Sandia's Floating, Dust-Free, Spinning Heatsink

casualsax3 Re:until it crashes (307 comments)

Mechanical hard drives still rely on heads that float over the platter. These days they're built to operate an order of magnitude closer to the platter than 10-20 years ago - around 10 nanometers. The platters now spinning so fast that the head is also able to self regulate its height based solely on airflow dynamics and downforce. Small bumps and drops are not sufficient to break through the cushion of air created by the head moving over the platter at 80+ miles per our. Interestingly the force also works in the other direction, preventing the head from rising to high. You can picture it working like a magnet fixed in place over a superconductor, only this is obviously using a different force to accomplish the feat. For extreme bumps and drops, hard drives (particularly laptop hard drives) have accelerometers that can detect a drop or bump and call the head back to its resting place before it has a chance to smash into the platter.

TSA 'Warning' Media About Reporting On Body Scanner Failures?

casualsax3 Re:Easy fix? (465 comments)

No, I think the entire program should be scrapped both because of the health hazards, and because it's a gross invasion of privacy. If they're hell bent on keeping it around though, the least they could do is make it work properly. I'd rather be exposed to a double dose of radiation if it actually made me safer, as opposed to the status quo which is one shot for theater's sake.

casualsax3 Easy fix? (465 comments)

Aside from just scrapping them entirely, wouldn't this be a non-issue if they just had the traveler rotate 90 degrees and repeated the scan?

Leaked AT&T Letter Damages Case For T-Mobile Merger

casualsax3 Re:US cell system (201 comments)

I was a recent visitor to the USA and was astonished at the 3rd world nature of its cell system. I had never imagined it was so bad, before visiting.

What exactly did you find so subpar? Service from just about any carrier should have been good considering you were in a city with a subway. My experience with world phones in Europe wasn't exactly thrilling. I bought a sim in London and then got to pay 2 pounds per day just to turn it on in Spain. What union/country/territory do you live in who's carriers have seemingly gotten it so right?

iOS 4.3.4 Prevents Hacking and Jailbreaking

casualsax3 Re:aaaand... (281 comments)

From TFA:

Of course, you should still stick with 4.3.3 if you don't want to bother with re-jailbreaking anytime your phone shuts off.

Or you should not buy an iPhone in the first place. Give your money to a vendor who deserves it.

Flash On Android Fails To Impress

casualsax3 Re:flash without flashblock is idiotic (436 comments)

All of the existing Android implementations of Flash behave like this. On my Viewsonic GTablet, Flash 10.2 defaults to loading On Demand (ie you click play) in both the default browser and alternate browsers like Opera Mobile.

Earth's Inner Core Rotation Slower Than Estimated

Preventing My Hosting Provider From Rooting My Server?

casualsax3 Re:You're complicating things. (539 comments)

They offer KVM access, at $35.00/day, which in this case I refuse to pay to fix what they broke, outside of the context of the server.

Stop being stubborn - why not KVM in, prove it's their fault, and then make them reimburse you for it?

Alternately, they want me to hand over the root password (not a privileged account, but THE root password), so they can do it themselves.

Sounds like you're either incapable or unwilling to fix the problem yourself, but at the same time you refuse to let them do it? What exactly would make you happy here? And don't say "moving me back to the old hardware and datacenter that I was paying for!" Be realistic.

Only a few days ago, they indicated that the NIC on the server may be causing the issues. I'm down 2-3 hours every other Sunday because of this.

You said yourself that it's new hardware. It's completely reasonable for them to suggest you've got a bad NIC driver in there for whatever card you were moved to.

...every other Sunday between 7:00am and 8:00am EST, my server's load goes over 100 as incoming connections spike over 700/sec., sendmail refuses connections due to the load, and the box seizes up. The logs show that the connections are established and then hang.

This is almost certainly a problem on the system itself. I've seen a handful of cases where hardware load balancers in DSR mode can lead to connection pileups under certain conditions, but 99% of the time it's a problem on the server itself. In any event, tuning should be able to prevent that from knocking the box over completely, allowing you to stay logged in and see what's going on.

Also, by claiming that nothing has changed on the system, you're either lying, or you're a horrible sysadmin who doesn't apply updates. Another potential scenario I see here (obviously aside from new hardware using previously unused drivers...) is that you or your package management system installed a new kernel or NIC driver, but never rebooted. Then when the server was powered off and migrated to the new facility, it came back up with the new (and potentially problematic) driver/kernel.

Preventing My Hosting Provider From Rooting My Server?

casualsax3 You're complicating things. (539 comments)

Switch providers. Plenty offer remote reboot and serial console or KVM for both VMs or physical servers, which would allow you to go crazy with custom encrypted partitions etc. At the end of the day though, someone somewhere at the hosting company is still going to be able to reboot your server into a rescue environment and reset the root password. Go colocation if you're really that paranoid about it.

You also have zero chance with litigation, unless you've somehow gotten them to sign something saying they specifically won't muck around in your server.

I'd also like to know how you *know* it's a hardware or network issue outside of your server. How do you know it's not your NIC driver hanging up? Older e1000 drivers (super common card in the hosting industry) are quite flaky. What research have you done outside of your internal monitoring?

How to get around ISP port blocks?

casualsax3 casualsax3 writes  |  more than 5 years ago

casualsax3 (875131) writes "I'm going to be moving soon, and my new apartment comes with Optimum Online. I have a share on a Windows server that I need to get to over the Internet occasionally, and I just found out that Optimum blocks port 445 across their entire network in New York City (and perhaps elsewhere?). I have two laptops that run Linux, and one always-on desktop that runs Windows. What's the best way to get around the block and get to the share in Linux and in Windows?"

Tips for taking your laptop in and out of the US?

casualsax3 casualsax3 writes  |  more than 5 years ago

casualsax3 (875131) writes "I'm going to be taking a week long round trip from NYC to Puerto Vallarta Mexico sometime next month, and I was planning on taking my laptop with me. I'll probably want to rip a few movies and albums to the drive in order to keep busy on the flight. More important though, is that I'm also going to be taking pictures while I'm there, and storing them on the laptop. With everything in the news, I'm concerned that I'll have to show someone around the internals of my laptop coming back into the US. The pictures are potentially what upsets me the most, as I feel it's an incredible violation of my privacy. Do I actually need to worry about this? If so, should I go about hiding everything? I've heard good things about Truecrypt. Is it worth looking into or am I being overly paranoid?"

Top Five Lies In The Managed Hosting Industry

casualsax3 casualsax3 writes  |  more than 6 years ago

casualsax3 (875131) writes "Who knows what really goes on in the world of dark fiber and datacenters? The confusion surrounding the inner workings of this industry gives hosting companies the opportunity to dupe customers with fake promises. Unfortunately, this is common within the industry. In today's digital era, every company needs managed hosting, but figuring out which offerings are realistic and critically important for optimum service is difficult. Here are the top five lies in the industry."
