Surfing On Tech Waves With Supermicro

If money were no object and accountants allowed companies to write off investments in systems instantly, then datacenters would be tossing hardware into the scrap heap as soon as new technology came along. But in the real world, companies have to take a more measured approach to adding new systems and upgrading old ones, and that can make the time when customers buy shiny new boxes a bit tough to predict.

Forecasting sales and trying to close them are two of the many challenges that all server, storage, and switching vendors face, and Supermicro, which straddles the line between the …

Open source routers deliver low cost, flexibility

Economical and flexibleOpen source software offers an economical and flexible option for deploying basic home, SMB or even enterprise networking. These open source products deliver simple routing and networking features, plus they are combined with security functionality, starting with a basic firewall and possibly including antivirus, antispam and Web filtering.

IBM cloud chief: The next phase of cloud is a race to add value

At 105 years old, IBM has been through more than a few major technology transformations. Arguably, none is bigger than the current retooling of the company around cloud computing – an effort overseen by Robert LeBlanc, senior vice president, IBM Cloud. LeBlanc says IT leaders and business executives aren’t caught up in Wall Street’s worries over IBM’s revenue declines or the pace of the cloud transformation. BB: Is your sales force fully onboard with selling those cloud services versus the traditional on-premise offerings? What have you done to incent the sales force to make that shift? BB: Partnerships seem to be another important part of your strategy. You have an expanded partnership with VMware that you spoke about at VMworld. You have a partnership with Workday. Can you explain the overall partner strategy for advancing the cloud position and what should customers expect in the way of future partnerships?To read this article in full or to leave a comment, please click here(Insider Story)

What’s the testimonial of passwords?

In this case described by Orin Kerr, the judge asks if entering a password has any testimonial other than "I know the password". Well, rather a lot. A password is content. While it's a foregone conclusion that this encrypted drive here in this case belongs to the suspect, the password may unlock other things that currently cannot be tied to the suspect. Maybe the courts have an answer to this problem, but in case they haven't, I thought I'd address this from a computer-science point of view.


Firstly, we have to address the phrasing of entering a password, rather than disclosing the password. Clearly, the court is interested in only the content of the disk drive the password decrypts, and uninterested in the password itself. Yet, entering a password is the same as disclosing it. Technically, there's no way to enter a password in such a way that it can't be recorded. I don't know the law here, and whether courts would protect this disclosure, but for the purposes of this blog post, "entering" is treated the same as "disclosing".

Passwords have content. This paper focuses on one real, concrete example, but let's consider some hypothetical cases first.

How to use Ansible ios_config to configure devices

A lot of new networking modules were released as part of Ansible 2.1. The Cisco IOS, IOS XR, NXOS, Junos and Arista EOS platforms got three common modules, the platform_config, platform_command and platform_template. The command and template modules more or less explains themselves. The config modules have some more tricks to them and I’ve gotten a few questions about how they work. In this article I’m going to focus on the ios_config module and show how you can use it to configure Cisco IOS devices. Future version of Ansible will add more parameters, this article is for Ansible 2.1.

Krebs’ site under attack after alleged owners of DDoS-for-hire service were arrested

After security journalist Brian Krebs exposed the DDoS-for-hire service, vDOS, and the alleged owners of the service were arrested, a massive attack was launched against the Krebs on Security site.Last Thursday, Krebs wrote about vDOS and the two 18-year-old Israeli hackers running the DDoS attack service. In the past two years, the duo launched over 150,000 attacks and made at least $618,000. vDOS had been hacked and Krebs had obtained a copy of the vDOS database.vDOS had paying subscribers with the cost depending upon how many seconds the DDoS attack lasted. Krebs reported, “In just four months between April and July 2016, vDOS was responsible for launching more than 277 million seconds of attack time, or approximately 8.81 years’ worth of attack traffic.”To read this article in full or to leave a comment, please click here

Eero, my Wi-Fi hero

Getting really good Wi-Fi coverage is hard in most buildings unless you can place your access point in the center of the building and the building doesn’t have lots of metal in it to distort and attenuate the signal. A cheap solution is to use a range extender to improve the reach of your Wi-Fi but, unfortunately, many of these products use a single radio to repeat the signal which results in reduced bandwidth. There is, however, a better way: Eero, a company that’s been shipping their eponymously named product for just over a year, have the best solution I’ve tested so far. The eero system (I must note here that the company and devices are named after the architect Eero Saarinen, famous for his clean, sophisticated design aesthetic, and Eero writes the device’s name in the style of e.e. cummings: all lower case, thus “eero”) creates a mesh network, each node having two radios so that they can send and receive simultaneously using adaptive routing to maximize throughput. The product really is nicely designed with the same kind of polished look and feel that characterizes Apple’s products (in fact, the design strikes me a much like the Continue reading

Down with idiotic disclaimer footers and dumb surveys!

How often do you receive an email message with a footer like this: The contents are not to be disclosed to anyone other than the addressee. Unauthorised recipients must preserve this confidentiality and should please advise the sender immediately of any error in transmission. This gem of pseudo-legal nonsense is from a message that I did not solicit and is the work of eDigitalResearch.com at the behest of ”The Expedia Customer Experience Team." At some point, someone in either or both organizations must have thought this footer was necessary which is curious because the serious, weighty, highly private content in the message was a customer satisfaction survey addressed to me. Was this, you might be wondering, a very personalized survey with, perhaps, sensitive, personal data included? Nope, and here, at the very slight risk of their dogs of law snapping at me, is the message that had the above footer appended:To read this article in full or to leave a comment, please click here

ISSU Upgrade of Cisco Catalyst 6880-X VSS Cluster and 6800ia FEX extenders

How does Internet work - We know what is networking

I wrote all the details about ISSU procedure steps and explained each step extensively. For a shorter update procedure guide check abbreviated article: Short list of upgrade steps without extensive explanations “Cisco Catalyst 6880-X VSS ISSU Upgrade Steps“ Intro Cisco spoiled us over the years with great and detailed documentation on each technology and hardware component they support. Still, I managed to find a part where documentation is not detailed enough to give you definite number of steps to get things done. While preparing for software upgrade of Cisco Catalyst 6880-X VSS cluster I stumbled on one of the first examples of

US consumer product safety agency warns against use of Galaxy Note 7

Samsung Electronics’ woes mounted Friday with the U.S. Consumer Product Safety Commission urging consumers to power down and stop charging or using their Galaxy Note 7 smartphones, after reports of the overheating and bursting of the lithium-ion battery in the device in some cases. The statement by the CPSC comes a day after the Federal Aviation Administration advised passengers not to turn on, charge or stow away their devices in checked baggage when on board aircraft. Three airlines in Australia, including Qantas, its unit Jetstar and Virgin Australia, have also prohibited their passengers from using or charging the Galaxy Note 7 during flight.To read this article in full or to leave a comment, please click here
