Vectrix is developing cloud security marketplace built for and by security pros

  • It has created a security marketplace where fellow security pros write modules to automate these kinds of fixes, and other security pros can take advantage without reinventing the script writing wheel every time.
  • Alex Dunbrack, company co-founder and COO, says that he and fellow co-founders, CTO Matthew Lewis and CEO Corey Mahan saw this problem first-hand in their previous jobs at PlanGrid, Vimeo and Uber.
  • The idea is to have security professionals build these modules, then give them a “royalty” and bragging rights for coming up with a viable solution.
  • Dunbrack says it’s not unlike the HackerOne model, which provides a financial incentive and community recognition to find vulnerabilities in code.
  • “We basically scope exactly what they’re going to build and the kinds of alerts that will come out of it.
  • Module writers can’t see any user information on the service, and Vectrix makes sure there are no issues like outbound requests for data.

Stop testing for normality

  • But in cases where it does not apply let’s consider how we can check for normality in a range of different samples.
  • Let’s look at the histogram for this data.
  • Now let’s perform the Shapiro-Wilk test on this data.
  • What’s actually happening is that in small samples the tests are underpowered to detect deviations from normality.
  • With this data, I would have concerns about assuming normality as there appears to be some deviation in the Q-Q plot and in the histogram.
  • Now let’s take a look at normality testing in a large sample (n=5000).
  • In small samples these tests are underpowered to detect quite major deviations from normality which can be easily detected through graphical methods.
  • In larger samples these tests will detect even extremely minor deviations from theoretical normality that are not of practical concern.

WhatsApp now lets you reverse search viral messages to check if they're bogus

  • WhatsApp has been testing features to let you perform reverse search images and text of the message to control misinformation.
  • Now, the company is rolling out the function to let you search a message on the web to check if a frequently forwarded message has correct information or not.
  • Now, you’ll see a magnifying glass next to frequently forwarded messages.
  • You can tap on that icon to launch a search on the web to see if it’s some kind of myth that’s doing the rounds.
  • Notably, WhatsApp considers messages that have been forwarded more than five times in a chain as frequently forwarded messages; those messages are marked as double arrows with forwarded label on the top.
  • So, you might have to go through multiple links on the web to determine if said message is misinformative or not.

Sending data from a Raspberry Pi Sensor unit over Serial-Bluetooth

  • When building portable sensors we often want to calibrate and double-check their readings before allowing them to log data remotely.
  • Within this tutorial, we look at exploiting the Bluetooth capabilities of a Raspberry Pi Zero (without WiFi) to transmit the initial set of results to a handheld device of our choosing.
  • For the purpose of this demo, I will describe a method using python to check things are working on a MacBook Pro. To read any data received, we can use the python serial library coupled with the following code snippet.
  • If we want to quickly check that our sensors are behaving whilst out in the field, we can make use of the Bluetooth capabilities of the Raspberry Pi. This is done by creating a Bluetooth serial port and sending data over it.

Sony's 'State of Play' Could Set the Stage for Huge PS5 Game Blowout

  • After some speculation from insiders and fans, Sony has confirmed that the next State of Play will be held on August 6, 2020, at 1 PM PT.
  • Fans shouldn’t expect any “big PS5 announcements,” said the PlayStation Twitter account, meaning that there won’t be any big reveals of games like Marvel’s Spider-Man: Miles Morales or Horizon Forbidden West.
  • This is the second disappointment to hit PlayStation fans today after Sony confirmed that PS4 controllers could not be used to play PS5 games.
  • It means that this State of Play will not give fans the PS5 price or release date news they’ve been hoping to see.
