I'd like to hear a third party opinion that objectively compares the science behind both of them.
Thanks for the discount, I'd probably keep using so I went ahead and paid the $25. Even though I have been burned a few times by the "for life" purchases, I don't expect it to last for more than 1 or 2 years ;)
It's gambling in the same sense poker is gambling.
There is skill involved in both, but if you are in it for the short term you will face variance and could lose money regardless of skill.
If you have skill AND play for a long time, then the variance is lowered and it is positive EV.
It is in the site's best interests to actually decrease the skill portion and increase the luck portion. The main reason is because new user's will try it out a few times, lose all their money to the site's sharks and say they cannot win and give up.
Back in the day (/shakes fist at cloud) it was the slashdot effect. Rapid spikes in popularity overloading systems. We certainly couldn't handle scaling up to gmail size all at once. Maybe over a couple of years.
Of course our growth strategy is quality (people willing to pay for a good service quid-pro-quo) over quantity (free service and monetise later via ads/analytics), so we've had a slow steady growth for the entire 15 years we've been operating rather than the viral growth and sell-out/pivot that unicorns are known for.
There's an "average size of humans has increased" joke in here somewhere - both height and girth.
And I do agree to a point. We're very happy to have increasing numbers of users so we can afford to do things like contracting the excellent developer who's working on JMAP support for Calendars in Cyrus IMAP at the moment, as well as hiring people to add new features or improve existing ones.
We do try to stay at a point where we can run comfortably on 50% of our hardware, so we can shut down half our machines at once for maintenance. Redundancy certainly helps - we've blogged a few times about how good it is to be able to shut down any one machine with only a few minutes' warning to move active users off it.
I'm certainly looking forward to spending time again on what I wanted to be doing (Cyrus IMAPd improvements at the moment) rather than battling a DDoS!
Indeed, Gmail maintains extensive protections against peers being DoS'd by Gmail. The number of connections and the rate of mail is closely controlled, because a lot of sites can be taken down just by opening a few TCP connections at once (what are they using, inetd on SunOS?).
But we are waiting for the client, no? If I understand correctly, the client will enable us to install Let’s Encrypt’s certificate on our web server. I assume, “general availability” is when the client will become available for everyone.
general availability means a certificate, that is accepted by all browsers, can be requested and fulfilled. Right now the closest thing we have is a waiting list + very few https servers answering with such certs.
As someone who spends a fair amount of time traveling between countries that drive on different sides of the road... I am always getting the turn signal and windshield wipers mixed up. So I doubt I can use the auto lane change feature.
