Vista Gadget : Template, Intellisense & RunVistaGadget Add-In

reyza — Sun, 20 Jul 2008 15:59:24 GMT

Terlebih dahulu bisa kunjungi ini, ini dan ini.

Apa yang dibutuhkan seorang programmer saat membuat aplikasi?

Jawabannya :

Ketersediaan template aplikasi sehingga tidak perlu pusing membuat satu-satu file yang dibutuhkan.
Kemudahan menulis kode program dengan bantuan intellisense.
Kemudahan untuk test/run aplikasi yang telah dibuat.

{Template Vista Gadget Project}

Cukup berkunjung ke posting Create a Vista Gadget Using Visual Studio IDE maka anda akan mendapatkan template Vista Gadget Project. Template ini akan dapat anda lihat pada kelompok Web Site.

Hasil dari tempat ini dapat dilihat pada gambar berikut :

{Intellisense}

Menulis program tanpa Intellisense sungguh menyusahkan, apalagi Vista Sidebar Object Model adalah barang baru jadi kode-kodenya semua berada di luar kepala (alias : tidak ada satupun yang melekat di kepala ).

Tetapi bila berkunjung ke posting JavaScript IntelliSense for the Vista Sidebar Object Model maka Visual Studio 2008 (karena hanya versi ini yang support Javascript Intellisense) dapat disulap untuk memberikan kemudahaan dalam menulis kode-kode saat bersuka-ria dengan Vista Gadget.

Ada dua file yang dibutuhkan untuk menikmati kemudahan ini, yaitu :

MicrosoftAjax.debug.js, file ini dapat ditemui pada MicrosoftAjaxLibrary. Untuk mendapatkan file ini dapat berkunjung ke http://www.asp.net/ajax/. Ambil yang versi 1.0 saja, untuk sekarang lupakan yang versi 3.5. Kenapa? Bisa dicoba sendiri untuk mendapatkan jawabnya :)
Sidebar.IntelliSense.js, file ini dapat didownload pada link berikut ini.

Setelah itu, kedua file ini dapat dimasukkan ke dalam folder scripts (untuk sementara).

Bila anda bekerja pada halaman HTML, maka perlu ditambahkan baris seperti berikut :

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title>Untitled Page</title>
    <link href="css/gadget.css"  type="text/css" rel="Stylesheet"/>
    <script src="scripts/gadget.js" type="text/javascript"></script>
    <script src="scripts/MicrosoftAjax.debug.js" type="text/javascript">

    </script>
    <script src="scripts/Sidebar.IntelliSense.js" type="text/javascript">

    </script>
</head>

Bila bekerja pada file JS, maka cukup baris berikut yang ditambahkan.

/// <reference path="MicrosoftAjax.debug.js" />
/// <reference path="Sidebar.IntelliSense.js" />

Setelah itu, maka kemudahan seperti di bawah ini dapat anda nikmati.

{Testing Vista Gadget}

Dengan menggunakan Run Vista Gadget Add-In yang dapat di-unduh di sini. Maka anda dapat melihat tambahan menu RunVistaGadget seperti pada gambar berikut.

I love google, I love internet, semuanya sudah tersedia diluar sana, tinggal bersenang-senang mengerjakan PR (pekerjaan rumah) dengan Vista Gadget.

Merging, Non-Merging Parallelism

Merging, Non-Merging Parallelism

By : Kasim Wirama, MCDBA

This posting, I delve deeper into parallelism operator in execution plan. Parallelism is knows as exchange operator. It is named as exchange operator because producer threads distribute rows into consumer threads. If you are interested to know more, let’s look into further explanation about internals of parallelism operator.

In case of one producer, rows will be sent to consumer threads and this type of parallelism is called distribute stream parallelism. In case of multiple producers, there might be single consumer thread or multi consumer threads. For single consumer thread, it is called gather stream parallelism, and for multi consumer threads, it is called repartition stream parallelism.

How rows are distributed in terms of repartition and distribute stream parallelism? There are 5 algorithms that might be applied into them. They are broadcast, round robin, hash, demand, and range algorithm. For broadcast and round robin algorithm implementation, let’s browse my previous posting (http://geeks.netindonesia.net/blogs/kasim.wirama/archive/2008/07/20/round-robin-algorithm-in-distribute-stream-parallelism-of-sql-server-execution-plan.aspx and http://geeks.netindonesia.net/blogs/kasim.wirama/archive/2008/07/20/broadcast-algorithm-in-distribute-stream-parallelism-of-sql-server-execution-plan.aspx). Hash algorithm works by getting hash value of one or more columns in each row that would be matched into build tables. To get sense of hash algorithm, let browse to my historical posting in http://geeks.netindonesia.net/blogs/kasim.wirama/archive/2008/05/18/nested-loop-merge-join-and-hash-join-algorithm.aspx. Feel free to visit my SQL Server Knowledge Center. J Next algorithm is Demand partitioning. It works on parallel scan on partitioned table. Internally, producer threads will ask consumer threads for rows. Other algorithm is Range algorithm. It works by examining a column for each input rows to list of range of values.

In multiple consumer threads like repartition and gather streams parallelism, there will be merging exchange and distribute streams parallelism is categorized into non-merging exchange. What do merging and non-merging exchange means? Merging exchange is type of parallelism which each consumer threads will receive rows from producer threads in sorted order. Rows in sorted order will be implemented either by explicitly by SORT operator or implicitly by utilizing applicable index. Merging exchange has blocking nature and it is less optimized in performance aspect. In some cases, it will cause degrade performance. And sometimes, you will find out that a query will be deadlocked by itself. Such a deadlock is called parallel deadlock. The probability of parallel deadlock will increase when degree of parallelism is high. To detect this parallel deadlock, you query DMV sys.dm_os_waiting_task, and look at wait_type column. If wait_type contains CXPACKET in same session with different threads, it shows parallel deadlock. Solution for this issue is to lower down degree of parallelism or force to a serial plan or rewrite problematic query.

Not all parallelism is considered sub optimal, distribute streams with broadcast and parallel scan without round robin implementation are examples of good type of parallelism. With the knowledge in your hands, you could identify the suboptimal operator in parallelism and devise a better execution plan for database performance.

Broadcast Algorithm in Distribute Stream Parallelism of SQL Server Execution Plan

Broadcast Algorithm in Distribute Stream Parallelism of SQL Server Execution Plan

By : Kasim Wirama, MCDBA

I have shown you round robin implementation in distribute stream. From performance perspective, round robin is less desirable type of parallelism because it implements no load balancing. But there is good type of parallelism, which is broadcast parallelism which I would explain further on this posting.

Basic knowledge of parallelism is that you need to know parallelism operator contains 2/more threads, which is internally contains 2 groups of operator composition, i.e., producer and consumer. For broadcasting in distribute stream parallelism, all rows will be sent from each of producer to all consumers. Parallelism on consumers side will impact on parallel scan on the underlying tables.

I take script example from “Parallelism in Nested Loop” posting (http://geeks.netindonesia.net/blogs/kasim.wirama/archive/2008/07/12/parallelism-in-nested-loop.aspx). After that, turn on graphical execution plan toolbar, and execute the following query here :

select a.col1, a.col2, a.col3, b.col2, b.col3

from bigtable a

join anotherbigtable b

on a.col2 = b.col2

where a.col1 = 0

Execution plan for the query is :

|--Parallelism(Gather Streams)

|--Nested Loops(Inner Join, WHERE:([tempdb].[dbo].[anotherbigtable].[col2] AS [ b ].[col2]=[tempdb].[dbo].[bigtable].[col2] AS [ a ].[col2]))

|--Parallelism(Distribute Streams, Broadcast Partitioning)

| |--Clustered Index Seek(OBJECT:([tempdb].[dbo].[bigtable].[PK__bigtable__182C9B23] AS [ a ]), SEEK:([ a ].[col1]=(0)) ORDERED FORWAR(D)

|--Clustered Index Scan(OBJECT:([tempdb].[dbo].[anotherbigtable].[PK__anotherbigtable__5EBF139D] AS [ b ]))

See the execution plan above, all rows from outer query (bigtable) will be sent under broadcast partitioning parallelism context to inner query (anotherbigtable) and there is no OUTER REFERENCE in Nested Loops operator. So threads in inner query will cooperate among another to scan underlying table which is anotherbigtable object. As I mentioned that parallelism in nested loop operator will be parallel only in outer query, serial plan is still applied on inner query. But it has exception when there is broadcast partitioning on distribute stream, so both outer and inner query are under parallelism operation, which is good for performance perspective.

Round Robin Algorithm in Distribute Stream Parallelism of SQL Server Execution Plan

Round Robin Algorithm in Distribute Stream Parallelism of SQL Server Execution Plan

By : Kasim Wirama, MCDBA

I would like to show round robin implementation in distribute stream parallelism. Before I talk about round robin specific in distribute stream parallelism, let revisit about distribute stream parallelism.

In internal execution plan generated by optimizer, parallelism contains two or more threads, and each threads could have one/more producers and one/more subscribers. In case of distribute stream parallelism, there is one producer thread and two or more consumer threads. So we move further to round robin discussion specific to distribute stream in parallelism.

select

t1.col1, t1.col2, t1.col3

from

(

select top 100

col1, col2, col3

from bigtable

order by col2

) as t1

join anotherbigtable as t2

on t1.col1 = t2.col1

Execution plan for the query is :

|--Parallelism(Gather Streams)

|--Nested Loops(Inner Join, OUTER REFERENCES:([tempdb].[dbo].[bigtable].[col1], [Expr1005]) WITH

|--Parallelism(Distribute Streams, RoundRobin Partitioning)

| |--Top(TOP EXPRESSION:((100)))

| |--Parallelism(Gather Streams, ORDER BY:([tempdb].[dbo].[bigtable].[col2] ASC))

| |--Sort(TOP 100, ORDER BY:([tempdb].[dbo].[bigtable].[col2] ASC))

| |--Clustered Index Scan(OBJECT:([tempdb].[dbo].[bigtable].[PK__bigtable__182C9B23]))

|--Clustered Index Seek(OBJECT:([tempdb].[dbo].[anotherbigtable].[PK__anotherbigtable__5EBF139D] AS [t2]), SEEK:([t2].[col1]=[tempdb].[dbo].[bigtable].[col1]) ORDERED FORWARD)

I find out there 3 parallelisms, the first parallelism comes immediately after SORT operator, this is parallel scan, and just because TOP (n) requires single thread execution, so first parallelism is gather stream parallelism. The second parallelism is round robin partitioning, it means that it distribute sets of rows for multi threads in Nested Loops operator. And the topmost is gather stream parallelism.

In performance perspective, round robin partitioning is less desired operator because it handles no load balancing, and it is execution will stop here to gather complete TOP (n) records.

Parallelism is not bad at all, but there is some kinds of parallelism you need to be aware about and take appropriate action to correct the execution plan either by indexing or rewriting a problematic query.

5 Big Security Threats

meidianto — Sun, 20 Jul 2008 10:08:00 GMT

Traditional anti-virus software and firewalls miss these five current threats.

1 Trusted Users and Partners
These individuals have access to your most sensitive data. Without additional monitoring and policy enforcement technology in place, organizations are left flapping in the wind.

2 Web Application Vulnerabilities
Gartner estimates that 75 percent of today’s attacks are carried out through the application layer. Many of these application attacks are conducted through quickly coded Web applications, with little or no security baked in. Yet these Web apps are often connected to some of the most sensitive databases businesses own.

3 Missing Devices
Whether lost or stolen, unencrypted laptops and other mobile devices have the potential to expose your organization to high-profile data breaches if they contain sensitive information.

4 Custom Malware
Most security experts agree that signature-based anti-virus systems are overwhelmed by the proliferation of malware designed to fly under the radar of established signatures to attack systems and steal data. Signature-based protection cannot protect against custom malware that has never been detected before.

5 Social Engineering
When users provide log-in information to a “tech support” guy who doesn’t exist, or they unknowingly respond to spear-phishing attempts to steal their credentials, the bad guys gain unfettered access to your systems. These tricky attacks that prey on user ignorance must be headed off through education, policy creation and enforcement measures.

Hand on Lab : ASP.NET 3.5

reyza — Sun, 20 Jul 2008 09:58:15 GMT

Kesulitan belajar Visual Studio 2008 karena belum banyak yang berbahasa Indonesia ?

Kesulitan belajar C# 3.0 karena belum banyak yang berbahasa Indonesia ?

Kesulitan belajar ASP.NET 3.5 karena belum banyak yang berbahasa Indonesia ?

Kesulitan belajar ASP.NET Ajax dan Ajax Control Toolkit karena belum banyak yang berbahasa Indonesia ?

Ini ada sedikit oleh-oleh karena habis mengadakan In House Training di PT MSP salah satu ISV di Bandung yang sudah dikenal dengan basis teknologi PHP dan Delphi. Oleh-oleh berupa modul training. Isinya masih jauh dari bagus, saya juga yakin banyak istilah yang salah atau hal-hal lainnya. Maka oleh dari itu butuh masukan untuk perbaikan bahkan tambahan konsep-konsep pendukung. Apalagi masih ada 1 bab yang belum selesai dibuat, bab yang membahas tentang Report, yang direncanakan menggunakan Report Viewer dan Crystal Report .NET. Tetapi Insyallah bab tersebut akan dibuat (entah kapan).

Walaupun jauh dari garis batas bagus harapannya modul ini masih berfungsi untuk membantu pemula agar mendapatkan bayangan tentang ASP.NET dan fasilitas-fasilitas yang dapat memudahkan dalam membangun aplikasi web dengan ASP.NET.

Berikut ini daftar isi dari modul ini.

Daftar Isi

1 Pendahuluan
2 .NET 3.5 & Visual Studio 2008
3 Pengenalan C#
4 ASP.NET
5 ASP.NET dan Database
6 Design Antarmuka
7 Resource & Globalization
8 Validasi
9 ASP.NET Ajax dan Ajax Control Toolkit
10 Membership, Profile dan Navigasi

Bagi yang ingin membaca daftar isi terlebih dahulu dapat mengunduh ini : HandOnLab_ASP.NET_3.5_DaftarIsi.pdf (format PDF, size :183KB).

Expression Web 2 PHP IntelliSense Support

sagi — Sat, 19 Jul 2008 01:41:41 GMT

"menyikapi" postingan pak Risman tentang php intelisense support pada Expression Web 2, saya tergoda untuk mecobanya sendiri.

memang suatu hal yang menarik pada Expression Web 2 adalaha adanya php intelisense support. bagi saya yang biasa coding php menggunakan Notepad++ saya menemukan fitur yang sama persis dan cukup membantu, yaitu code coloring. Bukan cuma itu, pada Expression Web 2 ini, suatu fitur yang sering saya temui pada Visual Studio juga ada di sini, yaitu Intelisense untuk php.

Namun berbeda dengan Intelisennse nya Visual Studio, dimana C# compile ditanam (diintegrasikan) dalam Visual Studio nya. pada Expression Web 2 ini, php tidak ditanam pada Expression Web 2 ini, nampaknya yang ada adalah intellisense untuk native php function. Hal ini dikarenakan tidak dilakukannya partial ~~compile~~ Interpret dengan php.exe oleh Expression Web 2 seperti hal nya yang dilakukan Visual Studio untuk men-generate Intelisense ada C#

Tampilan dari Expression Web 2 ini mirip dengan Sharepoint Designer yang juga memiliki fungsional yang hampir sama, yaitu HTML Editor, namun Expression Web 2 ini tidak mensupport Sharepoint tentunya :)

Page File dan Indexing di Vista

hafiz_ar99 — Fri, 18 Jul 2008 08:48:00 GMT

Beberapa hari ini sempet bertanya-tanya, perasaan gw nginstall macem2 di laptop gw cuma sekitar 25 Giga an, tapi ko serasa sampe 35 Giga an ya?

Setelah diselidiki dan bertanya2 ama sagi, ternyata ada kemungkinan Indexing di drive vistanya yang makan harddisk lumayan banyak. Biasanya kalo di PC rumah, gw cukup masuk ke Windows XP, dan ga tau (belom tau) mekanismenya gimana drive vista dikomputer rumah gw kembali normal. Tapi kan dilaptop gw kaga ada tuh windows xp nya. Y sudah, dicoba lah cara manual pake clean up disk, trus indexingnya dimatiin trus direstart. Hasilnya lumayan, drive vista di laptop gw nambah 5 Giga.

Penasaran lagi, matiin ah Page File di drive C nya, blom tau nih efeknya apaan, di vista siy warningnya cuma:

"kalo ada error ga dicatet" -- kira2 gitu katanya.

Trus gw restart komputer, lumayan sekarang nambah 3 Giga, jadi total gw mendapatkan kembali 8 Giga yang kemaren hilang.

Deploy ASP.NET 3.5 Application on Windows XP with IIS 5

hafiz_ar99 — Fri, 18 Jul 2008 08:38:00 GMT

Aaaah finally, my first post at geeks.

Kelamaan menggunakan Vista jadi bikin kagok pas mau maen2 sama IIS di Windows XP.
Kalo di vista nginstall IIS tinggal Turn on windows feature klik klik klik, install.
Ga perlu pake CD installer. Nah, yang jadi masalah pas nginstal IIS di XP, jreng, ternyata
minta CD installer Windows XP. Untung ada yang minjemin.

Add or Remove Program -> Add or Remove Windows Component, kemudian check yang Internet
Information Service, klik detialnya, trus di Check deh World Wide Webnya.

Instalasi selese, cek di browser: Http://localhost, boom, berhasil.

Di laptop yang gw install IISnya ini, udah diinstal juga .NET Framework 1.1, 2.0, bahkan 3.0.
Maka gwcobalah, bikin file baru di C:\inetpub\wwwroot\tes\tes.aspx
Ternyata yang terjadi adalah server unavailable..

Kecurigaan pertama, di settingan Default Websitenya, pada propertiesnya ternyata pada
tab ASP.NET belom dipilih .NET 2.0xxxx

setelah di pilih dan diapply. Loh ko, malah ga bisa sama sekali IISnya. Cek sana sini, akhirnya
gwcoba iisreset, ternyata manjur. Tapi masi tetep ga bisa buka tes.aspx dan file2 lain yang berekstensi
*.aspx

Kenapa ini, kenapa??, mana harus di deploy di laptop itu juga lagi. Akhirnya setelah bergoogling ria, gw
menemukan ternyata kita harus melakukan registrasi dulu frameworknya dengan cara

di cmd masuk ke %windir%\Microsoft.NET\Framework\vx.xxxx\aspnet_regiis.exe -i

dan ternyata berhasil. Aaaaah, tenangnya, akhirnya bisa pulang. Tinggal nunggu instalasi .NET Framework 3.5
selese diinstall.

Nah, abis diinstal .net 3.5 nya. Asumsi gw, gw musti ganti lagi settingan di IISnya supaya framework .net yang
dipake yang 3.5. Ternyata ga ada pilihannya. Dan setelah dicari2 emang di IIS, yang dipake tulisannya tetep 2.0
tapi dengan penambahan library yang banyak dari .net 3.5

Akhirnya berhasil di deploy juga tu aplikasi. Tinggal nunggu demo besok. Mudah2an ga ada trouble.

Bisa tidur dengan nyenyak malem ini.

SSCLI 2.0 with VC++ 2008 on Vista

Risman Adnan Mattotorang — Wed, 16 Jul 2008 08:00:51 GMT

I tried to compile SSCLI 2.0 with VC++ 2008 on Vista, and again, too many error messages, due to :

- Change of Windows Vista SDK include path and directory name
- SUBSYSTEM_WINVER = ,4.00 and SUBSYSTEM_CONVER = ,4.00 changed to ,5.00
- Incompatible warning level = -Wp64 (I am using 32 bit)
- Change of compiler (_MSC_VER ==1500) & runtime versions (_MSVCRT MSVCR90)

Basically you can do find and replace through all SSCLI source codes, but I strongly suggest you to follow Jeremy Kuhne manual steps. Once you done, just run env.bat and then buildall again. He also gives useful tips regarding the MSBUILD and VS Template for SSCLI.

Enjoy learning CLR through SSCLI Codes!

SSRS

cipto — Wed, 16 Jul 2008 03:56:00 GMT

whoah it's been 1 days to solve this issue,

everything below is using local report with SSRS not report server.

when using localreport with Microsoft report viewer, been quite a mystery, when somethings got wrong , it just display simple error which also a mystery. i search the net but found not a brief explanation

any way , when you are using sub report, the trouble gots higher.

you've got to manually bind the value for each object data source.

First step is to add event handler

Page load

{

     ReportViewer1.LocalReport.SubreportProcessing += new Microsoft.Reporting.WebForms.SubreportProcessingEventHandler(LocalReport_SubreportProcessing);
        ReportViewer1.ReportRefresh += new System.ComponentModel.CancelEventHandler(ReportViewer1_ReportRefresh);
    }

    void ReportViewer1_ReportRefresh(object sender, System.ComponentModel.CancelEventArgs e)
    {
        ObjectDataSource1.DataBind();
        ObjectDataSource2.DataBind();
        ObjectDataSource3.DataBind();
    }
////this is processed row by row

//you've got to attach the report parameter to object datasource

//on local mode you need to do this

   void LocalReport_SubreportProcessing(object sender, Microsoft.Reporting.WebForms.SubreportProcessingEventArgs e)
    {
        e.DataSources.Add(new ReportDataSource("SubWipproposal_WipProposal", "ObjectDataSource2"));
        ObjectDataSource2.SelectParameters[0].DefaultValue = e.Parameters[0].Values[0];
        e.DataSources.Add(new ReportDataSource("PipeLineDataset_GetProducttype", "ObjectDataSource3"));
        ObjectDataSource3.SelectParameters[0].DefaultValue = e.Parameters[1].Values[0];
        ObjectDataSource3.SelectParameters[1].DefaultValue = e.Parameters[0].Values[0];

    }

Error: SubReport could not be shown

Solution:

1.Check every data source: the main report and the sub report , by clicking vside menu , report ->Datasource , already included the source of your report, add as necessary

2.Check the naming of the dataset,report ->Datasource,must match from the add report datasourcename (case sensitive) on subreportprocessing event

3.CHeck that your sub report parameters already define the same as the parameters being pass from main report

Error: "Text box.A Scope..."

Solution: for multiple dataset in one report you need to define the scope of each textbox. for ex:(=First(Fields!producttype.Value, "PipeLineDataset_GetProducttype") the bold one is the scope

when using multiple datasource, it's better to use .List and then in that list there's a sub report

Hope this help

Mark as answer :) :)

Password User BlogEngine.NET 1.4 telah Terenkripsi

cahnom — Wed, 16 Jul 2008 01:50:51 GMT

Akhirnya password user BlogEngine.NET dienkripsi juga. Hampir dua tahun pake BlogEngine.NET sejak versi 0.8, password dalam file XML disimpan dalam plain text. Setelah versi terbaru (1.4) akhirnya password dienkrip dengan algoritma SHA256. Kita bisa intip kode enkripsi password yang digunakan BlogEngine.NET sebagai berikut.

/// <summary>
/// Encrypts a string using the SHA256 algorithm.
/// </summary>
public static string HashPassword(string plainMessage)
{
    byte[] data = Encoding.UTF8.GetBytes(plainMessage);
    using (HashAlgorithm sha = new SHA256Managed())
    {
        byte[] encryptedBytes = sha.TransformFinalBlock(data, 0, data.Length);
        return Convert.ToBase64String(sha.Hash);
    }
}

Pada file User.xml yang sebelumnya tidak dienkripsi sekarang sudah terenkripsi seperti terlihat pada kode berikut.

<Users>
  <User>
    <UserName>Admin</UserName>
    <Password>jGl25bVBBBW96Qi9Te4V37Fnqchz/Eu4qB9vKrRIqRg=</Password>
    <Email>post@example.com</Email>
    <LastLoginTime>2007-12-05 20:46:40</LastLoginTime>
  </User>
  <User>
    <UserName>mads</UserName>
    <Password>JXMu9HdxF4mOBSAx4DrWOPAzJt58v+/sHfrxoko0m0M=</Password>
    <Email>mads@zyb.dk</Email>
    <LastLoginTime>2008-07-07 19:11:41</LastLoginTime>
  </User>
</Users>

Seperti terlihat pada kode di atas bahwa password telah terenkripsi. Teks password sebenarnya tidak dapat terbaca. Password standar BlogEngine.NET untuk user Admin adalah "admin" tanpa tanda kutip.
Akhirnya bisa lebih tenang karena password saya tidak bisa diintip lagi oleh admin hosting. Sorry ya mas Rudy... Hehehe...

Hidden Markov Model

norman — Wed, 16 Jul 2008 01:36:00 GMT

Last semester I found Hidden Markov Model in "Mathematics & Statistics for Computing" class, this semester I found it in "Computational Intelligence" class, next semester I'll find it in "Pattern Recognition" class. Even in a song, I find Hidden Markov Model.

Look at the lyrics I put on may last post...

Like the flower and the scent of summer,
Like the sun and the shine,
Well the truth may come in strange disguises,
Send the message to your mind

I think it's the most poetic and beautiful expression of Hidden Markov Model!

PayPal Verification: Akhirnya Verified Juga

cahnom — Wed, 16 Jul 2008 01:20:04 GMT

Alhamdulillah, setelah beberapa bulan semenjak account bank Indonesia dapat menerima pembayaran dari PayPal, saya coba untuk verify beberapa debit card yang saya miliki. Satupun tidak ada yang dapat di-verify baik BCA, BNI dan terakhir Bank Niaga.

Karena semua debit card yang saya miliki tidak dapat digunakan akhirnya saya coba untuk apply kartu kredit Citibank. Setelah melalui proses verifikasi kartu kredit hampir satu bulan, akhirnya minggu kemaren kartu kredit diantar oleh kurir ke kantor. Dengan kartu kredit yang baru ini saya coba verify ke paypal. Setelah menunggu selama dua hari untuk mendapatkan empat digit PayPal code, akhirnya datang juga PayPal code di account detail citibank online saya.

Sekarang saatnya untuk berburu dollar di dunia maya. Merdeka!!!
