We're about half way though Australia's first Amazon Prime Day and there have been plenty of good deals on offer. But in the midst of the offers made by Amazon and its partners, there's another aspect we ought to consider.

Warehouse workers across Europe are on strike, protesting the company's treatment of staff in fulfilment centres. These allegations have dogged Amazon for some time, not just in Europe but also in the US. Should we skip Prime Day and support these workers?

Not everyone is completely enamoured by diamonds for engagement rings, no matter how culturally ingrained it is to wear one. But the reality is, not all stones actually work for a ring you'll wear day in and day out for the rest of your life. Here's how you can pick a ring that will last through the good and bad without turning to the hardest rock of all.

Welcome back to Mid-Week Meditations, Lifehacker's weekly dip into the pool of stoic wisdom, and a guide to using its waters to reflect on and improve your life.

Welcome back to Mid-Week Meditations, Lifehacker's weekly dip into the pool of stoic wisdom, and how you can use its waters to reflect on and improve your life. I'm filling in for Patrick Allan, and because it's Evil Week, I'm taking a break from the ancient Stoics and consulting Renaissance philosopher Niccolò Machiavelli.

A panel hosted by the Australian Computer Society (ACS), featuring Liz Bacon (a past President British Computer Society), Marita Cheng (Founder/CEO of Aubot and winner of Young Australian of the Year), Mike Hinchey (from the International Federation for Information Processing) and Anthony Wong (current President of the ACS) discussed what AI is and how it will impact the IT industry and society.

The rise of the selfie has driven a rift into society, bringing up a surprising number of issues over gender, class, age, religion and race. Wired's Jason Parham explores some of these in "When the Selfie Turns Sacrilegious", an essay on taking selfies in sacred or serious places such as mosques and art installations.

Last week, a post written by programmer and teacher Bill Sourour went viral called "Code I'm Still Ashamed Of". In it he recounts a horrible story of being a young programmer that landed a job building a website for a pharmaceutical company. The whole post is worth a read, but the upshot is he was duped into helping the company skirt drug advertising laws in order to persuade young women to take a particular drug. He later found out the drug was known to worsen depression and at least one young woman committed suicide while taking it. He found out his sister was taking the drug and warned her off it.

Other programmers have since come out to share their own experiences.

You might think buying cage-free eggs is in the best interest of chickens, especially if it forces battery farmers to change their practices. The total abolition of caged poultry farms would be seen as a major moral victory; at least for the chickens. But what do the chickens think?

As a philosophy professor who’s worked on food issues for my entire career, I’ve come to believe that questions of animal welfare are more complicated than they seem at first glance. It’s not a clear choice which of the possible living conditions for egg-laying hens – furnished cages, cage-free systems, free-range setups – serve them the best.

Believe it or not, not all hackers are malicious. Ethical hackers are experts hired to support organizations and governments and keep their systems secure. These ethical hackers provide expertise to protect citizens and regular people from malicious hackers. We recently sat down with one to learn more about the most effective tactics and strategies you can use to protect yourself from malicious hackers.

The emissions scandal that has rocked the car maker Volkswagen has again raised the issue of ethical standards in the tech industry. Reports so far say the company is pointing finger at the “unlawful behaviour of engineers and technicians involved in engine development”. But that’s led to questions about the strength of any codes or practice or ethics that such operators are supposed to comply with. So are such codes any good or are they just words?

Many millions of people throughout the world will illegally download the fifth season of Game of Thrones, launched this week by HBO. Legally speaking, what they will be doing is a violation of intellectual property rights, or "piracy". But will they be doing anything morally wrong?

Evil comes in many forms -- some less obvious than others. Today, we want to talk about a tricky kind of evil: when are loopholes, exploits and "gaming the system" OK?

Whether you trust it or ignore it, Wikipedia is one of the most popular websites in the world and accessed by millions of people every day. So would you trust it any more (or even less) if you knew people were being paid to contribute content to the encyclopedia?

Australian households currently pay the second highest "honesty tax" in the world at $290 per household per year, levied by retailers to offset the $AU1.86 billion in losses they incur from customer theft.

We're all dimly aware that the smartphones, fitness trackers, tablets and consoles we spend hundreds of dollars on are assembled by workers where people are very poorly paid. A new analysis by Baptist World Aid Australia highlights just how poorly: of the 39 companies examined, only one was paying a wage high enough to ensure workers could meet their basic needs.

A new study into the effects of markets on moral values has found that people are more likely to authorise killing animals when operating within bilateral market-like conditions. Participants were given the option to either receive no money and to save the life of a laboratory mouse, or to earn money and accept the killing of the mouse. The results show a clear link between markets and eroded moral values.

Plagiarism at university is a time-old scourge. Some would have us believe it can be sought out with ever-improving technology, and with more consistent vetting of student essays with the latest detection software. But beneath these appeals to superior forensic intelligence lies an unhappy fallacy -- that a technological fix can address a moral problem.

It's no shock that people with more money don't wait in line as long: they fly business class, get into private hospitals and hit the VIP queue at nightclubs. But have we gone too far in allowing "market forces" to determine how long we wait?

Arguments are raging worldwide about whether media organisations, including newspapers and television stations, should be more tightly regulated. An independent assessment of Australia's media argues that newspapers need much more effective regulation than currently exists and that a new body should handle this, but also suggest bloggers should be included. That's a reasonable suggestion for large blogs, I reckon, but it could be fiddly to implement.
