Fixing Google App Engine SSL Certificate Renewal Failure

Hello! If you've landed here, your custom domain on Google App Engine (GAE) is throwing a NET::ERR_CERT_DATE_INVALID error and Google's managed certificate stubbornly refuses to renew itself. Here's what's likely happening and how to fix it. Cloudflare's Proxy In my case, my domain and subdomains are proxied through Cloudflare — including the ones pointing to GAE-hosted sites. If your domain's A and AAAA records are proxied through Cloudflare (the orange cloud), Google cannot see its own IPs when attempting to validate your domain for certificate provisioning. It hits Cloudflare's IPs instead, panics, and gives up with a Certificate activation has failed. DNS records could not be found warning in your Custom Domains tab. So in this scenario, we need to head to Cloudflare dashboard ➡️ back to GAE dashboard ➡️ wait ➡️ finally, Cloudflare dashboard. Head to Cloudflare Dashboard Head to your Cloudflare DNS dashboard and toggle all A a...

Just Schwarzenegger, Just Sylvester

There are actors who play characters. Then there are actors who are characters — and the character simply has no say in the matter. The Monoliths I was observing Arnold (Alois Schwarzenegger) and (Sylvester Gardenzio) Stallone in films. Those two specifically, because they have "zero range". Every time they played in a film, the supposed character kneeled down before them. We always saw them in films as... themselves. Right? Arnold Hercules in New York (1970) Confusingly mythological Arnold. As you can see, "Hercules" is the Roman version, but his daddy in the film was Zeus, the Greek god. Akin to "by Jove". It's all bonkers and we shan't question it. But still, the muscular Arnold. Conan the Barbarian (1982) Arnold with sword. Terminator (1984) T-800, you say? That's Arnold. Predator (1987) ...

Blogger Template Error Message: The reference to entity "display" must end with the ';' delimiter.

Error Message The error message on Blogger looks as such: My Case In my case, that was from a link (stylesheet) href value provided by Google Fonts. By default, they put the display=swap parameter in the URL — specifically, in the query string. On a regular HTML page, that should be fine. But on Blogger, it is unacceptable. Blogger employs super regular HTML . Ah, let's use this font. Splendid. Please save the template, Blogger. (Hits save button.) 🤖 Oi. Yes? 🤖 The reference to entity "display" must end with the ';' delimiter. What does that mean? 🤖 The reference to entity "display" must end with the ';' delimiter. (Removes the value after "display". Places ';' after "display". Hits save button.) 🤖 Oi. Yes? 🤖 The reference to entity "display" must end with the ';' delimiter. ⬆️ The XML parser saw the & symbol and it threw a robotic ...

It Was Nothing

Hi, there. 👋 Let's examine this phrase: it was nothing. One magnificent, centuries-old paradox that everyone uses and nobody questions. You've said it. I've said it. Your nan said it after knitting an impossibly intricate jumper for Christmas. We all say it, reflexively, automatically — like a social sneeze. Someone compliments us and out it comes , dressed smartly in the clothes of humility. But hold on just a moment. 🍺 Let's Dive Picture this: A bloke on an ordinary street pulls a dame clean out of the path of a speeding car. Adrenaline. Chaos. The sheer improbability of being exactly there at exactly that moment moving at exactly the right speed. The dame, breathless and alive, turns to him — Thank you so very much! I'd be dead if you weren't there! And he says: Oh, it was nothing. Nothing. He just casually dismissed a miracle as nothing. Which means, by his own accounting, one rung above nothing would be — what, exa...

Bullet Chess: Caro-Kann Defense: Exchange Variation

I played defence (black) here in a 1 minute bullet game on Lichess. My opponent resigned. Quite an intense game, that was. 🤔 Not much to tell, really. But if I brought this jittery-style to a classical game... 🤣 You can use your left and right arrows on your keyboard or use the mouse scroll to see the moves back and forth on the chessboard. But first, click the board.

Sneak Peak

Let's use large fonts: sneak peak. After 5 seconds or one hour and seven minutes, we should realise that there is something odd about it. Sneak = to go somewhere secretly, or to take someone or something somewhere secretly. Peak = the highest, strongest, or best point, value, or level of skill. 🤔 No, sounds correct. The Rhyming ea We tend to use "peak" rather than "pee" (obviously) — I mean "peek" (the intended one), because of the ea in both words. Let us examine: sn ea k p ea k . ⬆️ They look... matching! Indeed, but! There is peek = to look, especially for a short time or while trying to avoid being seen. No, that's not the word. Sneak peek ? 🤔 Voyeur? No. ... On second thought, where? Origin The term was conceived straight from the marketing pits of Frankenlandia, circa 1950s. Examples: Get a sneak peek at our brand new Ford V8! Sneak a peek at Betty's new casserole...

Sparring with Stockfish Level 6: Sicilian Defence: Dragon Variation

Hi. 😃 I played offence here in a 3 minutes blitz game against Stockfish chess engine — on Lichess. For our information, the Level 6 isn't a tutorial bot — it's a calibrated menace. I did 3-4 games before this particular game. Level 6 tends to play human‑like at times, and this was that one of those times. It did 2 "under pressure" moves, at 24th and 31st banters. I took the 31st. When its horse swung to c5 . I had.... a battering ram in position. And the horse... (Horse. ♞) Let me just... vacate the e6 square. Yes, that should frighten the enemy's queen. Neigh me, neigh! You can use your left and right arrows on your keyboard or use the mouse scroll to see the moves back and forth on the chessboard. But first, click the board. Horse = knight. But because the piece doesn't resemble a knight to begin with, it's a horse. A well-behaved horse, I presume. Here. ⬇️ ♞ (Horse. ♞) Oh hello, good sir. Might I interest you in some fine hay? ...
