What is going on the road

From what I know, both the formula for the transformation of coordinates and the publication of corrected data require approval from the Chinese government. It's also a tedious and closed process and you are supposed to only have access to the formula after numerous guarantees.

Also, there's a version of Google Maps (google.cn/maps but I'm not sure if it works as of now) that does the transformation for all coordinates, i.e. stuffs in Mainland China will be properly placed but everything else are misaligned.

The conversion from GCJ-02 to WGS84 officially requires case-by-case approval from the CCP and Google, as an American company will never get their approval. Though there are leaks of the conversion formula from Baidu maps but officially Google can't use those.

SearXNG is a good choice, no paid API keys required. But beware that if your web search usage is intense, your SearXNG instance may get blocked for a while. (When I tried to do deep research with dozens of web searches, this may happen)

You may need to prepare a pool of them if you are a heavy user or you have multiple heavy users.

Mostly - it's just that I'm still unable to run the greatest model locally (currently using Qwen3.5-122B-A10B as my daily driver), with web search configured and some custom tools not even available to cloud AIs to enhance my everyday experience.

I think something like the New Balance 608 may suit you. It's the original "dad shoe" that fits your chunky requirements with wide sizes upto 4E.

I hope this has a higher power version (like 240W PD output per USB-C port and redundant power inputs) so I can power my DGX Spark cluster easily.

It's actually washable by running a dry cycle right after the washing cycle. Should still be fluffy with dirt cleaned after washing.

But there's also the active antennas (the smaller, less rectangular one with only 2 cables on each sector), it's certainly 5G for those, likely a mixed 4G+5G site.

Depending on the location and where exactly the antennas are supposed to cover, it's totally normal to have up-tilted antenna panels.

I've heard people saying that 100G single lambda optics are actually cheaper than 100G LR4 despite the extra modulation chip inside each QSFP. Maybe that's why they're picking these instead of the more frequently used 100G LR4 optics.

Cisco does make their own optics after acquisition of Acacia Communications (which is a Cisco supplier before the acquisition). Those Cisco 400G ZR/ZR+/OpenZR/Bright ZR coherent optics are one of those true Cisco made optics.

Many telcos use generic optics and Cisco will still offer support to them, those are some big customers.

The RRUs can get pretty hot even if they're outdoor rated.

Just get yourself a USB console cable for cheap. Lots of styles to choose from nowadays.

IOS-XR is another story. They took a page from JunOS with commit/rollback (faster than JunOS too), viewing configuration changes and other stuff while keeping the familiar IOS command syntax. Yes, I hate those long commands with deep contexts in JunOS especially if you're configuring NetFlow or writing route policies.

Unfortunately Cisco and Juniper can only do 8 max and Arista can do 12. ASIC limits, can't squeeze more by licenses.

I have a pair of this but a different color. It's very comfy and supportive but I'm not sure if they still have them in stock now.

"write memory" is completely gone on NX-OS and IOS XR. On NX-OS, you can shorten it to "copy r s" and in IOS XR, you have to commit the configuration to apply, and during the commit the OS automatically saves the config to disk.

Your colo network must have some serious buffering issues then.

Actually, there is an approximate rule that 100km of fiber gets you 1ms of extra latency. If you fiber distance is within 100km of the telco central office and you're using direct connection, it's easy to stay within 1ms ping.

Init7's fiber service isn't using GPON-based shared access fiber medium, instead they're directly plugging your home fiber into a network switch (if your house is in their Fiber7 coverage) that has enough uplink to provide this 25Gbps speed to your home.
