    1. Josh Sargent, a member of the Akwesasne Mohawk community in upstate New York, where Hoover researched the impact of industrial contamination in the St. Lawrence River for her dissertation, said she’s “a good person and always welcome here.” Debates about her identity seem to be taking place in the “bubble of academia,” he said, while the real challenges facing Native people are being overlooked. He said she’s doing important work, and her book, “The River Is in Us,” accurately depicted the environmental harm suffered by his community. “I hope people read it.”

      An important question here: her identity may not have been completely authentic, but is this a reason not to heed and consider her work on its own merit?

      How do any of us really know our identities?

    1. MyRocks tuning for better false positive rate

      With MyRocks, you can control the size of the bloom filter bitmap with the column family parameter memtable_prefix_bloom_size_ratio. For good performance, the filter blocks are cached in the RocksDB block cache and normally stay there since they are accessed frequently.

      The filter_policy variable controls the number of bits per key in the column family settings. By default, 10 bits are used per key which yields less than 1% of false positives.

    2. Bloom Filter factors

      1. Size of the bitmap
      2. Number of keys in the list
      3. Number of bits set to “1” for each key value

      The number of false positives would be low, but 1GB is a lot of memory. In most cases a bitmap of a few hundred bytes is sufficient.

    1. despite Twitter’s self-styled reputation as a public town square — where everyone gathers to see the same messages — in practice, the pandemic showed how users segregate to follow mostly those with similar views, argues information scientist Oliver Johnson at the University of Bristol, UK. For instance, those who believed that COVID-19 was a fiction would tend to follow others who agreed, he says, whereas others who argued that the way to deal with the pandemic was to lock down for a ‘zero COVID’ approach were in their own bubble.

      Digital town square meats filter bubble effect

      During the COVID-19 pandemic, Twitter gave voice to researchers, but the platform’s algorithms allowed users to self sort into groups based on what they wanted to hear.

    1. You can do searches that exclude certain labels. That is, searches like this will do what you expect: (label:MyLabel1 AND NOT label:inbox AND NOT label:MyBadLabel1) That search will show you only messages that: Do have MyLabel1 And do not have label inbox And do not have label MyBadLabel1 The tricks are: to get yourself out of conversation mode! (As @Ruben says above.) to use UPPER CASE for the logic operators (AND NOT will work, and not won't) If you leave "conversation mode" on, you will get confusing results. For example, doing that search above (with conversation mode on), will likely return messages that do NOT match your search. It may be a bit weird. Here's the deal: Conversations are collections of messages that all have the same Subject. When "conversation mode" is on, searches return entire conversations as results. So what should gmail search do if a conversation contains both a message that matches, and a message that does not match your search? You are probably expecting it to return conversations only if all messages in that conversation match. But that is not correct. Instead, Gmail search will return conversations even if only a single message in that conversation matches. So that means that if you do the same search above with "conversation mode" on, the results are likely to include messages that do not match your search!

      I came here looking for a way to exclude certain emails from searches in Gmail. I was trying to make sure some emails that were archived don't show up, and this approach works (but the Boolean operators must be capitalized):

      (label:label_I_want AND NOT label:label_I_dont)

      If the unwanted label msgs are a part of a conversation thread containing the wanted msgs, then I'll need to turn this off first:

      Go to the main Settings page, look for the “Conversation View” section, select the option to turn it off, and save changes. If you change your mind, you can always go back. source

    1. TikTok starts studying its users from the moment they first open the app. It shows them a single, full-screen, infinitely looping video, then gauges how they react: a second of viewing or hesitation indicates interest; a swipe suggests a desire for something else. With every data point, TikTok’s algorithm narrows from a shapeless mass of content to a refined, irresistible feed. It is the ultimate video channel, and this is its one program.The “For You” algorithm, as TikTok calls it, gradually builds profiles of users’ tastes not from what they choose but how they behave. While Facebook and other social networks rely on their users to define themselves by typing in their interests or following famous people, TikTok watches and learns, tapping into trends and desires their users might not identify.

      TikTok uses user-interaction signals, not stated preferences or friend relationships, in its recommendation algorithm

      The article describes how users are "surprised and unsettled" by the algorithm's choices for next videos. The system rewards interaction by serving up videos that are more desirable to users—a kind of virtuous cycle of surprise and delight.

    1. Filter gives me the impression of inclusion... so if I filter by fruits, I expect to see apples, oranges, and bananas. Instead, this is more like filter out fruits... remove all the fruits, and you're left with the rest. Filter in/out are both viable. One means to include everything that matches a condition, and the other is to exclude everything that does not match a condition. And I don't think we can have just one.

    1. In her confusion, Peter wrote an e-mail seeking advice from Rachel Tashjian, a fashion critic who writes a popular newsletter called “Opulent Tips.” “I’ve been on the internet for the last 10 years and I don’t know if I like what I like or what an algorithm wants me to like,” Peter wrote. She’d come to see social networks’ algorithmic recommendations as a kind of psychic intrusion, surreptitiously reshaping what she’s shown online and, thus, her understanding of her own inclinations and tastes. “I want things I truly like not what is being lowkey marketed to me,” her letter continued.

      Recommendations based on your actions or on what the algorithm wants you to see

    1. While Brave Search does not have editorial biases, all search engines have some level of intrinsic bias due to data and algorithmic choices. Goggles allows users to counter any intrinsic biases in the algorithm.

    1. across() is very useful within summarise() and mutate(), but it’s hard to use it with filter() because it is not clear how the results would be combined into one logical vector. So to fill the gap, we’re introducing two new functions if_all() and if_any().

    1. Shirky has described the pre-Web era of publishing as working on a “filter, then publish” paradigm, subjecting text to editors and publishers before making it available; now, Shirky observes, the paradigm has flipped to “publish then filter.”103 In that sense, Shirky adds, “there is no such thing as information overload, there is only filter failure.”104

      Is das flipped classroom eigentlich auch schon ohnehin flipped - wie das publishing nicht erst gefiltert wird? Irgendwie (weiß noch nicht wie) glaube ich, dass diese Drehung auf der einen Seite auch im Klassenraum Wiederhall findet

    1. First, there is the life insurance rationale. Although the chance of a planet-wide calamity extinguishing our species is low, it is not zero.

      Notably Steven Hawking (and others) warned about this year ago already. Not to take away from Musk's achievements, but he's not the first to recognise and work on this problem.

Use git filter-branch with the "tree filter" to rewrite the commits so that anywhere foo/bar doesn't exist, it is created and all files are moved to it:

    1. There is an additional civic value here, one that goes beyond simply preserving professional journalism. For about ten years now, a few of us have been waging a sometimes lonely battle against the premise that the internet leads to political echo chambers, where like-minded partisans reinforce their beliefs by filtering out dissenting views, an argument associated with the legal scholar and now Obama administration official Cass Sunstein. This is Sunstein’s description of the phenomenon:If Republicans are talking only with Republicans, if Democrats are talking primarily with Democrats, if members of the religious right speak mostly to each other, and if radical feminists talk largely to radical feminists, there is a potential for the development of different forms of extremism, and for profound mutual misunderstandings with individuals outside the group

      This is an early reference to the idea of a "filter bubble" dating back to 2004 that predates the 2010 coining of the word by Eli Pariser.

    1. In previous eras, U.S. officials could at least study, say, Nazi propaganda during World War II, and fully grasp what the Nazis wanted people to believe. Today, “it’s not a filter bubble; it’s a filter shroud,” Geltzer said.

    1. One of the primary tasks of engineers is to minimize complexity. JSX changes such a fundamental part (syntax and semantics of the language) that the complexity bubbles up to everything it touches. Pretty much every pipeline tool I've had to work with has become far more complex than necessary because of JSX. It affects AST parsers, it affects linters, it affects code coverage, it affects build systems. That tons and tons of additional code that I now need to wade through and mentally parse and ignore whenever I need to debug or want to contribute to a library that adds JSX support.

    1. Without Shannon’s application of Dembski’s theorem, the internet and cable TV would not exist.

      This is a bit disingenuous as Shannon's body of thought preceded that of Dembski by several decades.

    1. Find Games in Your LanguageIf you're using Search in a language other than English, then your language will be shown first in the language filter control, and that control will be moved to near the top of the search page.
    2. Search is all about finding games that are relevant to you. If you don't own a VR headset, then seeing VR-only titles may not interest you. It's now possible to exclude these titles from your search, while still seeing VR-supported titles you can play without a headset.
    3. We've introduced new ways to leverage tags to find the games you'll love. Tags now show a preview of how many results will be returned, making it easier to see which are most relevant to your search. By popular demand, it's also possible to exclude tags from your search. If you're a fan of survival games, but not horror or zombies, you can now search to your exact taste.

    1. Beware online "filter bubbles"

      Relevance of right in front of you Internet means different things to different people Algorithms edit the web based on what you have looked at in the past "There is no standard Google anymore" Personalizing news and search results to each user "The Internet is showing us what it thinks we need to see, not necessarily what we need to see" "Filter Bubble"--information you live in online, you don't decide what gets in, but you definitely don't see what gets left out Mainly looking at what you click on first Information junk food instead of information balanced diet Gatekeepers found a new way to gate keep through algorithms What does this do to democracy? What sort of internet/web ethics need to be developed to get us through to the next thing? Algorithms need to be transparent and to give us some control; need a sort of civic responsibility Internet needs to be a tool of democracy and access for ALL

    1. Just as journalists should be able to write about anything they want, comedians should be able to do the same and tell jokes about anything they please

      where's the line though? every output generates a feedback loop with the hivemind, turning into input to ourselves with our cracking, overwhelmed, filters

      it's unrealistic to wish everyone to see jokes are jokes, to rely on journalists to generate unbiased facts, and politicians as self serving leeches, err that's my bias speaking

    1. 1. Explore the current situation. Paint a picture in words by including the “presenting problem,” the impact it is having, the consequences of not solving the problem, and the emotions the problem is creating for those involved.

      This step is somewhat similar to the EEC (Evidence/Example Effect Change/Challenge) model, often used with Feedback?

    1. Like all experts, academics are used to speaking to a specialized audience. That’s true no matter their discipline, from sociology to geotechnical engineering to classics. When you speak to a niche audience among peers, a lot of understanding comes for free. You can use technical language, make presumptions about prior knowledge, and assume common goals or contexts. When speaking to a general audience, you can’t take those circumstances as a given.

    1. “Design it so that Google is crucial to creating a response rather than finding one,”

      With "Google" becoming generic for "search" today, it is critical that students understand that Google, a commercial entity, will present different results in search to different people based on previous searches. Eli Pariser's work on the filter bubble is helpful for demonstrating this.
