How would you encode a bencode where the list doesn’t end in a list ? Or is that the purpose of the letter ‘e’ ?

I think reading some Roger Schank's books on different kinds of memories like episodic memory this might be useful too:

Memory Organisation Packets might also deal with issues encountered.

How long from Salesguy to Cashguy ?

I know that for hospitals it is a minimum of 18 months assuming no large purchasing process like RFPs or RFQs. Personally I am surprised when it takes less than 3 years

whitten··on The weirdest QNX bug I've encountered (2021)
iOS isn't open source. Is Android by Google enough open source ? Or are they not the two standards you are thinking about ?

Weren't Blackberry phones almost a requirement for USA government computers ?
whitten··on After 6 years, I'm over GraphQL
Do you think FHIR is acceptable?

It feels like a cross between JSON and HL7 to me.

whitten··on Asqi: A codebase explorer designed to help navigate and understand Git projects
I’m wondering what computer language analysis tools are necessary to make this work for another language. The OG page supplies this info

    Supported languages
    -------------------
    Asqi can provide file-level indexing for everything, 
    and it provides semantic indexing for:

    + C/C++
    + Java
    + Go
    + Rust
    + JavaScript/TypeScript
    + Python
whitten··on They thought they were joining an accelerator – instead they lost their startups
Yes. There is a lot of money to be made in VC. Look at "exit strategy" for more info.
whitten··on Hackers Broke into Change Healthcare's Systems 9 Days Before Cyberattack
One compromised account that had been granted wide reaching authority was then used to control one third of health care applications in this country ?

This sounds like an economic collapse similar to an ecological collapse due to a single genetic monoculture.

whitten··on GOTO (2000)
Does this mean that compilers have given up on processing GOTO if it is written directly by a person, but are fine in analyzing code generated in Intermediate code from GOTO-less code ?

That sounds bad. Is it on any old shareware sites ?
whitten··on (How to Write a (Lisp) Interpreter (In Python)) (2010)
Really?

I would assume any assembly language is worse to program than C

whitten··on Tal is the programming language for the Uxn virtual machine (2021)
Using a stack as input and a stack as output reminds me of the POP-11 language.

A high level value stack available as an input is a truly different way to code.

See other Hacker News articles https://hn.algolia.com/?q=pop-11

whitten··on The hunt for the missing data type
Can you point to where I can learn more about this ? E.G. an example and explanation exists for hyper link embedding ?

I am especially interested in syntax suitable to be used in creating something to input into https://www.viz-js.com and creation of SVGs with embedded hyperlinks.

whitten··on How and why we ripped our open source product apart for a full rebuild
declaration based routing is an intriguing idea.

Does this include a dynamic route map ?

How do you handle path finding in the routes ?

Do you create spanning trees over the routes ?

How do you manage the complexities of adding certain behaviors to particular waypoints ?

whitten··on Rice scientists pull off quantum coup
This is an interesting material science result as it shows the power of an interaction that could be exploited in the future.

Rice University is also where a lot of graphene research occurs.

With some of the current clever innovations in crystallography combining the three dimensional and two dimensional materials, I expect a progression to logic gates and Single Instruction Multiple Data Paths to be a new way to leverage older approaches.

I don’t see that quantum computing will be an easy future direction currently but Rice scientists have surprised me in the past.

whitten··on Solving SAT via Positive Supercompilation
As I recall, memorization usually involves associating the results of calling a pure function with the particular input values so the computation of the function is reduced to a lookup operation.

The calculation of the pure function is still used for any other combination of input values.

Supercompilation looks at the unevaluated symbolic recursive code and replaces the code in some cases with simpler, specialized code tuned to the actual input values, so does a memoizing not only of the result, but the code used to calculate the function to begin with.

whitten··on Classic RuneScape Fonts for Fun
The Font used in RuneScape Classic is a bitmap variant of Arial without anti-aliasing. The game uses bold variants of font sizes 12, 13, 14, 16, 20 and 24, as well as regular variants for sizes 11 and 12. For most of the game interface, size 12 bold Arial is used. However, for certain components that need to be small and unassuming, such as the chat tabs, size 11 regular Arial is used instead.
whitten··on DJGPP
Conceptually this seems to be the opposite of wine. It allows programs written for Linux to run under Microsoft Windows. Wine allows Windows programs to run under Linux.

Is there any way to use the synergy between them to make them work better ?

whitten··on Abykus – A free spreadsheet application for windows
On the page http://www.abykus.com/screenshots.htm there is a link using the text “planner” that refers to a page http://www.abykus.com/retirement.htm that apparently doesn’t exist.

This makes me sad since I wanted the Amortization Schedule spreadsheet that is said to be available on that page.

whitten··on Lego Mechanical Computer
Problem with page. The text “rod logic” connects to a page that doesn’t exist : https://sites.google.com/site/santiagoontanonvillar/Home/leg...

Does anyone know where the page moved ?

Is the page : https://anthony-zhang.me/blog/rod-logic/ A good substitute ?

Or is the page : https://keshav.is/building/lego-logic-gates/ A good substitute ?

Shakna, what were you originally planning ?

Thanks in advance.

Could you elaborate ? What is dang ?

This history of a bug fix or bug request shows again the need for more intelligent indexing for both bugs and for software, especially when the program is an editor or a browser.

I would expect that SOLR could actually do the indexing but knowing what needs to be indexed is still a real issue. I think an ontology of software that includes more WHY particular things are done in programs or data needs to be included in current Software Engineering practices.
