SpaceX Releases Video of Falcon Rocket's Splashdown

Guspaz Re:What flyout and back plan? (49 comments)

At the point where the booster separates, it has burned most of its fuel, and weighs a fraction as much as it did at launch. As a result, it requires far less fuel to kill its velocity and put itself on a trajectory back towards the launch site than the initial launch did (far less mass to accelerate on the return trip).

It does still require some extra fuel (hence why they talk about having to use expendable Falcon 9s for missions that are close to the max payload capacity until they can get Falcon Heavy flying), but for small to medium sized cargoes, they have the fuel to burn.

The "Rickmote Controller" Can Hijack Any Google Chromecast

Guspaz Re:Maybe it's just me ... (131 comments)

They're not out $35, it's basically a jammer, and only works while in range of the chromecast's wifi.

A wifi jammer would make the chromecast just as inoperable.

White House Punts On Petition To Allow Tesla Direct Sales

Guspaz Re:He cant or wont? (382 comments)

*shrug* I don't see why that would be a big deal. I'm Canadian, where in a majority government, the prime minister can basically do whatever he wants for four years. The limitations are what the supreme court says will fly with the constitution, and the knowledge that if you do something too unpopular, your party will lose the next election and somebody else will get to form the government. Or if you go way too far overboard, you might have a cabinet revolt to pick another party leader (and by extension prime minister).

The american system where the leader of the country is at odds with the representatives seems very inefficient to me. Why is the person ostensibly leading the country not the one deciding what the government should do? Why else are they the leader of the country? I don't see how American governments can get anything done without the stability of a leader empowered to make decisions that have impact.

White House Punts On Petition To Allow Tesla Direct Sales

Guspaz Re:He cant or wont? (382 comments)

The American constitution grants their federal government the power to regulate interstate commerce. Laws forbidding an out-of-state manufacturer from selling directly in a state would seem to fall under that category. The constitution does not expressly forbid such activity, so far as I can tell, but it does mean that the federal government has the jurisdiction to override them.

Nano-Pixels Hold Potential For Screens Far Denser Than Today's Best

Nano-Pixels Hold Potential For Screens Far Denser Than Today's Best

Guspaz Re:What's the point? (129 comments)

VR and AR are something, as are things like the Google Glass, but another one is EVFs (electronic viewfinders), which typically use microdisplays.

Then again, these microdisplays already feature pixels FAR smaller than what they're claiming these new "nanopixels" are.. the article is kind of confusing. They seem to be claiming pixel sizes a bit less than half what an iPhone has, but there are already smartphones out there with pixel densities almost double the iPhone (like those phones with 1440p displays), and microdisplays go many *times* more dense than that, so... what's new here exactly?

Amazon Seeks US Exemption To Test Delivery Drones

Cars have to deal with traffic. Amazon already has same-day delivery by road in some cities, but not in 30 minutes.

Ode To Sound Blaster: Are Discrete Audio Cards Still Worth the Investment?

Guspaz Re:No. (502 comments)

It's not just HTPC. Digital audio is also used for spears that use a digital connection (my 15 year old 4.1 PC speakers do), any USB headset, etc.

Ode To Sound Blaster: Are Discrete Audio Cards Still Worth the Investment?

Guspaz Re:No. (502 comments)

The number of hardware channels supported isn't really relevant anymore, since Windows moved to an all-software based sound architecture years ago (with Vista, I think it was?)

Ode To Sound Blaster: Are Discrete Audio Cards Still Worth the Investment?

Guspaz Re:HDMI has killed the need (502 comments)

If you're using HDMI or some other digital output, the "hardware in the middle" isn't generating any audio, it's just passing along the digital information that was generate in software, or better yet, if you're bitstreaming, stored in the original recording.

Heck, when you're using audio over HDMI, your soundcard isn't even involved in the process, it's your videocard that's handling the audio data.

Ode To Sound Blaster: Are Discrete Audio Cards Still Worth the Investment?

Guspaz Re:No. (502 comments)

Soundblaster cards haven't done FM synthesis for decades. If you want to experience that today, you're going to want to do that with an emulator. Luckily, there are lots of Yamaha OPL-3 (the chip that the SB16 used for FM synthesis) emulators available. DOSBox has several, I believe.

Ode To Sound Blaster: Are Discrete Audio Cards Still Worth the Investment?

Guspaz Re:No. (502 comments)

And those noise problems don't matter if you're using digital audio connections, say over HDMI or TOSLINK or S/PDIF. In fact, if you're doing digital audio over HDMI, you're not even using your onboard sound, you're using your videocard's sound output.

Even then, the signal-to-noise ratios of onboard has been good enough for years now. Sure, you might notice a slight difference with a good pair of headphones, but in practice, not so much.

Alcatel-Lucent's XG-FAST Pushes 10,000Mbps Over Copper Phone Lines

Guspaz Re:However this begs the question.... (149 comments)

That's because you're on an interleaved profile rather than fastpath. Your ISP has, on your line, sacrificed latency for improved error correction.

Guspaz Re:However this begs the question.... (149 comments)

First-hop latency on VDSL2 is less than one third that...

My first-hop latency is 12ms, and that includes a 600 kilometer journey from my DSLAM to my ISP's closest PoP in another province.

Did you look at the video I linked to? "Get ready to print 10x faster" is definitely a claim made in the video.

Tesla Aims For $30,000 Price, 2017 Launch For Model E

Guspaz Re:What about range on this smaller car? (247 comments)

The distance travel thing is perhaps not ideal now, but that's a problem that will be solved in time: Tesla alone is building a ludicrous number of such stations along highways in US/Canada/Europe, and their recent patent moves indicates that they'd like to improve on that even more by having other car companies build their own compatible stations and everybody shares all of them. They can probably never share the swap stations (just because the requirements on the car side of things for that would be way too specific), but just getting more charging stations would help a lot.

In terms of not wanting to miss a charging station, that shouldn't really be an issue, as you can have the car's satnav automatically hit up the charging stations along your route, so that you don't need to think about it.

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?"
