I don't know what is going on.

It takes ~.8 seconds with a 660ti as it was written in that post, which is about double what @Ciccioo 's solution takes. By using a sieve to calculate primes on the CPU then sending the rest of the problem to the GPU takes it down to about .4 seconds. It's not really a great problem for comparing parallel to serial because the serial algorithm is just so much more efficient than the parallel version because it takes advantage of previously calculated values.

A bit overkill for the problem but cuda ftw

Thanks a lot but you didn't have to since it was my fault for being an idiot . Sorry about that will keep in mind for future submission and thanks again.

I deleted the incorrect submissions since it was a matter of formatting. All problem results end with a line break, keep that in mind from now on.
 
Good job, I encourage you to keep going!

foreach (int val in scoresArray) you are using int there, but the scoresArray is a double array

OHHH lol I need to press enter again for the second line as well.....FML all those "incorrect"s lol
Sorry
 
COMPLETE LACK OF ABILITY TO FOLLOW DIRECTIONS!!! lol my bad
 
 
Code: VB.net
 
Code: C#

i think that they both should work, but i usually go with manually pressing enter, so you should be safe using that method

Woah-woah-woah. A driver? Don't you think that is way too harsh?

No, it's just a little bit more complicated. Things aren't as streamlined.

mmm they look right to me
the number of primes is correct, the last few primes and the first few primes are correct too, so you should be good
be careful to put a line break after each of the two line when you submit your solution

Yes it is JSON and here's a quick Python script for logging in and calling the new API, it doesn't do any error checking and I don't know if the "auth_key" ever changes.

import urllib, urllib.request, http.cookiejar, time, jsonuser = '<your username>'password = '<your password>'loginURL = 'https://linustechtips.com/main/index.php?app=core&module=global&section=login&do=process'apiURL = 'http://linustechtips.com/main/page/api.php'cj = http.cookiejar.MozillaCookieJar()opener = urllib.request.build_opener(urllib.request.HTTPCookieProcessor(cj))opener.addheaders = [('User-agent', 'Opera/9.80 (Windows NT 6.1; WOW64; U; de) Presto/2.10.289 Version/12.01')]login_data = urllib.parse.urlencode({'ips_username' : user, 'ips_password' : password, 'auth_key' : '880ea6a14ea49e853634fbdc5015a024', 'referer' : 'http://linustechtips.com/main/', 'rememberMe' : '1'})resp = opener.open(loginURL,login_data.encode('utf-8'))while True: resp = opener.open(apiURL) text = resp.read().decode() resp.close() js = json.loads(text) print('User name: ' + js['display_name']) print('New notes: ' + js['new_notifications']) print('New pms: ' + js['new_pms']) time.sleep(5)

Hmm I started messing with HTML and JS simetime in 7th grade (~13 years old) and thought at the time, "oh yeah... I know programming" lol. Later I thought "I want to make something that isn't a webpage or ran in a browser" so I went to youtube in 9th grade to try to learn C/C++. I failed miserably at the time and looked for an alternative that I could grasp but was still able to achieve what I wanted. Found something called RealBasic. Dabbled in that for a week, then I found VB. At the time I was very ignorant about anything programming and while looking up tutorials for VB I mistakenly and unknowingly learned VB.net (VB6 vs VB.net, I didn't know at the time since the search term I used was simply VB with no specifics and thought .NET was just part of an address). Throughout highschool I learned and did more vb.net. After highschool I went into networking at Pennsylvania Institute of Technology and we had a JS class that thaught me much more about JS (before I just mostly modified code). Learning to write JS gave me a grasp on the syntax schemes which varied among languages, with that I thought I can tackle C/C++ again but I didn't take the plunge until right before I started my programming class at Devry University (DO NOT go there, they are rip off artists and a horrible school which I later dropped out of). Before classes started I somewhere somehow got the motivation to look into tutorials and in about a week I learned most of the basics etc (no classes or interfaces etc, mostly creating functions, some math and output). I did very well in the C++ class imo and provided help to anyone in the class that was struggling or just needed the help via skype (got in trouble because on some assignments the code of the people I helped was similar to mine, and I was asked to stop helping). After I dropped out a friend of mine was still in school and was learning java and he asked for some help. I knew nothing of java and he said (probably jokingly) "learn it" and I did lol. Ofc not java as a whole, I learned the basics etc and just brought over what I knew from VB and C++. While helping him I usually write everything in VB and then converted the logic over to Java afterwards (when I can), it was an inefficent way but at the time it was hard for me to just jump right into java. Even today I write most things in VB because I am most comfortable in it and it does what I need. The only problem my friend had was my VB source and to make things easier I rewrote in C# sometimes. I want to dabble into x86 one day and ARM even though I hate it (for no legitimate reason lol). I am now 23 and while I like programming I cant say I am a very fast learner of it nor good at it but I do it as a hobby and I learn more by finding problems and googling on how to fix them or wanting to implement a feature I don't know how to yet.

PS: I forgot to mention I learned R to help a friend in some bio-chem stuff. Its a useless language imo and also dabbled in D for a bit out of curiosity (will probably be my main language in the not so near future).

Here is one in VB I made today for a friend and remembered this thread, Don't know if VB is valid but here it is:

He wanted me to teach him how to flip an image horizontally because his camera captures it flipped the wrong way, so instead I made this.
