• What are the reasons *not* to use a GUID for a primary key?

  - by Yarin

  Whenever I design a database I automatically start with an auto-generating GUID primary key for each of my tables (excepting look-up tables) I know I'll never lose sleep over duplicate keys, merging tables, etc. To me it just makes sense philosophically that any given record should be unique across all domains, and that that uniqueness should be represented in a consistent way from table to table. I realize it will never be the most performant option, but putting performance aside, I'd like to know if there are philosophical arguments against this practice?

• How does Android emulator performance compare to real device performance?

  - by uj2

  I'm looking into writing an Android game, tough I don't curerntly own an Android device. For those of you who own a device, how does the performance on the emulator relate to real device performance? I'm especially interested in graphics related tasks. This obviously depends on both the machine running the emulator, and the specific device in question, but I'm talking rough numbers here. This question is a duplicate, but since that post is heavily outdated, I figured it's irrelevant by now.

• How to write a lightroom plugin which sets the crop of all selected images?

  - by Sam

  I wonder if it is possible to write a lightroom plugin, which applies crop rectangles to a set of images? Of course I do not just want to duplicate the crop, I'd like to set a different crop to every image, based on some computations. Can this be achieved with lightroom plugins, or would I need to try a different approach?

• JavaScript find box

  - by cf_PhillipSenn

  I'd like to duplicate the find feature (Ctrl-F in Firefox) for my users. In other words, a text box that as the user types, it finds the first occurrence of that text, and if they press "Next", it highlights the next occurrence and moves the page if necessary. I'm thinking the search input would have to be in a div that remained fixed, and as it found what it was looking for, would insert a named anchor just before it and then follow the hyperlink. Do you think this can be done?

• get pure text form odt file in console

  - by naugtur

  I am looking for a small linux tool that would be able to extract text from odt file. It just needs to be human-readable and it can have problems with complicated objects etc. It's almost a duplicate of this question but I need it to be small and have no dependencies on OpenOffice or X server I remember having a 1MB MS-DOS program that could render .doc files quite readibly (with some weird markup getting through from time to time), so i expect it to be possible in the linux world too ;)
