It'd be great if you could get someone, anyone who is responsible for your Maths programming to read https://dotnet.social/@SmartmanApps/110897908266416158 - in particular when I covered the topic of e-calcs https://dotnet.social/@SmartmanApps/111164851485070719 where I covered the DIFFERENT ways that the different MS products do it wrong. The Windows "standard" calc says that 2+3x4=20, in "Scientific" mode it says that's 14 but also says 8/2(1+3)=8/(1+3), etc.

Strange question, but can you bundle #dotnet tools with a dotnet publish? These tools are part of the tool-manifest.

There is just no question in my mind that the culture of the fediverse (by any name) is a better model for civil discussion. But oddly, even many of its biggest champions have largely returned to Twitter, or pivoted to Threads, which may be a step up from Nazis, but thatโ€™s a pretty fucking law bar.

I noticed that and I'm thinking some of them aren't checking where the engagement is coming from. I recently, in a rare moment, engaged in some conversation there (I was all up to date with here, so, oh well, let's see what's happenning there), and one time I got back on I had 8 notifications, but I checked the profiles and 7 of them were likes from porn bots (and only 1 of those 7 was "this profile is hidden due to suspicious activity").

I've been noticing whole-machine slow downs whenever I heavily use my Dev Drive (for example, building source) that are just unacceptable.

A common example is I'll start a full build in Visual Studio and then go to type in Windows Terminal and everything I type will be delayed by multiple seconds. Even pasting will show only a few characters at a time.

So, back to raw SSD and (sigh) NTFS for now.

    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!

    Yeah, I was going to say that, ๐Ÿ™‚ 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

    @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, ๐Ÿ˜‚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? ๐Ÿ˜‚

    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.

    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?

    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)?

    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 wasnโ€™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 kidโ€™s response proves" why we don't try and teach them 3 things at once.

    "testing the pupilโ€™s application of it to the problem" - the teacher does that when they mark it.

    "The choice you present assumes they arenโ€™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.
