[Poll]
How many open source projects do you financially support (ie recurring donations of any frequency)?
(If you donate to an umbrella organization with the intent it will support multiple projects on your behalf, I guess probably count that organization as 1 project.)
@andypiper @codepope @hackwimbledon oh :(
Had many nice conversations with him at PostgreSQL events, will be missed.

PGDay UK returns on September 9, and we’re proud to be a Partner-level sponsor. Bruce Momjian, PostgreSQL Evangelist at EDB, will take the stage with his talk “Future Postgres Challenges.” Devrim Gunduz, Bilge Ince, and Floor Drees support the event as volunteers: https://2025.pgday.uk/
The night before, we’re also sponsoring the very first Apache Iceberg™ Europe Meetup at Paddington Central. Miles Richardson will be speaking about the WarehousePG project: https://lu.ma/u042b0vw @postgresuk
@dick_turpin being against things is what the Torry party has done for the last decade.

Do you have complex orchestration issues that you'd like to solve with Podman? Quadlets are now native to Podman and they let you do that! Find out how here! https://blog.podman.io/2025/08/level-up-your-container-game-unified-quadlet-management-is-now-natively-in-podman/ #podman #OpenSource

@amd hmm, but is that not writing 4 copies of the data to the underlying PVs. Which seems a more likely cause of slow performance than it being thin.

An analysis of Github's recent studies on "AI" agents for software development
(Original title: Jussi Pakkanen: Let's properly analyze an AI article for once)
https://nibblestew.blogspot.com/2025/08/lets-properly-analyze-ai-article-for.html
@amd I've not experienced significant performance dip due to thinpool on my setup. Wouldn't have thought the slightly extra metadata of thin provisioning would cause a bit impact.
iostat -mx would be worth a look at to see if your saturating the disk IO and where.
When you say raid 1, do you mean raid 10? 4 disks in a mirror seems odd.
Is the slow IO inside a VM or on the host?
@mntmn looks like it's using an RCA socket with a switched terminal and wiring the switched part to the other channel. I'm guessing, but looks like it's trying to operate in mono if only one RCA plug is plugged in, but in stereo if both are plugged in.

There's a lot talk about "ZeroDisk" infrastructure backed by S3. The pitch is "move your data from locally attached NVMe storage to S3 and your applications will scale easier and be more performant!"
Maybe I'm getting too old for this shit, but I swear to dog this is the 4th such cycle in my career:
1. NFS
2. iSCSI / Fibrechannel
3. Hadoop / HDFS
4. ZeroDisk with S3
Am I the only one that's like: "wait, move TBs of data to S3 from NVMe to increase performance? Are you high?"
It doesn't work, so you scale up. Now you're back to local NVMe "cache disks" running instances as expensive as the locally attached NVMe instances when you add those costs to your S3 bill. The performance is worse because of course it is.
It always comes back to the two hard problems in computer science: naming things, cache invalidation, and off-by-one errors. 😂

House prices ticked up in July, so its time to say again:
House price rises are...
NOT a 'return to growth';
NOT a 'bounce back';
NOT the return of a welcome return of 'health' to the housing market...
HOUSE PRICE RISES ARE ASSET PRiCE INFLATION & ARE CONTRIBUTING TO OUR ONGOING HOUSING CRISIS!
Until we get this message we will never approach removing our housing problems (yes, I know there are other issues for rental rights to loose finance that contribute too)

The best software engineers solve problems, not just write code.
They ask:
- What problem are we actually trying to solve?
- Is this the right problem to solve?
- What's the simplest solution that could work?
- What are the trade-offs?
- How will we know if it's working?
Writing code is the implementation detail. Understanding the problem space, considering alternatives, and thinking through implications—that's where the real value lies.
Code is just the tool. Problem-solving is the skill.

What happened to @till in part shows why billionaires' whims shouldn't control software…
https://ubuntu.social/@till/114932477260801209
Mark Shuttleworth once shouted that “Software Freedom Conservancy is just like Microsoft” & publicly stated I was a “McCarthyist” for enforcing #GPL. Like most billionaires, he says & does whatever he wants & faces no consequences.
You are far from the only employee he has mistreated & most go on to do their greatest work after leaving Shuttleworth's company. I'm sure you will too.

Urgent help for OpenPrinting needed!
As many here know, I am co-founder and lead of OpenPrinting since 2001, known as the print guru for Linux and free software by many. I also got one of the 8 fellows of the Linux Foundation for this.
Up to now I was working at Canonical, hired back in 2006 just to run OpenPrinting and also to maintain printing-related Ubuntu packages.
... 🧵
Please boost.
