I'm really interested to know when we will be able to prove that we have the fastest algorithm for some matrix multiplication problem. Is there a theoretical lower bound? (well in this case, for 5x5, there's gonna be an actual lower bound. but for asymptotic cases..?) Is figuring out the theoretical lower bound some kind of undecidable/NP problem? what do we know about it?

People often say monopoly when talking about general anti-competitive behavior/abusing market position. If you want to nitpick on that point, that's up to you I guess, but you must know that changing how people talk about this is completely hopeless at this point, right?

How do you back them up locally?
I’m so confused by this argument. Why do people think that gait and biometrics data is so valuable for running ads? Trust me, there are millions more features that are more closely predictive that top ML models are just leaving on the table before you get to “what’s your eye saccade rate”. Also, while Meta’s track record is horrendous, they actually have done an okay job at locking down how data is used internally. New use cases are very heavily scrutinized, it’s the old grandfathered ones you should focus on, not new ones from VR.

Also, Quest isn’t cheap because it will eventually collect ads data, it’s cheap because social VR, the main Meta argument, requires adoption. It’s a multibillion dollar bet that enough people will have it that it’ll be less friction.

> I don't feel like it's worth giving up control over your user's authentication to an intermediary in return for saving a week of work. Maybe the case could be made for day-1 of a startup, but certainly not year-1, it's just too critical a component.

Are you not outsourcing to an intermediary with Apple/FB/Google?

Authentication is critical. Completely agree. It is also not a differentiator for your application unless done poorly. Using a 3P such as Apple/FB/Google leverages the account protection investment that those providers are making. Using Hellō gives the same protection, while preserving the user's privacy (provider does not know which app the user is logging into) -- and giving them choice and account recovery.

As noted, if you have already made the investment, Hellō does not provide the same value today.

> I'd also challenge this taking a week. Apple/FB/Google sign-on is pretty straightforward, and I've found the cost is mostly in setting up an open-source auth library in my webapps rather than enabling a given service provider.

I'm sharing my experience. Apple requires a D&B number to register your app. Many require you to jump through their process for proving control of a domain. Microsoft requires you register as a partner if you don't want the scary unverified label. FB disabled Hellō for not having the correct link to the app, then disabled for not having a required term in our T&S.

Others may not have the same challenges as I did -- but it was non-trivial amount of time to manage the app registrations.

FWIW I don't use libraries for the OIDC flows -- I find it makes it more complicated than it needs to be. I do use libraries for any JWT work of course.
Show HN: The missing pieces of Slack Workflow Builder, open-source
Hello HN, I'm Kevin, and excited to launch my very first open-source project!

For a long time I was frustrated that Slack Workflow Builder[0] didn't have outgoing webhooks, and that they boxed you into so few options for triggers despite the rich Slack event ecosystem. So I waited for Slack to build it in 2020....

and 2021...

and 2022...

and finally last month I got fed up and built out the core of an open-source, self-hostable bot[1] to complement Workflow Builder with any missing functionality. Called it Workflow Buddy cuz they go hand-in-hand .

It lets you use ANY Slack event as a trigger for your Workflows, and adds a bunch of new `Steps from Apps` to your Workflow Builder, the most important of which is the Outgoing Webhook - finally a way to send events OUT from Workflows, not just inbound, and make them more useful for automation. It's set up for easy addition of new Steps as community members come up with new uses cases!

## Tech Stack

It's built using a Flask server + Slack Bolt Python + deployed on Fly.io. Trying to keep "perfect is enemy of good" in mind, so the simple storage for the config data is all done through a JSON file - works for now!

## How it works

For adding triggers to Workflows, the bot acts as a proxy - you create a Webhook-triggered Workflow in Builder, configure an event->webhook mapping, then when Buddy receives the event it forwards it through to your regular Workflow.

All the additional steps are fairly basic, the 'Outgoing Webhook' step is basically just fancy, user-friendly inputs getting passed to the popular requests package.

I am by no means a great developer, merely gluing together other people's amazing work!

## Fin

If you're interested in deploying your own Workflow Buddy/contributing, I can help with questions or hop on a call to get you set up - excited to see other's use cases![4]

Let me know what you think! Curious to see if others have run into the same frustrations with Slack Workflow Builder's high potential, but limited functionality.

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

Q: Isn't Slack going to eventually add these features to Workflow Builder?
Maybe, but until then, you have an option rather than waiting impatiently. Plus, since it is an extension of Workflow Builder, it won't stop working if Slack decides to add new functionality to the core tool.

A Model for the Probability of Nuclear War
I'm surprised at how much backlash there is to this.

I've had Signal since shortly after it renamed itself from TextSecure to Signal, and I never bothered using it as the default SMS/Messaging app, because back then it was a bad SMS app. It felt like it paled in comparison to what the default Android Messages app could do. I didn't want to get the false impression, either, that my chats were encrypted when they really weren't, just because they shows up in Signal.

So I kept the two separate. I assumed pretty much everyone else did the same. And yeah, there's the occasional oddity when someone texts me over SMS instead of using Signal when I know for a fact that they have both, but most of the people doing it are using iPhones, so I have to assume it's the same experience for them as well.
My most recent boss, who was DAMN good, got his shit done etc... taught me one very important life lesson.

Stop at the end of the day. Pick a time, or a number of hours you'll work... and stop.

Close the laptop for work use, and that's that.

Pick it up tomorrow. Have a boundary.

Yes, I really like my current company. But that small boundary of stopping my day's work every day. Not carrying my work like a cross... Makes it so when things swing to and fro at work, my head is much more level. Even if you are on a roll and in the flow... consider closing the laptop when you lose your current flow.

Then go do something else! Play a video game, knit a sweater, take a walk, fly a kite, hug someone you love...

That's your time. Use it and enjoy it!

If you feel guilty, remember... Rest is critical to performance. The sooner you realize this, the happier you will be at work, and outside of work.

got to be over for food delivery apps, who must have been hoping for drones to take on the role of last mile delivery, but it hasn't happened in time for labour laws to crack down.

Interesting to know what happens to food retail in general - restaurant / in person dining obviously devastated by Covid / Cost of Living Crisis / Increased Cost of Employment, so the 'ghost kitchen' emerged as restaurants just cooked the food and had gig platforms deliver to customers. Now these labour laws will increase the price of food delivery to be point where the market won't pay. We are just going have to cook more of our own food

I'm curious to what extent the effect is country-specific.
It's terrible. Every once in a while they decide to convince me that I really don't want to be sending an SMS but I want to use google's messenger of the month, that will inevitably be gone next month.
Thing is, now they've shown a willingness to make this change, so from here on out people will be worried about them trying it again at some point.

The only way they have a hope of putting this genie back in the bottle is to provide a loud, strong, clear mea culpa, stating that they were categorically wrong to propose dropping SMS support, plus a strong promise that they will continue supporting SMS for the life of the product. Maybe something along the lines of, "if we ever propose dropping SMS integration again, you can consider that a warrant-canary type of alert".
Yeah, that's roughly what I figured (IANAA). But it still seems hard to explain six flashes bright enough to appear like a supernova. I'd expect the flash of any kind of supernova to be brighter than the flash of a shockwave hitting a shell of gas. But I know nothing.

And anyway, for the shockwave from a supernova explosion to hit the shell of expanding gas from a previous explosion, that still seems to imply two supernova explosions from the same star. The only way I know that can happen is in a binary system.

'Sentient' brain cells in dish learn to play video game: study
Segways sold a total of ~140,000 units across nearly 20 years of production[0]. The original Quest sold more than twice that in the first 6 months of it's release[1], and Quest 2 sales have well exceeded 10 million units.

> The phone is absolutely better. Better battery, nicer looking screen, more solid feel, faster processor, better game performance, better software integration

Better than what, budget phones? Android phones worth half its price have comparable features nowadays. Apple has failed miserably in gaining customers from markets where its hegemony wasn't already established, including the world's largest smartphone markets (China & India). American localisation is absolutely the largest thing going for them.

> Surprisingly, data show that sugar consumption does not worsen symptoms of ADHD.

Surprisingly? Sugar consumption is known to help with symptoms of ADHD, as do other dopamine-inducing activities, which makes perfect sense to me. The problem with sugar is that it has a pretty high cost due to all its other effects on the body, that its dopamine hit wears off pretty fast and you quickly build up a tolerance, which is why it's good to look for other stimulants than sugar.
There used to be an app called Popcorn Time which had a Netflix-like UI but was actually serving the videos from torrents. It would attempt to download the torrent data sequentially so you could stream the show/movie after about 10 seconds of buffering.
yet the government is giving monetary aid because electricity prices have skyrocketed, since the price all over EU is pegged to the price of gas generated electricity.

> For some reason, some people are very reluctant to pay for tools, even though they use them every day in their job.

I used to pay Jetbrains annually, out of my own pocket. I continued paying fir a personal license even after my employer bought me another license. Jetbrains then made a stupid, greedy decision[1] (and walked or back within days), but I was done with them and canceled my subscription.

Since then, my experience/growth, languages tech stacks and codebases have connived to make Jetbrains superior discoverability moot (not using Java!), I found out other IDEs are good enough for me.

1. Some years back, they decided on an IDE-as-a-service path where they were going to brick your IDE the day your subscription lapsed. The fact that they thought this was acceptable and announced it means they cannot be trusted, IMO.

It amuses me that Westinghouse sold for $8 billion when Twitter is worth between $38 billion and $44 billion and when the original price quoted for AP1000 reactors at Vogtle was $7 billion a piece.

It begs the question of "What exactly does Westinghouse sell?" They don't pour the concrete (the local Mafia does that), they don't make the coolant pump (a factory in China makes that), and they certainly don't own the monster press that is used to forge the reactor vessel.

I'd imagine that they make money based on licensing patents and trade secrets to the vendors that make the thing, and if that's the case it seems likely that they don't make extra money when construction goes wrong and that $7 billion turns to $15 billion.

I think you could make a strong argument for the "sign" on the morality of pirating being negative.

But the "magnitude" is so low, I can't imagine caring when other people do it.
I’d caution against publishing the code directly to the public if we’re talking about a well known brand name like Ring, Wyze, Nest, etc. You may end up getting involved in a legal dispute if you do that so for your sake report it through their vulnerability disclosure process. If it’s a no-name brand camera, those are frequently published and corrected in future firmware updates so it’s more or less ok to publish those.

Don’t count on that vulnerability being around forever though, at some point someone else is liable to find the same issue and report it. Sucks that vendors won’t give us access to the underlying OS for the device we’ve purchased. A lot of the consumer grade cameras would instantly be more valuable to me if I had that kind of access without having to hack the device for it.
This kinda feels like there needs to be some self-reflection. From the article:

> For me, the whimsy trend all began with Flow Club. Their tagline is "Feel good getting work done" – that is so against modern hustle culture and American workplace vibes that it's almost jolting.

To me this sounds more like a coping mechanism as are all the other productivity err.. “enhancements” mentioned. If only we made work more jazz hands it’d be better rather than improving the material conditions it’s conducted under.

Similar to gamification it’s taking the wrong lessons.

He is mostly talking about computational linear algebra problems of a large scale type due to large matrices: the "computational intensity" comes from having really large matrices (kxk for k = 100's, 1 000's, 10 000's, 100 000's, 1 000 000's, ...).

In computer graphics, the situation is often different. Usually, you have small matrices (kxk for k=2,3,4); a huge number of vectors; and you want to apply your matrix to all of those vectors. Very often, these matrices have very well known forms and also known well behaved inverses. There isn't really a significant computational cost in computing the inverse (you'll very often write down its formula by hand), and conditioning is usually not an issue (consider a rotation matrix for example or undoing translations with homogeneous coordinates).

Think of the game theory and organizational evolution in such a flat hierarchy, especially when the flat section is a middle management level.

This flat hierarchy works at the low level. It already does almost everywhere on the border of "production workers" and "low management".

But in the middle management, the incentive is promotion and control. You start out with a flattened hierarchy, and say 20 managers vying for promotion, well, you probably won't get promoted. Then why try hard? Uhoh, now most of your managers will either:

1) leave

2) fight over / jockey over being the "senior level" of the 20 underlings

3) stop trying

4) embezzle

5) gradually conspire to "unflatten" and add more levels, gain control (solid line or dotted line) to the territory of your peers
