Does anybody here know how to properly install gnuradio on ubuntu. I can't seem to install these dependencies properly. qwt (>= 5.2.0) http://sourceforge.net/projects/qwt/ pyqt (>= 4.10.0) http://www.riverbankcomputing.co.uk/software/pyqt/download wxpython (>= 2.8) http://www.wxpython.org/ python-lxml (>= 1.3.6) http://lxml.de/

hello...i would like to ask some opinion here... how i want to search/detecting the value without filtering the data? currently i'm using double hashing to search the the value... for example: i have 1000 tags with the value and will transferred to the database. however, the value considered missing when there are unable to detect the value which it is actually exist in the database.. collision could be happen within the value... so, i would like to read some opinion that possibly could help me to detect the missing value in fast way without filtering the data... thanks...

Hello Does anyone know why pdf files look a thousand times better in Foxit Reader than in Adobe Acrobat Reader (or DC)? Nothing looks smooth in Adobe, whereas everything is a piece of art in Foxit Reader. Is there a possibility to make my pdfs in Adobe look like they would look in Foxit? Because I have Adobe Acrobat DC, and I use this a lot to modify pdfs, but it's just a shame they don't look as good as in Foxit Reader. Thanks Functionella

Hi I guess this is a question about image analysis. I'm looking for an automated method of counting the number of bats in pictures, like the one below. I don't have a background in CS, so preferably I need something that doesn't require any programming. Please let me know if there exists anything that fits this purpose. Thanks in advance. FYI this is for my senior project. I'm studying how Mexican free-tailed bats synchronize their emergence. For instance, how does their echolocation intensity correlate with this group behavior. (Maybe someone will be interested in this)

I remember a few years back (before Google) when searching was simpler. Not as efficient ,for sure but the results were not skewed by advertising or geographical constraints. As an example ,I have just been searching the term "upper landing" to satisfy my curiosity that it was indeed used to indicate an area in the first floor of a building. The first pages seem to be overwhelmed with some business location in America which is called Upper Landing" and I do not have the energy to create my own filter to weed all these unnecessary results out to find what it is that I want. Is there a search engine that will not track my IP address or try to…

Hi. What did all those indicator lamps tell the operator ? The buttons, knobs, dials, selected what ?

In linguistics, a cognates are words two different languages that sound the same and have the same meaning. English "beer" and German "Bier" are cognates. Similarly, false cognates sound the same, but have vastly different meanings. English "gift" and German "Gift" are false cognates, as an English gift is something you get someone you like and the German Gift is something you give someone you want to die, namely poison. In CS, different languages have similar ideas with similar names. Floats, ints, and doubles are everywhere. I'm interested in seeing your favorite examples false cognates in programming languages. My favorite is the for loop. Python's for loop…

my computer is being hijacked,do I have to download some software to keep my computer clean as it was?That article I read provides some ways and a software named ScamSpam for me to do that,but I think there may be a better way,I hope you have a better way to help me.

I received a phone message today with a call back no. 800-549-5301. It claimed my Windows license has expired. I check no. with reverse phone directory. Many have received this call - obvious scam. Microsoft does not communicate via phone, only e-mail.

Does anybody here know how to embed visual studio code's monaco editor into electron? I thought it should be simple since vs code runs on electron but it was throwing lots of javascript errors.

So my seniors on in college recommended C++ and PHP. They said the Adobe version for C++ is good (either it was adobe or ado). So where on the net can i get both? Thank you!

I need to read a long technical document with many hyperlinks in it. If I click on a hyperlink, that text becomes visible in a different window. But what I need to do is to have these hyperlinks open on a different networked computer screen. The aim is to have several screens where the original document and several hyperlinked documents are all visible simultaneously. This seems like an obvious requirement, but we can't find any method of doing it. Any ideas anybody?

Does anyone have a halfways decent instruction manual for one of these please?

Does anybody know how to use int arrays in the inline assembly compiler for c? I tried just putting the line[index] in but that gives me a "\n" access error. #include<stdio.h> #include<conio.h> #include<stdlib.h> int i; int line[38]; int repeatedNumbers[38]; int input; int loopcount; const LAST_LINE_DATABASE = "lastline.txt"; int main(int argc, char **argv) { filed(); _getch(); exit(EXIT_SUCCESS); } int filed() { // We assume argv[1] is a filename to open FILE *file = fopen("lastline.txt", "rb"); if (file == 0) { printf("Could not open file\n"); file = fopen(LAST_LINE_DATABASE, "wb"); for (i = 0; i < 38; i = i + 1) {line[i] = 1;…

Hi, I was wondering is there any dns program that allows you to implement access control lists to only certain webpages or ban certain ip addresses so that the attacker recieves a random loopback address instead of my ipaddress?

On occasion my keyboard locks up. IBM thinkpad, Windows 7. It occurs when I am typing a message in a forum like now. Fortunately my mouse still works, so I can save the (incomplete) message and then restart the computer, freeing the keyboard. Any ideas why it is happening and is there a simpler way to free the keyboard?

Hi. I understand the malicious infections getting into computers. I do not understand why a XYZ corporation has to be in risk/ exposed to the net perils in order to conduct business and preserve sanity. All the files for the operation of a corporation, their designs, their development documents, their personnel files, sales records, data, products, payrolls and many more internal documentation of daily activity. Why do they have to be in the same computers/net with internet access ? Not saying to pull the net plug, but having NO PLUG at all ! A totally isolated internal workings. When there is need to access the web, well, another physical system of compute…

Cloud computing. Is it potentially dangerous? At the risk of sounding somewhat Luddite, why did my alarm bells instantly start ringing when I first heard about The Cloud? Being of the generation who saw the very first home computers arrive, I'm naturally used to the hard solutions, where software resides on discs and later in USB sticks. I remember actually having to get my head around the concept of owning a hard drive. Now we're not just looking at a future where our files can be stored remotely - but soon, we'll be able to boot from a remote source - and have our software titles to hand on a shared resource. Is this set to depersonalise our computing experienc…

Hi, my name is harsh, am doing my final year in computer science, and i was very much interested to a project on cloud computing. I have basic understanding of what a cloud is and i wanted to do a project on Software As A Service(SaaS) cloud computing, please help me, n tell me where do i begin from?? Any help is appreciated. Thanks in advance. -Harsh

Hey, I am generating a stream of data and using xmlhttp to send data to php backend to be saved on a new line. Each line is numbered incrementally sometimes I have instances where 6 is after 8 in my file and sometimes the line is missing entirely or has truncated data and messes up the whole program. Note that the xmlhttp requests are only sent locally and not over the internet so I am unsure why some lines would be weird like that. Has anybody here had a problem with this before? There could be maybe 100000+ requests but even one messing up is a problem. It seems to work fine in edge browser but chrome misses some requests and firefox is missing a lot of requests and…

What are adaptive learning algorithms exactly? I googled it but didn't really find anything. I read this term on an electronics forum and I really want to know what it means since I'm a noob when it comes to computer science :B

I was curious if anyone could recommend a useful resource for learning c++ and other programming languages. I am already using Lynda.com but was wondering if anyone could recommend any new resources to back up the ideas that I have already learned. Thanks

Hey, I'm a 19 year old young man about to start university. I'm going to be studying Computer Information Systems. I'm looking to get involved with Cyber Security. I'd like to know what type of laptop I'd really need. I don't need to play video games. Any answers help! I don't want to waste my money on some thing that's going to break down and give me problems. I'm not sure how powerful my processor should be. Or how much RAM I should have. Any help's great! I'm looking currently at an ASUS Zenbook Pro UX501VW. Is that a good pick? Should I downgrade? Upgrade?

I wrote an algorithm for the subset sum problem that writes a polynomial time algorithm to solve a single number set. It still takes a long time to write the algorithm though. It makes use of ranges. <script> var numbers = [1,2,-20,12,1,23,12,11,2,4,6,8,123,1298,141,211,12000,22222222,284871581091,849186386108689,9007199254740991]; var positiveEven = [],negativeEven = [], smallest; var positiveOdd = [], negativeOdd = [], largest; var sumarray = []; var ranges = [], useRanges = true, useArrays = false, useBinarySearch = false; var iterations = 0; function polynomialFunctionGenerator(){ function useRanges(){ var firstnumber = sumarray[0]; var k = 0; for(v…

I am having trouble understanding that how this complement of input variable is working in the circuit below. Please help. The Process:-- Our motive is to draw a circuit diagram with only a NOR gate of the Boolean expression :-- Step 1:-- Step 2 :-- Step 3 :-- Now from step 2 to step 3 we have to remove the inverters and complement the input variables as marked in the image. So, my question is how this complementation is working? In some places it remains the same (in below 'D' & 'A') and in some places its complements. Any help will be appreciated.
