• 1 iPhone, 2 (potentially 3) Macs......& Google Apps Sync?!

  - by Goober

  Currently I use a beast of a G5 Mac at work for all my software/web development, an iMac G5 at home for personal use & a MacBook Pro for when i'm on the go. At work we make heavy use of all the Google Apps features such as calendar & docs etc. We all have an address book (local mac application) that gets synced with a list of contacts stored on our mail server. I want to be able to integrate the Google Apps calendar with my iPhone calendar (or even just iCal - which i can then sync to the iPhone). Essentially I want all three Macs to have the Google calendar synced to their version of iCal including the iPhone. I've heard that Google Sync handles something along these lines but i'm unsure if it's going to fulfill my needs? I'm trying my best to avoid having to use MobileMe..... Help greatly appreciated, Kind regards

• Is it bad to be the only person supporting software you have developed?

  - by trpt4him

  My employer has a need for a web-based application to manage and share data within the department, with approximately 50-75 possible users. I feel I have the ability to write it for them. I would likely use Python/Django with a MySQL database, so it would be open source. However, I'm the only IT person in my department (our larger organization has a separate IT support staff with which I often work, but not for web development). I want to develop this application, but if I leave in 1-2 years, and someone else has to come in after me and support it, will this be seen as a bad decision? This is assuming all the obvious points -- I will write documentation, I will comment my code, and I will strive to follow good application design principles. But will that be enough? In principle, is it acceptable for one person to develop and support an entire web application? Is this a "do first, then show and ask" kind of situation, or should I be certain it will be adopted by everyone involved first?

• Getting iTunes to play third party AAC files

  - by Redmastif

  I have a library filled with some old MP3 files and I'm in the process of changing them all to AAC for the better sound quality. Obviously I can't just create AAC versions of the files I already have because they would sound worse (lossy compression to converted to more lossy compression), so I'm going to their source and downloading them in a lossless form and using a third party to make them into AAC. Apparently iTunes will not handle AAC files that aren't made with iTunes. Is there a way around this? I've looked at third party programs and would be willing to use them, but since they all require the iTunes/iPod/iEverything driver, I don't know if they would still prevent my files or not. Also before you jump on my back about pirating, these files are from old CDs that I lost years ago. I paid for them. Thanks.

• Is it possible to temporarily disable non-global zones?

  - by Gary

  I frequently need to install a package on the global zone for a quick test on a development box. When there are multiple prompts for one package I have to answer them for each zone. If the zone is not running then I need to wait for the zone to start up, answer the prompts, etc. This is particularly annoying when if I'm getting packages from http://www.sunfreeware.com and using the pkg-get utility which nicely pulls in dependencies for you. Can I disable the zones temporarily? I haven't found a way to do this. Thanks.

• Compressing/compacting messages over websocket on Node.js

  - by icelava

  We have a websocket implementation (Node.js/Sock.js) that exchanges data as JSON strings. As our use cases grow, so have the size of the data transmitted across the wire. The websocket protocol does not natively offer any compression feature, so in order to reduce the size of our messages we'd have to manually do something about the serialisation. There appear to be a variety of LZW implementations in Javascript, some which confuses me on their compatibility for in-browser use only versus transmission across the wire due to my lack of understanding on low-level encodings. More importantly, all of them seem to take a noticeable performance drag when Javascript is the engine doing the compression/decompression work, which is not desirable for mobile devices. Looking instead other forms of compact serialisation, MessagePack does not appear to have any active support in Javascript itself; BSON does not have any Javascript implementation; and an alternative BISON project that I tested does not deserialise everything back to their original values (large numbers), and it does not look like any further development will happen either. What are some other options others have explored for Node.js?

• Using Clojure instead of Python for scalability (multi core) reasons, good idea?

  - by Vandell

  After reading http://clojure.org/rationale and other performance comparisons between Clojure and many languages, I started to think that apart from ease of use, I shouldn't be coding in Python anymore, but in Clojure instead. Actually, I began to fill irresponsisble for not learning clojure seeing it's benefits. Does it make sense? Can't I make really efficient use of all cores using a more imperative language like Python, than a lisp dialect or other functional language? It seems that all the benefits of it come from using immutable data, can't I do just that in Python and have all the benefits? I once started to learn some Common Lisp, read and done almost all exercices from a book I borrowod from my university library (I found it to be pretty good, despite it's low popularity on Amazon). But, after a while, I got myself struggling to much to do some simple things. I think there's somethings that are more imperative in their nature, that makes it difficult to model those thins in a functional way, I guess. The thing is, is Python as powerful as Clojure for building applications that takes advantages of this new multi core future? Note that I don't think that using semaphores, lock mechanisms or other similar concurrency mechanism are good alternatives to Clojure 'automatic' parallelization.

• How safe is it to rely on thirdparty Python libs in a production product?

  - by skyler

  I'm new to Python and come from the write-everything-yourself world of PHP (at least this is how I always approached it). I'm using Flask, WTForms, Jinja2, and I've just discovered Flask-Login which I want to use. My question is about the reliability of using thirdparty libraries for core functionality in a project that is planned to be around for several years. I've installed these libraries (via pip) into a virtualenv environment. What happens if these libraries stop being distributed? Should I back up these libraries (are they eggs)? Can I store these libraries in my project itself, instead of relying on pip to install them in a virtualenv? And should I store these separately? I'm worried that I'll rely on a library for core functionality, and then one day I'll download an incompatible version through pip, or the author or maintainer will stop distributing it and it'll no longer be available. How can I protect against this, and ensure that any thirdparty libraries that I use in my projects will always be available as they are now?

• Authenticate native mobile app using a REST API

  - by Supercell

  I'm starting a new project soon, which is targeting mobile application for all major mobile platforms (iOS, Android, Windows). It will be a client-server architecture. The app is both informational and transactional. For the transactional part, they're required to have an account and log in before a transaction can be made. I'm new to mobile development, so I don't know how the authentication part is done on these platforms. The clients will communicate with the server through a REST API. Will be using HTTPS ofcourse. I haven't yet decided if I want the user to log in when they open the app, or only when they perform a transaction. I got the following questions: 1) Like the Facebook application, you only enter your credentials when you open the application for the first time. After that, you're automatically signed in every time you open the app. How does one accomplish this? Just simply by encrypting and storing the credentials on the device and sending them every time the app starts? 2) Do I need to authenticate the user for each (transactional) request made to the REST API or use a token based approach? Please feel free to suggest other ways for authentication. Thanks!

• Mutliple VMs for Tomcat cluster vs Multiple Tomcat instances on one physical box

  - by Greymeister

  I'm working on a project that will be implemented into production using a cluster of Apache Tomcat instances and I'm looking for the best Hardware/OS solutions and VMs have come up as one option. I have run ESXi/ESX instances before for development and testing, but I'm curious for a hosting environment if having multiple VMs is actually worse than just configuring a server to host multiple instances of Tomcat. These are my guesses: Pros for VMWare Easier Maintenance/Backup for individual VMs (VMWare makes this easy) Can remote login to individual VMs without having to give host access (security?) Easier way to re-purpose machine for OS/Hardware changes Pros for running on one Physical Machine Overhead of only one OS (also no VMWare footprint) Update OS/security changes once One less administrative layer (No VM expertise required) I'm curious if anyone has any other ideas about what the benefits would be for either option.

• 504 Gateway Time-out after php fatal error

  - by tiagojsag

  I'm using nginx and php-fpm to develop a symfony2 based website, under ubuntu 12.10 (yes, I know I'm using a beta OS). Everything was working out fine until, due to an error on my code, I called an unexisting function, and got the following: Fatal error: Call to a member function (....) This isn't a problem (it's a bug in my code, easily fixable), but after this, no other page loads. My browser just keeps trying to load the page from the webserver, until nginx timeouts (after +- 30s, which should be some default timeout) and returns: 504 Gateway Time-out Restarting php-fpm solves the issue. Nginx logs show a timeout message, and nothing appears on php-fpm logs, even if I set them to debug level. I tried switching from fpm to fastcgi, and the same thing happens. I've looked around, but all similar error are related to big requests/file handling, which isn't the case. All the pages on my website load in a few seconds, even under development conditions (no caching, etc).

• Enable Ctrl (or Alt) + arrow keys to mimic 'home' and 'end' functionality

  - by YuKagi

  I am a long time Mac user and I'm now using a Ubuntu machine for development, and while I'm more or less used to a lot of the keyboard shortcuts, one thing I can't get used to is using the 'Home' and 'End' keys to move around lines of text. On a Mac you use "Command + right arrow" to go to the end of a line and "Command + left arrow" to go to the beginning. Is there a way to enable this kind of functionality in Linux? I'm not sure if this would be considered remapping, keyboard shortcuts, or what...

• Install multiple PHP environments on OS X Snow Leopard

  - by Darren Newton

  I just upgraded my MBP to Snow Leopard (OS X 10.6), which took PHP to 5.3 This is great, except I use my MBP as my development machine and I use a lot of PHP libs and frameworks (namely CakePHP 1.2) which are not compatible at the moment with PHP 5.3. CakePHP in particular does not have a stable version for PHP 5.3 so its not a matter of upgrading the framework (and the production servers are under PHP 5.2 anyway.) Is there a way to install PHP 5.2.9 alongside PHP 5.3 and then using httpd.conf or .htaccess tell Apache which version of PHP to use for a particular directory? Alternatively is there a way to do this with MacPorts? Thanks!

• #altnetseattle - Kanban

  - by GeekAgilistMercenary

  The two main concepts of Kanban is to keep the queues minimum and to maintain visibility. Management/leadership needs to make sure the Kanban Queue doesn’t get starved.  This is key and also very challenging, being the queue needs to be minimal but also can’t get too small during the course of work.  This is to maintain maximum velocity. Phases of the Kanban need to be kept flowing too, bottlenecks need removed ASAP when brought up. Victory Wall – I dig that idea.  Somewhere to look to see the success of the team. The POs work in Rally or other tools for some client management, but it causes issues with the lack of "visibility" – a key fundamental ideal & part of Kanban. One of the big issues is fitting things into a sprint, when Kanban is used with Scrum, but longer sprints are wasteful. Kanban work sizes are of a set size. At this point I got a bit side tracked by the actual conversation and missed out on note taking.  Overall, people doing Kanban and Lean Style Software Development I would say are some of the happiest coders around.  The clean focus, good velocity, sizing, and other approaches that are inferred by Kanban help developers be the rock stars and succeed. This is definitely a topic I will be commenting on a lot more in the near future.

• A few tips on deploying Secure Enterprise Search with PeopleSoft

  - by Matthew Haavisto

  Oracle's Secure Enterprise Search is part of PeopleSoft now.  It is provided as part of the Peopltools platform as an appliance, and is used with applications starting with release 9.2.  Secure Enterprise Search is a rich and powerful search product that can enhance search and navigation in PeopleSoft applications.  It also provides useful features like facets and filtering that are common in consumer search engines.Several questions have arisen about the deployment of SES and how to administer it and insure optimum performance.  People have also asked about what versions are supported on various platforms.  To address the most common of these questions, we are posting this list of tips.Platform SupportSES 11.1.2.2 does not support some of the platforms supported by PeopleTools, such as Windows 2012 and AIX 7.1. However, PeopleSoft and SES can use different operating system platforms when SES is deployed on a separate machine.SES 11.2.2.2 will have the required platform support for PT 8.53 in the future. We are planning to certify PT 8.53 once the testing is complete in 8.54 development and all platform support is released for 11.2.2.2.ArchitectureWe recommend running SES on a separate machine (from your apps) for two reasons:1.    SES bundles specific WebLogic, Java, and Oracle DB versions and might need different OS patches at a minimum than PeopleSoft. By having SES run on a different machine, these pre-requisites can be managed better through their lifecycle independenly for PeopleSoft and SES.2.    SES is resource intensive - it runs it's own WebLogic and Oracle database. By having SES run on its own machine, sufficient resources can be allocated to SES and free the PeopleSoft servers from impacts of SES load patterns.We will be providing a comprehensive red paper covering PeopleSoft/SES administration in the near future, but until that is published, we'll post tips on this blog.

• Gems In The Visual Studio 2010 Training Kit &ndash; Introduction to MEF: Learning Labs

  - by Jim Duffy

  No, this post doesn’t have anything to do with cooking up illegal drugs in some rundown shack outside of town. That, my friends, would be a meth lab and fortunately that is waaaaay outside my area of expertise. Now I can talk Kentucky bourbon, or as Homer Simpson would say “mmmmmmmmmmm bourbon”, with you but please refrain from asking me meth questions. :-) Anyway, what I’m talking about are the MEF (Managed Extensibility Framework) Learning Labs contained in the Visual Studio 2010 and .NET Framework 4 Training Kit. Not sure what MEF is and need an overview? Then start here or here. Ok, so you’ve read a bit about MEF or heard about MEF and you’re thinking it might be something you and your development team might want to take a hands-on look at. I have good news then because contained in the Visual Studio 2010 and .NET Framework 4 Training Kit is a series of hands-on learning labs for MEF. I’ve added working my way through them to my “things I want to take a closer look at” list. Have a day. :-|

• Using HTML5 Today part 4&ndash;What happened to XHTML?

  - by Steve Albers

  This is the fourth entry in a series of descriptions & demos from the “Using HTML5 Today” user group presentation. For practical purposes, the original XHTML standard is a historical footnote, although XHTML transitional will probably live on forever in the default web page templates of old web page editors. The original XHTML spec was released in 2000, on the heels of the HTML 4.01 spec.  The plan was to move web development away from HTML to the more formal, rigorous approach that XHTML offered, but it was built on a principle that conflicts with the history and culture of the Internet: XHTML introduced the idea of Draconian Error Handling, which essentially means that invalid XML markup on a page will cause a page to stop rendering. There is a transitional mode offered in the original XHTML spec, but the goal was to move to D.E.H.  You can see the result by changing the doc type for a document to “application/xhtml+xml” - for my class example we change this setting in the web.config file: <staticContent> <remove fileExtension=".html" /> <mimeMap fileExtension=".html" mimeType="application/xhtml+xml" /> </staticContent> With the new strict syntax a simple error, in this case a duplicate </td> tag, can cause a critical page error: While XHTML became very popular in the ensuing decade, the Strict form of XHTML never achieved widespread use. Draconian Error Handling was one of the factors that led in time to the creation of the WHATWG, or Web Hypertext Application Technology Group.  WHATWG contributed to the eventually disbanding of the XHTML 2.0 working group and the W3C’s move to embrace the HTML5 standard. For developers who long for XML markup the W3C HTML5 standard includes an XHTML5 syntax. For the longer, more definitive look at what happened to XHTML and how HTML5 came to be check out the Dive Into HTML mirror site or Bruce Lawson’s “HTML5: Who, What, When Why” talk.

• Mass editing videos on Ubuntu?

  - by rick

  Hi, I'm trying to add a watermark and a credits image to all of my old videos. I downloaded them off YouTube so they are all flv (H.264?). Is there some software that will allow me do simple edits in batches? I know a little bit of Python and tried looking at some of the library but they all seem like overkill (and way above my head). So is there a solution besides getting some software and going through all my videos and doing it manually? They are all mostly the same length, but it would be nice to specify a relative position for my credits. e.g. show a static image for 10 seconds when the video is at 95%

• Easy to use JSON Web Service Hosts?

  - by Serguei Fedorov

  I saw this being used by someone in a college class once and cannot find anything that is analogous to it. I am not sure if this is the right place to ask about something like this, but hopefully I can get some direction. I want to write an app which uses web services that can obtain and push data back to the client apps. Right now I am gathering up the design and documentation of this app. Not having to code the web service myself would reduce development time by a lot; instead using an easy to setup web service that will be easy to setup and manage. Either XML based on JSON based is totally fine; though I would prefer JSON for its reduced overhead. Like I said I have seen this demonstrated before; you define the data structure to be stored and how it is treated. I cannot find the person who demonstrated this; hopefully maybe someone can suggest something? The service he used was free with a limited amount of requests allowed. EDIT: He was using an online service to do this not a script which is installed onto an existing web hosting account. Thank you!

• How do I configure Shrewsoft's VPN client to only route traffic to a certain IP address through the VPN?

  - by dommer

  We're using Shrewsoft's VPN client to connect to a third party development server. However, it seems to be configured to send all or nothing through the VPN. The devs have to disconnect from the VPN to get email/internet access back. The server that needs to be accessed via the VPN is on a specific (local - 10.x.x.x) IP address and a specific ports. Can we configure the Shrewsoft client application to only route traffic to that one address and/or port through the VPN and to route anything else though the usual channels? If so, how is it done? I'm not a VPN specialist and the options are confusing. In the absence of any Shewsoft VPN client specific advice, what should I be search for? Split tunnels?

• Mobile Web Framework that will only control rendering and page transitions

  - by rlemon

  I have been using jQueryMobile for a bit now, and there are some things I like about it and others I do not. First I will give a bit of background. I have a light weight mobile application that has a few configurations and 6 pages. Ideally I Would like to load all pages into the DOM (they interact with each other quite often and pages will be switched in the same frequency). The application will post for some JSON every n seconds and refresh the values on the page (yes it is primarily a information display app). with the jQuery Mobile framework the only real thing I like is how easy it is to have a standardized UI a crossed all devices and browsers, I'm really not using too much else out of the framework other than the basic page navigation (if you are familiar with the framework; a bare-bone multi-page design is all i need). Why I want to step away from jQueryMobile is how weighty it is. Not only do you need to include the mobile library, but also the base jQuery libraries. This I do not like because I'm not using jQuery anywhere else on the site. Any suggestions on light-weight mobile frameworks that have a similar rendering as jQueryMobile?

• Am I programming too slow?

  - by Jonn

  I've only been a year in the industry and I've had some problems making estimates for specific tasks. Before you close this, yes, I've already read this: http://programmers.stackexchange.com/questions/648/how-to-respond-when-you-are-asked-for-an-estimate and that's about the same problem I'm having. But I'm looking for a more specific gauge of experiences, something quantifiable or probably other programmer's average performances which I should aim for and base my estimates. The answers range from weeks, and I was looking more for an answer on the level of a task assigned for a day or so. (Note that this doesn't include submitting for QA or documentations, just the actual development time from writing tests if I used TDD, to making the page, before having it submitted to testing) My current rate right now is as follows (on ASP.NET webforms): Right now, I'm able to develop a simple data entry page with a grid listing (no complex logic, just Creating and Reading) on an already built architecture, given one full day's (8 hours) time. Adding complex functionality, and Update and Delete pages add another full day to the task. If I have to start the page from scratch (no solution, no existing website) it takes me another full day. (Not always) but if I encounter something new or haven't done yet it takes me another full day. Whenever I make an estimate that's longer than the expected I feel that others think that I'm lagging a lot behind everyone else. I'm just concerned as there have been expectations that when it's just one page it should take me no more than a full day. Yes, there definitely is more room for improvement. There always is. I have a lot to learn. But I would like to know if my current rate is way too slow, just average, or average for someone no longer than a year in the industry.
