Dash search in Ubuntu / Unity

When I first upgraded to Ubuntu 11.04 I took an instant disliking to its new desktop environment - Unity. But sadly I was really out of choice as GNOME 3 was even more disappointing (they even decided to do way with minimize and maximize buttons). Unity in Ubuntu 11.10 was a bit improved but still I hated the interface. But now, I have kind of got used to it and discovered this new thing in Dash search.

In Unity you can search for applications in Dash, but what I didn't know that you could also search inside applications. Basically I wanted to change the theme so I went to Dash and searched for "theme" and look what it gave me in results.

Declaring global variable in XPage using dataContexts

While working on a XPages application I required a database object to be initialized and then used in various controls in XPage. I wanted to initialize the object only once then use it again and again. With some experimenting I found out that if I put the initialization code in beforePageLoad, afterPageLoad or beforeRenderResponse I was able to access the object from anywhere in XPage. But I wasn't sure that whether this was the correct way or the objects would get automatically garbage collected. So I posted this question on XPages forum.

Paul S. Withers suggested me to use dataContexts. You can find them in All Properties tab of XPages properties inside data section.

Getting methods, fields, constructors for XPage Java classes


In my previous blog I was able to find out which Java classes were represented by global objects & functions of SSJS. For e.g. facesContext.getExternalContext() returns object of com.ibm.xsp.domino.context.DominoExternalContext. But what methods, fields, etc. are available in that class? To get those you use the Reflection API (java.lang.reflect package) in Java via which we can find out the methods, fields, etc in a class. Using this I built a small XPage which can explore these classes. Here’s how it looks:

Double exclamation / bang (!!) in Lotus Notes

Double bang or double exclamation (!!) is an interesting thing in Lotus Notes. It basically is an internal network separator to Notes1 used to separate the server name and database path. No wonder in older release of Lotus Notes, launching attachments which have double exclamation marks in file name would crash Notes client. Also if you try to attach a file (either from Notes client, web or XPages) with double exclamation marks in its name, then the part preceding the double exclamation marks is removed from the attached file name. So if your name of file is file!!name.txt then after attaching, your file name would be name.txt. Even using the EmbedObject method in NotesRichTextItem class attaches the file in same way.

I used it myself when I wanted to open a specific frameset in a different database. Basically where ever you find the @ button in properties, there you can specify the server & database concatenated with double exclamation marks.


Also you use it in Show Database command at the Domino server console to display database and view information on a different server. David Leedy found out that while binding XPages to external databases you need to use double exclamation. Even in the C API function of W32_NSFDbOpen(dbpath$, hdb&) you specify the dbpath$ as <Server>!!<Database path>.

Update 8 Jan 2012: Starting with Notes and Domino 8.5.3 you can set up Domino to preload XPage applications using the notes.ini entry of XPagesPreloadDB, where you specify the server and database name concatenated with double exclamation. And yes, it is present in the final release of the 8.5.3.

The need for a different Marketplace

My grandmother always said that in the first day of a new year you should do what you would like to do the rest of the year. Even if the last year I didn't had a lot of time to blog I always wanted to so here I am wanting to start the year with my blog.
So what is wrong with the current version of the Marketplace? I could say nothing really, but there is so much that could be improved/changed. I am referring here to the marketplace of all major mobile platforms: Android, iOS and Windows Phone. They are more or less the same. Right now I have experience as a developer with Windows Phone marketplace and as a customer/consumer with all three of them. The marketplace was/is one of the greatest marketing/selling instrument in the software industry. In theory it gives the opportunity to everyone to sell their ideas/software all over the world. I say in theory because it enables developers to do that, but it doesn't make it easy.
One of the biggest problems I see for the moment is the number of applications. I am looking at the Microsoft "race" to catch up with the number of applications in the marketplace. In this race the number is the priority and the quality comes second. The result of this race is that the marketplace get filled with "junk". It is the same situation on all the three platforms, but today the analysts judge the success of a platform by the number of apps in the marketplace. Let's face it there are 500.000 application in the Apple marketplace and, maybe, not even 10% are quality apps. When I say junk I say applications that don't bring any innovation, written as fast as possible and thrown into the wild just to have an application out there. From my experience (I have a small application in the marketplace) in order to have a decent application there is a lot of work to be done in developing and maintaining it. Having so many applications in the marketplace "kills" the opportunity marketplace gives you if you have a quality app because it makes it almost invisible. If today you have a quality app and you publish it will be there with (I will take the Windows Phone marketplace numbers published by http://wp7applist.com/en-US/stats/ today 01.01.2012) other 451 applications published the same day. Does you application stand any chance? Some will say yes, I would say the more apps are in the marketplace the harder will be. You can only count on the people that are trying new applications. So inevitable a quality app will go down (maybe a little bit slower ) with the others and you have to find other methods to get it "visible". Another consequence of having a lot of applications published every day without a quality check is the degrade in the service offered to developers. I remember that when I wrote this post: http://sviluppomobile.blogspot.com/2011/01/windows-phone-marketplace-more.html the quality of certification the service was great. Things changed a little in the last two months (I think they had an increase in the number of applications to certify) the certification time jumped from two days to more than a week. More frustrating is seeing applications like this one published in "bulk":


So is it worth having thousands of applications without any quality filter (just rules on how to write your app)? I would prefer a quality marketplace, but maybe having both is better. It's like when you go to the market to shop: if you want products that cost less you go in one place, if you want quality products you go to another shop, if you just need one product you go in the first shop you find. The marketplace in the marketplace could improve a little bit on the quality part. It would need quality reviewers that would select the apps for the "quality" marketplace. It is easier than to go on all review websites and look for top applications on each platform. A place in the marketplace where you go when you don't know what you really want but you would like to try some quality applications. Apple, Google and Microsoft should not be the quality reviewers but continue to do what they do and then the best reviewers/websites on each platform should intersect their chosen applications (easy to say and hard to do). It is not a bullet proof mechanism.
Other suggestion regards the reviews specifically bad reviews. In this moment if you want to make a concurrent application go down you just go and slowly start to make bad reviews in all the marketplaces. (it is a situation I am dealing with). I would suggest that, if someone makes a bad review and give one or two stars, he should be "forced" to write a reason. This should help the developers understand the problem, and, if it's not true at least ask the review to be removed. Also the reviews should be disabled when the application is hidden. For the hidden applications the reviews don't make any sense.
Being able to publish a beta version of the application in the marketplace is an awesome feature, but in this moment, for me is almost useless. You have to find your beta testers, but it is a difficult task. So there should be an "open" beta option. This way anybody that wants to test the beta and has a link to it can do it with a limit of 100 users (more or less like the hidden apps but limited to a number of users).
In my opinion 2011 was a great year for Windows Phone even if the market shares don't reflect it . The 7.5 version is a great step forward and I hope that 2012 will bring us another big step. I still think that the application list is "ugly" and not really usable, we need some way to group applications (maybe an evolution of the "folder" concept).
I really hope Microsoft will make Apollo an EVOLUTION and not a REVOLUTION.

Happy New Year to all my readers! A better year to everyone.

Import image resources via LotusScript & Java

People have created various versions where you can import image resources in a NSF database using LotusScript. Basically you mimic the functionality of "Import Image Resource" button present in Domino Designer via code.


Some of the examples can be found here and here. Here is my version of doing this same thing using combination of LotusSciript & Java with LS2J.

"loaded" vs "rendered" in XPages

I couldn’t find many resources on the exact difference between loaded and rendered property available in XPage controls except for this blog by Thiyagarajan.

When you hover your mouse over loaded property it says – “Specifies whether or not the control should be created when the page is loaded.” while for rendered it says – “Indicates whether or not control should be displayed or processed on any subsequent form submission.”. Enabling the properties (exclusively) does not generate the control in the web page. But this is where the similarity ends. It was after a discussion with Sven Hasselbach on XPages forum, I understood the usage of these properties.

Create two computed fields cfLoaded and cfRendered with loaded & rendered property set to false in them respectively. Now add another computed field with following code:

Accessing XPages global objects in Java

Update 24-Dec-2011: Added method to access session and database.

Update 10-Mar-2012: Updated the view object as it was pointing to a super class. Thanks to Tom pointing that one out.

Update 22-May-2012: Rectified the code to get viewScope. Thanks to Jens Winkelmann for pointing it out.

Update 16-Mar-2013: Added link to get getComponent equivalent in Java.

Tim Tripcony in his reply to one of the questions in the Notes/Domino XPages development forum had suggested using Java over SSJS to improve XPages performance. He basically said – “...Minimize the use of SSJS (server-side JavaScript). Every time any SSJS expression is evaluated, Domino parses the expression in realtime into an abstract syntax tree, then runs Java code that is a rough approximation of how the JavaScript specification states that code matching the detected syntax should run. The more you move your logic directly into true Java classes, the less expensive it is to execute, so it runs faster...

So I started thinking about how can we access various XPages Global Objects like – facesContext, sessionScope, context, etc. from Java classes.


Well... here's how we can access it:

Importing script library in Domino Designer

Domino Designer provides facility to import image resources, style sheets and file resources.


But for script libraries, there is no such option.


So when I need to import a third-party JavaScript script library I usually would create one and then copy-paste the contents into it. But there's an easier way to do it.

Where are the breakpoints stored?

I am sure at some point or another you would have used breakpoints while debugging your LotusScript code. But I always wondered how does Lotus Notes store them. Well, it stores in the profile documents. To view the profile documents in your database there free utilities available like - NotesPeek (my favorite), ProfileMgr by Andre Guirard or NoteMan.

Using NotesPeek you can see a profile document named "breakpoints_" which stores all the breakpoints.

Get Java class names for variables defined in SSJS in XPages


Every global object or variable in SSJS is an object of a class defined in Java. The help documentation says that facesContext is an object of class com.ibm.xsp.domino.context.DominoFacesContext. But what about facesContext.getExternalContext() and other variables?

Well in Java every class inherits directly or indirectly from its base class java.lang.Object. This class has a method named getClass() which returns object of class java.lang.Class (Yes, there is a class called "Class" in Java!). With this you can find out to which class the object belongs, its methods, super class and lot more.

Create a new XPage and add a computed field. Add the code given below for its value and preview it in browser.

On a dark foggy night...


This story was was emailed to me by my friend during the appraisal season... Make sure you read it till the end!

On a dark foggy night, a small figure lay huddled on the railway tracks leading to the Chennai station. At once I was held back to see someone in that position during mid night with no one around. With curiosity taking the front seat, I went near the body and tried to investigate it.

There was blood all over the body which was lying face down. It seemed ruthless blow by the last train could have caused the end of this body which seemed to be that of a guy around my age. Amidst the gory of blood flow, I could see a folded envelope which was fluttering in the midnight wind.

Carefully I took the blood stained envelope and was surprised to see the phrase “Appraisal Letter” written on it. With curiosity rising every moment, I wasted no time in opening the envelope to see if I can find some details about the dead guy. The tag around his body’s neck and the jazzy appraisal cover gave me the hint that he might be a software engineer. I opened the envelope to find a shining paper on which the appraisal details were typed in flying colours.

Thunder broke into my ears and lightning broke into my heart when I saw the appraisal amount of the dead guy! My God, it was not even, as much as the cost of the letter on which the appraisal details were printed...  My heart poured out for the guy and huge calls were heard inside my mind saying, “No wonder, this guy died such a miserable death”... As a fellow worker in the same industry, I thought I should mourn for him for the sake of respect and stood there with a heavy heart thinking of the shock he would have experienced when the manager had placed the appraisal letter in his hand. I am sure his heart would have stopped and eyes would have gone blank for a few seconds looking at the near to nothing increment in his salary.

While I mourned for him, for a second my hands froze to see the employee’s name in the appraisal letter... hey, what a strange coincidence, this guy’s name same as mine, including the initials. This was interesting. With some mental strength, I turned the body upside down and found myself fainted for a second. The guy not only had my name, but also looked exactly like me.  Same looks, same built, same name... it was me who was dead there!

While I was lost in that shock, I felt someone patting on my shoulders. My heart stopped completely, I could not breathe and sprung in fear to see who was behind... SPLASH! Went the glass of water on my laptop screen as I came out of my wild dream to see my manager standing behind patting on my shoulder saying, “Wake up man? Come to meeting number two. I have your appraisal letter ready!”

Google + Snaptu = Trouble + Confusion


Recently I discovered a beautiful mobile app called Snaptu. It enables users to access variety of services from a single screen like - Facebook, Twitter, News, etc.

There is a very good application for Google Calendar which allows you to add / modify you calendar events. This is actually much better than the Google Calendar for mobile with ability to add events specifying date / time.

But after some days when I accessed my Gmail from browser I got a message that my account was recently accessed from UK....!!!!



A bit worried, I used an IP Address Locator and found that the IP indeed belonged to UK to some website called RackSpace which is basically used for hosting services on web. Now I Googled for "Snaptu RackSpace" and got this link. It basically says that Snaptu is hosted on RackSpace. PHEW! :)

Creating ticker using JavaScript inside Lotus Notes client

I always felt that the power of JavaScript is Lotus Notes client is underrated. Some articles which do describe this are here and here. I realized this power when a some time back I had create a ticker that worked in Lotus Notes client. You can simply embed an Java applet in the form but, Java applet and Lotus Notes don't gel together very well. You also go for animated table, but then you there would be only specified number of entries (rows) which you be able to cycle through.

Using JavaScript to create a ticker is very similar to creating one for Web browser. To start off create two computed fields on your form - TickerURL & TickerText with their respective field names in their value.


Put an action hotspot around the field TickerText and write the following formula:

Opening design elements with single click in Domino Designer on Eclipse


With Domino Designer on Eclipse one change IBM made was that you needed to double click on the design elements to open them. Very irritating for a Lotus Notes developer who has been developing applications in Lotus Notes 7 or before for quite some time. But thankfully IBM provided an option in the preferences to get the previous behavior.

Open your Domino Designer on Eclipse and go to "File > Preferences". In the “General” section you see option of “Open Mode” where you can select either “Double click” or “Single click”. Select "Single click". Use the image below for reference.


And good old days are back again… :)

Editable field which does not get saved in document when saved


Ever wondered whether an editable field can be created on a form which does not get saved when the document is saved! Well it can be done. It’s pretty simple. All you need to do is to write @DeleteField in the "Input Translation" formula of the editable field in the form.


You can have an elaborate formula written in Input Translation based on which you can decide whether to save the field in document or not.

Validating number fields in Lotus Notes

Anyone who has created number field on form and done validations on that will have faced this problem.

Suppose you have a number field on a form and user enters a value other than number in it and the form gets refreshed, either by F9 (CTRL+F9 in 8.5.x) or via code to validate other fields, then Lotus Notes comes up with a beautiful error of "Cannot convert text to a number".

You don't want this message to come when you want to execute your own custom code to display error messages and show it to user. To get around this error just

User preferences deleted in Lotus Notes 7

Recently on one my colleagues Lotus Notes whenever we went to "File > Preferences > User Preferences..." a dialog box used to show up saying "Document has been deleted".

After searching on Google I found this technote which indicated that if the user is assigned some policy and it has been deleted then this problem may occur and we had policies assigned to users. But technote is talking about problem on server. But still we decided to give it a try. And it worked!
  1. Open "names.nsf" on your local machine.
  2. Go to the hidden view "($Policies)".
  3. Press "SHIFT+F9" to rebuild current view (you must have Manager access on names.nsf). And you are done!

    Open frameset of another database in Lotus Notes


    While working on a Lotus Notes client-based application I came across one peculiar scenario that we could not open a frameset residing in another database. You can code @Command([OpenFrameset]; FramesetName) in formula language or Call NotesUIWorkspace.OpenFrameSet(<FramesetName>) in LotusScript. But both these commands open frameset which reside in the same database from which the command is being executed. After searching (read it as Googling) I found a solution by Tammie Miller on SearchDomino. But this required me to modify the target database also. After some tinkering in Lotus Notes I was finally able to do it without modifying the target database.

    The Tortoise and the Hare

    A long time back my friend sent me an e-mail based on Aesop's famed fable The Tortoise and the Hare which I found pretty interesting. Its a bit long but worth reading. Here it goes...

    The Old Story

    Once upon a time a tortoise and a hare had an argument about who was faster. They decided to settle the argument with a race. They agreed on a route and started off the race.

    The hare shot ahead and ran briskly for some time. Then seeing that he was far ahead of the tortoise, he thought he`d sit under a tree for some time and relax before continuing the race.

    He sat under the tree and soon fell asleep. The tortoise plodding on overtook him and soon finished the race, emerging as the undisputed champ.

    The hare woke up and realized that he`d lost the race.

    The moral of the story is that "Slow and Steady wins the race".

    That`s the story which we grew up with!

    Here`s the contemporary version of the story and the saga of the race between the Hare and Tortoise continues.. Read on...

    The New Story

    The hare was disappointed at losing the race and he did some Defect Prevention (Root Cause Analysis). He realized that he`d lost the race only because he had been overconfident, careless and lax.

    If he had not taken things for granted, there`s no way the tortoise could have beaten him. So he challenged the tortoise to another race. The tortoise agreed.

    This time, the hare went all out and ran without stopping from start to finish. He won by several miles.

    The moral of the story : Fast and consistent will always beat the slow and steady.

    If you have two people in your organisation, one slow, methodical and reliable, and the other fast and still reliable at what he does, the fast and reliable chap will consistently climb the organisational ladder faster than the slow, methodical chap.

    It`s good to be slow and steady; but it`s better to be fast and reliable.

    But the story doesn`t end here.

    The tortoise did some thinking this time, and realised that there`s no way he can beat the hare in a race the way it was currently formatted. He thought for a while, and then challenged the hare to another race, but on a slightly different route.

    The hare agreed. They started off. In keeping with his self-made commitment to be consistently fast, the hare took off and ran at top speed until he came to a broad river.

    The finishing line was a couple of kilometers on the other side of the river.

    The hare sat there wondering what to do. In the meantime the tortoise trundled along, got into the river, swam to the opposite bank, continued walking and finished the race.

    The moral of the story? First identify your core competency and then change the playing field to suit your core competency.

    In an organisation, if you are a good speaker, make sure you create opportunities to give presentations that enable the senior management to notice you.

    If your strength is analysis, make sure you do some sort of research, make a report and send it upstairs. Working to your strengths will not only get you noticed but will also create opportunities for growth and advancement.

    The story still hasn`t ended

    The hare and the tortoise, by this time, had become pretty good friends and they did some thinking together. Both realised that the last race could have been run much better.

    So they decided to do the last race again, but to run as a team this time.

    They started off, and this time the hare carried the tortoise till the riverbank. There, the tortoise took over and swam across with the hare on his back.

    On the opposite bank, the hare again carried the tortoise and they reached the finishing line together. They both felt a greater sense of satisfaction than they`d felt earlier.

    The moral of the story? It`s good to be individually brilliant and to have strong core competencies; but unless you`re able to work in a team and harness each other`s core competencies, you`ll always perform below par because there will always be situations at which you`ll do poorly and someone else does well.

    Teamwork is mainly about situational leadership, letting the person with the relevant core competency for a situation take leadership.

    There are more lessons to be learnt from this story.

    Note that neither the hare nor the tortoise gave up after failures. The hare decided to work harder and put in more effort after his failure.

    The tortoise changed his strategy because he was already working as hard as he could. In life, when faced with failure, sometimes it is appropriate to work harder and put in more effort.

    Sometimes it is appropriate to change strategy and try something different. And sometimes it is appropriate to do both.

    The hare and the tortoise also learnt another vital lesson. When we stop competing against a rival and instead start competing against the situation, we perform far better.

    So the new stratregy paradigm is:
    • The fast and consistent will always beat slow & steady;
    • Work to your competencies;
    • Pooling resources & working as a team will always beat individual performers;
    • Never give up when faced with failures;
    • And finally, compete against the situation. Not against a rival. Challenge Ideas and Issues. Not People.

    Configure 24Online for Ubuntu / Linux

    At my home I connect to internet using 24Online. The service of this ISP is pretty good with prompt customer support. I recently installed Ubuntu 11.10 with dual boot on my Windows Vista PC. Ubuntu is a pretty good OS, but without an internet connection there's nothing much you can do with it.

    For Windows, 24Online provides a UI client.


    But for Linux there's no UI client available - only command line utility is available. If you already have an account with 24Online then you can log in your account from browser and download the file from "Client" menu in the website or you can download the file from here (13.2 KB). You can get your IPv4 settings by going to "Control Panel > Network and Sharing Center > Manage Network Connections". Right click on "Local Area Connection" icon and click on "Properties". From the dialog box select "Internet Protocol Version 4 (TCP/IPv4)" and click on "Properties" button. Note down the IP addresses from the fields marked in the screenshot below.

    The first one...

    This is my third attempt at blogging my thoughts and learning. My first attempt ended after 1 month and second one after 3 months. Hopefully this time around I will be able to post at regular intervals.

    I won't be blogging on any specific subject per se. It would be a mixed bag but mainly on technology, but you may find a lot of posts on Lotus Notes and its related technologies like XPages (after all I am in Lotus Notes development).

    And yes, I know the spelling of my blog title is wrong. It's actually a portmanteau of two words - Naveen (that's my name) & Navigator... :) Also I guess all the exciting blog names had already been taken.

    WP7 A better InkPresenter using XNA

      Last week I was at SMAU Italia  together with Matteo Pagani giving a hand at Windows Phone 7 labs and having a good time with my friends at Microsoft. I also got the pleasure to meet Ben Riga. One of the attendees at the laboratory raised a really good question about the performance of the InkPresenter in WP7. He is using the control to capture a signature, but if you are pretty fast (usually people when they do their signature are fast) the result is "ugly" and not really usable. You won't get a smooth curve, but something like this:


     This screenshot is taken in the emulator, but on the real device the curve looks worst and it's easy to reproduce this behavior. I took this "problem" as a challenge (two nights of work and now the third to write the post) convinced that I can get better results with a mix between XNA and Silverlight, mix that in Mango is possible. T
     The main problem is the number of points returned by the event MouseMove of the InkPresenter control which is not enough points to draw a decent curve.
      The first thing I've tried in the XNA version was to use the TouchPanel.GetState() but I was surprised to see that I get the same number of sampling points as the MouseMove in InkPresenter. The things improved a lot when I've used TouchPanel.ReadGesture() with GestureType.FreeDrag. Using these sampling points as StylusPoints for the InkPresenter the situation improved a little:


     The black line is the one obtained with MouseMove and the red one is the one obtained with ReadGesture.The result is better, but not satisfying. The only way to further improve the result was to manually draw the curve without InkPresenter. I've have used BezierSegment to draw the curve. Without any processing this would be the result:


    The new curve is the blue one which is better than the others, but it is still not smooth in some points. This is because a Bézier path is smooth if each endpoint and its two surrounding control points lie in a straight line. In other words, the two tangents at each Bézier endpoint are parallel.



    There is more than one approach to solve this behavior and I've implemented two (with all the mathematics I felt back at the University http://en.wikipedia.org/wiki/B%C3%A9zier_curve). 

    The first is an algorithm for Automatically Fitting Digitized Curves with the Douglas Peucker algorithm to reduce the number of points (http://stackoverflow.com/questions/5525665/smoothing-a-hand-drawn-curve).

    The second one uses Bézier splines which creates the First and Second control points for each Bézier segment http://www.codeproject.com/KB/graphics/BezierSpline.aspx . 

    With both algorithms the results are pretty good:


    If you are interested to play with the sample you can change the following parameters:

    double PhilipSchneiderTolerance = 0;
    double PhilipSchneiderError = 4;
    -used when the fitting algorithm is PhilipSchneider (run this sample http://cid-c27e99281f78a67a.office.live.com/self.aspx/Public/Simplify.zip on the desktop to understand what changes when you change the Tolerance and the Error)

     private bool _showPoints = false;
    -shows or hides the points read by ReadGesture
            
    private bool _showOtherCurves = false;
    -shows or hides the InkPresenter curve using MouseMove and ReadGesture

    private FitCurveAlgorithm _algorithm = FitCurveAlgorithm.PhilipSchneider;
    -changes the fitting algorithm: None, BezierSpline, PhilipSchneider




    P.S. The project still needs some working/polishing in order to be used in production, but that is the simple part so... HAVE FUN

    Skydrive Library for Windows Phone v1

       I've started this project before Build. At that time I didn't know what Microsoft was preparing for the skydrive REST Api so there was no way to fully access your skydrive folders and files. The idea was to be able to get the modified files (word, excel) from Skydrive back to the dropbox account (a lot of people requested that feature and, as you probably know, in Mango you can save the files directly to your skydrive account). So I've started by contacting the people that already had developed applications that use Skydrive for Windows Phone 7 ( it doesn't make sense to reinvent the wheel if you can borrow or buy one) . I've found 2 applications: Sky Wallet and the other Skydrive Player and the answers from the developers were not what I was expected: the first one pointed me to Skydrive.Net which is(was) unusable for Windows Phone and then didn't replied to my other emails (so I understood it was disturbing for him to share his work) and the other said that the source code was not really clean (so more or less I don't want to share it). The only option was to start digging up and find out how they did it (that day I've also promised to myself that i will publish the code even if this will mean that the application I have in the marketplace will loose some value) It took me more than I expected  to understand and implement the mess (for me it's a mess) behind the WebDAV, but the results are not bad ... it works. The source code is quite a mess but it's free and you can use it (if I wait to have time to "clean" the code I will never publish the library). When the REST api will be out of beta (you cannot publish an app with the beta sdk) this library will be obsolete, but till then you can use it in your applications and they will pass certification (at least mine did ... till now ). The list root folder method is slow because I have to call two methods in order to have all the files and folders. You will also find a test project that will show you how to browse your skydrive. Creating folders and uploading files are not implemented in this version and it doesn't make sense to implement them because it will be much easier to do it with the REST api. If you need this functionality contact me and I will point you in the right direction.
      The project is published on Codeplex: http://wp7skydrive.codeplex.com/
      
      If you have questions, need support, or want to improve the library please let me know. If you wanna see a better integration of the library than the simple test project you should buy my dropbox client Boxfiles :) .

    DropBox library for Windows Phone 7 v1.1

     I have just published an updated version of my Dropbox client on CodePlex. You can download it here. I have rewritten the library from scratch (took out all dependencies - Json.Net and Hammock, added the download progress event and a lot of other things that I cannot even remember). It's faster, better and it's the exact same library I am using in my Dropbox application . I really hope that it will be useful for your projects and hope your projects will not be something similar to Boxfiles.
       That's all folks!

    P.S. It doesn't have a test project, but you can use the one in the first release. It should be easy to use and pretty intuitive. If you find bugs or want to improve the library please let me know


    NAMASTE!

    BoxFiles for Dropbox v2 Beta

              Dear readers,
      We've just published the first beta of BoxFiles for Dropbox Mango edition :). The beta is available at: zune://navigate/?appid=8cfa8f66-3174-48e1-99b5-f2d0146113e8 and is limited to the first 100 users that will download the app (if we reach that limit and we still have requests we can publish another beta). We've rewritten most of the source code so it needs a good testing and some feedback. Send your problems/suggestions to: info@neologics.eu .
      The Dropbox library was rewritten from scratch taking out all the 3rd party components (JSON.Net and Hammock), but the featureI am most proud of is the integration with Skydrive. You can now upload your modified Office files back to your Dropbox account.
        We need your help to make our product better. If you can, please tweet the link.

    NAMASTE!

    Mobile HTML5 Speed Reading Again

     Today I've upgrade my iPad 2 to iOS beta 7 and I was thinking that a more "realistic" comparison for the HTML5 Mobile Speed reading would with the new iPhone compared to a new Windows Phone Mango device (new year new hardware). On my Omnia 7 with 7712 build and video drivers not optimized for Mango I get around 30fps, the same that I was getting on my iPhone 4 with iOs5 beta. I remember that on a tweet I read that, on some devices, Windows Phone 7.5 Mango was doing 60 fps. On the other hand the new iPhone will probable have the A5 processor just like the iPad2 so I've run the same test on my device and the results are not bad at all. The iPad2 with iOs5 beta 7 is doing a stable 60fps. This is the frame rate we can expect from the new iPhone.So Apple and Microsoft are, for now, at the same level and let's hope that the OEM's will optimize their video drivers for Mango in order to get 60 fps, if not it could be a boomerang for Microsoft (the new iPhone, doing 60fps, would smash WP7 Mango that is doing 30-40fps). Hope it won't happen.

    Here is the test on the iPad2
