roman concrete being "rediscovered" for the 17th time is beginning to become a pet peeve for me, especially now that I've actually learned about the real history of roman concrete and how at literally no point in history between then and now has the recipe ever actually been lost. like we've known the recipe for it all along. we didn't always understand the mechanism behind its strength, but we already figured the fundamentals of it out decades ago, not like last year
[edit: I should also have mentioned the "self-healing" thing; roman concrete can withstand minor cracking and recover some of its strength over time, in the presence of water. it basically redissolves slightly and then fuses together due to having, essentially, what function as unactivated cement inclusions. it's not just that it's strong enough to last 2000 years, it has other significant properties that give it longevity. still, I first heard about the quicklime thing years ago, and afaik it wasn't actually a properly new discovery even then. and you can't combine the self-healing with rebar, so it has to be unreinforced]
roman concrete is just expensive and requires specific materials only found on the italian peninsula, and basically nobody is building roman-style permanent monumental structures (and most failures in concrete buildings are actually caused by rust, the concrete could last much longer if used by itself and in compression-only strain) so people use portland cement instead.
portland cement is extremely cheap and works well enough and usually already lasts longer than the rest of the building, and its properties are easily controlled with additives. also, roman concrete takes way longer to cure and become fully load-bearing than portland cement, and unreinforced concrete structures are massive and heavy. plus we can drain an area for underwater construction nowadays, the romans didn't have that option and needed concrete that could cure underwater
of course portland cement is also one of the biggest CO2 emitters so we can't just carry on like this forever, so it's a bit like plastic in that respect: it's a wonder material that we're highly dependent on that if we keep on using will destroy our ecosystem. but tbh I just don't think roman concrete is the solution, at least for 95%+ of our current concrete use

Dear craftingverse,
does anybody have an *EU* source for #wearableElectronic materials such as conductive thread? up to now I've bought it from the Italian branch of an US distributor, which took care of not having to pay VAT to the postman, but still counts as buying from the US for, let's call them other reasons.

Hey, Bradley, we already started a review of old licenses a year ago. It's been taking some time since there are a LOT of old licenses. I take it this is something you'd want to be involved in?
Catch: we're using proprietary software to track the review.

I'd like to take a step back & design the right structure. I'd prefer a non-partisan “Appeals Court” model for this, triggered by written appeal requests, rather than blanket review done in same manner as the original license approvals.
IOW, I hope OSI'll establish a check-and-balance procedure on the entire existing license review process.
But I'm open minded on the methods & means: Glad to discuss more if I'm elected!

I'm flabbergasted at how many important volunteer opportunities at #OSI mandate proprietary software use.
It's hard to avoid proprietary software in nonprofit management but FOSS nonprofits should make accommodations for staff & volunteers who refuse on ethical grounds. FOSS orgs mandating proprietary software is akin to an animal rights org requiring staff to eat meat for lunch.

Let it be on record.
I drove my mother to do things, but there was no parking available, so I dropped her where she had to be and was faced with a choice of what to do before picking her up again:
* drive back home (feasible, but probably would have meant having to come back as soon as I arrived)
* stop at a nearby small hardware shop and do some shopping for things I didn't need
* visit a cemetery
and exercised self-restraint and choose the latter.

* fermarmi al brico vicino e comprare cose che non mi servono
* visitare un cimitero
e con sforzo di autocontrollo ho scelto l'ultima.

Hexagonal Pattern Weights
Posted on February 24, 2025
Tags: madeof:atoms, craft:3dprint, craft:sewing
For quite a few years, I’ve been using pattern weights instead of pins when cutting fabric, starting with random objects and then mostly using some big washers from the local hardware store.
However, at about 22 g per washer, I needed quite a few of them, and dealing with them tended to get unwieldy; I don’t remember how it happened, but one day I decided to make myself some bigger weights with a few washers each.
I suspect I had seen somebody online with some nice hexagonal pattern weights, and hexagonal of course reminded me of the Stickers Standard, so of course I settled on an hexagon 5 cm tall and I decided I could 3D-print it in a way that could be filled with washers for weight.
Rather than bothering with adding a lid (and fitting it), I decided to close the bottom by gluing a piece of felt, with the added advantage that it would protect whatever the weight was being used on. And of course the top could be decorated with a nerdish sticker, because, well, I am a nerd.
I made a few of these pattern weights, used them for a while, was happy with them, and then a few days ago I received some new hexagonal stickers I had had printed, and realized that while I had taken a picture with all of the steps in assembling them, I had never published any kind of instructions on how to make them — and I had not even pushed the source file on the craft tools git repository.
And yesterday I fixed that: the instructions are now on my craft pattern website, with generated STL files, the git repository has been updated with the current sources, and now I’ve even written this blog post :)

Water Resistant Hood
Posted on February 23, 2025
Tags: madeof:atoms, craft:sewing, FreeSoftWear
Many years ago I made myself a vest with lots of pockets1 in a few layers of cheap cotton, and wore the hell out of it, for the added warmth, but most importantly for the convenience provided by the pockets.
Then a few years ago the cheap cotton had started to get worn, and I decided I needed to replace it. I found a second choice (and thus cheaper :) ) version of a water-repellent cottonand made another vest, lined with regular cotton, for a total of just two layers.
This time I skipped a few pockets that I had found I didn’t use that much, and I didn’t add a hood, which didn’t play that well when worn over a hoodie, but I added some detached sleeves, for additional wind protection.
This left about 60 cm and some odd pieces of leftover fabric in my stash, for which I had no plan.
And then February2 came, and I needed a quick simple mindless handsewing projects for the first weekend, I saw the vest (which I’m wearing as much as the old one), the sleeves (which have been used much less, but I’d like to change this) and thought about making a matching hood for it, using my square hood pattern.
Since the etaproof is a bit stiff and not that nice to the touch I decide to line3 it with the same cotton as the vest and sleeves, and in the style of the pattern I did so by finishing each panel with its own lining (with regular cotton thread) and then whipstitching the panels together with the corespun cotton/poly thread recommended by the seller of the fabric. I’m not sure this is the best way to construct something that is supposed to resist the rain, but if I notice issues I can always add some sealing tape afterwards.
I do have a waterproof cape to wear in case of real rain, so this is only supposed to work for light rain anyway, and it may prove not to be an issue.
As something designed to be worn in light rain, this is also something likely to be worn in low light conditions, where 100% black may not be the wisest look. On the vest I had added reflective piping to the armscyes, but I was out of the same piping.
I did however have a spool of reflector thread made of glass fibre by Rico Design, which I think was originally sold to be worked into knitting or crochet projects (it is now discontinued) and I had never used.
I decided to try and sew a decorative blanket stitch border, a decision I had reasons to regret, since the thread broke and tangled like crazy, but in the end it was done, I like how it looks, and it seems pretty functional. I hope it won’t break with time and use, and if it does I’ll either fix it or try to redo with something else.
Of course, the day I finished sewing the reflective border it stopped raining, so I haven’t worn it yet, but I hope I’ll be able to, and if it is an horrible failure I’ll make sure to update this post.
- and I’ve just realized that I haven’t migrated that pattern to my pattern website, and I should do that. just don’t hold your breath for it to happen O:-). And for the time being it will not have step-by-step pictures, as I currently don’t need another vest.↩︎
- and February of course means a weekend in front of a screen that is showing a live-streamed conference.↩︎
- and of course I updated the pattern with instructions on how to add a lining.↩︎

There's an email thing called dovecot. (Details irrelevant, if you've never heard of it all you need to know is it's an email thing.)
TIL there's a physical thing called a dovecot, which is a cot (bed) for doves and pigeons.
Upon learning this, I was like "oh! like carrier pigeons! that is a clever pun!" but no it turns out they mostly just kept pigeons to eat their eggs and use their poop as fertilizer :( (I probably have vastly inflated ideas of how often pigeons were used to carry messages)
Also I realized just now while typing this that the word "cottage" comes from "cot". Language is fun!

Thanks to “digging through a box of old microcontroller boards until I found an #arduino leonardo compatible one and digging through another box until I found an IR receiver and a random cheap remote labeled car mp3” I now have a remote I can use to control mpv to watch videos when I'm further away from the laptop/pc keyboard than the length of my arm (or when there is an ironing board between myself and the laptop).
18 out of 21 buttons have been assigned to a function
3 out of 21 buttons actually have the function that is labeled on the remote
3 additional buttons have a function that may be vaguely hinted at by the label on the remote (very vaguely)

Is it a good use of my time to do so, when I can buy twill tape from the haberdasher? (not in linen, and not in the colours I can buy linen thread in)
Does Nm 24 yarn / thread mean that it will take forever?
Note that I've started with a few rows of plain weave, just to stabilize everything, and I've only woven the bare minimum I felt confortable with before removing the warm from the clamps and moving it to the backstrap loom.
Also, this brown yarn is cotton, not linen, I'm keeping the nice linen for when I'm sure that this whole thing can actually work.

I've just watched Bernadette Banners' video “How to Identify Quality in Clothing (A Rant)” and I'm a bit surprised by the way serging is basically condemned as evil.
I do hate the serger (and the serger hates me), so on the clothing I make I tend to use french seams, bound edges and all those finishes, but other than the odd flat felled seam on sportswear I don't think I've ever seen a professionally made garment where the raw edges weren't finished with serging, even when it was an actual seamstress doing custom work.
Of course there is serging and serging, and the video does mention what to look for for better (or less worse, as they framed it) serging, but I just don't understand how one is supposed to find garments that aren't serged at all for sale.

Some nuanced privacy advice:
- Signal is good, and you should use it because it strikes an effective balance in the optimization problem that is getting people to use secure technology.
- You should think really, really hard before using any technology whose entire threat model depends on centrally operated infrastructure remaining trusted and uncompromised. Especially ones based in jurisdictions without effective democratic institutions.

Ultimately, the main questions you really need to ask yourself are:

Privacy itself is a technology, a powerful one, and you should learn to wield it effectively to accomplish the goals you have.

Conference Talk Timeout Ring, Part One
Posted on February 4, 2025
Tags: madeof:atoms, madeof:bits
A few ago I may have accidentally bought a ring of 12 RGB LEDs; I soldered temporary leads on it, connected it to a CircuitPython supported board and played around for a while.
They we had a couple of friends come over to remote FOSDEM together, and I had talked with one of them about WS2812 / NeoPixels, so I brought them to the living room, in case there was a chance to show them in sort-of-use.
Then I was dealing with playing the various streams as we moved from one room to the next, which lead to me being called “video team”, which lead to me wearing a video team shirt (from an old DebConf, not FOSDEM, but still video team), which lead to somebody asking me whether I also had the sheet with the countdown to the end of the talk, and the answer was sort-of-yes (I should have the ones we used to use for our Linux Day), but not handy.
But I had a thing with twelve things in a clock-like circle.
A bit of fiddling on the CircuitPython REPL resulted, if I remember correctly, in something like:
import board
import neopixel
import time
num_pixels = 12
pixels = neopixel.NeoPixel(board.GP0, num_pixels)
pixels.brightness = 0.1
def end(min):
pixels.fill((0, 0, 0))
for i in range(12):
pixels[i] = (127 + 10 * i, 8 * (12 - i), 0)

time.sleep(min * 5) # min * 60 / 12Now, I wasn’t very consistent in running
end, especially since I wasn’t sure whether I wanted to run it at the beginning of the talk with the full duration or just in the last 5 - 10 minutes depending of the length of the slot, but I’ve had at least one person agree that the general idea has potential, so I’m taking these notes to be able to work on it in the future.One thing that needs to be fixed is the fact that with the ring just attached with temporary wires and left on the table it isn’t clear which LED is number 0, so it will need a bit of a case or something, but that’s something that can be dealt with before the next fosdem.
And I should probably add some input interface, so that it is self-contained and not tethered to a computer and run from the REPL.
(And then I may also have a vague idea for putting that ring into some wearable thing: good thing that I actually bought two :D )

e per cena spezzatino cucinato in modo da rispettare una serie di restrizioni alimentari con — oltre ad altre verdure — insalata belga stracotta e sciroppo di Liegi.
come contorno patate lesse, perché non posso mangiare patatine fritte.
e una bottiglia di Rochefort 10 (divisa con @Diego Roversi , perché siamo troppo vecchi per bere una bottiglia di birra a testa, figuriamoci una bottiglia di birra *belga*)

and dinner was spezzatino cooked to accomodate a number of food restrictions, with — among other vegetables — overcooked belgian endive and syrop de Liège.
the side was boiled potatoes, because I can't have frites.
and a bottle of Rochefort 10 (shared with @Diego Roversi , because we are too old to drink a bottle of beer each, nevermind a *Belgian* one :D )

This afternoon's project: "A self-hosted Wikipedia (and other bits) clone, using kiwix on a Raspberry Pi 4"
I thought that it might be a good idea to have a local (well, on my local network) copy of Wikipedia, and some other bits.The go-to tool for this seems to be kiwix, and that’s what I used, running on a Raspberry Pi.
The hardest part was faffing around with the SSD...

It's not that. The volumes involved are staggering. Fibreglass rebars suck, also: not very stiff, and brittle.
You can have stainless steel rebars, and they're not used partly because it's 4x the cost, but also because they're super painful to form. They are used in marine applications.
In reality, with a thick enough concrete cover (as per the norms) rebars never rust (out of the sea).
