Cyberspace : What is Cyberspace ?

Cyberspace is made up of two words – Cyber and Space. This is used to indicate a space over internet where online communication can be done. The first serious formulation of the concept of Cyberspace can be found in 1964 in Stanislaw Lem’s book Technologiae Summa, where the concept of cyberspace is described under the name Peripheral Phantomatik. Another serious formulation of the Cyberspace concept can be found in Oswald Wiener’s book, the improvement of central, novel of 1969, notes the sections on concept of the bio-adapter. Literal meaning of cyberspace came in the short story Burning Chrome (1982), an American science fiction by the author William Gibson. Gibson describes cyberspace as a consensual hallucination in a computer-generated graphical space.

What this Cyberspace Actually is ?

With time in real, the vague, ill-defined terminology cyberspace by any means do not suggest a world on Internet composed of virtual reality, Virtual Reality is a fully different service or structure and often uses different web based software for a target audience. The confusion with the terminology Cyberspace went to be more intense in early nineties of past century when Autodesk launched a product named Cyberspace.

Cyberspace and 5 Layer Model

2 years back, in October 4, 2010, an article was published on ; they described the flow of information in to have 3 characteristics – semantics (the meaning of information), syntax (information flow) and lexical (stock information).

They describe 5 stages or layers in this way :

  • The cybersocle
  • Cyberprimaire: the emergence of human language and meaning
  • Cybersecondaire: the emergence of writing and mathematics
  • Cybertertiaire: global interconnected men
  • Cyberquaternaire: the man-machine convergence

It will be an transliterated republication (which we avoid) if description is given, you can read in details about these 5 ayers of Cyberspace with the help of Google Translate :

Probably you got more confused with the meaning of Cyberspace now after reading this article. That is normal as various meta morphological things are revolving around it. But clearly, Internet is not Cyberspace – this was what we wanted to point out.

Basics of Supercomputer

Supercomputer is super as it is the fastest computer of its time. It does not matter, which architecture a supercomputer is based on. A typical feature of a modern supercomputer is its large number of processors on the common peripherals and a partially shared memory access. Supercomputers are often used for computer simulations and in the field of high performance computing. This article is named as Supercomputer Basics as there are many tit bits of a Supercomputer which can not be covered in one article in details. We will give an idea of a Supercomputer in this article, which is understandable to any class of reader. Later, as usually we will go in to details of Supercomputer.

Basics of Supercomputer

It is quite important to understand how the processor of a computer works. There can not be any special build fast processor for a supercomputer, that is why all the supercomputers are parallel computers . A parallel processor is a computer, in the operations simultaneously on multiple CPUs will be distributed in order to increase the operating speed. For the optimal use of a super computer programming must therefore be matched as closely as possible to the individual, parallel processors. Originally, the outstanding performance was achieved by maximizing the utilization of available technology, the number of processors was more moderate. The major problem of adding numerous processors is huge electricity consumption and resultant heat. ISRO and Indian Institute of Science, India is in the way to develop the fastest supercomputer which can perform at 132.8 exaflops. SAGA-220 is also by ISRO, performing at 220000 220 TFlops. It actually uses ~400 NVIDIA Tesla 2070 GPUs and 400 Intel Quad Core Xeon CPUs. This will give you the real image of supercomputer.

Features of a Supercomputer

A supercomputer has processing speed of billions of floating point instructions per second, can handle up thousands of users in large network environment, require special facilities for air conditioning industry. It is very important in the field of research, as it provides high-speed calculations processing, for example, can calculate the human genome sequence with a very low margin of error and they can cost up to tens of millions of dollars for each.

Operating System of Supercomputer
Mostly Linux and Linux-derivatives.

Usage of Supercomputer
Supercomputers are used to address complex problems or can not be performed well in the physical world, either because they are dangerous, involving things incredibly small or incredibly large. Using supercomputers, the researchers modeled the climate of past and present and can predict of far future climate. Astronomers and space scientists use supercomputers. Most common usage of supercomputer is in military and higher health researches.

On Demand in Computing : What On Demand Means ?

On Demand in Computing, specially in Cloud Computing this word on demand is frequently used. On Demand has more than its literal meaning. In cloud computing, on demand does not always actually means – if the owner own a certain limit – that is the demand. No, that on demand is basically literal meaning, the phrase on demand in computing has more deeper meaning.

On Demand in Computing : Beyond Cloud Computing

On Demand is not only for Cloud Computing, it is for networking, it is for any science which runs on logic and a pattern of equation can be written. In case of distributed computing, on demand is a general terminology that is used for request served from a server computer to a client computer. It is usually on HTTP GET request. When the user is not using, the demand is lost. Demand lost means – increase in computing resource pool. There can not be any computer or server setup in this World with endless computing resources. On Demand is like an equilibrium with a certain number of users who will always use, it is the absolute number, not specific user; certain number will suddenly increase the work burden. This is the reason, on demand depends on Scalability. Mystically, Scalability and Service Continuity are not equivalent. This is the reason why, most high end research universities, who needs high end computing resources, are using Cloud Infrastructure over distributed computing as in distributed computing the on demand is actually limited too much. On demand is not unlimited in cloud but assured to have virtually endless computing resource.

On Demand in Computing : Examples

The Cloud platform this website is on, has practically endless computing resource. It is impossible to use 30 GB of RAM, 5 load balancers. They are resting as there is no demand. When we will publish this post, there will be a sudden gush of visitors from various social networks, it is configured in a way, the provisioning will also increase proportionately. As Server means hardware, if the hardware behind is crap, the network connections are not optimal, no theory will work.

Another good example of on demand computing is – the technology today’s most mobile broadband uses in HSPDA or higher configuration. If you are not doing anything, like just loaded this website and no other active internet activity, you will notice that, despite your HSPDA can give 7.2 Mbps speed, it will fall back to few kbps. When you will open YouTube, that on demand will work to boost up the speed to few Mbps. They do not always use the phrase on demand, sometimes uses speed throttling synonymously. This is why with Internet Load Balancing, one can virtually have endless dependable speed only bounded by physical hardwares.

Our body has millions of distributed computing system and not all works – fever, pain are on demand as the end response. If I slap you, your adrenaline glad will pour its content on demand in your blood stream and in return, you will get more energy (more glucose in circulating blood, rise in BP) to slap me more hard, the end result what we say – my head got hot. It gets hot on demand to execute an emergency work. Head actually gets hot literally, if you get angry, test by putting your hand over your head, it will feel warm. The energy produced is lost as heat plus there is more circulation of blood on demand. If you get scared, reverse will happen, on demand system by default will fail. How there will be provisioning for escape, that is a separate story.

XenoForo Should Follow the Trend of Free Software for Survival

XenoForo Should Follow the Trend of Free Software for Survival or rather to deploy the biggest possibility of catching up the market in Forum Software. Free Forum Softwares which has better possibilities to get a big market are MyBB and BBPress. XenoForo basically followed the old marketing model of paid software of vBulletin which invariably will not work in next five years. It is what statistics is saying – CentOS versus Red Hat, competition less WordPress, the rise of Ubuntu, Android OS, Open Stack, Rackspace Private Cloud Computing software aka a version of Open Stack, Open Swift deployment, Red Hat’s Open Swift. vBulletin is useless in terms of solid HTML output, imbecile licensing costs and important XenForo is in backfoot.

Why XenoForo Should Follow the Trend of Free Software for Survival

MyBB, BBPress and SMF – three big blasts in 2012, in terms of coding has progressing very rapidly. MyBB by default offers three database options – PostgreSQL, MySQLi and MySQL. XenoForo is good looking, option rich and suitable on the Cloud. Three important related articles to this post will be :

XenoForo Should Follow the Trend of Free Software : Unlimited Developers and Less Legal Dispute

The major trend of Internet (in Google Search World) was backlinking and huge number of posting. That has been slashed by Google with latest intelligent authorship based, rich snippet based ranking. Those are old domains running vBulleting will probably not suffer due to a constant supply of visitors from social media, but definitely, today one successful WordPress owner with Google Verified Authorship will think 5 times whether to use BBPress or MyBB. This is because the codes are clean and safe – they are open and can be modified easily. I personally do not use any Forum Software as our platform is blogging.

vBulletin however, trying their best to knockout XenForo from legal ground (check WikiPedia article on Xenforo). But vBulletin’s idea is wrong. Just two days ago we tested MyBB for tutorial purpose and we were quite astonished with their progress. We have been used with space, line break free HTML output from WordPress. XenForo is closer but needs solid coding. Kier Darby has 1261 followers, Mike Sullivan condition is worse – 598 followers. They could easily follow the path of Matt Mullenweg, instead thought of temporary gain of wealth but killed the impassibility of becoming hero.

Hundreds of good paid softwares died before or got sold, if XenoForo does not follow the trend, their death is inevitable, today or tomorrow.
