海外TECH	DEV Community	Top 13 open source APM tools in 2021	https://dev.to/signoz/top-13-open-source-apm-tools-in-2021-1g4n	Top open source APM tools in Businesses are embracing digital transformation now more than ever In most cases the digital channel is the primary driver of revenue and growth Customers and end users are going online to fulfill both their daily and long term needs The digital shift has made the app production environment a critical piece of an organization s success The performance of your application in production needs to be monitored to ensure high availability at all times Not only that but organizations also need to monitor any latency issues in serving user s requests As they say Slow is the new down in today s competitive digital landscape This has led to the birth of a number of application performance monitoring tools Open source APM tools have added benefits over their SaaS counterparts as the source code is available to your org s developers Benefits of Open Source APM tool over SaaS APM tools Customization You can customize the tool s source code to suit your needs Self hosting You don t need to send your data outside your environment With privacy laws becoming more stringent this might be the future of APM tools Developer First Your org s developers can look under the hood of an open source APM tool They can decide for themselves whether the tool meets their requirements or not Community support Open source tools have active communities around them Communities ensure code accountability and support You can directly influence a product s roadmap by raising GitHub issues But first let s understand what is application performance monitoring and why is it needed What is application performance monitoring APM Application performance monitoring is the process of keeping your app s health in check APM tools enable you to be proactive about meeting the demands of your customers Why is application performance monitoring APM needed A robust APM tool can provide your engineering teams the much needed visibility and context into the inner workings of your application Modern distributed systems have enabled scale at a global scale but at the same time have increased the complexity of an application A few essential APM benefits in solving performance issues are as follows Gives a centralized context and visibility into the app s inner workings across a distributed systemAllows you to proactively identify issues that can cause breakdown and solves latency issuesHelps you to meet end user expectations and demandsIncrease revenue by protecting against downtime and user churnSaves engineering bandwidth in debugging and troubleshootingList of top open source APM tools in

the first neuralthe implant that will let youcontrol a computer or mobiledevice anywhere you go NeuralinkMAIN POINTS BMI stands for Brain Machine Interface BMI is simply a way for a computer to communicate with the brain using a chip Neuralink is an American company that is involved in building advanced Brain Machine Interfacetechnology The Neuralink chip is put into the brain using an automated precision robot so it is extremely safe Neuralink puts a chip in your brain so it can efficiently monitor waves generated by your brain Neuralink has an app that allows you to manipulate your phone using your brain by thinking about it Technology is nothing but a tool and the results it gives us are just a result of what their users which so the technology itself is not bad but instead the persons using them are LET S READ We ve all probably watched movies like Matrix Terminator and I robot where there s always a crazy smart guy who creates a smart computer and then eventually can t control it anymore and then the robot sees humans and decides the best way to solve that problem would be to kill every human on earth like that will ever work but then luckily there comes some ordinary guy whose life is suckish at the beginning of the movie but then suddenly the ordinary guy amazingly gets to know that computers want to kill humans and he has the responsibility to save the world and so with some trepidation he goes after the robots with a suckish plan but he almost fails because of the suckish plan or whatever and the robots almost win but then the hero discovers his inner strength and then is able to save the world and he gets to kiss the hot girl lucky dude he would never have been able to kiss if he was still the ordinary and then the movie ends with the guy becoming more sure of himself and well his life changes and all this happens within hrs cool huh Well these days the stuff we only thought happened in movies are happening in real life from self driving cars robot dogs to Siri Google Assistant and generally AI and well let s be honest we re all scared that our devices are going to come after us someday the same way they do in the movies I mean after terminator who wouldn t But I m hoping that after reading all this you ll know your technology will not kill you and I ll be doing that with something called BMIs But first WHAT IS A BMIBMI is an acronym that stands for Brain Machine Interface also Known as Brain Computer Interface BCI According to Wikipedia Brain Machine Interface BMI Is a direct communication pathway between an enhanced or wired brain and an external device In simple words BMIs are simply a machine s ability to talk to and understand commands from the human brain due to a connection between the two of them In other words it simply the ability to talk to your computer using your brain Now we are going to talk about a very popular BMI company Neuralink what they do how they do what they do and why But first WHAT IS NEURALINKNeuralink is an American BMI company that means they create Brain Machine Interface systems The company was made popular because of its association with Elon Musk Yup the billionaire Elon Musk According to the company s website Neuralink is a team of exceptionally talented people who are creating the future of brain Interfaces Before we see all the cool stuff Neuralink does let s first seeHOW THE BRAIN WORKS The brain is made up of nerve cells called neurons which are responsible for processing thought There are many types of neurons but all neurons generally have parts Dendrites Soma and Axon The dendrite is responsible for receiving electrical signals The Soma is responsible for computing Processing electrical Signal The Axon is responsible for passing out computed electrical signals to the next Dendrite in the chain The brain communicates information through the use of electrical signals The brain is made up of billion neurons and when processing a particular event Action Potential it uses a chain of neurons to process events For instance when you see a car coming towards you your eyes immediately send electrical signals to your brain through the optical nerve and then the brain forms a chain of neurons to make sense of the incoming signal and so the first neuron in the chain collects the signal through its Dendrites and sends it to the Soma to process the signal after the Soma finishes with its task it sends the signal to the Axon which then sends it to the Dendrite of the next neurone in the chain the connection between Axons and Dendrites when passing on information is called a Synapse So the entire process continues until the brain finds a Sapiotemporal Synaptic Input that s scientific Lingo for the brain continues processing until it finds an optimal response to the signal sent to it and then it sends signals to the necessary effectors eg you re legs and then the brain sends a signal to your legs to run away from the oncoming car Now we have an idea of how the brain works let s get toWHY DOES NEURALINK WANT TO PUT A CHIP IN MY HEADNow you must understand that for Neuralink s BMI to work they don t actually need to put the chip into your head but it would make the BMI technology more effective putting a BMI outside the head is like watching a football game outside the stadium you d hear the noises from those inside the stadium and know when something good or happens but you wouldn t be able to know exactly how a player scored or missed So putting a chip into the human head is really for no other reason apart from the clarity it gives Because for the chip to be able to efficiently decode the electrical signals being used by the brain to communicate and then send to the computer it has to be able to receive the exact waves being generated by the brain and this cannot be achieved efficiently when the chip is placed outside the brain Now we know why Neuralink puts a chip inside our brain let s seeHOW NEURALINK PUTS THE CHIP INTO OUR BRAINThe electrode threads in the Neuralink chip AKA N chip are extremely small roughly millimetres in diameter so it is almost impossible for it to be surgically placed into the brain so the guys at Neuralink built an automated precision robot that surgically places the chip into the human brain Now you might be wondering how many chips you need to have in your brain a single neural link chip can cover up to brain cells and we have billions of brain cells so you do the math Well let s check our list we ve understood why neuralink has to put a chip in your head we ve gotten to understand how they put a chip in your head now the fun part we are going to talk aboutHOW THE CHIP IN YOUR HEAD ALLOWS YOU TO COMMUNICATE WITH YOUR COMPUTERThe Neuralink chip is placed into the parts of the brain that monitor movement the chip contains tiny fibre threads called neural threads and each small thread contains many electrodes and the electrodes are responsible for receiving electrical signals from the brain and then sending them to the chip and the chip then turns the electrical signals it receives into a binary that the computer can understand for instance if you have a neuralink chip implanted into you and you want to move your computer mouse cursor all you have to do is think about moving your arm and then your brain sends electrical signals to your hands and in the process the fibre threads in the N chip receive those signals using the electrodes and the chip then turns those electrical signals into binary and then sends the binary to your computer using a wireless connection and your computer mouse cursor The same thing happens when you want to charge your chip the charger is compact inductive That just means it can wirelessly detect your chip while it s in your head and so it wirelessly connects to your chip and charges in from the outside Now after all this you might be like okay this is all cool butWHAT DOES A CHIP IN THE HEAD HELP DOThe N chip will help humanity in a lot of ways picture for a moment that rippled man on the street that deaf and dumb guy or that blind guy who can t join WhatsApp Instagram Twitter or play video games simply because they can t operate a computer Well to put it simply Neuralink gives them that opportunity Despite all this I still know that they are some people out there who won t want a chip in their head I ll be honest I was too because they are scared and they want to knowHOW SAFE IS THE TECHNOLOGYFrom the beginning of time man has misused technology from guns ships to planes and cars but that hasn t stopped us from using technology has it some people use guns to defend themselves while some use guns to rob others some people use aeroplanes to travel but others use it to commit genocide some people use smart phones to connect with friends and family while some people use it to plan criminal activities Now you might be thinking but those are small time crimes we are talking about the brain now Now I ask you this what is the difference between Neuralink today and the smart phone to your great grandfather Technology has always improved and people have always abused it but it is the people and not the technology which is evil and it is our responsibility as humans to fight against those who want to limit technology through their evil deeds don
