  • Philips Hue Bridge v2.1

    I recently bought a Hue Bridge to experiment a bit with Zigbee and 802.15.4. Following two posts for the hardware version 2.0 and some comments about the differences to version 2.1 I was able to get shell access on my 2.1 hardware.

    As there is up to now no complete guide I describe here, what I did:

    Opening the case is straigth forward. Just remove the two lower nubsis at the bottom and unscrew the two torx screws; then carefully unclip the bottom.

  • $10 HelTec CubeCell LoRa Board Features Cypress PSoC 4 MCU

    The board can be controlled with AT command, but it also supports Arduino programming in Windows, Mac OS, and Linux. You’ll find documentation and code samples on Github, as well as on Heltec’s own website.

    The company provides an example of battery life considering a connection with the LoRa gateway every 15 minutes. In this case, an 80mAh/3.7V battery would last for 3 months, but they did not mention in which mode they performed the calculation.

Firefox 70 review - the inversion point?

I am happy that Mozilla has found some of its old identity, the one before it tried to copypasta Chrome. The privacy message resonates well with all that's been happening lately. So perhaps it's difficult to convince the Average Joe about memory consumption and perceived speed and such, but "they gonna git yo data" argument might stir an odd photon or two in a brain somewhere. When it comes to privacy, Firefox definitely leads the field, and this is a great selling point. It's not everything of course, but the combination of a toned down message, the ability to change pretty much every setting, including the browser look & feel, do offer a sense of freedom in a world of diminishing liberties for consumers. Firefox 70 offers a nice bundle, and it might be the version that slowly brings the stray ones back to the fold. Hopefully. All in all, if you have reasons to like Firefox, version 70 should give you a dose of extra happiness. If you don't, it might be the version that makes you reconsider. From the most cheerful reviewer of software on the planet, goodbye. Read more

CentOS 6 Through CentOS 8 Benchmarks On Intel Xeon

Complementing the CentOS 8 benchmarks I did following the release of that Red Hat Enterprise Linux 8 rebuild in late September, here are tests going back further for showing the performance of CentOS 6, CentOS 7, and CentOS 8 all benchmarked from the same Intel Xeon Scalable server. These tests were done about a month ago albeit with all the hardware launches, new child, and other factors, only now getting to posting the data. These benchmarks are of CentOS 6, CentOS 7, and CentOS 8 with all available stable release updates for each as of early November (prior to TAA, JCC Erratum, and other more recent disclosures). This was done to look at how the performance of these CentOS releases compare that track RHEL6, RHEL7, and RHEL8 respectively. Additionally, for each operating system was also a secondary run when booted with mitigations disabled to also provide a look at the CentOS Linux performance with the various CPU security mitigations disabled.
