Commented in 'Companies will do everything but pay you a living wage': McDonald's blasted for viral 'free iPhone' promise to applicants
Let's say the average franchise has 20-30 workers, We'll say 25, that is 8.3 workers per shift. Of those 25 I'm guessing 5-10 are part-time. So I'm going to go with 15 full and 10 part-time workers for this. Let's say the full time staff are making $10 or $400 a week. The part timers are making minimum wage, let's call it $7.50 or $150 a week. OK, so now let's go with the "living wage" of $15 an hour, that means the full time group is now making $600 a week and the part timers are making $300. We'll guess and say they need 5 full and 5 part time employees, you only get the iPhone if you stay for 6 months, which is about 26 weeks. With the living wage rate of 15 that equals out to $45,500 extra those employees would get... then since the ad doesn't say what phone, we'll go with the cheapest new iPhone the SE at 400, 400x10 is $4,000. So it's a no brainer from the business standpoint for the franchise to offer the iPhone over a higher wage. I will also point out Illinois already pays $10 as minimum wage for non-tipped people, meaning my math is off for where this is actually happening but doesn't change the fact that a business owner would rather buy iPhone's than pay more.
I'm not saying that higher wages aren't a necessity, I'm just pointing out that franchise operators aren't always in a position to offer more. After they buy the materials and ingredients from McDonald's or McD's mandatory partner. They then have to pay McDonald's part of their yearly intake, on top of that my understanding is that McDonald's owns most of the real estate and the Franchise owner has to pay that lease too. Then you have, electricity, water, payroll, taxes, trash, etc...
Here is what they pay to McD's, it's interesting:
Ongoing Fees
During the term of the franchise, you pay McDonald’s the following fees:
Service fee: a monthly fee based upon the restaurant’s sales performance (currently a service fee of 4.0% of monthly sales).
Rent: a monthly base rent or percentage rent that is a percentage of monthly sales.
Mashed says that the average store brings in 2.7mm a year, but after fees, payroll, the costs of buying the food, etc it works out to the average store profit of just $150k. The initial cost to open one is $1,000,000-$2,000,000. So it's going to take 10 years just to pay off the initial investment to open a McDonald's at the 150k profit margin. So the $15 living wage has the ability to absolutely destroy that profit, especially if McDonald's Living Wage raises prices and McDonald's iPhone down the street doesn't because most people will just go to the cheaper one.
It's a lot more complicated than just saying raise wages.

Commented in The Black Hole Information Paradox Comes to an End
Very nice long-read. :-) It is posts like this that make my day in an inspirational way. I do not understand the math behind all of that, but it is explained in a very clear way, which makes it really fun. Now I am all full of wondering about the loss of information, wormholes and why they never take electro-magnetism into account of all of their research. For instance, there are four types of black hole (so far) according to this link, and in all of them electrical charge is important to describe the type. Would including electricity in the equation not change the theoretical outcomes as described in the, again: very nice, article?

Commented in Amazon says more than 19,000 workers got Covid-19
My admittedly weak math skills say that is .04% fatality rate. Assuming all the presumed cases were actually infected and all of the deaths were from positives, and none from the presumed cases who may have died from unrelated pneumonia or seasonal flu.
Number of positives, number of hospitalizations of positives, and number of deaths of positives would be far more useful data. Probably boring story/ headline and might make people wonder why we quarantined everyone to protect the sick and fragile instead of quarantining the sick and fragile.

Commented in Here’s why so many physicists are wrong about free will – George Ellis | Aeon Essays
That’s a LOT of $10 words to get to
If you seriously believe that fundamental forces leave no space for free will, then it’s impossible for us to genuinely make choices as moral beings
kinda weird considering the preceding 5000 words. Feyman said - and I’m paraphrasing - that one cannot claim to understand something if they cannot explain it in plain language terms to a layperson
also there’s this:
how can order emerge out of this chaos? As explained by Denis Noble and Raymond Noble in their paper for the journal Chaos in 2018, molecular randomness gives cellular mechanisms the option of choosing the outcomes they want
Er... begging the question much? After 79 paragraphs of molecular mechanics of chemistry of cells we just label things with conclusions? Is that how debates work when you are emeritus?
For the sake of argument, let’s [...] take the deterministic view seriously. It implies that the words of every book ever written – the Encyclopaedia Britannica, Das Kapital, the Harry Potter series – were encoded into the initial state of the Universe, whatever that was. No logical thinking by a human played a causal role in the specific words of these books: they were determined by physics alone
Wow. Clearly applied maths guy cuz that fails some basic analysis in concrete math
To muse in the parlance of our times: por que nos dos? Have you considered that determinism and logical thinking are not mutually exclusive? Or is that a deliberate false dichotomy?
stick with applied math my man. Debate is not your thing
to be clear: I have no horse in this race. I’m entirely agnostic about the free will/no free will debate
free will => pass the beer nuts; no free will => also pass the beer nuts
having said that it’s not only physicists who lay claim there’s no free will; there are also biologists like Sapolsky (see related link lecture series)

Commented in African Teen Builds Windmills from Junk and Supplies His Village with Electricity
I was going to say that I remember reading about this in HS, then I saw "That was 2002" and confirmed my suspicion.
That said, the math doesn't work out. If he was 14 in 2002 when he started building windmills, I doubt that he's 22 in 2019.

Commented in All she has to do to collect a $560 million lotto jackpot is make her name public. She refuses.
Can't you just get the money, change your name, and move somewhere else? Then you can buy any politicians/media personalities/whoever it takes to say that there was a mistake with the name, and that the real name is (whoever you hate). Then come back home and say you just were away on vacation.
If you have half a million bucks there's a lot of very simple creative solutions to this problem.
Edit: I meant half a billion. Looks like my math skills are getting down to Dr. Evil's level

Commented in FEMA Contract Called for 30 Million Meals for Puerto Ricans. 50,000 Were Delivered.
That's your typical Latin American government contract math. 99.8% goes to the guys who got the contract (with at least 90% going to the politicians involved in the deal), the rest goes toward fulfilling the contract.
Actually these guys are being generous. In Venezuela this would have been 100%.

Commented in These drones can plant 100,000 trees a day
This is a neat idea, but the math here seems heavily rounded in somewhat weird ways, so it seems like they are vastly overselling the capabilities for the current models at least.
They say 100,000 trees a day based on being able to fire 1 seed per second, but there are only 86.400 seconds in a day, so that's rounded up. Still, their 1 billion number based on 60 'teams' should land them closer to 2 Billion with that number than 1 billion they are claiming. That may be good that they are rounding that one down to be realistic though, as these are "germinated seeds" they are shooting, not saplings or larger, so there is likely to be decently less that make it to a reasonable tree stage than are planted. The number also relies on being able to work around the clock all year long, and doesn't seem to account for the refill and transport times which may be big factors since they claim currently each drone can only carry 150 'seed pods' at a time. Since these are still operated by humans (they mention a pair of operators for each 'team'), I'm doubting they would work around the clock anyway.
That all said, it sounds like this would go a long way towards improving the planting situation and speeding things up at least somewhat. If successful, I could imagine larger teams of more than 60 drones in operation, and perhaps investment into improvements such as larger seed pods, faster drones, or more automation for planting to reduce operators.

Commented in AIM will shut down after 20 years
Hey, I had a t2k! Years after a TRS-80 Color Computer, but still, it was the bee’s knees. Of course, it had been designed in between the IBM AT and XT, so it was technically before the notion of PC compatibility, but you love for the faults, right? An 80186 with a standard 80286 math coprocessor, 720K DSDD floppies, woefully non-standard graphics… That was the life. Ah, yesteryear...

Commented in A $1,000 per month cash handout would grow the economy by $2.5 trillion, new study says
You can dig through my entire history to find it but I've done this math before... giving away this much money would come close to doubling the US budget and is not economically feasible even when removing the costs of social help that would no longer be necessary.
Would I love to get 1,000 or even 500 per month from the government, hell yeah, do I think it's a viable economic plan, no.

Commented in Universal Healthcare would save $17 Trillion
Just look at your pay-stub to see what it means for you. Here is what it looks like on mine.
So far this year I have paid $215.92 into Medicare, and $825.59 for my health insurance, totaling $1041.51.
Medicare already covers our demographic with the highest medical expenses by a long shot, our elderly. For easy napkin math though, lets assume for Medicare to cover everyone it would cost twice as much as it does now. It won't, but it's an easy assumption.
My Medicare tax doubles to $431.84. I don't have to pay for any health insurance, saving $825.59. The total out of my pay would just be the $431.84.
$1041.51 - $431.84 = $609.67
I save would $609.67 switching to Medicare for all, if it costs twice what Medicare currently does. Go look at you pay-stub. See what it will mean to you. Double your Medicare tax, eliminate your health insurance. Do you save money?

Commented in The biggest 4K TV you can buy makes your 100-inch TV looks like a baby monitor
PPI done by distance, not area. But my math is wrong in the other post.
They said 4K. I'm assume the more typical UHD of 3840px wide, not actual 4K of 4096px. They also said 19 feet. Thats 3840 / ( 19x12 ) = 16.8ppi not 3.5. If ppi squared makes more sense to you, ( 3840 / ( 19x12 ) ) ^2 = 283.7ppsi
According to this calculator you would have to be more than 15 feet away to not see the pixels. Ideally more than 26 feet. So maybe I was wrong. If you have a mansion with a real theater, this could totally work.

Commented in The biggest 4K TV you can buy makes your 100-inch TV looks like a baby monitor
I did some quick math here, I hope it's correct but with a total pixel count (based on resolution) of 7,028,736 divided by a rough total surface area of 63,119 inches, the pixels per inch I got was around 111.

Commented in Gravitational Waves Are Permanently Warping The Fabric of Space-Time
I can't begin to follow the math involved in anything relating to relativity, but I don't think you can think of time separately when talking about things at the fundamental level of gravity waves.
Think of the ball on the rubber sheet depiction of how mass warps spacetime. Gravity waves passing through that depiction permanently alter it in some way. I couldn't begin to know how but I guess what they are getting at is that that than a sine (gravity) wave passing through, bending and returning to it's previous state, it leaves behind a change (an echo perhaps?) Being able to somehow see those changes would let the really bright folks theorize and prove some more things I don't understand.

Commented in Kindergarten Decorations
Hahaha! Well, I can tell you this: the sheer joy on those faces while telling a silly story or painting five kazillion dots, just for them, makes painting good. That's how I bring it and do it. This time I had an assignment with it, a message about diversity. That's not easy while avoiding cliche's. It's my third work there, so I know the school and several of the kids. They emphasize a lot on creativity there, so there's a lot of inspiration to gather from. The bird is the only thing that came from a book, the figures in the middle are drawings from one class's coathangers (self protraits to identify the right hanger for everyone), the apple is for the name of the school (Oogappel which translates to "apple of my eye") and the part with the tree cut to pieces and rearranged is for the closeness to nature and that "diversity", as I see it, is a damn healthy solution to inbreeding. The colours are layered, so the obligatory rainbow is hidden in the absolut backgrounds and goes from blue to purple to red et cetera. Not the "right order" and that's how I like my world. And which creates a diversity of itself by that. Pretty deep talk for a few days painting. :-) But yes, with a piece of paper, a few spraycans and a good way of telling stories to those little ones made them understand the abstract of what it actually means. We're talking kids the age of four, five years old. That's neat. And that's where you discover it is not a regular school, they do not follow the same curriculum as the normal cityschools. Same things as language, math and the lot, but with a very creative twist. Yeah, even dance and physically doing things is seen as part of a total package, it comes with schooling. Not just mindnumbingly re-reading or repeating for the sake of budgets and seats for the schoolboard.
Sorry about the long story, it's late and I just got back from some friends. They cooked me a nice dinner. Which is no excuse what-so-ever to babble away, but I do not care. Those colours do a person good. :-) Aaah, the aerosols. Yeah. Hmmm. :-)

Commented in The Gig Economy Celebrates Working Yourself to Death
I do see her point on companies exploiting and abusing "gig economy" to profit at the expense of "their" employees. That shit is toxic and needs to stop.
But worker rights are never an automatic given of any system of government. They have to be explicitly fought for, enacted and nurtured actively, again and again. It is the business of business to maximize profit, it is the business of government to preserve the status quo, it is the business of the people to protect themselves and petition the government for the right to vote, right to work in safety, right to retire with dignity etc. It is exhausting and we all need to get on with our business.
And it doesn't help when people work against their own interests electing business representatives into government and denouncing protests thereof.
Be all that as it may...
At the root of this is the American obsession with self-reliance, which makes it more acceptable to applaud an individual for working himself to death than to argue that an individual working himself to death is evidence of a flawed economic system.
Not so fast. At the root of this are scarce resources getting scarcer and humans consuming them getting more and more plentiful. This juggernaut is a force of nature, it is unavoidable in that circumstance that competition is ever present. No matter which ism claims it can mitigate it, people have to fight for survival.
Is our economic system flawed? Sure.
Is it less flawed than 200 years ago? You bettya. For one thing - slavery is abolished as a legal economic mechanism. Big check.
Is our economic system getting better? Only to the extent we are willing to pursue its "betterness" and only if we measure the progress in centuries. Generations will live and die before it gets better.
Globally, life expectancy is up and rising, infant mortality deaths are down and dropping, poverty is down and dropping, infectious diseases are down and dropping, etc. The objective data is telling us that human life, on average, is better on the planet than it ever was.
Do we have problems? Yes.
Are those problems difficult to resolve? Yes.
How do we with fewer resources than ever before feed more people than ever before, and percentages of elderly are higher than ever before? I don't know... But somehow, productivity of able-bodied has to go up. The alternative is that the number of elderly has to go down. The math is clear :/ Nobody takes joy in reporting these facts but they are facts.
The unprecedented post-war economic boom which paid for worker compensations and retirement packages which were offered then and there and never before is a blimp in the long history of struggle for survival against famine. My great-grandfather told my father back in the 70s that "people never lived like this before in his lifetime or his father's". His generation remembered a time before prosperity allowed middle classes to work less and retire earlier but he never had that good fortune and neither does this generation.
In the end we will all die. Dying from work is just another way to die. We used to die a lot more from disease, famine and war. A lot of us still do. Dying from exhaustion in an ergonomic chair in an air-conditioned room is still preferential to dying of exhaustion in a poorly-ventilated mine shaft. Nobody is celebrating this macabre choice. Everyone is just trying to survive. Exploitative companies included.

Commented in Mike Pence: Trump administration planning ‘full evaluation’ of [”]voter fraud[”]
Looking through the wired article:
“Trump and others have been misreading our research and exaggerating our results to make claims we don’t think our research supports,” Richman says. “I’m not sure why they continue to do it, but there’s not much I can do about that aside from set the record straight.”
Richman himself is not backing down from his initial findings. He says that even if some people did check the wrong citizenship box, enough respondents repeatedly reported voting as noncitizens to indicate that some noncitizens do in fact vote. Even some of Richman’s detractors, such as Rick Hasen, author of the Election Law Blog, acknowledge that “noncitizen voting is a real, if relatively small, problem.” Richman says those on the left are just as wrong to reflexively claim that voter fraud doesn’t exist at all as Trump is to continue insisting voter fraud is a national conspiracy.
Here’s what the math should look like (that is, if Richman’s initial study was accurate—which many researchers doubt). If 6.4 percent of the estimated 20.3 million noncitizens in the US voted, and if just 81.8 percent of them voted for Clinton (the percentage who voted for Obama in his 2008 study), that’s an added margin of a little more than 835,000 votes. In other words: Even with all of those supposedly fraudulent ballots, Clinton still would have won the popular vote by more than 2 million votes.
AKA ... that didn't disprove the republican nutters I linked. If anything, it didn't provide an accurate critique of Richman's results, found here. You have to go for a paywall for that. But there's an app for that. These researchers accept the results. These one only acknowledge that it caused controversy. And that is just by going off of the only 6 papers that cite the original article through google scholar.
So no, even reading the critique, and reading the wired piece, I am still convinced that more then "0" noncitizens voted. So yes, Trump is insane, and going on about 2 million. However, much like the project veritas videos, the dead voter turnouts in Colorado, and California, the all smoke and no fire with the machines in Detroit, this is another case of another story refusing to die when it comes to election fraud in the States. Calling everything fake news only leads to more people actually reading brietbart, and RT.
And why wouldn't the left champion voter ID if it can fall under the bracket of government services? And it is a little bizarre to think that offices could not have a geographical minimum requirement, and only offer voter ID. People do happen to get passports and drivers incenses issued by the government all the time with minimal issues. It is almost as if Voter ID can be wrapped into these services. Looking at wikipedia, it seems you have seven states already with strict photo ID laws, and non strict photo ID in another ten. People can fill out a form, submit it with original and photocopied* documents/passport photo, and have the final ID mailed out, with minimal fuss. I would think solidifying attacks from political opponents by tackling the same problem, and providing a solution that falls under social services would help ensure these offices stay open. Plus, voter ID is once every 5 years. A day to get proper ID is not an issue, even with the "brass tacks corruption. "
You're right, Voter ID does sound simple enough. I have been dealing with it all my adult life, and as far as I ...
