A SMALL DIGITAL NOTEBOOK

Make room for
clear thinking.

Useful little tools, careful notes, and a quieter place to get things done.

01 / WRITING

A little word count

0 words0 characters0 min read

Reading time is an estimate at 200 words per minute. Spaces count as characters.

02 / WORKING TOGETHER

A moment in three places

Singapore
New York
UTC

Dates and daylight saving time are included.

03 / SMALL DETAILS

Give JSON some breathing room

Check syntax and make a small JSON document easier to read. This tool preserves large numbers by leaving them as written; formatting changes only whitespace outside strings.

Nothing is uploaded.

From the notebook

Small things worth remembering.

WORKING ACROSS TIME ZONES

Write the date, too.

“Tomorrow at nine” is easy to misunderstand across time zones. Include a full date and a named time zone when sharing a meeting time. UTC is useful for logs; a local time with the date is kinder to a person reading an invitation.

Daylight saving time changes the difference between some cities during the year. Convert the date of the meeting, rather than relying on a fixed offset remembered from last month.

TEXT & DATA

Readable is easier to check.

Indenting a JSON file makes its structure easier to inspect, but attractive formatting does not make its contents correct. Check field names, expected types, and the meaning of each value as well as the syntax.

Keep an original copy before changing important data. Large numeric identifiers deserve particular care: some applications round numbers they cannot represent exactly. Store an identifier as a string when the receiving format allows it.

A GENTLER WORKFLOW

Leave a useful next step.

Before closing a task, leave a short note: what is finished, what remains uncertain, and the next concrete action. A useful note describes enough context to let tomorrow's you begin without repeating today's investigation.

A small, specific instruction beats a long list of intentions. “Check the date column in the imported file” is easier to act on than “finish the analysis.”
