PM_me_your_math··on Taking a Radio Camping
A buddy of mine uses one and it is effective. Most of your noise will come from buck converters and other cheap power supplies in the near field. Cell phone chargers, 120ac to 12vdc PSU, computer PSU, and fluorescent lighting ballasts are big culprits. Plasma TVs will generate more noise as they age. Pole-mounted cable repeater PSU go bad and start heating up, generating a shitload of noise. Any arcing on cracked insulators will generate RFI and can be easily located by driving around with a clear AM channel on your car stereo. Report these as they must also be repaired. Cheap solar panel inverters are also noise generators. A process of isolating house circuits helps identify the offending devices if they are in the home. In most cases, it is unlawful for devices to generate spurious emissions. In the case of solar panel inverters, they must fix/replace them if you complain. Another thing to check is cable tv leakage, which is less of a problem today, but can still cause interference. Unterminated cable coax can radiate lots of noise in the 144mhz band, and also on other channels. Great article about RFI hunting and elimination: https://www.arrl.org/files/file/RFI/Thompson%20Noise.pdf
PM_me_your_math··on Can We Engineer Our Way Out of the Climate Crisis?
If the so-called "total collapse" threat was real, then Obama, Gore, DiCaprio and all the other ocean-front mansion owners wouldn't have 1) bought the home or 2) been able to insure it.

So why cripple our economies, ruin our lives, increase our food, transportation, and energy costs? Because of faith? Dire climate-related predictions from the church of climatology date back to the 1960s. Hundreds of them. Not a single one has ever come true. Not one. But we should believe it now?

Catastrophic changes happen over geologic time. There isn't a tax which can stop a natural process, so why bother?

Even if the stated sea level rise is accurate (0.12 inch per year), that isn't exactly a flash flood. Places like New Orleans demonstrate that you can live at or below sea level and manage it with engineering.

If it came down to it, we'd build or we'd move 1000 feet inland and be good for another 5,000 years.

The calamity and chicken little shit is overstated because it is about the money; always is.

PM_me_your_math··on The 'Atlanta Magnet Man' is saving our car tires, one bike ride at a time
Pushing a trailer doesn't really work. You'd need an apparatus big enough to hold magnets and FOD, and allow you to steer unobstructed. A purpose built vehicle with a cab-over design would be easier to control.
PM_me_your_math··on Reddit signs $60M content licensing deal with AI company
Because it is reddit, one of the most vile companies on the planet.
PM_me_your_math··on Ask HN: Anyone left software to study non-STEM subjects?
You only have time if you make time.
PM_me_your_math··on Man who shoveled new channel into Lake Michigan convicted
Is he not a member of the public?
PM_me_your_math··on Man who shoveled new channel into Lake Michigan convicted
Rivers change their natural state constantly. What the guy or group did shouldn't be criminal insomuch as it only takes one storm to cut a new channel. I take issue with government putting the lives of little birds and mounds of dirt over the lives of its citizens and their livelihoods.
PM_me_your_math··on Ask HN: Who are the "snake oil salesmen" of tech?
Democracy is hell on earth. Whether it is a system of government, or a means by which groups make decisions or peddles their wares. The majority tends to encumber, enslave, and/or murder the minority. The eventual outcome of any purely democratic state or process is tyranny. This is why the founding fathers choose a republican form of government that uses democratic processes. Recall that Socrates was sentenced to die by a majority vote. With that in mind, then yes, the faux value assigned to "tech influencers" is a form of democracy that's just as poisonous as people who seek to "save democracy."
PM_me_your_math··on TinySA – small spectrum analyzer and signal generator
The TinySA is excellent for finding sources of RFI, although you want to use a small yagi or loop antenna.
PM_me_your_math··on Ancient City Found in the Amazon
I just wish there were more images. There are usually only one or two on this types of articles.
PM_me_your_math··on SpaceX is suing to bust up federal union protections
Unions are cancer. This isn't the late 19th century anymore. Unions do very little but enrich themselves and exert political power.
PM_me_your_math··on Another crackdown on Boston-area pirate radio stations
All the best pirate stations are on HF. Ballsmackers on 6960khz / Fridays & 0200UTC is my fav.
PM_me_your_math··on Children, left behind by suburbia, need better community design
The article is a joke, and so is the author. Everyone says we should listen to the youth because they are young. Meanwhile, the young are inexperienced, irrational, and mercurial with a very limited perspective helmed by an under-developed brain and an even less developed sense of self and purpose. Teenagers eat tide pods and routinely kill themselves or their friends (or others) driving drunk. The question is, why do we need advice from high school students? Easy. We don't.
PM_me_your_math··on California employers must reimburse remote workers for all necessary expenses
You might want to retake your constitutional law courses. The Commerce Clause (Article I, Section 8) grants the government power to regulate business. It does not grant citizens the right to do business. The right to do business and participate in commerce and trade is a natural right. You do not allow businesses to exist. You are nobody.
PM_me_your_math··on FCC aims to reinstate net neutrality after us Democrats gain control of panel
You can always trust politicians to do the exact opposite of their claim. For example: inflation reduction act, affordable health care act, voting rights act 2023. The propaganda is strong with net neutrality. It is just another play for more government control over information.
PM_me_your_math··on Unity’s new pricing: A wake-up call on the importance of open source
There is what they say, which is often not exactly what they do. And even if the intentions are good, behavior or scenarios not conceived may emerge.
PM_me_your_math··on Touch Pianist
You're right. It is amazing.
PM_me_your_math··on California moves to decriminalize use of magic mushrooms, other psychedelics
If you go outside, you will see what unfettered access to drugs does to a society. Of course, you don't need to go outside to see it, since you can do a search and find plenty of examples and studies. The truth can exist, even if someone doesn't want to do your homework for you. Late 19th century China comes to mind. Right now, one only needs to walk the streets of LA, NYC, Chicago, Charlotte, Orlando, Detroit, San Diego, Philly, Houston, San Antonio, Austin, and any other city. You will see this on the streets: https://www.youtube.com/watch?v=e72zMER95ps

Is this really glamour? How is it helping, exactly? I don't see any purpose to unrestricted access to these substances, unless your goal is to shatter and/or destroy the lives of 20,000,000 Americans.

I'll add that I think people should have a choice, but rights cease being rights when they impose on the rights of others. Weed, tobacco, and alcohol are legal, but that doesn't mean there is no cost to society. People do stupid shit after smoking. Tobacco has health care implications. Alcohol destroys families. Free access to fent, heroin, crack, cocaine, lsd, meth, and even mdma is going to incur a very big cost. Those are non-starters. And while I think mdma can be used under medical care, abuse of that specific drug incurs a debt.

Imagine complaining about the only store willing to invest the capital in a small town.
PM_me_your_math··on Chicago’s parking meter disaster
So the double amputee with no feet is going to bike to go food shopping?

America isn't Europe. We have spaces between places and are not packed in like sardines.

PM_me_your_math··on ‘Blame the Boomers’ for Surging House Prices, Barclays Says
Yea, don't blame the current administration for printing more currency and the fed for raising rates, making new mortgages a non-starter. Don't blame government for giving colleges a means to sell worthless unproductive degrees at premium tuition with inescapable terms that hurts the applicant's earning potential and buying power. Don't blame the myth of "following your passion" as a means for earning a living, while simultaneously killing the work ethic of a generation. And don't blame the people who made poor decisions, despite the volumes of information available.

Just blame old people who have worked hard their entire lives, and never knew the conveniences and luxuries that the younger generation now takes for granted.

The article does two things extremely well. It is shores up the stereotype of young people not taking responsibility for their own shitty decisions, and it absolves leadership of the consequences of social engineering.

PM_me_your_math··on Chicago’s parking meter disaster
Who is deciding what is in the best interest of "the people?"

Motor vehicles are an absolute necessity in the United States, both for economic and personal reasons. If people didn't need cars, they wouldn't buy them. Mass transit will never be able to replace motor vehicles, and trying to shoe-horn an wholly ideologically-driven agenda will blow up in everyone's faces spectacularly.

PM_me_your_math··on Car was stolen from a driveway in Canada. We found it in West Africa
Because of corruption at the port; from the dock worker to the super, to the politicians and everyone in between. Everyone gets a little slice.
PM_me_your_math··on Why Socialism? (1949)
Sanders has three houses and net worth of 2 million dollars.
PM_me_your_math··on Why Socialism? (1949)
Think of the context. WW2 was absolutely a team effort.
PM_me_your_math··on Why Socialism? (1949)
Socialism turns into the survival of the fittest as the civilians start fighting each other for food, and positioning themselves favorably for scraps by burying their neighbors for "crimes against the state." Everything anybody needs to know about socialism was already experienced by and written about by Solzenichen.
PM_me_your_math··on BMW: Gasoline Car Ban Poses “Imminent Risk” to European Automakers
In the last 70 years, not a single dire risk warning from the church of climatology has come true. Not one.

But now we're super-cereal! Believe us this time guys. It will happen unless you buy products and services from ESG cult companies in my portfolio...

PM_me_your_math··on BMW: Gasoline Car Ban Poses “Imminent Risk” to European Automakers
Gasoline doesn't cause the jet stream to move north.
PM_me_your_math··on BMW: Gasoline Car Ban Poses “Imminent Risk” to European Automakers
That's funny considering the church of climatology can't exist without government subsidy.
PM_me_your_math··on Calls to tax the superrich grow as economic inequality surges
The rich already pay more taxes annually than most people will earn all year. 70% of the tax burden is carried by individuals earning > $120k/year, which is 30% of the population of the United States. This does not include the income that high-wealth individuals create through salaries and expense spending, both business and personal; all of which is taxed, and none of it exists without them. If it is decreed that wealthy people are 'guilty' of being successful, (that somehow, the rich got rich by taking something the poor doesn't have) then the wealthy will roll back spending and investment, which only means less opportunity, less jobs, and less income (and thus less taxable income.)

Half the country does not pay any significant income, property, or payroll tax.

To the same end, everyone is lifted up when prosperity is high. Tax revenues grow, opportunity is spurred, and people pull themselves out of poverty as a result. You cannot make someone rich by making someone else poor. The net effect will always be zero if you do not let people find their own way.

The myth that the rich don't pay taxes is nothing but class warfare propaganda.
