• Are there advantages of using hard coded URLs for localization?

  - by nbolton

  On the Synergy website, localization is detected (and can be overridden) but uses the same URL for all languages. Some websites however, like Wikipedia have language specific subdomains. What are the advantages of having either subdomains or subdirectories (i.e. a specific URL) for each language localization? Also, should it automatically redirect the user to the specific subdomain/subdir based on the language that the browser requests? I suspect that there are advantages, which I'm guessing are: When the website appears in search results for non-English languages, the translated page description will be shown (assuming there is a translation provided by the website). When a user shares a page (e.g. through twitter), it will show in a specific language. Perhaps this is a disadvantage though? Am I correct, if so, are there more advantages?

• Domain Model and Querying

  - by Tyrsius

  I am new to DDD, having worked only in Transaction-Script apps with an anemic model, or just Big Balls of Mud, so please forgive any terminology I abuse. I am trying to understand the proper separation between the domain model and the repository. What is the proper way to construct a domain object that is coming from a database, assuming the (incredibly simplified) need to query for objects by status (returns enumerable), or by ID. Should a factory be building the objects, exposing methods for GetByStatus() and GetByID(), using a DIed repository? Should a repository be called directly, knowing how to build a domain model from the DTO? Should the domain model have a constructor for get by ID, using a DIed repoistory to load the initial state, using some other (?) method for the list? I am not really sure what the best way would be, and this question has an answer advocating each one (these are certainly mutuallu exclusive).

• Emacs-like keybindings system-wide?

  - by kermit666

  Is there a way to set Emacs-like keyboard shortcuts (at least the subset mentioned below) for the whole OS? This is possible in some apps such as the terminal, Emacs (go figure :) and additionally through special plugins in some other apps (Eclipse), but I got so used to C-f-ing through text and never having to jump to arrows that I'd like to be able to do this system-wide so that I can do it whenever I'm typing - e.g. searching for songs in Rhythmbox, typing stuff into the dash or the HUD, writing mails in Thunderbird or Gmail... The combos I'm most interested in are: C-f - forward C-b - backwards C-a - home C-e - end C-d - delete C-k - delete line (note for non-emacs users - C means Ctrl)

• Issues with HP Mini 110-1125NR

  - by Guga Figueiredo

  Just finished installing Ubuntu 12.04 Precise Pangolin on my HP Mini 110-1125NR and im having small, but rather irritating issues. I installed it over the Windows 7 (starter) which came with the netbook. Firstly, it will only boot from the USB flashdisk. If i try to boot from the hardrive, it goes to a black screen. Second, built-in wireless wont activate. system says its enabled and on, but the light indicator is still orange (as if its off), and i cant get a signal from my home wi-fi I havent found any solved threads for inspiration, and mos of them are pretty old (1 year +) so i thought of giving a try to see if any of you guys System is: HP Mini 110-1100 1gb memory Intel Atom CPU N270 @ 1.60GHz x 2 Os - Precise Pangolin - Ubuntu 12.04 160gb Hard disk If any of you are aware of the solutions of my issues it'd be awesome Thanks in advance for any help!

• Ubuntu user expectations from 12.04 and future releases

  - by Rick Green - Turbo

  How much further ahead is 12.10 vs 12.04 in respect to kernel updates and applications? Example: Gimp's newest release is 2.8 which runs equally as well in both 12.04 and 12.10 and probably will in 13.04. What restricts 12.04 from having "the same" look, feel, applications and kernel as 12.10 or the upcoming 13.04? I know that it's more than a name change.....it's whats under the hood that counts. Incrementally upgrading, I feel is safer than radical changes from release to release. Trying to keep a stable desktop and current user experience, how far can I take updating applications before I absolutely have to make a distro upgrade from 12.04LTS

• Wi-Fi connections gets Idle

  - by marcocamejo

  I am having this terrible problem. I have read a lot of people getting disconnected from the Network, it is not my case, I don't get disconnected, the connection just gets "idle" most of the time. It only works for short periods of time (seconds, a couple of minutes at most), then gets dead, then works again, and so on. It is annoying. I am using Ubuntu 11.10 on a Dell M5030 laptop. I have Windows 7 installed too, and of course with it, the wifi works perfectly. Any idea? advice?

• Writing the tests for FluentPath

  Writing the tests for FluentPath is a challenge. The library is a wrapper around a legacy API (System.IO) that wasnt designed to be easily testable. If it were more testable, the sensible testing methodology would be to tell System.IO to act against a mock file system, which would enable me to verify that my code is doing the expected file system operations without having to manipulate the actual, physical file system: what we are testing here is FluentPath, not System.IO. Unfortunately, that...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight.

• Java EE/GlassFish@Java2Days

  - by reza_rahman

  Java2Days 2012 was held in Sofia, Bulgaria on October 25-26. This was the third installment of the premier Java conference for the Balkan region, having three separate tracks for Java, the Cloud and Mobile. It attracted over a thousand enthusiastic, bright young developers and a number of world class speakers. There were no less than three full-house sessions on Java EE/GlassFish - one on Java EE 7, one on Domain-Driven Design using Java EE 6 and one on JSR 356/WebSocket. More details on Java EE/GlassFish@Java2Days, including slides and code examples, posted here.

• Yet another Java EE 6 book

  - by alexismp

  We have a new Java EE 6 book in store! This one from Packt Publishing is called "Java EE 6 Development with NetBeans 7" by David Heffelfinger who is also author of Java EE 5 and GlassFish books. This book holds a step-by-step book documention all of the Java EE 6 features and APIs (including CDI) using the IDE with the best Java EE out-of-the-box experience : NetBeans 7. It uses GlassFish as the default container and PrimeFaces as a JSF component suite. We've covered several Java EE and GlassFish books before and I can't help but think that given writing books never helped authors retire early, having so many good books on Java EE 6 says something about its success among developers.

• When do I bite the bullet and hire a developer? [closed]

  - by Paul Seattle

  I have an awesome URL, I've had it since the mid 90's, and up until around 2002 I was having an awesome time writing music reviews and features into static pages and adding their URL to static index pages and everything was just great. Then things got complicated really fast, and for one reason or another I handed the site over to a very talented friend who turned it into a db based site run by cf. Now, here I am around twelve years later putting it all back together using mysql, php and css on a need-to-learn basis and even though I'm sooo close to where I want it to be I realize, erm, it should have been written using mysqli etc etc ad infinitum. So I'm wondering at what point do I just give in and hire a developer to take over, how much does it even cost, and how do I know I'm working with someone who is better than I am?

• Ubuntu One slow download sync speed

  - by Ian M

  I am having problems syncing my Ubuntu One files with my Ubuntu 12.04 fresh installation. Everything went well during the setup phase. Now, I am trying to sync back in my folders in my U1 account and the transfer speed is extremely slow. I am averaging a 15kb/s transfer speed. I tried uninstalling ubuntuone-client and reinstalling it. It did not fixed the problem. Right now U1 is stuck downloading a 50mb file. It is taking forever. Any ideas?

• Algorithm to generate N random numbers between A and B which sum up to X

  - by Shaamaan

  This problem seemed like something which should be solvable with but a few lines of code. Unfortunately, once I actually started to write the thing, I've realized it's not as simple as it sounds. What I need is a set of X random numbers, each of which is between A and B and they all add up to X. The exact variables for the problem I'm facing seem to be even simpler: I need 5 numbers, between -1 and 1 (note: these are decimal numbers), which add up to 1. My initial "few lines of code, should be easy" approach was to randomize 4 numbers between -1 and 1 (which is simple enough), and then make the last one 1-(sum of previous numbers). This quickly proved wrong, as the last number could just as well be larger than 1 or smaller than -1. What would be the best way to approach this problem? PS. Just for reference: I'm using C#, but I don't think it matters. I'm actually having trouble creating a good enough solution for the problem in my head.

• What to do about unreadable grub screen

  - by stevecoh1

  I have been upgrading my Ubuntu, from 10.04 to 12.04 to 12.10 to 13.04 in the past few days with varying degrees of success. One problem that has been constant through every step of the upgrade, since 12.04 is that a portion of the text on the grub screen is off the screen to the left so I can't completely make out what the options are. As I am having other troubles with the upgrade I would like to at least be able to see what options there are to me at boot time. Is there some sort of grub configuration that can handle this?

• Data structure supporting the following operations

  - by 500865

  I'm looking for a data structure for working with a set of data which is most efficient to do the following : Check whether an item has been categorized or not. (The categorized and uncategorized set are disjoint sets). Get the category of an item. Get all the items in a particular category. Get all the uncategorized items. Remove a particular item from the data set. I was thinking of having a Dictionary<String, Set<String>> to hold all the items in a given category, but that doesn't solve 2.

• confusion understanding the fluid 2 column navigation layout

  - by Jason Madux

  I'm trying to understand the following cross-browser layout: http://matthewjamestaylor.com/blog/perfect-2-column-left-menu.htm but I'm having some confusion with some of its parts and there isn't enough information on the page or in the css comments to help me. What is the purpose of the .colleft div? Why can't the 2 columns be directly under the .colmask container? Why does the .colleft div have a right 75%? I don't understand its purpose/benefit. Why don't the widths of .col1 and .col2 add up to 100%? How was left:102% calculated for .col1 and left:6% for .col2? The comments for this are not very clear to me. How is it any different from not even specifiying a left/right css property?

• Which is the best low/mid level GPU in terms of compatibility for 12.04 and 12.10?

  - by Ghost

  I'm tired of dealing with the disaster that is catalyst on a 4xxx IGP and I want to buy some discrete graphics that support both Unity and alternative environments like GNOME3 and Mate-Cinnamon without getting sluggish. Besides that, 1080p video and some light 3D gaming. Again nothing crazy, I'm not a designer and I wont be using stuff like Blender. One thing I want to make clear is that I want a GPU that is 100% compatible, that means no bugs, no glitches, not having to toggle between propietary and Xorg because it decided to crapout on me. Thanks for your help

• How to install Ubuntu on PC with no detected OS?

  - by brad54322

  I have a Spanish OS based on 11.04 called 'Darwin OS'. After installing it, the setup file still existed on the desktop. So, I opened it to see what would happen. It got stuck at Detecting file systems so I just closed it. Later, I started having a lot of problems with the OS so I decided to switch to the normal 12.04. But when I booted from my USB, it said An Operating System wasn't found. Try disconnecting any drives that don't contain an Operating system. Press Ctrl-Alt-Del to restart. I tried that a couple of times but nothing happened. What should I do?

• GlassFish Community Event @ JavaOne - Save the date!

  - by alexismp

  The interest for having a GlassFish community event at JavaOne is still very strong both inside Oracle and in the community, so this year again we'll be hosting a get together on the Sunday prior to the main event. If you're in town and attending JavaOne, mark your calendars : Sunday 2nd, October 2011 - 12:30pm-4:30pm in the Moscone This will be an opportunity to discuss the community status (adoption of Java EE 6, GlassFish 3.1.x) and hear about future plans, mainly around Java EE 7 and the related GlassFish release(s). We'd also like to have several participants share their deployment stories as well as some time for an free-form unconference format and some team building activity. Of course, beyond all the content shared in slides, this should really also be a good excuse to meet folks from the community and from the core GlassFish team at Oracle. Here's a post on last year's event. And before anybody asks, we are still exploring the party situation :-)

• Moving from an IT department to a proper technology company

  - by user2434

  I have been working with Java/web applications in an IT department of a retail company. As much as work goes, there is nothing much to say. Fixing couple of if/else loops, writing some simple business logic etc., is all what I have been doing. Having said that, I feel I have a good technical knowledge, and I am willing to move to companies like Microsoft/Google/Amazon etc., [I want to work in these places, because I feel I am a technical guy, and I am working in a place where most people freak out when the words like 'algorithm' are heard] I can of course prepare algorithms/computer science fundamentals etc.,(I hold a 4 year degree in computer science program) but beyond that, will my experience hold against me ? I doubt I'll even get a call from them seeing my work experience. What kind of questions(apart from the algorithm types) can I expect ?

• kernel panic - diagnosis?

  - by user94188

  I'm having a kernel panic problem - my machine will run for hours, maybe all day and then have a panic attack. I have no idea how to interpret the output, but here's a picture of what's left on the screen when it happens: https://dl.dropbox.com/u/13279067/photo.JPG (I can't post images yet) I've looked through the logs but didn't find anything obvious - I'm still learning though so I've probably missed something. It's a little harder since it's always happened when I've been out or at night so I can't pinpoint the exact time it crashed. Anyone have advice? thanks

• How to properly shield a Product Owner from outside?

  - by xsAce

  Update: We are a very small team (3 people) and thus I (Scrum Master) and the Product Owner are also developers doing some coding. We are aware of this situation and we are actively trying to recruit some new talents. But it's hard! Meanwhile... we need to adapt... so my question: The Product Owner complains about having too much outside noise (mainly stakeholders feature requests), and he can't focus on the sprint realisation. We agree that we should try to educate people on our process implications (sprint durations and product backlog), to reduce the noise. But as a Scrum Master, how am I supposed to shield a PO from outside? Isn't he supposed to be in contact with the management and business? Also, if people outside don't want to waste too much time learning agile, what is the best way to educate them?

• Can it be a good idea to create a new table for each client of a webapp?

  - by Will

  This is semi-hypothetical, and as I've no experience in dealing with massive database tables, I have no idea if this is horrible for some reason. On to the situation: Imagine a web based application - lets say accounting software - which has 20,000 clients and each client has 1000+ entries in a table. That's 20 million rows which I know can certainly slow down complex queries. In a case like this, does it make more sense to create a new table in the database for each client? How do databases react to having 20k (or more!) tables?

• Photo sharing social platform [closed]

  - by user1696497

  I am working on a photo sharing social platform like Flickr, Photobucket. To start off with I have half a million photos as of now. I want to convert all of these into a single format, compression ratio and use it as an original image. I will be storing original image, re-sized image according to layout and a thumbnail. I have started off with ruby, didn't find supporting libraries. I am considering python as it has a good image processing library and instagram is using it. I want some advise about how the image has to be processed while uploading, efficient way of storage whether database or a file system, image compressions, and precautions to be taken. I would be having profile pictures, do I need store them separately or along with the images? If I want to store the images on a file system, which file system should I use and also should I store the url or should I use any intermediate key value store like redis?

• How do I duplicate a Box2d simulation, mid-simulation?

  - by Whyte

  I want to serialize the state mid-game, send it over the network to an identical computer (same CPU, same OS, same binary), load it there, and have the two games run in tandem doing the exact same simulation, without one of them drifting off and going haywire. In short: I want pop-in, pop-out networking support on my HIGHLY physics-intensive game, where sending object coordinates every few seconds is impossible, due to having thousands of objects, and many clients. I tried this with Box2D, and saving an object's location/velocity/etc wasn't enough... there's internal state that's not accessible through any public methods. My current workaround is to force EVERY client to save its entire worldstate and reload it from scratch, whenever a new player connects... but this is obviously bad practice, because it hangs the game for everyone whenever someone new connects. However, it works, with zero desynchronization. So, anyone know of any other techniques that can help me? Or should I just kiss my project goodbye?

• Internet Not Working... Initially Worked fine

  - by Sneha429

  I am using an HP Pavilion desktop, not sure of exact model, etc. Initially saucy looked and worked great. It's my parents, and after two days of no issues, they started having more than a few. The mostly use the internet to access email and videos. I believe Google Chrome was the only application they used. Then, the internet stopped working. Restarting didn't fix it, neither did turning the internet on and off. The computer went from lightening fast to inexplicably slow. I've read some other posts about the internet not working, but none seemed applicable. Any suggestions?
