This Is What Happens When Bitcoin Miners Take Over Your Town

Eastern Washington had cheap power and tons of space. Then the suitcases of cash started arriving.

EAST WENATCHEE, Washington—Hands on the wheel, eyes squinting against the winter sun, Lauren Miehe eases his Land Rover down the main drag and tells me how he used to spot promising sites to build a bitcoin mine, back in 2013, when he was a freshly arrived techie from Seattle and had just discovered this sleepy rural community.

T-Mobile Interference Caused by Man's Bitcoin Mining Rig

T-Mobile customers in northern Brooklyn had been complaining for much of last year about mysterious service issues that consistently plagued certain areas of the New York City borough. After a lengthy investigation, the FCC and T-Mobile discovered the culprit was that one man's bitcoing mining rig (more specifically a Bitmain Antminer S5) was somehow causing the interference in the 700Mhz band. "The device was generating spurious emissions on frequencies assigned to T-Mobile’s broadband network and causing harmful interference," the FCC's enforcement bureau told the man in the letter.

SEC halts trading of three companies promoting crypto sales
The Securities and Exchange Commission (SEC) on Friday suspended trading for shares of three companies that promoted plans to sell their own cryptocurrency.

The SEC banned investors from trading shares of Cherubim Interests Inc., PDX Partners Inc., and Victura Construction Group Inc., until March 2 as it investigates the companies.

All three companies announced in January that they had acquired high-quality blockchain technology, the ledger system through which cryptocurrencies operate. The companies said they would also launch an “initial coin offering” (ICO), in which a corporation sells units of a proprietary cryptocurrency as it would sell shares on the stock market.

The SEC cited “questions regarding the nature of the companies’ business operations and the value of their assets,” as the reason for its action. It’s the latest measure taken by the agency against companies aiming to rake in cash off of cryptocurrency’s rise.

Vendors on Amazon now selling 6-packs of GPUs for cryptocurrency mining
(You will need to disable any ad-blocking options/add-ons you might have in your web browser to view the article)

The demand on GPUs created by cryptocurrency mining has resulted in exorbitantly high priced graphics cards that now routinely sell way above MSRP. If you're willing to cough up the cash, though, you can find just about any card out there. You can even buy in bulk, as third-party vendors on Amazon look to hawk multiple graphics cards at once. Just don't expect a price break.

... To be clear, we're not recommending that anyone actually buy any of this stuff. Not that our recommendation is needed—over at Newegg, similar overpriced bundles are apparently attracting customers in droves, with several listings showing as being sold out.

Mathematicians Awarded $3 Million for Cracking Century-Old Problem

NOTE: Best to turn on your Ad-Blocker before clicking the above article link. Space_com tends to have very intrusive & annoying ads.

Two mathematicians have each earned the (massive but countable) sum of $3 million for a proof that could one day help scientists understand extra dimensions.

Christopher Hacon, a mathematician at the University of Utah, and James McKernan, a physicist at the University of California at San Diego, won this year's Breakthrough Prize in Mathematics for proving a long-standing conjecture about how many types of solutions a polynomial equation can have.

...
Window into extra dimensions
Right now, Hacon andMcKernan's proof has absolutely no practical application. But ultimately, it could provide a theoretical window into extra dimensions, Hacon said.

Try PSP instead. They're about the same size tasks right now. If PSP works and SoB doesn't, it might have something to do with running LLR in PRP mode.


Might be something with the llrSOB way of doing things.

The 2 SGS tasks completed & validated with no issues.

Currently have a pspLLR task running on that PC now for about 35 minutes with no problems. ETA to complete is 26 1/3 days.

Still getting SOB tasks CRASH on this PC even after a cold restart / reboot, Chkdsk/ScandDisk & project RESET to get clean PrimeGrid files.

Started, completed & validated a SGS task after project reset with no problem.


Could there be a possibility of something in the llrSOB EXE that is NOT COMPATIBLE with Windows Vista x64?

Below is the Windows System Error logging when the task crashed:
Faulting application primegrid_cllr.exe, version 0.0.0.0, time stamp 0x58af1be2, faulting module primegrid_cllr.exe, version 0.0.0.0, time stamp 0x58af1be2, exception code 0xc0000005, fault offset 0x0000000000061950,

Happened again. Another crash.

CPU time 3.57. Run time is high because I was not at the computer when it crashed.

https://www.primegrid.com/result.php?resultid=798119876

Have temporarily stopped requesting work from PrimeGrid on this PC. As noted previously, no other projects are having problems retrieving or send back work.


This time it DID leave a "trail" in Windows Error reporting.

Date/Time of log entry 2017/04/11 @ 1823 (This is Local Time = UTC -5 Hrs)

Faulting application primegrid_cllr.exe, version 0.0.0.0, time stamp 0x58af1be2, faulting module primegrid_cllr.exe, version 0.0.0.0, time stamp 0x58af1be2, exception code 0xc0000005, fault offset 0x0000000000061950,

Below is the logging from BOINC to retrieve the task.
Strange thing that stuck out to me is BOINC sent a message to the CERN/LHC project servers NOT PrimeGrid???
