  • Using .add() on the same widget more than once

    - by Dillon Gilmore
    I asked this question on Reddit and was directed here. http://www.reddit.com/r/Ubuntu/comments/vhadl/quickly_dynamic_ui/ Unfortunately I am having the same issue and the problems seems that you can only use .add() on a widget once. So here is my code, self.ui.labels = [] for titles in entries: label = Gtk.Label() self.ui.labels.append(label) self.ui.viewport1.add(self.ui.labels[-1]) self.ui.paned1.show_all() Now, for fun I decided "What would happen if I just manually did..." self.ui.viewport1.add(Gtk.Label()) self.ui.viewport1.add(Gtk.Button()) self.ui.viewport1.add(Gtk.Entry()) For my first code snippet I get this error, Gtk-CRITICAL **: gtk_viewport_add: assertion gtk_bin_get_child (bin) == NULL' failed The error happens an unknown amount of times because the list entries can vary in length, but for my second code snippet it happens exactly twice. This means that when I viewport1.add() it works the first time, but all adds after that receive the error above. So my question, is there a way in python to use .add() on the same widget more than once?

  • Chapter One - Concepts/Requirements (The Fundamentals)

    - by drsql
    So here we are, the starting chapter with the obligatory introductory material that I hope people will read, digest, memorize and really take to heart.  I also realize that that is pretty unlikely. In fact, the first two chapters are kind of like that. First I introduce concepts, and in the next chapter I show how to draw pretty pictures of those concepts. Then comes normalization and after that we really start doing some modeling. In this chapter I am going to cover the basic stuff that you...(read more)

  • How do I know if I am using Scrum methodologies?

    - by Jake
    When I first started at my current job, my purpose was to rewrite a massive excel-VBA workbook-application to C# Winforms because it was thought that the new C# app will fix all existing problems and have all the new features for a perfect world. If it were a direct port, in theory it would be easy as i just need to go through all the formulas, conditional formatting, validations, VBA etc. to understand it. However, that was not the case. Many of the new features are tightly dependant on business logic which I am unfamiliar with. As a solo programmer, the first year was spent solely on deciphering the excel workbook and writing the C# app. In theory, I had the business people to "help" me specify requirements, how GUI looks and work, and testing of the app etc; but in practice it is like a contant tsunami of feature creep. At the beginning of the second year I managed to convince the management that this is not going anywhere. I made them start from scratch with the excel-VBA. I have this "issue log" saved on the network, each time they found something they didn't like about the excel-VBA app, they will write it in there. I check the log daily and consolidate issues (in my mind) mainly into 2 groups: (1) requires massive change. (2) can be fixed in current version. For massive change issues, I make a copy of the latest excel-VBA and give it a new version number, then work on it whenever I can. For current version fixes, I make the changes in a few days to a week, and then immediately release it. I also ensure I update the same change in any in-progress massive change future versions. This has gone on for about 4 months and I feel it works great. I made many releases and solved many real issues, also understood the business logic more and more. However, my boss (non-IT trained) thinks what I am doing are just adhoc changes and that i am not looking at the "bigger picture". I am struggling to convince my boss that this works. So I hope to formalise my approach and maybe borrow a buzzword to confuse him. Incidentally, I read about Agile and SCRUM, about backlog and sprints. But it's all very vague to me still. QUESTION (finally): I want to tell him that this is SCRUM! But I want to hold my breath first and ask whether my current approach is considered SCRUM or SCRUM-like? How can I make it more SCRUM-like? Note that I have only myself, there's no project leader or teams.

  • Learn a language bottom-up or top-down?

    - by Hanno Fietz
    When starting the first project in a new language, you have basically two approaches to learning. Either you do a quick Google search, pull together the most popular frameworks and libraries and work your way from their tutorials towards what you want to achieve (top-down). Or you start with the language basics and the standard library and by and by replace your own simple components with more sophisticated third-party components once you know what you're searching for (bottom-up). Now I'm about to embark on my first serious Javascript project. There's probably as much to know about the language as there is about jQuery, ExtJS and whathaveyou, and I'm trying to decide what to focus on.

  • MS Word Macro in visual Basic

    - by Mac
    I have a Visual Basic system that in places runs word macros. I now need to have a MS Word Macro that I can search for a character and then extend the search to another character and extract the details into a vb variable from the first to the last character. Thereafter I need to search for the next occurrence of the first character and repeat the exercise. When all have been processed the last search must inform me that there are no more. During the searches I need to identify the section numbers where I find the searches and be able to get them in VB variable. Any assistance will be greatly appreciated. Regards Mac

  • JavaOne Content on Video

    - by Tori Wieldt
    JavaOne content is available in video in three sizes, depending on if you want to have a sip, have a drink, or go to the proverbial firehose. Tall (Keynote Highlights) Go to the JavaOne playlist on the YouTube Java channel for highlights of the JavaOne Keynotes.  Grande (Keynotes in Full) Go to the Oracle Media Network JavaOne 2012 channel to view the keynotes in full (Community Keynote coming soon). Venti (All Sessions, BOFs and Tutorials) To view slides paired with audio of each session, go to the JavaOne content catalog (JavaOne homepage > Programs > Content Catalog) and select a session. If a video is available, you'll see "Media" in the right column. Look under "Presentation Download" to get the slides. Sessions are being made available as quickly as possible. "It's exciting to see Oracle take community stewardship so seriously," said Sharat Chander, Group Director for Java Technology Outreach. "Making all JavaOne sessions on video available online for free will helps make the future Java for everyone."

  • Kindle for PC - page loading problems

    - by Andrew Heath
    When viewing books in Kindle for PC, often going to the next page will change the line count at the bottom of the screen but not refresh the page view. Then, if you hit next again, you end up on the next next page (+2 rather than +1). This happens to me going backwards as well. Using arrow keys, or mouse clicks, or page down/up all creates this error. There doesn't seem to be any pattern to the occurrence other than "frequently". It happens on my Win7 64 bit and Win XP machines. I've only one Kindle book at the moment, PHP Object-Oriented Solutions by David Powers, so I suppose it could be a problem specific to that book. Does anyone else have this issue? It is extremely irritating to be constantly flipping back and forth just to get the page view to show the proper page.

  • command line find/replace help

    - by Chrisbloom7
    I've got a set of 5000+ files that I need to do a simple search and replace in. I have been doing it in a text editor (EditPlus) by opening 500 files at a time, doing a global search/replace, saving all, closing, etc. But, that's taking literally hours to do and it's boring and tedious and I already have done it once today and need to do it again because all the files got refreshed. Is there a way to do this via the Bash command line? Here's the details: Find onchange="document.location ='/products/view.html/view/'+this.value" Replace it with onchange="alert('Not implemented')" style="display: none" All of the files have a .HTM extension, but they are nested in several sub directories.

  • Hue shift on youtube.com (but not when embedded!)

    - by Mala
    This is easily the oddest problem I've yet had. When I'm on youtube, and I look at a video, the hue is all wrong. Pure red becomes pure blue, and all the other colors shift accordingly. Faces in particular are shades of blue so I call this "avatar mode". Avatar mode happens on any video I view while on youtube.com. BUT, if I view the same video when embedded, colors are fine! EDIT: OS: Gentoo Linux, happens in all browsers

  • Skynet Big Data Demo Using Hexbug Spider Robot, Raspberry Pi, and Java SE Embedded (Part 4)

    - by hinkmond
    Here's the first sign of life of a Hexbug Spider Robot converted to become a Skynet Big Data model T-1. Yes, this is T-1 the precursor to the Cyberdyne Systems T-101 (and you know where that will lead to...) It is demonstrating a heartbeat using a simple Java SE Embedded program to drive it. See: Skynet Model T-1 Heartbeat It's alive!!! Well, almost alive. At least there's a pulse. We'll program more to its actions next, and then finally connect it to Skynet Big Data to do more advanced stuff, like hunt for Sara Connor. Java SE Embedded programming makes it simple to create the first model in the long line of T-XXX robots to take on the world. Raspberry Pi makes connecting it all together on one simple device, easy. Next post, I'll show how the wires are connected to drive the T-1 robot. Hinkmond

  • LightView: JavaFX 2 real-time visualizer for GlassFish

    - by arungupta
    Adam Bien launched LightFish, a light-weight monitoring and visualization application for GlassFish. It comes with a introduction and a screencast to get you started. The tool provides monitoring information about threads and memory (such as heap size, thread count, peak thread count), transactions (commits and rollbacks), HTTP sessions, JDBC sessions, and even "paranormal activity". In a recently released first part of a tri-part article series at OTN, Adam explains how REST services can be exposed as bindable set of properties for JavaFX. The article titled "Enterprise side of JavaFX" shows how a practical combination of REST and JavaFX together. It explains how read-only and dynamic properties can be created. The fine-grained binding model allows clear separation of the view, presentation, and business logic. Read the first part here.

  • Logfile software for making querys, extracting and other operations

    - by Juw
    I have written an app that connects to a server IIS 6 to retrieve information. When doing this i have collected data (phone model etc) and send it to the server with a regular GET HTTP call like this: http://www.myserver.com/getData.php?phonemodel=userphone&appversion=2&id=20 This is logged in the IIS logfiles. I thought of writing my own parser for log files. But why invent the wheel? I´m looking for a software that can read the IIS 6 logfiles. I would like it to be able to do: Extraction - Extract all lines that contains: www.myserver.com/getData Filtering - View all lines where http-code is not 200 Queries - View all lines where phonemodel=iphone Any tips on free software that can help me with this? Thanx in advance!

  • Computer Freezes After GRUB

    - by paulmcg421
    Ok so I've just built my first computer and have got it running, here are the specs: Asus P8Z68-V PCI-E LX Motherboard, Intel Core i5-2500K, Patriot Memory 8GB (2 x 4GB), Viper Xtreme Series PC3-15000 1866MHz CL9 Division 2 Edition Memory (PXD38G1866ELK), Gigabyte ATI Radeon 6850 820MHz 1GB PCI-E HDMI OC Windforce 2x 500w Ezcool 24pin psu as standard. The only thing I haven't bought new is the hard drive, it's a 250gb that I removed from an Acer Aspire M5100 that I was using till now with no OS Problems. On start up it runs fine but is unresponsive after the GRUB menu disappears to load Ubuntu (Oneric Ocelot). The keyboard lights then turn off and the screen eventually returns that there is no signal. Is there anything that I could be missing from building? (This is my first attempt at building my own PC) Any input would be appreciated, thanks !

    - by Mixhael
    This started to happen immediately after I had rebooted the first time after doing a system upgrade to 12.04 from 11.10. It first starts with a dialogue that says "System program problem detected". Then when I try to hit 'report problem' not much happens. I am led through a dialogue that always ends up the problem cannot be solved. I am running a MacBook1,1 I am aware this is not a lot of information, however I'm not sure which information I need to publish and how should I obtain it to debug this problem. Here's a screenshot!

  • How do you repair an "input/output error" in an NTFS partition?

    - by Calixte
    I replaced a buggy Windows Vista installation with Ubuntu. All works fine except that the mais harddrive where I had all my files are now inaccessible. Here is the eror message I get: Error mounting: mount exited with exit code 13: ntfs_attr_pread_i: ntfs_pread failed: Input/output error Failed to read NTFS $Bitmap: Input/output error NTFS is either inconsistent, or there is a hardware fault, or it's a SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows then reboot into Windows twice. The usage of the /f parameter is very important! If the device is a SoftRAID/FakeRAID then first activate it and mount a different device under the /dev/mapper/ directory, (e.g. /dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation for more details Is it necessarily a hardware problem? If not, is there a way to repair the HD from Ubuntu?

  • Coding events. What they actually are about, and are they worth it?

    - by BKC
    I'm a relatively new programmer, but am very much interested in it. I enrolled to this coding event (Yahoo! Hack India, to be precise), and got invited after the pre-coding contest. The event is like a contest where developers create an application in 24 hours, In group or individually. I've never been to such an event before, and certainly don't know anyone who did. So, here are my questions. First of all, is it worth it? What if we don't get any ideas in the first place to start with? I'm not actually a developer, I'm an electrical engineering student who just completed his 2nd semester. So will be able to match up to the level of other developers who will be there? Any other advice/suggestions Thank you in advance.

  • Server speed: sharing one script.php or using many copies the same script.php

    - by Marco Demaio
    Let's assume: I have thousands of domains on same Apache server. Each domain is in a folder under server public_html document folder, so it can be accessed by calling "www.somedomain.com" or by calling "www.serverdomain.com/somedomain_folder" In each domain there is a website who needs a certain script.php (identical for each domain). From a coding point view, its obvious that it's better to use a unique script.php, so when i update it with new features/bug fixes etc, I need to update on server only one file and it will work for all domains. But from a server point of view? If i use a unique script all domains will access it at the same time, will the server run slower compared to the situation where each domain called its own script?

  • ASP.NET MVVM Handling multiple Data Transfer Objects on a single page

    - by meffect
    I have an asp.net mvc "edit" page which allows the user to make edits to the parent entity, and then also "create" child entities on the same page. Note: I'm making these data transfer objects up. public class CustomerViewModel { public int Id { get; set; } public Byte[] Timestamp { get; set; } public string CustomerName { get; set; } public etc.. public CustomerOrderCreateViewModel CustomerOrderCreateViewModel { get; set; } } In my view I have two html form's. One for Customer "edit" Http Posts, and the other for CustomerOrder "create" Http Posts. In the view page, I load the CustomerOrder "create" form in using: <div id="CustomerOrderCreate"> @Html.Partial("Vendor/_CustomerOrderCreatePartial", Model.CustomerOrderCreateViewModel) </div> The CustomerOrder html form action posts to a different controller HttpPost ActionResult than the Customer "edit" Action Result. My concern is this, on the CustomerOrder controller, in the HttpPost ActionResult [HttpPost] public ActionResult Create(CustomerOrderCreateViewModel vm) { if (!ModelState.IsValid) { return [What Do I Return Here] } ...[Persist to database code]... } I don't know what to return if the model state isn't valid. Right now it's not a problem, because jquery unobtrusive validation handles validation on the client. But what if I need more complex validation (ie: the server needs to handle the validation).
