I've recently found that the price of Lego - at least on the used/second-hand market - has fallen, depending on what you are looking for.

Complete sets are still hella-expensive - especially vintage ones. Certain custom models can also be very expensive. Lego Mindstorms of the past two generations (NXT and EV3) are also still up there in price.

But bulk Mindstorms, Technic and Expert Builder are all still fairly cheap (just stay away from pneumatics - that stuff is still pricey for some reason).

I have found the Mindstorms RCX 1.0, 1.5, and 2.0 (aka - yellow programmable brick) are all fairly cheap. The touch and light sensors aren't too expensive, and the going price for the PB is around $30.00 USD. Rotation sensors can be up there sometimes, and the temperature sensor is hard to find and expensive. Motors are cheap though (the 9 volt block ones) - most can be had for around $15.00 each.

Bulk parts are similarly low cost. Even the NXT and EV3 motors and sensors are fairly inexpensive (not as cheap as the older RCX, but not crazy). Since they use standard interfaces and connections, they can be easily controlled using a Raspberry Pi or Arduino. The RCX takes a bit more work (you have to use an h-bridge for each motor, and sensors require an ADC; easy on the Arduino, but you need something external for the Pi).

The various Mindstorms "Vision Command" and similar cameras are also fairly cheap; they aren't anything special - very low-res (352x488 IIRC) web cameras in a Lego enclosure. But you can get them to work with Linux (you have to preload the
V4L1 library before executing a program like cheese or whatnot) - this used to not be the case (no driver existed about 8 or so years ago).

But yeah - if you're ok with hitting the second-hand market via Ebay or garage sales, you'll find it's now fairly cheap (again, staying away from things like the latest Mindstorms).

Oh! I also found that the Lego Dacta Control Lab (9751) interface can also be found cheaply - you can get 'em for $40-50 USD; they work with all the old 9V sensors and motors for the RCX. I've read that you can use a USB to DB9 serial port converter with them, and there is a ton of 3rd party libraries out there for control (I found ones in C, C#, Python, and Java).

In that, I agree with you.
Yes, definitely. I wrote (or contributed significantly to) dozens of docs for Jeff Bezos and his senior team. It was important to understand whether you were writing a 2-pager or a 6-pager (depended on a number of factors, mostly relating to complexity of the issues involved, the size of risks, and the variances in expected outcomes.)

Two examples:

(1) An acquisition memo justifying a functional/technical area (and specific target company) that we wanted to be able to move into due diligence with.

(2) A recommendation related to whether "Alexa" (the service) and "Echo" (the device) should have the same or different names.

In case you're wondering, the former was a 2-page and the latter, a 6-pager. In each case, the recommendation that we presented was accepted, the second after much more vigorous debate than the first. Jeff was initially strongly opposed to having two different names.

No one would read a 40-page document, but there were a few times when we ended up with 6-pagers that contained 20+ pages of detailed appendices.

I also believe that the culture of the document is a key success factor for Amazon (but that it can't just be cargo-culted into other organizations without a lot of buy-in).
And then once you put it into place you realize that your system is not sustainable, just like every other country's healthcare system due to demographics. Now you have a big problem on your hands and the only real solution is to cut back on spending.

>I run an old collaborative writing (roleplaying) forum populated mostly by teens that's paid for by a banner ad.

I know this is going to sound like heresy nowadays, but you could always just run your forum and pay for it out of pocket. Believe it or not, once upon a time, a huge portion of the web was made up of labors of love like that!
> You don't need to finish books. Stopping mid-way is fine (still have problems with this!)

I think this is important with non-fiction. A lot of books can be wrapped up nicely in 80 pages, but the publisher wants 300. So they get a lot of unneeded padding at the end.
Clever. Is this possible with 64-bit numbers somehow?

The DoD might also be interested in a bridge in Brooklyn that's currently up for sale. It's a real steal, and could be used to replace all their other bridges, too. In fact, it'll revolutionize bridging.
They don't really have a choice. Your publication record is the most important factor you're judged by, and that determines your chances to become a professor and to continue to earn grant money to do some science.

If you have the option to publish in Nature or Science, you have to take it. Or you will stunt or kill your career.
> For example the whole of Japan had 28 million visitors in 2017[0]. I couldn't find more recent stats but Austin TX had 20 million visitors in 2011-2012.[1][2]

These numbers are apples and oranges. For Japan, the number is for foreign tourists, while for Austin it is for all tourists. Tokyo and other Japanese cities also have domestic tourists, which aren't being counted in your 28 million number.
> "Ad blocker" is #1 thing that should be installed first on every single browser, everywhere, to block third party ads.

Agreed. But I don't block ads just because ads are annoying. I don't even block ads because I don't like being tracked. My reason for blocking ads can be summed up in a single word.

Malvertising.

As soon as ad networks began trying to spread malware through ads was when ads moved from being a nuisance to a serious security concern.
There are a lot of people that are preferring to do Airbnb instead of traditional rentals. Your comment reminded me of another article (may have been previously posted on HN).

I agree with your general point, but there's no paid version of Facebook that shows no ads and doesn't sell your info. (And, if there was, I'm sure it would bomb.)
And the product's non-obfuscated cost.
As a student I paid £5 p/m, and I've definitely had a coffee that cost me £5.

As a not student, I pay £10 p/m. As I've had coffees that cost me £5 in the past, that is two coffees.

It's only ridiculous if you view NYC through some rose tinted glasses, most the rest of the country are staying away

Responding to your points.

1.) Most online rags and news reports describe it as "crumbling" so these aren't my words. I have no interest in being melodramatic, I'm merely relaying the portrait painted by most people reporting on the subway.

2. You call BS. I call that article proving my point. You are having a market correction due to the mass exodus.

3. Name other major tech companies besides Amazon which hosed over the city and held them hostage for sweet heart deal?

I don't know one person that has said "oh I know, I'll move to NYC for a tech job" San Fransisco maybe. Austin? Definitely.

I just don't know how you can paint a billion dollar loss in tax revenue (2.3 billion state wide), and falling housing prices due to decrease in demand as a "boom"

The mere fact that NYC bent over backwards so far to attract Amazon is actually telling to me.
For this equation:

n/d = n * (2^N/d) / (2^N)

What is "N"? They didn't seem to explain that, although they say "Yet for N large enough", and "drop the least significant N bits". Is it just a very large integer? Or maybe the maximum integer for a certain number of bytes?

EDIT: I'm reading this Wikipedia article: https://en.wikipedia.org/wiki/Division_algorithm#Division_by...

For a 32-bit unsigned integer, you would use N = 33 when dividing by 3? And N = 35 when dividing by 10? I'm struggling to see how this works.

EDIT 2: I think this post helped me understand it: https://forums.parallax.com/discussion/114807/fast-faster-fa...

"The·basic idea is to approximate the ratio (1/constant) by another rational number (numerator/denominator) with a power of two as the denominator."

Their example:

(n/10) = (n*205) >> 11

Maps to the original example:

n/10 = n * (2^11 / 10) / (2^11)

2^11 / 10 = 2048 / 10 = 204.8, which rounds to 205.

So N would be 11 in this example, but I guess it could be any value.
I worked pretty hard (IMO) to get out of Raleigh so that’s funny to hear.
The red bull one was settled out of court, wasn't it? Also, I almost feel like the red bull lawsuit is the same deal as the McDonald's coffee one - legitimate complaints being marginalized and derided as obvious issues (humans can't have wings, coffee hot).

The red bull suit argued that with the 'gives you wings' slogan and other advertising, they suggested it's better than, say, a cup of coffee... but there's less caffeine in red bull than coffee, and not a whole lot else in terms of stimulants. Whether that's enough to be really false advertising, I'm not sure, but characterizing the lawsuit as being about just the slogan and actual wings isn't accurate.
It does indeed. The question you are asking leads me to believe you haven't read it. As a favor to the thread I will make this plain: drop everything else you're reading long-form and buy a copy of _Bad Blood_; it is fantastic. I didn't give a shit about Theranos. Until I got a couple pages into Carreyrou's book, that is.

That's not the question, the question is "was it morally wrong to drop the nukes?"

My position, based on my classes on the rule of law in warfare from a US service academy, is that civilians are an illegal target for the military and using a nuke on several hundred thousand people to take out a handful of industry is definitely outside of acts of legal warfare. It's different to target a manufacturing facility directly, even with civilians inside.

So, this isn't an argument, my position is the correct one. Even a US service academy teaches its officer candidates that the nukes were objectively wrong. The lives of civilians are more sacred than the lives of soldiers during wartime, legally.
For non fiction I only read what was directly recommended by somebody whose taste I already know. It takes discovery out of the equation and I definitely miss good books, but since I do not read that many non-fiction books this method is highly efficient.
Do you have a source for that? "Most" seems hard to believe.

I would also be hesitant to take the top 500 as representative of the top, say, 5 million.
What is consciousness without the concept of self, though? "I think, therefore I am" is the basis of how we view human existence, and there is no reason to not think that the concept of self is just another illusion created by our pattern recognizing brain.

> On another level, it bothers me that there are such large institutions that can arbitrarily "bless" random people like a deity or something.

It's not all that different than in the past some regular person assisting the royalty, and being rewarded for it with some money or small title or allowance, such as being able to utilize a natural resource that's controlled by the crown. It's just a consequence of a massive power disparity, and those are natural (I mean even without market power and m oney, we're talking about a single person and an organization of tens or hundreds of thousands or people, which is its own power difference).

> I also can't help but look at this cynically as a largely self-interested PR grab by Apple that is not a real sacrifice on their part.

It probably is, but that doesn't mean its all it is. It's not always a zero sum game, and if you can help yourself and help someone else at the same time, should we denigrate that just because it's also self serving? Tempering how much good will we attribute for this action is all well and good, but let's not go too far and negate all of it or come away thinking worse of Apple just because they gain something from this as well.
Did you read the post? He specifically calls out biographies as the exception to the 'no journalists' rule and describes why journalists are well suited to write bios.

In other words there's no reason to believe the author would miss any of the books you mentioned by his "journalist disdain".
Heh, I tried getting started with New Relic. I didn’t want to give up my name (over chat mind you, not a signup form) and phone number so I never got that account.

No it's asymmetric. That's the whole point of this discussion. If it was symmetric it could go in either way and there wouldn't be an issue.
How many people have gotten malware from Spotify ads?
First of all thank you for your comments. I thought, Show HN "is for something you've made that other people can play with" and of course we do not have all "attributes" at the moment. But you can play with it without money or any obligation.

Also could you explain what do you mean "partial open source client"? All client code is on GitHub. If you follow link https://savefile.me/client/savefileme/api and open html code, you can see same GitHub url: https://github.com/savefileme/savefileme This is remote import path following golang specification: https://golang.org/cmd/go/#hdr-Remote_import_paths meta name="go-import"

It is used to not bind to a particular hosting like GitHub or others. But you always download full source code and can inspect it before compiling.

Paying is giving money in exchange for something.

Seeing ads isn't like paying, it's being subjected to a small amount of mental pain - that of not being able to do what you want because there's a commercial distracting you or blocking you from your goal.

It's actually a type of cruelty when you think about it.

When i was looking in a mirror i didn't like myself, i wasn't beautiful for me. Though my family tried to assure me that i'm beautiful the way i was but i hated myself. So i though i need to change myself!
I looked thousand pictures on google of beautiful girls, and i took a picture of a girl who's body was just perfect for me. Then i started to go to the gym.
At first it was difficult, but day by day i liked it. Also i noticed that my headaches are gone since i'm going to the gym. When i wanted to give up i always had a picture of a perfect girl from internet. And it encouraged me. So it's already a year that i'm going to the gym, i like myself, i feel more confident and i enjoy my every day!
So make a challenge and do it
How do you get the business to agree to your design?

I would love to do something like this but when I used to try I always ran into the same problem.

The business owner would rather me follow the poor design choices of their competitors (hard to read text, bloated, random pop ups, etc). I always did it for them but it really killed me inside.

Some of these new devices remind me of the old "memistor" technology used by the ADALINE/MADALINE machines in the 1960s:

https://en.wikipedia.org/wiki/Memistor

These are not to be confused with "memristors"; the latter being a two-terminal device, while the memistor is a three-terminal device.

If you look at the original papers describing the ADALINE/MADALINE machines, there's a good description on how these devices were originally made - there's nothing about them that couldn't be duplicated today in one's garage or workshop.

So - if you have a hankering to build your own hardware neural "logic" element...

MultiViews doesn't let HTML files have PATH_INFO by default. Only files that Apache considers "scripts" get PATH_INFO (e.g., .php). Therefore /index.html/a.srv would normally return 404 Not Found, even with MultiViews on.

They could have done further configuration to let HTML files take PATH_INFO, but this Rube Goldberg machine of multiple mistakes bears no more connection to MultiViews than mod_rewrite. In fact, I see no mention in the article of MultiViews or its module, mod_negotiation. So how do we know they were using MultiViews and not mod_rewrite, which people use much more often for this amount of indirection?

Either way, this exploit is impossible in the original suggestion, to just use MultiViews with PHP files to remove the ".php"

If by "consciousness" you mean subjectivity, then I disagree. We cannot doubt that we have something that we conclude is subjectivity. The real question/the hard problem is determining whether such a conclusion is true.
I think the journalist rule is good for books that go deep into a topic, like many of the ones you've cited here. On the other hand, I would expand your caveat around biographies to say that journalists are generally very good when it comes to writing about events.

Barbarians at the Gate is a good example of this - it required authors who were able to dig deep into _what_ happened. There's obviously some info on why things happened there as well, but the primary purpose of the book is to inform the reader of what occurred, which is a good use of the journalistic skill set.

Yet FM radio is still free and no one can tell if you turn the radio down during ads
Okay, but your agreement with Spotify on the free tier is "we provide music, you agree to be subject to our ads." If you block the ads, they can then yank the music.

Personally, I haven't jumped on the streaming music thing (iTunes Match is about as close as it gets for me with buying CDs or MP3s to add to it in time), but I don't think what they're doing is a bad thing.

Now, if you have some means to force the various ad networks to prevent hijacking a device and then telling me congratulations for being an Amazon customer and some random item blinks on my screen, I'm all ears. But ads in and of themselves, I don't have a problem with.
Just follow Bill Gates' blog. Lol.

I mean, they're pushing things to your device at your request, because you logged on to use their free service. If you don't want them to push ads to your device, they were kind enough to offer you a paid option where they won't do that.
Yes, you can run whatever software you want on your device. Who is telling you you can't?

In turn, Spotify can prevent whomever they want from streaming their content for free.
Which ones do you develop?

The whole thing is a browser. But Microsoft isn't developing a browser. The rendering engine, javascript engine, network handling, almost all the important input handling, all the things that make it a web browser, they're coming from someone else. And that source has a default shell too.

Remember that the baseline is questioning whether IE counts as a legitimate browser. If you're even slightly unsure about IE, then "shell around chromium" has to be far far on the no side of the line.

This experiment was performed in 2017. The basic criticisms of it are:

- participants selected only from long term unemployed
- Finland was still in a period of austerity following recession (low hiring rate)
- tiny sample population
- limited period
- stingy, the amount provided doesn't really provide a basic income
I don’t doubt that it’s bad in the worst possible scenario: where spam accounts are highly visible to real users and cause them to disengage.

But in practice what we’ve seen on Twitter are accounts that are largely silo’d off from users, who act to “signal boost” certain tweets and hashtags. Most users never even see these accounts, and will never interact with them directly: but they will see content on their timelines boosted from spammers.
The magic is that the writing typically doesn't take that long. It's the digging in, researching, learning, hypothesis building, validation, etc., that may take quite a while. But that's why the documents are so powerful; once you've gone through all that (which is easier to skip, fake, or shortchange in a PowerPoint), the level of preparation and discussion is so much higher. And you likely know the answers to almost all the questions that will come up in the exec review meeting, which reduces the need for and endless series of meetings on the same topic.

So, for me, writing a 2-pager usually took 1-2 hours. After 1 week - 2 months of work getting to the point that I was ready to write. ;)
