Getting mybrother MFC-J825DW working as a network scanner

- by AntonChanning

I've been attempting to set up my new brother multi-function device to work as a printer and scanner using the following steps. It is connected to the network as a LAN device, not directly connected to my ubuntu machine. Downloaded the lpr driver and cupswrapper driver from Brother support. (Select the deb packages, not the rpms). Followed the instructions to install the lpr driver. Followed the instructions to install the cupswrapper driver. After this point I was able to successfully perform a test print, so the printer part is working. So far I haven't had much luck getting the scanner working. This is what I've tried: Downloaded the brscan4 and scan-key-tool deb packages from brother support. Followed the instructions for installing the scanner driver for network. Followed the instructions for installing scan-key-tool. However when I tried to scan it detects no scanner. I then tried the solution offered in this answer to a question based on a similar brother printer, but no luck. I must have made a mistake somewhere along the line. Does anyone have any ideas what I can try to find out what? Or should I uninstall everything and start again from the beginning?

apply non-hierarchial transforms to hierarchial skeleton?

- by user975135

I use Blender3D, but the answer might not API-exclusive. I have some matrices I need to assign to PoseBones. The resulting pose looks fine when there is no bone hierarchy (parenting) and messed up when there is. I've uploaded an archive with sample blend of the rigged models, text animation importer and a test animation file here: http://www.2shared.com/file/5qUjmnIs/sample_files.html Import the animation by selecting an Armature and running the importer on "sba" file. Do this for both Armatures. This is how I assign the poses in the real (complex) importer: matrix_bases = ... # matrix from file animation_matrix = matrix_basis * pose.bones['mybone'].matrix.copy() pose.bones[bonename].matrix = animation_matrix If I go to edit mode, select all bones and press Alt+P to undo parenting, the Pose looks fine again. The API documentation says the PoseBone.matrix is in "object space", but it seems clear to me from these tests that they are relative to parent bones. Final 4x4 matrix after constraints and drivers are applied (object space) I tried doing something like this: matrix_basis = ... # matrix from file animation_matrix = matrix_basis * (pose.bones['mybone'].matrix.copy() * pose.bones[bonename].bone.parent.matrix_local.copy().inverted()) pose.bones[bonename].matrix = animation_matrix But it looks worse. Experimented with order of operations, no luck with all. For the record, in the old 2.4 API this worked like a charm: matrix_basis = ... # matrix from file animation_matrix = armature.bones['mybone'].matrix['ARMATURESPACE'].copy() * matrix_basis pose.bones[bonename].poseMatrix = animation_matrix pose.update() Link to Blender API ref: http://www.blender.org/documentation/blender_python_api_2_63_17/bpy.types.BlendData.html#bpy.types.BlendData http://www.blender.org/documentation/blender_python_api_2_63_17/bpy.types.PoseBone.html#bpy.types.PoseBone

How can I set up Eclipse to work with a Quickly program?

- by Niklas

I've installed PyDev in Eclipse and have configured my project so that the project lies under Workspace/Eclipse and the Quickly files lies under Workspace/Quickly. To connect the two I've linked the Quickly project by creating a new folder in Eclipse under the project and select the "advanced option" in the dialog to link a folder into the project. That way I don't need to have the Eclipse project files in my Quickly project. But there is two issues that arises for me: In Eclipse I have to select a Python interpreter and I have no idea what to do. I've googled around for an answer but I can't find if Quickly uses Python 3 or 2.7. Can someone help me make an informed choice? (I'm new to developing Python, that's why I can't tell the difference by the syntax - if there even is a difference) I can't press the "Run" button to launch the application. Must I initialize a program with quickly run? I want to be able to debug through Eclipse, how do I configure this? I'm using Ubuntu 12.04.1 LTS and the Eclipse version from the repositories. Thanks!

Unattended grub configuration after kernel upgrade

- by bouke

Today I have been working on automatic deployment of an ubuntu server. I got stuck on automatic updating of the server using apt-get upgrade trying to upgrade to a new kernel. The log looks like this: Setting up linux-image-3.2.0-24-generic (3.2.0-24.39) ... Testing for an existing GRUB menu.lst file ... found: /boot/grub/menu.lst (...) Then a question is presented: Package configuration +---------------------------------¦ +---------------------------------+ ¦ A new version of /boot/grub/menu.lst is available, but the version ¦ ¦ installed currently has been locally modified. ¦ ¦ ¦ ¦ What would you like to do about menu.lst? ¦ ¦ ¦ ¦ install the package maintainer's version ¦ ¦ keep the local version currently installed ¦ ¦ show the differences between the versions ¦ ¦ show a side-by-side difference between the versions ¦ ¦ show a 3-way difference between available versions ¦ ¦ do a 3-way merge between available versions (experimental) ¦ ¦ start a new shell to examine the situation ¦ ¦ ¦ ¦ ¦ ¦ <Ok> ¦ ¦ ¦ +----------------------------------------------------------------------+ The desired outcome would be to select the first option and to continue: Replacing config file /run/grub/menu.lst with new version Updating /boot/grub/menu.lst ... done After running the upgrade by hand, I used debconf-get-selections to inspect the correct answer for the question (see other settings). It seems like update_grub_changeprompt_threeway is the question that should be answered. However, setting this using debconf-set-selections presented me with the same question: debconf-set-selections <<< "grub grub/update_grub_changeprompt_threeway select install_new" apt-get -y dist-upgrade How can this question be automated?

When does a Project Manager start in a project?

- by johndoucette

From a colleague of mine… “As a project manager, when do you typically like to get initially involved in the project? Is it better for the PM to be rolled on during the project kick-off, the first week, or is it better to roll-on the second week when things settle down?” My textbook answer is “the Project Manager is responsible for the successful completion and delivery of the expected outcome of the project through the following major tasks;” 1. Identifying requirements 2. Establishing clear and achievable objectives 3. Balancing the competing demands for quality, scope, time, and cost 4. Adapting the specifications, plans, and approach to the different concerns and expectations of the various stakeholders However; My colleague is often a lead technical consultant coming into a project alone to help a client solve a complex problem. As Magenic consultants, we all possess many of the “project managing” skills I talked about above and tend to be responsible for item #1 and #2 as well as the actual architecture/design tasks early in a project. When the real development begins and there is no PM involved, the project will quickly get harder to execute unless items #3 & #4 are assigned to a Project Manager. In software development, the concept of context switching between coding and other administrative activities is the hardest skill perfect. In my experience, I have rarely been introduced to someone who has mastered this skill. This is the limbo I was in when I was asked to become a PM -- while still developing. “Put down the code” was not only a profound statement, but looking back – a necessary one. Unless you are lucky to have found that one developer who is a superman, asking your developers (internal corporate or consultant) to perform #3 and #4 tasks, will surely take more time, allow opportunity for more scope, and eventually cost more. Project Managers are crucial to the overall success of a project, and I prefer them to start by taking ownership of delivery on day one.

Disallow all user agents except one using .htaccess?

- by Kian Mayne

I've been struggling to get this .htaccess working. The aim is to disallow all user agents besides my app. The app sends a GET request with a user agent of lets say 'AcmeUpdater'. Whenever I try to navigate to any file in the folder, I get a 500 - Internal Server Error. Here are the rules I'm using: <IfModule mod_rewrite.c> Options +FollowSymLinks RewriteEngine on RewriteBase / RewriteCond %{HTTP_USER_AGENT} !^KMUpdaterClient* RewriteRule .* - [F,L] </IfModule> I have updated the .htaccess file as suggested in the answer by Nick, and restarted Apache. After trying a couple of different things, it seems that just the presence of a .htaccess is causing the 500 error. I'm getting nothing in the error logs. The .htaccess file at the document root looks like the following: <IfModule mod_rewrite.c> Options +FollowSymLinks ErrorDocument 404 /index.php?error=404 RewriteEngine On RewriteBase / RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d </IfModule> So I realised that the error logs were in chronological order rather than the reverse chronological I expected (Oops!). The error I'm getting is: </IfModule> without matching <IfModule> section. I removed the </IfModule> and still I get that error. Ideas?

Handling changes to data types and entries in a database migration

- by jandjorgensen

I'm fully redesigning a site that indexes a number of articles with basic search functionality. The previous site was written about a decade ago, and I'm salvaging about 30,000 entries with data stored in less-than-ideal formats. While I'm moving from MSSQL to MySQL, I don't need to make any "live" changes, so this is not a production-level migration issue so much as a redesign. For instance, dates are stored the same as tags/subjects about the articles, but in strings as "YYYYMMDDd" (the lowercase d stands for "date" in the string). Essentially, before or after I move from the previous database format to a new one, I'm going to need to do a lot of replacement of individual entries. While I understand how to do operations with regular expressions in non-database issues, my database experience isn't robust enough to know the best way to handle this. What is the best (or standard) way to handle major changes like this? Is there an SQL operation I should be looking into? Please let me know if the problem isn't clear--I'm not entirely sure what kind of answer I'm looking for.

Second monitor not detected

- by configurator

Note: I've seen this question quite a lot, but in all the cases I could find with answers, the answer was either "I don't know" or "use nvidia-settings (which is irrelevant to me)." I'm using Intel Sandybridge Desktop graphics, with a P8H61-M LE motherboard. How do I get Ubuntu to detect my second monitor? Clicking "Detect Displays" here doesn't do anything.

Need database selection advise

- by jacknad

I know this is considered a bad question since there is no correct answer, but I need to decide on a database for embedded linux (DaVinci 368 based) hardware and I've never had to produce a design with a database before. Each record will probably contain less than 1000 images with associated alpha-numeric data and the mass storage will be some kind of flash drive. Only one user needs access to the data at a time. MySQL claims to be "The world's most popular open source database" but SQLite claims to be "the most widely deployed SQL database engine in the world." Perhaps there is another that is also the best in the world? Which is easiest to use for a database newbie? Should I just flip a coin? Does it really matter which one I pick? Do I even need to use a database software package or should I roll my own? I won't need bells and whistles like sorting, but I'll probably need to delete the oldest records to make room for new ones if the storage fills up.

Should my program "be lenient" in what it accepts and "discard faulty input silently"?

- by romkyns

I was under the impression that by now everyone agrees this maxim was a mistake. But I recently saw this answer which has a "be lenient" comment upvoted 137 times (as of today). In my opinion, the leniency in what browsers accept was the direct cause of the utter mess that HTML and some other web standards were a few years ago, and have only recently begun to properly crystallize out of that mess. The way I see it, being lenient in what you accept will lead to this. The second part of the maxim is "discard faulty input silently, without returning an error message unless this is required by the specification", and this feels borderline offensive. Any programmer who has banged their head on the wall when something fails silently will know what I mean. So, am I completely wrong about this? Should my program be lenient in what it accepts and swallow errors silently? Or am I mis-interpreting what this is supposed to mean? Taken to the extreme, if Excel followed this maxim and I gave it an exe file to open, it would just show a blank spreadsheet without even mentioning that anything went wrong. Is this really a good principle to follow?

Can't add NetworkManager applet to gnome panel

- by Nate

I have researched this problem extensively and I can't seem to find an answer. In Ubuntu 10.04 LTS, I want to connect to my VPN through the NetworkManager applet. I installed all the network manager packages, including the gnome client. I understand I need to add the "Notification Area" to the panel, which I have done. I checked that the NetworkManager is running: nate@nate-desktop:~$ service network-manager status network-manager start/running, process 763 In /etc/NetworkManager/nm-system-settings.conf, I have added managed=true (don't know if this matters, but I saw it suggested on one forum): nate@nate-desktop:~$ more /etc/NetworkManager/nm-system-settings.conf # This file is installed into /etc/NetworkManager, and is loaded by # NetworkManager by default. To override, specify: '--config file' # during NM startup. This can be done by appending to DAEMON_OPTS in # the file: # # /etc/default/NetworkManager # [main] plugins=ifupdown,keyfile [ifupdown] #managed=false managed=true I restarted NetworkManager and tried rebooting, too. At this point, it looks like NetworkManager is running but it's not appearing in the NotificationArea of the panel. I don't know what else to try. Any ideas?

Meta tags again. Good or bad to use them as page content?

2 year degree plus experience vs 4 year degree

- by CenterOrbit

Alright, I have searched around a bit on this site and found two somewhat similar questions: Computer Science Programming Certificate vs. Computer Science Degree? Is it possible/likely to be paid fairly without a college degree? But these do not provide an answer specifically to what I am seeking. I have my 2 year A.A.S. Degree in computer programming, along with a networking certificate from a technical college. I also have been working at a small educational game development company for 3 years now in various positions, but steadily moving up and now as a lead programmer on a few projects. Some of the higher programmers I work with claim that no matter how much experience I develop it still will not mean as much as someone with a 4 year degree. Their argument is that most employers will look over my resume because of the common '4 yr' minimum requirement. I have also heard people state (not as many though) that experience is everything and that an employer would rather have someone that has worked in the field instead of a rookie fresh out of college. I have heard both sides of this argument, but am looking for a general consensus, or more arguments from both sides from the people who have been there, or are there.

eBook editions of programming books

- by Jon Hopkins

(I'll get my justification for why this is on topic in early: programming books tend to have fairly specific formatting needs - code samples, tables, images and graphs - which are not common to all book types and are not necessarily well handled by eBook readers. Similarly they're used in different ways - you often dip in and out rather than read cover to cover.) I've just noticed that Don't Make Me Think by Steve Krug is available as an eBook edition for the Kindle (and presumably also for other readers) which set me thinking. There are certain advantages to eBook readers for tech books - primarily that you can carry a massive library of what would be heavy physical books around very easily. The downside is that certain eBook readers allegedly aren't particularly well equipped to cope with tables, code samples and so on and a book like Don't Make Me Think presumably makes extensive use of these sorts of things. So, the question, what are your experiences of reading and using programming books on an eBook reader and would you recommend it? I'm specifically interested in the latest generation Kindle but happy to hear about all devices - might be useful to state which one you use in the answer.

Is there an established or defined best practice for source control branching between development and production builds?

- by Matthew Patrick Cashatt

Thanks for looking. I struggled in how to phrase my question, so let me give an example in hopes of making more clear what I am after: I currently work on a dev team responsible for maintaining and adding features to a web application. We have a development server and we use source control (TFS). Each day everyone checks in their code and when the code (running on the dev server) passes our QA/QC program, it goes to production. Recently, however, we had a bug in production which required an immediate production fix. The problem was that several of us developers had code checked in that was not ready for production so we had to either quickly complete and QA the code, or roll back everything, undo pending changes, etc. In other words, it was a mess. This made me wonder: Is there an established design pattern that prevents this type of scenario. It seems like there must be some "textbook" answer to this, but I am unsure what that would be. Perhaps a development branch of the code and a "release-ready" or production branch of the code?

UIView vs CCLayer and Making gestures work in Cocos2d

- by Lewis

now I've been been searching for an answer to this question for at least 3 days now. I've tried on many cocos2d forums, including the official one and have heard nothing back. I've found a project which uses custom gestures: https://github.com/melle/OneFingerRotationGestureDemo Explanation here: http://blog.mellenthin.de/archives/2012/02/13/an-one-finger-rotation-gesture-recognizer/ Now I want to implement that behaviour onto a sprite in a cocos2d application. I've tried to do this but it fails to work. It uses a view controller which inherits like this: @interface OneFingerRotationGestureViewController : UIViewController <OneFingerRotationGestureRecognizerDelegate> Now my question is how would I implement the OneFingerRotationGesture behaviour onto a CCSprite in cocos2d 2.0? As interfaces in cocos2d look like this: @interface HelloWorldLayer : CCLayer Now I have asked a similar question to this on stack overflow and a user directed me to this link: https://github.com/krzysztofzablocki/CCNode-SFGestureRecognizers Which I believe makes use of gestures (like the first github linked project) but not custom gestures. I lack the obj-c skills to work out and implement the functionality into my game, so I would appreciate it if someone could explain the differences between CCLayer and UIViewController, and help me implement the OneFingerRotation gesture into a cocos2d 2.0 project. Regards, Lewis.

Installation hangs at "Retrieving file 43 of 105" Virtualbox OS X 10.7 Host Ubuntu 12.04 x86 guest

- by goodcop

This is my second attempt at installing Ubuntu. In my first attempt, I selected "download updates" and "install third-party components"; in my second attempt, I deselected both. Still experiencing the same problem. In my first attempt at installing Ubuntu, after the installation stuck at "Retrieving file 43 of 105", I selected "skip" and the installation completed. After I started to run the OS, I received a notification that language support was incomplete. When I tried to update it, the Ubuntu Software Centre updating process hung on "waiting for jockey-backend to exit", seemingly indefinitely. At that point, I decided to reinstall the system (since the whole process is only supposed to take 45 minutes or less), but, as I mentioned above my results were the same. I'm new to Ubuntu. Any advice? Where are the files (including file 43) being retrieved from? Online or from the ubuntu installation iso? I have searched many forums for an answer to this problem, and have seen others with the same issue but I haven't found a solution. Thanks.

How Many Google +1's Does a Website need in order for Google WebMaster's Tools to Show Characteristics

- by Asaph

I have added the Google +1 Button to my website and discovered the new Social Activity section in Google WebMaster's Tools. Apparently, one of the interesting things you can learn about your audience is demographic data. But in GWT, the Social Activity Audience section for my site (currently 82 +1's), says the following: Your site doesn’t have enough +1's yet to show characteristics But I'm not sure how many +1's is enough. Google's official help page for the Audience section offers little insight: The Audience page displays information about people who have +1'd your pages, including the total number of unique users, their location, and their age and gender. All information is anonymized; Google doesn't share personal information about people who have +1’d your pages. To protect privacy, Google won't display age, gender, or location data unless a certain minimum number of people have +1'd your content. But what is that "certain minimum number"? I've tried Googling this but all I could find to date was this page which doesn't answer the question. So how many +1's does a site need before GWT will show me audience demographic characteristics?

Graphic Card Installation Failure (NV 9600M GT)

- by Georg

I wanted to switch from 7 to Ubuntu. Now, the first thing that holds me back is the installation of the driver for my Nvidia 9600M GT. Ubuntu recommends me 4 drivers from the "Additional Driver" Section. Now, whatever driver I install, there are four things happening RANDOMLY after rebooting: The pc freezes before seeing bootup splash The pc freezes while seeing bootup splash image (ubuntu logo with the 5 dots) The pc gets into login screen and freezes instantly (Thought the unity-bar is transparent now) The pc freezes right after beeing able to login. (While this is happening the unity-bar changes from transparent to ugly-flat-style) I also tried to install the official Nvidia .run file but after exiting the X-Server, it says the driver is not compatible with the kernel and exits installation. Can somebody help me? I really wanna get rid of Windows :( But Ubuntu drives me perfectly insane. Please answer as noobish as possible. I'm an expert Windows user, but Linux is absolutely new to me. My Specs: Ubuntu 11.10 installed from USB Stick (like 100 times now :/ because I dont know how to remove the driver in recovery mode) 9600M GT 4GB Ram Intel Centrino 2 Dual Core 2.26GHz Win 7 and Ubuntu running along side.

I have the following SHA256 wrapper. public static string SHA256(string plainText) { StringBuilder sb = new StringBuilder(); SHA256CryptoServiceProvider provider = new SHA256CryptoServiceProvider(); var hashedBytes = provider.ComputeHash(Encoding.UTF8.GetBytes(plainText)); for (int i = 0; i < hashedBytes.Length; i++) { sb.Append(hashedBytes[i].ToString("x2").ToLower()); } return sb.ToString(); } Do I want to be testing it? If so, what do you recommend? My thought process is as follows: What logic is there here. The answer is my for loop and ToString("x2") so from my understanding I want to be testing this part? I can assume Encoding.UTF8.GetBytes(plainText) works. Correct assumption? I can assume SHA256CryptoServiceProvider.ComputeHash() works. Correct assumption? I want to be only testing my logic. In this case is limited to the printing of hex encoded hash. Correct? Thanks.

Modern techniques for spriting

Hello, I would like to know the flow for making modern 2D game artwork. How are the assets made nowadays? Bitmap? Vector-based? Hand-drawn and painted? Drawn digitally? Modeled in 3D and exported to bitmaps? I would like some information on programs as well, for fine looking art. Why does Flash's vector art style look good in most games? How do I make equivalent graphics with external tools? Or equaly good and not vector-based, anyway. Any special hints for animating? An answer oriented towards a one-man-army indie developer with little experience but some artistic sense would be appreciated! Not a complete dummy with paint programs, but also not a master at all, just need efficient ways to achieve results. Thanks. NOTE: Pixel art is not the goal of this question, nothing related to direct pixel manipulation should be brought up here, but you're free to do exactly that :)
