Re:Parsing EDIFACT in Python with syntax trees on Saturday October 24, 2026 @05:08PM (#50225306)
Care to share what "right architecture" could look like? There's surprisingly little public engineering reading about EDI...

Did anyone benchmark against Buns‘ new time typecheck that landed in v 1.4.3? I would do it but too far away from my machine right now.

Cool, but we're on MySQL - anything similar available? Percona XtraDB?
Re:Solving the 1+N Query Problem on Tuesday August 25, 2026 @03:25PM (#49439285)
Heavy Hibernate user here, Hibernate does not make it impossible to write N+1 queries afaik - unless there are some tips we're missing in our team?

We just regularly check our slow queries dashboard, fix it (or well let an LLM work on it) and then move on.

Anything similar possible with MySQL?
We run an explicit whitelist, enforced through Microsoft Entra (or was it Intune).

Still no worky for us.
What‘s used instead of MCP in reality? Just REST or other existing API things?

Show HN: Printable Thinking Templates – Mental Models You Fill Out by Hand

I built a collection of one-page printable templates for decisions, prioritization, and reflection. The twist: they're designed to be filled out with pen and paper, not digitally.Why paper? Writing by hand is slow—and that's the point. When I type, I can outpace my thinking. When I write, I catch myself mid-sentence realizing "wait, that's not actually true." The friction is a...

Percona I suppose?
Re:Go Proposal: Secret Mode on Saturday December 13, 2025 @05:01PM (#46258559)
Seems neat, anything similar in Java?
I am mainly working on B2B message exchange, e.g. via AS4/EDIFACT/ebix/CIM files and most parties seem to still work with a lot of batch processing. With the ongoing digitization of e.g. metering hardware and faster settlement times in the energy markets (EU-centric) I think this might not cut it anymore in the future.

Ask HN: Good resources to learn financial systems engineering?

I work mainly in energy market communications and systems that facilitate energy trading, balancing and such. Currently most parties there take minutes to process messages and I think there could be a lot to learn from financial systems engineering. Any good resources you can recommend?

Ask HN: Tips for sensible adoption of AI-tooling in our org?

I manage a team of around 15 devs (small org) and currently some use the built in features of IDEA or GitHub Copilot - basic stuff.I think, also from personally contributing a lot using Claude code, that we could use the tools better and in more areas like for example code reviews. Do you have any tips or strategies on introducing the colleagues in a sensible way to what's out there?

Thanks!

Can you elaborate on the dependent .gitattributes file? Where can I find more information on the necessary content? Sounds super useful!
I want this but self hosted/integrated into our CI (Gitlab in our case).

Show HN: GitHub-native prediction markets using Issues (no DB)

I built a tiny prediction market that lives entirely in GitHub Issues—no external database. Each market is a concrete question about repo work, e.g., “Will Issue #123 be closed by 2025-11-15?” Collaborators buy YES/NO shares to express beliefs, and the price (0 - 1) reflects the team’s collective forecast. This helps with planning, prioritization, and making expectations transparent - without...

Re:High-performance read-through cache for object storage on Saturday September 20, 2025 @03:03AM (#45311132)
Can someone explain when this would be good solution? We currently store loads of files in S3 and directly ingest them on demand in our Java app API pods. Seems interesting if we could speed up retrievals for sure.
We use Gitlab. Is that planned?
Re:I solved a distributed queue problem after 15 years on Tuesday September 09, 2025 @02:53PM (#45186845)
We're a MySQL/Hibernate shop. Anything similar possible with that stack?
Re:Supporting org.apache.xml.security in graalVM on Wednesday August 13, 2025 @10:58AM (#44889320)
Weird coincidence. I work on a software cryptographic module and we worked on this exact same thing today and came to a similar solution.
Re:Broadcom to discontinue free Bitnami Helm charts on Friday July 18, 2025 @04:52PM (#44609703)
Are there any indications or just a feel?
We use es-toolkit to replace Lodash - how would you compare your library?

We just migrated a React app with around 500k LOC and this worked quite well and flawless.

Indeed I do. We run a SaaS in a regulated industry, mainly in Germany. To receive and transmit certain payloads we need to use dedicated TLS certificates from a government run PK infrastructure (Search for "Smart-Meter PKI" if you are curious).

We want to become a sub-CA of this PKI and while we are aware of the policies of this specific PKI, we think that from an engineering or IT ops standpoint we can learn much more from web PKI CAs.

Is there something like this but for Java?
