A Look Into Tomorrow’s Hard Disk

Data is best stored on hard disks. It is easier to access when data stored in a hard disk. Of course, they can also be stored online. While there is nothing wrong with storing data online, you would have to rely on the internet to access your files.

With a hard disk, there’s no need to rely on the internet to access your files. Since it’s very convenient to use, a hard disk with huge data storage capacity is always in demand. The thing is, a hard disk with huge data capacity might not be portable. If it’s not portable, then it won’t be that convenient to take everywhere.

Ideally, the size of a hard disk should remain small as its data storage capacity increases. At the moment, that kind of hard disk is a myth. Hopefully, tomorrow, it becomes a reality. Here’s a look at tomorrow’s hard disk.

A recent breakthrough discovery of the world’s first high-temperature single-molecule magnet (SMM) opens doors to future exciting developments in massive storage capacity increase in hard disks without increasing their physical size.

Before the publication of the study Magnetic Hysteresis up to 80 Kelvin in a Dysprosium Metallocene Single-Molecule Magnet led by Professor of Chemistry Richard Layfield at the University of Sussex in England, it was only possible to synthesize single-molecule magnets with blocking temperatures that were reached by cooling with considerable expensive and scarce liquid helium.

The team at the University of Sussex in collaboration with Sun-Yat Sen University in China and the University of Jyväskylä in Finland, reported a new single-molecule magnet (SMM) which is a type of material that retains magnetic information up to a characteristic blocking temperature.

The characteristics of the SMMs are paving way to a very tiny device that could store huge data.

SMMs are molecules with the characteristic of remembering the direction of a magnetic field that has been applied to them over relatively long periods of time once the magnetic field is switched off. This makes possible to write information into molecules.

“Our new result is a milestone that overcomes a major obstacle to developing new molecular information storage materials and

IPFire Linux-Based Hardened Firewall Gets New Intrusion Prevention System

The IPFire open-source hardened Linux firewall has been updated today to version 2.23 Core Update 131, a release that introduces a brand new IPS (Intrusion Prevention System), various improvements, and updated components.

The most exciting thing about the IPFire 2.23 Core Update 131 release is that is ships with a new Intrusion Prevention System (IPS) that deeply inspects packets and prevents threats, thus making your networks more secure. IPFire previously used Snort as default Intrusion Detection System (IDS), but now it’s been replaced with Suricata.

“This new system has many advantages over the old one in terms of performance, security and it simply put – more modern. We would like to thank the team at Suricata on which it is based for their hard work and for creating such an important tool that is now working inside of IPFire,” explains developer Michael Tremer in the release announcem… (read more)
