      • Introducing master_me, a mastering plugin for live broadcasting

        master_me is a new free/libre plugin and standalone application to automatically adjust the loudness of the audio in your live streams.

        It has been designed to be stupid easy when you need one button to do it right. If you use something like Ardour as a mixing desk, all you have to do is set up input levels and routing (e.g. from Ardour to OBS), then drop the master_me plugin into the processor box of the master bus, click a preset — and you are pretty much ready to go.

        The plugin/program comes with presets for YouTube, Apple Podcasts, EBU R128, and general speech and music. If you need more, you can switch to the expert mode and get full access to all the tools that build up the “one click” experience under the hood: a leveler, two types of a compressor, a limiter, an EQ, and more.

      • uni TorontoThe problem of network tunnels and (asymmetric) routing

        Your life is generally easier if the external machine E is not directly reachable from the Internet and instead you have to go through a different IP address to reach it (such as a gateway); often this means you have no conflicting routes, since you can't reach E's (private) IP address except through the tunnel. Of course you may have a similar problem if you need to manage the gateway machine itself, since that machine definitely has a public IP address.

        I really wanted the name of this article does not sound dramatically but I was not able to invent any other title … none the less the wireless/WiFi topic can be problematic on the FreeBSD land. Its a known feat of FreeBSD that is does its job best at the server room and that laptop/desktop based configurations tend to need some ‘love’ to be usable. The worst thing of that part is lack of WiFi kernel drivers at all or slower then possible speed like 802.11g on 802.11n capable chips – often as old as 11 years old Intel Ultimate-N 6300 450Mbps card that runs only at 802.11g speed on FreeBSD. The aim of this article is to show you the alternatives and possibilities when it comes to wireless and/or WiFi problems that you may encounter on FreeBSD UNIX system.

        Shortly after I started HTMHell a similar thing happened. Every other website seemed to have inaccessible buttons. While this can be explained by the Baader–Meinhof phenomenon, there’s actually data that confirms my feeling.

      • Red HatGCC's new fortification level: The gains and costs

        This article describes a new level of fortification supported in GCC. This new level detects more buffer overflows and bugs which mitigates security issues in applications at run time.

        C programs routinely suffer from memory management problems. For several years, a _FORTIFY_SOURCE preprocessor macro inserted error detection to address these problems at compile time and run time. To add an extra level of security, _FORTIFY_SOURCE=3 has been in the GNU C Library (glibc) since version 2.34. I described its mechanisms in my previous blog post, Broadening compiler checks for buffer overflows in _FORTIFY_SOURCE. There has been compiler support for this builtin in Clang for some time. Compiler support has also been available for GCC since the release of version 12 in May 2022. The new mitigation should be available in GNU/Linux distributions with packaged GCC 12.

        The following sections discuss two principal gains from this enhanced level of security mitigation and the resulting impact on applications.

      • Tourism in India for Debconf 23

        I had shared a while back that I would write a bit about tourism as Debconf or Annual Debian Conference will happen in India next year around this time. I was supposed to write it in the FAQ but couldn’t find a place or a corner where I could write it. There are actually two things that people need to be aware of. The one thing that people need to be very aware of is food poisoning or Delhi Belly. This is a far too common sight that I have witnessed especially with westerners when they come to visit India. I am somewhat shocked that it hasn’t been shared in the FAQ but then perhaps we cannot cover all the bases therein. I did find this interesting article and would recommend the suggestions given in it wholeheartedly. I would suggest people coming to India to buy and have purifying water tablets with them if they decide to stay back and explore India.

        Now the problem with tourism is, that one can have as much tourism as one wants. One of the unique ways I found some westerners having the time of their life is buying an Indian Rickshaw or Tuk-Tuk and traveling with it. A few years ago, when I was more adventourous-spirited I was able to meet a few of them. There is also the Race with Rickshaws that happens in Rajasthan and you get to see about 10 odd cities in and around Rajasthan state and get to see the vibrancy in the North. If somebody really wants to explore India, then I would suggest getting down to Goa, specifically, South Goa, meeting with the hippie crowd, and getting one of the hippie guidebooks to India. Most people forget that the Hippies came to India in the 1960s and many of them just never left. Tap water in Pune is ok, have seen and experienced the same in Himachal, Garwhal, and Uttarakhand, although it has been a few years since I have been to those places. North-East is a place I have yet to venture into.

      • Old VCRConfirmed! the MOS 7600/7601 Pong chip is a true microcontroller

        The question at the time was whether the 7600 actually had ROM in it (i.e., was a true microcontroller running a stored program), or whether it was simply playing games using discrete circuitry. The Telstar Arcade — and its relative, the confusingly named Telstar Gemini, not to be confused with the separate Coleco Gemini — demonstrated that other variants of the 7600 were capable of more sophisticated games than just ball-and-bat Pong variations, including primitive versions of pinball and road racing, even though most systems using the 7600 used it purely for Pong. On the other hand, no data sheets have survived to the present day and at the time my Google-fu uncovered no die photos to review, so I could find no substantiation for the occasional claims that it did.

      • uni TorontoThe C free() API gives libraries and functions useful freedom

        The third use is what some people proposed as the solution to how malloc() and free() affect C APIs in the case of gethostbyname(). Although a 'struct hostent' contains pointers to various other things, you can pack all of those things together into a single memory allocation that has the 'struct hostent' at the start (effectively you allocate a little arena and then manually manage it). Because this is a single memory allocation, you can return a single pointer to it and the caller can still free everything with a single call to free(). I'm not convinced that this is a good API, but it's certainly one that free()'s API makes possible.

      • uni TorontoC's malloc() and free() APIs are reasonable APIs for C

        I've written about how the free() API means that C memory allocation needs to save some metadata, and before that about the effects of malloc() and free() on C APIs. However, despite these issues I think that C's malloc() and free() APIs are reasonable ones for C to have, and probably that they've helped C remain relevant over the years.

        To start with, both malloc() and free() have what I could call a minimal API, where they take only the arguments that are really needed; in the case of both, this is one argument each. You can't allocate memory without saying how much in some way, and you can't free memory without saying what to free, so it's hard to get a smaller API without some form of automatic handling of memory (including Rust's automatic lifetime management). Having memory allocation as an explicit API has also meant that you can readily write C code that doesn't allocate memory (except on the stack), or use entirely different allocation functions that you built yourself. Both OS kernels and embedded code tend to use something completely different from malloc() and free().

      • Andre Franca[Older/repost] Migrating my Jekyll website to Codeberg Pages

        I've been really busy these days and haven't made any posts. Despite having plenty of drafts for the blog, I couldn't find time to sit down and write.

        Fortunately, unlike any algorithm-based platform, this blog allows me to write at my own pace and as I wish. After all, there's no financial support or, with all respect, any kind of obligations to readers. The dynamics of this blog is quite simple: I write what I want and like, while people who are interested in what I have to say, read it, and when they want, they interact with me by email or on fediverse. And this has been working very well.

        Okay, back to the point that I've been 26 days without posting. I believe that one of the reasons that makes me post less - besides the time factor - it's my publishing workflow. This blog is powered by Jekyll, where I write everything in a .md file, then I push the modifications to my git repository. If I want to add some picture, this process becomes even annoying, as I convert the image to lightweight and web-friendly format, strip the metadata, and upload it to my s3 storage.

So I interviewed 6 Bazel experts and asked them what they like about Bazel, when they would use it, and what to expect or consider before doing a Bazel migration.

          I remember when TensorFlow was released in 2015. Kubernetes was released around the same time (part of Google's reasoning for open-sourcing both was to not make the same mistakes they did with Hadoop/Map Reduce – see Diseconomies of Scale at Google). It was a time when many of the deep learning models (Inception, ResNet, other CNNs, and DNNs) were built with TensorFlow, and the industry rallied around the framework. Facebook released PyTorch a year later.

    • Eagle's Path: Effective altruism and the control trap (2022-09-17)

      William MacAskill has been on a book tour for What We Owe to the Future, which has put effective altruism back in the news. That plus the decision by GiveWell to remove GiveDirectly from their top charity list got me thinking about charity again. I think effective altruism, by embracing long-termism, is falling into an ethical trap, and I'm going to start heavily discounting their recommendations for donations.

      [...]

      I think one can sometimes do better than transferring money, but doing so requires a deep understanding of the infrastructure and economies of scale that are being used as leverage. The more distant one is from a society, the more dubious I think one should be of one's ability to evaluate that, and the more wary one should be of retaining any control over how resources are used.

      Therefore, I'm pulling my recurring donation to GiveWell. Half of it is going to go to GiveDirectly, because I think it is an effective way of redistributing wealth while giving up control. The other half is going to my local foodbank, because they have a straightforward analysis of how they can take advantage of economy of scale, and because I have more tools available (such as local news) to understand what problem they're solving and if they're doing so effectively.

      I don't know that those are the best choices. There are a lot of good ones. But I do feel strongly that the best charity comes from embracing the idea that I do not have special wisdom, other people know more about what they need than I do, and deploying my ego and logic from the comfort of my home is not helpful. Find someone who needs something you have an excess of. Give it to them. Treat them as equals. Don't retain control. You won't go far wrong.

    • Gregory HammondHow feedback helps you become a better speaker - Gregory Hammond

      Every talk you give can help you become better. You’ll most likely just hear positive feedback, because it’s let’s face it, it’s a bit weird to hear strangers give negative feedback when they’ve only hear you speak once.

      It is better to just get positive feedback or to get positive and negative? It all depends on speaking experience and what sort of feedback is wanted. Meaningful feedback that includes details I find is always wanted so that the speaker knows exactly what they did well on and what needs work.

      Should a speaker give themselves feedback? Yes, because then you can know what you covered in your time, what you felt needed work and what you did well on. Once you have that written down you can stop thinking about your own feedback and start reflecting on all the feedback given.

        First things first, what are metamaterials? A linguistic approach might lead you to think a metamaterial is what comes after the material, so I guess, that’d be the bill. But that’s not quite right. A metamaterial has custom-designed micro-structures which give a material new properties. These micro-structures are typically arrays that resonate at specific frequencies, and that interact either with acoustic waves or with electromagnetic waves. This way, metamaterials can be used to control sound, heat, light, and even earthquakes.

This should be so obviously dangerous as to be unnecessary, but it’s become widespread enough that the US Consumer Product Safety Commission has issued a warning about the practice. In particular, they’re concerned that there’s not even a need to wire up a lead, as they’re readily available on Amazon.

          I promised a travelogue, and here we go. I'm not exactly a travel writer, but I was recently able to visit a place that's fairly difficult to get to, so I think it's worth sharing my observations. I started writing this because I thought there should be more on the internet about the NNSS tour program and the site and tour as a subjective experience. Personally I absolutely love tours, not just to see things but because I think the tour guide and the design of the tour are often just as interesting as the site itself. When you take a guided tour you are sort of seeing a place through the eyes of its own public affairs department, and when it comes to the national security state that is an especially interesting thing to behold.

        • Computers Are Badthe nevada national security site pt 2

          After our time milling around the Mercury cafeteria, it was back aboard the coach to enter the test site proper. As our guide explained, the NNSS can be divided into work areas such as Mercury and the range itself. On the days that tests were scheduled, everyone other than personnel for that specific test was prohibited from entering the range area for safety reasons. Considering weather delays and technical issues, this sometimes meant a full day of lost work as the entire staff huddled in Mercury awaiting news that they could once again head out to test sites.

        • Computers Are Badthe nevada national security site pt 3

          I said up front that the NNSS remains in use for several different purposes, although the level of activity today is not nearly as high as it once was. To my best ability to remember the numbers, I think we were told that during the period of active testing the staff compliment was about 13,000. Today there are about 8,000 personnel that work at the site, between the various contractors and subcontractors. This is as good a time as any to elaborate a bit on the organizational structure of the NNSS.

        Furthermore, the bill grants “any employee or applicant for employment adversely affected or aggrieved by a final order or decision of the Merit Systems Protection Board may obtain judicial review of the order or decision.”Research by the Government Accountability Project (GAP) showed [PDF] in the first six months of 2021 that MSPB judges “ruled against whistleblowers in fifty of the past fifty-one retaliation cases.” “Federal employees are the only major labor group of whistleblowers in the country who don’t have access to a jury trial to challenge retaliation against their free speech rights,” GAP legal director Tom Devine declared. “Instead of being able to seek justice from a jury of the citizens who they are reporting to defend when they risk their careers, their day in court is limited to administrative judges who rule against whistleblowers in 96 percent of cases and are extremely vulnerable to political pressure.”Devine also said, “It is ironic and indefensible that federal employees, whose whistleblower disclosures are the highest stakes for our country, have the weakest due process rights to defend themselves.”Significantly, the bill recognizes the impotency of the MSPB by making whistleblower access to a jury trial “retroactive for claims filed to MSPB for up to five years prior to the date of enactment.” This means whistleblower complaints from as early as the first year of Donald Trump’s presidency, which are still pending before the MSPB, could be submitted to a federal court.

      • [Old] The State of MichiganBackground Information on Lake Levels in the Great Lakes

        Great Lakes waters are composed of numerous aquifers (groundwater) that have filled with water over the centuries, waters that flow in the tributaries of the Great Lakes, and waters that fill the lakes themselves. Although the total volume in the lakes is vast, on average less than 1 percent of the waters of the Great Lakes is renewed annually by precipitation, surface water runoff, and inflow from groundwater sources.

      • [Old] Why the water in the Great Lakes should not be "for sale", according to one Michigan author

        In the drought-stricken West, some people are turning toward the Great Lakes and asking, what if we could bring some of that water out here? It wouldn’t be the first time water’s been diverted from the Lakes. Would-be buyers might also point to commercial water bottling in Michigan, says conservationist and Western Michigan University graduate Dave Dempsey.

      • Michigan’s groundwater and the public trust doctrine

        Nestlé’s extraction and sale of Michigan groundwater have been consistently challenged by water conservation advocates. The Great Lakes Compact, a legally binding interstate compact between the Great Lakes states, bans the removal of water from the Great Lakes basin.12 But there is an exception: water may be transported elsewhere if it is in containers of 5.7 gallons or less, although states may pass more restrictive laws.13 Some have called this provision a loophole; others have argued that the water extracted is not nearly enough to affect Great Lakes water levels. Whatever one’s assessment of this exception, it means that the compact does not prevent Nestlé (or anyone else) from bottling groundwater from the Great Lakes basin and selling it elsewhere.

        CURRENT BILLS

        Michigan lawmakers in March introduced a package of three bills intended to protect the state’s groundwater resources. Similar bills have been introduced in past sessions without success. Rep. Yousef Rabhi (D-Ann Arbor) introduced 2022 HB 5953, which declares that “[t]he waters of this state, including groundwater, are held in the public trust by this state. The public trust in the water of this state applies to the quantity and quality of the water.” Rep. Rachel Hood (D-Grand Rapids) introduced 2022 HB 5954, which would remove the exception permitting withdrawal of water from the Great Lakes basin in containers smaller than 5.7 gallons. And Rep. Laurie Pohutsky (D-Livonia) introduced 2022 HB 5955, which would add the “protection [and] conservation of…water” to the Michigan Natural Resource Commission’s mandate.

        All three bills were referred to the House Committee on Natural Resources and Outdoor Recreation, where they remain as of this writing. No hearings have been scheduled.

      • Relative Power



        We know intellectually that power is relative, but I never clearly feel that in the moment. When I exercised and gained muscle, I didn't feel like I rejoiced in a world which had - relatively speaking - lost leg-muscle. But then again I don't see the functional difference. If everyone gains muscle power, we would become weaker by comparison, and what could be more practical than seeing the world in terms of relative values? If everyone in the world doubled their bank accounts and earnings, nothing would change.

        But then the opposite approach doesn't make any sense. If I lose muscle, the world does not need to celebrate that they - relatively speaking - have become stronger.

        [...]

        Maybe the Zen school of thought has is right, and we should just focus on whatever happens, without care for comparison or celebration.

They can be used for cooking, eating, cutting paper, or pealing fruit. They can also be used for stabbing, cutting up, killing, and skinning people and animals. That doesn't make them undesirable or less appealing in any way. It's not why/how most would use them, and I wonder how we'd go about our lives without knives!

          Earlier this week, the €«€ Collective Directory of Geminispace€ €» was announced[1]. In short, it is a capsule listing links to other capsule in a categorized manner. This could be a very common thing, but the particularity here relies on being community driven.

          A bit like with Antenna[2], geminauts push the information to CDG, adding themselves links they find interesting. I liked the idea a lot and wrote on my tinylog the day of the announcement as well as posting the link in geddit[3]. I started this post as an email I to share a quick feedback about CDG, but thought it might as well be a public response. If it helps even 1 person discover this capsule then it would be worth it instead of a private email.

        • Considering using IPFS for content hosting

          I like the concept of IPFS. I'm considering using it to host my homepage and possibly my Gemini capsule, and to pin some resources pertaining to FOSS, mental health, and digital rights. I'm just not sure about its adjacency to the NFT/Web3 scene.

          In theory, I would setup an IPFS node on my Digital Ocean VPS, and use DNSLink to link my domain to an IPFS content address that points to the latest version of my homepage. The IPFS node would also contain pinned web resources that I'd like to keep available through IPFS.

          One could use IPFS for its decentralization aand p2p features without ever using Protocol Lab's Filecoin-based NFT and Web3 storage. At least Filecoin uses proof-of-storage cryptocurrency algorithms that are greener and fairer than the computation-based proof-of-work algorithm of Bitcoin, so that kind of eases my conscience a bit.

          In the video lecture, recorded two years ago, he said the maze needed to be 100x100. I didn't want to create a 100x100 2D array of 0s and 1s, building the maze, manually. I thought it'd be easier to write a script to convert a black and white image into the maze so I could draw it in gimp. I saw a video by "Films by Kris" that showed off the "convert" command from ImageMagick which allows you to convert an image to text. This is easier to parse since my graphics knowledge is limited.
