A cartoon intro to WebAssembly (2017)

  • WebAssembly is a way of taking code written in programming languages other than JavaScript and running that code in the browser.
  • So when people say that WebAssembly is fast, what they are comparing it to is JavaScript.
  • Multiple browsers added just-in-time compilers, also called JITs. As JavaScript was running, the JIT could see patterns and make the code run faster based on those patterns.
  • The introduction of these JITs led to an inflection point in the performance of JavaScript.
  • With this improved performance, JavaScript started being used for things no one ever expected it to be used for, like server-side programming with Node.js.
  • The performance improvement made it feasible to use JavaScript on a whole new class of problems.
  • So, let’s dive into the details to understand what makes WebAssembly fast.

How to Decode Modbus Protocol

  • Modbus is a protocol designed to allow communication between network-attached serial devices or applications.
  • Modbus networks are usually configured with one Master device which can be communicating and receiving responses with from 1 to 247 Slave devices.
  • The Modbus protocol is used extensively in industrial automation implementations, enacting communication between the many sensors and controllers that make up such systems.
  • The ability to decode and understand the messages generated by the protocol are the primary means of troubleshooting problems encountered with the Modbus network or its connected devices.
  • The decoding process performs a conversion of the message format used by the Modbus serial devices into information which can be understood by human system administrators.
  • A high-quality Modbus message decoder is an essential tool for individuals working with networks or devices that use the Modbus protocol.

Senate to vote on competing proposals to reopen government -- but still no end in sight to shutdown

  • Washington (CNN) - The Senate is set to hold a pair of test votes on competing proposals to reopen the government on Thursday -- and both are expected to fail with no clear consensus between Democrats and Republicans over how to end the longest shutdown in US history.
  • First up will be a vote on a Republican-backed proposal that would allocate $5.7 billion for President Donald Trump's long-promised border wall.
  • The decision to allow votes on measures that are not certain to receive the bipartisan support needed to pass Congress and be signed into law by the President marks a shift for McConnell, who had previously said repeatedly after the shutdown started that he would not take up legislation related to the funding impasse unless it was clear it would be able to pass Congress and be signed into law by the President.

CNN Poll of Polls: Trump approval takes a hit mid-shutdown

  • CBS News released a poll Wednesday showing Trump with 36% approval, his lowest of all polls this month.
  • With Trump's approval on the downswing, the polls are also showing people blame him for the shutdown; in each of the four polls that asked respondents to place blame, majorities said blame lies with the President, while about a third in each poll cited Democrats in Congress as primarily responsible.
  • Half in the CBS News poll said that they want Democrats in Congress to agree to a budget that includes wall funding and two-thirds want Trump to agree to the budget without the wall.
  • Perhaps the worst news for the President, around half said that Pelosi is doing a better job handling negotiations over the partial shutdown than Trump (35% in the CBS News poll said he's doing a better job).
