i can't believe how nicely html-alchemist plays with clojurescript. among all the bad things in the world, i'm having a blast writing fully-featured apps in a fraction of a megabyte, in a lisp
i'm working on a ttrpg where player characters are represented as tarot decks. it's called The Emerald Green and it's about people who got caught in fae pacts
i'm writing it in clojure because lisp is awesome and clojure is a lisp and clojure is awesome

This Autumn, the ten local councils now controlled by ReformUK will need to work to set out the budgets that are legally required in Spring.... this move from 'made-up numbers' & statements without execution, to the real world of budget setting will do two things:
1. it will reveal where Reform has workable ideas & where its just fantasy politics; and
2. whose local interests they will be sacrificing to balance the books....

Die Ergebnisse zeigen, dass die Fleisch- und Milchproduktion für 60 Prozent der Treibhausgasemissionen der Landwirtschaft verantwortlich ist, während die Produkte selbst weltweit nur 18 Prozent der Kalorien und 37 Prozent des Proteingehalts liefern. Wenn jeder aufhören würde, tierische Lebensmittel zu essen, könnte die weltweite Ackerlandnutzung um 75 Prozent reduziert werden. Es gibt so viele Untersuchungen dazu, die alle zum gleichen Schluss kommen. Den Sinn einer pflanzenbasierten Ernährung anzuzweifeln, ist in so unsinnig, wie den Klimawandel anzuzweifeln. independent.co.uk/life-style/h…
Hello from Nepal, where Mastodon, along with other social media apps, have been banned, as per the Nepal Telecommunications Authority and the Supreme Court, effective today, unless they enlist the app and comply with all the legal, tax and vague demands regarding content "moderation" stuff.
This is the YouTube channel of Nepal Telecommunications Authority, Nepal. Nepal Telecommunications Authority is the regulator body of the telecommunication sector of Nepal.

what do they mean by “Mastodon”? Only mastodon.social? All mastodon.* instances? Only instances that run Mastodon but not e.g. Pleroma/Friendica? Everything on the Fediverse?
How do we tell these folks that they have no idea of what they’re talking about?
I don't know how they expect to ban Mastodon as a whole, or if these dinosaurs even know/understand/comprehend how Mastodon and the ActivityPub network works, but I'm certain they intend to DNS block the main .
proving the point that most of the political institutions are run by a bunch of tech illiterates who can’t even crop a screenshot but then talk about blocking websites, platforms or whole protocols.
I don't know how they expect to ban Mastodon as a whole, or if these dinosaurs even know/understand/comprehend how Mastodon and the ActivityPub network works, but I'm certain they intend to DNS block the main .social site, as they've done with TikTok, and a massive list of adult websites in the past.
They probably are just blocking all the largest social media sites people use. M.s being the largest instance gets targeted. But considering there's a million random forums or small Fediverse instances or chat servers or whatever else, without some deep packet inspection stuff, it'd be really hard to block everything. @ewen @ashmeshedup

VERY IMPORTANT UPDATE:
Protests and demonstrations began today, led by #GenZ, including students like me, against #Corruption, #Nepotism, and the ban of social media which they've used until now to share their voices.
Protests and demonstrations began today, led by #GenZ, including students like me, against #Corruption, #Nepotism, and the ban of social media which they've used until now to share their voices.
During this, it has been reported that water spray, gear gas and rubber bullets were deployed, injuring and killing protestors (identity uknown), who got shot and was being treated.
Reports of deaths have gone up to 17 according to some outlets, with alleged lethal bullets used.
Day 2 of the protests continues, with demands for justice for the the unarmed students killed yesterday.
While no casualties have been reported today, there have been reports of arrests being made.
Balen, The mayor of Kathmandu, the capital, has shown support for the movement, and has condemned Prime Minister K. P. Oli, outright calling him a terrorist who, not being a father himself, could never understand the pain of losing his children.
While local German politics claims that housing in Germany is expensive mainly because of bureaucracy and that the solution is simply to build, build, build, one should always keep in mind that this is a global systemic problem of assets and not just a small homegrown German issue.

Ok, time to step away... I'm looking at 100G switches optics and thinking... well, it's not TOO much more. I have no rational need for it. Or 40, or 25, or 10 really, but 1 is definitely gotten too slow, and 10 is the next. step up. Maybe I'll just do 25G on the risers. You know, just in case.
This board has already been fabbed (xgdr.net/2025/08/15/ceres-revA…) so I'm not going to be spending much time worrying about looking for pinout or basic "does it boot" issues.
I'm just gonna jump right in without much of an intro, you can read the blog and look at the files in the repo for a summary. The tl;dr is that this is a pre-existing FPGA design with an XCKU5P that has some SI issues and has a planned respin.
First observation: There's a general lack of dedicated return current paths on all of the high speed signals.
Seen here on the SYZYGY connector, almost all of the diff pairs transition to other layers in close proximity to the connector, but there's no return path vias.
The P0.D4 vias for example are going from L1 (ref L2) to L6 (ref L7), but are about 7.7 mm away from the closest ground via that connects the L2 and L7 vias.
I could simulate this, but I can tell just by looking at it that it's not good.
While we're looking at this connector, the connector pads are also 280 μm wide while the differential pair tracks are 150 μm. So we're going to have a significant low-Z bump on the connector.
Possible fixes are
1) Make the pads smaller (will cause solderability issues)
2) Move the reference plane further away and enlarge the trace so the pad is matched (will require a new stackup and also significantly reduce density of routing)
3) Add a ground plane cutout under the connector to reduce coupling to the reference plane and bring the impedance back up to target. This is normally the best choice.
The top layer has ground fill on it, which is something I discourage for a bunch of reasons.
First, pragmatically, it leads to complex shapes that don't mesh well in field solvers and make simulation slower.
Second, you get lots of undesired coupling to top layer signals that will throw off impedance matching. P0.TX2 for example is a de facto grounded coplanar waveguide, while P0.REFCLK is a microstrip for most of its length.
You need to either explicitly design your routing as CPWG (ensuring the top layer return path is continuous, unbroken, and well stitched to the inner layer) or pull the top ground back far enough it won't significantly couple - at which point you're often better off just removing it outright.
Third, there's a lot of isolated copper features that will resonate unless well stitched to inner layers (often not possible in the available space, or will hurt routing density if possible).
For example, the "finger" between P0.D4- and P0.TX3+ is going to strongly couple to both signals, but has no connections elsewhere except to the plane at the east side.
The uncoupled length is about 5.7 mm. Guesstimating an 0.7 velocity factor, I'd expect it to behave as a quarter-wave stub for frequencies with a free space wavelength of (5.7 mm * 4) * 0.7 or 15.96 mm. So we'd expect to see a resonance at 18.78 GHz causing a significant dip in insertion loss.
We'd also probably see a half-wave resonance at half that frequency (9.39 GHz).
And finally, because of how chopped up it gets by signal routes and component pads, top layer ground just doesn't act like a very good return path because it's so discontinuous. There's really not much use for it in most designs.
The DDR is even worse from a return current perspective. Most of the ground pins on the SODIMM are connected to the top layer ground fill only, and the nearest ground vias are at the far north edge of the connector.
The nearest ground via to the B1.D1 layer transition (from L1 to L6) for example is over 8mm away.
On the plus side, the connector pad size and the low-impedance DDR single-ended tracks are well aligned, so there shouldn't be a significant impedance mismatch at the SODIMM itself.
Moving on to the PCIe, we see more of the same issues: giant 0603 coupling caps (0402 or even 0201 would be better from a parasitics perspective) with no ground cutouts for impedance matching, plus L1-L8 vias with no return path provided.
This is particularly bad because there's no stitching vias or ground vias in general near the PCIe fingers.
So the nearest return path for say the TX4_C pair going between the L2 and L7 ground planes is probably the via coming off FPGA ball E1 a whopping 17 mm away.
This is a pretty consistent pattern across the whole board, I'm not going to call out every instance of it (QSFPs etc).
In short, there's a general lack of attention paid to return currents every time a SERDES or DDR signal changes layers, and lack of ground plane voiding on BGA and coupling capacitor pads causing low-Z mismatches.
Ideally, every time a high speed signal changes layers, there should be a return current via - or two for a diff pair - in close proximity. If you want to go all the way, you can do full EM solver simulation of the transition including the coupling between via barrels/pads/planes and vias to optimize the exact clearance from via to plane, spacing from via to via, etc. But just having a dedicated return path is way better than not having one.
See example from one of my boards (not the one being reviewed)
Some more good examples of best practices in this space. This is 5 Gbps QSGMII on a 6-layer board but the same concepts apply to higher layer counts.
In this particular example some of the layer transitions are right under one side of the capacitor using filled via-in-pad, but the same key concepts apply:
1) Any time you have to put a large component pad, in this case an 0402, in an impedance matched signal, add a ground plane cutout to bring the impedance back up to target
2) Provide stitching vias between the two reference planes any time a signal changes between layers referenced to different planes.
I'm not sure many folks realize just how persistent the warming from CO2 is.
Here is a set of 1000-year climate model runs (using FaIR) simulating one year of CO2 emissions (40 gigatons in 2020); a millennia later the world has not cooled back down!

Das Bild zeigt eine Zeichnung mit zwei Figuren vor einem Hintergrund mit den großen blauen Buchstaben "SU". Auf der linken Seite steht ein Mann in einem dunklen Anzug mit weißem Haar und einer besorgten Miene. Er spricht: "Jessas! Warum 'etz aa des?" (Jesus! Warum jetzt das?). Auf der rechten Seite geht eine Figur, die Jesus darstellt, mit einem Kreuz auf dem Kopf und einem weißen Gewand, in Richtung der Buchstaben "SU". Er trägt einen blauen Ring und spricht: "Urheberrechtsverletzung." Die Zeichnung spielt auf die Thematik Urheberrechtsverletzungen an, indem sie Jesus als Symbol für die Gerechtigkeit oder die Strafe für solche Verletzungen darstellt.

Picked our MG4 up from the repair place today. Good as new! Now just hoping all the insurance stuff goes through smoothly. The dude who backed into us with his ute while we were parked doesn't seem to have filed a claim through his provider yet, probably because there was virtually zero damage to the back of his tray. But I'm hoping our provider just takes care of everything. Fingers crossed! Good to have our car back anyway!
Das Bild zeigt eine satirische Illustration, in der ein Mann in einem Anzug und mit einem überdimensionalen Kopf die Erde in einen gelben Chipper steckt. Der Chipper, mit der Aufschrift "CHIPPER" versehen, spuckt Geldscheine aus. Der Mann hat ein breites Grinsen und wirkt zufrieden. Die Erde ist in der Chipper-Maschine zerdrückt, und Geldscheine fliegen aus dem Auspuff. Der Hintergrund ist in einem hellen Grün gehalten, mit einem gelben Kreis, der den Chipper und den Mann hervorhebt. Die Illustration kritisiert die Ausbeutung der Erde und die Priorisierung von Geld über Umwelt und Nachhaltigkeit.
