Crash, bang, wallop: What a power-down. But what hit the kill switch?

Re: Placement of kill switch and other quirks

Problem is, EPOs are pretty much required to be somewhere quickly accessible near the space they protect, and obviously you want access to it protected to the same access level as the equipment. Then door releases obviously should be located near the door, and in places where people turn the lights off, that probably should be there. However, putting these switches all together at least shows the user there is a choice to make - the alternative it an exit, and an action to perform (release door/turn off lights) - if the user glances at one lonely switch, they're going to press it, so if their gaze falls on the EPO rather than the one placed not quite close enough, they're just going to hit it, with autopilot engaged.

Molly guards, and putting EPOs out of direct sight line are options in some locations, but other times, local or national regulations prohibit them

Re: Ah, the carefree days of yore

We are a two-dyson household. Mine (upright) has done sterling service for years, including not infrequent uses where I should use a shop vac. Mine benefits from an (easy) stripdown and cleanout every year or two. OH's cylinder one properly died, but as most of the cost seems to be mechanical design, replacing the whole motor cost me I think £25 (turns out I could just have replaced a brush, for even less), a couple of quid for a long enough driver (was probably torx, and too narrow a path to use an extender bar) and pretty much minutes to disassemble. Got a proper clean at that point too, which certainly did it no harm.

More recently, I was impressed by their adverts, and what they didn't say. Finally dawned on me that 'cordless is so good we no longer make corded' is another way of saying 'the EU can't police our motor power (whose methodology we disagree with) if we're drawing it from a battery'.

Re: Oh dear, a fan

Without a strong plan for a sufficiently low-power display that is still large and legible enough, you're going to end up needing a power socket for that part anyway. Even keeping within the higher currents provided by the later specs, your switch may be limited to how many can be supplied at that current, vs all 12/24/48 ports at a lower standard.

Re: The guy who set up that rack

> Most rack mount keyboard/display units have a hinged or flexible arm just for this.

It did take manufacturers several decades to get to this point, and neither low-end kit, nor reassuringly expensive boxes were necessarily quick to join this trend. Not necessarily feasible to have everything secured too, when a rack's keyboard would be moved between servers at the top/middle//bottom of the cab. Especially in places which didn't have the budget for expensive serial console servers (only for a moderately expensive proprietary keyboard).

Re: Question:

Software raid has a much better chance of keeping up with your needs, especially since there are fewer instances of spinning rust, and the related paradigms that host cards were built with, and (except at this sort of scale) we have enough spare CPU on the side to manage it, rather than having to offload it to a separate processor. But at this scale, you wouldn't want to fund the development of a controller card powerful enough, given how few units would ship.

It's a great safety feature where it make sense - why make it a possible failure mode when there's distance and load to accommodate doing it that way. But whether it's something like a simple high density data centre it becomes unworkable, and then literally impossible when you require diverse power feeds to even a single piece of kit for resilience.

East Midlands network-sniffer wails: Openreach, fix my outage-ridden line

the hatter

<quote>I don't, but that is irrelevant. If the issue is with the provider/Openreach kit there is no charge. if you have created the problem you will be charged. Not rocket science</quote>

But that's not how it works. More like one of these outcomes

(1) if they detect an issue with the provider/openreach kit, there is no charge.

(2) If there is a problem with the provider/openreach kit but they don't spot it, you get charged.

(3) if there is a problem with your kit, you get charged

(4) if there is a problem, and they can possibly blame it on anything other than their kit, regardless of being able to provide any proof, you get charged.

(5) the intermittent fault is not occurring when they attend, you get charged.

How many times would you like to pay BT £180 or whatever it is, for them to continue tell you simply 'it's not our problem' before you can finally find an engineer to actually diagnose a problem, that's happening when they attend ?

I doubt most reg readers have a problem with (1) or (3) but there is a strong incentive for openreach to push engineers not to try too hard, as then they get paid, and there's a strong incentive for engineers to close tickets ASAP because then they can get onto the next job.

Mostly they're not being nokia, the handset maker that owned the world.

Nokia died, but what remains is doing alright, considering.

For a long time, there was a viking-direct domain with a website that claimed to supply all your horn-helmeted, nordic raiding needs, despite several attempts from a certain office stationery company to claim the domain had been registered in bad faith. Long before many UDRP and arbitration policies, or even scarily long domain registrant terms and conditions, and the owners were quite happy to do enough to keep the corporate lawyers busy trying to work out a solution, it was a long, entertaining saga.

Re: Eh?

Hard to know without the details, but there are still a lot of companies who think that because you paid $10 for the domain, their offer of $200 is just far too good to have any reason to legitimately decline. My guess is that (at least without the risk of the french government just seizing it) there's half a dozen entities who would offer substantially more than than the government did, and that is it's market value. That's the value in forward thinking and planning.

Spotify wants to go public but can't find Ed Sheeran (to pay him)

the hatter

Re: If Ed Sheeran is feeling hard up...

Surely you realise the problem is not just the few at the top of the tree, those owed 4-, 5-, 6-figure cheques, but the thousand or millions of other artist, each owed maybe $100 from a dozen different companies all working this way. They should have to and shouldn't be expected to have to them spend more time and money to scrape together what the companies already know full-well that they owe.

Few things I hate more than having to spend half an hour of my time to (probably, or sometimes only possibly) get my hands on a refund worth maybe an hour of my time. But in this case the only reason these companies can stream the music in the first place is because they agreed to compensate the writers in arrears, yet they don't even make good on that obligation; they know they owe Ed $0.001 the instant they start serving the song to a new user, would they prefer to have to make each payment before bing allowed to proceed ?

I don't look forward to the EULA for the summarising site. Would have to be some pretty strong language to avoid them becoming liable for consequences occurring between the precise language in the original document and the dumbed down version provided. Either that or it'd be plainly-written and simple enough for even a budget lawyer to take down in court, for the intermediary to be liable for many, many huge sums of cash, and then go out of business.

Re: seriously??

And how does that NZ$80-120 compare to your hourly rate, given that trying to disinfect and verify it's gone is something you can spend a long time on ? Even in a small company if you can show the person with the chequebook that it's clearly saving money, they should either scare up the cash, or you should look to find somewhere who will be able to pay the next payroll.

Also, yes, the possibility of the drive firmware being tampered with by a virus is now non-zero, so nothing you do through the SATA interface can be trusted absolutely, including reflashing the drive's firmware.

Yes, the cost of hosting some DNS records and doing a bit of email forwarding is vanishingly small, and even smaller when you're already doing the same for eleventybillion other domains anyhow. Better they have larger customer numbers, and that your laziness will net them some loose change, next year rather than their competitor.

Stickers emerge as EU's weapon against dud IoT security

Stop

Re: I want only one sticker

One part of the problem is that even with source, it can't necessarily be easily updated, or even updated at all. Just because you can coerce your hardware to accept an update, doesn't mean the other owners could. I think you'd at least need a sticker for how to update - automatic, prompted, does it need you to run a windows executable, or to insert a usb key, does it need to have open internet connectivity. Step two would then inevitably be can you roll back an automatic update, when the manufacturer ships you an update that breaks functionality you use.

Facepalm

Two into one does not go

You'll probably manage to get one strand of PIC through the nozzle and slot, but no chance of getting both strands. If you find/make ematches with finer wire than you generally see, you could thread two matches into the motor, one higher than the other, for redundancy, with a scrap of blackmatch and a scrap of PIC. You'll want to be pretty sure there's enough room for all the wire to be spat out past the nozzle when the thing lights though, else it'll be much more spectacular than intended.

Baby hybrids not so cute

It'd be a fun final year project to come up with a decent, low mass-fraction hybrid system of that diminutive size, let alone one that'll reliably ignite remotely after it's ascent. Good luck to them if they want the challenge but I can't see hybrids being a magic solution - they could mass-optimise the solid for a lot less research time/budget if it's that critical, but a hybrid intrinsically requires more parts and infrastructure and they only scale down to a point. See, for instance, the smallest Contrail motors - 38x400mm for a G100/123/130/300, Skyripper motors - 29x300mm for a G63 or 38x400mm for a G125, the MicroHybrid project - 24x140mm for a D with a truly terrible mass fraction. At 32x150mm the G12 is just metal tubing, nozzle and bulkheads, everything else is fuel; the hybrids are all this, plus injector assembly, ignition system, fill mechanism, with the tubing being twice as long/heavy - that's a heavy penalty to overcome.

Just being greedy

Those USAians are just being greedy and unimaginative, using 'america', 'american' and so forth when those words cover 2 whole continents and the people of many countries. There have been attempts to adopt more specific terminology, but they never seem to get very far. Even sticking to 'united states' doesn't work, as using that for the USA upsets residents of the United States of Mexico, just to the south.

Mobile phones to get universal charger

the hatter
Alert

FUD

Apple's not the only company that makes use of extra communication lines - it's good news for nokia and lesser phone users who face a range of barrel-type 2-pole connectors, but for example SE phones have used the same multipole connector for many years, so it's not hard to locate someone with compatible wall, usb or car charger, anyhow. I'm in no hurry to see a second, redundant connector on my new phones, and definitely would be peeved if SE changed their current standard to accomodate the extra connector. Replacing the other wired functions with bluetooth or other radio options is hardly power-efficient.
