[01:08:29] <Tekk> To submit a story is it just =sub (url)
[01:08:38] <Tekk> Or is that because people are known?

[01:20:53] <Tekk> FatPhil, I have to be able to get to the site to find the news post first either way :D
[01:38:19] <Bytram> Tekk: (1) You can submit the story directly on our site at ( https://soylentnews.org ) but it is a big plus if you know basic HTML.
[01:38:23] <systemd> ^ 03SoylentNews Submissions
[01:39:21] <Bytram> (2) As for bots, "=submit URL" seems to work the best most often.
[01:40:50] <Bytram> Example: =submit https://www.sciencedaily.com
[01:40:50] <systemd> ^ 03New copper surface eliminates bacteria in just two minutes, scientists report
[01:48:39] <Tekk> Probably better to submit it on the site, thinking about it.
[01:48:58] <Tekk> Add the context that it's the first release in I think 5 or 6 years now, what's been added, etc.
[02:07:23] <Bytram> nod nod. Use stories you've seen here as a guide. Use an ellipsis "[...]" to show where text has been omitted. Use <b> ... </p> to set off bold text and <i> ... </i> for italics, and so on. We want to help, so feel free to ask questions here, too!

[02:37:07] <Tekk> Oh. I was saying I get html. I've maintained a web page on and off for a long time.
[02:42:19] <Bytram> Kewel!
[02:42:38] <Bytram> I look forward to your submission!
[02:46:15] <Bytram> The submission page ( https://soylentnews.org ) conveniently has a link to the submission guidelines page ( https://soylentnews.org ) which you might find handy to look over in advance. (hint hint =)

[06:47:36] <SoyCow7385> I see them how you see me, you hear them talk and wonder, "are they retarded?"
[06:48:41] <SoyCow7385> Mexican hate is well-deserved, even the worst Blacks are capable of behaving when you wanna talk to them.

[11:39:59] <FatPhil> Anyone got a spare core they can run some mathematical (Pari/GP) code on for me? My little low power celerons are starting to creak a bit.

[12:19:36] <FatPhil> I'm rocking honking great "Intel(R) Celeron(R) 3205U @ 1.50GHz"s :)
[12:19:47] <boru> No, I meant what you have to run.
[12:20:09] <boru> And how many cores do you need?
[12:20:40] <FatPhil> a 3 line pari-gp script, that's all
[12:20:59] <boru> What do I need to install to run it?
[12:21:10] <boru> Just pari?
[12:21:41] <janrinok> FatPhil, I've got several computers doing nothing at the moment. What software do you need. What is pari?
[12:22:12] <FatPhil> On debian-alikes the interpreter package is called "pari-gp"
[12:22:32] <boru> Probably just pari on BSD, then.
[12:22:35] <boru> Send it.
[12:23:13] <FatPhil> I'll write a little webpage with copy-pastable stuff...
[12:23:29] <boru> Just use sprunge or some paste site?
[12:24:25] <janrinok> I'm just installing the software now
[12:25:09] <boru> janrinok seems really excited to do this, so let him.
[12:25:28] <janrinok> not fussed either way
[12:25:49] <janrinok> I don't even know what I've taken on...

[12:36:36] <systemd> ^ 03Simultaniously Square Sums of Mostly Squares
[12:38:06] <janrinok> OK but how do I run that?
[12:39:49] <FatPhil> start pari so you get a prompt
[12:40:22] <FatPhil> probably the command is 'gp'
[12:40:37] <FatPhil> pari's the library, gp's the interpreter sitting on top of it
[12:40:43] <janrinok> k
[12:40:53] <FatPhil> enter ``#''
[12:41:03] <FatPhil> ? #
[12:41:03] <FatPhil> timer = 1 (on)
[12:42:05] <FatPhil> enter the f2=... line, and it should print a matrix as the result.
[12:42:16] <janrinok> yep - and just paste in the script?
[12:42:54] <FatPhil> yup, I've set up the for loop to only scan a small range, for timing purposes
[12:43:49] <janrinok> there is something it doesn't like - I'm just trying to find out what...
[12:44:56] <FatPhil> might be literal tab characters
[12:45:21] <janrinok> Pasting the f2 line is a none starter - what about the single one-line command?
[12:46:43] <FatPhil> I've removed the tabs now, but yup, the one-liner is identical apart from the bounds in the loop (it's the range I'm searching now)
[12:49:33] <janrinok> syntax error unexpected Send: ,,,+c*c),print)a" "b" "c)))))
[12:49:52] <janrinok> indicates too many too few ')' at end of line
[12:50:18] <janrinok> gp shows as sleeping, no CPU work at all
[12:51:59] <FatPhil> I just copied the one-liner (with the 1,5000 bounds, and my gp interpreter's fine with it
[12:52:23] <FatPhil> 19 results in time = 13,981 ms.
[12:55:01] <janrinok> *** at top-level blah blah blah. I'm running it on another machine and it isn't easy to cut and paste to this one
[12:56:26] <FatPhil> I've put a 1-line version of the f2= line for copy-paste too now
[12:57:01] <janrinok> *** at top-level: ...%8;for(b=1,a,b8=b%8;f3=f2[1+a8,1+b8];if(f3,a2b
[12:57:01] <janrinok> *** ^---------------------
[12:57:01] <janrinok> *** incorrect type in _[_,_] OCcompo2 [not a matrix] (t_POL).
[12:57:01] <janrinok> *** Break loop: type 'break' to go back to GP prompt
[12:59:09] <janrinok> its running now
[12:59:25] <janrinok> time = 5.499 ms
[12:59:50] <FatPhil> nice! way over twice my speed
[13:00:06] <janrinok> that is using a single core - is there an option for mulitple cores?
[13:00:18] <FatPhil> you did get 19 lines of results, starting 4 4 4?
[13:00:24] <janrinok> yep
[13:00:42] <janrinok> last line 4900 4900 4900
[13:02:00] <FatPhil> Excellent, everything works. If you can change the loop bounds from 1,5000 to 150000,200000 then that should be work for the rest of the day. (I plan to put this little diversion to bed by then)
[13:02:28] <FatPhil> arrow keys should let you edit the command
[13:02:46] <janrinok> I'm just transferring it to a 4 core spare machine that I can leave running for days if you want.
[13:04:17] <FatPhil> this is an "embarassingly parallel" task, you can start multiple paris and give them different bounds (time scales with O(n^2) though)
[13:06:30] <FatPhil> I'll fling the problem description at some proper mathmos later today, and they might come up with some real insights which might make this not-entirely-brute-force search redundant, but there's no harm in just ramping up the ranges.
[13:08:54] <janrinok> well, I think it is running on a remote machine now. Certainly the CPU is earning its keep today.
[13:09:14] <janrinok> not much to see in the terminal window though
[13:10:48] <FatPhil> I found nothing in the range 100000,150000 so the results are really thinning out :(
[13:12:06] <FatPhil> the biggest 'interesting' result is that 1550^2+6179^2+70835, 1550^2+6179+70835^2, and 1550+6179^2+70835^2 are all square.
[13:12:48] <janrinok> I'll take your word for it
[13:14:53] <janrinok> As sit is not exactly a spectator sport, I'll leave it running and we will see where we get to. If you want an update at any time just yell on here.
[13:16:29] <FatPhil> Alas it doesn't print its progress, it's either running, finished, or crashed1
[13:20:56] <janrinok> One line printed 4488 4488 152593 - so it is running
[13:29:04] <janrinok> 34007 1255311 155311
[13:29:37] <janrinok> I don't know if that gives you any sense of the speed on the new machine?
[13:31:34] <FatPhil> you're 2-3 times faster than me, that might complete by evening.
[13:33:33] <janrinok> and if not, it will be ready for tomorrow morning
[13:37:34] <FatPhil> More explanation: http://fatphil.org
[13:37:34] <systemd> ^ 03Simultaniously Square Sums of Mostly Squares
[13:39:47] <janrinok> if you have more of these to do tomorrow I can set up a machine that can do 3 jobs in parallel - either smaller individual bounds or 3 different bound ranges.
[13:42:39] <janrinok> Bytram should be appearing soon clutching his first cup of coffee of the day
[13:44:53] <Bytram> I was just trying to debug a program, heard hexchat go beep, and lost my train of thought... yes I need coffee!

[18:53:34] <janrinok> do you want me to set another run going?
[19:41:18] <FatPhil> wowsers, nice work.
[19:42:29] <FatPhil> I did 200000-250000 during the afternoon/evening, and I reckon you could slay 250000-400000 overnight.
[19:42:59] <janrinok> I can give it a try
[19:43:49] <FatPhil> I've worked out the maths of another subset of the solutions now. it's just the classic x^2+y^2=z^w-1 problem under a different guise.
[19:45:25] <janrinok> OK, that's running on a slightly slower computer (but not much) - I don't want to have to listen to it all night!
[19:46:11] <FatPhil> alas, my crappy micro-PC is in my bedroom, so I can't run overnight with the fan all spun up.
[19:47:09] <janrinok> Well my really powerful one is also in my bedroom - in fact there are two of them. Same problem with overnight running. The one I am using for tonight is in the cellar.
[19:49:35] <janrinok> but I'm calling it a day for now. Speak to you tomorrow.

[21:44:36] <FatPhil> inz: wowzers - lovely, thank you! doing 400000-600000 on one core, and 600000-800000 on another!
[21:45:21] <FatPhil> This reminds me of the days of yore...
[21:47:12] <FatPhil> I only thought I'd get to about 10000 in a day with my prior version of the code (getting to 5000 took an hour, and it was O(n^3)).
[21:48:15] <FatPhil> bit too tipsy to update the website with the progress, but I've recorded all jan's results for processing later.
[21:49:10] <FatPhil> Unfortunately, when I went to a brewpub (not ours) earlier, the head brewer was there. And we chatted ... about beers ... that were on tap ... and demanded resampling...
[21:51:16] <FatPhil> oooh - 166464 166464 166464 - that's a Pell's Equation solution
[21:51:45] <FatPhil> as expected. But the a=b=c will be in the minority
[21:51:55] <FatPhil> and they grow at an exponential rate
