海外TECH	DEV Community	What is the Cloud?	https://dev.to/aspittel/what-is-the-cloud-1n65	What is the Cloud Frontend developers Have you ever wondered why to choose a certain type of database for a project how to create an API how to deploy to AWS or what a container is You re in the right place This series will teach you all about backend development specifically targeted at frontend developers you know how to code you may have heard certain backend terminology but you don t consider yourself fullstack You ll learn backend concepts and how to implement them using AWS In this first post of the series we ll start off by defining what the backend is what difficulties there are within backend development and then we ll discuss what the cloud is and how it relates to backend development What is Backend Development Traditionally the definition for a frontend vs backend developer is that frontend developers work on the client side they build the interface that users interact with Backend developers work on server side code That can include building APIs database interaction and dealing with server configuration I started my career as a backend developer working mostly on building data science systems I had to think a lot about scalability how to handle and analyze large amounts of data and how to deploy those systems in dependable ways Some of the questions a backend developer may have to answer include How do you scale a system for a million users More than a million How much data needs to be stored How fast does it need to be accessed Are there long running jobs that need to be managed There are so many trade offs that must be weighed when building these systems We ll talk about a bunch of them in this series One big evolution in backend development is the cloud though it s impacting almost everyone online not just backend devs What is the Cloud The cloud allows you to access computer resources on demand You may have used Google Drive or iCloud to store your files online rather than your own computer or phone wo that you have more storage space This is a perfect example of how the cloud is used Many companies also use the cloud for their server infrastructure You ve probably heard of servers before they re essentially computers that send information to other computers We use them to handle the request response cycle for websites they take a request and based on it handle business logic database queries etc and then send a response back to the client In comes data centers these hold all the needed servers for a company and they buy more and more servers as the company grows They would have staff to manage the data center and they d need to install software on and maintain the servers yourself The cloud allows you to access the provider s servers and use them instead of needing to manage the data centers yourself This provides a lot of benefits to the company first you only need to pay for what you use instead of all the servers you buy for a data center You also have global availability with most cloud providers you don t need to have data centers all over the world to speed up your response time globally the cloud provider does that for you And you don t need to pay for the data centers or data center staff yourself instead that s done by the cloud provider AWS has a whitepaper explaining these benefits in further detail There are different families of cloud services Infrastructure as a service IaaS is the lowest level where you have more control over the operating system and runtime for your services Examples include Amazon EC and Digital Ocean Platform as a service PaaS provides cloud components where you manage the application logic and data but not the servers or anything low level Examples include Heroku and AWS Elastic Beanstock Software as a service SaaS cloud services an end user directly uses with no cloud management needed Some examples include Dropbox iCloud and Slack Function as a service FaaS allows you to deploy just a function into the cloud you don t need to do server management or anything like that AWS Lambda is a great example of this On that note AWS or Amazon Web Services is a cloud provider and my employer who has over different cloud services We ll be chatting about a bunch of these services throughout this series ConclusionNext time we ll go a little deeper into the logistics of using the cloud How can you set up an AWS account with a billing alarm and an IAM user If you have topics you d like to see answered in this series please let me know in the comments or via twitter	2021-11-02 14:26:53
海外TECH	DEV Community	DevOps for dummies	https://dev.to/abhirajb/devops-for-dummies-159i	DevOps for dummiesYou ll hear the word DevOps everywhere these days DevOps may appear to be a rather simple concept at first glance Isn t the term DevOps merely a mix of Dev and Ops Yes of course But let s go a little deeper into that DevOps is at its core about bringing together historically different functional domains much like the phrase itself It entails bridging the gap between software development Dev and IT operations Ops teams or removing silos between them with the goal of releasing software faster and more reliably However since its inception roughly a decade ago DevOps has become a catchall term for any and all trends in software development and IT operations It s understandable given that DevOps is still expanding covers a wide range of topics and is changed and accepted based on a company s individual business objectives priorities and current knowledge base We ll attempt to present our own principle based description of what DevOps is at the end of this article but before we do it s helpful to explore what DevOps is NOT debunking some of the prevalent misconceptions about DevOps The ultimate goal of DevOps is to decrease the duration of the system s development life cycle while delivering features fixes and updates frequently in close synchronization with business objectives Before DevOps We had two approaches for software development namely the Waterfall and the Agile Waterfall ModelThis strategy begins with the gathering and analysis of requirements The first one these stages being Requirements This is the stage in which you obtain the client s requirements for constructing an application After that you try to figure out what these needs are The Design phase is the following step in which you create a software plan Here you consider how the software will appear in its final form Once the design is complete you can go on to the Implementation step where you will begin developing the programme The development team collaborates on several aspects of the application In the Verification step you test the application once it has been developed The application is subjected to a variety of tests including unit testing integration testing and performance testing Finally there s the phase of maintenance The application s performance is monitored throughout this period Agile MethodologyIn Agile a employer releases the software with a few excessive precedence functions within the first iteration After its launch the cease users or the customers give you comments approximately the overall performance of the application then you definitely make the essential adjustments to the software in conjunction with a few new capabilities and the software is again released which is the second one new release You repeat this complete method till you reap the preferred software program exceptionally Who is a DevOps Engineer DevOps Engineer is somebody who understands the Software Development Lifecycle and has the outright understanding of various automation tools for developing digital pipelines CI CD pipelines DevOps Engineer works with developers and the IT staff to oversee the code releases They are either developers who get interested in deployment and network operations or sysadmins who have a passion for scripting and coding and move into the development side where they can improve the planning of test and deployment Hope this post has been able to add value to your knowledge Until next time AbhirajIf you like my posts you can support me by buying me a coffee	2021-11-02 14:16:42

gadgets we d recommend when budget isn t an issue Apple TV KWill Lipman Photography for EngadgetWhile the latest Apple TV model isn t a massive leap over its predecessor there are a few updates that make it worthy of a holiday splurge The redesigned Siri remote is a big improvement over the previous version both app and streaming performance is quicker than ever and there s support for Dolby Atmos and Dolby Vision As always there s deep integration with iOS and HomeKit compatibility is a nice bonus And when you tire of music and movies the Apple TV also works as a gaming console with

projector at Amazon inch LG C OLED TVLGIf you re looking for the best possible TV to buy there s no question Pick an OLED model Personally I d stick with LG s C the latest generation of the company s astounding OLED screens Unlike LCD TVs which rely on backlights pixels on OLED TVs can turn themselves on and off individually That allows them to capture inky blacks and deliver better contrast than most LCD panels The C isn t much different from last year s CX line but it s LG s most evolved OLED yet It has a Hz refresh rate for speedy gaming as well as support for G SYNC and Freesync to avoid annoying frame stuttering Its wide viewing angles also mean everyone can get a perfect picture no matter where they re sitting ーDevindra Hardawar Senior EditorBuy inch LG C OLED TV at Amazon Monoprice Monolith THX Atmos home theater speakersMonoprice Sometimes a soundbar just doesn t cut it No matter how many drivers you can cram in or how good the virtual surround sound is nothing beats the immersion of a full home theater speaker setup Monoprice s Monolith series is one of the best options around It sports a powerful center channel your choice of towers or bookshelf speakers with upward firing Dolby Atmos drivers and subwoofers powerful enough to rattle your walls There are tons of surround sound systems to choose from but the beauty of the Monolith line is that it has all of the latest speaker tech and it s reasonably priced at least compared to other Hi Fi systems It used to be that you had to mix and match speakers to create an affordable surround setup You can start small with a few towers and a subwooferーand once you ve got a complete system you may never need to go to the cinema again ーD H Buy Monolith speakers at Monoprice starting at Optoma Cinemax POptoma With

easy fix as it has three HDMI ports ーS D Buy Optoma CinemaX P at Amazon Roku UltraWill Lipman Photography for EngadgetIf you re not a fan of the Apple TV the Roku Ultra is the only other set top box worth considering It s fast enough to stream K video with Dolby Vision and it supports just about every streaming app you d want It also has a solid remote with voice search capabilities and you can still access all of Apple s streaming video via the Apple TV app And while Roku s interface isn t pretty it s fast and gets the job done ーD H Buy Roku Ultra at Amazon Sonos ArcWill Lipman Photography for EngadgetSonos finally introduced an upgrade to its aging Playbar last summer when it debuted the Arc In addition to an updated design the soundbar also supports Dolby Atmos which makes it an excellent choice for the living room True to Sonos lineage the Arc is also well suited for music and you have the ability to add a subwoofer or satellite speakers as you see fit It will also function as part of a new or existing Sonos multi room setup and any time you add on to the main living room configuration the Arc automatically adjusts to compensate for the extra gear ーB S Buy Arc at Sonos Sony HT A soundbarSonySony s Atmos enabled soundbars are among the best and its most recent top end model is no different The A replaced the HT ST as the flagship in the company s lineup only this time the soundbar doesn t come with a wireless subwoofer in the box Instead Sony is offering you the ability to add to your home theater setup as needed The company offers two subwoofer options as well a pair of rear speakers The A on its own though is a channel unit equipped with HDMI with eARC plus both K and K Hz passthrough This means Dolby Atmos and Dolby Vision are both in play as well as ample support for gaming Plus wireless connectivity includes Chromecast AirPlay and Spotify Connect when you just need some tunes ーB S Buy Sony A at Crutchfield inch TCL Series smart TVWill Lipman

levels that are approaching what you d see from OLED The lower cost is the big selling point here though giving you enough leftover cash to invest in your sound system It s a solid entry both for movie watching and gaming The series also includes some of the cheapest K TVs on the market though we d recommend holding out on K until more content is actually available Something that may take a long while ーD H Buy inch TCL Series TV at Amazon Valencia Theater Seating Verona seatsValencia Theater SeatingWhere your butt sits is just as important to your home theater as your screen and sound

海外TECH	Engadget	NVIDIA Broadcast is kinda underrated	https://www.engadget.com/nvidia-broadcast-is-kinda-underrated-141026195.html?src=rss	NVIDIA Broadcast is kinda underratedWhat if I told you that a graphics card could be the quickest way to improve your livestream or podcast audio It sounds counterintuitive but think about it A GPU often has an extreme amount of processing power sitting idle so why not use that redundant hardware for other things Fortunately NVIDIA is way ahead of us and has already harnessed the potential of its own GPUs to do things beyond well graphics For example you might remember RTX Voice which as the name implies is a tool for upping your microphone game Then it quietly released Broadcast ーa more comprehensive tool aimed squarely at streamers and content creators Both offer great audio enhancement features but we ll focus on Broadcast here as that has effectively though not entirely replaced RTX Voice Right up the top I should set some expectations While Broadcast offers some helpful tools for all streamers the real benefit is for those with more entry level gear For example if you have something like a Blue Yeti and an older webcam you re going to get more out of this tool than someone with a Shure SMB and a Sony A Broadcast specifically “uses Tensor Cores on NVIDIA RTX GPUs to accelerate AI calculations so you can game livestream and run AI networks at the same time It s compatible with any RTX GPU ー“GeForce RTX Quadro RTX or higher ーaccording to a company spokesperson If you don t already own a compatible GPU now isn t exactly the best time to be looking for one thanks to the ongoing chip shortage but things do seem to be slowly easing up If you do have a supported card then you can simply download the Broadcast app and get cracking The better news is if you have a Logitech headset or Blue mic as of today Broadcast is natively supported so you won t even need to dive into the app Supported models at launch are Logitech s G Pro X and Pro X Wireless headsets and Blue s Yeti X Yeti Classic and Yeti Nano microphones While that s only a fraction of the companies offerings it still represents a lot of headsets and microphones that today have new untapped potential NVIDIA James TrewThe Logitech partnership to date only works with some products and only with some of the features on offer in NVIDIA Broadcast Those looking for the full audio visual featureset will still need to download the standalone app Once you re in Broadcast you ll see three main tabs Microphone Speaker and Camera We ll focus mainly on the microphone section but the other two are just as useful and it all combines into one hub for tweaking your stream be it video audio or both Under the Microphone tab you ll find a drop down on the left to select your input source and a space below for adding effects The area on the right is given over to a tool for testing these effects before you commit to them Right now there are only two effects to choose from But both are useful and there s no novelty chaffe get your robot voices elsewhere Broadcast is focused on shaping up your stream not bending it into something else And importantly all in realtime unlike something like iZotope RX which is incredibly good at repairing sound but aimed at post production Audio toolsThe first effect is Room echo removal For anyone who has a space with less than favorable acoustics this is going to help you dial down that dreaded “cave sound you have probably been battling with Reverb reduction is actually quite a science given that you re trying to remove elements of a sound that are…well very very similar to the source So you can t just hack out the errant frequencies and be done with it you need to leave the original signal intact NVIDIA kept things nice and simple Other pro tools like iZotope s RX give you an bevvy of settings and controls Broadcast Just two on off and “strength amount of reverb to be removed To test this I used a condenser microphone as those are most prone to picking up reverb In the recording below I start with no effect applied before dialling in about percent and then finally with strength set to maximum Engadget ·NVIDIA Broadcast Room noise removal testsAs you can hear the effect is well effective The acoustics in the room I recorded the samples in aren t terrible but they re definitely not optimal But the difference between the raw recording and then with the reverb removed is stark The effect is most obvious in the first recording with the condenser mic The raw signal is…fine but things are much improved with the echo removal tool set to around half way The recording feels much more present and there s no distracting room echo More isn t always better though Once I dial the effect up to percent reverb might be eliminated but at the expense of the original signal In short play around with the settings to find the best balance for your tastes and recording space You ll notice in the second recording that there s not really all that much reverb to remove This is thanks to the dynamic microphone which does a pretty good job of that itself You can hear a difference once I start adding the effect but it might not be worth the risk of degrading your source audio for such a minor benefit Perhaps more impressive than the echo removal is the second effect on offer Noise reduction While reverb tends to be a constant outside noises are unpredictable Things might be quiet when you sit down to record only for a loud motorbike or barking dog to invade your stream moments later Not with noise removal applied though This effect is impressively adept at removing anything but your voice from your stream Be that a jackhammer a crying baby next door or even a song played loudly on a speaker right by your microphone Honestly listen to the below Notice how you can t hear the song when the effect is applied That s coming from a speaker barely a foot behind the microphone When I recorded it it s fully audible to my ears but almost entirely inaudible on the recording I say almost as those with sharp ears might notice the odd fragment popping through but you really have to listen closely I actually asked NVIDIA about this and was given this response “The AI networks are trained to recognize some patterns and as such there will be gray areas where the AI can have doubts As such we wanted to give our users flexibility to run the effects in a comfortable range or dial things up in case they needed help in extreme situations For example for audio effects we recommend running them at percent depending on how much background noise or room echo there is As mentioned Broadcast largely replaced RTX Voice but NVIDIA decided to patch it with support for NVIDIA GeForce GTX GPUs meaning you can still get the noise reduction tools even if your GPU doesn t support Broadcast Though the company says experiences will vary on older cards As with the reverb removal the strength setting will ultimately impact the quality of the output so trial and error is needed to find the sweet spot You might also want to consider time of day If for example you live near a noisy road you could dial in a second pair of settings for when you have to record around rush hour The noise removal filter is impressive but it s not without limitations For one the “strength slider doesn t seem to fade out sounds like music instead it falls off only once you apply the maximum amount At least in my testing I doubt you re intentionally streaming with music only you want to hear so that s a minor thing to be aware of but if you do need to keep the strength at maximum be aware of that degradation in signal which will get worse the more noise Broadcast is eliminating As a companion to the vocal effects the middle tab in Broadcast is “Speakers We can sum this section in one shot It s the same as Microphone just for incoming audio That s to say you can go ahead and remove room echo or background noise from people you are speaking with If you ve ever been on a Zoom call during these pandemic times and someone s baby starts crying or has a really loud road nearby then you can selfishly spare your ears here Camera toolsConceptually the effects for your camera work in a similar way to the ones for your microphone NVIDIA s AI cores are “looking out for noise or depending your entire background Yup with Broadcast you can achieve a green screen effect without the actual screen You might be thinking “well Zoom Meet TikTok does that and you d be right but those don t do it nearly as well Below is an example of what background removal replacement looks like in BroadcastJames Trew EngadgetYou can definitely see where the effect isn t perfect around my hair but in general it works really well I did notice that it struggled with the headrest on my chair with the image flickering around that area as I moved around but again it s leagues above what you might hope for from a free chat app In total there are five effects for cameras Three for your background Blur removal and replace images or videos work Then there is Auto Frame which crops in and then keeps your face in the center Last but not least is Video noise removal ーthis is apt for recording in low light and your camera starts to go all grainy You can see some examples in the picture below Two were taken using a GoPro and the other pair are from an old DSLR repurposed as a webcam If you have good lighting you probably won t need the noise removal tool But if your camera struggles with anything other than an abundance of photons this filter can help Again as with the audio tools be aware that more is not always better I found with the effect applied at percent you get the tell tale “smoothing that will tell your viewers that you re papering over the cracks James Trew EngadgetThe background tools on the other hand are a little more forgiving The blur tool does a good job at obscuring the items behind you but there s a very unnatural contrast between you in focus and literally anything else in shot This is similar to how iPhone “portrait mode photos often appear The background is blurred but the subject looks unnatural as there s almost no transition between foreground and background This is of course a benefit when you want to remove the background completely With this filter NVIDIA does a surprisingly good job of isolating you and deleting everything else If you want to stream via OBS or similar with a game or video on screen while you play in the corner this is the effect you want and no green screen required James Trew EngadgetAs seen above NVIDIA does a much better job of removing the background than say Zoom or Google Meet does There s almost no bleed around hair or hands meaning your background rarely pokes through and spoils the green screen illusion Background replacement is essentially an extension of this effect with the option of choosing your own image or video to replace whatever happens to be behind you The last of the video effects is Auto Frame which as the name suggests keeps you locked into the center of your shot To do this the video crops in a little bit and it uses the extra space to gently shift the video from left to right or vice versa as you move around The movement isn t jarring it looks pretty smooth and is a good way to make sure you don t accidentally drift off to the side if you are a fidgeter like me and don t keep still You can also combine these effects if you want Auto Frame can be stacked with either noise removal or one of the background effects for example or you could use remove background with noise removal applied Right now you can only stack two though but that s probably a good thing as all three at the same time might be a bit much The camera suite of effects is currently in beta and NVIDIA has been adding new features and improving performance at a rapid pace Version in May integrated Broadcast into popular streaming apps like OBS while the latest version released in September added support for many virtual camera apps and made combining video effects much more viable by reducing their VRAM usage by percent While performance and memory usage is never going to be an issue for those using Broadcast for their chats one PC streamers who are using the app while gaming will be grateful for the additional frames Perhaps one day we can dare to dream about many other features such as multi mic support with different effects live transcribing for closed captions and even smart detection of licensed music so your streams don t flag a DMCA violation	2021-11-02 14:15:26
