The greatest strength of an airgapped machine is also it's biggest headache - no way out! This is a short guide for configuring an old Raspberry Pi 2 (no radio cards!) to securely use the eth2-deposit-cli tool. Whether using an existing mnemonic or generating a new one, the security conscious will appreciate doing so on a machine which never has and never will touch any network.

Note: This is an older post that I did back when I thought I might have time to be a blogger. Oh I was oh so wrong. However, it has proven useful for some folks on stackoverflow. Thus I'm keeping it alive here on Gist.
One of my past projects dealt heavily with an open source Apple technology called HTTP Live Streaming. It’s an HTTP based streaming protocol that at its most fundamental level provides a way to stream video and audio from just about any server with nothing but a few free software tools provided by Apple**. However, it has a few additional features that I think make it a really exciting tool. Yet, I haven’t seen HTTP Live Streaming used very much. This is probably mainly due to the combination of a lack of good/clear documentation, and Apple’s Live Streaming Developer Tools being command line based also make the barrier to entry higher than many developers want to deal with.
The hope is to share my understanding of how to use this technology to:
| NSManagedObjectContext *context = object.managedObjectContext; | |
| while (context != nil) { | |
| NSError *error = nil; | |
| BOOL result = [context save:&error]; | |
| NSAssert(result != NO, @"[ERROR]: Context was not saved"); | |
| if (result) { | |
| context = context.parentContext; | |
| } else { |
| @objc public enum AppContextError: Int, CustomStringConvertible, CustomNSError, LocalizedError { | |
| case badParameters | |
| case unknownError | |
| case connectNotSupported | |
| public static var errorDomain: String { | |
| return "AppContextError" | |
| } |
Say you're running a virtual machine on your work computer. Say this machine, for whatever reason, can only connect to the internet over NAT - as in, it does not get it's own IP address. Say this VM is running a webserver, and you need a device outside of your computer to connect to it.
If only there was a way to get your work computer to 'share' it's network, so that you could get at that VM… Here's how you do it!
For all instructions, I assume your work computer is a mac
