Answer : No, not directly. Arduinos just don't have the horsepower to do such a task. For this project, I would recommend using a Raspberry Pi. Take a look at this awesome blog post by Joonas Pihlajamaa on using a Raspberry Pi as a Arduino HDMI shield. Please see Chrontel's products at www.chrontel.com: CH7035 - TTL to HDMI output. CH7026 - TTL to CVBS. CH7033 - TTL to VGA and HDMI. CH7034 - TTL to VGA. CH7322 - HDMI CEC. Their TTL input supports RGB 8-8-8. 5-6-5, YCrCb 4:2:2, ITU656, etc. I think the Arduino can use their MCU interface to write graphics data to their frame buffer directly. On-chip scaler can scale frame buffer content to all HDMI output resolutions like 1080P.

Answer : Yes, it works fine. You need <security:global-method-security pre-post-annotations="enabled" /> in ...-servlet.xml . It also requires CGLIB proxies, so either your controllers shouldn't have interfaces, or you should use proxy-target-class = true . See Spring Security FAQ (emphasis mine). In a Spring web application, the application context which holds the Spring MVC beans for the dispatcher servlet is often separate from the main application context. It is often defined in a file called myapp-servlet.xml, where “myapp” is the name assigned to the Spring DispatcherServlet in web.xml. An application can have multiple DispatcherServlets, each with its own isolated application context. The beans in these “child” contexts are not visible to the rest of the application. The “parent” application context is loaded by the ContextLoaderListener you define in your web.xml and is visible to all the child contexts. This parent context is u

Example 1: js array to json // Array to JSON: const jsonString = JSON . stringify ( yourArray ) ; // JSON to Object / Array const yourData = JSON . parse ( jsonString ) ; Example 2: Javascript object to JSON string var person = { "first_name" : "Tony" , "last_name" : "Hawk" , "age" : 31 } ; var personJSONString = JSON . stringify ( person ) ;

Answer : You can use a button tag instead of input <button type="submit" class="btn btn-primary"> <i class="icon-user icon-white"></i> Sign in </button> I think you can use label tags for this purpose. Here is a sample of the twitter bootstrap HTML navbar: <form class="navbar-search"> <input type="text" class="search-query" placeholder="Search here" /> <label for="mySubmit" class="btn"><i class="icon-search icon-white"></i> Search me</label> <input id="mySubmit" type="submit" value="Go" class="hidden" /> </form> Basically you get a label element for the input (type=submit) and then you hide the actual input submit. Users can click on the label element and still get through with the form submission. I think you should try this FontAwesome designe

Answer : Get the container ID and run the command. docker exec -it container_id python manage.py createsuperuser I recommend adding a new management command that will automatically create a superuser if no Users exist. See small example I created at https://github.com/dkarchmer/aws-eb-docker-django. In particular, see how I have a python manage.py initadmin which runs: class Command(BaseCommand): def handle(self, *args, **options): if Account.objects.count() == 0: for user in settings.ADMINS: username = user[0].replace(' ', '') email = user[1] password = 'admin' print('Creating account for %s (%s)' % (username, email)) admin = Account.objects.create_superuser(email=email, username=username, password=password) admin.is_active = True admin.is_admin = True admin.save() else: print(

Answer : You can just use Eloquent::insert() . For example: $data = array( array('name'=>'Coder 1', 'rep'=>'4096'), array('name'=>'Coder 2', 'rep'=>'2048'), //... ); Coder::insert($data); We can update GTF answer to update timestamps easily $data = array( array( 'name'=>'Coder 1', 'rep'=>'4096', 'created_at'=>date('Y-m-d H:i:s'), 'modified_at'=> date('Y-m-d H:i:s') ), array( 'name'=>'Coder 2', 'rep'=>'2048', 'created_at'=>date('Y-m-d H:i:s'), 'modified_at'=> date('Y-m-d H:i:s') ), //... ); Coder::insert($data); Update: to simplify the date we can use carbon as @Pedro Moreira suggested $now = Carbon::now('utc')->toDateTimeString(); $data = array(

Example 1: size array python size = len ( myList ) Example 2: python get array length # To get the length of a Python array , use 'len()' a = arr . array ( ‘d’ , [ 1.1 , 2.1 , 3.1 ] ) len ( a ) # Output : 3 Example 3: find array length python array = [ 1 , 2 , 3 , 4 , 5 ] print ( len ( arr ) ) Example 4: python array length len ( my_array ) Example 5: find array length in python a = arr . array ( 'd' , [ 1.1 , 2.1 , 3.1 ] ) len ( a ) Example 6: python get array length # new array in range 1 -> 10 ; ar = [ i for i in range ( 1 , 10 ) ] print ( len ( ar ) ) # OR print ( len ( [ 1 , 2 , 3 ] ) )

Answer : Always working workaround (Manual download) Download directly from Apple: Latest Release version or Latest Beta version or Any version you need. And all other downloadable contents Then extract and move it where you like. This has so many benefits comparing to appstore update. (like the ability to resume download, not replacing the old one, not wasting hidden directories and etc.) Note that you should use safari to download it. Apple suggested workaround (Force App Store to redownload) Since This is Known Issues Xcode may fail to update from the Mac App Store after updating to macOS Catalina. (56061273) Apple suggest this: To trigger a new download you can delete the existing Xcode.app or temporarily change the file extension so it is no longer visible to the App Store.

Answer : Configuration files can't be linked together from a configuration directive. However HAProxy can load multiple configuration files from its command line, using the -f switch multiple times: haproxy -f conf/http-defaults -f conf/http-listeners -f conf/tcp-defaults -f conf/tcp-listeners If you want to be flexible with the amount of config files you can even specify a directory like this: -f /etc/haproxy . The files will then be used in their lexical order, newer files overriding older files. See the mailing list for an example, if provides links to the documentation. This information can be found in the management guide, not the regular docs. Stumbled on this answer where the author created scripts to imitate nginx disable enable sites functionality. In the haproxy init.d startup he uses script loop to build the haproxy -f commands concatenation. /etc/init.d/haproxy: EXTRAOPTS=`for FILE in \`find /etc/haproxy/sites-enabled -type l | sort -n\`; do CONFIGS=&quo

Example 1: Nested dictionary Python IDs = [ 'emp1' , 'emp2' , 'emp3' ] EmpInfo = [ { 'name' : 'Bob' , 'job' : 'Mgr' } , { 'name' : 'Kim' , 'job' : 'Dev' } , { 'name' : 'Sam' , 'job' : 'Dev' } ] D = dict ( zip ( IDs , EmpInfo ) ) print ( D ) # Prints {'emp1': {'name': 'Bob', 'job': 'Mgr'}, # 'emp2': {'name': 'Kim', 'job': 'Dev'}, # 'emp3': {'name': 'Sam', 'job': 'Dev'}} Example 2: Nested dictionary Python D = { 'emp1' : { 'name' : 'Bob' , 'job' : 'Mgr' } , 'emp2' : { 'name' : 'Kim' , 'job' : 'Dev' } , 'emp3' : { 'name' : 'Sam' , 'job' : 'Dev'

Answer : OK, found the answer by browsing sequelize source code : https://github.com/sequelize/sequelize/blob/master/lib/dialects/postgres/connection-manager.js#L39 To activate SSL for PG connections you don't need native: true or ssl: true but dialectOptions.ssl: true so the following did finally work: sequelize = new Sequelize(process.env.DATABASE_URL, { dialect: 'postgres', protocol: 'postgres', dialectOptions: { ssl: true } }); You no longer need to parse the DATABASE_URL env variable, there is a Sequelize constructor which accepts the connection URL: sequelize = new Sequelize(process.env.DATABASE_URL, { dialect: 'postgres', protocol: 'postgres', dialectOptions: { ssl: true } }); One needs to add dialectOptions under ssl "development": { "username": process.env.DB_USERNAME, "password": process.env.DB_PASSWORD, "database": proce
