April Fools Day is once again upon us and as usual, tech companies everywhere have not failed to keep us entertained. With a trove of fantastic faux product launches and even some real product launches that were taken as April Fools jokes, people have been busy releasing their hilarious ideas. With many of these jokes being nostalgic and some even being functional it's easy to appreciate the spirit behind them. Samsung Galaxy Blade Edge In a reference to the Galaxy...
Ext4 Speed Improvement for Nexus S
XDA member supercurio has been working on the Ext4 file system for a little while now, and you may remember that there are results out of that already for the Nexus S with this improved kernel. But what is this about? In essence, the use of a safe mount option would allow the device to perform certain internal tasks better without compromising data integrity or file system integrity if the system was to fail for some reason (crash).
There has been some benchmarking done for his work and it seems to get a significant boost after this option is enabled. The dev also states that the benchmark used (Quadrant), while not really crucial, it would yield interesting information for comparison purposes. The whole discussion is rather technical, but we thought it was still worth pointing it out as a reference. After all, some people may wonder why their Nexus S is running faster all of the sudden
As I spend some time on studying Ext4 for the Galaxy S devices, working on Voodoo lagfix, and based on what I saw in mount logs it’s possible that the performances could be increased without altering data integrity nor filesystem integrity in case of crash.
On /data, noauto_da_alloc is not used.
This option activates a sort of Ext3 emulation mode, which force sync on write close without sync.
It also comes with a speed penalty for SQLite writes, and is unneccessary when hardware barriers are enabled.
Barriers allow usage of delayed allocations without risk. Delayed allocations are the key to performance for modern filesystems.

The beginning of April is dominated by April Fools. There are jokes and pranks everywhere, which are meant to fool people. This news is no joke though, as Google has pushed the shiny red button to send out over-the-air updates to supported devices. Well, sort of, as only a few of available Nexus devices got updates to Android 5.1. Here's a list of OTAs that can be downloaded and flashed by stock recoveries. You can find guides on how to revert...
Once again, we have arrived on the most magical of holidays - the annual unveiling of HalfLife 3, and day on which co-workers believe it is appropriate to duct tape air horns behind doors. I speak, of course, about April Fools Day. As has become their custom, Google launched lighthearted "pranks" for each of their various services (with other tech sites and vendors following suit), and we have done our best to round up the humorous products and tweaks surfacing thus far....
