Explaining how computers really work—from logic gates, CPUs, memory, C Language, and Linux to RISC-V, ARM, x86, AI, and large language models.

BREAKING: A federal court filing reportedly identifies Rep. Ilhan Omar as “Ilhan Nur Said Elmi,” also known as “Ilhan Abdullahi Omar,” raising fresh questions about her immigration records.

The public deserves a clear explanation. Why was that name used, and what do the underlying documents show?

A different name alone does not prove fraud—or establish that her former husband was her brother, an allegation Omar has denied.

Release the evidence. Investigate thoroughly. If wrongdoing is proven, hold her accountable under the law. No special treatment for anyone in Congress.

Google Cloud is adding OpenAI models, and usage can draw down existing cloud commitments.

I think that explains more than another leaderboard. Google can lose the model choice and still keep the customer’s spending inside Google.

Claude Duet can message me before I ask. I think the real test is whether I get fewer interruptions overall.

If I still check my inbox because I don’t trust what it left out, I’ve gained another inbox.

If this PHP vulnerability allows remote code execution, can’t we just use it to patch every vulnerable server?

It’s not an exploit. It’s an unsolicited update service.

[Gate and Kernel @insidecomput]

Organizations running PHP-based systems should prepare to apply security updates addressing two reported critical vulnerabilities.

Depending on the affected versions and configurations, exploitation could expose server files or databases.

Identify affected deployments and apply the relevant patches as soon as they become available.

If patching must be delayed, apply verified mitigations or temporarily take affected services offline until the risk is addressed.

I like longer AI prompt caching. I also see a switching cost:

the same context can be cheap with my current provider and expensive to process from scratch elsewhere.

Exporting a chat is one thing. Exporting its economics is another.

I don’t want an AI assistant that makes me rehearse a question so I won’t look stupid.

The point was to ask what I’d be embarrassed to ask a person.

A tool that makes me hide my confusion gets worse input, however smart it is.

I’m more impressed by AI helping rebuild a 2009 Bitcoin executable byte for byte than by another app demo. Open source lets me inspect the recipe.

A reproducible build lets me check that the meal I was served actually came from it.

Our sentence contains several tokens, and each token has a vector. Placing those vectors into rows produces a matrix.
