Mozilla’s Memory Issue solved

Mozilla’s 6-week release cycle is a bold
new step that ensures frequent release of updates, and users will now
get the new features faster than ever. The latest stable release of
Firefox is a big leap forward for Mozilla as it solves the oldest,
biggest and probably one of the most irritating  of bugs in the browser,
the memory bug.
As posted on Mozilla’s support forum Mozillazine,
“Firefox caches objects for future use. In addition, memory becomes
fragmented as memory is repeatedly allocated and de-allocated. This
general increase is normal.[1]” In other words, Firefox can’t efficiently return the memory it allocates when it’s no longer needed by it.
Those who keep 10/15+ tabs open at the
same time will know how irritating it gets when the system memory gets
sloppy. Stream two videos at the same time on youtube while checking
updates on Facebook or browsing picture galleries, and everything
freezes up. Browser crashes and unresponsive video drivers were a common
occurence in Firefox 5 and older. There were hacks in the about:config
page to solve this issue but they weren’t guaranteed to work, definitely
not up to the level we needed it to work. They weren’t much help to me
at least.
Firefox 5 was an even bigger memory hog than the previous releases. Even the Memoryfox Addon (here) couldn’t do much. (Firefox 6 had buttons added in the about:memory page to do the memory flushing.)
But Firefox developers have finally
taken the matter seriously and Mozilla claims that in Firefox 7 and
onwards the memory leakage problem will  be solved.
I’ve been using the browser (Firefox 7)
for a week now and it does feel faster than Firefox 5 or 6.  Memory
leakage, not gone but considerably reduced as memory usage by Firefox 7
is much less after long use compared to Firefox 5. Firefox 8, which is
still in beta, doesn’t add anything more to memory management compared
to Firefox 7, but then again, it has more than a month left for its
scheduled release.
Also, at the time of writing of this
article, both the Aurora and the Nightly builds of Firefox, feel a lot
faster. Try pages with lots of graphics, pictures, videos and lots of
different colors, open on 10 or more tabs, and it still has no problems
while switching between tabs. Personally I’ve had no problems switching
between 20 tabs, most of them full of pictures, while logged on to all
three of Facebook, twitter and google+ (doing all this would either
cause your display to freeze or your browser to crash on Firefox 5).
Many users have said that Firefox 7 is just as good with 40+ tabs as
well.
With the developments that we see in these beta releases and
considering the all that time still left for the final release of
Firefox 8, 9 and 10 (For now these are the beta, aurora and nightly
builds until their stable versions are out. You can download them from
from here and here), it is certain that these new versions do have something to offer. You can learn more about these builds here.

Find out the mail server without using any 3rd party tool

Myself being a mail/web solution provider, always juggles with various mail related queries. Infact fond of playing with mail servers. With more than 2 years in the EMAIL hosting business, I am ready to take any task related to Web solutions.
As I provide Push Email service(customized EMAIL solutions) to clients ranging from big Corporate and Multi-National Companies, Small retail vendors and even individuals, I’ve subscribed to various paid service to track down DNS related stuffs. Where i can get an idea whether Name server has been resolved or not. In short i am completely dependent on these 3rd party paid tools for NS, MX, A, CNAME, AAA, SOA, SRV DNS entries.
One late night i was in Sedan with my personal notebook, on the way to home. Suddenly one of my client pinged on BB Msgr, just to know whether his domain has been transferred to managed server or not. As s/he was in worry, of losing corporate mails during downtime. The moment s/he buzzed I switched on the machine, and clicked on small Internet Explorer icon from the taskbar. Unfortunately it got crashed, due to installation of some wrong unstable pluggin in last update. Err!!! As said earlier, it was my personal small notebook, so using Windows with having single default browser IE (which i hate most. Undoubtedly Mozilla Firefox is every open source lover’s 1st choice). Now I was in a situation to either tell my client blindly any thing(which i hate), or to find some really good stuff to let my-self know the exact current status of Name server/MX point status.
After putting lots of pressure and stress on me, I succeeded to recall few set of commands, which i had read couple of years earlier in one Hacking journal. This helped me to find out the mail server address for virtually any domain, without using any 3rd party tool. Here it goes(considering your are having Windows OS):
  • Open your command prompt (using win+R and type cmd)
  • Type nslookup
  • The prompt will change to >
  • Type set q=mx (for mail exchange)
  • Now type any domain name, you wish to find out server address for, e.g: swatantra.info
  • Now look for the MX preference lines.
  • These are the ones that list the various smtp/esmtp mail server addresses.. higher the preference no you choose the better.. because they’ll work smoother..
  • Once you get through, say exit to command prompt, to quit.
Huuh, till date i was using paid service.
