Example 1: syntax error: ; expected Console . WriteLine ( "Hello World" ) Example 2: else js declaration or statement expected // This example shows that you need to wrap your line in parenthesis. // This is the syntax for destructuring after declaration as shown in the example here: let x0 , x1 , y0 , y1 ; if ( this . props . viewport ) { ( { x0 , x1 , y0 , y1 } = this . props . viewport ) ; }

Answer : I had the same exact issue. Looks like you're missing drivers for the Ethernet. Go to this link (which is from the actual Ethernet provider): https://www.realtek.com/en/component/zoo/category/network-interface-controllers-10-100-1000m-gigabit-ethernet-pci-express-software Download the "2.5G Ethernet LINUX driver r8125 for kernel up to 5.6" and follow the installation instructions. You should be able to use wired connection once you're done. The rtl8125b support has been added to the linux-next tree 6 days ago. https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/drivers/net/ethernet/realtek?h=next-20200720&id=0439297be95111cf9ef5ece2091af16d140ce2ef It will take some time to get into stable and then into Ubuntu. You can try to install drivers from the Realtek site before Linux supports it natively. You'll need to disable Secure Boot in BIOS and blacklist r8169 to get them working. The issue is fixed in the 5.9 kern...

Answer : pyInstaller is cross-platform and very powerful, with many third-party packages (matplotlib, numpy, PyQT4, ...) specially supported "out of the box", support for eggs, code-signing on Windows (and a couple other Windows-only goodies, optional binary packing... the works!-) The one big issue: the last "released" version, 1.3, is ages-old -- you absolutely must install the SVN trunk version, svn co http://svn.pyinstaller.org/trunk pyinstaller (or the 1.4 pre-release, but I haven't tested that one). A fair summary of its capabilities as of 6 months ago is here (in English, despite the Italian URL;-). cx_Freeze is cross-platform and does the same, or you could use py2app, which works on mac only. Here's a list of them. Py2exe PyInstaller cx_Freeze bbfreeze py2app You might also consider Nuitka, which compiles python to native code.

Answer : No python does not use its own encoding. It will use any encoding that it has access to and that you specify. A character in a str represents one unicode character. However to represent more than 256 characters, individual unicode encodings use more than one byte per character to represent many characters. bytearray objects give you access to the underlaying bytes. str objects have the encode method that takes a string representing an encoding and returns the bytearray object that represents the string in that encoding. bytearray objects have the decode method that takes a string representing an encoding and returns the str that results from interpreting the bytearray as a string encoded in the the given encoding. Here's an example. >>> a = "αά".encode('utf-8') >>> a b'\xce\xb1\xce\xac' >>> a.decode('utf-8') 'αά' We can see that UTF-8 is using four bytes, \xce, \xb1, \xce, and \xac to repr...

Answer : Turns out, the best way to handle this is to make the following change in android/app/build.gradle : android { compileSdkVersion 26 buildToolsVersion '26.0.3' lintOptions { disable 'InvalidPackage' } defaultConfig { applicationId "com.example.app" minSdkVersion 16 targetSdkVersion 26 versionCode 1 versionName "1.0" testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" } signingConfigs { release { keyAlias keystoreProperties['keyAlias'] keyPassword keystoreProperties['keyPassword'] storeFile file(keystoreProperties['storeFile']) storePassword keystoreProperties['storePassword'] } } // This is the main section that I've updated // to get the release APK to build buildTypes { release { profi...

Answer : The only way to check code is by trying to redeem it. After entering the code, if the code is valid, there will be a confirmation step, and you can cancel the operation. If the code is invalid or expired it will be rejected immediately with an error message.

Answer : LL(0) parsers do look at the tokens, but they don't decide which productions to apply upon them. They just determine if the sequence belongs to the language or not. This means that every non-terminal symbol must have a single right-hand side and that there may be no recursion. G == ID name lastname name == STRING lastname == STRING # lexer rules # ----------- ID == [0-9]+ STRING == <unicode>+ Note that, as mentioned by @280Z28, a separate lexer is needed to deal with the variable length parts ( ID and STRING ), or the grammar will not be LL(0) . The sequence of productions to apply to parse an input with that grammar requires zero lookahead. A lookahead is required for determinism when there's more than one production that could be applied after part of the given input sequence has been parsed. In theory, a grammar generates a language, and, in that, ambiguity (having more than one way to derive a given phrase) is fine. In parsing, having one-and-...

Answer : Simple. Just call puts 'your debug message' and it will be printed to where the server is logging. For instance, if you are running the rails server only by running rails s on a terminal, the output of puts will be on this same terminal. If you need more 'power' to debug, you should consider using IDE's like RubyMine to debug your code. Thus, you can place breakpoints and see all the application state. You can use console.log() in your views: #view.html.erb <script> console.log("Message"); </script> If you want to log in your Model, try: Rails.logger.debug "message!!"
