Woah, just now learning about Tusks from @bardi

I’ve been posting about wanting blogging to feel more like posting on here forever and…I think this gets me there. Why bother hosting a #blog and all of that hassle when your #Mastodon account could literally be a blog?

It’s amazing what a well-maintained API enables in for client apps like this. When the UI is in play, Mastodon effectively becomes infrastructure

Yeah, that's basically what I did with https://dotnet.social/@SmartmanApps/110897908266416158 - each week I covered a sub-topic with a 6-7 post mini-thread, and now I can fine-tune link to specific parts/posts when needed. i.e. the whole push for this is summed up by when I talked about e-calculators (the bane of Maths teachers/tutors) at https://dotnet.social/@SmartmanApps/111164851485070719 having covered all the relevant mathematical theory by that point (which I can also link to specific posts as needed).

Im currently working on trajectory systems and forgot what tan() does and I kinda am embarrassed about that. Also I'm awful at trigonometry apparently. Haven't thought about it in a couple decades!

@Tearcell @sinbad
Yeah, I was going to say that, 🙂 but I can also add to remember which ones are positive you can use ASTC - All Stations To Central - so tan is only positive in the first and 3rd quadrants (the 1st quadrant is top-right - where both x and y are both positive - then anti-clockwise from there).

Pro-tip for the day:

dotnet does not appear to require a trailing backslash when you define a custom NuGet package cache path via env var NUGET_PACKAGES but Visual Studio does.

Good:
NUGET_PACKAGES=X:.nuget\packages\

Bad:
NUGET_PACKAGES=X:.nuget\packages

SmartmanApps,
@SmartmanApps@dotnet.social avatar

@bradwilson
The inconsistency around the trailing (back)slash is one of the most annoying things. First I need to remember if it's forward or backward on the system I'm currently on, 😂then I ALSO need to remember if there's one at the end or not (sigh). Have these people writing these things not heard of, you know, standards? 😂

This is genuinely an important question, the open web is certainly worth saving, and I for one do think about how every task I take on might contribute to or reverse those problems. I assume we need more compassionate people at big corps, not less.

The problems no amount of compassion seem to be able to assuage include the way the entire system is corrupt and the way all our taxes are used to support an empire that turns a blind eye to poverty and supports genocide.

Good luck with that Mark.

Zoom, to me, feels like a relatively simple product. The core functionality of it has gone unchanged for years, and it still seems to provide the exact same level of responsiveness and capability as it always has.

So I'm going to need someone to explain to me exactly why the hell it needs to update itself every few days, usually when I'm late to a meeting. What is in all of these updates?

SmartmanApps,

@rodhilton @simon
I hate the latest update - my students still haven't yet found the annotate tool for the whiteboard. It went AWOL in the update. Fortunately they can still write on my shared screen, but very incovenient compared to the whiteboard. Also that annoying behaviour of I have to click on the tool I want every time instead of just once has come back again (got backed out last time, presumably due to complaints)

I just entered several groups (e.g.

I wonder if it is just because nobody posts for the past 12 hours or some other technical issues (or I just misunderstand the mechanism of it)?

@mok @mathematics
I've been in the Maths one for a while, and I can see some posts from more than 12 hours ago but less than 24 hours ago, then it's a couple of weeks to the last posts before that, so a bit spasmodic.

The other day my kid asks me to present math problems about area. Early middle school: simple multiplications and divisions. He got taught a formula for areas of trapezoids: A = 1/2h * (b1 + b2).

I decided to show him how to his solution, by giving him a different approach: A = a + 2b, where a = area of the square, and b = area of each triangle on the sides of that square.

He threw a fit and refused to accept my approach, because it wasn’t the same as he had learned.

smh

SmartmanApps,
@SmartmanApps@dotnet.social avatar

@aeveltstra
But they're not given a nor b, therefore there's no such formula as A=a+2b. They are only given h, b1, and b2, so rewriting your formula into the information they are actually given (the first line of working out is writing the formula, then substituting the given values into it) it would actually be A=hb1+h(b2-b1)/2=h(b1+(b2-b1)/2), so it's either memorise that formula or A=h(b1+b2)/2. Which would you choose to memorise?

SmartmanApps,
@SmartmanApps@dotnet.social avatar

@aeveltstra
"Educators should avoid making belief that the approach they teach is the only possible one" - we don't teach that. We do teach that this is the simplest formula.

"You cannot verify your approach by repeating it" - the approach has already been verified in the proof of the derivation of the formula, which is shown at the time we teach the formula.

SmartmanApps,
@SmartmanApps@dotnet.social avatar

@aeveltstra
"my kid’s response proves" why we don't try and teach them 3 things at once.

"testing the pupil’s application of it to the problem" - the teacher does that when they mark it.

"The choice you present assumes they aren’t" - does nothing of the kind. Only does what every teacher does and teach 1 thing at a time.

"prior choice to teach your simplest formula" - we don't teach only the simplest formula, but we only teach 1 thing at a time. Composite shapes is a high school topic.

SmartmanApps,
@SmartmanApps@dotnet.social avatar

@aeveltstra

"Do you wish you retract that statement?" - no, why would I do that?

"I also am not trying to teach 3 things at once" - trapezium area, composite shapes, unit testing.

"should be a middle if not a primary school topic" - one thing at a time. What do you propose moving into high school instead to make room for it?

Much of the Internet "debate" about algebra seems to stem from lack of awareness of what the subject is (versus the arithmetic method it was long ago) https://tinyurl.com/2p9myzt5

SmartmanApps,
@SmartmanApps@dotnet.social avatar

@KeithDevlin
It seems you haven't read any of the debates. You said "you are no longer doing algebra, you are doing arithmetic" - precisely! And the debates are around whether "implicit multiplication" is a rule or not (it isn't). Without fail every person who gets the wrong answer (this is a high school Maths question with a right or wrong answer, no "it depends" answers) has forgotten the rules of Terms and The Distributive Law, and THAT is what the debates are about. https://dotnet.social/@SmartmanApps/110897908266416158

SmartmanApps,
@SmartmanApps@dotnet.social avatar

@KeithDevlin
P.S. I would presume you are familiar with the concept of "teachable moment". Well, maybe you saw this as a "teachable moment" about the history of algebra, which is fair enough, all good. But the people are ACTUALLY arguing about the rules of Maths, and so it is a teachable moment about the actual rules of Terms and The Distributive Law (which many adults have forgotten about). And I've subsequently had some of them thank me for teaching them the correct rules.

I was terrible at chemistry coming out of school.
But I just randomly saw a YouTube video of someone doing molar calculations and decided to see if it made more sense now.

It is totally intuitive! I sadly remember when I first started that course that it felt like it would never make sense.

SmartmanApps,
@SmartmanApps@dotnet.social avatar

@poppastring
As a Maths teacher/tutor, I see a lot of students who THINK they are bad at Maths, but what I invariably find is their arithmetic skills are actually poor (the standard is to be able to answer an up to 12 times table question in 2 seconds, and we're talking not even close for these students), which is like trying to build a house on faulty foundations. Invariably once I start getting them up to speed with it they start feeling CONFIDENT with Maths now, and don't hate it anymore!

Yeah, as a tall person especially, they're really nice to drive. Plenty of leg-room. My 2nd car was a Mitsubishi Starion (I think from memory in America they were called Galaxy Conquest or something like that), and yeah nah, not much leg-room. Didn't handle as nicely as the 260Z either. Being a newer car it had more creature comforts, but as a sports car nowhere near as good as the Z. I would've really loved to have tried a 300ZX too, but never did.

OMG!!!

For years, the antivirus software company harvested information from users’ web browsers without their consent.

And SOLD that data!

Though I have never used any of their products, I pray that this company is sued into oblivion.
