• What implementation problems are still soaking up all of your time?

  - by Conor

  What implementation problems has the industry claimed to have solved many times, but are still soaking up all of your time? Examples: Cross platform GUI - mobile devices have blown this issue wide open. OO to RDBMS mapping - how do I map this attribute to that field in that database using that framework. You get the idea. Interface definitions - ..., CORBA, COM, EJB, WSDL, ..., etc Can you think of any others?

• Semantic algorithms

  - by Mythago

  I have a more theoretical than practical question. I'll start with an example - when I get an email and open it on my iPad, there is a feature, which recognizes the timestamp from the text and offers me to create an event in the calendar. Simply told, I want to know theoretically how it's done - I believe it's some kind of semantic parsing, and I would like if someone could point me to some resources, where I can read more about this.

• Strategy for avoiding duplicate object ids for data shared across devices using iCloud

  - by rmaddy

  I have a data intensive iOS app that is not using CoreData nor does it support iCloud synching (yet). All of my objects are created with unique keys. I use a simple long long initialized with the current time. Then as I need a new key I increment the value by 1. This has all worked well for a few years with the app running isolated on a single device. Now I want to add support for automatic data sync across devices using iCloud. As my app is written, there is the possibility that two objects created on two different devices could end up with the same key. I need to avoid this possibility. I'm looking for ideas for solving this issue. I have a few requirements that the solution must meet: 1) The key needs to remain a single integral data type. Converting all existing keys to a compound key or to a string or other type would affect the entire code base and likely result in more bugs than it's worth. 2) The solution can't depend on an Internet connection. A user must be able to run the app and add data even with no Internet connection. The data should still resolve properly later when the data syncs through iCloud once a connection is available. I'll accept one exception to this rule. If no other option is available, I may be open to requiring an Internet connection the first time the app's data is initialized. One idea I have been toying around with in my head is logically splitting the integer key into two parts. The high 4 or 5 bits could be used as some sort of device id while the rest represents the actual key. The fuzzy part is figuring out how to come up with non-conflicting device ids that fit in a few bits. This should be viable since I don't need to deal will millions of devices. I just need to deal with the few devices that would be shared by a given iCloud account. I'm open to suggestions. Thanks.

• Way(s) of browsing the filesystem that are more flexible

  - by ixtmixilix

  I have two related questions, both probably (but not necessarily preferentially) accepting the same answer : When browsing or exploring the filesystem in a GUI, I want to be able to right click on the empty space between the files, choose a menu item and say 'open terminal in this folder,' optionally as root Do the converse when using the terminal, optionally as root I use Universe with kubuntu but have Debian Lenny running with gnome installed separately, so anything on kde or gnome would work

• How to drag widgets from monitor to monitor in kubuntu?

  - by Mien

  I have Kubuntu 12.04 on my Dell Inspiron. I use an extern monitor as my default one, and my laptop monitor as my second monitor. I can place widgets on the extern (default) screen, but when I drag them to the laptop (second) screen, they disappear. I can put widgets on the second screen, if I open the widget screen on that screen, but I can't drag them to my first monitor. How can I switch between monitors for the widgets?

• Is there a jQuery lightbox plugin that has thumbnails inside the box?

  - by Gabriel

  I'm trying to find a lightbox style plugin in jQuery that displays thumbnails at the bottom of the picture (or video, or whatever). I found plenty of lightbox plugins, but none that allows navigation by thumbnail inside the box. The plugin must be able to open images, swf and inline content. I realize that jQuery will not be able to generate the thumbnails and that's ok. Do you have any good ones to suggest? Thanks

• If you had to teach professional development to students that just graduated school, what would be the topics?

  - by user2567

  The idea is to give them more chances to be efficient in a professional environment. Most students are good with theory, most of them are smart, but they have to learn how to solve common technical problems. They will be better programmers as they practice, but maybe we can help them with some introduction training. Which topics you would select for a two weeks full time training? It's an open question, I don't want to suggest things that will reduce the answers to a particular field.

• Why DbContext object shouldn't be referred in Service Layer?

  - by nazmoonnoor

  I've been looking for some implementations of Service Layer and Controller interaction in blogs and in some open source projects. All of them seem to refer DbContext object in repository classes but avoided to use in service classes. Service classes essentially using a IQueryable<T> references of DbSet<T>. I want to know why this practice is good and why DbContext shouldn't have a reference in Service Layer.

• Attending my first software conference - any tips before I go? [closed]

  - by Paul Weber

  My nice employer allowed me to visit a software conference in June (International PHP Conference, for those who care). Wanting to make the most of it, I would ask the more experienced conference goers in here to give me some tips on what I could do to maximize my learning experience on the conference, and to reduce beginner mistakes. Sorry that this question is a little ambiguous, but I think it's best to keep it a little bit more open, so I can get a wide range of Ideas, and it will be of more use to further people seeking for an answer.
