  • What Color is your Jetpack ?

    - by JoshReuben
    I’m a programmer, Im approaching 40, and I’m fairly decent at my job – I’ll keep doing what I’m doing for as long as they let me!   So what are your career options if you know how to code? A Programmer could be ..   An Algorithm developer Pros Interesting High barriers of entry, potential for startup competitive factor Cons Do you have the skill, qualifications? What are working conditions n this mystery niche ? micro-focus An Academic Pros Low pressure Job security – or is this an illusion ? Cons Low Pay Need a PhD A Software Architect Pros: strategic, rather than tactical Setting technology platform and high level vision You say how it should work, others have to figure out why its not working the way its supposed to ! broad view – you are paid to learn (how do you con people into paying for you to learn ??) Cons: Glorified developer – more often than not! competitive – everyone wants to do it ! loose touch with underlying tech in tough times, first guy to get the axe ! A Software Engineer Pros: interesting, always more to learn fun I can do it Fallback Cons: Nothing new under the sun – been there, done that Dealing with poor requirements, deadlines, other peoples code, overtime C#, XAML, Web - Low barriers of entry –> à race to the bottom A Team leader Pros: Setting code standards and proposing technology choices Cons: Glorified developer – more often than not! Inspecting other peoples code and debugging the problems they cannot fix Dealing with mugbies and prima donas Responsible for QA of others A Project Manager Pros No need for debugging other peoples code Cons Low barrier of entry High pressure Responsible for QA of others Loosing touch with technology A lot of bullshit meetings Have to be an asshole A Product Manager Pros No need for debugging other peoples code Learning new skillset of sales and marketing Cons Travel (I'm a family man) May need to know the bs details of an uninteresting product things I want to work with: AI, algorithms, Numerical Computing, Mathematica, C++ AMP – unfortunately, the work here is few & far between. VS & TFS Extensibility, DSLs (Workflow , Lightswitch), Code Generation – one day, code will write code ! Unity3D, WebGL – fun, fun, fun ! Modern Web – Knockout, SignalR, MVC, Node.Js ??? (tentative – I'll wait until things stabilize as this area is undergoing a pre-Cambrian explosion) Things I don’t want to work with: (but will if I'm asked to !) C# – same old, same old – not learning anything new here Old code – blech ! Environment with code & fix mentality , ad hoc requirements, excessive overtime Pc support, System administration – even after 20 years, people still ask you to do this sometimes ! debugging – my skills are just not there yet Oracle Old tech: VB 6, XSLT, WinForms, Net 3.51 or less Old style Web dev Information Systems: ASP.NET webforms, Reporting services / crystal reports, SQL Server CRUD with manual data layer, XAML MVVM – variations of the same concept, ad nauseaum. Low barriers of entry –> race to the bottom.  Metro – an elegant API coupled to a horrendous UX – I'll wait for market penetration viability before investing further in this.   Conclusion So if you are in a slump, take heart: Programming is a great career choice compared to every other job !

  • We have our standards, and we need them

    - by Tony Davis
    The presenter suddenly broke off. He was midway through his section on how to apply to the relational database the Continuous Delivery techniques that allowed for rapid-fire rounds of development and refactoring, while always retaining a “production-ready” state. He sighed deeply and then launched into an astonishing diatribe against Database Administrators, much of his frustration directed toward Oracle DBAs, in particular. In broad strokes, he painted the picture of a brave new deployment philosophy being frustratingly shackled by the relational database, and by especially by the attitudes of the guardians of these databases. DBAs, he said, shunned change and “still favored tools I’d have been embarrassed to use in the ’80′s“. DBAs, Oracle DBAs especially, were more attached to their vendor than to their employer, since the former was the primary source of their career longevity and spectacular remuneration. He contended that someone could produce the best IDE or tool in the world for Oracle DBAs and yet none of them would give a stuff, unless it happened to come from the “mother ship”. I sat blinking in astonishment at the speaker’s vehemence, and glanced around nervously. Nobody in the audience disagreed, and a few nodded in assent. Although the primary target of the outburst was the Oracle DBA, it made me wonder. Are we who work with SQL Server, database professionals or merely SQL Server fanbois? Do DBAs, in general, have an image problem? Is it a good career-move to be seen to be holding onto a particular product by the whites of our knuckles, to the exclusion of all else? If we seek a broad, open-minded, knowledge of our chosen technology, the database, and are blessed with merely mortal powers of learning, then we like standards. Vendors of RDBMSs generally don’t conform to standards by instinct, but by customer demand. Microsoft has made great strides to adopt the international SQL Standards, where possible, thanks to considerable lobbying by the community. The implementation of Window functions is a great example. There is still work to do, though. SQL Server, for example, has an unusable version of the Information Schema. One cast-iron rule of any RDBMS is that we must be able to query the metadata using the same language that we use to query the data, i.e. SQL, and we do this by running queries against the INFORMATION_SCHEMA views. Developers who’ve attempted to apply a standard query that works on MySQL, or some other database, but doesn’t produce the expected results on SQL Server are advised to shun the Standards-based approach in favor of the vendor-specific one, using the catalog views. The argument behind this is sound and well-documented, and of course we all use those catalog views, out of necessity. And yet, as database professionals, committed to supporting the best databases for the business, whatever they are now and in the future, surely our heart should sink somewhat when we advocate a vendor specific approach, to a developer struggling with something as simple as writing a guard clause. And when we read messages on the Microsoft documentation informing us that we shouldn’t rely on INFORMATION_SCHEMA to identify reliably the schema of an object, in SQL Server!

  • Any tips on getting hired as a software project manager straight out of college?

    - by MHarrison
    I graduated with a BS in compsci last September, and I've been trying (unsuccessfully) to find a job as a project manager ever since. I fell in love with software engineering (the formal practice behind it all, not just coding) in school, and I've dedicated the last 3-4 years of my life to learning everything I can about project management and gaining experience. I've managed several projects (with teams around 12 people) while in school, and I worked with my university's software engineering research lab. My résumé is also decent - I worked as a programmer before I went to school (I'm 27 now), and I did Google Summer of Code for 3 summers. I also have general "people management" experience via working as the photo editor for my university's newspaper for 2 years. My first problem with the job hunt is not getting enough interviews. I use careers.stackoverflow.com, which is awesome because I usually get contacted by non-HR people who know what they're talking about, but there's just not enough companies using it for me to get interviews on a regular basis. I've also tried sites like monster.com, and in a fit of desperation, I sent out no less than 60 applications to project management positions. I've gotten 3 automated rejection letters and that's it. At least careers.stackoverflow gets me a phone interview with 8/10 places I apply to. But the main (and extremely frustrating) problem is the matter of experience. I've successfully managed projects from start to finish (in my software engineering classes we had real customers come in with a real software need and we built it for them), but I've never had to deal with budgets and money (I know this is why HR people immediately turn me away). Most of these positions require 5+ years PM experience, and I've seen absurd things like 12+ years required. Interviews are also maddening. I've had so many places who absolutely loved me and I made it to the final round of interviews, and I left thinking things went extremely well and they'd consider me. However, when I check in with them a week later, they tell me "We really liked you and your qualifications are excellent, but we're hoping to find someone with more experience." The bad interviews I can understand - like the PM position that would have had me managing developers both locally and overseas - I had 3 interviews with them and the ENTIRE interview process was them asking me CS brainteasers and having me waste time on things like writing quicksort on paper or writing binary search trees. Even when I tried steering the discussion towards more relevant PM stuff, they gave me some vague generic replies and went back to the "We want to be Google/MS" crap. But when I have a GOOD interview, they say my "qualifications are excellent" but they want "more experience"...that makes me want to tear my hair out. What else can I DO? While I'm aiming for technically-involved PM positions (not just crunching budget numbers), I really don't want a straight development job because I like creating software from the very high-level vs. spending a lot of time debugging memory leaks. In fact, I can't even GET development positions that I'm qualified for because I make the mistake of telling them that my future career goals are as PM (which usually results in them saying something like "Well we already have PMs and this position isn't really set up to get you there." - which I take to mean "No, that's my job, stay away.") My apologies on the long rant, but I'm seriously hellbent on getting hired as a PM since it's both my career goal and the passion that keeps me awake at night. Any suggestions on what the heck else I can do? I'm currently writing a blog where I talk about my philosophies about software engineering, and I'm writing up specs for an iOS app which I will design, code, and show employers, but this takes an awful lot of time that I don't have.

  • New PeopleSoft HCM 9.1 On Demand Standard Edition provides a complete set of IT services at a low, predictable monthly cost

    - by Robbin Velayedam
    At Oracle Open World last month, Oracle announced that we are extending our On Demand offerings with the general availability of PeopleSoft On Demand Standard Edition. Standard Edition represents Oracle’s commitment to providing customers a choice of solutions, technology, and deployment options commensurate with their business needs and future growth. The Standard Edition offering complements the traditional On Demand offerings (Enterprise and Professional Editions) by focusing on a low, predictable monthly cost model that scales with the size of your business.   As part of Oracle's open cloud strategy, customers can freely move PeopleSoft licensed applications between on premise and the various  on demand options as business needs arise.    In today’s business climate, aggressive and creative business objectives demand more of IT organizations. They are expected to provide technology-based solutions to streamline business processes, enable online collaboration and multi-tasking, facilitate data mining and storage, and enhance worker productivity. As IT budgets remain tight in a recovering economy, the challenge becomes how to meet these demands with limited time and resources. One way is to eliminate the variable costs of projects so that your team can focus on the high priority functions and better predict funding and resource needs two to three years out. Variable costs and changing priorities can derail the best laid project and capacity plans. The prime culprits of variable costs in any IT organization include disaster recovery, security breaches, technical support, and changes in business growth and priorities. Customers have an immediate need for solutions that are cheaper, predictable in cost, and flexible enough for long-term growth or capacity changes. The Standard Edition deployment option fulfills that need by allowing customers to take full advantage of the rich business functionality that is inherent to PeopleSoft HCM, while delegating all application management responsibility – such as future upgrades and product updates – to Oracle technology experts, at an affordable and expected price. Standard Edition provides the advantages of the secure Oracle On Demand hosted environment, the complete set of PeopleSoft HCM configurable business processes, and timely management of regular updates and enhancements to the application functionality and underlying technology. Standard Edition has a convenient monthly fee that is scalable by number of employees, which helps align the customer’s overall cost of ownership with its size and anticipated growth and business needs. In addition to providing PeopleSoft HCM applications' world class business functionality and Oracle On Demand's embassy-grade security, Oracle’s hosted solution distinguishes itself from competitors by offering customers the ability to transition between different deployment and service models at any point in the application ownership lifecycle. As our customers’ business and economic climates change, they are free to transition their applications back to on-premise at any time. HCM On Demand Standard Edition is based on configurability options rather than customizations, requiring no additional code to develop or maintain. This keeps the cost of ownership low and time to production less than a month on average. Oracle On Demand offers the highest standard of security and performance by leveraging a state-of-the-art data center with dedicated databases, servers, and secured URL all within a private cloud. Customers will not share databases, environments, platforms, or access portals with other customers because we value how mission critical your data are to your business. Oracle’s On Demand also provides a full breadth of disaster recovery services to provide customers the peace of mind that their data are secure and that backup operations are in place to keep their businesses up and running in the case of an emergency. Currently we have over 50 PeopleSoft customers delegating us with the management of their applications through Oracle On Demand. If you are a customer interested in learning more about the PeopleSoft HCM 9.1 Standard Edition and how it can help your organization minimize your variable IT costs and free up your resources to work on other business initiatives, contact Oracle or your Account Services Representative today.

  • jqtouch / google maps api v3 issue

    - by Rigo Vides
    Hi everyone, I'm having a hard time triying to make jQtouch and Google Maps api V3 together. I've tried almost everything. It seems that the only source of information is here I checked every single post. I'm starting with jQuery and css... so there's a lot of stuff I don't understand. First of all, I'm using jQtouch framework to build a web app with google maps integration, the problem is that whenever I pan the map, strange flickering occurs. It's like jQtouch and the map are trying to fight for a callback. I'm using the latest revision out there. And have several bugs, regarding transition/animation functionality (since I don't wrap the map and all the element's divs within the #jqt wrapper) and css issues with some styling. Anyone has successfully achieve a functional setup build for this scenario? (google maps api v3 & jqtouch), I think is not necessary to paste you some code (But if you think is necessary please let me know and I'll do it), If you paste me a minimal example with a map (detailing jqtouch version, and modification to the styles/.js files), and some transition back and forth from the map to another div/section/page, you'll get the bounty. Thanks a lot in advance. And please, let me know if this is kind of 'legal' here, I mean, there's too loose information on the official wiki, and like 13 'solutions' but nothing concrete... I'm just triying to help anyone who step on in this problem in the future.

  • Finding string in php

    - by Roshan
    I have a content and i want to search a keyword in that content. Content When charting multiple data series, or just to improve the appearance of your charts, you can control the fill for each series in the chart or each item in a series. The fill lets you specify a pattern that defines how Flex draws the chart element. You also use fills to specify the background colors of the chart or bands of background colors defined by the grid lines. Fills can be solid or can use linear and radial gradients. A gradient specifies a gradual color transition in the fill color therefore. NOw, if the keyword we are searching is "When", it is the starting word so should display as "When charting multiple data ..........." If the keyword is "draws" , it lies in middle so should be displayed as ".... how Flex draws....." If the kewyword is "therefore", it is in the last position so should be displayed as ".........transition in the fill color therefore." Can anyone help me out how to do this in php server script?

  • H.264 / FLV best practices for HTML

    - by Steve Murch
    I run a website with about 700 videos (And no, it's not porn -- get your mind out of the gutter :-) ). The videos are currently in FLV format. We use the JWPlayer to render those videos. IIS6 hosted. Everything works just fine. As I understand it, H.264 (not FLV and likely not OGG) is the emerging preferred HTML5 video standard. Today, the iPad really only respects H.264 or YouTube. Presumably, soon many more important browsers will follow Apple's lead and respect only the HTML5 tag. OK, so I think I can figure out how to convert my existing videos into the proper H.264 format. There are various tools available, including ffmpeg.exe. I haven't tried it yet, but I don't think that's going to be a problem after fiddling with the codec settings. My question is more about the container itself -- that is, planning graceful transition for all users. What's the best-practice recommendation for rendering these videos? If I just use the HTML5 tag, then presumably any browser that doesn't yet support HTML5 won't see the videos. And if I render them in Flash format via the JWPlayer or some other player, then they won't be playable on the iPad. Do I have to do ugly UserAgent detection here to figure out what to render? I know the JWPlayer supports H.264 media, but isn't the player itself a Flash component and therefore not playable on the iPad? Sorry if I'm not being clear, but I'm scratching my head on a graceful transition plan that will work for current browsers, the iPad and the upcoming HTML5 wave. I'm not a video expert, so any advice would be most welcome, thanks.

  • Jquery Tools: Scrollable - onBeforeSeek & onSeek toggle child div

    - by Rick
    I'm scrolling some panels which contain some youtube clips using Jquery Tools Scrollable. I'd like to hide them during the transition to avoid a jerky animation. Markup: <div id="panel_items"> <div id="wrap"> <div class="event"> <div class="header">Event 1</div><!-- Header is always displayed --> <div class="youtube">youtube clips</div><!-- hide during transition, then show --> </div> <div class="event"> <div class="header">Event 2</div> <div class="youtube" style="display: none">More youtube clips</div> </div> </div> </div> Current JS: $("#panel_items").scrollable({ onBeforeSeek: function() { console.log("hide .child .youtube"); }, onSeek: function() { console.log("Show child .youtube"); } }); Bonus question: How can I automatically set the height of #panel_items to match the current panel height (.event)? Thank you.

  • SeriesInterpolate - removing data at start of array

    - by Allan Jardine
    Hello all, I've been experimenting with Flex Charts (in Flash Builder 4) recently, but have run into one area which didn't quite work as I was expecting. Specifically, when adding and removing a data point from an array, with SeriesInterpolate set. I've put up three examples, as I expect these will make a lot more sense than me trying to explain it with words only!: http://sprymedia.co.uk/media/misc/flex/linechart/LineChart-Add.swf - Clicking the button in the top right adds a new data point to the end of the data array, and the chart is smoothly updated (almost smoothly there is a 1px shift when animating which is odd...) http://sprymedia.co.uk/media/misc/flex/linechart/LineChart-Delete.swf - Clicking the button (which is now labelled incorrectly) will remove the item at the start of the data array - but the chart draws this as if it were removing the end element. http://sprymedia.co.uk/media/misc/flex/linechart/LineChart-AddDelete.swf - This is sort of what I'm eventually aiming for - a smooth side scroll chart, where new data is added at the end and the old data is sifted off the front. However the delete behaviour makes this look a bit odd. Does anyone know if there is a way to get the smooth transition I'm looking with SeriesInterpolate? Or is it possible to implement a custom transition? Many thanks, Allan

  • Having trouble animating Line in D3.js using and array of objects as data

    - by user1731245
    I can't seem to get an animated transition between line graphs when I pass in a new set of data. I am using an array of objects as data like this: [{ clicks: 40 installs: 10 time: "1349474400000" },{ clicks: 61 installs: 3 time: "1349478000000" }]; I am using this code to setup my ranges / axis's var xRange = d3.time.scale().range([0, w]), yRange = d3.scale.linear().range([h , 0]), xAxis = d3.svg.axis().scale(xRange).tickSize(-h).ticks(6).tickSubdivide(false), yAxis = d3.svg.axis().scale(yRange).ticks(5).tickSize(-w).orient("left"); var clicksLine = d3.svg.line() .interpolate("cardinal") .x(function(d){return xRange(d.time)}) .y(function(d){return yRange(d.clicks)}); var clickPath; function drawGraphs(data) { clickPath = svg.append("g") .append("path") .data([data]) .attr("class", "clicks") .attr("d", clicksLine); } function updateGraphs(data) { svg.select('path.clicks') .data([data]) .attr("d", clicksLine) .transition() .duration(500) .ease("linear") } I have tried just about everything to be able to pass in new data and see an animation between graph's. Not sure what I am missing? does it have something to do with using an array of objects instead of just a flat array of numbers as data?

  • Manually start session with specific id / transitioning session cookie between domains

    - by deceze
    My host requires me to use a different domain for SSL secured access (shared SSL), so I need to transition the user session between two domains. One part of the page lives at http://example.com, while the SSL'd part is at https://example.hosting.com. As such I can't set a domain-spanning cookie. What I'm trying to do is to transition the session id over and re-set the cookie like this: http://example.com/normal/page, user clicks link to secure area and goes to: http://example.com/secure/page, which causes a redirect to: https://example.hosting.com/secure/page?sess=ikub..., which resurrects the session and sets a new cookie valid for the domain, then redirects to: https://example.hosting.com/secure/page This works up to the point where the session should be resurrected. I'm doing: function beforeFilter() { ... $this->Session->id($_GET['sess']); $this->Session->activate(); ... } As far as I can tell this should start the session with the given ID. It actually generates a new session ID though and this session is empty, the data is not restored. This is on CakePHP 1.2.4. Do I need to do something else, or is there a better way to do what I'm trying to do?

  • Using Hidden Markov Model for designing AI mp3 player

    - by Casper Slynge
    Hey guys. Im working on an assignment, where I want to design an AI for a mp3 player. The AI must be trained and designed with the use of a HMM method. The mp3 player shall have the functionality of adapting to its user, by analyzing incoming biological sensor data, and from this data the mp3 player will choose a genre for the next song. Given in the assignment is 14 samples of data: One sample consist of Heart Rate, Respiration, Skin Conductivity, Activity and finally the output genre. Below is the 14 samples of data, just for you to get an impression of what im talking about. Sample HR RSP SC Activity Genre S1 Medium Low High Low Rock S2 High Low Medium High Rock S3 High High Medium Low Classic S4 High Medium Low Medium Classic S5 Medium Medium Low Low Classic S6 Medium Low High High Rock S7 Medium High Medium Low Classic S8 High Medium High Low Rock S9 High High Low Low Classic S10 Medium Medium Medium Low Classic S11 Medium Medium High High Rock S12 Low Medium Medium High Classic S13 Medium High Low Low Classic S14 High Low Medium High Rock My time of work regarding HMM is quite low, so my question to you is if I got the right angle on the assignment. I have three different states for each sensor: Low, Medium, High. Two observations/output symbols: Rock, Classic In my own opinion I see my start probabilities as the weightened factors for either a Low, Medium or High state in the Heart Rate. So the ideal solution for the AI is that it will learn these 14 sets of samples. And when a users sensor input is received, the AI will compare the combination of states for all four sensors, with the already memorized samples. If there exist a matching combination, the AI will choose the genre, and if not it will choose a genre according to the weightened transition probabilities, while simultaniously updating the transition probabilities with the new data. Is this a right approach to take, or am I missing something ? Is there another way to determine the output probability (read about Maximum likelihood estimation by EM, but dont understand the concept)? Best regards, Casper

  • Classification: Dealing with Abstain/Rejected Class

    - by abner.ayala
    I am asking for your input and/help on a classification problem. If anyone have any references that I can read to help me solve my problem even better. I have a classification problem of four discrete and very well separated classes. However my input is continuous and has a high frequency (50Hz), since its a real-time problem. The circles represent the clusters of the classes, the blue line the decision boundary and Class 5 equals the (neutral/resting do nothing class). This class is the rejected class. However the problem is that when I move from one class to the other I activate a lot of false positives in the transition movements, since the movement is clearly non-linear. For example, every time I move from class 5 (neutral class) to 1 I first see a lot of 3's before getting to the 1 class. Ideally, I will want my decision boundary to look like the one in the picture below where the rejected class is Class =5. Has a higher decision boundary than the others classes to avoid misclassification during transition. I am currently implementing my algorithm in Matlab using naive bayes, kNN, and SVMs optimized algorithms using Matlab. Question: What is the best/common way to handle abstain/rejected classes classes? Should I use (fuzzy logic, loss function, should I include resting cluster in the training)?

  • Emails sometimes get scrambled

    - by Alex
    Folks, I have a PHP-based based site (using the QCubed framework); as a part of the site, I have a daemon that's sending out several thousand emails a day (no i'm not a spammer, everything is opt-in :)). Emails are sent through a custom framework component; that component serves as an SMTP client. I'm using a paid SMTP gateway from DNSExit.com to get the emails actually delivered. Those emails are simple HTML-based emails; they really have just simple links inside. My issue is that these links sometimes (not consistently!) get scrambled during transition. Tags somehow get mixed up, and some links are non-functional in the email. The issue happens on a small percentage of all sent emails; it is not consistent (i.e. the same exact source message HTML may or may not cause the scrambling in transition). Have any of you seen this? Any thoughts on how to troubleshoot?

  • How to calculate the normal of points on a 3D cubic Bézier curve given normals for its start and end points?

    - by Robert
    I'm trying to render a "3D ribbon" using a single 3D cubic Bézier curve to describe it (the width of the ribbon is some constant). The first and last control points have a normal vector associated with them (which are always perpendicular to the tangents at those points, and describe the surface normal of the ribbon at those points), and I'm trying to smoothly interpolate the normal vector over the course of the curve. For example, given a curve which forms the letter 'C', with the first and last control points both having surface normals pointing upwards, the ribbon should start flat, parallel to the ground, slowly turn, and then end flat again, facing the same way as the first control point. To do this "smoothly", it would have to face outwards half-way through the curve. At the moment (for this case), I've only been able to get all the surfaces facing upwards (and not outwards in the middle), which creates an ugly transition in the middle. It's quite hard to explain, I've attached some images below of this example with what it currently looks like (all surfaces facing upwards, sharp flip in the middle) and what it should look like (smooth transition, surfaces slowly rotate round). Silver faces represent the front, black faces the back. Incorrect, what it currently looks like: Correct, what it should look like: All I really need is to be able to calculate this "hybrid normal vector" for any point on the 3D cubic bézier curve, and I can generate the polygons no problem, but I can't work out how to get them to smoothly rotate round as depicted. Completely stuck as to how to proceed!

  • Mootools Javascript can't push to array

    - by nona
    I have an array set with the heights of each hidden div, but when I use it, the div instantly jumps down, rather than slowly sliding as when there is a literal number. EDIT: testing seems to reveal that it's a problem with the push method, as content_height.push(item.getElement('.moreInfo').offsetHeight);alert(content_height[i]);gives undefined, but alert(item.getElement('.moreInfo').offsetHeight); gives the correct values Javascript: window.addEvent('domready', function(){ var content_height = [];i=0; $$( '.bio_accordion' ).each(function(item){ i++; content_height.push( item.getElement('.moreInfo').offsetHeight); var thisSlider = new Fx.Slide( item.getElement( '.moreInfo' ), { mode: 'horizontal' } ); thisSlider.hide(); item.getElement('.moreInfo').set('tween').tween('height', '0px'); var morph = new Fx.Morph(item.getElement( '.divToggle' )); var selected = 0; item.getElement( '.divToggle' ).addEvents({ 'mouseenter': function(){ if(!selected) this.morph('.div_highlight'); }, 'mouseleave': function(){ if(!selected) { this.morph('.divToggle'); } }, 'click': function(){ if (!selected){ if (this.getElement('.symbol').innerHTML == '+') this.getElement('.symbol').innerHTML = '-'; else this.getElement('.symbol').innerHTML = '+'; item.getElement('.moreInfo').set('tween', { duration: 1500, transition: Fx.Transitions.Bounce.easeOut }).tween('height', content_height[i]); //replacing this with '650' keeps it smooth selected = 1; thisSlider.slideIn(); } else{ if (this.getElement('.symbol').innerHTML == '+') this.getElement('.symbol').innerHTML = '-'; else this.getElement('.symbol').innerHTML = '+'; thisSlider.slideOut(); item.getElement('.moreInfo').set('tween', { duration: 1000, transition: Fx.Transitions.Bounce.easeOut }).tween('height', '0px'); selected = 0; } } }); } ); }); Why could this be? Thanks so much!

  • JQuery with css3 keydown keyCode = 37 and 39

    - by rayrule
    I have tested both ways. jquery animation and css3 transition, and css3 is a little bit faster. But i have a problem with the following code: $(document).keydown(function(e){ if (e.keyCode == 39) { var DocHeight = $(document).height(); $('.container').css("margin-top","-="+DocHeight) } }); if i hit twice on keyCode 39 (arrow to the right) than my transition is outer space. Does anyone has an solution for this thing? outer space maybe not the correct word. But the problem is. if i hit twice the arrow key i'll get the last request, in other words... animation is started, and another animation start from the position that i don't want. example: hit #1 margin-top is at 0px and goes to 1024px. but when i hit it twice the margin-top is at 23px, and it stops at 1047px. This is not what i want. It has to stop at 1024px. I hope so.

  • App is fast on 3GS but slow on 3G

    Hi all, I'm new to computer coding and have just finished coding an app and tested it on both 3G and 3GS. On 3GS, it worked as normal as on the simulator. However, when I tried to run it on 3G, the app becomes extremely slow. I'm not sure what's the reason and I hope someone could shed some light on me. Generally, my app has a couple of view controller classes, with one of them being the title page, one being the main page, one is setting, etc. I used a dissolve to transition from the title page to the main page. But even this simple transition shows un-smooth performance on a 3G! My other part of the app involves zooming in to some images by scaling up the images, switching images by push or dissolve upon receiving touch events, saving photos into photo library and storing and retrieving some photos in a folder and some data in a SQlite database, each showing un-smooth actions. Compared with some heavy graphic or heavy maths app, I think mine is pretty simple. I totally have no clue why the app would behave so slow and un-smooth that it is barely useful on a 3G. Any help/ direction would be much appreciated. Thanks for helping out.

  • Scroll view to bottom while keyboard is hiding

    - by Manu
    Hi! I'm using a scroll view to move my view and show certain text fields (that otherwise would be hidden) when the keyboard shows. I basically resize the scroll view to make room for the keyboard, and then scroll up the view smoothly with "scrollRectToVisible", which works perfectly. After that, I can scroll and edit the rest of the text fields without lowering the keyboard, which is what I intend. The problem comes when I want to hide the keyboard again. I have been able to lower the keyboard and scroll down the view to its original position without a problem, but I have been unable to make that transition smooth. At the moment I use the following: - (void)keyboardWillHide: (NSNotification *)notif { CGRect topRect = CGRectMake(0, 0, 1, 1); [scrollview scrollRectToVisible:topRect animated:YES]; scrollview.frame = CGRectMake(0, 0, scrollviewWidth, scrollviewHeight); } I create a CGRect at the top, which I then move into view with "scrollRectToVisible". That works fine and commences the scrolling right when the keyboard is hiding (I use "keyboardWillHide" and not "keyboardDidHide" because the scroll view frame is still missing its lower part). The problem comes when I resize the scroll view frame back to its original dimensions (which I need to do), because then the scrolling is interrupted and the view drops to the bottom suddenly (as there is nothing else to scroll). This causes a glitch, which is why I cannot complete the transition smoothly. Any ideas on how could I lower the keyboard while scrolling the view down smoothly? Should I be scrolling up a bigger view, instead of resizing it? That way I would not have to restore the scroll view frame dimensions when lowering the keyboard, or would I? Thanks very much in advance!

  • Navigation Controller not Pushing/Popping View Controllers

    - by senfo
    I'm working on a view-based iPhone app that has the following flow: search - (list | map) - details To accomplish the transitions between views, I have a UINavigationController, with the search view controller being the root. After a user performs a search, I transition to a view with a segmented control, which acts as a tab to switch between the list and map functionality (per a suggestion from a related question I had). This view contains a UIViewController, which allows me to switch between the list/map view when a user taps the segmented control. I'm fine up until this point. As you can see from the above mentioned flow, I would like to provide the ability to transition into a details view. Each row of my table in the list view contains a details disclosure button for allowing the user to drill down into a details view. The problem is, when I try to push the details view onto the navigation stack, nothing happens. Below is the delegate method (from my list view controller) to handle the details disclosure button being tapped. I've set up break points, so I know the code is running. The navigation controller simply doesn't want to push the detailsController onto the stack (my guess is that I don't have a pointer to the correct UINavigationController). - (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath { if (detailController == nil) { detailController = [[DetailsViewController alloc] init]; } [self.navigationController pushViewController:detailController animated:YES]; } Assuming I was probably missing a pointer to the navigation controller, I exposed a UINavigation property on my list and map views (navigationController is readonly) and initialized them with a pointer to the navigation controller from my SwitchViewController (the view responsible for switching between list/map views when a user changes the value of the segmented control). Unfortunately, this did not solve the problem. Am I on the right track? If so, how do I see to it that my view has a pointer to the correct navigation controller? Should I add a delegate, which allows me to call a function in the SwitchViewController that transitions into the details view (this seems messy)?

  • Why does my JQuery Image swap not work in firefox or chrome, but fine in IE?

    - by Cognize
    Hi, Relatively new to JQuery. I've got some code that does a banner swap with a fade in fade out transition. The images swap as expected in IE8, chrome, and firefox. However, the actual fade, the smooth transition between images only works in IE. Can anyone point me in the right direction for a fix? Javascript: function swapImages() { var $active = $('#transitionImagePlaceHolder .active'); var $next = ($('#transitionImagePlaceHolder .active').next().length > 0) ? $('#transitionImagePlaceHolder .active').next() : $('#transitionImagePlaceHolder img:first'); $active.fadeOut( 'slow', function () { $next.fadeIn('slow').addClass('active'); $active.removeClass('active'); }); } $(document).ready(function () { setInterval('swapImages()', 5000); }); CSS: #transitionImagePlaceHolder { } #transitionImagePlaceHolder { position:relative; left: 26px; } #transitionImagePlaceHolder img { display:none; position:absolute; top:4; left:10; } HTML: <div id="transitionImagePlaceHolder"> <img class="active" src="Images/TransitionImages/Trans_Img_1.jpg" /> <img src="Images/TransitionImages/Trans_Img_2.jpg" /> <img src="Images/TransitionImages/Trans_Img_3.jpg" /> </div>

  • Improving the efficiency of multiple concurrent Core Animation animations

    - by Alex
    I have a view in my app that is very similar to the month view in the built-in Calendar app. There's a subview that holds the individual cells (a custom UIView subclass that draws text into its layer), and when the user navigates to the next "month", I create the new cells and slide the view to show them. When the animation stops, I remove the old, hidden cells and set things up so it's ready to go for the next animation. This all works nicely. However, I'd like to animate the cells' text color, as in the Calendar app, so that the outgoing ones transition to a lighter color and the incoming ones transition to a darker color. The problems is that I can have as many as 70 cells, so doing individual animations is very slow -- between 5-10 fps on my iPhone 3GS. I'm trying to find a less computationally intense way of doing this. My reading of the Shark results is that the majority of the time is spent redrawing the text for each frame for each frame. This makes sense, since text rendering is hardly the cheapest operation. I've considered creating a second view -- one holding the "outgoing" state and one holding the "incoming" state and using a single opacity animation to gradually reveal the updated cells while both are sliding. I'm concerned that instead of having 70 cells, I'll have 140, which seems like a lot of views. So, is that too many views or would there be a better way of doing this?

  • Game design flaw, need help investigating

    - by Snake
    I am not sure if I will be able to get help here but I would give it a shot. The problem is I dont know where the problem is. I have a cards game, in which when you "human" play by dragging a card, then at the end of card being dragged, a handler using postExecute is called with delay of 0.5 sec to start the next player in turn (which is a bot) The bot chooses the color and plays it and at the end of the animation (the card moving to the middle) a handler is started for the next bot and so on. Once the play reaches again to the human player, it waits for his touchs to drag the crad and start the cycle again. The problem that in production, sometimes I am getting errors. The error is resulting in somehow messing up the sequence which ends up with players having more cards than others. After investigation, I found that the transition from human to bot is the problem. Somehow, the transition is happening twice (meaning handler calling post execute twice and the bot is playing twice and everything is messed up). Its been mutliple months and I can't reproduce it (to fix it) and I cna't figure out why this is happeneing? ANY IDEA how I can go after it? How can I get more info about or how can I solve something like that? any pointer would help me

  • Recomendations for Creating a Picture Slide Show with Super-Smooth Transitions (For Live Presentaito

    - by Nick
    Hi everyone, I'm doing a theatrical performance, and I need a program that can read images from a folder and display them full screen on one of the computer's VGA outputs, in a predetermined order. All it needs to do is start with the first image, and when a key is pressed (space bar, right arrow), smoothly cross-fade to the next image. Sounds just like power-point right? The only reason why I can use power-point/open-office is because the "fade smoothly" transition isn't smooth enough, or configurable enough. It tends to be fast and choppy, where I would like to see a perfectly smooth fade over, say, 30 seconds. So the question is what is the best (cheap and fast) way to accomplish this? Is there a program that already does this well (for cheap or free)? OR should I try to hack at open-office's transition code? Or would it be easier to create this from scratch? Are there frameworks that might make it easier? I have web programming experience (php), but not desktop or real-time rendering. Any suggestions are appreciated!

  • Pros/Cons of switching from Exchange to GMail

    - by Brent
    We are a medium-large non-profit company, with around 1000 staff and volunteers, and have been using MS Exchange (currently 2003) for our mail system for years. I recently attended a Google conference where they were positing that "Cloud computing is the way of the future", and encouraging us to switch from doing our own email with Exchange, to using GMail and Google Apps for everything. Additionally, one of our departments has been pushing from inside to do this transition within their own department, if not throughout the entire organization. I can definitely see some benefits - such as: Archive space - we never seem to have the space our users want, and of course, the more we get, the more we have to back up OS Agnostic - Exchange is definitely built for windows, and with mac and linux users on the rise, these users increasingly demand better tools / support. Google offers this. Better archiving - potential of e-discovery, that doesn't exist in a practical way with our current setup. Switching would relieve us of a fair bit of server administration, give more options to our end users, and free up the server resources we are now using for Exchange. Our IT department wants to be perceived as providing up-to-date solutions to technical problems, and this change would definitely provide such an image. Google's infrastructure is obviously much more robust than ours, and they employ some of the world's best security and network experts. However, there are also some serious drawbacks: We would be essentially outsourcing one of our mission-critical systems to a 3rd party The switch would inevitably involve Google Apps and perhaps more as well. That means we would have a-lot more at the mercy of a single (potentially weak) password. (is there a way to make this more secure using a password plus physical key of some sort??) Our data would not remain under our roof - or even in our country (Canada). This obviously has plusses on the Disaster Recovery side, but I think there are potential negatives on the legal side. I can't imagine that somebody as large as Google would be as responsive as we would want with regard to non-critical issues such as tracing missing emails, etc. (not sure how much access we would have to basic mail logs - for instance) Can anyone help me evaluate this decision? What issues am I overlooking? What experiences have you had with this transition (or the opposite - gmail to Exchange) Can you add to the points I have already outlined?
