    I'm a Lua fan. I adore using the language, both embedded and scripting, and it is incredibly easy to use.

    Lua's use of metamethods, tables, and functions to implement Object-Oriented design is probably one of the best I've seen.

    Just the fact that "Hello, World":sub(1, 9) is sugar for string.sub("Hello, World", 1, 9) is amazing, and a fantastic choice. Combine that with tables being weak references, and you have an instant way to use self in any OO class a user creates.

    However, pcall is anything but elegant or straightforward. Ensuring you've covered all relevant use-cases is painful, rather than something that just flows in the background of what you're trying to create. It's a pain point.

    Is this going to make using Tor or other means of anonymisation even more painful than it needs to be?

    Suppose that v3 then scores the user low. Would this tor user then have no option to access the website? This makes me uncomfortable.

    Bit of both, in my very limited experience. Though, the festivals around October tended to be somewhat Wiccan in nature, and they are well outside the average Australian culture.

    If people enjoy doing it, what's the problem," he says.

    I think there's something missing from their expert's analysis - the problems that come with Halloween, and Australian culture mixing.

    I've only seen trick-or-treaters the last three years.

    Every year, there have been multiple groups of teenagers who turn up at my un-decorated, unlit, house. If I answer the door, they threaten me with property destruction if I don't hand over chocolates and lollies that I don't have. If I don't answer the door, they proceed to the property destruction.

    Five smashed windows, in three years.

    The sense of entitlement given to people by this celebration is the problem I have with this holiday. Entitlement isn't something that belongs in Australian culture - we strive and work for everything, to a fault. There are problems with it. But entitlement isn't something I think many Australians welcome.

    It isn't that the holiday is American - it's that it's stereotypically American (sorry guys), believing you deserve something, without having done anything to get it.

    Small difference of experience - harvest festivals can be common in some farm areas, but they tend to just be bonfires and BBQs. But Halloween? That's a new thing, and god-awful, to be honest.

    We never had harvest festivals here

    Okay, this is a not-quite Brainfuck language.

    It's unoptimised, because I span it up in ~15mins. To prove you can.

    It takes input from the first commandline argument.

    I'm pretty sure it's portable C, but probably ISO, not ANSI.

    Plenty of style problems, like using int over size_t.

    I also expect it has a couple bugs.

    #include <stdio.h>

    void next() {
      if(pointer < STACK_LENGTH - 1)
        pointer++;
    }
    
    // Move unless we're at the top of the stack.
    void prev() {
      if(pointer > 0)
        pointer--;
    }
    
    void display() {
      // Woot, easy.
      printf("%c", stack[pointer]);
      // Make sure it prints.
      fflush(stdout);
    }
    
    // Read a single character.
    void readch() {
      int c = getchar();
      if(c != EOF)
        stack[pointer] = c;
        // Clear input buffer on some systems.
        while((c=getchar()!=EOF)){}
    }
    
    // The guts of our interpreter.
    void parse(char* program) {
      // No for loop, we need to be able to control
      // our position for our language to handle
      // looping.
      int pos = 0;
      int length = strlen(program);
    
      // Handle the current position in code.
      // Simple case switch because single char values.
      // Invalid characters are simply ignored.

    Every character is either a command, or ignored.

    • + Increments the current value of the stack cell. It won't increase beyond 255.
    • - Decrements the current value of the stack cell. It won't decrease beyond 0.
    • . Prints the current cell value as an ASCII character.
    • , Reads a single character from stdin, and replaces the cell with it's value. Characters with values greater than 255 are undefined behaviour.
    • [ Marks the beginning of a loop.
    • ] If the current cell is not 0, jump backwards to the previous [. Otherwise, continue processing.

    A three-person office was my ideal when I was working in a team.

    I had my direct overseer, and my more creative colleague within chair-sliding distance, but we all had our own desks, headphones, and a long list of things that needed to get done yesterday.

    I was able to get a serious amount of work done in that environment, especially as we were all comfortable with switching between working shoulder-to-shoulder or by ourselves without any help or supervision.


    However, when I was doing 3D modelling work for an architect, I would have adored a private office. So. Many. Interruptions. I was the only computer artist in the building, and everyone wanted their work, and expected me to pull a TV-ready rendering of their particular building out in ten minutes or so. Sorry, converting your CAD drawings to 3D takes a little bit more time, especially when you don't make the CAD drawing exact, and instead add an annotation.

    In that kind of space, I needed a door I could close, announcing to the world, "Sorry, I need to actually work hard right now."


    However, working remotely, or as an individual contractor, all I've needed is:

    • A comfortable chair
    • A decent desk
    • A laptop
    • A notebook
    • A whiteboard
    • A continuous supply of coffee

    Child-sized, ride on trains are somewhat expensive in my area, by which i mean $200-300.

    Dimensions are about 1200mm x 400mm x 420mm.

    However, I did managed to find an older one for $20 at a market.

    What you see here, is post-sanding (lead paint is awful), and half-way through re-painting (or the first layer of many).

    This one will probably go to my daughter, and yes, I said 'This one'. It's a really simple design. So, as I have several nieces, I've acquired the wood, and already had the tools, to make one for each of them for this Christmas, or that's the hope.

    I've just started rebuilding again, today.

    One of the core concepts I'm forcing myself to keep to, is that the computer should be able to be put together by just about anyone, and cheaply... So, as much as it pains me, I'm using an Arduino Uno, and a simple 2x16 matrix shield, with 5 useable buttons.

    The top row of the screen is used for output, the bottom row is input. To compensate for tiny screen, the software extends it with several extra buffers (8 currently). The first character of a row represents what position of input or output you're in, and you can scroll between each buffer. I may have to reduce the number of buffers, to provide enough memory for everything else.

    I'm a bit stuck on storage at the moment, as I really don't like using EEPROM because of stability issues long-term, and the Uno only has 512-1kb available. I could just add a flash chip, but then it becomes a difficult project for the average person. I could add a nodeMCU-flashed ESP01 (easy for most people to acquire), and use it's filesystem, over a serial connection, or add an SD card reader.

    But... Being myself, I'm trying to work out how to record/read cassette tapes (yay for nostalgia!), and if there are enough cassette systems around that the average person would find it easy enough to source.

    As for the inbuilt software - it needs a serious redesign. I'm looking at creating a bigger language for it, rather than a shell-style language, at the moment, but currently is has a handful of inbuilt commands: off (finish everything, become safe for power to be removed), ed (a simple line-editor), ec (echo), and pin (manipulate Arduino pins).

    There is something on my mind, and it's hurting me badly... But I just can't talk about it in any depth legally, which bugs me just as much.

    I'm depressed, and hurting.

    I didn't need a shit hand in life as well as being born into a chronic illness. One or the other, that's what I can handle, not both simultaneously.

    Not much cheers me up these days. Stuff like stupid programming languages and competition helps, but only so much.

    Being unable to get up and go for a walk just compounds everything. I tried harder the other day, and ended up collapsing in the middle of a mall.

    It would be easier if I could hate the people putting me through hell, but I can't. I can see each of their fears and desires, and understand why they're making their choices. I think their choices are crap, and making this worse for everyone, but I can understand why they would. That makes it worse.

    All of this makes every engagement with others, like lively debate here on Tildes, take an enormous effort, and I do find myself more irked than I should be at times.

    Spent the last two days with temporary paralysis... So trying to take things easy.

    Though, I'm already halfway through my weekend, and spent the day with my daughter, which was awesome.

    Warning: Incoming father-happy-rant.

    My little girl is two years old.

    She's getting really good at helping with cooking, and we made our traditional banana bread - and she can now say "banana bread", which is awesome.

    She also built a train track, and managed to assemble the crossing bridge herself, which is kinda impressive, it's fiddly.

    And finally, a bouncy ball was flying up and down the hallway between her grandfather, herself, and myself for most of the day. Accompanied by copious amounts of laughter.

    Though, she didn't want to do any gardening today, which was different, because she usually soaks all the plants with her own watering can. Probably because her grandfather made her stand around for an hour and help with potting plants a couple days ago, when all she wanted to do was go inside. I'll have to show her it doesn't have to be awful and boring again somehow.

    And she's developing a pretty good relationship with the dog. He's a red heeler, so fairly full of energy, and a little unpredictable because of the dingo, of which he has a fair streak. However, he usually does what I say, and he's learning to do what my daughter says. (She loves giving him a treat or pat.)

    The dog has a fairly strong protective instinct too, which is nice. He takes on a defence stance if a little distance appears between me and her.

    Wouldn't leave her alone with him ever, but nice to see she's starting to fear him less, and he's starting to obey her when she growls out a little, "Stop."

    End father-stuff.

    I'm probably not going to be able to stand up til midday tomorrow, the last day of my weekend... So probably watch some Brooklyn Nine Nine, and maybe a little more programming, though my brain is starting to go to fuzz.

    Be nice if I got either that thing or WiFi working on my homebrew computer, then I could start to use it for more stuff than just math.

    I'd be curious for an entry about Asperger's syndrome / ASD, they're not classified as mental illnesses or disabilities afaik, but to see how many other people here have it.

    They were in the DSM IV, the psychological diagnosis guidelines. When they released the next revision, DSM V, they were all rolled into 'Autism Spectrum Disorder', and the guidelines are much stricter about what counts, and what doesn't. It also means that disability is measured on a spectrum, meaning that these illnesses may be a disability, or may not, each individual will be different. However, they are still a mental illness, just a new name. ASD under DSM V, still a mental illness, but treating things a little more humanely, with a spectrum, acknowledging each individual has a few differences.
