Twts matching #processing
Sort by: Newest, Oldest, Most Relevant
In-reply-to » (replyto http://darch.dk/twtxt.txt 2024-09-15T12:50:17Z) @sorenpeter I like this idea. Just for fun, I'm using a variant in this twt. (Also because I'm curious how it non-hash subjects appear in jenny and yarn.)

One distinct disadvantage of (replyto:…) over (edit:#): (replyto:…) relies on clients always processing the entire feed – otherwise they wouldn’t even notice when a twt gets updated. a) This is more expensive, b) you cannot edit twts once they get rotated into an archived feed, because there is nothing signalling clients that they have to re-fetch that archived feed.

I guess neither matters that much in practice. It’s still a disadvantage.

In-reply-to » Interesting.. QUIC isn't very quick over fast internet.

@prologic@twtxt.net

They’re in Section 6:

  • Receiver should adopt UDP GRO. (Something about saving CPU processing UDP packets; I’m a but fuzzy about it.) And they have suggestions for making GRO more useful for QUIC.

  • Some other receiver-side suggestions: “sending delayed QUICK ACKs”; “using recvmsg to read multiple UDF packets in a single system call”.

  • Use multiple threads when receiving large files.

In-reply-to » @aelaraji how would that work exactly? Does that mean then that every user is required to have a cox side profile? Who maintains cox site? Is it centralized or decentralized can be relied upon?

@prologic@twtxt.net well…

how would that work exactly?

To my limited knowledge, Keyoxide is an open source project offering different tools for verifying one’s online persona(s). That’s done by either A) creating an Ariande Profile using the web interface, a CLI. or B) Just using your GPG key. Either way, you add in Identity claims to your different profiles, links and whatnot, and finally advertise your profile … Then there is a second set of Mobile/Web clients and CLI your correspondents can use to check your identity claims. I think of them like the front-ends of GPG Keyservers (which keyoxide leverages for verification when you opt for the GPG Key method), where you verify profiles using links, Key IDs and Fingerprints…

Who maintains cox site? Is it centralized or decentralized can be relied upon?

  • Maintainers? Definitely not me, but here’s their Git stuff and OpenCollective page
  • Both ASP and Keyoxide Webtools can be self-hosted. I don’t see a central authority here… + As mentioned on their FAQ page the whole process can be done manually, so you don’t have to relay on any one/thing if you don’t want to, the whole thing is just another tool for convenience (with a bit of eye candy).

Does that mean then that every user is required to have a cox side profile?

Nop. But it looks like a nice option to prove that I’m the same person to whom that may concern if I ever change my Twtxt URL, host/join a yarn pod or if I reach out on other platforms to someone I’ve met in her. Otherwise I’m just happy exchanging GPG keys or confirm the change IRL at a coffee shop or something. 😁

Interesting.. QUIC isn’t very quick over fast internet.

QUIC is expected to be a game-changer in improving web application performance. In this paper, we conduct a systematic examination of QUIC’s performance over high-speed networks. We find that over fast Internet, the UDP+QUIC+HTTP/3 stack suffers a data rate reduction of up to 45.2% compared to the TCP+TLS+HTTP/2 counterpart. Moreover, the performance gap between QUIC and HTTP/2 grows as the underlying bandwidth increases. We observe this issue on lightweight data transfer clients and major web browsers (Chrome, Edge, Firefox, Opera), on different hosts (desktop, mobile), and over diverse networks (wired broadband, cellular). It affects not only file transfers, but also various applications such as video streaming (up to 9.8% video bitrate reduction) and web browsing. Through rigorous packet trace analysis and kernel- and user-space profiling, we identify the root cause to be high receiver-side processing overhead, in particular, excessive data packets and QUIC’s user-space ACKs. We make concrete recommendations for mitigating the observed performance issues.

In-reply-to » @abucci / @abucci Any interesting errors pop up in the server logs since the the flaw got fixed (unbounded receieveFile())? 🤔

@prologic@twtxt.net I unbanned a few IP address I had blocked before the bugfix. I wasn’t being careful and just blocked any IP I saw making a large number of requests to my pod. That slowed the problem down but I think I blocked your and @stigatle@yarn.stigatle.no ’s pods in the process, oops.

In-reply-to » Now I'm about to do something that May...be... stupid, I'm no dev but I'll try and replace the U+201 in the script with a space and see what happens ...

@prologic@twtxt.net it actually does!

But I broke something trying to get rid of the random characters showing on my twts as mentioned here #k7tcqwq.
I taught it was as easy as swapping the ‘\u2028’ in jenny’s new_twt_from_file function but there’s a reason I’m not a developer (yet) 😅

It kinda got rid of them in a way but broke the new lines in the process. So I put things back the way the were till I figure out something else.

Anyone have any ideas how you might identify processes (pids) on Linux machine that are responsible for most of the Disk I/O on that machine and subsequently causing high I/O wait times for other processes? 🤔

Important bit: The machine has no access to the internet, there are hardly any standard tools on it, etc. So I have to get something to it “air gapped”. I have terminal access to it, so I can do interesting things like, base64 encode a static binary to my clipboard and paste it to a file, then base64 decode it and execute. That’s about the only mechanisms I have.

How Google Authenticator made one company’s network breach much, much worse | Ars Technica

🤦‍♂

WHY are these big companies treated as though they are the be all and end all of infosec? These are rookie mistakes Google’s making, at scale.

Unfortunately Google employs dark patterns to convince you to sync your MFA codes to the cloud, and our employee had indeed activated this “feature”. If you install Google Authenticator from the app store directly, and follow the suggested instructions, your MFA codes are by default saved to the cloud. If you want to disable it, there isn’t a clear way to “disable syncing to the cloud”, instead there is just a “unlink Google account” option.

Like, never ever put your multi-factor tokens into a single cloud storage location! The whole point of this being “multi” factor is that there is a separate, independent physical factor involved in the authentication process. If the authenticator app on your phone puts the tokens in the cloud, then it reduces the security that comes from having a second factor. This is basic stuff.

Of course, never ever use Google Authenticator. All it does is generate TOTP and HOTP codes, which you can do with any OTP app, preferably an open source one that’s been vetted.

Today I’m reading about how to save a copy of your secret keys outside a computer, using analog media, or sharing it by voice. For instance, for TOTP authenticators.

I found BIP39 coming from the crypto-wallets world:
https://github.com/bitcoin/bips/blob/master/bip-0039.mediawiki

The user has to write down this passphrase

fragile mimic expect ketchup truth between thunder visit expose output powder derive process disagree razor
Which is carefully designed to be checksummed and it’s easy to say on a call

Finally deriving it into a set of bytes like

Do you know some alternatives not related to cryptocurrencies? 🤔

I just received this email and I have some questions:

This email is from a trusted sοurce.

You received this abucci@bucci.onl because you have been disconnected from sending and receiving emails.

To continue using this email address we urge you to re-confirm if your account is still active on bucci.onl to officially unlock it to our default settings.

Re-confirm account (a link; removed)

※ This process is very important to help us protect your internet and fight malicious activities.

Since I administer bucci.onl myself, I’m a little confused. I don’t recall disconnecting myself from sending and receiving emails. I don’t even know how you disconnect someone from that. I also have never created the email address this email appears to be coming from, but maybe I should trust it anyway since they told me it’s a trusted source? Most puzzlingly, I’ve been sending and receiving emails just fine all morning, so I do not appear to be disconnected from anything? I want to help protect the internet and fight malicious activities, but what should I do??? 🤔🤔🤔🤔🤔

I’m playing around with snac2, which I think @stigatle@yarn.stigatle.no mentioned on here, and I have to say it’s extremely easy to set up and it’s been pretty straightforward so far. I wanted to experiment with having a presence on the Fediverse without going through the process of picking Mastodon vs. Gnu Social vs. Friendica vs. …, and I wanted to self-host instead of picking an instance of one of those. For now I’m abucci@buc.ci, but no guarantees that will remain stable; I’m just testing for the time being.

In-reply-to » Well, citizenship application is in. Now, the wait.

I remember when doing this process with my wife. During the halfway point we brought all sorts of documentation to show commingling of assets and showing we had “built a life together” .. we get to the interview and they just ask if we have a Costco card together. :|

good luck to you!

In-reply-to » And in the latest "don't store your passwords in the cloud" news, NortonLifeLock warns that hackers breached Password Manager accounts

@abucci@anthony.buc.ci ISO 27001 is basically the same. It means that there is management sign off for a process to improve security is in place. Not that the system is secure. And ITIL is that managment signs off that problems and incidents should have processes defined.

Though its a good mess of words you can throw around while saying “management supports this so X needs to get done”

JUHU! Finally! The new NAS runs. Oh boy what a process. First I had to restart and redow everything three times. Sometimes things are not sooo super obvious and then you really mess up. Who decided at Asustor that you cannot move home folders off of the Volume 1? And Why are the Asustor apps so bad? Beside that, the machine, the NAS, is really nice. Updraded to 16GB RAM and I finally have NGINX PROXY MANAGER running. Now I can setup all services with nice names!

Spent the last few days debugging network issues at work.

Exhausting. You never get a full picture. You poke a little here, poke a little there, … Form a hypothesis and test it. Eventually, maybe, you can narrow it down a bit to some segment or even some component.

A very time consuming process. Even more so if you try not to cause downtimes for your users.

I want a magical device that allows me to look inside a cable/fibre.

But hey, at least we got rid of a bunch of Cisco switches in the process. So there’s that.
