Intel’s Ticking Atom Bomb

clock

It started somewhat innocently. Cisco released a field notice that there was an issue with some signal clocks on a range of their networking devices. This by itself was a huge issue. There had been rumblings about this issue for a few months. Some proactive replacement of affected devices to test things. Followed by panicked customer visits when the news broke on February 2nd. Cisco looked like they were about to get a black eye.

The big question that arose was whether or not this issue was specific to Cisco devices or if it was an issue that was much bigger. Some investigative work from enterprising folks like Tony Mattke (@tonhe) found that there was a spec document from Intel that listed a specific issue with the Intel Atom C2000 System on Chip (SoC) that caused it to fail to provide clock signal for onboard chips. The more digging that was done, the more dire this issue turned out to be.

Tick, Tick, Tick

Clock signaling is very important in modern electronics. It ensures that all the chips on the board are using the correct timing to process electronic impulses. If the clock signal starts drifting, you start Continue reading

Review: Arlo Pro cameras offer true flexibility for home security

Netgear’s Arlo brand of home security, network-connected cameras continues to improve, defeating every real or perceived criticism about the devices with an upgrade or improvement. Want to place in an area where there’s no network cable? Bam! Wi-Fi connection. Need to place in an area where there’s no power outlet? Bam! Battery powered! Don’t like replacing batteries? Bam! Rechargeable batteries and a quick-charge battery adapter.The latest version of this system is the Arlo Pro – it’s the most flexible camera system I’ve come across so far. After a few weeks of testing, I’ve determined that anyone who has a problem with this system (or think that it can’t do something) is just a cynical old crank.To read this article in full or to leave a comment, please click here

Microsoft readies Vista for retirement

Microsoft will stop all support for Windows Vista in two months, ending the problem-plagued operating system's usefulness when it issues final patches on April 11.The OS won't be missed: According to analytics vendor Net Applications, which estimated user share by counting unique visitors to tens of thousands of websites, Vista ran on less than 1% of all personal computers powered by Windows last month. Still, even that small percentage translated into approximately 14 million PCs when using Microsoft's claim that 1.5 billion devices run Windows.Vista was never a break-out hit for Microsoft, as were both its Windows XP predecessor and its successor, Windows 7.To read this article in full or to leave a comment, please click here

Facebook shareholders would have uphill climb ousting Zuckerberg from board

A move by a watchdog group and a small group of shareholders to oust Facebook CEO Mark Zuckerberg from his post as chairman would be an uphill battle that would be unlikely to succeed and could hurt the company, analysts said.It would completely destabilize Facebook," said Patrick Moorhead, an analyst with Moor Insights & Strategy. "Zuckerberg still makes most of the key decisions and without him it would be a major risk… I don't see a single piece of upside in removing Zuckerberg from the board."It's also unclear whether Zuckerberg could even be removed as chairman, since any shareholder vote would be advisory only.The proposal is being led by Facebook shareholders who are members of SumOfUs, an international consumer watchdog group focused on "curbing the growing power of corporations."To read this article in full or to leave a comment, please click here

Samsung Galaxy S8: What we know so far

Samsung is expected to announce its next flagship smartphone, the Galaxy S8, in April, but it looks like we won't have to wait that long to see the final product. Evan Blass from VentureBeat, who has a reputation for reporting legitimate smartphone leaks, published images last week showing the designs of the two forthcoming Samsung Galaxy S8 models.Based on the images, it looks like past reports from The Guardian were correct: The new Galaxy S8 will be available in two sizes, featuring thin bezels allowing for more screen real-estate than the Galaxy Note 7 in a smaller form factor.To read this article in full or to leave a comment, please click here

PHP vs. Node.js: An epic battle for developer mind share

It’s a classic Hollywood plot: the battle between two old friends who went separate ways. Often the friction begins when one pal sparks an interest in what had always been the other pal’s unspoken domain. In the programming language version of this movie, it’s the introduction of Node.js that turns the buddy flick into a grudge match: PHP and JavaScript, two partners who once ruled the internet together but now duke it out for the mind share of developers.In the old days, the partnership was simple. JavaScript handled little details on the browser, while PHP managed all the server-side tasks between port 80 and MySQL. It was a happy union that continues to support many crucial parts of the internet. Between WordPress, Drupal, and Facebook, people can hardly go a minute on the web without running into PHP.To read this article in full or to leave a comment, please click here

What cyberinsurance gotchas companies must be ready for

Insurance challengesImage by ThinkstockBusinesses shelled out $2 billion in cyber insurance premiums in 2015 but current projections show that astronomical growth rates will result in a market of over $20 billion by 2025. The single biggest challenge faced by insurance companies today is the lack of actuarial data on cyber attacks which makes pricing these cyber insurance policies very difficult. As a result, insurance companies are increasingly resorting to other methods to assist them in more accurately pricing these policies which is good news for them but which will result in a number of challenges for businesses.To read this article in full or to leave a comment, please click here

Can the FTC save the IoT?

Nobody in the IT industry would argue that the Internet of Things (IoT) is becoming more secure. Pretty much the opposite.But not for lack of effort. There have been multiple, ongoing initiatives over the past decade, both public and private. There have been dire warnings, publication of various standards and best practices, technology improvements, legislation to encourage threat information sharing and exhortations from government agencies, congressional committees, security firms and conference speakers.Unfortunately, none of them has worked very well so far.In spite of some of the best minds and technology improvements in the world focused on it, most of the IoT’s billions and billions of connected devices remain catastrophically insecure, lacking what experts call the most basic “security hygiene.” The flaws include hard-coded credentials, simple and default user names and passwords and the lack of any way to patch or update exploitable vulnerabilities.To read this article in full or to leave a comment, please click here

Integration of a Go service with systemd

Unlike other programming languages, Go’s runtime doesn’t provide a way to reliably daemonize a service. A system daemon has to supply this functionality. Most distributions ship systemd which would fit the bill. A correct integration with systemd is quite straightforward. There are two interesting aspects: readiness & liveness.

As an example, we will daemonize this service whose goal is to answer requests with nifty 404 errors:

package main

import (
    "log"
    "net"
    "net/http"
)

func main() {
    l, err := net.Listen("tcp", ":8081")
    if err != nil {
        log.Panicf("cannot listen: %s", err)
    }
    http.Serve(l, nil)
}

You can build it with go build 404.go.

Here is the service file, 404.service1:

[Unit]
Description=404 micro-service

[Service]
Type=notify
ExecStart=/usr/bin/404
WatchdogSec=30s
Restart=on-failure

[Install]
WantedBy=multi-user.target

Readiness

The classic way for an Unix daemon to signal its readiness is to daemonize. Technically, this is done by calling fork(2) twice (which also serves other intents). This is a very common task and the BSD systems, as well as some other C libraries, supply a daemon(3) Continue reading
