Submission + - PCGamingWiki looks into Linux gaming with Port Reports (

AberBeta writes: PCGamingWiki contributor soeb has been looking into the recent larger budget game releases to appear on Linux, including XCOM: Enemy Unknown & Borderlands: The Pre–Sequel produced by Mac porting houses Feral and Aspyr, and finds that while feature parity is high, performance could be a smidge better. However people accept the performance differences, the games are arriving, now the userbase needs to expand to make a virtuous cycle.

Submission + - Ask Slashdot: Bitcoin over Tor is a bad idea? (

jd writes: Researchers studying Bitcoin have determined that the level of anonymity of the cryptocurrency is low and that using Bitcoin over Tor provides an opportunity for a Man-in-the-Middle attack against Bitcoin users. (I must confess, at this point, that I can certainly see anonymity limitations helping expose what machine is linked to what Bitcoin ID, putting users at risk of exposure, but I don't see how this is a function of Tor, as the paper implies.)

It would seem worthwhile to examine both the Tor and Bitcoin protocols to establish if there is an actual threat there, as it must surely apply to any semi-anonymous protocol over Tor and Bitcoin has limited value as a cryptocurrency if all transactions have to be carried out in plain sight.

What are the opinions of other Slashdottians on this announcement? Should we be working on an entirely new cryptocurrency system? Is this a problem with Tor? Is this a case of the Scarlett Fish (aka: a red herring) or something to take seriously?

Submission + - Detritus from cancer cells may infect healthy cells (

bmahersciwriter writes: Tiny bubbles of cell membrane — called exosomes — are shed by most cells. Long thought to be mere trash, researchers had recently noticed that they often contain short, regulatory RNA molecules, suggesting that exosomes may be one way that cells communicate with one another. Now, it appears that RNA in the exosomes shed by tumor cells can get into healthy cells and 'transform' them, putting them on the path to becoming cancerous themselves.

Submission + - Prison Architect prison simulation game launched for linux (

An anonymous reader writes: Prison Architect is a Prison Simulation and Management game currently released in Alpha from indie developers Introversion Software (Uplink, Darwinia, DEFCON and Multiwinia). Prison Architect was initially released in September 2012 and has been played by nearly 90,000 gamers so far. 10 Alpha updates have been released and Introversion is committed to continuing to release a major update each month. From Alpha 10 onwards Prison Architect will be available for Linux — from the Introversion Blog:

"We are now supplying builds for Linux via steam and as a standalone download from our website. The game should be widely compatible across the various Linux distributions, but please let us know if you have problems by logging bugs in our bug tracker. We have targeted Ubuntu 12.04 (32 bit and 64 bit) as a starting point, and we anticipate wider compatibility in later alphas. Please note that we do require glibc 2.15 or later, which unfortunately means Prison Architect does not currently work on Debian Stable."

You have to understand terminal ballistics to understand why they changed from MP5s to rifles(M16/M4/whatever). The 9mm round actually has a higher chance of over-penetrating a target than a .223 even though it has far less power. The .223 tends to fragment and tumble while the 9mm stays solid and passes through in roughly a straight line; possibly hitting someone behind them. This is research which has been done on statistics over the last 20 years from dozens of countries' police forces which is why you see the change moving away from sub-machineguns all over and not just in a single country.

Comment Re:KSP FTW (Score 1) 64

I've been playing KSP for a while too and it's a fantastic game. The reason you can't do Lagrange points is that it uses patched conics which does "spheres of influence" around planetary bodies and doesn't do gravity interpolation. That being said, the math was good enough to get us to the moon, so for a game as fun as KSP I'm not too upset.

In the book series The Night's Dawn Trilogy space combat was between manned ships which launched weapons drones. They were nothing more than a navigational computer strapped to an engine with lots of sub-munitions(nukes, kinetic projectiles, bomb pumped lasers, and ECM pods). They'd fly around with pretty realistic physics and launch swarms of the drones at each other, along the most probable paths the other ship would take, and then the drones would just fly in and shotgun all their munitions in the hopes of saturating the area enough so that one or two would hit even with the other ship firing countermeasures and maneuvering. It was pretty much all a game of probabilities.

Man Orders TV On Amazon, Gets Shipped Assault Rifle 666

First time accepted submitter InfernoApple writes "Seth Horvitz, a Northeast D.C. resident, thought he had ordered a new high-definition television a few days ago through from a third-party merchant. When the package arrived yesterday, however, Horvitz opened the oddly shaped box to find something completely different. Instead of the flat-panel TV he had bought to enjoy with his wife, who is pregnant, Horvitz opened the long packaging to discover a Sig Sauer SIG716, a high-caliber, semi-automatic assault rifle capable of mowing down, well, just about anything."
