Resurrect Your Old PC
Resurrect your old PCs Resurrect your old PC Nostalgic for your old beige boxes? Don’t let them gather dust! Proprietary OSes force users to upgrade hardware much sooner than necessary: Neil Bothwick highlights some great ways to make your pensioned-off PCs earn their keep. ardware performance is constantly improving, and it is only natural to want the best, so we upgrade our H system from time to time and leave the old ones behind, considering them obsolete. But you don’t usually need the latest and greatest, it was only a few years ago that people were running perfectly usable systems on 500MHz CPUs and drooling over the prospect that a 1GHz CPU might actually be available quite soon. I can imagine someone writing a similar article, ten years from now, about what to do with that slow, old 4GHz eight-core system that is now gathering dust. That’s what we aim to do here, show you how you can put that old hardware to good use instead of consigning it to the scrapheap. So what are we talking about when we say older computers? The sort of spec that was popular around the turn of the century. OK, while that may be true, it does make it seem like we are talking about really old hardware. A typical entry-level machine from six or seven years ago would have had something like an 800MHz processor, Pentium 3 or similar, 128MB of RAM and a 20- 30GB hard disk. The test rig used for testing most of the software we will discuss is actually slightly lower spec, it has a 700MHz Celeron processor, because that’s what I found in the pile of computer gear I never throw away in my loft, right next to my faithful old – but non-functioning – Amiga 4000. -
CNTR: Lightweight OS Containers
CNTR: Lightweight OS Containers Jorg¨ Thalheim, Pramod Bhatotia Pedro Fonseca Baris Kasikci University of Edinburgh University of Washington University of Michigan Abstract fundamental to achieve high efficiency in virtualized datacenters and enables important use-cases, namely Container-based virtualization has become the de-facto just-in-time deployment of applications. Moreover, standard for deploying applications in data centers. containers significantly reduce operational costs through However, deployed containers frequently include a higher consolidation density and power minimization, wide-range of tools (e.g., debuggers) that are not required especially in multi-tenant environments. Because of all for applications in the common use-case, but they these advantages, it is no surprise that containers have seen are included for rare occasions such as in-production wide-spread adoption by industry, in many cases replacing debugging. As a consequence, containers are significantly altogether traditional virtualization solutions [17]. larger than necessary for the common case, thus increasing the build and deployment time. Despite being lightweight, deployed containers often include a wide-range of tools such as shells, editors, CNTR1 provides the performance benefits of lightweight coreutils, and package managers. These additional tools containers and the functionality of large containers by are usually not required for the application’s core function splitting the traditional container image into two parts: the — the common operational use-case — but they are “fat” image — containing the tools, and the “slim” image included for management, manual inspection, profiling, — containing the main application. At run-time, CNTR and debugging purposes [64]. In practice, this significantly allows the user to efficiently deploy the “slim” image and increases container size and, in turn, translates into then expand it with additional tools, when and if necessary, slower container deployment and inefficient datacenter by dynamically attaching the “fat” image. -

MIT 150 | Project Athena - X Window System Users and Developers Conference, Day 1 [3/4] 1/14/1987
MIT 150 | Project Athena - X Window System Users and Developers Conference, Day 1 [3/4] 1/14/1987 [MUSIC PLAYING] PALAY: My name is Andrew Palay I work at the Information Technology Center at Carnegie Mellon University. For those who don't know, the Information Technology Center is a joint project between Carnegie Mellon University and IBM. It also has some funding from the National Science Foundation. This talk is going to cover the Andrew toolkit. I'd like to begin this talk by providing a short example of what the toolkit's all about. In particular, how I made this slide. And actually some of the other slides. So I basically had the editor. In this case, I had typed in the text. And I selected a spot of the text and essentially asked to add a raster. This particular place, I added a raster. This object that we add into these will be referred to, and are referred to by the toolkit, as insets. The inset comes up as its default size, given that I've added nothing to it. I then request to read a known raster from the file, And this point, in this case the ITC logo. If you note, the actual inset itself hasn't increased in size to accommodate the raster image. The user has control over that size, can actually make it larger or smaller. Later in the talk, another slide you will see actually has a drawing. In this case, I selected areas that I wanted the drawing, actually created the drawing in place. -

Contributor the vast majority of you probably know me (or have at least seen me H around the forums), I feel that I should take a moment to introduce myself. My name is Daniel Griffiths, and I am a 26-year-old independent contractor in Delaware, US. Throughout my life, I have wandered through various UNIX/Linux systems including (but not limited to) MINIX, RedHat, Mandrake, Slackware, Gentoo, Debian, and even two home made distributions based on Linux From Scratch. I finally found Arch in 2007 and instantly fell in love with its elegant simplicity. Some of our more attentive readers may note that Arch already has a monthly newsletter. With the existence of the aformentioned newsletter, what is the point of adding another news medium to the mix? Fear not, newsletter readers, I have no intention of letting Arch User Magazine take the place of the newsletter. In fact, Arch User Magazine and the newsletter are intended to fill two very different needs in the Arch community. -

In the following chapters, we display graphs of the data. The data is provided in tabular form for more science in the end of the document.
