It does have one flaw, though, confusing tests for "bug finding". Tests are also a helpful tool for writing code, and will help you lower both MTBF and MTTR.

CVE-2017-9417 Impact: An attacker within range may be able to execute arbitrary code on the Wi-Fi chip

@x0rz "Emoji in URLs are probably a bad idea... probably"

A hacker stole $31M of Ether — how it happened, and what it means for Ethereum Another day, another coin heist. But this one is different because:

Having sounded the alarm bells, a group of benevolent white-hat hackers from the Ethereum community rapidly organized. They analyzed the attack and realized that there was no way to reverse the thefts, yet many more wallets were vulnerable. Time was of the essence, so they saw only one available option: hack the remaining wallets before the attacker did.

Underhanded Solidity Coding Contest Solidity is the programming language for Ethereum contracts. Ethereum is the next big financial technology since Bitcoin (great overview of Ethereum, Blockchain and friends). As I'm writing this, one Ethereum coin is worth $224 dollars. Anyway, back to Solidity:

There is no garbage collector. Dead allocations are never reclaimed, despite the scarcity of available memory space. There is also no manual memory management.

The compiler is riddled with mis-compilation bugs, many of them security critical. The documentation helpfully includes a list of these bugs .... in JSON.

In some situations, the optimizer replaces certain numbers in the code with routines that compute different numbers

For some types, the higher order bytes were not cleaned properly, which made it sometimes possible to overwrite a variable in storage when writing to another one.

Dos and don'ts on designing for accessibility You can download these posters here, in several languages. Be mindful when applying these guidelines:

Another aim of the posters is that they're meant to be general guidance as opposed to being overly prescriptive. Using bright contrast was advised for some (such as those with low vision) although some users on the autistic spectrum would prefer differently. Where advice seems contradictory, it’s always worth testing your designs with users to find the right balance, making compromises that best suit the users’ needs.

Inline validation is problematic Explores some of the issues with inline validation, and concludes:

In any case, designing the perfect inline validation experience is nigh on impossible. Any potential benefit is outweighed by the problems it introduces. Instead put the user in control by showing errors on submit.
