Having a good set and forget, but really set and double-check every now and then, strategy for your backups is important. Backups need to be automated to get done but also need to be tested to make sure that you can recover files when needed. This article will look at a home or small company setup doing large scale backups on a budget.Read More
Currently running my Unifi Controller as a docker container which works great. If you ever ended up with a broken Unifi Controller or Cloud Key you know the hassle it is to re-adopt and re-provision all your network gear to get back to square one. You should really keep track of the automatic backups from Unifi.
I’m using ryansch/unifi-rpi container which has more then 10 million pulls on docker hub. There isn’t any information about handeling backups in the description which surprises me! It is however a pretty easy thing to setup properly. Since I’m running my Unifi Controller in docker on a Raspberry Pi Docker Swarm my biggest fear is to fry the SD card. If I fry the SD card on the docker node it will also fry the automatic backups the unifi controller writes to disk.Read More
For several applications around the house, I need a MySQL backend. The biggest database I run is about 60Mb of data for my Kodi media players. By using centralized storage like this I only need to update one of them when I add new media. Also convenient if I watch a movie in the living room, pause it, and then want to continue in the bedroom. A few years ago we actually did this with our apartment in San Francisco and our other apartment in Sweden. So this has been battle-proven over the years for me.Read More
For small home server applications like Hassio, Plex and headless BitTorrent boxes Raspberry Pi has been a great solution for years. I came to a point where I was running several ones with different software on it depending on it’s intended use. This, however, isn’t ideal for a number of reasons. Even though Raspberry Pis are cheap you usually end up underutilizing the hardware. So we could be running more stuff on the same hardware. The second issue is the setup, I have done numerous posts about setting up different systems and how to maintain them.Read More
CAPTCHA was first invented in 1997 to distinguish a human from a bot performing an action. Back in the day captchas were usually obscured or deformed letters. Before that, we had the simple question verification like “what is 1 + 9” which is simple enough once the bot scrapes it off the page.
In 2007 reCAPTCHA was originally launched and then acquired by Google in 2009. The new thing with reCAPTCHA is that the work effort used to prove you’re a human isn’t wasted. Initially, reCAPTCHA was used in the digitalization of the New York Times and Google Books archive. By presenting the user with images where the OCR had failed you got a human interpretation to add to the OCR results. By combining known and unknown images you could still be confirmed as a human while providing this service.Read More
Whenever you write PowerShell scripts that are going to be used for automation you need to secure your credentials. The best practice is to use a service account to execute the PowerShell script and delegate whatever privileges it needs to execute. When dealing with internal systems and resources that are usually pretty easy if they all authenticate from the same ecosystem or are integrated properly. But there is instances where you need to store credentials like when working with external APIs or deattached internal system.Read More
Cloud Functions is Google Cloud’s event-driven serverless compute platform. Run your code locally or in the cloud without having to provision servers. Go from code to deploy with continuous delivery and monitoring tools. Cloud Functions scales up or down, so you pay only for compute resources you use. Easily create end-to-end complex development scenarios by connecting with existing Google Cloud or third-party services.
It’s easy enough to get up and running with a local dev environment but with the basic setup you need to restart the dev server on every file change. Doing a lot of Google AppEngine development recently I got use to the dev server reloading changed files. When you have the basic environment up and running (specified here: https://cloud.google.com/functions/docs/functions-framework) just follow these simple steps.Read More
Been trying to use multiple Google reCAPTCHAs on the same page with mixed success. Reason for doing this is for example a login page with a reCAPTHCA for the login form and a modal opening with a reset password form. I prefer to use the “invisible” reCAPTCHA since it gives a cleaner look. To be able to use the native validation of forms in HTML5 i need to manually execute the reCAPTCHA when the form is submitted which gave me issues with multiple reCAPTCHAs.
Every now and then IIS application pools lock up and needs to be killed. You can add the field PID in Task Manager and then use cmd tools to find which one of the IIS Worker Process is the right one and kill it. I created a simple script that lists all the IIS Application Pools by name, select the one you need to kill and the script kills it. The script is available on my Github and is named IISAppPoolKiller.ps1. Please comment below what you have been using this for!
