Hey, Gradescope dev here. What detaro said is on the money -- we're able to group identical short-answer responses so that they can be graded in one shot. It's not necessary to analyze the answer content for this.

Many (though certainly not all) of the instructors using Gradescope are teaching CS or Math courses with heavy enrollment. So each exam will have many submissions (even 1000+), and each submission will have a lot of short answers. Marking each one on its own is tedious, but until recently it was the state of the art for paper exams.

Instructors can and do grade essays on Gradescope, and are able to save time. But in that case the savings comes from being able to create rubrics on the fly, to change point values without re-adjusting every single marked paper, to grade across questions rather than across exams, to publish grades without having to type them all in, and so on.

There's a lot of grunt work that goes into grading, and it doesn't need to be the case :)
In the US, the federal government has acted in a big way to prop up home prices when they threatened to fall.

It's hard to imagine how we can have it both ways: If the government effectively insures real estate against loss, then investors (i.e., people with money) will take advantage of that, increase demand, and raise the price of the investments (i.e., houses you and I want to buy).

Ignoring all the fascinating stuff about Jupiter, let me point out this gem: The download of six megabytes of data [...] took one-and-a-half days

I sometimes like to scare kids by telling them about the time when I surfed the Internet with 14.4 kbit modem, but even that looks incredibly fast compared to the speed of interplanetary data transmission (back then, 6 MiB would have taken me about 2-2.5 hours).

(NB that I am not complaining or anything, just pointing out that this is many orders of magnitudes slower than anything one would normally consider a "slow" connection.)

No. As a researcher, you can make it your goal to find/invent a smallest possible architecture for a given task (in terms of number parameters, or number of operations). Alternatively, you can try to invent an architecture to learn faster from data (or require less data to achieve state of the art results).

I took Information Retrieval 101 in grad school and it was an interesting course. If you're curious to learn more, term frequency–inverse document frequency (tf–idf) is a good place to start. The underlying idea is surprisingly simple.

It's difficult to give feedback without knowing what the product is.

That said, the tradeoff most startup developers have to deal with is how to balance quality vs time. At every stage of funding, this shifts more and more towards stability being important, but until you have users, you really just need to get the very basics working okay enough.

Not all developers are good at accepting this approach. I even know of good developers that are not good at this approach, because it sometimes requires prioritizing product and instantaneous business needs over software engineering principles. However, it's really the best approach because most code you write today won't be there in 6 months or more as your understanding of the user and their problem(s) evolves.

It is not an insult to your co-founder, if he's choosing not to work under this style. Perhaps considering contracting out building the prototype or learning to code yourself.
Neat thank you for sharing. Out of interest what's the biggest thing you've changed after reading these books?
Interesting, but hard to draw any conclusions given that there were probably several other things that were different between the two implementations.
Representatives are a good way to create specialists who can investigate, and care about the decisions that need to be made.

Democracy is a pretty horrible way to select representatives.

In the US, democratic selection tends to select white male lawyers at a rate way above their presence in the population.

It means that our representatives are really only representing some sort of average ideology, not the actual distribution of beliefs.

I think a lottery (like long term jury duty) would be a much more effective methodology of selecting representatives who are representative population they represent.

Right, but doing this for HTTPS URLs would change the semantics of those URLs. People expect HTTPS to mean you either have a trusted CA certificate or you see a big, red warning. Changing these semantics would be terrible for security.

You can argue for opportunistic encryption in HTTP, but I'd argue that it's cheaper and easier for most affected parties if browser vendors just help push the price of publicly-trusted certificates to zero, which is exactly what Mozilla and Chrome (among others) did. Rolling out a new protocol would've taken years as well, so I don't think we've lost much time choosing this approach.
It's a great optimistic plan, but in practice, most don't. It's probably overkill for most very early stage startups.

That would be much more difficult to enforce. You'd have to hire people to walk around knocking on doors or have neighbours snitching on each other. No thanks.
Yeah. If the properity is passing you by and you're getting priced out, you have to move. Simple as that.

It's not a particularly kind thing to say, but it is what it is. Can't afford a car anymore? Sell it. Can't afford a city anymore? Move.

And before anybody says that some people can't afford to move, that's why you have to save money. Immigrants, who get by on far lower wages than we do, manage to save enough money to make it to America. Having savings allows you to preemptively avoid problems like this instead of being forced to take the problems as they come.

I think you are proving my point... AOO was "plundered" by LO but LO never gave anything back. So any "co-opporation" was extremely one-sided and one-direction. It was hoped that LO, as good FOSS neighbors, would donate back, even though they didn't have to, just as we hope that our corporate neighbors also donate back. We trust in altruism rather than in forcing it. It just so happens in this case that our trust was somewhat misguided.
other approach is issued ColoredCoin by banks - Lykke.com does this. then you get pricing of assets. fiat money are already "settlement coins", the question is about liquidity, risk and openness.
I agree its a silly argument but so is the theist's argument that says God (or whoever) provides for humanity through creation and then goes on to blame the harmful parts of nature on corruption of creation by Satan or the devil. I was raised in that kind of environment and have heard these arguments. Their 'logic' is almost always silly. Sometimes you got fight silly with silly.
As I recall Sun and IBM had a contract cause OOo was used for Lotus Notes. Then Oracle bought Sun. Oracle had obligations to IBM from that contract. Oracle could not figure-out how to make money on OOo so wanted to get rid of it. Oracle offered it to IBM but IBM did not want it. Instead IBM suggested ASF take it on. So Oracle relicensed under ASL and transferred everything hence Apache OpenOffice was born. IBM provided most of the devs to the project at that point, even hired some Star and Sun folks for it.

While this was all happening LibreOffice formed from... what was it... Goo go or something like that, the folks that were behind the build system and distro patches that most people outside of Solaris were actually running. I have a suspicion that there were terms agreed to between IBM, Oracle, and ASF that prevented ASF from donating anything to anyone.

Now IBM has scaled back support and at this point it's an LGPL v APL religious war.
Edit: TL;DR: I'm not saying TLS is fundamentally broken.

Also: Unless you need to support fucking ancient client devices/user agents, I urge you to drop SSL (and upgrade to as recent a TLS version as possible)

Re-read what I wrote, and what I replied to.

A lot of DNSSEC/DANE detractors claim that its effectively useless and unusable, because currently a lot of DNS stub resolvers (e.g. home routers) don't do DNSSEC verification.

My response is that you can use the same argument to make anything useless, if you introduce a terrible implementation.

Let's try a different example separated from certificates to make it clearer:

IE6 was a fucking terrible web browser as far as web standards go. Therefore, web standards are useless and should be abandoned.

So, how severe should warnings be for untrusted certificates and for plaintext?

For untrusted certificates, the answer is clear: very severe. If https://www.facebook.com suddenly has an untrusted certificate, it is almost certainly a case of MITM. The typical end user is not in a position to make an informed decision about trusting it anyway "because it looks right", so the page should just be blocked. In current browsers, bypassing these warnings is very cumbersome. And frankly, making the warnings less conspicuous would be irresponsible.

Now, you may argue that plaintext is even worse than an untrusted certificate. But whether we like it or not, in today's internet a browser cannot just block all plaintext connections. Making plaintext warnings as conspicuous as untrusted certificate warnings is unrealistic.

That said, there are other steps browsers could take to keep pushing https. Browsers could warn when transmitting passwords unencrypted. And, I don't know if it goes too far, but perhaps browsers could even deprecate persistent cookies for unencrypted connections.
In my experience, Apple actually warns about renewal before they renew. This is something I have yet to see with other major services. Hopefully it'll stay in and other services follows suit.
Are there any other books that are as inspirational? I very much enjoyed reading those ones.
The problem is not specific to foreign investors. Local investors are also more than capable of buying up perfectly good homes and letting them sit there vacant and unused. Whether the people are foreign has nothing to do with it. The problem is that society tolerates this practice of investors swallowing up housing, pricing people out of the market, and then leaving perfectly those good homes vacant.

Couldn't the solution be simply to enact a sufficiently punishing property tax rate on property not owner-occupied for more than 300 days of the year, so that these "investments" lose money? That would stop the practice, and maybe we'd see actual people/families moving in again.
I would welcome key usage constraints to limit a wildcard cert to https only.

But yeah I do hope you're right. I'll switch my domain off self-signing the moment a trusted CA offers a free wildcard cert with elliptic curve signing.
