"The OS will only use memory for cache when there is no other demand for that memory"

Ok, I'm not going to bother and read the smart people. I'm going to go straight to my point.

If you are using nearly all available RAM for disk cache, then EVERY REQUEST FOR RAM WILL REQUIRE CACHE DUMP.

It's like this;

If you have 4GB RAM and are using, say, 1.5GB for applications and system, and you use 2.2GB RAM for cache, then you are left with 300MB approx for any new demand. So any demand in excess is going to make your system dump cache, and it does take time. How much is an interesting discussion. And yes, we can consider if the request is going to be satisfied out of cache, but let's also assume if it is than that cache will not be dumped. That would be unfortunate.

Here's my beef with this much more aggressive caching in 7 v XP:

What the ^&)$ do you need 2.5G cache for?

What are the likely demands on caching? Office 2007? My XP machine at work rarely shows Office 07 components using more than 500MB RAM. 2G caching? Pagefile getting you down, you don't want to use that?

More to the point, how often would a real-world user be USING 2GB RAM, much less 4GB?

Well, I do. But real-world? I have 2-4 virtual machines running fairly often, and in XP I rarely get up to 3GB. Win7 would maybe get me into 4GB+, sure, and the pagefile would go crazy.

When Smartdrive first came out, we used to tune it down quite a bit to avoid hogging RAM. I know it's improved, and I've never worried about it since Win98, but the more I read about Win7's caching, the more I think it is there for some strategy here that has nothing to do with user demands, and everything to do with OS performance. Vista and 7 both cannot be descirbed as lightweight, so maybe this is really to keep the OS light on its feet.

Fine. But MS can't say so.

Another resource hog. Hopefully it won't hog anything we need, right?

I just don't get it. Obviously.

Users have the mindset that file formats are proprietary and belong to specific programs.

How about:

Users have the mindset that their documents are somehow stored "inside" the program. Consider a conversation I had recently about a customer that needed a newer office suite, but didn't like the Office 2K7 ribbon:

Me: Ok...so we'll uninstall Office 97, and install OpenOffice instead. It's free.
Them: But all my documents are in Word.
Me: Yes. OpenOffice will handle them just fine.
Them: But all my documents are stored in Word. If you take Word off my computer, how will I get my documents?
Me: Just use the File->Open menu in OpenOffice, and load the file.
Them: [blank stare]
Me: The documents are still on your computer, you'll just load them in a different program.
Them: But...[weakly]..all my documents are in Word.

They honestly thought that Word was somehow this black box thing that "contained" all their documents, and gave them the ability to edit them at the same time. They were absolutely convinced that removing Word from their computer would take all their documents with it.

It serves no purpose but to try and get more money out of my wallet.

I don't know about you, but I only buy something if its probable value to me is greater than its price. If they're getting more money out of my wallet, that probably means I'm getting more value. There's nothing wrong with that.

What's so evil about targeted advertising? It's win-win if you make rational decisions. Yeah, it sucks for someone who buys anything that's shiny, but what else is new?

No, "everyone" is look at the CURRENT 3G coverage map. NOT the ones from 6 months ago. Hell, there's a whole TWO cities in my state (one being the one I live in, but not the even bigger one just 10 miles away, where I often work) that is on their 3G coverage map. If you don't believe me, check their site. Don't look at the green map - the one that does have a lot of coverage, that's just voice. You have to click "data" and look at the purple map - THAT is the data coverage map and the dark purple (which is in the minority by far, even now) is the 3G coverage. Compare that to Verizon or AT&T's 3G coverage maps. T-Mobile has done a lot to improve 3G coverage in the last 6 months, but they're still a LONG way behind the competition.

Maybe T-Mobile has 3G coverage not shown on their coverage maps - if they do, great! But if that's the case, then they need to update their maps or they'll keep having people go to Verizon or AT&T due to their own coverage maps showing them to not have much in the way of 3G.

Submission + - Inside France's secret war (independent.co.uk) 1

MT writes: "For 40 years, the French government has been fighting a secret war in Africa, hidden not only from its people, but from the world. It has led the French to slaughter democrats, install dictator after dictator — and to fund and fuel the most vicious genocide since the Nazis. Today, this war is so violent that thousands are fleeing across the border from the Central African Republic into Darfur — seeking sanctuary in the world's most notorious killing fields."

Submission + - China blocking RSS feeds (arstechnica.com)

Phurge writes: Savvy Internet fans in the people's republic have known for a long time, however, that there have been simple ways to get forbidden information. One of those ways was the magical gift of Real Simple Syndication, or RSS. The Great Firewall can block specific web sites all it wants, but as long as there's an RSS feed, many Chinese surfers can use feeds to access otherwise forbidden information. Unfortunately, China appears to have finally gotten wise to RSS as of late — reports have been popping up from our readers and around the web of not being able to access FeedBurner RSS feeds as early as August of this year. More recent reports tell us that the PSB appears to have extended this block to all incoming URLs that begin with "feeds," "rss," and "blog," thus rendering the RSS feeds from many sites — including ones that aren't blocked in China, such as Ars Technica — useless.

Submission + - Two iPhone Class-Action Cases Emerge

An anonymous reader writes: Two new class-action cases against Apple are taking shape. The first involve the widely reported suit by Queens, NY woman Dongmei Li over the $200 iPhone price cut. Li's lawyer Jean Wang tells InfoWeek she's seeking to broaden the case. "I'm looking for a class action," Wang said. "Right now, I'm seeking as plaintiffs people just like Li, who feel their property was devalued. We're suing them not for lowering their prices, but for the various anti-trust violations that have resulted from them lowering their prices." The second case comes from California lawyer Damian Fernandez, who's looking for plaintiffs to join an iPhone warranty suit over iPhones that were "disabled, malfunctioned, or you had third-party applications erased after you downloaded iPhone update 1.1.1"
