> Google reportedly used their Android users to sniff APs

Pretty sure that's how it works across all phones. I know that's how Apple gets their location services database at least.

It does fall back to the GPS receiver if no internet and no cache but I suppose it's just more power efficient and not on anyone's minds that people would MITM for this purpose.


Yes and no.

For the intended purpose of learning? Not at all. If you're legitimately interested in the subject, you'll learn more on your own.

For improving your prospects? Definitely. Say you were unlucky enough to be born in the third world. University is the easiest route into the first. I've spent almost £80k between tuition fees, rent, and living expenses over the past 3 years, all my own money from bug bounties, freelancing, and jobs/internships. I could've probably lived a comfortable life back in Malaysia with that much savings while working an average job. But the cap on my potential has definitely been raised several times that just by having a UK visa and a pathway to residency.

Also, I learnt this lesson way too late: it's not about what you know, but who you know. I wasted my first two years here mostly doing individual projects. Even though the 3rd year is the most busy, I'm making active effort now to work with professors on their projects. Some are genuinely interesting and at the same time, they have the ability to link you up with people with similar interests. If you can't seem to find people at your level IB Uni, it's because you haven't tried going the indirect route via professors. They know everyone


For me, it's a nice way to keep up with what's happening without going through the effort of following the right people in the right places. It's a stretch to call it a community though, although perhaps my definition may be a bit old fashioned. Anonymity just doesn't really fit. I do like seeing the diversity of opinion though. It's rare in real life to have people verbalize their disagreements, much less in a well researched manner.


I still can't believe that certain IOS APIs are locked to paid developer accounts only (PacketTunnel, Shortcuts, etc.) such that you can't even sideload your own app onto your own phone with these features. It's not very well documented that it's paid either. Spent forever a couple months ago figuring out why my code wasn't working before giving up and opening my wallet.


You also have to request and be granted permissions for various features like local network access

It’s quite an authoritarian wake up experience to go thru the whole process. It’s very clear their hooks are deep.

But then on the flip side so are the threats. Shitty world.


A £20 USB microphone from Aliexpress. The audio quality is so much better than laptop or headphone microphone


Which one? Looking for a cheap way to improve my current setup. Thanks!


I've never actually compared so I don't know if there's a better one for the price but the one I bought was "Zealsound RGB Recording Microphone With Articulated Arm/USB Condenser Mic with Tripod"

The sound quality doesn't feel crazy but definitely usable for anything I need. Also seems to filter out my laptop fan noise which is much appreciated


うっせぇわ (Usseewa) was a big one back during COVID. I remember people hacking into the school broadcast system and playing it everywhere.

For me, CP-SAT is the "dumb" solution that works in a lot of situations. Whenever a hackathon has a problem definable in constraints, that tends to be the first path I take and generally scores top 5


Happy New Years! I can't believe it's already 2026. Posting from a flight back to the UK. Having wifi in the sky, we really are living in the future.

2025 wrapped: https://duti.dev/blog/2025/2025-in-a-nutshell/

Putting this down as my 2026 goal: At least one commit a day. Stop putting things off.


Currently in China (as a visitor). Wireguard literally just works (to a VPS). Mullvad works as a commercial provider, just slower. Xray-core (vless, Trojan) if you're paranoid. I have my own proxy over syncthing relays https://github.com/acheong08/syndicate which I use to proxy to my home in the UK (residential IP) without exposing any ports.

I get rate limited to around 10mbps in Chongqing. Was slightly higher in Beijing.

Does this offer any benefits over Tailscale and having an exit node at home?


I do have that as well. I've noticed that sometimes all network connections out of the country gets blocked. With syncthing, there are relays within China that can be used which may be in less restrictive provinces.

Kind of a best case, worst case scenario thing such that I can switch between as necessary. WireGuard best case, Xray-core fallback, syncthing worst case
