![]() Production websites will serve as your example and guide to each andĮvery one of the strategies in this guide. Strategies on production websites like, , the official While preparing this course, I’ve implemented each of my performance These strategies have been tested and proven on my clients' sites and others. Used more than 20 different SaaS providers, performance-oriented Rubygems, backend service providers and more and found the perfect technical stack to make the entire performance optimization process simple (even if you’re a new developer or someone with a deep technical background).These strategies have solved 80% of performance problems in most applications. Identified the 4 strategies that account for the most performance impact.Implemented 34 strategies that have been tested by more than 1 million unique visitors.I’ve created an exhaustive checklist for speeding up Rails applications: WATCH ME OPTIMIZE PRODUCTION RAILS APPS AND APPLY THE LESSONS BACK TO YOUR OWN SITE. Wouldn't it be amazing if you could look over the shoulder of an experienced, full-stack Rails developer and watch as they diagnose and solve the performance problems of one of the most popular Rails applications in the world? My guide for optimizing Rails applications covers the entire stack. Worse, no full-stack developer who writes code for a living can keep on top of all of these developments at once. Performance optimization on a full-stack web application is like looking for a black cat in a coal cellar - any one of a thousand things could be the bottleneck for your application. Server Do you know how your memory allocator may be affecting your performance? Delivering an HTML response to the browserĪctually involves hundreds of technologies and levels of the stack.Ĭonstructing a fast website is a bit like constructing a house of cards -Ī problem anywhere in the stack can cause it all to collapse.Īny of these levels or stacks can go wrong, causing a slowdown in your application: I'll show you how to audit and fix your server spending. Most Rails applications should be spending thousands of dollars per month less than they are now. I can show you how to make your site faster and grow your business by at least that much and more.ĭid you know that most Rails applications I've seen in my consulting gigs have been spending more than 2x per month what they needed to? ![]() If your business is doing $1 million per year, reducing browser load times by 1 second will increase revenue by $50,000 to $100,000 per year. I've consulted for dozens of clients on making their Rails apps faster, and taught hundreds at workshops.īut I've never met a Rails application I couldn't make faster.ĭid you know that an extra second of load time reduces revenue by 5 to 10%? This result has been experimentally verified at dozens of companies large and small. Others were the passion projects of developers looking to start a side business. Many were for well-funded startups, from Ivy-League incubators like YCombinator or 500Startups. Over the past 10 years, I've seen dozens of different Rails codebases. I also maintain Puma - my code is probably already running on your servers, today.

Take a look at the following sections for the most reliable solutions that helped many users overcome this issue. No matter which “version” of the problem you’re experiencing, there are working solutions that you can apply with ease, and you don’t need to be a computer expert to do it. It could be their internet connection’s speed sharply dropping, their CPU taking way too much time to process the downloaded files, insufficient disk space, or even an unknown bug or an error.Ī similar problem is when the app is unable to update itself, making it practically unusable, along with all the games you have on it. 5 Ways to Fix “ Update Agent went to sleep.When someone reports their update being “stuck,” it can mean a lot of things.They are always available to provide help and guidance to their customers. In such cases, we highly recommend that you reach out to Blizzard’s official support team for assistance. It’s worth noting that computer issues can sometimes be highly individualized, meaning that the aforementioned solutions might not necessarily work for everyone. Here is a detailed, step-by-step guide from the Blizzard support team on how to implement the Selective Startup method easily.Īfter going through this article, you should have a good understanding of the possible reasons why the update freezes and most importantly, how to resolve it. The selective startup is a method that allows your PC to boot and run only specific programs or none at all immediately after, thereby reducing the likelihood of interference with the app’s proper functioning. Often, users are unaware that third-party applications and programs running in the background can interfere with the Battlenet app’s ability to update. This approach was also mentioned in the same Reddit thread as Solution 1 and has proven to be effective for many users. The Blizzard support team suggests this method as another recommended solution, as it has proven to be a common cause of the issue. Rebooting your PC is not mandatory, but we recommend it before moving on to ensure that no processes are active and running in the background that may conflict with the upcoming installation setup. Search for any other processes related to the app and close them.ģ. Open the Task Manager and navigate to the Processes tab, then search for the Blizzard Update Agent.Ģ. If your app is already running, close it as you would any other app or use the Windows Task Manager if it is frozen or stuck.ġ. ![]() This easy fix was recommended by an official representative of the Blizzard customer support team in a Reddit thread. This is especially helpful if you are using public Wi-Fi, which often has a limited or barely-functional download speed. In this case, if calling your ISP ( Internet Service Provider) and resolving the issue that way is not an option, we recommend manually restarting your router or connecting to a different network. If you notice that your internet connection’s speed is not performing as it should, particularly for downloads, it is likely the root of the problem. To check this and quickly eliminate it as a possible reason, use Speedtest by Ookla, a website that measures the performance of your connection in just a few seconds in a user-friendly way. ![]() If the problem with your updates is not technical or related to the app itself, it may be due to an underperforming internet connection. Here are some of the most reliable solutions that have helped many users overcome this issue: 1. Regardless of the “version” of the problem you are experiencing, there are working solutions that you can apply without needing to be a computer expert.

![]() Just because (a car) doesn’t strike you doesn’t mean it’s not special,” he warned. ![]() Like every guy I talked to, he is less interested in hierarchy and more interested in variety. His friend, Sam Collier of Taylor, agreed. “When you come to something like this, no matter how bad what you got is, you’re gonna see something a little badder.” In Stanley’s eyes, no one customizer or restorer cruising Downriver could ever win majority approval. “Those are like glass bubble cars,” he said. “You’re putting me in a rough spot we’re all friends!” he said.Īnd furthermore, this is not a Barrett-Jackson auction, where a 1970 Plymouth Hemi Barracuda recently went for over $2 million. “Well then,” I asked, “what’s the best car among this group?” Some of these guys don’t speak to each other throughout the year, “but they make it a point … to meet at the cruise.” “It’s really hard to do,” said Dan Stanley of Allen Park.Įvery Cruisin’ Downriver, Stanley organizes a group of “old friends” ? about 20 cars and their drivers ? to meet in Lincoln Park and watch the Fort Street action. I imagined it would go something like this: most model Chevelles and Mustangs, custom fiberglass hot rods, a 1969 Road Runner 440. I began the night with the idea that I would poll people and try to establish a classic car hierarchy. “It was something that a great-uncle of mine had,” Wolff said with a shrug. In front of Wolff was a car on fire, and behind him was Dearborn Heights resident John Farley and his 1940 Chevy, a car whose license plate retracts when the key is pulled from the ignition, is equipped with citizens band radio and global positioning system, and is so perfectly restored inside and out that it took first at Autorama last year in the custom coupes from 1935-48 division and recently was appraised at $40,000.Īnd when Wolff fell asleep Friday, he did so counting Delta 88s. But there it was, firing away, in front of two patrolmen on motocycles looking the other way.Īnd at that moment, I turned to Brian Wolff of Southgate and asked him, “What’s the best car you’ve seen tonight?” and without skipping a beat, he said, “A Delta 88.” I also didn’t expect that when Trosen said he had a magazine article about it, he would pull out a dusty, 1986 issue of Popular Hot Rodding with his car on the cover.Īnd yet, then again, when I arrived Friday night, I didn’t think I’d see a car (“Sh’ Boom”) with flames shooting out of its tailpipes. Ford did, and ran its lightweight ? comparatively ? midsize at Talladega, but Mercury stopped at 25. In order to run a “stock” car on the circuit, a manufacturer had to produce 100 models. The Cyclone was Mercury’s reluctant lock step onto the Ford Fairlane assembly line when Ford was considering its model for NASCAR. I also didn’t expect to get a history lesson from a guy who looks like he drinks Pennzoil boilermakers and whittles pig iron in his spare time, but there was Jim Trosen of South Lyon showing off his 1966 Mercury Cyclone with the 427- cubic-inch block. “When this car was 10 years old,” Law recalled, “my friends said to me, ‘What, are you gonna keep this car forever?'” He nearly gets choked up when he considers that he could have raced it on the eve of its closing in 1997. ![]() ![]() Law raced his Ford at the Detroit Dragway the very first night owner Gil Kohn “legally” opened the track in 1959. He began customizing it the same year he bought it, welding the seams, removing the door handles ? they now open by remote control ? and tinting the back windows with light blue film manufactured in France at the time and shipped over. I didn’t think I’d see a 1957 Ford being shown off by its original owner.īut there was Dick Law of Gibraltar, standing next to the car he’s owned for 49 years. Somewhere there’s a shredded fan belt he’ll piece back together with some bubble gum and human hair. ![]() – they apparently regarded the proportionality analysis as an ad-hoc balance between the rights of the appellant and the rights of the others in attendance, rather than a structured process of justification that revolves around evaluating the legitimacy, relevance and strength of the state interests in the restriction.Īlso, as Justice Arnold notes at para, we supplied three alternative approaches to interpreting the offense of offensive behaviour, all of which we said were consistent with the Bill of Rights, and none of which were adopted by the District and High Court judges.įinally (and I’m taking this from the notes I wrote during the break in order to respond to William Young P’s question), we emphasised that the fundamental failure of the judges was in adopting the wrong approach to the question of justifying restrictions on free speech. – they did not consider the relevance of the offence of flag-burning under the Flags, Emblems, and Names Protection Act 1981 – they did not properly apply the Brooker test, which significantly lifted the bar in cases of protest nor did they create and apply an analogously high bar for offensive behaviour – they appeared to treat the symbolic nature of the act of flag-burning as an aggravating rather that mitigating factor – they did not consider whether the appellant’s conviction was “demonstrably justified” in a free and democratic society – they did not identify any legitimate purposes for the restriction on the appellant’s right to burn the NZ flag, the starting point for any proportionality analysis – they did not properly assess the significance of freedom of expression in the circumstances of this case ![]() – they did not acknowledge that limitations on BORA rights should be construed narrowly, convincingly established, and strictly applied in favour of the rights at issue – they did not acknowledge that the right to offend, shock or disturb is an indispensable aspect of freedom of expression, and particularly political expression – they did not adopt a rights-centred approach The courts below failed to properly conduct an analysis of the impact of ss14 and 5 of the BORA in that: Second, here our our written submissions on the errors of law in the courts below: It characterised this as a question of law. First, the Court of Appeal itself gave leave on the of whether the conviction was consistent with the Bill of Rights Act. But such a challenge, at least in simple terms, is off-limits in this Court in a second appeal… This rather makes me think that the fundamental challenge to the conviction turns on the factual accuracy of the findings made in the District Court and the High Court. His answers were variations on the theme that the outcome was simply wrong. In the course of argument, I pressed Mr Price for the appellant to identify an error of law made in the Courts below. You’ll see that at para, William Young P says: But I do want to make one point, despite knowing that it’s a bit naff arguing the toss with a judge after a judgment. I won’t go into a detailed analysis of the judgments. The Supreme Court may yet grant leave for an appeal. Still, perhaps the final chapter has not yet been written. (I think her dissent is very convincing, but I would say that: Tony Shaw and I represented Valerie.) Justice Arnold and the President of the Court of Appeal, William Young, voted to uphold the conviction. (For some reason, this wasn’t regarded as a “decision of public interest”, but it’s posted here). Valerie Morse has lost her appeal to the Court of Appeal over her conviction for flag-burning at the Anzac Day Dawn Service. ![]() Budget leak: Nats’ behaviour “entirely appropriate”?.When free speech creates disorder or hate.NZME admits it misled listeners by buying into Trump’s ridiculous election fraud claims – but BSA somehow finds broadcasting standards not breached. |
