How to prevent this
1. Don't use Windows, but we both know you're not going to change that.

This is the only choice that matters. You are a pessimist by rejecting the only logical choice beforehand.

Most people don't need Windows, all they need is a browser, and the likes of Chrome run in Linux perfectly fine. That attitude of yours, i have seen it in decades, and it only ends in grief.

Drop Windows and 80% of the issues are gone. If you need a "games" computer, have both separate. Money and serious things in one, the rest in the other.

Don't bother with dual boot, people lack the discipline to NOT boot Windows (or OSX).

None of your "tips" are really effective under a malware ridden windows computer, because you don't know beforehand the exact nature of the malware. Its not just malware that recognizes bitcoin addresses and change it, there are several more vectors for stealing, such as taking your privkeys/seed words, or hijacking your dns, but to name them all would make a book.

Money handling should not be done with insecure OSes, period.
2602  Other / Politics & Society / Re: Monthly minimum wage: ~$82 is that too much to ask? on: October 07, 2019, 11:43:29 PM
Value of money is different in different places. $100 per month might be plenty for you to live somewhere while you'll starve on some other place.
So the minimum salary should depend on the cost of living.
And you can't compare the bitcoin's price inflation to the inflation of a country. A quick research yielded Nigeria's inflation has average around 11.3. Considering a 12 percentage inflation in last 4 years, the current minimum wage is an improvement from the last one.

No it should not! There should be no minimum wage at all. Why mess with the natural processes that take place in every ecosystem?
You have a need for a worker, you offer him/her salary, you negotiate. If It's too low he won't work for you, if it's too high you'll be losing money and risk going bankrupt or operating on 0 profit.

What happens when the government decides how much you should be paying your employees? If it's too much for you you as an employer will have to look for cuts. You'll fire one employee and divide the work among the rest. Minimum wage is stupid.


This is exactly the way it should be. Minimum wages destroys a type of job, that is too small for a formal wage, and yet brings a type of income or extra income to some people.

Besides my "socialist" country now pays about 2 USD per month, and no one wants to work here anymore. Why work full time where you can earn the same 1 hour playing some computer game online farming?. But now all infrastructure is collapsing as well. More beauties of socialism, nobody fixed the phones so why bother with phones (and the "best" internet here uses the land lines, its adsl).

The irony is that under the pretense of socialism, this country has in fact abolished the minimum wage. But, because there are no freedoms to business or the economy, it is useless for investors. We ended with the worst of both worlds, and the benefits of neither. Free healthcare that doesn't provide healthcare, because there are no medics willing to work for 2~4 USD a month and no country willing to manufacture medicine at those prices? (and the local production disappeared for the same and even more aggravating "socialist" reasons, ie. taking the means of productions, but not letting the workers decide things and not letting them procure whats needed for production or even set up prices for survival of the company, resulting in: closure. Everyone is without a job.

The more you let a government meddle, the worst it becomes. Trust me, i saw it happen in front of my own eyes. If you think things are bad in a free market economy, its only because you haven't lived survived a central planned one...
2603  Other / Politics & Society / Re: What to do about people who believe that stealing is ok on: October 07, 2019, 11:29:52 PM
I have been all over the world and have found that there are some cultures that feel that stealing is perfectly fine.

The solution to theft in most of the world is to discourage it through shame and punishment. But some parts of the world do not really see it as wrong. There is no point in shaming and while it may be technically against the law, it is not really enforced because it's "not that bad".

The thing I notice in these cultures is that every individual takes measures into their own hands to protect their goods and property. They have bars on the windows, razor wire fences, etc. (even the poorest homes are barred up). There is usually someone in the more populated areas when you park your car who watches your car for you (upon receiving payment), etc.

Most people in the west do not need to deal with this and are perhaps lucky in living in a place where theft is not as common.

But the countries where theft is common, people are better at preventing theft. I can see why someone from one of these countries going to the US would think "they just let you walk into the grocery store and take food off of the shelves by yourself...no guards at the door or anything", "people leave their homes unprotected with just windows that can be broken", "look, a perfectly good car with so many parts for the taking unprotected".

I see a few solutions...everyone evolves protection of their own property (either paying for a service or taking measures into your own hands every day of your life). Or it becomes exclusionary based where thieves are not allowed in a certain area and that area restricts newcomers allowing those in the protected area to live without too much worry about their property.

I'm not sure which is the better solution. The first solution sucks needing to worry about thieves every day, the second solution makes people soft and sort of prisoners of their location.

This is funny because my country is technically in the "west" (south of USA), and yet its just like what you describe for "others". And the funny thing is, i traveled once to the east, the far east, and the description fits perfectly what you said about "the west". No bars? No guard checking your bags at the door of the shop? you can actually grab the things yourself? Yup.

My country used to be "nice", so its not like the concept was unknown to me. But in the last two decades or so, it has degraded so much its now the other, more dangerous and miserable type. Yes i remember those nice days, but the young people here never lived those.

What to do with thieves? Well the good old book says... bring the hand guillotine?

In my country theft most almost always involves firearms, because a thief without one has a very high chance of being killed on the spot (or left disabled for the rest of his life). And in many attempts, the victims die. Either because of resisting, or the thieve going nervous, or the police coming and shooting (here the heroic Hollywood cop does not exist, here is "shoot first, ask later" (infamous words or a former President of this very nation). And wait until you learn about the prisons, you don't want to learn about the prisons, trust me. "University of crime" they are infamously named, for the ones that survive it...
2604  Other / Politics & Society / Re: Religion and Morality. on: October 07, 2019, 11:16:58 PM
Hey guys. I've been watching a lot of debates on youtube about this topic where theists, apologetics, philosophers, scientists, agnostics and atheists discuss whether religion has a monopoly over what people perceive to be right or wrong. Guys like WLC, Sam Harris, Jordan Peterson, Frank Turek, Richard Dawkins etc. Go after each other's throats to prove their points and honestly, i think every one of them has a valid argument.

What do you think?

Religion does NOT have a monopoly, but it certainly can help, unfortunately in some aspects it can also harm and leave people misled in darkness.

So, as everything in life, it depends. It doesn't even depend on the religion, but on the person.
2605  Bitcoin / Mining support / Re: Where is everyone getting their wall meters? on: October 07, 2019, 10:55:39 PM
In short no. Most other countries I believe run 220/240 at the residential level, as opposed to bringing it down to 110/120. With fewer plug differences so that's why you find the Kill-a-watt style devices so readily available. What I did to allow for growth and density, was go with 30 amp 240V circuits to a PDU then to my miners. If you want to spend a lot of extra coin you can buy some pretty fancy PDU's but they're not necessary. That's very similar to what my first couple miners ran off, so there's nothing wrong with the circuit as is, for most miners. You can always upgrade down the road.

Most of the world runs 230v @50hz, most importantly, China. And for the most part (except places like China or the UK) they use the Europlug or one of the variants. They all share the two poles, its just ground they just couldn't decide together how to do it, lol. Another chunk of the world uses what America used 50 years ago, or the same they use now, depending on country. Japan uses 100v. Lets not talk about Japan :3

You can probably find meters easily for European use, and then you would need to use adapters. The adapters themselves might be too weak if not chosen carefully, or you could make your own buying plugs and cables.

Yes, that is the reason they are now focusing on releasing the cgminer replacement, bOSminer. Currently its only S9, but not the latest models, and the T1.

Next year when they consider bOSminer stable enough for release, then they will start adding more hardware.
2607  Bitcoin / Bitcoin Discussion / Re: what is the difference between staking and mining??? on: October 06, 2019, 12:43:46 PM

I do not have any idea about staking but I have a little knowledge about mining. If I'm not mistaken mining consumes a large amount of electricity because you need to open your personal computer for maybe almost 24 hrs. I think that staking is the opposite of mining but I'm not quite sure.

Personal (general) computers are no longer suited for mining. You need special custom designed chips to perform that specific type of computation faster than a general computer would, the so called ASIC, which also happens to made the computation several orders of magnitude more efficient (ie. produce more results per watt).

So while yes, you leave computers running 24/7, but not "personal" computers, those "mining" computers were specially designed for that purpose and are industrial type machines which are (usually) unsuited for the home due to power requirements and noise generation from its powerful fans needed to keep it cool during operation.

Only in the very beginning (because there were not specific ASICs designed for this purpose) was mining performed on "personal" computers, it quickly went to GPUs, FPGAs, and finally, ASICs. What drove this development was also the potential profit in mining, which was the highest in the beginning, slowing logarithmic-ally in as time passed.

It all worked as intended, for Bitcoin anyway. The altcoins and their experiments? To be seen. Staking is not mining, its just a form of interest earning. An incentive for you to leave nodes running 24/7 with frozen coins in them.

6th #Bitcoin QR code on a Street Art fresco 🎨 in Paris.

This is a real usecase to support street artists without 3rd parties.

Well this sounds like a modern way of tipping the street artist. And unlike the traditional method, you can do it even after the work is finished. I'm a bit surprised this hasn't catch on earlier, anyone who'd like tips should be adding Bitcoin address qr-codes to their job. You could even use separate addresses to find out which artwork received the most appreciation.

Just make sure to use the lowest transaction fee (1 sat/b), don't worry, the artist won't notice much difference if the transaction takes 1 hour or 1 day, as they are not waiting for it in front of you before moving to the next job...
2609  Alternate cryptocurrencies / Altcoin Discussion / Re: Brave Browser to launch a fully decentralized vpn on: October 06, 2019, 12:25:08 PM
We all know that the blockchain itself guaranties anonymity on its own and now Brave browser want's to integrate it into a vpn service creating a fully decentralized virtual private network which means you don't have to be worried about your data being sold by the vpn providers.

However we all know that everything has a good and bad side and one of its disadvantages is that it gives people who perform illegal activities more freedom. What do you think about it? Do you think it's worth it or not?

I'd rather use Tor, which can be done even from that browser. And with Tor, you have access to resources not found anywhere else, as people running Tor nodes can host their own content, away from the clear Internet. This content is free of censorship, because while its possible to detect Tor users, its impossible to determine what content is seen or provided by each particular Tor user.

Tor was designed for this specific purpose, while VPN is not. A VPN is not a privacy tool, and never was. You are using the wrong tool for the job, it might do it more or less, but not as good (think: hammering with a wrench).

And guess what? blockchain by itself DOES NOT guarantee anonymity. Quite the opposite, in fact, it preserves your traces and prevents you or anyone else from erasing/changing them later.

Imagine if your browser used a blockchain to keep track of your history. Goodbye to clear history, ad marketers rejoice!
2610  Bitcoin / Bitcoin Discussion / Re: What's next for bitcoin ? on: October 06, 2019, 12:03:29 PM
Bitcoin is not controlled by anyone. He is not a company to do charitable actions that will improve his reputation. It uses a decentralized network, it is not a company. Also, Bitcoin cannot be sanctioned, precisely because it is not controlled by anyone.
What's next for Bitcoin? A stagnation of about 2-3 years at this price and then a historical boom.

Definitely not.

Why? Are the governments suspending fiat inflation? No, because they are fools that follow the school of Chicago dogma and fear deflation. Therefore if bitcoin where to magically go stable, its price in fiat would still increase opposite to the induced inflation.

So no, its not that bitcoin goes up, its that the $ € etc go down, but people don't see it.

There is also no reason for a "historical boom". The price is showing a logarithmic curve, it starts with a steep increase in price that slows down as time passes, if anything, bitcoin price increases should slow down, and also the fluctuations, which will always occur because its free, but less and less as it gets mature and goes the way of gold.

Bitcoin (thankfully) doesn't have built in inflation so it can never become "stable" against the fiat currencies. It can be used as a way to escape this inflation and preserve purchasing power, but don't expect to live forever over this. It was fun in the first decade, by the end of the next decade you better have diversified and found another source of income, that preferably pays in bitcoin yes, but not bitcoin itself as a source of "magic growth money".

The "getting rich overnight" thing is over, as it should be. And guess what, no change is needed to Bitcoin, its working fine.

2612  Other / Off-topic / Re: Has HULK grown weak or is it just me? on: October 05, 2019, 05:07:07 PM
And what do the comics say? The movies are not necessarily reproducing faithful the source. And often, they take "artistic freedoms". I thought "The Boys" was too gore in its live action, but it turned out the comics are far more worse, and the actual live action show was toned down. Perhaps its because one medium can transmit more of one thing than the other. Definitely animated 3d gore impacts certain aspects more than 2d.

Maybe with Hulk fights (and any other action scenes) is the same.

So anything not from the source can be changed for various reasons.
2613  Other / Off-topic / Re: What does power do people on: October 05, 2019, 04:53:07 PM
who is agree with this statement  and why Huh

Power make people ( even the good ones) evil..

what do i mean with it =

an honest guy can be corrupted by the power... once a person taste the power , it will transform this person to abuser , haughtiness , invisibility , with or without knowing this self ...

Power corrupts. Absolute power corrupts absolutely, or something like that goes the saying. And its very true.

Unchecked, give someone power and he/she will start abusing it, even if it starts with the best of intentions, it ends in the worst. It has to me limited, in time and extent. The three branches were split for this reason, give two of these to the same person or group, and the trouble starts. They simply overwhelm everything the rule becomes theirs, no matter what. And no one can question them, or else...

And you will notice this in the worst countries. It is true that split powers often limits the speed where changes for good could be made, but the price to make is too great, so this shortcut may end becoming your destruction.

As much as you hate "the system", make sure your proposed changes don't take these shortcuts. But of course you will also want to avoid falling in redtape bureaucracy nightmare that lets nothing be done either.

You CANNOT participate in signature campaigns until you increase your rank level at least to Member. Do not bother, none of the signature campaign managers will accept you, and if you make empty posts with only the contents of the signature, you will probably get your account suspended.

First reach member status, THEN, shop for campaigns. And no, you just cannot choose it, its them the managers who will accept you or not, if they see you do not write quality posts, they won't accept you.
2615  Bitcoin / Mining software (miners) / Re: Braiins OS: open-source mining firmware [S9, T1]. New release includes AsicBoost on: October 05, 2019, 04:02:56 PM
This was already explained on this thread. If you input values the hashboards won't tolerate, they drop to 0 hash, and a bit before that, they may exhibit a high error rate.

As i explained before, when this happens you have two choices: Either reduce speed (in Mhz), or increase voltage. Every hashboard is different and no single universal value works across all, you have to try with each of them find the most efficient setup. Various people have successfully underclocked and overclocked the boards. Underclocking maximizes eficiency, but after a point it starts becoming inefficient again until it drops to zero.

So no, there is no graph, and even if you bother to make one, it would only be valid for that specific hashboard. All hashboards react different, they should be "close", but not identical.

The first you have to do is, lower the voltage, until it fails, then go back to the previously working voltage (do this per board). If you decide to lower the speed, then after one step lowering the speed try again lowering the voltage, and so on. You would need to measure power consumption if you are looking to max efficiency. About 80 watt per THs is possible with the S9.

If your goal is not efficiency but simply the lowest noise/power, you have to try with the lowest speed and voltage you can manage without the boards dropping to zero. Remember, no hashboard is made equal. Test each separately. You may find a setting that roughly works with all, but it won't be the most optimum for all, but the one that worked with the worst performer. Which is your worst performer? Until you find it, any values you try will work in some and fail in others...
2616  Bitcoin / Bitcoin Discussion / Re: What do you think Bitcoins biggest vulnerability is? on: October 05, 2019, 03:44:04 PM
What do you think Bitcoins biggest vulnerability is?
The wrong impression people are giving against bitcoin. Most of those people includes the government and people who give doubts to bitcoin. Government is a powerful sector that can give wrong image to people that may cause fud.
Just because the nature of bitcoin is decentralized and volatile, they're using it to bring negative impression on bitcoin. It's always the people who can give vulnerability towards bitcoin, because they're using its nature to attack bitcoin, where in the very first place bitcoin also have its cons.

Yes, in fact most of the first page of this thread is precisely that, except for Franky's intelligent comment.

Most comments are about government fear. Let me spell it out for you: Bitcoin being banned worldwide would NOT stop it. It was designed to withstand that, and it was expected they would do it, but they didn't. There are far more countries accepting or tolerating Bitcoin than those banning it (about 15).

Someone even mentioned security. SECURITY? Bitcoin cannot be hacked, it hasn't been in 10 years, and it won't be later. This is also one of its key design features, you cannot tamper with the blockchain, and the theoretical 51% attack is a form of brute force attack, which is deterred by the fact that it would cost more to pull out than the possible gain of seizing the blockchain at that point. This should be obvious, but attacks to exchanges, online or personal wallets, are not Bitcoin's fault. Its each of these people's field. And in those cases, you have to talk about "hack" to those specific things, not Bitcoin. There are historical cases of altcoins being "hacked", and that should give you a fair example of what happens when things are not done right.

Since Bitcoin is invulnerable in code, it can only be harmed cosmetically on the outside, with FUD and lies, something that doesn't directly really affect Bitcoin, but the humans that would or would not use it when being misled like that. Bitcoin is working as intended despite that. Same thing as when governments "ban it" instilling fear on their people, but Bitcoin is still working fine even in those countries, you just have to cover yourself better.
2617  Bitcoin / Bitcoin Discussion / Re: Remember the story of Bitcoin on: October 05, 2019, 03:27:01 PM
I read a number of articles and even read several forums discussing what bitcoin is.

I made this post because many of my friends don't understand what bitcoin really is, and I made this thread to be my Boomark to be read by my friends.

Discussions about Bitcoin are very much discussed on each site if we look for it on "google.com".
But each site certainly has a different view of each site visited, such as:

  • On the wikipedia site I read that bitcoin was discovered in 2009 they said that Cryptocurrency was a form of electronic money and bitcoin was made by a group of people whose identities were unknown.
  • While the blockgeeks site said that bitcoin was discovered in 2008 they said Occupy Wall Street accused large banks of abusing borrower's money.
  • While on the weusecoin site said that Bitcoin was published in 2009 and Satoshi Nakamoto made a statement that he had left the project in 2010, but now Bitcoin has mushroomed in all countries.

In this forum, many have different views about what is bitcoin?
Quote
The Central Bank of Israel considers bitcoin an asset, not a currency. The Deputy Governor of the Bank of Israel Nadine Baudot-Trajtenberg (Nadine Baudot-Trajtenberg), speaking at a meeting of the Finance Committee of the Knesset, said that in the opinion of the Central Bank of Israel, crypto-currencies, including bitcoin are the currency and asset.

I have a question ladies and gentlemen why they think so?

Of the few quotes I read, many were different and had their own views.
However, it is necessary to do your own research according to the criteria of each, so that there is not much wrong in making the meaning of Bitcoin.
Hopefully this will be a reading discourse for my friends.


It was done in 2008 but entered public use in 2009 with that famous Jan 3 block that has the news paper headline of the day. And Satoshi disappeared about a year later, so they are all correct. You are in Satoshi's forum and you can read his/her/their messages by yourself.

Some governments and institutions consider bitcoin an asset because its so different to their concept of money (fiat). In reality it is currency of a different type, not identical to traditional fiat, but not mere asset either.

Of course, if you minted gold coins in your country (again), you could have the argument. Coin or asset? Sometimes hyperinflation destroys the monetary value of (physical) coins, and before they disappear their cost in metal becomes more worth than their printed monetary value, so they are bought en mass and melt for resale (often illegally, but you can't stop the market). So there is one example of a currency becoming asset.

Often there simply isn't any adequate legislation. If you think its an asset, you are missing the whole point, or deluding yourself. But as a politician, it make make more sense that way. Because of the nature of bitcoin, the "asset" concept seems to have merit, but this is only true in the beginning. The more time it passes, the less asset it is. Of course, being deflationary, it will always be a way to preserve value, as opposed to fiat losing it every year on purpose by those that control it.

Thankfully, no one controls bitcoin, and anything politicians decide in reality changes nothing of Bitcoin, its code is written and executing as intended.
2618  Bitcoin / Bitcoin Discussion / Re: Popularity of BITCOIN on Twitter Declining? on: October 05, 2019, 03:10:39 PM
Bitcoin isn't discussed as much on Twitter as those altcoins who have gangs bumping up the posts and retweeting them all over. I see Bitcoin more as a pure cryptocurrency, like the King of this new industry. Even back in the old times when alt season was a thing, the whole CT was exploding with tweets about "moon shots". Well, now that's not the case anymore isn't it?...

We have transitioned to another phase where only legitimate, valuable cryptos will succeed and not any useless piece of token.

Well I'm not that confident about the altcoins, so far they have failed to improve on Bitcoin, there is always some mistake either in code or in human handling. Of course, those "gangs" are paid, most doing it because a campaign is going on, which is yet another reason to ignore twitter. Besides, there are services involving the sale of tweet followers, etc, so its all a facade anyway.

Altcoin market is saturated, its been so for a good long while, perhaps people noticed, perhaps not. From time to time they seem to make a comeback to fade away into oblivion.

so just flashed braiins os , i can ssh in but cant get to the web interface,

can anyone advise me of what to do, at the moment the control board is not in the miner
as i was flashing it , booted from sd , ran the ssh install command , completed
still cant get into it from browser, i can ping it and ssh ,

are there some commands i can run and post the results to get a better understanding
why it wont let me in,  this is my 6th miner flashing braiins , all the other 5 were able to boot and
access through browser, using the same image

But can you boot using the sd fine there? Then there could be a problem flashing into nand. You can try flashing it again, or revert the nand to factory firmware and see if its still working normally (the nand).

Normally you don't have to do anything else. And you can install into nand using the Web UI, but your command is supposed to do the exact same thing. Try force reinstalling the package firmware (opkg update ; opkg install --force-reinstall firmware) and see if that makes any difference. "Removing" the firmware package should in theory reset it as well (you will find its reinstalled with reset values).

Is this an s9j ? Some of those are exhibiting issues when flashing into nand, but work perfectly fine using the sd card. You don't have to flash into nand to use bOS, you can always let it run from SD.
2620  Bitcoin / Bitcoin Discussion / Re: Bitcoin Nodes in Space? on: October 04, 2019, 09:35:34 PM
As of now, Bitcoin is the cryptocurrency with the most nodes available worldwide. It's been doing well with only 10 years since its inception. However, I believe that in order for Bitcoin to reach true censorship-resistance and reliability, it needs to expand in areas far beyond reach. It would be nice to have Bitcoin nodes distributed across space in order to be prepared for any catastrophic event on Earth. Imagine having Bitcoin nodes on the Moon, as well as, planets like Mars and Venus. This would allow Bitcoin to stand the test of time for generations.

However, it's yet to be proven if this solution is viable after all. What are your thoughts? Huh

With current technology, the main problem would be the latency. To the moon its measured in seconds (not milliseconds), to Mars in minutes, half an hour to an hour. Syncing the blockchain on a solar system wide level would be very difficult, not impossible, but tricky. You could easily have two blockchains running in parallel on Mars and Earth at the same time for long enough periods to do harm. This is definitely something that was not in Satoshi's mind.

One promising future technology that could fix this, is communications based in the properties of quantum entanglement. So yes, not all "quantum" stuff is evil, quite the opposite in fact.

The reasoning about a catastrophic event is unnecessary, if such thing occurs there would be far more pressing issues than keeping the Bitcoin network alive. No, but if in a few centuries later humanity starts populating the system, it becomes important. For interstellar distances you can pretty much forget it, you would be fighting against time itself... Unidirectional communication could be theoretically possible thought.

I can imagine a future where some colonies are setup both in space, such as artificial places at lagrange points, and in some suitable places like Jupiter moons, Mars, etc. As i said earlier, without quantum entanglement communications take minutes to hours to reach points. Even communication from earth to earth using satellites is laggy due to the distance it takes to reach orbit and back, or if needs to be relayed further. This is a physical issue, nothing can be done to lower the latency (short of quantum entanglement), bandwidth/bitrates can be improved, but not latency the speed of light (assumed constant) is in the way...

Did you know? Light from the Sun takes 8 minutes to reach Earth? Yes light, just a different wavelength... But the Sun is in the center, what you do when Earth is opposite to Mars? You already have those 8 minutes plus the longer distance towards Mars... And when the astrophysics start measuring in LightYears, better get ready because that's actual Earth years that light takes from point a to point b... Before taking in consideration time relativity.

Don't worry, if we don't go extinct, our descendants will have fun figuring clever ways to overcome this. Most fiction and even some science-fiction tends to ignore this. Star Trek instant bidirectional communications with Earth? They better have full dominance of quantum entanglement, else...
