Hi bakunin...

Oh boy, I reckon I am gonna love this thread. ;oD
And I thought I was alone. Now you have set me off. I agree with everything you have written.
(Apologies for any typos.)

I have been into electronics all my life until retirement, getting my degree as a student apprentice from Marconi Radar Systems from 1968 - 76.
Went through life changes to eventually become a major shareholder in a company that designed, installed, repaired and maintained medium to high power RF equipment, transmitters, receivers and associated gear from around 1 Watt to several KiloWatts, 1980 - 2015, when I retired.

Oh those days of valve/tubes when you could see the components, and fondle them with such affection. Repairs and maintenance were difficult but very easy.
Then came the transistorised stuff and the units sizes collapsed considerably. You could still feel those components but their sizes had also collapsed. Repairs and maintenance were also difficult and easy.

Now we hit the DIP 7400 and 4000 series ICs and still that air of component size but the units are an order of magnitude more complex and require a database as to what these DIPs do, so I was forced to understand pure logic and be able to design stuff around them. Repairs and maintenance were much the same as the transistorised stuff.

Oh boy, we now hit surface mount microprocessors and peripheral ICs but still with standard type passive components. These things are an order of magnitude more complex too. Oh dear, we can't reliably replace faulty chips manually the old way, we need a proper workstation. So several grand UK pounds later we are now able to do repairs and maintenance.

Surface mount. UGH! This has evolved into anything but repairable, at first you could at least see the passives but these reduced in size by orders of 2 magnitude without degrading reliability until they just looked like tiny pieces for grit, forget about repairs and maintenance, just pull the board and chuck.

And finally everything in the super-surface mount IC itself. Scrap if it has failed and get a new unit complete, the IC[s] can't be removed by our now ancient workstation and there is no means of tracing a fault inside a black slab containing near unlimited components.

And everything is for the better.

There is much more but I want to read others rants too... ;oD

RANT(1) 						      General Commands Manual							   RANT(1)

NAME
rant - A flexible and portable build tool. SYNOPSIS
rant [OPTION] ... [TARGET] ... DESCRIPTION
Striking features * Defining custom tasks. * Automated packaging, testing and RDoc generation for Ruby applications and libraries. * Creation of a monolithic script tailored to the needs of a specific project which can be used instead of an Rant installation - users don't need to install Rant. [See man rant-import] * Creating gzipped tar and zip archives -- without installing additional software. * Optional recognition of file changes based on MD5 checksums instead of file modification times. * Dependency checking for C/C++ source files (integrated makedepend replacement). * Primitive support for compiling C# sources with csc, cscc and mcs. Startup On startup, rant will look for a file called Rantfile , rantfile or root.rant which contains the build specification (which in fact is valid Ruby code). After reading the Rantfile(s), rant will execute the following tasks: If at least one target was given on the commandline: rant will execute all tasks necessary to build all targets given on the commandline. else: rant tries to build the target called "default". If no task with this name exists, rant invokes the first defined task. If you want to know which task(s) will be invoked when no target is given on the commandline, run rant with the -T option. Example: $ rant -T rant # => test rant package # Create packages for distribution. rant doc # Generate documentation. rant publish-docs # Publish html docs on make.rubyfore.org. # Note: scp will prompt for rubyforge password. rant test # Run basic tests. The first line always shows the target that will be built if no target argument is given. In this case, it would be the test target. OPTIONS
--help -h Print a help message and exit. --version -V Print version of Rant and exit. --verbose -v Print more messages to stderr. --quiet -q Don't print commands. --err-commands Print failed commands and their exit status. --directory DIRECTORY -C DIRECTORY Run rant in DIRECTORY. --cd-parent -c With this option, Rant starts to search for an Rantfile in the current working directory as usual, but if it doesn't find one, it changes to the parent directory and looks there for an Rantfile. This is repeated until an Rantfile is found or the working directory is the root directory of the filesystem. --look-up -u Look in parent directories for root Rantfile. --rantfile RANTFILE -f RANTFILE Process RANTFILE instead of standard rantfiles. Multiple files may be specified by repeating this option. --force-run TARGET -a TARGET Force rebuild of TARGET and all dependencies. --dry-run -n Print the names of the tasks that would be executed instead of actually executing task actions. --tasks -T Show a list of all described tasks and exit.
