  • Monit fails to start/stop HTTPD

    - by mYzk
    I have done a monit HTTPD check. The problem is that once monit is run it will stop HTTPD but HTTPD workers will still be running. I have tried to change stop command /etc/init.d/httpd stop to /usr/sbin/httpd -k stop, but it does stop the HTTPD but workers will still be running. Once I kill HTTPD workers via kill command (ps aux) then I can start the HTTPD again. Has anyone seens something like this?

  • Why Does Ejabberd Start Fail?

    - by Andrew
    I am trying to install ejabberd 2.1.10-2 on my Ubuntu 12.04.1 server. This is a fresh install, and ejabberd is never successfully installed. The Install Every time, apt-get hangs on this: Setting up ejabberd (2.1.10-2ubuntu1) ... Generating SSL certificate /etc/ejabberd/ejabberd.pem... Creating config file /etc/ejabberd/ejabberd.cfg with new version Starting jabber server: ejabberd............................................................ failed. The dots just go forever until it times out or I 'killall' beam, beam.smp, epmd, and ejabberd processes. I've turned off all firewall restrictions. Here's the output of epmd -names while the install is hung: epmd: up and running on port 4369 with data: name ejabberdctl at port 42108 name ejabberd at port 39621 And after it fails: epmd: up and running on port 4369 with data: name ejabberd at port 39621 At the same time (during and after), the output of both netstat -atnp | grep 5222 and netstat -atnp | grep 5280 is empty. The Crash File A crash dump file is create at /var/log/ejabber/erl_crash.dump. The slogan (i.e. reason for the crash) is: Slogan: Kernel pid terminated (application_controller) ({application_start_failure,kernel,{shutdown,{kernel,start,[normal,[]]}}}) It's alive? Whenever I try to relaunch ejabberd with service ejabberd start, the same thing happens - even if I've killed all processes before doing so. However, when I killall the processes listed above again, and run su - ejabberd -c /usr/sbin/ejabberd, this is the output I get: Erlang R14B04 (erts-5.8.5) [source] [64-bit] [rq:1] [async-threads:0] [kernel-poll:false] Eshell V5.8.5 (abort with ^G) (ejabberd@ns1)1> =INFO REPORT==== 15-Oct-2012::12:26:13 === I(<0.478.0>:ejabberd_listener:166) : Reusing listening port for 5222 =INFO REPORT==== 15-Oct-2012::12:26:13 === I(<0.479.0>:ejabberd_listener:166) : Reusing listening port for 5269 =INFO REPORT==== 15-Oct-2012::12:26:13 === I(<0.480.0>:ejabberd_listener:166) : Reusing listening port for 5280 =INFO REPORT==== 15-Oct-2012::12:26:13 === I(<0.40.0>:ejabberd_app:72) : ejabberd 2.1.10 is started in the node ejabberd@ns1 Then, the server appears to be running. I get a login prompt when I access http://mydomain.com:5280/admin/. Of course I can't login unless I create an account. At this time, the output of netstat -atnp | grep 5222 and netstat -atnp | grep 5280 is as follows: tcp 0 0 0.0.0.0:5222 0.0.0.0:* LISTEN 19347/beam tcp 0 0 0.0.0.0:5280 0.0.0.0:* LISTEN 19347/beam ejabberdctl Even when it appears ejabberd is running, trying to do anything with ejabberdctl fails. For example: trying to register a user: root@ns1:~# ejabberdctl register myusername mydomain.com mypassword Failed RPC connection to the node ejabberd@ns1: nodedown I have no idea what I'm doing wrong. This happens on two different servers I have with identical software installed (really not much of anything). Please help. Thanks.

  • XChat window start with bottom edge covered

    - by jasmines
    When I start Xchat, I note the issue: As you can see, the bottom edge of the window is covered by some other thing (in this case, it's firefox status bar, but if I have no other window opened, I see my desktop background in that position), so I reduce it with the maximize button on top left: Finally I maximize it again and obtain the wanted behaviour: Is this a bug or can I adjust it in any way?

  • Does Ubuntu run on current Asus Transformer Prime?

    - by Ubuntu User
    I've read instructions about dual boot Android / Transformer Prime (a significant factor in ordering one). Also about not working with /latest/ Transformer Prime (firmware / BIOS?) Also about imminent Ubuntu ARM support. Will I be able to run Ubuntu in a day or two when Transformer arrives? Also, am I right to assume I can restore Transformer to factory status if I break something in the attempt?

  • Learnings from trying to write better software: Loud errors from the very start

    - by theo.spears
    Microsoft made a very small number of backwards incompatible changes between .NET 1.1 and 2.0, because they wanted to make it as easy and safe as possible to port applications to the new runtime. (Here’s a list.) However, one thing they did change was what happens when a background thread fails with an unhanded exception - in .NET 1.1 nothing happened, the thread terminated, and the application continued oblivious. Try the same trick in .NET 2.0 and the entire application, including all threads, will rudely terminate. There are three reasons for this. Firstly if a background thread has crashed, it may have left the entire application in an inconsistent state, in a way that will affect other threads. It’s better to terminate the entire application than continue and have the application perform actions based on a broken state, for example take customer orders, or write corrupt files to disk.  Secondly, during software development, it is far better for errors to be loud and obtrusive. Even if you have unit tests and integration tests (and you should), a key part of ensuring software works properly is to actually try using it, both through systematic testing and through the casual use all software gets by its developers during use. Subtle errors are easy to miss if you are not actually doing real work using the application, loud errors are obvious. Thirdly, and most importantly, even if catching and swallowing exceptions indiscriminately doesn't cause any problems in your application, the presence of unexpected exceptions shows you do not fully understand the behavior of your code. The currently released version of your application may be absolutely correct. However, because your mental model of the behavior is wrong, any future change you make to the program could and probably will introduce critical errors.  This applies to more than just exceptions causing threads to exit, any unexpected state should make the application blow up in an un-ignorable way. The worst thing you can do is silently swallow errors and continue. And let's be clear, writing to a log file does not count as blowing up in an un-ignorable way.  This is all simple as long as the call stack only contains your code, but when your functions start to be called by third party or .NET framework code, it's surprisingly easy for exceptions to start vanishing. Let's look at two examples.   1. Windows forms drag drop events  Usually if you throw an exception from a winforms event handler it will bring up the "application has crashed" dialog with abort and continue options. This is a good default behavior - the error is big and loud, but it is possible for the user to ignore the error and hopefully save their data, if somehow this bug makes it past testing. However drag and drop are different - throw an exception from one of these and it will just be silently swallowed with no explanation.  By the way, it's not just drag and drop events. Timer events do it too.  You can research how exceptions are treated in different handlers and code appropriately, but the safest and most user friendly approach is to always catch exceptions in your event handlers and show your own error message. I'll talk about one good approach to handling these exceptions at the end of this post.   2. SSMS integration for SQL Tab Magic  A while back wrote an SSMS add-in called SQL Tab Magic (learn more about the process here). It works by listening to certain SSMS events and remembering what documents are opened and closed. I deployed it internally and it was used for a few months by a number of people without problems, so I was reasonably confident in its quality. Before releasing I made a few cleanups, including introducing error reporting. Bam. A few days later I was looking at over 1,000 error reports in my inbox. In turns out I wasn't handling table designers properly. The exceptions were there, but again SSMS was helpfully swallowing them all for me, so I was blissfully unaware. Had I made my errors loud from the start, I would have noticed these issues long before and fixed them.   Handling exceptions  Now you are systematically catching exceptions throughout your application, you need to do something with them. I've tried 3 options: log them, alert the user, and automatically send them home.  There are a few good options for logging in .NET. The most widespread is Apache log4net, which provides a very capable and configurable logging framework. There is also NLog which has a compatible interface, with a greater emphasis on fluent rather than XML configuration.  Alerting the user serves two purposes. Firstly it means they understand their action has failed to they don't just assume it worked (Silent file copy failure is a problem if you then delete the originals) or that they should keep waiting for a background task to complete. Secondly, it means the users can report the bug to your support team, and then you can fix it. This means the message you show the user should contain the information you need as a developer to identify and fix it. And the user will probably just send you a screenshot of the dialog, so it shouldn't be hidden by scroll bars.  This leads us to the third option, automatically sending error reports home. By automatic I mean with minimal effort on the part of the user, rather than doing it silently behind their backs. The advantage of this is you can send back far more detailed and precise information than you can expect a user to include in an email, and by making it easier to report errors, you make it more likely users will do so.  We do this using a great tool called SmartAssembly (full disclosure: this is a product made by Red Gate). It captures complete stack traces including the values of all local variables and then allows the user to send all this information back with a single click. We also capture log files to help understand what lead up to the error. We then use the free SmartAssembly Sync for Jira to dedupe these reports and raise them as bugs in our bug tracking system.  The combined effect of loud errors during development and then automatic error reporting once software is deployed allows us to find and fix more bugs, correct misunderstandings on how our software works, and overall is a key piece in delivering higher quality software. However it is no substitute for having motivated cunning testers in the building - and we're looking to hire more of those too.   If you found this post interesting you should follow me on twitter.

  • Run On Sentences in Technical Writing

    - by Sean Noodleson Neilan
    This is just a question to think about. When you write technical documentation and programming comments, do you ever find yourself writing run-on sentences in order to be more precise? Is packing more technical information into one sentence better than creating many little sentences each with a little bit of technical information? I know it's better to have lots of little classes in their own little files. Perhaps this doesn't apply to writing?

  • What does it take to successfully run a URL shortener service [on hold]

    - by MxyL
    What are the costs (technology wise) for running a URL shortener service such as bit.ly or anonym.to? For example, if I decided to use an inexpensive shared hosting with "unlimited" bandwidth, would that be feasible? Or would I need a dedicated hosting? I found this question: I want to run a URL shortener for my own usage, what do I need to do?, which makes it easy to set it up, but I'm not too clear what kind of things I need to consider.

  • Windows Azure – Write, Run or Use Software

    - by BuckWoody
    Windows Azure is a platform that has you covered, whether you need to write software, run software that is already written, or Install and use “canned” software whether you or someone else wrote it. Like any platform, it’s a set of tools you can use where it makes sense to solve a problem. The primary location for Windows Azure information is located at http://windowsazure.com. You can find everything there from the development kits for writing software to pricing, licensing and tutorials on all of that. I have a few links here for learning to use Windows Azure – although it’s best if you focus not on the tools, but what you want to solve. I’ve got it broken down here into various sections, so you can quickly locate things you want to know. I’ll include resources here from Microsoft and elsewhere – I use these same resources in the Architectural Design Sessions (ADS) I do with my clients worldwide. Write Software Also called “Platform as a Service” (PaaS), Windows Azure has lots of components you can use together or separately that allow you to write software in .NET or various Open Source languages to work completely online, or in partnership with code you have on-premises or both – even if you’re using other cloud providers. Keep in mind that all of the features you see here can be used together, or independently. For instance, you might only use a Web Site, or use Storage, but you can use both together. You can access all of these components through standard REST API calls, or using our Software Development Kit’s API’s, which are a lot easier. In any case, you simply use Visual Studio, Eclipse, Cloud9 IDE, or even a text editor to write your code from a Mac, PC or Linux.  Components you can use: Azure Web Sites: Windows Azure Web Sites allow you to quickly write an deploy websites, without setting a Virtual Machine, installing a web server or configuring complex settings. They work alone, with other Windows Azure Web Sites, or with other parts of Windows Azure. Web and Worker Roles: Windows Azure Web Roles give you a full stateless computing instance with Internet Information Services (IIS) installed and configured. Windows Azure Worker Roles give you a full stateless computing instance without Information Services (IIS) installed, often used in a "Services" mode. Scale-out is achieved either manually or programmatically under your control. Storage: Windows Azure Storage types include Blobs to store raw binary data, Tables to use key/value pair data (like NoSQL data structures), Queues that allow interaction between stateless roles, and a relational SQL Server database. Other Services: Windows Azure has many other services such as a security mechanism, a Cache (memcacheD compliant), a Service Bus, a Traffic Manager and more. Once again, these features can be used with a Windows Azure project, or alone based on your needs. Various Languages: Windows Azure supports the .NET stack of languages, as well as many Open-Source languages like Java, Python, PHP, Ruby, NodeJS, C++ and more.   Use Software Also called “Software as a Service” (SaaS) this often means consumer or business-level software like Hotmail or Office 365. In other words, you simply log on, use the software, and log off – there’s nothing to install, and little to even configure. For the Information Technology professional, however, It’s not quite the same. We want software that provides services, but in a platform. That means we want things like Hadoop or other software we don’t want to have to install and configure.  Components you can use: Kits: Various software “kits” or packages are supported with just a few clicks, such as Umbraco, Wordpress, and others. Windows Azure Media Services: Windows Azure Media Services is a suite of services that allows you to upload media for encoding, processing and even streaming – or even one or more of those functions. We can add DRM and even commercials to your media if you like. Windows Azure Media Services is used to stream large events all the way down to small training videos. High Performance Computing and “Big Data”: Windows Azure allows you to scale to huge workloads using a few clicks to deploy Hadoop Clusters or the High Performance Computing (HPC) nodes, accepting HPC Jobs, Pig and Hive Jobs, and even interfacing with Microsoft Excel. Windows Azure Marketplace: Windows Azure Marketplace offers data and programs you can quickly implement and use – some free, some for-fee.   Run Software Also known as “Infrastructure as a Service” (IaaS), this offering allows you to build or simply choose a Virtual Machine to run server-based software.  Components you can use: Persistent Virtual Machines: You can choose to install Windows Server, Windows Server with Active Directory, with SQL Server, or even SharePoint from a pre-configured gallery. You can configure your own server images with standard Hyper-V technology and load them yourselves – and even bring them back when you’re done. As a new offering, we also even allow you to select various distributions of Linux – a first for Microsoft. Windows Azure Connect: You can connect your on-premises networks to Windows Azure Instances. Storage: Windows Azure Storage can be used as a remote backup, a hybrid storage location and more using software or even hardware appliances.   Decision Matrix With all of these options, you can use Windows Azure to solve just about any computing problem. It’s often hard to know when to use something on-premises, in the cloud, and what kind of service to use. I’ve used a decision matrix in the last couple of years to take a particular problem and choose the proper technology to solve it. It’s all about options – there is no “silver bullet”, whether that’s Windows Azure or any other set of functions. I take the problem, decide which particular component I want to own and control – and choose the column that has that box darkened. For instance, if I have to control the wiring for a solution (a requirement in some military and government installations), that means the “Networking” component needs to be dark, and so I select the “On Premises” column for that particular solution. If I just need the solution provided and I want no control at all, I can look as “Software as a Service” solutions. Security, Pricing, and Other Info  Security: Security is one of the first questions you should ask in any distributed computing environment. We have certification info, coding guidelines and more, even a general “Request for Information” RFI Response already created for you.   Pricing: Are there licenses? How much does this cost? Is there a way to estimate the costs in this new environment? New Features: Many new features were added to Windows Azure - a good roundup of those changes can be found here. Support: Software Support on Virtual Machines, general support.

  • Auto-run script when iPad plugged in

    - by oldmankit
    The way that Ubuntu handles documents on the iPad is awesome (without any configuration required). It beats windows, even after you install iTunes. I want to have the documents in certain iPad apps automatically synced into my Dropbox directory whenever the iPad is connected by USB. The syncing is easy; getting the script to run is not. I have already read the information in various (very out-of-date) tutorials. The best I could find was here: http://askubuntu.com/a/25091/16157 I used lsusb, with the following results: Bus 002 Device 012: ID 05ac:12a2 Apple, Inc. (Please note that when an iPad is connected, Ubuntu seems to mount it to two different mount points: one for "Documents" and one for the whole iPad filesystem.

  • Frontend development, where to start?

    - by glitch
    I've been stuck on the backend for years now, working on webservices, DBs, SDKs, APIs and all that jazz, and so that's an area that I have a decent grasp of, but I've absolutely no clue about how the frontend works. What's a good place to start for a backend monkey like me who wants to learn the best practices, latest technologies and the philosophy behind modern web page design and its interaction with the server? I want to be cool like all of the other javascript kids. Thanks!

  • How do I start "Ubuntu classic desktop" (no effects) from the command line

    - by Andrew Stern
    I am able to run sessions over an ssh connection but I rather use the "Ubuntu classic desktop (no effects)" version on Ubuntu 11.04 instead of the new Unity since I don't have 3d support on the laptop I'm using to display the graphical User Interface. How can I startup the older gnome-session without the 3d effects? I tried gnome-session but it seems to be the option with the 3d effects and I want a more stripped down session over my ssh session.

I was looking for an answer but nothing worked. Has anybody ideas how to solve it ? It would be really nice to use it as earlier ;)
