remote gaming – OnLive Cloud Gaming Service to Launch in June 2010

OnLive Cloud Gaming Service to Launch in June

Matt Peckham

OnLive

For the price of a low-end PC plus a monthly fee you’ll soon be able to play ultra-high-end games like Borderlands, Mass Effect 2, Assassin’s Creed 2, and Crysis. According to VentureBeat, the service, dubbed OnLive, will launch in June after eight years of research and development, offer up to 720p-caliber high-def gameplay, and cost $14.95 a month.

Billed as a games-on-demand service, OnLive handles all the intensive game processing on the server side, so your local computer doesn’t have to. What you see is tantamount to a “screen-scrape” video feed send to your client device. All the intensive computing that might normally convert the insides of your homebrew rig into a mini-bake oven renders instead in the cloud.

It’s an ancient concept in computing terms–the model’s existed since mainframes and green-screens, in fact–but until recently, no one’s come up with a system to transfer high-bandwidth video with low enough latency to pass muster with gamers.

remote port forwarding

Posted by John on 8th March 2010

This is an interesting VPN concept, perhaps to allow you to run a home https web server, but to make your content available to users stuck behind the Great Firewall, etc.

Though from long work in the security arena, keep in mind that “no solution is 100%” . . .

PuSHPress for wordpress.org

Posted by John on 4th March 2010


PuSHPress: A PubSubHubbub Plugin For WordPress

Posted in 3 Mar 2010  9:49 am Joseph Scott

PubSubHubbub, or PuSH, is now supported on all WordPress.com blogs. For those running sites using the WordPress.org software the PuSHPress plugin is available to do the same thing. The big difference in this plugin compared to the other PuSH WordPress plugins is that it includes a PuSH hub built in.

A little bit of PubSubHubbub background

Like rssCloud, PuSH adds a line to your feed to let clients know where they can send PuSH subscription requests. In the RSS2 feed this looks like . . .

some new intel 32nm chips to support hardware AES acceleration

Posted by John on 3rd February 2010

(this next bit can affect everything from certain web transactions, to VoIP, to full disk encryption . . .)

AES-NI Performance Analyzed; Limited To 32nm Core i5 CPUs

2:00 AM – 02/02/2010 by Patrick Schmid and Achim Roos

Security is an important topic these days. However, it’s typically only recognized as important by professionals. If security were to suddenly turn into a mainstream selling point, though, then perhaps it’d make more sense for companies like Intel to promote it.

The Advanced Encryption Standard (AES) has already been adopted by the United States government—including the NSA—along with many other institutions. Intel’s 32nm Clarkdale-based CPUs (only the Core i5-600-series, so far) now promise significant performance benefits for AES encryption and decryption via new instructions. Today we’re looking at the real-world benefits of Intel’s AES-NI functionality, comparing a dual-core Core i5-661 with AES New Instructions (AES-NI) to a quad-core Core i7-870, which lacks the new encryption acceleration capability.

Encryption is used much more intensively than you might suspect. Consider Internet sites that hold you sensitive personal information, or utilize sensitive data for transactions. They all use protocols like Transport Layer Security (TLS) or Secure Sockets Layer (SSL). VoIP, instant messaging, and email may also be protected with these protocols. Virtual Private Networks (VPNs) and electronic payments are other popular encryption applications.

However, TLS and SSL are cryptographic protocols for secure communication, while AES is a general-purpose encryption standard. It can be used to encrypt individual files, data containers, archive files, entire drives (including thumb drives), and even multi-drive volumes. AES can be implemented in software, and there are products based on hardware acceleration as well, since encryption/decryption represent a rather significant workload. Solutions like TrueCrypt or Microsoft’s BitLocker, which is part of Windows Vista and Windows 7 Ultimate, are capable of encrypting entire partitions on the fly.

How to run your own SFTP server under Windows

Posted by John on 2nd February 2010

Credit : Nicholas Fong,  who also has many other helpful articles at his site.

For the latest version of his accumulated guide / information, please see the authentic SFTP server under Cygwin article at http://pigtail.net/LRP/printsrv/cygwin-sshd.html ) ;)

It worked fine for me in Windows 7 on the first shot.  While I’d already been using Cygwin, the instructions were clear, though I did follow the Vista section at step 5.  The version I used was dated November 18, 2009.

Good luck!

Javascript for advanced functions

Posted by John on 30th January 2010

Pretty nifty use in javascript : http://point-at-infinity.org/jsaes/

Also nice : http://point-at-infinity.org/ssss/ and http://point-at-infinity.org/seccure/ (also both crypto related . . .)

Edgan Allen Poe - cryptoN.B.  I was sorely tempted to post an image relating to the futility of trying to contain crypto / ideas that was penned on flesh, in an image titled “howto-export-crypto-system-from-usa.jpg” (!)

But I resisted, as I try to keep this site friendly even to the most prudish families, etc.

SSD upgrade for the desk

Posted by John on 29th January 2010


Upgrade a Desktop Machine to SSD : The Future Arrives

By William Van Winkle , published on January 22, 2010 at 3:10 PM

I relish making changes to my primary work PC only slightly more than dental surgery. Things can go wrong. My productivity vanishes. I’ll deal with work-arounds for months before cracking open my case for an upgrade.

And yet, I just published a story called “Can Bargain SSDs Give Windows A Quantum Performance Leap?” for Tom’s Hardware, and what I’d found when doing that story blew my mind. I was used to measuring Windows startup times in minutes, literally being able to make lunch in the time it took to go from power off to having all of my normal apps loaded. I built a similar configuration on my bench, placed it on Western Digital’s VelociRaptor (the fastest SATA hard drive around), and got a full load time of 65 seconds. Then I cloned the configuration to Kingston’s entry-level SSDNow V-Series SSD and saw the load time plummet to only 27 seconds. Feeling like Will Smith at the controls of some fresh alien tech, I hollered, “Oh, I have got to get my Windows 7 one of these!”

We heard a lot of off-the-record praise from readers after publishing our recent feature on laptop SSD upgrading. Experienced users tend to populate our forums, but those who have never done a hands-on system upgrade tend to hang out invisibly in the background and it seems they appreciated a step-by-step guide to the upgrading process. It’s primarily for this latter group that we’re returning now with a companion piece on how to take your desktop PC through the same process…only I’ve added a new twist, as you’ll see below . . .
