I made some nice animations of the way the some sites have changed their layout (google, ask and altavista). Both altavista and ask are turning more and more google like.
It seems a simple idea. You show which stories were rejected on some page in tha back of the site. It allows the people to view for themselves the story whores and it lets people starved of news to see some 'weaker' stories. The only problem I see is people writing nonsense storys/flames just to get the visibility but that has always existed in the comment system anyway.
I used winace to do the compression. The idea is to determine which format to distribute the files in and ace is still possible due to the linux decompressor.
For these I chose the highest compression for each test. I chose to do that because most of the compressors assume the max compression option (e.g. bzip2 assumes -9) and I was more intrested in the size reather than the speed.
rzip and szip are the two compressors which I didnt know about before I started doing the review. They are both about a couple precent better than bzip2 and I will include them if I do an update.
I think you misunderstood. The attack was not at the lack of public transport (I have been in many cities in the US and there is adequate public transport for me to never find the need to get taxis etc). It was an attack at the culture of fixing any situation with the purchase of material possessions rather than changing ones behaviour. Wife is angry => Buy her some diamonds Children are screaming => Buy them McDonalds The environment is collapsing => Buy a car
Here in Europe the fuel prices are vastly different. Where in the US the price this year was between 37.9 and 26.82 UK pence / litre, in the UK it is currently 91 . So you would have to multiply the savings in petrol by 3 or so. Fortunately in Europe we also have a system of public transport which most environment minded people (like myself) prefer to use rather than pretend we are doing our bit through the purchase of a new car.
These really aren't very good but hopefully people will send some better ones in. My personal ones:
A friend in the office had to install identical 2 machines with linux. Step 1: Install linux on one machine. Step 2: Install the hard drive from other machine into the computer. Step 3: 'dd' one disk over to the other one. Step 4: Scream as you did it the wrong way round and overwrote your newly installed disk with blank disk garbage.
On a server I needed to remotely manually replace libc with an older version file from another machine. Ofcause you have to remember to do everything in a single command otherwise if you delete the old version you cannot run anything else. (I am sure there must be a simpler solution to that than take the disk out and do it on another machine)
Leaving a computer under the desk but pushing it back as far as it would go so the back board of the desks fully covered the fan hole. It got very hot after a day and then burned out the cpu and powersupply in one go.
Inserting a K6-3 into an older board which I didnt want to replace. The board had jumpers with markings for the CPU voltages 3.1, 3.0, 2.9, 2.8, 2.7 and followed by 2 unlabelled jumpers. The chip wanted 2.6v core supply (I cant remember the details) so foolishly I assumed the other two jumpers were the lower voltages for which there were no processors at that time. I was wrong and a puff of smoke appeared as my lovely new 450MHz executed its first and only operation.
Checking if the IDE cable worked itself loose without moving the computer from its place and leaving it turned on. So I am reaching round the side and blindly feeling around for the cable and I suddenly feel something like an electric shock (which turned out just be accidentally touching the cpu fan blades). I very quickly remove my hand snagging it on one of the many sharp pieces of metal sticking out of old cases. It was quite cool to be able to see my muscles moving around as a huge piece of skin flopped open exposing the tendons in my hands.
Yeah it does very much so. This doesnt sound as extreme as niagra and still should keep reasonable performance unlike niagra with single issue no speculation.
These break down to a few different kinds: Information leaking e.g. power analysis: observe the power consumption of a divide to determine what operations it is executing and what data it is working on. Usually these will only tell you the number of bits which are on in a particular stage. I found the ARM 6 gave a very clear signature of the result of the adder and could determine the number of on bits down to the nearest 2. Error introduction e.g. clock glitch attack: This is an asynchronous engineers favorite. Basically a method of inserting errors into the processor in a deterministic method. Say the processor stage calculating a compare operation is the worst case path, the attack inserts an early clock forcing the comparison to be incorrectly made. Place this in the "are the checksums correct" code. Usually though these are a little more difficult than that. Brute force with limited tries e.g. Flash charge pump: So to crack your card it only takes as many attempts as there are pin code combinations. To stop people from just trying out the 10,000 or so combinations the card remembers how many tries you had. Before it writes something to the flash it needs to drive up a charge pump. This is visible using power analysis and at this point you cut the power and try again.
More interestingly why are these not investigated? Well because there is no money for it. The async community has been offering better methods but the companies who make the only get a tiny profit are not inclined to make them any better.
"a distributed method for distributing content" Reminds me of the Fast Show quote: "The mafia is probably the most organised of the organised crime organisations"
People always talk about the end to Moors law stating that we cannot solve some challenges. Other people always reply "well we always manged to solve challenges and we probably always will". What I think is more interesting is how far ahead we can solve them. The clock distribution problem was a problem for seen and solved years ahead of it biting hard. Nowadays the problems arise and we have shorter and shorter time to react before they cause serious problems. This is the strongest proof I found that this technology will (eventually) stagnate.
I think it's great to have a few quickies rather than one full thing (no phun intended). It is much nicer to browse through 20 little interesting and concise nit bits than one big story.
That is the addressable memory space. Curiousley the x84 instruction set doesn't have a 32bit (4Gb) wall but reather an 64Gb wall due to the segment offset. This is the original hack which gave us 1Mb limit reather than the 64K. The only reason linux gives you the choice between the two when compiling is to allow the address to be stores in one 32bit int.
I was just looking at the google cache of that page and there are loads more instances (including the 2029). Do they remove the ones too unlikely to happen once they get better measurements? (Or insert conspiracy theory here)
That is the cumulative impact probability. The probability of impact in 2037 is actually 1 in 526,316,000 chance. The more likely one is in 2044 and that is 1 in 83,000 chance.
I have seen this idea for ages and seen many implementations (inc. my own) but I still dont understand why people bother. Last thing I need is something stitting on my desk distracting me. Its not as if paper pictures are that inconvenient and sure when you may want to remind your self of what your wife looks like before returing to the wrong home (again) but you have a great big 19 inch screen to look at her with.
I suppose youre right on the space front. I have a MythTV box connected to my main TV and I have started playing Mame games. The TV connection further restricts the guns I can buy (currently one). Currently I can make a full games machine for less than 300GBP and still use if for recording TV etc. Much better than a games console.
As a PC games player I am really tired of not seeing any nice game input devices. I wanted to buy my self a light gun and there are 3 choices. Two are poor accurecy and the third looks rather pathetic. Light guns for all consoles look and feel so much better. Secondly there are loads of other things you can plug in: dance mats, air guitars/bongo drums, bazooka launchers, virtual girlfriends.... What do we get? Mice errrmm... nope that's it.

I did a short review and benchmarking of unix compressors people might be interested in.
