That's bullshit, the core2 is a different design, not just larger cache when compared to the core. First, the core is a pentium M, which iirc has 2 pipes for ALU, one of which does load/store as well. The core2 has 3 pipes for ALU and dedicated pipes for load/store.
The core2 is faster because fundamentally the IPC of the core is a lot higher on average. The larger cache does help but the benefits decay exponentially. So from the 1MB and 2MB parts to the 4MB part the benefits are not as high as you'd think.
There aren't a lot of applications which can truly take advantage of 64-bit integer registers. In fact, bignum math is about the only that really comes to mind.
What does matter is the address space. It isn't even the memory [as in physical memory], but virtual address space. As more and more mapped memory is used by applications like databases, it is nice to be able to just logically access it via a mmap.
For example, you can mmap a 10GB file to memory, then poke at it like you would a C array, even though you may only have 512MB in the system. That's something you just can't do in a 32-bit process even if you had the memory.
stopped reading once I hit the word "solution." it's a fucking product, or project. Not a solution. Solution is like x = 7, that's a solution. Some software does something is a product. Because frankly it's not really "solving" the problem, it's just addressing it. If it "solved" the problem it would work on any platform, any browser, etc...
Also who gives a flying shit anyways? There is more to this Internet thingy than watching annoying adverts that people splash on pages and/or youtube quality shitacular craptastically bad home videos.
I like the way you explain the situation. I think if more laypersons thought of it that way they might not buy into the hype of things like HDCP "enabled" TVs and monitors [etc]. Usually I explain it as "they want to control what you can do with your own machine" but people think I'm making it up or being alarmist...
"defective by design" certainly is a catchy saying too;-)
They probably spend more on licensing DRM and other nonsense than they lose to copyright infringement anyways.
Fundamentally the problem is the execs are [or have been] absolutely convinced that DRM is not only the solution to the problem, but that the customers actually don't mind the problems it creates. I don't know how in this day and age people still propose and want to develop DRM "solutions," as it seems like more and more laypersons are becoming aware of just how detrimental and annoying it can be.
As for never buying a sony DVD, well I'm sure the others aren't peachy clean to. What I'd do is just rent the movies, if they don't play ask for a refund on the rental. If the movie both plays and is super neato fantastic, then and only then, buy a copy. So far 99% of all recent movies fail to meet the "I'd like to see this once, let alone twice" test.
As the victim of joe-jobs, yes, people *are* that quick to judge. Trust me.
And often, joe-jobs will stick your personal info (phone number, address, email addy) on the attacks. Sure, you or I may be able to tell a forgery easily, but there are enough people who are not as knowledgeable or quick thinking to figure it out.
First, no shit. I'd have already tried renewing by time I get there. When I call them and say "I can't renew my DHCP lease" telling me to "run ipconfig/renew" is just ignorant not helpful. That they tell me to run windows specific tools instead of using the more generic "please try to renew your dhcp lease" says they're reading a script which means they're unlikely to help me in a timely fashion.
That'd be like going to a mechanic saying "my brakes aren't working" and having them say "have you tried pushing the brake pedal?"
That's my point though. They should investigate the problem instead of annoying the fuck out of the customer. If I tell them I can't ping the gateway, or DNS isn't resolving or whatever, chances are I have half a clue. Telling me to run "ipconfig/renew" on my non-existent windows PC (which they *assume* I have) is annoying and unproductive.
The truth of the matter is most L1 support folk are retarded script monkeys who know about as much about computers as they do about open heart surgery (that is to say nothing). They're annoying because they're *incapable* of diagnosing a problem and it always takes 10 minutes of convincing to get higher up in the chain.
Now granted my modem rarely goes down, and usually I'll let it sit for 10 mins before calling it in. But every time I have to talk to them, I swear, it's the worse day of my life.
I remember my goplay account which was after i had an account on tattle net and was a regular on fidonet, transcanada, tattle and a few other mail exchanges.
Sadly things like UUCP and what not were before my time, but at least I wasn't naive enough as a kid to think we had invented networked computing.
Raise your hand if you remember a time before cell phones were ubiquitous.:-)
I think you give them too much credit. More often than not when I mention something like "I can't renew my DHCP lease" they think I'm speaking in tongues. Then ask me to reboot the modem (which I do anyways, cuz they do overheat an all), repeatedly, plug it directly into a Windows PC, etc..
Sometimes, the problem *REALLY* is on their end, and if they had an ounce of respect for customers who actually know a thing or two about computers things would go a lot smoother.
I'd rather be told "the gateway for your subnet is down, it should be up in 15 mins." Then be told I'm an idiot and need to reboot my non-existent windows PC. Sure I'm probably in the 1% demographic of their customers, but that doesn't mean they have to be assholes about it. Once you realize the customer has a clue, stop treating them like an idiot and get down to real work.
Point is you have to evaluate every situation. Not every customer is an idiot or trying to rip off the company. Being treated that way just makes things harder to resolve and costs more money anyways.
Ahhh good ol mutually assured destruction. A scheme that has worked so well in the past...
Maybe the right solution to this problem is to actually have innovative products of a useful nature. If some jackass can rip off your idea trivially, then it's not really worth that much is it? If what you make takes craft and skill, it won't be trivial to knock off and you'll be able to compete in the market place.
If you actually think about it, patents are anti-capitalistic because it denies people the ability to compete on the merits of the product.
That's an interesting theory, but if the patent were so easy to invalidate, couldn't RIMs competitors do it as well? Thus making the 650M payout redundant and a complete loss.
Truth be told, even though you or I know the patent is obvious, chances of actually overturning it without a hugely costly legal battle (that even RIM didn't want to play) is low.
Um while I agree that people will tend to minimalize their responsibility for something going awry, I've had hardware and software that just plain didn't work out of the box.
The problem i have with most tech supports is that they often know less about the product than you do. ISPs and telcos are good examples. "please plug the modem directly into your windows PC..." etc is bullshit when the modem is just a standard cable modem that does DHCP over ethernet, etc. But they try the "scripts" on folk and assume you're doing it all wrong. So far every time my modem went down, I've been told that it was an error on my end, when I ask them to press the issue they say something about a "planned outage." Which they might just say to make me shut up, but the modem always magically comes back up without me doing anything on my end.
Where I've had good luck with RMAs is Tigerdirect. Everything I've bought from there was a lemon (two mp3 players and a SO-DIMM for my laptop). All of them failed spectacularly out of the box. All of them they accepted back for a refund. I've never bought from them since though as it's not worth the hassle.
Sometimes I guess they just know they sell shit and it's best not to get negative attention by causing a scene.
What about the folks using packet BBSes in the 80s? Surely that's wireless email:-)
I think a large problem with patents is that society as a whole doesn't remember anything past 5 years ago. Kids honestly think that "hotmail" for instance, was the first e-mail provider or most significant, (mostly because they're so young that the oldest computer they touched was a P4 in 2000 or whatever).
That being said I hate crackberries so I'm kinda for RIM getting screwed.
WINE is not an emulator. It runs the 32-bit apps natively and just translates syscalls (and other dll linkages). So it can't run 16-bit apps because Linux doesn't support running 16-bit apps.
But if you really really really want a 16-bit environment grab yourself qemu or vmware, put freedos in it, then win 3 or whatever on top.
I think it's very suspect. That movie played on both my friends and my Sony DVD player [don't know the model, but it ain't the 500-in-1 changer obviously]. It also played on my "Kaco" brand 30$ DVD player. It's entirely possible though that there are multiple runs of the DVD with different copy protections on them though.
Either way, the movie sucks anyways, that it doesn't play isn't really that detrimental. That they found a new low in the DRM world is though.
I especially love the "piracy is theft" anti-download nag at the beginning of the DVD. Oddly enough it's not part of the movie stream, so had you actually ripped the DVD, you'd never had seen it. Only legit paying customers are nagged to not not buy DVDs. And this is why I hunt and pick DVDs from amazon.com instead of buying the latest "blockbuster" that the studios tell me to (proud to have recently bought Tigerland hehehehehe).
Did I also mention that Casino Royale sucks? Cuz it does. Smacks of gaydom and product placement the likes of which only American Idol could top.
I dunno about you but I can type on QWERTY (touch type) much faster than I can design or debug software anyways. So the bottleneck is rarely "oh my slow fingers type faster!! if only I could write 100 lines of code a minute instead of half dozen or so!!!!"
Unless you're some sort of.NET reject who just codes and codes all day without thinking it doesn't matter.
It's like bragging you have a quad-opteron workstation for text editing. At some point, excess performance just doesn't matter.
As a relatively new driver (less than a year) on Canadian roads during the winter. I have to call you an asshat.
I've driven through a good 10 inches of slush before, and you know what I did? Reduced my speed. Instead of 80km/h I did 30-40km/h and sometimes slower. You can feel when the car isn't gripping well, that is unless you're driving a poorly tuned tank of some sort.
Unless you hit a covered piece of ice, it's really hard to argue you couldn't have prevented the argument, and in general, you'll know when there is ice because it's freezing rain outside. The real question is "where" the ice is. But in any event in freezing rain you shouldn't really be driving but if you have it's just a safe bet to reduce speeds considerably.
As for not stopping for lights, try this trick, look for a pedestrian crossing signal [if any]. They'll give you more than advance warning. If it's flashing the don't walk sign expect the green to turn yellow shortly, in which case if you're really far away, expect to stop and slow down accordingly.
I don't get why people rush to speed to red lights. For example, my trip to work is pretty much along one road that has a half dozen lights on it. And between every single light people feel the need to hit the speed limit + 20km/h, even though there is only 1km between them. Newsflash: That's how you wear out your breaks and engine quicker. Usually I hit at most the speed limit (only if the light is green) and usually 10 under if it's yellow or red. No sense burning extra fuel to wait longer at a light.
And having practical knowledge to know whether your design pays off or not is probably a good idea too n'est pas?
Sure you may know how to implement, say an efficient matrix reduction algorithm. But the devil is in the details. Try implementing that on say an 8051 or FPU less machine, etc...
Having practical experience allows you to make *rational* design decisions that are likely to be lower risk than someone who has no experience writing software.
My brothers wife is doing a masters in biology and she spends considerable time in the lab doing non book related work. My friends wife did a masters in geology (underground water studies) and spent considerable time in the field doing survey work.
etc.
Many sciences have a practical observation/doing side to them. Even physics. It's just plain foolishness to think you're above getting your hands dirty because you're in university. While, yes I agree that CS degrees tend to stray towards the practical side too much, that hardly means there should be no practical side at all. Probably the only one I can't see having a practical side is mathematics. But even then the gold is in the application of the math not the math in and of itself.
Imagine a world where your ideas held true. Doctors would drop into the hospital having never touched a human body. Engineers would have never built a model or performed observations, etc, etc.
Anyways, to get back on topic, if you think going through uni with zero practical experience is the best way to achieve your goals, all the power to you. You're either a trust fund baby, or just have no idea how the real world works. If the OP wants to get the best mileage of their CS degree they best develop their portfolio. It's that damn simple.
I think the solution then is to not offer what you types call a "pure" comp.sci degree. Because no other science is purely book work.
Computer science is a tool that allows you to sensibly design software. Just like architecture allows you to make sensible home renovation decisions. Or how a medical degree allows you to know how to physically treat a patient. If you just want a book education, save yourself the trouble. Get a membership at a library and read the books. Save yourself the expense.
At anyrate, even if you do a few practical courses amongst all of the theory, you're still hard to pick out from the 1000s of others in the same boat. Which is why practical experience like your own successful OSS project is a handy thing to have on a C.V.

Unless a competitor grows outside the US market. Believe it or not there are plenty of mobile users in Europe and, last I heard, even Asia!
