There's a difference between government acting as an interested customer, vs government subsidizing something for political reasons.

Government should not be just handing out money without getting at least that much value back. Government may very well hire a company to do something because it's more cost effective than DIY.
In an organization with hundreds, possibly thousands of people, how would you get human-defined standards to be applied evenly when other people are actively existing in the grey area between what is and is not okay? Eg how do you define pornography that won't also get eg breast exams for cancer blocked? Now imagine that someone stands to make tens or hundreds of thousands of dollars if they can get something past your very human operators that both is (according to viewers) and is not (according to the censors) pornography.

The problem's even harder with text - sarcasm and satire just don't come off in pure text. Emoji and "/s" helps, but they're not requisite.
I use magit in emacs and I can create any commit I want by slicing out a bunch of characters in a diff.

The git CLI is workable for a lot of things,but the experience of higlighting an arbitrary block of text and saying "commit THIS" has not been matched in any other git UI. We're not talking about hunks or lines here, but literally committing an abitrary range of characters.
I'm curious how this squares up with the failure of drugs targeting beta-amyloid plaques. Despite some of these drugs being very effective at clearing Aβ plaques, they don't seem to ever achieve any significant benefit in clinical trials.

Reading Derek Lowe, you'd get the impression that the beta amyloid hypothesis is a formerly exciting thing of the past with a disastrous track record.

>the relentless failure in this area, when amyloid plaques seemed for so long to be the most likely causative agent for the disease, is really something that makes you question things.

>Add in the additional complete failures for every other attempt at the amyloid mechanism (secretase inhibitors, for example) and you start wondering if amyloid really is a cause of the disease or not

Now Wikipedia is more optimistic:

>The "amyloid hypothesis", that the plaques are responsible for the pathology of Alzheimer's disease, is accepted by the majority of researchers but is not conclusively established.

I'm curious to see what comes out of this study, it's a very encouraging result. But it's hard to resolve this conflict of the mechanism looking great on paper, and completely failing in trials.

Generally a fan of your posts, but this one was very heavy on marketing buzzology ("cloud scale"). I can't tell if there was a genuine use case for designing a proprietary SSD, or if it were some pet project. Is "75% lower latency variability" because the first gen SSD was a CS101 project, or because AWS have developed some material edge over what others (with much wider scope) in the industry have been doing for years? I can't tell.

I can't see a reason to buy or use this product.

I don't understand what the new virtual lines feature does. Can anyone explain?
Most people already have persistent servers - smartphones. Considering how much tracking data and ads are already sent up and down the network by apps, installing a tiny web server to share a simple blog or image gallery shouldn't make a huge difference. And 24/7 uptime is not strictly necessary; considering digital wellbeing, that might be an unintended feature.
I actually hope the WikipediaQL, when it will become a bit more mature, to be helpful in parsing Wikipedia data _into_ Wikidata. As of now, Wikidata lacks a lot of knowledge yet (the article talks about that, too).

Realistically that basically calls for taking over the world as step one as it would be required to enforce demands upon others.

The "stop exploiting poverty" sophistic frankly doesn't map to reality. If the US pulled out of trade in Vietnam they would get worse off instead of better. The issue isn't the result of an action to be stopped which turns the entire notion into dross covered up with guilt tripping.

It is the same "leave the cookies on the table to gather dust while trying to eat far richer imaginary cakes" mental pattern as IP zealots who snub overseas direct sales with things like region locks because they think they could get more selling distribution rights months.
>and told someone else to type that word in, we would both be culpable.

Perhaps as some technicality but in reality who is (much) more culpable? Who would think a computer would be made so poorly that it fails dangerously if the wrong word is typed in?

One could say they didn't believe it would be true because it sounds too implausible.

Same with a car that drives off the road if it sees the wrong thing on a t-shirt.

I don't think it's fine for a company to just make products that are super dangerous if some slight edge case is met. In my opinion they would be liable.

Otherwise terrorism can be legal if you slap an "AI" label on it.
Ask HN: As an outsider, how could I publish a white paper?
Hello HN

TL;DR: I probably created the fastest "find all K simple paths" algorithm for a weighted or unweighted, directed or undirected graph. How would I, as an outsider, publish the results? If I'm right, I'd like to benefit from this discovery to open doors to more interesting work/careers. (I fear, in my 30s, I am at a huge disadvantage for not having any big co. or university to list on my resume)

Background:

I am outside of the tech "scene" and have no tech/academia connections (self taught, no time spent in university). That being said, I've been programming and managing operations (working as the sole dev at small co.) for 10+ years. I recently quit my job to reevaluate my career path and for fun, started working on a city builder video game. The first big problem I had to solve was "how can I efficiently simulate people/cars utilizing ALL the fastest paths available to them?" (in case you aren't aware, Dijkstra's algorithm only returns one shortest path from start to destination).

Solution:

I created an algorithm that has a time complexity of around O((V+E)log V) and a space complexity of around O(n^2).

Now:

I tested the algorithm in my game world and watched my digital citizens utilize all the shortest paths available to them for various destinations around the map. For a heavy load test, I created a 100 x 100 grid (where each square is a node), and my code takes 1.75 times longer than Dijkstra's. Since I can store the search tree I created, I can move tens of thousands of units around the map without any lag (using SFML vertex arrays for efficiently handling the screen draws).

I started researching other existing solutions and to my surprise, my solution is faster. Eppstein (1997) is the fastest solution I came across @ O(E + V log V + kV), where k can grow at some binomial coefficient (thus would be terribly inefficient with hundreds of nodes, let alone thousands, if many fastest paths existed, which is the reality of most cities if you walk).

Other notes (excuse my lack of traditional education here):

This does not prove P = NP (phew! I'm safe.). While the number of shortest paths can grow at some binomial coefficient, the classification of all possible paths does not. To explain by example: Going from node (A) to node (G) could possibly use nodes (B, C, D, E, F) along the way. So A-->G is a classification. When we add a new node (H) to (G), that (A) can only get to via (G), the A-->G classification is not changed. On the other hand, if every node connected to every other node, the amount of classifications would increase at an exponential rate (and devolve into all NP-Complete problems), and the possible amount of k paths (not necessarily shortest) would grow super-binomial coefficient-ly.
I think this is more like long haul wifi for your corporate campus, factory, port, university etc. Maybe even for things like parking meters (san francisco's parking meters are famously being updated/upgraded because they're ending EDGE network used by the modems in the parking meters)

One question I have is, I thought the cloud was supposed to abstract this kind of stuff away? Shouldn’t cloud services be sold in the “solution domain” rather than by picking the backing technology behind your tool?

For example, why not have a file/object/whatever storage service; and a price matrix that lets you select key metrics like latency, throughput, and variability of either?

I don’t particularly care if my ultra fast ultra low latency is derived from SSDs, spinning rust, RAM, l2 cache, or acoustic ripples. But I’m not super in tune with cloud services to begin with.
I predict that people will leave Washington State in droves. Not because of the tax increase, but because the amount of taxes you pay goes into never ending government pit of inefficiency and incompetency. I’m down with paying more taxes but in return I want no homelessness, no chadzone, less crime, better roads, straight forward education (math is racist apparently), spotless streets, safety, eradication of poverty, no power cuts, and better law enforcement.

Better yet, instead of increasing taxes, how about we improve the efficiency of the government? For same budget, we can get more done. We never seem to ask this question.
Having met a bunch of people responsible for ad budgets totalling $1B+/yr, this thinking seems almost the direct opposite of what they're after.

Everyone thinks only about the goods and services they're trying to promote, not the health of the advertising industry as a whole. Each platform wants to get more revenue, at the expense of other platforms if necessary. Each advertiser just wants to place ads on the platform that gives the best ROI.

First step: Do nothing. You've got two working, independent products, and that's okay. You can keep running like this indefinitely so there's no need to rush.

Second step: Figure out what the future combined product/company is going to look like. There's no sense doing any integration work until you know where you're going.

Third step: Form a combined team and come up with a plan to build the new product, reusing and rewriting the existing technology as appropriate. The details here entirely depend on the existing products and the end goal.

Keep in mind this situation can easily become political and toxic -- in fact, I would say that's the default outcome -- and will require strong leadership to navigate well.
It doesn't seem like they draw any correlation to food intake since the mice were genetically modified to just emit the proteins from their livers.

My guess is healthy diet and exercise go a long way. Don't drink and avoid sugar (diabetes) both of which are damaging to the liver.
I imagine most medium to large enterprises using AWS have some discount, especially if you are operating at the kinds of scale that this article deals in.
> Let's not forget that HN's primary function is to attract people with ideas for YC to turn into companies whose equity generates money for YC

I don't know about primary function but it's one of them, let's say. The interesting thing is that this has exactly the opposite consequence to what you say. Doing things to jeopardize the good faith of the community would not only be wrong, it would be catastrophically stupid. Therefore, not only do we not to do it, we place the highest priority on not doing it. That follows straightforwardly from the mixture of your premise with raw self-interest, so I'm not claiming anything hard to accept. Well, I guess I'm claiming we're not catastrophically stupid; maybe some find that hard to accept.
Ah from the time of great widget wars, when Motif and OPEN LOOK were battling for GUI supremacy. I was vehemently team OL (via Sun's OpenWindows flavor) and absolutely loathed how bulky the borders felt on Motif windows.
I suppose it works out to be the same if the cause of death is distributed evenly among all ages, but I suspect that's rarely the case. If something causes a lot of people to die at 90% of average life expectancy you wouldn't want each one to only count as one tenth of a death.

I didn't believe in the Metaverse when William Gibson or Neal Stephenson wrote about it, when people were selling virtual office space in virtual malls, when it was called SIM CITY or SECOND LIFE, and I don't believe in it now.
Sharing office files is such a pain though. Let alone support for different formats, there's always inconsistencies between editors and versions. Issues were so common sometimes I'd create bad files to pretend I'd done my schoolwork, and no one suspected anything. OOXML presumably tried to fix this but it's so huge and difficult to implement.

Not "recently". Disappearing messages have been there for at least 5 or 5 years.

Almost _all_ my Signal chats are on 1 week or 1 day disappearing settings. It helps to remind everyone to grab useful info out of the chat (for example, stick dinner plan times/dates/locations into a calendar) rather than hoping everybody on the chat remembers to delete messages intended to be ephemeral.

The "$person set disappearing messages to 5 minutes" has become shorthand for "juicy tidbit that's not to be repeated" amongst quite a few of my circl3es of friends. Even in face to face discussion, someone will occasionally say something like "bigiain has set disappearing messages to five minutes" as a joke/gag way of saying what used to be expressed as "Don't tell anyone, but..."

(I just looked it up, https://signal.org/blog/disappearing-messages/ from Oct 2016.)

Obesity and income are related. Curly hair can be considered unkempt.

Discrimination (hopefully) is a small percentage of most of our lives, but it is real. Black hands holding a product in a craigslist ad gets fewer hits. If you're a racist and buy a bicycle, get there and the guy is black, you'd probably still buy it, because you're already there

Huge +1 to this btw. If you are in the position of owning a gas stove, make sure to always run the range hood vent whenever using the stove.
I am gonna join this opinion.

It's quite likely that one of the products takes over. Maybe one product had more traction with customers, or maybe one product is losing customers. Maybe the entire sales or development team will leave within a year, leaving one product in shambles. It's quite possible that one organization will be torn apart, who knows the terms of the acquisition.

Notice that in this arrangement

1 2 3
4 5 6
7 8 9

opposite values add up to 10: 1 + 9, 2 + 8, 3 + 7, 4 + 6.

Why these numbers do this is simply because the sequence is laid down in left to right, top-to-bottom order in a symmetric way, and these values pairs end up equidistant elements from the opposite ends of the sequence. If you put your index fingers on 1 and 9, and then count upwards with the left one and down with the right, you can see how this plays out.

And this summing to 10 to do with why the last digit of the sums you are seeing is always 0: 3330.

For instance in 123 + 321 + 456 + 654 + 789 + 987, the last digit is (3 + 1) + (6 + 4) + (9 + 7). We can rearrange these six numbers into (1 + 9) + (4 + 6) + (7 + 3) = 10 + 10 + 30 = 30.

Ok, so now we have a 0, and a carry of 3.

Next, note that since the diagonally opposite elements add to 10, all the three-element traces that pass through the center 5 necessarily add up to 15: (1 + 5 + 9) = (2 + 5 + 8) = (3 + 5 + 7) = (4 + 5 + 6) = 15.

In calculating the second digit of the sum you have 2 5 and 8, which occur twice: (2 + 2 + 5 + 5 + 8 + 8) = 30. Combine that with the carried 3 and you get 33. Put down the 3 and carry the 3.

Then again, the 100's digit is just mirror image of the ones: it adds up to 30, which combines with the carried 3 to make 33.

With 784 + 487 + 159 + 951 + 623 + 326, though you have rearranged the digits to form corner triangles, that is just a red herring. If you look at the ones digits inside this sum, you have 4 7 9 1 3 6. These is just the set made up of the left and right columns of the square, which we know can be put into 3 pairs adding to 10, making 30. Again we get our 0 to put down and 3 to carry.

The middle digits, the tens, are once again 8 5 and 2, doubled up again: another 15 x 2 = 30: put down 3, carry 3.

And so it goes.
Thanks, however I come to this post after reading the full blog.

You are on right path. Its of no use for consumer. Private 5G cant compete against WiFi with current ecosystem. The end devices dont support 5G modem (or 4G). It cant compete against WLL (Wireless in Local Loop) (Means Wireless based broadband service). As you need dedicated internet service to configure p5G (private 5G) and to let it remain active, there is no business case for p5G for broadband service/WLL. There is another service, FWA/Fixed Wireless Access, by different 5G provider where you get a receiver which is connected to home router.
Good question is, what this hype of p5G:

1) Industrial area coverage: Where you need 50 WiFi radio unit, you can provide service with 3-4 p4G/p5G radios.

2) Hazardous areas: where you cant provide the networking at all the corners or areas, one p5G radio blast area (esp with beam technology) can provide the coverage.

3) Security: Mobile phone systems are based on shared secret and proven to be secure in terms of access compare as well as on air to other technology.

4) Packet loss: Less packet loss compare to WiFi (believe me, its big deal in Industrial world)

5) Compatibility: what's a negative for 5G modem (not many devices are available), is positive to some extent. Once investment is made with 5G modem, the device can be on road too. THink like, acting like enterprise node in p5G area and limited services outside (or device consumer).

6) Edge computing: With new standards, the applications can run at the edge. Those can be done currently with WiFi too. But WiFi has limitation of devices counts (too many needed), path reliability and geographic coverage. Whole factory or port or airport can be covered with small p5G footprint with specific applications running at the Edge (I live in this world :) )

p5G will be game changer in enterprises with large complexes with moving assets.

You won't have time for it all. And when it is all over, nobody wishes they had spent more time working. So find the balance - do the work you need to do. But then put it away and do the activities that will leave you on your deathbed (hopefully old) saying, "Yeah, that was a good life."

If you keep that perspective when making all your choices... well, you'll still make mistakes - mistakes are part of youth. But they will be made with good intent and hopefully keep you growing and living in a good direction.
Don't assume that they will ever be a single product - but do assume that they will move closer together.

Work out what that first task is - often the best place to start is the UX rather than the back end (as the UX may be easier to merge onto a single platform/codebase), and then you can have the two products having a similar 'look and feel'.

Then you can start looking at other bits to merge - for instance can you use the same database engine, languages, coding styles?

But the most important bit - don't go rewriting it all Big Bang otherwise you will just get yourself in a rut.

The part that will be the most difficult to change is the business logic - if the two products fundamentally have different processes it is very difficult to merge them together (from a customer perspective). A decision early on is required to know if they will fundamentally be two separate products, or if they will kill one and it will become one product, but you can't have one product with two different ways of doing the same thing for every feature.
This is something I'm having a hard time figuring out, whether burning wood or natural gas for heat is net worse. If people are burning nat. gas for heat instead, that is still resulting in emissions around you, but can anyone confirm wood emissions are worse healthwise? On the other hand, won't burning natural gas greater contribute to CO2, since it's taking long dormant reserves and releasing them, rather than wood which is a short term cycle? That wood will be decomposed/burned sooner or later anyway, just maybe not in a populated area.
