What Do The Logs Show

What Do The Logs Show

Joke: I was on the phone with tech support when I walked by these and I was asked “What do the logs show?” I had a double take before I understood he meant the web logs and other server logs. I then continued walking

I am getting somewhere with my studies. I feel that I am now starting to understand ideas and contexts and that as a result I can start working towards reaching and getting stuck on the next plateau, and the next one after that. In short, I am making progress.


Today the Steripen adventure opti arrived and I tested it in a container. Testing such a device on clean water is useless. I did learn that it is not dead on arrival.


I heard about ClassicPress while listening to a podcast so I downloaded the files, copied them to the htdocs folder, entered a few bits of information and it was up and running on my local machine. ClassicPress is a fork of WordPress.org. It aims to provide those who do not like Gutenburg with an alternative solution where they keep control of how posts are formated and displayed.


For now you can download wordpress plugins and use them on ClassicPress but I don’t know for how long this interoperability will last. There is an explanation about how to use shims to use incompatible apps.

JavaScript Patterns, A Skipped Walk And A New Purchase.

JavaScript Patterns, A Skipped Walk And A New Purchase.

Byrichard

Today I found a course about JavaScript patterns on Linkedin. I have been following course after course about Ruby, Ruby on Rails, JavaScript, Angular, React, EcmaScript, CSS and more, but most of them tell you how to do things. I watched plenty of their explanations and I managed to copy the code and get it to work but when they said “challenge time” I was usually lost.


I listened to the JavaScript Jabber podcast and in several episodes they described design patterns. In all of my learning I have learned how to read and copy code. By learning about programme patterns I will learn to structure code correctly. With these notes I will have a blueprint from which to work.


The Skipped Walk


The drawback to recycling being open at certain times of days, on certain days, is that you don’t get an opportunity to go when you want to go. You have to go when the system wants. For this reason I have not been on my daily walk today. I feel tired and lazy anyway. I skip my daily walk once every few months, so missing one day is not the end of the world.


SteriPEN Adventurer Opti


Years ago I walked up a mountain. We reached over 3000m. For that hike, as it was expeted to be a long hike I took three litres oI found walking with three litres of water so tiring because I am not used to being at that altitude. By the end of the walk I decided to find a way to filter water while hiking.


For weeks and months I studied options and I finally settled on one option, then a second, and then a third, etc. I then enjoyed using the Katadyn BeFree the most. On day hikes anything more is overkill.


The drawback: in Switzerland most water sources are below animals and humans. This means that water sources can contain viruses. For this reason it is a risk to drink the water. The solution is to get rid of those viruses. Water filtration systems do not do this. They remove bacteria, protozoa etc. You could boil the water but that takes time and that adds weight. You can use water filtration tablettes but that takes time to act, and adds taste to the water.


The lightweight solution is a device like the SteriPen Adventure Opti. They are light to carry, can filter about 50 litres of water in between battery changes, and last for 8000 litres, in theory. In practice you might lose, break or otherwise find its life shortened.


I found the steripen for 30CHF and they usually cost 90-110CHF. 100 tablettes cost 23 CHF to filter water.

Clean Water for Hikes and cycling, without the weight

Byrichard

Clean water is important to have when you’re cycling, hiking or climbing in summer but the issue is that it is heavy. When I go cycling I go with just one flask and I fill up the water bottle when I get to fountains that are marked as safe to drink from. When I go hiking or climbing I usually do not go with more than one and a half litres of water although I have gone with up to three litres for a hot summer day’s activities when the temperature is above 32°c.

In Switzerland, France and Italy you theoretically do not need to walk with that much water because you cross streams, fountains, rivers and lakes. If you had a water filtration system you could theoretically purify the water from these sources and continue hiking. Yesterday I came across Katadyn and two solutions for water filtration.

Katadyn BeFree

The Katadyn BeFree is a collapsible water bottle system that you fill from unfiltered water and then filter as you drink. This system also allows you to refill clean water containers within a very short lapse of time. It takes very little space in your bag and it’s light. It’s easy to have this with you at all time. It would be practical for cycling and climbing. You leave home with clean tap water and when you run out of clean water you fill this system and squeeze clean water in to your clean water bottle and continue the day’s activities. I have seen this system for 45 CHF in Switzerland.

Katadyn Hiker Pro

The Katadyn Hiker Pro is a slightly more expensive but portable solution. It allows you to filter water straight from a river, stream or lake to a clean water recipient.  It has a first filter on the hose that goes from the water source to the pump. The pump has a pre-filter to get rid of any sediment still suspended in water and the third filter filters out almost all bacteria. Clean water then flows from the pump to the clean water container. If you’re climbing near a river or exploring a via ferrata near a waterfall then the need to carry water is reduced.

SteriPen Water purifiers

According to this article you can go a step further to stay safe. Almost every article and review mentions that the two systems above are not designed to kill viruses. If you want to go that extra step then you have the Steripen Aqua UV Water purifier.  It is meant to kill almost all bacteria and viruses. The link is to the cheapest model. The second option is to boil water.

“Boiling can be used as a pathogen reduction method that should kill all pathogens. Water should be brought to a rolling boil for 1 minute. At altitudes greater than 6,562 feet (greater than 2000 meters), you should boil water for 3 minutes.Apr 10, 2009” source:

Water Quality maps

If you’re going to drink river or lake water in Switzerland this document from March, 2017 provides maps with water quality information. In some areas waters may be contaminated with chemicals or pesticides and it is good to check that cattle are not upstream of your water source.
