What do Data Scientists use to train models fast?
i'm training a machine learning model using SVM in python and it took aages for it to happen on my local machine. (with 10% of the data that i have)
i'm getting a 80-90% correct prediction score on the same subjects data so now want to add in the rest of the data. (11 more subjects)

i thought of offloading it to my ec2 instance but i'm on a budget so cant just take a 30CPU instance..
on top of everything the code just uses 1 CPU at 100% always so i'm not sure about how effective it would be.

what do you guys use to train these models?

This particular gentleman also lucked out in the early wealth lottery as well. Mr. Money Mustache is a frequent example brought up in most every "this is how to retire" threads, without mentioning that he was able to somehow accumulate over 3/4 of a million in the bank prior to "retiring".

It's also worth considering everything he (and his family) has given up to live on his "retired" salary - like health care, a permanent home in the city or suburbs, modern cars, etc.

In short, it's not just the rest of the world where this is not feasible.

I prefer not to spend my time proving and writing about how something is impossible. Find a way and it will most likely be a solution or path you could have never predicted. This is a fundemental principle held by companies that innovate.
It is beyond offensive to imply that 60 year old individual is worth less to society than a 30 year old individual, and that there are life-saving measures appropriate for the latter that are too costly for the former.
If you aren't too tight on budget, I'd recommend the Lulzbot TAZ Mini at the moment. It's sturdy and reliable. It's fully open hardware too.

I almost agree. From the article:

> However, the drug has still not been tested in people who are HIV-positive.

To be sure that this new treatment is useful you must try it in a double blind experiment with many patients for many years.

Now, it's only an interesting idea with some in vitro support, but it's no a real cure. The title "HIV flushed out by cancer drug" is an optimistic exaggeration.

> While my comment was a bit glib, new features do have a tendency to introduce complexity & bugs on seemingly entirely unrelated parts of software.

This is true. Given CUPS's modularity, I think this won't add too much complexity, though.

> I just hope that the 3d part of CUPS is easily removable... I'd hate to see it part of the common user experience, CUPS already has a reputation for a complex and bewildering UI as-is.

I don't imagine it affecting the normal user experience at all. 3D printers are still printers and presumably configured similarly.

Yes and the author tells a story about Western culture but I kept asking "how do you know?" Eastern cultures may have the same bias but without enough technological development over their history to actualize it at the same rate that we have.

If you can survive on the interest, the price of the underlying bond itself is not as important.
You're right. There is magic here. It's called 1st grade math. For this to work, income minus expenses must be much greater 0.

You don't need to be rich or privileged or win the "ethic and circumstances lottery" as you called it. The key is to live well within your means and save the difference. Saving 25x your annual expenses is something anyone (even someone making minimum wage) can do but it does take time hard work and the willingness to defer gratification. Do you really need that fancy vacation or the iPhone 10x++? Or do you want financial freedom at some point in the future?

It's your choice. Choose wisely.
The US is to a quite good approximation, the only naval power on the planet.
This attitude is exactly the problem. It's magical thinking.

Thinking "outside the box" when it comes to industry standards may be a path to innovation. Thinking "outside the box" when it comes to the laws of physics is a path to nowhere.
The two-lock waterway could take vessels with a proposed freight capacity of 25,000 20-foot containers, or 20-foot equivalent units (TEUs); currently the biggest ships have a capacity of around 19,000 TEUs and make up a tiny fraction of the world fleet. Even the expanded Panama Canal, due to open in 2016, is limited to taking cargoes of 13,000 TEUs, so ships that otherwise would have rounded Cape Horn or gone via Suez would be able to move more easily between east and west.

That's about the only reason I can see for building this canal.

>So my question here is if there a bare metal box and the max is 16 core for a VPS server can the web host dedicate 1 core to each user or the core is shared?

Yes, they can dedicate 1 core (or more) to a user. They just pin the VPS processes to specific cores per user.

Xen allows this for example: "vCPU Pinning for guests - You can dedicate a physical cpu to a particular virtual cpu or a set of virtual cpus."

What exactly do you find hard to believe?
Without looking I can tell you it's two reasons:

1) It's text based and, therefore, can keep its total response small.

2) The page is cached on the backend so database lookups are kept infrequent and small.

Those two reasons alone make it faster than, say, 80% of most web sites.

> I assume that VCs aren't going to throw 10 million dollars at somebody without doing atleast some due diligence.

This is a dangerous assumption.

VCs often trust founders more than they should, especially when it comes to areas the VCs are not knowledgeable. Add in an idea that would obviously be adopted everywhere, and the allure of a billion dollar idea overrides sanity checks.
> Who are the trusted partners? By whom are they trusted? I am certainly not the one doing any trusting right now.

In security, "trusted" has a very simple and straightforward definition:

Trusted (adj.) - Liable to create a security breach.

That's what it means, nothing more, nothing less. It means that YOU are going to have to trust these third partners to not screw you over.

Whether you know who they are or not, it means that you trust them with your private data.

"Trusted" is never a good thing. With proper security and privacy logic in place you shouldn't need to "trust" anyone.

Indeed it means that I "trust" the NSA (and local Dutch agencies conscripted by them) with any data that I send or receive that is not strongly encrypted. I don't get a lot of choice in the matter, so I'm going to have to "trust" they won't screw me over with it, sell it to bad actors, keep it safe for as long as they keep it. No it's not a very smart idea to "trust" them, but I don't get a lot of say in the matter ...

Personally, I tend to "start" working, then all of a sudden stop to do something else. It's not on purpose or anything, it just happens. I've started "stopping" myself when it happens, and trying to identify why I don't feel like working, and built up a profile of things that I seem to want in order to work. For me, it's:

- Dual monitors
- Good music
- Actual mouse

For the longest time, I was just never able to work on a laptop, until I realized that the problem was screen real estate and an actual mouse.
In addition to the other replies, there is also the ability to unify slicing from common formats into the data necessary for each individual printer.

I'm not up to date on the current state of the art, but 15 years ago industrial 3D printers required solid model generation, slicing using either some proprietary software or solidworks, and transmission to the device over network share, ftp, or sneakernet. Some or all of those parts could be common to a print system, reducing the scope for machine vendors, and allowing operators to mix and match components in interesting ways.
It's because it's only text with little to no JavaScript, and I haven't looked at the source behind HN, but presumably, the HTML for every URL is cached upon each change (comment, upvote) and requires very little processing time per user customization.
They respond with "hater" and claiming the "criticism is unfounded" because they have no real response.

Yes, but the underlying mechanism - the deletion in the CCR5 receptor coding fragment - is a known source of HIV immunity in humans.

The bigger problem here is that bone marrow transplant is by itself more dangerous than an antiretroviral-controlled HIV infection. Not to mention that CCR5 deletions are quite rare.

One approach is to convert the code to use parallelism. For an example of how to do it in Python using joblib see this article: http://blog.dominodatalab.com/simple-parallelization/

Even if you can't afford a 32-core instance, you might get to use 4 cores in your laptop.
I haven't done any real analysis of it, but I've always assumed it's because it renders up a single small HTML document rather than large core content and dozens of external references (ads, analysis, etc.).

Looking at this page in my browser's network analyzer, I see a request for the page itself (3.8k), followed by requests for the css and a few images which don't impact layout. On top of that, JS isn't used for layout, so the HTML renderer can do its job.
Compared to most newspapers and other sites using megabytes of Javascript, HN is blazingly fast.

Whenever I find myself on a shitty connection with high response time and (moderate) packet loss, trying to read a newspaper online is just painful, whereas HN mostly loads fine anyay.
My understanding is that China conducts significant resource exploration and production activities in the Gulf of Mexico and other areas around the Atlantic already.

Speed isn't everything. Hacker News has been recently one of the most unreliable website I frequent.
In addition to being so small (text-based, minimal JS), HN is cached by CloudFlare, which grabs copies of dynamic pages and pushes those copies out to their CDN edge servers around the globe so they're closer to end users.

When your browser asks for the IP to news.ycombinator.com, you get the address of a cloudflare CDN server. Which web server the DNS server will send you is based on a GeoIP lookup of your own IP address so that they can give you the address to the server physically closest to you, and therefore the lowest possible latency.

Edit: Apparently this is not how CF does things (see below explanation by benjojo12) but is not uncommon in load-balancing and distribution.

Anybody know how these companies continue to get money from investors? SolarCity, Tesla, Sun Edison lose money year after year. None of them are profitable. And they won't be for years. I guess the thinking is that once, or if, they get profitable they will benefit from being the established players.

Postive attitude does equate to "magical thinking".

Check with Einstein and others on what it takes to make breatkthroughs, discoveries and think outside the box in the context of science. With the attitudes of some, we'd never make discoveries!

What you're describing isn't a typewriter, it's a daisywheel printer with a computer keyboard bolted on front.

I learned to type on a manual typewriter in the 1970s. Unless you had somewhere north of $1000 for an IBM Selectric, or somewhat less for a second-tier knock-off, that's what you got. (Ordinary electric typewriters were basically a manual typewriter -- like the sim -- with motor assist for the type arms. They didn't jam as much and were lighter on the fingers and gave more even imprints on the paper, but still ...)

The jamming is a side-effect of hitting keys too close together so that the type arm from the first key struck doesn't have time to fall back and clear the space the second type arm is trying to move into. Experienced manual typists learned not just touch-typing but the correct rhythm to minimize the time between keystrokes without quite jamming the machine.

Not pulling in a ton of external javascript, images, and ads is probably the biggest, but one thing that helps is that most comment threads have a relatively low number of comments. This page currently only pulls down down 12KB (compressed to 3.75KB).

While I would agree with the general idea, I do not like the general tone of the post. It is as if this guy knew everything about ultrasound technology. A given idea does not seem to make sense ? Maybe it is just that you don't know enough about it.

Happily concluding that Marc Andreessen, Mark Cuban et al. are just dumb investors pouring their money into impossible products is a bit short sighted.

What objectively measurable difference is there between reflected and transmitted light?

Polarization might be different, but that's something that's only barely perceptible to humans. I don't think it's plausible that it could affect legibility or eye strain.

I can't get past the hubris involved with this post. First, did you truly need Haskell to learn that number representations have pitfalls? Look back in history. Problems with numbers did not begin with computers. Nor will they end with them.

Second, you imply that this would have been an easily solvable problem. If only those that came before you hadn't been so willing to shout "Hooray" and make a choice you disagree with.

I don't think you have to have respect for those that came before you. But blithely ignoring their context when they made these choices is... rude. At best. (It also ignores that many early computers did not use 2's compliment numbers, so it was possible to keep adding to bigger and bigger numbers, you would just run out of space and cause other problems.)

Finally, over/under flow are pretty much endemic into all physical things. Ever accidentally pour too much water into a cup? Why didn't you pick the correct cup for the domain of liquid you were dealing with? Overfill a laundry machine? Run out of ink in the pen you were using? Reach for a sheet of paper to find you had none left? ...
I just came to know that the site is using flat files and surprised. Is that still the case ? Why was such a design selected ?
that 1.2Mb gets cached. Infact that will make the site faster because once the .js are downloaded only json/partials will be fetched when visited again.

It must be the backend ,ie when tasked to render the same page ,which backend would respond faster
Climate Change Cause..Effect..Cure
Of course I don't have a background in science but whenever I walk into the woods on a hot day the temperature is quite a bit cooler. Usually startlingly, though refreshingly, so. I believe a large scale effort to plant forests would be a necessary step to take as well as focusing on energy. Changing our energy usage may stop the harm but I believe it's the forests that will heal. Forests also have a profound effect on the weather.

Of course there is the possibility that the Earth is heating on its own and there is nothing we can do about it anyway. But it still seems like planting forests and stopping deforestation would do about the only good we can presently do.
The IRC protocol is in a different situation to USENET, because the latter has many different independent, individually federated networks of servers, whereas the latter has just one.

This means that server-side innovations can and do happen - they just need to respect the basic server-client protocol. Often the newer features are delivered through "services", which means they're in-band signalled.
STUN is indeed used by SIP to traverse NAT, as part of a whole pile of techniques called ICE. However, this ultimately requires that you have a central server on which you can "advertise" your SIP presence and exchange SDP data. Yes, the session payload transport (RTP) is peer to peer, but the signalling still requires a central point.

> How can I get your js/css from outside, if you are behind NAT?

The same way you get the HTML, whatever approach is used.

I don't think it's impossible to build a system involving distributing "advertisements" saying how to reach systems on a distributed hash table, then using either ports opened through UPNP on home routers or a "supernode" collection of STUN servers to communicate to home systems. There are three big downsides to this which are probably why we've not seen one yet:

- no way to monetise it if it's truly distributed and open source => reduced incentive to build and maintain

- no central party to fight spam and abuse => system will drown in spam and abuse

- necessarily broadcasts an association between home IP address and person => vulnerable to privacy problems and DOS attacks
So, why hasn't anybody raised millions for a company making flying cars or other crazy but wonderful technology like that?
For your need to simulate a 256kbps connection, two things have worked for me. Both require a good few mbps connection to begin with though:

1. Use Chrome's device emulator mode. You can ignore all other settings like screen size, user agent, etc. and just use the speed restriction.
2. Use a specialized WiFi router. I use the ones from TP-Link in which I can restrict speed for a particular device IP. DD WRT based routers can also help here.
Facebook uses IRC for internal communication. They have custom bots and it's linked to their version control / deployment.
