AC/DC is a VERY smart song, one of the reasons it’s my favorite lyrically in the show is that it’s so explicitly about electric trains and has multiple references to super interesting issues/traits with them. This doesn’t go into the broader electricity puns (which are shockingly versatile), just the ones most relevant to trains

“Feel my magnetism”

I’m still trying to figure out if this is an issue with remotely modern electric trains and motors, but I have heard a claim about a turn of the century New York Central S-motor (one of the very first mass produced electric locomotives!) basically “picking up and stealing” some tools left near the track this way and then dropping them when switched off.  Basically the whole “pulling in things with magnetism” has at least some real life precedent with trains.  

“AC/DC it’s okay by me/ I can switch and change my frequency”

This was perhaps the defining feature of the CC 40100 Electra’s helmet was based on.  Due to inconsistent electrification systems (due to early 20th century tech limits) it’s very common to have 2,3, even 4 voltage locomotives and EMUs since it’s cheaper and easier than replacing all that infrastructure.  Having both AC and DC compatibility is actually super old, the New Haven Railroad had one of the first AC-powered lines ever and the very first AC locomotives there had to be equipped for both it and the existing DC third rail in other sections.  But being able to run on multiple AC frequencies is much more recent, and the CC 40100 was an early example of it.  The Northeast Corridor in the US actually requires trains capable of running on THREE different AC voltages/frequencies, being able to “change your frequency” is an important requirement there (and in continental Europe)  

Basically, silly 70s-80s era bi allusions are just how electric trains are.  It’s so out there but so on the nose.  It’s probably the single smartest writing decision of the show because it works so well and talking train media otherwise NEVER talks about these aspects of electrification.  

“I can shock you, I can set you on fire”

The history of diesel and electric trains involves so, so much spontaneous combustion.  Exploding is almost exclusively a steam engine thing, but if they wanted to dramatically kill Electra or Greaseball or any of the Nationals, this is always an option and weirdly underused.  

“I can reach up and pluck down the lightning/watch the conductor, see the live wire”

Direct reference to overhead electrification and how pantographs are raised to make contact.   Also fun play on train conductor/electrical conductor, which is popular in trolley/train jokes.  This system is something almost exclusive to trains and part of why they are so established, efficient, widespread and convenient as electric vehicles.  They’re genuinely absurdly OP vs basically all other forms of traction since they don’t have to carry their own fuel/power supply and can have ridiculously high single-unit power since the only limit is how much capacity the power grid has (and how much can be practically used without wheelslip).  Due to their fixed paths they can run this way vs needing batteries and totally bypass the decades of density limits those had.  Even today batteries are not really practical as a main power source for anything bigger than commuter EMUs and switchers.  

(Trolleybuses are a thing and there’s been attempts at sticking pantographs on trucks… and I guess bumper cars technically count too lol) 

Shoutout to Stexico for having a very different chorus with somehow the exact same sentiment. 

“Macho/Hembra es mi conector” (Male/Female is my connector)

This is just a hilariously matter of fact statement about the electrical connections on AAR standard passenger engines and coaches, which I think Mexico uses since their rail system is so US-based but I could be wrong (privatization axed basically all their passenger services around the time Stexico came out and there’s very little even today).  The stuff about “with my switch I connect you” is also incredibly matter of fact because there’s usually a separate switch or dial to turn on head end power on locomotives.  

Electra is based on this very 70s bi stereotype/trope that lumps in the botanical definition of “bisexual” and makes characters “both male and female” in a way that’s inconsistently trans, GNC, and/or literally being 50/50 both in a way that doesn’t work that way in humans.  Velvet von Ragnar from Never Too Young to Die is almost IDENTICAL in this regard as another example.  But the hilarious thing is that it’s just… incredibly matter of fact and literal when applied to electric trains because so many of them are able to run on both AC and DC power because rail electrification is so messy and many of them are technically “both male and female” going off electrical connections.

Anyways, tangent aside

I do not know enough German to appreciate the intricacies of stuff like word choice or idioms in the translated lyrics but these ones are fun because they’re explicitly about overhead wires

“Steh unter Spannung”

I’ve seen the translation given as “I’m a live wire” but the more literal one seems to be “stand under tension/power/voltage” which I honestly like more no matter which one “Spannung” means here.  I know voltage is sometimes called “pressure” as in water pressure in English, which this might be a case of.  The allusion to voltage/power in overhead wire is obvious, but  literal catenary wire tension is also SO important specifically in rail electrification.  The wire has to be tight and straight enough to make proper contact with the pantograph (and getting the upwards pressure on those is also important).  Europe has mostly reasonably modern lines with adjustable weights to keep wire tension constant but the northeast US has HUGE issues with outdated systems with fixed wires that sag in the heat (then get snagged on pantographs and torn down) or snap in the cold when they shrink/expand.

“Ein Griff von mir” (A grip of mine)

“Holt den Blitz aus der Leitung,” (Takes the lightning out of the wire)

Also seems to be a direct reference to pantograph pressure/contact with overhead lines, similar to the English version of this line.  There’s a strong hand/arm association with pantographs in general due to their design, modern ones bend in arm-like ways and “touch” the wire in a very particular way.

Also this is probably just wild coincidence but “Griff” makes me laugh because Zaine Griff was the workshop Electra.

About the whole DOGE-will-rewrite Social Security's COBOL code in some new language thing, since this is a subject I have a whole lot of expertise in, a few anecdotes and thoughts.

Some time in the early 2000s I was doing some work with the real-time Java team at Sun, and there was a huge defense contractor with a peculiar query: Could we document how much memory an instance of every object type in the JDK uses? And could we guarantee that that number would never change, and definitely never grow, in any future Java version?

I remember discussing this with a few colleagues in a pub after work, and talking it through, and we all arrived at the conclusion that the only appropriate answer to this question as "Hell no." and that it was actually kind of idiotic.

Say you've written the code, in Java 5 or whatever, that launches nuclear missiles. You've tested it thoroughly, it's been reviewed six ways to Sunday because you do that with code like this (or you really, really, really should). It launches missiles and it works.

A new version of Java comes out. Do you upgrade? No, of course you don't upgrade. It works. Upgrading buys you nothing but risk. Why on earth would you? Because you could blow up the world 10 milliseconds sooner after someone pushes the button?

It launches fucking missiles. Of COURSE you don't do that.

There is zero reason to ever do that, and to anyone managing such a project who's a grownup, that's obvious. You don't fuck with things that work just to be one of the cool kids. Especially not when the thing that works is life-or-death (well, in this case, just death).

Another case: In the mid 2000s I trained some developers at Boeing. They had all this Fortran materials analysis code from the 70s - really fussy stuff, so you could do calculations like, if you have a sheet of composite material that is 2mm of this grade of aluminum bonded to that variety of fiberglass with this type of resin, and you drill a 1/2" hole in it, what is the effect on the strength of that airplane wing part when this amount of torque is applied at this angle. Really fussy, hard-to-do but when-it's-right-it's-right-forever stuff.

They were taking a very sane, smart approach to it: Leave the Fortran code as-is - it works, don't fuck with it - just build a nice, friendly graphical UI in Java on top of it that *calls* the code as-is.

We are used to broken software. The public has been trained to expect low quality as a fact of life - and the industry is rife with "agile" methodologies *designed* to churn out crappy software, because crappy guarantees a permanent ongoing revenue stream. It's an article of faith that everything is buggy (and if it isn't, we've got a process or two to sell you that will make it that way).

It's ironic. Every other form of engineering involves moving parts and things that wear and decay and break. Software has no moving parts. Done well, it should need *vastly* less maintenance than your car or the bridges it drives on. Software can actually be *finished* - it is heresy to say it, but given a well-defined problem, it is possible to actually *solve* it and move on, and not need to babysit or revisit it. In fact, most of our modern technological world is possible because of such solved problems. But we're trained to ignore that.

Yeah, COBOL is really long-in-the-tooth, and few people on earth want to code in it. But they have a working system with decades invested in addressing bugs and corner-cases.

Rewriting stuff - especially things that are life-and-death - in a fit of pique, or because of an emotional reaction to the technology used, or because you want to use the toys all the cool kids use - is idiotic. It's immaturity on display to the world.

Doing it with AI that's going to read COBOL code and churn something out in another language - so now you have code no human has read, written and understands - is simply insane. And the best software translators plus AI out there, is going to get things wrong - grievously wrong. And the odds of anyone figuring out what or where before it leads to disaster are low, never mind tracing that back to the original code and figuring out what that was supposed to do.

They probably should find their way off COBOL simply because people who know it and want to endure using it are hard to find and expensive. But you do that gradually, walling off parts of the system that work already and calling them from your language-du-jour, not building any new parts of the system in COBOL, and when you do need to make a change in one of those walled off sections, you migrate just that part.

We're basically talking about something like replacing the engine of a plane while it's flying. Now, do you do that a part-at-a-time with the ability to put back any piece where the new version fails? Or does it sound like a fine idea to vaporize the existing engine and beam in an object which a next-word-prediction software *says* is a contraption that does all the things the old engine did, and hope you don't crash?

The people involved in this have ZERO technical judgement.

kyr is a fascinating character to follow because it's been some time since ive read a book in which the protagonist was so just flatly incapable of connecting dots. the information is all there, the reader picks stuff up in bits and pieces and while still not having the full story, can glean most of the circumstances at any point in the book by, like, inference, but kyr has been trained since birth not to think too hard because thinking is how the enemy gets you, while ALSO having been taught from birth that she's better than everyone else, so when she uses as small a fraction of her brain as she can possibly get away with to produce one single conclusion, she's like yes! i have figured you all out, you hopeless traitors! you miserable hypocrites! you quislings! my superior intellect and i will always see through your lies! and then the conclusion she's come to is completely, patently incorrect

Researchers in the emerging field of spatial computing have developed a prototype augmented reality headset that uses holographic imaging to overlay full-color, 3D moving images on the lenses of what would appear to be an ordinary pair of glasses. Unlike the bulky headsets of present-day augmented reality systems, the new approach delivers a visually satisfying 3D viewing experience in a compact, comfortable, and attractive form factor suitable for all-day wear. “Our headset appears to the outside world just like an everyday pair of glasses, but what the wearer sees through the lenses is an enriched world overlaid with vibrant, full-color 3D computed imagery,” said Gordon Wetzstein, an associate professor of electrical engineering and an expert in the fast-emerging field of spatial computing. Wetzstein and a team of engineers introduce their device in a new paper in the journal Nature.

following up with that whole idea they got going on where dreams are just alternate realities ?? temporarily dismissing the fact that he has terribly vivid dreams of his own guilt + crimes , but we're thinking about happy dreams , maybe he's got a kid of his own , doing laundry or other mundane things. wakes up with a soft gasp , tears streaming from his eyes where he hadn't realized ...
