Terraria 1.4

The final patch for Terraria, 1.4, came out last month. Thought I’d record my progress after a couple of weeks.

I’ve just playing on classic this time round. Think Empress and the Frost moon event is all that’s left.

Turns out I still cannot build anything that looks good.

But at least I’ve explored a bit on this large world

More ADS-B Random Stuff

Made some changes in the last couple of days. I setup a new antenna outside and switched to different software running on a Pi that automatically feeds ADS-B Exchange). Was really painless using their Pi image, just flashing a SD card and editing some text files.

The only problem I had was related to my router/internet connections constantly making requests from different IPs. But that was a simple fix on my router (once I understood the problem anyway).

I cannot directly compare stats with my old setup, but I have received around 2,000,000 messages in the last 24 hours and furthest contact was 360Km which is quite the improvement.

I’m still not 100% happy with the results, I would love to see more activity near Tullamarine and Avalon. I don’t think there is anything in the way, so it might just be a case of needing a bigger mast.

Some stats

If any of this is interesting, it’s really easy to get into. There are a variety of cheap dongles, windows/linux software, and pre-setup Pi distributions. There’s also plenty of information about building your antennas like this and this

Mucking around ADS-B

Been playing around with SDR using a RTLSDR dongle, and right now I’m receiving ADS-B from nearby aircraft.

Was shockingly easy to setup using ModeSDeco2 which even provides a local web interface (you would normally feed a site like ADS-B Exchange that combines the results from thousands of receivers around the world).

I’m using a simple dipole antenna stuck to a window with poor LOS to the sky (amazing planning), but I’d like to setup something a little better in the future and maybe feed too. So I thought I’d save some images of my current results to compare with later.

3D Printed Stencil

In an attempt to keep my rubbish bin from being (accidentally) taken by my neighbors, I tried to make a 3D printed stencil to make my unit number a little more obvious.

The first version was just a simple stencil. This probably worked the best, but required you to be careful of over-spray.

Then I tried to be clever and make a two tone number and add a shield to make it easier to apply. The idea was you did the background using the new stencil, and then drop in the original stencil and do the foreground. This actually fixed the problem of over-spray nicely. But the result didn’t look very good.

The main problem is that you aren’t going to get crisp lines as the 3D print is never going to be flush with the surface (enough that spray paint wont get under). I suspect the best way going forward would be to cut it out by hand on vinyl (Or make a vinyl cutter holder for my printer).

Overall, at least it’s pretty obvious which bin in mine now :-)

(Note: No STL as it barely works and I’m not happy with it).

Quick Tar Backup

I can never remember tar command line arguments to do a simple backup of the filesystem, so this time I’ll write it down.

mkdir -p /backups
cd /backups
tar -zcvpf /backups/img.tar.gz --directory=/ --exclude=proc --exclude=sys --exclude=dev/pts --exclude=backups .
python -m SimpleHTTPServer

# wget http://$SERVER_IP:8000/img.tar.gz

Intel NUC Spreadsheet

Trying to get my head around all the different NUCs and their performance/price.

Price was taken from Amazon (in USD) and performance from PassMark. Neither are very accurate, but should be adequate for an overview.

Wallabag + CapRover in 5m

Wallabag “is a self hostable application for saving web pages”

CapRover “is an extremely easy to use app/database deployment & web server manager”

This is a quick and dirty setup for testing Wallabag (without full database or redis, or email, etc).

5m setup

  1. Setup new app with persistent data enabled in CapRover
  2. In App Configs add the environmental variable SYMFONY__ENV__DOMAIN_NAME and set it to the full URL of where you want Wallabag. e.g. https://wallabag.rover.example.com
  3. Add two persistent directories ofr /var/www/wallabag/data/ and /var/www/wallabag/web/assets/images/
  4. In the deployment tab scroll down to method 4 and enter: FROM wallabag/wallabag and deploy
  5. In 30s Wallabag should be available at https://wallabag.rover.example.com
  6. Default login is wallabag / wallabag so you probably want to go change that

Example App Configs

Issues

  • No CSS or images: Need to make sure SYMFONY__ENV__DOMAIN_NAME points to the full URL including protocol. e.g. https://wallabag.rover.example.com
  • 502 error: Log into to server and check Docket logs. e.g. `
    • docker service logs srv-captain--wallabag --follow or
    • docker service ps srv-captain--wallabag --no-trunc

Download steam images

Little Python program to download your images from your Steam gallery.

For each file it just downloads the images by its id and attempts to include some meta data about the image in a separate json file. For example:

{"Id": 1474149818, "Game": "Crypt of the NecroDancer", "Desc": "Bat out of hell", "Url": "https://steamuserimages-a.akamaihd.net/ugc/974353539926239721/3591AA940A42F9217105C02EEA90190796893CED/"}

Code uses requests and has been tested with Python 3.7 on Windows.

Website back up

Website back up today after long period of down time.

I think I would like to go back to recording things I do.

Even if they are small and useless, I think it would be heathy for me.
