  • jQuery Templates on Microsoft Ajax CDN

    - by Stephen Walther
    The beta version of the jQuery Templates plugin is now hosted on the Microsoft Ajax CDN. You can start using the jQuery Templates plugin in your application by referencing both jQuery 1.4.2 and jQuery Templates from the CDN. Here are the two script tags that you will want to use when developing an application: <script type="text/javascript" src=”http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.js”></script> <script type="text/javascript" src=”http://ajax.microsoft.com/ajax/jquery.templates/beta1/jquery.tmpl.js”></script> In addition, minified versions of both files are available from the CDN: <script type="text/javascript" src="http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.min.js"></script> <script type="text/javascript" src="http://ajax.microsoft.com/ajax/jquery.templates/beta1/jquery.tmpl.min.js"></script> Here’s a full code sample of using jQuery Templates from the CDN to display pictures of cats from Flickr: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Cats</title> <style type="text/css"> html { background-color:Orange; } #catBox div { width:250px; height:250px; border:solid 1px black; background-color:White; margin:5px; padding:5px; float:left; } #catBox img { width:200px; height: 200px; } </style> </head> <body> <h1>Cat Photos!</h1> <div id="catBox"></div> <script type="text/javascript" src="http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.min.js"></script> <script type="text/javascript" src="http://ajax.microsoft.com/ajax/jquery.templates/beta1/jquery.tmpl.min.js"></script> <script id="catTemplate" type="text/x-jquery-tmpl"> <div> <b>${title}</b> <br /> <img src="${media.m}" /> </div> </script> <script type="text/javascript"> var url = "http://api.flickr.com/services/feeds/groups_pool.gne?id=44124373027@N01&lang=en-us&format=json&jsoncallback=?"; // Grab some flickr images of cats $.getJSON(url, function (data) { // Format the data using the catTemplate template $("#catTemplate").tmpl(data.items).appendTo("#catBox"); }); </script> </body> </html> This page displays a list of cats retrieved from Flickr: Notice that the cat pictures are retrieved and rendered with just a few lines of code: var url = "http://api.flickr.com/services/feeds/groups_pool.gne?id=44124373027@N01&lang=en-us&format=json&jsoncallback=?"; // Grab some flickr images of cats $.getJSON(url, function (data) { // Format the data using the catTemplate template $("#catTemplate").tmpl(data.items).appendTo("#catBox"); }); The final line of code, the one that calls the tmpl() method, uses the Templates plugin to render the cat photos in a template named catTemplate. The catTemplate template is contained within a SCRIPT element with type="text/x-jquery-tmpl". The jQuery Templates plugin is an “official” jQuery plugin which will be included in jQuery 1.5 (the next major release of jQuery). You can read the full documentation for the plugin at the jQuery website: http://api.jquery.com/category/plugins/templates/ The jQuery Templates plugin is still beta so we would really appreciate your feedback on the plugin. Let us know if you use the Templates plugin in your website.

  • Creating my first F# program in my new &ldquo;Expert F# Book&rdquo;

    - by MarkPearl
    So I have a brief hour or so that I can dedicate today to reading my F# book. It’s a public holiday and my wife’s birthday and I have a ton of assignments for UNISA that I need to complete – but I just had to try something in F#. So I read chapter 1 – pretty much an introduction to the rest of the book – it looks good so far. Then I get to chapter 2, called “Getting Started with F# and .NET”. Great, there is a code sample on the first page of the chapter. So I open up VS2010 and create a new F# console project and type in the code which was meant to analyze a string for duplicate words… #light let wordCount text = let words = Split [' '] text let wordset = Set.ofList words let nWords = words.Length let nDups = words.Length - wordSet.Count (nWords, nDups) let showWordCount text = let nWords,nDups = wordCount text printfn "--> %d words in text" nWords printfn "--> %d duplicate words" nDups   So… bad start - VS does not like the “Split” method. It gives me an error message “The value constructor ‘Split’ is not defined”. It also doesn’t like wordSet.Count telling me that the “namespace or module ‘wordSet’ is not defined”. ??? So a bit of googling and it turns out that there was a bit of shuffling of libraries between the CTP of F# and the Beta 2 of F#. To have access to the Split function you need to download the F# PowerPack and hen reference it in your code… I download and install the powerpack and then add the reference to FSharp.Core and FSharp.PowerPack in my project. Still no luck! Some more googling and I get the suggestions I got were something like this…#r "FSharp.PowerPack.dll";; #r "FSharp.PowerPack.Compatibility.dll";; So I add the code above to the top of my Program.fs file and still no joy… I now get an error message saying… Error    1    #r directives may only occur in F# script files (extensions .fsx or .fsscript). Either move this code to a script file, add a '-r' compiler option for this reference or delimit the directive with '#if INTERACTIVE'/'#endif'. So what does that mean? If I put the code straight into the F# interactive it works – but I want to be able to use it in a project. The C# equivalent I would think would be the “Using” keyword. The #r doesn’t seem like it should be in the FSharp code. So I try what the compiler suggests by doing the following…#if INTERACTIVE #r "FSharp.PowerPack.dll";; #r "FSharp.PowerPack.Compatibility.dll";; #endif No luck, the Split method is still not recognized. So wait a second, it mentioned something about FSharp.PowerPack.Compatibility.dll – I haven’t added this as a reference to my project so I add it and remove the two lines of #r code. Partial success – the Split method is now recognized and not underlined, but wordSet.Count is still not working. I look at my code again and it was a case error – the original wordset was mistyped comapred to the wordSet. Some case correction and the compiler is no longer complaining. So the code now seems to work… listed below…#light let wordCount text = let words = String.split [' '] text let wordSet = Set.ofList words let nWords = words.Length let nDups = words.Length - wordSet.Count (nWords, nDups) let showWordCount text = let nWords,nDups = wordCount text printfn "--> %d words in text" nWords printfn "--> %d duplicate words" nDups  So recap – if I wanted to use the interactive compiler then I need to put the #r code. In my mind this is the equivalent of me adding the the references to my project. If however I want to use the powerpack in a project – I just need to make sure that the correct references are there. I feel like a noob once again!

  • Recover Lost Form Data in Firefox

    - by Asian Angel
    Have you ever filled in a text area or form in a webpage and something happens before you can finish it? If you like the idea of recovering that lost data then you will want to have a look at the Lazarus: Form Recovery extension for Firefox. Lazarus: Form Recovery in Action For our first example we chose the comment text box area for one of the articles here at the website. As you can see we were not finished typing in the whole comment yet… Notice the “Lazarus Icon” in the lower right corner. Note: We simulated accidental tab closures for our two examples. After getting our webpage opened up again all of our text was gone. Right clicking within the text area showed two options available…”Recover Text & Recover Form”. Notice that our lost text was listed as a “sub menu”…this could be extremely useful in matching up the appropriate text to the correct webpage if you had multiple tabs open before something happened. Click on the correct text listing to insert it. So easy to finish writing our comment without having to start from zero again. In our second example we chose the sign-up form page for the website. As before we were not finished filling in the form… Getting the webpage opened back up showed the same problem as before…all the entered text was lost. This time we right clicked in the browser window area and there was that wonderful “Recover Form Command” waiting to be used. One click and… All of our lost form data was back and we were able to finish filling in the form. For those who may be interested you can disable Lazarus: Form Recovery on individual websites using the “Context Menu” for the “Status Bar Icon” Options There are three sections in the options and you should take a quick look through them to make any desired modifications in how Lazarus: Form Recovery functions. The first “Options Area” focuses on display/access for the extension. The second “Options Area” allows you to expand the type of data retained, enable removal of data within a given time frame, set up a password, disable search indexing, and enable form data retention while in “Private Browsing Mode”. The third “Options Area” focuses on the Lazarus database itself. Conclusion If you have ever lost text area or form data before then you know how much time could be lost in starting over. Lazarus: Form Recovery helps provide a nice backup solution to get you up and running once again with a minimum of effort.

  • Scripts Casing Flash Intro Animation To Stop [migrated]

    - by ubique
    When my Flash website loads, it freezes halfway through the initial animation for 2-3 seconds and then continues. This obviously doesn't look great and I can't figure out what is causing it. Am thinking it is one of the scripts in index.html causing the issue and have tried all sorts of ways to correct it - what have I done wrong? <!DOCTYPE html> <html lang="en"> <head> <title>company name</title> . . . <link href="style.css" rel="stylesheet" type="text/css" /> <script type="text/javascript" src="js/flashobject.js"></script> <!--[if lt IE 7]> <link href="ie6.css" rel="stylesheet" type="text/css" /> <![endif]--> </head> <body> <header> <hgroup> <h1>company</h1> <h2>company</h2> </hgroup> </header> <div id="container"> <div id="head"> <div class="aligncenter"><a href="http://www.adobe.com/go/EN_US-H-GET-FLASH"> <img src="http://www.adobe.com/images/shared/download_buttons/get_adobe_flash_player.png" alt="" /></a> </div> </div> </div> <div class="g-plus" data-href="https://plus.google.com/100925740920754223119?rel=publisher" data-width="170" data-height="69" data-theme="light"> </body> <!-- Flash --> <script type="text/javascript"> var fo = new FlashObject("main_v10.swf", "head", "100%", "100%", "8", ""); fo.addParam("quality", "high"); fo.addParam("allowFullScreen", "true"); fo.write("head"); </script> <!-- Hello Bar --> <script type="text/javascript" src="//www.hellobar.com/hellobar.js"></script> <script type="text/javascript"> new HelloBar(39040,52484); </script> <!-- GPlus --> <script type="text/javascript"> window.___gcfg = {lang: 'en'}; (function() {var po = document.createElement("script"); po.type = "text/javascript"; po.async = true;po.src = "https://apis.google.com/js/plusone.js"; var s = document.getElementsByTagName("script")[0]; s.parentNode.insertBefore(po, s); })();</script> <!-- Google --> <script type="text/javascript"> var _gaq = _gaq || []; _gaq.push(['_setAccount', 'UA-xxxxxxxx-1']); _gaq.push(['_setSiteSpeedSampleRate', 10]); _gaq.push(['_trackPageview']); (function init() { var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true; ga.src = ('https:' == document.location.protocol ?

  • Where to place web.xml outside WAR file for secure redirect?

    - by Silverhalide
    I am running Tomcat 7 and am deploying a bunch of applications delivered to me by a third party as WAR files. I'd like to force some of those apps to always use SSL. (All the "SSL" apps are in one service; other apps outside this discussion are in another service.) I've figured out how to use conf\web.xml to redirect apps from HTTP to HTTPS, but that applies to all applications hosted by Tomcat. I've also figured out how to put web.xml in an unpacked app's web-inf directory; that does the trick for that specific app, but runs the risk of being overwritten if our vendor gives us a new war file to deploy. I've also tried placing the web.xml file in various places under conf\service\host, or under appbase, but none seem to work. Is it possible to redirect some apps to SSL without forcing all apps to redirect, or to put the web.xml file inside the extracted WAR file? Here's my server.xml: <Service name="secure"> <Connector port="80" connectionTimeout="20000" redirectPort="443" URIEncoding="UTF-8" enableLookups="false" compression="on" protocol="org.apache.coyote.http11.Http11Protocol" compressableMimeType="text/html,text/xml,text/plain,text/javascript,application/json,text/css"/> <Connector port="443" URIEncoding="UTF-8" enableLookups="false" compression="on" protocol="org.apache.coyote.http11.Http11Protocol" compressableMimeType="text/html,text/xml,text/plain,text/javascript,application/json,text/css" scheme="https" secure="true" SSLEnabled="true" sslProtocol="TLS" keystoreFile="..." keystorePass="..." keystoreType="PKCS12" truststoreFile="..." truststorePass="..." truststoreType="JKS" clientAuth="false" ciphers="SSL_RSA_WITH_RC4_128_MD5,SSL_RSA_WITH_RC4_128_SHA,TLS_RSA_WITH_AES_128_CBC_SHA,TLS_DHE_RSA_WITH_AES_128_CBC_SHA,TLS_DHE_DSS_WITH_AES_128_CBC_SHA,SSL_RSA_WITH_AES_128_CBC_SHA"/> <Engine name="secure" defaultHost="localhost"> <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/> <Host name="localhost" appBase="webapps" unpackWARs="false" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false"> </Host> </Engine> </Service> <Service name="mutual-secure"> ... </Service> The content of the web.xml files I'm playing with is: <web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0" metadata-complete="true"> <security-constraint> <web-resource-collection> <web-resource-name>All applications</web-resource-name> <url-pattern>/*</url-pattern> </web-resource-collection> <user-data-constraint> <description>Redirect all requests to HTTPS</description> <transport-guarantee>CONFIDENTIAL</transport-guarantee> </user-data-constraint> </security-constraint> </web-app> (For conf\web.xml the security-constraint is added just before the end of the existing file, rather than create a new file.) My webapps directory (currently) contains only the WAR files.

  • Caesar Cipher Program In C++ [migrated]

    - by xaliap81
    I am trying to write a caesar cipher program in c++. This is my codes template: int chooseKEY (){ //choose key shift from 1-26 } void encrypt (char * w, char *e, int key) { //Encryption function, *w is the text in the beginning, the *e is the encrypted text //Encryption in being made only in letters noy in numbers and punctuations // *e = *w + key } void decrypt (char * e, char *w, int key) { // Decryption function, *e is the text in the beginning, the *w is the decrypted text //Dencryption in being made only in letters no numbers and punctuations // *w = *e - key } void Caesar (char * inputFile, char * outputFile, int key, int mode) { // Read the inputfile which contains some data. If mode ==1 then the data is being //encrypted else if mode == 0 the data is being decrypted and is being written in //the output file } void main() { // call the Caesar function } The program has four functions, chooseKey function have to return an int as a shift key from 1-26. Encrypt function has three parameters, *w is the text in the beginning, *e is the encrypted text and the key is from the choosekey function.For encryption : Only letters have to be encrypted not numbers or punctuation and the letters are counting cyclic. Decrypt function has three parameters *e is the encrypted text, *w is the beginning text and the key. Caesar function has four parameters, inputfile which is the file that contains the beginning text, output file which contains the encrypted text, the key and the mode (if mode==1) encryption, (mode ==0) decryption. This is my sample code: #include <iostream> #include <fstream> using namespace std; int chooseKey() { int key_number; cout << "Give a number from 1-26: "; cin >> key_number; while(key_number<1 || key_number>26) { cout << "Your number have to be from 1-26.Retry: "; cin >> key_number; } return key_number; } void encryption(char *w, char *e, int key){ char *ptemp = w; while(*ptemp){ if(isalpha(*ptemp)){ if(*ptemp>='a'&&*ptemp<='z') { *ptemp-='a'; *ptemp+=key; *ptemp%=26; *ptemp+='A'; } } ptemp++; } w=e; } void decryption (char *e, char *w, int key){ char *ptemp = e; while(*ptemp){ if(isalpha(*ptemp)) { if(*ptemp>='A'&&*ptemp<='Z') { *ptemp-='A'; *ptemp+=26-key; *ptemp%=26; *ptemp+='a'; } } ptemp++; } e=w; } void Caesar (char *inputFile, char *outputFile, int key, int mode) { ifstream input; ofstream output; char buf, buf1; input.open(inputFile); output.open(outputFile); buf=input.get(); while(!input.eof()) { if(mode == 1){ encryption(&buf, &buf1, key); }else{ decryption(&buf1, &buf, key); } output << buf; buf=input.get(); } input.close(); output.close(); } int main(){ int key, mode; key = chooseKey(); cout << "1 or 0: "; cin >> mode; Caesar("test.txt","coded.txt",key,mode); system("pause"); } I am trying to run the code and it is being crashed (Debug Assertion Failed). I think the problem is somewhere inside Caesar function.How to call the encrypt and decrypt functions. But i don't know what exactly is. Any ideas?

  • How can I make my binary file is served as binary, not text when user choose "Save Linked File As..." in Safari?

    - by Eonil
    I'm serving a binary file (.IPA) with Ubuntu/Apache 2.2. When I have chosen Save Linked File As... in Safari, it says it's text file. And it guides me to add .txt extension. However it does not add any extra extension when I download it just clicking link. I added line AddType application/octet-stream .ipa in apache configuration file. I don't know what's wrong with this. Is this a bug of Safari or my misconfiguration? (1) If it caused by bug, how can I avoid this? (2) Or if it caused by misconfiguration, what should I do?

  • krunner unreadable black text on black background. File a bug? Where?

    - by user52784
    I'm running Kubuntu 12.04 beta2 (up to date). Already tried to create a user from the scratch but the problem can still be replicated. I'll make it simple: with any of the available themes (air, air 4 netbooks, oxygen) whenever I disable desktop effects, KRunner instantly becomes black (with black fonts) rendering itself useless because of its unreadable text. Here is a screenshot I took: http://i42.tinypic.com/348sz7n.jpg The weird thing is that with effects enabled KRunner is "light gray" and perfectly functional. What can I do? Should I file a bug? If yes: where? On the KDE bug tracker or the Kubuntu one? Thanks in advance!

  • Zend Framework, Zend_Form_Element how to set custom name?

    - by ikso
    Hello, I have form, where some fields are looks like rows, so I can add/delete them using JS. For example: Field with ID=1 (existing row) <input id="id[1]" type="text" name="id[1]" value="1" /> <input id="name[1]" type="text" name="name[1]" value="100" /> Field with ID=2 (existing row) <input id="name[2]" type="text" name="name[2]" value="200" /> <input id="name[2]" type="text" name="name[2]" value="200" /> new row created by default (to allow add one more row to existing rows) <input id="id[n0]" type="text" name="id[n0]" value="" /> <input id="name[n0]" type="text" name="name[n0]" value="" /> new row created by JS <input id="id[n1]" type="text" name="id[n1]" value="" /> <input id="name[n1]" type="text" name="name[n1]" value="" /> So than we will proceed form, we will know what rows to update and what to add (if index starts with "n" - new, if index is number - existent element). I tried subforms... but do I have to create subform for each field? If I use following code: $subForm = new Zend_Form_SubForm(); $subForm->addElement('Text', 'n0'); $this->addSubForm($subForm, 'pid'); $subForm = new Zend_Form_SubForm(); $subForm->addElement('Text', 'n0'); $this->addSubForm($subForm, 'name'); What is the best way for this? 1) Use subforms? 2) Extend Zend/Form/Decorator/ViewHelper.php to use names like name[nX]? 3) Other solutions? Thanks.

    Hey, I would like to make an program that acts like a big filter for stocks. To do so, I need to have real-time (or delayed) quotes from the market. I started getting stock quotes by requesting pages from yahoo, accordingand parsing the html to the ticker, and parsing the html. I was wondering how to do this requesting and parsing html. Is there some way I can request only the stock quotes and its info? I know some applications do this, and I am very curious how they do it, because requesting web pages and parsing them is very time-consuming. Thanks, Dave

  • How to remove a plain text protecting single quote from all the selected cells in LibreOffice Calc?

    - by Ivan
    I've imported a CSV file having the first column to be date-time values in ISO 8601 format like 2012-01-01T00:00:00.000Z for the first moment of the year 2012. Then, willing to make LibreOffice to recognize the format (as I was looking forward to plot a diagram), I've selected the column, chosen Format Cells... and entered the custom time format as YYYY-MM-DDTHH:MM:SS.000Z And this seems to work if... I edit a cell to remove a hidden single-quote from its beginning (which serves to protect a cell content from being interpreted) as all the newly formatted cells now store values like '2012-01-01T00:00:00.000Z (note the single quote - it is only visible when you edit a particular cell). And I am to do so for all the cells in the column. How can I automate this? UPDATE: I've already found a solution for the particular case of mine: it helps to set a column format to "time" in the CSV import dialogue. But I am still curious how could this be done in case I wouldn't have the original .csv data file to import but only the .ods file with the data already imported without the format specified at the import time.

  • SQL Split function that handles string with delimeter appearing between text qualifiers?

    - by Ron
    There are several SQL split functions, from loop driven, to using xml commands, and even using a numbers table. I haven't found one that supports text qualifiers. Using the example string below, I would like to split on ",", but not when it appears between double or single quotes. Example data: [email protected], "Sally \"Heat\" Jones" <[email protected]>, "Mark Jones" <[email protected]>, "Stone, Ron" <[email protected]> Should return a table: [email protected] "Sally \"Heat\" Jones" <[email protected]> "Mark Jones" <[email protected]> "Stone, Ron" <[email protected]> I know this is a complex query/function, but any suggestions or any guidance would be mucho appreciated.

  • Where can I download a free, text-rich dataset?

    - by blee
    I want to do a bit of lightweight testing and bench-marking for full-text search, so the dataset should have the qualities: 10,000 - 100,000 records. good dispersion of English words. In CSV or Excel format--i.e. I don't want to access it via API. Something like books or movies with title and description fields would be perfect. I browsed the UCI Machine Learning Repo, but it was too number-oriented. Thanks!

  • Text editor with spell checker that ignores (X)HTML/CSS/javascript tags?

    - by Luis Soeiro
    Do you know of any text editor that can be used with a spell checker which is smart enough to ignore XHML/CSS and javascript tags? The requirements would be: It must run in Linux; It must be free and open source; It doesn't need to have WYSIWYG capabilities, but they would be welcome. It must have built in "tag skipping" capabilities or be configurable to skip (X)HTML tags, CSS and embedded Javascript; It doesn't need to have a HTML validator, but if it does it will be a plus; I've tried to use spell checker plugins for Kate, HTML validators for Firefox, Eclipse's HTML editor, but I couldn't find a solution that have a speel checker that ignores hml tags. Thanks for any help, Luís

  • Problems extracting information from RSS feed description field

    - by Graeme
    Hi, I've built an iPhone application using the parsing code from the TopSongs sample iPhone application. I've hit a problem though - the feed I'm trying to parse data from doesn't have a separate field for every piece of information (i.e. if it was for a feed about dogs, all the information such as dog type, dog age and dog price is contained in the feed. However, the TopSongs app relies on information having its own tags, so instead of using it uses and . So my question is this. How do I extract this information from the description field so that it can be parsed using the TopSongs parser? Can you somehow extract the dog age, price and type information using Yahoo Pipes and use that RSS feed for the feed? Or is there code that I can add to do it in application? Update: To view the code of my application parser (based on the TopSongs Core Data Apple provided application, see below. Here's a sample of one item from the the actual RSS feed I'm using (the description is longer, and has status,size, and a couple of other fields, but they're all formatted the same.: <item> <title>MOE, MARGRET STREET</title> <description> <b>District/Region:</b>&nbsp;REGION 09</br><b>Location:</b>&nbsp;MOE</br><b>Name:</b>&nbsp;MARGRET STREET</br></description> <pubDate>Thu,11 Mar 2010 05:43:03 GMT</pubDate> <guid>1266148</guid> </item> /* File: iTunesRSSImporter.m Abstract: Downloads, parses, and imports the iTunes top songs RSS feed into Core Data.

  • How to remove that extra text from URL titles in Firefox browser?

    - by amar
    I am using Firefox with Vimperator. On Mac I use Shiori to bookmark. I also use Pinboard's default add-on (on both Mac and Windows, but mainly on Windows as there's no Shiori). When I used to bookmark, I had this behaviour[A] (before changing Vimperator options): Example: URL: xyz.com TITLE: xyz website Pinboard add-on would fetch the title as xyz website which was fine (I reckon it directly fetches TITLE form the URL). But after installing and starting to use Shiori the title I was getting in its "title" field was xyz website - Vimperator exactly the same what I could see in tabs (seems it's getting what the browser is feeding it). So, I :set titlestring= in Vimperator to remove that extra Vimperator from title. Now, this is what I am getting [B]: When I try to bookmark using Pinboard add-on the title is undefined Using Shiori it results in xyz website - undefined. I tried to change it back to original[C] :set titlestring=Mozilla Firefox (assuming this was the original, before Vimperator) but the results are still the same as [B]. How to get read of that extra - undefined or that extra - Vimperator or - Mozilla Firefox for that matter, while bookmarking pages either with Pinboard add-on or Shiori? One workaround is, instead of no string just add a white-space while setting title in Firefox via Vimperator there but that results in - appended to titles.
