I been using MiMo-V2.5 to do most of my work as software engineer, on a variety of projects I'm working on, and I been VERY happy with ROI. The model is very powerful! Not perfect – I've run in hallucination loops once or twice, but nothing a stop-then-continue wouldn't solve.

The cost is unbelievably low, and the quality of intelligence I get is equivalent to when I was working mostly with Anthropic models (late last year/early this year). I'm fully invested in MiMo and I'm very happy with it.

-- PS: I also check almost daily to see if other models are capable of doing such great work. And they do – DS4F is powerful and DS41 is impressive, GLM 5.3 Flash gets a job done well, etc. – but when I add cost of M-token in the ROI math, Jeez! MiMo is an order of magnitude better.

Unrelated to the post – but if you're trying to build smt that "magically syncs" across devices, you'd like to use CouchDB (and it's front end companion, PouchDB). They solve this problem for you, and it's solved in a very, very reliable way for years!

FWIW, search [and research] about offline-first apps. Lots of gems in this niche!

It's wonderful to see people trying to fork SQLite in any way possible, to supposedly build a better product with AI, out of smt that's been built by seriously talented people for over 20 years.

Kudos to the team behind SQLite. These people built smt absolutely amazing!

OH GOSH! I remember VERY WELL the promises from Internet.org which, in fact, turned to be Meta, Microsoft, and some other big techs teaming up to build walled gardens up to today's people thinking that "Internet" resumes to just Facebook and Instagram.

So, Ahthropic pirated god-knows-how-many books from all around the world to build Claude models, launches multi-billion products out it, and then gets fined $1.5B. Sounds like the crime was worth the shot.

It reminds me of:

"Building for the future"... then, "we're firing 1K+ people."

What a BS.

So you're saying it's pretty low quality because it failed specifically to parse PDFs?

IIRC, multiple writers in SQLite is supported, their writes will just be serialized. What you don't have is concurrent writes. But, given SQLite writes are so fast, in practices it's not really a big deal.

If you haven't used SQLite in a real project with heavy writes, I'd say you do it. SQLite is WAY more powerful than people tend to think of it.

THANK YOU VERY MUCH you and the team behind OpenPrinting for such GREAT contributions to Linux - and so to the Humanity itself!

New comment by joelwallis in "SQLite as an Application File Format"

joelwallis — Fri, 28 Nov 2025 16:09:56 +0000

SQLite is abolutely amazing as an app format! I couldn't list how many tools are available to read SQLite data, or how easy and friendly they are. Even its CLI does wonders when you're dealing with data with it. SQLite has been around for 20+ years and is one of the most heavily tested softwares in the world.

SQLite is very simple, yet very reliable and powerful. Using SQLite as file format might be the best decision an engineer can take when it comes to future-proofing preservation of data.

I wouldn’t say it’s so intuitive. We need more of these articles coming in — I learned nice things from this text, specially about the exact match over partial indexes, and to always QUERY EXPLAIN instead of assuming you’re right (my case haha).

What’s obvious for you might not be for someone else.

I could do it with Photoshop, two candles of Red Bull and a 5K USD payment in my account.

Jokes apart — this is the best SciFi movie ever! It’ll become one of these movies one’s got to rewatch every 5y or so.

New comment by joelwallis in "Ask HN: Where can I live off 1k USD per month?"

joelwallis — Tue, 31 Aug 2021 00:27:36 +0000

You can definitely live in Brazil with 1K USD/month.

And nowadays it's even better because the USD-BRL rate is about 5-something. For a comparison, 1K USD is about what I spend every month to live - and I definitely don't cook beyond just breakfasts and some snacks/sandwiches. So I lunch in restaurants every single day, I live in a quite comfortable apartment, etc. - I mean, I'm not "stretching myself to spend as minimum as possible". In fact, 1K USD is about 4x the BR minimum wage, and about 2-3x the "common" income of people.

I live in Fortaleza, a very sunny city which is close to some incredibly beautiful beaches. Search for "jericoacoara" on Google and you'll know what I'm talking about (Jeri tends to be a bit expensive tho, due to heavy presence of tourists - but not much).

Fun fact: it's quite common to hear about gringos coming around and deciding to stay. You'll find some French and Italian restaurants in Jeri and/or Jijoca - and lots of gringos, of course.
