kandi X-RAY | murmur Summary

murmur is a Java library typically used in Messaging applications. murmur has no bugs, it has no vulnerabilities, it has build file available and it has low support. However murmur has a Non-SPDX License. You can download it from GitHub.

Murmur (formerly project Rangzen) is an open-source, anonymous messaging app that does not require an Internet connection. Messages are not sent in real-time like with other messaging apps that rely on the Internet and have a central server, but instead spread directly from one device to another (forming a peer-to-peer network) without user intervention using Bluetooth and WiFi Direct. The more devices the faster the message spreads! If no device is around, the message is queued in the feed to be sent later. You control your anonymity and decide what information to share about yourself. Lastly, Connection Scores help you filter spam messages and Restricted Messages limit your audience to your friends.

            Can not create ReadWrite filesystem in kubernetes (ReadOnly mount)
            Asked 2021-Dec-31 at 04:17

            I currently am in the process of learning kubernetes, as such I have decided to start with an application that is simple (Mumble).


            My setup is simple, I have one node (the master) where I have removed the taint so mumble can be deployed on it. This single node is running CentOS Stream but SELinux is disabled.

            The issue

            The /srv/mumble directory appears to be ReadOnly, and at this point I have tried creating an init container to chown the directory but that fails due to the issue above. This issue appears in both containers, and I am unsure at this point how to change this to allow the mumble application to create files in said directory. The mumble application user runs as user 1000. What am I missing here?

            Configs ...


            Answered 2021-Dec-31 at 04:17

            command: ["sh", "-c", "chown -R 1000:1000 /srv/mumble"]

            Not the volume that is mounted as read-only, the ConfigMap is always mounted as read-only. Change the command to:

            command: ["sh", "-c", "chown 1000:1000 /srv/mumble"] will work.



            Google Translate web gives two different translations (chrome browser vs Selenium/chromedriver)
            Asked 2021-Dec-19 at 21:41

            I'm having a similar issue to this question, but with German. When I use a Chrome browser on my pc I get one translation (from, but with Selenium (in headless mode) I get a different translation.

            As an example, the following text gives two different results:

            • "Im Studienzimmer herrscht ein leises Murmeln der Studenten und ein etwas lauteres zischen der Chemikalien."
            1. Using Chrome browser:

              • "In the study room there is a soft murmur from the students and a somewhat louder hiss of the chemicals."
            2. Using Selenium:

              • "In the study room there is a quiet marbles of the students and a slightly louder hiss of the chemicals."

            Why does German "Murmeln" get translated as 'murmur' by the translation using Chrome browser, but as 'marbles' when accessing the same page using Selenium?

            How to access json file data from js file
            Asked 2021-Jul-06 at 15:03

            I'm developing a discord bot and i wanted to send a random sentence from my dactylo.json file when the user sends a specific message. However, when trying to access data from this file, I get an "undefined" error like it couldn't read my json file. I looked over many previous questions but couldn't find an answer that helped me, even though it helped other people. I'm sure I'm missing something but I can't seem to find what...

            Implement a "Find all" algorithm that displays matched lines in a table, and jumps to line when table cell clicked
            Asked 2021-Mar-13 at 15:14

            I would like to implement functionality for being able to search a QPlainTextEdit for a query string, and display all matched lines in a table. Selecting a row in the table should move the cursor to the correct line in the document.

            Below is a working example that finds all matches and displays them in a table. How can I get to the selected line number in the string that the plaintextedit holds? I could instead use the match.capturedEnd() and match.capturedStart() to show the matches, but line numbers are a more intuitive thing to think of, rather than the character index matches.

            MWE (rather long sample text for fun) ...


            Answered 2021-Mar-13 at 15:14

            In order to move the cursor to a specified position, it's necessary to use the underlying QTextDocument using document().
            Through findBlockByLineNumber you can construct a QTextCursor and use setTextCursor() to "apply" that cursor (including the actual caret position) to the plain text.

            Best performing way to emulate integer overflow?
            Asked 2020-Sep-02 at 00:00

            I'm mucking about with hash functions, porting some classics like murmur or fnv families and creating my own, for fun, really. I know js isn't exactly an ideal environment for this but whatever.

            The biggest obstacle I run into is the fact that js uses doubles for most arithmetics. Almost every single hash function I've ever seen exploits integer overflow by multiplication. For example, I take the input of 7 and multiply it by some big prime like 0x5bd1e995, this multiplication amplifies the significance of that little input into every single bit of the result which is really neat for hash functions.

            Unfortunately this falls totally flat when using doubles to do the math because doubles won't overflow like integers (preserving least significant bits) but instead attempt to preserve the magnitude of the result (preserving most significant bits) and that screws with the design of almost any hash function.

            The few ways I've found to deal with this are to

            1. Modulo the input before multiplying to make sure the result doesn't exceed Number.MAX_SAFE_INTEGER
            2. Do the multiplication after splitting the input into two 16 bit values and recombine
            3. Use a variety of magic numbers depending on the input to make sure I stay in doubles range of integers

            Problem is though, none of these are fast and cut the performance into shreds. So, question time: Is there a well performing way to emulate integer overflow behavior in js in case of a multiplication that will almost definitely exceed Number.MAX_SAFE_INTEGER?



            Answered 2020-Sep-02 at 00:00

            Please look into Math.imul.

            This multiplies numbers as 32bit ints and simply truncates the overflow bits.



            ghc error: hidden package, but it's actually exposed

            I'm trying to use the package Parsec. When I run ghc Main.hs I get the error message:



            Answered 2020-Aug-05 at 18:57

            This looks like an issue with global vs local installs. Oh, and there it is in your ghc-pkg list output. You've got a multiuser ghc install and a single-user list of packages you've installed. Things work when you run ghc as a superuser because they won't see your local (per-user) installs.

            This is going to cause problems unless you use a tool to manage your environment for you. Both cabal and stack can handle this fine. I prefer cabal because it doesn't need coaxing to work with your preinstalled GHC, but this is a matter that has caused religious wars in the past. I won't argue against stack if you have a good resource for using it instead.

            This line in unload while(cursor->next != NULL) provokes the seg fault when table[i] is not populated. If no words are in that index, there is no such thing as cursor->next.



            Fastest Way to Find the Dot Product of a Large Matrix of Vectors
            Asked 2020-Jun-26 at 23:23

            I am looking for suggestions on the most efficient way to solve the following problem:

            I have two arrays called A and B. They are both of shape NxNx3. They represent two 2D matrix of positions, where each position is a vector of x, y, and z coordinates.

            I want to create a new array, called C, of shape NxN, where C[i, j] is the dot product of the vectors A[i, j] and B[i, j].

            Here are the solutions I've come up with so far. The first uses the numpy's einsum function (which is beautifully described here). The second uses numpy's broadcasting rules along with its sum function.

            With a bit of reshaping, we can use matmul. The idea is to treat the first 2 dimensions as the 'batch' dimensions, and to the dot on the last:

Is Github adding something I don't know of? Or what do you think could be the problem?

            This is likely caused by case sensitivity. On line 7 of UserController.js you require ./User but the file is titled user.js. Heroku is likely case insensitive, whereas your file system is not. I imagine capitalizing the file name, or changing the require to all lowercase should resolve your issue here.
