Artifical intelligence as a branch of computer science which studies the behavior of intelligent automation, and artificial intelligence based on teorika and principles - principles that includes the data structure or algorithm commonly used in knowledge representation.
Algorithm that is required for establishment of such knowledge is the techniques of ordinary language is handled by artificial intelligence, including the
1. Problem solving in general
2. Understanding language
3. Solution EXPERT PROBLEM? EXPERT SYSTEM
4. Proving a _ THEOREM THEOREM
Step - turing test steps in AI →
1. Achieving behavior of artificial intelligence that has been known for a number of specific questions

Limitations of them is expert system expert system →
1. limited flexibility
2. unutk inability to do / provide in-depth explanation
3. difficulty in proving a problem
4. difficulties in capturing the knowledge of the issue - the issue at hand.
The difference with the standard computer programs of artificial intelligence
Computer standards => can only solve the problem - problems that have been in the program specifically.
Artificial intelligence => a way to simplify the program, artificial intelligence that can mimic the learning process so that the information sought can be absorbed and used for the future.

Hero Changes

Alchemist
- Reworked Unstable Concoction



    Razzil brews up an unstable concoction that he can throw at an enemy hero, to stun and deal damage. Once Razzil starts brewing, he can continue for up to 5 seconds. Each second of brewing will increase the potency of the concoction and make Razzil more red. After the 5 seconds, there is a small buffer window. If Razzil does not throw the concoction soon after it will blow up and Razzil himself will suffer as if he was hit by the concoction. Concoction can blow up mid air if fired too late.

    Charge Duration: up to 5 seconds
    Buffer Duration: 1.5
    Damage: Up to 150/200/250/300 (Physical damage type)

Scroll of Town Portal
- Reworked mechanics

- The casting time system for scroll teleports are now dynamic.
Whenever a hero teleports to an area, it causes any other teleports to that area to be delayed with extra time based on the number of heroes that teleported or are teleporting there. Each teleport leaves has memory lasts about 20 seconds for that location.

This does not affect teleports to the fountain area (it accounts for rough areas around shop area as well).

Example: First hero teleports to his tower, he takes the usual 3 seconds casting time. Then lets say the 3 other heroes teleport right after. The second one that telports after the original has a 5 second teleport time. Then 6 seconds, 7, etc.

- Teleport location effect no longer lies to the enemies about the landing spot

- Enemies now see the colors of the teleporting heroes

- Increases max range on where you can choose teleport near a building from 350 to 525

Smart Telecom has finally launched its new network that is smart rev.b EVDO which is the fastest network in Asia Pacific. This new network has an 3x speed than the speed of rev.b. but it is only new network in regional trials in Bali, and if the new network is running smoothly it will be extended to an area that has mendadpatkan area of smart service.

Smart Destination network upgrade nothing to enhance the quality of data services in CDMA realm. Previously, Smart operating in 1900 MHz frequency band, relying on EVDO Rev A network is spread across five cities, Greater Jakarta, Surabaya, Bandung, Bali, and Yogyakarta.

"The total until the end of the year, Rev A already exists in 32 cities. Starting from Sumatra to Makassar. However, for the Rev. B while a new trial in Bali alone," continued Ruby.

Smart network trials that took place in Bali using two channels available in 48 base transceiver stations (BTS) of his, which uses Qualcomm's technology and network devices its base station's ZTE.

EVDO Rev B is a Rev A technology development that could provide faster speed, ie up to 9.3 Mbps for downloads and 5.4 Mbps for upload. While EVDO Rev A, the velocity is only up to 3.1 Mbps for downloads and 1.8 Mbps for upload.a

EVDO is a high-speed access services on CDMA networks, can be said as its 3G CDMA. Unlike the GSM which has 3G coverage is very broad, EVDO network has a range much smaller than the 3G GSM. To be able memeberikan EVDO service operators must build EVDO base stations in places you want to reach. In Indonesia there are only 2 operators to provide EVDO service is the MOBI and SMART. Unfortunately still some areas that can enjoy this service. Mobi new operators have the EVDO network in the area and also jabodetabek bandung, the SMART whereas more advanced level than MOBI than 2 area formerly called smart EVDO Service also has presence in the city of Yogyakarta, Surabaya and Bali.
Now to the point just following the smart EVDO coverage map in the region of Yogyakarta.

CLIENT-SERVER ARCHITECTURE

Diposting oleh Raden Mas Nureko Kustiarno Wibowo 0 komentar

Client is a process that actively request service from another process. The server is a process that will passively wait for service requests from other processes, then execute the request, and provide responses to the request.


A. STAND ALONE (Tier 1)





In this architecture all the processing done on the mainframe. Application code, data and all system components are placed and executed on the host. Although the client computer used to access the mainframe, no padamesin processing this happens, and because they "dump-client" or "dump-terminal". Type model, where all processing occurs centrally, known as host-based. Glance can be found fault with this model. There was a problem in host-based computing: First, all processing occurs on a single machine, so that more users are accessing the host, become increasingly overwhelmed.






• Excess Stand Alone (Tier 1)
Installation of more modest and uncomplicated use karna only 1 host.?

• Lack Stand Alone (Tier 1)
Performance will be slow if all users access at the same time.?
Without the network can not access other computers?
Risk encoding not happen tersetruktur?

B. TWO-TIER

Client / Server is also a Tier Two because this architecture has only two levels, one as a client and another as a server. This architecture enables applications on client computers interact with the server through the network. And applications in place on the client computer and the machine, then run the database on the server. And applications in use by the client sends a request to the server and then shipped back to the client.




• Excess Two-Tier
reduce the processing burden from a central computer to the client computer.? This means that more and more users get on the application client / server, file server performance will not decrease rapidly
It can change the business logic with logic persentation?

• Lack of Two-Tier
Lack of scalability?
A database connection is maintained?
There is no code keterbaharuan?
There is no mid-level to handle security and transaction?
to design and implement protocols?
to design and implement a reliable data storage?

C. three-tier
Model three-tier or multi-tier developed to address limitations in the architecture of client / server. In this model, distributed processing in the three layers (or more if applied multitier architecture). The third layer in this architecture each adding specific functionality. Namely:
• Service presentation (the clients)
• business services (intermediate level)
• Service data (data source level)
Services presentation or user interface logic is placed on the client machine. Business logic out of the client code and placed in the middle level. Data services layer contains the server.
The concept of three-tier model is a model that divides functionality into layers, aplikasiaplikasi get scalability, keterbaharuan, and security.







Excess three-tier?
? Connection database can be in-pool and then shared by several users, which will greatly reduce the costs associated with per-user licensing.
Organization has a database of independent, because the data layer is written using standard SQL platform is free.? The company is not tied to vendor-specific stored procedures.
application layer written in the third or fourth generation standard, which has used programmers from the company.?


• Lack of three-tier
Requires lord network bandwidth.?
relational mapping difficult objec?

D. N-tier

Multi-Tier Architecture is a method very similar to Tier Three. The difference, in Multi Tier is made clear the UI (User Interface) and Processing.Yang Data architecture is distinguished by the Business Logic Server. Database Server and Bussines Logic Server is part of Data Processing, and Application Server and Client / Terminal is part of the UI.







• Excess N-tier

The relationship between application layer, middle layer and back-end layer becomes increasingly more clear and unambiguous?
It is also safer security dibandingankan concept of client / server or desktop?
In the event of application development, using concepts like this become much more flexible?
We can provide a rule-the rule is clear to any process tha?t will be used by the application layer

• Lack of three-tier
?It is not efisient
likely to occur bugs?Karna too complexes
It is difficult in sharing the burden.?

What is Web 2.0

Web 2.0
Web 2.0, is a term first coined by O'Reilly Media in 2003, and was popularized in the first Web 2.0 conference in 2004, and refers to the generation that is perceived as the second generation of web-based services such as social networking sites, wikis, tools communication, and folksonomi that emphasize online collaboration and sharing between users. O'Reilly Media, a collaboration with MediaLive International, uses this term as a title for a series of conferences, and since 2004 some developers and marketers have adopted this phrase.
Although this term seems to indicate a new version rather than the web, this term does not refer to an update to the technical specifications of the World Wide Web, but rather, how the system developers in the web platform. Referring to Tim Oreilly, the term Web 2.0 is defined as follows:
"Web 2.0 is a business revolution in the computer industry caused by the movement to the Internet as platform, and an attempt to understand the rules for success on that platform."
And the development of web 2.0 is more emphasis on changes in the present way of thinking and viewing content on a website. In the development of Web 2.0 is applied as a form of presentation of web pages is of a general desktop programs such as Windows. The functions of the application has to be like a desktop, such as drag and drop, auto-complete, and other functions. Web 2.0 applications are presented in full in a web browser without the need for advanced technology devices from the user.
Examples of the difference between Web 1.0 and Web 2.0 is web 1.0 if the visitors can only read the existing content on the web, so this type of website will look like a bulletin board on the web, and very boring. is not it, if the Web 2.0 in penguna give freedom to make comments on the content, this web type more she loved by the people we are able to interact karna by admin or other web visitors
remains one of the Web 1.0 is the Britannica Online is one of the most comprehensive free website in cyberspace, but the editorial content on the web is held by the parties in the Britannica itself. And we can not comment on or change anything contained in the website, by karna is likely contents contained in this website is not up to date. we can use the information tiak long karna information is subject to change at any time. And the website has only one language is English language so the people who can not speak English should first menterjemahkanya in order to understand.
Unlike wikipedia, the free-style web 2.0 which is now known, and many more students seeking jobs and students around the world. On wikipedia all visitors of this website can contribute, correct, and complete all the content in it, therefore this website will always be up to date because of the contribution provided by web site visitors. And wikipedia has many language versions of the entire world, so who wrote directly read with their language in tau without the hassle for his first menterjemahkanya. This free application that can even be a good learning tool.

70 tips and trick how to use windows 7

Diposting oleh Raden Mas Nureko Kustiarno Wibowo 0 komentar


windows windows 7 is a recently been launched by microsft. since these new windows, and also because we are accustomed to wearing long-windows so sometimes we feel confused. by karna I tried to find some tips and trick windows 7. and there was a lot, so I took an article from the softsailor.com memberitaukan about 70 tips and tricks like using windows where 7.

1. PC Safeguard
I rarely let anyone use my PC because I’m afraid he will mess it up, but it seems Microsoft has been thinking at me and came with a solution. The PC Safeguard doesn’t let anyone mess your PC settings, because after the user logs off, the configurations are reset back to normal. Of course it will not restore the configurations changed by you, but only the ones done by other users you define.[ad#social]
To use PC Safeguard, go to Control Panel -> User Accounts and create a new account, then select “Set Up Pc Safeguard” and switch it on. Then you can stay relaxed when others use your computer, because you won’t find anything changed, including configurations, downloaded software, installed programs.
2. Screen Calibration
Fortunately, Windows 7 comes with a display calibration wizard that lets you set up the screen brightness properly, so you won’t have any problems viewing photos or text. The problem was that on one PC a photo could look sharp and bright and on another it looks awful. Now the problem can be fixed by pressing the Win key and then typing “DCCW”.
3. AppLocker
If you are usually sharing your computer with someone else, then you might want to restrict their access to your applications, files or documents. Using the AppLocker tool, you have a few options to do this by blocking other users to access Executables, Windows Installers, Scripts, a specific publisher or path. You can simply do this by pressing the Windows key then typing Gpedit.msc. Then go to Computer Navigation -> Windows Settings -> Security Settings -> Application Control Policies -> AppLocker. Right click on one of the options ( Executables, Installers, or Script ) and create a new rule. That should save you from a lot of headaches.
4. Burn Images
We all had trouble with image burning in Windows, because it couldn’t do it itself, a standalone software being needed. With Windows 7 this will not be a problem anymore. All you have to do is double-click the ISO image and burn it on the CD or DVD that’s inserted in the drive.
5. Display Empty Removable Drives
Windows 7 will not show empty drives by default, so if you connect an empty drive to your PC, don’t worry, just go to Tools -> Folder Options -> View and uncheck “Hide empty drives in the computer folder”. This doesn’t seem like a good idea and it should not be default setting, because it will be hard for inexperienced users to figure it out. I bet a lot of users will return their newly bought drive thinking it’s broken.
6. Dock The Current Windows To The Left Side Of The Screen
This new feature seems useful because sometimes it’s disturbing that windows seems to float like crazy on the screen and it’s hard to attach them to one side of it. Now this can easily be done using a keyboard shortcut. Press the Windows key + Left key to dock it to the left side of the screen.

Right click on the desktop then go to Personalize -> Desktop Background and hold the CTRL key while choosing the images. Then you can choose the time intervals between images and opt to display them randomly or in a row.
11. Make The Taskbar Smaller
If you feel like the taskbar is using too much of your screen space, you can choose to make the icons smaller. To do this, right-click on the Start button, then go to Properties -> Taskbar and set it to “Use small icons”
12. Combine Taskbar Icons
When you have more windows or applications opened, the taskbar’s space might not be enough for them all, so you need to combine them, just like you would in Windows XP or Vista. To do this, right-click the Start button, then go to Properties -> Taskbar and check “Combine when taskbar is full”.
13. Multi-threaded File Copy
If you are a more advanced user, you’ve heard already about Robocopy. Now it’s included in Windows 7 and lets you perform multi-threaded copies from the command line. You can choose the number of threads like this “/MT[:n], which can be from 1 to 128.
14. Maximize Or Restore The Foreground Window
Press Windows Key + Up Key.
15. Minimize The Active Window
Press Windows Key + Down Key

SQL Optimization

 can be done in various ways, with the understanding of database performance tuning and best practices from various sources, you can have a strong fundamental in optimizing database performance.
Some of the techniques and methods may require special treatment different, depending on the database you use.
For example, performance improvements can be done from the administrative database like configu ration file and self-service or security updatean pack, which of course each database has its own uniqueness and techniques.
Then, with consideration of compatibility, is there any optimization that can be done in general?
There are a set of methods and techniques commonly applied when working with RDBMS (Relational Database Management System), may not be all that you can implement because the environment is highly dependent on each application, but at least you can use it as a guide and reference to establish a system best accordance with the conditions encountered.
Optimization via the SQL command also plays a no less important. The core of the SQL itself is a command to perform retrieval (retrieval), the addition (insertion), modification (updating), and elimination (deletion) of data, coupled with support functions of administration and database management.
SQL itself is a standard programming language or to the RDBMS. Although called a language, maybe a little awkward when we refer to the SQL programming language, more familiar when the sounds are programming C, Visual Basic, Java, Delphi, and so on.
The languages of the latter included in the imperative programming, is a language easily shaped core instructions. Meanwhile, the SQL included in declarative programming, which is more form sentences or statements.
In its development, SQL divided again in a variety of extensions that gave birth to a variety of titles such as SQL / PSM (Persistent Stored Modules) is a standard ANSI / ISO, T-SQL (Transact-SQL) of Microsoft and Sybase, PL / SQL (PL is stands for Procedural Language) which is used by Oracle, which later developed more into PL / pgsql is used PostgreSQL.
Quite confusing, is not it? Fortunately the concept and basic elements such as the SQL statement, query, expression, or continue to apply the general clause on every SQL extension.
We both ends meet theoretical discussion here, here are some simple optimizations that you can do, to at least fix or prevent problems, and improve the performance of your RDBMS.
Index
The first optimization that we discussed was the problem index, of course you know that the index can increase the search speed in the desired record. However, you must be quite selective in choosing a field that needs to index, since not all fields need it.
Proverbial read books, or scan the search process will read from beginning to end of the page. In the on-field index, search index scan is done, or read on the index, not directly on the table in question.
Meanwhile, direct searches made by reading the record after record on the table is called a table scan.
Is index scan is always faster than the table scan? It did not also, table scan can be run faster when accessing the record in a relatively small amount, or when the application does require reading the entire table.
Instead of accessing a great record in a particular field, index scan can reduce the reading operation I / O so that not infrequently result in faster performance.
As a rule, you can specify the index on the field that is often used, for example, fields that are often accessed by the WHERE clause, JOIN, ORDER BY, GROUP BY.
Defining Data Types
Data type is a problem tricky. In terms of capacity, the type of data that are too small or otherwise too large for a field, can cause a ticking time bomb that caused the problem in line with the rapid increase of data each day.
Determining the proper data type requires precision and good analysis. For example, we need to know when we use the data type char or varchar.
Both contain characters, the difference between char provides fixed storage size (fi xed-length), while VARCHAR provides storage size in accordance with the contents of data (variable-length).
General rule is to use the char data type if fi Eld is intended for the data with a consistent length. For example zip code, month consisting of two digits (01 to 12), and so on. Int used if the data is stored to a variable length, or use varchar (max) when its size exceeds 8000 bytes.
Do not Allow Allow Null
If possible, reduce the use of fields that allow null values. Instead, you can provide default values in the field.
Null values sometimes overlap in interpretation can lead programmers and programming logic errors. In addition, eating a null-byte field that adds an additional burden on queries that access it.
Easy Read Query
Because SQL is a declarative language, it is not surprising if you make a query form nan sentence length, although perhaps only for the purpose of displaying a single field!
Do not let your query hard to read and understand, unless you're going to make anyone dizzy seeing your query. Long queries written in a clear 1baris modification would complicate cation and understanding, would be far better if you write a query in a format that is easily digested.
The selection of large and small letters can also facilitate the reading, for example by consistently write SQL keywords in capital letters, and add comments if necessary.
Avoid SELECT *
Select keywords that may be the most frequently used, because the optimization of the SELECT command is likely to improve overall application performance. \
SELECT * is used to query all the fields contained in a table, but if you only want to process a certain field, then you should write down the field that wants to access it, so that your query becomes SELECT field1, field2, field3 and so on (never mind the source code which grew longer!). This will reduce the network traffic load and lock on the table, especially if the table has many fields and large.
Limit the ORDER BY
Use the ORDER BY to sort the data function, it has the burden of the consequences of adding the query, because it will add one more process, ie sort process.
Therefore, use ORDER BY only if absolutely needed by your application.
Or if possible, you can perform sorting on the client side and not on the server side. For example, by accommodating the first data grid components and perform sorting on the grid according to user needs.
Subquery Or JOIN
Sometimes a single instruction can be written in the form of subquery or JOIN command, you are advised to prioritize the use of JOIN because in the general case will result in faster performance.
However, the query processing is an art, it is always possible subquery to work faster than JOIN, for example in conditions of use
JOIN is too much, or the logic of the query that has not been optimal.

YouTube, Vimeo Try Out HTML 5.0 Video

YouTube this week announced support for a prototype player that uses HTML 5, and Vimeo has jumped in as well.

The prototype YouTube player is available here, while Vimeo's new palyer can be enabled by clicking the "switch to HTML5 player" link below its videos. Both players can only use the Chrome, Safari, and the ChromeFrame plugin for Internet Explorer.

HTML 5.0 received its coming-out party at the Google I/O conference in May 2009; in December, Google said that it would eventually drop its Google Gears offline utility in favor of HTML 5.0.

For video, HTML 5.0's chief advantage is that it includes video as a supported tag. According to proponents, this allows simplified coding, and the ability to jump in and out of video streams at various places without the need for buffering.

As such, however, the first uses of HTML 5.0 are little more than prototypes. "Our support for HTML5 is an early experiment, and there are some limitations," YouTube said in a blog post authored by Kevin Carle and Chris Zacharias, both engineers for the company. "HTML5 on YouTube doesn't support videos with ads, captions, or annotations and it requires a browser that supports both the video tag and h.264 encoded video (currently that means Chrome, Safari, and ChromeFrame on Internet Explorer). We will be expanding the capabilities of the player in the future, so get ready for new and improved versions in the months to come."

Vimeo's Brad Dougherty also noted that the new player won't work on all Vimeo videos - although about 90 percent are supported - and the HTML 5.0 player is only enabled on videos viewed directly from the Vimeo site. As of Thursday, the Vimeo HTML 5.0 player also could not play videos back in full-screen mode.

"The simple fact is right now h264 allows us the most flexibility to display on many devices and many players with the same file,' Dougherty said. "When that changes, so will we."
