Evidence-based Troubleshooting: Observations on Problem-solving from Economic Psychology
Excellent piece on psychology of being a technology worker. MUST READ. For those of us who work in technology, we pride ourselves in our rationalism. We deal in the territory of binary math, algorithms, and logic. Yet we often fail to step back and see ourselves as mere mortals. We acknowledge some disciplines suffer from […]

ExpertExpress Evolved into a Team of Experts
Years ago, I decided to try out another idea: solving real-life challenges with the help of an easy-to-consume online consulting service. When I discussed the idea with my friends during one of the early Networking Field Day events the opinion was pretty unanimous: “this will never work”
Fortunately, they were wrong. Not only did ~100 customers decided to use it in the meantime, the simple idea grew to a point where I couldn’t do it all on my own.

I’m excited to announce that I’ve joined Cloudflare as Head of Asia. This is an important time for the company as we continue to grow our presence in the region and build on the successes we’ve already had in our Singapore office. In this new role, I’m eager to grow our brand recognition in Asia and optimize our reach to clients by building up teams and channel partners.
A little about me
I’m a Californian with more than 20 years of experience growing businesses across Asia. I initially came to Asia with the Boston Consulting Group and since then I’ve helped Google and Twitter start and grow their businesses in Singapore and Asia. In many cases throughout my career, I’ve been one of the very first employees (sometimes the first) on the ground in this part of the world. To me, the Asian market presents an often untapped opportunity for companies looking to expand, and it’s a challenge that has appealed to me throughout my career.

HTTPS or bust: Chrome’s plan to label sites as “Not Secure”
Google just announced that beginning in July 2018, with the release of Chrome 68, web pages loaded without HTTPS will be marked as “not secure”.
More than half of web visitors will soon see this warning when browsing unencrypted HTTP sites, according to data from Cloudflare’s edge that shows 56.62% of desktop requests originate from Chrome. Users presented with this warning will be less likely to interact with these sites or trust their content, so it’s imperative that site operators not yet using HTTPS have a plan to do so by July.
How did we get here (and why)?
To those who have followed the Chrome team’s public statements, this announcement comes as no surprise. Google has been gearing up for this change since 2014, as Chrome boss Parisa Tabriz tweeted and Chris Palmer memorialized in a widely distributed email. While this step is an important and potentially jarring one for users, it’s by no means the last step that Google will take to influence website administrator behavior for the better.
But why are they making this change (now)? Google’s primary motivation for driving HTTPS adoption is simple: a safe browsing experience is good for business. Users that feel Continue reading

Indigenous Connectivity Summit Participants Share Their Stories
Madeleine Redfern, the mayor of Iqaluit – the largest and only city in Nunavut, Canada – has a colorful way of describing how sparsely populated the territory is. “The seals outnumber the people.” With a population of just over 35,000 people spread out over an arctic 1,750,000 square kilometers, Internet access is a challenge. In fact, according to Redfern, her most favorited tweet was that she couldn’t tweet… because the connection was too slow.
Madeleine Redfern participated in the first ever Indigenous Connectivity Summit last November. She and other participants shared their experience and expertise to help close the connectivity gap in Indigenous communities. Many also sat down for brief interviews with the 1st-Mile Institute, a New Mexico nonprofit that has initiated a local “Broadband for All” program. The videos are now available to watch on the 1st-Mile Institute’s website.
You can also find the videos on the Internet Society’s Indigenet page, which includes resources from the Summit including the presentations, the policy brief Spectrum Approaches for Community Networks, and other ways to get involved!

HPE Leads Data Center Server Market, IHS Says
Enterprises continue to be the biggest server buyers — for now.
The DNS Negative Cache
Considering the DNS query chain—
- A host queries a local recursive server to find out about
banana.example - The server queries the root server, then recursively the authoritative server, looking for this domain name
banana.exampledoes not exist
There are two possible responses in this chain of queries, actually. .example might not exist at all. In this case, the root server will return a server not found error. On the other hand, .example might exist, but banana.example might not exist; in this case, the authoritative server is going to return an NXDOMAIN record indicating the subdomain does not exist.
Assume another hosts, a few moments later, also queries for banana.example. Should the recursive server request the same information all over again for this second query? It will unless it caches the failure of the first query—this is the negative cache. This negative cache reduces load on the overall system, but it can also be considered a bug.
Take, for instance, the case where you set up a new server, assign it banana.example, jump to a host and try to connect to the new server before the new DNS information has been propagated through the system. On Continue reading
