  • Pidgin script with Python/ Get Focus Signal

    - by Mr Alles
    I am creating a script in Python to integrate Pidgin with Unity (12.04), I've managed to do the counting notifications system using the Launcher API. But I dont know what event or signal is activated when the conversation window gains focus (To clear the message counter). I've tried some of the signals available on the documentation of Pidgin but none of them worked. Is there any GTK(or anything) event that is triggered when the window chat gets focus?

  • Operations Manager SQL monitoring issue?

    - by merrillaldrich
    We're in the early stages of implementing System Center Operations Manager 2007 R2, and from what I've see so far it looks really good. I am still interested to see the depth of performance counter information that it'll collect and store, but haven't been able to really dig into that just yet. There is one issue I am seeing and I don't know if others have come across this (could not find much online about it either): computing a database file free space alert rule is a little complicated, and it...(read more)

  • How do I install cinnamon and mate on ubuntu server 12.04?

    - by tenshimsm
    How do I install cinnamon and mate on ubuntu server 12.04? What are the dependencies? When I install cinnamon it doesn't start when I start the system and when I try to use it with startx command i shows a "Failed to load session "ubuntu" " error while entering the desktop GUI. With MATE it also doesn't start automatically and when I start it with startx some icons are broken and the locale appears to have some problems with the pt_BR special characters.

  • Two BULK INSERT issues I worked around recently

    - by AaronBertrand
    Since I am still afraid of SSIS, and because I am dealing mostly with CSV files and table structures that are relatively simple and require only one of the three letters in the acronym "ETL," I find myself using BULK INSERT a lot. I have been meaning to switch to using CLR, since I am doing a lot of file system querying using xp_cmdshell, but I haven't had the chance to really explore it yet. I know, a lot of you are probably thinking, wow, look at all those bad habits. But for every person thinking...(read more)

  • Oracle Partner Store (OPS) New Enhancements

    - by Kristin Rose
    Effective June 29th, Oracle Partner Store (OPS) will release the enhancements listed below to improve your overall ordering experience. v Online Transactional Oracle Master Agreement (Online TOMA) The Online TOMA enables end users to execute a transactional end user license agreement with Oracle. The new Online TOMA in OPS will replace the need for you to obtain a signed hard copy of the TOMA from the end user. You will now initiate the Online TOMA via OPS. Navigation: OPS Home > Order Tools > Online TOMA Query > Request Online TOMA> End User Contact, click “Select for TOMA” > Select Language > Submit (an automated email is sent immediately to the requestor and the end user) Ø The Online TOMA can also be initiated from the ‘My OPS’ tab. Under the Online TOMA Query section partners can track Online TOMA request details submitted to end users. The status of the Online TOMA request and the OMA Key generated (once Ts&Cs of the Online TOMA are accepted by an end user) are also displayed in this table. There is also the ability to resend pending Online TOMA requests by clicking ‘Resend’. Navigation: OPS Home > Order Tools > Online TOMA Query For more details on the Transactional OMA, please click here. v Convert Deals to Carts The partner deal registration system within OPS will now allow you to convert approved deals into carts with a simple click of a button. VADs can use Deal to Cart on all of their partners' registrations, regardless of whether they submitted on their partner's behalf, or the partner submitted themselves. Navigation: Login > Deal Registrations > Deal Registration List > Open the approved deal > Click Deal Reg ID number link to open > Click on 'Create Cart' link You can locate your newly created cart in the Saved Carts section of OPS. Links are also available from within an open deal or from the Deal Registration List. Click on the cart number to proceed. v Partner Opportunity Management: Deal Registration on OPS now allows you to see updated information on your opportunities from Oracle’s Fusion CRM opportunity management system.  Key fields such as close date, sales stage, products and status can be viewed by clicking the opportunity ID associated with the deal registration.  This new feature allows you to see regular updates to your opportunities after registrations are approved.  Through ongoing communication with Oracle Channel Managers and Sales Reps, you can ensure that Oracle has the latest information on your active registered deals. v Product Recommendations: When adding products to the Deal Registrations tab, OPS will now show additional products that you can try to include to maximize your sale and rebate. v Advanced Customer Support(ACS) Services Note: This will be available from July 9th. Initiate the purchase of the complete stack (HW/SW/Services) online with one single OPS order. More ACS services now supported online with exception of Start-Up Pack: · New SW installation services for Standard Configurations & stand alone System Software. · New Pre-production & Go-live services for Standard & Engineered Systems · New SW configuration & Platinum Pre-Production & Go-Live services for Engineered Systems · New Travel & Expenses Estimate included · New Partner & VAD volume discount supported v Software as a Service (SaaS) for Independent Software Vendors (ISVs): Oracle SaaS ISVs can now use OPS to submit their monthly usage reports to Oracle within 20 days after the end of every month. Navigation: OPS Home > Cart > Transaction Type: Partner SaaS for ISV’s > Add Eligible Products > Check out v Existing Approvals: In an effort to reduce the processing time of discount approvals, we have added a new section in the Request Approval page for you to communicate pre-existing approvals without having to attach the DAT. Just enter the Approval ID and submit your request. In case of existing software approvals, you will be required to submit the DAT with the Contact Information section filled out. v Additional data for Shipping Box Labels and Packing Slips OPS now has additional fields in the Shipping Notes section for you to add PO details. This will help you easily identify shipments as they arrive. Partners will have an End User PO field, whereas VADs will have VAR and End User PO fields. v Shipping Notes on OPS Hardware delivery Shipping Notes will now have multiple options to better suit your requirements. v Reminders for Royalty Reporting Partners: If you have not submitted your royalty report online, OPS will now send an automated alert to remind you. v Order Tracker Changes: · Order Tracker will now have a deal reg flag (Yes/No). You can now clearly distinguish between orders that have registered opportunities. · All lines of the order will be visible in the order details list. v Changes in Terminology · You will notice textual changes on some of our labels and messages relating to approval requests. “Discount Requests” has been replaced with “Approval Requests” to cater to some of our other offerings. · First Line Support (FLS) transaction type has been renamed to Support Provider Partner (SPP).

  • Time calculation between openGL update calls.

    - by Vijayendra
    In XNA, the system calls update and draw function with the time information. This contains information such as how much time has passed since last update was called. This makes easy to integrate time and do animation calculation accordingly. But I dont see any such mechanism in openGL. I see openGL requires programmers to have their own implementation which could be buggy or inefficient. Is there any standard (and efficient) code that demonstrate this practice in openGL?

  • Proxy setttings not working in Ubuntu 11.10

    - by Prakash
    I always use a proxy to connect to the internet in Windows as well as in previous versions of Ubuntu, but in Ubuntu 11.10 it seems that the proxy settings I set in the GUI are not being applied system-wide. I can access the internet in Firefox with its own proxy settings. I can access internet in the terminal (i.e. I am able to use apt-get for some small programs). But in Ubuntu software centre or update manager it is not working.

  • Apprentice Boot Camp in South Africa (Part 1)

    - by Tim Koekkoek
    By Maximilian Michel (DE), Jorge Garnacho (ES), Daniel Maull (UK), Adam Griffiths (UK), Guillermo De Las Nieves (ES), Catriona McGill (UK), Ed Dunlop (UK) The Boot Camp in South Africa was an amazing experience for all of us. The minute we landed, we were made to feel at home from our host Patrick Fitzgerald. The whole family who run the Guest House were also very friendly and always keen to help us. Since we had people from South Africa to show us all the amazing sights and their traditional ways to live their lives, the two weeks were very enjoyable for all of us and we came much closer together as a group. You can read this in the following parts of this report. Enjoy! The first group of Apprentices in Oracle (from left to right): Maximilian Michel (DE), Jorge Garnacho (ES), Daniel Maull (UK), Adam Griffiths (UK), Guillermo De Las Nieves (ES), Catriona McGill (UK), Ed Dunlop (UK) The Training Well, it’s time to talk about the main purpose of our trip to South Africa: the training. Two weeks, two courses. Servers and Storage. Two weeks to learn as much as possible and get the certificate. First week: Eben Pretorius with Servers Boot Camp. Learning about: • Machines: T1000, T2000, T3, T4, M series; • How to connect to the machines: serial and network connections; • Levels of software: ALOM, ILOM, OBP and of course the operating system, Solaris Combined with the practical part (screwdriver in one hand, and antistatic wristband on the other) makes quite a lot of stuff! But fortunately, Eben was able to tell us about everything without making our brains explode. For the second week: Storage Boot Camp with Deon Van Vuuren. Taking a look at the content: • Storage machines; • Connectors and protocols: SCSi, SAS, SATA Fiber Channel. Again, huge amounts of information, but Deon definitely did a great job and helped us learn it all. At the end, there was just one question left. Were we able to pass the exam and get the certificate? Well, what can we say? Just take a closer look at the picture above and make your conclusions! Our lovely Oracle office in Woodmead (near Johannesburg) We are all very proud to receive certification in “Server and Storage Support Fundamentals” together with our trainer Deon Van Vuuren. In summary, in case that you don't remember any of the above, the allies for a field engineer are: • System Handbook • EIS-DVD • A proper toolkit With these tools by our side, we’ll be unbeatable!  In the next article later this week, you can find part 2 of our experiences!

  • Ubuntu 12.04 : menu bar started to appear on window

    - by piyush
    I had some broken package problems, and had to reinstall ubuntu-desktop, libqtgui4 and some other system packages. Since then, "some" of my applications are showing menu bar within the window, like this: Some windows like Emacs, vlc are showing such menu bar, while others are working fine (nautilus, terminal still have menu bar on the unity top panel). Is there a way to get it back to the Unity panel?

  • `make install` fails apparently due to typo, but not in makefile: How to find and fix?

    - by Archelon
    I'm trying to install the fujitsu-usb-touchscreen drivers from here, on Kubuntu 12.04 on my new Fujitsu LifeBook P1630. (See fujitsu-usb-touchscreen on kubuntu 13.04 (64-bit) on P1630: `make` errors.) I downloaded the .zip file, unzipped it, and ran make in the directory thus created; this all worked as expected. However, when I run sudo checkinstall (which invokes make install), things go less well. On the first attempt the installation aborted with the following error: make: execvp: /etc/init.d/fujitsu_touchscreen: Permission denied make: *** [install] Error 127 I eventually resolved this by $ sudo chmod +x /etc/init.d/fujitsu_touchscreen But although a second sudo checkinstall then does not give the execvp error, it still fails at a later stage, and the log (on stdout) shows this dpkg error: dpkg: error processing /home/archelon/fujitsu-touchscreen-driver/cybergene-fujitsu-usb-touchscreen-112fdb75b406/cybergene-fujitsu-usb-touchscreen-112fdb75b406_amd64.deb (--install): unable to create `/sys/module/fujitsu/usb/touchscreen/parameters/touch_maxy.dpkg-new' (while processing `/sys/module/fujitsu/usb/touchscreen/parameters/touch_maxy'): No such file or directory And, indeed, there is no /sys/module/fujitsu/usb/touchscreen/parameters/touch_maxy; there is, however, /sys/module/fujitsu_usb_touchscreen/parameters/touch_maxy, and this is presumably what was intended. But this incorrect filename does not appear in the makefile or any other file in the directory, at least not that I can find. Nor does it appear, as I discovered after running sudo checkinstall --install=no as suggested below, in the .deb package created by checkinstall. Where might such a typographical error be originating, and how would I go about fixing it? Edited to add: I'm viewing the contents of the .deb file with ark, Kubuntu's default tool. It contains only three files: control.tar.gz, data.tar.gz, and debian-binary. data.tar.gz contains the directory tree that appears to match up to the usual root filesystem, with /etc, /lib, /sys, and /usr directories. (Looking at other .deb files on my system, this structure appears to be typical.) Here's a screenshot: . (Full size.) Here's another screenshot showing that control.tar.gz contains three files, one of which is empty: . (Full size.) Here's the actual .deb file: https://www.dropbox.com/s/odwxxez0fhyvg7a/cybergene-fujitsu-usb-touchscreen_112fdb75b406-1_amd64.deb Edited 2013-09-28 to add: After reinstalling Kubuntu 12.04 again, this time recreating the /home partition (which, again, had been generated during an install of 13.04), I can no longer reproduce this error. I am still curious to know how the underscores got changed to slashes, but it looks as though nobody has any idea. It is perhaps also of interest to note that while I have still not successfully run checkinstall against this package, I have done make install; it requires the executabilization of /etc/init.d/fujitsu_touchscreen and the installation of hal, and the GUI freezes shortly after installation completes, and there is no particular new functionality afterwards that I have noticed, and the system can no longer resume from being suspended; however, this will be pursued elsewhere.

  • Class instance clustering in object reference graph for multi-entries serialization

    - by Juh_
    My question is on the best way to cluster a graph of class instances (i.e. objects, the graph nodes) linked by object references (the -directed- edges of the graph) around specifically marked objects. To explain better my question, let me explain my motivation: I currently use a moderately complex system to serialize the data used in my projects: "marked" objects have a specific attributes which stores a "saving entry": the path to an associated file on disc (but it could be done for any storage type providing the suitable interface) Those object can then be serialized automatically (eg: obj.save()) The serialization of a marked object 'a' contains implicitly all objects 'b' for which 'a' has a reference to, directly s.t: a.b = b, or indirectly s.t.: a.c.b = b for some object 'c' This is very simple and basically define specific storage entries to specific objects. I have then "container" type objects that: can be serialized similarly (in fact their are or can-be "marked") they don't serialize in their storage entries the "marked" objects (with direct reference): if a and a.b are both marked, a.save() calls b.save() and stores a.b = storage_entry(b) So, if I serialize 'a', it will serialize automatically all objects that can be reached from 'a' through the object reference graph, possibly in multiples entries. That is what I want, and is usually provides the functionalities I need. However, it is very ad-hoc and there are some structural limitations to this approach: the multi-entry saving can only works through direct connections in "container" objects, and there are situations with undefined behavior such as if two "marked" objects 'a'and 'b' both have a reference to an unmarked object 'c'. In this case my system will stores 'c' in both 'a' and 'b' making an implicit copy which not only double the storage size, but also change the object reference graph after re-loading. I am thinking of generalizing the process. Apart for the practical questions on implementation (I am coding in python, and use Pickle to serialize my objects), there is a general question on the way to attach (cluster) unmarked objects to marked ones. So, my questions are: What are the important issues that should be considered? Basically why not just use any graph parsing algorithm with the "attach to last marked node" behavior. Is there any work done on this problem, practical or theoretical, that I should be aware of? Note: I added the tag graph-database because I think the answer might come from that fields, even if the question is not.

  • How do I use GroundControl in 11.10?

    - by Jo-Erlend Schinstad
    When I installed Bazaar Explorer on a fresh system the other day, I came across this Ground Control. I had a look at its web page on http://ground-control.org/ and it looked seriously awesome, so I installed it from Ubuntus repositories. However, I can't find any way of starting it. apt-file shows that it should provide a file named /usr/share/applications/groundcontrol.desktop, but there's no such file. Can someone shed some light on this?

  • What happened to PolicyKit?

    - by Jo-Erlend Schinstad
    Back in 8.04 or so, when PolicyKit was new, we had a GUI "browser" that enabled us to easily decide things like whether a user should be allowed to shutdown the system when other users were logged in and if it should always be allowed or only while on the console, etc. Then those things suddenly disappeared and though it seems PolicyKit is still in use, I haven't been able to find any similar GUI to actually configure the policies. What happened?
