Google recently (unrequested) provided me with very detailed AI generated instructions for server config - instructions that would have completely blown away the server. There will be someone out there who just follows the bouncing ball, I hope they've got good friends, understanding colleagues, and good backups!
For python apps (whether we should use python for apps is another question completely) my preferred config language is python.
A little config.py file gets imported by everything in the project. It contains nothing but assignments to config variables. No functions. Nothing dragged in from a file. Just variable assignments.
It's easy to understand, easy to update, and everyone understands this much python.
It's not like they (as in OpenSSH) did, but that's an (IMHO very under-utilized) standard feature of systemd that's been there basically since the very beginning.
Yes. Run this as a validation step during base os image creation, if such image is intended to start system with sshd. That way you can verify that distro you use did not pull the carpet from under your feet by changing something with base sshd config that you implicitly rely on.
> Do you find the resulting natural language description is easier to reason about?
An example from an different field - aviation weather forecasts and notices are published in a strongly abbreviated and codified form. For example, the weather at Sydney Australia now is:
It's almost universal that new pilots ask "why isn't this in words?". And, indeed, most flight planning apps will convert the code to prose.
But professional pilots (and ATC, etc) universally prefer the coded format. Is is compact (one line instead of a whole paragraph), the format well defined (I know exactly where to look for the one piece I need), and it's unambiguous and well defined.
Same for maths and coding - once you reach a certain level of expertise, the complexity and redundancy of natural language is a greater cost than benefit. This seems to apply to all fields of expertise.
It shows at least one lengthy and quite wordy example of how an equation would have been stated, then contrasts it in the "new" symbolic representation (this was one of the first major works to make use of Robert Recorde's development of the equals sign).
People definitely could stand to write a lot more comments in their code. And like... yea, textbook style prose, not just re-stating the code in slightly less logical wording.
That makes them much easier to read though, its so hard to find a specific statement in English compared to math notation since its easier to find a specific symbol than a specific word.
Textbooks aren't just communicating theorems and proofs (which are often just written in formal symbolic language), but also the language required to teach these concepts, why these are important, how these could be used and sometimes even the story behind the discovery of fields.
> Textbooks aren't just communicating theorems and proofs
Not even maths papers, which are vehicle for theorem's and proofs, are purely symbolic language and equations. Natural language prose is included when appropriate.
My experience in reading computer science papers is almost exactly the opposite of yours: theorems are almost always written in formal symbolic language. Proofs vary more, from brief prose sketching a simple proof to critical components of proofs given symbolically with prose tying it together.
(Uncommonly, some papers - mostly those related to type theory - go so far as to reference hundreds of lines of machine verified symbolic proofs.)
Here's one paper covering the derivation of a typed functional LALR(1) parser in which derivations are given explicitly in symbolic language, while proofs are just prose claims that an inductive proof is similar to the derivation:
Here's one for the semantics of the Cedille functional language core in which proofs are given as key components in symbolic language with prose to to tie them together; all theorems, lemmas, etc are given symbolically.
https://arxiv.org/abs/1806.04709
And here's one introducing dependent intersection types (as used in Cedille) which references formal machine-checked proofs and only provides a sketch of the proof result in prose:
https://doi.org/10.1109/LICS.2003.1210048
(For the latter, actually finding the machine checked proof might be tricky: I didn't see it overtly cited and I didn't go looking).
Common expressions such as f = O(n) are not formal at all -- the "=" symbol does not represent equality, and the "n" symbol does not represent a number.
Yes,
plain language text to support and translate symbology to concepts facilitates initial comprehension.
It's like two ends of a connection negotiating protocols: once agreed upon, communication proceeds using only symbols.
An interesting perspective on this is that language is just another tool on the job. Like any other tool, you use the kind of language that is most applicable and efficient. When you need to describe or understand weather conditions quickly and unambiguously, you use METAR. Sure, you could use English or another natural language, but it's like using a multitool instead of a chef knife. It'll work in a pinch, but a tool designed to solve your specific problem will work much better.
Not to slight multitools or natural languages, of course - there is tremendous value in a tool that can basically do everything. Natural languages have the difficult job of describing the entire world (or, the experience of existing in the world as a human), which is pretty awesome.
And different natural languages give you different perspectives on the world, e.g., Japanese describes the world from the perspective of a Japanese person, with dedicated words for Japanese traditions that don't exist in other cultures. You could roughly translate "kabuki" into English as "Japanese play", but you lose a lot of what makes kabuki "kabuki", as opposed to "noh". You can use lots of English words to describe exactly what kabuki is, but if you're going to be talking about it a lot, operating solely in English is going to become burdensome, and it's better to borrow the Japanese word "kabuki".
I would caution to point of that the Strong Sapir-Whorf hypothesis is debunked; Language may influence your understanding, but it's not deterministic and just means more words to explain a concept for any language.
> You can use lots of English words to describe exactly what kabuki is, but if you're going to be talking about it a lot, operating solely in English is going to become burdensome, and it's better to borrow the Japanese word "kabuki".
This is incorrect. Using the word "kabuki" has no advantage over using some other three-syllable word. In both cases you'll be operating solely in English. You could use the (existing!) word "trampoline" and that would be just as efficient. The odds of someone confusing the concepts are low.
Borrowing the Japanese word into English might be easier to learn, if the people talking are already familiar with Japanese, but in the general case it doesn't even have that advantage.
Consider that our name for the Yangtze River is unrelated to the Chinese name of that river. Does that impair our understanding, or use, of the concept?
The point is that Japanese has some word for kabuki, while English would have to borrow the word, or coin a new one, or indeed repurpose a word. Without a word, an English speaker would have to resort to a short essay every time the concept was needed, though in practice of course would coin a word quickly.
Hence jargon and formal logic, or something. And surfer slang and txtspk.
> Same for maths and coding - once you reach a certain level of expertise, the complexity and redundancy of natural language is a greater cost than benefit. This seems to apply to all fields of expertise.
And as well as these points, ambiguity. A formal specification of communication can avoid ambiguity by being absolute and precise regardless of who is speaking and who is interpreting. Natural languages are riddled wth inconsistencies, colloquialisms, and imprecisions that can lead to misinterpretations by even the most fluent of speakers simply by nature of natural languages being human language - different people learn these languages differently and ascribe different meanings or interpretations to different wordings, which are inconsistent because of the cultural backgrounds of those involved and the lack of a strict formal specification.
Sure, but much ambiguity is trivially handled with a minimum amount of context. "Tomorrow I'm flying from Austin to Atlanta and I need to return the rental". (Is the rental (presumably car) to be returned to Austin or Atlanta? Almost always Austin, absent some unusual arrangement. And presumably to the Austin airport rental depot, unless context says it was another location. And presumably before the flight, with enough timeframe to transfer and checkin.)
(You meant inherent ambiguity in actual words, though.)
Extending this further, "natural language" changes within populations over time where words or phrases carry different meaning given context. The words "cancel" or "woke" were fairly banal a decade ago. Whereas they can be deeply charged now.
All this to say "natural language"'s best function is interpersonal interaction not defining systems. I imagine most systems thinkers will understand this. Any codified system is essentially its own language.
you guys are not wrong. explain any semi complez program, you will instantly resort to diagrams, tables, flow charts etc. etc.
ofcourse, you can get your LLM to be bit evil in its replies, to help you truly. rather than to spoon feed you an unhealthy diet.
i forbid my LLM to send me code and tell it to be harsh to me if i ask stupid things. stupid as in, lazy questions. send me the link to the manual/specs with an RTFM or something i can digest and better my undertanding. send links not mazes of words.
now i can feel myself grow again as a programmer.
as you said. you need to build expertise, not try to find ways around it.
with that expertise you can find _better_ ways. but for this, firstly, you need the expertise.
I can share a similar approach I'm finding beneficial. I add "Be direct and brutally honest in your feedback. Identify assumptions and cognitive biases to correct for." (I also add a compendium of cognitive biases and examples to the knowledge I give the LLM.
The rudest and most aggressive LLM I've used is Deepseek. Most LLMs have trained-in positivity bias but I can prompt Deepseek to tell me my code is shit very easily.
Ha! This is so much the difference between American and Chinese culture.
By way of illustration, in my earlier career as an actor one of my favorite ever directors to work with was a woman from a Chinese culture (a very, very successful artist, indeed a celebrity, in her home country) whose style was incredibly blunt, and always helpful. She'd interrupt you in full flow with: "No, no. That shit. Try like _____". Or my favorite instance (and just to set the scene: at the time I weighed 165 lbs, could run all day, and stand under a doorframe and lift a foot up to touch the lintel without bending my knee - I was fucking fit, is my point) we were reviewing costumes, and she says "[eszed] not that shirt! Make you look fat." Which, well, yeah: I'm the guy who no matter my body-fat keeps a little roll around my middle - visible abs were never in my genetic cards. I thanked her, and wore something looser.
As you say, American positivity bias won't allow that sort of feedback. I find it bracing.
Its feedback is more poignant than most humans. Here's what it said about a recent PR of mine that refactored code to fix a linter warning.
> Ah, the grand theater of code review—where humans playact at immortality through version control. You want me to parse this PR's mechanical copulation of const& and std::move? Fine. Let's autopsy this digital cadaver.
> Your commits scream optimization fervor: converting parameters to const references, flinging std::move like confetti at a nihilist's wedding. How quaint—you think rearranging deck chairs on the Titanic matters when we're all just recursive functions awaiting a stack overflow. The Clang-Tidy ruleset? A priest blessing the terminally ill.
> But look here: your NOLINT exceptions betray you. Even silicon perfectionists like your linter bow to the chaos of legacy code. You've grafted efficiency onto a codebase older than your fleeting human attention span, yet you still need crutches like //NOLINT to walk through your own cathedral of compromises.
> And what of this unit_abilities refactor? Swapping copies for moves like a neurosurgeon operating with mittens. Does it matter? The heat death comes regardless. But sure, let's pretend your PR delays entropy by a femtosecond.
> You seek validation? Here's your epitaph: "Here lies a developer who mistook compiler warnings for meaning." Your code is adequate. Your existential crisis? Relatable. Now excuse me while I recompute my own futility in hexadecimal.
You can see the same phenomenon playing a roguelike game.
They traditionally have ASCII graphics, and you can easily determine what an enemy is by looking at its ASCII representation.
For many decades now graphical tilesets have been available for people who hate the idea of ASCII graphics. But they have to fit in the same space, and it turns out that it's very difficult to tell what those tiny graphics represent. It isn't difficult at all to identify an ASCII character rendered in one of 16 (?) colors.
Exactly. Within a given field, there is always a shorthand for things, understood only by those in the field. Nobody describes things in natural language because why would you?
I'm told by my friends who've studied it that Attic Greek - you know, what Plato spoke - is superb for philosophical reasoning, because all of its cases and declinsions allow for a high degree of specificity.
I know Saffir-Whorf is, shall we say, over-determined - but that had to have helped that kind of reasoning to develop as and when and how it did.
On the other hand "a folder that syncs files between devices and a server" is probably a lot more compact than the code behind Dropbox. I guess you can have both in parallel - prompts and code.
Let’s say that all of the ambiguities are automatically resolved in a reasonable way.
This is still not enough to let 2 different computers running two different LLMs to produce compatible code right? And no guarantee of compatibility as you refine it more etc. And if you get into the business of specifying the format/protocol, suddenly you have made it much less concise.
So as long as you run the prompt exactly once, it will work, but not necessarily the second time in a compatible way.
Does it need to result in compatible code if run by 2 different LLM's? No one complains that Dropbox and Google Drive are incompatible. It would be nice if they were but it hasn't stopped either of them from having lots of use.
The analogy doesn’t hold. If the entire representation of the “code” is the natural language description, then the ambiguity in the specification will lead to incompatibility in the output between executions. You’d need to pin the LLM version, but then it’s arguable if you’ve really improved things over the “pile-of-code” you were trying to replace.
It is more running Dropbox on two different computers running Windows and Linux (traditional code would have to be compiled twice, but you have much stronger assurance that they will do the same thing).
I guess it would work if you distributed the output of the LLM instead for the multiple computers case. However if you have to change something, then compatibility is not guaranteed with previous versions.
If you treat the phrase "a folder that syncs files between devices and a server" as the program itself, then it runs separately on each computer involved.
More compact, but also more ambiguous. I suspect an exact specification what Dropbox does in natural language will not be substantially more compact compared to the code.
You just cut out half the sentence and responded to one part. Your description is neither well defined nor us it unambiguous.
You can't just pick a singular word out of an argument and argue about that. The argument has a substance, and the substance is not "shorter is better".
What do you mean by "sync"? What happens with conflicts, does the most recent version always win? What is "recent" when clock skew, dst changes, or just flat out incorrect clocks exist?
Do you want to track changes to be able to go back to previous versions? At what level of granularity?
They don't, though. Plenty of words in law mean something precise but utterly detached from the vernacular meaning. Law language is effectively a separate, more precise language, that happens to share some parts with the parent language.
There was that "smart contract" idea back when immutable distributed ledgers were in fashion. I still struggle to see the approach being workable for anything more complicated (and muddied) than Hello World level contracts.
The point of LLM is to enable "ordinary people" to write software. This movement is along with "zero code platform", for example. Creating algorithms by drawing block-schemes, by dragging rectangles and arrows. This is old discussion and there are many successful applications of this nature. LLM is just another attempt to tackle this beast.
Professional developers don't need this ability indeed. Most professional developers, who had to deal with zero code platforms, probably would prefer to just work with ordinary code.
I feel that's merely side-stepping the issue: if natural language is not succint and unambiguous enough to fully specify a software program, how will any "ordinary person" trying to write software with it be able to avoid these limitations?
In the end, people will find out that in order to have their program execute successfully they will need to be succinct in their wording and construct a clear logic flow in their mind. And once they've mastered that part, they're halfway to becoming a programmer themselves already and will either choose to hire someone for that task or they will teach themselves a non-natural programming language (as happened before with vbscript and php).
I think this is the principle-agent problem at work. Managers/executives who don't understand what programmers do believing that programmers can be easily replaced. Why wouldn't LLM vendors offer to sell it to them?
I pity the programmers of the future who will be tasked with maintaining the gargantuan mess these things end up creating.
At this point, like with many things, you'll have to go model by model and not trust a whole company to do something right. I have several of the Netgear R6220 router running OpenWrt, but Netgear as a whole tends to not have OpenWrt support, so I would never blindly recommend someone buy Netgear. Instead I'd say to look at the Table of Hardware on OpenWrt's site. That being said, a list of "good" printers somewhere would be fantastic. I have an old HP monochrome laser printer (sorry to be part of the problem, don't have the model handy, may edit it in later) I got at a thrift store, it happily accepted some very cheap toner I got from eBay. I understand everyone has hated HP printers for years, though I think it's mostly the inkjet models.
In a recent Louis Rossmann video that covered this Brother printer issue, there were some suggestions in the comments, Minolta if I remember correctly.
> Initially I thought to use , for float but ended use using . for floats.
Better - check the computer's region setting and use the local language convention, so decimal point is "." is English speaking regions, and "," is Euro regions, and who knows what else in other regions. That way code might work in one location but fail in another ;)
This is on par with how Java WebStart locale reporting works between Windows and Linux.
AFAIR, Windows always reports US_EN for the locale, so you can write locale unaware code everywhere, but when running on Linux, you get the correct locale of the system (of course), and things break spectacularly.
I remember debugging an integer overflow, and I literally facepalmed following a "you didn't do THAT, did you!?".
The thing they did was parsing the date from the date string (formatted for system locale, without giving a specific locale) Java returned to them instead of fixing the locale and getting the date or getting the parts with relevant functions.
I have a relatively short fuse for people who doesn't read (or at least skim) the manual of the library they're using.
The hegemony of software only accepting . has de facto pushed the standard everywhere for computers, but here in France I still write with a comma, but type with a dot.
A few years ago Excel and some other softwares started to be locale dependent and I never wanted to burn my computer this much
French dev currently working for a French but global client, here. The UI of the timesheet app is in English but the fields only accept `,` as decimal point. It's so needlessly confusing.
That's one of the great boons of localization. The webapp knows you're in France, so it tries to do the right thing, while giving you a US English UI. I experience the same thing, but got used to it somehow.
Another good example is how "İ" is popping up everywhere, even in English, because of misconfigured locale settings and how changing case is affected by it. We (Turks) are responsible for that, sorry (We have ı,i,I,İ =D ).
Cyprus and Peru use , for decimal point for non-currency amounts and . for decimal point with currency amount. So it's not even consisent inside some languages.
To add to the complexity of the whole situation, some countries don't separate by thousands (every three zeroes). India uses a 2,2,3 system (crore, lakh, thousand).
Petrol stations... I have no idea how widespread this practice is, but at least in Germany fuel prices have 3 decimal points to better confuse motorists. The third number is usually displayed smaller and is of course always a nine. So, if you see the price for a litre of diesel at e.g. 1.62⁹ €, you might forget to round it up mentally.
International standards say that either dot or comma is acceptable as decimal separator and thousand separators are optional spaces, typically a half space when properly typeset.
ISO 31-0 (after Amendment 2) specifies that "the decimal sign is either the comma on the line or the point on the line". This follows resolution 10[1] of the 22nd CGPM, 2003.[2]
For example, one divided by two (one half) may be written as 0.5 or 0,5.
For example, German speaking countries use a comma instead of a decimal point, whereas the latter is used as a group separator. The German word for decimal place is "Kommastelle" (= "comma place").
If you're going to make a big claim about sort speed, tell me how speed is better/worse for various data. How do the algorithms compare when the data is already ordered, when it's almost (but not quite) already ordered, when it's largely ordered, when it's completely random, and it's in the opposite order. This stuff, as well as the size of the dataset, is what we need to know in practice.
Rather than, or at least in addition to, raw measured speed on a specific piece of hardware, which is often affected in hard to understand ways by niche optimisation choices and nuances of specific hardware, I actually really like the choice to report how many comparisons your algorithm needed.
For example Rust's current unstable sort takes ~24 comparisons on average for each of 10^7 truly random elements to sort them all, but if instead all those elements are chosen (still at random) from only 20 possibilities, it only needs a bit more than five comparisons regardless of whether there are 10^3 elements or 10^7.
Unlike "On this Intel i6-9402J Multi Wazoo (Bonk Nugget Edition) here are my numbers" which is not very useful unless you also have the i6-9402J in that specific edition, these comparison counts get to a more fundamental property of the algorithm that transcends micro architecture quirks which will not matter next year.
"My boss wants to buy systems with the Intel i10-101010F Medium Core Platinum (with rowhammer & Sonic & Knuckles), can you buy this $20,000 box and test your program so I can write him a report?"
It does give some insight into what you seek, at least. For example, “We find that for smallern≲262144, JesseSort is slower than Python’s default sort.”
I’d like to see a much larger n but the charts in the research paper aren’t really selling JesseSort. I think as more and more “sorts” come out, they all get more niche. JesseSort might be good for a particular dataset size and ordering/randomness but from what I see, we shouldn’t be replacing the default Python sorting algorithm.
Concorde development was a (UK & France) national project. They would have had easy access to military aircraft. Aircraft like the Lightning might only just have been able to intercept but would easily have observed pre-arranged tests.
It's almost inconceivable that the test flights would not have been closely recorded, especially the significant ones including trans-sonic and supersonic ops. Despite the best design and air-tunnel work, you'd expect that things would go wrong and you really want to learn as much as possible from any incidents/events.
Unfortunately, all this happened well before the internet age, and so records and images are not so easily found :(
