Cheap Wireless Lavalier Microphone Cracked Inside

2 Komentara

Wireles Lavalier Microphone - Packaging

Widely on the net this microphone is recommended as good for its price. So I got one, and I got quite disappointed. Well it does work but quality of the audio is not great. It has noise reduction turned on all the time (no option to turn it off) and it greatly degrades audio. Not that audio quality is reduced but it also makes it choppy, if you speak bit quieter.

It could be usable in some situations like outdoors recording where external noise covers a bit usable audio so degradation is less noticeable but there is another, more limiting issue: rechargeable battery in microphone lasts less than one hour. […]

Proxmox, DHCP, Multicast DNS

0 Komentara

There is a rule that server machines should always be on static IP. Proxmox is designed in that manner. You are supposed to manually set IP. I am not fond of that approach. Yes, IP should be static, but I prefer to assign IP using DHCP.

Fro some reason Proxmox does not have installed support for Multicast DNS. THat means zou have to access it using IP or assign domain to IP to access it by domain. You cannot use host name to access it using Multicast DNS request. I like to use Multicast DNS.

Dynamic configuration is helpful, when I have to set up device in my localnetwork but them move it to other network where it would be used. […]

RustDesk remote desktop

RustDesk (https://rustdesk.com/ , https://github.com/rustdesk ) is Open source virtual/remote desktop software like TeamViewer or AnyKey. It is on par with them in functionality, except that RustDesk is Open software, meaning free. It gains large popularity, as it does job well, and especially because commercial alternatives became unreasonably expensive unacceptable for noncommercial or low profile use.

Actually, there is one more big difference – You can host RustDesk on your own. This makes you independent from third parties. It makes it even more favorable.

Author of RustDesk actually recommends using self hosted servers for simple reason – public servers that are available, and free to use, actually do cost money. […]

Firefox kutije za višestruko prijavljivanje na sajtove

, 2 Komentara

Nakon dužeg vremena testiranja u Fajerfoks je konačno za stalno ubačena opcija kutija (Containers). Njena namena je da omogući korisniku da potpuno izoluje otvorene stranice, praktično, kao da ste otvorili različite veb čitače.

Ova opcija je namenjena pre svega za povećanje stepena privatnosti, ali ja sam prepoznao jednu veoma praktičnu primenu – sad mogu da se na isti sajt prijavim iz Fajerfoksa više puta, koristeći različita korisnička imena.

Za svakodnevnu upotrebu ovo i nije tako važno, ali kada radite veb razvoj ovo je prilično korisna stvar.

Takođe može biti korisno ako, na primer, treba da na Fejsbuku koristite više naloga. Ovo će kao korisno prepoznati oni koji održavaju Fejsbuk naloge za svoje klijente. […]

, , , 0 Komentara

BNC konektor je jedan od retkih koji se izrađuje u verziji za impedansu od 50 oma i impedansu od 75 oma. Za neke primene vrlo je važno koristiti odgovarajući konektor. Kada kupujete konektor lako je, kupite onaj koji vam treba, ali šta ako imate konektor kome ne znate karakteristike?

Pogledajte kako je napravljen. Konektor od 50 oma sadrži prsten od izolujućeg materijala dok 75-omski konektor to nema.
