How about a Microsoft touch mouse? They are much cheaper and have no wheel. You can program them as three buttons.

I can tell 1080p from 4k on a 130cm screen from 3m away, with 4k media. I can tell when 1080p media is upscaled on the same screen too. I can also tell 8k apart from 4k under the same conditions, which is actually easier since 8k doubles the frame rate too.

It's not just resolution. 4k has better colour. It's more noticeable on outdoor scenes with a lot of natural tones and dynamic range. Skin looks a lot more realistic too... It's actually kind of a problem because actors that look fine in 1080p look like they are wearing make up in 4k (which of course they are).

The automatic breaking systems only work at low speed (typically max 30 mph), and are very conservative. Unless you are doing less then about 10 mph they won't even stop you hitting the object, just lessen the impact. They use antilock braking and if the car skids or the driver reacts by turning the wheel, braking or accelerating they instantly disengage.

There are probably a few real edge cases were they might make things slightly worse, but it's hard to imagine a situation where they could cause someone to actually die.

The business model is well established and works. Captive audience, unable to compare prices, boredom and left over holiday money to burn. Exactly the same one that worked so well at airports, until recently. On holiday consumers tend to be in "high spend" mode too, splashing out on stuff they wouldn't buy at home.

And the fact that you couldn't compare prices at 11,000m up. I forgot that.

They relied on a mixture of boredom and left over holiday money.

I get my packages delivered to my place of work. There is always someone available to sign for them, and being a business the couriers actually bother to knock because they know someone will answer quickly. They usually have multiple packages anyway.

Every place I have worked does this for staff.

Windows Defender isn't a traditional AV app, and the head-to-head detection tests don't do it justice. Rather than relying on having signatures for every virus going or heavy weight (slow) heuristics like most AV software does it just relies on blocking infections via the most common infection vectors, and spotting specific tricks used to hide malware. The result is that it is very light weight and doesn't slow the computer down, but still blocks most of the crap that would otherwise infect the system.

Malware detection rates are misleading. Great, your software can detect the infection after it's already happened and probably can't remove it now. Focus on prevention and the most common threats, combined with a secure browser and some common sense. Traditional AV tries to stop the user being a moron, which is a recipe for failure.

Try Microsoft Security Essentials. It's very light weight and doesn't slow the machine down. It isn't the perfect AV software either, but it does detect a fair bit of crap and costs nothing.

Also download Clamwin and run a scan now and again. It can run portable, no need to install it.

They help but don't make your browser completely immune to exploits. It still has to parse HTML, interact with the network, decode and render images etc.

0.0015 ampere hours = 1.5mAh. A smallish phone battery such as the one found in an iPhone 6 is 1800mAh, with previous generations being about 1500mAh, so it's about 1000x less than that. A high end phone is typically around 3000mAh.

Laptops tend to be in the 5,000mAh range and upwards.

Brawn, Prowl, Ratchet and Ironhide were all killed in the first five minutes with barely a fight, and for no other reason than to make way for the new toys.

One of the most fundamental parts of democracy is that no-one has too much power, and certainly never absolute power. There always has to be a balance.

Seems like using the manual override once in a blue moon to ventilate and stay warm would be less effort than using it every day for regular climate control. That's why most people have a programmable central heating system in western Europe, with override buttons for the rare occasions they are needed.

If you really know what you are doing then setting up your own server is the best option, because the security services prefer to target large providers where they can compromise millions of accounts in bulk instead of doing after individual systems with varied security.

If you are not capable of setting up something really secure yourself you are better off trusting someone who can.
