Show HN: Celery observability inside Django admin (no Flower, no extra process)
by yassi_dev | 2026-01-21 13:18:16+00:00
I built an open-source tool that surfaces Celery inspection data directly inside Django admin.

The motivation was avoiding a separate Flower process and keeping operational context where Django teams already work. It uses swappable backends that support django-celery-results or even the celery inspect API directly for live communication with workers

Feedback is welcome, especially from teams running Django + Celery in production.

This is the third in a series of projects that bring observability to the Django admin. You can check out the others as well:

Hi HN,

OP here. I got tired of subscription-based tools just to add a nice background and padding to my code screenshots.

I built Velox Snap as a simple, lightweight alternative.

Privacy focused: It runs in the browser, no image uploads to servers.

No monthly fees: It's a simple HTML/JS template.

Fast: Instant export to PNG.

I usually sell it for more, but I dropped the price to $1.50 today (coffee price) to get some initial users and feedback.

I believe simple tools should be a one-time payment, not a SaaS.

Let me know what you think!

I agree the cause is at least partially structural but I'd argue that congress deadlocking is generally an intentional feature not a bug. Meanwhile the courts on the whole seem quite reasonable to me. Disliking what the rules say should never turn into lambasting the ref for making calls consistent with those rules.

That said, it doesn't seem to me that reform has been meaningfully attempted yet. It isn't reasonable to blame the establishment for blocking a reform that never got organized to begin with.

Presumably if there were concrete proposals with broad popular support intended to fix lobbying, gerrymandering, first past the post, and the information environment in general then we should see them implemented at the state level here and there. But we don't.
Show HN: Trading cards for learning – 16 albums, 2.7k cards, learn by collecting
by Manuel_TPC | 2026-01-21 13:19:30+00:00
Hey HN! Solo dev here.

I spent a year building this because I learn best when knowledge stacks visually. Traditional trivia is forgettable—this uses collecting psychology to make it stick.

How it works:
- Answer questions correctly → unlock illustrated cards
- Use cards you've collected as hints for harder questions
- Knowledge builds on itself, like learning should

Right now: 2 fully playable demos (AI History, Streaming Wars) + 14 more albums in progress.

Background: I'm a robotics engineer turned neuropsychologist. This merges what I know about learning retention with gamification mechanics.

16 albums planned:
AI • Streaming Wars • NFL • K-Pop • Marvel vs DC • U.S. Presidents • National Parks • eSports • Fast Food History • Blockbuster Cinema • Revolutionary Inventions • Books That Changed the World • Urban Mysteries • Women in Sports • American Painting • Music Journey

2,733 cards total. Building 5-8 cards/day.

Try the AI demo: https://tradingpicturecards.com/aia/

Feedback very welcome. What would make you actually use this?

There are tables at $dayjob with both (begin, end) and also (incept, expire) fields. It's "on such-and-such date, X was true", but also allows for "as-of Z date, we believed that...".

Also you can have most data being currently unused even without being flagged deleted. Like if I go in to our ticketing system, I can still see my old requests that were closed ages ago.

> - Standardized investment documents

All investments I took part of implied a lot of back and forth on conditions adapted to the specific case, preferences, fears, etc. I have doubts that "standardization" can be reasonable achieved here.

> - Standardized EU-wide stock options

EU does not have attributions on tax, it's the national governments that do (see https://european-union.europa.eu/priorities-and-actions/acti...).

The issue with stock options are that they are taxed, so you will have to consider each country in particular.

Maybe you would like for EU to have tax responsibilities, but I wouldn't jump to that without thinking about the implications. As an example the Euro monetary union without a fiscal union can causes issues already (for some explanations check https://en.wikipedia.org/wiki/Fiscal_union).

Yes in practice I've done fairly simple tasks using AMP at work and ended up with bills of 100-150$ for them which is somewhat less (but similar order of magnitude) as contracting out to LCoL countries. Depending on how the technology (towards cheaper cost) and financial situation (towards profitability and higher costs) evolve, it wouldn't be shocking to me that the frontier model end up more expensive than human contractors.

"Back when I was a Catholic-school kid in northern Wisconsin, my school lessons briefly focused on the metric system. This was in the late 1970s."

Man, the progressive school (Comanche Elementary in Overland Park, Kansas!) must have had a huge impact on my life. In addition to open classrooms (I was in Unit 5, not 4th Grade), team teaching, a focus on experimental science, a circular layout to the school with a sunken (architecturally) library in the center…

Yeah, we went over the Metric System that whole year. I can still sing the "Metric Family" song from the film on metric units ("Kilo", "Milli", etc.). And to my young and impressionable mind, the U.S. was joining the rest of the "Free World" in a kind of Star-Trek-like casting aside of the old things that divided us—joining each other with a focus on progress, science, space…

President Carter came along around the same time or shortly after. And I have a photo of a family road trip to South Dakota, Montana: the sign that indicates the altitude of a particular mountain pass has both feet and meters. I Google-mapped the same location recently and of course it's no longer in meters.

I feel like in my elementary school days (the 1970's) the U.S. was on the cusp of a future of optimism—no doubt buoyed by having put astronauts on the Moon, but I was wildly on board for it.

But then some kind of shit seemingly started to poison the country. I don't feel we have ever returned to that level of national optimism. Perhaps 1976, the Bicentennial, was the end of it. (Recently watching the film "Nashville" brought me back a bit of the vibe of the times.)

I've been missing it my entire life since.

That’s not what I’m saying at all. I’m saying that a system where the majority of air temperatures in the vast majority of the country fall between 0 and 100 is slightly more convenient than one in which they fall between -17 and 37. 0 is really cold it doesn’t frequently get colder than that in most of the country. 100 is really hot, in most places it doesn’t get hotter than that.

Feet are slightly more convent for declining human sized things because meters are just a little too big to describe human height and centimeters are a bit you

If you were designing a system to describe humans with no other consideration you’d probably pick one where 10 units was the average human height. And feet is closer to that than meters. Also you can divide 12 by 6 and 3.

I’m not saying that customary is superior just that it does has certain advantages.

In MSSQL Server part of the plan match is the various session/connection options, if they are different there are different plans cached.

I believe the plan data structure PG is intimately tied to process space memory addresses since it was never thought to share between them and can even contain executable code that was generated.

This makes it difficult to share between processes without a heavy redesign but would be a good change IMO.

As a Dutch person I never understood this push until someone told me (and this is true in 2026!!!) that if you open a LLC (Gmbh?) in Germany you have to physically go to the notary and have a person READ OUT all the statutes to you.

The whole process including banks accounts etc... can apparently take months in total.

Personally I would not create "EU-INC" but just make all local entities legal in every country. Then countries could compete to be the best system to attract companies and entrepreneurs.

That’s funny because when I work with Fahrenheit I just work with 5°F ranges to compensate for the approximate mental math required. Eg very quick mentally, 100°F = 37.778 °C (thanks autocorrect) = (100-32)/2 = 34.

But if it was closer to freezing say 42°F =5.556 °C (again) so 5°C. So arbitrarily we could say 57°F was 12°C =53.6 °F actually.

But a true Canuck knows knowing the temp is barely half the battle, what’s the wind speed and humidity? 29°C can be a lovely day if it’s dry or completely unbearable if it’s humid.

We hardly ever use decimals for weather-related measurements, the other factors above being more relevant.

Contrast that with measurements where I would say if you need to know a precise one you should be using decimal; ie what do you do if it doesn’t precisely third or fourth? If you’re talking about tool sizes then any system works as long as your froodle matches the grommlet.

It is not, you guys are talking from a specific american ISP perspective where you have these modem+router+gateway+firewall combo devices. Not everyone gets that.

Many get just a modem and buy a cheap router which may not have a firewall. MANY more get just a modem and their laptops are directly exposed to the internet (!!!), those you can't do much about, but many put a "router" that's just a cheap wifi access point with layer 3 routing and NAT. If you chose to "bridge" a device (like those internet exposed laptops) or port-forward, it will just work (even with ISP routers!!) there is no firewall rule change required.

I've worked in this space supporting consumer grade routers, and then worked in enterprise networking. But don't take my word for it, you all can take a trip to shodansafari, how many devices are listening port 3389 and 445 with consumer grade laptop names?

But it isn't a popular thing to say for whatever reason. I guess IPv6 is a political ideology now lol.

Thanks for your response sir! and I have had such a project where I feel like such depth can be provided.

Much of what I try to build is for my own difficulties/curiosities so this works perfectly for me!

I do have a question and I am interested if you can answer but does there have to be a single aha moment or can there be a multiple of aha moment which can build something enjoyable (atleast to me)

I don't know if it counts as promotion and sorry about that but in this comment here but like how I first went from building a yt extension for screenshot (I watch youtube lectures for studies and slides can change and I wanted to make a screenshot tool which can take photo of 2s or x seconds ago) store it in a folder and have a tool which can auto generate a slideshow of sorts with all new pictures and pdf/laser tool as well.

A lot of these were just when I had created the snapshot tool, I went into deeper and deeper because of curiosity.

Now firstly I am not sure if this is a unified tool, its 3 different products and much of the code was actually generated in less than 3 hours individually but let's say I had to connect the dots and build on them on what I feel like I can do better and better about it & added like this.

Now I don't know if this is worth a show hn given its 3 different products mashed together for my own use case. but supposing if it was one product with continuous aha-s but the original prototype was built in 3 hours as you mention, would it still be considered depth/substance (supposing that they actually give the product after multiple aha's and not just after one because at that point even to me it does feel like there is virtually no difference between that and the resume idea you mentioned)

Would Hackernews be more interested in something like this? Because I sometimes show HN when my project's the 3 hour thing but I still use it myself and build upon it and continue doing so and if I feel like I can have multiple aha's in my project, do you feel like it passes the substance test that HN is looking out for?

If so that's the case, So the feeling I get from this is that I can deploy it in a more tightknit community first (thinking a discord server) /personal use/friends, then slowly build it and once the project has had a decent bit of thought put into it, I can add a show HN article?

Because I just prototype and keep on growing what I feel like I would personally want but in most cases, there really isn't a single aha but continuous of small aha's :)

Haha, well I hope these gymnastics aren't actually fooling you, of all people. That'd be a major concern.

You can rest easy knowing they're not fooling anyone else though.

Just a few points of note:

* You mention Trump wanted the activist deported, and they were arrested in the street, but they apparently WERE NOT also detained or hunted? How did they find an activist based on an order from on high, if not by hunting them? How could they possibly deport someone without detaining them first?

* You describe this person as an activist, and federal officials have described the enforcement action as based on her activism. You can go ahead and read the 1st Amendment if you need a refresher, but "activism", and certainly signing an op ed, is protected speech, thus proving my original point.

* With regard to what substantiates the judge's opinion, you can go read the court filings, duh. Do you need page numbers for this one too?

* "She's approached on the sidewalk and, in the AP's words, "detained"." LMAO. I love the scare quotes ;)

* Re 4A/warrants/arrests, etc. Arrests can be made in lieu of warrants only in exigent circumstances (which no immigration stop qualifies as), and they can never be made in lieu of probable cause. I think your motivated reasoning might be affecting your reading comprehension on this point.

Maybe the CRC32 implementations in the smasher suite just aren't that fast?

[1] claims 15 GB/s for the slowest implementation (Chromium) they compared (all vectorized).

> The 32 bit hash of CRC32 is too low for file checksums. xxhash is definitely an improvement over CRC32.

Why? What kind of error rate do you expect, and what kind of reliability do you want to achieve? Assumptions that would lead to a >32bit checksum requirement seem outlandish to me.

As I explained elsewhere in this thread, the results here are more like trying to launch a rocket to the moon, unleashing AI on the problem, and settling for some kind of giant firecracker as a POC.

This isn't a POC web engine; it's throw-away code that can never scale to a full web engine.

So instead of wasting millions on this autonomous run, they should have put together a small team of people with some ideas on how to improve on existing web engines, and then give that team a large token development budget. You could get a nice POC after a couple of weeks, and after a year or two of further iterations you might have something really interesting.

So this is a great example of how AI fails when left unsupervised; a more interesting experiment would be about how a small team can leverage AI to leapfrog Chromium; not in one week but in a year or two.

The SE has a minimum capital requirement of 120k € so is not within reach for most people. I think this EU-Inc would be a simple structure with a lower threshold.

I am absolutely for it. There are too many different types of company structures in the individual EU countries and they don’t work well when you move and come with all sorts of different risks. Obviously many are also just cumbersome to start and dissolve. You could start five US LLCs within ten minutes of filling out some online forms whereas to start one European entity depending on the country you might have to make a notary appointment, register with the national registry and the tax authority. I think there’s a lot of room for improvement which can take days to weeks.

Show HN: Oauth2-forwarder – web oauth2 for dev containers
by sam256 | 2026-01-21 13:26:00+00:00
tl;dr - typing /login in claude code in a docker container will do auth in your host's browser :)

My team and I develop almost exclusively in dev containers. If you initiate an oauth2 auth from inside the dev container (for claude, azure cli, etc) you either (a) have some annoying copy and pasting to do or (b) you are using VS Code which magically makes it work with your host browser.

This utility makes the VS Code magic into a standalone utility so you don't need to be using VS Code but still get automatic proxying of your oauth2 requests to your hosts browser.

The basic idea (which is what VS Code does under the hood I believe) is to set up a server<->client relationship between host<->container that grabs your container-based cli tools browser open request, forwards out to the host, does oauth, forwards it back into the container.

We've been using it for a while and it works great. Thought I'd share.
Show HN: Client-side Google Location History visualizer
by Beefin | 2026-01-21 13:26:02+00:00
I built a browser-based tool to visualize Google Location History after they moved
Timeline data to on-device storage, making it harder to view your own data.

Demo: https://ethan.dev/utilities/location-history-visualizer

Key features:

• 100% client-side – your data never leaves your browser

• Supports new location-history.json format (from Google Maps app export)

• Also works with older Google Takeout formats (Records.json, Semantic Location History)

• Interactive map with Leaflet.js, customizable styling, PNG export

• No signup, no analytics, no tracking

Technical details:

- Uses Leaflet for mapping, dom-to-image for exports

- Parses multiple Google Timeline formats (they've changed it 3 times)

- Handles the new "geo:lat,lng" coordinate format

- Date range filtering, fullscreen mode, style customization

Why I built this:
Google's Timeline migration to on-device storage broke web access. You can export
from the Maps app (Settings → Location → Export Timeline data) but there's no easy
way to visualize it. This tool runs entirely in your browser with zero server
interaction.

The code handles visit objects (places you stayed) and activity objects (routes
between locations), showing semantic labels like "Home" and confidence scores.

Open to feedback on the parser logic – Google's format isn't well documented.

This would require a significant culture change, much bigger then what happened post zero interest era.
For now rainmakers are still praising the ability to spew bullshit.
See the recent ralph debacle. Theo this week praising someone for running 50 active "projects" with zero users.
Tobi Shopify CEO shitting out dummy projects.
Linus vibing side projects.
The thrill of seeing a project slip into the realm of the incomprehensible is too great.

>Everything packed into this tight range.

AS someone that grew up with metric that feels fairly natural and not tight at all?

>Inches/feet being base 12 divides better into thirds and fourths, which is very useful in construction.

I used ruler tapes with both metric and imperial on either side and i always wondered how one could use the inches since they're so big and didn't always have the same minute subdivisions. Also doing my math in decimals seemed easier than calculating with quarter or 1/8th inches or smaller.

>For science, sure, I'll use metric.

Surely it would feel more natural to use the same for everything and all measurements.

I want to know how much rainwater my IBC roughly holds. I take out my measuring tape real quick. I'm not even sure how I'd get started in imperial without some strong intuition build up over years?

Can/do people with aphantasia day-dream?

Is it common for people with aphantasia to not realize it until well into adulthood?

One of my good friends has it, didn't realize it until he was married (~40 years old) and his wife "figured it out." He doesn't care for fiction - especially written fiction, but movies/TV to a lesser extent - I always wondered if that's related. Aside from that, you'd never know - he's a good photographer and excels with mechanical stuff (rebuilding/modifying vintage motorcycles in particular).

Which is just German culture as much as food is Italian. If you want rules for everything I'm hard pressed to think of a more regulated country than Germany. And the populace, in general, might scoff at how long things take but absolutely want to understand what the process is... So yeah, you can't have it both ways
