Almost like these are videos coming straight out of the Dead Internet. https://en.wikipedia.org/wiki/Dead_Internet_theory
smlacy··on Pipe Inspection Robot [video]
What's with this kind of "Technical Innovation" video? Synthesized voiceover, royalty-free upbeat stock music background, myriad of grammatical and factual errors, over-hypes a fairly simple device, clearly developed/produced outside of the U.S. but is targeting an English-speaking audience.

I understand the "looking for funding" aspect of this, but if you can't get simple grammatical errors fixed, or honestly, if you can't afford to higher quality voiceover talent for your promotional video, then it just makes the product seem like a scam. Its fascinating that the producers of this device and video don't realize how bad this kind of thing could make them look.

There was lot of talk of "spherical gear" in the intro to the video, but as best as I could tell, the robot itself didn't use a spherical gear at all.

smlacy··on How to Ask Questions the Smart Way (2014)
What a pretentious bunch of gatekeeping nonsense.

Clearly, ESR (and anyone following the tenets of documents like this) are not actually interested in teaching anyone anything. They have a truly transactional perspective on "Question Asking" in that some questions are "worthy of answering" and others aren't. People who "Take without giving back" (his words) are exactly those who you're teaching. They absorb knowledge directly from those providing the answers.

Teaching is the act of understanding where your audience is in the learning process, and leading/guiding them through that journey in a kind and patient way. The truly ignorant don't know how to ask the question. Think of a child who's first learning computer programming. Think of an adult who's studying a foreign language for the first time. Think of the questions of a child who's never experienced snow.

> What we are, unapologetically, is hostile to people who seem to be unwilling to think or to do their own homework before asking questions. People like that are time sinks — they take without giving back, and they waste time we could have spent on another question more interesting and another person more worthy of an answer. We call people like this “losers” (and for historical reasons we sometimes spell it “lusers”).

And this is why "internet hostility" is a thing. Good job creating this horrible culture right from the start.

Please don't follow the advice of this column. Be patient. Encourage anyone and everyone to ask questions, even if they're "duplicates" or "easy to answer". Use the Socratic Method (ask questions that lead to more questions). Actually teach people things.

smlacy··on SimCity launched a decade ago, and it was so disastrous it killed the series
What a bizarre title. Obviously, SimCity has been around for a lot longer than a decade. The original Maxis SimCity launched in 1989.
smlacy··on Berkeley Mono Ligatures Release
Signed up for the "free trial" font (for personal use) and was particularly disappointed by this:

  Please note that the trial version has the following limitations:
  
  * Limited to ASCII-128 character set
  * Missing '7' and 'S' glyphs
  * Swapped: '/' and '\', '\*' and '#'
smlacy··on A Perceptually Meaningful Audio Visualizer (2016)
Interesting, and I'd love to see some more demos on "traditional" music (Symphonic/Orchestral, Jazz, Beatles, etc.). I'm sure the the highly synthetic and "pure" music used in the demo video sure leads to a fairly coherent visualization as compared to more natural/acoustic sources of sound.

Also, what about any stereo components? Capturing that in the visualization would also be nice.

Couldn't agree more! The real irony is that usually it's sold as "Docker makes installing, upgrading and maintaining easier."

Your belief isn't evidence, and you shouldn't present it as such.

Do you? Your arguments are classic whataboutism, and conspiracy/fearmongering.

Read up on the Burden of Proof. If you make outlandish claims, they have to come with substantial evidence.

smlacy··on Why 12 notes in Western music?
Its the use of the musical concept of Fifths that's the key here: We just derive the notes from what sounds good, not what makes sense mathematically? I'm just using Python to mirror the author's analysis -- you can derive "12 notes" pretty much just by using your ear and listening to the Fifths.
smlacy··on Why 12 notes in Western music?
Another possible explanation, which I'm surprised the author didn't go through is the "Circle of Fifths" which basically says:

Since Fifths sound so great, why not just keep doing that? When we get to the next octave, then come back down. If we get to a place that's "pretty darn close" to another note, then stop. The Python explanation looks like:

  f = 440
  for i in range(13):
      print(i,f)
      f = f * 3/2
      if f > 880: f=f/2.0

  0 440
  1 660.0
  2 495.0
  3 742.5
  4 556.875
  5 835.3125
  6 626.484375
  7 469.86328125
  8 704.794921875
  9 528.59619140625
  10 792.894287109375
  11 594.6707153320312
  12 446.00303649902344
Note that after exactly 12 steps, we're back at 446 which is "pretty close" to 440. So, we take this set of notes, sort them, and just jigger it a little bit to get the 12 notes we know today.
smlacy··on Ask HN: DALL-E was trained on watermarked stock images?
Prompt Engineering can help a lot but yes, you're basically right: People are generating many, many images and sharing only the best ones with the fewest artifacts.

For simple prompts with little additional guidance, all the diffusion image generators I've seen/used will produce output about like what the author linked most of the time. There are always a few gems, and honing in via prompt engineering helps immensely.

smlacy··on Using A Very Old Machine
In totally the same boat!

My daily driver home machine is an i5-760 (Released in 2010!) with a GTX 1060, and it works GREAT. I play lots of RTS-like games in 4K via Steam (Stellaris, Civ, Timberborn, Factorio, Valheim, etc) and there's absolutely no problem whatsoever. The "pcmasterrace" mentality that makes you think nothing works without the latest & greatest CPUs & Graphics is just blatantly false.

I've always run Ubuntu on it as my daily driver, and I think that's part of my success. Windows machines of this age are seem to be more susceptible to long-term performance degradation.

As a comparison, I routinely use it side-by-side with much more recent machines (Intel 10th gens) provided by my workplace, and all the machines feel nearly identical in speed and performance to my 12-year old beater.

My only regret/hope is that my ancient motherboard doesn't seem to support more than 8G RAM, which is a bit annoying given how cheap memory is at this point.

I'm not sure what "Wait at location because there was no better train" means?

Are you massuming a 3h40m trip for a specific time-based appointment? I think the use case of this kind of train is more similar to a flight with one or more nights at destination, so that the specific arrival time is not that important.

smlacy··on A WebGL Music Visualizer
Cute idea and great execution. The first track I tried [1] has no discernible "Beat" so it kinda just goes wild at its own tempo, a total mismatch for the music I was playing.

smlacy··on JetBrains Mono – the free and open-source typeface for developers
Once a (freely available) file is downloaded onto a computer that I own & control, they don't have any legal right to restrict what I do with those file(s), as long as I don't generate any derivative works. Using the font in a terminal or editor does not constitute a derivative work.

For example, I can use this as my terminal font on my Debian machine, and write code using it, but I can't post a screenshot of that terminal or code to Twitter.

smlacy··on JetBrains Mono – the free and open-source typeface for developers
SF Mono (https://developer.apple.com/fonts/) is also an amazing font, but generally left out of most online comparison tools due to licensing issues. But, it's freely available for personal use, and is certainly worth a look, and has been my preferred fixed width font for quite some time.

SF Mono works great in any system (not just Fruit) but you'll need to use a few tools to dig down to get the OTF's out of the DMG.
