• How to work with Firefox nightly build [minefield]

  - by anirudha

  Most of developer love Firefox for their plugin who support for making development easier and faster. many of us use Firefox nightly build aka minefield who update daily. there is a little problem in minefield that there is less plugin on addons site of mozilla for Firefox nightly [minefield]. a solution for this problem is that you need to install the plugin who you want in nightly build from the developer site instead of add-ons site of Mozilla. the reason for that is all many of popular plugin in development for support Firefox 4. How to install follow the thing as mine : go to minefield > addons or toolbar  > addons you see a list of plugin who is not suitable for minefield now go to more link of plugin who you want to get work in Firefox 4. When you click their you go to plugin page on addons site of mozilla or maybe redirect you to developer site. if they show you plugin page then go to developer site by click on link more about developer. now you find that on the developer site they give you the same version or maybe new then you found on mozilla addons site. install the plugin and restart the minefield. you see that most of plugin now work.

• Is there any reason not to go directly from client-side Javascript to a database?

  - by Chris Smith

  So, let's say I'm going to build a Stack Exchange clone and I decide to use something like CouchDB as my backend store. If I use their built-in authentication and database-level authorization, is there any reason not to allow the client-side Javascript to write directly to the publicly available CouchDB server? Since this is basically a CRUD application and the business logic consists of "Only the author can edit their post" I don't see much of a need to have a layer between the client-side stuff and the database. I would simply use validation on the CouchDB side to make sure someone isn't putting in garbage data and make sure that permissions are set properly so that users can only read their own _user data. The rendering would be done client-side by something like AngularJS. In essence you could just have a CouchDB server and a bunch of "static" pages and you're good to go. You wouldn't need any kind of server-side processing, just something that could serve up the HTML pages. Opening my database up to the world seems wrong, but in this scenario I can't think of why as long as permissions are set properly. It goes against my instinct as a web developer, but I can't think of a good reason. So, why is this a bad idea? EDIT: Looks like there is a similar discussion here: Writing Web "server less" applications EDIT: Awesome discussion so far, and I appreciate everyone's feedback! I feel like I should add a few generic assumptions instead of calling out CouchDB and AngularJS specifically. So let's assume that: The database can authenticate users directly from its hidden store All database communication would happen over SSL Data validation can (but maybe shouldn't?) be handled by the database The only authorization we care about other than admin functions is someone only being allowed to edit their own post We're perfectly fine with everyone being able to read all data (EXCEPT user records which may contain password hashes) Administrative functions would be restricted by database authorization No one can add themselves to an administrator role The database is relatively easy to scale There is little to no true business logic; this is a basic CRUD app

• Which shopping cart / ecommerce platform to choose?

  - by fabien7474

  I need to build an ecommerce website within a tight budget and schedule. Of course, I have never done that before, so I have googled out what my solutions are and I have concluded that the following were not valid candidates anymore : Magento : Steep learning curve osCommerce : old, bad design, buggy and not user-friendly Zencart, CRE Loaded, CubeCart : based on osCommerce Virtuemart, uberCart, eCart : based on CMS (Joomal, Drupal, WordPress) that is not necessary for my use-case So I finally narrowed down my choices to these solutions : PrestaShop : easy-to-use, great templating engine (smarty) but many modules are not free buy yet indispensable OpenCart : security issues and not a great support from the main developer. See here and here. So, as you can see, I am a little bit confused and if you can help me choosing an easy-to-use, lightweight and cheap (not-necessarily free) ecommerce solution, I would really appreciate. By the way, I am a Java/Grails programmer but I am also familiar with PHP and .NET. (not with Python or Ruby/Rails) EDIT: It seems that this question is more appropriate for the Webmaster StackExchange site. So please move this question to where it belongs (I cannot do that) instead of downvoting it. BTW, I have found out a question quite similar on SO (http://stackoverflow.com/questions/3315638/php-ecommerce-system-which-one-is-easiest-to-modify) which is quite popular.

• Are programmers a bunch of heartless robots who are lacking of empathy? [closed]

  - by Graviton

  OK, the provocative title got your attention. My experience as a programmer and dealing with my fellow programmers is that, a programmer is also usually someone who is so consumed by his programming work, so absorbed in his algorithmic construction that he has little passion/ time left for anything else, which includes empathy for other people, love and care for the people whom he love or should love ( such as their spouses, parents, kids, colleagues etc). The better a person is in terms of his programming powers, the more defective he is in terms of love/care because both honing programming skills and loving the surrounding takes time and one has only so much time to be allocated among so many different things. Also, programming ( especially INTERESTING programming job, like, writing an AI to predict the future search trend) is a highly consuming job; it doesn't just consume you from 9 to 5, it will also consume you after 5 and practically every second of your waking hours because a good programmer can't just magically switch off his thinking hat after the office lights go off ( If you can then I don't really think you are a passionate programmer, and the prerequisite of a good programmer is passion). So, a good programmer is necessarily someone who can't love as much as others do because the very nature of the programming job prevents him from loving others as much as he wants to. Do you concur with my observation/ reasoning?

• Turn off Windows Defender on your builds

  - by george_v_reilly

  I've spent some time this evening profiling a Python application on Windows, trying to find out why it was so much slower than on Mac or Linux. The application is an in-house build tool which reads a number of config files, then writes some output files. Using the RunSnakeRun Python profile viewer on Windows, two things immediately leapt out at me: we were running os.stat a lot and file.close was really expensive. A quick test convinced me that we were stat-ing the same files over and over. It was a combination of explicit checks and implicit code, like os.walk calling os.path.isdir. I wrote a little cache that memoizes the results, which brought the cost of the os.stats down from 1.5 seconds to 0.6. Figuring out why closing files was so expensive was harder. I was writing 77 files, totaling just over 1MB, and it was taking 3.5 seconds. It turned out that it wasn't the UTF-8 codec or newline translation. It was simply that closing those files took far longer than it should have. I decided to try a different profiler, hoping to learn more. I downloaded the Windows Performance Toolkit. I recorded a couple of traces of my application running, then I looked at them in the Windows Performance Analyzer, whereupon I saw that in each case, the CPU spike of my app was followed by a CPU spike in MsMpEng.exe. What's MsMpEng.exe? It's Microsoft's antimalware engine, at the heart of Windows Defender. I added my build tree to the list of excluded locations, and my runtime halved. The 3.5 seconds of file closing dropped to 60 milliseconds, a 98% reduction. The moral of this story is: don't let your virus checker run on your builds.

• Who is code wanderer?

  - by DigiMortal

  In every area of life there are people with some bad habits or misbehaviors that affect the work process. Software development is also not free of this kind of people. Today I will introduce you code wanderer. Who is code wanderer? Code wandering is more like bad habit than serious diagnose. Code wanderers tend to review and “fix” source code in files written by others. When code wanderer has some free moments he starts to open the code files he or she has never seen before and starts making little fixes to these files. Why is code wanderer dangerous? These fixes seem correct and are usually first choice to do when considering nice code. But as changes are made by coder who has no idea about the code he or she “fixes” then “fixing” usually ends up with messing up working code written by others. Often these “fixes” are not found immediately because they doesn’t introduce errors detected by compilers. So these “fixes” find easily way to production environments because there is also very good chance that “fixed” code goes through all tests without any problems. How to stop code wanderer? The first thing is to talk with person and explain him or her why those changes are dangerous. It is also good to establish rules that state clearly why, when and how can somebody change the code written by other people. If this does not work it is possible to isolate this person so he or she can post his or her changes to code repository as patches and somebody reviews those changes before applying them.

• agile as our first project management methodology [closed]

  - by Hasan Khan

  we are a small web development company that has till now been working on client projects. we employed little to no project management and that has cost us a lot. we've used only the barest of tools (wireframing, prototyping etc) but no formal project management process has been put into place. we've learnt from our mistakes and want to prevent them from happening in the future. also, we are looking to develop our own products and we understand that putting in a proper project management paradigm will help. after a lot of research, we've sort of settled on agile for a few reasons: agile seems to scale well with team size. our team is small right now and we hope to grow and agile seems to be a process that we can put in place now and grow with. agile will help us with customers who just can't seem to make up their minds and keep changing requirements. we'd appreciate the community's thoughts on this. is this a correct way to think? will agile be a good system to put into place, where there has been none till now? are there any resources that may help us in our position? pretty much all of the resources that we've found start by comparing agile to x (where x = any management methodology) and why its better than x and how agile can be implemented in place of x. we're looking for resources that can help us out in our particular situation. thanks for all your help!

• The biggest ADF conference "down under"

  - by Chris Muir

  While Oracle Open World is the place to be for ADF presentations, for Aussies living in Perth, San Francisco is a tad far away (believe me from experience, the 23hrs flight from PER-SYD-SFO is tedious).  That's why I'm very excited to see that the Australian Oracle User Group at this year's Perth conference is running its largest set of ADF presentation to date: 5! Okay, it doesn't compare to the 60 ADF sessions at OOW, but it's a small conference of around 300 people that runs for 2 days with 54 sessions total, not 40000 people that runs for 5 days with 1900+ sessions, so I think that's a good effort for a conference that's at the end of the earth! What's even better about this year's conference, is the AUSOUG conference is moving away from just consultants and Oracle staff presenting, but will also include customers presenting on ADF too.  This again proves Perth is a little ADF hotspot, which puts a tear to an ADF product manager's eye let me tell you ;-) The ADF sessions will include: Kevin Payne - JWH Group - ADF Mobile Application Development Matthew Carrigy - Department of Finance Western Australia - The times, they are a-changin’ - An Oracle Forms to JDeveloper ADF  Case Study Penny Cookson & Chris Noonan - Sage Computing Services - Impress your bosses with JDeveloper ADF dashboards on their iPads ...oh and... Chris Muir - Oracle Corporation - Speed-Dating Oracle JDeveloper 12c and Oracle ADF New Features  Chris Muir - Oracle Corporation - Develop Mobile Apps for Smart Devices: Converging Web and Native Applications You can check out the conference schedule here.  I hope you'll support these ADF presenters by attending the AUSOUG Perth conference, I look forward to seeing you there.

• How to explain pointers to a Java/VB programmer

  - by Skeith

  I am writing a game and my friend has offered to help me as it is a RPG and will take a long time to do the "scripting" bit of the game. The problem is IMO he's not that good a programmer :( (add flame war here). He has only programmed in Java and VB and keeps saying really stupid things to me like "Why don't you drag and drop an onClick event" to design my UI when I'm using DirectX. I tried explaining pointers to him but his response was, if it's just a variable that holds a memory address, why don't you just use an int? I create an instance of an attack class and give the creature a pointer to it so if several creatures use the same attack there is only one instance of it. He keeps saying why not put if statements in the creature class for every attack class and set true for the ones that are there. He has programmed mainly in VB and a little in Java just to learn OOP. How can I explain advanced C++ concepts like pointers and memory management to him? He just doesn't understand there are no super functions like form.show in C++.

• XNA Masking Mayhem

  - by TropicalFlesh

  I'd like to start by mentioning that I'm just an amateur programmer of the past 2 years with no formal training and know very little about maximizing the potential of graphics hardware. I can write shaders and manipulate a multi-layered drawing environment, but I've basically stuck to minimalist pixel shaders. I'm working on putting dynamic point light shadows in my 2d sidescroller, and have had it working to a reasonable degree. Just chucking it in without working on serious optimizations outside of basic culling, I can get 50 lights or so onscreen at once and still hover around 100 fps. The only issue is that I'm on a very high end machine and would like to target the game at as many platforms I can, low and high end. The way I'm doing shadows involves a lot of masking before I can finally draw the light to my light layer. Basically, my technique to achieveing such shadows is as follows. See pics in this album http://imgur.com/a/m2fWw#0 The dark gray represents the background tiles, the light gray represents the foreground tiles, and the yellow represents the shadow-emitting foreground tile. I'll draw the light using a radial gradient and a color of choice I'll then exclude light from the mask by drawing some geometry extending through the tile from my point light. I actually don't mask the light yet at this point, but I'm just illustrating the technique in this image Finally, I'll re-include the foreground layer in my mask, as I only want shadows to collect on the background layer and finally multiply the light with it's mask to the light layer My question is simple - How can I go about reducing the amount of render target switches I need to do to achieve the following: a. Draw mask to exclude shadows from the foreground to it's own target once per frame b. For each light that emits shadows, -Begin light mask as full white -Render shadow geometry as transparent with an opaque blendmode to eliminate shadowed areas from the mask -Render foreground mask back over the light mask to reintroduce light to the foreground c. Multiply light texture with it's individual mask to the main light layer.

• Cannot move/drag/drop windows/items in remote VNC session

  - by hansioux

  I find it a little hard to believe that no one here has asked this question, I tried searching for it but it isn't asked, so here goes: I setup a Ubuntu desktop computer with VNC to use as a server. And use another Ubuntu desktop computer to VNC into it. The rest of the VNC works ok, but drag and drop with mouse is gone. Thus I can not move windows, or drag and drop items via VNC. I am using the default remote desktop in System - Preferences to setup my server. And use Remmina as my client. The same happens using MS Windows's VNC clients connecting to my Ubuntu desktop. I did a bit of searching on google, and there are actually a lot of reports regarding this issue. But, oddly there is no solution. There are even bug reports made for this since Ubuntu 9.10, yet here it still is in Ubuntu 11.04. There have been suggestions that the bugs is in gtk, as see in link below: http://ubuntuforums.org/showthread.php?t=1497635&page=2 libgtk2.0-0 stable(lenny) -> DnD works libgtk2.0-0 lenny-backport (libgtk2.0-0_2.18.6-1~bpo50+1_i386) -> DnD still works libgtk2.0-0 testing (libgtk2.0-0_2.20.1-2_i386) -> DnD broken please don't give answers such as "use NX", "use ssh -x" or "use x11vnc". I am aware that some people don't have this problem with x11vnc, and I have setup x11vnc before, but i can't for this setup. I am setting this up so Windows only friends/families can use it.

• Newbie seeking advice on programming in general

  - by user974685

  need some of you to remember back to a time when you might have been bad at programming... Been at my new job (as a software developer) for a couple of months now, passed probation period. Have very little programming experience (C++ only) and am currently working with asp.net MVC and silverlight. So there's a website the company has been working on and I am joining the effort to make it better, iron out bugs etc. The problem is - learning about a system/website which has already been made, via visual studio. I ALWAYS feel HUGELY overwhelmed, never knowing which part of this line should I look up, and generally having lots of trouble getting the big picture. Visual studio itself is something I'm finding it difficult to get to grips with, let alone the asp.net framework. I get the impression that because my coworkers have more experience than me, they are getting all the good jobs, and I am left with crap to do - stuff which is not even vaguely programming. Meaning they are learning/creating more, and I am learning/creating near nothing. I'm getting demoralised, and too scared to say anything. I'm not stupid, I've read and practiced plenty of the fundamental programming concepts...I'm just bloody scared of this damn framework. I look at it and just feel paralyzed. The result is that I keep asking the older veteran guy of questions, and he is getting irritated, and would rather give me easy/mindless/non programming jobs to avoid wasting time with helping me out. Then when I don't understand something, I'm hesitating about whether or not I should ask him yet, and trying to decide if it would be a waste of time. I'm the kind of person who picks things up slowly, but with a lot of attention to detail. The former I think is making me look incompetent though. Anyone get where I'm coming from please say something helpful....I'm scared of losing my job in a few months or something...

• Java web app, with plugin framework and ability to connect to source for updates

  - by lessthancommon

  I've searched all around for some good sources, but either have been searching for the wrong keywords, or I'm just missing something. I'm looking to redevelop a web app I've been using for some time now. Many parts are out of date, and we're constantly throwing in little hacks to attempt to give it new life. So what I'd like to do is re-engineer it from the ground up, built on some sort of plug-in framework. Before I continue, I'm more or less an intermediate Java programmer. In some ways, I'm hoping to use this project as a big learning experience. I've read a lot about OSGi, and it seems that's the most complete framework. Ideally, I would like an end result web app which I can run one instance as my hosting environment, and other instances can connect to it to grab new and updated plug-ins. Eventually I'll want to lock down these plug-ins based on some undecided criteria of who can get them (basically some will simply be updates, others will provide new functionality and should be "purchased" through an external system). But that will probably be handled in a later phase. There should be an administration view for managing bundles in a hot environment (looking to avoid having to restart the server for an update). I know all these things are possible, I'm just trying to find some good resources for reference. All the OSGi tutorials I'm finding seem to be too simplistic. If anyone here can guide me in the right direction on any or all of the items I'm looking for, it would be much appreciated. Also, this is my first post, so I'll take any comments/criticisms about the content of my post. Thanks!

• Spring Roo Database Reverse Engineer with Oracle

  - by kerry

  So you are trying to reverse engineer an Oracle database with roo? Unfortunately, due to licensing restrictions with the Oracle JDBC Drivers, this is a little difficult. There are a few blog posts and forum threads that address the problem but I figured I would post what worked for me here. First, you need to download the appropriate Oracle Drivers from Oracle. The required login, stringent password requirements, nosy registration form, and general system instability made this a pretty painful step for me. I’d also like to say that companies that have password requirements that don’t allow symbols (or any other non-standard requirement) have a special place in my heart. Having to recover my password every time I go to your site virtually guarantees I will only go there when I absolutely have to (not often). Anyways, once you have it downloaded you need to install is with maven: mvn install:install-file -Dfile=~/Downloads/ojdbc6.jar -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.0.3 -Dpackaging=jar -DgeneratePom=true Here comes the fun part. You need to create an osgi wrapper for the driver to install it in roo. Otherwise, roo cannot see the driver. Create a new folder and put the contents of the oracle roo addon pom gist I created. Now build it with maven. You may want to change some of the artifact ids and dependencies for your particular situation. mvn package No open a roo shell and execute the following command: osgi install --url file:///Users/me/my-osgi-project/target/the-jar-it-built.jar Now run (in roo): jpa setup --provider HIBERNATE --database ORACLE dependency remove --groupId com.oracle --artifactId ojdbc14 --version 10.2.0.2 dependency add --groupId com.oracle --artifactId ojdbc6 --version 11.2.0.3 database properties set --key database.driverClassName --value oracle.jdbc.OracleDriver database properties set --key database.url --value jdbc:oracle:thin:@%YOUR_CONNECTION_INFO% database properties set --key database.username --value %YOUR_USERNAME% database properties set --key database.password --value %YOUR_PASSWORD% database reverse engineer --schema %YOUR_SCHEMA% --package ~.domain If you have any package loading exceptions when running the reverse engineer command you can uninstall the osgi bundle, set the package to optional in the osgi pom in the IncludedPackages tag (javax.some.package.*;resolution:=optional) rebuild, then reinstall in roo.

• How would I implement this application idea?

  - by Mike Wills

  I am a D&D gamer and a developer that has mostly worked with ASP.NET applications professionally. I have written some chat bots in Node.js and I have only played a little with PHP but wrote nothing serious. I have had inspiration to create a site that allows a person to keep track of characters (aka the character sheet). I am thinking of using this as a learning opportunity to learn noSQL and to write a full javascript front-end. I want this application to save the value as I change it. So if I edit the armor class, it is saved immediately instead of waiting until I hit the submit button. I think that will make it easier to use while gaming and not losing anything because I forgot to save the change. I have never done anything like this. How do you implement this style of application? Is there a tutorial or howto to get me on the right path? While I would really like to use ASP.NET but I don't have a Windows server to publish on (and I really can't afford to pay for a service). What language that runs on Linux would work well for this type of application? Note: I feel noSQL would work in this case because of the sheer number of tables required to create something like this in SQL.

• Intelligence as a vector quantity

  - by Senthil Kumaran

  I am reading this wonderful book called "Coders at Work: Reflections on the Craft of Programming" by Peter Seibel and I am at part wherein the conversation is with Joshua Bloch and I found this answer which is an important point for a programmer. The paragraph, goes something like this. There's this problem, which is, programming is so much of an intellectual meritocracy and often these people are the smartest people in the organization; therefore they figure they should be allowed to make all the decisions. But merely the fact they are the smartest people in the organization does not mean that they should be making all the decisions, because intelligence is not a scalar quantity; it's a vector quantity. Here at the last sentence, I fail to get the insight which is he trying to share. Can someone explain it in a little further as what he means by a vector quantity, possibly trying to present the same insight. Further down, I get the point that he is not taking about having an organization where non-technical people (sometimes clueless) can be managers of the technical people for some reason that they can spend more time to write emails well, because the very next statement following the above paragraph was. And if you lack empathy or emotional intelligence, then you shouldn't be designing APIs or GUIs or languages. I understand that he is saying that in Software engineering, programmers should know how the users will see their product and design for them. I felt the above paragraph was very interesting.

• Announcing IIS Community Newsletter

  - by steve schofield

  I'm excited to announce a newsletter for the IIS community is available.  Here is the link to signup.  The goal is to cover all happenings in the IIS community.  The goal is to have a monthly newsletter.  Sign-up for IIS Community Newsletterhttp://www.iislogs.com/newsletter/ A little history.  l previously was involved with Brett Hill and authoring the IIS Answers newsletter for about 1 year.  The newsletter literally reached thousands of IIS administrators providing up-to-date Microsoft and community related information.  It was an excellent source of information.  That is my goal with the IIS Community Newsletter. With everything, there is always some "geeking" that goes into it.  I'm using www.StarDeveloper.com newsletter application.   For a modest $10.00 fee, the application provides a simple, yet powerful way to manage newsletters.  I added a CAPTCHA feature to sign-up.  The CAPTCHA module I used was provided free by MONDOR software.  I personally never used one on a application and it was easy to implement.  Thanks for sharing!  Cheers, Steve SchofieldMicrosoft MVP - IIS

• Ignore Partial Upgrade -- Google Earth Dependencies

  - by pyraz

  I'm running a 64-bit install of Xubuntu 12.04. It took me a little while to get Google Earth working. The 64-bit Google earth package requires some 32-bit gtk libraries provided by ia32-libs. However, when I ran a simulation to install ia32-libs and it's dependencies, it wanted to remove a ton of programs, including the xubuntu-desktop meta-package. As a work-around, I used getlibs to get the 32-bit libraries I needed, and then installed Google Earth with the deb package and the --ignore-depend option to dpkg. Awesome, Google Earth is installed and is working great! Now, however, Update Manager keeps complaining about a "Partial Upgrade", and apt-get won't let me install any new applications. It wants me to do a fix-broken install, but when I do a simulation of apt-get -f install I get some very bad news, they want to uninstall the Google Earth I just worked so hard to install! $> apt-get -f -s install Reading package lists... Done Building dependency tree Reading state information... Done Correcting dependencies... Done The following packages will be REMOVED: googleearth 0 upgraded, 0 newly installed, 1 to remove and 0 not upgraded. Remv googleearth [6.0.3.2197+0.7.0-1] TL;DR The --ignore-depends passed to dpkg is not propagating to apt-get, so now I can't install any new applications until I uninstall Google Earth, because of it's missing dependencies (even though it works fine without them). How can I fix this?

• Handling SEO for Infinite pages that cause external slow API calls

  - by Noam

  I have an 'infinite' amount of pages in my site which rely on an external API. Generating each page takes time (1 minute). Links in the site point to such pages, and when a users clicks them they are generated and he waits. Considering I cannot pre-create them all, I am trying to figure out the best SEO approach to handle these pages. Options: Create really simple pages for the web spiders and only real users will fetch the data and generate the page. A little bit 'afraid' google will see this as low quality content, which might also feel duplicated. Put them under a directory in my site (e.g. /non-generated/) and put a disallow in robots.txt. Problem here is I don't want users to have to deal with a different URL when wanting to share this page or make sense of it. Thought about maybe redirecting real users from this URL back to the regular hierarchy and that way 'fooling' google not to get to them. Again not sure he will like me for that. Letting him crawl these pages. Main problem is I can't control to rate of the API calls and also my site seems slower than it should from a spider's perspective (if he only crawled the generated pages, he'd think it's much faster). Which approach would you suggest?

• App_offline.htm and SharePoint and wholly contained images&hellip;

  - by Shawn Cicoria

  The question came up today if we could use an “app_offline.htm” file along with HTML in that file that would reference images. First, I wasn’t 100% sure if the app_offline.htm would work, but it sure did.  Since it’s just the Asp.net hosting process that detects the file, it circumvents loading any HttpApplications (SharePoint) beyond just serving up the HTML content. The second question was about having something more than text, specifically <img> tags.  So, since the HttpHandlers are taking all requests for all resources through the Asp.net pipeline, as soon as the app_offline.htm file is there, nothing else will get served from within that web application.    Sure, we could host the file (images) outside the web app, but what fun would that be? So, I found this link on using an image in app_offline.htm http://pbodev.wordpress.com/2009/12/20/app_offline-htm-with-an-image-yes-we-can/ Turns out, the src tag (in fact many tags) can take a stream of data represented by a mime type and base64 encoding inline – such as: <img style="height:515px;width:700px;border-width:0px;" src="data:image/jpeg;base64,/9j/4AAQSkZJRgA   One of the problems we had was the image was too large; so, sliced up the image, but ended up with spaces between each of the slices.  Low and behold, it works with CSS as well.   <style type="text/css"> .Slice_1_jpg { position: absolute; left:0px; top:0px; width:1011px; height:148px; background: url("data:image/jpeg;base64,/9j/4AAQSkZ   And the body is as follows: <body> <div class="Slice_1_jpg"> </div>   For this, I wrote a little Asp.Net site that, using a file upload control, will generate the necessary contents of what needs to go in the “data” value for the stream.  A link to the code is here: http://cicoria.com/downloads/CreateBase64OfImage.zip

• C4C - 2012

  - by Timothy Wright

  C4C, in Kansas City, is always a fun event. At points it gets to be a pressure cooker as you zone in trying to crank out some fantastic code in just a few hours, but it is always fun. A great challenge of your skill as a software developer and for a good cause. This year my team helped The United Cerebral Palsy of Greater Kansas City organization to add online job applications and a database for tracking internal training. I keep finding that there is one key rule to pulling off a successful C4C weekend project, and that is “Keep It Simple”. Each time you want to add that one cool little feature you have to ask yourself.. Is it really necessary? and Do I have time for that? And if you are going to learn something new you should ask yourself if you’re really going to be able to learn that AND finish the project in the given time. Sometimes the less elegant code is the better code if it works. That said… You get a great amount of freedom to build the solution the way you want. Typically, the software we build for the charities will save them a lot of money and time and make their jobs easier. You are able to build the software you know you are capable of creating from your own ideas. I highly recommend any developers in the area to signup next year and show off your skills. I know I will!

• How do graphics programmers deal with rendering vertices that don't change the image?

  - by canisrufus

  So, the title is a little awkward. I'll give some background, and then ask my question. Background: I work as a web GIS application developer, but in my spare time I've been playing with map rendering and improving data interchange formats. I work only in 2D space. One interesting issue I've encountered is that when you're rendering a polygon at a small scale (zoomed way out), many of the vertices are redundant. An extreme case would be that you have a polygon with 500,000 vertices that only takes up a single pixel. If you're sending this data to the browser, it would make sense to omit ~499,999 of those vertices. One way we achieve that is by rendering an image on a server and and sending it as a PNG: voila, it's a point. Sometimes, though, we want data sent to the browser where it can be rendered with SVG (or canvas, or webgl) so that it can be interactive. The problem: It turns out that, using modern geographic data sets, it's very easy to overload SVG's rendering abilities. In an effort to cope with those limitations, I'm trying to figure out how to visually losslessly reduce a data set for a given scale and map extent (and, if necessary, for a known map pixel width and height). I got a great reduction in data size just using the Douglas-Peucker algorithm, and I believe I was able to get it to keep the polygons true to within one pixel. Unfortunately, Douglas-Peucker doesn't preserve topology, so it changed how borders between polygons got rendered. I couldn't readily find other algorithms to try out and adapt to the purpose, but I don't have much CS/algorithm background and might not recognize them if I saw them.

• SEO Keyword Research Help

  - by James

  Hi Everyone, I'm new at SEO and keyword research. I am using Market Samurai as my research tool, and I was wondering if I could ask for your help to identify the best key word to target for my niche. I do plan on incorporating all of them into my site, but I wanted to start with one. If you could give me your input on these keywords, I would appreciate it. This is all new to me :) I'm too new to post pictures, but here are my keywords (Searches, SEO Traffic, and SEO Value / Day): Searches | SEO Traffic | PBR | SEO Value | Average PR/Backlinks of Current Top 10 1: 730 | 307 | 20% | 2311.33 | 1.9 / 7k-60k 2: 325 | 137 | 24% | 822.94 | 2.3 / 7k-60k 3: 398 | 167 | 82% | 589.79 | 1.6 / 7k-60k I'm wondering if the PBR (Phrase-to-broad) value of #1 is too low. It seems like the best value because the SEOV is crazy high. That is like $70k a month. #3 has the highest PBR, but also the lowest SEOV. #2 doesn't seem worth it because of the PR competetion. Might be a little too hard to get into the top page of Google. I'm wondering which keywords to target, and if I should be looking at any other metric to see if this is a profitable niche to jump into. Thanks.
