The We Vibe was the topic of a Defcon 24 talk, Breaking the Internet of Vibrating Things[1]. Was an excellent talk, but I felt it needed more jokes woven in. [1] https://www.youtube.com/watch?v=v1d0Xa2njVg EDIT: grammar fai

Asking for advice is perfectly fine, provided that those giving it have no expectation that it will be followed. I mention this only because sometimes, when advice is given, there's an implicit assumption that it will be followed - &qu

In 2014 I traveled to Ghana for a friend's wedding there. The day I flew back, I had to go through a second, thorough security checkpoint at the gate before I could hope to board my plane. I didn't have anything to worry about - I

I'm actually surprised at the dearth of updates. The cleaner interface is nice for sure, and transcription in Spanish is great (yay internationalization!), but the post is underwhelming overall. There's just vague messaging about

For me, it's hard to speak against the outcome; criminals are being caught, after all. I'm wary, however, to give the government total leeway with technology. It's the issue of giving an inch to someone, and they take a mile:

As an aside, for those looking to understand YARA rules, [1] provides a brief introduction and [2] introduces how to write them. I needed to look it up myself, but seems relatively straightforward if you have a programming background. tl;dr

The way I like to think about it is that the database does not know nor does it care (nor should it!) about the meaning behind the queries you're sending it. It cares about fetching and storing data correctly first and foremost - it ca

They will behave similarly in similar situations. There's four scenarios for 2 transactions: 1) Transaction 1 starts and commits before Transaction 2 starts. 2) Transaction 1 starts; Transaction 2 starts; Transaction 1 commits; Transac

One major difference is that optimistic concurrency control is handled by the calling application and not in the database. Your app should handle the error in either case, but in the case of OCC you end up doing the bookkeeping yourself, wh

I'm in agreement with the other replies here - this seems more useful within a datacenter (and any unit smaller than that, such as an AWS Availability Zone) and not so much useful over the general internet. Too much unpredictability in

The recent speculation about a national registry for Muslims - and what that may look like - makes this even more poignant. The times may have changed, but fear and ignorance have not.

by altendo 10y ago
My tongue-in-cheek solution: put the sysadmins in charge of voting machines. They'll make sure there are several backups, automate testing of all the machines, and an unwavering ambition to prevent data corruption and hacker intrusion.

Right now I think there is a pretty hard reaction to openness and trust. Hopefully we can work through it and make things a little better :)

It depends entirely on where your call to the suicide hotline gets routed. I won't contact police unless there's an immediate threat to the caller or to someone else (in cases of abuse/homicide, the caller might not be the on

This is hard to read. I volunteer at a crisis center, and just reading the description of how the phone volunteer handled the call made me cringe. In my experience, you don't call the cops just because they call the suicide hotline and
