New PC Studio 1.5 (NPS)
I am regularly updating my Samsung New PC Studio like I described in my post in order to finally get the firmware updates for my Samsung Galaxy mobile phone. I’m expecting to upgrade the OS to Android 1.6 for quite some time, but the update is not coming yet.
The new version of NPS that I have downloaded from Samsung mobile UK is version 1.5 or as the filename says 1.5.1.10064_2 (the whole finame of the NPS is New_PC_Studio_1.5.1.10064_2.exe). It looks brand new and shiny – well it should, the download is 170 MB! The icons are new, the user interface is new, but what about functionalities? First a cold shower: when I connected my i7500 I got the well known message from other version that the only functionality that is supported in upgrading the phone’s firmware. Obviously Samsung completely forgot about i7500 and its user base and I think this is a bad decision.
The look of the screen was nice and intuitive because I’ve used the previous version. So I found the update icon with no problems, clicked on it, crossed my fingers — but the new NPS 1.5 informed me, that I have the latest version of firmware installed. Unfortunately, this version still has Android 1.5 beneath it.
So it looks like I’m still stuck with my new old phone.

Google Chrome uses much more memory than Firefox
I think of myself as a heavy Firefox user. I use the latest version of the browser (3.6.8) and a preview version of Firefox 4 with a different profile for testing and evaluating purposes. I have always opened two stable versions of Firefox with two different profiles at the same time (by using the -no-remote directive when running it). In my primary profile there’s arround 100 tabs open at any time, in my secondary profile I have around 10 tabs open. My profile has 40 add-ons installed.
At the same time I use Google Chrome also, mainly for evyluating it, but more and more often for playing Youtube videos and incognito mode. I am not a Chrome power user (yet) – there are still some important issues with Google Chrome, mainly based on system hogging.
Today I have checked the memory usage of all my opened browsers. My primary Firefox (with 100 opened tabs) uses around 800 kb, my secondary Firefox around 150 kb, and each Chrome process between 7 kb and 70 kb. I have 5 tabs open, but the number of Chrome processes is 13, probably because of the plugins. The top 5 processes (that I think are tabs) use between 30 kb and 70 kb.
I made a short calculation which I think is correct: If I open 100 tabs in Chrome, they would use up between 3 GB and 7 GB of memory. Compared to 800 kb in Firefox I conclude that Firefox in more memory efficient than Google Chrome for a large number of simultaneously opened tabs.
I think the difference is too big and is probably the reason why I find Chrome hogging my system.
