Ubuntu 14.04 / 15.04 Tested in Tronsmart Ara X5 Cherry Trail Mini PC

After reviewing Tronsmart Ara X5 with Windows 10, I decided to give a try at Ubuntu. Initially I downloaded Ubuntu 15.04 Desktop 64-bit ISO image, and prepare a bootable USB drive with UNetbootin in my computer running Ubuntu 14.04. But after inserting the USB flash drive into Ara X5, and pressing F7, there was no options to select the drive, so I went to UEFI settings, and the drive was clearly detected, but not available as a bootable device. Finally, having heard one company booted Ubuntu on MeegoPad T04 using Rufus, and Tronsmart confirming Ubuntu 14.04 could boot on Ara X5 using Pendrive Linux USB installer, I decided to try again with Windows tools, and prepared an Ubuntu 15.04 image with Rufus. Great! Pressing F7 would show the USB flash drive, and I could boot Ubuntu 15.04. But unfortunately audio output is not working (only Dummy output), nor is WiFi […]

Ubuntu 14.04.3 Desktop Image for Intel Atom Z3735F mini PCs and Sticks

If you’ve been trying to run Ubuntu on Intel Atom Z3735F, chances are that you’ve come across Ian Morrison (Linuxium) work, even MeegoPad T02 is using one of its older Ubuntu image (without his direct knowledge / authorization), and the developer has now released an Ubuntu 14.04.3 Desktop image for Intel Atom Z3735F based devices around five days after the official Canonical release. The official Ubuntu 14.04.3 includes the newer 3.19 Linux kernel from Ubuntu 15.04, and a matching X.org stack, and has been upgraded that way for hardware enablement, i.e. to support more hardware platforms. Unfortunately, the image for Z3735F is still using a 3.16 kernel because some dynamic kernel modules only work with 3.16. The image supports 32-bit and a 64-bit bootloaders and includes WiFi, Bluetooth, and Audio support. If you’d like to update Ubuntu on your device, download and flash ubuntu-14.04.3-desktop-linuxium.iso to a USB drive with ‘Rufus’ […]

Freescale i.MX6 DualPlus and QuadPlus SoCs Gets Faster 2D and 3D Graphics, Higher Memory Bandwidth

Freescale unveiled three new models for its i.MX 6 family processor for consumer, industrial and automotive markets in May. Two models are an upgrade to existing i.MX6 Quad and i.MX6 Dual processors, as the new i.MX 6QuadPlus and i.MX6DualPlus processors features four and two Cortex A9 cores, together with improved 2D and 3D GPUs delivering around 50% faster performance, an “optimized” SDRAM controller, more SRAM, and a prefetch and resolve engine. The third model, i.MX 6UltraLite, features a single ARM Cortex A7 core and hardware security, and targets applications such as electronic Point Of Sales (ePOS). That means there are now 9 i.MX6 processors, and today, I’ll focus on the two new “Plus” versions. Since they are based on the original i.MX6 Quad and i.MX6 Dual processors, the best way to have a look at these is to compare them to their predecessors. Features i.MX 6QuadPlus i.MX 6Quad i.MX 6DualPlus […]

ps_mem Shows Programs RAM Usage in Linux

There are several ways to see how much RAM is used in a Linux system with tools like free, vmstat, top, etc…, but today I’ve come across ps_mem which displays the RAM used for each program in a neat way. The post on lintut.com explains how to install it on Centos / Fedora:

yum install ps_mem -y

1	yum install ps_mem -y

As a Ubuntu user, I immediately tried apt-get install ps_mem, but there isn’t such package. After running apt-file search, I found it in w3af-console package:

sudo apt-get install w3af-console
sudo chmod +x /usr/share/w3af/core/controllers/profiling/ps_mem.py
sudo ln -s /usr/share/w3af/core/controllers/profiling/ps_mem.py /usr/sbin/ps_mem

sudo apt-get install w3af-console

sudo chmod +x /usr/share/w3af/core/controllers/profiling/ps_mem.py

sudo ln -s /usr/share/w3af/core/controllers/profiling/ps_mem.py /usr/sbin/ps_mem

Another way to install the script is to simply get it from Github. Running the command without options will list of programs with RAM usage from the smallest to the largest:

sudo ps_mem
