I use a Huawei Matebook X as my primary OpenBSD laptop and one aspect of its hardware support has always been lacking: audio never played out of the right-side speaker. The speaker did actually work, but only in Windows and only after the Realtek Dolby Atmos audio driver from Huawei was installed. Under OpenBSD and Linux, and even Windows with the default Intel sound driver, audio only ever played out of the left speaker.
Now, after some extensive reverse engineering and debugging with the help of VFIO on Linux, I finally have audio playing out of both speakers on OpenBSD.
For some reason I like small laptops and the constraints they place on me (as long as they're still usable). I used a Dell Mini 9 for a long time back in the netbook days and was recently using an 11" MacBook Air as my primary development machine for many years. Recently Microsoft announced a smaller, cheaper version of its Surface tablets called Surface Go which piqued my interest.
In the past couple weeks I contributed to a bunch of different open source projects in different ways and I thought I'd write about some of them.
I switched from Dropbox to Syncthing a while ago and so far it's been pretty great. I run it on my macOS server in the basement which mirrors everything on its large disks, and also on my various laptops where I selectively sync certain directories that I need.
Seven years ago, I hacked together some code to update my Ecobee WiFi thermostat temperature depending on whether I was home. While my newer Ecobee thermostat has room occupancy sensors that make this tracking automatic, back then I had to poll my WiFi access point through SNMP to look for my phone's MAC address in its table of associated clients.
Recently I needed to do something similar to pass to my Z-Wave controller but it seems that Apple has removed SNMP support from its Airport Extreme firmware some time ago.
The Dolch PAC 64 is a portable, rugged Pentium-powered PC from the mid 1990s. It was usually used (and can usually be found on eBay) as a "portable network sniffer" complete with multiple network cards supporting multiple media types.
I've been using an OpenBSD laptop as my workstation a lot more lately, probably because most of my hardware just works now and I don't have to think too much about it. The touchpad works when I touch it, I can be confident that when I close the lid, the laptop will fully suspend and then fully resume again when I open it, WiFi works all throughout my house (although it's not terribly fast), and my web browser is fast and stable. What amazing times we live in.
In the past, one thing that frequently kept me going back to my Mac, aside from iOS and Android development, was 1Password. I have a ton of logins for websites and servers, and because my browsers are all configured to clear cookies for most websites after I close their tabs, I need frequent access to passwords synced across my laptops and phones, and 1Password has great apps for all of those except OpenBSD.
ThinkPads have sort of a cult following among OpenBSD developers and users because the hardware is basic and well supported, and the keyboards are great to type on. While no stranger to ThinkPads myself, most of my OpenBSD laptops in recent years have been from various vendors with brand new hardware components that OpenBSD does not yet support. As satisfying as it is to write new kernel drivers or extend existing ones to make that hardware work, it usually leaves me with a laptop that doesn't work very well for a period of months.
After exhausting efforts trying to debug the I2C touchpad interrupts on the Huawei MateBook X (and other 100-Series Intel chipset laptops), I decided to take a break and use something with better OpenBSD support out of the box: the fifth generation Lenovo ThinkPad X1 Carbon.
The Huawei MateBook X is a high-quality 13" ultra-thin laptop with a fanless Core i5 processor. It is obviously biting the design of the Apple 12" MacBook, but it does have some notable improvements such as a slightly larger screen, a more usable keyboard with adequate key travel, and 2 USB-C ports.
It also uses more standard PC components than the MacBook, such as a PS/2-connected keyboard, Intel WiFi card, etc., so its OpenBSD compatibility is quite good.
For the majority of the past five years, Pushover has run on one physical OpenBSD server. It does have a hot spare hosted with another company in another part of the country, but usually everything has been served from just one machine at a time. Its MariaDB database is replicated in a master-master configuration over a secure tunnel between the servers so that either node can become active at any time.
Back in 2015, I created a BBS for Lobsters that worked in a web browser via WebSockets. After getting an old Mac earlier this year, I wanted a way to access the BBS from the Mac as natively as I could. Adding telnet and SSH frontends to the BBS was not too difficult, but being able to login from my Mac took a bit of work.
The Xiaomi Mi Air 12.5" is a basic fanless 12.5" Ultrabook with good build quality and decent hardware specs, especially for the money; while it can usually be had for about $600, I purchased mine for $489 shipped to the US during a sale.
Note that the current models being sold have a 7th generation (Kaby Lake) processor, so OpenBSD compatibility will be different.
I recently had access to a Surface Pro 4 and tried to boot OpenBSD on it. It did not go well, so I am just putting this here for posterity.
The 2016 Surface Pro 4 is basically just a keyboard-less x86 (Core i5 on the model I had) tablet with some tightly integrated (read: not upgradeable) components. Its optional Surface Type Cover is just a USB-attached keyboard and trackpad, which magnetically secure to the bottom of the device.
I've been using an 11" MacBook Air as my primary computer for six years. It's a great computer that satisfied a lot of requirements I had for a laptop: thin, lightweight, small form factor, excellent keyboard and touchpad, mostly silent, but not an Atom or Core M processor.
I've done a lot on this little computer, like compiling and maintaining an Android ROM, writing the Rails, iOS, and Android apps for Pushover, creating Lobsters, recording and editing 40 episodes of Garbage, and lots of OpenBSD development.
The Chromebook Pixel LS (2015) has an Intel Core i7 processor (Broadwell) at 2.4Ghz, 16Gb of RAM, a 2560x1700 400-nit IPS screen (239ppi), and Intel 802.11ac wireless. It has a Kingston 64Gib flash chip, of which about 54Gib can be used by OpenBSD when dual-booting with a 1Gb Chrome OS partition.
Although it fooled nobody, yesterday for April Fools' Day, Lobsters users that normally saw a boring list of story titles and links were greeted with a BBS-style interface to the site complete with story and comment browsing, private message reading and sending, and a multi-user chat area.
