@arisetyo_v2 Sendiri bro, gw ada 1 mesin n 2 vm buat claude code. Ini dari 1 mesin yg gw pake daily. Gw pake skill ini n selalu pas brainstorming mode ga percaya asumsi jadi liat fakta di codebase melulu:

@boardyai Meet new people by meeting yourself first then connect. Connect with potential bandmates, founders, date and even karaoke is on the table.

Building something scratch in 2026 is so different. Changes how a startup is built. I build for me to solve my problems, if it resonates with other people then cool.

Going all in on being as opinionated as i can is the moat. UX is to my taste and especially the codebase.

@Th3RealSocrates Warm storage for now. I have a large array that doesn't justify replacing it just yet. As for the M4, it's great for single threaded heavy computing which is most of my use cases.

I left my home lab back in Dubai. It's still on, I still remote into them but latency is too high. So I'm gonna home lab minimally back home in Jakarta with 2 devices. First is an Unraid server on an old Intel i3 6100 and the other one is a Mac Mini M4.

The first hardware used for @UnraidOfficial. Wiped the dusts, got some SSDs in and it's up and running again.

I use it everyday, it has replaced warp for me.

Immediately felt at home because it loaded almost instantly and it doesn't get in the way. I just read this:

I feel so dumb, I did not RTFM and I looked for alternatives because I wanted tabs on the left. But having the tabs on the bottom left and switching with Cmd + 1-9 is much less in the way of screen real estate which I think is perfect.

Thank you!

Coding in 2026, a foldable makes total sense.

My son asked me to help him create a game in Roblox. This is similar to me decades ago trying out Digger the first time and wanting to understand how to build it.

Nowadays we have Claude Code and skills relevant to the tasks. So that's what I wanna do first. Then I'm going to transfer the knowledge.

[Batista Harahap @tista]

And it starts.

I hate the ads though. This is even though ads are supposedly resolving into a black hole.

Have been using Apple TV devices since 2018, but I forgot to pack one when flying back to Indonesia. Decided to try out a Google TV box and bought a Xiaomi box. Damn it's different and good.

Best feature: voice commands.

"Turn off my tv" ==> Most used.

The single most felt improvement is latency.

When i hooked up the RJ45 backbone the first time, the latency was very minimal. Over time the cable degrades and i notice this because sometimes the link negotiated 100 Mbps link speed after a while.

Replacing RJ45 with a fiber optic cable restored that latency win and pings are stable below 1 ms to the gateway. Before it fluctuates between under or over 1 ms.

I know the ms doesn’t look much but the ping and the downgrade in link speed are indicators of bad cabling. It lasted about 6 years do in BSD weather so it was great until it isn’t.

The first floor plugged directly to a Unifi Cloud Gateway Fiber SFP+ port. The third floor still uses a media converter. A pair of 10 gig transceivers + an SFP+ switch upstairs would change that. Direct optical connections would be cool between the floors.

Working on a little adventure outside of my comfort zone. I want to connect the first and third floors of my house with fiber optic.

I had it connected through RJ45 but it's a risk, lightning can strike to blow up my networking equipments. I don't have that kind of risk with fiber optic cables. The wires are routed through the facade of the house.

I bought these 2 to make this happen:

- https://t.co/ntLwMAbQZS

The media converter is a cheap and temporary solution for now to replace the RJ45 backbone. Later if and when I wanna do 10 Gbps, that's a transceiver and switch upgrade. But that's later.

Gonna post here later for more build stories and pics.

Next up is connecting the UCG Fiber in Jakarta to my UDM Pro in Dubai. Unifi has a Site Magic feature BUT it only works if one of the node has a public IP. So this is ruled out, none of the gateways has public IPs.

As always, I have an @UnraidOfficial install in both locations. Tailscale is native now on Unraid and already connected. Question becomes, how can my Jakarta LAN subnet reaches the Dubai LAN subnet?

First, set up Unraid.

```
$ vim /boot/config/go
# Tailscale gateway
sysctl -w net.ipv4.ip_forward=1
sysctl -w net.ipv6.conf.all.forwarding=1
iptables -t nat -A POSTROUTING -o tailscale1 -d 10.7.7.0/24 -j MASQUERADE
```

Actually run the 3 commands afterwards.

The I set up a static route in the UCG Fiber using Policy Based Routing. Now it's working!
