Ubuntu 9.04 Boots in 21.4 Seconds - With EXT4 as the default filesystem. - Softpedia

There are only two days left until the third Alpha version of the upcoming Ubuntu 9.04 (Jaunty Jackalope) will be available (for testing), and... we couldn't resist the temptation to take the current daily build for a test drive, before our usual screenshot tour, and taste the "sweetness" of that evolutionary EXT4 Linux filesystem. Announced on Christmas Eve, the EXT4 filesystem is now declared stable and it is distributed with version 2.6.28 of the Linux kernel and later. However, the good news is that the EXT4 filesystem was implemented in the upcoming Ubuntu 9.04 Alpha 3 a couple of days ago and it will be available in the Ubuntu Installer, if you choose manual partitioning (see the screenshot below for details). The bad news is that EXT4 will not be the default filesystem for the Ubuntu OS until version 9.10, due for release in late October this year.

OK, OK... so how will the end user benefit from this EXT4 filesystem? Well, first of all, the whole system will be much faster and more reliable compared to one with EXT3 (I guess that some of you still remember the Firefox/Ext3 issue), it will boot faster (the current article proves that) and it's able to handle files with sizes of up to 16 TB (terabytes). But these are just a few of the features brought by the fourth extended filesystem, for more details you can check the Wikipedia entry for EXT4.

New Pop!_OS Update Makes (Some) Computers Faster

Image
A small update rolling out to the Ubuntu-based   Pop!_OS   distro could make a big impact on system performance. Pop!_OS now enables  zram  support by default — and to  quote Sytem76  themselves the feature  “actively compresses memory in the background, increasing the amount of free memory your system has available. This results in increased FPS in games, or faster simulations and compiler runs.” Pretty nice, eh? Instead of moving infrequently used data to a separate swap partition on disk (which is slow), zram compresses data, and keeps it in RAM (which is faster). On systems with lower amounts of RAM available zram allows more available memory to be used for runnings apps and games. Though I’m yet to try it on Pop!_OS, zram is something I use on several devices as  Fedora enabled zram  a few years back. Though I don’t come bearing any graphs to back the enthusiasm up, it’s something I definitely  think  I feel the benefit of, even for basic computing needs. Still, it’s not just thos

Ubuntu’s New Installer is Shaping Up Nicely

Image
  Ubuntu’s been working on its   new OS installer   for a couple years, now it looks like the upcoming Ubuntu 23.04 ‘Lunar Lobster’ release will finally ship it by default. The latest pending  Ubuntu 23.04 daily builds  use the reworked installer by default, and is expected to power the default install experience of the Ubuntu 23.03 beta in March. Thing is, despite the fact the installer is built using an entirely different toolkit ( Flutter ) and now leverages the Ubuntu’s  server-based  Subiquity  and  Curtin  efforts, it doesn’t look  that  different to the existing one. In fact, if no-one told you the installer was rebuilt you’d probably never tell. The new installer was available to test in previous versions of Ubuntu using a special ‘canary’ ISO, and is also  available as a Snap  app you can run (but shouldn’t) on an existing Ubuntu install. Now the Flutter-based front-end has filtered out in the official daily builds — so let’s go hands on to see how it performs! Ubuntu’s New In
