The IPv4 Internet Hiccups

Lord Crc Re:Yes, Please (248 comments)

Here's from my router:

                    IPv6 Connection Type: Native with DHCP-PD
                            WAN IPv6 Address: 2a02:fe0:c400:1:95d2:656f:...
                            WAN IPv6 Gateway: fe80::219:2fff:fee6:73d9
                            LAN IPv6 Address: 2a02:fe0:c411:a960:da50:e6ff:.../84

My PC gets a fe80 address, but I can ping the "LAN IPv6" address above.

The IPv4 Internet Hiccups

Lord Crc Re:Yes, Please (248 comments)

My ISP supports IPv6, my router supposedly supports IPv6 (Asus RT-N66U), I can see the router getting an IPv6 address from my ISP, I can see my PC getting an IPv6 address from my router yet when I test it out on the various "do I have IPv6" pages it's failing.

After spending a couple of hours mucking around I gave up. I'll deal with it when it matters. Hopefully it's less painful then.

Verizon Now Throttling Top 'Unlimited' Subscribers On 4G LTE

Lord Crc Re:what the hell are you doing on your cellphone (274 comments)

If I'd listen to di.fm on my way to and from work, which takes me about an hour each way, it would be about 4.6 GB per month just there.

Now if I paid for an "unlimited" plan, I would expect such casual usage to be perfectly within the bounds of "unlimited".

Researchers Find Evidence of How Higgs Particle Imparts Mass

Lord Crc Re:Erm (91 comments)

Indeed. Only a small fraction of the collision events are kept, otherwise the amount of data would be overwhelming.

From http://www.lhc-closer.es/1/3/13/0:

In particle physics, a trigger is a system that uses simple criteria to rapidly decide which events in a particle detector to keep when only a small fraction of the total can be recorded. Trigger systems are necessary due to real-world limitations in data storage capacity and rates. Since experiments are typically searching for "interesting" events (such as decays of rare particles) that occur at a relatively low rate, trigger systems are used to identify the events that should be recorded for later analysis. Current accelerators have event rates greater than 1 MHz and trigger rates that can be below 10 Hz.

Netflix Is Looking To Pay Someone To Watch Netflix All Day

Lord Crc Re:Netflix rating engine sucks (86 comments)

Well the problem is that when I rate a movie, Netflix has no idea why I rated the way I did. They don't know the context.

I recently rated a movie 1 star, I didn't even finish it, because the story was just so horribly badly written. But I liked just about everything else, the plot itself was great, my kind of genre, cinematography was good, actors too. But that stupid story just killed it for me.

How's Netflix going to figure out why I rated that a 1 without asking me? I think they should ask follow-up questions to get some of that context if I rate a movie very different from their prediction.

But yes, if I've recently watched a movie... don't recommend it to me again for some time. That'd be a good start.

Mysterious X-ray Signal Hints At Dark Matter

Lord Crc Re:It's always dark matter. Except when it isn't. (100 comments)

Dark matter is one of those as well. They've theorized dark matter and attributed each unexplained item in astrophysics to it but have no real evidence it exists.

No. You got it exactly backwards. It's entirely the opposite of string theory. String theory was born as a theoretical construct and they're trying to figure out how to make predictions with it so they can see if it matches the real world.

When it comes to dark matter, what they have is a ton of observations which does not match the predictions of our current theories. What they see is mass being affected by something we can't see. So they've given it a label until we figure out what it is: dark matter.

So, just to repeat, dark matter is just a label given to what we can see happening but which we cannot currently explain with our established theories (GR and Standard Model). Hence it absolutely is reality!

And no, having "enough" dark matter would not explain the big bang. However certain dark matter theory-candidates give predictions which can explain the matter distribution in the galaxy, which neatly solves another puzzle.

You can read up on some details here about the latter: http://www.illustris-project.org/about/#public

Driverless Cars Could Cripple Law Enforcement Budgets

Lord Crc Re: Just Tack on a Fee (626 comments)

Previously mentioned steering wheel attendants who aren't paying attention will swerve right into your side because they weren't paying any attention!

Sure, but if they instead swerve right in front of you, and you are speeding, you will hit them with significantly more energy than if you were not speeding, making the collision significantly worse.

Driverless Cars Could Cripple Law Enforcement Budgets

Lord Crc Re:Just Tack on a Fee (626 comments)

Speeding being dangerous is a commonly believed myth.

Physics would like to have a word: E_k = 1/2 * mv^2. If you're speeding by 15% your car has 30% more kinetic energy. If you're doing 90 rather than 65, your car has almost twice the kinetic energy.

No amount of paranoia and adrenaline can change the fact that you now need twice the breaking distance.

Did the Ignition Key Just Die?

Lord Crc Re:Help! Help! (865 comments)

Must have been your pedal getting stuck or the cable. Not the throttle. The pedal only opens the throttle by pulling a cable.

Just for the record, the pedal is not the only thing that can pull on the cable. The carburetor can pull on the cable if it's mounting has come lose. This happened to my gf's car, and the gas pedal would quite literally get pulled in with it, while the engine rev'ed at max.

Supreme Court Makes It Easier To Get Lawyers Fees In Patent Cases

Lord Crc Re:400 years for one murder (51 comments)

I deliberately left out "forvaring" as it's not intended to be a punishment. It's a means to keep people who are deemed too dangerous off the streets.

My point was that perhaps the punishment should fit the crime, so to speak, even if the resulting number of years sound a bit silly.

Supreme Court Makes It Easier To Get Lawyers Fees In Patent Cases

Lord Crc Re:400 years for one murder (51 comments)

Why in god's name would you sentence someone to 400 years in prison unless you believe in Highlanders?

Here in Norway, the maximum sentence is 21 years, and doesn't stack beyond 21 years.

First-degree murder has a maximum of 21 years. So, you could have two guys in jail, both serving 21 years, one which murdered one person, the other which murdered say 69.

Now, I believe that taking 69 lives in cold blood is significantly worse than "just" one. However the sentence does not reflect this.

So while 400 years for one murder is a bit much, sentencing the second guy to 69 * 21 = 1449 years in prison would at least more accurately reflect the crime he committed.

How many of those years he must serve could be orthogonal, if society wants it that way.

Blender Foundation Video Taken Down On YouTube For Copyright Violation

Lord Crc Re:Stop using Youtube (306 comments)

Content-ID picked up the infringement of audio, but for music that was so ancient (Any older and it'd be on wax cylinder!) as to be public domain even in the US. I looked into it - a collecter's society had claimed the rights to it, even though the composer was dead more than seventy years ago

How old was the recording you used? The song/tune itself can be public domain due to age, but the performance/recording will still be protected by copyright if it was made recently.

Dropbox's New Policy of Scanning Files For DMCA Issues

Lord Crc Re:Much, Much Later (243 comments)

I refused to use Dropbox ever since its "end to end encryption" claim was shown to be false, and they were de-duping your files.

I simply never assumed my Dropbox files were private to begin with.

While I don't share everything in my public folders, I don't put anything in Dropbox that I don't mind the whole world to see.

Making Sure Our Lab Equipment Isn't Tricking Us

Lord Crc How about not-quite-random numbers? (108 comments)

Why can't they use a PRNG to dictate the detector settings? Pick a high quality PRNG, seed it with the first prime number. Run the experiment N times. Restart, seeding it with the second prime number, and run the experiment for N times again. Repeat M times until satisfied.

Then re-run the above with a different type of high quality PRNG.

Am I missing some big clue?

Firefox 27 Released: TLS 1.2 Support, SPDY 3.1, SocialAPI Improvements

Lord Crc Re:Yes, but have they fixed the crashes? (167 comments)

Maybe it's me, but Firefox 26 would crash at the drop of a hat

Tried running it in "safe mode" without addon's and see how that goes?

Firefox still crashes for me when it runs out of memory due to buggy javascript in either an addon or on a page. For example we use FinalBuilder at work, and the build control page has a massive memory leak in the javascript (sucky dom handling in web 2.0 crap) causing FF to run out of memory if I leave the page open over night.

Other than that it's been very stable on all the machines I've used it on for many years now (and that's both Windows and Linux).

Not All Bugs Are Random

Lord Crc Re:No (165 comments)

the seemingly random bug is in fact deterministic and only triggered under certain unintentionally well-defined conditions.

The faulty code is of course fully deterministic. The resulting output may be completely arbitrary.

Not All Bugs Are Random

Lord Crc Re:Obvious, but worth restating. (165 comments)

Are any bugs truly "random"? I always thought computers were deterministic machines.

If your code contains a state machine and the code has a bug where it in some conditions references invalid or uninitialized memory to determine it's next state, then the bug may appear quite random. In fact, it may appear to be several different bugs.

This is particularly fun when doing cross platform programming, where some platforms always zero initializes memory upon allocation causing programmers who develop on those platforms to think everything is peachy, only to have the code promptly crash or worse when run on platforms which does not zero initialize memory.

NYT: Healthcare.gov Project Chaos Due Partly To Unorthodox Database Choice

Lord Crc Re:follow the money (334 comments)

They should have just used MongoDB. I hear it's web scale.

Web scale or not, I have no idea. But I do think they've got the best bug report ever in their tracker.

WxWidgets 3.0: First Major Release in Several Years

Lord Crc Re:Is it still relevant? (147 comments)

If you don't have experience with a platform and can't debug on it, how can you offer a trustable software for it?

Because we use portable libraries and code, and we have plenty of testers.
