Beirut blast 3 years on: Footage shows moment of deadly explosion in slow motion
August 4, 2023, marks three years on from a deadly explosion that rocked the port of Beirut. Footage captured in 2020 by resident Agoston Nemeth on his iPhone SE shows the moment the huge explosion went off, sending a visible blast wave hurtling towards the camera. The blast killed over 200 and injured more than 6,000 people. The HD 4K video recorded Nemeth, a 42-year-old therapist from Budapest,
Deep Learning is such a fast-moving field and the huge number of research papers and ideas can be overwhelming. The goal of this post is to review ideas that have stood the test of time.

If you were to start in Deep Learning today, understanding and implementing each of these techniques would probably
Next.js のドキュメントには次のように記載されてる React will automatically cache fetch requests with the same input in a temporary cache. This is an optimization to avoid the same data being fetched more than once during a rendering pass - and is especially useful when multiple components need to fetch the same data.

CSSって難しい！ セレクタ「.a .b .c」と「.a :is (.b . c)」は同じに見えるけど実は違う、ブラウザはセレクタを右から左に読む
CSSの:is()疑似クラスが各ブラウザにサポート（参考: Can I use）されるようになって、1年が過ぎました。使用率も97%を超え、通常の案件に使用している人も多いと思います。 :is()疑似クラスは複数のセレクタを1つにまとめられて便利ですが、セレクタの末尾に使用すると、予想よりも多くの一致が発生するかもしれません。どんな場合にそうなるのかを紹介します。 たとえば、下記の.a .b .cと.a :is (.b . c)は同じように見えるかもしれませんが、実は異なります。 Using :is() in complex selectors selects more than you might initially think by Bramus CSSの:is()疑似クラスやセレクタの読む順番について詳しくは、以前の記事をご覧ください。 CSSの新しい疑似クラス:is()と:wher
