They're so nice for prototyping ideas and not becoming attached to the code due to sunken cost. I was playing around with generating intelligent diffs for changelogs for a game. I wasn't sure what approach to highlighting changes I wanted to take without being able to see the results.

Prior to vibe-coding, it would've been an arduous enough task that I would've done one implementation, looked at the time it took me and the output, and decided it was probably good enough. With vibe-coding, I was able to prototype three different approaches which required some heavy lifting that I really didn't want to logic out myself and get a feel for if any of the results were more compelling than others. Then I felt fine throwing away a couple of approaches because I only spent a handful of minutes getting them working rather than a couple of hours.

There are many people that believe the contrails, that they refer to as chemtrails, are about weather control. Those are the people that I think are confused. Just search "chemtrails weather control" or "manipulation". I have also spoken to many people that hold this belief.

Also, read the wikipedia on chemtrails: https://en.wikipedia.org/wiki/Chemtrail_conspiracy_theory

Ithink there are also 2 factors to this.

1. Learning curve: Just like any skill there is a learning curve on how to get high quality output from an LLM.

2. The change in capabilities since recent papers were authored. I started intensively using the agentic coding tools in May. I had dabbled with them before that, but the Claude 3.7 release really changed the value proposition. Since May with the various Claude 4, 4.1 and 4.5 (and GPT-5) the utility of the agentic tools has exploded. You basically have to discard any utility measure before that inflection point, it just isn't super informative.

The answer to this question is wrong:

> Why don't we just make IP networks without Ethernet?

The article implies that we need MACs, and of course we don't, and lots of protocols exist that don't use ethernet framing. SLIP and PPP only speak IPv4, for example.

Also the real reason behind the "why" is more boring than the blog implies. Ethernet predates IP. It's a simple (almost the simplest possible) protocol for a bunch of hosts to share a single network without running into trouble talking to each other. And it decided on a hardware-unique "MAC" as its way of doing addressing.

It was simple, so it was cheap. So everyone built out cheap ethernet hardware. And when it arrived, everyone wanted to run IP on their cheap ethernets.

It's disheartening if you do care about long-term issues, but perhaps these are all long-term issues.

In a way, I think people tend to fight for causes they are exposed to and think their voices are on the right side of History. I'm appalled that Belgians are out protesting for Gaza (which is also important) but don't care one iota for what 3M did to half the ground water of the country — and how Belgian politicians and the EPP looked the other way. We're being slowly poisoned over here, but it's the war over there, you have nothing to do with, that matters the most. Right.

We are facing the dismantling of social protections, climate change, corrupt governments, and so on, perhaps people pick the one issue that feels remote enough yet meaningful to fight for.

But someone has to care about Gaza as well, I suppose. It would be far more useful to their lives if people fought for local causes.

In Canada, OpenMedia is one org, https://action.openmedia.org/page/177914/action/ | https://action.openmedia.org/page/73972/donate/

When Bill C-26 was introduced, OpenMedia and our partners in civil society.. unpacked what the bill meant for Canadians, raised the alarm about its risks, and put forward practical recommendations to improve cybersecurity without compromising privacy. Civil liberties groups, academics, and experts joined us in calling for change. While a few of our fixes were adopted, most were ignored. Those unfinished issues now carry over into Bill C-8.. This campaign is about restarting the national conversation on cybersecurity and privacy. If we push harder this time, we can shape Bill C-8 into the law Canadians want and deserve.

> The money's just moving around and around

There's nVidia that we know (primarily graphics cards) and more like an investment firm "nVidia" these days. The stocks have grown so much that they are trying to turn their fortunes around (to sustain growth) by investing everywhere.

nVidia has invested in so many companies in the ecosystem and beyond.

The consequence described by the National Post here is a clearly plausible consequence of a plain reading of the legal text presented.

Advocates have been warning about this bill (and previous iterations and attempts at the same theme) for a long time. It's being opposed by all sorts of people, certainly not all Conservative party supporters, as is readily apparent with an appropriate Internet search. See for example https://ccla.org/privacy/fix-dangerous-flaws-in-federal-cybe... from the Canadian Civil Liberties Association, and https://sencanada.ca/Content/Sen/Committee/441/SECD/briefs/2... their submission to the government regarding the previous attempt at the same thing.

Your criticisms have some validity, but email is in a sense objectively great in that it's the thing that "won."

I believe there's a universe of difference between ONE provider and a few megacorps plus weirdos like me who pay for my own domain; I actually think that would ALSO be a good model for twitter-esque microblogging the way it pretty much works for email.

> ..who were given far too much leeway to start with.

Listen to your language. Freedom of speech and freedom of peaceful protest are now far too much leeway? The very rights protected by the Charter? Because they are protesting against things you like? Or protesting for things you don't like? Your like and dislike trumps their freedom does it?

You do realize who you sound like, don't you? Think about it. Mull it over carefully in your mind. Your rhetoric is dangerously close to a well-known Sozialisticher party.

Level 1, yes, this is the correct way of thinking. You should always take the highest scoring move.

However, Level 2, making a decision harder for your opponent, might force them to spent more time thinking about the decision. If for some reason there is an imbalance of pondering, this might be beneficial. Suppose that you knew X position would be reached before your opponent, so you had more time to study it, you know what the correct piece to take is, whether a promoted rook, or a previously existing rook, but your opponent doesn't yet, and crowning to a queen will force your opponent into a move without a thought.

The computer will sometimes do this, more because of randomness than strategy, but it is probably always the case that if they underpromote, you should take, it's like a tell of theirs. Perhaps there is a case for nash equilibirum where you must sometimes offer an underpromotion in a scenario where a queen would have been marginally better such that underpromoting doesn't signal to your opponent that they should take the piece (whichever it may be, I'm a bit dizzy)

Very theoretical, but not impossible that underpromoting in such scenarios might be beneficial, that said, very theoretical.

Even having a Gmail address doesn't make you immune from someone putting in the wrong address.

I made a throwaway/spam account with a silly name back in ~2007, and then in ~2015 someone established a fairly successful company with that name. I now regularly get job applications, tax documents, and employee timesheets to my email. They even signed up for the service that controls their website with my email.

I keep waiting for them to contact me about taking over the address, but as far as I can tell they don't even realize they don't control it.

It is surprisingly hard to find reliable figures. Best I could do was a global solar installation of 2-3 TW and global BESS of around 200 GW/500 GWh right now.

China is leading in both, but I'm more interested in local BESS and other storage deployments locally in northern Europe. I think for example Spain started getting more heavily involved only after their massive blackout. According to those links there is a very large overcapacity in battery production, but I don't see it reflected here. I'm sure it will happen at some point though.

Some of thr language features like operators can be overloaded using method tables, much like python's double underscore methods. I do think that the inability to do this in JS is what held it back from becoming a data processing powerhouse. But it perhaps can be made to run fast precisely because of the lack of such overrides (otherwise we'll be running python at JS speeds). That said, LuaJIT seems like a good compromise and might be best of both worlds.

The MAC address is meaningful only for a single link. It doesn't get copied through routers and get carried along to the destination. (At least in theory. Between software defined network hardware and enterprise WiFi, there are cases where MAC addresses have wider scope. But they rarely leave an organization.)

The Xerox plan for Ethernet was to use XNS, with a 32-bit network ID and a 48-bit MAC. Routers only had to know how to find a network ID, and once the packet hit the correct destination network, the MAC address routed it to the destination.

Early on, there was a thing for "multi-protocol routers", that forwarded XNS, DECnet, IP, and a few other things such as Parc Universal Protocol, PUP. Cisco was once big on this, because Cisco came out of Stanford, which had a few of everything and tried to interconnect them. In the 1990s, most of those branded protocols died out, although as late as Windows 2000, Microsoft still supported TP4, a bad idea from circuit-oriented telco people. There was a telco approach to networking, where you dialed up a reliable circuit to your destination, transmitted what you had to send, and later got a bill for the call. This, fortunately, lost out to IP.

(I had real doubts about pure datagram long distance networks. We didn't know how to deal with congestion in the middle of a pure datagram network. We still don't, but cheap fiber saved us from having to.)

There was a really good section of the article that went into great detail of the math and how it would easily outweigh the CO2. How it would only require something like diverting 2% of all flights as it is only that percentage of flights that make the majority of the contrails and that the diversion of the average flight would be something small like an extra 2 minutes flight time for shorter flights and like 6 minutes on a longer flight which the article states is not much increase in fuel consumption as well as not such a time increase to dissatisfy customers. So if the article is accurate in their math then the associated costs in all three fuel, CO2, and time are not an issue.

> There are, of course, a few caveats and a contrivance. Stick with me for Part Two and I will explain, including to give directions so that you can play too (with suitable hardware or emulators).

This article is 3-4 years old - any hint of Part 2? I'm assuming those nested copies of 3.1 are stuck in Standard Mode.

In modern society it's pretty much impossible to live without using the internet. You can't apply for a job, you can't apply for a rental. You can't even order a burger at some restaurants without scanning the QR code.

Anyone too dangerous to be allowed any access to the internet probably just needs to be in jail. What would be the point in leaving someone to their own devices while preventing them from participating in society at all?

As a former employee of state and local government, who walked away from both pensions, this was my takeaway.

At the beginning of a project, the government could spend above market for a great architect to lay down the data model and put some patterns in place which could then be reasonably well maintained by below market rate staff, but there are rules and public pressure.

Interestingly, my local govt hired Deloitte to put in a serverless AWS-based application that could have been a simple CRUD app hosted on a medium EC2 instance. It cost $1.5 million and didn’t work, in addition to the hundreds of thousands per year in cloud costs.

Could have been a Django app with Celery. The cost could have been in the low thousands per year.

It could even have been done with a succinct AWS serverless system.

But that’s not the schmooze that can impress high level stakeholders, themselves less familiar with good design patterns, and win the contract.

Always was.

It's why I found it so dismaying when we went through years of apparently serious newspapers reporting on every twitter-storm as if it was important. Yes, it was a good if unreliable source of breaking news, but the general noise of people fighting back and forwards about whatever it was that week ... was just noise, among a relatively small group of motivated crazies. Using it as a societal barometer just results in skewed coverage and an emphasis on American social issues that aren't necessarily as relevant everywhere else.

The whole concept of a country as a related group of people from one ethnicity or historical origin is relatively recent.

Feudalism did not have this concept; a country was the land belonging to a king (or equivalent), mediated through a set of nobles. There was no concept of illegal or legal immigration; the population of a country were the people who worked for, or were owned by, the nobles ruling that country. There were land rights granted to peasants who had historically lived in that place, but these could and were often overruled by nobles.

European nobility had no such idea of ethnicity or national grouping; the English monarchy is a German family, and most of European nobility were related to each other much more closely than to the citizens of their country.

Early post-monarchy states didn't have this concept. The English Civil War and the French Revolution didn't create states that had a defined concept of the citizen as a member of any ethnic grouping. Again, there's no mention of immigration in any of the documents from this period. It just wasn't a concept they thought about.

The whole concept that a nation-state is a formalisation of a historical grouping of ethnically related people is a very recent one, only a couple of hundred years old.

So to answer your question: It is very easy to have a sovereign country without a policy that prevents unfettered immigration; you just don't care about your population being ethnically diverse. Your citizens are the people who live in your country, and have undergone whatever ceremony and formality you decide makes them citizens.

This is, after all, how America historically did this; if you arrived in America and pledged allegiance, you became a citizen of America.

The consequences described by the title are clearly not supported by a plain reading of the legal text by anyone who is remotely familiar with how to read legal text.

Your links don't support the the claim in the title of the national post article. The CCLA is complaining that it would enable the government to make telecoms install backdoors, and otherwise violate privacy rules, not that the government could "strip internet access from specified individuals". I haven't read the bill closely enough to know if I agree with them on that, but a bill having a different issue doesn't justify the false headline by the national post that everyone is discussing here.

(I have not read the contents of the national post article, as it is paywalled. So I can't comment on any other consequences actually described in the article).

That’s narrower than a Boeing 737’s wingspan, and when you look at planes leaving a trail behind them, you can often see the trail fan out much wider than the plane.

Not sure how wide that would be, but the length has to be factored in too, which begs the question, how wide and long is a piece of string/cloud?

On the ground looking up the sense of scale falls apart a bit.

Schema.org metadata (using microdata, RDFa or JSON-LD) is quite common actually, search engines rely on it for "rich" SERP features. With LLMs being able to sanity-check the metadata for basic consistency with the page contents, SEO spam will ultimately be at a disadvantage. It just becomes easier and cheaper to penalize/ignore spam while still rewarding sites that include accurate data.

The schema.org vocab is being actively maintained, the latest major version came out last March w/ the latest minor release in September.

One of my favorite subjects is politics. I enjoy reading books about politics, and keeping up on (geo-)politics, subscribe to political magazines and honestly don’t mind navigating office politics.

Because at the heart of it it’s all the same. It’s humans acting like humans. Every person (and organization) has desires and fears. When two parties get together, balancing everyone’s wants is fun. It’s like a complicated engineering problem, except with people requirements instead, and politics is the architecture.

I think people are rad and genuinely enjoy these kinds of problems.

IP packets and Ethernet frames are separate animals. Ethernet doesn’t know IP, except for a flag saying “interpret my payload as an IP packet”. It doesn’t have src or dst IP addresses. And an IP packet doesn’t know about its physical transport. It doesn’t have src or dst MAC addresses.

You can put other things than IP packets inside Ethernet frames. You can put IP packets into non-Ethernet carriers.

The short version is that small LANs route frames by MAC addresses and don’t know about IP addresses, and the Internet cares only about IP addresses and not MAC addresses.

I'm not going to argue the point, I'm no climate scientist. But Wikipedia https://en.wikipedia.org/wiki/Contrail disagrees with you as well, so you'd need to argue with their sources too.

"In general, aircraft contrails trap outgoing longwave radiation emitted by the Earth and atmosphere more than they reflect incoming solar radiation, resulting in a net increase in radiative forcing."

Shiny bright light goes through or gets scattered. Dull red blackbody radiation gets absorbed. Doesn't sound too counterintuitive to me, but again I'm no expert.

Yes, our goal is to provide a stable, open source platform on top of the cutting-edge AI tools. We can systematically update dependencies as needed and ensure that outputs meet quality requirements.

We also have plans for eval features in the product so that users can measure the quality of changes over time, whether to their own project configs or actual LlamaFarm updates.

Yes, all that's a bit hand-wavy, I know. :-) But we do recognize the problem and have real ideas on solutions. But execution is everything. ;-)

I would say I get more (I've been coding 40+ years). I get pretty good results, I find a lot has to do with crafting your prompts well. I think knowing what the outcome should be, technically, makes a big difference. It's getting less and less where I have to argue with the AI / do it myself. Not to mention the amount of little productivity / quality of life scripts I get it to create. They really smooth out a lot of things. I feel like its more heading towards "solution engineering" rather than coding where I'm getting a lot more time to think about the solution and play with different ideas.
Show HN: RoomYou – A Sensor for Indoor Wellbeing
by jillekuipers | 2025-10-08 03:08:32+00:00
Hi HN! I've been working on the RoomYou, a sensor that monitors indoor environments to promote health and comfort. It measures CO₂, temperature, humidity, atmospheric pressure, and melanopic lux (M-EDI) in real time.

Why Indoor Air Quality Matters Tiny living spaces are increasingly common in urban areas, and I also live in a small, modern apartment in a hot/humid region. I can open my windows or use mechanical fans to ventilate, but without them, the CO₂ level can rise rapidly at night from my breath. Using the sensor helps me to understand CO₂ levels so I can manage it and I will sleep better. Research from Harvard shows that CO₂ levels above 1000 ppm can lead to a 15% drop in cognitive function, while levels above 1400 ppm can result in a 50% decline. I also use the device to manage humidity. When the relative humidity is over 60%, I may feel drowsy, so I use a dehumidifier. When it's below 30%, I use a humidifier to raise it.

The Importance of Light Most of us spend up to 90% of our time indoors. While indoor lighting is often bright enough for visual tasks, it can be too dim to support a healthy circadian cycle. We added M-EDI to the RoomYou to measure circadian-supportive light throughout the day. This is particularly useful for those in older buildings that don't meet newer standards like WELL and BREEAM.

A Professional and Accessible Tool The RoomYou is a helpful tool for many environments, including care centers, offices, schools, and homes. It uses a self-calibrating non-dispersive infrared (NDIR) sensor for CO₂ measurements. The sensor is battery-powered and features an E-Ink screen for clear visibility without the nuisance of a screen glaring a night. Measurements are taken at 5-minute intervals, and you can export the data for analysis. The device helps satisfy the requirements of standards like WELL v2™ and ANSI/ASHRAE 62.1-2022.

An app is also available to save and export data, providing valuable insights and helping to meet reporting needs.

Here are some high-level references for more information: * WHO Housing and Health Guidelines <https://www.who.int/publications/i/item/9789241550376> * EPA Indoor Air Quality <https://www.epa.gov/indoor-air-quality-iaq/inside-story-guid...> * Harvard Healthy Buildings <https://healthybuildings.hsph.harvard.edu>

I would love your feedback on the device, its features, and any potential use cases. And happy to answer any questions!
