• Semantic algorithms

  - by Mythago

  I have a more theoretical than practical question. I'll start with an example - when I get an email and open it on my iPad, there is a feature, which recognizes the timestamp from the text and offers me to create an event in the calendar. Simply told, I want to know theoretically how it's done - I believe it's some kind of semantic parsing, and I would like if someone could point me to some resources, where I can read more about this.

• How to Use Heading Tags and Alt Attributes

  If you're working with HTML code for the first time, you may be wondering why Heading tags and alt attributes are used as a guide to data within your site's architecture. Search Engine Optimization consultants use HTML header tags to summarize the topic of the page it introduces. Google and other search engines analyze text inside header tags in their algorithm to assign web page rankings. To rank for your target keywords and phrases, incorporate them into your HTML page headers.

• Running CLOC (count lines of code) on Windows...or alternative

  - by Chelonian

  I'm trying to use CLOC on Windows (XP) to count lines of code, and I can't get it to work. I downloaded the latest Win installer for CLOC 1.5.6, ran it (which caused a "DOS" window to open, scroll with text rapidly, then close before I could read anything) and then wrote cloc at the cmd prompt...and Windows doesn't recognize it as a command. Or if there is another easy-to-use lines of code counter that one could recommend (that runs on Windows), I'd be happy to try that.

• Does Geany or Gedit provide a browser protocol in the way Textmate does with txmt://?

  - by Rich

  Textmate on the Mac can be bound to the txmt protocol, meaning that development frameworks (such as the Play Framework) can be configured to use this to display error messages. If a stacktrace appears, each line of the stacktrace is a URL of the format (I'm guessing): txmt:///home/myuser/projects/myproject/ProblemFile.java:123 (where 123 is the line number). Clicking this opens the file in Textmate. Is this possible with Gedit, Geany or another programmer's text editor?

• Scanning the Error Log with PowerShell

  - by AllenMWhite

  One of the most important things you can do as a DBA is to keep tabs on the errors reported in the error log, but there's a lot of information there and sometimes it's hard to find the 'good stuff'. You can open the errorlog file directly in a text editor and search for errors but that gets tedious, and string searches generally return just the lines with the error message numbers, and in the error log the real information you want is in the line after that. PowerShell 2.0 introduced a new cmdlet...(read more)

• Search For a Query in RDL Files with PowerShell

  - by AllenMWhite

  In tracking down poorly performing queries for clients I often encounter the query text in a trace file I've captured, but don't know the source of the query. I've found that many of the poorest performing queries are those written into the reports the business users need to make their decisions. If I can't figure out where they came from, usually years after the queries were written, I can't fix them. First thing I did was find a great utility called RSScripter , which opens up a Windows dialog...(read more)

• Page views in Google Analytics are off compared to a similar metric

  - by tiki16

  We have a page where a user can sign a pledge to recycle by clicking a pledge button. A script writes it to a text file which updates the number on the page. In the past 2 days there have been 185 pledges signed but only 63 page views in GA. I trust that they are unique pledges and not just people adding multiple fake names and entering it. Is there anyway to get a better report from Google Analytics?

• Lazy Processing of Streams

  - by Giorgio

  I have the following problem scenario: I have a text file and I have to read it and split it into lines. Some lines might need to be dropped (according to criteria that are not fixed). The lines that are not dropped must be parsed into some predefined records. Records that are not valid must be dropped. Duplicate records may exist and, in such a case, they are consecutive. If duplicate / multiple records exist, only one item should be kept. The remaining records should be grouped according to the value contained in one field; all records belonging to the same group appear one after another (e.g. AAAABBBBCCDEEEFF and so on). The records of each group should be numbered (1, 2, 3, 4, ...). For each group the numbering starts from 1. The records must then be saved somewhere / consumed in the same order as they were produced. I have to implement this in Java or C++. My first idea was to define functions / methods like: One method to get all the lines from the file. One method to filter out the unwanted lines. One method to parse the filtered lines into valid records. One method to remove duplicate records. One method to group records and number them. The problem is that the data I am going to read can be too big and might not fit into main memory: so I cannot just construct all these lists and apply my functions one after the other. On the other hand, I think I do not need to fit all the data in main memory at once because once a record has been consumed all its underlying data (basically the lines of text between the previous record and the current record, and the record itself) can be disposed of. With the little knowledge I have of Haskell I have immediately thought about some kind of lazy evaluation, in which instead of applying functions to lists that have been completely computed, I have different streams of data that are built on top of each other and, at each moment, only the needed portion of each stream is materialized in main memory. But I have to implement this in Java or C++. So my question is which design pattern or other technique can allow me to implement this lazy processing of streams in one of these languages.

• Search Engine Optimization - A Part of Web Promotion

  Search Engine Optimization (SEO) is considered as a technical part of Web promotion. This is true because it does lend a hand in the advertising of websites and simultaneously it requires some technical understanding - as a minimum familiarity with fundamental HTML. It is sometimes also called SEO copyrighting since most of the practice that are used to egg on sites in search engines pact with text.

• A Simple Collapsible Menu with jQuery

  - by Vincent Maverick Durano

  In this post I'll demonstrate how to make a simple collapsible menu using jQuery. To get started let's go ahead and fire up Visual Studio and create a new WebForm.  Now let's build our menu by adding some div, p and anchor tags. Since I'm using a masterpage then the ASPX mark-up should look something like this:   1: <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> 2: <div id="Menu"> 3: <p>CARS</p> 4: <div class="section"> 5: <a href="#">Car 1</a> 6: <a href="#">Car 2</a> 7: <a href="#">Car 3</a> 8: <a href="#">Car 4</a> 9: </div> 10: <p>BIKES</p> 11: <div class="section"> 12: <a href="#">Bike 1</a> 13: <a href="#">Bike 2</a> 14: <a href="#">Bike 3</a> 15: <a href="#">Bike 4</a> 16: <a href="#">Bike 5</a> 17: <a href="#">Bike 6</a> 18: <a href="#">Bike 7</a> 19: <a href="#">Bike 8</a> 20: </div> 21: <p>COMPUTERS</p> 22: <div class="section"> 23: <a href="#">Computer 1</a> 24: <a href="#">Computer 2</a> 25: <a href="#">Computer 3</a> 26: <a href="#">Computer 4</a> 27: </div> 28: <p>OTHERS</p> 29: <div class="section"> 30: <a href="#">Other 1</a> 31: <a href="#">Other 2</a> 32: <a href="#">Other 3</a> 33: <a href="#">Other 4</a> 34: </div> 35: </div> 36: </asp:Content>   As you can see there's nothing fancy about the mark up above.. Now lets go ahead create a simple CSS to set the look and feel our our Menu. Just for for the simplicity of this demo, add the following CSS below under the <head> section of the page or if you are using master page then add it a the content head. Here's the CSS below:   1: <asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server"> 2: <style type="text/css"> 3: #Menu{ 4: width:300px; 5: } 6: #Menu > p{ 7: background-color:#104D9E; 8: color:#F5F7FA; 9: margin:0; 10: padding:0; 11: border-bottom-style: solid; 12: border-bottom-width: medium; 13: border-bottom-color:#000000; 14: cursor:pointer; 15: } 16: #Menu .section{ 17: padding-left:5px; 18: background-color:#C0D9FA; 19: } 20: a{ 21: display:block; 22: color:#0A0A07; 23: } 24: </style> 25: </asp:Content>   Now let's add the collapsible effects on our menu using jQuery. To start using jQuery then register the following script at the very top of the <head> section of the page or if you are using master page then add it the very top of  the content head section.   <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js" ></script>   As you can see I'm using Google AJAX API CDN to host the jQuery file. You can also download the jQuery here and host it in your server if you'd like. Okay here's the the jQuery script below for adding the collapsible effects:   1: <script type="text/javascript"> 2: $(function () { 3: $("a").mouseover(function () { $(this).addClass("highlightRow"); }) 4: .mouseout(function () { $(this).removeClass("highlightRow"); }); 5:   6: $(".section").hide(); 7: $("#Menu > p").click(function () { 8: $(this).next().slideToggle("Slow"); 9: }); 10: }); 11: </script>   Okay to give you a little bit of explaination, at line 3.. what it does is it looks for all the "<a>" anchor elements on the page and attach the mouseover and mouseout event. On mouseover, the highlightRow css class is added to <a> element and on mouse out we remove the css class to revert the style to its default look. at line 6 we will hide all the elements that has a class name set as "section" and if you look at the mark up above it is refering to the <div> elements right after each <p> element. At line 7.. what it does is it looks for a <p> element that is a direct child of the element that has an ID of "Menu" and then attach the click event to toggle the visibilty of the section. Here's how it looks in the page: On Initial Load: After Clicking the Section Header:   That's it! I hope someone find this post usefu!   Technorati Tags: ASP.NET,JQuery,Master Page,JavaScript

• Is there a tool for detecting sites using the same template?

  - by KTB

  I often buy webtemplates online, and when I do so I often look at the demos to get some inspiration on how to use the components. But I would love to look at other sites which have already implemented a full website using this template. So I am looking for a tool which searches sites having a similar HTML as the demos (and therefore are probably implementing the template). I am referring to templates which do not have a static text like "Created with Template FooBar by BarFoo" in the footer.

• Best language on Linux to replace manual tasks that use SSH/Telnet? [on hold]

  - by Calab

  I've been tasked to create and maintain a web browser based interface to replace several of the manual tasks that we perform now. I currently have a "shakey" but working program written in Perl (2779 lines) that uses basic Expect coding, but it has some limitations that require a great deal of coding to get around. Because of this I am going to do a complete rewrite and want to do it "right" this time. My question is this... What would be the best language to use to create a web based interface to perform SSH/Telnet tasks that we would normally do manually? Keep in mind the following requirements: Runs on a CentOS Linux system v5.10 Http will be served by Apache2 This is an INTRANET site and only accessible within our organization. User load will be light. No more that 5 users accessing it at one time. perl 5.8.8, php 5.3.3, python 2.7.2 are available... Not sure what other languages to check for, or what modules might be installed in each language. The web interface will need to provide progress indicators and text output produced by the remote connection, in real time as it is generated. If we are running our process on multiple hosts, they should be in individual threads so that they can run side by side, not sequentially. I want the ability to "trap" on specific text generated by the remote host and display an alert to the user - such as when the remote host generates an error message. I would like to avoid as much client side scripting (javascript/vbscript) as I can. Most users will be on Windows PC's using Chrome or IE as a browser. Users will be downloading the resulting output so they can process it as they see fit. I currently have no experience with "Ajax" or the like. Most of my coding experience is old 6809 assembly, Visual Basic 6, and whatever I can cut/paste from online examples in various languages (hence my "shaky" Perl program) My coding environment is Eclipse for remote code editing, but I prefer stuff like UltraEdit if I can get a decent syntax file for the language I'm using. I do have su access on the server, but I'm not the only one using this server so I can't just upgrade/install blindly as I might impact other software currently running on the machine. One reason that I'm asking here, instead of searching (which I did) is that most replies were, "use language 'xyz', but you need to use an external SSH connection" - like I'm using Expect in my Perl script. Most also did not agree on what language that 'xyz' should be. ...so, after this long posting, can someone offer some advice?

• A better way to organize your Silverlight Code Snippets.

  - by mbcrump

  I hate re-writing code. I also hate it when I find a great code snippet on the web and forget to bookmark it or it gets lost in my endless sea of bookmarks. So what do you do to get around this? This is the question that I was asking myself at the end of 2010. How can I get my Silverlight code organized? My requirements for a snippet manager were: Needs to be FREE. An easy way to view XAML/C# code behind together in one “view”. I wanted the ability to store the code snippets in cloud in case my HDD dies. Searchable Keywords to quickly find code snippets. I started looking for a snippet manager that would allow me to do just that and finally found Snippet Manager. Before going any further, I think that one of the most important things to note here is that this software supports 37 languages. It’s not just for Silverlight developers nor C# only guys. The software supports Java, SQL and even COBOL.   Below is a screenshot of the Snippet Manager that shows my Silverlight code snippet. You will notice that I have highlighted two sections. The top part is my XAML and the bottom is my C# code behind. I’ve included a sample below of my code snippets so that you can get an idea of how I organized it. Another thing that’s great about this software is that it supports plain text. I added some connection strings in the TEXT section below.  Once you have finished adding your code snippets, you can store them in the cloud. I created a FTP directory called “snippets” on my FTP Server and hit the upload button once I am finished adding my new codes snippets. This will allow me to use the code snippets on another computer with this application on my USB Key. See screenshots below: Enter your FTP credentials below: Hit the Uploads button on the Toolbar: Login in to your FTP Server and verify the following files are now on the FTP Server: Another great feature of the Snippet Manager is that you can also integrate this into VS2010 by clicking Tools –> External Tools: And setting up your External Screen to point to the Executable: You can now launch it by going to Tools –> Snippet Manager. If you want you could also a shortcut to launch the program with HotKeys. As you can see, this is a nice little program that includes everything needed to organize your code snippets very clean. I didn’t go over every feature but this is something that you might want to download and give it a shot.  Subscribe to my feed CodeProject

• Gnome-Shell 3.4 Themes not working in 12.04?

  - by CGriffitt

  Even themes advertised as Gnome-shell 3.4 compatible have graphical issues on Gnome-Shell 3.4. The main thing is that the text is black and nearly invisible, and the icons in the applications screen are crowded and in some cases overlapping. The themes did not do this before upgrade, and the default doesn't do it now. I am using user theme extension, and the themes I have tried are the Ambiance-Color set and London Smoke (both of which are advertised as 3.4 compatible).

• Is there a more efficient way to filter large arrays than preg_match()?

  - by hozza

  I have a log that our web application builds. Each month it contains around 16,000 entries of a string with about the average sentence worth of text. To filter/search through these in our admin panel the script uses preg_match() but this seems to be taking ages and timing out on the 30sec limit. I have isolated that it is indeed the preg_match() that causes the time out. Is there a more efficient way to search through values in a large array for a users input?
