Comment Re:The always-present question for UDP (Score 3, Interesting) 97

QUIC uses an equivalent of SYN cookies to prevent some kinds of DoS. It also uses packet reception proofs to prevent some ACK spoofing attacks that TCP is vulnerable to. Overall it looks even better than TCP.

As for encryption, Google gives two reasons. They intend to run HTTP over QUIC and Google services are encrypted by default; it's more efficient for QUIC itself to implement encryption than to layer HTTP over TLS over QUIC. The other reason is that middleboxes do so much packet mangling that encryption is the only way to avoid/detect it.

Comment Real multitasking (Score 3, Informative) 152

I used to have an N900 running Maemo with "true multitasking". A poorly-written app in the background (like Firefox with the "full Web experience" of Flash) would run down the battery in two hours. But at least I could use top to find the problem and kill -9 it.

Now I use Android where apps are specifically written to be aware of my battery.

But since most ISPs are either unlimited or have such punitive overage charges that customers will never pay them, greater demand for bandwidth generally does not translate into more revenue for ISPs. Even the lowest tier 5 Mbps plan is sufficient to watch Netflix.

Comment The real reason is cost (Score 1) 128

In low-cost systems the CPU and GPU are combined on a single chip with a single (slow) memory controller. Given that constraint, AMD is trying to at least wring as much efficiency as they can from that single cheap chip. I salute them for trying to give customers more for their money, but let's admit that this hUMA thing is not about breaking performance records.
