Comment What is all that data good for? (Score 2) 223

News about ad networks doing evil tracking and such comes up all the time, but I have to wonder what all that data is any good for? I don't use ad block and yet all the ads I see tend to be either be pretty unimpressive and untargeted. They might know that I am male and they might be clever enough to show video games advertisement on a video game site, but that's about it. In a lot of ways the targeting makes the ads actually worse, as they end up covering a far narrower range of products and lead to a lot of repetition. Youtube can be notoriously bad at this, showing you the same ad 20 times in a row. There are also some ads that are extremely personalized, but they are unimpressive in the other direction, Amazon ads for example will just show me products that I just watched on their site. So won't show me anything new, just stuff I am already familiar with.

Never seen ads that actually extrapolate my behavior and interest and end up recommending me a product that I would actually be interested in buying. I found good old untargeted advertisement on TV or magazines far more useful for that, as that showed a lot of products that I didn't even know existed.

I think it's not so much that it isn't fast enough, but that you end up with a big box with a big spinning mirror. What he wants to do is to take the same technology and replace the spinning mirror with a DLP-style micromirror, thus you could do the same thing much smaller, cheaper and with less power, which in turn would allow you to have more of those devices for better tracking.

Overclocking processors generally voids the warranty and in general overclocking isn't something that appears in marketing materials for most or all processors.

Actually the box of my AMD FX-8320 reads:

* Unlocked out of the box
* Achieve ultimate power with up to 5.0Ghz and 8 cores
* Overclock your system for supercharged performance

The joke is when you read the included papers inside of the box:

Use only the heatsink/fan provided. Use of any other heatsink/fan will void warranty

Differences when compiled can be shrugged off as different compiler versions.

Yep, and it's not just different compilers, time stamps, compile order on parallel builds, the order of files in the filesystems, install path, compile flags, etc. will all change the resulting binary. Reproducible builds just hasn't been a thing in Free Software community and only very recently did Debian start work on ensuring that their binaries are byte-for-byte reproducible, but that's of course just Debian, we are still far far away from having reproducible builds be the default way how Free Software binaries are distributed.

Can you elaborate on why Patreon disgusts you?

I wouldn't call it disgusting, but one problem with a service like Patreon is that it only really works for people who produce regular content updates. So if you are a blogger or Youtube, it can work great, on the other side if you do a create a great single player mod that only gets released once after month of work, it becomes much harder to make money with it. There is also the risk that people that bundle other peoples mods into mod-packs will end up making much more then the people that actual do the mods, as they can produce far more frequent updates and thus gain better visibility.

So there is nothing fundamentally wrong with Patreon, it just has a different set of short comings then one-time-pay-mods.

Comment Re: but I thought 90fps was the thing (Score 2) 35

The 90fps is pretty much required everywhere, as the issue is your head motion, not the action happening in the game world itself. If the screen image and your head motion aren't in sync the whole virtual world is wobbling around and can make you motion sick extremely very fast. However both Sony and Oculus have a form of timewarp frame interpolation that can take the last rendered image and reproject it to your new head position, this allows smoothing out lower framerates a little. Sony is using it in some games all the time to scale an 60fps input to a 120fps output. On the Rift it's used more as an emergency tool when the framerate dips.

Comment Should have added screen cap support into Firefox (Score 2) 406

Bending over and adding DRM might not exaclty be a good thing, but I can see how it might be necessary if they want to stay relevant. Though I have to say they really should have waited with that until DRM actually becomes relevant to the Web, jumping on the DRM train this early is really sending the wrong signal. Anyway what they should have done it also just ship the anti-DRM messures right in the browser as well. Add a function to screen capture videos of your browser interaction isn't all that difficult and would have nicely shown just how pontless the whole DRM thing is.

Comment Re:maybe KDE will be next (Score 4, Interesting) 693

Right now in Xubuntu: The WindowButtons/Taskbar shows the wrong windows when using multiple monitors, the xfce-volumed is constantly hanging, not registering volume keys and using the wrong soundcard, the indicator-applet is completely broken and putting apps into fullscreen doesn't work properly any more either with multiple monitors. Most of this used to work a year or two ago. It feels like XFCE is just getting more and more broken as time progresses. It's pretty frustrating, guess it's time to try Mate.

Comment Re: approximately the resolution of an adult eye @ (Score 2) 217

While 538PPI might be a bit overkill on a classical phone, those same screens are also used in the latest round of virtual reality headsets and they have still a long way to go before they get anywhere near human vision limits. And to go even further, Nvidia has demoed some microlens lightfield glasses a while a go and those need even more resolution then a classical headset display and who knows, if resolution keeps growing, having a lightfield display in your phone might actually start to become viable (meaning you could have a real 3D with proper focus, could hold your phone close to your face to use it as VR glasses and other funky sci-fi stuff).

Comment Re:Dubious commercial prospects (Score 2) 100

already had very low persistence (60Hz display refresh, same as the new OR, but horrid resolution)

"Persistence" in this case doesn't just mean a higher refresh rate, but the time the image is on the display. With a classical LCD the image is on the display all the time, that's ok when you read text on a monitor, however for VR this leads to artifacts. When the image is on all the time and you move your head your eyes will receive an incorrect image until the next frame shows up, this leads to a lot of blurring and judder. With low persistence on the other side a frame is just flashed for a short amount and then the display goes black again (kind of like a CRT), meaning your eyes will receive always the right information and the judder and blur disappear. The black in between frames is filtered away by your brain. Abrash has some nice blog entries on the topic.

Because the "wind in the sails" probably isn't as strong as you think.

Sony is now building their own VR headset for the PS4 with Project Morpheus, Valve already has VR support build into Steam, plenty of games started adding VR support and in the last year more virtual reality demos got produced then in the previous 20 years. Hard to tell how long the wind it will hold, but it's orders of magnitude stronger then what we had 20 years ago. It's also not limited to games, the current DevKit1, with all it's problems, is already used in a few non-game instalations, virtual fashion shows, movies, porn all that stuff. Also the nausea problems with VR have only recently been fixed with proper positional tracking and low persistence displays, something no previous consumer VR display had and that is critical for mass adoption. Given that the hype has been constantly growing ever since the first prototype was revealed almost two years ago, I doubt that VR will just fade away again, people want it, the price is cheap enough and it provides an experience that can't be provided by any other available technology.

All power corrupts, but we need electricity.
