Now, you want me to have no peace over the weekend, huh? :razz:
Congrats.
Unfortunately my rigs are down for a while, under maintenance, and trying to save money (Australia is sucking all my funds now, the Uni for the little miss is costing me over $50k per year...), but I still can fire up few 580s and two Titans that I bought from airsquirrels not long ago...

My 2017 project ended 3 months early
 
25,000 LifeTime GhzDays in PM1 -- check
25,000 LifeTime GhzDays in ECM Small -- Check
25,000 LifeTime GhzDays in ECM Fermat -- Check
1,000 ECM Curves (at the current B1/B2 level) for every unfactored exponent under 20,000 -- Check
3 - 5 new ECM Factors -- Almost. I found 2; got teased with 2 finds in the first half of the year but none since. Mind you, these were the ONLY 2 newly factored sub-20,000 exponents in 2017 for all of GIMPS.

I have also run a lot of curves on several exponents below 10K, but to no avail. No wonder, it´s a really tough mission, and my processing resources are rather scarce at the moment.
I´m currently engaged in a different task: trying to find, through ECM, first factors for exponents still at 63 bits of Trial Factoring. There are currently 712 to choose from.
I hope to find 1 or 2 before the end of the year.

And of course I occasionaly run some curves on M1277, using GMP-ECM for Stage 2...

By the way I also did the following curves for Fermat Numbers:

[CODE]4096 1000
8192 1000
16384 1000
32768 1000
65536 500
131072 500
262144 500
524288 232
[/CODE]
Why 232? Because that is how many I needed along with all the above to get to 25,000 GhzDays Lifetime in ECM Fermat.

And as you might have guess I found ZERO new factors

I might have more luck an average...
A few days ago an "Explosion" happened on the INEOS production site in the BAYER Chempark in Dormagen. About 14 people were hurt due to the sound wave.

I just arrived my car at the moment of the explosion. It was so f***ing loud.
Some kind of safety equipment, a rupture disc, broke and highly flammable Ethelyn ignited.

I am glad you weren't any closer.

I still get the heebie-jeebies just thinking about the [URL="https://en.wikipedia.org/wiki/West_Fertilizer_Company_explosion"]ammonium nitrate fertilizer explosion in West, Texas, USA.[/URL] People watching from a mile away were deafened when it went off.

Recently I found the USB stick with the stage1 savefiles of the M1277 curves (with B1=2.9e9) I ran in 2016 on an offline machine. I checked the SIMGAs and they're different from the ones I completed in the beginning of the year. I've now queued them for B2=82e12 with GMP-ECM, so in a couple of weeks those should be ready. In total it should be the equivalent of a couple of 1000s 'Primenet 800M curves' :smile:.

Fast forward to the aftermath of Hurricane Harvey: when the Arkema chemical plant in Crosby started producing large, smoky Roman candles, first responders were hospitalized, victims at least in part of poor planning. Of course, the lack of information about what was at that plant and how it was stored, had nothing at all to do with this. And, when it comes to the possible effects of the smoke from those "reactions," ignorance is bliss
:devil:

Yes. The response to the West disaster was pure Texas BS. "We can't have people's silly worries interfere with Business."

So same on the PEPCON Explosion. No one know how many product was stored on the site.
Hot work (welding) caused (opened!) storage drums with product to burn. The responders were hitten by a shockwave from the 1. large explosion. They had no information on the products from PEPCON.

My third e-book has been published :smile:

It's a collection of Fredrik Brown-style SF short stories with a consistent base of logic and math. Too bad it's in Italian (at the moment).
