QUESTION

Is there any (invertible) way (in c#) to convert a string into a smaller one, and when I say smaller I mean "with reduced length"?

Asked 2022-Apr-16 at 07:31

Let me explain: in my use case a system gives me many strings that can vary in size (number of characters; length), sometimes it can be really huge! The problem is that I have to save this string in a column of a table of a "SQL Server" database, the bad news is that I am not allowed to do any migration in this database, the good news is that the column already has type nvarchar(max).

I've done some research before and followed the following post to write a data compressor using "Gzip" and "Brotli".

ANSWER

Answered 2022-Apr-15 at 13:55

The max size for a column of type NVARCHAR(MAX) is 2 GByte of storage.

Since NVARCHAR uses 2 bytes per character, that's approx. 1 billion characters.

So I don't think you actually need to make a compression, if the problem is the performance when retrieving data, then you can use a server side caching system.

You have to add the SocialLoginModule to the imports

also the version you have based on the package.json you use are using version 4 which is for angular 12, you will have to use version 3 for angular 10

Also remove the service from exports. Services are provided.

Looking at the strace output for both root and greg, the problem seems clear.

For the root user, python 3.6 finds the libraries in /usr/lib64/python3.6.

However, for greg, it only looks under /usr/bin/python3 for subdirectories. That doesn't work because /usr/bin/python3 is a file.

I suspect that the user greg has PYTOHNHOME set erroneously to the location of the Python binary , and that is causing the issue.

Remove PYTOHNHOME from your environment, log out and log in again.

Note: the stuff below is probably barking up the wrong tree. I'll leave it for information.

The encodings module is an (undocumented) part of the python standard library. It is used by the locale module.

Based on the output I suspect that your Python installation has been damaged or corrupted. Try re-installing python.

EDIT:

If a forced re-install doesn't fix the problem, check that the directory encodings exist in your Python stdlib directory, and is accessible for all users.

QUESTION

Vuejs Webpack Compression Plugin not compressing

Asked 2022-Mar-28 at 12:53

I need help debugging Webpack's Compression Plugin.

SUMMARY OF PROBLEM

Goal is to enable asset compression and reduce my app's bundle size. Using the Brotli algorithm as the default, and gzip as a fallback for unsupported browsers.
I expected a content-encoding field within an asset's Response Headers. Instead, they're loaded without the field. I used the Chrome dev tools' network tab to confirm this. For context, see the following snippet:
No errors show in my browser or IDE when running locally.

WHAT I TRIED

Using different implementations for the compression plugin. See below list of approaches:
1. (With Webpack Chain API)

ANSWER

Answered 2021-Sep-30 at 14:59

It's not clear which server is serving up these assets. If it's Express, looking at the screenshot with the header X-Powered-By, https://github.com/expressjs/compression/issues/71 shows that Brotli support hasn't been added to Express yet.

There might be a way to just specify the header for content-encoding manually though.

QUESTION

Why do browsers (chromium-based and firefox) prefer gzip over brotli?

Asked 2022-Mar-14 at 17:31

I have tested a few browsers (namely firefox, edge, chrome and chromium, in their mobile and desktop versions) and found that each of them sent the following accept-encoding header value: gzip, deflate, br when performing a request.

According to the doc, this header field consists of a list of encodings supported by the browser, in order of preference. What surprises me is that brotli (br) is listed last, which means that it is less likely to be the selected algorithm for content-encoding than gzip even though it should achieve a better compression ratio.

Is there a specific reason as to why browser tends to prefer gzip over brotli ?

...

ANSWER

Answered 2022-Mar-14 at 17:31

I am not seeing anywhere in the specifications that the ordering has any meaning. To the contrary, I see that a preference can only be expressed by providing quality weights for the encoding, and that providing such preferences from the client side is discouraged. It is up to the server to pick among the choices that the client can accept, however it likes.

QUESTION

No such file or directory: '/opt/anaconda3/lib/python3.8/site-packages/rtree/lib'

Asked 2022-Mar-13 at 16:13

I am trying to build an app from a python file (Mac OS) using the py2app extension. I have a folder with the python file and the "setup.py" file.

I first tested the app by running python setup.py py2app -A in the terminal and the dist and build folder are successfully created and the app works when launched.
Now when I try to build it non-locally by running the command python setup.py py2app in the terminal, there are various "WARNING: ImportERROR" messages while building and finally a error: [Errno 2] No such file or directory: '/opt/anaconda3/lib/python3.8/site-packages/rtree/lib' error.

How can I fix this? I've tried to delete anaconda fully as I don't use it but it seems to still want to run through it. Additionally, I have tried to run the build command using a virtual environment but I end up having even more import errors.
*I Left out a lot of the "skipping" and "warning" lines using "..." for space

ANSWER

Answered 2022-Mar-13 at 16:13

The error error: [Errno 2] No such file or directory: '/opt/anaconda3/lib/python3.8/site-packages/rtree/lib' was caused by py2app trying to build the program bundle using a non-existent interpreter. This means that even if you try to uninstall a manager like Anaconda, it still has option logs somewhere on your mac.

The fix:

Open the terminal and type the command type -a python.

curl: (94) An authentication function returned an error when trying to perform SMTP diagnostics

Asked 2022-Mar-12 at 01:33

I am trying to perform SMTP diagnostics using curl and am getting this error: "curl: (94) An authentication function returned an error". Googling this error doesn't return much other than the generic error list and descriptions.

I am using the curl client that comes with Git on Windows 10, and have tried running this from both Gitbash and the normal Command Line. The mail server is a corporate server at the overseas headquarters and we don't have easy access to the configuration or logs. It does require SSL/TLS for the connection.

ANSWER

Answered 2022-Mar-11 at 14:52

I'm not familiar with the SMTP feature of curl, but I know quite a bit about SMTP. curl apparently failed to authenticate. I haven't found a documentation about which authentication mechanisms it supports, but GSSAPI doesn't seem to be one of them (at least not with the options that you specified). (I know nothing about GSSAPI either.)

My guess about what went wrong is that you're not using TLS with curl (STARTTLS is still listed as one of the supported extensions). What I take from this documentation is that you should either specify --ssl or --ssl-reqd, or change smtp to smtps (smtps://mymailserver.com), which switches from Explicit TLS to Implicit TLS. The list of supported authentication mechanisms often changes once TLS is enabled and will likely include PLAIN afterwards.
