  • Newbie, deciding Python or Erlang

    - by Joe
    Hi Guys, I'm a Administrator (unix, Linux and some windows apps such as Exchange) by experience and have never worked on any programming language besides C# and scripting on Bash and lately on powershell. I'm starting out as a service provider and using multiple network/server monitoring tools based on open source (nagios, opennms etc) in order to monitor them. At this moment, being inspired by a design that I came up with, to do more than what is available with the open source at this time, I would like to start programming and test some of these ideas. The requirement is that a server software that captures a stream of data and store them in a database(CouchDB or MongoDB preferably) and the client side (agent installed on a server) would be sending this stream of data on a schedule of every 10 minutes or so. For these two core ideas, I have been reading about Python and Erlang besides ruby. I do plan to use either Amazon or Rackspace where the server platform would run. This gives me the scalability needed when we have more customers with many servers. For that reason alone, I thought Erlang was a better fit(I could be totally wrong, new to this game) and I understand that Erlang has limited support in some ways compared to Ruby or Python. But also I'm totally new to the programming realm of things and any advise would be appreciated grately. Jo

  • Should we enforce code style in our large codebase?

    - by eighttrackmind
    By "code style" I mean 2 things: Style, eg. // bad if(foo){ ... } // good if (foo) { ... } Conventions and idiomaticity, where two ways of writing the same thing are functionally equivalent, but one is more idiomatic. eg. // bad if (fooLib.equals(a, b)) { ... } // good if (a == b) { ... } I think it makes sense to use an auto-formatter to enforce #1 automatically. So my question is specifically about #2. I like to break things down into pros and cons, here's what I've come up with so far: Pros: Used by many large codebases (eg. Google, jQuery) Helps make it a bit easier to work on new areas of the codebase Helps make code more portable (this is not necessarily true) Code style is automatic once you get used to it Makes it easier to fast-decline pull requests Cons: Takes engineers’ and code reviewers’ time away from more important things (like developing features) Code should ideally be rewritten every 2-3 years anyway, so it’s more important to focus on getting the architecture right, and achieving high test coverage Adds strain to code reviews (eg. “don’t do it this way, I like this other way better”) Even if I’ve been using a code style for a while, I still sometime have to pause and think about how to write a line better Having an enforced, uniform code style makes it hard to experiment with potentially better styles Maintaining a style guide takes a lot of incremental effort Engineers rarely read through the style guide. More often, it's cited in code reviews And as a secondary question: we also have many smaller repositories - should the same code style be enforced there?

  • Best book for learning linux shell scripting?

    - by chakrit
    I normally works on Windows machines but on some occasions I do switch to development on linux. And my most recent project will be written entirely on a certain linix platforms (not the standard Apache/MySQL/PHP setup). So I thought it would pay to learn to write some linux automation script now. I can get around the system, start/stop services, compile/install stuffs fine. Those are probably basic drills for a programmer. But if, for example, I wanted to deploy a certain application automatically to a newly minted linux machine every month I'd love to know how to do it. So if I wanted to learn serious linux shell scripting, what book should I be reading? Thanks

  • We have no SW Firewall behind our office HW firewall, admin says its not req'd

    - by Makach
    I've recently changed jobs and I've been set up with a new workstation. On all previous places where I've been working they've had some sort of local firewall installed on each and every workstation - but here I've been told not to activate it because it is not necessary since we're already behind a HW Firewall. To me this seem a bit naïve, but I cannot emphasise it. I always thought a local firewall was good practice, ie. if something managed to come through the hw firewall there might be a slight chance other computers on the lan would block the internal threath. We got free access to internet and we got a virus checker installed.

  • Why are my uWSGI processes dying immediately?

    - by orokusaki
    I'm using Supervisor and the uWSGI Emperor mode. When I set limit-as to 512 (MB), workers die instantly (respawn, die, respawn, die, every 3/4 of a second or so): [uwsgi] workers = 4 threads = 40 limit-as = 512 harakiri = 20 max-requests = 1600 ... non-performance/memory/processor-related settings ommitted But, if I change limit-as to: [uwsgi] workers = 4 threads = 40 limit-as = 1024 harakiri = 20 max-requests = 1600 ... non-performance/memory/processor-related settings ommitted and restart uwsgi, the problem is gone immediately. In order to put a sham in this, I've modified the setting back to 512, restarted again, and the problem is back immediately. Notes: My app is a simple Django app without much additional Python setup during start-up time.

  • How can I recover data after mistakenly clean-installed 12.04 over 11.10?

    - by T.Kannan
    I recently got a Ubuntu 12.04 LTS i386 DVD Rom and Ubuntu 12.04 LTS alternate cd from the zyxware.com because I don't have a broadband personal connection at home, I am using only the office INTERNET. I have a Dell Inspiron Laptop core 2 duo Processor with 2GB Ram dual boot of Ubuntu 11.10 and Windows Vista. I tried to upgrade My existing fully equipped streamlined Ubuntu 11.10 OS with lot of documents and socialized application packages which have been frequently used by me for the last one year. First I tried to install upgradation from the Ubuntu 12.04 LTS alternate cd while ubuntu 11.10 is on, but every time I got a error message and I couldn't upgrade either thro desktop or through terminal. Then I tried Ubuntu 12.04 LTS i386 DVD the boot option to DVD, I tried to upgrade from existing 11.10 to 12.04 LTS Option, then Upgrading Installation started well and finally got a message Installation completed successfully, Asked for reboot, I rebooted then I have hot a Ubuntu 12.04 LTS Login and I logged on, I have got a big shock that there is everything washed away in the home folders ( all datas, Music collections and vedios etc), all the application installed early in 11.10 were gone nothing left. Now I have got only 12.04 LTS, even It is asking for me to update around 350 mb through net connection. How It was a crazy Ubuntu, It is not a up-gradation, new installation is not it? I loosed everthing, at the end I got the same desktop screen like Ubuntu 11.10. Anybody knows about what gone wrong and if any possibility to recover my datas? Please help me. I want to Know that which method is stable to Upgrade existing Ubunt11.10

  • Splwow64 with TS Easy Print

    - by Tim Brigham
    I have an application (Sage MIP Fund Accounting) which exports data to Excel. In this process it uses an internal print driver. Since we upgraded from 2008 to 2008 R2 this export process causes system hangs. This has been isolated down to the splwow64 executable hanging while the Excel document is building. If I kill the spwow64 executable things function properly (I just can't print it once completed). This only occurs while using printer redirection using the Remote Desktop Easy Print function - if I pull the printer redirection things work exactly as expected. I've spent the last couple hours looking at hotfixes or driver upgrades since this appears to be a problem specifically with how the Remote Desktop Easy Printer printer is functioning. Is anyone aware of a hotfix which would be applicable in this situation? I don't want to grab every hotfix for redirected printing and start throwing them out there.

  • Oracle VM Blade Cluster Reference Configuration

    - by Ferhat Hatay
    Today we are happy to announce the availability of the Oracle VM blade cluster reference configuration for Sun Blade 6000 modular systems.  The new Oracle VM blade cluster reference configuration can help reduce the time to deploy virtual infrastructure by up to 98 percent when compared to multi-vendor configurations. Oracle's virtualization strategy is to simplify the deployment, management, and support of the enterprise stack from application to disk. The Oracle VM blade cluster reference configuration is a single-vendor solution that addresses every layer of the virtualization stack with Oracle hardware and software components. It enables quick and easy deployment of the virtualized infrastructure using components that have been tested together and are all supported together by one vendor — Oracle. All components listed in the reference configuration have been tested together by Oracle, reducing the need for customer testing and the time-consuming and complex effort of designing and deploying a stable configuration. Benefitting from pre-installed Oracle VM Server for x86 software on Oracle’s highly scalable and reliable Sun Blade servers with built-in networking and Oracle’s Sun ZFS Storage Appliance product line, the configuration provides high availability via the blade cluster as well as a documented best practice guide that helps reduce deployment time and cost for customers implementing highly virtualized applications or private cloud Infrastructure as a Service (IaaS) architectures. To further support easier, faster and lower-cost deployments, Oracle Linux, Oracle Solaris and Oracle VM are available for pre-install on select Sun x86 systems, and Oracle VM Templates are available for download for Oracle Applications, Oracle Fusion Middleware, Oracle Database, Oracle Real Application Clusters, and many other Oracle products. Key benefits of the Oracle VM blade cluster reference configuration include: Faster time to value – Begin deploying applications immediately because the optimized software stack is pre-configured for best practices and is ready-to-run on the recommended hardware platforms. Reduced deployment cost and risk – The entire hardware and software stack has been tested and is supported together by Oracle. Elastic scalability – As capacity needs grow, the system can be easily scaled in multiple dimensions with the ability to add compute, storage, and networking resources independently. For more information, see: Oracle white paper: Accelerating deployment of virtualized infrastructures with the Oracle VM blade cluster reference configuration Oracle technical white paper: Best Practices and Guidelines for Deploying the Oracle VM Blade Cluster Reference Configuration

  • PhP/HTML play button [migrated]

    - by Marian
    I'm wanting to make my own small webpage, I've got a domain Saoo.eu As you see there is a small play button in the corner witch plays a playlist. Is there anyway to have that playbutton on each page I'd add in the future without resetting every time the page changes? Am I forced to use iFrames for that? This is my player code <button id="audioControl" style="width:30px;height:25px;"></button> <audio id="aud" src="" autoplay autobuffer /> Script: $(document).ready(function() { $('#audioControl').html('II'); if(Modernizr.audio && Modernizr.audio.mp3) { audio.setAttribute("src",'http://daokun.webs.com/play0.mp3'); } else if(Modernizr.audio && Modernizr.audio.wav) { audio.setAttribute("src", 'http://daokun.webs.com/play0.ogg'); } }); var audio = document.getElementById('aud'), count = 0; $('#audioControl').toggle( function () { audio.pause(); $('#audioControl').html('>'); }, function () { audio.play(); $('#audioControl').html('II'); } ); audio.addEventListener("ended", function() { count++; if(count == 4){count = 0;} if(Modernizr.audio && Modernizr.audio.mp3) { audio.setAttribute("src",'http://daokun.webs.com/play'+count+'.mp3'); } else if(Modernizr.audio && Modernizr.audio.wav) { audio.setAttribute("src", 'http://daokun.webs.com/play'+count+'.ogg'); } audio.load(); });

  • SQL SERVER – What is Fill Factor and What is the Best Value for Fill Factor

    - by pinaldave
    Working in performance tuning area, one has to know about Index and Index Maintenance. For any Index the most important property is Fill Factor. Fill factor is the value that determines the percentage of space on each leaf-level page to be filled with data. In an SQL Server, the smallest unit is a page, which is made of  Page with size 8K. Every page can store one or more rows based on the size of the row. The default value of the Fill Factor is 100, which is same as value 0. The default Fill Factor (100 or 0) will allow the SQL Server to fill the leaf-level pages of an index with the maximum numbers of the rows it can fit. There will be no or very little empty space left in the page, when the fill factor is 100. I have written following two article about Fill Factor. What is Fill factor? – Index, Fill Factor and Performance – Part 1 What is the best value for the Fill Factor? – Index, Fill Factor and Performance – Part 2 I strongly encourage read them and provide your feedback.

  • Error in Outlook: "A program has attachment...open" when replying to email

    - by Billious
    Whenever I reply to an email in Outlook 2007, dialogue box pops up saying: "A program has the attachment <email subject> open. Changes to this file will be lost unless you save your changes to another file by clicking the Microsoft Office Button in the other program, and then clicking Save As." This happens whether the original email has an attachment or not. It's just an annoyance really - Outlook works fine in every other respect. It only started happening about a week ago. As far as I can remember I haven't installed any new software that is likely to have affected it.

  • Windows Server 2008 Task Scheduler Tasks Not Executing

    - by omatase
    I've been having an intermittent problem for some time now with the Windows Task Scheduler that I can't work out. I use the task scheduler to run a C# app I've written that has various plugins used to ensure production systems are working. This task scheduler itself is actually a production system so I have one simple task that executes every 8 minutes to notify an external monitoring system that the task scheduler is still up. If this external service fails to receive an "all-clear" at least once every 15 minutes (or so I don't remember the exact number right now) it will message us that the monitoring system is down. In the past we've had intermittent "down" messages from time to time and each time I've investigated the cause I was unable to find any problems. So this time I wanted to ask the StackOverflow community since it doesn't look like I'll have luck on my own. This morning at 2:32 AM the task fired (exactly 8 minutes after the previous firing) however the task didn't fire again until 3:28. There are no errors that I can see in the Event Viewer at this time. When I look at the Task Scheduler log there are no errors there either. Here is what the log looks like though: Information 6/11/2011 3:28:56 AM 102 Task completed (2) d6cf2412-269e-48bf-9f40-4a863347baad Information 6/11/2011 3:28:56 AM 201 Action completed (2)

    Herve Roggero has just published a paper that outlines patterns for scaling using SQL Azure and the Blue Syntax (he and Scott Klein’s company) sharding api. You can find the paper at: http://www.bluesyntax.net/files/EnzoFramework.pdf Herve and Scott have also just released an Apress book Pro SQL Azure. The idea of being able to split (shard) database operations automatically and control them from a web based management console is very appealing. These ideas have been talked about for a long time and implemented in thousands of very custom ways that have been costly, complicated and fragile. Now, there is light at the end of the tunnel. Scaling database access will become easier and move into the mainstream of application development. The main cost is using an api whenever accessing the database. The api will direct the query to the correct database(s) which may be located locally or in the cloud. It is inevitable that the api will change in the future, perhaps incorporated into a Microsoft offering. Even if this is the case, your application has now been architected to utilize these patterns and details of the actual api will be less important. Herve does a great job of laying out the concepts which every developer and architect should be familiar with!

  • Are spurious TCP connections on port 53 a problem?

    - by Darren Greaves
    I run a server which amongst other things uses tinydns for DNS and axfrdns for handling transfer requests from our secondary DNS (another system). I understand that tinydns uses port 53 on UDP and axfrdns uses port 53 on TCP. I've configured axfrdns to only allow connections from my agreed secondary host. I run logcheck to monitor my logs and every day I see spurious connections on port 53 (TCP) from seemingly random hosts. They usually turn out to be from ADSL connections. My question is; are these innocent requests or a security risk? I am happy to block repeat offenders using iptables but don't want to block innocent users of one of the websites I host. Thanks, Darren.

  • "TMGR is Missing" after repair-installing Windows XP

    - by djzmo
    Hello there, I have two OSes installed in my computer. - Windows XP Professional - Windows 7 Ultimate (Release Candidate 1/Build 7100) I used the Windows 7 boot loader by default to choose between OSes. When I was using my WinXP, my computer gets lagged suddenly and continuously, and the only way to fix it is by repair-installing it (because I've experienced this many times before, but without W7 installed). Everything goes OK. But when my XP was successfully reinstalled, I cannot boot my Windows 7 anymore. Every time I tried to boot the harddisk that contains W7, an error appeared. "TMGR is Missing". Now I have no idea how can I get back to my Windows 7. Any kind of help would be appreciated! :)

  • Where Debian Lenny stores initial ifconfig values?

    - by Kuroki Kaze
    With upgrade of VMWare Player I suddenly found my Debian Lenny VM not getting IP address. Some DHCP issue maybe, I don't know. So I have to set it manually every boot in Player window, via: ifconfig eth0 down ifconfig eth0 192.168.175.128 netmask 255.255.255.0 up I usually start up VM and then connect to it via SSH, so this procedure bothers me. Sure I can add it to startup script, but is there some special place to enter these values? Like, some config file or so?

  • 4.5.1 4.4.0 DNS Query Failed

    - by Justin
    We are running Exchange 2010 and lately I have noticed that some outgoing messages get stuck in the queue with the error "451 4.4.0 DNS Query Failed". On every domain that this happens on I have been able to use nslookup to find the MX record and open a connection to their server over SMTP so I am reasonably sure that this problem is on my end. My send connector isn't routing mail through a smart host nor is is set to use a different DNS server to do the lookup so I'm stumped as to why these messages aren't going out. Any ideas?

  • Rails3 environment running very slow on Windows XP, Ubuntu 9.04, Ubuntu 9.10

    - by bergyman
    I've tried all three (granted the Ubuntu versions were via VirtualBox with XP as a host, but I gave the images all the available RAM my system has). Loading the rails environment is taking 30-60 seconds. rails console, rake test:units - anything that requires rails to load up. And not just on the first go - every time. I've even used autotest to see if it helps with execution time for unit tests, but it doesn't. Any time I change one test, it still takes 30 seconds to load them, and then about 4 seconds to execute. Has anyone else come across this issue? Has anyone figured out any way to fix this?

  • Easy Credential Caching for Git

    A common question since launching our Git support is whether there is a way to cache your username and password so you don’t have to enter it on every push.  Well thanks to Andrew Nurse from the ASP.Net team, there is now a great solution for this! Credential Caching in Windows to the Rescue Using the Git extension point for credential caching, Andrew created an integration into the Windows Credentials store. After installing git-credential-winstore instead of getting that standard prompt for a username/password, you will get a Windows Security prompt. From here your credentials for CodePlex will be stored securely within the Windows Credential Store. Setup The setup is pretty easy. Download the application from Andrew's git-credential-winstore project. Launch the executable and select yes to have it prompt for credentials. That's it. Make sure you are running the latest version of msysgit, since the credential's API is fairly new. Thanks to Andrew for sharing his work.  If you have suggestions or improvements you can fork the code here.

  • Ground Control by David Baum

    - by JuergenKress
    As cloud computing moves out of the early-adopter phase, organizations are carefully evaluating how to get to the cloud. They are examining standard methods for developing, integrating, deploying, and scaling their cloud applications, and after weighing their choices, they are choosing to develop and deploy cloud applications based on Oracle Cloud Application Foundation, part of Oracle Fusion Middleware. Oracle WebLogic Server is the flagship software product of Oracle Cloud Application Foundation. Oracle WebLogic Server is optimized to run on Oracle Exalogic Elastic Cloud, the integrated hardware and software platform for the Oracle Cloud Application Foundation family. Many companies, including Reliance Commercial Finance, are adopting this middleware infrastructure to enable private cloud computing and its convenient, on-demand access to a shared pool of configurable computing resources. “Cloud computing has become an extremely critical design factor for us,” says Shashi Kumar Ravulapaty, senior vice president and chief technology officer at Reliance Commercial Finance. “It’s one of our main focus areas. Oracle Exalogic, especially in combination with Oracle WebLogic, is a perfect fit for rapidly provisioning capacity in a private cloud infrastructure.” Reliance Commercial Finance provides loans to tens of thousands of customers throughout India. With more than 1,500 employees accessing the company’s core business applications every day, the company was having trouble processing more than 6,000 daily transactions with its legacy infrastructure, especially at the end of each month when hundreds of concurrent users need to access the company’s loan processing and approval applications.

  • in HFT trading should I upgrade from Windows Server 2008 R2 to Windows Server 2012?

    - by javapowered
    I'm using HP DL360p Gen8 + Windows Server 2008 R2 for HFT trading. That means that every 10 microseconds is important for me. I do understand that if I need everything to be so fast I probably should consider using Linux. But in this post I want to compare only Windows Server 2008 R2 and Windows Server 2012. I've found in internet couple articles that suggest how to tune Windows Server 2012 for low latency http://msdn.microsoft.com/library/windows/hardware/jj248719 http://technet.microsoft.com/en-us/library/hh831415.aspx Most part of optimizations from these articles apply only to Windows Server 2012 and can not be used on Windows Server 2008 R2. So now I think that as I can optimize Windows Server 2012 for low latency, probaly I should upgrade? After optimizations how much faster windows server 2012 would be (ideally in microseconds :)?

  • Start Debugging in Visual Studio

    - by Daniel Moth
    Every developer is familiar with hitting F5 and debugging their application, which starts their app with the Visual Studio debugger attached from the start (instead of attaching later). This is one way to achieve step 1 of the Live Debugging process. Hitting F5, F11, Ctrl+F10 and the other ways to start the process under the debugger is covered in this MSDN "How To". The way you configure the debugging experience, before you hit F5, is by selecting the "Project" and then the "Properties" menu (Alt+F7 on my keyboard bindings). Dependent on your project type there are different options, but if you browse to the Debug (or Debugging) node in the properties page you'll have a way to select local or remote machine debugging, what debug engines to use, command line arguments to use during debugging etc. Currently the .NET and C++ project systems are different, but one would hope that one day they would be unified to use the same mechanism and UI (I don't work on that product team so I have no knowledge of whether that is a goal or if it will ever happen). Personally I like the C++ one better, here is what it looks like (and it is described on this MSDN page): If you were following along in the "Attach to Process" blog post, the equivalent to the "Select Code Type" dialog is the "Debugger Type" dropdown: that is how you change the debug engine. Some of the debugger properties options appear on the standard toolbar in VS. With Visual Studio 11, the Debug Type option has been added to the toolbar If you don't see that in your installation, customize the toolbar to show it - VS 11 tends to be conservative in what you see by default, especially for the non-C++ Visual Studio profiles. Comments about this post by Daniel Moth welcome at the original blog.

  • Running a scheduled task as SYSTEM with console window open

    - by raoulsson
    I am auto creating scheduled tasks with this line within a batch windows script: schtasks /Create /RU SYSTEM /RP SYSTEM /TN startup-task-%%i /TR %SPEEDWAY_DIR%\%TARGET_DIR%%%i\%STARTUPFILE% /SC HOURLY /MO 1 /ST 17:%%i1:00 I wanted to avoid using specific user credentials and thus decided to use SYSTEM. Now, when checking in the taskmanagers process list or, even better, directly with the C:\> schtasks command itself, all is working well, the tasks are running as intended. However in this particular case I would like to have an open console window where I can see the log flying by. I know I could use C:\> tail -f thelogfile.log if I installed e.g. cygwin (on all machines) or some proprietary tools like Baretail on Windows. But since I only switch to these machines in case of trouble, I would prefer to start the scheduled task in such a way that every user immediately sees the log. Any chance? Thanks!
