Pirates and the habit of shipowners to hide responsibilities in a maze of sub contractors, charterers, and flags of convenience. The the maritime industry's track record of preventing oil spills is pretty bad. Do we really want those p

Looking at pre-car city street scenes, not many people rode horses. Most horses pulled carts and coaches. Of course, a shying horse attached to one of those can still kill people.

With a firewall, the application knows its public-facing ipv6 address/src port number without STUN. A stateful firewall does not alter packets. It can open the firewall simply by sending something. If it can communicate its public-faci

Most of the applications that could communicate peer-to-peer use relay servers that make delay and scalability worse. Some combinations of NAT may sometimes work without a relay server, but figuring this out is complex and increases connect

I am working for a Big Corp. I have see many instances where we made expensive contracts with small companies maintaining open source solutions. It fits existing processes and we have somebody who will fix stuff. Most of the time, it would

That's the thing that I find unconvincing about webauthn. There seems to be no other way than to associate several key devices for every website you are using if you are concerned about losing a key device (or get a new phone, new lapt

The reason for doing microservices I've been given by a two person developer team that had created a 15+ microservice single-server k8s monster was: 'this is how it is done today' Yeah, IT is like the fashion industry.

More interesting data for the identity provider.. Leaving the filtering to the client side is a less intrusive method and puts the responsibility into the hands of parents (or work places). rtalabel.org proposes simple well-known meta tags

My late father used to be a service technician with Royal McBee who sold the LGP-30 in Europe. Before I got my ZX-81, he gave me the LGP-30 manual as an introduction to programming. He had some stories about programmers optimizing drum mem

IBM AIX's TCP can either do selective ACKs or handle out-of-order packets. Which we were told when a firewall started reordering packets. It simply dropped out of order packets and therefore triggered congestion handling.

So true, but how many developers know about them? The API situation does not help either.

Well, early XFree86 had strong warnings that wrong settings could result in monitor damage (which made configuring X11 even more daunting). Nothing new under the sun.

That was the idea of CargoLifter ( https://en.wikipedia.org/wiki/CargoLifter ). The plan was to build an airship that can lift 160 t of oversized payload and beat train or road transport on price and speed. They ran out

I agree. It is curious that pictures like this https://content.api.news/v3/images/bin/42fa4e0d62be371a52239... (Tenerife Airport disaster w 583 fatalities) did not have that impact on using passenger jets. It

From my experience, a TCP implementation can look ok on the surface but still be horrible. Retransmission covers up a lot of problems.

If it is just to a neighboring country, it usually works well. Or if it is a direct connection through several countries. But if you have to change in a country you are just passing through, it all breaks down. Best to install the apps of a

The FTTH GPON standard is inherently asymmetric as well. In densely populated areas it is much cheaper than point to point fiber, so you will see asymmetric speed in contracts for quite some time. And of course marketing people really love

They call REST anything that uses JSON over HTTP nowadays. What I don't get, when they don't know or don't want to do REST, why they are not just calling their API JSON/HTTP?

If you have to manage 100s of devices, you prefer thin clients. As a user, you want control over your device and rich functionality. Dumb clients usually give you dumb services. I thought we have moved past thin clients and moved on to cen

I guess that in the automotive industry different models are often only done to achieve price differentiation or to serve local markets. The technical differences are superficial.
