iPad Pro 12.9" (2020) Magic Keyboard Portrait Mode DIY Smart Connector Cable

I wanted my iPad Pro to be able to use the Magic Keyboard in portrait mode, but the current Smart Connector configuration does not allow this. With too much time on my hands, I made a short jumper cable using a section of USB cable, 5-pin POGO connectors (the 5-pin works using pins 1, 3, and 5, and removing pins 2 and 4), a small electrical project box, 3mm N52 magnets, and some epoxy and Sugru to pack everything into place. My cable and connections orientation had more to do with the boxes I found to encase the connector (with holes on the small end) than anything else. Obviously, there will be many ways to do this.

WARNING: Getting any of these steps wrong will probably ruin your iPad.

Note: These measurements are for the 12.9" (2020) model. The magnets did not line up and the polarity was different for my wife's iPad Pro 11" (2021).

Synology: how to increase shutdown temperature

My Synology DS218+ runs with a single SSD disk that has an operating temperature range of 0–70 °C, which is common for SSDs. Synology, however, has a default shutdown temperature of 61 °C, probably due to HDDs and some lazy programming.

I'm a very light user of NAS – all I want is a network attached storage and silence. My DS218+ has one 2 TB SSD disk in it and I've changed the system fan for a quieter / slower one.

Everything runs fine but about once in a month, I get this notification:

[Synology DS218+]Synology shut down due to disk overheating. >

Unofficial Bash Strict Mode

Sometimes a programming language has a "strict mode" to restrict unsafe constructs. E.g., Perl has use strict, Javascript has "use strict", and Visual Basic has Option Strict. But what about bash? Well, bash doesn't have a strict mode as such, but it does have an unofficial strict mode:

set -euo pipefail

set -e

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

Expiration only happens for web apps, not for native mobile apps, because native apps never expire.
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:

Building TensorFlow 1.3.0-rc1 for Raspberry Pi/Ubuntu 16.04: a Step-By-Step Guide

Here you'll learn how to build Tensorflow for the raspberry pi 3 with either the Python API or as a standalone shared library which can be interfaced from the C++ API and eventually as a library which can be used in other languages.

For the C++ library this tutorial will show you how extract tensorflow library and headers to use in any environment you want.

What You Need

GPG and git on macOS

Setup

No need for homebrew or anything like that. Works with https://www.git-tower.com and the command line.

Install https://gpgtools.org -- I'd suggest to do a customized install and deselect GPGMail.
Create or import a key -- see below for https://keybase.io
Run gpg --list-secret-keys and look for sec, use the key ID for the next step
Configure git to use GPG -- replace the key with the one from gpg --list-secret-keys

trace-deopt.sh

How to use

./trace-deopt.sh http://localhost:4200

Introduction to Kafka

Kafka acts as a kind of write-ahead log (WAL) that records messages to a persistent store (disk) and allows subscribers to read and apply these changes to their own stores in a system appropriate time-frame.

Terminology:

Producers send messages to brokers
Consumers read messages from brokers
Messages are sent to a topic
