Friday’s news, still fresh… read it over at Compose Articles. Fresh MongoDB and PostgreSQL development versions on the road to production, MariaDB’s TX does Oracle and more. Enjoy.
It’s Friday and here’s the new NewsBits with database updates galore, malware in dependencies, a new DB based on MySQL, the latest Rust and Sublime Text and mmm… CloudEvents (not a conference (not yet at least)).
Did that NewsBits Thing so you can read about TiDB, a database in PHP, Code’s latest update and Rowhammer in your pocket.
What I write during my day job – Here’s my Friday Newsbits where you can find out about Redis getting native TLS, the other MySQL update, the latest Node.js 10 and Flask 1.0 and more. Do let us know if you enjoy it.
The day job gets me writing news of Friday and what a databasey news week. FoundationDB open sourced, MySQL 8 going GA… check it out in Compose’s NewsBits.
Recent writings from me
This weeks Newsbits where the bestest daily tool for PostgreSQL gets to 1,0, MySQL jumps some versions and Samba has a password problem.
Stunneling to Redis where we use a neat feature of Stunnel to make on demand secure connections to Redis.
And part of a series on connecting NodeJS to databases covering MongoDB, PostgreSQL and Elasticsearch.
Here’s my database-y, cloud-y, developer-y news round up for the week – It’s NewsBits on the big releases on the week and more.
Over at Compose, where I work, I do a Friday news roundup, and here is this weeks NewsBits. There’s stuff about Riak, Go, OmniDB and a fun thing about fake RAM chips.
An edifying weekend saw me looking at a whole load of ESP32 based boards – The WiPy 2.0, the Sparkfun ESP32 Thing and the Huzzah32… and in turn a whole set of MicroPython variants… MicroPython is a shrunk down Python 3 for embedded devices and it can fit in some pretty small spaces – there’s a version for the MicroBit even. Anyway, I wanted to find out if I could do a particular projects proof of concept using MicroPython. Let battle commence…
First up was – Pycom’s MicroPython for the WiPy 2.0 is well packaged and relatively complete; it includes RTC support and enough other drivers that I was able to build my proof of concept device. The VS Code integration was neatly done and so much more useful than previous attempts… But the board is literally just the processor. Supply power on the pins and bring your own USB or use their expansion boards. That was already bumping the costs up…. before I went further prototyping (as the rig was already syncing clocks, reading RFID cards and posting to REST endpoints) I thought I’d have a look around.
It’s a lovely little Feather board – I do like the Feather form factor and with the new Express boards bringing CircuitPython into play things look interesting. CircuitPython is Adafruit’s fork which tries to simplify the whole thing with embedded hardware where lots of physical features turn into code for particular boards and stop things being portable. Great idea. Turns out the Huzzah32 doesn’t have a CircuitPython port yet though… CircuitPython is an interesting fork but it needs a target board with a bit of WiFi. The Huzzah32 does have the USB and LiPoly support so theoretically it could run MicroPython… let’s try straight MicroPython on an ESP32…
Specifically, lets go back to MicroPython and run from the fork for ESP32. This was to run on the Sparkfun ESP32 Thing, which is a super practical hacking board at a decent price and complete with USB and LiPo battery support. It’s not a small board, but it’s easy to shoehorn in. Then there’s the current MicroPython for ESP32 – like pretty much every API for the ESP32 it’s a work in progress, but this work in progress hurt hardest when I found no RTC clock support in MicroPython at the moment.
The weird part is… writing the Python code was pretty plain sailing for this embedded environment, so I’m guessing it can only get better.
Meanwhile for the proof of concept project…. Heading back to the Arduino framework was no less fruitful. Again, missing RTC support lead the problem set. So I’m back on the WiPy 2.0 to finish the PoC and wondering if I really want to get all C++y to use the Espressif native tool chain. At least there’s be no lack of drivers…
But, and I didn’t think I’d say this…. but I cant wait for Python to harden up in the embedded space.
Here’s another little batch of database news I did at the day job…. enjoy.
