If you’re using ox-hugo and want to have it generate markdown files with the date prefixing the markdown title you can use this snippet to do it on save with org-hugo-auto-export-mode turned on. 
 1 ( defun ox-date-slug-prop () 
 2 ( interactive ) 
 3 ( let (( dt ( format-time-string '%Y-%m-%d' ( apply #'encode-time ( org-parse-time-string ( org-entry-get ( point ) 'EXPORT_DATE'…
Having a useable logging and metrics stack for your hobby projects can be extremely expensive if you
stick them inside your kubernetes cluster or try and host them on a normal VPS provider (whether that means DigitalOcean or AWS). 
 Below is an example configuration I use for some hobby projects that uses a dedicated hosting provider (OVH). 
 This solves two main problems for me:…
If you need to connect to multiple databases in your buffalo app open up your
 models/models.go file: 
 Up at the top add a new var like: 
 1 var YourDB * pop . Connection 
 then in the init() func you can connect to it - the important part is to make
sure you call .Open : 
 1 	 YourDB , err = pop . NewConnection ( & pop . ConnectionDetails { 
 2 		 Dialect…
We’ll go over everything needed to get a small development environment up and running using code-server, buffalo and postgres for a remote dev environment. 
 First lets install Go and Buffalo with gofish : 
 1 apt-update
 2 curl -fsSL https://raw.githubusercontent.com/fishworks/gofish/master/scripts/install.sh | bash
 3 gofish init
 4 gofish install go 
 5 gofish…
When you setup your cloud9 IDE for the first time, it comes pre-installed with
go1.9 - if you’d like to update to the latest (as of this writing), just run the
following commands: 
 1 wget https://golang.org/dl/go1.14.6.linux-amd64.tar.gz
 2 sudo tar -C /usr/local -xzf ./go1.14.6.linux-amd64.tar.gz
 3 mv /usr/bin/go /usr/bin/go-old # move the old binary

In one form or another I’ve worked remotely since 2005 (with a brief mix of
remote/onsite for about 2 years). 
 Below is a checklist of the things I’ve found that are required to have a
succesful remote work life and ensure you join a great remote team. 
 Why I like working remote 
 If it’s going to be your first time working remote, you should figure out…
Here’s a sample application to show how to stitch together Buffalo, gqlgen
and graphql subscriptions. Github Repo 
 
 I’ll go over the important parts here. After generating your buffalo application
you’ll need a graphql schema file and a gqlgen config file: 
 1 # schema.graphql 
 2 type Example { 
 3 	 message : String

If you’ve been using helm you’ve inevitably run into a case where a 
 1 helm upgrade --install
 has failed and helm is stuck in a FAILED state when you list your deployments. 
 Try and make sure any old pods are cleared up (ie: if they’re OutOfEphemeralStorage or something other error condition). 
 Next to get around this without doing a helm delete NAME --purge :…
This is useful if you’re building a generic library/package and want to let people pass in types and convert to them/return them. 
 1 package main 
 2 
 3 import ( 
 4 	 'encoding/json' 
 5 	 'fmt' 
 6 	 'reflect' 
 7 )

 9 type Monkey struct { 
 10 	 Bananas int 
 11 }

If you have your imagePullPolicy: Always and deploys aren’t going out (for example if you’re using a static tag, like stable ) - then you may be running into a helm templating bug/feature. 
 If your helm template diff doesn’t change when being applied the update won’t go out, even if you’ve pushed a new image to your docker registry. 
 A quick way to fix this…
If your developing against kubernetes services or want to run your changes without pushing to a remote registry and want to run inside kubernetes: 
 First create a registry running in minikube: 
 1 kubectl create -f https://gist.githubusercontent.com/joshrendek/e2ec8bac06706ec139c78249472fe34b/raw/6efc11eb8c2dce167ba0a5e557833cc4ff38fa7c/kube-registry.yaml
 Forward your localhost:5000…

The goal of this project was to start with a base directory (in this case The Hidden Wiki) and start spidering out to discover all reachable Tor servers. Some restrictions were placed on this after a few trial runs: 
 
 Only HTML/JSON was parsed/spidered for more links to follow (no jpegs/xml, etc) 
 There were a few skipped websites, noteably: Facebook, Reddit, and a few Blockchain…
