遭黑客攻擊，美國最大燃油管道癱瘓！多州進入緊急狀態(tài):該公司聲明稱，此次網絡攻擊涉及使用勒索軟件，公司自7日起已主動切斷部分系統(tǒng)網絡，試圖遏制威脅，這導致所有管道運營暫停，部分it系統(tǒng)受到影響。
據(jù)悉，在這次的網絡攻擊中，黑客darkside通過安裝非法勒索軟件，控制了colonial pipeline的計算機系統(tǒng)或數(shù)據(jù)系統(tǒng)，并要求支付大筆贖金才能重新獲得訪問權限。
相關資料顯示，colonial pipeline運營的這條管道系統(tǒng)全長8851公里，并且精煉能源輸送體系非常龐大，將墨西哥灣沿岸地區(qū)的煉油廠與美國東部和南部相連。
管道每天運送超過250萬桶燃料，是亞特蘭大、華盛頓、紐約等地的汽油、柴油和航空燃料主要來源，同時也為這些地區(qū)的幾家大型國際機場服務，更承擔著美國東海岸45%的燃油供應。
不過這依然是一個嚴重的問題，石油價格信息服務部能源分析全球負責人tom kloza說。“它可能使整個國家陷入困境，因為這是該國從墨西哥灣沿岸向紐約輸送燃料的頸動脈?！?br>
pue指標能準確衡量數(shù)據(jù)中心能效嗎？-關于poe的設想-孫長青:pue指標能準確衡量數(shù)據(jù)中心能效嗎？
直至被各地政府部門將之上升到戰(zhàn)略高度，比如，北京、上海、深圳都先后出臺政策限定了本地pue的上限值，強迫數(shù)據(jù)中心在pue節(jié)能上下功夫。
1、數(shù)據(jù)中心pue的局限 pue的降低，需要對系統(tǒng)架構及制冷方案追加大量投資，其初投資的費用，與由此帶來的pue值的降低，到底在財務上是否劃算，還是未知數(shù)。
在各種發(fā)電方式中，除太陽能白天發(fā)電量大而夜間少而存在晝夜差異外，其他發(fā)電方式均與一天內的時間變化無關。由上面統(tǒng)計數(shù)字可知，太陽能發(fā)電占比極小，可忽略不計。
為了平衡用電負荷，高峰的時候盡量減少用電，降低電網負荷，用電低谷的時候鼓勵大家多用電，使得電網的用電負荷不出現(xiàn)極大幅度的下降，全國各地都進行了運用價格信號引導電力削峰填谷，利用峰谷電價差、輔助服務補償?shù)仁袌龌瘷C制
亞馬遜人臉識別系統(tǒng)再“犯錯”，國內“學友八殺”后又有“神探” 立功了:亞馬遜最近也面臨著同樣的壓力，7 月 26 日，北加州的美國公民自由聯(lián)盟（aclu）再次“找茬”亞馬遜的人臉識別系統(tǒng)。
aclu 稱，他們在測試 rekognition 的新系統(tǒng)時，掃描了所有 535 名國會議員的面孔，但與 25,000 張警方公開的犯罪嫌疑人照片進行匹配時，該系統(tǒng)錯誤地將 28 個國會議員與犯罪嫌疑人的照片進行了配對
最近，阿里城市大腦中的“天鷹”系統(tǒng)也立功了。
據(jù)澎湃新聞報道，今年 5 月下旬，通過“天鷹”系統(tǒng)強大的全域感知與漸進式視頻搜索能力，衢州警方對一對夫妻經常行動地區(qū)的上百個攝像頭，通過實時目標檢測、提取嫌疑人的高維特征、多模態(tài)數(shù)據(jù)時空碰撞計算等 ai
這樣的案例還有很多，4 月份，一位患有阿爾茨海默癥的 80 歲衢州老人走丟，但“天鷹”系統(tǒng)在 15 分鐘就監(jiān)控錄像里找到這位老人。同期，在一起電瓶車被盜事件中，該系統(tǒng)也只用了幾分鐘就迅速找到。
外媒說中國ai 5年內超越美國主導全球，我們該高興還是臉紅？:外媒稱，在東、西方的科技創(chuàng)新大戰(zhàn)中，人工智能(ai)目前成為前沿陣地，而中國在該領域的影響力正在提升。人工智能被視為開啟大數(shù)據(jù)和物聯(lián)網的關鍵。
眾所周知，許多早期的人工智能研究主要來自美國市場。在奧巴馬執(zhí)政的最后幾個月，美國政府發(fā)布了兩份報告，指出美國已不再是全球人工智能創(chuàng)新無可爭議的領先者。
相反，中國已經成為該領域的主要競爭對手，并對美國的地位構成了威脅。這兩份報告呼吁美國政府加大在機器學習領域的投資，強化政府與科技公司的合作，以開啟人工智能的巨大潛力。
雖然如此，今年5月對1268位科技公司創(chuàng)始人、ceo、投資者和研發(fā)人員的調查結果顯示，美國政府遠遠沒有為人工智能的未來影響做好準備。
更令人擔憂的是，雖然奧巴馬政府曾承諾增加人工智能開支，但特朗普政府卻提議，將美國國家科學基金會(nsf)對人工智能研發(fā)項目的投資削減10%。相比之下，中國對美國的人工智能創(chuàng)業(yè)市場卻十分感興趣。

在js代碼中獲取html下拉列表(#pro,#city)的代碼如下：
代碼語言：javascript
復制
var?pro=document.getelementbyid("pro");
var?city=document.getelementbyid("city");
js初始化#pro下拉列表：
代碼語言：javascript
復制
for?(var?i?=?0;?i?<?province.length;?i++)
????pro.add(new?option(province[i]));
js實現(xiàn)當點擊一級菜單（省份）時，二級菜單（城市）顯示對應城市列表信息：
代碼語言：javascript
復制
//獲取點擊的省份的下標
function?getindex(){
??for(var?i=0;i<province.length;i++)
????if(province[i]==pro.value)
??????return?i;
}
//根據(jù)獲取的省份下標，更改二級列表為對應下標的城市列表，此即二級聯(lián)動
function?addcity(e){
????var?index=getindex();
????e.options.length=0;
????for?(var?i?=?0;?i?<?city[index].length;?i++)
????????e.add(new?option(city[index][i]));
}
二級聯(lián)動的應用在日常code中常會遇到，簡單的說就是集合映射的問題。
假設有兩個數(shù)組a[],b[]
我們設置index標識量，
y=a[index]，y與index一一對應
g=b[index]，g與index也一一對應
這樣當更改y的值時，index隨之改變，也就改變了g的值，使得y與g一一對應，此即二級聯(lián)動的實現(xiàn)原理。
“國資云”將使云計算行業(yè)洗牌？:一、國資云的推廣預示著黨政及國企未來將堅持私有云技術路線。從天津、四川等省市國資云平臺的建設方式來看，未來黨政及國企部門的業(yè)務系統(tǒng)上云將堅持私有云的技術路線，由此可能對未來國內云計算市場帶來深遠影響。
iaas層是存儲數(shù)據(jù)的核心，國資云平臺將運行在具備國資背景、滿足等保二級要求的idc機房之上，各省市政府將通過新建或加強對現(xiàn)存idc機房資源的投資力度來強化對iaas層和數(shù)據(jù)的掌控，如浙江省在今年3月啟動國資云項目建設
，囊括云安全、oa、郵件、erp等各個通用化程度較高的應用環(huán)節(jié)，iaas層和paas層的基礎軟件廠商也將迎來更開放的發(fā)展環(huán)境，包括操作系統(tǒng)、數(shù)據(jù)庫、中間件等環(huán)節(jié)。
除去堅持私有云的路線以外，此次國資云建設明確要求把各企業(yè)自有的安全性不滿足等保二級要求的機房逐步遷移至國資云機房，符合等保二級及以上要求的機房及業(yè)務系統(tǒng)則需要與國資云平臺實現(xiàn)對接（尚不具備上云條件的系統(tǒng)可報備暫時不對接
如果“國資云”成為各地政府推行的樣本，對于提供“整體解決”方案的頭部云服務廠商來說，短期內確實形成了一定壓力。換言之，以前國企分別采購，現(xiàn)在如果國資云統(tǒng)一采購，那么對云服務產品的需求也會有新的變化。
谷歌劇變：李飛飛李佳離職后，現(xiàn)在輪到云ceo出局:2016年deepmind初露鋒芒，當時格林想和deepmind建立合作關系，在谷歌云的服務里標注“由deepmind提供支持”。
戴安·布萊恩特（diane bryant），前任英特爾數(shù)據(jù)中心業(yè)務負責人，被認為是英特爾三大高管之一，柯再奇離職后英特爾ceo的有力競爭者之一。去年11月，布萊恩特加入谷歌云，出任coo。
她在英特爾干了25年，在谷歌云才干了幾個月。而格林現(xiàn)在也要出局了。說一千道一萬，還是谷歌云的業(yè)務沒有起色。難堪大任谷歌云離職卸任之際，黛安·格林如何評價自己的是非功過？
第二，谷歌云建立了一個統(tǒng)一的業(yè)務線，將銷售、營銷、谷歌云平臺和谷歌應用g套件都整合到了谷歌云中。
對軍事工作的強烈反對，促使了谷歌對人工智能系統(tǒng)的使用有了更加嚴格的限制，這在實質上限制了云計算部門潛在的客戶基礎。之后，谷歌還退出了高達100億美元的軍用云計算合同競標。?
如何將cdn域名流量切換到ipv6？:導語 | 2020年末，很多門戶網站二級、三級鏈接的ipv6濃度要求達到85%以上。cdn業(yè)務切換到ipv6可能是最近很多互聯(lián)網公司在做的事情，那么如何能夠快速又穩(wěn)定的將業(yè)務切換到ipv6呢？
本地dns服務器將解析請求發(fā)送到騰訊云cdn全球調度體系，解析出最佳的cdn節(jié)點對應ipv6地址；4.
假設騰訊云提供的甘肅電信cdn測試節(jié)點地址為240e:935:a11:11c:30::，那么windows系統(tǒng)可以針對域名abc.test1.com綁定host為甘肅電信cdn節(jié)點240e:935:a11
并且最好選擇單個省份+單運營商進行小規(guī)?；叶扔^察（例如abc.test1.com+甘肅+電信ipv6），切換后觀察30分鐘ipv6流量正常則可以繼續(xù)按以下列表進行灰度：abc.test1.com+甘肅+
切換ipv6后在控制臺觀察對應域名業(yè)務情況：圖片.png 小結：到此完整的一次cdn域名切換ipv6的工作就完成了，整個切換過程一定要注意以穩(wěn)定為主。
微軟總裁呼吁：ai刷臉，美國政府該管一管了:史密斯并未闡述具體原則，而是建議政府創(chuàng)建一個“兩黨和專家委員會”對該問題展開研究，并給出建議。
史密斯提出，該委員會應該考慮的一系列問題，包括在執(zhí)法部門或國家安全部門使用這項技術時可能對其進行的約束；通過各種標準避免種族歧視；在使用這項技術之前獲得人們的許可，尤其是在公共領域；對于可能被錯認的人給予法律保護
考慮到華盛頓目前的政治僵局，提議組建專家委員會是一種比較保險的方式，可以避免政府真的限制微軟或其他科技公司使用人臉識別技術。但微軟總裁稱，這種委員會過去10年曾經出現(xiàn)過28次，而且取得了一些成功。
廣泛使用人臉識別，好處顯而易見，可以在公共場所識別犯罪分子。當然，除了利用技術幫助政府監(jiān)管外，微軟總裁還表示，微軟及其他科技公司應該在使用這種技術時肩負更多責任。
“我更愿意讓這些參與者跟他們的員工、用戶和美國政府互動，共同思考科技的潛在使用方式，以及使用科技的過程中可能所帶來的風險?！?br>
