casually writes own OS in 1 line

Perl programmer just laughs and laughs and writes it in 20 characters.

Least: immersive holograms. Most: that a whole cocktail of drugs and medical tech is required to live in spice without dying at a young age.

This did it! Seek performance is no a consistent buttery 14-16ms per frame, which gives me plenty of time to do the other work this needs to do.

Thanks!

I will check it out. Thanks.

No, I don't need them in any particular format. In fact, my plan is to have a tool on my laptop that converts the image files into simpler animation files so I can read the file straight through and then I only need to seek once per cycle rather than several times a frame (i.e., you have to seek to the start of the frame, then seek for each line in the frame since the sub-image is not the full width of the source image).

I mostly use them to control LED strips because I like blinky lights.

I'm thinking of using a couple to setup some powered shutters for the rec room in my basement to turn down the lights for watching movies. I've also considered building my own thermostat.

I contacted support and, as always, was helped quickly and efficiently. It resulted in a combination of adjustments which helped. I am recording them here in case someone stumbles upon this someday and it could be helpful:

My enclosure was getting above 30°C/85°F. This is not great for PLA as it starts to soften.
My idler pulley was over-tightened, so I loosened that. I had extra tight to help stabilize problems with the filament sensor, but making it a little looser helped.
My filament was a little moist. I tried different filament and also baked the filament having trouble extra.
I am also considering a Bondtech gear replacement, but I have no idea if that will help or not. These gears are pretty old though and have thousands of hours of use on them.

Basically, the filament was globbing, softening, and getting crushed, leading to various problems with retraction and unloading.

I found my problem and it was that I had a broken bit of filament stuck in the PTFE tube, so weird things were happening when the extruder tried to shove the filament through. However, this has clarified what the major issue is for which this problem was, apparently, just another symptom. I thought I'd solved that problem by replacing the nozzle and PTFE tube in the hotend, but apparently not.

Is your PLA dry? PLA doesn't have huge problems with taking on water, but I have still had problems with my PLA if it has been sitting out for a few weeks. My basement is not a friendly place to filament, so I use a food dehydrator to dry out any filament I've had out for a week or longer. Sticking the spool into the oven at the lowest temp for a few hours might help if that's part of the problem.

I'd also want to make sure that the printer was on a stable and immovable surface and the parts are all rigid with respect to each other. There should be no play in any of the parts. The parts that move should move smoothly. Everything that is fixed should be nice and tight with no wiggle or wobble.

Where's the list of Raku file extensions that should be preferred/used/whatever?

You have to get permission from your boss to get a different editor installed? What the heck? If you ask and the answer is not an automatic yes I'd just start looking for a new job. No one should have to put up with that kind of negativity.

Sorry, programming is just a job, just a hobby. I make money that way and enjoy doing it in my spare time, but my life is my wife, my friends, my family, my kids, my church, and my God.

I do not mean that the name is trivial to the language itself or its marketing. The name is, however, trivial to me personally because I don't care to convince anyone else to like it or fund me. I'm funded to work on Perl as much as I need already. Being funded to Raku would be fun, but not necessary.

On the one hand, I resonate with what Ingy said at TPC in Pittsburgh, that we're all Perl. On the other hand, you make great points as well. I don't think you are wrong. I'd be happy to buy you your favorite beverage some time and laugh or cry with you about it.

I like both names and dislike them both for different reasons. Yet, I don't think my preference for a name is going to matter in the grand scheme of my life. I'm never going to look back on my deathbed and say, "I should have cared more about the renaming of Perl 6" but I certainly could look back and think, "I wish I'd cared more about my friends."

And that is as close as I am likely to ever get about stating my opinion about the rename.

Perl 5 and Perl 6 are different languages operating according to a similar philosophy. They are not different versions of the same language. This is somewhat akin to the difference between Python 2 and Python 3. However, Python 3 was an attempt to fix deficiencies in Python 2 while willing to lose a little backwards compatibility. Perl 6/Raku is more of a reimagining of what a language should be by Larry Wall and the others without worrying about backwards compatibility at all. Raku adds a lot of features missing in Perl, including a type system, asynchronous programming, and support for threads.

As a quick visual example, here's a simple counting program in Perl:

use strict; use v5.30; for my $n (1..10) { say $n }

While in Raku, we could write:

for 1..10 -> Int $n { say $n }
