By the way, what is a sure way to identify blockchain corruption? Is there a command to make the daemon recheck all the blocks?

For a dedicated server that would be quite inconvenient. You would have to run something that scans the log file for that error, and on finding one, script a daemon stop, delete blockchain and daemon start. Here's a proposal for a new daemon feature: a command that would pause syncing, scan the blockchain for corruption and in case there is some, delete every block starting with the first corrupted one and resync from that point. What do you guys think, is it worth adding? Unfortunately I have no C++ skills, or I would have added this myself. ![Embarrassed](https://bitcointalk.org/Smileys/default/embarrassed.gif)

I'm thinking as time goes by and the blockchain becomes bigger and bigger, the choice of filesystem for a node that handles many connections (open daemon for unlimited wallets) is going to be increasingly more important. You raise two points:
1. data integrity. For this copy-on-write filesystems are unmatched.
2. performance relative to one another being negligible. I beg to differ. Different filesystems handle fragmentation differently and that adds to the significant number of random reads for a node that has to handle a large number of wallet connections. For this I think filesystems without journal like ext2 might be fastest.
By the way, what is a sure way to identify blockchain corruption? Is there a command to make the daemon recheck all the blocks?
I would think God created ECC memory and parity drives for data integrity and you will always lose speed with security and integrity being your number one priority you cannot have both that is just the nature of the beast. The partitions are the lowest denominator that really has less bearing then benchmarks would have you believe. I challenge you to setup multiple partitions and do a weeks real world comparison and doubt there would be any noticeable speed difference. Anyway I have been out of the industry for 17 years and have no desire to research a more specific answer for you but my previous years as a Senior Hardware Engineer is probably good enough for your purposes. Thank you for dropping in and letting us know that you will never own this coin, do you do that for every coin or are we just Special?

When your node gets forked off the network. Since the entire network is synchronized and massively replicated, there is enormous redundancy and inherent error checking. There is no real need to introduce additional redundancy or error checking at the node layer, although for a high availability service you might want to run multiple nodes and introduce some middleware to ensure they are in sync.

After 6 hours, 216 confirmations and counting still no wallet-exchange transfer. Not even a pending notice. After 6 hours too. All I did different was change the ringsize to 10. Is that normal? My other transfers took maybe 2 minutes.

Which wallet are you using and are you using a local node or a remote node? Also, did you try to restart it?

Both the localhost node on 18081 and the node.moneroworld.com on 18089. This morning I noticed the bc is trying to synch but it's crawling. The wallet is also showing a much higher wallet balance than I should have but I can't send a smaller amount that I should have.

except it was debunk, there is no keylogger inside this keyboard... Updated, 11/7/2017, 8:40am PT: An earlier version of the article stated that the keyboard's software was sending key presses. However, in a closer look, it seems that the Cloud Driver software doesn't send the key presses to the Alibaba server but only how many times each key has been pressed. http://www.tomshardware.com/news/mantistek-gk2-collects-typed-keys,35850.html
