The Eight Fallacies ofDistributed ComputingPeter DeutschEssentially everyone, when they first build a distributed application, makes the following eight assumptions. All prove to be false in the long run and all cause big trouble and painful learning experiences.1. The network is reliable2. Latency is zero3. Bandwidth is infinite4. The network is secure5. Topology doesn’t change6. There is one administrator7. Transport cost is zero8. The network is homogeneousFor more details, read the article by Arnon Rotem-Gal-Oz
The first listed usage of log-book or logbook is from roughly 1689 J. Moore’s New Syst. Math. By travelling back 250 years in time, we’ve gone from identifying ourselves within a computer system to entering the speed of a sailing ship into a book.

I still have my 1978 edition of The C Progamming Language on the shelf and will probably read it at least one more time.
Steve Jobs passed today and his history is the history of personal computing. I have been personally and professionally inspired by Apple products since I first got into computing. My Mac Classic was my first personal computer and my MacBook was my first laptop. A couple of years ago I returned to the Mac from many years in the land of Windows and it was like going home. Let’s all hope that Apple’s fine people can sustain the kind of innovation and inspiration that personified the company with Steve at the helm.
NEW YORK (CNNMoney) — For nearly three decades, personal computer makers thrived by building their PCs around two key ingredients: Intel chips and Microsoft Windows.
It’s an unprecedented success streak in the fast-changing tech market, where new technologies displace old ones in an eyeblink. But now, it looks like the “Wintel” party is finally winding down.
The Genesis of Adobe
In the beginning, Xerox PARC created the graphical desktop. The personal computer was yet formless and empty, and darkness was upon the face of its software development. And then the money of Xerox moved to and fro upon the waters of innovation and PARC said, let there be icons and windows and Ethernet and SmallTalk object oriented development. And lo, there was a $15,000 workstation, and Xerox saw the Alto, and that it was good.
And then Steve Jobs saw the Alto, and he convinced Xerox to invest a million dollars in Apple. And Jobs said that Apple would commercialize Xerox’ technology and make the company rich on its investment. And thus Apple created Macintosh, which then attracted engineers from Xerox who joined Apple in order to work on products that might actually turn into something a person might actually see in the real world and not just in a PARC lab.
