Twitter to increase your site visitors

I have been using Twitter for a while, but I haven’t really been as fascinated as the rest of the world (or at least so it seems). To me, Twitter has just been a cool tool that I sort of used for a few weeks, until I found myself asking; what’s the point?

I am still asking that questions, but now, I have at least found a way to attract visitors to my blog using Twitter. It works, and it’s completely free.

I have signed up at twitterfeed, and I added the feeds to my blogs. That took me about 20 seconds. Yes, that’s actually it.

What twitterfeed does, is that it displays your blog posts at Twitter. Every time you publish a new post, all your followers will get the message. They’ll see your title, a short description and a link to the post. It’s all 100% automated.

This is not cheating, even though it sort of feels like it. This is more like a new way of posting messages to your “friends”. You do it from your blog instead of using your mobile phone, instant message client, web browser or e-mail.

You are letting them know what you are doing, you are staying connected with your “friends”, family and co-workers, and that’s the whole point about Twitter or am I still missing something?

But remember, Twitter is not just about one-way communication. You should still look at other people’s messages and be active, that’s the only real way to get massive traffic from Twitter.

Hi Definition Blu Ray disc Technology


Optical disks have come a long way. They began back in the 1980s with the Cd, which was great for music, computer software and data. Unfortunately, it was useless for movies. Dvd came to the rescue in the 1990s, with capacity enough room for movies - great! But then, along came high definition video, and for that the DVD was just plain rubbish.
But then, in the new millennium, the invention of a marketable
blue laser diodeprovided the eureka for optical disks. Brighter, thinner blue lasers gave far better definition and accuracy than the old CD/DVD red lasers. Now a disk the same dimensions as a DVD could carry many times more data.
Consumers looked on with hope. True to form the industry leaders around the world leaped into action and collaborated to create... an almighty mess.
Two competing formats emerged,
HD-DVD and Blu-ray, both vying for market supremacy. Championed by media and technology giants on both sides, it was a close run thing for years. When HDDVDfinally capitulated in November 2008 Blu-ray became the industry standard for blue laser optical disk technology. With 100GB capacity, live web interaction and high definition, surely the Blu ray disc is the future?

180 Surveyillance camera


To cover a 180° field of view, most surveillance cameras either swivel on remote-­controlled mounts, which means they can miss suspicious activity, or use fish-eye lenses, which can introduce distortions. A new camera stitches images from five inexpensive, fixed sensors--the same kind used in camera phones--into a single, undistorted 180° picture. The Ethernet-connected device is the size of a light switch and transmits video at 15 frames per second, along with a seven-megapixel still image every second or two.

Hard Disks

HDDs record data by magnetizing ferromagnetic material directionally, to represent either a 0 or a 1 binary digit. They read the data back by detecting the magnetization of the material. A typical HDD design consists of a spindle which holds one or more flat circular disks called platters, onto which the data are recorded. The platters are made from a non-magnetic material, usually aluminum alloy or glass, and are coated with a thin layer of magnetic material. Older disks used iron(III) oxide as the magnetic material, but current disks use a cobalt-based alloy
The platters are spun at very high speeds. Information is written to a platter as it rotates past devices called read-and-write heads that operate very close (tens of nanometers in new drives) over the magnetic surface. The read-and-write head is used to detect and modify the magnetization of the material immediately under it. There is one head for each magnetic platter surface on the spindle, mounted on a common arm. An actuator arm (or access arm) moves the heads on an arc (roughly radially) across the platters as they spin, allowing each head to access almost the entire surface of the platter as it spins. The arm is moved using a voice coil actuator or in some older designs a stepper motor.

Older drives read the data on the platter by sensing the rate of change of the magnetism in the head; these heads had small coils, and worked (in principle) much like magnetic-tape playback heads, although not in contact with the recording surface. As data density increased, read heads using magnetoresistance (MR) came into use; the electrical resistance of the head changed according to the strength of the magnetism from the platter. Later development made use of spintronics; in these heads, the magnetoresistive effect was much greater that in earlier types, and was dubbed "giant" magnetoresistance (GMR). This refers to the degree of effect, not the physical size, of the head — the heads themselves are extremely tiny, and are too small to be seen without a microscope. GMR read heads are now commonplace.

HD heads are kept from contacting the platter surface by the air that is extremely close to the platter; that air moves at, or close to, the platter speed.[citation needed] The record and playback head are mounted on a block called a slider, and the surface next to the platter is shaped to keep it just barely out of contact. It's a type of air bearing.

The magnetic surface of each platter is conceptually divided into many small sub-micrometre-sized magnetic regions, each of which is used to encode a single binary unit of information. In today's HDDs, each of these magnetic regions is composed of a few hundred magnetic grains. Each magnetic region forms a magnetic dipole which generates a highly localized magnetic field nearby. The write head magnetizes a region by generating a strong local magnetic field. Early HDDs used an electromagnet both to generate this field and to read the data by using electromagnetic induction. Later versions of inductive heads included metal in Gap (MIG) heads and thin film heads. In today's heads, the read and write elements are separate, but in close proximity, on the head portion of an actuator arm. The read element is typically magneto-resistive while the write element is typically thin-film inductive.

In modern drives, the small size of the magnetic regions creates the danger that their magnetic state might be lost because of thermal effects. To counter this, the platters are coated with two parallel magnetic layers, separated by a 3-atom-thick layer of the non-magnetic element ruthenium, and the two layers are magnetized in opposite orientation, thus reinforcing each other.Another technology used to overcome thermal effects to allow greater recording densities is perpendicular recording, first shipped in 2005, as of 2007 the technology was used in many HDDs

Modern drives also make extensive use of Error Correcting Codes (ECCs), particularly Reed–Solomon error correction. These techniques store extra bits for each block of data that are determined by mathematical formulas. The extra bits allow many errors to be fixed. While these extra bits take up space on the hard drive, they allow higher recording densities to be employed, resulting in much larger storage capacity for user data

The memristor, a microscopic component that can "remember" electrical states even when turned off. It's expected to be far cheaper and faster than flash storage. A theoretical concept since 1971, it has now been built in labs and is already starting to revolutionize everything we know about computing, possibly making flash memory, RAM, and even hard drives obsolete within a decade.
The memristor is just one of the incredible technological advances sending shock waves through the world of computing. Other innovations in the works are more down-to-earth, but they also carry watershed significance. From the technologies that finally make paOffice a reality to those that deliver wireless power, these advances should make your humble PC a far different beast come the turn of the decade.
In the following sections, we outline the basics of 15 upcoming technologies, with predictions on what may come of them. Some are breathing down our necks; some advances are still just out of reach. And all have to be reckoned with.
