• 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.

• Managing Personal Projects As Solo Developer - Getting out of depth and failing projects

  - by James Jeffery

  I need some advice on project management. I start a project, and often times it will a large project for a solo developer. Usually its a web project. I handle everything from the UI, to the JS, PHP, server management etc. Half way in I feel out of my depth. I lose where I am, so I spend a couple of days away from the project to avoid the stress and before you know it, it becomes another unfinished project. I try to use frameworks and code libraries to make my developments easier on myself. Sometimes I will complete a project so it "works" and then go back and handle errors, design the UI properly and stuff. But without fail I will always end up out of my depth. I've though about outsourcing tasks such as the UI, and the behaviour, and focusing just on the PHP - which I feel is my strong point. But then pride kicks in, and I don't feel at one with a project I haven't completed myself. Does this make sense? I am sure there are many others who have felt like this either at home, or at work, and I would love some advice on managing my projects better.

• As a solo programmer, of what use can Gerrit be?

  - by s.d

  Disclaimer: I'm aware of the questions How do I review my own code? and What advantages do continuous integration tools offer on a solo project?. I do feel that this question aims at a different set of answers though, as it is about a specific software, and not about general musings about the use of this or that practice or tech stack. I'm a solo programmer for an Eclipse RCP-based project. To be able to control myself and the quality of my software, I'm in the process of setting up a CSI stack. In this, I follow the Eclipse Common Build Infrastructure guidelines, with the exception that I will use Jenkins rather than Hudson. Sticking to these guidelines will hopefully help me in getting used to the Eclipse way of doing things, and I hope to be able to contribute some code to Eclipse in the future. However, CBI includes Gerrit, a code review software. While I think it's really helpful for teams, and I will employ it as soon as the team grows to at least two developers, I'm wondering how I could use it while I'm still solo. Question: Is there a use case for Gerrit that takes into account solo developers? Notes: I can imagine reviewing code myself after a certain amount of time to gain a little distance to it. This does complicate the workflow though, as code will only be built once it's been passed through code review. This might prove to be a "trap" as I might be tempted to quickly push bad code through Gerrit just to get it built. I'm very interested in hearing how other solo devs have made use of Gerrit.

• Vagrant doesn't detect chef-solo unless re-installed

  - by nightowl

  I am using Vagrant to test my Chef recipes in Amazon AWS, and I am encountering an irritating issue: I initially assumed that Vagrant would install chef itself (as it does when using Virtual Box as the provider) but it seems that this needs to be done using the cloud-init script. However, even after I successfully installed the chef gem via cloud-init I was still getting the following error: The chef binary (eitherchef-soloorchef-client) was not found A quick google of this error suggested three probable causes: Chef had failed to install It had installed, but the directory was not in the $PATH environment variable It had installed and in the $PATH but with incorrect permissions I logged in and double checked; chef-solo and chef-client were installed; The path variable for the user, sudo and root all included /usr/local/bin and permissions were all fine. I managed to solve this problem by uninstalling and reinstalling the gem using sudo gem install chef. I don't understand why this should resolve the issue and it is a bit of a problem if I have to ssh into a test box and manually install the gem every time. Does anyone have any suggestions why this might be happening?

• Idiomatic way to invoke chef-solo?

  - by kerkeslager

  What is the idiomatic way to invoke chef-solo? Most sites do this: chef-solo -c ~/solo.rb -j ~/node.json -r http://www.example.com/chef-solo.tar.gz But that's long. There are a few shorter ways to do this that I can think of: A rake task (rake chef-solo). A small shell script (run-chef-solo). An alias (can override the name, like chef-solo). What is the idiomatic way to do this? How are other chef users invoking chef?

• What tools/techniques can benefit a solo developer?

  - by Michael Runyon

  Hello, I am a solo developer, working in a very small web development firm. There is occasional support for development from contractors, but for the most part, if code is written in the office, I am writing it. Many of the articles and such on here talk extensively about the tools and techniques used for collaboration of developers in teams, but that is a non-issue with me, as there is no one to (technically) collaborate with. Yet, I feel that in many ways, there are things that could be adjusted for efficiency. Our small office doesn't participate in many of the meetings/team constructions that most of the techniques rely heavily upon....we mostly just walk around and talk to one another when something is needed. This works great for all of the Just-In-Time, 15 minute fix stuff that probably populates 50% of my day, but I am also constantly working on major projects that require my total concentration, and between a flurry of tiny fixes, and being the primary admin on the 4-6 servers that we own, I find it almost impossible to get real, heavy lifting done. What suggestions can you some of you offer to help me/us become more productive/efficient, without adopting all of the corporate/teamwork practices that we are trying desperately to avoid? At what cost for efficiency is our total relaxation?

• How can a solo programmer become a good team player?

  - by Nick

  I've been programming (obsessively) since I was 12. I am fairly knowledgeable across the spectrum of languages out there, from assembly, to C++, to Javascript, to Haskell, Lisp, and Qi. But all of my projects have been by myself. I got my degree in chemical engineering, not CS or computer engineering, but for the first time this fall I'll be working on a large programming project with other people, and I have no clue how to prepare. I've been using Windows all of my life, but this project is going to be very unix-y, so I purchased a Mac recently in the hopes of familiarizing myself with the environment. I was fortunate to participate in a hackathon with some friends this past year -- both CS majors -- and excitingly enough, we won. But I realized as I worked with them that their workflow was very different from mine. They used Git for version control. I had never used it at the time, but I've since learned all that I can about it. They also used a lot of frameworks and libraries. I had to learn what Rails was pretty much overnight for the hackathon (on the other hand, they didn't know what lexical scoping or closures were). All of our code worked well, but they didn't understand mine, and I didn't understand theirs. I hear references to things that real programmers do on a daily basis -- unit testing, code reviews, but I only have the vaguest sense of what these are. I normally don't have many bugs in my little projects, so I have never needed a bug tracking system or tests for them. And the last thing is that it takes me a long time to understand other people's code. Variable naming conventions (that vary with each new language) are difficult (__mzkwpSomRidicAbbrev), and I find the loose coupling difficult. That's not to say I don't loosely couple things -- I think I'm quite good at it for my own work, but when I download something like the Linux kernel or the Chromium source code to look at it, I spend hours trying to figure out how all of these oddly named directories and files connect. It's a programming sin to reinvent the wheel, but I often find it's just quicker to write up the functionality myself than to spend hours dissecting some library. Obviously, people who do this for a living don't have these problems, and I'll need to get to that point myself. Question: What are some steps that I can take to begin "integrating" with everyone else? Thanks!

• What are the benefits of running chef-server instead of chef-solo?

  - by strife25

  I am looking at automated deployment solutions for my team and have been playing with Chef for the past few days. I've been able to get a simple web app up an running from a base Red Hat VM using chef-solo. Our end goal is to use Chef (or another system) to automatically deploy application topologies to the cloud as we run builds. Our process would basically run like so: Our web app code, dependencies, and chef cookbooks are stored in SCM A build is executed and greats a single package for images to acquire and test against The build engine then deploys new cloud images that run a chef client to get packages installed. The images acquire the cookbooks from SCM or the Chef server and install everything to get up and running What are the benefits and/or use cases for getting a Chef Server running? Are there any major benefits to have a Chef Server hold and acquire the cookbooks from SCM vs. using chef-solo and having a script that will pull the cookbooks from SCM?

• Validar Textbox para aceptar solo n&uacute;meros

  - by Jason Ulloa

  Una de las necesidades más habituales en el desarrollo es poder validar los controles Textbox para que solo acepten valore numéricos. En este post eso es lo que haremos, nos apoyaremos en el lenguaje javascript para validar nuestro textbox del lado del cliente. Nuestro primer paso será crear la función JavaScript que hará el trabajo, para ello agregamos las etiquetas de javascript <script type="text/javascript"> </script> Posteriormente dentro de esas etiquetas agregaremos el script que hará el trabajo function ValidNum(e) { var tecla= document.all ? tecla = e.keyCode : tecla = e.which; return ((tecla > 47 && tecla < 58) || tecla == 46); } Por último iremos al code behind de la página y en el evento Load agregaremos un nuevo evento al textbox para que reconozca el script. protected void Page_Load(object sender, EventArgs e) { TextBox1.Attributes.Add("onkeypress", "javascript:return ValidNum(event);"); } Con esto, tenemos el textbox validado para aceptar solo números y el punto.

• Teamwork 101 for the solo newbie

  - by clankercrusher

  Forgive my newbishness but I have a question to ask about teamwork...mainly because I stink at it. Most of my projects up until this point have been solo so I have a very limited experience with teamwork. I did make graphics for a game that was being developed by several people, but that was completely different than programming with several different people. Right now I'm working with someone else on an indie MMO along with a few other team members. I've already made some pretty stupid mistakes, (like rewriting EVERYTHING) so I have two questions for you guys: 1) What are some of the most common mistakes that people make in a team environment and how can they be avoided? 2) How can the structure of your program be altered to allow for multiple teams members to work on different parts of the program at the same time? P.S. Is this the right stack exchange site for this type of question? (if not, where does it go? Thanks)

• Solo vs Team development and the consequences

  - by Mathieu

  Hi, I've been programming for a while on different languages. I never really studied that at school nor worked on a team of more than 2 (me included). Still, I've been a professional developper for over three years. Last year, I took over my first C# project and it ended up being fine. I can't help but think that because I learned and worked alone I must be missing some concepts/hints/edge. For those who've been solo developpers before being part of a team, can you share your experience? Did you realize you were missing something? Did you find it hard? Did you learn faster after? Thank you!

• Solo .NET Programmer moving to a team

  - by 219558af-62fa-411d-b24c-d08dab

  I've been a solo .NET programmer for a small startup for the last 8 years. I've put together some pretty decent software, and I always strived to better myself and conform to best practices, including source control (SVN/TFS). I worked very closely with a team of engineers of other disciplines, but when it came down to the software I was the only one programming. I love the craft of programming and love learning new things to sharpen my tools. In 2 weeks I will be starting a new job in a team of 20 .NET developers. My position will be mid-level, and I will be working under some programmers with incredibly impressive backgrounds. Again, the team aspect of development will be new to me, so I'm looking for some general "new guy" tips that will help me be as effective and easy to get along with as possible from the get-go. Anything goes, including high level tips, and small day-to-day things about communication. Thanks for any and all input!

• Working Solo On Small Projects: Cowboy Coding The Way To Go?

  - by snicker

  I am a big advocate of agile methods when working on teams and/or large projects. However, I find that for smaller projects, when working solo, I usually start the project writing unit tests, documenting extensively, refactoring. As time wears on, I stop because I feel like I'm wasting time. I find that cowboy coding with an agile spin (testing often, writing human readable code) often works extremely well for me on small, solo projects that I don't expect others to have to work with. Do other people share my sentiment? Or do you think that one should never stick to their guns (get it? cowboys)? So the real question: Are there any agile methodologies that are particularly tailored to a solo project? (other than my "agile cowboy" method above)

• How can I get my progress reviewed as a solo junior developer

  - by Oliver Hyde

  I am currently working for a 2 person company, as the solo primary developer. My boss gets the clients, mocks up some png design templates and hands them over to me. This system has been working fine and i'm really enjoying it. The types of projects I work on are for small - medium sized businesses and they usually want a CMS system. Developed from scratch i'll build a customised backend for the client to add/edit/remove categories, tags, products etc and then output them to the front end according to the design template handed to me. As time has gone on, the projects have increased in complexity, with shopping cart / ordering features and other common e-commerce type features. Again, this system has been working fine and i'm really enjoying it. My issue is my personal development as a programmer. I spend a lot of my spare time reading programming blogs, checking through stackexchange, reading suggested programming books (currently on 'The Pragmatic Programmer', really good so far), doing brain exercises (lumosity.com and khanacademy math problems), doing lots of physical exercise and other personal development type activities. I can't help but feel though, that I'm missing out on feedback, critique. My boss is great and never holds back on praise in regards to my work, but he unfortunately is either to busy to check my code, or to be honest, I don't think it's one of his specialties and so can't provide feedback. I want to know what i'm doing wrong and what i'm doing right. Should I be putting that much logic in the controller, am I modulating my code enough etc. So what I have done is developed a little 'Family Budgeting' app and tried to do it as cleanly and effectively as I currently know how. What i'm wanting to know is, is there somewhere I can submit this app, and have some seasoned developers provide feedback. It's not just a subsection of my code like 'codereview.stackexchange' appears to require, it's my entire workflow that I want critiqued. I know this is a lot to ask, and I expect the main advice given will be to look for a job within a team, which is certainly something I will look into later down the track, but for now I want to persist with my current employment situation, but just don't want to develop too many bad habits. Let me know if I can provide any further information to help clarify, or if this isn't the right place for this type of question I apologise in advance. Didn't want to use reddit as I felt this community fosters more well thought out responses.

• Good Practices for writing large (team/solo) projects (In C)

  - by Moshe Magnes

  Since I started learning C a few years ago, I have never been a part of a team that worked on a project. Im very interested to know what are the best practices for writing large projects in C. One of the things i want to know, is when (not how) do I split my project into different source files. My previous experience is with writing a header-source duo (the functions defined in the header are written in the source). I want to know what are the best practices for splitting a project, and some pointers on important things when writing a project as part of a team.

• What percentage of software developers work solo?

  - by JMather

  I'm trying to put together some ideas for a talk, and one of the things that occurred to me, is if there's any documentation or research into how many programmers work as the lone developer within their team. I think this is an important distinction because individual developers (and perhaps small team developers) end up having to wear many more hats than developers part of a large developer group. It could give us some better insight to career development and transition tactics, as well. I've tried some generally googling, and wasn't able to turn up anything, so I'm hoping maybe someone has seen (or studied) something related to this. Thanks in advance!

• Advantages of BDD for solo developer

  - by user248959

  I have found this lines below about the advantages of BDD (Behavior Driven Development) The domain experts define what they need in the program in a way that the developers can not misinterpret (or at least not as much as in most other approaches). Are there any more advantages apart from that? If I'm working alone (I'm not in contact with managers that could write BDD features), do I need to use BDD?

• Is there an SCM tool made for solo programmers with key logging built in?

  - by pokstad

  Are there any Source Code Management (SCM) tools made specifically for solo programmers or small groups of programmers that tracks every small change made to source code in real time? This would require all key strokes to be tracked, and any other small changes like GUI UI editing. This seems like it would be a very useful tool for a programmer trying to remember a fix he did an hour ago that they didn't manually commit.

• Is my current employer expecting too much?

  - by priyank patel

  This is my first job as a programmer.I am working on ASP.NET/C#,HTML,CSS,Javascript/Jquery. I am working for a firm which develops software for small banking firms. Currently they have their software running in 100 firms.Their software is developed in Visual Fox Pro. I was hired to develop online version of this software.I am the solo developer. My boss is another developer.So my company has two developers. My boss doesnot have any idea about .NET development.I am working on their project since 8 months.The progress is surely there but not very big. I try my best to do what my boss asks.But the project just seems too ambitious for me. The company doesnot have any planning for the project.They just ask me to develop what their older software provides.So I have to deal with front end , back end,review codes , design architecture and etc. I have decided to give my best.I try a lot.But the project sometimes just seems to be overwhelming. So my questions is , is it normal for a programmer to be in this place. I always feel the need to work in atleast a small team if not big one. Are my employers just expecting too much of a fresher.Or is that I being a programmer am lacking the skills to deal with this. I am just not able judge my condition.Also I am paid very low salary.I do work on saturday as well. Can anyone just help me judge this scenario? Any suggestions are welcome.

• How to add URL's to wiki (MediaWiki) powered documentation?

  - by Ian Boyd

  We have an internal company wiki. The wiki engine being used is MediaWiki, the wiki engine that runs Wikipedia. Some of it contains IT stuff. One of the things i want want to have are hyperlinks to the various virtual machines. An example of a command, as it needs to run, is: vmrc://solo.avatopia.com:5901/Windows 2000 Server My first thought was to convert the URL into a link: [vmrc://solo.avatopia.com:5901/Windows 2000 Server] But the content renders literally as above: with the square brackets and all. Testing with other URL protocols: [http://solo.avatopia.com] [ftp://solo.avatopia.com] [ldap://solo.avatopia.com] [vmrc://solo.avatopia.com] Only the first two work, and are converted to hyperlinks. The other two remain as liternal text. How can i add URLs to MediaWiki powered documentation? Original Question We have an internal company wiki.

An example of a command, as it needs to run, is: \\solo\VMRC Client\vmrc.exe solo.avatopia.com:5901/Windows 2000 Server If launching from a command prompt, you have to quote the spaces: C:\>"\\solo\VMRC Client\vmrc.exe" solo.avatopia.com:5901/"Windows 2000 Server" My first thought in converting the above for use on our wiki-site, is to simply HTML-ify it: file://\\solo\VMRC Client\vmrc.exe solo.avatopia.com:5901/&quot;Windows 2000 Server&quot; but MediaWiki only converts file://\solo\VMRC to a hyperlink, the remainder is text. i've tried other random things, including enclosing the URL in square brackets. What is the correct answer? i don't want to happen to randomly stumble on some format that happens to work today, and breaks in the future.

• R and version control for the solo data analyst

  - by Jeromy Anglim

  Many data analysts that I respect use version control. For example: http://github.com/hadley/ See comments on http://permut.wordpress.com/2010/04/21/revision-control-statistics-bleg/ However, I'm evaluating whether adopting a version control system such as git would be worthwhile. A brief overview: I'm a social scientist who uses R to analyse data for research publications. I don't currently produce R packages. My R code for a project typically includes a few thousand lines of code for data input, cleaning, manipulation, analyses, and output generation. Publications are typically written using LaTeX. With regards to version control there are many benefits which I have read about, yet they seem to be less relevant to the solo data analyst. Backup: I have a backup system already in place. Forking and rewinding: I've never felt the need to do this, but I can see how it could be useful (e.g., you are preparing multiple journal articles based on the same dataset; you are preparing a report that is updated monthly, etc) Collaboration: Most of the time I am analysing data myself, thus, I woudln't get the collaboration benefits of version control. There are also several potential costs involved with adopting version control: Time to evaluate and learn a version control system A possible increase in complexity over my current file management system However, I still have the feeling that I'm missing something. General guides on version control seem to be addressed more towards computer scientists than data analysts. Thus, specifically in relation to data analysts in circumstances similar to those listed above: Is version control worth the effort? What are the main pros and cons of adopting version control? What is a good strategy for getting started with version control for data analysis with R (e.g., examples, workflow ideas, software, links to guides)?

• Scrum for a single programmer?

  - by Rob Perkins

  I'm billed as the "Windows Expert" in my very small company, which consists of myself, a mechanical engineer working in a sales and training role, and the company's president, working in a design, development, and support role. My role is equally as general, but primarily I design and implement whatever programming on our product needs to get done in order for our stuff to run on whichever versions of Windows are current. I just finished watching a high-level overview of the Scrum paradigm, given in a webcast. My question is: Is it worth my time to learn more about this approach to product development, given that my development work items are usually given at a very high level, such as "internationalize and localize the product". If it is, how would you suggest adapting Scrum for the use of just one programmer? What tools, cloud-based or otherwise, would be useful to that end? If it is not, what approach would you suggest for a single programmer to organize his efforts from day to day? (Perhaps the question reduces to that simple question.)
