I do this often myself - search another site for the correct item, and then take those results to Amazon to actually purchase.

For me, personally, while "Joe's Truck Parts dot com" might do a better job of finding me the floor mats that fit my truck (or the manufacturer) - Amazon already has my credit card on file, and my address, and (for the most part) ships anything I order to my doorstep within two days. So I know I'm not transferring my credit card data to some random, sketchy company who stores it on some Windows 98 server, and takes 2 weeks to ship me my product, and when they finally do ship it, it could take 7 days to get to me.

In either event, I do like to support local business and small business - but I enjoy the convenience and familiarity that Amazon offers...so even if their search isn't the greatest, I'll still be clicking purchase on their site, for the most part.

BASIC made it easy to learn incrementally, one line at a time. Syntax and block issues in Python require too much up-front training, in my opinion. And, the library issue is not mutually exclusive. BASIC could be given libraries/functions that do dramatic/interesting things: "10 boom(100, 200, 50, 3)"

This makes an explosion at coordinate x=100, y=200 that is 50 pixels wide and lasts 3 seconds, including sound. Put it in a loop that slowly increases the size or decreases the duration. What boy doesn't want to have control over screen explosions? (I may be gender-stereotyping, but you get the idea.)
Another possibility: higher vitamin D levels are associated with health because people who are outside more might be getting more exercise, and it's really the exercise that is doing it.

That seems like a straw man to me - they’re saying the tax should be higher for people in their class generally, not that they individually wish to pay more.
If site search is something that Amazon does that badly (which they do), then why would you think that doing it well is the key to beating them? If it's not necessary to be a sales giant, then why assume it's sufficient?

I haven't used Mastodon, but this is kind of the reddit model, right? Obviously some subreddits are >>> 1k subscribers, but they typically scale the quantity of moderators up accordingly.

Do Mastodon admins share common blocklists or anything? If a bad actor decided to start posting offensive content to random instances, I assume you can ban that {username | IP} from the instance used by you and your users, but would they then be able to just iterate through the other n Mastodon instances? Is there anything in place to prevent them from creating a new account and repeating ad nauseam? (not that there is on Facebook, necessarily)

(I don't know anything about Mastodon, which I'm sure is obvious from some of my questions - if they're incoherent in the context of Mastodon that's totally fine)
4. I think you forgot "build taller"?

" it is ironic how the modern urban population that is so quick to assign blame for climate change (to car owners, carnivores), social injustice (to white men, preferably older), or simply a lack of mobile network coverage fails to understand their own contribution to the problems of a modern city."

What are you talking about? Cars ARE half the problems of a modern city. Car owners are the other half. Rip out the damn parking and put in flats. Ban cars and put in bike lanes. They're far, far more efficient, and have the added benefit of not mowing down pedestrians and boiling children.

Sapphire is an incredibly trivial compound, aluminum oxide.

The problem is, its melting point is huge. To make artificial sapphire you have to melt the stuff at very high temperature and let it drop and collect onto a ceramic base or something. And then you cut, grind and polish it into shape, which is not easy either because it's an extremely hard material.

The challenges to making a large flat plate of AlOx would be huge.
Well his buddy Warren Buffet also says he should pay more taxes. I find his stance refreshing - he's going to pay only what's required while advocating changing the rules so that everyone pays more. Lots of people say "well he's free to pay more if he want's to but he's not". Some call it hypocrisy. Some call it humility.

I am sure if someone really, REALLY wanted to give money to the government it would be possible with some effort. But it is actually fairly difficult to just give money (at least, in quite a few western countries) to the state that it does not ask for - everything has to fit within a system and match a budget, tax reason, invoice, etc., and you can't just have "EXTRA - From Bill Gates" somewhere in there for 10 billion dollars.
I have an Asus (Model UL50V) from 2009 with an Intel Centrino- 4 GB RAM. It's my everyday machine. It is getting slow at many things (but a recent hack to Thunderbird settings helped a little). I dual boot Linux Mint 17.2 (Ubuntu 14.04 IIRC), although I haven't actually booted windows in years. I have a Toshiba Satellite for travel, windows 10, and in virtualbox I have a Mint system that basically recreates my work environment (which is usually Fluxbox).

The one good thing about about using the old system is that using Virtualbox isn't annoyingly slow.

I am looking forward to upgrading my work box to a linux-native desktop (System 76 or such) and joining the modern age! I was hoping to outwait Spectrum/<forgot other name> but now that is looking hopeless?

Chromebooks suck. Just buy a cheap Windows laptop (and most recent models are going for the Chromebook-like "ultrabook" form factor anyway, even at the low end) and put lightweight Linux on it. You don't really get better specs for the price if you go the Chromebook route, and the whole way they're setup makes them pointless toys.

(...No, I'm not going to look for the correct custom firmware for whatever my model of Chromebook happens to be, or put up with a machine that will wipe its storage unless I hit the right key combo as it boots! Again, that's hardly a marker of a professionally-built device!)

Yeah, apartments is one part of it all. I'm trying to find a place in a kindergarten and it's hell. In Berlin kindergartens are free for some time and there are no free places. My wife today tried to find a place in a private kindergarten, no luck even in one for 800 EUR/month.

If we knew German language and customs better maybe it would be easier. But then I would probably just think about creating our own.

We're getting desperate. If anyone knows about a place in a kita in Berlin for a 2 year old, please let me know! Private or whatever, or some kind of coop.

The Virtue of Scientific Thinking
> Do LED lamps not produce light via blackbody radiation?

I'm pretty sure the answer to that is that they do not.
Choice of E5 for a deleted entry:

#1 E5 is a "sync byte" it cannot be rotated and mis-interpreted: E5 E5 E5 ... can be used to synchronize a bitstream. Note that floppy discs are read bit-wise.

#2 Empty 8" floppy discs came pre-formatted with E5 written everywhere.

#3 05 is a "control-e" in "extended 8 bit ASCII (IBM encoding)". E5 was a usable character.

With CP/M, the disc bitmap was produced when the disc was "loaded". All directory entries were scanned, and the allocation bitmap was produced. A freshly formatted disc would have E5 fill, and thus would have no files. MS-DOS had a separate allocation table, which was also the file linkage table. So, the strategy of a fresh E5 filled disc being taken as empty no longer works. But, the key of a deleted entry having E5 as the initial character was still used.

Hope this helps.
Angular Routing – Best Practices for Enterprise Applications
I know, I've had these arguments. But it's asinine because it is quite literally impossible for any human to exist without animals dying as a result of it. There are a small percentage of vegans that are convinced that their existence results in zero animal deaths. These people are delusional. Luckily there aren't many of them.

The reasonable vegans admit that it's a matter of causing as little animal death or suffering as possible. And then some percentage of what I've deemed "reasonable vegans" will also agree that hunting is about as good as any other options.

It's less about it being for you, and more about that it would be hard to sell ad space when it sits next to content of that type. Your friend might not post those materials, but what about Pages and Groups, which is where I'd say most FB users spend their time these days.
I can understand your feelings, and he is a bit contradictory in the sense that he has stated publicly that governments are not the best enablers for certain projects.

American Health Care system that preys on the old and sick.
My dream for an online store is the following:

A magic list that I can add any item to, select a delivery date, and have the backend automatically fulfill each item, at the cheapest price, on time. I want to completely abstract away the concept of a store. I want a to-do list that automatically delivers stuff to me. Additionally, I want a standardized return policy no matter who fulfills it.

I want to be able to say:

- (3) Organic Roma tomatoes

- (6) Sonicare replacement brush heads

- (1) Patagonia Down Sweater, Black, Medium

- (1) Bookshelf assembly service, in-home, 3/16/19

and magically have it fulfilled. One could have a slider to make the tradeoff between speed of fulfillment and cost.

Amazon already sort of does this, but not at the best prices. One would hope that in the magic to-do list model, local retailers would be able to outbid non-local retailers, as their shipping costs would be inherently lower.

I don't know the details but I recall that using linux as a bootloader was a potential threat the ChromeOS people wanted to block with some patches to the Linux kernel that tied it somehow to secure boot that the kernel maintainers (Linus himself commented on the issue as it was controversial) rejected at the form the patches had at the time.

Author here. I'd appreciate your feedback on this article that builds off a series of articles teaching basic Scala. I'm particularly trying to create materials to teach basic Scala to non-engineers (chiefly data scientists) because I've found Scala to be a powerful language for my data science and analysis work. The goal of the educational series is to build up to using Scala in Spark within a managed Hadoop cluster (e.g., Databricks).

In this post, I'm trying to use exercises that I think will be more interesting and engaging than just showing off the language. What do you think? Is analyzing Redditors interesting to you? Do you have any thoughts for other datasets that would be even more interesting for people to work with while learning Scala?

In general, I'd appreciate any critical feedback because I'm looking to get better at developing such educational resources.

Thanks for your time!
>DDoS amplification vector.

How would a TLS-using protocol be used as a DDoS amplification vector?

>If you give an address that always sends back ICMP unreachable messages, the client fails immediately and continues to load the rest of the page, but DNSSEC proscribes that.

You can return resolver errors or no data, there is plenty of options for DNS blackholing.

>There are also circumstances where you want to return a specific address, e.g. so that attempts to send traffic to that address can be monitored, and redirecting the address doesn't work because it could be a shared host using SNI and you don't want to affect every name pointing to that address.

You'll need a PKI for that anyway so you can deploy DNSSEC root keys.
Yes. Otherwise there would be no reason to live as long as we do.
A Low-Latency, Low-Area Hardware ObliviousRAM Controller [pdf]
I'm not sure why I'm replying to click-bait PR, but here it is anyway:

Maybe I'm alone here, but I have an extreme distaste for personalized search results. I know what I want to see; it's pretty rare search knows what I want to see when it's trying.

Take the "chips" example from the interview--maybe I'm tired of eating the same fucking chips every day. Maybe I just want to know what the most popular options out there are without having to scroll a lot. Not to mention that I have a preference for Pringles, I'm going to type the brand name into the search when I want to find it. (If I'm a dog lover, I don't expect Google to rank dog results first when I type in "animals." I expect information about animals in general.)
The ability to semi-tinker with the economy may lead to leaders with a false sense of full control. They may find a way to shuffle things around to hide problems most of the time, but eventually they'll make a mistake, all humans do, and create a problem bigger than further meddling can fix or delay. Historically, autocrats try to fix big economic problems in ham-handed ways that make the problem worse.

This is not to say that open systems don't also have problems, but it's harder to sweep things under the rug when your political competitors can and do broadcast all your mistakes to the public. Checks and balances.
I don't completely agree with your assumption that living in Tokyo means you need to live in a shoebox (and especially not in Osaka which is about 2/3rds the price of Tokyo), but actually I think there's a case for cheap, somewhat-cramped housing with good transit access to the city, for those who want it.

In Japan, a middle class family can own a somewhat cramped (say 900 sqft?) 3bedroom house/apartment walking distance to a world class rail system and generally walking distance to schools and some stores too.

In America's top cities, a middle class family can't afford to own a 3 bedroom apartment with rail access generally, so they move outside the city to the suburbs where they often have to drive to work - which means they need to buy a car, buy gas, etc

But if you don't want the lawn and the picket fence, why is this the only option available? We've taken a one-size-fits-all approach with covering the vast majority of the country with big suburban houses, and the free market is proving people want options, evidenced by wildly inflating prices of urban properties.
