TuxMachines: Should we celebrate the anniversary of open source?

Wednesday 18th of July 2018 06:27:46 AM

Open source did not emerge from a void. It was consciously a marketing programme for the already-15-year-old idea of free software and arose in the context of both the GNU Project and the BSD community and their history (stretching back to the late 70s). We chose to reflect this in the agenda for our celebration track at OSCON.

But that doesn’t mean its inception is irrelevant. The consensus to define open source at the VA Linux meeting and the subsequent formation of OSI and acceptance of the Open Source Definition changed the phrase from descriptive to a term of art accepted globally. It created a movement and a market and consequently spread software freedom far beyond anyone’s expectations. That has to be worth celebrating.

Reddit: Questions about mesh Networks

Wednesday 18th of July 2018 06:13:53 AM

Alright well I was thinking about getting together with a couple friends and setting up satellites all around the our city to make a offline mesh network. So we can share files extremely fast and not eat up our data and gas.

Even thought about setting up a Plex server on the network for easy access to media. Since you can download it to any device. Also was going to use it for messaging and communications. Pretty much I was going to build a computer and have it be the main hub for everything!

Might use raspberry pies or something as repeaters to help with connection over long distance. Our town is pretty big and it would need to reach at least 20-25 miles. Does anyone know if this could be done? If so am I in the right direction or do I need to look at different avenues?

Reddit: Intercepting HTTP requests of a POS system?

Wednesday 18th of July 2018 03:57:32 AM

I have a project coming up where I would need to create a web service replacement for a proprietary cloud based takeaway system. The project is being done for a takeaway restaurant.

The flow is like this: - There is a receipt printer behind counter with online access - When an order is made through their website, an API call is made to the proprietary cloud service - The service pushes the order to the receipt printer - The shop owner picks a time of delivery on the receipt printer - The receipt is printed, and the customer is notified by the cloud service of the delivery time

Here's a video demo: - -

What I want to do is replace the cloud service, intercepting the HTTP calls the printer is making and responding to them.

How could I go about this? I have 2 options in mind:

  1. Use a raspberry pi as a middle man between the printer and the wifi router
  2. Configure the internal DNS of the router to point the domain name of the cloud service to my IP

Those options are both hard to do for people with little tech skill, which I don't expect these shop owners to have. Do you guys have any other ideas?

Reddit: Understanding the immutable bit and how to implement a chattr handler in FUSE.

Wednesday 18th of July 2018 03:28:19 AM

I'm trying to clear up something which I've found little and misleading docs on: the immutabile bit in files on ext4 Linux file systems. I have spotty knowledge on this derived from books, man pages, and forums so please bear with me.

I originally thought immutability was an extended attribute, and I'm basically modifying the end bits of a file when I set it. I decided to test this out by creating an inotify watch and watching the logs when I chattr a file. It turns out I trigger the close_nowrite handler instead of modify.

Ok so this doesn't make sense, and had me going in circles. At some point I came across setfattr when I was making an xattr handler for my own FUSE based filesystem, and it turns out that setfattr cannot set immutability the way I want to (to my knowledge). So immutability is probably not an xattr

Eventually I come across ioctl and the related inode flags, and think I'm getting somewhere by understanding that immutability is a flag that is part of the inode struct of a file. It is designated as an input output control flag, so henceforth I can use ioctl handlers and functions to control it in a FUSE filesystem.

Can you guys help me identify my gaps in my understanding?

TuxMachines: IIoT platform extends from the cloud to the depths of a mine

Wednesday 18th of July 2018 01:11:12 AM

Advantech announced an IoT platform initially targeting mine safety that combines BTI’s “MIOTY” LPWAN sensor solution running on an Ubuntu-powered Advantech ARK-2250L gateway connected to a Hitachi IoT Service Hub running on Microsoft Azure.

Because Industrial Internet of Things (IIoT) projects tend to be complex, multi-product endeavors, Advantech has lately been entering into IoT collaborations, such as its Embedded Linux & Android Alliance (ELAA) consortium and recently announced Solution Ready Packages (SRPs) cocreation program. Today at the Microsoft Inspire conference in Las Vegas, the company announced a new collaboration with Behr Technologies, Inc. (BTI), Hitachi Solutions America, and Microsoft on an end-to-end IIoT platform that will initially target the mining industry.

  • A Look at Google's Project Fi
    Project Fi is a play on the term "WiFi" and is pronounced "Project Fye", as opposed to "Project Fee", which is what I called it at first. Several features set Project Fi apart from other cell-phone plans. First, Project Fi uses towers from three carriers: T-Mobile, US Cellular and Sprint. When using supported hardware, Project Fi constantly monitors signal strength and seamlessly transitions between the various towers. Depending on where you live, this can mean constant access to the fastest network or a better chance of having any coverage at all. (I'm in the latter group, as I live in a rural area.)

    Medellín is well known for its innovative technology scene, with many active software and information technology user groups. One of those is the user group centered around open source content management software WordPress. A year ago the user group hosted Colombia’s first Wordcamp function, supported by the global WordPress community, and the user group recently gathered to celebrate the 15th anniversary of the first WordPress open source software release that took place May 27, 2003. WordPress is an free, open source software platform that allows amateur and professional users to create websites without writing programming code. Over the years it has grown into a powerful platform robust enough to run enterprise websites in many cases. For example, Finance Colombia runs on WordPress software.

But not everyone has access to such enormous grids and particularly in remote villages in developing nations, there is only a need for a single or small group of solar panels that could maintain maximum efficiency to sustain a family or the village itself.
  • Meet the man in charge of Arduino

    I went to visit the Interaction Design Institute of Ivrea – a school that was started just six months before I went to visit them – and they asked me if I knew someone who could teach electronics to designers and to ask this question to my colleagues at the Politecnico.

    I went back and they said “No! Teaching electronics to designers? For us?” Those were guys working on highly sophisticated FGPAs, so they didn’t care about designers. I thought about Massimo – he had a real passion for electronics and he worked as a CTO for an internet provider at that point in time. I said, “Massimo, you could be the right person for this type of engagement – they’re designers, you love design, and you know electronics.” I introduced Massimo to the school and they hired him. That’s how the story started. When he was teaching at the Design Institute of Ivrea, they started the Arduino project as a way to standardise the electronics projects the students were doing. I introduced Massimo to the school and they invented Arduino, so I’m sort of the great-grandfather to some extent.
