Machine Learning, Kolmogorov Complexity, and Squishy Bunnies Computer Science, Machine Learning, Programming, Art, Mathematics, Philosophy, and Short Fiction

Fun thing of the moment: Kolmogorov Complexity! I came across a great, accessible write up today and wanted to share. Does anyone else use K-complexity or measures of entropy in their work?

You can also forward your ssh-agent through the ssh connections that you make so that you donโ€™t need to copy your private key off of your laptop

Does anyone else agree that certain Linux commands make great insults?

Take a look at ssh-agent. You do need to enter your passphrase one time to โ€˜unlockโ€™ your ssh key but then future connections are password less.

Please please please set passphrases on private ssh keys. Any administrator of a system that your ssh key resides on can use your private key.

Practically, Iโ€™ve used a shared IB network to pivot between systems that I did not have logical access to, but that did have a shared Lustre filesystem.

13.02.2025 13:04 โ€” ๐Ÿ‘ 0    ๐Ÿ” 0    ๐Ÿ’ฌ 0    ๐Ÿ“Œ 0

Solid question. I consider IB to be a layer 2 network without many of the segmentation tools that IP routing gets you. Once you set up RDMA, you also lose most abilities to monitor and control traffic over that channel

No matter how good you think you are, you gotta be coachable if you want to get better.

NIST Special Publication (SP) 800-223, High-Performance Computing Security: Architecture, Threat Analysis, and Security Posture Security is essential component of high-performance computing (HPC). HPC systems often differ based on the evolution of their system designs, the applications they run, and the missions they support. ...

How about a fun #HPC #CyberSecurity relevant discussion? We came out with some guidance mid 2024 for #riskmanagement folks that I encourage everyone to read. csrc.nist.gov/pubs/sp/800/...

Oh thatโ€™s neat, I didnโ€™t realize that. Iโ€™m assuming that there is negligible hypervisor overhead?

11.02.2025 15:04 โ€” ๐Ÿ‘ 0    ๐Ÿ” 0    ๐Ÿ’ฌ 1    ๐Ÿ“Œ 0

Yeah. I hear that, especially for scientific codes. For things like drivers and system services I think memory safety is worth the hassle.

They may be geeky, but theyโ€™re a crucial if not very visible part to our day to day lives. Weather forecasting is a big one as well as industrial uses like development of complicated stuff like more cost efficient jet engines and new medicines.

I need opinions. How bad is disabling โ€˜panic on oopsโ€™ in the Linux kernel? I mean, how bad could it be?

Is that just the memory safeness talking or are there other issues with rust that you could elaborate on?

On the other hand if I am currently paying people for tasks that a model can perform easily, switching to AI driven work makes things less even

Interesting question. It probably does in many ways. Give me a good offline model and Iโ€™ve got a mini Wikipedia that I can take anywhere for example.
