It's released!

An SA.22c with manual DDS tuning referenced against an X72 firmware disciplined to a ZED-F9T L1/L2, 101 minute run.

The Monoprice S/PDIF TOSLINK to RCA coax adapter is a handy device, but its output is pretty hot -- my oscilliscope reads a bit more than 1V pp into 75Ω termination, about twice what the specification describes.

Say hi!

A gentle update to the 2021 documentation. $ export QEMU_INSTALL=/path/to/qemu/install $ brew install pkg-config pixman pcre $ python3 -m venv qemu_install_venv $ source qemu_install_venv/bin/activate (qemu_install_venv) $ pip install --upgrade pip setupt…

Recently I had an immediate need for hardwired network connectivity on my M1 Air, and could only secure a QinHeng CH9200 dongle that doesn't have macOS drivers.

Checkout https://github.com/sm64-port/sm64-port.git, apply the following super hacky diff, brew install gcc mingw-w64 make pkg-config sdl2 glew libusb, copy the ROM per the docs, and run gmake (for the newer brew version, not the old OS one). $ file build…

It's released!

This will give per-currency totals.

It's released!

I had all manners of issues that I couldn't figure out after trawling through Console.app logs: 3+ seconds of latency between hitting a play button and hearing audio Beach-balling when opening Zoom preferences Latency between pressing volume up/down keys…

Not sure if this change is a Citrix or Mac thing.

brew install qemu unnecessarily brings in Python, a DNS server, two TLS libraries, ....

Microsoft distributes a freely available image, but there are a few steps necessary for it to work with QEMU.

This seems to happen to me every time I twiddle time zone settings when traveling. iStat Menus (in my case; or similar) says the Intel GPU pushes 50 frames per second though the display is static Nothing particularly notable in Console.app.

NB: this is out of date.

It's released!

# systemctl mask getty-static.service # systemctl mask getty@tty1.service # systemctl mask serial-getty@hvc0.service

Probably works on older versions, too.

nginx doesn't (yet) support configuring TLSv1.3 ciphersuite order preference.

Follow the installation instructions on the WireGuard website.

xhyve is a nice and lightweight hypervisor for macOS.

It's entirely undocumented, for good reason.

It's disabled by default, and if you add e.g. tls-cipher TLS-DHE-RSA-WITH-AES-256-GCM-SHA384 (a TLS v1.2 cipher) to your server config it silently breaks.

For certain international sports, the two most popular kinds of streams I've come across are Sopcast and Ustream.

This uses the newer 6rd mechanism instead of the 6in4 tunnels, so other documentation you enounter may inapplicable.

Pass these options on the kernel command line: auto=true priority=critical url=http://your.server/foo.seed, and use this preseed file: d-i debian-installer/locale string en_US.UTF-8 d-i passwd/root-login boolean true d-i passwd/make-user boolean false d-i

Yeah, someone really dropped the ball here.

Capistrano scares the shit out of me.

I came across an interesting video on the web that I wanted to watch offline, but it played through a Flash application, there were no download links, grabbing the stream by looking through the HTML/DOM was nontrivial, and the youtube-dl mainstay didn't w…

First, install the Heirloom mailx client with yum install mailx.

Yep, I had a reason to break out my old MBP and install the newest version of OS X on it.

...well, except for the cipher suites that require an OpenSSL >= 1.0.0, but that's an adventure for another day. wget http://redmine.lighttpd.net/attachments/download/1395/ssl-compression.diff wget http://ftp.us.debian.org/debian/pool/main/l/lighttpd/ligh…

Use WikiTaxi through Wine.

Unable to start nfsd or portmap in Debian?

It's released!

In preparation for a pending semi-major release of unpkg, I needed to compile some source for other architectures and older versions of Mac OS X on my Snow Leopard MacBook Pro.

Problem: you acquire a MKV file you want to play on your iPad.

Sometimes, at work, we have terrible internet latency.

Like many programmers, I was introduced to the craft through a BASIC dialect, specifically a MacOS-only one named METAL.

I can't vouch for the Extra Large or Double Extra Large ones, but the Quadruple Extra Large ones use Nehalem-based Gainestown Intel Xeon X5550 @ 2.67GHz. processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 26 model name

Build as listed on the website.

Just modprobe snd_pcm_oss and snd_mixer_oss, and restart udev.

You'll want to use something called the Compose Key.

On my Debian boxes I use evilwm as my window manager, because it gets out of my way in just the way I like.

Certain build scripts require Python 2.6, so find some way to install it (Debian experimental, by source, etc.) apt-get install libqt4-dev qt4-qmake netpbm gforth build-essential php5-cli sqlite3 git clone git://github.com/wikireader/wikireader.git cd wik…

I've tested SheepShaver with Mac OS 7.6.1 and Mac OS 8.1 with a 4MB OldWorld ROM.

Just contributing my method.
