  • Is acoustic fingerprinting too broad for one audio file only?

    - by IBG
    We were looking for some topics related to audio analysis and found acoustic fingerprinting. As it is, it seems like the most famous application for it is for identification of music. Enter our manager, who requested us to research and possible find an algorithm or existing code that we can use for this very simple approach (like it's easy, source codes don't show up like mushrooms): Always-on app for listening Compare the audio patterns to a single audio file (assume sound is a simple beep) If beep is detected, send notification to server With a flow this simple, do you think acoustic fingerprinting is a broad approach to use? Should we stop and take another approach? Where to best start? We haven't started anything yet (on the development side) on this regard, so I want to get other opinion if this is pursuit is worth it or moot.

  • SEO issue - External links rel="nofollow" or NOT!

    - by Mary Melody
    Previously I created a website for promo codes and coupons. That have hundreds of external links to the Retailer's websites and I used rel="nofollow" tag. But my site SEO rank was very very... bad especially on Google. So then I removed the rel="nofollow" tag, but no improvement. The only difference between this site and my other sites is "External links". My other sites have good ranking on Google. Now I'm creating a site for reviews. So this is also similar situation for me. I just want to know about how does SEO react with external links? and then what possibly happened in my case?

  • How to explain bad software to non-technical people?

    - by mtutty
    In discussing software development with non-technical people (customers, business owners, project sponsors, etc.), I often resort to analogies and metaphors. It's relatively easy and effective to use a "house" or other metaphor for describing the size and complexity of new development. However, we often inherit someone else's code or data, and this approach doesn't seem to hold up as well when trying to explain why we're gutting something that already seems to work. Of course we can point to cycle time and cost to be saved in the future but this generally means nothing to business folks. I know doctors can say "just take this pill," but I'm not sure that software devs have the same authority. Ideas? EDIT: Let me add a bit to the discussion. The specific project I'm talking about has customers that don't realize (or care) about specific aspects of the system we're retiring (i.e., they think it was just fine): The system would save a NEW RECORD every time someone updated a field The system contained tables for reference data. These tables had new records added every day, even though they were duplicates of previous records. And there was no way to tie the reference data used for a particular case at the time it was closed. This is like 99% of the data in the old system. The field NAMES also have spaces, apostrophes and other inappropriate characters in them, making everything harder to work with. In addition to the incredible amount of duplicate data, they have around 1000 XLS files with data they want added to the system. Previously, they would do a spreadsheet for each case in the database, IN ADDITION TO what they typed into the database. Getting rid of this old, unneeded information and piping in the XLS data comprises about 80% of the total project effort, and was not something we could accurately predict. I'm trying to find a concrete way to describe how bad this thing was, mostly so that the customer will understand why the migration process has been so time-consuming. The actual coding was done pretty quickly and the new system works fine, but without the old data they won't be happy. Sorry to get into the weeds, but most of the answers I've seen so far are pretty basic scope/schedule/cost things. I've been doing this for 15 years, so this really is more of a reflective, philosophical question - but without some of the details it can be difficult to really appreciate the awful beauty of this problem.

    What implementation problems has the industry claimed to have solved many times, but are still soaking up all of your time? Examples: Cross platform GUI - mobile devices have blown this issue wide open. OO to RDBMS mapping - how do I map this attribute to that field in that database using that framework. You get the idea. Interface definitions - ..., CORBA, COM, EJB, WSDL, ..., etc Can you think of any others?

  • Do I need to go to a big-name university?

    - by itaiferber
    As a soon-to-be graduating high school senior in the U.S., I'm going to be facing a tough decision in a few months: which college should I go to? Will it be worth it to go to Cornell or Stanford or Carnegie Mellon (assuming I get in, of course) to get a big-name computer science degree, internships, and connections with professors, while taking on massive debt; or am I better off going to SUNY Binghamton (probably the best state school in New York) and still get a pretty decent education while saving myself from over a hundred-thousand dollars worth of debt? Yes, I know questions like this has been asked before (namely here and here), but please bear with me because I haven't found an answer that fits my particular situation. I've read the two linked questions above in depth, but they haven't answered what I want to know: Yes, I understand that going to a big-name college can potentially get me connected with some wonderful professors and leaders in the field, but on average, how does that translate financially? I mean, will good connections pay off so well that I'd be easily getting rid of over a hundred-thousand dollars of debt? And how does the fact that I can get a fifth-years master's degree at Carnegie Mellon play into the equation? Will the higher degree right off the bat help me get a better-paying job just out of college, or will the extra year only put me further into debt? Not having to go to graduate school to get a comparable degree will, of course, be a great financial relief, but will getting it so early give it any greater worth? And if I go to SUNY Binghamton, which is far lesser-known than what I've considered (although if there are any alumni out there who want to share their experience, I would greatly appreciate it), would I be closing off doors that would potentially offset my short-term economic gain with long-term benefits? Essentially, is the short-term benefit overweighed by a potential long-term loss? The answers to these questions all tie in to my final college decision (again, permitting I make it to these schools), so I hope that asking the skilled and knowledgeable people of the field will help me make the right choice (if there is such a thing). Also, please note: I'm in a rather peculiar situation where I can't pay for college without taking out a bunch of loans, but will be getting little to no financial aid (likely federal or otherwise). I don't want to elaborate on this too much (so take it at face value), but this is mainly the reason I'm asking the question. Thanks a lot! It means a lot to me.

  • Adding a small slide when player releases left/right key

    - by Dave
    the aim is for the player object to slow down and stop instead of just stopping dead. The following codes works ok when the player is not jumping, but gets stuck in an object if the player is in the air when they do it. Left Key released event: if hsp = 0 exit; hspeed = -3; friction = 0.20; if obj_Player.hspeed = 0 { hspeed = 0; } Right key released event: if hsp = 0 exit; hspeed = +3; friction = 0.20; if obj_Player.hspeed = 0 { hspeed = 0; } and here's the horizontal collision code for interest: if (place_meeting(x+hsp,y,obj_bound)) { while(!place_meeting(x+sign(hsp),y,obj_bound)) { x += sign(hsp); } hsp = 0; } x += hsp; Any help would be much appreciated. Thanks.

  • Why is not there a python compiler to native machine's code?

    - by user2986898
    As I understand, the cause of the speed difference between compiled languages and python is, that the first compiles code all way to the native machine's code, whereas python compiles to python bytecode, to be interpreted by the PVM. I see that this way python codes can be used on multiple operation system (at least in most cases), however I do not understand, why is not there an additional (and optional) compiler for python, which compiles the same way as traditional compilers. This would leave to the programmer to chose, which is more important to them; multiplatform executability or performance on native machine. In general; why are not there any languages which could be behave both as compiled and interpreted?

  • Newbie in ASP.Net

    - by dnvThai
    I am learning ASP.Net and I am confusing between ASP.Net WebPages, ASP.Net WebForms and ASP.Net MVC. I have read a lot of articles and known the simple difference of their functions, but I don't know the differences of their code. E.g: When I look at int* p = new int(); ... I know that it's C++ style. and Dim A as String it have to be Visual Basic. [?1] I'm not able to detect like that in ASP.Net. How do they different in codes? I use Visual Studio 2010 Express Edition.I like to use C# (I also was learned VisualBasic in shool, but I don't like him). When I create a new project, there're too many types of project, then, I don't know which I should choose (I just want to make a simple site). [?2] What are they used to? Thanks

  • Career Shifters: How to compete with IT/ComSci graduates

    - by CareerShifter
    I am wondering what are the chances of a career shifter (mid 20's), who have maybe 3-6 months programming experience vs. younger fresh IT/Com Sci graduates. You see, even though I really love programming (Java/J2EE), but nobody gives me a feedback when I apply online. maybe because they preferred IT/ComSci graduates vs a career shifter like me.. So can you advice on how to improve my chance on being hired. How can i get a real-job programming experince if nobody is hiring me. I can make my own projects (working e-commerce site blah blah) but it is still different from the real job. And my codes are working but it still needs a lot of improvement and no one can tell me how to improve it because no one sees it (because I'm doing it alone?). Do you know any open source websites (java/j2ee/jee) / online home-based jobs who accepts java/j2ee/jee trainees.. Thank you very much

  • How do I transition from physics and math to programming?

    - by inovaovao
    I'm a physics PhD with little actual programming experience. I've always liked programming and played around with BASIC, Pascal as a teen, but the extent of my experience writing complex programs comes from an introductory course in computer science. Now I've decided that I'm more interested in programming than in physics and started to learn Java. Coming from a physics or math-heavy background, what would be the best strategy to maximize my value in the field?
