Big news for developers out there: Google has just announced the release of a new, open sourced programming language called Go. The company says that Go is experimental, and that it combines the performance and security benefits associated with using a compiled language like C++ with the speed of a dynamic language like Python. Go’s official mascot is Gordon the gopher, seen here.

Here’s how Google describes Go in its blog post:

Go attempts to combine the development speed of working in a dynamic language like Python with the performance and safety of a compiled language like C or C++. In our experiments with Go to date, typical builds feel instantaneous; even large binaries compile in just a few seconds. And the compiled code runs close to the speed of C. Go is designed to let you move fast.

Whenever Rupert Murdoch goes back to his home country of Australia, he loosens up and says things to the press (usually his own outlets) that he might not say in the U.S. Of course, everyone in the U.S. picks up on it and it becomes a big story, as it did today after Murdoch told his own Sky News that he might start blocking Google and other search engines from giving searchers full access to articles on the Wall Street Journal’s website, WSJ.com. Asked whether he realized that Google was sending his news site a ton of traffic, Murdoch responded, “”We’d rather have fewer people coming to our Websites, but paying.”

If Murdoch wants fewer people coming to the WSJ.com and other news sites he controls, blocking Google from indexing those sites is the perfect way to achieve that goal. Just over 25 percent of the WSJ.com’s traffic comes directly from Google or Google news, according to estimates by Hitwise. About 12 percent of that comes from Google News, and another 15 percent from Google search directly.

When Google CEO Eric Schmidt mentioned a few weeks ago that the M&A spigot is now back on at the search giant, he wasn’t talking about a trickle. Today’s announced deal to by mobile ad startup AdMob for $750 million is Google’s largest acquisition since its $3.1 billion purchase of DoubleClick in March, 2008, and its third-largest ever after the $1.65 billion YouTube acquisition in 2006.

Why such a big bet? Because Google is gunning hard to dominate mobile Web advertising and AdMob has an early foothold in the display side. By focusing on the needs of mobile app developers, AdMob has “built what is approaching a $100 million business in three years,” says Jim Goetz, the partner at Sequoia Capital who sits on AdMob’s board, referring to the annualized revenue run-rate of the company. Since AdMob splits its revenues 60/40 with publishers, that implies AdMob is on course to see $40 million of that $100 million gross. The company is also cash-flow positive, with 140 employees.

Google has just announced that it has acquired AdMob, the mobile ad platform that has been especially popular on the iPhone, for $750 million. This is a big win for the company’s early investors, which include Sequoia Capital and Accel Partners (this is a huge day for Accel — they were also investors in Playfish, which was just acquired by EA. More recent investors include DFJ and Northgate Capital.

AdMob founder Omar Hamoui sent the following letter to customers:

Today we announced that AdMob has signed a definitive agreement to be acquired by Google for $750 million. We are extremely excited about this new partnership and what it means for our advertiser, developer and publisher partners.

AdMob’s people, products and tools will continue to work to deliver successful campaigns for you and to effectively monetize your mobile traffic – no interruptions. Our product and engineering teams will keep building great products for our customers. Our sales team will keep working with our thousands of advertisers to deliver successful campaigns. Our business development team will keep working to maximize ad revenue for the more than 15,000 mobile Web sites and applications that make up AdMob’s publisher network.

Last month Skype was in talks to acquire VoIP startup Gizmo5. It was a perfect backup plan in case all that IP litigation didn’t work out. – Gizmo5’s SIP infrastructure could theoretically replace Skype’s proprietary P2P back end.

After the Skype settlement, though, Gizmo5’s strategic value to Skype sort of plummeted. In the meantime, Google bought them, say multiple sources with knowledge of the deal, for around $30 million in cash. The deal is done, say our sources, and will be announced shortly.

Gizmo5 is a good fit with a number of Google products. Google Talk allows voice calls between users but has no PSTN link to allow incoming or outbound calls to real phones. Gizmo5 does this well already.

And Google Voice is a great VoIP and phone identity service, but they have no endpoint for calls. Gizmo5, which by the way already integrates with Google Voice, is a soft phone end point for Google phone users. In other words, you will be able to make and receive calls to your Google Voice phone number from your computer.

This looks to me like Gizmo5 will be the glue that puts Google Voice and Google Talk together into a single product. And that product looks a lot like a Skype competitor.

Yesterday I detailed my quest to find the throngs of Droid fans who had woken up at the crack of dawn to grab a place in line before Verizon unleashed the phone to the masses. Yet despite reports of lines elsewhere, I failed — the Verizon store in Palo Alto was a ghost town, as was the Best Buy down the street. Some commenters took my story and similar reports as an indication that the Droid’s launch had bombed, doomed to play out the same fate of the numerous supposed ‘iPhone killers’ before it. It looks like they may be wrong — that store sold over 70 Droids yesterday, according to one of its employees.

Today I returned to the Verizon store where yesterday’s quest began, looking to get my hands on one of the nifty docking stations that turns your Droid into a desktop clock/multimedia station. And while I expected a handful of other customers to be in the store, I was taken aback by just how crowded it was — each of the registers was busy ringing up a customer while others waited their turn, four people were standing in line just to touch the demo Droid unit, and I had to put my name on the list to talk to someone.

Last month, Apple rejected the Someecards iPhone app because it contained satirical comedy about public figures. After attempting to make their case and getting stonewalled, Someecards eventually gave into Apple and removed the offending cards which made fun of Hitler and Roman Polanski, among others. Apple swiftly approved the app and all was well.

Well, not exactly.

Apparently, Apple contacted Someecards a couple days ago because of some new content in the app — Someecards pushes new cards into the app just as it does on its site. There was one in particular that Apple did not find amusing, and wanted clarification on: A card making fun of President Obama Halloween costumes. It’s fairly easy to see why Apple wanted some clarification, the card involves race. Here’s what it says: “Just double-checking that your Obama costume will involve a mask and not shoe polish.”

Google’s Vice President of Search Product and User Experience Marissa Mayer was recently profiled in a Vogue Magazine article that offered a in-depth glimpse into the exec’s lifestyle, loves, career and fashion preferences. Now, Mayer has been named as one of Glamour Magazine’s 2009 Women of the Year. Joining Mayer on the list are a variety of female powerhouses and icons including Maya Angelou, First Lady Michelle Obama, Susan Rice, Euna Lee and Laura Ling.

Mayer has been frequently profiled in business and technology publications over the years, but it’s also nice to see her achievements highlighted in magazines like Vogue and Glamour. The brainy Stanford-grad has been able to set an example for young women everywhere. As one of Google’s early hires, she’s now helping to lead product design for one of the world’s most innovative companies. And she’s only 34. What’s not to love about a successful and geeky coder who also loves to wear Oscar de la Renta, Chanel and Armani?

Do you see something strange in this screenshot of Google’s homepage today? No, not Bert and Ernie (it’s Sesame Street’s 40th birthday). It’s that ad for the Verizon Droid right there under the search box (today is also Droid Day). Although, the juxtaposition does make it seem like Bert and Ernie are trying to get you to buy a Droid.

Google’s homepage is normally an ad-free zone. No more than 28 words are allowed on it, and Google is always trying to find ways to make it even sparer.

Over the past few weeks, it’s definitely been crunchtime as we’ve been putting together the panels and demos for our Realtime CrunchUp on November 20 in San Francisco. Get your tickets here. After much back and forth, and with the help of our Realtime Board, we finally have an agenda we are very excited to present (see below).

Speakers will include Twitter COO Dick Costolo, Salesforce CEO Marc Benioff, Facebook VP of Product Chris Cox, Foursquare CEO Dennis Crowley, angel investor Ron Conway, FriendFeed co-founders (and now-Facebook VPs) Paul Buchheit and Bret Taylor. The CrunchUp will take place at the Intercontinental Hotel in San Francisco and will kick off with a big roundtable discussion and one-on-one interviews, followed by startup demos and panel discussions drilling down into geo streams, media streams, marketing, and venture capital.

Google has just announced that it is open-sourcing a set of tools its own developers use to build some of the company’s most well known products, including Gmail, Google Docs, and Google Maps.

The first tool is called the Closure Compiler, which helps developers optimize their JavaScript code by removing extra portions of comments and code. The Compiler also has a sister program called Inspector — a plugin for Firebug that allows developers to view their optimized code in the browser, with all of their original variable names and other data restored (typically optimized code strips variable names and formatting that makes it very difficult to read). Google is also releasing the Compiler as a web app and a RESTful API.

The latest twist in the ongoing settlement talks between Google and book authors is that yesterday, the judge in the case denied an attempt by photographers to become part of the settlement. In the decision (embedded below), Judge Denny Chin basically ruled that photographers are not authors, and that the settlement only covers “word-based material,” with the exception of illustrations in children’s books.

The judge writes that the motion was filed too late, and that in any case, the current settlement does not preclude photographers from bringing their own lawsuit.

A source just tipped us on some interesting changes Google-owned YouTube has made that give its partners more control over the blocking of video content they upload to the service.

Basically, there are two new buttons in the interface for partners. One says ‘Block by Country’ and provides content partners with the ability to geo-block a single video rather than an entire account, an oft-requested feature that allows partners to restrict the geographical rights for specific videos. This can be helpful for blocking a clip in a region where it might be culturally offensive or where rights issues prevent an account for having distribution rights in a handful of countries.

The second button reads ‘Enable Auto Block outside Ownership’ (yes, that’s a confusing name). The purpose of the button is similar to the first button, but is for content owners who only have rights to a video in a single region. Using this feature they can quickly claim rights to that one region, while automatically blocking access everywhere else.

The more Google products you use, the more data it collects about everything you do online—your search history, your emails, the blogs and news sites you read, which videos you watch on YouTube, your news alerts, tasks ,and even shopping lists. For some of these, you need to explicitly grant Google permission to keep track of data associated with your profile. But it’s hard to keep up with everything Google is tracking.

So now the company is launching a Google Dashboard, which will give you a high-level summary of everything Google knows about you by virtue of the Google products you use. This might include how many emails are in your inbox, recent subject lines, which YouTube video you’ve watched lately (yes, all of them), appointments on your calendar, and more.

First, there was Google Voice. And all was good, and not so good. But it showed that there is a better way to manage voicemails than to listen to 15 in a row just to get to the one you care about.

Now, there is an alternative to Google Voice called Ribbit Mobile. And it too is very good. Ribbit Mobile is in private beta, but the first 500 people to sign up with the invite code “techcrunch” will jump to the front of the line.

Searching retail sites can be frustrating at times. While many retailers try to present product search in a visually appealing way, search can often be slow or difficult to refine. Tonight, Google is making a huge play in retail space with the launch of Commerce Search, a hosted enterprise search product to power online retail stores and e-commerce websites.

Google offers a general hosted search product that is used by organizations that want to add customized Google search functionality to their websites. Google is now entering the vertical space, by the first tailor-made enterprise product, with retail optimized space. There are four key components to thew new search offering for retailers:

Google News has just launched a pretty cool new feature: Create your own news section. As you can probably guess, this allows you to create a new area of your Google News personalized page (you have to be signed-in) for anything you want. You simply fill-out a section title, put in any search terms you want it to look for, select a country, and you’re set.

Previously, you could make customized sections for Google News, but it was limited to single queries about topics. With multiple queries, this is much more comprehensive. And the pages look a lot nicer with images automatically pulled in. You can also now filter by source locations, restricting items to a single country or even state.

A battle has been brewing for months now: Google and Facebook both want to be the social layer that sits on top of every site on the Internet. So far, at least in mindshare, Facebook has been winning this battle with Facebook Connect. Google’s offering, Friend Connect, is the sibling that gets no respect. But that could change starting today with some new features and functionality.

There are actually a number of new or tweaked features in Friend Connect, but the overall gist of the changes is that they will allow site owners to offer a more personalized social experience to their visitors, while making it easier for visitors to connect with each other. “Normally we do one feature at a time, but this is a set of features,” Friend Connect product manager Mussie Shore tells us, noting that this is a special launch to his team.

In this political season, why not talk about the roughest political argument of them all: the real meaning of Apple’s announcement of over 100,000 apps in the app store. Are these apps important because, as Steve Ballmer says, the iPhone doesn’t handle the Internet well? Are these apps a testament to a strong ecosystem? Or are these apps a testament to Apple’s marketing might and the perception that you just might make your millions by selling flashlight app for the Touch.

The announcement, which basically says that there are over 100,000 applications available for the iPhone and iPod Touch with some of the true winners – Smule’s I Am T-Pain, for example – getting 10,000 or more downloads a day.

I haven’t noticed this myself today, but it appears at least a subset of Gmail users are inadvertently drawing closer to an inbox with zero unread e-mails thanks to a nasty bug that marks messages as read even before the user opens them.

Former TechCrunch writer Ouriel Ohayon was one of the first to signal the bug on Twitter – with many of his followers echoing the phenomenon – and a quick search shows other users are seeing the same thing.
