EdgeVPN lets you create secure, decentralized private networks using peer-to-peer (p2p) connections without relying on central servers. It can build a VPN that automatically assigns IPs, includes a small DNS server, and protects your network even if tokens leak. You can also use it as a reverse proxy to share TCP services or send files securely over p2p without a VPN connection. It works well for edge devices and development, especially behind NATs, and can be integrated into your own Go programs. This helps you connect devices easily and securely across different networks without complex setup or infrastructure.

🚀 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()
}
}
