Months ago I noticed something strange in the Little Snitch Network Monitor: Safari was still connecting to web sites after every window had been closed.

Yesterday the New York Times and ProPublica posted a lengthy investigation based on leaked NSA documents, outlining the extensive surveillance collaboration between AT&T and the U.S. government…
Ngrok is a fantastic tool for creating a secure tunnel from the public web to a machine behind NAT or a firewall. Sadly, it costs money and it’s proprietary. If you’re a developer, odds are that you’re already renting a server in the public cloud, so why not roll your own ngrok?
I found this tiny fanless Thunderbolt 25G Ethernet adapter. With a little tinkering, it actually works.
One of my longest-running projects has been an open hardware Ethernet switch. This has been one of the key driving forces behind many of my other projects, such as ngscopeclient and the high speed probes. It was also the project that got me into high speed digital design.
Linux phones now have the hardware and software to succeed, but it is an open question whether they will become a viable alternative to the Android/iOS duopoly.
Feb 2015: 3½ years later, we’re in a better place. The new IE Spartan project has killed off document modes . (Technically, still possible in firewall environments, but… effectively dead for us.)

We are under warning that macOS 27 is likely to remove support for AFP, and lately some additional requirements for connection to certain servers. This explains how these could affect you.
Infrastructure “We should own our infrastructure.” A lot of people would instinctively nod in agreement with that statement. Yet who “we” refers to shifts depending on the type of infrastructure. Highways, railways, bridges, and ports require nation-scale efforts. The water supply is usually put into the hands of…
When I first arrived at MIT in 2010, I was awed by how much computing infrastructure was readily available. Dorm rooms had 100 megabit inter...

Since this happened after I was banned from Freenode , I didn't get to observe this first hand, but this is the situation as I now understand it.
Gnutella Explanation
Late last year, I started experiencing some unusual intermittent connection issues on my Desktop. In general, I had a stable connection with average latency; however, at (seemingly) random times throughout the week, I would start experiencing sudden 2000ms+ latency spikes every couple of seconds.

Thanks HN folks for all the comments. To clarify a bit, the cables are pulled through PVC conduits under the flooring before being buried in cement. Currently the hypothesis for why the cable disintegrated so quickly is hydrolysis. Singapore is extremely humid after all. A second possibility is that I keep the…
