kandi X-RAY | count-ngram Summary

count-ngram is a Python library typically used in Security, Base64 applications. count-ngram has no bugs, it has no vulnerabilities and it has low support. However count-ngram build file is not available. You can download it from GitHub.

Count frequent n-gram from big data with limited memory. It processes 100GB text data within 23 hours on 8GB machine, yielding 1 million top frequent word n-grams. This implements Lossy Counting Algorithm [Manku and Motwani, 2002]. For people who are not familiar with natural language processing, an n-gram is a sequence of adjacent n words in corpus. Counting n-grams is an essential for language models, which perform important role in machine translation, speech recognition, optical character recognition, spelling correction and text input method.

How to convert base64-format audio files into .wav files without storage them on current directory in Python?

Asked 2022-Feb-28 at 03:48

I would like to know if there is a better way to convert base64-format audio files into .wav files without storage them on current directory.

The thing is that I get base64-format audio files from user uploading whith a POST request with FastAPI, then I decode them and convert them into .wav files because I need to pass the files over some functions that I created in order to preprocess and transcript the files and those functions use the wave module for .wav files. Due to I created .wav files for nothing more than transcripting them, so I don't need to store them and I finally delete them with os.unlink function.

As suggested by @martineau, try writing intermediately to an io.BytesIO, but after writing, call .seek(0) to return the steam position to the start, rather than calling getbuffer()
(after writing, the stream position will be at the end, ready for more data)

I miss having the ability to encode a query and have the same question. Nice work with finding out it's in base64.

I think reverse engineering is the only way to find out how things are encoded. For example, the stuff after the underlines is most likely binary-encoded.

Hello i'm having issue with uploading image to the cloud (Backblaze B2).

The problem is, when I use the example Thunder client to upload the file everything works fine and file is shown.

Now my problem is that when I upload with JS I don't know why it is corrupted or bugged. Like when I upload an image and download it, Windows File Manager says : file format not supported.

I decoded the file with base64 img decoder and it works fine and image is shown.

.readAsDataURL() converts the file it reads into Base64, so it can be represented as a URL you can put into a browser. A very long URL, but still a URL.

If you store a Base 64 representation of an image into a file on your machine, then try to read it with an image-display program, the operation will fail: "This doesn't look like a .jpg, .png, or .gif" so I don't know what to do with it." That's what your Windows file manager error message means.

If you want the file's contents raw rather than Base64 encoded, you'll need to use .readAsArrayBuffer().

The --skip-binary-as-hex option is to be used as an option to the mysql command when you open that from a shell prompt. It's not an option to be used within SQL syntax. See https://dev.mysql.com/doc/refman/8.0/en/mysql-command-options.html#option_mysql_binary-as-hex

Delphi - Amazon MWS API - How do derive the Base64 HMAC from the SHA 256 HMAC?

Asked 2021-Oct-30 at 20:29

Using:

Delphi 10.2.3 Tokyo
IPWorks SSL, IPWorks Encrypt

I'm writing a Delphi app to get order list from Amazon MWS API.

I've followed their instructions here:

https://docs.aws.amazon.com/general/latest/gr/signature-version-2.html

and here:

https://docs.developer.amazonservices.com/en_US/dev_guide/DG_SigningQueryRequest.html

But I am stuck at the signature generation process, specifically generating the Base64 HMAC.

I'm using IPWorks SSL components (Hash component) and am able to generate the SHA 256 signature based on the inputs. Upto this step everything is okay.

Its the next step that I am unable / unsure how to perform.

I'm using the Amazon scratchpad to generate the request and am seeing the request details, and the signatures generated: both SHA 256 and then the Base 64.

My Delphi code does not produce a Base 64 string like the one generated in the scratchpad. Please see the attached screen capture (sensitive information has been redacted).

This is my Delphi code to convert the SHA 256 string to Base 64:

That's because you don't understand the whole point of Base64 at all, including how to write it correctly. Its main purpose is to carry 8bit data (i.e. whole bytes) safely thru 7bit (i.e. ASCII):

When encoding 6bits are taken and displayed as one letter.
When decoding one letter is taken and 6bit of original data are restored.

Which is also the reason why encoding inflates the size by 1/3. When sending attachments in emails the former are stored in Base64, because emails are only 7bit safe. Which is the reason why sending a 4 MiB big picture ends up producing an email of at least 5.2 MiB.

No, it makes no sense to Base64 encode something that is already ASCII and as such 7bit safe. Everybody should be alarmed when someone wants him to Base64 encode the text 9660152e55a7178db9a9521cd80b7f4872f4be2290d1dd0f32205708f2e06589.

You want to encode bytes, not text. What you see is the hex representation of those bytes. You actually want this:
