cominatchuon Use rsync to deploy your website

As other people mentioned, if you send the diff by, say, pulling from your git repository, then you can roll back to any tag or revision.

What happens when your 300MB deploy needs to be pushed from your development machine out to 15 different production servers? I wouldn't want to send ~4.3GB for every deployment. Furthermore, a quick deployment time is valuable when a crucial fix needs to be pushed to production.

This is not to mention the space that your 300MB deploy is going to take up on the hard drives of your production machines if you deploy twice a day. That's over 213GB a year per machine, sounds like you would need to start deleting old revisions. Or start just sending the diffs.

takes too long if your project is of reasonable size, why not just send the diff

cominatchuon Ask HN: Review My Site AppTiger.com

you're right i'm fixing that bug now...it looks like price changes do not propagate to all servers at once so the load balancer is causing different prices to come back if you reload an app's page right after a price change happens

cominatchuon How do you scale your web application?

After the easy stuff: move your database to its own server, add a load balancer in front of additional web servers, implement memcached, start splicing your database to multiple servers, continue to add web servers, serve your static files from a cdn

cominatchuon YC Terms are Poor

I would argue that by putting such a high valuation on your advice, people think it's worth more, just as they have a natural tendency to think that they are getting a higher quality shirt if it is priced at $50 instead of $5.

Another point to note is that there is an incentive for all of the Y-combinator startups to say they had a good experience, because if they said otherwise they might be burning the bridges they built (which they would not want to do, even if those bridges are not worth what YC charges for them).

cominatchuon We just launched a new invoicing web app for under 10K. Check it out: Ballpark

The "under 10k" price tag is misleading because it does not include the opportunity cost of the web designers time. In other words, one has to calculate (the hours spent by Metalab web designers * their normal hourly rate) and add this to 10k to arrive at a more accurate cost for building this site.
