Comment Real liberals need to stop this (Score 5, Insightful) 666

I have found lately that when I ask my liberal friends about this phenomenon (the erosion of free speech on college campuses by Generation Butthurt), they either feign ignorance or say that "it's no big deal" and quickly change the subject to whatever evil they think the Republicans are pulling lately. This is weak, and frankly I don't know how a true liberal would stand for such an encroachment on their own civil liberties. If these opposing views are so terrible, let them out there to be discussed and torn apart on the public eye, and force those espousing them to defend their viewpoints. Of course, that means you have to be able to defend your viewpoint as well, which is what this is all about.

Comment Re:RAID 0 is not for anything you don't want to lo (Score 2) 73

I have found these calculators work well for projecting the performance and capacity of various RAID levels:



Some other guy mentioned RAID 10 isn't a backup strategy; he's correct (no RAID level is), however one thing to keep in mind is that when his RAID 0 array dies, he'd better hope his back-ups are all up-to-date and restorable. With just about any other RAID level, you get an opportunity to replace the dead / dying drive first, start rebuilding, and KEEP ROLLING, with no need to screw around with backups at all and no human interaction even required if your array has a hot spare configured. Yes, technically that is availability, but I'd sure as hell take it over "fuck, there went one drive of my RAID 0 stripe, better hope I can tolerate this downtime and that my last backup set had everything I needed on it." RAID may not be a backup strategy but it's absolutely another layer in place before you need to restore from backups (as long as it's not RAID 0).

Comment Re:10GbE isn't that interesting (Score 2) 98

SMB3 Multichannel isn't the same as link aggregation. It assigns CPU cores to process SMB transfers as they come across the wire(s), thereby handling one of the real-world bottlenecks (i.e., that the client typically chokes trying to process all of that inbound data coming off of the fast pipe).

Comment Re:10GbE isn't that interesting (Score 2) 98

That's cuz you're not doing it right. Having dual 10GbE ports on each end will let you run SMB3 Multichannel for network transfer speeds that will outpace anything but the fastest RAID arrays. We're seeing real-world file transfer speeds of over 1.3 gigabytes (not gigabits) / second over copper Ethernet. I'm seldom a Microsoft advocate but it is awesome.

Submission + - Phase One Begins Shipping 100 Megapixel Camera System

An anonymous reader writes: Danish camera manufacturer Phase One has released its latest medium format digital back: the IQ3 100MP, a 100 megapixel full-frame unit with a native resolution of 11,608 x 8,708 16-bit pixels and 15 stops of dynamic range. The sensor, which was co-developed with Sony, is a CMOS chip, which means that it is much faster than those in Phase One's previous top-of-the-line CCD-based digital backs. This cutting edge technology doesn't come cheap, though: with a camera body and 50mm equivalent lens, this baby will set you back $48,990 USD.

I'll do you one better. The budget of the ENTIRE Smithsonian Institution for fiscal year 2015, the world's largest museum and research complex, is $819.5 million. This includes salaries and expenses of $675.3 million. You could fund all 19 Smithsonian museums and the National Zoo for over 5 years for what this ship costs.

Comment This is an enterprise-class drive (Score 1) 145

To be clear: most people buying these types of drives don't buy them one at a time to be shoved into a workstation, or even to be used as a backup. They buy 10+ or more at a time to assemble into some sort of RAID. They are most likely looking to maximize available terabytes per rack unit in a datacenter. Things like cost are secondary in these scenarios -- it costs what it costs. 7200RPM is great, especially when a large number of drives are striped together with RAID 10 or something similar (because with RAID 10, the more drives you add, the faster things go). Latency? Meh, we'll front-end the array with a nice SSD-based read-write cache (also RAID10), usually one that's managed right from the same controller card. And like most new enterprise-class drives, these have SAS3 interfaces -- that's 12 Gb/S. With arrays built with these drives, your network bandwidth and OS offload likely become the bottleneck very quickly. Make no mistake -- the target buyer is someone who wants to build very dense, fast, large arrays of drives -- think JBOD for virtualization, or a huge fast fileshare box with a bunch of fast NICs, or a big database instance, etc. So -- until SSDs come in these capacities -- just because *you* won't use this in your gamer rig / IDE / whatever, doesn't mean there isn't a market for huge, relatively fast spinning rust drives.

Comment What about SAS3 / 12 Gbps? (Score 1) 67

8 TB on a single SSD is great and all, but I'd rather that the flash manufacturers focus on moving their mainstream interfaces over to SAS3 like the enterprise storage world has done. What good is all of this fast storage on a single drive if you're capped by the bandwidth of the drive's interface?

Comment After the Mozilla fiasco, they will be careful (Score 5, Insightful) 130

After the demonization of Brendan Eich for his personal donation in support of CA Proposition 8, the writing is on the wall. You can expect that most big tech donors of all stripes, regardless of party or political stance, will donate to political causes through the Super PAC of their choice.

Comment Re:Business model? (Score 3, Informative) 346

what evidence do you have that the politicians have been bought off?

I'm glad you asked, as that gives me a great reason to post a link to Simon Garber. As Wikipedia says, "While in Russia in 2001, Garber became friends with Patrick Daley, the son of long-time Chicago mayor Richard M. Daley. City officials tightly regulate all aspects of medallions ownership, granting permission to purchase medallions on an individual basis. Within a year of meeting Patrick, Garber quickly acquired over 300 Chicago taxi medallions. Garber also hired Mayor Daley's former chief of staff Gery Chico as a City Hall lobbyist. In 2003, Garber used this political capital to start the Chicago Carriage Cab Company and was granted permission to operate the taxi business in Chicago. Within six years, the Chicago Carriage Cab Company had amassed over 800 medallions, making it the largest taxi company in the city."

This is but one example, from one city. A little Googling will easily reveal many more examples.

Comment Re:Business model? (Score 1) 346

And yet, tens of millions of people around the world think it's safe enough that they use rideshare apps over and over, every day. And tens of millions more think that they make enough money doing it that they choose to keep driving for Uber, and Lyft, and the other rideshares. Why? Because to them, it's better, cheaper, and more convenient than regular taxis.

Call Uber all the names that you want, but the taxi companies better figure out that they've got to compete with the rideshare services or they'll soon be obsolete. You can't litigate away technological advances, nor can you prop up a dying business model forever. The rideshare genie is out of the bottle and he's not going back in.
