I'm using renv to manage the specific versions of packages supporting production R code, which is built into rocker-based docker images that are ultimately deployed. In my build logs, I see our initial install2.R --deps=TRUE remotes calls that happen before full package restoration hits the Rstudio Package Manager URL and install binaries super fast. But later calls to restore the exact versions of libraries needed via renv::restore() downloads source from CRAN, which is super slow.
That looked promising, but when I set the override for the latest URL, my renv.lockfile requests for older packages (such as lifecycle 0.2.0) fail with a package not found error. I take it RPSM (at the latest endpoint) only tracks the (near) latest release of packages. While it looks super fast, if I can't restore arbitrary versions that defeats the purpose of renv + docker for my use case.

For several years I am asking myself why Pacman seems to be significant faster than other major packing managers like whatever Debian/Ubuntu/Opensuse are using.
Please note, I am using Archlinux since 2009 as my main driver and due to this short testing phase I am not very good at Archlinux (very good at pacman -Syu, though) or Linux or actually anything except eating Milk with cookies. I tried to do research via a modern internet search machine, but the answers are way too complicated and I am not an engineer. "Dependencies"?!, I am not very good with taxes.
Would you please explain in simple word using train and football analogues (mentioning Lionel Messi helps understanding) why Pacman seems to be significant faster than other major packing managers?
I don't see much difference between pacman and apt-get or yum anymore.
Pacman once was fast, because it was lightweight and simple.
It still somehow is, but since the introduction of hooks, I don't see any significant performance increase any more compared to other package managers, especially on large updates.
Don't get me wrong here: I love ALPM hooks and find them very useful. But everything has its price...
By contrast, Alpine's package manager (apk) does even less than pacman (it has simple triggers but no hooks, APKBUILDs don't offer optdepends and use POSIX sh instead of bash) and as a result it's even faster.
Does anyone know why void's xbps package manager often is stated faster than pacman? Little broad slash stupid question probably, but just seems surpricing to me when considering seemingly has more advanced dependency resolution allowing for e.g partial upgrades. Just curious, and I guess on-topic.
I also read e.g. that what makes apk little faster than xbps(meaning faster than most package managers in general, i'd guess then, e.g. pacman also possibly), is tricks like e.g. it downloads, extracts and feeds hashing algo at same time. Don't know if pacman does same of-course, as this was xbps vs apk, as stated, but sounds nifty(easier said than done of-course ). Hmm, considering pacman's status messages on-screen during it's operation, then doesn't do that, unless i'm mistaken.
Thank you for your multi-angle holistic explanation. This was helpful. I actually did not think about a cognitive bias. Looking at pacman operate is deeply ingrained into my brain, while other packing manager displaying it differently could induce negative emotions (it is scary and potentially demonically wrong), which is known to stretch time.
However, I think you should drop the train, football and Lionel Messi analogues. This is super strange.
Hi all. I'm looking for a way to speed up my R shiny installation setup. I'm using renv for package management but the build takes 30 minutes on average. That is insanely slow, especially considering the small size of the project. I'll note that I've only recently started using R, so I'm used to much faster builds with npm or poetry (javascript and python package managers). Caching works well for repeat builds but my problem is moreso with new builds. Does anyone have any recommendations?
Now comes that most significant part of the new release. We have decided to change the pricing of WP Project Manager Pro. As you will be getting the new modules with premium packages, we had to bring some changes. Besides that, your favorite project management tool is now super fast and saves a lot of your time. We also have plans to bring new features, modules, integrations with the upcoming releases. So, you will love the new version as we are doing now!
Bun is a super fast all-in-one toolkit for JavaScript and TypeScript apps. The beauty of Bun lies in its ability to streamline the development process, making it smoother and more efficient than ever. This is possible because Bun is not just a runtime, it's also a package manager, a bundler, and a test runner. Imagine having a Swiss Army knife for JS development; that's Bun for you.
Bun simplifies this by offering built-in support for these Web standard APIs. Developers can directly use stable fetch, Request, Response, WebSocket and other browser-like APIs without any additional packages. Furthermore, Bun's native implementation of these Web APIs ensures they are faster and more reliable compared to third-party alternatives.
Bun is more than just a runtime; it's an advanced toolkit that includes a powerful package manager. If you've ever found yourself patiently waiting during dependency installations, Bun offers a refreshingly faster alternative. Even if you don't use Bun as a runtime, its built-in package manager can speed up your development workflow.
As you say that you computer is not a super fast calculator you should look for software with a few functions (the fewest possible), and this software meets this requirement, see the next screen-shoot and you will notice it.
Feh is a mode-based image viewer. It is especially aimed at commandline users who need a fast image viewer without huge GUI dependencies, though it can also be started by (graphical) file managers to view an image. It supports filelists, various image sorting modes, image captions and more... Configurable keyboard shortcuts are used to control it.
If i do the update via Gnome Software in the first place, it updates the system and when i reboot, there are updates available again. I dont get that either.
Also Gnome Software is extremely slow. Sometimes taking an hour to upgrade like 10 packages of about 100 Mb or something like that. DNF on the other Hand is super fast, taking a few seconds for that.
This enables users to save time and money on setting up servers for hosting packages for each OS. Packagecloud allows users to set up and update machines faster and with less overhead than ever before.
Now, the specialty of Alpine is its size, and developers wanted a distro that could fit in the memory. Thus, Alpine Linux was created to be as small as possible. Besides, according to Copa, Alpine built its own Linux distro because they wanted it to run from RAM, needed a fast manager that could set up initfs and tmpfs roots, and aimed to provide a low overhead for the installed package database.
Regardless of whether you need to Yank or Push a package, upload multiple packages and skip errors, deploy, distribute, and change the repositories, or simply download or install packages from the public or private repo, packagecloud can handle it all. We have public and private repositories for Alpine Linux which are designed for ultra-fast and secured delivery of your Alpine packages.
In short, packagecloud with its security features is your secured package manager solution. To understand how packagecloud can eliminate worries regarding scaling, consistency, or security of your packages, check out the free trial.Take the trial to see how easily and reliably packages can be distributed throughout your entire organization.
Packages promote the reuse of code as it can be dropped into another application and used easily. Packages are created using a package manager and are usually stored in a repository, like Cloudsmith. The table below details some common packages.
Resolving dependencies in a package is no joke- specifying and resolving the dependencies and relationships between libraries and packages is one of those NP-hard problems. Version constraints on packages mean package managers have to solve a problem equivalent to SAT solving.
The rules around the order and precedence of what repositories to search and what packages to select will determine what packages are used. Generally, packages in the repository itself supersede packages from the upstream.
First, you need to install a Conda-based Python3 distribution.The recommended choice is Mambaforge which not only provides the required Python and Conda commands,but also includes Mamba an extremely fast and robust replacement for the Conda package manager which is highly recommended.The default conda solver is a bit slow and sometimes has issues with selecting the latest package releases.Therefore, we recommend to in any case use Mamba.
I had a problem with the setup, which Priya Goenka helped med with in just a few minuts. She was super fast and gave me an explanation of what I did wrong. Thank you so much.. really saved me some times.
The environment repls run in has long been a static world. We build a pre-baked OS image to fit all our languages. This gives us a lot of leeway to make repls super fast, but the underlying operating system repls run in is completely immutable. To remedy the situation we've been maintaining an ever growing OS image, if users can't install any packages we'll just install every package! As awesome as this sounds it has become a huge burden to maintain. Every new package creates a new exciting way things can break.
Most packages will install very quickly on reasonably fast modern hardware, but there are heavier packages, and a few very large ones. Here are some tips to minimize compilation and installation times on Gentoo.
For some packages, the gui, urlpreview, rss, qt5, pyqt5, dictionary-manager and maybe other USE flags determine QtWebEngine dependency, so it may be useful to watch if theses flags are needed for certain packages or not. 006ab0faaa
