Make sure your tv supports cec and that it is enabled. Tv manufactures call CEC by different names so you may have to do some research depending on your brand.
Make sure you are using a new hdmi cable that is at least HDMI 1.2a
Different names for HDMI CEC
Samsung – Anynet+
Sony – BRAVIA Link or BRAVIA Sync
Sharp – Aquos Link
Hitachi – HDMI-CEC
AOC – E-link
Pioneer – Kuro Link
Toshiba – Regza Link or CE-Link
Onkyo – RIHD (Remote Interactive over HDMI)
LG – SimpLink
Panasonic – VIERA Link or HDAVI Control or EZ-Sync
On nx, I’m used to xargs which allows to convert from a pipe of output into arguments passed to a command. This is useful, as many commands only accept arguments as parameters.
After watching an autologon system not logging on automatically over the past years, the pattern seems to be that at least major, and some less minor Windows updates remove autlogon parts of the registry.
I’m not sure where the boundary between “major” and “less minor” lies (though I suspect “cumulative updates” and larger), nor if more than these values are affected:
value name AutoAdminLogon gets removed or becomes value 0
value DefaultUserName gets removed
value DefaultPassword gets removed
This means that now after each startup, I need to schedule a task that runs a script setting the values I need depending if a password is needed or not.
The script also needs credentials, so I need to figure out how to properly do that.
For several reasons, mostly security-related, PowerShell scripts aren’t as easily portable and usable as batch scripts can be. However, we can bundle a batch script with our PowerShell scripts to work around these issues. Here, we’ll show you a few of those problem areas, and how to build a batch script to get around them.
Filesystems store a lot of information about a file such as file name, file size, creation time, access time, modified time, created user, user and group permissions, fragments, pointer to clusters that store the file, hard/soft links, attributes… Those are called file metadata. Why do you count those metadata into file size when users do not (need to) care about them and don’t know about them? They only really care about the file content
Moreover each filesystem stores different types of metadata which take different amounts of space on disk. For example POSIX permissions are very different from NTFS permission, and there are also inode numbers in POSIX which do not exist on Windows. Even POSIX filesystems vary a lot, like ext3 with 32-bit block address, ext4 with 48-bit, Btrfs with 64-bit and ZFS with 128-bit address. So how will you count those metadata into file size?
Take another example with a 100-byte file whose metadata consumes 56 bytes on the current filesystem. We copy the file to another filesystem and now it takes 128 bytes of metadata. However the file contents are exactly the same, the number of bytes in the files are also the same. So displaying file size as 156 bytes on a system but 228 bytes on another is very confusing and counter-intuitive.
touch will create an inode, and ls -i or stat will show info about the inode:
$ touch test
$ ls -i test
28971114 test
$ stat test
File: ‘test’
Size: 0 Blocks: 0 IO Block: 4096 regular empty file
Device: fc01h/64513d Inode: 28971114 Links: 1

Notice that test uses 0 blocks. To store the data displayed, the inode uses some bytes. Those bytes are stored in the inode table. Look at the ext2 page for an example of an inode structure [WayBack].
and in case of NTFS, the size of file reported by Windows and most tools is actually the size of the main stream of the file, which we perceive as the content of the file. The file stored on NTFS partition can additionaly have some data stored in alternative data streams, and still have the reported size of 0. It’s a nice filesystem feature to know if you want to have the full picture :)
