[23:37:35] <Runaway1956> That may be it, but I didn't try the call over wifi thing until I was aleady frustrated with Google Voice
[23:35:43] <chromas> your carrier and google voice take up the same spot in the series of tubes. there can be only one
[23:28:26] <Runaway1956> hours later, it still doing it's little whirly windows-like animation
[23:28:06] <Runaway1956> when I started it all up again, Google Voice doesn't connect
[23:27:52] <Runaway1956> I guess that should have some context - internet all but quit on us this morning, I shut off modem and router for ~10 minutes
[23:24:53] <Runaway1956> I've made four cell phone calls today, sitting on my arse in front of my computer
[23:24:09] <Runaway1956> and it works for some unknown reason.
[23:24:01] <Runaway1956> Today, I really wanted to make a call, and tried it again,
[23:23:48] <Runaway1956> call over WIFI has never, ever worked here, for some weird reason - always some BS "we couldn't connect with your WIFI"
[23:23:14] <Runaway1956> Something good happened today, with the cell phone

[21:08:11] <Bytram> FatPhil: Neat! Well done!
[20:57:09] <FatPhil> however, it seems there are no rounding niggles
[20:56:55] <FatPhil> the actual check is to re-square the (integer) root, and compare to the original, so it shouldn't matter, modulo rounding niggles.
[20:55:06] <Bytram> FatPhil: how does it affect the accuracy?
[20:53:58] <FatPhil> and a little xor-rather-than-swap takes it to 1.34!

[14:45:56] <cybiko123> And I thought 34 was bad enough

[14:22:06] <FatPhil> when my UPS blew up, it took my DEC Alpha with it. I've not had a UPS since. More trouble than they're worth
[14:18:37] <janrinok> yes, but a bit overkill for a raspberry pi. I would rather buy half a dozen spare Pi's and save myself a lot of money.

[13:16:07] <FatPhil> inz++ thanks for the ddrescue hint - I'd not used that before
[13:15:50] <FatPhil> OK, RasPi back up and running on the backup card.
[13:07:04] <FatPhil> some people just want to watch the world crumble.
[13:06:51] <FatPhil> you're a sadist for even thinking about such things
[13:04:57] <inz> but would the test rig survive nokia 3310?
[12:38:26] <FatPhil> I've seen a vid from ~2009 of the phone I have, the n900, in a nokia h/w testing lab where it's in a little room with two movable floors - the left lifts up 1m, and then jetisons the phone onto the right side. left drops, right raises, and jetisons the phone off to the left side. Repeat. Repeat 10000 times. And it still has to work afterwards. Can you imagine any phone from today passing that?
[12:35:43] <FatPhil> the commoditisation of tech, and the fashion-driven push to change everything yearly, has made component quality so poor nowadays.
[12:33:07] <inz> xD
[12:32:53] <FatPhil> oh, gawd, the backup card's got mmore errors than the actual card!
[12:32:32] <inz> I gpg-encrypt some of my data onto google drive, but only a small portion
[12:32:08] <inz> true
[12:32:01] <FatPhil> it's only smart if you actually do it!
[12:31:47] <inz> sounds smart
[12:31:47] <FatPhil> This has been a useful warning that we've not done that recently enough.
[12:31:35] <FatPhil> I try to back up home machines in the office, and office machines at home.
[12:31:29] <inz> (caveat: the server itself is not backed up, so don't trust it ultimately)
[12:31:02] <inz> if you don't have massive amounts of data, you can use the server for backup too, its also having a lot of unused disk
[12:30:57] <FatPhil> is there a way of working out what files were affected by the card failure?
[12:30:08] <FatPhil> I decided to not go to the sauna shop today, I'll wait and see how this "restore" operation works before deciding how urgently I need a new RasPi.
[12:29:22] <FatPhil> I do have an identical SD card I can restore it too, but that card contains the old backup of the broken card, so I'll make a backup of the backup before overwriting it.
[12:28:31] <FatPhil> some of the final report is confusing, it's saying ipos and opos only half the size of the drive, but the total amount copied seems to be the full size.
[12:26:34] <inz> yay
[12:22:31] <FatPhil> wowzers, ddrescue has mostly coped!
[11:57:50] <Bender> [SoylentNews] - Happy New Year, the PinePhone [and PinePhone Pro] Keyboard and Cases are Here! - https://sylnt.us - why-else-do-they-call-them-KEYboards?
[11:40:03] <inz> (I suppose it would run faster if it had a full core, not just a "thread", but these numbers are comparable)
[11:38:25] <inz> The sqrt() works for at least all x² where x < 2³⁷
[11:34:25] <inz> FatPhil, my tree now runs test in ~2.23s
[11:22:31] <FatPhil> However, I've found the email address of someone I used to discuss number theory with 15 years ago - maybe he can help...
[11:20:15] <FatPhil> O(n^2) is the tarpit, we'll never get past 32-bits
[11:19:19] <boru> Well, implementation native, not machine native.
[11:19:11] <boru> I think glibc has native types up to that.
[11:18:59] <boru> Going beyond 512b integers.
[11:18:33] <boru> Right, I was alluding to fast multiprecision integer arithmetic if that comprised some of your bottleneck.
[11:17:35] <inz> boru, the latest versions only use those +-* (plus some bitwise operations)
[11:16:39] <FatPhil> archie pu still going strong
[11:16:14] <FatPhil> it looks like the sci.math newsgroup contains about 99% loons now, I was thinking of asking there.
[11:16:09] <inz> It does seem that there are no false negatives in any near future either; tried with __uint128_t, and it just keeps churning along
[11:15:03] <FatPhil> simultanious quadratic dipohantine equations are not my speciality.
[11:14:47] <FatPhil> by that time, we might have a new algorithms completely rather than this brute force one.
[11:14:44] <boru> Out of interest, what primitive arithmetic operations do you need? If you don't need division, implementing fast multiprecision integer addition, subtraction and multiplication is fairly simple. With or without modular arithmetic.
[11:14:13] <inz> Yeah, the O(n²) is biting hard already
[11:13:57] <FatPhil> I suspect we'll never reach that far.
[11:13:00] <inz> All should be good 'till the ~3B where the rest of the program fails anyway
[11:12:12] <inz> And as you mentioned, there can not be false positives
[11:11:36] <inz> Did a test program that tested every square and it failed at 4294967297, as expected
[11:11:34] <FatPhil> I think here might be a corner case where the float gets rounded p above a square
[11:10:50] <inz> Was just about to write, that it indeed can handle all squares correctly
[11:10:28] <FatPhil> it might still work though, as long as sqrt is correct, we're comparing the square of the integer exactly still
[11:04:35] <inz> FatPhil, seems that using sqrt instead of sqrtl (for perfect square checking) would save some ~10% run time too, but as double only has 52(+1) bits precision, we're already past that point (the limit would be around 67M)
[10:34:25] <FatPhil> ddrescue started, I'll head to lunch now
[10:32:13] <boru> testdisk will try to read the broken parts, but if it's managed flash, the controller might just skip them or stall.
[10:29:49] <inz> It won't read the broken parts, but will not bail out on error
[10:29:23] <inz> FatPhil, you can also try (g)ddrescue to get an image
[10:27:23] <boru> But don't write to it or else you'll probably lose blocks of files.
[10:27:03] <boru> If you need stuff off it, try testdisk.
[10:26:47] <boru> Sounds like it's hosed, though.
[10:26:27] <boru> I thought that FS handled bad blocks.
[10:25:38] <FatPhil> yup, finally crapped out with dd: error reading /dev/mmcblk0: input/output error
[10:24:46] <FatPhil> OK, dd's cmopletely stalled now. I'll have to try an rsync instead, I guess.
[10:21:09] <FatPhil> I was breaking almost everything I touched yesterday too.
[10:20:33] <FatPhil> had a terrible night's sleep and I'm afraid to touch anything presently.
[10:20:14] <FatPhil> dd on the laptop is progressing, erm, non-linearly...
[10:19:50] <FatPhil> the PSU this is on has not given any problems in the past. Managed the 1200 day uptime on that board
[10:16:15] <boru> IMHO, get a NAS and NFS the important stuff.
[10:15:57] <boru> There you are, then.
[10:15:47] <FatPhil> the umportant partition was ext4, so journalled
[10:15:22] <boru> I think those cards are mostly NAND flash, as well.
[10:15:13] <FatPhil> herp derp, I was going to head to the office for a card reader to see what I can clone, and I've just realised I have one here on the lappy
[10:14:58] <boru> If so, that probably puts you in failure MTR range pretty quickly.
[10:14:47] <boru> Are you using a journalling FS?
[10:14:22] <FatPhil> I thik it was a cheap-arse card.
[10:14:11] <inz> I've had 2 SD cards die on me in an RPi

[09:20:01] <boru> e.g. fsck it.
[09:19:52] <boru> Does it support PXE or USB boot? If so, you could boot from RAM to investigate the source of the problem.
