I won't hear of it. Matlab is great. Superb at manipulating matrices, great for getting started with differential equations, world-class plotting library, and massively forgiving. All the things a computational engineer like me needs.

I would never use it for producing software meant for distribution, but people mainly hate on it because it's 'cool', without realising that it excels at what it does. I fucking love matlab.

I can see we are at the "you're being mean to me" stage in the discussion instead of the "I should not spread misinformation then doubled down on it" stage. No one is abusing you and you aren't a victim when someone wonders why you're misinforming people. If what you are saying doesn't add up (temporal chicken and egg, partial location information etc), focus on that instead of attacking people that are giving you the feedback that what you are saying doesn't add up.

You originally said that a server would have to render the game and use the z-buffer to do any occlusion culling, but this is not only not correct, it is contradicted by something you yourself linked. Why not just admit that this was a guess and not from experience or research into how game engines work?

"But even that's not quite good enough "

You are the only one saying that. Going from seeing every player on the map all the time to only seeing players a few frames before you would have seen them anyway is a huge leap, which is again, what people are talking about and exactly what you linked.

"should the client really get the full location information? "

What partial location information are you envisioning here?

Again, focus on backing up what you originally said first instead of trying to shift the goalposts from how servers would "have to" do occlusion culling.

> can do any improvements I want, when I want

This is the main thing I'm wondering about. Most people I know who own homes enjoy working on them. Home improvement becomes a hobby that they like, whether it's basic plumbing or painting the walls or building a deck. I despise this work (even though I do basic carpentry), and I fully consider it work that detracts from my life. It's like doing the dishes, it's a chore, and often stressful. Is owning a home worthwhile if I have no interest in these things? I do have great interest in privacy, not answering to a landlord, and not being priced out of an area.
Are you confused that a “question” can be a hate crime? Seems pretty straight-forward to me?
Nice! I thought about doing this last year - I wanted to be able to identify birds as well - and count totals for each species. I believe it's possible at a DIY level, but would take some effort.
it only seems unlikely if you don't understand how covid works. covid-19 is an airborne illness that is passed through moisture between humans. humans radiate moisture when engaged in activities that increase heart rate. protest involve a lot of marching and yelling at each other, which, spread moisture through droplets, perspiration, breath etc. many protestors were mask averse, to put it mildly. so, no, not now known to be relatively safe right?

Why? Each flight produces an amount of carbon that could be removed from the atmosphere by about $20 of carbon offsets or $1000 worth of carbon capture. Finding a greener fuel would be a really bad allocation of engineering resources.
Tell HN: Don't leave candidates without reply
Hello everyone,

Most of you already know this, however, if it's a food for thought or a reminder for at least one person, it's definitely worth it.

• Please, never leave candidates in recruitment process without reply. •

Recently I had an actual pleasure interviewing with quite young and promising startup. Four meetings with three technical founders. Great moods and immediate, positive, mutual feedback. Last one ended with “We’re going to debrief today and let you know what the next steps are”… and then nothing.

Personally, I don’t mind. It’s more of a red flag for me than disappointment. I’m also 100% OK being rejected as I understand that with such a small team, even purely personal, vague hunch is enough to make such decision. By now, as probably most of you, I’m also confident enough in my value that it doesn't affect me directly in a negative way.

Not everyone is in a such fortunate position though. For people at the beginning of their careers and those struggling with self-esteem for any other reason, this can be literal torment. Getting a decent job, they’ve spent a lot of time preparing for, is such an important foundation that everything else is on hold in their life until that happens.

As a friend, partner, or a mentor, I’ve rode a passenger seat of weeks-long roller-coaster rides from excitement to doubt. I’ve witnessed months of stress from being stuck in a limbo. I’ve seen last bits of self-confidence being completely stripped away and depressions deepened when no reply hits as “I’m not even worth a short email”.

It doesn’t have to be complete lack of response and reactions don’t have to be so severe. Yet, while from a company perspective recruitment process of a single person might start and finish within half an hour, on the other side it could be even years of rejection.

I’m not asking for charity and it shouldn’t affect actual hiring decision. However, on behalf of those that don’t have their voice in professional environment yet, I’m pleading for •compassion•. Simply by keeping them as informed as you can, as promptly as you can.

For you, the recruitment team in your company, or anyone else in your network, it might be a minute of effort to write “We’ll get back to you by the end of next week” or “Unfortunately, we decided not to move forward”. For the recipient, simply knowing where they stand can make the biggest difference in the world.
Knowing the answer is 7 isn't a spoiler. The point is to work it out. You'd have to click the URL and see the WA input to be spoiled about that.
The previous owner of mine installed a new water pump at 80k miles, and I did it again at 150k. Similarly don't have to change the coolant because the coolant expansion tank will break in 5 years time. (the corner is plastic and can't take the pressure.
Thanks. I’ve only had time to skim-read it, but even this is already five times better than all the news articles I’ve seen combined.

The style and the first three pages definitely explains the differing reports, in particular the beginning of page 3.
+1 on this. Matlab toolboxes are much more well tested, has thorough documentation and work much better out of the box, especially for controls and signal processing. Working with scipy can be a pain sometimes with incorrect or unstable results.

Assume he paid cash. If he had instead invested $200k in the S&P 500 in 2011, his account would be worth ~$756k today. So he essentially paid $256k, or roughly $2k/month, for housing over 10 years. If he could have gotten a similar place for an average over 10 years of $2k/mo, it's breakeven. That's before paying property tax but also before writing off interest & tax.

Although this ignores the fact that you can make what's essentially a $200k investment with only $40k, and you still have to find a place to live - and the rent is virtually guaranteed to go up -- if you go the S&P route.
>Whereas you can easily call and have it fixed within 5 hours if you owned it.

The caveat with these sorts of fixes is these service companies will sometimes upcharge a big fee for "emergency work" to have it fixed within 5 hours rather than in two weeks. I literally had water shooting out of my ceiling and the property manager admitted as much to me when I asked why the owner left me without water for days.

There are plenty of other good examples.

Try this one: https://www.the-scientist.com/features/the-surgisphere-scand...

"It sounds absurd that an obscure US company with a hastily constructed website could have driven international health policy and brought major clinical trials to a halt within the span of a few weeks. Yet that’s what happened earlier this year, when Illinois-based Surgisphere Corporation began a publishing spree that would trigger one of the largest scientific scandals of the COVID-19 pandemic to date.

"At the heart of the deception was a paper published in The Lancet on May 22 that suggested hydroxychloroquine, an antimalarial drug promoted by US President Donald Trump and others as a therapy for COVID-19, was associated with an increased risk of death in patients hospitalized with the disease."

They completely fabricated the data.

To hurt Trump.
lol, yee, yes i did mean $4k; and no, hard enough to even get me to consider selling for a newer car, much less for its value or less.
> This is dangerous, but if well documented and understood it might be okay.

I agree in principle. I think even something like std::unique_ptr could work; the concern would be self-referential types. Notably Rust doesn't allow those anyway, so I think any Rust type would be fine, not just Copy types.

> Then there is the fact that you basically make every insertion 3x as costly. You better have a good reason to need this given the additional complexity and caveats.

Still might be a lot better than a linked list for small types (due to less RAM spent on pointers and better cache locality because it's contiguous). With the exception of intrusive linked lists of stuff that is separately allocated anyway, I really hate linked lists.
Just to clarify. A investor - > founder relationship can be very stressful. One side holds the money and lifeblood of your company over your head. And the other side holds the money and investment hostage to operating practices and reality.

For investors this may be extreme stress they can't just bow out of.

So yes, not literally a marriage but extreme stress is still extreme stress.
Ask HN: How do you make money on the side?
I was on a work visa in the US for the longest time and wasn’t allowed to earn anything outside of my paychecks. I just became a permanent resident and so have a lot more options open to me.

I don’t want to build the next hot startup, make a billion dollars or anything of the sort. I have a great job and my employer is pretty cool about moonlighting as long as there are no conflicts and it doesn’t affect my work. I want to commit 1-2 hours a day and some weekends — all from home — to try and build an alternate income stream, partially for the experience and partially to earn some “fun money”.

I am skilled in all things tech and programming, but that’s about it. Has anyone had any luck in this area, or have stories to share?
"The words 'people of the United States' and 'citizens' are synonymous terms, and mean the same thing. They both describe the political body who, according to our republican institutions, form the sovereignty, and who hold the power and conduct the Government through their representatives. They are what we familiarly call the 'sovereign people,' and every citizen is one of this people, and a constituent member of this sovereignty. The question before us is, whether the class of persons described in the plea in abatement compose a portion of this people, and are constituent members of this sovereignty? We think they are not, and that they are not included, and were not intended to be included, under the word 'citizens' in the Constitution, and can therefore claim none of the rights and privileges which that instrument provides for and secures to citizens of the United States. On the contrary, they were at that time considered as a subordinate and inferior class of beings, who had been subjugated by the dominant race, and, whether emancipated or not, yet remained subject to their authority, and had no rights or privileges but such as those who held the power and the Government might choose to grant them."
Not me. Are you responding to parent poster?
The idealist in me thinks it should be legal, as what people should put into their bodies should be there choice.

The pragmatist thinks it should stay illegal. We know it’s bad for people’s brains, especially developing minds. That’s compounded by the fact that many people think the primary danger from drugs is death, and since it won’t kill you it must be basically harmless.

I’m sure a good portion of us also know people that have become psychologically addicted to it and have wasted a good portion of their lives. I have friends that didn’t do any pot until they went to a state where it was legal, and they decided they liked it enough where they risked bringing some back with them. It seems clear legalization will lead to increased use.

In short, it’s a battle of individual rights vs. what’s best for society. I’m not sure what the answer is. It also seems like a slippery slope - if weed is legal, shouldn’t most other drugs be? If that’s the case, should prescriptions still be necessary for things like stimulants?
A linked list needs a pointer for every piece of data. If the data is small, this will also be a 2-fold memory impact. Plus impacts on cache coherency.
They pay for bullshit research all the time. It comes from the advertising budget instead of the development budget.

This may not be well-known, but archive.org can and does remove pages / sites from the archive. Authors can request this, site owners (separate from the authors) can request this. There may be others who can request this.

Interesting. So was this a supplement to math learned at school or was it the primary math?

I looked at that problem after posting my original and was utterly confused. Would you trust yourself with an answer involving half-pennies? Seems like an error. As others pointed out, in #1, unless the kopecks are integer, the answer is underconstrained. #2 requires non-integer kopecks.
5% is not not 3x the median savings balance of families seriously trying to buy a home. That’s setting aside that lower income families tend to live near lower priced homes.

Lower down payments meaningfully increase access to real estate. It matters hugely to be able to accelerate purchase timing by years, or decades.

Depending on your circumstances, it may not be possible to seriously consider it, but another alternative to rent-vs-buy might include various van/camper/coach options, which can be parked for months at a time at "seasonal" campsites, often for $500-1000/month.

Obviously equipment like this isn't going to appreciate either, and you'll be subject to all the same maintenance costs of owning, so in some ways it's the worst of both worlds— but it may still be cheaper than trying to rent if you can't or won't enter the market right now and mooching from family isn't an option.
Yes, but if you make an offer contingent on bank financing, and someone else makes an offer contingent on nothing, which offer would you choose as a seller? Guaranteed money now? or probably getting money after the bank completes their paperwork? Many people selling a home already have another home somewhere else, and they're not interested in keeping around another empty house to make payments on.
LE limits the number of subdomains you can request on a given domain, so it is probably somewhat necessary to use wildcard certs.
> I believe they are making the case that fetishistic hoarding of historical documents is...in an of itself an aspect of western/euro-centric ideology and its propagation through colonization.

I'm pretty sure a historian with the right background could easily find examples of that in, for instance, China before it had any significant contact with the West. Trying to particularize it seems incorrect.

> I believe they are making the case that fetishistic hoarding of historical documents is both, only available to those with a means of wealth created through probably exploitation...

That's probably true but well understood. Caring about historical documents, let alone hoarding them, is quite a luxury activity available only to those with wealth, and wealth (now, and especially in the past) usually comes from some kind of exportation of others.
> What people should be looking at is the crazy amount of Israeli presence in the so called cyber security sector.

Limiting the ability of nations to export this kind of capability as a product for other entities to use is precisely what "trade ban" would do.

You're right that a trade ban won't affect the ability of nations to develop and deploy their own spyware, but most of the targets in the Pegasus dump seem to be of people peripheral to smaller governments that don't have this kind of capability themselves (which is exactly why they buy it!).

Pretty much. Every EVIP (emergency vehicle incident prevention) course preaches this. The advantage to lights and sirens and opticom (the traffic light changing technology) is minimizing stop and go, and optimizing flow of traffic in your direction. They demonstrate that an extra 20mph on your average response, which is likely less than 3 miles (if not quite a bit less), and not much more than 5 until you start to get more rural, is likely only to save you seconds - and there's very very few things where an ambulance arriving literally seconds faster makes a difference in patient outcomes.

But it does slow your reaction time, and it does massively increase your accident risk. And that's couched in, "And now it's going to take many many more minutes for another unit to get to your patient than the few seconds you'd have saved".

Sadly, most people when hearing this will prefer to argue to the death to support their "choice" of ${favorite giant corporate product} and try to tell you "you're just being paranoid". We live in a world where a great many people will accept the most outlandish conspiracy theories as undeniable fact with little to no supporting evidence, but when you try to warn them about real and verifiable concerns, it doesn't matter how much proof there is… You're automatically wrong in their eyes. What's more terrifying than that? Some of those people hold positions of great power in this world.
How about this: a service that runs on a customer’s own domain, under a subdomain. Think blogging, GitHub issues, some kinds of SaaS products. Seems like something not covered by wild cards that would not be thwarted by LE rate limits and probably is useful in practice.
Suppose you’ve got a 16 foot strand of lights and an 8 foot column. If you unwrap the column in your mind, you can see you’ve got a right triangle with a hypotenuse of 16 and vertical leg of 8. What’s the angle that the hypotenuse makes with the floor? It’s the angle whose sine is opposite/hypotenuse = 8/16 = 1/2. That’s 30 degrees. So wrap the lights around the column at a 30 degree angle and it’ll be close (with a bit of slop thanks to rounding corners on the column).
