I have two major beefs with IPV6. The first is that the end-point 2^48 switch address space wasn't well thought-through. Hey, wouldn't it be great if we didn't have to use NAT and give all of those IOT devices their own IPV6 address? Well... no actually, NAT does a pretty good job of obscuring the internal topology of the end-point network. Just having a statefull firewall and no NAT exposes the internal topology. Not such a good idea.

The second is that all the discovery protocols were left unencrypted and made complex enough to virtually guarantee a plethora of possible exploits. Some have been discovered and fixed, I guarantee there are many more in the wings. IPV4 security is a well known problem with well known solutions. IPV6 security is a different beast entirely.

Other problems including the excessively flexible protocol layering allowing for all sorts of encapsulation tricks (some of which have already been demonstrated), pasting on a 'mandatory' IPSEC without integration with a mandatory secure validation framework (making it worthless w/regards to generic applications being able to assert a packet-level secure connection), assumptions that the address space would be too big to scan (yah right... the hackers didn't get that memo my tcpdump tells me), not making use of MAC-layer features that would have improved local LAN security, if only a little. Also idiotically and arbitrarily blocking off a switch subspace, eating 48 bits for no good reason and trying to disallow routing within that space (which will soon have to be changed considering that number of people who want to have stateful *routers* to break up their sub-48-bit traffic and who have no desire whatsoever to treat those 48 bits as one big switched sub-space).

The list goes on. But now we are saddled with this pile, so we have to deal with it.


Comment Flood defenses? (Score 5, Informative) 121

There is no flood defense possible for most businesses at the tail-end of the pipe. When an attacker pushes a terrabit/s at you and at all the routers in the path leading to you as well as other leafs that terminate at those routers, from 3 million different IP addresses from compromised IOT devices, your internet pipes are dead, no matter how much redundancy you have.

Only the biggest companies out there can handle these kinds of attacks. The backbone providers have some defenses, but it isn't as simple as just blocking a few IPs.

Tivo is in a mad rush to somehow become a distant second place with no direct competitor.

I got DirectTV over a decade ago to feed a DirecTivo. On not being able to replace them as they wore out, one tuner at at time, I bought a newer tiro (Romio[?]) and switched to cable. (When asked why I was cancelling, I told him point blank, "Your DVRs suck." They are at least an entire generation behind in what they offer).

I quickly became underwhelmed by the new Tivo.

Where once it was easy to set a wishlist for all Series Premiers, now you have to search by that for text, which until a few weeks ago, had a staggering failure rate (picked up a couple a season).

With the older Tivos, you could tap the record button to record anything upcoming in the listing, and tap twice to get a season pass. Now, to record a single program is a couple of clicks, and a season pass several.

I'll definitely be looking for other options when this one wears out.

That 3% was all over the lace when I went into their store to activate phones a couple of weeks ago.

I want today that I also initialed it but it may just be that I read things before signing.

And it's not even automatic throttling at that point, but rather lower priority on the available bandwidth: if there's enough bandwidth you still get LTE.

Im also looked at MetroPCs, which was quite clear that their data was lower priority on the network than Tmobile accounts.

So, smokers yes, races no.


In your fallacious example, you attempt to conflate an activity with a state of being. You cannot ban a black person for being black. Likewise, you cannot ban a smoker for being a smoker. However, you can ban the activity of smoking in your venue.

Comment "Wouldn't they be stuck in the traffic as well?" (Score 0) 60

"Wouldn't they be stuck in the traffic as well?"

I believe the theory is that if you practice something, you get better at it. An Uber driver (presumably) practices driving, which means they get better at it, which means that they don't automatically slow down any time they see a huge ball of fire in the sky (try 101 Northbound at 4-5 PM), or other stupid things that less practiced drivers do, meaning they end up not clogging things up, like less practiced drivers tend to do.

The expression "Sunday driver" is actually based on observations.

You just use the scroll-wheel. The scroll bar is always a last resort. I prefer the scroll-wheel myself, but if the system doesn't have a mouse -- that is, one only has the trackpad, then either two-finger scrolling (Apple style) or one-finger-right-side-of-pad scrolling is a pretty good substitute.


Comment Primary problem is the touchpad hardware (Score 1) 183

The real problem is the touchpad hardware. The touchpad device itself may not be able to accurately track three or four fingers, and there isn't a thing the operating system can do to fix it. I've noticed this on chromebooks, in particular when I ported the touchpad driver for the Acer C720. The hardware gets very confused if you put more than two fingers down on the pad horizontally (or you cross them horizontally while you slide your fingers around).

It basically makes using more than two fingers very unreliable. My presumption is that a lot of laptops out there with these pads probably have the same hardware limitations.

This is what makes Sundar Pichai's tweet especially puzzling. When Steve Jobs passed away, Google gave over its home page to a memorial, with a link to a page on Apple's Web site. There wasn't even a discussion on whether this was appropriate; it was simply done, because of course it should be done.

A week later, DMR passes, who was arguably a greater contributor than Jobs, yet no memorial appeared on Google's home page. One of the excuses given was that potential destinations for a memorial link wouldn't be able to handle the traffic. Even after being called on it during a company meeting, Google management remained unswayed.

I thought their handling of the affair was rather ad-hoc and sloppy -- not in line with the company's image at all.

Comment They already know the cause. (Score 4, Interesting) 145

The fact that they can't determine why these phones are going up in smoke is scary. In a way it's understandable; the ones that do end up exploding burn up so there's no system logs or other evidence that could be checked to determine the cause.

The problem is obviously the charging circuit. If it were anything else, they could just put in better batteries, or ship better chargers. The recall happened because the problem is on board the phone itself.

Newer phones still have the problem, so we know it's a design problem, rather than a component sourcing problem (like the counterfeit capacitors problem). In addition, Samsung manufactures their own phones, and their assembly lines operate differently, compared to Chinese assembly lines at Foxconn: it's very easy for them to localize a problem in the manufacturing process, whereas Foxconn goes out of their way to hide it by making bad employees into nameless cogs.

So basically, they have a design problem in the charging circuit, probably in the cell leveling portion of the charger, in the same way that the "Hoverboard" clones that keep starting on fire have a known bad charging circuit that overcharges some lithium cells in the larger battery, while other lithium cells get too little charge, on the charging circuit keeps drawing amps for all of the cells.

Then when the overcharged cells are discharged, they pretty much "Flame On!", and someone does a fair imitation of The Human Torch(tm).

This stuff isn't rocket science, it's basically third year in a U.S. community college EE and analog circuit design.
