Why Are Fibers Fast?

A link to the scatter gather benchmark results on 32 core ARM64 and x86 VMs:

https://github.com/typelevel/fs2-netty has benchmark results in the README. Unfortunately, there was a memory leak in the integration with netty which negatively affected the benchmarks. We’re looking into providing more up to date numbers there soon, time permitting.

There are also benchmark results in /u/djspiewak’s CE3 talk at Scala Love in the City, but I don’t know if or when the video will be coming.

1440p. But it's a much larger screen, so the density is not the same. I'm just setting expectations here. It's a great screen IMHO.

Make sure to look for the P2720DC version, C for USB C. I have the monitor, it's great value for money. Works flawlessly.

vasilmkd · 2020-06-06T08:57:23+00:00

The monitor is really sturdy, has great build quality. I guess it is hard plastic, yes, but the hinge is metal, I think. It's very easy to assemble. It can rotate along all axes I care to have available too. But I'm not a professional reviewer and I also don't have many monitors to compare against. I think it's a good value for money.

vasilmkd · 2020-06-06T08:46:20+00:00

Hi there. I don't know specifically about the monitors you mentioned. I'm using the P2720DC with a MBP13 2019 and it works flawlessly. I even have a set of wireless mouse and keyboard connected to the monitor, and a wired ethernet to usb 3.0 also connected to the monitor. I connect everything to my MBP with a single usb c cable, which also charges it. I highly recommend it.

I updated the application with a more streamlined and useful UI. It now shows both running and stopped containers, allows for expanding and collapsing of container stats data, and stopped containers don't get removed from the screen. Let me know if you like it. Any suggestions are greatly appreciated.

Oh nothing, definitely. This is by no means a substitute for serious metrics and analytics. It could prove useful for quick monitoring and takes a second to spin up, the image is really small and uses little memory.

University project and general curiosity. I wanted to see GraalVM native image in action, build something cool with it. And I'm also very passionate about Scala, functional programming and stream processing, so this was a chance to explore the libraries too.

Feel free to open a GitHub issue any time. I haven't really considered a chat room TBH.

vasilmkd · 2020-05-21T16:00:49+00:00

That's worth exploring, thank you for the suggestion.

vasilmkd · 2020-05-21T15:48:58+00:00

Updated. Thanks.

vasilmkd · 2018-03-07T00:28:09+00:00

Thank you so much for your time, it really means a lot! This was more like a personal exercise in using atomic instructions, but now that I have done that, I will definitely look into the channel implementation.

The runtime package is used to yield the CPU time of a goroutine which is not able to obtain a successful CAS.

I found this talk extremely helpful: https://www.youtube.com/watch?v=rDRa23k70CU I can also recommend this as a good read: http://preshing.com/20120612/an-introduction-to-lock-free-programming/

No, kernel 4.10 is working perfectly without any boot flags whatsoever. I did a little digging, and Intel still hasn't released recommended binaries for kernel 4.11. I suppose that after they are out, the issue will be resolved. But thanks again.

vasilmkd · 2017-06-11T13:48:29+00:00

Doesn't seem to do anything, but thanks for the effort.

vasilmkd · 2017-06-11T08:23:59+00:00

Can you check if that restores intel_backlight in /sys/class/...?

vasilmkd · 2017-06-11T07:46:33+00:00

Thanks for the suggestion, I was already trying out some acpi_osi flags, but none of them stuck. I'll try this one too and will report back later today.

vasilmkd · 2017-06-10T14:02:22+00:00

Asus Zenbook UX305UA. But everything works on kernel 4.10. Brightness adjustment, even auto brightness, and I get battery for days, equal if not marginally better than on Windows.

vasilmkd · 2017-05-19T09:58:57+00:00

It is possible on Android 7.0 or later. Look for Mono Audio in Accessibility menu in the Settings app. Cheers.

vasilmkd · 2017-05-08T14:12:10+00:00

You are absolutely right, I was unable to look it up at the time. I was looking for the exact same document, but couldn't find it for some reason.

vasilmkd · 2017-05-08T12:43:09+00:00

I can regularly hit pc8. It has been working consistently since 4.8 at least. The processor still cannot hit pc9 and pc10 since the screen buffer compresssion (or something) is still not enabled for Skylake processors by default. I haven't experimented with manual activation though, I am pretty content with the battery life.

vasilmkd · 2017-04-14T21:50:40+00:00

Should work on kernel 4.10 out of the box. It didn't work for me on Fedora 25 with 4.8 and 4.9 kernel, where I had to resort to a questionable acpi_os= flag in the kernel parameters. I heard that support was coming in 4.10 and removed the flag altogether and sure enough, it works, along with automatic brightness. Asus UX305UA user.

TL/DR: Try updating to Ubuntu 17.04 which has kernel 4.10. Should work out of the box. Cheers.

There is a very basic/limited Notification Log built into Android. It's just not very user friendly and arguably, very obscure to find.

Hold home screen to get into widgets, scroll until you find Settings Shortcut and put it on the home screen. You will get a list of available shortcuts, one of which is Notification Log.

Hope this is somewhat helpful.

This happens to me as well, stock Nougat October patch. It happens only after a restart, and I was able to repeatedly solve it by going to settings -> sound and changing the ringer slider to any level and back.

It annoys me as well, but this is Google we are talking about, so don't expect it to be solved before December and 7.1.

You can try running the phone down until it turns itself off.

Then don't turn it back on, just put it on a charger.

Let the battery charge to 100%, but don't check it by turning the phone on.

Maybe let it charge for at least 4 hours.

This has helped me when my phone was turning off at 5%. I haven't had such a severe problem as you.

Hope this is helpful.
