4161  Bitcoin / Electrum / Re: Electrum's new Update Notification in action on: February 14, 2019, 08:22:19 PM
Electrum version 3.3.3 included a new feature that will inform you when there's a newer version of Electrum available.  Today a newer version was made available for download, and here's what to expect if you have the notification feature activated.  

The notification setting can be changed by going to Tools> Preferences> General.  You should see this:


I'm glad that this was made optional. If anything, this whole issue was caused by a nag message due to a wrong design decision to allow Electrum servers to send nag messages to Electrum clients. The fact that this nag screen also rendered html links to be clickable only made it worse, but it was a design mistake to allow the nagging in the first place.

Now perhaps a means to white/black list servers...

Leaving it undefined (commented out) bitcoind outputs (and logs) this:
Using at most 125 automatic connections (1024 file descriptors available)

If 1 (either bitcoin.conf or -maxconnections=1, it shows this:
Using at most 1 automatic connections (1024 file descriptors available)

Using "2000" like the OP wanted, it shows this:
Using at most 865 automatic connections (1024 file descriptors available)

So to clarify, this value means: How many nodes i let connect to me, while I'm always connected to 8 nodes regardless?
4163  Bitcoin / Bitcoin Discussion / Re: Bitcoin ATMs doubled every year since 2014 on: February 14, 2019, 12:52:41 PM
That's a great statistic, as posted above it certainly introduces
now people to Bitcoin and Crypto, it also makes it accessable
and easier to purchase although im sure there is a premium.

I know if I had access to an ATM in my local town I would use it
every week after my wage landed.

Would anyone here use one if they got the chance?

No because doing the same with localbitcoins or some other exchange would be much cheaper (fees). Also my country's garbage fiat would fill the poor thing safe box before i could even manage to buy 0.01 BTC. 36 USD would need 216 banknotes of 500 VES, which are rare btw, more likely 5x that using 1080 banknotes of 100 VES. Next month is probably double that...

The irony is, the poorest the country's fiat is, the less useful an ATM becomes. Only those countries with a "strong" fiat money, where a single banknote can buy plenty of satoshis, an ATM makes sense. But in those countries there is little incentive to do so.

Just like electric cars where the gasoline costs nearly nothing.
4164  Bitcoin / Mining support / Re: Quiet Antminer S15? on: February 14, 2019, 12:31:33 PM
From where I stand and without an actual machine I  front of me, there are two ways I can think of reducing the noise of the PSU fans.

1) Remove the grill on the exhaust side and add two exhaust fans. I'll put a fan speed controller on all of the PSU fans to determine how much slower I can get them to pull as much air as the two faster stock ones. If I can get them 2-3000 RPM slower, that should make a big difference.

2) Replace the two 50mm fans with a single 120 mm one on a shroud. Or maybe block the holes on the two small fans and install a 120 mm fan on the side of the case. Not sure about that  I don't know how the PSU is configured inside. That one might not be possible.

I don't know if that PSU is monitoring the fans and needs to read rpm values, that would make things a bit trickier if you remove them, tho in principle i would agree. Bigger fans always moves more air making less noise at the same rpm.

I don't understand the "block the holes" part, that would be like removing them but leaving obstructions to the air flow.

You will want to run it in "enhanced low power mode" or if Braiins OS gets ported, underclock it.
4165  Bitcoin / Mining support / Re: Testing a 220VA Wall Socket? on: February 14, 2019, 12:18:58 PM
I live in an apartment. With no access to the breaker box. So if I want to mine with an Antminer S15, I have two options:

1) Buy a step- up converter to get 220 V out of the regular 110 V wall socket. Not a great idea as this would cost more what with the cost of the converter. And it's probably going to cost more in power too.

2) Share the stove's 220 V socket between the miner and the stove. I have to make sure the stove can still run if I want to keep the wife for one more week. I could also get a 110 V hot plate and let the 220 V socket supply only the miner. But if I can have both the full use of the stove and the miner running, I might keep the wife around for an other two weeks.

You are wrong on both. Either forget the stove, or forget the mining. Also you might find the same type of socket for clothes dryer or air conditioner. A step up transformer is big no, if the miner needs 8a with 220v the transformer would need at least 18a (or more), i think 110v circuits are usually capped at 15a (tho there are exceptions) but you would need to inspect if your house wiring and breakers can handle that load (and the transformer won't be cheap either). Remember, if you have a 20a circuit, the max that can handle is 16a constant load (80% rule), so no.

Do you know of the importance and delicacy of running an asic miner? Imagine you buy a 220v air conditioner, how do you plug it? You cannot share the "stove" circuit, you need a separate circuit from the breaker box.

So you say you have "no access" to the breaker box, what do you do if you make a short circuit? The breaker box must exist somewhere.
If you can use a gas stove instead, that would release the stove socket. Buy that if you still want to run an asic miner. You are worried about your wife? Wait until she hears the noise...

Technically its not impossible to "share" the circuit, but everytime you turn on and off the stove you are likely going to damage the PSU on the miner, so don't. Perhaps take apart the socket and put a small sub breaker in there. It could be useful if that circuit is, say, 50a rated and your stove only needs 20a or so.

What country is this anyway?

A better solution is you install your own sub-breaker panel from the main panel and redo your circuits "locally" (inside the apartment), exactly what you don't want to do, you must. It is weird that whoever built that apartment, didn't do it that way.
4166  Other / Beginners & Help / Re: [FOR MERIT] when was the word "halvening" created. on: February 13, 2019, 08:25:45 PM
Dogecoin talks about 'halvening' in 2014.

Yep, indeed they did. I can certify that Smiley
And for the good skills and patience in research I'll also give you some merit.

I was right there on IRC, tho i didn't pay much attention why they called it halvening instead of halving, but whatever, it was "party time!".

I did learn at that time that it meant miners would get half for finding a block... Dogecoin exhausted all its "halvenings" rather quickly and almost nobody was mining it anymore anyway...
4167  Bitcoin / Development & Technical Discussion / Re: Number of connections on: February 13, 2019, 07:30:04 PM
Hmm so if i specify maxconnections=1 this means i have 8 OUT and 1 IN correct?

But if i query bitcoind (also written in the wiki) it shows this:

Quote from: bitcoind -?
 -maxconnections=<n>
       Maintain at most <n> connections to peers (default: 125)

So where did your 8 come from? I did read in the wiki that, when you can't get incoming connections this goes down to 8.

Quote from: Setting up a Tor hidden service
If you use a Bitcoin full node over Tor, then usually it will only be able to make outgoing connections. Therefore, you will only get a maximum of 8 total connections.
4168  Bitcoin / Development & Technical Discussion / Re: Number of connections on: February 13, 2019, 04:25:04 PM
While we are at it, Can someone tell me the effect of setting maxconnections=1? Does it become half duplex or something?
If you set maxconnections=1 then you are allowing a maximum of only 1 incoming connection to connect to your node. This won't save your RAM memory if you are thinking so. Reducing the incoming connections to 1 would reduce the usage of RAM to just few kb. Setting up the incoming connections to very low is similar to not allowing anyone to download your content even though you are seeding a file after successfully downloading it. As per Gavin's reddit post if you are limiting your incoming connections to a very low value (say 1) you are probably not helping the community by running a full node. Then there is no need for running a full node after all if you are not allowing anyone to connect to you.

Setting up your maxconnections to insane levels like OP is also not a good idea. You are thinking of contributing to the network rather you are destroying your own PC by overloading them. If you really need to connect to more connections then you could manually increase your file descriptors by using the ulimit command.

The comment in bitcoin.conf says:

# Maximum number of inbound+outbound connections.

This is why i am confused about the value 1.

Now for bigger values, does it pick half for inbound and half for outbound, or something else? Ie. does the value 2 means: 1 in, 1 out? Or it could be 2 in only, later 2 out only, later 1 in 1 out?

If there were separate values for IN and OUT it would be more clear to me, but you are saying this means INcoming only?
4169  Bitcoin / Electrum / Re: 2-12-18. I tried to send 6 bitcoins and then received a popup message. on: February 13, 2019, 12:33:49 PM
This is the message on their web page.

Warning: Versions of Electrum older than 3.3.3 are vulnerable to a phishing attack, where malicious servers are able to display a message asking users to download a fake version of Electrum. Do not download software updates from another source than electrum.org. In order to reach users of vulnerable versions, we have started to use the same vulnerability, and to direct them to electrum.org.

So again, what happened was i received a popup window that it is mandortory to install the latest update due to the hack. I pressed install update link on their page. and after 30 sconds eletrum shut down. and wouldnt open again. i tried to reinstall it and wont work.

now.. i went to my phone. installed it just now on android. restored my seed. and my bitcoins are still there... yet i installed the update just now? gonna send my bitcoins out to another wallet to be safe.

im just worried my pc  now has a key logger? or maybe i am ok. because my coins are still there.
You said “Electrum auto-updated”, so what does that mean?
Are you saying that you went to Electrum.org, downloaded the new update and installed it? If that’s the case, then it’s ok.
Where exactly did you press this “install update link”? AFAIK, there is no such option in Electrum.org?

a pop up window and i cant remember what it said. but it said "due to a major malice in versions of eletrum older than 3.3 we are forcing users to install the latest update  to send coins out. Press here to update now " And I pressed the link. and then 6 bars loaded as if the updates were being installed and then it crashed.

it never opened up a new internet explorer page that i downloaded.  i pressed the "update now" button and it started updating , then after 30 seconds it crashed or shut down... and i couldnt open it again.

but all my coins are still here...
 i just sent it to my local bitcoins wallet.. im afraid to login to binance in case i am key logged.  but my binance will be good because i need to confirm any coins being sent out in my wallet from my email. and i havent signed into my email since this happened. so hackers can suck my giant dick. for now i am on stand by.

You shouldn't panic. Did you not write the seed words in a physical piece of paper by hand? This is the only thing that matters. You can delete your computer, install fresh, and use the seed words to get back to your wallet.

Practice this with a linux live iso, boot a linux live iso, install electrum and use the seed words and there is your wallet and funds.

If you are paranoid consider installing that Linux in your computer. And use a password manager with a very good password. Never re-use the same password anywhere, the manager can generate random passwords for each site and keep them safe, so you might as well change all your passwords from that secured linux machine.

Why are windows users so prone to click to random spam? Even if it "comes from Electrum", spam is spam. No you don't need reminders to scare you, (twice) sigh.

Electrum is not vulnerable, a true vulnerability would install malware without your interaction. This fake message is meaningless if you don't pay attention to it, close the window and change the server. Unfortunately you fell for it and clicked... Why? Do you click suspicious links from email too?

Well it doesn't matter, switch to Linux today, and hopefully you'll learn better habits from now on.

4170  Bitcoin / Electrum / Re: Transferring BTC from Electrum That Has Not Been Updated? on: February 13, 2019, 12:11:05 PM
Hey all.  So just to confirm.  Would it just be fine right now if i open electrum 3.0.5 as is and then try to send the remaining btc i have in my wallet to somewhere else?  But if i get that message, then i close it.  Then i close electrum.  Then go to the official electrum site and download electrum? 

Right now i just want to get any btc i have in electrum out of it and do not want to use it until later on when there is very little concerns on it.

Also the message that does pop up if it gives you that message, is it a link where if you click on it, it automatically downloads it?  So if you click on it by accident, could you still immediately cancel the download or once you click on that link, that is it?  Or do you have to download it fully and also go through the installation process?

You will be fine sending from the old version. If you connect to a fake server, when you try send the funds you get a scary message telling you to upgrade, go to electrumfakeserver yadda. Just ignore it; change the server to a legit one and try again.

In a legit server, you also get another scary message telling you to upgrade because your Electrum is "vulnerable" but the broadcast was successful (sigh). Ignore that too, you are done.
4171  Bitcoin / Bitcoin Technical Support / Re: Splitting bitcoin into multiple addresses just in case one gets hacked? on: February 13, 2019, 11:55:05 AM
Is it better to split your btc into multiple addresses in the rare case one gets hacked?
Also, if one of your addresses did get hacked and all your other addresses were associated by having been generated from same seed, are your other addresses at risk (assumming they did not figure our your seed of course).
Do you feel it is foolish to keep too much btc in any one address?
Thanks.

If the addresses belong to different wallets, maybe. Best protection is cold wallets, no computer no hacking. The private key (seed words) is what you need to protect the most. You can put that in a paper written by hand, and another copy of that paper written by hand store them in two separate secure physical places.

If you want to do it with more than one wallet that is ok, but it doesn't improve security much unless those wallets are stored in different places, but then you'll have the overhead of protecting so many places...
4172  Bitcoin / Bitcoin Technical Support / Re: Bitcoin wallet and paper wallet on: February 13, 2019, 11:48:27 AM
I don`t understand, some people say it`s not bad thing to use single address, and some people say it`s not good to use single address.
If i use single address for one transaction, and 2000 people send funds to my address, i lost my funds, because i see that bitcoin core have 100 keypool

It doesn't matter if you don't care about privacy. If you care about privacy, you can make as many public addresses as you want.

You don't lose funds, they are still in the same wallet.

A SINGLE wallet can have (nearly) INFINITE addresses.

PAPER wallet is irrelevant, with the private key (seed words) you can generate more addresses.
4173  Bitcoin / Mining support / Re: Need help installing an antminer s9i on: February 13, 2019, 02:12:18 AM
Hi Artemis3

Thanks for your feedback, I have tried Firefox with no luck and I have only one antminer setup to answer your questions.

Once I logged in the antminer settings page the next step on the Bitmain installation was to click on the network tab, set dhcp to static and to enter the IP address, submask and dns addresses. Apart from the IP address I got from the up reporterin the previous step, the page would not display any other information. I then tried several times to get the IP address again in the hope I would get the MAC address, submask and dns addresses to of no avail.

Could it be possible the antminer is faulty and hence not communicating with the router???

You mentioned bypassing the router? Do you mean connecting the antminer directly to my laptop via an Ethernet cable??

Yes I meant that precisely.

It does look like you made a mistake when you changed from dhcp to static. Do you remember what settings you used?

Or as others have suggested, try to reset the miner and start from dhcp again.

Be careful when you input the static values. A wrong Netmask (ie. 255.255.255.255) could render the miner inaccessible.

You could use an IP scanner from your PC/laptop connected directly to the lan cable (you don't need internet), having that PC with a static IP configuration and a wide netmask (ie. 0.0.0.0) set, it should find it as long as you didn't use the 255.255.255.255 netmask on the miner Smiley
4174  Other / Beginners & Help / Re: Must have web browser addons to keep you a step safer from phishing on: February 13, 2019, 12:49:39 AM
No mention for the Brave browser in a crypto board is quite strange, I started to use it in both PC and smartphone, it's pretty good!

If you are looking for a browser you can just download and run with, with minimal set up or configuration, then I agree Brave is probably the best "out of the box". However, Firefox supports much more advanced add-ons, just a few of which I have linked to above, and also allows a lot of customization and tweaks through about:config and "user.js" configurations. I haven't used Brave for several months, but last time I did it was absolutely horrible for browser fingerprinting. I'd be keen to know if that has changed?

If you don't want to configure Firefox, then Brave is a better choice, but a properly configured and customized Firefox browser is better than Brave in terms of privacy and security.

Brave is a Chromium based browser and can use the same add-ons as Chrome.

My main browser is actually Waterfox, a Firefox based browser. Of course you can use Firefox add-ons (both old and new) with it.
4175  Other / Beginners & Help / Re: How much is Bitcoin's value when I buy a product? on: February 13, 2019, 12:35:04 AM
I know how calcolate Bitcoin’s value in my currency (EUR)

My question is about to find a right prices when I buy or sell.

Example:

If I want to buy a TV and pay with Bitcoin
That TV cost € 100.
What’s BTC price?

At now BTC price is € 3100, the TV cost is: 0,03... BTC

If in the next two hours BTC value goes up of € 1000 ( € 4100) the TV cost will be: 0,024 BTC

So, price of a products that I want buy or sell depends at the time (seconds, minutes, Hours)?

The price is determined by market price, and it changes all the time. You can take a look at bitcoin exchanges, or use one of several online calculators.

The price fluctuates in real time by people buying and selling in the world, 24/7.

How you ever needed to buy or sell US dollars? How can you tell the price in Euros? Same thing...
4176  Other / Off-topic / Re: Russian Intranet Censorship on: February 13, 2019, 12:22:05 AM
Russia is doing a little experiment.
What are your thoughts on this? What can Russian people do to circumvent this kind of censorship? As long as the wires aren't physically disconnected, people will still be able to access the broader internet through TOR or a VPN, but most people don't use TOR so this still has a massive effect on these people.

In the event that somehow the physical wires were disconnected, how would Russians be able to access the global internet? Mesh nets? Satellites?

If it is the same technology used by Maduro in Venezuela, you can still use Tor if you stick to obfuscated bridges (obfs4).

A full airgap is what they have in North Korea, they have a national LAN and they copy the things they approve from the internet in. Only in that case, your idea would be required. In the meantime, its probably the same thing used here, Iran and China, or a variant of. A giant firewall with deep packet inspection.

Obfuscation is important, and most VPN software doesn't do that and is easy to spot. In China people get visits if they use this...

I think both satellites and openmesh technology would help. I'm curious to see how the SpaceX internet by satellite project results. Google also is using balloons to achieve the same.

4178  Other / Politics & Society / Re: Capitalism and the exploitation of labor on: February 12, 2019, 08:15:13 PM
GM workers make $2 an hour in Mexico while they make around ten times more in the US.  Why are Americans paid ten times more for the same exact work producing the same exact vehicle?  I have heard claims that people are paid more when their jobs involve more skill, more risk, or more difficulty, but none of those are true here.  

Well it would also be easy to think that the Mexican’s deserve less because everything costs less in Mexico but GM actually turns around and sells the cars to Mexicans at the full American price without subtracting 80% from the labor costs.

And what is your "solution"? Point a gun to the GM owner and force him to, either sell the cars 80% less value in Mexico, or pay mexicans 80% more? Do you know where that leads? The more you intervene to remove "unfair" profits to capitalists, the less interested they will be in keeping the business afloat.

End result: GM closes, all the "low paid" mexicans back to the streets.

Workers control? Look how far that goes... Good luck. Its not impossible for cooperatives (which are still capitalist) to prosper, the majority fail. Many attribute it to the "unfair" market, but it was in fact their lack of efficiency. What, you wanted them to earn 80% more and still be competitive?

Ah the workers don't have the skill, lets put a bureaucrat to "guide" them... Yeah that will solve it... NOT. I know the results, i have seen them...

Keypoints about socialism:

  • It destroys wealth, never make it.
  • And it does to by force, never by free choice.

Therefore socialism is the opposite to freedom.

It is the workers decision, not yours, to work for GM at that wage. It is their right, and you want to take it from them, because you (who don't or shouldn't work there) don't like it. Socialism, in the inside, goes AGAINST workers wishes and interests.

In a free market society there are plenty of chances to get better wages, NONE by force. In a socialist economy, you get garbage wage, and you can do nothing about it, you HAVE TO take it, or else...

Of course the State should neither intervene the business, neither do anything to "save them". It goes both ways.

Right, and how have these interventions worked out so far? How many had to die because the US was trying to "restore democracy"? If this really gets on the way, you can expect false flag chemical attacks in Venezuela as well.

Do you have any remote idea how many people have to die every year because of the current regime? 20k+.

Since Guaidó's proclamation on Jan 23, only in political demonstrations alone, 35 have been killed by the gov armed forces.. Today is an important demonstration day, how many more will die?

At the same time, this country has the highest crime rate of the hemisphere, with Caracas often surpassing Hondura's worst city (San Pedro Sula) with violent crime deaths per capita.

There is also the deaths provoked by socialist economy. An economy that resulted in no medicine and barely food.

So by both inaction and action, every day that passes without change, more people die. There is more if you dare to search a little. Just search "violent deaths Venezuela"...

There is also documented torture, as i posted in one of the threads...
