  • Sync offline JQuery Mobile form

    - by Dimas
    My name is Dimas and I work as a developer in a hospital. I've developed a web form with JQuery Mobile which is accessed from an Android tablet. It sends data (text and FILES) to the server (PHP) and it's saved in a MySQL database. This tablets are used by doctors that are visiting the patients in their homes. Some of these patients live in remote areas with very bad Internet connection, so I'm thinking on use HTML5 Offline feature to solve these situations. I started reading about it but I'm newbie with this technology. I've some questions: Do you think this is the best/easiest solution? If I could save the form data in a local sqlite storage when the tablet is offline, how I could synchronize it with the data in MySQL server when the tablet become online? Thanks

  • C/C++ detect network type

    - by Gavimoss
    I need to write a win32 c/c++ application which will be able to determine whether the PC it's running on is connected to one of 2 networks. The first network is the company LAN (which has no internet connection) and the second network is a standalone switch with a single PC connected to it (the PC that the program is running on). I'm pretty new to network programming but so far I have tried testing to see if a network drive which is held on our LAN can be mapped. This works fine if the PC is connected to the LAN, the drive mapping succeeds so so LAN detection is successful. However, if the PC is connected to the switch, this results in a VERY long timeout which is not a suitable as it will delay the program so much as to make it unusable. Does anyone have any alternative suggestions? I'm using c/c++ in VS 6.0

  • Installing the Updated XP Mode which Requires no Hardware Virtualization

    - by Mysticgeek
    Good news for those of you who have a computer without Hardware Virtualization, Microsoft had dropped the requirement so you can now run XP Mode on your machine. Here we take a look at how to install it and getting working on your PC. Microsoft has dropped the requirement that your CPU supports Hardware Virtualization for XP Mode in Windows 7. Before this requirement was dropped, we showed you how to use SecureAble to find out if your machine would run XP Mode. If it couldn’t, you might have gotten lucky with turning Hardware Virtualization on in your BIOS, or getting an update that would enable it. If not, you were out of luck or would need a different machine. Note: Although you no longer need Hardware Virtualization, you still need Professional, Enterprise, or Ultimate version of Windows 7. Download Correct Version of XP Mode For this article we’re installing it on a Dell machine that doesn’t support Hardware Virtualization on Windows 7 Ultimate 64-bit version. The first thing you’ll want to do is go to the XP Mode website and select your edition of Windows 7 and language. Then there are three downloads you’ll need to get from the page. Windows XP Mode, Windows Virtual PC, and the Windows XP Mode Update (All Links Below). Windows genuine validation is required before you can download the XP Mode files. To make the validation process easier you might want to use IE when downloading these files and validating your version of Windows. Installing XP Mode After validation is successful the first thing to download and install is XP Mode, which is easy following the wizard and accepting the defaults. The second step is to install KB958559 which is Windows Virtual PC.   After it’s installed, a reboot is required. After you’ve come back from the restart, you’ll need to install KB977206 which is the Windows XP Mode Update.   After that’s installed, yet another restart of your system is required. After the update is configured and you return from the second reboot, you’ll find XP Mode in the Start menu under the Windows Virtual PC folder. When it launches accept the license agreement and click Next. Enter in your log in credentials… Choose if you want Automatic Updates or not… Then you’re given a message saying setup will share the hardware on your computer, then click Start Setup. While setup completes, you’re shown a display of what XP Mode does and how to use it. XP Mode launches and you can now begin using it to run older applications that are not compatible with Windows 7. Conclusion This is a welcome news for many who want the ability to use XP Mode but didn’t have the proper hardware to do it. The bad news is users of Home versions of Windows still don’t get to enjoy the XP Mode feature officially. However, we have an article that shows a great workaround – Create an XP Mode for Windows 7 Home Versions & Vista.

  • Sorry about the wait.

    - by Ratman21
    In the last two days have been trying remove “Iolo System Mechanic Professional” (With anti-virus and FireWall) from 3 of the 5 pc’s we have (3 lap tops and two Desk tops) as it was going to expire on the 13th.   So I could replace them with a free anti-virus (AVG) and just use the windows fire wall. I have been using the same set up on one of my desk tops (XP Pro) for 8 months and one of the Lap tops (Vista) for 5 months.   The problem was that System Mechanic did not want to go. Even after using the uninstall option on the desk top (my main PC, well its that because has the larger of all the PC’s hard drives but, is the oldest and runs XP home) and using Ccleaner to try and remove it.  It was still showing up as there and after I went a head and tried installing AVG and ran it. I found that the TCP/IP module was missing.  So no internet, I had to restore the PC back to the 1st to get the module back and then install AVG (after making sure window firewall was back on. I didn’t check that on the first try). Got the PC back to normal, very late last night. Only one of the two lap tops was easy but, even at that there are still some parts of System Mechanic on it but, AVG and firewall are working.   I may try an hunt down parts of System Mechanic on it and delete them on this lap top. Which was what finally had to do on the one of the Lap tops (also XP Home) as it would not uninstall after I restored the PC back to the 4th. So delete, delete, delete and Ccleaner (one dl file would not delete though). And I just finish installing AVG and now running a scan on the lap top. So all of this took two days (well three counting today). I started late Friday night and just finishing up now.   I only started this switch over after I had finished my Job search for day on Friday.   As for blogging on Tuesday, Wednesday and Thursday, I was busy and by the end of the day was too tired to blog, that and was hung up still on that 2nd dare of The Love Dare. So I cleaned the house, while she was out of the house. I mean, I cleaned, not just vacuumed house I cleaned the kitchen counter tops and the sinks. Did the dishes and some of the laundry over two of the those days.   As to the third day of Love Dare which is “Love is not selfish” and the dare “Whatever you put your time, energy, and money into will become more important to you. It’s hard to care for something you are not investing in. Along with restraining from negative comments, buy your spouse something that says, I was thinking of you today.”   Being on a very limited income, a lot of normal guy buying for girls is out (for one thing, the comment why did you waste our money on flowers, etc, etc, would come up. Not from me though). So that one is on hold till money issues are not a problem (no that does not mean never). The 4th day “Love is thoughtful” and the dare “Contact your spouse sometime during the business of the day. Have no agenda other than asking how he or she is doing and if there is anything you could do for them”.   I did this dare while I was still working with census last week and trying to do the dares. Well I start my CCNA classes Monday the 15th and I move on to the next Love Dare day “Love is not rude”.

  • Mutation Problem - Clojure

    - by Silanglaya Valerio
    having trouble changing an element of my function represented as a list. code for random function: (defn makerandomtree-10 [pc maxdepth maxwidth fpx ppx] (if-let [output (if (and (< (rand) fpx) (> maxdepth 0)) (let [head (nth operations (rand-int (count operations))) children (doall (loop[function (list) width maxwidth] (if (pos? width) (recur (concat function (list (makerandomtree-10 pc (dec maxdepth) (+ 2 (rand-int (- maxwidth 1))) fpx ppx))) (dec width)) function)))] (concat (list head) children)) (if (and (< (rand) ppx) (>= pc 0)) (nth parameters (rand-int (count parameters))) (rand-int 100)))] output )) I will provide also a mutation function, which is still not good enough. I need to be able to eval my statement, so the following is still insufficient. (defn mutate-5 "chooses a node changes that" [function pc maxwidth pchange] (if (< (rand) pchange) (let [output (makerandomtree-10 pc 3 maxwidth 0.5 0.6)] (if (seq? output) output (list output))) ;mutate the children of root ;declare an empty accumulator list, with root as its head (let [head (list (first function)) children (loop [acc(list) walker (next function)] (println "----------") (println walker) (println "-----ACC-----") (println acc) (if (not walker) acc (if (or (seq?

  • cannot receive UDP broadcast packets

    - by user292792
    Hello I have 2 boxes: - an embedded device (ARM Omap with linux) which I'll call "Omap". - a PC (can either be Windows or linux). Scenario 1 Both boxes are in the same network (example: my office). The Omap gets its address from a DHCP server (ex: 192.168.10.110). The PC has always the same address (ex. 192.168.10.104). I can successfully exchange UDP broadcast packets on any port. Success. Scenario 2 The 2 boxes are in a network withOUT a DHCP server. The PC has a static IP address (example: 10.10.10.20). The Omap boots, looks for a DHCP server, doesn't find it, and is in what I call "bad IP address" state. Now... Broadcasting UDP packets from the Omap works: the PC can see them. The opposite doesn't work: UDP packets broadcasted by the PC are not seen by the Omap. I am using Wireshark on another PC to verify that the packets are being sent. Failure. I tried to change the Omap ip address (with ifconfig)... no luck. What am I missing? To complete the picture, when the Omap is in Scenario 2, if I run udhcpc ... it can communicate with the DHCP server and get an IP address. I also see the packets with Wireshark. So this means that the DHCP client is able to broadcast UDP packets. (Yes, I tried to use DHCP ports 67/68 but it doesn't work). I am using Boost C++ Asio UDP sockets. Specifically, I took the multicast examples and changed them to do broadcasting. Any help is appreciated. Thanks, Benedetto

  • C++ reference variables

    I have these two functions (with Point2D & LineVector (has 2 Point2D member variables) classes and SQUARE macro predefined) inline float distance(const Point2D &p1,const Point2D &p2) { return sqrt(SQUARE(p2.getX()-p1.getX())+SQUARE(p2.getY()-p1.getY())); } inline float maxDistance(const LineVector &lv1,const LineVector &lv2) { return max(distance(lv1.p1,lv2.p2),distance(lv1.p2,lv2.p1)); } but it gives compilation error in maxDistance() function (line 238) saying: /usr/lib/gcc/i686-pc-cygwin/3.4.4/include/c++/bits/stl_iterator_base_types.h: In instantiation of `std::iterator_traits<Point2D>': quadrilateral.cpp:238: instantiated from here /usr/lib/gcc/i686-pc-cygwin/3.4.4/include/c++/bits/stl_iterator_base_types.h:129: error: no type named `iterator_category' in `class Point2D' /usr/lib/gcc/i686-pc-cygwin/3.4.4/include/c++/bits/stl_iterator_base_types.h:130: error: no type named `value_type' in `class Point2D ' /usr/lib/gcc/i686-pc-cygwin/3.4.4/include/c++/bits/stl_iterator_base_types.h:131: error: no type named `difference_type' in `class Point2D' /usr/lib/gcc/i686-pc-cygwin/3.4.4/include/c++/bits/stl_iterator_base_types.h:132: error: no type named `pointer' in `class Point2D' /usr/lib/gcc/i686-pc-cygwin/3.4.4/include/c++/bits/stl_iterator_base_types.h:133: error: no type named `reference' in `class Point2D' Please suggest what is the error?

  • NHibernate: Using value tables for optimization AND dynamic join

    - by Kostya
    Hi all, My situation is next: there are to entities with many-to-many relation, f.e. Products and Categories. Also, categories has hierachial structure, like a tree. There is need to select all products that depends to some concrete category with all its childs (branch). So, I use following sql statement to do that: SELECT * FROM Products p WHERE p.ID IN ( SELECT DISTINCT pc.ProductID FROM ProductsCategories pc INNER JOIN Categories c ON c.ID = pc.CategoryID WHERE c.TLeft >= 1 AND c.TRight <= 33378 ) But with big set of data this query executes very long and I found some solution to optimize it, look at here: DECLARE @CatProducts TABLE ( ProductID int NOT NULL ) INSERT INTO @CatProducts SELECT DISTINCT pc.ProductID FROM ProductsCategories pc INNER JOIN Categories c ON c.ID = pc.CategoryID WHERE c.TLeft >= 1 AND c.TRight <= 33378 SELECT * FROM Products p INNER JOIN @CatProducts cp ON cp.ProductID = p.ID This query executes very fast but I don't know how to do that with NHIbernate. Note, that I need use only ICriteria because of dynamic filtering\ordering. If some one knows a solution for that, it will be fantastic. But I'll pleasure to any suggestions of course. Thank you ahead, Kostya

  • Add a Sleep Timer to Windows 7 Media Center

    - by DigitalGeekery
    Do you make it a habit of falling asleep at night while watching Windows Media Center? Today we are going to take a look at the MC7 Sleep Timer for Windows 7 Media Center. This simple little plugin allows you to schedule an automatic shutdown time in Media Center. Note: At this point MC7 Sleep Timer doesn’t work with extenders. If you’re using ClamAV or Panda it may detect this plugin as a virus, we’ve tested it and this is a false positive for these two antivirus apps. Installation and Usage Download and install MC7 Sleep Timer. (See download below) After the installation is finished, you will find MC7 Sleep Timer located in the Media Center Extras Library. Click on the tile to open the timer and configure your settings. The MC7 Sleep Timer will open in full screen mode. You can choose to shutdown the PC after 30 or 60 minutes, create a custom length shutdown timer at any 5 minute interval, or select the exact time you want the PC to shutdown.  After setting your PC to shutdown, you’ll get an audio confirmation. To set a custom timer length, scroll to the “Custom timer” option and click right or left on your Media Center remote or, the right or left arrow keys, to choose how many minutes before shutdown. To schedule a shutdown for a certain time, browse to the “Shutdown at time” button, and scroll right or left with the arrow keys on the keyboard or remote. When you’ve chosen your time, hit “Enter” on the keyboard or “OK” on the remote.   Clicking the “Monitor Off” button will turn off only the monitor and “Cancel Timer” will cancel your shutdown request. Conclusion If you often find yourself falling asleep every night watching Media Center and then fumbling and stumbling in the middle of the night to shutdown your computer, MC7 Sleep timer might just be a perfect addition to your Media Center setup.

  • DIY Sunrise Alarm Clock Sports a Polished Build and Perfect Time Keeping

    - by Jason Fitzpatrick
    We’ve seen our fair share of sunrise simulators, but by far this one is the most polished build–everything from the atomic clock circuit to the LEDs are all packed cleanly in a frosted acrylic case. Renaud Schleck, the tinker behind the build, describes the guts: This is an alarm clock simulating the sunrise, which means that a few minutes before the alarm goes off, it shines some light whose brightness increases over time. The alarm clock is built around a MSP430G2553 microcontroller compatible with the MSP430 Launchpad from Texas Instrument. It features a DCF77 module which sets the clock automatically through radio waves.

  • Good Atom Based Tablets that run Ubuntu?

    - by Anthony Papillion
    I'm starting a software project for a company that will deploy on tablet computers. They want to stick with Intel processors so they are looking for a good tablet that runs on an Atom processor. MY requirement is that it needs to also be able to run Ubuntu. It doesn't have to come with Ubuntu, I just need to be able to install it with no hassle. But, if it comes with Ubuntu preinstalled, that's even better. Can anyone make a recommend? Thanks! Anthony

  • Can Ubuntu create a semi-transparent subtitle player for accessibility?

    - by Tyler
    I've asked this in Reddit.com/r/Ubuntu in here. I've tried to get the Subtitle Player linked here to work and it have failed on Wine. So I'm curious if Ubuntu community would be willing to try and build a simple transparent subtitle player for better accessibility on Flash Player, Netflix, or even in movie theaters? Currently, I'm watching movies/videos with an Android Tablet that runs on a blank black video for 3 hours with a subtitle overlay on it so I can enjoy movie and so forth, but it requires a bit of effort and it definitely isn't for everyone. (People will have to look at the subtitle playing tablet and the movie back and forth at 60 degrees angle, while a transparent subtitle player would reduce it to 5 degrees angle to watch the movie.) Please and thank you.

  • Is there an alternative to the default lock-screen?

    - by cheshirekow
    I have a tablet PC that I'm running oneric on. One thing I don't like is that the default lock screen requires you to enter a password. Since this is a tablet, this means that it either needs to be connected to a keyboard, or I have to figure out how to get onboard to show up for the lock screen (caribou wont even start, and gok is messed up too). Even if I could do that, anyway, it's not what I want, since locking the screen is mostly to prevent erroneous input when I'm carrying it around (not for security). Are there any alternative applications for the lock screen? Anything like the plethora of android lock screens that allow you to solve puzzles or push a particular widget in a particular way to unlock the screen?

  • Easy Scaling in XAML (WPF)

    - by Robert May
    Ran into a problem that needed solving that was kind of fun.  I’m not a XAML guru, and I’m sure there are better solutions, but I thought I’d share mine. The problem was this:  Our designer had, appropriately, designed the system for a 1920 x 1080 screen resolution.  This is for a full screen, touch screen device (think Kiosk), which has that resolution, but we also wanted to demo the device on a tablet (currently using the AWESOME Samsung tablet given out at Microsoft Build).  When you’d run it on that tablet, things were ugly because it was at a lower resolution than the target device. Enter scaling.  I did some research and found out that I probably just need to monkey with the LayoutTransform of some grid somewhere.  This project is using MVVM and has a navigation container that we built that lives on a single root view.  User controls are then loaded into that view as navigation occurs. In the parent grid of the root view, I added the following XAML: <Grid.LayoutTransform> <ScaleTransform ScaleX="{Binding ScaleWidth}" ScaleY="{Binding ScaleHeight}" /> </Grid.LayoutTransform> And then in the root View Model, I added the following code: /// <summary> /// The required design width /// </summary> private const double RequiredWidth = 1920; /// <summary> /// The required design height /// </summary> private const double RequiredHeight = 1080; /// <summary>Gets the ActualHeight</summary> public double ActualHeight { get { return this.View.ActualHeight; } } /// <summary>Gets the ActualWidth</summary> public double ActualWidth { get { return this.View.ActualWidth; } } /// <summary> /// Gets the scale for the height. /// </summary> public double ScaleHeight { get { return this.ActualHeight / RequiredHeight; } } /// <summary> /// Gets the scale for the width. /// </summary> public double ScaleWidth { get { return this.ActualWidth / RequiredWidth; } } Note that View.ActualWidth and View.ActualHeight are just pointing directly at FrameworkElement.ActualWidth and FrameworkElement.ActualHeight. That’s it.  Just calculate the ratio and bind the scale transform to it. Hopefully you’ll find this useful. Technorati Tags: WPF,XAML
