Anyone know of a small library to preview/quick-view 3D model files, supporting .stl?

I'm trying to find a way to quickly preview all the STL files on my machine. Similar to gnome sushi (pressing spacebar to preview an image)...

Closest I found is g3dviewer, but it doesn't seem to support STL, oddly. Not sure why, it's a pretty common format for 3d these days, especially for people doing CAD/3d-printing, but maybe that's why... the project seems old... considering breaking open the code to add stl support, but thought I'd ask first.

having hell of a time install a particular version of wireshark

Hey everyone,


I work for a company that required a specific version of wireshark to be installed on the system, we inherited a system that has the most up to date version.


I can remove that version using apt-get uninstall wirehshark


however, how do I manually install wireshark version 2.6.10


I have the tar, and from what I can read online you run ./configure


however there is no configure in the wirehsark directory after it upacks.


what gives?

Learning Linux

So within the past couple weeks I have been thinking of switching to Linux but I literally have no idea on where to start. I enjoy using Windows but I have been wanting to get more technical with things as I dont think I will ever get anywhere in the career I want to if I dont push myself to learn.

Hoping someone can help me on where to start with Linux and if dual booting is still a good idea in 2021??

Windows if falling in a way I've never seen before

First of all I use 2 operating systems rn, Linux and Windows, I used to use 3 but I decided I need a break from MacOS and it was a bad decision.

I bought a machine for 1.2K$ 2 years ago moving from my MBP. I felt good and started poking around with Windows to personalize it a little. After 2 years my computer starts to feel outdated. Windows updates constantly are breaking things, search bar is an utter nightmare, when I try to search for a file it never does a good job, when I try to search for a program in my computer that I installed 2 seconds ago it says I don't have it.

Windows store provides zero to none apps that you can actually use and enjoy.

I have constants problems from juggling between two settings menus, one from 2010 and the newer one from Windows 10. They never bundled it together.

Windows feels like a bloatware compared to Linux or MacOS. It feels like an old truck driven by a drunk into a steep hill of darkness. I honestly hate it and looking how it was surpassed by competition it makes me sick. I am making a Linux hopping party with a friend soon and I don't want to look back, ever.

Literally nothing except gaming works well in this enviroment. Everything feels old, clunky and shitty on a machine that should be still flying. I have no viruses, I never bloated the machine with anything and it gets eaten out by a 2013 MBP.

In 2 weeks tops I am out of Windows for life.

I am happy to see a community like that existing because it gives me courage to ditch something that I was so sure I will be using my whole life.

exeCute now runs transparently exe and bat files on Linux

​

https://preview.redd.it/dz2k5etnryd61.png?width=1080&format=png&auto=webp&s=fd3d6346760c13a20a8f516e234b48cf705560d7

Using bare wine and dosbox usually gives problems when launching a mixture of Windows and MS-Dos applications.

Launching a Dos program on Wine sometimes fails, as Wine performs all kinds of custom configurations intended to use Dos programs in particular cases.

So a while ago I created exeCute for being able to tell the difference among the two types, and launching the exe directly into the right emulator. With the parameters that will look closer to a native experience.

But still running Dos programs was difficult if they required a disk image, as that needed making a custom noscript for each game under this category.

Today I have fixed that. If you launch such program, exeCute will look for disk images in the same folder and mount them on D. If there are none, the exe folder will be used as D instead for maximum compatibility.

In summary, now launching exes on Linux only requires clicking on the desired exe.

Here's a demo:

Light Linux Distros

I am a Windows user and I am tired of it's battery and resource consumption on my laptop even when I'm doing something as simple as writing down notes in Word. That's why I am compiling a list of the lightest Linux distros so I can test the boot time, memory usage, CPU usage, and software load times to find a fast and efficient Linux OS for my laptop when I'm at school so I can have an easier load on my battery when I'm out all day at classes. I will report my findings here once testing is completed.

So far for testing I have:

Linux Lite 5.2

Puppy 9.5

Debian 9

Peppermint 10

​

Tell me your favorite lightweight distro to be included in my testing! (I've really never used Linux... like... ever so this will be interesting to test out)

Problems with the ping command

As the noscript indicates I'm having a few problems with the ping command on my computer. I'm using Pop!\_OS. When I ping a machine (my Pi in this case) which is on my local network, I only use it to check when it is back online after a reboot. So when the pi goes offline, I should see the following output

```
PING 192.168.1.108 (192.168.1.104) 56(84) bytes of data.
64 bytes from 192.168.1.104: icmp_seq=1 ttl=64 time=0.149 ms
64 bytes from 192.168.1.104: icmp_seq=2 ttl=64 time=0.143 ms
64 bytes from 192.168.1.104: icmp_seq=3 ttl=64 time=0.161 ms
From 192.168.1.103 icmp_seq=4 Destination Host Unreachable
From 192.168.1.103 icmp_seq=5 Destination Host Unreachable
From 192.168.1.103 icmp_seq=6 Destination Host Unreachable
```

But instead of looking at "Destination Host Unreachable" after the 3rd icmp_seq, it will "pause" the output and will resume after the host is back online. So this is what I see in reality.

```
PING 192.168.1.104 (192.168.1.104) 56(84) bytes of data.
64 bytes from 192.168.1.104: icmp_seq=1 ttl=64 time=0.135 ms
64 bytes from 192.168.1.104: icmp_seq=2 ttl=64 time=0.142 ms
64 bytes from 192.168.1.104: icmp_seq=3 ttl=64 time=0.143 ms
64 bytes from 192.168.1.104: icmp_seq=20 ttl=64 time=0.140 ms
64 bytes from 192.168.1.104: icmp_seq=21 ttl=64 time=0.141 ms
64 bytes from 192.168.1.104: icmp_seq=22 ttl=64 time=0.153 ms
64 bytes from 192.168.1.104: icmp_seq=23 ttl=64 time=0.206 ms
64 bytes from 192.168.1.104: icmp_seq=25 ttl=64 time=0.264 ms
64 bytes from 192.168.1.104: icmp_seq=26 ttl=64 time=0.243 ms
64 bytes from 192.168.1.104: icmp_seq=27 ttl=64 time=0.154 ms
64 bytes from 192.168.1.104: icmp_seq=30 ttl=64 time=0.146 ms
64 bytes from 192.168.1.104: icmp_seq=31 ttl=64 time=0.148 ms

```

And as you can see, it skipped the output after 3rd icmp_seq and resumes the output normally with the 20th icmp_seq. And notice another abnormality between 27th and 30th. I'm running wired with my Linksys gigabit router and my NIC is an Intel I211 (rev 03). The aforementioned abnormality of that weird pause between the 27th and the 30th icmp_seq is more apparent when I ping google i.e. over the internet where the ping is much higher than 30 ms.

To check if my router was at fault, I tried doing the same thing - ping my pi and ping a google server. I did that over WiFi from my MacBook Pro and everything worked as expected, there were no weird issues as I mentioned above. I also tried hooking the MacBook with a wired adapter on the same port of the router where my computer was previously connected - to check if that particular port on my router was faulty, but I didn't face any problems on that specific port as well.

Has anyone else encountered this problem? I'm unsure if this is a distro specific problem as Intel NICs are pretty reliable and work well with Linux and I would assume neither the NIC nor router are at fault here.

Considering I can't see when there is a "Destination host unreachable" and the ping sequence resumes without any `icmp_seq=29 destination host unreachable`; All I normally see is "Huh, there's no problems with my internet connection. Everything is fine. I'll just press control C (`^C`) and quit out of ping. *then I see the packet loss* Wait, I didn't see any errors in the output, how did I get packet loss more than 0%?"

I don't know what is causing this. Any help will be awesome. TIA!

Edit: I'm using the `terminator` terminal emulator and I checked if it was a terminal emulator problem by doing the same thing in Pop's default `gnome-terminal` but I got the same result. This the first linux distro I've used on this computer and hence, I'm unsure if this is a Pop!_OS specific problem. Running `ping -V` shows `ping from iputils s20190709`.

AMD or nVidia low-end gpu for server ?

Hey I need to buy a lowend GPU for my machine (running debian) - it runs headless most of the time (but the board wont boot without GPU). Currently I am using very old PCI-E1 gpu and I am suspecting it might be source of crashes.


So I am looking to buy a new GPU. I've read that AMD has currently amazing opensource drivers. So is buying AMD here better than nVidia ? Currently looking at either Geforce 710 or Radeon 230.

Archman OS: Why you should avoid using it

There is a plenty GNU/Linux distributions out there.

Maybe you are curious to test new distributions. Arch Linux is a great distribution. It is free and open source distribution, secure, fast but it is targeted to advandced users. Many Arch Linux based distributions does exists, and you can check it on official site and Distrowatch.

One of these distribution is turkish intelligence MIT ("milli istihbarat teskilati)", not related in any way to Massachusetts Institute of Technology) funded/related Archman OS. The project is hosted in Turkey, but they are using Cloudflare services, so you can't say where they actually are.

The first point is their effort to steal Arch Linux identity. They do not have any relation to official Arch Linux project, but they say that they offer official suport for Arch Linux and arch based distributions. How it is possible that?

A time ago the projects leader tulliana was dismissed by Manjaro project after trial of political influence in favor of the corrupt and antidemocratic turkish government and clear confrontation with Philip Müller. This is not a surprise since his involvement in MIT affairs.

Archman OS is hosted somewhere in Turkey, where it is hard to say. The projects official site has no clear WHOIS data.

The official mirror is located in Bursa, Turkey and do not supports secure HTTPS connections (see this and this). The secondary mirror is from "Anadolu Panteri" - a hobby project by islamist GNU/Linux activist.

Some of the source code is hosted by Gitlab, but you can't actualy build a ISO from files found there. Binary prebuild ISO files are located in Sourceforge. As you can check, provided ISO files are incompatible with official Archiso.

The developer is not providing any security check: gpg public keys and signatures are missing from "official" provided repositories and ISO files.

The name Archman (r) is a copyright violation itself. Arch linux has a manual documentation project named archmanweb project. In Archman OS official site they say the name come from "Arch Linux" and "Pacman", but they do not have any rights under these products and marks. Using the name "archman" is not ethical without any written permission from Arch Linux project. As stated in official Arch linux trademark policy:

>Building on Arch Linux or for Arch Linux. If you are producing new software which is intended for use with or on Arch Linux, you may use the trademark in a way which indicates the intent of your product. For example, if you are developing a system management tool for Arch Linux, acceptable project noscripts would be "System Management for Arch Linux" or "Arch Linux Based Systems Management". We would strongly discourage, and likely would consider to be problematic, a name such as ArchMan, Arch Management, ArchTools, etc. Furthermore, you may not use the Trademarks in a way which implies an endorsement where that does not exist, or which attempts to unfairly or confusingly capitalise on the goodwill or brand of the project.

As you see Archman OS is not free (as in freedom) open source, and not affiliated in any way with Arch Linux. The projects is closed and vague security with clear affiliation with official turkish government. Before using it think twice, othervise you should wander why your data is stollen by turkish government. You have been warned.

Is doas a good alternative to sudo?

I updated my sudo recently for the bug which supposedly escalate root permissions by some brute force attempt.

In an effort to find the solution (not just updating it), I came across doas. I read some articles by dedicated openbsd application subexecutor and some community post on r/BSD. Those post and articles are quite old and may not fit well in current scenario.

The thing which is not clear is, is it really better than sudo (if not best)? The OpenDoas repository appears to be updated quite regularly though it isn't popular among most of the Linux distros (Arch doesn't have documentation, which is pretty odd).

Do you guys prefer Doas over Sudo? If you do, please elaborate.

Gamestop stock price noscript

I made a really short noscript (just one curl command piped into other commands to filter it) to display the Gamestop stock price (or any other stock price of your choosing). It is not the pinnacle of noscripting; it could be a lot shorter, but it has worked reliably for about 24 hours now. I'll put the command below as well as a link to the GitLab repository where I will be updating it if it breaks.

echo "\$"$(curl -s `https://finance.yahoo.com/quote/GME` | grep 'data-reactid="50">' | awk -F "data-reactid=\"50\"" '{print $(NF-3)}' | cut -c 2- | sed 's/<.*$//')
