Finally got myself a Lytro Illum!
I,v been wanting to buy one since it came out but the company who made it closed down in 2015..
Thoose fuckers just thrown everything in the trash and set it on fire, software, firmware, mobile app etc.. no open source, no archives, your expensive camera is now a paper weight! You’r welcome!
So i got myself a new hobby, started reverse-engineering the fuck out of it, luckily it’s based on android (api17), i have adb and it’s running a hidden DHCP server too so it’s coming along nicely :D
I’m planning to make a camera control mobile app for it and maybe some faster image processing, wifi sharing etc..
I love beeing in home office :D19 -
So, a rather unfortunate bug on the Minecraft website.
Minecraft allows you to change your name every 30 days. I was reverse engineering their API so I could use it personally.
On the username change form there are two fields: your desired username, and your password.
To protect myself from actually changing my name, I purposefully put in password123 so that it would fail. Then, I clicked "Change name" to monitor the network traffic.
Well that's when two unfortunate things combined.
#1: I used my last name to test. It's a unique word that is relatively short and very easy for me to type out of habit.
#2: That password field doesn't actually get validated.
So imagine my shock when I clicked "change username" and it WORKED.
And now my username is doxxing me for at least 30 days + the permanent name history

I often times write code and think to myself "I don't have to comment this, it's obvious what is going on", only to find myself back at the same code, figuring out wtf it does...1

why... WHY do I always attract all sorts of weird problems...
I feel like it makes me look incompetent :/
Like this side-gig. I had a client who brought us essentially half a rack (20 blade servers, 7 units of network equipment) and asked us to spin it up. No passwords, no topology - nothing. It was my first such "project".
So I'm setting it all up, using chatgpt and notions of vlan theory from college years ago. I managed to make smth work. Went away for the rest of the day. Hours later I come back -- no longer can connect to ovpn running on a MikroTik router. wtf... connect to office router's vpn, winbox via mac to the router to see wtf. Everything seems alright, except when I try to `/ip route print` it just hangs there. Tried a few times. -- same result. As if routes just got borked while noone was touching it. Found someone who's working with networks wtf, he said he's NEVER seen this happening. A router reboot sorted this out. That's weird problem #1.
I finished reverse-engineering and re-setting up the networking, sketched a topology with patching scheme and asked colleagues to take it all to the DC. They did it, connected it all up. 5 nodes aren't accessible via network. So I connect remotely to the router's openvpn and try to see what's up. Indeed, some servers are reachable, others aren't; even though MT switch (router's downlink) sees those servers plugged in with link up, servers don't see the link. I noticed some ports aren't trunking some VLANs. I started adding those ports when the winbox connection dropped out of the blue. 5-4-3-2-1-reconnecting... it reconnected. Yayy!! But wait, where is everything...? All interfaces -- gone (physical ones too). All IPs -- gone. All routes -- gone. Everything's gone. Half a minute later I'm disconnected again. The switch IP is no longer pingable. Servers plugged into it aren't reachable either. That's weird problem #2.
Then I figured I might try to see whether I can see anything from the router level. Try to ssh to it -- attempt was dropped, as if 22/tcp was closed. wtf? It was working in the office. winbox into it -- yayy, that works. Try to open a terminal via winbox -- a dialog pops up "Terminal <1> - not permitted (9)". wtf..? I Google this error up, it says that user is a member of group that does not have telnet and ssh permission. Indeed, I loog into groups -- the group 'admin' does not have them. Try to add them -- also not permitted. And I'm the 'admin' user, a single user in the router after a factory reset. How the hell else do I change permissions if even admin is flipped a finger.
That's weird problem #3
And now I look like an incompetent prick with two left hands who is only breaking shit.
And it's been like that my whole career
Why... How... ffs, that's getting annoying. Maybe I should downgrade myself to a QA. Problems find me themselves, I don't even have to look for them2
