I’m trying to just literally never argue with people

Posted on by

I’m reading this great interview with Marc Andreessen in which he says:

I’ve really been trying hard to spend less time actually arguing with anybody. Because people really don’t want to change their mind. And so I’m trying to just literally never argue with people.

…I thought that was worth making a note of. I think I’m going to take that on board.

Most bugs are in your error handling code

Posted on by

While reading What tools made you better programmer I came across a link to Error Handling in a Correctness-Critical Rust Project which included these two tidbits:

almost all (92%) of the catastrophic system failures are the result of incorrect handling of non-fatal errors explicitly signaled in software.

in 58% of the catastrophic failures, the underlying faults could easily have been detected through simple testing of error handling code.

Konsole column width

Posted on by

So after having read this I was trying to configure Konsole by editing my config files under

~/.local/share/konsole

and I couldn’t get my column width config to apply.

The problem was that I was configuring column width with the TerminalCols setting, but the correct setting is actually TerminalColumns, which was difficult to figure out! Not sure how I managed to get that wrong in the first place, but it’s fixed now.

My new Konsole dimension settings are:

TerminalColumns=100
TerminalRows=42

salt stack file_tree.py

Posted on by

So in my version of salt, v2017.7.4 (Nitrogen), I was getting this error when I tried to use the file_tree ext_pillar:

Failed to load ext_pillar file_tree: must be str, not bytes

So I monkey patched my version of /usr/lib/python3/dist-packages/salt/pillar/file_tree.py, changing the file from binary to text:

            contents = ''
            try:
                # 2020-05-15 jj5 - changed 'rb' to 'r', will only work with text files...
                with salt.utils.fopen(file_path, 'r') as fhr:
                    buf = fhr.read(__opts__['file_buffer_size'])
                    while buf:
                        contents += buf
                        buf = fhr.read(__opts__['file_buffer_size'])
                    if contents.endswith('\n') \
                            and _check_newline(prefix,
                                               file_name,
                                               keep_newline):
                        contents = contents[:-1]

HTML forms

Found a cool series of articles: How to Build HTML Forms Right. Only the first two of five articles have been published so far, but I’m looking forward to the next three. The articles are about how to do forms right in HTML 5.

The articles are rich with links, click through for heaps of info. Some things that I found:
