Benchmarking is Hard, Yo.

So, I was reading Why You shouldn’t use lodash anymore and use pure JavaScript instead, because once upon a time, I shifted from Underscore to Lodash, and I'm always on the lookout for the bestest JavaScript stdlib. At the same time, there was recently an interesting conversation on Twitter about how some of React's functionality can be easily implemented in modern vanilla JS. The code that came out of that was elegant and impressive, and so I have taken that as a message to ask if we really need the framework.

Unfortunately, it didn't start out well. After copy-pasting the ~100 lines of code that Lodash executes to perform a find, there was then this shocking claim: Lodash takes 140ms, and native find takes 0ms.

lodash/fp set and flow

lodash/fp - set / flow

In this gist we are going to learn about basic goodies that we get from the library lodash/fp (fp stands for functional programming, great for ensuring immutability).We'll learn just by doing (step by step guided sample + codepens).

We'll cover lodash set and flow functions

Steps

  • We'll use codepen as our playground, navigate to this page:

Secure random values (in Node.js)

Not all random values are created equal - for security-related code, you need a specific kind of random value.

A summary of this article, if you don't want to read the entire thing:

  • Don't use Math.random(). There are extremely few cases where Math.random() is the right answer. Don't use it, unless you've read this entire article, and determined that it's necessary for your case.
  • Don't use crypto.getRandomBytes directly. While it's a CSPRNG, it's easy to bias the result when 'transforming' it, such that the output becomes more predictable.
  • If you want to generate random tokens or API keys: Use uuid, specifically the uuid.v4() method. Avoid node-uuid - it's not the same package, and doesn't produce reliably secure random values.
  • If you want to generate random numbers in a range: Use random-number-csprng.

You should seriously consider reading the entire article, though - it's

Top-level `await` is a footgun

Edit — February 2019

This gist had a far larger impact than I imagined it would, and apparently people are still finding it, so a quick update:

  • TC39 is currently moving forward with a slightly different version of TLA, referred to as 'variant B', in which a module with TLA doesn't block sibling execution. This vastly reduces the danger of parallelizable work happening in serial and thereby delaying startup, which was the concern that motivated me to write this gist
  • In the wild, we're seeing (async main(){...}()) as a substitute for TLA. This completely eliminates the blocking problem (yay!) but it's less powerful, and harder to statically analyse (boo). In other words the lack of TLA is causing real problems
  • Therefore, a version of TLA that solves the original issue is a valuable addition to the language, and I'm in full support of the current proposal, which you can read here.

I'll leave the rest of this document unedited, for archaeological

Importing and Exporting CSV files with PostgreSQL — First published in fullweb.io issue #19

Importing and exporting CSV files with PostgreSQL

Let’s see how to use PostgreSQL to import and export CSV files painlessly with the COPY command.

Import CSV into table t_words:

COPY t_words FROM '/path/to/file.csv' DELIMITER ',' CSV;

You can tell quote char with QUOTE and change delimiter with DELIMITER.
