Really, all the performance intensive parts are in various c++ aggregator and recommendation type services. But the webserver is Django, yes.

Thanks for your comment. I'm really interested in this topic. How do you know the web server is Django? I searched but couldn't find this. Why would they use Django? I did some small projects in it but I assumed it wasn't very fast and wouldn't be suitable for a big app like this. I would like to know the pros and cons.

They deemed getting to the market fast was more important than hardware costs. If their architecture is good, then they were probably really quick and flexible using Python to glue their architecture together which would have been the development bottle neck to getting the service up and running. All the components of the service can be done by separate teams in whatever language they deem most effective.

Most of Facebook is built on PHP. I’m surprised they didn’t choose Laravel.

It seems like you can generate links, but they don't do anything for people who don't have the app (except direct you to install the app). I haven't fiddled with it to see if they've implemented something to make the content visible to search engines. (Which presumably would mean I could see it too with some effort.) But I haven't seen such a thing yet. Edit: Someone kindly pointed out that you can see the content in…

At least there are links. That’s a good sign. TikTok survived on mostly that model, though it’s still important to make the content visible without installing an app.

Check my edit: It turns out this does work for deep links to threads and user profiles (the homepage is still entirely useless) as long as you don't have the app installed. Definitely much better than I thought.

> Threads is a mobile-only app, like Instagram Instagram can be used in a desktop browser just fine.

Let's imagine that I don't have an Instagram account because I don't. (I never really understood it because it just felt like a slightly differently flavored Facebook and I already had a Facebook account.) Up until this weekend, I could simply view a Twitter post regardless of whether I had an account. And while I've never been much of a Twitter user, I did find that useful as a lot of local news and weather type stu…

You could view a tweet if linked to it, but it would limit your ability to view a feed or navigate elsewhere. Which is similar to instagram, but insta is more aggressive with stopping you, whereas twitter gave a slightly larger grace period.

Twitter removed that behavior under Elon, then developed something even more restrictive. Great.

Neither are good, and unfortunate that tumblr has recently ish copied this (for default css at least). Real shithead behavior.

Unfortunately, Facebook looks the best out of all of them. If a restaurant posts their specials on Facebook, I can see them. Basically not true for other social sites.

Laravel wasn't created until 2010/11~

Laravel is not a requirement to use PHP effectively.

A fair point that it's stupid to implement a mostly plain text publishing site that doesn't support linking to any of the text published there. Edit: Someone kindly pointed out that you can see the content in the browser without an account from following a direct link. (You just can't have the app installed or it will open that and drop you on the login page.) This makes me a lot happier with the product!

You can’t link to threads? By design? I was seriously considering trying it out, but if there’s no search engine visibility, there’s no point. Most of the searches for my real name pull up tweets. Hopefully it’s just a missing feature that will be added later. Even TikToks are linkable, and those have very little google visibility.

I think Facebook/Instagram pioneered login walls for public post content.

A fair point about what? Threads is out for less than a day, I have 8 followers there so far. I originally posted this information on Mastodon, actually: https://mastodon.social/@ambv/110665808046065754 However, I have a much larger following on Twitter, so it was the tweet that got picked up by someone here on HN. We'll see how this looks like in twelve months.

Linking to it works better than linking to Twitter, in fact, as of this week (Twitter no longer shows replies unless you're logged in...)

Ironic that a post about Threads backend is hosted on twitter.

If you want real irony here, it's this: powering an app called Threads with Python that's got a global interpreter lock which makes threading hard. Get it? Threads, threading...? OK, I'll see myself out.

Meta does have their own higher-performance JIT-compiled implementation of Python, but I don't know if it still uses a global interpreter lock.

Could we get the mastodon link as the main link, please? Can actually view that one.

Is the Twitter link really not working for you at the moment? I can open it without having an account.

You can't see replies on Twitter links anymore, though that doesn't really matter in this particular case.

Of course, who knows what it'll be doing tomorrow. I'd definitely think it's probably time for HN to prefer Mastodon (or Threads, I suppose) links, where a post is available on multiple microblogging things; Twitter has had any one of about five behaviours for non-logged-in linked tweets (work properly, work but without replies, spin forever, redirect to login, generic error page) over the last week, depending on when you try.
