Running an EXT4 RAID on the Linux 4.0 kernel? Better spray for bugs!

Subject: General Tech | May 21, 2015 - 12:40 PM |
Tagged: linux, EXT4, raid, bug

On Tuesday a bug was discovered to have been introduced to Linux 4.0 kernel when a fix was added to deal with RAIDs where the chunksize not a power of 2, a problem present since Linux 3.14-rc1.  This fix has been causing corruption on RAIDs and the file system on that RAID, making many an unhappy Arch Linux user.  Only users of rolling release flavours will be effected, distros with scheduled updates like RHEL or Ubuntu are not effected at this time.  The good news is that as of today there is a fix available if you wish to apply it, as well as defining the fix which caused the issue.  Check out both at Phoronix.

"A few days ago we reported on an EXT4 file-system corruption issue being discovered within the stable Linux 4.0 kernel series. The good news is the issue has been uncovered and a patch is available, but it could still be a few days before it starts getting sent out in stable updates."

The new and not quite as pretty as advertised Witcher is here from CD Projekt RED, available from GoG among other places. Rock, Paper, SHOTGUN have started another one of their ongoing diaries to share their experiences, so far involving a bare bum and the amazing Tutorial Man.  They also went straight for the dream sequence right off the bat; a smart move to get that over and done with in the early stages.  There will be more, as this is a very large game.   If you are looking for more details on graphics settings than to turn off Vidal Sasson, there is a post here discussing the options they used as well as the links below.

GoogleU just got noiser; tweets are returning to your search results

Subject: General Tech | May 20, 2015 - 01:02 PM |
Tagged: twitter, google

Several years back Google thought it would be fun to include Tweets in Google searches and while they were smart to discontinue that, the reasoning behind ending it, Google+, may not have been as sound.  According to Slashdot, once again your searches for information on Google will be accompanied by 140 character posts of scintillating wisdom which will obviously impart far more knowledge than the citation you were looking for.  This should also do wonders for those looking to limit the perspectives and opinions they are exposed to as dissenting views can easily be drowned out by tweets that reinforce your beliefs just by minor alterations the text in your search. 

On the plus side, one comment on Slashdot shows how to add operators back into your searches, just paste &tbs=li:1 at the end of the URL once you have searched.

Add "&tbs=li:1" to your keyword search string. For example: https://www.google.com/search?q=%s&tbs=li:1

"Google will now begin showing tweets alongside search results. Mobile users searching via the Android/iOS apps or through the browser will start seeing the tweets immediately, while the desktop version is "coming shortly." The tweets will only be available for the searches in English to start, but Twitter says they'll be adding more languages soon."

Raptr's Top PC Games of April 2015

Subject: General Tech | May 15, 2015 - 11:56 PM |
Tagged: raptr, pc gaming

The PC gaming utility, Raptr, is normally used to optimize in-game settings, chat and socialize, and record game footage. It also keeps track of game-hours and aggregates them into a list once per month, which makes it one of the few sources for this type of data on the PC. We were late on it last month, which means that another was posted just a week later.

caas-most_played_april-2015.jpg

April marks the release of Grand Theft Auto V for the PC. It went live on the 14th and, despite only counting for half of the month, ended up at 4th place. Next month's survey will tell us whether the post-release drop-off was countered by counting Grand Theft Auto for a full month, which is double what they have now. It was just 0.17% of global play time behind CS:GO. Despite an error on the graph, it knocked DOTA 2 down to fifth, and Diablo III down to sixth. In fact, just about everything below Grand Theft Auto V dropped at least one rank.

Only three games actually gained places this month: ArcheAge, Warframe, and Spider Solitaire. Yes, that game is now the 19th most played, as tracked by Raptr. You could sort-of say that Hearthstone gained a rank by not losing one, but you would be wrong. Why would you say that?

League of Legends dropped less than a percent of total play time, settling in at about 21%. This is just about on target for the game, which proves that not even Rockstar can keep people from having a Riot.

Budget headphones that are just good enough, Ozone Rage ST

Tagged: audio, ozone, Rage ST, gaming headset

With a pricetag of $40 many may be a bit leery of purchasing the Ozone Rage ST Headset as it is significantly lower in price than most gaming headsets which implies lower quality too.  It does use the 40mm drivers common in most headsets with a response range of  20-20kHz but the microphone is omnidirectional as opposed to unidirectional which means you will send background noise.  Modders-Inc tried it out and were pleasantly surprised; while it has none of the extra features that $100+ headsets do, the overall quality was worth the price of admission.  If you are in need of a headset but are strapped for cash, these are a good choice for you.

"Despite the stereotype, gamers are social creatures too. Competitive games after all requires another person to play with, but as expressive as some gestures may be such as virtual teabagging, it is not nearly as effective in conveying what you really feel when you shout out expletives through a headset. It feels very natural in fact that one almost feels …"

Another juicy rumour; Lenovo wants MSI's gaming laptops?

Tagged: rumours, msi, Lenovo

When you think of Lenovo laptops you tend to think of suits and office suites, not Cheetos and Red Bull but DigiTimes has heard tell that this could possibly change.  With Acer, Asustek's ROG and Dell's Alienware lineups all seeing decent profits from the niche market of high end gaming laptops the rumour is that Lenovo would like in on some of that filthy lucre.  DigiTimes' source posits that MSI's gaming laptop subdivision would be the obvious target for Lenovo.  It is possible that this is all hot air but Lenovo is a huge company and could easily afford to buy a division of a competitor, if they were willing to sell.

You may have had the pleasure of using the Google Goggles image identification app, not so much for its successes as for its often hilarious misses.  There is now a new image identification app from Wolfram Alpha which you can try out.  The Register immediately tried a random picture of Stephen Wolfram who is apparently a podium in disguise but Image Identify seems very fond of capyberas.   Head on over to amuse yourself and of course only use your pictures for proper training as we wouldn't want to reclassify the podium as Daddy, now would we?

Firefox 38 Launches with (and also without) DRM Support

Subject: General Tech | May 13, 2015 - 05:06 PM |
Tagged: mozilla, firefox, DRM

Mozilla has just released Firefox 38. With it comes the controversial Adobe Primetime DRM implementation through the W3C's Encrypted Media Extensions (EME). Or, maybe not. If you upgrade the browser through one of the default channels, the Adobe Primetime Content Decryption Module will appear in the Plugins tab of your Add-ons manager on Windows Vista or later (but it might take a few minutes after the upgrade).

Mozilla_Firefox_logo_2013.png

Alternatively, you can use Mozilla's EME-free installer for Firefox and avoid it altogether.

I have mentioned my concerns about DRM in the past. EME does not particularly bother me, because it is just a plugin architecture, but the fundamental concept does. Simply put, copy protection does very little good and a whole lot of bad. If your movie is leaked before it is legally available in consumer's hands, as it regularly does, then what do you expect to accomplish after the fact? It takes one instance to be copied infinitely, and that often comes from the film company's own supply chain, not their customers. Moreover, it is found to reduce sales and hurt customer experience (above and beyond the valid ideological concerns).

Beyond the DRM inclusion, several new features were added. One of the more interesting ones is BroadcastChannel API. This standard allows a web application to share data between “contexts” that have the same “user agent and origin”. In other words, it must be on the same browser and using the same app (even secondary instances of it). This will allow sites to do multi-monitor split screen, which is useful for games and utilities.

WebRTC has also been upgraded with multistream and renegotiation. Even though the general public thinks of WebRTC as a webcam and voice chat standard, it actually allows arbitrary data channels. For example, “BananaBread” is a first person shooter that used WebRTC to synchronize multiplayer state. Character and projectile position is very much not webcam or audio data, but WebRTC doesn't care.

Firefox 38 launched on May 12th with an optional, DRM-incompatible build.

The Tech Report pulled out their wheel and pedals, tied their chair to their desk and tried out Project Cars, a game which shows off just what a good PC is capable of.  The cars, tracks and weather are all rendered in amazing quality with lifelike reflections and lighting.  Even better is the feel of the game, realistic handling work with the graphics to immerse you fully into the game. Their are options to help the novice driver get their skills up to speed and while there may not be quite as many tracks and cars to choose from as games such as Forza, the realism more than makes up for it.  It will also work with a controller and Steam Big Picture for those who prefer to drive from the couch.

Epson's new 3D glasses

Epson has teamed up with NGRAIN to create the Moverio BT-200 smart glasses for use in industrial design and repair.  The glasses are connected to a controller to minimize the weight of the actual glasses as well as allowing you control options on the 3D view you see through the glasses.  The Register were not overly impressed with the image nor the interface but could certainly see the usefulness in the demonstrations that were conducted.  One benefit the glasses do offer is dual usage, they can be used both to show 3D images as well as augmented reality overlays when looking at physical objects, allowing to use the interface you prefer.

Use your SHIELD to stream games over NVIDIA GRID at 1080p

Ryan and the crew have tested out NVIDIA's GRID, the cloud streaming service that lets you play games at 720p, as long as you have a 10 Mbps down connection on a network with a NVIDIA GameStream-ready 5 GHz Wi-Fi router and 60 ms or less ping time to a GRID server.  In testing Ryan did notice lag but he still found them playable once he mentally adjusted to the delay.

tabletpic.jpg

Today NIVIDA announced an upgrade to the GRID service, 35 of the 50 games on the service can now stream at a full 1080p and 60fps including Batman: Arkham Origins, Devil May Cry 4 and Dirt 3 Complete Edition.  In order to properly enjoy the HD quality you will need a compatible router from the list linked to above and connection of at least a 30 Mbps down, with 50Mbps being recommended by NVIDIA for best results.

Remote door answering with the Ring

Ryan was impressed with Google's Nest Learning Digital Thermometre and recommended it a few years back as a great holiday gift, which is still true to this day.  A company called Ring is making inroads into the smart home market with their self titled second generation product.  Their original product was Doorbot, which some hated and many liked but which is nowhere near as interesting as the new Ring.  It is a 720p camera, with a motion sensor, microphone and speaker all powered by the small current provided by your existing doorbell circuits and a battery backup good for about a year.  It connects to your house and the Cloud via WiFi and is capable of not only ringing on your iOS7+ or Android 4.0+ phone but also to send the video so you can interact with whoever is at your front door even when you are away.  You may not be able to sign for packages remotely but barring that this can be very handy.  Read more at The Register.

The Cougar 600M Gaming Mouse does well at adding functionality without going to the extremes some other models have. The sensor can be set up to 8200 DPI and you can also adjust the USB polling rate from 125Hz to 1000Hz, a nice feature for those who want to be able to have complete control over their input.  Those who love LEDs will like that the software allows you to toggle the lighting between 16.8 million colours as well as programming the eight buttons as single functions or macros.  How well does it game?  Check out the full review at Overclockers Club.

"The scroll wheel was an issue I only found from "longer" use, that I probably would not have noticed in a typical review testing time frame. After enough use, it started to squeak a bit, and in general make more noise. However, enough use later, and it's back to no squeak. It seems like it will be something that comes and goes. It still works, and that is most important."

NVIDIA's reported revenue of $1.15 billion just missed the analysts predictions, they saw an increase of roughly 4% from Q1 2014 but an 8% drop compared to the last quarter of 2014 which saw the release of the GTX 970 and the usual spike in sales from the holidays.  However when you look at net income, there was a drop of 2.2% compared to a year ago.  GPU sales made up the bulk of the income and are doing well as that division increased sales by 14% from last year bring in revenue 4.7% higher than last year.  Mobile Tegra sales saw a similar increase of 4.3% but the same can not be said for their LTE division, the Icera LTE modem unit is now on the chopping block, to either be dissolved or sold off.  You can get more numbers from this story at The Register.

AMD has provided information on their new Carrizo-L based 7000 series of chips featuring the A8-7410, A6-7310 and the A4-7210 as well as the E2-7110 and E1-7010.  The two E series chips replace the low powered Beema APS, the E1-6010 and E2-6110 which were found in All-in-One machines with the new E2-7110 being the first of that series to have four cores.  The other three models are new desktop chips with newer graphics cores, the full feature set you would expect and slightly higher TDPs than the E-Series.

The existing AMD A-Series Desktop APUs have seen a price reduction today with prices for the top end A10-7850K reduced to $127 with the low end A4-7300 costing a mere $42 which helps AMD's positioning as a supplier in the lower end of the market.  You can see the entire price list as well as some information about the new R300 series of GPUs in their post.

Raptr's Top PC Games of March 2015

Subject: General Tech | May 7, 2015 - 07:00 AM |
Tagged: raptr, pc gaming

Raptr is an application that helps PC gamers by optimizing in-game settings, recording and streaming gameplay, and providing a chat service. Each month, they use their community data to compile a list of most played PC games over the previous month. This release concerns the month of March, 2015.

raptr-caas-most_played_mar_2015.jpg

The top five games rarely move, but the last two months are minor exceptions. In February, Diablo III kicked Smite out of fifth place, leaving League of Legends, World of Warcraft, DOTA 2, and Counter-Strike: Global Offensive untouched above it. In March, DOTA 2 by Valve Software had its third place ranking usurped by their arch nemesis: Counter-Strike: Global Offensive by Valve Software. That is the only change in the top five segment.

Looking at the bottom three-quarters, Dragon Age: Inquisition continued its descent right off the list, allowing PAYDAY 2 and Spider Solitaire to both re-enter the top twenty. (Apparently Spider Solitaire dropping by the list made Raptr “sad”. It has been absent since November 2014.) Battlefield 4 is down and War Thunder is up. Battlefield Hardline was only tracked for the first two weeks after its release, because we ran out of March, but it didn't even come close to the top twenty, placing 49th. It is attributed to Battlefield 4's decline, though.

StarCraft II being the only exception, four of Blizzard's five current titles are in the top ten most played games on the PC. With the Legacy of the Void beta going on, I wonder if they will achieve a five-for-five (or six-for-six if Overwatch is available by then) when the game fully releases, whenever that is.
