• Le W3C publie un premier brouillon de l'API Push, qui permettra d'intégrer des notifications Push au sein des applications Web

  Le W3C publie un premier brouillon de l'API Push qui permettra d'intégrer des notifications Push au sein des applications Web Le groupe de travail Web Applications du W3C (World Wide Web Consortium) vient de publier un brouillon pour l'API Push. La spécification Push API décrit la façon dont un serveur d'applications peut envoyer des données cryptées (messages Push) à des applications Web côté client, telles qu'elles sont effectuées par des « services Push ». L'API pourra être utilisée par les développeurs pour mettre en oeuvre des systèmes de notifications Push au sein de leurs Webapps. Selon la description du W3C, le message Push pourra être envoyé même si l'applic...

• What are good Software Project Management Texts / Resources?

  - by locster

  I'm looking for ideas and resources pertaining to software project management, specifically resources that I can direct project managers to in order to broaden their knowledge of the subject. So for example an obvious choice here would be The Mythical Man Month - I do think that this would be an appropriate suggested first read for /some/, but not all. Probably for managers that arrive at the job with more of a management background rather than a technical one TMMM might be a bit 'heavy'. I'm looking for similar texts that convey more or less the same messages, but perhaps in a form more appropriate for people from a wide range of backgrounds. Thanks.

• Multi Column Block Too Narrow in Chrome

  - by aksarben

  My Web site displays song lyrics in a multi-column format, using CSS3. Both Firefox & MSIE 10+ display the multi-column text perfectly, but Chrome does not. This sample page shows the problem: http://www.hymntime.com/tch/test/html5/html5-multicolumn-test.htm The page uses a media selector, so your Chrome window must be at least 1280 pixels wide to see the effect. In fact, if you make the Chrome window less than 1280 pixels, you'll see the lyrics block change to a single column, of the same overall width. In other words, when Chrome shifts to 1-column to 2-column mode (due to the wider browser window), the lyrics block remains the same width, causing text to be squeezed together. Has anyone else seen this behavior, or know a solution? Is this a Chrome bug, or I am I doing something wrong? I posted this question on a Chrome forum a while back, but got no reply.

• What method do I use to manage an app-specific background process?

  - by Simon Dubois

  I am developing an application with different behavior depending on the arguments : "-config" starts a Gtk window to change options, start and close the daemon. "-daemon" starts a background process that does something every X minutes. I already know how to use fork/system/exec etc... But I would like to know the main logic of such application to : restart or refresh the daemon when configuration change. keep only one instance of the daemon. I have read that killing the daemon to restart it is not a clean way to do. How other applications do ? (ubuntuone, weather forecast, rss feed working with notification area) Thanks for your help. PS : I don't want to create a system-wide daemon, just a user application with a background process.

• Free book from Microsoft: - Exploring CQRS and Event Sourcing

  - by TATWORTH

  At http://www.microsoft.com/en-us/download/details.aspx?id=34774, Microsoft are providing a free book on Exploring CQRS and Event Sourcing"This guide is focused on building highly scalable, highly available, and maintainable applications with the Command & Query Responsibility Segregation and the Event Sourcing architectural patterns. It presents a learning journey, not definitive guidance. It describes the experiences of a development team with no prior CQRS proficiency in building, deploying (to Windows Azure), and maintaining a sample real-world, complex, enterprise system to showcase various CQRS and ES concepts, challenges, and techniques. The development team did not work in isolation; we actively sought input from industry experts and from a wide group of advisors to ensure that the guidance is both detailed and practical. "

• Is there a White / Blank Canvas E-Commerce Platform to Integrate into Existing Site? [closed]

  - by beta208

  Possible Duplicate: Which Ecommerce Script Should I Use? Our website is built we're interested in adding a Store to the site. Essentially, there is a global header, and a global footer, and in between is a white expandable div. We'd like our store to fit between the header and footer (and preferably be 960px wide). Do you know of any store platform built to live between the header/footer for situations like this? We really want a full store, not just paypal buy buttons. We'd like it to have a shop backend (CMS-like) with full tracking, etc. Can be paid or unpaid, and preferably hosted by us, but either might be applicable (if iframe or alternative works securely?). This would need to feature over 100 items. If authorize.net is supported that is a plus.

• Java : un choix coûteux pour les entreprises ? Oui, d'après un expert qui recommande de capitaliser sur les briques open-source

  Java est-il un choix coûteux pour les entreprises ? Oui, d'après un expert qui recommande de capitaliser à bon escient sur les briques open-source Quinze ans après l'émergence de Java, David Duquenne, Directeur Génétal du groupe Open Wide Technologies (spécialiste de l'intégration et des l'exploitation des logiciels en France) fait un bilan du langage, qu'il trouve plutôt mitigé. Un avis plutôt polémique. Selon lui, Java n'aurait pas tenu ses promesses. Les projets réalisés à l'aide de ce langage auraient la réputation d'être « trop subtils pour les développeurs (sic), coûteux à réaliser et complexes à maintenir». Le point de vue des Directions des ...

• What steps should be taken to make sure your software is usable by disabled people?

  - by Cromulent

  I want to make sure a piece of software I am writing is usable by people with various disabilities such as blindness and an inability to use a mouse and / or keyboard. Unfortunately I have no experience with things such as screen readers or other methods that disabled people use to make using a computer easier / possible. I've never really had much experience with disabilities at all and unfortunately I don't know any disabled people who I can ask. I was wondering what other people do to make sure that their software is available to a wide range of people with varying abilities? This seems to be a subject matter that is often ignored by developers and I think it is a real shame.

• HTG Explains: What is DNS?

  - by Chris Hoffman

  Did you know you could be connected to facebook.com – and see facebook.com in your web browser’s address bar – while not actually being connected to Facebook’s real website? To understand why, you’ll need to know a bit about DNS. DNS underpins the world wide web we use every day. It works transparently in the background, converting human-readable website names into computer-readable numerical IP addresses.

• How to setup VPN as Proxy

  - by Nicolas Nox

  I have an PerfectPrivacy VPN connected via the OpenVPN-Network-Manger-Plugin (Ubuntu 12.04.1) and I want to assign a system wide proxy over that VPN. I have tried proxydriver that should do that automatically, but it works partially. The browser says that I have the IP of the VPN, but when I tried to send an eMail over SMTP (Port 25), I can´t connect to the mail server. In our company the smtp server port is closed, but that should be not a problem, when I do that over a VPN, shouldn´t it? greetings

• Web hosting announced downtime and how it affects FORWARD domain names?

  - by maple_shaft

  Our web hosting provider that holds our FORWARD domain names announced that at some point in the next couple weeks they will be migrating servers and that this will cause a 5-10 minute downtime at some point in that week during what happens to be our core business hours. They cite for technical reasons it is impossible to give an exact date or time when this downtime will occur. My questions are: If my domains are set to FORWARD to a static IP on servers not hosted by the web hosting provider in question then will this affect the DNS servers correctly routing to my website? Are their legitimate technical reasons for such a wide window of time, or could this just be a blanket statement to cover laziness in not being more organized with their server migrations? Are such downtimes normal for web hosting providers, or should I start to consider other providers?

• How to make Nautilus name column display at the width of the longest filename

  - by fred.bear

  Prior to a recent glytch where I lost some of my custom settings, Nautilus would open directories and display the name-column wide enough to show the longest filename on display. It did it dynamically; If I renamed a file to a longer or shorter name, the column was automatically adjusted to the new width.. It's not doing that now, and I have no idea how to get this function back.. UPDATE I hadn't mentioned it, but I am talking about the List view... I have been fossicing around in the GConf Editpr and came across a setting for Compact View which does exactly what I am referring to... but it only effects the Compact View... that setting is: gconf-editor /apps/nautilus/compact_view/all_columns_have_same_width ...but I can't find the setting for List View... I know the capability exists, because I've been using it until only a few days ago, when my system got hung up...

• URL parameter names being changed by user agents

  - by Mike Deck

  In reviewing one of our site's web logs I'm seeing instances where we are returning a 404 to requests because we're expecting an id parameter to be sent, but instead we're seeing a di parameter. The resource in question is an image but which image file actually gets served is dependent on the id parameter. The expected url is something like http://images.mysite.com/photo.gif?id=123&width=200&height=300 What I'm seeing in the logs is requests for http://images.mysite.com/photo.gif?di=123&width=200&height=300 The only case where we are seeing this on the id parameter. It seems unlikely that this is due to a server side or JavaScript bug since it seems to be only effecting a small percentage of our traffic. We are seeing this across a wide variety of user agents (both mobile and desktop) and IPs. Has anyone else seen this? Is there a browser plugin or other software you're aware of that could be causing this, and if so is there a good way to work around the issue?

• Lining things up while using columns

  - by Charles

  I have a request that may not be possible. I'd like to line up the elements of a form so that the inputs all start at the same place: Name: [ ] Company: [ ] Some question with a long name: [ ] But my list is (somewhat) long and I would like to show them in multiple columns on screens that are wide enough. Ideally, I'd find a POSH method (table-free is semantically appropriate, I think) that works on a reasonable number of browsers. My current page uses a table. I tried CSS with columns: auto; -moz-column-count: auto; -moz-column-width: auto; -webkit-column-count: auto; -webkit-column-width: auto; but Firefox (at least) won't break a table across columns.

• What is the good way of sharing specific data between ViewModels

  - by voroninp

  We have IAppContext which is injected into ViewModel. This service contains shared data: global filters and other application wide properties. But there are cases when data is very specific. For example one VM implements Master and the second one - Details of selected tree item. Thus DetailsVm must know about the selected item and its changes. We can store this information either in IAppContext or inside each concerned VM. In both cases update notifications are sent via Messenger. I see pros and cons for any of the approaches and can not decide which one is better. 1st: + explicitly exposed shared proerties, easy to follow dependencies - IAppContxt becomes cluttered with very specific data. 2nd: the exact opposite of the first and more memory load due to data duplication. May be someone can offer design alternatives or tell that one of the variants is objectively superior to the other cause I miss something important?

• How can I make a case for "dependency management"?

  - by C. Ross

  I'm currently trying to make a case for adopting dependency management for builds (ala Maven, Ivy, NuGet) and creating an internal repository for shared modules, of which we have over a dozen enterprise wide. What are the primary selling points of this build technique? The ones I have so far: Eases the process of distributing and importing shared modules, especially version upgrades. Requires the dependencies of shared modules to be precisely documented. Removes shared modules from source control, speeding and simplifying checkouts/check ins (when you have applications with 20+ libraries this is a real factor). Allows more control or awareness of what third party libs are used in your organization. Are there any selling points that I'm missing? Are there any studies or articles giving improvement metrics?

• Possible to pass pygame data to memory map block?

  - by toozie21

  I am building a matrix out of addressable pixels and it will be run by a Pi (over the ethernet bus). The matrix will be 75 pixels wide and 20 pixels tall. As a side project, I thought it would be neat to run pong on it. I've seen some python based pong tutorials for Pi, but the problem is that they want to pass the data out to a screen via pygame.display function. I have access to pass pixel information using a memory map block, so is there anyway to do that with pygame instead of passing it out the video port? In case anyone is curious, this was the pong tutorial I was looking at: Pong Tutorial

• Can I automatically make my Nvidia card's fan quieter?

  - by Salim Fadhley

  I have a machine with an Nvidia graphics card. Unfortunately the GPU fan is very loud. It's very annoying at times. We never use this machine for intense 3d work - that GPU is probably not working very hard at all. I'm pretty sure I can run it at a much lower fan-speed without causing any problems. The nvclock utility can be used to manually adjust the fan-speed of my Nvidia graphics card. I'd like to call this utility automatically when the machine boots up. Is there some kind of system service which I can use to automatically apply this kind of system-wide configuration? Even better, is there a system monitoring service which can poll the GPU temperature and adjust the various system fan-speeds accordingly? Thanks!

• How can I change resolution of "my video" in Skype?

  - by koushik

  I have a logitech Quickcam Pro 9000 connected to my ubuntu desktop and it works fine with Skype. However, Skype inputs and sends my video at the native (for the webcam I think) resolution of 1600 x 1200. I can confirm that the camera supports a wide variety of resolutions starting from 160 x 120 upto 1600 x 1200 (including e.g., 320 x 240, 352 x 288) using cheese. I can select these resolutions and see the output is appropriately scaled. Also, I don't see any improvements in smoothness of motion in the captured video so I suspect the original 1600 x 1200 is scaled down in the path somewhere. Is it possible to somehow to enable this scaling capability towards Skype?

• schema.org specification for generic pages or posts on a CMS

  - by NateWr

  I'm trying to determine the best possible schema.org type to declare for the content section in the template of a content management system, which will handle regular news posts for small, local hospitality businesses. The type should represent the content of that page, which is likely to be a wide range of things. The description for Article pretty strongly encourages its use to be limited to the articles of a publication. For purely semantic reasons, I'm not sure if Blog is appropriate in this case -- businesses won't be creating typical "blog" content but are more likely to be writing about upcoming events, special deals, awards, etc. Would Webpage be appropriate in this instance? Although I'm a fan of the schema.org concept, I frequently find myself unsure how broadly or narrowly I'm meant to infer the meaning of a type. In such cases, is it safe to use a high-level element, such as CreativeWork, or does this blunt the usefulness of the markup?
