Does anyone have an electronic copy of the CMU tech report of Michael Wayne Young Ph.D. thesis
"Exporting a User Interface to Memory Management from a Communication-Oriented Operating System"?

This is CMU technical report CMU-CS-89-202. The CMU tech report server has no entries for 1989...

I have an offspring who graduated with the May 2024 class (but was actually done in Dec 2023) who needs a #JobOpportunity

He has a #CS degree *and* #Linguistics from a well-known #NorthEast school. He had a great co-op at a prestigious research institution. He worked as a TA to the #software students and was prominent in the linguistics lab, contributing to a paper he helped present at a national conference

He doesn't know I'm posting this, but I believe he's looking for a software #engineering position, remote or in the #NorthEast #US. If there is related linguistics work so much the better.

#Buffalo has a very supportive community for #trans people, and it is also 40 minutes to Toronto, Canada.

The University of Buffalo is hiring staff for Comp Sci and Eng, which is growing by leaps and bounds. If these two things intersect for you, consider applying.

Disclaimer: No, I don't actually have anything to do with UB, but I do live in the community, and the department got a new building of their own. #GetFediHired #CS #CompSci

alphaXiv is a very useful search engine for arXiv papers. One of its nice features is that for many papers, section headings are shown for the paper just below the abstract. If you click on the section heading, it will display some text from the paper relevant to that section of the paper.
It also usually shows a screenshot of the first page of the paper. It also shows discussion related to the paper.

I think it would be a good time to reinstantiate the mirror network for the # arXiv. It’s an essential piece of the global research community in math, physics, computer-science and adjacent fields. Under the current circumstances it should not only be hosted in the US.

🦾 State Space Models are Strong Text Rerankers

arxiv.org/abs/2412.14354

arXiv.orgState Space Models are Strong Text RerankersTransformers dominate NLP and IR; but their inference inefficiencies and challenges in extrapolating to longer contexts have sparked interest in alternative model architectures. Among these, state space models (SSMs) like Mamba offer promising advantages, particularly $O(1)$ time complexity in inference. Despite their potential, SSMs' effectiveness at text reranking -- a task requiring fine-grained query-document interaction and long-context understanding -- remains underexplored. This study benchmarks SSM-based architectures (specifically, Mamba-1 and Mamba-2) against transformer-based models across various scales, architectures, and pre-training objectives, focusing on performance and efficiency in text reranking tasks. We find that (1) Mamba architectures achieve competitive text ranking performance, comparable to transformer-based models of similar size; (2) they are less efficient in training and inference compared to transformers with flash attention; and (3) Mamba-2 outperforms Mamba-1 in both performance and efficiency. These results underscore the potential of state space models as a transformer alternative and highlight areas for improvement in future IR applications.

Hearing about a young hacker whose being extorted by the University of Washington, not cool UW.

The student claims they built an app to help kids get the course schedules they want, a hack as old as time, and the university decided to expel him until he ports his app to the university's internal systems.

This would be unpaid labor.

Until then his class registration is on hold and he can't register or attend his last few classes. 🥴

Welp, looks I might be getting expelled from the University of Washington. As many of you know, last quarter I built an initial version of HuskySwap for a class project. It was a simple app designed to help students find partners to trade spots in critical classes after they filled up. I’m sure other people have pursued this kind of thing before, but there’s no go-to solution at UW and I wanted to contribute something cool for everyone. At first it was a fun project to catch up to the latest versions of .NET and Angular with some practice implementing features around database abstraction, real-time chat, and the full stack challenges associated with things like role-based permissions. I was probably going to build it anyway, so it was great that I could actually get course credit for CSE 403. I was really proud of the MVP and excited that the people I demoed it for actually wanted to use it. So I set aside some time in my winter quarter schedule to start hardening it so I could launch ahead of spring quarter registration. Then I came across the swagger docs for integrating with the registration system. The site says: “The Student Web Service gives your application access to information in the Student database such as course data, registration data, section data, person data, and term data (general academic data).”
I reached out to request an access token. I wasn’t too ambitious up front; all I wanted was read-only access to automate the course catalog import instead of having to manually enter every class. But if things went well it would be awesome to automate the process further or even find other gaps I could fill to improve the community experience. Several hours later I received an unambiguous response: a “Notice of Violation of Registration Tampering Abuse Policy”. I was instructed to take down my demo site (and its handful of fake demo classes) or else they would begin the process that would culminate with my expulsion. I had originally reached out hoping to make the school experience better for everyone and they immediately went nuclear. I’m not too worried about the threat since taking down the demo site is no big deal. But I’m a little heartbroken to see how the school views me. I thought they’d be excited about what I was pursuing—or at least that I was pursuing anything—but they’d rather have me simply leave. I’m scheduled to graduate in a few months and am eager to move on to projects that don’t need to be cleared with the UW Registrar. If you know of anyone looking for a full-time software engineer with a knack for getting the attention of senior leadership, please send them my way! I can start full-time in June.

Anyone who has cleaned a dwelling space knows that cleaning the cleaning machines—vacuum cleaner, washing machine, dishwasher, etc.—is far harder than using those cleaning machines to clean the dwelling space.

Likewise, in #computing, implementing the CPU, the compiler, the OS, etc.—meta #programming, as it were—is orders of magnitude more difficult than writing the first-order application programmes.

All undergrad #CS students should explore those cracks and creases of computing, as early as maybe in their studies, for these hard subjects can reprogram their young minds for the better, thereby making their future careers easier.

@peter

The only major question I would ask at a programmer interview is "Tell me about your personal software project".

If you study #CS and don't have a personal project(s), then yes.
Become a real estate person.

It's like studying to be a doctor, with no passion to heal people.
If you are just in it for the money, you will not be as good as the folks who are in it for the passion.

My first advice to young folks who study CS/IT is to "Make your own project"

The younger #cs peeps in the fam took a brute-force approach (including the #linguistics double-major for some reason). With a string this long, that's going to take FOREVER.

I've felt all along that just thinking about how English works and looking at word lengths should almost solve this problem.

For instance, the string starts with

A abcdd dddeeee E...

Assuming capitalization was preserved, that E has to be I.

There are other grammar constraints. The 5- and 7- letter words can't be both nouns, for instance. They most likely are

I <adverb> <adjective> I...

or

A <adjective> <noun> I....

Looking at some English corpora datasets, it looks like my best bets are

I never thought I...

or

[this example left blank bc the website I need is down for maintenance]

The next step is probably to look at

...oooo prss sstt tttt...

Four 4-letter words in a row. That has to have some verbs + helpers in it. Like "have also gone" or "have been then". Gonna use #google ngram 4-grams to figure out what's most likely.

More possibilities may occur after this or maybe brute force from those seeds will work better.

Apparently the 3 Big #CS #Math #Nerds in the kids' group chat were talking about one-way problems (like hashes, but more generally). The #theater / #writer kid dropped a string into their midst:

A abcdd dddeeee E eeefg hhhhh iiiiiiii kll lmm mm mnnnnn ooo oooo prss
sstt tttt tuuuvvw wwwyy

We are pretty sure this is an alphabetized sentence that's preserved the word lengths. The #puzzle creator has told us nothing.

One of us wrote #rust #code that exhaustively solves but will obviously take much longer than the universe's age to complete.

After some discussion, I wrote some #python code with some heuristics and manual pruning (e.g. I doubt "consumer" is one of the words). I stopped it at 18GB of partial answers while still only in the a's

I think it's time for a more #crypto approach...
