Mac software essentials

Well, after the Firefox Essentials, here’s my list of Mac essentials: LaunchBar Homebrew Firefox Beta Exact Scan Pro (scanner utilities for Mac are still … all bad, this is absolutely good and relatively the best. VueScan might be better for about 0.05% of all scans I do, but the usability could actually not be any worse) The Unarchiver Sublime Text, or probably in the future Atom (text editors) Cubby and Bittorrent Sync (document sync, don’t really like Dropbox) VLC player Better Snap Tool (yah, don’t really get the split screen of OS X) PDF Expert or PDF Pen Pro (both good, the first is way cheaper, and the reason is that Preview can actually make PDF files bigger on edits like remove pages, or rearrange pages) Amphetamine (keep your Mac awake) Typinator (text epansion) Twitter client (I actually use the official one) Libre Office Telegram (useful Whatsapp alternative, cause it also has a web interface) Path Finder Shimo (VPN client, really expensive, but “use this password for all connections in this folder” is awesome) Hazel

My essential Firefox addons

… can be seen on the Firefox Addons page as collection 🙂 . The addon ecosystem of Firefox is what keeps me with it. And the way it’s done. One example: Mouse Gestures are available on Chrome, which seems to be a lot faster and smoother today :’( … but in FF, when I go to the settings page, I can still use mouse gestures, cause it’s just another page. In Chrome I can’t. I like the Firefox behavior - it’s consistent, which is highly a highly underrated property these days. ...

Rancher IAM role

Rancher can create instances on EC2. If you want to define a dedicated IAM user for this, refer to the Amazon docs for the a profile template. Unfortunately the first thing you get when using those permissions in rancher is “You are not authorized”. Great. I’ll update this when I know the correct permissions. (Source: Rancher docs)

VPC with NAT to internet on AWS

… and other TLAs. Anyways, as far as I remember OpenStack does not need this, so I thought I document it here. I at least was surprised. Situation: You want a private network sement in the cloud (in my case an Amazon VPC), and you don’t want all hosts to be accessible from the internet. So you don’t assign public IPs, and you need a router/gateway. Amazon creates a network internet gateway, but this thing does not do one thing: NATting. If your host does not have a private IP, it can’t connect to “the internet”. ...

CI / CD solutions

Everyone wants free candy. Or a CI/CD solution, that … auto-deploys container-based servcies auto-updates (roll-forward, roll-back) those services on keypress and “triggers” has one-click-deployment of services. My definition of “service” here is “A set of containers working together in a certain way, automatically load balanced where needed”. Example: A n worker nodes, loadbalanced from a web endpoint, and a database container. All deployed at the same time. Including one-click-deployment of environments (“Oh, I’d like to test this revision again, let’s deploy it quickly”…). Note that this is mostly CD (continuous deployment), cause CI is being done for a while now with - mostly - Jenins and other tools. ...
