Port scans (what Shodan does) are in a grey area. Actually using the port scan data to connect to a networked service and exfiltrate data is definitely illegal.

Also a good way to go to jail. Please think long and hard before accessing random computers on the internet. The fact that they are unprotected is unfortunate but irrelevant.

This seems quite expensive given that the units are located in Crown Heights. (19 people * 1900 avg rent) / 7300 sqft = $4.68 per sqft Lets look at a typical unit [0] in Crown Heights. We'll look at large units (4+ br) to make it

Better security features for one. Clang supports SafeStack and Control Flow Integrity. SafeStack is much more performant than gcc's stack protectors, and gcc offers no equivalent of CFI.

What are current best practices for configuring replicated PG with hot failover? To be clear, what I want is: - The ability to deploy a cluster of say, 5 replicated PostgreSQL instances - All write transactions go to a single leader, whic

Perhaps this is a nice thought exercise, but please don't use this in production. If you need a reliable distributed lock, use something battle-tested like ZooKeeper.

The real question is when they will release a socketed version. The disadvantages of the PCI-E form factor are somewhat mitigated by the on-board memory, but it would still be nicer to not have to program against them as an accelerator card

Do we know Amazon is actually offering the same prices to people in NYC and Iowa? Seems like they could maximize their profit by normalizing pricing to a user's regional cost of living.

The content is quite interesting, but this paper could use some serious editing. There are typos throughout, and the tone is overly colloquial for an academic context. The paper could also use an evaluation section - e.g. implementing a sol

Perhaps one could even use histograms to estimate selectivity of the query's join predicates to pick a good ordering of joins? This is actually pretty much how a basic relational query optimizer works in practice.

...Except the number of query plans is O(n!), where n is the number of joins. MongoDB's query optimizer actually works like this, which is only tractable because it doesn't support joins.
