I would vote you up if I could. There are in fact real technical problems with showing life content in HTML5 videos. And while there are a couple of proposals on how to address this issue, there is so far no consensus among browser makers. I expect things to get better quickly, as all major browsers are rapidly moving away from Flash. But for a small numbers of specific use cases, HTML5 does not quite have an adequate answer.

The bad news is that this will be painful for the smallish number of affected web developers. The good news is that most of the problem cases have been identified and are actively being worked on

Comment Re:then can create a single wifi network? (Score 1) 47

I have tried that many times. And it even almost works. But in the long run, there always are problems. Connections stop letting data go through. Clients fail to roam when they should. Bandwidth drops inexplicably.

It's just not a mode that is well supported by most consumer-level hardware. You are much better off buying hardware that was designed as an access point rather than a router.

Yes, this is exactly how WiFi was designed to work. In big cities, the noise floor is so high that frequently, you need one access point per room or two. So, the ability for a client to roam seamlessly is pretty important.

And generally things worked fine that way, back in the day when you could buy WiFi "access points" instead of WiFi "routers". These days, the router function usually gets into the way, though. For many consumer models, you are supposed to be able to selectively disable routing; but in my experience this never works properly. It might seem to work for a day, but then all of a sudden connections keep dropping and become unresponsive. It's just a mode that isn't tested much. And consumer WiFi devices tend to be poorly tested to begin with. Manufacturers care more about rolling out the next cool thing, rather than debugging and fine-tuning existing hardware.

The solution, of course, is to refrain from buying consumer-grade hardware. Instead, you should get semi-professional hardware. I have had amazingly great luck with Ubiquiti's Unifi series of access points. They are not even more expensive than normal consumer-grade hardware. But they simply just work. Put a couple of their access points across the house, and never worry about poor WiFi performance. You can walk all over the house, and you'll never lose connectivity.

The downside is that you'll need a router to plug all these devices into. And ideally, this router should be POE enabled (although, you could use the included POE injectors).

But if you ever wondered how large office buildings make sure their WiFi works correctly, or why some hotels have working WiFi and others never seem to manage; well, now you know. If you spot Unifi access points in the hallways, chances are that WiFi is going to work correctly.

Both Apple and Ireland claim that the tax rate always applied to everybody and not just to a specific company. Furthermore, Apple claims to be current on all of their Irish taxes and to, in fact, be Ireland's largest tax payer.

The EU claims that none of these statements are true.

It'll be interesting to see which side is closer to the actual truth once the facts slowly become public.

Comment Horribly bad and confusing summary (Score 1) 46

I'll never understand why Slashdot likes to link to poorly written and misleading summaries, when the original blog post is so much more readable and informative. I suggest everybody skip the "Quartz" article and instead read the original blog post. Thankfully, for once it was in fact included in the Slashdot summary, even if it was downplayed:

There is an obvious way to fix this. But it takes a lot of work to change the existing culture, and the transition phase will be painful.

Do what Europe has been doing successfully for decades. Lower the drinking age to 16 years, and raise the driving age to 18 years. Kids will still drink, but the thrill of doing something crazy and/or illegal has long since worn off, by the time they get their drivers licenses and get into college. Also, there is a lot less stigma around drinking. So, calling another adult to give you a ride home is really not a big deal.

I have grown up in this culture (in Germany), and excessive drinking is a lot less of a problem than it is in the US. People still get drunk, don't get me wrong, but hear of far fewer cases of drunk driving and I have a really hard time remembering the last time I heard of anybody going to the hospital with alcohol poisoning.

You'll be even more fucked if the EU ruling stands. According to what the US government has been saying for the last few days, if Apple ends up paying back taxes in Ireland, the IRS will have to credit them for (part of) that amount. So, Apple would pay even less in the US.

That's why the US, Ireland, and Apple all agree, you can't arbitrarily change tax rules and pick and choose what you happen to like. There are international treaties and all of them are interconnected. They probably should be changed. But that has to be a concerted effort for there not to be bad unintended consequences.

Comment Re:HD-Traffic vs. SD-Traffic (Score 4, Interesting) 75

How can T-Mobile differentiate between these, as far as I know the connection to youtube is cryptographically secured.

Even with TLS encrypted HTTPS connections, you can see the domain name of the request. If it says, T-Mobile can rate limit the connection to something much slower than what it usually would give you. And the rate limiting forces YouTube to downgrade the video resolution.

So, it's not T-Mobile that selects the lower video resolution, it's YouTube. All T-Mobile does is provide differential network performance based on service; of course, that sounds suspiciously close to a violation of network neutrality. But that's a question for the FCC to decide.

I suspect the reason why this originally didn't work for YouTube, when T-Mobile first starting rolling out BingeOn is the fact that Google is increasingly using HTTP/2.0 which supports multiple streams in a single connection, and it also is often using QUIC which fundamentally looks very different to a HTTP connection over TCP.
