Harvard's CompSci Intro Course Boasts Record-Breaking Enrollment

johanwanderer Re:Linux, cryptography, HTML and JavaScript. (144 comments)

It's CS50. It's not even a 100-level classes. This is their way of saying, pay us $X for 3 course credits and see if you would even like to continue down this path.

The title should be: 1 in 8 Harvard students hopelessly undecided about Computer Science.

Power Grids: The Huge Battery Market You Never Knew Existed

johanwanderer Re:Pumped storage and transport (245 comments)

I'm just curious about the "C" shaped canal idea. What is the advantage of it? And what is the use-case that you envisioned?

Facebook Seeks Devs To Make Linux Network Stack As Good As FreeBSD's

johanwanderer Why not just use FreeBSD then? (195 comments)

It might be a silly question, but why don't they just use FreeBSD in that case?

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.

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

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.

Team creates multicellular life in the lab

johanwanderer (1078391) writes "A team of biologists from the NSF has successfully created multi-cellular life using brewer's yeast. 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."
