Is there any open source FPE implementation available? I am no cryptography expert but I am aware of the basic concepts behind FPE and I am looking for a generic library which helps me implement FPE for sensitive data such as phone numbers, social security numbers, etc. No strong programming language preference, but robustness of the algorithm and implementation are important.
What I found so far:
libffx (implements FFX in Python, GPL license)
botan (implements FE1 in C++, BSD2 license)
Miracl (implements BPS in C/C++, dual licensing: commercial or AGPL)
but I did not yet personally use them.
Are there any other libraries supporting FPE, or will be in the near future? Which of these or others are recommended and why?

Simple and extendable library on Python https://github.com/emulbreh/pyffx

I‘m a new to clickhouse, and already read "druid vs clickhouse", but still don't know which situation can use clickhouse. I know they are good OLAP engines。
Druid is an excellent timing database。 At large data scale, it can provide ad-hoc aggregate queries,clickhouse too;
They have similar disadvantages, such as slow data writing。
Which engine should I do with OLAP?
This is the great article https://leventov.medium.com/comparison-of-the-open-source-olap-systems-for-big-data-clickhouse-druid-and-pinot-8e042a5ed1c7
Either your organization should have engineers who are able to read, understand and modify the source code of the chosen system, and have capacity to do that. Note that ClickHouse is written in C++, Druid and Pinot — in Java.

I have a basic question. For microcontroller project , we need a compiler which support that specific microcontroller. But if compiler does not support a specific microcontroller then what does it mean? In other words ''Compiler support this microcontroller '' what it means? Any detailed description will be appreciated.
Thanks
The compiler transforms high level source code into lower level assembly instructions. Different families of CPU cores use different assembly instruction sets. For example, the Intel x86 instruction set is different from the ARM instruction set. A compiler that doesn't support a specific microcontroller cannot transform source code into that microcontroller's assembly instruction set.

I need have a networking monitoring system that have these feature.
opensourced (must)
written by c/c++. (must)
async io mode (like io, must)
support ping, http, snmp, mysql, redis... protocal
The System must run with epoll mode so that run many test as there can, no blocking at all.
Is there any avaliable one?
I don't know if you looked on sourceforge for open source software, they have many rated network monitoring systems written in C and C++. Pandora is good but look around maybe you might find what you looking for there.>>> Link<<<

I'm starting a new job soon with a manufacturer and supplier of fibre-optic multiplexers. I'm not expected to be a techie, but can anyone recommend some books on networking (not necessarily just optical) that would give me a good foundation. My current networking knowledge is minimal.
For a basic introduction to the internet and the full-stack of technologies... Take a look at Stevens' TCP/IP Illustrated, Vol I or Doug Comer's Internetworking with TCP/IP, Vol I. You should be able to find either one in your public library...
For cabling and network technician's books:
Comprehensive cabling info: Oliviero and Woodward's Cabling: The Complete Guide to Copper and Fiber-Optic Networking
In-depth coverage of ethernet (80% of what you'll probably be cabling): Spurgeon's Ethernet: The Definitive Guide
Advanced troubleshooting (including some protocol troubleshooting): Neal Allen's Network Maintenance and Troubleshooting Guide: Field Tested Solutions for Everyday Problems

I'm looking for an open-source framework for classified ads. It needs to be .NET-based, but I can pay.
Advanced features not really required - just need to be able to post ads for registered users in a private environment.
In terms of price, anything up to $1,000 is fine.
Does anyone have any suggestions?
MixNP is written in ASP.net C# and is a new addition to codeplex. It is free and open source GPLv3.
Looks good.

Microsoft have a starter kit for classifieds:

I'd think DotNetNuke would work for you, although it might be a bit of overkill for your intended use case.
