Thanks Graham.  My main issue is getting a URL that returns the JSON text for the blocks.  Parsing after that is easy with various methods, but I'm not sure what the right URL is.

The node API is on 127.0.0.1:<RPCPORT> where <RPCPORT> defaults to 31397.

I dumped the postgresql database: https://minkiz.co/library/gapblocks.sql.gz

I crudely interpret the following as “nothing to report of late” ...

gapblocks=# select distinct(merit) as merits, gaplen, height from blocks where gaplen > 20000 order by merit desc limit 20;
   merits    | gaplen | height |
-------------+--------+--------+

Is this what it is doing to increase the difficulty with no return on price.

The instance is not mining, it's sole activity is to respond to getblock API calls made by a bit of Python intended as a response to:

I'm looking for some simple code (e.g. Python, Go, C, Perl, Java, etc.) to scrape blocks to JSON / text.

This coin is old coin and dead coin. They seem to have disappeared, they have been missing long enough for us to see that.

FUD, bitcointalk's own familiar brand of “fake news”, now mechanically produced by algorithm-driven account farming. Reporting it always was verging on the futile, now it's pretty much totally pointless.

There is any slack or telegram for this coin,for talk to the devs ?

Dunno what you have in mind but you'd best trot it out right here, where everyone can see.

Kinda useful - Mervin Seiberlich has created a jupyter notebook that basically lays out the details of the procedure for signing, checking and storing RDF graphs. The source is:

https://github.com/LibrEars/Linked-data-for-scientists-with-python

and there's a rendered version on: https://nbviewer.jupyter.org/github/LibrEars/Linked-data-for-scientists-with-python/blob/master/Linked%20data%20for%20scientists%20with%20python%20-%20Part%201.ipynb (or use the link in the README displayed on the Github repos).

It's as near a road map as I'm likely to produce.

Cheers

Graham - how we can control supply now? I know only one way - take money supply from coinsmarket --- SLM burned coins = real supply.

Thank you for that informed analysis, especially the stackexchange link, I shall be following that up.

doesn't bode well

I half suspected as much. I'm old enough to remember Arnold Arnold (I can only find this one reference https://www.amazon.co.uk/Geometric-Solution-Fermats-Last-Theorem/dp/B001OR8FJQ) from the PR ruckus of the time.

Yeah, read upthread post : https://bitcointalk.org/index.php?topic=1080289.msg21247843#msg21247843 and, given that the basic nature of the question testifies to your innocence of the content of this thread, I strongly recommend you read all 7(!) pages.

make[1]: Nothing to be done for 'libleveldb.a'.
make[1]: *** No rule to make target 'libmemenv.a'.  Stop.

I'v experienced this on more than one occasion. Sometimes it can be trivially solved by running make libmemenv.a in src/leveldb and sometimes not. If not then the only recourse is to try and deduce a fix by cross-referencing against the contents of leveldb and the top-level (qmake/autotools) build file of a close clonecousin.

FWIW: I won't be responding to any more “Can you help me?” PMs.

This exercise is public for a reason, so that knowledge is distributed - and from my perspective, so that others besides me can take turns in passing it on.

Some people are mentioning, that they would like to have a pool. I've seen there is a code to compile pool, someone test it, that it works?

I tried to get https://github.com/kryptoslab/node-open-mining-portal up and running and couldn't build node-multi-hashing (one of nomp's dependencies) on any version of node other than  0.10. so, I doubt if it can be used in production.

I got a bit further using a contemporary-to-nodejs-0.10 linux distro

A bit of furkling around on Github reveals a recent version of node-multi-hashing which installs successfully under node v8.9.1: https://github.com/Kukunin/node-multi-hashing.git

Unfortunately, that won't rescue node-open-mining-portal but the dcrypt implementation could be plugged into node-pool: https://github.com/bonesoul/node-pool.git, following the model for scrypt as implemented here:

https://github.com/bonesoul/node-pool/blob/develop/src/algorithms/algorithms.js#L21

It's maybe a route to a working pool for Slimcoin, if anyone wants to explore in that direction. node-pool compiles and executes under node v8.9.1. I haven't managed to connect it to testnet yet but it's looking promising.

Interesting item posted to Hacker News, a paper published at October's Fields Medal Symposium in Toronto: A Schr¨odinger Equation for Solving the Riemann Hypothesis (PDF). The approach is mentioned in the wikipedia entry:

Quote
The calculations in Odlyzko (1987) show that the zeros of the zeta function behave very much like the eigenvalues of a random Hermitian matrix, suggesting that they are the eigenvalues of some self-adjoint operator, which would imply the Riemann hypothesis. However all attempts to find such an operator have failed.

is there any new things going on here?

Loved the coin, but seems to need a boost or it will be the next coin to be delisted on the exchanges.

What's left of the developers and the roadmap?

CLAM this is going to die, developers should release the details of the current currency or do something practical, it is really urgent!

Clam is being pulled from Polos margins. What’s the deal?

If any of the above posts were not merely account farming - you're gong to have to raise your game to get an answer these days. Try including some support for your otherwise baseless assertions/assumptions,

I got a bit further using a contemporary-to-nodejs-0.10 linux distro (Ubuntu 15.10 uses nodejs 0.10.29), and specifying an appropriate “0.10.0” version limitation for bignum (instead of the dubious “*”) and managed to run npm update successfully in all three node-* repos  (the bignum code incorrectly thinks the executable is called node (instead of the correct nodejs) when it tries to load nan - which I discovered by cloning the node-bignum repos and trying to npm install from that).

However, trying to start the pool resulted in a raft of error statements, so I ended my exploration at that point.

There are two shell script files that need to be executable in order for the compilation process to succeed. If the dev has omitted to make them executable, the above error is seen:

share/genbuild.sh and src/leveldb/build_detect_platform

Make them both executable and try again.
