A few quick hits.
You can merge the two for loops
You have not need one of the constants 1 and 2 in the index table. They will solve automatically when you expand on the index picture, once you have wired to 0 in the column index.
It seems a lot of handling additional table spent unnecessarily.
See below. I did not try to duplicate your code to see how it actually works, but I believe that I have attached will give the same result with less steps.

Classic scenario: after the bookmark long manual organization Firefox Sync adds trash of its server to my laptop or tablet.
Where can I find how to replace the content of the backup of the server by settings/passwords / current browser bookmarks? Stupid me, I put a new synchronization and lost this ability.
It is not recommended to go back to the old version of Sync
The old version is removed he'll stop being available soon, it takes getting used to using the new version.
IIRC, it is actually possible to force synchronization of the old working with Fx29 & Fx30 using an old profile or preferences of piracy, but I don't think I should encourage users to try this, but it would be better than using an older version of Firefox which is really bad. In fact using an old outdated version of Firefox is so bad, that it is customary to recommend using a browser on alternative day of someone else instead.
Firefox ESR is aimed at corporate users, definitely, at the moment, it will use the synchronization of the former. Who will update soon to use synchronization well again, and this time, I guess the synchronization of the former will probably totally frowned upon for example are not available at all.
It is possible to use the feedback system to leave a short comment on Sync. I would recommend this making, but at least to make very many people of spirit comments that I doubt will have no effect.

Satellite Pro L50 - a: how to replace the memory, HARD drive and battery
I just uploaded 2 new video from Youtube on the L50 - A. Satellite Pro
The first is a tear down showing how to replace the memory, hard drive and battery (you can also clean the fan if it detects overheating).
http://www.YouTube.com/watch?v=IG0lW7t92bI
BTW why they made it so difficult to get just to the battery in this model?
WARNING - proceed at your own risk and don't forget static precautions!
Hope they help and if you have any questions let me know.

Thanks for these videos. It may be useful to replace the memory, but I think that the owners of the laptop should not open the case. This may void the warranty.
Be careful about this. -

Hello
My laptop's dvd - rom drive is old and broken, now that I have here an other dvd - rom drive, but I don't know how to remove the old dvd - rom without removing all parts of my laptop. Is there some service manuals how to replace the dvd - rom drive?

For the most part the ODD is secured with the screw at the bottom of the unit.
You will need to remove this screw to get out and to swap the drive.But be careful and don t there if you have no experience!
Moreover, not all readers are compatible and supported in reason parameters master/slave/c-salt. If you n t know which drives are compatible you should ask the ASP in your country for advice! -

a.z.Hello
In various cases the ODD replacement is very delicate.
If you wish, you can consult this forum category.
Here you will find some videos how to replace the ODD on the different laptop models:
http://forums.computers.Toshiba-Europe.com/Forums/Forum.jspa?forumid=115This is also a nice Youtube Channel which provides the instructions how to replace the ODD:

How to replace the HDD on Satellite 1130?
How to replace the hard drive in this notebook?
Hello
If I remember well HDD is under the optical media drive. Optical media drive is fixed with a screw that you see above the player. Remove the screw and remove the drive from the Bay.
HARD drive is fixed, I think, 4 screws (probably black). When the screws are removed you can use two fingers to remove the HDD from the connector plug. I hope you now know how to put the new HARD drive.
Good bye

How to replace the screen & HDD in Tecra S1
Could someone help me with 2 queries?
1. how to replace the screen? I broke my screen 15 "and have a replacement original but would like to know if this is possible without the help of the reseller, etc.
2. bad drive c. message is 992 KB bad clusters. How to replace or repair the C drive?

BLHello
Well, the replacement of HARD disk drive is very easy on the Tecra S1.
At the bottom of the unit, you will find a cover that protects the HARD drive Bay.
A screw covers. Remove it.
Then, it should be possible to remove the HARD drive.The replacement of the screen is another matter. It is not easy to remove it. In this case I recommend to contact Toshiba service in your country for details.

Hello!
AFAIK, you must remove the keyboard first, before you can replace the CD/DVD drive. Remove the screws on the lower side, and then you can push the disc if you have replaced the keyboard.
It seems to be a bit trickyMaybe you should ask a technician for laptop to help. They can replace the CD/DVD drive for you.
Good bye

Equium - how to replace the HARD drive?
Hello
I need to replace the hard drive on my Toshiba Equium.
Can someone tell me the procedure? I changed it once before, and I remember having to press one of the function keys when I turned on the laptop with the new hard drive installed.
Should I have the recovery disk when the laptop is turned on with the new hard drive installed?Thank you very much
Tim.
Hey,.
You should take a look in your user manual. Sometimes you will find a detailed how instruction replace the HARD disk, but it according to your laptop model.
If you swapped the HARD drive, you need to reinstall Windows. Therefore, you can take the Toshiba Recovery disk that will restore the initial setup in a few minutes with all the drivers and tools. You only have to boot from that drive and that s all! :)

Satallite A100: How to replace the keys?
Is there a manual on how to replace the keys once they come out?
My Satallite A100, a year, lost two keys a few weeks ago, and I am unable to replace them, even if I have all the parts (little). It got even worse when some more broke recently, when my grandson some peeled off, using exhibit created by the keys already disappeared.
Thank you!
Hello Mike
Read your ad I don't understand exactly what is wrong with your keyboard but deleting and creating keycaps (plastic with written symbol) is not problematic. You have to just put this right into place and push it gently. You will hear a click and the key CAP will be back to the square.
Under this cap is placed small plastic mechanism. It contains two small plastic parts. If they are deleted from the bottom, you can put them inside once again. To see how it looks like to remove any other key cap and see how it is placed.
I did the same today, and with a little patience you can put it in the right position again.
