please explain how to transfer bitcoin without mining a block, since the transactions are contained there.

You need to take the energy required to mine a block and validate it (a lot, could power a small town), then divide for the few transactions that could be included in just 1 mb.

They impose a size limit on the transactions that can be included, so even if tomorrow the transactions increase 10x, each block could contain the same limited number. Of course, if you only count the electricity used by your machine to send the transaction, it's just a few milliwatts. The problem is all the garbage calculations that need to be done to actually validate it.

I always make fun of this with the coworker that I'm training.

"See, the PDF is malformed and crashes the program. But that's normal, this program costs only €700 per year. When it happens, use this free program to open it, and there's no problem"

For a generic non personalized spam, IMHO it would be too expensive to generate and track millions of wallets. They could have placed a tracking pixel for much less (they didn't, the email is just plain text)

If then it's some targeted campaign, then yes, a dedicated BTC address makes sense as you said

It's a conservative estimate, it's even higher than that

Crypto-biased source: https://www.coindesk.com/business/2021/08/18/how-much-energy-does-bitcoin-use/ (you would expect they downplay the number)

You can just take a calculator and do by yourself the math from publicly available stats https://bitinfocharts.com/bitcoin/

In the past 24 hours a block contains in average only 3500 transactions. Then that block needs to be validated by many other nodes in following calculations.

This is why it's the most inefficient payment method, very slow (only 3500 transactions in ten minutes instead of few seconds), expensive for the user (transfer fees are high) and power hungry

one candidate must be perfectly immaculate and nit-picked on the smallest detail while the other can do and say what the fuck he wants

 

Yes, believable, from all the payment methods available, Greenpeace would choose the most fucking inefficient one, that wastes 700 kWh for a single transaction, that's 100 households!

I have wireless android auto and sometimes I wished it didn't have it, for shorter trips I prefer to have no map, just the car radio, and for longer trips you have to plug the phone to charge anyway because navigation uses a massive amount of battery

There's a default setting that allows unencrypted communication between the server and cloudflare. So they receive unencrypted data, sign with their certificate. Or send with self signed certificate, they decrypt and reencrypt. Or for some reason can download and import on the server their own internal use certificate.

Cloudflare knows almost everything done from your IP address because they're used by the majority of websites. And some websites are using a cloudflare signed TLS certificate so if cloudflare wants, can see the content of the communication instead of an encrypted package

So they know if you have a human behavior (visiting many different websites at human speed and having rests during sleeping time) or if you have a bot behavior (sending millions of requests to the same endpoint at superhuman speeds)

A program that is supposed to make money when you're sleeping by automatically trade currency pairs. Usually they aren't as miraculous as their devs are stating.

It stands as "expert advisor"

I did, because I wanted to run multiple copies of it.

The cracked version was running much more smoothly (10x less memory usage) due to missing DRM encryption

My thoughts on it from a decade ago: https://www.forexperiments.com/2012/10/the-price-of-protection.html

This said, most expert advisors programs aren't really functional, need a human supervision. IMHO the devs make more money from the sales/subscriptions of their software than running their "money making machines". After all, if your "completely automated money machine" actually works, why would you bother in paying marketing, DRM schemes to have other people using it?

they fired the guy that single handedly managed meshcommander https://github.com/Ylianst/MeshCommander

it was a tool to remotely control intel vpro machines, intel's own tool is not as good as what the old ex-employee did in his free time

 

It was a video of someone pretending to tell you a secret: thanks to a new israeli app based on ai, it's possible to make 8000 euro per month with trading by just opening an account with their referral and depositing 500 euro. 100% safe and definitely not a scam.

Maybe not a literal scam but imho deceiving people just because they're going to give you $100 in referral money is a scam

it's because people arrive 1 minute before closing time asking for a task that takes 15 minutes and the employees are rightfully fed with that, because the owner won't pay the extra time

 

I have an old mac with a dying hfs hdd with failing SMART. I copied 2tb of data on an exfat drive but windows only sees only 3 directories and 80gb. Where's my other stuff? Now after I did that long copy session that lasted a whole day, the disk died from stress and the mac doesn't boot anymore. Even if it boots, i don't think the disk can last another full copy session...

Testdisk can show the data, there's a way to tell windows that the files are there?

 

Also: FUCK SCRIBD AND EVERYONE THAT UPLOADS STUFF THERE!

 

I got a new Mobo. Windows installer doesn't see the nvme drive. For some reason the bios has a million settings and are all alien to me.

I took a lot of photos of all the settings, so many unknown entries

The motherboard is from an unknown Chinese OEM and it's using a laptop core i7 but in a itx form factor. I have no idea of the brand, really. The box just says "motherboard" and there's no silkscreen on the PCB (it was very fun guessing which pins were for the front panel). No user manual was included. The bios it says "version: default string"

I hate when OEMs lock down bios settings but here is the opposite, they enabled everything
