The official Go docs say the term rune was introduced for conciseness, but there’s more to it. We dig into the thirty year intertwined history of UTF-8 and “rune,” and hear directly from Rob Pike on the origin.

Neat idea! I’d love to use my current RSS feed reader (NetNewsWire) to follow links that come across my Mastodon feed. I can already follow individual accounts or tags with the .rss pages Mastodon generates.

It should be possible to create a service that produces personalized RSS feeds, something like: https://codeberg.org/gedankenstuecke/mastolink2rss

It's over-engineered, but I wanted to try running k8s in my homelab to continue learning about networking; deploying a blog seemed like a perfect test case. The cluster uses Traefik, https://github.com/travisghansen/kubernetes-pfsense-controll... to sync service definitions to HAProxy, and MetalLB. The k8s service IPs are routable from my local network, as well as the MetalLB IPs, and MetalLB handles syncing them to pfSense using BGP. pfSense sends DNS for any *.k8s.home.arpa to k8s, so I can resolve e.g. blog.default.svc.k8s.home.arpa on my local network.

One interesting hiccup: I had to introduce a NAT at pfSense because MacBooks don't listen to ICMP redirects, the packet would go laptop -> router -> k8s and then k8s -> laptop. Since the MacBook ignored the ICMP redirect, it drops the reply packet.

Thanks! I’ll update this shortly

I run it out of my closet. The blog is a small Go program deployed to a k8s cluster across a few ESXi VMs on an HP DL380 G7, behind a pfSense router also running as a VM and using HAProxy for TLS offloading. My connection is 1gbps symmetric.

With no cache on my local network, Chrome reports the page loads fully in ~500ms, using the "slow 3G connection" performance tab preset it takes ~4s.

If you're nowhere near Little Rock, Arkansas; that might be the issue. I don't yet use a CDN and it always loads the same resolution image ("high" quality JPEG, ~200kb apiece).

Thanks for the advice. I found a copy of NCSA Mosaic 1.0.3 and it works on the Macintosh SE running System 7! The next version, Mosaic 2.0.1, needs 5MB of free memory. Mosaic does a better job handling larger pages like this blog post, and even chews through the inline SVG diagrams and renders just the text.

My only complaint is that Mosaic uses the serif default font we're all used to, instead of the sans-serif default used by MacWeb, which makes it a little harder to read at such a low resolution.

Added a section on it to the bottom of the article :)

Using an Apple MIDI Interface to record an Ensoniq ESQ-1 on a Macintosh SE using Cubase 1.0

This post took a while to write, and has been continuously updated since early this month. It covers my experience connecting a Macintosh SE from 1987 to the Internet, printing from a modern iPhone to a dot matrix printer from 1985, setting up AppleShare from a Linux computer, and some networking history.

This post took a while to write, and has been continuously updated since early this month. It covers connecting a Macintosh SE from 1987 to the Internet, printing from a modern iPhone to a dot matrix printer from 1985, how to set up AppleShare from a Linux computer, and some networking history.

If the printer supports IPP advertised via Bonjour (mDNS), with PDLs including PDF, then I think all that's missing is the Apple Raster (image/urf) PDL on the mDNS entry and the URF entry. The image/urf support doesn't have to be real, since it's proprietary CUPS on Linux won't support it but I haven't run into an issues yet, I think iOS uses it mostly as a marker and otherwise respects the pdl ordering. You might look at the Discovery app to see what the mDNS records its currently advertising are. The URF entry can encode a bunch of information (info here: https://wiki.debian.org/CUPSAirPrint), but I've gotten away with URF=DM3.

I believe many Bonjour printers are of the kind that you can create by plugging a USB printer into an Airport, and they require a driver on the client. Apple makes this pretty simple by automatically searching for the driver based on the usb_MFG and usb_MDL from the printer's IEEE 1284 Device ID. None of these drivers would work on iOS, given its a different OS on a different architecture. I think AirPrint was the first driverless printing standard, followed by the PWG standard, and since they used existing technologies I assume they wanted iPhone users to only see printers which would actually work.

Bonjour also supports PostScript printers, which would use a PPD file on the client to configure the UI options and generate a PostScript preamble (this also requires generating a PostScript file from a PDF on the client -- a somewhat expensive operation). I don't know much about this apart from the couple of times its mentioned in the spec: http://devimages.apple.com/opensource/BonjourPrinting.pdf.

The practical solution is to have your friend configure a print server and advertise AirPrint mDNS on their network -- besides printing from my own iPhone, having friends be able to print to my decades-old but mighty HP LaserJet just by hopping on WiFi has been great.

This is cool! Blurring the line between what is and isn't part of the printer itself

Yes, no drinkware was harmed in the creation of this blog post

I don’t think such a method exists. Modern printers do usually support driverless printing out of the box, but for older printers that still work well, there was no IPP Everywhere or AirPrint standard when they were manufactured, and there are no new firmware updates. Using another system to translate from these protocols and modern formats like PDF is required

I started a new blog and though writing about using twenty-year-old printers from your iPhone would be a good early post

What’s the transfer speed, are there practical file size limits? Do you have to wait for it to loop or can the reader pick up in the middle of the stream?

The reference implementation of CommonMark, cmark (https://github.com/commonmark/cmark)

cmark can render a Markdown version of War and Peace in the blink of an eye (127 milliseconds on a ten year old laptop, vs. 100-400 milliseconds for an eye blink). In our benchmarks, cmark is 10,000 times faster than the original Markdown.pl, and on par with the very fastest available Markdown processors.

I also don't think his quams about performance apply to commonmark. It benchmarks quite fast

I think this is total BS. All the example pages seemed plenty navigable to me.

I personally don't like the ugly monochrome bar across the top. (Although I do like it when one appears as I scroll down the page, fading in)

#define mycalloc(N) calloc(1, N)

I am not a fan of the use of macros here. You should never use macros.

Instead maybe: static inline void *mycalloc(size_t sz) { return calloc(1, sz); }

First off, Tor is not the Tor Browser. Tor is the onion network through which the Tor Browser (and any other client, for that matter) connect through.

When should normal users not use Tor?

Since Tor has drawbacks such as speed, it may prove impossible or at least difficult to use Tor all the time. If you really want the extra anonymity, go for it. Personally, I don't care if Google keeps a tally of all my searches and piles cookies on me, I enjoy personalized search results. Anonymity is useful sometimes though. You could definitely use it 100% of the time though.

Should it always be used with a VPN?

Tor provides an onion network, I don't see a need to ever use a VPN.

Should normal users use a different browser when accessing personal accounts (banks, email, shopping)?

The Tor Browser doesn't keep cookies and other identifying information, so it's as if you're using a fresh browser each time you access these services. Security-wise, SSL will encrypt banks and email (most likely). So accessing those services in a normal browser doesn't inherently put your privacy at risk.

What are the problems with using Tor as my only browser?

Speed issues, as the network is pretty slow at times. Otherwise I can't think of anything really.

NOTE: I'm not an expert on Tor, I'm just speaking from personal experience.
