Aufzeichnung zum Oktober-TechTalk: Windows 7 – ein Überblick für Entwickler (Teil2)

Jan Schenk — Tue, 03 Nov 2009 18:32:00 GMT

Der Hauptfokus bei Windows 7 wurde auf die weitere Verbesserung der Sicherheit, Zuverlässigkeit und Performance des Betriebssystems gelegt - und auf die größtmögliche Kompatibilität zu Windows Vista , damit bereits bestehende Anwendungen auch in Zukunft laufen. Für Entwickler bietet Windows 7 viele neue Schnittstellen, um Anwendungen mit umfassenderen Funktionen zu versehen, die dem Endbenutzer eine neue Erfahrung im Umgang mit Software ermöglichen.

In dieser TechTalk-Aufzeichnung erklären Oliver Scheer und Peter Kirchner, wie etwa die neue Taskbar genutzt werden kann, indem die Preview-Ansicht gesteuert, Status-Informationen ausgegeben oder die Sprunglisten nach Ihren Wünschen angepasst werden können. Wir zeigen neue Möglichkeiten für die Anpassung von Windows-Diensten, um die Performance des Betriebssystems optimal zu nutzen und demonstrieren die Verwendung der in Windows 7 eingeführten Bibliotheken, um den Zugriff auf Dokumente Ihrer Anwendung zu vereinfachen. Zusätzlich erfährt man, welche Punkte zu beachten sind, um die Kompatibilität Ihrer Anwendung mit Windows 7 sicher zu stellen, wenn diese bereits auf Windows XP oder Windows Vista laufen. Abschließend wird ein Überblick gegeben, welche Änderungen sich im Windows Logo Programm ergeben haben und wie Sie Ihre Anwendung für Windows 7 zertifizieren lassen können.

Rico Mariani: Inside Visual Studio Beta 2 - Performance and Reliability

Charles — Tue, 20 Oct 2009 15:48:00 GMT

I caught up with the great Rico Mariani, Visual Studio's Chief Software Architect, after his keynote at a VS partner conference held on the Microsoft campus. He tells us all about the improvements in Visual Studio 2010 Beta 2. Rico and team have taken the performance and reliability of Visual Studio to new levels in this release. Gone are the days of synchronous assembly and COM component reference look-ups (woo hoo!!!). Gone are the long start up times. Gone are roughly 90% of the performance bottlenecks that slowed down the development experience inside the VS2010 Beta 1 IDE. The Visual Studio development team worked their tails off to improve perf and reliability across the board. Tune in to learn about what they did and what they will do prior to RTM. Truly excellent engineering goes on in building 42. Well done, team!

Rico also discusses his final blog post in his VS history series, a 5,000 word up to the minute historical piece. After watching Tina's great VS documentary series, Rico decided to add his own perspective in a 10 part blog post blitz. Great stuff!

Enjoy.

David Fields and Bill Karagounis: Inside Windows 7 - Reliability, Performance and PerfTrack

Charles — Mon, 10 Aug 2009 18:31:00 GMT

PerfTrack is the feedback and monitoring system inside of Windows 7 that performs measurements on, well, all things related to the overall performance of the OS, especially as it relates to system responsiveness to user actions. So, when you click on something (an icon, a folder name, etc...), how long does it take for the user to receive an expected reaction from the system? What are the bottlenecks that lead to a poor experience (user-observable latency) when using some feature in Windows? Is the root problem in the design of the feature itself or with the underlying OS? Enter PerfTrack.

Here, Development Manager David Fields and Group Program Manager Bill Karagounis share their wisdom and experience in the world of OS performance analysis. David and Bill explain how PerfTrack works and we digress into an interesting conversation about power management.

PerfTrack is an example of a technology that provides incredibly important real-world information to Windows engineers that can be used to solve performance problems in Windows.

Enjoy!

Michael Fortin: Windows 7 Efficiency

Charles — Wed, 22 Jul 2009 20:42:00 GMT

The Windows 7 project involved very efficient software engineering planning and execution. It is no surprise that an equivalent level of efficiency exists throughout the OS (efficiency in how the OS deals with faults, threads, memory management, power management, process management, window management, graphics, audio, local search, diagnostics, and on and on - truly excellent, and efficient, engineering).

Michael Fortin is a Distinguished Engineer in the Windows Core Operating System Division. His team builds the technologies that help make Windows 7 reliable, stable and performant, which are core ingredients in any highly efficient general purpose operating system. You'll hear us talk about Windows 7 as a very efficient general purpose operating system quite a bit over the coming months. In fact, if I had to sum up Windows 7 in one word it would be Efficient.

Michael's team also builds the troubleshooting and diagnostics systems in Windows, including the internal mechanisms that construct fault data packages and sends them to cloud-based components which receive data from millions of clients running Windows 7. Michael's team is a global team - engineers are located in multiple places around the world including a stellar team of engineers located in Beijing, China (you'll meet them in the future right here on C9).

You may remember Michael from his last interview on Channel 9 that covered his work on Vista's SuperFetch and ReadyBoost technologies. Yep, these great technologies are alive and well in Windows 7 and have evolved to meet the needs of the evolving system and help add to the overall efficiency of Windows. (There, I wrote "efficiency" again...)

Over the past year or so, Michael's team has received, analyzed and acted upon a very large amount of data sent from Windows 7 Beta and RC running on a variety of PCs with a variety of hardware and software configurations in place. This data was used to construct new system features, like the Fault Tolerant Heap, and to engineer updates to existing mechanisms to make them more robust or performant or reliable or stable... You will meet some of his team here on C9 in the future and we will dig into many of the mechanisms Michael touched on in this conversation (Fault Tolerant Heap, Troubleshooting and Diagnostics, etc).

Here, Michael and I chat about the work his team has done, the engineering philosophy that has driven efficiency into Windows at all levels (from the kernel to the shell), the knowledge his team has gained about how Windows is used in the wild, what the most common problems have been and the solutions that are based on this important telemetry data. So, for all of you out there who chose to send fault data from your PC to Microsoft - THANK YOU. You truly have helped, in a fundamental way, to make Windows 7 the most efficient general purpose operating system from Microsoft to date. Yeah. True story.

Enjoy.

Inside IE 8 RC1 with Dean Hachamovitch and Jason Upton

Charles — Mon, 26 Jan 2009 22:34:00 GMT

IE team General Manager Dean Hachamovitch and IE Test Manager Jason Upton sit down with me to discuss the significance of today's IE 8 RC1 release. What did the IE team learn from the Beta 2 release? What changes did they make in response to customer feedback? Will the IE team still take and act upon fedback now that RC1 is here? With so many browsers on the market today how does IE remain competitive and maintain marketshare? No conversation on IE can be complete, of course, without talking about the web platform and standards so we go there....

Of course, you can expect this discussion to continue at MIX09 (and you'll be a key participant in the conversation with Dean and team in Vegas).

See the IE Blog for more detailed info on what's in IE8 RC1.

Tune in. This is a great conversation with two key leaders behind and in front of IE (Dean is the all up team leader (as you know by now given how many times you've seen him on C9 and at various conferences) and Jason is responsible for overall product quality (he owns the stuff you seldom see or hear about - software testing)).

Gabriel Aul: N-State Chaos and Windows Performance

Charles — Mon, 18 Aug 2008 21:09:00 GMT

Gabriel Aul is a 16 year Microsoft veteran who has always had his hand in the chaotic world of system performance and reliability, from technical product support and testing to being a leader on the Windows performance team. In fact, he was part of the team that developed the original Watson failure reporting tool. He's a dev at heart (once a dev, always a dev) and understands the complexities of Windows as a platform: Windows supports thousands of devices and the thousands of drivers that make them useful to users (devices sometimes have more than one driver, so add that to the complexity quotient...). How can so many devices (drivers) work together successfully (meaning not hosing the system) with so many supported configurations and possibilities for drivers to bring Windows to a screeching halt (think about task scheduling, resource allocation, background processing, foreground processing user mode code execution, kernel mode code execution and the sheer amount of concurrent running code, all over the place, all contending for Windows' attention...).

The world of Windows as platform is incredibly complex (n-state chaotic). It's amazing, actually, that the chaos doesn't lead to more performance and reliability issues. The Windows performance team has some really powerful tools (and an effort called Velocity) that can help ISVs find highly complex performance issues. Gabriel touches on this in this conversation and we address the continued need for more guidance and samples for developers.

One thing is for sure: The developers who write applications and drivers for Windows are great developers. You are craftsman, artists. Windows is a great platform in many ways because of the people who innovate on top of it. You know who you are. Yeah, you. Thank you.
