i have 2 vectors v1 , v2 equality x*v1 = v2 both v1 , v2 known time need determine x. know certainty there single x solves equation. by hand can set system of equations x. in fact don't need gaussian elimination since it's such simple setup. led me try x = v2.x / v1.x. can lead division zero. i'm writing in c++ if that's important. thanks! the asker’s own solution flawed, because fail if (v1.x + v1.y + v1.z) adds zero: x = (v2.x + v2.y + v2.z) / (v1.x + v1.y + v1.z) here correct solution problem: x = (v2.x * v1.x + v2.y * v1.y + v2.z * v1.z) / (v1.x * v1.x + v1.y * v1.y + v1.z * v1.z);

by mistake did insert in mysql rows contains duplicates, these duplicates not recognized because contain brak space eg. | id | name | -------------- | 1 | apple | | 2 | apple{b}| //the {b} show cell contains break space so when try remove duplicates not recognized duplicates... , when try remove breaks error because name unique cell what's best practice fix issue? you can use regular expressions find or delete records containing space in end: delete your_table name regexp '\s+$';

i developing android application in need show how many mails user has not replied (based on particular sender/subject) . if has done pls let me know if feasible. i haven't particularly dabbled in gmail api per googling , looking around community while, think seems feasible. think make use of labels , threads . per threads docs: the gmail api uses thread resources group email replies original message single conversation or thread. allows retrieve messages in conversation, in order, making easier have context message or refine search results. i think can tweak around it, recent message in thread, check if sent user, return true or false identifier. here's post that's retrieving reply of message , might useful. code , logic still though. hope helps somehow. luck.
