英文原文:
"Notes Synthetiques", by Paul Gauguin
From the manuscript, c. 1888
Excerpted from "Theories of Modern Art", by Herschel B. Chipp
"Painting is the most beautiful of all arts. In it, all sensations are condensed; contemplating it, everyone can create a story at the will of his imagination and-with a single glance-have his soul invaded by the most profound recollections; no effort of memory, everything is summed up in one instant. -A complete art which sums up all the others and completes them. -Like music, it acts on the soul through the intermediary of the senses: harmonious colors correspond to the harmonies of sounds. But in painting a unity is obtained which is not possible in music, where the accords follow one another, so that the judgment experiences a continuous fatigue if it wants to reunite the end with the beginning. The ear is actually a sense inferior to the eye. The hearing can only grasp a single sound at a time, whereas the sight takes in everything and simultaneously simplifies it at will.
"Like literature, the art of painting tells whatever it wishes, with the advantage that the reader immediately knows the prelude, the setting, and the ending. Literature and music require an effort of memory for the appreciation of the whole; the last named is the most incomplete and the least powerful of arts.
"You can dream freely when you listen to music as well as when looking at a painting. When you read a book, you are a slave of the author's thought. The author is obliged to address himself to the mind before he can impress the heart, and God knows how little power a reasoned sensation has. Sight alone produced an instantaneous impulse. But then, the men of letters alone are art-critics; they alone defend themselves before the public. Their introductions are always a justification of their work, as if really good work does not defend itself on its own.
"These gentlemen flutter about the world like bats which flap their wings in the twilight and whose dark mass appears to you in every direction; animals disquieted by their fate, their too heavy bodies preventing them from rising. Throw them a handkerchief full of sand and they will stupidly make a rush at it.
"One must listen to them judging all human works. God has created man after his own image which, obviously, is flattering for man. "This work pleases me and is done exactly the way I should have conceived it." All art criticism is like that: to agree with the public, to seek a work after one's own image. Yes, gentlemen of letters, you are incapable of criticizing a work of art, be it even a book. Because you are already corrupt judges; you have beforehand a ready-made idea-that of the man of letters-and have too high an opinion of your own thoughts to examine those of others. You do not like blue, therefore you condemn all blue paintings. If you are a sensitive and melancholy poet, you want all compositions to be in a minor key. -Such a one likes graciousness and must have everything that way. Another one likes gaiety and does not understand a sonata.
"it takes intelligence and knowledge in order to judge a book. To judge painting and music requires special sensations of nature besides intelligence and artistic science; in a word, one has to be a born artist, and few are chosen among all those who are called. Any idea can be formulated, but not so the sensation of the heart. What efforts are not needed to master fear or a moment of enthusiasm! Is not love often instantaneous and nearly always blind? And to say that thought is called spirit, whereas the instincts, the nerves, and the heart are part of matter. What irony!
"The vaguest, the most undefinable, the most varied is precisely matter. Thought is a slave of sensations. I have always wondered why one speaks of "noble instincts." . . .
"Above man is nature.
"Literature is human thought described by words.
"Whatever talent you may have in telling me how Othello appears, his heart devoured by jealousy, to kill Desdemona, my soul will never be as much impressed as when I have seen Othello with my own eyes entering the room, his forehead presaging the storm. That is why you need the stage to complement your work.
"You may describe a tempest with talent-you will never succeed in conveying to me the sensation of it.
"Instrumental music as well as numbers are based on a unit. The entire musical system derives from this principle, and the ear has become used to all these divisions. The unit is established through the means of an instrument, yet you may choose some other basis and the tones, half-tones, and quarter-tones will follow each other. Outside of these you will have dissonance. The eye is used less than the ear to perceive these dissonances, but then divisions [of color] are more numerous, and for further complication there are several units.
"On an instrument, you start from one tone. In painting you start from several. Thus, you begin with black and divide up to white-the first unit, the easiest and the most frequently used one, hence the best understood. But take as many units as there are colors in the rainbow, add those made up by composite colors, and you will reach a rather respectable number of units. What an accumulation of numbers, truly a Chinese puzzle! No wonder then that the colorist's science has been so little investigated by the painters and is so little understood by the public. Yet what richness of means to attain an intimate relationship with nature!
"They reprove our colors which we put [unmixed] side by side. In this domain we are perforce victorious, since we are powerfully helped by nature which does not proceed otherwise. A green next to a red does not produce a reddish brown, like the mixture [of pigments], but two vibrating tones. If you put chrome yellow next to this red, you have three tones complementing each other and augmenting the intensity of the first tone: the green. Replace the yellow by a blue, you will find three different tones, though still vibrating through one another. If instead of the blue you apply a violet, the result will be a single tone, but a composite one, belonging to the reds.
"The combinations are unlimited. The mixture of colors produces a dirty tone. Any color alone is a crudity and does not exist in nature. Colors exist only in an apparent rainbow, but how well rich nature took care to show them to you side by side in an established and unalterable order, as if each color was born out of another!
"Yet you have fewer means than nature, and you condemn yourself to renounce all those which it puts at your disposal. Will you ever have as much light as nature, as much heat as the sun? And you speak of exaggeration-but how can you exaggerate since you remain below nature?
"Ah! If you mean by exaggerated any badly balanced work, then you are right in that respect. But I must draw your attention to the fact that, although your work may be timid and pale, it will be considered exaggerated if there is a mistake of harmony in it. Is there then a science of harmony ? Yes.
"In that respect the feeling of the colorist is exactly the natural harmony. Like singers, painters sometimes are out of tune, their eye has no harmony. Later there will be, through study, an entire method of harmony, unless people neglect it, as is done in the academies and most of the time also in studios. Indeed, the study of painting has been divided into two categories. One learns to draw first and then to paint, which means that one applies color within a pre-established contour, not unlike a statue that is painted after it is finished. I must admit that until now I have understood only one thing about this practice, namely that color is nothing but an accessory. I 'Sir, you must draw properly before painting"-this is said in a pedantic manner; but then, all great stupidities are said that way.
"Does one wear shoes instead of gloves? Can you really make me believe that drawing does not derive from color, and vice-versa? To prove this, I commit myself to reduce or enlarge one and the same drawing, according to the color with which I fill it up. Try to draw a head by Rembrandt in his exact proportions and then put on the colors of Rubens-you will see what misshapen product you derive, while at the same time the colors will have become unharmonious.
"During the last hundred years large amounts have been spent for the propagation of drawing and the number of painters is increasing, yet no real progress has been made. Who are the painters we admire at the present? All those who reproved the schools, all those who drew their science from the personal observation of nature. Not one ..."

我能容忍自己每個字都是錯的,但是卻不能容忍其中任何一個字不是真誠的。
祝好運(yùn)~~
想要進(jìn)入互聯(lián)網(wǎng)行業(yè),首先得搞清楚互聯(lián)網(wǎng)行業(yè)中有哪些崗位,這些崗位是做什么的,再去關(guān)注選擇一個崗位、一個方向。
一、互聯(lián)網(wǎng)中的崗位。
一般,公司越大崗位越完善,我們選擇阿里巴巴的招聘頁,去看看大型互聯(lián)網(wǎng)公司都有哪些崗位。
圖片來源:阿里官網(wǎng) 招聘頁
從圖片可以得出,除開一個公司的基礎(chǔ)職能崗位(行政、財務(wù)、法務(wù)等),互聯(lián)網(wǎng)崗位大的方向可以分為技術(shù)、設(shè)計(jì)、產(chǎn)品、運(yùn)營。
1、技術(shù):
技術(shù)崗中包含前端、開發(fā)、運(yùn)維、質(zhì)量保證、數(shù)據(jù)、算法、地圖(GIS)等。
2、設(shè)計(jì):
設(shè)計(jì)崗有交互設(shè)計(jì)、視覺設(shè)計(jì)、用戶體驗(yàn)與研究。
? ?
3、產(chǎn)品:
產(chǎn)品針對不同業(yè)務(wù)方向,對產(chǎn)品也會有所區(qū)分。
4、運(yùn)營:
運(yùn)營也和產(chǎn)品一樣,公司的業(yè)務(wù)不同,運(yùn)營的方向、內(nèi)容、方式也會不同。? ? ? ? ?
知道了這些崗位,那這些崗位在具體的工作是什么呢?一個項(xiàng)目的從無到有,前期的工作就不細(xì)述了,項(xiàng)目正式開始大概的流程:
(1)項(xiàng)目負(fù)責(zé)人:制定項(xiàng)目計(jì)劃。
(2)需求/產(chǎn)品:據(jù)用戶訴求,分析產(chǎn)品規(guī)劃,輸出需求文檔?;蛘呤怯脩舴治觯a(chǎn)品定位,輸出產(chǎn)品需求。
(3)需求/產(chǎn)品:依據(jù)初步的原型圖和需求文檔,對開發(fā)、測試澄清需求。或者是產(chǎn)品依據(jù)需求輸出線框圖。
(4)設(shè)計(jì):根據(jù)需求,交互設(shè)計(jì)師設(shè)計(jì)原型圖,輸出交互稿;UI設(shè)計(jì)師輸出UI稿。交互和UI評審。
(5)開發(fā):依據(jù)迭代要求和開發(fā)計(jì)劃,開發(fā)對應(yīng)功能模塊。
(6)測試:輸出測試方案,依據(jù)測試計(jì)劃和開發(fā)給出的轉(zhuǎn)測范圍,測試對應(yīng)功能。
(7)運(yùn)維:迭代開發(fā)完成后,項(xiàng)目交付,進(jìn)入運(yùn)維期。
依據(jù)以上流程,需求(產(chǎn)品崗)需要參與項(xiàng)目前期產(chǎn)品定位、需求整理的工作,同時在整個項(xiàng)目周期需要依據(jù)項(xiàng)目計(jì)劃,給項(xiàng)目組人員澄清需求。依據(jù)測試反饋、用戶反饋、活動周期去調(diào)整產(chǎn)品需求,需求(產(chǎn)品崗)孕育產(chǎn)品。
在阿里的招聘頁中,設(shè)計(jì)崗包含交互設(shè)計(jì)、視覺設(shè)計(jì)以及用戶體驗(yàn)與研究。設(shè)計(jì)依據(jù)產(chǎn)品提出的需求去做產(chǎn)品的交互設(shè)計(jì)、視覺設(shè)計(jì),讓產(chǎn)品生動形象。
開發(fā)人員依據(jù)需求和設(shè)計(jì),賦予產(chǎn)品真正的生命,讓產(chǎn)品活起來。測試是保證產(chǎn)品質(zhì)量,讓產(chǎn)品更完美。一個成熟的產(chǎn)品上線后,運(yùn)維人員去維護(hù)產(chǎn)品的正常使用,運(yùn)營人員提高產(chǎn)品的曝光,吸引大家使用該產(chǎn)品。
二、簡單介紹了互聯(lián)網(wǎng)中的崗位,那什么崗位適合零基礎(chǔ)的人呢?
由于市場需求量大,薪資待遇高,所以越來越多的人想要加入互聯(lián)網(wǎng)行業(yè),針對零基礎(chǔ)想要轉(zhuǎn)行的小伙伴到底選擇哪個方向去學(xué)習(xí)才能快速入行呢?
這個答案肯定不統(tǒng)一,因?yàn)槊總€人的興趣、性格、行業(yè)背景不同,選擇、適合的方向也不同。我們?nèi)チ牧拿總€方向需要的能力與發(fā)展,再結(jié)合你自己的情況選擇一個方向深入發(fā)展。
1、技術(shù):
技術(shù)崗一般分為開發(fā)、測試、運(yùn)維,開發(fā)針對不同的語言,有不同的方向,如java、C++、Python等。不同的職責(zé)分為前端開發(fā)、后臺、手機(jī)應(yīng)用等,不同的業(yè)務(wù)方向分為區(qū)塊鏈、人工智能、C端、B端、移動端等。
測試又依據(jù)不同的測試方向,分為功能測試、性能測試、安全測試、自動化測試等。? ? ? ? ? ?
針對這些方向,如果你是零基礎(chǔ)而且對編碼很感興趣,可以嘗試前端開發(fā)、java開發(fā)、測試,原因有以下幾點(diǎn):
1、前端開發(fā)零基礎(chǔ)好入門,上手快可以立馬看到學(xué)習(xí)效果,可以大大提高學(xué)習(xí)興趣。但是并不是說前端沒有技術(shù)含量,我們不僅需要學(xué)習(xí)前端基礎(chǔ),還需要學(xué)習(xí)vue.js、react.js、react-native和Flutter等主流框架,并擴(kuò)展three.js、typescript等等技術(shù),深挖、剖析框架原理。甚至了解后端的知識,在工作中才能減少溝通成本。
2、Java作為一門面向?qū)ο缶幊陶Z言,是全球主流的編程語言之一。Java技術(shù)具有卓越的通用性、簡單性、安全性、高效性、健壯性、多線程、動態(tài)性、平臺獨(dú)立與移植性等特點(diǎn),可以用于編寫Web 應(yīng)用程序、桌面應(yīng)用程序、分布式系統(tǒng)和嵌入式系統(tǒng)應(yīng)用程序等。相關(guān)調(diào)查顯示,在各種編程語言中,Java使用者比例很高,達(dá)40%以上!
3、為了保證軟件在出廠時的"健康狀態(tài)",幾乎所有的IT企業(yè)在軟件產(chǎn)品發(fā)布前都需要大量的質(zhì)量控制工作。你可能會說,為什么要對編碼感興趣才建議去學(xué)測試,測試不就是點(diǎn)點(diǎn)點(diǎn)嗎?你錯了,點(diǎn)點(diǎn)點(diǎn)的工作已經(jīng)不能滿足企業(yè)對測試的需求了,現(xiàn)在市場上更傾向于有開發(fā)能力的測試。比如在測試工作中,我們可能會需要寫測試腳本、測試工具,所以這些都需要測試工程師具備一定的編碼能力。所以如果對測試感興趣一定也要學(xué)習(xí)編碼,具備一定的編碼能力哦。
2、設(shè)計(jì):
互聯(lián)網(wǎng)中的設(shè)計(jì)分為視覺設(shè)計(jì)和交互設(shè)計(jì),視覺設(shè)計(jì)又會依據(jù)公司業(yè)務(wù)、項(xiàng)目分為Web網(wǎng)頁設(shè)計(jì)、電商設(shè)計(jì)、移動端設(shè)計(jì)、運(yùn)營插畫設(shè)計(jì)等。? ? ? ? ? ?
交互設(shè)計(jì)是努力去創(chuàng)造和建立的是人與產(chǎn)品及服務(wù)之間有意義的關(guān)系,而視覺設(shè)計(jì)主要是讓產(chǎn)品富有靈魂,生動有美感。由于大多數(shù)不了解互聯(lián)網(wǎng)的人,大概聽得最多的崗位是開發(fā)和測試,那我們就一起來了解一下UI設(shè)計(jì)。
UI(User Interface),中文名“用戶界面”。Ps:(百度解釋)UI是指對軟件的人機(jī)交互、操作邏輯、界面美觀的整體設(shè)計(jì)。
通俗來說,大家生活中的手機(jī)和電腦上使用的各種App、網(wǎng)頁軟件等產(chǎn)品的原型設(shè)計(jì)都來自于UI。
如果你覺得開發(fā)編碼太累,測試太枯燥,可以嘗試了解一下UI設(shè)計(jì)。也許你會問沒有繪畫基礎(chǔ)也可以學(xué)習(xí)UI設(shè)計(jì)嗎?
答案是肯定是可以的,市面上大多數(shù)的UI設(shè)計(jì)并非科班專業(yè)出生,通過不斷的學(xué)習(xí)和積累,也可以具備UI設(shè)計(jì)的相關(guān)專業(yè)技能。
那UI設(shè)計(jì)的前景是否和技術(shù)崗一樣好呢?
我們將UI設(shè)計(jì)、前端開發(fā)、軟件測試這三個崗位來做對比,可以看出UI設(shè)計(jì)也是跟著技術(shù)崗的市場需求在有浮動的變化。最近幾個月,UI設(shè)計(jì)的市場需求還高于技術(shù)崗,所以說UI市場并未飽和,還有很大的市場需求。
圖片來源:職友集
說明:曲線越向上代表市場需求量越大,就業(yè)情況越好。反之,代表該類職位需求量較少。該數(shù)據(jù)由各地招聘網(wǎng)站統(tǒng)計(jì)而來,可能因抓取系統(tǒng)穩(wěn)定性等因素而致使數(shù)據(jù)偏離客觀實(shí)情,僅供參考。
從市場招聘條件可以得出UI設(shè)計(jì)的薪資待遇在5000以上的占多數(shù),全國UI設(shè)計(jì)的平均薪資是在一萬左右,UI設(shè)計(jì)對于學(xué)歷也沒有超級高的要求,所以普通學(xué)歷通過UI設(shè)計(jì)進(jìn)入大廠的幾率更高。? ? ? ? ? ?
圖片來源:職友集
圖片來源:職友集
近幾年UI工資也是在穩(wěn)步上升,入行UI設(shè)計(jì),隨著工作經(jīng)驗(yàn)的積累,設(shè)計(jì)能力的提升,對應(yīng)的薪資待遇也會增長。再者,當(dāng)經(jīng)驗(yàn)豐富后還可以利用工作之余兼職,這也是一筆不錯的收入。
圖片來源:職友集
阿里巴巴資深總監(jiān)楊光曾表示:無論是魯班,還是未來升級的人工智能都不可能取代設(shè)計(jì)師,機(jī)器人只是幫助設(shè)計(jì)師解決重復(fù)性的工作,重塑整個設(shè)計(jì)生態(tài),而真正的“設(shè)計(jì)師”,反而會越來越值錢。
綜上所述,想要不被社會淘汰,最好讓人無法取代。入行互聯(lián)網(wǎng),選擇UI設(shè)計(jì)讓你既有技術(shù)又有發(fā)展。如果對UI設(shè)計(jì)感興趣,選擇UI讓興趣和夢想齊飛。
3、產(chǎn)品:
當(dāng)然也有很多小伙伴對產(chǎn)品經(jīng)理這個職位很感興趣,難道是因?yàn)榻?jīng)理這個頭銜聽起來很拉風(fēng)。那我們又來了解互聯(lián)網(wǎng)行業(yè)中的產(chǎn)品經(jīng)理。
人人都是產(chǎn)品經(jīng)理,但是真的每個人都能做產(chǎn)品經(jīng)理嗎?產(chǎn)品經(jīng)理會伴隨一個產(chǎn)品走完全部的生命周期,他需要和開發(fā)、設(shè)計(jì)、測試、運(yùn)營等團(tuán)隊(duì),及上下游緊密合作,對項(xiàng)目進(jìn)行風(fēng)險把控和資源協(xié)調(diào),推進(jìn)達(dá)成產(chǎn)品目標(biāo)。
雖然看似產(chǎn)品經(jīng)理不需要技術(shù),但是沒有技術(shù)背景你如何和技術(shù)人員溝通,如何把控進(jìn)度與風(fēng)險,所以產(chǎn)品經(jīng)理特別考驗(yàn)一個人的綜合素質(zhì),就不建議零基礎(chǔ)的小伙伴通過產(chǎn)品經(jīng)理入行互聯(lián)網(wǎng)了。你可以通過技術(shù)入行,再轉(zhuǎn)到產(chǎn)品崗,有了技術(shù)背景,對你的產(chǎn)品經(jīng)理的職業(yè)發(fā)展有很大幫助哦。
4、運(yùn)營:
運(yùn)營就是對運(yùn)營過程的計(jì)劃、組織、實(shí)施和控制,是與產(chǎn)品生產(chǎn)和服務(wù)創(chuàng)造密切相關(guān)的各項(xiàng)管理工作的總稱。而互聯(lián)網(wǎng)運(yùn)營就是要利用一切資源與策略去吸引用戶,增加用戶粘性。
大多數(shù)的人會說,運(yùn)營崗位門檻低,沒有太多技術(shù)含量。對于運(yùn)營來說,因?yàn)闆]有固定的概念和標(biāo)準(zhǔn)的工作定義,不同的產(chǎn)品、不同的平臺所采取的方式方法不一樣,所以運(yùn)營工作靈活,方式多變,需要順應(yīng)變化。由于回答中有很多關(guān)于運(yùn)營崗位的回答,在這里我就不再對運(yùn)營崗位進(jìn)行詳細(xì)說明了。
其實(shí)互聯(lián)網(wǎng)行業(yè)中的崗位很多,根據(jù)自己的興趣和背景去選擇合適的方向,但是零基礎(chǔ)找到工作肯定不現(xiàn)實(shí)。因?yàn)槠髽I(yè)不是學(xué)校,不會傳授技術(shù)給零經(jīng)驗(yàn)、零基礎(chǔ)的人,所以你一定得具備勝任崗位的能力,才有可能入行互聯(lián)網(wǎng)。零基礎(chǔ)、零經(jīng)驗(yàn)的小伙伴,大多數(shù)都會以初級人員的要求進(jìn)入行業(yè),所以想要入行,你至少得具備一定的技能和前提條件。
