KeytarHero··on IKEA introduces wireless charging furniture [pdf]
> True. They probably should have used some Lumias and Android phones since there are plenty of those that look sufficiently glamorous for these photo shoots and won't leave observant technical audiences feeling misled.

You obviously didn't even open the link - the very first thing you see on page 1 is a Samsung (Galaxy S4, I think?).

KeytarHero··on Game of Thrones leak and watermark: a stupid tracking system
> Either HBO is using these and nobody knows yet

I suspect this is the case. It seems like people are assuming HBO's silence means they didn't use a steganographic watermark. I disagree; I don't see any reason why they would feel the need to tell the world - especially if they plan on pursuing this legally.

KeytarHero··on $149 Chromebooks
> There are no native apps on ChromeOS—the correct question is not "Can Mozilla write a browser for ChromeOS", its "Can Mozilla write an app for ChromeOS"

Exactly - ChromeOS is a browser. "Can Mozilla write a browser for ChromeOS" makes about as much sense as "Can Mozilla write a browser for Chrome" or "Can Google write a browser for Internet Explorer".

...or it would have made that little sense before Mozilla wrote a browser in html: https://github.com/mozilla/browser.html

KeytarHero··on Super Mario 64 HD
But they are patentable (or at least elements of them can be). Konami successfully sued[1] the makers of In The Groove, a Dance Dance Revolution clone. I know parts of Mario Kart are patented[2], so I wouldn't be too surprised if parts of Super Mario 64 are patented as well, given that it pioneered the 3D platformer genre.

KeytarHero··on Psychology of ‘no': Vancouver transit vote shows why good decisions are hard
Referendums don't directly happen for issues like that, but they do happen indirectly through the parties we vote for. Say there was a party running for city council called the "Get Rid of the Bikes Party", where that was their main platform. Would you still encourage everyone to vote for what helps themselves personally?

If everyone voted for just the things that helped them and against everything else - whether in referendums, elections, whatever - minorities would pretty much always be repressed.

> Here is an idea: everyone should vote in a completely myopic way based on what is immediately good for them today.

If Vancouver had a referendum to get rid of bike lanes and ban bikes from streets entirely, I doubt you would be saying the same thing. There are far more drivers than cyclists. I guess in that case all the drivers should vote to get rid of bike lanes and ban cyclists?

Surely biking to work is easier if there are fewer cars on the road?

KeytarHero··on FAA says monetized videos shot from drones are subject to commercial regulations
Does this mean if YouTube flags a drone video for copyright, now YouTube is the party that's breaking FAA rules because they're the ones using drone footage commercially?
KeytarHero··on The new MacBook
It's because the last few versions of OS X and Apple's applications have seen bigger changes than previous versions. And a lot of the more hardcore Apple fans tend to dislike change. A lot of Apple's more long-term fans hated OS X when it first came out, too.

I'm not trying to bash Apple fans when I say this - I'm an OS X user too, and admittedly I only finally moved on from Snow Leopard last year (I actually like a lot of the changes, and most of the ones I don't like are ones that are easy to ignore). This phenomenon is certainly not exclusive to Apple fans either - just look at how many people still refuse to upgrade to Windows 8.

KeytarHero··on Soviet Space Image Catalog
No idea, but assuming it belongs to Russia, I'm sure they're okay with pictures that make the Soviet space program look good being shared.
KeytarHero··on “Just the Beginning of What We Can Do on Super Nintendo”
A little OT because it's not what they're doing in this case case, but...

The NES and SNES (and I'm guessing other cartridge-based consoles) supported having extra chips (often called "mappers") inside the cartridge that would add extra hardware capabilities beyond what the console could do by itself. Basic mappers could switch between different ROM banks, effectively allowing games to have larger ROMs than the console would normally allow. Later, some cartridges would have co-processors that did some of the computation inside the cartridge itself in order to enhance graphics capabilities. That's how the original StarFox was able to run on Super NES, despite the SNES not supporting 3D polygon rendering.

For a while[1], I've wondered what a NES would be capable of if you used a modern ARM SoC - say, a Raspberry Pi - as a mapper. For one, you could make a NES game with WiFi support (you wouldn't even need an ARM chip for that, just an ESP8266 should be able to do the basics). I'm not sure if this is possible, but in theory you could even do all rendering on the ARM chip and output the image directly to the video buffer, effectively allowing you to do just about any graphics the SoC can do. As for audio, on the Famicom (the Japanese NES), there were actually extra analog audio pins for cartridges that would allow a cartridge to output any audio it could generate. The NES doesn't have these pins, but I think you could still do higher-quality audio than the NES is normally capable of by rapidly changing the DMC channel.

I don't know much about NES programming nor really anything about its video hardware, but this is still an idea I've had in the back of my mind for a while.

I know some people might ask "What's the point? All you're doing is making it harder to use a Raspberry Pi!", but I think it would be pretty cool to say you did all that with something that's technically a valid NES cartridge running on an unmodified NES.

[1] really, I first got this idea when I saw Google Maps' 2012 April Fools joke - I started thinking about how a NES-based Google Maps would technically be possible

KeytarHero··on The Photoshop of Sound
From TFA:

“Each table is in its own sonic zone,” John explained. “But it’s not isolated.” He mentioned a colleague’s earlier attempt to address restaurant noise, which succeeded in suppressing chatter but led to a muffled, sterile environment: “Everyone hated it—the room ended up being completely dead.” Instead, Constellation undertakes a process akin to the Photoshopping of an image, with undesirable elements removed. John explained that there are two components to a sound as it resonates: the early reflections, which contain most of the intelligible information; and the later reverberation, which is blurrier. “Right now, with those loud people right behind me, we’re hearing only their reverb energy—it’s not enough for intelligibility. Early reflections have been cut out: you can hear voices but not what they’re saying.” The effect is conviviality without chaos.

KeytarHero··on The volume is too damn high on flights
Well, in most cases the stage volume is already in so-loud-you-lose-clarity territory, so the clarity you gain from the sound guy turning up the mains a bit is worth the clarity you lose due to the extra volume. We're not talking massive increases in volume here.
KeytarHero··on The volume is too damn high on flights
At small venues it's often just because the band is playing loudly. Some drummers play pretty loudly, some guitarists play amps that sound better with the volume cranked, and then singers are going to want the vocals louder in the monitors so they can actually hear themselves over the loud drums & guitar.

If stage volume is loud, the sound guy is likely going to push the volume even louder, both so that he has some level of control over it, and because sound coming off the mains is going to sound a lot clearer than if you're hearing everything off the stage monitors and then reflected off the back wall (yes, even if that means things are louder, they can still be clearer).

KeytarHero··on Inside the Tragic, Obsessive World of Video Game Addicts
Incredibly cheap in terms of financial cost, but not in terms of opportunity cost of the time you lose.

Admittedly I haven't read the article because Vice is blocked at work, but I imagine video game addiction is a lot different from other addictions since it has to do with something you do rather than a state you're in (not to say it's necessarily worse - just different). Serious addicts can play video games for several days straight, whereas I don't think doing drugs for several days straight (at least without doing anything else) is common among even the most serious addicts (though admittedly I'm not an expert in this). I think it would be very difficult to be a "high functioning" video game addict.

KeytarHero··on Hands-On with Microsoft's New Holographic Goggles
HPU isn't really much of a "new technology". It's just a custom coprocessor, not all that different from the motion coprocessor in the iPhone (except designed for video processing, so presumably a lot more powerful).

KeytarHero··on College Students Prefer Reading Print Books to E-Readers
OneNote on my Surface Pro is about the best thing I've found, and yet it still has major flaws (this is without even getting into how bad its pdf import is). Capacitive touch + active-digitizer stylus can solve a lot of the problems with ebooks (and indeed does, particularly as far as annotation is concerned), but the software is still severely lacking.

The main UX challenge that I haven't found anything has really solved yet is the ability to show 2 or more pages at once (and do so in a way that's simple & intuitive). Also related is some way to mimic the ability to, with a textbook, stick a pen or finger in between two pages as a "temporary bookmark", to make it easy to flip back & forth.

Now that the hardware has caught up to where it needs to be, I think e-textbooks have the potential to get a lot better as software improves. I don't think the physical book will ever die, but I do suspect that ebooks will be much more prevalent in 10 years than they are now, when the software has finally solved UX challenges like these.

KeytarHero··on SpaceX: “Close, but no cigar. This time”
Can't we just appreciate how both are fascinating for entirely different reasons? I think it's pretty amazing we were able to get a rocket to land (edit: well, almost land) to this precise a spot - and all by itself, without human pilots. Sure, it's no moon landing, but it has certain other challenges the moon landing didn't have. I think both are really cool.
KeytarHero··on A lucky little fish solves iron deficiency among women in Cambodia
> The problem of iron deficiency can be solved with iron cooking pots, or pieces of iron not shaped by fish.

can be is a whole different thing from is being. Or, to use the old, tired cliche, "you can lead a horse to water but you can't make it drink"

There are several steps to solving iron deficiency. Yes, an iron cooking pot or a plain iron pellet solves one of those steps. But the human step is every bit as important.

It's clearly not just a matter of aesthetics either - it's "a piece of iron shaped like a local river fish believed to be lucky". Sure, saying "they're dumb and should just learn to use a round pellet" makes sense from our educated western perspective. But that's completely ignorant of their deeply-ingrained cultural attitudes. When you're in a society that believes a certain kind of fish to be lucky, you can't just say "use science, idiot" and expect them to actually do what you say. As a more extreme example, remember that in Liberia, armed men broke into an Ebola clinic to free patients [0]. In cases like these, the human side of the problem is far more important than the scientific side.

KeytarHero··on Korean Fan Death
I've also heard it was propagated by the Korean government so people would save electricity from not running their fans or air conditioners all night in the summer.

The Wikipedia article does have a citation from 1927 [1], though, so it would seem the origins are much older than that.

My guess is it's a bit of all of the above. Maybe there was a little bit of belief in it, and the government, but government efforts to reduce energy usage as well as families using it to cover up suicide or drug overdoses helped propagate the belief and make it far more widespread.
