[[ Don't drink any caffeine for at least four hours before bedtime ]]
*Sigh* First: this is obvious: if you're very sensitive to caffeine, you'll sleep either less or badly if you drink caffeine before bedtime.
Second: avoid over-generalisations, we're all different: I know some people who wouldn't be able to sleep if they drank coffee before bedtime, me it doesn't do anything to me (even a capucinno and a tea at 23:00).
I'm not sure I understand you: this pdf you linked is against 'node swapping', fair enough, but it advocates still FTTN not FTTH, so it's a different issue..
FTTH seems to me much more expensive than FTTN without much benefit: FTTN + high speed SDSL seems "good enough" to me.

>If Intel are smart they will release a chip containing one core (or 2 cores) from some kind of lower-power Core design and a pile of Larabee cores on the one die along with a memory controler
*Ahem*, what about memory bandwith?? One strong point of GPU is that they have big memory bandwith at a cheap cost as they use a fixed memory setup, if you put both the CPU and the GPU under the same memory controler with replaceable memory then it's quite likely that the GPU will suffer from the lack of memory bandwith.
I heard that Intel acquired some PowerVR IP, probably because tile-based rendering is set to use less memory bandwith than normal rendering, that said PowerVR's videocards were also less powerful than their competition..
>I think the ARM netbooks are going to have a monster market, like eventually over 100 million a year.
Maybe. But Intel with its process technology will be a tough oponent.
>The first generation of netbooks was too expensive for this gigantic potential market, and besides they used too much electricity.
The CPU already use less power than the chipset, so does it make sense focussing on reducing the CPU power consumption? Do chipsets for ARM CPU use less power than those for x86?
And if you really want to focus on low power consumption then you'd need to replace the LCD screen with an OLED screen or an e-ink screen, both technology which are expensive currently..
I disagree: there are plenty of criticisms (though more smart critism as from the Linux hater's blog would be nice), what is unfortunate is the amount of fanboys kneejerk 'answers' instead of just accepting that Linux has some issue.
I remember a 'criticism' I and many had: Linux boots much more slower than BeOS did on much more powerful HW. The fanboys answers: Linux is much better in foo that's why it's takes more time (or don't reboot Linux!). Some times later Arjan van de Ven made Linux boot in 5s(SSD)/10s(HDD) showing that all the previous answer were completely wrong: it's just a lack of optimisation.. Note that the criticism is still valid as Arjan's proof of concept isn't available currently for normal users.
One interesting 'criticism' lately is Chrome: it is really in fact a 'Firefox criticism': Google wanted to have a standard compliant, robust browser and Firefox is the former but not the later so they developed their own solution. When Chrome has a plugin API and is available for Linux and MacOSX, I expect a lot of migration from Firefox to Chrome.
>No language is objectively harder to learn than any other language.
I disagree: in Japan writing is so difficult that there are still studying at grades where in Europe students don't learn anymore reading/writing (as these skills are supposed to be mastered).
[[Not so - having a head-of-state that is not associated with a political party is a great idea. ]]
I'm not sure what's so important about having 'head-of-state', but if you need one on medals, you can choose to print some particular monuments, flags..
Remember that these things can be used as a figure for xenophobia though: in France our 'hymne national' (anthem) lyrics are quite xenophobic (much to my dismay).
[[ Heads of government represent their political party. ]] No, once they're elected, they are supposed to do their job which is to represent the state. Beside in France, at some time we had an elected president from one political party while the government was from another political party, so it's definitedly possible to have a system where the president is just a figure-of-state..
[[ What really need to happen is something similar to what happened to the GIF file format.]]
Given that the GIF format is still more used than the PNG format, I wouldn't use this as a basis for what 'need to happen' more of an example of the *success* of 'submarine patents' (let something patented be used for free for a long time then make users pay): even when there is a better technical solution, it most probably won't be used due to the 'network effect'.
>The monarchy is hardly in the same league as fanatical Christianity.
Depends on which kind of monarchy, but for the current UK one, you're right.
>The monarch does a nice job of promoting British business and keeping the rich and powerful neutralized. Uh? I thought that current British monarch had no power? Well except the one to show that in UK not everybody are equal in principles..

I share this 'belief', well I think that it's more probable.
>Also, I'm a little confused on if your comment is meant as a contrast to the backwards thinking or merely further proof of it.
I just wanted to point out that each group has its own stupid beliefs: for the US it's religions, creationism, and the alien visitors, for the UK monarchy, etc.

[[ How can arguably the world's number 1 science and technology leader simultaneously be so utterly backwards when it comes to teaching science compared to much of the rest of the world? ]]

Yes, that's a big issue with most GC: they interact badly with swap, note that it's possible to make the GC and the kernel's Virtual Memory Manager cooperate to avoid this, see: http://lambda-the-ultimate.org/node/2391
Now, as it only works if the kernel's VMM is patched to support this kind of GC, I wonder if swapping won't be made obsolete by memory's low price before this kind of GC becomes used..
No, POSIX doesn't garantee write before you do a fsync, an added rename doesn't change this.
This situation is identitical to read&write memory ordering: due to a cache, different CPU may see different value of a variable. Different architecture has different limitation on the way to reorganise read and write, with x86 it's not too bad but with the Alpha which can truly reorganise thing a lot it becomes very difficult to put all the needed memory barriers.
IMHO, there is performance / usability tradeoff here, and Ext4 shouldn't reorganise operation too much: it's too difficult to use for application programmers.. If you have 'write then rename' then the write should always be done *before* the rename..
[[ the only architectural feature of Chrome of note is separate processes per tab. But is that a benefit? ]] Yes!! Because it feels more responsive thanks to its use of several process.. Plus when one webpage use too much CPU you can easily find which one does this (using the built in task manager) and avoid this website..
The biggest drawback of Chrome is that you cannot have Flash blocked by default currently. I'm using Opera now (switched during FF2 days as FF2 leaked like crazy), but I'll switch to Chrome when it'll have a Flash blocker.
>They have always sucked under low-light conditions.
Yes! HW makers should really improve this point, for example by using captors such as the one which is 'RGB+transparent', AFAIK this captor is only used in high end (ie big) digital cameras, not compact one.
>They are inherently poor, with their slow zoom lenses, and flash mounted right next to the lens To snap a landscape those doesn't matter.
>Current digital cameras absolutely trounce film for low-light performance
No: I bought my sister a Canon Ixus 860 one year ago for Christmas, her main complaint? It sucks in low light condition (my Sony digital camera sucks too in low light condition)..
Somehow I doubt that they have made much progress lately.
Me as a user, I couldn't care *less* about the Million of pixels since a long time: 5 Million was good enough already.. But low light performance of compact digital camera *suck* currently.
I wish reviewers would test digital camera much more on this point, maybe camera makers would start improving this (very) weak point instead of competing on meaningless pixel number.
[[ But lets back up here, because there's more than just people too lazy to call fsync() in order to ask the file system to write the data to the disk and say "Ok, I got it". ]]
Except that not too long ago there was a row about Firefox's performance because it was using too many fsync..
fsync is a bitch on Linux: don't use it? You may loose data. use-it? As it's syncing not just the file but the whole FS, the performance may suck..
AFAIK, it's not the first browser to have tabbed windows, but yes I agree that Opera is a very good browser.
As soon as Chrome has a plugin to prevent Flash loading, I'll switch though: I like the design which allow to find easily which website is poorly coded and use too much CPU/memory.
The thing is your taste evolve during the time: I used to dislike coffee as too bitter, then I drank coffee with many sugars and now I drink my coffee black (french like coffee as I'm French: I've drank the worst ever coffee in the US).
So I'm drinking now exactly the kind of coffee that I used to dislike: you're not improving based on a fixed reference but on your taste which can evolve.
