  • Mouse gestures for Windows with "Rocker" support

    - by Edan Maor
    I'm looking for a mouse gestures program for Windows (including XP). I've seen gMote and StrokeIt, both pretty good, but they're both missing one thing: support for Rocker Gestures. If you don't know it, a Rocker gesture is just holding your right mouse button, then clicking your left (and vice versa). StrokeIt, at least, supports Rocker gestures in one direction, but not the other. Anybody know of a good program that has support for Rocker gestures? Thanks

  • Will this sitemap get me de indexed from Google?

    - by heavy rocker dude
    My site's URL (web address) is: http://quantlabs.net/private/sitemap.xml Description (including timeline of any changes made): Will this sitemap get me de-indexed from Google? My new site map just got spidered by Google for some reason. It is located at http://quantlabs.net/private/sitemap.xml, is this in danger of getting me de-indexed from Google's index. Does it look like spam even though it is not meant to be? I am trying to figure the limitation in terms of Google's threshold before they deem it a spammy sitemap. This is sitemap contains automated postings which are different with the stock symbol provided. The amount of postings within the Sitemap are quite a few in a small amount of time.

  • jquery-autocomplete does not work with my django app.

    - by HWM-Rocker
    Hi everybody, I have a problem with the jquery-autocomplete pluging and my django script. I want an easy to use autocomplete plugin. And for what I see this (http://code.google.com/p/jquery-autocomplete/) one seems very usefull and easy. For the django part I use this (http://code.google.com/p/django-ajax-selects/) I modified it a little, because the out put looked a little bit weired to me. It had 2 '\n' for each new line, and there was no Content-Length Header in the response. First I thought this could be the problem, because all the online examples I found had them. But that was not the problem. I have a very small test.html with the following body: <body> <form action="" method="post"> <p><label for="id_tag_list">Tag list:</label> <input id="id_tag_list" name="tag_list" maxlength="200" type="text" /> </p> <input type="submit" value="Submit" /> </form> </body> And this is the JQuery call to add autocomplete to the input. function formatItem_tag_list(bla,row) { return row[2] } function formatResult_tag_list(bla,row) { return row[1] } $(document).ready(function(){ $("input[id='id_tag_list']").autocomplete({ url:'http://gladis.org/ajax/tag', formatItem: formatItem_tag_list, formatResult: formatResult_tag_list, dataType:'text' }); }); When I'm typing something inside the Textfield Firefox (firebug) and Chromium-browser indicates that ther is an ajax call but with no response. If I just copy the line into my browser, I can see the the response. (this issue is solved, it was a safety feature from ajax not to get data from another domain) For example when I am typing Bi in the textfield, the url "http://gladis.org/ajax/tag?q=Bi&max... is generated. When you enter this in your browser you get this response: 4|Bier|Bier 43|Kolumbien|Kolumbien 33|Namibia|Namibia Now my ajax call get the correct response, but there is still no list showing up with all the possible entries. I tried also to format the output, but this doesn't work either. I set brakepoints to the function and realized that they won't be called at all. Here is a link to my minimum HTML file http://gladis.org/media/input.html Has anybody an idea what i did wrong. I also uploaded all the files as a small zip at http://gladis.org/media/example.zip. Thank you for your help! [Edit] here is the urls conf: (r'^ajax/(?P<channel>[a-z]+)$', 'ajax_select.views.ajax_lookup'), and the ajax lookup channel configuration AJAX_LOOKUP_CHANNELS = { # the simplest case, pass a DICT with the model and field to search against : 'tag' : dict(model='htags.Tag', search_field='text'), } and the view: def ajax_lookup(request,channel): """ this view supplies results for both foreign keys and many to many fields """ # it should come in as GET unless global $.ajaxSetup({type:"POST"}) has been set # in which case we'll support POST if request.method == "GET": # we could also insist on an ajax request if 'q' not in request.GET: return HttpResponse('') query = request.GET['q'] else: if 'q' not in request.POST: return HttpResponse('') # suspicious query = request.POST['q'] lookup_channel = get_lookup(channel) if query: instances = lookup_channel.get_query(query,request) else: instances = [] results = [] for item in instances: results.append(u"%s|%s|%s" % (item.pk,lookup_channel.format_item(item),lookup_channel.format_result(item))) ret_string = "\n".join(results) resp = HttpResponse(ret_string,mimetype="text/html") resp['Content-Length'] = len(ret_string) return resp

  • Complex Django filter question

    - by HWM-Rocker
    Lets say I have this class (simplified): class Tag (...): children = models.ManyToManyField(null=True, symmetrical=False) Now I already implemented the functions get_parents, get_all_ancestors. Is there a nice pythonic way to just the top level tags? If I had designed my Tags differently (to point to the parents instead) I would just make get_all_parents().filter(children=null). My first thought is to create a new function that will go recursively through all parents and save those that has none. But is there a possibility with filters or Query-objects to do the same (with fewer lines of code)? Thanks for your help. [edit] When it is finished, it should be a hierarchical tagging system. Each tag can have children, parents, but only the children are saved. I want to get all the top level tags, that point through many children / childrens children to my tag.

  • Apps with lable XYZ could not be found

    - by HWM-Rocker
    Hello folks, today I ran into an error and have no clue how to fix it. Error: App with label XYZ could not be found. Are you sure your INSTALLED_APPS setting is correct? Where XYZ stands for the app-name that I am trying to reset. This error shows up every time I try to reset it (manage.py reset XYZ). Show all the sql code works. Even manage.py validate shows no error. I already commented out every single line of code in the models.py that I touched the last three monts. (function by function, model by model) And even if there are no models left I get this error. Here http://code.djangoproject.com/ticket/10706 I found a bugreport about this error. I also applied one the patches to allocate the error, it raises an exception so you have a trace back, but even there is no sign in what of my files the error occurred. I don't want to paste my code right now, because it is nearly 1000 lines of code in the file I edited the most. If someone of you had the same error please tell me were I can look for the problem. In that case I can post the important part of the source. Otherwise it would be too much at once. Thank you for helping!!!

  • Strange behavior with complex Q object filter queries in Django

    - by HWM-Rocker
    Hi I am trying to write a tagging system for Django, but today I encountered a strange behavior in filter or the Q object (django.db.models.Q). I wrote a function, that converts a search string into a Q object. The next step would be to filter the TaggedObject with these query. But unfortunately I get a strange behavior. when I search (id=20) = Q: (AND: ('tags__tag__id', 20)) and it returns 2 Taged Objects with the ID 1127 and 132 when I search (id=4) = Q: (AND: ('tags__tag__id', 4)) and it returns also 2 Objects, but this time 1180 and 1127 until here is everything fine, but when i make a little bit more complex query like (id=4) or (id=20) = Q: (OR: ('tags__tag__id', 4), ('tags__tag__id', 20)) then it returns 4(!) Objects 1180, 1127, 1127, 132 But the object with the ID 1127 is returned twice, but thats not the behaviour I want. Do I have to live with it, and uniqify that list or can I do something different. The representation of the Q object looks fine for me. But the worst is now, when I search for (id=20) and (id=4) = Q: (AND: ('tags__tag__id', 20), ('tags__tag__id', 4)) then it returns no object at all. But why? The representation should be ok and the object with the id 1127 is tagged by both. What am I missing? Here are also the relevant parts of the classes, that are involved: class TaggedObject(models.Model): """ class that represent a tagged object """ tags = generic.GenericRelation('ObjectTagBridge', blank=True, null=True) class ObjectTagBridge(models.Model): """ Help to connect a generic object to a Tag. """ # pylint: disable-msg=W0232,R0903 content_type = models.ForeignKey(ContentType) object_id = models.PositiveIntegerField() content_object = generic.GenericForeignKey('content_type', 'object_id') tag = models.ForeignKey('Tag') class Tag(models.Model): ... Thanks for your help

  • How to filter Many2Many / Generic Relations properly with Q?

    - by HWM-Rocker
    Hi, I have 3 Models, the TaggedObject has a GenericRelation with the ObjectTagBridge. And the ObjectTagBridge has a ForeignKey to the Tag Model. class TaggedObject(models.Model): """ class that represent a tagged object """ tags = generic.GenericRelation('ObjectTagBridge', blank=True, null=True) class ObjectTagBridge(models.Model): """ Help to connect a generic object to a Tag. """ # pylint: disable-msg=W0232,R0903 content_type = models.ForeignKey(ContentType) object_id = models.PositiveIntegerField() content_object = generic.GenericForeignKey('content_type', 'object_id') tag = models.ForeignKey('Tag') class Tag(models.Model): ... when I am attaching a Tag to an Object, I am creating a new ObjectTagBridge and set its ForeignKey tag to the Tag I want to attach. That is working fine, and I can get all Tags that I attached to my Object very easy. But when I want to get (filter) all Objects that have Tag1 and Tag2 I tried to something like this: query = Q(tags__tag=Tag1) & Q(tags__tag=Tag2) object_list = TaggedObjects.filter(query) but now my object_list is empty, because it is looking for TaggedObjects that have one ObjectTagBridge with 2 tag objects, the first with Tag1 and the second with Tag2. I my application will be more complex Q queries than this one, so I think I need a solution with this Q object. In fact any combination of binary conjunctions, like: (...) and ( (...) or not(...)) How can I filter this correctly? Every answer is welcome, maybe there is also a different way do achieve this. thx for your help!!!

  • Running Python code from Java program, shoudl i be doing this?

    - by Space Rocker
    i have a scenario where i draw a network and set all it's paraments on swing based gui, after that i have to translate this network into a python based script which another framework reads and realize this network in the form of virtual machines. As an example have look here: from mininet.topo import Topo, Node class MyTopo( Topo ): def *__init__*( self, enable_all = True ): super( MyTopo, self ).__init__() Host = 1 Switch = 2 self.add_node( Switch, Node( is_switch=True ) ) self.add_node( Host, Node( is_switch=False ) ) self.add_edge( Host, Switch ) self.enable_all() topos = { 'mytopo': ( lambda: MyTopo() ) } It simply connects a host to a switch and realize this topology on mininet framework. Now for now in order to realize the drawn network on java GUI here is what i am doing: I simply take the information from GUI and creates a new python file like the one above using java code and then run this file in mininet, which works fine somehow. I want to know, is this the correct and robust way how i am doing this or should i be looking further into java-python bridge like scenarios to be more effective or so as to say more professional.

  • Is there a fast concat method for linked list in Java?

    - by rocker
    How can I concat two linked lists in O(1) with Java via jdk, google or apache commons collection or whatever? E.g. in jdk there is only the addAll method which is O(n). Another feature I miss is to concat two lists where each of them could be in inverse order. To illustrate this assume two lists a-b-c and e-f-g could merged into a-b-c-e-f-g a-b-c-g-f-e c-b-a-e-f-g c-b-a-g-f-e Do you know of such a list implemenation or do I have to implement my own linked list? It would be also helpful to know how to tweak existing solutions (e.g. the jdk LinkedList has a lot of private methods only). These features seems to me very obvious, hopefully I am not missing something stupid.

  • The Power to Control Power

    - by speakjava
    I'm currently working on a number of projects using embedded Java on the Raspberry Pi and Beagle Board.  These are nice and small, so don't take up much room on my desk as you can see in this picture. As you can also see I have power and network connections emerging from under my desk.  One of the (admittedly very minor) drawbacks of these systems is that they have no on/off switch.  Instead you insert or remove the power connector (USB for the RasPi, a barrel connector for the Beagle).  For the Beagle Board this can potentially be an issue; with the micro-SD card located right next to the connector it has been known for people to eject the card when trying to power off the board, which can be quite serious for the hardware. The alternative is obviously to leave the boards plugged in and then disconnect the power from the outlet.  Simple enough, but a picture of underneath my desk shows that this is not the ideal situation either. This made me think that it would be great if I could have some way of controlling a mains voltage outlet using a remote switch or, even better, from software via a USB connector.  A search revealed not much that fit my requirements, and anything that was close seemed very expensive.  Obviously the only way to solve this was to build my own.Here's my solution.  I decided my system would support both control mechanisms (remote physical switch and USB computer control) and be modular in its design for optimum flexibility.  I did a bit of searching and found a company in Hong Kong that were offering solid state relays for 99p plus shipping (£2.99, but still made the total price very reasonable).  These would handle up to 380V AC on the output side so more than capable of coping with the UK 240V supply.  The other great thing was that being solid state, the input would work with a range of 3-32V and required a very low current of 7.5mA at 12V.  For the USB control an Arduino board seemed the obvious low-cost and simple choice.  Given the current requirments of the relay, the Arduino would not require the additional power supply and could be powered just from the USB.Having secured the relays I popped down to Homebase for a couple of 13A sockets, RS for a box and an Arduino and Maplin for a toggle switch.  The circuit is pretty straightforward, as shown in the diagram (only one output is shown to make it as simple as possible).  Originally I used a 2 pole toggle switch to select the remote switch or USB control by switching the negative connections of the low voltage side.  Unfortunately, the resistance between the digital pins of the Arduino board was not high enough, so when using one of the remote switches it would turn on both of the outlets.  I changed to a 4 pole switch and isolated both positive and negative connections. IMPORTANT NOTE: If you want to follow my design, please be aware that it requires working with mains voltages.  If you are at all concerned with your ability to do this please consult a qualified electrician to help you.It was a tight fit, especially getting the Arduino in, but in the end it all worked.  The completed box is shown in the photos. The remote switch was pretty simple just requiring the squeezing of two rocker switches and a 9V battery into the small RS supplied box.  I repurposed a standard stereo cable with phono plugs to connect the switch box to the mains outlets.  I chopped off one set of plugs and wired it to the rocker switches.  The photo shows the RasPi and the Beagle board now controllable from the switch box on the desk. I've tested the Arduino side of things and this works fine.  Next I need to write some software to provide an interface for control of the outlets.  I'm thinking a JavaFX GUI would be in keeping with the total overkill style of this project.

  • Daisy-chaining network switches with multiple cables

    - by user72153
    This might just be the dumbest question you'll ever read, but I digress. Say I have two 100Mbps Ethernet switches with 2 computers on each, connected together by a single cable. This way, the two PCs on each switch share the 100Mbps bandwidth with the others. If I added another cable between the 2 switches, would there be 200Mbps throughput available between the switches? Or am I completely off my rocker? Thanks for the help.

  • Layers - Logical seperation vs physical

    - by P.Brian.Mackey
    Some programmers recommend logical seperation of layers over physical. For example, given a DL, this means we create a DL namespace not a DL assembly. Benefits include: faster compilation time simpler deployment Faster startup time for your program Less assemblies to reference Im on a small team of 5 devs. We have over 50 assemblies to maintain. IMO this ratio is far from ideal. I prefer an extreme programming approach. Where if 100 assemblies are easier to maintain than 10,000...then 1 assembly must be easier than 100. Given technical limits, we should strive for < 5 assemblies. New assemblies are created out of technical need not layer requirements. Developers are worried for a few reasons. A. People like to work in their own environment so they dont step on eachothers toes. B. Microsoft tends to create new assemblies. E.G. Asp.net has its own DLL, so does winforms. Etc. C. Devs view this drive for a common assembly as a threat. Some team members Have a tendency to change the common layer without regard for how it will impact dependencies. My personal view: I view A. as silos, aka cowboy programming and suggest we implement branching to create isolation. C. First, that is a human problem and we shouldnt create technical work arounds for human behavior. Second, my goal is not to put everything in common. Rather, I want partitions to be made in namespaces not assemblies. Having a shared assembly doesnt make everything common. I want the community to chime in and tell me if Ive gone off my rocker. Is a drive for a single assembly or my viewpoint illogical or otherwise a bad idea?

  • What application domains are CPU bound and will tend to benefit from multi-core technologies?

    - by Glomek
    I hear a lot of people talking about the revolution that is coming in programming due to multi-core processors and parallelism, but I can't shake the feeling that for most of us, CPU cycles aren't the bottleneck. Pretty much all of my programs have been I/O bound in one way or another (database, filesystem, network, user interaction, etc.) for a very long time. Now I can think of a few areas where CPU cycles are a limiting factor, like code breaking, graphics, sound, some forms of simulation (weather, physics, etc.), and some forms of mathematical research, but they all seem like fairly specialized application domains. My general impression is that most programs are still I/O bound and that for most of our industry CPUs have been plenty fast for quite a while now. Am I off my rocker? What other application domains are CPU bound today? Do any of them include a large portion of the programming population? In essence, I'm wondering whether the multi-core CPUs will impact very many of us, and if so, how?

  • Entity Framework 4 "Generate Database from Model" to SQLEXPRESS mdf results in "Could not locate ent

    - by InfinitiesLoop
    I'm using Visual Studio 2010 RTM. I want to do model-first, so I started a new MVC app and added a new blank edmx. Created a few entities. No problem. Then I "Generate Database from Model", and allow the dialog to create a new database for me, which it does successfully as 'mydatabase.mdf' in the app's App_Data directory. Then I open the generated sql file (in Visual Studio). To run it of course I have to give it a connection. I am not sure if it's right, but I used '.\SQLEXPRESS' and Windows authentication. No idea how I'd tell it where the MDF is. Then the problem -- upon executing it, I get: Msg 911, Level 16, State 1, Line 1 Could not locate entry in sysdatabases for database 'mydatabase'. No entry found with that name. Make sure that the name is entered correctly. And indeed there were no tables created in the MDF. So... what am I doing wrong, or am I off my rocker expecting this to work? :)

  • Android MediaPlayer ignores it's internal volume when the system volume changes

    - by Daniel Flower
    Hi, here is my situation: I have a media player playing music in an Android application. I've found that with certain headphones, the volume is much too loud even when the volume is set to it's lowest setting. As a result, I want to change the volume of the music for all volume levels to be 10% of what it normally is (actually, this value is user-defined of course). The following works perfectly: mediaPlayer.setVolume(0.1f, 0.1f); The volume of the music is now at a good level for listening. However, if the user now changes the volume using the volume rocker (thus changing the music stream volume), the media player changes the volume as expected, but it also seems to reset the 'setVolume' parameters to 1.0, causing a massive volume change. Setting the volume back to 0.1 sets the volume to how it should be (which is 10% of the current music stream volume). To quote the Android docs for the MediaPlayer.setVolume method: This API is recommended for balancing the output of audio streams within an application How can you do this if it gets reset to 1.0 each time the system volume changes? Any help muchly appreciated. Thanks.

  • Can I autogenerate/compile code on-the-fly, at runtime, based upon values (like key/value pairs) parsed out of a configuration file?

    - by Kumba
    This might be a doozy for some. I'm not sure if it's even 100% implementable, but I wanted to throw the idea out there to see if I'm really off of my rocker yet. I have a set of classes that mimics enums (see my other questions for specific details/examples). For 90% of my project, I can compile everything in at design time. But the remaining 10% is going to need to be editable w/o re-compiling the project in VS 2010. This remaining 10% will be based on a templated version of my Enums class, but will generate code at runtime, based upon data values sourced in from external configuration files. To keep this question small, see this SO question for an idea of what my Enums class looks like. The templated fields, per that question, will be the MaxEnums Int32, Names String() array, and Values array, plus each shared implementation of the Enums sub-class (which themselves, represent the Enums that I use elsewhere in my code). I'd ideally like to parse values from a simple text file (INI-style) of key/value pairs: [Section1] Enum1=enum_one Enum2=enum_two Enum3=enum_three So that the following code would be generated (and compiled) at runtime (comments/supporting code stripped to reduce question size): Friend Shared ReadOnly MaxEnums As Int32 = 3 Private Shared ReadOnly _Names As String() = New String() _ {"enum_one", "enum_two", "enum_three"} Friend Shared ReadOnly Enum1 As New Enums(_Names(0), 1) Friend Shared ReadOnly Enum2 As New Enums(_Names(1), 2) Friend Shared ReadOnly Enum3 As New Enums(_Names(2), 4) Friend Shared ReadOnly Values As Enums() = New Enums() _ {Enum1, Enum2, Enum3} I'm certain this would need to be generated in MSIL code, and I know from reading that the two components to look at are CodeDom and Reflection.Emit, but I was wondering if anyone had working examples (or pointers to working examples) versus really long articles. I'm a hands-on learner, so I have to have example code to play with. Thanks!

  • python eval weirdness
