• hexdump confusion

  - by zedoo

  I am playing with the unix hexdump utility. My input file is UTF-8 encoded, containing a single character ñ, which is C3 B1 in hexadecimal UTF-8. hexdump test.txt 0000000 b1c3 0000002 Huh? This shows B1 C3 - the inverse of what I expected! Can someone explain? For getting the expected output I do: hexdump -C test.txt 00000000 c3 b1 |..| 00000002 I was thinking I understand encoding systems..

• Random record in ActiveRecord

  - by astrofoo

  I'm in need of getting a random record from a table via ActiveRecord. I've followed the example from Jamis Buck from 2006. However, I've also come across another way via a Google search (can't attribute with a link due to new user restrictions): rand_id = rand(Model.count) rand_record = Model.first(:conditions => [ "id >= ?", rand_id]) I'm curious how others on here have done it or if anyone knows what way would be more efficient.

  - by calico-cat

  I've done consulting work for years and I've got code snippets in various languages lying around that I'll re-use for various projects. The collection is getting pretty large and I want to set up a code bank for myself. What code banks do people use? Do you find it helps, or is there some better way of organising my reusable code snippets? (If one does exist, I'd prefer it be open-source, accessible via a web browser, language-agnostic, and maybe colour the code the way Stackoverflow does :)

  Hi, I think i'm getting senile because I was convinced that to give a name to your application, you had to fill this part of the manifest : <application android:icon="@drawable/icon" android:label="MyApplicationName"> However for a reason I don't understand, my application gets the name of my first activity, in which I load data, henceforce, It is called "Loading"...(defined as follows in the manifest) <activity android:name="AccueilSplash" android:label="Loading"> Any idea why that is?

Management is completely disengaged, and the users as well. What do you do in this type of situation? I've taken to learning some deeper aspects of .Net and software construction in general, but don't like the feeling that I'm stiffing my employer.
