Cheating allegations against poker player Mike Postle halt livestreamed games

The RFID cards contain chips, that combined with readers in the poker table, transmit information about each player’s hole cards, so that viewers can see the cards on the broadcast (which is on a 30-minute delay to protect game integrity).

Bitcoin Isn’t the World’s Most-Used Cryptocurrency

While concrete figures on trading volumes are hard to come by in this often murky corner of finance, data from CoinMarketCap.com show that the token with the highest daily and monthly trading volume is Tether, whose market capitalization is more than 30 times smaller. Tether’s volume surpassed that of Bitcoin’s for the first time in April and has consistently exceeded it since early August at about $21 billion per day, the data provider says.

CentOS 8 is finally here

CentOS offers a bit of a different take on installing and updating packages. First off, the default package manager has migrated from YUM to DNF. The command structure for each is quite similar, so instead of running a command like:

sudo yum install httpd

You’d issue the command:

sudo dnf install httpd

For more information on DNF, see How to use the DNF package manager.

Linux Foundation exec believes edge computing will be more important than cloud computing

When Joshipura is talking about edge computing, he means compute and storage resources that are five to 20 milliseconds away. He also means edge computing should be an open, interoperable framework. This framework should be independent of hardware, silicon, cloud, or operating system. Open-edge computing should also work with any edge-computing use case: Internet of Things (IoT) edge, a telecom edge, cloud edge, or enterprise edge, whatever, “Our goal here is to unify all of these.”

To make this happen, Joshipura announced two more projects were being incorporated into LF Edge: Baetyl and Fledge.

LastPass bug leaks credentials from previous site

Attackers could lure users on malicious pages and exploit the vulnerability to extract the credentials users had entered on previously-visited sites. According to Ormandy, this isn’t as hard as it sounds, as an attacker could easily disguise a malicious link behind a Google Translate URL, trick users into visiting the link, and then extract credentials from a previously visited site.

Los Angeles OKs a deal for record-cheap solar power and battery storage

Under the 25-year deal with developer 8minute Solar Energy, the city would buy electricity from a sprawling complex of solar panels and lithium-ion batteries in the Mojave Desert of eastern Kern County, about two hours north of Los Angeles. The Eland project would meet 6% to 7% of L.A.’s annual electricity needs and would be capable of pumping clean energy into the grid for four hours each night.

Is Perl 6 Being Renamed?

The BBC, the world’s largest broadcaster, had Perl everywhere. They decided to ditch it. MongoDB claims that their clients aren’t developing any new projects in Perl, so they’re ditching Perl 5 support. Other companies are continuing this trend and this is, as potential clients have told me, because they’re tired of waiting for Perl 6. They think Perl 6 is the successor to Perl 5 and given the name, it makes perfect sense. Combine that with the negative press about Perl 5 and you get into “nobody got fired for buying IBM” territory, but s/Perl/$other_language/g.

How malformed packets caused CenturyLink’s 37-hour, nationwide outage

The switching module sent these malformed packets “as network management instructions to a line module,” and the packets “were delivered to all connected nodes,” the FCC said. Each node that received the packet then “retransmitted the packet to all its connected nodes.”

But the outage continued because “the malformed packets continued to replicate and transit the network, generating more packets as they echoed from node to node,” the FCC wrote. Just after midnight, at least 20 hours after the problem began, CenturyLink engineers “began instructing nodes to no longer acknowledge the malformed packets.” They also “disabled the proprietary management channel, preventing it from further transmitting the malformed packets.”

Counterintuitive physics property found to be widespread in living organisms

Ever since the late 19th century, physicists have known about a counterintuitive property of some electric circuits called negative resistance. Typically, increasing the voltage in a circuit causes the electric current to increase as well. But under some conditions, increasing the voltage can cause the current to decrease instead. This basically means that pushing harder on the electric charges actually slows them down

Why putting a script in /etc/cron.hourly is not working?

As you’ve probably seen in the comments to your question, the cronjobs in /etc/cron.hourly (and the other, similar directories) are executed by run-parts. run-parts is a little picky about filenames. By default it doesn’t execute files whose filenames contain anything other than (all of those from ASCII)

  • uppercase letters
  • lowercase letters
  • digits
  • underscores
  • dashes (“minus signs”)

So if your script has a filename of for example “myscript.sh”, it just is ignored, because run-parts does not like the dot.
