We Need to Stop Google’s Exploitation of Open Communities. Mikel Maron from OpenStreetMap is justifiably angry about Google MapMaker, which copies OpenStreetMap’s model of crowdsourcing geographic data (even copying the OSM idea of Mapping Parties) but keeps the data under a much more restrictive license, and uses the Google brand to market itself to African governments.
Why Facebook open-sourced its datacenters. Jon Stokes speculates that Facebook plan to use open source hardware to compete with Google at datacenter efficiency . This isn’t a new pattern. Years ago when I worked at Yahoo! I was furiously jealous of the secret sauce technologies that allowed Google to build big applications faster than anyone else, such as BigTable and map/reduce. Today, the open source world has created better, free alternatives—sponsored in part by Facebook, Yahoo! and other Google competitors.
Is a relational database with many-to-many relationships difficult to develop into a web app?
Many to Many tables can be a bit of a pain to deal with using regular SQL, but a good ORM can abstract away any potential complexity almost entirely. I find using the Django ORM means I’m much less likely to shy away from a design that involves a many-to-many relationship because I know it won’t increase the complexity of the application. I imagine the Rails ORM has the same effect.
[... 91 words]Google APIs & Developer Products. Presented as a sort-of-periodic table. There’s quite a bit of stuff on here I didn’t know about.
Getting Started—Google URL Shortener API. The API for the goo.gl URL shortener is really nice—no API key required, easy to create a short URL and you can retrieve detailed stats breakdowns (similar to bit.ly) as JSON for any URL.

Why did Google Wave fail to get significant user adoption?
When Wave first launched, individual Waves didn’t have a URL. This made it impossible to link to them from outside of Wave—people were having to say “log in to Wave, then search for X”. If you can’t link to something on the internet, it may as well not exist.
[... 67 words]Google and Microsoft Cheat on Slow-Start. Should You? Fascinating optimisation tricks by some of the big websites, which violate the RFC governing the TCP slow-start algorithm in order to perform better in the common case.
Is it not time for Google to redesign its search page by removing the “search” & “I’m Feeling Lucky” buttons since the buttons are now useless with the new “Instant” structure?
I don’t think so. The “Search” button defines their entire purpose. The “I’m Feeling Lucky” button is an important part of their brand.
[... 60 words]“Last I heard Google’s search index was sharded by document rather than by term.”. Fascinating comment by jasonwatkinspdx on Hacker News.
Closure Compiler Service (via) A hosted version of the Google Closure Compiler (JavaScript minifier) running on App Engine. It has both a user interface and a REST API, which means you can use it as part of an automated build process without needing to set up a local copy of the software.
App Engine at Google I/O 2010. OpenID and OAuth are now baked in to the AppEngine users API. They’re also demoing two very exciting new features—a mapper API for doing map/reduce style queries against the data store, and a Channel API for building comet applications.
Google Font Directory: Font Preview. Handy tool for trying out the 18 open source fonts Google have released, along with server-side browser sniffing technology that serves up the correct version (including for IE6). The browser sniffing makes me a bit uncomfortable—will it play well with intermediate caches? What happens if I save a local copy of a page and then open it up in a different browser?
Stack Overflow Blog: OpenID, One Year Later. Google’s support is a huge deal—61% of Stack Overflow accounts use Google. Google’s implementation of directed identity has caused problems though, since Google provide a different OpenID for each domain making it hard for Stack Overflow, Server Fault and Super User to correlate accounts. Their solution is to require a (verified) e-mail address from Google OpenID users using sreg and use that as a key for the accounts.
Why Google MapMaker is not Open. Non-commercial use only, strict attribution requirements and you aren’t allowed to use the data for services that might compete with Google. This is why I’m disappointed every time I see Google encouraging people to contribute to Map Make, especially in the developing world—if those people contributed to OpenStreetMap instead they would be building something far more valuable for their community.
RE2: a principled approach to regular expression matching. Google have open sourced RE2, the C++ regular expression library they developed for Google Code Search, Sawzall, Bigtable and other internal projects. Unlike PCRE it avoids the potential for exponential run time and unbounded stack usage and guarantees that searches complete in linear time, mainly by dropping support for back references.
Google Image Charts: Mathematical (TeX) Formulas (via) I’m not sure when they added this, but you can now use the Google Charts Image API to render mathematical formulas, specified using TeX syntax. Wordpress.com and Wikipedia have both offered this feature for quite a while, but now you can use it anywhere on the Web.
WARNING: Google Buzz Has A Huge Privacy Flaw. Interesting one this: by default, Buzz creates a public profile for you that lists the people you follow—but your default set of followers is derived from the people you contact most frequently using Gmail. This means users of Buzz may inadvertently reveal their most frequent contacts, which is an issue for people like journalists with anonymous sources, unhappy employees seeking new work or even people having e-mail based affairs.
Fixing the Google Account problem. 3,000+ words explaining how to open a Google Doc invitation sent to an e-mail address that isn’t associated with your Google account. Worth reading just to get an idea for the enormous complexity involved in running a large scale identity system and designing an interface for managing aliases and multiple profiles. Google haven’t got it right yet—has anyone else?

HTTP + Politics = ? Mark Nottingham ponders the technical implications of Australia’s decision to apply a filter to all internet traffic. Australia is large enough (and far enough away from the northern hemisphere) that the speed of light is a performance issue, but filtering technologies play extremely poorly with optimisation technologies such as HTTP pipelining and Google’s SPDY proposal.
Recently Google Translate announced the ability to hear translations into English spoken via text-to-speech (TTS). Looking at the Firebug Net panel for where this TTS data was coming from, I saw that the speech audio is in MP3 format and is queried via a simple HTTP GET (REST) request: http://translate.google.com/translate_tts?q=text
A piece with a lot of screenshots about the close tab behaviour in Google Chrome. If you click “close” with your mouse, Chrome doesn’t resize the remaining tabs until you mouse away from the area. This means you can click “close” multiple times without having to chase the close button. I hadn’t noticed this, partly because Chrome doesn’t do it if you hit Command-W. They even switch the position of the close button in RTL languages such as Arabic.
Any sufficiently advanced damage control is indistinguishable from ethics.

EtherPad is Back Online Until Open Sourced. Fantastic news. EtherPad just got acquired by Google and announced the team would be joining the Google Wave effort and the existing service would be shut down. Lots of people complained, so they’re going to keep it alive until they’ve open sourced the code!
Google Analytics goes async. This is excellent news—the latest version of the Google Analytics JavaScript is designed to allow for asynchronous loading, so it won’t hold up the rendering of your page. Analytics and banner ads are the two worst offenders when it comes to slowing down page loads. Now if only a banner ad vendor would follow suit...
Negative Cashback from Bing Cashback (via) Some online stores show you a higher price if you click through from Bing—and set a cookie that continues to show you the higher price for the next three months. It’s unclear if this is Bing’s fault—comments on Hacker News report that Google Shopping sometimes suffers from the same problem (POST UPDATED: I originally blamed Bing for this).
Chromium OS User Experience. The 2 minute UI concept video is probably the best way to understand the ideas behind Google’s Chrome OS.
SPDY: The Web, Only Faster. Alex Russell explains the benefits of Google’s SPDF proposal (a protocol that upgrades HTTP)—including header compression, multiplexing, the ability to send additional resources such as images and stylesheets down without needing the data:uri hack and Comet support built in to the core assumptions of the protocol.
Awkward Suggestions (via) The Google search box “suggest” feature returns very different results depending on the quality of your grammar—“how 2” v.s. “how might one” is particularly illuminating.
The Go Programming Language. A brand new systems programming language, designed by Robert Griesemer and Unix/Plan 9 veterans Rob Pike and Ken Thompson and funded by Google. Concurrency is supported by lightweight communicating processes called goroutines. “It feels like a dynamic language but has the speed and safety of a static language.”
It’s interesting to me how much [Closure] feels like a more advanced version of Dojo in many ways. There's a familiar package system, the widgets are significantly more mature, and Julie and Ojan's Editor component rocks. The APIs will feel familiar (if verbose) to Dojo users, the class hierarchies seem natural, and Closure even uses Acme, the Dojo CSS selector engine.
