AFAIK in Europe it is not the musicians themselves who have to pay those fees, but whoever has contracted them. In other words the organiser.
You even have to pay those fees if you let a DJ play a few songs before a band opens. Then you have to get a list of covered songs from any band in advance and report this 'event' to the authorities.
So, in that case it would not be the musician, but the manager of the bar. If that was him like TFA suggests, bang.
...correct. But at his time, this belonged to Austria-Hungary.
Which was actually called the Austrian Empire before 1867, but had the same borders.
So Nicola Tesla was born as an Austrian.
True, I am not familiar with UK laws, but I wouldnt say so.
If he sold the laptop with all its contents and data, then all this now belongs to the buyer, and he can do with the stuff whatever he wants.
In this case a lawyer could clearly argue that the means are justified, even if it damages the reputation of the seller, simply because the seller must have been aware of his personal data and whatnot on the laptop's drive.
Granted, I didnt read through TFA thoroughly, but here's my thoughts on that:
The urge for bigger (and thus more detailed) textures is nothing new. I remember when S3 introduced S3 Texture Compression (S3TC) and they had some tweaked maps for Unreal out - it was a blast. Then M$ licensed it for the upcoming DirectX and dubbed it DirectX Texture Compression (DXTC).
Devs claimed that DXTC was incredibly slow due to the framework, so it essentially only worked on S3 cards with special S3 graphic libs. (MeTaL) I dont have to talk about the S3 market penetration, do I ?;)
The maximum texture size advertised was 2048x2048, then. Given a rather limited bandwidth of AGPx4, which i s roughly 1GB / sec. (talking AGP 4x pumped).
A Savage4 had less than 1GB/sec bandwidth. And in said Unreal levels were barely playable.
Nowadays graphic cards utilize as much as 40GB/sec and above.
So, lets assume the following: S3TC compressed textures sized 2048x2048 were compressed at a ratio of 1:8 A texture would take up around 512 KB.
Now, those mega textures would sport 9x the size. Even compressed 1:8 one texture would take up toughly 135 MB.
While the improvement in bandwidth is ca. factor ~50, the difference in actual size is factor ~300.
If it wasnt really viable then, how (or, more interesting: why) would it be feasible now ?
I am still waiting for a review which can explain a non-Linux person [such as myself] why the GUI is so slow. My guess is that the video card's hardware acceleration is not used.
Take a look at http://kororaa.org/static.php?page=static060318-18 1203.
It is a Live CD that is showcasing the latest developments of 3D accellerated GUIs.
Just burn it, put it in your drive and boot your rig - how more newbie-friendly can it possible get ?
ad 3.) also, insurance is an issue when speeding or high speeds are a reason for an accident. Most insurances back off when you go past 160kph and an accident occurs. (wether or not you actually cause it, does not matter)
ad 1.) yeah, there is no "TÜV", "pickerl" or whatsoever in the states. if it drives, you can drive with it on the roads. period. this is imho the reason #1 for accidents in the states. in my list, the by-far-too-easy-to-get driver's license is only #2.
And I'd like to add another point: Seasons! Germany already passed a law to make winter tyres mandatory during winter (duh), and many other European countries are discussing it. I know that people in the USA, even in regions with quite cold and snowy winters drive the same tyres all year. This is much cause for accidents, Im certain.
I spent a few days in a hotel in London, around march. The mini-bar in the room was RFID-equipped and would automatically charge your account if an item was removed.
So I guess thats not really new, then.
Abstract - It was in 1942, when the later Nobel laureate Hannes Alfvén published a letter, stating, that oscillating magnetic fields can accelerate ionised matter via magneto hydrodynamic interactions in a wave like fashion. These waves were later called "Alfvén waves", in honour of their discoverer. Although the evidence for Alfvén's hypothesis came already rather early with the observation of certain plasma phenomena, such as being connected with high solar wind Wolf- Rayet stars, more than 60 years had to pass by before a technical implementation of Alfvén waves for propulsive purposes was proposed for the first time. The name of the concept, utilising Alfvén waves to accelerate ionised matter for propulsive purposes, is MOA - Magnetic field Oscillating Amplified thruster. Alfvén waves are generated by making use of two coils, one being permanently powered and serving also as magnetic nozzle, the other one being switched on and off in a cyclic way, deforming the field lines of the overall system. It is this deformation that generates Alfvén waves, which are in the next step used to transport and compress the propulsive medium, in theory leading to a propulsion system with a much higher performance than any other electric propulsion system. Based on computer simulations, which we conducted to get a first estimate on the performance of the system, MOA is a highly flexible propulsion system, whose performance parameters might easily be adapted, by changing the mass flow and/or the power level. As such the system is capable to deliver a maximum specific impulse of 13116 s (12.87 mN) at a power level of 11.16 kW, using Xe as propellant, but can also be attuned to provide a thrust of 236.5 mN (2411 s) at 6.15 kW of power. Although a dual-use system, space propulsion is expected to be the prime application for MOA. As MOA works best in high-power mode and with ionised matter, utilisation concepts range from a high-efficient Nuclear Electric Propulsion System, to an 'afterburner' for Nuclear Thermal Propulsion Systems. This wide range of applications makes MOA a unique accessory for any nuclear propulsion system to overcome specific concept drawbacks, allowing a full-fledged hybrid nuclear propulsion system, with attune able thrust / specific impulse parameters, perfectly suited for nearly all types of space missions.
Well, given the fact that the penetration depth is dependant of conductivity (or electrical/magnetical attributes) and frequency.
A 100Ghz ray would penetrate copper only to 0.0667uM (micrometer, 10^-6m).
It is possible to create a reflecting surface for any give nfrequency, given one finds and mounts the corresponding materials with the right eletrical/magnetical properties.
So, theoretically it is not only possible to build a shield for those beams, but to reflect them.
I may be wrong, but I'm guessing they don't cost a few hundred dollars each, though, like GPUs do. (The economies of scale that GPU manufacturers see thanks to the fact that they make millions of these things are really quite nice for keeping prices down.)
While GPUs are "only" being used in common graphics cards, which are "only" being used in the PC market, DSPs are used in a much bigger field of electronic appliances.
Think of measurement equipment, think of the automotive sector, think or aviation, just to name a few.
They have far bigger production numbers.
I think I disagree. How familiar are you with the architecture of modern GPUs? For example, you do know that modern GPUs have upwards of 300M transistors (which is roughly 2x as many as modern CPUs), that most of them are devoted to computational units, etc.?
You are right, but you miss my point. I do not compare GPUs to CPUs.
And, FYI, transistor count is definetley not a good performance indicator. GPUs are quite similiar to DSPs in many aspects, but they are simply "too new". Those programmable shaders are a step in the right direction, but again, I dont compare them to CPUs.
Take a 4096 32-bit float discrete fourier transformation (DFT), and tell me how many cycles it'll take on your general purpose CPU, and I'll tell you that it'll take about 8192 on a cheap DSP (30$ish).
I think the FPGA crowd has been predicting that their day will come "real soon now" for quite a long time now.:-)
Yeah, right. But still, FPGAs are so much more elegantly when it comes to architecture:)

That is not true for the H3xx series. Using the standard (US) iRiver firmware, it plays wma (even protected), mp3 and ogg out of the box.
Also noteworthy, listening to ogg vorbis files on my iRiver H320 does chow up battery faster than listening to mp3 files.
....and certain people actually wonder why there's more (car) accidents on mondays after daylight-saving-change sundays....

well, but its SUNDAY in the UTC(GMT) then, isnt it ?
this is hilarious, because daylight saving time ends one (or two ?) hours after that.
coincidence ?
nice translation, no need to AC, imo.
