If you find yourself gaming in a noisy environment and are trying to keep your contribution to the noise down by using headsets it can be frustrating if you cannot hear the game you are playing.  ASUS has a way to solve that, thanks to the active noise cancellation in their Republic of Gamers Vulcan ANC Pro Gaming Headset.  Red & Blackness Mods tried out a pair for review and were impressed by the light weight of the headset as well as detachable mic for when you don't need to communicate with team mates.  They were not overly impressed with the sound quality but as these are specifically designed for gaming that is not a major concern and not attempting for high end audio helped keep the price down.


"Asus mostly known for their high end laptops and motherboards have recently started pumping out various accessories and even touchpads. Today we are taking a look at the Asus Vulcan ANC Pro Gaming headphones that you can pick up for around 50$. What type of quality and sound quality can we expect from these?"

IDF is coming soon

Subject: General Tech | August 2, 2011 - 03:07 PM |
Tagged: idf, intel developers forum, Ivy Bridge, haswell

At last years Intel Developers Forum, the star of the show was Sandy Bridge as we had not yet seen the chip in action.  That seems longer than a year ago, but it was only last September which means that we are drawing close to the 2011 IDF.  According to DigiTimes this year they will be focusing on mobility products, as we know Intel is working on a new(ish) form factor which they are calling Ultrabook which will replace the CULV form factor that we have known previously.  There were not that many ultrabook branded Sandy Bridge products released this year and with the upcoming release of Ivy Bridge it seems that there won't be many in the future, as Ivy Bridge is intended to do everything Sandy could and use less power doing it.  The other focus that DigiTimes expects to see, as do we at PC Perspective, is more information on Haswell which will be the next generation of Intel chip architecture.  We don't expect to see working silicon until 2013, but you can expect a lot more information about the instruction sets it will use, which is only to be expected at a developers conference.


"CPU maker Intel is set to host its Intel Developer Forum (IDF) show in San Francisco from September 13-15 and its plans for ultrabook, upcoming Ivy Bridge- and Haswell-based processors as well, as its strategy for next-generation tablet PC processor, are all expected to become focuses at the show, according to sources from PC players.

Intel, was originally set to enter the Ivy Bridge-based CPU generation in the fourth quarter of 2011, but after considering the yield rate of the 22nm process and the market status worldwide, the company, in the end, decided to postpone the launch of the new-generation CPU to March of 2012, allowing a smooth transition between the two generation of CPU structures.

In addition to the Ivy Bridge structure, Intel is also set to reveal the detail specifications of its Haswell processor, which will appear in 2013, at IDF in September, the sources noted.

As for ultrabook, Intel will display several completed models from the first-tier notebook players including Asustek Computer, Hewlett-Packard (HP) and Lenovo, at the show with Intel is also expected to provide the detail of its ultrabook design concept as well as its three stages of execution plan for the device.

For tablet PCs, Intel has been cooperating with Google to pair up its Atom Z670 processor with Android 3.0, while will showcase its latest progress in MeeGo and AppUP Center at the show."

Mozilla Hints At New Firefox Design, Closely Resembles Google Chrome

Subject: General Tech | August 2, 2011 - 11:43 AM |
Tagged: firefox, chrome, browser

The Firefox UX development team recently posted a presentation showing off some of the latest design and UI (user interface) improvements for the popular Firefox web browser by Mozilla. While not all of the design choices shown in the presentation will make it into the Aurora or other beta builds, they do indicate that Mozilla is at least considering mixing up their traditional interface for upcoming releases. The image below is one of the screenshots included in the presentation, and at first glance it may be mistaken for Google's Chrome browser. However, upon closer inspection it becomes clear that Mozilla have not simply copied Chrome's minimalist design but they have gone with a similar tab design, continued with the transparency that is already present in certain builds and sprinkled some Mozilla flair on top to create one possible look for a future Firefox browser.


Some other proposed changes of the design include a new menu that is icon based versus word lists and is located on the right side of the window as well as an improved full screen experience that seeks to give web apps the screen real estate they need.  A new home tab and add-on manager interface are also proposed changes.  As shown in the screenshot above, tabs that are not in focus, have their backgrounds become fully transparent so that only the text is visible.  This definitely helps the main tab stand out and may help in reducing the amount of distraction users face when having multiple tabs open.


While these are only proposed changes, it is apparent that Mozilla are planning some kind of major UI overhaul if they can get the users to accept it, and the next major release may well see a slightly more chrome-esque appearance with that special Firefox flair.  What are your thoughts on the proposed designs, do they seem likely?  If you are still using Firefox, what features of other browsers would you like to see Firefox emulate?

Windows XP (Finally) Falls Below 50% of Windows' Market Share

Subject: General Tech | August 2, 2011 - 07:54 AM |
Tagged: windows, operating system, microsoft

Windows XP is almost old enough that revisionist historians can have a crack at it without anyone speaking out against it. That is, it would be if not for the large number of users still using the operating system at their home and work. The decade old operating system has only now fallen below 50% of Windows' market share. More specifically, the slip in market share occurred between June and July where it fell 0.63% to a total of 49.94%.

graph (2).png

The numbers are percentages of MS's total 87.66% market share.

In comparison, Windows Vista holds a much smaller 9.24% market share after dropping 0.28%. Microsoft’s most recent operating system, Windows 7; meanwhile, saw a gain of 0.74% to a total of 27.87% market share, which puts the new operating system well on its way to overtaking the XP juggernaut. Techspot has the full scoop on the market share situation, which you can read about here.

Ivy Bridge and X79, it might not be great news but now you know

Subject: General Tech | August 1, 2011 - 01:53 PM |
Tagged: Ivy Bridge, x79, Waimea Bay, sandy bridge-e

It almost seems as if AMD is the only company managing to keep up to their schedules, though you could argue that they don't have a CEO cracking the whip and pushing forward release dates.  First NVIDIA's GPU woes and now thanks to VR-Zone we know that the X79 Waimea Bay chipset won't be made available until November, which significantly reduces the chances of it being under your Christmas Tree.  It should get them to major manufacturers in time for them to consider the platform when they release their 2012 lineup, but as system builders we can only hope that someone pushes out a product as quickly as possible, so we can pick it up and spend January dealing with the inevitable bugs you get from pushing something out early.


But wait, that's not all ... how does an Ivy Bridge processor locked at a 100MHz base clock strike you?  It seems that is what Intel is planning on releasing with both Ivy Bridge and Sandy Bridge-E, with a less than useful exception.  Both chip architectures will be theoretically overclockable, but not in the single MHz steps that we have become used to.  Instead Ivy Bridge will offer you the ability to jump from 100MHz to 133MHz, no stops in between.  Sandy Bridge-E will offer higher stops but again it will limit you to only those frequency jumps, something the overclocking community is not going to appreciate. 


"We don't like to be the bringers of bad news, but it's come to our attention that Intel has decided to change its high-end consumer Waimea Bay platform one more time before it launches. The only good news is that we've managed to pin-point which month the platform is expected to launch and that is November and there are several reasons behind this choice."

Don’t shoot the megaphone: Battlefield 3 Alpha benchmarks

Subject: General Tech | July 31, 2011 - 01:17 PM |
Tagged: battlefield 3

A non-disclosure agreement is created for those times where certain people need to receive information, get demonstrations, and so forth before the organization wishes to release to the public. We respect the wishes of the individuals and organizations that provide us with information that assists us with our jobs. Currently Battlefield 3 is undergoing private Alpha testing for a select number of invitees – I am not one of those invitees (at least, as of the time of this writing) and thus have no obligation to keep silent on information that was leaked to the public. That is convenient, of course, as some information leaked out on system benchmarks with a wide variety of video cards and processors pitted against DICE’s upcoming shooter.


The first thing to realize, and one of the main reasons for the non-disclosure, is that development builds are development builds: optimizations will be made that will speed things up; enhancements will be made that may make things possibly slower but better for some reason or another. Do not assume that these numbers will even closely reflect the finished product, just the state of the game as it exists right now.

That said and in mind: to expect a smooth experience at 1080p you should anticipate having a GTX 460 or Radeon 5830 as your minimum and a GTX 560 Ti or a Radeon 6950 if you want to hover at around 60 FPS. The GTX 590 actually fell well below the GTX 580 and even fell below the GTX 570 which means that SLi is not yet supported… which should be no surprise for an unreleased game! On the CPU side of things, while no Sandy Bridge processors were tested it looks like performance will hit a bit of a plateau around the 6-core Phenom IIs, upper Core i5, and lower Core i7 parts. Battlefield 3 Alpha really looks as if it appreciates four or more cores thumbing its nose at all the dual core offerings tested. If you would like to see more, check out GameGPU’s page.


Seconds of Raspberry Pi: $25 a slice, $35 with whip cream

I must say, that unlike cake: pie is the foundation of everlasting relationships – like circumference and diameter! That, and cake always seems to end up in lies (yes, that horse is still twitchin’). While my personal favorite flavor is blueberry I might just become fond of Raspberry Pi in the near future. We originally reported on the organization dedicated to providing computing technology to the masses a few months ago when they showed off their prototype computer-in-a-usb-stick. More progress on the logistics as well as a firm specification on the PCB have occurred since then and it aligns nearly perfectly with original predictions.


That… doesn’t really look edible…

(Picture from Raspberry Pi)

The original prediction was a $25 device 700 MHz device backed by 128MB of RAM and an OpenGL ES 2.0 1080p-capable GPU. While that is still true, a second model will be released for $35 with double the RAM and an extra USB port for peripheral connectivity due to the addition of the SMSC LAN9512 two-device USB hub. The alpha board is slightly larger than the final design due to the ports required for debugging purposes and contains an extra couple layers on the PCB that will not be present in the final version. It is still expected to ship within the next 9 months (12 from original post) with the target narrowed slightly to likely sometime in 2011.

Duke Nukem Forever has reached 2007 with upcoming DLC

Subject: General Tech | July 29, 2011 - 01:29 PM |
Tagged: duke nukem

You know that part of Portal 2 where you slowly advance in time throughout Aperture Science’s history? That is kind-of what I feel like whenever I play Duke Nukem Forever or it decides to show up in one way or another. At various points in the game you feel like you are walking around through a confused mess of references to Duke Nukem 3D, Half Life, Halo, Team America, and World of Warcraft. With the latest DLC it looks like you have dug up to the year 2007 as Call of Duty: Modern Warfare and Team Fortress 2 get their turn for parody.



(Image from Gearbox Software)

The DLC, aptly called the “Parody Pack”, will contain four maps each with their own characteristic weapon. The first map is a typical modern urban map called “Call of Duke” where you will be given the option to wield the “N00b T00b” as your custom weapon. “Sandbox” is just like it sounds: you fight in a sandbox with children’s toys – and sticky bombs. “Inferno” appears to be one of those old-fashioned teleporter maps where you physically cannot get from point to point without warping at least once; for newer gamers, think somewhat like a Chiron TL34 from Halo only likely less enclosed -- and with a “DFG” for a weapon, whatever that is. Lastly we get the TF2 parody “2Forts1Bridge” where you can mow down people with a minigun. Three game modes are also included: “Freeze Tag” where you must freeze and shatter your opponents, “Hot Potato” which is like keep-away with a woman, and “Hail to the King” which rounds out any classic shooter with free for all deathmatch. It will be available in the autumn for free if you pre-ordered Duke though there is no word on the price if you are not in the “First Access Club”.

Battle the bane of bulging caps, bring back life to your monitor

Tagged: lcd, solder, capacitor, DIY

Over at The Tech Report you will find a handy guide on restoring a monitor with busted caps to working condition, for not much money nor effort. A bit effort is all that you need to track down a dead capacitor on the circuit board, identified by the bulge which will be apparent at the top of the cap.  Once you've found it you just need to desolder it and swap in a new one and your once broken monitor will be working again.  Even better, this procedure can resurrect any peice of equipment you have which is suffering from failed capacitors.  If you've never used a soldering iron to fix something, this would be a great place to start.


"In his latest blog post, our own David Morgan shows how to bring a monitor back from the dead with a simple capacitor transplant."

Minecraft: Soon with more ways to get messed with!

Subject: General Tech | July 29, 2011 - 02:35 AM |
Tagged: Minecraft

Minecraft, the insanely popular videogame from independent developer Mojang, follows in the PC gaming history of providing customers with constant free content updates along with the usual bug-fix patches. Many developers have been swayed recently by the thought of micro-transactions and have to some extent pushed their customers toward paying for whatever content was not on the disk, and sometimes even paying extra for that too. Notch, the most high-profile member of Mojang, has been teasing about possible additions to be made in upcoming patches: the possibility of boss fights and a screenshot of an enigmatic new mob.


I wonder if the bosses will have derpy eyes too.

One thing that has become a common view about Minecraft is that it will kill you and aggravate you in many annoying ways unless you are very careful (and often when you are). The creeper is often considered annoying by Minecraft players due to its ability to spawn or move into difficult to deal with spots, be even more difficult to deal with when there, and cause demolish your creations when there. Many players got frustrated enough to the point of disabling the mob or its destructive capabilities altogether. A development screenshot posted by Notch on his Google+ a new experimental mob doing what many fear could be the new creeper: hold a block! Where did (s)he get the block? What will (s)he do with it? Could the game itself grief you? No other details are available yet but it certainly puts players off ease for the possibilities… but not necessarily in a bad way.


See this? This is someone’s nightmare.

(Image from Notch, Mojang)

Mojang has wanted to lead Minecraft more towards a more typical game model as an alternative to a tool for creation without much else to do thereafter. Due to an admiration of another Minecraft-like game, Terraria, Notch has mentioned the desire to add boss battles to the game. The catch is that, like Terraria, you would have the ability to create the terms for the boss battle rather than be guided to a game designer’s creation until you either quit playing or overcome it and move past it. I should also say that there have been plenty of additions to Minecraft that have been planned or worked on in the past that ultimately get scrapped so there is no guarantee that anything in this news story will end up in the game proper.

Ya Rly. Intel releasing new CPUs for servers

Subject: General Tech, Processors | July 28, 2011 - 06:50 PM |
Tagged: Sandy Bridge-EP, Intel

Since we got back together with Sandy B we have played a few games, made a couple home movies together, and went around travelling. Now that our extended vacation is over Sandy decided it is time to get a job. Sandy B was working part-time as a server and apparently like her job because Intel brought her to a job opening in Jaketown. Intel has apparently released details on their server product, Sandy Bridge-EP “Jaketown” that will debut in Q4, to replace the current server line of up-clocked desktop parts with disabled GPUs.


NO WAI!!!!!

According to Real World Tech, Intel’s server component will contain up to 8 cores and sport PCI-Express 3.0 and Quick Path Interconnect 1.1. Rumors state that the highest-clocked component will run at up to 3GHz with the lowest estimated to be 2.66GHz. The main components of the CPU will be tied together with a ring bus, although unlike the original Sandy Bridge architecture the Sandy Bridge-EP ring will be bi-directional. Clock rates of the internal ring are not known but the bidirectional nature should decrease travelling distance of data by half on average. The L3 cache size is not known but is designed to be fast and low latency.

Intel looks to be really focusing this SKU down to be very efficient for the kinds of processes that servers require. There is no mention of the Sandy Bridge-EP containing a GPU, for instance, which should leave more options for highly effective x86 performance; at some point the GPU will become more relevant in the server market but Intel does not seem to think that today is that day. Check out the analysis at Real World Tech for more in-depth information.

SanDisk joins the hard drive haters with the release of their Ultra SSDs

Tagged: ssd, sandisk, sandisk ultra

SanDisk is releasing a line of SSDs, called the Ultra series.  They are not aimed at the high end market, they use the older SATA 2 interface and claim sequential transfer speeds of 280MB/s read and 270MB/s write.  The prices should range from $130 for the 60GB product to $450 for the 240GB model, which puts them about middle of the road for pricing.  They also list expected lifetime in terms of the amount of data written to them; 40TB of data written for the 60GB up to 120TB of total data written to the 240GB.  The Register covered the release here.


"SanDisk has a new Ultra line, a cruise flash missile aimed at taking out PC and notebook hard drives and replacing them with much faster SanDisk SSDs.

These are 2.5-inch format, 2-bit multi-level cell flash drives, coming in 60, 120 and 240GB capacity points. The Ultra brand is used by SanDisk for consumer flash products such as SDHC cards, and now a trio of SSDs will be sold under the Ultra name."

Sony: Lighthearted and Colorful Ads for Tablets

Tagged: sony, S2, S1

So part one and part two of Sony’s “Two Will” campaign went off to advertise the upcoming launch of the S1 and S2 Honeycomb tablets over the last couple months with promise of three more on the way. Recently Sony made good on that promise and posted the third last “Two Will” video to Youtube and this one was substantially different from the ones before it. Titled “Filled with fun”, this one has much less of a dark and bleak atmosphere trading the harsh shadowing with light and color.

I don't think it's legal to romance a tablet; well, maybe in Japan.

While rails still play an important role, there is much less emphasis on impressing you with perfectly timed plungers pressing the touchscreen as it zips past. Instead, “Filled with fun” passed by various stations which symbolize the various roles of the tablet: music, movie consumption, literature consumption, and games. There is also a strong emphasis on portability and love in the themes of each of their videos.

Why do you think Sony keeps referencing love in these videos? What is the significance of the couch just before the domino “to be continued”? (Registration not required to comment.)

And while Jeremy has fond memories of Wing Commander I just cannot help but see his Kilrathi raise him a Privateer.

The news out of Montreal is good, Deus Ex: Human Revolution is off to the production lines as the gold DVD has been stamped.  That means that come August 23 you will be able to pick it up at stores or use the copy you pre-ordered through Steam.  That doesn't give us any guarantees as to the quality of the game, though the trailers seem good and more importantly the gameplay previews do as well.  With Eidos it is hard to say how good the dialog and story will be as they've been the makers of some of the worst and some of the best examples over the years.  Rock, Paper, SHOTGUN better not have been lied to!


"Humans! The promised day has arrived. Some said it wasn’t possible. Some said rude, badly-spelled things in capital letters. Others were simply impatient. No matter: it has happened. Deus Ex: Human Revolution, the third game in the series that has an awful lot to do with why an awful lot of us remain faithful, unswervingly loyal PC gamers to do this day, has gone gold. And I’m not just talking about its colour pallete. It is finished, Eidos Montreal have just revealed. Complete. Ready. Well, ready as it’ll ever be – and that means its release date on August 23 is actually happening."

Once you had to go digging through old keyboard graveyards to get your hands on a mechanical keyboard, or track down the rare and elusive Das Keyboard.  Now many different peripheral companies offer mechanical keyboards, for instance Razer's new BlackWidow and BlackWidow Ultimate.  This new breed of keyboards are not the familiar buckling-spring switches, instead they a combination of springs and metal clips to provide tactile feedback, the click being an optional feature.  These two keyboards not only give you enough travel and resistance to provide tactile feedback for your fingers, they also included the click so that your ears don't feel left out of your typing experience.  The difference in these two models lies in the Ultimate's programmable macro buttons which the basic model lacks.  Read on to see if the Tech Report had heard enough by the end of the review, or would never go without the click again.

Older than DOS ... but not dirt

Back in the ancient days before the comment "Drop to command prompt" made sense as the command prompt a little known company called Microsoft bought QDOS and renamed it as MS DOS.  That was also back when IBM was the be all and end all of 8086 (and 8080) processors and planned for their newly designed Personal Computer to run an OS called CP/M-86 but couldn't get a good enough deal on the licensing; which lead to Microsoft's product being adopted.  It also lead to the Personal Computer catching on much more quickly and thoroughly than anyone predicted.

From that humble beginning came what was first used to slow your 386DX based computer enough to be able to control Wing Commander and now controls almost 90% of the PCs currently running and keeps techs employed world wide.. 


"Thirty years ago, on July 27 1981, Microsoft bought the rights for QDOS (Quick and Dirty Operating System) from Seattle Computer Products (SCP) for $25,000. QDOS, otherwise known as 86-DOS, was designed by SCP to run on the Intel 8086 processor, and was originally thrown together in just two months for a 0.1 release in 1980."

'Anonymous' Raids: List of 1000 IPs

Subject: General Tech | July 26, 2011 - 10:00 PM |
Tagged: paypal, Anonymous

Recently there was a lot of news about alleged members of Anonymous getting arrested by the FBI across America. 40 search warrants were served against people accused of attacking Paypal from a list, provided by the company, of one-thousand IP addresses carrying the most traffic during the time period of Anonymous’ “Operation Payback”. Wired also has the affidavit from the July 19th search of a couple from Arlington, Texas and their son which includes the ability to seize electronic devices either allegedly used in the attack or contains evidence of the attack.


The importance of living up to your name.

While these searches did not necessarily lead to arrests and were with warrant the concept of linking an IP address with a person is often hotly debated. The “LOIC” tool, a program designed to direct a large amount of traffic at a computer often with the intent of diluting system resources from what the computer is supposed to do, gets its name from the Command and Conquer super weapon, the Low Orbit Ion Cannon. In many cases, traffic from LOIC is easily identifiable as it contains vanity strings as its attack payload and often comes from the user’s personal IP address (not very anonymous); that said, there is nothing to say that the same effects could not be caused by one person controlling an army of a thousand or more virus-infected computers. While I am not commenting on the situations themselves, I do hope that the FBI had more evidence for their 40 warrants than just a random selection of addresses on that list.

Developer Watch: CUVI 0.5 released

Subject: Editorial, General Tech, Graphics Cards | July 26, 2011 - 08:39 PM |
Tagged: gpgpu, Developer Watch, CUVI

Code that can be easily parallelized into many threads have been streaming over to the GPU with many applications and helper libraries taking advantage of CUDA and OpenCL primarily. Thus for developers who wish to utilize the GPU more but are unsure where to start there are more and more options for libraries of functions to call and at least partially embrace their video cards. OpenCV is a library of functions for image manipulation and, while GPU support is ongoing through CUDA, primarily runs on the CPU. CUVIlib, which has just launched their 0.5 release, is a competitor to OpenCV with a strong focus on GPU utilization, performance, and ease of implementation. While OpenCV is licensed as BSD which is about as permissive a license as can be offered, CUVI is not and is based on a proprietary EULA.

Despite the proprietary and non-free for commercial use nature of CUVI they advertise large speedups for certain algorithms. For their Kanade-Lucas-Tomasi Feature Tracker algorithm when compared with OpenCV’s implementation they report a three-fold increase in performance with just a GeForce 9800GT installed and 8-13x faster when using a high end computing card such as the Tesla C2050. Their feature page includes footage of two 720p high definition videos undergoing the KLT algorithm with the OpenCV CPU method chugging at 2.5 fps contrasted with CUVI’s GPU-accelerated 33fps. Whether you would prefer to side with OpenCV’s GPU advancements or pay CUVIlib to augment what OpenCV is not good enough for your needs at is up to you, but either future will likely involve the GPU.
