  • Table in DB for generating primary keys?

    - by Sapphire
    Do you ever use a separate table for "generating" artificial primary keys for DB (and why)? What I mean is to have a table with two columns, table name and current ID - with which you could get new "ID" for some table by simply locking the row with that table name, getting the current value of the key, increment it by one, and unlock the row. Why would you prefer this over standard integer identity column? P.S. The "idea" is from Fowlers Patterns of Enterprise Application Architecture, btw...

  • Is two-finger non-homerow touch-typing for programming acceptable?

    - by codebliss
    I'm currently typing about 90 wpm (from http://speedtest.10-fast-fingers.com/ 90 correct 0 missed) using two fingers and the occasional ring or index. This probably grew from learning to type at an early age, before home-row was presented to me. Is this acceptable? Do people religiously endorse home-row even with low-mistake poking without looking at the keyboard?

  • What does this mean in AS3?

    - by uther-lightbringer
    Hello I've started to learning AS3 from one book and found something I don't understand. Ellipse(_board[row][column]).fill = getFill(row, column); _board is two dimensional array of Ellipse type, so I just dont understand why is Ellipse(Ellipse object) used when it apparently works without it, or I haven't seen any changes when I omitted it.

  • binlog_format = STATEMENT and CURRENT_TIMESTAMP with MySQL replication

    - by xma
    Hi, can a MySQL slave instance have different row values for the same ID when binlog_format is set to STATEMENT and we insert something like: insert into foo values(CURRENT_TIMESTAMP) As I understand it, the slave read the SQL statement and execute it thus, if the replication is lagging, could lead to differences for the same row. Right or wrong ? How can I avoid this situation ? Thank you.

    - by SWKK
    Hi Guys, a bit of a naive question, but nonetheless. I am trying to break up a for loop in which a 2d Matrix is being read. I would like to write a callback function to consume row-wise/col-wise chunks per row/col iteration. Any hints on how to tie up the callback function with iteration?

  • Converting Numpy Lstsq residual value to R^2

    - by whatnick
    I am performing a least squares regression as below (univariate). I would like to express the significance of the result in terms of R^2. Numpy returns a value of unscaled residual, what would be a sensible way of normalizing this. field_clean,back_clean = rid_zeros(backscatter,field_data) num_vals = len(field_clean) x = field_clean[:,row:row+1] y = 10*log10(back_clean) A = hstack([x, ones((num_vals,1))]) soln = lstsq(A, y ) m, c = soln [0] residues = soln [1] print residues
