While a very few channels (mostly the networks) try to increase return on investment by spending more hoping to attract more viewers, the majority of channels try to increase return on investment by spending less hoping to get the same number of viewers.
Given that by far most content on TV is not original, but licensed from someone else (typically a repeat), the key is to OWN YOUR OWN CONTENT. This is why ESPN created the X-games, because they own all the rights to the event and can show the content in reruns forever for free.
More recently, they (and everyone else) have jumped on poker. You don't actually have to pay anyone who is in the tournament, it's a pari-mutuel, they pay each other. You only pay the cost to film it and then show it over and over and over.
So of course they'll jump on televising compute gaming. No one in the events owns their own publicity rights, so you either put on the event or buy the rights from the people who do put it on and you're home free with some cheap content.
But don't get an idea it's because of some sudden maturity of computer gaming. It's more because the immaturity of computer gaming means the "athletes" don't get paid squat. It's just another form of reality TV, just like sporting events and awards shows. Think of it as "Survivor" with WASD.
Okay, Kutaragi's comments about getting a 2nd job were insane. No two ways about that.
Two SKUs is to lower the entry price. Just like on the 360. It worked for 360, got it over the high entry price hurdle. Obviously the PS3 needs it twice as badly. Of course, the low-end PS3 cannot be upgraded to match the high-end, unlike the 360. This is very bad, that means Sony has to be more careful about the ratios of the two units, as many people will not buy the lower end unit as a replacement for the upper end unit, knowing they are stuck for good.
Enforced BluRay is only a bad thing for the first Christmas, as it raises the price. After that, having a standard storage format that is bigger than 9GB will very much benefit the platform. Also not having to spin the drive at 8X will make it a lot quieter than a 360.
Rumble doesn't matter to me. Who cares if GTA4 is exclusive when Saint's Row is a very accurate knockoff of GTA3 anyway? Delay's to PAL regions are bad, but the 360's "world wide release" was worse. With 3 regions launching on 360, that meant no one was able to get a unit. Imagine if it took off in Japan! There would have been 1/3rd again fewer units to buy in the US before Xmas.
The rumors about developer comments are just that, rumors. And screen shots showing the graphical power? Did you play the Tiger Woods game that came out with 360? It looked no better than the original Xbox. Does that mean the Xbox 360 graphics aren't any better than original Xbox?
The unit is smaller than 360 overall, because it has an internal power supply. 360's power supply is the same size as a Wii and is external. PS3 still has that stupid football-shaped cross section though that means I can never set anyting on it. I thought 360 was a dumb shape, but this really takes the cake.
I think the mockup had 4 ethernet ports actually. The production PS3 does 7 controller IDs at once, although Sony seems to be using some controller IDs for things other than controllers. But I don't get the beefing over the ports. It's not like Sony ever shipped any like that, nor did they announce a price. So how you can say you're being gypped over something you never had an actual chance to get? Additionally, anyone who had any clue knew immediately the unit would not have all those ports. Ethernet ports cost at least $0.50, and no one actually responsible for production is going to put on $1 worth of ports no one would ever use.
Additionally, 360 was not shown "suprisingly complete" at E3 that year. There was not a single working model to be found. Games were shown playing on Macintosh G5 towers.
Sony and MS did get into an escalating war of words over what they would deliver. If you ask me, MS' J Allard was the biggest force in it. He made a lot of bonehead moves at that E3, saying stupid stuff like "Live will be free" (it's not), "it'll be backward compatible" (it is for Halo and Halo 2, but the actual compatibility is actually very poor) and promising the unit will have 512MB of RAM, a move that halved MS' production well through Xmas, as RAM available was the constraining factor on production. With each unit taking twice as much, have as many units could be sold.
In the end, this war of words really raised the level of what the next gen of consoles would deliver to the customer. But it also raised the price from both companies. You can't tell me Sony and MS initially thought $400+ was a great price to sell at. They just made promises and had to raise prices to fulfill them. If you ask me, all the price jumps on both sides (except for Sony's BluRay inclusion, with was already a sure thing) came from that war of words at E3.
Do you have evidence Sony's online system isn't nearly as capable as Live? Why do people get so excited over Live? Yeah, it's nice. No, it's nothing that any other company couldn't do, especially since they don't even have to invent it now, just copy it. Why exactly do I have to pay for Live? It doesn't keep the assholes off.
Does it matter what the cause is? If the temperature goes up, a lot of people in Manhattan will be unable to live there anymore. It appears that shifts in the ocean currents will make living in Europe a lot more difficult too.
So, even if the temperature going up is caused directly by the sun, it behooves us to fight it. Anyone who likes the planet like it is right now (esp. anyone near the coasts) has a reason to try to keep the global temperature the same. Because if the temperature changes, you can't be sure what will happen. Well, you can be sure of one thing, that is things won't be the way they are right now. Change is the only certainty.
Even if the sun is causing the warming, but we could counter it by reducing CO2 emissions, we should do it.
Actually, often it does imply causality. But it doesn't prove causality.
Henry's LaW [Gas solubility] _requires_ steady-state CO2 levels to increase with increasing temperature because of reduced gas solubility.
Not percentage-wise it doesn't. Yeah, the oceans will hold less CO2, but they also will hold less oxygen, less nitrogen, etc. There's nothing that says that the percentage of air that is CO2 has to go up with temperature.
Me, I've seen enough correlation to believe that we cannot afford to burn all the stuff in the ground that has been storing energy for years. Even if the CO2 released isn't the direct cause of the warming that follows, in the past is is likely the indications of CO2 increase in the past following the indications of temperature increase means that if one didn't cause the other, they have the same cause. And that cause could easily be the burning of carbon-storage structures (wood, oil, coal).
I don't think $150 is being passed on to the consumer either way.
Obviously Sony is bundling BluRay for their own purposes, not for the customer's advantage.
But honestly, there is one reason I'll be glad to have BluRay. A BluRay drive spinning at 1.5X has a higher transfer rate than a 12X DVD-ROM and will be a lot quieter.
So when I sit here with my 360 DVD-ROM drive making huge amounts of noise, I wish the unit were quieter. It's possible the PS3 will load games more quickly and will be more quiet than the 360 due to this BluRay format games.
I dunno if this is enough reason to pass $100 onto the customer. It'd be worth it to me, but think a company needs to set the bar higher than just pleasing people like me (who bought PS2+ units to replace their early PS2s just because they were quieter and took less power).
I still don't think Sony should ship an HDMI cable. It's a standard cable, just get one at the store, the one that you need. Because less than 40% of people will have use for an HDMI cable. Many would rather have an HDMI->DVI cable instead.
Wikipedia greatly endorses the Neologism (or perhaps Protologism according to their page) "initialism".
For some reason, someone decided to redefine acronym and make up a new word to cover what acronym covered before. And Wikipedia uses it constantly, despite the pointlessness of it and the fact that the word hasn't caught on widely, thus making it a protologism. Although protologism isn't a word that has caught on widely either, thus making it a protologism itself at best, more likely a vanity word.
Even if you are going to use digital video, many people have a DVI port instead of an HDMI port. So this cable not only isn't required for them, it's useless.
Additionally, you can play BluRay movies over the component out (people who buy the $500 model will have no other choice) until the image constraint token is adopted (which Sony swore off for at least 5 years).
It is astounding not only how poorly people understand HDTV, but the eagerness they show to share their incorrect info and predict gloom and doom based upon it.
See, that's the funny thing right ther, it's not "the necessary cable".
An HDMI cable would be useless for over 50% of the people who buy this thing.
A large number of people have no digital video input at all (and will use component). A large number of people also have a DVI input instead of an HDMI input and will need a HDMI->DVI cable instead of an HDMI cable.
Bundling this cable makes no sense.
Xbox 360 doesn't come with a digital audio cable, despite the much larger number of people who have digital audio (compared to digital video).
This is a stupid article, it's ridiculous to see the haters propagate it all over the web.
There are plenty of legitimate reasons to not like the PS3. There's no need to make up nonsense ones too.
I'm paying them a fuck ton of money to teach me, not to take roll.
Having to show up to class is detention, not learning.
There's plenty of things to learn in college, and one is you need to manage your own time and affairs. That means going to class because you know it's what you need to do to learn what you need to know, not because you'll be arbitrarily punished if you don't go.
The Acela electric trainsets introduced by Amtrak in the early 21st century, are 2.1 tons/seat. This is ten times higher than that of a lightweight auto.
That would mean 4200lbs/seat for the train.
So a lightweight auto would be 420lbs/seat.
So that's either a 1 seater at 420lbs, 2 at 840, 3 at 1260, 4 at 1680 or 5 at 2100.
The lightest cars out there are about 2500lbs (Honda Civic) and don't really hold 5.
A real lightweight car at 2500lbs with 1 person is 1.2 tons/seat. With 2, it's 0.6 tons/seat.
This may not be as much as a train, but as the rest of the article says, the friction of steeel wheels on steel rails is less than that of rubber tires on concrete.
If you actually correct both sets of figures for the vehicle not being full, and don't assume cars hold 25% more than they do and weigh 20% less than they do, it seems like trains do okay.
And on another note, he says that cars used to be 1/2 to 1/3rd as efficient as trains in the 60s, but cars got a lot more efficient. As is drummed into me over and over from other sources, cars are not getting a lot better mpg than they were back then. And I know they aren't carrying 2-3x more people. So where did this 2-3x boost in efficient come from? And was GE throwing money away when making their more efficient locomotive engines (esp. the new AC ones)?
Article assumes that many of the seats on a train are empty. But then also assumes that all the seats in a car are full. In fact, it assumes that a car has 5 useable (and full) seats and only weighs 2100lbs.
It baffles me that people write articles like this. Why skew things to prove a point. Make a factual article and find out what the results are as you go along.
They keep stating Apple is pressuring them, but Apple says they have not contacted Apple with any info.
They state they won't say anything until Apple patches the problem? It would speed up the process of getting it patched if they would tell Apple about it!
From what I can tell, they are pretending Apple is pressuring them because it makes them look more important.
Addtional note, what is this stuff about Intel's drivers? Apple doesn't use Intel's chipset, they use an Atheros or Broadcam WiFi chipset. Additionally, what good is getting your packet on the stack? Apple uses the NX bit, so you can't get code on the stack to execute.
I think instead of just using broken crypto and advertising as "uses 128-bit AES for maximum security", I'll instead do that AND insult others. I'll be sure to pass immediate judgement on others and state I know what their plan is without knowing anything about what they're doing.
Then I'll be following the example of you, it seems.
Thanks for the initial help. No thanks for the ivory tower bullshit.
I looked up my address. It listed several offenders. One was on a corner. I would go by the house and sort of try to catch a glimpse of the guy. But I never did. Turns out the house was being prepped for sale and it was then sold a couple weeks later.
But if you look up my address, the offender is still listed there.
The database is way out of date becuase sex offenders don't stay in one place long. Very few can get a decent job and so they don't buy houses, they rent houses or apartments. And of course they move around a lot.
Currently, not everyone knows the site is inaccurate, some still believe it. So it does have an effect on property values, even if it wrong. Over time, everyone will wise up and realize that the site is way off and just ignore it.
It always was just a feel-good thing anyway. One thing you can tell just by a quick look is you can't really move away from sex offenders (let alone keep them from moving in near you after you move in) unless you move away from society in general.
Unless your optical drive is riplocked, it will read the disc at 8X or more. Drives are a lot louder at 8X than a standalone drive that runs at 1X.
I have no idea how you say a decent HTPC is defined by where it is playing its content from.
My shitty Intel graphics aren't a bottleneck, they just aren't helping at all. They don't accelerate MPEG-4 or H.264 playback. As to your comments about high-end cards accelerating MPEG-4 and H.264, that wasn't the point. I did allow for this with my comments, but this is a long way from the GP's comment:
"And since relatively slow processors and low-end video cards today have more than enough power for HD video,"
A GeForce 7 is not a low-end card. Nor are the Radeons you speak of.
The GP's argument was wrong about most video cards and misstated how much CPU you need to play HD video. Your arguments do not refute this.
When the BBC posts an article about how this is a safe browser and it appears to be not true (in fact, perhaps it's Adware), then I think the article has risen to a high enough level that a refutal is in order.
Again, the system I'm on is not just a PC in a box. Performance is critical, and I can't use a two-pass system.
I'm sure it's great to have a ton of MIPS available and to be able to choose from many complex modes of operation, but that's not the situation I'm in.
Your judgement of wrong and right assumes you know all the tradeoffs. You don't. Please leave out your uninformed judgements. I just asked from some help on IVs, and as far as I am concerned, I got it. So if you think you can't help me further with the amount of information I am able to give, then I understand.
Let's consider this conversation between me and you over. I ask for help with one thing and instead of get criticism from people who don't know anything about the system I implemented (and I like it that way) insulting me as not even knowing as much as they got from reading a single book.
The useful part of this conversation is clearly ended and I don't see any point in hurling judgements at each other.
why am I hand-rolling my crypto?

Crypto Snake Oil
·
· Score: 1
I'd like to be funny and say it's because I've used OpenSSL, and I am astounding anyone (including myself) is capable of making a system that works with it, let alone is secure. It's a complete disaster.
But really it's because the system I'm using is an embedded system. And by embedded system I don't mean a full-blown PC running Linux, I mean a small system. I was allocated about 4,000 instructions for my crypto work (and an AES ECB accelerator).
In CTR mode, the each encryption doesn't depend on other data encrypted before it. Thus someone could change a single 128-bit area in the cyphertext and it wouldn't affect anything else. This greatly reduces the difficulty at changing my cyphertext to change the plaintext in certain areas without it being detected after decode.
I appreciate your info, but I think you're jumping to huge conclusions about my system. Again, in my system only about 30 pieces of plaintext will every be encrypted. And they will be encrypted by legitimate users. So I don't have to worry about people trying to guess the IV before encode. There are no clients of my crypto code that are malicious (and if they were, they'd have brought the company down already, crypto or no). And besides, if you were to break into the code I am securing, you'd just change the system so that the crypto wasn't used instead of trying to game IVs.
I guess on of the most important things is that I'm using crypto for authentication more than message hiding.
As to your last statement, I wasn't speaking of anything but AES128 here. But I think I did use RC5 without an IV for crypto in a previous product. It wasn't broken, it was exploited (bypassed), making all of my efforts moot anyway.
Companies don't advertise as a public service, they do it do make money. In this case, if they can ensure that net neutrality doesn't happen, they can make a mint charging exortion fees to big websites.
It's actually pretty difficult to test something that is 14dBA. Ambient in almost any room is higher than that, even before you put test equipment in the room.
I doubt the reviewers could have managed to test verify the power supply was only 14dBA.
I agree it's pretty clear the reviewers don't really know what they are talking about.
First, you're forgetting the optical drive. As any Xbox 360 owner will tell you, the optical drive can add a lot of noise to the system. On the 360, although the machine isn't nearly silent without the optical drive on, it gets a lot louder with it on.
Also, slow processors and low-end video cards today do not have more than enough power for HD video. They would for MPEG-2 video, but not for MPEG-4 or H.264. Only a very few video cards accelerate MPEG-4 or H.264 at all. And most of them are high-end mosters that have fans.
I have a Mac Mini with a 1.66GHz Core Duo and 2G RAM) and it can't play full screen 1080p H.264 video at full 24fps frame rate (let alone 60fps). It almost can, it'll play it if it is 2.35:1 movie (which means the image is 1920x817x24fps), but it won't play a 1.85:1 movie (1920x1034x24fps) let alone full screen, full temporal resolution (1920x1080x60fps).
What happens if I use predictable IVs in CBC mode?
I just finished up a system where I do use (very) predictable IVs in CBC mode (with AES128).
From what I could tell, an IV really only helps with preventing parallel dictionary attacks. That is, like people use against the UNIX crypt function (in passwd files). Since there won't be more than about 30 things ever encrypted with this key, I figured I didn't need the additional security IV gives me.
And besides, the IV has to be in the code or data somewhere, as it is one of the bits of data needed to decrypt. Most people just store it next to the cyphertext.

So where did this 2-3x boost in efficient come from? And was GE throwing money away when making their more efficient locomotive engines (esp. the new AC ones)?
The article doesn't seem to add up.
Article assumes that many of the seats on a train are empty. But then also assumes that all the seats in a car are full. In fact, it assumes that a car has 5 useable (and full) seats and only weighs 2100lbs.
It baffles me that people write articles like this. Why skew things to prove a point. Make a factual article and find out what the results are as you go along.
They keep stating Apple is pressuring them, but Apple says they have not contacted Apple with any info.
They state they won't say anything until Apple patches the problem? It would speed up the process of getting it patched if they would tell Apple about it!
From what I can tell, they are pretending Apple is pressuring them because it makes them look more important.
Addtional note, what is this stuff about Intel's drivers? Apple doesn't use Intel's chipset, they use an Atheros or Broadcam WiFi chipset. Additionally, what good is getting your packet on the stack? Apple uses the NX bit, so you can't get code on the stack to execute.
I think instead of just using broken crypto and advertising as "uses 128-bit AES for maximum security", I'll instead do that AND insult others. I'll be sure to pass immediate judgement on others and state I know what their plan is without knowing anything about what they're doing.
Then I'll be following the example of you, it seems.
Thanks for the initial help. No thanks for the ivory tower bullshit.
The information in there is all wrong.
I looked up my address. It listed several offenders. One was on a corner. I would go by the house and sort of try to catch a glimpse of the guy. But I never did. Turns out the house was being prepped for sale and it was then sold a couple weeks later.
But if you look up my address, the offender is still listed there.
The database is way out of date becuase sex offenders don't stay in one place long. Very few can get a decent job and so they don't buy houses, they rent houses or apartments. And of course they move around a lot.
Currently, not everyone knows the site is inaccurate, some still believe it. So it does have an effect on property values, even if it wrong. Over time, everyone will wise up and realize that the site is way off and just ignore it.
It always was just a feel-good thing anyway. One thing you can tell just by a quick look is you can't really move away from sex offenders (let alone keep them from moving in near you after you move in) unless you move away from society in general.
Unless your optical drive is riplocked, it will read the disc at 8X or more. Drives are a lot louder at 8X than a standalone drive that runs at 1X.
I have no idea how you say a decent HTPC is defined by where it is playing its content from.
My shitty Intel graphics aren't a bottleneck, they just aren't helping at all. They don't accelerate MPEG-4 or H.264 playback. As to your comments about high-end cards accelerating MPEG-4 and H.264, that wasn't the point. I did allow for this with my comments, but this is a long way from the GP's comment:
"And since relatively slow processors and low-end video cards today have more than enough power for HD video,"
A GeForce 7 is not a low-end card. Nor are the Radeons you speak of.
The GP's argument was wrong about most video cards and misstated how much CPU you need to play HD video. Your arguments do not refute this.
When the BBC posts an article about how this is a safe browser and it appears to be not true (in fact, perhaps it's Adware), then I think the article has risen to a high enough level that a refutal is in order.
Again, the system I'm on is not just a PC in a box. Performance is critical, and I can't use a two-pass system.
I'm sure it's great to have a ton of MIPS available and to be able to choose from many complex modes of operation, but that's not the situation I'm in.
Your judgement of wrong and right assumes you know all the tradeoffs. You don't. Please leave out your uninformed judgements. I just asked from some help on IVs, and as far as I am concerned, I got it. So if you think you can't help me further with the amount of information I am able to give, then I understand.
Let's consider this conversation between me and you over. I ask for help with one thing and instead of get criticism from people who don't know anything about the system I implemented (and I like it that way) insulting me as not even knowing as much as they got from reading a single book.
The useful part of this conversation is clearly ended and I don't see any point in hurling judgements at each other.
I'd like to be funny and say it's because I've used OpenSSL, and I am astounding anyone (including myself) is capable of making a system that works with it, let alone is secure. It's a complete disaster.
But really it's because the system I'm using is an embedded system. And by embedded system I don't mean a full-blown PC running Linux, I mean a small system. I was allocated about 4,000 instructions for my crypto work (and an AES ECB accelerator).
In CTR mode, the each encryption doesn't depend on other data encrypted before it. Thus someone could change a single 128-bit area in the cyphertext and it wouldn't affect anything else. This greatly reduces the difficulty at changing my cyphertext to change the plaintext in certain areas without it being detected after decode.
I appreciate your info, but I think you're jumping to huge conclusions about my system. Again, in my system only about 30 pieces of plaintext will every be encrypted. And they will be encrypted by legitimate users. So I don't have to worry about people trying to guess the IV before encode. There are no clients of my crypto code that are malicious (and if they were, they'd have brought the company down already, crypto or no). And besides, if you were to break into the code I am securing, you'd just change the system so that the crypto wasn't used instead of trying to game IVs.
I guess on of the most important things is that I'm using crypto for authentication more than message hiding.
As to your last statement, I wasn't speaking of anything but AES128 here. But I think I did use RC5 without an IV for crypto in a previous product. It wasn't broken, it was exploited (bypassed), making all of my efforts moot anyway.
"unethical advertisement"
Now that's funny.
Companies don't advertise as a public service, they do it do make money. In this case, if they can ensure that net neutrality doesn't happen, they can make a mint charging exortion fees to big websites.
It's actually pretty difficult to test something that is 14dBA. Ambient in almost any room is higher than that, even before you put test equipment in the room.
I doubt the reviewers could have managed to test verify the power supply was only 14dBA.
I agree it's pretty clear the reviewers don't really know what they are talking about.
First, you're forgetting the optical drive. As any Xbox 360 owner will tell you, the optical drive can add a lot of noise to the system. On the 360, although the machine isn't nearly silent without the optical drive on, it gets a lot louder with it on.
Also, slow processors and low-end video cards today do not have more than enough power for HD video. They would for MPEG-2 video, but not for MPEG-4 or H.264. Only a very few video cards accelerate MPEG-4 or H.264 at all. And most of them are high-end mosters that have fans.
I have a Mac Mini with a 1.66GHz Core Duo and 2G RAM) and it can't play full screen 1080p H.264 video at full 24fps frame rate (let alone 60fps). It almost can, it'll play it if it is 2.35:1 movie (which means the image is 1920x817x24fps), but it won't play a 1.85:1 movie (1920x1034x24fps) let alone full screen, full temporal resolution (1920x1080x60fps).
What happens if I use predictable IVs in CBC mode?
I just finished up a system where I do use (very) predictable IVs in CBC mode (with AES128).
From what I could tell, an IV really only helps with preventing parallel dictionary attacks. That is, like people use against the UNIX crypt function (in passwd files). Since there won't be more than about 30 things ever encrypted with this key, I figured I didn't need the additional security IV gives me.
And besides, the IV has to be in the code or data somewhere, as it is one of the bits of data needed to decrypt. Most people just store it next to the cyphertext.
