Introduction: G'day, I noticed the default sort order for the forum is to show the posts with the most replies first. That seems a bit odd for a forum. Would it not make sense to show the posts with the most recently replies first? It is possible to re-sort the forum threads that way by clicking on the "Last post" header (twice). It would seem like a more sensible default. I've checked and I see the same behaviour as both a registered (logged in) and anonymous user. Cheers - Callum .
3 0.1209169 248 high scalability-2008-02-13-What's your scalability plan?
Introduction: How do you plan to scale your system as you reach predictable milestones? This topic came up in another venue and it reminded me about a great comment an Anonymous wrote a while ago and I wanted to make sure that comment didn't get lost. The Anonymous scaling plan was relatively simple and direct: My two cents on what I'm using to start a website from scratch using a single server for now. Later, I'll scale out horizontally when the need arises. Phase 1 Single Server, Dual Quad-Core 2.66, 8gb RAM, 500gb Disk Raid 10 OS: Fedora 8. You could go with pretty much any Linux though. I like Fedora 8 best for servers. Proxy Cache: Varnish - it is way faster than Squid per my own benchmarks. Squid chokes bigtime. Web Server: Lighttpd - faster than Apache 2 and easier to configure for me. Object Cache: Memcached. Very scalable. PHP Cache: APC. Easy to configure and seems to work fine. Language: PHP 5 - no bloated frameworks, waste of time for me. You spend too mu

Introduction: You may have noticed something is a little a different when visiting HighScalability today: We've Moved! HighScalability.com has switched hosting services to Squarespace.com. House warming gifts are completely unnecessary. Thanks for the thought though. It's been a long long long process. Importing a largish Drupal site to Wordpress and then into Squarespace is a bit like dental work without the happy juice, but the results are worth it. While the site is missing a few features I think it looks nicer, feels faster, and I'm betting it will be more scalable and more reliable. All good things. I'll explain more about the move later in this post, but there's some admistrivia that needs to be handled to make the move complete: If you have a user account and have posted on HighScalability before then you have a user account, but since I don't know your passwords I had to make new passwords up for you. So please contact me and I'll give you your password so you can login and change it.

Introduction: With over 15 billion page views a month Tumblr has become an insanely popular blogging platform. Users may like Tumblr for its simplicity, its beauty, its strong focus on user experience, or its friendly and engaged community, but like it they do.Growing at over 30% a month has not been without challenges. Some reliability problems among them. It helps to realize that Tumblr operates at surprisingly huge scales: 500 million page views a day, a peak rate of ~40k requests per second, ~3TB of new data to store a day, all running on 1000+ servers.One of the common patterns across successful startups is the perilous chasm crossing from startup to wildly successful startup. Finding people, evolving infrastructures, servicing old infrastructures, while handling huge month over month increases in traffic, all with only four engineers, means you have to make difficult choices about what to work on. This was Tumblr's situation. Now with twenty engineers there's enough energy to work on issues an

You be the judge.Just what is Yahoo buying? The business acumen of the deal is not something I can judge, but if you are doing due diligence on the technology then Tumblr would probably get a big thumbs up.

Introduction: Chris Dixon unearthed a great quote from Douglas Adams on the nature of technological adoption that unsurprisingly hits the mark in our ever changing and evolving world: Anything that is in the world when you’re born is normal and ordinary and is just a natural part of the way the world works. Anything that’s invented between when you’re fifteen and thirty-five is new and exciting and revolutionary and you can probably get a career in it. Anything invented after you’re thirty-five is against the natural order of things Some that come to mind: horse to car, index card to online search, PC to mobile, web to app, portal to messaging, Newton to Einstein, oil to electric, rock to rap, Aquinas to Bacon, buying to renting, files to streaming, network TV to cordkilling, broadcast to social, programming CPUs to programming biology, server to cloud, vm to container, wired to wireless, long read to TLDR, privacy to public to ephemeral, paper based news aggregation to digital a
