Hello - Many of you will have heard the sad news of Dave Walden’s passing. Katie Hafner wrote an obituary for the New York Times <https://www.nytimes.com/2022/05/03/technology/david-walden-dead.html?unlocked_article_code=AAAAAAAAAAAAAAAACEIPuomT1JKd6J17Vw1cRCfTTMQmqxCdw_PIxftm3iWka3DIDm4ZiPgYCIiG_EPKarska9It3jjeW9ZFPLIpAfB_x-MZP1BoT0PghKq4r6k_And_r5OvDCRx1ojRXLs8_HjmNWDneLx1nfjl5R7bdWW5DaLAgiB1LBJlqZphIVyt0CcPk6nVA6UijIkFqPQlDp97RjgEZDDb_KW7TkUjZ6jVK03U-QI0WOpGWD3MnNT66LgIcwRaCVuuX2ooqC9nq4saYIVLSf65ex0we8P-gqETDXhqL-qpBZ4xTovXltZ6oC5T3hAGofOumWmRLTb39V4%E2%88%A3=em-share>.
