Someone mod parent up. Indeed, if users can install stuff, their machine becomes unusable very quickly. Not only in large corporate environments. In small ones too.
And even if only "power users" know the admin password to install stuff, what I see is:
- Screen capture programs installed, because nobody noticed the key labelled "PrtScr" on their keyboard (let alone finding out about Alt-PrtScr).
- Winzip or whatever installed, because people didn't realize that Total Commander, which they use for FTP, could seamlessly handle.zip,.7z and whatnot. (Yes, I pre-install Total Commander with a.7z plugin)
- Old cracked versions of Photoshop to resize jpegs and convert tiffs, because people don't realize they can do the same thing faster with IrfanView or XnView (which were both pre-installed for them).
etc.
That is the "best case" scenario, where they don't install malware, and silly "media converters" straight from the ffmpeg "hall of shame".
The spam I get uses forged headers anyway, and was sent from botnets.
So even if abuse@(yahoo|gmail|hotmail|whatever) would cooperate, there is nothing they can do about a bot sending directly to the recipient's server with a fake From: header.
All this plan could accomplish would be to suspend perfectly innocent email accounts from people who were unlucky that their address was used in spam headers.
I've been hearing about DNSSEC for quite a while now, but still don't understand if I need to find out more and possibly do something about it.
I take care of about a dozen small zones under various TLDs. The DNS servers for these zones are all running Bind 9 on Debian. None of the domains has a real certificate, but they all use self-signed certs for things like mail with SSL/TLS, VPNs, etc.
I also manage company DNS servers, which are the resolvers for the machines on the LANs.
So, is there anything special that people like me need to know or should be doing? Or can we just ignore DNSSEC for now.
Libertarian is a form of right wing extremism, Liberalism is middle-left.
Viewed from continental Europe, the US liberals look exactly like the standard right here. The US Republicans (without the Tea Party loonies) would be considered extreme right in Europe. Even though even the European extreme right takes universal health care for granted.
I'm not sure if there is any party in Europe defending the Libertarian ideology of destroying government (and let mega corporations rule over anything they aren't already).
Your AVI files are not DVDs (IFO, VOB files in a VIDEO_TS folder), even if they happen to be burnt on a DVD. And they most probably aren't even Mpeg2. Mine can also play a few fancy formats, but that has nothing to do with the Video DVD standard.
your DVD player cannot display an arbitrary frame rate either.
Can you explain why you say that? What limits them?
Although the DVD format spec limits the officially supported frame rates, there is no technical reason that the player cannot support additional frame rates.
Theory vs reality. You could easily build a DVD player accepting different frame rates. But the ones we all have at home will not display an MPEG2 file with a frame rate of 48, or 72 or whatever fps, because the DVD standard requires a frame rate of 25 or 29.97, interlaced or progressive.
In theory, projectors could use any frame rate. In practice, while many home projectors for Super8 mm. had a variable frame rate, professional 35mm projectors in theaters dont. DCP projectors use fixed frame rates as well, and your DVD player cannot display an arbitrary frame rate either.
30/60 is only good in the US and a few rare other 60Hz countries. It doesn't convert well to 25/50 which the rest of the world uses (either you pay fortunes to have every single frame re-calculated to get 24 brand-new frames per second, or you just drop every 6th frame and get a terribly jerky 25fps result).
And requires the horrible 3:2 pulldown (or whatever it is called), to be projected in any movie theater at 24 fps.
No, 30/60 is not "forward looking" at all. Quite the opposite: it's backward looking at the history of US TV.

A billion years ago the FBI had a news conference about WEP security which is anything but secure, and demonstrated it can be broken in 2 minutes
.
Well in practice, it's more like 10 to 30 minutes, once you are used to doing it.
First you need to find a WEP AP, and where I live, they are few and far between. Everything is WPA or WPA2. Then it has to be not too far away so that you have a good signal. Then you need a supported network card. USB wifis are cheap, but you may have to try several until you find one that actually works for injectionj. Then you need various software (or a Backtrack VM) and know how to use it.
Once you have the right wifi card and have put together the right software and learned how to use it, if the WEP AP is not too far, you may be able to get the key in about 10 miinutes. In 2 minutes, I can hardly just find my USB key, plug it in and start the VM. And at that point, I don't even know yet which AP on which channel I would want to crack.
I was probably a bit unclear. By "normal people who export videos", I didn't mean just "normal people.". I meant the normal users of Final Cut, Compressor, and the like. The ones I know already struggle and call me for help when they need to export an H264 or make a DVD. I their usual tools don't have easy presets for WebM, that wil definitely be a problem.
OK, so it may eventually work in all browsers if everybody installs the plugins.
But how do you encode the stuff in the first place? I'm sure I can do it with ffmpeg, but what about the normal people who export videos?
They are used to Quicktime exports from Final Cut Pro, or through Compressor, or maybe MPEG Streamclip or Handbrake. If Quicktime doesn't support it, then the simple direct export from FCP, or using MPEG Streamclip will not work. I wonder how this problem will be addressed.
If using TKIP/PSK (like most home users, and all my neighbours), there is no difference:
"But I use WPA2 so it's cool right?
Actually, while WPA2 introduced CCMP mode as a replacement for the problematic TKIP, when run with authentication based on Pre-Shared Keys (PSK), it is still vulnerable to dictionary attacks. Our service works against both WPA and WPA2 when PSK is being used. "
I meant user_pref("dom.disable_window_status_change", false); of course.
But anyway, it still doesn't seem to work to show a fake link. And it doesn't work in Chrome either. I guess it used to work in the good old times of MSIE 4?
Sounds fun, but does it really still work in current browsers? In Firefox, it is disabled by default. You can enable it with user_pref("dom.disable_window_status_change", true);
Meld actually uses diff. But it then displays the results in a practical and clear interface for reviewing which change to keep and which not. diff/patch and Meld serve very different purposes, so your remark doesn't make much sense.
That last time Kodak had a good viable product would have been the very early 90's.
Sorry, but you are wrong. Kodak is still very relevant in motion picture film. Their latest camera films were introduced in 2009 and 2010 (Vision 3).
And film is often still the preferred original in motion picture production, if you can afford it + a digital scan for post production. It is not only preferred because the cameras and accessories are so good, but also because the film itself captures better pictures in most situations, or is easier to work with in high contrast lighting. Here is a recent comparison with the RED One.
As for digital, Kodak introduced the first film scanner in 1993 (the Cineon), and the.DPX files used in digital post production today are directly derived from the file format Kodak introduced with the Cineon.
In their field, this was and still is an innovative company doing fantastic professional products.
It would be a pity to see them end as patent trolls.

I haven't heard of a K-12 school teaching logic or philosophy. So yes, reasoning and comprehension does need to be taught at the higher level.
If that is really so, it would explain a lot about US politics, and the nonsense some politicians can get away with, and still be elected.
(I guess K-12 means students around 18 years old, in their last year of school before university? If not, please correct me.)
Yes, there is only one, but that's for Perl 5. The new Perl 6 book is almost ready.
That's like saying 'A trip from Tuscon to Texas.'
Except that Texas is almost 17 times larger than Switzerland: 696'241 vs 41'285 km2.
A recently installed server in a small company (Debian Squeeze):
$ find /bin /sbin /usr/bin /usr/sbin -type f -exec file "{}" \; | grep 'perl .*script' | wc -l /bin /sbin /usr/bin /usr/sbin -type f -exec file "{}" \; | grep 'python .*script' | wc -l
196
$ find
46
My notebook (Ubuntu 10.4):
$ find /bin /sbin /usr/bin /usr/sbin -type f -exec file "{}" \; | grep 'perl .*script' | wc -l /bin /sbin /usr/bin /usr/sbin -type f -exec file "{}" \; | grep 'python .*script' | wc -l
398
$ find
134
Of course, some may prefer Perl to grep + wc (it's faster too):
$ find /bin /sbin /usr/bin /usr/sbin -type f -exec file "{}" \; | perl -ne '/(perl|python) .*script/ && $$1++; END {print "$perl perl\n", "$python python\n"}'
398 perl

In Tchernobyl and probably in Fukushima, they have heat sources which will last for a very long time. Maybe this heat pump could be of use there...

Finally, I understand why we need Category 6 Ethernet cable. Because it "is re-enforced to survive a Category 5 hurricane".
And that's also why IPv4 is not good enough and we need IPv6, I guess.
