  • How can I undo this key mapping?

    - by user273872
    First of all sorry my punctuation will be bad. its hard to type when keys are not doing what you expect. Eg it keeps scaring the **** out of me by taking a screen shot when I push the up arrow lolol So anyways, I broke a key on my keyboard and used xkeycaps to remap it to an unused key which worked. But then I realized it screwed up other keys... I think this is the program I used http://www.jwz.org/xkeycaps/man.html And then after doing the modifications I found out how to save them from the second answer in this question How to Map my enter key to a different key down where it says this "When you are happy with your current keymap and want to use it in future X-sessions, run the following command to save it: xmodmap -pke ~/.Xmodmap"

  • How to window.open with a toolbar in Google Chrome?

    - by brahn
    The following javascript opens a pop-up in Firefox, Safari, IE, and Google Chrome: window.open("http://google.com", "foo", "toolbar=yes,location=yes,menubar=yes") However, in Google Chrome the toolbar (with the usual forward and back buttons, etc.) does not appear on the popped-up window. (Tested on both Windows and Mac.) How can I fix this? I would like the user to be able to navigate forward and back using the tools with which they are most familiar. Thanks!

  • PHP save a page then redirect to previous page(ajax)

    - by Shiro
    Dear all, I would like to ask for how to redirect to previous page (ajax paging). Example, Let's say currently I am in page 5, then I click on one record, after I edit it, I would like to go back to that page 5 not page 1. The problem is my paging is using ajax, http://domain/photo/#5 I try to use $_SERVER[http_referer], but I only get http://domain/photo , I not able to get # and the value. What is the best way to redirect back to the previous paging. My last choice is using $_SESSION. Hope I can get better answer here. Thx.

  • Retrieve data from an ASP.Net application using ADO.Net 2.0 connected model

    - by nikolaosk
    I have been teaching Entity Framework,LINQ to SQL,LINQ to objects,LINQ to XML for some time now. I am huge fan of LINQ to Entities and I am using Entity Framework as my main data access technology. Entity framework is in the second version right now and I can accomplish most of the things I need. I am sure the guys in the ADO.Net team will implement many more features in the future. I am a strong believer that you cannot really understand the benefits of LINQ to SQL or LINQ to Entities unless you...(read more)

  • Learning rails and AJAX. How do I load a div via ajax and then toggle hiding/showing it?

    - by Kevin L.
    I'm doing my first Ruby on Rails project. I am working on a project where the user can add a new message. Then they can add updates to this message like a thread. I've got it all written and now I'm going back and applying some AJAX. I want to show just the main message when the page first loads. Then when I click a link I want an AJAX event to fire that populates a div with all the updates to the message. Then I want this same link to toggle hiding and showing the div. I've made a submit button to fire the ajax and get back the updates using form_remote_tag. I've also created a separate link to toggle the hiding using $(div_id).toggle();. But now I'm stuck on how to combine these two things into one all purpose link. Thanks.

  • Convert user title (text) to URL, what instead spaces, #, & and other characters?

    - by Thomas
    I have some form on the website where users can add new pages. I must generate SEO friendly URLs and make this urls unique. What characters can I display in url, I know that spaces I should convert to undescore: " "-"_" and before it - underscores to something else, for example: ""-"()" It is easy make title from url back. But what in my specific title can be all characters from keyboard, even : @#%:"{/\';. Are some contraindications to don't use this characters in URL? Important for me is: -easy generate url and title from url back (without queries to database) -each title are unique, so url must be too -SEO friendly URLs

  • Avoiding Nested Blocks

    - by Helium3
    If there is a view controller that wants to execute a number of block based tasks one at a time, how can the control be given back to the view controller after a completion block has executed. Lets say ViewControllerOne wants to execute a number of tasks, each relying on the result of the previous one, how would this control be given back to the viewcontroller after each completion block has been executed? I started thinking about this and I was heading towards a deeply nested block pattern that will surely only cause confusion to whoever else reads or tests it. A task executes and the completion block returns the result or error which is needed by the next task, which has its own completion task, that the next task relies on and so forth. How can the control be managed in one place, the viewcontroller? Would the completion block just call the next function that handles the next task, using a pointer to the view controller?

  • Why do exclusively outsourcing projects as a company?

    - by user19833
    A prospective employer told me they took a company level decision to only do outsourcing projects. I do not understand why did they take such a decision and the guy I talked to did not elaborate. He further said only that "their intention is to build software components". Since they are growing quite fast and reached around 300 employees, shouldn't they be at least open to the possibility of having a project of their own, maybe? All other companies I've had contact with were at least open to have one in the future.. I talked to a few of their employees and some are working in parallel on more than 2 outsourced projects (dividing time something like 4 + 4 hours / day). It seemed like a lot of projects with a period of a few months, maybe half an year come and go... Why would a company choose to provide only outsourcing services like that? How does it work to keep hundreds of people on outsourced projects with a seemingly high project turnover rate?

  • Should I work for free while applying for a job?

    - by Jevgeni Bogatyrjov
    An employer usually asks a candidate to do a small project at home ("homework") as a part of applying for a job. Last time I applied for a job (as a web developer), there were aproximately 10 applicants who were all given different tasks. Despite the fact that there was only one vacancy, the company used the work of all of the candidates in one of its projects. Actually, it is quite reasonable for a company to create these "vacancies" just to make people work for free - I estimate, that aproximately 2 weeks of programmer's work was saved with all of the job applications that company had on one vacancy. Is this a common practice and how can you protect yourself from working for free in the future? Have you seen this during your career?

  • Can my tortoise vs. hare race be improved?

    - by FredOverflow
    Here is my code for detecting cycles in a linked list: do { hare = hare.next(); if (hare == back) return; hare = hare.next(); if (hare == back) return; tortoise = tortoise.next(); } while (tortoise != hare); throw new AssertionError("cyclic linkage"); Is there a way to get rid of the code duplication inside the loop? Am I right in assuming that I don't need a check after making the tortoise take a step forward? As I see it, the tortoise can never reach the end of the list before the hare (contrary to the fable). Any other ways to simplify/beautify this code?

  • Should I force users to update an application?

    - by Brian Green
    I'm writing an application for a medium sized company that will be used by about 90% of our employees and our clients. In planning for the future we decided to add functionality that will verify that the version of the program that is running is a version that we still support. Currently the application will forcequit if the version is not among our supported versions. Here is my concern. Hypothetically, in version 2.0.0.1 method "A" crashes and burns in glorious fashion and method "B" works just fine. We release 2.0.0.2 to fix method A and deprecate version 0.1. Now if someone is running 0.1 to use method B they will be forced to update to fix something that isn't an issue for them right now. My question is, will the time saved not troubleshooting old, unsupported versions outweigh the cost in usability?

  • Upgrade MySQL to 5.5 on Lucid, upgrade server to Precise or switch to Percona?

    - by xref
    Looking into upgrading mysql on our development server to which is running 10.04 so is stuck at MySQL 5.1, as it appears there is no apt-get support for upgrading to 5.5 except by certain 3rd party PPAs. So I'm looking for which route to take and what other people have done: a) Follow a couple year old guide to manually install MySQL 5.5 and then invest ongoing time into manually downloading and installing security updates every month or two? b) Upgrade 10.04 to 12.04, and from other peoples experience I work with spend several days working out the kinks of that large upgrade, then I'll have access to mysql 5.5 and easy apt-get installation of future security updates? c) Switch from MySQL to Percona Server 5.5 and get all the benefits of that version of mysql, plus easy apt-get updates with their PPA? d) Something else?

  • Facebook page linking to external site sign-up process, capture permission to write to wall in process?

    - by steve
    Hi all, Have had a good hunt through the archive but can't find anyone trying to do this... hope someone familiar with the facebook API can confirm if it's possible? Basically I have a client who wants to replicate their membership sign up process in a tab on their facebook page. The form would still submit to their own website to process, we'd just be replicating the form fields. As an additional requirement they want to capture peoples facebook user ID and get permission to post back to a users wall at the same time... The idea being that once the user is a member we can post back to their wall so their friends see that they've signed up... Basically after a sanity check that: 1) these things are possible to do; 2) the best method to build the form in a FB page - I'm guessing using JS to create all fields & ajax to submit to the external site? Thanks Steve

  • Exposing a "dumbed-down", read-only instance of a Model in GAE

    - by Blixt
    Does anyone know a clever way, in Google App Engine, to return a wrapped Model instance that only exposes a few of the original properties, and does not allow saving the instance back to the datastore? I'm not looking for ways of actually enforcing these rules, obviously it'll still be possible to change the instance by digging through its __dict__ etc. I just want a way to avoid accidental exposure/changing of data. My initial thought was to do this (I want to do this for a public version of a User model): class ReadOnlyUser(db.Model): display_name = db.StringProperty() @classmethod def kind(cls): return 'User' def put(self): raise SomeError() Unfortunately, GAE maps the kind to a class early on, so if I do ReadOnlyUser.get_by_id(1) I will actually get a User instance back, not a ReadOnlyUser instance.

  • May I give a single class multiple responsibilities if only one will ever be reusable?

    - by lnluis
    To the extent that I understand the Single Responsibility Principle, a SINGLE class must only have one responsibility. We use this so that we can reuse other functionalities in other classes and not affect the whole class. My question is: what if the entity has only one purpose that really interacts with the system, and that purpose won't change? Do you have to separate the implementations of your methods into another class and just instantiate those from your entity class? Or to put it another way... Is it ok to break the SRP if you know those functions will not be reusable in the future? Or is it better to assume that we do not know if the functionalities of these methods will be reusable or not, and so just abstract them to other classes?

  • Webkit browser jQuery transformations/transitions not working with jSplitSlider

    - by user3689793
    I am helping to build a site and i'm having an issue with the functionality of an add-in called jsplitslider when running it in chrome. Right now, when I navigate between the slides, the div's get stuck on top of each other and never clear the webkit transformations/animations: <div class="sl-content-slice" style="transition: all 800ms ease-in-out; -webkit-transition: all 800ms ease-in-out;"> I think the problem is due to timing of the functions, but I can't seem to figure out where I would need to add a setTimeout(). I only think this because I exhausted a lot of the other options like display: inline-block, notransitions css, etc. I'm desperate to figure out how to make this work in chrome. It works in FF and IE(surprisingly enough). I'm not great at webcoding, so any help will be appreciated! The code on the site isn't minimized. Here is the jQuery where I think the problem lies: var cssStyle = config.orientation === 'horizontal' ? { marginTop : -this.size.height / 2 } : { marginLeft : -this.size.width / 2 }, // default slide's slices style resetStyle = { 'transform' : 'translate(0%,0%) rotate(0deg) scale(1)', opacity : 1 }, // slice1 style slice1Style = config.orientation === 'horizontal' ? { 'transform' : 'translateY(-' + this.options.translateFactor + '%) rotate(' + config.slice1angle + 'deg) scale(' + config.slice1scale + ')' } : { 'transform' : 'translateX(-' + this.options.translateFactor + '%) rotate(' + config.slice1angle + 'deg) scale(' + config.slice1scale + ')' }, // slice2 style slice2Style = config.orientation === 'horizontal' ? { 'transform' : 'translateY(' + this.options.translateFactor + '%) rotate(' + config.slice2angle + 'deg) scale(' + config.slice2scale + ')' } : { 'transform' : 'translateX(' + this.options.translateFactor + '%) rotate(' + config.slice2angle + 'deg) scale(' + config.slice2scale + ')' }; if( this.options.optOpacity ) { slice1Style.opacity = 0; slice2Style.opacity = 0; } // we are adding the classes sl-trans-elems and sl-trans-back-elems to the slide that is either coming "next" // or going "prev" according to the direction. // the idea is to make it more interesting by giving some animations to the respective slide's elements //( dir === 'next' ) ? $nextSlide.addClass( 'sl-trans-elems' ) : $currentSlide.addClass( 'sl-trans-back-elems' ); $currentSlide.removeClass( 'sl-trans-elems' ); var transitionProp = { 'transition' : 'all ' + this.options.speed + 'ms ease-in-out' }; // add the 2 slices and animate them $movingSlide.css( 'z-index', this.slidesCount ) .find( 'div.sl-content-wrapper' ) .wrap( $( '<div class="sl-content-slice" />' ).css( transitionProp ) ) .parent() .cond( dir === 'prev', function() { var slice = this; this.css( slice1Style ); setTimeout( function() { slice.css( resetStyle ); }, 150 ); }, function() { var slice = this; setTimeout( function() { slice.css( slice1Style ); }, 150 ); } ) .clone() .appendTo( $movingSlide ) .cond( dir === 'prev', function() { var slice = this; this.css( slice2Style ); setTimeout( function() { $currentSlide.addClass( 'sl-trans-back-elems' ); if( self.support ) { slice.css( resetStyle ).on( self.transEndEventName, function() { self._onEndNavigate( slice, $currentSlide, dir ); } ); } else { self._onEndNavigate( slice, $currentSlide, dir ); } }, 150 ); }, function() { var slice = this; setTimeout( function() { $nextSlide.addClass( 'sl-trans-elems' ); if( self.support ) { slice.css( slice2Style ).on( self.transEndEventName, function() { self._onEndNavigate( slice, $currentSlide, dir ); } ); } else { self._onEndNavigate( slice, $currentSlide, dir ); } }, 150 ); } ) .find( 'div.sl-content-wrapper' ) .css( cssStyle ); $nextSlide.show(); }, _validateValues : function( config ) { // OK, so we are restricting the angles and scale values here. // This is to avoid the slices wrong sides to be shown. // you can adjust these values as you wish but make sure you also ajust the // paddings of the slides and also the options.translateFactor value and scale data attrs if( config.slice1angle > this.options.maxAngle || config.slice1angle < -this.options.maxAngle ) { config.slice1angle = this.options.maxAngle; } if( config.slice2angle > this.options.maxAngle || config.slice2angle < -this.options.maxAngle ) { config.slice2angle = this.options.maxAngle; } if( config.slice1scale > this.options.maxScale || config.slice1scale <= 0 ) { config.slice1scale = this.options.maxScale; } if( config.slice2scale > this.options.maxScale || config.slice2scale <= 0 ) { config.slice2scale = this.options.maxScale; } if( config.orientation !== 'vertical' && config.orientation !== 'horizontal' ) { config.orientation = 'horizontal' } }, _onEndNavigate : function( $slice, $oldSlide, dir ) { // reset previous slide's style after next slide is shown var $slide = $slice.parent(), removeClasses = 'sl-trans-elems sl-trans-back-elems'; // remove second slide's slice $slice.remove(); // unwrap.. $slide.css( 'z-index', 10 ) .find( 'div.sl-content-wrapper' ) .unwrap(); // hide previous current slide $oldSlide.hide().removeClass( removeClasses ); $slide.removeClass( removeClasses ); // now we can navigate again.. this.isAnimating = false; this.options.onAfterChange( $slide, this.current ); }, Sorry if I missed any conventions when posting, this is my first S.O. post. Thanks in advance for any help.

  • How do I avoid the complexity concerns of frameworks while keeping my team marketable?

    - by Desolate Planet
    When deciding upon how to design a software project with my colleagues, most suggestions tend to be for using specific frameworks "because it's popular in the job market" or "that's the framework that gets recruiters on the phone," and never what I'm looking for which is, "because it's a good fit for the project as it makes the system more adaptive to future changes and makes life easier for developers." I didn't start looking at projects in this way until I started reading up on domain-driven design. I've found that the actual domain is hidden deep under the frameworks used and it's hard to learn the business processes that have been implemented by the software product. Is there a way to marry the two competing goals: getting exposure as a development team while still being able to avoid complexity? Are frameworks that compromise, or are there other solutions out there?

  • Interviewing consultants

    - by SkyOrg
    I've interviewed a number of candidates for salaried positions. I was recently informed that we are hiring a consultant for a few months to help us develop a native iPhone application. We are a .NET shop and none of us have any experience with iPhone development. I've also heard rumors that we are planning to hire more consultants in the future to help develop on other various platforms. How should I interview these consultants, considering that I have no experience with this type of development? Without regards to platform specific questions, what are the things I need to keep in mind when interviewing consultants? Normally when I interview candidates, I'll ask questions that I know the answer to. I would never ask a candidate something that I don't know how to answer. Since this is a different situation, what do I need to ask in order to make sure they are subject matter experts in their respective fields? Is it appropriate to ask specific questions that we'll need to eventually solve during the interview?

How we can solve this problem. When every user clicks to enter page A, he should be able to see the page A. Anyone has the solution for my problem.

  • What can cause forms authentication to forget you are logged in?

    - by metanaito
    I have an asp.net web site that uses forms authentication. When users check the "remember me" it will remember the user if they close the browser and come back. I have the timeout set for a day or so. Recently I've noticed that I can be browsing the site and suddenly it forgets I'm logged in. It does not happen after 20 minutes as I can be actively browsing. My question is, what can cause this to happen? If the server recycles the app or app pool will the login be lost? On my local I can restart my machine and when I come back I'm still logged in.
