Testnet Outage Post-Mortem

From 19 July through 24 July, the Stacks testnet had experienced repeated outages every few hours. The symptom was the repeated recurrence of errors such as the following:

WARN [1595867918.213] [src/chainstate/stacks/db/blocks.rs:2861] [ThreadId(6)] Block 36a6b25fb7dd1775761b80b567425dd886f35272a5cc6a7661df0d99662f9d1c state root mismatch: expected 2fbb24799b4ea08ca50a8a2c75749735a6aa60415758a1394525f789a109067c, got 65fbf51eea07de1a75c5c45373c6aa3c7975e88269948114c0468acbf461cf66

Reading data before application startup in Angular 2

In this demonstration I will show you how to read data in Angular2 final release before application startup. You can use it to read configuration files like you do in other languages like Java, Python, Ruby, Php.

This is how the demonstration will load data:

a) It will read an env file named 'env.json'. This file indicates what is the current working environment. Options are: 'production' and 'development';

b) It will read a config JSON file based on what is found in env file. If env is "production", the file is 'config.production.json'. If env is "development", the file is 'config.development.json'.

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

• Close Android File Transfer
• Open Activity Monitor and kill “Android File Transfer Agent”
• Go to where you installed “Android File Transfer.app” (I have it under /Applications)
• Ctrl+click –> “Show package contents”
• Go to Contents/Resources
• Rename “Android File Transfer Agent” to e.g. “Android File Transfer Agent_DISABLED”
• Then go to “/Users/username/Library/Application Support/Google/Android File Transfer” and again rename the Agent app.

This is the follow up to a post I wrote recently called From Require.js to Webpack - Party 1 (the why) which was published in my personal blog.

In that post I talked about 3 main reasons for moving from require.js to webpack:

1. Common JS support
2. NPM support
3. a healthy loader/plugin ecosystem.

Here I'll instead talk about some of the technical challenges that we faced during the migration. Despite the clear benefits in developer experience (DX) the setup was fairly difficult and I'd like to cover some of the challanges we faced to make the transition a bit easier.

AngularJS Directive Attribute Binding Explanation

When using directives, you often need to pass parameters to the directive. This can be done in several ways. The first 3 can be used whether scope is true or false. This is still a WIP, so validate for yourself.

1. Raw Attribute Strings

   <div my-directive="some string" another-param="another string"></div>
