Implying non-sports cars are like sports cars in marketing

Not sure precisely how to word it, but the title is my attempt.

In short, it bugs me when these commercials come on that do something like show sports and/or racing cars then show their suv/crossover/blandsedan/etc doing some showy crap like sliding across a wet runway, blasting through a desert, colored smoke machines, fighter jets, or whatever other nonsense they think looks cool. It’s usually with 30 camera cuts and what will only be used to go to Target take kids to soccer practice.

I get it…if it makes money for the company, it worked. Maybe I’m a curmudgeon – most commercials bug me – but this type of stuff really does. Here’s one I just saw that inspired this post.

Does this bother anyone else? Do you have any examples you’d post?

My brother in laws 1000+ hp Shelby. I’m too scared to drive it.

This car is insane. I’ve been staying with my sister and bro in law for a few weeks so I’ve had the pleasure of going around town with him. Last night he asked if I wanted to drive it, fuck that I know my limits.

I’m trying to find a video of him MURDERING a GTR and the guy literally ended up selling it and buying a Shelby lol.

N54 tuned reliability

In recent weeks I’ve been playing with the idea of picking up a 335 or 135 and getting a tune + downpipe on a n54 as they seem to make some pretty incredible numbers.

That being said, how reliable are these cars? I’ve never owned a car outside of trucks which have been pretty good to me. Is something like 5k+ a year in maintence a real thing?

Any input is great. Input on the 3.0 Tfsi audi is also appreciated as I also consider them

Ideas for projects using Python, R or SQL

Hi! I am a 3rd year Statistics Major, applying for Co-op placements for the coming summer. I’m looking into putting some projects onto my resume to both look good to employers and to actually become more familiar with R and SQL (I’m pretty comfortable with python, but I wouldn’t be against a project that used a combination of python and another language). What kind of projects using R and/or SQL would look good on a resume for statistics/data science jobs? I have very little experience with R and SQL, but I am very good at googling, so any beginner/intermediate project ideas would be perfect! I am also currently learning R and SQL online to have working knowledge of them by the time I get to interviews. Any help/ideas would be greatly appreciated!

Request: is there an elegant solution to this combinatorics problem? Details in comments

This is a variation on the standard combinations problem; my twist is that each element has a variable number of types.

I need to compute a few things about parts kits, including 1) the total number of variations for a given kit size, 2) given an alphabetical (or other) sort order, how to compute the index of each variation.

I also would like 3) to determine whether all variations for each part type have been used, which I could do using the index from #2 above. I would settle for an answer to just the first issue.

Example We have have certain a number of part categories, n. Each kit has k parts. Each part type has c_i_ variations. If there were no variations on part types, this would be a standard combination of n! / k!(n-k)!. Sample follows:

Index Part Category Variation Name Count C_i_
1 Battery Normal,rechargable 2
2 Chassis Normal, sturdy 2
3 Cowling Black, green, red, yellow, white 5
4 Motor m1, m2, m3 3
5 Screw Flat, Philips 2
6 Tubing Durable, hi temp, medical, textured 4

For this example, if n=6; if we assume each kit has k=2 parts, then there are 15 = n!/k!(n-k)! “classical” combinations, but 131 combinations taking into account the varieties of parts, as illustrated in the table at the bottom. I need to find an elegant way to compute the value 131.

Note that each kit only has 1 of each part category, so, for example, we can’t have 2 batteries in a kit.

The 1st issue is that computing the answer of 131 variations is not elegant and also somewhat computationally intensive, it seems like there should be an easy solution; I have tried, but but I can’t factor anything out. As an example of the 2nd part of my problem, I wish to easily determine, for example, if we have used every possible cowling color, or every possible tubing type.

3) Index example: using the example below, and the alphabetical sort order,

  • 1 = index for normal battery/normal chassis
  • 2 = index for rechargeable battery /normal chassis
  • 3 =index for normal battery/sturdy chassis
  • 131 = index for Phillips screw/medical tubing
  • etc.

As you can see in the table below, there are 15 combinations when you only consider the part type; on the right I have listed the actual count for each “sub-combination”:

Part 1 Part 2 Formal Count for this combination Actual Count
Battery Chassis c1 x c2 2 x 2
Battery Cowling c1 x c3 2 x 5
Battery Motor c1 x c4 2 x 3
Battery Screw c1 x c5 2 x 2
Battery Tubing c1 x c6 2 x 4
Chassis Cowling c2 x c3 2 x 5
Chassis Motor c2 x c4 2 x 3
Chassis Screw c2 x c5 2 x 2
Chassis Tubing c2 x c6 2 x 4
Cowling Motor c3 x c4 5 x 3
Cowling Screw c3 x c5 5 x 2
Cowling Tubing c3 x c6 5 x 4
Motor Screw c4 x c5 3 x 2
Motor Tubing c4 x c6 3 x 4
Screw Tubing c5 x c6 2 x 4
Grand total 131

The problem with this is it looks like I need to sum 15 products; that isn’t too bad when n=6, but this is just an example, and in the real world, n is much bigger. I hope there is a more elegant solution.

BMW or Mercedes?

Over the past year+ I have become much more financially sound, with a new job that has enabled me to afford a nice car for the first time in my life.

I currently drive a ‘99 Camry that is really up there in miles and last year needed a new exhaust. I am preparing for my next car as this one simply won’t be something I want to invest anymore money into.

I want to buy a luxury car when it’s time and I have been researching a lot, which has lead me to discover I know nothing about cars.

Which is generally a better buy, BMW or Mercedes? Or is it just down to preference and specific model? I know neither one is anywhere close to the most economical and both will cost more to repair when needed, but I am tired of driving beat up cars for the past 20 years and want to finally have a really nice car.

Any advice is much appreciated. I would be looking for slightly used (probably a former lease now being sold) and have a budget of about $45,000.

How rigorous and extensive is the present mathematical research on voting theory?

I’ve started looking into doing some research into voting systems (mostly expanding Arrow’s Theorem to approval voting systems and looking into which systems optimize certain utility functions).

Looking at the literature, a lot of it seems to be less actual math than I would hope, and a lot of pieces to be sort of missing from Google Scholar. I get this feeling that I’m looking in the wrong place for past research (I don’t usually do math research). Does anyone here have experience in this domain, and would be able to point in in a helpful direction?
