2021-11-08 Making a House a Home

Another five months, huh? Fine, I guess this is something approaching a schedule, at least. I've been tinkering around the edges of the house hanging some pictures and organising my bookshelves, and I've just dug out the corpses of the sunflowers that I grew up the side of the house this year to replace them with daffodil bulbs. But that's not what I want to talk about today.

I've been living in my house (MY house. It's still weird) for about eight months now, and I'm mostly set up and unpacked and starting to think about what changes I want to make to the place. The single-glazing is an obvious target, as is the gas boiler (from a climate-change perspective), but tweaking a thing here and a thing there is never the most effective way to do things. I found myself an architect who specialises in refit and eco-retrofit projects, and set him loose on the house to work out everything that needs doing, and to try and build sensible combination-packages from those things so we could derive a plan to fully upgrade the house to be the best it can be.

By "best" here I think I mean "most efficient", both in terms of greenhouse gas emissions and in terms of running costs. The work involved is expensive and time-consuming, so from a pure financial perspective it won't fully pay off for several decades, but I'm not only looking at money. As someone who can afford to do major retrofit work on their house, I want to do the best I can and to absolutely minimise my impact on the environment - in part because I can and in part because not everyone can, and every little helps (a little).

Let's talk numbers for a moment. This is an end-of-terrace house, built in the 1980s, with single-glazed windows and gas central heating using a wet radiator circuit. There's some loft insulation, but it's patchy and barely 100mm thick at best. Several of the doors and windows are draughty, and the extraction fan from the bathroom is a hole in the wall with a powered turbine in it. One of its few saving graces from this point of view is that the walls were built as filled-cavity walls, with slabs of some kind of foam between the brick skins. The architect came and took a lot of measurements, and plugged them into an industry-standard planning package, and came back with a figure of 2.2 metric tonnes of CO2 or CO2-equivalent greenhouse gases being emitted simply to heat this one house, every year. That's ... I don't even know how to comprehend that number, and that's one house. That's a lot, for one house. And it's a fairly standard house, which implies that a lot of houses in this country have those kind of emissions figures. Still. The architect I'm working with has laid out a fairly reasonable package of retrofit work that will pull that down to 200kg, which is still a lot, but at that point the house is run entirely by electricity so hopefully future decarbonisation in the power generation structure of this country will pull that down some more. A notable side-effect is that the heating bills for the house will fall from approx £450 to £200. So it's entirely worth doing, for all that it's looking like about £40'000 of work over the next decade or two.

The plan is as follows, in four sequential stages of work:

  1. Reinsulate the loft to 400mm insulation depth, adding an airtight layer between the ceiling of the first floor and the floor of the loft. The airtight layer is basically about draught reduction - any air you heat and then vent out of the house is energy wasted, so you want to exchange as little air as possible with the outside world. When all four stages of the work are done, the house will be pretty much airtight, which is why this stage also includes a mechanical ventilation system with a heat-exchanger in which outbound warm air heats inbound cool air - so I don't accidentally build a suffocation trap instead of a house. The mechanical ventilation system will have a duct leading into each room in the house, and will move a very small but continuous current of air through it. It turns out that running an efficient electric motor to do this is significantly less expensive in terms of power used than heating the escaping air, so much so that running the motor pretty much disappears as a rounding error in the final calculation. This stage also includes boarding the loft as a storage space and including a loft-ladder with an air-tight ceiling hatch. A sealing ceiling hatch, if you will.

  2. Fit 4" of non-flammable wood-fibre external wall insulation to all three exposed walls of the house, and inject a self-curing insulative foam into the party wall linking my house to the one next door. The exterior finish on this insulation is currently undecided and there are several options: a lot of people with EWI just render over it with cement or pebbledash and paint it white or cream, but it's possible to have fake bricks installed (5mm slices of brick, laid as a skin over the insulation) and I would personally prefer that if we can make it look good, so the house doesn't stand out as weird among its self-similar siblings in the estate, which are all brick-built. We unfortunately can't insulate the floor because the house is built on a concrete slab, so as an alternative the EWI will extend over a foot below ground level to wrap around the edges of the slab. This stage also includes an air-tight layer on the walls, new triple-glazed windows and new external front and back doors.

  3. Replace the existing gas heating/hot-water boiler with an Air-Source Heat Pump, for heating and hot water. ASHPs have a reputation for being expensive to run, and they are ... if the preceding insulation steps haven't been done. An ASHP installed into an existing property as a direct replacement for a gas boiler will broadly-speaking fail: it doesn't have the power output to heat the house effectively because so much heat is being lost to the environment, it's trying to bail out a boat with a hole in the bottom. Plug the hole (insulate the house) and the ASHP will be able to do the work without working so hard, and as I understand it the electricity costs of running it in that scenario are typically slightly less than the equivalent gas for a gas boiler.

  4. Now that the house is run entirely on electricity, remove and cap the gas line feeding the house. More relevantly, install eight solar photovoltaic panels on the roof, and a battery system to smooth supply and demand. That's right,the final step is basically micro-generation (although eight solar panels can't power my house completely, we're still going to be drawing from the national grid and that's where a lot of the remaining CO2 emissions come from). As a radio-amateur, I'm a little concerned about the RF noise that such a system can put out, but well, shielding and filtering and isolating the inverters in the PV system sounds like a solvable problem.

The above plan doesn't include all the minor work: I'm planning on rewiring the house in stages and replacing the distribution panel, as well as putting a new (roller-shutter) door on the garage. I'll repaint some rooms, no doubt, probably run some network cables in the walls, fiddle with the garden, maybe change part of the kitchen/bathroom at some point ... homeowner things. But, I'm going to try and push the big four in that plan through over the next decade as funds are available. Just as well I don't have expensive hobbies or take lots of distant holidays, I guess. I'll post about things as they happen, and I'm happy to talk about the project some more if people want me to.

2021-06-28 Gardening

I seem to be establishing a pattern of posting once every five months or so. Better than before, but I'd prefer once a month at least. Will have to work on that.

So, yes, you'll possibly have noticed that GHE doesn't have HTTPS yet, and that it hasn't sprouted any other new features. Finding the time to work on it amongst the other things I'm trying (somewhat ineffectually, possibly due to thrashing) to do has been difficult.

I got my amateur radio license (and am now callsign M7DFS), and I've been doing a lot of unpacking and, surprisingly at least to me, quite a lot of gardening. I've enjoyed puttering about with the occasional small container garden in rented places that would allow it (my last flat had a strict cars-only policy in the car-park), but that's been kind of it. Since moving here and inheriting a slightly overgrown but fundamentally established trio of gardens, I've got into it a bit more and I've got to admit I'm finding it kind of pleasant. The back garden is still slightly overgrown, because I've been prioritising the others at present, but the side garden (a metre-wide strip of soil between house and driveway) now has some temporary sunflowers and three well-established and de-weeded lavender bushes in it, and the front garden has had the huge weeds pulled out and the buddleia trimmed back, and I'm working on making the lawn less of a weed-filled mossy horror. I find myself looking forward to doing more work on it, which surprises me a bit but there we go. I do have some containers of veggies growing in the back garden at the moment, and I recently found some strawberries buried in the weeds in one of the beds of the back garden, so there might even be a bit of a harvest as the result of my efforts. Here's hoping, I guess. It would be nice to get something more than basic getting-by out of this year.

I have a fair few things in a "nearly done, just needs a bit of work" state at the moment, and hopefully I'll be able to push a few of them through to completion soon. One is infrastructure work on this website, and I imagine I'll talk some more about the others as they arise. Hope you're doing alright, reader, where- and when-ever you are.

2021-02-03 New Beginnings

To all things, their season. As of December 8th 2020, I'm no longer tenant to any landlord save the bank. That house I was talking about in the last post? Reader, I bought it.

So, now I own a little end-of-terrace three-bedroom house a little north of Cambridge, on a quiet suburban side-street. I have a tatty front lawn and an overgrown back garden, and a garage that's full of boxes to unpack, but I never have to put up with another scheduled inspection again and I never have to open the front door to anyone I don't want to. It's liberating. It's nice.

It's not yet cosy, but I'm working on that. I have a functioning office, bedroom, kitchen and bathroom and a mostly functioning living room: it like the garage is full of boxes and assorted tat right now. I also have a spare/hobby room, which contains my model rail stuff and a desk with a soldering iron, but not the folding bed/seat one might expect in a spare/guest room. One thing at a time - furniture shopping during a pandemic in times of Brexit is hard.

Hopefully, this year I'll get the rear windows on the house double-glazed (currently we're single glazed in partially rotten wooden frames, so that needs done fairly quickly) and grow "some" veggies in the back garden. Some minor roofing repairs are also needed, but for the most part this year's primary goal is to rebuild some savings after buying a house. After that? I've a laundry list of improvements I'd like to make and some are more urgent or important than others. Let's see what feels necessary when I'm in a position to do more work on the place.

Other than housing? Living a vaguely normal life during a pandemic is hard. Working from home during a pandemic is hard. I'm learning to cook new things, and playing through my back catalogue of computer games, and thinking hard about what the next steps are on my model railway, the D&D campaign I'm running, and indeed this website. I'm probably going to implement HTTPS on GHE fairly soon, meaning that it'll gain a padlock in the address bar, and I'll be doing some back-end stuff to set up future development. Maybe visitors will notice, maybe not, who can say?

It passes the time. Which is much of what we're all trying to do right now, I think.

2020-09-14 - Moving again

Well, turns out I was right to be worried about the valuations agents that have been round recently. It's been a few weeks, but I've been busy, starting with instructing my letting agents in the basics of tenancy law. Initially, they sent me a standard two-month Section-21 (no-fault repossession) form - unfortunately for them, the Coronavirus Act of 2020 requires a minimum of three months' notice for notices sent after the end of March. I pointed this out, and they replied with a three-month Section-21 notice ... shortly after the Government had extended the notice required in the Coronavirus Act (as amended) to six months. It doesn't appear to have been their month. Still, when I pointed it out they gave me a final six-month notice. Fair enough. I aim to be out well before then, but I'll be damned if I'm going to accept an illegal notice after the trouble they've given me here.

So, as a result I need a new place to live. Times, as they say, are tough. So be it. I jumped into the local housing purchase market, on the basis that I was planning to buy at some point and with six months of lee-way I might as well give it a shot - can always fall back into another rental property if it doesn't start working out in a couple of months, right? Long story short, it's a couple of weeks later and my conveyancing solicitors are working hard on the contract for a house, with expected completion some time in late October or November. So that's a thing... I must admit, even with the Cambridge market's reputation for fast moving I wasn't expecting it all to go by that quickly. The house I'm in the process of buying was on the market for a grand total of one working day, and in that time it received three offers.'s going to be so lovely not to be beholden to a landlord, at last. Sure, if something breaks I have to fix it or get it fixed myself, rather than complaining at the letting agent but also I can have a proper garden, I can tweak the house to be exactly how I want it, and I don't have to worry about people demanding access to tell me the place is a mess. I'm looking forward to it. And I already know the first bit of work I'm going to do on the house (double glazing, as it doesn't have any yet).

There'll be a guest-room / library, and a proper permanently-installed model railway, and one day there'll be a gaming table and I can have friends round to play D&D without having to worry about whether we'll all fit in the living room. When the Covid-19 situation is less serious, of course - for now, the only way people are visiting my house is by webcam.

Wish me luck.

2020-08-24 Oomed. We're Oomed, Cap'n

Three quarters of a year since my last post, whoops. So, there's been some problems here - mostly technical. Let's see...

First, the VPS (virtual private server) that hosts glasshalfempty was being heavily crawled by search engines (hey there Bing, how you doin'?), and having some trouble handling the load. It turned out that there were two problems: the database back-end (psyco-pg2) was erroring out, and the server was running out of available connections.

So, I turned off connection keepalive in apache, which isn't really ideal but prevents this small, cheap VPS's RAM from filling up with paused connections when a web spider is stomping all over it. Side note, I should write a robots.txt. Anyway... The database is currently entirely turned off, because this stop-gap version of GHE is rendering posts from markdown files in a directory - no database interaction at all right now. Side note the second, I should fix that too. Still, GHE is now less prone to crashing when Bing decides to come hammer it. Apache still falls over, but it comes back after a few seconds and it no longer locks up the server altogether.

Next problem,, the firewall/router I was using here, is down. It simply stopped transmitting packets through itself one day, and when I hooked up a spare screen and keyboard its BIOS professed no knowledge of its own boot disk. I suspect the SSD it was running from died for some reason - it's still under warranty so I'll ask the seller to fix it. Side note the third, I should do that, too. It's been replaced with an older, less capable unit in the mean time.

Next problem, I tore an actual chunk out of my foot overbalancing backwards on to a sharp piece of metal in my kitchen. I did the first-aid and wound care thing like I'm trained to (after a few seconds of panicking and bleeding on the kitchen floor, like a real human being), and it's healing up pretty well. Don't need it right now.

Next problem ... well, the whole pandemic thing. Covid-19 means that I've been working from home since March, and I've been getting kinda strange and bent out of shape from the lack of exercise, scenery and human contact. I play D&D with some friends via video-conference every couple of weeks and I see some people every so often, it's just. Weird. A bit like being in jail (except that I can go out whenever I like and I have all my stuff). Which brings us to what is I hope the last problem for now: landlords.

My landlord here is having the place revalued for mortgage purposes (apparently). This is theoretically fine, but any interaction with my landlord puts me on edge these days. I'm quite sure they're going to kick me out, which is probably unreasonable. Although... I've had two valuation agents round to look at the place, and they were both perfectly pleasant to me, asked a few questions, made some notes and left. Today I discovered that they complained that the place was untidy and they couldn't get into some areas to take a look. They didn't use their words. Ask, and it shall be given / I will move stuff for you. I've been shifting stuff out of my storeroom and bedroom into my car tonight, for about an hour: the car's currently undriveable because of all the stuff jammed into it, but an inexperienced person can now probably get everywhere in my flat without stretching or balancing. And I do mean everywhere, including to the back of the storeroom and behind my bed.

And people wonder why I hate landlords and letting agents so unreasonably so.

I'm actually not comfortable with the amount I dislike them. They're people, they're doing a job for a paycheque and they're probably kind to animals and give up their seats to old people on the bus, for the most part. All my interactions with them have the form "you're not good enough", "pay us some more money" or "I'm going to mess with your life for no clearly defined reason", though, and that has grated for a long time.

So I guess it's a good thing that I'm hoping to move into a place I own in the next six months or so. Nowhere lined up yet, and a lot of ducks to align before I can do it, but I've kicked the project back off now after a couple of years of licking my wounds from it all falling down last time. I've a couple of mortgage brokers to try, and I'll be setting up some saved searches real soon now.

Let's see what happens. It's basically the only option we have right now.

(no, I do not want to talk about Brexit)

2019-11-06 So it begins...

It was the day after Fireworks Night, and all through the house, not a creature was stirring, not even !BANG! Oh. Oh dear.

Well, never mind that. It's past Halloween and past Fireworks Night, so I guess Christmas is the next item on the calendar. Time for mince pies and mulled wine and all that good stuff - myself, I stay away from it at least until December starts but it's in the stores from October, so if it's your thing knock yourself out I guess.

Unfortunately, it's also the time of year for "'Certain areas of the country' hate our poppies" and "You can't say Merry Christmas any more" and other shitty nonsense to do the rounds on social media. It's got to the point now that the Royal British Legion (they of the poppies) have had to issue a series of statements over the years saying that the former is total rubbish (it's also dog-whistle racist to boot, as those 'certain areas' being talked around are never predominantly white and middle class, but the RBL didn't address that one). The latter is a slipperier customer, given that it's so vague and personal-point-of-view ranty to begin with - I can easily put up an opinion-piece to counter that opinion but it's not particularly well-sourced or authoritative. Frankly, though, if your particular rant is well-travelled enough to be included in a wikipedia page and debunked there too, I feel I don't need to put too much time in.

These social media posts are "interesting" to me because they seem like examples of weaponised memes in the wild. An idea with all of emotional resonance, a reason/desire for the host to spread it and a coat of reasonability surrounding a hijack payload designed to turn a reasonable person into an infection vector. It spreads through the networks of modern social media, from host to host, and even those immune to its payload start to question their own beliefs once it starts appearing everywhere. As an engineer and a citizen of the Internet, I feel like I should understand how this kind of thing works. I really don't, though, and it's increasingly clear to me that some people do. Maybe if I'd put some time into the (at my school) generally derided "easy soft classes" of sociology and media studies I'd be better equipped to understand - I've certainly been schooled often enough by friends who did study those subjects to recognise a gap in my mental armoury. I think it's harder and harder as time goes on to justify putting all of your time into learning the new computer languages and server technologies of the day without putting some time into psychology and human sciences. Ad companies and other groups who want to make people think particular ways (e.g. political parties) have people that specialise in messaging and "spin" and making groups of people think in a particular direction for a few weeks at a time. We, the people of the Internet, need better defences.

That got dark and a little tinfoil-hatty, but well, it's hard not to in this climate of lies in the news, lies on the net and apparent weakness or unwillingness of legal justice. Over the next few weeks I'm going to give some time and money to Full Fact, who are an independent fact-checking charity, and if you have either spare I'd encourage you to do so too. Their site is a good read and a good resource when you spot another piece of poisonous nonsense floating by, and we need organisations like them now more than ever, what with Brexit and the ongoing Tory Omnishambles in the UK and the rise of Trump and the ruin of the Republican party in the US.

Enough about the world. As a wise person somewhere on the internet said, "We became a global species overnight, and it's giving us PTSD". We're set up for things happening in our local area and to our little community, and now that we see glimpses of a thousand other communities a day via Twitter and Facebook and so on, it's hard to keep up with all the changes and problems people are having, even though the rate hasn't changed - we just see more of them. The world is full of darkness but little lights still burn in our hearts, and it's wise to cherish them if you can. Happy Equinox, welcome the dark of the year and look for the rising of the spring. Keep safe, so far as you can, and guard the backs of your friends and neighbours through the long nights.

2019-01-25 New Firewall

I've just finished installing a new firewall machine for my home network, and I thought I'd write about it here in the interest of having something to write about, and because it's useful to talk about how things went so other people can learn from your experience. So here goes.

The firewall's hardware is an NA204 network server appliance from, with a Seagate Barracuda 500GB hard disk. I had the Mini-ITX store build it, which means it comes with a 3-year warranty - can't argue with that. The NA204 is based on the Jetway JNF9HG-2930 motherboard, which has a quad-core Intel N2930 Celeron processor clocked at 1.83GHz, 4GB of RAM and integrated Intel graphics. In addition to all that, this unit has a daughterboard with four gigabit Ethernet ports, which makes it ideal for jobs like this.

Softwarewise, we're running pfsense 2.4.4 (docs), which is based on FreeBSD 11.2. It's a UNIX, which means I can get into its guts if I need to (though I'm not as familiar with it as I am with Linux). That became relevant during the install, as I'll mention later.

The installation process was pretty standard, at first. I burned the pfsense installer to CD from an ISO image (after checking the checksum), slipped the disc into a USB optical drive and plugged it into the front panel of the NA204, along with a monitor and keyboard. The UEFI on the motherboard picked up the optical drive without any problems, and gave me an option to boot from it (press F7 during startup to pop up a boot menu), and the installer ... choked. It gave me the a nice ascii-art welcome screen and started scrawling bootup information on the screen, and then just stopped.

It turns out that on certain graphics cards, the FreeBSD 11.2 installer is known to fail to correctly discover the properties of the screen, and it tries to set the resolution to a size the GPU can't support, and the GPU gives up and dies. Thankfully, it's an easy problem to fix. As The Geek Pub's "pfsense-hangs-at-booting" states, there's a kernel parameter (kern.vty="sc") that will set the resolution and disable discovery, so I passed that to the installer kernel at boot time and then dropped the relevant parameter into the bootloader config (/boot/loader.conf) with vi so that it would always apply in the future.

At that point, the install proceeded to completion and it was on to configuration, firstly of the interfaces. I thought this was pretty neat. To tell the machine that a particular interface is the WAN port, for example, you unplug all network cables from the machine and then select "WAN port", "auto" and plug a network cable that has a device of some kind on the other end. pfsense will then notice the Link Up event from that cable being plugged in, and associate the port it came from with that interface. And so on for the other ports (LAN and WAN are required for obvious reasons, and I assigned the other two interfaces to WIFI and DMZ for future use). Very neat. A DHCP server came up automatically on the LAN port, which had set itself to by default.

Unfortunately, my ISP's modem's wifi router was handing out .1.x addresses. I'd disconnected from the wifi but not disabled the wifi adaptor. This meant that my wifi card had, and was hanging on to it in case it reconnected. There then followed a tiresome dance of my plugging a cable between my laptop and the firewall and trying to go to the firewall's webconfig page to finish setting it up, and my laptop saying "...there's nothing there." Of course, I pinged it to see if the web browser was lying, and I got a response! It took a depressingly long time to work out that the response I was getting was from my own wifi card. Then I reset the firewall's LAN port and DHCP to 192.168.2.x and everything started working.

So there you have it: the story of my pfsense install. I'm liking pfsense, because it's highly configurable and exposes a lot of options. That same option profusion makes it... probably not ideal for inexperienced users - I've been maintaining house-LANs for years and I don't understand some of the options yet. But, if you're looking for a tough, reliable, configurable firewall I'd recommend pfsense. And if you want a machine to run it on, the NA204 is really rather nice.

2018-10-22 Living in a box

OK, new flat, new start - in theory, at least. It's a month and two days since I moved in here ("here" being Milton, a couple of miles north of where I used to be), and everything is still everywhere but things are starting to get sorted out. The kitchen is usable if I'm willing to shift stuff about to make room on the worksurfaces, and I can walk into and out of all the rooms and more or less use them for their assigned purpose. Still need to assemble the media centre and get the packed clothes off the sofa, but it's not too bad for somewhere I live.

This is not forever. It's a small flat with a cheap rent and slightly questionable facilities, on a 12-month contract with the option to extend at expiry. Long enough to get my feet under me, have a damned good sort-out and get rid of some stuff I don't need. Long enough to get my head back together and find somewhere to live longer term.

In other news, hey, glasshalfempty's up again. The new place struggles to manage 1Mbps, so I'm not hosting the site in my living room any more - we're coming to you live from a linode in Frankfurt and I upgraded the site to use Python3 while I was at it. Easier to upgrade now, while there's not much to upgrade.


2018-07-20 Life in boxes, 2018 edition

An out-of-band update here, to note the following: I've just received two months' notice on my flat, meaning that the landlord wants to take possession of it no later than the 20th of September. This kind of thing is why I hate renting - the lack of control, the lack of warning, the difficulty of planning anything when you don't know when someone you've never met is going to pull the rug out from under your feet. It sucks. It happens. Gotta get over it.

So, I've rented a storage unit and ordered in some flatpacked moving boxes, and I'm going to start looking for another rental in the next few days. I was planning on trying to buy a place of my own over the coming winter, but that's out the airlock now: there's no real chance of exchanging, completing and moving in two months and once I'm moved to a new place I should probably stay there for at least six months/a year (since that'll be the initial rental contract). The move, at least, gives me an opportunity to declutter and reorganise in a way that's difficult when everything is in its familiar place - I'm aiming to shed up to 20% of my equipment volume, which should make the second move substantially easier when the time comes.

Let's see what happens. I'm going to a LARP event next weekend and a convention the weekend after, both booked months ago, so I'll survey the market and move stuff to storage until after the con, then start looking in earnest.

2018-02-28 Technical Debt

It's been a very long time.

Some of the wait is because I kept being busy, having better, more urgent or somehow more distracting things to do. Some of it is because the feedback loop through the old site is broken (along with the old site), so I don't remember that it's important or interesting to some people. Some of it is because the hardware upgrade stalled amidst a series of sick hard disks a couple of years ago, and I haven't gotten back to it. Doesn't really matter.

I've been drowning in details for the last few years, I think, and hadn't realised until very recently. I don't like putting things online that aren't the best I have: if people are going to have the opportunity to critique something I've made, I'd like it to be as good as I can make it. Less than perfection, say some parts of my mind, is waste. There are at least three versions of New GHE that will never see the light of day, because I abandoned them because they were wrong or incomplete or poorly designed.

I'm going to try not to care about that any more. This is an experiment, but fundamentally I'm an information designer/software engineer/technical author/whatever. I trained as an embedded software developer, and a computer and AI scientist. I never trained as a web designer. I've never claimed that my websites are the best they can be, and chances are that this one won't be. It'll be as secure as I can make it, because that sort of thing matters, but it won't have lots of features or use up-to-the-minute CSS or be perfectly standards compliant at all times.

Here's the very beginning of Glasshalfempty 3.0, or 3.0.0-alpha1, I think we'd call it at work - the first alpha version of 3.0. It's incomplete and probably buggy, there isn't even a blog here yet, just a framework and some HTML and CSS. I'll bring more things online in time.

But I got some queries from old friends recently that made me wonder why it wasn't online, and I found I had no good answer, only excuses. So here we are. Join me round the campfire, I guess in companiable silence for now. Blogging, commenting, all that fun stuff, is in the future, so silence is the only option you have anyway.
