• What caused you to stop using UML tools on your team?

  - by jamie

  There seems to be plenty of good, free UML tools. I hear about UML tools being used by large organizations, and they seem to have plenty of advocates. However, in my career I have never seen them used beyond "dabbling". Now, I have seen many UML diagrams drawn on whiteboards, and I use them myself all the time, on paper, to think about problems. I've also seen articles such as this one claiming why developers don't use UML, but the arguments just don't land with me. Frankly, this seems like an opportunity for a start-up if one can figure out why developers really don't use them, and solve those problems. So I'm asking anyone here who has attempted to use UML tools in a team, and stopped, this question: "why did you stop?" I'm especially interested in experience from agile teams. I am looking for concrete experience, not hypothetical opinion. Thanks.

• How do you dual boot Windows 7/8 seperatly with GRUB?

  - by Aaron

  I installed the beta version of Windows 8 and re-installed GRUB. When I boot my computer and select Windows 7, I get the new Windows 8 booting screen asking to boot between either Windows 7 or 8. If I choose Windows 7, my computer then restarts and I have to select Windows 7 again in order to boot into 7. But if I choose Windows 8 it boots right up. I understand I can choose which OS to boot by default, but I want my GRUB options to be the only way to choose between OS's. So my question is, how can I set this up so that when I click on Windows 7, I go there, and when I select Windows 8, I boot 8?

• Crappy school, what to do? [closed]

  - by zhenka

  I started programming fairly late. I am 24 years old and about to graduate from a local public university with a really poorly designed curriculum and teachers. Most of the work felt like busy work, and no matter how much I try, it all feels like a waste. I know what a good curriculum looks like. I know what books I should read, but alas it's not so in my university. There is no way at this point that I can catch up to those graduating from places like MIT. My question and this is a serious one: what do I do? Do I just postpone learning the theory I would have learned until later and focus on software engineering skills? How important is the theory in terms of landing a job in New York? Any particular things I should focus on to land a software engineer job? I am very motivated and I just wish someone would give me the time and a chance.

• How to secure Ubuntu for a non-technical user? (your mom)

  - by Gil

  My mother will be traveling for a while and I need to provide her with a secure laptop so she can work. A windows laptop is out of the question because: she'll be logging into dodgy hotel wireless networks and conference networks price of the windows license to install on a netbook I've installed libreoffice, media players and skype on it. Also enabled SSH so I can intervene but I am worried that I might not be in a position to do so. Possible threats: web browsing USB sticks insecure networks prone to intrusions malware SSH/VNC vulnerabilites Skype vulnerabilities All the "securing Ubuntu" guides out there assume the user has a certain level of technical knowledge but this is not the case with moms in general. If a malware can gain even user level access it might compromise her files.

• Generating Wrappers for REST APIs

  - by Kyle

  Would it be feasible to generate wrappers for REST APIs? An earlier question asked about machine readable descriptions of RESTful services addressed how we could write (and then read) API specifications in a standardized way which would lend itself well to generated wrappers. Could a first pass parser generate a decent wrapper that human intervention could fix up? Perhaps the first pass wouldn't be consistent, but would remove a lot of the grunt work and make it easy to flesh out the rest of the API and types. What would need to be considered? What's stopping people from doing this? Has it already been done and my google fu is weak for the day?

• SEO: Joomla Category Page Optimization + Canonical Linking

  - by Huberis

  I'm wondering how best to optimize my Joomla site's SEO. I have pages with multiple articles on each page. Either via category-type pages, or via modules. In each case, I'm not wanting users to access the articles separately from the forward facing, menu-linked pages. I understand however that Joomla still generates a url for those articles, and Google can still crawl and display these articles separate from the pages. My question is what is the best way to control this so that my users get directed only to the front-facing pages? By using the canonical element for each article to point to the front-facing page it's on? Or is there a better method? Thanks for your help!

• Search the internet for a term selected in a text editor/viewer

  - by cipricus

  It seems possible (as I learned from a comment to this question made by user55822) to use Artha in order to search a term on the Internet by using "keybinding". What the aforementioned user says is that "you could search mouse selection anywhere by using an app like Artha, or by keybinding sh -c 'firefox "http://translate.google.com/#en/fr/$(xclip -o)"' (example given translate english into french)" A lot of things are obscure for me here. I could use Artha or keybinding (as alternative), or both? How to do that in each case? and "The command I gave you will open google translate in Firefox with your mouse selection (text highlighted) as a query. Use sh -c 'firefox "https://www.google.com/search?q=$(xclip -o)"' if you want regular Google over Google translate. And obviously, that would work everywhere" I do not know what to do with that formula. What should I do exactly? How to use it? In what application?

• What is this chargeback scam? [on hold]

  - by Dan Friedman

  We have a scammer that is buying our e-Books and then performing chargebacks. Our e-Books don't have DRM, so if they wanted to resell them, they would only need to buy each book once. But instead, they keep buying the same books over and over again and then performing hundreds of chargebacks. We have created some additional rules in our fraud protection tools to block certain aspects, even though all the info looks legit, and are hopeful this will slow them down. But my question is: What is the scam? If they aren't getting any product and they only get chargebacks for something they already purchased, then they can't get additional money from the credit card company, so then what's their motivation?

• What is the concept behind writing a cancel operation in c++?

  - by ToMan

  I'm attempting to write a cancel operation for a software download application. This application will first transfer the software to the device and then install the software on it. (These are givens I'm not allowed to change). What should the cancel operation do? When a user presses 'cancel', the application should stop transferring/installing the software immediately. Question: Since I've never written a "cancel" function, I'm wondering what are the types of things to consider when writing the code, and what are the common bugs I should expect and how to deal with them? Couldn't find anything in google so if you have some links that would be good reads I'd really appreciate it since I'm not looking for answers I'm just looking for guidelines/macro/concept help

• Which folders need to be backedup for migration in Joomla?

  - by Devdatta Tengshe

  I have never used Joomla before, so this might be a noobish question. I have tried searching, but haven't found anything relevant. I'm helping someone update & migrate their old website, built on the Joomla framework. Currently it is running on Joomla 1.5.8 which is an ancient version. I've convinced them to upgrade Joomla to atleast 2.5 I have already taken the database backup. Most links I have seen talk of backing up the entire public_html folder (The website runs on a shared host). But in my fresh Joomla installation there are several folders that are in the public_html folder. So which of the folders in the public_html folder are from the content of the website, and which are of the old Joomla framework? I'm afraid that I might overwrite files of the new Joomla framework with the old framework, if copy all the files and folders into the new installation.

• How do I convert matrices intended for OpenGL to be compatible for DirectX?

  - by gardian06

  I have finished working through the book "Game Physics Engine Development 2nd Ed" by Millington, and have got it working, but I want to adapt it to work with DirectX. I understand that D3D9+ has the option to use either left handed, or right handed convention, but I am unsure about how to return my matrices to be usable by D3D. The source code gives returning OpenGL column major matrices (the transpose of the working transform matrix shown below), but DirectX is row major. For those unfamiliar for the organization of the matrices used in the book: [r11 r12 r13 t1] [r21 r22 r23 t2] [r31 r32 r33 t3] [ 0 0 0 1] r## meaning the value of that element in the rotation matrix, and t# meaning the translation value. So the question in short is: How do I convert the matrix above to be easily usable by D3D? All of the documentation that I have found simply states that D3D is row major, but not where to put what elements so that it is usable by D3D in terms of rotation, and translation elements.

• Can you shade a specific section of a sprite? If so, how? [Java]

  - by l5p4ngl312

  I have been working on an isometric minecraft-esque game engine for a strategy game I plan on making. As you can see, it really needs some sort of shading. It is difficult to distinguish between separate elevations when the camera is facing away from the slope because everything is the same shade. So my question is: can I shade just a specific section of a sprite? All of those blocks are just sprites, so if I shaded the entire image, it would shade the whole block. I am using LWJGL. Heres a link to a screenshot from the engine: http://i44.tinypic.com/qxqlix.jpg

• How-To: AutoVue Bug Status Tracking & Email Notifications

  - by Graham McKendry

  I’ve posted a number of different Support process-related and tool-related blog entries over the past few years, and one common question I received back from various customers and partners is “How can I easily track AutoVue bugs & enhancements for status updates?” The capability to track bug status through the My Oracle Support (MOS) portal has existed in different forms for a while, although hasn’t necessarily been easy to find without going through specific segments of the extensive MOS training. Recently, the instructions were consolidated into the following highly recommended knowledge base article: KM Note 1298390.1 - How to Monitor a Bug from My Oracle Support The note covers various capabilities, including: How to add the new ‘Bug Tracker’ widget to your MOS dashboard How to add and manage bugs within the Bug Tracker and probably most interesting to MOS users... How to enable email notifications for bug status updates Make sure to pass this KM Note along to your MOS users in case they haven’t already configured this valuable feature.

• Do you want to be an officially certified Oracle ADF Developer?

  - by Grant Ronald

  We have just released an official certification exam for Oracle ADF Development.  This exam is aimed that those who are already getting hands-on with ADF and would like an official certification of their development skills. I was involved in writing some of the exam questions and this was an interesting experience.  We were looking to test not only a knowledge of the framework, but also a practical application of that knowledge.  Trying to do that in a clear question which related to multiple choice questions was sometimes difficult but I think we’ve produced a testing exam which, if you pass, shows a strong practical knowledge of ADF. Enjoy!

• How to apply a filter to the screen of a running program?

  - by Shahbaz

  The idea is to take old games without modifying them, but have the graphics card apply a series of filters to their output before sending them to the monitor. A very crude example would be to take a game that has a resolution of 640x480 and do: Increase the resolution to 1280x960 Apply a blur (low pass filter) Apply a sharpen (1 + high pass filter) These steps may not necessarily be the best to improve the visuals of an old game, but there are a lot of techniques that are well-known in image processing for this purpose. The question is, do the (NVidia) graphics cards give the ability to load a program that modifies the screen before sending it to the monitor? If so, how are they called and what terminology should I use to search? I would be comfortable with doing the programming myself if this ability is part of a library. Also, would the solution be different between Windows and Linux? If so, either is fine, since most of the games are probably runnable by wine.

• How to give parallax backgrounds more depth

  - by user28015

  I have 3 tiled images of some sort of galaxy/space in the background of a 2D Game: The first one has an alpha of 100%, the second an alpha of 80% and the last one has an alpha of 60%. I scroll the the one in the background slower than the other ones of course. classic parallax. In the foreground I have some particles flying towards the player to simulate some dust / stars flying by. (I know that stars don't fly by, but I think we all have seen this in a lot of games). But I can't quite achieve the depth effect I am looking for. I want it to look "deeper". I did read something about using blending modes for the backgrounds, but that would require to render them as objects right? So the question is: What is a good technique to do a scrolling parallax background in GameMaker?

• Recovery from hell - undeleting partition overwritten by Xubuntu 12.10 installer?

  - by DaimyoKirby

  This is turning into a nightmare - following my initial recovery of my two partitions, I went to install Xubuntu 12.10 (again). At this time I had two partitions - one of ~39 GB had Zorin OS 6 installed on it, and another of ~33 GB had nothing installed, just a few files in it that I had manually backed up (moved) there. When I got to the partitioning step, I chose "Replace Zorin OS 6 with Xubuntu 12.10", along with LVM, naturally thinking that the installer wouldn't touch the second partition, since Zorin wasn't installed on it. I was dead wrong. Upon booting my newly installed Xubuntu 12.10, I found in gparted that there were only two partitions - ~255MB, which appears to have the boot stuff in it (it's flagged boot in gparted), and another of ~74 GB. Question: Is there any way to salvage my old files on the non-Zorin ext3 partition? I'm really upset I made such a dumb move (again...), and any and all help is appreciated very, very much!

• New to iPhone Development - iOS5 Storyboard

  - by Peter

  I'm new here and pretty new to iOS development. My question is basically, should I learn the old school development methods or just learn how to do things using the latest tools (i.e. Storyboard)? I've had a go with the Storyboard feature of XCode 4.2 and it's very powerful. My only concern is that it requires iOS 5. I don't mind learning the old way of doing things but I've been having trouble finding tutorials/examples for XCode 4.2 that don't use the storyboard. An example would be the with my trouble finding a good tutorial on how to embed a Navigation Controller into a TabBarController. A lot of the material out there seems to be for older version of XCode. Using the storyboard I'm able to set this up with seconds but still haven't managed to get it working without it. So in short :) would you guys suggest I continue my project using the Storyboard or make the extra effort to do things a little more manually?

• How to properly shield a Product Owner from outside?

  - by xsAce

  Update: We are a very small team (3 people) and thus I (Scrum Master) and the Product Owner are also developers doing some coding. We are aware of this situation and we are actively trying to recruit some new talents. But it's hard! Meanwhile... we need to adapt... so my question: The Product Owner complains about having too much outside noise (mainly stakeholders feature requests), and he can't focus on the sprint realisation. We agree that we should try to educate people on our process implications (sprint durations and product backlog), to reduce the noise. But as a Scrum Master, how am I supposed to shield a PO from outside? Isn't he supposed to be in contact with the management and business? Also, if people outside don't want to waste too much time learning agile, what is the best way to educate them?

• Who uses GnuSTEP?

  - by adib

  This has been a big question lurking at the back of my head. From what I see, GnuSTEP nowadays is primarily a "hobby" project of a small but tightly-knit group of people. However I haven't seen a large commercial (off-the-shelf) application that uses it, apart from the small applications that comes with the GnuSTEP distribution. Heck, since even Ubuntu doesn't really use it then is GnuSTEP really more than being a "hobby" framework? I know that Sony's SNAP at one brief moment uses GnuSTEP, but they killed the platform before it can do anything meaningful.

• How Do Search Engines Rank Combined Keywords?

  - by Itai

  Suppose: A site that ranks very well (1st result) for something like 'best blue widget'. It also ranks very well (1st page) for 'blue widget'. It ranks not so well (2nd page) for 'widget'. Obviously, the number of monthly searches are much higher for 'widget' than for 'blue widget', which is still higher than for 'best blue widget'. Now the actual question: When creating new external links, how does each of the following anchor texts affect SEO for of these searches? widget blue widget best blue widget [HINT: The answer should be a 3x3 table] [NOTE: Assume the site is relevant for all these keyword combination]

• Dealing with technical debt

  - by Desolate Planet

  This is a question that I often ask myself when working with developers. I've worked at four companies so far, and I've noticed a lack of attention to keeping code clean and dealing with technical debt that hinders future progress in a software app. For example, the first company I worked for had written a database from scratch rather than take something like MySQL and that created hell for the team when refacoring or extending the app. I've always tried to be honest and clear with my manager when he discusses projections, but management doesn't seem interested in fixing what's already there and it's horrible to see the impact it has on team morale and in their attitude towards others. What are your thoughts on the best way to tackle this problem? What I've seen is people packing up and leaving and the company becomes a revolving door with developers coming and and out and making the code worse. How do you communicate this to management to get them interested in sorting out technical debt?

• Google indexed site's address by accident. What do I do now?

  - by AndrejaKo

  I was making a site for a friend of mine and he wanted to be able to see my progress as I worked on the site, so I decided to put the site on a server on my computer and enable access by a domain name registered to me. It turns out that I forgot to set up a robots.txt file for the site and somehow Google indexed the site. My question is: What do I do now? As I understand it, Google doesn't like duplicate content and my friend could have problems when I upload the new site to his server. Right now his current site, which only has a work in progress page, is first on Google when searching for relevant keywords and I really really don't want to damage that. Is there anything else I need to be concerned about?
