You need to be able to work properly with version control systems, continuous integration tools, virtual machine management services (like Vagrant) and, obviously, your integrated development environment (IDE). Second, but no less important, is working knowledge of the supplemental tools you use everyday in your workflow. If you are a LAMP developer, you undoubtedly need to be an expert in PHP and MySQL, know modern frameworks, and have some decent skills in Linux administration.
#Phpstorm 10 very slow software#
This is one of the reasons I've gotten so excited about embedded and low-level programming: You can ditch the OS, and make programs that respond in a way that feels instantaneous.What does it mean to be a good software developer?įirst, it requires deep knowledge of the particular tech stack you’re working in. In order to fix this, we may need a new generation of operating systems and software, built from scratch, with a focus on performance (ie responsiveness). Most web apps use layers of frameworks, cookies, trackers etc that make them take up much more space, and make them less responsive. A mirror that may be easier to GROK is the web: Web apps can be small and responsive by using targeted DOM-manipulation. More broadly, it's unoptimized software, and various pieces of software competing for resources and scheduling. The answer to your question depends: For office settings like I described, it may be due to forced network requests, and surveillance/compliance software. It takes me (at work) 5 minutes to log in 2 minutes to open a MS office app or email 5-10s to save a document 20s to insert a row in Excel. In work environments, it can be even worse. See Wirth' Law: : "Wirth's law is an adage on computer performance which states that software is getting slower more rapidly than hardware is becoming faster." The configurability/performance trade off is true at every level of computing, even down to the function call. That’s why, once the OS is loaded, software is slow to start up. It doesn’t have to dynamically rediscover them every time it starts.Įxtend the “plug and play” concept to software - modular software packages, frameworks, reusable components, dynamic plugins. are computed ahead of time and hardcoded. Embedded systems can start up faster because addresses of its peripherals, resources, accessories etc. There’s a trade-off between that configurability and startup performance. The same mechanisms that allow you to plug in hardware to a desktop and have it “just work” make your computer slower to start up than it could theoretically be. a BIOS using PIO in the case of storage devices) and progressively enabling faster and more complicated modes (e.g. Starting off in backward-compatible hardware modes (eg.
#Phpstorm 10 very slow drivers#
Enumerating buses for hardware, and loading drivers for it all. Talking about specifically boot? Once all other bottlenecks (such as mechanical HDDs or insufficient RAM) are eliminated? Growth comes from using more resource-hungry languages, from using large libraries, and from not spending (‘wasting’) time to find performance bottlenecks. Some of it is invisible programs grow in resource usage in exchange for a shorter time to market. (often, the law of diminishing returns is harsh, but there is progress) Screens have higher resolution, icons are much larger, spell checkers get better, emojis are added, text anti-aliasing is improved, support for perceptual color spaces ais added, video codecs get better compression, but at the price of decompression speed, etc. As computers get faster, programs get more resource-hungry. It seems there’s an equivalent of Marchetti’s constant ( 's_constant: “Marchetti posits that although forms of urban planning and transport may change, and although some live in villages and others in cities, people gradually adjust their lives to their conditions (including location of their homes relative to their workplace) such that the average travel time stays approximately constant”) for the speed of personal computers. The part where you need to do work to really use the new hardware typically is for stuff computers didn’t use to do at all.įor parts where you think “my computer from 10 years ago did that, too, and at the same speed” I think it’s more because software gets written to use the new hardware.
