Gregory's Server41. Dark Patterns
Dark patterns refer to the repertoir of UI designs and techniques intended to trick or coerce a user into doing things or agreeing to things either with or without their knowledge. a windows prompt that registered closing the window as agreement to upgrade, prompts that give only the choices “ok” and “later”, or sign up sheets that hide the “skip uploading my contacts” link with a small dim font (twitter). If you do any of these, I think you’re probably a rapist too.

so, serious question about where to go next: I have started to include, sparingly, general design and cognitive psychology principles, which I had been avoiding as while they apply, they’re not *directly* and obvioisly about UI in the specific. should I go ahead and start including more of that stuff? the lawsofux didn’t shy away.  42. for legible body text, optimal line length is 60-70 characters per line. no fewer than 35, no greater than 80. going longer than these ranges makes it difficult for the eye to track back to the beginning of each line. go shorter and reading becomes stuttered, like reading a telegram. or a toot. 43. The web, and UI frameworks will fight you on this, but if you establish a vertical rhythm in your typographic grid, you’ll increase the feeling of unity in the design and help the eye flow better across the design. Choose a verrical spacing that suits the size and style of your main text font. there’s no hard and fast rules, but it’s good to aim for the vertical spacing to be around 1.33-1.5 the point size of your body text. heading sizes can be neat integer multiples of 1/2 or 1/3 of main 44. Past the age of 40, vision tends to decline at a steady pace. mine certainly has. Us old people can’t really deal with font sizes much below 14pt- which tends to look large and goofy to younger folk. whatever size you choose or however you set up your grid, please gracefully permit users to override your choice, and ideally design and code your thing to not break when this is done. this isn’t just politeness, it’s the law in USA, the UK and Australia, along with the rest of WCAG 2.0 45. in olden times, type was carved by hand into metal for each type size. the different sizes were not just scaled versions of the same design: tiny adjustments were made for each size for color and workarounds for printing technology. With the invention of computer fonts, "hinting" was only done for screens at small sizes, wrong anti-aliasing later accidentally mimicked the effect. Few noticed laser printed documents looked slightly wrong or why. Now retina screens have the same issue. 46. Untitled%20toot%208_FINAL.docx 47. Optical Adjustment 48. Things that work different should look different. 49. Figure-Ground and sillouettes. The fastest and most well developed stage of visual recognition is of the sillouette of an object. In character design, getting the sillouette of a character to be disctinct is most important. in portraiture if you get the shape of the head right, you’re 90% there. it takes far longer to notice the interior features. time how long it takes you to spot what is wrong with adele. This is important in icon design too- don’t mask all your avatars in circles please 51. Humans make mistakes. It’s no use pretending they don’t. You’re just going to have to deal with it. So just make them easy as possible to fix. Include infinite undo, back button, home button, version control. Autocorrect, I am not so sure about. I for one don’t like the computer to insist it knows better than me and then provide no way to easily insist i am right. Let me make mistakes! just make it easy to fix them. 55. All manufactured things should be designed to be used by one hand. either hand. there are safety features of some industrial equipment that require both hands so that both hands are no where near the dangerous hand mangler part- use best judgement via @space_cadet 56. on Unskippable Cut Scenes. 57. Negativity Bias 58. more on episodic memory ever stand up to do something, walk into another toom and forget what you were doing? it turns out there’s a reason for this. since human memory is organised around episodes, experiments have found that walking through a door is a trigger for ending an episode- the result? short term memory is cleared and primed for new input. what triggers exist in software? how often have you picked up your phone to do something, saw a notification and lost your flow? 59. Please don't use confirmation dialogues, but if for some reason you absolutely must, don't sleepwalk through writing the the messages and the button labels. Don't just label them "okay" and "cancel" Without thinking about whether that wording harmonises with the message text. If possible, label the buttons as what they actually do, specifically.  @zensaiyuki This is exactly why I advise against using JavaScript's alert(), confirm(), or prompt() functions: They don't allow you to label your buttons anything other than "Okay" & "Cancel". I generally prefer native UIs, but in this case: PLEASE implement your own! Preferably something non-blocking like GTK's InfoBars. 60. Plan for failure software breaks. hardware fails. services go down. users make mistakes. Anticipate as many failure modes as you can, and design recovery plans and craft reasonable, well written communications for the user. Technical writing is its own topic, but for error messages the important things to accomplish are 62. Stop making your updates so intrusive. I open an app to use it. if you force me to stop and update it first i forget what I opened it to do. this is user hostile behavior. Ideally, users should not be bothered about updates at all- but unfortunately they a necessary. a less intrusive pattern is asking for permission to download and install an update on app EXIT. just don’t ask using a blocking modal dialog, for the love of durga. the least intrusive pattern of all is web apps that are just automatically always the latest version, and at worst, occasionally ask you to reload your browser so the front end matches the back end. this is a tradeoff of course because those updates happen without consent.  @zensaiyuki @zens yep. As any D&D player will attest: 1% is a lot higher chance than you think 68. don’t assume your users’ devices resemble yours or your close circle of friends when deciding minimum requirements- especially if you intend to reach a wider audience with a range of socioeconomic conditions and internet connection speeds. brought to you by the Australian government locking welfare payments behind a mininum iOS version.  @zensaiyuki@mastodon.social It's a fairly straightforward argument to make that this is illegal per GDPR too, data minimisation is a binding legal requirement and demanding people register when there's no actual necessity seems to contradict that  @zensaiyuki i couldn't figure out what was wrong with Adele until i put her upside down… i hate it. @zensaiyuki It's worth noting: This is why FontConfig is part of GNOME's text stack! To allow font designers to distribute multiple font files for a single font family, so they can perform these optical adjustments for each relevant size & style. @zensaiyuki I think this idea of different fonts [in the old sense, where font implies a size as well as a typeface] not just being scaled versions of each other is something that OpenType tries to address with its parametric features. There doesn’t seem to have been much uptake of the feature though. @futzle past a certain threshold of nuance, people tend not to care. they might have the odd feeling that one peice of design seems nicer or “more expensive” than another peice but they won’t be able to put a finger on why. this level of care in web typography basically represents the tip of the diminishing returns curve: lots of effort for an implacable feeling  @zensaiyuki where's the line between malice and incompetence on this one? When Windows 10 warns me it's going to restart to install updates: Is this a deliberate dark pattern, or a stupid mislabeling of buttons?  @zensaiyuki I've read a bit of Foucault and I think that what English speakers call a "dark pattern" (that we call now "deceptive design") is what Foucault calls a dispositive of power, merely restricted to computers. Foucault died before the web was a thing.

I don’t say that last part to be hyperbolic. lack of respect for other people’s consent runs deep and affects everything you do. Implementing a dark pattern is a fucking sign.
