>Why not?

I'd be fine sharing my location with my immediate family, but they refuse it. When they wonder how close I am to being home, it isn't supposed to be such a serious thing as to have my precise GPS location. It's a reason to think about me or message me.

I've come to think that it's one of the many "problems" that many people don't actually want to solve, and being so heavily connected is taking away some of the "magic" of social behavior and replacing it with efficiency.

As a random example, waiting for a date to show up is probably more exciting than having a precise read of their location. Or, when my parents were visiting, they'd often say they were just thinking about how I'd be getting home soon.

The nice thing is that everyone has the ability to decide if they want to share their location or not. But even on social media, I only reveal my current location when I'm somewhere that I'd be open to running into people. Otherwise I intentionally wait till I'm somewhere else before posting about where I was.

I worked on one of the Linux live CDs (Linuxcare bootable business card / LNX-BBC), which we designed to fit in 50 megabytes. I remember being kind of jealous of the QNX floppy, because I felt that it had about 25% as much software functionality as we did, but in about 3% of the storage space!

I mean, basically we could interact with a lot more hardware, support more file formats, filesystems, and network protocols, and had more high-level scripting languages. But there still seemed to be a huge disproportion where the QNX floppy was just so much more space-efficient for what it did.

> The $2,000 plug-in solar system installed on Dwyer’s backyard deck in March consists of two 400 watt panels, an inverter, a smart meter and a circuit breaker. It saves him around $35 per month on his power bill because he is consuming less energy from the grid, but he said reducing his carbon footprint was his primary motivation.

so about 5yrs ROI

And in germany a similar 5yr ratio (With some german cities subsidizing installation):

> Weyland spent around $530 for his 600-watt-capacity system. While he’s happy with how his south-facing panels perform during balmy weather, such days are rare in northern Germany. He estimates that he’ll save around $100 in annual electricity costs and recoup his investment in about five years.

The article mentions the main motivation in Germany is also climate change and a feeling of independence, not so much economics

One thing it's doing is jacking up electricity rates for US States that are part of the [PJM Interconnection grid](https://en.wikipedia.org/wiki/PJM_Interconnection). It's a capacity auction price that is used to guarantee standby availability and it is [up significantly](https://www.toledochamber.com/blog/watts-up-why-ohios-electr...) at $270.43 per MW/day, which is far above prior years (~$29–58/MW/day) and this is translating to significantly higher consumer prices.

A typical phone battery has a capacity of about 13.5 Wh. Assuming a converter efficiency of 90%, it takes 15 Wh (0.0015 kWh) to charge your phone from an outlet. Assuming an electricity cost of $0.39 per kWh in San Francisco, that's 0.58 cents ($0.0058) every time you charge your phone using the solar panel.

By Grabthar's Hammer, what a savings.

In another comment, you said "You want to cry me a river over militarization of police and following the basic rules of engagement, I am all ears". I don't know if that was just a ploy to appear reasonable, but if you really care about that as you purport to then you already know the answers to those questions.

As a libertarian, I've had enough with people feigning condemnation for government/police overreach/unaccountability while writing comments that condone it.

I paid a subscription to Amazon Prime Video. Amazon Prime introduced adverts.

But I suppose expecting ad-free video streaming 'just because I paid for it' is also entitled and childish, because to people who use those things as putdowns, everything other people want, is. It's like "everything I don't like is woke" in that sense.

>I can't reveal any details but it was a lot more than just a given storage point

Sorry, not brain not really clicking tonight and used lazy imprecise terminology here, been a long one. But what I meant by "store point" was any single data repository that can be interacted with as a unit, regardless of implementation details, that's part of a holistic data storage strategy. So in this case the entirety of IBM would be a "storage point", and then your own self-hosted system would be another, and if you also had data replicated to AWS etc those would be others. IBM (or any other cloud storage provider operating in this role) effectively might as well simply be another hard drive. A very big, complex and pricey magic hard drive that can scale its own storage and performance on demand granted, but still a "hard drive".

And hard drives fail, and that's ok. Regardless of the internal details of how the IBM-HDD ended up failing, the only way it'd affect the overall data is if that failure happened simultaneously with enough other failures at local-HDD and AWD-HDD and rsync.net-HDD and GC-HDD etc etc that it exceeded available parity to rebuild. If these are all mirrors, then only simultaneous failure of every single last one of them would do it. It's fine for every single last one of them to fail... just separately, with enough of a time delta between each one that the data can be rebuilt on another.

>If you can't do the job you should get out of the kitchen.

Isn't that precisely what bringing in external entities as part of your infrastructure strategy is? You're not cooking in their kitchen.

> just requires candor: I need some me time. I wasn’t feeling up to it. Will catch you next time.

Great! You tell them honestly, what could possibly go wrong. I'm sure nobody's feelings would be hurt when you tell them you weren't feeling like meeting them.

Now next time you drop by and still don't manage to catch them for whatever reason. Now your prior "candor" becomes a lie -- one that never needed to arise in the first place.

Maybe you enjoy getting yourself into these kinds of situations, but hopefully you can understand why others might not.

Someday, theoretically, maybe. This means that, as far as everyone knows, if I properly secure a message to you using RSA, no one else is reading the message. Maybe in 50 years they can, but, well, that's in 50 years. Alarmists would have you believe it'll happen in three. I'm just an Internet rando, but my money's on it being closer to 50. Regardless though, it's not today.

> When multiple people respond to the same email, the email "thread" branches out into a tree. If the tree branches out multiple times, keeping track of all the replies gets messy

I think this is mostly due to bad UIs in email clients. Usenet had similar, if not more extensive, branching many Usenet clients made this quite manageable. I don't see why similar clients could not be written for email.

I don’t understand this sentiment at all. They didn’t sacrifice their balcony, and this is electricity that the central utility organizations couldn’t generate. Many parts of the world don’t even allow this kind of solar panel to be used by individuals, so its legality is actually a policy success.

Generally, balcony panels are hung off the side of the railing, so no space was lost. If this was blocking out windows or reducing the enjoyment of apartments then I could understand, but this basically unlocks “free” solar panel real estate in apartments, without any real installation costs.

Meanwhile, decentralized power generation with all these liminal spaces is basically impossible for a utility company. Hundreds of dollars/euros is not trivial, but spread across years of usage, it’s a pretty affordable way to reduce power consumption, and it’s well within affordable range for the median German household. Plus it’s subsidized! This basically lowers the cost for the utility to create locally generated renewable power, reducing demand over the expensive to maintain public infrastructure.

Being able to plug a solar panel into a spare wall outlet and reduce your bill and grid power usage is so easy, anyone can do this. This isn’t allowed in most of the United States, for example, because central authorities banned it due to outdated safety rules. Many areas with this banned have far more sunlight than Germany (eg California), so far more incentive for the population to want it.

Dieter Rams' style of industrial design has just dominated influencing electronic product design. More expressive industrial design at large isn't dead. Even in the electronics adjacent spaces you have boutique companies making interesting industrial designs for things like synths or computer keyboards.

Though I think there's another perspective to entertain here that isn't just about the industrial design style of the phone or display. Instead, think about how many discrete products general computing devices have subsumed. The disappointment comes across to me less that a slab is consumer computers dominate form, it's that the slab has made the rest of environment more sparse and now a slab is the sole focus point.

If you and I are in the same class of the same fund we would have the same allocation. However if you are in Vanguard Retirement 2050 and I am in Fidelity Retirement 2050 we likely would not. Also possibly if I am in the Admiral Class shares of Retirement 2050 and you are in the Retail Class.

Thanks for disclosing your use of GenAI, that kind of transparency is nice to see up front. On that note though, I took a random example (`calc.rs`) and noticed there was no unit or integration testing validating the parsers or etc. did what was expected of them, or that the end results were correct. Are tests for these tools planned? I get sketched out a bit when I see GenAI code with no automated validations, but I really want to like this tool because it fills such an interesting niche :)

Just so I understand correctly, you mean that with DWDM 2 strands of cables were equivalent to 8 since DWDM as a multiplexing technology increased the capacity of each fiber, right?

> How much is a 10 year old GPU worth? Where is the “dwdm but for GPUs?”.

From other sources cited in TFA it seems GPUs won't last 3 years, let alone 10! But I think we know what the "DWDM for GPUs" is -- it's the processing efficiency gains that we've seen over the last few years which keeps driving the per-token prices sharply down.

"No, arguing against cherry-picking does not mean you endorse everything."

How so? Either you cherry-pick or you take it all. Those are the only two possibilities, aside from ignoring the whole thing. Pretty sure he's not ignoring the whole thing.

How is it ignorant to see that he thinks that the omnipotent and omniscient creator of the universe has written down "perfect laws" for us to follow, and that we shouldn't pick and choose which ones we follow, and conclude that he thinks we should follow all of them?

He may have welcomed gay people into his movement but just based on your clip he doesn't seem to love and support them. He says straight out that he doesn't approve of the lifestyle.

I agree that there's a contradiction between "God says we're supposed to kill them" and him standing there chatting with that guy and not trying to rally the crowd to murder him. But I don't see why we have to resolve that in the "he actually loved gay people" direction. If he says "God's perfect law" demands killing gay people, I'm inclined to believe that's what he thinks. He'd hardly be the first religious person who believes their religion demands X and actually does Y when confronted with the situation in reality. It's great that he can stand there and engage in a dialog with someone he believes his God says should be killed, but that doesn't absolve him from that belief or from professing it.

Wouldn't you expect the conservatives, then, to be the ones who say that violence is justified?

Yet you're seeing the opposite — after the killing of a conservative, it's the left that says violence is justified.

Furthermore, this trend on the left had been building for a while, which we see in surveys done before his killing:

This course really brings formal methods to life! From Coq proofs to real-world blockchain verification, it truly brings mathematical theorems beyond the confines of the paper. I particularly like the concept of "semantic ledgers"—it bridges abstract mathematics with concrete trust, which is exactly the bridge academia needs most. Theoretically rigorous yet practical—this is what computer science should be!

This is one possibility I'm assuming as well. It largely depends on how long this bubble lasts. At the current growth rate it will be unsustainable before many very large DCs can be built so it's possible the impact may not be as severe as the telecom crash.

Another possibility is that new breakthroughs significantly reduce computational needs, efficiency significantly improves, or some similar improvements that reduce DC demand.

You're right that there are a ton of trails, parks, etc. in Connecticut. Which is why I find dashboard lacking (and I admit I have not been on a CT trail, um, ever, even though I spent 20-ish years living there).

There are trails in state parks (think Kent Falls and Sleeping Giant, for instance). And there are also a lot of maps, interactive whatevers, such as https://ctwoodlands.org/explore-trails/interactive-map/ and Rails to Trail https://www.depdata.ct.gov/maps/ctrailtrail/index.html.

Someone else mentioned how fab it is that the state has done this. But it's unclear to me if the state did this or the University of Connecticut did this. Yes, UConn is the state, but UConn does not manage the open data portal for the state (ct.gov). As someone who worked on open data (and i use "worked on" VERY loosely) in the District of Columbia, I would expect the state (ct.gov) to manage the data and the front end. This is not the case.

Finally, while I want to push back about the portrayal of northeastern CT, I cannot. It was a great place to grow up, close and far.

I have sympathy for those affected but this article is disingenuous. I speak Spanish and have just gone to 3 or 4 Spanish news sites, and passed their articles through to ChatGPT to translate "faithfully and literally, maintaining everything including the original tone."

First it gave a "verbatim, literal English translation" and then asked me if I would like "a version that reads naturally in English (but still faithful to the tone and details), or do you want to keep this purely literal one?"

Honestly, the English translation was perfect. I know Spanish, I knew the topic of the article and had read about it in the NYTimes and other English sources, and I am a native English speaker. It's sad, but you can't put the toothpaste back in the tube. LLMs can translate well, and the article saying otherwise is just not being intellectually honest.

My theory is that stuff like this converges on the most economic and market-accepted form factor over time. Look at airliners over the last half of the 20th century - you had all kinds of weird and interesting designs (727, CV990, L-1011, Concorde). Now you invariably have a tube with two engines hung off the wings. Yawn.

It’s obvious that if you’re specifically designing a clean sheet ISA, you wouldn’t choose to copy an existing ISA that has seen several decades of backwards compatible accumulated instructions (i.e. x86), but would rather opt for a clean sheet design.

That says nothing about whether you should opt for something that is more similar in nature to classic RISC or classic CISC.

I have almost 10% of that in my closet RAID5'd with large part of it backing up constantly to Backblaze for 10$/month, running on 10 year old hardware, with basically only the hard drives having any value ... Used a case made of cardboard till I wanted to improve the cooling, and got a used Fractal Design case for 20€.

_Only_ the kind of combination of incompetence and bad politics here can lead to the kind of % of how much data has been lost here, given the policy was to only save stuff on that "G-drive" and avoid local copies. The "G-drive" they intentionally did not back up because they couldn't figure out a solution to at least store a backup across the street ...

Is it discouraged so hard that you can't get it at all? I'd think it would be pretty hard to keep people from importing solar panels from Vietnam or Thailand—although of course you'd probably have to put it somewhere that surveillance drones could see it, if you want it to get any sun. (In that case, if you have a rooftop, maybe you could put it under a frosted-glass skylight.)

If anything, I'd expect the prices to be lower. Do you have a local Indonesian equivalent of eBay like we do here in Argentina? Or, just eBay?

I assume "electricity capacity of 900W" means that the wires from the transformer (and in the walls) are only rated for 4 amps at 230VAC. This means that you can't really run a 2000-watt air conditioner at all. Whereas, with an 800-watt solar panel charging a battery, you can run a 2000-watt air conditioner 40% of the time when the panel is in full sun. Washing machines and refrigerators are an even bigger difference, since they usually have huge peaks of current draw when they start up their motors, but relatively low average power. So the solar panels may actually be a much bigger boon than simply comparing 800 to 900 makes it sound like. A single car battery can typically source 6000 watts for brief periods of time.

I've been playing around with this for a few weeks. Newton is a pretty thin wrapper around mujoco-warp, which is trying to port mujoco, originally a CPU sim, over to warp on the GPU. There is also mujoco-mjx for this purpose, but using jax instead of warp. I think mjx/jax has the edge on performance because there are mature RL libraries for jax (brax) and big advantages to using Jax for everything, especially with its ability to "vmap" over each layer of abstraction. But I can see why nvidia wants to move away from IsaacLab using physX+pytorch because physX was made for games and interfacing with it through IsaacSim is a bit of a kludge. And apparently mjx isn't so accurate with collisions because of the way it has to be treated in jax. Pytorch RL works decently with newton/warp, at least they can share GPU buffers and you don't have to copy things back and forth to the CPU, however you can't optimize with cuda graphs past the newton/warp boundary because newton/warp have their own cuda graph capture scheme going on at the same time underneath.

They already have a newton branch of IsaacLab on github but its pretty early for it. I just came across a dope project today that is a different wrapper around mujoco-warp that already mimics IsaacLab's api and you can run some robot environments on it. Clean code too, very promising: https://github.com/mujocolab/mjlab.git

> We’ve written at Hard Reset before about tech workers leaving long-time employment at companies like Oracle and Cisco, driven away by their employers’ blind corporate advocacy of Israel and retaliation against any form of pro-Palestine activism. One former Oracle employee told us that she is leaving tech and the idea of “girl-bossing” altogether, instead traveling around in a camper van and buying a vineyard in Porto, Portugal

If you can afford to buy a vineyard in Portugal, then you didn’t leave tech out of protest over Middle East politics, you retired because you’re rich. Which is fine, but don’t try to make it about Israel.

Well, this is sure to come up on next week's (well, later this week) Accidental Tech Podcast. John Siracusa (one of the hosts) used to write those twenty page reviews of each major release of MacOS on ArsTechnica. He and I both miss the spatial Finder. I'll try this out tomorrow for sure. If I wasn't worn out from a busy weekend, I'd try it now. I can't wait to see how this holds up.

OP: whether this delivers or not, it's a concept that concerns me. Thanks for caring about this and doing something about it.

Curious: is anti-islanding an actual feature, or a necessary behavior of any power source that adds power to the grid? I can't imagine how a second power source would work at all if it weren't syncing to the main source's AC phase. So it seems that if you implement the syncing, you get anti-islanding for free (assuming you handle the case of a missing main source phase by not providing power at all).

This is a newbie question, and I look forward to learning how it's more complex than this.

I would bet that it's far lower now. Inference is expensive we've made extraordinary efficiency gains through techniques like distillation. That said, GPT-5 is a reasoning model, and those are notorious for high token burn. So who knows, it could be a wash. But selective pressures to optimize for scale/growth/revenue/independence from MSFT/etc makes me think that OpenAI is chasing those watt-hours pretty doggedly. So 0.34 is probably high...

...but then Sora came out.
