text/gemini format, rendered to HTML. For the best experience, view through a Gemini browser (like Lagrange). Atom feed available. VRChat的性能有時非常的糟糕。常常地圖不支援 LoD，是路人開著 > 100萬三角形的avatar等等... 我的自認不算太差電腦，Ryzen 3700X + GTX 970 也只能在我的 home world 跑到36 FPS(Quest 2，中間用AirLink + Wifi 6跟主機連線。地圖：Rainy Attic + 鏡子)。 國外的工程師 fholger 也遇到類似的問題，於是開發了VR Performance Kit。在我的主機上由原先的36FPS： 提升到約略維持在72左右。相片中只有54是因為用了遊戲內的相機拍照，導致GPU必須多負荷相機的計算。 如果你...
Read more →VRChat is a great game. Probably the only MMO that is not a RPG (Besides one time my friend mentioned it's actually a MMO*ERP*G. Hehe). However the performance can be absolutely awful. Mostly maps not using LoD or avatars with 1M+ polygons. My PC, running a Ryzen 3700X + GTX 970 can only get a p...
Read more →TLGS is a search engine. Crawling is a very important part of it's oprtation. A crawler must follow links that it sees, retrive the page and follow more links on that page. While writing a basic crawler with DFS is relatively easy. Implementing a crawler that handles concurrent crawls well, runs o...
Read more →I decided to rewirite both my personal website and my Gemini capsule into a single service... Whoah.. that is so not UNIX. I should have just kept separate servers doing their own thing. But I have (I hope) good reasons to go the other way. Namely I want Atom feed because I want to explore how A...
Read more →Disaster just stroke me today. My Arch Linux laptop suddenly shutdown for no reason during system upgrade. - I'm 100% sure it's not a battery issue, I have like 23% left when I started upgrade - In any case. When I rebooted the system and got pass GRUB's boot screen. It just says "can't find linux...
Read more →I have been really annoyed by C++ recently. I love C++. It gives me the absolute best performance out of all languages with high level of abstraction. But it has so many problems that makes it borderline unusable sometimes. C++ gives me 100% control over very fine details on exactlly when and h...
Read more →gemi.dev have a interesting piece of small article I encourage people to read. For me as a search engine developer at leaset. He poses some important questions. This is totally true. The fact that Gemini is the size of early Internet is a blessing for developers. Commoncrawl[1] is a massive com...
Read more →My friends and I are considering to build a FOSS version of VRChat for fun, from scratch. Maybe just in case VRChat disappeared in the future. I trust that we have technical skills to do it. However, that gets me thinking, how would we run this place? It's likely building the software and infrastr...
Read more →This is my dream. I perfered to be called a CryptoPunk. But CyberPunk will do. Everyone is just a number. That's no a bad thing. No longer we sign contracts and leagal documents with our name. We sign them with private key(s) that we own. Our identities are no longer bounded to ours names. Now we...
Read more →This is just something I dream of.. And maybe actually build some day, when I have some extra cash or when I switch to a new laptop. The goal is as follows. But to be frank, it's so I can have the peace of mind knowing that no one, not even the CIA or Russian hackers can get into my laptop. I feel...
Read more →This is my thoughts on Drew's article[1] in which he explains his ideas of an ideal, open search engine. I want to share my thoughts too. Hopefully I'm qualified on writing about this. I am no researcher on related topics. But I do created TLGS. Hopefully some thoughts could help people realize a ...
Read more →I am a VRChat[1] player. I know it's very rare. Espically considering I'm on Gemini. Unlike most people on this protocol. I am not a pessimist when viewing technology. I think the Metaverse is a logical nextstep to the internet. But I don't think the one built by Facebook would ever live up to it'...
Read more →Drogon[1] is a fast C++ web app framework. It's fast in part by not abstracting the underlying threading model away. However, it also causes some confusions in our userbase. It's not uncommon to see issues and discussions about why responses are only sent after some blocking call, why calling a b...
Read more →Jami is a very cool distributed instant messaging program under the GNU project. The same GNU that brings you GIMP, glibc, Octave and much more. Jami clients communicate through the OpenDHT distributed hash table. However, the DHT only stores your message briefly. Thus, you miss your messages if y...
Read more →Modern software (espically from cooperations) are a privacy concern. Why in the world would a video conferencing program wants to know the spec of my PC and when I'm using it. And it's never opt-out. I think this in an unfortunate fact of competition between tech companies for their market dominan...
