airtable-export. I wrote a command-line utility for exporting data from Airtable and dumping it to disk as YAML, JSON or newline delimited JSON files. This means you can backup an Airtable database from a GitHub Action and get a commit history of changes made to your data. # 29th August 2020, 9:48 pm

Subsume JSON a.k.a. JSON ⊂ ECMAScript (via) TIL that JSON isn’t a subset of ECMAScript after all! “In ES2018, ECMAScript string literals couldn’t contain unescaped U+2028 LINE SEPARATOR and U+2029 PARAGRAPH SEPARATOR characters, because they are considered to be line terminators even in that context.” # 15th August 2019, 10:30 am

jq recipes. Remy Sharp’s handy collection of jq recipes, each one linking to an interactive demo on jqterm.com. I thought jq was just for extracting values from a JSON document—I hadn’t realized how powerful it was for modifying and extending those documents as well. # 22nd August 2018, 3:23 pm

“MongoDB is fantastic for logging”. Sounds tempting... high performance inserts, JSON structured records and capped collections if you only want to keep the past X entries. If you care about older historic data but still want to preserve space you could run periodic jobs to roll up log entries in to summarised records. It shouldn’t be too hard to write a command-line script that hooks in to Apache’s logging directive and writes records to MongoDB. # 26th August 2009, 7:09 pm

Tile Drawer (via) The most inspired use of EC2 I’ve seen yet: center a map on an area, pick a Cascadenik stylesheet URL (or write and link to your own) and Tile Drawer gives you an Amazon EC2 AMI and a short JSON snippet. Launch the AMI with the JSON as the “user data” parameter and you get your own OpenStreetMap tile rendering server, which self-configures on startup and starts rendering and serving tiles using your custom design. # 26th August 2009, 9:32 am

addSizes.js: Snazzy automatic link file-size generation. Posted to Nat’s snazzy new blog: a script that uses my json-head API to grab the file size of linked documents on a page and insert those sizes in to the document. # 30th August 2008, 10:39 am

json-tinyurl. Because sometimes you want to be able to create a shorter version of a URL directly from JavaScript without hosting your own server-side proxy. # 27th August 2008, 10:58 am

Dare left something out (and it’s important). Dave Winer: “You should at least learn the lessons and add to REST what it needs to catch up with XML-RPC. Seriously. What’s missing in REST, btw, is a standard method of serializing structs, lists and scalar types.” That would be JSON. # 18th August 2008, 9:39 am

IMG-2-JSON (via) I’m not the only person deploying simple JSON-P APIs on App Engine: Adam Burmister’s tool extracts dimension, mimetype and EXIF metadata when provided the URL to an image file. # 12th August 2008, 9:43 am

Cabochon event server. Written in Python (on top of SQLObject and Paste), uses JSON for messages, allows event consumers to subscribe with a callback URL. # 2nd August 2007, 8:36 am

Proposed RFC for application/json (via) Douglas Crockford is putting JSON through the IETF. # 1st August 2006, 9:29 pm
