ImpalaPay Limited Is Set to Build Africa’s Largest Digital CryptoBank
ImpalaPay Limited started it’s journey back in 2013 when business in mobile was beginning to outpace agent based money transfer business. Mobile money had just began to take off especially in East Africa and significant digital support ecosystems were growing.
The initial plan was to develop Money Transfer Software platforms and POS Switches for Banks and Non-Bank financial institutions and as we progressed we discovered a trend on the platforms we had built. It is here that we found a niche. Trade between African countries was growing and there were significant transactions from neighboring countries that matched those from Africans in European diaspora.

Over the years we have not only been developing and improving the platform but also increasing customer acquisition and raising our brand awareness. By January 2017 our platform had over 24 Million users to have transacted over our switching platform which has facilitated over 800 million transactions. Mobile money interoperability has given us access to over 200 million mobile wallets and 600,000 payout agents.

ImpalaPay has built a unified, secure, trustworthy and transparent financial network on blockchain which is set to disrupt the highly fragmented and regulated financial service industry’s numbers. It is Incorporating Virtual Fiat, mobile wallets, crypto and card payments, merchant mobile point of sale systems and financial applications into the largest online and offline blockchain cryptobank, with OTC exchange platform linked to major crypto exchanges.

The banking platform will be available online on web and also as a mobile application. We are in the final stages of raising funds through an initial coin offering of our utility token (ImpalaCoin) whose value will be determined by our financial network and Venture capital. The funds will be used to acquire the required regulatory licences in order to launch the app to the public. Some of the funds will be reserved for liquidity purposes.

Marriage requires commitment from both parties. You can still have that commitment even if you are marrying for love. If you and your spouse are prepared to sacrifice, you'll have a very rewarding time.

The real challenge is now days we don't encourage commitment, and your commitment alone won't make a happy marriage (e.g. it takes two for a happy marriage).

I agree that we need to de-stigmatize divorce that gets you out of a bad situation.

Edit: To say that since we marry for love so we should divorce for love does a disservice, namely because a marriage with two committed people is far more rewarding than one that only worked because of the initial fire of love.

Pointers require a very clear mental separation between the thing and the location where the thing is stored. However, in C the thing is only really identifiable by the place it is stored.

My impression is that income tax is less damaging to investment than than corporate taxes and capital gains taxes, while also being less regressive than a sales tax or VAT.

China is an interesting case. Where they are not enforcing it in a strict sense, but at the same time they are not completely leaving the regulation on the book. So the end result is a system that selectively enforcing its own regulations. In short, everyone is violating the regulations in some sense, but if the government doesn't come to your door, you are probably fine. But they would start campaigns now and then to check upon on you, and once they do, and you are not prepared, you probably will end up in trouble.

I too wonder how well such system works, but I guess China is in high growth mode for many many years, and we all know that growth can cover up problems. Once it slows down, it might be the beginning where things start to get interesting.
You get an error if you try to call an ES6 class as a function (without 'new'). So just try to do that inside a try-catch. If there is no error you know it is not a class and you have the result of the function already. If you do get an error and you know it is a function you know it must be a class.
Reminds me of the math lectures during university:

"Since we all know that ...
it is obvious that ..."

and I kept thinking "no we don't and no it isn't"
I'm not really convinced of this argument. A complex process like building a car will always have a bottle neck. If I recall correctly, with the model 3, the first bottle neck was battery pack production, then it moved to assembly and more recently it was painting. Axiomatically once you've solved the current bottle neck then the next one in line becomes the priority. (There's a book called "the Goal" that makes this all pretty clear).

So it's a never ending process of 'wack a mole' as production gets better and faster and cheaper. I don't see any sign that this process has reached a plateau yet at Tesla. If and when it does then sure start OEMing your components.

They've doing some of that pretty much since they started so it's not like it's a new concept at Tesla.

Actually, the gov is taking actions and it's quite strict. One example is, my friend's bank account was AUTOMATICALLY withdrawn a couple hundred RMB from last month, to pay the tax AUTOMATICALLY.

While a lot of these offerings are subpar compared to their competitors. I think one big advantage AWS has it that I don't have to talk to a sales team to get something working. Like, go to Confluent's site. The business plan is request a quote; I am not a fan of this model at all, why not keep things self serve and pricing open. This makes your bootstrap time significantly longer.

Also, with AWS's offerings you get better management with security groups etc.

Is there a valid use case for doing pointer arithmetic on a void pointer? It just seems so disgusting on the surface. Did someone just really not want to bother casting to uint8_t*?

As for the array types, I think maybe the article is really trying to say that they'll all compile down to the same thing in the end (probably...compilers can be weird sometimes).
Transpiling ES6 to ES5 is a hard problem, and I believe it's impossible to be 100% correct unless you ship a full JS interpreter written in JS (which would have terrible performance). As a result, Babel and TypeScript both have to make pragmatic tradeoffs, and you can certainly find plenty of cases of non-spec-compliance if you go looking for them. Sometimes transpilers diverge from the spec for performance reasons, sometimes because following the spec would be too hard to implement, and sometimes because there isn't any (reasonable) way to follow the spec. This is especially true with low-level reflection operations like seeing if something is a class or a function.
I wonder how much better off students would be if the majority of the formal CS classes they take are replaced with more traditional (applied) math classes for that reason. I seem to rely on ideas from those classes more than the ones from my CS classes when I write / reason about code.

Nope. Practically gcc and clang are available for all platforms, and for the rare cases someone uses another compiler or an old version you ifdef it out with the slow path. even ICC has the add/mult with carry overflow builtins.

The ISO C standard is hopelessly behind for decades. They don't even define a proper (unicode) string API (search, norm, utf8, fc) , constexpr, a memory model, ... and leave everything to the implementors.
> Where does the government's money comes from

Looks like many people are interested in this. Combining some information from Chinese websites, the main sources of Chinese government includes the following:

- Tax income: The top categories of tax income are value-added tax and business tax.

- Operation income of state-owned companies.

- Income from state-owned properties. e.g. A chunk of income of local governments come from selling lands to real estate companies.

- Government debt.

These may not be super accurate, but just to give an idea.
Because in a competitive environment, any value that can be sacrificed by one party to briefly get ahead of their competitors, will be sacrificed by everyone. That includes "quality", "correctness", and "not lying about it".

Developer on Call
The backed's job is to give the frontend what it needs, so at some point it has to make the objects that the fontend will consume and instantiate. That point at which the two realms join is a source of lots of potential reuse, from model objects, to the business rules surrounding their use and structure. Also consider things like validation, javascript-driven server-side rendering, etc
No. The 66% includes tax evaders as well as those who legally don’t need to pay.
> my friend's bank account was AUTOMATICALLY withdrawn a couple hundred RMB from last month, to pay the tax AUTOMATICALLY.

That's just the primary way to pay income tax in China. People usually don't file tax returns on their own. Their employers calculate the tax they should pay and deduct from their salary automatically
50/50 taxes/paying for who? Someone who makes $30k and someone who makes $300k might both only eat $10k of food a year, would the tax be a flat fee or a % of income?

If it's a flat fee, it could be done as a business, akin to how costco works where they wholesale you food for a membership.

In China, there is no property tax either. HAHA.

A lot of differences between US and China.

2% pay the income tax is because the income is really low, that is why the jobs are moving to China. The US is losing jobs only because US labors are paid too high.

In my opinion, it is just due to economical stage and structure. China's salary is rising, so a lot of jobs are moving to other countries, like Vietnam.
In the future, China government would more rely on income tax like US. But it would take another 15-20 years in my opinion.
So if government can change my private keys, this is no longer decentralized system. How is it different from current system, where county office has a big database of all the documents?
More the latter, but it’s a bit more nuanced: It’s more honest to say the each of us values a select few others (for me, maybe a dozen) and everyone else’s life I don’t value.
Agreed. Plus many six figure salaries are attached to equal or greater amounts of equity, 401K match and typically low cost health insurance. So while it’s not jet-set wealth it is more than enough to have a very comfortable life with few things out of reach for you.
Exactly.

People forget that high levels of income tax in the western world is actually a fairly new thing.

Denmark for example introduces income tax withheld by the employer in 1970 (kildeskat).

Before that the situation looked much more like China today. And the size of the Danish public sector was much smaller.

Tech shops say their work is too boring and you'll leave them; if they don't say that, they think you played games all day and suspect you do not have a serious work ethic. When I left the games biz, I had to hide my time there, describing the years as embedded software development. (I was an OS Dev for the 3DO, then OS dev again for the first PlayStation, then lead for a decade after at places like EA & Sony. I finally left for VFX, but that took two career turns to get there.) In general, games are only now getting professional respect.

I don't understand how "React/Vue/Angular" is considered "an entirely new language." I use React primarily, so I'm going to speak from knowledge of that. It is very obviously a framework and it does one thing - handle your view.

Depending on what you are doing, you may have very little react-specific code in your application.

You have data fetching, caching, persistence, authentication, tons of things, not to mention business logic that needs to be implemented in just plain Javascript.

Then out of that process you may have workers or other async background jobs happening which should not involve React at all.
That's what I got too:

Dude, you really need to learn how western countries work.

Majority of policies in China, especially economic policies, China learns from either HK or Taiwan, then they are learning from either US or UK.

Like the stamp tax you mentioned, you know what it is if you trade stocks in HK or UK.
> Therefore we've raised the social cost of a divorce until it's only accessible to people who really need to get out

I don't know what the time frame for this statement is, but all over the western world, divorce has been made substantially easier both legally and socially, since the end of WWII.

> Because of cultural changes, this doesn't work as well as it has in the past at keeping couples together.

Obviously culture and law are bound up together, but the advent of no-fault divorce and the decreasing benefits for the married over the unmarried did far more to make divorce easy, common, and therefore more acceptable than easing the stigma ever did directly.

> I don't understand why manufacturers (and their customers) consider it OK to ship broken DRAM chips that do not conform to their stated specifications.

Because they can, and sucks to be you. This is how things are everywhere. For competitive markets, the only real quality pressure is regulatory and contractual (and maybe reputational, sometimes). There needs to be a direct feedback loop between the value end-customers care about and the profit of producers/sellers for that value to matter.

As a random and interesting example of this phenomenon (really seen everywhere), here's something I learned yesterday: according to Derek Lowe[0], there's no graphene supplier anywhere that actually supplies you graphene, and they all tend to lie about it. Apparently this is one of the big things that holds graphene research back (and probably invalidates a bunch of papers).

Ask HN: Are modular neural networks an interesting avenue for further research?
Modular/Multiple Neural networks (MNNs) revolve around training smaller, independent networks that can feed into each other or another higher network https://en.wikipedia.org/wiki/Modular_neural_network

In principle, the hierarchical organization could allow us to make sense of more complex problem spaces and reach a higher functionality, but it seems difficult to find examples of concrete research done in the past regarding this. I've found a few sources:

https://www.teco.edu/~albrecht/neuro/html/node32.html

https://vtechworks.lib.vt.edu/bitstream/handle/10919/27998/etd.pdf?sequence=1&isAllowed=y

A few concrete questions I have:

Are there any tasks where MNNs have shown better performance than large single nets?

Could MNNs be used for multimodal classification, i.e. train each net on a fundamentally different type of data, (text vs image) and feed forward to a higher level intermediary that operates on all the outputs?

From a software engineering perspective, aren't these more fault tolerant and easily isolatable on a distributed system?

Has there been any work into dynamically adapting the topologies of subnetworks using a process like Neural Architecture Search?

Generally, are MNNs practical in any way?

Apologies if these questions seem naive, I've just come into ML and more broadly CS from a biology/neuroscience background and am captivated by the potential interplay.

I really appreciate you taking the time and lending your insight!
