mikejmoffitt··on Volume – The world’s first personal volumetric display
Fun idea, but the resolution is absurdly low, and as an emissive display it won't be able to block light (show dark things) without trickery or some drawbacks (like tinting the view glass, or requiring all lights to be off).

"people of all ages can come together to experience something that’s future AF."

Is the target audience "gullible ass"?

How the mighty have fallen.
mikejmoffitt··on Windows 10 Embedded Product Key Tool
The little-sung secret technique for removing dinky laptop stickers is to use a piece of adhesive tape to pull up the remaining gunk. For whatever reason, the stickers seem to be affixed with the most tenacious glue available.
mikejmoffitt··on A Pixel Artist Renounces Pixel Art (2015)
High-res pixel art is tough - to create, and sometimes to enjoy. When the goal of pixel art is to create something interesting when imposing resolution constraints, the significance of a single pixel is reduced when working with such a high resolution.

Further, if the viewer's display is _close_ to the art's native resolution, but not at least one integer multiple higher, the art is going to be smeared as no scaling technique will deal with such a small scaling transition well.

With that in mind, Auro looks like it'd have trouble looking good on any of the devices it was intended for, and indeed looking more like aliasing ("pixellation") to the average user. The author acknowledges this in the article: "Some devices blur Auro. Some devices stretch it. Some devices letterbox it. No matter how hard I worked to make the art in Auro as good as I could, there’s no way a given person should be expected to see past all those roadblocks."

mikejmoffitt··on How to Hack an Election in 7 Minutes
What is the likelihood of this voting machine (or ones like it) being used in an election in 2016? From the article's picture, I see several 8-bit EPROMs in sockets. As much as I love this technology, I would expect that something newer is being used that may be a little less trivial to muck around in.

That said, a "more modern" solution might mean (Windows XP Embedded | a Web front-end | any other un-formally-verified horror show).

mikejmoffitt··on “The WorldWideWeb (WWW) project aims to allow links to information” (1991)
The interesting thing is how much TV _hasn't_ changed as a format. The resolution has increased, the aspect ratio has changed, but these are simply parameters. Fundamentally, we're still sending signals that get decoded to form a linear stream of data, line by line, with the same blanking and synchronization signals as would drive a CRT monitor. The color encoding and compression is very different, as is the horizontal scan rate (and subsequently the number of lines).

As a paradigm, it's not too far off from what we had before. I think the web has taken a much larger step away from its original requirements and implementation details.

You've described using a phone as a mass storage device.
mikejmoffitt··on A Proposal for a High Resolution Display (2009)
Increasing resolution makes it _better_, but the same resolution with square RGB arrangements will do a better job for the aforementioned contexts.
mikejmoffitt··on A Proposal for a High Resolution Display (2009)
This kind of display is poor at representing hard, orthagonal edges, which drive much of our user interfaces, lots of text rendering, and pixel art.
mikejmoffitt··on Interviewing my mother, a mainframe COBOL programmer
"We used to have personal desks, but now we have this “pick whatever spot is available” open area. I dislike it a lot."

This fits in line with what nearly everybody I know thinks. Does anyone _actually_ like open-plan offices without dedicated desks? How long until that trend passes?

mikejmoffitt··on Nintendo re-releases NES as mini console
It improves surface contact. That it works isn't a myth at all. Many people mistakenly put the blame on dust, thinking that blowing on it remove the dust which made it work.

It's not great for it in the long term, though, but hardly as damaging as much of the smug internet would want people to believe.

mikejmoffitt··on Nintendo re-releases NES as mini console
Replacing the battery takes a couple minutes. Many of those carts are still running. The number of decent NES games that used battery saving can be counted on your hands, so to call it a LOT of pain might be exaggerating a little.
mikejmoffitt··on Nintendo re-releases NES as mini console
The NES cartridge's pin pitch is nonstandard, and making a new slot for it is actually a very expensive endeavor. You can get "close" with standard parts, but the resulting tolerance is extremely low.
mikejmoffitt··on Nintendo re-releases NES as mini console
The most recent Sega units by ATGames are emulated, and they do an absolutely terrible job. Many of them have the FM sound channels out of tune with the SSG sound channels. It's a great way to get a terrible impression of the games offered for it.

The older TV Plug and Play ones, however, had a Genesis-on-an-ASIC, a native licensed silicon clone of the original chipset. These were super accurate, and could even have a cartridge slot wired to them by the enterprising modder. They ran at 3.3v, though, so things get quirky with a real cartridge without proper transcieving logic.

mikejmoffitt··on Xerox Alto Restoration Part 2: Firing up the monitor [video]
If you wait for half a year, I own two rejuvinator units and have used them to restore some tunes. Once I move to the Bay Area I'd be happy to lend them out.
mikejmoffitt··on Broken Hardware, Fixes and Hacks Over 8 Years
Many PSUs do have bleed resistors, but plenty (especially cheaper ones) will not. More importantly, a damaged PSU may have a non-working bleeder circuit, and you'll only know when you discharge a cap. Hopefully across a resistor, rather than a screwdriver, and very much hopefully not an open wound on your skin.

A CRT stores energy because it acts a a large capacitor. Some better monitors (especially late '90s open cage arcade monitors) had bleed resistors on the anode of the CRT to make servicing safer. It's not actually a ton of energy; the voltage is very high, but that's about it. A charged, unpowered tube will sting, but it's seldom a killer. The flyback transformer will give a potentially lethal shock, though. The anode cap has the thick insulation and is surrounded by aduadag for a reason!

mikejmoffitt··on Valve funding VR projects, exclusivity-free, with pre-paid Steam revenue
Steam itself doesn't force DRM on a developer. As an SDK, it provides a very easy DRM platform to choose to use. They offer it, but it doesn't have to be utilized.
mikejmoffitt··on Please Stop “Fixing” Font Smoothing (2012)
The author of this post gives the impression of being unaware of potential color fringe artifacts that crop up with subpixel rendering. The real design crime is allowing a property like this (or WebKit, for that matter) to ignore the user's operating system's preferred font smoothing method.
mikejmoffitt··on Programming the ENIAC: an example of why computer history is hard
This was an interesting read, but I thought the description of the Von Neuman's architectural decision to address program instructions and data in the same address space was a little hasty - perhaps introducing the Harvard architecture or another with separate spaces would help with the argument for ENIAC categorically being a computer.

A little kapton tape tints it to a less irritating and warmer tone.
mikejmoffitt··on Unknown Neo Geo Fighting Game Discovered and Dumped
A late page of the C ROM data looks like it contains data from Money Idol Exchanger, so I think this game was developed by FACE.
mikejmoffitt··on You can’t let a broken CRT monitor stand in your way
The problems being described sound like capacitors that have gone bad in the deflection circuitry. In the world of arcade machines, which run CRT monitors for hours on end every day, this failure mode is very common, and it shows as a "curl" on one or more sides of the display.

Never mind that in order to use a voice service, it requires you to speak at a rate slower than many can type, all while demanding that the people in the room hush up so it won't get confused. Repeat if there was a mistake.

Seconding this. Websites shouldn't push a preference like that on users.
mikejmoffitt··on Ask HN: Is Knuth's TAOCP worth the time and effort?
You can't run the car on it, but many subsystems in any car, automatic or not, can and will run on that sort of machine.
mikejmoffitt··on OpenBSD laptops
Lenovo support has been great to me as well. With my second-hand machine, a year out of warranty, they paid to have my laptop shipped to them for a keyboard and possible motherboard replacement for free. This is after I'd damaged the keyboard by intentionally testing, "How well DOES the water drainage system work?" by pouring water into the keyboard. I was frank with them about what happened, and it did not matter.

I got briefly excited that maybe somebody decided to post my computer game called "Ghost in the Machine" on HN, but then naivety died down and I read the rest.
