    How is it that 20 years after @Microsoft lost the IE lawsuit, @Apple is allowed to prevent the installation of any other browser on iOS ?

    I prefer function foo(bar) { ... } over const foo = (bar) => { ... } #JavaScript #TypeScript

    Important takeaways: 1. Gaza wasn't an open air prison 2. Don't start a war with your much stronger neighbor in the most hideous way possible 3. Don't build your military infrastructure intentionally under the civilian infrastructure

    Wow! Just wow! What about 200,000 Israelis currently displaced from their homes in Northern Israel and around Gaza? What about the fact that it's Hezbollah and Hamas in Lebanon instigating this fighting? What about Hezbollah fighters stationed and firing on the Israeli border

    How do you identify a modern Web app? It has multiple small spinners instead of one big spinner.

    When Britain invaded Iraq did they or didn't they fight in and bomb areas where civilians also resided? During WW2 how many German cities did Britain bomb? If Ireland starts firing repeated barrages of rockets at London from within Dublin what would the British response be?

    Funny 😄 But I would like to see hotels disrupted: 1. No need for concierge - I can get the same info from Google 2. No need for human reception - let me scan an id and get the key card 3. Internal website for room service, house keeping, etc 4. No need for phone in the room ...
