• 12.04 64 bit: Keybord not responding for about 20 seconds at startup/beginning of session

  - by Danilo

  I am running Ubuntu 12.04 64bit. When I get at the login screen and try to type the password for my user, I cannot type anything for about 20 seconds. After that, the keyboard starts responding and everything works fine. Mouse is responding normally as well as all buttons of the login interface (time/calendar, session selection (Unity/Unity 2D), etc.). What could be the reason for this behavior? How can I solve this temporary freeze of the keyboard so that I can type my password immediately without having to wait each time? Thanks for your time. EDIT: I tried auto login, but the problem is still there: the Desktop loads but even there, if I try to type something in the dash or anywhere else, I must wait about 20 seconds before I can actually start typing. Can the issue be related to some keyboard modules that get loaded little bit "too late"?

• Super-quick MIDI generator with nonrestrictive license?

  - by Ricket

  I'm working on my Ludum Dare entry and trying to figure out how in the world I'm ever going to get background music. I found WolframTones, but the license is too restrictive: Unless otherwise specified, this Site and content presented on this Site are for your personal and noncommercial use. You may not modify, copy, distribute, transmit, display, perform, reproduce, publish, license, create derivative works from, transfer, or sell any information or content obtained from this Site.

Is there another program that does this same sort of thing but without a restrictive license, so that I can generate a bgm and use it in my game?

• Desktop dims when Thunderbird and Firefox are launched

  - by deshmukh

  I am running Ubuntu 12.04 (almost default install regularly updated) Unity interface on ASUS X53U (AMD Brazos Dual Core C60 with 2GB RAM). On launching Thunderbird and Firefox, the application dims and the cursor changes to wait mode. In case of Thunderbird, this is most pronounced with the wait time of up to a minute. Memory status checked with free indicates around 500MB of free memory on such occasions. The OS is stable and I can switch to a different work-space, etc. What could this be? Is this something normal?

• How to set up bridged networking in Xen?

  - by Joe Carr

  I have 2 domU virtual machines installed on a 11.10 Oneiric Dom0. My internal network is on the 192.168.1 subnet, and when the domU's start, they get ips on the 192.168.122 subnet. I have attempted to follow the instructions here : http://wiki.kartbuilding.net/index.php/Xen_Networking xend-config.sxp is configured correctly, but neither of my domU's have a config file in /etc/xen to modify. ifconfig reports that I have the following devices : eth0, lo, tap3.0, vif3.0, vif4.0, virbr0 bridge-utils is installed. I also just attempted to follow these steps : http://serverfault.com/questions/233201/bringing-the-xenbr0-interface-up-on-xen-under-ubuntu-8-04 sudo brctl addbr xenbr0 sudo brctl addif xenbr0 vif3.0 device vif3.0 is already a member of a bridge; can't enslave it to bridge xenbr0. Any ideas on next steps are greatly appreciated!

• Let a model instance choose appropriate view class using category. Is it good design?

  - by Denis Mikhaylov

  Assume I have abstract base model class called MoneySource. And two realizations BankCard and CellularAccount. In MoneysSourceListViewController I want to display a list of them, but with ListItemView different for each MoneySource subclass. What if I define a category on MoneySource @interface MoneySource (ListItemView) - (Class)listItemViewClass; @end And then override it for each concrete sublcass of MoneySource, returning suitable view class. @implementation CellularAccount (ListItemView) - (Class)listItemViewClass { return [BankCardListView class]; } @end @implementation BankCard (ListItemView) - (Class)listItemViewClass { return [CellularAccountListView class]; } @end so I can ask model object about its view, not violating MVC principles, and avoiding class introspection or if constructions. Thank you!

• Building Enterprise Smartphone App &ndash; Part 2: Platforms and Features

  - by Tim Murphy

  This is part 2 in a series of posts based on a talk I gave recently at the Chicago Information Technology Architects Group.  Feel free to leave feedback. In the previous post I discussed what reasons a company might have for creating a smartphone application.  In this installment I will cover some of history and state of the different platforms as well as features that can be leveraged for building enterprise smartphone applications. Platforms Before you start choosing a platform to develop your solutions on it is good to understand how we got here and what features you can leverage. History To my memory we owe all of this to a product called the Apple Newton that came out in 1987. It was the first PDA and back then I was much more of an Apple fan.  I was very impressed with this device even though it never really went anywhere.  The Palm Pilot by US Robotics was the next major advancement in PDA. It had a simple short hand window that allowed for quick stylus entry.. Later, Windows CE came out and started the broadening of the PDA market. After that it was the Palm and CE operating systems that started showing up on cell phones and for some time these were the two dominant operating systems that were distributed with devices from multiple hardware vendors. Current The iPhone was the first smartphone to take away the stylus and give us a multi-touch interface.  It was a revolution in usability and really changed the attractiveness of smartphones for the general public.  This brought us to the beginning of the current state of the market with the concept of an online store that makes it easy for customers to get new features and functionality on demand. With Android, Google made this more than a one horse race.  Not only did they come to compete, their low cost actually made them the leading OS.  Of course what made Android so attractive also is its major fault.  It is so open that it has been a target for malware which leaves consumers exposed.  Fortunately for Google though, most consumers aren’t aware of the threat that they are under. Although Microsoft had put out one of the first smart phone operating systems with CE it had to play catch up and finally came out with the Windows Phone.  They have gone for a market approach between those of iOS and Android.  They support multiple hardware vendors like Google, but they kept a certification process for applications that is similar to Apple.  They also created a user interface that was different enough to give it a clear separation from the other two platforms. The result of all this is hundreds of millions of smartphones being sold monthly across all three platforms giving us a wide range of choices and challenges when it comes to developing solutions. Features So what are the features that make these devices flexible enough be considered for use in the enterprise? The biggest advantage of today's devices is network connectivity.  The ability to access information from multiple sources at a moment’s notice is critical for businesses.  Add to that the ability to communicate over a variety of text, voice and video modes and we have a powerful starting point. Every smartphone has a cameras and they are not just useful for posting to Instagram. We are seeing more applications such as Bing vision that allow us to scan just about any printed code or text to find information.  These capabilities have been made available to developers in the form of standard libraries for reading barcodes of just about an flavor and optical character recognition (OCR) interpretation. Bluetooth give us the ability to communicate with multiple devices. Whether these are headsets, keyboard or printers the wireless communication capabilities are just starting to evolve.  The more these wireless communication protocols grow, the more opportunities we will see to transfer data between users and a variety of devices. Local storage of information that can be called up even when the device cannot reach the network is the other big capability.  This give users the ability to work offline as well and transmit information when connections are restored. These are the tools that we have to work with to build applications that can be leveraged to gain a competitive advantage for companies that implement them. Coming Up In the third installment I will cover key concerns that you face when building enterprise smartphone apps. del.icio.us Tags: smartphones,enterprise smartphone Apps,architecture,iOS,Android,Windows Phone

• How to increase the bus factor and specialize at the same time?

  - by bizso09

  In agile pair programming it is recommended to switch pairs every now and then so as to increase the bus factor of the team. That means, most people in the team should work on different parts of the system at different times so that everyone has an understanding of it. Now it is impssible that everyone has an expert level of understanding of each part of the system. That's because people are urged to specialize in one area of expertise. If you are an expert database admin, what's the point of working on the user interface of the system when you switch pairs? You will not be able to do such a high quality job as someone who has extensive experience in UI design. How can you increase the bus factor and make sure that you have specialization in your team?

• How to adjust DPI in 14.04

  - by jake

  I asked about fixing DPI in 12.04. The 14.04 release notes list "Support for High-DPI screens and desktop scaling." Post upgrade, it seems that nothing has changed. Similar symptoms from my previous post persist: The 1" square here is closer to 1/2" Despite the line xserver-command=X -dpi 170 in /etc/lightdm/lightdm.conf, xdpyinfo reports 96x96 dpi I did find that I was able to use the "Scale for menu and title bars" slider in System SettingsDisplays to fix title bar text size instead of setting org.gnome.desktop.interface text-scaling-factor as described here. The last post also mentions that in Gnome 3, DPI is hard coded to 96. Is this a limitation in 14.04? (I am somewhat ignorant to the distinction between Gnome and Unity) Can I do anything to properly set my DPI?

• Minimum to install for a visual web browser in Ubuntu Server

  - by Svish

  I have set up a machine with Ubuntu Server. Some of the server software I want to run on it has web based user interfaces for setting it up et cetera. I know I could connect to it from a different machine which has a graphical user interface, but in this case I would rather do it on the box. So, from a fresh Ubuntu Server installation, what is the minimum I need to install to be able to launch a web browser I can use for this? For example chromium, firefox or arora.

• How does timeseal work? [on hold]

  - by Simon Meyer

  I know the the fics (free internet chess server: www.freechess.org/) does use a program called timeseal to measure the time that a user needed to take a move. This timeseal is some time measurement on the client. Measuring on the client is much better and fairer than measuring the time on the server since you don't lose time just by having a bad connection. But since fics has a lot of interfaces to play on - what prevents rogue interfaces to say that they always only used 0.1 seconds for any move? Does anyone know how this is handled? Just a sidenote: i don't want to build a rogue interface, but i'm trying to build something similar that is measuing client side time but should not be easy to cheat on.

• 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?

• 6 Start Menu Replacements for Windows 8

  - by Chris Hoffman

  Want a Start menu on your Windows 8 desktop? While Microsoft no longer includes the Start button, opting instead for a click in a hidden corner and a new Start screen, there are quite a few Start menu replacements you can choose from. You can try living without the Start button and customizing your Start screen – it’s very possible to get by without the Start button and some people seem to prefer the new interface – but you have a choice. Many of these tools also allow you to boot directly to the desktop and hide the charms and app switcher that appear when you move your cursor to the corners of the screen, giving you a more traditional desktop experience.

• PeopleSoft Grants & the Federal Agency Letter of Credit Draw Changes

  - by Mark Rosenberg

  For decades, most, if not all, US Federal agencies that sponsor research allowed grant recipients to request and receive payments using pooled accounts, commonly known as pooled letter of credit (LOC) draws. This enabled organizations, such as universities and hospitals, fast and efficient access to reimbursement of the expenditures they incurred conducting research across a portfolio of grants. To support this business practice, the PeopleSoft Grants solution has delivered an LOC Draw report to provide the total request amount along with all of the supporting invoice details for reconciliation and audit purposes. Now, in an attempt to provide greater transparency, eliminate fraud, strengthen accountability for grant-related financial transactions, and simplify grant award closeout, many US Federal sponsors are transitioning from the “pooling” letter of credit draw method to requesting on a “grant-by-grant” basis. The National Science Foundation, the second largest issuer of Federal awards, already transitioned to detailed grant draws in 2013. And, in response to the U.S. Department of Health and Human Services (HHS) directive to HHS-supported Agencies, the largest Federal awards sponsor, the National Institutes of Health (NIH), will fully transition to the new HHS subaccount draw method. This will require NIH award recipients to request payments based on actual expenses incurred on an award-by-award basis. NIH is expected to fully transition to this new draw method by the end of Federal fiscal year 2015.  (The NIH had planned to fully transition to this new method by the end of fiscal 2014; however, the impact to institutions was deemed to be significant enough that a reprieve was recently granted.) In light of these new Federal draw requirements, we have recently released these new features to aid our customers on both PeopleSoft Grants releases 9.1 and 9.2:1. Federal Award Identification Number on the Proposal and Award Profile 2. Letter of credit fields on contract lines to support award basis draws and comply with Federal close out mandates3. Process to produce both pro forma and final LOC Draw Reports in BI Publisher report format4. Subacccount ID field on the LOC Summary and a new BI Publisher version of the LOC Summary report 5. Added Subaccount Field and contract info to be displayed on the LOC summary page6. Ability to generate by a variety of dimensions pro forma and invoiced draw listings 7. Queries for generation and manipulation of data to upload into sponsor payment request systems and perform payment matching8. Contracts LOC Close Out query to quickly review final balances prior to initiating final draws and preparing Federal Financial Reports prior to close The PeopleSoft Development team actively monitors this and other major Federal changes and continues working closely with the Grants Product Advisory Group of the Higher Education User Group to ensure a clear understanding of what our customers need in order to transition to new approaches for doing business with the Federal government. For more information regarding the enhancements to the PeopleSoft Grants solution, existing customers can login to My Oracle Support and review the Enhancements to Letter of Credit Process (Doc ID 1912692.1) associated with resolution ID 904830. This enhanced LOC functionality is available in both PeopleSoft FSCM 9.1 Bundle #31 and PeopleSoft FSCM 9.2 Update Image 8.

• Problems with NAT Adapater since upgrade to Ubuntu 12.10

  - by jjesse

  I was running Ubuntu 12.04 w/ VirtualBox installed. I was using the NAT interface to connect to everything. Basically running VBOX for testing some things and a Windows VM for Netflix.. Was back to working in my VMs today and noticed that I was unable to connect to the internet. In the VM settings I'm using the NAT adapter, however I noticed there is no NAT adapter in the Network Settings under Preferences in VBOX. Not quite sure what happened but wonder what is going on? I noticed there are some posts about changes DNSMASQ and configuring a bridge mode, but this worked out of the box under 12.04 and since the upgrade this no longers work. Need some help please

• How to use PostgreSQL on AWS - Ubuntu 11.10

  - by That1Guy

  I'm extremely new to cloud-computing, Linux, and PostgreSQL, so if this is a stupid question, I apologize. I've managed to create an m1.large instance running Ubuntu 11.10, connect via Putty SSH, and install PostgreSQL (sudo apt-get install postgresql), but that is as far as I've gotten. My goal is to run several python web-scraping scripts that I've written on this instance (so as not to eat up all of our bandwidth (smaller company at the moment)) and insert the scraped data into a PostgreSQL table on the instance and later retrieve that data to store on our local server (as I've heard AWS EBS is unreliable and I don't want to take chances). How can I configure PostgreSQL on my AWS instance? How can I access the data from my machine? I currently use PgAdmin3 to manage PosgreSQL on our local server. Can I use this same interface to manage PostgreSQL on my AWS instance? Any suggestions, solutions, links, etc is greatly appreciated. And again, if this is a dumb question, I apologize.

• How do I disable the calendar events section in GNOME Shell's clock applet?

  - by Victor

  I'm running gnome-shell 3.2.0 and when I click the clock applet in the middle of the top panel, the following shows up: I have no need for the entire right part, right of the dotted line, which is dedicated to the "Online Accounts" integration with evolution's calendar. Is there a way to remove/disable it, so I can just have the date part of the calendar applet (left of the dotted vertical line)? I just like to browse the dates to see how many days are left in the month and stuff like that. I use Google's web interface for my "Calendaring".

• Is hierarchical product backlog a good idea in TFS 2012-2013?

  - by Matías Fidemraizer

  I'd like to validate I'm not in the wrong way. My team project is using Visual Studio Scrum 2.x. Since each area/product has a lot of kind of requirements (security, user interface, HTTP/REST services...), I tried to manage this creating "parent backlogs" which are "open forever" and they contain generic requirements. Those parent backlogs have other "open forever" backlogs, and/or sprint backlogs. For example: HTTP/REST Services (forever) ___ Profiles API (forever) ________ POST profile (forever) _______________ We need a basic HTTP/REST profiles' API to register new user profiles (sprint backlog) Is it the right way of organizing the product backlog? Note: I know there're different points of view and that would be right for some and wrong for others. I'm looking for validation about if this is a possible good practice on TFS with Visual Studio Scrum.

• What algorithms can I use to detect if articles or posts are duplicates?

  - by michael

  I'm trying to detect if an article or forum post is a duplicate entry within the database. I've given this some thought, coming to the conclusion that someone who duplicate content will do so using one of the three (in descending difficult to detect): simple copy paste the whole text copy and paste parts of text merging it with their own copy an article from an external site and masquerade as their own Prepping Text For Analysis Basically any anomalies; the goal is to make the text as "pure" as possible. For more accurate results, the text is "standardized" by: Stripping duplicate white spaces and trimming leading and trailing. Newlines are standardized to \n. HTML tags are removed. Using a RegEx called Daring Fireball URLs are stripped. I use BB code in my application so that goes to. (ä)ccented and foreign (besides Enlgish) are converted to their non foreign form. I store information about each article in (1) statistics table and in (2) keywords table. (1) Statistics Table The following statistics are stored about the textual content (much like this post) text length letter count word count sentence count average words per sentence automated readability index gunning fog score For European languages Coleman-Liau and Automated Readability Index should be used as they do not use syllable counting, so should produce a reasonably accurate score. (2) Keywords Table The keywords are generated by excluding a huge list of stop words (common words), e.g., 'the', 'a', 'of', 'to', etc, etc. Sample Data text_length, 3963 letter_count, 3052 word_count, 684 sentence_count, 33 word_per_sentence, 21 gunning_fog, 11.5 auto_read_index, 9.9 keyword 1, killed keyword 2, officers keyword 3, police It should be noted that once an article gets updated all of the above statistics are regenerated and could be completely different values. How could I use the above information to detect if an article that's being published for the first time, is already existing within the database? I'm aware anything I'll design will not be perfect, the biggest risk being (1) Content that is not a duplicate will be flagged as duplicate (2) The system allows the duplicate content through. So the algorithm should generate a risk assessment number from 0 being no duplicate risk 5 being possible duplicate and 10 being duplicate. Anything above 5 then there's a good possibility that the content is duplicate. In this case the content could be flagged and linked to the article's that are possible duplicates and a human could decide whether to delete or allow. As I said before I'm storing keywords for the whole article, however I wonder if I could do the same on paragraph basis; this would also mean further separating my data in the DB but it would also make it easier for detecting (2) in my initial post. I'm thinking weighted average between the statistics, but in what order and what would be the consequences...

• Searching for an online shop accessible via API

  - by Simon A. Eugster

  I need an online shop with a custom interface (customizing items with Ajax, with a preview included). Writing it myself does not make too much sense (implementing all the payment options etc.), so I would like to use an existing online shop (OpenSource). I would like to build my own UI which, for example, tells the shop to add an item to its cart -- i.e. without using the online shop's native UI. More precisely, it should be an online gallery where the user can directly order an image if he likes it. The final checkout/payment page can be native again. Is there a shop system that supports this? Or is it still faster to write it on my own? Or are there better options?

• GestureListener's fling method doesn't get called

  - by nosferat

  I'm using SimpleGestureDetector from the libgdx-users Wiki as my InputProcessor. I set it in the created() method: Gdx.input.setInputProcess(new SimpleDirectionGestureDetector(charController)); charController is my class which implements the DirectionListener interface defined in the SimpleDirectionGestureDetector class and it is responsible for moving the player character. However the character doesn't change direction when I'm performing a fling action in any direction. I've checked and the fling() method in the SimpleDirectionGesture class doesn't get called and I have no idea why, since everything seems good. What am I doing wrong?

• How do I update the IcedTea Plugin on 12.10?

  - by Brenton Horne

  Whenever I open up the page http://www.runescape.com/game.ws? in google chrome I get the notice, "IcedTea was blocked because it is out of date" and gives me the two options of updating it or running this time. I've gone to the link attached to the option of updating it and its a wikipedia page http://icedtea.classpath.org/wiki/Main_Page that wasn't helpful for me because I didn't know what to download and install. Whenever I click, 'Run this time' it works momentarily but it is prone to have the runescape interface in the browser disappear and be replaced with a black screen.
