Years ago I started writing a #specification for a family of binary file formats with three goals:
- Extremely simple for mmapped access
- Frozen in time (no versioning)
- No complex algorithms to read/write the data
I still think there's value to those formats, since the tasks they try to ratify come up time and again, and there seems to be no simple equivalent
I never finished it because I feel I still need more feedback. If you're interested, please have a read:

Regular expression pattern modifiers · A look at a feature expected in ECMAScript 2025 https://ilo.im/161s45

ilo.imECMAScript feature: regular expression pattern modifiersTraditionally, we could only apply regular expression flags such as i (for ignoring case) to all of a regular expression. The ECMAScript feature “Regular Expression Pattern Modifiers” (by Ron Buckton) enables us to apply them to only part of a regular expression. In this blog post we examine how they work and what their use cases are. Regular expression pattern modifiers attributes reached stage 4 in October 2024 and will probably be part of ECMAScript 2025.

@mrchrisadams Yeah, #S3-Style #ObjectStorage is nifty in many places.
- It's kinda good that whilst #amazon is a bad company, they basically had to "#OpenSource" S3 as a #specification so anyone would even bother to implement it at all, and basically every #hoster nowadays offers that with bit & second-precise billing if wanted, as it's more convenient to #FTP and other #quota / #fixed storage...

In this blog post, we examine what that looks like and why it’s useful. Import attributes reached stage 4 in October 2024 and will probably be part of ECMAScript 2025.
recently I stumbled upon https://github.com/w3c/activitystreams/issues/616#issuecomment-2498990563 and (apart from this concrete issue) it make me think about how _new_ users to the protocol understand the use of multiple languages
The problem why the #ActivityPub #Specification has a deep learning curve:
In order to understand the use of multiple languages, you need to read at least 4 specifications.
Any user of the software can say: I speak language X in quality Y.
It might not be obvious to new users that it is the according
- HTTP "accept-language" header
like e.g. "de,en-US;q=0.7,en;q=0.3"
The default language is defined in the
- JSON-LD spec. as described in above issue
The primer to read about how to use it is in the
- AS Core specs.
https://www.w3.org/TR/activitystreams-core/#naturalLanguageValues
while the properties are described in the
- Vocabulary specs.
e.g. https://www.w3.org/TR/activitystreams-vocabulary/#dfn-name
While this is understandable and fine for me, it might be confusing to new or non-tech-implementors …

I just found out that the @ietf recently published JSContact yet another specification for storing contact data.
It’s super interesting, though, and I am falling down the rabbit hole of all the links and related information about this. 
One of the authors is Mario Loffredo, “First Technologist” of the Informatics and Telematics section of the Italian National Counsel for Research (CNR). 
It’s the first time I find an Italian in public sector research authoring a spec!
I just sent him a Linkedin connection request, even if I don’t even know why…
IETF DatatrackerRFC 9553: JSContact: A JSON Representation of Contact DataThis specification defines a data model and JavaScript Object Notation (JSON) representation of contact card information that can be used for data storage and exchange in address book or directory applications. It aims to be an alternative to the vCard data format and to be unambiguous, extendable, and simple to process. In contrast to the JSON-based jCard format, it is not a direct mapping from the vCard data model and expands semantics where appropriate. Two additional specifications define new vCard elements and how to convert between JSContact and vCard.
