I wrote a bunch of software for the Amiga back in the day and they all tend to run really well on a emulator on any decent modern PC - actually often better than on the original systems when I designed the game. Sometimes I get nostalgic and play them in an emulator.
The Amiga 500 had 512K of RAM and even expanded to 1MB, it's still less than the cache on a modern PC so you can emulate the entire machine in cached memory - combined with instruction througputs and current clock cycles, a current PC is something like 10,000+ times faster for 32-bit integer operations involving memory.
Why bother? you cannot dismiss the hardware in the middle that GENERATES the audio... if your integrated hardware is poor -- your quality receiver amplifies poor quality audio.
HDMI can output DIGITAL Audio. MS has very good digital audio software mixing and playback algorithms. And many games use a library like FMOD which does software mixing and a DAC output anyhow.
You really only need to worry about a sound card if your PC is outputting ANALOG audio to HIGH QUALITY Amp & Speakers.
They do things like limit the number of miles per day. So you're charged per mile but the maximum number of miles is capped in a single day. This means if you do a road trip where you do a lot of driving in a single day, your insurance won't suddenly go through the roof. This only works if they collect mileage data per day. But they also collect other info like speed and braking which could determine whether or not you're at fault in an accident (and if you're not at fault, could possibly help you?).
There were a number of things I liked about the Automatic app but the Metromile just seemed to work much better (didn't lose trips) and it was free. If you're gonna be tracked while driving, I'd recommend the Metromile device.
And with Sidecar, you actually have to enter where you are going before you request a ride so drivers don't have to take customers that would make them drive somewhere they didn't want to go.
Also, a bit of the "customer roulette" is removed in the ride sharing apps since Drivers can rate their Passengers. With Lyft, if a driver gives you a poor rating, they will never get you as a customer again.
Uber, Lyft, Sidecar etc. all avoid the enormous cost of Taxi Medallions (which are hundreds of thousands of dollars and in some places pushing 7 figures) -- PER CAB !!!!
However, circumventing medallions is not necessarily a bad thing considering the downsides of medallions.
FFMPEG is a program that supports hundreds of Codecs. It's likely they used a H264 or a compatible variant as the actual codec because a) its currently the most commonly used advanced video compression algorithm, b) there is plentiful hardware and software support for encoding / decoding, and c) it has a very good tradeoff for quality, bitrate, and processing horsepower required.
There is no guarantee you will get keyframes using H264 if you are compressing video without detectable screen cuts. Some H264 compliant codecs, like the very commonly used x264 library (used by FFMPEG), do not even need to have dedicated keyframes at all but rather use a technique called Periodic Intra Refresh to encode videos without keyframes. Periodic Intra Refresh provides much better streaming/live capture performance since it lowers both encode and decode latency for transmission and it lessens the incidence and severity of data rate spikes when using variable bit rate compression schemes.
Unfortunately this will hit teenagers the most. Contrary to what the supports of the home cherry pick, those who earn minimum wage have the least amount of experience.
Did you know that in the 1980's you could make minimum wage and pay for rent, food, and your college tuition? In fact, minimum wage in the 1980's was around twice the average college bills for in-state tuitions. (While the article I linked was for Ohio, it holds true for most of the country at the time and certainly in WI where I went to college).
Imagine being able to work a minimum wage job part time through college and come out with a degree and little or no debt. While it sounds ludicrous in today's world, this was the reality of America only 30 years ago.
Ummm... have you tried talking to Siri or Cortana or Google Now lately? Yeah... I'm sure the machines will get my orders right at least 25% of the time.
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.
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.
Although, ideally, you'd just pay for a movie once to own it in the highest resolution available and then you'd be able to watch it in any quality that or less on any device.
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.
Also, the power adapter is a little bulky and would obscure both the outlets next to it on my surge protector power strip. To avoid wasting three outlet, I am using a short 1 foot extension cable.
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.

You can save $$$ on low mileage car insurance if you agree to be monitored by Metromile.
Not quite sure how this is flamebait? Some people would actually like to save money even at the expense of a little privacy.

I bought the Automatic for $99.95. I had a number of issues with it. When I found out about Metromile for free I decided to give that a try as well.
There were a number of things I liked about the Automatic app but the Metromile just seemed to work much better (didn't lose trips) and it was free. If you're gonna be tracked while driving, I'd recommend the Metromile device.

At least the machines will get your order right.

You can already buy a device that does this: Gefen HDMI Detective Plus
Although, ideally, you'd just pay for a movie once to own it in the highest resolution available and then you'd be able to watch it in any quality that or less on any device.
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.

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.
I would mod this up if I had points. I'm a big fan of Spothero. It works great in Chicago.
