Responsive VS Dynamic Web Design

You have just decided on creating a mobile version of your website. Then comes the decision about the most convenient way of its implementation.
There are three to choose from:
mobile URL,
responsive design and
dynamic webpage.
You'll select one, which allows your users to reach target pages and perform actions with minimum efforts. The choice depends on general website structure, types of content and your audience.

A separate mobile URL is the oldest of the three. - If you require major differences between desktop and mobile versions of the website (for example, completely different content), a mobile URL is a good choice; - Your mobile website must be ranked by search engines the same as the desktop one; - If there is only a mobile version of the website, make sure that desktop users are enabled to open it; - There mustn't be chaos in redirects - mobile devices must open the mobile version, while desktops must open the full one; - When there is no corresponding mobile webpage, your mobile visitors mustn't be redirected to another, irrelevant page (for example, main page), where they cannot find the needed information or perform the needed action. Either mobile visitors should be redirected to the relevant desktop page, or there may be no redirect at all; and sending visitors to irrelevant pages perhaps would be the worst decision; - It is also widely recommended to redirect tablet users to the full desktop version of the website.

The other two types of mobile websites share the same single URL for both desktop and mobile.

Responsive design The server identifies the mobile device and its screen resolution, and the content is correspondingly scaled and presented; it can be viewed with any screen resolution, be it a mobile device or a desktop. It has no odd redirects to slow down the loading speed. The lower screen resolution is, the simpler navigation gets. Responsive design is not the best solution for heavy content, such as video - it can slow down the website.

Dynamic webpage The server identifies the mobile device and its screen resolution, and the types of shown content depends on the device. Dynamic webpage is good at delivering heavier content, and it's more difficult in implementation. Here is often used HTTP-header Vary, which prevents the mistake of displaying a desktop page on a mobile device, and vice versa; it also allows Googlebot to find mobile-optimized content faster. If you need to deliver only a part of the desktop content, dynamic webpage is what you need.

Leap Software Developer Program

The 3D motion control company Leap motion has launched its Software Developer Program today and has sent out a letter to developers informing them that they can sign up. The letter also indicates that Leap is now sending out test units to developers who have requested access to the program.
The Leap Software Developer Program is the perfect way for the company to build a stable of apps that use it before it launches to consumers. “The potential is here to bring this revolution into people’s everyday lives,” says Leap in the letter. “We believe this potential can best be reached by working with developers as passionate about the Leap as we are.”

The program includes a Developer Portal and admittance is free. In addition to access to the portal, developers will get:

• a download of the Leap SDK
• access to the Leap API and documentation
• a collaborative question and answer forum
• tools to help drive future development

“In addition,” says Leap, “our Developer Relations team will focus on supporting the Leap developer community, working to continually expand our sample code, libraries, forums, support channels and documentation.”
The developers will not all get test devices right away, says Leap:

A limited number of early members will also receive a fully functional developer beta Leap device. With over 40,000 submissions, we won’t have enough units to offer everyone. But every applicant will be offered full membership in the program over the next few months.
Criteria for receiving early developer units include the clarity of the idea submitted and a track record of developing software. We also want to ensure development for a range of options across games, productivity, education, design and more to be featured in our dedicated Leap app store alongside the customer launch early next year. While we’re excited about all the future uses for Leap, we want to make sure that customers have a great selection of life-changing apps for their new Leap device.

The notifications to developers will continue to be sent out and more will be admitted to the program over the next few months. Leap says that everyone who wants in will eventually be admitted.
Back in July, Leap Motion scored ex-Apple exec and General Partner at Highland Capital (a Leap investor) Andy Miller as its COO. The Leap Motion device can be pre-ordered on its site and developers can apply here.

"Plug and Pray" :^)

This amusing sarcastic name for Plug and Play has become all too commonly heard these days. It refers to the large number of problems associated with getting Plug and Play to work on many systems. It's odd to consider--wasn't the whole point of Plug and Play to make it easier to configure systems? It is, but unfortunately PnP falls short of its lofty goal in many cases.
When you use PnP, you are essentially turning over control of system configuration to the PC. The problem is a common one in computers: the computer isn't as smart as the human, or more specifically, the computer isn't as "resourceful" (no pun intended. :^) ). Computers are not nearly as good as humans at realizing things like this: "Well, if I put the modem at that value and the printer there, I will have a conflict. But I can fix that by changing the assignment for the sound card

, moving the modem over here, and putting the printer there". The system can take care of the simple situations, but can become confused by more complicated ones. The use of multiple "legacy" ISA devices can exacerbate this. Generally, the more complex your setup, the more likely you will need to manual "tweak" whatever PnP comes up with by default.
The biggest problems with Plug and Play revolve around its apparent "stubbornness". At times, the BIOS and operating system seem determined to put a device at a location where you do not want it. For example, you may have a modem that you want at COM3 and IRQ5, but the BIOS may decide to put it at COM4 and IRQ3, conflicting with the COM2 serial port. This can get quite aggravating to deal with. Also, some people just prefer the feeling of being "in control" that they lose when PnP is used. (I must admit to being one of these people, oftentimes.)
The problems with PnP are less common now than they were in the first year that it was announced. As with any new technology--especially one that is as complex as PnP and that involves so many parts of the system--it takes time to iron the bugs out. Most systems today work quite well with PnP. In most cases problems with PnP are due to incorrect system configuration, manual overrides of PnP devices through the Windows 95 Device Manager, or incorrect BIOS settings.

World's First Hard Drive!!

Just Gotta Love Technology!!!!
IBM unveiled the 305 RAMAC on September 13th, 1956. The computer was nothing but a revolution since it could store up to 4.4MB of data (5 million characters) – an enormous amount of data back then. The data was stored on fifty 24 inch magnetical disks. More than 1000 systems were built and the production ended in 1961. IBM leased the computers for $3,200 per month.

Love Buffie

Quote from Buffie:
Does this mean I will never own an Apple product or own a Linux computer? Had you asked me that 6 months ago Iwould have said, "Duh, of course not." But even the hardest of heads can be changed. I now own a computer with Ubuntu and I own 2 iPhones. Will I own an Apple PC?  If donated, I would LOL. Why do I say this? Because my mom was right when she said, "money doesn't grow on trees."  In the future, I may actually buy an Apple PC, but for now I stay with Windows.

The next thing that was asked was, "Do you think there is room for both Windows and Linx?" Absolutely! There are too many nerds in the world to let Linux die. Linux really is a nerd's delight. With the fully customizable atmosphere and the ability to have complete control of your OS, who wouldn't love it? Plus with the user actually dictating what changes need to be made instead of a team of "professionals," Linux holds something Windows will never have: 100% customer backing. The only negative thing I have ever read about Linux, is from users who are less than computer savy.

This brings me to my final point. Windows will be a huge player in the OS world due to ease of use. Not everyone is computer savy and able to do "nerd code". Plus they have things like the automotive industry in their back pocket. Yes even your car runs Windows. But will they always be top dog? That I cannot answer but I suspect if Windows 7 bombs like Vista did, I am putting my money on no. Already Apple is taking a bite out of Windows' profit with mildly funny commercials attacking the PC, playing on the way people have with Vista. Apple is opening the eyes of Microsoft victims to a new horizon. Only time will tell if the Apple will fall from the tree, but I have a feeling the Windows will be shut before long.
Great stuff Buffie!!!  Keep it coming!!!

Intel CPU's

i7-920, i7-965, and i7-975


Intel doesn’t need to launch a pair of new CPUs today. Its thousand dollar Core i7-965 Extreme is already the fastest chip out there by a comfortable margin. Its five hundred-something dollar Core i7-940 slides into second place without an issue. And the company’s entry-level Core i7, the 920, is reasonably priced to the point where it fits into our $1,300 System Builder Marathon parts list (and of course, it also helps that the 2.66 GHz chip approaches 4 GHz with some regularity).

Nevertheless, the company is taking advantage of Computex to launch a pair of fresh Core i7s—the 975 Extreme and the 950. Given their names, you’d think that these newcomers would fall into place on either side of the i7-965. But that’s not the plan at all. Instead, Intel says the i7-975 Extreme will replace the 965 at its exorbitant $1,000 price point and the i7-950 will replace the 940 at $562.


For the time being, 940s will probably float around in the channel at reduced prices. But with i7-920s still the overclocking darlings for less than $300, even a discounted i7-940 would still cost more than we’d be otherwise willing to pay for it.

OSI Model

7-Application
6-Presentation
5-Session
4-Transport
3-Network
2-Data Link
1-Physical


7-The Application Layer

Protocols:
Application Layer
SMB, NCP, FTP,TFTP, NFS. SNMP,Telnet, SMTP

This layer is very closer to user than other layers.in this layer the user interface protocols like FTP,Telnet,SMTP and so on is working.in another word this layer take data from sender system interface and give it to receiver system interface in other side. the Aplication layer interfaces is Winsock And NetBios(microsoft base network only). the applicatio layer protocols often include the session and presentation layer functions.


6-The Presentation Layer

Protocols:
Presentation Layer
NCP, Telnet, FTP,TFTP, NFS, SNMP,SMTP

This layer purpose is to translate the different syntax of systems to the actual syntax of the user system. when the communicating system establish a connection at presentation layer, they exchange message containing information about the syntaxes they have in common, and together they choose the syntax they will use during the session. the sender system send the data in its own syntax and the presentation layer of the sender system translate it to the communication syntax that are chosen before and the receiver system presentation layer receive the data and translate it to its own system syntax and gives it to upper layer(application). another functions of this layer is Compression & Decompression, Encryption & Decryption.


5-The Session Layer

Protocols:
Session Layer
Telnet, FTP, TFTP,NFS, SNMP, SMTP

The session layer allows users on different machines to establish sessions between them One of the services of the session layer is to manage dialoguue control. Sessions can allow traffic to go in both directions at the same time, or in only one direction at a time. If traffic can only go one way at a time, the session layer can help keep track of whose turn it is. Another session service is synchronization. Consider the problems that might occur when trying to do a two-hour file transfer between two machines on a network with a 1 hour mean time between crashes. After each transfer was aborted, the whole transfer would have to start over again, and would probably fail again with the next network crash. To eliminate this problem, the session layer provides a way to insert checkpoints into the data stream, so that after a crash, only the data after the last checkpoint has to be repeated. the session layer provide 22 services but i described some important of that. there are no separate session layer protocols as there are at the lower layer. Session layer functions are instead integrated into other protocols that also included presentation and application layer functions.


4-The Transport Layer

Protocols:
Transport Layer
SPX, TCP, UDP,NetBEUI

The transport layer protocols provide services that compliment those provided by network layer.the difference between the protocols provided at the transport layer within a particular protocol suite(like TCP/IP, IPX/SPX) is that some are connection oriented and some are connectionless. A connection-oriented protocol is one in which the two communicating system exchange message to establish a connection before they transmit any application data. This ensure that the systems are both active and ready to exchange message. TCP; for example, is a connection-oriented protocol wen you use a web browser to to connect to an internet server, the browser and the server first perform what is known as three-way handshake to establish the connection. Only then dose the browser transmit the address of the desired web page to the server. when the data transmission is completed, the systems perform a similar handshake to break down connection. Connection-Oriented Protocols also provide additional services such as packet acknowledgment, data segmentation, flow control, and end-to-end error detection and correction.
Packet Acknowledgment:when a packet from a system sent to another system , the sender wait of the a acknowledgment packet from recipient that are says to sender system the packet are truly transmitted or the packet are damaged. if the packet damaged the sender system must to send the damaged packet again.
Data Segmentation:in the digital technology the main data is split to very smaller pieces that are called packet to transmit in any way.
Flow Control:this is the generation by a receiving of message that instruct the sending system to speed up or slow down its rate of transmission.


3-The Network Layer

Protocols:
Network Layer
IPX, IP, ICMP, RIP,OSPF, EGP, IGMP,NetBEUI, DLC,DECNet

the network layer protocol responsible to end-to-end communications, whereas data-link layer protocols function only on the local lan. the main function of the network layer is Routing. Routing is the process of directing a datagram from its source, through an internetwork, and to its ultimate destination using the most efficient path possible. The network layer determines how messages are routed within the network. It provides transport entities independence from routing and relay considerations, including the case where subnetworks (relay-only) nodes are used. All relay functions are operated within or below this layer. the other function of the network layer is to add a header that are contain the source and destination ip address. another function of network layer is fragmentation. for example, Token Ring frames can be as large as 4500 bytes, but Ethernet frames are limited to 1500 bytes. when a large datagram that originated on a Toke Ring network is routed to an Ethernet network, the network layer protocols must split it into pieces no larger than 1500 bytes each. This process is called fragmentation.


2-The Data Link Layer

Protocols:
Data Link Layer
HDLC, ARP, RARP,NDIS, ODI, LLC, SAP, PPP, SLIP

The protocol at the data-link layer is the conduit between the computer's networking hardware and its networking software. Network layer protocols pass their outgoing data down to the data-link layer protocol, which packages it for transmission over the network. When the other systems on the network receive the transmitted data, their data-link layer protocols process it and pass it up to the network layer. When it comes to designing and building a LAN, the data-link layer protocol you choose is the single most important factor in determining what hardware you buy and how you install it. To implement a data-link layer protocol, you need the following hardware and software: -Network interface adapters (When an adapter is a discrete card plugged into a bus slot, it is referred to as a network interface card or NIC.) -Network adapter drivers -Network cables (or other media) and ancillary connecting hardware -Network hubs (in some cases) Network interface adapters and hubs are both designed for specific data-link layer protocols, and are not interchangeable with products for other protocols. Some network cables are protocol-specific, while others can be used with various protocols. By far the most popular data-link layer LAN protocol in use today (and throughout the history of the LAN) is Ethernet. Token Ring is a distant second, followed by other protocols such as the Fiber Distributed Data Interface (FDDI). Data-link layer protocol specifications typically include the following three basic elements: -A format for the frame (that is, the header and footer applied to the network layer data before transmission) -A mechanism for controlling access to the network medium One or more physical layer specifications for use with the protocol These three components are discussed in the following sections. Media Access Control The computers on a LAN usually share a common half-duplex network medium, which means that it is possible for two computers to transmit data at the same time. When this happens, a packet collision is said to occur, and the data in both packets is lost. One of the main functions of the data-link layer protocol on this type of network is to provide a mechanism that regulates access to the network medium. This mechanism, called a media access control (MAC) mechanism, provides each computer with an equal opportunity to transmit its data while minimizing the occurrence of packet collisions. The MAC mechanism is one of the primary defining characteristics of a data-link layer protocol. Ethernet uses a MAC mechanism called Carrier Sense Multiple Access with Collision Detection (CSMA/CD). Several other protocols, including Token Ring, use a scheme called token passing.


1-The Physical Layer

Protocol:
Physical Layer
CSMA/CD & TokenPassing

The physical layer, at the bottom of the OSI model, is, as the name implies, the layer that defines the nature of the network's hardware elements, such as what medium the network uses, how the network is installed, and the nature of the signals used to transmit binary data over the network. The physical layer also defines what kind of network interface adapter must be installed in each computer and what kind of hubs (if any) to use. Physical layer options include various types of copper or fiber optic cable, as well as many different wireless solutions. In the case of a LAN, the physical layer specifications are directly related to the data-link layer protocol used by the network. When you select a data-link layer protocol, you must use one of the physical layer specifications supported by that protocol. For example, Ethernet is a data-link layer protocol that supports several different physical layer options. You can use one of two types of coaxial cable with Ethernet, any one of several types of twisted pair cable, or fiber optic cable. The specifications for each of these options include a great deal of detailed information about the physical layer requirements, such as the exact type of cable and connectors to use, how long the cables can be, how many hubs you can have, and many other factors. These specific conditions are required for the protocol to function properly. A cable segment that is too long, for example, can prevent an Ethernet system from detecting packet collisions. When the system can't detect errors, it can't correct them, and data is lost. While some aspects of the physical layer are defined in the data-link layer protocol standard, others are defined in separate specifications. One of the most commonly used physical layer specifications is the "Commercial Building Telecommunications Cabling Standard," published jointly by the American National Standards Institute (ANSI), the Electronics Industry Association (EIA), and the Telecommunications Industry Association (TIA) as EIA/TIA 568A. This document includes detailed specifications for installing cables for data networks in a commercial environment, including the required distances from sources of electromagnetic interference and other general cabling policies. Nowadays, in most cases, large network cabling jobs are outsourced to specialized contractors, and any such contractor you hire for a LAN cabling job should be intimately familiar with EIA/TIA 568A and other such documents, including your city's building codes. The other communications element found at the physical layer is the particular type of signaling that is used to transmit data over the network medium. For copper-based cables, these signals are electrical charges. For fiber optic cables, the signals are pulses of light. Other types of network media can use radio frequencies, infrared pulses, and other types of signals. In addition to the physical nature of the signals, the physical layer dictates the signaling scheme that the computers use. The signaling scheme is the pattern of electrical charges or light pulses used to encode the binary data generated by the upper layers. Ethernet systems use a signaling scheme called Manchester encoding, and Token Ring systems use a scheme called Differential Manchester.

Terminal Emulators

More FYI !!!

This post is about video terminals produced by Digital Equipment Corporation (DEC) from 1970 to 1995. The most famous of these is the VT100, a name which is recognized most often today as a setting in terminal emulation programs.

The real video terminals discussed on this web site ( http://vt100.net/ ) were dedicated devices which are connected to a computer (host) with a serial line. They usually consist of a screen and keyboard, with very little processing power and no local storage. Characters typed on the keyboard are transmitted to the host computer, and characters output from programs running on the host are sent to the terminal to be displayed on the screen. Why would we use devices this simple? Well, their simplicity makes them reliable. There is no operating system and no downloaded software, so they are pretty much impervious to user meddling and viruses. Before PCs put computing power on every desk, a central computer would support tens of users. Now that PCs are as powerful as old mainframes and can run capable multi-user operating systems (take a bow, Linux), there is a resurgence of interest in these low bandwidth, low cost and low maintenance devices.

AWESOME !!!
