• How to create email request forms and auto-responder?

  - by mfc

  I'm building a site in css and I'm pretty new to any code or script other than html and css. I'm trying to create a landing page that requires an email from visitors and set up an auto responder to send to that newly submitted email. This would also be a signup for email newsletters. I have some idea how to create the form and have looked into a bit. I don't know how to make it a requirement to get past the landing page and into the actual website or set up the auto-responder. Any help would be much appreciated. Or if someone knows of a source that explains how to do this thing in particular it would be wonderful. I tried lynda.com but everything is so general and I can't seem to find info on exactly how to do this but I know its quite common. Thanks!

• Does NASA license the software that it develops?

  - by Abe

  NASA provides a visualization software called Panoply. There is a Credits and Acknowledgments page that acknowledges and lists the licenses of software dependencies, but provides no information about its own license. I have looked at other software produced by NASA, including the source code for GISS and can not find any information about a licence. The closest information that I can find is in the FAQ for the global climate model EdGCM Global that says the code is in the "public domain" is it standard practice at NASA to release code into the public domain? are there exceptions? Can I assume that Panoply is public domain and can be used without restriction other than than those imposed by licenses of software dependencies? Is the absence of specific permission to reuse the code a concern (this issue was raised in the answer to a separate question) How common is this practice across government agencies?

• Google analytics/adwords account and leaking of private data

  - by Satellite

  I am frequently asked to log into clients google analytics and adwords accounts. If I forget to log out before visiting other google properties (google search, youtube etc), this leaves tracks of my views/searches etc, exposing my activities to the client. Summary: Client gives me access to their Google Analytics / AdWords account I log into clients Analytics account and do some stuff Then in another tab I perform some related google searches to solve some related issues Issues solved, I then close the Analytics tab I then visit google.com, perform some unrelated searches I then visit YouTube, view some unrelated videos All Web and YouTube searches are recorded in clients google account, thus leaking potentially sensitive data Even assuming that I remember to log out correctly at step 4 (as I do 95% of the time), anything I do at step 3 is exposed to the client. I would be surprised if this is not a very common issue. I'm looking for a technical solution to ensure that this can never happen. Any ideas?

• Why does Zend discourage "floating functions"?

  - by kojiro

  Zend's Coding Standard Naming Convention says Functions in the global scope (a.k.a "floating functions") are permitted but discouraged in most cases. Consider wrapping these functions in a static class. The common wisdom in Python says practically the opposite: Finally, use staticmethod sparingly! There are very few situations where static-methods are necessary in Python, and I've seen them used many times where a separate "top-level" function would have been clearer. (Not only does the above StackOverflow answer warn against overuse of static methods, but more than one Python linter will warn the same.) Is this something that can be generalized across programming languages, and if so, why does Python differ so from PHP? If it's not something that can be generalized, what is the basis for one approach or the other, and is there a way to immediately recognize in a language whether you should prefer bare functions or static methods?

• Ubuntu 11.10 Unity - all Windows decorations disappear after I maximize any window

  - by korda

  When I maximize some of the windows all decorations disappear (by all, I mean on all windows)... Is that common issue on Unity or I'm just unlucky to have some prone to that bug configuration? Anyone have idea how to fix this? EDIT: It won't fix after unmaximize. It seems like maximazing window simply crashes window decorator. Decoration isn't displayed for all existing windows and any new ones. Only way I found to fix this is to run compiz --replace (but this ruins current windows placement - all windows end up on same desktop). It happens almost every time I maximize window.

• Designing exceptions for conversion failures

  - by Mr.C64

  Suppose there are some methods to convert from "X" to "Y" and vice versa; the conversion may fail in some cases, and exceptions are used to signal conversion errors in those cases. Which would be the best option for defining exception classes in this context? A single XYConversionException class, with an attribute (e.g. an enum) specifying the direction of the conversion (e.g. ConversionFromXToY, ConversionFromYToX). A XYConversionException class, with two derived classes ConversionFromXToYException and ConversionFromYToXException. ConversionFromXToYException and ConversionFromYToXException classes without a common base class.

• Multiple Java EE Agents on Single Managed Server

  - by tina.wang

  A default JEE agent is created when you create domain, which is named as OracleDIAgent. 1. In Studio, duplicate the agent, change its name to genAgent, change the web application context to genagent. 2: Go to datasource of genAgent, drop all datasources.3: Generate server template. put the jar file under odi\common\templates\wls 4: Deploy this template by update the existing domain. Bring up the config.cmd, choose update existing domain. 5: Update the domain using the template that just generated. Go through the Configuration wizard. (I did not modify anything or configure anything here). 6: The wizard will give information says the deployment was successful. 7: Bring up the admin server and ODI_server1.

• How to improve quality of software

  - by hariharan

  Last week in our organization, we triggered a topic related to different ways of improving the quality of software (both technical as well as functional related topics). Since i am a technical person, i suggested following ideas, Use case based detailed design document – Both technical as well as functional specification should be well organized according to use case requirement. Design patterns – Will help developers to adopt common approach irrespective of technologies. Analyze and implement new technologies – Helps to improve the performance as well as the security of the application. As I am not a well experienced technical candidate , i am unable to provide other solutions. If any suggestions or topics related to this (including testing, functional requirement), please post your valuable comments.

• How Is My Computer Able to Restart Itself?

  It’s such a common place activity that most of us have likely never stopped to even think about it: the automatic restart. Whether user or application-initiated, what exactly happens when your computer cycles its own power?

• What is the general definition of something that can be included or excluded?

  - by gutch

  When an application presents a user with a list of items, it's pretty common that it permits the user to filter the items. Often a 'filter' feature is implemented as a set of include or exclude rules. For example: include all emails from [email protected], and exclude those emails without attachments I've seen this include/exclude pattern often; for example Maven and Google Analytics filter things this way. But now that I'm implementing something like this myself, I don't know what to call something that could be either included or excluded. In specific terms: If I have a database table of filter rules, each of which either includes or excludes matching items, what is an appropriate name of the field that stores include or exclude? When displaying a list of filters to a user, what is a good way to label the include or exclude value? (as a bonus, can anyone recommend a good implementation of this kind of filtering for inspiration?)

• How do I balance program CPU reverse compatibility whist still being able to use cutting edge features?

  - by TheLQ

  As I learn more about C and C++ I'm starting to wonder: How can a compiler use newer features of processors without limiting it just to people with, for example, Intel Core i7's? Think about it: new processors come out every year with lots of new technologies. However you can't just only target them since a significant portion of the market will not upgrade to the latest and greatest processors for a long time. I'm more or less wondering how this is handled in general by C and C++ devs and compilers. Do compilers make code similar to if SSE is supported, do this using it, else do that using the slower way or do developers have to implement their algorithm twice, or what? More or less how do you release software that takes advantage of newer processor technologies while still keeping a low common denominator?

• Why is better to use external JavaScript or libraries ; and is it prefered to use jquery meaning more security?

  - by shareef

  I read this article Unobtrusive JavaScript with jQuery and I noticed these points in the slide page 11 some companies strip JavaScript at the firewall some run the NoScript Firefox extension to protect themselves from common XSS and CSRF attacks many mobile devices ignore JavaScript entirely screen readers do execute JavaScript but accessibility issues mean you may not want them to I did not understand the fourth point. What does it mean? I need your comment and responses on these points. Is not using JavaScript and switching to libraries like jQuery worth it? UPDATE 1 : whats the meaning of Unobtrusive JavaScript with jQuery ? and yes it does not say we should use libraries but we should have them on external files for that reason i asked my question.

• Teaching: How can you motivate students to comment?

  - by keflavich

  I remember when I was taught, "comments are the most important part of code." Or rather, when I was told that comments are the most important part of the code. I don't think I was convinced, and I still see common cases where programmers are not convinced of the necessity of good & thorough comments. I am certainly convinced myself at this point - trying to read, in particular, complex formulae that call functions that call other functions that I don't understand - but I don't know how to convey this to students.

• When Your ASP.NET MVC Custom Error Doesn't Render...

  You've put [HandleError] on your controller and you've set <customErrors mode="On"> in the web.config file. So why do you still see the yellow screen of death? I've heard various wrong explanations for this phenomena, including "it only works under IIS" and "it only works in release mode". But the custom error view does work in debug mode and it does work with the Visual Studio WebDev web server. I think the most common reason for the error view not to display is because the error view throws...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Declarative Transactions in Node.js

  - by James Kingsbery

  Back in the day, it was common to manage database transactions in Java by writing code that did it. Something like this: Transaction tx = session.startTransaction(); ... try { tx.commit(); } catch (SomeException e){ tx.rollback(); } at the beginning and end of every method. This had some obvious problems - it's redundant, hides the intent of what's happening, etc. So, along came annotation-driven transactions: @Transaction public SomeResultObj getResult(...){ ... } Is there any support for declarative transaction management in node.js?

• Beginner help with compiling a driver into the kernel so my ethernet works

  - by MattC

  I have a Acer Aspire Revo nettop and it seems like it's a common error that Ubuntu doesn't have a driver for the ethernet. Someone recommend following the steps on this page. http://manpages.ubuntu.com/manpages/jaunty/man4/nfe.4freebsd.html The only problem is that I have no clue what to do really. I'm almost like an absolute beginner with linux and was hoping to play with it by doing some apache+php+mysql stuff, however I cannot at the moment. Where is the kernel configuration file? and where is the loader.conf file?

• php.ini modifications has no effect on joomla

  - by user488736

  I have a netbook with a recently installed ubuntu server 12.04 64-bit. I have (only) installed Joomla on it (version 2.5) and now I am trying to tweak the php.ini settings so I can install jomsocial onto joomla. I have changed these settings: upload_max_filesize = 2M post_max_size = 8M to this: upload_max_filesize = 20M post_max_size = 20M in all php.ini-files in my system. Thats six files, found using 'locate': /etc/php5/apache2/php.ini /etc/php5/cli/php.ini /usr/share/doc/php5-common/examples/php.ini-development /usr/share/php5/php.ini-production /usr/share/php5/php.ini-production-dist /usr/share/php5/php.ini-production.cli I have double-checked that these files actually contain the new settings. Still, joomla does not recognize the new settings, stating that upload_max_filesize is still only 2M and post_max_size is still only 8M The same is true after a complete restart of the server. What am I doing wrong here?

• Adding a list of "recent articles" affects SEO

  - by Groo

  We have a site which has a sidebar with sections (or "widgets" if you like) showing stuff like "Recent Articles", "Other Articles by this User", "Similar Articles" etc. The issue is, Google seems to take these links very seriously. In fact, if I have only a single article which is closely related to a certain phrase (and several other pages link to it in their sidebars), when I do a Google search, it lists all those other pages highlighting that one link to the page that should actually be the most relevant one. And these pages don't even mention the phrase anywhere else. It there a common approach with adding these sidebar links? For example, I might add them through ajax after the page is loaded, but then crawlers will have harder time finding them?

• Does distributing non-GPLd assets with a GPL application violate the license?

  - by Richard Szalay

  This is somewhat related to my other question, but is actually different. I would like to license a Windows Phone application under the GPL. All other Windows Phone Marketplace issues aside (I'll ask those on the forums), I'd like to include icons that ship with the SDK in my application. While this is common practice (documentation points to the icons' location), I'm not sure if I'd be forcing GPL on the icons (a move expressly forbidden by the Application Provider Agreement). How is this usually handled in GPL or am I simply out of luck?

• Strategies for porting application from Win32 API to GTK+

  - by Vitor Braga

  I have a legacy application written in C, using the raw Win32 API. The general level of abstraction is low and raw dependency on <windows.h> is common. I would like to port this application to GTK+. There are any kind of guidelines or best practices on how to do this? I've previously ported a MFC application to Qt, but the application was very abstracted - it draw it's own set of widgets, for example - and initial porting was very straightforward. I've been thinking at first using Wine to build a native Linux executable and then trying to slowly refactor it into a GTK+ app. Does some one have best practices or previous experiences to share about this?

• Ubuntu 13.04 ERROR: /etc/apt/sources.list not found

  - by Richard Riley

  So, I tried uninstalling the LAMP stack I had following the Ubuntu documentation for it. I also manually removed dbconfig-common. Now, I'm unable to run apt-get update. When I do, I get the error message: E: The method driver /usr/lib/apt/methods/htp could not be found. After some digging, I've discovered that I no longer even have an /etc/apt/sources.list file. Also, I've received an error, when trying to run: sudo tasksel install lamp-server That aptitude can not be found. Does anyone have an idea of what I can do? I'm not able to find any documentation online that works - all the documentation out there is dated and no longer (or will not) work with 13.04. I followed this link previously prior to posting my question and it did not work for me: How do I fix a "E: The method driver /usr/lib/apt/methods/http could not be found." error?

• How do I get "ruby" to do what "ruby1.9.1" does?

  - by Daniel

  I want to start off by saying... I really don't need to be using 1.9.2. I understand that you don't ever, ever use Python 3.2, so if the common advice is that I should use 1.8, I'll do that. But don't tell me to do that because it's easier. Whatever version I should be using, though, the question is still relevant: What's a good way to make one command do another command? (I suppose I could write a c program to launch ruby1.9.1, call the executable ruby, and put it in my bin, but this seems like less than a good idea)

• What is Perl's relation to hackers? [closed]

  - by K.Steff

  I know Perl is a language revered by many hackers (as in hacker vs cracker) and respected by many good programmers for its expressiveness. I also realize it is useful to know and it's very handy at generalizing common Unix tasks (Unix here includes Linux and Cygwin). I also know that being a good hacker probably means you're a good programmer in general (references on this one are sparse around the web, but about everything Paul Graham has ever written seems approving of this statement to me). So my question is whether there is a reason that attracts hackers to Perl in particular? Will learing Perl improve my general programming, problem-solving and hacking skills if done properly? Does it present unique tools that are more useful to a hacker?
