I try to define buffer_size and get UDP fragmentation What is important to me is that each packet sent to the device must have a source and destination port - otherwise nothing will reach there. I have something similar in python, I split the file into parts and send it, but for some reason the other side does not receive IPv4 Fragmented IP protocol (I don't see it on wireshark). And I get buffer overflow on the sending script side.

Hello. I need to send a file over 1.5 MB between 2 network interfaces using UDP. My case is that communication must go on port 3007 (source port and destination port). It is very important. In standard operating systems using the IP protocol, system decides which source port use to send next portions of data. In this particular case we can't let the system decide, we have to force source_port and destination_port to 3007 The problem is that sending subsequent portions of data using the same source_port will result in a buffer overflow. Tested in python (UDP - socket). Do you know any way (ruby, python, java) that would allow me to send such a 1.5MB file using UDP where the source_port and destination_port will always be the same?

I think I can buy in similar price Sapphire Radeon RX 6700 PULSE 10GB GDDR6

Hi I am considering buying Arc A770 Phantom Gaming D OC 8GD GDDR6 graphics card, do you know if there is something better, more efficient for a similar price ?

Super, thank you ..

HI, I am replacing the server CPUs and I will stay with two Intel Xeon E5-2609 v4 from this replacement. Is there any desktop motherboard on the market that allows me to use these two Xeon E5-2609 v4 ?

How many degrees +/- I can lower VGA temperature by using WC ?

Corsair iCUE 7000X

I watched this movie, and I have some doubts about properly circulating air in my case. I ran the game Sniper Ghost Warrior Contracts 2 Butchers Banquet in 4K 120Hz at maximum detail.. The GPU temperature reaches max 80 ° C The video shows that the temperatures with FurMark running reach max 72 * C I wanted to ask you if my temperatures are normal, shouldn't I somehow cool more my GPU ?

Unfortunately, after many attempts to search for a case that will allow me to mount 2 VGA's, I decided to change the environment to RTX 1080TI Suprim X in Corsair iCUE 7000X RGB Black case. At last I could mount my sound card and I had one free PCI-E 16 slot !! It is surprising, however, that market offers nothing interesting for owners of 2 VGA cards

Impossible, laptop stays in one place all the time, no one sat on it, no one threw it out the window .. White stains appeared out of nowhere, suddenly, I haven't seen them before .. Hopefully this is not another production related screen defect the same as the butterfly keyboard .. Apple has recently been getting us used to production failures ...

Thanks Nayr438. Probably screen defect was from the moment I bought the laptop, I just didn't notice it. I wonder if such a defect may increase with time..

Are you able to write something more? What is the specificity of the problem, pressure issue is a production line problem and incorrect assembly? My equipment is 7 months old, I have not seen these white stains before, they appeared suddenly. The equipment was not moved anywhere, it stood in one place most of the time ..

Camera didn't capture it very well, in real they are more pronounced. This is not my equipment, but screen defect looks similar.. Does It Also Have Pressure Problems ? Take a look at this screen photo.. Also Pressure Problems ?
