Hi and welcome to my site.
This site is broken into 2 parts.
The Tech Journal
which is my adventures in technology and is the most active part of the site.
The other half is the Outdoor Journal
which is all about my outdoors hobbies.
This main page will always show the most recent post from each half of the site. Click the links above to see more posts from the Tech or Outdoor halves of the site

I've been a huge fan of cloudtrail since it was launched. It provides one of the best tools available to see what is happening in your environment. Unfortunately AWS by default doesn't provide a dashboard or a way to actually process these logs. The viewer they give you is almost useless.
Hence creating Traildash2, a serverless application that takes your cloudtrail logs and pushes them into AWS ElasticSearch and provides a nice dashboard to show off all your handy work!
The default TrailDash2 dashboard
The source code, cloudformation templates for deployment, documentation and deployment steps can all be found over at the github site https://github.com/adcreare/traildash2
The basics of the application is fairly simple. Attach a lambda trigger to the S3 bucket which contains the cloudtrail files. Every-time a new file arrives the lambda will trigger. Each file will be received from S3 and pushed into the elastic search cluster. The custom dashboard then allows that data to be displayed and searched in a more useful way.
TrailDash2 comes from a tool called TrailDash developed by the team from AppliedTrust https://github.com/AppliedTrust/traildash
. Unfortunately they have ended the life of their tool and creating your own dashboard from scratch isn't that straight forward.
Longer term I have plans for the lambda function to support alerting on certain event types, probably into an SNS topic. This would provide the administrator a bunch of alarms for certain kinds of events.
Its open source, so feel free to modify and extend the application, I will happily accept pull requests as well.

We had wonderful weather for our walk, not a cloud in the sky but also not too hot. Almost prefect walking weather.
I had arranged to meet everyone at the Maple Grove car park, which is just back from the Scenic Railway and normally doesn't have many cars in it. It's also close to the end of the Furber steps which was the planned walk out route.
From the car park we walked along the Prince Henry cliff walk to Echo Point and then onto the start of The Giant Staircase. This was probably a couple of KMs and took us around 30 minutes to complete. The descent down the Giant Staircase was straight forward and done without incident while enjoying some of the great views over the Jamison valley.
The Giant Staircase sounds worse than it really is. Yes it's steep and narrow, but it's not that long. The descent for us took around 20 minutes and that was with a lot of traffic. The climb back up would take longer. I'd allow 45 minutes to an hour. Less if you're really fit!
Once at the bottom of the stairs we started out for the Scenic Railway which is around 3KM from the base of the Giant Staircase.
We stopped for lunch in a beautiful spot at the base of the Katoomba falls. A short distance before the base of the Scenic Railway. We even celebrated the birthday of one of the group members with cake and all! Much to his surprise.
From the base of the Scenic Railway we walked along the new(ish) boardwalk until the dirt track turn off to Ruined Castle, Golden Stairs and Landslide.
The first part of the track before the Landslide is straight forward. However, when the main fork is reached the lower one needs to be taken or you'll end up against the rock face near Malita Point. The track also cut directly through one of the coal seams in the area. The Scenic Railway was in fact built to service the mines down in the valley long before it became the tourist attraction it is now. When the mines closed up, the railway remained and continues to operate to this day. The base of the railway now has lots of exhibits and signs talking about the old mining days. If you've never been down that way before its certainly worth a look.
I also found what looks like an old mine air shaft between the Landslide and the Golden Stairs. I grabbed the torch and had a quick look in the entrance and found the cutting was almost a prefect rectangle continuing dead straight into the rock for as far as I could see. I would love to know more details if anyone out there has some knowledge about what it is and what shafts in the mountain it connects to.
I should add here just in case someone is dumb enough to get silly ideas. Mine shafts are not something that should be explored. They can be highly unstable and a real death trap for the inexperienced.
Next we came to the Landslide, which I have to say isn't the nicest of walking. Its a lot of small loose rocks which is all too easy to slip on. The path over the rock pile is sign posted with arrows and yellow panted stakes in the ground however inexperienced walkers do need to be careful, its easy to miss a few.
Once we were past the landslide its mostly flat walk, past the bottom of the Golden Stairs until the turn off to Ruined Castle. The turn off is signposted with the other track continuing on to Mt Solitary. The track up to Ruined Castle was a bit of a killer! It's got a serious climb that lasts for probably 1KM. Once past this it's mostly flat across the ridge to the castle.
From the bottom of the rocks which make up the Ruined Castle, is a short climb to the top of the rocks for the view.
Ruined Castle itself is well worth the walk, the 360 degree views over the Jamison valley are a real treat.
The walk back was uneventful aside from us all starting to get tired and that Landslide rock pile seeming harder on the way back! Once back at the scenic railway, we walked back up the Furber steps to the car park as we'd missed the last train out. It was starting to get dark around this time (about 6PM) but there was enough light to see us out of the valley, although we did have torches just in case we got caught. We got out of the valley, three very tired and sore walkers!
All up, we covered somewhere between 20 and 24KMs in around 6 hours which I think isn't bad going for one day!
I highly recommend the walk, although you may want to cut the distance down a bit by skipping the Giant Staircase and getting the Scenic Railway down, unless you're after a real workout. However, unless you have at least one experienced leader in the group, I wouldn't recommend the walk as it is not a walk to be taken lightly.
The Blue Mountains website grades the walk as for experienced walkers only and says the following:
"Experienced walkers only - High level of fitness and navigational skill required, minimum 3 in group. Advise friends or police of route and destination times".
I don't really agree with the navigational part unless they class reading signs as that. Either way, treat the walk with respect and make sure you have plenty of water as there isn't any to be found that's safe to drink on the walk itself.
