Since #ChatGPT came out in 2022, the whole of the #IT industry, and indeed #CS academia too, had gone topsy-turvy.

These days, people are trying to use the #LLM for every problem large and small, even ones that could be solved using well known, traditional mathematical methods. Worse, they are now tossing problems they have never heard of and, hence, do not grasp the true nature thereof, into the gaping mouth of LLM, hoping that this miracle machine could make head-or-tail out of something humans were too lazy, or too incompetent, to analyse and understand.

This is the classic case of the hammer seeing nails all around. It is a waste of resources—humans, machines, electricity, space, money, time. In my own career, I have seen this irrational exuberance several times: the LISP rule-based AI boom; the BP connectionist AI boom; the Web boom; the DotCom boom; the Cloud boom; and now the Transformer boom. Up next, the Quantum boom, maybe?

By all means, surf the Wall Street money wave, if that is one’s wont. But intellectuals must always strive to observe the patterns that repeat, analyse abstractly, synthesise concretely, not succumb to the hammer-nail myopia, and above all never abdicate the duty to #think.

“What has been will be again, what has been done will be done again; there is nothing new under the sun.”

ᚠᚢᚦᚨᚱᚲ
#Futhark
#programming language:

• Escaped in 2017 from University of Copenhagen #DIKU, the #CS research group founded by Naur himself
• A member of Milner ML family of functional languages
• Pure functional—like Miranda, Haskell, Elm, etc.—without objects, obviously
• Far more sensible functor (module) syntax than SML and OCaml
• Far cleaner appearance than SML's half-century-old syntax
• Automatic exploitation of GPU-borne parallelism via CUDA or OpenCL

As a life-long fan of Milner's ML, Futhark is a far more comfortable couch upon which to lounge, for me, than the current crop of popular languages that pander to #AI, like R, Python, Julia, Mojo, etc.

💕 Futhark 💕
— modernity without mania
— performance without penance
— maturity without mouldiness
— pedigree without pomposity

Hầu hết công ty SaaS chi 5-7% ARR cho CS, trong khi hàng đầu chi 12-15%, giúp giảm bỏ sót và tăng NRR. CS không chỉ là chi phí hỗ trợ mà là động lực tăng trưởng. Chi phí hợp lý có thể cải thiện LTV lên 50% thay vì chỉ dựa vào marketing. Đánh giá CS như dự án đầu tư với NPV/IRR. #SaaS #CustomerSuccess #CS #DoanhNghiep #LTV #TăngTrưởng

Can anyone recommend me some (online available ;) ) CS textbook that explains Elias-Fano encoding (and SELECT queries on it specifically) in a readable manner?

The original papers are annoying and my advisor just told me "it's popular enough that you can just ask your favourite LLM about it" and hell no

The advent of new functional verified #HDL toolchains and the recent mushrooming of low cost #FPGA development boards might well encourage #EE, #CE, and #CS students to explore CPU architectures that are not von Neumann but are specifically designed to evaluate (not execute, no no no😀) programmes implemented in #FP languages.

Perhaps that might stimulate the resurgence of purpose built, semantically proximate CPUs akin to Knight’s LISP Machine architecture.

The graph reduction based G Machine evaluator could be a good starting point.
