• Chrome Mobile: The Mobile Web Developers Toolkit (Part 2)

  Chrome Mobile: The Mobile Web Developers Toolkit (Part 2) Building for mobile web requires a different mindset than desktop web development, and a different set of tools. The tools we're used to using often aren't available or would take up too much screen real estate. And going back to the dark ages of tweak/save/deploy/test/repeat isn't exactly optimal, so what can we do? Thankfully there are a number of great options - from remote debugging to emulation, mobile browsers are offering more and more tools to make our lives easier. We'll take a look at a couple of tools that you can use today to make cross platform mobile web development easier and then peer into the crystal ball to see what tools may bring in the future. Join us for Part 2 - as we take a look at a some of the many tools to make testing the mobile web easier. From: GoogleDevelopers Views: 0 0 ratings Time: 01:00:00 More in Science & Technology

• How to determine which cells in a grid intersect with a given triangle?

  - by Ray Dey

  I'm currently writing a 2D AI simulation, but I'm not completely certain how to check whether the position of an agent is within the field of view of another. Currently, my world partitioning is simple cell-space partitioning (a grid). I want to use a triangle to represent the field of view, but how can I calculate the cells that intersect with the triangle? Similar to this picture: The red areas are the cells I want to calculate, by checking whether the triangle intersects those cells. Thanks in advance. EDIT: Just to add to the confusion (or perhaps even make it easier). Each cell has a min and max vector where the min is the bottom left corner and the max is the top right corner.

• Cloud consolidation handling multi databases

  - by llaszews

  I have spoken about virtualization and the different types of virtualization. Which includes OS zones, application server domains, database schemas, VLANS and other approaches. Another approach is to create a virtually federated database in the cloud. DBSpaces is a company that has a technology to created a virtually federated database in the cloud. DBSpaces is a Virtual Database technology that allows an organisation thru a single Virtual Database access multiple data sources (or database spaces) in real-time. Additionally dbSpaces can be configured to access an organisations data internally using a remote gateway so that their dbSpace is seamless across the Public and Private cloud.

• How would I go about implementing a globe-like "ballish" map?

  - by rFactor

  I am new to 3D development and I have this idea of having the game world like our globe is - a ball. So, there would be no corners in the map and the game is top-down RTS game. I would like the camera to go on and on and never stop even though you are moving the camera to the same direction all the time. I am not sure if this is even possible, but I would really like to build a globe-like map without borders. Can this be done, and how exactly? I am using XNA, C#, and DirectX. Any tutorials or links or help is greatly appreciated!

• Writing Resumes for Internships?

  - by ProdigySim

  I'm an undergraduate student starting to look for internships. I understand a lot about how to embellish a real-world resume--emphasizing tasks done at previous jobs and whatnot--but I'm not sure if it will translate well to low-experience internship resumes. Internship Resumes are marked by: Few to no past Software-related full-time jobs or internships Few to no non-school-involved Software-related activities Obviously if you have no experience or activities to list, you're pretty well stuck. So let's assume we have one of each. I'm basically wondering: What is a company looking for most from Intern candidates? Past work, GPA/coursework, Outside projects (Open Source, etc), certain skill sets (languages) Should I be emphasizing tasks, or jobs/positions when listing my experiences? Are skills important to list? If so, which ones in particular?

• How to balance programming projects between feasibility and usefulness

  - by tyjkenn

  I've become fairly competent as a programmer, but I would not say I am a master. I work independently, most as a hobby, although I have done some freelance PHP work. I tend to find myself dabbling in a lot of things: Java Android SDK, Arduino, game scripting, Lua, etc. I've reached the point where I want to start a real software project, but cannot think of a small enough project that allows me enough practice, while still being able to publish a decent piece of software in a reasonable amount of time, and build up a portfolio. More specifically, I was looking at Ubuntu development, in Python, using the Quickly toolset, which includes the PyGTK libraries. So the question is, what is the best way to come up with a small project that is still useful, as a starting point to a software development career?

• How to get the 'Install alongside Windows' option, i only see 'Install inside Windows'?

  - by IanDess

  I created a bootable USB Stick with Ubuntu 13.10 and when i boot from it and try to install it i only get the option "Install inside Windows" and the button in the bottom right corner says "Restart to continue". But i don't want that, i want a real dual boot. I installed Ubuntu few days ago on my laptop and i clearly remember that it said "Install ALONGSIDE Windows". What should i do to get that option? PS i previously had Ubuntu installed on this PC from WUBI, but i uninstalled it.

• Is there an application or method to log of data transfers?

  - by Gaurav_Java

  My friend asked me for some files that I let him take from my system. I did not see he doing that. Then I was left with a doubt: what extra files or data did he take from my system? I was thinking is here any application or method which shows what data is copied to which USB (if name available then shows name or otherwise device id) and what data is being copied to Ubuntu machine . It is some like history of USB and System data. I think this feature exists in KDE This will really useful in may ways. It provides real time and monitoring utility to monitor USB mass storage devices activities on any machine.

• GPG Workflow in 11.04

  - by Ross Bearman

  At work we handle the transfer of small bits of sensitive data with GPG, usually posted on a secure internal website. Until Firefox 4 was released, we used FireGPG for inline decryption; however the IPC libraries that it relied upon were no longer present in FF4, making it unusable and it will no longer install in FF5. Currently I'm manually pasting the GPG blocks into a text file, then using the Nautilus context-menu plugin or the command line to decrypt the contents of the file. When we're handling large amount of these small files throughout the day this starts to become a real chore. I've looked around but can't seem to find much information on useful GPG clients in Ubuntu. A client that allowed me to paste in a GPG block and instantly decrypt it, and also paste in plaintext and easily encrypt it for multiple recipients would be ideal. So my question is does this exist? I can't seem to find anything about this with obvious searches on Google, so hopefully someone here can help, or offer an alternative workflow.

• Blender 2.6: How to Merge the Pros of Meshes and Surfaces

  - by fridojet

  there are two interesting kinds of objects: Meshes and Surfaces. Each of them offers very cool features. Object Type Specific Features Nice Features of Surfaces: (for example) They're as scalable as vector graphics (really nice!) You can build winding things real simply. Nice Features of Meshes: (for example) You can build organic things really good using the Sculpt Mode and a graphic tablet. You can use some special things like Physics. My Question There are things for which Surfaces are better and things for which Meshes are better. But how can I use both the best features of Surfaces and the best features of Meshes on one object at once? For example: How can I use Physics (like on Meshes) on lossless scalable objects (like Surfaces)? Thanks.

• Making video from 3D gaphics in OpenGL

  - by MVTC

  What are some of the preferred methods or libraries for creating video from an OpenGL graphics simulation? For example, I want to create a visualization(video) of an N-Body gravity simulation by rendering non-real-time OpenGL frames. The simulation is already coded, I just don't know how to convert it to video. EDIT: I am also interested in providing the described functionality: The user can adjust parameters including the time step between captured frames and then initiate the simulation. The user waits for the simulation to complete, and then can watch the results. The user is able to increase or decrease the playback speed of the simulation whereas in slow motion, more frames are used i.e., you see higher resolution time steps, and when the speed is increased, you see lower resolution time steps at a higher rate, but the frames per second flashing on the screen is constant.

• How Does Your Home Based Business Rank? Unlock the Mystery of Search Engine Optimization

  For many, the words "search engine optimization" (SEO) are simply confusing buzz words used by tech heads buried in the mysterious world of internet marketing. But listen up home based business owners, SEO can be a critical component of your marketing strategy, and when broken down to its basic level, SEO is merely a tool allowing you to use the various search engines such as Google or Yahoo! and others to gain visibility for your business and drive prospects to your website. SEO marketing is the process of improving the volume of traffic to a website through natural/organic (un-paid) search results. Unlike promoting your business via pay-per-click (PPC) strategies, which lists your business at the top of search engines such as Google or Yahoo! for a fee, SEO is a strategy with the goal of ensuring placement at the top without incurring expensive placement costs.

• Will GMails Greasemoney API help me: composing and sending messages, adding a button to the compose view, listing and sending drafts [migrated]

  - by Kent

  I want to create a Greasemonkey script for GMail and I've browsed through the GMail Greasemonkey 1.0 API documentation. I haven't fully understood what the API actually provides, which leads me to ask a few concrete questions. How will the API help if I want to: Add a button to the Compose view which executes some of my code. Compose and send a new message from scratch. List the current drafts. Pick a draft and send it. From what I can see it'll help me with 1 above, but I don't see any real interaction API parts which can help me with 2-4.

• Performance Driven Manufacturing

  Manufacturers are searching for new, creative ways to address growing demands of global manufacturing. They want the latest tools and technologies to boost performance from their operations, suppliers, partners, distributors, and extended ecosystem, and they need global views for better visibility - both internally and across the extended supply chain. In addition, operations must move information more effectively to gain real-time insight into manufacturing shop floor status. Whether it's inside the plant or outside the traditional factory walls, manufacturers are searching for solutions to help them produce more for less, lower their total cost of ownership (TCO), and improve their return on investment (ROI).

• How to get local point inside a body where mouse click occurred in box2d?

  - by humbleBee

  I need to find out the point inside a body, lets say a rectangular object, where the mouse was clicked on. I'm makin a game where the force will be applied depending on where the mouse was clicked on the body. Any ideas? Will body.GetLocalPoint(b2vec2) work? I tried by passing the mouse coordinates when the click occurred when inside the body but if the body's position is (400,300) in world coordinates then for trace(body.GetLocalPoint(new b2vec2(mouseX,mouseY)).x); I get some value between 380 to 406 or something (eg. 401.6666666). I thought getLocalPoint will give something like x=-10 when clicked to the left of the centre of body or x=15 when clicked to the right. Language is As3 btw.

• Are there good replacements for client-side java in web programming? [closed]

  - by varesa

  Now since the latest java exploit, and many others in the past, people are again recommended to get rid of java on their computers for good. I, as a java web applications developer, am think about possible alternatives. Many seem to have gotten rid of java, so I would not like to develop for an environmet, that users do not have on their computers, and that they are not willing to install for security reasons. Are there any other real options that HTML5 + JS? (Don't take me wrong about not wanting HTML5+JS, I just want to know the options)

• Is it possible to setup a DHCP server only for local virtual machines?

  - by thiesdiggity

  I have a quick question. I have a bunch of virtual machines (VMWare Workstation) running on an Ubuntu server and have found that VMWare NAT (DHCP) service is unreliable and slow. I have to use NAT instead of bridging because the server is in a data-center that does not have DHCP and I don't have enough static IP's for all the VMs. Is it possible to setup the host (Ubuntu) to be a DHCP server but only for the local virtual machines? The server has 2 network interfaces, so I'd set eth0 to be a static IP, which connects to the outside world, and eth1 to listen for DHCP. Now, I am thinking if I don't want DHCP to broadcast I would just not connect a cable to eth1 and setup the VM's to use bridging on eth1. That way DHCP would not broadcast through my network but be listening on that interface. Would that setup work?

• Microsoft Releasing Windows 8 in Late October

  The one thing Microsoft did not give was the exact date in October that this latest operating system would become available. But that may be difficult to predict. Brandon LeBlanc, Microsoft communications manager, stated only that Windows 8 is on track for a release to manufacturers (RTM) in August. The company, on average, produces a new version of Windows every three years; the last one to come out was Windows 7, back in October of 2009. The operating system will enjoy a widespread release, coming out in 109 languages across 231 markets throughout the world. It will be used not only in PCs...

• Proxy Client for Ubuntu

  - by WindowsEscapist

  I want to use a proxy for web browsing similar to Ultrasurf for Windows. I've tried to use TOR, but it isn't working! The problem is whenever I search something along the lines of "ubuntu + linux proxy", sites assume that I want to set up a proxy server rather than use one. I just want something with little to no configuration needed (i.e. I don't have my own proxy server). UltraSurf is a free software which enables users inside countries with heavy Internet censorship to visit any public web sites in the world safely and freely. Users in countries without internet censorship also use it to protect their internet privacy and security.
