JakaJancar··on Updates to Full Disk Access in macOS
Just use an iPad?
JakaJancar··on Timeline of the OpenAI accidental attack against Hugging Face
I’m optimistic about this. A system with these agents rummaging around for a while will be much more secure than one without.

We’ve learned security through obscurity is bad. Not using these will be security through ignorance.

Hopefully it will push us to not only fix individual issues but close entire classes of possible gaps, once P(discovery) gets much higher.

JakaJancar··on Run Kimi K3 using 29 GB of RAM at 0.50 tok/s
Love that it’s embeddable, I needed exactly this for the upcoming app I’m shipping!
JakaJancar··on You Just Reveived
I have a phone number that is +1(gapless non-decreasing sequence). I’m entertained every week by developers testing.

(Also, people using it as a fake number for some appointment/reservation - which I sometimes update to change their name or add a special request :))

JakaJancar··on OpenAI has deleted the word 'safely' from its mission
I don’t think OpenAI gets enough credit for exposing GPT via an API. If the tech remained only at Google, I’m sure we would see it embedded into many of their products, but wouldn’t have held my breath for a direct API.
JakaJancar··on Apple, What Have You Done?
Ah yes, Linux on a laptop: wifi, sleep, graphics - pick any two
JakaJancar··on What has Docker become?
They enshittified/Dropboxified their core Docker Desktop app so much that OrbStack — I believe a single person initially — managed to build a better product. I love this outcome.
JakaJancar··on A first look at Django's new background tasks
Procrastinate does have scheduled tasks but maybe I’m missing some other part of beat you mean (never used celery)
JakaJancar··on A first look at Django's new background tasks
Assuming you're fine with keeping the queue in postgres, I've used Procrastinate and it's great:

https://procrastinate.readthedocs.io/en/stable/index.html

Core is not Django-specific, but it has an optional integration. Sync and async, retries/cancellation/etc., very extensible, and IMO super clean architecture and well tested.

IIRC think the codebase is like one-tenth that of Celery.

JakaJancar··on Speed: Engineering Airbyte's 4-10x Performance Breakthrough
The "Unix Domain Sockets breakthrough" sounds kinda suspect to me. I'd imagine you should be able to push at the same rate to stdout with a smart MPSC design.
JakaJancar··on I caught Google Gemini using my data and then covering it up
I didn't mean to imply Google was covering anything up, but Gemini in this specific conversation clearly was.
JakaJancar··on HTTPS by default
You have some weird definition of "root".
JakaJancar··on What’s New in PostgreSQL 18 – a Developer’s Perspective
One obvious thing I still can’t believe pg doesn’t have is the ability to define triggers at the database or schema level. I must have written code to mass generate DROP/CREATE TRIGGER probably 5 times (yes I know you can reuse the trigger procedure itself). And then you need to remember to re-run whenever tables are added/removed.
JakaJancar··on Apple has a private CSS property to add Liquid Glass effects to web content
I often suspect things in Settings, esp. account/iCloud section to be webviews, just based on how they load (icons appearing a short moment after the page opens for example).
JakaJancar··on Ask HN: Why would a CA revoke a cert with a public private key?
Makes sense, thanks!
JakaJancar··on Ask HN: Why would a CA revoke a cert with a public private key?
HN comes through in 10 min :)

I didn't know about CA/Browser forum and the Baseline Requirements. Thanks, will check it out!

JakaJancar··on Show HN: Konty – A Balsamiq-alternative lo-fi wireframe tool for modern apps
Love it!

I always liked Balsamiq, it really forces you not to obsess about the pixels too much, but it was so slow/bloated/buggy, like something from the Java on desktop era. This is much smoother!

JakaJancar··on People who are colorblind are less likely to be picky eaters
That makes sense. I would guess if you're completely blind or can't smell or taste, you're less picky too. And if all of the above, you're not picky at all.
JakaJancar··on Show HN: Assertly – scriptable monitoring for infosec, IT, compliance, DevOps
Haha, thanks. It seems we share a pet peeve. I assume you know https://sso.tax.
JakaJancar··on Show HN: Assertly – scriptable monitoring for infosec, IT, compliance, DevOps
If AI can code anything, it should certainly be these small scripts. This is the current area of exploration.
JakaJancar··on Show HN: Assertly – scriptable monitoring for infosec, IT, compliance, DevOps
Pingdom (original), Checkly, etc. are for monitoring your websites, from "outside", with a focus on availability (super frequent checks, from different geos, ...).

Datadog, New Relic, Pingdom APM, etc. are for monitoring your production environments, from "inside", deeply integrate with your code, with a focus on availability and troubleshooting (stack traces, distributed tracing, ...).

Assertly is for monitoring of your systems (production, or custom in-house internal, or licensed SaaS) and making sure they behave in a way they're supposed to, with a focus on security, integrity, compliance (more complex, customized checks that run for example daily).

JakaJancar··on Every Way to Get Structured Output from LLMs
AI noob question:

Why do OpenAI/Anthropic/... not support constraining token generation? I'd imagine producing valid structured output would be at the top of their feature request lists.

JakaJancar··on React 19 Breaks Async Composability
Ah, cool, didn't know - joined the train late.
JakaJancar··on React 19 Breaks Async Composability
I've adopted the practice of avoiding libraries with major version > ~3. If you needed to re-design your API so many times, I don't trust your judgement enough to build on top of it.

That said, I still use React and... it's at 19.x :'(

JakaJancar··on Safari 18 can automatically transition users to passkeys [video]
The lack of export scares me too, but is it really a problem?

If I were to switch to Linux, I guess it just means that I'd have to go through the forgotten pass(key) flow on every site on first login?

JakaJancar··on Vulkan1.3 on the M1 in one month
Maybe an edge-case in some codegen?
JakaJancar··on Priced out of home ownership
I lived in the West Village for the last 6 years, also facing the courtyard and maybe seeing 20 apts, pretty much all consistently utilized

¯\_(ツ)_/¯

JakaJancar··on Passkey Implementation: Misconceptions, pitfalls and unknown unknowns
The use case is that I’m an Apple/iCloud user and want to migrate to Google/Linux/whatever and don’t want to go to 100 sites manually to change my passkey?
JakaJancar··on HTTP/3 adoption is growing rapidly
One thing where the semantics are not the same between HTTP/1.1 and HTTP/2/3(?) is the `Host` header, which is often (always?) gone in the latter in favor off the `:authority` pseudo-header.

Apps/scripts may rely on `Host`, but the underlying HTTP/2 server software might not normalize/expose it in a backwards-compatible way (e.g. Hyper in Rust).

Technically I guess it’s the browsers fault it doesn’t set it.

I would be curious to know if there are other such discrepancies that apps migh run into when enabling HTTP/2/3.

JakaJancar··on Car showed pop-up while driving
Well his username is bad_user :)
