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!

Slams and Other News (by sarah)

Tonight Friday 13th I will be performing in the Cheltenham Poetry Festivals Slam - Slam Burger. I will be swearing on stage, in a poem, this is actually an incredibly hard thing for me to do... I can just see all the little old ladies from the church of my youth frowning at me in my head - none-the-less the poem needs to be said and so it shall be.

I will still come last 🙂 I always do! (Except the time I came second from last!). But I do tend to get myself mentioned in news papers with poems that are "rants against the government", even if they can't spell my name right (newspapers never get my name right! or if they do they spell my kids or husband's name wrong!). The article is from last weekends Slam - a fantastic even of sparkling dark and joy.

It was the 20th annual slam and I think the longest consecutive poetry slam in the UK. I poddled down there with the lovely poet, actor and comedian Joy-Amy who unlike me came a fantastic and well deserved 2nd 🙂

In other news I am still uber busy with the colouring book visual poem A Stranger Dream: Love that a launched at the end of April. It is steadily selling and I have actually gotten around to sending out some review copies (yes I know it is supposed to happen before you release the book 🙂 ).

I sold out of the heart handled mugs with the art work Love on it - one of the pictures from the book. I have ordered more and they have now arrived 🙂 I am still sorting out the Normal Mugs with normal handles but will have them soon 🙂

Yesterday the first lot of artwork badges arrived and I have homed 3 of them already 🙂

There is a still quiet a bit of a to-do list to get everything I want to go with the book/be done with the art work 🙂

So far no bad reviews (that wont last but for now I am basking).

I am down to just two copies of the books I had to sell - there is another lot en-route, I will have them with me tonight at the poetry slam. Otherwise the next chance to buy the books and artwork stuff from me is going to be The Mini-Mall Con in June 🙂

(I may also be making Alaric dress as young spock once again which as those who came to my 30th know is a treat worth it's weight in jelly beans!).

Of course you can order it on line from Amazon.

I hope to be doing more shows, stalls and things with it and I will be seeing if I can make the video of good enough quality to maybe show at an event but we are looking at next year for that sort of thing 🙂

Stories and poems are starting to go up on the various Monster Blogs once more which has been a long time coming thanks to head bang stuff. However slight change... they now tend to get pre-viewed on my Patreon account for those who are supporting me financially - to be honest though it paid for me to launch and create A Stranger Dream I still do not have quiet enough to be replacing the tech I need to replace and to make the blogs ad free etc... So if you find yourself with monies and you want to see stories and art from me... (yeah I hate asking for money but you know it has to happen or I actually can't afford to be producing this stuff!).

Anyway.... my patreon.

Also - yes a lot of alsos 🙂 I will have art at Art in the Park Cheltenham this summer.

And lastly - I really liked working on A Stranger Dream colouring in book, about 2 weeks in I made a list of other colouring in books I would like to make both poetry and not poetry based. So last week I popped a poll up to narrow down which one to work on next. I only gave four options and the ability for people to suggest other things... the resounding favourite option was Myths and Legends so I have started work on that.

I have a couple of commissions at the moment so it has to fit in around them but it has begun!

.....

Opps I lied one more thing or maybe two!!!

I will be doing a set at Science Show Off in Bristol on Weds 25th of May at the Grain Barge - there will be stars and poems and possibly a puppet but hopefully no singing!

And there will be steam punk and science-craft workshops run by me at Wychwood Musical Festival 🙂

I do have a news letter...

I think that's everything but probably isn't!

Hope to see local peeps tonight!

The Blank Doll (by sarah)

I have wondered about sharing this before but it is a silly memory really... it's about a rag doll, sort of, not a mookie made from scraps of old cloths and not a rag doll like my Jack and Jill/Gamima - no this was another sort.

It was stuffed with sand, made of a coarsish cotton but not hessian, it was off white or at least that's how it started. It was never a fine linen. It ended up frayed, and mottled, I think it maybe in this house if not possibly still at my parents.

I sadly lost the accompanying bag long long ago, it was filled with amulets or totems or my treasures - fossil shell, pink iridescent turtle bead, blue plastic mermaid, a red stone, an acorn cup stains with a circle of elderberry juice from the school field - you get the idea. The doll would nestle in these things and I'd carry the bag around.

My nan gave it to me, my nan made it, I was being bullied... badly, I'd been very ill... very (as in blood transfusion going wrong), and so on... one nan tried to stop the nightmares with lavender; the other gave me the blank doll. It had a circular head and segmented arms and legs, a shapeless, featureless thing.

"It can be anybody you want it to be" she told me. It had no eyes, no mouth, no nose - nothing. It scared me, it was a vulnerable, powerful thing. It was mine, it belonged to no one but itself. It was kind of flat and 2D.

It was me, it was my enemy, it was everyone, or so I decided. If it could be anyone then why not everyone... and so I cared for it and looked after it and put it in the bag of things that were special. In the way of a powerless child as all children are - I attempted to make the world a better place.

Using a blank doll my nan had made me. Sometimes I sprayed it with lavender so it would not have nightmares or be eaten by monsters or I got lucky heather from the gypsies in Romford Market - they would never let me pay for it, those ladies in their black long skirts and crinkled eyes.

The Blank Doll who had no other name seemed to move about - a quirk of memory or childhood or both - it was rarely where I'd left it. But I lived no horror movie, there were no blood stains, only coffee splotches turning it a brown in places. It yellowed with age. I did not draw on it, to do so would have somehow defined it, imprisoned it, make it something and nothing rather than nothing and everything.

It scares me and I love it. The Blank Doll filled with sand that my nan gave me.

When I was sick with Jean's pregnancy a lady in at the same time asked me if I believed in voodoo, I hesitated and I could not answer - she thought I was maybe the victim of voodoo, with the problems I was having, she had many scary stories of women over Ilford way having their unborns stolen from their bellies. I thought of my blank doll, I think my dad found it for me - and I felt better, it's hard to admit with the science background but when I am emotionally stressed I fall back on the old superstitions and the comforts and so if there was voodoo I had my blank doll and it could be counteracted because my blank doll is me, it is my enemy, it is everybody and I love it and I care for it and that is a shield and a net.

I told you it was silly, just a little memory that got sparked by something today and I thought... I should share this before I lose it again.

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 🙂

A Stranger Dream – Virtual Launch Party (by sarah)

I am a poet, I am an artist, I am many things some of which seem contradictory - after the head bang last year the question of identity reigned large in my vision of self - not just my identity but everybody's and societies reactions to identity issues - so I started working on a series of images.

I was learning how to draw again and the ideas were appearing faster than I could create them, I spent 3 months working on the visuals for A Stranger Dream. And mainly I have had positive feedback though some people do hate the style and that is fine it is stark, it was meant to be.

But what is A Stranger Dream? Well for a start it is not A Stranger Dream it is A Stranger Dream: Love but it's not it is

Love: A Stranger Dream...

or both or neither or something...

It is a non-linear visual poem on identity, gender, our place within family, our concentric non-ecludian intersecting and exclusionary circles of all the cultures of us - it is the distorting mirrors within our own heads - the fitting and the not fitting - the fires within.

I know it doesn't look it but it was a hell of a lot of work.

Then someone said "it says colouring in book to me" and I thought... why not?! I thought people colour to relax, to sort thoughts, to just be themselves and that is fitting - plus colouring in book is on the list of to-dos and I have been producing colouring in sheets for my kids workshops for ages.

So I started by popping the images up as individual sheets for download and colouring - they are still there and they are free.

Then I made ring bound ones at home for shows and events... people far away started asking how they could get hold of them so I have created a colouring in book complete with purple spine and title box because... I am the Purple Poet!!!!

Here is a picture of the spiral bound ones at The True Believers Comic Book Festival earlier this year.

And this weekend (April 22-14 2016) I am having a launch party - sadly I am only running a virtual one but it is going to be epic!!!

I will be pinging around the internet - of course hoping people will buy the book but as I said don't feel you have to because I put the individual sheets out there for free download and I know times are tight (having said that I need to buy more art supplies... to you know produce more art!).

There is a Facebook Event, a Google+ Event, a twitter hashtag # astrangerdream and my patreon account (which will have hidden extras in it for patreons only). There are also the blogs namely this one and Turquoise Monster which is my poetry blog 🙂 So I think that is pretty much everyone covered - I am hoping to do a little film thingy too but we will have to see how the laptop holds up!

The colouring book is already up on Amazon and Book Repository etc... it is appearing as £10 odd - I meant it to be roughly £7 if you've bought the £10 copy let me know as I have a little goody bag to post to you containing some lovely tie-in items 🙂 (yes I am trusting people to be honest here! Thankyou 🙂 )

Oh and there should be a gallery unveiling where people can post pictures of their colouring in - if they wish 🙂

There are going to be give aways but there will also be merch for sale and special offers etc... (sorry guys I would love to give you everything for free but I do need a new computer!).

I am actually stupidly excited about this and am even making myself an outfit out of the art work! The poetry cards have arrived and are beautiful in a way I was not expecting 🙂

Most of all though regardless of weather you buy or take for free or just look - mainly I hope everyone will be enriched by the work itself, it was very important to me whilst creating it. It's kind of an imprint of the soul, maybe a darker one than people would like but it is... something - I'm not quiet sure what.

I hope you will join me for turning the starkness into a rainbow.
