Auditing GitHub users' SSH key quality

https://blog.benjojo.co.uk/post/auditing-github-users-keys

Auditing GitHub users’ SSH key quality. If you have just/as of late gotten an email about your keys being revoked, this is because of me, and if you have, you should really go through and make sure that no one has done anything terrible to you, since you have opened yourself to people doing very mean things to you for what is most likely a very. However one of the other side effects of this is that it means that. I started running the streamer on 2014-12-27 and now 2015-01-09 I have quite a few keys:.

Lessons from APL, a "lost" language

https://blog.benjojo.co.uk/post/2014-05-26-APL-the-lost-language.md

Lessons from APL, a “lost” language. A few weeks back the forum that I go on often held a obfuscation challenge, and people joked around about submitting a entry that was coded in APL. APL (A Programming Language) is a programming language that was developed at IBM by mathematician Kenneth Iverson. It is mainly infamous because of its need to have a separate keyboard installed to code in it:. The challenge involved making a simple program:. NoColor - noCIN - noCONT - silent. Overall though I though it wa...

I may be the only evil (bit) user on the internet

https://blog.benjojo.co.uk/post/evil-bit-RFC3514-real-world-usage

I may be the only evil (bit) user on the internet. Almost every year a joke RFC. Is made on April 1st (these have caught on so well, that it’s now common to see more than one of these every year), or April Fool’s Day, and some of them are pretty great. Here are some of my favourites:. SONET to Sonnet Translation RFC1605. Hyper Text Coffee Pot Control Protocol (HTCPCP/1.0) RFC2324. UTF-9 and UTF-18 RFC4042. TCP Option to Denote Packet Mood RFC8541. The Null Packet RFC6592. Scenic Routing for IPv6 RFC7511.

Monitoring SNMP less devices with ease

https://blog.benjojo.co.uk/post/monitoring-wifi-devices-without-snmp

Monitoring SNMP less devices with ease. In the consumer world you will likely encounter networking devices that don’t have a easy way to poll for their network stats, or in some cases you hate. So much that you would rather go to rather worrying lengths to avoid it. Either way, In my flat, I have two AP’s, one is a Ubiquiti Unifi AP-AC. And another is a cheap USB powered AP device. That I use to patch up the last dead spot in my flat, Running OpenWRT. Can we avoid scraping ifconfig? As always, the /proc.

The strange case of ICMP Type 69 on Linux

https://blog.benjojo.co.uk/post/linux-icmp-type-69

The strange case of ICMP Type 69 on Linux. I run collectd stats. On many of my servers and one thing I enable on some (but not all) of them is the protocols plugin. This plugins pulls from the. Counters and submits them to the stats server. You can view the data in a human friendly way on linux by running. Which should give you something like this:. However I always thought it was strange when I saw this:. IcmpMsg: InType0: 941 InType3: 364 InType11: 9388 OutType3: 384 OutType69: 11265. Since type 69 is ...

NPM has a bunch of useful stuff on it, however you could in life while using NPM get this:. Stack Error: pre versions of node cannot be installed, use the - node dir flag instead.

Detecting anycast addresses and more

https://blog.benjojo.co.uk/post/path-detection-for-anycast

Detecting anycast addresses and more. Anycast networks are a pretty interesting way to fix quite a few issues with networked services that involve needing global spread. One of the interesting things is that a computer cannot really tell (unless it has a full routing table of many providers in more than one geographic location maybe) that a IP is using anycast. Not my IP, not even routable) and lets say the direct translation to a phone number was. And a anycast IP was. This is an anycast address. Discov...

Reverse Proxy + Cache for Minecraft

https://blog.benjojo.co.uk/post/minecraft-reverse-proxy-plus-cache-on-demand

Reverse Proxy Cache for Minecraft. The major sucker of it, is that it generally eats at least 1GB of ram, even when its doing. And no one is connected to it. That’s kind of sucky. To fix this issue (since it is the only one I think I can fix out of this) I have written a really simple reverse proxy for Minecraft, Infact it can be used for just about and TCP port based game if you ignore some of the other options, but for now I will go into how it can be used for Minecraft.
