  • Database for Large number of 1kB data chunks (MySQL?)

    - by The Unknown
    I have a very large dataset, each item in the dataset being roughly 1kB in size. The data needs to be queried rapidly by many applications distributed over a network. The dataset has more than a million items (so 500 million+ 1kB data chunks). What would be the best method to storing this dataset (need to allow adding more items, and reading them rapidly, but never modifying already added data)? Would using a MySQL DB using the binary blob format be appropriate? Or should each of these be stored as files on a file system? edit: the number is 1 million items now, but needs to be able to scale to well over 500 million items easily.

  • Random numbers from binomial distribution

    - by Sarah
    I need to generate quickly lots of random numbers from binomial distributions for dramatically different trial sizes (most, however, will be small). I was hoping not to have to code an algorithm by hand (see, e.g., this related discussion from November), because I'm a novice programmer and don't like reinventing wheels. It appears Boost does not supply a generator for binomially distributed variates, but TR1 and GSL do. Is there a good reason to choose one over the other, or is it better that I write something customized to my situation? I don't know if this makes sense, but I'll alternate between generating numbers from uniform distributions and binomial distributions throughout the program, and I'd like for them to share the same seed and to minimize overhead. I'd love some advice or examples for what I should be considering.

  • Audio Streaming API's: Wifi vs what?

    - by Moshe
    I've noticed certain radio apps, that some stations required wifi and others did not. What were those other stations possibly using? Are there other methods of streaming audio on iOS? Apparently, I was not clear in my question before. I'm asking in terms of API's. Is there an API to interact directly with say, FM radio, on iOS? Is wifi the only way of streaming audio?

  • Linking and Redirecting between multiple applications running under a single system folder

    - by Gurunandan
    I am running multiple applications with a single Codeigniter system/ folder using the recommended way on the Codeigniter wiki. Each application runs fine and I can link between apps using absolute URLs. Is there some way I can use or extend the URL helper class (functions like anchor(), redirect()... etc.) to generate links to controllers across applications. I would like to avoid absolute URLs Thanks!

  • Global variables in hadoop.

    - by Deepak Konidena
    Hi, My program follows a iterative map/reduce approach. And it needs to stop if certain conditions are met. Is there anyway i can set a global variable that can be distributed across all map/reduce tasks and check if the global variable reaches the condition for completion. Something like this. While(Condition != true){ Configuration conf = getConf(); Job job = new Job(conf, "Dijkstra Graph Search"); job.setJarByClass(GraphSearch.class); job.setMapperClass(DijkstraMap.class); job.setReducerClass(DijkstraReduce.class); job.setOutputKeyClass(IntWritable.class); job.setOutputValueClass(Text.class); } Where condition is a global variable that is modified during/after each map/reduce execution.

    - by Brad Hein
    I've written an Android app wich various abstract classes that perform useful functions. These functions could be leveraged in other apps. I want to share a class module with another programmer, but I don't want to share the source code. I would like to share a .class file but I'm not sure how to do the following: Compile an Android .java file into .class What does the receiver of the .class file have to do to use that .class in their project? (using Eclipse environment) Thank you very much

  • How does one create an elegant iPhone GUI?

    - by jrtc27
    This is just one of those things where you feel like your own design is utterly terrible, and that all of the other apps have a beautiful design. This question is just about how you would go about creating a user interface that a user would actually want to use?

  • Is there a max size for POST parameter content?

    - by l3dx
    I'm troubleshooting a java app where XML is sent between two systems using HTTP POST and a servlet. I suspect that the problem is that the XML is growing way to big. Is it possible that this is the problem? Is there a limit? When it doesn't work, the request.getParameter("message") on the consumer side will return null. Both apps are running on tomcat

  • How do I best catch up with the latest developments in java?

    - by Fredriku73
    I am applying for a job as java developer. I programmed some hobby apps in java until 2001, after that I have mostly worked in c++ and other languages. Meanwhile, it feels like java has grown a lot, and there are all kinds of acronyms (EJB, spring, etc) unknown to me. Where can I find a concise, clear explanation of the recent (5 years) development of java? What are key elements to understand?

  • iPhone Simulating App Update at home before going out in the big bad world

    - by Aran Mulholland
    this is a follow on from this question and the link given it seems that when an app is updated all of the files in the documents directory are copied into the updated apps documents directory and also anything in Library/Preferences. Whats the best way to simulate this for testing purposes? Just copy the files in ApplicationSupport/iPhone Simulator etc? or has anyone developped any funky techniques for testing this.

  • How to show a live Presentation from an Android phone?

    - by Pentium10
    This is not closely related to programming stuff, so I marked as community wiki. I am wondering how can I show a live Presentation from an Android phone? I want to put on a big screen my app, while I am presenting at a conference. I will directly interact with the phone during the presentation and I want the mobile screen visible on the big screen. Are there any apps that does this, or this is possible by the USB cable?

  • Will "Programming in the Cloud" Ever Take off?

    - by Pierreten
    Just got a chance to try out a cloud programming environment that let's you develop .net apps within the browser (http://coderun.com/ide/) I found it pretty interesting, since I was able to develop a mockup ASP.net site on an IPad. With javascript engines in browsers becoming faster and faster, cheap server infrastructure to compile on; will the cloud become the IDE platform of the future?

  • A tool for finding duplicate code in PHP

    - by Toby
    Are there any tools available that can scan multiple .php files and report back duplicated lines/chunks of code? It doesn't have to be really smart but basically give me a starting point for manual scans to improve the codebase of some of my apps.

  • skipping certain number of frames on a timeline

    - by clamp
    hi, i have a mathematical problem which is a bit hard to describe, but i'll give it a try anyway. in a timeline, i have a number of frames, of which i want to skip a certain number of frames, which should be evenly distributed along the timeline. for example i have 10 frames and i want to skip 5, then the solution is easy: we skip every second frame. 10/5 = 2 if (frame%2 == 0) skip(); but what if the above division does result in a floating number? for example in 44 frames i want to skip 15 times. how can i determine the 15 frames which should be skipped? thanks!

  • How messages flows between computers connected with Internet or LAN ?

    - by Praveen
    Hi All, I have been doing Windows programming in .Net since last two years. Now I am shifting to web programming so I just stuck in understanding the fundamentals of web programming, after googling I came to StackOverflow to learn from all of you great guys. My confusion is about how messages flow between systems in distributed enviornment ? I mean suppose I want to send a message "Hello" to a system connected to LAN or Internet, then what will be the steps taken to send the message. Second thing is suppose my system is "A" and I wana send message to system "B" which is connected via a wire, so how the message flows on wire and how system "B" reads it from the wire ? Please someone explain me in a layman terms. Thank you all in advance.

  • Standalone application in C, a good idea?

    - by chutsu
    The term has several definition according to Wikipedia, however what I'm really interested in is creating a program that has all its needed dependencies included within the source folder, so the end user doesn't need to install additional libraries for the app to install. For example, how Mac apps has all its dependencies all within the program itself already... or is there a function that autotools does this? I'm programming in the Linux environment...

  • Should we be giving the client's management team direct access to our git hub repository so that the

    - by SharePoint Newbie
    Hi, We are presently working for a client who is new to working with distributed teams. We have teams spread across India and the UK. Although we have decent project tracking tools (Mingle), would it be a good idea to the give the PM at the client access to our git hub repo. Would this be make it easier for them (see what the devs are working on and an insight into what the team has been developing). I agree that noot all commit messages would make sense to them but would this be a good way to boost their confidence in what we are doing? They already can check out our fortnightly releases on our QA and UA environments, but this still is behind dev by 5-6 days. Also, is there any reporting for git hub which makes it easier for PM types to make sense of it all? Thanks

  • Microphone input

    - by George
    I'm trying to build a gadget that detects pistol shots using Android. It's a part of a training aid for pistol shooters that tells how the shots are distributed in time and I use a HTC Tattoo for testing. I use the MediaRecorder and its getMaxAmplitude method to get the highest amplitude during the last 1/100 s but it does not work as expected; speech gives me values from getMaxAmplitude in the range from 0 to about 25000 while the pistol shots (or shouting!) only reaches about 15000. With a sampling frequency of 8kHz there should be some samples with considerably high level. Anyone who knows how these things work? Are there filters that are applied before registering the max amplitude. If so, is it hardware or software? Thanks, /George
