Week 5 Blog 3: Automatic Analyzing Songs Using Machine Learning Algorithms
Computers have made big changes in musical industry. Right now, people can find music by their title, type of genre, name of artist, but they are not able to recommend a good tune. There are plenty of recommendation systems for music listener. For example iTunes recommends songs to the user based on comparing the collection of other user. Now researchers are using machine learning algorithms, “in combination with a Facebook game, to classify music based on the automated analysis of the songs.” The researchers want their system to be able to not only tag songs with title or artist but they will be able to tag by genre, instrument, and descriptive words. Researchers are gathering information by using a game called Herd It. I believe in order to encourage people to play this game, they will award users points when they tag songs in a similar way to other user’s tagging. Using most of machine learning algorithms, in order to give the satisfy results, required lots of sample data. Once the data is collected, first they group the songs, it’s given the same tag by users and then applies a statistical analysis to the waveform patterns, and they will look for common feature between the songs with same tag. The researchers believe that the system has commercial potential. The system expected to take an unfamiliar song, from anywhere, and suggest appropriate tag and similar music. Lots of companies who were even trying to reach to this goal long time ago, before this research like Pandora, the Internet radio site, has done this but 100% manually by getting help of their users. Other company like the Echo Nest is working on automatic analysis of music. They are transforming the waveform patterns of songs based on what is familiar to human ear and then combining that information with tagging information gleaned from blogs and other posted on the Internet. Then they apply machine learning algorithm to identify feature of songs that are associated with specific tags. As researchers expect the automatic analyzing the song will increase as the demand for song is going up and sites will encourage users to tag and find new music in order for the researchers get the better results in their field of research by using machine learning algorithms. I as one of the user who do not listen to music that often or not looking for any special or new music that are coming out because of not being familiar with singer’s name or the albums. I believe this research and the system that are coming up with will encourage me to look for music and listen to it. Because I believe this system even help the user to save the time and make decision much faster. The usage of this algorithms will make searching much faster and gives more accurate recommendation.

Week 5 Blog 2: Installation of Windows Update Without User Permission
Windows surprised lots of their users by downloading windows updates without asking any permission. The people who are get surprised are the ones who had set up the operating system to ask them for permission before installing any updates or patches. Lots of users who have mentioned above noticed after June 9th, their computers start windows updates and set of security patches when they are rebooting or turning on their computers. This will happen when windows determine new patches, then sometimes it will show update icons in the task bar. That’s the case when you are rebooting or turning on, those update will be installed without caring about the permission part. I believe this bug should be solved and windows should not be able to decide to install the updates. One of the reason, that I agree with, is that Microsoft released numerous versions of patches on the same date. And in one of the article mentioned, the extra demand for downloading patches and updates, may have caused some downloads to be incomplete. Also Microsoft Support Document admits that “incompletes downloads are known to disable the notification icon and possibly the approval dialog that's supposed to appear during shutdown.” Microsoft manager denied the updates issues were a bug. Paul Pottorff, a senior product manager with the Windows Update team, said "[But] If there is only a throttled update, they shouldn't be notified. If there are any other available updates, they should be notified. The presence of a throttled update does not prevent Automatic Updates from notifying users about other not-throttled updates. Furthermore, this behavior has been the same for a long time and hasn't even been touched for more than 9 months." This problem of updating without permission is not something new and the same kind of problem had happened on 2007. In the article there are some notes on how to control windows updates. I believe since windows had that update, their teams should be familiar with this kind of bug and try to avoid having that bug in the patches.

Week 4 Blog 2: New Patch for Java flaw on Mac OS X After a Long Time!
On May, apple give a new patch for updating java just for Mac users, but this had some java flaws in it, which lots of the hackers and security researchers start posting blogs and the data over the Internet. Also the security firm Intego, which makes security software for Macs, warned “users of a java flaw in OS X Java distribution which could allow java applets to execute malicious code.” The vulnerability also affected any other products or programs like java development kit, Sun’s JRE, and all the application that share the same core classes as Java SE and the J2SE. This was the big issue for the ones who were using the java applications every day. These days most of the websites include java features, especially applets, which could place the Mac user’s in dangerous of spyware. Therefore, for the solution at that time before the update version came out, security companies are suggesting Mac users to disable java on their browsers. As in one of the article mentioned “Security vendor SecureMac also advises Mac users to disable Java in their Web browser until Apple fixes the issue. “This vulnerability could be exploited to perform 'drive-by-downloads' commonly used as a means to infect computers with spyware, or any arbitrary command with the permissions of the executing user,” a company note on the SecureMac site reads. “All a user has to do is visit a web page hosting a malicious Java applet to be exploited.”” When programmer didn’t find any update to solve this issue, they have started to complain about that, Mac OS X security issues are ignored if the severity of the issue is not adequately demonstrated. Finally, one month later, apple release a patch for Java on OS X 10.5 and 10.4. Also Apple described that Mac OS X in update version 4 has improved “its reliability, security and compatibility for Java SE 6, J2SE 5.0 and J2SE 1.4.2 on Mac OS X 10.5.” This wasn’t the only time that Apple gave the update after a very long time and place user’s security in danger. There have been some flaw in QuickTime video player and DNS which after months these issues had been solved. Comparing all the big companies like Microsoft, Adobe, and Apples which are competing with each other, they have given dozens of patches or updates within last month. So we expect these companies to have a delay in giving the updates out but six months for this kind of vulnerability that had mentioned earlier is not acceptable.

Week 4 Blog 1: Microsoft Security Essential
Microsoft is scheduled to get launch its new free antimalware service beta version on Tuesday. This version is going to be available for US, Brazil and Israel in English. The complete version of Microsoft Security Essentials is going to be available later this year. The service will protect user’s PC on Windows XP, Vista and Windows 7. This product will be replaced with the current antivirus that Microsoft is offering called Windows Live OneCare. Currently Windows Live OneCare cost $49.99 a year for limited download on three computers but the free version of antivirus is going to be replaced with that one. Therefore it is estimated that to stop Live OneCare on June 30th. Symantec and McAfee, one of the most popular ones which are covering all the materials we have to care regarding the security of our PC and even ourselves over the Internet, are contending that Microsoft Security Essential , free product, will likely not provide the quality of technologies that they offer in the security suites. Some applications such as firewalls, data loss prevention, backup and recovery, and encryption technologies are not going to be offered on Microsoft Security Essential. I believe that this free version cannot compete with other security vendors. This version is going to be for the ones who are able to afford having antivirus and save their computers from viruses, Trojans, worms, and so on. I think if these security vendors have fear of Microsoft, they should have the fear of any other companies that they are offering free version of antivirus like AVG. I personally had tried the AVG free, and I was really happy with it. It almost provides the necessary features that I need in order to protect my computer. Also “executives at AVG, a security company with a free antivirus offering, maintained that Microsoft's impending release of Security Essentials would not threaten their core business.” Because as in the articles mentioned, AVG first tries to attract customers by offering free version. Then it starts to convince their customer that they need more than the basic version. Overall I think as soon as the complete version of Microsoft Security Essentials came out, I will start using it since I don’t have any antivirus because of some internet issues that I had when I was protecting my computer with Symantec.

Week 3 Blog 2: Microsoft Browser Offer Fails to Impress Europe
Opera, a Norwegian browser initiated the complaint on December 2007, and asked the commission to deal with Internet Explorer (IE) as they did with Media Player. Therefore, according to the complaint on Thursday, June 11th 2009, Microsoft offered to give the version out without having Internet Explorer on it. The new version for European country would be Windows 7 E version. “But the commission in a statement, dismissed the offer, saying the move could not further its goal of promoting browsers that compete with Internet Explorer.” But the most important reason for rejection of this offer is that the European commission did not want to repeat a mistake, when Microsoft ordered the software maker to sell a N version of windows which is without its media player. Commission is deciding on idea to suggest Microsoft to distribute windows with competing Web browsers installed and then allow retailers, computer makers or even customers to decide from a “ballot screen” menu which browsers to install. The ballot screen options, or in other words the web browsers candidates are Mozilla’s Firefox, Apple’s Safari, Google’s Chrome, and Opera beside Internet Explorer.
As in the other article Microsoft mentioned, it needs start telling OEMs by the end of this week what exactly they expect in Windows 7, so they can begin the software engineering work necessary to have their windows 7 PCs available in stores on that day. Microsoft is moving forward with a collaborative tone: "We will continue to discuss browser issues and other matters with the Commission. But even as the Commission processes continue, we know we need to have a clear plan in place to address the “bundling” issue in Europe because, at the end of the day, the obligation to comply with European competition law belongs to Microsoft alone".
I agree with the complaint that Opera made on this situation. But there is a case if a customer receives the PC without any web browser installed, and he doesn’t have enough knowledge to use the computer. Then how this problem is going to be solved for him. I as one that I almost tried every web browsers, I personally more comfortable to use IE and Google chrome than the others. Even it was very hard for me to choose which browser to use. I prefer to have IE already installed than the others. Also the E version is not going to work as the commission mentioned too in case of selling the complete version in parallel.

Week 3 Blog 1: Wireless Power Harvesting for Cell Phones
Nokia is developing technology that could draw enough power from ambient radio waves, so we don't need to charge the battery. Ambient electromagnetic radiation, the sort of stuff that is given off by our WI-FI transmitters, Mobile phone antenna and even giant TV mast, could be harnessed and converted into sufficient electrical power to top our battery simply as we walk. The Nokia devices will work as the same principle as a crystal radio set by converting electromagnetic waves into an electrical signal. The way that crystal set radio works, it uses no power. The circuit consists of an inductor (called a coil), a variable capacitor, a germanium diode, a filtering capacitor and finally very high impedance headphones. Rouvala, a researcher from the Nokia Research Centre, in Cambridge, U.K, said that the prototype needs to harvest 50 milliwatts of power in order to charge the phone with power. With today's technology, the prototype is able to harvest only three to five milliwatts. Therefore, as it mentioned in the article, Nokia needs a wideband receiver to capture signals from between 500 megahertz and 10 gigahertz; a range to cover many different radio signals. As it mentioned other universities are working on different projects related to use the power that the device is capable of harvesting from ambient RF.
"Earlier this year, Joshua Smith at Intel and Alanson Sample at the University of Washington, in Seattle, developed a temperature-and-humidity sensor that draws its power from the signal emitted by a 1.0-megawatt TV antenna 4.1 kilometers away. However, this only involved generating 60 microwatts.
Smith says that 50 milliwatts could require around 1,000 strong signals and that an antenna capable of picking up such a wide range of frequencies would cause efficiency losses along the way." It has been mentioned that it is possible to see this capability in the cell phones within three to four years. According to the other article this technology is not going to be used only for Nokia but it should be used for any other devices which are capable of working with the less power. Nokia plans to use this technology in combination of other energy-harvesting approaches like solar cells that could be embedded in the outside case of handset.
This technology, harvesting ambient electromagnetic radiation and converting to electrical power, would be the best one for most of the cell phone users. I personally will get the phone that has this technology so I wouldn't need to carry the cell phone charger with myself, since sometimes I will forget to charge it. But there is a question regarding that, is this technology depends on the atmosphere condition or not? Some researchers on the ambient radiation, in Hong Kong, agreed that the radiation level will be changed depends on the weather condition. According to the rain, wind, tropical cyclone, and even seasonal changes make changes to the radiation level. Therefore, I believe it's not going to work perfectly for all over the world.

Week 2 Blog 3: Is Palm Pre Taking Over iPhone?
In the new era, there sexist a lot of hand held computers super smart touch screen computers, which iPhone is the king. On Saturday June 6, 2009, the new smart phone called Palm Pre came out which is a touch screen phone. This article is giving the advantages and disadvantages of this phone in compare to the existence smart phones especially iPhone. Palm gives out this phone with the new operating system called webOS which in contrast with other smart phones like “iPhone, Google’s new Android phone operating system, and the modern BlackBerry models from Research in Motion, it does more than making phone call or browsing internet. It’s like a platform like a PC, capable of running a wide variety of sophisticated third party programs, or apps, from social networking gateways to games to business tools.” This phone has a Wi-Fi capability. Also, it is in the same range of rice like the other smart phones $200. One of the biggest advantages of Palm Pre over iPhone is having the physical keyboard. I believe that attract more customers who are iPhone’s fan to it. One of the reasons that I as a smart phone user didn’t chose iPhone, is having the virtual-keyboard screen. “The Pre also features an elegant new take on the multitouch user interface. It uses a card metaphor. Each program, or window, appears in virtual cards on the screen, and you can flip through them and zoom in to use one, or quickly dismiss one by flicking it up and off the screen. An individual email, or contact, can occupy its own card. And, unlike on the iPhone, the Pre can simultaneously run any programs you choose.” The other big feature, it automatically can merge similar contact from disparate sources, like Google and Face book, same thing applies for the calendars. Also, with the wireless capability that it has, it can automatically sync in air with Google’s calendar or Microsoft exchange. Pre features a wireless backup service, which stores copy of data on a server plan, in case if you need to recover them. Also in the other article mentioned that Pre makes use of a Low-Temperature Polysilicon (LTPS) LCD display. Another interesting thing about this phone is that developer designed it so makes iTunes recognize it as the iPhone or iPod. But when it comes for using the Apps store, and downloading the application; it is possible to get problem like losing everything and you’ll be force to recover the phone in order to use Wi-Fi and the applications. One of the reasons is that developers are still working on that; also, they already mentioned that it is not complete. By considering the advantages and disadvantages of this phone over other smart phones, I will look for this new phone to buy it after they fix the issues they have now with downloading and so on. But the final decision depends on how new iPhone is going to be presented. Also because I am a little bit biased toward Microsoft, I have to wait for Windows mobile 7.

Week 1 Blog 3: Attraction Of Windows 7 To Netbook Users
Mr. LeBlanc, a Windows communications manager at Microsoft, mentioned that all editions of Windows 7 have been designed to run on the broadest range of hardware. Microsoft Beta have to test all editions on computers with the following characteristics 1 GHz processor, 1 GB of system memory, 16 GB of available disk space, Support for DX9 graphics, DVD-R/W Drive, Internet access. This shows Windows 7 operating system can be used on the very basic machines as same as Netbooks. But as Mr. LeBlanc said starter edition has only the subset of higher level editions. The list of things that Windows 7 Starter does not include has been mentioned in the article. In case of I as a buyer of operating system will not buy starter edition because it cannot support the switch users without having the user to log off.
In conclusion, I believe others operating system which were being used in the Netbooks can be replaced by Windows 7 but not the starter edition because it still have some problems that users will concern.

Week 1, Blog 1 : Restriction of Windows Live Messanger On The Embargoed Countries
Toward the issues of blocking usage of messenger for embargoed countries, one solution is mentioned in other article. User can change the home location which is located under registration information to the new country or region that is not under the name of those five countries. Because Microsoft make decisions based on the profile information opposed to IP addresses. If this is the case blocking Messenger from Microsoft wouldn’t work well.
