How the four components of a distributed tracing system work together

LXer - Fri, 05/04/2018 - 00:16
Ten years ago, essentially the only people thinking hard about distributed tracing were academics and a handful of large internet companies. Today, it’s turned into table stakes for any organization adopting microservices. The rationale is well-established: microservices fail in surprising and often spectacular ways, and distributed tracing is the best way to describe and diagnose those failures.read more

Hawaii's Kilauea Volcano Erupts, Prompting Evacuation Orders

Slashdot - Thu, 05/03/2018 - 23:00
"Hawaii's Kilauea volcano erupted Thursday, releasing lava into a residential neighborhood and prompting mandatory evacuation orders for nearby homes," reports Chicago Tribune. The eruption comes after officials had been warning residents all week that an eruption was possible and that they should be prepared to evacuate. From the report: Hawaii County said steam and lava poured out of a crack in Leilani Estates, which is near the town of Pahoa on the Big Island. Leilani Estates has a population of about 1,500, according to the 2010 U.S. Census. But the evacuation order only covers a portion of the neighborhood. Nearby community centers have opened for shelter. The Puu Oo crater floor began to collapse Monday, triggering a series of earthquakes and pushing the lava into new underground chambers. The collapse caused magma to push more than 10 miles downslope toward the populated southeast coastline of the island.

Forty Years of Spam Email

Slashdot - Thu, 05/03/2018 - 21:30
An anonymous reader writes: The BBC has a video celebrating the 40th birthday of spam email. Here's a transcript of the video: "It is 40 years since the first spam email was sent. Marketer Gary Thuerk composed an email selling his company's newest computers and sent it to 400 users on ARPANET, which was the network that become the basis for the internet. Why is it called spam? It has been suggested that it was called spam after a song in a Monty Python sketch. Where patrons of a cafe were repeatedly offered something they didn't want. The concept of spam is nothing new. Unsolicited telegrams were sent over 100 years ago and we've come to accept junk mail as part of everyday life. Now [nearly 60%] of all email is spam. Like most rubbish, it can be found everywhere on earth."

Graphene Makes Concrete Twice As Strong While Reducing Carbon Emissions

Slashdot - Thu, 05/03/2018 - 19:25
Paige.Bennett writes: In a recent study, University of Exeter's Center for Graphene Science used nanoengineering technology to add graphene to concrete production. The resulting graphene concrete is two times stronger than traditional concrete and four times as water resistant, but with a much smaller carbon footprint compared to the conventional process of making concrete. According to the research, the addition of graphene cuts back on the amount of materials needed in concrete production by nearly 50 percent and reduces carbon emissions by 446 kg per ton.

Google Says Chrome Blocks 'About Half' of Unwanted Autoplays

Slashdot - Thu, 05/03/2018 - 18:45
When Google released Chrome 66 just over two weeks ago, it received lots of attention and praise for introducing the ability to mute autoplaying videos with sound until you press play. Today, Chrome product manager John Pallett revealed that "the new policy blocks about half of unwanted autoplays." VentureBeat reports: Pallett also shared that "a significant number" of autoplays are paused, muted, or have their tab closed within six seconds by Chrome users. He didn't say how many exactly, as the number varies significantly from site to site. But that shouldn't surprise anyone, given how much work Google put into this latest feature. Chrome decides which autoplaying content to stop in its tracks by learning your preferences and ranking each website according to your past behavior. If you don't have browsing history with a site, Chrome allows autoplay for over 1,000 sites where Google says the highest percentage of visitors play media with sound (sites where media is the main point of visiting the site). As you browse the web, Chrome updates that list by enabling autoplay on sites where you play media with sound during most of your visits, and disables it on sites where you don't.

Amazon Offers Retailers Discounts To Adopt Payment System

Slashdot - Thu, 05/03/2018 - 18:05
An anonymous reader quotes a report from Bloomberg: Amazon is offering to pass along the discounts it gets on credit-card fees to other retailers if they use its online payments service, according to people with knowledge of the matter, in a new threat to PayPal and card-issuing banks. The move shows Amazon is willing to sacrifice the profitability of its payments system to spread its use. Swipe fees are a $90 billion-a-year business for lenders such as JPMorgan Chase and Citigroup, networks including Visa and Mastercard, and payment processors like First Data and Stripe, which pocket a fraction of every sale when shoppers swipe cards or click "buy now." The financial industry's fees amount to about 2 percent of a typical credit-card transaction, or 24 cents for debit. But big stores such as Amazon and Walmart have long been able to negotiate lower rates for themselves based on their massive sales volume. Now, Amazon is offering to pass its discount along to at least some smaller merchants if they agree to embrace its Amazon Pay service. Previously, online merchants using Amazon's service have paid about 2.9 percent of each credit-card transaction plus 30 cents, which is divvied up among Amazon, card issuers and payment networks.
