QUIC: Google's New Secure UDP-Based Protocol

Wesley Felter Re:That's a terrible idea (97 comments)

QUIC has congestion control. (I suppose your brain would explode if you saw uTP, which runs over UDP yet is even less aggressive than TCP.)

QUIC: Google's New Secure UDP-Based Protocol

Wesley Felter Re:Not necessarily the right place (97 comments)

I think Google intends to put it in the kernel once they have finished actually designing and standardizing it. Since it would take 10-15 years to get QUIC into the Windows kernel, they're putting it in Chrome as a stopgap.

QUIC: Google's New Secure UDP-Based Protocol

Wesley Felter Re:The always-present question for UDP (97 comments)

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.

He's including free speech in civil rights. He supports free speech for everyone except fanboys and trolls.

Rough Roving: Curiosity's Wheels Show Damage

Wesley Felter Typical auto industry (78 comments)

The rover loses 30% of its value as soon as you drive it off the lot. And if NASA tries to trade it in I bet a lot of "damage" will be discovered to drive down the price.

Jolla Announces First Meego Phone Available By End 2013

Wesley Felter Real multitasking (152 comments)

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.

How Netflix Eats the Internet

Wesley Felter Re:Is Netflix (303 comments)

That was kinda my point; people with a 15 GB cap will not sign up for Netflix at all. They won't sign up for Netflix, blow their cap, and pay $100/month in overages. So Netflix does not cause ISPs to earn more money.

How Netflix Eats the Internet

Wesley Felter BitTorrent traffic has dropped dramatically (303 comments)

A lot of BitTorrent traffic shifted to cyberlockers like MegaUpload a few years ago; I don't know if it has come back since then.

How Netflix Eats the Internet

Wesley Felter Re:Is Netflix (303 comments)

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.

AMD Details Next-Gen Kaveri APU's Shared Memory Architecture

Wesley Felter The real reason is cost (128 comments)

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.

AMD Details Next-Gen Kaveri APU's Shared Memory Architecture

Wesley Felter Re:The PS4 (128 comments)

One of the problems with the PS3 is that it didn't have shared memory. Maybe you're thinking of the 360.

Wayland 1.1 Released — Now With Raspberry Pi Support

Wesley Felter Re:Dead on arrival? (197 comments)

Yeah, I'm thinking 30" monitor + keyboard + mouse, apps that aren't forced full screen, a real file system instead of crippled sandboxes, etc. If tablets can deliver that, more power to 'em, but I doubt it.

Wayland 1.1 Released — Now With Raspberry Pi Support

Wesley Felter Re:Dead on arrival? (197 comments)

Even years from now there will still be a few people who do actual work, and they won't be using tablets to do it. They'll be using computers and they'll need an OS which is optimized for productivity, not gaming, watching movies, tweeting, or shopping at Amazon. Few as they are, these people are willing to pay real money for a computer, like $2,000. Perhaps that is what GNOME and KDE should focus on, considering that Microsoft, Apple, Google, and Canonical don't care.

Jolla Ports Wayland To Android GPU Drivers

Wesley Felter It's even simpler than that (90 comments)

The reported reasoning for making Wayland support Android GPU drivers was difficulty in ODM vendors not wishing to offer driver support for platforms aside from Android.

ODMs don't know how to write software, so you're better off not asking them to; the result would just be garbage anyway. All the GPU drivers are actually written by the GPU IP vendors (Qualcomm, Imagination, ARM, etc.) and they only provide Android drivers. You could try to pay them to write KMS/DRM drivers, but they'd probably quote you a price in the millions which minority platform wannabes like Jolla could not afford anyway.

Not really; they're just slow enough that power isn't a problem.

Cliff Bleszinski: Vote With Your Dollars

Wesley Felter Re:I dont think user hate DLC (369 comments)

Back in the pre-DLC days they would have developed the ending but cut back on the middle of the game. I'm not aware of any games where critical mechanics are DLC; wouldn't that make the base game unplayable?
