Like computers are so hard.
The very beginning of Flash Man's stage in Mega Man 2, prior to encountering any enemies. One hit point remains.

Well, “if you want something done right…”
A "Hex Workshop" window. The semi-garbled output on the right side of the window, alongside a table of hexadecimal values, contains strings like "ATOMIC FIRE" "TIME STOPPER" and "MESSAGE FROM DR. LIGHT."

Around the thirty- or fourtieth time I heard a podcast ad for a “digitial photo frame” over the holidays, I decided to rig up a cheapo display to a Raspberry Pi that mounts a directory on my NAS and cycles through any images it finds in there. “Shitpost robot” is a working title.
A small black screen propped against the corner of a white wall, behind which is a faint green glow. The screen displays the “just walk out” meme by Da Share Z0ne.

Had “PROPERTY OF CAMBRIDGE PUBLIC SCHOOLS” stamped on the side, uh, for some reason.

Also, I’ll send a couple of JavaScript for Everyone stickers to the first person that replies to this with the deep-cut reference I snuck in there.

(8.5x5.5 copy of Da Share Zine included for scale.)
A stack of shrink-wrapped stickers with the "JavaScript for Everyone" logo and a red, seemingly hand-written "is" incorporated between "JavaScript" and "for." They're sitting on top of the back cover of a zine with a grainy black and white grim reaper displayed on a classic "beige toaster" Macintosh computer.

No other JavaScript course gives you the feeling... of JavaScript for Everyone.

Said time is, of course, the week of Black Friday — about which I have some Big Feelings: wil.to/newsletters/...

So, if you’re in a position where you’re able to do so, help me make sure JavaScript for Everyone lives up to its name by paying a little more for it.

Hear me out:

You gotta make your own fun.
Close-cropped screenshot of a video timeline. The audio track reads "Rush Coil - 8-Bit Christmas - O Christmas Tree .mp3." Above it, a track containing a JavaScript for Everyone title card that spans several seconds. Above that, a video track containing a tiny thumbnail of someone wearing an incredibly shitty Santa costume.

...uh oh.
Two browser windows side-by-side, both containing editable fields reading "this is a test." The word "is" is highlighted in the left window, which is marked on the right. The word "test" has a highlight in both, and the cursor is on "test" in the right, revealing a floating tooltip that reads "do comments work" attributed to Wilto and an "add comment" field.

Alright, where was I?
Truncated screenshot of a page layout in a design tool. The top reads "Welcome to Multipage Version," pointed at by a clipart illustration of a 1950s-style man. Below it reads "a zine about HTML elements" in Comic Sans. Below that, in a monospace font, text: "From the editor. Alright. here we go. The images issue. Deep breaths." Sub-heading: "What's your problem?" Text: "This is the images issue." Sub-heading: "So?" Text, partially cut off, appears to read "that's like my entire deal."

I've started using Lynx for a couple of things — for real — and I regret to inform you all that It Rules, Actually:
A screenshot of the heading, description, signup input, and first five posts under https://wil.to/posts/#js4e, rendered on the command line. "Dictated but not Written" has cursor focus.

@arturo182.bsky.social Hey, is there any shot at a Serpente comeback one day? They'd be the perfect little board for slapping together custom Framework expansion cards.
A QT Py with a male-male USB C coupler alongside a Framework expansion card. The bare board/adapter is slightly longer.

The short answer is “yes,” please find the long answer attached here.
The "sickos" meme. A menacing cartoon with stubble, frizzled hair and eyebrows, and pointed teeth stands with hands pressed to a closed window, reading a shirt that says "sickos." The dialog bubble reads "yes... Ha ha ha... YES!"

I've never really done video for anything before, so I tried out a couple of different intros for this while I was trying to figure out how to do all this in the first place. But, I dunno.

C’mon, bud, get outta there; it's almost Halloween.
A 12 foot skeleton halfway emerged from between the cushions of a small outdoor couch, posed as if struggling.

This one is a little more understated, if you’re not the sort who secretly always wants to dress like they're in Hackers (1995), which — unfathomable to me, personally, frankly.

A beige t-shirt with the "JavaScript for Everyone" logo in the "pocket" position. The word "is" appears to be hand-written in red, after "JavaScript."

While you wait, chriskirknielsen.com and I cooked up a couple little somethings to show off your love* of the `#${!+[]+![]}` programming language in the world:

A beige t-shirt with a design modeled after a blank VHS cassette cover. A black/red strip at the top reads "ES 262." The center contains a red-to-purple striped globe with "JS" in a blocky, rounded, retro-future font. Below it, a small bannerreads "`#${!+[]+![]} since 1996` — a template literal that evaluates to "#1 since 1996" — wrapped in stylized parentheses. Below that, the JavaScript for Everyone logo, with a red "is" added after "JavaScript."
