virtual desktop

virtual desktop and Cloud computing

The second framework for virtual desktops is much newer and, for many organizations, more exciting. Cloud computing is a form of IT resource hosting in which the computing platform (hardware, storage, OS) is hosted. In cloud computing applications, the company committing to cloud computing supplies applications that "run in the cloud."

The resources of a cloud network form a pool that's available (based on policies) to any user or application. This not only generates the best possible economy of scale, it also increases reliability and availability, accommodates shifts in demand that come with time zone changes, etc. A cloud computing environment is to an enterprise data center what the Internet is to a leased line.

The largest benefit of cloud computing, in supporting the notion of a virtual desktop, is that cloud computing has no specific limitations on applications, number of users, traffic volumes, etc. The resources in the cloud are elastic, so demands can be expanded and reduced as business activity dictates. Applications could, in theory, run in a variety of places worldwide -- with computing power migrating around the cloud to support all of the business' needs. However, this is only in theory because there is no determined standard for what constitutes cloud computing, not even to the point of defining its necessary properties. There are no set methods to interface with applications in the cloud, no rules on storing data or adding or removing processing capacity. Each cloud computing framework has its own rules and procedures for controlling resources, and each will have its own structure of charges as well. Fortunately, there are some factors that emerge as common capabilities -- and issues -- as you leave the cloud and approach the virtual desktop.

Cisco for PHP

This PHP class provides connectivity to Cisco switches and routers.  It was written out of necessity (because I refuse to use Perl) and has become the foundation for many of my operational systems.  In hopes that it will be useful for others, I've made it available here under the GNU General Public License.

API Reference Documentation

This Cisco PHP class uses Telnet to connect to IOS-powered devices.  While many prefer to use pure SNMP for device management, I've found that for many operations SNMP is too costly in terms of CPU load on the device, and too slow for time-sensitive applications.  As a result, this class does a lot of text parsing.

I try to test this class against the following Cisco devices: Catalyst 2960, 3560, and 3750 series switches, Catalyst XL-series switches (3500-XL, etc.), 3550 series switches, 6500 series switches and routers, 7200 series routers, 7600 series routing switches, 1800, 2800, and 3800 series routers, and legacy routers like the 1720 and 3600.  Though my primary focus is the 3560 and 3750 series switch.

For most operations, data is returned in an associative array. When an operation returns several pieces of data, it returns an array of associative arrays (2-dimensional array) making it easy to manipulate the data in your application.

Cisco SSH for PHP

For those interested in an SSH version of this class, I have been working on an implimentation that makes use of phpseclib.

The following is an archive of the pre-release cisco_ssh class with a modified phpseclib (several fixes have been made to phpseclib that are not included in the current release).

What Are the Benefits of Green Coffee?

What Are the Benefits of Green Coffee?

While traditional black coffee is made from roasted coffee beans, green coffee beverages are made using the unroasted, or “green,” coffee beans. Extracts from green coffee beans have demonstrated many health benefits in scientific studies. The main components of green coffee responsible for these benefits appear to be caffeine and chlorogenic acid, a type of antioxidant, although some effects are influenced by factors other than these compounds.
According to a study published in March 2006 in “BMC Complementary and Alternative Medicine,” daily supplementation of an extract prepared from green coffee beans reduced body fat and body weight in mice, as well as fat composition in the liver. The effect was similar in mice supplemented with isolated chlorogenic acids and caffeine, which suggests that these are the compounds responsible for the effect. Chlorogenic acids found in green coffee can be digested and absorbed by humans, which implies a similar availability as the extract.
Reduction of High Blood Pressure

In addition to its effects on promoting weight loss, chlorogenic acids in green coffee can reduce blood pressure. According to a study published in 2006 in “Clinical and Experimental Hypertension,” patients supplemented with 140 milligrams of green coffee bean extract per day demonstrated reduced blood pressure throughout the study. No side effects were reported, which suggests that green coffee is a safe way to help reduce high blood pressure.
Improved Mood and Cognitive Performance
The caffeine found in green coffee has a positive effect on your mood and brain activity. According to a review published in February 2008 in “Nutrition Bulletin,” several studies have confirmed that caffeine can improve reaction time, vigilance, memory, alertness, focus, fatigue resistance and other factors of cognitive performance. Reviewers found the optimal intake of green coffee to be between 38 to 400 milligrams per day, or between approximately 1/3 cup to four cups of brewed coffee.
Benefits From Antioxidants

Green coffee beans and their derived products contain multiple antioxidants, which are compounds that reduce the effects of cell-damaging free radicals in the body. This preventative function keeps you healthier by reducing the amount of damage and stress your cells can take. According to a study published in July 2004 in the “Journal of Agricultural and Food Chemistry,” chlorogenic acid antioxidants in green coffee beans could prevent the proliferation of four kinds of cancer cells, suggesting green coffee may be useful in preventing some types of cancer.

Cucumber best kidney cleanser in town

Cucumber, best kidney cleanser in town

The flesh of cucumbers is primarily composed of water, thus consuming cucumbers can keep the body hydrated and help regulate the body’s inner temperature. This vegetable’s high water content gives it a very unique moist and cooling taste.

Apart from the fact that cucumbers are 95 percent water, they are a very good source of the vitamin C, molybdenum, vitamin A, potassium, manganese, folate, dietary fiber, magnesium and silica.

The silica in cucumber is an essential component of healthy connective tissues, which includes muscles, tendons, ligaments, cartilage, and bone. Cucumber juice is often recommended as a source of silica to improve the complexion and health of the skin.

In addition, cucumber’s high water content makes it naturally hydrating and “a must for glowing skin”. No wonder it is said that “there is nothing more nourishing for the skin to have than the liquid juice from the cucumber”.

The nutrition-rich water that it contains, adds tone to the skin, sparkle to the eye, colour to the lips and luster to the skin. Cucumbers are also used for treating skin problems like swelling under the eyes and sunburn.

The vitamin C (ascorbic acid) and caffeic acid prevent water retention, which may explain why cucumbers applied topically are often helpful for swollen eyes, burns and dermatitis.

Adding a cucumber to your salad is an especially good way to increase your fiber intake, which helps to reduce constipation and also offer some protection against colon cancers.

Fiber adds bulk to your food, cucumbers can make you fuller for a longer time. In effect, this very low calorie vegetable (just about 15 calories per 100 grams) can come in handy as a snack for dieters.

Cucumbers have the reputation as the best kidney cleanser known. This is because they help to wash the kidneys and bladder of debris and stones. Studies have shown that eating cucumbers regularly helps to regulate uric acid in the body, thereby preventing certain kidney and bladder stones.

Cucumbers’ diuretic properties probably due to its high water content, coupled with its potassium content helps to reduce high blood pressure and heart rates by counteracting effects of sodium.

This cool, crunchy vegetable has high amounts of vitamin K, about 17 mcg per 100 grams, which has been shown to have potential role in bone mass building, making it a good snack for middle aged and elderly women with osteoporosis. So would you rather take the cooling, refreshing, water-rich, filling, low-calorie cucumber or the next available pastry when you feel like snacking?

5 Million Gmail Usernames And Associated Passwords Leaked

It's time to change your Gmail password -- again.

Around 5 million Gmail usernames and associated passwords were leaked on a Russian Internet forum on Tuesday.

Thankfully, less than 2 percent of real, current username and password combinations, or about 100,000, were released, Google's Spam & Abuse Team wrote in a blog post. Many are old and many don't match -- for example, the user name is for Gmail, but the password is for Facebook.

If your current Gmail password and username were compromised, Gmail would have let you know by now.

"It’s important to note that in this case and in others, the leaked usernames and passwords were not the result of a breach of Google systems," Google wrote. "Often, these credentials are obtained through a combination of other sources."

Hackers may have gotten these names and passwords from other sites. If people used the same usernames and passwords on Gmail as they do on a site that was hacked, your Gmail could be compromised. We've said it before and we'll say it again: don't repeat or reuse passwords.

There's a link being passed around called IsLeaked.com, where you can allegedly check to see if your Gmail was hacked. DO NOT DO THAT!

Some point out that the website launched right before the hacks, and may be a trap to gather more email addresses.

When in doubt, just change your password.

5G test

Nokia to build a 5G test network

The remaining, or “original” Nokia, the portion of the Finland-based icon that was not acquired by Microsoft still has a major role to play in mobile even though it is not making phones, and more than simply providing maps.

The part of Nokia that remained Nokia has a well-established networking unit that used to be a partnership with Siemens. Nokia bought out Siemens’ share of the company and what was once known as Nokia Siemens Networks, is now Nokia Networks.

Nokia Networks builds switchgear that mobile carriers use to manage and grow their networks. Competitors are other well-known names like Ericsson, Alcatel-Lucent, and Huawei. All these companies will play a role in determining the standard that will become the fifth major generation in wireless communication, called affectionately, 5G.

Nokia is going to build a test network in Oulu, Finland early next year. As the data transfer test network develops, Nokia has also stated that it will share the APIs with invested partners and even competitors. The goal is to shape a new collaborative model. This is a good thing, as it will probably mean there will be fewer growing pains among any competing standards that may emerge.

There is no firm specification for what 5G will be. Most ideas appear unified to being able to provide 1,000 times the capacity of today’s LTE networks, and data throughput somewhere between 10 and 100 times the common data rate today. Energy consumption will definitely be part of the standard, with a goal to reduce it by as much as 90%. Expectations are also being made that latency will be reduced by about five times, end-to-end. Those are some impressive numbers to look forward to. It should mean data speeds in excess of 500Mbps, and latency in the sub-20-millisecond range.

Nokia has already been in discussions with NTT DoCoMo about the next generation of wireless. Samsung will be joining Nokia as a part of DoCoMo’s 5G trials in Japan. Most believe we will see the first commercial deployments of 5G in place by the year 2020.

LuneOS

continue Web OS  project For  smart phone

LuneOS 

Open WebOS, the open-source port of the former Hewlett-Packard and current LG platform, has a new name.

OpenWebOS is now LuneOS, the team behind the platform announced on Monday. The full name was previously "WebOS Ports Open webOS" -- something that the group behind the mobile operating system said, "wasn't very catchy."


OpenWebOS was an offshoot of WebOS, the mobile operating system initially developed by Palm and transferred to HP when that company bought Palm in 2011. Although both HP and Palm attempted to get WebOS off the ground, both companies failed, and HP eventually open-sourced the operating system.

It was at that point that the team behind Open WebOS got to work on developing an alternative mobile operating system. It was also after that that LG acquired the rights to WebOS. The company is currently exploring its usage in televisions and other consumer electronics devices.

With LuneOS comes some improvements to the platform. The first release is being called "Affogato" and its stability has been improved for use on smartphones and tablets. The group behind LuneOS says that while its platform can work on the Google Nexus 4 and HP TouchPad, as well as the Galaxy Nexus and 2012 Nexus 7, its goal is to make it easy to port to other devices

"Our main focus is not to add new devices as they appear on the market but instead to provide a stable, easy to use and easy to port software base," the group said.

It's also worth noting that LuneOS is not designed to take on iOS and Android. Indeed, the backers say that they're "not trying to reach feature comparison with Android or iOS."

Looking ahead, the team behind LuneOS is hoping to improve the project and bring more people into the fold. The group said that it's "small" and working on "a large project."

"We have a lot of parts on the service side in place but the app UIs need a lot of work from creative people," the group wrote in an announcement on Monday. "If you like webOS, know how develop on the web and enjoy working with an enthusiastic team on a new community built mobile operating system, don't hesitate to contact us through the available communication channels."
