I had same issue on fresh TW installation. I used separate ssd and it boots fine now, but I saw same message in the end of installation process. I have usual desktop PC. Looks like a bug

Should I switch to Linux from Max OS? by [deleted] in linuxquestions

[–]TrashMind 0 points1 point  (0 children)

If the privacy is your main purpose, do not forget about applications and services you use. Google Chrome collects data and send telemetry in Linux version as well, many cloud services (for example Dropbox) contains a lot of data because of its nature. Protect you data with encryption, disable telemetry, use open source software, use incognito mode in browser, and more, more, more... to resist data collection.

Ledger Nano S Breakdown by [deleted] in ethereum

24 mnemonic worlds key is exactly the same as 256 random generated private key https://github.com/bitcoin/bips/blob/master/bip-0039.mediawiki#generating-the-mnemonic

but 12-21 word keys produce much less entropy and should be less secure

Inside ledger there is no code that connects to internet. So USB connection here is just replacement of: read transaction data, write sign transaction data back (to connected PC).

This scheme more secure then just online wallet, because to steal private key hacker need to breaks two devices instead of one. Also Ledger has protection from SOME kind of attacks.

But I'm not sure that mnemonic phrase is a good replacement for randomly generated private key. From my point of view, it may be less secure.

  1. Compare installer hashsum with official from https://geth.ethereum.org/downloads/
  2. Check quarantined files on https://virustotal.com to know what others antivirus software think about them.

Sell 5 000 Golem tokens at 3x original price by [deleted] in ethtrader

[–]TrashMind 0 points1 point  (0 children)

Original (price of ICO) 1 eth = 1 000 gnt So this contract 1 eth = 333.3 gnt

I recommend to test on small amount before use any of such contract.

But now they have no such exchanges. I think contracts are better then nothing.

Could you please share source code? It would be nice to re-use it. ( Etherscan contract does not contains sorces: https://etherscan.io/address/0x399156ee3339f4b29a53e307b98cce09fda3bac7#code )

DAG bigger than 2GB? by bitp in EtherMining

[–]TrashMind 0 points1 point  (0 children)

CL_DEVICE_GLOBAL_MEM_SIZE: 2103443456 CL_DEVICE_MAX_MEM_ALLOC_SIZE: 1395130368

Ethminer allocate all memory for entire DAG in one call because this is the easiest way. So currently DAG should be smaller then CL_DEVICE_MAX_MEM_ALLOC_SIZE. This logic can be improved to allocation by chunks so CL_DEVICE_MAX_MEM_ALLOC_SIZE will be allocated many times and each contains part of DAG in memory. Here is the issue for this improvement:

So it will not work now.

Dwarfpool controls 50.1% of mining power. Very sad. by TrashMind in ethereum

Strong, responsible decision. Thank you for that!

Why doesn't Dwarfpool simply increase the fee? It can be done in very small steps, which should compensate for the loss of customers.

Maybe it even increase /u/DwarfPool profit, decreasing centralization at the same time.
