Arm Research Summit 2017 Streamed Live on September 11-13

The Arm Research Summit is “an academic summit to discuss future trends and disruptive technologies across all sectors of computing”, with the second edition of the even taking place now in Cambridge, UK until September 13, 2017. The Agenda includes various subjects such as architecture and memory, IoT, HPC, computer vision, machine learning, security, servers, biotechnology and others. You can find the full detailed schedule for each day on Arm website, and the good news is that the talks are streamed live in YouTube, so you can follow the talks that interest you from the comfort of your home/office. Note that you can switch between rooms in the stream above by clicking on <-> icon. Audio volume is a little low… Thanks to Nobe for the tip.

MINIX NEO Z83-4 Pro Mini PC Review – Part 2: Windows 10 Pro

MINIX launched NEO Z83-4 Cherry Trail mini PC last year, but the company has now launched NEO Z83-4 Pro, an updated version with a slightly faster Atom X5-Z8350 processor, Windows 10 Pro (instead of Home), and a a VESA mount kit. I’ve already checked the hardware in the first part of the review, so today I’ll report my experience with Windows 10 Pro. Windows 10 Home vs Windows 10 Pro My main computer runs Ubuntu 16.04, and I’m only using Windows 10 during reviews… But so far all other mini PCs I tried came with Windows 10 Home, and NEO Z83-4 Pro is my first Windows 10 Pro computer. So I had to educate myself, and Microsoft website has a comparison between the two versions of Windows 10. Windows 10 Pro supports all features of Windows 10 Home, plus the following: Security Windows Information Protection – Formerly Enterprise Data Protection […]

Linux 4.13 Release – Main Changes, ARM & MIPS Architectures

Linus Torvalds has just announced the release of Linux 4.13 and a kidney stone…: So last week was actually somewhat eventful, but not enough to push me to delay 4.13. Most of the changes since rc7 are actually networking fixes, the bulk of them to various drivers. With apologies to the authors of said patches, they don’t look all that interesting (which is definitely exactly what you want just before a release). Details in the appended shortlog. Note that the shortlog below is obviously only since rc7 – the _full_4.13 log is much too big to post and nobody sane would read it. So if you’re interested in all the rest of it, get the git tree and limit the logs to the files you are interested in if you crave details. No, the excitement was largely in the mmu notification layer, where we had a fairly last-minute regression and […]

Embedded Linux Conference & Open Source Summit Europe 2017 Schedule

The Embedded Linux Conference & IoT summit 2017 took place in the US earlier this year in February, but there will soon be a similar event with the Embedded Linux Conference *& Open Source Summit Europe 2017 to take up in Europe on October 23 – 25 in Prague, Czech Republic, and the Linux Foundation has just published the schedule. It’s always useful to find out what is being discussed during such events, even if you are not going to attend, so I went through the different sessions, and compose my own virtual schedule with some of the ones I find the most interesting. Monday, October 23 11:15 – 11:55 – An Introduction to SPI-NOR Subsystem – Vignesh Raghavendra, Texas Instruments India Modern day embedded systems have dedicated SPI controllers to support NOR flashes. They have many hardware level features to increase the ease and efficiency of accessing SPI NOR […]

Kingston Adds 4 GB & 8 GB Capacities to DataTraveler 2000 Encrypted USB Flash Drives with Keypad

Kingston DataTraveler 2000 is a USB 3.0 flash drive that stores files with hardware based AES-256 encryption, and to make sure nobody can access those, it’s also protected with a pin code thanks to a keypad on the flash drive itself. That’s news to me, but the devices have been selling since early 2016 with 16 to 64GB capacities, and you’ll find them on Amazon for $127 and up. However, since such high security USB flash drives are mostly used for confidential information by enterprises and governments (it’s FIPS-197 compliant), some company’s customers may have complained that 16 to 64GB storage is a bit too much for confidential data, with recent top secret documents leaks or IP thefts, so Kingston has just announced smaller 4GB and 8GB versions of the drives. Those drives are OS agnostic with encryption occurring inside the drive, and seen buy your computer or other hardware […]

Installing Let’s Encrypt Free SSL/TLS Certificate in 2 Minutes with Certbot, Spending Hours Making it Work with Cloudflare

I’ve been using an SSL certificate to the download subdomain of this blog running ownCloud for about 2 years, but recently my free StartSSL certificate expired, and I had troubles to renew it, and I also received an email from Google telling me that “Starting October 2017, Chrome (version 62) will show a “NOT SECURE” warning when users enter text in a form on an HTTP page, and for all HTTP pages in Incognito mode”. So I decide to use free LetsEncrypt SSL/TLS certificates to replace the one in the download subdomain, as well as this main blog. Such SSL/TLS certificates are also very useful for the IoT gateways many of use have started using, and I found it’s even simpler than install a self-signed certificate, so there’s no reason to use those anymore. The easiest way to install Let’s Encrypt certificate is by using Certbot with instructions for various […]

Infineon Claims to Have Implemented Post-Quantum Cryptography on a Contactless Security Chip

Today we protect systems, data, and communication using encryption keys of various lengths together with secure algorithms, and after a quick check, I found out banking websites are using 128-bit to 256-bit keys for secure (TLS v1.2) communication, and my Linux system is using a 4096-bit RSA key for secure communication over SSH. According to an Infineon press release, such key length are suitable for secure communication today, and current computer do not have sufficient processing power to break encryption, but with the advance of Quantum computer, even RSA-2048 keys won’t be secure, which means in 15 to 20 years all data encrypted (and stored) today with such keys would theoretically be accessible in the clear. That’s why the company has been working on next-generation post-quantum cryptography (PQC), and recently demonstrated the first PQC implementation on a commercially available contactless security chip, as used for electronic ID documents. The company […]
