MS COM C++ style coding for those that are interested and curious about all the S_FALSE and STDMETHODIMP macros.

Thank you, thank you, thank you for this. Such an interesting look into the world of HFT. I particularly like the parte of tapping into the cable directly, looking at the first bytes of the packet, and sending the order before the entire packet arrived. Awesome stuff!

thks!

ah! thank you :)

how is this good for Bitcoin?

Shutdown exchanges in the US, South Korea, China and Japan and you'll see how quickly everything explodes. Just the mere suggestion that South Korea was about to do this tanked the market.

My point is that - as described - it is a dumb comparison.

> open source serverless platform which is faster than bare-metal code

does't make sense. It eventually has to run on top of bare metal (via hypervisor or directly), so claiming that something that eventually runs on top of bare metal is "faster than bare metal" doesn't make sense at all.

You need a point where the cryptocurrency changes to fiat (e.g. USD). At certain scale, you cannot meet at a venue and do face-to-face cash transactions. That is why those exist. Also, those are friction points where anti-money laundering programs and (light) anti-fraud regulations exist.

Not to be nitpicking, but Charles Ponzi and Madoff did fraud at global scale.

> nuclio is an open source serverless platform which is faster than bare-metal code

WTF? Can somebody explain to me what they are trying to convey here?

I pay $10/month for two accounts of their Google Apps services - and I still get tracked big time.

because in the world we live in there are only two practical options; Android or iOS. Yes, you can do your homework and spend serious time customizing either one through the numerous amounts of gotchas to increase your privacy. At the end it boils down to "do you want Internet, email and maps that work in your phone? Good, deal with all this then!". If there was a single option that offered all of this at a reasonable price, you would see a lot of people moving to this. It is a sad frustrating state of affairs that could only be fixed with laws that would be impossible to pass with the current US lobbying system.

The amount of downtime and how their wire has been for months says that

I am honestly torn. I have used kraken to make several thousands of dollars, but I am always at awe with myself for using such a shitty site. If any of the other exchanges could figure out how to validate faster, you would see an influx from people heading there just to avoid the common cloudflare errors that kraken users are used to seeing. I am tired of putting orders for thousands of dollars and having to refresh multiple times to see if they went through...

Why wouldn't you be able to train it to recognize expected behavior from a mockup? You could easily create a nomenclature of symbols to define standard behavior (⇑ could mean draggable upload for example). Even if you can get it to take you 80%, that would be huge.

thanks!

The second option can be hosted at ArcGIS Online without you doing anything (i.e. loading anything). It is a REST API. Yes, it is hidden in their stupid docs.

The third option is faster than anything else, but would require you to load planet-osm.

source?

Ahem:

- GRASS has had that since the 80s: https://grass.osgeo.org/grass72/manuals/addons/r.traveltime....

- ESRI has had those in web form since the 90s: https://doc.arcgis.com/en/arcgis-online/analyze/create-drive...

- GeoTrellis has that working in an open source project on top of a Spark cluster: https://transit.geotrellis.io/travelshed.html

Why limit to small business? Talk (not email) to a company with a lot of money and figure out their biggest pain point. That is how I would do it now if I had to start over

I get that traffic may be increasing because of demand, but I find it bizarre (and unlikely) that so many exchanges would not have planned for it.

If you had ever compiled some of these datasets you would realize that it was impossible to get the datasets without extremely complicated scrappers that generated jobs, waited for a tiny little portion to be extracted (like 0.1% of it), and download the result from an ftp location that had non-standardized names... or how you would end up just giving up, calling people on the phone to ultimately get the person in charge to return the call to you, and buy pre-filled HDs from them that would get mailed to you eventually.

This is far more than a glorified mirror.

Looking at the comments, most people don't understand what this is.

In the geospatial industry, there are many organizations that produce free open data.

For example the NAIP image data comes USDA and has been paid for by the US govt so the city/state can used it for agriculture - hence why the images are not just RGB, but they also include an infrared band so they can be used for agriculture algorithms like NDVI results. For that particular dataset the license is very liberal. In case you are curious about that particular problem, you can find more info here: https://www.fsa.usda.gov/programs-and-services/aerial-photog...

The problem with dealing with datasets of this size is that just the mere collection and storage of it, is a problem of resources. This AWS link here is saying that they have grabbed all these datasets from various govt and non-profits and are hosting them in raw form so you can use them. Because the data comes from so many different institutions, the license is different - but practically speaking super liberal.

It is not competing with any previous commercial service from any vendor, nor it is meant to be a solution of any kind... Just big public spatial datasets hosted at AWS.

During my first startup as the CTO I made the mistake of thinking this way. I was so wrong I burned through 2M like it was nothing.

The "product" of a startup is a sustainable business model that can scale fast. The core technology may or may not be a key element part of that model.

So they solved a customer problem with interesting technology - regardless of arguments if it ACID compliant, or as good as <replace with whatever you think is "better">.

Where they sustainable at the beginning? No. Are they sustainable now and did they scale appropriately? Yes.

As a startup that went through it stages, they did it. This is not easy because it requires all the elements to work properly (market need, sales, marketing, engineering, operations, etc).

So what if RethinkDB/or_other has a feature that is better? Irrelevant.

Even better they did this ethically, which is more than I can say about other "startups" with insane funding and dubious and questionable strategies.

Most people forget that with startups, what you are trying to create is a business... the technology behind is only one element to it.

It is extremely difficult to do good marketing and sales and they did it.

Solve a customer problem while building a healthy business... a success story in my book.

<sarcasm>And here I thought clustered index and a OFFSET was the solution</sarcasm>

Oh geez, if you want to play the linear game, you can even trace the Android development to the Roman empire.

To put the conversation back in a grounded and reasonable list of arguments, let's start with the premise that technology != business.

So even if the tech that Magic Leap is creating is so great, by the time they go to market, they will be competing with an ecosystem already in place. Apple will have all the apps that have been built with their ARKit (not to mention their App Store monetization strategy). Sony, FB/Oculus, HTC and MS are already at the infancy of developing something serious there. If Magic Leap came out with a product today, they are already starting behind.

If we take in consideration price point, it even becomes a more challenging scenario.

The iPhone was not built with venture money. Your comparison does not hold at all.

coming from someone whose house has burned down twice, take photos of everything. You will need it for the insurance.
