Passing messages

TRAIN ORDER HOOPSFor much of the twentieth century, train order poles were the most common, and certainly the most essential tools housed in any train station. As it was completely impractical for every passing train to stop for messages, the poles were a simple way to pass on orders and return messages to the station.The hoop on the top (above) is a bamboo pole, made from a single piece of wood that was heated and bent around a cylindrical object. Orders were attached within this hoop and the pole was then held up to a passing train. The crewman on the passing train would stick out his arm and “catch” the hoop with his whole arm. After pulling off the order, message, list, or waybill, the hoop was then tossed off the train and the stationmaster, or telegraph operator, would then have to trek along the track to recover the pole and, occasionally, a returned message. Standing beside the tracks and holding a bamboo hoop for a steam train was a risky and messy business. Steam trains were notorious for spraying hoop operators, and were generally dirty machines. Bamboo hoops were eventually replaced by “Y” or string hoops (shown above, bottom). This didn’t really solve anything for the hoop operators, as they still had to stand and hold the “hoop” for the train. The one major difference was that only the string that closed the hoop was taken onto the train and the pole was left in the hands of the stationmaster. Today, orders are relayed to trains using modern electronic technology, and the art of passing messages with a hoop is mostly forgotten.Both hoops were on loan this past summer from Jim Harte of McBride. They were displayed in the stationmaster’s office at the restored Dunster train station. Visit

Use the posted data to update the chart.The full main thread code is available in this CodePen.Web Worker ThreadNow inside worker.js we can poll the prices and post messages back to main thread:// CoinDesk BPI endpointconst apiUrl = ‘ Initialize prices let prices = {}; // Poll prices setInterval(async () => { // Fetch latest data const res = await fetch(apiUrl); prices = await res.json(); // Post back to main thread self.postMessage(prices);}, 3000); // 3sec intervalWe use setInterval to poll the API every few seconds, then post the updated prices back to the main thread.The full worker script code is available here.And that‘s it! Together the main thread and worker script coordinate to fetch data and update the UI without blocking.Here is a CodePen showing the full demo: See the Pen Web Worker Demo: Fetching API Data by Aravind (@aravindballa) on CodePen.Hopefully this gives a real-world example of leveraging web workers! 😊Communicating Between ThreadsAs seen above, the primary way for web workers to communicate with the main thread is by posting messages to each other.The main interface for this in both contexts is the postMessage() method. Along with the message content, you can specify message origins and transferrable objects.Some key mechanisms for thread communication:Main Thread -> Workerworker.postMessage(): Send message to worker worker.onmessage: Listen for messages from workerWorker Thread -> Main Thread self.postMessage(): Post messages back to main threadself.onmessage: Listen for messages from main threadAdditionally, web workers expose mechanisms like terminate() to end threads and handle errors.This abstracted message-passing approach allows you to coordinate between threads without worrying about low-level concurrency issues.Browser SupportMost major browsers have excellent support for web workers:However, some limitations exist:IE10 and below do not support web workers at all Safari support is more recent For cases when web workers are not supported, you can fallback to using Web Worker polyfills. Some popular options:WorkerizeWeb Worker ThreadsThese polyfills emulate worker threads by spawned separate processes. This ensures backwards capability while limiting concurrency.Performance ConsiderationsWhile web workers are quite useful, some care should be taken to use them efficiently: Memory overheads – Each worker has its own global context, so memory usage can add upThread contention – Creating too many workers could contend for limited browser threads Message passing costs – Serializing excessive large data back-and-forth has a costSome best practices include:Keep the number of active web workers reasonable (under 10)Pool/reuse workers instead of continuously creating new ones Pass small message data instead of entire huge objectsUse Comlink for optimized message passing Additionally, you should not use web workers for any browser-specific APIs like DOM manipulation, as they are not exposed to worker contexts.Common Use CasesHere are some common examples where web workers shine:Processing large local datasets (JSON, CSV, etc) Polling and streaming external APIsRunning expensive computations like image filters Periodic background syncs with serverPrefetching assets/data for later use Parsing multimedia files (audio, video, images)Spellchecking/grammar validation Essentially any CPU or I/O intensive tasks that could block the main UI thread are good fits for delegation to a web worker.ConclusionI hope this

The anniversary of someone’s passing is a hard time for all who knew them. Sometimes the pain of loss fades and an anniversary can bring it all back very quickly. Others like to use an anniversary to remember the passing of someone, perhaps visiting their grave and laying flowers. Often it is supportive to send a card on the anniversary of someone’s death to let them know you are also thinking of them.The most special people in our lives – fathers, mothers, brothers, sisters etc. – leave behind such strong memories that it is impossible to forget them. So commemorate their lives and remember them on the anniversary of their passing.If you are struggling with what to say in a card for the anniversary of someone’s death, or you want to write a message and celebrate the passing of someone special from your own life, use the quotes and messages below.Death Anniversary QuotesOne Year Death Anniversary QuotesDeath Anniversary MessagesFor FatherFor MotherFor BrotherFor SisterFor FriendsThese quotes are both an insightful and touching take on death and its impact on people. They can be used in an anniversary card for someone’s passing or on social media like Facebook to let someone know you are thinking of them on what will be a tough day.“In your life you touched so many, in your death many lives were changed” – Melinda Jones“Perhaps they are not the stars, but rather openings in Heaven where the love of our lost ones pours through and shines down
