Quantum dots could bridge gap between electronic and quantum computers

An intriguing type of quantum computing is one step closer to practicality with the announcement today that experts at the Los Alamos National Laboratory, Stanford University and the Technical University of Munich have managed to solve one of the technology’s major problems using common semiconductor materials.The idea behind quantum computing, in the broadest possible strokes, is to use the quantum state of a small particle to store information. The advantage is that each of these particles, called qubits, can store a large range of values, while the regular bits at the core of electronic computers can only represent zero or one. Consequently, the theory goes, certain kinds of computation could be performed at vastly superior speeds.To read this article in full or to leave a comment, please click here

Time for change

Its time for a change!

It was a tough decision, but i’ve decided that I need some new challenges in my professional life. To that effect, i’ve quit my old job and joined a different VAR/SP where I will be working in a skilled team of network engineers.

My duties will include maintaining and expanding a growing MPLS network, with all the services one can build on top of such a beast. Along with that, I will be attached to large enterprise customers, helping with design and implementation.

The new job is very supportive of my effort to go after the elusive CCDE certification, which was a big part of my decision as well, so expect more updates in that direction!

I’ve had some great years with awesome coworkers, but I have great confidence in the coming years as well!

Finally, a big thanks to my family and friends for supporting me through this decision process!

Reaction: Innovation and the Internet

Industries mature, of course. That they do so shouldn’t be surprising to anyone who’s watched the world for very long. The question is — do they mature in a way that places a few players at the “top,” leaving the rest to innovate along the edges? Or do they leave broad swaths of open space in which many players can compete and innovate? Through most of human history, the answer has been the first: industries, in the modern age, tend to ossify into a form where a few small players control most of the market, leaving the smaller players to innovate along the edges. When the major impetus in building a new company is to “get bought,” and the most common way for larger companies to innovate is by buying smaller companies (or doing “spin ins”), then you’ve reached a general point of stability that isn’t likely to change much.

Is the networking industry entering this “innovation free zone?” Or will the networking industry always be a market with more churn, and more innovation? There are signs in both directions.

For instance, there’s the idea that once technology reaches a certain level of capability, there’s just no reason for Continue reading

Cisco patches permission hijacking issue in WebEx Meetings app for Android

Cisco has fixed a vulnerability in its WebEx Meetings application for Android that allowed potentially rogue applications to hijack its permissions.The issue, which affected all versions of the app older than 8.5.1, stemmed from the way custom application permissions were implemented and assigned at initialization time.In addition to the default permissions defined by the OS, applications can declare and request custom permissions, a feature that the Android developers recommend be used only if absolutely necessary. It is also possible for apps to request to use custom permissions declared by another application.To read this article in full or to leave a comment, please click here

Google accused of tracking school kids after it promised not to

Google has been collecting information about schoolchildren's browsing habits despite signing a pledge saying it was committed to their privacy, the Electronic Frontier Foundation said in a complaint filed Tuesday.The digital rights group said Google's use of the data, collected through its Google for Education program, puts the company in breach of Section 5 of the Federal Communications Act and asked the Federal Trade Commission to investigate.“Despite publicly promising not to, Google mines students’ browsing data and other information, and uses it for the company’s own purposes," the EFF said.To read this article in full or to leave a comment, please click here

IRS says it will get a warrant before using cell-site simulators

The U.S. Internal Revenue Service is drafting a policy to restrict the use without a warrant of cell-site simulator technology to snoop on the location and other information from mobile phones.The head of the IRS, John Koskinen, wrote in a letter that the agency was drafting a policy that would mirror an earlier Department of Justice rule,  which requires a search warrant supported by probable cause before using the technology,  except in exigent or exceptional circumstances.INSIDER: 5 ways to prepare for Internet of Things security threats Cell-site simulators, also referred to as stingrays or 'IMSI catchers,' track the location and other information from mobile phones by mimicking cellphone towers. The use of the technology without a warrant by law enforcement has been criticized by civil rights groups.To read this article in full or to leave a comment, please click here

Is Flow-Based Forwarding Just Marketing Fluff?

When writing the Packet- and Flow-Based Forwarding blog post, I tried to find a good definition of flow-based forwarding (and I was not the only one being confused), and the one from Junos SRX documentation is as good as anything else I found, so let’s use it.

TL&DR: Flow-based forwarding is a valid technical concept. However, when mentioned together with OpenFlow, it’s mostly marketing fluff.

Brocade VDX SNMP Changes

Brocade tightened up some SNMP settings with NOS 6.0.x. This improves security, but it also means that you will need to modify your configuration if you upgrade. If you don’t, SNMP won’t work, and you’ll get errors with BNA/Nagios/Cacti/etc. Here’s the changes, and how to get SNMP working with NOS 6.0.x. NB This applies to VDX Data Centre switches. Other product lines have different configuration.

Usual disclaimers apply: Yes, I work for Brocade. Doesn’t mean that I’m an official spokesperson, or a replacement for TAC. I’m just putting this info out there to help others who get bitten by this.

5.x and earlier defaults

NOS 5.x and earlier had default SNMP settings that looked like this:

snmp-server contact "Field Support."
snmp-server location "End User Premise."
snmp-server sys-descr "Brocade VDX Switch."
snmp-server community ConvergedNetwork
snmp-server community OrigEquipMfr rw
snmp-server community "Secret C0de" rw
snmp-server community common
snmp-server community private rw
snmp-server community public
snmp-server user snmpadmin1 groupname snmpadmin
snmp-server user snmpadmin2 groupname snmpadmin
snmp-server user snmpadmin3 groupname snmpadmin
snmp-server user snmpuser1
snmp-server user snmpuser2
snmp-server user snmpuser3

Yeah. Pretty open. So if you’re lazy, and your NMS tried a default discovery string of Continue reading

Ransomware and scammy tech support sites team up for a vicious one-two punch

Symantec has seen a curious fusing of two pernicious online threats, which would cause a big headache if encountered by users.Some websites offering questionable tech support services are also dishing up ransomware, which locks up a users files until they pay a fee to decrypt them.The support scams involve trying to convince users they have a computer problem and then selling them overpriced software or support services to fix it. It's often done via a pop-up message that urges people to call a number or download software.To read this article in full or to leave a comment, please click here

Toy maker VTech says breach hit 6.4 million kids’ accounts

Educational toy maker VTech has said 11.6 million accounts were compromised in a cyberattack last month, including those of 6.4 million children.The total number of accounts affected is nearly double that reported last week by the security news site Motherboard, which interviewed a hacker who claimed credit for the breach.Most of the account holders were in the U.S., including 2.2 million parents and 2.8 million children, VTech said Wednesday in Hong King, where the company is based. France, the U.K., Germany and Canada round out the top five countries hit, VTech said in an updated FAQ.To read this article in full or to leave a comment, please click here
