| Vajb | not exactly a maemo question, but whats wrong in this syntax? "if answer != "y" || "n")" It works, but not they way i wanted. I wanted it to trigger if answer is not y or n, but now it triggers at any input and i can't wrap my head around it. | 06:50 |

| Oksana | if {answer != "y"} || {"n"}, I would guess | 07:23 |
| Oksana | Aka, "n" is always true | 07:23 |
| Oksana | But, I am not sure what ")" stands for in your example | 07:23 |
| Vajb | oh i mistyped. It was supposed to be (answer.... | 07:28 |
| Vajb | so it is just closing ) | 07:29 |
| *** LjL has quit IRC | 07:33 | |

| Oksana | Either way, my argument still holds. What would happen with this? (if answer != "y" && answer != "n") | 07:42 |
| * Oksana expects that || means or and && signifies and, but haven't tried scripts for a long time | 07:43 | |

| Vajb | let me try what happens | 07:59 |
| Vajb | same problem as from the start | 08:02 |
| Vajb | it just triggers no matter the letter and doesn't move to else even if letter is y or n | 08:02 |
| Vajb | sigh i give up and clean my house instead | 08:03 |
| Oksana | Is it possible in your script to print out values of answer, answer != "y", answer = "y", and others? | 08:03 |
| Vajb | i wouldn't know. Im just taking my first steps on programming :) | 08:04 |
| Vajb | they want us to learn typescript | 08:04 |
| blap | is Lisp/Scheme also on the menu someday Vajb? | 08:06 |
| Vajb | i don't know haven't check next courses | 08:07 |
| blap | scheme got me thinking in new ways | 08:09 |
| * Oksana has heard that Smalltalk is one of the most liked programming languages | 08:09 | |
| blap | the syntax though ugh | 08:09 |
| Vajb | i kinda like typescript so far, but i don't like to fail no matter what | 08:30 |
| Vajb | and now im failing no matter what i try | 08:30 |
| Vajb | to be exact. I wanna make script that asks y or n and answers accordingly. If i use any other character than y or n it gives error. | 08:34 |
| Vajb | sounds simple enough, but i don't seem to make it | 08:35 |
| KotCzarny | in bash i simply use: read ans; if [ "$ans" = "y" -o "$ans" = "Y" ]; then echo yes; else echo no; fi | 08:47 |
| KotCzarny | never touched scheme | 08:48 |

| Maxdamantus | if(["y", "n"].indexOf(answer) != -1) | 13:53 |
| Maxdamantus | Should work in TypeScript. | 13:53 |
| KotCzarny | what about upper case? | 13:53 |
| Maxdamantus | if(["y", "n"].indexOf(answer.toLowerCase()) != -1) | 13:54 |
| Maxdamantus | TypeScript seems like a bad language to be taught as an introductory language. | 13:57 |
| Maxdamantus | It has a static type system, but it relies on fairly careful reasoning to ensure your code is actually well-typed (given that it compiles) | 13:59 |
| Maxdamantus | due to its unsoundness WRT structural subtyping (assumes covariance of data structures), and its use of `any` typing, etc | 14:00 |
| Maxdamantus | and when you actually do have type errors, they're not even caught at runtime, unless they happen to be real ECMAScript type errors (in which case `TypeError`s will be thrown) | 14:01 |
| Maxdamantus | I see it as a language that acts as a pretty good workaround for the lack of type safety in ES, not as something that would be optimal to learn to understand something about programming or type theory. | 14:03 |

| Wikiwide | Feature request for camera: using an image as semi-transparent overlay while shooting a photograph. | 23:26 |
| Wikiwide | Usecase: creating time lapse sequences of photographs. Such an overlay would make it easier to avoid movement of camera from one day to another. | 23:27 |

| KotCzarny | it's easier to be done in postprocess | 23:34 |
| KotCzarny | ie. in software after | 23:34 |
| KotCzarny | just requires some key points in the scene to be permanenet | 23:35 |
| KotCzarny | *permanent | 23:35 |
| Wikiwide | Sure, but post-processing implies that the images will have to be cropped at least. | 23:36 |
| Wikiwide | Pre-processing allows to make sure that all angles and distances are correct. | 23:36 |
| KotCzarny | assuming your onion image is similar enough in the angles, distance etc | 23:37 |
| Wikiwide | Because not everybody is going to have a tripod mount sitting to specify where the photographing should take place. | 23:37 |
| Wikiwide | /me is probably too picky; hoped that gstreamer has such a image-overlay-over-camera-stream functionality | 23:43 |
