> I agree it's better to ride the trend. :) I think you haven't looked at a 6 year graph if you think the 'trend' is only ever going up. The point of my post was to highlight the risk of (another) crash.

That's a shame. Good news is that any graph of bitcoin's historical price over the last 6 years will serve just as well :)

That probably depends on a bunch of stuff. - PG only added checksums in 9.3 - his disks or RAID controller could be shit or he could be using some 'very cool' filesystem - Some people turn off PG settings for performance that real

Hello, I don't trade crypto and I never will. I'll give you one tip. Look at a graph of bitcoin, litecoin etc. that extends past the last bubble and collapse and ask yourself if you are willing to eat those kinds of losses if they

> Most kinds of damage cannot be repaired on a live filesystem anyway. Even in ZFS. You're totally wrong. The easiest way to demonstrate why is for you to set up a script to randomly write zeros/junk in any amount, at any time,

ZFS has journalling too, in the form of the ZFS Intent Log, where writes are placed rapidly as they occur before becoming part of the main filesystem. The effect is similar to a journal in a journalling filesystem [i.e. to allow recovery an

This entire article can be summarised as 'guy who has never used ZFS and has no idea whatsoever about how it works writes a critique that exposes their ignorance publicly'. Here's a quote: - “ZFS has CRCs for data integrity

I misunderstood what the heck the article was about at first. I hope this quirky analogy may help: "I am implementing a database for a bank. I open a transaction in a special active_customers table when the customer first joins the ban

Thank you for a good summary. The real problem in my understanding was that I wasn't seeing that the article author REALLY IS using long-running PG transactions to as a way to enforce external queue items running to completion (or not)

In the US & AU, I know they use a Theoretical Hold Worksheet which pre-specifies the win/lose ratios and is required for every machine. That worksheet doesn't make use of past wins/loses, i.e. it is stateless. This matche
