  • What naming conventions exist for the primary Node.js file?

    - by Tom Dworzanski
    This question has been completely edited in hopes that it will be reopened. The naming of the main Node.js file is something left to the user and and does not seem to be defined by any well established convention. In hopes of finding a good name, I am curious if there are naming conventions in other parts of the Node.js ecosystem that might suggest a name to use. Some names I have seen are: app.js, index.js, main.js, server.js, etc. Please provide only well documented standards in answers.

  • node.js storing gamestate, how?

    - by expressnoob
    I'm writing a game in javascript, and to prevent cheating, i'm having the game be played on the server (it's a board game like a more complicated checkers). Since the game is fairly complex, I need to store the gamestate in order to validate client actions. Is it possible to store the gamestate in memory? Is that smart? Should I do that? If so, how? I don't know how that would work. I can also store in redis. And that sort of thing is pretty familiar to me and requires no explanation. But if I do store in redis, the problem is that on every single move, the game would need to get the data from redis and interpret and parse that data in order to recreate the gamestate from scratch. But since moves happen very frequently this seems very stupid to me. What should I do?

  • Getting req.params in order in Express JS

    - by Adam Terlson
    In Express, is there a way to get the arguments passed from the matching route in the order they are defined in the route? I want to be able to apply all the params from the route to another function. The catch is that those parameters are not known up front, so I cannot refer to each parameter by name explicitly. app.get(':first/:second/:third', function (req) { output.apply(this, req.mysteryOrderedArrayOfParams); // Does this exist? }); function output() { for(var i = 0; i < arguments.length; i++) { console.log(arguments[i]); } } Call on GET: "/foo/bar/baz" Desired Output (in this order): foo bar baz

  • Looking for input on GWT / MVP action w/o browser history change

    - by user198313
    Hello there, I am trying to develop a GWT app with the MVP pattern. So far so good except for one specific case of actions: actions that do not change the url (no browser history change). In the GWT MVP pattern, events are sent from presenters, the an app controller catches them and update the browser history. If the history has changed then the view updates. ** MVP with history change (Works well)** Current URL is /list User clicks on contactdelete button. Fire DeleteContactAction event. App controller catches, change history to 'delete' onValueChange is called if (token.equals("delete")) delete contact screen, then delete contact Fire ContactDeletedEvent app controller catches and change the history to list onValueChange is called: contact list refreshes GWT MVP pattern for dialog box w/o history changes ** Issue ** - I use a dialog box and I don't want to change the browser history, so here is the problem: Current URL is /list User clicks on contactdelete button. Contact is deleted Fire ContactDeletedEvent. App controller catches, change history to 'list' **onValueChange is NOT called** because url is already /list and there is no change # problem: contact list does not refresh Question: does anyone know a pattern to implement this in the context of MVP? Any help / idea appreciated.

  • Directory structure for a website (js/css/img folders)

    - by nightcoder
    For years I've been using the following directory structure for my websites: <root> ->js ->jquery.js ->tooltip.js ->someplugin.js ->css ->styles.css ->someplugin.css ->images -> all website images... it seemed perfectly fine to me until I began to use different 3rd-party components. For example, today I've downloaded a datetime picker javascript component that looks for its images in the same directory where its css file is located (css file contains urls like "url('calendar.png')"). So now I have 3 options: 1) put datepicker.css into my css directory and put its images along. I don't really like this option because I will have both css and image files inside the css directory and it is weird. Also I might meet files from different components with the same name, such as 2 different components, which link to background.png from their css files. I will have to fix those name collisions (by renaming one of the files and editing the corresponding file that contains the link). 2) put datepicker.css into my css directory, put its images into the images directory and edit datepicker.css to look for the images in the images directory. This option is ok but I have to spend some time to edit 3rd-party components to fit them to my site structure. Again, name collisions may occur here (as described in the previous option) and I will have to fix them. 3) put datepicker.js, datepicker.css and its images into a separate directory, let's say /3rdParty/datepicker/ and place the files as it was intended by the author (i.e., for example, /3rdParty/datepicker/css/datepicker.css, /3rdParty/datepicker/css/something.png, etc.). Now I begin to think that this option is the most correct. Experienced web developers, what do you recommend?

  • My History with Agile

    - by Robert May
    I’m going to write my history with Agile here.  That way, in future posts, I can refer back to it, instead of typing it out in the post that contains information you may actually want to read.  Note that I’m actually a pretty senior developer, and do lots of technical interviews.  I’m an Agile fan because of the difference it makes in peoples lives and the improvement in quality it brings, and I’ll sacrifice my technological advance to help teams. Management History I started management pretty early in my career, starting with the first job that I ever had.  I actually do NOT have a CS or similar degree.  I have a Bachelor’s of Business Administration with an emphasis in Computer Information Systems. My first management gigs were around call center work and were very schedule oriented.  I didn’t understand the true value of teams, and I’m ashamed to admit, I actually installed a fingerprint scanner as a time clock in this job.  I shudder to think of the impact that I had on the team spirit.  I didn’t even trust them enough to fill out their time cards correctly.  How sad. I was managing nearly 100 people in this position, with the help of a great set of subordinates. I did try to come up with reward programs for the team, but again, didn’t understand the concept of team, so instead of letting the team determine how the rewards should work, I mandated from on high, which isn’t a good thing. I was told that I wasn’t the type that would be a good manager by people whom I respected a lot.  They said it because I was a computer geek, since they don’t understand good management either, but in retrospect, they were right about me then.  I was too green. After my first job, I went on to other jobs and with the exception of one job, I’ve managed people at them all.  The rest of the management story is important for understanding agile, so I’ll save it for my next post. Technical History I’ve been in software development for many, many years.  I technically started programming on a commodore 64 in basic.  I didn’t know that I was programming, but I was sure having fun.  That was followed by batch files, Gorilla hacking (I always had to win), WordPerfect Macro programming and other things that taught me the basics. My first “real” job was with a telephone company, and that’s where I made my first database application in DataEase, wrote my first VBA app and started using real programming tools, like turbo pascal, vb3-vb5, and semi-real tools like RPG and VisualRPG.  I wrote my first web page in 1994, and built my first data driven web page in 1995 using perlDB.  You really can do anything with Perl.  At this time, I also started a Linux based internet service provider that is still in operation today.  One of the people I worked with is now a Microsoft employee building and designing frameworks you probably know well.  Smart guy.  I also built my first ASP applications connecting to Sql Server 6.5, setup Exchange 5.5 for the company, and many other system administration stuff.  I’m a programmer by choice, mostly because I don’t really like PC support. From there, I went on to a large state agency.  I got to see and maintain true waterfall projects.  5 years of maintaining the 200 VB COM+ (MTS, actually) dlls that were used to calculate a single number is a long time.  That was all Microsoft DNS technologies.  SQL Server and VB6 were the tools of choice, although .net started to be a factor near the end of employment.  I did some heavy XML work at this job and even wrote an XSD parser and validator in VB6 that was a shim until MSXML 3.0 came out.  Prior to 3.0, XSD’s weren’t supported, and I didn’t want to write DTDs. Ironically, jobs after this were more generic.  I pretty much settled in on the .net framework and revisions of it.  Lots of WPF, some silverlight, lots of ASP.NET, some SQL Azure, lots of SQL Server, some Oracle, but I don’t think that I was as passionate about development and technologies.  I was more into the management of development.  I like people.

  • JS and CSS caching issue: possibly .htaccess related

    - by adamturtle
    I've been using the HTML5 Boilerplate for some web projects for a while now and have noticed the following issue cropping up on some sites. My CSS and JS files, when loaded by the browser, are being renamed to things like: ce.52b8fd529e8142bdb6c4f9e7f55aaec0.modernizr-1,o7,omin,l.js …in the case of modernizr-1.7.min.js The pattern always seems to add ce. or cc. in front of the filename. I'm not sure what's causing this, and it's frustrating since when I make updates to those files, the same old cached file is being loaded. I have to explicitly call modernizr-1.7.min.js?v=2 or something similar to get it to re-cache. I'd like to scrap it altogether but it still happens even when .htaccess is empty. Any ideas? Is anyone else experiencing this issue?

  • How to stop Bash appending history

    - by Craig
    I am having a lot of trouble setting up the terminal history of Bash the way I want. I would like to have no duplicate entries and if I enter a command I want it saved and the duplicates above removed. The problem is the history command shows me it is functioning the way I want however once I log out the duplicates come back again. I believe it is just appending the history to the existing one. I have these lines in my .bashrc file (~/.bashrc) HISTCONTROL=ignoreboth:erasedups shopt -u histappend I have even tried uncommenting shopt but it still appends the history on logout. How can I have the history be exactly how it is before I logout?

  • new project; entire node.js app

    - by Jared
    I have been looking into Node.js, express and Nowjs and love how easy it is to have real time interactions between clients. My background is mostly from CodeIgniter MVC using PHP and MYSql. I want to re make a current web project of mine from scratch to make everything better and more real time with this newer technology. After researching and doing test examples I want to use node.js , express and Nowjs for the real time interactions once someone connects to the socket.io to pull data back to clients. But use Code Igniter for the control of the site and user management , possible shopping cart/store , pretty much everything else. This is purely due to time constraints and that I am already familiar with doing it that way. I have been looking at MongoDB as an alternative to MySql, Basically the app is going to be multiple chat rooms all on one page. with the ability of notifications and private messaging. Lots of data transfer and images. before I started piecing it together I wanted to get people who have already done something similar. My model would use Code Igniter and MySQL to render the page and then connect them onto a node.js server and broadcast using express and nowjs would using a mongoDB be better than mySQL for tons of messages and data being stored or MYSQL? Also does it make since to not make the whole site on Node.js , kinda piece it together like that? I was asked to re post this somewhere else as it was not up to the format for SO, OP from here http://stackoverflow.com/questions/12649469/new-project-need-some-start-up-advice-node-js-app#comment17062924_12649469

  • Debugging Node.js applications for Windows Azure

    - by cibrax
    In case you are developing a new web application with Node.js for Windows Azure, you might notice there is no easy way to debug the application unless you are developing in an integrated IDE like Cloud9. For those that develop applications locally using a text editor (or WebMatrix) and Windows Azure Powershell for Node.js, it requires some steps not documented anywhere for the moment. I spent a few hours on this the other day I practically got nowhere until I received some help from Tomek and the rest of them. The IISNode version that currently ships with the Windows Azure for Node.js SDK does not support debugging by default, so you need to install the IISNode full version available in the github repository.  Once you have installed the full version, you need to enable debugging for the web application by modifying the web.config file <iisnode debuggingEnabled="true" loggingEnabled="true" devErrorsEnabled="true" /> The xml above needs to be inserted within the existing “<system.webServer/>” section. The last step is to open a WebKit browser (e.g. Chrome) and navigate to the URL where your application is hosted but adding the segment “/debug” to  the end. The full URL to the node.js application must be used, for example, http://localhost:81/myserver.js/debug That should open a new instance of Node inspector on the browser, so you can debug the application from there. Enjoy!!

    Jealous of your Mac OS X friends and their great Time Machine feature? Windows 8 has a new feature called File History that works much the same way, giving you an easy method to restore previous versions of your files. We are going to use a networked folder in for our article but you could always skip creating the network folder, and just use a USB drive. To use a USB drive you can just go to the setting for File History and turn it on, it should automatically find your USB and immediately start working.

  • SEO and JavaScript since Google admits JS parsing

    - by schlingel
    We're planning on building a HTML snapshot creation service to provide the Google crawlers with static HTML of our JS driven single page application. Is this still necessary and/or encouraged since Google openly admits it is parsing JS now? How should I tackle this evaluation? Are there tools to provide data on when it's needed to provide snapshots and when google has sufficent parsing? Is it better because it would be much faster in comparison to the JS incremental rendering?

  • How does Google Chrome know my Firefox history if I never imported it?

    - by fdisk
    I have Firefox and Google Chrome installed in the same machine (Linux). It happens when I type something in Chrome Omnibox it suggests pages I have already visited in Firefox. I have never connected the accounts of both browsers I have never imported information from one browser to other I have never visited the suggested pages in Chrome The keyword I type in the omnibox is vague and there is no way it could guess the suggestion without having access to the Firefox history. i.e.: i type "ir" in Chrome and it suggests me the same Iron Maiden lyrics page I have browse before in Firefox.

  • In GNU Screen, Recalled bash history command displays one character position to the left of actual location

    - by vergueishon
    I am running Red Hat 5 32-bit (2.6.18-194.26.1.el5). The issue is that when I recall any previous command in bash's history, the first character in the command is displayed immediately after the shell prompt, without any intervening space, likeso: \[me@mymachine tmp]$man mysql If I enter a Ctrl-C, and retype the command, it looks likeso: \[me@mymachine tmp]$ man mysql This makes recalling a command and editing it before re-entering a real pain. Basically, if I try to edit a recalled command, my changes occur one character position to the left (I believe) of what I see on the screen. It's a bit tedious to describe, and appears to only happen with commands with a large number of arguments. UPDATE: The contents of /etc/sysconfig/bash-prompt-screen, 1 #!/bin/bash 2 echo -n $'\033'"_${USER}@${HOSTNAME%%.*}:${PWD/#$HOME/~}"$'\033\\\\' and the contents of /etc/bashrc, 24 screen) 25 if [ -e /etc/sysconfig/bash-prompt-screen ]; then 26 PROMPT_COMMAND=/etc/sysconfig/bash-prompt-screen 27 else 28 PROMPT_COMMAND='echo -ne "\033_${USER}@${HOSTNAME%%.*}:${PWD/#$HOME/~}"; echo -ne "\033\\"' 29 fi 30 ;; I've disable bash-prompt-screen by renaming it--this fixed it. It's entirely possible that there is a fix to the bash-prompt-screen prompt line in the latest version of screen for RHEL 5. The error is seen under Screen version 4.00.03 (FAU) 23-Oct-06. (I noticed an update in the queue, which is installing as I write this.)

  • Firefox: Clear History Is SUPER EFFECTIVE?

    - by acidzombie24
    I'm seeing a performance problem on certain sites (like gmail) which clearing the history should not affect. Is this a website problem or a firefox problem and what can i do to fix it w/o clearing my history? Also as a webdeveloper i am interested in how to make this happen (or not happen). I'm using firefox 8 and i confirmed the problem by copying my profile to firefox 11 (portable). To reproduce go to gmail.com and sign in. Have your task manager open. Once you click signin or hit enter gmail will bring up your emails. Keep your eye on the CPU usage. I checked and right now on this machine its using all my CPU for 22seconds!!!! Yes. 22 seconds. Once i cleared my "browser & download history" Its <6seconds. WTF. I have no idea why or how the size of history and CPU usage when loading up gmail are correlated. I have firefox setup so it never clears the history. But... 22seconds is a disaster. Can someone explain why this is happening or a fix that isnt clearing my history? I tried visiting a few websites and only gmail eats up that much CPU. Most websites only take <5sec of max CPU. So maybe this is a gmail problem? Or a firefox problem that gmail happens to hit? I still dont understand why it happens. -edit- I forgot to mention places.sqlite is 90mb. I dont think that matters. I have a sqlite file 400mb which is pretty much 2 large tables. It has no performance issues
