• EJB Lifecycle and Relation to WARs

  - by Adam Tannon

  I've been reading up on EJBs (3.x) and believe I understand the basics. This question is a "call for confirmation" that I have interpreted the Java EE docs correctly and that I understand these fundamental concepts: An EJB is to an App Container as a Web App (WAR) is to a Web Container Just like you deploy a WAR to a Web Container, and that container manages your WAR's life cycle, you deploy an EJB to an App Container, and the container manages your EJB's life cycle When the App Container fires up and deploys an EJB, it is given a unique "identifier" and URL that can be used by JNDI to look up the EJB from another tier (like the web tier) So, when your web app wants to invoke one of your EJB's methods, it looks the EJB up using some kind of service locator (JNDI) and invoke the method that way Am I on-track or way off-base here? Please correct me & clarify for me if any of these are incorrect. Thanks in advance!

• Notebook overheating

  - by user71372

  I'm asking this question because I've tried many tips to solve they don't work and it sounds like a non-fixed bug ubuntu. My problem is with overheating. I've recently installed Ubuntu Precise 12.04 LTS alongside with MS Windows 7 on my notebook Samsung 530U. I'm using both via dual-boot mode. I've no heating problem with MS Win 7 and the fan speed is normal even with long run utilization. However, when booting with Ubuntu and after short time, the PC got very hot and the fan was running at max speed. I installed a tool called Jupiter, I put it in "Power Saving" mode but no result. Now, I avoid using ubuntu because I fear it'll damage my all new notebook. Please can you give me a "FINAL" fix of this problem (lot of answers exist but I don't know the more accurate and efficient one). Thank you in advance.

• Active - like-minded Java mailing lists

  - by Lewis Robbins

  I need to find an active Java mailing list, I have looked onto the GNU Java mailing list, to my surprise there had been not too much activity this month, it also focused on any GNU related Java - I'd really help me progress my Java ability, if I had an active, likeminded Java mailing list. Questions' that are not suited to Stackoverflow, or provide little benefit to any user that see's the question: discussing a new API change; best practices; open source discussion; trivia type questions on Java ArrayList boxining-unboxing; Community atmosphere. I also read Jon Skeets blog post about his previous Java/C# mailing lists examples - I did not catch any names, though I did they would be of benefit to me, if I had access to any of them.

• Why is Reflector such an essential utility?

  - by c152driver

  Reading the brouhaha surrounding Reflector going paid got me thinking about the product and its uses. Many people seem to consider it an essential tool. I have to admit, I haven't used Reflector in years. I mean, there's documentation for both the .Net APIs and the third party components I use. In the past, whenever a colleague pulled Reflector out of his tool belt, I got the sense he was headed into the weeds. Reading all the passion around Reflector is leading me to question if I'm really missing something here. Why do you need something like Reflector so often that you consider it an essential tool? I can see it being needed on very rare occasions, but not enough to be considered an essential tool. Please enlighten me.

• What's shell script's advantage over interpreted programming languages?

  - by Lai Yu-Hsuan

  (I'm not sure if it's a appropriate question here) Shell script, like bash, can do many things. It can call Unix programs, pipe their output, redirect I/O from/to files, control flow, check whether a file exists, etc. But a modern programming language, e.g, python and ruby, can also do these all. And their are (I think) more readable and maintainable. bash is worldwide spreaded. But many distributions have installed python interpreter, too. So what's the advantage of shell script? If I could write python, ruby or perl, is it worth to learn bash?

• Wireless speed drops over time and doesn't get up if not reconnected

  - by Vili Lehto

  I am using Ubuntu 12.10 64bit and I have a Asus PCE-N15 wireless card(in PCI-E slot). The problem is that first when I connect to my WiFi network the speed is just fine, and actually my link speed never drops, it shows a solid 150mb/s+ link speed and good signal. But the download and upload speeds drop dramatically after couple minutes of use and I have to reconnect to fix this. Network is type IEEE 802.11bgn and uses WPA2/AES encryption. I don't have similar problems on the windows side, and the network is working fine on every other device. iwconfig shows this: wlan0 IEEE 802.11bgn ESSID:"WLAN-AP" Mode:Managed Frequency:2.412 GHz Access Point: 00:1E:AB:05:EF:31 Bit Rate=300 Mb/s Tx-Power=20 dBm Retry long limit:7 RTS thr=2347 B Fragment thr:off Encryption key:off Power Management:off Link Quality=61/70 Signal level=-49 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:2 Missed beacon:0 So the question is: Is there a way to fix this? Thanks in advance.

• Canonical links for huge websites

  - by Florin

  Let's say I have 5 products that are identical but the product code, the product color specifications and the product image. The title, meta and description are identical (by the way the color is in a select form). I made 4 products link canonical to the 1 that is the master based on many factors. If the master becomes inactive or without a stock one product from the other 4 will become the new master and the rest will become canonical to it. The question is if that by becomeing master from canonical will the site suffer a penalty from Google or it will work just fine? What will Google think about this strategy?

• 302 Moved Temporarily or 301?

  - by user11221

  I have a question on redirects. HTTP status code checker tool shows "HTTP/1.1 302 Moved Temporarily" for the home page url http://someurl.com (just a namesake url). Also, this url opens up http://www.someurl.com/general/index. As you can see, a non-www url to a www url redirect is happening. My questions are: Is a 302 redirect acceptable for the home page? Will this affect the site showing up in search results in anyway? Isnt redirection to /general/index a bad practice?

• Multiple Vertex Buffers per Mesh

  - by Daniel

  I've run into the situation where the size of my mesh with all its vertices and indices, is larger than the (optimal) vertex buffer object upper limit (~8MB). I was wondering if I can sub-divide the mesh across multiple vertex buffers, and somehow retain validity of the indices. Ie a triangle with a indice at the first vertex, and an indice at the last (ie in seperate VBOs). All the while maintaining this within Vertex Array Objects. My thoughts are, save myself the hassle, and for meshes (messes :P) such as this, just use the necessary size ( 8MB); which is what I do at the moment. But ideally my buffer manager (wip) at the moment is using optimal sizes; I may just have to make a special case then... Any ideas? If necessary, a simple C++ code example is appreciated. Note: I have also cross-posted this on stackoverflow, as I was not sure as to which it would be more suitable (its partly a design question).

• How do I customize the Unity launcher for different workspaces?

  - by Srijan

  How do I customize the Unity launcher for different workspaces for Ubuntu 12.04? I am using x86-64 bit architecture running solely Ubuntu 12.04. I have searched in the community for possible aspects of this question as per the link Different Launchers for Different Workspaces? but the links provided in this doesn't address my issue as the links are outdated and it does not exactly say how to customize the launcher. Besides the environment is now buzzing with unity 5.4 and also Ubuntu 12.10. So can someone please help me to customize the unity launcher for Ubuntu 12.04 for different workspaces? Thanks a zillion in advance. Is there any features enabling customization of launcher in different workspaces in unity 5.4?

• What is this chargeback scam from eBooks bought on my website?

  - by Dan Friedman

  We have a scammer that is buying our e-Books and then performing chargebacks. Our e-Books don't have DRM, so if they wanted to resell them, they would only need to buy each book once. But instead, they keep buying the same books over and over again and then performing hundreds of chargebacks. We have created some additional rules in our fraud protection tools to block certain aspects, even though all the info looks legit, and are hopeful this will slow them down. But my question is: What is the scam? If they aren't getting any product and they only get chargebacks for something they already purchased, then they can't get additional money from the credit card company, so then what's their motivation?

• Didn't do too well on a Java IKM test, advice?

  - by Jason

  I did an IKM Java test recently and got quite a low score. I only graduated a year ago and I dont have commercial experience in Java (i do web development in my current job). I thought reading up a lot on Java would help me prepare, but when I sat the IKM test i got ripped to pieces. I didn't know much about how the garbage collection actually works, names of other java compilers (i know about javac?), using .dll with Java etc etc. I know a wide range of the basics, but to the extent wether 'int(5L)' produces an integer or not, I really didnt know. My question is that many of the IKM questions I have never come across, yet I have read many of the wider-known Java programming books (Deitel, O'Reilly etc). Am i reading the wrong books??? Could anyone recommend a good plan of action to allow me to go away and self-study and be able to know these really tough java questions?

• Hidden Loading with UDK

  - by CyrusFiredawn

  I was wondering, how would I go about creating hidden loading scenes with UDK? For example, a character walks in to an elevator, the elevator fakes movement, whilst the previous floor is destroyed and the next floor is loaded on top. I assume it's possible with UDK, since it's supposedly rather flexible, but I've never used UDK before (I decided to ask this question first to save me learning it all, finding out it isn't possible, then giving up). So yeah, is hiding the loading process possible? And if so, how would I go about doing it?

• Creating a bootable USB recovery drive to be used by someone who isn't computer savvy

  - by David

  I am looking for a way to prepare an image of an Ubuntu machine which would be bootable and installable in the easiest way possible. I'm actually preparing an Ubuntu machine for someone living far, and not computer savvy. If he ever has troubles with his installation, he could just put a USB drive in, boot the machine and everything would be resetted for him. I know there are many methods of creating/loading an image of a drive, but the ones I've found so far have complicated menus with several options to choose from, etc. Ideally, perhaps only asking a Yes/No question such as "Would you like to reinstall?" would be great. Does such a tool exist? Thank you in advance!

• sudo & redirect output

  - by Khaled

  I have a small question regarding using sudo with output redirect >. To enable IP forwrding, someone can use the command: $ echo 1 > /proc/sys/net/ipv4/ip_forward Executing this command will give permission denied as it requires root privileges. However, executing the same command with sudo gives also permission denied error! It seems that output redirect > does not inherit the permissions of the preceding command echo. Is this right? As a workaround I do: $ echo 1 | sudo tee /proc/sys/net/ipv4/ip_forward Is this the best way to do it? Am I missing something? Please, note that this is an example and it applies to all commands that use output redirect.

• Trying not to get ahead of myself but it is hard!

  - by Andrew

  Well I made a 5 year plan for myself (11years-16years) I am pretty good at Java, HTML, and PHP. I have already done some end projects: Small Java Platform Game A Small Polynomial Solver A Small Image Sharing Site A Chess Website: chesslounge.net I am currently doing some Android Development and so far I have made a program that Vibrates, Blinks the Light, or Creates a custom status message based on the user input. And a program that rotates a pyramid with a texture. My question is: Should I stick to what I am doing or Learn something a little new? I am itching to do C++, but what is your advice?

• Estimated budget for RockBand 3 character creator feature [closed]

  - by milesmeow

  I want to get an idea of the budget required to make something akin to the Rock Band 3 character creator. We won't have the same level of detail for creating the base character, i.e. no face feature customization. We essentially want some very basic body sizing and want a bunch of clothing and accessories that the characters can try on. The clothing and accessories need to adapt and fit to the body types/shapes. The character should also support movement...and the clothes should move with the body. I've asked a similar question here regarding the development effort but not necessarily a budget. Do you think it's a $1M job? Most of the effort will go into creating the character models and the clothing models. The rest of the effort will go towards the user interface to navigate the customization features.

• C: What is a good source to teach standard/basic code conventions to someone newly learning the language ?

  - by shan23

  I'm tutoring someone who can be described as a rank newcomer in C. Understandably, she does not know much about coding conventions generally practiced, and hence all her programs tend to use single letter vars, mismatched spacing/indentation and the like, making it very difficult to read/debug her endeavors. My question is, is there a link/set of guidelines and examples which she can use for adopting basic code conventions ? It should not be too arcane as to scare her off, yet inclusive enough to have the basics covered (so that no one woulc wince looking at the code). Any suggestions ?

• can't download music files purchased with ubuntu one from rhythmbox

  - by Andrea

  I used the link to Ubuntu One in Rhythmbox music player to purchase music. On the My Downloads page from Ubuntu One in the Rhythmbox it shows each of the files I purchased with and mp3 button and an AAC button. I should be able to download the files from these buttons but when I click on the button nothing happens - I was expecting a download manager to open up. I also was expecting the files to be transferred to my UbuntuOne account but don't see anything there either. (this is probably a second question) I am using 12.04 beta version of Ubuntu and the version of Rhythmbox that came with it: 2.96. Do I need to install something to be able to download these links? Thanks.

• How would you represent an object that can be of multiple types, when storing it as a document in MongoDB?

  - by blueberryfields

  Somewhat related to this question, say that I have an object category which, depending on which type of object I have, has different restrictions on what it contains. (if you can reword the previous sentence to make more sense I'd appreciate it) For example var SomeSchema = new Schema({ _id: ObjectID, [... large number of common fields ...] type: //Restricted somehow to members of a fixed array data: //depending on type, this might be restricted - sometimes an integer, sometimes array, etc... }); What's the idiosyncratic method for defining this type of schema? Is it appropriate to define a single schema, and handle the types inside of it's members, or am I better off with separate schema for each type?
