC servers. What makes DirectVNC different from other Unix VNC clients is that it uses the Linux framebuffer device through the hardware accelerated DirectFB library, which enables it to run on anything that has a framebuffer without the need for an X server.
8. fbvnc – a small Linux framebuffer VNC viewer.
9. GTK VNC Viewer – a script that provides a GUI for connecting to VNC servers. It remembers the credentials of known servers, so connecting to a VNC server is just one double-click away. Servers are shown in an icon view.
10. Conspy – allows a (possibly remote) user to see what is displayed on a Linux virtual console, and to send keystrokes to it. It only known to work with Linux. It is rather like VNC, but where VNC takes control of a GUI, conspy takes control of a text-mode virtual console. Unlike VNC, conspy does not require a server to be installed prior to being used.
11. krd remote desktop connection manager – eases the configuration and utilization of multiple connections to remote desktops. It’s a rdesktop and VNC wrapper. You can configure almost all rdesktop and xtightvncviewer parameters and copy/paste/rename connections. It stores passwords safely with kwallet. You can save/manage sessions very easily using a menu. It supports preinit and postend scripts per connection, typically to start or stop SSH tunnel or VPN connections.
12. Twibright vncrec – a patched vncviewer client that allows producing YUV4 MPEG2 videos from VNC sessions. It is suitable for making instructional, educational, or demo screenshot videos and quickly transcoding into a wide variety of video formats.
13. VncSelector – offers a way to manage a user’s running VNC server sessions. From a single GUI window, it lets you create new instances, connect to an existing instance, or kill existing instances. VncSelector is useful for managing a set of VNC servers on your local machine, and is thus ideally suited for a thin client situation.
14. RealVNC – VNC stands for Virtual Network Computing. It is, in essence, a remote display system which allows you to view a computing “desktop” environment not only on the machine where it is running, but from anywhere on the Internet and from a wide variety of machine architectures.
15. Sun Ray VNC Project – The goal of the Sun Ray VNC Project is a bridging program for the Sun Ray SLIM protocol and VNC RFB protocol based on Linux. A daemon run on Linux, when a Sun Ray Appliance connects to the network, identifies the user by the inserted smartcard, and connects to the preset VNC server. After the connection, via the bridging program between the SLIM and RFB protocols, the VNC’s screen dump will display on the Sun Ray’s display, and the Sun Ray’s keyboard and mouse input will be sent to the VNC server.

MultiTail lets you view one or multiple files like the original tail program. The difference is that it creates multiple windows on your console (with ncurses). It can also monitor wildcards: if another file matching the wildcard has a more recent modification date, it will automatically switch to that file. That way you can, for example, monitor a complete directory of files.

Merging of 2 or even more logfiles is possible. It can also use colors while displaying the logfiles (through regular expressions), for faster recognition of what is important and what not. It can also filter lines (again with regular expressions). It has interactive menus for editing given regular expressions and deleting and adding windows.

One can also have windows with the output of shell scripts and other software. When viewing the output of external software, MultiTail can mimic the functionality of tools like ‘watch’ and such.
