• FireFox Toolbar Open Window in new Tab

  - by Mark

  Hi all, I have a Toolbarbutton <toolbarbutton context="TabMenue" id="esbTb_rss_reader" label="News" type="menu"> with a Context menue which comes up when the button is right clickt <menupopup id="TabMenue" > <menuitem label="New Tab" oncommand="esbTb_loadURLNewTab()"/> </menupopup> so this function should open the new window in a new tab function esbTb_loadURLNewTab() { window.open(ClickUrl,'name'); } I don't get it working that the new Window is showing up in a new tab it always opens a new firefox window. I tried also like described in this article to set the browser.link.open_newwindow and browser.link.open_newwindow.restriction preferences but that doesn't bringt anything. And I tried it with all Target attributes which came in my mind. So I'm grateful for any hints, tips what ever this is driving me crazy...

• Resizing Ubuntu x64 Server Partition with VirtualBox not reflected in OS

  - by daleyjem

  I've already resized my virtual disk with VirtualBox, but now need to extend the partition of my Ubuntu VM itself. I thought I was on my way with GParted live CD, but after I resize the "extended" filesystem partition, and then the child "lvm2 pv" filesystem partition to fill the unallocated space, df -h still shows the original disk size after I reboot into the VM. Any tips on this? I've scoured the webs tirelessly. Should I be resizing the boot (/dev/sda1) partition instead? Should I try to convert my lvm2 to ext4 or something? I'm lost on this. Note: VirtualBox hard disk is "dynamic". Specs: VBox 4.2.18 Ubuntu 12.04.2 amd64 Gparted 0.16.2-1b-i486

• @Path and regular expression (Jersey/REST)

  - by Castanho

  Hi there! I'm using Jersey in a REST project and I'm needing to use regular expression. Digging about it is simple like: @Path("/resources) public class MyResource { @GET @Path("{subResources:.*}/bar") public String get() {...} } But, I'm only capable of using regex if in my @Path contains a variable or text value, example: @Path("{SubResource1}/{subResources:.*}/bar") Or @Path("hardCodeString/{subResources:.*}/bar") Today I could run with this solution of a variable, but is not oK for my perspective. Question Does anyone have worked with something related? I'm doing something wrong? I think that this could be a bug, when working with more then one @Path, one in the Class and other in the Method. Any tips is appreciated! Regards

• Create tables for a dictionary?

  - by heffaklump

  I'm making a dictionary database in SQLite and need some tips. My SQL is a bit rusty ;) Would you consider this good SQL? It's done with Java JDBC. This is for creating the tables. CREATE TABLE word ( id INTEGER, entry STRING, pos STRING ); CREATE TABLE translation ( word_id INTEGER REFERENCES word(id), entry STRING ); And when filling with data i give each word a number (id) and that words translations get the same number as word_id. What would be the best way of pulling out translations for a specific word?

• How to Handle Console.log and error output in JavaScript.

  - by uber_n00b

  I have a constructor that has a series of classes and functions within it - in each function I check if the param is set to show the error and output if so. Like so using an inline if. The issue and question is short of keeping two versions is this approach not wise in that each IF has to be evaluated thus adding to the time it takes to perform? debugSlide = (bag.debug==1)? console.log("item id =" + bag.itemId) : 0; How do you do this? Any pointers on where I can find tips on this? Thanks in advance!

• Forward email to Tumblr

  - by Fenrir

  I am trying to filter/forward emails from a gmail account to a tumblr blog. I have created the tumblr blog and set it up to receive emails via a tumblr email address as seen here: http://www.tumblr.com/docs/en/email_publishing#can The problem is that, as stated by the tumblr email set-up page: "What if I’m having trouble with email publishing? A few tips: Send posts directly to your mobile posting email address. You cannot email another email address and then forward the email from there." This appears to make filtering emails from a gmail account impossible. Anyone know of work around for this?

• Get "2:35pm" instead of "02:35PM" from Python date/time?

  - by anonymous coward

  I'm still a bit slow with Python, so I haven't got this figured out beyond what's obviously in the docs, etc. I've worked with Django a bit, where they've added some datetime formatting options via template tags, but in regular python code how can I get the 12-hour hour without a leading zero? Is there a straightforward way to do this? I'm looking at the 2.5 and 2.6 docs for "strftime()" and there doesn't seem to be a formatting option there for this case. Should I be using something else? Feel free to include any other time-formatting tips that aren't obvious from the docs. =)

• What can we do to make XML processing faster?

  - by adpd

  We work on an internal corporate system that has a web front-end as one of its interfaces. The front-end (Java + Tomcat + Apache) communicates to the back-end (proprietary system written in a COBOL-like language) through SOAP web services. As a result, we pass large XML files back and forth. We believe that this architecture has a significant impact on performance due to the large overhead of XML transportation and parsing. Unfortunately, we are stuck with this architecture. How can we make this XML set-up more efficient? Any tips or techniques are greatly appreciated.

• Python finding repeating sequence in list of integers?

  - by tijko

  I have a list of lists and each list has a repeating sequence. I'm trying to count the length of repeated sequence of integers in the list: list_a = [111,0,3,1,111,0,3,1,111,0,3,1] list_b = [67,4,67,4,67,4,67,4,2,9,0] list_c = [1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0,23,18,10] Which would return: list_a count = 4 (for [111,0,3,1]) list_b count = 2 (for [67,4]) list_c count = 10 (for [1,2,3,4,5,6,7,8,9,0]) Any advice or tips would be welcome. I'm trying to work it out with re.compile right now but, its not quite right.

• Submit form without page reloading

  - by Camran

  I have a classifieds website, and on the page where ads are showed, I am creating a "Send a tip to a friend" form... So anybody who wants can send a tip of the ad to some friends email-adress. I am guessing the form must be submitted to a php page right? <form name='tip' method='post' action='tip.php'> Tip somebody: <input name="tip_email" type="text" size="30" onfocus="tip_div(1);" onblur="tip_div(2);"/> <input type="submit" value="Skicka Tips"/> <input type="hidden" name="ad_id" /> </form> When submitting the form, the page gets reloaded... I don't want that... Is there any way to make it not reload and still send the mail? Preferrably without ajax or jquery... Thanks

  - by EquinoX

  I know there's a lot of resource for this via google, but I just wanted to hear personally from people who have experienced this before. I've programmed in C for 3 years and C++ for a year and now I am moving to C#. I know this is not going to be a so hard transition but could you guys that had this same experience with me share resources on a good book, article, or blog to make my study experience more efficient. Any tips/tricks or gotchas when moving to C#? Here's one article that I can find via google. Looking for more goodies from experienced developers here.

• code setOnClickListener for multiple TextViews

  - by user2870583

  I have 40+ TextViews and I want to add click events on them, but I try to do it "shortly" : final GridLayout myGL; myGL = (GridLayout) v0725.findViewById( R.id.tab1 ); for( int i = 0; i < myGL.getChildCount(); i++ ) if ( getResources().getResourceEntryName(((TextView) myGL.getChildAt(i)).getId()).indexOf("v")==0 ) { ((TextView) myGL.getChildAt(i)).setOnClickListener(new View.OnClickListener() { public void onClick(View v) { Log.v("edf", getResources().getResourceEntryName(((TextView) myGL.getChildAt(i)).getId())); } }); }; But Eclipse stops me on the Log.v line, because i should be final (but I can't) any tips?

• Search box inside a div. Django

  - by Juliette Dupuis

  In my django app I display a list of elements (friends name) thanks to a loop: <div> {% for friend in group %} <p>{{ friend.name }} <p> {% endfor %} </div> I would like to create a search box on the top of my list in order to be able to find only the friends the user wants. I would like the search bar does not need to click to send the request (an example is the Airtime searchbox on top of the facebook friends list). I have absolutely no idea on how to do that, and I'm looking for hints or tips to start. Thank you very much for your help.

• can constructors actually return Strings?

  - by elwynn

  Hi all, I have a class called ArionFileExtractor in a .java file of the same name. public class ArionFileExtractor { public String ArionFileExtractor (String fName, String startText, String endText) { String afExtract = ""; // Extract string from fName into afExtract in code I won't show here return afExtract; } However, when I try to invoke ArionFileExtractor in another .java file, as follows: String afe = ArionFileExtractor("gibberish.txt", "foo", "/foo"); NetBeans informs me that there are incompatible types and that java.lang.String is required. But I coded ArionFileExtractor to return the standard string type, which is java.lang.string. I am wondering, can my ArionFileExtractor constructor legally return a String? I very much appreciate any tips or pointers on what I'm doing wrong here.

• C# chart control Performance with large amounts of data

  - by user3642115

  I am using a chart control with a range bar graph to basically make a gantt chart for lots of people and lots of projects, say about 1000 total series. The issue that I am running in to is that once I have all my data added to the chart, which takes some time but that is to be expected, and I go to scroll down on my graph it freezes the whole application and takes a while before it unfreezes and scrolls down. Is there any way to improve the performance of this? I tried adding the graph to a panel and growing the graph size dynamically and then scrolling down from the panel but that cause a whole plethora of other issues. Any tips for speeding this up? I don't think it is my code as it has already finished running when this issue happens. Thanks.

• Merging elements in a scala list

  - by scompt.com

  I'm trying to port the following Java snippet to Scala. It takes a list of MyColor objects and merges all of the ones that are within a delta of each other. It seems like a problem that could be solved elegantly using some of Scala's functional bits. Any tips? List<MyColor> mergedColors = ...; MyColor lastColor = null; for(Color aColor : lotsOfColors) { if(lastColor != null) { if(lastColor.diff(aColor) < delta) { lastColor.merge(aColor); continue; } } lastColor = aColor; mergedColors.add(aColor); }

• Read external HTML page and then find data within

  - by inthewayboy

  I'm playing around with an idea, and I'm stuck at this one part. I want to read an external HTML page and then extract the data held within two <dd> tags. I've been using file_get_contents with good results, but I'm at a loss as to how to accomplish that last part. The two tags I want to extract the value from are always enclosed within a particular <div>, was wondering if that might help? In my mind it reads the entire html file into a string, then dumps all the data up until this one particular <div>, and dumps all the data after the closing </div>. Is that possible? I think this needs regex syntax which I've never used yet. So any tips, links, or examples would be great! I can provide more info as necessary.

• Creative an interactive GUI for a web application

  - by user2125844

  I have to create a web application (preferably using the Google App Engine) that will allow users to access it through a url link (not a Desktop application). The application graphically looks like a flow chart and each item in the chart can be selected to pull up a video (not in another window). It is recommended that I use Python. I have never made anything for the web before. Is there a best Python GUI API I should use? I've read quite a bit about Django so far I'm not sure if it is the best fit for this or not. Does anyone have any tips for starting this project? Thanks in advance!

  Good day! I have 2 Projects in my Eclipse. MainActivity1 and MainActivity2 are the names of the activities.

Any tips will be a great help. Thanks

• Select text in edit window using DPAD

  - by rajankz

  I am using the DPAD controls to highlight text in android text-widget. I am wondering is there is any way that when i highlight the text, it selects it also. Right now when i highlight and try to bring the context menu, the first context menu I get is the one with options to select word, select all etc. and when i do select word, it selects the entire region highlighted(which is okay , but i wanted it to select while am highlighting) so that i could get the cut/copy and paste context menu directly. Any tips? Thanks a lot.

• How can I "undelete" a set of documents in CouchDB?

  - by radicand

  I have a large set of documents in a CouchDB database that were just accidentally bulk deleted using _deleted:true. I also have a backup for this set of data that includes their last known good revision and metadata. I need to maintain the same _id, so simple restore with a new _id is not an option. Compaction has not been run and I can access any of these documents via the &rev= url parameter as well as their attachments (which are needed). What I need to do is "restore" these documents to the revision I have on file. Surprisingly, I have come up empty with any queries on how to achieve this. Tips or hacks appreciated.

• Quick C Style Question

  - by LearningC

  Which is considered better style? int set_int(int *source){ *source = 5; return 0; } int main(){ int x*; set_int(x); } OR int *set_int(){ int *temp = NULL; temp = malloc(sizeof (int)); *temp = 5; return temp; } int main(){ int *x = set_int(); } Coming for a higher level programming background I gotta say I like the second version more. Any, tips would be very helpful. Still learning C.

• read integers from a file into a vector in C++

  - by user2922063

  I am trying to read an unknown number of double values stored on separate lines from a text file into a vector called rainfall. My code won't compile; I am getting the error no match for 'operator>>' in 'inputFile >> rainfall' for the while loop line. I understand how to read in from a file into an array, but we are required to use vectors for this project and I'm not getting it. I appreciate any tips you can give on my partial code below. vector<double> rainfall; // a vector to hold rainfall data // open file ifstream inputFile("/home/shared/data4.txt"); // test file open if (inputFile) { int count = 0; // count number of items in the file // read the elements in the file into a vector while ( inputFile >> rainfall ) { rainfall.push_back(count); ++count; } // close the file
