jc blog - tales of a modern-day nomadic hunter-gatherer

Follow jcomeau_ictx on Twitter This is the weblog of Intrepid Wanderer. You never know what you might find here; graphic descriptions of bodily functions, computer programming secrets, proselytizing for the antichrist, miscellaneous ranting and kvetching, valuable information on living off the land... if you don't share my rather weird interests you may want to try slashdot instead.

You can consider my Del.icio.us links an extension to my blog, as are my LifeTango goals and my other to-do items. My to-buy list is also public, but only for sharing any useful ideas that might be there; I'm not requesting charity, neither do I offer it.

You can find me easily in google searches, as jcomeau, jcomeau_ictx, or jcomeauictx. There are lots of other jcomeaus, but AFAIK I'm the only jcomeau_ictx out there so far.

If you want to comment on anything you see here, try the new Facebook comments, reachable by clicking the "[comment]" link at the end of each post. If for some reason that isn't working, go ahead and email me, jc.unternet.net. You know what to do with the first dot. Make the 'subject' line something reasonably intelligent-looking or it goes plunk! into the spambasket unread.

went to INAMI this morning and they told me to come back Friday, they still didn't have my card. I guess they're waiting for the Mexican post office to come through. my chances of getting it this year are getting pretty slim. [comment]


just mined my first block of AmericanCoin in years:

took what, a day and a half? at a hashrate of about 3kH/s between all 3 machines I had my script running on. [comment]


so once you have a litecoin-based crypto daemon running, you can copy its config file to your other machines for mining using SSH tunneling, e.g. for AmericanCoin: $ ssh -L9057:localhost:9057 amcserver, and run your getwork-based mining script against it as if it were running locally. [comment]


had to revert the changes to the "dust" calculation. the transaction I made was sent with no fee, all right, but it was never accepted. here's the tail end of americancoind listtransactions:

although I haven't dug into the code enough to really understand it, I'm guessing it's getting rejected at the relays for not having the penalty fee. I suspected it would happen, but it was worth the test. [comment]


finally got my modified AmericanCoin sources to build against my older Boost libs by installing g++-4.8 and using $ make CXX=g++-4.8 BOOST_INCLUDE_PATH=~/include BOOST_LIB_PATH=~/lib -f makefile.unix.

now to see if it'll actually run... [comment]


AmericanCoin again... some recent activity on Bitcoin Talk, including this pointer to a graph showing AMC rising quickly, roughly equivalent to BTC's rise.

but that could just be wishful thinking, based on the last known AMC/Satoshi ratio. [comment]


couldn't see spending 20 pesos on 33 grams of black pepper at the grocery store, so today I tried the seed store, Semillas Guadalajara, behind the Mercado Madero. only $200 pesos per kilo as compared to $600, so I got 100 grams for that same 20 pesos.

also, at Mercado Bravo, I scored a liter of crude lard, manteca, for 25 pesos, compared to 90 pesos per liter for my preferred brand, Porky, at supermarkets. I don't know about the quality yet, though. [comment]


so AmericanCoin isn't really dead after all. it's just that something in my config prevented the daemon from locating active nodes. I started up a newly compiled daemon on my test server and it found a bunch of nodes immediately; I added the hostnames to my local config with addnode= and my blockchain is caught up. I sent .001 coin to my other server, though, and a (presumably penalty for dust) transfer fee of .005 was taken out. ouch. don't want to make that mistake with Bitcoin. [comment]


last night I made another attempt at compiling the dogecoin sources on a "spare" server, something I've been making lame attacks on for 10 months now. looks like it finally built.

going back through my history log, here are some of the things that made the difference. first problem was that the header libdb_cxx.h wasn't found. I had to recompile the BDB 5.1 sources again:

$ cd ../db-5.1.29/build_unix
$ ../dist/configure --prefix=/usr/local --enable-cxx
$ make
$ make install

then I was missing most of the boost libraries. sudo apt-get install libboost-all-dev libminiupnpc-dev fixed that and another potential problem. then back to /usr/src/dogecoin:

$ ./configure --without-gui
$ make

it was taking forever. stopped the job with ^Z and looked around. top showed I was thrashing, so I shut down bitcoind to free up some memory. then resumed compiling, it still thrashed now and then but at least it was building. then in the final linking of the binary, it crapped out with two errors relating to boost::program_options, the first was with to_internal and I forget the other one. I looked in the sources, /usr/include/boost/program_options/detail/config_file.hpp, and it looked like it should have been there, because BOOST_NO_STD_WSTRING was not defined. googled around and got some StackOverflow results, most of which said to downgrade boost, and one which said to upgrade g++. I chose the latter, and left it running all night with make V=1 for verbosity. it worked. [comment]


yep, coinmarketcap.com shows Americancoin is dead. oh well. it was all a gamble anyway. [comment]


so it turns out I apparently don't need to download any more blocks in order to send my balances to another address. must have known that at some point and forgotten. that's good to know in case I need to cash out. [comment]


bitcoin (BTC) balance 0.05486945, assuming it's still there... don't have room to download the blocks. worth USD687.20 according to coinmarketcap.com at USD12524.30 per bitcoin. [comment]


Argentum balance: 330.039, a little over a penny each so worth about USD3.30. [comment]


americancoin balance is 17434.574, but I'm afraid that one may be dead. it's not listed at coinmarketcap.com. [comment]


going through my account balances, those I can currently access. my dogecoin holdings are 23293.957, worth about USD58 according to coinmarketcap.com. [comment]


so Rappo didn't drop the ball this time, but PdfFiller didn't send on the W9 as it was supposed to, so he didn't transfer the funds. but he did follow up by email, I sent copies, and the funds made it through. after Bountysource and Paypal both got their cut, it's down from $750 to $655.12, but still that's a pretty good return on investment for the few hours it took to solve the problem and follow up. [comment]


went for a long jog/walk today, out to Soriana and back. jogged for the first half hour and got to the corner of Farías and Colosio. left at 12:53 and got back at 4:07.

my "garden" in the arroyo north of Home Depot is a wasteland this year. still lots of native amaranth, but no tomatoes, squashes, or mint. lots of cockleburs where there wasn't before.

found real butter at Soriana, their own brand, MXN13.90 for a 90g stick, which works out to about USD3.75 per pound. not bad at all, and their breads are as low as 1.6 pesos for a whole wheat roll, under 9 cents. for those prices I could live on just bread and butter for a while, without even having to cook. too bad the nearest Soriana is about 3 miles away, where Mega used to be. [comment]


finally I was able to push that piece of hanging tooth enough so it broke free of the gum. no more pain. celebrated with a 2/3 pound hamburger on homemade whole-wheat bun, and of course the obligatory Ballena de Pacifico Clara. [comment]


a few days ago one of my cracked teeth finally split, and one piece is pulling against the gum whenever I bite. painful. [comment]
