Storing data in DNA?!

Honey

Hello,

So recently I was watching a youtube video, and they talked about new stuff revealed by Apple/Microsoft and along with several interesting announcements, they talked about Microsoft showing off their tech which supposedly stores data in DNA, and they can store tons of data in a relatively tiny amount of DNA due to high storage density.

The read/write speed is very very slow right now, they were just able to decode and read 40 bits of data from one full day of execution.

What do you guys think about this tech and its importance in the future? I personally was quite amazed soemthing like this was even possible and It kind of broadens my expectations for the future!

I am thinking to develop an android app for our organization and I want to connect to my website's database using the app, how to securely make a connection between app and website database in my VPS.
I would like to know if anyone could help me to start with.

CentOS 7 with XFCE & VNC

This is a brief installation instruction for VNC with the XFCE desktop environment on CentOS 7 Core (a.k.a server version without a GUI). I have written this guide using a CentOS 7.6.1810 Core x86_64 (minimal installation) VM based on Virtualbox (Ubuntu 18.04 LTS host). Depending on the virtualization technology you are using you might not have the same experience.

I'm not responsible for bricked system. I recommend to perform this installation on a clean and update to date system. Fiddling around on a system that has been modified before is mostly a nightmare and almost always a guarantee for something to go really wrong.

Let's start now.

1. Connect to your server and login as root.

2. Update your system using the command below:

Code:
yum update -y

I would also recommend to reboot the server after installing all updates. And after that continue with step three.

3. Install and enable the EPEL repository using the command below:

Code:
yum install epel-release -y

4. Install the XFCE desktop environment using the command below:

Code:
yum groupinstall "XFCE" -y

Depending on the Internet connection and the performance of the server the installation process will take a while now. Just wait until it finishes the download and installation. In my case over 280 packages had to be downloaded and installed. Even on a Intel Core i5 system running on SSDs only it takes a little while.

5. Install the VNC server using the command below:

Code:
yum install tigervnc-server tigervnc-server-minimal -y

6. Run the vncserver to generate the first configurations using the command below:

Code:
vncserver

You might be asked for a password. At this point you can set a password for VNC access. So type in a password you want to use to protect the VNC access to your server. You can also set a view-only password if you like.

8. Rename the existing xstartup file into xstartup.backup using the command below:

Code:
mv ~/.vnc/xstartup ~/.vnc/xstartup.backup

9. Create a new xstartup file with nano or any other text editor (following code is using nano):

Code:
nano ~/.vnc/xstartup

10. Paste the following code into the file

Code:
#!/bin/bash

 xrdb $HOME/.Xresources

 startxfce4 &

Save the content and exit the text editor. In nano you can use CTRL + O to save the content and CTRL + X to exit the text editor.

11. Set execution permission for the xstartup file using the command below:

Code:
chmod +x ~/.vnc/xstartup

12. Copy the X11 Xresources folder to the root home folder using the command below:

Code:
cp /etc/X11/Xresources ~/.Xresources

13. Run the vncserver again to start a session using the command from step six.

14. Now you can use the command below to check running sessions:

Code:
vncserver -list

You should see a session running at :1.

15. Create a service for the vncserver using the command below:

Code:
nano /etc/systemd/system/vncserver.service

16. Paste the following code into the file:

Code:
[Unit]

 Description=Remote desktop service (VNC)

 After=syslog.target network.target

 [Service]

 Type=forking

 User=root

 PIDFile=/root/.vnc/%H:1.pid

 ExecStartPre=-/usr/bin/vncserver -kill :1 > /dev/null 2>&1

 ExecStart=/usr/bin/vncserver -depth 24 -geometry 1280x800 :1

 ExecStop=/usr/bin/vncserver -kill :1

 [Install]

 WantedBy=multi-user.target

You can adjust the resolution from 1280x800px to what you prefer. Save the file and exit the text editor.

17. Reload the systemd service daemon and start the vncserver service with the commands below:

Code:
systemctl daemon-reload

systemctl start vncserver.service

You can use the command from step 14 to check if the session is running.

18. Enable the vncserver.service to be executed at boot:

Code:
systemctl enable vncserver.service

19. The VNC server will now listen on IP:5901. You need to open that port in your firewall:

Code:
firewall-cmd --permanent --zone=public --add-port=5901/tcp

firewall-cmd --reload

20. Connect to the server with a VNC client at IP:5901. Enter the password your set at step six.

21. Once logged in your will see a screen like this:
[Image: BqVG806.png]

Click on "Use default config" and it will generate a default taskbar and dock.

No idea about that XFCE PolicyKit error. Just click on OK and carry on I guess.

That's it I guess.

What have I learned? Don't attempt this on any system where you have no been working on before. You never know what exactly has been done to that system and what leftovers of possible failed attempts of previous installations there are. I could end up in a disaster like it did for me when I tried to help someone while on this clean VM it works without any big issues.

On the other hand it might be just crap OpenVZ that causes these issues. I'm not going to go into detail here. All I can say is that the system where I tried to help with has been modified before and had serve issues when attempting to install the GNOME environment (hence why I went for XFCE as that worked). So it had its fair share of issues before I even touched it. Everything actually worked until I rebooted it and it didn't come back up (neither SSH nor VNC). Would probably been half so bad if the server had a control panel I could use to start a emergency console and fix the issue that caused the server not to come back up.

P.S: I'm not really a big fan of CentOS and VNC. Sure it is really dangerous to run VNC as root. Just a tutorial for the installation though. If you plan on using this seriously I would suggest to create a special user for this and adjust a few things like the username in the service config and the PID directory. Also when running vncserver the first time you need to do it as the special user. So you bascially need to perform the whole setup as that special user and only use root where necessary (package installation, setting up permission, creating the service config and such tasks).

WARNING: If you use this guide on OpenVZ keep the following in mind! The desktop environment installs a network manager. This network manager is not capable of supporting and configuring network adapters on OpenVZ! What will happen is that it will override the network adapters with nonsense and the network will stop working after the first reboot. To fix this you have to disable the network manager service and reconfigure the network of the VPS through SolusVM (it's literally a button called "Reconfigure Network" in the control panel). After that the network connection should start to work again and also VNC should work.

Disable the network manager service using these two commands:

Code:
systemctl stop NetworkManager

systemctl disable NetworkManager

After that use the network reconfiguration button in SolusVM.

TL;DR: OpenVZ is whack crap.

VPS 15 (Hostlease) - Review - March 2019

Introduction
When I became the Giveaway Manager I thought to return my VPS 9 - Phoenix, that I had been so very happy with for almost a year, to create some distance between me and the VPSs. I have returned it to the VPS Pool for Giveaway during April.

No one applied for VPS 15 during the March Giveaway, so I decided to try it out for a month, and will return it for Giveaway in April as well. Objective was to write a review of the performance of VPS 15 during the course of its use during March.

It is probably unfair to compare a VPS of such huge specs like VPS 9 with VPS 15. Not that VPS 15 specs are anything to complain about, as they are very significant as you can see below. The performance is however very diffent and the speed of VPS 15 much slower, probably mostly due to the difference in connection speed between the two. 1 Ggbps (VPS 9) vs 100 Mbps (VPS 15). Having said that though, there is nothing wrong with the speed of VPS 15, and any one should be OK with using the VPS for normal resource applications. I'd guess however with users who require a lot of resources for games servers or possibly other heavier non-website applications I'm not so sure that I'd recommend VPS 15 for the application. I have however not tested VPS 15 for these applications, so it would be great if someone else would give VPS 15 a try for a games server and do a review on it.

Here are the specs of VPS 15:

Disk Size: 270 GB SSD
Monthly Traffic: 10 TB
Memory: 3 GB 3 GB vSwap
IP Addresses: 2x IPv4
Virtualization: OpenVZ
Location: Los Angeles, USA
Control Panel: None
Connection: 100 Mbps
Provided by: Hostlease

VPS 15 Host - Hostlease, Netherlands
VPS 15 has been generously donated by Hostlease, a sponsor of post4vps.com, and hosting company based in Heerde, the Netherlands. Hostlease specializes in business hosting and reseller hosting with focus on unlimited fast SSD disk space, data and cPanel features, and e-mails. It also provides unlimited Comodo SSL certificates for domains and subdomains. VPSs are an add on service and any one interested in a VPS should contact Jorgy (F7N) in the Forum.

Network, Performance & Reliability
When I first started to use VPS 15, the installation of VestaCP was super slow, but I think it was an extreme event as after a couple of hours things started to speed up, and still is good. This is what the speed was when I first started using the VPS on 8th of March 2019:

[Image: 8096222704.png]

Possibly the slow speed that I first encountered could also have had something to do with my ISP, however it soon sorted itself out, and settled into the following average speed (taken today) that is definitely OK for working with the VPS:

Usage
I've been using VPS 15 mostly for a WordPress blog. I loaded VestaCP, when it loaded slow, but I'm sure if I should repeat this that it would load must faster. It's still much slower than VPS 9 though. For WordPress this VPS works great. When I work with the Dashboard Plugins and themes they load and activate very fast. It's easy and fast to blog. However as previously said, I'm not so sure this VPS would be ideal for a Games Server, but then it hasn't been tested as a Games Server yet.

VPS 15 doesn't come with its own panel, so that would be a drawback for some who need the panel for reinstallation of the OS. However, for someone to own the VPS, the panel that is available is really great. At one stage when I was trying to change the port number of the VPS I was completely locked out of the VPS. Fortunately the panel that Hostlease has available allowed me to temporarily SSH in to fix the problem.

Things to Improve
Definitely the connection speed. 100 Mbps is much too slow for a large VPS like this. It would be great if the speed could be increased to the average speed one gets for the VPS of this size - 1Gbps minimum or faster. The sponsor mentioned the possibility of adding a panel for the user, and that would definitely be a great plus. Must say I'm a bit puzzled too with the location of the VPS in Los Angeles for a VPS host who is located in the Netherlands. I'd say one of the reasons for the lower speed has to be the far distance on top of the low connection speed.

Conclusion
All in all everything worked well with VPS 15, and support from the sponsor through F7N (Jordy) during the set up of the VPS was excellent. The Hostlease Website has a great chat feature “TalkTo” that works much better than Discord or support tickets. Also no captchas to worry about which had me smiling from ear to ear. We were able to conduct our business on TalkTo with maximum efficiency and the least waste of time.

I want to extend a special note of appreciation to Jordy for Hostlease's super support and the donation of VPS 15 for use by post4vps.
