Miller is like awk, sed, cut, join, and sort for name-indexed data such as CSV, TSV, and tabular JSON. You get to work with your data using named fields, without needing to count positional column indices.

This is something the Unix toolkit always could have done, and arguably always should have done. It operates on key-value-pair data while the familiar Unix tools operate on integer-indexed fields: if the natural data structure for the latter is the array, then Miller’s natural data structure is the insertion-ordered hash map. This encompasses a variety of data formats, including but not limited to the familiar CSV, TSV, and JSON. (Miller can handle positionally-indexed data as a special case.)

Being able to send emails from command-line from a server is quite useful when you need to generate emails programatically from shell scripts or web applications for example.

This tutorial explains, how to use to the mail command on linux to send mails from the command-line using the mail command.

Bristol is an emulation package for a number of different 'classic' synthesisers including additive and subtractive and a few organs. The application consists of the engine, which is called bristol, and its own GUI library called brighton that represents all the emulations.

There are currently twenty something different emulations, each does sound different although the author maintains that the quality and accuracy of each emulation is subjective. One of the main reasons for putting together this site (host by Sourceforge which provides the rest of the services required by bristol) is to depict all the different emulations.

I work on a lot of Javascript projects. The fashion in Javascript is to use build tools like Gulp or Webpack that are written and configured in Javascript. I want to talk about the merits of Make (specifically GNU Make).

Make is a general-purpose build tool that has been improved upon and refined continuously since its introduction over forty years ago. Make is great at expressing build steps concisely and is not specific to Javascript projects. It is very good at incremental builds, which can save a lot of time when you rebuild after changing one or two files in a large project.

Make has been around long enough to have solved problems that newer build tools are only now discovering for themselves.

Despite the title of this post, Make is still widely used. But I think that it is underrepresented in Javascript development. You are more likely to see a Makefile in a C or C++ project, for example.

My guess is that a large portion of the Javascript community did not come from a background of Unix programming, and never had a good opportunity to learn what Make is capable of.

I want to provide a quick primer here; I will go over the contents of the Makefile that I use with my own Javascript projects.

C3 makes it easy to generate D3-based charts by wrapping the code required to construct the entire chart. We don't need to write D3 code any more.

Customizable

C3 gives some classes to each element when generating, so you can define a custom style by the class and it's possible to extend the structure directly by D3.

Controllable

C3 provides a variety of APIs and callbacks to access the state of the chart. By using them, you can update the chart even after it's rendered.

C3 enables deeper integration of charts into your application.

Suppose you want to find out how many times particular text or a number value occurs in a range of cells. For example:

If a range, such as A2:D20, contains the number values 5, 6, 7, and 6, the number 6 occurs two times.

If a column contains "Buchanan", "Dodsworth", "Dodsworth", and "Dodsworth", "Dodsworth" occurs three times.

Use VLOOKUP, one of the lookup and reference functions, when you need to find things in a table or a range by row. For example, look up a price of an automotive part by the part number.

In its simplest form, the VLOOKUP function says:

=VLOOKUP(Value you want to look up, range where you want to lookup the value, the column number in the range containing the return value, Exact Match or Approximate Match – indicated as 0/FALSE or 1/TRUE).

There is something called 'locked reference' in excel which you can use for this, and you use $ symbols to lock a range. For your example, you would use:

=IF(B4<>"",B4/B$1,"")

This locks the 1 in B1 so that when you copy it to rows below, 1 will remain the same.

If you use $B$1, the range will not change when you copy it down a row or across a column.

This guide is intended to catch you up with the most important reasoning, terms, tools, and approaches to JavaScript testing in 2018.

app.get('/:var(bla|blabla)?', todo)

:var sets the req.param that you don't use. it's only used in this case to set the regex.

(bla|blabla) sets the regex to match, so it matches the strings bla and blablah.

? makes the entire regex optional, so it matches / as well.

This lightweight tool helps you get a sense of your application's schema, as well as any outliers to that schema. Particularly useful when you inherit a codebase with data dump and want to quickly learn how the data's structured. Also useful for finding rare keys.
