I do find the really old android versions to be quite frustrating. I don't particularly know what I'm missing, but it feels so not good buying a device and seeing that under the hood it's Android 11 (2020).

I suspect it's mostly that e-readers tend to use pretty old chipsets, & that no one has bothered updating support in a long long time. Maybe perhaps possibly there is some technical gotcha but I expect its more an issue of neglect.

Whatever the case, incredibly discouraging. I've looked at Boox Palma's and others but heck no I'm not buying such a clearly unsupported unloved system.

Removing the "Market expert" which uses OHLCV (Open, High, Low, Close, Volume) also drops the sharpee from 5.01 to 1.88 while also increasing the max draw down to 13.29% (v.s. 9.70% for the index). I'd be very surprised if the pre training of the base model was the only source of leakage...

Nothing really. I invest the majority of my money. I'll buy the occasional $50 video game and get take-out a lot, but I don't have any large expenses (modulo rent and utilities) or expensive hobbies. I have the money to go travel on vacation or attend live concerts, I just don't want to and would rather stay at home.

I make ~$190k/yr. I work 32hrs/wk instead of 40hrs though, and I like it a lot more for my mental health - which I'm able to do because my salary is high enough to support my lifestyle with the trade-off of earning less per week.

About a decade ago, my main "hobby" was writing. I finished and self-published two books that ended up way more popular than I expected.

I understandably was fairly burned out by writing after that. I also tend to cycle out hobbies. So I got into making electronic music for a bit. (Fun but hard.) Lately—a surprise to me—the hobby that's been the more rewarding is knitting. I think I just really needed a more tactile thing to do in my free time. I've been really enjoying knitting and it's so much fun picking up a new skill.

But the whole time, there's a little voice in the back of my head going, "You know, if you spent this time working on a new book, you'd get more money and recognition..." Hitting middle age and starting to really feel the finite nature of time definitely doesn't help.

I wonder if it's something similar for you where it's easier to sink time into random projects before you start thinking of your time as a finite economic resource.

Unfortunately, whether or not a term is really offensive is a combination of what it is, who said it, and when/where (at least in the common-sense definition). Unfortunately, because this is directly opposed to our (at least in the US, and in most countries rooted in liberalism) sense of fairness which says that rules should be applicable universally, across all people and in all contexts.

Which is to say… policing speech is a problem best avoided!

> free apps apparently are an uphill battle in walled garden ecosystems.

How so? I manage well over 10 App Store Connect and around 7 Android Play Store accounts all with 1-3 apps in them, all free, no IAP, no cut for Apple. I've never felt like it was an uphill battle.

While the app review process is incredibly flawed, I haven't experienced anything that paid apps or apps using IAP run into as well. As in, free apps aren't "targeted" in any way I can see.

Have we got all the low hanging fruit, or have we moved the floor up and new fruits are low hanging. How much better life is now depends on what you want to measure.

For example, even with vastly more cars on the road road, our air quality is better in most major urban areas. Some of that is political, but a lot of it is technology advances since the 70s.

The cars themselves are faster, safer and more efficient. Again some of that is political policy and a lot of that is technology.

You can now light your whole home for the same amount of energy that you would have used in the 1970s to light a single overhead fixture in a room. All on the back of technology that didn’t exist until the 90s.

For a mere $50 a month you can talk to anyone anywhere in the world in high quality audio and video for an infinite amount of time. In the 1970s just calling the next city over was a cost you had to worry about incurring, let alone calling someone half the world away.

Almost all of the vastness of human knowledge is available for free or nearly free online, expanding your reach beyond what your local library has in stock.

Yes there is a lot of junk out there. But there always has been a lot of junk. There have always been snake oil salesmen and scammers. There are more of them with new scams enabled by technology sure, but again that’s been true of all time. I don’t see evidence that we are uniquely overwhelmed with garbage relative to the benefits we’re accruing.

>I recently heard someone say "I've never had a job that didn't involve at least some Python".

Tell me you've been in the field for less than 10 years without telling me.

Python is a joke language with a joke name. The only reason it ever caught on for AI is that someone wrote a few good math libraries for it in the 2000s, and its' rise is entirely incidental to that.

To be honest, I've never really understood the need for a stand alone reader.

I read a lot of ebooks, but it's almost all on my laptop with calibre. I tuned the color scheme to be easier on the eyes at night and it's honestly fine. I used to have a kindle, but I lost it in a move long ago, and haven't really missed it.
Show HN: Simplest and cheapest absence management app
by danesto | 2025-06-02 14:45:56+00:00
I've created an absence management app for companies that don't wanna spend ridiculous amounts of money for overpriced software because it offers a lot of features alongside absence management you're not gonna use ever. The app is simple to use. Offers just Logging option - where you keep track of company's absences but also full request-approve system - where employees are also users of the app sending absence requests for approval. Check it out and feel free to let me know your thoughts. * App is still in beta so if you wanna early access and quote just submit the form on the website and I'll get back to you!

Instead of modifying the plane to support an unpressurized bomb bay in a pressurized plan could they not pressurize the plane at all, and provide the crew with breathing equipment?

> They also need to have control surfaces designed to take off with a full load and land empty. Airliners don't have to take that into consideration.

Is it the take off or the landing that would be the problem? If the take off could they use JATO?

>Don't put stock in business relationships.

If this is your mentality, is it any wonder you aren't valued?

People post things like this and I'm not sure they have any emotional intelligence whatsoever. Sure, your work/job doesn't have to be your entire life. But what about a little pride in what you're doing? Working with smart people towards a goal to do something useful?

If your mentality is "just show up for work, do what they ask and go home" then it should be no surprise you're at the top of the list to get laid off. I wouldn't want to work with a person who "puts no stock in business relationships".

> Just move up an abstraction level and put that flow into planning the features and decomposing them into well defined tasks that can be assigned to agents

This doesn't work because you still have to read and verify all of the stuff your agents produce

So the new workflow is: Move up an abstraction level to use an agent to produce code Then move down an abstraction level to review the code it produces

This sounds like way more cognitive overhead and way harder (and therefore probably slower) to do than just writing the code by hand in a good flow

With time and focus any person can beat the market. The market is wildly irrational, so rational actions are not the deciding factor. It is being able to spend all your time and focus watching the data. The question is whether this can be reliably outsourced to machines and what level of effort will it take.

A very simple exercise is to go and watch the live data for a single stock for 1 hour. You will see that it moves up and down and has trends. After 1 hour you can have an idea of an entry point, pretend to pick one, continue to watch, the odds are much greater than 50% that at some point the stock will go above your entry point in the next hour. It only doesn't if you bought into the top of a solid downward trend.

And that is the very basic example, but pair that with an understanding of options and a hedge strategy for the unlikely chance that you bought in at the top of a solid downward trend.

The last piece is to watch and understand Level II data and I reliably believe anyone can "beat" the market. The issue is that you literally have to monitor it consistently with a clear focus, can you do that with more than one security?

What portion can we reliably have machines do without some risk that the machine makes a tremendous error and blows up the account?
by metalrain | 2025-06-02 14:47:34+00:00
I think what and how are so tightly linked, you need to know how to make a thing so you better know what thing to make.

Let's say you want to build worlds fastest car. You can order the pieces and maybe build a car from someones instructions. But to know what makes car fast and how to build it you need to know more and more intricate details. Physics, material science, 3D printing, engineering. How do you measure traction? What shapes increase downforce?

That is how I see AI tools. You can get "off the shelf" ideas on different things, even complete small things, but you really need to be or grow to match the challenge you are facing.

I have spending habits that will probably make a good chunk of HN feel a little sick. I offer as a counterweight to all the frugality that inevitably accrues in these sorts of threads. Sorry, Financial Independence, Retire Early folks. Read at your own risk. Judge if you will.

Income is $450k / yr, engineer, 39 years old, no kids and no plans to have them. I have a chronic illness and retirement seems a distant and not very pleasant prospect. I like working and like to enjoy life.

* $5k / month on rent. (Nice apartment in a high cost of living city).

* At least $7k month goes into savings (I’m not totally financially irresponsible!)

* One pretty ordinary car, expect to drive it for 10 yrs, usual costs.

* $5k / month average on travel. My biggest luxury. I fly international business class sometimes but only when it’s “cheap”.

* $2k / month on groceries, wine, dining out. I enjoy fine dining.

* $3k / month on clothes and accessories. I’m a woman and I have a weakness for nice things, worst of all for designer bags. Yes I know it’s frivolous but the marginal utility is there for me.

* $1k / month on a personal trainer. Could I have the same level of fitness without it? In theory yes, in practice no.

The thing I wish I had more of is time, not in the sense of “retire and don’t work” but in the sense of “it would be nice to take a slight pay cut and work only 9 months of the year and travel more and spend the rest of the time reading, studying math again, and doing interesting projects.” Unfortunately that option isn’t really open to me, outside of consulting which I have no appetite for.

I didn’t get into engineering for the money, but out of love. I’d have done it anyway. But the money is nice, for sure. I save some and don’t feel the need to be unnecessarily frugal with the rest. I know I’m incredibly fortunate. Your mileage may vary, and especially if you have kids. Make your own choices according to your values.

I think this advice works a lot better if you interpret with finer granularity than either "job is my ideal passion" or "job is soul-crushing suffering purely for economic gain".

Very few people get to take the thing they would do completely for free and make money off of it. At the same time, very few people have a job where every single aspect of the work is miserable toil that brings them no joy.

Work is complex and there is a continuum of jobs that have more or less aspects that resonate with you. I think better advice is to seek jobs that let you bring more of your joys to bear while acknowledging that no job will be paid fun. And when in a specific job, try to find the aspects of it that you love and make the most of those to the degree that you're able.

We have a much richer ability to navigate our careers than simply treating any job as all bad or all good.

Robotics is definitely getting more accessible! But keep in mind it’s a whole different world from traditional web or desktop software development, so don’t be surprised by the relatively steep learning curve. Keep at it though!

- Buy a small robot kit from Amazon or a local reseller. Yahboom make some good robot toy car kits. Hugging Face have the open source SO-ARM101 that plenty of companies manufacture and sell now. Expect to spend about $250 USD including a Jetson Nano for a good kit, up to $1000 USD if you want some more sensors

- If you can’t afford a real robot, play around with simulators like Isaac Sim and Mujoco

- Check out LeRobot, excellent framework for ML robotics from Hugging Face

- Learn the basics of ROS (pubsub), even if you don’t end up using it, a lot of the industry jargon and design patterns come from ROS so it helps to understand it. Think of ROS like Ruby on Rails, it’s a heavyweight batteries-included framework with lots of opinions.

- ROS does have some nice libraries for manipulation (MoveIt) and navigation (Nav2) using more classical (non-ML) methods

- Leverage AI tools such as ChatGPT and Cursor when you get stuck, it’s a lot faster than Googling when you’re just getting started and don’t even know the right term to search for.

- (Shameless plug) Check out two tools I’m working on: mcap.dev for logging and foxglove.dev for visualization

I was so enamoured with the original gen2 Nook I acquired a pile of them. The batteries, unfortunately, are all dead and I've found no reliable replacements. Then there's that slimy rubber thing that happens after so many years, and that makes anything intolerably miserable to handle.

I sure did adore the old black n white Nooks, which I could load as I pleased with any file of my choice, often converting text and PDFs to ebook with Calibre.

> Pretty sure that, these days, Tolino devices are literally just Kobo hardware with Tolino firmware loaded onto them.

I only read the German Wikipedia entry [0], but the way that sounds is that they are different hardware, but now using an adapted Kobo OS (with ways to switch between the normal Kobo mode and Tolino). But that’s just my impression, I have no further clue :D

edit: This [1] says you are right

Great idea! Will it highlight parts where the professor says something like "this is important and will be on the exam...". All of the information on the exam (which dictates the majority of your score in the class at most US universities) must be conveyed to the student one way or the other (worksheets, lectures. etc.). A cool runoff would be an "AI Exam Prep" which guessed what would be on the exam, based on previous exams and where the info came from

IMHO many "open source alternatives to" should drop that tagline.

This sentence is the first thing I read, and likely the last.

I don't know what "Trello" is. I don't see what your project or app could do for me. Even if I knew Trello, I wouldn't know why does it need an alternative. (Trello was (is?) great for personal use, by non-technical people.)

"A powerful, flexible kanban app that helps you organise work, track progress, and deliver results—all in one place." This is your selling point, not what your app isn't.

A high inflation rate can significantly reduce demand for US government debt. Same applies to corporate debt - that's why inflation indexed bonds exist (called TIPS for US debt). They are not a big part of the bond issuance atm but they could grow massively. In my outlined scenario the US gov won't be able to issue more TIPS because of their fiscal situation while profitable corporate issuers could.

I can't answer that question exhaustively, but they do have a USB drive mode* and airplane mode, if that's something you care about.

Though the models with ads (basically all of them) do track impressions of all the ad placements around the device, which includes the lockscreen (the display shows ads when it's in sleep mode, both before and after you press the power button), and a banner on the home page.

* - Amazon removed the ability to download books from them to put on your Kindle, but the new ones do still have a USB drive mode

It would be nice, heck I would accept a 50% pay cut for a better team since I didn't even need all the money I was earning (except for my current survival I guess), money isn't what it's about to me so long as I can feed myself, but my job hunt now isn't really about team value anymore. It's not something I can afford to think about when any job has to do for the rent. I could go back to stocking shelves if the next data entry thing I feel over skilled for doesn't get back to me

I like my hobbies, just I can't pretend to enjoy them all day when my current lifestyle has been unsustainable for so long. It was easier start of the job drought and I could do whatever I wanted and it felt nice, picked up some (unmarketable but fun) skills. Now it's all caught up to me.

"At least the gig economy is an option" is a thought that appeared in my head recently

I think both of these things can be true at the same time - the issue with a lot of utility-based value is that it often comes in the form of unsustainable heroism. My capacity to feed back interesting thoughts about product and strategy in domains I'm familiar with is probably greater than your capacity or desire to consume them, but my capacity to do various forms of high-precision grunt work (set up configurations for clients, misc. project work, ship XYZ feature into the product) is much easier to consume and ultimately overload.

Closing that million dollar deal as a sprint might be memorable, but being the go-to configurator for Azure cloud services isn't, and the difference between heroic level systems management and mediocre button clicker requires hard squinting if you're non-technical. Hell, I'm technical and would struggle to tell the difference just because IT isn't usually my domain.

And if the person you're working with has no appreciation of what an average performance is, any mistake will be seen as a defect even if what you're doing is otherwise heroic.

Scrolling social media feeds is like smoking an infinite cigarette. What if the cigarettes weren't infinite anymore?

Cigareditte is a proof of concept illustrating what consuming social media actually looks like. Uses Hacker News API as social media backend. Any potential in developing this into something more usable like a browser extension that applies to social media sites of your choice?

Where does the rating come from? Do you understand what all those words mean? It looks like you copied someone's rather subjective opinion. Because e.g. "bollo" and "caliente" aren't inherently profane in Spanish. Or do people think the hot water tap is leering at them? "Oye, tia, que caliente qu'et-ta!"

Appreciate your perspective — and I agree, technically, free apps can be published without issue. But from my experience (and others I've followed in the FOSS space), the “uphill battle” isn't about being blocked or targeted — it’s more about discovery, sustainability, and alignment with the platform’s incentives.

On stores like Google Play, the design favors apps with ad revenue, IAPs, or growth metrics — not minimal, ethical apps with no monetization. Free, privacy-respecting tools often get buried or flagged for things like lack of user engagement, sparse permissions, or not following monetization guidelines (like not using Google’s billing).

That’s why I released my app, MBCompass, on F-Droid first. It's where users expect simple, ethical apps — and where visibility isn't tied to commercial strategy.

So yeah, free apps aren't “targeted,” but the environment isn’t really designed to support or surface them either.

I completely understand the allure of this line of thinking, but a better way to quantify this is people who are collecting a paycheck vs. people who are taking on risk.

I have noticed as I got older that many paycheck collectors are totally unaware of risk (as I was), likely because it plays no part in there day to day life. They are hyper-focused on the minority whose bets paid off and got obscenely wealthy, and totally unaware of the massive graveyard of those who incinerated their life savings. Hell it's not uncommon for a business to collapse because of honest mistakes made by the paycheck collectors, who upon the business closing just went and got another job, maybe after being on unemployment for a bit. For the risk takers, I can tell you that unemployment checks don't cover lost equity.

The rub here is that the paycheck collectors also highly value the "good" risk takers. Most people, given the opportunity, would put their money into a fund managed by someone with an excellent track record.

If you're employed, you're probably valued and useful in some respect.

I think a much more important question is: what are you being valued for and does that fit with your goals?

A person who wants to build skills to take on the world's most challenging problems probably doesn't want to be valued for their ability to grind on the tedious tasks or because they look good in marketing materials, for example.

Could be. My own frame of reference is the following:

There's 3 core parts:

- Electronics (batteries, resistors, capacitors, etc) - Robotic hardware (motors, sensors, microcontrollers, etc) - Software

The electronics learning is always going to apply to start there if you need to, then depending on your goals the hardware and software will vary.

For simple DIY projects I'd start with getting an Arduino or Arduino compatible board and just play around with building things with sensors, LEDs, motors, etc. You'll find lots of kits and resources online for simple Arduino projects.

More complex projects are probably going to need to be Linux-based (AI, machine vision, etc). In which case you might want to look at building something with a mini PC, Raspberry Pi, NVIDIA Jetson.

These days robotics is super accessible, but can cost a bit depending on what you want to do... That said, most of the time you'll find there are cheap ways to build POCs to validate your ideas first.
