will help you You are (somewhere) rounding your converted kilogram value.
180 * 0.45359237 is 81.6466266, that's fine.

Does that help It's worth disabling plug-ins that you don't use, but not to save memory. Disabling them will give you cleaner UI without unnecessary menu options and settings.
Performance wise, you will not gain much on a modern hardware as IDEA uses lazy loading and initialization, it will not load plug-ins that are not used in the current project.

wish helps you You'll want the g modifier for format that drops insignificant zeroes;
code :
>>> "{0:.6g}".format(5.5657188485)
'5.56572'
>>> "{0:.6g}".format(3.539)
'3.539'
>>> for i in a:
...    print '%.6g' % (i,)
...

Hope this helps I recently had to run pod repo update and the job again ran for 8+ hours and now consumed 38GB of disk space on the linked SD card.
I managed to free up enough space on my internal disk to experiment with removing the symlinked ~/.cocoapods directory and that resulted in much more acceptable behavior. Without the symlink, the disk usage drops drastically to:
code :
$ cd ~/.cocoapods/repos/master
$ du -d 1 -h
420M    ./.git
538M    ./Specs
959M    .
Wrong amount of significant bytes when decrypting AES CFB with CryptoJS

Wrong amount of significant bytes when decrypting AES CFB with CryptoJS

wish helps you I found the answer myself. The problem is actually not in the javascript code. It was in the Python code, which encrypted the data.
When setting the segment size to 128 in pycrpyto using AES CFB you have to pad your date to crypt it to be a multiple of 16 bytes.
code :
length = 16 - (len(data) % 16)
data += bytes([length]) * length

iv = Random.new().read(AES.block_size)
key = options.encrypt_key.encode()
cipher = AES.new(key, AES.MODE_CFB, iv, segment_size=128)

crypted = cipher.encrypt(data)
entry = iv + crypted
entry = base64.b64encode(entry)
var base64data = CryptoJS.enc.Base64.parse(data);

var encrypted = new CryptoJS.lib.WordArray.init(base64data.words.slice(4));
var iv = new CryptoJS.lib.WordArray.init(base64data.words.slice(0, 4));

var cipher = CryptoJS.lib.CipherParams.create({ ciphertext: encrypted });

var decrypted = CryptoJS.AES.decrypt(cipher, key, {iv: iv, mode: CryptoJS.mode.CFB});
