“Every server can run every service.”
We designed and built Cloudflare’s network to be able to grow capacity quickly and inexpensively; to allow every server, in every city, to run every service; and to allow us to shift customers and traffic across our network efficiently. We deploy standard, commodity hardware, and our product developers and customers do not need to worry about the underlying servers. Our software automatically manages the deployment and execution of our developers’ code and our customers’ code across our network. Since we manage the execution and prioritization of code running across our network, we are both able to optimize the performance of our highest tier customers and effectively leverage idle capacity across our network.
An alternative approach might have been to run several fragmented networks with specialized servers designed to run specific features, such as the Firewall, DDoS protection or Workers. However, we believe that approach would have resulted in wasted idle resources and given us less flexibility to build new software or adopt the newest available hardware. And a single optimization target means we can provide security and performance at the same time.
We use Anycast to route a web request to the Continue reading

Imagine you followed the steps taken by Anne Baretta and stored network inventory into a database. What could you do with that information (apart from creating reports)? How about adding a web UI to help less-skilled network operators perform automated tasks?

AnyLog: a grand unification of the Internet of Things, Abadi et al., CIDR’20
The Web provides decentralised publishing and direct access to unstructured data (searching / querying that data has turned out to be a pretty centralised affair in practice though). AnyLog wants to do for structured (relational) data what the Web has done for unstructured data, with coordinators playing the role of search engines. A key challenge for a web of structured data is that it’s harder to see how it can be supported by advertising, so AnyLog needs a different incentive scheme. This comes in the form of micropayments. Micropayments require an environment of trust, and in a decentralised context that leads us to blockchains.
There have been several efforts to create a version of the WWW for "structured" data, such as the Semantic Web and Freebase. Our approach differs substantially by (1) providing economic incentives for data to be contributed and integrated into existing schemas, (2) offering a SQL interface instead of graph based approaches, (3) including the computational and storage infrastructure in the architectural vision.
Note that AnyLog also differs from projects such as DeepDive or Google’s Knowledge Graph. These aim at extracting Continue reading
It’s been almost 10 years since my previous post about
this. And 20 years since 2000-02-24, which is when arping 0.1
was released. It was a 208 line C file, with a hand made Makefile.
As of today when Arping 2.21 is overdue to be released, the code in
.c and .h files (excluding tests) is 3863 lines, and it uses the
amazing autotools framework for analyzing dependencies.
I’ve recently had the displeasure of working with cmake, which is
just the worst. Why anyone would think cmake is even remotely
acceptable I’ll never understand.
But the Arping story continues. It isn’t getting many new major features. Still, since the last post there’s been 205 commits, and 10 releases.
Things like:
gettimeofday() to clock_gettime(), when
available. More info about that in this blog post.uid=0 and stop. Capabilities can come in other wayspoll() to select() to work around bug in MacOS Xgetifaddrs() to resolve interfacesThe event might not be happening, but that doesn't mean we are going to ignore the big trends we...
Hello my friend,
We continue discussion about the variable in the Python, which we have started in the previous article. Today we cover new type, which is very useful and, therefore, widely used. In various programming languages, this type is known under various names. So, who is here?
Don’t wait to be kicked out of IT business. Join our network automation training to secure your job in future. Come to NetDevOps side.
How does the training differ from this blog post series? Here you get the basics and learn some programming concepts in general, whereas in the training you get comprehensive set of knowledge with the detailed examples how to use Python for the network and IT automation. You need both.
Answering to the question in the end of the preamble, here is the list. It is also known under the name array; however, in the Python’s terminology list is the correct term. The list variable contains any amount of the elements (starting from zero), which are siblings to each other, and they can be of any type as described in the previous article. Continue reading

What is LORA – Best reference – https://www.thethingsnetwork.org
I will anyways attempt to define this as a newbie who just got into this technology
“with the help of a specific Receiver and Transmitter and using Radio waves you can send small bits of information to long ranges without the need of repeaters or wireless IP networking gear. “
Why is this useful – I have many use cases simple one being measuring soil moisture for plants and measuring water level in an overhead tank.
I currently have a very expensive setup of a Raspberry Pi zero wireless, a Repeater to repeat my Base Ip Network and a solar panel to power the power-hungry sensor as Raspberry pi does not know how to go into Deepsleep and wakeup.
Lora Makes it simple and even in reasonable living space, wireless routers do not perform well to cover the range up till the back yard garden.
What do you need – Listed in the below article and its nicely written
Most of the Sample Code – https://randomnerdtutorials.com/ttgo-lora32-sx1276-arduino-ide/
I have tested its range till 300m without any issues at all, that’s like 4 times what my wireless router can do!
