If you had the option to add new features to your primary language, what would they be? Is there something from a foreign language you'd like to import to your primary language?

A couple examples:

• A prefix to indicate intensity or degree. BBS/early hacker jargon had terms like "k-rad" to mean 1000x (2^10?) as radical as "rad" without the prefix.
  That Montessori preschool was t-cool but why would they think calling it "Hobbledehoy" was a good idea?
• Making an indication of how confident you are in an a statement obligate and easy. I hedge all the time because I think it's important to convey, but it's clunky. We do a bit of that non-verbally but that doesn't translate to text, and has the other complications of non-verbal cues.
  It would be nice if there was an established vocabulary to quickly convey things like "experienced first-hand, repeatedly", "99% certain", "I've heard but never looked into", etc. From there it would be nice if this was as required as the gender, in gendered languages.

So, for this thread, I'm specifically not asking for detailed explanations about the spiritual or philosophical aspect that goes behind your motivations to meditate. A brief explanation is almost certainly required, though.

Mostly, I wish to know practical things, details that often go unsaid, like:

• What kind of meditation do you practice?
  • How can I Google it?
• Where and when do you meditate, and why?
• Do you do it alone?
• How do you prepare for meditation?
• What you do afterwards?
• How frequently do you meditate, and for how long?
• If you sit at all, in what position do you sit?
  • Where do you sit? The ground, a mat, a cushion, a chair, your bed?
• Do you keep your eyes closed or open?
• Do you concentrate on your breathing?
• Do you breath through your mouth or nose?
• Do you count your breaths or visualize them in any way?
• Is there any particular breathing technique involved?
• Do you use any aid such as noise generators, soundscapes, timers, meditation apps, etc?
• Do you push thoughts away?
• Do you concentrate on any object, physical or otherwise?
  • statues, amulets, images, mental images, mantras, etc.
• What do you do if...
  • your legs go numb?
  • there's a fly on your nose?
  • there's mucus on your mouth or throat?
  • you must cough or sneeze?
  • you're itchy all over?

I never considered myself an introvert or shy. I’ve always been comfortable talking with strangers, whether that was in my college class or just sparking up a conversation with someone next to me in line.

I haven’t talked to a stranger irl since the pandemic started and I’m running scenarios in my brain about how I would talk to someone when I just met them. And every situation I’m going through I’m being awkward and uncomfortable.

I can talk to my family and my cousins, who are essentially my only friends, just fine but that’s different since there’s already an established way of communication there.

I just feel like I’m gonna be so rusty at talking to people, which is a shame because I’ve spent years learning how to talk to strangers in a certain way to make them comfortable and to very easily have a conversation. And I feel like I lost all of that now.

I wouldn't say Tildes is wholly uninterested in philosophy, that is certainly not the case. You're a smart bunch full of intellectual curiosity!

I have been making an effort to share more philosophy articles on ~humanities for some time now. They always get a few votes, but discussion is not as common. This is in no way a complaint about our users, philosophy is often highly specific and long-form, and it is hard to predict if a long article will eventually pay off for you.

Generally, philosophy posts that are related to technology, computer science, consciousness/AI, and, to a lesser degree, social change, attract more attention. But there are not as many of those (and I'm personally interested in other stuff too...).

As I said, the purpose of this post is not to complain. I believe the lack of participation in certain topics reflects the size of our community, our most common interests, and our repertoire.

With that in my mind, I would like to know how could I better engage our community in discussions about philosophy. Apart from the themes I mentioned, what are you interested in or curious about?

I could make an effort to include a short introduction or conversation starter on every post, but I'm not sure what is the sentiment regarding that (would that be considered/labeled as noise?). Besides, I'm not a philosopher or anything of the sort, just a layman with a lot of philosophy websites on my feed. So my guess is as good as everyone else's.

It would be awesome if we had a ~humanities.philosophy someday, but I wonder if that is realistic at all...

This thread is posted weekly, and is intended as a place for more-casual discussion of the coronavirus and questions/updates that may not warrant their own dedicated topics. Tell us about what the situation is like where you live!

Sometimes a comment thread is very very toxic/controversial and I would like to avoid getting sucked into it. Just because my decision-making is much better at 2pm than it is at 2am. I understand I can and should exercise self-control, and I'm working on it, I assure you! In the meantime, if at all possible, it would be nice to remove certain comments from my view, along with its children. Thanks!

This below is a summary of some real-world performance investigation I recently went through. The tools I used are installed on all linux systems, but I know some people don't know them and would straight up jump to heavyweight log analysis services and what not, or writing their own solution.

Let's say you have request log sampling in a bunch of log files that contain lines like these:

127.0.0.1 [2021-05-27 23:28:34.460] "GET /static/images/flags/2/54@3x.webp HTTP/2" 200 1806 TLSv1.3 HIT-CLUSTER SessionID:(null) Cache:max-age=31536000
127.0.0.1 [2021-05-27 23:51:22.019] "GET /pl/player/123456/changelog/ HTTP/1.1" 200 16524 TLSv1.2 MISS-CLUSTER SessionID:(null) Cache:

You might recognize Fastly logs there (IP anonymized). Now, there's a lot you might care about in this log file, but in my case, I wanted to get a breakdown of hits vs misses by URL.

So, first step, let's concatenate all the log files with cat *.log > all.txt, so we can work off a single file.

Then, let's split the file in two: hits and misses. There are a few different values for them, the majority are covered by either HIT-CLUSTER or MISS-CLUSTER. We can do this by just grepping for them like so:

grep HIT-CLUSTER all.txt > hits.txt; grep MISS-CLUSTER all.txt > misses.txt

However, we only care about url and whether it's a hit or a miss. So let's clean up those hits and misses with cut. The way cut works, it takes a delimiter (-d) and cuts the input based on that; you then give it a range of "fields" (-f) that you want.

In our case, if we cut based on spaces, we end up with for example: 127.0.0.1 [2021-05-27 23:28:34.460] "GET /static/images/flags/2/54@3x.webp HTTP/2" 200 1806 TLSv1.3 HIT-CLUSTER SessionID:(null) Cache:max-age=31536000.

We care about the 5th value only. So let's do: cut -d" " -f5 to get that. We will also sort the result, because future operations will require us to work on a sorted list of values.

cut -d" " -f5 hits.txt | sort > hits-sorted.txt; cut -d" " -f5 misses.txt | sort > misses-sorted.txt

Now we can start doing some neat stuff. wc (wordcount) is an awesome utility, it lets you count characters, words or lines very easily. wc -l counts lines in an input, since we're operating with one value per line we can easily count our hits and misses already:

$ wc -l hits-sorted.txt misses-sorted.txt
  132523 hits-sorted.txt
  220779 misses-sorted.txt
  353302 total

220779 / 132523 is a 1:1.66 ratio of hits to misses. That's not great…

Alright, now I'm also interested in how many unique URLs are hit versus missed. uniq tool deduplicates immediate sequences, so the input has to be sorted in order to deduplicate our entire file. We already did that. We can now count our urls with uniq < hits-sorted.txt | wc -l; uniq < misses-sorted.txt | wc -l. We get 49778 and 201178, respectively. It's to be expected that most of our cache misses would be in "rarer" urls; this gives us a 1:4 ratio of cached to uncached URL.

Let's say we want to dig down further into which URLs are most often hitting the cache, specifically. We can add -c to uniq in order to get a duplicate count in front of our URLs. To get the top ones at the top, we can then use sort, in reverse sort mode (-r), and it also needs to be numeric sort, not alphabetic (-n). head lets us get the top 10.

$ uniq -c < hits-sorted.txt | sort -nr | head
    815 /static/app/webfonts/fa-solid-900.woff2?d720146f1999
    793 /static/app/images/1.png
    786 /static/app/fonts/nunito-v9-latin-ext_latin-regular.woff2?d720146f1999
    760 /static/CACHE/js/output.cee5c4089626.js
    758 /static/images/crest/3/light/notfound.png
    757 /static/CACHE/css/output.4f2b59394c83.css
    756 /static/app/webfonts/fa-regular-400.woff2?d720146f1999
    754 /static/app/css/images/loading.gif?d720146f1999
    750 /static/app/css/images/prev.png?d720146f1999
    745 /static/app/css/images/next.png?d720146f1999

And same for misses:

$ uniq -c < misses-sorted.txt | sort -nr | head
     56 /
     14 /player/237678/
     13 /players/
     12 /teams/
     11 /players/top/
<snip>

So far this tells us static files are most often hit, and for misses it also tells us… something, but we can't quite track it down yet (and we won't, not in this post). We're not adjusting for how often the page is hit as a whole, this is still just high-level analysis.

One last thing I want to show you! Let's take everything we learned and analyze those URLs by prefix instead. We can cut our URLs again by slash with cut -d"/". If we want the first prefix, we can do -f1-2, or -f1-3 for the first two prefixes. Let's look!

cut -d'/' -f1-2 < hits-sorted.txt | uniq -c | sort -nr | head
 100189 /static
   5948 /es
   3069 /player
   2480 /fr
   2476 /es-mx
   2295 /pt-br
   2094 /tr
   1939 /it
   1692 /ru
   1626 /de

cut -d'/' -f1-2 < misses-sorted.txt | uniq -c | sort -nr | head
  66132 /static
  18578 /es
  17448 /player
  17064 /tr
  11379 /fr
   9624 /pt-br
   8730 /es-mx
   7993 /ru
   7689 /zh-hant
   7441 /it

This gives us hit-miss ratios by prefix. Neat, huh?

This thread is posted weekly - please try to post all relevant US political content in here, such as news, updates, opinion articles, etc. Extremely significant events may warrant a separate topic, but almost all should be posted in here.

This is an inherently political thread; please try to avoid antagonistic arguments and bickering matches. Comment threads that devolve into unproductive arguments may be removed so that the overall topic is able to continue.

For the past month, I have been reading "The Wisdom of Psychopaths" by Kevin Dutton which delves into traits, behaviors, and motivations behind psychopaths. This book isn't just about serial killers but rather also the "successful" functional psychopaths such as stockbrokers, politicians, and business executives. You can read an excerpt from the book here if interested. A few interesting takeaways that I have had from the book so far are the innate cues that some people have on picking up on psychopathic cues. This is like speaking to someone and getting the heebie-jeebies from them for some reason. Apparently, women are more perceptive to this than men.

So, I'm curious if you have ever met a person that gave off that vibe, and what in particular gave you that vibe?

Sometimes Tildes users give people healthcare advice. Sometimes that advice disagrees with the advice already given by a qualified registered healthcare professional. That might be okay if the tildes advice was compliant with national guidance, but sometimes it isn't. Sometimes it's bad, dangerous, advice.

Should Tildes have rules about this?
