During the course of the past week, there's been an increasingly lively discussion (and debate) about the real-time characteristics of Linux, and over which approach is best. As a result, questions like these are starting to become more and more common . . . What does "real-time" mean? Who (or what) needs real-time, anyhow? How much real-time is really needed? What are the alternative ways to add real-time to Linux? In this article, we'll try to clear away the smoke, and provide some perspective on the subject of real-time Linux. Here's the plan. First, we'll define terms like real-time, hard real-time, soft real-time, and learn how real-time performance is characterized. Next, we'll learn what sorts of systems need real-time, and how much they need. Then, we'll compare some of the basic approaches used to add real-time to Linux. Stick around, 'cause at the end of the article, we intend to introduce you to a new, evolving "quick reference guide" to real-time Linux products … [Read more...] about Real time Linux
Real time vs real time
Oracle's PR firm just send me a message touting a new study presented by the Evaluator Group that showed that it is easier and quicker to install Oracle VM in an environment supporting Oracle RAC and Oracle Business Suite than installing VMware's vSphere. The main supporting reason was that Oracle's templates for those products drastically reduced the time of installation. As any teenager would say, "Well, duh!" Here's what Oracle's press release has to say Leading Analyst Firm Finds Oracle VM Beats VMware vSphere in Time to Deployment for Key Oracle Applications Users Can Deploy Oracle Real Application Clusters Up to 10 Times Faster with Oracle VM Templates Redwood Shores, Calif. – August 24, 2012 News Facts In a recent report, Evaluator Group found that deploying Oracle Real Application Clusters and the Oracle E-Business Suite using the Oracle VM Templates on Oracle VM was much faster than a traditional install performed with VMware vSphere 5.

MeoCao (unregistered) I agree, I like the GS3 streamlined shape more than 1X, the phone doesn't catch dirt as 1X and it excites me more too b-c it's very different from all other phones while 1X is nice but looks very familiar to older HTC phones.

Racing games tend to emphasize realism over any other factor. Think about it: In a role-playing game, the whole concept is to defy reality and live in a fantasy realm. With shooters, authenticity is not often the goal, since one shot from an AK-47 usually means you can’t just bounce back in the next round. There are some obvious compromises to make sure the game is still enjoyable. But in racing, the main objective is to put you behind the wheel of a $200,000 supercar in a realistic way.At least, that’s where most racing games start – by modeling real cars. That Mercedes-Benz C63 in Forza 4 with the racing tires and the turbo-charged engine better handle like the real thing. When you lumber along in RAM HD 2500 Laramie Longhorn edition in Driver: San Francisco, the fine leather upholstery should look realistic, not like someone just chose a different color in Photoshop.Digital Trends took an exclusive look at four recent racing games and tested the real cars in … [Read more...] about Driving sim showdown: Real cars vs. their in-game counterparts
At this week’s Search Engine Strategies conference in New York, Microsoft began to lay out enhancements planning for its Bing search engine for the first half of 2010…and they include rolling in more real-time information and most effort to understand the intent of a user’s query so the more relevant information is presented immediately.“We have a vision for Bing to serve as a vital assistant to your online decision-making,” said Bing’s general product manager Jeff Henshaw, in a statement. “In these latest designs, you’ll see a lighter, cleaner presentation of results that highlight key actions that will efficiently guide you toward your goal.Part of the enhancement will be an expansion of the Quick Tabs already present in Bing’s “Explore pane”—the Quick Tabs enable users to refine their queries with a single click—and, according to Microsoft, almost half Bing’s users have to make refinements to their … [Read more...] about Bing to Showcase Real-Time Information
Is this a video game, or is it real life? What we know for sure: Watch Dogs 2 is taking great pains to show off the San Francisco Bay Area. The game about hacking the system, due November 15 on Xbox One and PlayStation 4 and November 29 on PC, has re-created "The City by the Bay" all the way down to some very specific details. We took photos of these places with a virtual camera inside the game, then compared them to the real world. The result? Judge for yourself. Note: Best viewed in a desktop web browser.The views from Rincon Park are a pretty good representation of the way Watch Dogs 2 recreates most of San Francisco: just like you remember it, with great attention to detail. Even if in reality, it's a bit bigger, wider and grander. Swapping out Cupid's Span for an old-school optical mouse is a pretty cool touch, and the greenery (and typical passerby!) are pretty spot-on. The skyline looks way different, though, and Rincon … [Read more...] about Watch Dogs 2 vs. real-life San Francisco: spot the difference!
The WebRTC standard aims to make peer-to-peer communication over the Web as easy as picking up a phone. Here's what developers need to know about WebRTC, including how to set it up and what limitations the protocol currently faces.Everyone has had the experience of trying to join a Web conference, only to realize that you must first download some plug-in, upgrade Java or Flash, or install another application. If you've ever had to explain to a customer how or why she need to download and install a plug-in or application to meet with you online, youve probably also had the experience of throwing up your hands and saying, "You know what? I'll just call you."[ALSO: Retro browser battle: IE vs. Netscape]Live audio and video streams and live conferencing over the Web are changing business and personal communications, but theyre often deemed too complicated or unreliable for many end users. Certainly, creating a real-time communications (RTC) application is certainly too complicated for the … [Read more...] about With WebRTC, Real-Time Communications Come to the Browser
On Feb. 16, 2016, Apple refused to comply with a court order to help the FBI unlock an iPhone used by Syed Rizwan Farook, one of the two suspected shooters in the San Bernardino terrorist attack on Dec. 2, 2015. Credit: 1000 Words/Shutterstock The case has been in the headlines ever since, and we've tried to keep up with the daily events surrounding it. The next hearing in the case was set to have been on March 22, but it was abruptly canceled as the FBI said it may have found a way into the phone that doesn't involve Apple. The FBI was given until April 5 to see whether its new method worked, but on March 28 announced that it had, and that it no longer needed Apple's assistance. Here's a quick timeline, in reverse chronological order, of this convoluted case, with the most recent news up top.For deeper examinations, check out our lengthy explanation of the Farook case, and an FAQ explaining the larger controversy over smartphone … [Read more...] about Apple vs FBI Timeline: What You Need to Know
"Machine-generated data," said Splunk VP of Business Analytics Tapan Bhatt in a recent Q&A, "is one of the fastest growing and complex areas of big data. It's also one of the most valuable, containing a definitive record of all user transactions, customer behavior, machine behavior, security threats, fraudulent activity, and more."Machine data is growing exponentially.

Men and women don’t see eye to eye on the benefits of virtual communication. New research has found that men are more likely than women to say that electronic communication improves productivity. Overall, 62 percent of men say electronic communication increased their productivity compared with just half of women. Additionally, 43 percent of say that virtual communication helps to improve workplace relationships, while just 8 percent say it hurts relationships. Researchers also found there were differences among age groups when it comes to seeing the value of electronic communication. Sixty-five percent of respondents between the age of 25 and 34 say virtual communication increases productivity. However, that number shrinks to 52 percent when it comes to respondents ages 35 and older. While workers may be skeptical of virtual forms of communication, those technologies are growing at work. Forty percent of workers say they worked with someone for an … [Read more...] about Virtual vs. Real Life Communication: What Do Workers Prefer?
