  • Type of computer for a developer on the road

    - by nabucosound
    Hi developers: I am planning to be traveling through eurasia and asia (russia, china, korea, japan, south east asia...) for a while and, although there are plenty of marvelous things to see and to do, I must keep on working :(. I am a python developer, dedicated mainly to web projects. I use django, sqlite3, browsers, and ocassionaly (only if I have no choice) I install postgres, mysql, apache or any other servers commonly used in the internets. I do my coding on vim, use ssh to connect, lftp to transfer files, IRC, grep/ack... So I spend most of my time in the terminal shells. But I also use IM or Skype to communicate with my clients and peers, as well as some other software (that after all is not mandatory for my day-to-day work). I currently work with a Macbook Pro (3 years old now) and so far I am very happy with the performance. But I don't want to carry it if I am going to be "on transit" for long time, it is simply huge and heavy for what I am planning to load in my rather small backpack (while traveling, less is more, you know). So here I am reading all kind of opinions about netbooks, because at first sight this is the kind of computer I thought I had to choose. I am going to use Linux for it, Microsoft is not my cup of tea and Mac is not available for them, unless I were to buy a Macbook air, something that I won't do because if I am robbed or rain/dust/truck loaders break it I would burst in tears. I am concerned about wifi performance and connectivity, I am going to use one of those linux distros/tools to hack/test on "open" networks (if you know what I mean) in case I am not in a place with real free wifi access and I find myself in an emergency. CPU speed should be acceptable, but since I don't plan to run Photoshop or expensive IDEs, I guess most of the time I won't be overloading the machine. Apart from this, maybe (surely) I am missing other features to consider. With that said (sorry about the length) here it comes my question, raised from a deep ignorance regarding the wars betweeb betbooks vs notebooks (I assume tablet PCs are not for programming yet): If I buy a netbook will I have to throw it away after 1 month on the road and buy a notebook? Or will I be OK? Thanks! Hector Update I have received great feedback so far! I would like to insist on the fact that I will be traveling through many different countries and scenarios. I am sure that while in Japan I will be more than fine with anything related to technology, connectivity, etc. But consider that I will be, for example, on a train through Russia (transsiberian) and will cross Mongolia as well. I will stay in friends' places sometimes, but most of the time I will have to work from hostel rooms, trains, buses, beaches (hey this last one doesn't sound too bad hehe!). I think some of your answers guys seem to focus on the geek part but loose the point of this "on the road" fact. I am very aware and agree that netbooks suck compared to notebooks, but what I am trying to do here is to find a balance and discover your experiences with netbooks to see first hand if a netbook will be a fail in the mid-long term of the trip for my purposes. So I have resumed the main concepts expressed here on this small list, in no particular order: keyboard/touchpad feel: I use vim so no need of moving mouse pointers that much, unless I am browsing the web, but intensive use of keyboard screen real state: again, terminal work for most of the time battery life: I think something very important weight/size: also very important looks not worth stealing it, don't give a shit if it is lost/stolen/broken: this may depend on kind of person, your economy, etc. Also to prevent losing work, I will upload EVERYTHING to the cloud whenever I'll have a chance. wifi: don't want to discover my wifi is one of those that cannot deal with half the routers on this planet or has poor connectivity. Thanks again for your answers and comments!

  • Construction Paper, Legos, and Architectural Modeling

    I can remember as a kid playing with construction paper and Legos to explore my imagination. Through my exploration I was able to build airplanes, footballs, guns, and more, out of paper. Additionally I could create entire cities, robots, or anything else I could image out of Legos.  These toys, I now realize were in fact tools that gave me an opportunity to explore my ideas in the physical world through the use of modeling.  My imagination was allowed to run wild as I, unknowingly at the time, made design decisions that directly affected the models I was building from the raw materials.  To prove my point further, I can remember building a paper airplane that seemed to go nowhere when I tried to throw it. So I decided to attach a paper clip to the plane before I decided to throw it the next time to test my concept that by adding more weight to the plane that it would fly better and for longer distances. The paper airplane allowed me to model my design decision through the use of creating an artifact in that I created a paper airplane that was carrying extra weight through the incorporation of the paper clip in to the design. Also, I remember using Legos to build all sorts of creations, and these creations became artifacts of my imagination. As I further and further defined my Lego creations through the process of playing I was able to create elaborate artifacts of my imagination. These artifacts represented design decision I had made in the evolution of my creation through my child like design process. In some form or fashion the artifacts I created as a kid are very similar to the artifacts that I create when I model a software architectural concept or a software design in that the process of making decisions is directly translated in to a tangible model in the form of an architectural model. Architectural models have been defined as artifacts that depict design decisions of a system’s architecture.  The act of creating architectural models is the act of architectural modeling. Furthermore, architectural modeling is the process of creating a physical model based architectural concepts and documenting these design decisions. In the process of creating models, the standard notation used is Architectural modeling notation. This notation is the primary method of capturing the essence of design decisions regarding architecture.  Modeling notations can vary based on the need and intent of a project; typically they range from natural language to a diagram based notation. Currently, Unified Markup Language (UML) is the industry standard in terms of architectural modeling notation  because allows for architectures to be defined through a series of boxes, lines, arrows and other basic symbols that encapsulate design designs in to virtual components, connectors, configurations and interfaces.  Furthermore UML allows for additional break down of models through the use of natural language as to explain each section of the model in plain English. One of the major factors in architectural modeling is to define what is to be modeled. As a basic rule of thumb, I tend to model architecture based on the complexity of systems or sub sub-systems of architecture. Another key factor is the level of detail that is actually needed for a model. For example if I am modeling a system for a CEO to view then the low level details will be omitted. In comparison, if I was modeling a system for another engineer to actually implement I would include as much detailed information as I could to help the engineer implement my design.

  • Right mix of planning and programing on a new project

    - by WarrenFaith
    I am about to start a new project (a game, but thats unimportant). The basic idea is in my head but not all the details. I don't want to start programming without planning, but I am seriously fighting my urge to just do it. I want some planning before to prevent refactoring the whole app just because a new feature I could think of requires it. On the other hand, I don't want to plan multiple months (spare time) and start that because I have some fear that I will lose my motivation in this time. What I am looking for is a way of combining both without one dominating the other. Should I realize the project in the way of scrum? Should I creating user stories and then realize them? Should I work feature driven? (I have some experience in scrum and the classic "specification to code" way.)

  • Why do the GNOME symbolic icons appear darker in a running application?

    - by David Planella
    I'm creating an application that uses symbolic icons from the default theme. However, there are a few icons that I need that cannot be represented by those from the default theme, so I'm creating my own ones. What I did was to simply go to /usr/share/icons/gnome/scalable/actions/, copied a few locally into my app's source tree that could serve as a basis, and started editing them. So far so good. But I've noticed the following: all symbolic icons are of a light grey color when looking at the original .svg file, but when they are put onto a widget, they become darker. Here's an example, using the /usr/share/icons/gnome/scalable/actions/view-refresh-symbolic.svg icon from the default theme: Here's what it looks like when opening the original with Inkscape: And here's what it looks like on a toolbar on a running application: Notice the icon being much darker at runtime. That happens both with the Ambiance and Radiance themes. I wouldn't mind much, but I noticed it affects my custom icon, whereby parts of it become darker (the inner fill), whereas parts of it remain the same color as the original (the stroke). So what causes the default symbolic icons to darken and how should implement that for my custom icons?

    I am just beginning learning Quickly and PyGtk, after see this info-video on Ubuntu-develperment. As in the video I am adding a toolbar to my glade-file, then some buttons.

  • Is obtrusive JavaScript ever ok?

    - by Petah
    I was thinking that if all the users of a website are required to have JavaScript enabled, Is it ok to use obtrusive JavaScript? I'm all for progressive enhancement, but whats the point when an advanced web applications bounces users at the door if they have an old browser or JavaScript disabled? We have a very slim target audience, and we can tell our target audience what browser and plugins/functionality they are required to have. So you my question is, is mixing JS and HTML alright in that case. Like using onclick attributes.

  • Anyone been successful changing their career without having to start over from scratch?

    - by Awaken
    I posted a similar question on careeroverflow, but stackoverflow is just way more active and has way more users, so hopefully someone out there can help answer. I am currently an embedded developer in the defense/aerospace world for a big company. While I like the benefits and the pay, it just isn't keeping me happy. The Paul Graham article: How To Do What You Love really struck home. The problem I face are my golden handcuffs. When I look at jobs out there, they all want 5+ years experience in that language with expertise in framework/tool/server A,B,C, etc... I have worked in C and C++ on the job (in a real-time embedded environment) with some small things in C# and Java. I'm learning Ruby now to expand my knowledge, but I don't consider myself an expert in anything right now. I'd love to work on desktop applications or web apps. Is it possible for someone like me to make the switch without going back to the start line? I'd love to leave the huge bureaucracy and work with some great developers. I'd be willing to work late and take a modest pay cut, but that isn't so clear just from a resume. For those that have altered their career path, how did you do it? For those people who are in charge of hiring, what can I do to help myself?

  • What advantages does developing applications for smartphones have over developing the same application as a web application?

    - by Alfredo O
    Let's take the Facebook application as an example. Why did they develop an application when the users could just access to their page and do the same? For me that represents more maintenance and more cost because for each feature added to the web application that feature will have to be added to the smartphone application as well. So why would I want to develop more than once (for each patform iOS, Android, etc) when I could just have one web application? What benefits do I get? The only one that comes to my mind is GPS feature. EDIT: My question is more oriented towards business applications that are going to be used only by some members of the company, it's not about selling the application (private use). So contrary to what some answers say about that by developing as a smartphone application it will benefit from more sells because of the "smartphone stores" for me this point is not important because the application is for private use. By developing the application as a web application it means that it can be accessed through smartphone browser and also in a PC (any capable browser), but developing as a native application would limit this to only some kind of smartphone so we would be limiting the use. On the other hand developing it as a web application means that in order to access the application an Internet connection must be available. So keeping this in mind how would you convince your boss to write the application for a given smartphone platform (iOS/Android) vs developing it as a web application?

  • What are the most necessary non-language specific things a programmer needs to know?

    - by Josh
    I've been thinking about this a lot lately. Right now I work at a little web company, am almost done with school, and have written an iPhone app, but I'm not sure what else I need to focus my learning energies on. I've decided I want to do software programming, so I've been actively reading everything I can get my hands on that deals with Objective-C / C++ (Cocoa, OpenGL, etc). But those are not the things I'm talking about. I know I need to "master" a language or two. What I'm talking about are the other "things". Things such as learning and using source control, design patterns, etc. What thing (or things, just one per response), would you say I should concurrently be focusing on? You can consider in your answer that I'm wanting to do the aforementioned career path, but you don't have to. I just want a nice list of things to research, and actually use in my career. Also, can someone help me with tagging this? I'm not sure what exactly would be a good tag for such a question.

  • Is it possible to get a job in a high-demand company without having hobby projects?

    - by Rachel
    I was curious if the recruitment team at high-demand companies such as Google takes a lack of hobby projects into consideration when evaluating candidates. I'm a straight 40 hour/week programmer, who is lucky to spend an hour or two a month outside of work on anything programming related. I love hanging out on SO/SE during my breaks at work, and love answering questions, but after work I leave the programming world and go back to my life. I already understand that you don't need hobby projects to be a good programmer, but does this lack of hobby projects affect my chances getting a job at a company that always has a long list of candidates trying to get in?

    I'm developing a diagraming tool and need some metrics to test it against. Unfortunately I couldn't find information regarding an average acceptable FPS level for this kind of web apps. We all know such levels for action games (which is 60fps minimum), 25fps for videostreaming. Can anyone give me some information reagarding minimal FPS level for drawing web apps? What tools would you recomend to test my app?

  • How do you stop yourself from programming?

    - by dan
    Lately I've started earning enough off my software to not have to do consulting to support myself. So I work full time designing and writing my own software products. The problem is that there are no boundaries between my work and my life any more. When I mostly did consulting, I was weary enough of work at the end of the workday to go home and do other things. But now, I sit down to program in the morning, and before I know it it's 11pm and I'm still writing software and not bored or tired at all. I have to force myself to go to sleep. I feel happy and fulfilled, but objectively, I know I need more balance and variety in my life. Any tips or suggestions on how to pull yourself away from the console?

  • Online Poker Game Programng

    - by Eyal
    I am trying to write a massive multiplayer online (mmo) for a poker site, where one user can be on a Flash client and the other on say an iOS client (iPhone / iPad), and would like to know how can interaction between two users be visible on both clients. Do I use MSMQ? AJAX? Other? I need the messaging layer (client interaction messages) to scale up to 100K+ online users to begin with. In other words; What scaleable technology can I use to make game interactions between online users visible to all game participants? Thank you much in advance! Eyal

  • I want to be a programmer, work in corporate environment, earn well, learn fast and eventually become a great programmer [on hold]

    - by Shin San
    I'll try to keep this simple: I'm 29, been dabbling with computers for the past 10 years, had entry level jobs in tech support for different apps, been fixing computers for a while and now want to specialize in something. I'm not 100% stranger to programming but haven't gone past if/then/else with anything. A bit of JavaScript, PHP, Python and currently checking out the "SELECT" statement in SQL :)) I'm curious about programming, I enjoy it and I'm thinking of making a living out of it. So, while I'm at it, why not earn a bit more than the average Joe? So, that's why I'm checking what the best solution, the best learning path and the most useful languages are considering: a) how easy/fast can you find a job by knowing it b) how much would I be able to earn c) how fast can I learn it By reading 10-20 articles online I've come up with an example, but I'm here for some expert advice. Example: * ratings from a) and b) point of view #1 sql ; #2 java ; #3 html (please don't start the markup language debate) ; #4 javascript From this ratings, I'd say a good way to go is learn html/css/(javascript or php) for the web part of apps, some SQL/MySQL/whateverSQL for holding data and loads of Java for the program itself. Please let me know if this is a good idea and if so, what should be the order for learning all of the above. Else, please let me know a better way and why it would be better. Many thanks for taking the time to read my question. Best wishes to you guys Edit: if I think Java + SQL + HTML&JavaScript is the way to go, does the order I'm learning them in matter? Or can I try to learn them all at once?

  • When will microsoft release IE9? [closed]

    - by Rob McKinnon
    I was one of those people early on to try their IE9 beta, and it was terribly buggy. It still does function horribly. IMO any windows release after 5(2k,nt,xp) absolutely sux the life out of my resources compared to RPM linux(opensuse), until at least service pack 2. MS is trying to push HTML5/CSS3 and they cannot pass the Acid 3 test. I am wondering when IE9 will become functional. I am a big supported of MS applications. I have a great amount of adoration for IIS7 because they have support for CGI/PHP. Is IE9 going to be released before 2012?

  • How to market yourself as a software developer?

    - by karlphillip
    I have noticed that this is a frequent issue among younglings from technical areas such as ours. In the beginning of our careers we simply don't know how to sell ourselves to our employers, and random guy #57 (who is a programmer, but not as good as you - technically) ends up getting a raise/promotion just because he knows how to communicate and market himself better than you. Many have probably seen this happen in the past, and most certainly many more will in the future. What kind of skill/ability (either technical, or of other nature) do you think is relevant to point out when doing a job interview or asking for a raise, besides listing all the programming languages and libraries you know?

  • Interfacing the payment systems

    - by etranger
    Hello all. I'm a complete newbie to using online payment systems for web projects, and can't really think of where to start. Let's assume that web system in question needs to generate some income online, and the business idea/functionality is in place, while organizing cash flow is the only unsolved problem. Points of interest are how the custom developed software interfaces to payment systems, and how the resulting income is available to the owner. I do understand that there are probably hundreds of systems out there, but to be more specific on which of them suit, I'd have to know how they work, and that's where I don't feel like understanding much. Thanks in advance.

  • What issues carry the highest risk in a software project?

    - by Mehrdad
    Clearly, software projects are different from other industries in terms of many things like for instance, quality assurance, project progress measurement, and many other things. Unique characteristics of software projects also makes the risk management process unique. Lots of issues in a project might lead it to unacceptable delay or failure to deliver business value. They might even make a complete disaster in the project. What are the deadliest risk factors in a software project? How to analyze, prevent and handle them? Particularly, I'm interested in the issues that you can detect from the beginning and you should keep an eye on (for example, you might be told about a third-party API that the current application uses and lacks documentation). Please share your experiences if they are relevant.

  • Trying to find a recent - PHP book - that utilizes SOLID principles! [closed]

    - by darga33
    Pulling my hair out! I have heard of Martin Fowler's book PoEAA and the other book Head First OOA OOD but those are not in PHP. I desperately want to read them, but ONLY in PHP utilizing the - SOLID acronym - principles! Does anyone know of the absolute best, most recent PHP book that utilizes the SOLID principles and GRASP, and all the other best practices? I want to learn from the best possible source! Not beginner books! I already understand OOP. This seems like an almost impossible question to find the answer to and so I thought, hey, might as well post on stackexchange!! Surely someone out there must know!!!!!!!!!! Or if noone happens to know, Maybe they know of an open source application that utilizes these principles that is relatively small that is not a framework. Something that I can go through every single class, and spend time understanding the insides and outs of how the program was developed. Thanks so much in advance! I really really really really appreciate it! Well it looks like we aren't supposed to ask about best books, so nevermind this question! Sorry about that!

  • Conflict resolution for two-way sync

    - by K.Steff
    How do you manage two-way synchronization between a 'main' database server and many 'secondary' servers, in particular conflict resolution, assuming a connection is not always available? For example, I have an mobile app that uses CoreData as the 'database' on the iOS and I'd like to allow users to edit the contents without Internet connection. In the same time, this information is available on a website the devices will connect to. What do I do if/when the data on the two DB servers is in conflict? (I refer to CoreData as a DB server, though I am aware it is something slightly different.) Are there any general strategies for dealing with this sort of issue? These are the options I can think of: 1. Always use the client-side data as higher-priority 2. Same for server-side 3. Try to resolve conflicts by marking each field's edit timestamp and taking the latest edit Though I'm certain the 3rd option will open room for some devastating data corruption. I'm aware that the CAP theorem concerns this, but I only want eventual consistency, so it doesn't rule it out completely, right? Related question: Best practice patterns for two-way data synchronization. The second answer to this question says it probably can't be done.

  • What is the next promotion for a scrum master

    - by gnebar
    I'm currently a scrum master. I have been offered a promotion to a role that will allow me to have a wider impact. (more involved in company wide architectural decisions, possible secondment to kick start major projects, etc). The role and title of the job has yet to be decided but my company are open to guidance from me. I'm happy I can mould the role to suit me and the company but I'm unsure about the job title that fits this role. Technical Evangelist has been suggested but i'm not sure that is the correct title. I'm keen to proceed down the technical route. What would you suggest? What other roles do people take after scrum master/technical lead? EDIT: (I am aware that my current role is a mix of a technical lead and scrum master role, but that's how we do it in my company :) )
