When I lived in Brooklyn, the local grocery store had a "wall of shame" with pictures/names of shoplifters. I don't think this is any different.
We're more aware of simple processes that don't work well than of complex ones that work flawlessly. - Marvin Minsky, MIT AI lab co-founder ... via http://github.com/globalcitizen/taoup
Sure, split an amount in 3 payments - take one dollar, put 0.333333 dollars once, 0.3333333 dollars the second time, and the remainder (1 - 0.33333333 - 0.33333333) as the outstanding balance doesn't match what you should have; you should have had 0.34 but you have 0.33 if you round only at the end.

Do the same with a proper decimal datatype, and the same operations give the correct result - pay out 1/3=0.33; pay out 1/3=0.33; the last payment is 1-0.33-0.33 = 0.34 exactly.

The same goes with all kinds of other issues e.g. totalling up tax or discount amounts (calculated as a percentage) where you'll get mismatches if rounding happens at the wrong time, etc.

E.g. ten separate receipts each selling a 0.10 item with a 9% tax or discount will result in each receipt having 0.01 tax or discount; so the proper total in this case is 1.00 sales with 0.10 tax or discount; different than the case if you sell ten such items in a single transaction. If you do all the calculations in floats, you get this wrong.
You just said the answer to the other problem: require a permit or business license to be an AirBnB host. Alternatively, "the market" offers annoyed neighbors another option: move.
No. Working around this takes some effort but is straightforward and uses well-known, existing techniques. There's a lab I know of that considered trying to modify the protein so it could evade the immune system, but they decided against it since they figured the group that published this paper would have too much of a head start and there's no way they'd be able to compete. I'd give it a year or so, and that's assuming none of the other Cas9 or Cas12a variants are already usable.
I am appalled at how bad Facebook did here but buried at the very end of the article Vice does indicate that they needed to provide a valid traceable drivers license and last four of a (maybe?) matching SSN. This means that had they intended to actually publish the ads they would have put some real person on the hook (assuming the submitted data is actually checked against something). Still too easy but for the first 90% of the article I thought there was absolutely zero verification
They have a feature where it spins up it's own access point so that phones and the such can connect and print directly, so your wifi credentials wouldn't be required.

This is actually a really good point. It ought to strike us as anomalous as hearing someone say "the notes are stored in HTM". Thanks.
My question is at what point does Facebook realize that publically displaying people's likes and tagged ins and such is a terrible idea and just stop doing it? And providing real privacy options?
One of the proposals is to replace mole (or define Avogadro constant) and/or kilogram with pure Silicon-28 sphere.

So Germans are making sphere (and are leading the project), but Russians are supplying pure Si-28 poly-crystals. Russians deploy centrifuges for nuclear enrichment, but use them to get highly enriched Si-28. Then Germans melt Si-28 and start growing single giant Si-28 crystal. Then it is made into sphere. Then Italians check it for impurity using gammas, neutrons etc. Pretty fascinating

> You see that as a dystopia. I see that as a better political and social environment.

The question then is...should YOU be the one to decide what is "better"? Who should be given that kind of power?

In an ideal world, a benevolent philosopher king would have that power. In the real world, maybe it's best no one has it.

Maybe it's better to cast the ring into the fire.

When I say it’s in undocumented I mean that the fact that you can use UIkit at all is undocumented. You can use it but you are never told you can. Also there is little documentation that explains things like XCPlayground and PlaygroundsSupport. You kind of have to adapt them from the Xcode Playgrounds for the Mac but the fact that you can do this is never mentioned. Also the limitations on Swift Playgrounds are never mentioned anywhere (e.g. autolayout constraints don’t really work for the Playgrounds previews.

Also, my complaint was that you cannot turn of the debug stuff. You actually can if you turn off things like logging in a template file on the Mac and then move that to the ipad. At that point you might as well just use the Mac though. See here for what I’m talking about. http://saltpigmedia.com/blog/Modules-in-Swift-Playgrounds

Also, as far as I am aware, you cannot add to the sources folder on the iPad itself. That requires a Mac.

My comments were in regard to using Swift Playgrounds as a pseudo-Xcode. It does indeed compile swift code and UIKit, so a lot of that groundwork is there. And I would love to use the iPad to do real coding, and Swift Playgrounds is real tempting, but it just doesn’t work and I find that disappointing.
> VICE News did not buy any Facebook ads as part of the test; rather, we received approval to include "Paid for by" disclosures for potential ads.

Playing devil’s advocate here, but maybe Facebook doesn’t waste time on people who don’t actually buy ads? Would be a much more compelling argument if the were actually able to purchase and run ads, and would be curious to see if the actual act of payment triggered a real review from Facebook.

This kind of feels like me as a software developer saying my code works in production! Disclaimer: I never actually deployed it, I only got approval to deploy it.
> The best solution, and currently in effect as law in many European countries, would be to stop political ads altogether on Facebook and the Web.

I disagree. Not only is that against the first amendment and it is discriminatory. Why should political ads be allowed on other platforms, but not on social media or the web? And why should non-political ads allowed on social media or the web?

Maybe tightening up ad selection, but banning ads or speech isn't the answer.
From the article:

"But quartz oscillators have some problems. They don’t keep time as well at high (and low) temperatures, and they’re a relatively large component—1×3 mm or so. In their quest for smaller and smaller hardware, Apple has recently started using MEMS timing oscillators from a specialized company called SiTime to replace quartz components.

Specifically, they’re using the SiT512, 'the world’s smallest, lowest power 32 kHz oscillator.' "

So it was size, not cost that led Apple to be using a susceptible component.
There was a similar technique used in the tv show Mr. Robot, season 3 episode 9, to hide some secret information (trying not to spoil anything). Ryan Kazanciyan, the Technical Consultant, wrote a blog piece on this technique.

that already is the world we live in: i think every law that constitutes the right to free speech comes with limitations, so regardless there are certain rules you're expected to abide to.

i'm not saying i disagree with anyone or that we should censor everything on the internet, i'm just saying that the internet is no longer that obscure thing where everything is rainbows and unicorns and has become of big corporate and political interest.

so we _should_ excpect it to be like the newspaper, the television, the pamflets in your mailbox, etc. (re: "I cannot tell you how sad that is to write, because when I first saw the internet way back when, I hoped that it would help eliminate the attitudes that had fueled those horrible letters to me. I naïvely thought a lone man sending a reporter a missive of malevolence could not find such refuge on the wide-open internet, where his hate would be seen for what it was and denounced and exorcised"): lies and ways to steer you have become part of the game and it's up to you to see through that.

at this point "do something about it", i think, has boiled down to "delete the internet".
Learn programming, not a programming language
I have had a similar dream before, but with a couple of key differences:

Given that most houses in most Western capital cities now cost millions and given that you can buy LCD panels for approximately the same price as bricks (for the same wall area) I do wonder why millionaires still stick with bricks. You could build a steel framed building and make all the walls, floors and ceilings from LCD panels saving yourself from having to have lights, pictures and regular TVs. With a few solar panels on the roof the electricity bill should be affordable too.

My imagination for this extended to having live scenes from the seaside to have an immersive view of sunnier climes. Your imagination went to goatse though, maybe your fears and browsing habits informed your dreams differently to mine.

Ask HN: Optimal legal entity for an OSS project on the benefits/hassle matrix?
Anyone have an opinion on which (if any) legal entity provides the best ratio of benefit : hassle for a smallish Open Source project that wants to accept donations, likely in multiple currencies (including crypto ones)?

501c3 seems like a big pain in the ass as far as paperwork, directors, etc.

An LLC actually looks like a reasonable option, but perhaps I'm missing something there.

Just not form one at all and have someone be the donations guy?

An interesting point. Namespaced data would include anything related to a repo, github pages domain or organization, ie. almost everything. This would therefore all be readily shardable. Non-namespaced are basically just user credentials and settings. However, looking forward in a post-GDPR/China data law world, "network political bloc" based sharding of user data may also be either a regulatory requirement or a worthwhile forward-looking protective measure. (We just had this conversation yesterday at Infinite Food.) One organization I believe global user data sharding goes on at already is Google.

Retool (YC W17) is hiring engineers in SF – fast way of building internal tools
Hi! We're Retool (https://tryretool.com) - a fast way to build internal tools. We recently launched on HN (https://news.ycombinator.com/item?id=17725966).

We're profitable, growing quickly, and have raised money from great technical founders, including Paul Graham, Daniel Gross, John + Patrick Collison, Nat Friedman, Greg Brockman, etc.

The market for custom enterprise apps is huge. And we think that we have a promising shot at capturing much of it: we have a product that works, that customers love (go talk to any customer), and whose usage is growing rapidly.

We've significantly de-risked the business (good signals of early pmf, completed 10+ unaffiliated sales via cold email, are profitable, etc.). But there's plenty of uncertainty left as well. For example: how do we convert early pmf into actual pmf? How do we scale sales? Should we be doing sales or marketing? Should we be selling to technical or non-technical people?

We're now looking for our first engineer. If you enjoy, and are good at the following:

- building things,

- deciding what to work on, independently,

- and getting things done + managing yourself

We think you might be a good fit at Retool!

If you're interested, please email jobs@tryretool.com. Please include whatever you think could help us understand you, your background, and your accomplishments. For example, a GitHub link to a project you're proud of, plus a short explanation, would be very helpful.

Thanks!
Depends on the reporting - if it's legally mandated reporting or tax reporting, then it's going to get audited and any rounding mismatches are definitely not okay.
"it appears there is no way to boot OSes other than Mac OS and Windows without disabling secure boot entirely."

I am personally okay with that, so long as it can be turned off.
Is this an actual problem? In all my experience I've seen cables fall apart (mainly USB Micro or HDMI) but beyond lint, never had any issues relating to the actual ports.

The lightning contacts are flush with the port, so very unlikely to get damaged. On the other hand the USB-C has that fragile looking wafer on the device-side.
That's a great question I was surprised to see unaddressed. It's unclear what workloads they normally have in East coast vs West coast, or if they have enough capacity to run everything in the West coast.

The source code is paramount, no argument there. But this wasn't about that. I find the metadata less important, but as you say, I don't make the decisions. The factor you aren't considering is opportunity cost given productivity loss. In your hyperbolic example where you claim you'd rather they were read-only for a week than lose 30 minutes of data? I'd rather get things done during that week personally, and if the price I have to pay is resubmitting a comment or re-approving a PR, I guess I'd pay it.

Also, MSSQL has had quick delta snapshot/restores forever (assuming you have them turned on and going every hour or so), mysql really does not have a similar feature?

It's not really about quantity. Reddit had subs for the content the article mentioned. I guess one way to look at it is "it's no big deal because only a tiny fraction of Reddit subs were devoted to neonazis, photos of corpses, stolen sex tapes, and child pornography." That's not how I view it.
As soon as a git repo involves jupyter notebooks I move on. They're ugly, they don't let me learn how the code works properly and in general looks awful. Why not just give me some code to run??

To each their own, but the people who love the area love it because of its weather (meh), family ties to the area, and highly affordable cost of living tied to owning your house for decades, or having rent control for decades. If you're a newcomer, you don't get the last one, which is a huge determinant. It's all you can think about for the area's youth, and the area's old-timers forget about it very easily.

SF is like Sunnyvale in that it's way overpriced, highly-paying, and close to (but doesn't have) scenery. (Yes, I get that there's all kinds of scenery in SF, but I'm referring to Market St. downtown where all there is to look at is buildings, people, pigeons, buses, needles, broken beer bottles, feces, and maybe the bay). SF is older, denser, more decrepit, and smells a lot more like human urine. Having a car in SF is more trouble than it's worth, whereas in Sunnyvale it's a bit less clear-cut.

If you don't have ties to the area, and you don't have to be earning well into the six figures (or have to be there to be earning well into the six figures), I'd skip both Seattle and SFBay. They're rat races, the both of them.

> Taking physical education more seriously as being important for general development, and not something just for the people who want to continue in sports is probably beneficial for everyone in the long term anyway.

Physical education is awful and it is not capable of not being awful. Even if it was not almost uniformly focused on team sports which some people hate to the point of faking illness and others love to the point of obsession, leading to massive capability gaps, it would still be irrelevant. Two or three hours a week of teacher directed exercise is nothing in the scheme of developing real skill.

If people were serious about this problem they could allow children ample time to play, learning about the world and their bodies as small animals are meant to, or if they insist on making everything into a subject, treat physical education as a core part of the curriculum, English public school style, where everyone plays team sports almost every day.
Do they actually need television?
One could just as easily the aim is to protect political graffiti. Especially given the actions of the founders during the revolution.

The choice of protecting money is a strategic one, not one of judicial sobriety. And as we expect from that kind of ruling, it falls exactly along the political lines of the appointing president.

It is an extrapolation to suppose the founders intended allowing every avenue of distribution regardless of outcome. It's just as (un)clear the founders would be appalled at the current tight feedback from campaign finance which in many cases is indistinguishable from bribery.

Virtually all (esp. consumer) devices assume 'normal' atmospheric conditions with 'normal' temperature ranges and 'normal' humidity ranges. As you start to go outside those ranges, strange things can happen. People at extreme altitudes and/or in extreme climates see this on some types of devices. It's not a big deal. If you have needs outside the typical ranges, you provide your specifications and be prepared to pay much more for your solution.
> As previously noted, O'Rielly's speech objected to municipal broadband networks enforcing Acceptable Use Policies that target "amorphous categories like 'hateful' or 'threatening.'" Yet O'Rielly didn't object to Comcast and AT&T enforcing Acceptable Use Policies with those same terms.

It's right to point out this nonsense, but in his defense, there is a huge difference between a private company "censoring" speech, which it can do, and the government doing so.

This is of course muddied by the monopoly terms that comcast and the rest typically extract from municipalities. So if we are to take O'Rielly's comments seriously, he should be emphatic that such terms need to be removed from TOS when users have no other choice for an ISP.
This is equal parts impressive and scary. It's awesome from a stability perspective, but I'm not completely comfortable with "dial home" functionality apparently being enabled by default in a database system.
This is hardly new. I remember collecting ebooks on 4chan circa 2005 via this method. The fact that it was a jpg allowed you to post it on the imageboard with the zip/RAR file therein containing a txt/doc/rtf of the ebook.
As a matter of fact, you can treat .ipynb notebook as data format (https://nbformat.readthedocs.io/en/latest/format_description...) and build systems that generate/consume nbformat data. Jupyter/JupyterLab are examples of nbformat generator/consumer. GitHub/Gist/nbviewer (http://nbviewer.jupyter.org/) are examples of nbformat consumer.
You can also go to Settings>Privacy>Analytics>Analytics Data and see some pretty specific logs on why things crashed or why they were slow. You can see if an app used too much CPU time, OOM kills (a.k.a.

I would also add two good reasons to stick with R: RStudio and Hadley Wickham.

In theory, there are Python and Julia equivalents to RStudio (JupyterLab, Spyder, PyCharm, Juno, whatever) but RStudio is just so, so, so good. A truly great piece of software.

And of course if you have a data pipeline type workflow, and it fits into the Hadleyverse paradigm and isn't too performance intensive, there's nothing better.

>and doesn't seem to have bothered to get the insurance

It might not be possible to get insurance that covers "voluntary parting" if all the companies are doing that (or asking for crazy premiums without this clause).

It's not irrational to take on the risk vs. buying insurance. His equipment is not that expensive (say, people renting out their cars on Turo are in a different league); it still might make enough sense to vet renters more and cover the risk out-of-pocket.
