What are tires so expensive?

Where can you buy 15mm and 28mm wheels for military vehicles? I looked around today and found several suppliers, but with outrageous prices at ~$2/tire. Langley Models have better prices, but still high. For some reason I had expected to be able to buy a 100 for $10.

Keiichi Matsuda's Hyper-Realty

Keiichi Matsuda has updated his 2010 haunting vision of an augmented reality with his new Hyper-Realty. Worth watching and, be advised, it is a horrible place.

"Flat" terrain feature example

I like adding features to an otherwise flat terrain board. This includes features like swales, outcroppings, or a bunch of logs. Anything that might get in the way of gameplay's terrain is put at the edges of the game board. Here is constructive set of photographs showing the progression of a flagstone and well terrain feature by Firedragon Games

How to start gaming a scenario?

I am working on a scenario and I am looking for advise. I have imagined a setting in the future where inadequate water supplies has lead to national governments and international corporations buying land in other countries to claim water rights. The water is then transported back home -- as water or as foods, eg wheat, rice, etc -- or sell it to the highest bidder. This lead to armed insurrection by the locals even though the water claims are legal. The insurrections have now devolved into multi-party factional/clan warfare. All factions have advanced military equipment (mechs!), but some factions have better supply lines and maintenance facilities than others.

The environment is harsh. Dust storms of national and global scale have made long distance wireless communications unreliable. So, despite the advanced equipment the factions continue to rely on scouting (human and autonomous drones) and runners to convey situation awareness and instructions between units. Even long range targeting and retargeting takes significant time, but once established is accurate. Some factions rely on well planned actions with strict adherence to the plan by the discrete units. Other factions rely on discrete units making local decisions stemming from the unit's overall purpose.

The scenario I am working on is a tanker truck needs to be driven to the coast (ie, off board) by its corporate owners. A rival faction wants to divert the trunk to its own facilities for local distribution (ie, driven off the other side of the board). It is a stalemate to have the trunk not reach either of these destinations before N rounds of play. It is a defeat for both sides if the tanker trunk is destroyed.

My initial plan was to use the Horizon Wars rules as I played an early edition of them from a few years ago. The rules are basic, but do make for a quick game. However, I am not wedded to them so am open to suggestions for other suitable rules.

My first question is how to start gaming a scenario? Is there an approach to determining the units needed? Or is it ad hoc, ie just play a game with a guess at unit composition and respond to the results? Or something else all together?

Update: The working document for this is at "A setting for near-future wargames."

Weekend workbench 2016-05-14

Finally made the cubby to hold my modeling tools, materials, and stuff. Still need to paint it, but that might happen in another life.

Meeting room geek lights

I have been giving more thought to the meeting room occupancy display. Right now I am considering what would be a minimal presentation. There are 2 reasons for this. The first is that the problem is not about showing details of who has reserved the room, but, instead, is the room free for squatting and, if so, for how long? The second problem is a technical one and that is the display device should run for weeks on a single battery charge. (I am assuming no mains electricity.)

So here is the new display.

⬤⬤⬤⬤⬤⬤⬤⬤⬤⬤⬤⬤

Each light, red and green, represents 10 minutes of time. The display shows a total of 2 hours of time. The above display indicates that the room is reserved for another 40 minutes, free for the following 60 minutes. and then occupied for at least 20 minutes -- it could be more, but the display can't indicate for how much more.

⬤⬤⬤⬤⬤⬤⬤⬤⬤⬤⬤⬤

Here the room is free for another 20 minutes, then reserved for 30 minutes, and the free again for at last 70 minutes.

The more I look at this the more I think that this is the solution.

The spotter stood still ...

The spotter stood still bracing himself against in the swirling sands of the desert winds. It was not sight but sound that caught his attention first. Once again, the people of the Rough needed to defend themselves against the Coppers. The Rough had only a ruined city and salvaged armaments to defend with. The Coppers had everything else ... except the will to never give up.

Meeting room occupancy project

We have an issue with staff not reserving meeting rooms. You know the situation, team High-Strung did reserve the room, but when they arrive they find that team Anarchist has squatted and are well into their arguments discussions. I don't include myself in the "we," by the way. I am happy to meet sitting on the floor with a big pad of paper between the participants. Anyway, it got me thinking about how technology can be used to exasperate this problem. For example, a display at the door to each meeting room that told folks if the room was reserved, for how much longer, who was using the room next, and lastly a list of reservations for today and tomorrow. Or, better yet, some ambient situation awareness device like Illumigami.

Before reinventing the wheel I did look around for a tool like this. What I found was a market of crazy, obese, gold plated implementations that actually cost money and often often lots of it. I don't object to making money from software, but not from something so simple as this, that is something that requires hardly more than a single web page. And so the development began.

The webapp is in its very early stages of development. I have just touched the surface of the Google Calendar API and its use within a HTML/JS page. At this point I am only concerned with the mechanics and so have made little attempt to make the UI useable. My goal with the UI is to have a tablet by each meeting room running a browser in "kiosk" mode and only showing the meeting room page. The page will show the events for a user who has authorized and selected a calendar.

If you want a side project and are interested in working on this with me to complete it the project is at https://github.com/andrewgilmartin/meeting-room-occupancy. A live version is running at http://andrewgilmartin.com/meetingroom/.

An unfortunate choice of title

There is a new dark ages set of wargame rules out called Blood Eagle. While I know that I play a game that represents an immoral, cruel, and bloody human activity, but to name a game after one of its more heinous acts were the warrior
would have their spine column exposed and then their ribs severed from the spine and pulled open (to resemble wings). Finally the lungs were exposed (and in some instances covered in salt) to complete the torture and lead to the death of the prisoner. (source)
is too much for me. I won't be playing that game.

"Splinters"

In a previous posting I wrote about using "splinters" to represent the kind of deadfall you find in the woods and bogs. I spent more energy that I care to admit settling on a source for the splinters: block planer shavings, chainsaw chunks, drill bit waste, ... In the end I used the dried up branches one drives over time and again on the driveway. A hand full of this material will spread out to a square foot of forest floor. Just split off a chunk, flatten it a few times with a hammer, and then pull it apart.

Preparing two more tables for May's Great Swamp Wargamers game night

Preparing two more tables tops for May's Great Swamp Wargamers game night. The table tops are 4'×3' hardboard glued and nailed on a framework made from 2"×1" pine boards. The edges are blue-taped to keep them clean until the terraforming is done. The terraforming is a simple process of

  1. Glue down any surface features. In this case, I am using "splinters" to give the appearance of deadfall found in a bog or forest floor.
  2. Paint the whole surface with an earth brown.
  3. Paint the surface features as needed. In this case a "wet" brown.
The remaining surface features are added in reverse order. That is, if you want daisies then put down the yellow flowers first, then add the grass, and finally add the dirt. The goal is that the items added first will absorb most of the glue so that when you get to step 8 what is on top will fall off.
  1. Using a spray bottle coat the entire surface with watered-down white glue -- about 1 part glue to 3 parts water. Use a spray bottle rather than a brush as it will apply a more even coating. A brush tends to leave ridges.
  2. Using a sieve apply a pattern of grass. When using Woodland Scenics's fine turf add some coarse turf to the sieve to slow the casting of the fine turf. If you don't do this then you tend to get mounds of turf rather than an even application. 
  3. Using a sieve apply to the remaining (non-grass) areas dirt. I use dirt from my yard that has been baked for an hour at 400° F to kill off the microbes. 
  4. When dry, turn the tabletop upside down and tap to remove excess grass and dirt.
  5. Finish with several applications of watered-down white glue or spray clear coat to fix the grass and dirt and make it resilient to playing on. I use a pressurized hand sprayer that is normally used for spraying insecticide. It can apply an even coat of the glue. The tabletop is noticeably wet after each spraying, but I do this outside on a warm day so that the glue drys before penetrating the hardboard.

Java 8 is not Java

Java 8 is not Java. Java 8 is a good tool. Java's shift towards being a functional language is unstoppable. Java, however, as a principled, strongly typed, object-oriented, imperative programing language is no more. I have heard the argument that as a developer I can stick with Java 7 syntax using -source 7, but this is not practical. Libraries will evolve to use use functional practices. Old bugs will only be fixed in these evolved libraries. As functional practices becomes ever more rooted in the libraries their use from Java 7's syntax will become ever more cumbersome and perhaps impossible. If you want to continue developing in Java then you and your team will have to evolve with it.

So these days I am thinking ever more about what language to move to. I think the perspective of my employer would be to remain with a language targeting the JVM. I haven't asked, but I know well enough its conservative approach to solutions. The software architect in me would like to pick a language that is more aligned with a fail fast approach to service runtime and its corollary of needing to start fast.

Lots of folks at this week's O'Reilly Software Architecture conference in NYC are favoring Go (commonly called "golang" to make the conversation clearer and searchable). That it compiles to a binary (and even a statically linked binary) for direct execution on the host is a significant boost to start fast. Starting slow would be your architect's fault: Too much in-process preparation and not enough just in time initialization or not enough externalization of functionality into a service. I will look at Go and its libraries. I do worry that is the new black, like Ruby was several years ago.

2D6 percentage dice

Sometime ago I found online a discussion about using D6 dice to simulate percentage dice. Unfortunately, I did not keep a link to the discussion. Anyway, I wanted to add my 2 cents and so here it is. You can use 2 D6 to compute a value over the 1 to 100 percentage range. The two dice, A and B, are treated as base 6 1st and 2nd place values. The range is 0 to 35, ie, ( A - 1 ) * 6 + ( B - 1 ), and so the percentage step is roughly 2.7%. This seems like enough granularity for most games using percentage dice. The lookup table is

Fuck you Wizards of the Coast! Let me play Magic!

I want to practice Magic the Gathering and so using one of Wizards of the Coast's applications seems like a good way to proceed. Now remember that Magic is a card game, let me spell that out C A R D G A M E, and so one would presume that the software is not too hard to write and it would have minimal requirements of the host machine. "No fucking way," says Wizards of the Coast (aka Hasbro) 'cause we are all about you buying more stuff. So, to be clear, ...

"No, you can't use that 2012 Windows 7 machine because you don't have enough graphics RAM."

"No, you can't use that 2014 MacBook Pro because we don't support Steam for OS X."

"No, you can't use that same 2014 MacBook Pro with a Windows virtual machine either you looser."

"No, you can't use that iPad Mini 1 because, well, we hate you."

Dear Wizards of the Coast, I want to play your game. I want to buy your cards. I will even buy your card sleeves. And buy them all again every 3 months. But I am not buying another computer to play a fucking card game!

The Internet is composed of unspoken inner thoughts

Weekend Workbench 2016-03-19

This weekend's workbench was moving the workbench. Well, what I was using was not a workbench but the end of a large table that is also used for gaming, the kids homework, boardgames, and other activities that need to spread out. I had intended to move to a small table that I bought at Ikea a few months ago, but decided it would require that I add a back and sides and shelves and ... well it was beginning to become a bureau. I not did want to put that much time into that kind of project right now.

Next to my computer desk is a second computer desk. This had an old Mac Mini that the kids used to play on and do some homework with. Since they got Chromebooks, however, they really have not touched it. Its last use was for Minecraft, but even that obsession has past. So, I decided to repurpose the desk for modeling.

I packed up all the computer equipment, including two ancient x86 towers, added overhead lighting, and moved over the modeling stuff. I am glad I made this choice. The table is 6' x 2.5'ish so there is plenty of width and just enough depth. I have a couple of Ikea flat files for holding my unpainted figure, modeling bits, and infrequently used tools so I have a good amount of storage. I will likely build something akin to Linn/Darbin Orvar's small parts organizer caddy in the coming months.

So, back to painting those 6mm Vikings and Anglo-Saxons. Which, I have to admit, I might never finish. They are just not that much fun to paint. At this point I am thinking that for 6mm figures I will send them out to be painted. At 30¢ to 80¢ per figure a few hundred would be $100 to $200. Well worth the cost.

Staples and large format prints

A reminder that Staples prints large format (eg 36"×48"), black and white, engineering drawings at a very reasonable cost. They is currently having a sale on printing 24"×36" engineering drawings for $3.59. So, the next time you want a map of your dungeon crawl, space combat40K coloring poster, or you have the need to Feel the Bern (source) get it printed at Staples Copy & Print.
