TV Mobili : Free Media Server For Windows , MAC and Linux

Media Server is the server to broadcast media content like music, movie, picture whether across the internet world wide or just in your local area network.

in old days, we used to built the entire PC including setting the network solution just for home media server let alone the OS itself. but now, with the technology called UPNP (Universal Plug N Play), you can setup media server in a minute.

today, i will instruct you on how you wanna do it.

Hardware Requirement :


  • Cable RJ45 (depend on your network architecture).
  • Router
  • An old Computer that wanna TV Mobili Server.
  • A laptop or computer to test the TVMobili Server.



Software Requirement: 


You need to install this software. Below are the instruction phased by phased using images.







After install this software make sure to take note tv mobili url!. This is important because you need to setup its broadcasting content. for example what folder, should or should not been broadcast to the local area network. 

Access to TVMobili

  • Open any browser. etc mozilla, chrome, safari, opera, firefox and ie.
  • Type in tv mobili url.

"In case if you dont find the TVMobili url, here i will provide for you. http://localhost:30888" 

Thats it. You have setup your own free media server based on UPNP network. This is the end of TV Mobili Setup Part. Next, we gonna review what inside the TVMobili Web apps can bring us.

Anyone who dont understand or have  questions please give a comment down below. thank you.

Networking : What We Must Know

Network nowadays in essential in many aspects of business, social and educational. The Network is so called connection, between men, between machine nor computer. By creating a network, someone or something will be far more productive rather than single, standalone object. 

Today, we talked about computer network. Same as before, a connection between 2 or more object to achieve multiple objective. This "object" refers to computers. Computer alone can do many things but it is depends on how the user uses it. But by network, some aspect in computer a far more fascinating that those simple painting. 

Every thing needs a plan. there is no excluding in computer network. When there is plan, there is architecture.

Architecture


To create an architecture of computer network, someone needs to calculate several things before move the environment to the desired architecture. 

First of all, Scalability issue. From time to time the company will expand and we need to add new nodes. The problem is reside in the hardware. How many port/patch panel/modular jack needed to complete this task?

"scalability is the ability of a system, network, or process, to handle a growing amount of work in a capable manner or its ability to be enlarged to accommodate that growth. - wikipedia"

Lets say, the company have 5 computer right now. But the business is expanding. They need to use accountant department and centralize server. If you only buy hardware that only support 5 computers. The company surely have a hard time in budgeting the company revenue. 

Why It Counts? 

Based on the number of nodes and analytically increment over years, the major problem about connection between nodes is Reliability of the network itself. Reliability here means the connection are stable and smooth.

Reliability is a protocol to ensure the network stable and ready to use to send data over the network. For example, data request when certain packet are drop or damage due to the transmission over the line. Other than that, it also describe as reduce down time network which is mean that the network never disconnect its own client to satisfy other priority. 

"Realibility of a network often been tested by data transmitting. the way their doing the test is to stress the network with high volume of data transmitting until it fail."

Work Load

When things became real demanding and real-time, the workload will become very important. The workload in network is how many concurrent connection made by end user to server. What the server serve to satisfying user needs? how big the data that being transmitted throughout the line? 

At the end, workload depends on how users utilize that network. if the network is use for p2p downloading, the traffic will be sky high because the line receive larger data volume simultaneously. If in the network have high users traffic, i mean u need to change several things to be automaton, for example a server. a server can serve up to 300 users in one SME company. 



Thats all for today. see ya. if any question, pls comment below.

How to do Defragmentation on PC

Disk Defragmenter is Maintenance Disk keeper . The version that is included with Windows XP and later provides limited functionality in maintaining disk performance by defragmenting volumes that use the FAT, FAT32, or NTFS file system. 

Some of the computer will be very slow when used for a long time without defrag the HDD. This occur because the system files, source files are being fragmented in several location through out the HDD. Thats why computer will be slow in order to search that particular files.


For Windows XP



Method 1: Use the Local Disk Properties
  • Open My Computer.
  • Right-click the local disk volume that you want to defragment, and then click Properties.
  • On the Tools tab, click Defragment Now.
  • Click Defragment.


Method 2: Use Defragment menu in Start Button
  • Click Start Button.
  • Click All Program.
  • Click Accessories Menu.
  • Click System Tools.
  • Click Disk Defragmenter.
  • Click the volume that you want to defragment, and then click Defragment.

For windows 7 : 


it is the same as windows xp but Microsoft make it very simple to search this defragment 
menu.

Method 1: Using Search in the Start Menu
  • Click Start Menu
  • Click Search Textbox
  • Type "Defrag" without the quotes.
  • Select top of the list.
  • Click the volume that you want to defragment, and then click Defragment.

For more easier, i put a software that do your bidding. 

Free Dowload Software.

Trash Can Invention : JAPAN

world of technologies bring us further a head with machine where the machine can understand human language. But how we design in to be in simplest daily task like Trash Can? How can you toss it like a boss and that trash can moving on its own? here is the video on how they do it. Japan, you have my respect on environmental upgrading..


 i think i wanna do some too. master my engineering course. hehehe

DIY : CCTV For Home (Part ONE)

Getting The Items Ready


Many people thinks that buying CCTV system is expensive and waste for only home environment. it is not true. from what i was thinking is, CCTV system is a must to prevent any crime on your property whether property theft, accident, and etc.

Today, i gonna tell you that under 200 bucks can get u CCTV system to your house. The item that we need is will be put in below list:

1. ANY IP camera. Come in 2 choices whether to used Wifi or Cable.
2. A SERVER. Can used old pc. the one which collecting dust around the corner. Must Have OS at least XP
3. ANY Router. the connection between server and IP camera. need to port forwarding the CCTV port.
4. ANY RJ45 Cable. Connection between Router to SERVER.
5. An Internet Connection. This one is OPTIONAL.

Overview

Camera

For this experiment, i choose Dlink DCS-920 IP Camera for home surveillance system. This camera come in 2 option whether to use Wifi or cable in a box. so its handy when to configure to Server or Router. This camera also have motion detection region or this system called Smart Recording. Smart Recording reduce your hard disk consumption because it only record when there are movements detect on the camera including shadows. To configure this thing is not very hard. Just it need to be configure using Cable first before you can use the Wifi. The pixel of this camera is up to 640 X 480 HQVGA which means the pixel are crystal clear in range 10m ~ 30m.

Router 

Probably you should buy router that come with Wifi Antenna. I said so because we need to design SmartHome Surveillance system. So less cable means more secure. Thief doesn't know where you put your server is, what cable should they cut. The hardest part for none-IT people in this is every router comes with different menu when come to port forwarding. for example, for Dlink DIR-600, the port forwarding fall under Advanced Menu. I personally don't know what other Router port forwarding categories is.

Server

Many people think if wanna server, u need to buy it. Why not you build one? Okay, take old pc that you don't use anymore. Clean it up. After cleaning it, please install at least Windows XP. Then, if you used Dlink IP Camera, they should provide you with CD Installation. Install the CD content and don't forget to configure IP for the camera and server at this server! many people done mistake that he/she thinks the CD is for camera's driver but it is not. The CD is Installation Program For The Server. After installing and configuring it, it become a server. This part is done.

Cable RJ45

Why we used cable? because the connection from pc to router need to be establish using LAN Cable or we called it RJ45. You also can convert the cable by installing the USB Wifi Dongle at server. its the same thing.
Just remember. Only Camera is using Wifi. because we need it to be secure.

Internet Connection

This is an optional where you can view your CCTV Live Streaming from internet to your house. If you want to do it, first you need to sign up at dyndns.com and register your server public IP. Then from there, you will need to setup your server to be able to play live streaming. I will explain in part 2 later.


So guys, are you with me? if you not understand any part of this section, please kindly inform me by leaving your comment or email me..

Part 2 in near future...

No Sql Approach

No SQL, exactly as its name. its the database that dont use the SQL syntax. the method apply when the database need to retrieve huge data in one single output.

the specification to use no sql is, there are not booking system, they are real time system that based on notification... when talked about notification. in your mind is Facebook. thats correct!!

Facebook used NoSQL database to retrieve huge comment, picture, sound, music and file system for the user. notification are included.

so what exactly NoSQL? the database that dont depend on relational object of one system.

  1. its a database that dont run sql
  2. its a coding that request huge amount of data from server
  3. its a server that put all the data together thus eliminated the traditional database

Who used it this days? 

  1. facebook
  2. twitter
  3. google
  4. yahoo
  5. amazon 
It is many NoSQL database out there? the answer is YES. not single NoSQL can done so many things at once. here is the list

  • Column Families
  • Document Store
  • Turple Store / Key-Value Store
  • Graph
  • Multimodel Database
  • Object Database
  • Grid and Cloud Database Solution
  • XML Database
  • MultiDimensional Database
  • MultiValue Database

so u need to know how to retrieve this database value based on what attributed you need to called. for myself, i need to learn more on how to cross platform the xml to the api NoSQL server..

see ya soon

Build our own Data Center


Every technician dream that our home filled with bunch of techies stuff and that carry incredible, out of mind blowing task to entire home. such as Home PBX, Wireless bridge, or Broadcasting Movies from your home. but today, i will guide you to what is SAN and what relation between SAN and Data Center...

Data Center is a center that govern all telecommunication, network, security and even data storage in one single center. The meaning of center here is it can be clusters, merging together, stacking each other, multiple network monitoring.

NAS is Network Attached Storage. Its a independence device that have built in network card to be plugin directly to the router or switch at our home. it have webserver built in to manage its own IP address. so user can upload store the file remotely. difference between SAN and NAS is, in NAS, U NEED TO KNOW THE IP ADRESS OF THE DEVICE. Meanwhile, SAN, U NEED TO INSTALL INITIATOR IN ORDER TO MAKE IT NATIVE LOCAL HARD DRIVE IN YOUR COMPUTER.

SAN is Storage Attached Network that provide you storage for iSCSI (Internet Small Computer System Interface) in LAN (Local Area Network) environment networking. typically mean that others computer storage/hard disk/partition can be like native local storage inside your computer if its in the same network as yours computer even the partition/hard disk are at another server..

illustration are best way to describe this..

This is the physical topology how SAN being put in a network.
This is Logical Topology how SAN share its storage..


How to build your own SAN? let me teach you how....

SAN requirement is :

1) SAN server can used old computer. depend on the requirement of the system.
2) FreeNAS software <---- this is a good linux software for setup SAN.
3) Router that support GigaByte LAN
4) RJ 45 depending on how long/many connection in your house..
5) Internet Connectivity to youtube how to setup FreeNAS 8.

That's all..... easy installation....


we will discuss about this when i have demand to build a SAN...
