• Why do i keep forgetting things? [closed]

  - by Mr.Anubis

  I am currently learning many things at the same time in C++ and coded many data structures and algorithms and some small applications. When I suddenly try to remember something that I coded many months ago, my mind completely goes blank. It's like I'll have to re-learn the whole thing. For example, recently I was thinking to refactor my BST data structure, when I realized that I don't even remember how I coded it or how does it works internally. Does this happen with many others? Or is it me only? How do I overcome this problem?

• Compiz Error After Emerald Install

  - by KoopaTroopa

  Salutations! So, once again, I fell to the allure of the window decorator emerald. Where, just like the first time around, (I know I know) upon attempting to back out of emerald to the safety of compiz I'm faced with a problem. Seemingly after several minutes or after opening Chrome any window that isn't maximised has it's borders removed (so there's no close, minimise and maximise etc buttons). I can get them breifly back if I reload compiz via fusion-icon. After a brief chat on IRC it appears compiz is crashing. Here's a pastebin log of me running compiz via terminal. http://pastebin.com/sK65v4Fi I forgot my two vows of 'Never bother using Windows applications via wine or a VM' and 'Thou shalt never not use compiz'. ***GTK-Window-Decorator log gtk-window-decorator (gtk-window-decorator:11027): Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap", Segmentation fault ** also posted on ubuntuforums to widen my scope of help.

• How to quantify product work in Resume?

  - by mob1lejunkie

  One of things I do in my Resume is try to quantify the impact my work has had in the particular company I was with at the time. The reason is it shows the value my work had added to the business. Is this what you guys do as well or am I the only one? In my previous job this was easy as I worked on short/medium internal applications and it was fairly easy to measure end result. For example, external consulting company quoted $50,000 for an application Business Services department wanted I completed it in 3 days so I say I saved the company $48,000. I have been in my current job for 3 years but all of it has been on 1 single well established product. About 30% work is maintenance and 70% work is on new modules. I have worked on various modules like API (WCF), Security (2 factor authentication), etc. How should I quantify work on modules? Many thanks.

• On-line Based Conferencing For Admin Panel

  - by Tim Marshall

  Working on my admin panels work station section which will allow the admin to use simple office tools such as word editors, calculators and whatnot. Under this section of the admin panel, I would like to add a conferencing feature which will allow any administrator to connect with another administrator 1-2-1 under the 1-2-1 Conferencing section, or to join a meeting under 'live meeting' section. Upon my search for on-line based, I found there are all these, what seem to be great applications out there, however not all of them are on-line based, and come with a price! I would like to a purely on-line based conferencing/meeting/1-2-1 feature which will allow administrators to communicate via text or sound, stream their video, share their screen and sending of files. I know this sounds like a big feature, and I am not asking for someone to answer by programming one for my website! Does anyone know my best solution to progress to having this feature on my website, any tutorials or free to use, free to modify web plugins? Thank you for your help, Best Regards, Tim

• Introduction to JBatch

  - by reza_rahman

  It seems batch processing is moving more and more into the realm of the Java developer. In recognition of this fact, JBatch (aka Java Batch, JSR 352, Batch Applications for the Java Platform) was added to Java EE 7. In a recent article JBatch specification lead Chris Vignola of IBM provides a high level overview of the API. He discusses the core concepts/motivation, the Job Specification Language, the reader-processor-writer pattern, job operator, job repository, chunking, packaging, partitions, split/flow and the like. You can also check out the official specification yourself or try things out with the newly released Java EE 7 SDK.

• Writing a Data Access Layer (DAL) for SQL Server

  In this tip, I am going to show you how you can create a Data Access Layer (to store, retrieve and manage data in relational database) in ADO .NET. I will show how you can make it data provider independent, so that you don't have to re-write your data access layer if the data storage source changes and also you can reuse it in other applications that you develop.

• Why would I want to use CRaSH?

  - by Adam Tannon

  Justed stumbled across CRaSH and although it looks mighty interesting, I'm wondering why a Java developer should invest time & energy into learning (yet another) shell language. What sort of standard- and cool-applications can CRaSH be used for? Is this like a Groovy-version of Jython? I guess, when the dust settles, I'm looking for CRaSH's "wow" factors. I'm sure they're there, but after spending ~20 minutes perusing the documentation I'm just not seeing them. Thanks in advance!

• How can I fix my problems with fonts in Firefox?

  - by snostorm

  Ever since I reinstalled Ubuntu a few hours ago, I've experienced major visual artifacts with smaller font sizes in Firefox. The fonts end up looking like this: Or even like this: This only occurs in Firefox; other applications are unaffected. It also occurred on the LiveUSB I used for installation, making me suspect a hardware or driver issue. The output of lshw on my computer is here: http://pastebin.com/LnSt6veT. Any idea what might be causing this, or how I can fix it? ... and "Use Google Chrome" is not a valid answer. ;)

• How can an application (like Firefox) be forced to use a certain network interface?

  - by Lekensteyn

  I've two interfaces: eth0 and wlan0 on a notebook. Possible use cases: eth0 grants me Internet access, and wlan0 is currently connected to a router which does not have Internet-connectivity. For development purposes, I need to connect to the wlan0 by default, but use eth0 for surfing eth0 and wlan0 are both connected to the Internet. For a torrent application, eth0 should be used for speed, but for portability of the notebook, SSH should have a connection over wlan0 eth0 is a wire connection, wlan0 is a wireless one. Sensible data should be transferred over eth0, but other traffic can go over wlan0 as well. Is there a way to force applications (like nc.traditional or firefox) to use a certain network interface? A wrapper like example-wrapper eth0 program is fine too if such program exist. It would be nice if it could configured within Firefox (in runtime). I'd like to avoid IPTables solutions if possible.

After having installed it using alt+f2 and having used gksudo nautilus I have installed MATLAB in the correct folder which is: /usr/local/MATLAB/R2012a Then I inserted the license and the window told "activation complete" or something like that. This made me happy, but only for a while because as soon as I try to search for Matlab within the applications I cannot find it and neither if I try to run matlab into terminal it says: command not found Can someone help me!?

• Petstore using Java EE 6 ? Almost!

  - by arungupta

  Antonio Goncalves, a Java Champion, JUG leader, and a well-known author, has started building a Petstore-like application using Java EE 6. The complete end-to-end sample application will build a eCommerce website and follows the Java EE 6 design principles of simple and easy-to-use to its core. Its using several technologies from the platform such as JPA 2.0, CDI 1.0, Bean Validation 1.0, EJB Lite 3.1, JSF 2.0, and JAX-RS 1.1. The two goals of the project are: • use Java EE 6 and just Java EE 6 : no external framework or dependency • make it simple : no complex business algorithm The application works with GlassFish and JBoss today and there are plans to add support for TomEE. Download the source code from github.com/agoncal/agoncal-application-petstore-ee6. And feel free to fork if you want to use a fancy toolkit as the front-end or show some nicer back-end integration. Some other sources of similar end-to-end applications are: • Java EE 6 Tutorial • Java EE 6 Galleria • Java EE 6 Hands-on Lab

• How to shrink Windows partition with unmovable files in dual boot installation

  - by Tim

  To install Ubuntu alongside Windows 7, I have to shrink Windows 7 partition C:. But due to some unmovable files, I cannot shrink as much as I plan by using Windows own shrinking tool. I guess many of you who have both OSes on the same hard drive must have similar experience. How to solve this problem? Any reference that can help is also appreciated! Thanks and regards! UPDATE: I have identified what unmovable file currently stop further shrinking: \ProgramData\Microsoft\Search\Data\Applications\Windows\Projects\SystemIndex\Indexer\CiFiles\00010015.wid::$DATA If I understand correctly, the file belongs to Windows Search. Can I set up somewhere in Windows system settings to temperately eliminate the file and similar ones (because there are many similar files under the same directory which I guess will also stand in the way of shrinking and unmovable by defrag)?

• Crafting an effective php/web programmer job post template [closed]

  - by Tchalvak

  I am looking to create a job post to get a satisfactory assistant programmer / templater. Specifically, a php & web programmer. I am, however, afraid of forgetting important things. So, are there resources you can suggest for templates for things to ask and things to tell in a job post for a programmer? Surprisingly, I wasn't able to find similar questions on this site, so there may be duplicate questions out there that I could use but just didn't find. Right now I know that my -requirements- are so generic that they're going to get me in trouble with a spam of applications. e.g. the candidate must know php, must be able to seperate php from html. So I'm looking for criteria that are must-haves, must-mentions, or a general template to try to avoid a "lemon". I also started a gist to work on a job post, comments/edits would be excellent: https://gist.github.com/2906808

• RTOS experience

  - by Subbu

  I have been working as an embedded software engineer on mostly 8 bit micro-controller firmware and desktop/mobile applications development for the past five years. My work on a WinCE project (in which I got introduced to .NET CF) was short lived. I did use core APIs for interrupt processing, peripheral communication, etc...but again, not exactly a pure RTOS environment. In order to get together more solid experience for growing more in the embedded field, I want to work more with RTOSes. Will buying an evaluation board with an RTOS and putting together a project at home be regarded as a good experience or will an online course be more useful? I am just not clear as to what will be regarded as good experience. Any suggestions or directions will greatly help me. I have a passion for the field but just a need a point in the right direction.

• Topics for covering in-depth programming knowledge

  - by black_belt

  I pursued my bachelors' degree in business administration, but my interest in Information Technology led me to acquire some knowledge of PHP programming and MySQL database. I find programming so interesting that I haven't applied for any job since my graduation. Currently I am staying home and just trying to acquire in-depth knowledge of PHP programming. So far I have developed couple of websites and web applications including Inventory+ Point of Sale Software and an Accounting system for small organizations. I aim to have knowledge that a Computer Science graduate should have, and for that I want to read books but I have no idea where to start from. Could you please suggest me some books and topics that I should study on? Thanks a lot :)

• Type Conversion in JPA 2.1

  - by delabassee

  The Java Persistence 2.1 specification (JSR 338) adds support for various new features such as schema generation, stored procedure invocation, use of entity graphs in queries and find operations, unsynchronized persistence contexts, injection into entity listener classes, etc. JPA 2.1 also add support for Type Conversion methods, sometime called Type Converter. This new facility let developers specify methods to convert between the entity attribute representation and the database representation for attributes of basic types. For additional details on Type Conversion, you can check the JSR 338 Specification and its corresponding JPA 2.1 Javadocs. In addition, you can also check those 2 articles. The first article ('How to implement a Type Converter') gives a short overview on Type Conversion while the second article ('How to use a JPA Type Converter to encrypt your data') implements a simple use-case (encrypting data) to illustrate Type Conversion. Mission critical applications would probably rely on transparent database encryption facilities provided by the database but that's not the point here, this use-case is easy enough to illustrate JPA 2.1 Type Conversion.

• Which language is productive for high phase business application development? [closed]

  - by Nizar

  If we (I and my friends) would like to build web-based products and sell it using a license approach (to renew every year for example). Which server-side language will be most suitable for our purpose? We could target the following audience: - Personal sites. - Serious small-medium companies (to sell prducts such as Help-Desks, Forms,etc.) - Restaurants (to sell online order web applications). We would like to - attract as many customers as possible. - provide updates for our prodcuts (for our customers). - make our products easy to use. There are number of open-source frameworks and languages that has potential to handle our business problems (like Django, Python, Java, etc..) However, we are not sure which one is easier to learn and has variety of tools/plugins to help us in development process. Thus we need to get you experience on this hard to decide matter. Which language and its supporting framework we should choose ?

• Useful design patterns for working with FragmentManager on Android

  - by antman8969

  When working with fragments, I have been using a class composed of static methods that define actions on fragments. For any given project, I might have a class called FragmentActions, which contains methods similar to the following: public static void showDeviceFragment(FragmentManager man){ String tag = AllDevicesFragment.getFragmentTag(); AllDevicesFragment fragment = (AllDevicesFragment)man.findFragmentByTag(tag); if(fragment == null){ fragment = new AllDevicesFragment(); } FragmentTransaction t = man.beginTransaction(); t.add(R.id.main_frame, fragment, tag); t.commit(); } I'll usually have one method per application screen. I do something like this when I work with small local databases (usually SQLite) so I applied it to fragments, which seem to have a similar workflow; I'm not married to it though. How have you organized your applications to interface with the Fragments API, and what (if any) design patterns do you think apply do this?
