  • Customizing JBar for Notifications

    - by Ryan Ohs
    Lately I've been using JBar, a very neat jQuery plugin for displaying notifications in my web applications. Unfortunately the original version of JBar only supports binding to the click event of a DOM item. In order to get around this limitation I have modified the source code and posted an updated version on my GitHub account here. The modified version allows you to display a JBar notification by calling a method. I typically use it to display succes or failure messages when doing Ajax calls. I have also included some additional CSS and JS so that you can diplay different styles of notifications. showNotification(message) shows a green "success" message. showWarning(message) shows an orange "warning" message. showMessage(message, className) allows you to specify a custom class to apply to the notification for additional styling purposes. A web page with samples is included.   Get the code here.

  • I have permanent connections to Canonical servers, what are they for and how can I turn them off?

    - by Dan Dman
    After the recent upgrade to 12, I notice permanent connections to canonical servers. Running netstat -tp gives: Foreign Address State PID/Program name mulberry.canonical:http CLOSE_WAIT 6537/ubuntu-geoip-p alkes.canonical.co:http CLOSE_WAIT 6667/python alkes.canonical.co:http CLOSE_WAIT 6667/python Why are there permanent connections and how could I stop this behavior? And if this is intentional, who is responsible? I would like to understand why this was done because to me it seems like a bad idea.

  • Resources for up-to-date Delphi programming

    - by Dan Kelly
    I'm a developer in a small department and have been using Delphi for the last 10 years. Whilst I've tried to keep up-to-date with movements there are a lot of changes that have occurred between Delphi 7 and (current for us) 2010. Stack Exchange and here have been great for answering the "how do you" questions, but what I'd like is a resource that shows great examples of larger scale programming. For example is there anywhere that hosts examples of well written, multi form applications? Something that can be looked at as a whole to illustrate why things should be done a certain way?

  • My computer stops seeing the other computers on my network

    - by dan
    I'm running Ubuntu 11.04. Sometimes my computer stops seeing the names of the other computers on my network. So I can no longer log into another computer by typing the hosting name e.g. ssh [email protected] I can still log in using the local network IP address. How can I get the first way to work again without rebooting? I know this problem is local to the computer. The other computers on my network can still see one another. But they can no longer see the computer I'm working on, not even by local ip address.

  • Unity not running on startup

    - by Dan
    OK, so Firefox was running extremely slow, I ran it in safe mode and still slow, so I rebooted and when she came back on, I wasn't at the regular Unity login, it was like a classic Windows login (where I had to enter my username and password manually, not a list of users). I logged in and only my desktop was visible (with icons and my wallpaper). Nothing else. I was able to open a terminal with Ctrl+ Alt+T and typed... sudo unity ...which got it up (albeit with the default icons on the launcher ex. I had unlocked Libre Office and it was back). In "Startup Applications..." there was absolutely nothing at all... This happens every time I reboot. Thunderbird de-synced from my Gmail but Pidgin is still connected. When I do Ctrl+Alt+L it locks the screen as normal, but I have no option to switch user. I have the only account on this computer but I cannot access the main login screen to get to my Guest account. I'm not very Ubuntu-savy, but it's pretty clear that I'm starting in some sort of safemode. I am on a fresh install of Ubuntu 12.04.1 LTS (just installed it last night).

  • The Oldest Big Data Problem: Parsing Human Language

    - by dan.mcclary
    There's a new whitepaper up on Oracle Technology Network which details the use of Digital Reasoning Systems' Synthesys software on Oracle Big Data Appliance.  Digital Reasoning's approach is inherently "big data friendly," as it leverages multiple components of the Hadoop ecosystem.  Moreover, the paper addresses the oldest big data problem of them all: extracting knowledge from human text.   You can find the paper here.   From the Executive Summary: There is a wealth of information to be extracted from natural language, but that extraction is challenging. The volume of human language we generate constitutes a natural Big Data problem, while its complexity and nuance requires a particular expertise to model and mine. In this paper we illustrate the impressive combination of Oracle Big Data Appliance and Digital Reasoning Synthesys software. The combination of Synthesys and Big Data Appliance makes it possible to analyze tens of millions of documents in a matter of hours. Moreover, this powerful combination achieves four times greater throughput than conducting the equivalent analysis on a much larger cloud-deployed Hadoop cluster.

  • Network Issues only on one network with a Broadcom BCM4312

    - by Ryan McClure
    My Ubuntu 11.10 laptop is having network connection issues...only on one network. I have a BCM4312 card and I'm using the proprietary driver. Whenever I connect to a network over wireless connection, I have no trouble except for one network. In my dorm, if I try to connect to the wireless network, it stays connected from anywhere to 30 seconds to 30 minutes before it will still be "connected" according to the indicator but there is no incoming/outgoing internet connection. This only happens in this building. Other networks with the same name at other buildings on my campus have no issue whatsoever. I took it to the tech department here and they keep claiming it's my laptop; but, if I can connect to other networks with absolutely no issues, why can't my laptop connect here? So, here's my question: Is it my laptop, or is it the network? As a side note, no one else that I know has issues on this network but one; she's running Windows 7 and I forget what kind of laptop it is. One of the people in my hall runs Ubuntu 12.04 and has no problem with the wireless. What do you all think of this?

  • Hyper-V Live Migration across Sites!

    - by Ryan Roussel
    One of the great sessions I sat in on at Tech Ed this week was stretching a Windows 2008 R2 Hyper-V  Failover Cluster across sites.  With this ability, you could actually implement a Hyper-V cluster where you could migrate or even Live Migrate VMs across sites.   With this area’s propensity for Hurricanes, this will be a very popular topic for me over the next few months. While this technology is possible today, it’s also very complicated and can be very expensive to implement.    First your WAN connection has to support the ability to trunk your VLAN across both sites in order to Live Migrate.  This means you can’t use a Layer 3 routed connection like MPLS.  It has to be a Metro Ethernet connection or "Dark Fiber”.  Dark Fiber is unused Fiber already in the ground that can be leased from  various providers. Both of these connections would allow you to trunk layer 2 across your WAN.  Cisco does have the ability to trunk layer 2 across a routed connection by muxing the traffic but this is only available in their Nexus product line which has a very steep price tag.   If you are stuck with MPLS or the like and Nexus switching is not a realistic possibility, you will have to implement a multi-subnet cluster in which case Live Migration won’t be possible.  However you can still failover VMs to the remote site with some planning and manual intervention.  The consideration here is that the VMs will be on a different subnet once migrated, so you will have to change the IP addressing of your VMs.  This also has ramifications with DNS and Name resolution to control your down time.  DHCP with Reservations for your VMs is the preferred method to achieve the IP changes as this will automate that part of the process.   Secondly, you will have to have  a mechanism to replicate your storage across both sites.  Many SAN vendors natively support hardware based synchronous and asynchronous replication.  Some even support cluster shared volumes which were introduced in 2008 R2.   If your SANs do not support this natively, there are alternative file based replication products either software based like Double Take or hardware appliance like EMC.  Be sure to check with your vendor on the support of Disk majority if you’re replicating your quorum disk between SANs.   The last consideration is the ability to maintain quorum for your cluster.  If your replication provider does not support Disk Majority through replication, you will have to explore Node Majority with File Share Witness.  This will affect your design as a 3 node cluster with 1 node at the remote site and FSW at the production site would not have the ability to maintain quorum if the production site was lost. MS best practice for this would be to implement an even node cluster with 2 nodes at  each site and the FSW at a third site.   And there you have it.  While some considerations and research goes into implementing this solution, even a multi-subnet solution would be invaluable to organizations in the implementations of “warm” DR sites.

  • Are there keylogger viruses that affect Ubuntu?

    - by Ryan McClure
    I just within the last few hours had my Amazon and Gmail accounts hijacked. Purchases were made through my Amazon account that I didn't authorize...in fact, I wasn't even in my room. According to Gmail, the IP address of when I got hijacked was where I live. Enough rambling, here's my question: are there keylogger viruses on Ubuntu? I am not sure if either i accidentally let my password out there somewhere, or maybe I have a keylogger. I'm currently installing ClamAV to scan for viruses. Any help would be absolutely appreciated.

  • SQL Script to Assign All Items to ALL Sites with Dynamics GP

mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} When setting up new items within Microsoft Dynamics GP, you will often run into the error message below which reads “This site is not assigned to the selected item.  Do you want to assign this site?”  The fix is quite simple given that you simply click the Add button below which opens up the Item Quantities Maintenance window which you will hit the save button and proceed with the entry of your Sales Order or Purchase Order.   If you have a lot of new items into GP and have just one Site ID setup, the best approach to assigning your items to a particular site is by going to the Site Maintenance Window which is located in Cards>>Inventory>>Site.  Once you are in the window below, you can click the Assign button to assign Items to the Site selected.     However, if you have you a lot of Sites and Items created, this can be quite a cumbersome and time consuming process.  For that, I have created the following SQL Script below that Assigns all Items to all Site ID’s within Microsoft Dynamics GP 2010.    declare @item varchar(100)       , @loc varchar(100)       , @ItemExist int         DECLARE

  • 3d vertex translated onto 2d viewport

    - by Dan Leidal
    I have a spherical world defined by simple trigonometric functions to create triangles that are relatively similar in size and shape throughout. What I want to be able to do is use mouse input to target a range of vertices in the area around the mouse click in order to manipulate these vertices in real time. I read a post on this forum regarding translating 3d world coordinates into the 2d viewport.. it recommended that you should multiply the world vector coordinates by the viewport and then the projection, but they didn't include any code examples, and suffice to say i couldn't get any good results. Further information.. I am using a lookat method for the viewport. Does this cause a problem, and if so is there a solution? If this isn't the problem, does anyone have a simple code example illustrating translating one vertex in a 3d world into a 2d viewspace? I am using XNA.

  • Install using a Logitech Keyboard and mouse with bluetooth dongle?

    - by Ryan
    I'm trying to install 12.10 on my system, but my mouse and keyboard are not working during installation. I use the Logitech MX5500 Bluetooth mouse+keyboard combo with a Bluetooth dongle. My keyboard and mouse work in my UEFI bios, and during the Windows 7/8 installation. My keyboard also works in the Ubuntu screen that allows me to set options, install, use the live cd, etc, before boot. I'm wondering if anyone knows a way to get this dongle working during the installation process so that I can actually install 12.10.

  • Conditions for a traditional friends system vs. open following system

    - by Dan
    I'm just curious for everyone who is developing social sites out there. When you build a method for connecting users, do you prefer to use a following-style system (follow me, you can see all of my information and I can just choose to follow you back), or instead do you choose to have a friends-style system (I have to allow you see all of my information on your homepage, even if it is open to the public, vise versa). Why and under what circumstances do you use each? How do you manage privacy between your users? Have you use another way to connect your users? Examples of what methods you've choose and how you manage the user's privacy (private by default vs open to the web) are awesome; it could show correlation and provides an actual look.

  • Rhythmbox won't import or play flac files

    - by Dan Drake
    I have a new installation of 12.04 and I just copied over all my music to the ~/Music folder. Rhythmbox found all the mp3 and ogg files, but it refuses to import flac files. They simply do not appear in my music library. If I start Rhythmbox on the command line and try to import a folder that contains flac files, absolutely nothing happens. Nothing is imported; no error messages. I have all the dependencies for Rhythmbox installed, along with all the suggested and recommended packages. I can play a flac file with gst-launch-0.10 and gst-typefind-0.10 correctly identifies flac files as audo/x-flac. Why does Rhythmbox refuse to see flac files? What can I do to find out what is happening?

  • Blueprints for Oracle NoSQL Database

    - by dan.mcclary
    I think that some of the most interesting analytic problems are graph problems.  I'm always interested in new ways to store and access graphs.  As such, I really like the work being done by Tinkerpop to create Open Source Software to make property graphs more accessible over a wide variety of datastores.  Since key-value stores like Oracle NoSQL Database are well-suited to storing property graphs, I decided to extend the Blueprints API to work with it.  Below I'll discuss some of the implementation details, but you can check out the finished product here: http://github.com/dwmclary/blueprints-oracle-nosqldb.  What's in a Property Graph?  In the most general sense, a graph is just a collection of vertices and edges.  Vertices and edges can have properties: weights, names, or any number of other traits.  In an undirected graph, edges connect vertices without direction.  A directed graph specifies that all edges have a head and a tail --- a direction.  A multi-graph allows multiple edges to connect two vertices.  A "property graph" encompasses all of these traits. Key-Value Stores for Property Graphs Key-Value stores like Oracle NoSQL Database tend to be ideal for implementing property graphs.  First, if any vertex or edge can have any number of traits, we can treat it as a hash map.  For example: Vertex["name"] = "Mary" Vertex["age"] = 28 Vertex["ID"] = 12345  and so on.  This is a natural key-value relationship: the key "name" maps to the value "Mary."  Moreover if we maintain two hash maps, one for vertex objects and one for edge objects, we've essentially captured the graph.  As such, any scalable key-value store is fertile ground for planting graphs. Oracle NoSQL Database as a Scalable Graph Database While Oracle NoSQL Database offers useful features like tunable consistency, what lends it to storing property graphs is the storage guarantees around its key structure.  Keys in Oracle NoSQL Database are divided into two parts: a major key and a minor key.  The storage guarantee is simple.  Major keys will be distributed across storage nodes, which could encompass a large number of servers.  However, all minor keys which are children of a given major key are guaranteed to be stored on the same storage node.  For example, the vertices: /Personnel/Vertex/1  and /Personnel/Vertex/2 May be stored on different servers, but /Personnel/Vertex/1-/name and  /Personnel/Vertex/1-/age will always be on the same server.  This means that we can structure our graph database such that retrieving all the properties for a vertex or edge requires I/O from only a single storage node.  Moreover, Oracle NoSQL Database provides a storeIterator which allows us to store a huge number of vertices and edges in a scalable fashion.  By storing the vertices and edges as major keys, we guarantee that they are distributed evenly across all storage nodes.  At the same time we can use a partial major key to iterate over all the vertices or edges (e.g. we search over /Personnel/Vertex to iterate over all vertices). Fork It! The Blueprints API and Oracle NoSQL Database present a great way to get started using a scalable key-value database to store and access graph data.  However, a graph store isn't useful without a good graph to work on.  I encourage you to fork or pull the repository, store some data, and try using Gremlin or any other language to explore.

The company told me to create proposal include the price how much is the application is so they can process the check for me. The person who give me this project is the company supervisor and also a former supply chain supervisor in my employer before which i work also in some of their applications back then.So i want to be fair. This is my first time to create an application as a sideline so i really never experienced pricing a software even though i am working as full time web developer in a big company.

  • QA & Testing with UPK

    - by dan.gallo(at)oracle.com
    Most customers know that UPK produces both the word and excel based test scripts for UAT. Did you know that you can use UPK for QA review and bug tracking? To use UPK for QA, create content and assign it appropriately to authorized reviewers. Then have them open the developer, use customized views to find content assigned to them quickly and check out the topics. Then they can use the topic editor to review the content and provide comments right into the bubbles or use explanation frames. It makes QA-ing content this way easier than publishing and sending out .tpcs or docs for people to review. How about UPK for bug tracking? The hardest part about fixing bugs in software is reproducing the error! When you use UPK for bug tracking, it captures the exact steps the user took that gave them the error. Now development can easily walk through the process in a simulated environment to see what might have caused it, they have a documented procedure for what generated the error and they are able to better communicate with the LOB. Also, they can update or attach the simulation\documentation to any defect management software like bugzilla or something similar -all thanks to UPK.

  • Does Bing support anything like Google's First Click Free program?

    - by Dan Fabulich
    Google has a program for webmasters called First Click Free. To implement First Click Free, you need to allow all users who find a document on your site via Google search to see the full text of that document, even if they have not registered or subscribed to see that content. The user's first click to your content area is free. However, once that user clicks a link on the original page, you can require them to sign in or register to read further. The user must be able to see the full content of a multi-page article. You can allow this by displaying all content on a single page to both Googlebot and users. Alternatively, you can use cookies to make sure that a user can visit each page of a multi-page article before being asked for registration or payment. Does Bing support anything like this?

  • My server is behind a router. How can I see my website correctly? [closed]

    - by Tokyo Dan
    I'm running a web server (Ubuntu) on my local home network. I'm behind a router. On the WAN I have a direct IP. When not on my home network and accessing my website via the WAN direct IP my website displays correctly and everything works. On my home LAN behind the router, accessing my website via the WAN direct gets me to my router's admin login page. This is normal. But... Accessing my website (via it's home LAN IP address) from another computer on my home LAN gets me to the website but the layout display is broken and clicking on any link takes me to the WAN direct IP (my router's Admin login page). How can i get my website to display properly and the links to work when accessing it from my home LAN?

  • Unable to keep the connecting using a wireless bridge

    - by dan
    I am running Ubuntu 12.04 on a dell inspiron desktop (core 2 duo) and am using wicd to manage my network/wifi. I've found that the WiFi card in the machine has trouble staying connected to my router (I believe this is a function of distance between the two), so I've taken an old Belkin F5d7231 wireless router and installed dd-wrt on it to use as a wireless bridge hoping that it will have better reception. I think everything up through the wireless bridge is working OK since I have no problems accessing the internet through it with my MacBook. The problem arises when I try to hook the ubuntu machine up to the wireless bridge. It will connect for a few minutes, but it will quickly disconnect without clear triggering event; it may be more likely to disconnect if there is a heavy traffic load going over it (could be something as simple as "cat big_text_file" in an ssh session). I've tried switching from dhclient to dhcpcd without much improvement. Here is the output from the syslog when it connects: Jun 30 17:10:08 Chicabuntu dhcpcd[28278]: wlan1: dhcpcd not running Jun 30 17:10:08 Chicabuntu dhcpcd[28278]: wlan1: exiting Jun 30 17:10:08 Chicabuntu dhcpcd[28312]: eth0: dhcpcd not running Jun 30 17:10:08 Chicabuntu dhcpcd[28312]: eth0: exiting Jun 30 17:10:08 Chicabuntu avahi-daemon[1041]: Interface eth0.IPv6 no longer relevant for mDNS.

  • Making a surface transparent from blackness of texture

    - by Dan the Man
    I am making a "halo" shader in unity using GLSL. And I've come to a roadblock. What I need to do is take a texture, like the following, and make it transparent according to the darkness of it. And I don't want a cutout, because that cuts it off at a hard edge. This line of code doesn't seem to work. gl_FragColor = texture2D( vec4( _MainTex.r, _MainTex.g, _MainTex.b, _MainTex.a), vec2(textureCoordinates));

  • Does something like this "dream" online IDE product exist?

    - by Dan Tao
    I was thinking the other day, it would be amazing if a web-based product with the following features existed: Customizable text editor with nice formatting like ACE Real-time collaborative editing like Google Docs (or the late Wave) Online multi-language compiling capabilities like Ideone.com SCM hosting and/or integration + issue management like... oh, I don't know, GitHub Clearly (considering the examples), all the desired features exist. Is there anywhere that they exist all in one product? If not, does anything come close?

  • Turn off laptop display and have monitor

    - by Ryan B
    My laptop display has stopped working and is unfixable! Anyway, I got a full HD monitor and plugged that into the HDMI port of the laptop. I have changed the power settings so that I can close the lid and still have the monitor on, and this all works. However because it is on "mirror displays", I cannot get the full 1080p resolution that the monitor supports, and when I turn off mirror displays and switch off the laptop screen, the monitor will also switch off! I'm really stuck, as I can only get the monitor to display its full resolution if I have it with the laptop screen turned on, and I dont want this because (as the laptop display does not work) things get lost on that side of the screen. HELP. (Dell Studio 1537 Monitor is Samsung SA300 Connected through HDMI Ubuntu 11.10)

  • Disneyland Inside Out on iPhone and Android

    - by Ryan Cain
    It's hard to believe October was the last time I was over here on my blog.  Ironically after getter the developer phone from Microsoft I have been knee deep in iPhone programming and for the past few weeks Android programming again.  This time I've spent all my non-working hours programming a fun project for my "other" website, Disneyland Inside Out.  Disneyland Inside Out, a vacation planning site for Disneyland in California, has been around in various forms since June 1996.  It has always been a place for me to explore new technologies and learn about some of the new trends on the web.  I recently migrated the site over to DotNetNuke and have been building out custom modules for DNN.  I've also been hacking things together w/ the URLRewrite module in IIS 7.5 to provide strong SEO optimized URLs.  I can't say all that has really stuck within the DNN model of doing things, but it has worked pretty well. As part of my learning process, I spent most of the Fall bringing Disneyland Inside Out to the iPhone.  I will post more details on my development experiences later.  But this project gave me a really great opportunity to get a good feel for Objective-C development.  After 3 months I actually feel somewhat competent in the language and iPhone SDK, instead of just floundering around getting things to work.  The project also gave me a chance to play with some new frameworks on the iPhone and really dig into the Facebook SDK.  I also dug into some of the Gowalla REST api's as well.  We've been live with the app in iTunes for just about 10 days now, and have been sitting in the top 200 of free travel apps for the past few days.  You can get more info and the direct iTunes download link on our site: Disneyland Inside Out for iPhone Since launching the iPhone version I have gotten back into Android development, porting the Disneyland Inside Out app over to Android.  As I said in my first review of iPhone vs. Android, coming from a managed code background, Android is much easier to get going with.  I just about 3 weeks total I will have about 85 - 90% of the functionality up and running in the Android app, that took probably 1.5 - 2x's that time for iPhone.  That isn't a totally fair comparison as I am much more comfortable w/ Xcode and Objective-C today and can get some of the basic stuff done much faster than I could in the fall.  Though I'd say some of the hardest code to debug is still the null pointer issues on objects that were dealloc'd too early in Objective-C.  This isn't too bad with the NSZoombies enabled for synchronous code, but when you have a lot of async, which my app does, it can be hairy at times to track exactly what was causing the issue.   I will post more details later, as I am trying to wrap up a beta of the Android app today.  But in the meantime, if you have an iPhone, iPod Touch or iPad head on over to the site and take a look at my app.

  • GPU hung when switching graphic card

    - by Lie Ryan
    I have a laptop (Dell Inspiron N4110) with a switchable graphic. $ lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 01:00.0 VGA compatible controller: ATI Technologies Inc NI Whistler [AMD Radeon HD 6600M Series] (rev ff) Normally, my laptop starts with both graphic cards enabled, which caused the laptop to turn very hot and the fan to become very noisy. I have been using a small script to disable the Radeon card. For some time, I'm quite happy with this arrangement. However, I have been having some issues with the Intel card (IGD), the Intel card often randomly hang when running OpenGL apps; and so I want to give the Radeon card (DIS) another chance. I have never been able to switch to the Radeon card, but recently, I found out that if I do a "delayed switching" (DDIS): # echo "DDIS" > /sys/kernel/debug/vgaswitcheroo/switch root@lieryan-dell-ubuntu:/sys/kernel/debug/vgaswitcheroo# cat switch 0:IGD:+:Pwr:0000:00:02.0 1:DIS: :Pwr:0000:01:00.0 then I logoff (i.e. to restart X), the screen switch to pseudo-tty and then it stuck there freezing. At this situation, mouse and keyboard stops working so I can't switch to another ptty. I tried ssh-ing from another computer to salvage logs (dmesg at that point) and whatnot; I found out that when freezing, the active graphic card is the AMD card: -- this is from ssh -- # cat switch 0:IGD: :Off:0000:00:02.0 1:DIS:+:Pwr:0000:01:00.0 but the GPU is apparently hung, looking at dmesg gives: ...

I were able to successfully recover by switching back to the Intel card and restarting X from ssh; indicating that only the Radeon card has problems switching. System info: $ uname -a Linux lieryan-dell-ubuntu 3.0.0-14-generic #23-Ubuntu SMP Mon Nov 21 20:28:43 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux $ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 11.10 Release: 11.10 Codename: oneiric The laptop also do not have the option to set graphic card at BIOS and the proprietary driver, fglrx, also have never worked; when I installed it through jockey ("Additional Drivers"), glxinfo showed that it still being rendered by Mesa, the /sys/kernel/debug/vgaswitcheroo directory has gone missing, and the driver crashes with a traceback if I use xorg.conf to tell X to use fglrx. Anyone had any idea if it is possible to use this AMD card either with the radeon or the fglrx driver? logs: dmesg
