  - by Gopinath

  Android is the Windows of next generation. Its open, free, widely adopted and smart enough to outsmart Apple’s iOS. It’s a stolen product and cheap imitation of iOS, but Steve Job’s once quoted saying good artists copy and great artists steal. Alright, this post is not about Android vs iOS or is it really stolen or not. Android is a great OS for mobile devices and it lets you do amazing through mobiles.  In this post I want to write about the geeky things we can do with an Android Smartphone.

• Single python file distribution: module or package?

  - by DanielSank

  Suppose I have a useful python function or class (or whatever) called useful_thing which exists in a single file. There are essentialy two ways to organize the source tree. The first way uses a single module: - setup.py - README.rst - ...etc... - foo.py where useful_thing is defined in foo.py. The second strategy is to make a package: - setup.py - README.rst - ...etc... - foo |-module.py |-__init__.py where useful_thing is defined in module.py. In the package case __init__.py would look like this from foo.module import useful_thing so that in both cases you can do from foo import useful_thing. Question: Which way is preferred, and why? EDIT: Since user gnat says this question is poorly formed, I'll add that the official python packaging tutorial does not seem to comment on which of the methods described above is the preferred one. I am explicitly not giving my personal list of pros and cons because I'm interested in whether there is a community preferred method, not generating a discussion of pros/cons :)

• Need advice on design in Ruby On Rails

  - by Elad

  For personal educational purposes I am making a site for a conference. One of the object that exist in a conference is a session, which has different states and in each state it has slightly different attributes: When submitted it has a speaker (User in the system), Title and abstract. When under review it has reviews and comments (in addition to the basic data) When accepted it has a defined time-slot but no reviewers anymore. I feel that it is not the best thing to add a "status" attributes and start adding many if statements... So I thought it would be better to have different classes for each state each with it's own validations and behaviors. What do you think about this design? Do you have a better idea? *I must add this out of frustration: I had several edits of the question, including one major change but no one actually gave any hint or clue on which direction should i take or where is a better place to ask this... Hardly helpful.

• Computer-controlled Lights and Music Synced into Christmas Rock Spectacular

  - by Jason Fitzpatrick

  This spectacular computer controlled and synchronized lighting display combines thousands of feet of LED lighting, multiple controllers, and a rock medley to great effect. The above display started life as the personal Christmas light display of Sioux Falls, ND resident Joe Noe. When Noe moved, he donated his display to a local mall in order to preserve the tradition of people stopping by to see it and making donations to the Make-A-Wish foundation. The local mall, Western Mall, expanded the display and added in even more LEDs and controllers. The end result is an impressive display synced to a Christmas rock medley by UK musician Richard Campbell.

• In-app paymnt methods

  - by user212228

  I'm interested in developing for Ubuntu (mostly phones) and I can't seem to find the guidelines on app publishing, will apps only work through the ubuntu software center, or can users download and install an app from a website like is possible with an android apk? Also, are there any rules regarding in-app purchase methods, (I hope the minimum price here isn't $2.99 in-app as well or I'm not going to even bother developing for Ubuntu and will just stick with Android) Google for example, requires that in-app purchases go through their servers so that it isn't possible to use other funding methods at least for play store published apps. My main questions here are: Would it be possible to release an app for ubuntu touch that accepted bitcoin, paypal, or other methods for in-app purchases? If not, would it be possible to release apps through a personal website or 3rd party app market that could use alternative payment methods?

• Website development from scratch v/s web framework [duplicate]

  - by Ali

  This question already has an answer here: What should every programmer know about web development? 1 answer Do people develop websites from scratch when there are no particular requirements or they just pick up an existing web framework like Drupal, Joomla, WordPress, etc. The requirements are almost similar in most cases; if personal, it will be a blog or image gallery; if corporate, it will be information pages that can be updated dynamically along with news section. And similarly, there are other requirements which can be fulfilled by WordPress, Joomla or Drupal. So, Is it advisable to develop a website from scratch and why ? Update: to explain more as got commentt from @Raynos (thanks for comment and helping me clearify the question), the question is about: Should web sites be developed and designed fully from scratch? Should they be done by using framework like Spring, Zend, CakePHP? Should they be done using CMS like Joomla, WordPress, Drupal (people in east are using these as frameworks)?

• Is Ubuntu workable as a laptop for an IT consultant?

  - by Eric Wilson

  I work as a consultant programmer, typically in large businesses. I use a Windows Laptop, and many of my colleagues use a Mac. My personal preference would be to run Ubuntu if I could have complete control over my development environment. But I will have occasional need for Microsoft specific products, especially IE. My colleagues that use a Mac often run Windows on a virtual machine for these situations. My question is: Is Ubuntu a workable solution for the laptop of an enterprise programmer? For example, is it as easy to run Windows on a VM on Ubuntu as it is on a Mac? Has anyone out there tried this? Is there any particular reason why Ubuntu would not serve as well as a Mac for development in this environment? Note that I am not doing .NET development, so I am typically dealing with Java that is going to be run on an Apache server and used by clients running Windows.

• Moving Forward with Code Iteration

  - by rcapote

  There are times when working on my programming projects, and I get to a point where I'm ready to move on to the next part of my program. However, when I sit down to implement this new feature I get stuck, in a sense. It's not that I don't know how to implement the feature, it's that I get stuck on figuring out the best way to implement said feature. So I sit back for a day or two and let the ideas ferment until I am comfortable with a design. I get worried that I may not write something as well as it could be, or that I might have to go back and rework the whole thing; so I put it off. This is a big reason why I've never really finished many personal projects. Anyone else experience this, and how do you keep your self moving forward in your project?

• YouSendIt Alternative?

  - by WuckaChucka

  Looking for a reasonably priced alternative to YouSendIt's exorbitant pricing for an embedded, unbranded (i.e. no "Uploads by SomeCompany" or at the very least, discrete, subtle co-branding) file upload solution for my client's print shop Website. To do what we want to do with YouSendIt, we're looking at a corporate account of $995 USD plus $29.99 USD monthly fee, that is only sold pro-rated, so you have to buy the entire year's worth. To me, this is just unacceptable considering the commodity pricing of storage and bandwidth nowadays. For data, we're looking at roughly 10MB per upload, with perhaps 250-1000 uploads per month, with transient data storage of no more than 30 days (and more than likely 1-2 business days) for a total of 10 GB transfer (upload) and 10 GB transfer (download, to the print shop) at the very max each month. Any ideas? Everything I've found through searching seems to be geared more towards personal file sharing and not for embedding into Websites. Thanks

• How to represent a tree structure in NoSQL

  - by Vlad Nicula

  I'm new to NoSQL and have been playing around with a personal project on the MEAN stack (Mongo ExpressJs AngularJs NodeJs). I'm building a document editor of sorts that manages nodes of data. Each document is actually a tree. I have a CRUD api for documents, to create new trees and a CRUD api for nodes in a given document. Right now the documents are represented as a collection that holds everything, including nodes. The children parent relationship is done by ids. So the nodes are an map by id, and each node has references to what nodes are their children. I chose this "flat" approach because it is easier to get a node by id from a document. Being used to having a relation table between nodes and documents, a relation table between nodes and children nodes I find it a bit weird that I have to save the entire "nodes" map each time I update a node. Is there a better way to represent such a data type in NoSQL?

• Are there any non-self-taught famous programmers? [closed]

  - by Jon Purdy

  It seems to me that being a self-taught programmer has significant advantages over picking it up only in higher education. Not only does a self-taught developer have a headstart on their 10 000-odd hours of mastery, but their hobby demonstrates genuine interest. This will likely lead to a process of continuous self-improvement over their career, not to mention increased likelihood of producing personal projects that are worthy of fame. A programmer who spends four years in study (not nearly all of which is going to be directly concerned with programming) has far less leisure to explore and learn independently than does a developer who starts college with even a few years of dedicated hobbyist study. I wonder whether there are any famed developers who had no exposure to programming before deciding to study it in university. I simply doubt that an 18-year-old has the capacity to become a brilliant programmer with no prior experience, but that seems like an awfully elitist and unpleasant view, so I'd like to be proven wrong.

• What are the downsides to using dependency injection?

  - by kerry

  I recently came across an interesting question on stack overflow with some interesting reponses.  I like this post for three reasons. First, I am a big fan of dependency injection, it forces you to decouple your code, create cohesive interfaces, and should result in testable classes. Second, the author took the approach I usually do when trying to evaluate a technique or technology; suspend personal feelings and try to find some compelling arguments against it. Third, it proved that it is very difficult to come up with a compelling argument against dependency injection. What are the downsides to using dependency injection?

• When should I make the first commit to source control?

  - by Kendall Frey

  I'm never sure when a project is far enough along to first commit to source control. I tend to put off committing until the project is 'framework-complete' and primarily commit features from then on. (I haven't done any personal projects large enough to have a core framework too big for this.) I have a feeling this isn't best practice, though I'm not sure what all could go wrong. Let's say, for example, I have a project which consists of a single code file. It will take about 10 lines of boilerplate code, and 100 lines to get the project working with extremely basic functionality (1 or 2 features). Should I first check in: The empty file? The boilerplate code? The first features? At some other point? Also, what are the reasons to check in at a specific point?

• Custom Themes Introduced in Gmail

  As we all know, Google Team introduced a number of HD themes last November. Now they are giving us an option of customizing our own background. We can put in our own images, select from our Google+ photos or just paste any image URL. Or we can browse the Featured Photos section to find the image that we like. They are introducing custom themes with two options, Light and Dark. In the Featured tab, we can simply search for specific kind of pictures like “hdr scenery” or “bokeh wallpaper” and so on. We can easily maintain our personal or work accounts with different background images that suites the best. The company announced this information in their blog today.

• The WaitForAll Roadshow

  - by adweigert

  OK, so I took for granted some imaginative uses of WaitForAll but lacking that, here is how I am using. First, I have a nice little class called Parallel that allows me to spin together a list of tasks (actions) and then use WaitForAll, so here it is, WaitForAll's 15 minutes of fame ... First Parallel that allows me to spin together several Action delegates to execute, well in parallel.   public static class Parallel { public static ParallelQuery Task(Action action) { return new Action[] { action }.AsParallel(); } public static ParallelQuery> Task(Action action) { return new Action[] { action }.AsParallel(); } public static ParallelQuery Task(this ParallelQuery actions, Action action) { var list = new List(actions); list.Add(action); return list.AsParallel(); } public static ParallelQuery> Task(this ParallelQuery> actions, Action action) { var list = new List>(actions); list.Add(action); return list.AsParallel(); } }   Next, this is an example usage from an app I'm working on that just is rendering some basic computer information via WMI and performance counters. The WMI calls can be expensive given the distance and link speed of some of the computers it will be trying to communicate with. This is the actual MVC action from my controller to return the data for an individual computer.  public PartialViewResult Detail(string computerName) { var computer = this.Computers.Get(computerName); var perf = Factory.GetInstance(); var detail = new ComputerDetailViewModel() { Computer = computer }; try { var work = Parallel .Task(delegate { // Win32_ComputerSystem var key = computer.Name + "_Win32_ComputerSystem"; var system = this.Cache.Get(key); if (system == null) { using (var impersonation = computer.ImpersonateElevatedIdentity()) { system = computer.GetWmiContext().GetInstances().Single(); } this.Cache.Set(key, system); } detail.TotalMemory = system.TotalPhysicalMemory; detail.Manufacturer = system.Manufacturer; detail.Model = system.Model; detail.NumberOfProcessors = system.NumberOfProcessors; }) .Task(delegate { // Win32_OperatingSystem var key = computer.Name + "_Win32_OperatingSystem"; var os = this.Cache.Get(key); if (os == null) { using (var impersonation = computer.ImpersonateElevatedIdentity()) { os = computer.GetWmiContext().GetInstances().Single(); } this.Cache.Set(key, os); } detail.OperatingSystem = os.Caption; detail.OSVersion = os.Version; }) // Performance Counters .Task(delegate { using (var impersonation = computer.ImpersonateElevatedIdentity()) { detail.AvailableBytes = perf.GetSample(computer, "Memory", "Available Bytes"); } }) .Task(delegate { using (var impersonation = computer.ImpersonateElevatedIdentity()) { detail.TotalProcessorUtilization = perf.GetValue(computer, "Processor", "% Processor Time", "_Total"); } }).WithExecutionMode(ParallelExecutionMode.ForceParallelism); if (!work.WaitForAll(TimeSpan.FromSeconds(15), task => task())) { return PartialView("Timeout"); } } catch (Exception ex) { this.LogException(ex); return PartialView("Error.ascx"); } return PartialView(detail); }

• What do you do when you realize your job requires you to do something out of your depth?

  - by Billy ONeal

  For a large software project recently, I was really out of my depth. And I did actually know this; and that the only reason I was employed was mostly a lack of other qualified candidates. The job was to build a large application on top of PHP/MySQL, a system I had little experience with. (I did advise the employer of this beforehand -- I've been spoiled by C# ASP.NET/MVC and MSSQL Server) The main reason I applied was location, location, location -- on campus jobs which actually have any programming component are relatively rare. For almost a year and a half I've slogged through this, and I think I can say I know (at least somewhat) what I'm doing now. I've made some mistakes, torn out some hair, and moved on. (I'm still working on this system nowadays, but I no longer feel completely lost) In the future though, I'd like to keep my personal and professional self a little healthier than what occurred in this case. So I'm curious -- what's the best way to handle a situation like this?

• Country specific SEO

  - by John

  I have a wordpress site which is located at a .com address. The site is a simple 4 page personal site with my academic credentials, publications and a health blog that I started. I have done quite a bit of seo and I rank pretty high for the keywords i want on google.co.uk. However, I do not rank at all on google.com.mt which is the Malta specific search. I have therefore just bought the .com.mt domain and pointed the DNS nameservers to my current host provider and redirected it to the .com address. My goal is to make sure I don't screw up my google.co.uk search ranking, while starting to rank on google.com.mt I'm I doing the right thing or do you have any suggestions??

• Books and stories on programming culture, specifically in the 80's / early 90's

  - by Ivo van der Wijk

  I've enjoyed a number of (fiction/non-fiction books) about hacker culture and running a software business in the 80's, 90's. For some reason things seemed so much more exciting back then. Examples are: Microserfs (Douglas Coupland) Accidental Empires (Robert X. Cringely Almost Pefect (W.E. Peterson, online!) Coders at Work (Peter Seibel) Today I'm an entrepeneur and programmer. Back in the 80's a I was a young geek hacking DOS TSR's and coding GWBasic / QBasic. In the 90's I was a C.S. university student, experiencing the rise of the Internet world wide. When reading these books running a software business seemed so much more fun than it is nowadays. Things used to be so much simpler, opportunities seemed to be everywhere and the startups seemed to work with much more real problems (inventing spreadsheets, writing word processors in assembly on 6 different platforms) than all our current web 2.0 social networking toys. Does anyone share these feelings? Does anyone have any good (personal) stories from back then or know of other good books to read?
