Grāmatu veikals

Pēdējā mēneša laikā, aktīvi strādāju pie jauna projekta - grāmatu internetveikala - izstrādes. Īstenībā, tas vairāk ir interfeiss kādam citam veikalam, nekā veikals kā tāds. Es to sauktu par skatlogu, katalogu, kas tev ļauj šķirstīt lapas, meklēt, apskatīt, katrā gadījumā, tikko vēlēsies iegādāties, tiksi nosūtīts uz citu vietni.

Daudz šķēršļu, ko pārvarēt, daudz faktoru, kas jāņem vērā, datu kešošana, dinamiskā ielāde, meklēšana, u.c. iespējas. Grāmatas tiek ielādētas no amērikas, tāpēc ir zināmas aizkaves, papildus tam, tās ir vairāki miljoni un API ir diezgan “stīvs”. Nu neko, cīnos, veidoju dinamisku un kofigurējamu vidi, kuru varēšu izmantot vēl diviem citiem veikaliem, kas jau stāv rindā uz izstrādi.

Grafiki un shēmas, bez zīmēšanas

Viens no lielākajiem dārgakmeņiem HTML5 maisiņā, ir Canvas, kura iespējas vairums vēl nav aptvēris. Kaut gan SVG tipa grafika nav nekas jauns, HTML5 Canvas dod vēl plašākas iespējas, kas ļauj interaktīvi iedarboties uz tās saturu. Lūk arī viens no pielietojuma veidiem: grafiku un shēmu zīmēšana, vadoties pēc sintakses.

Art & fear: observations on the perils (and rewards) of artmaking

“This is a book about making art. Ordinary art. Ordinary art means something like: all art not made by Mozart. After all, art is rarely made by Mozart-like people; essentially-statistically speaking-there aren’t any people like that. Geniuses get made once-a-century or so, yet good art gets made all the time, so to equate the making of art with the workings of genius removes this intimately human activity to a strangely unreachable and unknowable place. For all practical purposes making art can be examined in great detail without ever getting entangled in the very remote problems of genius.” —from the Introduction Art & Fear explores the way art gets made, the reasons it often doesn’t get made, and the nature of the difficulties that cause so many artists to give up along the way. The book’s co-authors, David Bayles and Ted Orland, are themselves both working artists, grappling daily with the problems of making art in the real world. Their insights and observations, drawn from personal experience, provide an incisive view into the world of art as it is expeienced by artmakers themselves. This is not your typical self-help book. This is a book written by artists, for artists — it’s about what it feels like when artists sit down at their easel or keyboard, in their studio or performance space, trying to do the work they need to do. First published in 1994, Art & Fear quickly became an underground classic. Word-of-mouth response alone-now enhanced by internet posting-has placed it among the best-selling books on artmaking and creativity nationally. Art & Fear has attracted a remarkably diverse audience, ranging from beginning to accomplished artists in every medium, and including an exceptional concentration among students and teachers. The original Capra Press edition of Art & Fear sold 80,000 copies. An excerpt: Today, more than it was however many years ago, art is hard because you have to keep after it so consistently. On so many different fronts. For so little external reward. Artists become veteran artists only by making peace not just with themselves, but with a huge range of issues. You have to find your work…
