A Python program implementing and exploiting the Minsky Turing machine considered in the paper "Intrinsic Propensity for Vulnerability in Computers? Arbitrary Code Execution in the Universal Turing Machine" as per CVE-2021-32471.
Yep, that's right folks. We're finding CVEs in textbook examples of the most basic computers possible.
Starbucks has around $1.6 billion in stored value card liabilities outstanding. This represents the sum of all physical gift cards held in customer's wallets as well as the digital value of electronic balances held in the Starbucks Mobile App. It amounts to ~6% of all of the company's liabilities.
This is a pretty incredible number. Stored value card liabilities are the money that you, oh loyal Starbucks customer, use to buy coffee. What you might not realize is that these balances simultaneously function as a loan to Starbucks. Starbucks doesn't pay any interest on balances held in the Starbucks app or gift cards. You, the loyal customer, are providing the company with free debt.
A very clear explanation of a complex financial problem and gaps in hedge fund regulations.
Exclusive research and expert insights into a year of work like no other reveal urgent lessons for leaders as hybrid work unfolds.
When viewed in this light, the nature of NFTs becomes quite clear. An NFT is a mechanism by which an artist can publicly attach their cryptographic signature to a digital work of art. In other words, it is a technology that supports in the context of digital arts the same kinds of signed editions that have existed in fine art photography for most of a century.
A much better explanation than this NYT article.
To understand why inflation is so worrying to so many people, you could look at price charts for lumber or used cars or New York strip steaks. There is no doubt that the prices of many of the things people buy are rising at an uncomfortably rapid rate.
But inflation isn't so scary if you focus on the precise mechanics by which the value of a dollar changes over time — and how it might affect you. In an inflation-scare moment like this one, you can boil that down to five essential questions.
Nasdaq's computers can only count so high because of the compact digital format they use for communicating prices. The biggest number they can handle is $429,496.7295. Nasdaq is rushing to finish an upgrade later this month that would fix the problem.
32-bit numbers, man.
It is true that Zoom religious services are fundamentally inadequate. This is not a criticism of the clergy and lay leaders who have put in tremendous creative effort. In a sense it is an indictment of the very idea of what we look for in church, and a chance to realign our perspective. That is because even in-person services are, in a sense, inadequate.

Instead of encountering the transcendent, we bump against the limits of human talent.
In our ever changing distributed world, there are lots of ways for applications and services to communicate. Which means there are lots of ways to break them as they inevitably evolve.
Good tips for backwards and forwards compatibility in distributed systems from the team at StackOverflow.
We all automatically gravitate towards the assumption that we are justified by our level of sanctification, and when this posture is adopted, it inevitably focuses our attention not on Christ but on the adequacy of our own obedience. We start each day with our personal security not resting on the accepting love of God and the sacrifice of Christ but on our present feelings or recent achievements in the Christian life. Since these arguments will not quiet the human conscience, we are inevitably moved either to discouragement and apathy or to a self-righteousness...which falsifies the record to achieve a sense of peace...
