• Associating Palettes with View TopComponents

  - by Geertjan

  A side effect of changes in NetBeans Platform 7.1 in the NetBeans window system is that palettes can now be created for view TopComponents. Below, a TopComponent in the "explorer" position is selected, which results in the Palette opening and showing items that can be dragged into the TopComponent: And here, in the same application, a TopComponent in the "output" position is now selected, which causes the Palette to open, showing items that are relevant to the TopComponent: I copied code used in the above two TopComponents from this blog entry: https://blogs.oracle.com/geertjan/entry/simple_component_palette Related issue: http://netbeans.org/bugzilla/show_bug.cgi?id=209238

• How can I make sure my website will be available during a presentation?

  - by johnny_s

  I have an online presentation to do next week and I have it all ready to go. The website is HTML and CSS only (no DB), and currently resides on my shared hosting account. Now, although my shared hosting is (relatively) reliable, I have noticed that recently they have been making some changes and my website has been unavailable at times. I don't want this to happen to me on the morning of my presentation, so I am asking what is the best way to prepare for such a thing? My domain is www.presentation.mydomain.com and I would like to keep this if possible (even if issues arise). I have been thinking of a few alternatives: Host my site on two different domains or servers (but what about the domain name?) Have a portable XAMPP version on a USB stick (again, domain name?) Possible failover site/location Update: The presentation will be carried out on their laptop, not mine. So I am unable to install any software.

• Debugging-Setting Consoles in Games

  - by ShrimpCrackers

  Right now I have the graphical and input portions of a console for my game (command parsing hasn't been implemented yet). I was wondering how you would go about making changes to properties in game objects. For example, if I typed in the console: skeletonMonster maxHP 20 That would change all of the existing in-game skeletons' max hit points to 20. After you parse this information what are some ways to change the value? How can I change the variable(s) without violating information hiding? I'd like to implement this so I don't have to change variables in the code and recompile every time while playtesting.

• Review before or after code commit, which is better?

  - by fifth

  Traditionally we performed code review before commit, I had an argument with my colleague today, who preferred code review after commit. First, here's some background, we got some experienced developers and we also got new hires with almost zero programming practice. we'd like to perform fast and short iterations to release our product. we all team members locate at same site. The advantages of code review before commit I've learned, mentor new hires try to prevent errors, failures, bad designs in early developing cycle learn from others knowledge backup if someone quits But I also got some bad experience, like low efficiency, some changes may be reviewed over days hard to balance speed and quality, especially for newbies some guy felt distrust As to post-review, I just knew little about this, but the most thing I worried about is the risk of losing control, people never review. Any opinions?

• iptables allow dyndns domain name and auto update rules

  - by user3215

  I have registered with dyndns domain for my dynamically changing public ip address to use with iptable rules. On a server I've allowed some ports for this domain in the iptables configuration like the below entries: -A INPUT -s mycompany.dyndns.com -p tcp -m tcp --dport 22 -j ACCEPT -A INPUT -s mycompany.dyndns.com -p tcp -m tcp --dport 3306 -j ACCEPT -A INPUT -s mycompany.dyndns.com -p tcp -m tcp --dport 21 -j ACCEPT But when ever my modem restarts, I couldn't connect to these allowed ports as public ip changes with modem restart and are not updated in the iptables on the server. Is there any option to automatically update iptable rules on server.

• Django - how should I implement generic apps that have dependencies on other generic apps?

  - by MikeRand

  Hi all, I'm using Marty Alchin's Django app that creates historical records (add, change, delete) based on models found in other Django apps (found in chapter 11 of Pro Django). Question: how do I implement this historical_records app into my other generic Django apps while still maintaining loose coupling? For example, I have a generic app (forecast) that manages a Forecast (of any other model). For one project, I'd like to use historical_records so that I can track changes to a Forecast instance. But I don't want to require all future projects that might want to use forecast to also use historical_records. Any guidance would be greatly appreciated. Thanks, Mike

• BizTalk: namespaces

  - by Leonid Ganeline

  BizTalk team did a good job hiding the .NET guts from developers. Developers are working with editors and hardly with .NET code. The Orchestration editor, the Mapper, the Schema editor, the Pipeline editor, all these editors hide what is going on with artifacts created and deployed. Working with the BizTalk artifacts year after year brings us some knowledge which could help to understand more about the .NET guts. I would like to highlight the .NET namespaces. What they are, how they influence our everyday tasks in the BizTalk application development. What is it? Most of the BizTalk artifacts are compiled into the NET classes. Not all of them… but I will show you later. Classes are placed inside the namespaces. I will not describe here why we need namespaces and what is it. I assume you all know about it more then me. Here I would like to emphasize that almost each BizTalk artifact is implemented as a .NET class within a .NET namespace. Where to see the namespaces in development? The namespaces are inconsistently spread across the artifact parameters. Let’s start with namespace placement in development. Then we go with namespaces in deployment and operations. I am using pictures from the BizTalk Server 2013 Beta and the Visual Studio 2012 but there was no changes regarding the namespaces starting from the BizTalk 2006. Default namespace When a new BizTalk project is created, the default namespace is set up the same as a name of a project. This namespace would be used for all new BizTalk artifacts added to this project. Orchestrations When we select a green or a red markers (the Begin and End orchestration shapes) we will see the orchestration Properties window. We also can click anywhere on the space between Port Surfaces to see this window.   Schemas The only way to see the NET namespace for map is selecting the schema file name into the Solution Explorer. Notes: We can also see the Type Name parameter. It is a name of the correspondent .NET class. We can also see the Fully Qualified Name parameter. We cannot see the schema namespace when selecting any node on the schema editor surface. Only selecting a schema file name gives us a namespace parameter. If we select a <Schema> node we can get the Target Namespace parameter of the schema. This is NOT the .NET namespace! It is an XML namespace. See this XML namespace inside the XML schema, it is shown as a special targetNamespace attribute Here this XML namespace appears inside the XML document itself. It is shown as a special xmlns attribute.   Maps It is similar to the schemas. The only way to see the NET namespace for map is selecting a map file name into the Solution Explorer. Pipelines It is similar to the schemas. The only way to see the NET namespace for pipeline is selecting a pipeline file name into the Solution Explorer. z Ports, Policies and Tracking Profiles The Send and Receive Ports, the Policies and the BAM Tracking Profiles do not create the .NET classes and they do not have the associated .NET namespaces. How to copy artifacts? Since the new versions of the BizTalk Server are going to production I am spending more and more time redesigning and refactoring the BizTalk applications. It is good to know how the refactoring process copes with the .NET namespaces. Let see what is going on with the namespaces when we copy the artifacts from one project to another. Here is an example: I am going to group the artifacts under the project folders. So, I have created a Group folder, have run the Add / Existing Item.. command and have chosen all artifacts in the project root. The artifact copies were created in the Group folder: What was happened with the namespaces of the artifacts? As you can see, the folder name, the “Group”, was added to the namespace. It is great! When I added a folder, I have added one more level in the name hierarchy and the namespace change just reflexes this hierarchy change.  The same namespace adjustment happens when we copy the BizTalk artifacts between the projects. But there is an issue with the namespace of an orchestration. It was not changed. The namespaces of the schemas, maps, pipelines are changed but not the orchestration namespace. I have to change the orchestration namespace manually. Now another example: I am creating a new Project folder and moving the artifacts there from the project root by drag and drop. We will mention the artifact namespaces are not changed. Another example: I am copying the artifacts from the project root by (drag and drop) + Ctrl. We will mention the artifact namespaces are changed. It works exactly as it was with the Add / Existing Item.. command. Conclusion: The namespace parameter is put inconsistently in different places for different artifacts Moving artifacts changes the namespaces of the schemas, maps, pipelines but not the orchestrations.

• Good resources for learning about graphics hardware

  - by Ken

  I'm looking for some good learning resources for graphics hardware (and associated low level software). Basically I want to learn more about what goes on underneath the opengl/direcx API layers in terms of how things are implemented. I familiar with what happens in principle during the various stages of the rendering pipeline (viewing, projection, clipping, rasterization etc). My goal is to be able to make better and more informed decisions about tradeoffs and potential optimisations when graphics/shader programming with respect to the following kinds of issues; batching view culling occlusions draw order avoiding state changes triangles vs pointsprites texture sampling etc Basically whatever the graphics programmer needs to know about modern graphics hardware in order to become more effective. I'm not really looking for specific optimisation techniques, rather I need more general knowledge so that I will naturally write more efficient code.

• design practice for business layer when supporting API versioning

  - by user1186065

  Is there any design pattern or practice recommended for business layer when dealing with multiple API version. For example, I have something like this. http://site.com/blogs/v1/?count=10 which calls business object method GetAllBlogs(int count) to get information http://site.com/blogs/v2/?blog_count=20 which calls business object method GetAllBlogs_v2(int blogCounts) Since parameter name is changed, I created another business method for version 2. This is just one example but it could have other breaking changes for which it requires me to create another method to support both version. Is there any design pattern or best practice for business/data access layer I should follow when supporting API Versioning?

• Public versus private inheritance when some of the parent's methods need to be exposed?

  - by Vorac

  Public inheritance means that all fields from the base class retain their declared visibility, while private means that they are forced to 'private' within the derived class's scope. What should be done if some of the parent's members (say, methods) need to be publicly exposed? I can think of two solution. Public inheritance somewhat breaks encapsulation. Furthermore, when you need to find out where is the method foo() defined, one needs to look at a chain of base classes. Private inheritance solves these problems, but introduces burden to write wrappers (more text). Which might be a good thing in the line of verbosity, but makes changes of interfaces incredibly cumbersome. What considerations am I missing? What constraints on the type of project are important? How to choose between the two (I am not even mentioning 'protected')? Note that I am targeting non-virtual methods. There isn't such a discussion for virtual methods (or is there).

• What is supposed to happen when you install Gmail webapp?

  - by ubuntico

  I have installed Gmail (and other Google as well) webapps into Ubuntu 14.04 64-bit. After that I rebooted the system hoping that webapps will integrate into the system. But after logging back to the system, I see no changes. If I click on email envelope (top bar), I don't see my inbox. Also if I try to search email in Dash via gmail keyword, nothing happens as well. Am I using this wrongly or webapps don't work? What was supposed to happen when I install webapps? Note: I did start the Gmail app from Dash and logged in

• Will removing unused query string parameters negatively affect SEO?

  - by trm

  Will changing links to remove query string parameters that are no longer used have any negative impact on search engine rankings? Say I have a page about.php on my site, and all of my links to this page are of the form http://www.example.com/about.php?foo=bar and I've made some changes to the script such that the parameter foo is no longer used. I would like to remove the unused parameter from the links so the URL will look cleaner, but I am concerned that this could cause problems with SEO. Is it safe to remove ?foo=bar from my links?

• Ubuntu multiple issues (blank screen)

  - by Donavon

  Computer Specs I am having difficulties, to get Ubuntu 11.10 to work. For the 11.10 version, if I click install, or if I click try Ubuntu, I only get a blank screen, that just stays there. If I use "nomodeset", it changes to a loading screen and after about 2 minutes it goes back to black screen - however, before it goes black, i get a few errors, like: bad target number, or passwd error mode (something like that). I've also tried (xforcevesa, i915.modeset=0, nomodeset, radeon.modeset=0, i915.modeset=1) I have also tried the alternate installation, which installed fine, however when I boot up, select it from "grub", it goes black. I did manage to install 10.04, however the screen resolution was 800x600 and I couldn't fix it to 16:9 (my resolution). I don't wanna use 10.04, because I would like the new one 11.10, and would like to use it. Any help would be GREATLY appreciated. Thank you

• How to edit files in a terminal with vim?

  - by andrew.46

  It is not always possible to edit and create files in a terminal and I would like to get the answers to the basics of manipulating files in a terminal using vim under Ubuntu Linux. Specific questions I have are: How can I open text files for editing? How can I save the file? How can I save the file with a different name? How can I leave the file without saving the changes? What settings are best in my configuration file and where is this file? How do I set the colors for vim? How do I show line numbers in vim and can this be toggled? A lot of questions here but I believe these questions and their answers should cover basic vim usage...

• Why are Back In Time snapshots so large?

  - by Chethan S.

  I just backed up the contents of my home partition onto my external hard drive using Back In Time. I browsed to the backed up contents in the external drive and under properties it showed me the size as 9.6 GB. As I read that in next snapshots I create, Back In Time does not backup everything but creates hard links for older contents and saves newer contents, I wanted to test it. So I copied two small files into my home partition and ran 'Take Snapshot' again. The operation completed within a minute - first it checked previous snapshot, assessed the changes, detected two new files and synced them. After this when I browsed to the backed up contents, I was surprised to see the newer and older backup taking up 9.6 GB each. Isn't this a waste of hard drive space? Or did I interpret something wrongly?

• JavaFX 2.1.1 Documentation

  - by NancyH

  JavaFX 2.1.1 released on June 12, and few documents were updated on the docs.oracle.com/javafx website. Besides a new set of release documentation, the Concurrency in JavaFX article was updated with a discussion of how to cancel a task, with a code sample to illustrate that. A new section describes the WorkerStateEvent class and how to use the convenience methods such as cancelled, failed, running, scheduled, and succeeded, which are invoked when the Worker implementation state changes. Other documents were updated to reflect minor bug fixes, many of them contributed by JavaFX readers using the feedback alias in the sidebar of all of our documentation. Yes, we do respond and pay attention to what you say and at least try to point you in the right direction if we can't solve a problem you're having with a tutorial. We appreciate your feedback!

• Is it possible for a good programmer to have never used version control?

  - by lortabac

  I am looking for an expert programmer to help solve a difficult situation. The interviews so far have been surprisingly disappointing. The best candidate so far is a very experienced programmer who has never used version control software. The problem in itself might not be too serious because it is something which can be learned in a short time. But there is a deeper aspect, which worries me: How is it possible to actively develop software for 10-15 years without ever needing version control? Is the fact itself of not looking for a solution to the problem of tracking changes a sign of a wrong attitude to programming?

• How do I install Ubuntu to a USB key?

  - by badp

  If you are hurrying to reply, System ? Administration ? StartUp Disk Creator -- no, that's not what I'm talking about. I want to try Ubuntu 11.04's Unity without touching my existing Ubuntu install. To do this, I need to install the nVidia drivers first (sigh). To do this, I need changes to persist a reboot. To do this, I need to really install Ubuntu on a USB key. How do you do that? What I tried I tried to make a USB key from Testdrive, then boot from it, then choose "Install Ubuntu." The installer refused to install to the installation media itself. I tried, from my installed copy of Ubuntu: sudo kvm /dev/sdb --cdrom .cache/testdrive/iso/ubuntu_natty-desktop-i386.iso ...but the installer didn't detect the disk properly.

• How serious/common are wordpress updating issues

  - by gyaani_guy

  I am currently deciding between a CMS (joomla OR wordpress )to dive deep into. I think I would go for wordpress, but the only thing thats holding me back are any potential issues with updating wordpress- that updating wordpress can break plugins, but is necessary because of security issues. How drastic are the changes in wordpress? say over a period of 2-3 years? from the perspective of someone intending to dive head first in its code. Should I fear regular updates breaking stuff ? Thanks

• Hosting a website from a dynamic IP

  - by nick

  I recently upgraded my internet to the point that it is much faster and more reliable than my current webhost. I would like to move my current domain to be hosted at home, but my IP address is dynamic. As far as I know, I only get a new IP when I restart my modem and or router (which is almost never) or when cable one (my ISP) pushes out a firmware update (rarely). There are a few ways I can see doing this 1) convince my ISP to give me a static IP 2) assign my router my current IP to force a static IP (which might work?) 3) set my dns record to my current IP address and update it on the rare occasions that it changes. Obviously I'm hoping that the first one works, but I don't want to pay a lot of extra money (if that's what it takes) to get a static IP address. Has anyone had any luck with something like that?
