A programmer with an interest in transit, making music, and building things of all types.

I have dysgraphia which makes writing difficult for me. I hope you can figure out what I mean despite my issues.

  • Abuse. I don’t agreewithfree speach in all things. I doupt anyone does. I don’t want to see constant (to the point of only) ads for vbucks. I don’t want threats to my person. There are a few other things like that, that I think we all agree on., I then have a personal list of things like porn or swearing that iidon’t want to see but some of you do. Where to draw theelineethus isn’t clear but there is one.











  • A terminal is something like a DEC model Vt220, or IBM 3270. These are physical machines with a keyboard, and a display. Most often the display was a CRT, but some were just a printer, I supposed some must have had a LCD but I’ve never seen one. A few did have a mouse, but that was rare. They might look like a computer, but they do not have a CPU (or they do but the CPU is very under powered). The point is you can have 100 cheap (cheap as in 4x the cost of a modern PC, without factoring in inflation) terminals connecting to an expensive powerful computer (expensive as in millions of not inflation adjusted dollars, powerful as in a modern smart phone is faster by nearly any measure). Every terminal had some special commands that programs could use to do something more fancy than plain text, but different ones had different abilities.

    These days a powerful PC is cheaper than any terminal could be and vastly more powerful than those old computers, so it doesn’t make sense to have one except as a collectors item. However terminals themselves did leave a useful of program design. Most command line programs know how to control a terminal to do some pretty printing. Thus we often use terminal emulators which let our computer pretend to be one of those old terminals. The DEC vt100 for whatever reason ends up being the most commonly emulated terminal when someone says terminal emulator - there really was a model vt100 terminal at one time.

    Note that a web browser counts as a terminal emulator by the above definition. Nobody thinks of them that way, but they fit.

    Rubber are a nickel and dime feature because that is one of the few areas where dealers can make money. Most people walk into the dealer knowing the cost the dealer is paying for the car, and they are determined not to pay a penny more. this leaves zero money for the dealer to pay for the lights, building, and other overhead, not to mention a fair salary for the salesman (apologies to the tiny minority of females in car sales) who sold it.

    If everyone (not just you!) would go to buy a new car with the plan to get a fair win-win deal for everyone then the dealer wouldn’t have to find all these ways to nickel and dime you on extras.


  • Docker gives you a few different things which might or might not matter. Note that all of the following can be gotten in ways other than docker as well. Sometimes those ways are better, but often what is better is just opinion. There are downsides to some of the following as well that may not be obvious.

    With docker you can take a container and roll it out to 100s of different machines quickly. this is great for scaling if your application can scale that way.

    With docker you can run two services on the same machine that use incompatible versions of some library. It isn’t unheard of to try to upgrade your system and discover something you need isn’t compatible with the new library, while something else you need to upgrade needs the new library. Docker means each service gets separate copies of what is needs and when you upgrade one you can leave the other behind.

    With docker you can test an upgrade and then when you roll it out know you are rolling out the same thing everywhere.

    With docker you can move a service from one machine to a different one somewhat easily if needed. Either to save money on servers, or to use more as more power is needed. Since the service itself is in a docker you can just start the container elsewhere and change pointers.

    With docker if someone does manage to break into a container they probably cannot break into other containers running on the same system. (if this is a worry you need to do more risk assessment, they can still do plenty of damage)


  • The duolingo format was never popular with polyglots. The game format makes it easy to feel like you did something which is a great thing, but the is the only pro people who have learned multiple languages find with it.

    There is a lot of debate about what the best way to start is, but all agree that you need to interact with the real language in real world type settings (watching a movie in the language with subtitles is real world, though you need to make an effort to listen not just read!) They also agree that time is important, you need to study at least an hour every day to make progress.
