  • apt-get update bzip2 errors

    - by Tejas Kale
    I installed Ubuntu 11.10 today on my Lenovo w500. After that when i tried running sudo apt-get update This is the error i am getting. Get:117 http://ftp.jaist.ac.jp oneiric-security/universe TranslationIndex [73 B] 99% [48 Sources bzip2 0 B] [22 Sources bzip2 5,294 kB] 1,983 kB/s 0s bzip2: Compressed file ends unexpectedly; perhaps it is corrupted? *Possible* reason follows. bzip2: Inappropriate ioctl for device Input file = (stdin), output file = (stdout) It is possible that the compressed file(s) have become corrupted. You can use the -tvv option to test integrity of such files. You can use the `bzip2recover' program to attempt to recover data from undamaged sections of corrupted files. I found the following similar question : Errors while updating Ubuntu 11.10 , But the solutions mentioned ( changing the download server, running apt-get clean, apt-get autoclean) and have also tried removing the /var/cache/apt/archives/lists direcotry. As a result of this, I am unable to install any new packages.

  • Azure Diagnostics: The Bad, The Ugly, and a Better Way

    - by jasont
    If you’re a .Net web developer today, no doubt you’ve enjoyed watching Windows Azure grow up over the past couple of years. The platform has scaled, stabilized (mostly), and added on a slew of great (and sometimes overdue) features. What was once just an endpoint to host a solution, developers today have tremendous flexibility and options in the platform. Organizations are building new solutions and offerings on the platform, and others have, or are in the process of, migrating existing applications out of their own data centers into the Azure cloud. Whether new application development or migrating legacy, every development shop and IT organization needs to monitor their applications in the cloud, the same as they do on premises. Azure Diagnostics has some capabilities, but what I constantly hear from users is that it’s either (a) not enough, or (b) too cumbersome to set up. Today, Stackify is happy to announce that we fully support Azure deployments, just the same as your on-premises deployments. Let’s take a look below and compare and contrast the options. Azure Diagnostics Let’s crack open the Windows Azure documentation on Azure Diagnostics and see just how easy it is to use. The high level steps are:   Step 1: Import the Diagnostics Oh, I’ve already deployed my app without the diagnostics module. Guess I can’t do anything until I do this and re-deploy. Step 2: Configure the Diagnostics (and multiple sub-steps) Do I want it all? Or just pieces of it? Whoops, forgot to include a specific performance counter, I guess I’ll have to deploy again. Wait a minute… I have to specifically code these performance counters into my role’s OnStart() method, compile and deploy again? And query and consume it myself? Step 3: (Optional) Permanently store diagnostic data Lucky for me, Azure storage has gotten pretty cheap. But how often should I move the data into storage? I want to see real-time data, so I guess that’s out now as well. Step 4: (Optional) View stored diagnostic data Optional? Of course I want to see it. Conveniently, Microsoft recommends 3 tools to do this with. Un-conveniently, none of these are web based and they all just give you access to raw data, and very little charting or real-time intelligence. Just….. data. Nevermind that one product seems to have gotten stale since a recent acquisition, and doesn’t even have screenshots!   So, let’s summarize: lots of diagnostics data is available, but think realistically. Think Dev Ops. What happens when you are in the middle of a major production performance issue and you don’t have the diagnostics you need? You are redeploying an application (and thankfully you have a great branching strategy, so you feel perfectly safe just willy-nilly launching code into prod, don’t you?) to get data, then shipping it to storage, and then digging through that data to find a needle in a haystack. Would you like to be able to troubleshoot a performance issue in the middle of the night, or on a weekend, from your iPad or home computer’s web browser? Forget it: the best you get is this spark line in the Azure portal. If it’s real pointy, you probably have an issue; but since there is no alert based on a threshold your customers have likely already let you know. And high CPU, Memory, I/O, or Network doesn’t tell you anything about where the problem is. The Better Way – Stackify Stackify supports application and server monitoring in real time, all through a great web interface. All of the things that Azure Diagnostics provides, Stackify provides for your on-premises deployments, and you don’t need to know ahead of time that you’ll need it. It’s always there, it’s always on. Azure deployments are essentially no different than on-premises. It’s a Windows Server (or Linux) in the cloud. It’s behind a different firewall than your corporate servers. That’s it. Stackify can provide the same powerful tools to your Azure deployments in two simple steps. Step 1 Add a startup task to your web or worker role and deploy. If you can’t deploy and need it right now, no worries! Remote Desktop to the Azure instance and you can execute a Powershell script to download / install Stackify.   Step 2 Log in to your account at www.stackify.com and begin monitoring as much as you want, as often as you want and see the results instantly. WMI? It’s there Event Viewer? You’ve got it. File System Access? Yes, please! Would love to make sure my web.config is correct.   IIS / App Pool Info? Yep. You can even restart it. Running Services? All of them. Start and Stop them to your heart’s content. SQL Database access? You bet’cha. Alerts and Notification? Of course! You should know before your customers let you know. … and so much more.   Conclusion Microsoft has shown, consistently, that they love developers, developers, developers. What every developer needs to realize from this is that they’ve given you a canvas, which is exactly what Azure is. It’s great infrastructure that is readily available, easy to manage, and fairly cost effective. However, the tooling is your responsibility. What you get, at best, is bare bones. App and server diagnostics should be available when you need them. While we, as developers, try to plan for and think of everything ahead of time, there will come times where we need to get data that just isn’t available. And having to go through a lot of cumbersome steps to get that data, and then have to find a friendlier way to consume it…. well, that just doesn’t make a lot of sense to me. I’d rather spend my time writing and developing features and completing bug fixes for my applications, than to be writing code to monitor and diagnose.

  • Is it important for reflection-based serialization maintain consistent field ordering?

    - by Matchlighter
    I just finished writing a packet builder that dynamically loads data into a data stream for eventual network transmission. Each builder operates by finding fields in a given class (and its superclasses) that are marked with a @data annotation. When I finishing my implementation, I remembered that getFields() does not return results in any specific order. Should reflection-based methods for serializing arbitrary data (like my packets) attempt to preserve a specific field ordering (such as alphabetical), and if so, how?

  • Why can't I refresh the list of packages?

    - by Elysium
    This might be a duplicate, but I can't find a solution in other posts. Whenever I try to update I get this message: ERROR###ERROR###ERROR###ERROR###ERROR###ERROR###ERROR E:Encountered a section with no Package: header, E:Problem with MergeList /var/lib/apt/listspackages.medibuntu.org_dists_quantal_free_i18n_Translation-en, E:The package lists or status file could not be parsed or opened. I have tried runnig this in the terminal: sudo rm /var/lib/apt/lists/* -vf sudo apt-get update It doesn't work at all. I cant even open the software sources and "sudo apt-get check" gives me this message: Reading package lists... Error! E: Encountered a section with no Package: header E: Problem with MergeList /var/lib/apt/lists/packages.medibuntu.org_dists_quantal_free_i18n_Translation-en E: The package lists or status file could not be parsed or opened. UPDATE: solution for me was to remove the medibuntu-keyring through synaptic manager and removed mediubuntu from the software sources too manually. This seems to have solved the problem. The update manager doesnt give me any error messages anymore.

  • 32 bit ODBC drivers on 64 bit Windows

    It’s been a while since I had to use an ODBC driver.  Today I learned… That when you install a 32 bit ODBC driver on a 64 bit Windows but it doesn’t show up in the Data Sources admin tool because this tool displays only 64 bit drivers. That you can manage a 32 bit ODBC driver on a 64 bit Windows using the 32 bit Data Sources admin tool located here: C:\Windows\SysWOW64\odbcad32.exe That 64 bit software can’t use 32 bit ODBC drivers.

  • The need for user-defined index types

    - by Greg Low
    Since the removal of the 8KB limit on serialization, the ability to define new data types using SQL CLR integration is now almost at a usable level, apart from one key omission: indexes. We have no ability to create our own types of index to support our data types. As a good example of this, consider that when Microsoft introduced the geometry and geography (spatial) data types, they did so as system CLR data types but also needed to introduce a spatial index as a new type of index. Those of us that...(read more)

    - by Luuz
    I'm using ubuntu 11.10 and in the update manager I have a message that says package information last updated 59 days ago press the check button to check for software updates I do that, but i'm up to date. I checked other threads with this same problem, and saw i should do sudo apt-get update in a terminal to see which repository is not up to date and when I did, I got this message: Failed to fetch http://extras.ubuntu.com/ubuntu/dists/oneiric/Release Then I checked for this repository in software sources but couldn't find this specific one. In my /etc/apt/sources.list.d I have only one line: deb http://archive.canonical.com/ubuntu oneiric partner #Added by software-center So now I don't know what to do more. Should I upgrade to 12.04 and will it solve my problem? I wouldn't want to upgrade if there is a problem in the last version but I don't know much about Ubuntu so, can anyone help me please? Thank you!!

  • Adding Bzr Launchpad PPA to Ubuntu Hardy

    - by Robery Stackhouse
    I've got TortoiseBazaar installed on my Windows laptop, and I was trying to branch a repository hosted on my VPS to another directory on my VPS, and I got this lovely error: bzr: ERROR: Unknown branch format: 'Bazaar Branch Format 7 (needs bzr 1.6) That lead me to this mailing-list archive: http://osdir.com/ml/bazaar/2009-06/msg00692.html Then I tried following the instructions here to add the Launchpad PPA to /etc/apt/sources.list, but they forgot to mention that you need to do this: sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com D702BF6B8C6C1EFD Which I found out about here after I got this error: GPG error: http://ppa.launchpad.net hardy Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY D702BF6B8C6C1EFD after modifying my /etc/apt/sources.list and running: sudo apt-get update Just thought I'd save someone else some pain. And of course, don't forget to uninstall the version of bzr that wouldn't play ball in the first place.

  • Oracle WebCenter: Composite Applications & Mash-Ups

    - by kellsey.ruppel(at)oracle.com
    We’ve talked in previous weeks about the key goals of the new release of WebCenter are providing a Modern User Experience, unparalleled Application Integration, converging all the best of the existing portal platforms into WebCenter and delivering a Common User Experience Architecture.  We’ve provided an overview of Oracle WebCenter and discussed some of the other key goals in previous weeks, and this week, we’ll focus on how with the new release of Oracle WebCenter you can create composite applications and mashups.We recently talked with Sachin Agarwal, Director of Product Management of Enterprise 2.0 at Oracle around the topic of Composite Applications and Mashups. Oracle WebCenter provides a rich set of tools and capabilities for pulling in content, applications and collaboration functionality from various different sources and weaving them together into what we call Mashups. Mashups that also consists of transactional applications from multiple sources are specifically called Composite Applications. With the latest release of Oracle WebCenter one can develop highly productive tasked based interfaces that aggregate a related set of applications that are part of a business process and provide in context collaboration tools so that users don’t have to navigate away to different tabs to achieve these tasks. For instance, a call center representative (CSR), not only needs to be able to pull customer information from a CRM application like Siebel, but also related information from Oracle E-Business Suite about whether a specific order has shipped. The CSR will be far more efficient if he or she does not have to open different tabs to login into multiple applications while the customer is waiting, but can access all this information in one mashup.Oracle WebCenter Suite provides a comprehensive set of tooling that enables a business user to quickly aggregate together a mashup and wire-in different backend applications to create a custom dashboard. Not only does Oracle WebCenter supports a wide set of standards (WSRP 1.0, 2.0, JSR 168, JSR 286) that allow portlets  from other applications to be surfaced within WebCenter, but it also provides tools to bring in other web applications such as .Net Applications  as well as SharePoint webparts. The new Business Mash-up editor allows business users to take any Oracle Application or 3rd party application and wire the backend data sources or APIs to a rich set of visualizations and reuse them in mashups.  Moreover, Business users can customize or personalize any page using Oracle WebCenter Composer’s on-the-fly visual page editing features. Users access and select different resource components available in Oracle WebCenter’s Business Dictionary in order to add new content to the page. The Business Dictionary provides a role-based view of available components or resources, and these components can include information from a variety of enterprise resources such as enterprise applications, managed content, rich media, business processes, or business intelligence systems. Together, Oracle WebCenter’s Composer and Business Dictionary give users access to a powerful, yet easy to use, set of tools to personalize and extend their Oracle WebCenter portals and applications without involving IT.Keep checking back this week as we share more information on how you can easily create Commposite Applications and Mashups with Oracle WebCenter .Technorati Tags: UXP, collaboration, enterprise 2.0, modern user experience, oracle, portals, webcenter, applications, mashups, composite applications

  • Avoid GPL violation by moving library out of process

    Assume there is a library that is licensed under GPL. I want to use it is closed source project. I do following: Create small wrapper application around that GPL library that listens to socket, parse messages and call GPL library. Then returns results back. Release it's sources (to comply with GPL) Create client for this wrapper in my main application and don't release sources. I know that this adds huge overhead compared to static/dynamic linking, but I am interested in theoretical way.

  • Isn't MVC anti OOP?

    - by m3th0dman
    The main idea behind OOP is to unify data and behavior in a single entity - the object. In procedural programming there is data and separately algorithms modifying the data. In the Model-View-Controller pattern the data and the logic/algorithms are placed in distinct entities, the model and the controller respectively. In an equivalent OOP approach shouldn't the model and the controller be placed in the same logical entity?

  • logrotate isn't rotating a particular log file (and i think it should be)

    - by Max Williams
    Hi all. For a particular app, i have log files in two places. One of the places has just one log file that i want to use with logrotate, for the other location i want to use logrotate on all log files in that folder. I've set up an entry called millionaire-staging in /etc/logrotate.d and have been testing it by calling logrotate -f millionaire-staging. Here's my entry: #/etc/logrotate.d/millionaire-staging compress rotate 1000 dateext missingok sharedscripts copytruncate /var/www/apps/test.millionaire/log/staging.log { weekly } /var/www/apps/test.millionaire/shared/log/*log { size 40M } So, for the first folder, i want to rotate weekly (this seems to have worked fine). For the other, i want to rotate only when the log files get bigger than 40 meg. When i look in that folder (using the same locator as in the logrotate config), i can see a file in there that's 54M and which hasn't been rotated: $ ls -lh /var/www/apps/test.millionaire/shared/log/*log -rw-r--r-- 1 www-data root 33M 2010-12-29 15:00 /var/www/apps/test.millionaire/shared/log/test.millionaire.charanga.com.access-log -rw-r--r-- 1 www-data root 54M 2010-09-10 16:57 /var/www/apps/test.millionaire/shared/log/test.millionaire.charanga.com.debug-log -rw-r--r-- 1 www-data root 53K 2010-12-14 15:48 /var/www/apps/test.millionaire/shared/log/test.millionaire.charanga.com.error-log -rw-r--r-- 1 www-data root 3.8M 2010-12-29 14:30 /var/www/apps/test.millionaire/shared/log/test.millionaire.charanga.com.ssl.access-log -rw-r--r-- 1 www-data root 16K 2010-12-17 15:00 /var/www/apps/test.millionaire/shared/log/test.millionaire.charanga.com.ssl.error-log -rw-r--r-- 1 deploy deploy 0 2010-12-29 14:49 /var/www/apps/test.millionaire/shared/log/unicorn.stderr.log -rw-r--r-- 1 deploy deploy 0 2010-12-29 14:49 /var/www/apps/test.millionaire/shared/log/unicorn.stdout.log Some of the other log files in that folder have been rotated though: $ ls -lh /var/www/apps/test.millionaire/shared/log total 91M -rw-r--r-- 1 www-data root 33M 2010-12-29 15:05 test.millionaire.charanga.com.access-log -rw-r--r-- 1 www-data root 54M 2010-09-10 16:57 test.millionaire.charanga.com.debug-log -rw-r--r-- 1 www-data root 53K 2010-12-14 15:48 test.millionaire.charanga.com.error-log -rw-r--r-- 1 www-data root 3.8M 2010-12-29 14:30 test.millionaire.charanga.com.ssl.access-log -rw-r--r-- 1 www-data root 16K 2010-12-17 15:00 test.millionaire.charanga.com.ssl.error-log -rw-r--r-- 1 deploy deploy 0 2010-12-29 14:49 unicorn.stderr.log -rw-r--r-- 1 deploy deploy 41K 2010-12-29 11:03 unicorn.stderr.log-20101229.gz -rw-r--r-- 1 deploy deploy 0 2010-12-29 14:49 unicorn.stdout.log -rw-r--r-- 1 deploy deploy 1.1K 2010-10-15 11:05 unicorn.stdout.log-20101229.gz I think what might have happened is that i first ran this config with a pattern matching *.log, and that means it only rotated the two files that ended in .log (as opposed to -log). Then, when i changed the config and ran it again, it won't do any more since it think's its already had its weekly run, or something. Can anyone see what i'm doing wrong? Is it to do with those top folders being owned by root rather than deploy do you think? thanks, max

  • Unit testing - getting started

    - by higgenkreuz
    I am just getting started with unit testing but I am not sure if I really understand the point of it all. I read tutorials and books on it all, but I just have two quick questions: I thought the purpose of unit testing is to test code we actually wrote. However, to me it seems that in order to just be able to run the test, we have to alter the original code, at which point we are not really testing the code we wrote but rather the code we wrote for testing. Most of our codes rely on external sources. Upon refactoring our code however, even it would break the original code, our tests still would run just fine, since the external sources are just muck-ups inside our test cases. Doesn't it defeat the purpose of unit testing? Sorry if I sound dumb here, but I thought someone could enlighten me a bit. Thanks in advance.

Here's my entry: #/etc/logrotate.d/millionaire-staging compress rotate 1000 dateext missingok sharedscripts copytruncate /var/www/apps/test.millionaire/log/staging.log { weekly } /var/www/apps/test.millionaire/shared/log/*log { size 40M } So, for the first folder, i want to rotate weekly (this seems to have worked fine). For the other, i want to rotate only when the log files get bigger than 40 meg. When i look in that folder (using the same locator as in the logrotate config), i can see a file in there that's 54M and which hasn't been rotated: $ ls -lh /var/www/apps/test.millionaire/shared/log/*log -rw-r--r-- 1 www-data root 33M 2010-12-29 15:00 /var/www/apps/test.millionaire/shared/log/test.millionaire.charanga.com.access-log -rw-r--r-- 1 www-data root 54M 2010-09-10 16:57 /var/www/apps/test.millionaire/shared/log/test.millionaire.charanga.com.debug-log -rw-r--r-- 1 www-data root 53K 2010-12-14 15:48 /var/www/apps/test.millionaire/shared/log/test.millionaire.charanga.com.error-log -rw-r--r-- 1 www-data root 3.8M 2010-12-29 14:30 /var/www/apps/test.millionaire/shared/log/test.millionaire.charanga.com.ssl.access-log -rw-r--r-- 1 www-data root 16K 2010-12-17 15:00 /var/www/apps/test.millionaire/shared/log/test.millionaire.charanga.com.ssl.error-log -rw-r--r-- 1 deploy deploy 0 2010-12-29 14:49 /var/www/apps/test.millionaire/shared/log/unicorn.stderr.log -rw-r--r-- 1 deploy deploy 0 2010-12-29 14:49 /var/www/apps/test.millionaire/shared/log/unicorn.stdout.log Some of the other log files in that folder have been rotated though: $ ls -lh /var/www/apps/test.millionaire/shared/log total 91M -rw-r--r-- 1 www-data root 33M 2010-12-29 15:05 test.millionaire.charanga.com.access-log -rw-r--r-- 1 www-data root 54M 2010-09-10 16:57 test.millionaire.charanga.com.debug-log -rw-r--r-- 1 www-data root 53K 2010-12-14 15:48 test.millionaire.charanga.com.error-log -rw-r--r-- 1 www-data root 3.8M 2010-12-29 14:30 test.millionaire.charanga.com.ssl.access-log -rw-r--r-- 1 www-data root 16K 2010-12-17 15:00 test.millionaire.charanga.com.ssl.error-log -rw-r--r-- 1 deploy deploy 0 2010-12-29 14:49 unicorn.stderr.log -rw-r--r-- 1 deploy deploy 41K 2010-12-29 11:03 unicorn.stderr.log-20101229.gz -rw-r--r-- 1 deploy deploy 0 2010-12-29 14:49 unicorn.stdout.log -rw-r--r-- 1 deploy deploy 1.1K 2010-10-15 11:05 unicorn.stdout.log-20101229.gz I think what might have happened is that i first ran this config with a pattern matching *.log, and that means it only rotated the two files that ended in .log (as opposed to -log). Then, when i changed the config and ran it again, it won't do any more since it think's its already had its weekly run, or something. Can anyone see what i'm doing wrong? Is it to do with those top folders being owned by root rather than deploy do you think? thanks, max

  • Building an MVC application using QuickBooks

    - by dataintegration
    RSSBus ADO.NET Providers can be used from many tools and IDEs. In this article we show how to connect to QuickBooks from an MVC3 project using the RSSBus ADO.NET Provider for QuickBooks. Although this example uses the QuickBooks Data Provider, the same process can be used with any of our ADO.NET Providers. Creating the Model Step 1: Download and install the QuickBooks Data Provider from RSSBus. Step 2: Create a new MVC3 project in Visual Studio. Add a data model to the Models folder using the ADO.NET Entity Data Model wizard. Step 3: Create a new RSSBus QuickBooks Data Source by clicking "New Connection", specify the connection string options, and click Next. Step 4: Select all the tables and views you need, and click Finish to create the data model. Step 5: Right click on the entity diagram and select 'Add Code Generation Item'. Choose the 'ADO.NET DbContext Generator'. Creating the Controller and the Views Step 6: Add a new controller to the Controllers folder. Give it a meaningful name, such as ReceivePaymentsController. Also, make sure the template selected is 'Controller with empty read/write actions'. Before adding new methods to the Controller, create views for your model. We will add the List, Create, and Delete views. Step 7: Right click on the Views folder and go to Add -> View. Here create a new view for each: List, Create, and Delete templates. Make sure to also associate your Model with the new views. Step 10: Now that the views are ready, go back and edit the RecievePayment controller. Update your code to handle the Index, Create, and Delete methods. Sample Project We are including a sample project that shows how to use the QuickBooks Data Provider in an MVC3 application. You may download the C# project here or download the VB.NET project here. You will also need to install the QuickBooks ADO.NET Data Provider to run the demo. You can download a free trial here. To use this demo, you will also need to modify the connection string in the 'web.config'.
