probability theory question: mean subsequent block time
  • Town currently still blocks Tor exit nodes (because it is getting ddosed by them) and rucknium understandably doesn't want to connect without it.

  • probability theory question: mean subsequent block time
  • Reply by rucknium:

    If I understand your question right, I think you're looking for the inverse cumulative distribution function (a.k.a. quantile function) of the Erlang distribution.

    The random length of time to mine the next block has an exponential distribution with rate parameter 1/t. The length of time to mine n blocks has an Erlang distribution with shape parameter n and rate parameter 1/t.

    The Erlang distribution is a special case of the Gamma distribution. The Erlang distribution's shape parameter must be an integer, but the Gamma distribution's shape parameter can be any positive real number. We can use the Gamma distribution if Erlang isn't given to us by our calculator.

    You would compute T in the R language with:

    qgamma(p = p, shape = n, rate = 1/t)/n
    

    The results of this simulation match the closed-form computation:

    t <- 120
    n <- 15
    p <- 0.4
    
    set.seed(314)
    
    mining.times <- matrix(rexp(n * 100000, rate = 1/t), ncol = n)
    
    mining.times <- rowSums(mining.times)
    
    quantile(mining.times/n, probs = p)
    
    qgamma(p = p, shape = n, rate = 1/t)/n
    # Divide by n to get the mean instead of the total

    Proposal for Generalized Bulletproofs Security Proofs is now open for funding!

    The proposal for Generalized Bulletproofs Security Proofs is now open for funding on the Monero Community Crowdfunding System.

    GBPs would be used to replace Monero's Ring Signatures with Full-chain membership proofs.

    Let's get this funded ASAP!

    New hosting provider! โ€“ monerosupplies.com

    Please report if you encounter any issues. Since about a week ago, the monero payment gateway doesn't seem to work and while setting up and testing the site after the migration I've ran into the site not always loading but that could be related to DNS propagation and hopefully resolves itself in the next few hours.

    Why we were down last night.

    Server showed as online on the hosting provider dashboard but it wasn't responding. After contacting support, this was fixed at some point.

    This led to a config file being reverted because of a setting I didn't change earlier which led to the page only showing "Server error."

    Everything should work again and in the future that config file shouldn't change by itself anymore. I still have no idea what the problem on the providers side was, let's hope it doesn't happen again :P

    What kind of RSS feeds should be added to monero.town?

    There is a lot we can do but it might become a bit spammy if we add too much. Some ideas would be:

    • Monero ecosystem releases (Monero, GUI, Haveno, Serai, etc) either in a special releases community or the regular Monero one
    • DarknetLive posts to the darknet community
    • Crypto news to the cryptocurrency community

    All of these feeds are of high quality and shouldn't completely spam us.

    What do you think? Any other suggestions?

    Onion instance (federation very limited)

    xmrtown4e5hj3yivdimt27np24atr7dyd7savkk6of5mdlykret7igqd.onion

    This instance doesn't share its backend with monero.town, in fact, it runs on an entirely different (and way less reliable) server.

    Edit: Subscriptions aren't working since remote instances don't know where to send their posts (doesn't work with onion addresses). This means that only manually searched posts actually show up, making the whole instance pretty useless ._.

    You can still view monero.town and the rest of the fediverse through federation. You can either put communities into the searchbar and subscribe to them (Example !monero@monero.town) or put entire links to posts from other instances into it to make them show up here.

    Since this instance is on Tor, it can federate inwards (pull content from other lemmy servers) but CAN'T federate outwards (interacting with posts on other servers). You can still comment and vote but only people on this instance will be able to see this. You are essentially siloed with a one-way window into the outside world.

    For now, registration is open because I don't want to manage applications on two instances at once. Don't abuse this or it will be shut.

    Monero.Town is now running on Lemmy v18.1 ๐ŸŽ‰

    Here is the changelog.

    This upgrade brings a ton of bugfixes and performance improvements.

    It also broke the nice custom theme we had ๐Ÿ˜… I'll try to iron this out but for the time being we will change back to a default theme.

    Meta FAQ
    How do I participate on Lemmy instances outside my own?

    If it's already discovered (see the next section on that) you can go directly by URL in this format. https://yourlemmy.server/c/coolcommunity@coolserver.com or by searching for coolcommunity in the search bar. You will stay logged in with your home server this way but can vote, comment, post using your current identity on that other server meaning you don't need a separate account. Neat right?

    Discovering: Hey I can't see [x] newly started community on my server! I can't find [y] popular community from my small server! What gives? (IMPORTANT)

    Some communities might not appear from All, until any logged in user of that server searches for it in the lemmy-ui (web) searchbar.

    For example, to "discover" coolcommunity @coolserver.com from instance yourlemmy.server, you would type "!coolcommunity@coolserver.com" within yourlemmy.server's search bar and wait 10 seconds. Ensure that community has at least one post that can sync, and even then it may take a while to actually appear in some cases. If you set the filter to "communities", enter the community in that format and press search and nothing happens, that means it is discovered. If it says No results, try again after 10 seconds, check that you have spelled and formatted correctly.

    That causes your server to "discover" it and will start syncing posts and be searchable and also available on apps like Jerboa. Only after it is discovered can you use a URL link to it in this format: https://yourlemmy.server/c/coolcommunity@coolserver.com I coined the term discovering here but in essence it's initiating federation and post-fetching from that community.

    I signed up but nothing happened/Some notification came up but I missed it. What do I do next?

    This server has a manual approval process. Usually requests are approved within 30 minutes but it can take up to 12 hours to get approved. Try logging in after an hour, if it works you are successfully registered. You won't get any notification at all of your approval unless you inquire about your application through outside channels like the monero matrix rooms.

    How do I find more communities?

    The communities page or searching for communities.

    Help! Why can't I see any/many posts and comments on an active thread?

    Check your Language settings. Select English, Undetermined and your native language(s) using Ctrl+Click in the webui.

    Where are the "Hot" and Important posts on Lemmy?

    Whichever server you decide with, you can use the All page from the home of your server, sort by Hot, New, Active. Just keep in mind again, if your server has few "discovered" communities you won't see much outside your own server. Subscribe to major, active communities that you might be interested in then you can look in your "Subscribed" page as your feed for buzzing posts.

    Statspage on number of Lemmy users etc.?

    Sure! FediDB, this page is also useful to find new servers to join.

    Anything else I need to know?

    Please be careful with what you share on the internet. This should be common sense as even content on Reddit can be archived before deletion.

    This post is based on this Lemmy FAQ.

    Monero.Town is back (and on Lemmy v18) ๐ŸŽ‰

    As some of you may have noticed, monero.town was only available for people signed into a Lemmy mobile app for the past few days.

    It looks like the Lemmy software had a bug that was exploited to DoS instances which of course happened on evening #1 of Monerokon. In an attempt to fix this DoS issue, I upgraded to Lemmy version 18 which required additional, badly documented changes to the config. Since I didn't have a laptop with me, there wasn't all that much I could do besides the initial analysis. That is why it took until today for me to fix the issue. I hope this wasn't too big of an inconvenience to anyone ๐Ÿ˜…

    Lemmy is still very new software and these are some of the growing pains. Please be reassured that I won't randomly abandon monero.town and will do my very best to never have to do another migration like house->town again.

    Improved default theme &amp; Monero themes

    The default theme now fills more of the screen on desktop and makes it easier to follow comment chains.

    If you are logged in, you can now select from three new Monero-colored themes:

    • Lemmy_Orange
    • Lemmy_Orange_dark
    • Monero-Town_dark

    In case you didn't know, Lemmy let's you use all kinds of custom themes via browser-exertions if you don't like the current selection. You can check out some pre-made ones here :)

    Image settings on this instance have been optimized ๐ŸŽ‰

    Storage is one of the biggest concerns in regards to instance resource usage, the new config should significantly improve storage efficiency via the following:

    • Uploads are now limited to a maximum of 1 MB
    • All uploads will now automatically be converted to the webp format and original file is discarded

    [Edited] New and improved optional theme ๐Ÿ‘

    This new theme makes posts more readable and leaves less empty room. It is also orange colored!

    To enable, go to the top right, to settings and select Lemmy_orange!

    Improved darkmode theme is the next goal.

    monero.house migration thread

    >Please create a new account on monero.town and post your old (or new) monero.town username with your monero.house account in this thread.

    I am sorry for the hassle, Lemmy completely breaks down if the domain name changes, which was sadly necessary because the old .house domain was creating huge trouble (it was used by a russian crypto scam in 2018 and is thus on many, many blocklists).

    >monero.house will start redirecting to monero.town by the end of the month.

    >By this point you wont be able to use your monero.house account anymore so please act quickly!

    Of course you don't need to pay the XMR registration fee again if you have already done so on house.

    If you come to this thread after monero.house has started redirecting to monero.town either do the usual social media verification again or if you have paid with XMR and still have the tx_id, provide that again. If you paid with XMR and don't have the tx_id anymore, contact @monerobull:matrix.org on matrix.

    This is a one-time thing, I don't expect that we will ever have to do something like this again.

    I plan for Monero.Town to stick around for a long time.

    Edit 27.06.2023:

    Monero.House is now offline.
