I have a new article! It took a long time but I think it was worth it, hopefully you'll enjoy it too. https://t.co/TboGxob68u

Many thanks to @vassilis3D, @moguzhan_k and @aortizelguero for the help and encouragement

(Me): so, we create this "virtual memory" to trick processes into thinking they have a contiguous address layout

(Medieval peasant): Would not thy abstraction swell the tally of mem'ry lookups?

(Me): well, yes. to deal with that we created the "translation lookaside buffer"

To anyone reading this who might be facing a similar crossroads, meet my son Josh.

Josh is 3 and has Down Syndrome, the very condition shared about here in this post. We received a prenatal diagnosis at roughly 10 weeks. Some of the complications we feared happened, but that wasn't the end of the story. Josh was born early and spent a month in the hospital. At 1 year old, he had open-heart surgery. Now he's 3, loves life, and is thriving. The hard days didn't win.

If anyone else finds themselves in a similar place, reach out. There's a whole community of people here to support you. It hasn't always been easy, but he's worth every bit of it and then some.

@valigo The most fun I've had coding recently was writing crstl, a replacement std library. I learned a lot about the small string optimization, fixed containers, the API design, adding extension functions, etc. It's at a point where I rarely need anything new and if I do, I just add it

Here’s how Polish fans celebrate their club’s victory.

Before leaving the square, they cleaned up after themselves. No one was beaten up or raped.

Be Like Poland.

Interested in learning more about the creation of “Zootopia 2”? Join this talk in the Rendering and Volumes session at SIGGRAPH 2026.

'Path Guiding in Disney’s “Zootopia 2”' explores the first large-scale production use of Disney’s second-generation path guiding system in Hyperion Renderer and the technical advances behind it. The team shares practical methods for improving rendering efficiency, evaluating performance without costly comparison renders, and integrating path guiding into production workflows.

Great graphics on GBC. The water reflection and animations are impressive

This is a real place in Vienna.
Bellotto painted it in 1758.
I recreated it in voxels. 😊

『METAL SLUG』の開発中、魔法使いと呼ばれていた天才プログラマー、ANDY君が作ったドット絵エディター『キャメル』。
それは、まさにドッターたちにとって、夢のようなツールでした。

その名前は、当時ANDY君が好きだったタバコ『Camel』から取ったもの。
ツールのアイコンには、タバコのパッケージに描かれているヒトコブラクダ『オールドジョー』を、ANDY君自らドット絵で描き起こしたものを使っていました。

アイレムで使っていたドット絵エディター『さだやんペイント』には、『海底大戦争』でSUSUMU君が表現していた水中背景の揺らめきのような、ラスタースクロール表現を簡単に作れる機能があったんです。

その機能は『キャメル』にも引き継がれており、『METAL SLUG』でも、砂漠の遠景を陽炎のように揺らす表現などに使っていました。

その機能を使い、さらに一歩踏み込んだ表現として作られたのが、UFOが放つトラクタービーム等のエフェクトです。

トラクタービームの絵は、ビームの形と重なる背景の絵をそのまま使い、その絵のカラーパレットを、発光して見える数種類のカラーに入れ替えながら、さらにラスタースクロールをかけることで、ビームを通して見た背景が揺らいで見えるように表現しているんです。

このエフェクトを作ったのは、ドッターのTOMO君なんですが、UFOと背景の座標を完璧に一致させないと、なんちゃって半透明に見えなくなってしまうので、TOMO君は敵配置担当のmeeher君に、こう念を押しました。

「ビームエフェクトを1から作り直しになってしまうから、UFOと背景の座標は絶対に変更するなよ！」

すると、meeher君は、

「わかった、絶対に変えない」

と言っていたんですが、数日後UFOの位置を変えてしまいます。
meeher君は、TOMO君が、とんでもない手間を掛けてあのエフェクトを作っていたことを理解していなかったようで、めちゃくちゃ怒られていました。

あの頃のTOMO君はスケジュール度外視で、納得がいくまで時間を使ってしまうドッターだったので、通常の担当作業に組み込むのは難しかったんです。

そこで、後輩たちの絵の手直しや、クオリティアップに繋がる作業を、やりたいようにやらせていました。

手が遅くても良い仕事をするクリエイターには充分な時間を与え、作品全体のクオリティアップに努めてもらう。
そういう贅沢な人員配置も、メタスラの拘りの一つかもしれません。

あの半透明に見えるエフェクトは、そうやって時間を気にせず動ける存在と、『キャメル』があったからこそ生まれた表現なんでしょうね。

@davidspringate And you should be! When the mobile department at Fusion closed and you and Richard and Kevin were relocated with us, and I remember your stories about the tech and how it was developed. This memory resonated a lot harder later when ntt was canned for UE4
