Reliable SwiftUI mouse hover

Reliable mouseEnter/Exit for SwiftUI

Kapture 2021-03-01 at 14 43 39

On Mac, SwiftUI's .onHover closure is not always called on mouse exit, particularly with high cursor velocity. A grid of targets or with finer target shapes will often have multiple targets falsely active after the mouse has moved on.

It is easy to run back to AppKit's safety. Below is a SwiftUI-like modifier for reliable mouse-tracking. You can easily adapt it for other mouse tracking needs.

How to deal with JWT expiration?

First of all, please note that token expiration and revoking are two different things.

  1. Expiration only happens for web apps, not for native mobile apps, because native apps never expire.
  2. Revoking only happens when (1) uses click the logout button on the website or native Apps;(2) users reset their passwords; (3) users revoke their tokens explicitly in the administration panel.

1. How to hadle JWT expiration

A JWT token that never expires is dangerous if the token is stolen then someone can always access the user's data.

Quoted from JWT RFC:

Virtual hosts

Let's say you want to host domains first.com and second.com.

Create folders for their files:

<?xml version="1.0" encoding="UTF-8"?>

How to proxy web apps using nginx?

Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers

Automounting NFS share in OS X into /Volumes

I have spent quite a bit of time figuring out automounts of NFS shares in OS X...

Somewhere along the line, Apple decided allowing mounts directly into /Volumes should not be possible:

/etc/auto_master (see last line):

#
# Automounter master map
#

+auto_master # Use directory service
