Watched @pid_eins #fosdem2026 presentation record about #Varlink. I think the idea is good, except it should use some binary protocol for communication between services. RFC 8949 #CBOR seems like excellent candidate. Text serialization is not necessary if human is never direct part of a pipeline. Data conversion is not slow, but not necessary between localhost- only services.

The sign is a lie (and they knew that advance: train goes only to Köln), but still on my way to #FOSDEM.

Happy any time to talk about #CoAP, #CBOR, #DectNrPlus, IoT security and embedded Rust development, especially on @ariel and @RIOT_OS.

Hello #Proteomics !

Thinking about a better mzML to store proteomics data, but not convinced by the #parquet approach, I've converted it into #CBOR :
* Smaller data files (only 66% of the mzML original file) for the exact same data
* Faster to read (25s for a big mzML vs 18s in mzcbor on the same computer)
* Very quick random access to spectra (24.6577 ms for mzML vs 786.731 μs for mzcbor for the same operation using index)

I'd like to share it if you are interested at #eubIC #eubic2026

Проектируем как синьор: универсальная бинаризация

Здравствуйте, меня зовут Дмитрий Карловский и я.. да не важно кто я. Важно о чём я говорю, и как аргументирую. Кто меня знает, тому и не надо рассказывать. А кто не знает — у того есть прекрасная возможность подойти к вопросу с чистым разумом. А это крайне важно, если мы хотим спроектировать что-то по настоящему хорошо, а не как обычно. Что ещё за VaryPack?

JSON? JSONB? BSON? CBOR? MsgPack? А, VaryPackǃ

VaryPack - новый, простой, гибкий, шустрый и компактный формат бинарной сериализации произвольных данных. Что за модная тема?

OH in the #CBOR meeting of #IETF:

Everything you can do on a light bulb, you can do [on a computer] a billion times.

@algernon Still undecided, I'm considering #CBOR diagnostic format, but it's not ideal either.

@lambdageek That's a good observation, and helps me express the troubles I face using it with idiomathc #CBOR

🌘 從 XML 到 JSON 再到 CBOR：資料的通用語言？
➤ 探究資料交換格式的演進歷程，理解從結構化文件到二進位效率的轉變
✤ https://cborbook.com/introduction/from_xml_to_json_to_cbor.html
本文深入探討了現代計算中至關重要的資料交換格式的演進，從具有強健文件結構的 XML，轉向以網路為中心的 JSON，再到專為受限裝置設計的二進位效率格式 CBOR。文章詳細闡述了 XML 的起源、設計原則、優勢與侷限，以及它如何演變成現代資料交換的基石。
+ 這篇文章對於 XML 的起源和發展有非常詳盡的介紹，讓我對它在網路時代的地位有了更深的認識。
+ 很好奇接下來的 JSON 和 CBOR 會如何介紹，期待了解它們的優勢和與 XML 的區別。

CBOR Tag for JSON Number Strings

https://justatheory.com/2025/05/cbor-json-number-string/

#golang #cbor #ietf #iana

I got an IANA assignment registered: “JSON Number String Tag for CBOR.” Useful to preserve string literal representation of JSON numbers, such as those created by Go's json.Number.

https://gist.github.com/theory/ef667af1c725240e6e30d525786d58e6

Will show up on https://www.iana.org/assignments/cbor-tags/cbor-tags.xhtml soonish.

#golang #cbor

Nice new milestone for #embedded #Rust development: defmt 1.0 has been released. The crate enables logging for microcontrollers without text or number formatting on the device – instead, the device sends numbers of interned strings to the host, which composes log messages.
1.0 is not only a stable release, but also enables logging #CBOR data into diagnostic notation on the host.

#RustLang

The #IETF122 hackathon starts in a few hours. I will be joining remotely, work on #EDHOC on @ariel (let's see if its out-of-the-box support also interoperates out-of-the-box), and play with #embeddfriendly URIs expressed in #CBOR.

RFC 9741: CDDL Additional Control Operators for the Conversion and Processing of Text

Le langage #CDDL, qui permet de créer un schéma formel pour des formats comme #CBOR, peut s'étendre via l'ajout d'« opérateurs de contrôle ». Ce #RFC en spécifie quelques uns, notamment pour agir sur du texte ou convertir d'une forme dans un autre.

https://www.bortzmeyer.org/9741.html

My recent work on #CBOR diagnostic tools has culminated in the release v0.0.7 of the cbor-edn #RustLang crate, and the cbor-diag v1.1.0 #Python package (which is powered by the former, #maturin and #PyO3).
It is now easy to receive CBOR data structure with internal tags, and have them display like this:
{1: IP'2001:db8::1', 3: DT'2025-01-14T13:27:49Z'}

RFC 9682: Updates to the CDDL grammar of RFC 8610

Voici une légère mise à jour de la grammaire du langage de description de schéma #CDDL (Concise Data Definition Language), originellement normalisé dans le RFC 8610. Pas de gros changement.

#CBOR #RFC

Starting into a busy #IETF121 day: talking about #CoAP in the morning CoRE meeting, IoT lunch, #CBOR in afternoon, and board game night to unwind.
And that's only the Tuesday :-)

"ChatGPT can explain it, so it means the spec is fine."

#CBOR #IETF121

#DNS encoded in #CBOR (for IoT). Two implementations (including one in RIOT.)

(Not related to C-DNS.]

#IETF121

This week, I am at the @ietf Hackathon and #IETF121 in Dublin. In #CoRE and #CBOR WGs, I will present #DNS over #CoAP and related work to make DNS more concise and resource-friendly. Check our drafts at https://datatracker.ietf.org/person/martine.lenders@tu-dresden.de
