Comment Re:Home server not the fix-all (Score 1) 166

Seconded. I've been doing the same, since 1999. Web spiders are responsible for most of my upstream bandwidth, and I only notice when I'm looking at the log files. None of the 4 ISPs I've had over the years have complained or blocked my service.

The only actual problem I've had is email deliverability. Most destinations would bounce my emails because they came from a Dynamic IP. I configured Postfix to forward everything through Time Warner's mail servers, and I haven't had problems since.

Comment Re:Nintendo's taking a lot of flak for this... (Score 1) 156

I know I'm late to this thread, but I didn't see anybody else say this.

After my son had corrective surgery for a crossed eye, the surgeon warned us that artificial 3D would inhibit his development of real 3D. He was born with the crossed eye, so he never had stereoscopic vision. It took about 6 months after the surgery to get a bit of depth perception, and about 18 months before he could pass all of the 3D vision tests.

Once he passed all the vision tests, the doc said to avoid artificial 3D, because it could cause the eye to re-cross. Now he's at an in between age when a re-crossed eye could cause him to lose stereoscopic vision permanently. If it re-crossed, and was left untreated for long enough, there's a risk that his brain is flexible enough to drop the neural paths, but not retrain when stereoscopic vision is surgically restored. ie, a very small risk. At some point (16 I think?), he'll be old enough that it's not likely to happen anymore. Given the relative risk/reward of artificial 3D, it's not worth even the tiny probabilities involved.

Yes, there are technical work arounds (ThinkGeek sells some "2D" 3D glasses). If it was something useful, I'd do it, but artificial 3D isn't worth the effort.

Full disclosure: I don't like artificial 3D. I can see full 3D, and I'd still buy a 2DS over a 3DS.

That is true for both HDD and SSD, it's just less common to use it for HDDs. IIRC, 10% of the HDD platter is reserved for sector re-mappings. HDDs usually reserve re-mapping events for things like starting-to-fail sectors and bad sectors created during manufacturing. SSDs use re-mapping to prevent flash wear.

When I wipe an HDD or SSD, it's because they've been replaced after failing SMART. The SMART attribute Reallocated_Sector_Ct tells me how many HDD sectors had my data, but are no longer accessible to me. Some of my older SSDs have a low double-digit Reallocated_Sector_Ct value. That indicates that these SSDs only increment that attribute for re-maps due to failing sectors rather than wear leveling.

For what it's worth, I had that problem until I added much more RAM than I thought I needed.

My original setup, I had 10GB of RAM, used about 4GB in various Mac apps. If I ran a VM that needed 1GB of RAM, the machine was sluggish. Pause the VM, the host sped back up. I tried adding a second HDD, and moving all the VMs onto it. It helped some. The BBOD didn't stick around as long, but the host OS was still annoyingly slow.

Later I needed to run a couple more VMs full time, using an additional 4GB of RAM. I added 16GB of RAM (had to remove 2GB, ending up with 24GB of RAM). Now I can run at least 4 VMs full time, all of them using about 10GB of RAM, without any noticeable host slow down.

Submission + - PCI DSS: is the cure worse than the disease? (techworld.com)

An anonymous reader writes: Complying with the Payment Card Industry Data Security Standard (PCI DSS) is prohibitively expensive, and the cost of compliance bears very little relation to the cost of a breach, according to Dave Birch, director of IT consultancy Consult Hyperion. Speaking at a Westminster eForum on the future of digital payments, Birch said that, while data driven identity fraud accounts for the overwhelming majority UK fraud, PCI DSS may not be the best solution in the long term. “The cost of PCI DSS compliance has turned out to be a cure that's worse than the disease,” said Birch. “It's not transparently obvious to me that it makes sense to continue it indefinitely far into the future. I think PCI needs as much of a rethink as the payments security itself does.”

I think it indicates that somebody can discuss online, without tainting an identity so badly that it must be abandoned. Do you find yourself spouting inflammatory, idiotic, and racist arguments at your real-life neighbors, then decide it's time to move? My /. account is like a phone number, email address, or street address. I suppose it helps that I'm naturally a lurker.

Don't get me wrong, I've said some stupid shit.

For example if I designed a pencil balancing on its tip with no supports, does the software, or somebody at shapeways, alert me that I'm being stupid?

That shouldn't be a problem. If you watch the video in TFA, the item is built up layer by layer, supported by un-fused stock. Your pencil balancing on it's tip will be supported by surrounding material, until it's finished and removed. At which point it won't be balanced on it's tip anymore. This is how they build hollow pieces, and pieces with overhangs.

As the sibling poster mentioned, they do check for other things. Like they make sure that hollow items aren't too thin, connecting struts actually connect, etc.

Comment Re:ESXi (Score 1) 320

I wouldn't run my ntp masters on ESXi. I've always let my firewalls and/or routers handle that task, so I haven't needed to virtualize. On the VMs themselves, monitor to make sure ntpd is running (or set your config manager to start it if it's not running). I've had some problems where one VM causes slowness for the others, and ntpd would loose sync and exit.
