• A programmer who doesn't get to program - where to turn? [closed]

  - by Just an Anon

  I'm in my mid 20's, and have been working as a full time programmer / developer for the last ~6 years, with several years of part-time freelancing before this, and three straight years of freelancing in the middle of this short career. I work mostly with PHP and the Drupal framework. By and large, I focus on programming custom pieces of functionality; these, of course, vary greatly from project to project. I've got years of solid experience with OOP (have done some Java & C# years ago, too) including intensive experience with front-end development, and even some design work. I've lead small teams (2-4 people) of developers. And of course, given the large amount of freelancing, I've got decent project- & client-management skills. My problem is staying motivated at any place of employment. In the time mentioned I've worked (full-time) at six local companies. The longest I've stayed at any company was just over a year. I find that I'll get hired and be very excited and motivated for the first few months, but the work quickly gets "stale." By that I mean that the interesting components (ie. the programming) get done, and the rest of the work turns into boring cleanup (move a button, add text, change colours, add a field). I don't get challenged, and I don't feel like I'm learning anything new. This happens repeatedly time and time again, and I always end up leaving for either a new opportunity, or to freelance. I'm wondering if perhaps I've painted myself into a corner with the rather niche work market (although with very high demand and good compensation) and need to explore other career choices. Another possibility is that I may be choosing the wrong places of employment, mostly small agencies, and need to look into working for a larger, more established firm. I find programming, writing code, and architecting solutions very rewarding. When I'm working on an interesting problem I lose all sense of time and 14-16 hours can fly by like minutes. I get the same exciting feeling when I'm doing high-level planning of a complex system, breaking up the work and figuring out how everything will tie-in together. I absolutely hate doing small, "stupid" changes that pose no challenge, yet seem to make up more and more of my work. I want to find a workplace where I will get to work on such tasks, be challenged, and improve in all areas of product development. This maybe a programming job, management, architecture of desktop apps, or may be managing a taco stand on a beach in Mexico - I don't know, and I need some advice and real-world feedback. What are some job areas worth exploring? The requirements are fairly simple: working with computers interacting with others challenging decent pay (I'm making just short of 90k / year with a month of vacation & some benefits, and would like to stay in this range, but am willing to take a temporary cut in pay for a more interesting position) Any advice would be much appreciated!

• Obtaining MFC Feature Pack GUI elements in .NET WinForms

  - by Cody Gray

  The MFC Feature Pack (and VS 2010) adds out-of-the-box support for several "modern" GUI elements (such as MDI with tabbed documents, the ribbon, and a Visual Studio-style interface with docking panels). These are a boon to those of us that have to support legacy MFC-based applications and want to update their look-and-feel, and a sign that Microsoft has not completely abandoned unmanaged C++ development. However, with the push so strongly in favor of .NET, WinForms, and managed code (and for plenty of good reasons), there seems little reason to develop new applications in unmanaged C++/MFC. The question then becomes how does one obtain these GUI elements in a WinForms application. Almost all of the add-ons and libraries I have found so far cost money, and introduce additional dependencies. I don't have a budget to buy third-party libraries, and the controls provided by Microsoft in MFC for free seem sufficient for our needs. But I still have reservations about learning MFC to develop a new application. Not only does the investment in time seem significant (by all accounts, MFC seems particularly difficult to learn, even for experienced .NET developers--although I am willing to try), but the question of MFC's lifespan is raised as well. Certainly, given the millions of lines of code and existing apps written in native C++, it will be around for some time, but the handwriting seems to be on the wall, so to speak, that it's no longer Microsoft's touted development platform. It seems like these features should be available by now in WinForms without the need for third-party add-ons, or devoting a lot of time and resources to custom-drawing EVERYTHING. Am I just missing something? I find very little online that compares these new features of MFC to what is available in WinForms, mainly because most everything written on MFC pre-dated its most recent update, before which it looked admitted "dated," and with its other flaws, was hardly an appealing platform for new development. With the very recent release of VS 2010, we have a while to wait before WinForms gets updated again. What routes are you guys taking for applications whose customers demand a modern-looking UI on a budget?

• WPF: How to set column width with auto fill in ListView with custom user control.

  - by powerk

  A ListView with Datatemplate in GridViewColumn: <ListView Name ="LogDataList" IsSynchronizedWithCurrentItem="True" ItemsSource="{Binding LogDataCollection}" Background="Cyan"> <ListView.View> <GridView AllowsColumnReorder="true" ColumnHeaderToolTip="Event Log Information"> <GridViewColumn Header="Event Log Name" Width="100"> <GridViewColumn.CellTemplate> <DataTemplate> <l:MyTextBlock Height="25" DataContext="{Binding LogName, Converter={StaticResource DataFieldConverter}}" HighlightMatchCase="{Binding Element}" Loaded="EditBox_Loaded"/> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> ... </GridView> </ListView.View> </ListView> I have no idea about how to make column width autofill although I have tried a lot of way to walk up. The general idea for demo is : <ListView Name ="LogDataList" IsSynchronizedWithCurrentItem="True" ItemsSource="{Binding LogDataCollection}" Background="Cyan"> <ListView.Resources> <Style x:Key="ColumnWidthStyle" TargetType="{x:Null GridViewColumn}"> <Style.Setters> <Setter Property="HorizontalContentAlignment" Value="Stretch" > </Setter> </Style.Setters> </Style> </ListView.Resources> <ListView.View> <GridView AllowsColumnReorder="true" ColumnHeaderToolTip="Event Log Information"> <GridViewColumn Header="Event Log Name" DisplayMemberBinding="{Binding Path=LogName}" HeaderContainerStyle="{StaticResource ColumnWidthStyle}"> It works, but not accord with my demand. I need to customize datatemplate with my custom user control(MyTextBlock) since the enhancement(HighlighMatchCase property) and binding datacontext. How can I set up ColumnWidthMode with Fill in the word? On-line'in. I really appreciate your help.

• Unknown Build Error using WPF Toolkit

  - by Tom Allen

  I installed the Feb 2010 WPF Toolkit as I'm interested in evaluating the AutoCompleteBox control and I'm having extremely limited success. I can get the control to work, but as soon as I try and set any of it's properties in XAML, I get the following: Unknown build error, 'Cannot resolve dependency to assembly 'WPFToolkit, Version=3.5.40128.1, Culture=neutral, PublicKeyToken=31bf3856ad364e35' because it has not been preloaded. When using the ReflectionOnly APIs, dependent assemblies must be pre-loaded or loaded on demand through the ReflectionOnlyAssemblyResolve event. I've been testing this on a blank WPF window in a new solution. I'm guessing I'm just missing a reference or something... Here's the XAML (I've added nothing to the .xaml.cs): <Window x:Class="WpfToolkitApplication.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:toolkit="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Input.Toolkit" Title="Window1" Height="300" Width="300"> <Grid> <toolkit:AutoCompleteBox Height="25"/> </Grid> </Window> The only reference I've added is System.Windows.Controls.Input.Toolkit. Any ideas?

• Is make -j distcc possible to scale over 5 times?

  - by holmes

  Since distcc cannot keep states and just possible to send jobs and headers and let those servers to use only the data just sent and preprocess and compile, I think the lastest distcc has problem in scalability. In my local build environment which has appx. 10,000 c/c++ files to build, I could only make 2 times faster than not using distcc (but using make -j) when having 20 build servers. What do you think is the problem? If anyone has achieved scalability more than 10 - 20 times using make -j and distcc, please let me know. The following product claims that it is impossible to scale make -j and distcc faster than 5 times. http://www.electric-cloud.com/products/electricaccelerator.php I think this can be improved by: Letting the distccd server to maintain sessions Tied to those sessions, they will cache their own header directories Preprocess will be done demand base from the distccd server This will be done through a LD_PRELOADed library libdistcc.so which will replace stat/open syscalls and fetches the header files over network. ... Has anyone done this kind of thing?

• com0com silent install (test signed com0com.sys shows up as signed in explorer but not in Device Manager)

  - by Andrew

  My goal is to have the com0com serial driver install without popping up the install wizard on both WinXP and Win2000. I am working on WinXP x86. I have followed the test signing instructions for the com0com driver, replacing amd64 with i386 at line 60. I have added my test certificate as both a root and trustedprovider using the following commands: certmgr /add com0com.cer /r localMachine root certmgr /add com0com.cer /r localMachine trustedprovider And verified that it is listed under both locations. I then run the newly built setup.exe. This installs the signed com0com.sys file into C:\WINDOWS\system32\DRIVERS and sets up a pair of virtual serial ports and a bus between them. Using explorer, I go to the DRIVERS directory, right click on the com0com.sys file and verify that it has the "test" digital signature. I then go into Device Manager, open the "com0com serial port emulators" entry, pick an entry and do Properties-Driver and see that it says "Not digitally signed". I click details for the driver and can see that it is referring to the com0com.sys driver file that I just confirmed is signed. I found what might be a related issue but I'm not sure. Does WinXP demand a WHQL signature? If so, does that explain why the com0com.sys file is signed but the device driver entries say they aren't signed?

• Ericsson f3507g WWAN (3G Broadband) and AT commands

  - by JD

  I have a lenovo x200t tablet with WWAN built into it. I'm trying to connect to the internet using AT commands and a C# program which I am making so that the program can connect to the net and upload information on demand. I don't want to use Lenovo's "Access Connections" as it is too complicated for the end user. So far I have been able to use terminal to turn the card on and off, ring landlines and send SMS messages. However I can't seem to access the internet using it. I could access the net through it before I removed "Access Connections" software/bloatware. The commands I am using to try and access the net are: Connect on COM7 to the modem Send initialisation string "AT+CFUN=1" Send AT*ENAP=1,1 as suggested here (http://www.thinkwiki.org/wiki/Ericsson%5FF3507g%5FMobile%5FBroadband%5FModule) Windows says it is "Identifying" the network and a yellow exclamation mark appears on the networking icon in the task bar, but the connection fails and drops off. An IP is assigned to the "Local Area Connection 2" of 169.254.1.192 with a subnet of 255.255.0.0 - no gateway or DNS. Definately no net connection... Anyone got any ideas?

• Access <body> tag properties from form found in mediaboxAdvanced lightbox.

  - by Christopher Richa

  I am building my portfolio website simply using HTML, Flash, and the Mootools Javascript framework. I have decided to implement a theme changing feature using Javascript and cookies. When the user clicks on the "Change Theme" link, a mediaboxAdvanced lightbox appears, containing a real-time form which allows you to change the theme on the portfolio. Here's the code for the form: <div id="mb_inline" style="display: none; margin:15px;"> <h3>Change Your Theme</h3> <form> <fieldset> <select id="background_color" name="background_color"> <option value="#dcf589">Original</option> <option value="#000FFF">Blue</option> <option value="#00FF00">Green</option> </select> </fieldset> </form> </div> I know, there is no submit button, but as soon as something is changed in that form, the following Mootools code happens: var themeChanger = new Class( { pageBody : null, themeOptions : null, initialize: function() { this.pageBody = $(document.body); this.themeOptions = $('background_color'); this.themeOptions.addEvent('change', this.change_theme.bindWithEvent(this)); }, change_theme: function(event) { alert("Hello"); } }); window.addEvent('domready', function() { var themeChanger_class = new themeChanger(); }); Now this is only a test function, which should be triggered when the dropdown menu changes. However, it seems that none of it works when the form is in the lightbox! Now if I decide to run the form outside of the lightbox, then it works great! Am I missing something? If you need more examples, I will fill in on demand. Thank you all in advance. -Christopher

• Business Logic Layer Pattern on Rails? MVCL

  - by Fabiano PS

  That is a broad question, and I appreciate no short/dumb asnwers like: "Oh that is the model job, this quest is retarded (period)" PROBLEM Where I work at people created a system over 2 years for managing the manufacture process over demand in the most simplified still broad as possible, involving selling, buying, assemble, The system is coded over Ruby On Rails. The app has been changed lots of times and the result is a mess on callbacks (some are called several times), 200+ models, and fat controllers: Total bad. The QUESTION is, if there is a gem, or pattern designed to handle Rails large app logic? The logic whould be able to fully talk to models (whose only concern would be data format handling and validation) What I EXPECT is to reduce complexity from various controllers, and hard to track callbacks into files with the responsibility to handle a business operation logic. In some cases there is the need to wait for a response, in others, only validation of the input is enough and a bg process would take place. ie: -- Sell some products (need to wait the operation to finish) 1. Set a View able to get the products input 2. Controller gets the product list inputed by employee and call the logic Logic::ExecuteWithResponse('sell', 'products', :prods => @product_list_with_qtt, :when => @date, :employee => current_user() ) This Logic would handle buying order, assemble order, machine schedule, warehouse reservation, and others. Have in mind that a callback on SalesOrder is not enough, since it depends on where it is called (no field for that), depends on the class of the user, among other stuff not visible for the model, or in some cases it would take long for the model to process.

• Remove duplicates from a list of nested dictionaries

  - by user2924306

  I'm writing my first python program to manage users in Atlassian On Demand using their RESTful API. I call the users/search?username= API to retrieve lists of users, which returns JSON. The results is a list of complex dictionary types that look something like this: [ { "self": "http://www.example.com/jira/rest/api/2/user?username=fred", "name": "fred", "avatarUrls": { "24x24": "http://www.example.com/jira/secure/useravatar?size=small&ownerId=fred", "16x16": "http://www.example.com/jira/secure/useravatar?size=xsmall&ownerId=fred", "32x32": "http://www.example.com/jira/secure/useravatar?size=medium&ownerId=fred", "48x48": "http://www.example.com/jira/secure/useravatar?size=large&ownerId=fred" }, "displayName": "Fred F. User", "active": false }, { "self": "http://www.example.com/jira/rest/api/2/user?username=andrew", "name": "andrew", "avatarUrls": { "24x24": "http://www.example.com/jira/secure/useravatar?size=small&ownerId=andrew", "16x16": "http://www.example.com/jira/secure/useravatar?size=xsmall&ownerId=andrew", "32x32": "http://www.example.com/jira/secure/useravatar?size=medium&ownerId=andrew", "48x48": "http://www.example.com/jira/secure/useravatar?size=large&ownerId=andrew" }, "displayName": "Andrew Anderson", "active": false } ] I'm calling this multiple times and thus getting duplicate people in my results. I have been searching and reading but cannot figure out how to deduplicate this list. I figured out how to sort this list using a lambda function. I realize I could sort the list, then iterate and delete duplicates. I'm thinking there must be a more elegant solution. Thank you!

• Backend raising (INotify)PropertyChanged events to all connected clients?

  - by Jörg Battermann

  One of our 'frontend' developers keeps requesting from us backend developers that the backend notifies all connected clients (it's a client/server environment) of changes to objects. As in: whenever one user makes a change, all other connected clients must be notified immediately of the change. At the moment our architecture does not have a notification system of that kind and we don't have a sort of pub/sub model for explicitly chosen objects (e.g. the one the frontend is currently implementing).. which would make sense in such a usecase imho, but obviously requires extra implementation. However, I thought frontends typically check for locks for concurrently existing user changes on the same object and rather pull for changes / load on demand and in the background rather than the backend pushing all changes to all clients for all objects constantly.. which seems rather excessive to me. However, it's being argumented that e.g. the MS Entity Framework does in fact publish (INotify)PropertyChanged not only for local changes, but for all such changes including other client connections, but I have found no proof or details regarding this. Can anyone shed some light into this? Do other e.g. ORMs etc provide broadcasted (INotify)PropertyChanged events on entities?

• How to add an image when generating a pdf-file with javascript. When adding the imageLoadFromURL no pdf is generated

  - by Angu Handschuh

  I've got a problem with adding an image when generating a pdf-file with javascript. Here is my code: <!DOCTYPE html> <html> <head> <script type="text/javascript" src="base64.js"></script> <script type="text/javascript" src="sprintf.js"></script> <script type="text/javascript" src="jspdf.js"></script> <script> function demo1() { var name = prompt('Name: '); var nachname=prompt('Nachname: '); var doc = new jsPDF(); doc.setFontSize(22); doc.text(20, 20, 'Der eingegebene Text'); doc.setFontSize(16); doc.imageLoadFromUrl('image.jpg'); doc.imagePlace(20, 40); doc.text(20, 30, 'Name: ' + name); doc.text(20,40,'Nachname:'+nachname); // Output as Data URI doc.output('datauri'); } </script> </head> <body> <h2> Ein Document </h2> <a href="javascript:demo1()"> PDF erstellen </a> </body> </html> Before adding doc.imageLoadFromUrl('image.jpg'); doc.imagePlace(20, 40); the code runs without picture. It starts with a demand note for the name and the second name, after this it generates a pdf-file. But when adding the imageLoad-Method there is no pdf-file generated. Does anyone konws how to solve this problem?

• PHP Frameworks: Codeigniter vs. Yii vs. Custom?

  - by Industrial

  Hi everybody, I have used codeigniter for a some years now. Why I chosed to work with codeigniter back then? Pretty much for the extensive documentation that were available and the big user community. It made me as a totally newbie to the MVC pattern able to get a site up and running really fast. I think what is priorited from my side is that the framework doesn't affect performance too much, which Codeigniter seems to be pretty good at (when compared to other frameworks out there) and Yii, an even better option. Since the time has gone from when I started out with codeigniter, the project sizes have also increased and thereby the demand of the framework and it's footprint on the code. I have thought a few times about writing a whole new MVC framework to do only the thing's I want it to do, but it feels like reinventing the wheel and I cannot yet justify it. I am not sure whether or not it's a good solution to build a site that have the potential to become really big on either Yii or Codeigniter. I have tried to find as much as possible documentation about this comparision/issue online before posting here, but have found very few real-life arguments and stories from people that have shifted between the two PHP frameworks or have been in the same situation as me. So - what's your thoughts about Codeigniter vs. Yii vs. going custom?

• Using HAML with custom filters

  - by Guard

  Hi everybody. I feel quite excited about HAML and CoffeeScript and am working on tutorial showing how to use them in non-Rails environment. So, haml has easy to use command-line utility haml input.haml output.html. And, what is great, there exist a project (one of many forks: https://github.com/aussiegeek/coffee-haml-filter) aimed at providing custom filter that converts CoffeeScript into JS inside of HAML files. Unfortunately (or am I missing something?) haml doesn't allow specifying custom filters on the command line or with some configuration file. I (not being a Ruby fan or even knowing it enough) managed to solve it (based on some clever suggestion somewhere on SO) with this helper script: haml.rb require 'rubygems' require 'active_support/core_ext/object/blank' require 'haml' require 'haml/filters/coffee' template = ARGV.length > 0 ? File.read(ARGV.shift) : STDIN.read haml_engine = Haml::Engine.new(template) file = ARGV.length > 0 ? File.open(ARGV.shift, 'w') : STDOUT file.write(haml_engine.render) file.close Which is quite straightforward, except of requires in the beginning. Now, the questions are: 1) should I really use it, or is there another way to have on-demand HAML to HTML compilation with custom filters? 2) What about HAML watch mode? It's great and convenient. I can, of course, create a polling script in python that will watch the directory changes and call this .rb script, but it looks like a dirty solution.

• Build System with Recursive Dependency Aggregation

  - by radman

  Hi, I recently began setting up my own library and projects using a cross platform build system (generates make files, visual studio solutions/projects etc on demand) and I have run into a problem that has likely been solved already. The issue that I have run into is this: When an application has a dependency that also has dependencies then the application being linked must link the dependency and also all of its sub-dependencies. This proceeds in a recursive fashion e.g. (For arguments sake lets assume that we are dealing exclusively with static libraries.) TopLevelApp.exe dependency_A dependency_A-1 dependency_A-2 dependency_B dependency_B-1 dependency_B-2 So in this example TopLevelApp will need to link dependency_A, dependency_A-1, dependency_A-2 etc and the same for B. I think the responsibility of remembering all of these manually in the target application is pretty sub optimal. There is also the issue of ensuring the same version of the dependency is used across all targets (assuming that some targets depend on the same things, e.g. boost). Now linking all of the libraries is required and there is no way of getting around it. What I am looking for is a build system that manages this for you. So all you have to do is specify that you depend on something and the appropriate dependencies of that library will be pulled in automatically. The build system I have been looking at is premake premake4 which doesn't handle this (as far as I can determine). Does anyone know of a build system that does handle this? and if there isn't then why not?

• Several Small, Specific, MySQL Query Cache Questions

  - by Robbie

  I've look all over the web and in the questions asked here about MySQL caching and most of them seem very non-specific about a couple of questions that I have about performance and MySQL query caching. Specifically I want answers to these questions, assume for all questions that I have the query cache enabled and it is of type 2, or "DEMAND": Is the query cache per table, per database, or per server? Meaning if I have the cache size set to X and have T tables and D databases will I be caching TX, DX, or X amount of data? If I have table T1 which I regularly use the SQL_CACHE hint on for SELECT queries and table T2 which I never do, when I query T2 with a SELECT query will it check through the cache first before performing the query? *Note: I don't want to use the SQL_NO_CACHE for all T2 queries.* Assume the same situation as in question 2. If I alter (INSERT, DELETE) table T2 will any processing be done on the cache? For answers to 2 and 3, is this processing time negligible if T2 is constantly being altered and is the target of a majority of my SELECT queries?

• AspNetMembership provider with WCF service

• Writing a JMS Publisher without "public static void main"

  - by The Elite Gentleman

  Hi guys, Every example I've seen on the web, e.g. http://www.codeproject.com/KB/docview/jms_to_jms_bridge_activem.aspx, creates a publisher and subscriber with a public static void main method. I don't think that'll work for my web application. I'm learning JMS and I've setup Apache ActiveMQ to run on JBoss 5 and Tomcat 6 (with no glitches). I'm writing a messaging JMS service that needs to send email asynchronously. I've already written a JMS subscriber that receives the message (the class inherits MessageListener). My question is simple: How do I write a publisher that will so that my web applications can call it? Does it have to be published somewhere? My thought is to create a publisher with a no-attribute constructor (in there) and get the MessageQueue Factory, etc. from the JNDI pool (in the constructor). Is my idea correct? How do I subscribe my subscriber to the Queue Receiver? (So far, the subscriber has no constructor, and if I write a constructor, do I always subscribe myself to the Queue receiver?) Thanks for your help, sorry if my terminology is not up to scratch, there are too many java terminologies that I get lost sometimes (maybe a java GPS will do! :-) ) PS Is there a tutorial out there that explains how to write a "better" (better can mean anything, but in my case it's all about performance in high demand requests) JMS Publisher and Subscriber that I can run on Application Server such as JBoss or Glassfish? Don't forget that the JMS application will needs a "guarantee" uptime as many applications will use this.

• Project Architecture For Enhancing Legacy project.

  - by vijay.shad

  I am working on legacy project. Now the situation demands project to be divided into parts. What strategy I should follow to do this task. Description: The legacy project (A) is fully functional web application with almost well defined layers. But now i need to extend the project to a further enhancement. This project usage maven as build tool. But it is used only for dependency managements only. (project exported to war form inside eclipse). The new enhancement needs me to add new data table, new UI(jsp, css, js and images). What should be my strategy to enhance to application. My proposed design. I am planing to create two new projects Project B : Main Enhancement works will done in this project. Will have all layers like service layer, dao layer and UI layer in itself. And will be a web application in itself. Project C : Extract some common model and service code form project-A and create this project. This project will be added as dependency to both the projects. If my this approach is okay! Then i presume there will be problem be problem in deployment. These two projects will demand to deploy separately(currently tomcat is used). But I must deploy these two projects as one war. So, i need to have a plan to change the web.xml entries to have configurations for both projects. This will comes with some more complexities with project. What should be my design for the project? Does my plan sounds good.

• Lightweight development web server with support for PHP v2

  - by David

  In line with this question: http://stackoverflow.com/questions/171655/lightweight-web-app-server-for-php The above question has been asked numerous times and answered exactly the same in all the cases I've found using google. My question is similar to a degree but with a different desired goal: On demand development instances. I have come up with a somewhat questionable solution to host arbitrary directories in my user account for the purpose of development testing. I am not interested in custom vhosts but looking to emulate the behaviour I get when using paster or mongrel for Python & Ruby respectively. Ubuntu 9.10 TOXIC@~/ APACHE_RUN_USER=$USER APACHE_RUN_GROUP=www-data apache2 -d ~/Desktop/ -c "Listen 2990" Is there a better solution, could I do something similar with nginix or lighttpd? Note: The above won't work correctly for stock environments without a copied & altered httpd.conf. Update: The ideal goal is to mimic Paster, Webbrick, and Mongrel for rapid local development hosting. For those light weight servers, it takes less then a minute to get a working instance running ( not factoring any DB support ). Apache2 vhost is great but I've been using Apache2 for over ten years and it would be some sort of abomination hack to setup a new entry in /etc/hosts unless you have your own DNS, in which case a wildcard subdomain setup would probably work great. EXCEPT one more problem, it's pretty easy for me to know what is being hosted ( ex. by paster or mongeral ) just doing a sudo netstat -tulpn while there would be a good possibility of confusion in figure out which vhost is what.

• text-overflow:ellipsis in Firefox 4?

  - by Spudley

  The text-overflow:ellipsis; CSS property must be one of the few things that Microsoft has done right for the web. All the other browsers now support it... except Firefox. The Firefox developers have been arguing over it since 2005 but despite the obvious demand for it, they can't seem to actually bring themselves to implement it (even an experimental -moz- implementation would be sufficient). A few years ago, someone worked out a way to hack Firefox 3 to make it support an ellipsis. The hack uses the -moz-binding feature to implement it using XUL. Quite a number of sites are now using this hack. The bad news? Firefox 4 is removing the -moz-binding feature, which means this hack won't work any more. So as soon as Firefox 4 is released (later this month, I hear), we're going to be back to the problem of having it not being able to support this feature. So my question is: Is there any other way around this? (I'm trying to avoid falling back to a Javascript solution if at all possible) [EDIT] Lots of up-votes, so I'm obviously not the only one who wants to know, but I've got one answer so far which basically says 'use javascript'. I'm still hoping for a solution that will either not need JS at all, or at worst only use it as a fall-back where the CSS feature doesn't work. So I'm going to post a bounty on the question, on the off chance that someone, somewhere has found an answer.

• Optimizing PHP require_once's for low disk i/o?

  - by buggedcom

  Q1) I'm designing a CMS (-who isn't!) but priority is being given to caching. Literally everything is cached. DB rows, DB id queries, Configuration data, processed data, compiled templates. Currently it has two layers of caching. The first is a opcode cache or memory cache such as apc, eaccelerator, xcache or memcached. If an entry is not found in there it is then searched for in the secondary slow cache, ie php includes. Are the opcode caches actually faster than doing a require_once to a php file with a var_export'd array of data in it? My tests are inconclusive as my development box (5.3 of XAMPP) keeps throwing errors installing any of the aforementioned programs. Q2) The CMS has numerous helper classes that are autoloaded on demand instead of loading all files. Mostly each has a require before it so no autoloading needs to take place, however this is not the question. Because a page script can have up to 50/60 helper files included I have a feeling that if the site was under pressure it would buckle because of all the i/o that this incurs. Ignore for the moment that there is output cache in place that would remove the need for what I am about to suggest, and also that opcode caches would render this moot. What I have tried to do is join all the helper files required for the scripts execution in one single file. This is achievable and works well, however it has a side effect of greatly increasing the memory usage dramatically even though technically the same code is being used. What are your thoughts and opinions on this?

• Iterator performance contract (and use on non-collections)

  - by polygenelubricants

  If all that you're doing is a simple one-pass iteration (i.e. only hasNext() and next(), no remove()), are you guaranteed linear time performance and/or amortized constant cost per operation? Is this specified in the Iterator contract anywhere? Are there data structures/Java Collection which cannot be iterated in linear time? java.util.Scanner implements Iterator<String>. A Scanner is hardly a data structure (e.g. remove() makes absolutely no sense). Is this considered a design blunder? Is something like PrimeGenerator implements Iterator<Integer> considered bad design, or is this exactly what Iterator is for? (hasNext() always returns true, next() computes the next number on demand, remove() makes no sense). Similarly, would it have made sense for java.util.Random implements Iterator<Double>? Should a type really implement Iterator if it's effectively only using one-third of its API? (i.e. no remove(), always hasNext())

• Is there a standard lexer/parser tool for Python?

  - by Salim Fadhley

  A volunteer job requires us to convert a large number of LaTeX documents into ePub format. It's a series of open-source fiction book which has so far only been produced only on paper via a print on demand service. We'd like to be able to offer the book to users of book-reader devices (such as Kindle) which require the ePub format for best results. Fortunately, ePub is a very simple format, however there's no trivial way for LaTeX to produce the XHTML outut required. We experimented with alternative LaTeX compilers (e.g. plastex) but in the end we figured that it would probably be a lot easier to simply write our own compiler which understands a tiny subset of the LaTeX language and compiles directly to XHTML / ePub. Previously I used a tool on Windows called GOLD. This allowed me to go directly from BNF grammars to a stub parser. It also alllowed me to implement the parser in any language I liked. (I'd choose Python). This product has to work on Linux, so I'm wondering if there's an equivalent toolchain that works as well under Ubutnu / Eclipse / Python. The idea is that we will take the grammar of TeX and just implement a teeny subset of that, but we do not want to spend a huge amount of time worrying about grammar and parsing. A parser generator would obviously save us a great deal of time. Sal UPDATE 1: Bonus marks for a solution with excellent documentation or tutorials.
