• America The Vulnerable

  - by Naresh Persaud

  At the Executive Edge this week, Joel Brenner shared his perspective on the state of cyber-security. Today our most critical military and corporate secrets are under attack. In his presentation, Joel shared his perspective on how organizations can can better prepare for the changing security climate. The amount of state sponsored espionage has highlighted weaknesses in our national security infrastructure. The Internet was primarily intended to provide a means of collaboration for non-commercial entities. Today it is the backbone of our digital commerce and digital experience and it was not designed to secure the activities and data we share today.  Check out "America The Vulnerable" and learn more.

• How to get useful feedback/bug reports from users

  - by Mikael Eliasson

  I'm sure most webmasters have recived a mail like this: Creating [insert item here] is not working! When you check it out there is no general problem with the function but rather the user has discovered an edge case. Almost every mail I get is like this and in the long run it gets a bit annoying to always have to ask the user for more information. Is there anything I can do to get my users provide more useful feedback? Right now I have a mailto: for the webmaster mail in the page footer. I was thinking of changing this so that they have to report through a form on the site. Anyone got any experience with this? Do you get better/more reports by having a feedback form instead of giving the users the email?

• CUDA instructions ask to stop GDM but it doesn't exist

  - by Gabs

  I am trying to install and run some CUDA exemples in Ubuntu 12.04. First of all, I downloaded all .run files from http://developer.nvidia.com/cuda-downloads, then followed the instructions at http://developer.nvidia.com/nvidia-gpu-computing-, until I got hung up on the first step: Exit the GUI if you are in a GUI environment by pressing Ctrl-Alt-Backspace. Some distributions require you to press this sequence twice in a row; others have disabled it altogether in favor of a command such as sudo /etc/init.d/gdm stop . Still others require changing the system runlevel using a command such as /sbin/init 3 to exit the GUI. When I type the command sudo /etc/init.d/gdmstop, it returns: gdm command not found Can anybody help me exit my GUI in order to continue? Thank you in advance.

• SVG images grow and create scrollbars when on the server

  - by zuko

  Okay so I embedded some SVG images into my page and opened it locally on Chrome and it looked fine. I upload the same file to the server and look at the page online and the SVG images have grown by maybe 5-10% and are surrounded by scroll bars like they are overflowing. I think it probably has to do with my lack of knowledge on how SVG and Embed work. What's really puzzling me though, is that it works fine locally. (I have cache disabled.) Help? Thanks. Edit: code HTML: <embed type="image/svg+xml" src="content/web-logo.svg"/> There's no CSS on the image. I'm not sure if I was just wrong before or if I changed something I'm not aware of, but it doesn't appear to be actually changing size anymore. It just decides to stuff it into a scrollbox. pic: https://www.dropbox.com/s/wt1aufi7nl1fpyi/svg-problem.png

• Value Not Updating? Check for Caching!

  - by Ken Cox [MVP]

  Here’s today’s dumb mistake: A value that was supposedly updated by a routine on one page, wasn’t changing on another ASP.NET screen. I carefully traced the progress of the update and everything looked right – all the way to the database. After puzzling over why the value wouldn’t show correctly on the ASP.NET grid, it finally dawned on me: <%@ OutputCache Duration="30" VaryByParam="none" %> Ouch! To improve efficiency, I had told the page to cache the output for 30 seconds...(read more)

• Creating a Template Like System in cPanel

  - by clifgray

  I am creating a medium sized website using cPanel and their File Manager system and the majority of my pages are going to be the same with a different title and content section and I wanted to see if there is a system for making one general template file and then having all the other pages inherit from that file so all I have to do is have a content and title section and the rest of the links, headers, and whatnot can be changed throughout the site by just changing one file. Is there anything like this? I have used Jinaj2 in python and a few other systems for other server scripting languages but I am not sure how to implement it with cPanel.

• unable to enter bios

  - by fraz

  I have an asus desktop ( amd phenom X6 processor) which was preinstalled with windows 7. I wanted to install ubuntu on it (dual boot) but am unable to do so because of the boot order. So I thought of changing boot order thru bios. But it turns out, if I press any key while the computer is starting, it just doesnt boots. I can see that the keyboard and mouse are booted up. (the lights are on) but the monitor is in standby mode.. I tried tab, f2,f10, delete key. But nothing is working.. Is there a software or other alternate on how can I change boot order ? Thanks

• In the context of semantic versioning, does a change in the default configuration warrant a new major version?

  - by michielvoo

  My module is enabled by default (i.e. when you add the module). There's also a configuration you can optionally use, which supports an enabled="true|false" setting. This way the module can be disabled after it's been added, without the need to remove the module. But I realized the module doesn't play nicely with another module that is also enabled by default. I am considering changing my module so it's not be enabled by default. This would break for anyone that has not explicitly enabled it with the enabled="true" configuration setting. Should I wait for v2.0 for this? semver.org mentions the public API and breaking changes, not configuration. Is it generally accepted that configuration is part of the public API?

• Sharing VBO with multiple objects and fixed size buffer data

  - by Mark Ingram

  I'm just messing around with OpenGL and getting some basic structures in place and my first attempt resulted in each SceneObject class (just contains vertex information right now) having it's own VBO inside it, however I've read that it might be better to share VBOs across multiple objects. Also, I read that you should avoid resizing a VBO (repeated calls to glBufferData with different size parameters), and instead choose a fixed size for a VBO, and just try a range from the buffer. I don't think changing the size of the buffer data would happen too often, but surely it would be better to only allocate the data you need? Choosing an arbitrary value seems risky. I'm looking for some advice on working with individual objects in a scene and their associated buffer data.

• Need to redirect Wordpress category archives

  - by Scott

  I recently changed my Wordpress category structure a bit, changing some of the names and placing some under different parent categories. I don't use category name in my post URLs, so that's not a problem. But my category archive pages are indexed and have page rank I don't want to lose. So I need to redirect: "/category/old_cat_name" to "/category/new_cat_name". Or in some cases to /new_cat_name/new_sub_cat. I gather that I can't do this though the WP Redirection plugin and that I have to modify my .htaccess. Can someone show me what lines to add there--or is there another better way to do this? Thanks.

• How do I change the volume control icon?

  - by Richard Oren Pincook

  I recently switched to gnome 3 (love it!), but the default icon theme was a little dreary and gray, so I switched that back to ubuntu-mono-dark. But now whenever I change my volume, I get this ugly pixelated icon show up. The forum says I don't have enough reputation to post an screenshot, but it's pixelated and ugly with these fuzzy straight blue lines that turn on as the volume goes up. I found identical images in the Humanity and Humanity-Dark icon themes (one example: /usr/share/icons/Humanity/status/24/audio-volume-high.png). I tinkered with the images by changing their names, temporarily deleting them, etc. But it had no effect on the ugly icon. What file is responsible for violating the beauty of my desktop?! Once I find it, I can replace it.

• Simulating Smartphones on PC with Unity

  - by Cengiz Frostclaw

  I want to make a game that depends on the phone orientation (changing shoot direction with tilt), however I need to test this on PC. So is there any tool I can use to simulate the orientation of the phone with mouse or keyboard of my PC? Something like joysticks on the screen. Thanks for any help! Edit : Thanks to @jhocking for his suggestion of Unity Remote. I, however still can accept a solution with using only PC, since I'm afraid of shortening my phone's battery life, for some reason.

• Is It bad for SEO to have internal redirected links? [closed]

  - by Jonas Lindqvist

  I have a large number of pages having similar but not identical content. Example: site.com/dream_dictionary_flying and site.com/dream_interpretation_flying. The problem is that although not being identical, they are sometimes on the edge of being duplicate content. The solution via redirect 301 in htaccess is simple and can be done in a minute, BUT, changing all existing links on the whole site from "/something" to "/something_else" would take ages, it would be thousands of manual changes taking x hundreds of hours. My question is this; is it bad for SEO to have internal links that are redirected, or rather HOW bad is it? For the human user it would not matter at all but from what I have experienced, the search engines don't like it. Is there any rule of thumb here? Please come back with your thoughts and experience on this. Thanks!

• Tracking AdWord ads with different text in Google Analytics

  - by at01

  I'm trying to see how the text in my Google AdWords ads affects my metrics in Analytics. I have auto-linking enabled, so I figured I would be able to automatically see this in Analytics. Unfortunately, if I try to add a second dimension of Traffic Sources-Ad Content, the metrics are only split by the ad's Headline. Most of my tests are changing only the ads' descriptions... So I guess I need to add a tracking parameter like ?campaign=special_text to my URLs? Or is there a way to see the ads split by ad descriptions? Should I add the full suite of utm_campaign/utm_medium/etc parameters? What's the proper way to track these ads which are mostly similar except the ad descriptions?

• window decoration command change

  - by Pedro

  I'm quite new to Ubuntu, and I don't know how to fix this: I have been experiencing the problem with window decorations that go away. I have been told that I could correct that with compiz fusion icon, just restarting the graphics whenever it happened. This solution only fixed the problem for like 30 seconds. Then I found out that the command inside the window decorator had changed, so I only had to reset it to default (/usr/bin/compiz-decorator). The only problem is that it keeps changing the command by itself once or twice a day. I can live with that, but I would like to find a more permanent solution, if there is one. I am running Ubuntu 11.10

• No boot record when installing 13.04 from USB on WinXP

  - by Phil Leslie

  I'm replacing WinXP with 13.04 on an older PC using wubi.exe on a USB stick. I had no problem changing the BIOS on another system that was a bit newer but when I change the settings on the older PC to boot from USB, I get a DOS message saying "Searching for boot record...Not found" & asked to try again. I don't have the ability to boot from a live CD so is there a reason why I can boot from a USB on a newer computer but can't from an older one? Both have options to choose to boot from USB, but the older one can find no boot record. The system was built on 12/13/01 by American Megatrends. Since I don't have enough "reputation points" to post the screen shot image, you can see it at http://img.photobucket.com/albums/v633/boonevillephil/1029131748-00.jpg.

• How to Delete/Disable gnome panels. No existing solutions working.

  - by Alan Peabody

  I would like to remove gnome panel completely. I spend most of my time in a (tmux) terminal or a browser. Synapse and a small hidden AWN panel fit the rest of my needs. I have tried all recommended solutions including this (found it a few places): How to delete Gnome Panel? However it always comes back at log in. I have tried changing the required components panel to avant-whatever as well as to empty. I have tried setting them both as default (right click set as default). Right now I just have the last panel set to transparent and auto hide, but it still tends to be annoying. What do I need to do to get rid of this damn thing?

• How do you navigate and refactor code written in a dynamic language?

  - by Philippe Beaudoin

  I love that writing Python, Ruby or Javascript requires so little boilerplate. I love simple functional constructs. I love the clean and simple syntax. However, there are three things I'm really bad at when developing a large software in a dynamic language: Navigating the code Identifying the interfaces of the objects I'm using Refactoring efficiently I have been trying simple editors (i.e. Vim) as well as IDE (Eclipse + PyDev) but in both cases I feel like I have to commit a lot more to memory and/or to constantly "grep" and read through the code to identify the interfaces. As for refactoring, for example changing method names, it becomes hugely dependent on the quality of my unit tests. And if I try to isolate my unit tests by "cutting them off" the rest of the application, then there is no guarantee that my stub's interface stays up to date with the object I'm stubbing. I'm sure there are workarounds for these problems. How do you work efficiently in Python, Ruby or Javascript?

• Getting Windows Azure SDK 1.1 To Talk To A Local DB

  - by Richard Jones

  Just found this, if you’re using Azure 1.1,  which you probably will be if yo'u’ve moved to Visual Studio 2010. To change the default database to something other than sqlexpress for Development Storage do this - Look at this - http://msdn.microsoft.com/en-us/library/dd203058.aspx At the bottom it states -   Using Development Storage with SQL Server Express 2008 By default the local Windows Group BUILTIN\Administrator is not included in the SQL Server sysadmin server role on new SQL Server Express 2008 installations.  Add yourself to the sysadmin role in order to use the Development Storage Services on SQL Server Express 2008.  See SQL Server 2008 Security Changes for more information. Changing the SQL Server instance used by Development Storage By default, the Development Storage will use the SQL Express instance.  This can be changed by calling “DSInit.exe /sqlinstance:<SQL Server instance>” from the Windows Azure SDK command prompt.

• Why were annotations introduced in Spring and Hibernate?

  - by Chandrashekhar

  I would like to know why were annotations introduced in Spring and Hibernate? For earlier versions of both the frameworks book authors were saying that if we keep configuration in xml files then it will be easier to maintain (due to decoupling) and just by changing the xml file we can re-configure the application. If we use annotations in our project and in future we want to re-configure application then again we have to compile and build the project. So why were these annotations introduced in these frameworks? From my point of view annotations make the apps dependent on certain framework. Isn't it true?

• Dynamic Quad/Oct Trees

  - by KKlouzal

  I've recently discovered the power of Quadtrees and Octrees and their role in culling/LOD applications, however I've been pondering on the implementations for a Dynamic Quad/Oct Tree. Such tree would not require a complete rebuild when some of the underlying data changes (Vertex Data). Would it be possible to create such a tree? What would that look like? Could someone point me in the correct direction to get started? The application here would, in my scenario, be used for a dynamically changing spherical landscape with over 10,000,000 verticies. The use of Quad/Oct Trees is obvious for Culling & LOD as well as the benefits from not having to completely recompute the tree when the underlying data changes.

• How can we reduce downtime at the end of an iteration?

  - by Anna Lear

  Where I work we practice scrum-driven agile with 3-week iterations. Yes, it'd be nice if the iterations were shorter, but changing that isn't an option at the moment. At the end of the iteration, I usually find that the last day goes very slowly. The actual work has already been completed and accepted. There are a couple meetings (the retrospective and the next iteration planning), but other than that not much is going on. What sort of techniques can we as a team use to maintain momentum through the last day? Should we address defects? Get an early start on the next iteration's work anyway? Something else?

• What features would you like to have in PHP? [closed]

  - by StasM

  Since it's the holiday season now and everybody's making wishes, I wonder - which language features you would wish PHP would have added? I am interested in some practical suggestions/wishes for the language. By practical I mean: Something that can be practically done (not: "I wish PHP would guess what my code means and fix bugs for me" or "I wish any code would execute under 5ms") Something that doesn't require changing PHP into another language (not: "I wish they'd drop $ signs and use space instead of braces" or "I wish PHP were compiled, statically typed and had # in it's name") Something that would not require breaking all the existing code (not: "Let's rename 500 functions and change parameter order for them") Something that does change the language or some interesting aspect of it (not: "I wish there was extension to support for XYZ protocol" or "I wish bug #12345 were finally fixed") Something that is more than a rant (not: "I wish PHP wouldn't suck so badly") Anybody has any good wishes? Mod edit: Stanislav Malyshev is a core PHP developer.

• Cannot Update through Manager or Terminal/ Software Center Does Not Work

  - by BROBA

  I installed Tor a few days ago via the terminal. I deleted some hashtags in the gedit polipo, and changed my proxy settings in chrome, but was unable to make it work and have since changed all of it back. I then downloaded the Tor browser bundle which works great, but ever since then have been unable to download updates or new software. The update manager says to "check internet connection" and the software center displays a mostly blank screen under apps like "rhythmbox" and just says "available from main source" when I click on "use this source" a refresh symbol appears on the upper right corner of the software center for a split second, and then nothing happens. The app does not download and isn't available in the dash. When I try via the terminal it says it's unable to connect to my ip address. I tried changing the server and unchecking all the repository options for software sources, all to no avail. WHAT DID I DO?????
