• APress Deal of the Day - 13/Apr/2012 - Pro WPF and Silverlight MVVM

  - by TATWORTH

  The APress $10 deal of the day for today is "Applied WPF 4 in Context" (http://www.apress.com/9781430234708) starts with a simple introduction to WPF and then shows a complete WPF application from sketch to completed code. This APress web site states "This book can be used by a junior developer to learn WPF and understand how to architect a layered application, and it can also be used by a senior developer as a reference for developing scalable WPF applications. " - this summerises the book very effectively as it is indeed an excellent book both for learning WPF and as a reference for development. I recommend it to all Dot Net development teams.

• Performance impact of not implementing relationships at the database level?

  - by JVerstry

  Let's imagine a data model with customers and invoices. There is a 1 to n relationship between a customer and its invoices. We uses an ORM (like Hibernate). One can explicitely implement the 1-n relationship (using JPA for example) or not. If not, then one must do a bit more work to fetch invoices. However, it is much easier to maintain, improve and develop the data model of applications where relationships between objects are not explicitely implemented in the database. My question is, has anyone noticed a significant performance impact when not implementing the relationships in the database?

• Lost power during upgrade, how do I recover?

  - by Ryan McClure

  I was attempting to update my 11.10 install to 12.04beta. During the install step, I accidentally lost power to my laptop (the power cable came unplugged) and it shut down. Whenever I go to boot now, I can select my install via Grub and it loads up to where the sign-in should happen, but I get a display that looks like what you see as soon as you shut down. It looks like it locks after checking for the battery. Is there anyway, with or without Live media, to restore my machine's install/update to 12.04 but still keep my settings/applications/files?

• Chrome 18 : la 3D pour tous et amélioration de l'accélération de Canvas2D

  Chrome 18 : la 3D pour tous Et amélioration de la prise en charge de Canvas2D Chrome 18 vient de passer en version stable. Au menu, une amélioration de la prise en charge de Canvas2D qui tire parti de l'accélération matérielle (et du GPU donc). Elle devrait permettre à des applications web, comme les jeux, de tourner plus rapidement. Pour Google, avec cette prise en charge, les versions 100% Web des applicatifs pourraient même être aussi performantes que les versions traditionnelles. L'accélération matérielle appliquée à Canvas2D était jusqu'ici réservée au « beta channel » de Chrome. La fonctionnalité peut donc avoir encore quelques petits ratés. [IMG]http:/...

• Do Java applets have any place on the web today?

  - by Tom Marthenal

  Many browsers now disable Java applets by default, requiring them to be enabled on a per-page basis. It seems like applets have not changed much in the past few years. In fact, it seems that client-side Java (applets, desktop applications, ...) is dying completely, and Java is primarily becoming a server-side language. Except for the sake of compatibility, is there any place where applets are still useful on today's web? As a web developer who is familiar with Java and with JavaScript, why would I ever choose to use an applet instead of some JavaScript?

• Samsung a-t-il triché sur les benchmarks pour le Galaxy S4 ? Les performances de l'Exynos 5 remises en cause après des tests

  Samsung : les Galaxy S4 affichent des performances élevées pour les benchmarks Mais moindres pour les autres applicationsTout a débuté avec le post d'un utilisateur mécontent sur le site Beyond3d après qu'il ait réalisé des bancs d'essai pour le GPU de son Galaxy S4. Pendant les essais, l'utilisateur constate que le GPU de son smartphone tourne à 532 Mhz. Cependant, pour toutes les autres applications y compris les jeux (aux résolutions les plus poussées) ce dernier ne tournerait plus qu'à 480 Mhz. « Oh Samsung honte à toi ! » écrira-t-il.Par la suite, Brian Klug et Anand Lal Shimpi, du site web Anandtech, reprennent eux aussi l'expérience de cet utilisateur avec leurs propres smartphones pour en confirmer...

• Le Mac App Store est ouvert depuis ce matin, mais il inquiète déjà certains développeurs

  Le Mac App Store est ouvert depuis ce matin, mais il inquiète déjà certains développeurs Mise à jour du 06.01.2011 par Katleen Comme nous vous l'avions annoncé il y a deux semaines, le Mac App Store est lancé ce jour. Un service de plus dans la panoplie d'Apple, qui ne cesse de s'étendre. Son objectif ? Offrir plus de visibilité à Mac OS X, l'OS de la firme. La boutique sera en effet disponible directement depuis celui-ci. Seulement, ce concept ne fait pas la joie de tout le monde : les développeurs commencent à grincer des dents. En effet, à cause de la prolifération des applications, qui sont de plus en plus nombreuses, un phénomène de concurrence s'est mis en place, e...

• Gnome/X logs off immediately after login -- which logfiles are relevant?

  - by joebuntu

  I've been tinkering with fingerprint-gui as well as X/xrandr resolution settings. When I start my machine, it boots up normally. As soon as X and gnome have finished starting, it logs me off automatically and brings me back to the gdm login prompt with the user list. Then I am, however, able to log in using "Ubuntu Desktop Fail-safe". I've checked the list of start-up applications, but everything seems fine there. I can't yet put my finger on what exactly might be responsible for this: X, gnome or some messed up pam.d settings. So far I've checked /var/logs/X11/xorg.0.log, /var/logs/auth.log and ~/.xsession-errors. In addition, I don't quite seem to understand the "interplay" between X, GDM, GNOME, GNOME-policykit, PAM.d and all that. Are there any other relevant log files that could point me to what's broken? Specs: Ubuntu 10.10 Maverick Meerkat IBM/Lenovo Thinkpad R60, ATI Radeon x1400 Mobility all updates installed Linux User 1 year+,

• Enhancing Enterprise Planning and Forecasting Through Predictive Modeling

  Planning and forecasting performance in today's volatile economic environment can be challenging with traditional planning applications and manual modeling techniques. To address these challenges, leading edge companies are leveraging predictive modeling to bring statistical analysis and techniques such as Monte Carlo simulations into the mix. Sound too math-intense and complicated? Not anymore. These techniques can be applied by anyone - no prior stats experience required - whether to augment the forecasting performed by line managers or to validate those forecasts based on historical information, and to produce a broader range of scenarios to consider in decision-making.

• C# on ubuntu 12.04

  - by Deus Deceit

  Is C# a good choice for ubuntu programming? E.g unity, or applications that will run on ubuntu? Am I doing good wanting to learn C# when I'm determined to stick with ubuntu and develop on it or for it? If not, can you give me reasons why? And which languages would be better than c# for ubuntu development? I already know c, c++, java(basics), php, mysql, python(basics). I like to learn new stuff, but stuff that worth my time. Does C# worth my time? If c# worth my time, here's what I have done and what I need: I installed all mono packages I could find on the ubuntu standard repositories. Now I want a good tutorial to get me started. I'm a complete noob with c# so a basic tutorial and how to compile run under ubuntu 12.04 would be great.

• How could I manage Google Adsense to approve my Web App? It keeps denying it

  - by Javierfdr

  Google adsense keeps denying my app from having ads, because of an "insufficient content" issue. I manage a Web Application that allows the users to set Youtube Videos as Alarm Clocks. It includes an in-site Youtube search to retrieve videos from user queries and lists the users alarms. The site has a good traffic (500 users per day), is currently promoted by Google in Google Chrome Webstore, and the ajax requests are crawlable, following Google's guidelines (https://developers.google.com/webmasters/ajax-crawling/). Although I understand there is not much content, beyond the user-generated, I really don't what else should I include in the site. Perhaps adding contact and about pages, and maybe another section would increase the navigation. Google argues I need a "fully launched and functioning site, allowing users to navigate throughout your site with a menu, sitemap, or appropiate links". They also ask for "full sentences or paragraphs" Isn't a Google Adsense solutions for Web Applications? Would all the web-apps have to include useless navigable subpages?

• How to get experience in large scale databases?

  - by Justin

  I have written applications that are very small scale and the code I write works fine for them. But I have often wondered how the server side code I write would scale up from 100s of queries per day to millions. Also when looking at possible jobs/projects, people are often looking for developers with experience in this sort of high traffic database design so I would at least like to be able to say, I havent gotten to work on a project that was this popular, but I at least have tried to simulate it. Are there tools or frameworks that can generate a lot of traffic or at least simulate what would happen with traffic on different orders of magnitude so I could get some practice writing optimized code for higher traffic applicaitons?
