Servers are very expensive. It is not cost efficient to buy a server and let it sit idle or turn it off. Even purchased on the used market, a decent server could cost $4000; if you spread that cost across 4 years, that's $80ish per mo

I'm not defending shell, just pointing out how it works. One of my biggest annoyances with shell is that there are these magic programs such as [ that pretend to be part of the language but aren't. If if $var has an exit status (b

In shell, "if" just looks at the exit status of the next set of commands. if ls /path ; then echo foo ; fi works just as well as the sugar wrapping "test" ( [ ] ) or extended builtins.

One observation / warning I have WRT msgpack is that I have seen situations where data getting serialized directly to msgpack can't be rendered as proper json. Specifically JSON requires some proper encoding of characters while m

This is the basic nature of a modern American corporation where the culture of the leadership implicitly believes there is a fiduciary obligation to shareholders to generate a profit. There is a self-selecting process where people promote o

Doesn't that have all the same failure modes as a bank? Audits sometimes don't uncover faults; insurers sometimes don't make good on their obligations, regulatory agencies sometimes freeze funds, etc.

In modern bitcoin, what is the role of an exchange? Do most people hold their own wallet? If you have an offline wallet, what's the work involved with using that cold key to perform a transaction? And for an organization like Tesla,

I love the game, though haven't played in.... a decade at least. I worked at a place where some other people had a diplomacy club and they'd play over lunch or after hours. I decided I didn't really want to know who at work w

I can't think of a reliable mitigation against "heads I win, tails you lose" such as seen in a privately owned rent-seeking utility, but clearly the existing system is going to fail more and more. There are certainly valid cr

There is a big difference between installed capacity and how much is expected for a period of time. For instance, it is not 100% failure that a solar cell outputs no power overnight; that's just the way they work. There is plenty of w

Each mitigation against this sort of risk event has costs. An enterprise that enjoys all the profits of day-to-day success and no consequence of abject failure will minimize all expenses beyond those necessary to keep the lights on most of

How about severe penalties for breaching your SLAs? Can't deliver power? Give customers $X per minute of downtime. Now let's see you assess your risk when it comes to installing heaters and insulation.

I'm not sure where I put my pearls.... Perhaps we could also talk about the outsourcing of risk; those responsible for reliability of the infrastructure are also responsible to shareholders to maximize return, so heaters and insulation

The system I setup would quickly detect p2p (and some worm/virus stuff) and put you in a quarantine vlan (for virus) or just drop 2-3% of your packets (p2p). That particular network didn't have infinite bandwidth... As far as act

This seems like really interesting technology; where is it now? If it was a real thing, I imagine places that run big data centers would chase any operational efficiency available. https://www.frostytech.com/articles/27

Is there something stopping you from using the fips 140-2 box and also using strong software encryption on top of that? I imagine doing so would have the advantage that trivial examination of the device would be impossible.

"Back in the day" I managed a fleet of X terminals. Some were purpose built X terminals and some were old repurposed Sun 3/50 or 3/60 pizza boxes. I also ran a bunch of servers where they booted off of a small internal

A series of errors by contractors and consultants on the California bullet train venture caused support cables to fail on a massive bridge, triggering an order to stop work that further delayed a project already years behind schedule, the L
