reddit 與 4chan 在新聞網路上的獨特性

在「Study finds fringe communities on Reddit and 4chan have high influence on flow of alternative news to Twitter」這邊看到的:

After analyzing millions of posts containing mainstream and alternative news shared on Twitter, Reddit and 4chan, Jeremy Blackburn, Ph.D., and collaborators found that alt-right communities within 4chan, an image-based discussion forum where users are anonymous, and Reddit, a social news aggregator where users vote up or down on posts, have a surprisingly large influence on Twitter.

依照對 reddit4chan 的描述,這兩個媒體對 Twitter 的影響,會讓我聯想到在台灣 Ptt 對各新聞媒體的影響:Ptt 是很多新聞的起點?

"Based on our findings, these smaller, fringe communities on Reddit and 4chan serve as an incubation chamber for a lot of information," said Blackburn, assistant professor of computer science in the UAB College of Arts and Sciences. "The content and talking points are refined until they finally break free and make it to larger, more mainstream communities."

真的研究應該可以看出 Ptt 的影響力?

俄羅斯展現「錢要花在刀口上」的功力?

TechCrunch 這篇「Trump and Clinton spent $81M on US election Facebook ads, Russian agency $46K」講到 Facebook 目前階段所判斷出來,能夠識別是俄羅斯政府投入的資金,只有 USD$46K,相較於美國兩黨投入了 USD$81M 差了 1760 倍:

While there might have been other Russian disinformation groups, the IRA spent $46,000 on pre-election day Facebook ads compared to $81 million spent by Clinton and Trump together, discluding political action committees who could have spent even more than that on the campaigns’ behalf.

而俄羅斯投入的廣告散佈率超過 1.26 億的 Facebook 使用者,以及 2000 萬 Instagram 的使用者:

Facebook today said that the Russians still reached 126 million Facebook users, as well as 20 million Instagram users.

俄羅斯這團隊的水準真不賴... 只可惜大概沒辦法寫在 resume 上。

聽證會的資料可以從「Hearings」這邊看到。

Walmart 在賣場要導入機器人取代人類的工作了...

在「Walmart will soon have robots roaming the aisles in 50 stores」這邊看到 Walmart 要導入機器人取代人類的工作了,像是架上沒貨或是標籤錯誤或沒標的:

The robots go up and down the aisles, scanning for out-of-stock items, incorrect prices, and wrong or missing labels.

像是這樣的機器:

或是在掃描時更明顯的照片:

如果一直讓機器來換掉人類能做的事情,是不是有機會到後來就沒有工作需要做?如果當全世界都實行「無條件基本收入 (Unconditional Basic Income)」時,會不會愈來愈接近 Star Trek 裡面講到未來的經濟體系,沒有貨幣時情況?不曉得兩百年後會是什麼樣子...

強制 Facebook 的「時間軸」依照時間排序

TechCrunch 的「How I cured my tech fatigue by ditching feeds」這篇提到了 Social Network 成隱的問題:

Many people have deleted the Facebook app from their phone to avoid this mindless habit. “What’s going on in my feed?” they think. Then they scroll, scroll, scroll, get bored and close the app. Repeat this process every 30 minutes. Deleting the app is the best way to take a stance and say that Facebook is a waste of time.

砍掉 Facebook 是一個還不錯的方法,但如果還是有使用 Facebook 需求,就只好想辦法降低 Facebook 帶來的影響。其中我找的方法是強制切到 Most Recent 版本,降低 Facebook 演算法的介入。

昨天剛好在重新處理機器,發現之前用的那個 Google Chrome 套件不見了,只好找看看有沒有替代方案,後來翻到這個:「Facebook Most Recent News Feed」。

如果看裡面程式碼,其實做的事情很簡單,就是硬切過去:

chrome.webRequest.onBeforeRequest.addListener(
    function(info) {
        if (info.url === 'https://www.facebook.com/') {
            return {
                redirectUrl: 'https://www.facebook.com/?sk=h_chr'
            }
        }
    }, {
        urls: [
            "https://www.facebook.com/*"
        ],
        types: ["main_frame"]
    }, ["blocking"]
);

當然,如果能考慮整個移除的話也是不錯啦...

被告了就把證據滅掉... XD

這個好讚,在告知安全漏洞後還是不更新選舉用伺服器,於是就被告了,而在被告以後選舉單位就把證據給幹掉 XD:「Georgia election server wiped after lawsuit filed」。

The lawsuit, filed on July 3 by a diverse group of election reform advocates, aims to force Georgia to retire its antiquated and heavily criticized election technology. The server in question, which served as a statewide staging location for key election-related data, made national headlines in June after a security expert disclosed a gaping security hole that wasn’t fixed six months after he reported it to election authorities.

然後現在還找不到是誰下令幹掉的...

It’s not clear who ordered the server’s data irretrievably erased.

執政者用的方法都差不多...

紐約時報網站上 Tor 的 Hidden Service (i.e. Tor Onion Service)

紐約時報官方把整個站台放到 TorHidden Service 上了:「The New York Times is Now Available as a Tor Onion Service」。

而且也買了 SSL certficiate:

The address for our Onion Service is:
https://www.nytimes3xbfgragh.onion/

讓所有人想看到的人都有辦法看到是紐約時報的目標,所以就推出了許多不一樣的方式讓使用者可以看到內容...

The Times is dedicated to delivering quality, independent journalism, and our engineering team is committed to making sure that readers can access our journalism securely. This is why we are exploring ways to improve the experience of readers who use Tor to access our website.

Google Cloud Platform 的 DLP API

在「New ways to manage sensitive data with the Data Loss Prevention API」這邊提到三月的時候就推出了 DLP API (在「Discover and redact sensitive data with the Data Loss Prevention API」這邊提到的),不過沒什麼印象:

The Data Loss Prevention (DLP) API, which went beta in March, can help you quickly find and protect over 50 types of sensitive data such as credit card numbers, names and national ID numbers.

這次看了一下範例,可以直接對圖片上面分析:

先記起來,看起來之後應該有機會用到?(像是分析使用者上傳的圖片)

Cloudflare 的 CEO 將被傳喚說明濫用權力

Cloudflare 的 CEO Matthew Prince,將會被法院傳喚說明 Cloudflare 在沒有收到法院傳票的情況下就終止服務的原因,以及一直不肯在沒有法院傳票的情況下移除盜版網站的 policy:「Cloudflare CEO Has to Explain Lack of Pirate Site Terminations」。

預期會有兩件事情被拿出來訊問,第一件是推廣新納粹主義以及白人優越主義The Daily Stormer 被主動終止服務:

In August, Cloudflare CEO Matthew Prince decided to terminate the account of controversial neo-Nazi site Daily Stormer.

第二件是終止網頁挖礦的服務:

Just a few days ago Cloudflare suspended the account of a customer for using a cryptocurrency miner. Apparently, Cloudflare classifies these miners as malware, triggering a punishment without a court order.

應該會有很精彩的結論 (對 Cloudflare 不利),來等著看戲...

2011 年的研究,開放辦公室與病假的關聯性

忘記從哪邊冒出來的連結,反正是個 2011 年的研究:「Sickness absence associated with shared and open-plan offices--a national cross sectional questionnaire survey.」。2011 年在丹麥的研究:

METHODS: The analysis was based on a national survey of Danish inhabitants between 18-59 years of age (response rate 62%), and the study population consisted of the 2403 employees that reported working in offices. The different types of offices were characterized according to self-reported number of occupants in the space. The log-linear Poisson model was used to model the number of self-reported sickness absence days depending on the type of office; the analysis was adjusted for age, gender, socioeconomic status, body mass index, alcohol consumption, smoking habits, and physical activity during leisure time.

都是與 cellular office 比較,可以看出大於六個人的開放辦公室病假的量高出許多:

RESULTS: Sickness absence was significantly related to having a greater number of occupants in the office (P<0.001) when adjusting for confounders. Compared to cellular offices, occupants in 2-person offices had 50% more days of sickness absence [rate ratio (RR) 1.50, 95% confidence interval (95% CI) 1.13-1.98], occupants in 3-6-person offices had 36% more days of sickness absence (RR 1.36, 95% CI 1.08-1.73), and occupants in open-plan offices (>6 persons) had 62% more days of sickness absence (RR 1.62, 95% CI 1.30-2.02).

CONCLUSION: Occupants sharing an office and occupants in open-plan offices (>6 occupants) had significantly more days of sickness absence than occupants in cellular offices.

看起來只是拉數字出來分析... 另外信心區間的洞好大 XD
