Yeah, those real-time notifications of "{User} has done {Action}" always raise my suspicions that the website is a scam.

Since they are almost always on dubious looking ecommerce sites, or scammy betting or crypto web applications

Once it's backed with a scripting language like Python or Lua it will be a very compelling Flash alternative (even though Flash is long dead now).

Since it runs in the browser, I suppose javascript will be the obvious choice.

Is it still a viable option for designers to use the last non-recurrent-subscription version of Adobe Creative Suite?

Or in 2021 is Affinity Designer and Affinity Photo just the best single-purchase option right now?

Would this technique have been faster?

A single pass: paginating through all entries in the bucket without deletion, just to build up your index of files. And then using that index to delete objects in parallel.

Nice! very easy on-boarding/signup flow. The only hiccup I had was on the first screen for signup, the Facebook panel is so prominent (while the email signup is far less so) that I thought the only sign-up option was to use a Facebook account... almost closed the tab and moved on.

Good suggestion! We have Twitter log-in planned, so we'll have to rework the design anyway.

Could you expand on this? What security vulnerabilities does Exim4 have that you'd avoid just by choosing Postfix as an alternative?

Postfix has a very clear separation of concerns and least privledge in the use of lots of helper daemons. Exim4 doesn't not have this architecture and is less secure because of it.

Honest question (I have no actual ASIC experience, I'm just curious)

Where are you getting the USD1500 price tag, I've just done a quick search and I only found a bunch of S9 Miners (Bitmain Antminer S9) advertised for over USD6000 on Amazon.

The batches sold and shipped in Nov were priced $1500. That was the price when buying directly from bitmain.com. Since then Bitmain hiked the price: the latest batch released yesterday (now sold out) was priced $2300. But yeah, since Bitmain's batches sell out in minutes, S9s often reach ~$5k in unofficial resale channels.

Are there similar services or sites for guidance or mentoring on devops and system administration problems? Or could the options already suggested here: https://www.codementor.io/ and https://www.airpair.com/ also be used in this way.

The date for completion on your book is December 25th. Is that DEC25 2017 or was the slated date DEC25 2016 and things have slipped a little?

Things have slipped as things do. :)

I should update that, but I've been busy improving the content and building better examples and learning how to do better video so I can do justice to the planned upgrades.

Do publishers act as a reliable source for validating your idea? or do you rely purely on your audience, if you can validate your audience directly then you'll be able to get a far more accurate prediction of demand for a book than from the opinions of a publisher's agents.
