| 02:22.43 | DocScrutinizer05 | maybe next one, yes |
| 02:22.54 | wolfspraul | nice! |
| 02:22.59 | wolfspraul | hope this works out for you |
| 02:23.07 | DocScrutinizer05 | that's why I ask ;-) |
| 02:23.38 | DocScrutinizer05 | I'm not sure I like qualcomm |
| 02:24.12 | DocScrutinizer05 | otoh who says you need to like your job, or even your employer** |
| 02:24.41 | DocScrutinizer05 | (** double deref) |
| 02:26.50 | DocScrutinizer05 | funny detail: it's so close to STE http://maps.google.de/maps?num=30&hl=de&newwindow=1&safe=off&um=1&ie=UTF-8&q=st-ericsson&fb=1&gl=de&hq=st-ericsson&hnear=0x479f57aeb5b61cd3:0xdd5daf85a98c21b7,N%C3%BCrnberg&cid=0,0,7050262622794191287&sa=X&ei=uZVSUK-aHqvZ4QSynICgAQ&ved=0CLkCEPwSMAM that I probably will meet my ex-colleagues in restaurant during lunch |
| 02:28.18 | wolfspraul | I agree that you don't need to like your job or employer, but... at the very least there does need to be cultural 'compatibility', whatever that means :-) |
| 02:28.40 | wolfspraul | if the company culture is a bunch of assholes raping the world, then you better have that same culture, and you will do well. equally for any other culture. |
| 02:28.44 | DocScrutinizer05 | actually that's another reason i'm not entirely happy with the perspective: there are realy few shops and restaurants in this whole area |
| 02:29.13 | wolfspraul | I don't know the qualcomm company culture, but culture compatibility is something you should check, for everybodys happiness... |
| 02:29.25 | wolfspraul | the few qc people I met were all very professional and serious, I liked them |
| 02:30.33 | DocScrutinizer05 | aiui my potentially new job would be more hw-centric :-D |
| 02:30.41 | wolfspraul | qc has also recently been restructuring their open source efforts |
| 02:31.02 | wolfspraul | don't know the thinking behind that though |
| 02:31.10 | DocScrutinizer05 | ooh, they have a thing like opens source efforts? |
| 02:31.38 | wolfspraul | definitely, and they are restructuring it |
| 02:32.16 | wolfspraul | I *guess* they want to separate a little better from their IP businesses so that they can protect that IP better, and at the same time can invest in anything 'open' better |
| 02:32.27 | wolfspraul | but you need to talk with them, maybe you are soon one of them :-) |
| 02:32.36 | wolfspraul | then you can explain to us! |
| 02:32.46 | DocScrutinizer05 | :-) |
| 02:35.32 | DocScrutinizer05 | thanks for the tips! |
| 02:37.07 | wolfspraul | gotta run too |
| 02:37.12 | wolfspraul | how can you be up at 4.30 btw? :-) |
| 02:37.14 | wolfspraul | k l8... |
| 02:37.32 | DocScrutinizer05 | I'm still vacant |
| 02:38.37 | DocScrutinizer05 | my pimp threated me to call yesterday, to tell me about possible meeting at qualcomm on monday, but he didn't |
| 02:38.54 | DocScrutinizer05 | threatened? |
| 02:39.12 | DocScrutinizer05 | yeah |
| 02:40.33 | DocScrutinizer05 | so otoh he "forced" me to take my remaining holiday for this year, which ends today |

| 23:47.39 | wpwrak | this is a solution for three variables: http://pastebin.ca/2204355 |
| 23:51.27 | mth | is five enough or is that just the next step up from three? |
| 23:51.45 | wpwrak | it's fun to google for this. there's a thread in a vb basic forum. proves that vb basic is for people who still have a lot to learn ;-) |
| 23:52.05 | wpwrak | what the fortran folks do looks more interesting ... http://compgroups.net/comp.lang.fortran/find-the-median-value-of-an-array/326962 |
| 23:53.00 | wpwrak | not sure yet. i very much hope it'll be enough. it has to run in a poor little microcontroller crawling at less than one MIPS |
| 23:53.44 | mth | the number of values is smaller than the range of the values? |
| 23:55.16 | wpwrak | yes, the range is much larger |
| 23:57.48 | mth | what you can do, is a limited type of quicksort |
| 23:58.43 | mth | every quicksort iteration separates the array into a segment where all elements are smaller than X, a segment where all elements are equal to X and a segment where all elements are greater than X |
| 23:58.46 | wpwrak | hmm, this seems to be the place for the algorithms: http://en.wikipedia.org/wiki/Selection_algorithm |
| 23:58.59 | wpwrak | quicksort is way too expensive |
| 23:59.29 | mth | if the "equals" segment is in the middle, you're done, otherwise continue to work on the largest remaining segment (the one that contains the middle element) |
