lqdc13··on Compute Engine machine types with up to 96 vCPUs and 624GB of memory
Isn't it what beowulf clusters are for?

It's never cheaper in the cloud.

lqdc13··on A Large-Scale Study of Programming Languages and Code Quality in GitHub (2014)
Also the way one works in the various languages is different. Some people are more likely to push barely working code to github because of the language's culture.

Perhaps timing should be considered as well - how long it takes to implement a feature including fixing its associated bugs.

lqdc13··on DuckDuckGo vs Google
I burst out laughing, thinking they were trolling. But it's a real product.

lqdc13··on Top medical experts say we should decriminalize all drugs (2016)
That's not true. Usage increased[0,1].

- Reported lifetime use of "all illicit drugs" increased from 7.8% to 12%, lifetime use of cannabis increased from 7.6% to 11.7%, cocaine use more than doubled, from 0.9% to 1.9%, ecstasy nearly doubled from 0.7% to 1.3%, and heroin increased from 0.7% to 1.1%

lqdc13··on Alphabet considers Lyft investment of about $1B
In San Francisco Lyft is cheaper.

SF center to SFO is like $15-35 for Lyft Line while Uber charges $19-45.

SoMa to Marina is $4.05 for Lyft today and > $5.50 for Uber

lqdc13··on Quadratic voting (2014)
What if the status quo keeps moving in a direction that slowly makes things worse for a certain group of people?

You basically cannot get out of it unless you can convince most people that it's a good idea. With a 2-party system you can get someone who represents those people to rule for a while and maybe correct the course.

Also, with optional voting, we basically delegate decisions to those who really care about something. Having lived in a country with mandatory voting, I saw a few elections where people's views and the results of some elections were easily manipulated by false news close to the election day. People who are ambivalent I think are more likely to change their decision over such things.

lqdc13··on Quadratic voting (2014)
Wouldn't it also be a negative?

Basically, you cannot have radical societal or cultural changes because you have to get everyone on board ahead of time.

In a two party system and optional voting, you can have only a small fraction of the population who particularly want some changes actually get those changes. Also, this strategy can be used to destabilize a system away from local maximum (if we are searching for some better state).

lqdc13··on A backlash against the herbicide Dicamba
I think we're just talking about different things and my link wasn't very relevant.

If you actually visit the farms you can immediately tell the differences. When you visit a large farm, there is always things like tons of wasted space and water not covering some plants while others getting drowned. None of the plants are taken care of nearly as well as small farms (tomatoes usually aren't pruned for example). Overall, from what I've seen, large farms try to compensate for lack of individual plant maintenance by chemical treatments.

Here's a link to some "urban farming" that I think scales basically to other sizes: http://www.farmlandinfo.org/sites/default/files/Philadelphia...

Specifically, if you look at table 3, yield per crop area only decreases with size (1.2 for the largest farms and ~1.42 for the rest): https://seafile.entervice.com/f/175b18396c774698b6d2/

Then there is recent greenhouse indoor farming survey: http://stateofindoorfarming.agrilyst.com/

Here is comparison of revenue per square foot for large and small farms from that survey: https://seafile.entervice.com/f/c0a224916e6742ef9873/

It really depends on the crop but in this case everything but cannabis had higher yields in small farms.

Finally, if you're not convinced, here's some prose from cgiar regarding farm sizes and yields: https://wle.cgiar.org/thrive/2017/03/20/precision-agricultur...

select quote from there:

"In some ways, precision agriculture takes us back to the future. In some developing countries, very small farms tend to have marginally higher yields than somewhat larger farms. This can in part be explained by the relatively higher labor input on small farms, which can rely largely on unremunerated family labor. Under these circumstances, it is possible to check on every corner of the field on a daily basis, pull out weeds individually, and fertilizer precisely."

But here they're talking about very modern high precision farming which isn't actually taking place in many large farms. When it does take places it almost matches small farms.

lqdc13··on A backlash against the herbicide Dicamba
> Right now that is true

It isn't though.

> lower economic footprint, less land used per output, less energy spent per calorie

Small farms are actually a lot more efficient than large farms in everything but man-hours.

Think about it like this: If you had a 10 meters by 10 meters garden vs someone who had a 1km x 1km field. You would make sure every square cm in your garden is irrigated properly, that no insects are munching on your plants and each plant has the right amount of space and correct soil treatment for maximum yield. On a large farm, you cannot possibly do that. The total yield is a lot higher but the plants are not as healthy and are not living under optimal conditions.

lqdc13··on A backlash against the herbicide Dicamba
That's not true. Small farms are more efficient and productive per area. Therefore also more "green". I've read much about it but here's one link [1].

However, it is more efficient in terms of farmer-hours to have large farms and that's what really counts financially.

lqdc13··on Honda system confused by Alonso taking Pouhon flat
You're right. Didn't read your comment thoroughly. I guess I don't understand the general sentiment of why it is important that the actual show is as green as possible.

To me it just underscores the disparity between the feel-good green energy and the actual carbon footprint people generate. For example, it's a lot more "green" to not own a car than to own a Tesla.

I wish they kept racing a purely fun driver-focused endeavor and got rid of most of the electronics and hybrid tech.

And for those who love the tech maybe have a separate competition of self-driving electric vehicles.

lqdc13··on Honda system confused by Alonso taking Pouhon flat
This is all PR.

In bet now it's way more energy demanding than before just because there are way more people involved.

More journalists/media and many more support staff to work on hybrid tech.

lqdc13··on Honda system confused by Alonso taking Pouhon flat
I've been watching MotoGP recently instead of F1 for some of those reasons. Much more enjoyable, dangerous and unpredictable. And you don't go around an oval unlike indycar.
lqdc13··on Honda system confused by Alonso taking Pouhon flat
It's still manual transmission and they don't have traction control or launch control or automatic suspension adjustment.

I think they added the boost tech so that cars pass each other more frequently.

lqdc13··on Why PS4 downloads are so slow
I've gotten anywhere between 100KB/s and 60MB/s on the same ISP.
lqdc13··on Noam Chomsky Joins Faculty at University of Arizona
I've found that the book medium invites for a lot of opinions from an author and usually selective references to prove some point. Sort of the same reason that when you read scientific papers, you don't want to just read those written by a single lab.

When I want to find out how something works I usually read a meta analysis or a review in a highly rated journal in the field. That way you get to see everyone's opinions and arguments on the subject. They are usually written to be more or less accessible for people not in the field.

I hope they are very good, but it is not a good first impression if your UX framework web page looks like this on mobile:

lqdc13··on PyGraphistry – A library to extract, transform, and visually explore big graphs
Nice! Thank you
lqdc13··on PyGraphistry – A library to extract, transform, and visually explore big graphs
Is it possible to use a local GPU from the machine that has the data? Kind of like Gephi?
lqdc13··on Ad blocking is under attack
I mean it's unusable to the general public since IPFS network is not accessible via the browser without a proxy.

In other words, one would first have to integrate an IPFS client into all major browsers.

lqdc13··on Ad blocking is under attack
Still need some proxy for it to be accessible from the internet right?
lqdc13··on The BitTorrent Protocol Specification v2

lqdc13··on Bitcoin Exchange Had Too Many Bitcoins
Could be that people are more confident in BTC after they decided to do something about the slow confirmations. As in the value of the original Bitcoin jumped at the time of the split but was offset by the split.

Also possible that the split generated free publicity that made some people invest in it.

lqdc13··on Crack WPA/WPA2 Wi-Fi Routers with Aircrack-Ng and Hashcat
Why does that matter? 15 character digits-only password is impossible to crack really.

It's all about the length really.

lqdc13··on Crack WPA/WPA2 Wi-Fi Routers with Aircrack-Ng and Hashcat
Nowadays most routers I've seen come with a pre-shared key that's something like 20 chars long.

It's been the case with Comcast + Verizon for a while now. Not sure about AT&T.

Still might work 10% of the time though.

lqdc13··on Firefox marketshare revisited
It was the only choice.

Set your User-Agent to Firefox or IE Edge and Windows OS. You'll soon see "install chrome" pop ups/banners/warnings that take up a portion of the screen all over Google properties.

At that point why not just self-uninstall?

Out of non-Google search engines, Yahoo makes most sense even if they got no money from the deal. Maybe DuckDuckGo but unfortunately it's still not as good.

Regarding extensions, it's better this way because nobody is bothering with current API. Most new extensions are chrome-only.

lqdc13··on Cybersecurity Humble Book Bundle
I don't know.. It seems stupid easy to me. Try something like "Type the third and fifth letters of the word elephant into the box below" with instagram filter applied. A bunch of variations for the first part like "the following word" and "the word in parenthesis".

Basically, I can't think of a way to come up with something ez that defeats it. You would have to train a neural net specifically on these images because normally neural nets are bad at instagram filter removal unless trained on it. Plus you can slow down/ban/mess with requests based on cookies.

There are basically infinite solutions. Would take a couple of days to implement and would be really fun. I guarantee you: if your site gets maybe 30k visitors a week, nobody would bother spending a month cracking your captcha when there are much easier targets out there.

Finally, you can make it super annoying to actually find where the image is by converting to svg and messing with html structure/compose image in JS. Now they're going to be forced to run a headless browser, take screenshots of the captcha page and finding the image within the page.

If they take the pay-per-captcha approach, I don't think anti-captcha and the like would make it too ez. Still days of work to set up something really brittle.

lqdc13··on Cybersecurity Humble Book Bundle
You need a captcha to log in so that it's hard to make multiple fake accounts. You need captchas to buy stuff because otherwise one could make all accounts manually and then use them to quickly buy products to spend some bank account before it's banned.

I think each smallish site would benefit from designing their own captchas because that way the effort to solve for machines would be harder than solving the Google captchas. The effort to solve for humans would be a lot lower. This is perhaps one of the few areas where rolling your own security solution is beneficial by virtue of it being different.

lqdc13··on Net-glimpse: A little tool for network traffic visualization
You can do all those things in Gephi. Just give each node/edge those attributes and you can filter/query by them.

You can very much show desired protocol level details - just convert Wireshark XML to one of the common graph formats and load that.
