Yep I agree. I don't know much about kernel-level memory management, except for the general idea of paging, but consuming ram because its available seems inherently wrong.
If every (non-modal unlike games) app used memory like this, you would have a huge amount of pages swapped to disk at any time. Doesn't considerable increase in page table's size decrease performance for every running app? What about the swapped pages? There is a high probability that at some point in time a lot of them will be swapped back to ram - causing slowdowns. Lots of apps - lots of slowdowns. How is OS supposed to know all that?
I always thought, as an application developer that you should limit your ram use to the minimum required for smooth experience, ie. keep in ram the data that is most frequently used and can be needed at any time. I mean the vital stuff needed for the GUI and the task user is currently performing. I don't know what's changed that suddenly everybody started to forget about this.
Well, I imagine that with web browser things can get complicated. How to know what should be cached? Maybe just keep track of the pages the user revisits most frequently? I know that pages are composed of a lot of media nowadays but heck, does firefox need to keep in RAM images that I viewed few hours ago? I don't see any justification for its current RAM usage.
This level of fine-grained memory management should be done in the application layer. What would be the point of creating a vast API that tries to shift this responsibility to the OS, IMHO it would be just another piece of bloat. That's if somebody did it - right now the OS isn't meant to handle this kind of memory management.
One more thing to make my babble clearer - app can free its memory and OS can't free app's memory, it can only swap. 500GB dedicated swap drives anyone?
And it doesn't prevent me from enjoying it. Are we talking about some scientific paper here or a TV show? I'm into hard SF, and Fringe certainly doesn't fall into this category. But it's one of the best shows out there, IMHO. Sometimes the ideas presented are just plain stupid but this I can stand because its compensated by suspense, great, unique characters, humour and overall story line.
And to you people who comment on something that you don't like just because it does not fit your profile (without stating why it's bad, maybe it isn't, how would you know?) - STFU. If you don't like it don't watch it. But criticizing it saying that it's not pure SF is like saying 'I don't like bannanas cause they're not apples, and I like apples'. It's good in its own genre.
Have you seen the prices in Poland? I could have a gaming rig easily outperforming PS3 in every way for this price. There's no f**ing way they're subsidizing it.
This is been enlightening. I've suffered very similar problems at home, but instead of figuring out the problem I replaced the hardware... After reading TFA all fits perfectly, I had occasional "chokes" - sites would take ages to load, ping's wouldn't return from my Wi-Fi router, DNS queries took ages. All while downloading a big file or something. But what's significant the throughput would stay high. It was strange as hell - high thoughput (an ongoing large transfer [but not large enough to saturate connection]) but other things choke.
Distro's with rolling releases - probably not more than a week or two. I've read somewhere that Ubuntu is considering change to rolling releases model too.

All or any of the above. Seriously, pick a malicious activity that can be accomplished with a PC program and there you have it. Oh, and firewall does not protect you from these kind of explots. It (probably) will make it a little harder to send/receive info to/from the internet by a malicious app but in most cases won't help a lot, depending on how you configured it, how much attention do you pay, etc. Besides there are ways to trick it.
I thought that zero day means that somebody uses it in a attack and it appears that it hasn't been known before the said attack. Public Disclosure automatically disqualifies it as zero-day.
Could somebody explain this to me - if java is so fast and its gui frameworks are so good how come that every bigger application based on this technology feels sluggish and often is simply slow as molasses. Imagine that you write a line of code and it appears on the screen 500-1000ms later (yes, I am talking about a well-known java-based IDE).
I also like to write things from scratch but often I would also like to finish the project I'm working on before the world ends, so this leaves us with Qt. Fine grained abstraction, raster and vector drawing, even wrappers for OpenGL functionalities. Not to mention many helpers. You probably won't see a line of native os api code in your project.
If you want to save yourself a huge amount of time choose Qt. Great, comprehensive docs, dedicated IDE with WYSIWYG GUI designer. There is even a type of canvas that lets you write objects that can react to events and be dragged around while not sacrificing the power of plain raster drawing.

It doesn't. But the less technically inclined users, they can use a clicky interface to configure it.
Get the task being transfered to display a QR code encoding the URI. Simple and foolproof solution.
It makes some sense. Having financial information about someone (e.g. politicians) can be even more helpful than having his offical e-mails.

Such operations need a lot of funding. It's not surprising to see that some legitimate companies decided to provide it...
The summary is probably misleading. Apparently LG claims to have patents which Bluray infringes.
I wasn't talking about yourself in particular. And I didn't mean to be disrespectful.
I disabled my reading comprehension module after "Ballmer says".

So they will just remember to disclose any future hacks anonymously?

My bad, there were rumours and they were apparently wrong.

Or maybe there isn't a paywall but the OP posted a wrong link (through his account).

You don't have to sacrifice server performance - the answer is "pluggable scheduler architecture" which was already proposed but didn't get through.
And maybe the increased sales is the effect of the WOW factor or even simple curiosity for new things...
I thought they built a big dome with an artificial sun on top...
