HasOffers, a startup that helps mobile app developers see which ad efforts are actually paying off, is announcing that it has raised a $9.4 million round of funding led by Accel Partners.

The company was founded in 2009 — the product that it initially built, and the one that’s still highlighted on the HasOffers website, is a system that helps ad networks and agencies manage their performance-based programs. (Those agencies and ad networks include Bucksense, Tapjoy, and Sponsorpay.)

However, CEO Peter Hamilton said the team realized that mobile advertisers were facing a similar problem, so it built a product called MobileAppTracking, allowing developers to see where app installs, engagement, and purchases actually come from. So as publishers run ad campaigns, they can see which social networks, publishers, and ad networks are giving them the best results, and they can adjust their efforts accordingly.

Samsung showed off its Wallet app to developers earlier this year, and now Korean customers can download it onto compatible Android devices from the company's own app market. Currently it only appears to collect credit card info, which customers can then use to pay for goods and services at online merchants, verified by a one-time password or PIN. Clearly aimed at both Google Wallet and Apple's Passbook, Samsung plans to add a few features we've seen in Passbook that will make tickets, membership cards and coupons accessible all in one place. According to the translated press release it's out for the Galaxy S 4, Galaxy S III, Galaxy Note, Galaxy Note II, Galaxy Note 10.1, Galaxy S II HD LTE, although whether it will be featured in a Gangnam Style 2 video remains unknown.

Update: Commenter Chris posted a pic showing that the app is also live in the US Samsung Apps market, although it looks a bit different and lists more of the Passbook features we were expecting. This may be explained by a post on the Samsung Wallet Partners site, indicating it launched in open beta on the 18th, with support for transportation tickets, membership cards, coupons and event tickets. We checked and it's not showing up on our Note IIs or GS4s yet, but if you have one it may be worth taking a peek at Samsung's app store to see what's waiting inside.

After the hacking collective Anonymous launched a Twitter campaign pledging to go after the Guantanamo Bay Naval Base in Cuba, the U.S. military barred all Wi-Fi access on the base, according to the Associated Press. All social media, including Facebook and Twitter, also has been banned.

Army Lt. Col. Samuel House told the Associated Press that the shuttering of the base's Wi-Fi was because of Anonymous' public plans to "disrupt activities" at the military prison.

While no disruptions have yet been reported, according to the Associated Press, Anonymous has promised to make good on its threats.

Olympia Circuits is best known for its Arno board and Arno Shield, which are designed to ease the Arduino learning curve by providing a bevy of pre-wired sensors and controls along with detailed instructions for several DIY projects. The company announced a couple of new products at Maker Faire this past weekend: the Arno Digital RGB Add-On and the SODA HE-1.0 Arduino datalogger. With the former, your Arno simply gains three RGB LEDs, while the latter stands for "Simple, Open Data Acquisition, High Efficiency." It's an Arduino board with screw terminals designed around Atmel's ATmega32u4 that features a real-time clock (RTC) with battery backup, a high-precision ADC and a microSD card slot. The RTC can either wake the entire board or trigger an interrupt at set intervals, which makes the board very power efficient when used in the field. Olympia Circuits will be updating its website with more info shortly (including availability and pricing). Until then, don't miss our hands-on gallery below.

Coming months after the feature's introduction on Android and PCs, Vudu has updated the iOS version of its app with the ability to download movies for viewing offline. Unlike the Android version, this feature is not restricted to tablets however, with downloads of your Vudu / Ultraviolet collection on iPads and iPhones. Other tweaks include making the Player "easier to use" and adding closed captions on iPhone. The Flixster app already allowed for Ultraviolet movie downloads on iOS, however Vudu has access to some movies that may not be available there. The updated version of the free app is available on on iTunes, although you will need an associated account (with updated password info) with unlocked videos to get any use out of it.
