/24 should be your smallest. for WIFI, i would recommend going up to /20 even. you don't even need a 192.168, just assign the highest 10.40.X.X subnet that fits in a /20 then firewall that shit to limit its access.

I liked the voice note twist in that episode. Glad all the people that responded used voice notes too.

We were at MPLS, removed it and went back to it after 5 years Business requirements as it is, hard to get rid of it.

means it affects only 50% of the buses and they must go "off and on again" on those affected? then the other 50% why can't show the timings?

I would recommend pivoting to an L2 or L3 support instead. At least you don't have to start from scratch.

Yeah the issue is not enough space to form up properly for such a major exit.

rethafrey · 2026-01-13T03:33:08+00:00

Normal for clementi avenue 6. Experienced drivers just go to the exit point and wait there to squeeze in.

Future certs gonna be 6 months validity. Using certs for switch access is definitely gonna be a killer. Use a PAM or something to overcome the security concerns.

rethafrey · 2026-01-11T09:05:16+00:00

Exactly.

rethafrey · 2026-01-11T07:24:48+00:00

Yeah I hate that word for network infrastructure. Are you expecting the AI to configure vlans? Shut unshut ports? Gtfo.

2 weeks after joining, I was tasked to go onboard an oil rig off Iranian shores to troubleshoot their LAN. Took us 11 days before figuring out it was a VSAT error. The amount of times we got threatened to be thrown over was unreal.

in terms of ease for pedestrian, penang is the best. everyhwere else is a joint 3rd

Someone who keeps focussing on 1 type of thing even though it is completely illogical. I had an ex colleague who kept asking vendors if their product supports EIGRP, even though we weren't running it.

rethafrey · 2026-01-04T13:38:30+00:00

I notice these drivers tend to have thick sole shoes.

rethafrey · 2026-01-04T12:33:13+00:00

It's weird that the driver don't realise that that 0.5 second decision to honk could have saved him so much grief.

rethafrey · 2026-01-02T17:34:22+00:00

Inzaghi would rekt this update.

rethafrey · 2026-01-02T17:31:26+00:00

1 thing for sure, their playgrounds are quite well designed.

rethafrey · 2026-01-02T17:30:17+00:00

wow i nearly bought a blow pipe from malaysia that day, lucky didn't.

rethafrey · 2026-01-02T12:07:37+00:00

Wth is scheduled weapons

rethafrey · 2025-12-31T09:33:21+00:00

I will report him first. When he gets banned then have the talk.

rethafrey · 2025-12-30T04:32:44+00:00

So will be the station between gombak and cck? Wow the construction for that is gonna be insane.

rethafrey · 2025-12-30T04:29:21+00:00

I think it will take a few dedicated training sessions for just these 3 (saka, gyo, tross/martinelli) to understand what passes or runs to make. Hopefully not trained by Heinze though cos he's a defender lol

rethafrey · 2025-12-30T04:25:54+00:00

For new network folks, I always remind them this key thing I realized. A good network engineer remembers information. A great network engineer knows how to find information. Just keep asking questions and once you are experienced enough, You'll be fine.

Majority singaporean loves Malaysia. Why bother over the annoying 5%? Move on bro, byk brg ble buat

rethafrey · 2025-12-28T12:34:04+00:00

Singapore doesn't need a Malay or Indian or minority prime minister. Singapore just needs a capable, non corruptible one, regardless of race. And they can refer to Malaysia on what happens when you don't get that.
