3blue1brown is fantastic. Every once in a while I'll be like "what is the intuition behind determinants again?", and boom, there's a thoughtful and concise video on it.

However, there's no magic bullet that will let you learn linear algebra in a couple of hours. At some point you have to sit down and work to figure it out. The field has university departments researching it, so there's a lot more to it than just multiplying m×p by p×n matrices.

I don't know what you mean exactly by beginner, but assuming you have some level of mathematical maturity, UT Austin has an edx course you can audit for free, "Linear Algebra Foundations to Frontiers", and FastAI also have a pretty good free video series/course on it too.
Which violates the warranty. And if the TV can’t phone home it can just refuse to boot. So you need to root and modify firmware too.

The answer is not giving these companies money.

one day I'll divide them into subfolders

if a text file isn't good enough, or there needs to be an image embedded, I use other file types

IDK if we'll see that extreme.

We probably will see 40 Year loan Mods from FHA by EOY, they've been getting guidelines around those ready for some time. But that is a stopgap for borrowers that are falling behind, not for buyers hoping to get into a home.

If I had to guess any can-kicks will be more gradual. 'First time homebuyer' grants would be a good candidate for tweaks on things like maximum income. I spent much of my 30s in a weird spot where I was just out of the range of eligibility for such programs, and it would have made a huge difference.

> still 20%

PSA: You don't -need- 20% down. I will say, if it's anything other than a starter home, you probably -should- have 20% down. But the biggest mistake I made in my 30s was worrying more about getting that 20% than just getting into the game. If I would have gotten in back in 2016, I would have been able to refi into a conventional anytime between 2019-2021 and come out ahead.
I have a non-Apple TV that supports AirPlay and sometimes when I try to get my iPhone to play something on it while the TV is disconnected (completely off) it causes my ASUS router to drop the WiFi signal completely for a few seconds.

I have a feeling that the iPhone keeps searching the network and my router cannot keep up with the requests or something? Not sure but that's a theory I didn't get a chance to investigate

This is fantastic work - just had a couple questions about it:

1. I've heard different accounts of how well unity web GL is supported, did you run into any limitations?

2. What did advantages did wrapping this in Vue provide?
What I'm afraid of is that the people in my society with large amounts of money, power, weapons, and influence are acting like a bunch of sixth-graders.

I'm not asking for miracles. I just want the crazy to stop.
I wish I could tell if it was trolls, idiots, or villains - it's hard to respond appropriately if unsure. regardless, this is very sad to see on HN.
Yes. The Fed's low interest rate policy has been a huge tax on those prudent investors who held safer assets like cash and T-bills. At the same time, they maximally rewarded extreme gambling in the markets. That's why we live in world that somewhat resembles the 80s TV show "20 minutes into the future" -- all just crazy schemes and advertising plastered everywhere. Who knows what comes next.
That would be a really neat feature. I do run slurm on single nodes and sbatch with dependencies to emulate some of the effect you are asking for.

I've got bad news, I've been extremely unimpressed with my Macbook's so-called smart sleep. Literally the first day I brought it into work I went to go take it out of my bag only to find that it was too hot to touch. Neither selecting "Sleep" nor closing the lid for 30 minutes had convinced the fickle OS to enter a low-power state.

You know what Windows and Linux offer that Mac doesn't? A friggin' Hibernate option. Please, just let me have a button to power off my computer while persisting its state to disk. No, I don't want to have to shut down my computer every time I put it in a bag, that's completely ridiculous and an utter waste of my time having to reset all my tmux panes, vim windows, shell histories... what a UX nightmare. They've made a laptop that's a terror to actually take anywhere with you. Even when the "smart" sleep does (sometimes) finally decide to kick in, it invariably costs 20% of the battery.

When people say that Macs have good power management, what they mean is that Safari is optimized for power consumption relative to Chrome and Firefox.
Try using NextDNS on your tv. They have a preset list for Samsung that used to block the ads.
I remember the winner was Bob Lee's solution, which uses a doubly-linked list to represent digit sequences to support fast backtracking. Kinda a point that algorithm and design matters first and then language, as illustrated by the excellent war stories in Skiena's The Algorithm Design Manual.

If I faced this dilemma, I’d just turn on my phone’s hotspot, give the credentials to the TV, then turn off the hotspot after it’s updated.
> Saying it was a conspiracy theory is not in this case accusing them of lying.

The bottom of GP seemed to deny it happened or at least denied it caused harm to the nearby human population.

You are defending a position opposing that of the author’s likely intent.
No, but if you say you don't break API in minor, but you have a bug that breaks API, then minor broke API.
Reliable, meh. I've had two die on me. One lasted a few years of VERY light usage, the other died barely a year or two in. Also almost no usage.

In both cases it simply stopped appearing on the bus, but was clearly "running" to some degree - it would get warm to the touch, just as they normally do.

I've also found that the Thunderbolt connector's lack of a "click" engagement to be a serious issue for storage, network, and even display - every Mac I've seen it in use, the connection has been flaky. It really fucking sucks to whip out the thunderbolt adapter and plug into ethernet for "reliability", set up a transfer of a ton of data, and half-way though shift the machine slightly aaaaaaaaand then the ethernet adapter disappears and your transfer is fucked.

Happy to see them drop that idiotic connector for USB-C, as at least that has some sort of physical retention mechanism other than "hopes and dreams" (ie: rely on proper clearance tolerances between different vendors, on surfaces that will wear with use.)
My problem with that is, Apple doesn’t offer upgrade paths from n-2 to n-1.

You need to either remember to upgrade before the next major release comes out, or stockpile the installation image before it’s gone from System Preferences.

Fail to do either, and you’re effectively forced to upgrade to the just-released version against your will.
The micromanagement is implicit in your use of the word "you". "How do you know ... ?". Who is that "you"? If it's the person's manager, the answer is "because we talked about it in our 1:1 or on chat". If it's anyone else, the answer is either "don't worry about it" or "coordinate with the manager". It's good to have a plan for the week / month / whatever timescale, to help teams coordinate with each other, but you really don't need real time visibility into what a team is up to if you aren't on the team.
The problem is that usually those norms were dictated by some monarch because he had power and took the responsibility for that power and its consequences.

Now nobody is taking the responsibility, but we still have the norms.

In some cases I've offered to pay with the same outcome. Sometimes the offer to pay came after the initial email, other times it was in the form of cryptocurrency and others, I'm pretty sure, it was offered initially but, regardless, all of these cases might have had the framing of the offer poison the interaction from the outset.

My next experiment is to frame it in terms of a purely business transaction with the condition that the work released under a libre/free license, making sure not to use any of the passive language I've used before, etc. The issue is always understanding what a fair price is and, for my own personal standards, make sure the artist understands what kind of terms they're agreeing to (the equivalent of "informed consent").
The money printing far, far, far predates the present administration. It's been going on for at least 15 years, and many argue it started after the 1987 crash. The big question is whether this is finally when the music stops.
This is why large monitors are so expensive, because they aren't subsidized by the ads large TVs force upon their users for the most basic usage.

But if you can afford it, there are 40+" 4k and 8k monitors to which you can plug AppleTV/Chromecast/a small PC with a budget discrete graphics card. Or you can get a conference projector if no monitor on the market meets your size needs.

looks like this can be used to get free wifi on airplane
As weird as it sounds, $3000 machines still only come with one radio so it can only tune to one frequency at a time. Similar latency spikes happen when roaming between access points. WiFi is a mess and will be for the foreseeable future. Personally I just use a 10G ethernet card and some cheap optics.
Soon they will ship TVs with sim cards to track those hard to reach tech worker / drug dealer market

> Is our atmosphere more or less transparent to some parts of the frequency spectrum than others?

Yes. The frequencies that are not blocked are called "atmospheric windows". And there is indeed such a window for microwaves. These windows also exist for visible light and a range of IR, but those depend more on weather conditions.

I'm not saying withholding certain types of heavy weapons is good or bad, I was just responding to the person saying that Biden doesn't want these weapons to be delivered, which seemed a bit misguided.
Some BenQ projectors, including the just-released X3000i I recently picked up, consign the "smart" portion to an Android TV HDMI+USB stick that plugs in inside the body of the projector. I just never plugged mine in and the projector works fine.

I am no expert just a curious outsider, so take this with a large grain of salt, but it is my understanding that that’s one of the most pernicious misconceptions even in practicing psychologists, but that the current high quality research suggests the learning styles theory is flawed at best and wrong at worst. This article is ~8 years old but I don’t think anything has quantitatively changed the conclusions over the intervening years.

It's hard to find definitive information on this, but from what I can recall I don't think Samsung actually rolled out the current ad platform until mid-2019, and only in certain regions. So you might have been spared if you never updated your firmware or were in a region with no Samsung ad sales channel.
There is a very strong anti-vax contingent on this website. It’s unfortunate given that you’d think appreciation for science and healthy, well reasoned skepticism would come naturally for technical professionals. Guess not.

> All evidence from their own AI/AP team and presentations is that there is no real design and system validation going on over there. They're flying by the seat of their pants, introducing potentially lethal regressions in every update.

What is this evidence?

I've seen a few talks from Andrej Karpathy that indicate to me a more deliberate approach.[0] "Software 2.0" itself seems like an approach meant to systematize the development, validation & testing of AI systems, hardly a seat-of-your-pants approach to releases. I have my own criticisms of their approach, but it seems there is pretty deliberate care taken when developing models.

File backups need to be done in real time, otherwise backing up gigabytes of data on demand would be infeasible.

We recently released this feature for Standard Notes[0]. Files you upload to your account from any device are automatically encrypted and backed up to a local folder on your computer.

Granting companies full custody of your files today feels reckless; local backups are a must. And better it be encrypted.

There’s also going to be a non linear response. The sort of mid-tier luxury that one million can buy will be at the end of a chain of value added services and basic input goods, all of which are being squeezed by inflation costs. It’s also easier for luxury goods to raise cost faster than inflation as a hedge against future inflation
Funny to me that these are seen as novel concepts, and all over the comments are people going on about how this is so true for founders.

What about the workers actually building the product, making far less, and probably putting in more time. Why is the issue of their valuable time compared to money almost never discussed.

We all only have one life and ot should be able to be enjoyed. Why do we always forget the pursuit of happiness, except as it applies to the upper class.
Terraform not written in Go wouldn't have existed. If it relied on a JVM or Python/Ruby interpreter being present, at the correct version, it never would have gotten as popular, and if it were statistically compiled C/C++ it would have never gotten as far and as quickly.

Go offers a nice balance between performance and platform agnosticism, features like parallelism without it being too complex to write. Manual memory management would have been a useless obstacle wasting developer time for little real gain. Fighting the language to have parallel execution, easy crosscompile, etc. why?

As for HCL, I'm on the opinion that a DSL is better. It's even in the name, Infra as Code, not with code. You want your infrastructure declarations to be easily readable and supportable. Anyone who has used Terraform can read any HCL; your Python code doing the same could be terrible and unreadable by anyone not already on your team. Too much flexibility for something as critical can end badly, imho.

In any case, there's cdktf now, you can mix and match terraform with cdktf.

Samsung owns up to mistake after using iPhone photos in promotion
At 20 years old, you don't need to invest, you need to level up.
First, USB is 5 volts.

You will likely need minimum 3 of the solar cells in series to generate near 5V, maybe 4.

Then there is rate of charge, minimum worthwhile is probably around 250mA, maybe 500mA depending on what you charge.

Based on area and efficiency, eBay lookup, a 54x54mm solar cell is quoted at 2V, 100mA.

So allowing for efficiencies of conversion etc, then you need 3 series, 3 parallel of these cells to get close, running direct in a buck/boost convertor to make steady 5V 250mA under as wide a range of conditions as possible.

Maybe something like this https://m.alibaba.com/product/60841019812/DC-6-24V-12V/24v-t...

Though you might want to run more cells/voltage into it to maximise economy.

So a standard laptop USB port does 500mA, so you are looking at maybe 18 solar cells to replicate one laptop USB port capability.

Plus a one dollar part, and wiring and mounting.

So at $1 a solar cell capital cost that is around $8-10 per watt. (5 volts X 0.5A is 2.5W, $18 worth of cells, roughly).

If you go to AliExpress and buy any decent sized solar panel you can get them for under a dollar a watt.

If you buy the raw cells themselves and assemble them, because you have more time than money, under 25c a watt, maybe down towards 6-7c a watt - https://m.alibaba.com/product/1600163540077/Cheap-5BB-Polycr....

Interesting project, but totally uneconomical.

Edit, fixed up my costs in the starter config of 18 cells for 5V 0.5A
A thing they seem to go out of their way to hide:

TCL + Roku TVs (and probably other models?) have one physical button that you can use to turn on and off and change inputs. It's well-hidden, under the center logo.
> pico instead of nano, zsh instead of modern bash

nano is a GNU clone of pico. pico is OG nano.

bash was replaced with zsh because Apple purged their OS of all GPL3 software (including nano).
Touch Bar was an absolute failure on every level, thankfully Apple backtracked on it.
Our culture is to praise in public and criticize in private: proceeds with 16 bullet points worth of public criticism.
Having your paying customers act as alpha testers, for software that can potentially injure and kill other people, is imho not exactly the kind of "innovation" we should strive for.

There is simply far too much housing inventory for companies to own absolutely everything. There is also the prospect that if prices climb so high that the middle and lower class residents are priced out, homeless encampments will take over absolutely everything, while unoccupied inventory slowly deteriorates. I am not a market analyst, but if you look around even at some of the most prestigious retail neighborhoods, the effect of engineered inflation on the housing market has already displaced so many people that even the wealthy are not safe in venturing out to shopping districts and nightlife spots.

It's a self defeating cycle that needs to be reigned in. No matter how many fences people build around their homes, and how much security they hire. If the majority is forced into desperate living situations, they eventually revolt and redistribute wealth.

It is really government's responsibility to reign this in by lowering income taxes, taxing the rich and corporations properly, by reinforcing fair wages, and in many other ways, but even people in those positions of responsibility are asleep at the wheel of accountability, and also lining their own pockets.

Eventually, we as consumers need to stop contributing to these cycles of hysteria by not buying those overpriced homes, and working to develop the communities we're currently in. Individuals need to avoid greed impulse as landlords and stop dramatically raising rent and for companies to prevent artificial price inflation too (gouging), understanding that it will create a better eco system over time for us all.

Globalism of information and companies has led to harmful results in many ways, it has also driven us to a point where price controlling monopolies have far too much power, and too much overhead to keep costs down, and to keep world-wide distribution and value up for goods reliably.

There are literally thousands of overconfident investors now (many faking success and many that inherited their wealth) sitting on vacant properties, failing companies, and losing money on business ideas, yet posting about their extravagant lives and fake symbols of their business skill along with terrible investor advice on social media.

Along with Crypto, NFT, and investment scams that are regularly promoted by big industry, this drives the greed and ignorance that in turn affects current investment and ultimately business failure. We need to call this practice out, or face experiencing the market chaos and even deeper crashes that will indeed come.
This. The biggest risk factor for cancer (to my knowledge) is accumulated cellular damage.
DS displays are built better, yes (usually, they get the top yield of panels with the target resolution and in outdoor cases also stronger background lighting). The real difference however is the explicit guarantee that there will be support and spare parts available for anything from 5-10 years or that there will be at least a mounting-compatible successor model.

Since noise is usually not a factor to be considered, they are also usually built with much bigger temperature profiles in mind than your consumer indoor TV (e.g. by using cooling fans or heating elements) so they can work just as well in -20 °C in the winter or at 80 °C in the summer heat.

Also, some of these offer features that consumer displays do not offer:

- YUV or SDI inputs

- RS232 remote control / status monitoring

- especially in zero-bezel modules: support for grid processing. Basically you have a HDMI/DVI/SDI input and a loop output, and you daisy-chain the whole bunch of displays. Then you tell each of them to slice and upscale just a specific part of the picture.
Show HN: The Amalgam Engine – Easily create isometric virtual worlds
There's more than enough evidence that macroscopic biological entities use processes that depend on qm effects. See for example photosynthesis or enzymatic reactions.

As I understand it, the wave collapse is wholly probabilistic and there's no "hidden data" (hidden variable[0]) that we could now to predict the outcome. At least not if we want keep expecting locality.

[0] https://en.wikipedia.org/wiki/Hidden-variable_theory
Hey all, Net_ here.

Virtual worlds are really important to me. They've helped me through a lot of tough times, and I think they're a necessary part of our future. Unfortunately, they've largely been stagnant for the past 15 years. This is my attempt to push the needle forward by providing developers with an open-source engine to easily make their own.

This is a sprite-based, isometric-only, single-server, non-instanced engine. I'm keeping it very focused so that we can make the workflow as streamlined and joyful as possible. The full project will eventually also include a chat server and user account management.

A simple demo world is available to play around with, just download and run the client: https://github.com/Net5F/Amalgam/releases/latest

It's still very early, but the netcode and engine architecture are in a pretty good place. I have two network load test scenarios that I'm benchmarking against: 150 clients in 1 area (video link in repo readme), and 1000 in groups of 10. Even on modest hardware, there's plenty of headroom available for adding more features. Still to come: NPCs, items, interactions.

Load test results (Linode server, $30/mo, 2 - 2.6GHz):

Scenario | Bandwidth usage | Average CPU usage (200% max)

150 in 1 | 1.66MB/s | 25%

1000 in 10 | 1.31MB/s | 76%

I welcome all feedback. The project has a long way to go before it's really useful to developers, but I figured I should get over my nerves and start showing it.
