Anyhow... the MPAA say that they think P2P networks could be good for the entertainment industry and "It is only this illegal activity that the MPAA is fighting against"
Well, I only got a B+ in dram because I forgot to relate to other industries but never mind, and I don't see how 'fair use' and 'remote distributed archival' are illegal.
She also starts off with.... "When people upload or download others' copyrighted works, that is, in fact, illegal." Wrong, how else would I ever get anything off of the internet, what about caches? Also, lokitorrent didn't share anything it wasn't allowed to under copyright law.
Anyhow I lot my rag a bit, so It looks like I'm going to have to create a new email address to get the answers to those questions.
NOTE: not one use of the word 'consumer' and the only thing the email says is illegal is the 'distribution of a work without authorisation from the copyright holder', I said I'd see her in court over that vs my right to fair use, backups etc...
================= Dear Oliver,
Thanks for your e-mail.
While Peer-to-Peer (P2P) networks allow for a great deal of opportunity for distribution of entertainment, P2P networks unfortunately enable massive amounts of pirate activity.
When people upload or download others' copyrighted works, that is, in fact, illegal. There is nothing illegal about P2P technologies, if you're sharing work that you have the rights to share. But, most commercial works you find available on P2P networks (e.g., albums you find in stores, movies you find in theatres or stores) were not posted there legally.
It is only this illegal activity that the MPAA is fighting against. We will continue to embrace technology and the opportunities it offers responsible citizens using it legally.
Thanks again for writing, and please let me know if you have additional questions.
1. Cold start Doesn't exist in IE and konqueror it's embeded into the OS.
2. Warm start Doesn't exist in IE and konqueror it's embeded into the OS.
3. Rendering CSS Great tests except, how well do both browsers follow the specification, and how fault tollerent are they?
4. Rendering table
5. Script speed As will CSS, it doesn't mean shit if the browser doesn't comply with standards.
6. Multiple images.
Should have stored the data locally and cleared out the browsers cache, too much error in this test.
7.History
Next time try it with 1000 1024x1024 jpegs on each page.
What I want to know is. how good are the browsers under load. I known that Firefox and Konqueror choke if the active page and all embeded is too big e.g. a 100k page with links to 1000 1024x1024 jpegs.
How good are the browsers when I have 50 tabs open, because I haven't closed them all day.
Testing is all well and good, but when you browser starts running slow because of all the viruses you've picked up you'd wish it was a built a bit better instead of a little faster.
Look at it this way: Ok, I, a company, A company is never I but I'll pretend that companies are real..
places protection on a work that prevents it from ever being released into the public domain. Which is against the law.
You are not allowed to copy it, so you, being mindful of the law Which is that I am allowed to copy it and that it will be released into the public domain.
don't. It then never appears on any of the major file-sharing networks, and the work never spreads. There are lots of things it doesn't do, why pick on 'major file-sharing networks' my blind grandmother can't 'read' her Ebook either.
Meanwhile, you, another company, release your work on CD without any copy protection. Yes It enters into the public domain as people copy the music and share it online No more that me tapping my foot to the music I'm listening to at work.
it spreads, and a good portion of the people who listen to it like it enough to buy it Which just goes to show you can sell works that are in the public domain.
I like this law, personally; it will discourage copy protection, as in the long run those who embrace it fade into obscurity while those who publicly release their work gain widespread fan bases.
While I see your point, after a while 'most' people will try to become the dictators themselfs and embrase the new law. (hey there getting that benifit, but I'm not, not fair).
There will still be some movement of the more liberal kind like Linux but things like SCO and Patants will try to make that impossible only leaving the dictators left.
Your argument is I like patents, I think that is good America has patents because soon they will be behind the rest of the world... well unless Europe passes strong patent laws and India and China join the boat, in which case were all fucked.
In reply to myself. This breaks European laws, where are expressly allowed to reverse engineer for the purpose of interoperability.
fuck'em don't even bother them with your thoughts, when the first case comes to trial and doesn't get thrown out, rent a nice big truck, fill it full of agrigate and drive it straight through the house of the Judge or your local politician.
I a company places protection on a work that prevents it from ever being released into the public domain (non-key escro DRM) then you are not allowed to copy it fullstop.
Do they realise what they are doing or saying or are they in the pockets of the media
Thank-you for shutting down one of my most frequently used online backup sites www.lokitorrent.com.
You and your members have now permanently lost at least 2 paying customers with a collection of over 500DVDs to our name who used to frequently visit the cinima.
Well done, give yourself a pat on the back.
And yes I do have more than 500DvD's a few hundres computer games and an untold number of CD's.
emailing all MPAA members until they have so many complaints they cannot use there email properly. Don't hide like the MPAA want you to, let them know how pissed off you are. you could even walk around with a 2' by 3' sheet of yellow card with anti-MPAA info on it for a day, I collected 300 signitures against my local starbucks this way.
I for one used Loki as a 'backup' system, my Ultima 9 cd is scratched and the torrent for it was incredible useful.
Don't forget that the MPAA are upto something far worse than shutting down deeplinking sites, DRM. DRM has the power to replace copyright laws with something even more draconian, a system where nothing ever gets into the public domain, if nothing else DRM is in breack of existing copyright laws if it doesn't implement a time-release escro system.
the UNSC came up only very late in the 'how the fuck are we going to get away with this' argument.
What was funny is that the US and to some extent the UK didn't believe that Sadam had disposed of the WMD's and were banking on their belief as a reason for war, only to look a laughing stock when they found out that Sadam had disposed of them and pulling plan B 'UNSC resolution 678' out of the bag.
Time to put the tinfoil hat away lads, they know nothing.
I'm glad to see you still actively support the ideas of Native American Indians, or was I correct the first time in thinking you supported the ideas of the genocidal people who wiped them out?

"More than the US" ok, but how many of them work, you have to maintain NUKES or they degrade, the US have been activly maintaining them, has Russia?
"Of course they are, did you think they would build it and hint at not dropping it? "
What's the point of the original comment? It every country that has nukes says the same thing so the comment the original comment was pointless except to be prejudice.
"What scam exactly is the US running? " You obviously live in the US or you would have noticed all the scams they run, RIAA, Patents, the international bank,invading more countries than any other nation (though the UK and China come a close second) etc... does Nike still make shoes in sweatshops? does wall-mart have appalling working conditions, did the US appoint the Iraqi and Afghanistan governments and setup pro-US policies?

I think the biggest communist threat to the US is Bush. and never underestimate what you don't understate, wait till you up to you fat necks in legal battles and patents, and the oil starts running dry then come crawling in your wheel chairs asking the rest of the world to help you.
"Russia still has more nuclear bombs than any other country. They went more for 'quantity' in the cold war why the US went for 'quality'. "
How many working bombs does it have left?
"Please, enough with the reactionary Bush bashing. He's not dropping 'the bomb' on anyone. If he didn't do it post 9/11 it's not coming unless the US faces nuclear attack from an actual state."
That's what North Korea are hinting at too.
"North Korea is just running this scam for all it's worth to get more foriegn aid for it's starving populace and to ensure that South Korea is no threat. This has little to do with US foreign policy in the middle east over the past few years.

Advertising works for people who buy cans of coke. The average UK IQ of Internet people who take the IQ test from that advert that pops up occasionally it 115. Lets assume people with an IQ lower than 110 buy coke partly because of advertising (well I don't know why they would otherwise), that's still a lot money from a lot of idots.
Advertising isn't worthless, just like the RIAA isn't worthless. (if you read the RIAA/MPAA crap it says that Advertising and Payola it one of the largest costs of the music industry)
Hmm.. what moron got mod points. I would have made the don't mix feet and meters joke but someones already done that. NASA is a big money sink some something for the 'troll' especially when you consider how well other countries have done with a far smaller budget. (e.g. the haven't blown up too many shuttles!) This is with the exception of that Guy from the OU who responsible for Begal 2, there was a reason no-one would back him, probably the same reason the mission failed.
Sounds like a 'next time it will be you head' warning to SCO to actually produce some evidence to back up it's claims, and also give IBM something to clean out SCO with after the trial.
'This is an operating system feature, not an application programming feature'
Wrong, the JVM could implement copy on update easly because java doesn't provide pointers, as it is it tries not to duplicate duplicate strings. And I can easily overload operators in C++ and make the pointers private to exactly the same effect, sure I can hack around if if i want, but the I can do: int *a = 1; *a = 10; too.
the VM uses page faults to perform copy on update, in C++ you can use operators.
When it's large trees of data and not just strings that you dealing with copy-on-update is so much nicer than copy the whole lot, and it's easy to turn the copy-on-update code into a deltaring system with rollback (kind of undo-redo)
'Also, copying the string rather then using a pointer is simply a safer way for a programmer to perform this function.'
Which is why I always use it for prototyping.
' Due the complexity of most modern software' lack of modularity and encapsulation yes....
' a single programmer' collage grad...
'would probably not know if using a shortcut like this is safe. ' doesn't know how to use encapsulation and documentation to make sure it is safe.
' What if some function that this string is passed to actually DOES change the string occasionally' apart from multi-threading, in which case use critical sections, or you OS equivilent I don't see what you getting at. is there a function that's documented my function((in) char *) when it should be my function((in-out) char *) that's why I said documentation is an important part, and that's also why I said collage grad. Also encapsulation would help a lot (no char*'s).
' This can introduce very tricky and difficult to find bugs especially if these shortcuts are used everywhere.'
I didn't say use them 'everywhere', just like I didn't say copy the data 'everywhere' only a fool would copy the data all the time and only a fool would alias pointers all the time, why should my computer be at least twice as slow and memory hungry as it could be if the software was written by people who knew what they were doing.
this probably explains why there are so many bugs in production software too, most programmers can't programme, don't write documentation, and think regression's something that happens when the stock market crashes.
True, speed isn't everything, bandwidth counts for a lot, and their putting a few of these puppies in the console.
Also when your talking about graphics or vector processing that consoles are going to perform then raw power is what matters, not how fast you can task switch or perform string operations.
Cell processing allows the console to be bad at somethings bad not to get bogged down by them..
Now, if only QT would get their act together and make their GUI code thread safe.
That's the point, implementation not algorithm, the algorithm is 'high level strings'
a = "hello this is a string" position = scan(a until [a] =" ") b = pointer( a + position)
a = "changed" b == ???
Did you not read, 'copy on update' (I think I missed out the o)
a = "changed":=
copy_on_update(references_to(a)); set(a to "changed")
results in b = copy_data(from (a + offset) to lengthof(a) - offset) a = "changed"
Often your never going to update b, so pointing into a is ok.
Secondly if your being pedantic, "hello this is a string" is static so a pointer into it will always be ok.
There are lots of other good examples using strings, e.g. if your going to check the length of a string, or concatenate strings a lot then you'll want to use a pascal style string as apposed to a null terminated one.
modern c libraries provide strn and...f("%.ns",length,string);
I down known what std::string uses, but one of the greatest speed improvements I've ever had was replacing some std::strings with pointers into blocks of data and some data/pointer management code.
I wasn't arguing so much C vs Assembler, more high level languages and libraries vs knowing whats going on. 'most' programmers use high level libraries and wouldn't know what to do with a unsigned short * if it hit them in the face.
Just look at the code to KDE and QT (if you can get round the horrible single charter variable names), and that's even before we get to the likes of VB,.net, java, javascript, xsl, cobol etc..

I didn't say use them 'everywhere', just like I didn't say copy the data 'everywhere' only a fool would copy the data all the time and only a fool would alias pointers all the time, why should my computer be at least twice as slow and memory hungry as it could be if the software was written by people who knew what they were doing.
this probably explains why there are so many bugs in production software too, most programmers can't programme, don't write documentation, and think regression's something that happens when the stock market crashes.
True, speed isn't everything, bandwidth counts for a lot, and their putting a few of these puppies in the console.
Also when your talking about graphics or vector processing that consoles are going to perform then raw power is what matters, not how fast you can task switch or perform string operations.
Cell processing allows the console to be bad at somethings bad not to get bogged down by them..
Now, if only QT would get their act together and make their GUI code thread safe.
But your code fragments are NOT equivalent.
:=
...f("%.ns",length ,string);
.net, java, javascript, xsl, cobol etc..
That's the point, implementation not algorithm, the algorithm is 'high level strings'
a = "hello this is a string"
position = scan(a until [a] =" ")
b = pointer( a + position)
a = "changed"
b == ???
Did you not read, 'copy on update' (I think I missed out the o)
a = "changed"
copy_on_update(references_to(a));
set(a to "changed")
results in
b = copy_data(from (a + offset) to lengthof(a) - offset)
a = "changed"
Often your never going to update b, so pointing into a is ok.
Secondly if your being pedantic, "hello this is a string" is static so a pointer into it will always be ok.
There are lots of other good examples using strings,
e.g. if your going to check the length of a string, or concatenate strings a lot then you'll want to use a pascal style string as apposed to a null terminated one.
modern c libraries provide strn and
I down known what std::string uses, but one of the greatest speed improvements I've ever had was replacing some std::strings with pointers into blocks of data and some data/pointer management code.
I wasn't arguing so much C vs Assembler, more high level languages and libraries vs knowing whats going on. 'most' programmers use high level libraries and wouldn't know what to do with a unsigned short * if it hit them in the face.
Just look at the code to KDE and QT (if you can get round the horrible single charter variable names), and that's even before we get to the likes of VB,
