It's a long weekend over here, so I managed to load up the code, BOM, KiCAD files, production files, and assembly instructions. Also some scope trace images of what the signal should look like at different stages:

https://github.com/seanboyce/TRNG

I didn't specifically design this for other people to easily replicate, but should not be too hard with some solder paste and a hot air rework station.

The assembly code is extensively commented-- I realize AVR assembly is not most people's native dialect, haha.

I hope you enjoy!

Hi I am also doing the same thing but with OpenRouter(model provider) and a database on AWS through a Lambda Function!

Now I'm finding a way to plug the bot into Insta, Whatsapp and Facebook. I was thinking of directly plugging into Meta but I see everyone mentioning ManyChat. Im quite new to this so can I ask why do people use a third party like ManyChat instead of directly using Meta?

I am thinking outside blackboard ones, where owners write message in chalk [0] - they don't pay anyone to write the words, nor do they pay anyone to "install" it (= take it out).

I suppose the sign itself must be paid for... but many eateries are using the same signs for menus, so if owner re-purposed one of the menu signs, is there money involved? Or does owner have to dig in garbage bins to find the blackboard for free? What about writing messages straight on the wall? What about printing signs on the printer your own and taping them to the wall?

Now, don't get me wrong, I think it would be an overall improvement if those professionally-made outdoor signs get replaced by artisanal handwritten (or at least handmade) ones, but I don't think that this is what the original idea was about.

Of course most married people considering a job offer would discuss it, but that doesn't mean the person making the claim isn't actually just using a delaying tactic.

(For example, maybe they already discussed it with their spouse. Or they're going to discuss it in the next hour, but they are saying this when their goal is to effectively delay for a week.)

That's just one example of commonplace lying.

A lot of people will openly lie, and think that's normal. Even most of these advice articles for job-hunting are full of habitual corporate-standard lying.

But not all people are like that, and don't want to hire corporate-standard liars.

It's actually the simplest scheme. Reparse from the top whenever you need to query a setting. When you see one, exit. No need to even bother to store an intermediate representation. No idea if this matches the actual ssh implementation, but that's the way many historical parsers worked. The idea of cooking your text file on disk (into precious RAM!) is fairly modern.

>A difference without distinction. From the financial point of view, the cheque goes from the Government of Canada to the dealership. Whether the dealership then cuts another cheque or simply discounts the vehicle $5000 is irrelevant because in either case the money has to enter the dealership's coffers.

It's a huge difference. Dealerships cannot just make a claim and collect the money. It's not theirs, even though they collect it.

So the article contains the data for the detected concentration. And it's basically a nothingburger.

For example, the samples contained 37 to 80 micrograms per liter of cadmium. The safety limit for _drinking_ _water_ is 5 micrograms. So diluting the retardant with 10 times the water makes it safe enough to drink.

Lead content in the samples was wildly different, from 7 micrograms to 800, indicating that the sampling procedure itself was unreliable.

Similar story for chromium, 100 micrograms is the safe level, and 200-300 micrograms were in the tested samples.

In fact, only arsenic is concerning, with roughly 10-60 times the allowed concentration for the drinking water.

Do you always answer the door for Jehovah's Witnesses, alternative gas companies, or posters? Usually, people put "No soliciting" signs on their doors and in their yard. They get irritated, if not irate, when these people ring the doorbell. How is advertising any different? Would you invite these people into your home to watch TV with you, eat dinner or drive around town?

I see it as a privacy issue.

Those quotes are from three different sources. Which of those would you consider “bullshit” and why?

If the Tesla vandals deserve to be in a lunatic asylum or charged with hate speech, fine. Go through the legal process to prove it in court. But to suggest that they deserve to be sent to a foreign black site for a lifetime of torture is simply unhuman.

Well said; I can delete my (later) sibling comment!

> Molting is one of the features that makes difficult for arthropods to reach great sizes

Also, chitin becomes too heavy. Somehow, it's connected to body mass increasing as the cube of length, but I don't remember exactly how. Maybe the chitin legs would have to be too strong.

> their skeleton and tegument cannot grow between moltings

To clarify an essential aspect: because their rigid exoskeleton can't grow, they must shed and replace it for their body to grow.

> Late last year, LAist requested samples of MVP-Fx from Cal Fire, the U.S. Forest Service and Perimeter Solutions, which manufactures the product, for the purpose of running an independent analysis for heavy metals. All declined.

How is this legal? Like how can the government spray random chemicals all over the land and there's no way for the public to compel them or the people supplying them to declare what's in them?

I use tesseract which uses a LTSM OCR along with multimodal LLMs to converge to a ground truth. It works remarkably well. However for my purposes I don’t want a LLM explaining charts I want it to produce a vector format of the chart. There are a few models that produce Latex chart formats I’m experimenting with:

https://arxiv.org/pdf/2405.15306

Most OCR pipelines like this, along with excellent commercial ones like doctly.ai, are focused on OCR for LLM consumption - while I’d like to be able to recreate the original scientific work that predates digital typesetting in modern typeset - for yes LLM but also to preserve and promote science of yore, much of which includes discoveries forgotten but relevant still to problems we face today.

I live in a pretty sleepy farm type area, with a growing town in the middle. There are most of the main restaurant attractions. My wife and I are always amazed as we drive by the back to back Chili's, Outback and Texas RoadHouse., that are bustling at the seams, the parking lots are very often overflowing. We are amazed that there still are apparently plenty of people who can frequent these places.

So i can fully imagine that this article has it right, i just don't see it where i live.

Agree, that'd totally work - things like "billboards" or "ads on public transport" are possible to define and regulate. Advertising on the web would be much harder, I'd like to hear a good proposed rule on that.

Sadly, a post titled "A proposal to restrict certain forms of advertizing", and full of boring rules will be much less likely to get 800+ points on HN.

They are talking about PFAS, which was (is?) in aqueous foam firefighting chemicals that were (are?) in widespread use.

At air force bases, airports (both the trucks and hangar suppression systems), firefighter training facilities. Municipal fire departments have metering devices on their trucks and can mix in the foam additive if it's warranted. Foam is incredibly effective on a lot of fires.

It gets into the groundwater from stuff like accidental hangar fire suppression system triggering, training exercises (at an airport near me, they have a dedicated steel structure that vaguely resembles a jetliner which they use for training, and yes, they use foam every time.) There are a lot of videos on youtube of the systems going off, intentionally (certification after installation - the system has to fill the hangar to X feet of foam within Y time), or accidentally being triggered because someone didn't respond to the prealarm fast enough to get to the control panel and stop it before the system started discharging.

At AF bases, FF training facilities, and airports it gets into the groundwater and it's game over - everyone who gets water from that water table has to install an expensive filtration system. And that's assuming it doesn't get into a nearby river or stream. The stuff gets used on a lot of vehicle fires on highways, those are often near riviers, streams, lakes, reservoirs....

I hadn't heard that PFAS or related chemicals were in the colored flame retardant used in forest fire fighting, though.

Actually, I'm wrong.

AMD's deep dive [1] says register use is low during BVH traversal, so they are still using shared memory for the stack. According to the ISA doc [2] they have a special mode for the stack that overwrites older entries instead of overflowing and a fallback stackless mode.

So the register allocation is actually increased when invoking the hit shader, allowing each hit shader to use a different number of VGPRs, spinning is probably the most logical approach. They probably don't even need the deadlock avoidance mode with their current implementation, which seems to allocate the full set of registers when calling the hit shader and only free them at the end.

This presumes that Apple brought in Jobs as a decision maker, and NeXTSTEP was attached baggage. At the time, the reverse was true - Apple purchased NeXTSTEP as their future OS, and Jobs came along for the ride. Given the disaster that was Apple's OS initiatives in the 90s, I doubt the Apple board would have bought into a Linux adventure.

see now this is where I could totally use a recommendation. I dont know what a capacitor is, what a resistor is or what ohm's law is. I would expect there is atleast one book out there that can teach even an absolutely noob like me how to build a microcontroller circuit board from scratch. I mean not on page 1 obviously but maybe on page 1037?

What were America's political objectives in those wars? There are stated and unstated objectives. We don't really know if they were achieved or not. Maybe Iraq was a Haliburton enrichment play... That's still going on [0]!

But you're not really right here. In both cases, American forces dismantled the initial enemy: the Taliban regime fell in 2001, and Saddam Hussein’s government collapsed in 2003. Combat superiority wasn’t the issue.

We "lost" because all of those wars were occupations. Locals just didn't care enough to keep us there, or vehemently opposed American presence. It's really, really hard to occupy a country that doesn't want you there, even if your military capacity is vastly superior.

Defending a nation like Taiwan or Japan is a totally different story. If you are defending a country from an external threat, they want you to stay.

I was responding to the above commenter, who wrote:

> Living in fantasy land is how the richest nation the world has ever seen could lose a war to teenagers in Afghanistan.

What I'm pointing out is that the US has extreme combat superiority that no country has ever had to reckon with. And we have never waged "total war".

Did anyone try the setting for "when laptop lid closes" set to "do nothing"? I've always used that on a half dozen Windows laptops over the years and never seen it not work. Even if sleep is finicky, that will just make it stay fully running. If you want it to sleep, do that separately from the start menu or whatever, don't tie the sleep state to the lid state.

It started off as me just trying to solve a personal problem, but you're right, I've considered that direction. However, I'm staying focused on the candidate side since I still have a lot of ideas I want to explore there first.

1. Republicans knew what states would do, so actually yes, they do bear responsibility for positioning them to do it.

2. Surely we can agree that Republican state lawmakers are responsible for the laws they make? Surely we can agree that voters who voted for Republicans who openly said they are going to ban abortion without exception, are responsible when the lawmakers they voted for do exactly what they voted for them based on? Are you just going to pretend that these people aren't responsible for literally their own actions?

One of my favorite books by my favorite author. Tracy Kidder gets to the heart of everyone he profiles like no other. Strongly recommend his book House if you like Soul of a New Machine.

Funny anecdote: I've read Soul of a new machine many times over the years, and love it dearly. I stayed with my aunt and uncle last year and somehow the topic of mini computers came up. I mentioned Soul of a New Machine and my uncle said "oh yeah I worked on that computer." I was blown away. Apparently he had worked at Data General and he was on the software team (which is briefly mentioned towards the end of the book) that wrote the software the Eagle was released with.

Live in the present, with your consciousness externalized momentarily but without any effort; when the mind stops linking itself to the past and to the future, it becomes no-­mind. If from moment to moment your mind dwells on what is and drops it effortlessly at once [just before moving on to something else], the mind becomes no-­mind, full of purity.

Except for a some of the population of white countries right now, almost everyone in existence now and throughout the history of our species is and has been extraordinary more conservative—and racist—than western progressives. Even in white countries, progressivism being ascendant is a new trend after decades of propaganda and progressives controlling academia/entertainment/"news".

It genuinely boggles my mind that white progressives in the west think the rest of the world is like them.

I've written some things about home monitoring/automation before (see: https://blog.kroy.io/2017/12/19/monitoring-home-power-consum...)

After Acurite shennanigans finally broke my setup, I wrote an MQTT ingest module for weewx, because I couldn't find one that worked.

With some fairly boilerplate ESP32 code, it's trivial to hook up whatever sensor you want.

I tried to keep it generic as possible. Cheers.

> “You are not the first person to ask for us to give them fire retardant. It happens. It’s not something we do.”

Scary to think what other discoveries were missed if those other investigations had been given the samples they asked for.

I also enjoy how they all pile on to say the results can't be trusted.

> Cal Fire, the U.S. Forest Service and Perimeter Solutions all dismissed the results of the testing — saying that the samples couldn’t be relied on because they were gathered in the field.

It’s funny, I switched from engineering to management a few years ago, and as part of learning to be a manager I really had to learn to negotiate (Avery Pennarun, founder of Tailscale, describes Eng managers as professional negotiators, which I think is at least partly true). I loved this article.

There’s a book on negotiation called “Getting to Yes” that uses a different framework, which became my preferred way to think about negotiation: The goal of a negotiation is to strike an agreement that both parties are happy about. The stereotypical negotiation, “I won’t go a cent below $10,” “well I won’t go a cent above $8” is bad negotiation because even if they meet at $9, neither is happy about it. Instead, the effective negotiator thinks creatively about what would make them happy and asks if it’s available.

As much as I basically agree with it, I would cast the advice in this article differently. Here’s my take, for what it’s worth:

- Re. all the author’s advice about withholding information: you may not be happy if one day you find out that you’re being paid 30% below market (though maybe you won’t care—know what you care about! It will help you negotiate more effectively). The ideal solution here, though, is to know about the market! Consult levels.fyi, talk to your friends, maybe interview from time to time before you’re really looking.

- Re. Don’t be the decision-maker: this is a useful rhetorical tactic, often also called “bad cop,” and it’s not really negotiation-specific but you can bring it into a negotiation if it helps you (at one startup, our co-founder would say on sales calls, “let me check with my sales team” when he was definitely the whole sales team). Honestly, IMO it’s only really useful if you’re trying to placate someone, which you hopefully shouldn’t be when you’re weighing their offer, but you’re welcome to use it if you have social anxiety about pissing off the recruiter (you probably won’t, but I understand the worry)

- Re. stay positive: …yes? The goal is to get to a deal you’re both happy with. If you’re already not happy, then the negotiation is already over. The effective negotiator walks away before getting mad—why burn a bridge over one deal not panning out?

- Have alternatives: honestly this is the main thing. I don’t know how much there is to say but anyone will understand you not being happy with a deal that’s already not your best option.

First off, water standards were weak in the first place (because of lobbying from the chemical industry) and have been weakened several times since, so they've become a joke. If you're over the federal limits, you're in pretty bad territory.

It's also not a "nothingburger." How much area do you think one liter covers in ground area? Now go look at the giant cargo planes dropping the stuff thousands of pounds at a time?

All that crap washes down into waterways or leeches into the soil, then into the water table.

> Lead content in the samples was wildly different, from 7 micrograms to 800, indicating that the sampling procedure itself was unreliable.

...that's not what that indicates, no. It could also be that lead is very inconsistently spread through the chemical.

Chromium doesn't have a safe level, just like there's no such thing as a safe level of radiation.

Before you start hammering away that the chances to you or me are extremely low: so are house fires, murder, etc. They still happen, and they happen to somebody. A low concentration of chromium consumed by a large population will definitely cause health impacts.

Can you provide some citations / documentation of your claims about "no effect"?

As a non-EU / non-UK reader I went searching for more detailed analysis after reading your post. The first detailed analysis I found was the UK Office for Budget Responsibility's Brexit Analysis. [1]

The OBR's analysis suggests outcomes like the following (all quoted from that assessment) that seem to suggest some degree of negative economic impact:

* The post-Brexit trading relationship between the UK and EU, as set out in the ‘Trade and Cooperation Agreement’ (TCA) that came into effect on 1 January 2021, will reduce long-run productivity by 4 per cent relative to remaining in the EU.

* Both exports and imports will be around 15 per cent lower in the long run than if the UK had remained in the EU.

I didn't think that was confusing, your article pointed it out fine and clearly. However it doesn't address my point. "(Un)intentional" is solely a qualifier regarding the intentionality behind becoming a moderate, not the "moderate" part itself, which is what I'm arguing against. Independent thought doesn't necessarily lead to a moderate position. It leads to a position that almost certainly isn't perfectly aligned with a single -ism ideology. In fact, many of the individual beliefs held may well be considered the opposite, "extreme" in the sense of the Overton window (which is what "moderate" is really about).

One of my favorite virtual keyboards was a linear swipe keyboard called something like “Minimum” (minus some vowels). The QWERTY keys were laid out horizontally like a piano keyboard. Text input was fast and surprisingly accurate.

This was about 15 years ago, but then the app and company disappeared. I can’t find any trace of the keyboard or company on the web today. Perhaps they were sunk by some patent issues.

I derive substantial portions of my wealth-building from the military-industrial complex, while living outside of the US insulates me, and my children, from the worst of both America's fractured society AND from the authoritarian overreach that typically disproportionately affects minorities such as myself.

For my family unit, the path through all this chaos of imperial decline involves building up sustainable property ownership and revenue streams in Asia and Africa while winding down our US footprint to a minimum (real estate, social security/military pension/VA benefits).

For me to engage in an insurgency, the government would need to seize our US home, and/or cancel our benefits. Even then I'd need to work out some cost-benefit analysis to determine whether I could maximize my children's wealth by either a) continuing to build wealth outside the US or b) fighting to gain restitution via the new revolutionary government.
