Bypass CSP restrictions in create-react-app Chrome extensions

While building a React Chrome extension using the create-react-app utility (v2.x), I came across the following error on loading my unpacked extension:

Refused to execute inline script because it violates the following Content Security Policy directive: “script-src ‘self’
blob: filesystem: chrome-extension-resource:”. Either the ‘unsafe-inline’ keyword, a hash (‘sha256-
GgRxrVOKNdB4LrRsVPDSbzvfdV4UqglmviH9GoBJ5jk=’), or a nonce (‘nonce-…’) is required to enable inline execution.

Basically, this error arises as Chrome (or almost any modern browser) will not allow inline scripts to get executed. This CSP restriction resulted in the above error as the build script in create-react-app bundles the .js files in <script> tags in the <body> of index.html.

Clear Nginx Cache

Clearing Nginx's HTTP Cache

I recently implemented Nginx HTTP content caching on our WordPress web servers to improve page load speeds and eliminate redundant, unneeded server-side page rendering. Caching the pages was relatively straightforward, but clearing the cache required a custom workaround.

Nginx comes in two versions: free and “Nginx Plus” at $2,500/year. The free version of Nginx does not offer the needed cache-clearing features of Nginx Plus, and I wasn’t comfortable paying $20,000 for 8 instances without trying to build my own solution.

Our Nginx servers run as an HTTP proxy for multiple PHP/MySQL-backed WordPress sites. The goal was to cache the dynamic PHP HTML responses in Nginx and serve the HTML pages from Nginx to avoid redundant, CPU-intensive PHP renders.

Site Cache Configuration

The example below shows how PHP response caching is configured for a site (other nginx configuration details are excluded for brevity). A cache named cachedemo-prod is defined to store cached HTML f

I had a heck of a time getting a Cuckoo sandbox running, and below I hope to help you get one up and running relatively quickly by detailing out the steps and gotchas I stumbled across along the way. I mention this in the references at the end of this gist, but what you see here is heavily influenced by this article from Nviso

Theming Ant Design with Sass and Webpack

This is a solution on how to theme/customize Ant Design (which is written in Less) with Sass and webpack. Ant itself offers two solutions and a related article on theming, but these are only applicable if you use Less, the antd-init boilerplate or dva-cli.

What this solution offers:

use a single sass-file to customize (no duplicate variables for your project and Ant)
hot reload compatibility
no dependencies on outdated npm modules
easy integration with your existing webpack setup (webpack 3+ tested)

Refactoring for maintainability

There is no "right" way to do anything. Any best practice exists because it's been found by someone to be better than what they were doing before. Often there's a reason that one way is better... but no way is the perfect way. Everything has pitfalls.

If you've been working on a codebase — any code base — for more than a year, you have likely run into a few pitfalls. The decisions we make today have downstream consequences. It's difficult for young developers to tease out which choices will cause big problems in the future. It's difficult for seasoned developers to distinguish between how they usually do it and "the best way".

Best practices change all the time. Like any other type of technology, people are constantly finding ways to improve code. It can be a full time job keeping up with new developments... and emerging best practice don't always stick around. Anyone invested in the early days of ES6 may remember the hype around decorators. At the time they we

ERC20 token standard vulnerability classification.

Previously described at: ERC20 critical problems medium article.

Description.

ERC20 is the most common Ethereum token standard. It should be noted that it is also the first Ethereum's token standard as well.

It is also important that the original ERC20 proposal is a definition of token interface. EIP20 does not define a reference implementation for this token standard. Here is OpenZeppelin implementation of ERC20 token: https://github.com/OpenZeppelin/zeppelin-solidity/tree/master/contracts/token/ERC20

ERC20 token standard implementation assumes two ways of token transferring: (1) transfer function and (2) approve + transferFrom pattern.
