Hari ini Microsoft Indonesia resmi merilis Windows 7 di JCC (Jacarta Convention Center) 24 November 2009. Dengan mengusung tema “New Efficiency” nampaknya terlihat jelas bahwa Microsoft telah belajar dari kegagalan sebelumnya saat penjualan sistem operasi Windows Vista yang kurang baik.

Seperti kita ketahui — para pengguna setia Microsoft sebisa mungkin tidak akan menggunakan Windows Vista yang “rakus” spesifikasi hardware. Para pengguna yang berasal dari berbagai kalangan mulai dari pengguna rumahan bahkan pengguna dari korporasi pun harus berpikir matang untuk mengupgrade Windows XP ke Windows Vista. Alasan mendasar dari membuat pengguna XP enggan beralih ke Vista adalah Windows Vista tidak dapat berjalan dengan spesifikasi hardware yang digunakan Windows XP.

Salah seorang teman saya yang bekerja sebagai staff IT di sebuah perusahaan finance terkenal di Jakarta mengutarakan bahwa dia di kantornya harus “downgrade” ke “Windows XP Mode” agar PC yang ada di kantornya tetap dapat digunakan tanpa harus membeli PC yang baru.

Berkaca dari pengalaman kegagalan pada penjualan Windows Vista secara global yang menunjukkan tren yang kurang baik dibandingkan dengan hasil keuntungan yang diraih Microsoft saat memasarkan Windows XP.  Pada gelaran Launching Windows 7 kali ini dijelaskan bahwa Windows 7 dapat berjalan di PC lama tanpa ada masalah, bahkan dalam salah satu forum teknlogi informasi membuat ulasan mengenai pengalaman instalasi Windows 7 pada Komputer Pentium 4 Dengan Memori 256MB.

Kesimpulan penulis mengenai dengan rilis terbaru dari sistem operasi desktop terbaru dari Microsoft Windows, terlihat jelas bahwa pengalaman adalah ilmu yang paling berharga, lihat saja perusahaan sebesar dan sekaliber Microsoft milik Bill Gates harus meredefinisi ulang Windows Vista dengan nama baru yaitu Windows 7 yang dapat berjalan pada komputer dibawah spesifikasi Hardware yang dibutuhkan oleh Windows Vista. Gambar disamping kanan menunjukkan Windows Experience Index Score, semakin besar score yang diberikan, semakin besar performance yang diberikan dalam bekerja dengan Windows Vista.

Just like most people, i downloaded and installed SharePoint 2010 last week. Unlike mentioned, I had no issues while installing on Windows 2008 R2 environment. It’s been a week and still no issues.

Looks like it’s going to take a while for me to get used to new ribbon interface. Definitely you get to see and do more with ribbon, but will take a some time to remember what is where.

Actually, main focus of this post is a lot mentioned new feature of SharePoint 2010. ”Limitation on number of items stored in a list”  problem seems to be solved – Now, SharePoint lists can handle millions of items.

In order to see this, I decided to do a little experiment. My aim is firstly to insert one million items in a list successfully. As I write this post items are still being inserted, 731371 and still counting… So far it’s been 6 hours and still inserting.

I have to also mention that my experiment environment is done on a  Win 2008 R2 with 2 GB Ram and using an external usb hdd. So this waiting time can be way less if you try with a powerful workstation. Anyhow, how do I insert 1 million items to a list? Of course using PowerShell script..

Here is a very simple PowerShell script which inserts items to a list. This script is just assigning ‘Title’ column values: Item – ItemNo

========================================================================================

// Set site url
$siteurl = “http://yourservername”

// get site obj
$mysite=new-object Microsoft.SharePoint.SPSite($siteurl)

// open root web
$spWeb = $mysite.OpenWeb()
 
// get test list obj
$spList = $spWeb.Lists["TestList"]

// Insert 1 million items
$i = 1001

do { Write-Host “Item – “$i
         $spitem = $spList.Items.Add() 
         $spitem["Title"] = $i.tostring()
         $spitem.Update()
         $i++
}
while ($i -le 1000000)

========================================================================================

Will update this post once insert operation is completed…

(next morning)

Ok, now i see insert operation is completed. As you can see below, one million list items are inserted into a list using PowerShell.

At this point I’d like to do some test re item select/update/delete operations. Also wondering how filtering is going to work in such a large list. If you have suggestions for other tests or things to check, please let me know, i’ll try to apply them as well. At the end, I’d like to have a some sort of comfort level while suggesting a client ‘one million item is ok in a SharePoint 2010 list’.

Pass ! : First Experience with Ruby on Rails 

This follows installation of Ruby on Rails (RoR) in the Windows (XP/Vista) environment. Products that I have chosen for this application development environment are as follows.

• MySQL Community Server 5.1 which can be downloaded from http://dev.mysql.com/downloads/mysql/5.1.html
• Ruby 1.8.6-27 RC2 which can be downloaded from site http://rubyforge.org/frs/?group_id=167 [use the one click installer ruby186-27_rc2.exe ]

First part of the installation was to set up the MySQL Server. [Installation of the server is quite easy with recommended setting ]. The username and password for this set up will be U:ror and P:ruby.After configuring the database server, its time to set up environment for the Ruby programming language. For this, the package that has been downloaded from the RubyForge website will be used. This one click installer package will set up the environment for Ruby [be sure to select the SciTE option in the installation wizard. The SciTE application makes it easy to edit Ruby scripts]. The installation directory will be C:\ruby>. Now, its time to install the rails. For this, proceed as follows

• Open command prompt, and hit the command "gem install rails –include-dependencies"
  >gem install rails –include-dependencies {look at the fig below}. To perform this action, internet connection should be available all the time.
  

Fig 1 Installing Rails

• Now lets install the gem for mysql with the command "gem install mysql" {see the fig below}
  >gem install mysql

Fig 2 Installing MySQL Gem 

• It is always better to update the gems. So for updating the installed gems to a newer version run the following command [internet connection should be available].
  >gem update –system  {or simply >gem update}

  

     Fig 3 Updating Gem

After this your workstation is ready for RoR web application development. Wait, actually we are not finished here. [I don’t know if it is the problem faced alone by me or somebody else also, I got a lot of problems after this process. This process is defined in most of the books but what they lack is perspective from user side. They left the problems for us to solve. I’ll try to explain some of them here.].

This is the time to make first application on RoR {you know how to this, isn’t it? Just the command “>rails your_application_name”; “your_application_name>ruby scripts/generate controller App” and then some configuration on application controller file, and a template for viewing. After that we are ready to go}. This application generation will also generate a “database.yml” file in application folder. By default Ruby on Rails uses SQLLite database and here we are using mysql. So, edit the “database.yml” file file as follows

development:
     adapter : mysql
     database : my_database_name
     username : my_username
     password : my_password

Now, its time to run the web server [RoR uses WEBrick web server and by default uses port 3000]. hit the command
               >ruby script/server  {it will look like the following fig.}

Fig 4 Running web server

Everything should be running this time {cross your fingers}. There is one bug in MySQL Server. After a fresh install, mysql doesn’t copy the libmysql.dll in the system32 folder. The file can be found in the installation directory of mysql server. We just have to copy and paste the file.

Enjoy riding Ruby on Rails.

Here is a nice javascript snippet which allows you to read querystring parameter values. Actually i used this code in a SharePoint application page to read ListId and ItemId values that i was passing from previous page.

// ************************************************************
// Create an array to keep query string variables
var qsParm = new Array();
// This function gets query string values from current page
// and stores them in above defined array
function qs()
    {
            var query = window.location.search.substring(1);
            var parms = query.split(‘&’);
           
            for (var i=0; i<parms.length; i++) {
                var pos = parms[i].indexOf(‘=’);
                if (pos > 0)
                {
                    var key = parms[i].substring(0,pos);
                    var val = parms[i].substring(pos+1);
                    qsParm[key] = val;
                }
            }
    }

qsParm['ListId'] = null;
qsParm['ItemId'] = null;
// Call function – get query strings
qs();
// For example show ListId
alert(qsParm['ListId'])
// ************************************************************

dari dulu pengen beli HD external buat back up data ma biar bisa dibawa kemana-mana. dan akhirnya siang ini tadi beli HD external juga. sebelum ke toko komputer buat beli masih bingung karena banyak kandidat merk HD external yang lagi ready stock. kandidat ada WD my passport, Seagate Free Agent, Buffalo MiniStationLite. cari yang cepet transfer plus baca data. Akhirnya beli yang Buffal MiniStationState 320GB warna ruby red harganya 600 ribuan (sensored) ^^.

buffalo bukan cuma brand HD external tapi juga memproduksi blu ray writer, card reader, LCD, USB, SYstem Unit, dan masih banyak lagi. keunggulan dari produk HD external merk Buffalo ini adalah kecepatannya. include turbo USB yang bikin cepet read or write data. untuk masalah pilihan warna ada ruby red, crystal black dan pearl white. ukurannya 2.5 inch dijual mulai kapasitas 250 GB – 500 GB. tadi pas baru plug HD ini ke laptop udah tidak usah format lagi malah udah ada aplikasi-aplikasi bawaannya. compatible buat PC, laptop, mac and all OS. ultra slim, tipis ma enteng juga ini HD external. terus juga ada fitur Encryption Software Included.

In this 2nd part of the article, I’ll mention installation environment details. Although SAP doesn’t recommend installation on laptops, I did my test installation on a virtual machine. As host machine I used Windows 7 Ultimate 64bit and VMware Workstation. Here are guest 64bit operation system details:

=========================================================================================

Installation Guest Machine details

* Windows Server 2003 R2 – Standard x64 Edition

* MS SQL Server 2008 x64 with collation CP850_BIN2 (this is very important. you can only install SAP with this collation)

* Java JDK 1.4.2_17 windows-amd 64bit. If you have problems finding a 64bit version for Java 1.4.2_? SDK, here is the link: http://java.sun.com/j2se/1.4.2/SAPsite/download.html

Java SDK versions provided in above link are specific builds for SAP customers. For my installation, I used following version.

Also, you should download Java Cryptography Extension 1.4.2 since SAP Installer will ask for it during installation.

==========================================================================================

Starting Installation Process

If you have downloaded all necessary installation media as described in part 1(http://zieglers.wordpress.com/2009/11/10/sap-ides-erp-6-0-ehp4-netweaver-7-01-installation-guide/) and prepared your installation guest machine as described above, now we can start installing SAP IDES ERP 6.0.

… to be continued…

zieglers

Recently i was checking the posts I wrote about SAP IDES installation, and realized it’s been a while since I wrote the last one: http://zieglers.wordpress.com/2007/08/26/sap-r3-ides-47200-sr1-installation-on-windows-2003-r3-and-sql-server-2005/

Well, I think a brand new one is almost necessary: Here I give u, SAP IDES ECC 6.0 Installation on Windows 2003 with SQL Server 2008. I’ll try to explain the process with screenshots and try to keep it really simple. Hope it works!

=========================================================================================================

Step – 1: Download installation DVDs / files from SAP Service Marketplace:

Navigate to installation media

https://websmp101.sap-ag.de/~SAPIDP/002006825000000234912001E

Once you are at SAP Service Marketplace homepage, first click ‘Downloads‘ in first line navigation and then ‘SAP Installations & Upgrades‘.

1-)   2-)   

On the left navigation, select ‘Installations and Upgrades‘, then ‘SAP Application Components‘.

3-)    4-)

Then, select ‘SAP ERP‘, ‘SAP ERP Enhance Package‘ and ‘EHP for SAP ERP 6.0 / NW 7.01‘ respectively, as shown below. 

5-)  6-)  7-)

Since we’ll be installing IDES version, select ‘IDES-Version‘, and then ‘Windows Server – SQL Server‘.

 9-)

Download media for Export, SAP Installer, Java Component, UC Kernel and SAP GUI

Installation media necessary for SAP ERP 6.0 can be categorized in 5 main titles. This means once you start installing SAP ERP 6.0, SAP installer will ask you installation DVDs for 3 parts. Those are 1. Export DVDs, 2. Java Component, 3.Kernel. Additionally, you’ll need SAP Installer media itself and also SAP GUI. Now, let’s take a look which ones to download.

Export DVDs: You need to download 27 export parts named ‘IDES ERP 6.04/NW 7.01 Inst. Export‘. Once you extract those, there will be 4 DVDs, as shown below. Normal SAP ERP 6.0 installer comes with 2 export DVDs. Extra 2 DVDs result from the fact that IDES version includes many sample companies and related data to be installed.

Note from installation experience: Once installer finishes import jobs, you’ll have almost 160 GB sized database files and 10GB log file in total. No kiddin’! (See below)

Java Component: You need to download 4 parts for ‘NW 7.0 EHP1 SR1 Java based SW Components‘ as shown below. This will be only 1 DVD. Depending on your installation choice – ABAP vs. JAVA based – you might not need those during installation.

Also you need 3 parts BS Java components, ‘Java Comp. 7.0 SR1: ERP,CRM,SRM,SCM‘, as shown below.

SAP GUI 7.10: You need to download 2 parts for ‘NW 7.0 Presentation – 7.10 Compilation 4 Present.‘, as shown below.

UC Kernel: You need to download 1 part for ‘BS 7 SR1 UC-Kernel 7.01 Windows Server on x64 64bit‘, as shown below.

SAP Installation Master: You need to download 3 parts for ‘IDES Inst. Mst. 7.01: ERP, CRM, SCM‘, as shown below. This is basically our SAP NetWeaver Software Installer.

=========================================================================================================

This completes 1st part of this article – SAP IDES ERP 6.0 Installation – Gathering Installation Media. We’ll continue with installation environment in 2nd part of the article and start the installation.

If you didn’t recieve your installation media as DVDs, above mentioned approach was an alternate way to get your installation media. Hope this helps and let me know if you have questions.

Here is the 3rd part of the article – SharePoint Alerts Export Import add-in. I realized that it’s been a while that i wrote first and second articles. Taking a quick look at those, i see that “importing alerts” logic is left for this article.

Importing alerts can be done for a selected site collection and also individual subsites can also be selected explicitly. Alerts export logic was exporting all alerts of a site collection, not only root site, but also all subsites. Also those alert details were stored in an xml file in a structured manner. However, for import operation we need a selective import logic. Not all the time we might need to import alerts for a whole site collection. That’s why logic will be a little more complicated than exporting alerts.  

Moreover, an import operation can take some time based on number of alerts being imported and number of subsites exist. That’s why we need to have an SP Long operation so that user knows operation is being executed. Here there is a nice thing to note, that is, if user somehow closes the browser, import operation is not interrupted and goes on in the background until finished.Another important thing is the difference between type of alerts:  sp list alerts and search alerts. Although both of them are using SPAlert class, based on attributes being set a generic list alert can become a search alert. (p_query is the most important attribute for a search alert, basically which holds the query of the search alert)Here is a look how our Alerts Import application page ui is going to be like.   

After this intro, it’s time to get started.  Firstly let’s take a look at UI design. 

Alerts Import Page – UI Design

As for site collection selector seen above in first subsection of UI, we’ll use OOTB SharePoint SiteAdministrationSelector control. This control is frequently used in many application pages of Central Admin. Then, in order to list all subsites (in subsection 2) after a site collection is selected, we’ll have a CheckBoxList control. Finally, there is going to be a FileUpload control to select import file – the file which is exported using Alerts Export page. In addition, there is a “Verify” button to validate selected import file.  

SiteAdministrationSelector control 

<!-- *********************************************************
DISPLAY THE SITE COLLECTION SELECTOR USING THE InputFormSecton AND SiteAdministrationSelector CONTROLS. -->
<wssuc:InputFormSection runat="server"
   Title="<%$Resources:spadmin, multipages_sitecollection_title%>"
   Description="<%$Resources:spadmin, multipages_sitecollection_desc%>" >
   <Template_InputFormControls>
      <tr><td>
         <!-- Put your control here-->
<SharePoint:SiteAdministrationSelector id="SiteCollectionSelector" runat="server" OnContextChange="OnContextChange" /></td></tr></Template_InputFormControls> </wssuc:InputFormSection><!-- ********************************************************** -->   

<!-- **********************************************************
DISPLAY ALL SUBSITES USING THE InputFormSecton AND ASP:CheckBoxList CONTROLS -->
<wssuc:InputFormSection runat="server"
   Title="Web Sites"
   Description="Check web sites for which you want to import alerts" >

   <Template_InputFormControls>
   <tr><td>
      <asp:CheckBoxList ID="cbWebs" runat="server" CssClass="ms-listheaderlabel" EnableViewState="true"   />
   </td></tr>        
   </Template_InputFormControls>
</wssuc:InputFormSection>
<!-- *********************************************************** -->

FileUpload control for Alerts Import file and Verify Button
  
<!-- File name section -->
<wssuc:InputFormSection
    Id="SelectFileSection"
    Title="Select Alerts File"
    Description="Browse to the alerts file you intend to import."
    runat="server">
    <Template_InputFormControls>

        <wssuc:InputFormControl runat="server" LabelText="Name :">
         <Template_Control>
         <span dir="ltr"> 
          <asp:FileUpload ID="FileUpload1" runat="server" />
         </span>
         </Template_Control>
        </wssuc:InputFormControl>

        <wssuc:InputFormControl LabelText="Before importing, you can check this alerts import file for detailed errors, warnings, and other information." runat="server">
         <Template_Control>
          <asp:button class="ms-ButtonHeightWidth" runat="server"
           text="Verify"
           OnClick="ButtonVerifyClick"
           id="ButtonVerify">
       </asp:button>
         </Template_Control>
        </wssuc:InputFormControl>

        <wssuc:InputFormControl runat="server">
         <Template_Control>
          <div><asp:Label id="lblFileValidation" runat="server"/></div>
         </Template_Control>
        </wssuc:InputFormControl> 
    </Template_InputFormControls>
</wssuc:InputFormSection>

Alerts Import Page – Import Logic Design

So far, we have our UI elements ready. Now, let’s take a look at application logic. Almost all page logic is executed after user clicks ok button. Here is BtnSubmit_Click logic:

Basic validations

• Check if at least one web selected or not –> Display validation message if no web selected
• Check uploaded file –>Restrict the user to upload only .xml file

Preparations

• Assign import log file name and path
• Get url, port, virtual path details

Import Operation

• Read Alerts xml file for import operation
• Initialize date and alert count
• Iterate through each row of ‘Alerts’. This is also equivalent to looping through each web object.
  • Only import alerts for selected webs
  • Get alert property values from xml
  • Check Alert Template Type. This determines if an alert is a Search alert, List Alert, Item Alert …etc.
  • Create alerts

Alerts Import Page – Implementation

Basic validations

Before starting to import alerts, first we need to check alerts import file. Here we get some info about file using FileUpload control and only allow .xml files.

// Check uploaded file
if (FileUpload1.HasFile)
{
    // get the full path of your computer
    string strFileNameWithPath = FileUpload1.PostedFile.FileName;
    // get the extension name of the file
    string strExtensionName = System.IO.Path.GetExtension(strFileNameWithPath);
    // get the filename of user file
    string strFileName = System.IO.Path.GetFileName(strFileNameWithPath);
    // get the file size
    int intFileSize = FileUpload1.PostedFile.ContentLength / 1024; // convert into byte

    // Restrict the user to upload only .xml file
    strExtensionName = strExtensionName.ToLower();
    if (strExtensionName.Equals(“.xml”))
    {
        // upload the file on the server
        FileUpload1.PostedFile.SaveAs(AlertsDir + strFileName);

        strMessages += “Uploaded file details <hr />” +
            “File path on your Computer: ” + strFileNameWithPath + “<br />” +
            “File Name: ” + strFileName + “<br />” +
            “File Extension Name: ” + strExtensionName + “<br />” +
            “File Size: ” + intFileSize.ToString();
       
        // Assign Alerts File Path
        alertsFile = AlertsDir + strFileName;
    }
    else
        strMessages += “<br />Only <b>.xml</b> file is allowed, try again!<br />”;
}
else
    strMessages += “<br /><b>Select Alerts File: </b>You must select a valid alerts import file.<br />”;

Preparations

You can choose an import log file naming convention based on your needs. Here I used DateTime stamp.

// Assign import log file name and path

string logfile = logDir + “ImportLog_” + DateTime.Today.Day.ToString() + DateTime.Today.Month + DateTime.Today.Year.ToString() + “.txt”;

Import Operation

• Read Alerts xml file for import operation

// Read Alerts xml file for import operation
System.Data.DataSet ds = new System.Data.DataSet();

// Read selected alerts import xml file
ds.ReadXml(alertsFile);
ds.Locale = System.Globalization.CultureInfo.CurrentUICulture;

// Read xml document
System.Xml.XmlDocument doc = new System.Xml.XmlDocument();
doc.Load(alertsFile);

// Keep a list of selected webs in an arraylist
ArrayList selectedWebsList = new ArrayList();
foreach (ListItem item in cbWebs.Items)
    if (item.Selected)
        selectedWebsList.Add(item.Text);

• Initialize date and alert count and check datatable loaded by xml file.

// Initialize date and alert count
long AlertCount = 0;
DateTime start = DateTime.Now;
DateTime finish = DateTime.Now;

// Check if xml file has tables for alerts data
if (ds.Tables.Count < 2)
{
    LogMessageToFile(logDir + “ErrorLog.txt”, “Not a valid Alerts xml file”);
    strMessages += “<br /><font color=red><b>File Error: </b></font>Not a valid Alerts xml file! <br />”;
}

• Iterate through each row of ‘Alerts’. This is also equivalent to looping through each web object.
  • Only import alerts for selected webs
  • Get alert property values from xml
  • Check Alert Template Type. This determines if an alert is a Search alert, List Alert, Item Alert …etc.
  • Create alerts

Well at the moment…nothing is happening. But there soon will be.

I have just ordered an upgrade on the WAN (Wide Area Network). We will be using TPG and not Telstra to supply our internet and inter office connectivity.

What this means for you is that the days of frustrating slow connections, particularly using remote desktop access from Grimshaw street to Andrew Place will soon be over. I expect this new WAN to be implemented and running sometime towards the end of November 2009.

But wait…there’s more good news.

Upgrading the WAN is only one part of the solution. The next step is to upgrade the server at Andrew Place. The current server is old and knackered and ready to go to that great computer resting place in the sky. The shiny new super fast computer we are replacing it with will no longer clutter up the desk at the back of reception. All that “gubbins” will be removed and the server will be physically located elsewhere, maybe across the road at Grimshaw Street, or maybve even remotely at TPG’s data centre.

I am currently working on the specification for the new server and I hope to have the new server in place during December.

So what will all thgis mean for you?…Well it will make your life a lot easier. You will have fast reliable connections to our systems, and a fast reliable server. No more dropped connections, no more slow speeds, no more failing backups etc.

I am only “scratching the surface” at the moment of the advantages that our new IT system will bring…if anyone would like any more information, please, just ask me.

Virtualized systems are of two kinds. Software like VMware ESX Server, Xen hypervisor are first kind which directly runs over host machine hardware and the second kind runs over some host Operating System for e.g. VMware Workstation, Microsoft Virtual PC. The instance of operating system running is called the Virtual Machine (VM) and running multiple of them on host machine is called virtualization. These VMs share the same resources of the machine but are isolated from each other. Isolation of virtual machines is most important part in virtualization. Resource allocation is equally important and that marks the efficiency of such Virtual Machine Monitor or Hypervisor.

Nama Angry disematkan kepada software ini sesuai dengan pembuatnya, yaitu AngryZiber.  Software ini merupakan ‘pemain lama’ di bidang Security IT dan sudah banyak para ahli keamanan IT yg merekomendasikan software ini sebagai salah satu software penting yg wajib dimiliki oleh para system administrator di seluruh dunia.

Untuk lebih mengenal Software yg satu ini, saya akan coba kupas sedikit mengenai kemampuan software ini agar anda lebih familiar dan bisa mengexplore software ini lebih lanjut lagi. Untuk mendapatkan software ini, anda bisa mendowloadnya di AngryZiber / saya sudah membuatkan mirrornya di Indowebster. Perlu anda perhatian bahwa beberapa anti virus menganggap AngryIPScanner sebagai trojan, dan anda bisa melihat penjelasannya disini. Beberapa anti virus yg sudah saya test sendiri yg menganggap AngryIPScanner sebagai trojan adalah NOD32, Avast Home Edition, AVG Free, dan ClamWin. Ya maklum lah, saya memang dasarnya hobby untuk ngoprek-ngoprek software…

Oia, saya lupa menjelaskan kegunaan dari Software ini. Singkatnya Software ini berguna sekali untuk membantu anda menjaga, mengelola, dan menginventorisasi jaringan anda dalam hal ini IP Address ! Disini, saya mengambil sudut pandang anda sebagai system administrator. Alat ini sangat membantu anda dalam menghemat waktu dan pikiran anda ketika anda mengawasi jaringan anda dari tangan jahil yg terhubung ke jaringan anda. Ketika anda melihat ada alat (laptop / workstation / apapun itu) yg mencurigakan yg terhubung dengan jaringan anda, anda dapat langsung mengetahuinya sesegera mungkin ! It’s so nice, right ?? Try it, broder… Satu hal yg perlu diperhatikan sebelum menggunakan Software ini adalah anda harus paham dahulu mengenai konsep IP Addressing, karena ya itulah dasar dalam menggunakan Software ini ! Anda dapat belajar disini.

Setelah proses download selesai, langsung jalankan saja AngryIPScanner (tanpa proses installasi) dan akan muncul tampilan seperti screenshot berikut ini :

Angry IP Scanner

Berikut saya akan coba jelaskan bagian terpenting yg ada di AngryIPScanner :

• IP Range : di sini, anda HARUS mengisikan range IP yg ingin anda lakukan scanning ! Masukkan mulai dari range IP terkecil hingga range IP terbesar. Untuk belajar lebih lanjut mengenai IP Address, mulailah di Wikipedia / bertanyalah melalui Google.
• Hostname : nama dari komputer yg anda gunakan saat ini. Bila dari contoh di atas, Hostname komputer yg saya gunakan adalah Jonathan. Jadi Hostname akan berubah-ubah berdasarkan komputer yg anda gunakan. Untuk melihat Hostname komputer anda, gunakan cara berikut : klik kanan di “My Computer”, pilih “Properties”,  pilih tab “Computer Name”, carilah text “Full Computer Name” disitulah nama komputer anda.

Setelah, kalian mengisi kedua hal tersebut maka tekanlah tombol “Start” dan AngryIPScanner akan mulai bekerja. Berikut screenshot apabila AngryIPScanner selesai melakukan proses scanning IP Address.

Dari screenshot tersebut dapat disimpulkan proses scanning untuk range IP Address : 192.168.1.1 – 192.168.1.5 telah selesai dilakukan dalam waktu 11 detik, dengan kecepatan scan tiap host 2.200 detik, banyaknya IP yg di-scan adalah 5, dengan total komputer (host) yg menyala 2.

Perlu diperhatikan bahwa ada komputer yg secara realnya menyala, tapi tidak terdeteksi oleh AngryIPScanner bila komputer tersebut terpasang Firewall. Dimana Firewall akan memblok semua request yg dilakukan AngryIPScanner, sehingga seakan-akan komputer tersebut mati / tidak terdeteksi. So, demi keamanan aktifkan Firewall anda dan matikan service-service dari komputer anda yg tidak dianggap perlu !!

Dari screenshot diatas, untuk lingkaran yg berwarna biru berarti komputer tersebut aktif dan yg berwarna merah berarti tidak aktif ! Nah setelah kalian mengetahui komputer yg aktif, tinggal kalian yg menentukan apa yg hendak kalian lakukan dengan komputer tersebut.

Ingatlah, semua yg ada didunia ini bersifat netral hanya manusia yg memutuskan apakah itu baik / jahat ! So, seperti software ini (AngryIPScanner) bisa digunakan untuk kepentingan baik / jahat, semua tergantung dari siapa yg menggunakannya…

Sekian…

Lately I’ve been trying to install both windows [Vista and Win 7 Evaluation  RC1] and Linux [Redhat Linux] from USB flash drive. Booting and installing windows was easy as compared to the Linux part. It is making USB bootable about which I am talking. For this purpose a Transcend USB flash drive with  8 Gigs [8 GB] proved efficient, of course in speed, and handy rather than to use DVDs. And the chances that files get corrupt is very minimal. [ Why don’t these vendor’s provide OS in USB rather t

han in DVDs. I am optimistic.]

The first task I did was to make USB bootable for windows. To run both windows and Linux together, its recommended to install Linux at last. This will ensure us to boot cleanly with any OS we want. So I made my handy pen drive bootable. The process I did was…..

• Open command prompt in Win 7 [or Vista] with administrative privileges
• Following are series of command to make USB bootable for windows
  C:\……> diskpart
  DISKPART> LIST DISK     [For checking disk information]
  DISKPART> SELECT DISK 1   [disk 1 is USB Flash drive]
  DISKPART> CLEAN          [cleans the data but is optional]
  DISKPART> CREATE PRIMARY PARTITION   [create partition as primary]
  DISKPART> SELECT PARTITION 1 
  DISKPART> ACTIVE         [to make it bootable the partition should be marked as active ]
  DISKPART> FORMAT fs=ntfs       [format with filesystem as ntfs]
  DISKPART> ASSIGN         [assign the partition a drive letter]
• Rest was easy copying the contents of Windows [Vista/win 7] ISO image.  [I used virtual cd drive of ULTRAISO to mount the iso image for copying it]

For this to work, the system should be able to boot from USB ( well its a common sense, isn’t it? and all of us knows that ). Rest of the process for installing windows is easy. After installation has been completed there was some tricky steps though the process is simple. I must thank syslinux for providing us with such solution. Hats off guys!!! Downloading the file was very easy than to figure out how to work with it.

The zipped syslinux 3.83 contained a lot of files which we don’t need for this purpose. Two files ‘menu.c32’ and ‘syslinux.exe’ are the two files we need. We sure do need one more file ‘syslinux.cfg’ which I had to write myself since the zipped file was devoid of this. [ May be there is other way round, but I prefer this one since its eacy and costs less time and space.]. We need one blank USB Drive for this purpose. The last USB used is just fine for this. Remember, I made this USB bootable in windows environment.

The process is as follows

• Navigate to the folder containing syslinux.exe in command prompt in windows
  C:\syslinux_folder> syslinux.exe –am  H:    [drive letter H represents USB drive]
• Copy the file ‘menu.c32’ to thumb drive
• Initialization Ram Disk and Linux kernel image are also required. These files can be found in the linux ISO image.
  These files are kept as H:\boot\vmlinuz   and \boot\initrd.img
• Create a file syslinux.cfg in the root of USB Drive. This file looks like following [somewhat similar to grub.conf]
  DEFAULT menu.c32
  TIMEOUT 5
  LABEL RHEL 5.3
       KERNEL /boot/vmlinuz
       APPEND ro root=/dev/sda1 initrd=/boot/initrd.img
• Now its time to copy the RHEL Image ISO in the USB Disk. Unlike in Windows, the ISO should be present in the USB disk [no need to extract the file].
• After machine boots up it will ask for RHEL image file, the directory containing the image. Select the local harddrive and proceed with installation with ‘/’ as directory holding the image.
• Rest is all about installing the Linux.

Enjoy booting with USB.

Here is a little code snippet re custom metadata search using SharePoint Object Model. This code is just querying a predefined scope – MySearchScope - for custom metadata field – MyCustomMetadata. Search Criteria is passed from a text field named txtSearchCriteria.

There are couple of things to note here:

1. Make sure you created a Managed Property for your custom metadata in your SSP.

2. Make sure that your custom scope is configured properly. It’s good practice to have a separate content source assigned for your custom scope.

3. Make sure that your custom scope is Shared, compiled and ready to use.

4.Be careful with QueryText construction. Custom scope must be enclosed in ” ” in WHERE clause.

==================================================================================

DataTable queryDataTable = new DataTable();
SPSecurity.RunWithElevatedPrivileges(delegate()

{

using (SPSite site = new SPSite(siteUrl))

   {
      // Construct query object based on document number entered bu user
      // Create a new FullTextSqlQuery class – use property intializers to set query
      FullTextSqlQuery myQuery = new FullTextSqlQuery(ServerContext.Current)
      {
         // Construct query text
         QueryText = “SELECT Title, Rank, Size, Description, Write, Path, MyCustomMetadata FROM portal..scope() WHERE MyCustomMetadata = ‘” +  txtSearchCriteria.Text + “‘  AND  ( (\“SCOPE\“ = ‘MySearchScope ‘) )   ORDER BY \”Rank\” DESC”,
         ResultTypes = ResultType.RelevantResults
      };

      // execute the query and load the results into a datatable
      ResultTableCollection queryResults = myQuery.Execute();
      ResultTable queryResultsTable = queryResults[ResultType.RelevantResults];
      // Load table with results
      queryDataTable.Load(queryResultsTable, LoadOption.OverwriteChanges);

   }

});

Sometimes you might wanna assign item level permissions to a list item instead of using Elevated Priviliges block throughout the whole code. This might happen in case you need to temporarily give a user higher priviliges than she has.

Typical example would be to provide a site reader exceptional functionality on a specific list item. In this case you break role inheritance and give the permissions you want. Here is a little snippet for that:

======================================================================

RunWithElevatedPriv

 …using SPSite…
    …using SPWeb…

// Get current user obj
SPUser user = SPContext.Current.Web.CurrentUser;
// Get current user token
SPUserToken token = user.UserToken;
// Get current user principal
SPPrincipal principal = (SPPrincipal)SPContext.Current.Web.CurrentUser;
// Get current user role assignment
SPRoleAssignment RoleAssignment = new SPRoleAssignment(principal);
// Get Your Custom Role definition
int SiteContributorId = -1;
SPRoleDefinition RoleDefSiteContributor = new SPRoleDefinition();

foreach (SPRoleDefinition roleDef in web.RoleDefinitions)
   // Find Your Custom Role Definition id
   if (roleDef.Name == “Your Custom Role Name”)
      SiteContributorId = roleDef.Id;

if (SiteContributorId != -1) {
   RoleDefSiteContributor = web.RoleDefinitions.GetById(SiteContributorId);
   // Add Your Custom Role to role assignments
   RoleAssignment.RoleDefinitionBindings.Add(RoleDefSiteContributor);
}

if (!impersonatedListItem.HasUniqueRoleAssignments)
   // Break role inheritance
   impersonatedListItem.BreakRoleInheritance(true);

// Add Your Custom Role assignment to list item
impersonatedListItem.RoleAssignments.Add(RoleAssignment);

 // Update changes
impersonatedListItem.Update(); 

   …close using SPWeb…
…close using SPSite…

1) Nu folositi pagini de “welcome”

Splash pages are the first pages you see when you arrive at a website. They normally have a very beautiful image with words like “welcome” or “click here to enter”. In fact, they are just that — pretty vases with no real purpose. Do not let your visitors have a reason to click on the “back” button! Give them the value of your site up front without the splash page.

2) Do not use excessive banner advertisements

Even the least net savvy people have trained themselves to ignore banner advertisements so you will be wasting valuable website real estate. Instead, provide more valueable content and weave relevant affiliate links into your content, and let your visitors feel that they want to buy instead of being pushed to buy.

3) Have a simple and clear navigation

You have to provide a simple and very straightforward navigation menu so that even a young child will know how to use it. Stay away from complicated Flash based menus or multi-tiered dropdown menus. If your visitors don’t know how to navigate, they will leave your site.

4) Have a clear indication of where the user is

When visitors are deeply engrossed in browsing your site, you will want to make sure they know which part of the site they are in at that moment. That way, they will be able to browse relevant information or navigate to any section of the site easily. Don’t confuse your visitors because confusion means “abandon ship”!

5) Avoid using audio on your site

If your visitor is going to stay a long time at your site, reading your content, you will want to make sure they’re not annoyed by some audio looping on and on on your website. If you insist on adding audio, make sure they have some control over it — volume or muting controls should be made available.

20 years after the fall of the wall, the democratically elected German government has possibilities of surveillance, the East German state was only dreaming of.

Every phone call, every email, ever visited website – it’s all saved for 6 months and can be traced back. With regards to a crime and under judicial control? No, from every single web user, in advance, turning up side down the presumption of innocence. But it is all to our best and will never possibly used against us.

BB is BlackBerry. Apa itu BlacBerry dan ada apa dengan BlackBerry? Orang yang doyan ngikutin trend alias selalu up to date masalah trend masa kin pasti tidak asing sama ini barang. BlackBerry itu brand ponsel yang terkenal di Amerika sana. Kalau di Indonesia kebanyakan orang pake Nokia, Sony Ericsson, Motorola. Kalau di Amerika sana, BB ini jadi idola, karena tidak Cuma sekedar ponsel biasa, tapi BB ini juga bisa disebut dengan gadget maupun smartphone karena fiturnya dan aplikasi-aplikasinya yang menarik dan lengkap.

Begini sejarahnya BB. Pada tahun 1998 sebuah perusahaan dari Kanada yang bernama Research In Motion (RIM) mengenalkan BlackBerry sebagai telepon genggam, dimana mempunyai kemampuan menyampaikan informasi jaringan data nirkabel yang mengejutkan dunia kala itu. RIM menyediakan sistem operasi multi-tugas (multi-tasking operating system – OS) bagi Blackberry yang memungkinkan penggunaan secara intens dari sebuah alat. Hal ini dikarenakan terintegrasinya layanan email secara praktis (mobile email) atau lebih sering disebut dengan layanan push e-mail, yaitu sebuah layanan untuk memudahkan seseorang menerima e-mail layaknya SMS, sehingga orang tidak harus melakukan kegiatan ritual memeriksa e-mail, karena perangkat ini akan memberikan notifikasi jika ada e-mail yang masuk. Namun pada era itu, ditahun yang sama dimana para konsumen tidak begitu memerlukan perangkat mobile e-mail maka salah satu model pertama 850 tidak begitu berhasil dipasaran.

Setelah proses pengembangan yang terus-menerus akhirnya BlackBerry dengan sentuhan model lebih ke model seperti saat ini. Dimensi layar telah mengalami peningkatan dua kali lipat dan dapat menampilkan 6 sampai 8 baris kalimat sehingga lebih memudahkan dalam penggunaan penulisan serta membaca pesan yang disampaikan. Penambahan memori internal juga ditambahkan 2 kali lipat dari 4mb pada model sebelumnya menjadi 8mb yang terintergrasi didalamnya serta membenamkan memory dari 512KB SRAM (memory) ke 1 megabyte penuh. Fitur yang di unggulkan saat itu mampu untuk melakukan sync hingga 10 email pribadi maupun bisnis yang bisa di upgrade. Mulai saat itu RIM terus mengembangkan BlackBerry dari sisi teknologi serta modelnya yang akan berkerja secara jenius di masa depan.

Sekarang BB ini dijadiin model ponsel dimana-mana. Di iklan pake BB, di sinetron pake BB, artis-artis, anak-anak muda, businessman semua pake BB. Dan bahkan sekarang yang sangat marak adalah banyak bermunculan merk-merk ponsel replica BB. Mulai dari BB Bold, Curve, Tour, Javelin, Storm ataupun yang terbaru yaitu BB Gemini. Kalo harga yang legal masuk di Indonesia, harga BB di paling murah di atas 3 juta.

Once I get the new IT system instaled and working I will look at ways of imnproving our telephony sytem.

To give you a flavour of some of the possible changes afoot, the areas I am considering improving are:-

1. Creating and integratating an automatic SMS system, allowing Practice 2000, or whatever software we use, to send out automated SMS messages to remind poatients of their appointments. For our older patients who do not have mobile phones, the system can dial a land line number and play a pre recorded reminder message.

2. Implementing a VOIP (Voice Over IP) solution, which will enable calls between extensions at Grimshaw Street and Andrew Place to take place as though they were simply extensions on the same phone system. No more calling via reception…direct free inter office calls!

3. Implementing a “Call Routing” system, so that when people call we have an ifficient “Digital Receptionist” which will route calls to appropriate destinations, including an emergency response destination.

I have a lot more investigations to do on the phone system before any decision is made, but I wanted to let you know of the areas I am considering at the moment. Improving the nphone system is predicated on improving the IT systems, and this is my main focus at the moment.
