Logging all HTTP traffic is often unnecessary. It especially applies to website which include not only text content but also all kind of additional components, like JavaScripts, stylesheets, images, fonts etc. You can select what you would like to log inclusively, but it is much easier to do this by conditional negative selection. First define log format, then create conditional mapping, last thing is to specify logger with decision variable. For instance: This way we are not going to log any of additional stuff and keep only regular pages in the log. Will be more useful for further traffic analysis
For non-users of either Proxmox or Suricata: the first one is virtualization appliance which helps firing up virtual machines as well as LXC containers and the latter is network traffic security system which is able to identify (IDS mode) or even block malicious traffic (IPS mode). Suricata works just fine on Proxmox which is usually installed on Debian Linux, but sometimes there are some hardware/software compatibility issues which I’m going to tell you about right now… Having Proxmox server exposed in public space could be really not the best way possible. However if there is no chance for dedicated hardware,
Wstęp Dzisiaj wyjątkowo będzie po polsku na temat ChatGPT. Zadałem sobie nieco trudu i wypróbowałem jego “możliwości” z zakresu programowania jako, że zasłyszałem o takiej opcji. Moim ulubionym w ostatnim czasie tematem jest OpenCL, zatem…. JA: to napisz mi kernel OpenCL który służy do sortowanie liczb zmiennoprzecinkowych Dostałem sortowanie bąbelkowe…. i to jeszcze na floatach. W sumie to nie poprosiłem o double, więc nie mogę narzekać. Ale serio, sortowanie bąbelkowe, na GPU w OpenCL? Konwersacja Spróbowałem porozmawiać na ten temat z chatem tak aby dowiedzieć się dlaczego tak zaproponował oraz czy po kilku wskazówkach nie mógłby zrewidować swoich odpowiedzi na
First of all this SSD drive which I use is somehow faulty. It is a Goodram SSDPR-CX400-01T-G2 drive of 1TB. It have been working fine for few weeks until some construction worker made a electric short causing some abnormal frequences in wires resulting a faulty drives and memory sticks. One of victim was this drive: This drives for sure has some issues as at least one of tools shows that it as a problematic badblocks. Second of all in regular use it fails to run VM. It once switched into read-only mode in VM filesystem then after formatting it it
Having your own mail server could be useful but also sometimes dangereous. I am happy to see appliance such as iRedMail which cover variaty of topics regarding a somehow complete solution. I pick Ubuntu 22 on Hetzner. First you create DNS A record for your mail server and following by this a MX record pointing at that A record. Be sure to set proper hostname in the system. You can check it with: Ensure you have it set also in /etc/hosts and /etc/hostname. Next download iRedMail installer and iRedMail.sh script. It will prompt for various things but in my case
Until recently I though that having DNS subdomain entries provides enough obscurity thus should it be secure. If your DNS server does not offer transfering domain to another place then any subdomains should be hidden from public sight. Transfers, if enabled (or rather misconfigured) could be made by: Second thing is querying for ANY option, but it does not mean “all”: So, with disabled transfers and lack of exactly private entries while quering for any, you would think that you are on a safe side. And that is actually wrong. There are two 3 options on a table: Someone run
I’ve been playing around with several devices in a context of running OpenCL code on them. They have one common thing which is excessive heat coming out of GPU and heatsink being unable to dissipate it. I start with MacBookPro3,1. It has NVIDIA 8600M GT, which is known to fail. I assume that it may be linked with overheating. Second example is design failure of Lenovo Thinkpad T420s which has built in NVIDIA NVS 4200M. This laptop has Optimus feature which in theory could detect if workload should be run on discrete or integrated GPU. Unfortunately enabling either Optimus or
Among various computing devices I have there is one that stands out it is NVIDIA Quadro NVS 140M because it supports only FP32 (float) operations, but not FP64 (double). It is generally too old. In OpenCL we have both pow function which takes double and float parameters. The latter is called pown. I use first one to actually benchmark double precision computation.

Finally I got it working. I think so. This Proxmox installation is simple one, just single node for experiments which is half part. The other part is VM configuration. You may ask, what exactly for do I need GPU in VM? I may need because the hardware is capable of running several additional GPUs and I can use all of them at once in different configurations and even in different operation systems. Just like people do in cloud environments and this setup mimics such thing running server-like computer with datacenter-like GPUs on board. During this test I used NVIDIA GTX
