  • How do I disable auto-compilation of Scala source in jEdit?

    - by Daniel
    I have always liked the auto-compilation feature of jEdit with Scala sources. Now, however, I'm using "mvn scala:cc" and JavaRebel with a Lift project, which provides better compilation than what jEdit does, and I'd like to disable jEdit's auto-compilation. How do I disable auto-compilation in jEdit, of Scala sources, in particular?

  • Ruby in DOS CLI, How to do?

    - by Daniel
    I see in a lot of the tutorials and how to pages, they use the following, or something similar ruby C:\test.rb Which would parse test.rb to the interpreter and ... execute the script. But how is this done a on a windows? Ruby isn't a recognized internal command (as per the DOS output)? I know how to do all these things on Linux, and its as simple as... alas Windows is completely confusing at times :)

  • nfs (netapp) question: how to map the device shown in sar -d to the data volume?

    - by Daniel
    Using sar I can see device nfss24 is very busy, but how to know which data volume (file system) the device is for? sar -d 1 10|egrep "busy|nfs" SunOS phxdbnfs11 5.10 Generic_141414-07 sun4v 04/14/2010 19:03:27 device %busy avque r+w/s blks/s avwait avserv 19:03:28 nfs23 0 0.0 0 0 0.0 0.0 nfs24 100 1484053.4 504 32123 2944300.0 47.5 nfs25 0 0.0 0 0 0.0 0.0 nfs26 0 0.0 0 0 0.0 0.0 nfs27 107 1.1 0 0 0.0 0.0 nfs28 107 17.0 0 0 0.0 0.0 nfs29 100 13109.5 460 29435 28451.7 52.0 nfs30 0 0.0 0 0 0.0 0.0 nfs31 107 9.6 0 0 0.0 0.0 nfs32 0 0.0 0 0 0.0 0.0 nfs33 107 1.1 0 0 0.0 0.0 19:03:29 nfs23 0 0.0 0 0 0.0 0.0 nfs24 100 1483762.8 530 33709 2797054.5 45.1 nfs25 0 0.0 0 0 0.0 0.0 nfs26 0 0.0 0 0 0.0 0.0 nfs27 107 1.1 0 0 0.0 0.0 nfs28 107 17.0 0 0 0.0 0.0 nfs29 100 12800.8 511 32732 25016.0 46.8 nfs30 0 0.0 0 0 0.0 0.0 nfs31 107 9.6 0 0 0.0 0.0 nfs32 0 0.0 0 0 0.0 0.0 nfs33 107 1.1 0 0 0.0 0.0 19:03:30 nfs23 0 0.0 0 0 0.0 0.0 nfs24 100 1483080.4 761 48162 1950073.8 31.4 nfs25 0 0.0 0 0 0.0 0.0 nfs26 0 0.0 0 0 0.0 0.0 nfs27 107 1.1 0 0 0.0 0.0 nfs28 107 17.0 0 0 0.0 0.0 nfs29 100 12406.7 737 46855 16800.7 32.4 nfs30 0 0.0 0 0 0.0 0.0 nfs31 107 9.6 0 0 0.0 0.0 nfs32 0 0.0 0 0 0.0 0.0 nfs33 107 1.1 0 0 0.0 0.0

  • Disk-based caching of dynamic images in IIS 7

    - by Daniel Schierbeck
    I'm writing an image server which needs to handle a relatively large number of concurrent requests (~5,000). The images being served are dynamically scaled down and cropped based on per-image specifications, which are queried from a database. The number of images is rather large, so an in-memory cache isn't viable (thrashing would most definitely occur). I'm using native caching in IIS 7 to avoid hitting the ASP.NET app which generates the images on-the-fly. I've looked around, but I couldn't find a simple way to configure IIS to store the cache on-disk -- is there such an option, or would I need to roll my own? I'd rather avoid placing the generated images in a public folder, so they can be served statically, since I would prefer to invalidate the cache entries using a query parameter (last-edit time from the database,) which doesn't seem possible to reconcile with static caching. I would love to get some feedback on this!

  • Open Office Impress

    - by Daniel Ray
    Hi I have seen that in some question around presentation you suggest using OO Impress for this. I am trying to show multiple presentation in a non fullscreen window, but havent been very successful so far. Ideally I want to be able to move this presentation windows around the screen. I have searched the Open Office forum but the is almost nothing concerning this topic and noone seems to know the answer to my question. Im trying to do this in C#. I would be very thankfull if you can give me some directions, how to do this. Thank you

  • Detecting whether user stayed after prompting onBeforeUnload

    - by Daniel Magliola
    In a web app I'm working on, I'm capturing onBeforeUnload to ask the user whether he really wants to exit. Now, if he decides to stay, there are a number of things I'd like to do. What I'm trying to figure out is that he actually chose to stay. I can of course declare a SetTimeout for "x" seconds, and if that fires, then it would mean the user is still there (because we didn't get unloaded). The problem is that the user can take any time to decide whether to stay or not... I was first hoping that while the dialog was showing, SetTimeout calls would not fire, so I could set a timeout for a short time and it'd only fire if the user chose to stay. However, timeouts do fire while the dialog is shown, so that doesn't work. Another idea I tried is capturing mouseMoves on the window/document. While the dialog is shown, mouseMoves indeed don't fire, except for one weird exception that really applies to my case, so that won't work either. Can anyone think of other way to do this? Thanks! (In case you're curious, the reason capturing mouseMove doesn't work is that I have an IFrame in my page, containing a site from another domain. If at the time of unloading the page, the focus is within the IFrame, while the dialog shows, then I get the MouseMove event firing ONCE when the mouse moves from inside the IFrame to the outside (at least in Firefox). That's probably a bug, but still, it's very likely that'll happen in our case, so I can't use this method).

  • DirectShow EVR resizing window problem

    - by Daniel
    So I've been looking into the world of media playback for windows and I've started making a C# Media Player using DirectShow. I started off using the VRM-7 windowed video renderer and it was brilliant except it had a couple of small problems (multi monitors, fullscreen). But after some research I found that it's deprecated and I should be using VRM9. So I changed it to use VRM9 windowless then found out that was an old post rofl _< so finally I'm using Vista/Win7 (or XP .net 3) Enhanced Video Renderer (EVR) which is apparently the most up to date Microsoft video renderer and has all the flashy performance/quality things added to it. (tbh I haven't noticed any difference but maybe I need a blue-ray or HQ video to notice it). With using EVR everything is working fine except resizing the video. Its really laggy/choppy/teary and probably something to do with its frame queueing mechanism. To demonstrate my problem open up windows media player classic. View - Options - Playback - output Chose the "EVR" DirectShow Video renderer Now restart wmp class and play a video, while it's playing click and drag a corner to resize it. You'll notice its horribly laggy. This is the exact same problem i am having. But if you chose "EVR Custom Pres. *" or EVR Sync *" resizing works beautifully! So i tried googling around for anything about EVR resizing issues and how to fix it but i couldn't believe how little i could find. I'm guessing "Custom Pres." stands for "Custom Presenter" which sounds like they made their own. Also you'll notice on the right hand size when you swap between EVR and the other EVR's the Resizer drop down on the right greys out. So basically I wan't to know how I can fix this retarded resizing problem and is there any decent documentation out there? There is a fair bit for VMR7/9 but not much for EVR. I downloaded the DirectX SDK which apparently has samples but it was a waste of 500mb of bandwidth as it had nothing relevant. Perhaps there is some way to force it not queueing up frames if that is the problem? If you want code say the word and I'll paste some in. But it's really quite simple and nothing much happens, i'm convinced it's a problem with the EVR renderer. EDIT: Oh and one other thing, what does VLC use? If you go into vlc options and change the renderer to anything but default, they all suck. So is it using VMR7? Or its own?

  • How to set the Windows Mobile 6 IME mode (to numbers only)

    - by Daniel Crenna
    In Windows Mobile 5 one of the following methods works to set an input to numbers only: // Managed InputModeEditor.SetInputMode(textBox, InputMode.Numeric); // Native Wrapper InputModeSupport.SHSetImeMode(textBox.Handle, InputModeSupport.SHIME_MODE.SHIME_MODE_NUMBERS); In Windows Mobile 6, neither works. How do you set the IME to "Numbers Only" in WM 6.0 / .NET CF 3.5?

  • Modify strings in Rails?

    - by Daniel O'Connor
    Hey everyone, So I'm new to Rails (teaching myself as a senior project in high school), and I'm trying to figure out how to modify these strings. Let's say someone writes the following string in a form: "you know you are a geek when" How can I automatically change it to this: "You know you are a geek when..."? I need Rails to check the case of the first letter and check for the three dots then modify the string as necessary. I've looked here, but I can't find anything that would work. Thanks a lot!

  • Server is on or off

    - by Daniel
    Curious. I'm starting to broadcast high school football games online, and it uses a program to broadcast the feeds off my computer. However, when I shut the program down or the computer down, the server goes offline and guests won't be able to access the feeds. Is there any kind of code out there that I can post onto my website that will indicate to my guests whether the server is on or off? I would figure it would be a simple code, a php script or something that periodically checks to see if a site is on line and then displays ON or OFF.

  • Print out PDF with javascript [closed]

    - by Daniel Abrahamsson
    I have a need to print out multiple PDFs with the help of javascript. Is this even possible without rendering each PDF in a separate window and calling window.print()? Basically, I would like to be able to do something like print('my_pdf_url'). Edit After some searching, I have come to the conclusion that there are no other methods than the one I've described above. It is a far from perfect solution, but it works in simple cases. Edit I ended up merging the PDFs to a monster PDF on the server side and then send this single PDF to the user, who can then choose to print it out.

  • How stable are Cisco IOS OIDs for querying data with SNMP across different model devices?

    - by Daniel Papasian
    I'm querying a bunch of information from cisco switches using SNMP. For instance, I'm pulling information on neighbors detected using CDP by doing an snmpwalk on .1.3.6.1.4.1.9.9.23 Can I use this OID across different cisco models? What pitfalls should I be aware of? To me, I'm a little uneasy about using numeric OIDs - it seems like I should be using a MIB database or something and using the named OIDs, in order to gain cross-device compatibility, but perhaps I'm just imagining the need for that.

  • Programmer tendency to preach [closed]

    - by Daniel
    I've run across several SO posts that come across as preachy or condescending. Do pedagogical programmers feel plagued by thoughtless questions? Or, do programmers count self-sufficiency such a virtue that any perceived lack of ambition merits scolding? These are some theories, admittedly negative ones. Can anyone offer some insight?

  • JNI - GetObjectField returns NULL

    - by Daniel
    I'm currently working on Mangler's Android implementation. I have a java class that looks like so: public class VentriloEventData { public short type; public class _pcm { public int length; public short send_type; public int rate; public byte channels; }; _pcm pcm; } The signature for my pcm object: $ javap -s -p VentriloEventData ... org.mangler.VentriloEventData$_pcm pcm; Signature: Lorg/mangler/VentriloEventData$_pcm; I am implementing a native JNI function called getevent, which will write to the fields in an instance of the VentriloEventData class. For what it's worth, it's defined and called in Java like so: public static native int getevent(VentriloEventData data); VentriloEventData data = new VentriloEventData(); getevent(data); And my JNI implementation of getevent: JNIEXPORT jint JNICALL Java_org_mangler_VentriloInterface_getevent(JNIEnv* env, jobject obj, jobject eventdata) { v3_event *ev = v3_get_event(V3_BLOCK); if(ev != NULL) { jclass event_class = (*env)->GetObjectClass(env, eventdata); // Event type. jfieldID type_field = (*env)->GetFieldID(env, event_class, "type", "S"); (*env)->SetShortField( env, eventdata, type_field, 1234 ); // Get PCM class. jfieldID pcm_field = (*env)->GetFieldID(env, event_class, "pcm", "Lorg/mangler/VentriloEventData$_pcm;"); jobject pcm = (*env)->GetObjectField( env, eventdata, pcm_field ); jclass pcm_class = (*env)->GetObjectClass(env, pcm); // Set PCM fields. jfieldID pcm_length_field = (*env)->GetFieldID(env, pcm_class, "length", "I"); (*env)->SetIntField( env, pcm, pcm_length_field, 1337 ); free(ev); } return 0; } The code above works fine for writing into the type field (that is not wrapped by the _pcm class). Once getevent is called, data.type is verified to be 1234 at the java side :) My problem is that the assertion "pcm != NULL" will fail. Note that pcm_field != NULL, which probably indicates that the signature to that field is correct... so there must be something wrong with my call to GetObjectField. It looks fine though if I compare it to the official JNI docs. Been bashing my head on this problem for the past 2 hours and I'm getting a little desperate.. hoping a different perspective will help me out on this one.

  • Which is better? OpenCyc or ConceptNet?

    - by Daniel Loureiro
    Hi, I'm doing a NLP project where I need to recognise concepts in sentences to find other similar concepts. I do this to infer word valences from a list I already have. I started using WordNet, but it gave many contradictory results. By contradictory results I mean word expansions that had contradictory valences. So now I'm looking into ConceptNet and OpenCyc. I've already implemented ConceptNet and it was all very easy and I love it. Problem is that OpenCyc appears to have a much larger and more logically rigid database, which is important when I found so many "contradictions" on WordNet... But I wouldn't know because I haven't tried it. Could someone tell me if it's worth going through the (considerable, for me) effort to implement OpenCyc, or is ConceptNet good enough to infer word valences? Are they that different? I'll be happy to explain myself further, if needed. Trying to keep it short for now! Thanks!

  • Problems with ASP.NET, machine-level web.config, and the location element

    - by Daniel Schaffer
    I've got a server running Windows Web Server 2008 R2. The machine-level web.config has the following entries: <location path="Preview"> <appSettings> <add key="Environment" value="Preview" /> </appSettings> </location> <location path="Staging"> <appSettings> <add key="Environment" value="Staging" /> </appSettings> </location> <location path="Production"> <appSettings> <add key="Environment" value="Production" /> </appSettings> </location> I have a website that I'd set up in the direction D:\Sites\Preview\, so the full path would be D:\Sites\Preview\WebSite1. If I put a simple aspx file that just outputs the value of ConfigurationManager.AppSettings["Environment"], it displays the value Preview. I'm not clear on exactly how that works, but it does. I'd set this up several weeks ago, and just now tried to duplicate this - I put a second site in the D:\Sites\Preview\ directory, expecting that it would automatically pick up the appropriate appSettings entries, but for some reason it hasn't - the same aspx page doesn't show anything. Additionally, when I go into the IIS manager and open the Configuration Editor, there are no settings in there, whereas there are settings listed for the first site. Any ideas as to what I could be missing? Is the location element intended to work like this, or did I just find some magical fluke with my first site?

  • ASP.NET DropDownList posting ""

    I am using ASP.NET forms version 3.5 in VB I have a dropdownlist that is filled with data from a DB with a list of countries The code for the dropdown list is <label class="ob_label"> <asp:DropDownList ID="lstCountry" runat="server" CssClass="ob_forminput"> </asp:DropDownList> Country*</label> And the code that the list is Dim selectSQL As String = "exec dbo.*******************" ' Define the ADO.NET objects.

For some reason the dropdownlist is posting "" rather than the value for the selected country.
