And still … we had fallen victim to one of the largest data breaches ever in higher education. I also urge you to read a recent piece by Quinn Norton, Everything Is Broken ; it talks about this idea of cultural aspects that impact IT security warning: Ms. I am not looking to obtain dispensation. If your institution is like Maryland was—if you are pouring your risk-mitigation efforts into hardware, software, and humanware defenses but are not addressing these other factors in the culture of your environment—you run the risk of having the same thing happen to you.

University entities both administrative and academic areas are hoarders of data.

What's the meaning of the phrase 'Hoist by your own petard'?

We never want to throw anything away. As electronic media storage systems have driven down the cost of storage, this culture has been further enabled. When the budget for storage is not part of the budgets of the stewards hoarders of data, the cost of retaining information is zero.

Ask yourself the question: If we hold on to this data, what trouble can it cause for the institution … and for the individuals represented in the data? IT budgets are always under pressure because IT is often viewed as an auxiliary see my last blog entry. Thus, rather than doing things the way a best-practice approach would suggest, we do them in the best way we can with the funds we have. This is not a pitch for bottomless IT spending. It is a pitch for ceasing to do too much with too little.

Taking a frugal approach may appear to work initially and may work for a long time , rewarding you for that frugality.

But lurking in frugal designs are elements that, when they fail, bring everything crashing down. However, when you add in the costs of the failure that can come from being clever, the frugal approach is no longer a good deal.

A petar or petard is a small explosive device, so to be "hoist with his own petar" is to be blown up by your own bomb as in Hamlet, Act 3, Scene 4, where Hamlet refers to Polonius being destroyed by his own plotting.

It is not a flagpole, so the common usage "hoist on one's own petard" makes no sense. The word lukewarm has a long and respectable history, back to the 14th century. The adjective luke is thought to be an alternative form of lew, or in Old English Hleow, which meant "tepid" or "warm". So "lukewarm" actually amounts to saying "warm-warm", but this sort of redundancy is common when obsolete words are carried over into modern usage.

This prevents psychological adaptation getting used to the noise and increases annoyance. Like so many commonly used expressions, "hoist with his own petard" comes from the quill of Shakespeare, in this case, Hamlet. The Prince of Denmark plans to turn the tables on his former university chums, Rosencrantz and Guildenstern, whom he trusts as "adders fanged", by sending them to their deaths instead of them to his. A 'petard' was a crude kind of bomb with a notoriously faulty fuse that tended to blow up in the face of the person lighting it.

To be hoist by one's own petard means to be undone by one's own devices. It has an earlier meaning from the Latin - less fatal but equally unpleasant: a loud explosion of intestinal gas. A Petard was an early form of demolition charge, effectively a gigantic grenade. Its name comes from the French verb peter, meaning to break wind. It was used extensively during the 16th and 17th centuries. Early blackpowder weapons were notoriously unreliable, and had a tendency to misfire catastrophically, especially given the large amounts of powder needed to blow open a castle wall.

The unlucky engineer who placed one of these devices under an enemy fortification and failed to clear the tunnel in time would find himself blown to pieces. The first recorded use of the expression 'hoist with his own petard' is in Shakespeare's Hamlet, Act III Scene iv, where Hamlet finds the letter bearing orders for his death and alters it, arranging instead for the deaths of his uncle's henchmen Rosencrantz and Guildenstern.

Hamlet says: "For 'tis the sport to have the engineer hoist with his own petard; and 't shall go hard, but I will delve one yard below their mines, and blow them at the moon. The expression has become part of the English idiom, and refers to any situation where a plot rebounds upon the plotter.

To-day a petard of French origin is a small bomb used to blow open a door or a firecracker. In past times it was a wooden or metal box filled with gunpowder used by a sapper un petardier to plant in a tunnel under the enemy's lines. Sometimes the petard when off prematurely with unfortunate consequences for the person carrying the bomb. He was thereby "hoisted on his own petard". The expression was subsequently used to express what happens when a scheme to discredit or damage someone backfires on the schemer.

Petard: Small engine of war, formerly used to blow in door, etc. A 'petar d ' was a machine used to blow a hole in an enemy fort; the explosion would 'hoist' anyone nearby into the air. A petard was an early form of demolition charge, consisting essentially of a container full of gunpowder with a fuse.

The sense in which petards 'hoisted' their targets was that, like other kinds of demolition charges, they blew things up into the air, particularly if, as was common, they were placed in a mine or tunnel dug underneath the target. Early fuses and explosives being less reliable, there was always a risk of setting them off prematurely, in which case the engineer laying the charge might be 'hoist with [in the sense of by] his own petard'.

A petard is an old siege device, which consisted of a hemispherical metal shell containing an explosive charge, and a pole. In some versions the pole was fixed to the metal shell.

Hoisted by One's Own Petard (Origin)

The hemispherical shell was placed against whatever was to be blasted, and the pole was used to brace it in place. The engineer lit the fuse, and braced the pole. In use, two outcomes are possible: either the wall breaks, or it doesn't. In the latter case, the explosive force is taken by the pole, and through it, the engineer, who was thereby hoist into the air.
