Computer problems

  • Finally, finally.

    So, I’ve been crossing items off a list that doesn’t really exist except in my head.

    I’ve fixed the dishwasher, I think. It’s working at least and not tripping the RCD. The noise suppression capacitor on the mains appears to have been the fault… it’s quite nice to throw things in and have them come out clean without worrying about the fridge.

    Kathryn and I have finally replaced the bit of wood that belongs under the last cupboard in the kitchen:

    Before:
    Untitled
    (Note the little teeny gap at the end where it was cut to the wrong length by our kitchen designer)…

    And After:
    Untitled

    That teensy tiny fix has been hanging around since a few weeks after our kitchen was installed when he turned up with the corrected bit. And it’s quietly bugged me for ages.

    I’ve repaired the earth lead on the anglepoise Kathryn uses as a bedside lamp. That has been broken, err, for years.

    And I’ve also filed my paperwork and cleared some of the office in preparation for our Thanksgiving which, we’re planning to hold in the LibrarOfficeSpareRoom. I’ve registered at the GP for online access (and sorted my repeat prescription), I’ve checked the deeds for our house and found that our fence is, apparently, shared, and that we’ll have to share the cost of rebuilding the disintegrating wall (oh woo). At least, according to our deeds. Oh, and I’ve swept the stairs.

    I’ve also, I think, killed the RiscPC. It does power up now but behaves incredibly erratically, so I think I need to fish it out and see if the power supply is dead. The supplies on them were always a trifle sketchy, so I’ll have a look at some point. Also, the CMOS battery in it has definitely died, this I can deduce from the fact it thinks it’s 1900.

    What is astonishing about it is how quick it still feels. As soon as you try and ‘do’ anything, the fact that it’s nearly 20 years old becomes rapidly apparent; the machine grinds and churns; loading webpages for example, is not a quick experience. But when you do OS based stuff, it’s FAST. Ah well, part of the reason I loved the OS then was how light and quick it was.

    Anyhow.

    I should finish my cup of tea and get on.

  • Distractions

    So I had a momentary distraction (that lasted about an hour). I wondered if, for our upcoming Thanksgiving, I could coax the RiscPC into providing us with music. The only slight problem was that the RiscPC is 18 years old, and won’t talk to the network properly. It has internet access, of sorts. Despite sporting a processor upgrade (233Mhz StrongARM!) and a mighty 32Mb of RAM, the poor beastie has a bit of an issue with the trifling problem when it comes to accessing the network shared files.

    In a final moment of distraction I’ve managed to find ‘SunFish’ which I’ll give a quick go too, but I’m not wholly optimistic. Also, it turns out it’s way noiser than I remember, although not vastly noiser than my Mac is these days…

  • Retest

    Done some tweaking and upgrading…. checking things are working, please ignore me!

  • Mini Triptych

    – I am becoming an occasional staff writer for Transport Evolved. Don’t think I don’t see the irony in that, I own a bike from the 1930s (pushbike), a 60’s car, a 70’s car and a pre-production EV. That said, I’m the head of The Electric Minor Project, so that probably has more to do with it! You can see my Staff Car Report up there, if you’re so inclined.

    – I keep getting lost down the rabbit hole with respect to our media server. It’s reached the end of hardware support for my chosen OS and I keep thinking, well, should I actually replace it. It still works… Anyhow I’ve been dinking and still go no answer, but am pleased to find I’m just as geeky as I always have been and am quite happy to spend an inordinately long time trying to work out what the cost/benefit ratio is of getting each processor. And how far back in history I have to go to get a decent one. And whether I’m better off getting an older-faster or a newer-architecture-slower one.

    – Our dishwasher’s died and it turns out I still dislike doing the washing up. I’m not sure how long my streak of ‘I will wash up every day’ will survive. Part of me thinks I should look at the dishwasher and see if I can fix it, but frankly, it’s 15 years old – at least – and is shorting to earth, only intermittently at the end of its cycle. Spares for it are, broadly speaking, unavailable. Leading me to conclude that I probably can’t be arsed to fix it. Which is terrible. And I am a terrible, weak person, but buying a replacement second hand one just seems much, much easier. Never mind.

  • Ah, the joys of 2000’s tech.

    So, our poor old media server dates from 2004ish. Although most of the hardware in it I think dates from 2003 (apart from the selection of hard disks). Last night, for reasons that have yet to be explained, the power supply circuit which feeds the upstairs and the ‘outbuilding’ tripped. I’m yet to work out what caused it because everything I can see is still working. Everything I’ve tried has come on without complaint…

    Except the aged media PC which perked up and switched on but declined to join the network. It has no attached screen (nor keyboard) so this afternoon I pulled it into the house and lugged it up the stairs. It’s fairly hefty being a midi-tower basically filled with cheap hard disks.

    I plugged it in and it passed POST and then sat at detecting hard disks. Attempting to coax it into setup made it just sit there more. Muttering dark curses at the lack of a UPS I rebooted it and just as I was about to give up, up came all the hard disks and lo it sat waiting cheerfully at a ‘I failed to boot last time, would you care for me to try a recovery mode’ prompt. A quick cycle through and check of the hard disks and it was back up and running.

    I suspect what happened is this:
    – Power went out causing a shutdown of an unfriendly variety.
    – Machine came on and went URK! I must check my disks!
    – Tried to check disks before booting but because there is a lot of storage in there and it’s not a very fast machine it takes a loooong time.
    – I gave up trying to access it because it wasn’t appearing on the network, powered it down… and then the rest is tedious.
    – First time I turned it on I was expecting failure so didn’t apply as much patience as I should have waiting for disks to be detected.

    Still, it’s making me go back to thoughts of buying a UPS. Even a dinky one that basically has enough power for the computer just to shut down politely, that’d be nice.

  • Best laid plans of mice and Kate

    So, I’m off on an ALS (Advanced Life Support) course in June. In my usual efficient, non-prevaricatory way I’ve left doing the online portion of the course…a while. I’d vaguely noted that it said that the learning management system would be offline for maintenance for a couple of days but hadn’t really taken much notice of when, exactly. Until today. When my plan for the day which went:

    – Paint
    – Dink on the net
    – Go out for nice lunch
    – Return and do ALS precourse
    – Drink tea, eat biscuits
    – End

    Fell over somewhat.

    I managed the painting; another coat of lovely red paint on the lovely trim. I’m now all the way around the upstairs door frames, which means after one more coat on that frame all that’s left is the trim that I can only prep and paint when Kathryn’s home (because it involves being ‘quite high up’ on a ladder at a slightly dubious angle) and the trim next to the stairs. I’ve even painted the loft-entrance.

    Oh, and patching up the paint on the wall which, as usual, does not seem to have stuck as well as I’d like despite the endless attempts to persuade it to (with plaster-prepping pre-paint stuff, dilute coats, and sensible long drying times). I’m never quite sure how other people get paint to stick to plaster (or if they really do), because while the vast majority of it seems to end up pretty well attached, if I ever put masking tape on paint (which it says you can) it always ends up pulling stuff off. Anyhow. Despite the low-tack masking tape, there were a couple of small areas where the paint’s been pulled off the wall. Some of that is fillered areas, and some of it is just that it hasn’t stuck at all to the plaster. I’ve got some paint from the batch that I kept ready for such an emergency, so I’ll clean the wall up, probably filler it to get it close to the level of the multiple coats of paint and re-prep it and then repaint those little bits.

    The red really adds definition to the upstairs. Or at least, Kathryn and I think it does. Everyone else might hate it. But we really like it.

    Then I set to on the Sepsis cards for work. I’d thought I was happy with the design, but looking at them today I just wasn’t. So I spent some more time modifying the layout before sending them off to the printer. I tweaked it so I could abuse business cards into being the sepsis cards. You can all tell me how much you hate them, but I’m quite pleased with them – in so far as they at least look different to some of the other cards we get at work:

    Sepsis front Unbranded

    Sepsis back

    It’s still not really to the standard I’d like, and the font isn’t quite what I was after, but given I’m not paid to do this, this is my own time, and my own money, then… well. They get what I pay for. The blue is meant to sort of tie it in to the NHS blue, without explicitly stating that. :)

    Anyhow, then I sent them off to be printed. All pray, I did online proofing, rather than taking it to the local Staples, because Staples didn’t seem to want to share their online pricing for printing full-colour double sided business cards. I may get back 100 awful, hideous, unreadable cards. But they looked fine in the preview.

    Anyhow, that done, I did my dinking on the net. Bought myself a network cable and socket tester (and it came with a free crimping tool, which is handy as I’m thinking of extending the cabled network down to the garage*). Anyhow, the excitement of that is I might be able to isolate what’s wrong with the kitchen network point and then I can fix it if I’ve wired it wrong in some way or get a new socket depending. I’m thinking it’s probably a socket because it’s definitely worked at least a bit before. Either that, or something’s eaten the cable, which would make me sad.

    Anyhow, that done I set to on the next problem which was going out for a nice lunch. Easy. Headed over to Hart’s Bakery…only it was rammed. There were no seats at the tables, so I ended up grabbing it and coming home which made me a little sad. I was looking forward to getting some nice coffee and chilling out in a space other than the house.

    Still, when I got home I still enjoyed the delicious bread, and then attempted to log on to the learning management system. And there it was. LMS unavailable until the 29th. ‘Bother’, I think is the word I was looking for.

    On the plus side, after some vacillating about how to spend my newly available afternoon, I headed out to the garden and moved the rest of the soil from the front garden to the back. Distressingly, the new pseudo raised bed astonishingly still requires more soil. I suspected as much, that I might have built a bed that required more soil than we have, but the fact we’ve put around 700 kilos of soil into the back garden (plus about 800kilos of gravel) and we’re still short is a little scary. I keep thinking that the amount of compost, manure, gravel, sand and plain old soil we’ve put in, and the fact that the excavated soil from the garage also went in should really have raised the garden up several feet. But it hasn’t.

    Anyhow, the soil moved, but distressingly inadequately filling the bed meant that I couldn’t do what I’d planned to do, which was put the veg / plants out that’re sat on the windowsill waiting for a new home. We shall have to pick up some more soil to complete the bed :(

    That having slightly failed I set to on another project, which is a mixture of creating a new bed further down the garden, and stripping the last remnants of the lawn off – and moving them to the tiny bit of garden that will hopefully become lawn. It’s right down by the garage and we’ll probably turn it into more of a meadowy affair, but at the moment it’s a mixture of cat-shit and weeds. Oh, and it turns out, potatoes. I yanked a mixture of potatoes and weeds out. Buried the cat-shit a bit, and then started skimming off the grass from the soon-to-be-bed and putting onto the soon-to-be-lawn. Uneven and lumpy though it is, it is a fairly effective (and cheap) solution (although we’ll have to put lots of raked topsoil and grass/wild meadow seed on to it to make it level enough). But it does make that patch look better, and it did so pretty rapidly. Still lots more to do there, though.

    But whilst I was doing it I slightly surprised myself by stumbling on what was perhaps once the edge of a border. It’s a little hard to tell; there’s just a line of bricks running across the garden – edge up – so I’m assuming it’s not a wall – although I’ll need to dig them out anyhow so I will soon find out. It’s quite near to the area of random, inexplicable concrete that was dug up when we started on the garden. I have no idea if it relates to that in some way, or was simply the edging of perhaps a war-time veg bed. It was sufficiently far under the mud that the grass looked quite happy, and I’d no idea that the bricks were there until I hit them.

    So anyway, that was pretty positive. Then it started raining, so I’ve taken shelter inside again….

    * Which leads to the exciting debate: Do I do it properly with armoured direct-bury cable, or do I find some spare old hose-pipe and run the cheap, nasty, horrid (alleged) cat5 cable I’ve got inside that. I’m largely inclined toward the latter, considering I’ve got bloody miles of the craptastic cable, and I’m not going to take it to the US, nor am I willing to inflict it on anyone else because I’m highly unconvinced of it’s actual twisted-pair-ness.

  • Impressively coordinated failure

    So, a little while back I noticed that one of the case-fans on the media server was in the process of failing. It was a shonky-ass glowing fan that I’d only connected a couple of years ago, because the server was running quite hot in the summer. I may have had it connected years ago when the machine was new, but I’ve not used it continuously…

    Anyhow, despite its relatively low usage, it’d started making graunchy noises. I wasn’t too worried. It’d fallen in to the ‘replace when it starts getting really noisy’ category because it’s winter, and the machine runs pretty damn cold in there. That room’s only heated to around 15 degrees or so, just to keep the washing machine happy, so I wasn’t too stressed.

    However, I got home today and eventually, having had my (nearly 3 hours) of sleep-deprivation prevention treatment (a nap after my night shift :) ) and sloped downstairs with the intention of, wait for it, painting my nails. Yes. Seriously. I know!?!*.

    Anyhow, I sat down, fresh tea on the table, flicked on the TV and asked the XBMC machine to connect to the media server. Failure ensued.

    I pulled up my laptop and said ‘Oh hey, laptop, what’s up with the server’ and my laptop replied ‘what server is that then?’. And so I sloped out to the server room and was met with the silence of a machine that is most definitely off.

    This is worrying, I thought, and then recalled that the server is set to power-off on all fan-failures. I poked the power button.

    *GRAAAAUNCH* went…several things. The known-sickly case fan appeared to sort-of spin up, then stalled, then started again. But while it was doing that there were other…nasty…failed fan noises.
    *THWEEEEEEEEEEEEEEEEEEEEE* went the self-test before I plunked it back to its happy-off-state.

    I pulled the server into the house. A little research revealed that:

    – The case fan is dead
    – The power-supply duct fan is dying (and making some very sad noises)
    – The power-supply’s own fan is dead.

    This is very upsetting, because the power-supply is only just over a year old (September last year it was replaced) – and I didn’t get the very cheapest piece of crap supply. Fortunately, I thought, I’d fixed the power supply that’d failed with shiny new capacitors.

    Throwing that in and whipping out the two sickly case fans, I thought, would produce a server that would at least work until the new fans arrived.

    Only no.

    Because turning it on with the shiny new supply led to the discovery that (I suspect) the somewhat rapid ‘FAN’S DEAD TURNING OFF NOW’ failure has done badness to the boot drive.

    Turning the PC on leads to the ‘I’m going to boot now, oh’ failure. And so I’m waiting for the Ubuntu LiveCD to come down so I can break out the FSCK on the disk and pray that it’s just that that’s died.

    So, my peaceful post nights reverie (watching Lost Girl and drinking nice things) has been destroyed. And. And. And my nail polish needs to come back off :(

    * It’s my Xmas work do tomorrow, I thought I’d stun them with actually painted nails. Although in all honesty, my nail-painting-skills are not what they once were, and I think it’s probably time to buy some new nail polish, because the stuff I just applied has roughly the consistency of porridge. Unfortunately, I can’t be arsed to go down to the chemist and get some more. It’s a shame, because I really like the colour.

  • I think our router may be melting

    So after the excitement of the garden yesterday, today I went and worked on clearing out/up in the garage so that we can get the new car (hopefully Thursday) in to charge. Otherwise we’ll be a bit shafted, really.

    After a good few hours work, I turned this:

    Untitled

    Untitled

    into this:

    Untitled

    Untitled

    Actually, the shelves went up (rather rapidly) as part of the tidying. You can deduce this from the fact they’re

    (a) Not strictly level
    (b) Made from crappy old offcuts
    (c) Put up using really surprisingly poor quality London brackets.

    I need to whip the stuff back off the shelves at some point because as you might have gathered I’ve not actually painted that section of wall yet. But with the car coming, as I may have mentioned, on Tuesday, I felt today was not the day to invest time in painting.

    I want to get some better quality London Brackets and put up some more shelving on that side, and possibly a bit on this side. I’d also like to spend some ‘quality time’ down there and see if I can’t actually produce something more like organisation (as opposed to randomly hurled on the shelves). Also, I should see if I can’t e-bay some of it, because there’s a lot of stuff there which is just waiting to leave.

    I have this horrible feeling I should get rid of the table saw, which would make it the most pointless purchase ever. I thought we’d do much more with it, but in all honestly it wasn’t really the tool that we actually required in the end. Getting rid of it would make a lot of space in there. The chop saw is also out on loan at the moment, which helps.

    I could also, realistically, get rid of all the chargers bar the ‘RAC’ one. I’m pained at the thought of getting rid of my ABBSAR charger – because I actually paid for that one – the others all came with the EV conversion stuff for my Minor. But the RAC one is actually probably the best of the bunch. Either that or one of the 12A Fast/Trickle chargers. They could all go on e-bay at 99p…

    It was hideously hot down there, not as hot as it was outside though… which made me doubly (or possibly tripley) grateful that I’d organised collecting the hardcore as an evening job. However, in the awesome coolness of Freecycle the hardcore turned out to be a mixture of stone and mortar from a probably 18th century free-stone wall built in Fishponds. Originally it would have been all stone but had been patched up with mortar over the years – the section of wall fell down in a winter storm and the owner, when it was rebuilt, had it done as a modern wall – with lots of mortar. Leaving an awful lot of stone left over. Originally the gap between the garage and the (one and only section of) lawn was to be filled with gravel, and the hardcore was just to make it cheaper, but having seen what we’ve got, it looks like we might well just leave it as it is, because the stone looks like it’ll be quite nice once it’s washed off :)

    In other news, with much effort and the use of a Mac app or two, the salvaged section of the car’s service timelapse is now here:

    For an experiment with timelapse it was quite painful (should have just got John in) – but despite ending rather abruptly (take it up with Lapse It which doesn’t recognise the camera orientation), and not having sound (because I was too cheap to buy a time lapse application which would add sound having had Lapse It fail, and O Snap also is not looking too clever at the moment).

    Unfortunately, whist the heat has led to lots of garden progress, swimming in the sea, and clearing the garage up it’s also coincided with our internet connection getting worse. We’re planning to switch provider anyway, because Be have been bought by Sky, it’s merely a case of getting enough tuits to make a round one. I may reset the router in the morning but for tonight it’s been painfully slow. The poor media server is also running in a very warm laundry room. I’ve opened the door for a bit this evening to give it a bit of a break!

  • Augh (it’s one word post day)

    So I checked, and there’s a bunch of CDs I ripped which have, for whatever reason, not made it onto the server. Actually, I think there’s a few that had not made it across and some which have got mixed in with the “ripped” pile. I just spent a chunk of time going through two of the stacks of ‘ripped’ CDs and have a veritable music of CDs (or whatever a pile of CDs is called) which weren’t ripped. And so need to be ripped. Feh.

    I need to go through the rest of the pile, and I need to double check that they’re not in the directory of just-ripped stuff (because I rip stuff on my mac, then transfer it to the linux server which has but one non-locally writable directory for reasons which were clear to me when I set them up – and then they get moved to the music directory in big batches). But I suspect they’re simply not there.

    The reason I know there was some sort of copying issue at some point is a few of the CDs have empty directories on the music server. I don’t know why though. Augh, really.

  • Nooky

    So, I’ve been debating a nook as a possibility to try and reduce my ‘looking at bright scenes at the end of the day’ habit. Apparently this is bad for your sleep, so an e-ink reader of some sort seemed a good plan. But after the experience with the no-so-Superpad (III) the concept of another unbranded low cost device didn’t make me feel optimistic for future success. So instead I looked at nooks and kindles and hacking of said devices to be more ‘useful’. The newer kindles appear to be a bit challenging to root, but the nook simple touch appeared to be a pretty good bet. And secondhand from the US it was only about £30, which also seemed a good bet.

    Having got one I can say I’m quite pleased. It’s not perfect by any means and it runs Android 2.1 which appears to be a bit of a challenge to get some things for, but:

    Nooky!

    There is Matriline from my greader, there’s an instapaper knock off for it, and after some searching I found an old copy of readitlater which should do for accessing pocket for my beloved.

    The e-ink screen is pretty nifty and the quality is pretty good:

    Nook running greader
    although I really want a ‘turn of all animations’ option for everything. Scrolling in greader’s a bit funky, but mostly works. I’ve another rss reader to try out at some point that’s meant to be more configurable. Still; I’d rate the nook fairly highly, especially given the price point and the e-ink display. So, yes.
