polpo··on Apple's list of 235 apps that are incompatible with macOS Catalina
The first public beta of Q3Test was released on MacOS first: https://web.archive.org/web/20000229083216/http://macweek.zd...
polpo··on Understanding the working of X11 from the ground up (2017)
I want to thank you for this page! It really helped me understand how X11 worked when my job at the time required some rather esoteric (to me) X11 knowledge. I had to write a very specific purpose window manager (in JavaScript, which really made it interesting) that had to work around some odd client behavior, and I also had to submit a patch to X.org to fix a bug in Xephyr. Without your guide I would have spent far longer digging in the docs to figure things out.
polpo··on Colorado Town Offers 1 Gbps for $60 After Years of Battling Comcast
The $50/mo rate is for charter members who signed up within the first 3 months of it being available. New customers have to pay $70/mo, which drops to $60/mo after the first year. So not everyone is paying the $50/mo rate.
polpo··on Colorado Town Offers 1 Gbps for $60 After Years of Battling Comcast
Longmont, just south of Fort Collins, was the first city in Colorado to build out a municipal ISP, and it’s inspired surrounding cities to do the same. It’s where I live and it was a not-insignificant reason why I chose to move here. So far it has been a resounding success for the city. The buildout completed on time and adoption rates are higher than initially expected (the city planned for 37% but the last number I saw was around 54%). In my experience, the service has been so good as to be totally invisible. And I know my $50/mo rate will never rise. I wish Fort Collins the same experience. The fact that they both cities have municipal electric service will help this significantly.
polpo··on Apple to Deprecate Scripting Languages in Future Versions of macOS
It’s a big deal for Homebrew, which is written in Ruby and uses the version shipped with macOS to install itself.
polpo··on Quora pays thousands for posting questions
Ask MetaFilter: https://ask.metafilter.com/ It costs $5 to get an account that lets you ask or answer, and they have paid moderation staff that keep answers on-topic and high quality. The signal-to-noise ratio is quite high.
polpo··on Flying for Thanksgiving
The SSID for the WiFi at SFO is called “#SFO FREE WIFI”. It’s named as if someone has a wireless hotspot in their backpack running on a battery pack trying to steal the login information for your bank.

I had the same reaction the first time I saw the WiFi SSID at SFO. “Surely that can’t actually be the name of the official WiFi here. Let’s let it keep looking for networks...”

polpo··on Windows NT and VMS: The Rest of the Story (1998)
Also interesting is that Dave Cutler, architect of NT and VMS, was the first lead on Azure.
polpo··on The world's smallest desert is in Canada
Reminds me a bit of glades where I grew up in Missouri: areas where the topsoil is just a thin layer above the bedrock and can't hold much water. This creates small arid ecosystems, complete with prickly pear cactus and tarantulas. https://nature.mdc.mo.gov/discover-nature/field-guide/habita...
polpo··on Dell XPS 13 Review from a lifelong Mac user
Look at that screen, indeed: it has a 3:2 aspect ratio, which is practically unheard of in recent Windows laptops. It's good to see someone going for something taller than 16:9 (or even 16:10).
polpo··on Possible BGP hijack of 1.1.1.1
Cloudflare operates a public DNS server on 1.1.1.1 that has gotten a lot of attention since it was launched a few months ago. If a bad actor hijacks it, they can answer DNS queries with malicious answers, similar to the Amazon Route53 hijack that was used to redirect an Etherium wallet site to a fake server: https://www.internetsociety.org/blog/2018/04/amazons-route-5...
polpo··on Hijack of Amazon’s domain service used to reroute web traffic for two hours

polpo··on Hijack of Amazon’s domain service used to reroute web traffic for two hours
It means just that. Since they had control of DNS, they could have easily gotten a DV certificate, but in this case, they didn't and people clicked through certificate warnings.
polpo··on Apple starting to alert users that it will end 32-bit app support on the Mac
On the other hand, it is a bit crazy and impressive that OS X/macOS has had to support 32-bit x86 binaries for >12 years because they sold 32-bit Core Duo machines from January 2006 (introduction of Core Duo iMac) until August 2007 (replacement of Core Duo Mac Mini with Core 2 Duo version). 12 years of binary support because they sold 32-bit x86 CPUs for 20 months.
polpo··on Show HN: Wey – A fast, open-source Slack desktop app
Interesting to see this is from zcbenz, who was the initial creator of Electron. Slack's desktop app, which is based on Electron, is often criticized for its memory and CPU usage, so I'm wondering if the creation of Wey and its underlying Yue library are an answer/atonement for that.

polpo··on My Sony "smart" TV has updated itself and tried to force me to use a new app
I don’t trust Vizio since they watched people’s viewing habits without people’s permission: https://www.theverge.com/2017/2/7/14527360/vizio-smart-tv-tr...

That’s worse than the Samba.tv app in the OP since Vizio didn’t even tell people they were doing it.

polpo··on How to Clone Mineral Water (2012)
Imagine my surprise when I clicked the "a mineral water calculator" link and my browser downloaded an Excel spreadsheet. It'd be cool to port this to the web.
polpo··on Speed improvements in Python 3.7
A literal tab character is equivalent to 8 spaces in Python source (or 1-7 spaces if the tab is preceded by a number of spaces that is not an even multiple of 8). This follows well-established Unix standards.

So the following lines are at equivalent indentation:

    <SPC><SPC><SPC><SPC><SPC><SPC><SPC><SPC>foo
    <TAB>foo
Or do you mean that when you press the tab key in your editor when editing Python, you don't like that it emits 4 spaces instead?
polpo··on Qt 5.10 released
Well, there's GNUstep... I'd be interested in knowing if anyone has used it recently and how complete it is.
polpo··on The FastMail Security Mindset
Yes, they support SMTP and IMAP just fine. In fact, they're one of the few providers that actually support IMAP push with iOS's Mail: https://blog.fastmail.com/2016/12/21/what-we-talk-about-when...
polpo··on The FastMail Security Mindset
This is an entry in FastMail's series of Advent Calendar blog posts that they do every year. I'm glad to see them continue the tradition this year, and it's valuable to get this level of insight into a company that I trust with my mail. If you're interested in seeing more, check this year's first Advent Calendar post which has links to their calendars from 2014, 2015, and 2016, which are all worth reading if you're a FastMail customer or just interested in how running a mail hosting company works: https://blog.fastmail.com/2017/12/01/fastmail-advent-2017/
polpo··on Standalone Signal Desktop
There was a period in late 2014-early 2015 where NW.js stagnated, but since then it's been very actively developed. I found this 2016 comparison pretty even-handed and comprehensive; it'd be nice to see an updated version for 2017. http://tangiblejs.com/posts/nw-js-and-electron-compared-2016...
polpo··on Standalone Signal Desktop
They could use NW.js instead, which stays up-to-date with the latest Chromium version, including security updates. They usually release on the same day as Chromium. https://nwjs.io/blog/
polpo··on Microsoft Has Stopped Manufacturing The Kinect
Occipital still produces the Structure Sensor [1], which uses similar technology to the 1st generation Kinect. They've also recently introduced the Structure Core [2], a new generation, miniaturized depth sensor designed to be embedded into anything that needs that kind of sensing.

polpo··on A Closer Look at the $13B Premium Eyewear Market
I thought it was shady as hell when I got an explanation of benefits letter from my vision insurance (branded Aetna) with a return address of 4000 Luxottica Place.
polpo··on Adafruit's Read-Only Raspberry Pi
It's good to see a nice easy script to do this. I can confirm that mounting the SD card as read-only works great. For a couple years, I used a Raspberry Pi as an AirPlay receiver hooked to a set of speakers, and whenever I was done listening, simply turned off the power. I had / mounted read-only and never had SD card corruption.
polpo··on The iPhone X’s notch is basically a Kinect
If you want something to hack on, check out the Structure Sensor (https://structure.io). While it's mostly iOS-focused, you can get a USB hacker cable and interface it with a computer. (Disclaimer: I work for Occipital, makers of the Structure Sensor)
polpo··on Metal Slug 2 – reducing the slowdown (2015)
The arcade hardware (MVS) and home hardware (AES) on the Neo Geo have the exact same specs. And in the linked article the author is applying the fix to an MVS cartridge (which can be used in an AES system with an adapter).
