Hi, this is Andre. I'll be writing about software architecture and development, cyber security, UX/UI topics, politics, and queer experiences. I'm a classically trained musician and music composer, band director, and music instructor. I'm handfasted, have kids, and play and create (video) games. Sometimes I don't recognize social cues.

I took some time today to learn how to make a trendline graph for statistics pertaining to 2 similar processes for one of my clients. This is created using , a visualizer by the company. The does not switch to dark mode easily: it takes a lot of tinkering to get it to look good. As far as goes, Qlik can improve their application a lot.

I just realized that this visualization won’t be insightful for most colorblind people. I’ll have to add symbolic markers.

Please, makers of email subscribe and unsubscribe systems, stop allowing just anyone to supply any email address. That’s just asking for abuse. Stop putting your trust in random anonymous strangers.

What you should do when having someone subscribe: send a confirmation email to their address, with an expiring link.

What you should to when having someone unsubscribe: put an unsubscribe link into their email with a unique identifier that finds their subscription and instantly unsubscribes.

Nay-sayers to instant-unsubscribe links in emails tend to defend bad practices by email clients that will read the link before the user activates it. Email clients do that in an attempt to precache the linked page, to make it show up faster when the user does activate the link. Of course by that time the unsubscribe action already happened.

The correct course of action is to use a better email client, that won’t act that badly.

Thanks, .

@strypey One would hope, but I still encounter ones that don't use that.

Reflection considered harmful

In the and OOP programming languages, is used to not only review an object’s private fields and methods, but also to access and change them.

This is used for instance by large libraries and frameworks, by preprocessors, and of course by the standard library itself.

It is dangerous because it can break a class’ definition of what should be private and inaccessible.

Every programmer should know.

I'm building , an anonymous registration of and people, intended to match missing against murdered people's profiles. My spouse is a forensic genetic genealogist who specializes in marginalized communities and found existing sources to be lacking in their ability to search, match, and review.

Umpire is being built in vanilla PHP, HTML, JS, CSS, and SQL, backed by a MySQL database. The intent is to distribute the system as , and have instances around the world federate with each other much like instances do. We already created a different application (written in Python and SVG) that can extract the data and turn the people's profiles into paper posters and social media posts. We seek to keep the tech stack as straightforward as possible, to allow easy collaboration.

reports that for April 2024 will break connections due to changes.

The fix, according to Microsoft: either skip this update or uninstall.

American cops won’t save your kids at school when they’re being gunned down, but if they speak freely, they will come with riot gear and snipers to shut them the fuck up.

In my bus, in the seats in front of me, sit what appears 2 new students from Rutgers U, very much infatuated with each other. Both look like masc girls. One looks goth with safety pins in her ears and purple nailpolish. Neither wears any other make up.

My adventures in trying to eat healthy have exposed me to a lot of things advertised to women and branded as healthy that... really don't seem any healthier than my manly-man-diet.

Oh, look, yogurt is healthy, right? It's lower in fat than cheese!

... Except you don't fuckin' eat a cup of cheese. You eat WAY more yoghurt, I can't imagine this is actually any healthier than cheese.

aeveltstra,
@aeveltstra@mastodon.social avatar

@Craigp As long as those fats are unsaturated, and the sugars are raw, you should be good. The human body needs both. Be careful with saturated fats and processed sugars, as they damage blood vessels and brain tissue. And match your caloric intake to your activity level and food absorption level. Personally, I need high-caloric foods because I have a malabsorption issue.

On which note it's worth reminding Americans that Brits do NOT say:
— elevator
— sidewalk
— railroad
— faucet
— crosswalk
— automobile
— 18-wheeler
— bellhop
— drugstore
— freeway/highway/turnpike/interstate
— parking lot
— attorney

(There are synonyms/equivalents but these are specifically AMERICAN things that flag you up as a foreign devil.)

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

aeveltstra,
@aeveltstra@mastodon.social avatar

@SmartmanApps Ah. But I didn’t try to teach 3 things. The kid already knows the middle-school, grade 7 way of calculating the area of a trapezoid. What I’m teaching, is just 1 thing: how to check whether the calculation was performed correctly. Wouldn’t teachers want pupils who can double-check their work? Out here in my line of work, that ability is very valuable.

aeveltstra,
@aeveltstra@mastodon.social avatar

@SmartmanApps Yes, one thing at a time. And instead of teaching a formula to memorize, without any understanding of how it came to be, what should be taught is that understanding. This is as easy as teaching kids addition: here’s a shape, there’s a shape, oh, and look, a third shape that is the exact same size as the first. And each of those shapes have an area calculated by multiplication, which they already know. Build upon prior knowledge.
