WebVM lets you run a full Linux system directly in your web browser without needing a server. It uses a special engine called CheerpX to safely run unmodified Linux programs by converting x86 code to WebAssembly. You get a real Debian Linux environment with many tools, and it supports networking through Tailscale VPN, so your browser VM can connect securely to the internet. You can also customize and deploy your own WebVM easily using GitHub, making it great for development, testing, or learning Linux without installing anything. This means you can have a powerful, private Linux machine anytime, anywhere, just in your browser[1][2][3].

🚀 Вышел стабильный JavaScript движок от Google для Android
Новая стабильная библиотека Jetpack JavaScript Engine позволит разработчикам выполнять JS код в изолированной и ограниченной среде.
class MainActivity : ComponentActivity() {
// Теперь nullable, без lateinit
private var jsSandbox: JavaScriptSandbox? = null
private var jsIsolate: JavaScriptIsolate? = null
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
if (!JavaScriptSandbox.isSupported()) {
Log.e("JS", "JavaScriptSandbox не поддерживается")
return
}
lifecycleScope.launch {
// Создаём и сохраняем в nullable-поле
jsSandbox = JavaScriptSandbox
.createConnectedInstanceAsync(applicationContext)
.await()
jsIsolate = jsSandbox?.createIsolate()
// При выполнении гарантируем, что jsIsolate != null
val result: String = jsIsolate
?.evaluateJavaScriptAsync(JS_SCRIPT_SCRING)
?.await()
?: "Ошибка: isolate не инициализирован"
Log.d("JS", "Результат выполнения: $result")
}
}
override fun onDestroy() {
super.onDestroy()
// Закрываем только если не null
jsIsolate?.close()
jsSandbox?.close()
}
}
