But in this case the moral of the article is exactly the opposite - if you throw out the irrelevant information the answer becomes trivial (no need for your calculations).
Learning ML by doing a personal project
It is just a hash map with a few common functions defined; hash maps are occasionally useful, but what is all the praise about?

The mentioned "simple" bit is arguable: as a language's building block, a hash map is relatively complex and specific, since those can be built out of lists (or trees, though lists/arrays may be preferable for efficiency), which can be built out of pairs (product types, cons cells, tuples; unless going for that efficiency, though it can still be pretty efficient with trees). Maybe it is one of those "simple versus easy" mix-ups.
People always like to figure a conspiracy. It is very unlikely Spotify is optimizing their discovery for profit. Their algorithm is one of their primary selling tools and while it isn't unheard of for brands to fuck their goodwill to increase profit, I just don't see it happening here.
Stallman is correct when he says that "free" and "open source" are synonymous. They reflect different philosophies but the same set of licences.
What is the expected range of this thing? How far can it communicate?
It isn't open source to anyone, by the universally accepted definition of "open source" that has obtained for decades.
Wow. The new passport is a work of art. I'm sure many of the extra features are to help prevent counterfeiting, but they've been executed beautifully.
You'd think some retailers would create some incentives. If a consumer is consuming below expected at a time when the retailer is losing money on every watt, the retailer should split the savings with the consumer to incentivise the behaviour.
I assume that you incur the cost once and amortise it over the life of the photo/painting.
You're figuring that the universe is non-deterministic. If so, yes, this would be a more difficult problem.

If the universe is based on some solid deterministic rules with a fixed seed value, then it would work.

Quantum events appear non-deterministic, but that might just be because we don't have all the answers right now.
That is about latency, but Amdahl's law is about throughput I think.

What are the chances that a similar procedure could repair the optic nerve from damage caused by glaucoma? Seems within reach but maybe the complexity of the optic nerve makes it a whole different ballgame.
Does anyone know why they used bubblesort in the first place? It is known for its bad performance, so what other factors came into play? Number of ops, maybe?

Hey HN, is there any web based equivalent GCompris?

If not what would it take to build a architecture for web app like that? Where individual contributors can publish their games.
I'm on a Banfield membership plan for my dog that's like $50/mo after tax, so $600/yr. The plan comes with routine checkups with some basic lab work, "member rates" at their nation-wide clinics for any non-routine care, all shots included, and one dental cleaning a year. So even if the cleaning was 90% of the cost (I imagine its probably less) that's like $540/yr.

The dogs we had which we didn't do dental cleanings, their mouths were often in pretty rough shape by the end of their lives. Even with us trying to brush on regular schedules and giving good feeding, our geriatric dogs would often end up with lots of bad teeth in the final years of their lives. Meanwhile the dogs we've had which we've done yearly cleanings pretty much never had oral issues throughout their lives even well into very old age. Just my own personal anecdotes, but unless I see something reputable to change my mind I'll probably continue on yearly-ish cleanings.

I definitely do agree its probably way too much stress on a cat though. We did one dental cleaning with our cat and decided it was way too much stress on him and decided we wouldn't do another cleaning unless something got really bad. He's lived just fine without any dental issues for over a decade since that cleaning, so I imagine its probably pretty unnecessary.
One thing that always bothers me is time dilation when it comes to observing distant objects like this. If it takes 4 light years for the light to travel one way (and the one way speed of light still hasn't been measured!), that is for the observer at the origin, the photons we observe, for them it is much less than 4 years, is it even in years? So if I look at alpha centauri with a telescope, it isn't really aloha centauri 4 years ago that I am observing right? It's much more recent than that?

Otherwise, if a 30yo person travels at the speed of light from alpha centauri to earth, when the person arrives will they be a 31yo(~) person who arrived 4 year later, effectively time traveling to the future? And if they return right away, will folks at alpha centauri meet a 32yo(~) person who came back 8 years later? If so, then maybe superman had the right idea about flying really fast around earth to travel in time, just not to the past.

Perhaps some billionaire will decide to spin around the solar system really fast for a few decades and skip a century or so? Haha!
Whether he's a genius or not - or a leader of the incels - it seems like the standard ways of evaluating decisions should apply to him. It's strange to evaluate a decision before considering the motivation behind the decision.

That's what I meant. Even if you imagine a scenario you can successfully predict (a cashier handing you your change, for example), how it plays out in experience is always different.

Anxiety causes you to imagine how a scenario would play out, in detail. Flashes of things going wrong, something breaking apart and all the terrible things that a horror movie director could imagine.

According to the Twitter thread linked, at the beginning there were only 30 items, so using bubblesort didn't matter. The number of items has since grown to a thousand.
There are a couple physical principles that work together to limit solar thermal collectors: heat flows from hot to cold, and mirrors and lenses work both ways. Together, they imply that a solar collector can't heat up anything hotter than the surface of the sun because if the target was hotter than the sun, it would heat the sun up and not the other way around. The surface of the sun is 5.7 thousand Kelvin. This is enough to melt, but not boil tungsten, which I must imagine is a major issue for the tungsten gas industry.
Yes I remember being surprised that Linux containers were used for that purpose.

Unfortunately pretty much every action you mention kinda smells like a way of avoiding direct rejection.

Coupons, booklets, degrees, certificates, and networking are not sales.

(Neither are designing a logo renting an office and printing business cards, in case anyone wonders).

No amount of competency can compensate for a lack of sales. No amount of credentials, either.

Sales come first. Before everything else.

If you aren’t selling your business is dead.

Good luck.
have agoraphobia pretty bad. I've spent so much time trying to work on exposure, but then I'll have a huge panic attack, I don't have access to my frontal cortex to reason through it, during this time I'm feeling the immensity of the universe, I feel electricity running through my body, at the end of it all when I get somewhere "safe" I'm not able to think straight or sleep well for months. So yeah the impulse to avoid those feelings is pretty strong. I'll push myself once again in the future but the risk reward ratio is pretty bad. Thanks brain wiring!
Very OT, but I concur. I need a DSP for my car audio system. I considered a rpi3 with a DAC attachment.

I tried the raspbian OS with some moderate overclocking and removing unneeded startup processes. Couldn’t get it under 25 seconds for boot. Kind of a deal breaker (remote start unit could help, but…)

Apparently somebody can start the rpi3 in <3 seconds. I’ll believe it when I try their image myself. Their setup disables USB and networking (maybe audio too who knows) which is a giant pain for configuring my system.

Maybe I’ll try again with an RPi 4 and usb3 nvme. or maybe I’ll just pay hundreds of dollars for a dedicated DSP unit.

In case anyone cares, my main use case is parametric EQ for phon adjusted low bass frequencies. 90dB 20Hz sounds as loud as 70dB 50Hz (give or take) and subwoofers are generally quieter at lower frequencies. Hence, audio processing unit to cut as you go higher than your lowest decently loud frequency.

The lowest cost option for this is about $230USD plus some electrical components (miniDSP 2x4HD). I figure the rpi would cost around $100 including the DAC unit, open source audio software, just need some power source to link the battery to the rpi power cord.

Edit: I don’t want to spam thanks comments for helpful replies, so I’ll just say it here (possibly in advance): thanks!!!
Wild that people have accepted a 5000ms delay between starting their car and seeing behind them.

I suppose I'm more sensitive to downtime than most - I recently (unsuccessfully) tried to add a ton of capacitance into my head unit's power supply and acc-signal lines to keep it from turning off for a few seconds when starting the engine.
Some days you have to find motivation and some days motivation finds you.

Either way, it's because of your actions.
You are OK. Not everybody has a roadmap for their future at your age.

I pretty much agree with your conclusions from working through different scenarios.

Take a good look at the "esoteric" topics that interest you. Is there a common thread, e.g. bio-engineering? Think back at when you were young, what did you enjoy doing the most? What were your hobbies? When you step back and look at such questions and your answers you will see a common theme. That is the gist of the idea for where to direct your interests. Then based on those interests you will identify the area in which you might enjoy working.

Over time your interests will change and it is perfectly Ok to change careers as you go along.

If none of that jells, then consider taking a year off to work as a builders' laborer. The fresh air and physical work will clear your mind far better than sitting in some grad course lecture.
I disagree. I'm agreeing with the basic assertion that the future looks grim but that it is ultimately unknowable. As such, putting work in into improving those possible outcomes is better than hopefully preparing for their eventual outcome.

In any case, I'm at least suggesting _a_ course of action.

I'll have to watch that video after work; but from watching about ~30 seconds it seems like he may be equating capitalism to a malady of some sort (something that needs treatment); it's an interesting theory that reminds me of a group of people that quarantined individuals that were angry so that they didn't end up "infecting" others (which I can't find at the moment, but will look up later).
For the unaware, this quadrascan drew vector graphics by aiming the electron gun only where lines needed to be.

This meant most of the screen wasn't illuminated most of the time (think LCD vs OLED). This is why long exposures like this are possible and super interesting.

> You need your backend to focus on something, otherwise it would be focused on nothing/everything. You need to tie yourself down to use cases, otherwise every use case is your use case.

What I was saying is that your backend will now do what was doing before AND also will need to handle UI elements and relation between them.

So you have duplicate data architecture/knowledge in UI:

- once in FE as it needs to know the data architecture

- again in BE where it also needs to know what data structure UI needs.

Thus it couples FE and BE together around key names, JSON structure and moreso on information architecture from UI concepts.

I am not saying you should not do that. Maybe it works for you. I would not do it.

For me it will be like saying in a traditional simple HTML app that I should name tables and columns in DB as they are in the UI. Maybe some might coincide but that will not be an architectural constraint when thinking the DB.
If publisher accounts can be billed by the payment processor every month instead of every transaction and processor charges based on a percentage of monthly transaction.

I feel this is a business negotiation instead of a tech issue. But then I may be just clueless.
I don't think you can set aside universities when you talk about open source - they were the original drivers in this field, and continue to be heavily involved. The biggest difference is probably that most of the software written at a university is done by faculty and grad students and isn't work for hire, so for someone like me there's no reason to ever ask my employer to execute a CLA.

But the same problems arise in most other organizations - it's hard enough to get a legal department to sign essential things needed to keep a business running, never mind signing some random CLA for a project they haven't heard of.

Finally, your view seems oriented to pseudo-open source projects where someone slapped an open source license on code written at a single company and wants to keep control of that code within the company, rather than open projects spanning multiple organizations, run by the developers and architects of the code.
A long 1" black pipe on the roof can provide plenty of hot water in summer for showers.

By the way, pipes are one of those things that are both metric and imperial in metric countries. We have two different series of pipes here in Italy, one with 1/2, 5/8, 1, 1 1/4 inches and one in millimeters. Gardening leans toward inches and those sturdy black plastic pipes are at least 1".
Usually when rebrandings are actually successful they are more about hiding whatever came before. This is very hard to execute well though.
One extremely successful example is Musically -> TikTok for the international version of Douyin.
Musically had a very bad reputation and TikTok was able to start cleanly and operate without that scrutiny for years resulting in it becoming mainstream.
> Surprisingly, these particles were found decades ago by Alonzo Church, the inventor of Lambda calculus long before electronic computers even existed!!

John McCarthy has introduced his lambda notation in October 1958, being inspired by the work of Alonzo Church, but it had very little to do with Lambda calculus.

The essential innovation brought at that time by John McCarthy to programming languages was that, unlike in earlier programming languages like Fortran, where a function definition was a separate section of a program source file, where an identifier had to be bound to a function definition, a McCarthy function definition behaves just as a constant value, very similarly to a character string constant, integer constant or floating-point constant, so it can appear in any place where a constant can appear, it can be assigned to an identifier, but it can also be used directly as an argument in the invocation of another function.

Once the new semantics of a function definition was established, the syntactic notation for it was a minor detail. A possible notation would have been to enclose any function definition in a special pair of parentheses, like a character string constant that is enclosed in quotation marks. Because this was not feasible due to the limited character set that was available, the chosen syntax was that of a LISP special form, which needs a keyword, for which the choice was "lambda".

To distinguish in a function definition the parameters used for function invocation, Alonzo Church had enclosed them in a pair of special parentheses, where the leading parenthesis was a small Greek lambda character and the trailing parenthesis was a raised middle dot.

This provided the inspiration for the "lambda" keyword. Perhaps McCarthy was also inspired by Church's work to change the handling of function definitions to be like that of any other values, but that is the maximum extent of the relationship between Lambda calculus and LISP.

Nevertheless, the LISP "lambda" notation played an important role in attracting attention upon the work of Alonzo Church, so in the following decade there was much research in functional languages that was much more strongly influenced by Lambda calculus than LISP was.

I feel the same way about pursuing CS instead of Physics. But at some point, a pragmatic solution had to be made. So don’t go hard on yourself for that, you probably would have felt the same way about CS too.
JSON is far simpler because it has no namespaces and no entities.

But I think complexity is always 90% culture. It's pretty arbitrary what kind of culture grows around a particular technology.

If someone has at least one boy, it is 1/3

If they then say, I have a secret child-ordering X, such that the first in this ordering is a boy, I guess it is now 1/2

However the receiver of 1/3 case knows there exists a secret child-ordering where this is the case.

Weird!
If you're suggesting that medieval witch-hunters may have been acting irrationally, I won't argue. Anyway, this isn't my hypothesis, it travelled around for awhile talking about supposed discoveries of ergot in soil samples. The Salem witch museum has come out against it[0]. A quote:

"When considering the question “What caused the Salem witch trials,” it is important to remember there is a danger in seeking the elusive, singular, all-encompassing explanation."

IMO a big part of it is likely the desire to 'explain'/'rationalize' misfortunes in some way, that suggests a 'solution'.

Maybe it’s different for different people, especially ones in different generations? As in older generations tend to favor face to face, and different activities for different locations. I don’t feel that totally applies for the younger generations because the internet arrived during our formative years.

Personally, the only time gyms were effective for me was when I was forced into the office.

Now, my productivity is greater working remotely, and so is my discipline when it comes to working out at home. Probably because I have more time to do things like sleep, where normally it would get eaten up by a long commute.

The only real pro that I see for going to the gym is to meet new people.

From Wikipedia[1]:

Together, LoRa and LoRaWAN define a Low Power, Wide Area (LPWA) networking protocol designed to wirelessly connect battery operated devices to the internet in regional, national or global networks, and targets key Internet of things (IoT) requirements such as bi-directional communication, end-to-end security, mobility and localization services. The low power, low bit rate, and IoT use distinguish this type of network from a wireless WAN that is designed to connect users or businesses, and carry more data, using more power. The LoRaWAN data rate ranges from 0.3 kbit/s to 50 kbit/s per channel.

"ceased to exist" ouch. Guess I was holding out a small shred of hope that the chandrayaan-3 crew may be able to save the Roscosmos.

At least that turn of phrase makes it sound like the death was quick and instant.
At the same time, as someone very prone to this kind of behavior, with siblings with similar issues to talk to, we've all found that few attempts at helping are more frustrating than being told "just remember that you don't need to be anxious". The entire point is that in the moment that just doesn't work. It's kind of like telling a person with ADHD to just pay attention.
I have to agree here - including pinecone in the images of major competitors but doing absolutely no analysis of the product is bizarre. I would expect almost everyone would come into the article aware of pinecone and pg_vector, and often just at a “it’s a leading vector database but that’s all I know” level. It leaves a giant question mark in my mind of how pinecone fits into the space of competitors. It’s absence (beyond an image with its name called out) is baffling.

I am also a bit surprised at the hostility to the pinecone employee here. I see a bunch of other companies and projects jumping in and everything is cool. But for some reason the pinecone dude catches a lot of grief.

What’s going on? Is there some weird toxic subculture in the vector database space that’s got it’s knives kit for pinecone for some reason?
