@d5000

OP looks quite better now with logo!!!

As it says that total burnt SLM are 190000+, is there information how many totally SLM are decayed burnt?

Pity, that no one is interested in the bounties, or shall be reviewed what has been done from the list and start distribution. As well i think it should be checked if all donors of SLM are still interested to give SLM. I am one of them and my position is the same.

If my model of Slimcoin's burn algorithm (and associated data structures) is right, then it would be the result of the "burn address balance" minus "Formatted nEffectiveBurnCoins" (one of the values you get if you type in "getburndata"). In this case, about 800.000 SLM "decayed" from 2014 to today.

Pity, that no one is interested in the bounties, or shall be reviewed what has been done from the list and start distribution. As well i think it should be checked if all donors of SLM are still interested to give SLM. I am one of them and my position is the same.

I also just today thought about updating the whole "bounty" part as it's pretty old ... Thank you for the confirmation of your bounty.

For the other users that have announced a bounty, I'll left this question here for a week or so and then PM the users if they have a Bitcointalk or Reddit account:

To all users: Do you have announced a bounty in 2016 or early 2017 that is mentioned in the OP?
Please confirm it replying to this thread. Thank you again!

Some of the bugs have probably already been solved (or were related to the old Peercoin version of SLM 0.3.2). But things like an Electrum port or a working pool are obviously still very much desired features.

When will be Polo exchange?

When will be Polo exchange?

Polo doesn't seem possible anytime soon. Bittrex is more realistic in case we have 3 BTC entry fee. But it's a huge amount of money considering current Slim price. 3 BTC could buy 300 000 Slim which is like 2% of the total supply.

So I've left my wallet open and my computer on, and set the reserve to 0, when do I get staking rewards? Not sure how it works....

So I've left my wallet open and my computer on, and set the reserve to 0, when do I get staking rewards? Not sure how it works....

Here we have a guide:

http://slimco.in/proof-of-stake-guide/

Staking begins if you don't move your coins for 7 days, and then your probability to find blocks increases until day 90 after the last transaction.

Techniques for emotion detection and content delivery

Abstract
Techniques for emotion detection and content delivery are described. In one embodiment, for example, an emotion detection component may identify at least one type of emotion associated with at least one detected emotion characteristic. A storage component may store the identified emotion type. An application programming interface (API) component may receive a request from one or more applications for emotion type and, in response to the request, return the identified emotion type. The one or more applications may identify content for display based upon the identified emotion type. The identification of content for display by the one or more applications based upon the identified emotion type may include searching among a plurality of content items, each content item being associated with one or more emotion type. Other embodiments are described and claimed.

Unfortunately for USians, the functioning of the econo-political system in the US has degraded to the extent where this ^^^^ nonsense is more likely to be approved than not. Happily we can let FB continue pursuing its own corporate death spiral by poisoning its own watering hole and then having to introduce increasingly preposterous remediation strategies to (unsuccessfully) neutralise the poison that it introduced in the first place.

I call this sort of thing, AI. Yes, that's basically the same “AI” as you're seeing plastered all over the media and prompting discussions of the ethics of classification algorithms applied to machine-logged “records” of human behaviour, etc. the sort of AI where the semantics of the abbreviation more properly refer to “Autistic Intelligence”.

I will readily concede that in significantly-reduced bandwidth channels, it is now effectively impossible to distinguish machine-hosted autistic intelligence from human-hosted autistic intelligence.

I've yet to get a sense of whether that's going to be a Good Thing(tm) or not.

Compiled fresh on Armbian (which uses ubuntu 16.04 packages) with Berkeley db 4.8.

Thoughts? Suggestions?

[cryptovore]

for whatever reason, this version

Code:

"version" : "SLMv0.5.0-15-g3092f1e-dirty-alpha"

works, now downloading the blockchain. Will report later if it crashes, but so far so good. I think it's the feature.bip65 branch.

[cryptovore]

The plot thickens...

After I successfully compiled and started the 0.5.0 version mentioned, it still continued to crash randomly, while downloading the blockchain, without any info. I feared a hardware problem, and a look at the Armbian logs showed that the SD card, via the eMMC driver, was doing way too many writing/reading cycles and choked.

The solution was to move the blockchain files to an USB drive and start the Slimcoind daemon with a different datadir option

Code:

/usr/local/bin/slimcoind --datadir=/media/usb/.slimcoin

But even now I was experiencing random crashes, due probably to a certain limitation in the file descriptors on Armbian / Odroid XU4. So I ended up creating a watchdog for the Slimcoin process, called monitorSlimcoin, which is in turn started by a different file, called startSlimcoin.

startSlimcoin file, saved in /usr/local/bin/startSlimcoin

Code:

/usr/local/bin/slimcoind --datadir=/media/usb/.slimcoin

monitorSlimcoin file, saved in /usr/local/bin/monitorSlimcoin (and caressed with a gentle chmod a+x before launching it)

Code:

#!/bin/sh

until slimcoindDaemon; do
    echo "Slimcoin daemon crashed with exit code $?.  Respawning.." >&2
    sleep 10
done

to be sure it will survive reboots, I added this line on crontab, by firing up crontab -e

Code:

@reboot /usr/local/bin/monitorSlimcoin

The natural progression would be to add the mining option directly to the slimcoin.conf file, but atm I don't know if it's generate=4 (the number of cores) or setgenerate=4, and I'm a bit tired. Will do more trials (and, obviously, errors) tomorrow, and report back.

I know this setup is almost unbearably ugly, but it does the job. And the job is to assess how reliable such a device would be for a general purpose Slimcoin node. For those of you not aware, Odroid XU4 has an octa-core ARM at 1.6Ghz, and 2GB RAM, almost like an entry-level laptop, but it only draws 5-10W of power.

[muf18]

Yeah I know what Odroid is. It basically has the same components as tablet or phone like Galaxy Alpha.
Interesting this is.
But isn't some efficent x86 cpu better and more reliable for a node? Like Atom clover trail or newer? That is more powerful than arm and on the same power consumption.
You can habe there a full or lite/cut off version of Windows X86 or Linux, which should be more reliable i think.
But it would be cool idea if it would work on eg. Ubuntu Touch - I would even buy some phone Ubuntu Touch compatible with sideload/dual boot and test it through.

About translation once again - I asked my friend he told me that he knows some people who know French and Italian really well, but they want some money - would slim community wanted to do something like this? I'm not against it, tho I won't ask you for money, because it's against our idea I think. So I told him no, but I should first ask you.
There are some nodes in France and Italy - would this guys could reply at least here to see if there are here or just mining without being much into the further growth, of the coin (it's not bad - it's ok for me, just asking if someone would like to make this), if I could I would make it. I will probably start to learn more languages this year, so maybe I can translated like in 2018, maybe a little earlier.

Interesting enough we were mentioned here:

Shouldn't be so difficult to port it or should be?

BTW. - can anybody tell me how is this possible - number of nodes are at the stable rate or decreasing, but instead hashpower is increasing? Wtf? I mean you have to have full node, to do mining as far as I'm concerned, because there aren't any pools for now, and GPU miner at least for me wasn't working properly? So, how is this even possible? Somebody has created a new gpu miner or have that one worked correctly?

You only need one node to mine with many CPUs, even without pool.
I don't mine PoW on SLM anymore, but I had 5x 4-core CPUs mining against one node. I used one of the cpuminers on the OP but I can't exactly remember which.

[ArchitektoR]

To all users: Do you have announced a bounty in 2016 or early 2017 that is mentioned in the OP?
Please confirm it replying to this thread. Thank you again!

Yes and I can even add more in BTC if we have some progress on getting to exchanges. Asked some times gjhiggins about his SLM address to send some donation/bounties - because his work for the wallet is really great - even if I can't build it under Debian 8 at the moment - but he never replied...

If someone with reputation the community can trust is ready to hold bounty-bank - I can send SLM or even BTC to them because I don't have much time to monitor all the technical progress (and my English is not so good, sorry!).

I even can try to find some time and make Russian translations for all needed stuff if it can help somehow.

[AIOS]

Well the idea is new and innovative.
Proof of burn will be to the moon soon.

How? Mining to one wallet? Becaue even if I was mining to one wallet.dat it was more nodes than one if I mined with more cpus. Or you mean that they have motherboard with more than one CPU?

Simply by running all cpuminers against one nodes rpc interface. Don't confuse the wallet miner with the separate cpuminers from OP (check under Slimminer Downloads).
The miners are then started with something like this:

Code:

nice -n 20 /usr/local/sbin/slimminerd -o http://my.slm.node:41683 -u slimcoinrpc -p rpcpassword -S -q -B -t 4

[gjhiggins]

Shouldn't be so difficult to port it or should be?

It uses an extensively modified version  of Abe, for which the trail starts here.

Slimcoin's extended block structure (as described in “Anatomy of the Genesis block”, a new addition to the website-hosted docs, edits, corrections, etc. welcome) impacts Abe profoundly because Abe reads the block data out've the chain, recreates the individual block metadata and tx structures, then stashes the data in a DB.

It is quite nitty-gritty stuff, even had Peter Bushnell hunting for implementation detail.

It's not clear to me yet whether ABE's db structure would need to be changed for this specific usage (but it obviously would have to be changed for Abe to be usable as a block explorer for Slimcoin).

Cheers

Graham

[muf18]

So I guess Coinomi would be our only option now.
Or if you know how to get read ACME, by the app and use it to listen and transmit transactions, that would do the trick too? I must studied throughly specification of Slimcoin, it still is a mistery for me.
