Well, I take several approaches, often multiple ones:
- Determine test fixture -- what do I need to set up to actually debug / test? How do I isolate the test fixture? How can it be automated so I'm not clicking through the UI?
- Write the test first. I actually do this very rarely because I find it hard to express the test results ahead of time. It's only when I write the actual code that I think, ok, this needs to be tested, that needs to be tested. Also, when dealing with new technologies, I often don't know what the format of the data is until I get the hardware or API working -- what does the card scanner actually give me, what does the JSON actually look like?
- Step through the code. I do this almost all the time to make sure that I'm understanding correctly the tech with which I'm interfacing.
- Write the test after writing the code. For certain things, I definitely do this. Once the baseline code is working, I can then throw different scenarios at it. Useful scenarios that represent anticipated use cases, not just mindless contract testing or the like.
- Debug the tests.
- Try out the code via the UI. Funny thing is, that often reveals things I didn't consider.
- Put the app in front of someone else. Not so funny is seeing how other people go about using the app, and the bugs that are revealed in that process. Not just algorithmic bugs, but also UX bugs -- if the user experience sucks, I consider that a bug.
- Put the app in front of select customers. Very revealing and is the best way to discover that the spec itself is buggy.
So debugging is not just about code. It's about the user experience, whether the spec accurately captured the user's needs, and understanding how stuff is used in the wild.

No need to debug if you get it right the first time! Of course, this rarely happens!

I used to check in insect repellent with my code in TFS. I had to stop because of that awful code smell.

I test as I go. I'd rather debug 10-50 lines than get 100's of lines in to find I must have been smoking the wacky taccy with code that had no hope of ever working.
When people bring me code they want help debugging, I usually gut the code to something smaller and gives proof of concept instead of dealing with all the bells and whistles they coded before finding if the core code was going to work in the first place.

This reads like it was completely computer generated. Then again, I've known some women I would certainly describe as "glacial."

In Australia 'ice' is colloquially used to describe Meth.
Might be relevant gor Trump.

But, did you ascribe the adjective, "glacial," only after you were unable to melt them, and there was no run-off ?

Does that refer to their mood or speed of thought? Or perhaps what seems to be the case here, both.

In a rational world, the author of this piece of drivel would be tarred, feathered, and run out of her university on a rail.
In our world, she'll probably be put on the short track to tenure.

Well that's one 'possibility space', certainly but let's not get too caught up in paradigmatic analysis too hastily lest we collapse the dialectic. It is essential that we lucubrate on perambulation before we envisage accelerated motion.

For years I was saying, that we value to much the research universities make...so we give too much money to run them and we end up with such idiotic results...

This sort of article just show how rich we have all become - we can afford to waste tens of thousands of dollars on people who couldn't express a coherent thought to save their lives.

The problem is that university tenure now depends so much on publishing rather than genuine results or teaching ability that lecturers and professors simply do not have time to reflect on their latest brilliants ideas. It has to be got down on paper and into a journal asap. It's quantity not quality that vice-chancellors and department heads will be totting up at the end of each academic year.

Tell me about that...
One of our customers, became an university (from collage) not too lately... It was some horrible place even before (they run for the research money to get the 'university' label), but now it is just catastrophic...

Another in our occasional series of new albums that I didn't think I'd enjoy but are getting more than a cursory second listening: Limitless by Tonight Alive
Sample track: To Be Free[^]
This is the second album by an Ozzie band which has got some criticism from the native rock press for the abandonment of punk elements in the first and for being too polished but you can't have everything. Bit of a genre defying outing with all kinds of influences (this track even suggests a bit of Little Big Town style country in places) but with a familiar pop/rock foundation (sometimes bordering on rock cliche but rescued by outstanding vocals).
Anyway, enjoy ... or not. There won't be a test!

Why, what does this have to do with rock?
It's just a nice and catchy pop song

That's the question they're asking. The band's initial reputation was built on a much harder, less pure, punk.
