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:

• Canopus and refinements Solomani sectors by Randy Dorman
• Placeholders for five sectors in K'kree space by Jim Kundert: Xaagr, Raakaan, Uuk, Bar'kakr, Nuughu
• Work on several sectors by WG Zeist, including Ahkiweahi', Ghoekhnael, Zao Kfeng Ig Grilokh, Kfazz Ghik
• Knoellighz by The Pakkrat
• Work on the Orion OB1 Association by WG Zeist
• Hiver updates and fixes by Mark Humphreys
• Zho pop fixes by Jim Kundert

Data Overview 2017

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.

Visualizations:

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:

T5SS

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:

• Canopus, Aldebaran, Neworld, Langere - by Randy Dorman
• Tienspevnekr - by Jim Kundert
• Gashikan and Trenchans - by Jeff Zeitlin

So here's the overview with unofficial data dimmed:
