• A bounce-rate attack to manipulate SEO ?

  - by Denis Volovik

  This is a question to experienced people that might help us shed some light on the issue. We noticed a very strange behavior on our site, in Google Analytics. Some dude from Finland, namely, from Kouvola city is hitting one of our pages - only one page on our site, 'bout a hundred times per day, all with an average bounce rate of 90%+... This is causing our overall bounce rate to go up by 1 to 3% per day... which is very disturbing.. since we're trying to do our best in order to keep it as low as possible. And obviously having it jumped from ~24% to 27%, just because of that crazy dude is not making us happy at all... We tried implementing a geo-targeted script in order to catch this particular visitor and deliver him a juicy message, and it seemed like it helped in the beginning, it has stopped for a day or two, but now he's back... The geo-targeted script was also logging all IP addresses for page requests originating from Finland in order to find out more details and (in order to block them on the server level, later).. but thing is, it was all mainly cable or DSL connections with various, but not constantly repeating IPs... we are all wondering what is he up to really ? I think that this page should be kept updated with ideas on how to combat this and perhaps someone could also shed light on what it might be ? What is the reason for doing this "bounce-rate attack", as I call it? There was a similar question asked on stackoverflow earlier, with no meaningful answer - here - How to stop bounce rate manipulation.

• A good tool for browser automation/client-side Web scripting

  - by hardmath

  I'm interested in adopting a tool/scripting language to automate some daily tasks connected with fighting forum spammers. A brief overview of these tasks: analyze new registrations and posts on a phpBB forum, and delete or deactivate spammers using a website/community that collects such spam reports. Typically such automation is integrated into the phpBB installation itself, which certainly has its advantages. My approach has the advantage of independent operation, etc. One way to think about this is in terms of browser automation. I've used iOpus iMacros for Firefox (the free version) in the past to respond to individual spammers, but current attacks are highly distributed. My "logic" for pigeonholing spammers vs. nonspammers seems beyond the easy reach of the free version of iMacros. From a more technical perspective one can think about dispensing with the browser altogether and programming GET/POST requests directed to my forum and other Web-based resources. I'm familiar with some scripting languages like Ruby and Lua, but I could be persuaded that a compiled application is better suited for these tasks. However in my experience the dynamic flexibility of interpreted environments is very useful in prototyping and debugging the application logic. So I'm leaning in the direction of scripting languages. Among browsers I favor Firefox and Chrome. I use both Windows and Linux platforms, and if the tool can adapt to an Android platform, it would make a neat demonstration of skills, yes? Thanks in advance for your suggestions!

• game multiplayer service development

  - by nomad

  I'm currently working on a multiplayer game. I've looked at a number of multiplayer services(player.io, playphone, gamespy, and others) but nothing really hits the mark. They are missing features, lack platform support or cost too much. What I'm looking for is a simple poor man's version of steam or xbox live. Not the game marketplace side of those two but the multiplayer services. User accounts, profiles, presence info, friends, game stats, invites, on/offline messaging. Basically I'm looking for a unified multiplayer platform for all my games across devices. Since I can't find what I'm planning to roll my own piece by piece. I plan to save on server resources by making most of the communication p2p. Things like game data and voice chat can be handled between peers and the server keeps track of user presence and only send updates when needed or requested. I know this runs the risk of cheating but that isn't a concern right now. I plan to run this on a Amazon ec2 micro server for development then move to a small to large instance when finished. I figure user accounts would be the simplest to start with. Users can create accounts online or using in game dialog, login/out, change profile info. The user can access this info online or in game. I will need user authentication and secure communication between server and client. I figure all info will be stored in a database but I dont know how it can be stored securely and accessed from webserver and game services. I would appreciate and links to tutorials, info or advice anyone could provide to get me started. Any programming language is fine but I plan to use c# on the server and c/c++ on devices. I would like to get started right away but I'm in no hurry to get it finished just yet. If you know of a service that already fits my requirements please let me know.

• How and where do you store your private work/sourcecode?

  - by Amir Rezaei

  I have worked as a developer for over 10 years now. During that time I have had my own small projects where I have developed tools, applications and games. I have not found any robust solution to store my work. It’s always fun to get back to your code and see how you did before and how you would do it now. It’s just work that is unfortunate to lose. There are SVN solution such as Google’s Project Hosting. However I’m not interested in sharing my code or making it open source. Currently I’m hosting my own SVN server. So here comes my question: How and where do you store your private work/sourcecode? Requirements: Sourcecode versioning Backup Prefers free Edit: Remote access Edit: I have used Dropbox + TrueCrypt + SVN. Unfortunately you are limited to 5gb.

• If Expression True in Immediate Window But Code In if Block Never Runs

  - by Julian

  I set a break point in my code in MonoDevelop to break whenever I click on a surface. I then enter the immediate window and test to see if the the if statement will return true in comparing two Vector3's. It does return true. However, when I step over, the code is never run as though the statement evaluated false. Does anyone know how this could be possible? I've attached a screenshot. Here is the picture of my debug window and immediate window. You can see where the immediate window evaluates to true. The second breakpoint is not hit. Here are the details of the two Vector3's I am comparing. Does anyone know why I am experiencing this? It really seems like an anomaly to me :/ Does it have something to do with threading?

• What is the best policy for allowing clients to change email?

  - by Steve Konves

  We are developing a web application with a fairly standard registration process which requires a client/user to verify their email address before they are allowed to use the site. The site also allows users to change their email address after verification (with a re-type email field, as well). What are the pros and cons of having the user re-verify their email. Is this even needed? EDIT: Summary of answers and comments below: "Over-verification annoys people, so don't use it unless critical Use a "re-type email" field to prevent typos Beware of overwriting known good data with potentially good data Send email to old for notification; to new for verification Don't assume that the user still has access to the old email Identify impact of incorrect email if account is compromised

• .NET - refactoring code

  - by w0051977

  I have inherited and now further develop a large application consisting of an ASP.NET application, VB6 and VB.NET application. The software was poorly written. I am trying to refactor the code as I go along. The changes I am making are not live (they are contained in a folder on my development machine). This is proving to be time consuming and I am doing this along side other work which is the prioritiy. My question is: is this a practical approach or is there a better methodology for refactoring code? I don't have any experience with version control software or source control software and I am wandering if this is what I am missing. I am a sole developer.

• Which tool to use for "home banking"?

  - by Huygens

  I would like to manage my bank accounts in a secure manner on Ubuntu. I saw several applications in the Software Centre, but I don't know which one to choose. I don't need fancy features like stock options. I just have regular accounts which I want to follow, I don't want complicated stuff. As bank data are quite sensitive, I would highly prefer an application that does encryption of the data. Though, if you have a really cool app but it does not have this feature, as long as it offers to store the data in one dedicated place, I could do with encrypting that place. So what tool do you use that could fit my needs?

• How do you dive into large code bases?

  - by miku

  What tools and techniques do you use for exploring and learning an unknown code base? I am thinking of tools like grep, ctags, unit-tests, functional test, class-diagram generators, call graphs, code metrics like sloccount and so on. I'd be interested in your experiences, the helpers you used or wrote yourself and the size of the codebase, with which you worked with. I realize, that this is also a process (happening over time) and that learning can mean "can give a ten minute intro" to "can refactor and shrink this to 30% of the size". Let's leave that open for now.

• Colleague unwilling to use unit tests "as it's more to code"

  - by m.edmondson

  A colleague is unwilling to use unit tests and instead opting for a quick test, pass it to the users, and if all is well it is published live. Needless to say some bugs do get through. I mentioned we should think about using unit tests - but she was all against it once it was realised more code would have to be written. This leaves me in the position of modifying something and not being sure the output is the same, especially as her code is spaghetti and I try to refactor it when I get a chance. So whats the best way forward for me?

• Joomla and Google Analytics advanced options in tracking code

  - by miako

  I want to insert google analytics tracking code in my joomla site. so i registered in the official site of google and saw there is an advanced tab with three more options than standard. Do i have to check "i want to track dynamic pages" and "i want to track php pages"? Do these options provide me better results or they are necessary for a dynamic site based on php like joomla? Does anyone know the process of installing? because i didn't manage to make it work by following this Also where do i place the tracking code? Because of some bugs some say it is better just after the tag <body> whereas other say just before the tag </body>. Thank you

• How do I avoid spam domains pointing to my site or IP

  - by Amol Ghotankar

  I came across an issue where I saw some xyz.com is pointing to mydomain.com. How do I avoid spam domains pointing to my domain? I read some posts about setting my virtual hosts and such, but nothing specific about how to avoid it in the first place. I searched on Google but most answers are for HTTP servers and there are no exact answers for Tomcat 7. I am not using Apache or IIS, but Tomcat directly.

• Can a programmer get too smart for their own good?

  - by P.Brian.Mackey

  The more I learn about programming, the more things I see that could be improved by a great deal. Often, a companies process management is total SWAG or they have Frames based websites written recently, .NET 1.1 based code, no separation of concerns, poor quality control...I could go on and on and on... Projects can succeed, but there tends to be so much waste I am amazed at how much time and money a company can throw away. I've seen it happen at several companies. So is it that ignorance truly is bliss? UPDATE Question "How is it that top developers (I don't mean like Jon Skeet level, I mean guys who are dedicated enough to hit a forum and try for self-improvement) even want to code anymore after they see the often insurmountable sociological and technical problems they are told to fix, but then scolded for doing so?

• managing information/functionality on shared common project classes

  - by ilansch

  In my company, we have a common solution the contains common projects (2 projects so far, one for .net 3.5 and one for .net 4.5). My main problem is that during time, a lot of code is added, for example hosting a process as windows service is a class called ServiceManagement, But no one but the developer knows it, and if someone wants to use this shared class, he does not know it exist. So i am looking for a way to document and manage all the classes with tags, a 3rd party util/web util, that i can search for tags and maybe find common classes that i can use (if we keep all our code well-documented). Does anyone familiar with sort of tools ?

• Hide admin menu if no admin option is available

  - by Jorge

  If you have a menu "Admin tasks" and different admin tasks (like 10) that you could separately assign to each user, but there are users who don't have any admin tasks, how would you deal with "Hiding admin menu" for those users? I was thinking of 3 ways: 1) Javascript, check if Admin menu is empty and then hide it. 2) Check for all permissions in Admin menu, with a counter, and show it if counter 0. And then also re-check the permissions for each item to show. 3) Save all permissions in associative array. Test all and assign ' true' to granted items. When building the menu, have a function that tests if there is at least one permission granted. I wouldn't need to re-check permissions against DB, just against the array for each item. Is there any better way?

• After Installation Whole Disk Encryption? 12.04

  - by Luke

  I know some fragments of this question have been asked in previous posts and I have reviewed them - however I have a more thorough question... I did not choose to do whole disk encryption when I used the alternative installer to install my 12.04 distro. I thought that truecypt worked with linux on system drive (whole disk) encryption - but sadly found out it did not. I have totally tweaked and pimped out my installation and I do not want to have to go back and "install" to just get whole disk encryption. Any alternatives that anyone knows of? I don't want just /home... I want the whole system installation protected and made secure so that when I boot I get a password to unencrypt.

• How to disable cryptswap?

  - by mit

  How can I disable cryptswap? I would like an unencrypted swap like before. This is on an ubuntu 9.10 system. It worked. First I removed the lines from /etc/fstab and /etc/crypttab. But it was not possible (and maybe not necessary?) to use the command sudo cryptsetup remove crytswap1 Before rebooting it was not possible (because cryptswap1 was still in use) and after rebooting cryptswap1 was already inactive. I removed cryptsetup from the system afterwards: sudo aptitude remove cryptsetup

• How to protect SHTML pages from crawlers/spiders/scrapers?

  - by Adam Lynch

  I have A LOT of SHTML pages I want to protect from crawlers, spiders & scrapers. I understand the limitations of SSIs. An implementation of the following can be suggested in conjunction with any technology/technologies you wish: The idea is that if you request too many pages too fast you're added to a blacklist for 24 hrs and shown a captcha instead of content, upon every page you request. If you enter the captcha correctly you've removed from the blacklist. There is a whitelist so GoogleBot, etc. will never get blocked. Which is the best/easiest way to implement this idea? Server = IIS Cleaning out the old tuples from a DB every 24 hrs is easily done so no need to explain that.

• Is SimplePHPBlog a secure blogging engine?

  - by authentictech

  Has anyone used the blog engine SimplePHPBlog? It is a simple blog engine that uses only text files (no database). My problem with it is that the content directory where the texts files are stored appears to require being world writeable/readable (i.e. permission 777) for it to work. This means anyone can access the text files with a browser! These text files include the blog/comment poster's IP and email address! This is not secure or good practice, right?

• Coordinating team code review sessions

  - by Wade Tandy

  My question has two parts: 1) In your team or organization, do you ever do in-person code reviews with all or part of a team, as opposed to online reviews using some sort of tool? 2) How do you structure these meetings? Do you choose to focus on one person's code in a given meeting? Do you look at everything? Take a random sample? Ask people on the team what they'd like to have looked at of theirs? I'd love to add this practice to my development team, so I'd like to hear how others are doing it.
