I'm sorry, but no.

Here is a pencil. Is it taxed in both A and B? Now, here's another pencil, but it was made from recycled wood. Is it also taxed the same way in both A and B? What about C, which is another one of the USA's 6000+ tax jurisdictions?

Wait... did that state just declare a tax-free weekend for school supplies (Texas does), so should that item no longer be taxed for Texas residents? Does the tax free weekend apply to both types of pencils?

Wait... A city in California just decided that pencils are dangerous if kids run with them, so they impose an extra sales tax to discourage unsafe writing practices. How are you expected to know about this local rule if you live several states away? Normally, rules of nexus would exempt you... unless you are using affiliates to help you sell pencils. Affiliates can trigger nexus. How can you know the local tax rules for every affiliate that signs up?

And, sorry... if you think timezones are simple, then you are way off base. If it is easy, then it is because so many people have dedicated their resources to provide the tools to make it easy. (https://www.timeanddate.com/time/dst/events.html, https://en.wikipedia.org/wiki/Tz_database) Sales tax is much, much more complex (9 time zones in the USA vs 6,000+ tax jurisdictions in the USA).
I write Python in my day job, and I also experience a velocity boost by using Go. It's easy like Python, but the tooling is better. I really find myself appreciating the static type system catching errors at compile time instead of runtime. And the performance improvements I've observed for the systems I've migrated to Go is 50-300X.
Was just there on a weekend trip, while on longer trip to EU. (Got to love that in Europe you can just hop on a plane on a whim and be in a completely different country within a couple hours!)

Using the metro really reminded me how much LA is missing in terms of sane public transit. Walked around downtown Moscow, froze near to death (-12C with wind requires some extra cloths that I neglected), got into the first station I saw and only needed one train change to get to the line that took me home. All-in-all less than 20 minutes from randomly picked downtown station to home halfway across the city. Same thing in LA would have required extensive planning and likely multiple bus/train combos, or more likely a call to Uber/Lyft...

Another interesting feature is that Moscow metro has flat rate pricing.
No cultural Marxism is applying Marx ideas of class warfare to other areas. Basically, separating the population along an axis and calling one group oppressors and other oppressed. It haa nothing to do with changing the status quo.
I’m pretty sure this is already the case everywhere, but enforcement is impossible unless you already have some other registration requirement (like cars or boats) that lets the state know you’ve acquired something.
Dot has the arguments swapped.

I tried to get outlook for my work on personal device, wanting to use the app for push notifications.

They wanted MDM, I tried to deploy in my "secure folder"(formerly Samsung Knox), but would block my phone as incompatible platform.

They could enable this, but my company doesn't want to and no reason given
You can stash the stash but can you cash the stash and spend the cash?
Everything is a lock-in. :) Lambda has a straightforward interface so wrapping your functions in something else should be easy enough.
Is Cryptocurrency a form of entropy exchange from Energy (increasing entropy via heat) to information entropy (decreasing information entropy by hashing)?

I am thinking more broadly in terms of thermodynamics. I understand classical Thermodynanamics but I don't understand information entropy well.

From the standpoint of physics, Energy is the ultimate currency and it seems like we are trading it to decrease information entropy. Typically, entropy is the tax when performing work (for e.g in a heat engine) if that process is irreversible. I wonder if this kind of theory applies to Cryptocurrencies?
I recently learned a really fascinating stuff about semiconductors: as they heat up, the doping atoms tend to move, by diffusion. Heat = more diffusion.
This is substantially higher information density than anything I've read in the last week. Learning about triangular arbitrage programmatic trading alone looks like it's going to occupy most of the next few days for me.
That is so cool! I had thought of a similar system for blind people but someone had actually went out and built it already. I wish I could look at their source code as it seems like they are doing some really cool stuff under the hood
The death of outsourcing software
> Gamers are complaining about why can't nVidia just ramp up their production.

I don't see too much of that in gaming circles. It's understood that it would be risky as crypto will crash sooner than later. The anger in the PC community is almost exclusively directed at miners. Threads about it pop up on the daily, but what can we do? We could lobby NVIDIA/AMD to somehow implement restrictions on what the Gaming SKUs can be used for as they do with the Quadro/FirePro workstation cards, but it's unclear if that would work let alone if it's technically/legally possible.

It's a bad time to be a PC gamer, and just months ago it was a great time to be a PC gamer.
I ripped the MDM off my iPhone. Wasn’t worried about the, tracking my porn habits, just got sick of being forced to update my passcode every few months.

Fortunately (?) I can access schedule and email with iPhone app.
About a year ago I wrote a zsh script to analyse files in my collection and format/selectively re-encode them based on a set of rules. Basically, I wanted .mp4 files that the Roku Plex app could play back without having to do any kind of re-encoding (stream/container or otherwise).

That started me on a 2-week mission of understanding the command-line. Good God is it a nightmare! All my script was doing was reading the existing file, deciding on the "correct" video and audio track, creating an AC-3 if only a DTS existed, and adding a two-channel AAC track. It would also re-encode the video track if the bitrate was too high or the profile was greater than the Roku could handle.

Here's the thing that I discovered, as much as I swore at the command-line interface, I couldn't come up with a more elegant solution that would still allow the application to be controlled entirely from the CLI. Ffmpeg is capable of so much that figuring out a way to just "tell it what to do" from a CLI ends up with an interface that's ... that difficult to use. The program, very nearly, handles everything[0] as it relates to media files and simplifying the application to improve the CLI would necessarily involve eliminating features. It's one of those cases where a light-weight DSL would provide a superior interface (and to a certain extent, the command-line of ffmpeg nearly qualifies as a DSL).

[0] The "very nearly" was necessary because of the one feature I found that it didn't handle. It's not possible in the current version to convert subtitle tracks from DVDs to a format that is "legal" in an mp4 file because the DVD subtitles are images rather than text, whereas the only formats that are legal for the mp4 container are text. I found some utilities that can handle this, but didn't try any, opting instead to simply download them when I encountered a file with subtitles in this format.
We work primarily with small businesses in mental health, where a large percentage of devices are employee managed. The lack of attention to employee privacy with security needs in these solutions has been an ongoing point of frustration for us.

A carefully designed MDM solution could greatly simplify compliance and improve the security baseline for many of these businesses. As the market stands now, you either get easy to use with no safety rails on one end of the spectrum or all the power and flexibility and complexity in the world on the other.

I think there is definitely some opportunity in this area.
I use Samsung's knox VM thing. The corporate policy is applied only on the virtual phone that checks office email and calendar.
I would love to hear other applications of optimization techniques to HN readers.

(I used constrained quadratic optimization to fit transition matrices to population data for my dissertation, and for some other demographic estimation projects.)
The point of sales/use tax is that the tax on your consumption pays for the government services that you use.
1. spend 10 minutes playing with the kids
2. make dinner
3. Put kids to bed
4. Watch Netflix while doing dishes.
5. 30 minutes of DataCamp
6. 30 minutes of reading
7. Sleep
Does Your Gut Hold the Secret to Performance?
We decided to base our new platform on serverless - previously docker. Couldn't be any happier. Everything runs as expected and I don't need to worry about a tone of things.

People talk about vendor lock-in and all that. If you don't write things from scratch there is a vendor lock-in everywhere. Open source is also vendor lock-in. For example, we used to use xulrunner from Mozilla for some time and look where it is right now - nowhere.

I was also concerned initially with being locked in into a particular platform but then again, what I realised is that if your project is extremely successful you can always spend big to migrate when you have the funds to do it. As a startup, that is not the case. You start with nothing. So platforms like AWS are absolutely amazing because not too long ago you still had to buy your own datacenters.
Sales tax is and absurdity and needs to be replaced by property tax and income tax
Sad that Samsung EOLed their Knox ecosystem. There seems to be a market for it.
Though there is some benefit to cryptocurrencies that rely on ASICs for mining: it means that someone with a significant amount of CPUs/GPUs under their control (such as botnet operators, or government groups like the NSA) can't waltz in and trivially 51% attack the blockchain with their existing general-purpose hardware, and then go back to using it for other things. An attacker would have to commit to buying/building specialized mining hardware for the attack, and then that hardware can't be repurposed for anything else after the attack other than mining.
I wanted to buy 2 1080 for deep learning experiments, but that's going to have to wait.

I picked up a used 32core 128gb server for $1000 recently... It's only a matter of time before these 1080 will be sold for pennies on the dollar.

If your lively hood doesn't depend on it, wait.
A random country clearly has the power to ban imports. Would you prefer that over paying taxes?
NASA wanted to (or still) put a satellite at L1 point near Mars to create an artificial magnetic shield. http://www.popularmechanics.com/space/moon-mars/a25493/magne...
I wonder if they could cripple integer performance; this would prevent mining while probably not hurting gaming performance.
The Turing test is a dialogue. There is already tons of programmatic content on the web and it is indistinguishable from human-written content in the absence of contextual cues.
Those billions of dollars come from the USA, and the cartels only “earn” those billions in profits because of the war on drugs. Were they legal, their profits would be a fraction of the amount. When’s the last time tobacco or liquor companies employed assasins and private armies?
In California for example, there is a state base tax rate to which the county adds an additional amount along with the city you reside in. So there are hundred of sales tax rates depending of which city you live in.
I understand most people are wishful to see Cryptocurrencies crash but what if it doesn't?

What would happen if Crytpo booms big time?
Don't forget that the weak governments in South America exist in part due to USA interfere.
Twitter is a joke
What You Need to Know About the Congestion Pricing Plan in NYC
I like this answer. However, by solution space do you mean domain space?
I had a similarly pleasant travel experience while visiting Moscow on a whim. It was a bliss to get all around the city and back to where I was staying easily. Trains would come often and would have multiple connections (and if you missed a connection, you could just take one of the circle lines to get to the line you missed. And being from southern California, I definitely agree with your comment about how much more difficult a trip to LA would be without having access to a car.
I remember that this was a big deal when they introduced something similar at my previous company. It added something not mentioned in this article-If I recall correctly, it enabled IT to wipe your device at will. I declined.
“Over the past two decades, as the U.S. war on drugs undercut the cash flow of narco-traffickers, kingpins diversified”

Unsupported. The war on drugs likely increased the cash flows for surviving traffickers. Either way, diversification always happens when making massive profits in a capped or risky market.
To further complicate matters, not only my city, but my zipcode too spans two different counties.
Even in libertopia, there may be independent voluntary consumer protection organizations (not funded or enforced by the state) which sellers and buyers might associate with or otherwise utilize to ensure positive trades.
List of Blogs that brings out the Hacker in You
Hey Hackers,
This is Vijay, I am a junior developer from India and I have visited Hacker News regularly and often time I have found some blogs/websites that are purely Gem.

[Build your Own text Editor] (https://viewsourcecode.org/snaptoken/kilo/index.html)

The purpose of this post is to gather all the best blogs that all you Hackers knows about, no matter what it is.
It might be something related to ML, related to Entrepreneurship, Computer Science, DS or anything. The objective is to organize a list of blogs that we should visit and start Hacking on it in our Free time.

Some factors that I am including while listing the blogs.
1. The blog should be Hacky by nature. (Means it should have things that can be applied rather than theories. We should learn by doing not by reading)
2. Some exception can be made for Blogs that purely talk but I think as a person posting that blog you should also be responsible for the quality of that blog. For example Essays of Paul Graham can surely make this list. (The idea behind is it should appreciate the Hacker in you)
3. Limit the number of resources you are posting. Take a look at the list if its already there don't put it again.
4. It could be an interactive website/an online MOOC that you can follow through. (Limit the MOOCs that are pretty common for example fast.ai, Andrew NG's course)
"They have zero presence in mobile." is false: Infineon.
This is bullshit. I own my device, and this kind of management shouldn't be possible on devices that I own.

Can I run some sort of VM or a sandbox to make the server think they're MDMing my whole phone? I should be able to feed them enough garbage to keep the other end happy, right? If IT wants to be able to remote wipe my phone, they can remote wipe my VM instead. Anything less would be absurd.
In Russian culture, smiling at a stranger is considered buffoonish behavior.
ASICs are supposed to be orders of magnitude more efficient at their job than GPUs. So NSA can make a 0.01x the investment and "waltz in and trivially 51% attack the blockchain", all while not touching their existing equipment.
Land Value Tax instead of property tax. Prop Tax discourages owners from improving their properties because then they’d owe more tax. Land value usually isn’t created nor destroyed by the owner, so it makes more sense to tax it.
Burner androids are cheap.
Proof of work is about consensus among mutually distrusting parties. It has approximately nothing to do with entropy.

Of course there is some connection, but the simple "exchange" you're looking for does not exist.
This may be a dumb question, but at what point does a "machine" become a "robot"?
There are no ASICs for Ethereum.

Interesting, I had no idea. Do you think it's worth getting a CO2 monitor for a home office? I don't usually have the windows open since it's cold out. Is one person enough to elevate a small 10x10 office to cognitive impairing levels?
Hire slowly, grow slowly: how we grew from 1 to 100 employees
yEnc is very much designed specifically for Usenet though. It gets its low overhead largely from using almost all characters which aren't special in NNTP (and also adapts allowed characters depending on NNTP context), which isn't appropriate for many cases where base64 is used.

There's encodings which may be more appropriate, which use more than 64 codepoints, such as base85 (https://en.wikipedia.org/wiki/Ascii85), assuming that these are allowed.

As an aside, I've implemented a fast SIMD accelerated yEnc encoder/decoder here (https://github.com/animetosho/node-yencode), for anyone interested.
It sounds like you're just saying, "it's not too much of a pain."

The straps weren't the problem for me with swimming or camping, it was keeping the lenses clean and having a spot to keep them from getting crushed or scratched (the hard cases are bulky and tend to break after a year).

Glasses got way more annoying after having a young kid. They're his favorite toy and he has easy access when you hold him.
I suppose a mitigation might be a table of just (unique_id, partition_field) as arbiter of validity. Assuming such a table to be compatible with system design... one would need a whole lot of rows and/or heavy fragmentation to rule it out, no?
Simple Garbage Collector – Implementation
What is the basis for an overwhelming assumption on HN that Cryto will crash? I am genuinely curious. What specifics indicate that it will crash?
I mean given the source...
Just don't agree to it. Or remove the policy and state your concerns to your employer.
It's covered in the article: Different currencies use different hash algorithms. Ethereum takes a lot of memory (gigabytes apparently). No one's building ASICs with GB of memory, at least so far.
“According to the prosecutor the blurb of text does not change things for the second case. "If the text is misleading and is intended to buy low and sell high, it can be considered as a criminal offence", says prosecutor Jan Leopoldson.”

That’s a thin line. The intent of every long investor is to buy low and sell high. So any time an investor publicly proclaims their love for a stock they are at risk of prosecution.
Try looking at your receipt next time you go grocery shopping. Some things will have HST and others won’t! Now go to PEI and buy some kids’ clothes and look at your receipt. Next, go to a coffee shop and buy a cup of coffee... HST, then turn around and buy a bag of roasted coffee beans... no HST!
Wow. Thanks! Just one minute of each of the seven exercises has improved my vision to the point where I no longer need my 1.0 reading glasses to read hacker news on my iPhone 7+. The improved vision seems to be lasting at least a few minutes. Perhaps there’s truth to the “use it or lose it” theory of vision?
Just get a cheap burner feature phone for work. They’ll get the message. You might be able to use the same number on two phones on some carriers.
AMD APUs (and Intel+AMD Graphics APUs) might be what keep PC gaming alive for the time being. If AMD can pack a chip that can match an RX 460 onto a single die for something like $200 it'd be the goto chip for an entry level system.
Just a warning: article has LOUD autoplaying video that will start up about a minute after you open the tab in the background, just to fuck with you.
I am currently going through this book. Any advice on how to extract the most value out of it?
The only way to never sell out of bananas is to order enough that a portion always goes bad before selling. No matter how much sales you do, there's an inherent trade-off between the amount waste and amount of temporary sell-outs. That is a problem all stores have to deal with, and they have to choose some policy for it.

Similarly, stores have a policy about what to do when there is a sell-out (leave the shelf empty or put something else there).

Each policy decision has pros and cons, and no store is immune to these issues.
>> Proof of work is about consensus among mutually distrusting parties. It has approximately nothing to do with entropy.

Think more abstractly - at the end of the day, Energy is being consumed to compute some problem. That solution has intrinsic value precisely because it took energy to solve it. Extrinsic value is the market economy of CC, and that's where the 'proof of work' and 'consensus amongst distrusting parties' comes into play - that concept of a currency is only valuable if sufficient number of parties agree to its value. I am weeding into the underlying fabric that holds Crytocurrency together.

Imagine if Energy was free, despite of 'consensus', the supply of such currency would be virtually unlimited and it would be worthless.
Breaking embargoes generally leads to easy, packaged exploits appearing that many days earlier than they otherwise would have. Obviously patches being delayed gets you on the other end. How are either of those not a huge deal? Do you just think it's not important to have patched systems against published vulnerabilities?
Yep, Postgres grants flexibility (you can build temporal materialized views + other constructs some other database servers refuse as nondeterministic) but with the burden of having to refresh the materialized view yourself. This was a little bit of a surprise after doing materialized views in MSSQL and Oracle, which treat 'em more like big old indexes updated in lockstep with the base tables.
My 1975 bmw 2002 is my fun, weird weekend car. I bought a brand new daily driver in 2017 and bmws were among the cars I tested. I decided to get a fairly boring, reliable daily and the fun weekend car, but I seriously considered going with a single car, which would have likely been a bmw m235i. So, yes, I'm in very much in their demo.

As I said before, the actual money involved isn't what would turn me off. It could be $1/year and I'd feel the same way. It's the principal of being charged an ongoing fee for something that doesn't require it. I'm happy to pay to change fluids in car, or pay to get data over an integrated radio because those are ongoing services that require the service provider to invest in maintaining or offering a service. Having carplay continue to work after they build the car requires bmw do exactly nothing.

I have no issue with bmw charging whatever they want for people to get a leather wrapped steering wheel. They should charge obscene amounts of money if they can get people to pay. What I have a problem with is bmw charging me again next year if I bought a leather wrapped steering wheel. I already bought the feature, I own it, they can't charge me again. The fact carplay is some code and a security chip from apple doesn't make it different from a steering wheel. The concept of ownership is being eroded.
