• Unable to record sound from web browser (firefox / chromium ) using recordmydesktop

  - by thamurath

  I have to do some screencast tutorials and i am using recordmydesktop with gtk frontend to do it. I need to record also the sound and here is where i have found the problem. It took me some time, but now I can record the sound from almost every application in my desktop ... almost. I need to capture some sound from a web application using java, but when i load the page nothing appears in the playback tab of pavucontrol. I think this is the problem, because if there is no sound stream i think the recordmydesktop program thinks there is no sound to record ... the funny thing is that I can ear the sound in my speakers! I have tried with Firefox and Chromium with no success. Although I have been able to record youtube videos without problem, so it seems that java is the key here. Any suggestion or idea? P.S.: I am using Ubuntu 11.10 with this configuration. ( if more information is needed please let me know) sight i cannot post images ... so I have an audigy2 sound card using Analog Stereo Output profile. I have also an "Internal Audio" device, but i have it with the "Off" profile. In recordmydesktop-Advanced-Sound: Device = default

• Web hosting providers for businesses (with offsite backups, disaster recovery options, etc.) [closed]

  - by Harry Muscle

  Possible Duplicate: How to find web hosting that meets my requirements? I'm wondering if anyone can point me in the direction of a couple of web hosting providers that are geared towards businesses. By this I mean providers that make it easy to create daily off site backups, are aware that websites require disaster recovery options and have these in place or are able to assist with them, etc. We currently have about a dozen sites with various providers, however, I've been asked to consolidate all of these into one provider and create a full disaster recovery plan. Unfortunately it seems like most providers are geared towards average users that don't require all these extra bells and whistles that businesses need. For example, HostGator, which is a very popular and well reviewed provider, doesn't even allow you to schedule full backups, they have to be manually requested via cPanel and then downloaded once available. If anyone can point out a couple companies that might be able to help with these sorts of things that would be much appreciated. Thanks, Harry P.S. I should also add that we are hoping to stay away from having to manage our own server, we're hoping for a fully managed solution like what HostGator would offer for example.

• Access Control Service: Home Realm Discovery (HRD) Gotcha

  - by Your DisplayName here!

  I really like ACS2. One feature that is very useful is home realm discovery. ACS provides a Nascar style list as well as discovery based on email addresses. You can take control of the home realm selection process yourself by downloading the JSON feed or by manually setting the home realm parameter. Plenty of options – the only option missing is turning it off… In other words, when you setup your ACS namespace and realm and register identity provider, there is no way to keep the list of identity providers secret. An interested “user” can always retrieve all registered identity provider (using the browser or download the JSON feed). This may not be an issue with web identity providers, but when you use ACS to federate with customers or business partners, you maybe don’t want to disclose that list to the public (or to other customers). This is an adoption blocker for certain situations. I hope this feature will be added soon. In addition I would also like to see a feature I call “home realm aliases”. Some random string that I can use as a whr parameter instead of using the real issuer URI.

• Web browser downloads only open target folders - cannot open files

  - by Pavlos G.

  After installing xubuntu packages in order to check xfce, I reverted back to gnome2. During the first login, I noticed that thunar was now selected as the default file manager. Preferred applications menu is also missing now, so I could not set nautilus as the default. I removed all the xubuntu packages (including thunar) and then when I tried to open a folder, I was asked to select the default file manager - that's how I got nautilus back. The next problem I'm now facing has to do with the downloaded files from web browsers: Open and Open containing folder options produce exactly the same result. If I double-click on a file, it'll just open the containing folder, instead of opening the file with it's associated application (e.g. libreoffice writer for .doc,.odt, smplayer for .avi,.wmv, etc). The problem happens both in Firefox and Chrome. Through nautilus, all files open correctly. Up until now I've tried the following: Delete/recreate mimeTypes.rdf in my FF profile Create a new profile in FF Delete/recreate ~/.local/share/applications/mimeapps.list Already checked this similar article None of them worked. Any ideas on the issue would be appreciated.

• When is the default storage rule not really the default storage rule?

  - by Kevin Smith

  In 11g WebCenter Content (WCC) introduced dispersion rules in the vault and weblayout directory paths to better distribute content across the directories. The dispersion rule was based on dRevClassID. The only problem with this is that dRevClassID did not remain the same when you copied content from one WCC instance to another using Archiver like in a contribution-consumption scenario. This could cause problems because the web-viewable path would not be the same between the contribution and consumption instances. In the PS5 (11.1.1.6.0) release of WCC they addressed this by configuring the File Store Provider (FSP) so that all new content would use a storage rule with a dispersion rule based on dDocName, which would stay the same when content was copied to another WCC instance. To support migration from older versions of WCC they left the default storage rule unchanged and created a new storage rule called DispByContentId and made that the default storage rule for all new content. I only stumbled upon this a while back when I was trying to change the FSP configuration so that all content used a webless storage rule. I changed the default storage rule, restarted WCC, and checked in a new content item. To my surprise the new content was not created as webless. I struggled with this for a while until I noticed there were multiple storage rules defined in the FSP configuration. When I looked at the default value for the xStorageRule field in Configuration Manager, sure enough it was no longer default, but was now DispByContentId. Once I updated the DispByContentId storage rule to webless and restarted WCC all my new content was now created using the webless storage rule, just like I wanted. I noticed when I was creating this blog post that the default storage rule is also listed on the File Store Provider Information page, but I guess I didn't see that when I originally did this.

• Oracle Java Embedded Client 1.1 Released

  - by Roger Brinkley

  Yesterday an update release of Oracle Java Embedded Client (OJEC) 1.1 quietly slipped out door for general availability. Until last year it was pretty difficult to get your hands on either a Connected Limited Device Configuration (CLDC) for small devices or a Connected Device Configuration (CDC) for medium devices java implementation without a substantial initial commitment. But with the the release of OJWC (CLDC) and OJEC (CDC) last year that has changed. OJEC 1.1 is a binary distribution designed for installation on medium configurations which is a mid range processor requiring a  slow startup time, seamless upgrades, in a cost sensitive hardware environment  anywhere from 3.5mb to 8 mb. There are headless as well as headed versions available. It is intended for devices, such as Blu-­-ray Disc players, set-­-top boxes, residential gateways,VOIP phones, and similar. From a software point of view, OJEC is the Java runtime platform implementation of Connected Device Configuration (CDC v1.1, JSR-­-218), Foundation Profile (FP v1.1, JSR-­-219), and Personal Basis Profile (PBP v1.1, JSR-­-217)  and includes optional packages RMI (JSR 66), JDBC (JSR 169) and XML API for Java ME (JSR 280), and Java TV (JSR-­-927). New to this release is support for the XML API (JSR 280) and a number of bug fixes and performance enhancements, including an improved Just-in-Time (JIT) compilation for the x86 chipset architecture. The platforms supported include ArmV5, ArmV6/ArmV7, MIPS 32 74K, and X86 in headless mode. For embedded developers there are number of advantages to using Java and if you have shied away from the JavaME edition in the past I would encourage you to look into the updated version of OJEC 1.1.

• Configuring Samba to allow Use of CUPS printer

  - by Skizz

  Having trouble with samba printing. I have a CUPS printer installed on an Ubuntu 11.04 server and that works great.

• Changing Launchpad username, and How to know what sites will be affected?

  - by Daniel Clem

  I am setting up my developer profile on Launchpad, and would like to change my username so it would be same as other sites I use, as well as better reflect me as a person. (that's a much more important thing than it sounds) I want to do this now while I can, because as I understand it, once I set up a PPA it will be impossible to change it due to the username being locked into the PPA URL's to prevent breakages and other problems. But when trying to change my username, it warned me with this message. "Changing your name will change your public OpenID identifier. This means that you might be locked out of certain sites where you used it, or that somebody could create a new profile with the same name and log in as you on these third-party sites." How can I find out which sites will be locked out, and how to still change the username while preventing problems with other sites? Sorry if this is actually a question for Launchpad itself. But I don't know where to post questions like this on the Launchpad site. Edit I understand that it is an issue with OpenID. But how am I to know what sites will be affected? And how do i fix the problems this will cause? Can't I just reset the password (and as a side affect, re-establish the connection with the new username) using my email address?

• Deploy multiple emails to email providers, but without showing favouritism

  - by Ardman

  We are currently developing a new email deployment system. We have the system currently configured so that it reads a record from the database and loads the email content and deploys it to the target. Now we want to move this over to multiple threads. That is easily done, except we then hit the email providers returning SMTP codes referring to "Too many connections", or "Deferred connection". The solution to this is to have a thread open up a connection to the email provider and deploy n emails and then disconnect. We have currently configured the application so that it will support these session based email deployments. The problem is this, the database table has multiple email addresses in and they aren't grouped by email provider because that will show favouritism. We need to be able to retrieve a set number of, i.e. Hotmail, emails (@hotmail.com, @hotmail.co.uk, @live.co.uk) so that we are reducing the number of connections to Hotmail and reducing the risks of getting the "Too many connections" error. We are at the point now where we have gone round and round in circles trying to get a solution, so I thought I'd throw it out there and see if anyone has any ideas? EDIT I would like to stress that this application is not used for spamming purposes.

• How to store prices that have effective dates?

  - by lal00

  I have a list of products. Each of them is offered by N providers. Each providers quotes us a price for a specific date. That price is effective until that provider decides to set a new price. In that case, the provider will give the new price with a new date. The MySQL table header currently looks like: provider_id, product_id, price, date_price_effective Every other day, we compile a list of products/prices that are effective for the current day. For each product, the list contains a sorted list of the providers that have that particular product. In that way, we can order certain products from whoever happens to offer the best price. To get the effective prices, I have a SQL statement that returns all rows that have date_price_effective >= NOW(). That result set is processed with a ruby script that does the sorting and filtering necessary to obtain a file that looks like this: product_id_1,provider_1,provider_3,provider8,provider_10... product_id_2,provider_3,provider_2,provider1,provider_10... This works fine for our purposes, but I still have an itch that a SQL table is probably not the best way to store this kind of information. I have that feeling that this kind of problema has been solved previously in other more creative ways. Is there a better way to store this information other than in SQL? or, if using SQL, is there a better approach than the one I'm using?

• Ubuntu 12.04 slow boot on ASUS, attached with dmesg and bootchart

• Usual Suspects: Typical 3rd Party Entities in E-Commerce [closed]

  - by zharvey

  I am doing some requirements/analysis for a web app that I'd like to build (Ruby/Java developer here). This web app would have a store front, shopping cart and would need to be totally compliant with all e-com best practices. It's amazing how much non-technical info comes up when you search for phrases like "how does e-commerce work", but very little comes up in the way of technical details. As such, I'm having extreme frustration finding answers to what I consider pretty straight-forward questions. I came here because I believe this question is not off-topic; if it is, please leave a comment as to why this question does not belong here and I will happily remove it myself (upvotes if your comment can point me to the correct place for this question!). So then: What 3rd parties will I need to work with to have a modern, web-compliant e-com site? So far I can account for a payment gateway provider like Authorize.net and an SSL certificate provider like Trustwave. Any others? What other standards besides PCI compliance will I be held to (besides governing laws, of course!)? Vulnerability scans: PCI compliance requires quarterly scans: if I'm a "Level 4" (low volume) Merchant does that still apply to me? Irregardless, my backend architecture is quite huge, with web servers, app servers, database, message brokers and more. Do each of these servers need to be scanned?!? If not what servers do need to get these quarterly scans? I usually hate to ask micro-questions inside of one large one, but these are so closely-related I just felt like asking them all separately would be spamming the site with too many petty questions. Thanks in advance!

• Glue Records creation

  - by FFrewin

  I need some information on the following issue, as I would like to have it clear on my mind. I have a VPS server. All my sites hosted on this VPS are using as NameServer .gr domain, like ns1.greekdomain.gr & ns2.greekdomain.gr . The .gr domain name is a domain I own with a greek registar. Now, I want to move 2 websites with .co.uk domain names to my VPS. The co.uk domain names are registered with a UK based registar. When I went in the domain management panel, I did changed the nameservers of my domains to my ns.greekdomain.gr ns. However the panel returns an error about invalid nameservers. After digging, I found that my nameservers are not valid because they do not exist as records in the .co.uk registry. And here it starts my big trouble. The .co.uk registart tells me that I have to ask my hosting provider / .gr registar to create a new record to the .uk registry for my nameservers. The .gr registar tells me that my uk registar needs to create a new record for my ns. From Nominet (.co.uk) registry, the one employee tells me that I need to ask my uk registar, the other employee (seemed to not understand what I was asking) told me that they cannot change my nameservers for me, and she told me to contact anyone else (old hosting provider, uk registar, .gr registar) to help me with that. I can't find help from nobody. I try since the last week to transfer my websites to my VPS and I can't. So, the question is who is responsible and who is able to create glue records for my nameservers ?

• Configuration Tips for better Performance with ADF Mobile Apps

  - by SRINI INDLA

  Some tips to keep in mind to make sure ADF Mobile application's performance is optimal: 1. Select release mode in deployment profile. This is perhaps the most important thing to remember to ensure best performance for ADF Mobile Apps. Selecting this option causes the deployer to package optimized JVM and minified JS libs with the mobile app there by significantly improving the over all performance of the application. 2. For iOS you do not need to do anything else other than selecting  release mode in deploy profile. However, on Android you have to create a keystore and configure it in JDev --> Tools --> Preferences --> ADF Mobile --> Platforms : Android as shown in the snapshot below 3. Steps for generating the Keystore for Android using keytool :  4. Logging level setting in logging.properties: Make sure the log level is set to SEVERE for both framework logger as well as the application logger as follows oracle.adfmf.framework.level=SEVERE oracle.adfmf.application.level=SEVERE 5. When using SOAP WebServices with WebService Data Control make sure you select the option to copy the WSDL. This will cause the JDev to download the WSDL and all the XSDs referenced by the WSDL from the server at design time and package them with the application during deployment. This way the application does not incur the cost of downloading these resources at run time from the device.

• Globacom and mCentric Deploy BDA and NoSQL Database to analyze network traffic 40x faster

  - by Jean-Pierre Dijcks

  In a fast evolving market, speed is of the essence. mCentric and Globacom leveraged Big Data Appliance, Oracle NoSQL Database to save over 35,000 Call-Processing minutes daily and analyze network traffic 40x faster.  Here are some highlights from the profile: Why Oracle “Oracle Big Data Appliance works well for very large amounts of structured and unstructured data. It is the most agile events-storage system for our collect-it-now and analyze-it-later set of business requirements. Moreover, choosing a prebuilt solution drastically reduced implementation time. We got the big data benefits without needing to assemble and tune a custom-built system, and without the hidden costs required to maintain a large number of servers in our data center. A single support license covers both the hardware and the integrated software, and we have one central point of contact for support,” said Sanjib Roy, CTO, Globacom. Implementation Process It took only five days for Oracle partner mCentric to deploy Oracle Big Data Appliance, perform the software install and configuration, certification, and resiliency testing. The entire process—from site planning to phase-I, go-live—was executed in just over ten weeks, well ahead of the four months allocated to complete the project. Oracle partner mCentric leveraged Oracle Advanced Customer Support Services’ implementation methodology to ensure configurations are tailored for peak performance, all patches are applied, and software and communications are consistently tested using proven methodologies and best practices.

• RESTful applications logic and cross resource operations

  - by Gaz_Edge

  I have an RESTful api that allows my users to receive enquiries about their business e.g. 'I would like to book service x on date y. Is this available?'. The api saves this information as a resource to the following URI users/{userId}/enquiries/{enquiryId} The information shown when this resource is retrieved are the standard sort of things you'd expect from an enquiry - email, first_name, last_name, address, message The api also allows customers to be created for a user. The customer has a login and password and also a profile. The following URIs expose these two resources PUT users/{userId}/customers/{customerId} PUT users/{userId}/customers/{customerId}/profile The problem I am having is that I would like to have the ability to allow users to create a customer from an enquiry. For example, the user is able to offer their service on the date requested and will then want to setup a customer with login details etc to allow them to manage the rest of the process. The obvious answer would be to use a URI like users/{userId}/enquiries/{enquiryId}/convert-to-client The problem with this is is that it somewhat goes against a lot of what I've been reading about how to implement REST (specifically from the book Restful Web Services which suggests that URIs should point to resources not operations on resources). The other option would be to get the client application (i.e. the code that calls the api) to handle some of this application logic. This doesn't quite feel right to me. I have implemented in my design that the client app is fairly dumb. It knows just enough to display the results from the API, and does not contain any application logic. Would be great to hear what others views are on the best way of setting this up Am I wrong to have no application logic in the client app? How would I perform this operation purely in the REST api?

• At the Java DEMOgrounds - Java EE 7 WebSocket Early Access

  - by Janice J. Heiss

  At the packed and happening Java DEMOgrounds, I wandered over to check out Java EE Web Profile and Platform Technologies. Martin Matula, a Senior Development Manager at Oracle on the JavaEE/GlassFish team, responsible for the area of web services (including JAX-WS and JAX-RS), was demonstrating Java EE Web Profile and Platform Technologies.Matula was previewing some Java EE 7 WebSocket early access features via a group drawing application that showcases the upcoming JSR 356, “Java API for WebSocket”, which is the API for building RESTful web services and Server-Sent Events, an HTML5 feature. He emphasized that this is supported in Jersey, the reference implementation for JAX-RS, as well.“In this demo,” Matula explained, “I have a simple JavaScript front-end talking to the back-end deployed on GlassFish. It uses RESTful web services to get the list of drawings we have. I can create new drawings and the list is updated immediately using the Server-Sent Events, so the message is coming from the server to the client. Everything is getting updated live using WebSocket, which is the bi-directional communication new protocol in HTML5. This is using Project Jersey and Project Tyrus. Tyrus is the implementation of WebSocket protocol for Java. Jersey implements the RESTful APIs as well as the Server-Sent Events protocol.”

• Trouble Installing Codecs libx264 AND libmp3lame

  - by user10762

  I am trying to use OpenShot for movie making. My ideal situation is to encode for the web HD, 30 Frames Per Second, to YouTube. This works out great as OpenShot has a setting for this. The problem is when i go to use it I get: "The following formats/codecs are missing from your system: libx264 libmp3lame You will not be able to use the selected export profile. You will need to install the missing formats/codecs or choose a different export profile." I have tried using Synaptic Package Manager and I think I am installing the right "plugins/codecs" yet to no avail or success. I used the instructions found here to remedy: https://answers.launchpad.net/openshot/+faq/1040 I know this impacts OTHER video editing software (in other words it is not specific just to OpenShot). They give the same type of error message when i try to use their presets as well. So in a word "Help!"... Any info is much appreciated!!! PS - If you know of a BETTER way to do this (another software) that is appreciated too! :-D

• Best way to protect website application code

  - by Gaz_Edge

  Background I have a web application that I host on my own server. I have clients who use the application as is, but some have asked if they can host the application on their own server. This enables them to have their own URLS rather than mine. The application only forms part of their website so I'm assuming it will not be possible for my server to respond to a direct call to their domain etc To give some examples, i currently have urls like www.mydomain.com/profile, www.mydomain.com/index.php?option=someoption&view=someview&id=1 What my clients' want is www.theirdomian.com/profile, www.theirdomian.com/index.php?option=someoption&view=someview&id=1 etc Question My question is, what is the best way for me to allow them to use their own URLs with my application, without giving them all the backend source code and databases to install on their server? One way I thought would be to create a router.php file that sits on their server. The router then asks my server to output the html. The router modifies all the links etc in the html source and outputs the new html through the clients server. When a link is clicked on the clients site, the router receives the request and modifies the url to get the data from my server etc. Is this an effective way to achieve what I want, or is it way off the mark.

• Mozilla Persona to the login rescue?

  - by Matt Watson

  A lot of website now allow us to login or create accounts via OAuth or OpenID. We can use our Facebook, Twitter, Google, Windows Live account and others. The problem with a lot of these is we have to have allow the websites to then have access to our account and profile data that they shouldn't really have. Below is a Twitter authorization screen for example when signing in via Technorati. Now Technorati can follow new people, update my profile and post tweets? All I wanted to do was login to Technorati.com to comment on a post!Mozilla has just released their new solution for this called Persona. First thought is oh great another solution! But they are actually providing something a little different and better. It is based on an email address and isn't linked to anything like our personal social networks or their information. Persona only exists to help with logging in to websites. No loose strings attached.Persona is based on a new standard called BrowserID and you can read more about it here:How BrowserID Works.  The goal is to integrate BrowserID in to the browser at a deeper level so no password entry is required at all. You can tell your web browser to just auto sign in for you. I am really hoping this takes off and will look at implementing it in current projects! I would recommend researching it and lets hope it or something like it becomes a wide spread reality in the future.

• Problem in domain name of site in google search [on hold]

  - by Jayadratha Mondal

  My domain provider dont supports advanced DNS at this moment. So I have used iframe to forward to my webserver. Suppose my domain abc.com have a simple html which is opening xyz.com via Iframe. Google was showing abc.com on the search. But from last two days it is showing xyz.com, other things like description, name of the site are ok only the domain changed to xyz.com, but I want to show abc.com. When I'm typing the full domain then google showing the domain as I want. But If I type a part or any keyword then it showing that xyz.com. Anyone have any idea how to show abc.com again? EDIT: I dont know the domain name provider because its not mine. When I'm trying to set new A record its showing that "you need advanced dns to do this currently you are using simple DNS". I'm doing this from cpanel. Normally as per I know there are 3 sections. 1 domain name 2 A record 3Cname. But I dont have any domain name section.

• Allowing client to select data to return via REST interface

  - by CMP

  I have a rest service that is essentially a proxy to a variety of other services. So if I call GET /users/{id} It will get their user profile, as well as order history, and contact info, etc... all from various services, and aggregates them into one nice object. My problem is that each call to a different service has the potential to add time to the original request, so we would rather not get ALL the data ALL of the time if a particular client does not care about all of the pieces. A solution I have arrived at is to do something like this: GET /users/{id}?includeOrders=true&includeX=true&includeY=true... That works, and it allow me to do only what I need to, but it is cumbersome. We have added enough different data sources that there are too many parameters for that style to be useful. I could do something similar with a single integer and a bitmask or something, but that only makes it harder to read, and it does not feel very Restful. I could break it down into multiple calls so they would need to call /users/{id}/orders and /users/{id}/profile separately, but that sort of defeats the purpose of an aggregating proxy, who's purpose is to make clients jobs easier. Are there any good patterns that can help me return just enough data for each client, without making it too difficult for them to filter and select what they want?
