  • How backward compatible are the HSDPA mobile networks

    - by Chris Kimpton
    Hi, I have got this Huawei wifi device, which has been unlocked for other networks. Works fine in UK on Vodafone (as well as 3). We are trying to get it to work with the Claro network in Jamaica. It connects and stays connected, but fails to get a 3g connection, just the slow EDGE one. Claro support say its because Claro currently does not support the 2100MHz frequency for 3G, which is what the device uses Does that sound correct? They say I need one that: Ensure however that these devices can use the 850MHz frequency. My understanding was that the device supports up to 2100, including their 850mhz... I am thinking that maybe the APN is incorrect, but I have set it to the only value I can find on the net, namely: internet.ideasclaro.com.jm Thanks in advance, Chris

    - by Igoru
    I've had some problems with Bluetooth in my Ubuntu 9.10, and ended up by uninstalling everything related. I would like to know what are the default packages for BTH in Ubuntu, and what are your recommendations (like blueman or thing like this). I have a high-end cellphone and would like to use everything that's possible, talking about bluetooth, with it (a samsung scrapy touch, or GT-B3410).

  • Is there such a thing as an IP femtocell, and what does it do?

    - by The Journeyman geek
    My dad mentioned a co-worker suggested using a device, that might use CDMA to route calls through IP to save costs on a certain overseas project we're on- since our home base is quite far from there. I've never heard of such a device, so if it does exist, I'm wondering, if it's specific to particular ISPs, or if you can just pick one off the shelf, plug it into an arbitrary Internet connection, and make calls using it and a cellphone of some sort? As you can tell, details are sketchy, so... if such a device doesn't exist, saying so might be a right answer ;)

  • Why doesn't my Droid phone charge when connected to a powered USB hub that is not connected to my computer?

    - by pkaeding
    I notice that my new Motorola Droid phone charges perfectly fine when I connect it to my computer via the USB cable, or if I connect it to a car cigarette lighter-USB adapter, or a wall power-USB adapter. It also works fine when I connect it to a powered USB hub that is connected to my computer. However, if that same powered USB hub is not connected to my computer when I connect the phone, it does not charge. If I connect the computer to the hub, and then connect the phone to the hub, it will charge. If I then disconnect the computer from the hub, the phone will continue to charge. Does anyone know why this is happening, or what I can do to be able to charge my phone from a powered hub, without my computer being present?

  • Using a PC + headset as a telephone without VOIP

    - by user76782
    I'm trying to find a way to realize a decentralized callcenter, so that the callcenter agents can talk from their home office with just a PC + headset. The big challange is that some of the agents have very low bandwith and the quality with VOIP is too bad. So my question is: What other solutions are possible when VOIP is not a option? What exactly do I need to do if I try to achieve this with for example Landline/PBX or GSM? (e.g. Which software do I need to install? Which device do I need?)

  • Identifying the version of ATI Catalyst drivers

    - by Snark
    I have bought a new video card based on the ATI Radeon HD 5670 chipset. I couldn't make it work with the latest ATI Catalyst drivers found on their website, only the drivers found on the CD delivered with the card worked. How can I know the version of Catalyst that is installed on my PC (running Windows 7 64-bits)? The ATI Catalyst Control Center returns the following information: Driver Packaging Version 8.673-091110a-092263C Provider ATI Technologies Inc. 2D Driver Version 8.01.01.973 2D Driver File Path /REGISTRY/MACHINE/SYSTEM/ControlSet001/Control/CLASS/{4D36E968-E325-11CE-BFC1-08002BE10318}/0000 Direct3D Version 8.14.10.0708 OpenGL Version 6.14.10.9120 Catalyst™ Control Center Version 2009.1110.2225.40230 I do not recognize anything pointing to a "marketing version". The website says the current version of Catalyst is 10.2.

  • How can I share data from a Samsung Wave Mobile phone with the Mac OS?

    - by M. Bedi
    This is driving me up the wall just a bit. I have a new Samsung Wave mobile phone. It is running the Bada OS. The mobile phone does not come with anyone software for the Mac. The Kies desktop interface is only available for Windows. I did try installing the Kies software in a VM with Parallels 5 but it did not detect the phone connected via USB. I tried using Bluetooth file exchange on the Mac; it lets me browse the file system on the Wave phone but not actually see any of the media files; I just get empty directory views. But I am able to access files using media sharing with the Wave phone and my PS3. So what would be a Mac desks top app that can be used a media sharing browser?

  • Cannot download or send MMS

    - by CGFoX
    I have a Huawei Honor with Android 4.0.3. I got a plan at AT&T that includes 200 messages (both SMS and MMS) per month. Unfortunately I can neither receive nor send MMS. When I receive one, there's a download-button. But when I hit download it doesn't do anything, even when I got internet connection via wifi. When I try to send a MMS it only says "sending...", but nothing happens. My guess is that I didn't configure the settings correctly, but I couldn't find anything useful online. Also I don't have a single APN. Maybe I need to create one? Thanks for your help!

  • Receiving and processing SMS messages through a script?

    - by ShankarG
    I am attempting to setup a system to receive and process SMS messages automatically. The system is intended for use in a context (an unfunded migrant workers' union in India) where both finances and sysadmin skills are extremely constrained (I would be the only person, in the near future, who would be administering the system). The intention is to make some functions - registration of members, generation of ID cards, communication of alerts and other information - easier. However, for receiving and sending SMS, I have not been able to find any email to SMS or other kind of gateway that functions in India. Perhaps there is one (edit: apparently Clickatell does have an India service, but the prices appear astronomical). If not, can one rely on a USB mobile modem (such as those provided by many mobile providers in India)? It seems like, with utilities such as gammu or bitpim, SMS operations on such a modem could be scripted. Is this actually feasible, though? Thanks in advance for your thoughts and suggestions. edit: Original first question removed since the two questions had little to do with each other. The original first question has been asked separately here

  • Why is my /dev/random so slow when using dd?

    - by Mikey
    I am trying to semi-securely erase a bunch of hard drives. The following is working at 20-50Mb/s dd if=/dev/zero of=/dev/sda But dd if=/dev/random of=/dev/sda seems not to work. Also when I type dd if=/dev/random of=stdout It only gives me a few bytes regardless of what I pass it for bs= and count= Am I using /dev/random wrong? What other info should I look for to move this troubleshooting forward? Is there some other way to do this with a script or something like makeMyLifeEasy | dd if=stdin of=/dev/sda Or something like that...

  • Running Hyper-V and VMWare together

    - by Shiki
    I have two virtualization software on one of my laptops which is dedicated to Windows 8 development. A VMWare for generic virtualization and the Windows 8 like Hyper-V for the WP8 SDK. Unfortunately these softwares don't like each other. Is there a way to get them play along? The exact problem is that if I install the SDK, VMWare won't even update or run. There is only one way to make them work. Switch Hyper-V on and off. Which is one restart all the time.

  • jQuery Templates and Data Linking (and Microsoft contributing to jQuery)

    - by ScottGu
    The jQuery library has a passionate community of developers, and it is now the most widely used JavaScript library on the web today. Two years ago I announced that Microsoft would begin offering product support for jQuery, and that we’d be including it in new versions of Visual Studio going forward. By default, when you create new ASP.NET Web Forms and ASP.NET MVC projects with VS 2010 you’ll find jQuery automatically added to your project. A few weeks ago during my second keynote at the MIX 2010 conference I announced that Microsoft would also begin contributing to the jQuery project.  During the talk, John Resig -- the creator of the jQuery library and leader of the jQuery developer team – talked a little about our participation and discussed an early prototype of a new client templating API for jQuery. In this blog post, I’m going to talk a little about how my team is starting to contribute to the jQuery project, and discuss some of the specific features that we are working on such as client-side templating and data linking (data-binding). Contributing to jQuery jQuery has a fantastic developer community, and a very open way to propose suggestions and make contributions.  Microsoft is following the same process to contribute to jQuery as any other member of the community. As an example, when working with the jQuery community to improve support for templating to jQuery my team followed the following steps: We created a proposal for templating and posted the proposal to the jQuery developer forum (http://forum.jquery.com/topic/jquery-templates-proposal and http://forum.jquery.com/topic/templating-syntax ). After receiving feedback on the forums, the jQuery team created a prototype for templating and posted the prototype at the Github code repository (http://github.com/jquery/jquery-tmpl ). We iterated on the prototype, creating a new fork on Github of the templating prototype, to suggest design improvements. Several other members of the community also provided design feedback by forking the templating code. There has been an amazing amount of participation by the jQuery community in response to the original templating proposal (over 100 posts in the jQuery forum), and the design of the templating proposal has evolved significantly based on community feedback. The jQuery team is the ultimate determiner on what happens with the templating proposal – they might include it in jQuery core, or make it an official plugin, or reject it entirely.  My team is excited to be able to participate in the open source process, and make suggestions and contributions the same way as any other member of the community. jQuery Template Support Client-side templates enable jQuery developers to easily generate and render HTML UI on the client.  Templates support a simple syntax that enables either developers or designers to declaratively specify the HTML they want to generate.  Developers can then programmatically invoke the templates on the client, and pass JavaScript objects to them to make the content rendered completely data driven.  These JavaScript objects can optionally be based on data retrieved from a server. Because the jQuery templating proposal is still evolving in response to community feedback, the final version might look very different than the version below. This blog post gives you a sense of how you can try out and use templating as it exists today (you can download the prototype by the jQuery core team at http://github.com/jquery/jquery-tmpl or the latest submission from my team at http://github.com/nje/jquery-tmpl).  jQuery Client Templates You create client-side jQuery templates by embedding content within a <script type="text/html"> tag.  For example, the HTML below contains a <div> template container, as well as a client-side jQuery “contactTemplate” template (within the <script type="text/html"> element) that can be used to dynamically display a list of contacts: The {{= name }} and {{= phone }} expressions are used within the contact template above to display the names and phone numbers of “contact” objects passed to the template. We can use the template to display either an array of JavaScript objects or a single object. The JavaScript code below demonstrates how you can render a JavaScript array of “contact” object using the above template. The render() method renders the data into a string and appends the string to the “contactContainer” DIV element: When the page is loaded, the list of contacts is rendered by the template.  All of this template rendering is happening on the client-side within the browser:   Templating Commands and Conditional Display Logic The current templating proposal supports a small set of template commands - including if, else, and each statements. The number of template commands was deliberately kept small to encourage people to place more complicated logic outside of their templates. Even this small set of template commands is very useful though. Imagine, for example, that each contact can have zero or more phone numbers. The contacts could be represented by the JavaScript array below: The template below demonstrates how you can use the if and each template commands to conditionally display and loop the phone numbers for each contact: If a contact has one or more phone numbers then each of the phone numbers is displayed by iterating through the phone numbers with the each template command: The jQuery team designed the template commands so that they are extensible. If you have a need for a new template command then you can easily add new template commands to the default set of commands. Support for Client Data-Linking The ASP.NET team recently submitted another proposal and prototype to the jQuery forums (http://forum.jquery.com/topic/proposal-for-adding-data-linking-to-jquery). This proposal describes a new feature named data linking. Data Linking enables you to link a property of one object to a property of another object - so that when one property changes the other property changes.  Data linking enables you to easily keep your UI and data objects synchronized within a page. If you are familiar with the concept of data-binding then you will be familiar with data linking (in the proposal, we call the feature data linking because jQuery already includes a bind() method that has nothing to do with data-binding). Imagine, for example, that you have a page with the following HTML <input> elements: The following JavaScript code links the two INPUT elements above to the properties of a JavaScript “contact” object that has a “name” and “phone” property: When you execute this code, the value of the first INPUT element (#name) is set to the value of the contact name property, and the value of the second INPUT element (#phone) is set to the value of the contact phone property. The properties of the contact object and the properties of the INPUT elements are also linked – so that changes to one are also reflected in the other. Because the contact object is linked to the INPUT element, when you request the page, the values of the contact properties are displayed: More interesting, the values of the linked INPUT elements will change automatically whenever you update the properties of the contact object they are linked to. For example, we could programmatically modify the properties of the “contact” object using the jQuery attr() method like below: Because our two INPUT elements are linked to the “contact” object, the INPUT element values will be updated automatically (without us having to write any code to modify the UI elements): Note that we updated the contact object above using the jQuery attr() method. In order for data linking to work, you must use jQuery methods to modify the property values. Two Way Linking The linkBoth() method enables two-way data linking. The contact object and INPUT elements are linked in both directions. When you modify the value of the INPUT element, the contact object is also updated automatically. For example, the following code adds a client-side JavaScript click handler to an HTML button element. When you click the button, the property values of the contact object are displayed using an alert() dialog: The following demonstrates what happens when you change the value of the Name INPUT element and click the Save button. Notice that the name property of the “contact” object that the INPUT element was linked to was updated automatically: The above example is obviously trivially simple.  Instead of displaying the new values of the contact object with a JavaScript alert, you can imagine instead calling a web-service to save the object to a database. The benefit of data linking is that it enables you to focus on your data and frees you from the mechanics of keeping your UI and data in sync. Converters The current data linking proposal also supports a feature called converters. A converter enables you to easily convert the value of a property during data linking. For example, imagine that you want to represent phone numbers in a standard way with the “contact” object phone property. In particular, you don’t want to include special characters such as ()- in the phone number - instead you only want digits and nothing else. In that case, you can wire-up a converter to convert the value of an INPUT element into this format using the code below: Notice above how a converter function is being passed to the linkFrom() method used to link the phone property of the “contact” object with the value of the phone INPUT element. This convertor function strips any non-numeric characters from the INPUT element before updating the phone property.  Now, if you enter the phone number (206) 555-9999 into the phone input field then the value 2065559999 is assigned to the phone property of the contact object: You can also use a converter in the opposite direction also. For example, you can apply a standard phone format string when displaying a phone number from a phone property. Combining Templating and Data Linking Our goal in submitting these two proposals for templating and data linking is to make it easier to work with data when building websites and applications with jQuery. Templating makes it easier to display a list of database records retrieved from a database through an Ajax call. Data linking makes it easier to keep the data and user interface in sync for update scenarios. Currently, we are working on an extension of the data linking proposal to support declarative data linking. We want to make it easy to take advantage of data linking when using a template to display data. For example, imagine that you are using the following template to display an array of product objects: Notice the {{link name}} and {{link price}} expressions. These expressions enable declarative data linking between the SPAN elements and properties of the product objects. The current jQuery templating prototype supports extending its syntax with custom template commands. In this case, we are extending the default templating syntax with a custom template command named “link”. The benefit of using data linking with the above template is that the SPAN elements will be automatically updated whenever the underlying “product” data is updated.  Declarative data linking also makes it easier to create edit and insert forms. For example, you could create a form for editing a product by using declarative data linking like this: Whenever you change the value of the INPUT elements in a template that uses declarative data linking, the underlying JavaScript data object is automatically updated. Instead of needing to write code to scrape the HTML form to get updated values, you can instead work with the underlying data directly – making your client-side code much cleaner and simpler. Downloading Working Code Examples of the Above Scenarios You can download this .zip file to get with working code examples of the above scenarios.  The .zip file includes 4 static HTML page: Listing1_Templating.htm – Illustrates basic templating. Listing2_TemplatingConditionals.htm – Illustrates templating with the use of the if and each template commands. Listing3_DataLinking.htm – Illustrates data linking. Listing4_Converters.htm – Illustrates using a converter with data linking. You can un-zip the file to the file-system and then run each page to see the concepts in action. Summary We are excited to be able to begin participating within the open-source jQuery project.  We’ve received lots of encouraging feedback in response to our first two proposals, and we will continue to actively contribute going forward.  These features will hopefully make it easier for all developers (including ASP.NET developers) to build great Ajax applications. Hope this helps, Scott P.S. [In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu]

  • Windows Phone 7 Connect to SharePoint via SOAP

    - by Mitchell Skurnik
    I am making my second application for the Windows 7 Phone Series platform and I cannot seem to connect to a SharePoint server using https. 99% of the following is not my code. I have borrowed it from http://blog.daisley-harrison.com/blog/post/Practical-Silverlight-and-SharePoint-Integration-Part-Two.aspx untill I can further understand how SOAP works in W7P Series. I know that I need some way of sending credentials over but the win 7 API does not seem to let you.

If you dig down into the error output it says access is denied. I have tried various methods of sending credentials but none seem to work. "ClientCredentials.Windows" is not supported and ClientCredentials.UsersName.Username is read only.

  • "Could not establish secure channel for SSL/TLS" in .NET CF application on smart phone

    - by Stefan Mohr
    I have a stubborn communications issue with an application running on the .NET Compact Framework 3.5 on Windows Mobile smartphones. I am constructing a web request using this code: UTF8Encoding encoding = new System.Text.UTF8Encoding(); byte[] Data = encoding.GetBytes(HttpUtility.ConstructQueryString(parameters)); httpRequest = WebRequest.Create((domain)) as HttpWebRequest; httpRequest.Timeout = 10000000; httpRequest.ReadWriteTimeout = 10000000; httpRequest.Credentials = CredentialCache.DefaultCredentials; httpRequest.Method = "POST"; httpRequest.ContentType = "application/x-www-form-urlencoded"; httpRequest.ContentLength = Data.Length; Stream SendReq = httpRequest.GetRequestStream(); SendReq.Write(Data, 0, Data.Length); SendReq.Close(); HttpWebResponse httpResponse = (HttpWebResponse)httpRequest.GetResponse(); return httpResponse.GetResponseStream(); The web service functions by receiving a JSON-encoded document as part of the URL (eg. https://site.com/ws/sync??document={"version":"1.0.0","items":[{"item_1":"item1"}]}&user=usr&password=pw), and as a response receives another JSON document as response data. This code runs fine on all emulators and PDAs running WM 5 and 6. We have seen an issue with a couple of customers running Treo smartphones (and only on the Sprint network). We have tested the code on an identical device on the AT&T network (via DeviceAnywhere) and once again the code worked as we expected. This has to be some sort of security policy on the phone, but we've been unable to determine a workaround or diagnose it thoroughly as we cannot reproduce it in house and have had to resort to getting users to assist with running test drivers for us. When this code executes, the user's device throws the following exception: System.Net.WebException Could not establish secure channel for SSL/TLS Stack trace: at System.Net.HttpWebRequest.finishGetRequestStream() at System.Net.HttpWebRequest.GetRequestStream() at OurApp.GetResponseStream(String domain, Hashtable parameters) inner exception: System.IO.IOException Authentication failed because the remote party has closed the transport stream. Stack trace: at System.Net.SslConnectionState.ClientSideHandshake() at System.Net.SslConnectionState.PerformClientHandShake() at System.Net.Connection.connect(Object ignored) at System.Threading.ThreadPool.WorkItem.doWork(Object o) at System.Threading.Timer.ring() Examining the server Apache logs shows no hits from the user's IP - I don't think the device is even attempting to send a packet before failing. If relevant, the server is running Apache on Linux and is written using the TurboGears Python framework. The server certificate is issued by a CA and is still valid. The test driver where this error was copied from was not code signed, however the same error (without the error messages) is signed with a GeoTrust certificate so we don't believe this is a code signing issue. The application installs and launches without issue on all phones - it's just establishing this SSL connection that is breaking for these users. One significant issue in troubleshooting is that there is a substantial inconvenience each time we try out a solution (need to find a "volunteer" customer), so we're really looking for a silver bullet or a better understanding of the handshaking process so we can be reasonably confident we only need to ask the user to test it one or two more times. One final mention: we have tried the sync both over ActiveSync and also over GPRS with identical results. Any thoughts would be greatly appreciated!

    Histogram -------------------------------------------------------- 1 ****(4) 2 ******(6) 3 ***********(11) 4 *****************(17) 5 **************************(26) 6 *************************(25) 7 *******(7) 8 ***(3) 9 (0) 10 *(1) -------------------------------------------------------- basically above is what my prgram needs to do.. im missing something somewhere any help would be great :) import java.util.Random; public class Histogram { /*This is a program to generate random number histogram between 1 and 100 and generate a table */ public static void main(String args[]) { int [] randarray = new int [80]; Random random = new Random(); System.out.println("Histogram"); System.out.println("---------"); int i ; for ( i = 0; i<randarray.length;i++) { int temp = random.nextInt(100); //random numbers up to number value 100 randarray[i] = temp; } int [] histo = new int [10]; for ( i = 0; i<10; i++) { /* %03d\t, this generates the random numbers to three decimal places so the numbers are generated with a full number or number with 00's or one 0*/ if (randarray[i] <= 10) { histo[i] = histo[i] + 1; //System.out.println("*"); } else if ( randarray[i] <= 20){ histo[i] = histo[i] + 1; } else if (randarray[i] <= 30){ histo[i] = histo[i] + 1; } else if ( randarray[i] <= 40){ histo[i] = histo[i] + 1; } else if (randarray[i] <= 50){ histo[i] = histo[i] + 1; } else if ( randarray[i] <=60){ histo[i] = histo[i] + 1; } else if ( randarray[i] <=70){ histo[i] = histo[i] + 1; } else if ( randarray[i] <=80){ histo[i] = histo[i] + 1; } else if ( randarray[i] <=90){ histo[i] = histo[i] + 1; } else if ( randarray[i] <=100){ histo[i] = histo[i] + 1; } switch (randarray[i]) { case 1: System.out.print("0-10 | "); break; case 2: System.out.print("11-20 | "); break; case 3: System.out.print("21-30 | "); break; case 4: System.out.print("31-40 | "); break; case 5: System.out.print("41-50 | "); break; case 6: System.out.print("51-60 | "); break; case 7: System.out.print("61-70 | "); break; case 8: System.out.print("71-80 | "); break; case 9: System.out.print("81-90 | "); break; case 10: System.out.print("91-100 | "); } for (int i = 0; i < 80; i++) { randomNumber = random.nextInt(100) index = (randomNumber - 1) / 2; histo[index]++; } } } }

  • how to make a javascript number keypad popup

    - by user2434653
    i have a website with 3 pages. each page has a form with two input fields. i am trying to make a popup number-keypad that will populate what ever input field called it. below is that base code i keep coming back to. <html> <head><title>test</title></head> <body> <script> function num(id) { return document.getElementById(id); } </script> <form action="/unitPage" method="POST" style=" text-align:center;"> Prefix: <input id="num" name"prefix" type="text" onfocus="num('keypad').style.display='inline-block';"/> Number: <input id="num" name"number" type="text" pattern="[0-9]{6}" onfocus="num('keypad').style.display='inline-block';"/> </form> <div id="keypad" style="display:none; background:#AAA; vertical-align:top;"> <input type="button" value="7" onclick="num('num').value+=7;"/> <input type="button" value="8" onclick="num('num').value+=8;"/> <input type="button" value="9" onclick="num('num').value+=9;"/><br/> <input type="button" value="4" onclick="num('num').value+=4;"/> <input type="button" value="5" onclick="num('num').value+=5;"/> <input type="button" value="6" onclick="num('num').value+=6;"/><br/> <input type="button" value="1" onclick="num('num').value+=1;"/> <input type="button" value="2" onclick="num('num').value+=2;"/> <input type="button" value="3" onclick="num('num').value+=3;"/><br/> <input type="button" value="X" onclick="num('keypad').style.display='none'"/> <input type="button" value="0" onclick="num('num').value+=0;"/> <input type="button" value="&larr;" onclick="num('num').value=num('num').value.substr(0,num('num').value.length-1);"/> </div> </body> </html> is there a way of making one number key pad that i call from any page or do i need to make the above for each input? thanks

    I created a program to show the sum and show the reversed number a person has typed. The sum function works but the revers function is not. Can anyone give me any tips on how to fix it.
