  • Methodology to understanding JQuery plugin & API's developed by third parties

    - by Taoist
    I have a question about third party created JQuery plug ins and API's and the methodology for understanding them. Recently I downloaded the JQuery Masonry/Infinite scroll plug in and I couldn't figure out how to configure it based on the instructions. So I downloaded a fully developed demo, then manually deleted everything that wouldn't break the functionality. The code that was left allowed me to understand the plug in much greater detail than the documentation. I'm now having a similar issue with a plug in called JQuery knob. http://anthonyterrien.com/knob/ If you look at the JQuery Knob readme file it says this is working code: $(function() { $('.dial') .trigger( 'configure', { "min":10, "max":40, "fgColor":"#FF0000", "skin":"tron", "cursor":true } ); }); But as far as I can tell it isn't at all. The read me also says the Plug in uses Canvas. I am wondering if I am suppose to wrap this code in a canvas context or if this functionality is already part of the plug in. I know this kind of "question" might not fit in here but I'm a bit confused on the assumptions around reading these kinds of documentation and thought I would post the query regardless. Curious to see if this is due to my "newbi" programming experience or if this is something seasoned coders also fight with. Thank you. Edit In response to Tyanna's reply. I modified the code and it still doesn't work. I posted it below. I made sure that I checked the Google Console to insure the basics were taken care of, such as not getting a read-error on the library. <!DOCTYPE html> <meta charset="UTF-8"> <title>knob</title> <link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/themes/hot-sneaks/jquery-ui.css" type="text/css" /> <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.js" charset="utf-8"></script> <script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.21/jquery-ui.min.js"></script> <script src="js/jquery.knob.js"></script> <div id="button1">test </div> <script> $(function() { $("#button1").click(function () { $('.dial').trigger( 'configure', { "min":10, "max":40, "fgColor":"#FF0000", "skin":"tron", "cursor":true } ); }); }); </script>

  • The Minimalist Approach to Content Governance - Create Phase

    - by Kellsey Ruppel
     Originally posted by John Brunswick. In this installment of our Minimalist Approach to Content Governance we finally get to the fun part of the content creation process! Once the content requester has addressed the items outlined in the Request Phase it is time to setup and begin the production of content.   For this to be done correctly it is important the the content be assigned appropriate workflow and security information. As in our prior phase, let's take a look at what can be done to streamline this process - as contributors are focused on getting information to their end users as quickly as possible. This often means that details around how to ensure that the materials are properly managed can be overlooked, but fortunately there are some techniques that leverage our content management system's native capabilities to automatically take care of some of the details. 1. Determine Access Why - Even if content is not something that needs to restricted due to security reasons, it is helpful to apply access rights so that the content ends up being visible only to users that it relates to. This will greatly improve user experience. For instance, if your team is working on a group project many of your fellow company employees do not need to see the content that is being worked on for that project. How - Make use of native content features that allow propagation of security and meta data from parent folders within your content system that have been setup for your particular effort. This makes it painless to enforce security, as well as meta data policies for even the most unorganized users. The default settings at a parent level can be set once the content creation request has been accepted and a location in the content management system is assigned for your specific project. Impact - Users can find information will less effort, as they will only be exposed to what they need for their work and can leverage advanced search features to take advantage of meta data assigned to content. The combination of default security and meta data will also help in running reports against the content in the Manage and Retire stages that we will discuss in the next 2 posts. 2. Assign Workflow (optional depending on nature of content) Why - Every case for workflow is going to be a bit different, but it generally involves ensuring that content conforms to management, legal and or editorial requirements. How - Oracle's Universal Content Management offers two ways of helping to workflow content without much effort. Workflow can be applied to content based on Criteria acting on meta data or explicitly assigned to content with a Basic workflow. Impact - Any content that needs additional attention before release is addressed, allowing users to comment and version until a suitable result is reached. By using inheritance from parent folders within the content management system content can automatically be given the right security, meta data and workflow information for a particular project's content. This relieves the burden of doing this for every piece of content from management teams and content contributors. We will cover more about the management phase within the content lifecycle in our next installment.

  • Training v. Teaching

    - by Chris Gardner
    Originally posted on: http://geekswithblogs.net/freestylecoding/archive/2014/05/28/training-v.-teaching.aspxAs some of you may know, I recently accepted a position to teach an undergraduate course at my alma mater. Yesterday, I had my first day in an academic classroom. I immediately noticed a difference with the interactions between the students. They don't act like students in a professional training or conference talk. I wanted to use this opportunity to enumerate some of those differences. The immediate thing I noticed was the lack of open environment. This is not to say the class was hostile towards me. I am used to entering the room, bantering with audience, loosening everyone a bit, and flowing into the discussion. A purely academic audience does not banter. At least, they do not banter on day one. I think I can attribute this to two factors. This first is a greater perception of authority. In a training or conference environment, I am an equal with the audience. This is true even if I am being a subject matter expert. We're all professionals. We're all there to learn from each other, share our stories, and enjoy the journey. In the academic classroom, there was a distinct class difference. I had forgotten about this distinction; I had the professional familiarity with the staff by the time I completed my masters. This leads to the other distinction. These was an expectation of performance. At conference and professional training, there is generally no (immediate) grading. This may be a preparation for a certification exam, but I'm not the one responsible for delivering the exam. This was not the case in the academic classroom. These students are battling for points, and I am the sole arbiter. These students are less likely to let the material wash over them, applying the material to their past experiences. They were down taking notes. I don't want to leave the impression that there was no interact in the classroom. I spent a good deal of time doing problems with the class on the whiteboard. I tried to get the class to help me work out the steps. This opened up a few of them. After every conference or training class, I always get a few people that will email me afterward to continue the conversation. I am very curious to see if anybody comes to my office hours tomorrow. However, that is a curiosity that will have to wait until tomorrow.

  • what would be a good way to implement/render a 2d tiled map for a browser game?

    - by jj_
    I've made this little rpg ruby game I did while learning and now I'd like to make it into a browser game. I've already set up Sinatra framework to serve it, so what I am looking for, before everything else, is a way to represent the game map in browser (location attributes are stored in db). A new map is randomly generated by code for each new game at each game start. For now forget db, and let's say a map (say 100x100 "squares") is stored as a tridimensional array. (x,y, ...) Last "dimension" of array stores who & what is at that map cell: a player, a building, whatever. So all I have to do is render those "squares" or array cells to a 2d tiled map in the browser. The map does not need to refresh or be dynamically fetched as you scroll it, (at least at this stage of development) but, a technology which would allow me to do so in future would be a good reason for choosing it. Things that I thought of: html tables, html5 canvas, some js framework which is designed exactly with this purpose (which I do not know of = please advice). Yes I know about gamequery-js framework, but I've never used it, and I don't know if it's going to slow down everything down to inusability as I'm adding new features (scrolling, ajax). I really don't know of any other alternatives.. maybe there are lighter approaches? Easier or more minimalistic ways ? More targeted js framework which is the right tool for the job? Maybe just some html canvas code, or even simple image maps, or images with absolute positioning will be enough? The thing is I'd like to start simple, and then gradually make it better, so, as I said before, I'd prefer something that will give me room for improvement or is headed toward new web tendencies but which will also give me a bit of gratification in the beginning :) So.. advices are needed! And appreciated! :) Thanks p.s. Flash is excluded because I don't like it.

  • Jitter during wall collisions with Bullet Physics: contact/penetration tolerance?

    - by Niriel
    I use the bullet physics engine through Panda3d. My scene is still very simple, think 'Wolfenstein3d': tile-based, walls are solid cubes. I expect walls to block the player, and I expect the player to slide along the walls in case of non-normal incidence. What I get is what I expect, with one difference: there is some jitter. If I try to force myself into the wall, then I see the frames blinking quickly between two positions. These differ by about 0.04 units of distance, which corresponds to 4 cm in my game. I noticed a 4 cm elsewhere: the bottom of my player capsule is 4 cm below ground, when at rest. Does that mean that there is somewhere in the Bullet engine a default 0.04-units-long tolerance to differentiate contact from collision? If so, what should I do ? Should I change the scale of my game so that these 0.04 units correspond to 0.4 cm, making the jitter ten times smaller? Or can I ask bullet to change its tolerance to a smaller value? Edit This is the jitter I get: 6.155 - 6.118 = 0.036 LPoint3f(0, 6.11694, 0.835) LPoint3f(0, 6.15499, 0.835) LPoint3f(0, 6.11802, 0.835) LPoint3f(0, 6.15545, 0.835) LPoint3f(0, 6.11817, 0.835) LPoint3f(0, 6.15726, 0.835) LPoint3f(0, 6.11876, 0.835) LPoint3f(0, 6.15911, 0.835) LPoint3f(0, 6.11937, 0.835) I found a setMargin method. I set it to 5 mm both on the BoxShape for the walls and on the Capsule shape for the player. It still jitters by about 35 mm as illustrated by this log (11.117 - 11.082 = 0.035): LPoint3f(0, 11.0821, 0.905) LPoint3f(0, 11.1169, 0.905) LPoint3f(0, 11.082, 0.905) LPoint3f(0, 11.117, 0.905) LPoint3f(0, 11.082, 0.905) LPoint3f(0, 11.117, 0.905) LPoint3f(0, 11.0821, 0.905) LPoint3f(0, 11.1175, 0.905) LPoint3f(0, 11.0822, 0.905) LPoint3f(0, 11.1178, 0.905) LPoint3f(0, 11.0823, 0.905) LPoint3f(0, 11.1183, 0.905) The margin on the capsule did change my penetration with the floor though, I'm a bit higher (0.905 instead of 0.835). However, it did not change anything when colliding with the walls. How can I make the collisions against the walls less jittery? Edit, the day after: After more investigation, it appears that dynamic objects behave well. My problem comes from the btKinematicCharacterController that I use for moving my character; that stuff is totally bugged, according to the whole Internet :/.

  • Got Samba, Got PyNeighbourhood but still no connection. What else do I need?

    - by Frank A
    I am sure I had already hit post before but then could only find it by backing through browser. Was it deleted? is the question too dumb, sorry that I do not know the right jargon just trying to get answers to my problem anyway have reworded stuff a bit This seems to be a number one requirement for lots of people and 2 months on from setting up my Ubuntu pc, I am still unable to get a lasting connection in either direction. Adding a windows pc to a network is so easy... just a few clicks and get on with using it all. Using all command approaches and modifying configuration files is hardly user friendly. Googling brings up thousands of solutions but mostly they are too techy or assume the user is fully aware of how to use Linux. I do realise that their must be a lot of flavours for connecting to networks. So far I have installed Samba and fiddled with its config file. The day I did all that it worked from XP to Ubuntu. When I came back two days later to transfer my data over it would not connect. Although the the share does show up in Windows (XP) My Network Places. Today I installed PyNeighbourhood and this shows the Ubuntu box and all of the shares I had created at some point on Ubuntu and it even shows this under the XP workgroup name. But instructions on setting the connection up seem to relate to an earlier version and nothing seems to work there either. (I unshared most of those test folders but they still show up her but that is another question. When I click on mount- I can only click on one on the Ubuntu machine, there is one with no name so I assume this to be my attempt to add one XP Shared drive using ipaddress, I get errors. (gksu:9767): Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap", (gksu:9767): Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap", (gksu:9767): Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap", (gksu:9767): Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap", mount error(6): No such device or address Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) OK tried to find the manual referred to... only an old comment that manual would be produced for future versions. I saw in another thread that Winbind is needed as well or at least I assume as well? Totally lost again? Please help, what else needs to be installed to connect to win pcs on the network.

  • New ZFS Encryption features in Solaris 11.1

    - by darrenm
    Solaris 11.1 brings a few small but significant improvements to ZFS dataset encryption.  There is a new readonly property 'keychangedate' that shows that date and time of the last wrapping key change (basically the last time 'zfs key -c' was run on the dataset), this is similar to the 'rekeydate' property that shows the last time we added a new data encryption key. $ zfs get creation,keychangedate,rekeydate rpool/export/home/bob NAME PROPERTY VALUE SOURCE rpool/export/home/bob creation Mon Mar 21 11:05 2011 - rpool/export/home/bob keychangedate Fri Oct 26 11:50 2012 local rpool/export/home/bob rekeydate Tue Oct 30 9:53 2012 local The above example shows that we have changed both the wrapping key and added new data encryption keys since the filesystem was initially created.  If we haven't changed a wrapping key then it will be the same as the creation date.  It should be obvious but for filesystems that were created prior to Solaris 11.1 we don't have this data so it will be displayed as '-' instead. Another change that I made was to relax the restriction that the size of the wrapping key needed to match the size of the data encryption key (ie the size given in the encryption property).  In Solaris 11 Express and Solaris 11 if you set encryption=aes-256-ccm we required that the wrapping key be 256 bits in length.  This restriction was unnecessary and made it impossible to select encryption property values with key lengths 128 and 192 when the wrapping key was stored in the Oracle Key Manager.  This is because currently the Oracle Key Manager stores AES 256 bit keys only.  Now with Solaris 11.1 this restriciton has been removed. There is still one case were the wrapping key size and data encryption key size will always match and that is where they keysource property sets the format to be 'passphrase', since this is a key generated internally to libzfs and to preseve compatibility on upgrade from older releases the code will always generate a wrapping key (using PKCS#5 PBKDF2 as before) that matches the key length size of the encryption property. The pam_zfs_key module has been updated so that it allows you to specify encryption=off. There were also some bugs fixed including not attempting to load keys for datasets that are delegated to zones and some other fixes to error paths to ensure that we could support Zones On Shared Storage where all the datasets in the ZFS pool were encrypted that I discussed in my previous blog entry. If there are features you would like to see for ZFS encryption please let me know (direct email or comments on this blog are fine, or if you have a support contract having your support rep log an enhancement request).

  • Unable to find good parameters for behavior of a puck in Farseer

    - by Krumelur
    EDIT: I have tried all kinds of variations now. The last one was to adjust the linear velocity in each step: newVel = oldVel * 0.9f - all of this including your proposals kind of work, however in the end if the velocity is little enough, the puck sticks to the wall and slides either vertically or horizontally. I can't get rid of this behavior. I want it to bounce, no matter how slow it is. Retitution is 1 for all objects, Friction is 0 for all. There is no gravity. What am I possibly doing wrong? In my battle to learn and understand Farseer I'm trying to setup a simple Air Hockey like table with a puck on it. The table's border body is made up from: Vertices aBorders = new Vertices( 4 ); aBorders.Add( new Vector2( -fHalfWidth, fHalfHeight ) ); aBorders.Add( new Vector2( fHalfWidth, fHalfHeight ) ); aBorders.Add( new Vector2( fHalfWidth, -fHalfHeight ) ); aBorders.Add( new Vector2( -fHalfWidth, -fHalfHeight ) ); FixtureFactory.AttachLoopShape( aBorders, this ); this.CollisionCategories = Category.All; this.CollidesWith = Category.All; this.Position = Vector2.Zero; this.Restitution = 1f; this.Friction = 0f; The puck body is defined with: FixtureFactory.AttachCircle( DIAMETER_PHYSIC_UNITS / 2f, 0.5f, this ); this.Restitution = 0.1f; this.Friction = 0.5f; this.BodyType = FarseerPhysics.Dynamics.BodyType.Dynamic; this.LinearDamping = 0.5f; this.Mass = 0.2f; I'm applying a linear force to the puck: this.oPuck.ApplyLinearImpulse( new Vector2( 1f, 1f ) ); The problem is that the puck and the walls appear to be sticky. This means that the puck's velocity drops to zero to quickly below a certain velocity. The puck gets reflected by the walls a couple of times and then just sticks to the left wall and continues sliding downwards the left wall. This looks very unrealistic. What I'm really looking for is that a puck-wall-collision does slow down the puck only a tiny little bit. After tweaking all values left and right I was wondering if I'm doing something wrong. Maybe some expert can comment on the parameters?

  • How can I be prepared to join a company?

    - by Aerovistae
    There's more to it than that, but this title was the best way I could think of to sum it up. I'm a senior in a good computer science program, and I'm graduating early. About to start interviews and all whatnot. I'm not a super-experienced programmer, not one of those people who started in middle school. I'm decent at this, but I'm not among the best, not nearly. I have to do an awful lot of googling. So today I'm meeting some fellow for lunch at a campus cafe to discuss some front-end details when this tall, good-looking guy begs pardon, says he's new to campus, says he's wondering if we know where he can go to sign up for recruiting developers. Quickly evolves into long conversation: he's the CEO of a seems-to-be-doing-well start-up. Hiring passionate interns and full-times. Sounds great! I take one look at his site on my own computer later, immediately spot a major bug. No idea how to fix it, but I see it. I go over to the page code, and good god. It's the standard amount of code you would expect from a full-scale web application, a couple dozen pages of HTML and scripts. I don't even know where to start reading it. I've built sites from scratch, but obviously never on that scale, nor have I ever worked on one of that scale. I have no idea which bit might generate the bug. But that sets me thinking: How could someone like me possibly settle into an environment like that? A start-up is a very high-pressure working environment. I don't know if I can work at that pace under those constraints-- I would hate to let people down. And with only 10 employees, it's not like anyone has much time to help you get your bearings. Somewhere in there is a question. Can you see it? I'm asking for general advice here. Maybe even anecdotal advice. Is joining a start-up right out of college a scary process? Am I overestimating what it would take to figure out the mass of code behind this site? What's the likelihood a decent but only moderately-experienced coder could earn his pay at such a place? For instance, I know nothing of server-side/back-end programming. Never touched it. That scares me.

  • Assessing Relative Maintainability

    - by João Bragança
    We (a contractor, actually) are implementing an off the shelf system to replace a legacy homegrown system for the core domain of the company (designing widgets). Unfortunately both systems will have to run concurrently for some time, as the product just isn't ready yet. Also, the decision was made to only migrate some of the widgets from the legacy system, based on date of last sale activity. Later on a new requirement came down: certain people in the company, most of them outside of the widget development context, want to search all widgets. The search results screen has 3 pieces of data: a GUID, a human readable id that is searchable, and a brief description (may need to be searchable in the future). In the widget details, there will be multiple screens. These screens align very well along SOA / bounded context lines - a screen for marketing data, a screen for sales history, etc. UML ahead! I am probably using the wrong kind of arrows here so please forgive me. The current solution - which is not in production yet - is something like the following: Both systems will be queried and the controller will merge the results. The new system has its own proprietary query language (we've alleviated this a bit with a LINQ provider). It also puts a lot of data on the wire. 15 search results typically run about 60k of unintelligible SOAP-wrapped xml. So I would prefer to avoid querying this system directly. These two systems publish events to help us integrate with other systems, mainly an ERP system. One of these events contains all the data necessary for the search screen. I proposed the following alternative: However I am being told that 'adding another database' will create more maintenance down the road. However, I believe this to be false, as I had to add a relatively simple feature that took several hours longer than anticipated because of this merging code. I want to get a feel for which system is more maintainable in the long run. I personally have not had the burden of maintaining any large system. I want something more than my gut. Specifically I'd like to know if having more, specialized physical databases is more or less maintainable than having less larger physical databases.

  • fdisk shows overlapping partitions

  • Profiling Startup Of VS2012 &ndash; Ants Profiler

    - by Alois Kraus
    I just downloaded ANTS Profiler 7.4 to check how fast it is and how deep I can analyze the startup of Visual Studio 2012. The Pro version which is useful does cost 445€ which is ok. To measure a complex system I decided to simply profile VS2012 (Update 1) on my older Intel 6600 2,4GHz with 3 GB RAM and a 32 bit Windows 7. Ants Profiler is really easy to use. So lets try it out. The Ants Profiler does want to start the profiled application by its own which seems to be rather common. I did choose Method Level timing of all managed methods. In the configuration menu I did want to get all call stacks to get full details. Once this is configured you are ready to go.   After that you can select the Method Grid to view Wall Clock Time in ms. I hate percentages which are on by default because I do want to look where absolute time is spent and not something else.   From the Method Grid I can drill down to see where time is spent in a nice and I can look at the decompiled methods where the time is spent. This does really look nice. But did you see the size of the scroll bar in the method grid? Although I wanted all call stacks I do get only about 4 pages of methods to drill down. From the scroll bar count I would guess that the profiler does show me about 150 methods for the complete VS startup. This is nonsense. I will never find a bottleneck in VS when I am presented only a fraction of the methods that were actually executed. I have also tried in the configuration window to also profile the extremely trivial functions but there was no noticeable difference. It seems that the Ants Profiler does filter away way too many details to be useful for bigger systems. If you want to optimize a CPU bound operation inside NUnit then Ants Profiler is with its line level timings a very nice tool to work with. But for bigger stuff it is certainly not usable. I also do not like that I must start the profiled application from the profiler UI. This makes it hard to profile processes which are started by some other process. Next: JetBrains dotTrace

  • Small script to look for Project Replication actions that have failed

    - by Trond Strømme
    Today when looking at a couple of projects on a ZFS 7320 Storage Appliance I noticed on one project that one of its replication actions had failed, as I hadn't checked the Recent Alerts log yet I was not aware of this. I decided to write a small script to check if there were others that had failed. Nothing fancy, just a loop through all projects, look at the project's replication child and compare the values of the last_sync and last_try properties and print the result if they're not equal. (There are probably more sensible ways of doing this, but at least it involves me getting the chance to put on my headphones and doing just a little bit of coding.) script // this script will locate failed project level replication // it will look at the sync times for 'last_sync' and 'last_try' // and compare these, if they deviate you should investigate. // NOTE! this code is offered 'as is' Run at your own risk, // it will probably work as intended, but in now way can I // (or Oracle) be held responsible if your server starts behaving // like a three year old kid in a candy store.. (not that mine do, // they are very well behaved boys...) run('configuration'); run('storage'); printf('Host: %s, pool: %s\n', get('owner'),get('pool')); run('cd /'); run('shares'); proj=list(); printf("total projects: %d\n",proj.length +'\n'); // just for project level replication for(i=0;i<proj.length;i++){ run('select '+proj[i]); run('replication'); //get all replication actions preps = list(); for(j=0;j<preps.length;j++){ run('select ' + preps[j]); last_sync = get('last_sync'); last_try = get('last_try'); // printf("target %s\n", get('target')); //why the flip does this not get the proper name? if(!( last_sync.valueOf() === last_try.valueOf())){ printf("sync has failed for %s %s\n", proj[i], get('target')); }else{ // printf("OK %s %s\n", proj[i], get('target')); } run('done'); //done with the replica action } run('done'); run('done'); } printf("finished\n"); For a more on how to run the script, or testing it please look at my previous post. Sample output: Host: elb1sn01, pool: exalogic total projects: 45 sync has failed for ACSExalogicSystem cb3a24fe-ad60-c90f-d15d-adaafd595639 finished

  • So, I though I wanted to learn frontend/web development and break out of my comfort zone...

    - by ripper234
    I've been a backend developer for a long time, and I really swim in that field. C++/C#/Java, databases, NoSql, caching - I feel very much at ease around these platforms/concepts. In the past few years, I started to taste end-to-end web programming, and recently I decided to take a job offer in a front end team developing a large, complex product. I wanted to break out of my comfort zone and become more of an "all around developer". Problem is, I'm getting more and more convinced I don't like it. Things I like about backend programming, and missing in frontend stuff: More interesting problems - When I compare designing a server that handle massive data, to adding another form to a page or changing the validation logic, I find the former a lot more interesting. Refactoring refactoring refactoring - I am addicted to Visual Studio with Resharper, or IntelliJ. I feel very comfortable writing code as it goes without investing too much thought, because I know that with a few clicks I can refactor it into beautiful code. To my knowledge, this doesn't exist at all in javascript. Intellisense and navigation - I hate looking at a bunch of JS code without instantly being able to know what it does. In VS/IntelliJ I can summon the documentation, navigate to the code, climb up inheritance hiererchies ... life is sweet. Auto-completion - Just hit Ctrl-Space on an object to see what you can do with it. Easier to test - With almost any backend feature, I can use TDD to capture the requirements, see a bunch of failing tests, then implement, knowing that if the tests pass I did my job well. With frontend, while tests can help a bit, I find that most of the testing is still manual - fire up that browser and verify the site didn't break. I miss that feeling of "A green CI means everything is well with the world." Now, I've only seriously practiced frontend development for about two months now, so this might seem premature ... but I'm getting a nagging feeling that I should abandon this quest and return to my comfort zone, because, well, it's so comfy and fun. Another point worth mentioning in this context is that while I am learning some frontend tools, a lot of what I'm learning is our company's specific infrastructure, which I'm not sure will be very useful later on in my career. Any suggestions or tips? Do you think I should give frontend programming "a proper chance" of at least six to twelve months before calling it quits? Could all my pains be growing pains, and will they magically disappear as I get more experienced? Or is gaining this perspective is valuable enough, even if plan to do more "backend stuff" later on, that it's worth grinding my teeth and continuing with my learning?

  • Switch from back-end to front-end programming: I'm out of my comfort zone, should I switch back?

  • Alert: It is No Longer 1982, So Why is CRM Still There?

    - by Mike Stiles
    Hot off the heels of Oracle’s recent LinkedIn integration announcement and Oracle Marketing Cloud Interact 2014, the Oracle Social Cloud is preparing for another big event, the CRM Evolution conference and exhibition in NYC. The role of social channels in customer engagement continues to grow, and social customer engagement will be a significant theme at the conference. According to Paul Greenberg, CRM Evolution Conference Chair, author, and Managing Principal at The 56 Group, social channels have become so pervasive that there is no longer a clear reason to make a distinction between “social CRM” and traditional CRM systems. Why not? Because social is a communication hub every bit as vital and used as the phone or email. What makes social different is that if you think of it as a phone, it’s a party line. That means customer interactions are far from secret, and social connections are listening in by the hundreds, hearing whether their friend is having a positive or negative experience with your brand. According to a Mention.com study, 76% of brand mentions are neutral, neither positive nor negative. These mentions fail to get much notice. So think what that means about the remaining 24% of mentions. They’re standing out, because a verdict, about you, is being rendered in them, usually with emotion. Suddenly, where the R of CRM has been lip service and somewhat expendable in the past, “relationship” takes on new meaning, seriousness, and urgency. Remarkably, legions of brands still approach CRM as if it were 1982. Today, brands must provide customer experiences the customer actually likes (how dare they expect such things). They must intimately know not only their customers, but each customer, because technology now makes personalized experiences possible. That’s why the Oracle Social Cloud has been so mission-oriented about seamlessly integrating social with sales, marketing and customer service interactions so the enterprise can have an actionable 360-degree view of the customer. It’s the key to that customer-centricity we hear so much about these days. If you’re attending CRM Evolution, Chris Moody, Director of Product Marketing for the Oracle Marketing Cloud, will show you how unified customer experiences and enhanced customer centricity will help you attract and keep ideal customers and brand advocates (“The Pursuit of Customer-Centricity” Aug 19 at 2:45p ET) And Meg Bear, Group Vice President for the Oracle Social Cloud, will sit on a panel talking about “terms of engagement” and the ways tech can now enhance your interactions with customers (Aug 20 at 10a ET). If you can’t be there, we’ll be doing our live-tweeting thing from the @oraclesocial handle, so make sure you’re a faithful follower. You’ll notice NOBODY is writing about the wisdom of “company-centricity.” Now is the time to bring your customer relationship management into the socially connected age. @mikestilesPhoto: Sue Pizarro, freeimages.com

  • It's possible to fulfill the social necessity of a human being through a social game in 3D like IMVU?

    - by Totty
    (I'm not advertising nor promoting this game, as it's just an example of my experience and I would like to have your opinion about the matter if possible) I've been started researching "things" about games and I've decided to begin to play IMVU as a friend of mine said it's cool. At first it seemed just another 3d social game, not so cool.. But I've "tried to like" and after 1 day I can say I'm addicted to it! Yes; I will explain better: About the game: You can go in chat-rooms, move to positions. Some positions are like sitting in a sofa, floor, dancing alone or with a partner, kissing and more in this way. In the free version of the game there is no nudity. You can even listen to music, view youtube... The 3d graphics are quite low end, so it's not as real as the paid PC games of today. About my experience: At first I was going with my friend in chat-rooms, they seemed very nice. There were people talking about general stuff, quite like in a real life. Well, I begin to know some girls (yes, virtual girls commanded by a real girl, I hope!). Things happened: Some girls are just crazy, not like in real life, they make out in before even talking; Other girls you can speak a little bit, then they add you to their friend-list. Sometimes they invite to their virtual places. Some girls have really IMVU boyfriends only (but not in reality) and most of them don't even make up in the game, so it's really a level of commitment involved here! But from what my friend told they last for him, at least, about 3 days... Some others have real and IMVU boyfriends that are the same. Until now I haven't find a girl with different boyfriend in the IMVU and reality. Nor multiple boyfriends. There are rooms where the same people find each selves every day and speak about general stuff, relationships and so on... They are nice with you, they "feel" you and show careness. This is what amazes me, they treat you like a real human being and as being their friend in the real world. (of course it's not always like this) There are jealous girls too and competitiveness between females lol, I know you loled! This is kind of social. So today I closed my door in my room and I've played it all day long and guess what, I didn't feel a need to stay with a real person at all. Normally, If I would stay a full day alone I would get quite crazy... So the question is: It's just me that seemed to be able to fulfill my social needs or there is something more? thanks for your precious time for reading my full question,

  • What arguments can I use to "sell" the BDD concept to a team reluctant to adopt it?

    - by S.Robins
    I am a bit of a vocal proponent of the BDD methodology. I've been applying BDD for a couple of years now, and have adopted StoryQ as my framework of choice when developing DotNet applications. Even though I have been unit testing for many years, and had previously shifted to a test-first approach, I've found that I get much more value out of using a BDD framework, because my tests capture the intent of the requirements in relatively clear English within my code, and because my tests can execute multiple assertions without ending the test halfway through - meaning I can see which specific assertions pass/fail at a glance without debugging to prove it. This has really been the tip of the iceberg for me, as I've also noticed that I am able to debug both test and implementation code in a more targeted manner, with the result that my productivity has grown significantly, and that I can more easily determine where a failure occurs if a problem happens to make it all the way to the integration build due to the output that makes its way into the build logs. Further, the StoryQ api has a lovely fluent syntax that is easy to learn and which can be applied in an extraordinary number of ways, requiring no external dependencies in order to use it. So with all of these benefits, you would think it an easy to introduce the concept to the rest of the team. Unfortunately, the other team members are reluctant to even look at StoryQ to evaluate it properly (let alone entertain the idea of applying BDD), and have convinced each other to try and remove a number of StoryQ elements from our own core testing framework, even though they originally supported the use of StoryQ, and that it doesn't impact on any other part of our testing system. Doing so would end up increasing my workload significantly overall and really goes against the grain, as I am convinced through practical experience that it is a better way to work in a test-first manner in our particular working environment, and can only lead to greater improvements in the quality of our software, given I've found it easier to stick with test first using BDD. So the question really comes down to the following: What arguments can I use to really drive the point home that it would be better to use StoryQ, or at the very least apply the BDD methodology? Can you point me to any anecdotal evidence that I can use to support my argument to adopt BDD as our standard method of choice? What counter arguments can you think of that could suggest that my wish to convert the team efforts to BDD might be in error? Yes, I'm happy to be proven wrong provided the argument is a sound one. NOTE: I am not advocating that we rewrite our tests in their entirety, but rather to simply start working in a different manner for all future testing work.

  • C# Preprocessor Directives

    - by MarkPearl
    Going back to my old c++ days at university where we had all our code littered with preprocessor directives - I thought it made the code ugly and could never understand why it was useful. Today though I found a use in my C# application. The scenario – I had made various security levels in my application and tied my XAML to the levels by set by static accessors in code. An example of my XAML code for a Combobox to be enabled would be as follows… <ComboBox IsEnabled="{x:Static security:Security.SecurityCanEditDebtor}" />   And then I would have a static method like this… public static bool SecurityCanEditDebtorPostalAddress { get { if (SecurityCanEditDebtorPostalAddress) { return true; } else { return false; } } } My only problem was that my XAML did not like the if statement – which meant that while my code worked during runtime, during design time in VS2010 it gave some horrible error like… NullReferenceException was thrown on “StatiucExtension”: Exception has been thrown by the target of an invocation… If however my C# method was changed to something like this… public static bool SecurityCanEditDebtorPostalAddress { get { return true; } }   My XAML viewer would be happy. But of course this would bypass my security… <Drum Roll> Welcome preprocessor directives… what I wanted was during my design experience to totally remove the “if” code so that my accessor would return true and not have any if statements, but when I release my project to the big open world, I want the code to have the is statement. With a bit of searching I found the relevant MSDN sample and my code now looks like this… public static bool SecurityCanEditDebtorPostalAddress { get { #if DEBUG return true; #else if (Settings.GetInstance().CurrentUser.SecurityCanEditDebtorPostalAddress) { return true; } else { return false; } #endif } }   Not the prettiest beast, but it works. Basically what is being said here is that during my debug mode compile my code with just the code between the #if … #else block, but what I can now do is if I want to universally switch everything to the “if else” statement, I just go to my project properties –> Build and change the “Debug” flag as illustrated in the picture below. Also note that you can define your own conditional compilation symbols, and if you even wanted to you could skip the whole properties page and define them in code using the #define & #undef directives. So while I don’t like the way the code works and would like to look more into AOP and compare it to this method, it works for now.

  • How to apply effects that occur (or change) over time to characters in a game?

    - by Joshua Harris
    So assume that I have a system that applies Effects to Characters like so: public class Character { private Collection<Effect> _effects; public void AddEffect (Effect e) { e.ApplyTo(this); _effects.Add(e); } public void RemoveEffect (Effect e) { e.RemoveFrom(this); _effects.Remove(e); } } public interface Effect { public void ApplyTo (Character character); public void RemoveFrom (Character character); } Example Effect: Armor Buff for 5 seconds. void someFunction() { // Do Stuff ... Timer armorTimer = new Timer(5 seconds); ArmorBuff armorbuff = new ArmorBuff(); character.AddEffect(armorBuff); armorTimer.Start(); // Do more stuff ... } // Some where else in code public void ArmorTimer_Complete() { character.RemoveEffect(armorBuff); } public class ArmorBuff implements Effect { public void applyTo(Character character) { character.changeArmor(20); } public void removeFrom(Character character) { character.changeArmor(-20); } } Ok, so this example would buff the Characters armor for 5 seconds. Easy to get working. But what about effects that change over the duration of the effect being applied. Two examples come to mind: Damage Over Time: 200 damage every second for 3 seconds. I could mimic this by applying an Effect that lasts for 1 second and has a counter set to 3, then when it is removed it could deal 200 damage, clone itself, decrement the counter of the clone, and apply the clone to the character. If it repeats this until the counter is 0, then you got a damage over time ability. I'm not a huge fan of this approach, but it does describe the behavior exactly. Degenerating Speed Boost: Gain a speed boost that degrades over 3 seconds until you return to your normal speed. This is a bit harder. I can basically do the same thing as above except having timers set to some portion of a second, such that they occur fast enough to give the appearance of degenerating smoothly over time (even though they are really just stepping down incrementally). I feel like you could get away with only 12 steps over a second (maybe less, I would have to test it and see), but this doesn't seem very elegant to me. The only other way to implement this effect would be to change the system so that the Character checks the _effects collection for effects that alter any of the properties any time that they are being used. I could handle this in functions like getCurrentSpeed() and getCurrentArmor(), but you can imagine how much of a hassle it would be to have that kind of overhead every time you want to do a calculation with movement speed (which would be every time you move your character). Is there a better way to deal with these kinds of effects or events?

  • Ubuntu Linux won't display netbook's native resolution

    - by Daniel
    FYI: My Netbook model is HP Mini 210-1004sa, which comes with Intel Graphics Media Accelerator 3150, and has a display 10.1" Active Matrix Colour TFT 1024 x 600. I recently removed Windows 7 Starter from my netbook, and replaced it with Ubuntu 12.10. The problem is the OS doesn't seem to recognise the native display resolution of 1024x600 i.e. the bottom bits of Ubuntu is hidden beneath the screen & the only 2 available resolutions are: the default 1024x768 and 800x600. I've also thought about replacing Ubuntu with Lubuntu or Puppy Linux, as the system does run a bit slow, but I can't, as then I won't be able to access the taskbar and application menu which will be hidden beneath the screen. Only Ubuntu with Unity is currently usable, as the Unity Launcher is visible enough. I was able to define a custom resolution 1024x600 using the Q&A: How set my monitor resolution? but when I set that resolution, there appears a black band at the top of the screen and the desktop area is lowered, with bits of it hidden beneath the screen. I tried leaving it at this new resolution and restarting the system to see if the black band would disappear & the display will fit correctly, but it gets reset to 1024x768 at startup and displays following error: Could not apply the stored configuration for monitors none of the selected modes were compatible with the possible modes: Trying modes for CRTC 63 CRTC 63: trying mode 800x600@60Hz with output at 1024x600@60Hz (pass 0) CRTC 63: trying mode 800x600@56Hz with output at 1024x600@60Hz (pass 0) CRTC 63: trying mode 640x480@60Hz with output at 1024x600@60Hz (pass 0) CRTC 63: trying mode 1024x768@60Hz with output at 1024x600@60Hz (pass 1) CRTC 63: trying mode 800x600@60Hz with output at 1024x600@60Hz (pass 1) CRTC 63: trying mode 800x600@56Hz with output at 1024x600@60Hz (pass 1) CRTC 63: trying mode 640x480@60Hz with output at 1024x600@60Hz (pass 1) Trying modes for CRTC 64 CRTC 64: trying mode 1024x768@60Hz with output at 1024x600@60Hz (pass 0) CRTC 64: trying mode 800x600@60Hz with output at 1024x600@60Hz (pass 0) CRTC 64: trying mode 800x600@56Hz with output at 1024x600@60Hz (pass 0) CRTC 64: trying mode 640x480@60Hz with output at 1024x600@60Hz (pass 0) CRTC 64: trying mode 1024x768@60Hz with output at 1024x600@60Hz (pass 1) CRTC 64: trying mode 800x600@60Hz with output at 1024x600@60Hz (pass 1) CRTC 64: trying mode 800x600@56Hz with output at 1024x600@60Hz (pass 1) CRTC 64: trying mode 640x480@60Hz with output at 1024x600@60Hz (pass 1)

  • What You Said: Staying Productive While Working from home

    - by Jason Fitzpatrick
    Earlier this week we asked you to share your telecommuting/work-from-home productivity tips. Now we’re back with a tips and tricks roundup; read on to see how your fellow readers stay focused at home. By far and away the most common technique deployed as carefully isolating work from home life. Carol writes: I love working from home and have done so for 6 years now. I have a routine just as if I was going to an office, except my commute is 12 steps. I get ready for work, grab my purse and smart phone and go to up the steps to my office. I maintain a separate phone line and voice mail for work that I cannot answer from anywhere but my work desk. I use call forwarding when I travel so only my office phone number is published. I have VOIP phone service so I can forward calls from the internet if I forget, or need to change where the phone is forwarded. I do have a wired and wireless head set so I can go get a cold drink if on one of those long boring conference calls. I plan my ‘get off from work’ time and try to stick to it, as with any job some days I am late getting off, but it all works out. I make sure my office is for work only, any other computer play time is in a different part of the house on different computer. My office has laptop, dock, couple of monitors, multipurpose printer, fax, scanner, file cabinets – just like the office at a company. I just also happen to have a couple of golden retrievers that come to work with me and usually lay quietly until 5, and yes they know it is 5pm sometimes before I do. For me, one of the biggest concerns when working from home is not being unproductive, but the danger of never stopping work. You could keep going and going because let’s face it – the company will let you do it, so I set myself up to prevent that and maintain a separateness.

  • My First 5K, the recap.

    - by Chris Williams
    It was a nice day to be outside (and trust me, those aren't words you'll hear from me often.) I got to the site around 7:45, hit the pre-reg table and got my number along with a goody bag full of coupons for racing gear, a water bottle and a tshirt. Oh and a map. Stashed all that stuff in the jeep, emptied my pockets of everything but my iPhone and my jeep key, and proceeded to walk around for a bit as people started showing up and signing in. It was fairly breezy, and there was definitely a storm coming... but it was anyone's guess on when it would actually arrive. It was interesting to see everyone who was participating. If I had to guess, I would say the event was 60-70% women, with a pretty broad distribution of age... as young as 13 to well over 60 (in both genders.) I don't know exactly how many folks were there, but it was well over 300. Eventually it was time to kick things off, and everyone made their way to the start line. All of the 5k and 10k runners were mixed together, starting at the same time. All the walkers and the people with strollers or dogs were in the back. It was pretty chaotic at first, once things started, but it thinned out fairly quickly. The 10k people and the hardcore runners sped ahead of everyone else and the walkers gradually lagged behind. The 5K course was pretty nice, winding around a lake down in Eden Prairie. The 10K course overlapped most of ours, but branched off a couple times too. I didn't run the whole time, but I started the race running and I ended it running, and did a mix of walking and running along the way. I met my goals, which were a) don't ever stop and b) don't be last. The weather managed to hold out for the entire race. It never got too hot, there was a nice breeze and it was mostly overcast. Pretty much perfect in my book. About 20-30 minutes after I left, the rain came down pretty hard. I had a good time, and will most likely do more of them. We'll see.

  • How to explain bad software to non-technical people?

    - by mtutty
    In discussing software development with non-technical people (customers, business owners, project sponsors, etc.), I often resort to analogies and metaphors. It's relatively easy and effective to use a "house" or other metaphor for describing the size and complexity of new development. However, we often inherit someone else's code or data, and this approach doesn't seem to hold up as well when trying to explain why we're gutting something that already seems to work. Of course we can point to cycle time and cost to be saved in the future but this generally means nothing to business folks. I know doctors can say "just take this pill," but I'm not sure that software devs have the same authority. Ideas? EDIT: Let me add a bit to the discussion. The specific project I'm talking about has customers that don't realize (or care) about specific aspects of the system we're retiring (i.e., they think it was just fine): The system would save a NEW RECORD every time someone updated a field The system contained tables for reference data. These tables had new records added every day, even though they were duplicates of previous records. And there was no way to tie the reference data used for a particular case at the time it was closed. This is like 99% of the data in the old system. The field NAMES also have spaces, apostrophes and other inappropriate characters in them, making everything harder to work with. In addition to the incredible amount of duplicate data, they have around 1000 XLS files with data they want added to the system. Previously, they would do a spreadsheet for each case in the database, IN ADDITION TO what they typed into the database. Getting rid of this old, unneeded information and piping in the XLS data comprises about 80% of the total project effort, and was not something we could accurately predict. I'm trying to find a concrete way to describe how bad this thing was, mostly so that the customer will understand why the migration process has been so time-consuming. The actual coding was done pretty quickly and the new system works fine, but without the old data they won't be happy. Sorry to get into the weeds, but most of the answers I've seen so far are pretty basic scope/schedule/cost things. I've been doing this for 15 years, so this really is more of a reflective, philosophical question - but without some of the details it can be difficult to really appreciate the awful beauty of this problem.

  • What's about Java?

    - by Silviu Turuga
    What is Java? In very short words, Java is a programming language that let you make an application that can be run on different operating systems, no matter we are talking about Windows, Mac OS, Linux or even embedded devices, such as RaspberryPi. When you compile a Java program, instead of getting a binary output as you get on other programming languages, you'll get a Java intermediate code, called Java bytecode. This is interpreted at run time, by a virtual machine that is specifically for the hardware and operating system you are using. What Java do i need? There are 5 major versions of Java: Java SE(Standard Edition) - this is what I'll use on most of my tutorials. Most of the examples will run on Java 6, but for others you'll need Java 7.
