  • Convert Markdown text to RTF, using Ruby and Pandoc?

    - by niteshade
    Playing with Ruby and Ruby-Pandoc. Seems like a nice tool, if I can get it to work. I'd like to convert some Markdown text (with embedded lists and other fanciness) to Rich Text. Here's the text I'm converting: Title === This is a paragraph. Hallelujah. Here comes a nested list. --- * List item 1 * List item 1.1 * List item 1.2 * List item 2 * List item 2.1 Here's my Ruby code... require 'pandoc-ruby' input = File.read(test.md) converter = PandocRuby.new(input, from: :markdown, to: :rtf) puts converter.convert ... which (after saving the output to a file) produces a document without anything but a title: Here's the code of the RTF file: {\pard \ql \f0 \sa180 \li0 \fi0 \b \fs36 Title\par} {\pard \ql \f0 \sa180 \li0 \fi0 This is a paragraph. Hallelujah.\par} {\pard \ql \f0 \sa180 \li0 \fi0 \b \fs32 Here comes a nested list.\par} {\pard \ql \f0 \sa0 \li360 \fi-360 \bullet \tx360\tab List item 1\par} {\pard \ql \f0 \sa0 \li360 \fi-360 \bullet \tx360\tab List item 1.1\par} {\pard \ql \f0 \sa0 \li360 \fi-360 \bullet \tx360\tab List item 1.2\par} {\pard \ql \f0 \sa0 \li360 \fi-360 \bullet \tx360\tab List item 2\par} {\pard \ql \f0 \sa0 \li360 \fi-360 \bullet \tx360\tab List item 2.1\sa180\par} In addition, even if it did show up in my RTF viewer (Mac TextEdit), the RTF code seems to have lost all list nesting. I don't know how to diagnose this, whether I have not stated necessary header information or something in Ruby-Pandoc. Thanks in advance!

  • Custom PHP Framework Feedback

    - by Jascha
    I've been learning OOP programming for about a year and a half now and have developed a fairly standard framework to which I generally abide by. I'd love some feedback or input on how I might improve some functionality or if there are some things I'm overlooking. VIEW MODE 1) Essentially everything starts at the Index.php page. The first thing I do is require my "packages.php" file that is basically a config file that imports all of the classes and function lists I'll be using. 2) I have no direct communication between my index.php file and my classes, what I've done is "pretty them up" with my viewfunctions.php file which is essentially just a conduit to the classes so that in my html I can write <?php get_title('page'); ?> instead of <?php echo $pageClass->get_title('page'); ?> Plus, I can run a couple small booleans and what not in the view function script that can better tailor the output of the class. 3) Any information brought in via the database is started from it's corresponding class that has direct communication with the database class, the only class that is allowed direct to communicate with the database (allowed in the sense that I run all of my queries with custom class code). INPUT MODE 1) Any user input is sent to my userFunctions.php. 2) My security class is then instantiated where I send whatever user input that has been posted for verification and validation. 3) If the input passes my security check, I then pass it to my DB class for input into my Database. FEEDBACK I'm wondering if there are any glaringly obvious pitfalls to the general structure, or ways I can improve this. Thank you in advance for your input. I know there is real no "right" answer for this, but I imagine a couple up votes would be in order for some strong advice regarding building frameworks. -J

  • Expose webservice directly to webclients or keep a thin server-side script layer in between?

    - by max
    Hi, I'm developing a REST webservice (Java, Jersey). The people I'm doing this for want to directly access the webservice via Javascript. Some instinct tells me this is not a good idea, but I cannot really explain that instinct. My natural approach would have been to have the webservice do the real logic and database access, but also have some (relatively thin) server-side script layer (e.g. in PHP). Clients would talk to the PHP layer which in turn would talk to the webservice. (The webservice would be pretty local to the apache/PHP server and implicitly trust calls from the script layer. The script layer would take care of session management.) (Btw, I am not talking about just hiding the webservice behind an Apache which simply redirects calls.) But as I find myself at a lack of words/arguments to explain my instinct, I wonder whether my instinct is right - note that while I have been developing all kinds of software in all kinds of languages and frameworks for like 17 years, this is the first time I develop a webservice. So my question is basically: what are your opinions? Are there any standard setups? Is my instinct totally wrong? Or partially? ;P Many thanks, Max PS: I might add a few bits of information about the planned usage of the whole application: will be accessed by different kinds of users, partly general public, partly privileged thus, all major OS/browser combinations can be expected as clients however, writing the client is not my responsibility will potentially have very high load/traffic logic of webservice will later be massively expanded for another product which is basically a superset of the functionality of the current project there is a significant likelihood that at some point an API should be exposed which can be used by 3rd party developers - obviously, with some restrictions at some point, the public view of the product should become accessible via smartphones, too (in other words, maybe a customized version of the site to adapt to the smaller display and different input methods)

  • C++ Serial Port Only Responding Once Using Write()

    - by Pfeffer
    All the code below works. My device responds, C,7 is a reset. When I run this the second time it doesn't respond. If I manually turn my device off and on, then run this script again it works. But not if I press the button to run the script the second time. RS232: 57600,8,N,1 Any ideas?? Is there any more information needed to solve this? *Also when I get this working I'm going to have to use the read() function to get the devices responses. Does anyone know the correct format I need to use, based on the below code? Sorry I'm new to C++...I'm more of a PHP guy. *I also don't know if 1024 is right, but it seems to work so eh... Thanks so much! #include <termios.h> int fd; struct termios options; fd=open("/dev/tty.KeySerial1", O_RDWR | O_NOCTTY | O_NDELAY); fcntl(fd, F_SETFL, 0); tcgetattr(fd,&options); options.c_ispeed=57600; options.c_ospeed=57600; options.c_cflag |= (CLOCAL | CREAD); options.c_lflag &= ~(ICANON | ECHO | ECHOE | ISIG); options.c_cflag &= ~CSTOPB; options.c_lflag &= ~ECHO; options.c_oflag &= ~ECHO; options.c_oflag &= ~OPOST; options.c_cflag |= CS8; options.c_cflag |= CRTSCTS; options.c_cc[VMIN] = 0; options.c_cc[VTIME] =10; tcflush(fd, TCIFLUSH); tcsetattr(fd,TCSANOW,&options); write(fd, "C,7\r\n", 1024); close(fd);

  • How do I use cookies to store users' recent site history(PHP)?

    - by ggfan
    I decided to make a recent view box that allows users to see what links they clicked on before. Whenever they click on a posting, the posting's id gets stored in a cookie and displays it in the recent view box. In my ad.php, I have a definerecentview function that stores the posting's id (so I can call it later when trying to get the posting's information such as title, price from the database) in a cookie. How do I create a cookie array for this? **EXAMPLE:** user clicks on ad.php?posting_id='200' //this is in the ad.php function definerecentview() { $posting_id=$_GET['posting_id']; //this adds 30 days to the current time $Month = 2592000 + time(); $i=1; if (isset($posting_id)){ //lost here for($i=1,$i< ???,$i++){ setcookie("recentviewitem[$i]", $posting_id, $Month); } } } function displayrecentviews() { echo "<div class='recentviews'>"; echo "Recent Views"; if (isset($_COOKIE['recentviewitem'])) { foreach ($_COOKIE['recentviewitem'] as $name => $value) { echo "$name : $value <br />\n"; //right now just shows the posting_id } } echo "</div>"; } How do I use a for loop or foreach loop to make it that whenever a user clicks on an ad, it makes an array in the cookie? So it would be like.. 1. clicks on ad.php?posting_id=200 --- setcookie("recentviewitem[1]",200,$month); 2. clicks on ad.php?posting_id=201 --- setcookie("recentviewitem[2]",201,$month); 3. clicks on ad.php?posting_id=202 --- setcookie("recentviewitem[3]",202,$month); Then in the displayrecentitem function, I just echo however many cookies were set? I'm just totally lost in creating a for loop that sets the cookies. any help would be appreciated

  • Stopping Filter Display in Dynamic Data Entity Web App

    - by bert
    I'm currently experimenting with the Dynamic Data Entity Web App Project type in VS2008 SP1 and after reading many tutorials which offer helpful advice for problems I so far have no need of a solution to I have fallen at the first hurdle. In the DB I have made my entity model from I decided to start small with a table called "Companies" just to see if I could tweak the display into a satisfactory shape for this small table. The Companies table has a column called "contactid" which leads to a record filled with various contact information in a "contacts" table. The default created Entity Data Model has guessed that One companies could have many contact records. So it tries to be helpful and add a "Contact" filter onto the page that allows you to see all the Companies that share a particular set of contact info indexed by the "Contact Name" field. Unfortunately the contact table is a multi-purpose one that also stores contact info for customers and there are about 1000 times more customers than there are companies. So the Dropdown makes the page load time increase exponentially and produces no benefit. So I'd like to just stop the filter from appearing. Only problem is I don't have a clue how to switch it off. Google is so far proving recalcitrant on the matter so I wondered if anyone in here knew how to get rid of a useless filter.

  • Javascript Regex: Testing string for intelligent query

    - by Shyam
    Hi, I have a string that holds user input. This string can contain various types of data, like: a six digit id a zipcode that contains out of 4 digits and two alphanumeric characters a name (characters only) As I am using this string to search through a database, the query type is determined on the type of search, which i want to handle serverside using JavaScript (yes, I am using JavaScript serverside). Searching on StackOverflow, brought me some interesting information, like the .test-method, which seems perfect for my needs. The test-method returns either true or false based on the evaluation on the string using a regex object. I am using this page as a reference: http://www.javascriptkit.com/jsref/regexp.shtml So I am trying to determine the zipcode, by using the following very noobish regex. var r = /[A-Za-z]{2,2}/ As far I can understand, this should limit the amount of occurrences of alphanumeric characters to a maximum of two. See beneath the output of my JavaScript console. > var r = /[A-Za-z]{2,2}/ > var x = "2233AL" > r.test(x) true > var x = "2233A" > r.test(x) false > var x = "2233ALL" > r.test(x) true /* i want this to be false */ > A little help would be really appreciated!

  • JavaScript array random index insertion and deletion

    - by Tomi
    I'm inserting some items into array with randomly created indexes, for example like this: var myArray = new Array(); myArray[123] = "foo"; myArray[456] = "bar"; myArray[789] = "baz"; ... In other words array indexes do not start with zero and there will be "numeric gaps" between them. My questions are: Will these numeric gaps be somehow allocated (and therefore take some memory) even when they do not have assigned values? When I delete myArray[456] from upper example, would items below this item be relocated? EDIT: Regarding my question/concern about relocation of items after insertion/deletion - I want to know what happens with the memory and not indexes. More information from wikipedia article: Linked lists have several advantages over dynamic arrays. Insertion of an element at a specific point of a list is a constant-time operation, whereas insertion in a dynamic array at random locations will require moving half of the elements on average, and all the elements in the worst case. While one can "delete" an element from an array in constant time by somehow marking its slot as "vacant", this causes fragmentation that impedes the performance of iteration.

  • How to check the correct radio button.

    - by MrW
    I have a Table containing some information that I need. All these rows also contains a column with a radio button in it so that the user is suppose to be able to check one of the rows as default. When I'm bringing the data back from the DB and want to select the one that's currentlly the default one. <% foreach (var item in (IEnumerable<Locale>) ViewData["Locales"]) { %> <tr> <td> <%= Html.Encode(item.Language.Name) %> </td> <td> <input type="radio" id="defaultLocale" name="defaultLocele" value="on" checked="<%= item.Default == false ? "false" : "true" %>" /> </td> I've also tried to do this: <input type="radio" id="defaultLocale" name="defaultLocele" value="on" checked="<%=item.Default == false ? "" : "checked" %>" /> but nothing seems to do the right thing. I always end up with having the last row in checked, which it isn't for sure.

  • sending large data .getJSON or proxy ?

    - by numerical25
    Hey guys. I was told that the only trick to sending data to a external server (i.e x-domain) is to use getJSON. Well my problem is that the data I am sending exceeds the getJSON data limit. I am tracking mouse movements on a screen for analytics. Another option is I could also send a little data at a time. probably every time the mouse moves. but that seems as if it would slow things down. I could setup a proxy server. My question is which would be better? Setting up a proxy server ? or Just sending bits of information via javascript or JQUERY. What do the professionals use (Google and other company's that build mash-ups that send a lot of data to x-domain sites.) I need to know the best practices. Thanx!! Also the data is put into JSON.

  • How to create a desktop shortcut to a website with website logo as icon?

    - by Wbdvlpr
    Hi I need a solution which allows users to create a desktop shortcut to a website, preferably with website logo as shortcut icon. There are ways users can create shortcut such as drag drop favicon or right click create new shortcut etc. This works but also creates the shortcut with default IE icon on windows. I am trying to avoid this method for this icon and some other reasons. I thought of creating a website-title.URL file, and tell users to download and save file to their desktop, again this works but doesn't solve the icon problem as the website logo (.ico) has to be at local disk and at a pre-specified location [IconFile=path]. I was wondering if it is possible to create a some sort of installer or windows application which users can download from the website. Once its executed by user, it creates this .URL file on user desktop which have IconFile path pre-specified, and copy the website-logo.ico at path specified in .URL file etc. So my questions are - Is it possible to create such a solution? What programming languages can be used to achieve this? Can this installer/app be made to work on non-windows machines as well? From developments point of view how big project it is? if I have to hire a programmer to do this. Please let me know if you need more information. Thanks

  • updating a column in a table only if after the update it won't be negative and identifying all updat

    - by Azeem
    Hello all, I need some help with a SQL query. Here is what I need to do. I'm lost on a few aspects as outlined below. I've four relevant tables: Table A has the price per unit for all resources. I can look up the price using a resource id. Table B has the funds available to a given user. Table C has the resource production information for a given user (including the number of units to produce everyday). Table D has the number of units ever produced by any given user (can be identified by user id and resource id) Having said that, I need to run a batch job on a nightly basis to do the following: a. for all users, identify whether they have the funds needed to produce the number of resources specified in table C and deduct the funds if they are available from table B (calculating the cost using table A). b. start the process to produce resources and after the resource production is complete, update table D using values from table C after the resource product is complete. I figured the second part can be done by using an UPDATE with a subquery. However, I'm not sure how I should go about doing part a. I can only think of using a cursor to fetch each row, examine and update. Is there a single sql statement that will help me avoid having to process each row manually? Additionally, if any rows weren't updated, the part b. SQL should not produce resources for that user. Basically, I'm attempting to modify the sql being used for this logic that currently is in a stored procedure to something that will run a lot faster (and won't process each row separately). Please let me know any ideas and thoughts. Thanks! - Azeem

  • Design patterns for Caching Images in a MVC?

    - by Onema
    Hi, I'm designing an image cache system that will be used in an MVC CMS. The main purpose of the image cacher is to modify images: scale, crop, etc and cache them in the client site. I have created an image cache Model and Mapper that interact with the Database, to keep track of the images and know what kind of actions have been applied to them (scale, crop, etc). In addition to the Model and Mapper I have created a ImageCacher Class that is used by the API to manage the Model and image creation based on arguments passed by the client site, this class creates the images and generates the links to the images for the View. A coworker argued that I need to include the functionality of this last Class inside the Model, as the bulk of the logic should go in the model. I respectfully disagree with him since I feel the model's responsibility is to deal with the information about the images cached at the database level, and the responsibility of the ImageCacher Class is to create the url/image that we will be caching (keeping the single responsibility principle). In addition to this I believe that a model should not have Presentation-related features, like creating or showing images. Does anyone have any insight on this? is there a particular design pattern that would make this division of tasks clear and and the image cacher reusable? Should I add all the logic in the Model? Thank you.

  • How to iterate properly across a const set?

    - by Jared
    I'm working on a program that's supposed to represent a graph. My issue is in my printAdjacencyList function. Basically, I have a Graph ADT that has a member variable "nodes", which is a map of the nodes of that graph. Each Node has a set of Edge* to the edges it is connected to. I'm trying to iterate across each node in the graph and each edge of a node. void MyGraph::printAdjacencyList() { std::map<std::string, MyNode*>::iterator mit; std::set<MyEdge*>::iterator sit; for (mit = nodes.begin(); mit != nodes.end(); mit++ ) { std::cout << mit->first << ": {"; const std::set<MyEdge*> edges = mit->second->getEdges(); for (sit = edges.begin(); sit != edges.end(); sit++) { std::pair<MyNode*, MyNode*> edgeNodes = *sit->getEndpoints(); } } std::cout << " }" << std::endl; } getEdges is declared as: const std::set<MyEdge*>& getEdges() { return edges; }; and get Endpoints is declared as: const std::pair<MyNode*, MyNode*>& getEndpoints() { return nodes; }; The compiler error I'm getting is: MyGraph.cpp:63: error: request for member `getEndpoints' in `*(&sit)->std::_Rb_tree_const_iterator<_Tp>::operator-> [with _Tp = MyEdge*]()', which is of non-class type `MyEdge* const' MyGraph.cpp:63: warning: unused variable 'edgeNodes' I have figured out that this probably means I'm misusing const somewhere, but I can't figure out where for the life of me. Any information would be appreciated. Thanks!

  • rendering a TextView in a Bitmap for an android widget

    - by foke
    I'm building a widget which displays some text. By widget I mean the kind which lies on the desktop. The problem is that I want to change text's font at runtime. There is several textview I would like, at runtime, to set the first as bold, the second blue and italic for example, etc. I came up with this : TextView tv = new TextView(context); tv.setText(stringToDisplay); tv.setTextColor(0xa00050ff); // example tv.setTextSize(30); // example Bitmap b = loadBitmapFromView(tv); updateViews.setImageViewBitmap(R.id.id_of_the_imageview, b); with private static Bitmap loadBitmapFromView(View v) { Bitmap b = Bitmap.createBitmap(v.getLayoutParams().width, v.getLayoutParams().height, Bitmap.Config.ARGB_8888); Canvas c = new Canvas(b); v.layout(0, 0, v.getLayoutParams().width, v.getLayoutParams().height); v.draw(c); return b; } but it wont work (NullPointerException on first line of loadBitmap), until I replace v.getLayoutParams().width, v.getLayoutParams().height by fixed sizes like 250, 50 Bitmap b = Bitmap.createBitmap(250, 50, Bitmap.Config.ARGB_8888); // ... v.layout(0, 0, 250, 50); But that's not a good solution ... so I tried this : LayoutInflater li = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); View row = li.inflate(R.layout.widget_text, null); TextView tv = (TextView) row.findViewById(R.id.id_of_the_textview); widget_text being a layout similar to the displayed one but with TextViews instead of ImageViews, in the hope to get some size information out of it .. but it's not working and I get this exception : 01-02 17:35:06.001: ERROR/AndroidRuntime(11025): Caused by: java.lang.IllegalArgumentException: width and height must be > 0 on the call to Bitmap.createBitmap() so, someone could point me in the right direction?

  • How to query an .NET assembly's required framework (not CLR) version?

    - by Bonfire Burns
    Hi, we are using some kind of plug-in architecture in one of our products (based on .NET). We have to consider our customers or even 3rd party devs writing plug-ins for the product. The plug-ins will be .NET assemblies that are loaded by our product at run-time. We have no control about the quality or capabilities of the external plug-ins (apart from checking whether they implement the correct interfaces). So we need to implement some kind of safety check while loading the plug-ins to make sure that our product (and the hosting environment) can actually host the plug-in or deliver a meaningful error message ("The plug-in your are loading needs .NET version 42.42 - the hosting system is only on version 33.33."). Ideally the plug-ins would do this check internally, but our experience regarding their competence is so-so and in any case our product will get the blame, so we want to make sure that this "just works". Requiring the plug-in developers to provide the info in the metadata or to explicitly provide the information in the interface is considered "too complicated". I know about the Assembly.ImageRuntimeVersion property. But to my knowledge this tells me only the needed CLR version, not the framework version. And I don't want to check all of the assembly's dependencies and match them against a table of "framework version vs. available assemblies". Do you have any ideas how to solve this in a simple and maintainable fashion? Thanks & regards, Bon

  • Outlook VSTO AddIn for Meetings

    - by BigDubb
    We have created a VSTO addin for Outlook Meetings. As part of this we trap on the SendEvent of the message on the FormRegionShowing event: _apptEvents.Send += new Microsoft.Office.Interop.Outlook.ItemEvents_SendEventHandler(_apptEvents_Send); The method _apptEvents_Send then tests on a couple of properties and exits where appropriate. private void _apptEvents_Send(ref bool Cancel) { if (!_Qualified) { MessageBox.Show("Meeting has not been qualified", "Not Qualified Meeting", MessageBoxButtons.OK, MessageBoxIcon.Information); chkQualified.Focus(); Cancel = true; } } The problem that we're having is that some users' messages get sent twice. Once when the meeting is sent and a second time when the user re-opens outlook. I've looked for memory leaks, thinking that something might not be getting disposed of properly, and have added explicit object disposal on all finally calls to try and make sure resources are managed, but still getting the functionality incosistently across the organization. i.e. I never encountered the problem during development, nor other developers during testing. All users are up to date on framework (3.5 SP1) and Hotfixes for Outlook. Does anyone have any ideas on what might be causing this? Any ideas anyone might have would be greatly appreciated.

  • Best Practices For Secure APIs?

    - by Ferrett Steinmetz
    Let's say I have a website that has a lot of information on our products. I'd like some of our customers (including us!) to be able to look up our products for various methods, including: 1) Pulling data from AJAX calls that return data in cool, JavaScripty-ways 2) Creating iPhone applications that use that data; 3) Having other web applications use that data for their own end. Normally, I'd just create an API and be done with it. However, this data is in fact mildly confidential - which is to say that we don't want our competitors to be able to look up all our products every morning and then automatically set their prices to undercut us. And we also want to be able to look at who might be abusing the system, so if someone's making ten million complex calls to our API a day and bogging down our server, we can cut them off. My next logical step would be then to create a developers' key to restrict access - which would work fine for web apps, but not so much for any AJAX calls. (As I see it, they'd need to provide the key in the JavaScript, which is in plaintext and easily seen, and hence there's actually no security at all. Particularly if we'd be using our own developers' keys on our site to make these AJAX calls.) So my question: after looking around at Oauth and OpenID for some time, I'm not sure there is a solution that would handle all three of the above. Is there some sort of canonical "best practices" for developers' keys, or can Oauth and OpenID handle AJAX calls easily in some fashion I have yet to grok, or am I missing something entirely?

  • Using a CNAME with Shared Windows Azure Website

    - by user1679021
    I've been following instructions on the Azure site to add a CNAME to point to my Azure website. I have had some problems getting it to work and there seems to be some contradictory information in some of the posts. I have my website running in "Shared" mode, which according to the Azure instructions supports custom domains and indeed it seems to allow me to manage domains. But some posts seem to indicate that I have to run in reserved mode. Can anyone confirm this? Also, some posts seem to indicate that I need to add the CNAME in the Azure management portal, but I cannot find where this is. Any help appreciated? I don't really understand A records and CNAME that well. My DNS provider allows me to add both. Do I need to change both? Currently my A record points the "root" to the IP address that Azure gives me and the CNAME points www.mydomain to the Azure website host mysite.azurewebsites.net. I have left them for a while to propogate and nothing seem to happen.

  • How to load/save C++ class instance (using STL containers) to disk

    - by supert
    I have a C++ class representing a hierarchically organised data tree which is very large (~Gb, basically as large as I can get away with in memory). It uses an STL list to store information at each node plus iterators to other nodes. Each node has only one parent, but 0-10 children. Abstracted, it looks something like: struct node { public: node_list_iterator parent; // iterator to a single parent node double node_data_array[X]; map<int,node_list_iterator> children; // iterators to child nodes }; class strategy { private: list<node> tree; // hierarchically linked list of nodes struct some_other_data; public: void build(); // build the tree void save(); // save the tree from disk void load(); // load the tree from disk void use(); // use the tree }; I would like to implement the load() and save() to disk, and it should be fairly fast, however the obvious problems are: I don't know the size in advance; The data contains iterators, which are volatile; My ignorance of C++ is prodigious. Could anyone suggest a pure C++ solution please?
