Personally, I tend to use the easy-rsa set of scripts https://github.com/OpenVPN/easy-rsa . Initially they used to come as a goodies with OpenVPN, but they are now provided as a standalone project. There are already pac

You can create a firewall handling a 1Gb/s link with OpenBSD, but passed that, it's quite limited. Even with top end hardware, we could not go past ~5Gb/s with simple pf rules and after a lot of tweaking. With FreeBSD or Linu

You can send email using EC2 instances, including mass commercial campaigns (aka "legal spam"...). However, there are a few things to do, more specifically, you must contact AWS to get "clean" IP ranges (fresh IPs, never

Also, Detroit is a really weird case. It's a city that picked at a 1.9M population and was sized to handle that. Then it fell to a 0.7M population. When your city infrastructure and services are sized for 2 to 3 times your population,

And the same can be said about can in fact pretty much be said by any AWS service. The equivalent of an i3 metal is probably around 30000 to 40000$ with Dell or HP, and probably half cheaper if self assembled (like a supermicro server). AWS

I was also looking at i3 instances. But the fact that storage is not persistent kind of puts me off. How do you manage this? Also, how frequently do i3 instances fail?

I've heard a lot of stories regarding security and physical separation. The most funny was a repair guy from IBM or Cray in the 80ies or 90ies was tasked to repair a broken storage array in a super calculator doing some sensitive compu

There was some clearer signs before the crisis that things were not going according to plan. I remember hearing about the subprimes one or two years before the crisis (and I'm nowhere near the financial fields). Also, the amount of mon

Medicine, not that much actually, I think most of the progress we have seen comes from food security and the sanitary movement. With those 2 items, you can basically get to a life expectancy of 70 years in most places, then you add modern m

For those projects, everybody is over-optimistic in their respective bids (some could say they are basically lying...). But that's part of the game unfortunately. However sometimes, it can be a calculated risk, for most projects, somet

Take your estimation of the work to do, multiply it by 2. Surprisingly, it works relatively well to estimate how long the project will actually take.

Not necessarily, imagine for example an embedded OS with only dash or busybox based on Debian. Also, even with bash installed, bash doesn't always behave like sh does. A common example is echo: With /bin/sh on an OpenBSD: &gt
