arthurfm··on Ryanair, Hamiltonian Cycles, and using graph theory to find cheap flights (2018)
Great website, although I have one minor nitpick.

When searching for flights to or from London it's not clear which airport is which out of LTN, LGW and STN.

Would it be possible to add the IATA code in brackets (after London) and possibly another item in the dropdown for all London Airports?

arthurfm··on Chrome OS has stalled out
> This means the ThinkPad X131e had under 3 years of support if you bought it brand new like many school districts did in 2015.

The ThinkPad X131e Chromebook was originally released in February 2013 [1] and has received five years of Chrome OS updates from Google. From March 2017 onwards, new Chrome OS devices receive 6.5 years of support [2] and in November 2019 many received a further year of support on top of that [3] so the update situation is a lot better than it was.

School districts purchasing X131e Chromebooks would have known at the time of purchase that they would stop receiving updates in February 2018 [4]. Being two plus years into their lifecycle is not really Google's fault. The districts need to do better due diligence.

As you mentioned, EOL dates for all Chrome OS devices are published in an article on Google's website [5]. To get the most life out of a particular Chromebook model it needs to purchased as close to launch day as possible. That's what I always try to do when purchasing Chromebooks where I work.

It's also worth mentioning that the X131e is supported by Neverware's CloudReady until 2025 [6] so the Chromebooks don't have to be thrown away when Google stops supporting them.

arthurfm··on Office noise bothers some people more than others
> My biggest triggers are people who eat crunchy food with open mouths; people who slurp their drinks; people who are oblivious to their environment and sing loudly in open offices.

For me it's people who talk while eating and who read emails aloud while writing them. So annoying!

I have had to resort to taking noise cancelling headphones to work.

arthurfm··on How Untitled Goose Game became a real video game
> Because every sale on the storefront that charges more is less margin?

There's a simple solution to that. Just charge more for the game on Steam et al.

For example. Untitled Goose Game is £15.99 on the Epic Game Store, so charge at least £18.39 on Steam.

arthurfm··on Everything Is Getting Louder
My last car (a W177 Mercedes A Class) had an option to disable the acoustic locking verification sound in the infotainment system. I turned it off straight away.

The beep is unnecessary since the lights also flash when locking/unlocking.

That's not entirely true. When you get to the 'Let's connect you to a network' screen just click the 'I don't have Internet' link in the bottom left corner [1] and then choose 'Continue with limited setup' [2]. This will take you to the local account creation step.

arthurfm··on Thomas Cook collapses, stranding 150k UK holidaymakers
The Guardian article mentions that hotels have to wait up to 3 months to be paid by the holiday company. I can see why the Tunisian hotel did what they did, but you are correct that their business relationship is with Thomas Cook, not the holidaymakers.

Meanwhile, Thomas Cook holidaymakers were anxious that they might be evicted from their hotels or charged again for their holidays. Holiday companies do not normally pay hotels until up to 90 days after guests have left.

Do hotels typically have insurance that covers situations like this?

Traces of faeces have been found on every single McDonald’s touchscreen swabbed in an investigation by metro.co.uk. Samples were taken from the new machines that have been rolled out at restaurants across the country – every one of them had coliforms.

Senior lecturer in microbiology at London Metropolitan University Dr Paul Matewele said: ‘We were all surprised how much gut and faecal bacteria there was on the touchscreen machines. These cause the kind of infections that people pick up in hospitals.

By far the worst PC component I have come across containing LEDs is Kingston's HyperX Fury RGB SSD [1]. It's a 2.5" SSD with 75 LEDs! These LEDs generate so much heat (70°C+) that the drive thermal throttles and either prevents the operating system from booting or causes significant performance issues [2].

11. As expected and previously announced, support for 32-bit processes/i386 architectures has been removed.

Printer drivers are also deprecated in Catalina. A future version of macOS will remove support for them completely.

24. “lpadmin: Printer drivers are deprecated and will stop working in a future version of CUPS”. man lpadmin on a macOS Catalina system for more details. It seems that Apple wants admins to move from lpd/smb/socket (JetDirect) to AirPrint.

arthurfm··on Raspberry Pi 4
It wasn't The Verge that originally said the Pi4 struggled to play YouTube videos [1], it was Tom's Hardware [2].

Tom’s Hardware’s review notes that the hardware is able to handle many everyday tasks such as web browsing with up to 15 Chromium tabs, light image editing using GIMP, and document and spreadsheet work using LibreOffice. Unsurprisingly, the sub-$100 miniature PC has its limits. It reportedly struggles with full screen video playback from YouTube for example, even if you turn down the resolution to 480p.

Tom's Hardware were using a pre-release OS so it's possible the issues with video playback were caused by this?

It’s important to note that, at launch time, some important Raspberry Pi software doesn’t yet work on the Pi 4. To run Pi 4, you’ll need to download a brand new build of the Raspbian OS, Raspbian Buster. And not everything runs in Buster yet. During testing, we found numerous Python libraries or other required packages that weren’t compatible with the new OS.

My biggest problems involved video playback. If I wanted to watch a YouTube video, I had to keep it in a window, because even in 480p resolution, it was jerky at full screen. The other task I’d like to perform is playing retro games, but as of this writing, the Retropie package of emulators doesn’t work with Pi 4.

During extensive hands-on testing, I found that, while the 4K at 30 Hz is tolerable, little things like the movement of the mouse pointer are a bit sluggish. If you have a 4K screen, you’re definitely better off going for the 60 Hz mode, but note that the added voltage may also cause your CPU to get hot and throttle more easily.

While surfing the web, looking at still images and just enjoying all the extra screen real estate of 4K is great, video playback is the Raspberry Pi 4’s Achille’s heel, at least as of this writing. Whether we were attempting to stream a 4K video or use a downloaded file, we never got a smooth, workable 4K experience, either in Raspbian Buster or LibreElec, an OS that runs the Kodi media player. Several H.264 encoded videos, including Tears of Steel, did not play at all or showed as a jumble of colours. Even the sample jelly fish videos that the folks at Kodi recommended for my testing appeared as still pictures with no movement. Clearly, there’s a lot of optimization that still needs to be done both on the OS and software side to make the Raspberry Pi 4 capable of playing 4K video.

Unfortunately, even streaming 1080p YouTube videos is a challenge at this point. Running at 1080p resolution, full screen video trailer for Stranger Things showed obvious jerkiness. However, the playback was smooth when I watched the same clip in a smaller window. The same problem occurred, even when I dropped the stream’s resolution down to 480p.

Playing offline 1080p videos works well, provided your screen is at 1920 x 1080 or lower resolution. A downloaded trailer of Avenger’s Endgame was perfectly smooth when I watched it using the VLC player.
