Failing (by sarah)

I've failed at morning - there is pink tooth paste on our bed and Mary only half dressed in the car for school 🙁 Still I think that is the first proper melt down we have had so far this term with getting ready in the mornings so... getting there - of course Jean has taken the bright turquoise coat to school so I am sure we will be getting a letter or she'll be getting a detention or something about that as she's only allowed black ones :/ To be fair her black one is at the school drying out from yesterday still but she was supposed to take my coat!

My chest is still bad and I've failed to finish decorating the girls rooms. I've now been ill since the 2nd of November and am BORED. Hoping it will sort itself asap.

Yesterday was a System of A Down and Cradle of Filth et al kind of day, Jean came home sans coat and bag as they were too wet and she'd been lent other things in their sted. Which was a relief as I thought she'd gone out in the torrential rain without anything!

Today I wonder if she's remembered her jujitsu bag as she's going straight from school with her friend and I forgot to remind her - I can see the bag from here but that does not mean she hasn't got the trousers and t-shirt with her - the jacket is just too bulky for her to carry in with all her school things.

Maybe I'm letting her down by not sorting it all out, by not driving etc - I hope she is just becoming independent. She's actually pretty epic at organising herself considering she is organising herself and she is mine and Al's daughter and she is only 11.

Rain like this always makes me worry - in 2007 before Gloucester but in Gloucestershire we were flooded and ended up being out of our home for about a year. Rains since have caused issues with the new houses roof etc... and though I know that means it's now a good roof... the fear is there tangled in my brain, if it rains heavy I feel I should go and just check that things aren't flooding - because you know I'd be able to do something about it if it where :/

I'm all mouth ulcery - and run down... thinking it's the aneamia, thinking it's still on running issues of having gotten low levels of gluten etc... over the summer etc... but I don't know.

There are happy things to write about just feeling a little deflated so thought I'd share what was going on. Alaric's new job is great - he's loving it but due to traffic in Cheltenham he is not getting home until gone 7 at night and because he does school run in the mornings he's gone for like 12 hours to do do his 9 hr job. This is the first time I've been on my own on my own in the house everyday since having kids... there has always been a kid about and/or a husband. It's weird because instead of the relief of them having their 2 days in nursery it's like... the house is EMPTY.

I think I'm getting less done but I also think I'm getting more done as I am doing the new rest regime from the doctor to try and get the head bang healing properly.

Tomorrow there is coffee with a friend and at some point I need to go and pick up some bits from another... I have stalls to organise for Salaric Craft and The WigglyPet Press for December and I need to decide weather to shut down my Patreon account due to the fact I think I'm going to end up triple taxed on income that otherwise would be taxed once max.

It's a shame I like the platform... :/

Anyway I will now go and up load pics so I can get back to cutsie blogging and political rants.

Steel Pan Drum Making (by sarah)

Dear Alaric and Jean you asked for ideas for welding projects for presents for me - you know already that I would like a tank drum but I would also like what I call a Calypso Drum - these used to be used at the carnivals when I was a kid and also during the candle light parades and things. I prefer the ones without drilled holes but if they are easier to make then that is fine 🙂

This one looks like a lot of work - from having spent time round industrial workshops as a kid I kind of had it in my head you just bashed empty oil cans - the sort my bro/uncle David makes into BBQ's. And I'm sure there was a drum made from the bonnet of a car or maybe they just let me play with non-sharpe metal and stuff to keep me entertained as a kid!

Also there is this little beaut which is painted and stuff - I didn't know they came painted - it is lovely but about £80 and isn't as many notes I don't think.

p.s. you might need to enlist the help of musicians in Cheltenham Hackspace for tuning though Jean you are always moaning at my wrong notes so you should be able to do it yourself! Remember Alaric you do have oscillerscopes!

Brexit (by alaric)

I think the best analysis of the possible consequences, whichever way the referendum went, was this: Martin Lewis' guide to voting in the EU referendum.

In other words, nobody really had any good arguments as to which was better - in or out. The EU has costs and benefits. The problem is, the referendum wasn't about whether Britain would be better in or out; it was about whether Britain should remain or leave, which is a slightly different point. The differences is: the cost of change also enters the equation. Given that the consequences of being in or out are unclear, the question becomes: Is it worth the costs of leaving?

Personally, I don't think so: Even though the consequences either way were unclear, I suspect that the average outcomes are probably slightly better if we'd stayed in. All the talk of immigration (we still need immigration to afford to look after our ageing population), sovereignty (the British parliament is hardly more accountable to us than the European one), and £350m a week were largely red herrings, spectres summoned to try and mislead the population; the real issues were far subtler and more pedestrian.

But that difference between the best predictions of the impacts of staying or leaving on our quality of live are small compared to the cost of change. Today's drop in the value of the pound and British shares is not a measure of the predicted economic weakness of a non-EU UK; it's a measure of the uncertainty as to how effective British business will be, and how easy it will be for multinational corporations to operate in Britain. The world cannot predict how fiscal and commercial relationships with Britain will be in five years, let alone ten or more, and those are the kinds of periods over which major investments are planned; so that investment will be directed to safer places. Maybe Britain will become a new economic powerhouse without EU regulations - or maybe it will become a dingy backwater. The world doesn't know, so it's moving its money elsewhere. Funnily enough, that reduces the chances of Britain being able to become an economic powerhouse, because we're poorer to begin with.

Another effect that's far larger than any predictions of the effects of being in or out is the effect of the referendum process. We are now in a situation where half the country is furious with the other half for having ruined their country, and possibly the world. Meanwhile, that half is furious with the first half for having nearly prevented them from saving their country, and possibly the world. This is a rather toxic and explosive situation to now be attempting to plan what's going to happen over the next five years. Many decisions will be made based on personal grudges rather than rational consideration. Meanwhile, in the populace at large, a lot of resentment is simmering; if living conditions drop in ways that are attributable to our leaving Europe, the half of the population that voted for it will be considered personally responsible for ruined lives. That could get nasty.

Another effect of the Leave result that probably dwarfs the actual cost of not being in the EU is that the result has emboldened the more right-wing figures in British politics. Folks who have traditionally acted in the interests of big business and the rich, while cynically appealing to the fears of the masses in order to get their way. I'm concerned that their influence - previously more rhetorical than actual - will grow in the political changes coming, which could have negative long-term consequences.

So, I'm sad on many levels about how this referendum turned out; but I wouldn't have been very much happier if we'd voted to remain.

Towards the Family Mainframe (by alaric)

Last September, I posted progress on the construction of our domestic mainframe. To recap, the intent is to build a dedicated home server that's as awesome as possible - meaning it's reliable, safe, and easy to maintain. That rules out "desktop tower PC in a cupboard" (accumulates dust bunnies, gets too hot, easily stolen, prone to children poking it); "put a 19" rack somewhere in your house" is better, but consumes a lot of floor footprint and doesn't fix the dust bunny problem. So I've made my own custom steel chassis; fed cold air at pressure via a filter, incorporating a dedicated battery backup system, locked and anchored to the wall, and with lots of room inside for expansion and maintenance.

Since that blog post, I've finished the metalwork, painted it with automotive paint using a spray gun (which was a massive job in itself!), fixed it to the wall, and fitted nearly all of the electronics into it.

A significant delay was caused by the motherboard not working. I sent it back to the shop, and they said it was fine; so I sent the CPU back, and they said THAT was fine; so I sent both back together and it turned out that the two of them weren't compatible in some way that was solved by the motherboard manufacturer re-flashing my BIOS. That's now up and running; I was able to use the HDMI and USB ports on the outside of the chassis to connect up and install NetBSD from a USB stick, then connected it to the network and installed Xen so I can run all my services in virtual machines. It's now running fine and everything else can be done via SSH, but the HDMI and USB ports are there so I can do console administration in future without having to open the case (unless I need to press the reset button, which is inside).

The one thing it's lacking is the management microprocessor. I've prototype this thing on a breadboard and written the software, but need to finish off the PCB and cabling: but it will have an AVR controlling three 10mm RGB LEDs on the front panel, and three temperature/humidity sensors in the inlet and outlet air (and one spare for more advanced air management in future). But the idea is that the three LEDs on the front panel will display useful system status, and the environment sensor data will be logged.

Here's what it looks like from the outside; note the air inlet hose at the top left:

The socket panel on the left hand side worked out pretty well - 240v inlet at the bottom, then on the aluminium panel, three Ethernets, HDMI, and USB (my console cable is still plugged into the HDMI and USB in the photo, which won't usually be the case):

And here's the inside, with lots of space for more disks or other extra hardware; the big black box at the bottom is the battery backup system:

Now I have Xen installed, I'm working on a means of building VMs from scripts, so any VM's disk image can be rebuilt on demand. This will make it easy for me to upgrade; any data that needs keeping will be mounted from a separate disk partition, so the boot disk images of the VMs themselves are "disposable" and entirely created by the script (the one slightly tricky thing being the password file in /etc/). This will make upgrades safe and easy - I can tinker with a build script for a new version of a VM, testing it out and destroying the VMs when I'm done, and then when it's good, remount the live data partition onto it and then point the relevant IP address at it. If the upgrade goes bad, I can roll it back by resurrecting the old VM, which I'll only delete when I'm happy with its replacement. This is the kind of thing NixOS does; but that's for Linux rather than NetBSD, so I'm rolling my own that's a little more basic (in that it builds entire VM filesystems from a script, rather than individual packages, with all the complexities of coupling them together nicely).

I'm using NetBSD's excellent logical volume manager to make it easy to manage those partitions across the four disks. There are two volume groups, each containing two physical disks, so I can arrange for important data to be mirrored across different physical disks (not in the RAID sense, which the LVM can do for me, but in the sense of having a live nightly snapshot of things on separate disks, ready to be hot-swapped in if required). I still have SATA ports and physical bays free for more disks, and the LVM will allow me to add them to the volume groups as required, so I can expand the disk space without major downtime.

So for now it's just a matter of making VMs and migrating existing services onto them, then I can take down the noisy, struggling, cranky old servers in the lounge! This project has been a lot of work - but when I ssh into it from inside the house (over the cabling I put in between the house and the workshop) and see all that disk space free in the LVM and all the RAM waiting to be assigned to domU VMs that I can migrate my current services to, it's all worth it!

Shakespearian Mock Tales (by sarah)

Last night we had the second ever Mock Tales - 2 hours of stories and writing creativeness with sticky non-alcoholic cocktails. They were Shakespeare themed as it was his 400th birthday at the weekend 🙂

I did 20+ pages of my comic book script/story board and now know how this story arc ends, Alaric managed 5000 words of our joint novel/series.

There were 3 of us so I was limited as to how many drinks I could make!

Above are Twelfth Night which was minty, Midsummer Nights Dream which was vanillary, The Scottish Drink which was fruity, and The Tempest which was Sugary.

We also had home made Pizza which was dairy and gluten free - Mary had opinions...

I remembered that when I was in secondary school I became obsessed with The Tempest as a story and drew the whole thing as a comic - I wonder if it survives somewhere? I loved the stop motion animations they did of the shakespeare stories I need to try and find them for the girls.

Jean tried a Tempest before she went off to best - she was a little horrified at it's stickiness - she still drank/ate it.

Recipes are being written down for Salaric Cooking before people start prodding again 🙂
