I am concerned about the lubrication and circuit boards (electrolytic caps, mostly) associated with hard disks over long term storage. I have found a high failure rate on my own old hard drives - old MFM drives were kind of crappily engineered, however, so the fact that an ST-251 drive from 1990 doesn't work today shouldn't necessarily be indicative of the lifespan of say, a WD Black 1TB manufactured in 2010.
In my world, we rely on practical tests of functionality *with the actual users* rather than theoretical measures of effectiveness. It seems the CDC agrees with me on this one.
As to one of your other points:
"The bottom line is that a single act of intercourse between a young couple has on average a one in 20 chance of pregnancy – this assumes the opportunity presented itself on a random day, as these things tend do when you are young."
So the answer is based on how often you fuck. The CDC numbers do not map precisely to data of this sort, however.
Last point: "measuring the effectiveness of encouraging people not to fuck" sounds like the craptastic questionnaire-based research I saw at (not to pick on them) the Lehigh psych department in the early 2000s. People lie, and they can't simulate the paths not taken effectively. There would literally be no way to know if someone decided to not have sexual intercourse based on an abstinence campaign.
Besides, my kind of abstinence campaign would be "Blowjobs for Everyone" or "Real lovers wank each other".
Just wait till the first provider goes dark, and you lose all your data.
I'll still be sitting here with BACKUP TAPES!!!
Now get off my lawn.
Not the one you dream of. The CDC's numbers are correct.
Actual effectiveness ratios for birth control:
Condoms are about as effective as the withdrawal method, sponges, or the rhythm method. 20% or so failure rates.
Spermicides are worse (!) (28%)
9% annual failure on the pill.
The only truly effective contraception methods are *just* the methods they won't allow young kids to get. I had to get a signoff from my wife at age 29 for a vasectomy. I was told they wouldn't do it if i were single or if I had been married with no children. Reason: ex post facto lawsuits by women aggrieved by the urologist denying them children within their marriage. Similarly, just try walking in and asking for your tubes tied at 16 or an IUD implant.
The bottom line is that the "conservatives" advocating abstinence training are actually right. The only actual way to reduce teen pregnancy is to encourage them to stop fucking so much. The birth control available to them _does not work_. They should all just screw bareback from what I can see.
When they talk about the "user experience" they mean someone who is buying ads, not the person who is posting "Look what Hillary Trump said last night" every day. Think in terms of Facebook's customers.
Knowing who is talking to whom is an important part of Facebook's marketing. Look at how Facebook targets and consider item #19 in that article. It's not just about who you are, it's about who you know. Whether you think this is a good idea for Facebook or not, it is what they do.
User A and user B are friends in real life, use Whatsapp, and have Facebook accounts -- but they're not "friends" on Facebook (maybe they only use Facebook for work, or something like that). (Or maybe they don't have Facebook accounts, but Facebook has profiles on them gathered by "like" buttons, and has some way to deliver ads to at least one of them.) They communicate with each other using Whatsapp. This lets Facebook connect the two profiles, even though within Facebook alone, they are unconnected. The result: Now user A can see shopping ads for user B's upcoming birthday.
The advertiser has a good products experience.
Ad hominem is the last refuge of the defeated.
Even Windows has BSD in the network stack.
It's interesting to note that you, and the rest of the people posting about how much they care about warming and people that they don't know, or even future generations, still bothered to reply to this message instead of junking their computers, selling their houses and cars and living in a tent in the woods with appropriate technology. Or even killing yourselves - after all, as long as you exist, you're fueling resource extraction, pollution and warming.
So I guess you all don't care as much as you think you do.
Why the hell should anyone care about abstract "people"? Humanity isn't wired that way, we care about those we know, not about the distant future and people we don't know. No one really does, anyway. It's always some self-interest, really, when you dig down into people's true motives. Perhaps to appear better than others by some arbitrary standard.
Anyway, your comment comes off as naive, immature raving. Yes, it's true we don't care, collectively. But expecting us to is idiotic.
There are lots of people angry at that person(s). I think if they were identified, vigilante justice would be likely.
Where were you when the Manning dump killed dozens of agents?
Or just take the easy way out and blame the company?
My laptop died while I was on travel. I want to select my next expensive device carefully, so I need a disposable computer, something I can hand off to a computerless person in a few months. I went last night to Micro Center and bought a $219 Acer laptop, a $55 250GB SSD and a $35 8GB stick of DDR3L RAM. And a screwdriver, spudger and static strap.
2 hours later, I was able to shove an Ubuntu 16.04 live DVD into the drive of this thing and start computing on the hotel network. The removed 500GB hard drive preloaded with Windows 10 (yuck) and the OEM 4GB stick of RAM sat alongside it.
I was able to completely avoid Microsoft's preloaded pile of shit and other than throwing a couple of switches in the BIOS, it was fairly painless...for me*. And I got a pretty responsive system for my effort. Compare and contrast to the cellphone situation.
I roll with an iPhone for this reason. My last Android device (HTC Desire Z) was my last Android device, ever.
*this system being such a POS that I had to remove the entire motherboard, blower fan and WLAN card to change out one SODIMM of RAM. The plastic bottom even has a nifty RAM chip pressed into the (nonremovable) solid bottom of the case, as if it were some kind of access door.
