  • How do you avoid that server documentation gets out of sync with the actual setup?

    - by Frerich Raabe
    I'm a hobbyist maintaining a small FreeBSD server serving mail via IMAP - it's an exercise in server administration. The setup does have reasonably good documentation (in AsciiDoc format) which recently allowed another person to recreate the entire setup from scratch in less than 30 minutes. However, I noticed that after the initial setup, it easily happens that small changes done to the system (say: inetd gets disabbled, my IMAP server listens on an additional port for ManageSieve connections, a new router is added to the exim configuration) don't end up in the documentation immediately (if at all). My idea was to avoid this problem by (partially?) generating the documentation out of the configuration files and the comments therein - one way to implement this may be to put /etc and /usr/local/etc into some source code management system (say - git) and then run a script which regenerates the documentation on every commit. However, I'm not sure whether that would be overkill and/or too difficult to get right (after all, I don't want complete copies of the source files in my documentation but rather just the diffs). How do other people avoid that the server documentation gets outdated - is there a good way to keep them in sync automatically, or do you just have the discipline to update the documentation the same time you modify the system?

  • Is there any functional-like unix shell?

    - by Caruccio
    I'm (really) newbie to functional programming (in fact only had contact with it using python) but seems to be a good approach for some list-intensive tasks in a shell environment. I'd love to do something like this: $ [ git clone $host/$repo for repo in repo1 repo2 repo3 ] Is there any Unix shell with these kind of feature? Or maybe some feature to allow easy shell access (commands, env/vars, readline, etc...) from within python (the idea is to use python's interactive interpreter as a replacement to bash). EDIT: Maybe a comparative example would clarify. Let's say I have a list composed of dir/file: $ FILES=( build/project.rpm build/project.src.rpm ) And I want to do a really simple task: copy all files to dist/ AND install it in the system (it's part of a build process): Using bash: $ cp ${files[*]} dist/ $ cd dist && rpm -Uvh $(for f in ${files[*]}; do basename $f; done)) Using a "pythonic shell" approach (caution: this is imaginary code): $ cp [ os.path.join('dist', os.path.basename(file)) for file in FILES ] 'dist' Can you see the difference ? THAT is what i'm talking about. How can not exits a shell with these kind of stuff build-in yet? It's a real pain to handle lists in shell, even its being a so common task: list of files, list of PIDs, list of everything. And a really, really, important point: using syntax/tools/features everybody already knows: sh and python. IPython seams to be on a good direction, but it's bloated: if var name starts with '$', it does this, if '$$' it does that. It's syntax is not "natural", so many rules and "workarounds" ([ ln.upper() for ln in !ls ] -- syntax error)

  • Does OS X support linux-like features?

    - by Xeoncross
    I have been using XP for almost a decade. Contrary to popular belief, it has served me well. In the last 4 years I don't remember ever having it crash on me. It has the most stable GUI I have ever used. However, an OS is only as good as it's GUI AND command line combined. Windows command line is awful and totally useless. So I have been using Ubuntu for a couple years and Debian on my servers. The only problem is that Gnome applications (ubuntu 6-10) constantly crash on me (Ubuntu Studio was the most unstable OS I ever used). I have high quality Gigabyte, MSI, and Asus motherboards and CPU's from old Semprons/Athlons to Celerons/Core 2 Quads. What are the odds that every PC I have ever owned can't remain stable with a linux GUI? Not to mention that Adobe CSx Suite doesn't work on linux. Anyway, I am now looking at moving to a MAC in the hope of finding a stable GUI and a feature-packed command line. Does Mac OS have an integrated command line where I can do linux-like-awesomeness like rsync, ssh, wget, crong jobs, package updates, and git without having an unstable GUI? Basically, until the linux GUI applications get a little better, is OS X what I need?

  • How to deploy new instances of the same application (on 1 server) automatically?

    - by Intru
    I'm working on a SaaS application where each customer runs its own version of the application. All the application instances currently run on a single server. This works quite well for us (we need less resources in total). The application doesn't use a lot of resources, so even a small VPS would be overkill (and more expensive). Adding a new customer is currently quite a bit of work: Create a user that is allowed to ssh Create a new MySQL database and user Create a virtual host for the application Log in with the new user, do a git checkout of the application (in the right location) Create tables in the new database, and add some init data Add some cron jobs Create a first user that can log in Add this new instance to capistrano What would be the best way to automate these tasks? Are the applications that can (given proper configuration) do this? Ideally this should be usable for a sales-person (so something web-based). I could write a (bash) script that does most of these tasks, and then maybe add a small web-based wrapper where someone could provider the domain/default user information. Of course, this would also require a delete-script, since some customers will eventually leave, which means that you need a list of all existing customers/instances.

  • Windows 8 Killed my SSDs

    - by SLaks
    I have a computer running 2 256GB Crucial M4's (CT256M4SSD2) in a RAID 0 (striped) array on an ASUS P9X79 Pro using Intel's (built-in) RAID system. I recently installed Windows 8 Pro as UEFI on this RAID array. (wiping a fully-function Windows 7 non-UEFI installation) Now, whenever the computer is left running for about an hour, the system no longer sees those drives. Since those drives contain Windows, this leads to various forms of BSODs. If I Intel RSTe (RAID manager) is running at the time, it will say that the disk backing that RAID array has been removed. Once this happens, if I reset the computer, it will no longer boot. Entering BIOS setup shows that the SATA 3 (6Gbps) ports that those disks are connected to are both empty. If I then power down the system completely, then turn it on again, the drives reappear, but the problem repeats after another hour or so. I have inconclusively determined that the problem occurs even if Windows is not running (booted into the installation environment from a UEFI flash drive) I don't think there has been any data corruption since this started happening, although I have had two strange issues with a GIT repo on that disk. sfc /ScanNow and Intel's disk check (in RSTe) both do not find anything. Does anyone know what might cause this?

  • Deploying Memcached as 32bit or 64bit?

    - by rlotun
    I'm curious about how people deploy memcached on 64 bit machines. Do you compile a 64bit (standard) memcached binary and run that, or do people compile it in 32bit mode and run N instances (where N = machine_RAM / 4GB)? Consider a recommended deployment of Redis (from the Redis FAQ): Redis uses a lot more memory when compiled for 64 bit target, especially if the dataset is composed of many small keys and values. Such a database will, for instance, consume 50 MB of RAM when compiled for the 32 bit target, and 80 MB for 64 bit! That's a big difference. You can run 32 bit Redis binaries in a 64 bit Linux and Mac OS X system without problems. For OS X just use make 32bit. For Linux instead, make sure you have libc6-dev-i386 installed, then use make 32bit if you are using the latest Git version. Instead for Redis <= 1.2.2 you have to edit the Makefile and replace "-arch i386" with "-m32". If your application is already able to perform application-level sharding, it is very advisable to run N instances of Redis 32bit against a big 64 bit Redis box (with more than 4GB of RAM) instead than a single 64 bit instance, as this is much more memory efficient. Would not the same recommendation also apply to a memcached cluster?

  • Databases in Source Control

    - by Grant Fritchey
    I’ve been working as a database professional for quite a long time. But originally, I was a developer. And I loved being a developer. There was this constant feedback loop of a job well done, your code compiled and it ran. Every time this happened successfully, you’d check it into source control. These days you have to add another step; the code passed all the tests, unit, line, regression, qa, whatever, then into source control it goes. As a matter of fact, when I first made the jump from developer to DBA/database developer/database professional, source control was the one thing I couldn’t believe was missing from the DBA toolbox. Come to find out, source control was only the beginning of what was missing from your standard DBAs set of skills. Don’t get me wrong. I’m not disrespecting the DBA. They’re focused where they should be, on your production data. But there has to be a method for developing applications that include databases and the database side of that development and deployment process has long been lacking. This lack of development and deployment methodologies is a part of what has given rise to some of the wackier implementations of Object Relational Mapping tools, the NoSQL movement, and some of the other foul cursing that is directed towards databases, DBAs, and database development by application developers. Some of that is well earned. A lot isn’t. But it is a fact that database professionals, in general, do not have as sophisticated a model for managing development and deployment as application developers do. We could charge out and start trying to come up with our own standards and methods. I’m sure people have done exactly that. However, I’m lazy, and not terribly bright. Rather than try to invent a whole new process, I’m going to look to my developer roots and choose instead to emulate the developers. They’re sitting over there across the hall from me working with SCRUM/Agile/Waterfall/Object Driven/Feature Driven/Test Driven development processes that they’ve been polishing for years. What if I just started working on database development the same way they work on code development? Win! Ah, but now I have to have a mechanism for treating my database like application code. First, I need a method for getting it into source control. That’s where Red Gate’s SQL Source Control comes into the picture. SQL Source Control works within SQL Server Management Studio to connect your database objects up to the source control system of your choice. Right out of the box SQL Source Control can link to TFS, SVN or Vault. With a little work you can connect it to Git or just about any other source control system. With the ability to get my database into source control, a lot of possibilities for more direct integration with the application development teams open up.

If I upgrade to "Ubuntu 14.04 'Trusty Tahr'" what advantage I'll get from web developer's point of view? Will the upgrade be hassle free and will I be ablr to continue my on-going work without any difficulties? Is "Ubuntu 14.04 'Trusty Tahr'" a LTS version and if yes till when it's going to provide support? These are the five crucial queries I have. If you want any further explanation from me please feel free to ask me. Thanks for spending some of your vaulable time in reading and understanding my issue. Any kind of help/comment/suggestion/answer would be highly appreciated. Though if someone gives canonical, precise and up to the mark answer, it will be of great help to me as well as other web developers using Ubuntu around the world. Once again thank you so much you great people around the globe. Waiting for your precious replies.

  • St. Louis ALT.NET

    - by Brian Schroer
    I’m a huge fan of the St. Louis .NET User Group and a regular attendee of their meetings, but always wished there was a local group that discussed more advanced .NET topics. (That’s not a criticism of the group - I appreciate that they want to server developers with a broad range of skill levels). That’s why I was thrilled when Nicholas Cloud started a St. Louis ALT.NET group in 2010. Here’s the “about us” statement from the group’s web site: The ALT.NET community is a loosely coupled, highly cohesive group of like-minded individuals who believe that the best developers do not align themselves with platforms and languages, but with principles and ideas. In 2007, David Laribee created the term "ALT.NET" to explain this "alternative" view of the Microsoft development universe--a view that challenged the "Microsoft-only" approach to software development. He distilled his thoughts into four key developer characteristics which form the basis of the ALT.NET philosophy: You're the type of developer who uses what works while keeping an eye out for a better way. You reach outside the mainstream to adopt the best of any community: Open Source, Agile, Java, Ruby, etc. You're not content with the status quo. Things can always be better expressed, more elegant and simple, more mutable, higher quality, etc. You know tools are great, but they only take you so far. It's the principles and knowledge that really matter. The best tools are those that embed the knowledge and encourage the principles (e.g. Resharper.) The St. Louis ALT.NET meetup group is a place where .NET developers can learn, share, and critique approaches to software development on the .NET stack. We cater to the highest common denominator, not the lowest, and want to help all St. Louis .NET developers achieve a superior level of software craftsmanship. I don’t see a lot of ALT.NET talk in blogs these days. The movement was harmed early on by the negative attitudes of some of its early leaders, including jerk moves like the Entity Framework “vote of no confidence”, but I do see occasional mentions of local groups like the St. Louis one. I think ALT.NET has been successful at bringing some of its ideas into the .NET world, including heavily influencing ASP.NET MVC and raising the general level of software craftsmanship for developers working on the Microsoft stack. The ideas and ideals live on, they’re just not branded as “this is ALT.NET!” In the past 18 months, St. Louis ALT.NET meetups have discussed topics like: NHibernate F# and other functional languages AOP CoffeeScript “How Ruby Is Making Me a Stronger C# Developer” Using rake for builds CQRS .NET dynamic programming micro web frameworks – Nancy & Jessica Git ALT.NET doesn’t mean (to me, anyway) “alternatives to .NET”, but “alternatives for .NET”. We look at how things are done in Ruby and other languages/platforms, but always with the idea “What can I learn from this to take back to my “day job” with .NET?”. Meetings are held at 7PM on the fourth Wednesday of each month at the offices of Professional Employment Group. PEG is located at 999 Executive Parkway (Suite 100 – lower level) in Creve Coeur (South of Olive off of Mason Road - Here's a map). Food is not supplied (sorry if you’re a big fan of the Papa John’s Crust-Lovers’ Pizza that’s a staple of user group meetings), but attendees are encouraged to come early and bring/share beer, so that’s cool. Thanks to Nick for organizing, and to Professional Employment Group for lending their offices. Please visit the meetup site for more information.

  • Url rewrite subfolder to root and forbid accessing subfolder

  • Welcome 2011

    - by PSteele
    About this time last year, I wrote a blog post about how January of 2010 was almost over and I hadn’t done a single blog post.  Ugh…  History repeats itself. 2010 in Review If I look back at 2010, it was a great year in terms of technology and development: Visited Redmond to attend the MVP Summit in February.  Had a great time with the MS product teams and got to connect with some really smart people. Continued my work on Visual Studio Magazine’s “C# Corner” column.  About mid-year, the column changed from an every-other-month print column to an every-other-month print column along with bi-monthly web-only articles.  Needless to say, this kept me even busier and away from my blog. Participated in another GiveCamp!  Thanks to the wonderful leadership of Michael Eaton and all of his minions, GiveCamp 2010 was another great success.  Planning for GiveCamp 2011 will be starting soon… I switched to DVCS full time.  After years of being a loyal SVN user, I got bit by the DVCS bug.  I played around with both Mercurial and Git and finally settled on Mercurial.  It’s seamless integration with Windows Explorer along with it’s wealth of plugins made me fall in love.  I can’t imagine going back and using a centralized version control system. Continued to work with the awesome group of talent at SRT Solutions.  Very proud that SRT won it’s third consecutive FastTrack award! Jumped off the BlackBerry train and enjoying the smooth ride of Android.  It was time to replace the old BlackBerry Storm so I did some research and settled on the Motorola DroidX.  I couldn’t be happier.  Android is a slick OS and the DroidX is a sweet piece of hardware.  Been dabbling in some Android development with both Eclipse and IntelliJ IDEA (I like IntelliJ IDEA a lot better!).   2011 Plans On January 1st I was pleasantly surprised to get an email from the Microsoft MVP program letting me know that I had received the MVP award again for my community work in 2010.  I’m honored and humbled to be recognized by Microsoft as well as my peers! I’ll continue to do some Android development.  I’m currently working on a simple app to get me feet wet.  It may even makes it’s way into the Android Market. I’ve got a project that could really benefit from WPF so I’ll be diving into WPF this year.  I’ve played around with WPF a bit in the past – simple demos and learning exercises – but this will give me a chance to build an entire application in WPF.  I’m looking forward to the increased freedom that a WPF UI should give me. I plan on blogging a lot more in 2011! Technorati Tags: Android,MVP,Mercurial,WPF,SRT,GiveCamp

  • Managing Scripts in Oracle SQL Developer

    - by thatjeffsmith
    You backup your databases, right? You backup you home computer – your media collection, tax documents, bank accounts, etc, right? You backup your handy-dandy SQL scripts, right? Ok, now that I’ve got your head nodding, I want to answer a question I get every so often: How can I manage my scripts in SQL Developer? This is an interesting question. First, it assumes that one SHOULD manage their scripts in their IDE. Now, what I think the question generally gets around to is, how can we: Navigate to our scripts Open them Execute them What a good IDE should have is an interface to your existing Version Control System (VCS.) SQL Developer supports out-of-the-box both Subversion and Git. You can also download an extension via check-for-updates to get support for CVS. Now, what I’m about to show you COULD be done without versioning and controlling your scripts – but I want to ask you why you wouldn’t want to do this? So, I’m going to proceed and assume that you do INDEED version your scripts already. Seeing what scripts you’ve already got in your repository This is very straightforward – just open the Team Versions panel. Then connect to your repository. Shows you the files in your source control system. Now, I could ‘preview’ said file right away. If I open the file from here, we get a temp file copy down from the server to the local machine. This is a local temp copy of the controlled script – I can read/execute, but not write to it. And that might be all you need. But, if your script calls other scripts, then you’re going to want to check out the server copy of your stuff down your local SVN working copy directory. That way when your script calls another script – you’re executing the PRODUCTION APPROVED copies of said scripts. And if you do SPOOL or other file I/O stuff, it will work as expected. To get to those said client copies of your scripts… Enter the Files Panel The Files panel is accessible from the View menu. You can get to your files, one of two ways. If you’ve touched the file recently, you can see it under the Recent tree. Otherwise, you can navigate to your local ‘checked out’ copies of your script(s). Open your local copies, see what’s changed, etc. And I can access the change history and see what’s been touched… What changes am I going to ‘push out’ if I commit this back to the server? Most of us work on teams, yes? This panel also gives me a heads up if someone else is making changes to the same file. I can see the ‘incoming’ changes as well. To Sum It Up… If I want to get a script to run: do a full get to your local directory open the script(s) The files panel will tell you if your local copy is out of date from the server and if you have made local changes you’ve forgotten to commit back up to the server and your fellow teammates. Now, if you’re the selfish type and don’t want to share, that’s fine. But you should still be backing up your scripts, and you can still use the Files panel to manage your scripts.

  • ArchBeat Link-o-Rama Top 10 for September 9-15, 2012

    - by Bob Rhubart
    The Top 10 most-viewed items shared on the OTN ArchBeat Facebook page for the week of September 9-15, 2017. 15 Lessons from 15 Years as a Software Architect | Ingo Rammer In this presentation from the GOTO Conference in Copenhagen, Ingo Rammer shares 15 tips regarding people, complexity and technology that he learned doing software architecture for 15 years. Attend OTN Architect Day – by Architects, for Architects – October 25 You won't need 3D glasses to take in these live presentations (8 sessions, two tracks) on Cloud computing, SOA, and engineered systems. And the ticket price is: Zero. Nothing. Absolutely free. Register now for Oracle Technology Network Architect Day in Los Angeles. Thursday October 25, 2012, 8:00 a.m. – 5:00 p.m. Sofitel Los Angeles , 8555 Beverly Boulevard , Los Angeles, CA 90048. Cloud API and service designers, stop thinking small | Cloud Computing - InfoWorld "The focus must shift away from fine-grained APIs that provide some type of primitive service, such as pushing data to a block of storage or perhaps making a request to a cloud-rooted database," says InfoWorld's David Linthicum. "To go beyond primitives, you must understand how these services should be used in a much larger architectural context. In other words, you need to understand how businesses will employ these services to form real workplace solutions—inside and outside the enterprise." Adding a runtime picker to a taskflow parameter in WebCenter | Yannick Ongena Oracle ACE Yannick Ongena shows how to create an Oracle WebCenter popup to allow users to "select items or do more complex things." Oracle IAM 11g R2 docs are now available "One of the great things about the new doc set is the inclusion of ePub files," says Fusion Middleware A-Team blogger Chris Johnson. "This means that if you have an iPad you can load up the doc library onto that and read the docs on the couch." Setting up a local Yum Server using the Exalogic ZFS Storage Appliance | Donald A concise technical post from the man named Donald. What's New in Oracle VM VirtualBox 4.2? | The Fat Bloke Sings "One of the trends we've seen is that as the average host platform becomes more powerful, our users are consistently running more and more vm's," says The Fat Bloke. "Some of our users have large libraries of vm's of various vintages, whilst others have groups of vm's that are run together as an assembly of the various tiers in a multi-tiered software solution, for example, a database tier, middleware tier, and front-ends." The new VirtualBox release, a year in the making, addresses the needs of these users, he explains. Configuring Oracle Business Intelligence 11g MDS XML Source Control Management with Git Version Control | Christian Screen Oracle ACE Christian Screen developed this tutorial for those interested in learning how to configure the Oracle Business Intelligence 11g (11.1.1.6) metadata repository for development using the new MDS XML source control management functionality. Identity and Access Management at Oracle Open World 2012 | Brian Eidelman Fusion Middleware A-Team blogger Brian Eideleman highlights three Oracle Openworld sessions that will put Identity and Access Management in the spotlight, and shares a link to the "Focus On: Identity Management" document, a comprehensive listing of Openworld activities also dealing with IM. Starting and stopping WebLogic automatically using Upstart | Chris Johnson "In Ubuntu, RedHat and Oracle Linux there's a new flavor of init called Upstart that all the kids are using," says Oracle Fusion Middleware A-Team member Chris Johnson. "It's the new hotness when it comes to making programs into daemons and wiring them to start and stop at appropriate times." Thought for the Day "The purpose of software engineering is to control complexity, not to create it." — Pamela Zave Source: SoftwareQuotes.com

  • Azure Web Sites FTP credentials

    - by Bertrand Le Roy
    A quick tip for all you new enthusiastic users of the amazing new Azure. I struggled for a few minutes finding this, so I thought I’d share. The Azure dashboard doesn’t seem to give easy access to your FTP credentials, and they are not the login and password you use everywhere else. What Azure does give you though is a Publish Profile that you can download: This is a plain XML file that should look something like this: <publishData> <publishProfile profileName="nameofyoursite - Web Deploy" publishMethod="MSDeploy" publishUrl="waws-prod-blu-001.publish.azurewebsites.windows.net:443" msdeploySite="nameofyoursite" userName="$NameOfYourSite" userPWD="sOmeCrYPTicL00kIngStr1nG" destinationAppUrl="http://nameofyoursite.azurewebsites.net" SQLServerDBConnectionString="" mySQLDBConnectionString="" hostingProviderForumLink="" controlPanelLink="http://windows.azure.com"> <databases/> </publishProfile> <publishProfile profileName="nameofyoursite - FTP" publishMethod="FTP" publishUrl="ftp://waws-prod-blu-001.ftp.azurewebsites.windows.net/site/wwwroot" ftpPassiveMode="True" userName="nameofyoursite\$nameofyoursite" userPWD="sOmeCrYPTicL00kIngStr1nG" destinationAppUrl="http://nameofyoursite.azurewebsites.net" SQLServerDBConnectionString="" mySQLDBConnectionString="" hostingProviderForumLink="" controlPanelLink="http://windows.azure.com"> <databases/> </publishProfile> </publishData> .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } I’ve highlighted the FTP server name, user name and password. This is what you need to use in Filezilla or whatever you use to access your site remotely. Notice how the password looks encrypted. Well, it’s not really encrypted in fact. This is your password in clear text. It’s just crypto-random gibberish, which is the best kind of password. UPDATE: About 2 minutes after I posted that, David Ebbo mentioned to me on Twitter that if you've configured publishing credentials (for Git typically) those will work too. Don't forget to include the full user name though, which should be of the form nameofthesite\username. The password is the one you defined. That’s it. Enjoy.

  • Can someone explain the true landscape of Rails vs PHP deployment, particularly within the context of Reseller-based web hosting (e.g., Hostgator)?

    - by rcd
    Currently, I have a reseller account with the company HostGator. I design websites, which up until now have occasionally been wrapped in Wordpress CMSs and the like (PHP applications). I then sell hosting (of the site I've designed) to the client, which is pretty simple, in that I can simply click a button and add a new shared hosting account/site with whatever settings I want. Furthermore, I then utilize WHMCS to automate billing and account management. It's a nice package and pretty simple. I pay something like $25 a month, and can sell a hundred accounts under this (because my clients bandwidth requirements are low). Now I am finding the need to develop more customized applications, including a minimalist CMS and several proprietary things. I soon anticipate developing these apps for clients as well. Thus, I've spent the past few months learning Rails, and it's coming along well now. The thing that has nagged at me all along, though, is the deployment issue. I can't wrap my brain around it. It seems like all of the popular options (Heroku, etc) have nice automation with git and are set up in the "Rails Way". I get that (sort of). But it's terribly expensive... a single dyno, a helper, and the cheapest database (which they say is mainly suitable for testing) that isn't limited to 5MB runs $51. This is for ONE app!!! Throw in a "production" DB and you're over $200. This is like... the same prices as getting a server somewhere, right? Meanwhile, going back to what I guess is a "traditional" hosting environment with Hostgator, their server only has Ruby 1.8.7 and Rails 2.3.5... No Rails 3. AND, no Passenger (not that I really understand the difference in CGI or mod_rails or whatever, but they say Passenger is the simplest). So I'm to understand that if I build an app in Rails 3, it won't run at all on this host? But damn, I already have these accounts under my reseller account there, all running static html and/or PHP stuff, right? So what now? How do I get all of this under one simple (and affordable) roof? Forgive my ignorance, but I just don't get it. Managing a VPS is cool and all, but entails learning server admin stuff and security... And it's expensive. I get that a shared and/or reseller "server-based" (forgive the terminology) may be inadequate for large-scale apps that use a lot of bandwidth... But what about for those of us who are building real (but small and low bandwidth) apps (with Rails) and who want to deploy them simply, cheaply, using the same conceptual approach as PHP? Even after learning all of this Ruby and Rails stuff for months, I'm questioning whether it's worth it when it comes to deployment. I want to build a small app, upload it to my home directory on a shared server account, and just make it run. Why should that be so hard? Am I just choosing the wrong language/framework? Forgive my ignorance in the subject; these questions are not rhetorical; just trying to learn here. So: 1) I'd appreciate if someone could give me a good rundown of how to understand deployment in Rails vs. PHP. 2) I'd appreciate if someone could address my issue with running a hosting/web business around reseller hosting (Hostgator) while also being able to host Rails apps. Can it be done? And how can a company like Hostgator completely ignore what's current in Rails/Ruby? Thanks.

  • Chef-solo cannot locate an nginx recipe template

    - by crftr
    I have been recently experimenting with Chef. I thought I would attempt to rebuild my personal web server using chef-solo. It's an AWS instance running the Amazon 64bit Linux AMI. My first objective is to install nginx. I have cloned the Opscode cookbook repository, and am using their nginx cookbook. My problem appears to be that chef-solo cannot find a template after it has started the process. The command I'm using is chef-solo -j /etc/chef/dna.json dna.json { "nginx": { "user": "ec2-user" }, "recipes": [ "nginx" ] } solo.rb file_cache_path "/var/chef-solo" cookbook_path "/var/chef-solo/cookbooks" ...the output [root@ip-10-202-221-135 chef-solo]# chef-solo -j /etc/chef/dna.json /usr/lib64/ruby/gems/1.9.1/gems/systemu-2.2.0/lib/systemu.rb:29: Use RbConfig instead of obsolete and deprecated Config.

  • ASP.NET MVC tries to load older version of Owin assembly

    - by d_mcg
    As a bit of context, I'm developing an ASP.NET MVC 5 application that uses OAuth-based authentication via Microsoft's OWIN implementation, for Facebook and Google only at this stage. Currently (as of v3.0.0, git-commit 4932c2f), the FacebookAuthenticationOptions and GoogleOAuth2AuthenticationOptions don't provide any property to force Facebook nor Google respectively to reauthenticate users (via appending the appropriate query string parameters) when signing in. Initially, I set out to override the following classes: FacebookAuthenticationOptions GoogleOAuth2AuthenticationOptions FacebookAuthenticationHandler (specifically AuthenticateCoreAsync()) GoogleOAuth2AuthenticationHandler (specifically AuthenticateCoreAsync()) yet discovered that the ~AuthenticationHandler classes are marked as internal. So I pulled a copy of the source for the Katana project (http://katanaproject.codeplex.com/) and modified the source accordingly. After compiling, I found that there are several dependencies that needed updating in order to use these updated assemblies (Microsoft.Owin.Security.Facebook and Microsoft.Owin.Security.Google) in the MVC project: Microsoft.Owin Microsoft.Owin.Security Microsoft.Owin.Security.Cookies Microsoft.Owin.Security.OAuth Microsoft.Owin.Host.SystemWeb This was done by replacing the existing project references to the 3.0.0 versions and updating those in web.config. Good news: the project compiles successfully. In debugging, I received an exception on startup: An exception of type 'System.IO.FileLoadException' occurred in [MVC web assembly].dll but was not handled in user code Additional information: Could not load file or assembly 'Microsoft.Owin.Security, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) The underlying exception indicated that Microsoft.AspNet.Identity.Owin was trying to load v2.1.0 of Microsoft.Owin.Security when calling app.UseExternalSignInCookie() from Startup.ConfigureAuth(IAppBuilder app) in Startup.Auth.cs. Unfortunately that assembly (and its other dependency, Microsoft.AspNet.Identity.Owin) aren't part of the Project Katana solution, and I can't find any accessible repository for these assemblies online. Are the Microsoft.AspNet.Identity assemblies open source, like the Katana project? Is there a way to fool those assemblies to use the referenced v3.0.0 assemblies instead of v2.1.0? The /bin folder contains the 3.0.0 versions of the Owin assemblies. I've upgraded the NuGet packages for Microsoft.AspNet.Identity.Owin, and this is still an issue. Any ideas on how to resolve this issue?

  • Wrapping malloc - C

    - by Appu
    I am a beginner in C. While reading git's source code, I found this wrapper function around malloc. void *xmalloc(size_t size) { void *ret = malloc(size); if (!ret && !size) ret = malloc(1); if (!ret) { release_pack_memory(size, -1); ret = malloc(size); if (!ret && !size) ret = malloc(1); if (!ret) die("Out of memory, malloc failed"); } #ifdef XMALLOC_POISON memset(ret, 0xA5, size); #endif return ret; } Questions I couldn't understand why are they using malloc(1)? What does release_pack_memory does and I can't find this functions implementation in the whole source code. What does the #ifdef XMALLOC_POISON memset(ret, 0xA5, size); does? I am planning to reuse this function on my project. Is this a good wrapper around malloc? Any help would be great.

  • recent cvs cygwin newline windows problems. How to solve?

    - by user72150
    Hi all, One of our projects still uses CVS. Recently (sometime in the past year) the Cygwin cvs client (currently using 1.12.13) has given me problems when I update. I suspect the problem stems from windows/unix newline differences. It worked for years without a problem. Here are the symptoms. When I update from the command line, I see messages like these: "no such repository" messages /cvshome : no such repository False-"Modified" due to newline differences M java/com/foo/ekm/value/EkmContainerInstance.java False-"Conflicts" cvs update: Updating java/com/foo/ekm/value/XWiki cvs update: move away `java/com/foo/ekm/value/XWiki/XWikiContainerInstance.java'; it is in the way C java/com/foo/ekm/value/XWiki/XWikiContainerInstance.java Note the for the 'no such repository' error, I found that cd-ing into the 'CVS/' folder and running 'dos2unix Root' updates correctly. I'm not sure how this file (or Repository or Entries) gets whacked. I don't remember when these problems started. I have a workaround: updating from our IDE (Intellij Idea) always succeeds Yes, I know we should switch to (svn|git|mercurial), but does anyone know what causes these problems? when they were introduced? workarounds? thanks, bill

  • emacs frustration with web development any working dot-files?

    - by Tony Cruise
    I really liked flexibility of emacs but it is really annoying to make it work. I want to use it for web development html, css, javascript, php. I first tried emacs-starter-kit . It didn't included nXhtml. Also C-g key binding does not work (they call it starter kit but basic key command does not work). I think it is mapped for git control. That's a frustration for a beginner. Then I replaced emacs-starter-kit with nXhtml. At least C-g is working. But code completion sucks, M-tab does not work. I tried code completion from nXhtml menu with no success. Also NXhtml mode did'nt colorized my file if css is mixed with html. Isn't it recommended for mixed html, css,php files. So why it doesnt work?. Why Emacs folks do not aware of convention over configuration? Dam! ship it something works! Please help me before I am getting crazy. I use Ubuntu 10.04 and emacs-snaphot-gtk 23.1.50-1. Please guide me step by step with your working dotfile url. Even I accept I am a dummy, it is really annoying and frustrating to use emacs.

  • Fail to load NPAPI plugin in Google Chrome on Mac OS X

    - by Roman
    I have been trying to get Google Chrome (6.0.401.1 dev) on Mac OS X to load an NPAPI plugin without success so far. I have been working around the npsimple example from here: http://git.webvm.net/?p=npsimple. Using gcc on Mac and VC++ 2008 on Windows I managed to get it running on Safari and Firefox on Mac OS X and Firefox and Google Chrome on Windows, but not on Google Chrome on Mac OS X. When trying to debug Google Chrome on Mac OS X it seemed Google Chrome was briefly dyld-loading (and immediately dyld-unloading) the plugin on startup, but without actually looking-up any symbols within the plugin or calling any of the functions. It seemed to be doing that for every plugin, though. Also, when loading a page with the embed-tag for the plugin, Google Chrome did not seem to even dyld-load the plugin and no functions were called (not even NP_GetEntryPoints). Google Chrome also does not output any error message, it just simply does not load the plugin. I am not sure I caught everything with gdb because of Google Chrome using different processes, but I have also tried all the switches like --no-sandbox, --single-process and --plugin-startup-dialog (which incidentally does not seem to work at all on Mac OS X). I also made sure the architecture of the binary matches (i.e. 32-bit for Google Chrome). Has anybody had similar problems before? Is there anything I am missing here, like a gcc switch when compiling or something? Any help would be greatly appreciated.

  • Converting from CVS to SVN to Hg, does 'hg convert' require pointing to an SVN checkout or just a re

    - by Terry
    As part of migrating full CVS history to Hg, I've used cvs2svn to create an SVN repo in a local directory. It's first level directory structure is: 2010-04-21 09:39 AM <DIR> . 2010-04-21 09:39 AM <DIR> .. 2010-04-21 09:39 AM <DIR> locks 2010-04-21 09:39 AM <DIR> hooks 2010-04-21 09:39 AM <DIR> conf 2010-04-21 09:39 AM 229 README.txt 2010-04-21 11:45 AM <DIR> db 2010-04-21 09:39 AM 2 format 2 File(s) 231 bytes After setting up hg and the convert extension and attempting the convert, I get the following on convert: C:\>hg convert file://localhost/Users/terry/Desktop/repoSVN assuming destination repoSVN-hg initializing destination repoSVN-hg repository file://localhost/Users/terry/Desktop/repoSVN does not look like a CVS checkout file://localhost/Users/terry/Desktop/repoSVN does not look like a Git repo file://localhost/Users/terry/Desktop/repoSVN does not look like a Subversion repo file://localhost/Users/terry/Desktop/repoSVN is not a local Mercurial repo file://localhost/Users/terry/Desktop/repoSVN does not look like a darcs repo file://localhost/Users/terry/Desktop/repoSVN does not look like a monotone repo file://localhost/Users/terry/Desktop/repoSVN does not look like a GNU Arch repo file://localhost/Users/terry/Desktop/repoSVN does not look like a Bazaar repo file://localhost/Users/terry/Desktop/repoSVN does not look like a P4 repo abort: file://localhost/Users/terry/Desktop/repoSVN: missing or unsupported repository I have TortoiseHg installed. For info, hg version reports: Mercurial Distributed SCM (version 1.4.3) This version of Mercurial seems to have some svn bindings if library.zip in the install is to be believed. Do I need to do a checkout and point hg convert to it for this to work properly?
