PocketBook is by far the most hackable, especially their b/w readers, which still run Linux 3.10 because of hardware limitations - for these, getting root permissions is trivial with an old jailbreak script based on Dirty COW. (That said, the hardware is rather slow for the price tag.) Most applications use modern Qt 6 / QML. You won't find much information online, but it's a lot of fun exploring all this stuff with Ghidra MCP and creating binary patches. Shameless plug: I created an emulator so that you can download firmware from the official support web page and try it out on a Linux desktop (https://codeberg.org/datyoma/pbemu)

IMO the actual difference between introverts and extroverts is that the latter use @here and @channel a lot more frequently

...or Korg NTS-1 (or even both together), which is not as modular but fun and hackable in its own way

New comment by lomereiter in "The Raspberry Pi 5 Is No Match for a Tini-Mini-Micro PC"

lomereiter — Sun, 16 Jun 2024 16:18:25 +0000

For some Mini PCs there are fanless cases, e.g. from Akasa: https://akasa.co.uk/update.php?tpl=list%2FCHASSIS+POWER.tpl&...

I've got one of those, and it houses a system with 8 CPU cores, 32 GB RAM (can be upgraded to 64 if need be), 1 TB NVMe and 4 TB SSD - and it's all inside, whereas with an RPi the SSD would have to be external. The only thing that's collecting dust now is the old RPi.

The community can agree to always call it "Redpanda Connect™ (former Benthos)"

Don't you ever get inspired by reading good books? You can learn new tricks and apply them elsewhere, and it's much easier than actually contributing to a big open-source project.

If this were indeed the average attitude, there wouldn't be this big of an outcry with regards to the move from fully open-source to source-available licenses (Mongo/ELK/Hashicorp/etc.)

FWIW I had decent success with Xpra on Linux, and it's still being actively developed, e.g. the HTML5 client is considered stable now: https://github.com/Xpra-org/xpra/

lomereiter — Sat, 02 Mar 2024 16:49:20 +0000

"Large teams" is the key, there has to be enough services and/or language diversity to justify the extra complexity.

New comment by lomereiter in "K8s Service Meshes: The Bill Comes Due"

lomereiter — Sat, 02 Mar 2024 11:46:26 +0000

To set up an open-source service mesh, the infra team anyway has to configure a private certificate authority and cert-manager to create k8s secrets for the service mesh components. From there, it's straightforward to extend the common deployment template (hopefully there is one) to mount a volume with an auto-rotated certificate. All an application developer has to do is to use that certificate, which is much less effort than what you are implying.

Reminds me of a Russian joke.

A secretary applies for a job; the interviewer asks her: "In your CV you claim that you can type 1000 characters per minute - for real?!" "Yes!", she replies, then adds in a low voice: "but such nonsense comes out..."

Arrow format is not intended for storage, it's for in-memory data exchange between different libraries and languages.

Glad to see usability improvements here, but I won't be using it until there's a light theme (asking an application to respect the OS theme is apparently too much these days).

You could buy a USB enclosure for an M.2 NVMe SSD - a bit bulkier but still portable and addresses your concerns.

New comment by lomereiter in "Choose Postgres queue technology"

lomereiter — Mon, 25 Sep 2023 10:44:04 +0000

This article was written in 2015, a year before idle_in_transaction_session_timeout parameter was added (in Postgres 9.6) - which is unfortunately still disabled by default, but that's the easiest way to make sure no transaction sits idle for too long.

lomereiter — Mon, 25 Sep 2023 10:36:52 +0000

Yes, you absolutely need to set a reasonable idle transaction timeout to avoid a disaster (bugs in the code happen) - this can also be done globally in the database settings.

Better yet, oauth2-proxy in case of an organization: only admins need to know the secrets, every user simply uses SSO to get access.

lomereiter — Wed, 17 May 2023 06:19:18 +0000

We ran into a similar issue once, and addressed it by changing the sorting column from id to created_at which has the same ordering but doesn't have an index on it. Good to know Postgres optimizer can be tricked even easier.

Our industry is so disorganized that after half a century 'Software Engineer' is still not a recognized profession, and there is just as little interest in unionizing. I lack the audacity to make sweeping judgments about it.
