looking at https://en.wikipedia.org/wiki/E6B it looks like it would be very difficult to calculate, say, 124 × 53 × √14500 ÷ 0.77 on an e6b; it seems to only have two general-purpose scales and no cursor

on a standard linear slide rule, the most obvious way to do this calculation takes five moves:

- move the slide to align the left d scale index with 1.24 on the c scale;

- move the cursor to 5.3 on the d scale, thus putting it at the position of 6.57 on the c scale, which you know means 6.57 thousand;

- move the left index of the d and b scales to the cursor;

- move the cursor to 1.45 (not 14.5!) on the b scale, thus putting it at the position of 7.91 on the c scale, which you know means 7.91 hundred thousand;

- move the slide to align 7.7 on the d scale with the cursor;

- read the answer, 1.028, off the c scale at the left index of the d scale, which you know means 1.028 million. (the 6.57 was an approximation of 6.572 because on a normal-sized slide rule you can't read things off to four significant figures that far up the scale, but you can definitely tell 1.028 apart from 1.025 or 1.030, though possibly not 1.027 or 1.029)

i think you can do this same calculation in just three moves by using the ci and di scales (and maybe a instead of b), or using cf, df, and cif for some of the calculation, but i never learned how to use a slide rule properly because i was born after the hp-35; hopefully someone who was born before 01960 reads this thread and can explain a better way to do it

you can do this with just c, d, and l scales if you have to, but it takes some mental work (and extra moves) for the square root. at a given length, circular slide rules are better because they save you from having to choose between the left and right indices, and their maximum dimension is smaller, being almost τ times smaller than a linear slide rule of the same length — but they also tend to weigh more

looking at https://upload.wikimedia.org/wikipedia/commons/c/c4/StudentE..., the e6b seems to have c and d scales (this is an edit correcting my earlier version of comment, which claimed it didn't). they're the scales in this photo that say 'imp. gal.' at the top. but for taking a square root i think you're on your own, and it doesn't seem to have a cursor, which is a significant drawback. and i'm skeptical of the play in the grommet used as the pivot; it seems like that could really hurt your significant figures

so, probably do not buy an e6b in order to learn about slide rules; you will be almost as disappointed as if you bought it in order to learn about computers
> Hi - can Grace support partial commits somehow?

Not at the moment, and probably not for v1.0 unless that bubbles up as a huge blocker.

You could accomplish it with something like:

- Make the changes in your branch
- Make a new branch off of `main` and cherry-pick the changes you want from your branch into that new one
- Commit and promote from the new branch; at this point you can delete the new branch
- Auto-rebase will run and propose a good merge to your original branch, which would include the partial changes you now have both in `main` and in your branch.

I still have to write cherry-pick - not sure that I'll call it that - and promotion conflict processing using LLM's. But something like the above steps would do what you're asking without too much effort.

There's no way to tackle the entire surface area of 20 years of Git in one release. I'm sure we'll see workarounds like that in v1.0 and learn from them to improve 2.0 and 3.0.
Apple made a terrible mistake: it told the truth
> As a consumer, isn’t that a good thing?

A foreign nation dumping massive volumes of their heavily subsidized production onto your local market and putting your domestic producers out of business is not a good thing for any nation. If China could produce EVs far cheaper than the United States without using vast amounts of coal, and without those heavy subsidies on the whole supply chain let alone on manufacturers directly, then there's a free market argument for going tariff free, but as it stands going tariff free would be just letting dirty, unfair competition to go unchecked. It'd be political suicide let alone national industrial suicide.

Maybe the sheer amount that strings are getting iterated through makes storing length computationally cheaper? Unless you're using very optimized methods to work with the string, the majority of string operations involve a lot of iteration and comparison. Vectors, on the other hand, have much more varied use and possibly may never be iterated at all (though they likely will somewhere).
i'm guessing you mean slide rules, and that the apollo astronauts used a slide rule of the same model as yours, not the one you bought at the antique store

the prices i see on ebay suggest you could sell most of them for significantly more than you paid; unless you have slide-rule-fancying heirs, try to do this before you die, because otherwise they're likely to end up in a dumpster
People making $200M have convinced people making $200K and $20K that each other are the bad guys.
Since quantum computers can stimulate classical computers, presumably they can solve NP-complete problems, since classical computers, by definition, can. Perhaps you mean that they can’t solve NP-complete problems in polynomial time, but we don’t even know that of classical computers, so you would presumably have shown that P≠NP, which would be fairly impressive.
When the prices are listed pre-tax then use the amount of money you have in pre-tax dollars. If you have $40 and the sales tax is 7% then use your phone to divide your $40 by 1.07 and that's how much you have to spend. You don't have to do the multiplication for each item individually and items with different tax rates are typically entirely different classes of product which are sold in different stores.
If you watch this ad back to back with the classic "1984" Mac ad, I found it hard not to feel that Apple has become the "Big Brother" it once despised.
Interesting - I love the sound of birds and can go right back to sleep when they are chirping outside and I have the window open. Road noise on the other hand...

This "original" hacker's dictionary was discussed there, but is distinct from the version headlined there, which is due to Eric S. Raymond.
That's pretty bad for a terminal utility and file manager. The thing should never, ever connect to the internet for anything unless explicitly told to by the user. I didn't notice this, thanks for pointing it out.
One caveat: if the blobs (e.g. images) in the DBs are static, and transactions are read only/writes happen infrequently, then having all your blobs in one SQLite DB makes for an insanely easy backup strategy, compared to having thousands of smaller files on the filesystem.

And it only requires two tables - one table for blob storage with an indexable column; and another table where you're storing the metadata associated to the rows in the blob table.

For a small number of users and simple apps, it can be an ideal solution. I know, because I've tried.

Ask HN: How to hunt for business ideas while working at companies?
I’m always curious how engineers/product people discover new business/startup ideas while solving their current problems at work. Let’s say you are working in some specific domain like ML models for ads ranking/marketplace or designing and maintaining the payments API, how do you go about finding problems that touch the space of your day job that are ready to be solved? In my limited experience, these low hanging fruits are not necessarily obvious to mid level ICs. Of course I could be completely wrong and just haven’t looked in the right places or asked the right questions. What should I be looking for? Who should I be talking to?

An example of such a startup origin story is this company that was acquired by Shopify. The first bit talks about how the founder came up with this idea after having worked at a company in a similar space.
https://www.unusual.vc/post/deliverrs-product-market-fit-journey-michael-krakaris-on-enabling-prime-for-all-e-commerce

I’m sure it wasn’t as linear of a story as it’s written, but I still think it’s a good example.

Would love to hear everyone's thoughts!

TFA says you can teach it new facts, but it's very slow and makes the model hallucinate more.
You can call yourself whatever you can get away with. There are a whole lot of people out there that have never slung anything but React-flavored JS being called developers and being paid to do it. The industry needs these technicians too, I guess.
I don't find it offensive, but I do think the idea would have worked better if they visualized it as a compactor, and didn't visualize things getting destroyed. It doesn't make sense to focus on all the destruction and then be left over with a fancy iPad. It's a compact version of a whole bunch of destroyed things?
I now think you've said lots of ban worthy things (depending on who you ask ofc) the joy of Google is that they wont explain where or what.

I'm exceedingly jealous. I don't think I've ever lived somewhere that I could see it, no matter how clear the night. Looking at images of "north america at night" vs "europe at night" I can see why.
Unfortunately it's a pretty common issue in react forums. There was a discussion recently about there being no way to create s3 upload urls in react. I mean of there are several npm modules, but non have react hooks so nothing was viewed as usable.
The only reliable way that I finish my side projects is by using them for something I need to do anyway. If I can use something I made by going slightly out of my way, I get to improve it to completion (at least for the use case I'm doing). But if I have to go significantly out of my way to use it, then it gets abandoned like everything else.

That, and I have a tendency to put most of the documentation into a quick overview and really, really detailed error messages. In fact I'll often have quite a bit of code trying to guess what the user's intent was, because that makes things easier for future me.
breitling's version does seem to have c and d scales, but it seems not to have a cursor, so it looks like it can't handle the very simple example i described in https://news.ycombinator.com/item?id=40324625 without a lot of extra mental work. and how would you do a square root on it?

the marketing shill splog page in your third link describes several other slide rule watches, but unfortunately it's too busy with huckster patter to explain what their capabilities are; i suspect they suffer from the same weakness
Couldn't this be considered more like an en-bedabble HLE emulator? The high level aspect is much more sophisticated than we've previously seen which allows for all those enhancements and better integration with the host system, plus all sorts of (I imagine) warpers to make the recompiled code work on the host system, which is kind like an emulator. Or maybe more like WINE + recompiled code.

And of course, as noted in the video, the hard part of reverse engineering is still there, so you still have to figure out the meaning of each piece of code and give it proper symbols, but now you have this really nice pre-generated scaffold all around it :)
I see two parts to this. One is the role of user choice in deterring system damage from bad apps, and the other is the role of app stores in shielding the user from having to make this choice to begin with.

On the matter of websites, if the decision rests on individual choice, then individuals certainly have a choice to visit (and thus trust) a particular domain name and cert. That users need merely type in a name, and that there's a giant company helping you search for these apps, simply means that web apps are easy to find and install (and native apps are only slightly harder to install).

Then there's the role of the app stores, which I imagine practically deals with the supermajority of garbage, spams and scams out there. We could also have orgs whose sole job is to maintain lists of credibility, if that's what people want. Then a web user could download a browser extension or use a browser that subscribed to these lists by default. In some ways that's what ad blockers are, except ad blockers are even more precise and there's nothing quite like it in the native world.

I had to learn cobol last year. Not hard if you have read lots of books from the 70s and 80s and have a strong background in algorithms. It is expensive and annoying to maintain these systems, but until there's a business case to replace the underlying application, he's safe
Everyone knew it went into the database and the fair use if you had been around SO since the beginning was always part of the deal. SO even serves ads.

From the ground I cannot see it (I'm a bit north of london latitude wise so it should be better), and we have nicely combination of areas of greenhouses and petrochemical companies burning off here so it might be far worse than central london unfortunately. I'm not too high up but my view north is quite ok ... and unnatural orangeish and void of any pink.
I would love for official re-releases and remasters to be made with this method. I'm not sure about N64 titles, but I know many developers have lost the original sourcecode to beloved classic games. This had lead to a lot of re-releases either simply being an emulator, or being a complete port not based on original code. Star Ocean 3 is an example of a game being re-released as an emulated game, and it suffers from unexpected crashes and in general offers no big improvement over playing the original game. Final Fantasy 8 Remaster is based on the steam port, which was based on the original PC port. Some basic functionality, such as full analog movement (instead of 8 directions) is missing, and in general the game behaves somewhat differently than the original PS version.

We are getting many low effort rereleases. I almost never buy them because the original versions are just as good or better, and I own a great upscaler. I would love to see companies use these methods to make better re-releases.
> As a consumer, isn’t that a good thing?

Unfortunately not really, because any gains that would be had from prices going down are automatically erased by the Fed creating enough new money to ensure that average prices continue to go up. And rather than that money being injected broadly into the economy or spent by the government on useful endeavors, it just reaches consumers in the form of loans. So effectively EVs getting cheaper means that housing gets more expensive.

Would we know if they went to space? How long would a geostationary satellite remain?

It's both haunting and brilliant to think about the idea of entire other intelligent species and civilisations having lived on this planet without us ever knowing. Fire and iron and cities and empires and "great people", cultures and religions and stories and families... Civilisations and species rising and falling throughout the eons. It feels a little reminiscent of Sagan's "Pale Blue Dot", but on the scale of time, not space. I wonder if they might have considered this too.

“ As described in this post, decompilation project is tedious and laborious. Therefore it's easy to lose motivation and leave it in backburner for a long-time. The solution I have found is consistency, everyday try to work on it a bit as all effort will compound.”

I’m current self studying calculus. This is exactly the situation I am falling into. I now spend an extra hour and a half or so at work in the lunch room (my workplace is 24x7) and go through the calculus book. I’ve been doing this for 6 weeks or so, and though my progress may seem slow to many (I just got through limits) I understand the material properly.

(In terms of 6 weeks, I did the prerequisites chapters first which took some time, then I had a holiday, and I spent almost a week and a half on the Delta-Epsion definition of a limit - and I do all the problems in the book and there are a lot)

while it's true that wasm was originally designed to run primarily on the cpu(e.g., executed in a sandboxed environment on the main thread, which is generally managed by the cpu), the assumption that wasm only runs on the cpu might be becoming a bit dated. esp. as a result of webgpu and frameworks mentioned above, wasm is increasingly capable of executing on the gpu imho.
This also appears to be happening in the southern hemisphere as well and growing brighter. My layman understanding is auroras are the result of coronal mass ejections interacting with Earth's atmosphere, but I don't recall these incidents being large enough to be so visible in the northern and southern hemispheres simultaneously.

Bumble's entire product value was initially built around improving conversation initiation, which is a major hurdle in the dating app market.

So no, you absolutely are going to need the virtual back and forth so you can hand it off to the real people to pick up from, and it makes a lot of sense an executive at Bumble is thinking about it this way.
