Mumbo Jumbo

Programs that are full of junk or otherwise misleading. With wget, we have too much info. This example isn't specific to wget, but is a common sight. Less is more.

No human being can digest all the information in the latter. It's insane. Perhaps another flag can be used for the verbose help information, but for average daily usage, busybox wins here.

Attack of Javascript and White Space 2010's web devs!

Discourse. I hate it so much. It's as if someone who had never used a forum before thought about designing forums. They then looked at all the reasonable spacing and coherent navigation offered by php forums from the 2000's, and said: "No, I must have more white space, and a font size that is 3 times as big. I must also make it slower, by adding superfluous javascript libraries.". Thus, discourse was created: To deter people from actually using forums effectively.

IPv6 Is Badly Designed

IPv6. It was supposed to take over IPv4 over 20 years ago (yes, people were talking about IPv6 in the year 2000). In 2020, it still hasn't. Why? Because it's crap, and everyone knows it. However, the amount of corporate money invested into it, means that it may eventually get shoved down people's throats. It's not even easy to find criticisms of the technology these days. It's all being astroturfed by shills. It's like a bad movie or video game sequel. It's worse than the original. But you can't avoid it.


To begin with, IPv6 will use a 128 bit address space, as compared to 
IPv4's 32 bits. This 128 bit address is the biggest reason for IPv6. It 
is supposed to give us plenty of IP addresses to last us well into the 
future. However, 128 bits is overkill. Sixty-four should be more than 

Let's put it in terms that are easier to comprehend. We'll assume that 
there are 15 billion people on the planet. (currently, there are only 
6.1 billion, and the largest estimates for the next fifty years project 
12 billion). With 128 bits per IP address, each person could have 
2.26e28 IP addresses to themselves. If we reduce it to 64 bits, each 
person would still have 1.2 billion addresses.

What about the people who want to put IP addresses on every light pole, 
mailbox, stop light and street sign? Well, there are about 148 million 
square kilometers of land on the Earth (not including ocean). With 128 
bits, we have almost 2.3e20 addresses per square centimeter. If we 
reduce that to 64 bits, each square centimeter would still have about 
12.5 IP addresses -- more than enough.

...(Sections Omitted)

Part of IPv4's immense success was due to its 
simplicity and rigid structure. It does the job it was meant to do 
quickly and effectively. IPv6 adds all sorts of bells and whistles that 
are unneccesary and even detrimental. With all the wasted space and 
privacy issues, I'd rather have the IETF go back to the drawing board 
and come back with IPv7

Less is more. The answer isn't "add more people". The answer isn't "add more ip addresses". Things can't expand exponentially forever. There has to be limits in place. Just as humans will destroy themselves on Earth, so too will they screw up the internet.

Hidden Files

alias ls='ls -a'

Hidden files are evil. Either clean up your files and move to a directory or don't fill up directories with config crap. All ls should be ls -a. They will bite you as often as pcb makers get bitten by incorrect footprints. Its bad design. It will never go away. There's no thinking that you should've been smarter. Lies. Its the human factor. It will always, always bite you someday. Hidden files are fundamentally flawed. They will always cause trouble.

Duplication of Work

There are dozens of companies and individuals doing source code management tools. Meta-coding. The duplication of work can't ever have been this bad, and the duplication here isn't even an actual tool: it's a tool for a tool. Go ahead and search for source code / git hosting. Prepare yourself, there are way too many options. It's to the point of hyperbole.

Western cultures need to take a lesson from china. One of china's strengths, is not necessarily cutting corners, but in not doing more than is needed to complete a task. It's about efficiency. And it is possibly a sin to indulge in things that aren't necessary. Time and Life is short. Time management is critical.
