Ask HN: Best way to communicate in Q4 2024 internet?
There’s been a noticeable trend over the past few years towards the fragmentation of chat networks.

Every major company is pushing users toward its own proprietary chat service. As a result, people are often forced to create multiple accounts across different platforms to stay connected with friends, relatives, and colleagues who all use different services.

For technical people, what are the best approaches for connecting across different chat networks?

Here are some options I’ve been considering as a "main" protocol:

- IRC: While IRC still has a loyal user base, its popularity has steadily declined. It also lacks modern features like voice/video calling.

- XMPP: I don't know much about it. XMPP's community support seems less widespread compared to other alternatives.

- Matrix: Matrix offers a modern and feature-rich protocol, but it can feel heavy. Synapse, the most common home server implementation, on different occasions I've seen it to be quite slow (For example when joining a room).

My idea is to set up a server with bridges that puppet connections to various chat services, so I can manage all communication from a single place.

Is this plan feasible? Has anyone successfully implemented such setup?
But this gets to my question, essentially? Is "aging for the elderly" different than "aging for the middle aged?"

So, what does it mean to "beat aging in a medical sense?" If it is just definitionally to not have any of the bad effects of aging, then sure. Of course I would want that. What are the names for the good things that are generally along for the ride with aging?

Going back to my earlier quip, if you could turn off aging for babies/toddlers, how would that be a good thing?
How does one make money from owning s** tons of stock during a restructuring? Do you have any examples
OT, but I love your newsletter!

Didn’t notice your username until you wrote “French”
It's early days, so while there might be some overlap, I am sure there is a lot that we can do together to build complimentary products.

Based on the press release, its kinda hard to tell exactly how different/alike we will be, but Arch will always be "designed-first" for prompts and LLM application workloads without exposing all Envoy related features. And Envoy is "designed-first" for micro-services application workloads. So there will be some overlap but our design principles will deviate over time I feel. But we are very open to collaborating with the community here...
>Not sure why this necessitates AI hardware

New Siri and iOS notification summaries seem like it should be enough of a reason for apple to want to ship an iPad with ai hardware.
Google needs to be broken up. It's extremely concerning that a company that derives most of its revenue from internet ads, can use its control over the world’s most dominant browser to limit apps that are a risk to its bottom line as it pleases.
I have never, in 2+ years of using AI spent more time verifying the output lol.

It takes like 10 seconds.

You’re just using it to point you in a direction, not solve the entire problem.
That’s expensive as hell, but I see my company listed as one of their customers. Going to see about getting a seat lol
fewer dependencies than ipython perhaps, but still unacceptable for something that needs to be shipped as part of the language. also I feel that you are unduly pessimistic about its chances and that the PEP is right about this one - being written in python rather than C will get it a ton of contributions from the community if anything is found lacking. particularly since you won't necessarily need to know a ton about python internals to just contribute to the repl

FreeBSD/EC2 boot performance over time
That'd be because it's all CPU-based at the moment . So your 4080 is taking a vacation while your CPU hits the gym. That's obviously not ideal, but you'll have to trust me that it is due to long-term architectural planning reasons and not a blatant disregard for sensible development practices. Our node graph engine is really advanced—it's actually a scripting language built upon Rust and its type system—which will have some very sizable benefits once it's done being built. But right now, it means vital things like GPU compute have been blocked by a towering pile of other engineering work. But we've nearly completed those prerequisites and should be able to unlock GPU compute in the early parts of next year (this is also blocked on Firefox and Safari shipping WebGPU support, required to use compute shaders in the browser— and on us having the time to support Windows, Mac, and Linux builds via [Tauri](https://tauri.app/)).

In short, please be patient :) The app's architecture is designed with performance that'll make your CPU and GPU scream, but it's a big job building all of it. Especially for raster imagery, that's where a CPU-bottlenecked render pipeline is especially affected. But next year is the year we move on from vector graphics to raster once the GPU is utilized in the render pipeline.

Thanks for taking a look!
bizarre fixation on china huh
Cutting out sugar and useless carbs, and trying to replace those things with nuts and quality proteins - more nourishing and filling substitutes, can help a bit, I think. Mostly, try to stay away from refined sugar and products containing sugar or corn syrup. And for the love of God, lots more vegetables. Less dairy perhaps?

Eat lots of chili peppers[0]:

"The analysis included data from more than a half a million people in multiple countries. When compared with people who never or rarely ate chili pepper, those who ate it regularly had lower rates of death due to cardiovascular disease (by 26%), cancer (by 23%), or any cause (by 25%)."

A little bit of high-intensity workout each week?

I know people who are incapable of eating lunch or any meal without a large can/bottle of full-strengh coca cola or such, ever single day. Most of whom complain about not being able to lose weight.

The science is pretty clear. Breaking out of old habits is much more challenging.

EDIT: Typos: whole -> whom, mean -> meal
The current thinking is that Alzheimers and dementia are caused by the brain’s waste disposal system malfunctioning and results in an accumulation of proteins in the brain that damages a lot of important functions. This waste disposal only happens during sleep.

>All companies that try to hotswap batteries inside cars are miserable.

You misunderstood. The cars must be designed for this, which they are not. Battery swapping was very effective for early EVs over a hundred years ago.

>Real fast-chargers and very fast-charging (800V) cars actually exist.

Nothing can be faster than swapping a battery. It should be possible to swap one in 2 minutes tops, if cars were designed for that. Of course, you'd also need a reliable consumer protection scheme, unless nobody ever owns a battery. You'd need insurance for the battery in any case due to how expensive they are and how easy they are to destroy.
Google built a profit model on the original organic internet while facilitating that web's replacement with today's wonderful SEOable 'content'.
I love the stats. I wonder what kind of business actually needs something like 1,800lb of cooked bacon per hour.
Well, yes, probably

I code on my free time because I enjoy doing so. I find C to be fun (even if I suck at it)

Have you looked to see whether there is a local archaeology or social history society in your area that you could join? They will have individuals involved who are already used to dealing with property owners to arrange research projects, and you might be able to accompany them on the trips they organize. For reference, the archaeological society in my region serves around 400 square miles and typically organizes a low two-digit number of digs every year. There are also some other societies in the same region who focus on preserving and documenting recent history where excavation isn't required.

Another idea: if you don't already have any formal education in history, you could study for some qualifications in the subject. It would probably do much to reassure landowners that you are not going to harm the sites in any way (although I struggle to think of a way you could do so with a UAV!) In any case, good luck; I'd love to see the models!
I feel like Polyglot programming in single app sounds like a nightmare but as non dev, meh, whatever.
Thanks for keeping things tidy! I'm more used to the Reddit side of the internet so I appreciate the help keeping to the norms here on HN.
It's the bit of life where you can dress yourself and control your bowels that most people would like to extend. I think nobody gets into longevity research hoping they'll be able to dodder around a nursing home with a walker for 25 years instead of 15.
They don’t have a reputation for releasing hardware without software to back it either. One way or another, an unprecedented process failure has occurred.

It's something we have to be careful of while working on site! We're really careful around the rooms that have mercury in them--there are few that I didn't put in the guide also.

I was wondering about this too: they've found high levels of mercury in the water supply at Maya cities and believe now it contributed to the eventual collapse: https://arstechnica.com/science/2020/06/mercury-and-algal-bl...
Sadly, 1.3 MB is nothing on the modern web, especially for a static file.

Huh, if this exists and there’s already so many servers, maybe I should build a client instead.
What if being split up is a failure mode as well?
Glad that helped! Sleeping on it, it was even more likely that NB was correctly quoted by the still unremembered English historian as having taken issue with Tacitus’ (cf the famous convo with Wieland) coverage of one or more of the emperors’ motivational techniques
While I haven’t figured out how, it is my understanding that there exists a workflow where you have ipython/jupyter installed once, and then have them use the Python interpreter and modules associated with each project.

But I’ve never figured it out and instead have a `requirements-dev.txt` with Jupyter and Ipython in every project because they are so good to have on hand when developing
The problem isn’t people or colleagues asking for help, the problem is feeling entitled to your time exactly when they want it. No one would get any work done if no one had schedules and respected meetings at pre-arranged times.

Also, no one I collaborated with or on my team was ever the issue (except that one time at my first job when someone lied their way into a role, and constantly asked me to do their job). If my team member ever wanted to chat or distract me I had no issue.

It’s the fucking CEO who hasn’t bothered to talk to you for a month and ignore every email walking up to your desk, literally knocking on your table to get you to take your headphones off and give them your attention and saying “hey, when is this new feature gonna be done” when the project management software shows very clearly that everything is on track to ship at X date.

Really this isn’t about collaboration, it’s about people being entitled.
I'm eager for that feature too! The node graph engine recently got the ability to represent that concept, so now I just need to find the time to design and build the UI for it. I utilize that feature a lot in other software so it'll be really helpful to have in Graphite as well.

I am pretty sure matplotlib is not required. That is just a convenience library that improves the notebook experience if matplotlib is loaded. So you no longer need to run the magic function ‘%matplotlib inline’

You could do it even without cooperation from the python app using approach similar to pyrasite (though it is much easier with cooperation--just add a couple of lines).
I'm curious about users who do use something similar. I have an iPad pro, but I find either a notebook and pen, or butcher paper and pen to be far superior for capturing anything.

Can someone tell me how they're increasing their creative productivity with these outside of making illustrations?

I have a ton of ideas that I organize and illustrate, but I can't give up my pen/paper as I haven't found the killer combo yet.
Apple of yesteryear would issue a patch update model and let this feature cook until it was ready for release. Current approach is sloppy in a decidedly un-Apple way.
Not strictly. Over the past few decades I've occasionally but regularly seen evidence that "overweight but not obese" (BMI 25-30) might actually be healthier than a normal weight (BMI 18.5-25). In those studies obese did have a worse outcome than both.

IIRC mostly they had to do with seasonal sicknesses like the flu, the theory being that your body can burn the extra fat during periods you aren't able to eat well.
Airbnb is great until there is an issue and then it is a nightmare.

I think it will be like Amazons coming doom, death by a thousand cuts. You can have this horrible model that can't handle edge cases and until you burn too many people, it seems to work. But once you have sold fakes, or ruined (or added thousands in expense) vacations to enough people I know, your business is dead to me.
It wouldn't. So you wouldn't do that. It would be like giving an insulin pump to someone who wasn't diabetic. Why would you?
As long as old code continues to compile and run correctly on new compiler/language versions, I don't care what the committee does. From my point of view they should first and formost decelerate, so that there is at least enough time for compiler writers to keep up and collect enough experience between the standards. Cross-compiler compatibility has become an adventure since C++11. I only use a very conservative subset of the language to maintain compatibility.
Hi! I'm andy! I'm the guy who spent the past year making the Mothbox! I don't know how this got on ycombinator, but cool! We are working here together Let me know if you have any questions!

Some quick basics:
It's an entirely open source system made from off-the-shelf parts made so you can build one yourself!
We built it to help a set of community reforestation initiatives here in Panama! (

Existing automated insect monitors we checked out wouldn't work for us because:
1) They were REALLY BIG (like huge heavy suitcase size+)
2) They were really EXPENSIVE (like 7000-15000$ !)
3) There wasn't any info to build robust ones that could withstand months in the rainforest!

So we build one ourselves! We started with absolutely no budget, and the costs that people have noticed ($375) are really the cheapest you can find these parts (Pi5 + big battery + 64MP camera + really bright lights), and for instance are on par with the $200 just for the 16mp logitech webcam employed in many existing insect monitors!

We got about 20 of these out in the wild here in Panama already, and are literally building more in the jungle as I'm typing this!
Uh. So what?

At a European hacker con we had the custom of keeping crew badges in the first room to be occupied by us and our security. To get your crew badge, you had to get into that room without authorization.

Everyone worthy of being called "crew" did succeed.
Screens come in standard sizes. It might simply be that they can't fit all the parts inside, including the battery, without making the device bigger than the standard screen size and so you get bezels. Bigger devices have more room in them and many of the parts are just the same size.
The mainframe itself (or any other platform for that matter) is not magical with regards to latency. It's all about proper architecture for the workload. Mainframes do provide a nice environment for being able to push huge volumes of IO though.
Is there a body of research of "theory"?

I feel like the state-of-the-art algorithms represent incremental improvement moreso than an implementation of state-of-the-art theory. Kind of like Donald Knuth's dancing links, these improvements seem to come from "aha!" type exploration moreso than building upon a theory. Maybe that's typical? As a metaphor, it feels like with algorithms we are still Newton observing apples whereas there could be an entire Newtonian physics (of algorithms) out there. Some logic that underlies the field.

My understanding is that the abstract goal of any lookup algorithm is to map a series of bytes to an index such that the item at the indexed position can be dereferenced. The concept of hashing being to convert an arbitrary data type (string, integer, etc) to a sized integer. By abstracting the integer away to it's bytes, we have the above problem statement to solve. Other than that base understanding, I don't know what to research next in the field.
Fast Math basically means "who cares about standards just add in whatever order you want" :)
Why dilute your equity further?

You are the industry expert, so handling the sales side is critical as you are best versed in the factors that make your offerings special.

I would suggest using your network and hire somebody to handle the growing ops workload.

The desired cofounder you describe is very much like yourself and two people being responsible for approximately the same areas tends to lead to conflicts down the road. The key to selecting cofounders is for each to be responsible for distinct and separate areas of the business.
Super cool project. Looks like the short-term target use-case is running a Linux-compatible OS in an Intel TDX guest VM with a significantly safer and smaller TCB. Makes sense. This way you also postpone a lot of the HW driver development drudgery and instead only target VM devices.
Pithy and absolutely correct
What UI crate are you using for the GUI?
I expect the downvotes to be there because it's talking positively about rust, which is blasphemy! /j
Any history touted by the Church should be taken with a grain of salt. There are plenty of examples of how they manipulated things in their favor, and are prime examples of history written by the winner theory
Hey, yeah that was me. I spent quite a bit of time last year using pre-existing scanner positions to train nerfs/splats and didn't get anything that was usable, unfortunately. I ended up shifting to Unreal for a higher graphics tier, so if you want to see the Great Pyramid of Giza interior in the highest quality level, you can here: https://mused.com/netherworld-ancient-egyptian-afterlife-sim...

For Unreal I used a few methods but mostly conventional photogrammetry incorporating the lidar.

Ultimately, I'm hoping that downloading the file or some type of pixel streaming for web until the nerfs or splats -- or whatever follows them -- works out.
I learned a similar mantra that I keep returning to: “there’s never just one problem.”

- How did this bug make it to production? Where’s the missing unit test? Code review?

- Could the error have been handled automatically? Or more gracefully?
Lots of aircraft pilots love the iPad mini. Ideal sized tool for having strapped to a yoke, or to one's knee.
I have a public address and a private address. Gmail does well enough with spam filtering. I check it monthly and find some false positives. Nothing important though.

I can’t imagine spending more time on this, though.
Is Electron really so different in your experience than a PWA?

Personally, I always try to use a PWA when the app is otherwise offered via Electron.

If it’s going to depend on a browser engine, it may as well be the one I already have open and update regularly.
We use some dielectric grease when we have to make some outdoor connections and it works great here in the jungle, and it also has the bonus of keeping the leaf cutter ants from slicing up your electronics too!
> A lot of HTML's nowadays have 100 - 300 kb. That's only the HTML (!!).

I think you can probably blame Tailwind for that.
I would venture a guess that there is an equal proportion of company executives who would think that creating and using an email address like 'CompanyCeo@gmail.com' was completely fine - an awareness of internet scams is not correlated with business acumen!
This may somewhat surprise you, but I would ask the same for people in the 30s. 40s even, at this point. Freezing someone at that age doesn't sound appealing to me. At all.

So the heart of my question is why do we view "defeating aging" as the same as "living longer?" Or is this something where the target age that people would want to be generally coalesces on a common number?
I don't know the details, all I know is because of that I can't currently install FreeCAD from Fedora repositories which is super annoying, and IMO not the fault of either Fedora or FreeCAD...
To be fair the framing of “carbs are evil” is also lazy. The root cause of most cardiovascular disease and type 2 diabetes is obesity due to excess calories of any sort (although once you’re diabetic or prediabetic carbs are a HUGE problem no matter what).

The modern lifestyle is incredibly sedentary and every civilisation is built on staple foods that can feed hours of manual labour (with modern snacks thrown on top).

Calling a major food group evil is just a good scapegoat because it’s much more palatable than telling people that they don’t move enough and eat too much food.
Well, you know what to do - just sell a system that runs COBOL on an x86 cluster or Kubernetes or whatever, and you'll make billions!

Be sure to allocate me a bunch of shares for giving you the idea.
Isn’t Postgres a fairly capable IAM provider, all things considered? I’d their access control mechanisms at least as much as a run of the mill external backend’s.
It works as you described: Texturing the mesh "live" as you move through it. It does use Three.js as a base, but needs custom shaders to make it 60 FPS.
did you see France raising their cost estimate for 5 reactors to $73B? France, the shining beacon of nuclear energy.

by the time they build it, the cost of renewables will halve, and their actual cost of nuclear will have doubled again.
Seems like I'm the only person that is happy to keep all my old synths in the closet and do everything in my DAW. My DAW, associated VSTs, and their ease of us is like one of the only good things about living in the future.
Note that I said that it would make sense a CRLF command too, as in: in addition to separate CR and LF commands, which are useful in their own rights.

I also strongly disagree with the author that LF is useless.

So many times in code I need to type:

Function blah(parameter1 = default1,
parameter2, ...)

It would be super nice to move down from the beginning of the word "parameter1" down to the next line even when it's empty to start typing at that position.

Sure, there is auto format. But not in this comment box.

And what I'm talking about is exactly what LF was meant to do!

I want all my text boxes to support that, and to have a special key on my keyboard to do it.

Eh.
Sleep deprivation might have led to {2->1}, but the almost iambic lines you 404’d on were borne of a restful sleep under fully endogenic (biochemical) influence. (Thats why you 404’d)

Yes, that's the part I found terrifying too. I'm reluctant to extrapolate that experience to the whole country, but it's certainly concerning.
