When a 25-year-old activist from Minsk who goes by Pavlo was detained by Belarusian KGB security forces last summer, he knew they would search his phone, looking for evidence of his involvement in anti-government protests.
The police officer asked for Pavlo’s password to Telegram, the most popular messenger app among Belarusian activists, which he gave him. The officer entered it and... found nothing. All secret chats and news channels had disappeared, and after a few minutes of questioning Pavlo was released.
Pavlo’s secret? A secure version of Telegram, developed by a hacktivist group from Belarus called the Cyber Partisans. Partisan Telegram, or P-Telegram, automatically deletes pre-selected chats when someone enters the so-called SOS password.
... after entering a fake [SOS] password, P-Telegram can automatically log out of the account, delete selected chats and channels, and even send a notification about the arrest of the account owners to their friends or families.
P-Telegram also allows other activists to remotely activate the SOS password on the detainee’s phone. For this, they need to send a code word to any of the shared Telegram chats.
Another feature on P-Telegram automatically takes photos of law enforcement officers on the front camera when they enter a fake password. “We warn users that this can be dangerous, as this photo will be stored on the phone, revealing that a person may use Partisan Telegram,” Shemetovets said.
Cyber Partisans are constantly updating their app, fixing bugs, and adding new features. They also regularly conduct independent audits to ensure that P-Telegram complies with all security measures.
A recent audit by Open Technology Fund’s Red Team Lab proved that it is almost impossible for “casual observers without technical knowledge and specialized equipment” to identify the existence of P-Telegram on a device.

The EU wants to oblige providers to search all private chats, messages, and emails automatically for suspicious content – generally and indiscriminately. The stated aim: To prosecute child pornography. The result: Mass surveillance by means of fully automated real-time messaging and chat control and the end of secrecy of digital correspondence.
Other consequences of the proposal are ineffective network blocking, screening of person cloud storage including private photos, mandatory age verification leading to the end of anonymous communication, censorship in Appstores and the paternalism and exclusion of minors in the digital world.

jmAs I’ll explain, messenger apps’ apparent success in fulfilling such a surprising array of tasks does not owe to the triumph of “conversational UI.” What they’ve achieved can be much more instructively framed as an adept exploitation of Silicon Valley phone OS makers’ growing failure to fully serve users’ needs, particularly in other parts of the world. Chat apps have responded by evolving into “meta-platforms.” Many of the platform-like aspects they’ve taken on to plaster over gaps in the OS actually have little to do with the core chat functionality. Not only is “conversational UI” a red herring, but as we look more closely, we’ll even see places where conversational UI has breached its limits and broken down.

As she said that, I remembered that indeed, this was once very confusing, but then I got used to it.

http://blog.confluent.io/2015/03/25/a-comprehensive-open-source-rest-proxy-for-kafka/
jmThe REST Proxy is an open source HTTP-based proxy for your Kafka cluster. The API supports many interactions with your cluster, including producing and consuming messages and accessing cluster metadata such as the set of topics and mapping of partitions to brokers. Just as with Kafka, it can work with arbitrary binary data, but also includes first-class support for Avro and integrates well with Confluent’s Schema Registry. And it is scalable, designed to be deployed in clusters and work with a variety of load balancing solutions.
We built the REST Proxy first and foremost to meet the growing demands of many organizations that want to use Kafka, but also want more freedom to select languages beyond those for which stable native clients exist today. However, it also includes functionality beyond traditional clients, making it useful for building tools for managing your Kafka cluster. See the documentation for a more detailed description of the included features.

http://mechanical-sympathy.blogspot.co.uk/2014/05/simple-binary-encoding.html
jman OSI layer 6 presentation for encoding/decoding messages in binary format to support low-latency applications. [...] SBE follows a number of design principles to achieve this goal. By adhering to these design principles sometimes means features available in other codecs will not being offered. For example, many codecs allow strings to be encoded at any field position in a message; SBE only allows variable length fields, such as strings, as fields grouped at the end of a message.
The SBE reference implementation consists of a compiler that takes a message schema as input and then generates language specific stubs. The stubs are used to directly encode and decode messages from buffers. The SBE tool can also generate a binary representation of the schema that can be used for the on-the-fly decoding of messages in a dynamic environment, such as for a log viewer or network sniffer.
The design principles drive the implementation of a codec that ensures messages are streamed through memory without backtracking, copying, or unnecessary allocation. Memory access patterns should not be underestimated in the design of a high-performance application. Low-latency systems in any language especially need to consider all allocation to avoid the resulting issues in reclamation. This applies for both managed runtime and native languages. SBE is totally allocation free in all three language implementations.
The end result of applying these design principles is a codec that has ~25X greater throughput than Google Protocol Buffers (GPB) with very low and predictable latency. This has been observed in micro-benchmarks and real-world application use. A typical market data message can be encoded, or decoded, in ~25ns compared to ~1000ns for the same message with GPB on the same hardware. XML and FIX tag value messages are orders of magnitude slower again.
The sweet spot for SBE is as a codec for structured data that is mostly fixed size fields which are numbers, bitsets, enums, and arrays. While it does work for strings and blobs, many my find some of the restrictions a usability issue. These users would be better off with another codec more suited to string encoding.

jman ultra low latency, high throughput, persisted, messaging and event driven in memory database. The typical latency is as low as 80 nano-seconds and supports throughputs of 5-20 million messages/record updates per second.
This library also supports distributed, durable, observable collections (Map, List, Set) The performance depends on the data structures used, but simple data structures can achieve throughputs of 5 million elements or key/value pairs in batches (eg addAll or putAll) and 500K elements or key/values per second when added/updated/removed individually.
It uses almost no heap, trivial GC impact, can be much larger than your physical memory size (only limited by the size of your disk) and can be shared between processes with better than 1/10th latency of using Sockets over loopback. It can change the way you design your system because it allows you to have independent processes which can be running or not at the same time (as no messages are lost) This is useful for restarting services and testing your services from canned data. e.g. like sub-microsecond durable messaging. You can attach any number of readers, including tools to see the exact state of the data externally.
