u-blox SARA-R10001DE LTE Cat 1bis Module integrates an eSIM with Multi-IMSI and eUICC support

u-blox has introduced the SARA-R10001DE, an LTE Cat 1bis module with integrated eSIM featuring multi-IMSI technology and eUICC functionality. The module is pre-provisioned with Wireless Logic’s Conexa IoT Network SIM profiles for global IoT deployments. The eSIM supports OTA using Remote SIM Provisioning, allowing the module to switch between multiple stored SIM profiles to connect to the best available network. Multi-IMSI technology allows eSIMs to store multiple International Mobile Subscriber Identity (IMSI) profiles, enabling dynamic network switching for uninterrupted connectivity. eUICC functionality, based on the GSMA standard, facilitates OTA updates and profile management, simplifying operator switching and ensuring global compliance. Although SARA-R10001DE is u-blox’s first LTE Cat 1bis module with an embedded SIM (eSIM), we previously covered the u-blox LEXI-R10 LTE Cat 1bis module and associated evaluation kit, as well as Cavli C17QS Cat 1bis module built around the Qualcomm QCX217 microcontroller. u-blox SARA-R10001DE module specifications: LTE module – SARA-R10001DE […]

Barebone Intel Celeron 2955U or Pentium 3805U fanless industrial mini PC goes for $60 (Promo)

Low-cost Intel Celeron 2955U fanless mini PC

If you’re in need of a low-end, cheap x86 platform you’re in luck since XCY is selling the X46G industrial fanless mini PC powered by an Intel Celeron 2955U Haswell processor or a Pentium 3805U Broadwell CPU for just about $60 as a barebone system, or around $74 with 4GB of RAM, a 64GB SSD, and a WiFi module as part of a Black Friday 2024’s promotion. It’s even cheaper in some other shops, as we’ll see below. Both CPUs have been discontinued since 2021, and nobody should use those in a desktop system unless you are of the very patient type. However, if you want to run some lightweight Windows or Linux application(s), make use of RS232 ports for industrial control, set up a Full HD HTPC, configure a dual GbE server, or need to run FreeDOS or similar x86-only operating systems, those ultra-cheap Intel mini PCs might prove […]

GEEKOM Mini Air12 Lite Review – Part 3: Ubuntu 24.04 on a low-cost mini PC

GEEKOM Mini Air12 Lite Ubuntu 24.04 review

We have already checked the hardware of the GEEKOM Mini Air12 Lite mini PC in the first part of the review, before testing the low-cost Intel Processor N100 mini PC with its 8GB RAM and 256GB SATA SSD running Windows 11 Pro in detail in the second part. We’ve now had time to test the GEEKOM Mini Air12 Lite with Ubuntu 24.04 in the third and final part of the review. We’ll test the features in Linux, run some benchmarks, evaluate storage and network performance, play some 4K and 8K videos in YouTube playback, perform a stress test to check its thermal design, and finally measure the mini PC’s fan noise and power consumption. We’ll also compare the results in Linux to the earlier GEEKOM Mini Air12 mini PC with the same CPU, but better specs and a higher price. A challenging Windows 11 / Ubuntu 24.04.1 dual boot installation […]

Mitigating a DoS attack with GoAccess and Cloudflare

In this off-topic post, I’m going to discuss some behind-the-scenes “fun” that may happen when managing the web server used to host the CNX Software website. From time to time, the server becomes unreachable, but I can still access its console, and notice a very high CPU load (over 100) on a VPS with four cores, while the CPU load is typically 0.5 to 2 under normal circumstances. That’s usually due to a DoS (denial of service), DDoS (distributed denial of service), or some bug I can’t identify. An easy way to solve this issue is to log in to Cloudflare and set the “Under Attack Mode” to on. It will show all visitors a JavaScript challenge the first time they visit the website, and the CPU usage typically drops back to normal level within a minute or so. That means I can access my website and so do regular […]

Black Friday and Cyber Monday 2024 – International deals and coupons

While Black Friday and Cyber Monday used to be a US-only event, it changed many years ago, and we’ve been writing about international Black Friday and Cyber Monday deals and coupon codes since 2014, since a large portion of our audience cannot benefit from promotions on Amazon’s Black Friday and Cyber Monday events that will take place from November 21 until December 2 this year. So I’ve gathered some international Black Friday and Cyber Monday 2024 deals and discount coupon codes from relevant manufacturers and popular online stores such as Aliexpress, Banggood, and others. Aliexpress Black Friday and Cyber Monday event Aliexpress’ Black Friday and Cyber Monday 2024 event has already started. There are three periods: Nov 19-21 PST – Warm Up event where users can find and add items to the cart before purchasing during the main event. Nov 22-30 PST – “On Sale” event with discounts up to […]
