  • Should I try to write simple key-value storage by myself?

    - by shabunc
    I need a key-value storage in a simplest form we can think of. Keys should be some fixed-length strings, values should be some texts. This key-value storage should have an HTTP-backed API. That's basically it. As you can see, there is no big difference between such storage and some web application with some upload functionality. The thing is - it'll take few hours (including tests and coffee drinking) to write something like this. "Something like this" will be fully under my control and can be tuned on demand. Should I, in this specific case, not try to reinvent bicycles? Is it better to use some of existing NoSQL solutions. If yes, which one exactly? If, say, I'd needed something SQL-like, I won't ask and won't try to write something by myself. But with NoSQL I just don't know what is adequate and what is not.

    - by Dokkat
    I am an experienced programmer but completely new to the market. Someone wants me to do a project for them, but I do not know how much it is worth. What are general guidelines/advices for finding what a project is worth on the market? If I can ask here about this particular one, it is a HTML5 site with a login/register form and a video player that has to play a lecture video and powerpoint slides synchronized. They'll give me the video, the audio the powerpoints. I should also do some editting on the video before.

  • Framework to implement an in game gui editor

    - by momboco
    I need to do an in game gui editor. The game engine has his own widgets elements and I don't want a gui library that substitute it.

Positioning Resize Alignment between some elements Multiselection Relationship between children and parents Add guides Magnet to place elements quickly Use of layers Undo / Redo ... I'm searching a framework or something like, with these functionalities implemented. And a form of append my own engine to make use of it. It would be ideally a mixing between a tool like Photoshop and libRocket ( engine rendering independent ).

  • 14.04_x64 / Nvidia GT 240 , HUGE font notificaton at greeter and in naulitus after log-in

    - by mrlamud
    I've been using 12.04 for a long time - excellent version indeed, I decided to try 14.04 today. Installing without any problems. My VGA is Nvidia GT240 (legacy one), Nouveau display driver is fine, font display is normal. Then, I decided to install Nvidia legacy binary driver 304.117 updates (proprietary) instead of default Nouveau display driver. Problems come after rebooting At Greeter a notification "Wired connection 1 -Connected" pop up but with a HUGE font. After log-in HUGE FONT symptom still remains at some parts - for example, Calendar, Desktop shortcut and Files explorer. within few seconds, 10 to 15 may be, there is a screen blink but HUGE font still remains. I have to log out then log in again to have normal font in all parts of system. Changing driver, even an update one form ppa:xorg-edgersnot doesn't solve the problem. Any advices or solutions will be appreciated.

  • What is best way to create a cross fade effect?

    - by Starx
    While creating an Image Slider, cross-fade is one of most popular effects so far. Various slider on the internet use various techniques to create such effect. Major technique I have found so far are two: Some use a overlay and underlay div and fade in and out each others visibility. While others, create a div of exact size of the slider on the slider-initialization and play with its z-index property and then fade each other consequently. Disregarding them, what is a proper way or much better way to create a cross fade effect. P.S: I would love to read answer in form of algorithm.

An example is prairie identity server (openID). I need something similar but more customizable.

  • How to give life to my idea which belong to my company?

    - by pmod
    I wonder, what options do I have in the following situation. In the course of the several projects I realised the need in some auxilary software product (related to testing of the main products). I applied a creative approach to the matter and implemented a system which I think has a potential and looking promising (maybe not on the market but at least among some interested supporters). I have even more ideas related to this system and continue developing at my free and work time. It has become a work and hobby at the same time. Unfortunately, this work basically has nothing in common with the company's business and there is no way this will be organized in a form of standard development process and be presented to costumers as a product. What can you suggest in this situation? How to avoid breaching of contract? Have you had something similar in your career? What if my intention is to develop it as an open source project?

  • Is the php method md5() secure? Can it be used for passwords? [migrated]

    - by awiebe
    So executing a php script causes the form values to be sent to the server, and then they are processed. If you want to store a password in your db than you want it to be a cryptographic hash(so your client side is secure, can you generate an md5 using php securely( without submitting the user:password pair in the clear), or is there an alternative standard method of doing this, without having the unecrypted pasword leaving the clients machine? Sorry if this is a stupid question I'm kind of new at this. I think this can be done somehow using https, and on that note if a site's login page does not use https, does that mean that while the databse storage is secure, the transportation is not?

  • Would I benefit changing from PHP to Node.js (in context)

    - by danneth
    The situation: We are about to roll out what is essentially a logging service. As we are rather PHP heavy, the current implementation use it. We will have about 200 computers (most on the same network) that will each send, via HTTP POST, around 5000 requests/day. With each request containing about 300 bytes of data. The receiving end is hosted at Amazon and is a very simple PHP form with some simple validation that puts everything in a database. Now, I've recently been introduced to Node.js and I'm curious as to if it would be a good fit for the backend here. Granted I could easily build something to test this. But since I haven't fully grasped the async-methology I would really like someone with experience to explain it to me.

  • Is it possible to force a tab/window to take focus without an alert()? [migrated]

    - by Chris Brandt
    I've been working to solve some form / session timeout issues on our site. I'd like to get the users attention BEFORE this happens so that they don't lose data that they've entered into long forms. I'm using jquery's .get to confirm with my server when the users session is set to timeout, and warn them 5 minutes before then. I've found that if I pop an alert(), it will bring the focus back to that tab / page -- but this seems 'heavy handed'. Is there a better way to do this?

  • Keeping application backend and UI synchronised

    - by Deanna
    Hi all. I have an app that works with a list of objects so has one central keyed list. The main window has a tree containing these object with some information, which is easy enough to populate as a one off event after loading. Now, the complicated part, any part of the application can add, remove, and more importantly change the details of those objects at any time (all in the same process) and I'd like the tree to update to suit. I have a few options including passing events back down from the object to the list to the form which seems to be the most flexible way. I can also do it lazily and repopulate the tree each time or periodically (very hackish). Does anyone have any better thoughts on how to structure this? This is being done in C# 2.0 but the concepts apply to any environment. Thanks

  • How should I design my website to allow posterity to edit?

    - by SSumner
    I'm building a website for a student organization I am involved in at my college. Most of the site will be static - i.e. won't change from year-to-year, but certain pieces will. I am high-tech, but most of the others aren't, and I am graduating in the spring. So how should I go about building the website so as to allow those that take over in subsequent years to edit information? Examples: Events: I already plan on using a Google calendar for this Officers: There will be profiles/pictures for all the officers on the web page Connections: Partnerships with other organizations that we have currently, but may not in future, or may add more in future Should I use some form of CMS (Content Management System)? If so, how restrictive are they (e.g. Drupal) to what you can build and then how easy is it to edit. What other ways could I make a very nice-looking website but allow certain pieces to be edited later?

  • input type="email"

    - by Charles
    I have a form where I ask for email addresses. Usually I'd use <input type="email" ...> but I want to allow a user to type foo rather than [email protected] in the (likely) case that they are using an @mycompany.com email address. Is there a way to get around the validation (if format matches this regex, accept; otherwise, validate normally), or should I just use <input type="text" ...> and ignore the semantics and so forth?

  • "Mega Menus" for SEO [duplicate]

    - by Thought Space Designs
    This question already has an answer here: How do I handle having to many links on a webpage because of my menu 4 answers I'm using the term "Mega Menus" loosely here. I'm redesigning my WordPress site (it's going to be responsive), and as part of the redesign, I was debating incorporating some sort of descriptive menu setup. For example, normal navigation drop down menus come in the form of unordered lists of links like so: <nav> <ul> <li> <a href="#">Link1</a> </li> <li> <a href="#">Link2</a> </li> <li> <a href="#">Link3</a> <ul> <li> <a href="#">Sub Link1</a> </li> <li> <a href="#">Sub Link2</a> </li> <li> <a href="#">Sub Link3</a> </li> </ul> </li> <li> <a href="#">Link4</a> </li> </ul> </nav> What I'm looking to do is build my drop down menus with more information than your standard menu. For example, I have a top level link named "Team", and under that link, I want to make a large drop down that contains head shots, headers (in the form of styled p tags) and brief (<100 words) descriptions of each team member (only 2 currently). I want to accompany this with a "Read More" link that takes you to their actual team page. This is just one example, of course, and the other top level links would also have descriptive drop downs in the same fashion. On mobile, I was planning on hiding the "mega menu", and delivering a standard unordered list of links. Here's what I was thinking for overall structure and syntax: <nav> <ul> <li> <a href="#">Home</a> </li> <li> <a href="#">About</a> </li> <li> <a href="#">Team</a> <ul> <!-- DESKTOP --> <li class="mega-menu row"> <a class="col-sm-6" href="#"> <div class="row"> <div class="col-sm-4"> <img src="#" alt="Team Member 1" /> </div> <div class="col-sm-8"> <p class="header">Team Member 1</p> <p>Short description goes here.</p> </div> </div> </a> <a class="col-sm-6" href="#"> <!-- OTHER TEAM MEMBER INFO --> </a> </li> <!-- END DESKTOP --> <!-- MOBILE --> <li> <a href="#">Team Member 1</a> </li> <li> <a href="#">Team Member 2</a> </li> <!-- END MOBILE --> </ul> </li> <li> <a href="#">Contact</a> </li> </ul> </nav> Can anybody think of any potential SEO ramifications of doing this? I'm not going to be loading these menus full of links, so it shouldn't hurt page rank, but what are the effects of having a good bit of text and maybe even forms within nav elements? Is there such a thing as overloading nav with HTML? EDIT: Here's an example of what the menu would look like rendered on desktop. I'm currently hovering the "Team" menu, but you can't see because my mouse went away when I took the screenshot. EDIT 2: This question is not a duplicate. I'm not going to have "too many" links in my menus. I'm wondering how having images and text inside of header navigation will affect my menus. Also, I don't just want "yes, this is bad" answers. Please cite your sources and be specific with reasoning.

  • XNA + Windows Forms: How make them work together without making the trick of the custom GraphicsDeviceControl?

    - by Renann
    What I've found is a solution where you have to code a custom GraphicsDeviceControl to put inside the form (the well known tutorial from the APPHub), but that's not what I'm searching for. I would like to say that before start to right my question here, I "googled" a lot and I saw some questions here, but I couldn't find what I'm looking for. I would like to have the Draw/Update loops completly managed by XNAFrameWork (with XNA project and so), and not by a custom component. I hope you understand what I asked. Thanks in advance. Edit What's the most important thing for me and wasn't shown in the tutorial of APPHub is: where I have to put the input handling? That's one the problems that wasn't covered by the tutorial.

  • Good way to extract strings to resource

    - by Bart Friederichs
    I am using Visual Studio 2010 and we just decided to get started on localization of our code. We want to use the per-form resource file in combination with a separate resource file for static strings, called strings.resx. I was wondering if there is a good way to extra static strings (we already have quite some code we need to translate) to the strings.resx file? I have tried this plugin: Resource Refactoring 2010, but it doesn't work completely. It creates the correct new resource, but the strings aren't refactored in the code. Also, the tool seems to be abandoned by its developer. Is there a good plugin that can do this?

  • PHPmyedit: custom URL for 'ADD' button [on hold]

    - by user2952715
    I'm currently working with phpmyedit and I need to access to the 'Add' (new record) function using a URL. As this script (phpmyedit) is dinamically generated, when I press the 'Add' button, I get the form to fill but the URL has no changes. How can I create some custom URL for the ADD button, that allows me to access externally and also pass parameters through the URL? Here is how PHPmyedit set up the navigation buttons by default: http://opensource.platon.sk/projects/doc.php/phpMyEdit/html/configuration.navigation.html Any help will be really appreciated.

  • Row Versioning Concurrency in SQL Server

    The optimistic concurrency model assumes that several concurrent transactions can usually complete without interfering with each other, and therefore do not require draconian locking on the resources they access. SQL Server 2005, and later, implements a form of this model called row versioning concurrency. It works by remembering the value of the data at the start of the transaction and checking that no other transaction has modified it before committing. If this optimism is justified for the pattern of activity within a database, it can improve performance by greatly reducing blocking. Kalen Delaney explains how it works in SQL Server.

  • As a consultant, how can I amaze my clients?

    - by user20326
    I am about to form a small consulting company and with a few friends and I am curious about how/what you do to amaze and create happy long lasting clients? This is of course besides the standard points like delivering on time, charge fair amount, deliver quality, and deliver what they really want. What other techniques do you use to amaze and create long lasting clients? (and to stand out compare to the competition) For example: Gifts? Happening and events? Night out at the pub?

  • Multiplayer in a game. How to design it object wise?

    - by Ninetou
    I was suggested on StackOverflow to ask this question here. I'm working on a simple game and I was thinking of adding multiplayer feature but I'm a bit stuck. I'm not sure what approach should I take, keeping in mind good programming practices. I have a Player object which is created for each player but then I have many other classes that would have to be able to access them. The thing is, if I initialise them in, let's say my main method, then I can't relate to different instances of player class from other classes. The only solution to my problem that comes to my mind is using some form of global objects but afaik using anything globally in apps is usually not a good practice. Any suggestions/ideas?

They were right, (1 dollar equals 0.73 euros). However, it stops working properly when the dollar input value is higher than $1363. This is what I get with $1364: $1364 = 1 000,64 €. I don't know what to do, will someone please help me? Thanks. decimal toEuro; Val.doy = "$" + decimal.Parse(richTextBox1.Text); //Ignore this, it's for the output form CultureInfo eu = new CultureInfo("fr-FR"); toEuro = decimal.Parse(richTextBox1.Text.Trim()); toEuro = toEuro * 0.73361m; richTextBox1.Clear(); Val.duh = toEuro.ToString("C2", eu);
