Same conclusion. It's too easy to feel that precarity from the early computing age (not enough storage! not enough cycles! data versions of things are special!) if you were there. I think there's some of that going on here on Slashdot a lot of the time.

People in love with old Unix boxen or supercomputer hardware. People that maintain their own libraries of video, but all that's stored there is mass-market entertainment. And so on. It's like newspaper hoarding.

Storage and computation are now exceedingly cheap. 8-bay eSATA RAID cases run a couple hundred bucks, new. 4TB SATA drives run less than that. With 6 raid ports on a mainboard and a couple of dual- or quad-eSATA port PCI-x cards, you can approach petabytes quickly—and just for four digits. The same goes for processing power—a dual-processor Xeon setup (in which each processor can have core counts in the double digits) again just runs $couple thou.

And data is now cheap and easy. Whatever you want—you can have it as data *already*. Movies? Music? Books? Big social data sets? They're coming out our ears. The investment of time and equipment required, all in all, to put yourself in a position to rip and store a library of "every movie you've ever rented," and then actually do so, is much larger than the cost of simply licensing them via streaming. The same goes for music, ebooks, and so on.

There's just no need. Even my desktop is now starting to feel obsolete—for the work computing I do, there's a good chance I'll just go to Amazon cloud services in the next year or two. At that point, an iPad, a wireless keyboard, and a couple apps will probably be all the computing power I need under my own roof. If I have a desktop, it'll just be to connect multiple monitors for screen real estate.

Comment No datacenter. Just a desktop computer (Score 1) 287

with 20 cores, 128GB RAM, 48TB online storage, and gigabit fiber coming in.

Yes, I use all of it, for work. But it's definitely not a "data center." These days, I don't know why anyone would want one—even moderately sized enterprises are increasingly happy to pay someone else to own the data center. Seems nuts to me to try to bring it into your basement.

If you just need the computation and/or the storage, desktops these days run circles around the datacenter hardware from just a few years ago. If you need more than that, it's more cost effective and reliable to buy into someone-or-other's cloud.

Comment Why do this? (Score 4, Interesting) 287

I sort of don't get it. White box PCs with many cores, dozens of gigabytes of RAM, and multiple gigabit ethernet ports cost next to nothing these days with a few parts from Amazon.com. If the goal is just to play with powerful hardware, you could assemble one or a few white box PCs with *many* cores at 4+ GHz, *tons* of RAM, gigabit I/O, and dozens or hundreds of terabytes of online RAID storage for just a few thousand, and plug them straight into the wall and get better computation and frankly perhaps even I/O performance to boot, depending on the age of the rackware in question.

If you're really doing some crazy hobby experimenting or using massive data storage, you can build it out in nicer, newer ways that use far less (and more readily available) power, are far quieter, generate far less heat, don't take up nearly the space, and don't have the ugliness or premium cost spare parts of the kinds of gear being discussed here. If you need the features, you can easily get VMware and run multiple virtual machines. 100Mbps fiber and Gigabit fiber are becoming more common and are easy to saturate with today's commodity hardware. There are an embarrassment of enterprise-ready operating systems in the FOSS space.

If you really need high reliability/high availability and performance guarantees, I don't get why you wouldn't just provision some service for yourself at Amazon or somewhere else and do what you need to do. Most SaaS and PaaS companies are moving away from trying to maintain their own datacenters because it's not cost effective and it's a PITA—they'd rather leave it to specialists and *really big* data centers.

Why go the opposite direction, even if for some reason you really do have the need for those particular properties?

The cracking would take longer than the expected lifespan of the universe.

The obvious solution is inter parallel universe travel. We find the parallel universe in which the only difference is that the suspect didn't lock his/her phone and get the data there. Problem solved.

I was a kid I've had this deep love and passion for astronomy and astrophysics. This love and passion though never evolved into any formal education or anything beyond just a distant fascination as I got out of high school, into college ...

So which is it, a "deep love and passion" or "distant fascination"? If the former, your life mistake was not pursuing it in college, etc... If simply the latter, then read a few books about it as a hobby. Either way, with two kids and a full-time job, you probably don't have the time and determination to learn enough to "start contributing back to the field" - at least, not anytime soon.

Astronomy and/or astrophysics is not just something you pick up over the weekend. As someone once said, "Traveling through hyperspace ain't like dusting crops, boy!"
