海外TECH	DEV Community	Finding strongly connected components (SCC) in directed graphs: Kosaraju-Sharir vs Tarjan’s algorithm in Go	https://dev.to/abaron10/finding-strongly-connected-components-scc-in-directed-graphs-kosaraju-sharir-vs-tarjans-algorithm-in-go-42pa	Finding strongly connected components SCC in directed graphs Kosaraju Sharir vs Tarjan s algorithm in GoGraphs are non linear data structures in which a problem is represented as a network by connecting nodes and edges examples of this can be networks of communication flows of computation paths in a road connections in social networks etc The next image shows graph connections of Facebook for the year Figure Population centers in bright white from the density of intra city friendships This image shows interesting information such as which countries the app has more or less influence you can also see cultural relations between countries Hawaii to the continental US Australia to New Zealand Colombia to Spain you could also observe country outlines like India isolated in the dark void of China and Russia In short Graph algorithms offer the tools required to understand model and establish connection behaviors of systems at a high level of complexity This article will discuss the theory behind the most popular algorithms to find strongly connected components SCC the time complexity of each and finally compare both algorithms using benchmarks on directed graphs Let s start defining what directed graphs are Directed GraphsA directed graph also known as Digraph is a type of graph in which the edges have a defined direction Figure unlike an undirected graph in which the edges are symmetrical relations and do not point in any direction the edges are bidirectional Figure Figure Representation of a directed graph Figure Representation of an undirected graph A graph is connected if there is a path between every pair of vertices in digraphs there are two classifications depending on the nature of the connections weakly connected and strongly connected A digraph is called weakly connected if it is possible to reach any node starting from any other node by traversing edges in some direction not necessarily in the direction they point Figure Illustration of a weakly connected digraph On the other hand a digraph is called strong connected if for each pair of vertices u and v there is a path from u to v and a path from v to u in other words if there is a path in each direction between each pair of vertices of the graph Figure Connection between U V and V U To find this strong connected components DFS Depth first search can be used the two most famous algorithms that use this traversal technique are Kosaraju Sharir algorithmTarjan s algorithm Kosaraju Sharir algorithmIn the year computer scientist S Rao Kosaraju proposed an implementation of the algorithm but did not publish it Independently computer scientist Micha Sharir discovered it and published it in The main idea of the algorithm is based on the fact that the strongly connected components of a graph A are exactly the same as those of the transposed graph of A reversing all the edges of graph A Algorithm steps Create a graphFor the creation of the graph an adjacency list will be used an adjacency list consists in a collection of unordered lists child nodes grouped by a map where each key represents the parent node The code shown below handles an implementation of the graph with a struct having the following fields nodes this field has the purpose of keeping track of all labels associated to vertices in the graph reversed As said before Kosaraju Sharir algorithm makes use of the transposed graph to save unnecessary iterations like traversing the graph to find the transposed simply when adding a new edge to the base graph also add the same edges in reversed direction See section line edges Adjacency list of the graph package kosarajuSharirimport g SCC analysis graph fmt github com abaron Gothon gothonSlice type graph struct nodes int reversed graph edges map int edge type edge struct from int to int func newEdge from int to int edge return amp edge from from to to func NewGraph g Graph reversedGraph amp graph nodes int edges map int edge return amp graph nodes int edges map int edge reversed

newEdge from to g edges from edges g nodes append g nodes from Computing transposed graph at the same time user adds an Edge if g reversed nil g reversed AddEdge to from Section AddEdge method required to populate base and reversed graph Section Graph implementation Topological Sort with DFS traversalTopological sort is a linear ordering of vertices such that for every directed edge u v vertex u comes before v in the ordering Create an empty stack do DFS and after finishing all recursive calls for all adjacent vertices of a node append the visiting node to stack func g graph calculateStackBaseOrder int visited map int struct stack int for node range g nodes if ok visited node ok g dfs node visited amp stack return stack Section Topological sort on base graph Depending on where DFS starts and the order in which nodes are visited the stack will be populated don t forget to visit all the nodes in the graph hence the importance of the slice nodes remember this attribute of the struct has the purpose of keeping track of all added labels in the graph The iteration on g nodes See section line will go one by one comparing against the visited set if there is an unvisited node the code pass it through the DFS implementation func g graph dfs from int visited map int struct stack int visited from struct edges ok g edges from if ok for edge range edges if ok visited edge to ok g dfs edge to visited stack stack append stack from Section DFS implementation to traverse base graph and populate the stack Reverse GraphWhile adding new edges with the method addEdge the reversed graph was also getting populated with the reversed edges that means that at least with this implementation the reversed graph has already been computed Second DFS traversal on reversed graph following topological sort found on step At this step the algorithm already computed the topSort order on the base graph now traverse the reversed graph in that order To do this first define a second DFS traversal function and pop nodes from orderNodes while orderNodes is not empty To pop the slice an handle it like a stack the code is using Gothon s library take the popped node and call the reversed DFS implementation see that a counter and a map called scc are being passed to the method in order to tag the strongly connected components func g graph findSCCComponents orderNodes int map int int visited map int struct scc map int int counter for len orderNodes gt using library to emulate stack popping as Python do node gothonSlice Pop amp orderNodes if ok visited node ok g dfsReversed node visited scc counter counter return scc Section Computing strong connected components popping the order from the stack Similarly as the previous topological sort after calling recursive DFS for all adjacent edges of a node the node label is saved as a key in the map with the respective SCC identifier given by the counter func g graph dfsReversed from int visited map int struct scc map int int counter int visited from struct scc from counter edges ok g reversed edges from if ok for edge range edges if ok visited edge to ok g dfsReversed edge to visited scc counter scc from counter Section DFS implementation to traverse transposed graph and populate the SCC map After computing both traversals on the map scc there can be found keys corresponding to node labels and the values corresponding to the SCC identifier Time complexity Kosaraju s algorithm performs Depth First Search on the directed graph twice Since the implementation is using an adjacency list each vertex is processed with all the neighboring edges as a result of this time complexity is Where V corresponds to the vertices and E the edges within a graph Tarjan s algorithmInvented by Robert Tarjan in the structure of the algorithm is based on the fact that the strongly connected components together form subtrees whose roots are the strongly connected components Algorithm steps Create implementationThe implementation of the graph is similar to the explained previously for Kosaraju s algorithm using and adjacency list the difference lies on the addition of the following fields to the struct stack Keeps track of the nodes visited while forming a subtree of the graph onStack Keeps track of the nodes in the stack avoiding iterating over the slice to check if a node exists or not id Incremental identifier of a node within a formed subtree ids This field use a map whose function is to translate node label to current incremental id within the graph lowLink Tarjan s algorithm maintains a low link number which is initially assigned the same value as the id number when a vertex is visited the first time package tarjanimport g SCC analysis graph fmt github com abaron Gothon gothonSlice type

node both with the same value Append visited nodes to the stack Figure Example of tagging low links and ids for nodes starting DFS on See that on figure the next node to visit from node is but is already in the visited stack if this happens calculate the minimum low link value between the current node and the node in the stack If the value of the node in the visiting stack is smaller a strong connected component has been found Propagate low link value if found SCCAfter calling recursive DFS for all adjacent edges of a node if the current visiting node created a strong connected component pop nodes off stack until reaching the node that started the recursive DFS While doing this update the new low link value of each popped node The advantage of this is the propagation of low link values throw graph cycles func g graph dfs from int graph map int edge visited map int struct visited from struct g id g ids from g id g lowLink from g id g onStack from struct g stack append g stack

graph Algorithm s evaluationTo test both algorithm s Digraph on figure will be used See that there is a path in each direction between pairs of vertices on each connected component Figure Example of

on figure Figure Benchmark of both algorithms On figure on the right side of the function name for SCC with Tarjan s Algorithm the SCC calculation was executed times with an average of ns op nanoseconds per operation while SCC with Kosaraju s Algorithm was executed times with an average of ns op On this test Tarjan s algorithm is faster finding SCCs with an advantage of ns op over kosaraju s algorithm This can be explained understanding the basic approach of the two algorithms Kosaraju s algorithm performs DFS twice unlike Tarjan s algorithm where the graph is only traversed through DFS once Both algorithms have linear time complexity but as evidenced by the benchmark Tarjan s algorithm has a more efficient handling of operations per unit of time and a better control of constant factors saving additional DFS navigations Memory allocation statisticsIn terms of allocated space the benchmark test is using MB in total for both approaches but notice on figure that around MB of the memory goes to Kosaraju s algorithm the other MB was allocated by Tarjan s Figure PPROF on both algorithms to check allocated memory It can be affirmed looking at figure that Kosaraju s algorithm uses more memory than Tarjan s algorithm partly due to a greater number of recursive calls when traversing the base graph allocating memory on the stack and also having the pointer in memory of the transposed graph at running time Figure PPROF on both algorithms to check allocated memory To avoid keeping the pointer of the transposed graph in memory a valid option can be reversing the original graph at running time but once the calculations with the transposed graph are finished the graph must be reversed again in order to achieve the original configuration With this approach the graph must be traversed at least twice doubling the constant execution times ConclusionsBoth algorithms perform similarly in general execution time O V however Tarjan s approach is more efficient with constant factors of time and memory at execution In software everything is a tradeoff but due to performance challenges in highly complex distributed systems any gain in time even in units of nano seconds is a significant gain Under this premise Tarjan s algorithm is a much more attractive option Tarjan s algorithm has more development complexity than Kosaraju s however both algorithms serve as tools to better understand graph theory and its applicability to the world of technology Code implementation ReferencesBang Jensen amp Gutin p in the edition p in the nd edition text A weakly

海外TECH	DEV Community	How to effectively store and ANALYSE logs in AWS CLOUD	https://dev.to/aws-builders/how-to-effectively-store-and-analyse-logs-in-aws-cloud-1k0d	How to effectively store and ANALYSE logs in AWS CLOUDServices and applications typically create logs that contain significant amounts of information This information is logged and stored on persistent storage allowing it to be reviewed and analyzed at any time By monitoring the data within your logs you can quickly identify potential issues you want to be made aware of as soon as they occur Resolving an incident as quickly as possible is paramount for developing real life solutions Having more data about how your environment is running far outweighs the disadvantage of needing more information especially when it matters to your business in the case of incidents and security breaches Some logs can be monitored in real time allowing automatic responses to be carried out depending on the data contents of the log Logs often contain vast amounts of metadata including date stamps and source information such as IP addresses or usernames This blog aims to help you understand how to store and analyze logs in AWS and some recommended practices Storing and analyzing logs in AWS can be done using various services and tools depending on your requirements and use case Here are some services you can consider A AWS CloudWatchAWS CloudWatch provides valuable insights into the health and performance of your applications and resources which can help you optimize their performance increase availability and improve the overall customer experience  Various components of Amazon CloudWatch include Dashboards  You can quickly and easily design different dashboards to represent the data by building your views For example you can view all performance metrics and alarms from resources relating to a specific customer Once you have built your Dashboards you can easily share them with other users even those who may not have access to your AWS account   Note  The resources within your customised dashboard can be from multiple different regions   Metrics You can monitor a specific element of an application or resource over time for example the number of DiskReadson in an EC instance   Anomaly detection allows CloudWatch to implement machine learning algorithms against your metric data to help detect any activity generally expected outside the normal baseline parameters  Note Different services will offer different metrics Amazon CloudWatch Alarms  You can implement automatic actions based on specific thresholds that you can configure relating to each metric For example you could set an alarm to activate an auto scaling operation if your CPU utilization of an EC instance peaked at for more than minutes There are three different states for any alarm associated with a metric OK The metric is within the defined configured threshold ALARM The metric has exceeded the thresholds set INSUFFICIENT DATA There is insufficient data for the metric to determine the alarm state Image credits CloudWatch EventBridge You connect applications to various targets allowing you to implement real time monitoring and respond to events in your application   The significant benefit of using CloudWatch EventBridge is that it allows you to implement the event driven architecture in a real time decoupled environment   Various elements of this feature include Rules A rule acts as a filter for incoming streams of event traffic and then routes these events to the appropriate target defined within the rule The target must be in the same region  Targets Targets are where the Rules direct events such as AWS Lambda SQS Kinesis or SNS All events received are in JSON format  Event Buses It receives the event from your applications and your rules are associated with a specific event bus   CloudWatch Logs You have a centralized location to store your logs from different AWS services that provide logs as an output such as CloudTrail EC VPC Flow logs etc in addition to your own applications An added advantage of CloudWatch logs comes with the installation of the Unified CloudWatch Agent which can collect logs and additional metric data from EC instances as well as from on premise services running either a Linux or Windows operating system This metric data is in addition to the default EC metrics that CloudWatch automatically configures for you  Various types of insights within CloudWatch include Log Insights Container Insights and Lambda Insights B AWS Cloud Trail AWS CloudTrail records and tracks all AWS API requests It captures an API request made by a user as an event and logs it to a file it stores on S CloudTrail captures additional identifying information for every event including the requester s identity the initiation timestamp and the source IP address You can use the data captured by CloudTrail to help you enhance your AWS environment in several ways Security analysis tool  Help resolve and manage day to day operational issues and problems  C AWS COnfig AWS Config records and captures resource changes within your environment allowing you to perform several actions against the data that help optimize resource management in the cloud AWS Config can track changes made to a resource and store the information including metadata in a Configuration Item CI file This file can also serve as a resource inventory It can provide information on who made the change and when through AWS CloudTrail integration AWS CloudTrail is used with AWS Config to help you identify who made the change and when and with which API Note AWS Config is region specific Image credits D AWS Cloud front logs Enabling CloudFront access logs allows you to track each user s request for accessing your website and distribution These logs contain information about the requests made to your CloudFront distributions such as the request s date and time the requester s IP address the URL path and the response s status code Amazon S stores these logs similar to S access logs providing a durable and persistent storage solution Although enabling logging is free S will charge you for the storage used E AWS VPC Flow logsVPC Flow Logs allow you to capture IP traffic information between the network interfaces of resources within your VPC This data aids in resolving network communication incidents and monitoring security by detecting prohibited traffic destinations Note VPC Flow Logs do not store data in S but transmit data to CloudWatch logs Before creating VPC Flow Logs you should know some limitations that may affect their implementation or configuration  If you have a VPC peered connection you can only view flow logs of peered VPCs within the same account   You cannot modify its configuration once you create a VPC Flow Log Instead you need to delete it and create a new one to make changes You need an IAM role with the appropriate permissions to send your flow log data to a CloudWatch log group You select this role during the setup configuration of VPC Flow Logs Recommended practices for storing and analyzing logs in AWS By following these best practices you can effectively store and analyze logs in AWS and improve the reliability and performance of your applications Define a consistent logging format such as JSON or Apache Log Format Use log rotation to prevent from taking up too much storage space You can use AWS Elastic Beanstalk helps to automate log rotation  Set up alerts to notify you of any critical issues in your logs to quickly resolve any issues Amazon CloudWatch helps to set up alerts based on predefined thresholds or custom metrics Use encryption to protect your log data in transit and at rest Amazon S server side encryption or Amazon CloudFront field level encryption helps protect your data You should regularly review and analyze your logs to help identify potential issues AWS services like Amazon Athena Amazon Elasticsearch Service and AWS Glue help you gain insights Use a log aggregation service to centralize your logs across many AWS services AWS CloudTrail or Amazon CloudWatch Logs helps to centralize your logs  Implement a data retention policy that specifies how long you need to keep your log data To help avoid unnecessary storage costs and ensure compliance with regulatory requirements  By monitoring the data within your logs you can quickly identify potential issues you want to be made aware of as soon as they occur In addition by combining this monitoring of logs with thresholds and alerts you can receive automatic notifications of potential issues threats and incidents before they become production issues By logging what s happening within your applications network and other cloud infrastructure you can build a performance baseline and establish what s routine and what isn t	2023-03-22 15:12:53

海外TECH	Engadget	The best passive bookshelf speakers for most people	https://www.engadget.com/the-best-passive-bookshelf-speakers-under-600-dollars-for-most-people-140057354.html?src=rss	The best passive bookshelf speakers for most peopleVinyl has been on a resurgence for some time and the pandemic somehow only accelerated that It s got many out there looking to upgrade from a cheap Crosley turntable and build out their first HiFi system Of course there are multiple pieces that go into building a decent stereo but perhaps the most important is the speakers If your speakers don t sound good it basically doesn t matter what you connect them to Active vs Passive SpeakersThis is understandably the part of their setup that people likely spend the most time researching And you have to make a number of choices One of the biggest is active or passive Both have their advantages but for the sake of this guide we re going to focus on passive speakers which require a separate amplifier Active speakers have a built in amplifier Usually the two things are specifically designed to work together which means you re getting a more faithful version of the manufacturer s aural vision And since you don t need an external amplifier active speakers also take up less room While active speakers are more expensive than passive the fact that you need to buy an amp to power passive speakers means the savings aren t as great as they might initially seem The primary benefit of passive is greater flexibility You can t go out and buy a new high end amplifier and connect your active speakers to it you re stuck with what s built in Also since active speakers require power you ll have to make sure they re near an outlet Terrence O Brien EngadgetWe re also putting a cap on our spending for this guide a somewhat arbitrary Anything over that and you re starting to get into budget audiophile territory It also basically limits us to bookshelf speakers between five and six inches While you can certainly get floorstanding speakers for that much the quality of the drivers will likely be better on bookshelf speakers at the same price point A note about testingObviously I could not test every set of five to six inch bookshelf speakers under but I ve tried enough and done enough research to feel confident in my recommendations I m sure there are other good speakers out there but I don t think anyone is going to regret buying the sets here Additionally speaker preference is largely subjective But I did my best to be as objective as possible All of the speakers were connected to a Pyle PSS switcher with the same wire for quick side by side comparisons After I d tested them all myself I enlisted multiple people to listen blindly and then rank them based on their preference to see if their opinions lined up with my own Testing included playing new and vintage vinyl as well as streaming songs from Spotify Also worth noting I am not an audiophile This is not a guide for audiophiles I want my music to sound good but I m not about to drop the price of a used sedan on my stereo My setup includes an Audio Technica Audio Technica AT LP and a Chromecast Audio running through a Technics SA EX This is not fancy stuff but it is certainly an upgrade from a Crosley Suitcase turntable or even a higher end Sonos sound system The best for most people Audioengine HDPHonestly a lot of the speakers I tested sounded eerily similar to each other But not the Audioengines They had a much brighter sound and a lot more clarity than all the others with the exception of a significantly more expensive KEF pair The particular pair I tried also came in a gorgeous “walnut enclosure that helped them stand out in a sea of utilitarian black The HDPs deliver especially strong mids that shine when it comes to vocals and guitars But they sound quite balanced across the entire spectrum Towering compositions like Nine Inch Nails “The Day the Whole World Went Away sprung to life and revealed nuances that frankly I ve never noticed before even on headphones And Promises the recent album from Floating Points Pharoah Sanders and the London Symphony Orchestra was so enveloping it made me want to throw my current floorstanding speakers in the trash While no bookshelf speakers on their own are going to be able to deliver the sort of room shaking thump that floorstanding speakers or a subwoofer can deliver the HDP performed admirably with bass heavy songs They didn t have the most low end of my test units but drums and bass were still punchy and clear For those who want the best sound KEF QIf your number one concern is sound quality regardless of anything else check out the Qs These are the entry level option from noted audiophile brand KEF and the only speakers that beat out the Audioengines in any of my blind taste tests They didn t come out on top every time and some people had trouble deciding between the two but ultimately I think the KEF s have the slight edge in pure sound quality They had a bit more volume at the extreme lower and higher ends of the spectrum It added a certain sparkle to tracks like the Beach Boys “Wouldn t it Be Nice while Run the Jewels “JU T hit a little bit harder than on the HDPs The difference can be subtle depending on what you re listening to but it s undeniable in side by side testing The audio profile of the KEF is similar to that of the Audioengines They re both much brighter and with a lot more treble and midrange than all the other speakers in this roundup If you re into listening to classical or jazz on high quality vinyl these are going to deliver exactly the sort of frequency response you re looking for What stops the Q from topping this list is the list price At they re essentially tied for the most expensive speakers I tested The Polk Rs were but didn t make the final cut While the Qs sounded slightly better than the HDPs to my ears they weren t necessarily better At the time of this writing however the Qs were on sale for making them a compelling option to the Audioengines For the bargain hunter JBL AThe JBLs were pretty consistently in the middle of the pack when it came to listener preference They re not as bright as the KEFs and the Audioengines but not quite as muddy at the lowend as the Polk Ss If you re just looking for a decent set of speakers and don t sweat over spec sheets or if you re primarily listening to streaming music and only putting on vinyl occasionally these are a great option if you can find them on sale For those that need more bass ELAC Debut DBOk so these speakers break our rules a bit but if you opt for the slightly larger inch DBs instead of the DBs you get a lot more thump at the bottom end The Debuts can t quite match the Audioengine or KEFs when it comes to clarity but you ll feel every hit a lot more Backxwash s new album I Lie Here Buried with my Rings and my Dresses raged harder on the ELACs than it did on the Polks JBLs or even the KEFs And they only cost which isn t bad at all If you re primarily listening to electronic music and modern hip hop you might consider the Debut DBs For those who want to ignore my advice If you can t find the JBL As on sale and really want to save as much money as possible you could snag the Polk Ss The Ss don t sound bad but the JBLs are definitely superior They don t have as deep of a soundstage as the other speakers I tested and the lowend can be a little undefined These are probably better suited as part of a home entertainment system than a stereo At a list price of they might seem like a bargain but I d save your pennies for a bit longer and spring for something better The Polk Rs are decent sounding speakers Perhaps slightly better than the JBLs though with a sound profile closer to the Polk s own S The problem is they re tying them for the most expensive I tested At half the price these might be a solid option but the KEFs and Audioengines were ranked higher than the Rs by every tester I have no doubt that these are very good speakers They re currently Wirecutter s top choice But I could not test them and therefore cannot vouch for them This article

海外TECH	Engadget	Nothing’s $149 Ear 2 wireless buds have improved connectivity and more customization	https://www.engadget.com/nothing-ear-2-wireless-buds-price-release-date-impressions-153040749.html?src=rss	Nothing s Ear wireless buds have improved connectivity and more customizationNothing s revealed its second generation Ear wireless buds The eye catching design sticks around and the company has tried to address some of the issues that bedeviled the original with some much needed improvements to connectivity and setup Fortunately the price of the Nothing Ear is the same as the Ear which undercut a lot of the established true wireless competition Nothing hasn t redesigned its buds and case they look very similar side by side but it s made a handful of incremental changes Most of them focus on the case which is smaller and slimmer The outer part of the case is still transparent but part of the white structure is now exposed There s no textured surface just a soft touch panel Nothing claims the see through plastic is harder to scratch and damage than the original Ear In my pockets and bag getting shuffled around with keys or other objects has already left a noticeable scratch on the case I also worry that this exposed panel could get muckier easier the curse of all white gadgets Photo by Mat Smith EngadgetTackling one the bigger complaints I had with the Ear Nothing moved the microphones and antenna inside the buds to improve connectivity and stability something it also did with the cheaper Ear Stick The company s first wireless buds were often finickity when pairing The company has also changed the antenna structure for better reliability and the initial pairing process seems to be less fussy and smoother than its predecessor It s also finally added dual connectivity making it easier to switch between your phone and laptop Microphone placements have also been repositioned to reduce wind noise on calls but I didn t notice major improvements over the Ear Nothing said its Clear Voice tech was tuned to just shy of million sounds on the Ear in order to filter them out while that was closer to million on its newest buds However I made several test calls and I was still difficult to hear when it was windy Nothing says it improved sound detail with polyurethane components for clearer low frequencies it s been a while since a company has sold polyurethane as a feature and graphene for brighter highs There s also a dual chamber design for a wider soundstage The Ear will also be compatible with Hi res audio at launch although they weren t at time of writing and are compatible with the LHDC codec which all means they should work with premium audio standards where you can find them But does it sound all that different Swapping between the Ear and Ear the newest version does offer clearer sound in the trebles and the bass has more oomph than before But compared to wireless buds that are often hundred dollars more expensive like the AirPods Pro or Sony s latest flagship buds they don t quite stand up coming off a little flat Nothing s latest buds offer three levels of active noise cancellation ANC low mid and high The Ear also offer a personalized ANC profile calibrated to your own hearing The test is a lengthy five minutes roughly with a test dedicated to each bud Your mileage and ears will different but I didn t note any marked improvements after calibration The ANC isn t perfect At the highest levels of active noise cancellation still seemed to struggle with the reverberations on trains and the subway leading to a jarring noise echo in my left bud while using ANC despite recalibrating the buds several times in a bid to fix it It s fortunately happening much less often following a firmware update over the weekend There s also an adaptive ANC mode that will flit between levels depending on the noise around you hopefully reducing the toll on battery life Nothing says there are battery improvements across both the buds roughly an hour more to over six hours and the case which can juice the buds for up to hours of listening with ANC off two hours longer than the Ear You should get hours of audio from a minute charge too There s still wireless charging too if you want it Setting up and switching between ANC modes is done through the updated Nothing X app but the Ear predictably work best with Nothing s Phone with drop down shortcuts and easier access to the fine grain controls There s also a custom sound profile calibration to hone in on frequencies you might not hear thanks aging The equalizer again inside the companion app offers more options You switch between treble or bass centric modes a balanced mode and one dedicated to voice My custom sound profile also came with the ability to augment my weaker audio frequencies I had trouble hearing with a richer profile alongside the standard recommended mode You can also tweak the intensity with a slider Photo by Mat Smith EngadgetNothing may have added many minor features and improvements but the Ear isn t shaking up the status quo like its predecessor Given the eye catching hardware of the Ear I wasn t expecting a major redesign they don t need it and the company has addressed my biggest problems with the first headphones It s hard to complain about the range of improvements including upgraded water and sweat resistance rating the buds are IP rated while the charging case is IP The Ear will launch in white on March th on Nothing s own retail site as well as on Amazon and Kith Unfortunately if you were looking to match your black Phone there s no plan for a black option This article originally appeared on Engadget

GCP	Cloud Blog	Proven Here First: ManTech Leads the Way to Google Workspace	https://cloud.google.com/blog/topics/public-sector/proven-here-first-mantech-leads-way-google-workspace/	Proven Here First ManTech Leads the Way to Google WorkspaceManTech a high tech high end engineering and cyber provider to the federal government is making the move to Google Workspace The year old global tech company with the history and expertise in bringing Digital to the Missionwith the best solutions and mission focused technology to the federal community is partnering with Google Public Sector to move its ManTech personnel to Google Workspace This initiative empowers ManTech to bring best in class collaborative cloud based software to their workforce and to every branch of the federal government in supporting critical mission needs  To learn more about ManTech s decision and process behind Google Workspace Troy Bertram Managing Director of Google Public Sector partner sales sat down with ManTech s CIO CTO Mike Uster and ManTech s Business Sector General Managers David Hathaway Defense Adam Rudo Intelligence and Stephen Deitz Federal Civilian Bertram Thanks for taking the time to speak with me today Mike David Adam and Stephen Can you tell us a bit more about ManTech what s your company s mission and how does your organization uniquely support the government services marketplace Uster As a trusted partner of the federal government we specialize in sophisticated technology solutions ranging from Cognitive Cyber to Analytics amp AI high end digital engineering Data at the Edge and Enterprise Cloud all very important to safeguarding national security and advancing the government s core mission of achieving IT modernization   Deitz Our commitment to great talent and innovative solutions is key to ManTech s strategic objective of solving government s toughest challenges effectively and cost efficiently Bertram What motivated ManTech to bring Google Workspace into its IT portfolio  Hathaway Innovation is part of our DNA In fact ManTech will be the first federal systems integrator moving into Google Workspace The timing of our adoption aligns to the Department of the Army and other government customers moving to Google Workspace End Result  Addressing our customers mission needs in ways that only ManTech can   Deitz We view Google Workspace as an important addition to our initial work with Google Cloud which delivers hyperscale analytics high throughput and air tight security for agencies charged with safeguarding national and homeland security as well as meeting the technology needs of Federal Civilian agencies that serve our citizenry Bertram What were the risks and rewards you considered with this migration Uster Reward can be summarized in three words simplicity flexibility and interoperability There s also a wave of next generation workers who grew up using Google products and services like Gmail Docs and Sheets The tools are simple and intuitive For ManTech users and government alike there s really minimal training required We believe using these Google tools will help us and the federal government attract and retain talent while reaping cost savings  Hathaway The U S government spans some agencies and four million employees Over time agencies have evolved from the era of mainframe hardware or “big iron to PCs laptops the Internet email smartphones and other advances but at different paces approaches and time frames Google Workspace provides a rich variety of solutions that uniformly advance IT and communications for each agency and help ensure interoperability between diverse agencies that may be tasked with integral goals and agendas in a secure environment  Bertram How did security factor into your decision making for using Google Workspace Uster  We knew any solution we adopted needed to be FedRAMP High Now that Google Workspace is FedRAMP High and has earned Department of Defense s Impact Level IL authorization the decision to switch was easy With Google Workspace being cloud native this also ensures that our users and data remain secure no matter where our users are Bertram Can you tell us more about how you made the move to Google Workspace Uster ManTech s philosophy and innovation approach when it comes to introducing new technologies to our customers is “proven here first We offer innovation and capabilities for our customers national and homeland security missions which we have built into our enterprise have tested them and gained significant insight into optimizing performance and security   We started small with less than a hundred Google Workspace licenses which we set up in a second ManTech network We ran this pilot for about months to make sure we worked out the kinks and could transition smoothly before implementing more broadly or recommending Google Workspace to our customers Our “tested here first approach gives us firsthand knowledge of the digital solutions we bring to our customers ensuring we bring the best options to their environments  Bertram We know building cultures of innovation within the ManTech workforce and government more broadly is an important initiative for you How do you envision Google Workspace will help you achieve this Deitz Innovative culture is a signature characteristic of both companies In ManTech s case it dates all the way back to the day we opened our doors for business and has grown even stronger and broader over the years If you look at missions around the world ManTech is involved we support U S government customers in many countries The same applies to Google and its leadership in technology advancement everywhere We have strengths that others can t match Uster Google Workspace s cloud native flexible and intuitive tools create frictionless environments for users And with no friction people are able to focus more on innovating rather than figuring out software  Bertram As you mentioned earlier the U S Army recently deployed Google Workspace procuring licenses for up to personnel  How did the U S Army s deployment influence your decision Hathaway As a partner to government and in my case the Department of Defense ManTech s goal is to be where our customers are land sea air space cyber space and everywhere in between As a first mover in the government contracting space like the U S Army was in the government industry we are proud to share that distinction With both of us now being Google Workspace users we are looking at how we can work more collaboratively with the U S Army in a secure environment Bringing our environments together gives us a geometric accelerator to propel collaboration  Bertram How will Google Workspace help support your business growth and engagement within the federal community Rudo  Our partnership with Google is an important part of ManTech s hybrid environment approach We aim to be adept in many productivity tool environments and to guarantee their reliability and security by first testing it ourselves  Hathaway ManTech s work in Zero Trust is one example Our customers trust our work in this area because it s been battle tested here at ManTech The same measure applies to Google Workspace Bertram What advice do you have for anyone leading their own transformation initiatives And specifically what advice do you have for gaining buy in and successful adoption of Google Workspace Uster Be bold and start small Never settle always go for the best whatever it takes ManTech and Google have proved themselves adept at succeeding in areas that others deem “Mission Impossible That s what makes us special to our customers That s what has set ManTech apart from the industry norm since our founding in  Google Workspace is a proven tool within the commercial market and the public sector Now that it s FedRAMP High for the federal space it s a viable commodity for the federal government and defense contractors  So buy a small set of licenses and try it out yourself Special thanks to ManTech General Managers  David Hathaway Defense Sector Adam Rudo Intelligence Sector Stephen Deitz Federal Civilian Sector	2023-03-22
