New comment by panosv in "The ping-verse: a deep dive into 14 ping-type utilities across OSI layers"

Everyone knows ping. But over the decades, the networking community has quietly built an entire family of specialized variants — each solving a problem that standard ICMP couldn't. A few examples of why you'd reach for something else:

tcping — when firewalls eat your ICMP and you need to test port availability

arping — L2 diagnostics and duplicate IP detection, no IP stack needed

fping — scan a /24 in seconds, all hosts in parallel

OWAMP — when you actually need one-way latency, not just RTT

dnsping — when the slowness lives in your resolver, not the network

I put together a comparison table of the most useful ones, across protocol, OSI layer, platform, multi-host support, and root requirements. The OSI layer column alone tells you a lot — if you're reaching for ping to debug something that lives at L4 or L7, you're probably using the wrong tool.

What about Google? Anyone has any insights on their unit economics since they own the models and the infrastructure (which is also custom TPUs)? Are they doing better or are they in the same money losing business?

Can someone recommend a dongle that actually works? I’ve tried a few and they are highly unreliable or stop working after a few months.

New comment by panosv in "IBM scientists demonstrate 10x faster large-scale machine learning using GPUs"

panosv — Thu, 07 Dec 2017 14:37:40 +0000

That's the point. On the GPU side they use all the 5000+ cores to parallelize the algorithm (they use the hardware to its full potential). On the CPU side they use just one core (at least there is no mention around the cores used on the CPU). It's like saying a Camry beat a Ferrari in maximum speed, but you don't mention that the Ferrari was only in the first gear for that specific race.

How about if you did the same on 8 or 16 core CPU that can have much more than 16 GB of memory and is not as expensive to move data around its own memory?
