  • Change color on single-series line chart using rCharts and Highcharts?

    - by Sharon
    Is it possible to change the color of a line using rCharts and Highcharts so that the line color changes depending on a factor? I've done this with ggplot2 but would like to make an interactive version if possible. I've tried h1 <- Highcharts$new() h1$chart(type="line") h1$series(data=mydf$myvalue, name="", groups = c("myfactor")) h1$xAxis(tickInterval = 4, categories = mydf$myXaxis) but that's not working, line stays the same color. Sample data myvalue <- c(16, 18, 5, 14, 10) myXaxis <- c(1,2,3,4,5) myfactor <- c("old", "old", "old", "new", "new") mydf <- data.frame(myvalue, myXaxis, myfactor) Thanks for any suggestions.

  • Android: videocamera, limit length of videos taken

    - by AP257
    I'm working in Android and starting the video camera activity using ACTION_VIDEO_CAPTURE. Is there any way I can limit the length (in time) of the videos the user can take? I think this is possible if you use MediaRecorder, but I don't really fancy doing that since it's so much more complicated than using the simple ACTION_VIDEO_CAPTURE. Current code: Intent videoCaptureIntent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE); startActivityForResult(videoCaptureIntent,1); If it's not possible, does anyone know whether I could set a timer (TimerTask?) in Java and then show a Toast message after a certain length of time warning the user that they need to stop filming? (I'm a Java newbie, so I don't know if this is exactly what I need.)

  • What's the easiest way to sort an EF4 EntityCollection<T>?

    - by Will
    I'd love to add some sorting to an EntityCollection that is bound to an ItemsControl (in xaml). I'd also like to do it as simply as possible. It appears that this is not possible. If I wrap the collection in a "sorted" version of the collection property within the Entity I lose collection change notifications. I can't use a CollectionViewSource because the entity collection's BindingListCollectionView does not support sorting for some goddamned reason (note: I've seen the blog post with the "dirty" hack to get around this, so please don't answer with that kthx). Is there a simple (couple lines of xaml, couple lines of code, whatever) way to achieve this??

  • Overriding a function in Emacs Lisp

    - by scrapdog
    I would like to temporarily override the kill-new function. I have a way I want to reimplement kill-new that works in only in certain contexts, but I don't want to reimplement a special version of kill-region on top of that. (kill-new is called from kill-region) Since Emacs Lisp uses dynamic scoping, this should be possible, right? (On the other hand, it seems that this would be an unsafe thing to support, and it might make me a bit nervous knowing that it is possible...) I have experimented with using let and fset, but so far have found no way to get it to work as expected. So, hopefully someone can fill in the blank in the following pseudocode: (defun my-kill-new (string &optional replace yank-handler) (message "in my-kill-new!")) (defun foo () (some-form-that-binds-a-function (kill-new my-kill-new) (kill-region (point) (mark)))) What should some-form-that-binds-a-function be? Or am I barking up the wrong tree?

  • Cocoa NSStatusBar Global HotKey

    - by Craig
    I have created an NSStatusBar cocoa application which sits in the system status bar. I want to assign a hotkey so that when pressed it toggles my applications and show the menu. Is this possible?, In my searching and experimenting I have found a few different ways of assigning global hot keys that can be pressed when your application is in the background but I can't find any way to problematically make the menu show. Is this possible?, If anyone thinks a way of assigning a global hotkey is best please post it. Thanks. One of the hotkey tutorials I found was on http://dbachrach.com/blog/2005/11/program-global-hotkeys-in-cocoa-easily/ for anyone interested.

  • In Eclipse, how to open a file browser in the directory of the currently edited file

    - by JC
    Hi, I know it's possible in eclipse to open file browsers from your project's resource browser, but is it possible for files that aren't part of your project ? Typically external includes are not found in your resource browser... If there is the equivalent of $(resource_loc) for the editor, it would work.. But I wasn't able to find it. Can anyone help me on this ? thanks! JC EDIT : I Found StartExplorer, but it's a joke of a plug-in. It is hardcoded to use WINDOWS explorer or cmd.exe. Also, it still requires you to use the resource browser. Other than that it can open paths selected in the editor, but they must be full paths.

  • Implementing fallback from Google AJAX Libraries API to local jQuery

    - by Maxim Z.
    After looking up the advantages and disadvantages of using Google's AJAX Libraries API instead of using jQuery locally, I saw that someone wrote in an answer (here on Stack Overflow, of course) that it's possible to get around the downtime that Google's API sometimes experiences by somehow falling back to a local copy of the library you use. I want to use Google's AJAX Libraries API on my site, but I'm concerned about this possible downtime and I'm curious how such a fallback procedure can be implemented. Has anybody ever tried doing this? Can you point me towards some code that accomplishes such a feat? Thanks in advance.

  • nmake.exe: is there a way to exclude a file from a set of files specified in a macro?

    - by Cheeso
    I'm looking for something like the Exclude filter for msbuild, but I Want it in a makefile processed by nmake. Is that possible? Suppose I have a makefile that defines this macro: SOURCES=xxx.c yyy.c zzz.c and I invoke it with nmake OLD=xxx.c NEW=bbb.c ...can I produce, within the makefile, a macro with a value like: yyy.c zzz.c bbb.c ...basically substituting bbb.c for xxx.c ? The files can appear in any order. This would be pretty easy if the string substitution that is possible in nmake macros, allowed for evaluation of macros. In other words, I can do sources=xxx.c yyy.c zzz.c objs=$(sources:.c=.o) and the value of $(objs) is xxx.o yyy.o zzz.o But nmake does not allow a macro for the value of either argument to that substitution. I cannot do this: new=.o sources=xxx.c yyy.c zzz.c objs=$(sources:.c=$(new))

  • Running Awk command on a cluster

    - by alex
    How do you execute a Unix shell command (awk script, a pipe etc) on a cluster in parallel (step 1) and collect the results back to a central node (step 2) Hadoop seems to be a huge overkill with its 600k LOC and its performance is terrible (takes minutes just to initialize the job) i don't need shared memory, or - something like MPI/openMP as i dont need to synchronize or share anything, don't need a distributed VM or anything as complex Google's SawZall seems to work only with Google proprietary MapReduce API some distributed shell packages i found failed to compile, but there must be a simple way to run a data-centric batch job on a cluster, something as close as possible to native OS, may be using unix RPC calls i liked rsync simplicity but it seem to update remote notes sequentially, and you cant use it for executing scripts as afar as i know switching to Plan 9 or some other network oriented OS looks like another overkill i'm looking for a simple, distributed way to run awk scripts or similar - as close as possible to data with a minimal initialization overhead, in a nothing-shared, nothing-synchronized fashion Thanks Alex

  • How get all calendar entries for a given using the Notes.Jar for Java

    - by vikramjb
    I am working on a simple java code to extract all calendar entries for a given date. I know it possible using Domingo but I would like to use only Notes.jar for this purpose. It is possible for me to create a session based on a given credentials and get the calendar object. I am looking to extract the current running notes session and use that session object to open the calendar view in the mail file and start playing with it. But I am not able to get it working. Anybody have any idea or links on this ?

  • GWT Post build command in Eclipse

    - by Henrik
    I am starting getting used to Eclipse, but I have much more experience with Visual Studio. In Visual Studio it is possible to run auto commands after the build has finished. Now I am creating a GWT project and several other projects at once in one solution (or workspace) in Eclipse. Some files which are compiled with the GWT project needs to be copied to another location when they have been compiled. I am currently doing this manually and would like to do it automatically. I am not doing it often, since the project works fine in debug mode (...?gwt.codesvr=localhost:9997). But where is the location for executing a post build command for a GWT project in eclipse? Is it possible?

  • Streaming server required with JW Player?

    - by Aaron
    Currently, a site I developed plays mp3 files directly in JW Player using the file attribute and public URLs to the mp3 file. This is now an issue with the client for legal reasons, and they now need to stream the audio files so that the users can't open up their cache and nab the files directly after downloading. The JW player site has a bunch of examples for streaming video, but nothing for audio. Is it possible to stream audio files with JW player, and do we have to pay a lot of money for a streaming provider? Is it possible to do on the local php server?

  • PHP 2D Array output all combinations

    - by stukerr
    Hi there, I've had this problem bending my mind for a while now (head cold doesn't help either!), basically I have a PHP array which looks like this example: $array[0][0] = 'apples'; $array[0][1] = 'pears'; $array[0][2] = 'oranges'; $array[1][0] = 'steve'; $array[1][1] = 'bob'; And I would like to be able to produce from this a table with every possible combination of these, but without repeating any combinations (regardless of their position), so for example this would output Array 0 Array 1 apples steve apples bob pears steve pears bob But I would like for this to be able to work with as many different arrays as possible. Many thanks!

  • How to inject JPA EntityManager using spring

    - by marcos
    Hello all! I have a few questions about jpa + spring integration running on tomcat, i've been looking fo some time and couldn't find any concrete answer, so here it goes: Is it possible to have spring to inject the JPA entityManager object into my DAO class without extending JpaDaoSupport? if yes, does spring manage the transaction in this case? I'm trying to keep spring configuration as simple as possible: <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"> <property name="entityManagerFactory" ref="em"/> </bean> <bean id="em" class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean"> <property name="persistenceUnitName" value="myPU"/> </bean> EDIT: that was very helpfull, thank you all!

  • Creating colour schemes based on an existing scheme

    - by Neil Barnwell
    I have a colour scheme based around yellow, for warning messages on a website. It amounts to a slightly orange bordered box, with a pale yellow fill. The exact colours are: #FED626 (border) #FFF7C0 (fill) I want to know if it's possible to convert this scheme mathematically or algorithmically somehow, to come up with a blue version where the border is the "same amount" of blue as this one is yellow. Is this possible, or do I just "pin the tail on the donkey" on a colour pallet to get roughly the right one? I ask, because I'd quite like to be able to calculate this on the fly, to perhaps implement something in .less. To give you an idea, I tried swopping the red and blue values on those two, and came up with this: #26D6FE (border) #C0F7FF (fill) That wasn't too hard, but think about if I wanted a pink colour scheme... :)

  • AS3 Event Bubbling outside of the Scenegraph/DisplayList

    - by Brian Heylin
    Hi just wondering if it is possible to take advantage of event bubbling in non display list classes in AS3. For example in the model of an application where there is a City class that contains many Cars. What methods are there to attach an event listener to a City object and receive events that bubble up from the child Cars. To clarify The City and Car objects are not part of the display list, they are not DisplayObjects. So can bubbling be implemented outside of the display list somehow? As far as I know, this is not possible without manually attaching event listeners to each Car object and re dispatching the event from the City object. Anyone else have a cleaner solution?

  • Spring Weblfow 2 - Double Submit

    - by John W.
    Hello All, I am investigating a possible issue with double submits and I am looking at the possibilty of a double submit from a webflow execution. I have read many times that webflow will handle double submits, there are plenty references here. However I then came across I a forum response on the spring source forums contradicting what I read saying, SWF synchronizes on the conversation. Only one request will be processed at a time per conversation. Take note that if you're using snapshots, then it's possible repeatedly clicking on the submit button will generate a second request. I would recommend setting history to invalidate or discard in the transition from your view-state. We do have snapshots enabled but the book notes that using snapshots actually allows to solve the double submits. Does anyone have any insight on this? Thanks.
