well,
when I was working/playing in the field of compilers (long time ago), some set theory was used, however, when designing the different algorithms for the various treewalks (lots of tree walks and list processing) at least one eye was on the big O. Especially for one pass load and go compilers speed was essential (and at that time computers were not that fast) but optimizations were more related to clever programming than algorithms (e.g. the design of a set representation strongly depends on what you want to do with the set and its elements).
In my current (hobby) workingarea, software defined radio, both calculus and discrete mathematics are needed.
Processing samples - with lots of fourier transforms and some laplace transformations for the filters - is basically calculus oriented. Of course one needs to look at performance: you do not want to miss too many samples, but handling performance is also here more an engineering issue than an algorithmic issue.
Translating samples to bits and handling bits is - seen from a math position - different, viterbi decoding is a major component, as is Reed Solomon decoding, the latter using algebra (group theory). But also here, the final performance largely depends - next to selecting
decent algorithms - on clever programming and decent engineering.
But fortunately, for most of these "math" components there exists libraries (and one
can write its own),
But, the math, both the calculus and the discrete math, are basically fun to understand
and it is always a learning experience to write a library component for it.

OK - I get it - falling off to sleep whilst lustily counting sheep doesn't take calculus.
However, algebra is really a representation of how we solve problems all day long that have any sort of calculation. It's done as a background process. Now how far goes? Well - do you use all the subtleties of programming you were supposed to learn? Probably not, but you will still claim to have coded (at least in Q&A).
Sorry if you lost count of the sheep - there go your Welsh Pub bragging rights . . . unless you can exploit 'lost count' in an implied context..

Another week over? How can you tell?

I'm looking at getting a drone to be able to take aerial videos and photos. Any good recommendations will be purchased using CP currency.
Thanks.

Take a look at the DJI Mavic Mini.
It can fly for half an hour and with the weight of 249 g it's license free in most countries.

Oh, ya, I had completely forgotten about that. Not that I care much, but I guess I'll look into my local ordinances.
Thanks.

yes, Ive been eyeing off those, too, for a cycling holiday in Italy next year - now all I need is to get a job so I can think about going

If you're going on a bicycle holiday you might want to look at the big brother, DJI Mavic 2.
It has a built in obstacle avoidance system and ActiveTrack, which means you can set yourself as the target and it will follow you on your bicycle.
And amazingly enough it can do that not just behind you, but in front of you or at your side! I have one and it was quite a wtf moment when I started tracking my son from the side and it didn't fall back behind him but rather stayed at the side of him.
But all those cameras it uses for obstacle avoidance takes quite som space and weight, so it weighs 907g instead of 249g and requires registration in many most countries.

yeah, I need the functionality of the the DJI Mavic 2 in the smaller package  typical consumer, more functionality in a smaller package please
In all seriousness, I do need to look more into this, 30 minute flight time for the smaller model may be an issue, so I would have to keep 'n' batteries charged - may be too much pfaffing around on a holiday.
I see plenty of cycle-touring on YouTube though, so I'd like to give it a shot - would also mean changing my standard route to learn/test it, I doubt the prison I pass by in close proximity would like it (actually I have an app by our Civil Aviation regulation authority which marks the prison as an obvious no-fly zone)
cheers for your input Jörgen

The bigger model also have 30 minutes flight time, so no difference there.
But you can get extra batteries or the fly more combo for both.
<edit>and no fly zones are builtin to the drone. It won't fly without an overrule</edit>

Just a few days ago, my Mavic Air 2 Combo Fly More Combo arrived.
I only had time to do some small tests with it, but I am more than impressed. Highly recommended.

if you can only afford $80, Ryze Tello
if you can afford $400, DJI Mavic Mini
if you can afford $800, DJI Mavic Air 2
if you can afford more, well, I'm jealous and have no help for you...

Awesome, thanks.

I saw an ad for a webdesign company but I have my doubts about the url. The name was "web one", nothing wrong with that. The url is webone.be or am I the only one who finds it funny Probably am. It's friday...
the funniest thing about this particular signature is that by the time you realise it doesn't say anything it's to late to stop reading it

Another one for the ever-growing list of unintentionally funny domain names. Joins such luminaries as "expertsexchange", "kidsexchange", "findtherapist", and "penisland".

That is why we put the dashes in our domain name:
s-and-d-acres.farm
It makes the interpretation clear.

Until you run into the (increasingly rare, thankfully) email address field that rejects dashes!

It is far more common to run into an email address field that does not accept anything other than the old stand-bys: .com, .org, .gov, .mil and so forth.

I don't understand the name either. It seems to be a kids clothing company. It was just one of a list of "funny domain names" mentioned on an episode of QI.

I need a little humor after my latest dealing with a webdesign company. The Sr. partner decided our company website needed a new look...something 'modern'. 
Until then, all website maintenance/design was my responsibility...but I'm apparently no designer, so the partner knew of a guy who had just started a webdesign/marketing outfit. 6 months later, I'm learning how to use WordPress to edit every single hyperlink to relative. I had given him a sub-domain to build it (as he didn't have his own resources). I had expected to be handed a completed finished package for deployment, but apparently I don't know how these things work. Anyway, the plan from the beginning was to build it under a sub-domain, then simply switch the default website on the server when it was ready. This was why I wasted the effort emphasizing that all links should be relative. Yeah, it worked just fine for the demo and I'm sure the guy already got paid. I knew upfront that I would be the one maintaining it. 
This doesn't even begin to deal with the horrible design...huge background images and huge fonts. The main landing page shows a menu, one headline and a short blurb until scrolled. I suppose you could say it's a very minimalistic approach emphasizing the use of bright colors/background images, large fonts, and some weird scrolling effects and banners. But wait there's more...in order to provide consistency, new content must be created using a proprietary WordPress theme builder.
