    - by f.mcleash

Now I am only using the keyboard shortcuts to use Ubuntu. My graphic card is AMD ATI. What can I do to bring the menus back?

  • How to make my newly created secondary partition accessible?

    - by cipricus
    I have decided to reinstall my Lubuntu OS and to split on the occasion my partition so as to have a secondary one where long-time files would be stored. When trying to install the system onto the smaller one, I was prompted to set a different mount point for the other (different from /). Not knowing what to do I selected /boot for the second and went on installing on the first one. All was ok except that now the larger/secondary (/boot mount point) partition is not visible. In Gparted it is:

  • Is it good practice to keep 2 related tables (using auto_increment PK) to have the same Max of auto_increment ID when table1 got modified?

    - by Tum
    This question is about good design practice in programming. Let see this example, we have 2 interrelated tables: Table1 textID - text 1 - love.. 2 - men... ... Table2 rID - textID 1 - 1 2 - 2 ... Note: In Table1: textID is auto_increment primary key In Table2: rID is auto_increment primary key & textID is foreign key The relationship is that 1 rID will have 1 and only 1 textID but 1 textID can have a few rID. So, when table1 got modification then table2 should be updated accordingly. Ok, here is a fictitious example. You build a very complicated system. When you modify 1 record in table1, you need to keep track of the related record in table2. To keep track, you can do like this: Option 1: When you modify a record in table1, you will try to modify a related record in table 2. This could be quite hard in term of programming expecially for a very very complicated system. Option 2: instead of modifying a related record in table2, you decided to delete old record in table 2 & insert new one. This is easier for you to program. For example, suppose you are using option2, then when you modify record 1,2,3,....,100 in table1, the table2 will look like this: Table2 rID - textID 101 - 1 102 - 2 ... 200 - 100 This means the Max of auto_increment IDs in table1 is still the same (100) but the Max of auto_increment IDs in table2 already reached 200. what if the user modify many times? if they do then the table2 may run out of records? we can use BigInt but that make the app run slower? Note: If you spend time to program to modify records in table2 when table1 got modified then it will be very hard & thus it will be error prone. But if you just clear the old record & insert new records into table2 then it is much easy to program & thus your program is simpler & less error prone. So, is it good practice to keep 2 related tables (using auto_increment PK) to have the same Max of auto_increment ID when table1 got modified?

  • How to tell two windows of the same program apart? [closed]

    - by john mossel
    Possible Duplicate: Disable joining multiple windows to one icon in unity panel If I have two vlc players open, I have to go to the sidebar and click on the vlc icon, then pick which one I want (it does this cool effect where it shows you both windows side by side-- as great as that is, it gets bloody annoying after a while). Is there not an easier way of doing this? Is there no possibility of reverting back to the old system?

  • Clean install with home folder and multiple users

    - by haydoni
    I had reformatted my system (unfortunately an update failed) and had my home folder on a separate partition. Thankfully I still have all of my users files (in their respective folders), but there was no option to use this on install (since my update had failed...). How can I recreate the old users with their previous home directories? (Are there problems with user permissions with just dragging and dropping the entire contents of folders?)
