  • Is syncing private keys a good idea?

    - by Jacob Johan Edwards
    Ubuntu One's Security FAQ indicates that Canonical encrypts connections and restricts access to user data. This all well and fine, and I do trust SSL for online banking and other things more valuable than my private keys. That said, I am quite anxious about putting my ~/.ssh/id_dsa up in the cloud. Obviously, no system is totally secure. Could some knowledgeable party, then, pragmatically quantify the risks?

  • Ubuntu Sluggish and Graphics Problem after Nvidia Driver Update

    - by iam
    I just recently started using Ubuntu (12.04) since a few weeks ago and noticed that the interface is very slow and sluggish: On Dash, I have to type the entire app name and wait a few seconds before it shows up in the search box, and a bit later before it displays search result Opening new files or applications takes also quite long and awkward Dragging icons or moving app windows around is not very spontaneous too: I have to take extra attention in moving the mouse otherwise Ubuntu would not do a correct movement or might ends up doing something incorrect instead e.g. opening the windows to full screen options or move the file to different folders, which is frustrating My PC is a few years old already (1.7 GB RAM) so this could be a reason too but when I checked in System Monitor it's hardly ever consuming much memory. Plus web-surfing on Firefox is actually lightning fast (much more than Windows), so I suspect there might be something wrong with the graphics driver (mine is GeForce 7050). I checked around System Settings and found an option to update the Nvidia driver. So I tried it and restarted, as instructed. Now, I got into a big problem upon restart... as the login-screen windows (where I have to type in the password) would take several attempts to display and finally did not manage to (it'd freeze for several seconds before there's any movement again). The background screen also kept reloading several times too and at some point the screen turned black with pixelated color strips running on the bottom 1/3 of the screen, and after a long while the background screen would come up again. Eventually I'd manage to be able to access the desktop but the launcher, top menu bar and app windows border would not disappear. I searched around and found many other people have this similar problem after updating Nvidia driver too, and on some threads the suggestion is to use "killall -u $USER" in command line (it's the only thing among various online suggestions I could do, as at that point I could not access Terminal without the launcher - Ctrl-Alt-T doesn't work for me). So I did that and was able to access the desktop correctly again with launchee/menu by creating a new account. But I would still have the same problem if logging into my original account. So I just finally tried upgrading to 12.10 and now can access my original account with fully-functional desktop - the launcher, menu and windows border are all back now. However, the problem with sluggishness still remains. And now I get scared of ever having to update the Nvidia driver again! I wonder if anyone knows what's the reason that updating the Nvidia driver is causing this problem and is there a way I can update it safely in the future? I'm still not sure how to solve the problem with the sluggishness too and not sure where else to look to find a solution.

  • Sound and Video Skips on Ubuntu 11.10 64 bit

    - by Timothy LaFontaine
    I preformed a dist-upgrade from 11.04 to 11.10 and now I can not listen to any music or sounds (log on sound included), nor watch video without it stopping and then catching up and stopping again (This is flash or .mp4 through VLC). I did not have this issue with 11.04 and have even just preformed a fresh install of my system. I have tried to reinstall Pulse Audio and removing the .pulse folder but to no avail. Any help would be appreciated.

  • Keeping monitor Dell desk monitor 'connected' to dell studio 15 laptop?

    - by Jerry
    First of all, I am new to Ubuntu 10.04 but it is love at first sight and the only windows I will see again are in my house and car! Each time I disconnect my Dell Studio 15 from my Dell 36" monitor, I have to reconnect through the System/Monitor protocol. Question: Is there a way to set it up so once I slide my laptop under the stand, reconnect monitor cable, 3 usb's and press start that the Monitor screen will go 'live' without having to start all over?

  • Virtual Lab part 2&ndash;Templates, Patterns, Baselines

    - by Geoff N. Hiten
    Once you have a good virtualization platform chosen, whether it is a desktop, server or laptop environment, the temptation is to build “X”.  “X” may be a SharePoint lab, a Virtual Cluster, an AD test environment or some other cool project that you really need RIGHT NOW.  That would be doing it wrong. My grandfather taught woodworking and cabinetmaking for twenty-seven years at a trade school in Alabama.  He was the first instructor hired at that school and the only teacher for the first two years.  His students built tables, chairs, and workbenches so the school could start its HVAC courses.   Visiting as a child, I also noticed many extra “helper” stands, benches, holders, and gadgets all built from wood.  What does that have to do with a virtual lab, you ask?  Well, that is the same approach you should take.  Build stuff that you will use.  Not for solving a particular problem, but to let the Virtual Lab be part of your normal troubleshooting toolkit. Start with basic copies of various Operating Systems.  Load and patch server and desktop OS environments.  This also helps build your collection of ISO files, another essential element of a virtual Lab.  Once you have these “baseline” images, you can use your Virtualization software’s snapshot capability to freeze the image.  Clone the snapshot and you have a brand new fully patched machine in mere moments.  You may have to sysprep some of the Microsoft OS environments if you are going to create a domain environment or experiment with clustering.  That is still much faster than loading and patching from scratch. So once you have a stock of raw materials (baseline images in this case) where should you start.  Again, my grandfather’s workshop gives us the answer.  In the shop it was workbenches and tables to hold large workpieces that made the equipment more useful.  In a Windows environment the same role falls to the fundamental network services:  DHCP, DNS, Active Directory, Routing, File Services, and Storage services.  Plan your internal network setup.  Build out an AD controller with all the features listed.  Make the actual domain an isolated domain so it will not care about where you take it.  Add the Microsoft iSCSI target.  Once you have this single system, you can leverage it for almost any network environment beyond a simple stand-alone system. Having these templates and fundamental infrastructure elements ready to run means I can build a quick lab in minutes instead of hours.  My solutions are well-tested, my processes fully documented with screenshots, and my plans validated well before I have to make any changes to client systems.  the work I put in is easily returned in increased value and client satisfaction.

  • Five Key Strategies in Master Data Management

    - by david.butler(at)oracle.com
    Here is a very interesting Profit Magazine article on MDM: A recent customer survey reveals the deleterious effects of data fragmentation. by Trevor Naidoo, December 2010   Across industries and geographies, IT organizations have grown in complexity, whether due to mergers and acquisitions, or decentralized systems supporting functional or departmental requirements. With systems architected over time to support unique, one-off process needs, they are becoming costly to maintain, and the Internet has only further added to the complexity. Data fragmentation has become a key inhibitor in delivering flexible, user-friendly systems. The Oracle Insight team conducted a survey assessing customers' master data management (MDM) capabilities over the past two years to get a sense of where they are in terms of their capabilities. The responses, by 27 respondents from six different industries, reveal five key areas in which customers need to improve their data management in order to get better financial results. 1. Less than 15 percent of organizations surveyed understand the sources and quality of their master data, and have a roadmap to address missing data domains. Examples of the types of master data domains referred to are customer, supplier, product, financial and site. Many organizations have multiple sources of master data with varying degrees of data quality in each source -- customer data stored in the customer relationship management system is inconsistent with customer data stored in the order management system. Imagine not knowing how many places you stored your customer information, and whether a customer's address was the most up to date in each source. In fact, more than 55 percent of the respondents in the survey manage their data quality on an ad-hoc basis. It is important for organizations to document their inventory of data sources and then profile these data sources to ensure that there is a consistent definition of key data entities throughout the organization. Some questions to ask are: How do we define a customer? What is a product? How do we define a site? The goal is to strive for one common repository for master data that acts as a cross reference for all other sources and ensures consistent, high-quality master data throughout the organization. 2. Only 18 percent of respondents have an enterprise data management strategy to ensure that data is treated as an asset to the organization. Most respondents handle data at the department or functional level and do not have an enterprise view of their master data. The sales department may track all their interactions with customers as they move through the sales cycle, the service department is tracking their interactions with the same customers independently, and the finance department also has a different perspective on the same customer. The salesperson may not be aware that the customer she is trying to sell to is experiencing issues with existing products purchased, or that the customer is behind on previous invoices. The lack of a data strategy makes it difficult for business users to turn data into information via reports. Without the key building blocks in place, it is difficult to create key linkages between customer, product, site, supplier and financial data. These linkages make it possible to understand patterns. A well-defined data management strategy is aligned to the business strategy and helps create the governance needed to ensure that data stewardship is in place and data integrity is intact. 3. Almost 60 percent of respondents have no strategy to integrate data across operational applications. Many respondents have several disparate sources of data with no strategy to keep them in sync with each other. Even though there is no clear strategy to integrate the data (see #2 above), the data needs to be synced and cross-referenced to keep the business processes running. About 55 percent of respondents said they perform this integration on an ad hoc basis, and in many cases, it is done manually with the help of Microsoft Excel spreadsheets. For example, a salesperson needs a report on global sales for a specific product, but the product has different product numbers in different countries. Typically, an analyst will pull all the data into Excel, manually create a cross reference for that product, and then aggregate the sales. The exact same procedure has to be followed if the same report is needed the following month. A well-defined consolidation strategy will ensure that a central cross-reference is maintained with updates in any one application being propagated to all the other systems, so that data is synchronized and up to date. This can be done in real time or in batch mode using integration technology. 4. Approximately 50 percent of respondents spend manual efforts cleansing and normalizing data. Information stored in various systems usually follows different standards and formats, making it difficult to match the data. A customer's address can be stored in different ways using a variety of abbreviations -- for example, "av" or "ave" for avenue. Similarly, a product's attributes can be stored in a number of different ways; for example, a size attribute can be stored in inches and can also be entered as "'' ". These types of variations make it difficult to match up data from different sources. Today, most customers rely on manual, heroic efforts to match, cleanse, and de-duplicate data -- clearly not a scalable, sustainable model. To solve this challenge, organizations need the ability to standardize data for customers, products, sites, suppliers and financial accounts; however, less than 10 percent of respondents have technology in place to automatically resolve duplicates. It is no wonder, therefore, that we get communications about products we don't own, at addresses we don't reside, and using channels (like direct mail) we don't like. An all-too-common example of a potential challenge follows: Customers end up receiving duplicate communications, which not only impacts customer satisfaction, but also incurs additional mailing costs. Cleansing, normalizing, and standardizing data will help address most of these issues. 5. Only 10 percent of respondents have the ability to share data that was mastered in a master data hub. Close to 60 percent of respondents have efforts in place that profile, standardize and cleanse data manually, and the output of these efforts are stored in spreadsheets in various parts of the organization. This valuable information is not easily shared with the rest of the organization and, more importantly, this enriched information cannot be sent back to the source systems so that the data is fixed at the source. A key benefit of a master data management strategy is not only to clean the data, but to also share the data back to the source systems as well as other systems that need the information. Aside from the source systems, another key beneficiary of this data is the business intelligence system. Having clean master data as input to business intelligence systems provides more accurate and enhanced reporting.  Characteristics of Stellar MDM When deciding on the right master data management technology, organizations should look for solutions that have four main characteristics: enterprise-grade MDM performance complete technology that can be rapidly deployed and addresses multiple business issues end-to-end MDM process management with data quality monitoring and assurance pre-built MDM business relevant applications with data stores and workflows These master data management capabilities will aid in moving closer to a best-practice maturity level, delivering tremendous efficiencies and savings as well as revenue growth opportunities as a result of better understanding your customers.  Trevor Naidoo is a senior director in Industry Strategy and Insight at Oracle.

  • Proxy setttings not working in Ubuntu 11.10

    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.

  • How to set the monitor to its native resolution when xrandr approach isn't working?

    - by Krishna Kant Sharma
    I am trying to setup my Samsung syncmaster B2030 monitor in ubuntu 12.04. It's native resolution is 1600x900 which I am not getting in ubuntu and which I am trying to get. I tried using xrandr approach provided in these urls: 1) http://www.ubuntugeek.com/how-change-display-resolution-settings-using-xrandr.html 2) How to set the monitor to its native resolution which is not listed in the resolutions list? S1) I used cvt 1600 900 60 to get the modeline. Output was: # 1600x900 59.95 Hz (CVT 1.44M9) hsync: 55.99 kHz; pclk: 118.25 MHz Modeline "1600x900_60.00" 118.25 1600 1696 1856 2112 900 903 908 934 -hsync +vsync S2) I then used xrandr and output was: Screen 0: minimum 8 x 8, current 1152 x 864, maximum 8192 x 8192 DVI-I-0 disconnected (normal left inverted right x axis y axis) VGA-0 connected 1152x864+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1024x768 60.0 + 1360x768 60.0 59.8 1152x864 60.0* 800x600 72.2 60.3 56.2 680x384 119.9 119.6 640x480 59.9 512x384 120.0 400x300 144.4 320x240 120.1 DVI-I-1 disconnected (normal left inverted right x axis y axis) HDMI-0 disconnected (normal left inverted right x axis y axis) which gave me "VGA-0". S3) Then I used xrandr --newmode "1600x900_60.00" 118.25 1600 1696 1856 2112 900 903 908 934 -hsync +vsync But instead of adding the modeline it just threw an error: X Error of failed request: BadName (named color or font does not exist) Major opcode of failed request: 153 (RANDR) Minor opcode of failed request: 16 (RRCreateMode) Serial number of failed request: 29 Current serial number in output stream: 29 My system details: 1) ubuntu 12.04 LTS 2) Graphic card: GeForce 9400 GT/PCIe/SSE2 (driver is successfully installed. I am checking it in System Settings Details. And it's showing that driver is installed and its "GeForce 9400 GT/PCIe/SSE2") 3) Monitor: Samsung syncmaster B2030 4) Resolutions I am getting: 800x600 1024x768 1152x864 (I am currently using this one) 1360x768 (this one isn't working properly) Does anyone know what I can do? Thanks in advance. UPDATE (1): Today I tried it again. And adding a modeline (using --newmode) worked. But when I used --addmode by: xrandr --addmode VGA-0 1600x900_60.00 It gave this error: X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 153 (RANDR) Minor opcode of failed request: 18 (RRAddOutputMode) Serial number of failed request: 29 Current serial number in output stream: 30

  • *Un*installing with Ubuntu Software Center (Centre) doesn't work on 64-bit 12.04.1

    - by likethesky
    Not sure if I'm doing something wrong, or if the .deb package I'm installing is broken in some way (I've built it, using NetBeans 7.2), or if indeed this is a bug in Software Center. When I install this particular 32-bit .deb on Ubuntu 10.04 LTS--all updates applied--(where it was built), GDebi shows it and has an 'Uninstall' button next to it. So it works fine to uninstall it there, via the GDebi GUI. However, when I install it on 12.04.1 LTS--all updates applied--it installs fine, but then does not show up in Ubuntu Software Center as available to be uninstalled. No combination of searching finds it. However, I can from the command line, do sudo apt-get purge javafxapplication1 and it finds it and deletes it. The same thing happens when I build a 64-bit .deb and attempt to install it to the same (64-bit AMD) or a different 64-bit Ubuntu 12.04.1 system. So it seems to be isolated to this NetBeans-generated .deb and the 64-bit AMD build (though I haven't tried it on a 32-bit 12.04.1 install yet). These are all on VirtualBox VMs, btw, if that matters. Any way to 'clean up' my Software Center and see if it's something I've done to get it in this state? Could this behavior be due to how this particular .deb has been built? (It doesn't have an 'Installed-Size' control field, so I do get the "Package is of bad quality" warning when I install it--which I do by clicking 'Ignore and install' button.) If you want all the gory details about why this happening--a bug has been reported against NetBeans for this behavior here: http://javafx-jira.kenai.com/browse/RT-25486 (EDIT: Just to be clear, the app installs fine, runs fine, all works as intended--I just can't get that 'bad package' message to go away, and now... I also can't uninstall it via Software Center, but rather, need to use sudo apt-get purge to uninstall it, after it installs. /END EDIT) Thanks for any pointers. I'm happy to report this as a bug against Ubuntu Software Center/Centre too, if that's what it seems to be, just tell me where to do so (a link). I'm a relative Ubuntu, NetBeans, and JavaFX newbie, though a long-time programmer. If I report it as a bug, I'll try it on the 32-bit build of 12.04.1 as well. Also, if I should add any more detail to the bug reported against NetBeans above, let me know--or feel free to add it yourself to the bug report above, if you would like. Thanks again!

  • 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.

  • After last update Unity no longer works

    - by Alen
    An hour ago I installed latest updates and now Unity doesn't work anyomore, I only see desktop with icons. Manually searching I opened system monitor and found out only 400 Mb of RAM is taken which means complete Unity is turned off. Can someone help me to fix this. Since I'm crippled I probably won't be able to provide you with all details you need because I don't have window borders, no right click menu, nothing, only Nautilus.

Do you have any suggestions for robust, flexible affiliate software? Thanks.
