Actually this is true, I recently covered this in one of my physics courses. Due to tidal friction the moon is currently receding from the earth at a rate of 4cm a year, about the rate of growth of fingernails or the rate at which continents are drifting apart. Due to conservation of angular momentum, this results in a corresponding decrease in rate of rotation of the earth. Days are actually slowly getting longer and longer. In fact, about 100 million years ago, the dinosaurs experienced a 23 hour day.
You can do some rather simple calculations and find that if you put down enough tidal power stations to supply America with all of it's current power needs, the additional tidal friction would DOUBLE the rate of recession of the moon from the earth to 8cm a year. Not really a serious environmental risk, I thought it was interesting though.
"However, the attack presented only applies to a specific network card model (Broadcom NetXtreme) whenever a remote administration functionality (called ASF for Alert Standard Format 2.0) is turned on (it is off by default) and configured. According to vendors, this functionality is far from being widely used. As a consequence, this vulnerability is really likely to have a very limited impact in practice."
One network card by one manufacturer has a vulnerability when an obscure feature is turned on. While the idea of an attack on the network itself is interesting, this isn't going to become a widespread problem.
It almost looks like it's been compiled with winelib, the fonts and buttons resemble wine widgets. It does not integrate at all with GNOME, the fonts are horrible and the interface is clunky.
This is a really hot topic in research right now. For my final year project on my physics degree I am investigating a theory of a model fluid with a repulsive step potential and it's amazing what kind of self assembly you get on a mesoscopic level.
At certain temperatures and pressures the molecules will all just spontaneously line up into stripes or clusters. This could have amazingly useful applications in chip assembly, because you don't need to assemble the chip any more - you just engineer a molecule that assembles itself into the right shape.
The article is awful. There is only one game benchmark and that compared to an integrated AMD GPU that hardly anybody has heard of. There is also no way of telling from the article whether the integrated intel graphics actually has HD video decode acceleration or not. The modern core i5 chips are pretty capable of decoding 1080p content by themselves without any gpu assistance.
I think the article writer misunderstands how hardware video decode assist actually works. It isn't magically engaged when you play any HD movie in any media player (usually it has to be turned on in an option somewhere with a media player app that supports it) and it isn't a sliding scale of cpu usage. Modern decoding chips either decode EVERYTHING on the card, reducing cpu usage to 1% or 2%, or the app decodes EVERYTHING in software, resulting in fairly high cpu usage.
I still have no idea if the new intel graphics chip actually offers any HD video acceleration at all. If it did, it would make it a nice choice for low power and HTPC solutions. If it doesn't, it's just another crappy integrated graphics card.
Most clients use encryption by default, but will accept plaintext incoming connections yes. It's fairly easy to configure your torrent client to only allow encrypted connections if you are feeling paranoid.
Deep packet inspection does not extend to joining swarms with a modified client. At least I'd hope not...
This won't work, most modern bittorrent clients use encryption by default now anyway.
Shame they don't just save the money and spend it on upgrading their infrastructure instead...
I'm very surprised this was an exposed option before Karmic, you must have had one of the very rare sound cards with a hardware loopback in it or something similar.
Either way, pulseaudio has this functionality now. It isn't exposed in a gui option, but pactl load-module module-loopback will do what you want. If you want it to load every time put it in/etc/pulse/default.pa.
I know this sucks compared to having a gui option, but hopefully a gui option will be added for this in the next release. You can probably still enable your hardware loopback if you have one by running alsamixer -c X where X is your card number, probably 0 if you only have one card. You can find out what cards you have with aplay -l.
I know cli utilities suck but trust me, this is being worked on even if the work is going very slowly.
I've been using Ubuntu since 5.04 and tried an upgrade every time a new version came out. I have never ONCE had one actually work, so I always ended up reformatting/reinstalling from scratch.
This is the first time an upgrade has gone smoothly for me. The only thing that went wrong was firefox failed to load my session directory, and this is only due to upgrading from 3.0 to 3.5. In fact, firefox 3.0 was still installed on my system and that worked perfectly still.
In general however, the Ubuntu upgrades always seem to be a bit flaky, far better to separately partition your home directory and reformat/reinstall instead - too much fundamental architecture changes with each release to make upgrades really work very well. You still keep all your application configurations and data easily that way as well.
Sadly this lack of support probably just means that no USB3 devices or chipsets will actually be produced until the next version of windows comes out that DOES support it.
I've compiled kernels before but I haven't patched them. It doesn't look too hard, except that it doesn't seem to say anywhere which kernel version to apply the patch to. Latest git? Latest stable? Mainline? Any ideas?
Why are they using an ATI card? Nvidia cards have much better support under linux generally, including full 1080p h264, mpeg2 and wmv hardware decode support. ATI don't have any hardware video decoding support at all, so to play HD films you need a much more beefy cpu creating a lot more heat and noise than with the nvidia solution.
ATI's drivers still haven't really got much better, tried installing them on a friend's Ubuntu pc the other day for a radeon 3650. Trying to enable compiz caused the entire system to hang immediately, and the only way to get working video was to use the opengl output option. The open source drivers aren't exactly brilliant at the moment either. If you want real opengl or video support on linux your only option is still nvidia.
Now THIS sounds like a reasonable suggestion. This friend is pretty much funded entirely by his parents, I think when he get's his exam results back and they all show Fs then maybe something might happen there. I hope so, otherwise it will just be another summer wasted on an mmo...
I'm the OP. We already have a linux pc as a router - I set it up, so the internet has become essentially my responsibility. One time it had an IRQ problem where it would drop connections every few hours or so - my friend went MENTAL and raged on at me about the shitty internet and how shit my router and I better fucking get it fixed ASAP.
If I started randomly dropping connections or otherwise interfering with the game, he'd blame me and have a go at me until it was fixed. So that's not an option:-(.
I'm the OP, it really isn't an advert I promise! I really do have a friend that's addicted to this shit - I wouldn't recommend it to anyone after what it has done to him.
In summary, it seems like a fairly useless and poorly thought out format. To be clear, this WILL NOT play losslessly in a standard mp3 player, you must use a special decoder to get the lossless bit. It will only play the lossy component in a normal mp3 player.
Lossless information stored in id3v2 tags? Bad hack that will break just about every tagging program out there. File sizes much larger than real lossless codecs and encoding/decoding speed is much slower than flac. Also you can't have tracks longer than about an hour due to id3v2 size limits. Additionally, a full size flac file and 256kbit mp3 often comes in at a SMALLER size than this one monolithic hacked up mp3.
Nothing to see here people, this is a waste of time. Something like lossy/lossless wavpack hybrid is a much better solution.
Virtualbox doesn't just give VMware a run for it's money, it's considerably superior in many respects:
- It's open source - The gtk interface is at least as good as vmware's gui - It's considerably faster on my system (no hardware virtualisation), windows xp boots in about half the time in virtualbox than in vmware, and applications generally open/run much more snappily. - It's considerably more stable (on linux) than vmware is. In my experience vmware crashed about 30% of the times I used it, I even got a total system crash once that needed a hard reset (I think due to problems with compiz?). It uses quite an intrusive kernel module that creates a lot of latency in the kernel. This manifests itself mostly as skipping audio when audio is playing. Virtualbox has none of these problems, it's rock solid stable and doesn't hog the cpu like vmware does. - Virtualbox seems to need less ram than vmware, I only have 1GB of ram in my laptop and swapping was unbearable with firefox and vmware open, yet firefox, virtualbox AND other applications can coexist fine with only limited swapping.
That's all the advantages I can think of of the top of my head, the only disadvantage I can see is that vmware supports USB devices whereas the free version of virtualbox doesn't. Other than that, virtualbox is just better all round.

Use latex. This is what it's for.
Alternatively you could just get Be Unlimited, which gives you up to 24mb/s and NO CAP for £18 a month. Why anybody uses anything else I have no idea.
