I've recently been prototyping a mobile application to track your food nutrition. The key feature lies in auto-detecting the food based on a given image, and breaking it down into it's ingredients and then into it's macros. Existing apps such as MyFitnessPal and HealthifyMe fall into two ends of the spectrum where you either need to add ingredients one by one, or your food is logged with a standard macro count where…

Not sure if you are already familiar but I use Cal AI and think it does a pretty decent job. How granular do you track the macros? hard to figure out from a picture if I used some cheese or how much oil.

CalAI is a scam. It's highly inaccurate, there's no way to determine calories from a picture for a multitude of reasons

Well done, LinkedIn is a cesspool. Ironically the only thing I am using right now is Twitter, since a lot of interesting people are still on there. There's a lot of negative but balance as well. For every MAGA or ESR's comments, I balance it out with Miguel de Icaza's views on Gaza, etc.

You should be able to use Twitter without justifying yourself

"Should" being the operative word. It was easier a few years ago

I am building Buckaroo [1], the data table UI in Jupyter that I have always wanted. I know how to use df.head(), df.describe(), sort, and run histograms on columns. I just got tired of typing 5 bits of code to minimally inspect each dataframe every time I looked at it.

So I built buckaroo, it combines a high performance scrollable table (built on top of ag-grid), with summary stats, and histograms. All of this is customizable and extensible. I recently built a dataframe compare tool [2] on top of buckaroo that uses coloring to show differences between dataframes intuitively.

Get in touch if you want to talk tables, data science tooling, or exploratory data analysis.

this idea has been rinsed and repeated many times already. unless you're going to include manual input in addition to the image recognition, it will be highly inaccurate

I've been working on an app that will use ai to decorate my Anki cards with audio/example sentences/images. The more I get into it though, the more I think I may just end up writing my own flashcard app. I feel like most of the project has been spent wrestling with AnkiConnect, while the fun stuff has been fairly simple.

I've been thinking about the same some time ago. But after a while I got to conclusion that Anki is pretty well designed after all. Although for what I remember Anki Connect is in form of unofficial extension. And it would seem that there is a place for an official more stable API. Anyway I never got beyond thinking about it. Just to let you know you are not alone, and you can ping me if you ever decide to do something about it.

I'm building a new tool for end-to-end data validation and reconciliation in ELT pipelines, especially for teams replicating data from relational databases (Postgres, MySQL, SQL Server, Oracle) to data warehouses or data lakes. Most existing solutions only validate at the destination (dbt tests, Great Expectations), rely on aggregate comparisons (row counts, checksums), or generate too much noise (alert fatigue from…

This sounds interesting. Is this meant to run in pipelines or be used interactively?

Are you building something open source? Link to the repo?

Making a CAN-to-BLE bridge for cheap race car telemetry. It’s using an ESP32C to store MegaSquirt ECU data in BLE characteristics, and a cheap android phone using Chrome + WebBluetooth to buffer and upload data to a server for pit analysis in near real time. Also using the phone for heading, GPS and accelerometer data.

With English not being my native tongue, it gets difficult to speak some words at times and I have to reshoot each takes several times. But it's worth the effort and it's different to what I do in my main channel!

Well, I know that I was just saying that HN is not the place to look for gamers, but I am still working on a video game.

Danger World (https://linktr.ee/playdangerworld) is well underway and should be coming out later this year! Danger World is a 2D narrative adventure written using Flutter's open source game engine, Flame. I am the solo developer. I've been working with a very talented art team to do the art and animations in Spine. The composer has just finished the soundtrack!

Danger World is running on iOS, Android, MacOS and Windows. Last week, we got Danger World compiling on my Steamdeck for SteamOS instead of having to use the Windows .exe + Proton. I'll be getting the Linux depot setup in Steam soon.

In the spirit of doing things that won't scale to get some interest bootstrapped, I've been doing a sticker giveaway. I have a bunch of stickers featuring the cast of the game and the Danger World logo and I have been mailing them out to anyone who wants them. I've sent out 40 envelopes or so with about 10 stickers in them each.

So far, in experimenting with the various social media platforms, Bsky seems to be where my potential users are. I posted a boxart concept that I was using for IndieDB and got 100 followers from that single post of who all appear to be real actual users. Certain engagement metrics like impressions are non-existent in Bsky, but in exchange for real actual engagement from people who seem interested in my game's art, who cares?

X feels extremely P2W, except you buy their checkmark and they still don't show your content to anyone. I'm still experimenting heavily in social media land. Meta and Tiktok seem to show more promise, but since I've been scoping out and planning a visual novel mode I have also been considering taking Reddit up on their free ad credit.

I'd love to talk with anyone more experienced in marketing games like mine.

I live next to a school, so there's a low speed limit (30 km/h). Still, people drive like race drivers and the city hasn't ever responded to the residents' hopes of introducing a speed camera. I wanted to have some data on how many people speed, the max speed recorded, that sort of thing. Things the city should be doing after many complaints of dangerous driving and people being almost killed on zebra crossings. I ha…

Is that legal in your country? In mine (Netherlands) there are way too many people with doorbell camera aimed right at the street even though it's illegal to record a public space like that. Most folks are ignorant about it though, or think that surely the internet-connected gadget sold by some anonymous corporation won't be abused....

It's not legal where I live (Belgium), it can be legal if you have a driveway and only film your driveway, and if you declare that camera in some database. But since I don't have a driveway, it films the street, I am aware that this is not legal.

It's my personal decision and if I ever get fined for it, I will gladly pay the fine... with the money that my doorbell camera has already saved me. It helped me catch hit&runners that bumped into my parked car twice already, and the camera is now almost two years old.

It's not connected to the cloud, saves data locally, and only stores a couple of days of video. It's not very ethical to unknowingly film public spaces, I know. My lame excuse is that I personally think that catching people that damage my property with a camera is a lesser crime than damaging someone's property and running away. The sad truth is that living in a place where parents drop off and pick up their kids twice a day do not give two shits about others. Hit and runs happen every day here.
