Worth Reading: On the Quants and the Creatives

One of the things I find most interesting about the history of advertising is the long-running conflict between the “creatives” and their more quantitative, data-driven opponents within ad agencies. It’s a long-running, widespread opposition between a more humanistic, intuitive, interpretative style of decision-making and professional practice and a more rules-driven, empirical, formalistic approach. -via Easily Distracted

Are you ready for Country as a Service? Estonia offers ‘e-residence’

Way back in the old days—say, five minutes ago—if you wanted to take advantage of what a country had to offer, you had to actually go there. But in the age of “Everything as a Service,” physically locating yourself in the country you want to “reside” seems so old school. At least, that seems to be the rationale behind Estonia’s efforts to offer something called “e-residency.” As Taavi Kotka, Estonia's CIO, explained in Business Insider last week, "It’s called CaaS. There’s SaaS. We’re Country as a Service.”Estonia is cooler than you think Here’s the deal. If you didn’t know—and there’s really no big reason you should have—the Republic of Estonia is a tiny but technically advanced Baltic country of just 1.3 million people. According to Wikipedia, “Estonia is often described as one of the most internet-focused countries in Europe,” and it “boasts “an advanced, high-income economy and high living standards. Unfortunately, the population has been shrinking for decades.To read this article in full or to leave a comment, please click here

Securing BGP: A Case Study (10)

The next proposed (and actually already partially operational) system on our list is the Router Public Key Infrastructure (RPKI) system, which is described in RFC7115 (and a host of additional drafts and RFCs). The RPKI systems is focused on solving a single solution: validating that the originating AS is authorized to originate a particular prefix. An example will be helpful; we’ll use the network below.

RPKI-Operation

(this is a graphic pulled from a presentation, rather than one of my usual line drawings)

Assume, for a moment, that AS65002 and AS65003 both advertise the same route, 2001:db8:0:1::/64, towards AS65000. How can the receiver determine if both of these two advertisers can actually reach the destination, or only one can? And, if only one can, how can AS65000 determine which one is the “real thing?” This is where the RPKI system comes into play. A very simplified version of the process looks something like this (assuming AS650002 is the true owner of 2001:db8:0:1::/64):

  • AS65002 obtains, from the Regional Internet Registry (labeled the RIR in the diagram), a certificate showing AS65002 has been issued 2001:db8:0:1::/64.
  • AS65002 places this certificate into a local database that is synchronized with all the other operators participating in Continue reading

IDG Contributor Network: The contract process, and software’s role in it

As a freelancer who has worked for a large range of big companies over the years, I'm all too aware of how important contracts are to an enterprise's working.I've long been amazed that coming to a decision about a body of work tends to be a relatively quick process, but actually negotiating and formalizing the contract becomes an incredibly drawn out process. I've often laughed when I've been sent a 40-page contract by a vendor for a tiny piece of work. I have neither the legal skills nor the legal budget to pore through the document. I tend to just let things slide—at the end of the day, I'm just keen to get the job happening.To read this article in full or to leave a comment, please click here

Is student loan assistance the next big thing in corporate recruiting?

As of 2015, more than 40 million Americans had some kind of student loan debt. According to a survey from education finance portal iontuition of the 1,000 student-loan-debt-holders surveyed in July 2015, 80 percent say they'd appreciate it if their employers helped with repayment of their debt through a matching opportunity, much like a 401k. As businesses struggle to attract and retain talent, is student loan repayment assistance becoming a must-have benefit?To read this article in full or to leave a comment, please click here
