New blog post: How to silence noisy alerts during OpenShift cluster upgrades using Prometheus and Alertmanager.
Covers detecting upgrades via cluster_version metric, extending the detection window with max_over_time subqueries, and using inhibit rules to suppress expected alerts during the recovery period.

This has been in the works for years, but I might finally be happy with how this is turning out. Everything just snaps together perfectly, joins up seamlessly, and I'm finally confident I can reproduce these results indefinitely.
There's still some minor tweaks to make, some extra brackets and supports and thing, but I'm confident in saying the basic system is 100% complete.
#Thrixels v2 is a go.

Me: I don't need to print more than 500 of these at once.
Also me: Let's give a thousand of them a go at once.
Result: 1,024 #Thrixels printed at once, 100% yield, zero failures. Trust the process!
Here's a bit of my workflow. The long green thing is a breaker bar that slots over the top of a row of Thrixels and makes it easy to pop them off the raft without them going everywhere. And the swoopy scoop helps me collect them and pour them into labeled bags.

Five hours and 18 minutes is an awful long time to lay down 31 grams of PLA, but that includes the time to print the PLA/PETG support raft, and still works out to ~36 seconds per individual part.
I could fit somewhere around 2,000 total #Thrixels on a single plate on my X1, but I don't see a need to - 500ish over 5 hours of printing gives me plenty of time to do other things between plate clears, and more than that increases the risk of failures, which would cost more time. #3DPrinting

#Thrixels update. Currently tweaking the shape of the very top of the tiles, to maximise the amount of surface area taken up (so the tiles look like they fill the space) without overlapping and causing the base to bow. 39.76mm means there's 0.12mm of 'slack' on each side when compressed with calipers, which seems to be getting filled adequately, and there's no warping visible from the side. Couple more tests to reduce the gaps in tile corners and I think this design is done. #3DPrinting

Ah, that's better. It's gotten enough layers in that it's up to switching to a different colour for the top layers, and it's making an interesting pattern. This is two hours into a four hour print, and by the end of it I should have 25 new #Thrixels bases to play with.
-
Not only does this look like there is no seam at all, when you insist to your brain that there definitely is one, its best guess is a row or two away from where it actually is.
The sense of satisfaction I'm getting from this is on par with building a complicated gaming PC from scratch, and doing all the cable-tying before pressing the power button and finding it boots and works perfectly the first go. I am ridiculously happy with how this project is unfolding. #3Dprinting #Thrixels

I regret to announce I have invented voxel teeth.
In better news: That's 512 v2.0 #Thrixels successfully printed at once - not the most individual parts I've ever printed together, but not far off it, either.
These are at a 0.16mm layer height, while the originals needed to be at 0.12 to work reliably, so that + the simplified geometry makes for a much faster print. Four hours for ~30g of parts sounds slow, but that's still under 30 seconds per individual part!

So, clearance is a fun thing to get right in #3DPrinting. If you have a 10mm cube, and a 10mm hole for it to go into, it won't fit - 3D printing is just too variable a process for things to work like that. You'd need to build some clearance in - probably 0.25mm on each side, so you'd end up with a 9.5mm cube; my #Thrixels have a 0.1mm gap between the tiles and the part of the baseplate they grip to.
But stuff gets weird when you go small - like single digit multiples of your nozzle width small.

#CGAPrints update: Push Plastic's Dark Teal PLA has entered the chat. Massive thanks to @filamentcolors for helping me get some of this to Australia without spending a fortune on shipping (despite the very best efforts of UPS)!
This stuff is almost exactly the right colour and shade for CGA teal, but is surprisingly matte for a plain PLA colour, doesn't love Bambu's default ironing settings, and jams at the back of my AMS, so this stuff will be exclusively reserved for making #thrixels.
-
@timixretroplays neato! Tell me more about these Thrixels. I can't find much info about them anywhere!

Lastly, slicing some 3D models for printing. A plate of my #Thrixels went from taking 2 minutes 20 seconds down to *57 seconds*, Frank Deschner's Designer Moon Lamp dropped from 16 minutes to 8 and a half, and the worst case I found was slicing a very large Hilbert curve model I made, which dropped from 1:15 to 44 seconds. A 40-60% improvement!
3D slicing is an interesting mix of single- and multi-threaded tasks, and this CPU upgrade basically halved the time it takes to do each one. 5/🧵

@mutthew @timixretroplays @3dprinting You can print something like this: https://www.printables.com/model/441038-countsort-tray with one of the sides removed and you can easily transfer the #Thrixels into the bags.

This was always my vision for #Thrixels - modular bases that clip together in a way that allows the tiles on top to just seamlessly... tile... to form a pattern. The tiles are very easy to locate and snap in, there's enough room in there for bigger patterns to not collide and warp apart, not a single individual tile popped off in repeated drop tests, and while a ton of dimensional tweaking obviously remains, all the core functionality is suddenly there.
This has been a good day.

@3dprinting Nine hundred individual functional #Thrixels parts printed on a single plate, with 100% yield. I don't know if there's a world record for this, but it's certainly a personal best - and I'd like to try 2,000 at a time when I'm in full production mode. #3DPrinting

Ok, interesting #CGAPrints / #Thrixels update today. The last few colours - brown, grey and dark green - have come out with noticeably crap quality, probably my printer needs some preventative maintenance after churning out thousands of the same part, but also I should probably build in more tolerance because different filaments are going to act differently.
I'll keep building this stockpile for early pixel art tests, but might revise for time investments in bigger projects. #3DPrinting

Progress on #CGAPrints is slow due to life and other stuff. A full print of 1k #Thrixels is ten hours, basically a whole printer day, and I don't like running it overnight, so if I don't get a plate started in the morning it's not a day this project gets furthered.
I'm up to five packs done out of 16, so in theory I could have the rest knocked out in a week. Realistically it'll take longer, but momentum is slowly building up!

A better photo of my 16 #CGAPrints filament collection, and my progress so far on turning them into #Thrixels for pixel art.

#CGAPrints Release Candidate 2. Magenta is now Atomic Filament's Perfect Purple, and a slightly lighter shade than in RC1. Cyan is also a little brighter in real life (it's devilishly difficult to take this photo meaningfully, so trust me on this).
I think it's time to line up some filament and print a thousand-odd #Thrixels of each colour, then do some test sprites to see how these colours actually work together!

So what's the big idea? Here's the big idea - these boomerang pieces get glued to a final surface, ideally a pre-cut wooden sheet, and aligned using a set of base pieces, whether completed with #Thrixels or not. I need to find a bit of scrap wood and do a test assembly.
I also need to go back to the drawing board on the base pieces and the slots those tabs fit into, because for some reason they're back to not fitting correctly. Two steps forward, one step back. #3DPrinting

Finally catching a bit of free time for hobby stuff, so I'm testing some ideas I had for #Thrixels V2.
I'm still very proud of my original work, but it had very complicated geometry, was slow and difficult to print, and its limitations meant that any time I wanted to start a big project with them, it just went straight into the too-hard basket.
Here I'm shrinking and stabilising parts while increasing footprint area for reliability, and testing a fix for large projects warping. #3Dprinting

I'm proud to announce the first public release of #Thrixels, my system for #3DPrinting pixel art! After several months of work, I think it's finally ready to inflict on other people - please give it a go if you're interested, and let me know how you get on with it.

Boosts, suggestions, and any other feedback would be highly appreciated!

Having a nice relaxing evening with a kit of #Thrixels I've built up - featuring the coolest non-gaming-related pixel art I know of: https://en.wikipedia.org/wiki/Arecibo_message

I wasn't actually expecting this print to succeed. This is a plate of 256 #Thrixels printed in PLA on a raft of PETG. PLA and PETG seem to act well as breakaway support for each other, and as PETG is less than half the price of Bambu's Support W by weight, I think I'll stick with it!
This is also important because it's a cheap and reliable way to get good adhesion - important when a Thrixel has just barely four square millimetres of base surface area.

My printer's been busy almost exclusively churning out #Thrixels for the last few weeks (I really wish I could justify a second printer, now that I'm into multiple projects that more resemble mass manufacturing than rapid prototyping), but I have to say these little widgets have proven to be excellent fidget toys in the meantime.
-
In the spirit of sharing failures as well as successes, I wasted an entire printer-day by rushing to set up a whole plate of #Thrixels in the morning and copied and pasted the wrong model - I nearly ended up with a thousand individual *holes* instead of mosaic tiles, which would've been totally useless.
Not a big waste of filament - if I'd let it finish, it would've been 70g or so - but losing a day of time on the project (I wasn't around to clean/reset) is irritating.
-
13 hours to print less than 60 grams of PLA? Sure, why not! Today's the day I embark on the final proof-of-concept test for making large #Thrixels mosaics, and this print is two of the four base pieces that will be combined to make up the whole. Now taking guesses as to what classic bit of pixel art I will be recreating here!
-
Substantial, visible progress has been made today. This particular image requires 2,561 green #Thrixels, of which I've printed about a third, but every other colour is now in place.
Unlike with the QR code, where I went line by line, I'm doing the outline and all other details first before simply filling the rest of the space with green.
The result of this strategy is that, as of today, it looks like someone chroma-keyed a #dopefish. Should be finished next weekend!

@3dprinting a tripartite working solution: the eggcrate-like substrate, a Lego-like grid for the substrate to snap to and join with, and the #Thrixels themselves. I think with smaller (8x8) joining pads that click in more positively, this system could be expanded in size almost indefinitely. I think only internal joining edges need the #frek subtracted away, otherwise the thrixels can lean out over the edges. Also, I think there's room to expand the top tile surfaces slightly! #3DPrinting

Ask your doctor today if Bowl O' Plastic is right for you! The next step in my #Thrixels madness is seamlessly joining multiple panels together to support larger mosaics. Here's a test with no extra clearance - not only is there a gap, it's exacerbated by the tiles pushing the thin substrate walls outwards, so those will have to be cut away in the next attempt.
That metal pin is from the #GravisGamePad project - I will need to find a different "dowel" material.
