Comment Obvious problem.... (Score 4, Interesting) 278

Hmm. Seems to me their biggest problem is that they allowed clients with a known bug to become supernodes; if 50% of the network had upgraded, they should only have been creating supernodes from the upgraded clients.

And in hindsight (I don't know that they should be blamed for not considering this before), the number of supernodes should probably be ~100-150% more than needed to service expected load. That way, if a third of them die, they _still_ have more than needed to handle the expected load. (And thus, hopefully, more than needed to handle the excessive load without causing them to shut down).

I realize that the compressing process isn't that hard, but you aren't going to build a car that can run on both gasoline *and* CNG. If for no other reason than because the CNG tank is pressurized while the gasoline tank isn't. It's probably not as bad for mixing as ethanol (at least before they upgraded the gaskets, etc), but it probably still requires some rebuilding. I've never seen a car that said "feed me CNG, petrol, or diesel", so I suspect you are oversimplifying it a bit.

Maybe you haven't, but I have. Well, LPG, but I'm not aware of any reason it wouldn't work with CNG. I remember the propane tank in the back of my dad's truck when I was younger, and the knob under the dash to switch from gasoline to LPG....

Comment Re:How does centralized login solve keylogging? (Score 2, Insightful) 127

And this solves the keylogger problem how?

It doesn't. You still have to authenticate at some point; at most, it reduces the opportunities for a keylogger to catch the password (if you only have to type it in every couple of weeks).

In exchange, it provides phishers with a dream environment. The only way to be certain you're actually connected to your authentication provider is to use SSL and make sure that you see the lock -- and if your security depends on Joe Random User doing that, you've already lost.

Perhaps that's why he specified 'very slow' adsl? At my previous house, Speakeasy and Verizon could provide decent speeds (3.0/768), but there were several providers which only provided ~768K/128K ADSL.

At my current house, I have the option of AT&T, or... well, nothing, really. I guess I could get 3G service, but that's not exactly a competitor to DSL, based on my experiences at my father-in-laws.

Mind you, I'm only ~1/2 mile out from Clear's 4G service area, so I *might* be able to get decent speeds out of that. One more utter screwup from AT&T and I might find out.

What really ticks me off is that I can stand in my daughter's bedroom and *see* the town where Verizon piloted FIOS years ago. But they won't compete with AT&T and offer it here.

Speed, in and of itself, is dangerous. There are conditions where "60m/h" is a generally safe speed. There are conditions were "20m/h" is generally a safe speed. But no matter how you look at that, the higher speed is "more dangerous" in a given circumstance than the lower speed.

No. It isn't.

If I'm on a road with lots of traffic, and everyone else is traveling at the 65MPH speed limit, it is *far* more dangerous for me to drive 20MPH than to drive 65MPH. It's also more dangerous for me to drive 40MPH than 65MPH.

Speed *differential* is dangerous, not speed itself.

Comment Re:changing passwords frequently makes no sense (Score 1) 563

People who argue that changing passwords frequently* is a waste of time has not had to deal with the security issue of people sharing their passwords on a regular basis. On the odd occaison, the Receptionists will share passwords so they can log in on each other's computers and access each others files.

And why do these receptionists still have jobs after repeatedly and willfully violating the security policy?

I'm not joking. Once, twice, three times is grounds for education and maybe a written reprimand, but if they even get close to double digits, either they should be looking for a new job, or you aren't serious about security and should stop pretending.

Comment Re:Reading is harder on a monitor. (Score 3, Insightful) 186

I have to think that this is because so many people insist on using dark text on a light background, which means that you effectively end up staring into a lightbulb all day long -- of course you miss things!

I see people talking about studies which show that dark-on-light is easier on the eyes, but every one I've actually seen data for was for _non_-backlit surfaces.

(Other possibilities include the fact that the spacing between lines -- leading -- needs to be proportional to the length of the lines, which it's not on any computer I've ever seen).

'Usability'? As far as I can tell, Ubuntu doesn't give a damn about usability, or they wouldn't have broken wireless on *both* the last two releases (10.04, anyone using a rt2870 based card on a WPA2 network was out of luck, 9.10, anyone using a WPA2 network period (or was that WPA at all? I can't remember) was out of luck, because the version of NetworkManager forcibly installed (never mind that the copy of wicd I had installed worked fine, Ubuntu knew what I needed better than I did, so it helpfully uninstalled it) couldn't handle it).

I've run Debian *unstable* on my server for the last decade or so, and I've never had this kind of problem.

Comment Re:Absence of Evidence (Score 1) 807

The problem is not, nor has it ever been that lunatics with their hand out the window yelling, "it feels fine!" are shouted down or ignored. The problem is that over the past 20 years the understanding has evolved that there is a "correct" result, and anyone working to disprove that result is an enemy to be scrutinized, tied to suspicious parties and ostracized.

By contrast, there are respected scientists in every other field attempting to disprove established theories, and should their work pan out, they would publish without fear of immediate rejection by their peers.

You're absolutely right; that's why people attempting to make perpetual motion machines are respected members of the scientific community.

I have worked for large companies in the past, and SOX is seriously undermining the ability to make changes, or indeed for rational process to take place in the daily operation of IT.

It's doing no such thing. People may be using it as an excuse to build an empire or do stupid things, but that's not the fault of SOX. I worked for a *VERY* large financial company (the overall IT budget, across all branches, businesses, etc, was measured in the *billions* of dollars), and not once were we stopped from doing anything because of SOX. Not once was it even an issue, either.

Put the blame where it belongs, on stupid people. Then fire them.

Opposing DRM is not some kind of religion, it is not even a moral position,

Opposing DRM is most definitely a moral position, on any number of grounds, starting with the ones you don't want to acknowledge down to the less obvious ones, such as opposing anything that makes life more difficult without providing any benefit or opposing the conflation of 'buy' with 'rent', as you never actually buy anything with DRM, you simply rent it.

Feel free to pretend you aren't doing anything wrong when you say there's nothing wrong with DRM. Just be aware that that's exactly what you're doing -- pretending.
