    So it’s not that the Volkswagen cheated on the emissions test. It’s that running the emissions test (as part of the building process) MODIFIED the car ITSELF to guzzle gas after the fact. We’re talking Transformers level of self modification. Manchurian Candidate sleeper agent levels of subterfuge.


  • From a software engineering view: Lots of rebuilding the wheel, now with Internet Explorer dependencies. Large tech firms are more and more bureaucratic rather than innovative. Startups slurp up VC funding for the next 200 or so unicorn investments. NVIDIA is THE ENTIRE S&P 500 at this rate with SERIOUS “Peak of Inflated Expectations” valuation. Elon Musk.

    All the while the majority of the job is fixing the mistakes of the past, of yourself and of some code monkey in 2003. There’s this theory that code replicates the structure of the design team. When that team spans an entire corporate hierarchy with SCRUM standups every 2.5 milliseconds, you wonder if you could do the equivalent of the ending of Office Space to the codebase.

    I’m sorry, I’m just… anyway, a sage piece of advice. For the love of all that is holy, write requirements BEFORE doing validation for Aerospace applications, and DO NOT OUTSOURCE THE REQUIREMENTS WRITING. That is all.


  • If you want any encouragement, one of the DDR regulars at the arcade was a totally non-college age woman who needed a hand brace due to some age-typical RSI, I presume. That is, I could only assume because she played up at the 13s (well near 9 footers and above) with dogged passion. I don’t even know how old she was because she had that cardio build, the kind you might find a Zumba enthusiast with. I’m not being ageist here: I’m more terrified of the 30, 35 year olds on the machines because I know their passion dictates their body and not the other way around. If you can’t take the high impacts on your joints for higher speeds, it’s always just fun to play the medium level charts and maybe even go for high scores. She didn’t need to go high and that was fine.

    If you wanna get back into the grove, YouTube has all of the charts of the better songs available. Just… load up Captain Jack (Grandale Mix), AFRONOVA, Dynamite Rave. Get back in the groove without a pad and just feel it come back! Unfortunately official cabinets have lost the rights to many of the older classic songs, but StepMania doesn’t care :). And if you do pick it back up and wanna chase the new stuff, well, you’re gonna have to dance for that privilege.


  • Actually my self esteem increased this past few years but I won’t pass up an ADHD infodump opportunity. DDR is, IMO, the most efficient path for videogamer enthusiasts to transition to healthy exercise.

    DanceDanceRevolution (DDR) is an arcade rhythm game that is certainly not dead, much to your surprise perhaps. The Japanese arcade scene is a whole, far more in depth iceberg to chip at, but trust me when I say Konami focusing on machines did not (only) mean pachinko machines, it also meant their multiple arcade rhythm games under the Bemani brand.

    I am not kidding when I say there was a DDR setup in my middle school in southern USA. I started a bit there, but I never got real dedicated gameplay until there was a new DDR cabinet installed at both Dave and Busters and a local arcade joint. Having access to a machine can be substituted by a home pad. Please, buy the L-TEK pad without the bar. Cheapest exercise equipment out there at 250 + shipping from Poland.

    You start off just browsing the songs in the roster until you find ones you like. There’s some token English licensed songs, but the bulk come from Konami original songs and a selection from the massive library that is the Rhythm Game Song Genre™. Most weebs get their beginnings from anime OPs and TouHou and Vocaloid, so if you have early YouTube nostalgia jump right into Bad Apple and Night of Nights. Later on you get addicted to the super high BPM (400+) techno mixes of the “Boss” songs (more on that later).

    So how is gameplay? Visually, four lanes of arrows travel from the bottom to the top, indicating when you have to step and in what direction on the four directional pads at your feet. You should learn quickly that keeping your feet on the arrows and never stepping in the center is the key to actual gameplay. The song’s patterns are designed to lead one into another. It’s far from dancing, but you transition from paying attention to each arrow to just stepping to the beat. You internalize patterns and you get better, right?

    But then, there’s a hurdle. Some songs demand you turn your hips and move your right foot on the left pad and vice versa. Difficulty is based on number 1 to 19, so you keep track that you can pass 11s, but not 12s. Each new song introduces new patterns in ordering and timing. Your old highest level becomes your warmups as you get better and better. You start to take a liking to faster, more complex rhythms like triplets, syncopated notes, and more sounds that a drummer doing prog rock would grok. One particular song has you galloping like a horse to Japanese festival music. If you know, you know.

    But there’s a catch, a limitation: your own body. Nearing difficulty 12 and 13, you’re doing the equivalent of a decent jog for around two minutes, right? You might start needing some time between songs to take a break and drink some water. At 14 and 15, you’re going for something called High Intensity Interval Training. That is, you go at your MAXIMUM SPEED for as long as the song demands you go. You don’t give up because that means losing and you paid for this arcade game, right? You push and push and sometimes fall over, but eventually you’re running ragged at 600 steps per minute begging that your life bar doesn’t sink anymore. You need more training. The next song is 440 BPM with 880 steps per minute.

    You want it. You want to play the harder songs in the difficulty ranking. You start to jog outside of the game on treadmills and otherwise. You put on the same heartrending songs and you find yourself sprinting desperately for 2 minute bursts because it’s impossible to stop while the song is playing. I’m running for almost an hour straight, and I get a head start at running progress because of my DDR experience! It pays off and you can play up to 15s, but there’s still 4 more levels until you get to 19. Over 4 years (at college, see?) I bike to the arcade, I play my heart out, I bike back. My blood pressure decreases, I breathe slower and deeper, and my snacking habits are at least counteracted. Best videogame of my life.

    Only downside? I can’t convince anyone outside of the rhythm gamers at the arcade that the music is good. The rhythms of those “Boss” songs are etched into your soul by the end. I can namedrop MAX 300 and everyone in the scene can practically play the song out in their heads. It’s literally a lifestyle hobby, and a rather healthy one at that.


  • I’ve got a Linux work server because VHDL simulations are hella expensive. I have to say that if your team isn’t willing to RTF-Man pages, you end up with a lot of cargo cult CLI processes. No crystalized knowledge or training, it’s hard to start up in it. It’s enough that requiring explicit Linux experience for new hires is preferable. Windows sadly has the familiarity benefit. And don’t get me started on the wacky custom solutions the IT set up circa 2002…



  • Your Only Move Is Hustle! YOMI Hustle for short. Turn based fighting game. If you’ve got a decent understanding of fighting games (Smash Bros specifically helps), you can play chess with a whole mess of moves. You can predict exactly what each move will do, as well as predict what happens for the opponents moves as well. No more failing inputs, since ever move is one click away. You get to learn high level concepts like frame advantage, oki, spacing, it’s all there with as little barrier of entry possible.
