Empirically, the "Turbo OC" setting in raspi-config roughly doubles the effective speed of the device. It only bumps the CPU clock from 700Mhz to 1Ghz, but it also increases the memory and GPU clock which has a dramatic improvement on performance. If your Pi becomes crashy in that setting, try scaling back the GPU (Core) clock speed first. The CPU and Memory seem to overclock better than the GPU.
Like I said, the Pi behaves a lot like a late 90s desktop, back when overclocking was worth the effort.
Are you using USB Wifi? USB is notoriously CPU hungry and Wifi USB is the worst.
As for the videos, the playback depends. If they are encoded in a format that you can offload to the GPU, then the Pi will be great. I've played plenty of 1080p video on the Pi over the network using the built-in ethernet using omxplayer. The one big caveat is that it only supports a few codecs, and if you try to play a video encoded differently it will go to the CPU and be unwatchable (less than 1 frame per second). It does support the most popular codecs at least (DivX and H.264).
I'm not sure why you're having so much trouble with X. Once it is started I usually get along just fine, although you do have to be careful not to blow the memory budget. If you start to swap the thing will become horrible. You have to use the machine with the same mindset you would have used with a 15 year old Pentium III machine. Don't ask it to do too much at once and be mindful of your memory use. Keeping to the commandline is also a big help.
Seriously though, look at the built-in overclocking options. They make a huge difference, and they don't even void the warranty unless you go whole hog and start editing the boot.conf file by hand and set crazy voltages. It's just like the old Pentium days where overclocking could dramatically improve a machine instead of being some incremental dick measuring contest like it is today.
What are you trying to do on the Pi? I have an original Raspberry Pi (the 512MB model) and while it's not winning any speed contests it is certainly not unusably slow. I even run Chromium on it, most pages take a few seconds to load but work alright after that. I don't try to open lots of tabs though, the Pi is too memory constrained. Mathematica (which comes bundled with later versions of Raspbian) takes forever to start up, but once it is going it does alright.
I'm even making it drive a 1080p display. I did go and use the raspi-config script to overclock it. It's not totally necessary, but it makes a surprisingly large difference. Upping the memory clock is a huge win in particular. At the "Max OC" setting I was able to keep Quake 3's framerate up in the mid-30s or so.
That way you'll never know how much your trip will cost until you're literally at the gate. Airlines could even play with the price per kilo numbers to make themselves look better on Travelocity or whatever while still being expensive (see also: baggage fees). It also makes reimbursements for business travelers a hassle since the quoted priced on the ticket won't be the final price of the flight. Plus you get the fun of getting the kids to sit still on the scale when boarding, and also the need for the extra delay at the gate so the scale can properly register, and to make sure the guy behind you doesn't have his foot on the scale by accident...
Air travel sucks enough already guys. Please don't push so hard to make it worse. It's not like you're going to save money, even if you are thin. This would purely be a surcharge that every airline would implement, just like baggage fees.
Because it would be an enormous headache. I don't know if you've flown recently, but most people don't go to the ticket counter to buy their tickets anymore. They buy tickets online, and if this policy was in place you would have to make the passenger input their weight and their luggage weight into the system when they buy the ticket, potentially months in advance. Then you need to verify their weight when they get to the airport, even though the only people who go to the counter currently are people who are checking bags or have some sort of emergency and need to spend half an hour going through the ticket buying process and make everybody behind them in line hate them.
There are already policies that make extremely fat people buy two seats which helps catch outliers.
This doesn't make any sense. Alacarte has not seriously been on the table ever, certainly not back with the explosion of reality programming. If you wanted to blame the writers strike on for this it may have made some sense, but saying that all of the channels ruined themselves because people briefly talking about something that wasn't going to happen is just crazy talk.
Here is a thought exercise. What if every channel was like Netflix? If you thought they were making good content you would simply subscribe. Netflix has shown that you can make good original programming on a relatively modest monthly price, and they're paying for a whole lot of licenses on top of that original programming. Imagine if there was a Sci-Fi service that made only Sci-Fi series and you could subscribe. Imagine a food/cooking service. Or a history service. Or even paid 24 hour news. Would you still spend $100 a month on traditional cable with hundreds of channels stuffed full of worthless reality programming? This is what disruptive technology looks like.
The cost is the elephant in the room. Cable has gotten very expensive and the alternatives are so much cheaper. Plus far too many cable channels have dropped their interesting programming for cheap reality programming. How many historical documentaries does the History Channel show now? How much Sci-Fi can you find on SyFy? Animal planet now advertises how "human" they are. How many cooking channels do we really need? The worst part is some of the best new shows are coming out on streaming services like Netflix. The industry still has not realized that their shortsighted greed has doomed them in the long run.
The OpenBSD guys don't care about FIPS, but if someone else does they're more than welcome to take the LibreSSL code and run it through the FIPS process. The OpenBSD team has already said that they think FIPS does more harm than good, because it locks you into exactly one version of the library which makes it difficult to apply fixes without breaking the certification. People want FIPS certification to mean "this has been proven safe", but that's not true and is impossible for non-trivial projects.
Wow, that was the original concept? A one-person per server trophy? What a colossally stupid idea, it's no wonder they ditched it. That one guy is going to get the stupid thing and then unsub. Or retire the character and play something else. At the very least he'll never step in a PvP area again. I can see why they never bothered to implement it.
I'm frankly amazed that they have the check to charge for an expansion on a game that has a monthly subscription fee. It certainly does not take anywhere near $15/person to keep the servers running. Probably closer to a few pennies per person for server costs, a couple of bucks for overhead (secretaries, rent, CEO private jet, etc...), and the rest goes into someone's pocket. By all rights there should be buckets of "free" new content raining down in WoW constantly. They pull in the development budget for a full AAA game every month, and somehow can't manage to develop one new zone and one new player class with that? Where the hell is all of that money going?
Even better: Get a network postscript color laser printer.
Not only will it last forever, but you will be able to use the generic drivers that come with your OS to print on it. No more 200MB driver downloads only to find out that they've dropped support for your OS or don't work on 64 bit systems or whatever. The network postscript color laser is the last printer you'll ever need to buy, and they can be found in the $200 range easily these days.
I have to admit, I expected him to have a full mountain man beard after reading the article. I wonder how long he can maintain this lifestyle before giving up shaving and grooming as too much of a hassle?
One of the design goals of IPv6 was to simplfy the routing logic so we could make faster and cheaper hardware. That's why there is no more IP fragmentation for example. Making the fields variable size defeats that. It's much easier to build hardware for fixed field sizes.
Plus you can't project exponential growth out to infinity. It is inevitable that some factor will come to limit the growth. It has been really incredible how long transistors have maintained their growth, but even that seems to be coming to an end.
Also, we're probably not going to have a 64->128 bit transition. Not without a fundamental change in the way we do computing.
Yeah, HP could give back both of its class As (minus a few/16s for their use) and buy us...a scant few more months before we're in the same situation again. The real solution is to finally get off our asses and switch to IPv6.
They did it because that's how the company that makes the cables describes their test environment. They claim "clear unmistakeable" improvements in the audio quality in the setup Ars used, but only if you plug the cable in in the correct direction (denoted by an arrow on the connectors).
In fact the company claims that they determine which way to face the arrow by plugging the cable in and listening in both directions and choosing the best.
Do you want the seats front facing or rear facing? 10-30lb or 20-50lb? Even then you're going to have to adjust it for your kid, and figure out what sort of bizarre adjustment scheme this particular seat uses. On some seats you have to take them apart to adjust past certain points. Uh oh, the kid always wants to sit behind the driver and the seat is installed on the passenger side.
Who is going to install and remove the seats every time someone calls for one? Are they going to have liability insurance in case they accidentally install a seat improperly and a kid is injured or dies?
And then the parents have to go back and make sure the seat is clean once they're done with the car. Kids are amazing at finding ways of making messes when you least expect it.
I think "have young kids" is one of the ares where the "car as a service" concept does not work. Not unless you drive only very rarely with the kids.
People are sick and tired of car payments and insurance payments.
A subscription service has to pay for these too. They're just hidden from you. Plus there is the additional overhead from the subscription service company. Total cost per mile is roughly the same, the savings come from parking costs and not having to deal with age related problems on the cars because you wear them out with pure mileage before they get old.
You don't have the upfront cost of owning the car, but you end up paying more per mile than people who own cars. There's a tipping point where car-as-a-service don't make sense anymore and a lot of Americans are well past that point. In fact most people who live in the suburbs and anybody rural are past that point. If you don't have ready access to good mass transit then you probably need to own a car. If you do live in a city, then you have to weigh the car-as-a-service option against just using mass transit and taxies, and traditional car rental for those rare occasions where you need to travel a good distance from the city.
Of course EVs in their current form are almost totally unsuited for a subscription model, since their usage model depends on being parked in places with charging support for a relatively long time and only being used on short to medium trips. They're amazing as commuter cars, but not a good idea for a Taxi. Supercharging is hard on the car and should be used sparingly.
Or you know, having to install the kid car seats every time you want to go somewhere would get old fast, especially if it's a different car every time and you have to figure out where the manufacturer hid the bars this time. Or if the car doesn't have the bars and you have to use the seatbelt method. Or the bars are there but spaced differently so you have to adjust the annoyingly difficult to adjust sliders on the seat to make it fit properly.

Nah, the spying stuff is on the Z170 chipset, hidden away in the Intel Management Engine. Too bad Intel killed off third party chipsets awhile back.

While that's true, the number of /48 subnets is still almost unimaginably huge. There is effectively no chance of ever running out of IPv6 addresses.
