721  Other / Ivory Tower / Re: The Goal of Building a pyramid, isn't a resting place but... on: September 29, 2022, 11:41:48 PM
I thought the take on pyramid history is that most of the designers and layers were skilled workers.

Aside from that, planting season was probably two months and harvest season was probably the same. There's another 8, why not build a pyramid?
722  Other / Serious discussion / Re: Users Cross Carpeting of Campaigns: on: September 29, 2022, 11:37:45 PM
I've seen quite a few users apply for every campaign in a short space of time and I don't think it harms anyone unless you're referring to it being done a lot and continuously by the same person. At that I'd ask if you had noticed there are some campaigns that only run for a few weeks, I think that's worse than the people jumping from campaign to campaign.

Most managers seem to update their spreadsheets every week and do most of the admin work on that day (with some exceptions) so it'd make sense some users might hop between 3 campaigns if one they prefer adds you on each of those days.

I've worked with a lot of people who chase startup work and you can find even more brutal (/fast paced) relationships there.
723  Economy / Economics / Re: Can commodities return to its price last year? on: September 29, 2022, 09:42:36 PM
I don't know where you're from but I don't think a deflation or rollback in prices are going to be a possibility if your country becomes stable in terms of economy, either the value of your currency gets stronger against dollar or the minimum wages in the country gets much higher to be enough for someone to live a comfortable life and not just survive.

I have had a similar thought to this. A lot of supermarkets have products they make a loss on to remain competitive with other supermarkets in the UK (especially things like milk and bread). I think the same thing will start to happen again later as cheaper products are found the replace what's currently around or people replace things that went up in price with other things.

A lot of the current pricing that went up is likely to be due to oil prices rising too which is something I'd expect to drop after a year or two.

Also depending on your country, your wages will probably rise (emerging economies) or inflation will probably drop or go negative (developed economies).
724  Bitcoin / Development & Technical Discussion / Re: Signature aggregation for scaling - what is possible? on: September 29, 2022, 09:24:43 PM
For example, Alice, Bob and Carol craft a signature ABC to sign a multisig contract.
The resulting signature is a single 64 bit number, similar to Schnorr
Later, Alice and Bob wish to interact with this contract, but Carol is either unavailable or does not wish to participate.
Alice and Bob craft a signature AB and use it to sign a transaction to interact with the previous multisig contract.
This signature is also a single 64 bit Is there any way to verify that AB is a subset of ABC, without any other information, that is extensible to k of n signers?
Even better, is there a signature scheme that gives verifiers information about how many participants k have signed of the original n - i.e. some algorithm which takes AB and ABC as inputs, and outputs 2. Or takes AB...k and AB...n as inputs, and outputs k?

From what I know, you should be able to add signature and be able to verify them (in some way) with a lot of assymetric algorithms.

Generally, you'd need the public keys of A, B and C to verify the ABC's signature.
If you then had that signature you could use it to spend and aggregate that new signature with other signatures (with just the txid being needed to spend that transaction - like already works). You'd probably have to make the transaction ID just be one of the transactions outputs and inputs though as the signature would be in a separate place and unverifiable - from a quick search, this was already done with segwit but still stores individual signatures afaik.
725  Economy / Economics / Re: Africa with so much endowed natural resources but remains the poorest. Solutions on: September 29, 2022, 09:00:35 PM
Western influences;
The West try to influence us so they can keep extracting our resources..

We need to be free of their influence and be independent in our national decision making

Every country will likely have a role to play in influencing each other, both West and East. If you're focusing on one, you'll ignore the other until it's too late to...

This sounds like it could be an outdated view but if it's still being suggested by media there then it is probably propaganda by people trying to stay in power wherever you are...

It's very much a leader saying we're not the problem, someone more powerful than us who hasn't been near us in a long time is.

Technology
We have to invest in technology to improve innovation
Are you inventing this technology yourself or will you then be liable to Western and Eastern influences? If you're not relying on Taiwanese chips, you probably won't get any soon.

We have to explore more of our immense natural resources

Corruption
Our growth is affected by corruption, a transparent Africa will be massive in development..

Leadership, Africa need a young leadership to lead us

We need unify currency to ease trade

We need to bring insecurity to the barest minimum..

If Africa did unify, or at least have stable borders, it could do well from the ground up.

There's no need to initially start working out what you can dig up from below the surface and cause permenant scars on the landscape. Organised and sustainable agriculture would be a useful place to grow from, and then growing industry once food and water stability have been reached throughout the continent or on a community based system.

Young leadership is good as long as they're not too impressionable and have good supports with knowledge on how things can be implemented.

A lot of countries have gotten where they are now because of failed attempts at socialism, China as an example is good proof of how a huge population can become wealthy and developed over a short period of time and the same dramatic change could likely be done elsewhere, it just isn't.

726  Alternate cryptocurrencies / Altcoin Discussion / Re: Three questions for old crypto fans on: September 29, 2022, 04:21:33 PM
Yes it nearly always happens that way.

Things like bitcoin, eth, monero and polkadot are less likely to shift from the top spaces based on market cap (but eth, xmr and dot are still likely to fall compared to bitcoin as all altcoins are and have proven pasts of doing).

There hasn't been that many cycles though too to base things like this off which should be another concern here. There's a chance something could emerge to outshine everything near the top (a few CBDCs or a big tech issued token could cause a few of the top slots to slide).

I used to think 1-10 was low risk and 10-20 was higher risk (back in about 2018) but I think that's changed too.

You could look for what VCs invest in but make sure you actually do your own research - even if it's just taking time to watch a video on it from YouTube or a quick flick through their whitepaper and forum.

I think axie is an example of another coin recently that fell from nearer the top before, I doubt it was reported on much because it was defi gaming and that industry seems weaker than the stablecoin one.
727  Other / Beginners & Help / Re: May "reserve" addresses ever contain any bitcoins? on: September 29, 2022, 03:37:51 PM
I thought reserve addresses were your keypool addresses (addresses that haven't been used yet but might be).

For backup purposes, the keypool used to store 1000 addresses in your wallet by default (I think) so that backups could be done much more infrequently without the chance funds could be lost.

There's a chance this still exists even if you have an HD wallet as the addresses can be scanned through for received blocks to see if there are any utxos designated to those addresses on the blockchain.
728  Economy / Economics / Re: The Bank of England decided to resume QE on: September 29, 2022, 03:27:17 PM
Isn't this the only thing that makes government bonds attractive (that they might be bought back in times of uncertainty like this).

It seems interesting they have a minimum of £5m for buying back bonds as well as having a maximum amount they can invest overall of £5bn - kinda sounds like they'll only buy back 1000, or can companies pay other companies a fee to batch their bonds together into one large bond the bank could then buy.

A 20 year bond sounds long too, I remember it being said pension schemes are one of the main holders of these bonds and that would make sense. I wonder where those funds will move though, if they're just going to be held in cash and the manager wants an exit from the bond or if they'll be converted into stocks/property over time - doesn't look like enough to cause a bubble unless they mess up.
729  Economy / Exchanges / Re: Anywhere to use Paypal dollar on: September 29, 2022, 02:29:43 AM
guys I thought Pay Pal already support BTC? 🤔 there was a time I read this online, true or false?

In certain countries like the US and UK you can buy and sell bitcoin within PayPal itself but you can't withdraw it. You're buying an asset with PayPal having full custody of it (this might take some reading through their Terms and a Conditions) meaning you kinda don't get to own what you've bought in a way and your investment might be devalued if they decide to charge fees for you to hold it with them or they get hacked and can't afford to recover the holdings.
730  Economy / Economics / Re: GPU price in China drop to their lowest level in histor after the ethereum merge on: September 28, 2022, 07:32:54 PM
It's likely that a lot of miners (especially with cheap rates on electricity) will have moved to bitcoin and probably a good suggestion or reason the hashrate has increased since the market has been bearish.

I was just talking with the others in the mining speculation thread and we kind of came to the same conclusion Bitmain is slashing prices (5x) year to date because there is zero demand for new miners. I doubt too many home GPU mines will be able to switch to sha256 ASICs, the power consumption requires a different setup and not your ordinary apartment socket, then the heat, and the noise, you could sleep in a room with 2-3 videocards running, but I doubt you would be able to sleep with a tings that makes as much noise as a Karcher vacuum cleaner.

I was considering places like Russia and China to be able to sell cheap electricity to industries which might be able to facilitate mining too (a lot of places too probably have better rates if you can guarantee the exact amount of energy you'll use or the energy you use doesn't change much - and is a lot).

UK plug sockets are able to handle up to 3000W (electric kettles use about that much). But yes it will have moved some miners with GPUs to other things - obviously there's no chance you'd want an Antminer in a studio flat, I noticed Bybit had an offer on GPU mining software they claim to be good - this was via email so I don't have a reference link - (I'd guess nicehash does too but I'm not sure if there's any additional competition there).

Does anyone anticipate market prices of GPUs rising due to semiconductor shortages? Or is the pure computational and data center segment of the market polarized enough to be isolated from rising demand of more general purpose chips?
I think the pricing of GPUs has already been manipulated quite a bit due to a lack of competition (with nearly all coming from AMD and Nvidia).
There's a chance control units other parts that need to be printed especially will still be expensive (especially if they use cpu parts that are scarce.

It is possible GPU price declines will be temporary. Due to crypto miners panic dumping mining units. Once the excess supply is exhausted, prices could return to normal levels.

Considering recent stories of manufacturers purchasing brand new appliances to cannibalize the semiconductors in them to meet manufacturing component quotas. I feel tempted to call a bottom on GPU prices. Inflation could also contribute to current prices being the lowest we'll see within the short term. Possibly even the long term.

There are still incentives to make games a lot more compatible now with standard laptops/computers but GPUs will still be sought after by a lot of gamers wanting better graphics and lower lag. I think GPUs are still required in data mining though (and things like password cracking/forensics) so I think there'll still be a big market for them - ethereum mining also seemed to force them to become more cross compatible too (so gpus could be used on linux) which might give them an additional market to exploit still.

I don't quite know whether pillages will be done as much as finding ways to encorporate a GPU into a system if it means keeping the costs down (especially if something a gpu has can be used by multiple parts of a system (like power controllers). There might be driverless vehicles and other innovations soon that may be buying up gpus now to be used in their future systems
731  Economy / Exchanges / Re: Anywhere to use Paypal dollar on: September 28, 2022, 04:12:15 PM
As the other have said, PayPal is risky and people using it will likely charge you a high fee (paypal is potentially reversible, bitcoin isn't).

I'd recommend doing p2p trades via bank transfers instead as they're normally less reversible. There are options to use cash deposits too into other people's bank accounts that don't need much information and are normally a lot closer to market rates but there might still be links and you'll have to find an p2p exchange that's widely used in your country too (or with a compatible bank).
732  Other / Beginners & Help / Re: How strong are hardware wallets on: September 28, 2022, 04:03:00 PM
I think the pin you use for a hardware wallet is normally stored in a hashed form on the device so it's possible that that could be bruteforced (especially if it's only 6 numbers long pin with trezor, even if the hashed pin isn't stored).

This is what makes the passphrase significant with hardware wallets as when the device is lost, the passphrase isn't stored on the device and no version of it should be so an attacker wouldn't be able to gain access to your wallet that was generated by that phrase (unless they managed to guess it which is much harder to do if you generate one well).

733  Bitcoin / Bitcoin Technical Support / Re: Installing a Full Node under Linux on: September 28, 2022, 03:33:27 PM
I think Internet bandwidth and a fast(ish) ping is the most important for hosting lightning network channels but a lot route through tor anyway (as well as just generally ensuring your device keeps functioning fast - so you're not waiting for seconds of lag for something to install).

Your initial sync will take a long time and I think it should be able to install on 32 bit systems but that might slow it down further - with the smaller number of registers 32 bit offers afaik.
734  Alternate cryptocurrencies / Altcoin Discussion / Re: Vitalik Finally Released The Book On POS on: September 28, 2022, 02:46:39 PM
Let's hope this doesn't birth a craze of people writing books about the coins they want to produce and waiting for enough people to buy them before they make the coin or something (it's very niche but I'm not saying it won't happen, nor would a coin well designed and innovative actually do badly if a book was written on it during or before development).

It's 387 pages, I'd share but prevents me from downloading or printing and I can't be bothered to get around it.

It'll be available online soon enough probably considering there are so many book sellers/international publishers, it'll probably end up in a lot of libraries soon.

I can't imagine it having new content but it might be concise enough. 350 pages sounds short for a non fiction piece though. 
735  Bitcoin / Bitcoin Discussion / Re: Buying Bitcoin CBDC on: September 28, 2022, 03:50:44 AM
P2P transfers will still likely be quite private (the issuer of the CBDC might know you two are sending funds to each other but it might be harder to work out why - even if the trader did a lot of trades they might have personal uses for that account too).

With exchanges, unless an exchange is awarded one account per person (which could and might happen) it may be possible for the CBDC to track inflows and outflows and work out exactly who you are (some simple things like treating exchanges like mixers and waiting a random amount of time that's a few days and sending an amount close to what's common for that exchange will greatly improve the chances of your transaction remaining private).
736  Economy / Exchanges / Re: Binance Banned on: September 27, 2022, 01:22:38 PM
Try going to binance.com and logging in to your account. If you can't access that, Opera (the Browser) offer a free vpn service you can use to spoof where you are (hopefully - I remember they had a location spoofer but I'm not sure if it's still there). You should then be able to load up binance and login to withdraw funds.

You might want to check news outlets and their support though in case they're only banned for a short time and you don't want to go to the hassle of moving funds around.
737  Other / Beginners & Help / Re: [Warning]: Erbium new crypto password stealer malware on: September 27, 2022, 01:17:32 PM
I can't decide if this is a good place or not for this to be posted since I imagine a lot of these are being downloaded from places like telegram channels? I can't find anything that says where the software would be installed from so I'd assume it's there.

Using a search engine in this case is probably all that's needed to stop you downloading a piece of malware like this though (and clicking on the first non ad). Although perhaps some eth forks like harmony one got a bit confusing (with similar extensions but different networks and two address types).
738  Economy / Economics / Re: Supply and demand on: September 27, 2022, 12:59:06 PM
You can just post threads anyway if you're not sure and they'll get moved or you'll receive suggestions on where to move them if they don't look like they're in the right place..

Here is fine for that sort of thread though (but arguably not for a thread like this which could be a meta topic).

Also if you quote other places in your post remember to cite them and leave links so it's not considered plagiarism.
739  Economy / Gambling discussion / Re: About Casino Licenses on: September 27, 2022, 12:28:25 AM
You need a license to legally serve gambling products to some jurisdictions like the UK and the US.

You don't need one if you open a casino in a territory that doesn't require you to have one (I think a lot do though) and serve countries that don't need you to be licensed there in order to operate. Just search if you need one for your country.
740  Bitcoin / Development & Technical Discussion / Re: [Concept / Question] Bitcoin Hidden Services on: September 27, 2022, 12:21:45 AM
It's possible (ignoring the why we tor already functions and there are other services like i2p).

The closest to something like this is namecoin but I don't know how anonymous that'll make you (or if it will - I've seen suggestions you'll void anonymity by sending funds from your web address to an exchange for example would obviously tell the exchange what you're hosting).
