Yeah; I'm quite surprised, particularly given both Google's and Microsoft's push into the education market, that there is still not solution for this. MS certain has the edge (pardon the pun) with its maths tools in Word and Onenote, but lacking on the web. And that Google has given absolutely no consideration to this with Docs/Drive and related tools means that my school can't switch exclusively to G-Suite, and need to keep MS tools (and have to deal with installations and licensing) around.

That was the exact point of the ASICBOOST FUD we've seen in the last week - to cast uncertainty and doubt. Taking a step back though it all seems like just the latest attempt to distract from real issues. ASICBOOST is just another optimisation from companies who make their living working on these kinds of things. It's been known about for many months now so the last few days just seem like a bizarre attempt to demonise the miners for doing what they do.
Consumer electronics have been disposable for 25 years now. You don't exactly see an electronics repair shop in every town anymore.
There are situations in which you want to just get a right answer and ship, like at an early-stage startup.

Then there are situations where the code you write must play nicely within a massive, already-complex system, wherein it will work with potentially huge inputs. Like at Google.

So, saying in a Google interview that you don't think Big Oh is super important, and that you prefer shipping whatever correct solution you come up with first and then worrying about efficiency if it ends up being slow, would likely not get you very far.
Foreign products arrive in a country at specific locations---most likely large seaports. Impounding and stamping these products as having X standard or Y standard isn't very different if the standards body is the singular federal government, or applying 5-10 different standards levied by states.

Also, even if there is a federal standard, the states themselves are always free to set greater limitations---for example federal emissions controls on cars, versus California emission controls.

The issue with silicon valley interviews is that it's leading a new paradigm of management styles that deal with knowledge and creative work

This shift MUST be accepted by everybody ornostracism is risked. (Like trump supporters)

But paradigm shifts take time and the majority of managers still want cogs. But instead of filtering dor cogs they have to dress the filters up as filtering for a "i give smart people freedom team" and the convoluted mental gymnastics needed for this creates shitty interview processes.

All "well this technique worked for us" stories are mostly Not useful because tehy are just N=1 stories about managers using their preferred filters.

The issue isn't with the filters themselves (all sorts exist) but with a culture that obligates everyone to out on false facades.

People who just want to be paid and can work well need to pretend to be passionate. Managers who want well-paid cogs need to pretend to promote individualistic thinking etc...
It's a huge barrier to market entry effectively making for a natural monopoly. In farm equipment it's John Deere and Caterpillar and they don't have that much overlap product wise these days.

> If you're using python, it can be the bottle neck

> data processing workload you need to do in parallel

It's funny how often those two go together, you're of course correct (for now). I never wrote that the language couldn't be the bottleneck, though.

If you are doing something that requires heavy parallelization then, by all means, don't use python or replace it if you're already using it... But that kind of workloads isn't actually a common (i.e. 50% or more of all applications) scenario.

> ...but basically, if you don't address the root cause of your perf issues (whatever they are), you're going to be patching and firefighting forever.

Yes, that's what I'm saying: Find the bottleneck and solve that. I was only addressing the, in my opinion, undue focusing on languages of the comment I replied to.

> quite easily

Only if one is working with poor developers. And this is true for all languages.
This video also caught my attention. The camera looks like a Canon EOS 600D and its priced at about 100,000 Korean Won. According to the XE Currency Converter, that is about USD765 [1] compared to USD400 at Amazon [2]. Looks like capitalism is alive and well in the heartland of Juche-ism.

I think we'd all be better off if basically everything was open source, by way of eliminating intellectual property protections provided by governments.

As an alternate solution, those of us with engineering skills can work to create an open source economy with open source factories, computers, and products.

This would never be a problem nor would it be likely to happen if genuinely competitive options existed for farmers that were not locked down.

Another way we in this community can help is by helping smaller businesses learn the value of open source and get them using and creating it.

I believe with a sufficiently open source base in our economy, we can make great headway into eliminating material poverty.

I write a little about this on my personal site, here:

I assume that's a 100mbps unmetered port, and probably not able to push 100% at peak times (over provisioned). How many of these would you need to serve the implied peaks that come with 70TB/month? And have them spread on at least 2 continents?
> Wouldn't you know up front when you're choosing a stack whether they meet your compliance demands?

The number of actors in industries with particularly notable compliance requirements (like HIPAA) that have internally very weak, inaccurate, ideas of the actual requirements and who discover the pracctical meaning of key elements both long after they've been in force and long after they've relied on an inaccurate understanding is, well, non-negligible.

Trump Is Giving Geoengineering Another Moment
There is an element of adventure to these pictures. Some of his pictures are clearly illegal, disallowed, or uncomfortable in the North Korean context. There are examples of these especially in the second instalment [1]. Having spent some time in small-town Russia, I could almost taste the soulless architecture. The sense of adventure is further heightened when watching vlogs from Jaka Parker (noted elsewhere here), including this one video of him travelling almost 200km outside of Pyongyang along North Korea’s major highway [2]. There are remarkably few cars on the road and at several points, it felt like B-roll footage from a movie set a-la The Walking Dead: the desertion in the roads of this nuclear power is simply astonishing.

On a related note, several tour companies across Africa offer overland tours including a 73-day journey across 10 countries in Eastern and Southern African countries [3] and a terrifying 27-day trip across the western edges of the Sahara Desert [4, 5, 6].

> Why is it that these farmers believe they have a right to modify that software?

Because a farmer in the middle of a harvest can't afford to 'wait in line' until the manufacturer or the dealership has time to send someone over to make a repair.

I've lived in a farming area and had a pretty good machine shop as well as a ton of welding gear and it didn't take long before farmers knew where to find me in case of a problem just to temporarily fix the issues they would encounter to be properly taken care of once the harvest is in.

The weather waits for nobody and losing a crop because of equipment failure can put a farmer out of business.

Right to repair.

The best outcome of all this nonsense could be that manufacturers of capital goods such as tractors are by law required to fully document what they sell including schematics, board lay-outs and source code or even a reproducible build package.

I'm on Ads and Commerce front-end, and I also know a number of people on Android. These of course are mostly constrained by users' devices, so don't have the scale your talking about. But I also think the trend you're talking about of smaller roles has been continuing and has a lot to do with it as well.
Greg, I think the recursive algorithm should still be faster on the left hand side than just rolling the coinbase extra nonce, but after the first sqrt the numbers are pretty small so maybe the constants dominate.
I was also confused about algorithmic skill and software engineering skills. But I got clarification after working in industry for a while.

1) Most of the software engineering work is product development, just wrapping already existing algorithm and optimized computer program into apis and test and maintain it.

2) There are very few software engineering work involving writing algorithm and optimized computer program.

One example, everyone here might have just used mysql database. But if you look into the code, you might see there are complex data structure, and algorithm are being used.

Its a good thing to solve these kind of algorithmic problems.

Or even basic electrical appliances. I have a toaster, a kettle and a vacuum which are all bricked because of peripheral failures - two poorly (deliberately..?) designed mechanical switches and a charger - which in many cases would cause the whole otherwise functional appliance to be junked. Only somewhat resourceful and stubborn folk like myself bother to fix these things themselves.

Puzzles are fun, but it's best not to put too much predictive faith in them, because otherwise you're just affirming the consequent. Exceptional individuals are quite likely to be good at puzzles, but you cannot (in my experience) assume that because someone is good at puzzles, they have actual skill in solving real-world problems. I've worked with too many counterexamples.

It's an element of all disciplines and, more charitably, one aimed at achieving two functions. One is to say "this is a paper from someone embedded in the discipline and who speaks the same vocabulary as you". The other is to say "and this is intended to expound on a subject parallel to X (or following on from X, as the case may be)"

You can argue that this class of jargon is exclusionary or not. Agre, at UCLA, for example took the position that jargon was inherently a tool of dividing up groups into "in and out" (ironically he himself, with an MIT PhD, was very much in the in group).

I tend to consider jargon just a tool like any other, typically valuable because you can save a lot of time and gain clarity by saying "O(n^2)" or "trie" and assume your reader understands it.
Right I'm not saying that python 2/3 doesn't have these abstractions (to be honest I'm not an expert in either Python or Go, I'm a C++/Haskell guy). Just that the author is creating an obvious false dichotomy.
Ask HN: How to potentially sell a bot to an organization
Hi Guys,

I am a fellow developer/entrepreneur, have been working on a bot that will help general public access information of this organization in a much better/efficient way (at least that is what I + people I showed it to claim).

I am in two minds as to whether I should release it, generate userbase and then approach the organization or approach them first. Are there merits in selling the whole thing? Lets just say the service this "organization" provides is high value and people use it on daily basis. In terms of what's out there, I haven't come across anything after extensive lookout.

I am just laying out my thoughts here and I am open to advice of any kind at this point.

Appreciate you reading :)
Over the years I have come to agree that "Laziness is the mother of invention".

If I have to do something more than once or twice, the first thing I think about is whether it is automatable.

One of the reasons I have always tried to stay close to the Unix view of the world is the access to simple tools that can be pipelined to provide powerful toolsets. I am a firm believer in the value of scripting things whether through shell scripting, awk, sed/vi, PERL (in the earlier days), Python etc.

The first thing I used to do when I get a Windows environment was to install cygwin or something similar that gave me access to Unix like toolsets. You may ask "Why not Powershell?" but I have been using Windows before the Powershell days and sometimes old habits are hard to break. The unix tools are almost near universal nowadays whether using Windows, Linux or MacOS/OSX.

Once you have acces to these tools simple repetitive/mundane tasks can be easily automated to increase productivity.
Easier to optimize than what? I used to work on manufacturing nuclear submarines. We built exactly 1 of many things. You'd think that would mean there was no repetition, but that's not the case. The processes are repetitive, even if the product is not. Everything can and should be optimized, that's the only pathway to higher productivity.

The result of a free market is that the better products will always win out. Then if the firms behind those products are well-run, they will use the dominant market position their products have granted them to try to raise barriers to entry and smother upstart competitors in their crib.

"Car company" and "rocket company" are interesting examples, since the "smart, passionate and dedicated entrepreneurs" in those areas needed billions in government subsidies to get off the ground []. And "computer company" includes the software side, with its low capital costs, and the hardware side, where the competitors are firmly entrenched (what's the last laptop/desktop upstart to hit it big?).

This assumes the trick is easily-indexed-by-name and can be looked up - so you have to know it exists. A lot of the better tricks are more like 'frameworks' whether specific ("Four Russians", "prefix sum") or general ("dynamic programming", "branch-and-bound").

There's a limit to how far you can get just Googling stuff ("how do I reverse a string") for recipe-book solutions to things. I think practically everything in Computer Science could be Googled ("how does merge sort work", "what is an inclusive vs exclusive cache") at some level but this doesn't mean one shouldn't know a great deal of it. At least, if you want one of these jobs...
Thanks for sharing these. They're fascinating.

In the winter video, a few things jump out at me:

- The environment seems depressingly spartan and utilitarian. Everything is drab. And yet this it he capital city.

- Virtually no one is walking with anyone else. There are a few exceptions, but it looks as if conversation is essentially absent when out and about.

- In a manner, it's boggling to consider where all of these people are coming from and going to. With no commerce, every building looks like it might as well be an apartment building. The feeling I get is like watching the rote movement you would see in a computer simulation of a city. A lot of movement, but with what purpose?

- Even though there is only very minimal traffic, it seems like crosswalks are not common, so the Youtuber keeps using pedestrian underpasses.
Well, in fact each state would and does need a parallel monitoring program, which inevitably would come with some duplicated bureaucracy. You can mostly skip the duplicated regulation process however.

How are you planning to interface with people in each state, in regards to community and business, as it pertains to policy changes and dozens of other scenarios (some of which may be limited to just a few states based on industry and environment)? There's no scenario under which you don't need to have parallel monitoring for every state.
> It selects for people who do well on the whiteboard under pressure

If this were true, Google would have crashed and burned a long time ago.

> what if interviews aren't even selecting "a" right person for the job?

We know that interviews are selecting a right person some percentage of the time. That percentage will never be 0 or 100. We will always have to accept some bad hires.

I would rather that successful hire percentage be somewhat lower and keep the team engaged in defining culture and hiring standards than to give up team involvement for a higher right-person rate.

My main point is that the people studying this issue and arguing against the interview process tend to only look at less than half of the benefit of the interview process. If we're going to ditch the interview process, whatever replaces it needs to have the same property of involving the existing team or it is, to my mind, automatically worse than what we have now. Because while we're all aware of how flawed the interview process can be, it does work to some extent. When I was hiring, only 2 out of the 50 or so that I hired didn't work out. Would I like to have avoided hiring one or both of them? Sure. Am I willing to sacrifice the team involvement benefits to got to do so? Absolutely not.
