Who is not familiar with Facebook, Social Networking Sites Network No. 1 in the world. Behind all that what really makes up can still survive with the number of users to date? Let’s look

As a social networking site that has millions of users, must have been up to have activity that is very dense. As quoted from Pingdom Sunday (17/10/2010), up to serve at least 570 billion page views every month. In addition, there were approximately 3 billion photos uploaded every month by all users. That’s what makes up a large enough number of servers, which is about 30 thousand servers that existed until 2009.

The role of hardware in support of the existence of facebook is important, but behind all that the role of software is also important to maintain the viability of the social networking site. Software what is this?

Memcached, is a hash or associative array that can store data, such as string, integer or even objects. Hash data is stored in computer memory (RAM) to very fast to access.

HipHop for PHP, the application is responsible for converting the PHP programming language into C + +. So that will accelerate the processing of data within Facebook.

Haystack, this application is in charge of storage images in the database up. For information, Facebook has 80 billion photos in various resolutions. So it takes an application that really tough to manage.

BigPipe, this application serves to fix a bug or a syntax error on facebook

Cassandra Apache, is a database application based Bigtabel’s data. This is the facebook application that is used for storage of billions of data to date.

Scribe, is a social publishing site, where tens of millions of people to share original writings and documents.

Hadoop, Cassandra’s application is similar to Apache which aims for data storage facebook. Apache Project is an open-source implementation framework for a reliable, scalable computing, and distributed data storage

Hive, is a data warehouse built by the Hadoop infrastructure that provides tools to enable the summary data, ad hoc query and analysis of data stored in Hadoop file.

Thrift is a software development framework for cross-language services. This software combines a software stack with the code generation engine to build services that work efficiently, such as C + +, Java, Python, PHP, Ruby, Erlang, Perl, Haskell, C #, Cocoa, Smalltalk, and OCaml

Varnish, is a key software that speeds up your website. This is Open Source, built on industry standards and requires very little resources

Since Thursday night, January 27, 2011, appeared in Egypt complaints that internet access in the country started to experience interference. The action was deliberate by the Egyptian government, which cut off almost all Internet access and communications to prevent a wave of massive demonstrations, which were still happening on Friday.

According station Al Jazeera news, about 88 percent of Egypt’s internet connection totally paralyzed. Computers in homes, offices, and business places, government offices and even rumored to not be able to access the Internet throughout Friday. The Internet is still able to function in a very limited, such as stock exchange or military facilities.

“This is an action that does not alleged in the history of the Internet,” the statement Renesys, an Internet monitoring firm in the United States (U.S.) in response to a mass blocking internet connection by the Egyptian government.

Time magazine pages reveal how the government or the authorities have the ability to do blocking access. This is what happened in Egypt with crippling internet connections in their countries in response to the turmoil of the people, who demanded President Hosni Mubarak to step-down.

The average individual’s computer to gain access to the virtual world through an internet service provider (ISP) local. Local ISP then connects directly with a variety of similar providers across the world.

When opening a page and write the domain address in the address bar, such as Facebook or Twitter, the local ISP instantly submit any connection to the ISP that is used up so that the view will be directly available on the monitor.

Computers that are connected with the page requested will send a response to a local ISP, which in essence stated, “Yes, we’ve connected. This is the page requested.”

Blocking is also determined on whether the server is active on domain name system (DNS). The computer will be identified by numerical code, called internet protocol (IP) address.

This system will determine whether the access request to a page via the ISP would actually connected or not appear at all. If the DNS server is not working, then there will be no response from the destination pages.

The Egyptian government could cut off all Internet access with enough deadly DNS servers use a local ISP. So, every request to a specific page from a computer in Egypt will not be fulfilled because no DNS servers that facilitate the request. Demand for entry into the local pages in Egypt from any computer abroad will not work.

In Egypt, all ISPs should be subject to government policies, including when to shut down DNS servers that are used for the public. According to BBC news station, one of the leading ISP in Egypt, Vodafone, was claiming that they received instructions from the Egyptian government to shut down their DNS servers.

“Under the law in Egypt, authorities have the right to issue such orders and we are obliged to obey,” Vodafone said in a statement.

The same instructions apply to other ISPs. Not surprisingly, internet access in Egypt paralyzed.

However, cut off the internet network in egypt is almost over for days can interfere with the economic situation in the country. In almost all countries, information technology such as the internet has become an important element to drive the economy.

“It’s just a matter of time before the internet back working in Egypt,” said Sheriff Mansour, observers of the Freedom Watch, as quoted by Wired.com. “Governments also need the internet to drive the economy, investment, and operate,” said Mansour.

Action phishing or sensitive information theft attempts targeting bank customers have repeatedly occurred. Here are four tips that could hold onto customers so as not to fall for the trick-trick this action.

1. Origin Check Email
Usual mode waged cyber criminals is to send an email teaser to a number of people. The contents of electronic mail will usually ask the prospective victim to visit a particular site, to then re-register (include your username and password e-banking customers.)

Well, for those customers do not necessarily believe if you get an email with a model like this. First check the origin of the sender’s email, if using an official email domain from a particular bank or not.

Because, if they use the email domain is not clear, it need not be trusted email. Although at the end of their email claim from the concerned bank.

2. Not Quite through Email
Re-register by entering your username and password is a sensitive activity. Thus, delivery of information related to this activity cannot be arbitrary, only via email.

A number of banks admitted if they want their customers to re-register, they usually do not just let me know via email. But also through more personal means, namely contacted directly. There also are using an official letter, although the combined-match with the email as well. At least, the bank treats these events with more professional.

3. Reverse Phone
Do not hesitate to call customer service bank you use. Better to be alert, rather than hesitate, but instead led to bad things for you.

4. Distinguishing Genuine or Fake Site
Sites that financial institutions use to login normally have a security system tighter. First, see the website address. Site logins should use the prefix ‘https’ instead of ‘http’. Https is a secure version of http.

Suffix ‘s’ in ‘http’ indicates that these sites actually have ‘secure’, because the technology is protected by Verisign SSL encryption of data.

In e-banking site of Bank Permata the asphalt, also contained the logo ‘Security VeriSign Site’. To the layman, it would be difficult to distinguish. That can be one benchmark validity of an e-banking site is the URL that is written is ‘https’.

Then at the bottom right of the browser (for Firefox) there is a locked padlock image. As for Internet Explorer (IE), this yellow padlock in the URL field.

Similarly, four short tips to help readers in warding off the threat of phishing activity. Although impressed simple but the impact to be provided by actions that are not aware of this, it will be fatal.
If the victim involuntarily fills your username and password in asphalt sites, it can be ascertained that such personal data, including records e-banking activities of his, will be known by other parties who are not responsible.

The research teams led by Vijay Erramilli from Telefonica Research in Spain create a derivative Twitter named Social Network Write Generator (SONG) to conduct research on human interaction.

To generate the data, SONG walk with the help of 16 Pentium computers connected to each other. Computer 16 is then worked simulate the network in ‘twinning’ Twitter is.

Reported by New Scientist and quoted on Wednesday (02/09/2011), in his research, the research team collected 12 million tweets written 2.4 million people on 25 November to 4 December 2008.

“After analyzing them, it was found that the level of tweet generally formed during the day, then going down at night. But the emergence of this tweet too often up and down in ways that can be predicted from a matter of seconds to hours,” said Erramilli.

In this experiment also found that by gradually increasing the number of tweets per second, the CPU is overloaded because it causes intermittent network at 100 tweets per second.

‘Twitter’ is then the total dead at 150 tweets per second. So you can imagine how many units of data processing required for the site for Twitter.

Erramilli mention, SONG can be used as a model for the analysis of Twitter. The reason, this mini version of the Twitter model easier than examining research using original Twitter tweets that contain activity within a very massive scale.

“The results of analysis can be used to help the company advertisers, website maker, and other businesses that intend to use Twitter,” lid Erramilli.

Wow, today I am very happy … hahaha why? because I just read the news in detik.com, if jengkol stock is back to normal, what does it mean? jengkol price will be cheap again.

Some like jengkol? Otherwise you do like it, be grateful to people who’ve ever felt pleasure of jengkol.

Because talking about jengkol, I try a little review about the food “delicious smell bringing” a much-loved by the people of Indonesia

Jengkol, smell but there Benefits

If you are a fan of traditional food, you definitely know the object that is round flat, thin brown skin, smells and consumed a lot of people. The object is Jengkol. Jengkol or Jering or Pithecollobium Jiringa or Pithecollobium Labatum is typical of plants in the Southeast Asian region, including the popular in Malaysia, Thailand and Indonesia particularly in West Java, which consumed 100 tons a day.

Jengkol plant a tree whose height can reach 10-26 feet. The fruit is a pod-shaped flattened and convoluted. Dark violet fruit color. After dark, the fruit pods into convex shape and in a place that contains the seeds of its size enlarged. Each pod can contain 5-7 seeds. Ari seeds thin-skinned and shiny brown.

Jengkol will create excitement when cooking it and after processed by the digestive tract, which is causing the smell that he is not tasty. The cause of the odor is actually the amino acids contained in the seed jengkol. Amino acids were dominated by amino acids containing sulfur (S). When degraded or fragmented into smaller components, amino acids it will produce a variety of flavor components is very smelly, due to the influence of the sulfur. One of the gases formed by the element that is very famous H2S odor.

Odor generated from jengkol it’s actually quite disturbing, especially for others who do not eat. If you are eating, although the smell, at least, have enjoyed the delights jengkol. But for others who do not participate feel, but just miss the smell, would feel very disturbed. Especially with the release of urine. If this jengkol eaters pee in the toilet and rinse it less than perfect, then the toilets will smell unpleasant and disturbing the peace of others.

When digested jengkol will leave a substance called jengkolat acid (jencolid acid) are discharged into the kidney. This is where the effect is often feared by the people, namely jengkoleun or jengkolan. Jengkolan jengkolat occurs when acid that is difficult to dissolve in water eventually settles in the kidneys, forming solid crystals can result in difficult to dispose of urine. If our blood pH neutral, acid jengkolat safe, but if you tend to be acidic (pH less than 7) jengkolat acid to form insoluble crystals.

Jengkolan risk is not dependent on the number jengkol consumed, but depends on the vulnerability of a person’s body. Susceptible people, eating less jengkol alone can cause jengkolan. What affects one’s susceptibility to acid jengkolat unclear, but presumably due to genetic and environmental factors?

Behind the odor generated jengkol, it contained useful benefits for health. According to various studies show that jengkol also rich in carbohydrates, protein, vitamin A, vitamin B, vitamin C, phosphorus, calcium, alkaloids, essential oils, steroids, glycosides, tannins, and saponins.

Especially for the content of vitamin C contained 80 mg in 100 grams of seed jengkol, while the nutritional adequacy of the recommended rate per day is 75 mg for adult women and 90 mg for adult men.

In addition, Jengkol a good source of protein, which is 23.3 g per 100 g of material. Protein content far exceeds the tempe which is known as a source of vegetable protein, which is only 18.3 g per 100 g. Protein needs of each individual, of course, vary. In addition to helping the growth and maintenance, the protein also serves to build enzymes, hormones, and immunity of the body. Therefore, the protein substance is often called the builder.

For iron, Jengkol containing 4.7 g per 100 g. Iron deficiency can cause anemia. The symptoms of people suffering from iron deficiency anemia are fatigue, weakness, pale and less passionate, headaches and irritable, unable to concentrate, as well as susceptible to infection. Patients with chronic anemia showed shape like a spoon and brittle nails, cracked at the corners of the mouth, tongue, difficulty in swallowing.

Adolescents, pregnant women, nursing mothers, adults, and vegetarians are most at risk for iron deficiency. In the body, iron partially located in red blood cells as heme, a pigment-containing nucleus of an atom of iron.

Jengkol also very good for bone health because of the high content of calcium, which is 140 mg / 100 g. The role of calcium in general can be divided into two, namely helping the formation of bones and teeth, and regulate biological processes in the body.

The biggest is the purpose of calcium during the growth period, but consumption in adulthood is quite highly recommended to maintain bone health. Consumption of calcium is recommended in adults is 800 mg per day.

The content of phosphorus in jengkol (166.7 mg/100 g) is also very important for the formation of bones and teeth, as well as for storage and energy expenditure. Thus, actually many benefits derived from eating jengkol and this is just the input only, not a doctrine that requires you to believe and follow for consuming jengkol, but you just know that there are benefits behind this smelly vegetable pods.
