The Osborne 1: 30 years old this month

We remember the first commercial portable PC


Foxed by Vixen

Games and applications helped, but it was its portability that sold the Osborne 1. The machine had racked up sales of 11,000 units by the end of 1981.

Osborne Vixen ad

If Osborne was the first company to develop a portable computer, it was also the first technology business - the first to lend its name to the phenomenon, at least - to accidentally commit suicide by announcing new products too soon.

Tell punters there's something much better just around the corner and they'll stop buying the current model, killing your company - a situation now called the Osborne Effect.

Or so the folklore goes. Osborne announced the follow-up to the Osborne 1, the Osborne Executive, in late 1982, but it didn't ship until May 1983. It had a bigger, 7in screen than its predecessor, but also an even bigger price: $2495. It was too much - the Executive did not sell well.

That didn't matter too much because the Osborne 1 was still selling well. Until Osborne announced the Vixen - aka the Osborne 4 - which steered potential buyers away from the Osborne. Demand plunged and even massive price cuts - the machine was pitched at just $999 in August 1983 - couldn't revive it.

Osborne Computer Company was declared bankrupt in September 1983. Osborne himself was ousted, but the firm lived protected from creditors by a court order. It finally showed off the Vixen in October 1984. It went on sale the following year, but by then World+Dog wanted IBM PC compatibles, and the Vixen wasn't. OCC closed down later that year. Osborne himself died in 2003. ®

  • AI tool finds hundreds of genes related to human motor neuron disease

    Breakthrough could lead to development of drugs to target illness

    A machine-learning algorithm has helped scientists find 690 human genes associated with a higher risk of developing motor neuron disease, according to research published in Cell this week.

    Neuronal cells in the central nervous system and brain break down and die in people with motor neuron disease, like amyotrophic lateral sclerosis (ALS) more commonly known as Lou Gehrig's disease, named after the baseball player who developed it. They lose control over their bodies, and as the disease progresses patients become completely paralyzed. There is currently no verified cure for ALS.

    Motor neuron disease typically affects people in old age and its causes are unknown. Johnathan Cooper-Knock, a clinical lecturer at the University of Sheffield in England and leader of Project MinE, an ambitious effort to perform whole genome sequencing of ALS, believes that understanding how genes affect cellular function could help scientists develop new drugs to treat the disease.

  • Need to prioritize security bug patches? Don't forget to scan Twitter as well as use CVSS scores

    Exploit, vulnerability discussion online can offer useful signals

    Organizations looking to minimize exposure to exploitable software should scan Twitter for mentions of security bugs as well as use the Common Vulnerability Scoring System or CVSS, Kenna Security argues.

    Better still is prioritizing the repair of vulnerabilities for which exploit code is available, if that information is known.

    CVSS is a framework for rating the severity of software vulnerabilities (identified using CVE, or Common Vulnerability Enumeration, numbers), on a scale from 1 (least severe) to 10 (most severe). It's overseen by First.org, a US-based, non-profit computer security organization.

    US companies should be on the lookout for security nasties from Ukrainian partners following the digital graffiti and malware attack launched against Ukraine by Belarus, the CISA has warned.

    In a statement issued on Tuesday, the Cybersecurity and Infrastructure Security Agency said it "strongly urges leaders and network defenders to be on alert for malicious cyber activity," having issued a checklist [PDF] of recommended actions to take.

    "If working with Ukrainian organizations, take extra care to monitor, inspect, and isolate traffic from those organizations; closely review access controls for that traffic," added CISA, which also advised reviewing backups and disaster recovery drills.
