• Help building pygtk application

  - by umpirsky

  This is my application. It is created with quickly. I would like to package it for Ubuntu now. I tried to package it with uickly, but that failed. At first, I was trying to install it using setup.py. But it is only copied in python lib dir, no icon, no desktop file installed. Then I tried to follow this guide, but I ended up with package without icon and it was of bad quality, but most important of all, it does not use setup.py, and it was pretty complicated. I would like to automate packaging process Can someone point me in the right direction, some examples of existing apps that have automated packaging etc? Thanks in advance.

• Should I forward the a call to .Equals onto .Equals<T>?

  - by Jaimal Chohan

  So, I've got you bog standard c# object, overriding Equalsand implementing IEquatable public override int GetHashCode() { return _name.GetHashCode(); } public override bool Equals(object obj) { return Equals(obj as Tag) } #region IEquatable<Tag> Members public bool Equals(Tag other) { if (other == null) return false; else return _name == other._name; } #endregion Now, for some reason, I used to think that forwarding the calls from Equals into Equals was bad, no idea why, perhaps I read it a long time ago, anyway I'd write separate (but logically same) code for each method. Now I think forwarding Equals to Equals is okay, for obvious reasons, but for the life me I can't remember why I thought it wasn't before. Any thoughts?

• Should all, none, or some overriden methods call Super?

  - by JoJo

  When designing a class, how do you decide when all overridden methods should call super or when none of the overridden methods should call super? Also, is it considered bad practice if your code logic requires a mixture of supered and non-supered methods like the Javascript example below? ChildClass = new Class.create(ParentClass, { /** * @Override */ initialize: function($super) { $super(); this.foo = 99; }, /** * @Override */ methodOne: function($super) { $super(); this.foo++; }, /** * @Override */ methodTwo: function($super) { this.foo--; } }); After delving into the iPhone and Android SDKs, I noticed that super must be called on every overridden method, or else the program will crash because something wouldn't get initialized. When deriving from a template/delegate, none of the methods are supered (obviously). So what exactly are these "je ne sais quoi" qualities that determine whether a all, none, or some overriden methods should call super?

• Issues with Dz77BH-55K Motherboard and i7 processor on 12.04

  - by Naveed

  I just built a computer with Intel's DZ77BH-55K motherboard with i7-3770 processor. On 12.04, 11.10, and 11.04 and Linux Mint 12, the computer has been really laggy. The graphics aren't working (choppy effects, bad resolution) and the keyboard and mouse inputs are even laggy and unreliable (skips keystrokes). I'm not sure what the problem is or what I can do to fix it. I tried sudo apt-get install mesa-utils but nothing changed. I've also messed around in the BIOS but no luck there either. Any ideas? Could it possibly be a hardware issue?

• What You Said: Your Favorite Remote Desktop Access Tools and Tips

  - by Jason Fitzpatrick

  Earlier this week we asked you to share your favorite remote desktop access tools and tips; now we’re back to highlight your favorite tools and how you use them. The two prevailing themes among all the tools suggested were pricing and ease of deployment. On that front, LogMeIn had a strong following. Mtech writes: I use Logmein and am amazed the free version can be used even for business purposes. I also felt so bad and wanted to pay for the Pro version just out of gratitude but they called me personally from the USA and said why pay when the free version does all you need! What a company.

• Is SVN out of style?

  - by jitbit

  It's been only several years since I migrated from Visual Source Safe to SVN. And SVN for me is still kinda "WOW! I can do so many things! SVN is so cool!" But many people around me keep saying "SVN? Really? Meh..." And there's so many of them that I'm worried. Should I move my team to Git / Mercurial or some other fancy thing? I know I sound ridiculous and the obvious answer would be "stay with what works for YOU". SVN does work for me... But every time I create a new project in my repository I keep asking myself - may be this was the time to move? So... Is SVN really that bad? Do I miss a huge opportunity by sticking with it?

• failure to restore backup from deja dup

  - by Layla Kosakov

  I had ubuntu 12.04.1 and I made a backup with deja dup of the home folder in an external hard disk. Today I installed ubuntu 14.4 and erased the ubuntu 12.04.1. Now I'm trying to restore my back up. First it ask where is the back up to restore, then it ask of what date to restore, and then it starts, after a wile ask for the password. I put the password and it says Restoring and stays in preparing with out any advancement. Don't show any error, just stays preparing. The window of details is in white. I had all my documents... it's very bad for me, all my personal data... lost? Thanks for any help, Layla.

• Adding unit tests to a legacy, plain C project

  - by Groo

  The title says it all. My company is reusing a legacy firmware project for a microcontroller device, written completely in plain C. There are parts which are obviously wrong and need changing, and coming from a C#/TDD background I don't like the idea of randomly refactoring stuff with no tests to assure us that functionality remains unchanged. Also, I've seen that hard to find bugs were introduced in many occasions through slightest changes (which is something which I believe would be fixed if regression testing was used). A lot of care needs to be taken to avoid these mistakes: it's hard to track a bunch of globals around the code. To summarize: How do you add unit tests to existing tightly coupled code before refactoring? What tools do you recommend? (less important, but still nice to know) I am not directly involved in writing this code (my responsibility is an app which will interact with the device in various ways), but it would be bad if good programming principles were left behind if there was a chance they could be used.

• large product image structured data and visibility

  - by Mark Resølved

  On an eCommerce site we two images for a product. One medium sized shown on top of the page and one large photo shown on click in an overlay. We use http://schema.org/Product microdata on the page. We'd like the large, initially hidden, photo to be the main image for the product, as it's the better looking one. So it's also referenced in the XML sitemap as <image:image>. So we also put the itemprop"image" attribute on the, hidden large image. But i'm wondering is it a bad idea to use a microdata attribute on a hidden style="display:none;" element? is there a better way to embed the main image in terms of SEO, without showing it initially?

• Tracking Redirects Leading to your site

  - by Bill

  Is there a way in which I can find out if a user arrived at my site via a redirect? Here's an example: There are two sites, first.com & second.com. Any request to first.com will do a 302 redirect to second.com. When the request at second.com arrives, is there anyway to know it was redirected from first.com? Note that in this example you have no control over first.com. (In fact, it could be something bad, like kiddieporn.com.) Also note, because it is a redirect, it will not be in the HTTP referrer header.

• Rendering problems with Java LWJGL

  - by pangaea

  I'm new to rendering and so I don't know if I can speed up the code or that what I'm doing is bad. This is what it looks like But, if I have say 100-200 triangles everything is fine. Yet, when I get to 400 triangles it becomes very laggy. At 1,000 triangles it becomes 5fps at max. Also, when I try to close it everything becomes extremely laggy and the game breaks my computer. Is this normal? The code is here http://pastebin.com/9N6qdEbd game http://pastebin.com/fdkSrPGT mobs I haven't even adding collision detection.

• Cost of maintenance depending on paradigms

  - by Anto

  Is there any data on which paradigms allow for code which is easier/cheaper to maintain? Certainly, independantly of the chosen paradigm, good design is cheaper to maintain than bad, but there should probably be major differences coming only from the paradigm choice. Unstructured programming, for instance, generates very messy code (spaghetti code) which is expensive to maintain. In object oriented programming, implementation details are hidden and thus it should be pretty cheap to change those. In functional programming, there are no side effects, thus there is lesser risk of introducing bugs during maintainance, which should be cheaper. Is there any data on which paradigms are the most cost-efficient when coming down to maintenance? If no such data exists, what is your take on the question?

• Which specific practices could be called "software craftsmanship" rather than "software engineering"?

  - by FinnNk

  Although not a new idea there seems to have been a big increase in the interest in software craftsmanship over the last couple of years (notably the often recommended book Clean Code's full title is Clean Code: A Handbook of Agile Software Craftsmanship). Personally I see software craftsmanship as good software engineering with an added interest in ensuring that the end result is a joy to work with (both as an end user and as someone maintaining that software) - and also that its focus is more at the coding level of things than the higher level process things. To draw an analogy - there were lots of buildings constructed in the 50s and 60s in a very modern style which took very little account of the people who would be living in them or how those buildings would age over time. Many of those buildings rapidly developed into slums or have been demolished long before their expected lifespans. I'm sure most developers with a few years under their belts will have experienced similar codebases. What are the specific things that a software craftsman might do that a software engineer (possibly a bad one) might not?

• Panda 4: Reducing #indexed pages. How much is enough?

  - by Noam

  I've been hit by panda 4 (40% decrease). I didn't see any change during panda 1-3. From what I've read it and when compared to my site, the change is probably due to the fact that I have over 30M pages indexed on Google, and they've starting seeing that as some sort of bad indication. Although I feel all of the pages have a unique value that Google should crawl, it seems I should make some tough calls and deduce the indexed pages according to some prioritization I will conduct. The question is what should be my target, or what factors should help me figure out a relevant target. How many pages should I try to reduce to? - 25M - 15M - 1M - 2000 Is it enough to add noindex to low priority pages or should I also remove all internal linking to them?

• 'Situations gone wrong' for web apps...

  - by AvgJoe007

  Hi all I know there's some decent material floating around relating to more specific areas, but wanted to get some opinions from people who have had bad experiences in the past. I have a project where I can have a say on the design of a B2C web app, which has some external API interfaces. UX is crucial as is speed. Not sure what technology will be used at this stage. In designing this application, I want to make sure obvious features are not left out (i.e. ones that make maintenance/development easier). So can you guys tell me about 'situations gone wrong' that could have been avoided had more consideration taken place? Am looking to gather feedback in general, so don't worry if your example is industry/technology specific - so long as it pertains to web. Thanks for reading, I look forward to your responses!

• Has anyone used Sproutcore?

  - by Sam Lee

  Has anyone used Sproutcore for a web application? If so, can you give me a description of your experience? I am currently considering it, but I have a few concerns. First, the documentation is bad/incomplete, and I'm afraid that I'll spend lots of time figuring things out or digging through source code. Also, I'm a bit hesitant to use a project that is relatively new and could undergo significant changes. Any thoughts from people who have developed in Sproutcore are appreciated! EDIT/PS: Yes, I've seen this post: http://stackoverflow.com/questions/370598/sproutcore-and-cappuccino . However I'm interested in a bit lengthier description of Sproutcore itself from someone who's used it for a significant project.

• How to survive if you can only do things your way as a programmer?

  - by niceguyjava

  I hate hibernate, I hate spring and I am the kind of programmer who likes to do things his way. I hate micro-management and other people making decisions for me about what framework I should use, what patterns I should apply (hate patterns too) and what architecture I should design. I consider myself a successful programmer and have a descent financial situation due to my performance in past jobs, but I just can't take the standard Java jobs out there. I really love to design things from scratch and hate when I have to maintain other people's bad code, design and architecture, which is the majority you find out there for sure. Does anybody relate to that? What do you guys recommend me? Open up my on company, do consulting, or just keep looking hard until I find a job that suits my preferences, as hard as this may look like with all the hibernate and spring crap out there?

• How do you organize your projects?

  - by Sergio

  Do you have any particular style of organizing projects? For example, currently I'm creating a project for a couple of schools here in Bolivia, this is how I organized it: TutoMentor (Solution) TutoMentor.UI (Winforms project) TutoMentor.Data (Class library project) How exactly do you organize your project? Do you have an example of something you organized and are proud of? Can you share a screenshot of the Solution pane? In the UI area of my application, I'm having trouble deciding on a good schema to organize different forms and where they belong. Edit: What about organizing different forms in the .UI project? Where/how should I group different form? Putting them all in root level of the project is a bad idea.

• How to fix Xubuntu LightDM Theme after installing unity.

  - by Christopher

  After successfully installing Xubuntu 12.04.1 on my laptop, I decided to install Unity. That went OK but then I realized there was no themes. So then I installed the themes and artwork, and got a really bad surprise. My lightDM greeter was still Xubuntu like I wanted but the buttons where you choose the user are really tall and I have a purple computer as the icon above my computer name. How do I get back to the original Xubuntu configuration or edit the CSS while keeping Unity? I know where all of the files are but don't know which file to edit or which CSS property to modify. Packages Installed: unity unity-services unity-mail Then I Installed: ubuntu-artwork light-themes ubuntu-wallpapers-oneric ubuntu-wallpapers-precise

• How many hours can you be really productive per day? How?

  - by fzwo

  I find that I'm having a great deal of trouble staying alert 8 hours per day. I've heard of people who've negotiated work contracts of just 4 hours/day, arguing that they won't be able to do much more in eight hours. I am often overwhelmed with drowsiness, boredom, distraction. Some days, I seem to blaze through eight hours in a furious explosion of productivity; other days, I hardly get anything done at all. Most days, it's somewhere in between, and I feel bad for wasting a lot of time because I can't muster the concentration to be my best throughout much of the day. I'd like to hear your experiences (tell me I'm not alone!), and, if found, your solutions to this dilemma. Are you productive 8 hours/day almost every day? How?

• How do I install xulrunner in 12.04?

  - by chessplayer

  I am trying to migrate a virtual machine I use for my classes at the university from 10.04 to 12.04 and in that I am using xulrunner so that first, I can have SQLiteManager as a stand alone app next, KNIME can provide help for its nodes I tried adding the the mozilla ppa as described in some posts, e.g. here or here, but when I search for xulrunner in Synaptic I get no match. I read in this link, that xulrunner was left out intentionally, which, frankly, I think is a bad decision! Anyway, does anyone know a way out of this, i.e. how to get xulrunner for 12.04? Any help appreciated!
