1、Bill Gates Keynote: Microsoft TecheEd 2008 DevelopersRemarks by Bill Gates, Chairman, MicrosoftMicrosoft TechEd 2008Orlando, Fla.June 3, 2008BILL GATES: Good morning and welcome to TechEd.This is the first year that we broke TechEd into two sections, the section this week, which is just for develope
2、rs, and a section next week, which is focused on ITWhe n we did that, we thought wed get about 4,000 developers to the con fere nee, and so weve been very pleased that theres over 6,000 people signed up and attending the events this week. So, a huge response, a lot of exciting new things that youre
3、going to get a chanee to see.I really enjoy comi ng to this con fere nee because Im a developer Writi ng code in new and better ways is really what drives the progress of our in dustry: the ability to develop new user in terfaces, the ability to connect up to all the sites out there on the Web, the
4、ability to let people view data in the way they want to view it.And development really is changing. The tools are getting better all the time.Today, were going to take a glimpse at the various aspects of that, and see what were doing, but, of course, the cen ter of this con ference is your opport un
5、ity to go to the breakouts and give us feedback and tell us what you like about what we*re doing, tell us what youd like to see us do differe ntly. We really value the great in teracti on that takes place at this eve nt.Well, for me this eve nt is also a milest one. Ifs my last public speech as a fu
6、ll-time chairma n of Microsoft. July 1 is when I make a change. Ill go from being full-time at Microsoft and part-time on the work of my foundation to doing it the other way around, full-time on the foundation and part-time with my Microsoft work.Now, thats the first time Ive really changed my caree
7、r since I was 17 years old and just completely immersed in software and the unbelievable ways that software, together with the microprocessor, has created new thin gs, in eluding the pers onal computer itself and the en tire Internet.So, I dont know what ifs going to be like It will be a bit abrupt,
8、 and put me in new territory. So, some friends called me up and said that to help me get in the mindset of what it would be like theyd help me put together a video of my last day and making this switch What we did here is we pulled together sort of a directors cut of this last day video with a fair
9、number of new things and some interesting things So, it should be fun. Lets take a look at what my last day might be like (Video segment)Well, we had a lot of fun making that, and the whole transition that was announced two years ago is going very well, and there are some incredible people, a number
10、 of whom will be on stage with me today, are steppi ng up to drive the tech no logy work.Changes in Technology: Hardware and Software AdvancesNow, this work is more ambitious every year. Developers can write applications that were not possible before Whats the reason for this? Well, theres really tw
11、o key things, one is the advanee in hardware, and the second is the advanee in the software platform. And we cant underestimate the important role that hardware improvement plays here. After allz we can add exponential improvement in the performanee of the microprocessor itself. The increasing clock
12、 speed has allowed it to do applicati ons that simply would nt have bee n possible in the past. The unb elievable amounts of storage we have today, meaning that databases that record every click for millions of customers, and get data mined for deep patter ns, those are now feasible on fairly low-co
13、st systems. And so the sky is the limit in terms of empowering people, and writing very rich applications.The microprocessor has gone through a lot of changes We went from the 16-bit processor with a meg of memory to the 286 that gave us a 24bit memory space, then to the 386 with a 32bit memory spac
14、e, and now were in the transition to 64bit And thats quite soon because that compatibility, the ability to run the existing applications is fairly straightforward, at the driver level we need a few changes, but this will be probably the simplest address space transition weve made.Looming after that,
15、 though, is an even more interesting challenge, which is the clock speed will not in crease at the same rate it has over the last 30 years It will largely stay the same, and the additional performanee will come from having multiple execution units. And so the need to take programs and break them dow
16、n into parallel execution units now becomes absolutely necessary to get the ben efit of the exp onen tial increase in tran sistors. We have an in credible amount of work at Microsoft to make the run times higher level, and to make it easy to take your code and write it in this parallel fashion. There will be a lot of discussion about this so-called ,multi-coren revolution in how we make sure were all doing the bes
