Given that 50 million catch the flu in the US each year would you say 1 in 6 people actually get tested for it or it's an estimation based on years of data.

I'd be incredibly wary of anyone claiming to know how many have been infected by a novel virus only discovered 3 months ago.

You simply can't estimate that with current data.

Not to mention the heavily tourist dependent countries in Asia that are willfully ignoring testing and updating the media on statistics.

Can you give me a concrete example of a massive distributed system that has zero downtime?

Because the largest distributed system I have seen and worked on was at Apple (or maybe DFP at Google) - and even though they had some of the smartest people in the world and literally billions of dollars behind them, there were still an endless list of problems and downtime events.

Spoiler alert: It doesn't exist.

Or it hints that the distribution of learning rates is not gaussian. When there's an "n-sigma" event, it's usually much more likely that the model is wrong than that the event is that rare.

Is this a real problem people deal with? People actually build these spaghetti services and deploy several versions of them at once? Each of these versions are somehow routable to and from each other version with no abstraction?

Surely this doesn't actually happen.
I think the credit-based system is the best compromise. It's even better if the cusomer can explicitly opt into an automatic top-up option, where they're automatically billed when their balance falls below a certain threshold. This is even better than the bucket model, as those who want their service running at all times won't risk running out of what their bucket offers, whereas those who don't want to control how much they spend can do the top ups manually.
Re your first and fifth points, how do the preliminary and final notes look like? Do you aim for 100% information coverage (or 95%), or do you only write down your aha! moments and have the textbook as the primary source of information?
I remember everybody at my work (Software Engineering) setting this up in 2002. The idea was kind of obvious, but at the same time so far ahead of its time.

It would be great if a similar project was set up to provide everyday, real world services like, say, internet search, or a distributed S3 clone.
Spot on. Looker is a great tool, but it has its own language LookerMl and a set of abstractions. From my limited experience it‘s not easy to pick up. It‘s likely that an analyst is already familiar with it. But like with any BI if there is a problem that can‘t be solved with an existing abstractions and tools, you either go back to writing the pipeline step to solve or you come with a very ugly solution.

> Apache Druid is supposed to be very mature, but also very difficult to set up and manage

I wouldn't be surprised if this inverted at large scale (say 30+ machines). Druid data servers are rebalanced automatically; if you're on AWS and decide to scale up by adding a new data server, it will automatically load its assigned subset of data from S3. If AWS kills one of your data servers, then other data servers will automatically load from S3 some of the data that server used to carry, in order to reach the desired replication factor again.

Last time I checked ClickHouse had no automatic rebalancing at all, which sounds horrendous unless you're running at very small scale or willing to have people babysit it. I haven't operated ClickHouse at large scale though, so if I'm wrong I'd be happy to hear how people manage ordinary tasks like scaling up and down, replacing dead instances, changing instance types to adjust CPU/mem/disk, etc... with let's say a 100 TB compressed dataset.

Another difference is that Druid can index all dimensions. So if you plan to run queries with filters that only match a small fraction of rows, then Druid can be faster than ClickHouse. Conversely, if your queries have filters that match many rows, then ClickHouse will be faster because it has higher raw scan speed. (At least that was the case about a year ago. Since then, Druid has added vectorized aggregation, which I haven't benchmarked, but I'd bet that ClickHouse is still faster at doing full table scans.)

IMO these 2 things are the main elements to think about when choosing between ClickHouse and Druid.
I find this comment actually more insightful than the GP.

How often have I talked with people and mentioned, that in terms of social behavior, we make such slow progress, if any. If we could end human greed and other bad things, how easy it woule be for us to go to space. If money did not count and all would work for a great goal of advancing into space, we would be there already.

What many call "human nature" (which I do not believe) is what holds us back.
I was curious why they banned it in the first place. From the article:

"At the time, RBI said the move was necessary to curb ring-fencing of the country’s financial system."

"It had also argued that Bitcoin and other cryptocurrencies cannot be treated as currencies as they are not made of metal or exist in physical form, nor were they stamped by the government."

The second argument is beyond weird as most currency isn't material these days, including India.

It's also worth noting that the ruling doesn't seem to have had any kind of effect on Bitcoin's price.

Maybe the news is too fresh ... time to buy !
You just can take any bootstrap theme. The component design is the basis of bootstrap.
Hi bananaboy! The system currently boots into 1024x768x32 by default. It uses the Multiboot protocol to request that the bootloader sets a video mode before passing control to the kernel. That allows the system to work in tons of places where we don't have a proper video card driver yet :)

As DAlperin mentioned, it's possible to boot it headless although it's not something that gets a lot of focus since this is primarily intended as a GUI system.

I have some presentation and "code tour" videos[1] on my YouTube channel where I go into great detail about how some parts of the system work. If you would like to know about the SerenityOS internals in-depth, it's a pretty good place to start. :)

The point isn't that "a system cannot fail", the point is "if the system fails, it's no big deal, shit happens, cut them some slack" is a weird way to look at it for corporate systems, especially in sensitive areas.

If you're running a HA system and you only need one nine to express your availability percentage, sure, sure, you have the smartest people etc and you're doing such a great job, and yeah, yeah, show me one system that has 100% uptime etc.
> But it doesn't actually correspond to any kind of real-world performance.

But it may correlate with performance, and that might be sufficient -- in the same way that Moore's law did for so long too
It depends on the type of service, setting up new accounts to dodge charges can be very annoying if there's any kind of data to move around, and it would be easy to spot for the service provider.
Nothing to do with that. This was Supreme Court decision and government will probably challenge it.

Even if Cryptocurrency helps in some dire situation arising out of COVID-19, facilitating cryptocurrency would be lowest of priorities for the government.

I can't agree with this article more.

The old style material field which were mentioned that are just an underlined text instead of a box were absolutely terrible too. It's disgusting that someone would actually think those were a good idea.

Also, what he calls out in the end, use high contrast guys! The old material design grey text on grey background was terrible to read. GCP used to be full of this.
While you can build machinery to do this. It is far easier to not. If you substantially want to change your api, just make a new one. Much easier to track migration between endpoints than it is versions in an endpoint.

And, in general, don't focus on generic methods.

The more specific a service method, the better. The less it does, the better. Don't have an "order pizza" api. Have a "start order", "add to order", and "complete order" api. If it helps, have multiple add methods. The parameters to add a pizza can and should be different from a salad. Even the pizza may be better served with partial service calls to start and complete.
It almost certainly doesn't. COVID-19 is looking more and more tame by hour as cases resolve and fatality rates drop. There's fewer active cases today than yesterday, and fewer still than the day before. We're 34% off peak number of active cases. Cryptocurrency is as scammy as always. Not sure one would distract from the other.
Echoing a comment below, with the fed lowering rates again it seems like loose money is here to stay for a while. I wonder if this will help eventually push adoption for cryptocurrency. Now I'm not a crypto-currency nut, quite the opposite, and I generally think blockchain is pretty useless, but you do have to acknowledge digital currency is finding uses in venezuela and a pocket of other countries where trust in the monetary system has completely collapsed. Continual low rates and high debts will for sure not wipe out trust in the financial system overnight but it definitely doesn't help
The impact of a collision is so devastating that any life surviving it is unlikely. Unless such life can endure such extreme conditions, in which case, it would exist on such inhospitable conditions as on Venus
I don’t see how this is a problem. I see that the combinatorial explosion exists, but that isn’t an actual problem. The entire point of microservices is independent deploys, meaning you literally only have two permutations per deploy, new and old. If you think deploying 10 services at once is feasible, you don’t understand the appral of microservices, and should never have opted for them in the first place.
Even in countries like Denmark we’re forced to deny certain cancer treatments because the cost of their medicine is so high it would cripple our entire healthcare system to buy a few patients 6 more months to live.

You can debate the morality of such a discussion, or how the private medicine industry is allowed to charge these prices, but the effect is that some cancer treatments are only available through private insurance or personal wealth, even in Scandinavian countries where we are know for our equal access healthcare.

It is worth noting that the initial ban predated by a couple of months to when they replaced all currency bank notes :

It had also removed higher value bak notes two years prior:

Both initiatives born out of curtailing criminal activities of various kinds at the time.

So the crypto ban happened during this period and may well of been born out of that initiative against crime more than anything else and now that things have settled down, the need for the ban became moot.

At least that is my thoughts upon this.

No country is recognising them as actual currencies, because once you do it, that opens a whole lot of other issues for the country, suddenly they could lose control on their money supply and that's a potential threat to their sovereignty. It's much easier and safer to consider them as assets.

Show HN: Entrylevel.io – Job board for entry-level positions
Hey HN,

We’re Kim and Donald from Entry Level (https://entrylevel.io). Entry Level, is a job board for students, recent grads, career changes, and individuals with less than 3 years of experience.

As current fullstack bootcamp students, both of us struggled to find jobs targeting beginners breaking into tech. Most jobs we would apply for require 3+ years of experience making it hard for us. We’d often go from website to website to find entry-level opportunities and I wanted to create a job board that has all the info I want from the multiple sites I visit frequently.

So we made Entry Level to help others struggling to find that first job like us. With Entry Level, you can search through all of our jobs from lots of different sources. If you’d like to apply for a job, it links you back to the source. How it works is simple, you just search and click on a job that interests you and apply.

We aggregate the data through the use of elastic search, but before that, we made multiple scripts that run on a cron job that gathers data from multiple sites. After gathering the data, the script then forwards it to our elastic search instance then we filter by a specific query that would filter all entry-level jobs. Then after the filtering process, we direct the data to our Postgres database and render it on our front end. Aside from that we also use other job boards APIs to increase the value of our content.

Goals for finishing MVP:
- Categorizing job titles - A lot of jobs posted on Entry Level are from a wide variety of categories. We want to niche down and focus on tech jobs as of right now.
- Pagination - Entry Level has hundreds of jobs within it’s database and adding pagination will help users find more jobs within a tech category.
- Searchable tags
- Site loading Async/Await
- Email Mailing List
- Post Jobs

We just launched our beta and would love to get your feedback!What would make your job process easier? Thanks!

> Why would anyone want retail investor order data?

Former market maker here.

Retail flow is low risk. If I buy $100mm of institutional flow, I could get a bunch of corporate hedging orders. Or I could make a single bet against George Soros. With retail, one tends to find lots of small orders. Even if there are some with high information, i.e. they're smart money and I'm going to lose money trading against them, they're small enough to be manageable.

Retail is also low information. At an old job, we bought a prominent retail broker's options flow. The number of in-the-money unexercised options that would come through that pipe was mind-blowing. (Today, whoever was buying Robinhood's flow likely got the same.)
This article misses the elephant in the room: how to define "reliability". Most software perceived to be reliable (eg, MS Paint, bash) have numerous bugs, it's just that no one comes across them. Software that is perceived to be "reliable enough" (eg, MS Word, Chrome), have bugs that pop up regularly.

Here are some vague uptime reliability measures and what you need to get there:

- 70% reliability: you can often just free-code it and pray.

- 95% reliability: you better have a bunch of tests.

- 99.5%: you need automated testing, coverage tools, documentation, team coordination tools, and and solid merge/deployment process.

- 99.99%: all-of-the-above plus tests that aggressively attack and analyze production systems (eg, Netflix Chaos Monkey), coverage tests that do branch coverage and not just line coverage, simulating network failures, and/or test on a variety of hardware and user-configurations.

- 100%: The only way to be absolutely certain, is to convert each line of code into a mathematical operator and solve for a formal proof of correctness.

The 100% reliability standard is not just theoretical. The U.S. government issues software standards for safety critical devices (military, aviation, healthcare), and some of them do indeed require mathematical proof of correctness (EAL6+ being a key standard). They generally do not require 100% bug-free code, but just that some particular features are 100% bug free (e.g., the OS/scheduler will never deadlock).
From talking to Indians the criminal element and the politicians in power were aware of this happening in advance so had already converted. Others powerful people did it after the baby with the help of corrupt bank officials that helped them back date stuff. So only the middle class bore the brunt of this.
Imo, that is identical to "microservices" but you're right that there's no reason to go any more than what you need. I always felt the whole microservice hype/movement was simply about defining multiple services as a useful pattern you'll want to use and how to build infrastructure to make it easy.

But I agree wholeheartedly. You don't need 100+ services to get the benefits of converting your tool chain to handle deploying n services even if n=3.
Those people don’t know what is pin risk. Basically their long puts got exercised because automatic execution is determine at 4pm and they didn’t object (creating a short position in equity), their short puts didn’t get exercised because the stock rallied by 5pm and their counterparty was diligent and prevented auto execution (thus no long equities position to compensate the short equities position). Robinhood couldn’t rebuy the short equity position because the actual price rose above the put price leading to a net loss.

> Customers know this, and are often apprehensive about these types of deal negotiations, so they tend to only go through this process if absolutely necessary

Unfortunately, for big enterprises, this isn't true. They (as a company, maybe not the individual developers inside it) want to go through it. They're the ones who start the RFP process, and as the service provider, you'll either follow their process... or they'll buy from someone else, no matter how much better your API may be.

It depends on the scenario, but this isn't as insane as it may sound. It's less relevant for, say, a SMS API which is interchangeable, but if you provide an API service that is deeply intertwined with the processes in that enterprise, the company needs to evaluate the different providers. This process is time-consuming one way or the other... they might as well let the different providers do most of the work for them (which makes sense, because they know their services).

As for the price negotiation itself: I agree.

Also, an enterprise sales process and usage based pricing are not mutually exclusive! You absolutely can sell usage based pricing, and both parties hopefully get the benefits listed.
> Both initiatives born out of curtailing criminal activities of various kinds at the time.

It is a well-accepted fact that demonetization was a sham at best, a scam at worst.

> So the crypto ban happened during this period and may well of been born out of that initiative against crime.

Again, what peculiar crimes exclusive to India are you alluding to that are suddenly extinct now? The ban was lifted because a successful court petition ruled the government is paranoid at best and out-of-touch with reality at worst wrt crypto.

At least, that is my thoughts upon this.
If you compare K&R C and C++17, everything that has been added is some form or another of 'proofs'.

So I take issue with the 'without proof' part; even if they're not proofs that adhere to strict mathematical forms, they're still there.
