    1. Whatever happened with UMN vs. Linux Kernel Maintainers?

      Even tech news moves a bit too fast for me to keep up. Did UMN ever get unbanned? I saw a half-hearted apology and then finally this [1], but never heard any update. Most recent article I've seen is this ZDNet article [2] from a couple of weeks ago discussing a related issue, but still mentions that UMN is still banned.

      Anyone following this?

      Welcome back!

      Right after making this post, I'm going to update the DNS records to point tildes.net to this server, so everyone should start trickling in as those updates go through.

      The switch and upgrades all seem to have gone fairly well, though there were definitely a few issues here and there that I had to work through. I'm glad I decided to do a longer downtime instead of needing to rush through figuring some of it out.

      A summary of what's changed so far:

      • Running on a different physical server (but in the same datacenter)
      • Operating system is now Debian 10 instead of Ubuntu 16.04
      • Python version is now 3.9 instead of 3.8 (and updated a couple libraries that needed it)
      • PostgreSQL version is now 13 instead of 12
      • Redis version is now 6 instead of 5
      • Everything was deployed and configured using Ansible instead of SaltStack

      There are still a few more changes and updates I want to make soon, but I can just do them normally while the site is running. I'll also update the open-source code soon, once I finalize a few pieces and finish cleaning things up.

      Please let me know if you notice anything that seems to be behaving strangely, it's definitely possible that there are some things broken in subtle (or not-subtle) ways.

    4. Tildes will be down for most of this weekend

      I'm going to be taking the site down this weekend to do some upgrades and changes to various systems it runs on. I'm planning to start the downtime somewhere around noon on Saturday, and have it running again on Sunday evening (vague times, in a vague North American timezone).

      If you're interested in the details, the main reason is to switch operating systems from Ubuntu to Debian. The easiest and safest way to do this is by just setting up a new server and moving the site over, so I'll also be taking the opportunity to switch to a different physical server. Tildes has been running for 3 years now, so I'll be able to rent a new server that's some combination of faster and cheaper (not that we're getting anywhere close to the limits on this server, but I might as well).

      Since I was having to review and adjust the whole server setup as part of switching OSes, I also decided to switch configuration-management systems from SaltStack to Ansible. Salt had a major vulnerability last year that compromised thousands of servers, and Tildes really only avoided being affected through the luck of using it in a non-vulnerable way. I've been intending to switch away from it ever since.

      And since the site will be down anyway, I'll also be doing some upgrades and changes that are difficult to do without downtime, including upgrading PostgreSQL, Redis, and Python to their newest versions and making some changes to their setups.

      So overall, this turned into a large project, and unfortunately it's one of those wonderful development projects where you do a ton of work and if everything goes well, nobody can even notice any difference from the way it was before. It also would have been possible to do all of this with only minimal downtime, but it would have required a lot more prep work and would be more stressful, so I'm just going to do it the easy way and take my time. If you're interested in doing a Screenless Day, maybe this could be a good time to do it!

      I am not a developer, but I do have interesting in learning.

      A while ago I asked a question similar to that. I did not take any concrete action since then, and now have some new information to add.

      The website shall be called myactualname.com, and will contain about/biography, and a few sections containing articles that I wish to write on different subjects.

      That can probably be done without coding on one of the many free blogging platforms currently available, such as Medium, Wordpress, and Substack, but the lack of control is unfortunate.

      At the same time, I wish for this website to last a long time, and to be reasonably independent of maintenance. With the Brazilian Real valued at less than one-fifth of the US dollar, hosting prices skyrocketed. Besides, I cannot always rely on my own ability to stay on top of that kind of thing, so it would be beneficial for my web presence to be more resilient than my bank account and mental state. I figure that hosting it on Github Pages, Gitlab Pages (or both) would be a good way to avoid ever going down (it looks like duplicate content is bad for search engines, though, so I might keep one of those private, just for backup reasons). And I could reserve the domain for two or three years in advance.


      I really like simple text-focused personal websites like this one. They load fast and are easy to read, but are generally not very pretty or responsive. I have basic notions of HTML and CSS and intend to learn more.

      In the previous post, someone suggested using Hugo, which seems like a good option. On the other hand, for something that simple, I wonder what would be the downside of simply coding it from scratch. One thing I know for sure is that I want this website to be rather permanent: whatever changes I ever do to its design should not impact accessibility to previous content (link rot). How can I achieve that? No idea.

      Since I write in English and Portuguese, the website must be bilingual. I'm not sure how to implement or manage that, especially in regards to search engines.

      I resumed the course on Free Code Camp, which I expect will help in achieving all that.


      With that in mind, I reiterate my question: should I make my personal website? Should I just use a free blogging platform? Should I use Hugo or something similar? Any particular free CMS? Or maybe just use what I learn to code it from scratch?

      Thanks!

    6. (Option to) mark comment reply notifications as read when clicking "link" or "parent"

      When I get comment reply notifications, I normally prefer to read them in context of my own reply, and potentially other replies. However when I do this, the notification doesn't go away on its own, so I have to return to the page to click "mark as read".

      I know I can also mark the notification as read by voting on or replying to the reply, but I often don't do that. Yet I always seem to want to view the comment in its context, which requires me to leave the notifications page. In this specific use case there is no convenient way to mark the notification as read without going back.

      To avoid the extra page load, I would like the notification being marked as read when the link to it is opened, to be an option. (Actually, I'd like it to be the default behaviour, but since the current default behaviour is to not mark comments as read until an explicit action is taken on them, I suppose I'm in the minority. An option is just fine.)

      In a discussion on Hacker News, Jonathan Mayer pointed out that the differential privacy code was removed from Chromium. It looks like they finished doing this in February.

      I haven't seen any announcement, discussion, or explanation of this based on a brief web search, so I figured I'd note it here.

      At about the time this process finished, there was a Google blog post about how they're still using it in other products.

      We first deployed our world-class differential privacy anonymization technology in Chrome nearly seven years ago and are continually expanding its use across our products including Google Maps and the Assistant.

      (If you read this quickly, you might think it's still used in Chrome.)

      Reading between the lines, I suspect that some folks at Google are still advocating for more usage of differential privacy, but they lost an important customer. Why that happened is a mystery.

      Has the sentence "the masked men entered the store" changed meaning post the pandemic. I think it feels less ominous than perhaps it used to. Now the words could imply "responsible men that wear masks in accordance with guidelines entered a store" where it would previously almost certainly imply "robbers entered the store". Since I'm not a native speaker I'm curious if this is just in my head or a more general thing? Are there other similar statements that has change?

    14. Project: Miniature longsword

      Over the last couple of years my sister has been getting into HEMA (Historical European Martial Arts) and especially the longsword. She recently had a significant birthday so I thought I'd make her a small, but realistic and functional, longsword. It went pretty well, if I do say so myself. I did not, however, take as many photos as I would have liked, but I was doing this thing in very short bursts so I only had a few minutes here or there to get this done.

      To start, I read a bit about longsword proportions, looked at some pictures and sketched a couple of possible designs, before finalising a 1:1 scale drawing to work from. I bought some O1 tool steel (carbon steel so it can be hardened and sharpened properly) and started to cut. Almost immediately I made a mistake, I cut the steel 25% too long. But that was OK, I just went with it.

      I roughly shaped the metal and got it in the forge to heat-treat. Plunged into oil then slammed hard into my newly-built plate quench (aside: the plate quench is two hefty slabs of aluminium, designed to suck heat out of the steel fast, while holding it flat to prevent warping). The plates worked, the metal came out dead flat and not at all warped, which was good because there was very little space to grind out any distortions. I heart plate quenching.

      Next, cutting up some brass to make the crossguard. Cutting a 1.5x3mm slot in that was incredibly frustrating. I broke all four of my remaining 1mm drill bits, eventually had to resort to very fine diamond burrs and going extremely slowly. Luckily there is a bit of overlap from the blade so the slightly messy slot is covered up a bit. Similarly for the pommel, which was cut from brass rod and shaped on my lathe before I totally botched cutting a hole for the tang. If anything I made more of mess of the pommel, during the final fit up I just filled it with glue and wedged it in the right place.

      Inbetween making an awful - albeit recoverable/hideable - mess of the sword hardware I also finished up shaping and finishing the blade itself. This is where I don't have a lot of photos, but I ground a bevel onto the blade and wondered about cutting a fuller (groove down the centre of the blade) before realising that I absolutely did not have the tools to do that and would make a total mess of it. I also thought about sharpening it to scary sharp but given my sister has two reasonably small children I left it fairly blunt. It'll make a good letter opener but not much more. If she wants it sharp I can always put a serious edge on it another time.

      Final pre-glue fit up, as you can see it matches the design drawing pretty well, apart from being to a slightly different scale.

      I had considered making a wooden handle, as is traditional, but I was running short on time and I had plenty of leather so instead I did two layers of wrapping. This is the base layer (I do not remember why I have 1mm orange leather but I do) wrapped and clamped so the glue can dry. Another layer went on top of that and I ran a final polishing disc over everything, put a very light coat of metal lacquer over the metal to keep it shiny and that was it. Sword done.

      I cut a piece of round bar steel, cut and forged it to shape as a support, treated the hot metal with beeswax (gives a lovely black finish which stops rust and looks nice). I set this in some flame-finished oak and gave that a coat of tung oil. Once the various finishes and glues had dried it was good to go.

      The final product, dangling point, handle detail, view from above and in my hand for scale

      I think this is one of the best things I've ever made. I hope my sister likes it. I have some metal left so I might try making another - there's a few things I'd do differently.

      I just wanted to see what everyone else’s experience has been working with your ISP. I recently had a horrible experience and wanted to see if anyone else can relate and maybe just vent a little.

      My recent experience: I moved to a new town, and I had been experiencing issues with my internet dropping out, as we all probably have had at some point, and I contacted Cox communications through their chat app. After multiple attempts to fix it, they finally sent a tech out to find that the coax connectors at the pole were rusted out. He replaced them but it wasn’t fixed completely. The tech dismissed it and said to just use it for now and I wouldn’t notice. So I did, and it wasn’t great at first, but it actually slowly got better and was good for a while until the last couple of weeks. This past week every single night it would drop out. I watched the connection drop while I was trying to watch mythic quest (great show btw) and every night for the past week the internet was unusable in the evenings. I then contacted Cox again multiple times, got a credit refunded back to my account and they wanted to do the whole reset modem thing again, so I did just to get to the next steps. Again they said use it and see if it improves, so I did, and it didn’t. I contacted them again, and again the modem reset, so I got fed up and filed a complaint with the FCC while I was chatting with this guy and he had the nerve to try and sell me home automation at the end of our chat!

      The next day goes by, a woman from their escalation lines contacts me about my FCC complaint and they send a new tech out. Turns out Cox never buried my original line in conduit, so the line was probably damaged underground as it was sending a weak return signal. The tech ran a new drop from a different tap and used the thickest coax I’ve ever seen. So far it’s been good after the new drop, but it took multiple chats and calls with two different field technicians and an FCC complaint to get it fixed. The worst part about it is Cox Communications is the only broadband ISP in my area other than Starlink and I seriously considered Starlink. So if you read this far, thanks! Please share your experiences if you’d like, or if you want to vent that’s okay.
