• The Web Weekly Newsletter

  - by dwahlin

  Several months ago I created a few FlipBoard magazines that a ton of developers (over 50,000!) have used to access content on JavaScript, HTML5, AngularJS, Azure, XAML, Web API, and more. While the feedback on the magazines has been super positive, several people have asked about having the content pushed to them. I’m generally too busy to remember to go check a particular link on a regular basis so I definitely understood and agree with the comments. I’m happy to announce a new newsletter I’m calling the Web Weekly. It’ll highlight content across the different FlipBoard magazines plus other sources and go out to subscribers a few times a month (weekly when possible). The first issue is ready to go and includes a “video highlights” segment I created to show some of my favorite content in the first issue. If you’re interested in staying on top of all the cutting edge Web technologies feel free to subscribe below!   Here’s a sample of some of the articles included:     Here’s the video from the first edition of the newsletter:   Subscribe to the newsletter below….

• How to shutdown Windows 8 PC without using mouse?

  - by Gopinath

  Windows 8 sports a re-imagined desktop and tablet user interface with touch friendly Metro looks. One of the major changes in Windows 8 for a common users  is the lack of start menu, with which we got friended for more than a decade. On Windows 8 we would be missing it. As there is no start menu in Windows 8, the way you shutdown a Windows 8 computer is a bit different. To shutdown using Mouse, you need to hover on the top right edge of the screen to open the hidden menu,  go to "Settings"  tab -> "Power" -> Then choose for "Shut down", "Sleep" or "Restart".  That’s a lot of Mouse movement work and if you are a power user then you may not like to do that. How about shutting down the PC using Keyboard? Here are the two ways to shutdown the PC using keyboard Keyboard shortcuts With the help of keyboard shortcuts you can navigate to Power options of Windows 8. Press Win + C to bring the Settings Charm and use Arrows and Enter keys to navigate to access Shutdown menu. This is one of the easiest way to shutdown the PC without using Mouse. Run Command If you don’t like to go through the Setting menu, you can use the traditional Run commands. Press Win + R to open Run dialog and enter the command shutdown -s -t 0 to immediately shutdown the PC.

• How do Unity 12.04/Compiz bindings really work?

  - by Daniel

  There is a bewildering array of places to set bindings, all inconsistent with one another. E.g. in Unity's System Settings having the Ctrl-key highlight the mouse position is an on/off choice. I like the feature, but not on such a prominent key where I keep activating it accidentally. The keyboard shortcuts allow only one binding per command, where I might like a convenient one on the external keyboard and an emergency alternative for when I'm on the road. Keyboard custom shortcuts has a nice interface, but allows only key bindings — besides it doesn't seem to work for me. So I activated CCSM Commands. There I have the choice of key-, mouse- and/or edge bindings. Whereas some places in CCSM offers only one or two of these binding possibilities, randomly at the whim of the programmer. I have not found a way to differentiate a mouse-drag from a click. E.g. I want <SuperMouse1-drag anywhere on a window to move it, while if I don't drag, it should be raise-lower. On the title bar I want the same without needing the <Super key. Now I find raise-lower only in System Settings where I can't assign a mouse binding. If therefore in CCSM I fallback to only lower and put move on the same binding, the window already gets lowered on mouse down, and I can then invisibly move it. Very useful! I have <Altasciicircum get in the way of an Emacs binding, with some to me useless popup overlay. I can find it nowhere, so I can't turn it off. So how can I go without these frontends until they have matured, and instruct Compiz directly, for example in the way Emacs or Sawfish have keymaps, and separate ones for each context, with inheritance?

• How can I get SLI working with 295.40?

  - by Steve

  I've been doing a lot of googling these last few hours and I'm not having much luck. Perhaps I don't know exactly what I am looking for. I just recently installed Ubuntu 12.04LTS x86_64. Looks beautiful! I have two GTX470's in SLI, and I am finally migrating my desktop over given the hopeful gaming support as of late. My laptop has been enjoying multiple distros of Ubuntu for a couple years now. However, new problems come with unexplored territory, here. At first, I only had one working monitor of my two. Over on nvidia-xconfig I fixed that, but the only solution that actually worked was twinview. Just recently I read here that twinview is not compatible with SLI. Sweet. When I try to tell it, oh hey, use a separate XScreen, configure it the way I want it, click save to configuration file, enter my password, then a sudo restart lightdm, it's broken. One screen blacks or whites out (Couldn't tell you the specific conditions for each, I'm dubious at this point,) and I get this huge error dialogue box upon login. Something about incompatible resolutions if I remember right. Though I am sure I set the resolutions for each screen correctly. Anyway, when I try to enable SLI (sudo nvidia-xconfig --sli=On) despite the fact it hates twinview, unity breaks. The sidebar is there, but only one screen works, the mouse is trapped running along the left edge of it, and the background of the sidebar is a solid blue. Anyway, this ended up being entirely too verbose, I'm sorry, but could anyone part some wisdom please? It would be appreciated!

• EE vs Computer Science: Effect on Developers' Approaches, Styles?

  - by DarenW

  Are there any systematic differences between software developers (sw engineers, architect, whatever job title) with an electronics or other engineering background, compared to those who entered the profession through computer science? By electronics background, I mean an EE degree, or a self-taught electronics tinkerer, other types of engineers and experimental physicists. I'm wondering if coming into the software-making professions from a strong knowledge of flip flops, tristate buffers, clock edge rise times and so forth, usually leads to a distinct approach to problems, mindsets, or superior skills at certain specialties and lack of skills at others, when compared to the computer science types who are full of concepts like abstract data types, object orientation, database normalization, who speak of "closures" in programming languages - things that make little sense to the soldering iron crowd until they learn enough programming. The real world, I'm sure, offers a wild range of individual exceptions, but for the most part, can you say there are overall differences? Would these have hiring implications e.g. (to make up something) "never hire an electron wrangler to do database design"? Could knowing about any differences help job seekers find something appropriate more effectively? Or provide enlightenment or some practical advice for those who find themselves misfits in a particular job role? (Btw, I've never taken any computer science classes; my impression of exactly what they cover is fuzzy. I'm an electronics/physics/art type, myself.)

• Square game map rendered as sphere with OpenGL

  - by Roflha

  Okay so I have been trying to find a good way to do this for a while now and so far I have nothing. For a hobby project of mine I have created a finite voxel world (similar to minecraft), but as I said, mine is finite. When you reach the edge of it, you are sent to the other side. That is all working fine along with rendering the far side of the map, but I want to be able to render this grid as a sphere. Looking down from above, the world is a square. I basically want to be able to represent a portion of that square as a sphere, as if you were looking at a planet. Right now I am experimenting with taking a circular section of the map, and rendering that, but it look to flat (no curvature around the edges). My question then, is what would be the best way to add some curvature to the edges of a 2d circle to make it look like a hemisphere. However, I am not overly attached to this implementation so if somebody has some other idea for representing the square as a planet, I am all ears.

• Dim (NEARLY blank) laptop screen, secondary screen works - why?

  - by LIttle Ancient Forest Kami

  My laptop screen is (almost) black while my secondary screen is fine. I believe it to be backlight / brightness related. Problem description it starts when I start the laptop system loads and works fine, just screen has problems I can see the screen though very faintly / dimly - it's hard to see anything which ain't very white e.g. starting screen has big Thinkpad logo in white, large font - I can see it, though very dimly second screen works very well Official backligtht debugging: using acpi setting as prescribed there for Thinkpads didn't help I can see an entry in /sys/class/backlight/ and it changes when I press hotkeys for brightness (current backlight power for instance goes up or down) acpi-off didn't helpm neither did acpi_backlight=vendor Hardware data Laptop is Thinkpad Edge with glossy screen. 4 processors, 2 cores, exemplary CPU data from cat /proc/cpuinfo reports Genuine Intel i5 (M 480 @ 2.67GHz).

• Microsoft Lowers Cloud Barrier To Entry

  - by Herve Roggero

  Once in a while, the technology stack changes enough to create a disturbance in the IT industry. Microsoft did just that today and has officially closed the gap with its #1 competitor: Amazon. What is remarkable is that Microsoft is no longer an alternative to Amazon, it is becoming a clear leader in that space. Some of the new features include official support for durable Virtual Machines with high availability (cross-geographic replication), free WebSites to try Azure, MySQL database at no charge, a new distributed low-latency cache feature, Linux support, support with existing VPN hardware for seamless on-premise integration, a new partner ecosystem and much, much more. Amazon had an edge against Windows Azure in the IaaS (Infrastructure as a Service) space, until now. With the latest release from Microsoft Azure, the gap has been filled. In fact, it seems Amazon may now have a gap to fill… This is great news to everyone; it seems that cloud offerings are becoming more standardized with the more mature cloud providers, and the management stack and quality of service of each cloud provider is increasingly becoming the differentiator. With today’s announcements, it is becoming clear that cloud providers are pushing hard to increase their service footprint and lowering typical barriers to entry such as support for open-source operating systems, free trial offers, higher availability, faster deployment times and simpler enterprise integration.

• Google Analytics Social Tracking implementation. Is Google's example correct?

  - by s_a

  The current Google Analytics help page on Social tracking (developers.google.com/analytics/devguides/collection/gajs/gaTrackingSocial?hl=es-419) links to this page with an example of the implementation: http://analytics-api-samples.googlecode.com/svn/trunk/src/tracking/javascript/v5/social/facebook_js_async.html I've followed the example carefully yet social interactions are not registered. This is the webpage with the non-working setup: http://bit.ly/1dA00dY (obscured domain as per Google's Webmaster Central recommendations for their product forums) This is the structure of the page: In the : ga async code copied from the analytics' page a script tag linking to stored in the same domain. the twitter js loading tag In the the fb-root div the facebook async loading js including the _ga.trackFacebook(); call the social buttons afterwards, like so: (with the proper URL) Tweet (with the proper handle) That's it. As far as I can tell, I have implemented it exactly like in the example, but likes and twitts aren't registered. I have also altered the ga_social_tracking.js to register the social interactions as events, adding the code below. It doesn't work either. What could be wrong? Thanks! Code added to ga_social_tracking.js var url = document.URL; var category = 'Social Media'; /* Facebook */ FB.Event.subscribe('edge.create', function(href, widget) { _gaq.push(['_trackEvent', category, 'Facebook', url]); }); /* Twitter */ twttr.events.bind('tweet', function(event) { _gaq.push(['_trackEvent', category, 'Twitter', url]); });

• How can I determine the first visible tile in an isometric perspective?

  - by alekop

  I am trying to render the visible portion of a diamond-shaped isometric map. The "world" coordinate system is a 2D Cartesian system, with the coordinates increasing diagonally (in terms of the view coordinate system) along the axes. The "view" coordinates are simply mouse offsets relative to the upper left corner of the view. My rendering algorithm works by drawing diagonal spans, starting from the upper right corner of the view and moving diagonally to the right and down, advancing to the next row when it reaches the right view edge. When the rendering loop reaches the lower left corner, it stops. There are functions to convert a point from view coordinates to world coordinates and then to map coordinates. Everything works when rendering from tile 0,0, but as the view scrolls around the rendering needs to start from a different tile. I can't figure out how to determine which tile is closest to the upper right corner. At the moment I am simply converting the coordinates of the upper right corner to map coordinates. This works as long as the view origin (upper right corner) is inside the world, but when approaching the edges of the map the starting tile coordinate obviously become invalid. I guess this boils down to asking "how can I find the intersection between the world X axis and the view X axis?"

• Space Invaders-type game: Keeping the enemies aligned with each other as they turn around?

  - by CorundumGames

  OK, so here's the lowdown of the problem I'm trying to solve. I'm developing a game in PyGame that's a cross between Space Invaders and Columns. I'm trying to make the motion of the enemies similar to that of the aliens in Space Invaders; that is, they're all clustered in a grid, and if even one hits the side of the screen, the entire formation moves down and turns around. However, the motion of these aliens is continuous (as continuous as a monitor can be, anyway), not on a discrete grid like in the original. The enemies are instances of an Enemy class, and in turn they're held by a 2D array in a enemysquadron module (which, if you don't use Python, is in this case essentially a singleton due to the way Python modules work). Inside the Enemy class I have a class-scope velocity vector that is reversed every time an Enemy object touches the edge of the screen. This won't do, though, because as time goes on the enemies just become disorganized and jumbled (i.e. not in a grid as planned). I haven't implemented the Enemies going downward yet, so let's not worry about that right now. Any tips?

• Quitting a small start-up where you are a primary developer?

  - by programmx10

  Just curious to hear from other people who may have been in similar situations. I work for a small startup (very small) where I am the main developer for a major part of the app they are building, the other dev they have does a different area of work than I do so couldn't take over my part. I've been with the company 5 months, or so, but I am looking at going to a more stable company soon because its just getting to be too much stress, overtime, pressure, etc for too little benefit and I miss working with other developers who can help out on a project. The guy is happy with my work and I think I've helped them get pretty far but I've realized I just don't like being this much "on the edge" as its hard to tell what the direction of the company is going to be since its so new. Also, even though I'm the main dev for the project, I would still only consider myself a mid-level dev and am selling myself as such for the new job search. Just to add more detail, I'm not a partner or anything in the company and this was never discussed, so I just work on a W2 (with no benefits of course). I work at home so that makes it easier to leave, I guess, but I don't want to just screw the guy over but also don't want to be tied in for too long. Obviously I would plan to give 2 weeks notice at least, but should I give more? How should I bring up the subject because I know its going to be a touchy thing to bring up. Any advice is appreciated UPDATE: Thanks everyone for posting on this, I have now just completed the process of accepting an offer with a larger company and quitting the startup. I have given 2 weeks notice and have offered to make myself available after that if needed, basically its a really small company at this point so it would only be 1 dev that I would have to deal with... anyways, it looks like it may work out well as far as me maintaining a good relationship with the founder for future work together, I made it out to be more of a personal / lifestyle issue than about their flaws / shortcomings which definitely seems to help in leaving on a good note

• Ubuntu for Phones / Touch vs Android, IOS and BlackBerry OS

  - by Ome Noes

  Currently I have a LG Google Nexus 4 with lots of issues because of the latest android 4.3 update. Since the update my battery drains within 7 hours when in it's standby / idle and even faster when I use it normaly! Before the Nexus 4 I had an Iphone but got sick of IOS because for me it's to much of a closed operating system and I dislike having to work with either Windows or Itunes. At this point neither Google or LG is willing to provide me (and all the others that have similar Nexus 4 problems) with a solution or even a reaction... Also i'm not very fond of the idea that the NSA (and maybe others) can and is currently monitoring millions of Android, IOS and BlackBerry OS devices all over the world. Since i've been using Ubuntu now very happily for almost 5 years I see Ubuntu for Phones / Touch as the only remedy for all this BS. Please be so kind to let me know when you will have a fully functioning version of your Ubuntu for Phones / Touch ready for consumer use. I'm realy sad that the Ubuntu Edge campaign didn't work out and hope to see lots and lots of future smartphones outfitted with Ubuntu a.s.a.p.! Keep up the good work!

• Learning curve for web development

  - by refro

  At the moment our team has a huge challenge, we're being asked to deliver a new GUI for an embedded controller. The deadline is very tight and is set on April 2013. Our team is very diverse, some people are on the level of functional programming (mostly C), others (including myself) have mastered object oriented programming (C++, C#). We built a prototype for Android, although it has its quirks, it is mostly just OO. For the future there is a wish to support multiple platforms (Windows, Android, iOS). In my opinion a HTML5 app with a native app shell is the way to go. When gathering more information on the frameworks to use etc., it became obvious to me a paradigm shift is needed. None of us have a web background so we need to learn from the ground up. The shift from functional to OO took us about 6 months to become productive (and some of the early subsystems were rewritten because they were a total mess). Can we expect the learning curve to be similar? Can this be pulled off with a web app? (My feeling says it will already be hard to pull off as a native app which is at the edge of our comfort zone).

• Connecting two monitors at the corners

  - by fastmultiplication

  I am using two separate X screens on two monitors and I would like them to be connected at the lower right corner. That is, if you move to the lower right corner of screen0 the mouse should appear at the upper left of screen1. I do not want an entire edge of each monitor to be permeable to the mouse. I modified the xorg.conf file like so: Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" 0 0 Screen 1 "Screen1" Relative "Screen0" 1200 1000 InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" EndSection (screen 0's resolution is 1280x1024) so there is a bit of overlap. However whenever I move the mouse to the bottom of screen0, the pointer appears at the upper left of screen1. And, the entire top of screen1 is permeable to the mouse and brings it to the lower left corner of screen0. I have tried various numbers in following the "relative" statement - if I put 1280 1024 the mouse does not cross over at all. If I use 1280 1023 the entire right side of screen0 is permeable. I haven't been able to find any documentation about how to explicitly tell the mouse where to crossover - is there some? It seems that xorg is being really aggressive in guessing where the mouse crossover should take place. Does anyone know how to do this? Thanks!

• Project Showcase: SaaS Web Apps Hits a Home Run with New SCMS Database

  - by Webgui

  We love seeing projects from start to finish, and we’re happy to share the latest example with you. Who: SaaS Web Apps – they use Software as a Service to create web applications that look and feel like desktop applications. What: SaaS Web Apps needed to build a Sports Contract Management System (SCMS) for one of its customers, Premier Stinson Sports. Why: The SCMS database is used for collecting, analyzing and recording college coach and athletic directors’ employment and contract data. The Challenge: Premier Stinson Sports works with a number of partners, each with its own needs and unique requirements. For example, USA Today uses the system to provide cutting edge news analysis while The National Sports Law Institute of Marquette University Law School uses it to for the latest sports contract data and student analysis. In addition, the system needed to be secure due to the sensitivity of the data; it was essential that the user security and permissions be easily configurable. As always, performance was a key factor, especially with the intense reporting and analytical capabilities for this project. Because of this, most of the processing had to be done on a dedicated server but the project called for the richness and responsiveness of a desktop application. The Solution: To execute the project, SaaS Web Apps used APS.Net-based Visual WebGui from Gizmox, combined with SQL Server 2008 and SQL Reporting Services. This combination resulted in a quick deployment for SaaS Web Apps’ customers. The Result: The completed project gave each partner the scalability and availability of a web application with the performance and security of a desktop application. As an example, USA Today pulls data from this database to give readers the latest sports stats – Salary analysis of 2010 Football Bowl Subdivision Coaches.

• Need guidelines for studying Game Development

  - by ShutterBug

  Hello Everyone, I've completed my graduation in Computer Science and currently working as a Software Engineer in a software company. I was wondering if I can build my career in Game Development. If so, what should be my approach. I've a few questions: Which universities to apply for masters? Preferably in Canada. Scholarships available? How shall I prepare myself before applying which shall give me an edge or advantage over others? I know Java, C#, PHP etc. I dont think these languages will be needed in Game Development. In that case, what languages shall I focus on from now? How do I get some ideas about IDE/Engines/Platform of game development? I'm not talking about flash/browser games. Please suggest me anything you want as I don't know much about it so I'm most likely to miss the most important questions. Feel free to make this thread a starter guide for those interested in perusing their career in game development. Post every relevant information. Thanks in Advance. EDIT: I can see a lot of people suggested to build a small project/game. If so, please suggest me how do I start a small game developing (maybe a clone to some existing small games ie pacman, brick game etc) from start to end.

• How to read reduce/shift conflicts in LR(1) DFA?

  - by greenoldman

  I am reading an explanation (awesome "Parsing Techniques" by D.Grune and C.J.H.Jacobs; p.293 in the 2nd edition) and I moved forward from my last question: How to get lookahead symbol when constructing LR(1) NFA for parser? Now I have such "problem" (maybe not a problem, but rather need of confirmation from some more knowledgeable people). The authors present state in LR(0) which has reduce/shift conflict. Then they build DFA for LR(1) for the same grammar. And now they say it does not have a conflict (lookaheads at the end): S -> E . eof E -> E . - T eof E -> E . - T - and there is an edge from this state labeled - but no labeled eof. Authors says, that on eof there will be reduce, on - there will be shift. However eof is for shift as well (as lookahead). So my personal understanding of LR(1) DFA is this -- you can drop lookaheads for shifts, because they serve no purpose now -- shifts rely on input, not on lookaheads -- and after that, remove duplicates. S -> E . eof E -> E . - T So the lookahead for reduce serves as input really, because at this stage (all required input is read) it is really incoming symbol right now. For shifts, the input symbols are on the edges. So my question is this -- am I actually right about dropping lookaheads for shifts (after fully constructing DFA)?

• I can't see how a mature agile team requires any *management*?

  - by ashy_32bit

  After a recent heated debate over Scrum, I realized my problem is that I think of management as a quite unnecessary and redundant activity in a fully agile team. I believe a mature Agile team does not require management or any non-technical decision making process of whatsoever. To my (apparently erring) eyes it is more than obvious that the only one suitable and capable of managing a mature development team is their coach (and that being the most technically competent colleague with proper communication skills). I can't imagine how a Scrum master can contribute to such a team. I am having a great difficulty realizing and understanding the value of such things as Scrum and manager as someone who is not a veteran developer but is well skilled in planning the production cycles when a coach exists in the team. What does that even mean? How on earth someone with no edge-skills of development can manage a highly technical team? Perhaps management here means something else? I see management as a total waste of time and a by-product of immaturity. In my understanding a mature team is fully self-managing. Apparently I'm mistaken since many great people say the contrary but I can't convince myself.

• How can I check myself when I'm the only one working on a project?

  - by Ricardo Altamirano

  I'm in between jobs in my field (unrelated to software development), and I recently picked up a temporary side contract writing a few applications for a firm. I'm the only person working on these specific applications. Are there ways I should be checking myself to make sure my applications are sound? I test my code, try to think of edge cases, generate sample data, use source control, etc. but since I'm the only person working on these applications, I'm worried I'll miss bugs that would easily be found in a team environment. Once I finish the application, either when I'm happy with it or when my deadline expires, the firm plans to use it in production. Any advice? Not to use a cliche, but as of now, I simply work "to the best of my ability" and hope that it's enough. Incidentally, I'm under both strict NDA's and laws about classified material, so I don't discuss the applications with friends who have actually worked in software development. (In case it's not obvious, I am not a software developer by trade, and even my experience with other aspects of information technology/computer science are limited and restrained to dabbling for the most part).
