(Phys.org)—A team of researchers with affiliations to institutions in Belgium, the U.K. and The Netherlands has found that orangutans use hand placement around their mouths to make their voices deeper, perhaps attempting to seem as if they are bigger to threats. In their paper published in The Journal of Experimental Biology, the researchers explain their study and why they believe their results might offer clues about the development of language in a species. More information: Acoustic models of orangutan hand-assisted alarm calls, The Journal of Experimental Biology, jeb.biologists.org/content/218/6/907 The team had faithfully recreated the biological mechanism used by the apes and showed that the technique they used could indeed by viewed as a means of modifying communication on purpose to cause a desired outcome. Using their hands to change how they sound to threats, the team suggests, is perhaps a form of a precursor to more advanced communications skills, if that is, they are not doing it by accident.

Biologists studying orangutans have noticed before that the apes sometimes cup their hands around their mouths when making kissing noises. While some may have assumed the gesture was friendly, later research showed it was a means by which the apes were warning others of the presence of something threatening, such as human beings. In this new effort, the researchers tested the idea that cupping the hands around the mouth made the animal seem more impressive, perhaps, to deter those presenting threats from coming closer.To learn more, the researchers used mathematical modeling to help them create a real world physical model of the vocal parts used by an orangutan to create its kissing noises and then to model the impact of using hands to modify the sound that came out. Recording analysis was used to determine the sound processing that was taking place and the impact it had on tone. The team found that cupping of the hands served to extend or elongate the path traveled by the sound (as occurs with musical instruments) and thus caused it to come out sounding lower. They also found that their model showed it was possible to create the right overtones, a key component of sound made by larger animals. They then used sound editing equipment to remove extraneous noise from recordings of orangutans in the wild making their kissing noises and compared them to their models—doing so showed a match. last_img read more

Rahul pushes for increasing partys base

first_imgAt the brain-storming meeting of the Election Authority of the party, Gandhi is learnt to have expressed his concern over the tardy pace of organizational polls and asked young AICC secretaries to take responsibility to ensure that it gets the needed momentum in states.Re-introducing active membership concept, common membership across all the wings of Congress and enhanching the representation ratio of SCs, STs, OBCs and minorities in Committees are some of the measures that were debated threadbare during the meeting in which Gandhi was present for one and half hour.

Did Facebook just have another security scare

first_imgFacebook’s public image suffered quite a few setbacks in recent times. The Cambridge analytica scandal has opened up a pandora’s box full of questions about user data security and privacy. In the recent senate hearings, Facebook CEO, Mark Zuckerberg had an apologetic tone and he promised to give utmost importance to user data security. The misfortunes however, doesn’t seem to be over for Zuckerberg and Facebook. In a latest security scare, a bug had caused quite a ruckus for the tech giant. Facebook composer bug Now let’s talk about the bugs, yes, you read that correctly, there were more than one recent Facebook bugs affecting user data and privacy. The first bug was related to the Facebook message composer. According to Facebook’s Chief Privacy Officer Erin Egan, the bug affected composer’s privacy settings in a way that when the users were creating new posts, it automatically changed the privacy settings to public. This meant that user updates which might have been private, were available publicly. This bug had affected 14 million users worldwide and it was active during 18th May to 22nd May 2018. It took Facebook till 27th May to identify the bug and then rectify the problem. As a trust building measure, Facebook had sent notifications to all the users affected by this breach. A snapshot of the Facebook notification looked like this: Source: Techcrunch Automatic Unblocking bug The second incident occurred was between 29th May to 5th June. This particular incident was reported via a Facebook blog post which stated that a bug that had affected around 800k Facebook users, had temporarily unblocked contacts and enabled previously blocked contacts to message or view the details of the respective users. This security breach was in a way potentially dangerous since it openly allowed stalking or even harassment. Facebook had although stated that this bug had unblocked one contact per user. The official Facebook notification to the affected users looked like this: Source: Facebook Blog Facebook Analytics Data leak The story of bugs is not over yet. There were recent reports that the Facebook analytics data of around 3 percent Facebook apps were leaked to testers accidentally. This was  due to a faulty automated email system according to Facebook. Although Facebook insists on the fact that no personal user data was leaked, still this incident doesn’t go down well keeping in mind the company’s latest record of user privacy and data secrecy. Facebook is trying to be transparent in its approach to tackle this menace of recurring bugs, but how successful their efforts will be, only time and their future actions will tell.

GitLab 117 releases with multilevel child epics API integration with Kubernetes search

first_imgYesterday, the team at Gitlab released GitLab 11.7, an application for the DevOps lifecycle that helps the developer teams work together efficiently to secure their code. GitLab 11.7 comes with features like multi-level child epics, API integration with Kubernetes, cross-project pipeline and more. What’s new in GitLab 11.7 Managing releases with GitLab 11.7 This version of GitLab eliminates the need for manual collection of source code, build output, or metadata associated with a released version of the source code. GitLab 11.7 comes with releases in GitLab Core which helps users to have release snapshots that include the source code and related artifacts. Multi-level child epics for work breakdown structures This release comes with multi-level child epics in GitLab portfolio management which allow users to create multi-level work breakdown structures. It also helps in managing complex projects and work plans. This structure builds a direct connection between planning and actionable issues. Users can now have an epic containing both issues and epics. Streamlining JavaScript development with NPM registries This release also delivers NPM registries in GitLab Premium that provides a standard and secure way to share and version control NPM packages across projects. Users can then share a package-naming convention for utilizing libraries in any Node.js project and NPM. Remediating vulnerabilities GitLab 11.7 helps users to remediate vulnerabilities in the apps and suggest a solution for Node.js projects managed with Yarn. Users can download a patch file, and apply it to their repo using the git apply command. They can then push changes back to their repository and the security dashboard will then confirm if the vulnerability is gone. This process is easy and reduces the time required to deploy a solution. API integration with Kubernetes This release comes with API support to Kubernetes integration. All the actions that are available in the GUI currently, such as listing, adding, and deleting a Kubernetes cluster are now accessible with the help of the API. Developers can use this feature to fold in cluster creation as part of their workflow. Cross-project pipeline With this release, it is now possible to expand upstream or downstream cross-project pipelines from the pipeline view. Users can view the pipelines across projects. Search filter box for issue board navigation This release comes with a search filter that makes navigation much easier. Users can simply type a few characters in the search filter box to narrow down to the issue board they are interested in. Project list redesign Project list UI is redesigned in GitLab 11.7 and mainly focuses on readability and summary of the project’s activity. Import issues CSV This release makes transitions easier. Users can now import issues into GitLab while managing their existing work. This feature works with Jira or any other issue tracking system that can generate a CSV export. Support catch-all email mailboxes This release supports sub-addressing and catch-all email mailboxes with a new email format that allows more email servers to be used with GitLab, including Microsoft Exchange and Google Groups. Include CI/CD files from other projects and templates With this release, users can now include their snippets of configuration from other projects and predefined templates. This release also includes snippets for specific jobs, like sast or dependency_scanning, so users can use them instead of copying and pasting the current definition. GitLab Runner 11.7 The team at GitLab also released GitLab Runner 11.7 yesterday. It is an open source project that is used to run CI/CD jobs and send the results back to GitLab. Major improvements In GitLab 11.7, the performance of viewing merge requests has been improved by caching syntax highlighted discussion diffs. Push performance has been improved by skipping pre-commit validations that have passed on other branches. Redundant counts in snippets search have been removed. This release comes with Mattermost 5.6, an open source Slack-alternative that includes interactive message dialogs, new admin tools, Ukrainian language support, etc. Users are generally happy with GitLab 11.7 release. One of the users who has been using GitLab for quite some time now is waiting for MR[0]. They commented on Hacker News, “I’m impatiently waiting for this MR [0] that will allow dependant containers to also talk to each other. It’s the last missing piece for my ideal CI setup.” To which, GitLab’s product manager for Verify (CI) replied, “Thanks for bringing this up I hadn’t seen your contribution! I think this is a great idea. I know the technical team has been overwhelmed with community contributions as of late – which is a good problem to have but one that we’re still solving. I’m going to try and shepherd this one along myself.” Some users think if GitLab can pull off the npm registry well, then this might prove to be the beginning of a universal package management server built into Gitlab. One of the comments reads, “Gitlab API is amazingly simple and flexible, can be used efficiently from the terminal to list CI jobs, your issues, edit them.” Users are also comparing GitLab with GitHub, where some users are supporting GitHub. One user commented, “GitLab’s current homepage hides their actual site (the repositories) and makes it hard as a developer to actually get started compared to Github.” Another user commented, “We’ve started using Gitlab where I work and it’s so much better than GitHub.” Users are also facing issues with memory optimization. One of the comments reads, “I like GitLab but noticed my Docker container running it is steadily requiring more memory to run smoothly. It’s sitting at 12GB right now, which is a little too high for my taste. I wish there were ways to reduce this.” Read Next Introducing GitLab Serverless to deploy cloud-agnostic serverless functions and applications GitLab 11.5 released with group security and operations-focused dashboard, control access to GitLab pages GitLab 11.4 is here with merge request reviews and many more featureslast_img read more

GDPR complaint claims Google and IAB leaked highly intimate data of web

first_imgLast September, a complaint was filed against Google and other ad auction companies about a data breach that “affects virtually every user on the web”. This complaint was made by a host of privacy activists and browser makers, alleging that tech companies broadcasted people’s personal data to dozens of companies, without proper security through a mechanism of “behavioural ads”. The complaint stated that every time a person visits a website and is shown a “behavioural” ad on a website; intimate personal data describing each visitor and what they are watching online is captured and broadcast to tens or hundreds of companies. This was done in order to request potential advertisers’ bids for the attention of the specific individual visiting the website. The complaints were lodged by Jim Killock of the U.K.’s Open Rights Group, tech policy researcher Michael Veale of University College London, and Johnny Ryan of the pro-privacy browser firm Brave. They claimed that Google and other ad-tech firms were breaking the EU’s strict General Data Protection Regulation (GDPR) by unlawfully recording people’s sensitive characteristics. Now, new evidence has been released by the very same organizations that filed last September’s complaint, showing the data broadcasted includes information about people’s ethnicity, disabilities, sexual orientation and more. This sensitive information allows advertisers to specifically target incest, abuse victims, or those with eating disorders. The irony of it being, yesterday was ‘International Data Protection Day”. What is Behavioral advertising? Yahoo finance has explained the concept of behavioral advertising very simply. The online ad industry tracks a person’s movements around the internet and builds a profile based on what the individual looks at/ sites the user visits. On visiting a webpage that runs behavioral ads, an automated auction takes place between ad agencies with the winner allowed being to show the user an ad that supposedly matches their profile. This ultimately means that for the real-time bidding system to work, personal details of the users have to be broadcasted to the advertisers in so-called “bid requests”. Evidence against Google and IAB Joining the list of complainants is Poland’s Panoptykon Foundation, another rights group, that has complained to its local data protection authority about organizations including Google and the Interactive Advertising Bureau (IAB), which is the industry body that sets the rules for ad auctions. The evidence submitted by the complainants comprises category lists from Google and IAB, including topics such as being an incest victim, having cancer, having a substance-abuse problem, being into a certain kind of politics or adhering to a certain religion or sect. Special needs kids, endocrine and metabolic diseases, birth control, infertility, diabetes, Islam, Judaism, disabled sports, bankruptcy- these serve as supplementary evidence for the two original complaints filed with the UK’s ICO and the Irish DPC last year. A Google spokesperson told TechCrunch that the company has “strict policies that prohibit advertisers on our platforms from targeting individuals on the basis of sensitive categories” and that if they did find such ads violating said policies, they would take immediate action”. The original IAB lists can be downloaded as a spreadsheet. The PDF versions of the IAB lists with special category and sensitive data highlighted by the complainants can be viewed here (v1) and here (v2). You can go ahead and download Google’s original document for more insights on this news.
