gupion Ask HN: What should I offer to my 2 years old to teach him logic?

Maybe it's too early now, I would go with offline games (think of hiding some "treasures" and let him find them).

As time goes by, you might have a look at GCompris suite https://gcompris.net/screenshots-en.html

gupion Ask HN: Tool for Moving Hosting Providers (VPS's)

Exporting the entire VPS's in open format (ova ?) and importing them in the new environment isn't an option? Are the machines too big ?

gupion Ask HN: What open source project, in your opinion, has the highest code quality?

well, if trolling is permitted, I would say that "Hello World" example has the most exquisite code.

in most cases "Hello World" is open-source, but I still don't know if can be named "project"

gupion Ask HN: Looking for stimulating and engaging toys for children of various ages

If you use or can install a linux machine, you might find GCompris as valuable resource. (it has packages for Windows too, but not as feature-reach).

We have also found extremely attractive the "find the clue" type of game, where kids were supposed to find the next small clues hidden in the house (pieces of paper with instructions), based in indications found in the previous ones. The reward at the end was always a source of fun.

However, the most entertaining toys are ones for outside play: kites, bow-and-arrow, climbing walls, diy catapults and the list can continue.

ImageGlass is all I need. Simple, fast and easy to use.

gupion Ask HN: What are the best practises for using SSH keys?

I would also recommend using two-factor authentication (see services like Duo or Twilio's Authy) along with password-protected keys.

gupion A Loud Sound Shut Down a Bank's Data Center for 10 Hours

While being directly affected by the outage (could not make card payments on Saturday), I have noticed that none of the communications team was clearly aware of the situation. Here are some facts: - the first public announcements - FB news and tweet confirming the issue have been posted at ~17.25-1735 local time, after four and a half hours - there was a lot of wasted energy on excuses and social-media damage control, while no clear explanation and status being posted - at 17.41 there was a FB response stating that "one unfunctional server" is the cause of the downtime; all services were down at that time - the corporate communication director declares for press "we know about the issue, we don't know the cause of it" - after almost 11 hours, problem is solved

Now the nice part: next day, the bank issues a press release stating that malfunction appeared after a programmed [fire suppression] test.

While accidents can happen, this looks more like "fail to plan is plan to fail" issue, as well as very bad communication.

gupion Ask HN: A spammer is spoofing my email address; what do I do?

There are already mechanisms to prevent the spoofing of legit email addresses. See details below:

DKIM - https://support.google.com/a/answer/174124?hl=en

SPF - https://support.google.com/a/answer/33786?hl=en

Dmarc - https://support.google.com/a/answer/2466580?hl=en

However, implementing needs support from your email/hosting provider.
