Most consistent Powerpoint editor for 2020?

I love Linux to death. My one and only Linux negative is the lack of Powerpoint compatibility. Powerpoint flat out wins the presentation wars, and now that MS Office 2019 is out, running MS Office 2010 via Playonlinux feels incredibly dated.

As I know, there is no documented way to run MS Office 2019 via Wine, and even MS Office 2016 can be a bit buggy. So, what are our options in 2020? For those of you who need to use pptx for work, can you help discuss your workflow and comment on the options here?

* LibreOffice
* FreeOffice
* WPS Office (free)
* WPS Office (premium)
* MS Office 2016 (Wine) ?
* MS Office 2019 (Wine) ???
* Office 365
* Other online services (e.g. Canva)

Libre is great as a standalone system, but its pptx portability fails big time for me. I have little experience with the others on Linux, besides MS Office 2010. It seems that WPS does a good job displaying pptx files for me. I'm considering using Office 365 to begin my work and coupling that with WPS locally, though I believe the 365 version is limited compared to the desktop version. Thoughts? What's your system?

Netdata release v1.20!

Hey all,

Our first major release of 2020 comes with an alpha version of our new **eBPF collector**. eBPF ([extended Berkeley Packet Filter](https://lwn.net/Articles/740157/)) is a virtual bytecode machine, built directly into the Linux kernel, that you can use for advanced monitoring and tracing. Check out the [full release notes](https://github.com/netdata/netdata/releases/tag/v1.20.0) and our [blog post](https://blog.netdata.cloud/posts/release-1.20/) for full details.

With this release, the eBPF collector monitors system calls inside your kernel to help you understand and visualize the behavior of your file denoscriptors, virtual file system (VFS) actions, and process/thread interactions. You can already use it for debugging applications and better understanding how the Linux kernel handles I/O and process management.

The eBPF collector is in a technical preview, and doesn't come enabled out of the box. If you'd like to learn more about\_why\_ eBPF metrics are such an important addition to Netdata, see our blog post: [*Linux eBPF monitoring with Netdata*](https://blog.netdata.cloud/posts/linux-ebpf-monitoring-netdata/). When you're ready to get started, enable the
eBPF collector by following the steps in our [documentation](https://docs.netdata.cloud/collectors/ebpf_process.plugin/).

This release also introduces **host labels**, a powerful new way of organizing your Netdata-monitored systems. Netdata automatically creates a handful of labels for essential information, but you can supplement the defaults by segmenting your systems based on their location, purpose, operating system, or even when they went live.

You can use host labels to create alarms that apply only to systems with specific labels, or apply labels to metrics you archive to other databases with our exporting engine. Because labels are streamed from slave to master systems, you can now find critical information about your entire infrastructure directly from the master system.

Our [host labels tutorial](https://docs.netdata.cloud/docs/tutorials/using-host-labels/) will walk you through creating your first host labels and putting them to use in Netdata's other features.

Finally, we introduced a new **CockroachDB collector**. Because we use CockroachDB internally, we wanted a better way of keeping tabs on the health and performance of our databases. Given how popular CockroachDB is right now, we know we're not alone, and are excited to share this collector with our community. See our [tutorial on monitoring CockroachDB metrics](https://docs.netdata.cloud/docs/tutorials/monitor-cockroachdb/) for set-up details.

We also added a new [**squid access log collector**](https://docs.netdata.cloud/collectors/go.d.plugin/modules/squidlog/#squid-logs-monitoring-with-netdata) that parses and visualizes requests, bandwidth, responses, and much more. Our [**apps.plugin collector**](https://docs.netdata.cloud/collectors/apps.plugin/) has new and improved way of processing groups together, and our [**cgroups collector**](https://docs.netdata.cloud/collectors/cgroups.plugin/) is better at LXC (Linux
container) monitoring.

Speaking of collectors, we **revamped our** [**collectors documentation**](https://docs.netdata.cloud/collectors/) to simplify how users learn about metrics collection. You can now view a [collectors quickstart](https://docs.netdata.cloud/collectors/quickstart/) to learn the process of enabling collectors and monitoring more applications and services with Netdata, and see everything Netdata collects in our [supported collectors list](https://docs.netdata.cloud/collectors/collectors/).

## Breaking Changes

* Removed deprecated bash
collectors apache
, cpu\_apps
, cpufreq
, exim
, hddtemp
, load\_average
, mem\_apps
, mysql
, nginx
, phpfpm
, postfix
, squid
, tomcat
If you were still using one of these collectors with custom configurations, you can find the new collector that replaces it in the [supported collectors list](https://docs.netdata.cloud/collectors/collectors/).
* Modified the Ne

tdata updater to prevent unnecessary updates right after installation and to avoid updates via local tarballs [\#7939](https://github.com/netdata/netdata/pull/7939). These changes introduced a critical bug to the updater, which was fixed via [\#8057](https://github.com/netdata/netdata/pull/8057) [\#8076](https://github.com/netdata/netdata/pull/8076) and [\#8028](https://github.com/netdata/netdata/pull/8028). **See** [**issue 8056**](https://github.com/netdata/netdata/issues/8056) **if your Netdata is stuck on v1.19.0-432**.

Any hash checker tools that utilize all cpu cores/threads?

Would it be possible to create a sha256sum tool that can utilize all cpu cores and threads?
When one has huge files as input, it can take forever on one thread/cpu core.
I was wondering if it was possible to generate a .sha256 file through all cpu cores and threads?

Thank you in advance.

Looking for opinions/experience Kubuntu vs Ubuntu for gaming/Steam

I am planning on switching my main desktop over to linux. I have narrowed it down to Kubuntu vs Ubuntu. I really really like KDE over Gnome but, I am wondering what the issues are when it comes to gaming or steam. From everything I have seen everything leans towards gnome but, I am wondering if that is just due to that is what Ubuntu and Debian use as default or if there is a real reason for it.

Other things I plan on doing on this install is: cybersecurity tools, office, programming, running virtual machines, small amounts of video recording and editing, possibly some streaming in the distant future. So if you know/experienced issues with any of these feel free to chime in.

Feel like a simple maintenance monkey for hire

Recently been doing routine maintenance on on peoples computers for money. I've only had three customers so far, all friends and family. Been payed $40-$60 for each job.

On Windows I cleaned up viruses and bloatware(ultimately speeding up the system). For others I've just installed a distro of their choosing on a laptop.

I had been studying computers on my own for a few years. And now it's like I've found my side hustle. 😙

Is this how I got hacked last month?

Linux noob here. I had a file named testfile321.php in /public\_html/testfolder321/ on my server last month... it was a test file I forgot to delete. The file testfile321.php had 0755 permissions, allowing anyone to execute. Here was the code in that file:

​

`<?php`

`exec('node/bin/npm install jt-js-sample');`

&#x200B;

That's all there was to it. There was only one other person who knew about the existence of testfile321.php in my public web directory, a coder I was hiring. My server suddenly got infected by phishing malware and started sending out thousands of phishing emails, and people were replying to my server's email address saying I was sending them phishing emails.

I've since restored my server to a clean image before that file ever existed, and changed all the passwords to everything, including the root password.

Now my question is this: was it possible for him to execute commands and gain remote access through testfile321.php, seeing as how it had 0755 permissions? Did the existence of that file allow him to inject his own commands and gain root access? Can someone ELI5 what commands someone would've injected through that file to gain root access and/or install malware?

Looking for a graphics tablet for Fedora or OpenSuse

Hi, I am looking for a non-Wacom graphics tablet that would work on Gnome Wayland (Fedora) and/or KDE plasma(OpenSuse). I have spent hours researching and while some models by some manufacturers (eg XP-Pen and Huion) seem to work with Linux systems, there is conflicting information from users - for some it works, for others not.

Would it be wise to choose a model that has Android support, as it might have better chances of working on Linux?

Thanks.

I wrote a bash noscript to select a country using dmenu and open the respective YouTube trending page

https://www.youtube.com/feed/trending shows trending for your currently selected country. To view it for another country, you need to either change it manually in the menu or append a country code, such as ?gl=DE. This becomes tedious if you want to switch to multiple countries.

With this noscript you can select the country using `dmenu` and the respective trending page will open. Change the browser in the last line to your own browser.

How to use: just run the noscript with no arguments. You need to have `dmenu` installed.
