This render is btw very different compared to model displayed at Human Spaceflight Programme symposium.

He also says MOM data is still being received but its daily 10 minute home call has not been heard since 2 June 2021 per independent observation.

I need to write something about these stupid API things and I have next to zero knowledge of software stuff. Not writing these is not an option, if you understand this stuff and are willing to spare 10 mins, I would just like some guidance. Thanks!

Hi folks. Go 1.18 is on its way. It will be a great release and special feature is strings.Cut generics. I wrote a library to help you simplify your code and get rid of boilerplate: https://github.com/nikgalushko/fx.

I’ve worked with C++ and Python and even did web development for a while. Im trying to transition into systems Programming. I’ve taken operating systems and computer architecture courses and they all used c for obvious reasons and I loved those courses.

I’ve been trying to decide which book and loved Stephenson TCP IP Illustrated but I’m also a sucker for no starch press so I’m stuck between which book to choose.

I dislike how LPI doesn’t have exercises, but it’s not a deal beaker

Hey there!

Basically I'm trying to create an internal network a CT and a VM to talk to each other as I need them to have a local connection for something I'm trying to do. Whenever I try to make a bridge I'm getting this error, can anyone give me some tips on what to try? This is my current network config.

I've been a hamster for 25 years and owned other brands and find I have to check the manual when I need to program/change them. They also don't work with Chirp and have clunky programming software which doesn't let me copy/paste. The Baofeng is really easy and makes sense to me. Anyone else agree?

I have a few concerns/complaints about them:

1. Unsure if the signal meets FCC standards for spurs/harmonics. I don't know how to test/verify it or if it's a serious concern. I tried testing with a RTL-SDR software spectrum analyzer but the results were inconclusive. Results were worse than my late 90s HT but don't know if the FCC will be kicking down my door at 3AM over it.

2. Front end can overload making it deaf but this doesn't seem to be a problem at my home which is rural not near any powerful stations/noise.

3. Dislike the 'CALL' button. Wish it could be reprogrammed to jump to a calling channel. I have a 90s ADI HT with a programmable call button which was nice.

4. Audio level is low on TX so I have to talk loudly. Seems better in newer units? Anyone else have problems with low tx audio or was that only a problem years ago in the early units? I use a speaker mike with an enlarged hole over the element to help this problem.

Probably should've gotten a quality radio from the big-3 but I'm always worried I'll drop/break/lose it. Started with a UV-5R in 2013 and got a UV82 in 2019 then got a UV-50X2 recently. So far I'm liking the UV-50X2, the interface and setup is similar. I like being able to lock A and B together to display both the channel name and frequency.

I need to stop buying these cheap radios and get something respectable but I can't help myself. I have a problem.

Does anyone know of a website that provides guidance on when (day, week) to start seeds, transplant, and harvest? I'm thinking similar to almanac.com where you can enter your growing zone and plant and it will give you an idea on when to begin those actions, but I'd also like to enter that data into my google calendar. So, I need either an integration or addon that already exists or a site that provides a REST API to query that information.

Thanks in advance.

Hello! I’m making a backlit LED sign using an Adafruit Feather M0 Bluefruit & SK6812 LEDs. Here’s some photos & diagram of my setup: Imgur album

There are two LED strips - one around the outer perimeter of the sign, and one around the inner logo. They’re connected to pins 5 & 6 respectively at the moment, but I could wire them together if needed. The board will be powered via USB, and I’ll be able to easily tether it to my computer.

I’d like to create an app interface to control the color of each LED strip separately and optionally use FastLED effects. It’d be amazing if I could control it from my phone, but from my computer is also just fine. I just don’t want to keep coding every time I want the lights to change.

I’m pretty new to programming & working with FastLED, but I have some HTML & CSS knowledge. Could someone break down if that’s possible, how, and what I should use/learn? Thanks!

A IDE with a form, buttons, drop-down boxes, text fields and the works. I basically want to make a program that can connect and interact with an online mysql db.

I'm trying to spoof a MAC address on a WAN configuration, but when I attempt to make any changes, it says, "The MAC address of a VLAN interface must be set on its parent interface". Does anyone know where the option is to spoof a MAC address? I've looked everywhere, but I seem to be unable to locate the option.

Hello,

I have a Dedicated server at Hetzner running Proxmox, now I have a problem.

My VMs don't have access to the internet, and I want to also have access to the VMs from the internet.

My goal is that the Host system (Dedicated server) and all VMs share the same IPv4, as I only have one ATM.

I already tried multiple things I found trough google searches, but they don't seem to get me there (The best they were doing is to lock me out (unreachable SSH and Proxmox GUI) so that I had to boot into the rescue system, mount the ZFS Raid, change the interfaces file back to the last working configuration, unmount the ZFS and then use the KVM command and VNC to import the ZFS raid into the Proxmox install and reboot).

My /etc/network/interfaces file looks like this (Host system works fine, only VMs are inaccessible and also can't access the internet).

Thanks in advance.

And merry Christmas!

EDIT:

I got it working, if anybody has the same problem this will probably be your solution:

Enp2s0 is your physical interface.

95.xxx.xx.xxx/26 is your public IP.

95.xxx.xx.65 is the gateway provided by your host (in my case, Hetzner).

And the PREROUTING rules are kinda port forwarding the first p

Hi all,

just wanna share my current struggles at my job. So I‘m an IT consultant in the field of data management. Already working in this field since 5 years.

So far I mainly worked with graphical data tools. Last year I decided to switch to the programming-heavy field of data engineering.

Beginning this month I rolled on a new project to do Python data integration stuff. Now I need to develop a Django web interface for users to input data.

Holy sh*t! I just got the basics down with classes, control flow, working with files, sequences like dict, list etc. And now they ask me to create a (albeit very simple) website for data input?! Not only do I still need to recap basic Python stuff from time to time, now I also have to grasp this Django framework beast! Thanks to budget constraints it’s not even possible to provide me a more senior developer…

I‘m still torn between seeing this as a big chance to finally make the career switch on the one hand, and being pushed too hard here.

What are your thoughts on this matter? Any tips on how to cope with this situation?

I was learning about SVIs which can be used for remote monitoring or implementing SNMP for a VLAN, but when I went to configure the VLAN interface the ip address command was not available. I went from global configuration mode to interface vlan 11 which brought me to (config-vlan). And I only see about 4 commands. I have tried this on a Layer 2 switch and a Multilayer switch. I tried this on VLAN 1 and other VLANs I created. There is a telnet/SSH client and it asks for host name or IP address so I'm not sure if this is possible to experiment with. There is also a MIB browser so I'm confused. I tried doing some Googling and I'm pretty sure I'm using the correct commands.

Am I missing something or is this feature not available in packet tracer? I'm currently using Version 8.0.0.0212.

EDIT: Reboot fixed it. I am not amused by this apparent bug.

New to OPNsense and muddling through configuration. I'll be running a bunch of VLAN's that I've configured already as virtual interfaces on the physical LAN port. I believe the subnetting is all set correctly (no overlaps, correct masks, etc.). I'm getting errors as such when I attempt to start the DHCPv4 service in the dashboard, and the service will never actually start all the way:

/status_services.php: Warning! dhcpd_dhcp4_configure() found no suitable IPv4 address on opt3

I have a message like that for each of the VLAN's that I've enabled DHCP for.

Any ideas why this might be? Happy to post configuration or other log messages if they'd help.

Need to fill 250 Characters. Hopefully this is enough.
