X-Istence··on Red Hat Universal Base Image
There's no Python 3.6 UBI 8 image... at least looking at the charts in the blog post.

Why would they do a UBI 7 with Python 3.6 but not UBI 8?

X-Istence··on Pinebook – Powerful, Metal and Open Source ARM 64-Bit Laptop
I was using Google Docs for note taking, and as long as drive.google.com was already loaded, I could pop open the lid and create a new document in about 3 - 5 seconds.

I own one of the original Pinebooks, and for $99 it is a great little machine.

Comparing it to my MacBook Pro... it's terrible.

It has some flaws, and it may be underpowered for things like YouTube, it works flawlessly as a small note taker that has an extremely long battery life and a decent screen/keyboard. It's also really nice for having a Linux machine around that most dongles/serial consoles just work with when you head into the datacenter to deal with a Cisco device that isn't playing nice.

For the price point, you get a lot. As an owner of a Pinebook, I am looking forward to the Pinebook Pro.

X-Istence··on Red Hat Enterprise Linux 8 released
I mentioned my sys call filtering issue with eBPF taking up massive amounts of CPU time...
X-Istence··on Red Hat Enterprise Linux 8 released
No, it's maintained by a special interest group within Fedora:

Extra Packages for Enterprise Linux (or EPEL) is a Fedora Special Interest Group that creates, maintains, and manages a high quality set of additional packages for Enterprise Linux, including, but not limited to, Red Hat Enterprise Linux (RHEL), CentOS and Scientific Linux (SL), Oracle Linux (OL).

EPEL packages are usually based on their Fedora counterparts and will never conflict with or replace packages in the base Enterprise Linux distributions. EPEL uses much of the same infrastructure as Fedora, including buildsystem, bugzilla instance, updates manager, mirror manager and more.

X-Istence··on Linux 5.1 Arrives
Those who have used it have many battle scars that lead to us never ever trusting it again.
X-Istence··on Red Hat Enterprise Linux 8 released
The enterprises I've worked where we've used RHEL... epel is not allowed near a system, only officially sanctioned repos and updates.
X-Istence··on Red Hat Enterprise Linux 8 released
Some of the backports aren't nearly as fast or performant as using a newer kernel though.

For example eBPF was back ported (and also in CentOS), but running a syscall heavy work-load in a docker container on the older kernel about 50% of the CPU time was spent in the kernel filter.

I ended up moving our entire CI/CD platform to Ubuntu 18.04 and the performance issues went away and my workloads now run at full speed without slowdowns.

RHEL 8 comes with the 4.18 series of the Linux kernel that is already EOL. That's a shame and once again it will fall behind quickly :/

X-Istence··on Mozilla Firefox to Enable Hyperlink Ping Tracking by Default
Maybe now we can get rid of the god-forsaken javascript hell that does link tracking or the multiple bounces between servers before a redirect.
X-Istence··on Ikonate – fully customisable and accessible vector icons
Set the size of the icons really large, and then switch between the options, it does affect them, but very very minimally.
X-Istence··on Julian Assange arrested in London
The charges were suspended under Swedish law, however they can be brought back, they haven't been outright dropped.
X-Istence··on DopplerFi – Communication Between BLE and Wi-Fi by Injecting Doppler Shifts
UberTooth retails for $120.
X-Istence··on What Finally Killed AirPower
My iPhone can wirelessly back up to iTunes on my Mac Mini while charging on my wireless dock using WiFi.
X-Istence··on Warp – Mobile VPN
When most of those sites are hosted by Cloudflare, they already decrypt the TLS session at their load balancers before forwarding the request to the remote endpoint.
X-Istence··on Verifications.io Leaks Personal Records of 2B Users
SASL is also used with Dovecot/Postfix for example.
X-Istence··on What Finally Killed AirPower
Here's a wireless charger from Anker that sits at an angle that I use at my desk:

https://www.amazon.com/Anker-Qi-Certified-Compatible-Fast-Ch...

With the angle it sits at, when notifications come in FaceID will correctly ID me and unlock the device so I can at a glance see what the notification is.

As for syncing? All of that is done to the cloud, so that's not really something I care much about.

X-Istence··on Google launches AMP for email
I block loading of external resources, very much on-purpose. So in this case the AMP email will just, not work. Great.

^ cramforce works for Google on AMP.
X-Istence··on ARM and Intel have different performance characteristics: a case study
Interesting.

Here is the clang aarch64 output: https://godbolt.org/z/nH0y7F

X-Istence··on ARM and Intel have different performance characteristics: a case study
It's a shame that Godbolt doesn't have clang for ARM.
X-Istence··on Gmail confidential mode
Which is exactly what this does... and now I can't search my email for relevant information anymore.

This is a step back.

X-Istence··on Gmail confidential mode
Someone posted further up that when you send a "secure" email to an outside the company email address, they get a link to ope the email and have to enter a one-time code that is emailed to them.

So even forwarding is broken, as is search for those of us that search our emails a lot.

X-Istence··on Gmail confidential mode
Ugh... there are companies that did this sort of stuff for Outlook users, and it's a royal pain in the ass.

It's not searchable, it can't be archived for legal purposes this way, this is a nightmare for anyone that does business with you.

X-Istence··on AT&T Is Dragging HBO's Streaming Strategy Out of the Dark Ages
You can use a modern web browser to play the content. Safari works without issues for me.

No need for a extra device of any sort.

X-Istence··on AT&T Is Dragging HBO's Streaming Strategy Out of the Dark Ages
Creating a HBO Now account can be done through the web at https://hbonow.com/

You need a web browser.

X-Istence··on Scaleway cloud adds AMD EPYC instances
> (Reverse DNS? They require the forward address to point to you before they'll let you set it, as a "security measure".)

Many hosters I've dealt with have required this to prevent abuse from someone reading the rDNS and assuming the IP address is related to someone it is not.

X-Istence··on Nginx to Be Acquired by F5 Networks
A big F5 rig is basically Linux with a CLI/admin interface on top.
X-Istence··on Ghidra, NSA's reverse-engineering tool
He's talking about IDA Pro.
X-Istence··on Redesigning GitHub Repository Page
Using Github's tool for looking at the code tree is mainly so that I can grab a link and point someone to a line in a file.
X-Istence··on Redesigning GitHub Repository Page
If you've read one README on Github, you know to scroll down to see it on every other project. I would argue that it's not a steep learning curve, and it's not like the hide the scrollbar... we scroll in other websites without issue when we are looking for content, especially with ads being most of the content above the fold these days.
