download for today

firefox 3.6 beta already out and you can test to use it.you can download it here
actually I like firefox and it’s a good browser with many improvements. but in this beta there are some problem with the addon compatibility,so if you use addons a lot in firefox then I suggest you use a stable version and not a beta.
and also AVG just released AVG 9.0 antivirus for free. download it here
actually I did not use avg for a little while because it wants it user to buy avg.and to tell you the truth this is the thing that I hated.that’s why I switch to use avira antivirus which is a free edition.but I do hope this AVG antivirus did not charge for money anymore or else they’ll lose many customer then.

search engine

did you know how google works? google uses crawler to travels through the links of web and jumping from one web to another when it found a link.  so every links point to another link and so on. by using this method, the crawler able to travel the whole web, parse the page document and cache it and also make the index of the whole web. the indexing process of the web by google make it easy for us to search for document in google. but there are some webs that cannot be indexed by google and therefore you cannot search for it. this site that’s not google friendly is site that uses login credentials such as facebook and other similar website. and also google cannot index webpage that uses flash, because there are no known method of how to index webpage that uses flash as a whole. and also website that often uses dropdown menu may not be indexed efficiently. we should put links written in html form in webpage for google to be able to index properly and can be found when one search for the document. through time google web crawler has improve itself and can update the indexed of a webpage in a minute in google database.

there are 3 things that a search engine must do first

1. stoplist

stoplist is the list of common word, such as the,a,an,etc. this word sometime is not indexed and therefore when you search for it,it will show that your query is too common

2. stemming

stemming is the process of shortening the word. such as shooting will be shoot, solution will be solute and so on. this is necessary so the search engine will know what it’s search for and can made an efficient indexing

3. thesaurus

thesaurus is the synonym for the word. therefore when you search for cardiac arrest then heart attack will show up in the search result. it is necessary for efficient indexing

so the above rule applies to most search engine.

testing koneksi ke database mysql

aq akan menjelaskan bagaimana cara connect ke database mysql yg di phpmyadmin. pertama-tama kita harus buat dulu databasenya di mysql.
1. nama database yg aq gunakan adalah jack
2. nama tabel yg aq pake adalah mahasiswa
3. dalam tabel mahasiswa ada 3 atribut. NIM -> varchar, NAMA -> varchar, Jurusan -> varchar

setelah dimasukkan semua value ke dalam atribut tersebut maka akan bisa menampilkan seperti ini

nah tugas kita skrg adalah menampilkan ketiga value tersebut dalam file php.
1. kita harus membuat file php yg akan melakukan koneksi database. nama file koneksi ini adalah connection.php yg isi-nya sebagai berikut

<?php
    function Connect($db)
    {
        $username = “root”;
        $pswd = “”;
        $con = mysql_connect(“localhost”, $username, $pswd);
        if ($con)
        {
            $conDB = mysql_select_db($db, $con);
        }
    }
?>

setelah itu buat file db.php yang akan melakukan display database mysql seperti ini

<?php
    function Display()
    {
        $query = “SELECT * FROM Mahasiswa”;
        $execute = mysql_query($query) or die(“Can not execute query : “.mysql_error());
       
        while ($result = mysql_fetch_assoc($execute))
        {
            echo “<br><br>NIM     : “.$result["NIM"];
            echo “<br>Nama    : “.$result["NAMA"];
            echo “<br>Jurusan : “.$result["Jurusan"];
        }
    }
?>

nah lalu buat file index.php yang akan menampilkan database mysql di browser

<!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.0 Transitional//EN” “http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”>
<html xmlns=”http://www.w3.org/1999/xhtml”>
<head>
<meta http-equiv=”Content-Type” content=”text/html; charset=utf-8″ />
<title>Skripsi</title>
</head>
<?php
    include “connection.php”;
    include “db.php”;
?>
<body>
<?php
    Connect(“jack”);
    Display();
?>
</body>
</html>

harus di ingat kalau ketiga file ini harus berada di dalam direktori yg sama,direktori yg aq pakai adalah skripsi. nah setelah itu coba jalankan di browser.

http://localhost/skripsi/

maka ntar akan keluar hasil seperti ini di browser.

opera 10.10 final version

I just downloaded opera 10.10 final version and it’s a good browser. there are some feature that I like but first please download the browser here

1. opera turbo
I am loving this feature, I always use it. there are reason why I use this feature very often, it’s just that I use indosatM2 internet connection so sometime the bandwitdh is really slow so I’d have to compress the web pages to make it load faster and opera turbo do just that with an effective way. thanks god opera has this feature.

2. opera link
this is also the other reason why I like to use opera, it’s can synchronize my bookmarks accross entire computer. although firefox can also do this but with the help of an addon so if I go to an internet cafe and I use firefox there I ‘d have to open google bookmarks page first then I can access my bookmarks but with opera all my bookmarks already synced in the browser right from the moment I am signing in.

3. opera unite
this feature make your browser acting kind of like server, I haven’t tried this feature yet because I don’t have sufficient bandwidth so it’s acting a bit slow. maybe later when I’ve got more faster bandwidth I will post my impression here.

4. opera mini
opera mini is the browser I always use in my nokia phone, it also synchronize my bookmarks in opera browser so it really simplified my life.

although maybe you can’t find many addon in opera as you do in firefox because it’s a closed system but nevertheless opera really has made it easy for me to browse the web anywhere and anytime.

GSM Full Rate

Full Rate atau FR atau GSM-FR atau GSM 06.10 adalah standar speech coding digital pertama yang digunakan di GSM digital mobile phone system. Rata-rata bit rate dari codec ini adalah 13 kbit/s. Kualitas dari peng-kodean speech ini termasuk buruk jika di bandingkan dengan standar modern, tapi pada saat pengembangannya (awal 1990-an), GSM Full Rate adalah suatu hal yang bagus dalam hal kompleksitas komputasi dan kualitas. Codec ini masih digunakan dalam jaringan di seluruh dunia. Tapi secara perlahan-lahan GSM Full Rate akan di gantikan oleh standar Enhanced Full Rate dan Adaptive Multi Rate (AMR) yang menyediakan kualitas bicara yang lebih tinggi dengan bit rate yang rendah.

the sampling rate is 8000 sample/s

The average bandwidth of the codec is 13 kbit/s.

Speech encoder mengambil input sebagai 13 bit uniform PCM signal dari sisi audio pada mobile station atau sisi jaringan, dari PTSN via 8 bit A-law or μ-law (PCS 1900) ke 13 bit uniform PCM conversion. Pembicaraan yang telah di encode-kan pada output di speech encoder di kirimkan ke unit channel encoder yang di spesifikasikan di GSM 05.03. Di sisi penerima, operasi yang terjadi kebalikannya.

sampling rate adalah 8000 sample/s, delay transcoder minimum secara teori adalah 20 ms. Requirementnya adalah transcoder delay harus kurang dari 30 ms. Transcoder delay di definisikan sebagai waktu interval antara sebuah speech frame dari 160 sample yang telah diterima pada encoder input dan 160 rekonstruksi speech sample yang telah di out-put oleh speech decoder pada 8 kHz sampel rate.

relevance feedback

relevance feedback adalah mengambil hasil dari pencarian yang dilakukan dengan menggunakan suatu query dan menggunakan informasi tersebut untuk menentukan apakah hasil pencarian tersebut relevan untuk melakukan pencarian dengan query yang baru.

Ada 3 macam jenis relevance feedback

1. explicit feedback : explicit feedback didapatkan dari user yang menentukan relevansi dokumen yang di ambil oleh query. Tipe feedback jenis ini di defenisikan eksplisit karena hanya user yang menentukan feedback yang disediakan itu sebagai dokumen yang relevan. User bisa mengindikasikan relevansi secara eksplisit menggunakan binary atau graded relevance system. Binary relevance feedback menentukan suatu dokumen relevan atau tidak relevan untuk suatu query. Graded relevance feedback mengindikasikan relevansi sebuah dokumen terhadap query menggunakan skala penomoran, huruf atau deskripsi. (seperti “not relevan”.”somewhat relevan”,”relevan”,atau ”very relevant”)

2. Implicit feedback disimpulkan dari sifat user, seperti menentukan dokumen mana yang mereka pilih dan tidak pilih untuk browsing dan durasi lamanya mereka membaca dokumen tersebut. Hal yang membedakan implicit feedback dari eksplisit feedback adalah user tidak menentukan relevansi dokumen untuk keuntungan sistem IR melainkan hanya ingin melakukan untuk kebutuhan mereka dan user tidak diberitahu kalau dokumen yang mereka pilih akan digunakan sebagai relevan feedback

3. Blind or “pseudo” relevance feedback didapatkan dari meng-asumsikan bahwa jumlah k dokumen teratas yang berisi n hasil (yang biasanya k << n) adalah relevant. Blind feedback melakukan automasi dari relevance feedback dan mempunyai keuntungan untuk tidak membutuhkan user yang harus menentukan dokumennya relevan atau tidak karena sudah di automasi.

netsend in vista

I just realize that there are no netsend in windows vista, it’s only available in windows XP. I had to use third party tools of netsend to be able to use it. actually there are others tool similar to netsend namely MSG.EXE but it only available in vista business and ultimate and doesn’t exist in vista home edition in which I am currently using. you can download the third party tools here.

classic game

while I was browsing I found this classic game, the game names is Cadillac and Dinosaurus. I remember playing this game back when I was in elementary school. It really bring back my memory of all the thing that I did during my childhood.

if I am not mistaken I played this game back in 1998 when I was still too young to understand anything about sex. hehe…

but anyway if you want to download this game then you have to download it here
and also you’d need an emulator to play this DOS game. you have to download this tools here

you first have to load the game using an emulator, and click on all the visible game so it will list all the visible game that exist in the directory and then click the cadillac and dinosaurus. don’t forget to set the key so it would be easier for you to play the game using your keyboard.  I heard someone say that music brings your old memory back, but for me when playing this game then it did brings all my memory of my childhood.

BSOD (blue screen of death)

I use vista now, and I sometime got this blue screen things everytime I use vista. And god knows why did it happen. I haven’t found any single clue why BSOD always happen and what preventive measure that can be done to address it.

The “Blue Screen of Death” is an ominously nondescript blue screen alerting the user that, for any number of reasons, the computer must shut down to prevent further damage. This screen is accompanied by text, of which much is unintelligible to all but the most tech savvy.

this is an example of blue screen.

to know what happen with your computer and the reason why is has a blue screen then you can try this small utility called BlueScreenView

BlueScreenView is an informative utility that operates as a interpreter of sorts, taking what many find to be incomprehensible and processing  that information in a manner that makes it a bit easier to digest. The necessity of a utility like BlueScreenView becomes obvious when observing how little time you have before the “Blue Screen of Death” proceeds with a system reboot.

With BlueScreenView, the user can access BSOD dump file, filtering that information through a report that’s just a bit easier to understand. When launching the application, it will scan for the minidump files generated by the system crash, which are usually located in C:\windows\minidump. Taking that data, it displays it in a window, with the dump file listed above and those drivers associated with the crash sorted below.

so you need to use bluescreen if you use windows and trust me you gonna need it. to download bluescreenview you can try it here

all the novel that I have read

I always like to read book, especially a novel. here I will list some of the novel that I have read.

1. Sidney Sheldon – The Best Laid Plans

2. Sidney Sheldon – Windmills of the Gods

3. Sidney Sheldon – Doomsday Conspiracy

4. Sidney Sheldon – Tell me Your Secret

5. Sidney Sheldon – Bloodline

6. Sidney Sheldon – The Stars Shine Down

7. Sidney Sheldon – Nothing Lasts Forever

8. Sandra Brown – Chill Factor

9. Sandra Brown – The Switch

10. Stephen King – Rose Madder

11. Stephen King – Cell

of all the author of these novel, my favourite author is Stephen King and Sandra Brown, where as Sidney Sheldon is a bit boring in terms of it story. Although I read a lot of his novel. For me Stephen King is the best, the story line is genious and he can describe the situation in the story really well and I kinda like it. Also Sandra Brown really great at narrating the story. But my best author is Stephen King, he is also a film director and to be honest watching his film really is creepy sometime and intense. Well, if there are any good novel out there that I haven’t read, just let me know then.
