Link technologies in today’s data center networks impose a fundamental trade-off between reach, power, and reliability. Copper links are power-efficient and reliable but have very limited reach (< 2 m). Optical links offer longer reach but at the expense of high power consumption and lower reliability. As network speeds increase, this trade-off becomes more pronounced, constraining future scalability. Weintroduce MOSAIC,anoveloptical link technology that breaks this trade-off. Unlike existing copper and optical links, which rely on a narrow-and-fast architecture with a few high-speed channels, MOSAIC adopts a wide-and-slow design, employing hundreds of parallel low-speed channels. To make this approach practical, MOSAIC uses directly modulated microLEDs instead of lasers, combined with multicore imaging fibers, and replaces complex, power-hungry electronics with a low-power analog backend. MOSAIC achieves 10× the reach of copper, reduces power consumption by up to 68%, and offers 100× higher reliability than today’s optical links. We demonstrate an end-to-end MOSAIC prototype with 100 optical channels, each transmitting at 2 Gbps, and show how it scales to 800 Gbps and beyond with a reach of up to 50 m. MOSAIC is protocol-agnostic and seamlessly integrates with existing network infrastructure, providing a practical and scalable solution for future networks.

>So, what's the the right form of regulation to address this?

I don't know, but the ones I've seen so far do not interest me.

>Are you against regulation?

I'm against bad regulation, yes.

>Or are you here just to discuss aesthetics?

If you think objections to "you're either with us or against us" and "we have to do something" attitudes are merely objections over "aesthetics", then yes.

The good news is that these economic problems are entirely the result of bad policies and can be reversed.

If we were to also raise broad based taxes, it would allow the Fed to cut interest rates, stoking long term investment, loosen up the housing market (which would allow more people to move), lower the Federal deficit, and improve the trade balance (as if that actually mattered).

The last thing I want when giving voice commands is a realistic human conversation. Just read back the instructions I gave and ask for verbal confirmation.

I commute on a motorcycle, and a decade or more ago, when I had a Nokia phone running Symbian, I could tap the button on my Bluetooth intercom, ask it to call someone, confirm it heard me correctly, and complete the call. I could then tap the button, ask to navigate to an address, and get directions.

With modern phones, when they mishear you, they immediately call the wrong person, out of "convenience". When I try to navigate with voice commands, prompts show up on my phone display, which I cannot tap or even see, because my phone is safely stored under my seat.

I have stopped using voice assistants, because the more technology that goes into them, the less usable they get. More capability isn't always better. There's a reason air traffic controllers only use a small subset of English vocabulary and grammar.

Many north African and middle eastern states tried to switch to democracy and that did not go as planned either, would that mean that democracy does not work?

Any policy (UBI or others) must take into account the state and potential of the country. Based on the Gulf state UBI example (if correct, I did not check) it would mean that with their initial conditions UBI will not result in developing skills (although, thinking of it, maybe their purpose of giving UBI was close to the one observed, their ruler don't strike me as very progressive).

> not supposed to think about this

Not supposed to think about it according to whom? Who's telling you that? Why are you listening to him?

The US has some of the best public schools in the world. The US also tops the world on spending per student, especially in poorly performing areas. The education crisis disappears when you control for demographics.

It's right to notice that and remains right no matter how much pushback you get from people who've been pushing the same broken solutions for 50 years.

Congratulations for adopting an independent perspective here. We need more of you.

I think the root of the problem is that education is no longer seen as a fundamental foundation to a better life. Kids aren't doing well because kids don't care. They don't care because their parents don't care.

Why don't they care? I think for many, they have given up any hope that a better life is possible. So education isn't the key, because nothing is the key, because the door doesn't even exist.

I would very much be considered someone who doesn’t “need” the funding, but when deciding between having a 3rd child or just sticking with 2, I wasn’t comfortable enough to afford 3 in daycare and helping 3 through college. However, I expect my offspring to be significantly greater economic contributors to society than the average. It would have made sense for society to fund my childcare to incentivize me to populate the earth.

You seem to be under the impression that these figures are exclusively sourced from employers, but they are not. They are sourced in part from a survey of 60,000 households every month, where each household in the the survey for several consecutive months. Here is some information about non-response rate: https://www.bls.gov/cps/methods/response_rates.htm

Ignoring the complicated history of the rural areas, I periodically drive Route 66, Since the early 2000’s, the bit in New Mexico has basically been eaten by climate change. I can’t imagine how much damage the encroaching desert (badlands? What’s the word for a desert that’s drier and dustier than before?) has done to the local economies.

They weren’t doing well before, but it’s not been trending well.

Having said that, Albuquerque is nice. Props to the Navajo nation for helping out with early COVID vaccine testing.

> I find it dubious that adding the people who don't find it financially feasible to use childcare to cover working hours will generate tax revenue to cover this due to the low income and low tax nature.

You can actually think through your belief. The announcement provides a concrete number: $12,000 per child. Do you generate $12k in tax revenue? Note that this means direct and indirect tax revenue, not only from your job and what your employer earns from your work but also with your own expenses that you can cover by having a job.

> There are 23 entries since 2015 on that page, Hollow Knight included. By definition, it's one of the best 23 games during that period, according to that specific list.

Okay, but that's an argument that it's considered one of the best games of the last decade. Hopefully you can understand my confusion.

> It sounds like you're making up bizarre exclusionary criteria to discount the fact that Hollow Knight is widely regarded by many people as one of the best games of all time, which explains the hype behind Silksong.

*shrug* I don't think it's that weird. This certainly isn't something I'm coming up with on the fly. I've felt like this for a long time, as have the authors of the many articles complaining about the meaninglessness of the even larger number of "best of" lists.

> This doesn't mean you have to like it

You've made several comments which make it sound like I'm arguing this because I don't like the game. I'd appreciate you not doing that both because I did quite like it and because it implies that my feelings about the game are biasing my argument. I'd make this same argument if you'd used that Wikipedia article to support your feelings about Red Dead Redemption 2. I'd probably personally consider that one of the best games I've ever played[0] but would object to using its presence in that article as proof that it was widely considered to be one of the best of all time.

[0] Honestly I'm still not sure if I should compare it to other games I've played or put it in its own category of interactive movie. It was incredibly good, but the parts I think of as being the best are the performances and the technical achievement and clever landscaping of the game world.

For me at least, it's a general dislike of the wider educational system. My parents taught me to read, play chess, multiply, and write in cursive before elementary school. I didn't really learn anything at preschool or kindergarten, and I imagine daycare would be worse for my educational development. Maybe it's useful for social development? but at least for me I was always pretty independent (even in kindergarten) from the other kids. Not in an isolated way, I just preferred doing my own thing.

The incentive alignment of a stay at home mom who's taking care of 10-15 kids (which is typically what these operations are) to add some extra income is way better than a "real" operation that's got one manager and some min-wage employees running around herding 15 kids each while simultaneously trying to keep the state off their back.

Don't get me wrong, I don't expect the former to have ADA compliant doors or hot water that meets state regulations but the "give a fuck factor" is just so, so, so much higher when someone is working out of their own home, one of their own kids is in the mix, the rest of them are kids of a friend or friend of a friend, etc, than it is when your kid is being looked after by some 20yo college kid who's doing this part time.

I'm currently a senior software engineer with 5 years of experience. I've worked extensively with F#, C# and Clojure in distributed systems and I feel at home with functional programming. I have helped companies build scalable and maintainable systems using technologies with a bet of good understanding of their function and documentation (which most people usually don't read). I worked from microservices to monoliths, from Kafka to SQLite; I like to be ecletic in my toolchain, as even if I do not use something directly, there's hardly nothing one can learn from it. I have personal passion projects in OCaml and Erlang where I try to apply theory-compliant relational algebra. I already managed software teams and I know how to build a near-zero maintenance cost system from scratch.

The equilibrium of ecology, without human interference, could be considered perfect efficiency. It's only when we get in there with our theories about mass production and consumption that we muss it up. We seem to forget that our well-being isn't self-determined, but dependent on the environment. But, like George Carlin said, "the Earth isn't going anywhere...WE ARE!"

It's quite telling how much faith you put in humanity though, you sound fully bought in.

- The Pandemic really set that generation of kids back, particularly kids who were in elementary during that time.

- Public school is essentially daycare. They try to integrate special education students more into the regular classrooms, but the teachers end up spending disproportionate time dealing with them and their behavioral issues, which hurts learning for regular students.

- I don't have strong, set in stone opinions about Common Core, but it's approach is certainly hard for parents trying to catch their own children at home. Eg. there is no emphasis on memorizing multiplication tables, but rather it's on learning rather esoteric and hard to remember (albeit valid) math algorithms.

- The teachers are generally poorly trained, poorly motivated, poorly paid, poorly educated, and poorly adapted to teaching students.

- Learning high school math has been enjoyable. I only took up to geometry in high school, but they are doing much more advanced math. I don't know any of it, and they barely do. So it's been fun learning it and then having to teach it to them in the matter of a day or two. Being a programmer has been exceptionally useful in that regard.

As someone done with the need to code for a living, I think it's both sad, and good, that we don't have to content with machines with a few K of RAM, and cassette storage (or worse yet, toggle switches and punch cards/paper tape) ((or worse yet, wiring up ENIAC, a process that sometimes took days between setup and debugging)) (((or worse yet, figuring out how to arrange all the IBM punch card machines to do math for the Manhattan project)))

or people running mechanical calculators

or people doing math by hand

or people doing math without zeros and the decimal point.

Yes, it's sad that a skill might be subsumed into the technology stack. But do any of us miss having to really, REALLY understand what's involved in creating/sending IP packets across ethernet, or WiFi?

Sure, the tools are unreliable, but they'll get better over time. There will still be people trying to eek out the last bit of performance, or get rid of another byte of code, the Demo scene will live forever, in some fashion. It just won't be a work requirement any more.

We're the accountants manually recomputing spreadsheets on paper. We call ourselves "Software Engineers", well, now it's time to actually Engineer Software.

> As in, things were fine before we had commonplace tooling to fetch third party software?

In some ways they were. I remember how much friction it was to take a dependency in your typical desktop C++ or Delphi app in late 90s - early 00s. And because of that, developers would generally be hesitant to add a new dependency without a strong justification, especially so any kind of dependency that comes with its own large dependency tree. Which, in turn, creates incentives for library authors to create fairly large, framework-style libraries. So you end up with an ecosystem where dependencies are much more coarse and there are fewer of them, so dependency graphs are shallow. Whether this is an advantage or a disadvantage in its own right can be debated, but it's definitely less susceptible to this kind of attack because updating dependencies in such a system is also much more involved; it's not something that you do with a single `npm install`.

> If a video isn't worth waiting 10-60 seconds for, is the video even worth watching?

I won't know that until the video starts playing. I'm not watching a 90 minute movie here and I don't know if the video I'm about to play is the one I want. Spending a minute setting up a 90 minute movie is very different than spending a minute waiting for a video to load that I'm likely going to spend <30 seconds on.

Maybe I'm learning how to use certain software and I'm trying to find a video that demonstrates how to use a specific feature. In that case I might be clicking through 10+ videos to find the niche thing I'm looking for. If I was just vegging out on Youtube this wouldn't bother me nearly as much.

And don't forget that the time penalty doesn't only apply to the initial load, it would pause and fake-buffer every time I jumped around the video.

The full story is:

Specialized foreign workers were brought in for repair and specialized work. Korean immigrants are able to come in on ESTA visas for 90 days. No issue there. Labor union claimed the workers were doing union non-specialized work and this broke their visa grants.

Suppose that the plant made special workers do non-special work, the hammer does not fall on the workers. It falls on the plant. Yet ICE was brought in to hammer the workers. This is a big screw up in the legal procedures department.

I don't criticize anyone but this administration is a hot mess. And too arrogant to admit it.

Given that ratings agencies were brought up it's worth adding a bit more detail here.

Thames' debt is C-grade because it recently defaulted on its debt. How is that possible given that its debt servicing costs are not unusually high? Normally you'd expect interest costs to go up well before default. Well, on the surface level because it couldn't raise more money from investors to meet rising costs. It couldn't do that because Ofwat keep fining it for "underperformance" whilst also refusing to allow prices to catch up with where they used to be in the past. Investors refused to put more money in unless a 40% price rise was allowed by the government, but the government likes to boast it has forced prices 45% lower since the 1980s (in real terms). Government doesn't budge, investors go on strike = default = downgrade.

There was waste under state ownership but probably not half of every pound spent, which is what forcing prices to nearly halve would have required.

Under the Tories it seems to have been believed by investors that eventually Ofwat would be reigned in and the financial pressure on UK water companies would ease. That didn't happen, instead the Tories imploded and Labour won. Both ratings agencies say explicitly that this is the reason they consider Thames' outlook to be either stable (at best) or negative:

"We revised down our assessment of TWUL's business risk profile to satisfactory because we now consider that U.K. water companies will operate in a less supportive regulatory environment"

Less supportive regulatory environment is ratings-speak for "because we think the left will shaft Thames and its investors".

This outcome is the opposite of the fantasy being peddled in this thread where investors have been extracting great wealth from Britain. It's the opposite: investors are getting hosed by the government. They're literally losing the money they put into Thames Water because the government forced Thames to spend it all on making water artificially cheap in an unsustainable manner.

Understandable. I feel sorry for the Korean workers who were caught up in this. Hyundai should be held responsible for illegally importing/trafficking them, they should keep their jobs, as it's not really their fault. They were probably lied to by Hyundai. They're the victims here (as well as the American people, but that's another story).

I live in the US in New Jersey, and here a big problem was the State flooded school districts with money during Covid with no material oversight of its spending.

The end result was huge increases in spending. But not on education. The money was spent on more MacBooks, more iPads, more buildings, more smart TVs, more consultants, more School Bullshit System as a Service, more scoreboards, more $50,000 signs in front of schools.

Meanwhile the good teachers are fleeing the system and test scores are plummeting as schools focus more on day care and “social justice”, and a declining emphasis on teaching core subjects and learning in general, coupled with social promotion where everybody gets a C or higher, and 80% of the school gets on the honor roll (spoiler alert: our district is not some outlier where 80% of the kids are geniuses).

Schools have very little to do with teaching, and really are just about baby sitting and trying to correct social issues.

Oh, and endless buckets of tax payer money with meaningless oversight.
Show HN: I made the ultimate pixel art character customization program [video]
by flinkerflitzer | 2025-09-09 16:15:51+00:00
I'm Jordan, the developer of Top Down Sprite Maker. Like the name suggests, my program is a pixel art character customizer. But wait, there's more! Unlike pretty much every other program in that niche, my program supports multiple "sprite styles", and let's you create and share your own. A "sprite style" combines an art style, supported directions (whether 4, 6, or 8), animations, layers and assembly rules into a cohesive system of character customization. Sprite styles are defined by a single script file and packaged as ZIPs. They can then be shared, uploaded to the program, and immediately used to customize characters and export sprite sheets.

The video description has lots of useful resource links as well if you want more information.

Thanks for your time. Let me know what you think!

It's not a problem that Docker Compose can be used and a configuration is provided. What's an indicator of a dependency problem is when it's the only way to deploy the software. If, instead, they could say "all required dependencies ship in Debian at a sufficient version to meet our requirements" then that would be ideal (Debian isn't a hard requirement for me, but I use it as an example since it sets a bar similar to the one I want software I deploy to meet). Or even just "nearly all dependencies except this one" would be much better.
