Furthermore, I've tried to use @Column annotation: @Column(columnDefinition="TEXT") private String body; But everything in vain. I would be gratefull for a helpfull comment on this problem.

  • How to achieve vertical div alignment in unique situation?

    - by Earl Larson
    Go to my blog and please tell me how to achieve vertical alignment :( My situation truly is different and I need help :) The reason this is so difficult is because holder is the div that contains everything, outer are the icons at the bottom, and tooltip are the divs that pop up. I need tooltip to be vertically aligned but they are actually below outer. Each icon is connected to their post so you can't keep them all in one div.

  • What was the single byte change to port WordStar from CP/M to DOS?

    - by amarillion
    I was re-reading Joel's Strategy Letter II: Chicken and Egg problems and came across this fun quote: In fact, WordStar was ported to DOS by changing one single byte in the code. (Real Programmers can tell you what that byte was, I've long since forgotten). I couldn't find any other references to this with a quick Google search. Is this true or just a figure of speech? In the interest of my quest to become a "Real Programmer", what was the single byte change?
