gitlab I hate you and the next time anyone asks about what they should use, I am going to make sure they neverneverEVERuse gitlab.

I don't get the redhat kill cycle thing.You have an arms industry, and they're being uncharacteristically honest about what they do.There's no chaff about euphemising what they do (eg calling dead civilians "collateral damage", soldiers "operators", or war "kinetic activity").The defence (arms) industry makes things that kill people and break their stuff so your politicians can have shorter wars with fewer casualties.This is how the sausage is made. If you don't like it, reassess why:

If you're upset that wars exist, start electing politicians that don't start wars of aggression.If you're upset that you were exposed to shocking words, think about why you have been insulated from gory truth for so long.If you think the arms industry simply shouldn't exist, consider Ukraine.

Otherwise, what I see looks like people who enjoy BBQs, but are hypocritically up in arms when they are exposed to the mechanics of industrial food slaughter.You have input to this system. Become a vegetarian/reform your politics.You can't be angry at this but go back to eating war-raised meat.

I am pleased to announce the first collaborative deployment between telekline communications and Øl Telecom.telekline has provided installation and configuration consultancy to install 24 fixed telephone lines at Øl Telecom's research site at rLab.Pleased to have worked with @hugh from Øl to realise this technology's full potential.

telekline looks forward to further collaboration and is preparing a Memorandum of Understanding for interconnection, to be negotiated and agreed at EMF 2026, a mutual point of presence.

If anyone in the UK (especially the South East/London) has unusual telephones they would donate or sell for a modest fee, I would be interested on behalf of the Reading hackerspace, rLab. As long as they work or are easily repairable for a standard POTS network/landline. See below a Dutch ex-prison service phone, as well as a ruggedised phone used airside at Heathrow. Boosts welcomed.

A successful night in the hackspace - new old Mac Mini laser engraved and another successful 10" rack conversion.Process follows.

For the rack mount, a quick spin through OpenSCAD after taking measurements of where the mounting screw holes are on the side of the switch.I have generic 10" 1U and 2U patterns made from https://boxes.hackerspace-bamberg.de/ that really help.After that, fire the model through PrusaSlicer and it's 1h from "print" to part, and some M3 screws to attach.

The Mac Mini was a bit more involved, but also more interesting.1. Download LIDAR heighmap data from DEFRA (I used this data when I was doing my masters - great resource).2. Whack it all into QGIS and normalise the tiles.3. Decimate the data (went from 1m to 200m per pixel resolution) to smooth, and then run contour analysis. Clean by deleting any lines by filtering length < some hundreds of meters. Export as SVG.

4. Take a zoomed out picture of the Mac from far away, to give you a minimally distorted reference image.5. Put it all in inkscape, using the known size of the Mac to scale to reference. Trace a red "keep out" layer we can use in lightburn to avoid tracing the laser over the plastic when we're doing the aluminium etch. (The apple logo gets a debian swirl in the end.)6. Chuck it all in lightburn.Cost:* Mac (recycled): £0.00* Open Govt Data: £0.00* QGIS: £0.00* Laser: £2.20 (11 min run)

Some things to note:* I was going to do this on our new fibre laser but didn't - it's both too small (it was originally going to be 4 carefully referenced cuts, rotating a new corner in each time, which is what the green quadrants were for) and too slow progress. Turns out the CO2 laser did a better job getting through the anodised layer *and* fits the whole cut in 1 pass.* The laser isn't 100% parallel and disperses after the focal point. This deposited some energy on the plastic/labels.

Related: the Mac Mini has a small IR sensor for use as a media centre with a remote control.I illuminated that with some oblique portion of the 30W of IR laser cutter beam.There's a real chance that sensor is toast, but I'd never use it anyway. Whoops.Finally, I would also have spent some time cleaning up the Debian swirl if I realised how many "bits" it had coming off the main swirl. It's deliberate, but on the laser it just looks a bit unclean/bitty, like a mistake.

With the exception of the lightburn (the laser control software), everything involved here was freely licensed.OpenSCAD, Inkscape, and QGIS are all GPL.Data:* DEFRA LIDAR is UK Open Government License.* Rackmount data isn't clearly licensed, but is generated by boxes.py - GPL.* Additional geo data from OSM is ODbL (but didn't go into the final cut, was just a tool to reference data against).PrusaSlicer/XL Firmware: (A)GPL.If anyone has leads on a lightburn replacement, I'm all ears.

If you like this kind of stuff, be sure to have a look for your local hackspace/makerspace.I'm a member at rlab, Reading, UK - https://wiki.rlab.org.uk/ .You can have a look for yours on the map at https://wiki.hackerspaces.org/List_of_Hacker_Spaces .Can't see it? Don't fret, local knowledge trumps an out of date wiki. Ask around, web search, etc.And of course, you can always start your own...

Have you ever had the need to roll 196 dice? My friend did and make a device to do so.If you want to try, I made a simulator here: https://pulham.info/dice.html(It's nowhere near as satisfying).

If you're curious, to get any combination in particular it works out to 1/(6^196) = 1 in 329340450472243364812480626171893311993046871415501103005770894240056272800632514675209984059226155321614826748978495239934000957189502501839518203641856

While really designed as a bit of art, it did bring up some really interesting discussions in the lab.For example, if you and your backgammon partner had full knowledge of the upcoming dicerolls, would you play differently?Is there a tabletop RPG mechanic where you can be "clairvoyant" and see the next row of dice rolls, meaning you can try to manipulate upcoming turn-taking to get high value rolls (or conversely, get opponent players/NPCs to unwittingly catch critical fails)?

These guys say they will do *any* request. The place is empty. Let's see them do Venetian Snares.
