  • How can I find which "command" corresponds to opening a gnome-panel menu, for use in a keyboard shortcut?

    - by Ryan Jendoubi
    There are many questions and answers here and around the web on setting basic keyboard shortcuts in GNOME. Most of them are either for launching applications, or Compiz settings, or for changing defaults for other things for which Ubuntu provides defaults shortcuts. What I want to know though is how to refer to a gnome-panel menu item in a custom keyboard shortcut. I'm using Ubuntu 11.10 with GNOME Classic, and the old GNOME 2 / Ubuntu 10.04 keyboard shortcuts for the main menus (Alt-F1) and the "Me Menu" (Super+S) don't seem to work. So my question is two-fold. Primarily I'd like to know how to set those shortcuts. But a second-order question is how I could have found this out myself: is there some program I can use to see what signals or commands are fired off when I click on various things, in this case gnome-panel menu items? I'm interested in the broader question because I've sometimes wanted to set shortcuts for specific menus or menu items in GNOME 2, so a way to find out what command I need there would be useful. Give a man a rod, as they say :-) I've had a look at a good lot of keyboard shortcut and menu related items here to no avail. One somewhat relevant question is this one, but it's just a "how do I do it" question, and applies to Unity, not GNOME, although it would be great if whatever investigatory method answers this question might also apply under different desktops, like Unity. The answer to this question is essentially how I was doing it in 10.04 / GNOME 2, although the questioner's query isn't exactly addressed - how to get directly to "Broadcast" with a key combination. Again, it would be great if an answer delving into how such menus work and how they interact with the rest of the system would be applicable to pinpoint menu items.

  • Sendmail relay out of Amazon EC2?

    - by Stephen Belanger
    I have a site running on CentOS 5.4 through Amazon EC2. Unfortunately, Amazon has had nothing but trouble with their entire IP range getting black listed from spam tracking services regularly. I need a mail server, so I setup an smtp server elsewhere that I want to send to, but I can't just send directly to it through PHP because the direct smtp request is way too slow. What I want to do is relay through sendmail, but I've never used sendmail before, so I have no idea how to configure it. All I want is for all emails sent from localhost to be relayed to one specific external server, but I don't know how to do that. I tried to find a tutorial online, but couldn't find anything that was particularly clear as to how I go about doing that. Can anyone help me out?

  • Best Architecture for ASP.NET WebForms Application

    - by stack man
    I have written an ASP.NET WebForms portal for a client. The project has kind of evolved rather than being properly planned and structured from the beginning. Consequently, all the code is mashed together within the same project and without any layers. The client is now happy with the functionality, so I would like to refactor the code such that I will be confident about releasing the project. As there seems to be many differing ways to design the architecture, I would like some opinions about the best approach to take. FUNCTIONALITY The portal allows administrators to configure HTML templates. Other associated "partners" will be able to display these templates by adding IFrame code to their site. Within these templates, customers can register and purchase products. An API has been implemented using WCF allowing external companies to interface with the system also. An Admin section allows Administrators to configure various functionality and view reports for each partner. The system sends out invoices and email notifications to customers. CURRENT ARCHITECTURE It is currently using EF4 to read/write to the database. The EF objects are used directly within the aspx files. This has facilitated rapid development while I have been writing the site but it is probably unacceptable to keep it like that as it is tightly coupling the db with the UI. Specific business logic has been added to partial classes of the EF objects. QUESTIONS The goal of refactoring will be to make the site scalable, easily maintainable and secure. 1) What kind of architecture would be best for this? Please describe what should be in each layer, whether I should use DTO's / POCO / Active Record pattern etc. 2) Is there a robust way to auto-generate DTO's / BOs so that any future enhancements will be simple to implement despite the extra layers? 3) Would it be beneficial to convert the project from WebForms to MVC?

  • Gnome3 shell video corruption with ATI Radeon HD 4850 on 11.10 Oneiric

    - by AndyAtTheWebists
    I have a problem similar to what's been mentioned in a few other questions, namely: Ati incompatible with Gnome-shell? Gnome Shell Glitched Top Bar Ubuntu 11.10 I have read a number of other posts here and on other forums and have tried a bunch of different solutions. The Problem The problem manifests itself only in Gnome3. I have tried KDE, Unity and KFCE and all are fine. The graphics corruption is visible only on gnome panels (see images below). Everything works fine with the free ATI drivers, but they just lack power. The problem occurs with the proprietary ones from AMD/ATI. I have installed version 11.11 and 12.1 as per the instructions on wiki.cchtml.com/index.php/Ubuntu_Oneiric_Installation_Guide. I have the same exact problem in both cases. I have tried this on clean installs of Ubuntu 11.10 Oneiric Ocelot (x64 and x86) and on Linux Mint 12 (x64) with the same results. Also, it looks like after some time of not using it, the PC just freezes. Maybe an overheat? Will look into it. Things I've Tried I have tried the following fixes: Different versions of drivers from ATI including the latest - this worked for some, not for me. Installing Oneiric specific package generated from driver, as well as the default install Removed the Unity Global menu Disabled file manager handling desktop Disabled Compiz "detect refresh rate" Sync to VBlank in Compiz on and off Please help! This is the first time in 10 years that I've finally had the chance to switch my primary desktop to Linux (stopped doing .NET dev work), and this is really getting me down. This is what the problem looks like: And:

  • Meraki's Accounting-Requests to RADIUS server

    - by PachinSV
    I'm running a RADIUS server with some Meraki APs, the process of Authentications is fine... But it seems that the Meraki Cloud Controller is just sending the authentication packets and not the accounting requests. I've tested the RADIUS sending accounting requests with the radclient tool (locally) and it worked. I think that maybe my RADIUS server is ignoring the accounting requests from the MCC because there are some Vendor Specific Attributes that my RADIUS doesn't know. should I add a Meraki's dictionary to my RADIUS configurations? I'm kind of desperate, any idea?

  • Can I block social share buttons with Privoxy?

    - by gojira
    A great many pages have these "Like", "Tweet", "G+1", "share" row of buttons all over the place and in each post in threads. Can I block these unwanted context with Privoxy? I am already using Privoxy and it blocks a lot of unwanted content, but still these "social" buttons are all over the place. I want to completely remove these buttons specifically by using Privoxy. I know that it is possible to block using AdBlock LITE and other software, but my question is specific to Privoxy (reason, I want one point to block all unwanted content and it needs to work on devices / softwares which do not have AdBlock LITE, therefore I use Privoxy). -- Software used: Privoxy 3.0.21 under Windows XP

  • Recovering from an incorrectly deployed robots.txt?

    - by Doug T.
    We accidentally deployed a robots.txt from our development site that disallowed all crawling. This has caused traffic to dip dramatically, and google results to report: A description for this result is not available because of this site's robots.txt – learn more. We've since corrected the robots.txt about a 1.5 weeks ago, and you can see our robots.txt here. However, search results still report the same robots.txt message. The same appears to be true for Bing. We've taken the following action: Submitted site to be recrawled through google webmaster tools Submitted a site map to google (basically doing everything possible to say "Hey we're here! and we're crawlable!") Indeed a lot of crawl activity seems to be happening lately, but still no description is crawled. I noticed this question where the problem was specific to a 303 redirect back to a disallowed path. We are 301 redirecting to /blog, but crawling is allowed here. This redirect is due to a site redesign, wordpress paths for posts such as /2012/02/12/yadda yadda have been moved to /blog/2012/02/12. We 301 redirect to wordpress for /blog to keep our google juice. However, the sitemap we submitted might have /blog URLs. I'm not sure how much this matters. We clearly want to preserve google juice for URLs linked to us from before our redesign with the /2012/02/... URLs. So perhaps this has prevented some content from getting recrawled? How can we get all of our content, with links pointed to our site from pre-and-post redesign reporting descriptions? How can we resolve this problem and get our search traffic back to where it used to be?

  • How do I create a folder name that starts with a dot in Windows 7?

    - by Jim Tough
    I'm on a Windows 7 machine and need to create a new folder whose name starts with a dot. To be specific, I need to create the folder "C:\USERS\theusername\.ec2" because that is the default location that the AWS plugin for Eclipse likes to find certain configuration files. Windows 7 gives me an error message whenever I try to create a folder that starts with a dot: You must type a filename Seriously? There are already subfolders in this folder that start with a dot! How can I tell Windows 7 to just shut up and create my folder?

  • Modular Web App Network Architecture

    - by nairware
    Assuming that I am dealing with dedicated physical servers or VPSs, is it conceivable and does it make sense to have distinct servers setup with the following roles to host a web application? Reverse Proxy Web server Application server Database server Specific points of interest: I am confused how to even separate the web and application servers. My understanding was that such 3-tier architectures were feasible. It is unclear to me if the app server would reside directly between the web and database server, or if the web server could directly interact with the database as well. The app server could either do the computational heavy-lifting on behalf of the app server or it could do heavy-lifting plus control all of the business logic (as implied in the diagram above, thus denying the web server of direct database access). I am also unsure what role the reverse proxy (ex. nginx) could and should fulfill as a web server, given the above mentioned setup. I know that nginx has web server features. But I do not know if it makes sense to have the reverse proxy be its own VPS, given that the web server–in theory–would be separate from the app server.

  • Wiki Application With A Reputation System

    - by Christofian
    I'm really impressed with Stack Exchange's concept of reputation (you gain reputation as you post, and the more you post, the more privileges you get), and I want to apply the concept to a wiki that I am building. Does anyone know of a php wiki that has a concept of privileges/reputation similar to Stack Exchange? I'm not necessarily looking for something identical to SE, I'm just looking for a wiki application that gives users more privileges the more they contribute positively to the wiki (SE has down votes, the wiki should have some way of identifying negative contributions too). The privileges should be category based, so the more active you are in a specific category or page, the more privileges you get for that category. There should also be site wide privileges as well, though those should be harder to access than the category privileges. NOTE: If it is not possible to get category wide privileges and site wide privileges, I will be OK with just category wide privileges or just site wide privileges. I should be able to change the requirements for each privilege, through a administration panel or through editing a file (some wiki applications don't have administration interfaces). Does anyone have a script or a solution that will do this? If the script uses something similar to reputation to determine how much a user has positively contributed to the site, then that is OK too. Please Note: I am looking for a way to rate individual user contributions, not a way to rate the quality of an entire page.

  • Sound in Ubuntu 12.10 on Chromebook

    - by Paul Mennega
    I've got an HP Chromebook 14 that I've rooted and installed Ubuntu via Crouton (upgraded to 12.10) and most things are working nicely. One issue that I am having trouble solving relates to sound. I've got sound output that I can control via the individual app (e.g. Youtube), but when trying to control the volume via the built-in xfce4-mixer, I get the following error: GStreamer was unable to detect any sound devices. Some sound system specific GStreamer packages may be missing. It may also be a permissions problem. Opening a terminal, I can run the alsamixer and control the volume levels. It is reporting back that the card is CRAS. I'd love to be able to do it from XFCE and the built-in mixer. I've tried re-installing the GStreamer packages, but no luck. It seems like I am close but not sure where to go from here. On a maybe unrelated note, plugging headphones into the headphone jack in Ubuntu also does not stop the sound from coming from the speakers and nothing comes through the headphones. Switching back to ChromeOs, everything works as expected, so I think that it's a driver issue.

  • Google Analytics: How long does it take users to trigger an event

    - by Stephen Ostermiller
    I implemented Google Analytics event tracking on my currency conversion website. The typical user flow is: User lands on a page about two currencies. User enters an amount to be converted. The site shows the user the value in the other currency. The JavaScript sends Google Analytics an "converted" event when the currency conversion is done. Because most of the sessions on my site are single page, the event tracking is very important to me to be able to know if users find my page useful. I'm looking for a way to be able to figure out how long it typically takes users to enter a value in the form. I expect that this data would form a bell curve with around a specific amount of time after page load. If I can't get a graph, I could make do with a median value. I would like to be able to use this as a core metric around usability testing. Is there a way to get this information out of Google Analytics?

  • Is there a shell-independent HUD-like menu search tool for Xfce/GNOME/Cinnamon?

    - by Redsandro
    The Ubuntu Heads-Up Display (HUD) - you love it or you hate it. Personally I rather like a classic desktop, so I use Xfce or GNOME-fork Cinnamon, and I'd like to keep those menu's where they are. But the HUD is pretty awesome when your menus are complex and you forgot where an option sits. This makes that search trick very interesting. I know the HUD is Unity specific. I am looking for a HUD-like tool to complement the menu in shells other than Unity. There is Appmenu Runner for KDE that does this. There is also appmenu-qt for KDE. Problem with the above is that it uses KDE libs, and it only works for KDE apps. This is Linux, there aught to be something like this for GNOME/GTK apps, right? Looking for any tool that can search the menus. I already use(d) Synapse, Kupfer and GNOME Do, but those are simply app-launchers (with some tricks). Something like that would suffice if only they included searching the menus for the currently focused application. The HUD allows users to activate menu items by typing part of the name. It uses a fuzzy search algorithm that will highlight partial matches. It can match menu items that are multiple layers deep in an application's menu hierarchy. The feature, which replaces traditional menu accelerators, is activated by pressing the alt key. Similar questions: Is there a way to search a menu bar in Debian? - Unix.StackExchange How can I access menu bar items alike hud (unity)? - Unix.StackExchange HUD in other window managers (especially xmonad) - AskUbuntu

  • Accessing SQL Server data from iOS apps

    - by RobertChipperfield
    Almost all mobile apps need access to external data to be valuable. With a huge amount of existing business data residing in Microsoft SQL Server databases, and an ever-increasing drive to make more and more available to mobile users, how do you marry the rather separate worlds of Microsoft's SQL Server and Apple's iOS devices? The classic answer: write a web service layer Look at any of the questions on this topic asked in Internet discussion forums, and you'll inevitably see the answer, "just write a web service and use that!". But what does this process gain? For a well-designed database with a solid security model, and business logic in the database, writing a custom web service on top of this just to access some of the data from a different platform seems inefficient and unnecessary. Desktop applications interact with the SQL Server directly - why should mobile apps be any different? The better answer: the iSql SDK Working along the lines of "if you do something more than once, make it shared," we set about coming up with a better solution for the general case. And so the iSql SDK was born: sitting between SQL Server and your iOS apps, it provides the simple API you're used to if you've been developing desktop apps using the Microsoft SQL Native Client. It turns out a web service remained a sensible idea: HTTP is much more suited to the Big Bad Internet than SQL Server's native TDS protocol, removing the need for complex configuration, firewall configuration, and the like. However, rather than writing a web service for every app that needs data access, we made the web service generic, serving only as a proxy between the SQL Server and a client library integrated into the iPhone or iPad app. This client library handles all the network communication, and provides a clean API. OSQL in 25 lines of code As an example of how to use the API, I put together a very simple app that allowed the user to enter one or more SQL statements, and displayed the results in a rather primitively formatted text field. The total amount of Objective-C code responsible for doing the work? About 25 lines. You can see this in action in the demo video. Beta out now - your chance to give us your suggestions! We've released the iSql SDK as a beta on the MobileFoo website: you're welcome to download a copy, have a play in your own apps, and let us know what we've missed using the Feedback button on the site. Software development should be fun and rewarding: no-one wants to spend their time writing boiler-plate code over and over again, so stop writing the same web service code, and start doing exciting things in the new world of mobile data!

  • Generalist Languages: Dying or Alive and Well?

    - by dsimcha
    Around here, it seems like there's somewhat of a consensus that generalist programming languages (that try to be good at everything, support multiple paradigms, support both very high- and very low-level programming), etc. are a bad idea, and that it's better to pick the right tool for the job and use lots of different languages. I see three major areas where this is flawed: Interfacing multiple languages is always at least a source of friction and is sometimes practically impossible. How severe a problem this is depends on how fine-grained the interfacing is. Near the boundary between the two languages, though, you're basically limited to the intersection of their features, and you have to care about things like binary interfaces that you usually wouldn't. Passing complex data structures (i.e. not just primitives and arrays of primitives) between languages is almost always a hassle. Furthermore, shifting between different syntaxes, different conventions, etc. can be confusing and annoying, though this is a fairly minor complaint. Requirements are never set in stone. I hate picking a language thinking it's the right tool for the job, then realizing that, when some new requirement surfaces, it's actually a terrible choice for that requirement. This has happened to me several times before, usually when working with languages that are very slow, very domain specific and/or has very poor concurrency/parallelism support. When you program in a language for a while, you start to build up a personal toolbox of small utility functions/classes/programs. The value of these goes drastically down if you're forced to use a different language than the one you've accumulated all this code in. What am I missing here? Why shouldn't more focus be placed on generalist languages? Are generalist languages as a category dying or alive and well?

  • New Feature! Automatic Categories for Geekswithblogs.net

    - by Jeff Julian
    One of the features we have been working on is a way to categorize posts without the need of all our bloggers getting on the same page with what categories we have and making them select the categories.  Johnny Kauffman, one of our team members at AJI Software, developed what we call the Sherlock Project over the past few months.  Sherlock is a category suggestion engine based on the content within the posts.  Now, after a post is published, Sherlock will investigate the content and come up with the suggested categories that content fits in.  This will now allow you to go to the specific topics you are interested in and see all the related posts. This is just the beginning, so many more opportunities will arise now that we have our content organized.  One of the first features I will be adding is RSS feeds for each category and sub category.  If you are into ALM, we will have a feed for that! I hope you enjoy these and the engine will continue to get better as we start testing the data.  I hope you are as excited about this as I am :D.  Technorati Tags: Geekswithblogs.net,Categories,Sherlock

  • Windows XP Home Edition SP3 cant recognise PCMIA SD Card

    - by Pozo
    System Specifications: Laptop : Dell Inspiron 6000 OS: Windows Home Edition SP3 SD Adapter: Hagiwara Smart Media Adapter I inserted the card into the slot, windows xp recognises the device, lists the pcmia controller on the device manager list, an entry appears under the IDE ATA/ATAPI category on the device manager as well. However, the device does not show under my computer and the driver does not get assigned a letter number. I checked the system logs from the device manager and there were no logged errors. Checking the Hagiwara support website, the manufacturer indicates that the adapter driver is the same as the windows xp pcmia controller. Checking Dell's website, no specific drivers were listed for that either. General Search on the web indicates that multiple people face similar problems with their SD cards, yet none actually spell out the route issue that causes this. Please let me know if you have any suggestions for further debugging. Thanks in advance

  • Two Routers, Two Internet (1 Open, 1 PPTP) - Routing?

    - by SomeUser
    Hi there, I'm trying to setup two routers - one to route specific sites to a always-on PPTP VPN connection, the other for open internet access w/ firewall. First router is connected to Internet w/ built-in firewall. Second router is connected to a PPTP VPN connection. I was going to connect a wire between the routers and would like some insight on how to get both groups of systems (connected to each router) to talk between automatically. Even better would be to setup one gateway for certain sites and another for general Internet. The other option is to default all sites to the net and shoot others to the gateway or vice versa... Any insight so I can get a better grasp of this? Thanks!

  • ubuntu12.04 hangs at checking battery state

    - by crystalbass17
    My 12.04 system hangs at "Checking battery state". At this stage, no commands work eg: ctrl+alt+f1, alt+f5. I ran recovery mode, I ran the command sudo mount -o remount, rw sudo dpkg-reconfigure gdm and gdm was the only one installed so I didn't get a GUI screen. I have an integrated graphics card "Intel Corporation Mobile 4 chipset Integrated Graphics Controller (rev 07)". So I cannot install nvidia drivers as everyone else suggests. I have gone through several similar questions but everyone suggests reconfiguring gdm or reinstalling graphic drivers. I did sudo add-apt-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update sudo apt-get upgrade to get the latest x-swat drivers. The system still hung at the same line. The other option is to reinstall ubuntu, which is out of the question, since we have a very specific install for our project where the settings are very hard to duplicate. Suggestions/Comments welcome.

  • Date header returned by IIS7 is wrong

    - by James Hollingworth
    I am serving an ASP.NET application from IIS 7 but we are experiencing some weird cookie issues. The code works fine in other environments so we are assuming this is specific to this server (related question). We have been looking at the http headers returned and someone pointed out that the date http header is showing the 1st of Jan rather than today's date (so far it always shows that date regardless of what the current date is). The system clock is set correctly (and we can print out the current time/date via DateTime.Now correctly as well) so we can't work out why it's now working. Does anyone have any ideas? Is this a red-herring? Thanks, James

  • Microeconomical simulation: coordination/planning between self-interested trading agents

    - by Milton Manfried
    In a typical perfect-information strategy game like Chess, an agent can calculate its best move by searching the state tree for the best possible move, while assuming that the opponent will also make the best possible move (i.e. Mini-max). I would like to use this approach in a "game" modeling economic activity, where the possible "moves" would be to buy or sell for a given price, and the goal, rather than a specific class of states (e.g. Checkmate), would be to maximize some function F of the agent's state (e.g. F(money, widget) = 10*money + widget). How to handle buy/sell actions that require coordination between both parties, at the very least agreement upon a price? The cheap way out would be to set the price beforehand, maybe based upon the current supply -- but the idea of this simulation is to examine how prices emerge when freely determined by "perfectly rational" agents. A great example of what I do not want is the trading algorithm in SugarScape -- paraphrasing from Growing Artificial Societies p101-102: when a pair of agents interact to trade, they each compute their internal valuations of the goods, then a bargaining process is conducted and a price is agreed to. If this price makes both agents better off, they complete the transaction The protocol itself is beautiful, but what it cannot capture (as far as I can tell) is the ability for an agent to pay more than it might otherwise for a good, because it knows that it can sell it for even more at a later date -- what appears to be called "strategic thinking" in this pape at Google Books Multi-Agent-Based Simulation III: 4th International Workshop, MABS 2003... to get realistic behavior like that, it seems one would either (1) have to build an outrageously-complex internal valuation system which could at best only cover situations that were planned for at compile-time, or otherwise (2) have some mechanism to search the state tree... which would require some way of planning future trades. Note: The chess analogy only works as far as the state-space search goes; the simulation isn't intended to be "zero sum", so a literal mini-max search wouldn't be appropriate -- and ideally, it should work with more than two agents.
