I think Safari is WebKit.

In my opinion NAT is a hack that makes lot of things harder than they should be. STUN and TURN are services that are created because there is no easy way to connect two hosts between different NATs. UPnP for port forwarding is another. CG-NAT is even worse. I have heard of so many people having problems with it.

Breadcast is messy. It is like screaming into a room and waiting for an answer. Multicast lets the computer decide if it wants and needs to listen to a specific group message.

IPv4 didn’t have cidr from the beginning. They only had classes. IPv6 was designed with complex routing and sub routing in mind.

They never wanted to worry about address space size again. And this makes subnetting much easier. I have a /56 allocation so I could do 256 /64 subnets. I hope that at some point home routers will have the option for seperate subnets built in. This way you could easily have guest, IoT, work or whatever networks without NAT.

One thing you have to consider though is that the minimum network size that allows autoconf is /64 and that because of the privacy extension a device usually has 3-4 IPv6 adresses.

IPv6 changed some things. First and foremost it has a huge address space:

• IPv4: 4294967296 (2^32)
• IPv6: 340282366920938463463374607431768211456 (2^128)

Then they simplyfied some things:

• Removed Broadcast in favor of Multicast and Anycast
• Added autoconfiguration without a DHCP server
• Better subnetting support

And much more

IPv6 traffic is globally steady at around 37%. So it isn’t a majority by far.

The perpetual chicken egg problem of IPv6: many users don’t have IPv6 because it’s not worth it because everything is reachable via IPv4 anyways because IPv6 only service don’t make sense because they will only reach a subset of users because many users don’t have IPv6…

Wenn man im Urlaub ist, bleibt man im Urlaub. Die Arbeit existiert nicht wenn ich Urlaub habe. Steht mir gesetzlich zu.

Es gab tatsächlich einen Vorschlag Gruppen zu machen die über mehr als eine Instanz laufen (FEP-2100 und FEP-d36d konnte ich finden). Es ist aber noch keiner angenommen und es hat auch niemand eingebaut.

Egal ob das Rechenzentrum brennt. Im Urlaub existiere ich nicht für die Arbeit und umgekehrt. Ich gehe da nicht ran.

Wenn der Urlaub beginnt hört die Arbeitsstelle temporär auf zu existieren. Du hast einen gesetzlichen Anspruch darauf im Urlaub nicht erreichbar zu sein.

Du hast recht aber bei Digital ist der Unterschied normalereise zwischen geht und geht nicht. Ein analoges Audiokabel kann die Qualität verändern indem es Frequenzen filtert.

Bei analogen Verbindung kann die Qualität was ausmachen. Bei HDMI oder ähnlichen natürlich nicht.

There is a whole field, that looks a bit like religion to me, about how to test right.

I can tell you from experience that testing is a tool that can give confidence. There are a few new tools that can help. Mutation testing is one I know that can find bad tests.

Integration tests can help find the most egregious errors that make your application crash.

Not every getter needs a test but using unit tests while developing a feature can even save time because you don’t have to start the app and get to the point where the change happens and test by hand.

A review can find some errors but human brains are not compilers it is hard to miss errors and the more you add to a review the easier it can get lost. The reviews can mostly help make sure that the code is more in line with the times style and that more than one person knows about the changes.

You can’t find all mistakes all the time. That’s why it is very important to have a strategy to avert the worse and revert errors. If you develop a web app: backups, rolling deployments, revert procedures. And make sure everyone know how and try it at least once. These procedures can fail. Refine them trough failure.

That is my experience from working in the field for a while. No tests is bad. Too many tests is a hassle. There will always be errors. Be prepared.

An adequate test coverage should help you with these kinds of errors. Your tests should at least somehow fail if you make something incompatible. Also using the tools of your IDE will help you with refactoring.

Mir ist auch schon aufgefallen, dass linke Bewegungen immer alle Probleme gleichzeitig behandeln wollen. Gerade bei den Demos gegen Rechts ist mir immer mal wieder aufgefallen, wie bestimmte Gruppen ihre Thema auch noch hinzufügen wollen. Das ist ein Problem wenn es leute abschreckt oder ausschließt. Es ist manchmal okay wenn man sich nur um ein linkes Thema kümmert.

Godmode: you maintain the fork.

But I want something else.

This one might save power because it will only dry as long as it needs to.

This feels very true

You don’t understand: it is not good if something is popular. Then there are people outside my bubble and they ruin it.
