Elite Dangerous? Mostly Loading, Mostly Crashing, Mostly Irritating, Mostly Lonely 2

  Elite: Dangerous is an ambitious game, and on the whole is very well done. Though I would say it has been and continues to be plagued with a number of unfortunate gameplay killing problems, I expect that most of them will be taken care of post-haste. Games generally have two major problems, both are the game designer/programmer/producers fault: Buggy Client/Server The first kind of problem is the buggy client or server, but this is a fault which we can’t really hold against them, because it’s not like there is some cadre of developers twisting their mustaches and laughing about how often the client or server goes down or disconnects. It’s irritating, but generally the pleasure gained playing the game while it’s working can offset this problem. There is also the issue of being an early adopter of a game, the sooner you get in, the more money/power/respect you’ll build up in the game so coping with the growing pains of the client and server as well as the game has its benefits. Shitty Gameplay The other problem a game can have is shitty gameplay, which is a rather broad category which spans from irritating mechanics all the way up to “you’ve got to be fucking kidding me.” While Elite:Dangerous seems to have minimized any serious fun killers, there are a few mechanics which just piss you off to no end. When you couple these issues with the fact that if rand(10) < 5, the server randomly disconnects, or crashes, especially while in SuperCruise, HyperDrive, […]


Deconstructing Harry Potter

Harry Potter is probably one of the most well known fictional characters in history. I don’t say that lightly, and perhaps it’s just an accident of the times, or perhaps it’s because he really is awesome. I struggle with saying this: I hate Harry Potter. I think he is quite simply the stupidest person in all of fiction. I love the Harry Potter books, I have read them many times. I love all of the characters. All of them except Harry. Harry is the perfect example of the non-hero. He never really does anything worthwhile of his own accord. He is constantly in situations where he wins by default, because he is the protagonist, and because he is destined to win, but never because of any innate talent. In fact, the only talent he has is the ability to ride a broom. That is: he’s a jock. All of Harry Potter’s popularity, success, and his very life comes from those things done by others for which he benefits. He benefits from his mother’s sacrifice, his father’s and Dumbledore’s ingenuity, Hermiones fastidious studying and so on. Harry Potter is the most active passive hero ever. Throughout the book series we learn about his father, who is a genius and a jock. I mean he figures out how to map Hogwarts, how to transfigure himself, and apparently makes enough money to keep Harry knee deep in chocolate frogs for at least 7 years of school. We learn about Snape, and via his potions textbook, how clever he […]

ANTLR4: So awesome it makes Java look good

I have been trying to write my own programming language off and on for about 5 years now. That doesn’t mean I have spent 5 years on a single project. Only that I have been toying with the idea and educating myself for that amount of time. Writing your own language is kind of the Holy Grail of computer science. Well, writing a language that is actually useful. Over the years, my experience in Ruby, PHP, C/C++, Python and even LISP, has informed my idea of what a good language would look like. Note I didn’t say perfect language. There is no such thing. I have come to believe that all languages are good in some way or another, and bad in other ways. Emotionally I like Ruby, and I like C. The elegant syntax of Ruby makes you happy to program, while the Do-Anything attitude of C makes it the ultimate language. I have been looking at Java( due to it’s cross platform nature ) and have to say at first I hated it. Now I hate it less. The number one reason I hate it less is ANTLR. I love the code generated by ANTLR because it looks like code that a human being would actually write. It’s very dense, but it’s alive. It’s hackish and clever. I have been following along the book The Definitive ANTLR4 Reference. This is a first time for me. Normally I, quite wrongly, just jump in and get it done. This time I am going to RTFM. […]


HTML5 Canvas: Smooth, variable width lines with transparency. 2

When making a drawing app with HTML5 canvas, you might come up against the problem of making a smooth, variable width line. Eventually you might find that you can make several calls to ctx.quadraticCurveTo(x,y,xc,yc) and get some kind of effect. If you stroke every 2 or 3 points, then as long as the line width is very small, you won’t notice the jaggedness. Unfortunately, if you try to do this with semi-transparent lines, the effect is truly horrible. To solve this problem, instead of drawing lines, I simply draw very thin shapes, and fill them with a color. This allows for 1) variable thickness and 2) nice transparency. Variable transparency is a problem I haven’t quite figured out yet. It may require composing the shape from individual pixels, which is simply too slow, especially in IE. What I am writing is a drawing App that works with the Wacom Web Plugin, and therefore varies line thickness based on pressure. I would like to vary opacity too, but this seems problematic right now. A solution that may be possible is to fill the shape with a complex gradient, if it is possible to create semi-transparent stops. Here is an image of what the program does so far:   Each line is actually a full shape, with varying degrees of opacity. Thickness and thinness is accomplished with pen pressure from the Wacom Intuous5 tablet. As the line is drawn, a temporary line is shown to the user, when they lift the pen, that line disappears, and a […]

Jay n’ Mike’s Rules of Acquisition

My programming partner and I have been working for quite some time on some large projects, and we have come up with a basic list of rules that apply to startup computer businesses, from software development to software sales. You have to pay – Nothing in life is free, someone is always paying for it, in time, energy, and or money.  Never-Ever do anything for free, because when it’s free, you’re the one paying for it. That doesn’t mean you have to charge money for things, there are many forms of currency, favors, endorsements, contributions, and forgiveness for mistakes and lateness are all ways of getting compensated for going the extra mile. No funny stuff- This is also what we call Jay n’ Mike’s Razor, similar to Occam’s Razor, where the simplest solution is usually the correct one, this rule states that the simplest and most direct route to a solution is the most maintainable, stable, and testable. Arcane, convoluted, esoteric systems are a hassle. This applies to development as well as business.This rule is akin to the KISS principle, keep it simple stupid, but is more precise in its application, that is, it is not so much about keeping it simple, somethings just can’t be made simpler than they are, it’s about keeping things explicit. While the No funny stuff rule may seem simple and obvious, there are some important conflicts, for instance, while some meta-programming is permitted, it almost always violates the No funny stuff rule. Some optimizations in code, like managing several […]

Qt C++: Threaded Communication with Artema Hybrid on Linux

Communicating with an Artema Hybrid CC Payment device is actually deceptively simple. I’ve written an application what uses a webkit widget exclusively for the UI display, and so I hook into the Javascript to provide some extra functionality to the app, in this case, reading and writing to/from the Artema Hybrid device. The documentation that I received was in German exclusively, so this took a bit of work to get going, but once you have it down it’s very easy. The device is connected via it’s POS connection Serial->RJ45 connection to a Serial->USB (FTDI chipset) converter that gets plugged into a usb port. You use the standard open, read, write and close functions. The Artema Hybrid constantly communicates with your system, so you’ll need to create a QThread to run in the background reading from the device once every second. The Artema Hybrid will send you an ENQ (0×05) and you need to respond with either an ACK (0×06) or an STX (0×02). With the way that I have it set up, the c++ code does the absolute minimum required which is it reads from the device and emits a dataRead() signal which is connected in Javascript. If I read ENQ, then I emit dataRead(“ENQ”). and in the Javascript function that is connected to the dataRead() signal, I see if the string passed up == ENQ. In the javascript, I have an array of data to write to the device, if that array is empty, I just write back to the Device ACK, otherwise, I […]

A Letter to the Creators of EVE

A Response to CCP Hellmar’s Letter. The estrangement from CCP that many of you have been feeling of late is my fault, and for that I am truly sorry. There are many contributing factors, but in the end it is I who must shoulder the responsibility for much of what has happened. I appreciate both the sentiment and the spin, as well as the effort you are putting forward, to be honest I doubt many other game companies would bother to write the letter you’re writing but let’s be honest, the problems with EVE and with CCP are endemic, and asking us to swallow this guilt trip is not coming off as humble as you’d think. I mean saying that you are responsible for the the current state of EVE is like saying Lee Harvey Oswald really shot JFK, sure, that’s the official story, but no one really believes it. I was impatient when I should have been cautious, defiant when I should have been conciliatory and arrogant when I should have been humble. No, You were greedy. We aren’t children, well most of us aren’t. A few of us have lived long enough, and participated in business long enough to recognize zealous hubris from gluttonous greed. You got greedy and you fucked up. You started to look at us like we were just dollar signs, just consumers. …growing the company to 600 people, increasing our subscriber count beyond that of the population of Iceland and on and on, one resounding success after the next […]

Fear and Loathing On Tranquility 2

There’s a general tendency in the world to cruelty and sadism, a kind of malaise that affects the hearts and minds of those who for all intents and purposes appear to be normal human beings. You never know who they are in your daily life, but they exist, some are called sociopaths, others psychopaths, but I tend to think that there is something more too it, a kind of awful yearning in the human heart to burn everything in your sight. But more importantly, to burn it alive. There’s a river deep in the soul of man from which springs eternally all the goodness that could ever be, and next to that river is a textile factory, weaving a cloth of iniquity and ejecting the raw sewage of its manufacture into said river. The toilets also flush there, at least from the smell. If there is only one truth you ever learn in this life is that most people you meet, even if they aren’t hurting you now, will probably not think twice at hurting in the future if they ever get the chance. This unfortunate reality dawns on most of us a little too late. Thus enters the game of EVE Online. The Sandbox. EVE Online is the sci-fi cesspool of all the worlds most childish and sadistic and hopeful and nerdy and intelligent and dimwitted. It is a melting pot of every type of player from every type of game somehow all living in the same space, something that CCP prides themselves on. […]

Rails 3 – PHP Style Global Variables, $_SESSION, $_GET, $_POST in the models, and everywhere.

PHP Globals in Rails 3 So, as part of my slow descent into hell for even showing this stuff, I thought I would make a quick and dirty post about getting PHP like globals into your models in Rails. I wrote a longer article about globals in the model in rails which you can check out for some other options. def some_before_filter $_SESSION = session $_GET = request.GET $_POST = request.POST $GLOBALS = {} end Yeah, that simple. When it comes to globals, the ruby and rails community is kind of like the child of a former Nazi sympathizer who got off the hook at Nuremburg. Yeah, they’re related, but they just don’t want to have anything to do with them, and if you remind them of the connection they get really angry.

Apache2/MySQL on Ubuntu Configuration

Once you’ve installed apache2 and mysql on your server, you might want to try these configuration changes to make it perform a bit better: In /etc/mysql/my.cnf key_buffer = 16K max_allowed_packet = 1M thread_stack = 64K table_cache = 4 sort_buffer = 64K net_buffer_length = 2K And in Apache2′s config, /etc/apache2/apache2.conf, find the section for MPM prefork if yo have it and: StartServers 1 MinSpareServers 3 MaxSpareServers 6 ServerLimit 24 MaxClients 24 MaxRequestsPerChild 3000 The above are just some things to try if you encounter a situation where apache is using too much memory, or the same for mysqld.
