If you have a hard time passing the subject you and sometimes you'll be too distracted by everything else in school, what do you think is the best thing to do? I really know what it feels like when your grade is not really satisfactory or does not meet your expectations. I was once a student of my own and I know how the flow. You have so many everyday subjects and teachers will continue to remove information that your brain can't handle all at the same time. You know what really help me? The opinion of a teacher to help me understand my lessons carefully. It is a very ideal indeed and I'm glad we know have web sites that offer some of the services a great online tutorials as bigfoottutors though I don't need it right now because I no longer learn but I don't mind letting my children get the services for the benefit of their own. "Transforming students by way of Measurable", that's exactly what the tutor Bigfoot aims to provide their students. When checking their site, I find some of the services and offers that they currently offer and I am sure will grab this opportunity. To provide you with a brief Guide on their website, let me list the benefits you get through the online tutorial Service (Bigfoot tutor in particular).

CAPTCHAs that capture your heart

Notice something different about reCAPTCHA today? You guessed it; those tricky puzzles are now warm and fuzzy just in time for Valentine’s Day. Today across the U.S., we're sharing CAPTCHAs that spread the message of love.

Some examples of Valentine's Day CAPTCHAs

But wait. These look really easy. Does this mean that those pesky bots are going to crack these easy CAPTCHAs and abuse our favorite websites? Not so fast.

A few months ago, we announced an improved version of reCAPTCHA that uses advanced risk analysis techniques to distinguish humans from machines. This enabled us to relax the text distortions and show our users CAPTCHAs that adapt to their risk profiles. In other words, with a high likelihood, our valid human users would see CAPTCHAs that they would find easy to solve. Abusive traffic, on the other hand, would get CAPTCHAs designed to stop them in their tracks. It is this same technology that enables us to show these Valentine’s Day CAPTCHAs today without reducing their anti-abuse effectiveness.

But that’s not all. Over the last few months, we’ve been working hard to improve the audio CAPTCHA experience. Our adaptive CAPTCHA technology has, in many cases, allowed us to relax audio distortions and serve significantly easier audio CAPTCHAs. We’ve served over 10 million easy audio CAPTCHAs to users worldwide over the last few weeks and have seen great success rates. We hope to continue enhancing our accessibility option in reCAPTCHA in the months to come. Take a listen to this sample of easy audio CAPTCHA:


We’re working hard to improve people’s experience with reCAPTCHA without compromising on the spam and abuse protection you’ve come to trust from us. For today, we hope you enjoy our Valentine’s Day gift to you.

Security Reward Programs Update

From investing our time in doing security research to paying for security bugs and patches, we've really enjoyed and benefited from our involvement with the security community over the past few years. To underscore our commitment, we want to announce yet another increase in payments since we started our reward programs.

Starting today, we will broaden the scope of our vulnerability reward program to also include all Chrome apps and extensions developed and branded as "by Google." We think developing Chrome extensions securely is relatively easy (given our security guidelines are followed), but given that extensions like Hangouts and GMail are widely used, we want to make sure efforts to keep them secure are rewarded accordingly.

The rewards for each vulnerability will range from the usual $500 up to $10,000 USD and will depend on the permissions and the data each extension handles. If you find a vulnerability in any Google-developed Chrome Extensions, please contact us at goo.gl/vulnz.

In addition, we decided to substantially increase the reward amounts offered by our Patch Reward Program. The program encourages and honors proactive security improvements made to a range of open-source projects that are critical to the health of the Internet in recognition of the painstaking work that's necessary to make a project resilient to attacks.

Our new reward structure is:
  • $10,000 for complicated, high-impact improvements that almost certainly prevent major vulnerabilities in the affected code. 
  • $5,000 for moderately complex patches that provide convincing security benefits.
  • Between $500 and $1,337 for submissions that are very simple or that offer only fairly speculative gains. 
We look forward to ongoing collaboration with the broader security community, and we'll continue to invest in these programs to help make the Internet a safer place for everyone.

Keeping YouTube Views Authentic


YouTube isn’t just a place for videos, it’s a place for meaningful human interaction. Whether it’s views, likes, or comments, these interactions both represent and inform how creators connect with their audience. That’s why we take the accuracy of these interactions very seriously. When some bad actors try to game the system by artificially inflating view counts, they’re not just misleading fans about the popularity of a video, they’re undermining one of YouTube’s most important and unique qualities.

As part of our long-standing effort to keep YouTube authentic and full of meaningful interactions, we’ve begun periodically auditing the views a video has received. While in the past we would scan views for spam immediately after they occurred, starting today we will periodically validate the video’s view count, removing fraudulent views as new evidence comes to light. We don’t expect this approach to affect more than a minuscule fraction of videos on YouTube, but we believe it’s crucial to improving the accuracy of view counts and maintaining the trust of our fans and creators.

As YouTube creators, we ask you to be extra careful when working with third-party marketing firms; unfortunately some of them will sell you fake views. If you need help promoting your video, please review our posts about working with third party view service providers and increasing YouTube views.

FFmpeg and a thousand fixes

At Google, security is a top priority - not only for our own products, but across the entire Internet. That’s why members of the Google Security Team and other Googlers frequently perform audits of software and report the resulting findings to the respective vendors or maintainers, as shown in the official “Vulnerabilities - Application Security” list. We also try to employ the extensive computing power of our data centers in order to solve some of the security challenges by performing large-scale automated testing, commonly known as fuzzing.

One internal fuzzing effort we have been running continuously for the past two years is the testing process of FFmpeg, a large cross-platform solution to record, convert and stream audio and video written in C. It is used in multiple applications and software libraries such as Google Chrome, MPlayer, VLC or xine. We started relatively small by making use of trivial mutation algorithms, some 500 cores and input media samples gathered from readily available sources such as the samples.mplayerhq.hu sample base and FFmpeg FATE regression testing suite. Later on, we grew to more complex and effective mutation methods, 2000 cores and an input corpus supported by sample files improving the overall code coverage.

Following more than two years of work, we are happy to announce that the FFmpeg project has incorporated more than a thousand fixes to bugs (including some security issues) that we have discovered in the project so far:

$ git log | grep Jurczyk | grep -c Coldwind

This event clearly marks an important milestone in our ongoing fuzzing effort.

FFmpeg robustness and security has clearly improved over time. When we started the fuzzing process and had initial results, we contacted the project maintainer - Michael Niedermayer - who submitted the first fix on the 24th of January, 2012 (see commit c77be3a35a0160d6af88056b0899f120f2eef38e). Since then, we have carried out several dozen fuzzing iterations (each typically resulting in less crashes than the previous ones) over the last two years, identifying bugs of a number of different classes:
  • NULL pointer dereferences, 
  • Invalid pointer arithmetic leading to SIGSEGV due to unmapped memory access, 
  • Out-of-bounds reads and writes to stack, heap and static-based arrays, 
  • Invalid free() calls, 
  • Double free() calls over the same pointer, 
  • Division errors, 
  • Assertion failures, 
  • Use of uninitialized memory. 
We have simultaneously worked with the developers of Libav, an independent fork of FFmpeg, in order to have both projects represent an equal, high level of robustness and security posture. Today, Libav is at 413 fixes and the library is slowly but surely catching up with FFmpeg.

We are continuously improving our corpus and fuzzing methods and will continue to work with both FFmpeg and Libav to ensure the highest quality of the software as used by millions of users behind multiple media players. Until we can declare both projects "fuzz clean" we recommend that people refrain from using either of the two projects to process untrusted media files. You can also use privilege separation on your PC or production environment when absolutely required.

Of course, we would not be able to do this without the hard work of all the developers involved in the fixing process. If you are interested in the effort, please keep an eye on the master branches for commits marked as "Found by Mateusz "j00ru" Jurczyk and Gynvael Coldwind" and watch out for new stable versions of the software packages.
