Early Stage: Do you build fast or correct?
I'm having a disagreement with my co-founder. He wants to build our software using best practices which will double the time needed to build the MVP. I don't disagree with best practices but i'd rather go back and do them once we have a prototype we can present to customers/investors. It's not that best practices take longer to implement but rather we are experimenting and learning them as we go.

1) When you were first creating your prototype/MVP did you use best practices or did you do things wrong to go faster?

2) How did this impact your startup later on?
I agree that this article is talking about drones because it's newsish, where bribery and guns are less so.

But, that's not really how the economics of violence works. It's more of a whatever-works, and whatever you can get your hands on element. Guns, bombs, hard men, threats and bribes are still in use. Infantry still exists, even though ICBMs exist. They don't have to choose.

This is quasi military conflict we are talking about. Air power, however meager is a game changer in military conflict. At the fully militarized level, drones have seen a lot of use. They can be deployed everywhere that full air power is impractical, either for tactical or political reasons. A drone base can be orders of magnitude smaller than a traditional air base, even a floating one.

A 2kg payload (or even 200g) is enough to carry a grenade. Grenades kill. It seems likely that drones will be used this way.
You are not alone. The first thing I went to look for was an export feature. No mention of it on the landing page.
So increasing the wingspan means they can fly higher above the ground and clear more obstacles? I'm now imagining massive carrier-sized ekranoplans carrying shiploads over the tree tops.

There will always be fewer people at the top of the pyramid than there are at the base. As such, there will always be too few opportunities for everyone to grow and/or be promoted, especially not within a specific timeframe of a few years.

A company is not an ever-flowing pipeline up that pyramid, the job still needs doing. So it's normal that indeed people will leave to explore other opportunities in other places.

I'm not certain this can be resolved in smaller or medium-sized companies. The amount of opportunities tends to grow with the size of the company.

"The volume of data breached is currently unknown. Cyble claims that attackers have demanded 10 ETH, equivalent to USD 4,000."
—The attackers clearly don't know anything about Paytm. $4000 is likely their marketing budget per minute!

Seriously though, Paytm users have had to face fraud on their platform for so long (for instance, here: https://www.moneycontrol.com/news/business/all-you-need-to-k...) that I'm surprised they haven't got some steps in order already.

The weakest link in cybersecurity is the people though. And PayTM has a lot of them!
Always a cute example when people think we need to optimise for land for farming.

Not really, you can learn. I spent quite a bit of effort in my twenties to convert myself over to metric for heights, weighing food, measuring liquids and such (I'm from UK).

UK had been officially metric my whole life and EU were at the time mandating pricing in metric.

Supermarkets were very reticent to use metric - or at least flouted the regulation, presumably as prices seem lower in pounds (UK 'lb') than kilograms. Now I find they often don't show weights but hide behind pack sizes for fruit pricing; presumably to prevent customers comparing. They do still have scales but it's a PITA weighing half your produce.

Getting comfortable so I could 'feel' what a particular mass (and £/kg) of apples was, say, took effort for me. Same with heights, and shifting to using kg for person-masses too.
This is exactly how drones were used in Syria as I understood. To attack otherwise protected targets or strike fear.

The removal of incremental patching means most major updates are now secretly a reinstall. This has increased system stability - now patched installs and fresh installs are the same. The rebooting even for minor updates is due to files not being able to be changed while they're open, so a change to, ex, gdi32.dll is going to prompt a restart, regardless of the size.

The question isn't so much whether I would accept, but at what price I would accept.

If Amazon is selling their own stuff for Amazon bucks (and people still want to buy stuff from Amazon so that Amazon bucks have a non-zero market price), there's a minimum finite amount of Amazon bucks that I would gladly accept.

If Amazon bucks weren't very commonly used (think like bitcoin today), I would probably ask for a premium over USD just to make up for the inconvenience of having to exchange them.

If Amazon bucks were more commonly used in daily life than USD, I might even accept a slight discount.

> If you worked for amazon, would you accept amazon bucks as salary?

That's actually an even easier question. Amazon already pays their employees partially in Amazon stock. At a big enough stock offering (and frequent enough vesting), I'd happily accept an all shares compensation.

Now, Amazon bucks would be different from Amazon shares. But the only thing that matters to me when accepting compensation in shares is how easy it is for me to convert the shares (or bucks!) into something I actually want later.
>QM doesn't even pretend to tell us how reality actually is. That's what the various interpretations do

Isn't that backwards? QM, without "interpretation" tells what outcomes of experiments should be. That's reality.

The interpretations are interchangeable, so even if there was some oracle to tell us one of them was better, it wouldn't tell us anything about reality.
I recently started watching some metalworking videos, and Americans in those use 'thou' (more confusingly aka 'mil') - thousandths of an inch. That seems mostly fine to me, it's a different scale, but whatever, it's just as sane if you don't need it to interact with volumetric measurements etc.

Woodworkers obviously don't need or want the accuracy of the 'thou' digit, but it seems to me that similarly normalising on decimal fractions and using 'huns' or 'around 12x thou' would be an improvement.

But then, they're used to it and happy with it, it's only viewers like me who aren't that are thinking about it!

(I'm British, so use Imperial in some contexts, including casually sizing small things in inches, but probably never fractional other than 1/2".)
THat's probably the best fucking explanation in a HN comment I have ever read. Mind expanded. I actually feel like I get this stuff, which I didn't study at college, a little bit. I took chem... physics always seemed impossibly strange.
it's an algorithm for projecting data to lower dimension. I.e. you have an Excel sheet with 20.000 lines (representing customers for ex) and 200 columns (representing blood pressure, height, weight, etc).

What you want to do is "visualise" those 20.000 points in 2D or 3D so you can get an idea of how the data is distributed. So you use t-SNE to "compress" those 200 columns to 2 or 3, and you display that.

Traditionally you would use Primary Component Analysis, but that only uses linear projection, and will not be able to project data that has non-linear relationships in the distributions.

Another algorithm, sometimes more powerfull and scalable is LargeViz.

I understand this inertia, but I have also worked in remote teams where you can just jump on a call instantly without any friction and equally end that conversation in under 30 seconds.

Zoom is a little clunky for that - if you have something like whereby.com you can have a named room for yourself so you don't even have any friction to find a virtual place to talk because it is preestablished which really makes the talk feel serendipidous.

With push notifications on rooms, team members can pile on a team room if they are free and watch to listen in in case it's interesting to them. Equally with push notifications people can come to your room if they're looking for you.

But it's also a lot less intrusive than a phone ringing. If you know the room people are in a call in, you can interrupt them (because sometimes you do need to get hold of people right this second).

It can really feel like the low friction parts of an office with the right mindset and buy in. Obviously there are pros and cons to having that low activation barrier but I find them a net positive overall.

It really can be as simple as "hey can we chat" or "@team - quick call?" and then drop all the formality of a meeting and approach the call like as if you walked up to their desk to say hi.
I guess so, yes. This comment from Zawinski is very old by today's standards, and Linux has made massive progress when it comes to usability. A child should be able to learn it quickly.
You can efficiently read 256 Byte granular data (4 cache lines) with Optane Memory (due to checksums). I think it makes much more sense to read/write fine granular changes for instance at least align pages to 64 or 256 Bytes instead of 4kb pages, where you often times first of all write too much data and secondly you pollute the caches with probably unnecessary data. There's a paper about how to add cache line aligned mini-pages (16 cache-lines): https://db.in.tum.de/~leis/papers/nvm.pdf

Want the esoteric explanation for 5280 feet in a mile? From my favorite book ever, the Quadrivium [1].

5280 feet in mile = 10x11x12x13 - 9x10x11x12 feet

Radius of Earth = 11x360 miles

Radius of Moon = 3x360 miles

Radius of Earth + Radius of Moon = 1x2x3x4x5x6x7 = 7x8x9x10 miles

> the point of short functions is abstraction and comprehensibility

If you have clean code style short functions you get nothing of that. There you split functions into more functions just for the sake of it. You end up with function names that describe the code worse than how the code describes itself, similar to comments beginner programmers make. Why is a comment "Increments i by one" for i++ not ok, while a function "incrementIByOne" is supposed to be good style?

Even if you don't make functions clean code-style ridiculous short, abstractions still come with a cost. You have to do weigh costs and benefits each time.

> 2020 was that there is no evidence that masks are effective, at all, against the spread of infectious diseases.

No. The claim was that masks were effective only when used by trained hospital personnel, which is still true. It was not clear if they would be effective when used by non trained hospital staff, and it was also not clear if non n95 masks (like cloth masks) would be effective at all. Once it was determined that they were effective, the advisory was changed to reflect that.

There was no backpedaling, only an increase in understanding which resulted in an update to guidance.
I have recently switched to Linux (ArchLinux)[1] after a not so happy ending with macOS. The new features that Apple keeps adding to macOS helps no developer and are consumer-oriented. I feel this is the new direction they are taking. As Apple gained momentum in the smartphone space, they want to capitalize that on the laptop market. And what's better than giving your users something they are already familiar with: iOS.

So macOS is slowly drifting to become iOS. While this might be good for your average consumer as she'll be comfortable manipulating the same patterns of the interface, for the developer it means less performance, less customization, more gatekeeping, etc...

In the future, I think there will be two types of OSes: A developer OS (probably a custom built Linux for the developer or the company) and a consumer OS. The divergence will be big enough that consumer OSes can no longer be used to do any useful programming (aside from programming for the said platform).

You're basically implying that a casual observer would look at AES all by itself and then say things are good. And I think you're correct to imply that.

The client IS paying for that; the trick is to not end up in a situation where a refactor becomes a rewrite but part of your daily job. A refactoring shouldn't take more than a couple of days; if it does, it's too big. Same with testing.

The client does not pay for refactorings or testing, and your manager shouldn't be made aware of it because it's part of your regular job. If they have so much insight in your day job that they start complaining, they're micro-managing and probably redundant (if they have the time / energy to look as closely at you / your team's work).
I have been upgrading (and porting to new machines) a Mac account starting in 2008 on a white macbook (2006?), transferred to a 2009 iMac, and then transferred to a 2017 iMac. Never had issues until Catalina.

Catalina finally made me do a completely fresh install with transferring data files as the only touch from the old system. Since the fresh install, it has worked perfectly, but before that the system would randomly keep repeating the last typed character. I could not live with that behavior.

Also got a new MBAir 2020 (Catalina) and that has been perfectly fine and solid as well.
At some point all measurement systems come from regulation. After all, that's one of the roles of a functioning state: provide a stable base for ownership (requires measuring surfaces, for land and buildings) and trade (requires measuring a ton of things, weight, length, surface, density, etc).

I'm incredibly careful with all my projects when it comes to security or avoiding bugs in general. It's only been after a decade or so working in my field that I took on projects where I had to write authorization/authentication code, or where I had to harden and manage a server.

Every single time that I took on work as a contractor for "Serious" BigCo, I was shocked by how much worse they were handling all of it. Literally no exception. For some of the chaotic startups I worked for, I wasn't too surprised, but this was the norm everywhere.

For example, as a contractor I'd be able to take entire continents' high-traffic websites offline for a particular media company, probably costing them a noticeable amount of money. Not only could I do this, but I could still do so more than a year after I had left the company.

I suppose having the resources to open up a can of lawyers makes a big difference though. So I'm still very careful personally.

I always wondered about the "computability of the universe" and its compressibility.

If the universe is actually compressible, then object permanence may actually be a trick, like it is in video games. Objects are generated on demand and deleted to save space and processing.

If it's not compressible, which is where I lean, then the full universe must be fully computed every time. No savings can be made, and any delay in computing an object might propagate and cause recalculation cascades for other objects. I lean this way because from my layman's understanding, quantum mechanics act similarly to random seeds, which increases entropy by a lot.

If it's not compressible, then the smallest computer able to simulated the universe is at least as big as the universe itself.

> Now I find they often don't show weights but hide behind pack sizes

Not legal, btw, unless you mean e.g. 'Lemons £1 (12p/ea.)?

The usual complaint is that the denominators haven't been standardised, so you might get A selling lemons /ea. and B selling them /100g.

But then, when they are literally sold as a number (or a rough number) in a net, as opposed to being weighed and stickered, even if there were a /100g (or whatever) price, it'd be +/- 10% or something. (That actually is standardised, that funny 'e' symbol for net weight, but the tolerances vary with nominal figure, so I'm not sure off-hand what it is at 100g.)

Well, you could just use the first few primes multiplied together as a base. 2 * 3 gives you base6, 2 * 3 * 5 gives you base30. Neither commonly used system does that, base12 uses 2 twice, base10 skips 3. So from a divisibility PoV both are lacking. But arithmetics is base10 anyways, since thats close to the average number of fingers for humans, so...
