Instead, I’m breaking in a new site at Codepope.dev1. There’s already a post up (with code) about the PyPortal. So, maybe see you there. It’s going to be a work in progress (no comments yet), but see you there - you can get in touch through Twitter (@codepope) if you want.https://codepope.dev/post/2018/11/levelling-the-word-clock/Sun, 18 Nov 2018 16:42:02 +0000https://codepope.dev/post/2018/11/levelling-the-word-clock/Cyntech do a word clock - an 8x8 array of neopixels, a set of acrylics to make a box and stencils for the words and space to fit in a pi zero or pi 2/3 inside. It’s been built here for a while and suffering from random light shows on the display and dropping the WiFi. Well the light shows were down The the fact that the neopixels work at 5v but the Pi data line is a beefy 3.https://codepope.dev/post/2018/11/fireworks-like-a/Sun, 04 Nov 2018 17:09:48 +0000https://codepope.dev/post/2018/11/fireworks-like-a/So in the background, I’ve been playing around with digital fireworks on various LED displays, mostly on the Raspberry Pi Zero with PS3 controllers and well that was going on with various levels of success and then I took a break from that approach. I noticed that I had an ESP32 Feather and a 3.5" Featherwing touch screen. What the heck, I said and a few hours later… So touch and out come the particles….https://codepope.dev/post/2018/10/all-change-to-mongodb/Sat, 27 Oct 2018 15:38:16 +0000https://codepope.dev/post/2018/10/all-change-to-mongodb/If you follow me on Twitter, then you’ll know that I’m in the process of leaving IBM who acquired Compose (who were MongoHQ) some years back. It was a super-fun ride, but things change and after a while you need to move on. And the best moving on is the moving on where you get to do something even more interesting… So, my next stop is, in a delightful circular fashion, MongoDB Inc where I’ll be hitting the buttons on keyboards in interesting ways to get them to exude the rich taste and delightful aroma of steeped and chilled content (mmm… brewed overnight, every night).https://codepope.dev/post/2018/09/elsewhere-newsbits-on-java-11/Fri, 28 Sep 2018 16:40:53 +0000https://codepope.dev/post/2018/09/elsewhere-newsbits-on-java-11/As is my way, I’ve been writing elsewhere for a living among other things and here’s the latest NewsBits I gathered up…. Java 11 arrives with long term support and warnings. Refactoring .then() added to Microsoft’s TypeScript. Ready for PostgreSQL11, PostGIS 2.5.0 released. Your own database Arnie: pg_terminator kills PostgreSQLconnections. Make SQLprettier with sqlfmt. Read about CrimsonDB’s adaptive key/values. Kubernetes gets a TLS bootstraping update. And Finally … How to scan a Rocket.https://codepope.dev/post/2018/09/elsewhere-newsbits-redis-5-rc-5/Fri, 07 Sep 2018 16:29:07 +0000https://codepope.dev/post/2018/09/elsewhere-newsbits-redis-5-rc-5/I’ve been doing my usual Friday news gathering for the day job and that means here is todays NewsBits…. Here’s what’s in it: Redis 5.0 gets a new release candidate and controversy. Updates for older MongoDB versions. A guide to analyzing slow MongoDB queries. Making MySQL’s shell shine. Google open up Dataset Search. Firefox 62 lands, as does the new ESR release. HTTP2 support no longer experimental in Node 10.10. VS Code gets a new Settings UI.https://codepope.dev/post/2018/09/elsewhere-newsbits-end-of-august-edition/Mon, 03 Sep 2018 17:30:18 +0000https://codepope.dev/post/2018/09/elsewhere-newsbits-end-of-august-edition/In the most recent NewsBits (NewsBits at Compose.com’s Articles) there’s some minor DB and driver updating, a DB that branches like git, a fresh Vault, what happens to SSDs when they meet database write loads, the new Go 1.11 (and 2 drafts) and… oh yeah who wants to see round corners? (Apologies for the lateness… I’ve been playing with MicroPython, CircuitPython, ESP32s, ESP8266s and a selection of tiny light emitting things….https://codepope.dev/post/2018/08/elsewhere-newsbits-for-august-24th/Sat, 25 Aug 2018 09:15:16 +0000https://codepope.dev/post/2018/08/elsewhere-newsbits-for-august-24th/As is my Friday wont, I wrote up NewsBits for Compose but then things move fast… since that was published Go 1.11 has landed… Really looking forward to using that in anger (good anger, not “damn computer” anger). (Today’s a HackWimbledon day and I’ll be there possibly assembling a RasPad and Featherwings….) Elasticsearch 6.4 now has an alias (type) and much more. There was a bit of controversy around Redis and licensing.https://codepope.dev/post/2018/08/elsewhere-newsbits/Sat, 11 Aug 2018 06:42:25 +0000https://codepope.dev/post/2018/08/elsewhere-newsbits/Here’s my regular Friday database and developer news from Compose: • PostgreSQL stable updates all round. • And there’s a new PostgreSQL 11 beta. • How well does PostgreSQL work with a GPU? • Redis 4.0.11 is all about timing. • While Redis 5.0 RC4 hardens its streams. • JanusGraph 0.3.0 edges the graph database forward. • A first update for MongoDB 4.0. • CouchDB 2.2 makes storage pluggable. • Google’s Dart 2 is stable and released.https://codepope.dev/post/2018/08/kindle-hacking-and-clocking/Mon, 06 Aug 2018 20:49:48 +0000https://codepope.dev/post/2018/08/kindle-hacking-and-clocking/There’s a super little Instructable on how to make a Literary clock using a Kindle. Well, I happened to have an old school original Kindle 3 about and dived it. Some observations…. The jailbreaking materials for the Kindle are functional but there’s so many images out there its easy to see why people can get confused. The USB/Wifi Networking hack is pretty good to work with when you’re doing USB only, but I wasn’t sold on Wifi configuration, so I stuck with USB and the joy of self-assigning IPs.https://codepope.dev/post/2018/08/rebooting-codescaling-keyboard-kickoff/Sat, 04 Aug 2018 12:52:35 +0000https://codepope.dev/post/2018/08/rebooting-codescaling-keyboard-kickoff/I’ve not been blogging much here, but thats going to change. Fresh lick of theme, and… we’re off. First up, this Ortho-linear keyboard from OLKB. I have a distinct keyboard fetish and I don’t think it’ll be every satisfied. Always looking for something different and this OLKB Plank kit seems to have tickled every spot. The Ortho-linear layout puts everything on a grid, and has no proven benefits but it does feel nice to type on in terms of finger positioning.https://codepope.dev/post/2018/05/a-little-late-but-heres-last-weeks-news/Sun, 27 May 2018 18:08:55 +0000https://codepope.dev/post/2018/05/a-little-late-but-heres-last-weeks-news/Friday’s news, still fresh… read it over at Compose Articles (or here and below in the archive). Fresh MongoDB and PostgreSQL development versions on the road to production, MariaDB’s TX does Oracle and more. Enjoy. A first release candidate for MongoDB 4.0. PostgreSQL 11 enters beta. Locking up? PostgreSQL and MySQL locks. MariaDB TX goes for Oracle enterprises. Database down time at Wikipedia. Containerd’s Kubernetes integration goes GA. Bash Bash now with Bash Alpha 5.https://codepope.dev/post/2018/05/that-friday-feeling/Fri, 11 May 2018 17:33:35 +0000https://codepope.dev/post/2018/05/that-friday-feeling/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)). Updates for PostgreSQL, RabbitMQ, etcd and Scylla. “Cloud native” MySQL-based RadonDB appears. CloudEvents to bring serverless systems together. Looking to be big in enterprises - Firefox 60. Python and Node malware in dependencies. Ligatures and HiDPI support in Sublime Text.https://codepope.dev/post/2018/05/this-fridays-bits/Fri, 04 May 2018 16:39:14 +0000https://codepope.dev/post/2018/05/this-fridays-bits/Did that NewsBits Thing so you can read about TiDB, a database in PHP, Code’s latest update and Rowhammer in your pocket. Welcome to NewsBits where you’ll find the database, security, and developer news from around the net for the week ending May 4th 2018: TiDB gets to version 2.0. An update comes to MariaDB 10.0. FoundationDB’s progress report is in. PHP fans may want a SleekDB.

FoundationDB open sourced, MySQL 8 going GA… check it out in Compose’s NewsBits (Archived and below). Apple open sources FoundationDB. MySQL 8 gets officially released. Security fixes for Elasticsearch machine learning. Titus from Netflix is open sourced. Oracle releases polyglot GraalVM. Atom gets better for pairs. Code deanonymization gets smarter. And finally, make an analog noise with open source.https://codepope.dev/post/2018/03/some-bits-of-codescaling/Sun, 18 Mar 2018 14:39:14 +0000https://codepope.dev/post/2018/03/some-bits-of-codescaling/Recent writings from me This weeks Newsbits (archive and below) where the bestest daily tool for PostgreSQL gets to 1,0, MySQL jumps some versions and Samba has a password problem. Stunneling to Redis (archived) where we use a neat feature of Stunnel to make on demand secure connections to Redis.

Anyway, I wanted to find out if I could do a particular projects proof of concept using MicroPython.https://codepope.dev/post/2017/08/another-newsbits/Sun, 20 Aug 2017 22:43:22 +0000https://codepope.dev/post/2017/08/another-newsbits/Here’s another little batch of database news I did at the day job…. enjoy.

It’s a board with a 40 pin Pi header, USB connector and software for Pixel, Linux, OSX and other operating systems which lets you drive it like a Pi’s GPIO header. There’s just so many neat things you can do with this card. It’ll let you hang that neat Pi Hat off your PC simply. It’ll let you double up your Pi’s GPIO capability.https://codepope.dev/post/2016/12/here-comes-2017-and/Wed, 28 Dec 2016 18:03:42 +0000https://codepope.dev/post/2016/12/here-comes-2017-and/Well, 2017 is days away and it’s time to make some decisions about this blog. The options are simple, shut it down and make a new personal blog in the style of Codescaling, or carry on here just reworking the site as my personal space. To be honest the latter option seems to be cheapest and most effective, so…. Codescaling is deaded, long live Codescaling. I’ll be working on a new about page along with some new posts about what’s been in my recent makery builds (Z80 boards, Orange Pi, Linkit 7655 and more) and HackWimbledon bits and crosspostings from the day job at Compose and… well, we’ll see.https://codepope.dev/post/2016/08/from-my-other-output/Sat, 20 Aug 2016 10:56:32 +0000https://codepope.dev/post/2016/08/from-my-other-output/I’ll be posting some of my regular items I do elsewhere here from now on and…. one thing I write every Friday us Compose’s Little Bits. Here’s what’s in the latest: Postgres-BDR goes 1.0, MongoDB updates the stable and development branches, a look at Hexastores, Sophia’s key/value storage gets rows, Go goes 1.7, PowerShell goes open source, Github makes page publishing easier, GnuPG gets fixed randomness, Apple talks Black Hat and the world of Wikipedia in a Wikiverse.https://codepope.dev/post/2015/11/just-a-note/Sun, 15 Nov 2015 20:14:44 +0000https://codepope.dev/post/2015/11/just-a-note/Yes, it has been quiet here. Things have been busy elsewhere and I’m in the process of reworking what and how I’ll be populating Codescaling. I’m currently leaning to talking more about the scaled down world, small systems and working with them. But its up in the air. So, reader, what do you want?

For Node.js, it was the reunification with io.js under the Node.js Foundation, which was officially launched under the Linux Foundation’s umbrella. The Node.js and io.js technical development is now driven by a technical committee and hopefully this will all work out well for all.https://codepope.dev/post/2015/05/developer-catchup-rust-1-0-and-node-reunification/Sun, 17 May 2015 20:57:05 +0000https://codepope.dev/post/2015/05/developer-catchup-rust-1-0-and-node-reunification/First up, Rust has reached version 1.0, though this is an announcement that was hardly unexpected. It has a lot to live up to given the Rust web site goes for such unloaded language as “blazingly fast, prevents nearly all segfaults, and guarantees thread safety”. The real test for Rust, at least for me, is how well Servo, Mozilla’s browser written in Rust and the application Rust was created with in mind.https://codepope.dev/post/2015/05/arduino-ide-now-boarding-for-all/Sun, 10 May 2015 21:46:25 +0000https://codepope.dev/post/2015/05/arduino-ide-now-boarding-for-all/The Arduino IDE is heading into a rather neat consolidation of the numerous Arduino inspired boards out there. The introduction of a mechanism, in version 1.6.2, to allow people to plug their boards into the IDE easily is starting to snowball. To understand why this is important, before 1.6.2’s release if you had a custom board and the tools to make it work with the IDE, then to install them involved copying files into directories, editing files and crossing fingers (and being disappointed often).https://codepope.dev/post/2015/04/making-catchup-node-0-10-6-pi-power-arduino-ide-and-adapting-esp8266s/Mon, 06 Apr 2015 10:30:13 +0000https://codepope.dev/post/2015/04/making-catchup-node-0-10-6-pi-power-arduino-ide-and-adapting-esp8266s/Node-RED 0.10.6: Nick O’Leary has announced Node-RED 0.10.6 with various changes to the editor, nodes and API. If you don’t know Node-RED, it’s a rather graphically splendid way of wiring the internet of stuff and stuff in general together - I did a few bits with it on here. With this release, there’s also a new command line administration tool for Node-RED so you can control nodes without having to restart the entire process….https://codepope.dev/post/2015/04/developer-catchup-redis-3-0-0-es5to6-atom-pairs-rust-and-coherent/Mon, 06 Apr 2015 10:17:58 +0000https://codepope.dev/post/2015/04/developer-catchup-redis-3-0-0-es5to6-atom-pairs-rust-and-coherent/Redis 3.0.0: Antirez (Salvatore Sanfillippo) brought us Redis 3.0.0 on April 1st (and I salute him for ignoring the worst day on the Internet by doing real things). The big thing with 3.0 is clustering, better smarter clustering that is, out of the box and good enough scalability and fault tolerance for many use cases. It’s a big jump, and it may take some iterations to nail it down but its worth it for the usefulness that Redis represents to a system architect.https://codepope.dev/post/2015/03/disque-tiny-javascript-esp8266-notes-tails-gcc5-and-go-developer-catchup/Mon, 23 Mar 2015 10:24:50 +0000https://codepope.dev/post/2015/03/disque-tiny-javascript-esp8266-notes-tails-gcc5-and-go-developer-catchup/Disque: Antirez ,the man behind the splendid Redis in-memory key/value store has been working away on a new message broker called Disque. He’s not released it as yet, but he is giving status updates on his progress and thinking. Redis gets used a lot as a message queue and Disque, developed by gutting then rebuilding a Redis fork, is designed with a focus on that use case. There’s plenty of message queue platforms out there, but Antirez has a good record on delivering so this is very much one to keep tabs on.https://codepope.dev/post/2015/03/snippets-grpc-ipython-llvm-pi-trees-and-juice/Mon, 02 Mar 2015 10:58:34 +0000https://codepope.dev/post/2015/03/snippets-grpc-ipython-llvm-pi-trees-and-juice/gRPC: Google, doing it’s whomp-here’s-a-“standard” thing, has just announced an open sourced remote procedure call framework called gRPC. With libraries for seven languages (C, C++, Java, Node.js, Python and Ruby are done - ObjC, PHP and C# coming), gRPC gets you to use Protocol Buffers to define the end points and serialisation and the libraries then use HTTP/2 to communicate exploiting the bidirectional streaming and multiplexing. There’s an new alpha of a version 3.https://codepope.dev/post/2015/02/numberwang-with-linux-4-0-rc1/Mon, 23 Feb 2015 10:22:31 +0000https://codepope.dev/post/2015/02/numberwang-with-linux-4-0-rc1/It was that 3.0 version change which woke people up from the Linux 2.x problem, where scripts assumed Linux versions began with a 2 and, lets be honest, it wasn’t really a problem. If you have scripts which are assuming 3.x version numbers on your Linux builds, find the person who wrote them and sit them down for a “conversation” because there’s no way that that kind of assumption is excusable after only four years.https://codepope.dev/post/2015/02/snippets-javascript-node-git-http2-and-regexps/Mon, 16 Feb 2015 10:27:49 +0000https://codepope.dev/post/2015/02/snippets-javascript-node-git-http2-and-regexps/In this Snippets, 6to5 becomes Babel, Node.js 0.12 on Pi, Git 2.3, HTTP2 explained and regular expressions from chained methods. Node.js 0.12 on a Pi - If you’re trying to build Node.js on your older Raspberry Pi, you may have problems. Not now - Thanks to Conor O’Neill who has built Node.js getting around a problem with identifying the version of ARM processor by… applying some patches from io.js. You can download the built version from his blog… which will save you many hours of build time.https://codepope.dev/post/2015/02/docker-1-5-and-node-js-foundations/Wed, 11 Feb 2015 10:41:20 +0000https://codepope.dev/post/2015/02/docker-1-5-and-node-js-foundations/Back in December we saw two community splits, one in the Docker community and one in the Node.js community. It’s time to look back at both those splits. Docker 1.5 just landed with IPV6 support, read only containers, a stats API and CLI commands for streaming results and the ability to specify what Dockerfile to use when building. Good updates. Now, the other bits - There’s also an “Open Image Spec” which isn’t so much a spec as a formal declaration of whats currently implemented.https://codepope.dev/post/2015/02/developer-catchup-new-node-profanity-oh-my-git-knightmares-bad-docs-and-go-tracing/Sun, 08 Feb 2015 12:54:48 +0000https://codepope.dev/post/2015/02/developer-catchup-new-node-profanity-oh-my-git-knightmares-bad-docs-and-go-tracing/Node.js 0.12 has arrived with many long gestating changes now available. Io.js has a lot of these in already and a more up to date V8 engine for JavaScript, but if you’re sticking with Node.js releases, this is the biggy. Better more sensible streams, more HTTP sockets and keepalive, a new round robin clustering system and initial support for ECMAScript internationalisation. No, don’t go flipping your production system over to this right now, but do give it a go on your test/staging systems… it’s the future y’know.https://codepope.dev/post/2015/02/raspberry-pi2-already/Mon, 02 Feb 2015 12:03:26 +0000https://codepope.dev/post/2015/02/raspberry-pi2-already/It seems like less than a year ago when Eben Upton told Ars Technica that the Raspberry Pi Foundation was “a year or two away from thinking about” building new hardware. In less than a year, we’ve had the Model B+, the Model A+ and now, as a “Well-actually-we’ve-been-thinking-about-it-lots”, here’s the Raspberry Pi 2(archive). The good? It’s a quad core 900Mhz A7 ARM chip, it’s got 1GB of RAM and it looks just like a Raspberry Pi B+.https://codepope.dev/post/2015/01/making-catchup-6502-home-computer-trinket-mouse-beaglebone-io-manga-screen-and-picore-linux/Tue, 27 Jan 2015 21:16:32 +0000https://codepope.dev/post/2015/01/making-catchup-6502-home-computer-trinket-mouse-beaglebone-io-manga-screen-and-picore-linux/And it’s another catchup as the world whizzes by… Cool 6502 Builds: Dirk Grappendorf has built a lovely looking 6502 based microcomputer but more importantly takes you step by step through the entire build process from generating the clock to getting Basic running on it.

We talked about it at the end of last year. Well, now there’s something tangible - a 1.0.0 in development release. What thats means is, top of the list, ES6 support with generators, templates and new string methods and more. Boom, huge improvement in JavaScript for developers living the Node thing.https://codepope.dev/post/2015/01/esp8266-little-board-lotta-wi-fi/Mon, 12 Jan 2015 19:12:10 +0000https://codepope.dev/post/2015/01/esp8266-little-board-lotta-wi-fi/An ESPtoy (the ESP8266 is the little blue board) from RaysHobby.net. Lots going on with the intriguing ESP8266 board. Coming out of China with no english documentation, this tiny board has the brains to run Lua and connect to WiFi, manage some GPIO and all it takes is… a lot of fiddling. But for $2 on ebay, you can get hacking the firmware, flashing exisitng firmwarefrom Windows like nodemcu (thats the one with the lua) or just have fun running it as a serial controlled Wi-Fi adapter.https://codepope.dev/post/2015/01/raspberry-pi-b-gets-its-grove-on/Wed, 07 Jan 2015 23:01:13 +0000https://codepope.dev/post/2015/01/raspberry-pi-b-gets-its-grove-on/Raspberry Pi’s are great little Linux devices but they have plenty of limitations when it comes to comes to wiring up to the analog world or just behaving like a micro-controller. There’s been various attempts to weld Pi and Arduino together (I have some) like the Dexter Industries’ BrickPi that plugs you into the Lego bricosystem or their Arduberry which brings Arduino shield connectors out the top of the board.https://codepope.dev/post/2015/01/os-xs-hypervisor-snabbt-js-animation-and-nim/Tue, 06 Jan 2015 09:42:56 +0000https://codepope.dev/post/2015/01/os-xs-hypervisor-snabbt-js-animation-and-nim/Did you know Mac OS X 10.10 had a hypervisor framework? No, me neither, but it does and that means you can do things with hypervisors without the need for kernel extensions and stuff.

A group of core contributing developers have lost patience with Joyent, the developmental home of Node.js, and have set out to accelerate the development of the Async-JavaScript server side platform. This is the world of open source where people can vote with their time and effort. It’s easy to see both sides of the fork.https://codepope.dev/post/2014/11/developer-catchup-go-libraries-easy-charts-tumblr-frameworks-zsh-secrets-and-secret-android-compilers/Fri, 21 Nov 2014 12:16:41 +0000https://codepope.dev/post/2014/11/developer-catchup-go-libraries-easy-charts-tumblr-frameworks-zsh-secrets-and-secret-android-compilers/Facebook Go: When you develop a lot in Go, you make a lot of libraries and tools in Go.

The cut-down Pi now has microSD and a 40 pin GPIO to match the B+. It still lacks the features that made the ODROID/W so interesting – LiPo battery support and real time clock on board. It does retain one thing from the Model A, the question of who’s it actually for.https://codepope.dev/post/2014/11/developer-catchup-freebsd-at-21-meteor-at-1-0-tunnels-disklessness-neurons-and-68008s/Sun, 02 Nov 2014 17:35:05 +0000https://codepope.dev/post/2014/11/developer-catchup-freebsd-at-21-meteor-at-1-0-tunnels-disklessness-neurons-and-68008s/This article was imported from the original CodeScaling bloghttps://codepope.dev/post/2014/10/developer-catchup-poodle-tails-docker-redis-and-more/Sun, 19 Oct 2014 14:39:13 +0000https://codepope.dev/post/2014/10/developer-catchup-poodle-tails-docker-redis-and-more/POODLE yips: In what was a glorious nail in the coffin of SSLv3, the POODLE vulnerability(PDF) made sure no one would trust SSLv3 again. The simple fix is to turn off SSLv3 where its used. The bug itself is bad in terms of cryptography, in that it gives an attacker a route to completely decode a stream that has been encrypted, but in practice its not as bad because the attacker has to be a man in the middle to get started.https://codepope.dev/post/2014/10/making-catchup-1sheeld-codebender-odroidw-beans-metawear-and-more/Fri, 10 Oct 2014 18:02:25 +0000https://codepope.dev/post/2014/10/making-catchup-1sheeld-codebender-odroidw-beans-metawear-and-more/First of all a catchup on some of my making. I presented a short talk at Oggcamp 2014 on using the 1Sheeld with an Android phone to make experimenting with Arduino much simpler. The 1Sheeld sits on Arduino’s serial ports and using Bluetooth, talks to an Android phone app. The app is able to emulate a whole range of devices, like keypads and LEDs, and sensors, such as gyroscopes and barometers, and act as a proxy to web services like Twitter and Facebook.https://codepope.dev/post/2014/09/developer-catchup/Sun, 28 Sep 2014 12:22:46 +0000https://codepope.dev/post/2014/09/developer-catchup/Bashed: So the Bash bug is out there and real. These quick notes are still valid. The point is that this hideous feature (really, exporting function definitions through environment variables) is horrid and leaky by design and it’s only this bug in how that feature is implemented thats bringing it to the fore. CGI scripting, Qmail, some SSH and DHCP services are all potentially vulnerable, so patch away but be prepared to patch again because the lid is off this can of worms.https://codepope.dev/post/2014/09/developer-catchup-html5-nears-rust-heads-towards-1-0-and-playgrounds-examined/Sun, 21 Sep 2014 10:10:40 +0000https://codepope.dev/post/2014/09/developer-catchup-html5-nears-rust-heads-towards-1-0-and-playgrounds-examined/HTML5 getting closer: Over at the W3C the HTML5 spec has got close with the publication of the Proposed Recommendation of HTML5.

Simply put it allows a number of Arduino-style microcontrollers to be chained together over CAT5 cable with that cable delivering power, using a passive Power over Ethernet mechanism, and communications, using RS-485. This could be incredibly useful in creating a large area sensor net (current max, 32 boards) as it can stretch for up to quarter of a mile and there’s no need for power sockets along the entire length apart from where you inject the power.https://codepope.dev/post/2014/08/making-catchup-the-odroid-w-and-vu-bbb-gpio-and-tutorials/Sat, 09 Aug 2014 12:18:20 +0000https://codepope.dev/post/2014/08/making-catchup-the-odroid-w-and-vu-bbb-gpio-and-tutorials/ODROID-W: Hardkernel are more known for their Exynos based single board computers which pack quite a punch in a small space - enough that a meaty heatsink is needed. But their latest product eschews the Exynos chippery for a Broadcom chip, the same chip as the Raspberry Pi. The ODROID-W is apparently the result of a wearable research project which saw Hardkernel minimise the Pi design down to a wearable module.https://codepope.dev/post/2014/07/making-catchup-pi-gameboys-free-routing-easy-iot-service-and-a-robot-dinosaur/Sun, 27 Jul 2014 12:37:09 +0000https://codepope.dev/post/2014/07/making-catchup-pi-gameboys-free-routing-easy-iot-service-and-a-robot-dinosaur/Two Gameboy-a-likes: There seems to have been a little resurgence in the idea of emulating the classic Gameboy.At the start of the month, Adafruit introduced the PiGrrl which used a 3D printed case, a hacked up SNES style controller, a Pi and an Adafruit TFT display as the screen.

No change at the core, it’s the same 700mhz Broadcom chip with 512MB RAM, but it’s all changes outside. There’s a new USB/Ethernet chip, 4 USB ports, composite video pushed into the 4pin audio connector, reworked power handling and a 40 pin GPIO port. The latter is most likely to generate physical incompatibility though the layout changes mean no current cases will work. There’s more information over at Adafruit’s B+ page.https://codepope.dev/post/2014/07/catchup-new-pi-mearm-javascript-docker-goes-big-harder-dart-breach/Sun, 13 Jul 2014 17:54:16 +0000https://codepope.dev/post/2014/07/catchup-new-pi-mearm-javascript-docker-goes-big-harder-dart-breach/Hot Pi: First up, a hot rumour via Hackaday is that there’s a Raspberry B+ with 4 USB ports, no composite, a 40 pin GPIO port and other changes… is this real? We shall see, but the Pi has been aching for an update and even if this isn’t it, there’s a gap to be filled.

Apart from this being a rapid arrival for a major new release, the announcement notes that they aim to get future updates heading out within 24-48 hours of release. There’s a new versioning system too, so this is Cento 7.https://codepope.dev/post/2014/07/maker-catchup-beaglebone-gsm-basestation-pi-screenkeyboards-tiny-clocks/Sun, 06 Jul 2014 11:49:51 +0000https://codepope.dev/post/2014/07/maker-catchup-beaglebone-gsm-basestation-pi-screenkeyboards-tiny-clocks/Want to be your own GSM Base Station? This article will show you one way, though before you get too excited you’ll need a Ettus USRP B200 which starts at £495, or some other RTLSDR rig. This isn’t a cheap venture but the article steps through bringing the BBB together with the base station and adding the call handling and routing through OpenBTS. At the other end of the scale, Hackaday pointed to this tiny bubble clock project which uses the old-school LEDs which have recently reappeared on the market and a MSP430 microcontroller to create a perfboard based clock.https://codepope.dev/post/2014/07/developer-catchup-docker-1-1-0-rust-0-11-0-python-2-7-8-and-dropbox-go-libraries/Sun, 06 Jul 2014 11:08:46 +0000https://codepope.dev/post/2014/07/developer-catchup-docker-1-1-0-rust-0-11-0-python-2-7-8-and-dropbox-go-libraries/Docker 1.1.0: The first post 1.0 update for Docker is in and Docker 1.1.0 now has a .dockerignore mechanism for ignoring file changes, containers that now pause when a commit it happening (rather than messing them up), container log tailing, the ability to feed tar archives to docker build and other changes which should make life a bit easier and more predictable.

The 1.0 release and changes are broken down in a blog posting, the first on a newly redesigned, and much more useful, Socket.IO website. In brief, modularisation, tighter code, binary support (so you can emit blobs and buffers), automated testing, better scalability using redis, more integration (including PHP support), better debugging support (and silence by default), sleeker APIs and CDN delivery.https://codepope.dev/post/2014/05/perl-5-20-released-openduty-open-sourced-and-numeral-js-counted-snippets/Tue, 27 May 2014 11:12:26 +0000https://codepope.dev/post/2014/05/perl-5-20-released-openduty-open-sourced-and-numeral-js-counted-snippets/Perl 5.20: After 12 months of development work, Perl 5.20 has arrived with around 470,000 lines of changes from 124 authors.

Makezine has all the details on the Arduino Zero, announced at Makercon. It’s a 48Mhz ARM cored Atmel chip with 256KB flash memory, 32K SRAM and no EEPROM. There’s 12-bit ADCs, PWM on all digital pins, support for an embedded debugger, a second USB port (who knows!) and it’s all 3.3V. Looks super interesting, but the real questions will come when we find out how pricing works out and how hard it’ll be to use recreate the Zero from raw components.https://codepope.dev/post/2014/05/xbmc-13-openelec-4-0-javascriptcore-and-android-stats/Tue, 06 May 2014 09:45:01 +0000https://codepope.dev/post/2014/05/xbmc-13-openelec-4-0-javascriptcore-and-android-stats/XBMC and OpenElec updated: The XBMC Media Centre app has been updated to version 13.0 with hardware decoding support for Android, performance improvements on Raspberry Pi and Android, support for stereoscopic 3D rendering and better touchscreen, UPnP and Audio Engine handling including “real pulseaudio support”.

It’s tempting to use the various Heartbleed test sites out there, it is much safer and trustable to test for it yourself.https://codepope.dev/post/2014/04/typescript-1-0-ipython-2-0-0-and-rust-0-10-snippets/Fri, 04 Apr 2014 10:01:26 +0000https://codepope.dev/post/2014/04/typescript-1-0-ipython-2-0-0-and-rust-0-10-snippets/TypeScript hits 1.0: Microsoft’s take on reworking JavaScript, TypeScript, has hit version 1.0 and is now accepting pull requests on the open source compiler (though it’s bug fixes only for now.). Meanwhile, Microsoft have embarked on an open source fest with the creation of the dotNet Foundation, now home to a .NET compiler, micro frameworks, Couchbase for .Net, various SDKs, ASP.NET modules and other stuff.

There’s a new realtime scheduler (deadline), event triggers for tracing, graphics driver updates (stablised Broadwell support, NVIDIA GK110 support, dynamic power management for newer AMD hardware), new TCP autocorking for better small packet handling and the usual gamut of driver improvements, patches and enhancements.

Over here at Codescaling, we’re looking forward to the improvements to HiDPI display support . We had been spoiled by Apple’s fairly smooth switch to HiDPI support but on Linux and Windows its all, surprisingly, a work in progress.

What’s changed? Lambda expressions, functional interfaces, default methods for interfaces, streams, a new Date API, repeatable annotations, the Nashorn JavaScript engine… there’s a good quick intro to some the language features but theres going to be plenty of settling in to do.

Before you dash off to the Python 3.4 download page, reflect for a moment that now Python now has pip as its bundled installer and should always be available or that there’s an OO API to filesystems (pathlib), a new async I/O API, support for enumeration types, fresh pickle and more and then go to the What’s new in Python 3.https://codepope.dev/post/2014/03/docker-0-9-vagrant-1-5-and-xen-4-4-virtually-snippets/Tue, 11 Mar 2014 10:44:57 +0000https://codepope.dev/post/2014/03/docker-0-9-vagrant-1-5-and-xen-4-4-virtually-snippets/Docker 0.9 unloads: Docker bumps its version number to Docker 0.9 and as it approaches version 1.0 makes a big change. Docker’s been pretty tightly tied to Linux Containers (LXC) technology to run applications packaged with it but in 0.9 there’s now execution drivers so the option to plug in any one of a range of isolation systems is now available. “OpenVZ, systemd-nspawn, libvirt-lxc, libvirt-sandbox, qemu/kvm, BSD Jails, Solaris Zones, and even good old chroot” are on Docker’s planned list with more to come from various projects.https://codepope.dev/post/2014/03/python-upped-persona-non-grata-markdown-marked-and-more-snippets/Mon, 10 Mar 2014 10:44:57 +0000https://codepope.dev/post/2014/03/python-upped-persona-non-grata-markdown-marked-and-more-snippets/Python 3.3.5 released: The latest update to Python 3.3 fixes two regressions, in zipimport and executing scripts and alleviates a potential denial of service.

It’s a big release with a lot of changes and a lot of new features – an API for selective snapshot/restore, federated search, aggregation, distributed percolation and software “circuit breakers” to stop some more dangerous actions from overwhelming the system. An interesting post from Found.no on ElasticSearch sums up the pros and cons (like no authentication or authorisation) places ElasticSearch in the domain of “secondary store” to be used alongside a primary database.https://codepope.dev/post/2014/02/freebsds-journal-freenas-updates-arduinos-on-paper-and-extra-bits-snippets/Tue, 11 Feb 2014 14:22:10 +0000https://codepope.dev/post/2014/02/freebsds-journal-freenas-updates-arduinos-on-paper-and-extra-bits-snippets/FreeBSD Journal Edition One: The FreeBSD Journal has published its first digital edition for iPad, Android and Kindle devices.

The company uses the library for encrypting data that its apps store on SD cards. It uses pre-selected OpenSSL algorithms, picked for efficient memory management and speed, and gets the library down to 85KB by not trying to be a general purpose crypto kit. An interesting bit of pragmatism which means Facebook’s apps can happily encrypt on low-end Android devices, Conceal is available under a BSD licence with its source on GitHub.https://codepope.dev/post/2014/02/libreoffice-and-mercurial-update-while-firefox-steps-back-snippets/Tue, 04 Feb 2014 10:20:07 +0000https://codepope.dev/post/2014/02/libreoffice-and-mercurial-update-while-firefox-steps-back-snippets/LibreOffice 4.2: The LibreOffice folks have rolled out their latest release, LibreOffice version 4.2 which includes a decent selection of new features, with the headliners being improved OOXML roundtripping, a GPU/OpenCL utilising Calc engine, enhancements to Windows installation and management and better Windows 7/8 integration, an expert configuration window and a more optimal start screen.
