Instalasi Windows 7 di Flash Disk

Untuk menjalankan tutorial ini anda membutuhkan:
- USB Flashdisk, berkapasitas minimal 4GB
- File installer Windows 7 atau Windows Vista (kami tidak merekomendasikan file bajakan)
- PC dengan DVD/CD-ROM (bukan netbook)

Untuk menginstall Windows 7 dari USB Flashdisk, kita harus mempersiapkan sang flashdisk sendiri dengan langkah-langkah berikut:

1. Colokkan flashdisk dan backup seluruh data yang ada ke tempat yang aman.

2. Buka Command Prompt (cmd.exe) dengan wewenang Admin. Contohnya, klik Start Menu -> All Programs -> Accesories, klik kanan pada Command Prompt dan pilih Run as Administrator.

3. Ketahui info USB Flashdisk dengan perintah DISKPART. Kemudian ketik perintah LIST DISK untuk mengetahui penomoran Disk dari USB Flashdisk tersebut.

4. Jika diasumsikan, flashdisk berada dipenomoran Disk 1, maka tulis dan eksekusi perintah berikut:

SELECT DISK 1
CLEAN
CREATE PARTITION PRIMARY
SELECT PARTITION 1
ACTIVE
FORMAT FS=NTFS (tunggu proses format yang memang agak lama)
ASSIGN
EXIT

Sampai ke langkah tersebut, jangan tutup prompt, tapi cukup minimize saja.

5. Masukkan CD/DVD instalasi Windows 7, kemudian ingat huruf kandar dari media optik tersebut, misalnya DVD di “D” dan flashdisk di “H”

6. Maximize lagi prompt yang kita minimize pada langkah 4, kemudian tulis perintah:

D:CD BOOT dan tekan enter, dengan catatan D adalah huruf kandar DVD anda.
CD BOOT dan tekan enter

7. Instalasi Bootmanager ke USB Flashdisk dengan menggunakan perintah:
BOOTSECT.EXE/NT60 H: dengan H adalah huruf kandar USB anda.

8. Tinggal copy semua isi DVD instalasi ke USB Flashdisk
9. USB Flashdisk sudah dapat diboot dan menjalankan instalasi Windows 8. Yang tentu dibutuhkan adalah mengubah parameter awal boot ke USB dari HDD atau CDROM.

Membuat Form Koneksi Database dengan VB 2005

Untuk membuat suatu aplikasi agar bisa dijalankan pada sebuah jaringan diperlukan sebuah form koneksi agar programmer tidak perlu lagi membuka source code aplikasi untuk merubah Connection String-nya. Hal ini sangat berguna jika aplikasi dijalankan pada komputer yang berlainan dengan database. Berikut ini saya membuat form untuk melakukan koneksi ke-database SQL Server 2000 dengan menggunakan Visual Studio 2005 dan koneksi yang dibuat disimpan pada file notepad dengan extention ".ini". Dalam hal ini saya juga menggunakan module agar bisa diakses disemua form nantinya.







Berikut source code-nya :

Review Norton Internet Security 2010

Memilih antivirus hari-hari ini butuh kejelian. Tidak semua antivirus punya kemampuan yang sama. Ada yang piawai dalam membasmi virus tertentu, ada yang hanya mampu mendeteksi virus lokal.

Namun untuk membantu mengerucutkan pilihan dari deretan produk antivirus, disarankan untuk menengok review dari lembaga pengujian independen, seperti AV-Comparatives.org. Nah, untuk urusan deteksi ancaman, tiga lembaga uji independen – AV-Comparatives.org, AV-Test.org, dan Dennis Technology Lab – sepakat untuk menunjuk produk keamanan Norton, termasuk yang berbasiskan teknik Quorum, sebagai efektif memberikan perlindungan.


Dennis Technology Lab yang menguji efektivitas 10 produk keamanan saat membandingkan anti-malware menyebutkan Norton Internet Security 2010 tampil sebagai satu-satunya produk dengan deteksi sempurna” dalam menghadapi seluruh ancaman dan sepenuhnya melindungi sistem dari serangan atau infeksi.


Norton Internet Security 2010 juga dicatat oleh AV-Test.org yang melakukan uji di PC yang terinfeksi 25 sampel malware yang berbeda sebagai berhasil mendeteksi dan menghapus semua infeksi.

Sementara itu Norton AntiVirus 2010 diganjar rating “Advanced+” (tertinggi untuk perlindungan) oleh AV-Comparatives.org dalam Anti-Virus Comparatives Test No. 23. Symantec juga menerima rating “Fast” tertinggi untuk kecepatan scan.


“Seluruh pengujian tersebut mencakup benchmark-benchmark penting tapi sangat berbeda dalam pengujian keamanan. Namun semuanya sampai pada kesimpulan yang sama—Norton adalah penawaran terbaik di kelasnya,” terang David Hall (Consumer Product Marketing Manager, Asia Pacific, Symantec). “Produk-produk Symantec dengan teknologi keamanan berbasis reputasi kami yang baru dan heuristics canggih, menunjukkan kemampuan mereka dalam memberikan perlindungan terhadap jutaan ancaman dengan menjaga tingkat false positive paling rendah dan kinerja tertinggi di seluruh produk yang diuji.


Beberapa produk Symantec yang berteknologi Quorum adalah Norton 360 version 4.0 beta, Norton Internet Security 2010 dan Norton AntiVirus 2010.

Vista SP2 and Windows 7 by the End of June 2009

The evolution of the Windows client, involving both Windows Vista (now with Service Pack 1) and Windows 7, appears to be closer than Microsoft is ready to acknowledge officially. Of course, Windows XP, even with Service Pack 3, is the past, with the exception of customers abandoning Windows Vista by exercising their downgrade rights. Windows Vista, even with SP1, is a present that makes the future seem to not get here fast enough. And Vista SP2 along with Windows 7 and Windows Cloud (Strata) are the future. But at the same time, both Vista SP2 and Windows 7 are nothing more than the evolution of Vista, to a lesser, and respectively a larger degree.

Come the end of October 2008, and the start of November, Microsoft will deliver a rather consistent taste of where it is heading with Windows, not only Windows 7, but also Windows 7 Server and Windows Strata (the label continues to be unconfirmed by the company). Events such as the Professional Developer Conference 2008, Windows Hardware Conference 2008 and TechEd EMEA will be focused on Windows 7 and Windows Cloud, although less on Windows Vista.

While at TechEd Brasil, at the start of this week, Microsoft Chief Executive Officer Steve Ballmer indicated that the company planned to unveil a range of new products by July 2009. Microsoft's CEO mentioned that, by the end of June 2009, the software giant would offer "client operating system releases." Microsoft is, of course, already cooking Windows Vista SP2 and Windows 7.

Ballmer stated that "Microsoft technologies: Windows, Windows Server, .NET, Visual Studio, Silverlight, SharePoint, Office (...) over the course of the 12 month period that ends June of next year, [are] just a subset of all of the exciting new innovations Microsoft will bring to market: client operating system releases, information management tools, security, gaming products and systems. The range of new technologies in some senses is growing and growing quickly." (emphasis added)


Windows Vista Service Pack 2 (SP2)

Microsoft released Windows Vista RTM at the end of January 2007, not counting the business launch of the operating system in November 2006. Vista SP1 was released to manufacturing on February 4, 2008 concomitantly with Windows Server 2008, but was only made available for download starting March 18. Now the Redmond company has already moved onward to Service Pack 2.

In fact Vista SP2 invites to the Beta program have already started to be sent out, according to Neowin. It is not Windows Vista SP2 that Microsoft is cooking, but also Windows Server 2008 SP2, Beta invites for which have also been sent out. Microsoft has yet to confirm anything officially, but the first Beta bits for Windows Vista SP2 and Windows Server 2008 SP2 are reportedly going to testers in just four weeks.

Still, while Service Pack 1 was the catalyst that took Vista RTM out of coma, making the operating system worthy of a long forgotten and discarded Wow label, SP2 is bound to be nothing more than a standard service pack release. At best, SP2 will take Vista forward just as much as SP1.

The equation is rather simple for Microsoft. The company will end up with a repeat of the Windows XP SP2 – Windows Vista scenario in which both operating systems are available at the same time on the market, although this situation would involve Vista SP2 and Windows 7 RTM. The last thing that Microsoft needs is to evolve Vista with SP2 sufficiently enough that it will be capable to rival Windows 7. In this context, the answer is rather simple. The Redmond giant needs to keep Vista at a relative stand-still even with SP2, and focus all innovation on Windows 7.


Windows 7, or Windows 6.1, or Windows Vista R2, or Windows Vista but "a lot better"

The seventh major version of Windows, but only according to Microsoft's math, comes with no differentiation between the codename and the brand. However, Windows 7 will, for the sake of perpetuating the existing level of Vista software compatibility, be in fact Windows 6.1. At the same time, according to Ballmer, Windows 7 will be Vista, but “a lot better.” This makes Windows 7 an excellent candidate for the Windows Vista R2 label, just as Windows 7 Server is in fact Windows Server 2008 R2. Still, the early feedback on the Windows 7 moniker indicates that the management of the Windows 7 project made the right choice.

"There you have it, Windows 7 now has a name. It’s called – Windows 7,” revealed Steve Clayton, Microsoft's UK Partner Group CTO. “To be honest I was quite surprised but also pretty pleased. The naming decision as Mike Nash says is about simplicity. It’ll certainly save us from all having to unlearn the name we’ve all had for it to date. I expect this naming decision will be debated to death on all the usual sites, but me, I’m just happy we settled on a name. Now let’s get to the PDC and get the bits!"

"Win7 to officially be called . . . Win7" said Robert Hensing, Microsoft security software engineer. "I actually for once - LOVE that we are keeping the name of the OS simple and leaving it at Win7. I will admit – I was somewhat disappointed when XP's name was announced internally (internally it was known as Whistler) and I was downright horrified when we decided to call Longhorn "Vista" (my friends call it "Veesta"). Longhorn sounds cool . . . manly . . . Vista is pretty much the exact opposite in my mind . . . it sounds serene and 'pretty'."

"Steve Ballmer was at Gartner's Symposium/ITxpo conference today, talking about a number of issues. The big question was about Vista deployments and what should companies do. He answered by saying that the adoption rate for Vista, is two times that of where XP was after the same period," stated Neil Hutson, Microsoft evangelist. "Then in Jedi style, Neil MacDonald from Gartner said that 61% of respondents are thinking of skipping Vista. To that, Ballmer said that Microsoft would be ready for that outcome, but if he was the audience, he would not wait. I think that this is a good call. Vista SP1 is really stable and the big question is whether companies are going to wait for the first SP of Windows 7 before they deploy? That will leave them with a lot of very outdated machines and OS software that will take them a lot longer to replace."


Windows Cloud – To Strata or not to Strata?

At PDC2008 Microsoft plans to unveil the first Beta of Windows Cloud, which could be labeled Windows Strata, although the company has yet to confirm this aspect. Windows Strata goes beyond the Windows client and server operating systems, and is a new platform tailored to the Redmond giant's Software plus Services business model.

"We have our Professional Developers Conference in Los Angeles in a couple of weeks, we're going to roll out new technologies and a new platform for this software plus services world. The new platform has a lot of work to do. First, it requires a new platform in the cloud. In the Microsoft kind of way of thinking every new major trend requires a new version of our operating system. So, we did Windows, then we did Windows Server, then we did Windows CE and Mobile. And you'll see us bring Windows technologies in a new form to the cloud," Ballmer explained.

Microsoft is essentially looking to keep up with the changes associated with the development paradigm. But what the company is doing is transition the Windows style of development to the cloud and make it available in the browser. Silverlight, .NET, Windows Presentation Foundation and Visual Studio will all contribute to enabling developers to built web-based solutions running on Microsoft's new Internet platform. In this regard, the software giant is working to ensure that services will "be available as a system construct in Windows Server, in Windows desktop and in Windows in the cloud," Ballmer stated, adding that "with this evolution to a new world of distributed computing, we Microsoft will introduce a new cloud platform, some new cloud services around Web 2.0, some advances to our development tools and development runtimes, as well as tools and technologies that really support new business models."
