An excerpt from the best rant about whiteboard interviews posted on the internet. Ever.
"Well, maybe your maximum subsequence problem is a truly shitty interview problem. You are putting your interview candidate in a situation where their employment hinges on a trivia question. — Kadane's algorithm! They know it, or they don't. If they do, then congratulations, you just met an engineer that recently studied Kadane's algorithm.
Which any other reasonably competent programmer could do by reading Wikipedia.
And if they don't, well, that just proves how smart the interviewer is. At which point the interviewer will be sure to tell you how many people couldn't answer his trivially simple interview question.
Find a spanning tree across a graph where the edges have minimal weight. Maybe one programmer in ten thousand — and I’m being generous — has ever implemented this algorithm in production code. There are only a few highly specific vertical fields in the industry that have a use for it. Despite the fact that next to no one uses it, the question must be asked during job interviews, and you must write production-quality code without looking it up, because surely you know Kruskal’s algorithm; it’s trivial.
Question: why are manhole covers round? Answer: they’re not just round, if you live in London; they're triangular and rectangular and a bunch of other shapes. Why is your interview question broken? Why did you just crib an interview question without researching whether its internal assumption was correct? Do you think that “round manhole covers are easier to roll" is a good answer? Have you ever tried to roll an iron coin that weighs up to 300 pounds? Did you survive? Do you think that “manhole covers are circular so that they don’t fall into manholes” is a good answer? Do you know what a curve of constant width is? Do you know what a Reuleaux triangle is? Have you ever even been to London?
If the purpose of interviewing was to play stump the candidate, I’d just ask you questions from my area of specialization. “What are the windowing conditions which, during the lapping operation on a modified discrete cosine transform, guarantee that the resynthesis achieves perfect reconstruction?” The answer of course is the Princen-Bradley condition! Everyone knows that’s when your windowing function satisfies the conditions h(k)2+h(k+N)2=1 (the lapping regions of the window, squared, should sum to one) and h(k)=h(2N−1−k) (the window should be symmetric). That’s fundamental computer science. So obvious, even a child should know the answer to that one. It’s trivial. You embarrass your entire extended family with your galactic stupidity, which is so vast that its value can only be stored in a double, because a float has insufficient range:"

HP sucks because:
shitty hinges,
shitty build quality,
shitty USB ports,
shitty customer service,
shitty website6 -
Let me just get right down to it.
FUCK YOU Hewlett-fucking-Packard FOR YOUR SHITTY LAPTOPS! Don't you even keep your customer's needs in mind when you design these things? Besides all the bloatware you stuff into the Windows you ship it with, at least make the quality of your shit better. These flimsy screens and loose hinges, I've had to get that shit replaced multiple times in just the past year.
Want to upgrade to an SSD or plug in more RAM? Guess what! I've to tear the whole thing apart! Keyboard, palm rest, all if it! What even happened to just popping a cover at the bottom to swap out the hard drive!? I have to fucking congratulate you, you fucking cunts, for making an easy process as difficult as it can fuckin possibly get. You guys deserve an award for this, preferably presented to you, shoved up your asses.10 -

routers need to go on the technology list of shitty tech
qberry1 [3:04 PM]
working on a rant
[3:04]
may post it on devrant
[3:04]
Here is a list of technologies that I hate.
Printers:
Can we not make a printer that isn't a POS? We've been making them for years and they still suck.
Bluetooth:
It is supposed to be convenient, but it never pairs when you want it to. It is always when you are driving and dont have time to mess with it that it doesn't work.
Bluetooth Printers:
See above for details.
Routers:
Can we not make a router that lasts longer than a year?

God Damn Laptop Hinges
[3:05]
On anything but MacBooks
qberry1 [3:05 PM]
yeah
[3:08]
satellite radio
[3:08]
what a load of shit
lquessenberry [3:09 PM]
Yeah fucking 48 bit napster mp3s sound better than Satellite radio
qberry1 [3:09 PM]
if i wanted to hear music that sounds like ballsack i'll go download it from napster
lquessenberry [3:09 PM]
^^^^
[3:09]
Boom
qberry1 [3:09 PM]
