Running a recursive resolver does protect against one very specific kind of threat: a malicious recursive resolver that has decided to log all of my queries. DoH absolutely does not protect against this specific threat, because it'

This extreme focus on DoH is really concerning me. If you're worried about your recursive DNS resolver spying on you, the correct solution is to run your own recursive resolver. I've been running unbound(8) on my OpenBSD systems a

A good counterexample, showing the benefits of live streaming, is the continuing protests in Hong Kong. Many of the local media organisations have been streaming their coverage of the protests (primarily via their Facebook pages). At time

In terms of unit economics, UberX is still (mostly) sound -- the rider is paying a fare based roughly on time/distance, and the driver is paid a fare that's also based roughly on time/distance; it's very rare to see a r

Uber really likes hexagons. Their internal name for driver promotions is even "hexcentive"! I've long wondered what compelled Uber to use hexagons to define their various promotion boundaries, because it's not a very u

Yep, the original "serverless" was using FTP to upload CGI scripts (Perl, PHP, or even C) into your /cgi-bin directory, whereupon your webhost would magically execute said script each time a client sent an HTTP request. No p

An electricity grid does a pretty good job of connecting reservoirs in the high mountains with distant cities and other loads. Granted there are some transmission inefficiencies, but still far better overall efficiency than any heat engine

For those interested in ART, there is an IETF working group attempting to standardise it as the "Messaging Layer Security" protocol. Their website [1] has a draft protocol document [2] which explains the ART scheme from a concret

So it turns out that the attack "was possible due to the discrepancy between the proof of OCB2 and the actual construction" (according to the paper). That's a scary thought. I wanted to learn a little bit more about progress

This is really cool! It's rare to see new implementations of awk these days. Bonus points for running it through the nawk test suite. In my opinion /usr/bin/awk is a thing of beauty. Certainly it's the most usabl

Yes, if the "destination" is stdout (or a pipe/file) then the obvious loop works just fine: function join(ARRAY) { for (i=0; i in ARRAY; i++) printf "%s", ARRAY[i]; } But if you need the result back as

But the infrastructure (underground ducts, fibre junction boxes, and the GPON fibre) will last for decades, so it's a very reasonable investment to be making.

New Zealand is currently in the process of rolling out fibre connections in almost every urban area of the country (target is 87% of households) and the amazing thing is that a basic fibre connection is now the same price as an ADSL/
