QUESTION

Can not create ReadWrite filesystem in kubernetes (ReadOnly mount)

Asked 2021-Dec-31 at 04:17

Summary

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

Setup

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 ...

ANSWER

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 https://translate.google.com), 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."

Using Chrome browser:
- "In the study room there is a soft murmur from the students and a somewhat louder hiss of the chemicals."
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?

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) ...

ANSWER

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.

QUESTION

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

Modulo the input before multiplying to make sure the result doesn't exceed Number.MAX_SAFE_INTEGER
Do the multiplication after splitting the input into two 16 bit values and recombine
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?

Please look into Math.imul.

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

ANSWER

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.

The problem is that when I download the Github project and try the exact same deploy strategy the result is different. The downloaded files are running fine locally, but Heroku don't like them.

ANSWER

Answered 2020-Jun-01 at 12:53

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.
