It's Not a Car, It's a Self-Balancing Electric Motorcycle (Video)

johanwanderer Re:No (218 comments)

You do it in the same way everyone else who rides motorcycles do, with a tight turn :) and get out and push it back when you need to.

Comcast Predicts Usage Cap Within 5 Years

johanwanderer They have already done this a while back (475 comments)

A friend of mine already got hit with this 300 GB limit more than a year ago. At the time, I think they're just targeting their top 1% customers. Now they're just targeting the rest.

Autonomous Car Ethics: If a Crash Is Unavoidable, What Does It Hit?

johanwanderer The brake? (800 comments)

If a collision is unavoidable, they'd just brake as hard as they can without skidding, and hope the other side can maneuver out of the collision.

Wine On Android Starts Allowing Windows Binaries On Android/ARM

johanwanderer Re:Capt Keen (140 comments)

Just get DOSBox for Android. It should run Commander Keen without problems. I even booted Windows 3.11 on it just for kicks. Everything seems to work fine.

Largest-Yet EVE Online Battle Destroys $200,000 Worth of Starships

You should read the Doom Star series by Vaughn Heppner: Star Soldier. He have put a lot of thoughts into the matter.

23-Year-Old X11 Server Security Vulnerability Discovered

johanwanderer My XServers run on Windows (213 comments)

It's kinda funny, but all my XServers run on Windows these days, and only run once in a blue moon, so I can access that one or two stubborn applications that requires X. Not that it makes it less of an issue.

Astronomers Discover Largest Structure In the Universe

johanwanderer Re:Turtles, all the way up! (143 comments)

If you look further, you will find that there is a spherical structure with radius of approximately about 13 billion light years, and nothing outside of that.

OpenZFS Project Launches, Uniting ZFS Developers

johanwanderer Re:Advatages of ZFS over BTRFS? (297 comments)

I recently had a bunch of BTRFS failure on disks with heavy traffic. It's terrifying when you have to reboot any of those servers.

The only saving grace was the cluster was able to tolerate multiple block device failures, so I was able to reformat those disks using ZFS and resync the data.

To sum up, I experimented on an experimental file system, got burnt, and then switched back to ZFS. I didn't lose data, just time and frustrations.

Abandoned UK National Health Service IT System Has Cost $16bn... So Far

johanwanderer Re:Clinical records are hard (220 comments)

Another use of the paper record is when they need to re-input all that into the new systems they upgrade to.

It sounds like a joke, but it's not. Happens all the time. These office systems are so obscure that the new vendors often time don't even bother to migrate the data, forcing manual data entry for all the relevant records. It's very sad.

It's the same when these "office" systems have thousands of connected offices. Each would still have to re-enter its records.

How the UN Might Have Inadvertently Started a Cholera Epidemic In Haiti

johanwanderer Re:UN's Fault? (158 comments)

I fail to believe that Cholera is absent from Haiti before hand. It's something that most people (read tourists) carry, and it's presumed to be everywhere.

3D Printing In Gel Enables Freeform Design and an Undo Function

johanwanderer Re:resin+gel as support material (33 comments)

This allows you to print "unbalanced" objects, e.g. those that would tip over when you print layer-by-layer.

New Thermocell Could Turn 'Waste Heat' Into Electricity

johanwanderer Re:Mod parent up (181 comments)

Let's supposed your "final" exit temperature is 90C. Also let's assume the cooling reservoir is around 10C. Let's also assume that the final stage takes steam from 200C down to 90C. That give it a theoretical Carnot limit of 110/363 ~ 30%.

From the article, "The device offers the possibility of a cheap and flexible design suitable for harvesting waste heat in the 100- to 200-degrees Celsius range.". Assume it really work all the way to 10C, that could theoretically be 190/283 ~ 67%. If their efficiency is higher than a turbine, then they can use that to replace the last turbine stage. If not, then there is nothing to see.

I think the news here is that they *might* have come up with a better device than a low temperature turbine.

Linux 3.11 Features Fall Into Place With Merge Window

johanwanderer Re:Motif window manager? (70 comments)

I actually install mwm (Open Sourced now) on lots of headless machines nowadays. I found it to work very well over VNC. Much better than a lot of the alternatives. And yes, I use VNC, because X over VPN is just painful.

The people on xda-developers have been doing that for ages. That's how they mod the official APKs and change images to match the various themes.

Team creates multicellular life in the lab

After sixty one-day cycles of selecting for clustering behavior, they managed to create hundred-cells clusters. The cells are "related", and remain attached even after cell division."

BD+ Virtual Machine Cracked

johanwanderer johanwanderer writes  |  more than 6 years ago

johanwanderer (1078391) writes "ExtremeTech and ArtTechnica is reporting that SlySoft, a developer of DVD cloning software, claims to have completely cracked the BD+ DRM protocol guarding Blu-ray discs. The ExtremeTech article can be found here: http://www.extremetech.com/article2/0,1558,2277472,00.asp?kc=ETRSS02129TX1K0000532 And its content is as follow: SlySoft, a developer of DVD cloning software, claims to have completely cracked the BD+ DRM protocol guarding Blu-ray discs. BD+ is a small virtual machine environment included on Blu-ray discs; HD DVDs lacked the feature. Last year, SlySoft said it had hacked the BD+ environment to allow encoded movies to be ripped to a hard drive and viewed using a specific version of its CloneDVD software. Now, SlySoft is claiming that version 6.4.0.0 of its AnyDVD HD program has completely broken the BD+ copy protection, allowing transcoding of the video into an unprotected form. About a year ago, SlySoft cracked HD DVD. "Admittedly, we are not really so fast with this because actually we had intended to publish this release already in December as promised," Peer van Heuen, head of High-Definition technologies at SlySoft , said in a statement. "However, it was decided for strategic reasons to wait a bit for the outcome of the "format war" between HD DVD and Blu-ray. "On top of that, we first wanted to see our assumptions confirmed about the in the meantime released BD+ titles regarding the BD+ Virtual Machine," van Heuen added. "We are rather proud to have brought back to earth the highly-praised and previously 'unbreakable' BD+. However, we must also admit that the Blu-ray titles released up to now have not fully exploited the possibilities of BD+. Future releases will undoubtedly have a modified and more polished BD+ protection, but we are well prepared for this and await the coming developments rather relaxed." Theoretically, the BD+ code can be replaced if a player manufacturer discovers that the player has been hacked. However, it wasn't clear at press time whether the AnyDVD HD release would either prevent the modified BD+ code from being overwritten, or whether an updated release would be be necessary, as van Heuen seemed to imply."

A Two-Time Universe?

johanwanderer (1078391) writes "A Two-Time Universe? Physicist Explores How Second Dimension of Time Could Unify Physics Laws... For a long time, Itzhak Bars has been studying time. More than a decade ago, the USC College physicist began pondering the role time plays in the basic laws of physics the equations describing matter, gravity and the other forces of nature. PhysOrg reports on how a second time dimension could solve the problems with current theories."

johanwanderer (1078391) writes "In March 2007, scientists may have discovered a new state of matter, leading to more fundamental understanding of the universe, that it may be a string-net liquid. An experimental solid, coined herbertsmithite contains an electron arrangement that was previously deemed imposible. It is theorized that electrons (and other more fundamental particles) are end points of strings (thus explaining entanglement) in a string-net liquid."
