  • Can Near Field Communications (NFC) Benefit your Supply Chain?

    - by Stephen Slade
    Leading firms continue to leverage the latest tools and technologies to drive performance especially around minimizing transaction costs. With razor thin margins in manufacturing and distribution, the leading producers are resorting to Near Field Communications to gain efficiencies.  In this week’s CIO magazine (Apr1, 2012, pg.30, see http://www.cio.com)  Lauren Brousell talks of the things you need to know to make a more informed decision with NFC.  Sandy Shen of Gartner says NFC appeals because "it supports any services that requires data transfer and authentication' 1. NFC is Cheap and Easy - short range transmitting technology connecting smartphones to data transfer. 2. Adoption Seems Inevitable - more merchants will use NCF for payments in the futures. Wallets are becoming obsolete. 3. It's a Hot Potato for Enterprise - Business with credit card companies and cell phone providers are debating who handles the billing process. 4. It's in use Overseas. Japan uses FeliCa to pay by smartphone. In the US, billing agreements are causing territorial conflict. 5. Security Risks Come Standard. As people lose HH devices, security will be an ongoing concern. Credentials and timeout features and alleviate to some extent. My prediction: In 5 years, we won't have wallets in our pockets.  Our secure and all-powerful smart phones will be our electronic portable banks and execute the transaction for us based on our preferences and propensities and electronically execute the transaction for the supply chain.

  • How do I add and/or keep subtitles when converting video?

    - by JoeSteiger
    I have a mkv video I want to convert to mp4, but every which way I try and convert it (Handbrake, WinFF, ffmpeg, mencoder,...I lose the video's subtitles.

  • No NFC for the iPhone, and here's why

    - by David Dorf
    I, like many others in the retail industry, was hoping the iPhone 5 would include an NFC chip that enabled a mobile wallet.  In previous postings I've discussed the possible business case and the foreshadowing of Passbook, but it wasn't meant to be.  A few weeks ago I was considering all the rumors, and it suddenly occurred to me that it wasn't in Apple's best interest to support an NFC chip.  Yes they have patents in this area, but perhaps they are more defensive than indicating new development. Steve Jobs wanted to always win, but more importantly he didn't want others to win at his expense.  It drove him nuts that Windows was more successful than MacOS, and clearly he was bothered by Samsung and other handset manufacturers copying the iPhone.  But he was most angry at Google for their stewardship of Android. If the iPhone 5 had an NFC chip, who would benefit most?  Google Wallet is far and away the leader in NFC-based payments via mobile phones in the US.  Even without Steve at the helm, Apple isn't going to do anything to help Google.  Plus Apple doesn't like to do things in an open way -- then they lose control.  For example, you don't see iPhones with expandable memory, replaceable batteries, or USB connectors.  Adding a standards-based NFC chip just isn't in their nature. So I don't think Apple is holding back on the NFC chip for the 5S or 6.  It just isn't going to happen unless they can figure out how to prevent others from benefiting from it. All the other handset manufacturers will use NFC as a differentiator, which may be enough to keep Google and Isis afloat, and of course Square and PayPal aren't betting on NFC anyway.  This isn't the end of alternative payments, its just a major speed bump.

  • Pointer position way off in Java Application menu's when using gnome-shell

    - by Hailwood
    When using any java application in gnome-shell if the window is maximised the pointer position is way off; but only on the menu's, in the editor, or the side panel, the pointer is fine. This only presents itself when the window is maximized, and it seems that the further away from 0x0 the window is when you maximise it, the bigger the pointer offset. From what I have gathered it has to do with the window not updating it's size when it gets maximised. The other issue is that when a gnome-shell notification appears, when clicking on it, I lose the ability to type in the editor, I can select text etc, but can't give it focus to type. I must bring up some other text input (e.g. right click on a file on the left, select rename, which brings up a rename dialog) after that I can type in the editor again. So, how can I fix this? Below is as much information as I can think to provide $ gnome-shell --version GNOME Shell 3.6.1 $ java -version java version "1.7.0_09" Java(TM) SE Runtime Environment (build 1.7.0_09-b05) Java HotSpot(TM) 64-Bit Server VM (build 23.5-b02, mixed mode) $ file /etc/alternatives/java /etc/alternatives/javac /etc/alternatives/java: symbolic link to '/usr/lib/jvm/java-7-oracle/jre/bin/java' /etc/alternatives/javac: symbolic link to '/usr/lib/jvm/java-7-oracle/bin/javac'

  • SharpSSH gets stuck in an infinite stream read in C# SSH app

    - by Ric Coles
    Afternoon all, I'm having a small problem with the SharpSSH library for .Net (see http://www.tamirgal.com/blog/page/SharpSSH.aspx) SshStream ssh = new SshStream("some ip address", "some username", "some password"); ssh.Prompt = "\n"; ssh.RemoveTerminalEmulationCharacters = true; ssh.Write("ssh some ip address"); // Don't care about this response ssh.ReadResponse(); ssh.Write("lss /mnt/sata[1-4]"); // Don't care about this response (for now) ssh.ReadResponse(); // while the stream can be read while (ssh.CanRead) { Console.WriteLine(ssh.ReadResponse()); } ssh.Close(); As you can see, it's fairly straight forward. However, when the while-loop gets stepped into, it won't break out of the loop when everything has been printed to the console and there is nothing else to read. Is there anyway I can manually force it to break when there is nothing else to be read? Cheers, Ric

  • How do I mix functions in complex SSRS expressions?

    - by Boydski
    I'm writing a report against a data repository that has null values within some of the columns. The problem is building expressions is as temperamental as a hormonal old lady and doesn't like my mixing of functions. Here's an expression I've written that does not work if the data in the field is null/nothing: =IIF( IsNumeric(Fields!ADataField.Value), RunningValue( IIF( DatePart("q", Fields!CreatedOn.Value) = "2", Fields!ADataField.Value, 0 ), Sum, Nothing ), Sum(0) ) (Pseudocode) "If the data is valid and if the data was created in the second quarter of the year, add it to the overall Sum, otherwise, add zero to the sum." Looks pretty straight forward. And the individual pieces of the expression work by themselves. IE: IsNumeric(), DatePart(), etc. But when I put them all together, the expression throws an error. I've attempted about every permutation of what's shown above, all to no avail. Null values in Fields!ADataField.Value cause errors. Thoughts?

  • How can I get something like Nautilus's "spatial" behaviour in 11.10 and later?

    - by Dylan McCall
    Until recently, Nautilus had an optional "spatial" mode as an alternative to its usual browser mode. Users could enable it by opening Nautilus's preferences and selecting "Open each folder in its own window." Choosing this option resulted in a stripped down interface, and folders would always open in the same place on the screen. It looked something like this: That checkbox is still there, but it doesn't do the same thing: while every folder opens in a new window, those windows are all the same size and positioned the same way. Nautilus doesn't restore the size and position of each folder, which is what spatial mode was all about. This difference really shows if someone opens a folder in a new window, and then opens the same folder again. Nautilus will create another window instead of focusing the existing window. I help someone who is currently using Ubuntu 10.04, and he will be upgrading to 12.04 in the future. He is very comfortable with Nautilus's spatial behaviour and I think he would be disappointed to lose it. Is there an alternative file manager, or perhaps some less obvious option, that will give him an interface similar to the one he is comfortable with?

  • Using HTML5 Today part 2&ndash;Fixing Semantic tags with a Shiv

    - by Steve Albers
    Semantic elements and the Shiv! This is the second entry in the series of demos from the “Using HTML5 Today” talk. For the definitive discussion on unknown elements and the HTML5 Shiv check out Mark Pilgrim’s Dive Into HTML5 online book at http://diveintohtml5.info/semantics.html#unknown-elements Semantic tags increase the meaning and maintainability of your markup, help make your page more computer-readable, and can even provide opportunities for libraries that are written to automagically enhance content using standard tags like <nav>, <header>,  or <footer>. Legacy IE issues However, new HTML5 tags get mangled in IE browsers prior to version 9.  To see this in action, consider this bit of HTML code which includes the new <article> and <header> elements: Viewing this page using the IE9 developer tools (F12) we see that the browser correctly models the hierarchy of tags listed above: But if we switch to IE8 Browser Mode in developer tools things go bad: Did you know that a closing tag could close itself?? The browser loses the hierarchy & closes all of the new tags.  The new tags become unusable and the page structure falls apart. Additionally block-level elements lose their block status, appearing as inline.    The Fix (good) The block-level issue can be resolved by using CSS styling.  Below we set the article, header, and footer tags as block tags. article, header, footer {display:block;} You can avoid the unknown element issue by creating a version of the element in JavaScript before the actual HTML5 tag appears on the page: <script> document.createElement("article"); document.createElement("header"); document.createElement("footer"); </script> The Fix (better) Rather than adding your own JS you can take advantage of a standard JS library such as Remy Sharp’s HTML5 Shiv at http://code.google.com/p/html5shiv/.  By default the Modernizr library includes HTML5 Shiv, so you don’t need to include the shiv code separately if you are using Modernizr.

  • Where has my parallel port gone? ioperm(888,1,1) returns -1.

    - by marcusw
    I have an old Dell Dimension 8200 running Gentoo which I use solely to control various things using the parallel port. After shutting it down a few weeks ago, I started it up again today and tried to access the parallel port like I usually do. Unfortunately, my code bombed out when it tried to call ioperm(888,1,1) to grab the parallel port which returned an error code of -1. There have been no changes to the system be it hardware or software, no updates, no tweaking, no dropping the case, no over-amping the data pins, nothing. The port and the software have been working fine for months with no changes, and were working fine when I shut it down last. Running my code with root privileges changes nothing. What is breaking this and how can I fix it?

  • DNS NAmeserver Aname and cname records [closed]

    - by David
    I am inexperienced in the configuration of DNS and have an issue with dominan hosting set up. I have two domains 'www.mydomain1.com' and 'www.mydomain2.com', with mydomain2 pointed at the same place as mydomain1. The domains were passed to me recently by the person who previoulsy controlled them. I have an account with Fasthosts in the UK. When I accepted the domains I could not access the DNS settings and inquired with fasthosts as to why. The reply was: The delegate hosting option for both domains were enabled and this is the reason why you were unable to find the option to edit the advanced DNS records. I have now disabled the delegate hosting option so you can now edit the advanced DNS records for both domains in your account. When I log into the Fasthost control panel now I can access the DNS controls but both domains have no A record or Cname record set up. I am concerned that Fasthosts have blatted the previous Nameserver entries and set me up on theirs but not added any record. 'www.mydomain1.com' currently still works but 'www.mydomain2.com' does not find the site anymore. I am worried I will lose mydomain1 to as the DNS changes filter through the system. my webhosting is at 'xxx.xxx.xxx.xxx/mydomain1.com/' and this is where I want both domains to point. Any advice would be much appreciated. One thing which is confusing me is that because I am on a shared server I have to put 'xxx.xxx.xxx.xxx/mydomain1.com/' to get to my site rather than just 'xxx.xxx.xxx.xxx'. The form on Fasthosts for the A name record only allows an IP to be entered - does it add the mydomain1.com/ onto the end itself? Thanks for any help given - I'm quite worried about this David

  • Wordpress: Create a customized role / user

    - by Mestika
    Hi, I’m farely new to Wordpress but are working on putting a page together which has a very simple purpose. I’m creating it for a customer with little or none IT experience so I want to create a user he can use to login and edit his pages – and nothing more. No settings, no comments, no posts, no links, no nothing, just create, delete and edit pages and maybe edit his own profile or at least his E-mail and password. I can see that wordpress has some predefined roles for users but none of them completely does what I want and they either has to little or to many rights. I’ve been looking at the wordpress page http://codex.wordpress.org/Roles_and_Capabilities but can’t seem to get a clear answer. Is it in any way possible for me to create my own user role (e.g. customer) where I can set the rights I want for him? Thanks Sincerely Mestika

  • Design of input files reading when it comes to defaults/transformations

    - by Stefano Borini
    Suppose you have an application that reads an input file, on a language that does not support the concept of None. The input is read, parsed, and the contents are stored on a structure for later use. Now, in general you want to keep into account transformation of the data from the input, such as adding default values when not specified, or adding full path information to relative path specified in the input. There are two different strategies to achieve this. The first strategy is to perform these transformations at input file reading time. In practice, you put all the intelligence into the input parser, and your application has no logic to deal with unexpected circumstances, such as an unspecified value. You lose the information of what was specified and what wasn't, but you gain in black-boxing the details. Your "running code" needs that information in any case and in a proper form, and is not concerned if it's the default or a user-specified information. The second strategy is to have the file reader a real one-to-one mapper from the file to a memory-stored object, with no intelligent behavior. unspecified values are not filled (which may however be a problem in languages not supporting None) and data is stored verbatim from the file. The intelligence for recovery must now go into the "running code", which must check what was specified in the file, eventually fall back to a default, or modify the input properly before using it. I would like to know your opinion on these two approaches, and in particular which one you found the most frequently implemented.

  • Visual C# 2010 express... displaying console output??

    - by ClarkeyBoy
    Hi, I am currently creating a customer application for a local company. I have a datagridview linked to the customers table, and I am trying to link it up so that updates, inserts and deletions are handled correctly. I am very new to c# so I am starting with the basics (like about 2 days ago I knew nothing - I know vb.net, Java and several other languages though..). Anywho from what I understand anything output through Debug.WriteLine should only appear when in debug mode (common sense really) but anything output through Concole.WriteLine should appear whether or not in debug mode. However I have checked the immediate and output windows and nothing is being output when in normal mode. Does anyone have any idea why this is?? Thanks in advance, Richard

  • Neither IE or Firefox respects the control values that are output

    - by Luke Rohde
    I'm writing a survey designer asp.net mvc. It has buttons to move questions up and down. The buttons post the whole form back and the affected questions are swapped on the server. When the form returns the only thing that is changed are the values for each survey question. Both firefox and IE seem to ignore this change. Nothing is persisted to the database (until save) and url doesn't change so the post just returns the same view but I've stepped through my code to ensure the sequence of values being rendered in the view reflects the swap which is ok. However "view - source" doesn't show the change suggesting caching issue (maybe auto complete). I've tried autocomplete="off" in my form. Response.Cache.SetNoStore(); in my global.asax [System.Web.Mvc.OutputCache(NoStore = true, Duration = 0, VaryByParam = "*")] before my controller and the following in my page header NOTHING!!! This must be real common. Anyone got a clue?

  • Good Laptop .NET Developer VM Setup

    - by Steve Brouillard
    I was torn between putting this question on this site or SuperUsers. I've tried to do a good bit of searching on this, and while I find plenty of info on why to go with a VM or not, there isn't much practical advise on HOW to best set things up. Here's what I currently HAVE: HP EliteBook 1540, quad-core, 8GB memory, 500GB 7200 RPM HD, eSATA port. Descent machine. Should work just fine. Windows 7 64-bit Host OS. This also acts as my day-to-day basic stuff (email, Word Docs, etc...) OS. VMWare Desktop Windows 7 64-bit Guest OS with all my .NET dev tools, frameworks, etc loaded on it. It's configured to use 2 cores and up to 6GB of memory. I figure that the dev env will need more than email, word, etc... So, this seemed like a good option to me, but I find with the VM running, things tend to slow down all around on both the host and guest OS. Memory and CPU utilization don't seem to be an issue, but I/O does. I tried running the VM on an external eSATA drive, figuring that the extra channel might pick up the slack. Things only got worse (could be my eSATA enclosure). So, for all of that I have basically two questions in one. Has anyone used this sort of setup and are there any gotchas either around the VMWare configuration or anything else I may have missed here that you can point me to? Is there another option that might work better? For example, I've considered trying a lighter weight Host OS and run both of my environments as VMs? I tried this with Server 2008 Hyper-V, but I lose too much laptop functionality going this route, so I never completed setup. I'm not averse to Linux as a host OS, though I'm no Linux expert. If I'm missing any critical info, feel free to ask. Thanks in advance for your help. Steve

  • Should my dropdown of recently used items show items I no longer have access to

    - by Dan Hibbert
    We are implementing a client for our document management system. Part of this is the checkin screen where one of the fields a user chooses is the folder where the document should be checked into. In our original system, this was represented with a combobox where a user could hand type a folder path or select a path from a list of 5 folders they'd recently used for checking. It is possible that between the time they used the folder and the time they are doing the new checkin the user will no longer have access to the folder. At present, we still show the folder as an option and then, if the user chooses that folder, display an error message when the user submits the check in. We are thinking of removing these recently used folders the user doesn't have access to (we'll make a check when the form is instantiated) because why show an option if we know it will cause a failure (and another dialog message the user has to OK). However, an opposite opinion is that if we remove those folders, the users will think the system has "forgotten" their recent choices and will lose trust in what they are using. I'd like to get some opinions on the better user experience for this problem.

  • Is adding indexes to a SQL Server ever a bad idea?

    - by Aerik
    We have a mid-size SQL Server based application that has no indexes defined. Not even on the the identity columns. I suggested to our moderately expensive application consultant that perhaps we might get better performance (particularly as our database grows) by creating some indexes on appropriate fields, and he said: "Indexes will significantly impact other areas of the application and customers should not create them under any circumstances." Anybody ever heard of anything like this? Are there ever circumstances where one should not create any indexes? I can see nothing special about this app - it's got int identity columns, then lots of string columns, bunch of relational tables but nothing special or weird that I can see. Thanks!

  • AVD Screen orientation not changing with CTRL+F11 or CTRL+F12

    - by Brad Hein
    I run my app in the AVD emulator using eclipse but I'm unable to change the screen orientation in the AVD (Android 2.0 platform on the emulator). When I press CONTROL+F11 or CONTROL+F12 on the keyboard, nothing happens. No messages are generated in the adb debuglog/logcat either when I press either hotkey. According to http://developer.android.com/guide/developing/tools/emulator.html these are the correct hotkeys to switch the emulator's screen orientation. I tried it with my app, and with the messaging app. The hotkey has no affect in any case. I'm running Fedora 12, Gnome. I checked my Keyboard Shortcuts in the System - Preferences menu, nothing's attached to either hotkey. Same problem, 3 different PCs (all running Fedora Gnome).

  • Git push won't do anything (Everything up-to-date)

    I'm trying to update a git repository on github. I made a bunch of changes, added them, committed then attempted to do a git push.

[searchgraph] git status # On branch develop # Changes to be committed: # (use "git reset HEAD <file>..." to unstage) # # new file: Capfile # new file: config/deploy.rb # [searchgraph] git commit -m "Added Capistrano deployment" [develop 12e8af7] Added Capistrano deployment 2 files changed, 26 insertions(+), 0 deletions(-) create mode 100644 Capfile create mode 100644 config/deploy.rb [searchgraph] git push Everything up-to-date [searchgraph] git status # On branch develop nothing to commit (working directory clean)

  • Design Application to "Actively" Invite Users (pretend they have privileges)

    - by user3086451
    I am designing an application where users message one another privately, and may send messages to any Entity in the database (an Entity may not have a user account yet, it is a professional database). I am not sure how to best design the database and the API to allow messaging unregistered users. The application should remain secure, and data only accessed by those with correct permissions. Messages sent to persons without user accounts serve as an invitation. The invited person should be able to view the message, act on it, and complete the user registration upon receiving an InviteMessage. In simple terms, I have: User misc user fields (email, pw, dateJoined) Entity (large professional dataset): personalDetails... user->User (may be null) UserMessage: sender->User recipient->User dateCreated messageContent, other fields..... InviteMessage: sender->User recipient->Entity expiringUrl inviteeEmail inviteePhone I plan to alert the user when selecting a recipient that is not registered yet, and inform that he may send the message as an invitation by providing email, phone where we can send the invitation. Invitations will have a unique, one-time-use URL, e.g. uuid.uuid4(). When accessed, the invitee will see the InviteMessage and details about completing his/her registration profile. When registration is complete, InviteMessage details to a new instance of UserMessage (to not lose their data), and assign it to the newly created User. The ability to interact with and invite persons who do not yet have accounts is a key feature of the application, and it seems better to separate the invitation from the private, app messages (easier to keep functionality separate, better if data model changes). Is this a reasonable, good design? If not, what would you suggest? Do you have any improvements? Am I correct to choose to create a separate endpoint for creating invitations via the API?

  • Release Excel Object In My Destructor

    - by Murat
    Hi all, I'm writing a Excel class using Microsoft.Interropt.Excel DLL. I finish all function but I have an error in my Destructor. I Want to save all changes to my file and I want to release all source. I want to all of them in my destructor. But In my destructor, Excel.ApplicationClass, Workbook and Worksheet objects are fill by an Exception which have message "COM object that has been separated from its underlying RCW cannot be used." So I can't save nothing, close nothing because i can't access workbook or worksheet object. Can't I access the class private members in Destructor?
