I have been building in AI for the past year, and one of the most frequent questions I get from peers and juniors is, "How do I get started?"
To answer that, I began documenting what I’ve learned along the way. From Prompt Engineering and Retrieval-Augmented Generation (RAG) to fine-tuning large language models, deploying AI systems, and working on real-world projects, I’ve organized it all into one comprehensive roadmap.

I truly believe in learning by applying, so the repository is structured in a way that allows you to run any notebook easily. You can dive straight into hands-on projects, experiment with code, and see concepts in action as you learn.

This resource is entirely open source and designed to help anyone interested in AI get started and progress through structured, practical learning. Whether you're a beginner or looking to advance your skills, you’ll find tutorials, insights, and real-world applications to guide you.

Yeah no, it isn't safe-by-default. I caught a frontend team shipping keys in the frontend code. Cause? Typo and using default templates which built-on-deploy.

It was a point against the "app for the rich" + "to point out nearby Michelin rated and other high end restaurants and amenities." in the context of suggestions for app features.

There are no assets for digital currencies so the words you're using to describe it are ontologically nonsensical. It's numbers, binary sequences, in databases. The only thing that makes it all work is your belief and faith that the numbers mean something other than the electricity and infrastructure necessary to maintain the databases. The only real assets in the entire scheme are the computers and power plants with the spinning dynamos necessary for maintaining the illusion of "value".

This is why the masses are always dazed and confused. Your water and food are full of poisons but the numbers in databases are what get the most airtime. Bitcoin is the purest distillation of fiat currencies because there is no longer any actual physical manifestation of it anywhere other than whatever paper key you keep on you as a reminder that there is a database with some numbers which you and those like you collectively believe to be "valuable".

I would discuss with HR. Their job to understand and comply with the laws.
Yup, just do it! Whenever I write a new piece of docs I try to fit it into one of four categories. Whenever I find docs written by someone else and they're all over the place, I message them and say "Hey this would be much more useful as a how-to" and link to this site.
I don't agree with it because while I think that it's theoretically correct, the words are too close together. To me "tutorial", "how to guide" and "explanation" are all practically synonyms. I know that when you think deeply about it, there are legitimate reasons for each category but it's just too close semantically that my brain can't see the difference. If I want to know how something works and I see "tutorial" and "how to guide" I have no idea what to click and I just click on the first thing.

If commodities are at record highs, then the dollar is at record lows. Just because other currencies are inflating more, doesn’t mean the USD is getting stronger.
I spent ten years in a plastics factory before switching to programming. I used to grab a roll of paper to sit on even though it made me look lazy compared to everyone else there, because standing is hard. So I feel that finding any new way to remind people every few years that we are sitting because others are standing is virtuous.

We also spend too much time on sympathy for people at the very bottom of the income tables, often there out of laziness or crime, compared to people who have twice the stress by being both low income and working hard for a living. They deserve more visibility.
I think market cap is a much better value to discuss than price.

With $2T it is in the range of the largest companies in the world. Google is $2.1T, Apple is $3.6T.

It is still roughly 10 times smaller than gold, which sits at $18T.

I find it hard to imagine that Bitcoin might not surpass gold. The gold market cap shows that there is a demand for $18T of storing value in an asset with low inflation. And Bitcoin is better than gold, as its inflation is going to zero. And it is easier to store, transfer and verify.

I would love to hear some opinions on why Bitcoin might not surpass gold in value.

Unfortunately, all the internet forums about Bitcoin that I have found are very low quality. I wish there was a Bitcoin forum as good as Hacker News. Or a general investment forum as good as Hacker News.

>All of these would have been [less than half the price] just 2 years ago.

Here in Toronto, I can't think of a single food item that has done anything nearly that absurd price-wise. Eggs and dry pasta are currently at or approaching double what they were pre-pandemic (i.e. ~5 years) and that's the biggest increase I can think of over that time period. (Milk is up a bit over 50% when there isn't a sale; sugar perhaps 60%; ketchup perhaps 30%.) A lot of these increases noticeably started in 2021.

On the other hand, there are definitely things I can still get (at least sometimes) at the same prices I remember from years ago. And I've been improving my budgeting habits across this period of time, so my actual spend has been remarkably stable.

What you describe in LA is unfathomable. I'm accustomed to being taken aback by how cheap meat apparently is (was) in the US. Has the situation reversed?

Played TTD for hundreds of hours as a kid. The soundtrack and ambient sound effects are still so clear in my head - distant sounds of industry and vans and busses and trains just doing their thing. And then occasional updates popping up. It had a really nice flow to it. Very addictive. I'm fairly sure I spent at least one 'sick day' off school playing TTD instead.

I've tried OpenTTD and the touch versions but they didn't grab me the same way. Maybe just a different stage in life? I just try OpenTTD again though... Just to scratch that itch.
Yep, point being it should be part of the title, as that's the degree to which it impacts results, and the title is what has the biggest impact.
> Without that system, the 75-year-old author would earn drastically less than the 20-year-old, despite creating the same value.

Less perhaps, but drastically less? You'd need to justify that. Even big hits generally make most of their money in their first few years.

And creating the same value is also a claim you'd need to justify. Maybe society legitimately prefers works from younger authors; maybe a work from a live author really is more valuable than a dead one. Maybe there are unique things that a living author can do with an in-copyright work they wrote in the past, that increase the value of that work, and we want to incentivise those things.

The approach works better with dedicated technical writers. It makes sense to have distinct user-focused goals for documents before they’re written, and then just dig into the necessary parts of the software enough to make that happen as needed. When it’s developers doing the docs, they’re approaching it from the other end. They’ve got a chunk of code they need to cover, and reasoning about user needs is pretty difficult from that vantage point. Picking an approach vector when you don’t know the airport.

Snail mail has never claimed that a history of all messages, with that history having a current state, exists. If you send a paper letter, you don't have it yourself anymore. You might keep a copy, but that's a _copy_, not the letter you sent.

Messenger apps claim that such a history exists by showing you, well, that history. In the same way, messengers claim that a message order exists, by showing you the messages in that order. If something exists, then it is independent of the viewer. So the assumption that the message order is the same for all viewers is founded in how two people look at physical objects.

So I have high blood pressure (middle age it seems sucks), and have been under a cardiologist for 18 months. The first thing he said was “this wearable is good”, so of course I bought it and it’s been on my wrist consistently.

The company is legit but has made considerable effort not to allow the data out of their eco-system (exports only to pdf, no ability to send to Apple Health etc).

So I notice that I send a quarters worth of pdfs to the doctor, whose secretary prints them out and he flips through them with a strange expression trying to work out what’s going on.

I have taken a few frustrating lunchtimes to parse out the pdfs and have gotten to the point I can get the data and graph it - but what to usefully do with it is interesting

I think you’re misreading the price on those chicken breasts. At the Whole Foods at 3rd and Fairfax, grilled chicken breast is $16.99/lb [1]—which I believe is the price for any food from the hot bar. A typical chicken breast is 1/3lb to 1/2lb before cooking, so you’re really looking at roughly $5.50 per cooked chicken breast.

Uncooked organic chicken breast is $10/lb [2] at the same store. Non-organic is $7/lb [3]. Since Mary’s air-cools their chicken instead of dunking it in frozen water, you’re not paying for an ounce of ice with each pound of chicken.

> How far back should you be able to amend history? What if a malicious client adds messages to a conversation that happened in the past? Imagine for example I'm at work and notice a critical mistake that I missed, and so I retroactively add messages to the old conversation to make it look like I'm not liable, should that be permitted by the protocol?

I believe that's impossible? At least if you design it correctly.

For ordering/interleaving purposes, what matters isn't the time you claim to send the message, it's the time the message is received by the server. If you want, you can display the claimed send timestamp beside the message (and prominently highlight it if it is e.g. out of order, or with a long delay, etc.), but that is irrelevant to the ordering.

The point here is that there should be a single consistent order on the server, and that's what all clients ought be displaying. Any messages not yet acknowledged by the server should be displayed differently so that users are aware they haven't been seen yet, and any messages that arrive before those are sent would obviously get inserted above those.
I'm the author of the spec issue this blog post is based on: https://github.com/matrix-org/matrix-spec/issues/852

In my implementation for the Conduit Matrix server, the /sync order is used for everything. The timeline is just one list that grows on one end for incoming events and on the other end for backfilled events.

I think it's important that the message order does not change, because that's very difficult to communicate to the user.

Or is the point that nothing is comparable unless I am sitting still each time?
