I'm still supposed to get dilated yearly so they can check inside, a detached retina is apparently a very real possibility since my eye is so "long". They dilate me because otherwise it's like trying to look into a room thru a peephole - their words not mine.

I'm no eyexpert..
Get dilated, what does that mean? Do they alter the way your eye dilates, like changing its settings?

They put drops (don't know what of) into your eyes, causing the pupils to stay dilated for a little while. Gives the doc easy visual access into your eyeballs.

A smart watch is a smart phone with less functionality that you have to wear around your wrist. I don't understand the appeal at all. Everything it does a smart phone does better, only a smart phone is not strapped to one of your body parts.

I have a Pebble, and it is very handy to be able to discreetly view texts and see caller ID info for incoming calls. Plus it shows me the time (since it still a watch) -- and far better than a regular watch, as it shows me time, date, three week calendar and some other details all at the same time. All of this is great because my phone is in my backpack or pocket the whole time, since I don't like to carry the phone around in my hand.

I have a Pebble watch. It looks cheap, but is pretty cool/handy. The interface tends to be very simple. It can control the music on my phone (without having to look at the watch), allow me to discreetly view texts, and see caller ID info for incoming calls. Those are my favorite features, aside from, you know, indicating the time.

Yes you can hit a button on your wrist easier.

But when dealing with a smart watch you aren't hitting a button. you need to tap a screen 3-4 times in the correct place while running to adjust one feature.

I have a Pebble (which my son says looks like a cheap piece of plastic, and he is right); it can control the music on my phone. Once the watch is in music mode it stays there, so the three buttons let me directly pause or skip back/ahead without looking at the watch.

Being able to discreetly view texts is my favorite feature, thus far. Seeing caller ID info for incoming calls might be my second favorite feature.

A French bank was found by USA to violate its (yes, USA's) policy on the embargo of Iran --- well, that bank was from France, and all its business dealings with Iran was done OUTSIDE the United States, --- and yet, US dare to fine that French bank hundreds of millions of dollars !

What the fuck is going on, people ?

How can the government of country A fine a company from country B any money when that company's dealing has NOTHING to do with country A in the first place ???

Simple, if your business wants to do business in the U.S.A., you'll need to mind the rules. That bank knew the rules and actively falsified documents to make it appear that it was abiding by those rules. They got caught and severely smacked. The fact that they are willing to pay that ginormous fine means they want to make amends with Uncle Sam and *continue* to do business in the U.S.A.

So they claim the SSD writes data to a blank location on the drive temporarily, then erases the original intended location and later moves it back to that location to be contiguous? What's so damn special about that location? Just leave it in the blank location. They claim that causes fragmentation, which has no impact on the performance of an SSD in any way.

This is a useless invention from people who don't know how SSDs work.

You are correct. SSDs don't have a fixed LBA-to-physical arrangement, so host rewrites of an LBA will normally go to a new (erased) NAND location, with the drive updating its internal LBA map automatically (I.e. no need for TRIM of that LBA).

GP is correct about read disturb. NAND vendors will specify specific policy for a given part, but it is typically N reads to a particular area (i.e. one block, which is 256 or 512 or 1024 pages) then requires erasing that area. So even if page 7 in a block is never read, but page 100 is read a lot, the drive will have to rewrite that whole block eventually.

(I work for a NAND controller vendor.)

Not even close to practical. The magnetic disk manufacturers implemented wear leveling back when the drives were in the 200MB-range. Before that disks wore out even quicker than flash disks and I didn't even use swap-files then.
There is a huge difference between unlimited number of writes and undefined number of writes.
In critical applications, a bad number is better than an undefined one. At least you can calculate a life-time and design after that.

No, sir. HDDs (at least up until I stopped writing FW for them in 1999) did not have any wear leveling algorithms. In other words, the translation of LBA to physical location on the media (sometimes called Physical Block Address or PBA) is fixed, other than for defective sectors which have been remapped. So if an O.S. wrote to a specific LBA or range of LBAs repeatedly (think paging/swap file or hibernate file), those PBAs would be written to more frequently (or at least at a different rate) than other PBAs across the drive.

especially once USB gets its shit together and provides enough power to run HDDs without an extra power supply.

It already does... for 2.5" drives.

No it doesn't. At least not spinning rust - those things easily require 2+A to start up. On USB alone, that would prevent them from even starting, nevermind running.

I've been using external USB-powered 2.5" HDDs for years, connecting to laptops, desktops and USB hubs. Works just fine in all situations, which is why companies such as WD are still selling these things like hotcakes.

Let's just ban cars. And scissors. How many people died from choking last year? Surely there's some way to prevent those.

And if they don't ban cars, they should at least ban alcohol, because that would save thousands of auto fatalities per year.
And guns, too....lots of lives to be saved there.
And mosquitos, those little malaria-carrying bastards.

These busy bodies are just thinking too small.
