Verily, they did make support for the Internet of Things.
As always, brilliant writing. For instance:
- “But there was also the Youth Faction, who were indeed very young, some being barely in their mid-forties.”
- “Ask a Delphic question, get a Delphic answer” –

Mikrotik have statistics and way more features. Of the not so good features on the TP-LINK ER-5120 multi-WAN router (none of which are mentioned in their documentation), the worst 2 are:

The CCR1009 will always be faster, even passively cooled: Source: RB3011 Fan Notice compared to CCR 1009 – MikroTik RouterOS.

Heeft iemand van jullie ook ervaring met IPv6 van XS4all met een fritzbox? Ik wil namelijk achter deze fritzbox een mikrotik plaaten en IPv6 door routeert.

First corkboard production server by Google in 1998
Remember the image on the right? It was the first “corkboard” production server Google used in 1998 (it’s a museum piece now).
From there they were using commodity-class x86 server computers running customized versions of Linux for a “long” time which around 2005 even got their own 12V battery as UPS inside the machine and running 1160 machines in a 1AAA shipping container.
Later whey started using a mix of CPU and GPU increasing the performance per watt and recently went from 12V to 48V and even contributed 48V DC Data Center Rack to Open Compute.
In the mean time, Tensor Flow and AI got even more important for Google and during the Google I/O 2016 keynote, they revealed yet another step: TPU chips especially made for TensorFlow providing even better performance per watt for machine learning than GPU. The TPUs are not FPGAs (popular for instance when mining BitCoins), but ASICs that perform orders of magnitude better.
So in about 18 years, Google moved from cleverly assembled commodity hardware to highly specialised custom chips.
Exciting times are ahead of us. I’m really looking forward to the next steps.

I bumped into a disk full issue again because of the btrfs/snapper combination in openSuSE and df basically lying about the disk space, so I w rote this Nice diskinfo alias showing du, df, btrfs, parted, lsblk.
You can combine this with A bash script to btrfs snapshot details like disk sizes (requires btrfs quota to be enabled) to find out which snapper snapshots take up a truckload of space and might be safely removed.
