Duke Nukem Forever has reached 2007 with upcoming DLC

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.

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

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.

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.

Minecraft2.png

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.

minecraft-newmob.png

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.

11-intel.png

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.

Elreg_sandisk_ultra_ssd.jpg

"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

Subject: General Tech, Mobile | July 28, 2011 - 02:12 AM |
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.)

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

Tagged: qdos, msdos, microsoft

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.

The little plus signs are the computer tracking motion. CUVI (top; 33fps), OpenCV (bottom; 2.5fps)

(Video from CUVIlib)

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.

There are speakers and then there are studio monitors, with the difference being quality.  For most gamers and movie watchers there is no point in picking up a pair of studio quality monitors, not only because of the lack of a discerning ear but also because the audio source is unable to provide the quality these monitors need to perform.  Much as Scotches or wines taste similar to the untrained palate, studio quality speakers are for professionals with professional level needs.  If you are one, or simply want the best possible sound reproduction and are willing to spend $300+ for a pair of monitors then you should check out the M-Audio Studiophile CX5 Active Studio Reference Monitor review at ModSynergy.  With a proper audio card and file as a source these monitors will equal a $1000 pair of monitors and are a great deal for those with the ears to enjoy them.

OCZ is never satisfied with the performance of their SSDs in general and their controllers specifically.  After purchasing Indilinx to ensure that their controllers would be of high quality and designed to OCZ's specific needs, they've now been pushing Indilinx to improve on their controllers.  That has lead to Everest, which has a dual core ARM processor and 400MHz DDR3 cache that can support up to 512MB.  The controller is optimized for 8K writes which is perfect for the current flash utilized in SSDs.  OCZ has also optimized the flash memory, developing Triple Level Cell (TLC) which has three layers as opposed to MLC which sports two.  The controller will be backwards compatible, which is a good idea if OCZ wants to license the controller to other manufacturers, which makes sense as Everest should hit 200MT/s as compared to SandForce's current 166MT/s.  There is more that this controller can do, click on over to The Register to read about it.

"OCZ is sampling a new flash controller that gives a picture of future solid state drives.

The company bought Indilinx for its solid state drive (SSD) controller technology in March this year and has now unveiled the Indilinx Everest controller platform.

It has a 6Gbit/s SATA III interface, a dual-core ARM processor and a number of enticing features, such as 3-bit multi-level cell (MLC) support. This is going to be called TLC, for triple-level cell, to distinguish it from today's MLC, which is 2-bit MLC."

Apple is da bomb! Vulnerability found in battery circuitry

Subject: Editorial, General Tech | July 25, 2011 - 10:24 PM |
Tagged: Malware, apple

Okay, so the title is more joke than anything else but security researcher Charlie “Safari Charlie” Miller discovered a vulnerability in Apple devices, sort of. This exploit, which appears to not actually be a security flaw and rather just an over-permissive design, allows an attacker to gain access to your battery control using one of two static company-wide passwords. Charlie has discovered many exploits in the past several years on the OSX and iOS platforms. One of the most high profile attacks he discovered involved a data-execution vulnerability in the iPhone’s SMS handling: under certain conditions your iPhone could potentially confuse inbound text messages as code and run it with high permissions.

Malware assaults and battery charges.

(Image from Apple, modified)

So what does having the ability to write to a laptop’s battery firmware mean? Firstly, remember the old advice of “Get a virus? Reinstall your OS!”? Well assuming you actually can perform a clean install without ridiculous hacking (thanks Lion) the battery controller can simply re-infect you if the attacker knows an exploit for your version of OSX. But how does the attacker know your current version of OSX? Well if you are installing from an optical disk they just need to know a Snow Leopard RTM exploit; unless of course you extract Lion from the Mac App Store and clean install using it – assuming the attacker does not know an exploit for Lion or simply just infects the reinstall media if you created it from the infected computer. True, malware is about money so it is highly unlikely that an attacker would go for that narrow of a market of Mac users (already a narrow-enough market to begin with) but the security risk is there if for some reason you are a tempting enough target to spear-phish. Your only truely secure option is removing the battery while performing the OHHHHHHHH.

You know, while working (very temporarily) on the Queen's University Solar Vehicle project I was told that Lithium cells smell like sweet apples when they rupture. I have never experienced it but if true I find it delightfully ironic.

While that would all require knowledge of other exploits in your operating system, there is a more direct problem. If for some reason someone would like to cause damage against your Apple devices they could use this flaw to simply break your batteries. Charlie has bricked nine batteries in his testing but has not even attempted to see whether it would be possible to over-charge a battery into exploding. While it is possible to force the battery controller to create the proper conditions for an explosion there are other, physical, safe guards in place. Then again, batteries have exploded in the past often making highly entertaining Youtube videos and highly unentertaining FOX news clips.

Overclocking Llano just makes sense, but the RAM not so much

Most reviewers made a financial decision when pairing RAM to review AMD's new Llano A8-3850 processor.  Most chose 1333MHz DDR3, since when building a low cost PC most users are going to choose the lower cost as opposed to spending half the budget simply on DDR3.  After seeing significant overclocks produced by a variety of testers, The Tech Report thought it would be interesting to see the impact of high speed RAM on the performance of an A8-3850, especially the graphics portion.   As it turns out, the decision to go with lower cost RAM made a lot of sense as the the graphical performance did not benefit from faster RAM.

Tagged: msi, Android

Are you a hardcore PC user who likes to tweak your computer? Naturally there is an app for you. MSI has launched an application for the Android Marketplace this morning to allow users wishing to monitor and overclock their computers the ability to use their Android-powered smartphone or tablet for that purpose through their wireless network. This version allows you to monitor temperature, voltage, fan speed and adjust clock rates, voltages, and fan speeds.

afterburner.jpg

Let's hope Angry Birds doesn't see this: Some systems' power consumptions are pigs!

MSI Afterburner APP has relatively modest requirements: a tablet or smartphone device running Android 1.6 or higher, a system running Windows XP or later with a discrete graphics card, access to a network with wireless access for the Android device to link into, and Afterburner 2.1.0 or later installed on the PC. Setting up your PC is relatively simple once you have Afterburner installed as you just need to run, not even install, an application “Remote Server” that you can download from the MSI website linked to from the Android Marketplace link. While this application is too new to be rated, it is free and thus there is little reason to not simply try it out yourself.

With all the research that Ken did, it turns out that Bitcoin mining will not make you rich overnight and possibly cost you more money to create a bitcoin than you will ever see out of it.  Now, according to a study linked to at Slashdot it seems that one of the big attractions of Bitcoins is not true.  Researchers have found that with enough work and data, Bitcoin purchases are not anonymous.  Anonymity was never a major goal for those who first envisioned Bitcoins but it has been touted as a major feature by those who have been mining and spending coins.  If that is why you are interested in the process of mining maybe it is a better idea to switch to an @home project.

"Researchers from University College Dublin have conducted an analysis of anonymity on Bitcoin, and found it is not inherently anonymous, and that in many cases, users and their transactions can be identified. They use techniques such as context discovery and flow analysis to investigate and visualize an alleged theft of Bitcoins, which, at the time of the theft, had a market value of approximately half a million U.S. dollars."

Intel MLAA: Matrox had the right idea, wrong everything else

Subject: Editorial, General Tech, Graphics Cards, Processors | July 22, 2011 - 08:20 PM |
Tagged: MLAA, Matrox, Intel

Antialiasing is a difficult task for a computer to accomplish in terms of performance and many efforts have been made over the years to minimize the impact while still keeping as much of the visual appeal as possible. The problem with aliasing is that while pixels are the smallest unit of display on a computer monitor, it is large enough for our eye to see it as a distinct unit. You may however have two objects of two different colors partially occupy the same pixel, who wins? In real life, our eye would see the light from both objects hit the same retina nerve (that is not really how it biologically works but close enough) and it would see some blend between the two colors. Intel has released a whitepaper for their attempt at this problem and it resembles a method that Matrox used almost a decade ago.

Looking at the problem of antialiasing, you wish to have multiple bits of information dictate the color of a pixel in the event that two objects of different colors both partially occupy the same pixel. The simplest method of doing that is dividing the pixel up into smaller pixels and then crushing them together to an average which is called Super Sampling. This means you are rendering an image 2x, 4x, or even 16x the resolution you are running at. More methods were discovered including just flagging the edges for antialiasing since that is where aliasing occurs. In the early 2000s, Matrox looked at the problem from an entirely different angle: since the edge is what really matters, we can find the shape of the various edges and see how much area of a pixel gets divided up between each object giving an effect they say is equivalent to 16x MSAA for very little cost. The problem with Matrox’s method: it failed with many cases of shadowing and pixelshaders… and came out in the DirectX 9 era. Suffices to say it did not save Matrox as an elite gaming GPU company.

Look familiar?

Intel’s method of antialiasing again looks at the geometry of the image but instead breaks the edges into L shapes to determine the area they enclose. To keep the performance up they do pipelining between the CPU and GPU which keeps the CPU and GPU constantly filled with the target or neighboring frames. In other words, as the GPU lets the CPU perform MLAA, the GPU is busy preparing and drawing the next frame. Of course when I see technology like this I think two things: will this work on architectures with discrete GPUs and will this introduce extra latency between the rendering code and the gameplay code? I would expect that it must as the frame is not even finished let alone drawn to monitor before you fetch the next set of states to be rendered. The question still exists if that effect will be drowned in the rest of the latencies experienced between synchronizing.

AMD and NVIDIA both have their variants of MLAA, the latter of which being called FXAA by NVIDIA's marketing team. Unlike AMD's method, NVIDIA's method must be programmed into the game engine by the development team requiring a little bit of extra work on the developer's part. That said, FXAA found its way into Duke Nukem Forever as well as the upcoming Battlefield 3 among other games so support is there and older games should be easy enough to just compute properly.

The flat line is how much time spent on MLAA itself, just a few milliseconds and constant.

Performance-wise the Intel solution performs ridiculously faster than MSAA, is pretty much scene-independent, and should produce results near the 16x mark due to the precision possible with calculating areas. Speculation about latency between render and game loops aside the implementation looks quite sound and allows users with on-processor graphics to not need to waste precious cycles (especially on GPUs that you would see on-processor) with antialiasing and instead use it more on raising other settings including resolution itself while still avoiding jaggies. Conversely, both AMD and NVIDIA's method run on the GPU which should make a little more sense for them as a discrete GPU should not require as much help as a GPU packed into a CPU.

Could Matrox’s last gasp from the gaming market be Intel’s battle cry?
