  • Which simple Java JPA ORM tool to use ?

    - by Guillaume
    What Java ORM library implementing JPA that match following criteria would you recommend and why ? free & open source alive (at least bug fixes and a mailing list) with good documentation simple not hibernate (this one is well-known :-) ) I need to select a simple ORM tool that can be set up in minutes without and easy to understand for setting simple CRUD daos. A query builder ill be an interesting plus. Later I can have to move to Hibernate, that's why being JPA compliant is a must. I have found some candidates on the web, but not so much feedback, so I will gladly take your advices on the topic. ----- EDIT --------- I have been successfully testing ebean/avaje with a small test cases. Any one has a feedback on using this tool in production ?

  • Center Pictures and Other Objects in Office 2007 & 2010

    - by Matthew Guay
    Sometimes it can be difficult to center a picture in a document just by dragging it dragging it around. Today we show you how to center pictures, images, and other objects perfectly in Word and PowerPoint. Note: For this tutorial we’re using Office 2010, but the steps are nearly identical in 2007. Centering a Picture in Word First let’s insert a picture into our document.  Click the Insert tab, and then click Picture. Once you select the picture you want, it will be added to your document.  Usually, pictures are added wherever your curser was in the document, so in a blank document it will be added at the top left. Also notice Picture Tools show up in the Ribbon after inserting an image. Note: The following menu items are available in Picture Tools Format tab which is displayed when you select the object or image you’re working with. How do we align the picture just like we want?  Click Position to get some quick placement options, including centered in the middle of the document or on the top.    However, for more advanced placement, we can use the Align tool.  If Word isn’t maximized, you may only see the icon without the “Align” label. Notice the tools were grayed out in the menu by default.  To be able to change the Alignment, we need to first change the text wrap settings. Click the Wrap Text button, and any option other than “In Line with Text”.  Your choice will depend on the document you’re writing, just choose the option that works best in the document.   Now, select the Align tools again.  You can now position your image precisely with these options. Align Center will position your picture in the center of the page widthwise. Align Middle will put the picture in the middle of the page height-wise. This works the same with textboxes.  Simply click the Align button in the Format tab, and you can center it in the page. And if you’d like to align several objects together, simply select them all, click Group, and then select Group from the menu.   Now, in the align tools, you can center the whole group on your page for a heading, or whatever you want to use the pictures for. These steps also work the same with Office 2007. Center objects in PowerPoint This works similar in PowerPoint, except that pictures are automatically set for square wrapping automatically, so you don’t have to change anything.  Simply insert the picture or other object of your choice, click Align, and choose the option you want. Additionally, if one object is already aligned like you want, drag another object near it and you will see a Smart Guide to help you align or center the second object with the first.  This only works with shapes in PowerPoint 2010 beta, but will work with pictures, textboxes, and media in the final release this summer. Conclusion These are good methods for centering images and objects in Word and PowerPoint.  From designing perfect headers to emphasizing your message in a PowerPoint presentation, this is something we’ve found useful and hope you will too. Since we’re talking about Office here, it’s worth mentioning that Microsoft has announced the Technology Guarantee Program for Office 2010. Essentially what this means is, if you purchase a version of Office 2007 between March 5th and September 30th of this year, when Office 2010 is released you’ll be able to upgrade to it for free!

  • Is donationware a good monetization model for developers?

    - by Nathan Campos
    I've been developing for Android for about 2 years (and ~1 year for iOS), releasing freeware and open source applications (mostly because my AdSense account was disabled in 2010), but recently I had an idea for a great app that I wanted to get some money, since it would take some effort to develop and also I would like to test this "commercial" model to know if this could make me invest more time improving and making my apps better. Since my AdSense account was disabled and then I'll not be about to sell it on the Google Play Store, I thought about making it a donationware so I would distribute it for free (and probably open source too) and users that really liked the app and wanted to give me a thanks and a incentive to continue developing it could donate any amount of money. So, what's your experience with donationware? Is it worth compared to paid apps?

  • How does one improve one's problem-solving ability?

    - by gcc
    How can one improve one's problem-solving ability? Everyone says same thing: "a real programmer knows how to handle real problem." But they forget how they learn this ability, or where (I know in school, no one gives us any ability, of course in my opinion). If you have any idea except above ones, feel free when you give your advice solve more problems do more exercises, write code, search google then write more ... For me, my question is like "use complex/known library instead of using your own." In other words, I want your personal experience, book recommendation, webpage on problem solving. Moreover, look your problem-solving method and give us your personal ability as if it is an algorithm

  • How can I improve overall system performance?

    - by Decio Lira
    What are your tips for improving overall system performance on ubuntu? Inspired by this question I realized that some default settings may be rather conservative on Ubuntu and that it's possible to tweak it with little or no risk if you wish to make it faster. This is not meant to be application specific (e.g. make firefox load pages faster), but system wide. Preferably 1 tip per answer, with enough detail for people to implement it. A couple of mine would be: Install Preload (via Software Center or sudo apt-get install preload); Change Swappiness value - "which controls the degree to which the kernel prefers to swap when it tries to free memory"; What are yours? PS: Since this is not intended to have a unique answer but rather, several useful tips, I'm making this community wiki out-of-the-box.

  • How do programmers deal with Project Lead/Managers?

    - by Simon
    Project Managers/Technical Leads sometimes tend to be over enthusiastic when it comes to software. But during code reviews if instead of functionality of the code the only complain one hears is about formatting/spacing and similar trivial things, when there are far better things to discuss (Among other things I have noticed the sometimes during the so called "reviews" suggestions are made that implementation needs a re-write just because it doesnt use the most happening technology/buzzword) How do fellow programmers deal with such scenarios? or is this just a one off? (or is the fault entirely on me )If you have similar experience and what you did to overcome it? Feel free to share.

  • Oracle Database 11g Helps Control Exponential Data Growth

    - by [email protected]
    The 2010 ESG annual customer survey is now available. As part of it, ESG interviewed 300 customers about their IT priorities and, unsurprisingly, "Manage Data Growth" is top of the list. Perhaps less self-evident is the proposed solution to target this prime concern: "Often overlooked because it is a database platform, Oracle Database 11g offers additional capabilities such as automatic storage management (ASM), advanced data compression, and data protection that make managing data growth much easier for organizations of any size." The paper goes on to discuss these capabilities and highlights their potential benefits. Oracle Database 11g Helps Control Exponential Database Growth - a worthwhile read for anyone having to deal with rapidly increasing amounts of data. Download your free copy here.

  • Why don’t UI frameworks use generics?

    - by romkyns
    One way of looking at type safety is that it adds automatic tests all over your code that stop some things breaking in some ways. One of the tools that helps this in .NET is generics. However, both WinForms and WPF are generics-free. There is no ListBox<T> control, for example, which could only show items of the specified type. Such controls invariably operate on object instead. Why are generics and not popular with UI framework developers?

  • WidgetBlock Speeds Up Browsing by Removing Social Media Widgets

    - by Jason Fitzpatrick
    Chrome: If you’re tired of web pages cluttered with social media buttons, WidgetBlock bans the buttons and speeds up the load time of web pages in the process. Even on a snappy internet connection you’ve likely noticed, thanks to the deluge of social media buttons loading in the background, a noticeable lag on popular web sites. WidgetBlock blocks widgets from loading (just like popular ad blocking software blocks ads from loading). The above screenshot, taken from a popular media site, shows just how much screen real estate is taken up by social media widgets.

  • Geez &ndash; do you even do basic testing?

  • Record Screen Activity with CamStudio

    - by Asian Angel
    Sometimes a visual demonstration works much better than a list of instructions. If you need to make a demo video for family and/or friends then you might want to have a look at CamStudio. Using CamStudio To get properly set up you will need to install two different files (the main program followed by the codec). Once that is done you are ready to get started. When you start the program you will see a surprisingly small window. Notice the highlighted Record to text…it serves as a visual indicator for the video type selected for recording. Before you start creating a video it would be a good idea to look through some of the settings. The first one to look at is the region or area that you want to record. Next you will want to look through the video options since these will affect the quality and final size of your video files. The default setting for quality is 70…adjust that to the level that best suits your needs. Note: For our example we maxed out the various video settings for best quality. On our system Microsoft Video 1 was listed as the default compressor but as you can see there were other options available. You can configure the settings for the compressor you want to use if desired. Keep in mind that each compressor will have unique settings of their own, so if you change it, be certain to go back and check. We decided to use the CamStudio Lossless Codec for our example (it gave the best results while trying the software). Going back to the main window you can toggle back and forth between .avi and .swf output using the last button. Once you are satisfied with the settings click on the red record button to start. If you need to pause while recording or stop recording click on the system tray icon and select the appropriate command. When you are finished recording, you will be presented with the save file window. Browse for the desired save location and name your new file. Once you have saved the file the movie player window will automatically open so that you view your new video. Our sample video shown here is at 50% of original size so may look slightly “gritty”. The detail was much better at 100%. If you decide to record and save as .swf the process will be identical to recording in .avi format until the movie player window opens. At that time the conversion process from .avi to .swf will begin. When complete you will have a new flash video and html file that goes with it. Depending on which browser you have set as default, you may run into a small problem when the preview for your new .swf file tries to open. There is a small bug in the generated html file. You can use this work-around or… Just open the .swf file directly in your favorite browser. Conclusion CamStudio may not produce the highest quality videos, but it’s free and does a very nice job nonetheless. If you are working on a tight budget or only need to make an occasional video then CamStudio is a very sensible choice.

  • College Courses through distance learning

    - by Matt
    I realize this isn't really a programming question, but didn't really know where to post this in the stackexchange and because I am a computer science major i thought id ask here. This is pretty unique to the programmer community since my degree is about 95% programming. I have 1 semester left, but i work full time. I would like to finish up in December, but to make things easier i like to take online classes whenever I can. So, my question is does anyone know of any colleges that offer distance learning courses for computer science? I have been searching around and found a few potential classes, but not sure yet. I would like to gather some classes and see what i can get approval for. Class I need: Only need one C SC 437 Geometric Algorithms C SC 445 Algorithms C SC 473 Automata Only need one C SC 452 Operating Systems C SC 453 Compilers/Systems Software While i only need of each of the above courses i still need to take two more electives. These also have to be upper 400 level classes. So i can take multiple in each category. Some other classes I can take are: CSC 447 - Green Computing CSC 425 - Computer Networking CSC 460 - Database Design CSC 466 - Computer Security I hoping to take one or two of these courses over the summer. If not, then online over the regular semester would be ok too. Any help in helping find these classes would be awesome. Maybe you went to a college that offered distance learning. Some of these classes may be considered to be graduate courses too. Descriptions are listed below if you need. Thanks! Descriptions Computer Security This is an introductory course covering the fundamentals of computer security. In particular, the course will cover basic concepts of computer security such as threat models and security policies, and will show how these concepts apply to specific areas such as communication security, software security, operating systems security, network security, web security, and hardware-based security. Computer Networking Theory and practice of computer networks, emphasizing the principles underlying the design of network software and the role of the communications system in distributed computing. Topics include routing, flow and congestion control, end-to-end protocols, and multicast. Database Design Functions of a database system. Data modeling and logical database design. Query languages and query optimization. Efficient data storage and access. Database access through standalone and web applications. Green Computing This course covers fundamental principles of energy management faced by designers of hardware, operating systems, and data centers. We will explore basic energy management option in individual components such as CPUs, network interfaces, hard drives, memory. We will further present the energy management policies at the operating system level that consider performance vs. energy saving tradeoffs. Finally we will consider large scale data centers where energy management is done at multiple layers from individual components in the system to shutting down entries subset of machines. We will also discuss energy generation and delivery and well as cooling issues in large data centers. Compilers/Systems Software Basic concepts of compilation and related systems software. Topics include lexical analysis, parsing, semantic analysis, code generation; assemblers, loaders, linkers; debuggers. Operating Systems Concepts of modern operating systems; concurrent processes; process synchronization and communication; resource allocation; kernels; deadlock; memory management; file systems. Algorithms Introduction to the design and analysis of algorithms: basic analysis techniques (asymptotics, sums, recurrences); basic design techniques (divide and conquer, dynamic programming, greedy, amortization); acquiring an algorithm repertoire (sorting, median finding, strong components, spanning trees, shortest paths, maximum flow, string matching); and handling intractability (approximation algorithms, branch and bound). Automata Introduction to models of computation (finite automata, pushdown automata, Turing machines), representations of languages (regular expressions, context-free grammars), and the basic hierarchy of languages (regular, context-free, decidable, and undecidable languages). Geometric Algorithms The study of algorithms for geometric objects, using a computational geometry approach, with an emphasis on applications for graphics, VLSI, GIS, robotics, and sensor networks. Topics may include the representation and overlaying of maps, finding nearest neighbors, solving linear programming problems, and searching geometric databases.

  • Here we go again - quest for web hosted forum via javascript

    - by jim
    Hello all, disclaimer If this is the wrong location for this question, then please advise me accordingly. backgound I've been using Disqus and intense debate as a 'comments' service for a variety of my sites to great effect and love the fact that i get alot of the facebook/twitter integration 'for free', as well as the SEO benefits. request To this end, does anyone out there know of similar services that can be used to pull entire forums/threaded discussions into the app in a similar fashion (i.e. via ajax webservices). google has been at a loss to turn anything up on this front and i'm therefore wondeing if it's unlikely that such a 'service' exists. respect hope this stikes a chord out there... btw - altho using this in asp.net mvc, I'm aware that this technology could be used on any platform capable of consuming javascript via ajax, thus the wide spread of 'tags'.
