  • Who's developing the web3/crypto startups? Developers developers developers! (с)
    Together with the team, I've selected the top ~4,000 projects from CoinMarketCap and found GitHub profiles for them, and then aggregated the entire history across all repositories. Source: almost 2 years ago
  • [OC] Trying to keep in step with the crypto world, I developed a self-service for monitoring the crypto market by various metrics - top coins by audience growth, development activity, sentiment on Reddit, Twitter mentions, etc. As a result, it gives me fresh insights on 7,700 crypto assets daily!
    Our team collected this information from sources like Discord, Reddit, Twitter, Github, etc. In the first step, we've collected all known cryptocurrencies from several registries and got more than 7,700 of them. In the second step, for each of them we've found the corresponding Discord server, subreddit, Telegram channel, GitHub profile, etc. Then all we need - is web scraping and official APIs, and the data is...

  • Can anyone tell what is this?
    This is not opera.com it's "api2 dot com" so it's a malware site posing as an opera one by including opera in its name. I had a popup like this. It opened every time I opened the browser. Turned out it was coming from a video downloader extension. Source: 11 months ago
  • Is there a way to download the official browser through a torrent or a mirror link?
    The opera.com domain is banned where I live but I still want to download the browser without a VPN (because those are also banned). Is there a torrent link or an alternative/mirror link where I can download the latest Opera One release? Thanks! Source: 12 months ago
  • Opera Adblocker pinging opera.com?
    Apparently it "urgently needed to be removed off the network" (bullshit, you could've blocked opera.com, dumbass) I don't see why its so bad to have one kid with an unmanaged browser, like seeing "your browser is managed by your organisation" sucks enough. They disabled basically everything good about Chrome, for a time, they locked down the performance tab so we couldn't even use battery saver. Source: 12 months ago
  • Opera Adblocker pinging opera.com?
    One day, I got called to my Deputy Principal's (Dep. For short) office because my laptop was doing wacky shit to the network. He informs me that my laptop had sent 64k pings to opera.com. It was about the 2nd term, we receive new laptops every couple of years. He first told me about my searches for a VPN, which I guess is on me. But when he brings up the 64k pings, he tells me whatever the app is doing it has to... Source: 12 months ago
  • How big is the chance of getting malware while downloading roms?
    I use uBlock Origin on Chrome but it is available for Opera GX as well. You install it by finding uBlock Origin in addons section of opera.com and then clicking the "Add to Opera" button. Source: about 1 year ago
