リモートワークスタイルチェック

昨今の社会情勢の影響もありリモートワークを導入する企業・チームが増えてきましたが、一口に「リモートワーク」といってもさまざまなスタイルがあります。

企業側と働く側のミスマッチを防ぐため、リモートワークにおける観点を列挙してみました。

リモートワーク比重度

どの程度リモートワークに比重を置いて導入しているかのチェックリストです。

So you want to modify the text of a PDF by hand...

If you, like me, resent every dollar spent on commercial PDF tools, you might want to know how to change the text content of a PDF without having to pay for Adobe Acrobat or another PDF tool. I didn't see an obvious open-source tool that lets you dig into PDF internals, but I did discover a few useful facts about how PDFs are structured that I think may prove useful to others (or myself) in the future. They are recorded here. They are surely not universally applicable --
the PDF standard is truly Byzantine -- but they worked for my case.

Preamble

There is a longstanding issue/missing feature/bug with sockets on Docker on macOS; it may never work; you'll need to use a network connection between Docker containers and X11 on macOS for the foreseeable future.

I started from this gist and made some adjustments:

the volume mappings aren't relevant/used, due to the socket issue above.
this method only allows X11 connections from your Mac, not the entire local network, which would include everyone on the café/airport WiFi.
updated to include using the host.docker.internal name for the the container host, instead.
you have to restart XQuartz after the config change.

Be Careful with Table Driven Tests and `t.Parallel()`

We Gophers, love table-driven-tests, it makes our unittesting structured, and makes it easy to add different test cases with ease.

Let’s create our table driven test, for convenience, I chose to use t.Log as the test function. Notice that we don't have any assertion in this test, it is not needed to for the demonstration.

func TestTLog(t *testing.T) {
	t.Parallel()

When you create a npm package, remember it might be used in a browser or a server, or even a command line utility… For each package you create, please pay attention at what it will be used for:

Is it going to be used as a dependency to a nodejs application that is not bundled? (e.g. command line utilities)
Is it going to be used as a dependency to a nodejs application that is bundled? (e.g. AWS Lambdas)
Is it going to be used as a dependency to a browser application (always bundled)?.

In cases 2) and 3) you want to allow for tree shaking.
In cases 1) and 2) you want to benefit from the "ES6"/"ES next" features supported natively by nodejs.
In case 3) you also want to benefit from the native support of "ES6" from your browser.
