A friend of mine asked me if it would be possible to create a dot grid with increasing dot sizes as shown in the picture (without the icons):



enter image description here



I'm aware that there are tons of tikz-dotgrids to find on the web. But I have no idea of how to increase the dot size.



I think I would need the number of dots per row, the start and the end size of dots and the distance between them. But I have no clue how to combine these parameters to a nice dot grid.

            +0, I cant upvote more times for that fast marmot, I hope you can not think of an animation with a spiral that would hurt much more my eyes.

          • Well, I also can't upvote twice. Too bad. Do you have an algorithm for that or do you do it brute force? In the first case I'd be more than happy to ask a question such that you get more reputation points. ;-)

            As I explain use two other plications, I have worked with LCD screens, so that's where that knowledge comes from, doing it directly in latex would depend on whether there is a command that allows rescaling the image to certain pixels and obtain the color and luminosity values of the pixel, but I do not know, a lot of complication for things that come out when you do them for fun.

          • Well, I also can't upvote twice. Too bad. Do you have an algorithm for that or do you do it brute force? In the first case I'd be more than happy to ask a question such that you get more reputation points. ;-)

            As I explain use two other plications, I have worked with LCD screens, so that's where that knowledge comes from, doing it directly in latex would depend on whether there is a command that allows rescaling the image to certain pixels and obtain the color and luminosity values of the pixel, but I do not know, a lot of complication for things that come out when you do them for fun.

          • Well, I also can't upvote twice. Too bad. Do you have an algorithm for that or do you do it brute force? In the first case I'd be more than happy to ask a question such that you get more reputation points. ;-)

            As I explain use two other plications, I have worked with LCD screens, so that's where that knowledge comes from, doing it directly in latex would depend on whether there is a command that allows rescaling the image to certain pixels and obtain the color and luminosity values of the pixel, but I do not know, a lot of complication for things that come out when you do them for fun.

          • Well, I also can't upvote twice. Too bad. Do you have an algorithm for that or do you do it brute force? In the first case I'd be more than happy to ask a question such that you get more reputation points. ;-)

            As I explain use two other plications, I have worked with LCD screens, so that's where that knowledge comes from, doing it directly in latex would depend on whether there is a command that allows rescaling the image to certain pixels and obtain the color and luminosity values of the pixel, but I do not know, a lot of complication for things that come out when you do them for fun.

For the last 10-11 months, I am working in a research industry in France where my task is to debug C++ spaghetti code written over a period of several years by my current supervisor. It is a team of 2: just I and my supervisor. Diurnally, I am posed with a "bug of the day" to get out of this C++ code. My supervisor generally gives me about 15-30 minutes to solve it and then accosts me about whether or not the task is completed and then rinses and repeats this until the end of the day.

          Confectionery

          Prepared foods made with a lot of sugar or other cabohydrates "Sweetmeat" redirects here. For the racehorse, see Sweetmeat (horse). Not to be confused with Sweetbread. This Kransekake is a traditional Scandinavian baker's confection. Confectionery is the art of making confections , which are food items that are rich in sugar and carbohydrates. Exact definitions are difficult. [1] In general, though, confectionery is divided into two broad and somewhat overlapping categories, bakers' confections and sugar confections. [2] Bakers' confectionery, also called flour confections , includes principally sweet pastries, cakes, and similar baked goods. Sugar confectionery includes candies ( sweets in British English), candied nuts, chocolates, chewing gum, bubble gum, pastillage, and other confections that are made primarily of sugar. In some cases, chocolate confections (confections made of chocolate) are treated as a separate category, as are sugar-free versions of
