I just read a history of the Mississippi before the Civil War and I seem to remember something about large bones being discovered in giant burial mounds found near the flood plain.
I think they also mentioned that before the Corps of Engineers "tamed" the Mississippi (ie, turned it into an navagation canal) the regular flooding and natural erosion of the wild river would periodically expose giant bones, although those I believe were attributed to dinosaurs.
Wow, that is impressive. I doubt I'll ever see that much write intensive flash in one place. We added a flash tier to a seed install (dumb customer only bought a single 15k tier and wondered why performance sucked) and I can never get over how fucking outrageously expensive the flash tier costs. I think it was pushing $100k.
I'd wager that mid range flash like the Samsung 850 Pros are getting cheap enough that double parity, double hot spares and replacing disks regularly due to burnout is probably cheaper for nearly the same performance than buying write intensive flash for all but the most intensive applications.
It's too bad that inexpensive SAN controllers rely on such cheap processors and NICs. I think it's getting to the point where fairly dumb controllers and bulk prosumer ssds will outperform tiering controllers.
It's a good question and I can't say why for any concrete reason other than the vibe I got from her personally and knowing her boyfriend.
She struck me as a pretty demure; she didn't give off any kind of a sexual vibe or even that she was especially outgoing or adventerous. I just didn't believe she had the personality type that would be at all likely to get drunk and have a one night stand, especially with a coworker and especially not cheating on her boyfriend.
I didn't get a "blow by blow" account of her experience, but the same kinds of personality traits made me believe that once she woke up with the guy pulling her pajamas off she probably just kind of laid there and let him do what he wanted.
I've only had one other woman tell me about being raped in detail and what she described was pretty much the same. A guy knocked on her door, forced his way in and the shock and the fear were so great that she basically just went limp and he raped her and left. It was literally over in under five minutes, including the minute ripping her clothes off and pulling up his own pants.
I'm guessing this is pretty common for many rape situations. The expectation of fighting and screaming is probably less realistic than just freezing from fear. There may also be some fear that if they struggle that the guy will beat the shit out of them and that the intercourse will be even more painful.
Rightly or wrongly, the police may be influenced by their familiarity with the criminal justice system and circumstances that were reported. So many rape accusations boil down to a he said/she said situation that would be impossible to get charged by a prosecutor, let alone result in a convicton in court.
A woman I used to know was raped by a coworker. The woman and her roommate were waitresses at a restaurant and bar. They had the company Christmas party at the restaurant and the rapist was one of the employees. Everyone had too much to drink and the rapist was too drunk to drive and asked if he could crash on their couch. They said sure. In the middle of the night, he crept into her room and raped her and left the apartment afterwards.
In the morning, she told her boyfriend who insisted she go to the police who were basically dismissive of the claim, not because they thought she was lying but because there was no way to conclusively prove it was rape. There were witnesses who saw the three of them (the woman who was raped, her roommate, and rapist) voluntarily leave together. All had been drinking. The apartment wasn't forcibly entered. The rape itself didn't involve enough violence that she had bruises, scarring or signs of a physical struggle.
The cops said they would bring him in for questioning but that unless he actually admitted raping her outright, what would almost certainly happen is that he would say that after they got back to the apartment she invited him into her room for sex and that he left afterwards and that the rape accusation was that she felt guilty because she had a boyfriend. And because there was no way to disprove this version of events, the prosecutor wouldn't even file charges. They also said the presence of the roommate would work against her, since he would claim that since her roommate didn't wake up she wasn't fighting or resisting.
Are the cops insensitive? Maybe, but what can they do when there's no evidence?
I believed her personally because I knew her fairly well, but if I think about it too long even I can start to enterain doubts. Why was there no physical struggle? Why didn't she yell and wake her roommate? If I was a cop confronted with this a lot, I can see why they come off indifferent.
We sell and install Compellents where I work and AFAIK the models with flash tiers are marketed at 300k IOPS max. 1M IOPS sounds like a benchmarking flaw.
Maybe it would be possible to get 1M with multiple SSD enclosures uitlizing multilple SAS backend loops, but something tells me it would have to represent the sum of many workloads, not what would be possible for a single workload once you account for some latency associated with synchronizing dual controllers and the front end fabric connectivity limitations and RAID computation. Plus it would be outrageously expensive.
But the gimmick of Compellent I don't think is necessarily with single workload maximum throughputs, it's maximizing throughput relative to total system capacity with automatic tiering to cheaper disk.
I think the irony of this model, though, is that as SSD prices fall, capacities increase and general reliability goes up this whole model kind of falls apart. Why would you even bother tiering to slow rust if you could just use all flash? It greatly decreaes the software complexity, power consumption, etc.
The bigger problem becomes bus connectivity to lots of SSDs. A 24 slot shelf of SSDs seems like its pushing the envelope of SAS bus connectivity.
It looks like a serious degredation of peformance from the perspective of the difference between what the drives should be capable of versus what the bug limits them to, but the GP poster sort has a point in that the drive's performance doesn't seem to be dropping even to the level of a USB3 flash disk let alone a mechanical SATA disk.
Obviously nobody but the actual user of a specific setup would know whether or not it was burdensome, but I would be kind of surprised if it was generally noticable. I see a lot of commercial SANs in use by medium sized enterprises as backing stores for VM host clusters consisting of TBs of data used by SQL, SMB, Exchange that don't exceed 1000 IOPS and 75 MB/sec.
If this represents a real business workload, I would be kind of curious to know what kind of a workload you'd have to present to a stripe set of SSDs to see the effects of this performance bug. The linked article shows some kind of performance graph hitting a low of 100 MB/sec sustained read. A raid 0 stripe would be close to 200 MB/sec sustained read at worst. Maybe you'd notice it, but it seems like a pretty unusual workload that would expose this.
The Middle East has never been at peace and never will. I wish we'd stop meddling and let them solve their own problems their own way and if we don't like it, well tough shit.
Isn't this what we're doing or at least allowing to happen? Finally getting to the point where the Islamists can fight their own version of the 30 Years' War?
Syria is a shredded mess, Lebanon has more factions than LA has street gangs, Iraq is only viable as a state if you close one eye and look at it sideways, Iran's economy is teetering while still trying to maintain some semblance of regional influence in Lebanon, Iraq and now Yemen. Even the Saudis are getting into the game with their air campaign in Yemen and the desire to import a Pakistani mercenary army to fight on the ground.
The way it's going, the Middle East will be as spent and rudderless as it might have been after one of the Roman/Parthian stalemates.
I've noticed a fair number of very attractive short women often end up with short men.
It may be that generally speaking people prefer a mate who is similar to them in size -- perhaps there's even some evolutionary biology explanation where small women prefer a smaller mate because it reduces the risk to her of having a large baby that is difficult to birth. Maybe it's some kind of social psychology, a small woman may believe a large man will be unpleasant to mate with because of his bulk or that somehow big men have big penises and would be painful to have sex with.
But whenever I notice it, I find it strange that if male height is some kind of marker for desirability why a very attractive woman who could otherwise gain a taller mate who would come with the all the social and perhaps even physical advantages of height actively choose mates who are not just closer to them in height but below average in height.
I think static linking makes a lot of sense, but you will get a lot of resistance from people who say that it makes patching harder because some vulnerabilities will now require more patching (eg, SSL) because every application will have their own copy.
I think this is debatable in some ways, because it assumes every security issue affects a shared library and not part of the core executable. It also ignores the applications that merge shared library code or provide a system available function internally (often to avoid weird version mismatches or system incompatibilities). These may or may not even have the vulnerability based on what code was merged.
I think to some degree some VM "appliances" start to approximate a kind of application virtualization. Several greatly strip a distribution of unused kernel and system components down to the bare minimum necessary to run the application.
I'm sure some product does this, but it would be interesting to see a virtualization system that could take an application and generate a bootable VM, merging into the VM only the parts of the operating system actually used by the application and resulting in a lighter weight VM that was still standalone and didn't require a specific host OS.
Secret pay agreements create an imbalance of power between employers and employees because they eliminate pricing transparency and allow for non-rational pay inequity, such as racial, gender or merely office politics reasons.
There's no reason people need to be paid the *same* -- different people bring different skills and experience to the table as well as being hired in different points in time when skills may have been more or less in demand.
Two people may do the same job and make different wages, but they're not the same person, either. With transparency, the onus shifts to *management* to justify why people are paid differently, and management has to be cognizant of pay differences being transparent -- they can't deviate significantly without real reasons.
Do you think there's no scheming/bitterness/morale problems *now* relative to pay? Making it secret is much worse.
A company decided to make everyone's salary open knowledge, posted on the wall for everyone to see.
This would better solve gender pay equity than Pao's no-negotiation strategy. It puts more pressure on management to limit pay decisions to something defensable, prevents employees from pitting against each other for pay and minimizes management's ability to overpay or underpay. Employees know where they stand relative to other employees (and what they may need to do to make more). It motivates better paid employees to show they're worth it and makes it harder for well-paid employees to goldbrick.
The problem with no-negotiation is that for any given hire there are a finite number of employees available to take the job and the best candidate is likely to either be a little better or a little worse than average. Without the ability to negotiate, the better candidates will be less inclined to take the job because it only offers average pay and the below average ones will be more likely to take the job because it pays above what they're worth. You'll end up trending towards below average talent for more than they're worth.
Transparency allows for positioned to be negotiated for and if a given hire has an above average skillset and experience, you can agree to pay them more and won't have to worry about justifying it. The same is true the other way around -- it's justifiable to pay below average, too when you have legitimate reasons of skill or experience.
Pao's strategy is right out of the socialist playbook -- arbitrary price controls, and it destroys the free market's ability to seek efficient pricing. This isn't a political complaint, but an economic one. Most current job markets with "secret" pay agreements now are also bad because they create an imbalance between seller and buyer by eliminating pricing information.
It's also pretty sexist because it attributes a behavioral attribute to gender. I'm pretty sure Carly Fiorina, Meg Whitman, and other Fortune 500 CEOs don't have a negotiating weakness.
The thing is, I think it will be the kind of thing that is declared life by a committee of microbiologists, virologists, chemists and physicists on a split decision.
It will leave plenty of room for the usual cast of religious nutjobs to say it isn't life and it will be the kind of thing that will open the door for endless debate as to whether it really is life.
I think it would take an organism much more recognizable as life and/or intelligent to really be groundbreaking.
Life outside the solar system seems more significant than inside it.
I have a feeling that a find of life inside the solar system will end up being something weird along the lines of a virus or bacteria that chemically might qualify as "life" but is so marginal that it only excites a biochemist.
Plus there's the notion that whatever caused life on Earth might have contributed something to life elsewhere in the solar system.
Life outside the solar system seems more likely to be intelligent (given that we'd have to detect meaningful activity, not electron micrographs or chemical assays you'd pick up on site) and statistically unrelated to life on earth because of the distance.
What exactly is so special about installing solar panels? It sounds to me like pretty conventional electrical and construction work.
Even recreational marine electrical systems can be more complicated, with a mix of solar, wind, grid, generator, battery (12/24/48V) and mixed loads (native, 12v, AC).
Right now? That's been going on for decades. I dated a woman briefly who was trying to get a commercial pilot license and her boyfriend (it was a complicated relationship...) was a pilot for a regional feeder airline and he was making less than I was as a low-level civil servant at the University. And this was circa 1991.
His hours were crazy, too, the kinds of work patterns you'd swear wouldn't be allowed if you asked the random person on the street if pilots should work those kinds of shifts.
The airlines were able to get away with it because they held out the golden carrot of a pilot job on the big planes.
I'm sure this automation idea is being floated by airlines because they want to cut costs. I can't help but believe they see the writing on the wall when oil prices surge again and air travel at the scale we have it now simply becomes economically impractical for the bulk of passengers.
I wonder how much of this objection has nothing to do with the vasty overstated risks but instead is of a commercial nature. Alcoholic beverages are extremely expensive in a lot of places (stadiums, bars, restaurants, events) and sneaking your own in is inconvenient or impossible.
I woner if the real opponents of this aren't people who make money charging $10 for cocktails to captive audiences. How much money do they stand to lose when people start bringing a half-dozen packets to the big game?
How is the drinking control regime threatened when you can't restrict alcohol because of its bulk and liquid nature?
Some idiots will no doubt overconsume it, but they are probably the same idiots that do it now.
Buy it? If they get utility status within a city, I would assume they would string their own backhaul.
I can't see Google tying themselves to Comcast for any purpose, plus there's probably some strategic long-term value to owning their own backhaul network in a city for future services like wireless or cellular.
What do you suppose Google actually uses for backhaul in its municipal fiber? OC-192, 10GBASE-ER? Depending on how many strands they light I would bet the backhaul capacity is probably way less 100G although I'm sure it's engineered so they can light more as usage would dictate.
I'm sure all rollouts probably assume a ton of oversubscription because the greediest average household consumer is going to be what, 4x video streams with random downloads on top of it?
Did you miss the SSD endurance tests where they abused the hell out of SSDs and found them to be way more durable than the skeptical wags like to say they are?
Given normal precautions like backups, they seem good enough to me, at least reasonable brands like Samsung/Intel. I plan to make my next NAS/SAN box totally SSD based, which, by the time I get around to doing it in a year or so will be even more affordable.
Even if the risk of single disk failure is higher than SSD, performance is so overwhelmingly better that it outweighs the assumed marginal increased risk. Getting the equivalent performance out of spinning rust just isn't practical without high powered controllers with huge memory and deep stripe depths.
I'd actually like to see the economics of consumer-grade SSDs in large, commercial-style SANs given the endurance test results. The money charged for SLC flash disks is crazy expensive from SAN vendors. I have the suspicion that the failure rate of decent MLC disks is probably outweighed by their low cost relative to the upfront cost of SLC.

I have the suspicion that the failure rate of decent MLC disks is probably outweighed by their low cost relative to the upfront cost of SLC.
