Monzo is something I’ve been keeping an eye on for a while, and having been at the top of the waiting list all summer, I was straight off the mark when they finally launched on Android on Thursday.

At the moment, they’re providing pre-paid debit cards (chip and PIN + contactless) with a really nice app and an API. I handed over my initial £100 top-up late Thursday, they posted my card on Friday (notifying me through the app, naturally) and it arrived today: so far, so efficient. The fact that these are non-personalised pre-paid debit cards helps, as they don’t need to stamp your name onto the card: they can just take one off their pile, note the numbers and post it.

The card is a loud orange/pink colour, but that’s more than made up for by reliably instant notification on my phone (and watch) of transactions being made. As others have blogged, the phone often buzzes with the notification before the retailer has even handed the card back to you. As someone increasingly frustrated by the way some transactions take 3-4 days to show up on the app for my credit or debit card, this is much more like it and appropriately 21st century.

They also don’t charge extra fees for usage abroad; they simply pass on the MasterCard exchange rate. This is another serious annoyance of both my credit and debit cards, and something I look forward to trying out when I travel to ApacheCon next month.

The API also promises the possibility of being able to securely and in near-real time pull details of payments into my budgeting app instead of having to wade through a pile of receipts and enter it all by hand at the end of each week. I haven’t tried that yet, but will report back.

They’re aiming to get a banking licence and run a full current account in this style – a delicious prospect, though I hope they’re thinking about the details as I can imagine instant notifications of every standing order and direct debit on the first of the month being information overload.

Hive door sensor

Since launching Hive for heating remote control, British Gas have rolled out quite a lot of other products which work in the same app and use the same router-connected hub to talk to their end. They all feel quite pricey for what they are, but I decided to try the door/window sensor. Here it is attached to my front door with the supplied sticky pads:

Hive door/window sensorAt the moment, it’s limited to doing push notifications to your phone when the door opens and/or closes; you can specify time ranges within which you do/don’t want the alerts. It’s interesting to see a log of when I leave for work and get home, and given that I’m not the only one with keys to North HQ (I have cleaners), it’s useful to see any other comings and goings.

The alerts are usually (but not always) instant, and show up nicely on my Android Wear watch too.

First week with the Huawei Watch

My Huawei WatchI have myself a Huawei Watch (W1). This is one of those areas of tech that I’ve been quietly sitting out, but having read a few reviews and seen a few friends finding them useful, I decided to have a go.

General impressions

It’s quite handy to have around. My phone (OnePlus Two), like most modern smartphones, is quite a large object, and not one which I carry around the flat with me at home. I also prefer to leave it on my desk at work when in meetings elsewhere on the same floor. All of which means that reminders for my next calendar event, texts, notification and incoming calls often go unnoticed.

The watch fixes all that (as long as I’m within bluetooth range of the phone), and is a nice discrete means of picking up on the important stuff. You can see the caller ID and answer calls using the watch, but you still need your phone to talk into and hear the caller out of. It’d work really nicely with a headset, though, and means you don’t need to dig the phone out of your pocket to hang up on an unimportant call.

The watch also does voice-activated stuff, triggered by the “OK Google” magic phrase. Simple things like creating reminders or sending a text can be done all on the watch – it’s really nice to be able to shout “OK Google, text Bob Smith saying I’ll be there in five minutes” when stuck in traffic, without taking your hands off the wheel or doing anything illegal (driving without due care still applies, of course).

More complicated actions (like a Google search) open the relevant app on the phone, but it can still be a timesaver.

I’ve bought the Pujie Black watch face for it, which allows lots of customization and means I can see a nice visualisation of the day’s calendar and instantly check how many events/meetings I have left today. It also shows both the phone and watch battery status.

It has all sorts of fitness and step tracking stuff which I’ve yet to really get to grips with.

Battery life

Conveniently, the Saturday after I got it, I went to London and went out all night, finishing up with breakfast at midnight [not something I’d do every weekend, but it was kinda fun to do it once]. The watch still had 60% of its battery when I plugged it in to charge at 2AM after unplugging it at 8AM the previous day. And it’s not as if it had had a light day: I’d been showing it off to people and playing with it for much of the time. So that’s quite impressive and suggests it could go two light days without charging.


It’s too soon to tell if the battery will wear out rapidly, but hopefully by the time it does, mobile phone repair shops will be able to swap it out using a soldering iron and a steady hand, much as they can for most phones with an “unreplaceable” battery.

Navigation isn’t quite there yet: the screen is too small and the Google Maps app too immature to be useful, so I reverted to my phone. No doubt it will improve.

As with one’s phone, it takes a couple of very carefully enunciated “OK Google”s before it picks you up. Unless you’re describing the voice capabilities to a friend in a noisy pub, in which case it works perfectly and starts sending the text message you were using as an example.

As with the phone, all the speech processing is done in the cloud, so it stops working if your phone lacks a data connection.

The charging dock is proprietary (and at £29 for a spare, I’ll have to remember to take it with me when I travel) – shame it couldn’t be micro USB or USB C, but I can see it being aesthetically difficult to fit a port of any size into the watch. It has three discrete contacts on the back which line up with pins on the dock when it magnetically snaps in. The dock itself is USB powered, which fits nicely with the fact that I’ve replaced lots of double socket face plates in my flat with USB charging ones.

It requires bluetooth on the phone to be always on, which inevitably affects battery life.

Overall, I’d say Android Wear is worth a punt, and this variant has the advantage of being a classy looking watch in its own right too.

Sip2Sim and the OnePlus Two

Andrews and Arnold do an interesting service where they supply a SIM card which connects to VOIP at their end. Annoyingly, they don’t have a sensibly usable set of 07… UK mobile numbers they can route onto VOIP to go with the service, but since my OnePlus Two has two SIM slots, that seemed like a way to give it a punt…

Double SIM carding it ... like a pro

Double SIM carding it … like a pro (this is the drawer from the OnePlus Two)

The particular variant of SIM I ordered (O2/EU Voice) doesn’t push out to Nano SIM, instead requiring a pair of scissors and a steady hand (or a proper tool, but who has one of those?) As you can see from the picture, I got away with the scissors and it even worked afterwards:

Custom network name and two signal strength indicators

Android has some pretty impressive native support for more than one SIM, and shows two signal strength selectors as you’d expect. As you can see at the top left, the SIM networks (operator names) are shown with a pipe separating them. For some reason you can’t fiddle with this on the control pages, but you can set it when ordering and contact support to alter it.

I ordered a London number on AAISP’s VOIP service to go with the SIM, and that all works as expected. Texts are a bit clunky (presenting as from “SIP2SIM”), but it looks like that may be configurable/changable.

Mobile data appears to go via NAT and emerge from an IP address registered to Manx Telecom.

The two things I really wanted to play with are setting up my own Asterisk again, and using the roaming to get decent data on the train up north. I’ll report back when I’ve had a play.

Station parking

I’ve parked in the long stay at Didcot station a few times recently. It works well enough, but in common with the Oxford park and ride car parks, and many others, the payment mechanism feels clunky.

First time in, you fire up your phone, bash in a long series of numbers to give it your registration and card details, and pay. Second time, I think they’re slightly too paranoid – they remember the location and car (good) but want the last three digits off the stored card (sigh).

What really grinds my gears, however, is that all these car parks have enforcement based on ANPR. So why can’t I go to a website, bash in my car’s registration number, my card details and my mobile phone number, and tick a box saying “charge me and text me whenever I park at one of your sites”. No faffing around on the day, just turn up and park.

It couldn’t be because that would eliminate a revenue stream from mistakes and over-payment based on guesses about return times … now could it?

Classing up the kitchen, part 2

Following on from my first post on this, behold my classed up kitchen with LED worktop lighting:


Looks great, instant-on, uses less power than the old fluorescents and leaves lots of space under the cupboards for the radio, hooks to hang things on, etc. I had to use superglue on the LED strips to make them stay put as the adhesive on them wasn’t up to it – but no real surprise there.

Bytemark charging for IPv4 addresses

We‘ve had a server at Bytemark for many years (since the summer of 2009). For the most part they’ve been good, Towards the end of last year, they started charging for extra IPv4 addresses. This came as no great surprise, given the near-exhaustion of this finite resource, but our modest /27 suddenly represented a 1/3 increase in the cost of our server.

Fortunately, Bytemark agreed to waive the increase until our next annual renewal, after I got a bit shirty about mid-term price increases. Which left us with the joy of consolidating our usage. They’re quite right to point out that the advent of SNI support in all modern browsers, and things like sslh mean we don’t need so many addresses any more, but having parcelled them out to my six users in blocks of 4 (making firewalling easier as everyone had a /30), I had a long and tedious consolidation exercise to carry out.

Happily, many reboots and much faffing later, we’re nearly there and should be able to hand back 16 addresses of our 32 next month, thus cutting our cost by £192+VAT/year.

This has prompted me to take a closer look at going all-IPv6. I’ve ordered a small IPv6 only VM from Mythic Beasts to play with. Teething troubles aside, it works quite well, with inbound proxying for the websites and NAT64 for outbound access to IPv4 services. Running just the one IP stack feels much cleaner and easier to administer, and opens up the possibility of using an IP address per website/service with no danger of running out.

Edit: Bytemark’s original announcement failed to mention that it’s £1 plus VAT for each IPv4 address. Sigh.

Classing up the kitchen, part 1

Since my kitchen radio is older than I am and has various bits missing, I got myself one of these to mount under the cupboards to replace it. This should also help reduce the amount of stuff on the surfaces and make it easier to clean. Of course, this is the obvious time to replace the flickery under cupboard fluorescents and their bulky fittings with a few metres of LED strip. Testing:

IMG_20160707_230817The hard part is going to be cleaning a decade’s worth of grime off the underside of the cupboards to make the surface clean enough for the LED strip to stick to, but the result should look properly classy. Update to come when I’m done…

The imminent demise of Sixxs?

As a long-term user of SixXS, I got an e-mail earlier this year about how I should stop using a tunnel for IPv6 connectivity and ask my ISP for IPv6. And they’ve got a point. After all, now that major bandwidth hogs such as Netflix and Facebook have IPv6 enabled, those tunnels must be shifting some serious traffic.

Having said that, Netflix have recently started proclaiming Sixxs is a “proxy service” which they can’t allow because it lets you pretend to be in the UK wherever in the world you are. Which is fair enough if tedious, and has forced me to move my TV-connected devices onto my guest WiFi network, where there is no IPv6.

I would call my ISP, but EE has been swallowed by BT, who seem to have finally got their act together on IPv6 – if the date comes true. But I’ll probably have migrated off to A&A by then.
