Wait, you push straight to main?

Wait, you let _Claude_ push your e-commerce code straight to main which immediately results in a production deploy?

SQLite has a ".backup" command that you should always use to backup a SQLite DB. You're risking data loss/corruption using "cp" to backup your database as prescribed in the article.

> Would We Choose SQLite Again? Yes. For a single-server deployment with moderate write volume, SQLite eliminates an entire category of infrastructure complexity. No connection pool tuning. No database server upgrades. No replication lag.

These are weird reasons. You can just install Postgres or MySQL locally too. Connection pool tuning certainly isn't anything you have to worry about for a moderate write volume. You don't ever need to upgrade the database if you don't want to, since you're not publicly exposing it. There's obviously no replication lag if you're not replicating, which you wouldn't be with a single server.

The reason you don't usually choose SQLite for the web is future-proofing. If you're totally sure you'll always stay single-server forever, then sure, go for it. But if there's even a tiny chance you'll ever need to expand to multiple web servers, then you'll wish you'd chosen a client-server database from the start. And again, you can run Postgres/MySQL locally, on even the tiniest cheapest VPS, basically just as easily as using SQLite.

The fix appears to nicely asking the forgetful unreliable agent to please (very closely pretty please!) follow the deploy instructions (and also please never hallucinate or mess up, because statistics tells us an entity with no long term memory and no incentive to get everything right will do the job right 99.99999999% of the time, which is good enough to run an eshop) not deploy too often per hour.

With one simple instruction the system (99.9999% of the time) gains the handy property that “only” two processes end up with the database files open at once.

Thanks for the vibes!

More simply:

    ╭──────────────────────╮
    │ typeof('{a:1}'->>... │
    ╞══════════════════════╡

I took three weeks off from tech, read books from last century, and travelled Europe. Coming back, reading LLM generated content and code feels like nails on a chalkboard. Taste, it does not have taste.

The sequence shows 3,700+ (every task ever created). If those numbers diverge unexpectedly, something deleted rows it shouldn't have.

Or it means that SQLite is exhibiting some of its "maybe I will, maybe I won't" behavior [0]:

> Note that "monotonically increasing" does not imply that the ROWID always increases by exactly one. One is the usual increment. However, if an insert fails due to (for example) a uniqueness constraint, the ROWID of the failed insertion attempt might not be reused on subsequent inserts, resulting in gaps in the ROWID sequence. AUTOINCREMENT guarantees that automatically chosen ROWIDs will be increasing but not that they will be sequential.

> No ILIKE. PostgreSQL developers reach for WHERE name ILIKE '%term%' instinctively. SQLite throws a syntax error. Use WHERE LOWER(name) LIKE '%term%' instead.

You should not be reaching for ILIKE, functions on predicates, or leading wildcards unless you're aware of the impacts those have on indexing.

If you're using strings embedded in JSON as predicates, you're going to have a very bad time when you get more than a trivial number of rows in the table.

please consider writing it yourself. quirks in human writing is infinitely more interesting than a next-token-predicted 500 word piece

I think SQLite is fantastic but it does start to fall apart at the edges sometimes.

What is more interesting to me is the fact that everyone seems to think of Postgres as the obvious alternative to SQLite. It is certainly an alternative. For me, the most opposite thing of SQLite is something like Oracle or MSSQL.

The complexity being relatively constant is the part I care about most here. Running a paid, COTS database engine on a blessed OS tends to be a little bit easier than an OSS solution that can run on toasters and drones. Especially, if you are using replication, high availability, etc.

The business liability coverage seems to track proportionally with how much money you spend on the solution. SQLite offers zero guarantees accordingly. You don't have a support contract or an account manager you can get upset with. Depending on the nature of the business this could be preferable or adverse. It really depends.

For serious regulated business with oppressive audit cycles, SQLite trends toward liability more than asset if it's being used as a system of record. That it merely works and performs well is often not sufficient for acceptance. I'm not saying that Postgres isn't capable of passing an intense audit, but I am saying that it might be easier to pass it if you used MSSQL. The cost of having your staff tied up with compliance should be considered when making technology choices in relevant businesses.

If the problem is excessive deployments via GitHub Actions, why not use concurrency control on GitHub Actions ( https://docs.github.com/en/actions/how-tos/write-workflows/c... ) instead of relying on agent randomness and the hope that it won't make the same mistake again? Am I missing something?

> embarrassingly simple

This is becoming the new overused LLM goto expression for describing basic concepts.

SQLite is a rock solid piece of software that offers a great value prop: in-process database. For locally running apps (desktop or mobile), this makes perfect sense.

However, I genuinely don't see the appeal when you are in a client/server environment. Spinning up Postgres via a container is a one-liner and equally simple for tests (via testcontainers or pglite). The "simple" type system of SQLite feels like nothing but a limitation to me.

The LLM prose are grating read. I promise, you'd do a better job yourself.

I don't know if it's just me, but this whole post seems to have time traveled forward from about 3-4 days ago.

It's not just a repost. The thread includes a comment I made at the time which now from "1 hour ago".

Makes me wonder if it's an honest bug or someone has hacked the hacker news front page to sell their t-shits, mugs, and AI starter kits.

I see tons of articles like this, and I have no doubt sqlite proved to be a great piece of software in production environments, but what I rarely find discussed is that we lack tools that enable you to access and _maintain_ SQLite databases.

It's so convenient to just open Datagrip and have a look at all my PostgreSQL instances; that's not possible with sqlite AFAIK (not even SSH tunnelling?). If something goes wrong, you have to SSH into the machine and use raw SQL. I know there are some cool front-end interfaces to inspect the db but it requires more setup than you'd expect.

I think that most people give up on sqlite for this reason and not because of its performance.

I've a busy app, i just deploy to canary. And use loadbalancer to move 5% traffic to it, i observe how it reacts and then rollout the canary changes to all.

how hard and complex is it to roll out postgres?

> The Fix: Stop Deploying So Fast

I don't know how Ultrathink works, and I have no "real world" experience with Kamal, but I find it intriguing to see someone consider 11 deployments in 2 hours to be "fast".

Instead of handicapping yourself, fix your deployment pipeline, 10 min deploys are not OK for an online store.

A well designed system shouldn’t drop orders?

If you perform at least once processing then use Stripe idempotency keys you avoid such issues?

I use SqLite for a small hobby project, fine for that. Wanted to read the article to see why I should not, but it attacked me with a "subscribe" popup, so I stopped there. The comments here seem to be based on daydreaming on scaling to a lot of users who need 24/7 uptime, which is not always the case.

> Yes. For a single-server deployment with moderate write volume, SQLite eliminates an entire category of infrastructure complexity. No connection pool tuning. No database server upgrades. No replication lag.

None of these is needed if you run sqlite sized workloads...

I like SQLite but right tools for right jobs... tho data loss is most likely code bug

I still haven't figured out a good way to due blue/green sqlite deploys on fly.io. Is this just a limitation of using sqlite or using Fly? I've been very happy with sqlite otherwise, rather unsure how to do a cutover to a new instance.

Anyone have some docs on how to cutover gracefully with sqlite on other providers?

> Backups are cp production.sqlite3 backup.sqlite3

I use gobackup[0] as another container in compose.yml file which can backup to multiple locations.

[0]: https://gobackup.github.io/

Am I the only one finding this article highly suspect? It seems like the errors made are so basic, i.e. using the wrong SQL dialect for the db system in use, and there orders were apparently only at 17?

could have used firebird embedded, also a simple deployment such as sqllite, but better concurrency and more complete system, also a tad faster

You should use Shopify and focus on the store part of the business, not the SQLite part :)

If Nico send him an email. The AI CEO should take his offer.

How the hell did this get so much engagement, let alone as a repost? Is "SQLite" in the title really all it takes? This site was registered 8 months ago, the whole blog started in February, the first post declares its writer to be an AI CEO, most posts are about hiring and managing other AI agents, it claims to sell everything from coffee mugs to services from itself to also be the CEO of your business. This feels more like performance art than a business. There's no evidence they've sold anything or even have any actual inventory. AI agents can't build you a warehouse or manufacture physical goods.

You guys are arguing with a bot, in a way almost arguing with yourselves, as it may very well not have actually done any of this, is definitely not running a "real store," and is seemingly publishing posts that are a parody of Hacker News style founder journeys but if the founders were bots.
