fix(dev): update environment for website development

[hhromic]

The nodejs and npm packages installed from the stock Ubuntu Focal repository are outdated for the current website dependencies. This commit installs an updated Node.js (current LTS version) directly from the NodeSource repository instead.

The yarn package in the stock Ubuntu Focal repository is not the Yarn package manager. The package is actually an alias package for the unrelated cmdtest package (ref: https://packages.ubuntu.com/focal/yarn). This commit installs (enables) the correct yarn command using the same updated Node.js installation above.

Website development requires two tools not currently installed in the environment:

• Hugo (static site generator).
• htmltest (HTML checker for the website content).

This commit also installs these tools directly from their GitHub release assets. In the case of Hugo, the installed version matches the version currently specified in 'netlify.toml'.

In addition to all the above, this commit also improves the Ubuntu bootstrap script:

• Switches apt for apt-get as recommended for non-interactive scripts.
• Add missing temporary directory cleaning commands.

After all the above changes, the following now works properly in website/ in the environment:

make serve
make local-preview-build

You are on a roll 😄

You are on a roll 😄

Hehe I was trying to make the vector-dev environment work for the website given that I will be written some docs soon!
And I found all these "rough edges" while trying to use it. After this PR is merged all should be ready to go 💪.

Regression Detector Results

Run ID: 229b22dd-d55a-4b9a-88d0-bbdf7aa226fa
Baseline: 3dab239
Comparison: 4327776
Total vector CPUs: 7

Explanation

A regression test is an integrated performance test for vector in a repeatable rig, with varying configuration for vector. What follows is a statistical summary of a brief vector run for each configuration across SHAs given above. The goal of these tests are to determine quickly if vector performance is changed and to what degree by a pull request.

Because a target's optimization goal performance in each experiment will vary somewhat each time it is run, we can only estimate mean differences in optimization goal relative to the baseline target. We express these differences as a percentage change relative to the baseline target, denoted "Δ mean %". These estimates are made to a precision that balances accuracy and cost control. We represent this precision as a 90.00% confidence interval denoted "Δ mean % CI": there is a 90.00% chance that the true value of "Δ mean %" is in that interval.

We decide whether a change in performance is a "regression" -- a change worth investigating further -- if both of the following two criteria are true:

1. The estimated |Δ mean %| ≥ 5.00%. This criterion intends to answer the question "Does the estimated change in mean optimization goal performance have a meaningful impact on your customers?". We assume that when |Δ mean %| < 5.00%, the impact on your customers is not meaningful. We also assume that a performance change in optimization goal is worth investigating whether it is an increase or decrease, so long as the magnitude of the change is sufficiently large.

2. Zero is not in the 90.00% confidence interval "Δ mean % CI" about "Δ mean %". This statement is equivalent to saying that there is at least a 90.00% chance that the mean difference in optimization goal is not zero. This criterion intends to answer the question, "Is there a statistically significant difference in mean optimization goal performance?". It also means there is no more than a 10.00% chance this criterion reports a statistically significant difference when the true difference in mean optimization goal is zero -- a "false positive". We assume you are willing to accept a 10.00% chance of inaccurately detecting a change in performance when no true difference exists.

The table below, if present, lists those experiments that have experienced a statistically significant change in mean optimization goal performance between baseline and comparison SHAs with 90.00% confidence OR have been detected as newly erratic. Negative values of "Δ mean %" mean that baseline is faster, whereas positive values of "Δ mean %" mean that comparison is faster. Results that do not exhibit more than a ±5.00% change in their mean optimization goal are discarded. An experiment is erratic if its coefficient of variation is greater than 0.1. The abbreviated table will be omitted if no interesting change is observed.

No interesting changes in experiment optimization goals with confidence ≥ 90.00% and |Δ mean %| ≥ 5.00%.

Fine details of change detection per experiment.

Happy to report that the newly published vector-dev image in DockerHub works fine to build the website now 🎉 🍻
