Remove DEFINER clause from MySQL Dumps - Stack Overflow | https://stackoverflow.com/
Solution for error messages like
ERROR 1449 (HY000) at line 1434: The user specified as a definer ('superman'@'%') does not exist
I don't think there is a way to ignore adding DEFINERs to the dump. But there are ways to remove them after the dump file is created.

- Open the dump file in a text editor and replace all occurrences of DEFINER=root@localhost with an empty string ""

- Edit the dump (or pipe the output) using perl:
<code class="language-bash">perl -p -i.bak -e "s/DEFINER=\`\w.*\`@\`\d[0-3].*[0-3]\`//g" mydatabase.sql</code>

- Pipe the output through sed:
<code class="language-bash">mysqldump ... | sed -e 's/DEFINER[ ]*=[ ]*[^*]*\*/\*/' > triggers_backup.sql</code>

python - parsing XML file gets UnicodeEncodeError (ElementTree) / ValueError (lxml) - Stack Overflow | https://stackoverflow.com/
You are using the decoded unicode value. Use r.raw raw response data instead:
<code class="language-python">r = requests.get(url, params=payload, stream=True)
r.raw.decode_content = True
etree.parse(r.raw)</code>

which will read the data from the response directly; do note the stream=True option to .get().

Setting the r.raw.decode_content = True flag ensures that the raw socket will give you the decompressed content even if the response is gzip or deflate compressed.

You don't have to stream the response; for smaller XML documents it is fine to use the response.content attribute, which is the un-decoded response body:
<code class="language-python">r = requests.get(url, params=payload)
xml = etree.fromstring(r.content)</code>

XML parsers always expect bytes as input as the XML format itself dictates how the parser is to decode those bytes to Unicode text.

How does plastic get in the ocean? 5 questions we need to answer to fix plastic pollution - Vox | https://www.vox.com/
In other words, making environmentalism a social norm is one of the best ways to get people to be more aware of their behavior. Using the plastic straw ban as an example, he explained, “if everybody else in the restaurant is using them, and the context condones their use (e.g. straws on tables or put into drinks when served), then this increases the likelihood that an individual will act in accordance.”

MediaWiki FAQ - Meta | https://meta.wikimedia.org/
How do I purge cached pages?

1. You can use ?action=purge on individual pages to update their cache dates.
2. There is a global $wgCacheEpoch variable which can be set in LocalSettings.php to invalidate all prior cache entries (see DefaultSettings.php)
3. If you want to purge all pages in the parser cache, truncate objectcache table from the wiki database. You may use this command:

<code class="language-sql">TRUNCATE TABLE objectcache;</code>

Hint: If this fails, you might be using a prefix for your database tables!

Python import statement semantics - Stack Overflow
<code class="language-python">import lxml.html as LH
doc = LH.parse('http://somesite')
</code>
lxml.html is a module. When you import lxml, the html module is not imported into the lxml namespace. This is a developer's decision. Some packages automatically import some modules, some don't. In this case, you have to do it yourself with import lxml.html.

import lxml.html as LH imports the html module and binds it to the name LH in the current module's namespace. So you can access the parse function with LH.parse.

Chat is a greedy mode of communication.

* It doesn’t care if you are deep in flow.
* It begs you to incessantly clear its notification badges.
* It buries important conversations among idle chatter when you snooze it.

Opinion | The Best Book for 2018 Is 25 Years Old - The New York Times
It has become fashionable for writers to talk about the transformative power of empathy in fiction. But that potential is realized only when empathy is deployed in conjunction with an understanding of power and how it functions.

Jess continually marks the ways oppressive systems are most damaging — the way they force those who are oppressed to hate themselves and identify with their oppressor. And to navigate them, you are often asked to kill off any feeling or natural part of yourself to survive.
