In my last update of Firefox (13.0), they seem to be trying to copy Opera's selection screen (which I like) where you can select from 9 web sites. Unfortunately, it doesn't seem to work well at all:
1) There doesn't appear to be an option to manually change the selections, they just populate with random recently visited pages, including many different pages from the same site.
2) The is an X to remove unwanted selections, but they just repopulate the page when I next visit those sites.
3) There's also a push-pin which supposedly makes the selection a permanent addition to the screen, but doesn't seem to work. The next time I restart Firefox, I get a new random assortment of selections. And, sometimes when I use the push-pin, that selection deletes instead, as if I had hit the X.
4) Each selection has text only, no image, and the text is the title of that web page, with no option to change it.
So, is this new feature just "not ready for prime time", or is this really how they designed it to work ? StuRat ( talk) 00:32, 9 June 2012 (UTC)

00:36, 9 June 2012 (UTC)Hi there, Microsoft Windows 7 and Microsoft Windows XP. Consistently use Windows 7 to store photos and now find that like rabbits they keep on duplicating, this seems to be happening on the older XP also. Advised that if this continues it will eventually crash the computer! Have searched Microsoft for any downloads but find I am referred to another company which I suspect uses a Corporation in India, and my experience tells me to keep well away. Is there any free software that will fix this problem - or software at a one off cost - or any other solution? How binding is the agreement you agree to online to access the supposedly free download product? Clicked off and uninstalled product when the monthly cost came up. Eyesight does not allow me to scrutinize online contracts. Probably too old and old fashioned, but should not any company provide immediate free downloads to fix problems on their own product after you purchase it? Would it be a temporary solution to download all pictures on to a USB stick and then delete all pictures until problem is solved? Have all Microsoft latest updates automatically set to download, but apparently not one for this problem!!
Help!!!!

Hello. I've begun to notice that pdf's of scanned documents are unnaturally slow - for example http://archive.org/details/gentshistoryhul01ohlsgoog (or any other from this site, or a downloaded pdf from google books)
Using the download link page
http://ia600404.us.archive.org/13/items/gentshistoryhul01ohlsgoog/ - comparing .djvu , .pdf , and the jp2.zip files after decompressing. (using adobe, caminova, and picassa ACDsee to view)
On my (admittedly slow XP 32bit) machine (using single page, non-scrolling view) it takes nearly a second (or a good fraction) of to get the next page displayed after pressing PgDn. On the .djvu or .jpg file it is nearly instantaneous. To add insult the .pdf file doesn't appear to contain any text data - so effectively it's just a slideshow. Task manager shows .pdf uses much more cpu - the situation is just the same with google chromes built in pdf viewer.. (it's clearly not hard-disk bandwidth as the jpg slideshow is far faster)
So - is there an simple explanation for this? - are there better pdf viewers?, why is pdf such a dog for images? Oranjblud ( talk) 13:43, 9 June 2012 (UTC)
ok, thanks. It looks likely the decompression is to blame. At least I know it's not just me. Not much I can do about this in the short term, except use the djvu when available. On the other hand the idea of using OCR'd data for text image compression is an interesting one (although JBIG doesn't seem to explicitly try to do this - maybe mk.2 should..)
Seeing as the compression appears to be the problem I think I might try printing the pdf - using print to pdf software to get an uncompressed pdf - and see if that helps at all.. Oranjblud ( talk) 00:36, 10 June 2012 (UTC)
I have read that a lot of Intel's chips are the same with certain features "fused off". What does this mean and does this have anything to do with silicon fuses? Are there any Intel chips that cannot be "fused off" as in they are entirely static in their structure? -- Melab±1 ☎ 15:36, 9 June 2012 (UTC)
Sir my doubt is about correlated subquery execution When it has more than one sub query. I know correlated subquery execution when it has one sub query.but if it has more than one sub query I am not able to understand. I have refferd so many books and web sites.but I could not find it. Finally I am asking you. for me you spend some time and give detailed answer Below there are two queries.i know execution of query1.but I do not know execution of query 2. I am asking my doubts by comparing with query1.you please read clear my doubt.do not think this big doubt.i am expressing my doubt clearly .so it became big doubt.
query 1: Select e.ename,e.city from emp1 e where exists(select f.ename from emp2 f where f.ename=’ajay’ and e.city=f.city));
Query2: Select e.ename from employee e where exists(select ‘x’ from emp_company c where e.ename=c.ename and exists(select ‘x’ from company m where c.cname =m.cname and m.city=’bombay’));--
Doubt1: In first step of execution of query1 ,employee table’s first row ename,city considered. Then what happens in first step of execution of query2.
Doubt2: In second step of execution of query1 ,the considered city from main query is compared with every row of emp2. What happens in second step of execution of query2.?
third step of execution of query1:
while comparing city from main query with every row of emp2,if any row satisfies condition that rows ename is added to a list. What happens in 3rd step of execution of query2.?
In 4th step of execution of query1 ,the formed list is returned. To main query. What happens in 4th step of execution of query2.?
In 5th step of execution of query1,if the returned list is not empty then exists evaluates to true.then emp1 table’s ename,city added out put. What happens in 5th step of execution of query2.?
In 6th step of execution of query1 emp1 ename,city are selected from second row of emp1 table. What happens in 6th step of execution of query2.?
Can You please explain execution of query2 as I explained query1?. — Preceding unsigned comment added by Phanihup ( talk • contribs) 16:42, 9 June 2012 (UTC)
