Old Doesn't Have To Mean Ugly: Squeezing Better Graphics From Classic Consoles

Guspaz Re:This is a stupid product only for idiots. (163 comments)

Indeed. And I want a box that will simulate the experience of a CRT on a high-res LCD, not make it pixel-perfect. I want subtle screen curvature, I want scanlines that actually look like they're on a CRT (simulating how bright and dim scanlines are different sizes) and not just sticking black horizontal lines on the image, I want NTSC composite artifacting, I want to simulate a CRT's subpixel pattern...

Ironically, I can do all that with filters for emulators, but not with a real SNES. It's surprising to me that nobody has stuck an FPGA between a composite input and an HDMI output and stuck a CRT simulating pixel shader in the middle.

Old Doesn't Have To Mean Ugly: Squeezing Better Graphics From Classic Consoles

Guspaz Do not want (163 comments)

When I use a SNES emulator, I jump through hoops to make it look like it did when I was growing up, simulating a CRT television and the artifacts of composite video. Why would I want to take my SNES and try to make it look like an unmodified emulator? That's the exact opposite of what I want. These games were never meant to be hyper-sharp and pixelated. In fact, some games rely on composite artifacting to make certain effects work.

In fact, I want an upscaler that I can plug my SNES into that will simulate a CRT. When I emulate, I combine a CRT simulation filter (which gives me a simulation of CRT scanlines and subpixel geometry while simulating the curve of a CRT) with a composite video simulator (which simulates the artifacts of composite video), and the results is very pleasing, looking much like I remember things from back in the day. With a real SNES, I don't need the composite simulator, because I can just use the real SNES composite output, but having a hardware device that does the CRT simulation (perhaps doing the CRT simulation shaders on an FPGA?) would make it look much better on an LCD or projector.

I realize that you can get partway there by running the SNES signal through a scaler to get to 480p and then running it through a scanline generator, but that's not simulating the physical properties of a CRT (like how a bright scanline appears thicker than a thin one), you're only getting partway there.

Guspaz Re:Just buy a CRT (163 comments)

Slight difference: a big ass-free CRT is desirable, while a big ass-CRT would be undesirable.

Huh? You've linked to an article of Netflix asking for the merger to be blocked.

Ask Slashdot: What To Do About Repeated Internet Overbilling?

Guspaz Re: maybe (349 comments)

Except it's not irreducible, it's an explicit choice to use ATM. Many variants of DSL (such as the VDSL2 that is all companies like Bell Canada deploy these says) don't require ATM. Of course, replacing outdated hardware with VDSL2 hardware has a cost too, but the companies should be (and are) doing that anyhow.

Guspaz Re:maybe (349 comments)

That 15% is far more from ATM (9.4% overhead) than PPPoE (0.5% overhead), and Bell Canada's newer services (VDSL2, GPON) are unaffected as they no longer use ATM.

Dropbox Caught Between Warring Giants Amazon and Google

Guspaz Dropbox brought it on themselves (273 comments)

Unless I'm mistaken, Dropbox has never invested in infrastructure. They rely on S3 for storage, which is extremely expensive. If they had invested in their own infrastructure, they wouldn't be in this mess... or at least they wouldn't be quite so deep in it.

BackBlaze faced a similar challenge, and decided to build their own infrastructure, going so far as to build their own custom server chassis. They rely on consumer drives with redundancy to reduce costs. The result? Their one-time up-front storage cost is $0.05 per gigabyte, meaning that it's economically feasible for them to offer their customers unlimited storage for five bucks a month. Amazon, for their part, charges $0.33 per gigabyte per year (in bulk).

Their infrastructure isn't quite exactly what Dropbox would need, but it's not that far off, and their costs drop based on ever-decreasing storage prices, rather than when a cloud provider feels like lowering sky-high storage costs.

AMD Launches Radeon R7 Series Solid State Drives With OCZ

Guspaz Re: Marginally better (64 comments)

Why would Toshiba having bought OCZ make me any more willing to trust them? I've been burned far worse by Toshiba (whose salespeople lied to me to make a sale and whose support people refused to honour my warranty) than by OCZ.

AMD Launches Radeon R7 Series Solid State Drives With OCZ

Guspaz Re:Marginally better (64 comments)

At least Amazon has a track record of making decent hardware. The existing Kindle products are pretty nice.

OCZ has a track record of making terrible SSDs.

Is Dolby Atmos a Flop For Home Theater Like 3DTV Was?

Tesla Removes Mileage Limits On Drive Unit Warranty Program

Guspaz Re:So there is a problem... (174 comments)

You got modded as funny, but it's not supposed to be. The Tesla has a battery heater that will kick in to keep the battery from getting too cold, and leaving it plugged in will avoid power drain from that.

Berlin Bans Car Service Uber

Guspaz Re:Picking nits.. (341 comments)

When I "Uber" a ride, I get a regular taxi. They call it "uberTAXI", and it's the only service available in the second largest city in Canada. A regular taxi shows up, and you get billed the regulated meter rate.

About the only advantage is that Uber's app is probably more reliable/better than the very similar apps used by existing taxi companies in Montreal. I've had Diamond Taxi's app crap out on me after ordering a few times, and the GPS on the taxi only updates infrequently.

Apple's App Store Needs a Radical Revamp; How Would You Go About It?

Guspaz Re:Two things.... (249 comments)

And introduces a whole lot of new ones. People rail against Apple's control over app store listings, but it really does go a long way to significantly reducing the amount of malware users get exposed to. Not all of it, to be sure, but most of it.

They could probably allow a bit more freedom by still curating their own app store, and forbidden alternate app stores, but allowing some form of manual side-loading that is sufficiently non-automated to ensure people don't get tricked into installing malware.

Google Expands Safe Browsing To Block Unwanted Downloads

Guspaz It's broken (106 comments)

It's currently blocking all downloads of software from dropbox. Which is super annoying. I kickstarted a game for the Oculus Rift, and the developer was trying to distribute the demo to his backers via dropbox, and Chrome is blocking it.

NVIDIAs 64-bit Tegra K1: The Ghost of Transmeta Rides Again, Out of Order

Guspaz Re:Is it better? (125 comments)

Errm, it's a dual-core chip, and there's no third core for running the optimizations. They run on the same CPU cores that everything else does.

Google's Satellites Could Soon See Your Face From Space

Guspaz Google already has high-res imagery (140 comments)

Google and other online map-providing companies supplement satellite imagery with aerial photography, and as far as I know, there are no limits on that sort of thing.

How to report Linux kernel violations?

Guspaz Guspaz writes  |  more than 6 years ago

Guspaz (556486) writes "I recently bought an ADSL modem/router (the VersaXpress VER170PR) made by a company called VersaTek (http://www.versatek.com/). When I noticed that the modem ran Linux (2.6.8.1), as many routers do, and that it did not include any mention of the GPL, I sent an email to the company requesting a copy of the source. Their response was that the modem was made by an OEM in China, and that they didn't write any source code, and didn't have any to give.

I've sent them a second message explaining that selling or distributing their modem without a copy of the source or an offer to provide it is copyright infringement. I'd like to report it, but I have no idea how to proceed. Who should I contact to report a violation of the GPL as it pertains to the Linux kernel, and how should I contact them?"
