① BitXHub最近有什麼新動態嗎

BitXHub是趣鏈科技自主研發的開源跨鏈技術平台，是區塊鏈互聯互通、價值互連的關鍵技術支撐。聽說BitXHub DID已成功加入全球去中心化身份聯盟DIF（Decentralized Identity Foundation）的Universal Resolver，並成功取得DIF框架下名為bitxhub的method-name。就是說BitXHub項目成為了首個鏈原生支持W3C標准DID協議的跨鏈平台。好的，如果有需要，隨時歡迎你的詢問。

② 現在的婚戀交友網站靠譜嗎會有騙子嗎

有人說過，中國人厲害的地方，就是把什麼都做成生意。其實這話不對，是任何事本身就是生意，只是你去不去做的問題。當我們看到一個社會的改變其實是從一樁生意開始的時候，恐怕更能理解為什麼我們這個社會有了如此深刻的變化。那麼成都婚介機構開辦了網路婚戀交友網站靠譜嗎？

在一個婚介機構開張的13年後，網路開始有了交友的網站，更多的社會關系被重新進行了整合。從那時候開始，一次更深刻的社會關系的鼎革又走了13年，相信任何人都會說，這些年我們的社會更加寬容、更加能接受新的生活方式了。這方面的進步，都是從一個婚介機構開始的。

「那個時候，人們熱衷參加集體活動，又是組織給安排的，安全有保障」，成都資深婚戀專家王老師說，對於大齡青年來講，參加類似集體活動是非常時髦的事情。

但退休之後還想有自己的工作，專心來解決「找對象」問題。王老師說，於是，2004年，成都的一家退休機關幹部舉辦的婚介成立，由退休機關幹部坐鎮，隸屬成都市專門為單身的婚姻服務，並配備工作人員。

還有一位領導幹部的兒子來所里准備登記時，要求給他找一個處級幹部的女兒。婚介里沒讓他登記，而是對他進行思想教育，批評他「門當戶對」是世俗觀念，說得這位幹部子弟後來都不好意思公開他父親的名字。

其實現在看來經過這些年的發展婚介的市場越來越多，以城市居多。婚介所的生意也很紅火。現在僅成都市，年齡在35歲到50歲的單身男女就有50多萬人。單身男女持有效證件注冊為婚介所會員後，婚介所會根據他們的擇偶要求，從會員中介紹條件合適的人選與其認識。據業內人士透露，一些大的婚介所，有幾萬名到十幾萬名會員。但是都是通過實名認證，有些連婚戀網站都要求實名制管理。成都尊誠情緣負責人說。

④ QTUM-量子鏈是什麼

.
投資比特幣現在的收益也沒有那麼高啊。我所知道的這類理財產品都屬於高利貸，年化率高於24%的一般都不被國家保護。我所知道的，月盈利30%的都是一些傳銷騙局，例如BBT造幣機就是這樣。
當然，也許你會反駁我，因為你確實獲得了收益，但如果不讓你嘗到甜頭，你會投資更多的資金嗎，會去拉人頭嗎？這個可以去網路一下旁氏騙局。

⑤ 售前工程師要具備哪些技能和工具

• Word：大概只有售前這類文案人員才能體會到Word的博大精深；

• PPT：段位越高的售前，PPT做（講）的越好。

• Visio：常用於畫流程圖、網路架構圖；

• 思維導圖軟體，如MindMaster：幫助梳理工作、材料思路；

• Axure：主要是軟體售前使用，用於界面設計；

A. 馬斯洛需求層次理論

Maslow's Hierarchy of Needs

從對食物的需求過渡到互聯網信息科技時代

對健康、安全、娛樂、愛和價值

對知識產權保護等更高級的需要

1.Biological and physiological needs- air, food, drink, shelter, warmth, sex, sleep.

2.Safety needs- protection from elements, security, order, law, stability, freedom from fear.

3.Love and belongingness needs- friendship, intimacy, trust, and acceptance, receiving and giving affection and love. Affiliating, being part of a group (family, friends, work).

4.Esteem needs- (i) esteem for oneself (dignity, achievement, mastery, independence) and (ii) the desire for reputation or respect from others (e.g., status, prestige). The need for respect or reputation is most important for children and adolescents and precedes real self-esteem or dignity.

5.Cognitive needs- knowledge and understanding, curiosity, exploration, need for meaning and predictability.

6.Aesthetic needs- appreciation and search for beauty, balance, form, etc.

7.Self-actualization needs- realizing personal potential, self-fulfillment, seeking personal growth and peak experiences. A desire 「to become everything one is capable of becoming」.

8.Transcendence needs- A person is motivated by values which transcend beyond the personal self (e.g., mystical experiences and certain experiences with nature, aesthetic experiences, sexual experiences, service to others, the pursuit of science, religious faith, etc.).

B. 全球化與殖民主義：主流文化入侵

Post-colonialism & Cultural Imperialism

Impact on Global Communication

從互聯網到全球聯系的增強

從科技和文化霸權看帝國殖民

從創新發展到本土文化的逐漸模糊與喪失

宗教、語言、民俗的趨同

Cultural Imperialism: the extension of influence or dominance of one nation』s culture over others, through the exportation of cultural commodities.

Global communication: the communication practice occurring across national borders, social, political, and cultural divides. The need for global communication has increased e to the expanse of globalisation.

The World Systems Theory: an inter-regional and transnational division of labour with core, periphery, and semi-periphery countries.

In its conquest of Italy, the Roman Empire imposed Latin on the people of Etruria, replacing the Etruscan language, which ultimately led tothe demise of the language and other aspects of the Etruscan culture. Then, Latin was the lingua franca and today English isthe lingua franca of global communication

The expansion of the British Empire ring the eighteenth and nineteenth centuries: cultural form of imperialism, throughreligious proselytising, i.e. the imposition of Christianity on cultures with other religions.The British Empire also exerted its cultural power throughimposing ecational material on the colonies, promoting the empire through books and syllabuses, serving the interest of colonialism.

The assimilation of media:literature, film, television, Internet, and music.

US media and entertainment instries, like Hollywood and Disney, are able topenetrate the global market and export US-American cultural procts and values.

C. 資本主義、信息共享與互聯網

Capitalism and the Internet

資本主義剝削形式、人們工作方式的轉變

new way to exploit the working class

without having to work in factories

時長加長，無形的工作與生產

more time investment, longer exploitation

enhance possibilities to enjoy their work

give rise to a new proletarian identity

eventual confrontation with capital owner

Internet is just the development of past ways of entertainment, communication and knowledge (games, libraries, letters, books, etc.) which helped spread ecation and information throughout society andlower classes as they became more and more reachable and affordable, whilst also,especially in the case of entertainment, alienating people from their nature (workers- not in a bad connotation).

New technology hastranscended the standard capitalist business model.

Intangible, conceptual assets: a large part of corporate wealth, likeintellectual property, trademarks, patents and right. Microsoft is not valued principally in physical capital assets, as was the case with big corporations in the past. What Microsoft claims to own isideas, ideas that we all need to run factories and offices and to communicate with each other.

As Thomas Jefferson put it,passing light on to another candle does not diminish the light from your own. Jefferson thought this was a good enough reason whyideas should not be treated like coal, candles and other commodities, but should be allowed to circulate freely for the common good.

D. 科技創新和女權主義

Technology and Gender Gap

技術教育不足，科技行業需要卻鮮有女性

男性主導、敵意的工作環境，高離職率低薪

Women have been left out of the mainstream of recorded technological development. Technology, increasingly so in instrialized societies, is male.

A feminist perspective can help us move from a hard technology society to a soft technology future in which values such asharmony with nature, subjectivity, co-operation, and non-exploitationbecome integral to technological development.

In the 1980s, women made up a little under40 percent of computer-science graates.Since then, the gender gap has grown: Currently, less than 20 percent of computer-science graates are women. In the earliest days of programming, ring World War II, building computers was deemed a macho thing, and programming was thought to be for typists. Later, when personal computers began to appear in homes and offices, they were promoted as apastime -- for boys.Contemporary bro culture has done nothing to attack this bias.

School should expand thefemale facultyand make thecurriculummore inviting to talented students withlimited exposure to computer science: assign classes according to students' past programming experience -- to prevent long-time enthusiasts fromintimidating novices.

bloomberg.com/view/articles/2017-09-06/how-to-close-the-gender-gap-in-tech

The tech instry's gender imbalance is no secret – only 17% of technology specific jobs are held by women.Projects to counter the problem, from conferences to mentorship programmes, are becoming widespread but are usually aimed at women already embarking on careers.

From toys to language, teaching girls basic skills and busting gender myths from an early age could encourage more women into tech careers.
