  • What resources do you recommend for learning more about TCP/IP, networking, and related areas?

    - by mkelley33
    As a relatively-new Python programmer, I'm finding more and more that networking as it relates to the web and web development is becoming increasingly important to understand. When I was an active C# ASP.NET programmer making smaller websites with less responsibility this knowledge seemed less important, since there was often a "networking" guy performing any tasks beyond acquiring a domain name for a client. Which books, websites, presentations, articles, or other resources would you recommend so that I best understand what's happening between the time a user types a URL and receives the rendered HTML? Thanks!

  • How to create selectable themes in your ASP.Net applications

    - by nikolaosk
    In this post I am going to show you something that we see in most websites. When we visit a website we are given the choice through a control to select the theme(colors,font size,font family) that we want to be applied to the site. In almost all asp.net web sites we define the look and feel of the site through Themes , skins , Master Pages and Stylesheets . I assume that you know a little bit about CSS,XHTML. I assume that you have little knowledge of web forms and master pages. Before you go on...(read more)

  • Worthwhile to upgrade my Ruby Pickaxe book?

    - by ewindisch
    I have Programming Ruby, The Pragmatic Programmers' Guide, Second Edition which covers Ruby 1.8. It has been several years since I have programmed in Ruby, but I'd like to refresh my memory and bring my knowledge current. With most programming languages, I've found that I can skip books that only concern a single version bump. Yet, Ruby is a young language and I understand there may have been significant changes in 1.9. Although I already have the second edition, is it worthwhile to buy the third edition for Ruby 1.9? Are the differences that vast, or will it be simple enough to catch up to 1.9 with the online docs?

  • "Oracle Certified Expert, Java Platform, Enterprise Edition 6 Java Persistence API Developer" Preparation

    - by Matt
    I have been working with Hibernate for a fews years now, and I want to solidify and demonstrate my knowledge by taking the Oracle JPA certification, also known as: "Oracle Certified Expert, Java Platform, Enterprise Edition 6 Java Persistence API Developer (CX-310-094)" There is a training course provided by Oracle: "Building Database Driven Applications with JPA (SL-370-EE6)" But this costs $1800 and I think it would be overkill for my needs. Ideally, I would like a self study guide that will cover everything in the exam. I have looked for books and these seem like possibilities: Pro JPA 2: Mastering the Java Persistence API (Expert's Voice in Java Technology) and Beginning Java EE 6 with GlassFish 3 2nd Edition (Expert's Voice in Java Technology) But these aren't checklist type study guides as far as I am aware. I found the official SCJP study guide very useful, but I think the equivalent text for the JPA exam isn't out yet. If anyone has taken this exam, I would be grateful to hear how you prepared for it. Thanks!

  • Is the C programming language still used?

    - by Pankaj Upadhyay
    I am a C# programmer, and most of my development is for websites along with a few Windows application. As far as C goes, I haven't used it in a long time, as there was no need to. It came to me as a surprise when one of my friends said that she needs to learn C for testing jobs, while I was helping her learn C#. I figured that someone would only learn C for testing only if there is development done in C. In my knowledge, all the development related to COM and hardware design are also done in C++. Therefore, learning C doesn't make sense if you need to use C++. I also don't believe in historic significance, so why waste time and money in learning C? Is C is still used in any kind of new software development or anything else?

  • CSS just for most basic HTML

    - by Gerenuk
    I've read that my note system Wikidpad, which exports to very simple HTML, can use CSS (http://wikidpad.sourceforge.net/help/HtmlCss.html) The elements in the output are not more than basic headings, bullet points and tables. I'd like to try some kind of improved style, but I as I have no knowledge about CSS, so the best I can do is to save some Myfile.css to a directory :) However if I google "CSS template" I get all sorts of complicating results that I cannot make sense of :( Am I using wrong terminology? Can you suggest what I should search for or maybe you even know a ressource where a get a simple CSS file with some decent standard HTML elements. I do not wish to make custom adjustments.

  • Topics for development team cross training sessions

    - by BBlake
    Our team of developers are going to start holding monthly meetings for the purposes of cross training and knowledge improvement. We're looking for ideas for topics to discuss. We've already made a list of some obvious ones, such as discussions/training on specific applications, proper usage of TFS for source control, bug tracking and code reviews, coding standards, and corporate architecture. The problem we're having is that we are a cross-platform development team so we don't want to look at topics that only apply to certain members of the team (Sql, .NET, reporting, third party apps, etc). We'll use sub-team meetings for those. So what other topics that would apply across a broad development team would be good for these training sessions?

  • Rich Snippets - LocalBusiness - Photos - Correct Implementation

    - by user32622
    Does somebody know, how this is supposed to be implemented correctly? In my local business full page, I have a carousel with several images, so what I did is that on the container of this carousel i have written the following: "itemprop='photos' itemscope itemtype="http://schema.org/ImageObject"", i.e. <div class="tourism-product-media-gallery" itemprop='photos' itemscope itemtype="http://schema.org/ImageObject"> and then on each and every image i have written the following: "itemprop="contentURL"", i.e. <img src="@mediaItem.NormalImage" alt="@mediaItemCaption" itemprop="contentURL"/> But i am not convinced that this is the way it should be. Anyone has any insight on this and more knowledge? Thanks Note: here are the results from the rich snippet google testing tool: click here

    - by Jalpesh P. Vadgama
    Few days back I was optimizing the performance with Entity framework and Linq queries and I was using LinqPad and looking SQL generated by the Linq or entity framework queries.

So in this post I will explain how to find SQL statements generated Entity framework queries. Read More on dotnetjalps.com

  • Choosing a CSS grid/framework

    - by jonallard
    There are many grids and framework to choose from. A Google search for CSS frameworks will return a dozen articles that themselves list a number of frameworks to choose from. When it comes to choosing one, it's easy to be lost without having an intimate knowledge of all of them. What are the main factors that go into choosing a CSS framework, and how will those choices map to certain frameworks? More generally, how does one choose a CSS framework? Note 1: I'm using "grid" and "framework" almost interchangeably here, but there is probably one I should use over the other. Corrections on this are welcome. Note 2: I am well aware that some choices will depend on taste and accordingly, this question can turn into a "best of" contest/subjective topic. I'm trying to keep it as answerable as possible, as I'm pretty sure many have this problem/question of choosing a framework and an answer to that would benefit the community. As such, improvements to this question are welcome rather than just closing it.

  • How do I learn Python from zero to web development? [closed]

    - by Terence Ponce
    I am looking into learning Python for web development. Assuming I already have some basic web development experience with Java (JSP/Servlets), I'm already familiar with web design (HTML, CSS, JS), basic programming concepts and that I am completely new to Python, how do I go about learning Python in a structured manner that will eventually lead me to web development with Python and Django? I'm not in a hurry to make web applications in Python so I really want to learn it thoroughly so as not to leave any gaps in my knowledge of the technologies involving web development in Python. Are there any books, resource or techniques to help me in my endeavor? In what order should I do/read them? UPDATE: When I say learning in a structured manner, I mean starting out from the basics then learning the advanced stuff without leaving some of the important details/features that Python has to offer. I want to know how to apply the things that I already know in programming to Python.

  • Can you be a web and desktop developer at the same time?

    - by Charmop
    In my environment, I found web programmers, desktop programmers and both web and desktop programmers. About myself I started my career with desktop development using C and then Java, did couple of simple level projects. Then at the final graduating year, my project was a web one, so I turned to web development until this moment. But, when I meet people having chosen to be web or software developers from the beginning, I figure out that they have more knowledge/experience than I have. So I get kind of regret why didn't I specialize my self from the first day? The question is: Is it a good habit to work at two, more or less, different fields: web and desktop? Or we must specialize ourselves?

  • How would you explain that software engineering is more specialized than other engineering fields?

    - by Spencer K
    I work with someone who insists that any good software engineer can develop in any software technology, and experience in a particular technology doesn't matter to building good software. His analogy was that you don't have to have knowledge of the product being built to know how to build an assembly line that manufactures said product. In a way it's a compliment to be viewed with an eye such that "if you're good, you're good at everything", but in a way it also trivializes the profession, as in "Codemonkey, go sling code". Without experience in certain software frameworks, you can get in trouble fast, and that's important. I tried explaining this, but he didn't buy it. Any different views or thoughts on this to help explain that my experience in one thing, doesn't translate to all things?

  • Doing "it all from scratch" is different than OS-specifics

    - by Bigyellow Bastion
    Many people tell me that in order to write my own operating system I need to understand the inner-workings of the one I'll be writing it on. That's nonsense. I mean I understand it for education purposes, such as studying the workings of a current OS to gain better knowledge of writing one myself. But the OS I'm writing it on is nothing but my scratchpad offering me software to write the code in, and software to assemble/compile my code into executable instructions. I've been told that I need to decide which OS I'm writing it on before I write it, but all I need is an assembler to produce flat binary, or a compiler to produce object code and a linker to link it into a flat binary .bin file. Why do people say it matters which OS you make an OS on, when it doesn't?

    I have a problem when trying to login to my Kubuntu 10.10. The login screen shows up, then I type my password, a blank screen is shown with my desktop background picture and then throws me back on the login screen. if I choose to login from console, I can do that, and by typing startx I can log in just fine but in the end I cannot shutdown the computer from the k menu nor will my settings remembered for the next time I log back. I have my home directory mounted from a different partition but I tried to create a new user account and I could log in without any kind of problem. The home directory is not encrypted, at least not to my knowledge. Some log files: Xorg.0.log dmesg.out kdm.log xsession.errors

  • The Oracle Graduate Experience...A Graduates Perspective by Angelie Tierney

    - by david.talamelli
    [Note: Angelie has just recently joined Oracle in Australia in our 2011 Graduate Program. Last week I shared my thoughts on our 2011 Graduate Program, this week Angelie took some time to share her thoughts of our Graduate Program. The notes below are Angelie's overview from her experience with us starting with our first contact last year - David Talamelli] How does the 1 year program work? It consists of 3 weeks of training, followed by 2 rotations in 2 different Lines of Business (LoB's). The first rotation goes for 4 months, while your 2nd rotation goes for 7, when you are placed into your final LoB for the program. The interview process: After sorting through the many advertised graduate jobs, submitting so many resumes and studying at the same time, it can all be pretty stressful. Then there is the interview process. David called me on a Sunday afternoon and I spoke to him for about 30 minutes in a mini sort of phone interview. I was worried that working at Oracle would require extensive technical experience, but David stressed that even the less technical, and more business-minded person could, and did, work at Oracle. I was then asked if I would like to attend a group interview in the next weeks, to which I said of course! The first interview was a day long, consisting of a brief introduction, a group interview where we worked on a business plan with a group of other potential graduates and were marked by 3 Oracle employees, on our ability to work together and presentation. After lunch, we then had a short individual interview each, and that was the end of the first round. I received a call a few weeks later, and was asked to come into a second interview, at which I also jumped at the opportunity. This was an interview based purely on your individual abilities and would help to determine which Line of Business you would go to, should you land a graduate position. So how did I cope throughout the interview stages? I believe the best tool to prepare for the interview, was to research Oracle and its culture and to see if I thought I could fit into that. I personally found out about Oracle, its partners as well as competitors and along the way, even found out about their part (or Larry Ellison's specifically) in the Iron Man 2 movie. Armed with some Oracle information and lots of enthusiasm, I approached the Oracle Graduate Interview process. Why did I apply for an Oracle graduate position? I studied a Bachelor of Business/Bachelor of Science in IT, and wanted to be able to use both my degrees, while have the ability to work internationally in the future. Coming straight from university, I wasn't sure exactly what I wanted to do in terms of my career. With the program, you are rotated across various lines of business, to not only expose you to different parts of the business, but to also help you to figure out what you want to achieve out of your career. As a result, I thought Oracle was the perfect fit. So what can an Oracle ANZ Graduate expect? First things first, you can expect to line up for your visitor pass. Really. Next you enter a room full of unknown faces, graduates just like you, and then you realise you're in this with 18 other people, going through the same thing as you. 3 weeks later you leave with many memories, colleagues you can call your friends, and a video of your presentation. Vanessa, the Graduate Manager, will also take lots of photos and keep you (well) fed. Well that's not all you leave with, you are also equipped with a wealth of knowledge and contacts within Oracle, both that will help you throughout your career there. What training is involved? We started our Oracle experience with 3 weeks of training, consisting of employee orientation, extensive product training, presentations on the various lines of business (LoB's), followed by sales and presentation training. While there was potential for an information overload, maybe even death by Powerpoint, we were able to have access to the presentations for future reference, which was very helpful. This period also allowed us to start networking, not only with the graduates, but with the managers who presented to us, as well as through the monthly chinwag, HR celebrations and even with the sharing of tea facilities. We also had a team bonding day when we recorded a "commercial" within groups, and learned how to play an Irish drum. Overall, the training period helped us to learn about Oracle, as well as ourselves, and to prepare us for our transition into our rotations. Where to now? I'm now into my 2nd week of my first graduate rotation. It has been exciting to finally get out into the work environment and utilise that knowledge we gained from training. My manager has been a great mentor, extremely knowledgeable, and it has been good being able to participate in meetings, conference calls and make a contribution towards the business. And while we aren't necessarily working directly with the other graduates, they are still reachable via email, Pidgin and lunch and they are important as a resource and support, after all, they are going through a similar experience to you. While it is only the beginning, there is a lot more to learn and a lot more to experience along the way, especially because, as we learned during training, at Oracle, the only constant is change.

  • Techniques to read code written by others?

    - by Simon
    Are there any techniques that you find useful or follow when it comes to reading and understanding code written by others when Direct Knowledge Transfer/meeting the person who wrote the code is not an option. One of the techniques that I follow when dealing with legacy code is by adding additional debugging statements and based on the values I figure out the flow/logic. This can be tedious at times. Hence the reason behind this question, Are there any other techniques being widely practiced or that you personally follow when it comes to dealing with code written by other people/colleagues/open-source team?
