3D printing polymer-derived ceramics now possible

Because ceramics cannot be cast or machined easily, three-dimensional (3D) printing enables a big leap in geometrical flexibility. We report preceramic monomers that are cured with ultraviolet light in a stereolithography 3D printer or through a patterned mask, forming 3D polymer structures that can have complex shape and cellular architecture. These polymer structures can be pyrolyzed to a ceramic with uniform shrinkage and virtually no porosity. Silicon oxycarbide microlattice and honeycomb cellular materials fabricated with this approach exhibit higher strength than ceramic foams of similar density. Additive manufacturing of such materials is of interest for propulsion components, thermal protection systems, porous burners, microelectromechanical systems, and electronic device packaging.

2nd database with 56m records exposed due to misconfiguration, looks similar to breach with 191m records

Around the same time the first database was discovered a second, smaller database was also found by researcher Chris Vickery. This second database contains voter profiles similar to those previously discovered, however, it also includes records that hold targeted demographic information.

While the overall total of records is lower (56,722,986 compared to 191 million) it’s still a concerning figure, but this discovery took a steep downturn when more than 18 million records containing targeted profile information were added to the mix.

This second database has voter information from states that began with the letters A-I, but excluding Illinois and Iowa. The scattered information suggests the data was being added in stages, and the exposed database wasn’t intended for public disclosure.
What’s in the database?

The second database contains the general voter profile, which includes a voter’s name, address, phone number, date of birth, voting record, etc. In fact, comparing records from both databases confirmed they are essentially the same, but the dates on the second database are newer (April 2015) and some of the field names are different – suggesting the core data came from the same source file.

This source file has been previously identified by political experts as Nation Builder Election Center data. This is further supported by the existence of an nbec_precinct_code and a voter ID code consisting of 32 letters and numbers separated by dashes.

As mentioned in the first story, Nation Builder is under no obligation to identify customers, and once the data has been obtained, they cannot control what happens to it.

While the previously discovered voter database contained more records, this second database, though smaller, contains more information. The standout issue is that these additional data points are targeted towards building an issues-based profile of the voter. While that might be fine for any number of election campaigns, having this data exposed to the public is a goldmine for criminals.

The second database contains several fields for custom text. Depending on the record some of them have answers, while others do not. There’s also fields that flag the profile as being copied from another data source, and those that determine if the voter has been contacted. In addition, there are fields for determining of the voter is active and if they’re a donor.

Other fields include email address, something that wasn’t part of the larger voter database covered last week; as well as records focused on health issues, gun ownership, household values (e.g., religion / social issues), fishing and hunting interests, auto racing interests, longitude and latitude of the voter, income level, and occupation.

When it comes to overlap and additions to the basic voter file, the additional fields in this second database look at gender identification, political party affiliation, political contributions, religious affiliation and if they’re a religious donor, a field denoting bible lifestyle, as well as how many robocall (auto dialed) campaigns they’ve been part of.

Dutch govt says no to backdoors, slides $540k into OpenSSL without breaking eye contact

A government position paper, published by the Ministry of Security and Justice on Monday and signed by the security and business ministers, concludes that “the government believes that it is currently not appropriate to adopt restrictive legal measures against the development, availability and use of encryption within the Netherlands.”

The conclusion comes at the end of a five-page run-through of the arguments for greater encryption and the counter-arguments for allowing the authorities access to the information.

“By introducing a technical input into an encryption product that would give the authorities access would also make encrypted files vulnerable to criminals, terrorists and foreign intelligence services,” the paper noted. “This could have undesirable consequences for the security of information communicated and stored, and the integrity of ICT systems, which are increasingly of importance for the functioning of the society.”

The formal position comes just months after the Dutch government approved a €500,000 ($540,000) grant to OpenSSL, the project developing the widely used open-source encryption software library

Why is Microsoft monitoring how long you use Windows 10?

This might seem like a slightly strange statistic for Microsoft to keep track of, but the company knows how long, collectively, Windows 10 has been running on computers around the world. To have reached this figure (11 billion hours in December, apparently) Microsoft must have been logging individuals’ usage times
