Things were still not perfect with portability even back then. I remember taking a class in OSF Motif where everybody in the class was using SPARC while I was using x86 Linux. The code was somewhat portable between platforms, but many of the arguments to the (Metroworks) Motif library functions needed their endianness swapped in order to work properly on Linux, so the code examples from the course would not run on Linux without modification.
I realize that there may be some performance improvements realized by removing cross-platform compatibility, but I do not believe that the performance gains are worth the loss in platform compatibility. If X.org does this, it will eliminate one of the core reasons for sticking with X vs. Wayland.
It should have somehow been tagged as fiction.
The zerofree command looks useful, but I don't know how portable it is. The dd method works across many platforms (such as AIX).
(unprivileged commands follow)
dd if=/dev/zero of=~/zeros bs=1M; sync; rm ~/zeros
Compressing on the fly can be slower than your network bandwidth depending on your network speed, your processor(s) speed, and the compression level, so you typically tune the compression level (because the other two variables are not so easy to change). Example backup:
(privileged commands follow)
pv < /dev/sda | pigz -9 | ssh user@remote.system dd of=compressed.sda.gz bs=1M
(Note that on slower systems the ssh encryption can also slow things down.)
Some sharp people may notice that it's not necessarily a good idea to back up a live system this way because the filesystem is changing while the system runs. It's usually just fine on an unloaded system that uses a journaling filesystem.
Defined for all values of x
Defines for some values of x
Defined for no values of x
(chose second answer) Wrong answer
Shifting (in either direction) by an amount equalling or exceeding the bitwidth of the promoted operand is an error in C99.
So according to Wikipedia: https://en.wikipedia.org/wiki/C_data_types
int signed signed int Basic signed integer type. Capable of containing at least the [−32,767, +32,767] range.[3][a]
So a minimum of 16 bits is used for int, but no maximum is specified. Thus, if my C compiler on my 64-bit architecture uses 64 bits for int, this is perfectly allowed by the specification and my answer is correct.
A better move would be to get your child out of Chicago public schools altogether.
I will cite a few examples:
Wuhan lab leak theory that was fake news until it wasn't.
Any content that questions the integrity of the 2020 election, but not content that questions the integrity of the 2016 election.
Any mention of possible alternatives to the mRNA vaccines for treating CoViD-19 -- including studies undertaken by reputable organizations.
E.g.: This now removed tweet regarding the now removed YouTube video: https://realclimatescience.com/wp-content/uploads/2022/03/Im...
YouTube (and most of social media) has lost its way. As with any other business, straying into politics and making it a core part of their decision making process is a sure way to alienate some percentage of customers/users.
I miss the good old days when businesses were focused on their business.
No idea what this did to my IQ/personality, but I somehow managed to survive (60 years so far).
