No they're not. That's only true if you run them off DC.
This article is all about replacing light bulbs - and normal light bulbs run of AC, so LEDs will flicker just as much as florescent lighting. They're also diodes, which theoretically means that they would normally flicker twice as much. However I think they put two sets of LEDs in to counteract that effect and probably some voltage smoothing capacitors.
What do you think "archive" folders in Outlook are for? Emails older than 100 years?
Many companies archive financial records, which are then permanently destroyed after 5 or 10 years. There is very little you'd want to archive for much longer than this in the business world. Archived data is simply anything you don't foresee needing to use again. Even if you last used it last week - you might as well archive it if you know you're probably not going to need it again.
I've got no idea why you're comparing archiving data to human memory. No human can remember every single byte of every backed up file on their PC for even one minute - let alone 100 years. I assume that bit is simply flamebait as it's a ridiculously stupid comparison.
Because currently an SSD will not last the life of your computer. At some stage prior to your processor wearing out, the disk will fail and you will lose data. At the moment, a mechanical HDD is still less likely to fail than an SSD.
We use them here at work in firewall applicances and I've so far yet to see an SSD last for longer than one year when the disk is used heavily to log network traffic. SSDs are absolutely rubbish for high usage (high read/write cycles). If you made one into a Usenet server for example, I doubt it would last a month.
Long life SSDs would also make the ultimate backup medium.

Review of Das Keyboard

· Score: 2, Informative
No problems with a washing membrane keyboard if you take the membrane out:) I've successfully dishwashed a Microsoft Natural keyboard and it came out like new. It took less than two minutes to remove the membrane and PCB - everything else went in and was left to dry in the airing cupboard for 24 hours before reassembly.
I don't see why any of what you said is relevant as this software only works on WiFi and NOT on 3G connections?? Have you actually read the article?
From TFA: "It promises seamless call switching between VoIP via WiFi and regular calls. " and "Apple has explicitly stated that VoIP is allowed, just not over Edge networks"
I'm not sure therefore, why you've been modded as insightful when your post is totally wrong - unless I'm missing something??
Don't know where you read that, but it's wrong. There is no "blocking" and no apps need to user input to simply "run".
A video encoder for example, will continue to encode video at 100% CPU, even if you switch users. No blocking, swapping, pausing, suspending etc happens just because you've switched users. The only thing that happens is that the app gets visually hidden from the new user in that it's not on their screen or task bar.
> "Fast User Switching"): User pauses session; apps are unloaded to swap file. Other user logs in; apps are reloaded.
Er no - that's not how it works at all (not if you're talking about the one built into XP and Vista anyway). Nothing is 'paused' - the applications for both users are running normally the whole time and nothing is specifically swapped to disk. Swapping users only changes your desktop settings and which applications appear in the task bar (ie which ones YOU started, as opposed to the other logged in users).
Yes I realise you put humans on as a payload, but theoretically you could do that with an Ariane rocket. The interesting bit therefore, is not the Falcon rocket but the Dragon payload. Even though it's cheaper, I would expect that the cost of launching the Falcon *massively* exceeds the cost of a flight in SpaceShipTwo?
SpaceShipTwo is also closer to people's dream of just going to a normal airport to take a trip into space. You don't really need a dedicated Cape Canaveral style space port for SpaceShipTwo - you just need ANY runway that's long enough. Thats a big selling point and will also help to keep the launch costs down. The concept of SpaceShipTwo/Three/Four is always going to excite ME far more than something that looks like a 1950's rocket.
They're hardly comparable are they! Slashdot readers are far more interested in something which will take PEOPLE into space, rather than yet another satellite lifter that's only interesting because it's cheaper to make.
Apart from anything, SpaceShipOne/Two just simply looks WAY cooler! I know that's not a very good reason, but it probably IS a reason.
I think most people are interested in feeling like they're going into space, zero-G, black sky, take some pics, then coming back again safely. You don't need an orbital vehicle for ANY of those things.
Falcon 9 is about as exciting as a Toyota Prius - only interesting if you're the one that's going to be saving the money.
Why does Firefox 3 seem to ship with the back and forward buttons turned off?
I doubt very many people know the keyboard shortcuts for these (and even if the do KNOW them, it's unlikely most people actually use them very often (and yes I know SOME people use keyboard shortcuts so please don't post saying you use them because I don't care)).
Your point makes perfect sense so long as your browser is the ONLY application you run! Imagine if EVERY application munched RAM as much as firefox...
I think the point that people are annoyed about is that there are other fast browsers out there which DON'T eat all your RAM, so why does firefox need to?
Regarding your last sentence - yes, it would be nice if programs would all try and use RAM if there's loads free, but free it up again as soon as anything else needed it... For that you'd need some kind of "low priority" indicator when you reserved that RAM - indicating it's only a cache of something and should be paged out first if it's needed by another app.
Out of interest, why does anybody need 35 tabs open? (not mocking - it's a serious question... I'd personally find it difficult to work like that). It sounds to me like some people seem to use tabs how I use bookmarks.
Nope... usually before it's released, they remove the "RC" designation from the name of the browser (about box etc). They almost never simply just release the actual release candidate binary. Therefore the binaries will be different. Sometimes the version number changes too... eg 1.98 RC4 might become 2.00.
Is it me, or does Firefox 3 not keep your old cookies and passwords etc? I seem to have to relogin to every website.
Memory handling doesn't seem to be much better - it's up to 220Mb already and I've only been using it 10 minutes. It's definitely faster though! The javascript engine seems WAY quicker on my own sites at least.
How do you know for sure though? Until the actual download link is revealed by mozilla, the previously posted link could be incorrect. The real setup file might be in a different folder.
That one post has probably trashed their attempt to break the record for most downloads in one day. Now, everyone on slashdot will have downloaded it before the official 24 hour download period even starts.
> a simple watch battery could power the chip for more than 200 years
Rubbish! Even if you draw ZERO power from a watch battery, it will be totally flat in less than a tenth of this time. They have a 15-20 year shelf life and obviously that will only get worse if you put it in a device that draws power from it. You would need at least 10 batteries to power the device for 200 years.
Yeah but it would only take a minor upgrade for the machine to be able to print a copy of itself which is BETTER than itself. Once it's done that, the machine can become infinitely powerful with no human intervention:)
I think you're missing the point. 99.9% of people on here would not WANT to port it even if they really WANT or NEED the resulting ported solution. Why the hell would I spend weeks learning a different branch of programming just to get some network card driver? I have a life and other things I need to do. It's easier just to switch platforms, dual boot, find an alternative etc. Pretty much ANY alternative solution is probably better for me than trying to learn how to write that code and port it myself. The same is probably true for nearly everybody else.
I hate it when people say "just port it" just because something is open source - Like every single computer user is capable of writing low level network code for any platform. I suspect that more than 99.9% of people of people who read slashdot would not stand a hope in hell of "porting it".

So Windows 7 better not get delayed.

I can only see that it would be funny if everyone's misreading it so that they THINK it says "It comes with Vista, which is a free download".

Why does that get modded +5 funny?
So far all windows service packs have been a free download. I really don't get why that's at all funny.
