Recent Site Outage

A few days ago I pushed an update to the site. Although everything tested fine locally, apparently one of the included changes introduced a serious bug impacting performance. I haven't tracked down the cause yet, but I've rolled back the code which seems to have helped:

The black line spiking up is CPU usage. Normally it's around 2 minutes per hour (i.e. the host machine is actually sitting idle most of the time). For the last few days it's been around 50 minutes per hour - meaning it's been spinning its wheels like mad. And when it's like that, every request is extremely slow - minutes instead of milliseconds.

Sorry about that. :(

It may take some time to track down, and the odds are high that I'll push a bad release or two out while trying to bisect down to the exact bug - and it takes a few minutes of monitoring to even notice that it's occurring. So please be patient.



Data Overview 2017

It's that time of year when look at the current state of the Traveller Map and the changes that happened over the last 12 months. (Past Overviews)

General Updates

Following the passing of Don McKinney just over a year ago a lot of the momentum for the Traveller 5 Second Survey project was lost, but contributors to the site kept iterating on and providing new data. Some of the updates include:

Milieu Support

To assist in the development of the new "Galaxiad" setting set in the far, far future of M1900 I added milieu support. Several developers jumped on the bandwagon to adapt published sectors or placeholders for borders from various eras in the history of Charted Space. The data in most of the milieu is pretty sparse as yet.

I added a few new visualizations, as well as experimental UI to control them.

You can see the Empress Wave bearing down on charted space circa M1105:

And turn on visualizing Jump-1 mains - here the Vilani Main:

Or see depictions of stellar data to look for anomalies:

Finally, towards the end of 2016 we rebooted the Traveller 5 Second Survey effort. Several additional sectors have been brought "In Review" and we've begun to do more cleanup of the data, looking for glitches that have crept it and making progress on the work Don started:

Now in review, joining the T5SS data set:
So here's the overview with unofficial data dimmed:

Happy New Year!



In Review: Cano, Alde, Newo, Lang, Tien, Gash and Tren

Similar post made over on Citizens of the Imperium.

After a long break, I can announce some progress on the T5SS effort.

Marc continues to have a high level mandate to create a stable, consistent data set for the OTU as a tool for authors. This allows him (and others) to e.g. understand the impact of the Wave on charted space from 1105 to 1900, or figure how how the Vilani formed the Ziru Sirka along J-1 mains thousands of years earlier.

The canonical data set resides in Marc's hands. I've spent time over the last few weeks reconciling it with changes made by DonM between October and December 2015 that never made it back to Marc, as well as a handful of corrections applied directly to the site. We now once again have a consistent basis for the T5SS, and I can resuming make updates to the site from it.

Over the last few days I tackled three big additions to the T5SS data set. These are all now considered "In Review":

Feedback should be directed to the COTI T5SS thread.



Milieu Support

Traveller uses the term milieu (plural: milieux) to describe a particular setting or era. Milieu include the Golden Age (described in Classic Traveller and Mongoose Traveller, circa 1105), the Rebellion (described in MegaTraveller, circa 1120), the New Era (circa 1202, 1248), Milieu 0 (from T4, from 0 through 300), Interstellar Wars (from GURPS Traveller: Interstellar Wars), and even alternate settings such as the GURPS Traveller alternate timeline (a.k.a. "Lorenverse").

The Traveller Map defaults to the Golden Age (circa 1105), which is the focus of the T5SS effort. It now offers experimental support for other Milieu. To enable it:

  1. Go to the Settings menu (gear)
  2. Check "Enable Experiments"
  3. A new Experiments menu (flask) will appear
  4. From that menu, select a milieu:

You can play with some other experimental features that are there.

The available milieux are currently:

  • The Interstellar Wars - featuring only the Solomani Rim as depicted in GURPS Traveller: Interstellar Wars by Drye, Wiseman and Zeigler. Data adapted by adapted by Dom Mooney
  • 990 - Solomani Rim War. Features the data from Gateway to Destiny (the Gateway Domain) which is all I have handy for that time period, from Gateway to PDF.
  • 1105 - this is the default, with data from T5SS and unofficial contributions
  • 1900 - the Galaxiad setting. This is a work in progress with just the Spinward Marches and parts of Gvurrdon, c/o Rob Eaglestone.
Submission of data to flesh out these milieux or start others are welcome!

The API docs are updated to include milieu parameters where supported. Note that the values currently supported are: IW, M990, M1900 - and leave the param off for the default. If data is not present for a sector in a given milieu you'll get 404 Not Found errors.

When generating images, placeholder markers (*) will be shown for systems where default (1105) data has a system.

There are some caveats with the experimental support:

  • Search does not consider milieux, so the results won't match what you see.
  • Routes do not consider milieux so those results will also be off, too
There are a few more bugs noted in the issue tracker. Additional bug reports welcome.



Data Overview 2016

Once a year we look at the current state of the Traveller Map and the changes that happened over the last 12 months.  (Past Overviews)

This year starts on a somber note, having lost some luminaries in the Traveller community, most notably Don McKinney who was heading up the Traveller 5 Second Survey project to produce an official dataset for the OTU. Don was responsible for sending me updates for the official data used on the map, and shepherding data through a review process. The process included dusting off fan-favorite sectors previously considered apocryphal, reviewing submissions by other Traveller writers and referees, and getting feedback after making the preliminary data available via the map. Don will be missed, and the T5SS process will definitely take a bit to get back on track.

Thanks primarily to Don's efforts, 2015 was a year of tremendous growth and refinement in the official dataset. And momentum was started that has continued since his death. I've delayed posting this because there is a lot of work coming down the pipeline, and it's tempting to wait for it to land. But let's get to the picture - or pictures this time, of what's in there now:

Data Overview
The usual round-up of changes in 2015:
It's useful to toggle the "Dim Unofficial Data" setting to see what's in the T5SS review pipeline:
Unofficial Data Dimmed
I've also added a few overlay options to visualize stuff for the T5SS reviewers. Droyne/Chirper world locations:
Droyne Worlds ★ / Chirper Worlds ☆
Populations - the area of the circle is proportional to the population of the world, so you can only really see worlds with 10 billion or more sophonts. The large circle to Trailing is the (possibly apocryphal) Nooq Sphere, with a larger population than many entire sectors. This also shows where unofficial data may need some work:
Population Overlay
And here's an overlay highlighting world Importance (a T5 stat derived from the UWP):

One last picture, that compares coverage versus the area from the original Imperium poster:

I'm sure there's more data to come soon, but I need to publish this before January runs out.

Happy 2016!
