Types of Coffee and Headaches? [on hold]

I love my coffee.

Though, when I have it, I get a headache. This was quite disappointing so I stopped drinking it.

Without thinking, I recently (a couple of months since stopped drinking) bought some instant coffee as I had a craving for it. Surprisingly it didn’t give me a headache, and it was not until I bought a coffee when I was out did I get a headache.

So, I think it must be coffee made from coffee machines (aka Expresso Machine/Manual) that trigger them.

I am just wondering if anyone knows why this is happening or advice if this happens to you.

Is there a collective term to describe “coffee” and “tea”? [closed]

Any term to describe both of them — coffee and tea collectively?

I wanted to call it beverages but that also includes drinks outside coffee and tea. Also, I could call it hot drinks but that would also include any hot beverages.

Any ideas to call both of them collectively?

How can I enable the “specialties” mode of a Flavia 500 coffee maker

We got two of these for our office. One has “Specialties” menu item, the other does not. The specialties menu item is mentioned in the user guide, but not how to enable or disable it. In the picture below, it’s the lower right grid item. It’s just blank/missing from one machine.

Bottle A contains a liter of milk and bottle B contains a liter of coffee.

Bottle A contains a liter of milk and bottle B contains a liter of coffee. A spoonful of coffee from B is poured into A, and the contents are mixed well. Liquid from A is then poured into B until B has one liter of liquid. Is the fraction of coffee in A greater than the fraction of milk in B, or vice versa?
[Hint: Giving things names will be super important here! You may also assume that your spoon isn’t giant.]

How do I design a Turkish coffee mixture?

I am trying to create a Turkish coffee mixture, by combining Colombian, Brazilian, Robusta and a few other types together in some percentage.
I could not find a base at which to stand in designing such mixture. What are the ideal characteristics of Turkish coffee ? How much caffeine, glucose, other chemicals should it contain ?

What ensures a better cup of coffee, a spotless grinder or freshly ground coffee?

I want to understand how I can make a better cup of coffee, so I recently purchased a Wilfa Grinder. However after reading the instruction manual it says that the ‘blades’ and bean cup cannot be submerged in water, only wiped clean. This means that you’re never really going to get it spotlessly clean like you can with a manual grinder.

So my question is which of the following two scenarios provide a better cup of coffee:

  1. Grinding from very good beans each time using the Wilfa Grinder, knowing that there will always be some old coffee residue on the blades.
  2. Buying 250g of the same very good coffee, but having it ground before delivery?

How to enable integrated GPU (with QSV) on Coffee Lake CPU in Ubuntu 18.x

I am so far unable to get Plex/ffmpeg to recognize the integrated GPU in my Core i7-8700 CPU. From my research it appears this is a common issue related to Coffee Lake CPUs, not just this specific model.

I started on vanilla Ubuntu 18.04, but also tried installing a mainline 4.17 kernel on 18.04, as well as upgrading to Ubuntu 18.10 with default kernel as well as latest mainline 4.18 kernel. None of these have resolved the issue.

Additional troubleshooting attempted:

  • usermod -aG video USERNAME
  • Editing /etc/default/grub with the following options:

    GRUB_CMDLINE_LINUX_DEFAULT="splash quiet i915.alpha_support=1"
    
  • Later changed to:

    GRUB_CMDLINE_LINUX_DEFAULT="splash quiet intel_pstate=skylake_hwp i915.enable_guc=-1 i915.alpha_support=1"
    

    (using sudo update-grub after each change)

  • Confirmed integrated GPU is enabled in BIOS

  • Installed latest graphics drivers from http://ppa.launchpad.net/oibaf/graphics-drivers/

  • Followed the entire process to build QuickSync-enabled binaries from here

Nothing seems to be working. From what I’ve read, my current kernel version includes support for Coffee Lake graphics, but they simply are not recognized. Here are some additional details to aid in troubleshooting:

  • The error Plex logs when trying to use hardware transcoding:

    ERROR - [FFMPEG] - No VA display found for device: /dev/dri/renderD128.
    
  • CPU: i7-8700

  • Motherboard: MSI Z370 Gaming Plus (MS-7B61)

  • Ubuntu version: 18.10 Cosmic Cuttlefish (development branch)

  • Current kernel: 4.18.0-7-generic

  • vainfo

    error: failed to initialize display
    
  • sudo lshw -C video

  • ls /dev/dri

I would really appreciate any help getting this working. Let me know if there’s any further information you’d like me to collect.
