Another one!

 I have just found out about another programmer with schizophrenia - Terry A. Davis

In other news, my cold is slowly going away and I've had to resort to Paracetamol for a headache.

Progress, I hope

Well, the SSH Mastery Book seems to be unsuitable for my needs. Currently reading Wikipedia articles on public-key cryptography and, later on, its article on SSH.

In other news, I worked out how to get Ubuntu to launch a calculator when an otherwise unused key is pressed!

Monday...

Well, my meds didn't turn up today.

 In the morning I was reading "SSH Mastery (2e)" when I realised I needed to read "Networking for System Administrators". So I started on that.

In the afternoon I bounced around various Traveller sourcebooks, looking to get an idea of more things too read - what and when.

Productive Saturday

Today I

• Did about one and a half hours of Gardening.
• Watched the first two lectures on The Great Courses "Writing Creative Nonfiction".
• Wrote up some recent notes on my reading of "Learning Git".
  

"Learn C++ by Example" by Frances Buontempo

Currently taking part in a study group for the abovementioned book.

I was curious to see if I could write a simple filter. Using cppreference.com for information on the C++ standard libraries, I came up with this, saved into the file irb-filter.cpp:-

/*
  The most basic filter ever, copies cin to cout.

  Ian Bruntlett 5th May 2024

  To check for memory errors, do this:
  $ valgrind --tool=memcheck ./irb-filter <rose.txt

  To see cache performance, do this:
  $ valgrind --tool=cachegrind ./irb-filter <rose.txt

  See valgrind.org for more info on valgrind
 
*/

#include <iostream>
#include <string>

int main()
{
  std::string line;
 
  //std::cout << "line.capacity() = " << line.capacity() << '\n';
  //line.reserve(200); // assume lines typically 200 characters or less

  while ( std::getline(std::cin,line) )
    std::cout << line << '\n';
    //std::cout << line.capacity() << " length " << line.length() << ' ' << line << '\n';
}

I've left in some comments in case the reader want to delve a bit deeper. I've also left in some commented bits of code I used to check my understanding of what is happening when the code is being run.

I compiled the code with my makefile, which in turn ran this command:

g++ -g -Wall -Wshadow -Wconversion -std=c++23  -Wl,-Map=irb-filter.map  irb-filter.cpp   -o irb-filter

Here are the contents of rose.txt:

 The Sick Rose
By William Blake
O Rose thou art sick.
The invisible worm,
That flies in the night
In the howling storm:

Has found out thy bed
Of crimson joy:
And his dark secret love
Does thy life destroy.

git update

 OK, so it's taking a while, a lot of effort, but... I think I am getting to grips with git. Still got a long way to go but its doable.

Traveller Update

Well, we are in the third adventure, set in a world of asteroids, mining and... other things. This Traveller supplement was published 16 years ago, supporting Mongoose Traveller 1st Edition, and is still relevant. At the conclusion of the second adventure, the Travellers (aka Player Characters) were rewarded with action figures of themselves.
