Cannot connect Nexus One Phone to Android adb

- by appbee

I am running Android SDK 2.2 and am trying to get the adb to connect to the Google Nexus One phone. Its a new phone, shipped straight from Google - haven't installed any apps on it yet. (I have Windows XP) Here is what I have done so far: Followed the instructions on setting up the device for development as given on the Android Developer's site: http://developer.android.com/guide/developing/device.html added android:debuggable="true" to my application manifest USB debuggable is checked on the phone downloaded the Device Drivers For Windows Revision 3 (this supports Nexus One phones) Went through the Hardware Installation wizard to install the device - the device shows up as "Android Composite ADB Interface". When I run adb devices on the shell, the device appears for a moment, then disappears. On the Eclipse console, I get the following message: [2010-11-13 11:54:42 - DeviceMonitor]Failed to start monitoring I have rebooted the pc several times, uninstalled and reinstalled the drivers several times, but I get the same error each time. As I was researching this problem, someone had recommended rebooting the phone. I am a bit confused by that - is that a soft or hard reboot? Do I just power the phone off/on and is there something more complex involved? Do I have to hard reboot it to reset to factory version - even though its brand new? Has anyone run into a similar problem? Any help on this would be great. I can't test my application on the device if the adb cannot view the device. Thanks so much in advance.

Using jquery Autocomplete on textbox control in c#

- by Abid Ali

When I run this code I get alert saying Error. My Code: <script type="text/javascript"> debugger; $(document).ready(function () { SearchText(); }); function SearchText() { $(".auto").autocomplete({ source: function (request, response) { $.ajax({ type: "POST", contentType: "application/json; charset=utf-8", url: "Default.aspx/GetAutoCompleteData", data: "{'fname':'" + document.getElementById('txtCategory').value + "'}", dataType: "json", success: function (data) { response(data.d); }, error: function (result) { alert("Error"); } }); } }); } </script> [WebMethod] public static List<string> GetAutoCompleteData(string CategoryName) { List<string> result = new List<string>(); using (SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["DbConnection"].ConnectionString)) { using (SqlCommand cmd = new SqlCommand("select fname from tblreg where fname LIKE '%'+@CategoryText+'%'", con)) { con.Open(); cmd.Parameters.AddWithValue("@CategoryText", CategoryName); SqlDataReader dr = cmd.ExecuteReader(); while (dr.Read()) { result.Add(dr["fname"].ToString()); } return result; } } } I want to debug my function GetAutoCompleteData but breakpoint is not fired at all. What's wrong in this code? Please guide. I have attached screen shot above.

Use XML Layout to contain a simple drawing

- by user329999

I would like to create a simple drawing (lines, circles, squares, etc...) but I'm having difficulty figuring out the best way to do this. The drawing would need to be scaled to fit the display since the size is indirectly specified by the user (like in a CAD application). Also, I don't want to take up the entire display, leaving room for some controls (buttons, etc). I would pass the data to describe the drawing. Here's how I imagine it would work. I create an XML layout that contains something that holds the drawing (ImageView, BitmapDrawable, ShapeDrawable, ...??? not sure exactly what). Then in my Activity I would load the main XML and obtain the resource for the control that holds the drawing. I would then draw to a bitmap. Once the bitmap was completed I would load it into the control that is to hold the drawing. Somewhere along this path it would be scaled to fill the entire area allocated for the drawing in the XML layout. I don't know if my approach is the way to do this or what classes to use. I read the http://developer.android.com/guide/topics/graphics/2d-graphics.html documentation, but it's not helping me with an example. The examples I do find leave me with hints, but nothing concrete enough to do what I want, especially when it comes to scaling, using XML and/or having other controls. Also, there seems to be no good documentation on the design of the 2D drawing system in a more conceptual manner, so it makes what I read difficult to put into any useful context. Any hints on what classes would be useful and/or a good example any other reading materials? Thanks

Create a dictionary property list programmatically

- by jovany

I want to programatically create a dictionary which feeds data to my UITableView but I'm having a hard time with it. I want to create a dictionary that resembles this property list (image) give or take a couple of items. I've looked at "Property List Programming Guide: Creating Property Lists Programmatically" and I came up with a small sample of my own: //keys NSArray *Childs = [NSArray arrayWithObjects:@"testerbet", nil]; NSArray *Children = [NSArray arrayWithObjects:@"Children", nil]; NSArray *Keys = [NSArray arrayWithObjects:@"Rows", nil]; NSArray *Title = [NSArray arrayWithObjects:@"Title", nil]; //strings NSString *Titles = @"mmm training"; //dictionary NSDictionary *item1 = [NSDictionary dictionaryWithObject:Childs, Titles forKey:Children , Title]; NSDictionary *item2 = [NSDictionary dictionaryWithObject:Childs, Titles forKey:Children , Title]; NSDictionary *item3 = [NSDictionary dictionaryWithObject:Childs, Titles forKey:Children , Title]; NSArray *Rows = [NSArray arrayWithObjects: item1, item2, item3, nil]; NSDictionary *Root = [NSDictionary dictionaryWithObject:Rows forKey:Keys]; // NSDictionary *tempDict = [[NSDictionary alloc] //initWithContentsOfFile:DataPath]; NSDictionary *tempDict = [[NSDictionary alloc] initWithDictionary: Root]; I'm trying to use this data of hierachy for my table views. I'm actually using this article as an example. So I was wondering how can I can create my property list (dictionary) programmatically so that I can fill it with my own arrays. I'm still new with iPhone development so bear with me. ;)

C# Late Binding for Parameterized Property

- by optim

I'm trying to use late binding to connect to a COM automation API provided by a program called Amibroker, using a C# WinForms project. So far I've been able to connect to everything in the API except one item, which I believe to be a "parameterized property" based on extensive Googling. Here's what the API specification looks like according to the docs (Full version here: http://www.amibroker.com/guide/objects.html): Property Filter(ByVal nType As Integer, ByVal pszCategory As String) As Long [r/w] A javascript snippet to update the value looks like this: AB = new ActiveXObject("Broker.Application"); AA = AB.Analysis; AA.Filter( 0, "market" ) = 0; Using the following C# late-binding code, I can get the value of the property, but I can't for the life of me figure out how to set the value: object[] parameter = new object[2]; parameter[0] = Number; parameter[1] = Type; object filters = _analysis.GetType().InvokeMember("Filter", BindingFlags.GetProperty, null, _analysis, parameter); So far I have tried: using BindingFlags.SetProperty, BindingFlags.SetField casting the returned object to a PropertyInfo object and trying to update the value using it adding extra object containing the value to the parameters object various other things as last-ditch efforts From what I can see, this should be straight-forward, but I'm finding the late binding in C# to be cumbersome at best. The property looks like a method call to me, which is what is throwing me off. How does one assign a value to a method, and what would the prototype for late-binding C# code look like for it? Hopefully that explains it well enough, but feel free to ask if I've left anything unclear. Thanks in advance for any help! Daniel

Uploading a file fails under WordPress

- by Ash

I'm using WordPress and I'm following W3's guide for uploading a file: HTML code: <html> <body> <form action="upload_file.php" method="post" enctype="multipart/form-data"> <label for="file">Filename:</label> <input type="file" name="file" id="file" /> <br /> <input type="submit" name="submit" value="Submit" /> </form> </body> </html> PHP code (upload_file.php): <?php if ($_FILES["file"]["error"] > 0) { echo "Error: " . $_FILES["file"]["error"] . "<br />"; } else { echo "Upload: " . $_FILES["file"]["name"] . "<br />"; echo "Type: " . $_FILES["file"]["type"] . "<br />"; echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />"; echo "Stored in: " . $_FILES["file"]["tmp_name"]; } ?> The HTML code is pasted in a PHP page template and the PHP file under the WP installation directory under www. The problem is when I submit the file I get Error: 1. If I remark the "if" part of the PHP code and leave the "else" part I get: Upload: IMG_4258.JPG Type: Size: 0 Kb Stored in: So at least I know the PHP code is running. But what's causing it to fail? Is there a problem with the code or is WordPress meddling with the process?

Vim - show diff on commit in mercurial;

- by JackLeo

In my .hgrc I can provide an editor or a command to launch an editor with options on commit. I want to write a method or alias that launches $ hg ci, it would not only open up message in Vim, but also would split window and there print out $ hg diff. I know that I can give parameters to vim by using +{command} option. So launching $ vim "+vsplit" does the split but any other options goes to first opened window. So I assume i need a specific function, yet I have no experience in writing my own Vim scripts. The script should: Open new vertical split with empty buffer (with vnew possibly) In empty buffer launch :.!hg diff Set empty buffer file type as diff :set ft=diff I've written such function: function! HgCiDiff() vnew :.!hg diff set ft=diff endfunction And in .hgrc I've added option: editor = vim "+HgCiDiff()" It kind of works, but I would like that splited window would be in right side (now it opens up in left) and mercurial message would be focused window. Also :wq could be setted as temporary shortcut to :wq<CR>:q! (having an assumption that mercurial message is is focused). Any suggestions to make this a bit more useful and less chunky? UPDATE: I found vim split guide so changing vnew with rightbelow vnew opens up diff on the right side.

Binding KeyUp event to Input Field

- by user306686

I am dynamically generating textboxes in ruby using <%0.upto(4) do |i| % <%= text_field_tag('relative_factor[]', @prefill_values[:relative_factor][i],:size = 6,:maxlength = 5) % <%end% it generates following HTML markup Another set of textboxes: <%0.upto(4) do |i| % <%= text_field_tag('rating_factor[]', @prefill_values[:relative_factor][i],:size = 6,:maxlength = 5) % <%end% it generates following HTML markup I have one more textbox: ..... I want to update id="rating_factor_" textboxes as the value in either id="multiple" textbox changes or id="relative_factor_" textboxes changes. E.g. id="multiple" textbox = 5 id="relative_factor_" value= 0.0 textbox = 1 id="relative_factor_" value= 1.0 textbox = 2 id="relative_factor_" value= 2.0 textbox = 3 id="relative_factor_" value= 3.0 textbox = 4 id="relative_factor_" value= 4.0 textbox = 5 I want to show (multiple multiple and relative_factor_ and show) id="rating_factor_" value= 0.0 textbox = 5 id="rating_factor_" value= 1.0 textbox = 10 id="rating_factor_" value= 2.0 textbox = 15 id="rating_factor_" value= 3.0 textbox = 20 id="rating_factor_" value= 4.0 textbox = 25 Now if user changes, id="relative_factor_" value= 1.0 textbox as 1.5 then id="rating_factor_" value= 1.0 textbox should be updated as 7.5 To achieve above goal, I tried binding #relative_factor_ to keyup event but as id is same for all i.e.#relative_factor_, it returns value for first textbox i.e. id="relative_factor_" value= 0.0. Please guide me to crack this problem. Thanks in Advance.

NUnit integration programmatically with spring

- by harkon

Hi! I have a component based architecture framework designed and I use NUnit for isolated testing - okay so far. Now I want to enable integration tests. Therefore the tests use real implementations of the existing components. Each element of the component has a life cycle (init, start and stop) and I created a NUnit component. In the start section the Console runner of the NUnit will be executed. Okay - now if I have a test fixture class in my dlls in the execution path the runner exectues them - fine! But: And this is crucial! Each to be tested implementation exists so far in the process and I want to use this instances for testing. If I use NUnit runner in the current way each instance will be created twice - and above all: I have a spring container and a implementation registry. Via this registry I can get access to all instances in the processes. But how do I give the test fixture access to the existing registry? Good: I can start the component architecture framework in the startup of the nunit runner - but this is not what I want. My guide is the apache Cactus framework (with JUnit and tomcat, JBoss etc.) Can someone help? Thanks a lot! Check: http://cone.codeplex.com

Can Content script set value of a text box within HTML frame? using Google Chrome extensions..

- by devdreamers

Hi all, I was working on a very simple extension, where on clicking extension icon, a webpage is opened in a new tab, the webpage has HTML frames, within which lies a textbox. I want to set a value for the same. The webpage which opens has: <HTML> <FRAMESET rows="15%, *" border="0"> <FRAME src="./files/abc.htm" id="abc_frame" name="abc_frame" onload="abcLoad()" scrolling="NO"> </FRAMESET> </HTML> and abc.htm has: <div align="center" valign="bottom" style="font-size: 1em;"> <form onSubmit="javascript:navigate(this);return false;"> <label for="loc">Loc</label>: <input type="text" size="50" id="loc" value="http://google.com"/> <input name="go" type="submit" value="Go" id="loc_go" onclick='navigate(this); return false;'/> </form> </div> how can I replace current textbox value with, say http://yahoo.com ? I guess, Content Script in Chrome extensions is required, but not sure, how/what should be it's code/content. Please guide/help. Thanks a lot. Appreciate it.

Extract domain from body of email

Hi, I was wondering if there is any way I could extract domain names from the body of email messages in python.

Script to install and compile Python, Django, Virtualenv, Mercurial, Git, LessCSS, etc... on Dreamho

- by tmslnz

The Story After cleaning up my Dreamhost shared server's home folder from all the cruft accumulated over time, I decided to start afresh and compile/reinstall Python. All tutorials and snippets I found seemed overly simplistic, assuming (or ignoring) a bunch of dependencies needed by Python to compile all modules correctly. So, starting from http://andrew.io/weblog/2010/02/installing-python-2-6-virtualenv-and-virtualenvwrapper-on-dreamhost/ (so far the best guide I found), I decided to write a set-and-forget Bash script to automate this painful process, including along the way a bunch of other things I am planning to use. The Script I am hosting the script on http://bitbucket.org/tmslnz/python-dreamhost-batch/src/ The TODOs So far it runs fine, and does all it needs to do in about 900 seconds, giving me at the end of the process a fully functional Python / Mercurial / etc... setup without even needing to log out and back in. I though this might be of use for others too, but there are a few things that I think it's missing and I am not quite sure how to go for it, what's the best way to do it, or if this just doesn't make any sense at all. Check for errors and break Check for minor version bumps of the packages and give warnings Check for known dependencies Use arguments to install only some of the packages instead of commenting out lines Organise the code in a manner that's easy to update Optionally make the installers and compiling silent, with error logging to file failproof .bashrc modification to prevent breaking ssh logins and having to log back via FTP to fix it EDIT: The implied question is: can anyone, more bashful than me, offer general advice on the worthiness of the above points or highlight any problems they see with this approach? (see my answer to Ry4an's comment below) The Gist I am no UNIX or Bash or compiler expert, and this has been built iteratively, by trial and error. It is somehow going towards apt-get (well, 1% of it...), but since Dreamhost and others obviously cannot give root access on shared servers, this looks to me like a potentially very useful workaround; particularly so with some community work involved.

Indexing community images for google image search

- by Vittorio Vittori

Hi, I'm trying to understand how can I do to let my site be reachable from google image search spiders. I like how last.fm solution, and I thought to use a technique like his staff do to let google find artists images on their pages. When I'm looking for an artist and I search it on google image search, as often as not I find an image from last.fm artists page, I make an example: If I search the band Pure Reason Revolution It brings me here, the artist's image page http://www.last.fm/music/Pure+Reason+Revolution/+images/4284073 Now if I take a look to the image file, i can see it's named: http://userserve-ak.last.fm/serve/500/4284073/Pure+Reason+Revolution+4.jpg so if I try to undertand how the service works I can try to say: http://userserve-ak.last.fm/serve/ the server who serve the images 500/ the selected size for the image 4284073/ the image id for database Pure+Reason+Revolution+4.jpg the image name I thought it's difficult to think the real filename for the image is Pure+Reason+Revolution+4.jpg for image overwrite problems when an user upload it, in fact if I digit: http://userserve-ak.last.fm/serve/500/4284073.jpg I probably find the real image location and filename With this tecnique the image is highly reachable from search engines and easily archived. My question is, does exist some guide or tutorial to approach on this kind of tecniques, or something similar?

How do you parse the XDG/gnome/kde menu/desktop item structure in c++??

- by Joe Soul-bringer

I would like to parse the menu structure for Gnome Panels (the standard Gnome Desktop application launcher) and it's KDE equivalent using c/c++ function calls. That is, I'd like a list of what the base menu categories and submenu are installed in a given machine. I would like to do with using fairly simple c/c++ function calls (with NO shelling out please). I understand that these menus are in the standard xdg format. I understand that this menu structure is stored in xml files such as: /home/user/.config/menus/applications.menu I've look here: http://www.freedesktop.org/wiki/Specifications/menu-spec?action=show&redirect=Standards%2Fmenu-spec but all they offer is the standard and some shell files to insert item entries (I don't want shell scripts, I don't want installation, I definitely don't want to create a c-library from the XDG specification. I want to find the existing menu structure). I've looked here: http://library.gnome.org/admin/system-admin-guide/stable/menustructure-13.html.en for more notes on these structures. None of this gives me a good idea of how determine the menu structures using a c/c++ program. The actual gnome menu structures seem to be a horrifically hairy things - they don't seem to show the menu structure but to give an XML-coded description of all the changes that the menus have gone through since installation. I assume gnome panels parses these file so there's a function buried somewhere to do this but I've yet to find where that function is after scanning library.gnome.org for a couple of days. I've scanned the Nautilus source code as well but Panels seem to exist elsewhere or are burried well. Thanks in advance

Declaration, allocation and assignment of an array of pointers to function pointers

- by manneorama

Hello Stack Overflow! This is my first post, so please be gentle. I've been playing around with C from time to time in the past. Now I've gotten to the point where I've started a real project (a 2D graphics engine using SDL, but that's irrelevant for the question), to be able to say that I have some real C experience. Yesterday, while working on the event system, I ran into a problem which I couldn't solve. There's this typedef, //the void parameter is really an SDL_Event*. //but that is irrelevant for this question. typedef void (*event_callback)(void); which specifies the signature of a function to be called on engine events. I want to be able to support multiple event_callbacks, so an array of these callbacks would be an idea, but do not want to limit the amount of callbacks, so I need some sort of dynamic allocation. This is where the problem arose. My first attempt went like this: //initial size of callback vector static const int initial_vecsize = 32; //our event callback vector static event_callback* vec = 0; //size static unsigned int vecsize = 0; void register_event_callback(event_callback func) { if (!vec) __engine_allocate_vec(vec); vec[vecsize++] = func; //error here! } static void __engine_allocate_vec(engine_callback* vec) { vec = (engine_callback*) malloc(sizeof(engine_callback*) * initial_vecsize); } First of all, I have omitted some error checking as well as the code that reallocates the callback vector when the number of callbacks exceed the vector size. However, when I run this code, the program crashes as described in the code. I'm guessing segmentation fault but I can't be sure since no output is given. I'm also guessing that the error comes from a somewhat flawed understanding on how to declare and allocate an array of pointers to function pointers. Please Stack Overflow, guide me.

Is this a hole in dynamic binding in C# 4?

- by Galilyou

I've seen a very interesting post on Fabio Maulo's blog. Here's the code and the bug if you don't want to jump to the url. I defined a new generic class like so: public class TableStorageInitializer<TTableEntity> where TTableEntity : class, new() { public void Initialize() { InitializeInstance(new TTableEntity()); } public void InitializeInstance(dynamic entity) { entity.PartitionKey = Guid.NewGuid().ToString(); entity.RowKey = Guid.NewGuid().ToString(); } } Note that InitializeInstance accepts one parameter, which is of type dynamic. Now to test this class, I defined another class that is nested inside my main Program class like so: class Program { static void Main(string[] args) { TableStorageInitializer<MyClass> x = new TableStorageInitializer<MyClass>(); x.Initialize(); } private class MyClass { public string PartitionKey { get; set; } public string RowKey { get; set; } public DateTime Timestamp { get; set; } } } Note: the inner class "MyClass" is declared private. Now if i run this code I get a "Microsoft.CSharp.RuntimeBinder.RuntimeBinderException" on the line "entity.PartitionKey = Guide.NewGuid().ToString()". The interesting part, though is that the message of the exception says "Object doesn't contain a definition for PartitionKey". Also note that if you changed the modifier of the nested class to public, the code will execute with no problems. So what do you guys think is really happening under the hood? Please refer to any documentation -of course if this is documented anywhere- that you may find?

Implementation of delegates in C#

- by Ram

Hi, I am trying to learn on how to use delegates efficiently in C# and I was just wondering if anyone can guide me through... The following is a sample implementation using delegates... All I am doing is just passing a value through a delegate from one class to another... Please tell me if this is the right way to implement... And also your suggestions... Also, please note that I have de-registered the delegate in : void FrmSample_FormClosing(object sender, FormClosingEventArgs e) { sampleObj.AssignValue -= new Sample.AssignValueDelegate(AssignValue); } Is this de-registration necessary? The following is the code that I have written.. public partial class FrmSample : Form { Sample sampleObj; public FrmSample() { InitializeComponent(); this.Load += new EventHandler(FrmSample_Load); this.FormClosing += new FormClosingEventHandler(FrmSample_FormClosing); sampleObj = new Sample(); sampleObj.AssignValue = new Sample.AssignValueDelegate(AssignValue); } void FrmSample_FormClosing(object sender, FormClosingEventArgs e) { sampleObj.AssignValue -= new Sample.AssignValueDelegate(AssignValue); } void FrmSample_Load(object sender, EventArgs e) { sampleObj.LoadValue(); } void AssignValue(string value) { MessageBox.Show(value); } } class Sample { public delegate void AssignValueDelegate(string value); public AssignValueDelegate AssignValue; internal void LoadValue() { if (AssignValue != null) { AssignValue("This is a test message"); } } } Pls provide your feedback on whether this is right... Thanks, Ram

Pump Messages During Long Operations + C# (it is urgent)

- by Newbie

Hi I have a web service that is doing huge computation and is taking more than a minute. I have generated the proxy file of the web service and then from my client end I am using the dll(of course I generated the proxy dll). My client side code is TimeSeries3D t = new TimeSeries3D(); int portfolioId = 4387919; string[] str = new string[2]; str[0] = "MKT_CAP"; DateRange dr = new DateRange(); dr.mStartDate = DateTime.Today; dr.mEndDate = DateTime.Today; Service1 sc = new Service1(); t = sc.GetAttributesForPortfolio(portfolioId, true, str, dr); But since it is taking to much time for the server to compute, after 1 minute I am receiving an error message The CLR has been unable to transition from COM context 0x33caf30 to COM context 0x33cb0a0 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations. Kindly guide me what to do? It is very urgent. Thanks

What is your favorite API developer community site? And why? [closed]

- by whatupwilly

There are a lot of great sites out there that offer good documentation, tools, tips, best-practices, sample code, etc. for the API's they are publishing. A sample: http://apiwiki.twitter.com http://developer.netflix.com/ http://developers.facebook.com/ https://affiliate-program.amazon.com/gp/advertising/api/detail/main.html http://code.google.com/ http://remix.bestbuy.com/ http://www.flickr.com/services/api/misc.overview.html http://products.wolframalpha.com/api/webserviceapi.html There are some no-brainers that I think a good developer site should have: Hi level introduction Quick start guide API specific details - showing example request and responses Links to sample code and/or 3rd party libraries Developer registration (e.g. get an API key) Blog But what about some other things: Online-Forum or Msg Board vs. Google Group (or similar) Galleries/ShowCases - spotlighting great apps built on the API - who has done nice galleries? Community Wiki - How do people feel about letting the community have edit rights on API documentation pages Online testing tools (like Facebook has a lot of nice interactive tools to simulate request/responses) What are some packages that you would recommend to put this all together: pbwiki Google Group pages MediaWiki API vendor package such as Sonoa Systems that offers a customizable developer portal So, to summarize: What are some other great API developer portals out there What are some nice features you like on them Any recommendations on what to use to build these features out Thanks, Will Zappos.com Public API (soon to launch) Product Manager

My chance to shape our development process/policy

- by Matt Luongo

Hey guys, I'm sorry if this is a duplicate, but the question search terms are pretty generic. I work at a small(ish) development firm. I say small, but the company is actually a fair size; however, I'm only the second full-time developer, as most past work has been organized around contractors. I'm in a position to define internal project process and policy- obvious stuff like SCM and unit-testing. Methodology is outside the scope of the document I'm putting together, but I'd really like to push us in a leaner (and maybe even Agile?) direction. I feel like I have plenty of good practice recommendations, but not enough solid motivation to make my document the spirit guide I'd like it to be. I've separated the document into "principles" and "recommendations". Recommendations have been easy to come up with. Use SCM, strive for 1-step, regularly scheduled builds, unit test first, document as you go... Listing the principles that are supposed to be informing these recommendations, though, has been rough. I've come up with "tools work for us; we should never work for tools" and a hazy clause aimed at our QA (which has been overly manual) that I'd like to read "tedium is the root of all evil". I don't want to miss an opportunity with this document to give us a good in-house start and maybe even push us toward Agile. What principles am I missing?

How to mark multiple coordinates in KML using Java?

- by Akshay

I'm working on a project that involves KML creation using Java. Currently, I'm fooling with the sample Java code from the KML example at Micromata Labs JAK Example. I tried to "extend" the code by adding multiple coordinates and getting two markers, but I could not get it to work. Can you please tell me how I can add multiple coordinates and put markers on them, and also, draw a line between the markers. Thank you for your help! PS: I need to do this via the program. I saw sample code of them using DOM and XML, but not pure Java/JAK as such. Please guide me. I got as far as this: kml .createAndSetDocument().withName("My Markers"). createAndAddPlacemark().withName("London, UK").withOpen(Boolean.TRUE) .createAndSetPoint().addToCoordinates(-0.126236, 51.500152); kml.createAndSetPlacemark() .withName("Somewhere near London, UK").withOpen(Boolean.TRUE) .createAndSetPoint().addToCoordinates(-0.129800,52.700152); But I know I'm going wrong somewhere. Please point me in the right direction.

How to install Zend Framework on Windows

- by sombe

"installing Zend Framework is so easy!!!!" yeah right... Ok I'm working with a beginner's book and the ONE thing that is not excessively detailed is the most important part: Installing the darn thing. After browsing the quickstart guide for hours, all it said was: "download Zend [...] add the include directory (bla bla) and YOU'RE DONE!" right, i'm done using Zend. Ok, not really, not yet anyway. I beg of you people, I wanna go to bed, please tell me how (in simple 6th grade detail) to install the framework. I've got the unzipped folder in my htdocs directory, and I placed zf.bat+zf.php in the htdocs root. What's next? thank you so much. EDIT: Thanks guys for all the answers. Unfortunately I haven't been able to work with this or find a good enough resource to explain it to me in plain english. It seems that this framework adheres more so to programmers than to beginners. I've since yesterday read a little on CakePHP and found that it was incredibly easy to install and tune. As oppose to Zend Framework, where I had to dig in my "environment variables", configure "httpd.conf" and almost tie the knot between my computer driver cables to just get it running, CakePHP has already allowed me to put together a nice newbie application. In conclusion, I very much appreciate all of your help. I hope someone else venturing on ZF will be more successful with it. Thanks!

jboss cache as hibernate 2nd level - cluster node doesn't persist replicated data

- by Sergey Grashchenko

I'm trying to build an architecture basically described in user guide http://www.jboss.org/file-access/default/members/jbosscache/freezone/docs/3.2.1.GA/userguide_en/html/cache_loaders.html#d0e3090 (Replicated caches with each cache having its own store.) but having jboss cache configured as hibernate second level cache. I've read manual for several days and played with the settings but could not achieve the result - the data in memory (jboss cache) gets replicated across the hosts, but it's not persisted in the datasource/database of the target (not original) cluster host. I had a hope that a node might become persistent at eviction, so I've got a cache listener and attached it to @NoveEvicted event. I found that though I could adjust eviction policy to fully control it, no any persistence takes place. Then I had a though that I could try to modify CacheLoader to set "passivate" to true, but I found that in my case (hibernate 2nd level cache) I don't have a way to access a loader. I wonder if replicated data persistence is possible at all by configuration tuning ? If not, will it work for me to create some manual peristence in CacheListener (I could check whether the eviction event is local, and if not - persist it to hibernate datasource somehow) ? I've used mvcc-entity configuration with the modification of cacheMode - set to REPL_ASYNC. I've also played with the eviction policy configuration. Last thing to mention is that I've tested entty persistence and replication in project that has been generated with Seam. I guess it's not important though.

Does the "Supporting Multiple Screens" document contradict itself?

- by Neil Traft

In the Supporting Multiple Screens document in the Android Dev Guide, some example screen configurations are given. One of them states that the small-ldpi designation is given to QVGA (240x320) screens with a physical size of 2.6"-3.0". According to this DPI calculator, a 2.8" QVGA display equates to 143 dpi. However, further down the page the document explicitly states that all screens over 140 dpi are considered "medium" density. So which is it, ldpi or mdpi? Is this a mistake? Does anyone know what the HTC Tattoo or similar device actually reports? I don't have access to any devices like this. Also, with the recent publishing of this document, I'm glad to see we finally have an explicit statement of the exact DPI ranges of the three density categories. But why haven't we been given the same for the small, medium, and large screen size categories? I'd like to know the exact ranges for all these. Thanks in advance for your help!
