House Maths

So, we’re moving the fuse box electrical panel (and replacing the shonky crappy old panel. I’ve spent this morning sat working through this document that allows you to check the rating required for your service. I’d been thinking we might need to go up to a 300A supply, but it seems like 200A should be fine, which is pleasing. This is probably because the stove appears to be a fan-gas oven, which confuses the pants off me.

So the electrical loads that would normally be consumed by cooking stuff have disappeared into the gas. Which helps.

The sums work out at 96A which seems low to me, but that’s what the maths says. And I guess we normally charge at night when other loads tend not to be in use, so it probably works out fine.

I’ve also been trying to do load balancing. This whole 110v m’larkey makes wiring waaaay more complex.

UK: Incoming power -> RCDs -> Bunch of ring mains (lights, sockets, some single runs to specific appliances). Bob’s your uncle.
US: Incoming power -> Breakers of lots of different flavours -> Many spurs that all have to be balanced so that each of the two (120v) legs of the 240v gets roughly the same current draw + 240v loads that pull off both. You may be able to get an uncle called Robertish if you’re lucky.

So that means sitting down and trying to work out what groups of sockets and appliances are ‘likely’ to be on at the same time and then trying to organise them. Without just generating a billion different circuits. Then add in my desire to keep lighting and electrical outlets mainly on separate breakers (not required, but preferable). Then add in code requirements for specific areas to have specific kinds of breakers, or the dishwasher to have it’s own separate circuit… which it probably needs anyway in terms of power demands, but still…

…gah.

Of course this might all be punishment for the pre-regulation the-entire-kitchen-converges-on-one-socket design that I left in place in the first house I worked on in Bristol. I didn’t *make* it that way, but I didn’t fix it either. Just shoved all the wires back in the back of the socket and said “yeah, that’ll work”. I suspect it got fearsomely hot if you ran the washer/dryer and the oven at the same time.

Anyhow, since I’m not going to be doing that again and this is to be better planned, then I’ve spent some time on it. Hopefully it will work as recent calculations mean that I think I’m wiring the panel and just getting someone else to do the actual moving of the service / installation of the weatherhead… Technically, we could do that too, but I value my hands and my life :)

At any rate, I’m planning to submit the permit today – if we get the Rav back in time (it’s getting a new driver’s door lock, the old one having died).

In other house news, the smell of urine seems to be decreasing. We’ve removed the chipboard that covered the lounge, the hall, the kitchen and one bedroom. All that’s left is a bit of chipboard under the kitchen unit that we’ve not yet removed, the back bedroom and a small front cupboard. Spraying near a full bottle of urine odour remover onto the worst staining and the front step – along with a moderate amount of vinegar – seems to have helped too. I can now go in the house without wanting to run even when the windows have been closed. It just smells of musty old house and crawlspace.

Hopefully when we put down the vapour barrierey underlaymenty stuff that will resolve it completely. Although we’re planning to replace some of the worst car decking with new – and there’s one section which has broken.I’m guessing it’s rotted away under the end of the bath… but when I was lifting the chipboard I levered against it and it descended rather than the chipboard (with tile) coming up.

Pics on flickr as usual.

And in other, other news, I fell for a scam.

It took about a minute for me to twig and undo it, I think. About half a second for me to go “oh, you fucking idiot” and then the rest of that minute in a panicked google search and settings adjustment.

I listed our Insight on Craigslist, then got a message from someone saying they were interested, and could they call. Then I got a message saying that I needed to enter a two digit authentication code to speak to the craigslist person. I was somewhat suspicious – but after the person had tried a couple of times and I’d got messages each time I thought “well, what could I lose – I’m giving them information they’re giving me”. Apparently – this is a means of getting access to your phone number because when I entered it I got a Google Voice message – and allowing them to use it.

Thankfully, the answer is here. So within about half a minute I’d reclaimed my lost number. I’m hoping that the dickhead who did it didn’t manage to do anything useful with it.

After about 15 calls from the irritant, (s)he seems to have stopped. But it’s just f’kin annoying. I also am feeling a bit pissy because the Honda Forum seemed to think that the price was reasonable for the car, but now it’s been on there for a week I’ve had nary a bite. This may mean that all my sums about us replacing the car with an EV have to be reworked. If we have to drop the price of Insight to sell it…

Feh.

And in other, other news, I realised I should have ordered a smaller shift key when I ordered the keys for my keyboard. I did a test assembly of the kit which went fine, but I’ve not soldered it yet because I need the key tops to ensure that the layout I’m planning will work with the keys I’ve bought. It’s still very pretty though. It shall be super pretty when it arrives.

I just need to etch the CTL logo into it.

CTL terminal (in very fetching orange and black)

I just wish I could get an orange fabric covered curly keyboard cable to use. They don’t seem to exist :(

Tales of the Pinebook and Linux fun

So, I’ve continued to work on making the pinebook a comfortable usable device. It’s been a bit of battle – my mail server has some quirks to the way it’s set up which meant that it took me quite a while to get it working. I’m still having issues with another mail server I use, where I’m not sure if it’s me or the server. My lovely friend, who’s the Admin, has sent me some stuff, and I’ve sent her some stuff, so hopefully I can get it worked out.

I ended up doing my first build-from-source in quite a while today, so I could have Sylpheed, which is (apparently) a nice lightweight mail client. Certainly it seems pretty good. Can’t work out how to force it to allow certificate.

It’s fascinating (and at times a little frustrating) using the pinebook, because some stuff clearly taxes the hell out of the processor. I rarely log onto Facebook, but wanted to to grab something today and wow does that suck.

Still, it’s demonstrated some things for me – like the fact that my Linux server is set up right, it’s my Macbook that’s being a dick about connecting to it. I don’t know why – but the SMB share will only connect as a guest, not as a user. It fails to authenticate if you try and log in as an actual user. I’ve not yet had a good look as to why though – but since the Pinebook just happily connects (when I give it the username and password) then I”m going to point my finger at the Macbook.

And yeah, otherwise it’s a handy laptop that I can drag around and not worry too much about. And while Linux on ARM has proven to still be a bit of a pain in the arse (e.g. Telegram, which I’d like to run, is only available compiled for x86 Linux). It’s superlight and the battery life isn’t bad either.

It’s also finally nudged me into upgrading logitech media server on the media server, which, after the last upgrade had developed an irritating bug where when you added tracks to the playlist, or even just pressed play, it tended to make the squeezebox crash after a few seconds. Loading the web interface also seemed to take an age, too. I’d not got around to nosing at that problem, but it turns out that there was an update to the update which seems to have fixed it.

So yay.

Danger, Will Robinson!

Danger, Will Robinson!

I have fallen into the dangerous territory of the mechanical keyboard. See, many years ago I had a rather nice IBM keyboard which died. I can’t remember how it died. It probably got run over by a steamroller, or somesuch (I think it got knocked off a desk and landed key side down on the prongy-footy-bit of a wheelie chair).

At any rate, I loved it, but eventually it made my poor hands hurt when I was doing technical writing. Also, I tried taking it to my office and had to bring it home to prevent my summary execution for the clickety-clackety-noise of it distressing and distracting my colleagues. Anyhow, so first I discovered tenkeyless keyboards, which are nice. Especially if you have a dinky little numpad to go with it that can float off and be moved around as needed.

Mhm.

Then I discovered pretty keycaps.

And while I knew that mechanical keyboards were “a thing”, I’d not really realised the extent of “the thing” that they are. And I can feel myself being sucked into it. Mainly because I thought “oh hey, wouldn’t it be fun* to build my keyboard myself”. Why I thought this is probably related to my dad, who had to build every damn bit of the computer himself, and made a rather fine hardboard cased lilac coloured keyboard. And I am always rather sad that I got rid of that in one of the tidies. I mean, it wasn’t useful or anything, because it was a terminal keyboard for a terminal he built, which I no longer have either.

But I rather liked it.

And then I saw the T0mb3ry SA Carbon keycap set. And I spent far too much money on it. Which is silly, and I couldn’t work out why I liked it so much.

Then it came to me. It reminds me of the old CTL / ITL keyboards my dad used to bring home (scrap ones). I was aware that it kinda reminded me of early 80’s computers, but it’s that whole orange/black bone/black combo that makes me think of the Modular One system. I’m not sure if those keyboards came from Modular Ones, or if they were from some other CTL / ITL machine.

So that explains that.

So anyhow, I’ve ordered the keycaps, because I’m weak and they’re pretty, and I’ve also started to nose around for a mechanical key tester (one with a USB connector so that they can actually serve a purpose as a num pad later), and then I’ll need to work out if I really want to fork out the cash for a keyboard kit, or whether just buying a keyboard and slapping the keycaps on will do me.

 

In the years before…

…when the internet was young[1] I used to collect the odd video. You’d find some bizarre things out there. They’d be uploaded in all their 320×240 glory, usually in mpeg or flv format… It’s not a massive collection, and mainly these things can now be streamed on youtube in vastly higher quality. But I have discovered since resurrecting my media server that something is f’ked up in the flv player on our media player. The speed is hideously variable. It actually makes me feel quite nauseous to listen to any of them. I’ve also got some videos that were sent to me by a nice person who worked at a record label – when they were being sold / closed.

Ugh.

In other related news, as you might gather the server is up and working. The files are mainly where they belong. Some stuff seems to have disappeared and will need to be reripped :(

I want to add some stuff for privacy purposes… I’m gradually trying to move towards behaving like the privacy aware citizen I am, but having installed a VPN I found I couldn’t get either Plex or Subsonic working. Trying to persuade port-forwarding to work with a VPN is quite challenging. I’m aware this would reduce the security of the connection, but… I am trying to hit a nice point between security and insanity.

[1] well, ish.

Just a little bit…

Because Linux’s move command is actually copy-then-delete if it’s not within one partition, I have to do this file shuffling in multiple chunks. Which means selecting a group of files, saying “move them”, waiting an hour while it does that, then selecting more files and doing it again. It seems to be working, so far, and I’ve done a teeeensy bit of tidying of the files on the way past (I really need to either sit down and suck-up tidying up this server, or obtain a minion to do it for me. Given the latter’s beyond unlikely, I think the former will have to occur at some point).

What I really need to do is borrow a few 4Tb drives, shuffle everything onto there, then set up a nice raid array, and shuffle it all back. It’s 11Tb worth of data (well, about 10Tb plus a 1Tb install disk, which is, yes, a ridiculous install disk, but it was a data disk until it got ‘too small to be useful’). But I don’t really have the cash to throw at a new multidisk array. Not if I want to get an EV to relieve my poor Minor of it’s 60 mile commute each work day. I don’t mind taking her some of the time, but I don’t really want to destroy her. So I think, for the time being, we’ll just have to put up with things being the way they are. Mind you, at least they’re now in a case where the disks are all in proper bays. That’s quite exciting. And I can take disks out without disassembling the entire PC.

Still as I watch file 481 of 1,702 move from one directory to another at a whopping 52Mb/sec (the other board was faster, when it worked, it used to hit about 80Mb/sec – then die), I can’t help but think of the fantastic musical treat that popped into my head as I considered that I had to move the files just a bit at a time.

Sorry.

So far, today has gone better

I spent this morning watching Big Clive tearing down a cheap USB charger which, for unfortunate part-failure reasons – passed mains straight through to the USB port. Sadly for the makers, who actually seem to have given a fig about design – and who’ve actually gone to more trouble than seems common to build a reasonable piece of kit, they were let down by a parts failure.

Anyhow, the thing is gently soothing to me, reminding me of sitting reading while my dad would strip down and repair electronics.

So it finally got me motivated to try and move the cable from the knock-off apple supply (which said “MagSafe” but actually appears to provide the full 85W regardless of whether it’s connected or not) to the old apple one I had which had a faulty cable. I’ve got an array of toys here now, most importantly in this case my temperature controlled iron which was complete overkill (and proved I need a different tip for it – so I’ve added some new tips to the selection of stuff that I’ve got in my AliExpress cart…for later).

Anyhow. The general impression when I stripped the knock-off one down was that it was poorly made:

IMG_20160412_134512

Although I didn’t get in to actually looking at the design. After a fair chunk of time and a bit of a battle I managed to desolder the apple cable and replaced it with the one from the knock-off – which seems to be working nicely. The poor apple brick is now held together with tape tho’.

I also trekked out to return the case I bought from Blinq – they turned out to be very nice people, giving me a chunk of refund for the massively delayed motherboard delivery – and promising to refund the money from the case that was smashed in transit.

Also, the nice guy at the FedEx place taped the box shut for me, when I asked about tape :)

Then I headed over to what has become my favourite computer store and started peering at cases – explained my predicament (i.e. it normally lives out of sight, so I want something that’s functional, has lots of bays, and is also fairly cheap) – and they produced a second hand case for $45. Bargainateous, if you ask me.

Having got home I commenced the joyous task of rebuilding my PC using a new motherboard but the same everything else – not really an upgrade, more a side-grade.

IMG_20160412_123438

Once thrown into the new case, it booted straight up and seems, surprisingly, pretty happy. I’ve now started trying to sort out the pigging mess the file systems had become – with the spurious resetting problem seemingly better (it just moved 160 Gig of files in one go, and before that another 90 Gig), it’s looking like it might be possible to at least get it working and the files back where they belong. Once that’s done I can start contemplating the possibility of sorting out a raid array for it.

Creeping Americanism

So, my card holder finally no longer contains my British bank cards. They’re now securely & safely stored away… I’ve not quite had the heart to remove some of the loyalty cards from the independent retailers in Bristol. But the transition plods on.

I more or less remember to say pants at work, and ask them to get up on the gurney (although gurney still sounds odd coming from my mouth). I still fuck-up though and say plaster, not band-aid, which confuses the hell out of people. And I continue have no clue about degrees Fahrenheit. Thankfully, most of the thermometers at work will do the conversion for me when patients ask (and we work in Centigrade anyhow).

I can say gas station without feeling too silly, although in my head it’s still a petrol station. At some point I’ll switch and it’ll no longer feel unnatural.

I’ve finally got around to contributing to saving an NPR station (KPLU), and I think I may finally have managed to waterproof the front of the minor against the PNW’s weather (no guarantees yet, but it wasn’t wet after two heavy storms). All gradual signs of settling, I suppose.

On the topic of the Minor, the back is proving a little difficult to sort as it turns out most of the reason it’s had water in there isn’t that it’s been running down through the many small holes I’ve been sealing. Or at least, some of the reason is that. Some is that the trunk lid (no, that still feels wrong, the boot lid) actually fits pretty terribly. It’s a glassfibre replacement for the original – I went with glass fibre because the metal ones rust through due to a fabulous water trap.

Issigonis was good at many things, and apparently designing mud and water-traps in his cars was something he excelled at.

Anyhow, I remember when it was installed Jonathon commented that the first one was a terrible, terrible fit, so they sent it back and got a replacement that was merely a bad fit. It looks fine until you get close in and then realise that the panelgaps are all wrong, and from the underside you can see a gap through into the boot (trunk).

Added to which, the seal – which is held on with glue – is peeling off. So I need to find me some impact adhesive and see if I can sort that out.

Also, when we get back into dry weather I need to see if the vinyl repair kit will repair the tear in the front seat. Although I might want to do that when Kathryn’s here, because she’s much better at mixing paint colours, and I need to get a match for the blue of the seat from the selection of not-matching colours provided.

In other news, I gave in and ordered a new motherboard. After a full 4 hours of attempting to get around the fact that my motherboard is buggered, I admitted defeat. Every time you try and move a large quantity of data it falls over in a heap. I considered finding the code for my single byte-at-a-time read-write routine from the RiscPC (which was painfully slow, but did something handy at the time), then realised that I was clearly insane. All the disks report good health (although I’ve had very sick drives report everything is dandy). It does it whether or not you’re using the graphical system (which seemed to make the problem worse at first, but actually seems not to after more playing).

I worked out eventually that the reason it was going quite so spare was that I’ve moved a bunch of files around and both Plex, Logitech’s media manager and Subsonic were all simultaneously attempting to catalogue the roughly 8-9 terabytes of data.

I did pay for the speedy 3 day delivery of the motherboard…which I’m peeved at myself about because I’m not going to be around to install it until next week anyhow. I should have thought about that more. I was previously peeved at myself for forgetting to pay for the extra fast delivery on the case…before realising that I should be grateful that I forgot!

Now we get the excitement of seeing if Linux will nicely handle the sudden change in all the underlying hardware, or if I get to play ‘lets install everything again’, which is a fun game for one (annoyed) player. It almost invariably boots when I do shit like this, but usually there’s some problem that persistently rears its head and causes me to end up renewing the installation.

My main hope is that I can, at least, get away without buying any new hard disks for the moment. I mean, really that’s the bit I’d like to upgrade. I’d like a nice Raid 6 array, but it’s tricky to do so as things stand, because pretty much all the disks are full. And a complete state. Although it might be a possibility with careful shuffling. Hrm. Also; would involve expanding the partition after the installation. I forsee many complications… but it’s worthy of more contemplation. Might have to spend a moment looking at the state of the disks and then playing with them before I get into reinstalling.

Anyhow. House wise we’re still flailing around hopelessly. We look at places, debate whether they’re too far to really be liveable, fail to make any decision on where we’d want to start a business, and basically are having a bit of a crisis of ‘too many big decisions and not knowing what to do’. We’ll get over it, but it may take a little bit.

It lives! At least a bit.

So I went back to 4th Dimension Computers because the insurance co were unhappy with “it’s dead Jim” as the reason my PC was dead. I’d replaced the power supply when I got here with a brand spanking new one, because the one in it was irritatingly only rated for 240 volts.

Having traded in the new supply, the machine refused to boot. And I’ve given away / recycled all the other supplies I had which were, to be fair, also only rated at 240 volts.

So anyhow, I get there, and they’re very lovely and he pulls the plugs and tests the supply. Dead.

He grabs a spare supply from the shelf and tests it. No boot. Computer’s still dead. He tests his supply – dead.

He gets a third supply and tests it before connecting it… working. Connects it and… yes, the machine works. Which demonstrates that having spares around is handy. Unfortunately, now, having been apart so many times I’ve no idea which drive goes where in the case. So although it powers on and detects drives, it can’t boot. Which means I now need to create a rescue USB stick and try and correlate which drive is which to which port they were on before, then switch them around accordingly.

I can see this being a fun game.

…of course, to do that I need several things. A monitor and a keyboard would be a good start. It would also, probably, benefit from a USB WiFi adaptor, given that it’s not got a wired network to plug in to…

Yay! Unyay!

I turned on my RiscPC and lo, “Thwooop” it went.

Up popped:

RISC OS 4.02

And then things went a bit wrong as it ran out of memory (it used to have 64ish meg, now I think it’s got 12 thanks to death-of-battery), but it made it to the desktop.

And then I discovered that like many modern LCD monitors, the one I’m borrowing to test things has little to no knowledge of ancient ‘puters. I think I may need a VGA to HDMI converter that’ll handle any input, because I suspect it’s switching to something like 50Hz 640×480, or some other hideous mode, and the monitor just cheerfully says “Mode not supported”.

After a few abortive attempts to play games I thought “ah, but what about Xenon 2! That might work”.

*Splutch*

Oh well.

Still, the 115v mode on the power supply seems to work, there were no hot or burny smells, I think that one counts as a win.

Smooth as a grit sandwich

So I checked over the media server, spent ages making sure all the drives were plugged in correctly after shipping it over and then I turned it on. Well I tried to turn it on.

Dead.

I checked it over and made sure that all the connectors were definitely well seated, that there were no untoward bits of crap floating around, that nothing was obviously amiss.

Dead.

I stripped it down to just the mainboard / processor / memory / GFX card.

'It's Dead Jim' -- Bones McCoy

I stripped it down to just the mainboard / processor / memory.

So that’s another thing I’ll have to claim on the insurance.

Sadly, the phrase ‘woefully under insured’ springs to mind. When we got towards the end of the insurance items list we were starting to realise that we were running out of money to actually ship the damn stuff. So it’s only insured for around $400 (most of the other computers I shipped over I could ask lovely John to find a free replacement for, and then just ship over). That’s not enough to replace the hard drives in it, because it’s got “quite a lot of storage”. I’m thinking that if I replace the mainboard, processor, memory and at least one HDD I should end up with a working machine. Hopefully, whatever’s killed it didn’t kill all the hard disks, otherwise I will be a very, very sad bunny.

Thankfully, the cost of parts for an FM2+ machine isn’t way high, so even with the fairly low level of insurance I should actually be able to get a working machine again. How quickly, though, that’s another entire question.

I am, however, considering the possibility that it might be time to get a new case while I’m at it. If I’m throwing a new motherboard in, I might as well have a case that actually can hold a few more drives to put it in.

It’s quite frustrating. Not least because I was really looking forward to having our video server back online, and listening to podcasts again.

Tomorrow is, I think, claim day.
