① 亞馬遜程序員級別怎麼區分
首先,亞馬遜程序員級別一般分為以下幾個級別,初級工程師、中級工程師、高級工程師、資深工程師/架構師。
然後再分清他們的區別就可以了。
1、初級工程師
初級工程師主要是指剛畢業的,職場上的技術新人。通常這類人會有一定的專業理論知識,所以也能夠比較快的學習公司的常用框架、工具和開發技術。能夠在上級/導師的指導下,理解相關的業務知識。
能夠按照研發需求完成部分模塊和功能的開發,能夠在別人的指導下解決研發中遇到的問題
2中級工程師
中級工程師是大多數三到五年程序員所處的水平。中級工程師必須要能夠獨立承擔開發任務,並且能夠獨立負責某個模塊或小系統。
能夠根據自己的歷史經驗和學習能力,獨立解決日常工作中遇到的技術問題。
3、高級工程師
高級工程師,一般是混跡多年,且有一定技術積累的程序員,有一套自己的開發方法。對於高級工程師要求能快速的理解業務、夠獨立負責一個中大型系統,且在工作中需具備指導他人的能力,屬於團隊骨幹,在團隊中有一定的技術影響力。
4資深工程師/架構師
程序員到了資深的級別之後,其實在職業上可以分為兩個發展方向。
一個是繼續往技術深度上鑽研,在某個技術領域內有一定的深度和影響力,我們稱為資深工程師。
還有另一個方向就是往技術的廣度上發展,除自身技術線以外,對周邊相關技術也有一定的研究和理解,能夠站在更高的維度上去俯視項目里的技術結構,業務理解能力也很強,根據不同業務,設計出不同的技術方案,這一類我們稱為架構師。
② 流利說-L7-U2-P3 Learning
So I started my first job as a computer programmer in my very first year of college, basically , as a teenager.
因此,我第一份工作是一名計算機程序員,那是在我剛上大學的時候,總的來說是一名青少年。
Soon after I started working, writing software in a company,
我開始工作不久後,正在公司寫軟體,唯裂
a manager who worked at the company came down to where I was.
公司里的一名經理屈尊來到我工作的地方,
and he whispered to me," Can he tell if I'm lying?」
對我耳語,如果我在說謊它看得出來嗎?
There was nobody else in the room.
房間里沒有別人。
"Can who tell if you're lying? And why are we whispering?"
如果你在說謊,誰能看出來?還有,為什麼我們要耳語?
The manage pointed at the computer in the room. "Can he tell if I'm lying?"
那個經彎槐理指向房間里的電腦,說,「如果我在說謊,它看得出來嗎?」
Well, that manager was having an affair with the receptionist.
好吧,那名經理正和前台有曖昧。
And I was still a teenager.
而我還只是一名青少指鬧閉年。
So I whisper -shouted back to him," Yes, the computer can tell if you're lying."
我低喊著回答他,「是的,如果你說謊,這台電腦會看得出來。」
Well, I laughed, but actually , the laugh's on me.
好吧,我笑了。但其實,我是在笑自己。
Nowadays, there are computational systems that can suss out(弄清 認清 看清) emotional states and even lying from processing human faces.
現在,計算機系統可以通過分析人臉來識別人的情緒,甚至說謊。
Advertisers and even governments are very interested.
廣告商、甚至政府都對此非常感興趣。
I had become a computer programmer because I was one of those kids crazy about math and science.
我選擇成為一名電腦程序員,因為我就是那種痴迷於數學和科學的孩子之一。
But somewhere along the line I'd learned about nuclear weapons, and I'd gotten really concerned with the ethics of science. I was trouble.
但是有時沿著那條線,我喜歡了解核武器,我真的關心科學論理。我困惑了。
However, because of family circumstances, I also needed to start working as soon as possible.
然而,由於家庭原因,我也需要盡快找工作了。
So I thought to myself, hey, let me pick a technical field where I can get a job easily and where I don't have to deal with any troublesome questions of ethics.
因此,我心想,嘿,我還是找個容易找工作的技術領域,我不需要擔心麻煩的倫理問題。
So I picked computers.
所以,我選擇了計算機。
Well, hahaha! All the laughs are on me.
好吧,哈哈哈,我有多可笑。
Nowadays, computer scientists are building platforms that control what a billion people see everyday.
現在,計算機科學家正在建造一個可以控制十億人每天看見的平台。
They're developing cars that could decide who to run over.
他們開發能夠決定誰來開動的汽車。
They're even building machines, weapons, that might kill human beings in war.
他們甚至建造那些可能在戰爭中殺死人類的機器,武器。
It's ethics all the way down.
各方論理都降低了。
1. Why does Yufekci mention the conversation with her manager?
...to show people's concern about the power of computers.
2. The idom " Somewhere along the line" means...
...at some point ring a process.
3.排序
1)Nowadays, computer scientists are building platforms that control what a billion people see everyday.
2)They're developing cars that could decide who to run over.
3)They're even building machines, weapons, that might kill human beings in war.
4)It's ethics all the way down.
4. 聽 復述
Nowadays, computer scientists are building platforms that control what a billion people see everyday.
③ R語言 !=是什麼意思
發生比來判定因變數的類別。在這里我們引入概率的概念,把事件發生定義為Y=1,事件未發生定義為Y=0,那麼事件發生的概率為p,事件未發生的概率為1-p,把p看成x的線性函數;
