@davidho

Taxes don't fund federal government spending.

@mjgraves @davidho What does? (I'm not American)
@vonxylofon @davidho Government spending is how the currency is issued. You have to earn it. Only then can you pay your taxes. Taxation is the end of the life cycle. Not the start.
@mjgraves @davidho But what happens with the taxes collected? Do they all go to the state?
@vonxylofon @davidho Taxes collected are basically currency being extinguished. Like a bathtub being drained.
@mjgraves @davidho Care to provide some source or elaboration? Because it doesn't check out for me on several levels. Granted, I've only attended a handful of economics subjects.

@vonxylofon @davidho It's really a basic understanding of fiat currency. Government wants to provision itself. It wants workers & supplies from the private sector. So it levies a tax, payable in a token that only it issues. Now people need to work to earn that token. 1/2

@vonxylofon @davidho The classic example is the Imperial English in Africa. They want local workers for the port. So the levy a "Hut Tax." Locals must pay the tax or the Army burns down your hut. The hut tax is payable in English script. Now the locals are motivated to work for that otherwise useless stuff.

Also, illustrates the fact that all fiat currency is ultimately backed by violence. Threat of imprisonment. Don't pay your taxes. You go to jail.

@mjgraves @davidho if I could wish for everyone to understand one thing about our government, it would be this.
@mjgraves @davidho I was going to go towards that route. In the UK we hear politicians say we will increase tax X to fund Y in the NHS. It is just not true. It does not operate like that.

Even as common knowledge in your field, it's still shocking, no?

@davidho (IT Professional); Hackers don't typically succeed because they have insane technical skills and expensive equipment. They succeed because Linda in Accounting has a lack of critical-thinking skills and/or is careless.
@RestlessLipSyndrome @davidho Right!!! Which is why the Robin HOods of the world should be exploring that stuff. THis morning I was imagining the Rockford Files for this decade b/c the main character was always quietly conning his way into places (as opposed to burglary).
@geonz @RestlessLipSyndrome @davidho I got a bank to open up after hours… lucky for them I’m not a thief lol their internal security was off and just the safe & door locks were active. They told me this as they were cashing my check. (Tiny bank in hell knows where in Tx.) Hacking people is surprisingly easy.

@RestlessLipSyndrome @davidho I very much dislike the spin of mapping the stupid decisions of Bob the CEO of giving Linda an IT environment where simply opening up #email attachments or URLs - which is part if her job - may cause the whole company get hacked.

We #IT #security professionals need to fix that spin that clearly supports the megacorps selling insecure crap instead of investing in real-world security.

@publicvoit @davidho
No doubt, investment in robust security features is absolutely necessary. I am constantly annoyed though with private businesses both small and large that see IT infrastructure and security features as an expensive nuisance. It's just a dumb upsell until their environment is crippled by ransomware and then we the IT professionals have to step in and mitigate these dumb and greedy decisions.

@RestlessLipSyndrome @davidho some interesting choices in this diagnosis of the problem.

From the lack of critical thinking in assigning culpability to a presumably low paid individual rather than seeing it as a systemic problem
To carelessly assuming gender of the person whose personal failings you appear to be seeing as causing the problem.

We IT Professionals need to do better than this. And if we don't, we shouldn't be surprised when Linda in accounting ignores us ...

@colo_lee @davidho
Would you rather me use a real-life example of a lawyer who is a partner at a top LA entertainment firm who refuses to use 2FA (and puts not only the entire firm but their celebrity clients at risk) because they find it annoying?

Any IT pro knows this runs the gamut from the lowest paid intern to the top person in the food chain at a company and gender is not a factor in who ultimately makes a critical mistake. Mastodon doesn't let me write thorough dissertations in one go.

@RestlessLipSyndrome @davidho That would be a less offensive example, yes.
@RestlessLipSyndrome@mastod, yup -- if you're going to punch, then punch up, not down :-) on.world @colo_lee @davidho

@RestlessLipSyndrome @davidho @seawall

Mmmmm. Yeah I’m gonna disagree with your blame-culture assertion there. Linda in accounting doesn’t lack critical thinking skills. Linda is busy trying to make sure the bills get paid and that sneaky dude who always fudges his expenses doesn’t get away with it. Linda is tired because she’s doing most of the housework and parenting whilst working full-time, and her kid is sick. Linda also has a boss who keeps making gross jokes. Linda makes human mistakes.

@RestlessLipSyndrome @davidho @seawall I agree that many (most) security breeches are human error, of course. But let’s not frame it as people being careless or stupid :-) nobody will ever catch 100% of tricks. We have to design systems with a level of error tolerance in mind.
@nat @RestlessLipSyndrome @davidho @seawall Great deconstruction there friend. Respect to you
@RestlessLipSyndrome @davidho Why did you specificaly use a feminine-associated name to depict someone as incompetent and/or stupid?
@KekunPlazas @davidho Because the majority of offices I have worked in or with had women in these style of positions? It's my lived experience.
@KekunPlazas @davidho It is also to say that non-technical office staff usually need the most training to prevent security breaches. This is just the reality of office IT.

@RestlessLipSyndrome @davidho
Exactly.
When I did my IT course on networks and security (15 years ago now), the lecturer asked us how we'd go about gaining hostile access to a company.

I went last (being old and grizzled). I said "Get a job there. As a temp is fine. Make them *give* you access."

Jaw drop.

By the end of the course it was in his notes.

a four year old who doesn’t know the alphabet or numbers above ten but exerts boundaries such as “I’m using this. You can have (the) next turn” is more likely to succeed in school than a four year old who can spell and add but doesn’t know what to do when someone else wants their toy

@chaspinrad @davidho this is becoming more obvious to me as I've shifted to homeschooling my autistic child after his funding for TA support was cut. The Ministry of Education seems to think that his advanced reading level means he's "fine", never mind his poor emotional regulation and delayed social skills 😔
@chaspinrad @davidho He/She is not only more likely to succeed in school, but in life.
@davidho Bleeding is stanched, not staunched; two spaces after a period is now passé—one is correct; editors accept manuscripts with with errors and typos all the time—it’s the quality of the writing that counts.
@davidho Haha, and they also make mistakes, especially when preaching about typos. I used to accidentally call myself an ediotr, which seems very apt!

@thelmadonna @davidho That's Muphry's Law.

I was pleased to find the phenomenon has a name.

@thelmadonna I know one person who still uses two spaces after a period, and I found that out two weeks ago. That was shocking.
@Sumocat Here’s a deeper dive on the issue of spacing after a period: https://cmosshoptalk.com/2020/03/24/one-space-or-two/ Editors will not reject a manuscript based on whether or not the writer has conformed to house style, which pretty much always specs a single space after a period, but they may go ahead and just change it. 🤓
One Space or Two?

It hasn’t reflected publishing standards since the Jazz Age. And it isn’t Chicago style. But some people continue to do it in their own documents—from manuscripts to emails. You’ll even see it occasionally on social media.

CMOS Shop Talk
@thelmadonna @davidho Being a teacher of Spanish, such nuisances of English writing annoy me, not only because English is not my native language, but because for DECADES grammar checking tools for Spanish were written by English-speaking people that did not know punctuation rules differ between languages.
In Spanish, dot comes after quotes, a single space comes after dot, and the em-dash come in pairs, —this way—, with spaces before the first and after the second.

@thelmadonna @davidho

> one is correct;

It turns out that, astonishingly, one is permitted to use any number of spaces after a period and no one can stop you, and no one corrects you either way.

I moved from two to one and then back to two and not one person ever commented or cared, including editors.

(I moved back to two when I started adding more whitespace in general, because my eyesight is slowly deteriorating.)

@thelmadonna @davidho

Nah, two spaces after a sentence is good. I like the clarity.

@davidho In the radiocarbon field, 1950 is modern.
@RadiocarbAnn @davidho A friend who as a student was taking an art history course, a European archeology course, and a paleontology course at the same time said she'd hear a date like six hundred or six thousand years ago and have to sort by context to remember if it was incredibly recent, really old, or pretty ordinary.

@tjradcliffe @RadiocarbAnn @davidho

That sounds like a fascinating problem to have! 🤔😎

@davidho
Your local #Library is probably part of a network that can get you just about any book you need, if you aren't in a rush for it

#InterLibraryLoans let you have the materials for 21-30 days & will usually even renew them once

@PeachMcD @davidho this is how I've been getting my most of my books as of late, it's uncommon to do it but academic libraries have zero problem placing interlibrary loans for pleasure reading at most universities and they have significantly wider interlibrary loan networks then your standard public library.

I'm in western Canada and I think the last book I read came from a library in Brooklyn

@davidho That the results of your spin were decided before you even pushed the button or pulled the handle on that one-armed-bandit. When I tell people the math and reality behind slots they are actually offended that I'd question their ability to "win at the slots". I don't work in that particular domain anymore, but it's still pretty funny to see the superstitious struggle with the facts of math and blatant emotional manipulation.
