• What is the proper way to create a cross-fade effect? [closed]

  - by Starx

  When creating an image slider, using a cross fade is one of more popular effects. Various sliders use differing techniques to create such an effect. Two techniques I've found so far are: Use an overlay and underlay <div> and fade in and out each other's visibility. Create a <div> matching the exact size of the slider during initialization, play with its z-index property, and then fade each other. Is there a better way to create this effect?

• Developing Good Contacts

  There are millions of was you can develop good networking contacts, but you must be open to meeting new people. In the information technology industry, everyone is a potential client. So any place you can meet people is a good place to develop good networking contacts. Here are a few examples Online Discussion Forums – Online forums are a great place to show your knowledge of a subject and allow you to meet people that share your same interests Blog Networks – Allowing others to read your thoughts and comment on them. In addition, you can so the same on other blogs with in the network. Networking Sites – Networking sites are a great way to find new contacts based on your current contacts because you can share common friends, and possibly common interests Volunteering – Volunteering is a great way to meet new contacts, and you can help others at the same time Civic Organizations – Participating in organizations or clubs like the Lions Club, Rotary Club, and religious affiliated organizations because you can meet people of all walks of life, and can share and contribute ideas for common goals Chamber of Commerce – This is another great way to meet contacts especially if you are interested in starting your own business.

• Have you tried to switch to different kind of language and find a job in a "new language" ?

  - by IAdapter

  I'm a Java programmer(J2EE/JEE), but I'm thinking about switching to C#. Does any of you have been in my position and have switched from Java to C# or C# to Java or C++ to Java, etc. ?? I'm NOT asking about switching between the same kind of languages, for example Java to Groovy/Scala/JRuby, C++ to C, VB to C#, C# to IronRuby/F#/VB.NET. Or if you company was C++, but has moved to Java(you had no choice and I'm about to make a choice). Side question: How hard was it to get a job in a "new language"?

• I'm the .1x programmer at my company. How can I best contribute?

  - by invaliduser

  I work at a newly-minted startup of five people. We have a Ph. D in machine learning, a former member of the RSpec core team, and the guy who compiles the Git binary for OS X. That's just the employees; the founder has a Ph. D and was CTO for a multi-billion-dollar corporation before leaving to start a (successful) startup, and has now left that to start this one. We also might get a guy with a Ph. D in math. Aaaaaaaaand then there's me, college-dropout intern. I think I'm pretty smart and I'm reading non-stop, but the delta of experience, skill, and knowledge between me and my co-workers is just breathtaking. So put yourself in their shoes: you've got a bright young intern who has a lot to learn but is at least energetic. What would be annoying? What use would you hope to get out of him in the here and now? What would be pleasantly surprising if it happened?

• "TDD is about design, not verification"; concretely, what does that mean?

  - by sigo

  I've been wondering about this. What do we exactly mean by design and verification. Should I just apply TDD to make sure my code is SOLID and not check if it's external behaviour is correct? Should I use BDD for verifying the behaviour is correct? Where I get confused also is regarding TDD code Katas, to me they looked like more about verification than design; shouldn't they be called BDD Katas instead of TDD Katas? I reckon that for example the Uncle Bob bowling Kata leads in the end to a simple and nice internal design but I felt that most of the process was centred more around verification than design. Design seemed to be a side effect of testing the external behaviour incrementally. I didn't feel so much that we were focusing most of our efforts on design but more on verification. While normally we are told the contrary, that in TDD, verification is a side effect, design is the main purpose. So my question is what should I focus on exactly, when I do TDD: SOLID, external API usability, or something else? And how can I do that without being focused on verification? What do you guys focus your energy on when you are practising TDD?

• Rules of Holes #6: Don't Draw Others Into the Hole with You

  - by ArnieRowland

  In the Fifth Rules of Holes, you were encouraged to seek help from others in order to extricate youself from the Hole. And it should have been clear in that Rule that you want to seek out those that can actually help you. Not everyone, or just anyone, will be able to help you get out of a Hole. Hopefully, you have a mentor, or will take the opportunity to enlist a mentor. Just be selective. Being selective will help you with Rules of Holes #5: Drawing more people into the Hole with you is not likely...(read more)

• How to avoid being an API programmer only?

  - by anything

  I have almost six years of experience in java. I have developed many projects which used frameworks like Struts, Spring, Hibernate, JQuery , DWR, Ajax etc. I have used these technologies in almost all the projects I have worked on. Projects were very simple mostly with crud based apps. My everyday tasks involves creating few screens, writing queries, testing etc. After all these years I feel like I have turned into an API programmer who just uses these above mentioned frameworks which is not giving me any satisfaction of being a programmer. Is this normal or is it just me who is feeling like this?

• Best way to protect website application code

  - by Gaz_Edge

  Background I have a web application that I host on my own server. I have clients who use the application as is, but some have asked if they can host the application on their own server. This enables them to have their own URLS rather than mine. The application only forms part of their website so I'm assuming it will not be possible for my server to respond to a direct call to their domain etc To give some examples, i currently have urls like www.mydomain.com/profile, www.mydomain.com/index.php?option=someoption&view=someview&id=1 What my clients' want is www.theirdomian.com/profile, www.theirdomian.com/index.php?option=someoption&view=someview&id=1 etc Question My question is, what is the best way for me to allow them to use their own URLs with my application, without giving them all the backend source code and databases to install on their server? One way I thought would be to create a router.php file that sits on their server. The router then asks my server to output the html. The router modifies all the links etc in the html source and outputs the new html through the clients server. When a link is clicked on the clients site, the router receives the request and modifies the url to get the data from my server etc. Is this an effective way to achieve what I want, or is it way off the mark.

• As a programmer, what's the most valuable non-English (human) language to learn?

  - by Andrew M

  I was thinking that with my developer skills, learning new languages like French, German etc. might be easier for me now. I could setup the verbs as objects in Python and use dir(verb) to find its methods, tenses and stuff ;-) But seriously, if you're a professional developer, in my case in the UK, what's the best foreign language to learn from an employment perspective? I'm thinking, like Hindi - if all our programming jobs are getting outsourced to India, might as well position yourself to be the on-site, go-between guy. Mandarin - if the Chinese become the pre-eminent economy, the new USA, in ten or twenty years, then speaking their language would open up a huge market to you. Russian - maybe another major up-and-comer, but already closer to Western standards. More IT-sector growth here than anywhere else in the coming years? Japanese - drivers of global technology, being able to speak their language could give you a big competitive advantage over other Westerners But I'm just guessing/musing with all these points. If you have an opinion, or even better, some evidence, I'd like to hear it. If the programming things falls through then at least it'll make for more interesting holidays.

• Using pkexec policy to run out of /opt/

  - by liberavia

  I still try to make it possible to run my app with root priveleges. Therefore I created two policies to run the application via pkexec (one for /usr/bin and one for /opt/extras... ) and added them to the setup.py: data_files=[('/usr/share/polkit-1/actions', ['data/com.ubuntu.pkexec.armorforge.policy']), ('/usr/share/polkit-1/actions', ['data/com.ubuntu.extras.pkexec.armorforge.policy']), ('/usr/bin/', ['data/armorforge-pkexec'])] ) additionally I added a startscript which uses pkexec for starting the application. It distinguishes between the two places and is used in the Exec-Statement of the desktopfile: #!/bin/sh if [ -f /opt/extras.ubuntu.com/armorforge/bin/armorforge ]; then pkexec "/opt/extras.ubuntu.com/armorforge/bin/armorforge" "$@" else pkexec `which armorforge` "$@" fi If I simply do a quickly package everything will work right. But if I package with extras option: quickly package --extras the Exec-statement will be exchanged. Even if I try to simulate the pkexec call via armorforge-pkexec It will aks for a password and then returns this: andre@andre-desktop:~/Entwicklung/Ubuntu/armorforge$ armorforge-pkexec (armorforge:10108): GLib-GIO-ERROR **: Settings schema 'org.gnome.desktop.interface' is not installed Trace/breakpoint trap (core dumped) So ok, I could not trick the opt-thing. How can I make sure, that my Application will run with root priveleges out of opt. I copied the way of using pkexec from synaptic. My application is for communicating with apparmor which currently has no dbus interface. Else I need to write into /etc/apparmor.d-folder. How should I deal with the opt-build which, as far as I understand, is required to submit my application to the ubuntu software center. Thanks for any hints and/or links :-)

• Bluetooth broadcasting realtime - is it possible

  - by user69961

  Is it possible to broadcast data via bluetooth to one ore more connected devices? I mean that each phone will be master and slave at the same time and each phone will broadcast data that should be received by all other phones. Or is the only possibility to use a "client-server"-like topology; one phone acts as a server and listens to all clients and then sends data from each client to the rest of clients in the network? Which variant should be more effective? If broadcasting is possible then the same implementation can be used for all devices and if one device will die communication between rest of network can continue. And also will there be enough to send one message per device - not message from each device to server and then back to all devices. Am I right?

• Which programming language should I choose I want to build this website ...? [closed]

  - by Goma

  Assuming that I will start with just phot sharing website. Every user can add comments to any photo. After that the site will contain news (general news), the admin can add any news and the moderators as well while the users can also add comments on this news. The website will aslo provide photos uploader, so every user will have up to 20 MB ti upload any photos they want. Other users can see these photos or can not depending on the option that the main user chose(if he wants to publish his photos or not). The site should have a small type of forum which provide the ability for admin to ad categories and for user to add topics and replies for each topic in these categoris. These are the things that I can think of now, but the website will add other features as well and services later on. Can you tell me now which programming language can help me to do all that? I need a programming language that provdies the follwing: 1- speed load for pages of the site. 2- easy to add more functions quickly and easy to edit code for any reason. 3- Secure 4- fast in displaying infromation from database.

• How to control gnome-terminal from Python scrypt?

  I am developing an application in PyGtk, and would like to launch a gnome-terminal and output commands to it. My user should then be able to modify the command, or maybe ignore using the up arrow ... etc. I have been able to launch a terminal, but can't work out how to send commands. This is how my application starts: class App(Gtk.Window): def __init__(self): Gtk.Window.__init__(self) process=subprocess.Popen(["gnome-terminal", "--class=App", "--name=app"], shell=False, stdout=subprocess.PIPE, stderr=subprocess.PIPE) response,error=process.communicate()

• Expected salary for software engineer? Am I under or over paid? [closed]

  - by Asdasd Asdasd

  I work for a reasonably large tech company in Boston, MA. My company has about 1.2 billion in revenue and around 3500 employees. I have 6 years of industry experience and my current pay package is as follows: Base salary: 97,000 bonus: 10,000/year (everyone always gets 100% of this... i don't know why they bother call it bonus) RSU stock: 8000/year at present day valuation. My vesting schedule covers me for the next 5 years. that brings my total pay to ~ 115,000/year Given that, would folks say I am under/average/over paid? I read so much about how engineers at google and facebook are making ridiculous sums of money (almost 200k with bonuses included) and it makes me question my pay package. thanks

• Binding in the view or the controller?

  - by da_b0uncer

  I've seen 2 different approaches with MVC on the web. One, like in ExtJS, is to bind the callbacks to the view via the controller. Finding every element on the view and adding the functionallity. The other, like in angular.js and in the lift-framework server-side, too, is to bind in the views and just write the functionallity in the controller. Which is better and cleaner? The ExtJS approach has dumb views and all the logic in the controller. Which seems clean to me. I had problems with global IDs for GUI-elements or relative navigation to GUI-elements in this approach. When I changed the view, the controller couldn't find the buttons anymore or I had multiple instances of one button with the same ID on a single application, because of the global ID. But I solved this with IDs that are only global in a view and can be on the application multiple times. So I could mess with the (dumb) views layout and design and the functionallity wouldn't break. The angular.js approach with the bindings in the view don't has the problem with global IDs. Also, the person who changes something in the view layout has to know the IDs anyway, so the controller can put the data at the right spot. So if I write <a ng-click="doThis()" /> for angular.js and implement doThis() or <a lid="buttonwhichdoesthis" /> for extjs and find the element with the local id and add doThis() as handler on the controller side, seems to be not so different. The only thing is, the second one has one more layer of indirection, which seems cleaner. The first one seems somehow to cost less effort.

• java developer who wants to raise skill level for better career growth [closed]

  - by Rahul Shivsharan

  I have an experience in Java language and in JEE related Framework for about 5 years. In these 5 years i have worked on Core java, Spring, Hibernate, JPA, Struts 1. Now just to be prepared for the near future, i am thinking to learn some new programming language or some new technology, this will help me out to be a more elligible employee. So my question to you is, which new technology or language should i learn, my target is for next 3 years. So just in case if Java fades out (thought it won't) than i can jump on to this newly learned stuff. Where should i start from ? Should i learn some other language in JVM like Scala, Clojure, Groovy, JRuby ? Or should i learn some altogether different language like Python or Erlang, Perl ? Or new technology which is related to NoSQL, like MongoDB, Hadoop, CouchDB. Or learn few current happening things in market like RoR, Node.js, LessCss or Sass, Coffee Script ? Can anybody give me some hint,

• How can I install the Play! framework using typesafe-stack? [migrated]

  - by lhk

  I'd like to create a new project with the Play! framework. My system is Mint 12 64bit. Since the newest version of Play! is already bundled with the typesafe-stack, I thought installation would be easy. I added the typesafe repo, then I apt-get updated and apt-get installed typesafe-stack with the command g8 typesafehub/play-scala. I successfully created a new project in my home folder. Now the problems begin: I don't know how to access Play! with this installation. After creating the project, I tried to convert it into an Eclipse project, it but there's no play command available in the terminal. How can I get a "standard" Play! installation on Linux? What happens to the tools bundled in the typesafe stack - Where do they go?

• Does the app need to be run from /opt directory for in the Ubuntu App Showdown?

  - by costales

  I read this question, but I'm more confused yet. In developer.ubuntu.com/showdown I read: "(2) run out of /opt" (I understand "run out" is not in /opt :O Am I wrong?) In https://wiki.ubuntu.com/AppReviewBoard/Review/Guidelines#Packaging I read: "our package should install most files in /opt/extras.ubuntu.com/" It's not clear for me if the app must be in the /opt or out /opt :$ Then, can I use the /usr? Will be the app rejected if it's on /usr? Thanks! :)

• I'm working on my resume for a job fair this week; any tips? [closed]

  - by buu700

  This will change as I update the document, but here is my resume. The job fair I'm going to is really huge (very good chance that it will determine where I intern this summer), so I would definitely appreciate any possible assistance in polishing this up. Any advice possible will be appreciated, ranging from spacing or absurdly minor formatting issues, to rearranging bullet points, to browser incompatibilities, to major changes in anything I've organised or written. At the moment, my only specific question is whether easter eggs are acceptable (specifically, if representatives who understand the reference will generally frown upon my inclusion of "Hacked The Gibson", given the context). Also, if anyone wants to evaluate it (e.g. font size, final arrangement, etc.), here is a PDF snapshot of the document at the time this question was submitted (the final version will have a different file name and appropriate metadata, for the record). Thanks!

• Why don't we use browser detection and platform-specific CSS?

  - by Pankaj Upadhyay

  Nowadays, the common phenomena is to develop a website for a browser and then corresponding apps for Android phones, iPhone, tablets and so on. Since all the platforms come with a browser, why aren't companies using CSS to accommodate them? Surely we can detect from the request which browser was used and from which platform the request came. Reading those values, why don't we just implement the corresponding CSS for different platforms. Like we do for IE, Chrome and Safari. This way we can use the platforms' browser capabilities and don't need to develop subsequent apps for a platform.

• How does URL Rewriting affect SEO?

  - by Costa

  The following paragraph is from SEO Google Guide Google is good at crawling all types of URL structures, even if they're quite complex, but spending the time to make your URLs as simple as possible for both users and search engines can help. Some webmasters try to achieve this by rewriting their dynamic URLs to static ones; while Google is fine with this, we'd like to note that this is an advanced procedure and if done incorrectly, could cause crawling issues with your site. What makes URL re-writing implementation incorrect for GoogleBot? I am using Asp.net 3.5 framework.

Shawn started out giving us a set of bad design/good design examples.  They very effectively showed how good design gives a sense of professionalism to your app that could determine if your wonderful idea actually makes money is DOA. I won’t go over all his points since you will be able to get the session online, but a few of his checklist points included design from the beginning instead of as an afterthought, not being afraid to leave white space and making sure your application elegantly supports both landscape and portrait modes.  The many gems make this a must watch for any developers who struggle with visual design. del.icio.us Tags: BUILD 2013,Windows Phone,XAML,Design

• Stop myself from over-complicating applications

  - by stuartmclark

  Recently I worked on a fairly large project involving C# and MVVM. This application had around 160 projects in the solutions each seprarated into their own layers. As I have been working on this application for almost a year, building it from scratch as part of a team, I am now coming off that project and onto smaller more trivial projects. As I was beginning to develop a small in-house tool I found myself trying to mimic the larger applications structure and layering but in the end I just had a simple application with several DLLs which I know I wouldn't have done if I had not worked on that larger application before. I am just wondering if there are any techniques I can utilise to stop myself from turning a "code-behind" style trivial application into a full blown MVVM application? Or should I continue developing as I am and try to keep the unnecessary fluff out of the project?

• Plays Well With Others - Influence versus Authority

  - by KKline

  Originally appearing on http://KevinEKline.com on Nov 13, 2010 You’ve probably found that the prefix “lead” is a fairly common occurrence in the technology world. We have “lead developers”, “lead DBAs”, “lead architects”, and “lead consultants”. Yet, we don’t have “lead managers”, “lead directors”, or “lead VPs”. Why is that? Well, there are probably a number of different reasons for having “lead” technologist titles depending on who you ask. For example, the HR department might say that adding “lead”...(read more)
