Salaries:
Pretty abusive salaries for a non profit but that seems to be pretty much the standard nowadays, right?

Bandwidth:
I took at quick look and see that chat.signal.org resolves to AWS. If they are paying AWS for a lot of bandwidth, that is very expensive. Let's take a quick look:

They say they use 20PB per year of bandwidth for voice calls alone, this costs them $1.7M a year.

According to AWS pricing for great customers (suckers) of over 150TB per month, the cost per GB goes waaaay down to $0.05, yay. 1.6PB per month is 1600000GBs, that's $80K a month and therefore $960K a year.

Very roughly, a 10Gbp/s link to the Internet, from a Tier-1 provider will be around $800 (eight hundred dollars, you're reading this right) a month in a low-bandwidth-cost country like the US, possibly double that in say Asia.

A 10Gbps link fully utilized (minus some overheads), translates roughly to 3 Petabytes per month, that's 36 petabytes per year, almost double their advertized amount of bandwidth needed for calls per year.

So we have ~$10K a year (negotiable) for 36PB which is double their bandwidth needs but let's not forget that AWS graciously (geniously) charges for egess only, this means that their actual bandwidth needs are 40PB per year for whatever they are reporting. So we have $10K for 36PB a year vs $960K a year for 20PB (actually 40PB) of bandwidth from dear Amazon.

1. Not sure why they are saying the cost is $1.7M per year.
2. Even at 960K it's daylight robbery.
3. AWS makes an absolute killing on bandwidth costs. Best. Business. Model. Ever.
4. Don't these guys have a Devops pro at $300K+ a year? weird :)

Servers:
I won't get into the numbers here as that's a lot more involved, and impossible without more data, but buying and maintaining your own infra, or possibly easier, renting it, would still be quite a lot cheaper than using AWS.

Takeaways:
- Storage is something you should buy and maintain (Thanks B!), you swap out old/dying storage devices. See Backblaze.

- Bandwidth, compute and storage costs at your favorite CSP are absolutely f'ing *outrageous*

- If you care about your money, your bottom line, do things differently than the *insane* mainstream way of clickity-click on some UIs to provision services without understanding what's really happening under the hood (not saying Signal doesn't understand that part, I'm sure they do), or caring about the added costs of whatever gets so easily "added" to your "infrastructure".

- By having your stuff on a CSP you don't even have "infrastructure", but that's juts me.

Anyway, I do love Signal, what they do and what they represent. Keep up the good work.

Signal, mail me at m aaaat zynk.it if you'd like to talk.
Never seen used in the practice though. One of problems AFAIK - most switch default to dropping jumbo frames. You can enable but if you'll left one unconfigured for some reason you will get hard to diagnose problem. The same with end hosts - they (inside a given L2 domain) should have the same MTU and if you'll left a box with the default MTU you got a problem.

To make jumbo frames easier to use switches should forward them by default and hosts should accept frames large than MTA (but send MTU sized ones).
To all of those arguing spectral distribution doesn't matter:

Consider Spectral Reflectance.

We use only three wavelengths for LED displays that manage to show us millions of colours, HumOns are trichromats right? So the thinking goes - we should also be able to use narrow band light sources to illuminate our physical environment with the same results. But this is just not how illumination works in the physical world.

The difference with displays, is that we are looking directly at the light source, the light source is the image; with lamps, we are looking indirectly at reflections from our physical environment, and physical surfaces reflect different wavelengths with different intensities, i.e they have a spectral reflectance curve (and these can be pretty crazy, not simple smooth curves). The other key detail is that our eyes are not narrow band, they merely quantise broad spectrum into three colours. So just because some surface might reflect brightly at 480nm but not 420nm (humans peak sensitivity), doesn't mean we don't see it, it still looks blue, just less so. The issue is that most standard LED lighting spectral output (phosphors and all) might focus on 420nm so that it looks white, but might have a dip at around 480nm so that reflections on that particular surface appear less blue than they should.

This is the issue people are experiencing when some things look too dark or too grey, surfaces have complex reflectance curves, most cheap LED lights have extremely poor spectral distribution and they can basically miss those surfaces. The more spikey and narrow band a surface's reflectance curve the more likely a narrow band light source is going to miss the reflection wavelengths and do a poor job of illuminating it.

[edit]

To be more fair to LED lighting, the comparison I made above is not entirely fair. Unlike a monitor's output LED lighting actually attempts to get broader spectrum output by adding phosphor layers to convert wavelengths of the LED, it's just that most ordinary price household LED lamps are still very poor in their distribution. It's not impossible to generate a better spectral distribution with LED sources, it's just expensive, and requires more than one LED source wavelength+phosphor combination. The other issue with cheap LEDs you might notice is that the phosphor layers tend to degrade, changing the colour temperature over time, and the inverters commonly break before the filament resulting in a very short and flickery lifetime.

I haven't used these, but this thread instigated a search, seems like there are broad spectrum LED manufacturers like this one [0]. Their target customer makes sense... Some art will undoubtedly look weird in narrow band light.

If you are from a very small country, maybe... But there's a lot of mid-sized or other big countries who just have the power and don't do any of these regulations.

Brazil basically cloned GDPR and it worked (LGPD). For example, look at this Samsung tool: https://imgur.com/a/ycgkSCI
Language is about knowledge.

If it wasn't, what would we be doing here?
Assuming this is true the impact of this very defensive brand position is that being defensive and risk averse IS the brand. In the long run your actions speak louder than words.

I do think it's a bit ridiculous (although quite possibly true) that they would be wary what advertisers think. The ad platform is full of terrible AI options already.
Quiet resignation.
Not even doing a great job of that now that so many subcontractors quietly source from China.
I get that you have a beef with an anti-blockchain heretics speaking blasphemy in the public square and are compelled by your religion to chastise them vigorously, but you aren't helping keep things on topic either.
USB-C would certainly work, you just need the right (wire) mounting device behind the plug. It's unlikely to be very slim though.
It would actually be amazing if you could do that—somehow stub dependencies with your own libraries.

Because the number of times I’ve needed a left pad lib is literally 0, but other, more useful libraries always have it as a dependency.
Ah, the classic side quest into a seemingly useless project - I can relate. Spending three years on a coat hanger sounds just like the kind of rabbit hole I'd fall into. It's usually more about the journey and scratching that itch than the end product. But turning it into a business? Now that's impressive. Most of my hyperfocus side quests end up as forgotten userscripts or abandoned github projects. Kudos to her for not only sticking with it but also turning it into something tangible and potentially profitable!
40% of 3% is 1.2%, where’d you get 0.9% from?
Can’t this already easily be accomplished and even flatter to the wall simply by using a hanger with a swiveling head? Only downsides compared to this invention would be the way the different items nested together and the fact that they stuck out to the sides 50% of each hanger at the ends?
Carving My Own Path
Apparently 1/3 of property chains fall apart before completion - that's a lot of wasted money on searches and solicitors.

> I don't see how reforming (how?) a system that is simple and cheap would help solve the "housing crisis".

Is there effective utilisation of the existing housing stock? Encourage people to move to ensure that their home meets their current needs. E.g. retired couple, children have left, so their current house is oversized.

Making property transactions less stressful for people would assist with this. I'm certain that there are people out there who would be open to moving, but CBA with dealing with the stress of being stuck in a property chain.

How? Just look up north to Scotland. Not a perfect system (e.g. "offers over"), but ahead of what England has to deal with when it comes to transactions.
A fast 50% sort could be very useful given the right circumstances.

Every great product needs a product expert and a technical expert. The two overlapping is a magical opportunity to create something not only new, but right.
One issue with that is that electricians can sometimes be brutal on Cat5 used as a phone line. I’ve had drops that were basically unusable as ethernet because some of the pairs were damaged, even though the phone pair in use was fine.
Attempts at cloning are often the dirty secret behind much lauded creativity.

I like the stories of unique art/music that was created because someone was trying to clone something exactly... but despite their best effort, they just couldn't get it right and ended inventing something new that people loved anyway.

We just have to make sure we are pretty bad at the cloning!
Decorative Edison incandescents. They're exempt. I like dim lights anyway. Just watch out for LED ones that they're trying to pass off as incandescent.
It's not just the waste heat. If you're well positioned, the radiant heat off an incandescent can heat a human body very effectively. Remember the "heat lamps" some bathrooms used to have? The same effect is found in regular lighting incandescents, especially if you're directly below an overhead fixture.

"Radiant heating of humans" is rather substantially more efficient, in terms of "human happiness per watt used," than heating the entire house. I've got some radiant heat panels that get used heavily in the winter, and there's nothing like a good radiant kerosene heater (mine is 10k BTU, about 3kW, almost entirely as heat) on a cold winter night.
By that definition of knowledge, I don’t contain knowledge either.

I’m clearly keeping track of how strongly I believe a variety of things. Not how I started believing them to begin with, however, so I lack the justification. And in a lot of cases, the lost justification would have been: “Because someone else said it, so now I’m aping them.”
> Capitalism repeatedly creates situations where new things are created that make everyone's lives better, and existing things get cheaper and better over time.

> everyone's lives better

> things get cheaper and better over time.

Oh, fuck off with that bullshit. Capitalism may appear to thrive when living in a first-world country, but only does so through exploitation and cutting corners. More to the point, isn't it funny that despite capitalism being pretty much the de facto economic system of the world only a few countries are actually deemed worth living in? No, some abstract 'informed exchange of currency' didn't magically cause things to appear out of thin air. People make things, and they are almost certainly underpaid and overworked. Behind every AI model there are X poorly paid workers around the world that curated the data that it needs to function. Behind every piece of clothing there are Y poorly paid workers in Bangladesh that made it. And behind every rechargeable battery there are Z Congolese kids risking death inside a mine in search for cobalt. We might try to (and often do) look away, pretend that those are the unfortunate results of corporate blunders that seldom happen, but they're not. Invisible exploitation is what makes the kind of lifestyle that is available in first-world countries possible.
You can hire someone to run the cable for you, it's not a terribly hard job. The most expensive part is getting out there.

So keep an eye out for a neighbor who has an electrician doing work and maybe see how much to just move the cable.

Drones is overthinking it.
You can invent a programming language on the spot and it will help you write programs in it.
Helpful info thanks
Agreed. A good example of this (in Python) is to explore solutions to problems that use decorators/a more functional style vs. solutions that use classes and a more OO style. Usually both are totally good. The code GPT generates can be totally functional, yet inappropriate in context. Another good one is asking it to translate code from JS to a language without real “interfaces” and see if it uses a base class pattern or not. I review junior devs and lecture them extensively about stuff like this. (Yes, I am fun at parties.)
For me (i built something similar) the main advantages where:

- I control my own data
- It is e-ink, not glaring into my face
- Screen is way bigger
- Screen is hanging on the wall, I do not have to look down
- Less energy consumption of course

and most importantly:

- Google home displays are not actually helpful at all in this respect (we have one in the kitchen too) as they do not show calendar info well at all. For a family of 4 you need to be able to look at the entire week or more to plan events quickly

PS: I use a 10000mAh battery in the frame, so no cables
A typical use-case is glancing at the calendar during a phone call for example
While we avoid low quality re-print/syndication, it is normal to submit and discuss secondary commentary on HN. Think of all the “X did Y, here is why it matters” style blog posts.
You seem to be making some kind of category error here as "Hydro" is also renewable.
Ethernet is a family of standards which encompass physical wiring, connectors, electrical/optical signaling standards, and logical layer standards. It absolutely has to do with the cables as well as the signaling.
This is made even worse by ai companies recycling the code.
The problem in this case is that the seller's agent takes the whole 6%. It's not that they only take 3% (which is the most disgusting part here).
I'm in the market for some lighting now and my dream is to have OLED lights:

https://www.omled.com/product-page/omled-one-s5l

They're eye-wateringly expensive and not particularly bright, but the spectrum is reportedly much friendlier than LEDs and they're currently making their way to the automotive world, so prices might decrease over time.

A more realistic proposition might be red phosphorus LEDs:

https://store.yujiintl.com/collections/high-cri-led-technolo...

The key thing is that CRI doesn't tell the whole story about a light's spectrum, as it's an average of 15 test colours and R9 - red - often scores very low, producing a visibly worse image despite high CRI.

Look for lights that advertise high R9.
> There’s no point in lamenting that people act entitled.

There is: it discourages people from acting entitled.
I dunno about that. There's a lot of Python out there with worker threads dumping their output into a shared "results" dict on the assumption that those insert operations are atomic.

Actually the article has statistics and sourced infographics backing up its point. You can’t challenge those because by not reading it you haven’t seen them…

So I’m left either trusting the Wall Street Journal or the anecdote of someone who didn’t read the article. Gonna go with the former in this case.
Coinbase, Haun Ventures, AI Foundation Remote Accelerator
Coinbase, Haun Ventures, the AI Foundation, and Fabric Ventures have partnered with the Bentonville, Arkansas, tech community to support Web3 and AI startups. This is a compelling example of how Bentonville is becoming known as an emerging tech hub because of the world's wealthiest family building and amazing place to build. It's also interesting because Arkansas representatives are power players in Washington for the Congressional Sub-Committees working on crypto and AI regulation.
Wow, a truly rare instance of literally eating your words!
The FCC admits they could not identify any intentional discrimination.[1] So they went further and adopted a "disparate impact" standard which means you don't even need to intend to discriminate. And unlike disparate impact in other areas of law, where having a "legitimate non-discriminatory interest" is a defense, the only defense here will be "economic or technical infeasibility," and they explicitly rejected profit maximization as a way to satisfy that standard. So say you're an ISP deciding whether to invest the same money into building fiber out to one of two areas, one where you'll make 1 million dollars a year and one where you'll take 2 million a year, and you make the rational decision to build out to the more profitable area. The FCC can fine you for that because it turns out the less profitable area was more black and the more profitable area more white, and it was economically feasible for you to make less profit, even though racial factors had nothing to do with your decision. If you think through the implications of this, it's a requirement to engage in discrimination/affirmative action in every single business decision you make. And even then, it's impossible to know whether you're ever in compliance. How much profit do you have to sacrifice in pursuit of racial equity? A quarter? Half? Two-thirds?

[1] "As noted above, there is little or no evidence in the legislative history of the Infrastructure Act or the record of this proceeding that impediments to broadband internet access service are the result of intentional discrimination based on the criteria set forth in the statute." https://docs.fcc.gov/public/attachments/DOC-397997A1.pdf Paragraph 47
Customer service is great too, I had one bulb die after about 9 months and they replaced it for free (and I didn't even ask, I just asked them what I need to do and the responded with a message saying they've gone ahead and shipped a replacement).
I've not. Honestly, I'm not in the market for tool shopping at the moment, I need another honeycomb-style moment of "this is incredible" to start looking again. I think it would take "Honeycomb, but we handle metric rollups and do logs" right now.
In theory. Anyone can sue anyone at any time for any reason. Winning is different. In reality if you don’t have a bottomless legal warchest, good luck.
A nice application for this might be places that have reservations that would be helpful if displayed. For example, tennis courts, squash courts, etc. People make the reservation online and, when they get to the facility, often don't remember which court they've reserved. Having it on a display would avoid having to look it up on the phone.

Those sorts of places also might have a budget for something like this.
How does this work with both? Is there a defined band plan standard that cable operators know to avoid? Do you need to install a notch filter on the line coming into the house?
Fair. Though I think it is a safe to say that the intent is to document the software moreso than the use of it. Mainly going off of all of the programs on Knuth's homepage. TeX and METAFONT are both the same. The literate program is distinct from the user manuals.
I think there are some trains like this. But unfortunately it is rare. Even for bicycles, ÖBB NightJet has just 3 places (with exception Vienna-Amsterdam, that has more).
Russia's ability to wage war on Ukraine is enabled entirely because they have a nuclear arsenal. The war would have been shut down almost immediately by the US / nato / etc. if they didn't have that threat.

But you do not need to discuss that. Rather suppose ad-blockers are working less effectively under v3, leading to additional ads being shown. That would increase the attack surface.

If ad-blockers really will be less effective under v3 remains to be seen. But do you think it is an unreasonable perspective, given the technical limitation?
Agreed. The 1984 reference was more about how the truths of both countries and the relationship between them reeks of newspeak (i.e., propaganda). It all feels so staged so contrived.
I think the whole point of the philosophical concept of "bullshit" is that it's orthogonal to the truth. It doesn't matter whether the words end up being correct or not correct, it's still bullshit because the speaker doesn't know or care if it's actually true.

Pinball implemented using Squint, a ClojureScript dialect
A Museum is fancy storage for unused things. But Emacs is full of very useful and still usable parts, and a useful philosophy and prospering culture. What's wrong with spreading all this to other spaces, and letting other people learn about them, making them more accessible? Works well for (neo)vim. They have moved beyond lousy vim-key-implementations and today people are able to learn about modal editing and composable commands on a good level.

For as long as I may remember, I've had the same problem. I detest artificial light and I'm a sucker for the twilit, moonlit, and candlelit. Seems like modernization means having every single dark corner illuminated.
