Are you looking for a more effective approach to real-time systems development? Real-Time Object-Oriented Modeling The development of real-time distributed systems is one of the most difficult engineering problems ever faced, taxing the capabilities of traditional real-time software development approaches. Real-Time Object-Oriented Modeling is the first book that brings together, in a single harmonious approach, the power of object-oriented concepts tailored specifically for real-time systems, with an iterative and incremental process based on the use of executable models. Developed by practitioners, the proven methodology described here is becoming a leader in the industry. Using a learn-by-example approach, this book offers:* A single consistent set of graphical modeling concepts, chosen to improve developer effectiveness, which apply uniformly to analysis, design, and implementation. This reduces the learning curve to master the entire method and eliminates expensive discontinui

| 10 of 10 people found the following review helpful  ROOM is great, the book is hard to read, By Miklos Nemeth (Helsinki, Finland) - See all my reviews This review is from: Real-Time Object-Oriented Modeling (Hardcover) It's very difficult to evaluate the book. There are actually two things to evaluate: (1) the ROOM methodology, and (2) the book publishing ROOM. The ROOM methodology is great: the only complete software development methodology I have ever seen. However the way it is discussed in the book is not an easy reading, even not for an experienced OO developer. Do not give up when you think you have lost. Reread sections until you understand the gist. Eventually, you will be very happy with the new tecniques you learned. I'm quite sure that ROOM is applicable not only for real-time systems. It should be adapted to non-realtime development too. Without reading this book you will not understand UML RealTime implemented by Rational RoseRealTime. My five stars are primarily for ROOM methodology. 3 of 3 people found the following review helpful  Useful, but mostly as a historical document, By This review is from: Real-Time Object-Oriented Modeling (Hardcover) First, remember that this book was published in 1994 - it was probably written in the 1992-3 era. The OO design world was still in the "warring states" period before unification under UML. The company that created ROOM tools, if I understand correctly, was absorbed by another company that was absorbed by another company - I'm not sure how much of ROOM in its pure form is still left.That doesn't matter. In its time, ROOM was wild, innovative, and a topic of heated debate. It created a visual, highly abstracted language (back then, a questionable novelty) around an intensely parallelized model of computing (also a questionable novelty), at a time when "real-time" often meant lots of assembly programming in command-line environments. I was doing embedded development back about then - based on the mind-set of the time, I'm surprised that ROOM had the success and influence that it did. Surprised but pleased. Lots of the ROOM techniques and notations survive in UML and other development tools. Modern component programming environments, JavaBeans included, show many signs of direct descent from the ROOM techniques. Still, there's a long way to go. ROOM may have been way ahead of its time, and languages still haven't caught up fully to its models of communication and parallelism. As impressive an achievement as ROOM was (and is), I have some reservations about it. It relies pretty heavily of state machines for modelling the interacting components. State machines are a good tool, but quite unfamiliar to most software developers these days. I'm not sure whether that's a fault of the methodology or of today's programmers. I also have reservations about any methodology that requires me to buy someone's tools. The authors state that the design methodology can be used without their tools - based on ROOM's complexity, I doubt it. Also, I have a serious distrust of any programming environment that takes over so much of the process. Such tool sets tend to leave me feeling cramped, with little way to express my ideas in different terms. Finally, I'm sure it does all it says it does. Even so, the moment always comes when the tool-generated subsystems need to be opened up for debugging, or when the system has to be open to interaction with other development tools. Real-time and embedded systems tend to be so idiosyncratic and demanding that both kinds of openness in an IDE are compulsory. I just don't see the way out of the closed ROOM. My present interest is not so much in the ROOM methodology itself, although I'm interested in methodology in general. Instead, I'm studying the visual notation it developed for expressing complex computations. Whatever ROOM's faults and whatever its later history, it's still worth attention. 4 of 5 people found the following review helpful ROOM represents the future of distributed sys. development, By A Customer This review is from: Real-Time Object-Oriented Modeling (Hardcover) The ROOM methodology (and ObjecTime's supporting toolset) is representative of the future of distributed system development. The underlying concept of concurrently executing, communicating finite state machines is the essence of successful distributed architecture design. ROOM does a quite reasonable job of mapping this concept into an object-oriented framework, and ObjecTime's toolset makes learning ROOM (and CCFSM) quite approachable-- dare I say even enjoyable!If you have any interest in distributed systems architecture at all, this book is a must-read. |

| 72 of 75 people found the following review helpful So far So good, By Antman "T2" (Brooklyn , NY) - See all my reviews Amazon Verified Purchase(What's this?) This review is from: Dell Inspiron M5030 2800B3D 15.6-Inch Laptop (3D Black) (Personal Computers) I got this laptop recently, why the 5 stars? Because its Functional for my needs. Most Important Specs are:-Windows 7 Home premium, AMD Athlon Dual-Core 2.30GHz,4.00Gb RAM,320 GB Hard Drive,4.1 Overall windows Experience Index. This is NOT a laptop for Gamers, or persons who want to run applications like AutoCAD, ARCGIS, or Adobe Photoshop, Why? because the processor is a Dual-Core its wayyyy behind in today's terms. This is a great laptop for young children, university students (those who are serious about schoolwork and dont play games like HALO,Dragon Age etc. lol) I use it for checking my emails on the go, and for typing reports and my occasional chess game. Other specs are listed on this page (scroll up). It has a nice patterned finish and comes with built-in wi-fi and a dvd burner. I will update further as i monitor the performance and durability of this laptop. **UPDATE** 22nd June 2011 I have decided to give a 3 month update. The laptop still continues to perform well. No noticeable cracks (as yet) on chassis as is customed with SOME DELL laptops especially around the corners (my DELL Inspiron 6400 has cracks). Yes it has no HDMI,no bluetooth a downer but not critical features to me. Some reviewers have misconceived my opening statements, I never said you cannot play games on this laptop, I'm saying that given the laptop hardware specifications certain applications (listed above) and games (not going to list too numerous) will either not run or run with slow frame rates especially newer titles.I use Autocad and ArcGis and when working on rendering 3D drawings (AutoCAD) or Queries for Analysis (ArcGIS) the laptop freezes but these are huge files.Your experience may vary depends on your type of usage. One commenter made the point about the memory, its stated that the laptop comes with 4 GB installed DDR3 RAM (1333 MHz, 2 DIMM slots). Yes it comes with 4GB, however in the BIOS the frequency of the memory is 1066Mhz. Now some might say that this can be changed by doing this or by doing that, that's not the point (it cannot be changed by the way the fields are read-only) its advertised as 1333 it should come that way. Keyboard shows no signs of fading but sometimes i get delayed keystrokes could be software related though. In summary still a good buy (I paid 399.99),I have no regrets with this purchase SO FAR. 35 of 36 people found the following review helpful Nice features for the price, By Celine Chamberlin (Oregon, USA) - See all my reviews Amazon Verified Purchase(What's this?) This review is from: Dell Inspiron M5030 2800B3D 15.6-Inch Laptop (3D Black) (Personal Computers) I bought this laptop on sale recently, and so far, I have no real complaints. Set up was simple and fast, and it connected right away to my WiFi. It's obviously not a gaming machine, but I installed some of my favorite (though not current) games (Portal, Half-Life 2: Episode 1 and 2), and they run just fine. Overall, it works as advertised, and for the price, I don't have any serious complaints.The "3D" finish might not appeal to everyone, but I like it. It hides fingerprints very well, and it plays with light in a nifty way. I haven't had any reason to use the webcam, but did test it to make sure it works. It's low-res, but good enough for basic things like chatting. The software dock in Windows is a nice touch. Pros: a nice bright display (I actually had to turn it down a bit), a roomy keyboard (I consider the lack of a number keypad a definite plus), and Windows 7 64-bit Home runs very fast. Cons: no HDMI port (it has VGA), plastic case feels a bit flimsy, and the speakers are rather tinny. These cons are minor, in my opinion. Bloatware wasn't too much of a problem, either (I uninstalled only a few things). I do wish the memory card reader included CompactFlash for my older DSLR camera, but that's just a personal preference. Most devices don't use this type of memory card anymore. Other notes: all the various ports are on the left side of the machine (one of the USB ports is at the very front of that side, which might get in the way for some), the DVD drive on the right, the memory card reader on the front, and nothing but the battery compartment on the back. 23 of 24 people found the following review helpful  M5030 Dell, Amazon Verified Purchase(What's this?) This review is from: Dell Inspiron M5030 2800B3D 15.6-Inch Laptop (3D Black) (Personal Computers) Good value at 9 my sale price. I found it fast but heavy and upgradable. The "3D" finish is not attractive to me but will prevent fingerprints. I needed this laptop to run VMs for demos and development and this was in my price range. I found that the memory upgrade to 6GB was no problem() and keyboard removes ok for the memory access. Windows anytime upgrade got it to Windows 7 Pro for . Right now it is running an XP machine in virtual-pc and a 2008 server in virtualbox but having trouble running both at same time. The dvd writter works great and 3 USB 2.0 ports are handy. The wireless network is g and wired is 10/100 not 1000. I think networking could be better and the other external port is only vga should maybe be hdmi |
