Comment Re:now I never looked into it (Score 1) 420

The difficulty is not the ability to do it, it is that the energy requirements make it economically uncompetitive. Boiling that much water and then collecting the condensation generally takes a LOT of energy which is quite expensive in most cases.

It's worth noting that you can use the energy released by condensation to preheat water before it's boiled as well as use the temperature difference between just condensed water to preheat intake water. If you have high enough efficiency in your heat exchangers, you can significantly lower your energy requirements to boil water.

Comment Re:OPENSSL_NO_HEARTBEATS (Score 1) 144

You're referring to the exploit-mitigation-mitigation in OpenSSL, which indeed couldn't be disabled, as per tedu@openbsd, but OPENSSL_NO_HEARTBEATS was a separate option that noone has volunteered to claim of not working.

OPENSSL_NO_HEARTBEATS has since been made the default and only option in LibreSSL, and the heartbeats were removed.

But even with OPENSSL_NO_HEARTBEATS, if you are using a faulty allocator that lets you read data that has already been freed, you will still may be able to come up with other exploits (which are highly likely to exist in complicated software) that will let you read that data that you thought was "gone".

Except it doesn't work that way at all. Analysis of political contributions show that the wealthy donate disproportionately more. A mere 0.01% of the population (27,000 donors out of a population of 304M) are responsible for about a quarter of political donations (24.3%).

In the video game industry, we see a similarity with profits on "free to play" games where the vast majority of profits comes from the top few percent of "whales".

The truth is, most people won't part with large sums of money unless they have a lot of disposable income (or poor judgment). In politics, the "whales" are typically the richest of the rich - the top fraction of a percent.

Yes it did. You were not vulnerable if you have built OpenSSL with the feature disabled.

Except that OpenSSL actually didn't run with the "feature disabled" (internal freelist-based memory allocator) due to uninitialized memory bugs in OpenSSL that required newly allocated blocks of certain types to have memory set in them from previously freed blocks. See details here.

Comment Price for Bitrate / Resolution? (Score 1) 347

I'd be ok with a price for bitrate or quality.

You can have a much smaller / lower quality file (SD'ish) for a smartphone than for a 60" TV (where you want at least 720 and probably 1080).

They already charge a higher rate for HD movies than SD movies on a number of streaming rental sites so it's not even a "future" rental model.

Comment Re:We do not need solid state to replace platter d (Score 1) 256

In fact, I guarantee if someone made a hard drive with a controller with an mSATA slot for adding a SSD and offered the controller to be setup as pass-through (act as two drives) or caching (SSD keeps a cache of platter), it would sell like crazy.

This already exists. It's called Intel Smart Response Technology and it's been available on motherboards since it was release three years ago in 2011. It works with both mSATA and standard SATA attached drives.

Most people just haven't paid the extra $100-200 to buy an SSD to cache their HD not to mention the technical know-how required to install the drive and setup the BIOS and software correctly.

What we need is systems that are sold with this already built in so users don't have to do it manually. But that adds $100-200 cost to the system and many shoppers look at the price tag first when they're buying a new computer :-(

A fast hard drive can do several hundred or with short stroking on a high RPM drive maybe even a thousand random IOPS (input/output operations per second).

A fast SSD can do 90,000+ random IOPS - or several hundred thousand for direct native PCIe drives that don't have to go through a SATA layer.

For what SSD's do well which is randomly accessing data, they aren't 5 times faster than HD's, they are 100 to 1,000 times faster at RANDOM ACCESS for a SATA connected SSD.

There is a single board Fusion IO card that can do 9 MILLION IOPS which is roughly 10,000 times faster than the fastest hard drives.

One other silly note... I can't find an "off" button or a menu item to turn it off other than unplugging the device. And plugging back in turns it back on. It has a 16W power brick so there might be some continual background power drain if this thing is plugged in. Also, for some reason, the AC adapter made sparks at the plug both times I tried plugging it in. I was a little scared that I might have burnt it out but it seems to work fine.

Also, there is a USB Port. I've got a keyboard hooked up to it right now. However, not all the apps support input with the keyboard and some are clunky. I was hoping to avoid using the remote / controller for passwords and usernames during setup. It worked for a number of things. However, not all apps support the tab key to switch between fields or the enter key (it acts like the select button rather than a completions). The Amazon Video PIN entry also doesn't recognize numbers on the keyboard so you have to use the arrow keys and the enter/return key for select.

I'm hoping that software updates bring a little more polish to using the keyboard but it's not terrible if you consider it to be sort of a public "beta" until a couple software updates occur.

There is support for Plex. I have the Amazon Fire TV and I bought the Plex App for it. It's $0.99 (or 99 Coins) on sale from $4.99 for an introductory period. This works with your PC Plex server or a Drobo or Synology box running Plex server apps.
