Problem-solving has long been known to improve brain function, but finding the right games or a partner to play with has sometimes made it difficult to exercise these skills on a regular basis. Today young and old alike are finding fun challenges and cognitive boosters in online games targeting memory and responsiveness. Puzzle games such as Mahjong or Sudoku, trivia games like Slingo MatchUms and strategy games like Quiximity are easy to learn and start playing, yet offer an ongoing challenge for players.action girl games online

Have you tried using MEMORY tables? It’s a bit like a MySQL-supported ramdisk. I use them a lot, due to performance reasons, but I don’t know which is the fastest method:
- MEMORY table
- MyISAM on ramdisk
- InnoDB on ramdisk (if possible at all)

Comment on Force Firefox to save passwords even if the page disables autocomplete by gigel

gigel — Wed, 28 Mar 2012 08:53:11 +0000

this does not work with gmail logins under firefox 12 beta
i opened omni.ja, modified nsLoginManager.js BUT gmails’ login form does not have an “autocomplete=off” field in the html tag.
you can look at it with firefox’ web developer tools, by right clicking on the username field and choose inspect element.

does anyone know what is the workaround?

There are many free dating online sites online these days. I like to register with the websites that offer instant approval process like this one. Some other sites make new members to wait for a day or two before their profiles activate. This free dating site checks your profile immediately and you will be approved or rejected right away. I like this fast process so I still have time to search for the right match. Thanks for sharing this beautiful free dating service.

Comment on McAfee anti virus mcshield.exe process eats 100% CPU too often by Chris

Chris — Thu, 15 Mar 2012 13:16:07 +0000

Have you excluded your log files from your virus scanner ? I had a similar issue to this and I think it may well have been McAfee, basically our app generated a large amount of log churn and it kept kicking in, the trick was to exclude these files.

Comment on Heap dump of a running JVM with jmap by Onkar Joshi

Onkar Joshi — Wed, 01 Feb 2012 23:39:51 +0000

@Dan
True. JVisualVM is easier to use. But there can be problems with GUI access, firewalls and additional authentication such as Kerberos to deal with in “corporate” environments.

Comment on Heap dump of a running JVM with jmap by Daniel Shearer

Daniel Shearer — Wed, 01 Feb 2012 15:50:25 +0000

I normally get take my heap dumps using jvisualvm.
With the MBeans plugin enabled you can go to MBeans tab and select: com.sun.management -> HotSpotDiagnostic.
Under the ‘operations’ tab there is a dumpHeap button. The two options it takes are:
1. filename. If you don’t specify a directory it will go into the processes current working directory.
2. Should the heap dump exclude anything eligible for garbage collection.

Jonny — Fri, 27 Jan 2012 10:41:20 +0000

My child mapping is LAZY and I got around it by lazily initializing the setter.

void setSet(Set set)
{
if (this.set == null)
this.set = set;
else
{
this.set.retainAll(set);
this.set.addAll(set);
}
}

Be careful, if the child collection is mapped as LAZY, clear() it will not work as expected.

Comment on Shaadi.com is a waste of time by Anu

Anu — Mon, 24 Oct 2011 02:16:27 +0000

I have reported to Shaadi many time of the amount of Nigerian scammers working through their sight and 1 year on and there is still no change. Its clearly a huge problem as i appear not to be the only one that has encountered this problem. For me they are now very easy to spot and i have pointed out these ‘easy to spot’ signs yet Shaadi appear to be nothing to stop them. The sad this is that Shaadi are loosing credibility to me it looks as though they arn’t too bothered as they are now perhaps just a money making machine after all its a numbers game right?

There could be many reasons.

Look out for firewall issues.

Try connecting with a well known client such as FileZilla to see if things work fine.

Just a small note, FileZilla does not support SFTP either. On windows you’ll have to find a different server. Solaris on the other hand supports SFTP out of the box but I haven’t found anything yet that says whether or not it supports FTPS in the same manner. Great post by the way, summed the answers for a lot of the questions I had for FTP up well in a single response.
