Ask HN: Can someone explain how kudu works?
So I discovered this website http://kudu.io/

Wondering how they can afford to have someone dedicated to my campaign without charging hourly price.

I signed up and it looks like basically someone dedicated to look after my campaigns!

Can someone explain a big picture of what kudu is doing?

How are they able to find "experts" (outsourcing), but keep the costs to a monthly fee, unless they were hiring someone overseas $5/hr.

Overall, trying to figure out what's really going under the hood at kudu.
There's reasons for charging $10 per domain other than the cost of the DB line

One thing I can think of off the top of my head is that it makes domain squatting a bit more expensive. $10 instead of 2c is 500 times less domains for the same amount of money. At the same time, $10/year is a reasonable entry price for "I'm seriously considering using this domain"

Domain names are a scarce resource, it makes sense to charge a good amount of money for them
How to Play Any Movie with DVDFab Media Player
I had to do this back when I used GoDaddy just a few months back. I was able to verify all of my domains but one. For whatever reason I'd click on the link in the email, go to the page, verify it then get another email a few days later since I didn't verify it.

Fortunately it was a domain I was going to let lapse so I didn't bother trying to deal with their support but I swear I verified it 3 different times and never once did it say it successfully went through. Very frustrating experience.
Sure, but you're not participating if your company participates, that's my point. An individual is separate from the company they work for. Microsoft as an entity can't request a certificate, sure. An employee that was involved in the seizure can't, sure, same deal. But an employee that had absolutely no involvement in the seizure but happens to work for the company? Nothing in that language says that they'd be banned.

I also highly doubt the scale you're talking about. I doubt that "many" employees are involved in a seizure. It's a sensitive matter, in the best interests of everyone to keep it as contained as possible.
If you wan't to build a website where users can log in and store their scores, you'll need to learn a web backend language too. I would recommend this Udacity course (https://www.udacity.com/course/developing-scalable-apps-in-j...) since you plan to learn Java anyways.

This would be intimidating at the beginning, but you seem motivated enough to survive it. :)

Overall, I feel like you are on the right track. Building projects/games/websites would lead to better learning.

What about programming, for example? It's entirely abstract and not necessarily have any visual representation. Programming is best learned through examples. E.g. "here's a line of code, here is what it outputs. Now try to figure out what the rules of the language are."

In the case of this article, the NN isn't being asked to do any abstract task like "decipher meaning", but the very concrete task of "predict the next word". As the article shows NNs can do this fairly well.

There is also a evidence that they can learn very high level knowledge about words and objects. See the success of word vectors: http://technology.stitchfix.com/blog/2015/03/11/word-is-wort...
I'm confused how software is so different from any other type of invention. If you've ever backed a single Kickstarter project you're being hypocritical.

I'd much, much rather code be a "trade secret" than a patent. It's how closed source should work.

It feels like you're arguing semantics - it says "trade secret" so you're put off. If it didn't say anything and was just closed source... would you care as much?

Nothing in this world requires you to like or participate in anything else - you don't have to donate or participate. But the level of entitlement is off the charts.
> That mammalian brains are motivated by optimization of energy expenditure. Like anything in biologically evolved systems, energy efficiency is key, since food is often scarce.

That doesn't square with empirical reality. Evolved biological systems appear to be optimized for robustness to perturbations, not efficiency (John Doyle argues that there is in fact a fundamental tradeoff between robustness and efficiency, for all types of complex systems not just biological).

> how do mammalian brains problem solve using just thoughts.

They don't. Sensory input is required for brains to learn new classes of problems.

> find a way to train RNNs that are able to adapt to new problems

Is this something different than multi-task learning?
I saw a great short film called Delta Dawn at the Banff Mountain Film Festival. Unfortunately, all I can find is a short clip. Even the filmmaker's website doesn't seem to have it (or the page won't load properly).

The article author's comment about driving the Colorado reminded me of the filmmaker riding a paddleboard all the way to Mexico on the river.

Wait, I think you and I are having very different conversations.

If the topic you're discussing is that the clients of an OS API should not encounter a bug...uh, I mean, I don't think you'll find anyone to disagree with you. It's not like Microsoft engineers put that bug in there thinking it would be OK. They even acknowledged that it was a bug...it just wasn't high priority because the caller (presumably; again, I know nothing about these syscalls) is not following best practices. Someone's pet bug got deprioritized. This is not news.

The topic I thought we were discussing was whether it's the OS's responsibility to prevent callers from misusing their APIs in a way that causes stupid things to happen, even when the caller is doing something stupid.

I think the latter is a more interesting conversation, but I apologize if I interrupted your discussion of the former.

> And since most sites aren't actively hostile to their users,...

What web are you browsing? Tynt still exists. "Give me your email" popovers exist. Many sites won't display a simple 1000-word article without loading gobs of JavaScript I don't want. Websites are so terrible that most browsers have a "make the content readable" button. Most of the web is actively hostile.
Erlang has no string type. Most strings are a list of integers (any size), you can put Unicode code points there if you want, or integers less than 255 if you prefer. There is also a binary/bitstring type which is an array of bits (if a multiple of 8, it's a binary). You can put whatever you want in a binary, it's binary.

If you'd like things encoded in some way, that's up to you, there is no type to help you (there is a Unicode module which can help convert between encodings)
shared_buffers is the setting you're thinking of here.

effective_cache_size should be set to a reasonable value of course, but it does not affect the allocated cache size, it's just used by the query optimizer.

Lambda is good at discrete units of work, in an application already integrated with AWS, that may come either frequently or infrequently, where you don't necessarily want to have an app server running the whole time. Things like

- generating a thumbnail for an image uploaded to an S3 bucket

- processing in response to queue events

- generating stats and metrics on a schedule or in a response to events

I covered a bit more of why in the first article here: https://www.conetix.com.au/blog/what-is-docker

Do you deploy individual services to isolated AWS instances or are they on the one instance? Do you ever hit dependency issues upgrading some of the services? Do you ever hit the "worked in development" type production pushes? If so, Docker may be of interest to you.

Of course, if it's not broken then you don't need to fix it. Docker can't solve issues if they don't exist in your environment and it's not a 100% fit for every scenario. It's still worth having a play so that you know how it all works, once you start using it it'll make a bit more sense.

Absolutely. I have a few domains registered with Dreamhost too, and I almost didn't bother to check because I was positive that email was spam. And the Dreamhost reps couldn't be bothered to write more than a few words about it on the forum. Namecheap and a few others seem to be sending out identical emails.

VirtualBox is irrelevant.

VMware is closed source. The real Xen alternative is KVM. KVM is better than Xen in pretty much every way. There's a very big cost for big Xen shops to switch to KVM, but if you're not tied to Xen I can't imagine why you'd use it when KVM is better in every way (kernel integration, tooling, performance, etc).

I have a (crappy) screwdriver with some bite marks on it from doing that to come 1000V caps in an old panasonic stereo amp. It can work. It's not a good idea, IMO.

What I believe is safe enough for me to do... but not so safe that I'd recommend anyone else do it... is to measure the voltage between the high voltage supply and the ground in the amp, and see what you'll be getting if you touch it. If it is more than a volt or so, then connect a 10K resistor between the HV and the ground.

That said, if you don't understand why you should do that (or why taking life and death electronics advice from strangers in a comment thread is a bad idea), then you might want to just not get around in there, because you can lose fingers or even die if you don't know what you're doing.

:D Go circuit bend a speak and spell or something, and leave tube amps to folks who want to know more whys before touching stuff. :D

Except for every single "prepackaged developer's workstation" solution I've seen so far. Seriously it works on all systems more or less the same, so I see it used all over the place.
Stuck in a redirect loop
After resolving symbolic links that turns into "mv bar foo", which is perfectly acceptable since they are siblings. The checks for the destination being a descendant of the source should be performed after symlink resolution.

There's nothing in the standard about rename()'s error code priority (it could be EXDEV or EINVAL - they are not mutually exclusive), so I'd consider that a bug too.

Eddie Van Halen has always been an inspiration for me musically, arguably one of the greatest guitarists to ever live. Us modern guitarists don't realise how good we have it, we are living in a golden era of music technology.

I think for me one of the most influential and original ground-breaking guitarists would have to be Link Wray who was obsessed with fuzz/distortion and quite famously on his hit Rumble achieved distortion by puncturing his speaker with pencils to make it crackle. It is debatable who invented distortion, Wray was a pretty experimental guitarist.
Exactly, with these "high uptime" requirements, isn't it usual to have 2+ HAProxy instances running on different servers bound to the same IP? At least that's how I do it. When you update the config, first update the backup HAProxy, then update the main one. Any requests that take place during the main proxy restart would go to the backup.
> I'd much, much rather code be a "trade secret" than a patent.

These are not the only two options. If I understood it right, the programmer is asking for money to develop something that will be available for download for free, but whose source code would be secret.

As a programmer myself (who writes free-as-in-speech software), the source code is the most relevant artifact and the only one that interests me. I would not sponsor the development of a project where the only deliverable is an opaque binary executable where other development models are possible.
Making Computer Science More Inviting: A Look at What Works
Neat idea but I don't get how it works with feature rollouts. If Gmail is updated which changes the DOM and breaks the API how does the SDK handle being updated when it's rarely a change that's rolled out instantly for all users (usually takes some time maybe even weeks). I mean you either have a TON of feature testing to figure it out or you let it break; neither of which seems very maintainable to me.

What's going to happen with the rumored update? I've been hearing rumors for over a year now that gmail, calendar, contacts and even tasks are being majorly overhauled; is there any collaboration with Google to make sure when (or if) these rumors come true that it won't simply break everything day one?

Trying not to be a nay sayer; this is a great idea if you want to quickly add something to Gmail without messing with the Gmail DOM yourself but it doesn't seem to be a good long term bet to me.
Boy Scouts’ President Calls for End to Ban on Gay Leaders
I don't know if that's true. We already have a name for the time that is tied to Earth rotation, "UT1". Users who care about positions of astronomical objects can refer to that. UTC was always a bit of a compromise, which partly tracked UT1, but only up to the nearest second.

On the other hand, I think the idea of abolishing leap seconds is to no longer derive wall time from earth rotation, and to derive it from atomic time instead. So "UTC" would still refer to "the source of wall time". As I understand it, this is the point of changing the derivation of UTC: there are lots of laws in different countries that say that wall clock time is tied to UTC, so if we want to switch from earth rotation to atomic time, it is easier to change the definition of UTC than to change the laws in all those countries.
Palo Alto to Enforce the Largest Mass Displacement of People in History of City
I use rsyncbtrfs [1] (which I'm also the author of) to auto backup my OS, home and pretty much everything, daily. It's saved my ass on numerous occasions where I've deleted a file by mistake and could go back to the previous night's backup to restore it. Backup is where btrfs really shines. I have some 1200 timestamped directories, each of which represent a snapshot of my data at a certain date. I can just cd into them and look at the files.

It allows you to bundle your entire app and all the specific OS dependencies into one container to deploy it consistently on anything that supports Docker. While you might have your scripts to fit your needs for setting up your servers on AWS, what if you have users that are trying to deploy your cool app don't have access to your scripts or the understanding to even use them if you handed them over? What if you could ensure that your app was 100% setup correctly with everything needed regardless of the underlying OS? Docker helps make that happen.

The best example I can personally give you that shows the value and power of docker is with my experience with the forum software Discourse [1]. Being an Ops guy, I wanted to install it on CentOS 7 without their Docker setup and it took me a lot of time and effort to get it to work correctly. I recently set it up again for a demo for a group of people to check out and I didn't have the time to do a manual install, so I used their Docker method. I had it up and running in under 30min on CentOS 7. It was great and updating the forum down the road was very easy as a result of using the Docker method too. My manual install has a bunch of work involved to update it correctly and as a result, I don't updated it as frequently.

Ask HN: I am moving to Denver. Where should I live?
I am a software developer and I am moving to Denver in August. I'm wondering if anyone who currently lives in the area (or has in the past) could share their opinion about different neighborhoods in the city.

I am currently considering Capitol Hill based on input from some folks who have lived there in the past.

Some things I enjoy: general tech/nerd stuff, start-ups, snowboarding, board games, video games, beer, pizza, music (playing and listening), reading. Also, puppies, and long walks on the beach.

- Where is the tech scene focused in Denver? Is there a single dense area, or is it more spread out?

- Where are the co-working spaces? Which are good? (Google led me to http://densitycoworking.com/ and http://www.modworks.com/)

- Where are tech meetups usually held?

- Bars within walking distance?

- Are there any areas to actively avoid? Why?

I appreciate any and all advice. Also, I'd love to grab a beer with anyone interested in meeting new folks once I get settled. If you're interested, shoot me an email (in profile)!

> Could we expect a child to learn to speak if they only heard recordings of existing speech with otherwise no human interaction/feedback - correcting them or offering customized and contextual new bits of information?

I once asked a similar question on some online forum [1] where many linguists hung out. My question was if an English-only speaking household left a general interest Spanish language TV station on most of the time when they weren't actively using the TV to watch something, so that their child received a very large exposure to Spanish language programming (news, sports, soap operas, sitcoms, movies, etc) from birth onward, would the child naturally learn Spanish?

I don't recall for sure what the linguists who responded said, but I think they all said the child would not learn Spanish from this.

[1] I have no recollection of where this was.
