  • Michael Meeks' slides (PDF) on history of LibreOffice
  • OOXML / PDF Digital Signing in Draw and elsewhere conference talk

    Today I gave a OOXML / PDF Digital Signing in Draw and elsewhere talk at the LibreOffice Conference 2020. The (virtual) room was well-crowded — somehow people find digital signatures interesting. Wink

    It contains an overview of the ODF/OOXML/PDF signing feature set and also details the latest improvements, like visible PDF signing.

    I expect quite some other slides from other Collaborans and the wider community will be available on Planet, don’t miss them.

  • Not perfect, but close.

    I installed Ultimate Edition 6.7 Developer now twice. I am thinking my daily driver, I am a developer. This is a LTS (Long Term Supported) release, I will let you know I have re-built it. I want you to enjoy it with me if you are a developer. A common user, I do not suggest it. You will find very few games, yes there are a few. Heavily strewn with applications to develop. We will move forward. I like to think of this as my base.

    I do have a tighter one coming: 2098167 extents written (4,097 MB), let me do my job. I canceled it.
    19% 818MB 227.6KB/s 4:12:52 ETA I won’t deal with that, uploading to our servers. 13 minutes v/s 4 hours… Once on our servers I can pass it around in a minute, multiple servers. 1% 65MB 1.1MB/s 1:04:47 ETA Should have left it alone. Sourceforge Hammered? Something new drop today? My internet is faster then SourceForge today.

  • Specify Form-Factors in Your Librem 5 Apps | Adrien Plazas

    While more and more applications are being redesigned to take smartphones like the Librem 5 into account, PureOS still offers lots of desktop applications which are not ready to run on such devices yet.

    As a user you want to know which applications are relevant to install, so PureOS Store will by default only present mobile-ready applications, while still letting you opt-into showing all applications to take full advantage of the Librem 5’s convergeant docked mode. As a user you also want to know which applications are relevant to run at a given time, so Phosh will let you run desktop-only applications only when the phone is docked.

    This requires the applications to provide some information on which form-factors they can handle, if you are an application developer and you want your applications to work as expected on the Librem 5, please provide the relevant information as shown below.

  • NENA is a sweet little puzzle action-adventure where you control a robot with telepathy | GamingOnLinux

    NENA is a new adventure following Botley, a robot that wants more than a life disposing of self-aware robotic boxes.

    At some point in the far future, robotics and AI are so advanced that we had to pass laws to give them full awareness of life and it all seems as terrible as you can imagine. NENA might not look like much but it's quite a surprising little adventure with some amusing interactions.

    In this short, top-down action-puzzler you start when you're first turned on, only to be told right away that your only reason for "living" is to put little boxes into a furnace to dispose of them — forever. The problem is, you're self-aware, you know about the world and the boxes you're supposed to burn to ashes are also aware. Thankfully, the boxes were programmed to like everything, even pain…

  • Steampunk grid-based dungeon-crawler Vaporum: Lockdown is out for Linux now | GamingOnLinux

    Vaporum: Lockdown is a rather gorgeous steampunk dungeon crawler from Fatbot Games, which serves as a prequel to the original and it's now supported on Linux.

    In this latest release you follow the story of Ellie Teller, a scientist who is a part of a mysterious research project in the middle of an ocean. After disastrous events, she struggles to survive and escape the tower of Arx Vaporum. While it's a prequel, the developer noted that it "expands on everything that made the original game good".

  • NumPad Rebooted

    If you use the PageUp key a lot (e.g. accessing shell history) and instead of hitting PageUp you hit NumLock? and then it happens several times? the solution for me was to remap the NumLock key to become another PageUp.

    This is for systems using Udev (which is now part of systemd), and a USB or PS/2 keyboard; I am not sure this is feasible for laptops, since as far as I know, on a laptop keyboard switching the Numpad on/off can be useful, gives you more keys on the already cramped keyboard.

  • How to use the Apache web server to install and configure a website - TechRepublic

    Every so often I find it good to take a step back and go through the basics. It not only helps to ground me as a tech writer, but it helps a lot of people who are just learning the ropes of whatever piece of technology I'm talking about.

    This time it's all about the Apache web server, a piece of software that's been around for decades, happily serving up small and large websites without fail. Apache works seamlessly with MySQL, PHP, and a host of other packages, so you can serve up simple static or incredibly dynamic websites.

  • UKUI desktop – SparkyLinux

  • XFS Patches For Linux 5.10 Delays The Year 2038 Problem To 2486

    XFS patches for Linux 5.10 submitted by XFS file system maintainer Darrick J. Wong will delay the year 2038 problem for XFS by an additional 448 years. That should be enough to come up with a real long-term solution. The time-stamp patches were submitted as a part of a larger patch-set with a "large pile of new stuff".

    [...]

    The code widening the inode time-stamps gives us an additional 448 years to come up with a more long-term solution. It may be of interest that the XFS epoch starts at December 1901, not January 1970 like most other Unix time-stamps.

    Another notable change in the patch-set adds inode btree counts to the allocation groups. That speeds up file system mounting and adds a little more metadata redundancy. There's also a mention of fixing "some math errors in the realtime allocator" in the patches comments.

    It's not confirmed that the patches will make it into Linux 5.10, but it seems very likely. The merge window is open and Darrick J. Wong, employed by Oracle, is the XFS maintainer so XFS patches from him are merged as a matter of routine.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
