  • I strongly disagree with the premise that there’s a “wrong” way to play retro games. Don’t gatekeep. Imagine if people told you not to listen to Pink Floyd unless it’s on vinyl. It would be lost media.

    That said, CRTs present images fundamentally differently than LCD displays, and a lot of developers took advantage of those idiosyncrasies. There are scanlines everywhere. CRT phosphors aren’t square, and appear smaller when darker. Bright pixels can “bleed” into nearby pixels, particularly when using composite signals.

    Before LCDs, many (not all) pixel artists used this to their advantage, basically harnessing the imperfections of analog TV to provide equivalents to anti-aliasing, bloom, extra color depth, and even transparency. Some particularly famous examples came from Sega Genesis games. This video goes into good depth on the whys and hows, and there are some solid examples of the outcomes here.

    I’ve attached examples below (hopefully they upload). If you like the raw pixel art, then no harm done. Enjoy! But if you like the way CRTs interpreted and filtered those signals, you owe it to yourself to look up some shaders for your favorite emulator.

  • I’ve started playing through some classic SNES and GBA games.

    Chrono Trigger – Oh man, this one’s good. The soundtrack is on fire, and the game does a good job at making you feel like your actions make a difference.

    Metroid Fusion – If you told me this was made in 2024, I’d probably believe you. It has a sense of pacing and suspense that I wasn’t expecting for a metroidvania.

    I haven’t gotten very far in either, but so far it’s looking like they’ve aged like wine.


  • The Legend of Zelda: The Minish Cap is one of my favorite games of all time. It’s the last isometric Zelda game, and they made it a swan song. The main quest it pretty short, but it’s the sort of cozy game where doing the sidequests just feels right.

    In the game, you shrink down to the size of a mouse to traverse rafters and explore tiny temples and float on lillypads. It’s the sort of thing that would be no big deal in a 3D game, but is wildly ambitious in 2D. Not only do they pull it off, but they fill the environments with lush, lived-in detail that springs to life when you shrink down and look at it up close. The art style still sticks with me after 20 years.

    Also, forget all the “hey, listen” stuff, your sidekick Ezlo just sasses you the entire time. It’s great.


  • a bit melancholic sometimes

    Viewer be advised: If you’ve ever lost someone you took for granted, or hurried through what should have been a formative time in your life instead of slowing down and appreciating it while you had it, then this show knows how to punch you in the tender bits, and it will not stop.

    I cried during every one of the first four episodes.

  • But we know what it really is all about - selling more cars.

    It isn’t even about selling more cars at this point, it’s about selling securities. Their market cap dwarfs their total sales. Their P/E ratio is 67.67x, meaning they could sell cars for 67 years and still not make as much money as their stocks are worth today.

    The real product is the rising stock price. The factories are just a front.






  • Solid point. A laptop battery is around 60Wh, and charging that in 1 minute would pull 3.6kW from the outlet, or roughly double what a US residential outlet can deliver.

    Supercaps stay pretty cool under high current charging/discharging, but your laptop would have to be the size of a mini fridge.

    The research paper itself was only talking about using the tech for wearable electronics, which tend to be tiny. The article probably made the cars-and-phones connection for SEO. Good tech, bad journalism.






  • Hard disagree.

    This week, I’m designing a circuit which would traditionally use relays, but I’m considering IGBTs instead. IGBTs weren’t designed for my industry, but they’re so cheap (thanks to quadcopters) that I can just overspec them and get the job done despite the lack of optimization.

    Grid scale energy storage was already being researched before the EV boom – remember when people stopped talking about vanadium-flow? EV batteries undercut stationary-optimized batteries in $/kWh because EVs are lucrative enough to drive the research that much harder. Without the EV industry as the incubator for competing battery tech, stationary storage would still cost what it did in 2010.


  • In the USA, out of every economic sector, transportation creates the most GHG emissions [EPA1], and the majority of that is from passenger vehicles [EPA2]. Significant portions of the industrial sector’s emissions come from refining automotive fuel [EPA3]. US total GHG emissions are down around 20% from their peak in 2005, but almost all of that has come from the electrical power sector [CBO1][CBO2]. Vehicular pollution has dramatic direct health impact on top of GHG emissions [HSPH].

    Transport emissions are the long pole in the tent for the US. Solutions to that will be the focal point of US climate strategy for the next decade. Barring the demolition of the majority of US housing to re-establish walkability, our two best solutions are EVs and public transit.

    EVs cut lifecycle emissions by about 55-60%. [UCS][ANL][MIT][ICCT][BNEF][CB][MIT][IEA]

    Public transit cuts lifecycle emissions by… about 55-60%. [IEA][AFDC][USDOT]

    Neither is a magic bullet. Both get their asses kicked by bicyles (and to a lesser degree, microcars). Both get better with increased passengers per vehicle. Both can be fueled with renewable energy for additional reduction. Both can be manufactured with renewable energy for additional reduction. Both take surprisingly equivalent amounts of raw resources and energy. EVs need batteries that are carbon-intensive under current practices, but rail needs large quantities of steel which is equally carbon-intensive under current practices.

    There are a ton of factors I can barely touch on here, so here’s a rapid-fire overview. Public transit offers unique advantages from an urbanist perspective and the liveability of cities [ST], but that’s objectively different from sustainability. The US has such low average ridership/occupancy that our busses have more emissions per passenger mile than our cars [AFDC1][AFDC2], and that was before the pandemic – it’s even worse now [NCBI]. Low ridership can be partly attributed to the incompatibility of American suburbs with public transit – which could be a major roadblock because 2/3rds of Americans own detatched homes [FRED], representing $52t [PRN] in middle-class wealth that they will likely defend with voting power. Climate solutions will need to maneuver around this voting bloc. I personally think individual EVs and intercity rail are complementary technologies – the more cheap (short-ranged) EVs are out there, the more people will lean on public transit for long trips. Heavy rail gets way better efficiency per vehicle mile than light rail or commuter rail and I have no clue why [APTA][ORNL], but I’m not as impressed by light rail as I expected to be. Since public transit and personal transport leverage different raw resources and face different challenges to adoption, we will achieve the most rapid decarbonization if we do both at the same time.

    TL;DR

    This is a huge, huge question, and anything short of a dissertation would fail to answer it objectively. My best answer is that the most effective solutions to climate change are diverse, engaging multiple technologies in parallel. EVs are a piece of the puzzle, but not a one-size-fits-all solution.
