an old colleague of mine work on a project bringing internet to rural communities in east Africa. his reasoning about network usability were always useful, especially considering jitter and latency. also, it is surprising how usuable some i

mind you that VM constraints are not to same as physical CPU contention and in some cases, this could be a bad test. (although unlikely for web developers).

this is basically what the openbsd community as done with several protocols/systems. LibreSSL is a complete rewrite of the openssl functionality with drastically fewer features. Same goes for CARP. Maybe running software with minimal d

heck, inter-as MPLS is also possible. While it requires cooperation from both sides, carriering RSVP-TE signals across autonomous systems is definitely possible.

it requires an override anyways in case of emergencies like a fire.

well, atleast you have the agency to do something about it yourself. also, building access systems should be hosted in the building they reside in for security reasons anyways.

but powershell is absolutely wonderful if you are running a windows environment. the fact that it is also able to use aspects of .NET is really, really useful.

Are decentralised protocols really more reliable? I highly doubt it. The reason the dollar is so strong is because it is backed by a goverment which will use its power to guarantee the dollar does not collapse. The same goes for the Euro,

yes, but this does not scale if you want to build residential connectivity. GPON makes this scalable and affordable, but at the cost of technical complexity. Fiber (as in, the cables themselves) is far cheaper to produce compared to copper

by kazen44 5y ago
Also, sending a singal across fiber is definitely not easy. ADSL is basically modulating a radio wave over a cable directly to another device. Fiber requires high quality optics, high quality lasers, tons of active hardware if you want to d

also, the infra (which ADSL runs on) was build in a time when telephone companies used to be either state-owned or a single monopoly with heavy goverment involvement. Doing the same thing with fiber is necessary, but will not happen without

to be fair, there is very little reason why shopify or stripe couldn't run on a couple of racks of servers in a couple of datacenters across the globe.

this happens lower down the stack too. Distributed redundancy is a good example. There are very, very few situation in which this couldn't be resolved with a simple BGP daemon on a server and anycast.

beancounters are not in charge of the direction of the company. In a lot of cases, it makes a ton of sense to go for capex vs opex. My old employer had a strategy which basically boiled down to owning everything inside this company expect f

Because DNSSEC is not just used for web stuff, in comparison to TLS certificates?
290.
by kazen44 5y ago
One of the advantages of DNSSEC, is that it allows you to use DNS as a secure validator for things like public ssh keys (SSHFP records), CA/TLSA records and other data which needs integrity.

the issue i have with this argument, is that it makes healthcare for those who are not in a privileged non existant. (with the boatload of social issues that come with it). Sure, you might get proper and very good healthcare, but what about

which is why the LIR's exist. you can get provider independant IP space from a LIR.

Mind you though, prior to the 1980's, most housing in (western) europe was either socially or state owned. Mainly because housing was build as a solution to the mass housing crisis after world war 2.

a ton of routers (think, high end access or core platforms) use "unroutable" ip space for internal communication between different systems in the router. These are hardcoded addresses used in the backplane of the system, and chang

protecting ipv6 Networks works just the same as ipv4 networks. by using firewalling. NAT is not a security mechanism. most consumer routers seem to block any incoming traffic from the outside world by default anyways.

RFC's an BCP's are worth following aswell. especially if one wants to know how systems in the default free zone are build.
