MinnowBoard.org recently announced the MinnowBoard Max which is a new Intel-powered development board with improved specifications and a $100 lower price versus the original MinnowBoard. The MinnowBoard Max is an open source hardware and software development platform designed and built by CircuitCo with guidance from Intel. The MinnowBoard Max is intended to be used to develop new Bay Trail-powered products or as the brain of embedded equipment that interacts with custom I/O such as FGPAs and specialized sensors.

The MinnowBoard Max is slightly smaller than the original at 2.9” x 3.9” and features an improved Intel Atom processor. Rather than the single core Atom E640 at 1 GHz the original MinnowBoard used, the MinnowBoard Max uses one of two Bay Trail Atom E3800-series SoCs. The base $99 model uses a single core Atom E3815 clocked at 1.46GHz while the $129 model uses a dual core Atom E3825 clocked at 1.33 GHz. The SoC is paired with either 1GB or 2GB of system RAM on the $99 or $129 model respectively.

The MinnowBoard Max supports a wide range of I/O including:

  • 26-pin low speed expansion port
    • SPI, I2C, I2S Audio, 2 x UARTs (TTL-level), 8 x buffered GPIO (two supporting PWM), +5V, Ground
  • 60-pin high speed expansion port
    • 1 x PCI-E 2.0 (one lane), 1 x SATA 3Gbps, 1 x USB 2.0 host, I2C, GPIO, JTAG, +5V, Ground
  • 1 x USB 3.0 port
  • 1 x USB 2.0 port
  • 1 x HDMI port
  • 1 x Micro SD
  • 1 x Gigabit Ethernet
  • 1 x Serial Debug (via separately sold cable)
  • 1 x Micro USB 2.0

The small form factor board supports Linux and Android operating systems with pending support for the Yocto Project (which helps developers create their own Linux distribution). Intel’s Bay Trail is not open source, but the company has reportedly provided open source drivers for the HD Graphics processor-integrated GPU.

The MinnowBoard Max starts at $99 and is slated to start shipping towards the end of June 2014. MinnowBoar.org will also be releasing the hardware design files under a Creative Commons license shortly after that launch point. More information can be found on the MinnowBoard Max FAQ.

The open source MinnowBoard Max looks to be a respectable upgrade over the original, and the lower price should help to make the x86 architecture more attractive to developers of embedded systems especially in the wake of the proliferation of ARM-powered alternatives.

Get to know your network better with Linux

Over at Linux.com is a look at five network monitoring tools that will really help you determine not only what is utilizing your network but also its overall health.  Bandwidthd is a tool for web hosts and LAN admins which tallies up incoming and outgoing bandwidth usage and can present it in a variety of time frames, from usage per day to usage per year.  Nethogs tracks usage per process and Darkstat tracks total usage but comes with an embedded HTTP server which makes it fairly self contained.  Speedometer is fairly self explanatory and to understand iperf you should read the write up here as it is a powerful tool for investigating the quality of your network.

A wee little Linux bug

Subject: General Tech | March 5, 2014 - 02:47 PM |
Tagged: linux, security

It would seem that there is a fairly problematic bug in the way that GnuTLS library applies encryption for many Linux users.  According to the story on The Inquirer this bug could allow an improperly setup certificate to be reported as valid and while your connection states it is secure it will not in fact be encrypted.  Red Hat has already issued a patch to solve this problem but the vulnerability would apply to any distro which uses the GnuTLS library.  It would be wise to follow the link from the story to locate a patch for your system before attackers start using it in the wild.

"THOUSANDS OF LINUX USERS might be vulnerable to hackers after it emerged that a significant certificate checking bug exists in a low level library.

The problem stems from the GnuTLS library that provides an API to enable SSL, TLS and DTLS encryption protocols, as used particularly by web servers."

"Chromebooks are amazing little machines. They are a marvel of speed and simplicity. The Acer C720 Chromebook is certainly near the top of the list of Chromebooks to be purchased (next to the Chromebook Pixel, of course). It's speedy and it's inexpensive. But for some, the simplistic nature of the devices doesn't offer enough power or flexibility. For those who need more from this Acer platform, I have the answer – in fact, I have two answers."

Kaveri loves fast memory

Subject: Editorial, General Tech | February 25, 2014 - 03:34 PM |
Tagged: ddr3, Kaveri, A10 7850K, amd, linux

You don't often see performance scaling as clean as what Phoronix saw when testing the effect of memory speed on AMD's A10-7850K.  Pick any result and you can clearly see a smooth increase in performance from DDR3-800 to DDR3-2400.  The only time that increase seems to decline slightly is between DDR3-2133 and 2400MHz, with some tests showing little to no increase between those two speeds.  Some tests do still show an improvement, for certain workloads on Linux the extra money is worth it but in other cases you can save a few dollars and limit yourself to the slightly cheaper DDR3-2133.  Check out the full review here.

"Earlier in the week I published benchmarks showing AMD Kaveri's DDR3-800MHz through DDR3-2133MHz system memory performance. Those results showed this latest-generation AMD APU craving -- and being able to take advantage of -- high memory frequencies. Many were curious how DDR3-2400MHz would fair with Kaveri so here's some benchmarks as we test out Kingston's HyperX Beast 8GB DDR3-2400MHz memory kit."

Tagged: windows 8, SFF, mintbox, linux, ipc2, haswell, compulab

CompuLab, the company behind the MintBox, launched its small form factor Intense PC 2 last month in four SKUs using Intel's latest Haswell processors. The systems are now available for purchase starting at $388 for the base model. The Intense PC 2 shares a similar form factor to the existing Intense PC and MintBox systems (resembling a consumer router), but features new hardware and IO options.

CompuLab IPC2.png

The Intense PC 2 measures 6.3” x 7.4”x 1.57” and has an aluminum chassis that acts as a passive heatsink for the internal components. The case is dark gray with a finned top surface. The front of the system can be customized with FACE modules that offer different IO options. However, by default the Intense PC 2 has two USB 3.0 ports and three indicator LEDs on the front and the following IO ports on the rear:

  • 2 x Gigabit Ethernet ports (Intel NICs)
  • 2 x HDMI video outputs
  • 1 x DisplayPort video output
  • 2 x USB 3.0
  • 2 x USB 2.0
  • 3 x RS232
  • 3 x (2 x analog, 1 x digital S/PDIF)
  • 1 x SIM card slot
  • 2 x antenna connectors

The FACE modules can expand connectivity to include VGA ouptuts, video capture inputs, additional networking, and additional USB ports (among other options).

Internally, the Intense PC 2 has a small motherboard that comes with an Intel Celeron, i3, i5, or i7 Haswell processor, up to 16GB of DDR3L 1600 MHz memory (two slots), a single mSATA port, and a single mPCIE port (the mSATA port is a combo mSATA/mPCIe port). An 802.11ac+Bluetooth 4.0 radio is included as part of the package. The 15W TDP CPU can be passively cooled, and at the high end you can get up to an Intel Core i7 4600U with HD 4400 graphics. The dual core (plus hyperthreading) chip can turbo up to 3.3 GHz. The table below from the CompuLab specification sheet (PDF) details the hardware layouts of the various IPC2 SKUs.

The Intense PC 2 is aimed at desktop users as well as the industrial sector. The passively cooled mini PC can be easily used as a desktop, home server, router+802.11ac access point, HTPC, or Steambox (streaming endpoint mainly), for example. It is also capable of driving signage and large 4K displays for adversiting and other tasks.

Tagged: linux, nuc, Bay Trail

If you are thinking of saving some money when picking up a NUC by skipping Windows and using Linux instead then Phoronix has two articles you should be reading before you order.  The initial testing on the Bay Trail processor did not go as well as hoped even if the architecture is based on Haswell but now that they have been on the market for a bit it is time to revisit them.  If you are just concerned about the performance then quickly pop over and read this article.  On the other hand if you want the full story then not only should you read that article but make sure to catch their full review here.

"With the early Atom "Bay Trail" hardware being disastrous for Linux, when Intel recently announced their Bay Trail based NUC Kit we were anxious and decided to give this unit a go. The Intel NUC Kit DN2820FYK packs an Intel Celeron N2820 Bay Trail CPU and motherboard supporting up to 8GB of DDR3L system memory and 2.5-inch HDD/SSD in a 116 x 112 x 51 mm form-factor. In this article is a rundown of the Phoronix experience so far for this Atom NUC Kit and how well it's running with Ubuntu Linux."

Develop for Debian; get free games

Subject: General Tech | January 27, 2014 - 02:01 PM |
Tagged: linux, debian, valve, free

Valve has an obvious favourite flavour of Linux as revealed by the free games they will be showering Debian developers with.  Any and all Valve published games, past or future, will be made available to developers for free.  This makes sense as SteamOS is branched from Debian 7.1 "Wheezy", making it very worth Valve's time and money to make friends with developers for Debian.  Maybe it is time to update your coding skills and become a developer; The Register didn't specify that Half Life 3 will be out first on Linux but do you really want to run that risk?

NVIDIA still holds the OpenGL crown on Linux; AMD is getting better though

Subject: General Tech | January 23, 2014 - 02:58 PM |
Tagged: opengl, linux, amd, nvidia

If you are a Linux user who prefers to use OpenGL graphics there is still a huge benefit to choosing NVIDIA over AMD.  The tests Phoronix just completed show that the GTX680, 770 and 780 all perform significantly faster than the R9 290 with even the older GTX 550 Ti and 650 GPUs outperforming AMD's best in some benchmarks.  That said AMD is making important improvements to their open source drivers as that is where they are lagging behind NVIDIA.  The new RadeonSI Gallium3D for the HD7000 series shows significant performance improvements when paired with the new 3.13 kernel though still falling a bit behind the Catalyst driver they are now much closer to the performance of the proprietary driver.  For older cards the performance increase is nowhere near as impressive but some certain benchmarks do show this Gallium3D driver to provide at least some improvements.  Pity the Source engine isn't behaving properly during benchmarks which is why no tests were run on Valve's games but that should be solved in the near future.

"In new tests conducted last week with the latest AMD and NVIDIA binary graphics drivers, the high-end AMD GPUs still really aren't proving much competition to NVIDIA's Kepler graphics cards. Here's a new 12 graphics card comparison on Ubuntu."
