China removes the fantasy layering of technology of the west, and bares it for what it is. Cheap plastics.

It always amazes me to see tech in scale sold for a fraction of what I thought was possible.

> But if decentralization doesn't matter, then what's the point of these technologies?

I don't think "decentralization" is a good term to define cryptocurrencies like bitcoin or ethereum. There are lot of properties in these systems. For example limited supply, untamperability of history, irreversable transactions, permissionless use etc. You can compare to older systems offering similar features and how well these systems work compared to them.

Transaction capacity & speed is most often not the primary point of blockchain systems, somehow many seem to assume that. For example it is no possible to create truly irreversible transactions in centralized system, since centralized system is always prone to forceful intervention.
> There was no central entity mandating that everyone was required to run the "new" network

Is the choice to run a less valuable network really a choice?

Remember that the foundation people gave themselves most of the coins that will ever exist before the network was even started, even if a lot was sold long before there was a word for ICOs. Only ~ 20% or so of the supply will ever be mined. It is not economically rational to differ in consensus rules from the foundation.

Delegation does not require sharing private keys. Nor does it require transferring XTZ to anywhere other than your own wallet. Ever. Period.

The only risk associated with delegation is that the baker will run off with the baking rewards instead of distributing them. Of course, the incentive is low since this can only be done once. The community is active is discussing the trustworthiness of bakers (which, to date, has been pretty much all of them).

The staking risk (risk of losing a bond) is entirely on the baker. This incentivizes them to make sure they're not double baking or otherwise running misbehaving nodes.

To what extent is this impressive feat and the global praise of it contributing to the repressive, genocidal government's hold on power?
It's also a culture thing. In Japan every supermarket and convenience store sells a lot of high quality fresh food (sushi, onigiri, a lot of different bento) that is meant for same day consumption. This only works because a large part of the population actually buys that kind of food for the same day. The shelfs are mostly empty in the evening. I went home empty handed quite a few times when waiting for the reduced prices one hour before shops close.

I agree. Any article (like the linked one) that states one side of a case as an absolute without giving any exceptions or caveats is going to be greeted by me with scepticism. Particularly as he keeps mentioning 3 large engineering organisations that disagree with him.

These specific batteries were terrible, I had one replaced and the replacement went to unusable in a year. Apple stance is that that is normal. Unfortunately the law does not provide for warranties for parts that are replaced for free.
The irony wasn't lost on me. It's a fine line. Let me try a slightly different approach.

When I blog I've had much better luck telling people "here's what I did and why". I don't know your circumstances and can't tell you how to solve your problems. You may need to choose different trade-offs than I did. With that said, here is my problem, how I solved it, and what I learned along the way. Hopefully you can learn from my experiences and make a more informed decision for how to handle problems you may encounter.
Jacobin is really good and Catalyst, its long form companion publication, is even better.
They're certainly surprisingly radical for the US; they're "leftists" in the European sense (not in the US sense, where a light-pink centrist such as Bernie Sanders is seen as some sort of rabid Bolshevik by many).
You could probably easily build a rig like that with a laser pointer and two servos, you don't need an extensive electronics background. The sample code put there would get you pretty far.
I found it noticeable at first, it left my eyes feeling slightly tired and “scratchy” and the flicker was particularly noticeable in dark environments with low brightness (which probably makes sense, I guess the “off” part of the duty cycle is longer at lower brightness). I don’t notice it at all now, though I can still spot it if I look for it in a dark environment.
The origin of money itself is deeply rooted in proof-of-work.
Lagrange points are found near any couple of large bodies. They are points where a smaller object will maintain its position relative to the large orbiting bodies.

The Chinese relay satellite is orbiting the L2 point of the Earth-Moon system. That is beyond the Moon on a line which goes from Earth to Moon. Hence, this L2 point orbits the Earth like the Moon does, and the whole system orbits the Sun as well.

Now if the spacecraft would be exactly at that point, the Moon would be blocking communications between the probe and Earth antennas. So instead, it follows a halo orbit which is quite stable around that point, but goes over the Moon horizon so that there is always a direct line of sight between Earth and the spacecraft.

Not a stupid question at all !
One glaring omission of the monorepo design, not sure why really, is if you want open and closed source software in the same monorepo, it doesn’t seem possible. Curious as to why this design choice was made.
You Know What to Do with Your Life, You’re Just Not Doing It
Anecdotally - I worked on a ~1 million lines of C project in SVN for a number of years (it was a Bluetooth stack). SVN handled it (mostly) fine.
Some people use the university not only as an opportunity to learn but to nurture friendships and connections that last for life. You are only young once, why you have to hurry to jump into the rat race? Especially someone whose identity is so tied with their ability to "be a good programmer" it might be a great chance to digest new perspectives towards life. Also if the bachelor level courses felt too easy you should probably haven take some master's level stuff.

The most annoying type of people in CS studies I encountered were those who thought they "knew it all" yet in fact, in the large scale, they knew very little. And whatever knowledge they had they often communicated poorly, perhaps disparaging others for not knowing what they did.
Coin miners use lots of electricity and release a lot of heat.

Electrical heaters use lots of electricity and release a lot of heat.

Would it be viable to start a company that sends attractive-looking coin miners to people who heat with electricity? Have the coin miner subsidize 25% of the electricity consumption as the icing on the cake.

Would the numbers work on that? Heating is mostly used in the winter. However, some people also heat water year-round with electric heaters. Miners get significantly cheaper energy and free co-location, at the expense of lower amount of total mining per year (as the miner would not be mining when no heating is needed) and increased logistic costs. An added bonus is that it completely nullifies the "wasted energy" argument.
Why would those things be issues? At Google there multiple new commits per second and it works mostly fine, you just need a VCS which is made for a monorepo.
> It's not that much of a minority opinion, it's shared by all Bitcoin maximalists

That's perhaps the least useful pejorative ever invented.

It's been a trivial observation from the start that if your problem is adequately solved by payment service backed with a traditional database then that will always have lower operating costs. (This does not mean blockchains are useless, but that there is a natural limit to their usefulness.)

Lately that's enough to get you branded as a "Bitcoin maximalist", which is more than a little bit silly.
But if the prof doesn't have a budget or billable cost-centre you're just going to shrug and he's back to 'do it myself'

That's the most common problem users have with IT.

Yes, this is more or less what I found - a reasonable number of implementations of apps which can read/write a keepass database, but sorely lacking in all the nice bells and whistles features that I like in the Android app.
That was one amazing answer. I can’t believe how much you taught me in so few words. Thank you very much.
Having worked with some organisations building on Android (>1,000 repos), life is not easy when you are trying to build on top of it and regularly take updates etc.

I asked one company how many changes required changes to more than one repo and was told "a small percentage". We then did some basic analysis of issue IDs across commits and discovered that it was in reality nearer 30% of changes. Keeping those together was just plain very hard.

Start to scale this by teams of hundreds or thousands of devs and you get a lot of pain.

Managing branches is also hard - easy to create (with repo tool) - but hard to track changes.
The grandparent's joke misses the mark, though. It should have been "singularity is now used for science too!" to make it work. As it stands, he just piled on to the expected list of benefits of singularity without the necessary subversion of expectation.

I wonder if this loosely follows the whole Dunning-Kruger graph: https://i2.wp.com/thephysicianphilosopher.com/wp-content/upl...

Except when you're young you're full of confidence because you know you're good. It just takes you ten years to realise that in order to use it efficiently you have to learn how to get the most from others / let them get the most from you? By the time you're in your 40s/50s you're coming up the other side - still just as talented, but now you can work with people as well?
This is the approach taken by a number of projects. The ones I am most familiar with are the OpenEmbedded/Yocto/Angstrom family that build Linux for embedded devices. They have a 'root' repo that references the layer repos (using metadata files rather than submodules), and there is a tool that does the pulling. It's optimised for pulling not committing though, I don't think the tooling helps much with bumping versions.

It can be misused though - the releases of the root repository reference the children by tags usually. Someone retagged a child repo and we suddenly had build failures.
Thanks

First: Grow up throw-away account, you don't need to add FUD know-it-all, jackassism. It's uncivilized and substance-free. You can sign up under a legitimate handle and behave along the intended guidelines, or go somewhere else.

That explains the move but not mandating explicit verbosity for a common case. Pony, for example, has consume to end the lifetime of a variable, .
Even good old C includes several functions that seem "redundant" at first glance [0] but are necessary for edge cases. I suppose this is similar to mechanics like fused multiply-add [1].

If predictors state their confidence and make falsifiable predictions then they can be fairly graded and compared. This is especially true when many other people are also making predictions about the same event.

Cringely is the stereotype of the pundit who makes a lot of really confident predictions that are just absurdly, comically wrong, over and over and over. But he's fun to read, so he gets read. Same as the analysts that you see on the news.
There may never be another "iPhone" or Smartphone market. I am not aware of any other product in human history that has access to near 80% of adults in developed countries, and has a replacement cycle in 2 to 4 years. I don't think AR will be it, I don't want Glasses or even Contacts Lens.

There aren't any more ground breaking things left. I mean even the iPhone concept goes back as far as Newton. What Apple needs is to slowly grows its user base in key market like China and India, while tries to not lose market usage shares in others.

I have always wanted or argued that Apple should roll out its iPhone upgrade programme worldwide. And has payment terms from 24 months and 48 months. By default it should include Apple Care+ and iCloud Backup Storage, and allow its customers to upgrade one year before their programme ends. Further locking them in to the ecosystem. Apple has plenty of cash and the spread out payment would not cause them cash flow problem, which only a few company on the smartphone market could do. Customers could also choose to add Apple Music, Apple TV or Apple Magazine to their Subscription. Using payment through Apple Pay or Apple Cash ( Which is still not rolled out outside US ). And all customer had to do is to choose their Network via eSIM.

There is no reason why Apple Pay can't be the central services to pay everything from electrify bills, water bills, mobile bills etc. And has a non cloud / on devices Financial Planning shown on my phone. Monthly spending etc. They talked about getting rid of Wallet, but 4 years have passed since then and they have nothing to show for. What cant I get rid of my loyalty and rewards cards? ( That is only just happening in Japan, and likely take a lot longer worldwide ). Why I still need ATM cards to get cash? Why aren't Apple actively working with banks to give me an option not to carry it?

7 Years since Steve Jobs passed away. The first four were still OK, up to iPhone 6s. But there has been clearly a lack of progress on many front, all while they were breaking records and earning more profits years after years. For the past three years I gave them benefits of doubt since they were too focused on Apple Park. But 2019 may likely be the last year my patients wears off and think Apple is no longer the Apple it once were. Actually Steve Jobs kind of predicted this:

“they cared about making a lot of money… they got very greedy and instead of following the original trajectory of the original vision which was to make this thing an appliance and get this out there to as many people as possible, they went for profits, and they made outlandish profits for about 4 years, one of the most profitable companies in America for 4 years, and what that cost them was their future, because what they should have been doing was making rational profits…”

Yes I think so too. But of course, as the article points out, nothing is entirely free. At some point we will have to build tools to handle scaling, and then the trade offs between a mono and polyrepo becomes less obvious. I'd lean towards monorepos as a base either way, but given sufficiently well working tooling it might not matter much.
It is entirely optional. I use Rust for two years now and work on a few things (biggest one around 10kLOC). I didn’t even read the Macro section in my books yet. Because I didn’t need to.
What is the "replacement"?
Not always. It makes absolutely sense to have a repository for the gui and one for the server.
When writing a new feature you usually write some gui code and some server code and create different pull requests.
I think monorepos are seriously wrong and I completely agree with this article.
Is there a privacy friendly analytics tool that does not set cookies and store data Forever? I don't really care about perfect user analytics, just good enough. Maybe by analysing logs. In the 90's there was s lot of good tools like this, but now everybody has gone cloud. I can't imagine the tools offered today are compatible with GDPR.
You can make a campaign to hire full-time developers from the outside then. It is just less money available for personal donations rather using collective campaign for one organization. See Krita as an example.
I decided early in my career to specialize on a technology stack so I could generalize over the entire stack. About a decade ago I got my first job on the Microsoft stack, and since then I've done 98% of my work on it.

It has it's disadvantages I'm definitely looked at as an old fuddy duddy because of my language choices. I'm pretty locked in, so if .net dies I'm gonna screwed while I come up to speed on the next big thing.

But it has its advantages too. I'm able to go deeper on a bunch of different parts of the stack than I would if I were having to jump around more. Web, desktop, services, database, mobile and even vba in Excel. There's no way I could be as proficient across the stack as am if I had to be proficient in different technologies. And it's allowed me to feel pretty confident addresssing any business problems as long as it's on the right stack.
The balance is between Moon and Earth gravity. However it is more subtle than that at L2 as both gravitational forces are in the same direction so they don't apparently cancel. The way to see it is to realize that L2 is relatively stationary to the Moon but not the Earth. As the L2 point is farther away than the Moon but has the same angular velocity as the Moon, Earth gravity alone is not able to keep any object at the L2 in synchrony with the Moon. One may want to recall that Earth gravity is just right for the Moon in its orbit so any satellite further away will have a longer orbital period than the Moon. The Moon gravity therefore supplies the additional force needed to keep an object at L2 orbiting the Earth in synchrony with the Moon. This balance (Earth gravity + Moon gravity = centrifugal force) determines the location of L2.
Thank you for taking the time to explain. Very helpful :)
If it's not at scale, is it even a monorepo? It's just… repo??
