[QUOTE=Jeff Railsback;1267325]Just saw that Chandler Smith lost part of his ring finger after a piece of armor felll off a tank and smashed the tip off. Was looking forward to seeing him compete this year.[/QUOTE]

Yeah, you can find pics out there on fb or ig. Nasty. Feel bad for the guy really. :(

[QUOTE=Brad Gerbrandt;1267307]I wouldn't get my panties in a bunch about this. I'm guessing no one on this board has created a website that will eventually have over 1.5 million unique data points all entered by different users. ....[/QUOTE]

I have. It's not hard if you just do a little grade-school math before you start...which I doubt they did. The math I'm talking about it: figure how much data you need to handle at what rate, then double or triple that as a safety margin and design accordingly. Then make sure you test it to insure your assumptions pan out, before you make it public. Like I said, it's not hard and they apparently [I]didn't do it[/I].

David, while I agree that there were a lot of failures with the new website, your explanation shows that you have almost no understanding of what is involved in building significant web applications. It's not just simple arithmetic at all.

LOL... 1.5 million users is not a significant web application.

Depends on your perspective. In any case, you don't actually seem to know what the heck is involved in this, so I'd suggest you stay in your lane.

[B][COLOR="Blue"]Just some basic data to close the subject on the CF application and problems...[/COLOR][/B]

Here is my current thinking: off the top of my head
•Get a 1 or 2 gigabit internet connection.
•2x HA Proxies / load balancers.
•12x physical servers (2x quad cores, 32GB of ram) to run 25 Virtual Machine Apache web servers - 300 VMs total.
•2x memcached Servers (2x quad cores, 32GB of ram)
•2x Master Mysql DB servers, 3x read only slave mysql BD servers
•2x 6TB SAN RAIDs
•All 10GbE or fiber connected...

Figure out the hardware, and how to deploy and maintain it.

As for maintaining this beast, Slack, Rightscale, Landscape, VMware. deploy it on Amazon EC2 as it is much cheaper in the long run, rack it and add EC2 instances if more is needed.

Let me mention some of these general guidelines on scalability:
1.No single point of failure:
2.Have modular SOA architecure.
3.Have a framework to measure performance of your website to gauge improvements.
4.Load balancing
5.Caching - at browser, at CDN, local to a application server, global to application severs, distributed across servers.
6.No-sql DB
7.Optimizing relation DB - indexing, sharding, partioning.
8.reverse-proxy
9.Asynch queuing - Kafka, SNS.

[B]So now back to the Open...[/B]

Question----

Did you think 17.2 was harder than 17.1?

I thought 17.1 was hard as being over 200lbs and doing burpees is not ideal..

Re: 2017 CrossFit Open, Regionals and Games Thread
 
I'm 6' and 200ish lbs at the moment and I found 17.1 very hard. Especially since I am coming off an injury and only got back to training a week before the open. The burpees really killed me. I think I could have gone 3 minutes or so faster if I was actually ready for the open.

17.2 wasn't nearly as bad cardio wise but my arms just fatigued too fast. I'm sure I could have pulled another 20-30 reps out of it if I had been able to prep for the open.

I'm 215 and 6ft. What kills me are the T2B, they take too long to complete so I loose allot of time. My grip was fine the whole time during 17.2. I reckon I could get 100+ reps easily if I could speed them up. I hit 92 reps today.

17.1 was hard on the lungs.... I'm hoping for some max 1rm or something so we have a chance against all these Duracell bunnies :D
