QUESTION

Scanner doesn't update input when returning to method Java

Asked 2022-Apr-04 at 09:32

I'm writing a word-guessing game code. The main calls the inputTake method, which asks for input of a word consisting 5 English letters only, and returns is. Before returning the word, it calls another method, checkInput, to make sure the input is valid. If the input isn't valid, the checkInput method prints an error message and calls inputTake to let the user try again.

But when the first input is invalid, checkInput calls inputTake and then the second input is valid everything seems to work alright. The problem is that the method returns the first, invalid input, and not the valid input.

I tried initializing Scanner in the main and giving it to the method as parameter, but that doesn't help.

Below is the code I wrote, any thoughts? Any help is welcome

As mentioned in the comments, the problem is that your inputTake() call inside checkInput() doesn't do what you want. You can try this:

Chaum blind signature with blinding in JavaScript and verifying in Java

Asked 2022-Mar-04 at 16:01

I'm experimenting with Chaum's blind signature, and what I'm trying to do is have the blinding and un-blinding done in JavaScript, and signing and verifying in Java (with bouncy castle). For the Java side, my source is this, and for JavaScript, I found blind-signatures. I've created two small codes to play with, for the Java side:

ANSWER

Answered 2021-Dec-13 at 14:56

The blind-signature library used in the NodeJS code for blind signing implements the process described here:

BlindSignature.blind() generates the SHA256 hash of the message and determines the blind message m' = m * r^e mod N.
BlindSignature.sign() calculates the blind signature s' = (m')^d mod N.
BlindSignature.unblind() determines the unblind signature s = s' * r^-1 mod N.
BlindSignature.verify() decrypts the unblind signature (s^e) and compares the result with the hashed message. If both are the same, the verification is successful.

No padding takes place in this process.

In the Java code, the implementation of signing the blind message in signConcealedMessage() is functionally identical to BlindSignature.sign().
In contrast, the verification in the Java code is incompatible with the above process because the Java code uses PSS as padding during verification.
A compatible Java code would be for instance:

ANSWER

Answered 2022-Feb-10 at 21:28

There are two things you need to change in your formatter:

Use uuuu instead of yyyy. It's easy to try the latter, but y means "year within ERA". It doesn't know whether it's BC or AD. u means "year" including ERA information.
The default resolver style is SMART. Use .withResolverStyle(ResolverStyle.STRICT) to return a strict copy of the formatter.

can you give your

package.json
node version

I think that's because of the babel issue / your node version, because it cannot transpile the optional chaining https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Optional_chaining

maybe tried using latest LTS node version? because as far as I know, the latest LTS node version already support optional chaining

Vue 3: Module '"../../node_modules/vue/dist/vue"' has no exported member

Asked 2022-Jan-24 at 08:38

After updating my npm packages, some of the imports from the 'vue' module started showing errors:

TS2305: Module '"../../node_modules/vue/dist/vue"' has no exported member 'X'

where X is nextTick, onMounted, ref, watch etc. When serving the project, Vue says it's "failed to compile". WebStorm actually recognizes the exports, suggests them and shows types, but the error is shown regardless. Some exports like computed and defineComponent work just fine.

What I've tried:

Rollback to the previously used Vue version "3.2.2" > "3.0.11". It makes the abovementioned type errors disappear, but the app stops working entirely, showing lots of TypeError: Object(...) is not a function errors in console and not rendering the app at all. In the terminal, some new warnings are introduced: "export 'X' (imported as '_X') was not found in 'vue' where X is createElementBlock, createElementVNode, normalizeClass and normalizeStyle.
Rollback other dependencies. None of the ones that I tried helped fix the problem, unfortunately.
Manually declare the entirety of 'vue' module. We can declare the 'vue' module exports in shims-vue.d.ts, and it actually makes the errors disappear, however, this seems like a terrible, time-consuming workaround, so I would opt out for a better solution if possible.

ANSWER

Answered 2021-Aug-15 at 13:53

That named exports from composition API are unavailable means that vue is Vue 2 at some place which has only default export. Since Vue 3 is in dependencies and both lock file and node_modules were refreshed, this means that Vue 2 is nested dependency of some direct dependency.

The problem needs to be investigated in lock file. It shows that @vue/cli-plugin-unit-jest@4.5.13 depends on vue-jest@3 which depends on vue@2.

A possible solution is to upgrade @vue/cli-plugin-unit-jest to the latest version, next. The same likely applies to other @vue/cli-* packages because they have matching versions.

QUESTION

Powershell FileSystemWatcher script firing twice on some new files

Asked 2022-Jan-18 at 12:36

I'm using FileSystemWatcher to monitor a folder where documents are scanned to. When a new file is detected, it will send an email to notify someone. It's working as is, but sometimes (not every file) it will trigger 2 or 3 times on a new file and send the email 2-3 times for the same file. I'm guessing it has to do with the way the file is created by the scanner or something like that.

I'm trying to figure out a way to protect against this happening, to ensure it only sends one email per file. Any suggestions would be greatly appreciated.

This may be because you listen too many notifications. The default is LastWrite, FileName, and DirectoryName FileName is sufficient for your need and may prevent your issue.

ANSWER

Welcome @Backup Gov18,

This is a documented issue.

Note: Only one active BarCodeScanner preview is supported currently. When using navigation, the best practice is to unmount any previously rendered BarCodeScanner component so the following screens can use without issues.

There is a workaround.

Instead of conditionally rendering the component, you could render it inside another dedicated screen component.

This way, after this new screen reads the barcode, you could navigate back to your first screen. Navigating back may unmount this new screen. You can force unmount if you need to.

As you are using react-navigation, you had better use .pop() instead of goBack().

Alternative

You can also use expo-camera instead of expo-barcode-scanner. expo-camera does not have this issue. It also offers more options like flashlight/torch and switching cameras.
