Podcasts about PulseAudio

This week we talk browsers, with coverage of the Servo updates and the new Supporters of Chromium group in the Linux Foundation. The Raspberry Pi has a 16Gb model of the Pi 5, and not everyone is happy about it. KDE Plasma 6.3 has a public beta, Flatpack has released version 1.16, and Mint is on the cusp of releasing version 22.1. For tips we have kshift for quick or automated KDE re-theming, php -S for local php site testing, a quick tar howto, and pipewire-pulse for more pipewire and oulse audio fun.

La dernière version de Kali Linux est sortie aujourd'hui, la distribution GNU/Linux populaire pour l'hacking éthique et les tests de pénétration. Kali Linux 2023.2 apporte de nouvelles fonctionnalités, des outils mis à jour et de nouveaux outils pour améliorer l'expérience des utilisateurs. La principale nouveauté est la prise en charge de PipeWire, qui remplace PulseAudio dans l'édition Xfce de Kali Linux. Cela offre aux utilisateurs une meilleure expérience audio. De plus, l'édition Xfce bénéficie d'une extension appelée GtkHash, qui permet de calculer rapidement les sommes de contrôle des fichiers à l'aide du gestionnaire de fichiers Thunar. Pour les utilisateurs de l'environnement de bureau GNOME, Kali Linux 2023.2 propose la dernière version GNOME 44 et une nouvelle extension appelée Tiling Assistant pour améliorer l'expérience de mosaïque par défaut du bureau. L'offre i3 de Kali Linux a également été améliorée avec un nouvel écran de verrouillage, un menu On/Off et deux variantes de bureau, offrant aux utilisateurs plus de flexibilité dans la gestion des fenêtres. La nouvelle version de Kali Linux comprend également une série de nouveaux outils de piratage, tels que Cilium-cli, Cosign, Evilginx, GoPhish, Humble, Syft, Terraform et Trivy, qui renforcent les capacités des professionnels de la sécurité. En dehors de ces mises à jour, le menu Kali a été amélioré, une nouvelle image VM Hyper-V a été ajoutée et des micrologiciels supplémentaires ont été inclus dans toutes les images ARM. Pour télécharger Kali Linux 2023.2, rendez-vous sur le site officiel, où vous trouverez différentes versions pour les plates-formes ARM, VM, Cloud ou mobiles.

How we found peace with the Linux community's perpetual debates; and our tricks for finding the signal from the noise.

Why we won't see a new Raspberry Pi until 2025, the first steps to Plasma 6 are being taken, and PipeWire gets a major Bluetooth upgrade.

Why this latest release of Fedora misses the mark, and Ubuntu's quiet backing away from ZFS.

Time for your “Normal” computer news! You know. The mainstream stuff. Microsoft, Apple, Linux, Google. That sort of thing.Dive in below, and feel free to listen to the podcast as you go.Apple releases macOS VenturaThis week Apple released the latest revision of their desktop Operating System: “macOS 13 — Ventura”.Among the new features, Stage Manager (a tool for organizing windows on the desktop) and Freeform (a whiteboard-like software for real-time collaboration) seem to be the most standout.Some of the Lunduke Journal Community members had some initial thoughts:“It feels like a refined experience over Monterey. I really like the Continuity Camera that allows you to use your iPhone camera—that's pretty nice and practical. It also has a brand new settings interface that is closer to the iOS experience. That'll be a big change for people.” - microwerx“Installed fine on 3 macs…Intel and Apple Silicon. Already ran into the “how do I do something I already knew how to do” since the system preferences is completely different. Looking forward to using my iPhone as a webcam. Seems more responsive, but that could be a placebo effect.” - leebaseAnd Dan Scott provided a few thoughts of his own:“Everything is as it was before but it does feel a bit faster and less clunky to me.One minor thing that I like that I doubt anyone will really notice or care about, but in the About This Mac window, they went back to the simplified style that we had in earlier versions up to Mavericks. They changed it to include more info with Yosemite. I personally like this.The feature I was waiting for the most was Stage Manager. It's nice, and I like it, but I wish it would show all of your open windows. Instead, it only shows your 5 most recent windows and hides the rest so command+tabbing is still your best bet for cycling through open windows. Running Stage Manager hides the desktop icons, though this can be changed in the system settings, or just click the desktop. I'm not sure there's a real need for something like this, but it's a cool feature. It definitely works better on my external monitor. It just takes up too much space on the Air's little display.I'm not sure how I feel about the new System Settings layout yet. It's very much like iOS now, but I think I still prefer the more traditional System Preferences layout.”You can read more of Dan's first impressions on his Substack.Canonical releases Ubuntu 22.10 “Kinetic Kudu”The latest “will only be supported for a couple months” version of Ubuntu has been released. With some of the major updates being:* The default audio server is now PipeWire instead of PulseAudio.* Ubuntu 22.10 is shipped with the new 5.19 Linux kernel.* GNOME has been updated to include new features and fixes from the latest GNOME release, GNOME 43.* The new Steam snap available on Ubuntu Software includes the latest Mesa.One fascinating tidbit: Canonical does not once mention “Snap” packaging in their full release notes.Microsoft looking at changing how Linux boots, wants to require TPM 2.0Microsoft engineer, Lennart Poettering, has unveiled his (and, assuredly, Microsoft's) desires to tightly intertwine the Linux boot process with TPM 2.0.The TPM (Trusted Platform Module) of course, being created by Microsoft.While there are interesting — and valid — points made by Poettering (creator of systemd), the idea of making the mere act of “booting Linux” reliant on a locked down Microsoft specification… well… no sir, I don't like it.Linux to drop 486 support?This week, Linus Torvalds stated on the Linux Kernel Mailing list:“We got rid of i386 support back in 2012. Maybe it's time to get rid ofi486 support in 2022?”And then he followed that up by stating:“So I *really* don't think i486 class hardware is relevant any more.Yes, I'm sure it exists (Maciej being an example), but from a kerneldevelopment standpoint I don't think they are really relevant.At some point, people have them as museum pieces. They might as wellrun museum kernels.”Are we about to lose 486 support in Linux? Looks like it. Is that a huge deal? Probably not. But I don't like it.No, sir. I don't like it one bit.Microsoft ships ARM Windows computerWant a $600 Windows computer that 32 GB of RAM, 512 GB NVMe drive, a Snapdragon® 8cx Gen 3 CPU, and a thin little form factor?Microsoft will now sell you one.It's intended for developers (it's dubbed the “Windows Dev Kit 2023”), but it still looks rather nice. Even has an ARM native version of Visual Studio and Microsoft 365. And Windows running on this ARM box has WSL2 (Windows Subsystem for Linux)… so you can do all your Linux-y stuff on it.The Lunduke Journal of Technology is a reader-supported publication.

Jitsi https://es.wikipedia.org/wiki/Jitsi. Jesús Cea explica cómo graba. Algo bizarro y que funciona casi de casualidad. Cuando Jesús Cea grababa podcasts https://es.wikipedia.org/wiki/P%C3%B3dcast con un grupo cerrado de gente, la grabación era local cada uno en su máquina. Cada uno grababa su micrófono local y la suma de todos los demás en dos canales distintos. Eso permite tener separación de canales para editar el sonido y, si alguien se olvida de ponerlo, su voz ha quedado grabada en remoto en todos los demás. ALSA https://en.wikipedia.org/wiki/Advanced_Linux_Sound_Architecture. PulseAudio https://es.wikipedia.org/wiki/PulseAudio. PipeWire https://en.wikipedia.org/wiki/PipeWire.

It's episode III, Return of the Email. Everyone says never host your own email, so we're doin it. We just have one last job to complete. Special Guest: Daniel Fore.

The new release of Fedora has more under the hood than you might know. It's a technology-packed release, and nearly all of it is coming to a distro near you. Plus the questions we think the University of Minnesota kernel ban raises, and more.

The University of Minnesota has been banned from the Linux kernel. We'll share the history, the context, and where things stand now around the controversial research that led to the ban. Plus Ubuntu 21.04 is out, and we try WSL's new GUI Linux app support.

We break down the next-level features coming to a Linux near you in just a few weeks.

After all these years, what's made us stick with Linux? Plus the commitment just made by the GNOME team, and some new tools that are changing our game. Special Guest: Drew DeVore.

Gnome 40 has a major redesign, a new version of Kdenlive is out adding some much desired pro features, Matrix has some exciting announcments and we discuss the Solar Winds backdoor and give you some alternatives.

Esta gente de Raspberry OS realmente se ha puesto las pilas. Como ya comenté hace unos días cuando hablé sobre Pi400, Chromium en este equipo me llamó mucho la atención, porque consumía pocos recursos y no solo esto, sino que además la navegación era fluida, tan fluida como que no tenía la sensación de estar en un equipo como la Raspberry Pi. Teniendo en cuenta la limitación de recursos. Y ahora, a los pocos días, liberan una nueva versión de sus sistema operativo, y entre las novedades que trae es una mejora de la navegación, lo que yo he venido a llamar una navegación de vértigo con Raspbperry OS. No solo es esta la única mejora que han incluido en esta nueva versión de Raspberry Pi OS. Hay algunas mejoras adicionales que voy a intentar desgranarte a lo largo de este nuevo episodio del Podcast. Navegación de vértigo con Raspberry OS En que ando metido Como todos los jueves quiero contarte en que ando metido para que sepas lo que encotnrarás en atareao.es. Básicamente me ciño al tema de los tutoriales, porque si has entrado recientemente en tutoriales habrás observado que he lanzado dos nuevos tutoriales. Pi 400PowerShell Sobre la nueva versión de Raspberry OS El pasado 4 de Diciembre la Rasbpberry Pi Foundation liberaron una nueva versión de su sistema operativo, antes conocido como Raspbian y que ahora han renombrado a Raspberry Pi OS. Lo cierto es que son bastantes las novedades que nos trae esta actualización del sistema operativo. Te cuento alguna de ellas, al menos, las que mas me han llamado la atención. Chromium Por supuesto, empiezo por la que mas me llamó la atención en su momento después de probar la Pi 400, que es básicamente el navegador que trae por defecto instalado. En este caso han actualizado a la versión 84 de Chromium. En esta nueva versión han integrado la aceleración de vídeo por hardware con la nueva versión del navegador. Si ya me pareció en su momento que el navegador iba fluido, no quieras imaginar ahora. Básicamente esto lo que permite es una reproducción de vídeo en el navegador de mas calidad, por ejemplo, esto lo notarás cuando visites páginas como YouTube, o en cualquier página que tenga contenido de vídeo. Por supuesto esto cobra mas sentido hoy en día, en la situación en la que nos encontramos en la que estamos utilizando clientes de vídeo conferencia como Google Meet, Microsoft Teams, Zoom, etc. Claro, esto lo podrás aprovechar al máximo si utilizas el cliente de estas plataformas en el propio Chromium. PulseAudio Un detalle que no había observado hasta el momento, por razones obvias, es que Raspberry Pi OS utilizaba hasta esta versión ALSA como interfaz de audio. Sin embargo, en esta nueva versión de Raspberry Pi OS, han decidido reemplazarlo por PulseAudio basándose en las limitaciones de su predecesor. El audio en Linux es simplemente complicado. Existen multitud de soluciones para gestionar el audio, y cada una tiene sus características particulares. Como de costumbre, este es un problema y una realidad en el código abierto, y en particular en el ecosistema Linux. Cuando un desarrollador quiere utilizar una librería de sonido, en este caso, y no le termina de convencer porque le falta una característica que este necesita, en lugar de aportar al código original, simplemente, crea su propia versión. En esto es donde reside la grandeza y una de las problemáticas del ecosiste

This week we're going to dive into the world of Audio in Linux. For the majority of users Pulseaudio seems to do most everything you expect, however, that's not always the case when it comes to more professional audio support. This is why we have projects like Jack and the up and coming PipeWire in hopes of bringing professional and easier audio capability into Linux. We're going to be digging deep into this topic and some news from one particular distro that's looking to push Audio in Linux into the future. In addition we will be covering community feedback and of course we have our popular tips/tricks and software picks. All of this and so much more this week on Destination Linux.

In the DLN Community segment, there was a post in the Destination Linux Network Discourse forum about learning computer programming (https://discourse.destinationlinux.network/t/interested-in-becoming-a-programmer/1828), specifically which languages are worth learning. Eric ignores all that and focuses on the process of actually learning to code and how it's been a series of stops and starts for him. In case you haven't heard, Linux++ (https://frontpagelinux.com/?s=Linux%2B%2B) is now on Front Page Linux (https://frontpagelinux.com). Linux++ is a weekly dive into the major topics, events, and headlines throughout the Linux world published by Eric Londo (https://frontpagelinux.com/author/eric-londo/). Eric is an environmental engineer with a passion in software development, the open-source software community, and especially the GNU/Linux OS. His take on the events of the week are in-depth, concise and well researched. It's an excellent resource for all things Linux and Open Source and we highly recommend checking it out. On Hardware Addicts episode 8 (https://hardwareaddicts.org/8) they discuss new AMD laptop processors featuring a lower TDP (thermal design power (https://en.wikipedia.org/wiki/Thermal_design_power)) which promises lower heat output and better battery life. This gets us thinking about the race to the middle that the ARM and x86 CPU architectures seem to be engaged in. Also on Hardware Addicts episode 8 (https://hardwareaddicts.org/8), the topic of USB audio devices was discussed which led Nate to wonder if having a hardware solution for audio is a better choice than controlling things in software with the likes of PulseAudio. That's all for this episode.

This episode was brought to you by Headlines vBSDCon CFP closed April 29th (https://easychair.org/conferences/?conf=vbsdcon2017) EuroBSDCon CFP closes April 30th (https://2017.eurobsdcon.org/2017/03/13/call-for-proposals/) Developer Commentary: Philosophy, Evolution of TrueOS/Lumina, and Other Thoughts. (https://www.trueos.org/blog/developer-commentary-philosophy-evolution-trueoslumina-thoughts/) Philosophy of Development No project is an island. Every single project needs or uses some other external utility, library, communications format, standards compliance, and more in order to be useful. A static project is typically a dead project. A project needs regular upkeep and maintenance to ensure it continues to build and run with the current ecosystem of libraries and utilities, even if the project has no considerable changes to the code base or feature set. “Upstream” decisions can have drastic consequences on your project. Through no fault of yours, your project can be rendered obsolete or broken by changing standards in the global ecosystem that affect your project's dependencies. Operating system focus is key. What OS is the project originally designed for? This determines how the “upstream” dependencies list appears and which “heartbeat” to monitor. Evolution of PC-BSD, Lumina, and TrueOS. With these principles in mind – let's look at PC-BSD, Lumina, and TrueOS. PC-BSD : PC-BSD was largely designed around KDE on FreeBSD. KDE/Plasma5 has been available for Linux OS's for well over a year, but is still not generally available on FreeBSD. It is still tucked away in the experimental “area51” repository where people are trying to get it working first. Lumina : As a developer with PC-BSD for a long time, and a tester from nearly the beginning of the project, I was keenly aware the “winds of change” were blowing in the open-source ecosystem. TrueOS : All of these ecosystem changes finally came to a head for us near the beginning of 2016. KDE4 was starting to deteriorate underneath us, and the FreeBSD “Release” branch would never allow us to compete with the rate of graphics driver or standards changes coming out of the Linux camp. The Rename and Next Steps With all of these changes and the lack of a clear “upgrade” path from PC-BSD to the new systems, we decided it was necessary to change the project itself (name and all). To us, this was the only way to ensure people were aware of the differences, and that TrueOS really is a different kind of project from PC-BSD. Note this was not a “hostile takeover” of the PC-BSD project by rabid FreeBSD fanatics. This was more a refocusing of the PC-BSD project into something that could ensure longevity and reliability for the foreseeable future. Does TrueOS have bugs and issues? Of course! That is the nature of “rolling” with upstream changes all the time. Not only do you always get the latest version of something (a good thing), you also find yourself on the “front line” for finding and reporting bugs in those same applications (a bad thing if you like consistency or stability). What you are also seeing is just how much “churn” happens in the open-source ecosystem at any given time. We are devoted to providing our users (and ourselves – don't forget we use TrueOS every day too!) a stable, reliable, and secure experience. Please be patient as we continue striving toward this goal in the best way possible, not just doing what works for the moment, but the project's future too. Robert Mustacchi: Excerpts from The Soft Ring Cycle #1 (https://www.youtube.com/watch?v=vnD10WQ2930) The author of the “Turtles on the Wire” post we featured the other week, is back with a video. Joyent has started a new series of lunchtime technical discussions to share information as they grow their engineering team This video focuses on the network stack, how it works, and how it relates to virtualization and multi-tenancy Basically, how the network stack on IllumOS works when you have virtual tenants, be they virtual machines or zones The video describes the many layers of the network stack, how they work together, and how they can be made to work quickly It also talks about the trade-offs between high throughput and low latency How security is enforced, so virtual tenants cannot send packets into VLANs they are not members of, or receive traffic that they are not allowed to by the administrator How incoming packets are classified, and eventually delivered to the intended destination How the system decides if it has enough available resources to process the packet, or if it needs to be dropped How interface polling works on IllumOS (a lot different than on FreeBSD) Then the last 20 minutes are about how the qemu interface of the KVM hypervisor interfaces with the network stack We look forward to seeing more of these videos as they come out *** Forcing the password gropers through a smaller hole with OpenBSD's PF queues (http://bsdly.blogspot.com/2017/04/forcing-password-gropers-through.html) While preparing material for the upcoming BSDCan PF and networking tutorial (http://www.bsdcan.org/2017/schedule/events/805.en.html), I realized that the pop3 gropers were actually not much fun to watch anymore. So I used the traffic shaping features of my OpenBSD firewall to let the miscreants inflict some pain on themselves. Watching logs became fun again. The actual useful parts of this article follow - take this as a walkthrough of how to mitigate a wide range of threats and annoyances. First, analyze the behavior that you want to defend against. In our case that's fairly obvious: We have a service that's getting a volume of unwanted traffic, and looking at our logs the attempts come fairly quickly with a number of repeated attempts from each source address. I've written about the rapid-fire ssh bruteforce attacks and their mitigation before (and of course it's in The Book of PF) as well as the slower kind where those techniques actually come up short. The traditional approach to ssh bruteforcers has been to simply block their traffic, and the state-tracking features of PF let you set up overload criteria that add the source addresses to the table that holds the addresses you want to block. For the system that runs our pop3 service, we also have a PF ruleset in place with queues for traffic shaping. For some odd reason that ruleset is fairly close to the HFSC traffic shaper example in The Book of PF, and it contains a queue that I set up mainly as an experiment to annoy spammers (as in, the ones that are already for one reason or the other blacklisted by our spamd). The queue is defined like this: queue spamd parent rootq bandwidth 1K min 0K max 1K qlimit 300 yes, that's right. A queue with a maximum throughput of 1 kilobit per second. I have been warned that this is small enough that the code may be unable to strictly enforce that limit due to the timer resolution in the HFSC code. But that didn't keep me from trying. Now a few small additions to the ruleset are needed for the good to put the evil to the task. We start with a table to hold the addresses we want to mess with. Actually, I'll add two, for reasons that will become clear later: table persist counters table persist counters The rules that use those tables are: block drop log (all) quick from pass in quick log (all) on egress proto tcp from to port pop3 flags S/SA keep state (max-src-conn 2, max-src-conn-rate 3/3, overload flush global, pflow) set queue spamd pass in log (all) on egress proto tcp to port pop3 flags S/SA keep state (max-src-conn 5, max-src-conn-rate 6/3, overload flush global, pflow) The last one lets anybody connect to the pop3 service, but any one source address can have only open five simultaneous connections and at a rate of six over three seconds. The results were immediately visible. Monitoring the queues using pfctl -vvsq shows the tiny queue works as expected: queue spamd parent rootq bandwidth 1K, max 1K qlimit 300 [ pkts: 196136 bytes: 12157940 dropped pkts: 398350 bytes: 24692564 ] [ qlength: 300/300 ] [ measured: 2.0 packets/s, 999.13 b/s ] and looking at the pop3 daemon's log entries, a typical encounter looks like this: Apr 19 22:39:33 skapet spop3d[44875]: connect from 111.181.52.216 Apr 19 22:39:33 skapet spop3d[75112]: connect from 111.181.52.216 Apr 19 22:39:34 skapet spop3d[57116]: connect from 111.181.52.216 Apr 19 22:39:34 skapet spop3d[65982]: connect from 111.181.52.216 Apr 19 22:39:34 skapet spop3d[58964]: connect from 111.181.52.216 Apr 19 22:40:34 skapet spop3d[12410]: autologout time elapsed - 111.181.52.216 Apr 19 22:40:34 skapet spop3d[63573]: autologout time elapsed - 111.181.52.216 Apr 19 22:40:34 skapet spop3d[76113]: autologout time elapsed - 111.181.52.216 Apr 19 22:40:34 skapet spop3d[23524]: autologout time elapsed - 111.181.52.216 Apr 19 22:40:34 skapet spop3d[16916]: autologout time elapsed - 111.181.52.216 here the miscreant comes in way too fast and only manages to get five connections going before they're shunted to the tiny queue to fight it out with known spammers for a share of bandwidth. One important takeaway from this, and possibly the most important point of this article, is that it does not take a lot of imagination to retool this setup to watch for and protect against undesirable activity directed at essentially any network service. You pick the service and the ports it uses, then figure out what are the parameters that determine what is acceptable behavior. Once you have those parameters defined, you can choose to assign to a minimal queue like in this example, block outright, redirect to something unpleasant or even pass with a low probability. 64-bit inodes (ino64) Status Update and Call for Testing (https://lists.freebsd.org/pipermail/freebsd-fs/2017-April/024684.html) Inodes are data structures corresponding to objects in a file system, such as files and directories. FreeBSD has historically used 32-bit values to identify inodes, which limits file systems to somewhat under 2^32 objects. Many modern file systems internally use 64-bit identifiers and FreeBSD needs to follow suit to properly and fully support these file systems. The 64-bit inode project, also known as ino64, started life many years ago as a project by Gleb Kurtsou (gleb@). After that time several people have had a hand in updating it and addressing regressions, after mckusick@ picked up and updated the patch, and acted as a flag-waver. Overview : The ino64 branch extends the basic system types inot and devt from 32-bit to 64-bit, and nlink_t from 16-bit to 64-bit. Motivation : The main risk of the ino64 change is the uncontrolled ABI breakage. Quirks : We handled kinfo sysctl MIBs, but other MIBs which report structures depended on the changed type, are not handled in general. It was considered that the breakage is either in the management interfaces, where we usually allow ABI slip, or is not important. Testing procedure : The ino64 project can be tested by cloning the project branch from GitHub or by applying the patch to a working tree. New kernel, old world. New kernel, new world, old third-party applications. 32bit compat. Targeted tests. NFS server and client test Other filesystems Test accounting Ports Status with ino64 : A ports exp-run for ino64 is open in PR 218320. 5.1. LLVM : LLVM includes a component called Address Sanitizer or ASAN, which triesto intercept syscalls, and contains knowledge of the layout of many system structures. Since stat and lstat syscalls were removed and several types and structures changed, this has to be reflected in the ASAN hacks. 5.2. lang/ghc : The ghc compiler and parts of the runtime are written in Haskell, which means that to compile ghc, you need a working Haskell compiler for bootstrap. 5.3. lang/rust Rustc has a similar structure to GHC, and same issue. The same solution of patching the bootstrap was done. Next Steps : The tentative schedule for the ino64 project: 2017-04-20 Post wide call for testing : Investigate and address port failures with maintainer support 2017-05-05 Request second exp-run with initial patches applied : Investigate and address port failures with maintainer support 2017-05-19 Commit to HEAD : Address post-commit failures where feasible *** News Roundup Sing, beastie, sing! (http://meka.rs/blog/2017/01/25/sing-beastie-sing/) FreeBSD digital audio workstation, or DAW for short, is now possible. At this very moment it's not user friendly that much, but you'll manage. What I want to say is that I worked on porting some of the audio apps to FreeBSD, met some other people interested in porting audio stuff and became heavily involved with DrumGizmo - drum sampling engine. Let me start with the basic setup. FreeBSD doesn't have hard real-time support, but it's pretty close. For the needs of audio, FreeBSD's implementation of real-time is sufficient and, in my opinion, superior to the one you can get on Linux with RT path (which is ugly, not supported by distributions and breaks apps like VirtualBox). As default install of FreeBSD is concerned with real-time too much, we have to tweak sysctl a bit, so append this to your /etc/sysctl.conf: kern.timecounter.alloweddeviation=0 hw.usb.uaudio.buffer_ms=2 # only on -STABLE for now hw.snd.latency=0 kern.coredump=0 So let me go through the list. First item tells FreeBSD how many events it can aggregate (or wait for) before emitting them. The reason this is the default is because aggregating events saves power a bit, and currently more laptops are running FreeBSD than DAWs. Second one is the lowest possible buffer for USB audio driver. If you're not using USB audio, this won't change a thing. Third one has nothing to do with real-time, but dealing with programs that consume ~3GB of RAM, dumping cores around made a problem on my machine. Besides, core dumps are only useful if you know how to debug the problem, or someone is willing to do that for you. I like to not generate those files by default, but if some app is constantly crashing, I enable dumps, run the app, crash it, and disable dumps again. I lost 30GB in under a minute by examining 10 different drumkits of DrumGizmo and all of them gave me 3GB of core file, each. More setup instructions follow, including jackd setup and PulseAudio using virtual_oss. With this setup I can play OSS, JACK and PulseAudio sound all at the same time, which I was not able to do on Linux. FreeBSD 11 Unbound DNS server (https://itso.dk/?p=499) In FreeBSD, there is a built-in DNS server called Unbound. So why would run a local DNS server? I am in a region where internet traffic is still a bit expensive, that also implies slow, and high response times. To speed that a up a little, you can use own DNS server. It will speed up because for every homepage you visit, there will be several hooks to other domains: commercials, site components, and links to other sites. These, will now all be cached locally on your new DNS server. In my case I use an old PC-Engine Alix board for my home DNS server, but you can use almost everything, Raspberry Pi, old laptop/desktop and others. As long as it runs FreeBSD. Goes into more details about what commands to run and which services to start Try it out if you are in a similar situation *** Why it is important that documentation and tutorials be correct and carefully reviewed (https://arxiv.org/pdf/1704.02786.pdf) A group of researchers found that a lot of online web programming tutorials contain serious security flaws. They decided to do a research project to see how this impacts software that is written possibly based on those tutorials. They used a number of simple google search terms to make a list of tutorials, and manually audited them for common vulnerabilities. They then crawled GitHub to find projects with very similar code snippets that might have been taken from those tutorials. The Web is replete with tutorial-style content on how to accomplish programming tasks. Unfortunately, even top-ranked tutorials suffer from severe security vulnerabilities, such as cross-site scripting (XSS), and SQL injection (SQLi). Assuming that these tutorials influence real-world software development, we hypothesize that code snippets from popular tutorials can be used to bootstrap vulnerability discovery at scale. To validate our hypothesis, we propose a semi-automated approach to find recurring vulnerabilities starting from a handful of top-ranked tutorials that contain vulnerable code snippets. We evaluate our approach by performing an analysis of tens of thousands of open-source web applications to check if vulnerabilities originating in the selected tutorials recur. Our analysis framework has been running on a standard PC, analyzed 64,415 PHP codebases hosted on GitHub thus far, and found a total of 117 vulnerabilities that have a strong syntactic similarity to vulnerable code snippets present in popular tutorials. In addition to shedding light on the anecdotal belief that programmers reuse web tutorial code in an ad hoc manner, our study finds disconcerting evidence of insufficiently reviewed tutorials compromising the security of open-source projects. Moreover, our findings testify to the feasibility of large-scale vulnerability discovery using poorly written tutorials as a starting point The researchers found 117 vulnerabilities, of these, at least 8 appear to be nearly exact copy/pastes of the tutorials that were found to be vulnerable. *** 1.3.0 Development Preview: New icon themes (https://lumina-desktop.org/1-3-0-development-preview-new-icon-themes/) As version 1.3.0 of the Lumina desktop starts getting closer to release, I want to take a couple weeks and give you all some sneak peaks at some of the changes/updates that we have been working on (and are in the process of finishing up). New icon theme (https://lumina-desktop.org/1-3-0-development-preview-new-icon-themes/) Material Design Light/Dark There are a lot more icons available in the reference icon packs which we still have not gotten around to renaming yet, but this initial version satisfies all the XDG standards for an icon theme + all the extra icons needed for Lumina and it's utilities + a large number of additional icons for application use. This highlights one the big things that I love about Lumina: it gives you an interface that is custom-tailored to YOUR needs/wants – rather than expecting YOU to change your routines to accomodate how some random developer/designer across the world thinks everybody should use a computer. Lumina Media Player (https://lumina-desktop.org/1-3-0-development-preview-lumina-mediaplayer/) This is a small utility designed to provide the ability for the user to play audio and video files on the local system, as well as stream audio from online sources. For now, only the Pandora internet radio service is supported via the “pianobar” CLI utility, which is an optional runtime dependency. However, we hope to gradually add new streaming sources over time. For a long time I had been using another Pandora streaming client on my TrueOS desktop, but it was very fragile with respect to underlying changes: LibreSSL versions for example. The player would regularly stop functioning for a few update cycles until a version of LibreSSL which was “compatible” with the player was used. After enduring this for some time, I was finally frustrated enough to start looking for alternatives. A co-worker pointed me to a command-line utility called “pianobar“, which was also a small client for Pandora radio. After using pianobar for a couple weeks, I was impressed with how stable it was and how little “overhead” it required with regards to extra runtime dependencies. Of course, I started thinking “I could write a Qt5 GUI for that!”. Once I had a few free hours, I started writing what became lumina-mediaplayer. I started with the interface to pianobar itself to see how complicated it would be to interact with, but after a couple days of tinkering in my spare time, I realized I had a full client to Pandora radio basically finished.

We're back from AsiaBSDCon! This week we'll be chatting with Gleb Kurtsou about some a filesystem-level encryption utility called PEFS. After that, we'll give you a step by step guide on how to actually use it. There's also the usual round of your questions and we've got a lot of news to catch up on, so stay tuned to BSD Now - the place to B.. SD. This episode was brought to you by Headlines Using OpenSSH Certificate Authentication (http://neocri.me/documentation/using-ssh-certificate-authentication/) SSH has a not-so-often-talked-about authentication option in addition to passwords and keys: certificates - you can add certificates to any current authentication method you're using They're not really that complex, there just isn't a lot of documentation on how to use them - this post tries to solve that There's the benefit of not needing a knownhosts file or authorizedusers file anymore The post goes into a fair amount of detail about the differences, advantages and implications of using certificates for authentication *** Back to FreeBSD, a new series (http://www.duckland.org/2014/03/back-to-freebsd-aka-day-1#more) Similar to the "FreeBSD Challenge" blog series, one of our listeners will be writing about his switching BACK to FreeBSD journey "So, a long time ago, I had a box which was running FreeBSD 4, running on a Pentium. 14 years later, I have decided to get back into FreeBSD, now at FreeBSD 10" He's starting off with PCBSD since it's easy to get working with dual graphics Should be a fun series to follow! *** OpenBSD's recent experiments in package building (http://undeadly.org/cgi?action=article&sid=20140307130554) If you'll remember back to our poudriere tutorial (http://www.bsdnow.tv/tutorials/poudriere), it lets you build FreeBSD binary packages in bulk - OpenBSD's version is called dpb (http://www.bsdnow.tv/tutorials/dpb) Marc Espie recently got some monster machines in russia to play with to help improve scaling of dpb on high end hardware This article goes through some of his findings and plans for future versions that increase performance We'll be showing a tutorial of dpb on the show in a few weeks *** Securing FreeBSD with 2FA (http://jafdip.com/securing-freebsd-2fa-two-factor-authentication/) So maybe you've set up two-factor authentication with gmail or twitter, but have you done it with your BSD box? This post walks us through the process of locking down an ssh server (http://www.bsdnow.tv/tutorials/ssh-tmux) with 2FA With just a mobile phone and a few extra tools, you can enable two-factor auth on your BSD box and have just that little extra bit of protections *** Interview - Gleb Kurtsou - gleb.kurtsou@gmail.com (mailto:gleb.kurtsou@gmail.com) PEFS (security audit results here (https://defuse.ca/audits/pefs.htm)) Tutorial Filesystem-based encryption with PEFS (http://www.bsdnow.tv/tutorials/pefs) News Roundup BSDCan 2014 registration (https://www.bsdcan.org/2014/registration.php) Registration is finally open! The prices are available along with a full list of presentations Tutorial sessions for various topics as well You have to go *** Big changes for OpenBSD 5.6 (http://undeadly.org/cgi?action=article&sid=20140314080734) Although 5.5 was just frozen and the release process has started, 5.6 is already looking promising OpenBSD has, for a long time, included a heavily-patched version of Apache based on 1.3 They've also imported nginx into base a few years ago, but now have finally removed Apache Sendmail is also no longer the default MTA, OpenSMTPD is the new default (http://undeadly.org/cgi?action=article&sid=20140313052817) Will BIND be removed next? Maybe so (http://marc.info/?l=openbsd-cvs&m=139492163427518&w=2) They've also discontinued the hp300, mvme68k and mvme88k ports *** Getting to know your portmgr lurkers (http://blogs.freebsdish.org/portmgr/2014/03/11/getting-to-know-your-portmgr-lurker-alexy-dokuchaev/) The "getting to know your portmgr" series makes its return This time we get to talk with danfe@ (probably most known for being the nVidia driver maintainer, but he does a lot with ports) How he got into FreeBSD? He "wanted a unix system that I could understand and that would not get bloated as time goes by" Mentions why he's still heavily involved with the project and lots more *** PCBSD weekly digest (http://blog.pcbsd.org/2014/03/pc-bsd-weekly-feature-digest-20/) Work has started to port Pulseaudio to PCBSD 10.0.1 There's a new "pc-mixer" utility being worked on for sound management as well New PBIs, GNOME/Mate updates, Life Preserver fixes and a lot more PCBSD 10.0.1 was released (http://blog.pcbsd.org/2014/03/pc-bsd-weekly-feature-digest-21-pcbsd-10-0-1-released/) too *** Feedback/Questions Alex writes in (http://slexy.org/view/s2QwjHkL2n) Ben writes in (http://slexy.org/view/s2wLGlHF15) Nick writes in (http://slexy.org/view/s21JsgRjMU) Sami writes in (http://slexy.org/view/s2UX4sYdHy) Christopher writes in (http://slexy.org/view/s26z60Qd6z) ***
