• Any risks in forwarding incoming requests to my computer? [closed]

  - by pimvdb

  I just installed EasyPHP, which is basically a combination of Apache, PHP and MySQL for dummies. I'd like to make my router forward incoming requests to my computer, so that everyone on the Internet could fetch data from my computer using the Apache server. However, I was wondering if there are many risks in this. For example: Could someone get full control of my computer this way? Is my computer more exposed to secutiry risks? Could I (practically) get DDOSed? The last question might be exaggerating, but I'm just curious. Thanks.

• Ubuntu Audio Pitch Shifting filter

  - by user777305

  I'm currently developing a video player software which intended to be an embeedded player. I'm using Java with VLCJ library for the video player. What i'm looking is a way, something to transform the audio output to make the output sound as oldman or a kid (pitch shifting, i guess is the name). VLC have this when enabling time stretch, but the video play speed is affected (slower to get oldman sound, but fast-forward-alike to get kid voice effect. Is there any solutions for this? I don't find this feature on VLC(J), so i think what i need is the audio output of the ubuntu itself (Ubuntu 12.04) to do this job. something like filtering audio output system wide. Any software or setting to do this? it also need to be controllable via command line to provide realtime effect changing. Thanks in advance.

  I was wondering if someone could help me how to manage temporarily inactive website in regards of SEO and search engine. the case is i managed a big ecommerce site, and sometime i need to put down page(s). could be days, could be weeks, could be months, and it depends on our vendor. if my visitors land on the page that been temporarily inactive then i can give them a message that the vendor they looking for is not available at this time and he can check back later OR check another vendor with similar products, but how do i send my message to search engine robots? if i use 301 status and forward URL page to another similar products, then the chance that the current URL being deindex is huge while i still want to use that URL for the future if my vendor want to re-join. any advise will highly appriciated

• How to make a scrolling background?

  - by Liamh101

  I'm making a Shooter game like "1943" and "Jamestown". I was wondering how I would make the background scroll up to simulate moving forward. I would also like it to scroll slightly to the left and right when the player reaches the sides of the screen. Finally, how would I make this efficient? I was thinking about using a animated GIF or to make a looping BitMap. Please could someone help me out. (I am Using Visual Basic 2010) Thanks!

• ASP.NET MVC 3 RC2 Razor- Syntax Intellisense in view.

  - by Jalpesh P. Vadgama

  Microsoft has recently launched Razor view engine with ASP.NET MVC RC2. It’s going to be promising one. There are lots of features bundled with this view engine. But in earlier version of ASP.NET 3 MVC. We were are not having Synatx intellisense provided for asp.net mvc views  in Visual Studio 2010. So either we have to depend third party tools like Resharper or we have to manage it without intellisesnse. But with ASP.NET MVC 3 RC2 Microsoft has moved one step forward and its providing syntax intellisense without installing any third party addons in Visual Studio. Here is example of it. Hope you liked it. Stay tuned for more.. Happy Programming..

• Can I randomly generate an endless road?

  - by y26jin

  So suppose we stand on a position(x0, y0) of a map. We can only move on the horizontal plane(no jump and stuff) but we can move forward, left, or right (in a discrete math way, i.e. integer movement). As soon as we move to the next position(x1, y1), everything around us is generated randomly by a program. We could be surrounded by one of mountain, lake, and road. We can only move on the road. The road is always 2D as the map itself. My question is, are we able to play this game endlessly? "End" means that we come across a dead end and the only way out is to go backward.

• How do I reset a lost Administrative(root) password?

  - by user9904

  I'm working on a Ubuntu 10.04 (Lucid Lynx) system using a Panasonic CF-50 Laptop. My Client has completely forgotten his Administrative Password. He doesn't even remember entering one; however it is there. I've tried the suggestions on the WebSite and I have been unsuccessful in deleting the password so that I can download applets required for running some files. Do you have a solution? I look forward to hearing your response. Thanks for your time and consideration.

• for vs. foreach vs. LINQ

  - by beccoblu

  When I write code in Visual Studio, ReSharper (God bless it!) often suggests me to change my old-school for loop in the more compact foreach form. And often, when I accept this change, ReSharper goes a step forward, and suggests me to change it again, in a shiny LINQ form. So, I wonder: are there some real advantages, in these improvements? In pretty simple code execution, I cannot see any speed boost (obviously), but I can see the code becoming less and less readable... So I wonder: is it worth it?

• Learning to program styles? [closed]

  - by MrNewbProgrammer

  I'm a beginner programmer and I am currently developing an application of my own, just for the fun of it and learning to program. I'm building it from scratch, because I think that in this way I will learn the most. I have stumbled upon MVC's and CMS, CodeIgniter really got my attention, and the basic use is very straight forward. But I do not understand the inner workings completely. So I have decided that it might be better to just develop from scratch and maybe return to codeIgniter later, was that good decision? Would it be better to use CodeIgniter and learn from that?

• How do I configure Mediawiki on EC2 if anonymous browsing is disabled?

  - by Feasoron

  So I have new MediaWiki instance install on a brand new Amazon EC2 instances. All is going swimmingly, until I have to log in via the web browser to configure it. Since I'm running on a hosted server, I can't hit http://localhost/mediawiki/config/index.php like the instructions say to. If I try to hit it via http://<My IP address>/mediawiki/config/index.php, my browser just tries to download the file because anonymous browsing isn't enabled. I seem to be before LocalSettings.php is created, so I don't know how to move forward from here.

  Originally posted on: http://geekswithblogs.net/rodelljr/archive/2014/06/03/androidsupporting-multiple-devices-part-2.aspxI would like to thank the KC Mobile App Developers group for allowing me to do my presentation; Supporting Multiple Devices Part 2. In this talk, I discussed a Master/Detail application that runs on Android 2.2 devices and forward. I used the Actionbar compat Android library to allow the older devices to have an actionbar. I also used a SQLite database for my data. And just to add one last thing, I also incorporated the use of custom fonts. If you are interesting in looking at this sample application, I have uploaded it to my GitHub account here. I also have a Power Point presentation which you can get here.I will be doing this talk again at a later date this year, so when I have a date and location, I will post a follow up blog.

• Prefer examples over Documentation. Is it a behavioral problem?

  - by user1324816

  Whenever I come across a new api or programming language or even simple Linux MAN pages, I always (ever since I remember) avoided then and instead lazily relied on examples for gaining understanding of new concepts. Subconsciously, I avoid documentation/api whenever it is not straight forward or cryptic or just plain boring. It's been years since I began programming and now I feel like I need to mend my ways as I now realize that I'm causing more damage by refraining from reading cryptic/difficult documentation as it is still a million times better than examples as the official documentation has more coverage than any example out there. So even after realizing that examples should be treated as "added" value instead of the "primary" source for learning. How do I break this bad habit as a programmer or am I over thinking? Any wisdom from fellow programmers is appreciated.

  I have a c# web browser and one of the pages it displays has a form. When the form is submitted it posts data to a new window in IE.

• How to get dropdown value using jsp:useBean and jsp:setProperty?

  - by littlevahn

  I have a rather simple form in JSP that looks like this: <form action="response.jsp" method="POST"> <label>First Name:</label><input type="text" name="firstName" /><br> <label>Last Name:</label><input type="text" name="lastName" /><br> <label>Email:</label><input type="text" name="email" /><br> <label>Re-enter Email:</label><input type="text" name="emailRe" /><br> <label>Address:</label><input type="text" name="address" /><br> <label>Address 2:</label><input type="text" name="address2" /><br> <label>City:</label><input type="text" name="city" /><br> <label>Country:</label> <select name="country"> <option value="0">--Country--</option> <option value="1">United States</option> <option value="2">Canada</option> <option value="3">Mexico</option> </select><br> <label>Phone:</label><input type="text" name="phone" /><br> <label>Alt Phone:</label><input type="text" name="phoneAlt" /><br> <input type="submit" value="submit" /> </form> But when I try and access the value of the select box in my Java class I get null. Ive tried reading it in as a String and an Array of strings neither though seems to be grabbing the right value. The response.jsp looks like this: <%@ page language="java" %> <%@ page import="java.util.*" %> <%@page contentType="text/html" pageEncoding="UTF-8"%> <%! %> <jsp:useBean id="formHandler" class="validation.RegHandler" scope="request"> <jsp:setProperty name="formHandler" property="*" /> </jsp:useBean> <% if (formHandler.validate()) { %> <jsp:forward page="success.jsp"/> <% } else { %> <jsp:forward page="retryReg.jsp"/> <% } %> I already have Java script validation in place but I wanted to make sure I covered validation and checking for non-JS users. The RegHandler just uses the name field to refer to the value in the form. Any Idea how I could access the select box's value?

• WPF FlowDocument: force calculation of height etc. "off screen"

  - by Lars

  My target: a DocumentPaginator which takes a FlowDocument with a table, which splits the table to fit the pagesize and repeat the header/footer (special tagged TableRowGroups) on every page. For splitting the table I have to know the heights of its rows. While building the FlowDocument-table by code, the height/width of the TableRows are 0 (of course). If I assign this document to a FlowDocumentScrollViewer (PageSize is set), the heights etc. are calculated. Is this possible without using an UI-bound object? Instantiating a FlowDocumentScrollViewer which is not bound to a window doesn't force the pagination/calculation of the heights. This is how I determine the height of a TableRow (which works perfectly for documents shown by a FlowDocumentScrollViewer): FlowDocument doc = BuildNewDocument(); // what is the scrollviewer doing with the FlowDocument? FlowDocumentScrollViewer dv = new FlowDocumentScrollViewer(); dv.Document = doc; dv.Arrange(new Rect(0, 0, 0, 0)); TableRowGroup dataRows = null; foreach (Block b in doc.Blocks) { if (b is Table) { Table t = b as Table; foreach (TableRowGroup g in t.RowGroups) { if ((g.Tag is String) && ((String)g.Tag == "dataRows")) { dataRows = g; break; } } } if (dataRows != null) break; } if (dataRows != null) { foreach (TableRow r in dataRows.Rows) { double maxCellHeight = 0.0; foreach (TableCell c in r.Cells) { Rect start = c.ElementStart.GetCharacterRect(LogicalDirection.Forward); Rect end = c.ElementEnd.GetNextInsertionPosition(LogicalDirection.Backward).GetCharacterRect(LogicalDirection.Forward); double cellHeight = end.Bottom - start.Top; if (cellHeight > maxCellHeight) maxCellHeight = cellHeight; } System.Diagnostics.Trace.WriteLine("row " + dataRows.Rows.IndexOf(r) + " = " + maxCellHeight); } } Edit: I added the FlowDocumentScrollViewer to my example. The call of "Arrange" forces the FlowDocument to calculate its heights etc. I would like to know, what the FlowDocumentScrollViewer is doing with the FlowDocument, so I can do it without the UIElement. Is it possible?
