Mozilla Project MemShrink Looks Into Speeding Up Firefox
Firefox has a long standing history of excessive memory usage and slow startups. No matter how much of tweaking and customization we make, Firefox will still remain the same slow browser. This is finally identified as a problem at Mozilla and they are working on fixing the biggest annoyance in Firefox: the speed issues.
When I talk about speed in this post, it is not related to the speed of surfing the Internet. I am talking about the responsiveness and startup of Firefox. The long waiting hours will soon be over and project MemShrink is here to make sure of that.
MemShrink is a project that aims to reduce Firefox’s memory consumption. There are three potential benefits:
- Speed: less cache pressure, and less paging. The latter is crucial, as it can destroy performance.
- Stability: fewer OOMs, whether due to address space exhaustion or otherwise. This results in fewer crashes (due to mishandling of OOM) or aborts.
- Perception: fewer people will complain about Firefox being a memory hog.
From what this page tells me, Mozilla has a number of leaks to take care of which have piled up over time. Mozilla developer Johnny Stenback has talked of the project MemShrink saying,
to help get more attention to this issue we’ll be starting up a MemShrink effort, where a group of people will get together to look at the big picture, triage bugs, investigate general approaches, and do some brainstorming.
One positive outcome from this will definitely be some improvement on Firefox memory usage, which shoots up with time and does that abnormally. The same problem is encountered on other browsers as well and sometimes, the Windows Task Manager cannot be trusted for correct memory usage readings. The fact is, Firefox is slow and this needs to change in future versions.
Motorola Droid X And Defy Get A CyanogenMod 7 Port
Motorola Android phones are generally feature packed to the core, and sport decent specs as well. The Motorola Droid X was one of the most popular Android handsets in the U.S. last year.
However, Motorola phones have not been a favorite among the developers and modders, because of their encrypted boot loader. The encrypted boot loader meant that there was not much scope for a true ‘Custom ROM’ for Motorola handsets. The company has been receiving a lot of criticism for the same, and they have promised to do something about this.
Now, a Motorola Droid X developer – @cvpcs – has managed to get the most popular AOSP based custom ROM – CyanogenMod 7 – to the handset. He used a ‘2nd-init’ method to get the ROM up and working on the Droid X. However, this by any chance does not mean that the Droid X boot loader has been cracked. Due to this, he is forced to use the stock Motorola kernel that shipped with the device.
Below is a video of CM7 in action on the Droid X –:
The developer (cvpcs) still has not made the CM7 port available for Droid X owners though. He is still testing the port for some bugs, and will soon release it to the public.
Other Motorola devices like the Droid 2 should also get this CM7 port up and working, since both the handsets are very similar. In fact, the Motorola Defy has already got a working CM7 port. Defy owners should head over to this thread over at XDA forums for more information.
Nissan LEAF In-Car Computer Leaks Location Information
The Nissan LEAF (Leading, Environmentally friendly, Affordable, Family) car is currently being put through the paces in the hands of Casey Halverson, a network engineer at InfoSpace. At the heart of the LEAF is CARWINGS, a “telematics system” used for plotting and displaying various internal functions such as energy consumption, charge status as well as the ability to display content pulled from the internet. Nissan has taken the technology of the car and is attempting to empower users with it by providing information about the car instantly through iPhone apps and an always-connected web app. Unfortunate for many LEAF owners, it would seem that Nissan may have overlooked customer privacy when developing the system.
In addition to requesting data through an RSS feed, CARWINGS takes it upon itself to pass along your current location in the form of GPS co-ordinates, speed, direction and more. What’s worse, is that any configured feed is given the information and it can be harvested by third parties.
While there are many legitimate uses for providing these details, such as location-aware feeds for weather, driving directions or even traffic details – it would seem that at no time is this told to users and no option is available for opting out.
A video documentation shows off CARWINGS in use, set up with a simple feed that takes the information the LEAF has stored and provides it back to the user. Whether or not LEAF owners will consider this a gross invasion of privacy due to how such information can be leverage or if they find it a nice luxury that they don’t have to enter in their current location to see it’s raining will largely depend on how Nissan explains to the general customer why they share this information.

AMD resurrects FX branding for eight-core Bulldozer processor
AMD is dusting off an old chestnut as it looks to reinvigorate its relationship with PC enthusiasts. The company has announced that it’s bringing the FX moniker back for its latest desktop performance platform.
The FX label was originally conceived for AMD’s gaming platforms, and its resurrection comes in time for its upcoming Scorpius platform, which [...]

Citigroup hacked: What to do if your account was compromised
Some 200,000 of Citigroup's bankcard customers had their accounts hacked. Most won't be responsible for fraudulent purchases, but cardholders should still take precautions.
Periodic Table Gets Longer With Addition Of Two New Elements
The Periodic Table of chemical elements just got longer. Two new elements, having atomic numbers 114 and 116 have been added to the list, which already contains elements till atomic number 112 with no intermediate gaps. These new elements have not been named as yet and are now known only by their scientific names.
The Periodic Table
The Periodic Table is a table of all known chemical elements arranged according to increasing atomic number (Atomic number is the number of protons in the nucleus of an atom of the element). This kind of arrangement is particularly useful from the point of view of chemistry because it helps uncover great amounts of information by using the concept of periodicity of properties of elements. For example, Sulphur, placed below Oxygen, behaves very much like Oxygen in many chemical reactions, just like Silicon is similar to Carbon.
The Periodic Table
The Addition
This addition comes after a three-year review by the governing bodies of chemistry and physics, namely International Union of Pure and Applied Chemistry (IUPAC) and International Union of Pure and Applied Physics (IUPAP). There have been many claims to the fabrication of new substances with atomic numbers 113, 114, 115, 116 and 118. Only 114 and 116 have been cleared for addition into the Periodic Table. Both elements were made by a collaborative team comprising scientists from the Nuclear Research in Dubna, Russia and Lawrence Livermore National Laboratory, California.
All elements above element no. 92 (Uranium) are artificially made, as they are not found in nature. All of them are radioactive, some highly so. Elements 114 and 116 are also very radioactive with a half-life of less than a second. Heavier elements are known to be more unstable. Interestingly, no group claimed to have made element number 117. The concept of magic numbers in physics tells us that element number 126 maybe more stable than expected, but we are still far from there.
Wedding rings, presumably to be exchanged between two enthusiastic chemists. Better make two more of these now!
Naming
Naming of these new elements is given by the guidelines set by IUPAC. Element number 114 is named ununquadium. Don’t get scared, there’s really nothing to it. The 1’s in 114 give ‘un’. The last 4 gives ‘quad’. Metallic nature gives the ending ‘ium’. Similarly, element no. 116 is known as ununhexium, ‘hex’ coming from the 6. The hypothetical 117 would be ununheptium and so on…
Gone are the days when making a new element could be compared to the mystical art of alchemy. You don’t get a Nobel Prize, unlike Madame Curie, for making new elements nowadays. It’s still a challenge, but it’s not as difficult as it used to be. Chemistry students may be rest assured that these new elements won’t add to their course material.
