Github Has Restricted Accounts of Users from US Sanctioned Countries

Countries such as North Korea, Iran, or Syria, as well as specific zones such as Crimea, are US sanctioned countries, meaning you are not supposed to do business with them. If you’ve recently opened a business bank account, you may have had to sign a document confirming you will not do any business with entities in those sanctioned areas at the risk of losing access to your bank account. For physical goods that’s pretty straightforward, but for online services, there’s more of a grey area, as people tend to move around. Nevertheless, there have been reports sanctions are now affecting users in Iran and Crimea, as Github has started to restrict the account of users who are registered in US sanctioned countries. Github is now owned by Microsoft, and large multinationals can’t just fly under the radar, and ignore rules and regulations. It all started from reports from users from Crimea and Iran, who are lost access to their Github …

KB-IDE Open Source IDE Supports ESP-IDF, Arduino, and Visual Programming for ESP32 Boards

KBIDE

We’ve previously written about MakerAsia when covering their KBX Extension case for Kidbright ESP32 educational board. The company has now launched a new product, but it’s not an hardware platform, and instead KB-IDE is an open IDE (Integrated Development Environment) ESP32 boards. The IDE is suitable whatever your level from kids getting started with supports visual programming, to Arduino programming, and even the official Espressif ESP-IDF framework for more experienced makers. The IDE comes with with a Board Manager, a Plugins System and works with any Arduino Library out of the box. Made with Vue.js framework, KB-IDE is open source with the code available on Github.  You can install a binary release, or build it from source for Windows, Linux, or Mac OS. Since it’s open source, it’s also expandable so makers can customize it, for instance by adding new architectures (AVR and ARM are already planned), new boards,  creating plugins and/or adding libraries. I’ve found KD-IDE to be quite …

SAUCS is a Search Engine for Security Vulnerabilities (CVE Database)

SAUCS MDM9206 CVE

Every so often we hear about critical security vulnerabilities in the news, but new ones are actually discovered daily, so it would be nice to have some sort of search engine to find out which known security vulnerabilities a given product or processor may have before purchasing it, or even more importantly starting a project. SAUCS does just that by having robots checking out the CVE update list, parsing the XML feed and formatting it. You can search for products or process, or subscribe to the vendors and products you want, and receive an email as soon as new changes as detected. I found out about SAUCS thanks to a comment from Thomas who pointed out the Qualcomm MDM9607 processor found in Quectel EC25 LTE module had a fairly long list of CVE (Common Vulnerabilities and Exposures) entries while using the default? firmware as shown in the screenshot above. Each CVE entry is ranked by its CVSS (Common Vulnerability Scoring …

Embedded Linux Conference & Open Source Summit 2019 Schedule

Embedded Linux Conference 2019 Schedule

In the last few years, I covered the Embedded Linux Conference and IoT Summit schedules since both were happening at the same time and in the same location. But the Linux Foundation have recently announced the Embedded Linux Conference will combine with the Open Source Summit, so the IoT Summit appears to have been phased out. The full schedule for the events taking place on August 21 – 23, 2019 at the Hilton San Diego Bayfront, USA, has also been released, so I’ll create a virtual schedule with some of the sessions most relevant to this blog. Wednesday August 21, 2019 11:30 – 12:05 – What’s New with U-Boot? by Simon Glass, Google LLC U-Boot is a widely used bootloader in embedded systems. Many users are unaware of the wide feature-set of U-Boot, particularly features added in the last few years. This talk aims to bring users (and prospective users) up to speed on the state of the art in …

Eclipse IoT Survey Report Reveals Arm & Linux Dominate, Security Concerns

Constrained devices Arm IoT

The Eclipse IoT Working Group has just released a report asking the global IoT developer community to share their perceptions, requirements, and priorities. And with over 1,700 individuals taking the survey between February and March 2019, the key findings are interesting: IoT drives real-world, commercial outcomes today. 65% of respondents are currently working on IoT projects professionally or will be in the next 18 months. IoT developers mostly use C, C++, Java, JavaScript, and Python AWS, Azure, and GCP are the leading IoT cloud platforms Top three industry focus areas remain the same as last year: IoT Platforms, Home Automation, and Industrial Automation / IIoT. MQTT remains the dominant IoT communication protocol leveraged by developers The Eclipse Desktop IDE is the leading IDE for building IoT applications The last point may be slightly biased because the survey was done by the Eclipse IoT Working Group, so most respondents were already familiar with the Eclipse IDE. Security concerns dropped slightly compared …

FOSSASIA 2019 Schedule – March 14-17

FOSSASIA 2019 Schedule

As its name implies, FOSSASIA is a Free and Open Source Software  event taking place every year in Asia, more specifically in Singapore. I first discovered it last year, and published a virtual FOSSASIA 2018 schedule last year to give an idea about the subjects discussed at the event. It turns out FOSSASIA 2019 is coming really soon, as in tomorrow, so I’m a bit late, but I’ll still had a look at the schedule and made my own for the 4-day event.  Thursday – March 14, 2019 10:05 – 10:25 – For Your Eyes Only: Betrusted & the Case for Trusted I/O by Bunnie Huang, CTO Chibitronics Security vulnerabilities are almost a fact of life. This is why system vendors are increasingly relying on physically separate chips to handle sensitive data. Unfortunately, private keys are not the same as your private matters. Exploits on your local device still have the potential to grant bad actors access to your screen …

A Tale of Many Divisions – Naive Prime Factorization Across a Handful of Architectures

Compiler Explorer Dissassembly

CNXSoft: Another guest post by blu where he looks at how a small piece of code involving divisions behaves on different architectures. Once upon a time (i.e. the other week) I was giving tips to my 5th-grader how to efficiently compute least common multiples, when it struck me I could do better ‒ I could write a prime factorizer that could be useful to the elementary-school-goers in this house, as well as to the people checking the formers’ homeworks. Moreover, a naive prime factorizer could show kids how computers would carry out algorithms taught in class. There was also a bit of curiosity involved ‒ last time I wrote a prime factorizer I was in high school, and the language was Applesoft BASIC, so 30 years later, armed with a modern C++ arsenal and a supercomputer (by late ‘80s standards), I wondered what one might come up with today, approaching the problem from first principle (sorry, no Euler today). The …

How to Migrate from Github to Gitlab

Github is by far the most popular web-based hosting service for version control using Git, but it’s not the only option as Gitlab and Bitbucket offer alternatives. If for whatever reasons, you feel the need to migrate from Github to another service, it’s actually quite easy, and I’ve tried it with Gitlab, which offers a very easy solution to import your code repositories from Github. First, you’ll need to sign-in to Gitlab. That part does not need explanation. The next step is to go to Settings->Account, and in the Social Sign-in section, connect Gitlab to your Github account. After logging in to your Github account, youl should be set. Now click on the + icon on the op of the web page, and select New Project. Click on the Import project tab, and import project from Github. You’ll be asked to input your Github password again, and be brouhgt to your list of repositories. Now you can simply click on …
