I indeed really liked Ruby because of it's expresiveness, it being totally OO, the lovely readable and writeable syntax.

But yeah, that was 20 years ago. These days I find Kotlin to be the perfect fit for my projects, because of the static typing and its ergonomic syntax. I just don't feel confident about Ruby projects when they start growing. But, I still love the language, although mostly for small things.

I like the sound of it, especially the compact single-file executable with minimal dependency. Forgive me for my ignorance, I may not fit the target user profile - I'm not familiar with KVM, and have only occasionally used QEMU. I read briefly about Cloud Init when setting up Multipass for creating new Ubuntu VMs.

What is KVM? - https://www.redhat.com/en/topics/virtualization/what-is-KVM

Can this tool `flint` replace some uses of Docker? I'm curious if I can use it for local development purpose, or for running stuff in production like isolating applications.

  flint launch [image-name]

  Launch a new VM with smart defaults. Supports launching from images or templates.

Is there a registry of images, like OS versions? Or maybe it's more decentralized than that. It also sounds related to OCI (Open Container Initiative) format that Podman supports, and qcow2 images for QEMU.

Could you give a brief summary of what this tool enables, for a potential user who doesn't know much about KVM?

KVM is just your Linux Kernel Virtual Machine. So you can manage VM's on Linux. It is not related to Docker.

I recently opened Pinterest after a year or so, and did look for some nice architecture / houses, and all results had the tag 'AI enhanced'. No I don't want AI houses, I want to see real architecture! Even though the tags are there, you can't filter on 'No AI'. So I stopped using it again.

So yeah, this is only really relevant for collecting logs from clickhouse. Not for logs from anything else. Good for them, and I really love Clickhouse, but not really relevant.

I work for a company that offers nutrition tracking on an app in the App Store.

We are not shipping camera functionality yet. But our concept is to not necessarily guarantee the accuracy of portions but to make lookup easier.

We also spent the time to get the AI integrated with a verified database. This made our results far more accurate.

We tended to find that without the lookup the calories and macros would be generally correct. The math was usually within a margin of error of 5%. This was acceptable except that… there was no micronutrient values and you couldn’t really adjust the portions at all. The system just dumps the macros and while you can halve something… the user experience isn’t great.

Ultimately, if you want precision: manual entry is the only way to go. I feel like out approach will end up being very great once we work out the kinks. Our search isn’t spectacular and as a team we are learning a lot of about prompt engineering and how to make best use of the AI.

Yes, I would think that would work better indeed. As a augmentation or help tool. I would love to be able to say to MyFitnessPal that 'I ate this and that food, same as usual, and oh yeah drank this.' Just as a easier input interface. I wouldn't trust a pure AI solution without some proper database behind it.

I use ChatGPT (4o model) to track my daily macros, specifically calories, protein, fat, and carbs. I have a prompt containing my macro targets and a list of the foods I typically eat or have at home. Throughout the day, I report my meals, for example five large eggs, two slices of sprouted wheat toast, and a cup of spinach with a pat of butter. It calculates the macros for each meal and keeps a running macros total so I can see how I’m tracking. It’s so easy—I don’t even type, I use (the overall excellent) ChatGPT’s TTS function in the iOS app.

If I eat something unexpected, I have it recalculate what I need for the rest of the day. If I were planning on 8 ounces of chicken for dinner but had an unplanned snack, it might tell me that 6 ounces will suffice now, and I now have room for more fat, so I could add some cheese. I find it quite accurate in this.

Where it loses accuracy is over time. Even when focused on just a single day, the cumulative totals can be wrong when the context window gets too large. I catch this by mentally adding up the numbers it spits out. If the numbers seem off, I open a new chat. Also, it’s not reliable for looking back over multiple days or trying to track long-term patterns.

When I take a photo of a meal (like when eating out), it performs very well. I ask it to list the contents of the plate, then I correct any assumptions. Once corrected, the resulting macros are usually within 5% accuracy. I also tell it the quality of the ingredients and restaurant overall, which can help a bit.

Did you verify it sometimes how accurate it is? I would be wary of it to be honest.

Ah yes, and every small Android dev is banned from Play and Admob for tiny unknown reasons, with no recourse or way to communicate with Google. But Meta here probably won't get any problems at all. They should be temporarily banned!

What's the Android app? If it's for a general audience, this is a good opportunity to plug it :)

Haha, well it's that you asked. Mini Piano Lite, a piano app. Building it for 15 years already. https://play.google.com/store/apps/details?id=umito.android....

Very well rounded and grounded article. Like it very much!

Indeed as someone else in the comments said, the personal touch is the best asset you have as indie. So talk with your customers.

I run a Android app, next to my day job, and I pride myself on always putting the customer first, and actually fixing their pain points or implementing their suggestions. Empathy is so important, and something a big company will struggle with.

I'll checkout the recommended books!

I really like Clickhouse. Discovered it recently, and man, it's such a breath of fresh air compared to suboptimal solutions I used for analytics. It's so fast and the CLI is also a joy to work with.
