And another point - how may of those school shootings ended before anyone the student called could do anything whatsoever to impact the situation? You are using 1 in 2500 based on counting all school shootings, but some 98% of those are over in seconds or at most a couple minutes.

From what I can tell, there's only been ~10 school shootings in history that involved "active shooter wandering the halls from class to class shooting large numbers of children." One every couple years in modern times. Far more often, either the shooter only had one target from the beginning, or only stays in one classroom, or is stopped right away. Extreme events like Sandy Hook, Parkland, and Columbine are burned into our collective memories, but only about half-a-dozen other incidents fit that mold in K-12 schools.
There are technical solutions to that problem though. I remember a Reddit replacement from a couple years ago called Aether. It made all moderation public, allowed clients to ignore a certain mod's actions (basically, personally removing them as a mod as far as their view is concerned), and allowed votes of no confidence for mods.

No idea if that model would actually work, as the app itself was one of those cool-on-paper-but-not-in-reality P2P types which made everything slow and likely made it rough attracting users.
We use a combination of RabbitMQ, Centrifugo, and Redis with a backend written in golang and our own job scheduling engine. Everything is deployed on AWS EKS.
While we thought about it a lot, no plans to open source it at the moment.
Splitting might help:

* Open source reddit-like clone designed for a single sub.

* Hosting company specialising in hosting this clone for a small fee.
So you can finish first and still be proud?
Homomorphic Encryption: Universality at a Cost
Exactly, there is no point in the system being "intelligent" and "emergent" for the sake of it, if the gameplay is buggy or boring.
Not a competitor to Reddit but something for smaller private communities. It's called Micro Chat - https://micro.mu

Previously on HN https://news.ycombinator.com/item?id=36135683

I think the public community thing is interesting but it's now been done do death and people's solution for smaller subreddits is federation or self hosting which I don't really agree with. I'm leaning towards even smaller "micro" communities that are entirely private. Talk to 20 people you know and get on with. Create separate groups/communities for things you care about. That's it. I don't want to have the discussion in public, I don't want upvoting/downvoting. I don't even want karma.

If you're looking for something entirely public like HN here's a thing I built last year https://home.m3o.com. no search though.
The argument isnt that we are unique but that we are far, far away.

It is considered fake because the perceived difficulty of space travel combined with the complete lack of direct evidence despite the ongoing search for it.
Homomorphic Encryption is a modern way of encryption that allows one to run algorithms on encrypted data without first decrypting it. We give an overview of the technology, discuss its many flavors and compare it with related privacy-enhancing technologies. Any feedback is welcome!
> Nobody sponsors btrfs development anymore

Doesn't SUSE still use btrfs as their default rootfs?

Looking at `git shortlog -sne --since="1 Jan, 2023" fs/btrfs/` it seems like folks at least at Suse, Oracle, and Western Digital have all made more than a dozen commits this year.
I think the easiest way to correct for it all is to publish the raw data, something that is trending heavily in the wrong direction.

Just publish the data, preferably for free.

> when 3D elements are part of the HTML standard.

They already are. CSS Transforms can already be configured to happen in a full, proper 3D space.

Every polygon of this demo is an HTML element, and yet it is fully and completely three-dimensional: https://keithclark.co.uk/labs/css-fps/

One would just need a browser in VisionOS that supports displaying these elements in actual 3D rather than projected onto the 2D surface of the webpage...
I would say that ORM's are an anti-pattern.
I would happily build the discord equivalent of reddit, no general space just requested access spaces. The problem with reddit from a mod perspective is that it is inversely open, anyone can see it, but very few opinions are allowed on most subreddits. I'd rather the inverse as it allows for more range of opinion and less "omg why do i have to see X when i open my laptop".
"You still owe the same amount of money but now everything is more expensive so technically the debt is lower" is a hell of a take.

Real wages went up briefly but then inflation caught up and brought real wages back down to pre-covid levels.

So I guess real wages are the same but went up nominally so the debt is lower but displaced with new debt.

In my experience the inflation numbers are way off. For instance, take food:

> The food-at-home (grocery store or supermarket food purchases) CPI increased 0.1 percent from March 2023 to April 2023 and was 7.1 percent higher than April 2022; [1]

Does anyone believe that 7% YoY number? It's not like I was buying ground beef for $4 a pound and now its $4.28 a pound. It's more like prices went up from $4 to $5.50 a pound

A few thoughts:

* allow for custom endpoint URLs, this way people can use open source LLMs with a fake openAI API backend like basaran[2] or llama-api-server[3]

* look into better embedding methods for info-retrieval like InstructorEmbeddings or Document Summary Index

* Don't use a single embedding per content item, use multiple to increase retrieval quality

Web apps and mixed reality: a vision the Glitch community has been leading
I've played around with using SQLite to store the scene graph for a game and using SQL to query/manipulate it. Very elegant and interesting ideas start to emerge, but performance quickly becomes a monster problem even if you run it in-memory. For simpler scenes, it definitely works though.

The reason I went down this path - I was thinking about streaming gaming and how we could potentially keep 1 representation of everything in memory and service hundreds or thousands of players with the same data set. Think tables like Scenes, Entities, Viewports, etc. Big picture, I felt like you might be able to pull off something at scale with a bunch of read replicas over a big boy SQL database.

Personally, in the past I never had a problem with paying a reasonable price for software if I end up “owning” it as the result of the payment, allowing me to use it in perpetuity. I especially liked some products that came with “lifetime updates”, eg FL Studio, where a purchase entitles you to future updates providing bug fixes and new features free of charge. I also like Jetbrains subscription model that allows me to use the current version forever even if I stop paying subscription.

But as the time went on - more and more restrictions were put on the purchase: can’t install on multiple computers in a household, the key cannot be reused when reinstalling, immediate absolution when continuous operation requires paid updates, and finally - full on subscriptions that don’t result in ownership. As the result of all this my desire to buy software ran out.
It should be always face to face.
I know it's not possible but getting a call to come next week to discuss the results makes a hell of a week to wait.
Also I wouldn’t be surprised investors are currently talking to Apollo about just this

Who is the target audience for this?
I'd like to see numbers on the distribution of wage increases.

Economists love to point to wage increases as if they're inevitable, but I suspect that is not most people's experience.

Anecdotally it feels like there is a small class of white collar workers who can reasonably expect guaranteed wage increases, and there's everyone else who's wages are basically flat for the majority of their working years.

If many people's wage increases are flat, it kind of ruins a lot of these economic arguments like, "Pay your house off as slowly as possible because inflation eats into the debt" or "Student loans are cheaper because inflation reduced the debt".

Inflation doesn't magically reduce anything, it just makes everything more expensive.

It's the wage increases that make things cheaper, and unlike inflation, the Fed doesn't guarantee that those are going to happen. Just the opposite in fact.
They have their own alternatives to CUDA & cuDNN called ROCm & MiOpen, as well as tools (HIP, HIPify) that let you write code that'll run on both NVIDIA/CUDA and AMD cards.

There are also AMD versions of PyTorch and TensorFlow.

The problem is that all of these efforts are not quite 100% there ... there are bugs and incompatibilities that seem to make most people abandon them. It's a shame since the hardware itself seems great.
This is going to be very confusing, since FF4J already means the Japanese version of Final Fantasy IV on the SNES.
This in a nutshell is why Visual Basic 6 eventually failed. It worked for your use case until it didn't. And of course a programmer could dive into COM and ActiveX to extend it, but avoiding that mess was why people chose VB6 to begin with.

The way this economic system works is that there are owners and laborers.

The way to make a lot of money is to be an owner.

However, open source mainly makes you a laborer. Support contracts are paying you for labor. It is similar to starting your own plumbing business. Yes, you can make a comfortable lifestyle, but you don’t really own anything apart from your labor, and if someone else comes in offering a better or more convenient deal, businesses will go with them.

I don't expect anything but anti-government propaganda from Reason.
I don't think anyone seriously expects the price to stay at $3500 forever. If the first gen product is successful enough to warrant a gen 2, I suspect by Gen 3 we'll see a more approachable price point.

The biggest hint for this is the name: "Vision 'Pro'". Why call something "Pro" that doesn't build on another product to enhance it with other features? The pro moniker for Apple has always been a sign of increased functionality for power users.

Mark my words; we will see a mass-market consumer focused version of this product within 5 years if gen 1 is a success.
I'd be surprised. Making (a few billion) API calls to someone else's database is much different than hosting and storing all that info (not to mention managing all the mods etc).
What a beautiful classic.
This is pretty exciting from the perspective of any kind of navigation. If this gets into a phone, we will be able to navigate on a digital map with no signal at all.

Hi there! We actually already have a built-in Nexmark source. It's pretty useful for developing new capabilities, and available as a source out of the box.

How do you feel about Bubble and how it compares? One thing that put me off Bubble was reports of it not scaling very well past a certain point (slow) - unsure why. Is this something you have heard/considered? I see debug mode, but if performance issues were to occur, could one x-ray the generated code or PSQL DB to rectify?

One bonus question, what can't it do right now that a Django or Rails API can? :)

I’m confused. Are we judging a product category based on how it’s promoted, or how it’s used?

I don’t think my opinion of smartphones would be any different if early promotions had shown the downsides, or bigger upsides, or bizarre and unrealistic scenarios. Am I wrong to be anchored on how they’re actually used, which literally nobody foresaw?
Fastback Photo Gallery
I made Fastback Photo Gallery for my family and wanted to share.

We have 200,000+ family photos (including scans of parent's and grandparent's photos and slides) and needed a good way to easily enjoy them.

Fastback sorts all the photos it finds by date and lets you scroll through them. A couple of key features:

* "Rewind" button to show media taken on today's date in previous years
* Date picker to jump to a specific date
* Map which can either show where photos were taken or be used as a filter itself so that only photos in the map area are visible.
* Filter by tags - if you have been tagging photos with faces or other data, you can filter by the tags

It's old school PHP and JavaScript. It uses ffmpeg to make streamable versions of the videos and either vipsthumbnail, ImageMagick or GD to make image thumbnails.

I would love feedback. Documentation issues, installation problems, suggestions, feature requests, etc.
If only they would also add support for writing on NTFS drives they would probably kill all the competition - who needs a Windows PC when you can have a Mac which can do everything you needed Windows for?
Of course it's safe for minors. My son is a minor and he's seen me smoking a cigar on multiple occasions. As far as I can tell, nothing about his safety has been compromised.

Respectfully, I think you've lost the plot here. The problem isn't labeling. The problem is overreaching in the first place. And the problem is an inconsistent application of that labeling.
This article is misleading. After a quick glance at the paper, I don't think the increased student debt was from them getting more loans, it was because they didn't have to pay their loans. So obviously that's going to go up compared to those who are paying their loans.

And to me the data on other types of debt reads that they were in fact doing better then those with payments. It shows those without student loan payments were more likely to be able to afford a house or a car.
That article didn't really clarify on the actual D3D to Metal conversion, so the specifics are still unknown.

From what I see, though, it doesn't look like Apple's solution is novel, and I doubt it would be considering this is a throwaway testing framework.
Show HN: Direct AI: Image classification without training data
I'm posting the following on behalf of my son Isaac. His incubator is Neo rather than YCombinator and he hasn't cultivated enough HN karma to post an announcement of his new company, so I'm doing it! He and his partner Ben have demos showing the use of their technology to classify images using only a word (or single example image) to tell the classifier what the you want to draw a box around in a live stream. No training or training data needed.

-------------------------------------------------------------------------------------

Hi HN!

For the past year we’ve been working to get rid of the last barrier to entry for building custom computer vision algorithms: training data. Today, we’re showing the world our progress!

Three years ago I joined an autonomous robotics company as an ML engineer. I was shocked to discover that at most companies the hardest part of ML isn’t designing neural networks; turns out most people just use the open source model that scores the highest on relevant benchmarks. The hardest part was gathering enough data to train that network to work for our use case!

I’m really passionate about the math of ML, so I looked into using the knowledge stored in foundation models to directly construct a model with the behavior I had in mind instead of gathering data and training one from scratch. CLIP (the model powering Stable Diffusion and DALL-E) has a lot of knowledge about the world and so people sometimes use it to build zero shot image classifiers with just text.

But zero shot methods don’t give you much control over the classifier, so they didn’t solve my use case. I took a shot at building a method that could take a list of positive and negative examples and use CLIP to build a classifier that satisfied those constraints, and DirectAI was born!

Looking forward to hearing your thoughts/feedback and growing with community :) thank you!

Isaac
Things in economy are counter-intuitive:

> By the end of 2021, borrowers who saw their student loan payments paused increased their credit card, mortgage, and car-loan debt by $1,800 on average and even took on an additional $1,500 in student loan debt compared to those whose loan payments were not paused by the moratorium.

It’s pretty cut and dry that they are worse off. We can argue about the whys, but people asking for a pause should not have been taken even more student debts.
2. I hate the name data lake but I’ve always used them as part of a pipeline. It’s useful to keep the raw data around when you need to recover / replay the pipeline.
It's a lot harder than it sounds. Moderation is hard, and these days I don't think it's free either, unless you have a very, very niche community with people who are passionate. This wasn't a problem back in phpBB days. You could have a forum with 100k users, and 500 people on at any given time, and moderation was extremely easy because people wanted to do it - it made the community better.

Reddit also has many users who are suffering from the familiarity syndrome. They don't care some API price is going up, they just want an endless feed of content and gazillion comments to mindlessly gaze through. This part of Reddit's audience is pretty much impossible to convert.

This is pathetic, but their U/UP line of monitors is really good. In fact I'm using them for the last 10 years or so. Back in the day, Dell was one of very few manufacturers who offered monitors with 16:10 screens, which are are far better at 24" size than 16:9. (The difference is not that noticeable with 27"+ screens and bigger)
Assume you meant competing rather than computing? Either could work!
That's a different issue.

If we assume honest dealing, when you see a $1000 display going for $500, you would think you get a high-end product at a mid-range price. You may then inquire why it's on sale - is it used, is it older generation, does the shop need shelf space? Who knows.

What should not be happening is that a product that has never sold for $1000 is presented as being worth $1000.

If you want free market to work, then deceit needs to be punished really harshly.
