  1. As much as I dislike Hillary (and the Clintons, in general), and with the experience I have with classified materials... *If* the information was classified long after the fact, I'm finding it hard to fault her (and this pains me to say). If it was classified at the time it was recorded, however, she should be prosecuted to the fullest extent of the law, as *anyone* read into a Secret, Top Secret, or any SCI (or higher) classification signs an NDA with the US Government, with serious consequences. Just look at Snowden, who has no political ties. Same consequences should apply if she knowingly let at-the-time classified data be stored on systems that weren't cleared for it...

  2. Uh, yeah... on In Memoriam: VGA (hackaday.com) · · Score: 1

    Well, I guess I'll need to find all-new DisplayPort or DVI or HDMI KVMs for my server farms. Hint: Ain't gonna happen. Any rack-mounted KVM I've found has only be VGA, as recently as last year. Even systems I'm speccing for server refreshes, all have VGA ports. It's gonna suck when VGA finally goes away, but at least in the headless server space, it doesn't seem soon...

  3. Anything is possible with the right budget... on Ask Slashdot: How Do You Store a Half-Petabyte of Data? (And Back It Up?) · · Score: 3, Informative

    Lucky (?) for you, I just went through purchasing a storage refresh for a cluster, as we're planning to move to a new building and no one trusts the current 5 year old solution to survive the move (besides which, we can only get 2nd hand replacements now). The current system is 8 shelves of Panasas ActiveStor 12, mostly 4 TB blades, but the original 2-3 shelves are 2 TB blades, giving about 270 TB raw storage, or about 235ish TB in real use. The current largest volume is about 100 TB in size, the next-largest is about 65 TB, with the remainder spread among 5-6 additional volumes including a cluster-wide scratch space. Most of the data is genomic sequences and references, either downloaded from public sources or generated in labs and sent to us for analysis.

    As for the replacement...

    I tried to get a quote from EMC. Aside from being contacted by someone *not* in the sector we're in, they also managed to misread their own online form and assumed that we wanted something at the opposite end of the spectrum from what I requested info on. After a bit of back and forth, and a promise to receive a call that never materialized, I never did get a quote. My assumption is they knew from our budget that we'd never be able to afford the capacities we were looking for. At a prior job, a multi-million dollar new data center and quasi-DR site went with EMC Isilon and some VPX stuff for VM storage/migration/replication between old/new DCs, and while I wasn't directly involved with it there, I had no complaints. If you can afford it, it's probably worth it.

    The same prior job had briefly, before my time there, used some NetApp appliances. The reactions of the storage admins wasn't all that great, and throughout the 6 years I was there, we never could get NetApp to come in to talk to us whenever we were looking for expansion of our storage. I've had colleagues swear by NetApp though, so YMMV.

    I briefly looked at the offerings from Overland Storage (where we got our current tape libraries), on the recommendation of the VAR we use for tapes & library upgrades. It looked promising, but in the end, we'd made a decision before we got most of those materials...

    What we ended up going with was Panasas, again. Part of it was familiarity. Part of it was their incredible tech support even when the AS12 didn't have a support contract (we have a 1 shelf AS14 at our other location for a highly specialized cluster, so we had *some* support, and my boss has a golden tongue, talking them into a 1-time support case for the 8 shelf AS12). We also have a good relationship with the sales rep for our sector, the prior one actually hooked us up with another customer to acquire shelves 6-8 (and 3 spares), as this customer was upgrading to a newer model. Based on that, we felt comfortable going with the same vendor. We knew our budget, and got quotes for three configurations of their current models, ActiveStor 14 & 16. We ended up with the AS16, with 8 shelves of 6 TB disk (x2) and 240 GB SSD per blade (10 per, plus a "Director Blade" per). Approximate raw storage is just a bit under 1 PB (roughly 970-980 TB raw for the system).

    In terms of physical specs, each shelf is 4U, have dual 10 GbE connections, and adding additional shelves is as easy as racking them and joining them to the existing array (I literally had no idea what I was doing when we added shelves on the current AS12, it just worked as they powered on). Depending on your environment, they'll support NFS, CIFS, and their own PanFS (basically pNFS) through a driver (or Linux kernel module, in our case). We're snowflakes, so we can't take advantage of their "phone home" system to report issues proactively and download updates (pretty much all vendors have this feature now). Updating manually is a little more time-consuming, but still possible.

    As for backups, I honestly have no idea what I'm going to do. Most data, once written, is static in our environment, so I can probably get away with infrequent longer retention period backups for every

  4. I haven't seen your house, but I'm betting that you have different types of trees planted on different sides, too. Say, deciduous trees for eastern/southern sides, and probably evergreens to the north. The deciduous provide shade and heat protection in the summer, but lose their leaves to provide light and some warming from the sun in the winter months, while the evergreens protect from northern winds.

    Am I close? This used to be standard practice to help use Mother Nature for natural cooling/heating.

  6. Well, my Nexus 6 hasn't pissed me off lately... on Ask Slashdot: What Are the Most Stable Smartphones These Days? · · Score: 1

    While I normally reboot all my devices at least weekly, I just noticed that, as of right now, and probably since I got the 5.1 update, my Nexus 6 has an uptime of over 624.5 hours, which is over 3 weeks. Color me surprised. My N7 2013 LTE crashed in the middle of doing stuff Thursday night, again with 5.1, so... I guess the N6 wins, in my book, for right now.

    As reference, whenever things get really wonky, and nothing else works, I power the devices down (as much as that pains me as a *nix sysadmin), and it seems to fix the problems. 3.7 weeks (and counting) seems to be an amazing run for current hardware/software combos.

    So, I'm torn... freedom vs health... where do I stand?! I... think I have to go with freedom here. I *chose* to stop consuming that crap. I don't want to force others down my path, as much as I honestly believe that it would help people. I'd rather people have the free will to choose, based on the evidence before them, but I'm too cynical to believe they will. I'd still like to naively think they will though, at least up until the point where their bad choices are costing *me* money...

  11. Re:This reminds me of a great Simpsons episode on EU's Top Court May Define Obesity As a Disability · · Score: 1

    Thyroid conditions account for maybe 10-15 lbs of weight gain, and can be medically treated after diagnosis from a competent medical professional.

    Thighroid condishuns, on the other hand, result in 100-150+ lbs of weight gain, are "impossible" to treat, and are 100% self-diagnosed.

    Every time I hear someone say they have a thyroid condition and that's why they're heavy, I ask what medication they're on. They never are, because they've never actually been diagnosed with a thyroid condition. (Google "fat logic")

    As a formerly obese person myself (and still about 6 lbs to go before I hit "normal" weight... *sigh*), just about any (especially obese people) *can* lose weight, just by changing what they eat. And by that, I mean what they *actually* eat, not their claim of "1 small salad then starve myself for the rest of the day while working out 4 hours at the gym every day".

    As an aside, the reference Simpsons episode, "King-Size Homer", has Homer gaining enough weight, in 1995, to be considered disable at *300 lbs*. Today, that's pretty much a commonplace weight in today's world. Think about that... A 239 lb Homer is "fat", and a 300 lb Homer is now "disabled", yet a good chunk of the population is already at or above those weights...
