Also check out this which has many of the datasets that NASA has for earth facing satellites:

qopp··on Users You Don’t Want
Can you check the first sentence under the section "Saying No"?
qopp··on Why we lost Uber as a user
Just to keep it in memory? Postgres does this already-- it will put tables or parts of tables in memory to speed up reads [1].

qopp··on Reverse Debugging for Python
I don't know much about pypy, but do you need to compile it each time? Just use pypy to live interpret the interpreter.
qopp··on Another Update
I'm happy that Gavan is Open Sourcing his work and that people are generally happy with the outcome.

That being said I would not be surprised if Gavan announced a brand new voxel project and kickstarter a few years from now, starting from scratch like last time.

qopp··on C++ for Games: Performance, Allocations and Data Locality
One comment: The “dragging a slider to the right” math is assuming all players that pay $25/month are playing the entire month non-stop. In reality it goes in waves. Using the "22.7 hours a week" from WoW, that's only 0.13/user/month. Cloud computing capitalizes on this by renting per hour to capture the waves. This means a 25$/month user is only costing $2.5 for server usage which seems right.
qopp··on Student Debt Dodgers: Americans Who Moved to Europe
I think the reason bankruptcy doesn't apply is so that lenders are more willing to give out student loans (which is good, more educated society, more opportunities) and also so they lend them out at a lower rate.

Without this, banks might require very good credit to give out loans (hard for young students to acquire).

The article is just recapping the description of and linking to this site:

qopp··on Is Craig Wright?
Both sides think their solution is decentralized and the other is centralized.

Big blocks wanted limited growth that still works on domestic machines. Big blockers believe in using Bitcoin as-is; small blockers want to "spam filter" (i.e. control) some transactions or use some third-party thing like Lightning.

qopp··on Lesser-Known Python Data Analysis Libraries
If you're looking for a simple data pipeline, there's pipeless: https://github.com/andychase/pipeless

Also reparse if you want to parse natural language with regular expressions: https://github.com/andychase/reparse

qopp··on Show HN: Simple Postcard – Send a photo postcard from a text message
They could contract one of those services to print it for them
qopp··on Apply HN: Time\2 – Elastic Time
One thing that I'm hesitant about is that people often use time-as-a-limited resource as a way of pushing people out they aren't interested in seeing or doing business with.

If people are buying time for other people (I'm assuming that's your business model), then people may be forced to simply tell the truth, which may harm some relationships/businesses.

Have you found someone willing to insure your startup against any possibly litigation?

qopp··on Apply HN – Madgigs "Staffing Accelerator"
Ah I see. I think you can use the term but saying:

> A Staffing-preneur refers to any Technical Recruiters who are entrepreneurs.

At the beginning would have helped me. It's always hard to know whether or not to use or explain buzzwords, but keep in mind proposals might be read by lots of different kinds of people, so it's okay to be cautious.

qopp··on [dead]
I went on the site, set age to 18 and set gender to female.

Instantly bombarded with messages and dick picks from some very nice men. I guess this is what's it would be like being a woman on any sort of dating site.

qopp··on Apply HN – Madgigs "Staffing Accelerator"
One thing that might be a friction point reading this proposal (it was for me anyway), is that I don't know what a "staffing-prenuer" is, and a quick google search raised more questions then it answered. Is it someone who starts a staffing agency like a restaurateur?

Sorry this might just be me; but I just wanted to let you know.

qopp··on Apply HN Free Labor...sponsored teams.
Perhaps it might be more profitable to simply seek out the most entertaining types of work going on around the community and live-stream it. This would remove the costly and risky aspect of managing the work "entertainment".
qopp··on Apply HN: CreatorsNest – On-Demand, Private Workspaces for Artists and Creatives
Do you plan to mostly focus on urban centers?
qopp··on Apply HN: Hostable, Reskinnable, Domainable, Searchable, Forum Software
You might consider implementing the features you seek as a plugin to discourse. As for the hosting expenses, there are 3rd party services that will host it for you.
qopp··on Apply HN: Hackinator – Allow hackers to invest in YC startups using code :-)
What do you think about the past startup Assembly? [1] [2]

qopp··on Being a “dumb” girl in Computer Science
To offer a counter point, why does the girl seem like she needs or wants someone to guide her along in each class?

Asking people to help is one resource, but so is reading the textbook, doing introduction tutorials, looking stuff up online, etc. The author doesn't mention she spent time doing these sorts of activities.

> Not only that, but other people in the room jumped in to help explain

I've definitely seen guys line up to help people in labs.

Maybe the take-away is that CS is traditionally taught in a very individual way and should be more group-oriented.

qopp··on LKML: New syscall: leftpad()
Actually this is an opportunity for left-pad.io. Previously they had to maintain custom code, but now they can interface through to the kernel which is much faster and allows them to scale.

Many people are on older kernels and might not be able to upgrade, or for convenience or other reasons simply prefer to use an api for their critical business logic.

qopp··on Changes to Npm's unpublish policy
This is uncommon, but in this case you can use your email address or github.io, etc.
qopp··on Show HN: Locent – Mailchimp for SMS
Is this service ethical?

I hope users who would like to see bulk messages on their phone chose to opt-in (manually, not auto-opt-in). Your terms of use do not demand this.

In the US: "FCC rules ban text messages sent to a mobile phone using an autodialer unless you previously gave consent to receive the message"

I would wonder deeply about opt-in rates as well. How are you keeping track of how much users enjoy receiving these messages? (Not just click rates because people might click something they hate to receive)

Also, confusingly, your terms of use state:

> You agree that You will not use the Service to send.. "promotional materials"...

But that's what's shown as an example on the front page?

qopp··on Is Bitcoin breaking up?
Bitcoin is interesting because it attracts comments like this. Make no mistake, there is a turf-war going on; a true battle of mass popular opinion.

People do good things and they do bad things; but for some reason Bitcoin has crossed the threshold of being technically understandable so people resort to trusting people instead of ideas; so you end up with a lot of narratives (on both sides).

qopp··on Let’s Encrypt Now Being Abused by Malvertisers
There are sites that do this as part of their core ui, such as deviantart.
qopp··on Disque 1.0 RC1 is out
Someone else could also do the analysis, Jepsen is open source

What about an svg?
qopp··on A visualisation of all of the money in the world
The number of bitcoin units is just a property of the number of decimal places that are used in each transaction. Bitcoin can actually be changed to support more in the future if needed.

This has no economic effects since you're just adding more ways to subdivide a dollar.

If you're looking for weaknesses, there's a list here:

https://en.bitcoin.it/wiki/Weaknesses

Deflation is more of an economic problem then subdivision; since it's very unlikely that can be changed.

qopp··on I fit the description…
The cops wouldn't have revealed the witness's race. The author likely didn't actually know who actually gave the cops the description that matched his.
