SAN FRANCISCO (Reuters) – Whether you are Googling on the couch, fiddling with Maps in the car or swiping through the Discover feed on the toilet, expect Alphabet Inc’s Google to put ads in several new spots this year. The ads on the Google homepage appear on what the company calls its Discover feature, a Facebook-style news feed that users swipe through to view an algorithmically personalized set of links to articles, videos and other online content. The company said on Monday that ads would run where ever Discover is available, including on its mobile website, but clarified on Tuesday that ads would only be in the Google app.

Even a software engineer with many years of working experience at a top IT company may not be an expert on system design. If you want to become an expert, you need to read many books, articles, and solve real large scale system design problems. Design a function to return the top k requests during past time interval

On Thursday, May 2, the security teams of Atlassian Bitbucket, GitHub, and GitLab learned of a series of user account compromises across all three platforms. Each of the teams investigated and assessed that all account compromises were the result of unintentional user credential leakage by users or other third parties, likely on systems external to Bitbucket, GitHub, or GitLab. On the evening of May 2 (UTC), all three companies began responding to reports that user repositories, both public and private, were being wiped and replaced with a single file containing the following ransom note:

Through immediate independent investigations, all three companies observed that user accounts were compromised using legitimate credentials including passwords, app passwords, API keys, and personal access tokens.

A thousand years ago, Native Americans in South America used multiple psychotropic plants—possibly simultaneously—to induce hallucinations and altered consciousness, according to an international team of anthropologists. Credit: Jose Capriles, Penn State

Capriles noted that the co-occurrence of harmine and DMT, which are the primary ingredients of ayahuasca—a beverage that is reported to induce hallucinations and altered consciousness—in the pouch suggests the use of this beverage as one of the drugs in the shaman’s kit. Not only does the presence of numerous compounds suggest simultaneous use of drugs and earlier use of ayahuasca, in particular, but it also indicates intricate botanical knowledge by the owner of the pouch and an effort to acquire hallucinogenic plants, as the plants came from different regions of mostly tropical South America.

Researchers at Daegu Gyeongbuk Institute of Science and Technology (DGIST) have developed film-type, graphene-based multi-functional transparent energy devices. Senior researcher Changsoon Choi’s team actively used single-layered graphene film as electrodes in order to develop transparent devices. The research team designed a structure for self-charging electronic devices by inserting the energy storage panel inside the upper layer of power devices, and the energy conversion panel inside the lower panel.

SAN FRANCISCO (Reuters) – Alphabet Inc’s Google will begin featuring ads on the homepage of its smartphone app worldwide later this year, it said on Tuesday, giving the search engine a huge new supply of ad slots to boost revenue. The ads on the Google homepage appear on what the company calls its Discover feature, a Facebook-style news feed that users swipe through to view an algorithmically personalized set of links to articles, videos and other online content.

Mayo Clinic’s belief in the importance of connection goes beyond attitudes and language to practical steps taken to see that connection is infused in the culture. Our current epidemic of social disconnection has arisen from multiple avenues including loneliness, social isolation and the busyness and increased screen time of modern life crowding out time for face-to-face human connection. Michael Lee Stallard, president and cofounder of Connection Culture Group, is a thought leader and speaker on how effective leaders boost human connection in team and organizational cultures to improve the health and performance of individuals and organizations.

This is the account I use to send and receive on the Stellar network, when transacting with other Keybase users. I have 2 other accounts; I send from them not into Keybase chat, but to regular old Stellar addresses. Ah, so you know something about Stellar…yes, using other wallets you can send to [username]*keybase.io to reach a Keybase user.

UpCloud seems to have the best performance but all of these apart from Hetzner charge $40/month for a cloud server with 4 cores and 8 GB of ram. Hetzner gives me twice as much memory at half of the price, but performance isn’t great from my testing/benchmarking, especially concerning the storage. I will probably need 7 servers for my setup initially with 4 cores and at least 8 GB of ram and decent storage performance.
