At subsonic speeds, airlines have been slowing planes down to save fuel. There have been significant investments in data collection at all phases of flight resulting in models of the most fuel efficient way to fly. For example, Rolls Royce has a case study with Microsoft where they used AI models to teach pilots how to fly in a way that would save more fuel.

My guess is running a startup is like running a marathon. The idea of it is great to many people, but as people start to train they realize all the work it takes and drop out. People get into things without fully understanding it all the time. The few that really love it or enjoy the process makes it to the starting line.
You just did. You engaged. This is valid criticism, and not at all in bad faith.
A cynic would say that the BBC is preparing the public for the Online Safety Bill, where many small online ventures will become unviable.
This is why I stick to a terminal based editor. You can use it practically anywhere with minimal resource usage. You can use it remotely so any machine is your workstation. You can use it on a machine without a GUI at all.

With the new AI plugins I doubt even Jet Brains will be able to offer much over what Vim and Emacs can provide with fugitive, magit, fzf, etc. providing best in class features while still running on actual terminals.
That honor belongs to XML
Theoretically they would not be needed, but I agree that the mechanism of some ultrasound sensors is much more reliable. Given that they are as cheap as they are, I don't know why a car would leave them out in the first place given the margins of modern cars.

I had a few year of expericene with AVR assembly (x86 was a pain)... but getting younger people to learn it is a pain.

What would be the best way for someone today to learn assembly? Which architecture, chip, devkit etc. would be an ok start, without too many complications (init process, toolchain, good documentation, etc.), preferably on linux?

Good luck forcing quality of life reduction as an explicit policy goal. Or betting on less contact widening of our circles of empathy in the way we must to address global, long-term problems like climate change.
I think the real message is to reflect and know what you want out of life, and to know what you're optimizing for. And not just getting away from your current situation.
We solved this problem with SQL (at least following best practices). And considering the LLM space is likely to be highly concentrated and sophisticated, why can't we solve prompt injection in this case

I am not disagreeing with you, but the width of “tokens” we parse does matter — it’s much harder to spot a typo in a long word than in a short one, and one tends to read assembly by pattern matching on the instruction word, so I believe better, but still relatively short names would be the optimum.

(E.g. jump_if_greater would not be that good, jge is too short and unless you actually know what it is, it is hard to decipher, jmp_ge is not a bad compromise)
it's probably already obsolete
ah ok then well that's settled
In 2D games it is often times some kind of object hierarchy (scene graph, display list, nodes) imposed by the engine/library, which never plays well with ECS IMO. In these instances I think it is better to just inherit from a carefully thought out god object (yeh yeh I know).

If you are using a low level rendering library, or immediate mode library, you can more easily define your state however you want, but still ECS incurs massive overhead compared to basic arrays of structs. If your language allows structural typing then ECS seems to me as having little benefit.

Well, all mentioned in the article do bullshit jobs. "Advisor to high networth individuals" "Career coach" and other bullshit.
(1) The killer product encompasses “all of the above”, if you really are going to buy five of them God help you because with all the mistakes vendors will make and you’ll have to work around plus the overhead of moving data around you’re in for it.

(2) A major difference w/ the conventional software development CI/CD pipelines is the sheer size of the data involved. When you are dealing with “tiny data” you can waste resources on Docker, but when your foundation model is 100x the size, when the training process is distributed, and takes a day, the quantity is taking on a quality of its own.

(3) The worst performance sin is moving data around although this will be necessary so far as the system is distributed. Avoiding excess data moving can be the difference between training a model and failing to train a model, but when you put together a patchwork of ML ops programs you will fin they are moving data around internally for good reasons sometimes and no reason other times plus the easy (and sometimes only) integration method is moving data around. Don’t be that guy!
... still. It's unfathomable why they stopped. They could have singlehandedly created a new semi-national ISP, and they could have sold it off by now to focus on their core competency of launching new increasingly irrelevant messaging apps, rewriting GMail in slower and slower ways, and of course challenging the world, by boldly going where noone has dared going before, dropdown-by-dropdown sub-account-by-sub-account day-by-day they are inching closer to opening the gates of the insanity dimension, and the moment will come when God will get fed up because he/she can't find the fucking property/website/account in Google Analytics...
A nice analogy but it doesn't work.

There aren't that many entrepreneurs who failed multiple times before succeeding at a business. If you look at the big businesses that dominate the US tech economy, they're all first time founders (Amazon, Apple, Google, Microsoft etc).

There are also very few entrepreneurs bootstrapping their own business. Even rich kids go to VC, they aren't usually risking their own funds.

Finally, if you try multiple times, learn something important from each failure, and then succeed, it seems reasonable to claim that this is now due to the skills you developed and not mere luck. You can't even claim it's privilege - it might be, but as this article argues, being an entrepreneur isn't being handed a nice life on a plate even if you're successful.

For sure there are counter-examples where some rich kid spent their parents money trying and failing over and over, then got lucky without learning anything, somehow had an incredibly easy life from that point on and then started talking about merit. But they're going to be the exceptions that prove the rule. The carnival analogy therefore feels like ideologically motivated reasoning of the most common Marxist kind (claiming hard work and risk taking don't matter, that all success in life is the inherited privilege of capital).

Oh boy, I found/invented a tweak that I can't live without anymore. I use an MX Ergo trackball, not sure how it'd fare on a mouse, but here are the magic runes:

xinput set-prop <mouse device id> "libinput Scroll Method Enabled" 0 0 1
xinput set-prop <mouse device id> "libinput Button Scrolling Button" 8

Where you'd change 8 to a chosen mouse button and the mouse device id to its appropriate value from `xinput list`.

What this does is make it so that as long as that button is being held, moving the cursors scrolls instead. It's hard to describe how much better of n experience it is vs. using the scroll wheel. It's much faster, much more precise, and less finger-tiring.

Here's a gist of the Python script I use to set it up - https://gist.github.com/pedrovhb/41e9d5b7b7b5c13fe2c94aa4cee...
You always here about the 5% that make it, not the 95% that don't. Even when you do its easy to brush off why they failed. "Oh their idea was bad", or "they didn't know what they were doing". This is only amplified further by those 5%'ers running around encouraging everyone to start a business. Writing books about their success. Giving motivational speeches, etc.
Is it worth it to host this on an EC2 which might take ~1.5$ per hour (on demand) than running GPT3.5 API for this purpose?

> Cruising at 50km of altitude is one way to solve it. The problem I’ve always had with the idea of rocket-powered rapid aircraft like this is that, presumably, only the very wealthy could afford this.

Surely the primary issues are that the efficiency would be dreadful and that the price would be ridiculous even for “the very wealthy”?

This would only be accessible to double if not triple digit millionaires, and is the gain in time really worth the hassle versus the comfort of a long-range business jet?
As usual, simplicity of this type basically means making the programmer write the boilerplate that the compiler could generate for you. The complexity has to live somewhere, and with "simple" languages, it lives inside your own source code, and that of each of your libraries, instead of living inside the compiler.

I'm not sure why this appeals to so many people, but still: it clearly does. So, best of luck to the Gleam team, I hope it lives up to your needs and desires!

That's not stuff an LLM can't do. It's just presented in a way that makes it difficult to do so.

First the vision problems will require the equivalent of an artificial visual cortex, something we are seriously lacking in artificial intelligence at the moment. Image to text won't cut it here.

Wait, are you saying you don't think you'd have lost the marriage if you didn't do the startup? Surely it wasn't worth it if so?
At what point did I say that people would have to figure it out on their own?

For the sake of this argument, assume the premises that (a) Meta, a foreign corporation, controlling the private conversation of hundreds of millions of citizens is not simply "not great" but unacceptable, and (b) that it is necessary to put WhatsApp permanently offline (as opposed to making it somehow safer).

Steps to a post-WA transition:

(1) Publicly gather a list of messaging services that can be verified to satisfy the requirement to act as WA replacements:

- E2E encryption

- Interoperable under the Digital Services Act (critical)

- Phone number-based IDs

- Fully hosted in the EU and controlled by European companies

- Sufficient operational resources to serve > X number of users

(2) Mass send the message to all WA users "Due to new European privacy rules, WhatsApp will shut down on ${today + X months}. You will be able to continue talking with all your contacts through any of the following apps: [ list apps sorted by capacity, click to install ]. You will need to recreate any groups of which you are currently the admin.". Plaster the same message everywhere, send SMSs, etc.

Compared to switching to a whole new currency, or moving a shitload of bureaucracy fully online during Covid, this seems a very reasonable task for a European government.

Current Status

Embedded: Ready Slint is already being used in production projects by customers (running on an Arm processor with Linux).

Microcontrollers (MCU): Ready. Slint apps can run on MCUs with less than 300K of RAM.

Desktop: In Progress. While Slint is a good fit on Windows, Linux and Mac, we are working on improving the platform support in subsequent releases.

Mobile (Android/iOS): Todo. We haven't started supporting mobile platforms yet, but it is our intention to do so in the near future.

Web: In Progress. Slint apps can be compiled to WebAssembly and can run in a web browser. As there are many other web frameworks, the web platform is not one of our primary target platforms. The web support is currently limited to demo purposes.

It is actually a pretty easy solution because GTP is smart enough to understand you want to avoid Prompt injection, just tell it so, Here is actual output from GTP-4:

Output:

Here is the list of emails found in the text:

I honestly stopped reading right there in paragraph 3 or whatever, it made me too mad.

But i still came here for the comments!
That may well be the reason for the media interest (I'm as cynical about that as you appear to be), but the fear itself hasn't new, and the tech is… well, not quite there, but close enough for the worry to seem reasonable rather than a persecutory delusion disorder.
It would have been nice to get some idea about the relative sizes.
A collection (e.g. an array or a hash map) that stores things. Maybe more than one collection like that, different for each type of entity: monsters, items, etc. (Separate code paths to handle these different types of things.)

Keeping indexes/keys for references, and loops over these collections can do a lot without any upfront complexity of an entity system.
I don't care what caused it, right now he is denying there is a culture of racism that needs to be weeded out despite plenty of evidence to the contrary. I am not saying elon is neccesarily racist but his denial of it and obvious pepetuation of it (and this isn't being called names, look at the actual suits, this is the shit you see in jim crow era movies) means if you support him knowing this you support that also. You can admire his accomplishments but you can't support only part of someome, you support all of this stuff too.

The klan made theit stance obvious they didn't hide it. That's what I am encouraging, if you're going to support racism don't hide behind meaningless excuses.
I honestly don’t understand how you can find google drive better than dropbox.

I wanted to use google drive. It would have given me more space for emails, and I wouldn’t have had to deal with another service.

But even syncing files from my computer to the cloud never worked properly. I kept getting conflicts and files that would always fail. Then there is the ”shortcut” debacle where you can’t sync files that are shared with you on your own computer.

Dropbox just works.
Ha.

I joined the workforce the year after final salary pensions were shutdown. My slightly older peers are all on track for early retirement. I will never be able to retire.

I considered contracting just as IR35 was introduced. My slightly older peers who - literally - got rich and paid no taxes enjoy much better lifestyle than me.

So this makes sense, that as I claw my way to higher income, it's taken away by the system.

All the while having record house prices, plummeted pension performance and now cost of living/inflation.

What a horrible game.
Stress + neglected diet and exercise definitely puts a strain on your body.
You know, good for mighty elon! But he should do what's right because it's right not to please people.

I am looking to build this for a different reason so families (today and future) can chat with a virtual me. I know what you mean tho. I am a parent too.
I absolutely have! Didn't think it was worth the tangent so I'm glad you're bringing it up. Women's fashion is so much more varied in shape, size, style, and fit, and some of it even looks comfortable. As a matter of fact, if you search for high-rise trousers online, most of the results are precisely in the women's section. I think that will have to be my next stop, though it's a line to cross and somewhat of pill to swallow.

As an aside, I have said for a long time that I wish it was socially uncontroversial for a guy to wear a loose skirt or dress in public, and that if I found one I liked I would wear it all the time.
Haystack Agents are designed in a way so that you can easily use them with different LLM providers. You just need to implement one standardized wrapper class for your modelprovider of choice (https://github.com/deepset-ai/haystack/blob/7c5f9313ff5eedf2...)

So back to your question: We will enable both ways in Haystack: 1) Loading a local model directly via Haystack AND 2) quering self-hosted models via REST (e.g. Huggingface running on AWS SageMaker). Our philosophy here: The model provider should be independent from your application logic and easy to switch.

In the current version, we support for local models only option 1. This works for many of the provided models provided by HuggingFace, e.g. flan-t5. We are already working on adding support for more open-source models (e.g. alpaca) as models like Flan-T5 don't perform great when used in Agents. The support for sagemaker endpoints is also on our list. Any options you'd like to see here?

I think you need to leave tech and VC money. VC’s are happy to throw money behind a bunch of smart college kids. Go try to go a different route and see all the doors shut. Also you don’t get to see all the people who don’t try their hand at entrepreneurship because the gamble is too great for them.
I can see a number of data points in the comments, let me add another one.

I started a self-funded SaaS business fairly late (in my 40s). I was tired of being dependent on others, especially as others mostly failed me in the past. I wanted to be independent: no investors, no bosses, no employees. Just me.

It took five years of slow growth to get to a stage where I didn't have to worry about revenue.

Do I regret it? Hell no! It's the best decision I've ever taken in my life.

I am now very happy with where I am: I have a business that depends on very few external factors and runs well. I don't have to worry about investors doing crazy investory things. I don't have to worry about employees pulling crazy employee stunts (believe me, I've seen a good number of those in the past, and the entitlement of many employees is absolutely crazy). I don't have to worry about user numbers, only about paid subscribers and maintaining slow revenue growth. Nobody pushes me for crazy growth.

Most importantly, the business model is simple: my customers pay me because my software improves their workflows. That's it. There is no "monetization", no shove-it-down-your-throat marketing, no tracking, none of that unpleasantness that seems to be dominating today's world. If they like the software, they pay a subscription fee, if they don't, well, they don't, and I have a problem. But so far it seems they do :-)

The only thing I had to carefully manage was my engagement: it's easy to get pulled in and work crazy hours, because in a single-person business there is always much more to do than you can possibly ever do. You have to become good at prioritizing, which means identifying the single (ONE!) most important thing at this moment and focusing on that. But you also have to accept that most things will not get done and be OK with it. That was hard for me, but I learned, and I keep sane hours and a good work-life balance.

I'm posting this just to provide a counterpoint to many negative comments.

PS: if I were to provide one bit of advice to aspiring entrepreneurs, it would be: look for a business that delivers high value to customers with money. So don't start a B2C business that does something easily replicable with a low value. B2B is where it's at.
Show HN: Promptr, let GPT operate on your codebase and other useful goodies
Hi HN,
I've been working on an experimental tool that helps you use GPT to work on your codebase. I'd love to improve the tool if there's interest. New ideas welcome! I think this could also be useful for experimenting with other types of recursive prompts.

It’s a little bit Swiss Army knife and a little bit skynet:

https://github.com/ferrislucas/promptr

From the README:
Promptr is a CLI tool for operating on your codebase using GPT. Promptr dynamically includes one or more files into your GPT prompts, and it can optionally parse and apply the changes that GPT suggests to your codebase. Several prompt templates are included for various purposes, and users can create their own templates.

Got it. The -10x engineer is bad management who are in turn bad because the rest of the business is completely illiterate about anything even slightly technical.
Yes. It depresses me no end that this comes from the BBC. How predictable. You can argue that the Californian sun-always-shines mentality is unrealistic, but you can't argue with the results it generates. Perhaps the British attitude is just normal and not anything in particular, but compared to the attitude of the people at the top it's a culture of defeatism.

I think it may also be reflective of the culture and mentality at the BBC specifically, though. It's well known their staff is completely dominated by Guardian readers. These are people whose idea of success in life is taking control of a powerful pre-existing institution. The sort of people who make wild bets on unintuitive beliefs and end up disrupting industries are pretty much opposed to that value system and it shines through in all sorts of subtle ways.
