I am working on a project and part of the instruction goes like this: "The whole system allows up to 10 processes currently stay in memory, only one of them is running on the CPU, while the others are in either the Ready Queue or blocked in the Disk queue. Each process has its PCB" I have been able to create 10 processes and they are running fine. I'm trying to write the code for the Ready and Disk queue and I'm running into a few difficulties. Below is what I came up with. I tried writing two functions for …

I have an interface built in javafx but it currently does nothing it just looks nice. How do you download files from the web in javafx or java? How do you create files on the users system in java or javafx? How do you place downloaded files in the created files? How do you call operating system file browsers in order for the user to choose the install location? Any help would be great. Thanks.

There's a lot of buzz on the Internet today about some "leaked" [URL="http://www.microsoft.com"]Microsoft[/URL] slides concerning Windows 8. But, like the [URL="http://www.computerworld.com/s/article/9178753/_Don_t_get_excited_about_Windows_8_says_analyst"]Computerworld article[/URL] on the subject says, you shouldn't get excited about anything in those leaked slides. You're likely to end up disappointed. If any of you can remember back to 1994, when Windows 95 beta versions were out, there were some awesome options available that never made it into the operating system (OS). In fact, some of them have never made it into any Windows operating system. Every new iteration of a Windows operating system brings out the wishers and …

As is to be expected as we fast approach the official launch of [URL="http://www.daniweb.com/blogs/entry4050.html"]Windows 7[/URL], more changes from the [URL="http://www.daniweb.com/blogs/entry3766.html"]Beta version[/URL] to [URL="http://www.itwire.com/content/view/23795/53/"]Release Code[/URL] functionality have been [URL="http://blogs.msdn.com/e7/archive/2009/03/13/a-few-more-changes-from-beta-to-rc.aspx"]confirmed[/URL] by Microsoft.

A lot has been said across the web about how this will affect Microsoft's market share. My own view is we'll see.

It's probably a little early to be looking for implications of Oracle buying Sun (no, it's official, here's the [URL="http://www.oracle.com/us/corporate/press/018363"]press release[/URL]). They've only just confirmed it's happening, and as one of the journalists who covered Novell buying Lotus many years ago I can confirm things aren't done until they're done, frankly. A few things spring to mind, though. First there will be much talk of useful synergies between the two. Second, there will be a strong company coming out of this. That aside, however, there will be more. First it's almost certainly going to be seen as a blow to …

Steven Sinofsky, the Senior Vice President for the Microsoft Windows and Windows Live Engineering Group, in an attempt to quell a beta tester rebellion over a perceived lack of feedback concerning bug reporting has made an astonishing confession: Windows 7 has at least 2000 bugs. Sinofsky [URL="http://blogs.msdn.com/e7/archive/2009/02/25/feedback-and-engineering-windows-7.aspx"]states[/URL] that more than a million people installed and used the [URL="http://www.daniweb.com/blogs/entry3766.html"]Windows 7 beta[/URL] in the first few weeks of release, and admits it has been a lot of work coping with the feedback.

Linux may never gain widespread success, that we, the Linux fans want it to, because it's just too complex for the average computer user. Sure, we now have [URL="http://www.kde.org"]KDE[/URL], [URL="http://www.gnome.org"]GNOME[/URL], [URL="http://www.xfce.org"]XFCE[/URL], and other fancy graphical user interfaces that attempt to mimic [URL="http://www.microsoft.com"]Windows[/URL] and the [URL="http://www.apple.com"]Mac OS[/URL] but underneath the shimmering polish, it's Unix and that scares people.

Ah yes, another significant victory for Linux as the Russian government [URL="http://www.russiatoday.com/news/news/22094"]decides[/URL] that there will be a national operating system based on Linux. This new operating system will be deployed in Russian schools sometime this year. The Russians plan to rid themselves of the capitalist opression of Microsoft--or something like that. Russia isn't the first country to make this decision as some schools in India, France, and the U.S. have already made the switch to Linux. The main reason they're switching? To save those Rubles, baby. I guess schools face tight budgets everywhere. This mass migration to Linux fulfills my …

According to the [URL="http://marketshare.hitslink.com/operating-system-market-share.aspx?qprid=8"]latest figures[/URL] just published by Net Applications, a specialist Internet measurement company, Apple has seen Mac OS X grab a record gain taking it dangerously close to a 10 percent market share for the first time since the company started tracking OS usage. In stark contrast, however, Microsoft saw a drop in the market share reported for the second month running, close to a full percentage point in fact. Indeed, the Net Applications numbers have it at an all time low now. Linux, meanwhile, continues to go nowhere fast. It seems to have somewhat stagnated in a …

So today, according to Tuesday's announcement, there will be new iPhone software available from Apple. We don't know exactly when, in the UK at 1.20 it wasn't there, but no matter - it's going to arrive. And it's going to address issues a few users have noticed, specifically poor battery life and dropped calls. Hold on. A phone that drops calls. A phone which - as I've found a few times - lasts less than a day if you have location services switched on and particularly if you have the brightness turned up on the display. Yes, you can work …

Google started out as a Search Engine, Their next big step was announcing Android Their new Mobile Operating System, and then their browser Chrome.

Details of a future Microsoft operating system were revealed yesterday by David Worthington, a guy who works down the hall from me. He has apparently gotten his eyes on Microsoft documents that contained extensive details of a ground-up OS rewrite code-named Midori. Based on those documents, [URL=http://tinyurl.com/5ryum5]he reports[/URL] for SD Times that Midori "will have a programming model, a platform stack and execution techniques that are intended to help developers write applications that can safely and efficiently use a greater number of hardware threads than is currently feasible," Worthington wrote. Midori's lowest level consists of a hardware-native kernel. A second, …

The conclusion being that unless something is done soon then it is only a matter of time before a competitor that is more able to tackle the problems it has faced will emerge and dethrone the OS King. The analysis, carried out for Gartner by Michael Silver and Neil MacDonald, included a survey which asked if Microsoft needed to radically alter its approach to Windows to stay viable. Of the assorted IT managers and executives questioned, half apparently raised their …

The French parliament is now going to dump Windows in favour of open-source. More specifically, Linux. The planned switch date is June 2007, with over 1000 parliament workers switching. No word yet on what Linux distribution they're going to use, or what email client -- one thing is for sure: they're going to use Firefox as their web browser. At the moment, a number of the computers run Linux, using Apache as their web server, and a content-management system being run with [URL="http://www.mamboserver.com/"]Mambo[/URL].

Launched September 5, 1977, the Voyager 1 spacecraft has crossed the Termination Shock* of our solar system, and has entered a new region of space at extreme distances from our sun. According to researchers at the University of Maryland, Voyager made this transition December 16, 2004, and it took researchers several months to track the latest data and confirm that the explorer made the transition. Voyager will need to travel through the Heliosheath*, pass through the Heliopause*, and then it will be in pure interstellar space, and completely out of the solar system.
